     BACKGROUND 
     Field 
     The present disclosure relates to a hanger and a laundry treating apparatus including the same. 
     Discussion of the Related Art 
     Laundry treating apparatuses are apparatuses developed to wash and dry laundry or remove wrinkles from laundry at home or at a laundry shop. Laundry treating apparatuses are classified into a washing machine for washing laundry, a dryer for drying laundry, a washing/drying machine having both a washing function and a drying function, a laundry manager for refreshing laundry, a steamer for removing wrinkles from laundry, and the like. 
     Among the above apparatuses, the laundry manager is an apparatus that allows laundry to be kept tidy and clean. The laundry manager may remove fine dust attached to the laundry, deodorize the laundry, dry the laundry, and add fragrance to the laundry. In addition, the laundry manager may prevent generation of static electricity, remove wrinkles from the laundry using dehumidified air or steam, and sterilize the laundry. 
     Korean Patent Laid-Open Publication No. 10-2014-0108454, the subject matter or which is incorporated herein by reference, discloses a typical laundry treating apparatus. The laundry treating apparatus may include a chamber provided in a cabinet to define a space in which laundry is received, a door for opening or closing the chamber, a hanger support unit defining a space in which a hanger is supported inside the chamber, and a machine compartment in which devices for supplying at least one of steam or hot air to the chamber are provided. 
     In the laundry treating apparatus configured as described above, treatment of laundry (processes of drying the laundry, removing wrinkles from the laundry, and deodorizing the laundry by supplying at least one of steam or hot air to the laundry) is performed only in the chamber. That is, the laundry treating apparatus is not provided with a separate space for treatment of laundry other than the chamber. 
     Another laundry treating apparatus, which further has a function of supplying hot air or steam to a hanger, is disclosed (Korean Patent Laid-Open Publication No. 10-2016-0004539), the subject matter or which is incorporated herein by reference. This hanger-type laundry treating apparatus includes a fan/heater assembly for supplying hot air, a steam generator for supplying steam, and a water supply tank for supplying water to the steam generator. 
     In the above-described hanger-type laundry treating apparatus, the fan, the heater, the steam generator, and the water supply tank are disposed such that a straight line passing through the centers of gravity of the fan and the heater intersects a straight line passing through the centers of gravity of the steam generator and the water supply tank. The hanger-type laundry treating apparatus, in which a straight line passing through the centers of gravity of the fan and the heater is orthogonal to a straight line passing through the centers of gravity of the steam generator and the water supply tank, may have a problem that the hanger does not maintain a horizontal orientation when the amount of water in the water supply tank is reduced or when the amount of water in the steam generator is reduced. That is, because the steam generator and the water supply tank are disposed in the width direction of the hanger, the weights of the two opposite sides may become different from each other.

     DETAILED DESCRIPTION 
     A hanger and a laundry treating apparatus including the same according to an embodiment may be described with reference to the accompanying drawings. 
     Unless otherwise defined, all terms used herein have the same meanings as those generally appreciated by those skilled in the art. The terms, such as ones defined in common dictionaries, should be interpreted as having the same meanings as terms in the context of pertinent technology, and should not be interpreted as having ideal or excessively formal meanings unless clearly defined in the specification. 
     As shown in  FIG.  1   , a laundry treating apparatus  100  includes a main body  1  that has formed therein a cabinet chamber  12  defining a laundry treatment space, a door  3  that is configured to open or close the cabinet chamber  12  and has formed therein a door chamber  312  defining a laundry treatment space isolated from the cabinet chamber  12 , and a hanger  5  that is provided in the cabinet chamber  12  or the door chamber  312  to support laundry. Treatment of laundry means processes of drying the laundry, removing wrinkles from the laundry, and/or deodorizing the laundry by supplying air (heated air or non-heated air) or moisture (heated steam or non-heated steam) to the laundry, and the laundry treatment space means a space in which the aforementioned treatment processes are performed. The cabinet chamber  12  may be provided as a treatment space only for treatment of the laundry, and the door chamber  312  may be provided as a space for at least one of treatment of the laundry or exhibition of the laundry. 
     The main body  1  includes a cabinet  11  in which the cabinet chamber  12  is formed. The cabinet chamber  12  communicates with the outside of the cabinet  11  through a cabinet inlet  121  formed through one surface of the cabinet  11 . Therefore, a user may introduce laundry (an example of objects to be treated) into the cabinet chamber  12  through the cabinet inlet  121 . 
     A cabinet-chamber bottom surface  125 , which forms the bottom surface of the cabinet chamber  12 , may be formed in a stepped shape. That is, the cabinet-chamber bottom surface  125  may include a first bottom surface  1251  that forms a bottom surface of a region under which a first machine compartment  13  is located, and a second bottom surface  1252  that forms a bottom surface of a region in which at least a portion of the door chamber  312  is received when the door  3  closes the cabinet chamber  12 . 
     Therefore, laundry may be received and managed in a region above the first bottom surface  1251  among the regions in the cabinet chamber  12 . Additionally, when the door  3  closes the cabinet chamber  12 , at least a portion of the door chamber  312  may be received in the cabinet chamber  12 , and the door chamber  312  may be located in front of the first machine compartment  13  and the region in the cabinet chamber  12  that is located above the first machine compartment. 
     Therefore, a length between the top surface of the cabinet chamber  12  and the first bottom surface  1251  may be shorter than the length of the door chamber  312 . Accordingly, the length of laundry received in the door chamber  312  may be longer than the length of laundry received in the cabinet chamber  12 . 
     Meanwhile, the length of the first bottom surface  1251  in the forward-backward direction may be longer than the length of the second bottom surface  1252  in the forward-backward direction. Therefore, a greater number of laundry articles may be hung in the cabinet chamber  12  than in the door chamber  312 . The reason for this is not only to enable management of the laundry by selecting one or all of the two chambers according to the number of laundry articles, but also to prevent the laundry treating apparatus  100  from falling over due to the weight of the door  3 . 
     As shown in  FIG.  2   , the main body  1  may include a first partition wall  111  and a second partition wall  118  for partitioning the inner space in the cabinet  11 . 
     The first partition wall  111  may be provided to partition the inner space in the cabinet into the first machine compartment  13  and the cabinet chamber  12 , and the second partition wall  118  may be provided to partition the inner space in the cabinet into a second machine compartment  16  and the cabinet chamber  12 . Alternatively, the cabinet chamber  12  may be provided in the cabinet  11 , the first machine compartment  13  may be formed between the bottom surface of the cabinet  11  and the cabinet-chamber bottom surface  125 , and the second machine compartment  16  may be formed between the top surface of the cabinet  11  and the top surface of the cabinet chamber  12 . That is, the first partition wall  111  may be the bottom surface of the cabinet chamber  12 , and the second partition wall  118  may be the top surface of the cabinet chamber  12 . 
     The first machine compartment  13  may be located below the cabinet chamber  12  to define a space in which supply units  14  and  15  are mounted, and the second machine compartment  16  may be located above the cabinet chamber  12  to define a space in which a driving unit  18  is mounted. The first partition wall  111  may form the bottom surface of the cabinet chamber  12  and the top surface of the first machine compartment  13 , and the second partition wall  118  may form the top surface of the cabinet chamber  12  and the bottom surface of the second machine compartment  16 . 
     That is, the laundry treating apparatus  100  may include the cabinet  11  having the cabinet inlet  121  formed in the front surface thereof, the cabinet chamber  12  located in the cabinet to receive laundry or an item, the door  3  for opening or closing the cabinet inlet  121 , the first machine compartment  13  located in the lower region in the cabinet to define a space isolated from the cabinet chamber  12 , and the door chamber  312  located in the door  3  to receive laundry or an item. 
     Additionally, when the door  3  closes the cabinet inlet  121 , at least a portion of the door chamber  312  may be located in front of the first machine compartment  13  in the cabinet chamber  12 . 
     Therefore, considering the stepped bottom surface of the cabinet chamber  12 , a hanger support unit  17  may be located above the first bottom surface  1251  so as to be spaced apart from the first bottom surface  1251 , and at least a portion of the door chamber  312  may be located above the second bottom surface  1252 . 
     Accordingly, when the door  3  closes the cabinet inlet  121 , the second bottom surface  1252  may face at least a portion of the door  3 . 
     Additionally, the door chamber  312  may be located in front of the second machine compartment  16  in the cabinet chamber  12 . 
     The reason why the first machine compartment  13  is located in a rear region in the cabinet chamber  12  is to provide a balance against the weight of the door  3 . That is, when the door  3  is pulled forward to open the cabinet inlet  121 , there is a risk of the laundry treating apparatus  100  falling over due to the weight of the door  3 . Therefore, in order to prevent this problem, it may be preferable for the first machine compartment  13  to be located in a rear region in the cabinet chamber  12 . 
     The height of the door chamber  312  may be greater than the height of the region in which the first bottom surface  1251  is located among the regions in the cabinet chamber  12 . The reason for this is to allow laundry longer than laundry that can be received in the cabinet chamber  12  to be received in the door chamber  312 . 
     If the height of the door chamber  312  is less than the height of the region in which the first bottom surface  1251  is located among the regions in the cabinet chamber  12  and the door chamber  312  takes the form of an auxiliary box that is provided in a portion of the door  3  so as to intrude toward the cabinet chamber  12 , laundry that can be received in the cabinet chamber  12  may not be received in the auxiliary box. In addition, because the auxiliary box intrudes into the cabinet chamber  12 , the auxiliary box may hinder circulation of air through a first supply unit  14 , which will be described below. Therefore, it may be preferable that the door chamber  312  be provided in the door  3  and that the rear surface of the door  3  be of a flat surface form. In addition, in order to use the inner space in the door  3  to the maximum extent, the length of the door chamber  312  may be greater than the height of the region in which the first bottom surface  1251  is located among the regions in the cabinet chamber  12 . 
     The supply units  14  and  15  are provided to supply at least one of air or moisture to the cabinet chamber  12 .  FIG.  2    illustrates a configuration in which the supply units include a first supply unit  14  (or first supply device) for supplying air to the cabinet chamber  12  and a second supply unit  15  (or second supply device) for supplying moisture to the cabinet chamber  12 . 
     The first supply unit  14  may be configured to supply heated air (hot air) to the cabinet chamber  12 . Alternatively, the first supply unit  14  may be configured to supply non-heated air to the cabinet chamber  12 .  FIG.  2    shows the configuration of the former by way of example. 
     The second supply unit  15  may be configured to supply heated steam or non-heated steam (mist or the like) to the cabinet chamber  12 .  FIG.  2    shows the configuration of the second supply unit  15  for supplying heated steam to the cabinet chamber  12  by way of example. 
     The main body  1  may have an air suction hole  111   a , an air supply hole  111   b , and a moisture supply hole  111   c  formed through the first partition wall  111  to allow the cabinet chamber  12  and the first machine compartment  13  to communicate with each other therethrough. 
     In this example, the first supply unit  14  may include a duct  141  that is located between the air suction hole  111   a  and the air supply hole  111   b  so as to be connected thereto to form an air flow path, a duct fan  142  that causes air to move through the duct  141 , and a heat-exchanging unit (a first heat-exchanging unit/device), that sequentially dehumidifies and heats the air introduced into the duct  141 . 
     The first heat-exchanging unit (or a cabinet heat-exchanging unit  143 ,  144 ,  145 ,  146 , and  147 ) includes a heat absorber  143  that absorbs heat from the air introduced into the duct  141  to condense the air, and a heat generator  144  that supplies heat to the air that has passed through the heat absorber to heat the air. The heat absorber  143  and the heat generator  144  may be connected to each other via a refrigerant pipe  147  that forms a refrigerant circulation path. A compressor  145  that causes refrigerant to move through the refrigerant pipe, and a pressure regulator  146  that regulates the pressure of the refrigerant circulating through the refrigerant pipe, are provided in the refrigerant pipe  147 . 
     The second supply unit  15  may include a reservoir  151  that is provided in the first machine compartment  13  to store water therein, a steam heater  152  that is provided in the reservoir to heat water, and a supply pipe  153  that guides steam in the reservoir  151  to the moisture supply hole  111   c . The steam heater  152  may be embodied as an electric resistor (a heating element) that generates heat upon receiving power. 
     The second supply unit  15  receives water from a water supply tank  112 , and condensed water discharged from the heat absorber  143  is stored in a water drain tank  115 . 
     Referring to  FIGS.  1  and  2   , the water supply tank  112  and the water drain tank  115  may be placed into or removed from the first machine compartment  13  through the front surface of the first machine compartment  13 . That is, the water supply tank  112  may be formed as a drawer type, and may be inserted into the first machine compartment  13  to be connected to a water supply path  113 , which will be described below. In addition, the water drain tank  115  may also be formed as a drawer type, and may be inserted into the first machine compartment  13  to be connected to a water drain path  116 , which will be described later. 
     The water supply tank  112  may be connected to the reservoir  151  via the water supply path  113 , and a water supply valve  114  may be provided in the water supply path  113 . The water drain tank  115  may be connected to the duct  141  via the water drain path  116 , and condensed water stored in the duct  141  may move to the water drain tank  115  through a pump  117 . 
     A hanger controller for supporting a hanger H (or a cabinet hanger) may be provided in the cabinet chamber  12 . 
     The cabinet hanger H may include a laundry support portion H 1  for supporting laundry and a fastening hook H 2  fixed to the laundry support portion.

     The first body  171  may be formed in the shape of a bar that extends in a depth direction of the cabinet chamber  12  (i.e., the X-axis direction). The first body  171  may be connected to the second partition wall  118  via a first connection body  172  and a second connection body  173 . That is, the first connection body  172  may connect one end of the first body  171  to the second partition wall  118 , and the second connection body  173  may connect the other end of the first body  171  to the second partition wall  118 . 
     The first connection body  172  and the second connection body  173  may be made of an elastic material, such as rubber, so that the first body  171  moves in the depth direction of the cabinet chamber  12  (i.e., the X-axis direction) when the driving unit  18  operates. 
     The second body  174  may be coupled to the first body  171  via a body guide  176  and  177 . The body guide may include a rail  176  that is fixed to the first body  171 , and a block  177  that is fixed to the second body  174 . The block  177  is coupled to the rail  176  so as to be movable along the rail  176 . Accordingly, as shown in  FIG.  4   , the second body  174  may be moved out of the cabinet chamber  12  by the body guide (including the rail  176  and/or the block  177 ). Since the second body  174  is movable out of the cabinet chamber  12 , it is convenient to suspend the cabinet hanger H from the second body  174  or to remove the cabinet hanger H from the second body  174 . 
     Similar to the first body  171 , the second body  174  may be formed in the shape of a bar that extends in the depth direction of the cabinet chamber  12  (i.e., the X-axis direction), and may have a hook receiving recess  175  formed in the upper surface thereof to receive the fastening hook H 2  therein. 
     When the first body  171  and the second body  174  are disposed in the depth direction of the cabinet chamber  12 , the air supply hole  111   b  formed in the first partition wall  111  may be embodied as a slit that extends in the depth direction of the cabinet chamber  12 . The reason for this is to supply air to a relatively wide surface of the laundry. For the same reason, each of the air suction hole  111   a  and the moisture supply hole  111   c  may also be embodied as a slit that extends in the depth direction of the cabinet chamber  12 . 
     Referring to  FIG.  2   , the air suction hole  111   a  and the air supply hole  111   b  may be disposed in the width direction of the cabinet  11 . Meanwhile, the direction in which the hanger support unit  17  extends, specifically the direction in which the first body  171  or the second body  172  extends, may be the forward-backward direction or the depth direction of the cabinet  11 . 
     Accordingly, the air discharged from the air supply hole  111   b , which extends in the forward-backward direction of the cabinet  11 , may be uniformly supplied to gaps between the laundry articles suspended from the hanger support unit  17 . 
     Additionally, circulation of air in the cabinet chamber  12  is less likely to be disturbed by the laundry suspended from the hanger support unit  17 . 
     As shown in  FIG.  3   , the driving unit  18  may include a driving module  18   a  fixedly mounted in the second machine compartment  16 , a driven module  18   b  connected to the driving module  18   a  via a belt  18   c , and a converting module  18   d  for transmitting the rotational movement of the driven module  18   b  to the first body  171 . 
     As shown in  FIG.  4   , the driving module  18   a  may include a motor  181  fixedly mounted in the second machine compartment  16  and a driving pulley  182  fixed to the rotary shaft  183  (or the motor shaft) of the motor. 
     The driven module  18   b  may include a rotary shaft  185  that is disposed so as to pass through the second partition wall  118 , a driven pulley  184  that is located in the second machine compartment  16  to be fixed to one end of the rotary shaft, and an arm  187  that is located in the cabinet chamber  12  to be fixed to the other end of the rotary shaft. In order to support the rotary shaft  185 , a shaft support member  186  (or a bearing housing) may be disposed on the second partition wall  118 . 
     The driving pulley  182  and the driven pulley  184  are connected to each other via the belt  18   c . However, when the driving pulley is replaced with a driving gear fixed to the motor shaft  183  and the driven pulley is replaced with a driven gear fixed to the rotary shaft  185  and engaged with the driving gear, the belt may be omitted. 
     The converting module  18   d  may include a guide member  189  that takes the form of a recess or a slot formed in the first body  171 , and a guide-member coupling portion  188  that is provided at the free end of the arm  187  to be inserted into the guide member  189 . 
     The guide member  189  may extend in the width direction of the cabinet chamber  12  (i.e., the Y-axis direction or the direction perpendicular to the first body) (the guide member may extend in the depth direction of the cabinet chamber  12 ). The length of the guide member  189  may be set to be greater than or equal to the diameter of the rotation track formed by the guide-member coupling portion  188 . In this example, when the driving unit  18  operates, the first body  171 , the second body  174 , and the cabinet hanger H may perform reciprocating movement in the depth direction of the cabinet chamber  12  (i.e., the X-axis direction). However, movement thereof in the width direction of the cabinet chamber  12  may be regulated. That is, the circular movement of the driving unit  18  may be converted into reciprocating movement of the hanger support unit  17  in the forward-backward direction or the depth direction of the cabinet chamber  12 . 
     If the second body  174  is not fixed to the first body  171 , there is a risk of the second body  174  being damaged due to collision with the cabinet  11  or the door  13  when the hanger support unit  17  performs reciprocating movement in the forward-backward direction of the cabinet  11 . In order to prevent this problem, the hanger support unit  17  may include a stopper  178  for securing the second body  174  to the first body  171 . 
       FIGS.  3  and  4    illustrate an example in which the second body  174  is provided with a protrusion receiving portion  179  that is coupled to the stopper  178 . The stopper  178  may include a motor and a protrusion that is inserted into the protrusion receiving portion  179  or is separated from and moved away from the protrusion receiving portion  179  by the motor. The protrusion receiving portion  179  may be formed in the shape of a recess that receives the protrusion therein. 
     The user may hang the hanger in the hook receiving recess  175  after drawing the second body  174  forward, and then may move the second body  174  backwards to the original position thereof using the body guide  176  and  177 . Thereafter, the user may close the door  3 . In this example, a controller may detect closing of the cabinet chamber  12 , and may control the stopper  178  such that the protrusion moves into the protrusion receiving portion  179 , thereby fixing the second body  174 . Upon detecting opening of the door  3 , the controller may perform control such that the protrusion is separated from the protrusion receiving portion  179 , whereby the second body  174  may enter a state in which the second body  174  can be drawn forward. 
       FIG.  4    shows a state in which the second body  174  is drawn forward. The enlarged cross-sectional view in the lower side in  FIG.  4    shows a state in which the first body  171  and the second body  174  are coupled to each other by the stopper  178  when the cabinet chamber  12  is closed by the door  3 . 
     As shown in  FIG.  1   , the cabinet chamber  12  is opened or closed by the door  3 . 
     The door  3  may include a first door  31  that is secured to the cabinet  11  by means of a first hinge  35  to open or close the cabinet inlet  121 , and a second door  34  that is secured to the first door  31  by means of a second hinge  36  to open or close the door chamber  312  provided in the first door. 
     As shown in  FIG.  5   , when the first door  31  is opened, the first hinge  35  may enable the first door  31  to perform a combination of a first motion MA, in which the first door  31  moves in the forward direction of the cabinet  11  (i.e., the X-axis direction), and a second motion MB, in which the first door  31  moves in the width direction of the cabinet  11  (i.e., the Y-axis direction). 
     The reason why the first hinge  35  is configured to enable the first door  31  to perform a combination of the first motion MA and the second motion MB is to prepare for an example in which another object (e.g., a closet or another electronic apparatus) is located beside the main body  1 . Performing a combination of the first motion MA and the second motion MB may mean independently and sequentially performing the first motion MA and the second motion MB, or may mean simultaneously performing the first motion MA and the second motion MB. As shown in  FIG.  5   , when the cabinet inlet  121  is opened or closed, the first door  31  may move along a curved track created by the combination of the first motion MA and the second motion MB. However, while the door  3  is moving, the door  3  may face the cabinet inlet  121 . That is, the front surface of the door  3  is always oriented forwards while the door  3  is moving. The reason for this is to enable the user to easily access an interface, which is provided on the front surface of the second door  34 , to drive the door chamber  312  even when the cabinet chamber  12  is in an open state. 
     If the first door  31  is configured to rotate, a space allowing rotation of an edge of the first door is necessary near the side surface of the cabinet  11 . Therefore, if the first door  31  is not configured to perform the first motion MA and the second motion MB, a space needs to be secured between the side surface of the cabinet  11  and the side surface of another object, which is disadvantageous in terms of efficiency of use of indoor space or interior design. 
     The motion (the combination of the first motion and the second motion) of the first door  31  may be realized by the first hinge  35  having the structure shown in  FIG.  5   . The first hinge  35  may include a first fixed body  351  that is secured to the cabinet  11 , a second fixed body  352  that is secured to the first door  31 , a first connection bar  353  (or a first-hinge first connection bar) that interconnects the first fixed body and the second fixed body, and a second connection bar  354  (or a first-hinge second connection bar) that interconnects the first fixed body and the second fixed body. 
     The second hinge  36  may be formed to have the same structure as the first hinge  35 , or may be formed to have a different structure from the first hinge  35 . 
       FIG.  1    illustrates an example in which the second hinge  36  includes a first door fixed body  361  that is secured to the first door  31 , a second door fixed body  362  that is secured to the second door  34 , a first connection bar  363  (or a second-hinge first connection bar) that interconnects the two fixed bodies  361  and  362 , and a second connection bar  364  (or a second-hinge second connection bar) that interconnects the two fixed bodies  361  and  362 . 
     As shown in  FIG.  6   , the first door  31  includes a first door body  311 , in which the door chamber  312  is provided. The door chamber  312  may be provided as a space defined by one surface of the first door body  311  (i.e., the front surface of the first door body) being bent toward the interior of the cabinet chamber  12  (i.e., a space defined by the front surface of the first door body protruding toward the interior of the cabinet chamber). 
     That is, the door chamber  312  may be provided in the first door body  311  as a space for treating or exhibiting the laundry present in the cabinet chamber  12 . When the cabinet inlet  121  is closed by the first door  31 , the door chamber  312  is located in the cabinet chamber  12 . The reason for this is to minimize not only heat loss from the cabinet chamber  12  through the door  3  but also heat loss from the door chamber  312 . 
     The door chamber  312  may be formed in any of various shapes.  FIG.  6    illustrates an example in which the door chamber  312  is formed in a hexahedral shape. In this example, the door chamber  312  may be defined by a door-chamber top surface  314 , a door-chamber bottom surface  315 , a door-chamber mounting surface  316 , and two door-chamber side surfaces, and may have a door inlet  313  formed through one surface of the door chamber  312 . 
       FIG.  6    illustrates an example in which the door inlet  313  is formed through the front surface of the first door body  311 . In this example, the door-chamber mounting surface  316  interconnects the rear end of the door-chamber top surface  314 , the rear end of the door-chamber bottom surface  315 , and the rear ends of the two door-chamber side surfaces, and is disposed so as to face the door inlet  313 . 
     The first door body  311  may have a first device chamber  317  and a second device chamber  318  formed therein. 
     The first device chamber  317  may be located below the door chamber  312 , and the second device chamber  318  may be located above the door chamber  312 .  FIG.  6    illustrates an example in which the first device chamber  317  is isolated from the door chamber  312  by the door-chamber bottom surface  315 , and the second device chamber  318  is isolated from the door chamber  312  by the door-chamber top surface  314 . 
     The second door  34  may include a second door body  341  that is connected to the first door body  311  via the second hinge  36 , and a transparent body  342  that is provided at the second door body  341 . 
     The transparent body  342  is a component that enables the user to check the door chamber  312  from the outside. The second door body  341  may have a door through-hole formed therein in a shape corresponding to the edge of the door inlet  313 , and the transparent body  342  may be secured to the second door body  341  to block the door through-hole, and may be embodied as transparent glass or transparent plastic. 
     The transparent body  342  may be made of a material that allows visible light to pass therethrough. That is, the material of the transparent body  342  may be a translucent material, rather than a transparent material, so long as the user is capable of checking laundry or an item accommodated in the door chamber  312  through the transparent body from the outside. 
     A support body mounting portion  39 , by which the hanger  5  as well as the cabinet hanger H is supported, may be provided on the door-chamber mounting surface  316 . 
     As shown in  FIG.  1   , a shelf  32  that defines a space in which laundry, a bag, and/or an accessory is supported, may be provided on the door-chamber mounting surface  316 . 
     It is preferable for the shelf  32  to be detachably mounted on the door-chamber mounting surface  316 . This may prevent laundry from interfering with the shelf  32  when the hanger  5  is hung on the support body mounting portion  39 . A shelf support portion  316   a , to which the shelf  32  is detachably secured, may be provided on the door-chamber mounting surface  316 . The shelf support portion  316   a  may be formed as a slot-type recess that extends in the width direction of the door chamber  312  (i.e., the Y-axis direction). 
     As shown in  FIG.  6   , the first door body  311  may be provided with a sealing portion  33  that surrounds the door inlet  313 . The sealing portion  33  serves to prevent air or moisture in the door chamber  312  from being discharged outside through the space between the first door body  311  and the second door body  341  when the door inlet  313  is blocked by the second door  34 . In addition, the sealing portion  33  may also serve to maintain an interval between the front surface of the first door body  311  (i.e., the surface in which the door inlet is formed) and the second door body  341 . 
     A second heat-exchanging unit  37  (or a second heat-exchanger) is provided in at least one of the first device chamber  317  or the second device chamber  318 . 
     The second heat-exchanging unit  37  serves to supply air (heated air or non-heated air) to the door chamber  312 .  FIG.  6    illustrates an example in which the second heat-exchanging unit  37  is provided in each of the first device chamber  317  and the second device chamber  318 . 
     The second heat-exchanging unit  37  may include a first flow path  371  that is provided in the first device chamber  317 , a heat exchanger  372  (i.e., a second heat-exchanging unit) that sequentially dehumidifies and heats the air introduced into the first flow path, a first fan  375  that causes air to move through the first flow path, a second flow path  376  that is provided in the second device chamber  318 , and a second fan  377  that causes air to move through the second flow path. 
     A lower inflow hole  315   a  and a lower outflow hole  315   b , through which the door chamber  312  and the first device chamber  317  communicate with each other, may be formed in the door-chamber bottom surface  315 . 
     In this example, the first flow path  371  may include an air intake duct  371   a  connected to the lower inflow hole  315   a , an air exhaust duct  371   b  connected to the lower outflow hole  315   b , and a connection duct  371   c  interconnecting the two ducts  371   a  and  371   b . The first fan  375  may be located in the connection duct  371   c.    
     The heat exchanger  372  may be embodied as a thermoelectric device or a thermoelectric module. The thermoelectric device or the thermoelectric module is a device or a module using the Peltier effect, which is the phenomenon whereby, when current is passed through a circuit consisting of two different metals, a temperature difference is observed at the junctions between the two different metals. When embodied as a thermoelectric device, the heat exchanger  372  is provided with a heat absorption fin  373  that is provided in the air intake duct  371   a  to cool air, and a heat radiation fin  374  that is provided in the air exhaust duct  371   b  to heat air. 
     An upper outflow hole  314   b , through which the door chamber  312  and the second device chamber  318  communicate with each other, may be formed in the door-chamber top surface  314 , and an upper inflow hole  314   a  that communicates with the second device chamber  318 , may be formed in the front surface of the first door body  311  (i.e., the surface facing the second door body or the surface in which the door inlet is formed). Unlike what is shown in  FIG.  6   , the upper inflow hole  314   a  may be formed in the door-chamber top surface  314 . 
     When the upper inflow hole  314   a  is formed in the front surface of the first door body  311 , it is preferable for the sealing portion  33  to be formed in the shape of a ring that surrounds the door inlet  313  and the upper inflow hole  314   a.    
     The second flow path  376  may be embodied as a duct that interconnects the upper inflow hole  314   a  and the upper outflow hole  314   b . The second fan  377  may be provided in the second flow path  376 , and a heating unit  378  (i.e., a third heat-exchanging unit) that heats the air that has passed through the second fan  377 , may be further provided in the second flow path  376 . 
     When the first fan  375  operates, the air in the door chamber  312  is introduced into the air intake duct  371   a  through the lower inflow hole  315   a . The air introduced into the air intake duct is condensed while flowing through the heat absorption fin  373 , and the dehumidified air is heated while flowing through the heat radiation fin  374 . The heated air is re-supplied to the door chamber  312  through the air exhaust duct  371   b  and the lower outflow hole  315   b . Accordingly, the laundry treating apparatus  100  may dry laundry or an accessory accommodated in the door chamber  312 , and may maintain constant humidity. 
     The second fan  377  and the heating unit  378  may operate during operation of the first fan  375  and the heat exchanger  372 . Accordingly, when the number of laundry articles or accessories accommodated in the door chamber  312  is large, it is possible to dry the same and/or to control humidity in a short time. 
     When the second fan  377  operates, the air in the door chamber  312  may move along the second flow path  376 , and the air moving along the second flow path may be heated while flowing through the heating unit  378 . 
     The upper outflow hole  314   b  may be located above the support body mounting portion  39  so that the air discharged from the second flow path  376  is directly supplied to the laundry hung on the hanger  5 . 
       FIG.  7    shows an example of the hanger  5  that is mountable in the door chamber  312  or the cabinet chamber  12 . As shown in  FIG.  7   , the hanger  5  may include a hook-shaped fastening unit  52  (or hook-shaped fastener). 
     Therefore, the hanger  5  may be hung on a hanging bar irrespective of the laundry treating apparatus  100 . The hanger  5  may be removably mounted in the laundry treating apparatus  100 . The hanger  5  may be hung on the hanger support unit  17 , more specifically in the hook receiving recess  175 , or may be hung on the support body mounting portion  39  (refer to  FIG.  14   ) provided in the door chamber  312 . 
     Compared to the above-described cabinet hanger H, the hanger  5  is characterized by including at least one of an air supply unit  53  (see  FIG.  8    for example) for supplying air to laundry or a moisture supply unit  55  (see  FIG.  8    for example) for supplying moisture to laundry. Therefore, the hanger  5  may independently manage laundry hung on the hanger  5  separately from the laundry treating apparatus  100 . The air supply unit  53  is a structural device, and may be referred to as an air supply device. The moisture supply unit  55  is a structural device, and may be referred to as a moisture supply device. 
     The hanger  5  may not only be used in the cabinet chamber  12  or the door chamber  312  of the laundry treating apparatus  100 , but may also be independently used in any of places in which a general hanger can be placed, for example in a closet or in a place in which a hanging bar or a hanging hook is provided, irrespective of the laundry treating apparatus  100 . 
     When the hanger  5  is used in the cabinet chamber  12 , the hanger  5  may be hung on the hanger support unit  17 . Alternatively, the hanger  5  may be hung on any one of the left side surface, the right side surface, and the rear surface of the cabinet chamber  12 . 
     It may also be possible to manage laundry using the hanger  5  in a limited space not allowing mounting of the first machine compartment  13  accommodating devices for supplying hot air and moisture. That is, when it is difficult to mount a device for spraying hot air and/or steam (or moisture) due to a limitation in the space in which laundry is accommodated, only the hanger  5  may be independently used to manage laundry hung thereon by supplying hot air and/or steam (or moisture) to the laundry. 
     Referring to  FIG.  7   , the hanger  5  may include a support body  51  for supporting laundry and a fastening unit  52  for securing the support body  51  to the support body mounting portion  39  provided in the door chamber  312 . The fastening unit  52  is structural and may be referred to as a fastener and/or a fastening device. 
     Additionally, the hanger  5  may include spacers  6   a  and  6   b , which are formed at the upper portion of the support body  51  and are spaced apart from each other, with the fastening unit  52  interposed therebetween, in order to support the laundry such that the laundry is spaced apart from the support body  51 . 
     The support body  51  may further include an air intake hole  514   a  for suctioning external air into the support body  51  and an air exhaust hole  517  for discharging the suctioned air. The support body  51  may include a supply tank  558  for supplying moisture. 
     The air intake hole  514   a  may be located above the supply tank  558  so as to overlap the supply tank  558  in the height direction of the hanger  5 . This structure may be made in consideration of the weight balance of the hanger  5 . For the same reason, the fastening unit  52  may be located so as to overlap the air intake hole  514   a  in the height direction of the hanger  5 . 
     The air intake hole  514   a  may be located at an upper portion of the support body  51 . This may prevent the laundry hung on the support body  51  from blocking the air intake hole  514   a  and thus disturbing suction of external air through the air intake hole  514   a.    
     The air exhaust hole  517  may be provided in plural, and the plurality of air exhaust holes  517  may be formed in each of the top surface, the left and right side surfaces, and a body bottom surface  516  of the support body  51  that forms the bottom surface of the support body  51 . This may discharge air suctioned through the air intake hole  514   a  to various parts of the laundry hung on the hanger  5 . This may maximally uniformly distribute air over the laundry. 
     A plurality of discharge holes  518  may be formed in each of the top surface, the left and right side surfaces, and the body bottom surface  516  of the support body in order to supply moisture or steam from the supply tank  558  to the laundry. The air exhaust holes  517  and the discharge holes  518  may be disposed to be parallel to each other. When the direction in which the air intake hole  514   a  is open is defined as a forward direction, the air exhaust holes  517  may be located behind the discharge holes  518 . 
     The size of each of the air exhaust holes  517  may be larger than the size of each of the discharge holes  518 . Considering the sizes of the particles of moisture and air, it may be preferable that the size of each of the discharge holes  518  be smaller than the size of each of the air exhaust holes  517  in order to spray moisture. 
     When the hanger  5  is coupled to the support body mounting portion  39  located on the door-chamber mounting surface  316 , if the discharge holes  518  are located close to the door-chamber mounting surface  316 , a relatively large amount of condensed water may be generated. Due to the above-described disposition of the discharge holes  518  and the air exhaust holes  517 , generation of condensed water may be maximally prevented. That is, it is preferable for the discharge holes  518  to be located farther away from the door-chamber mounting surface  316  than the air exhaust holes  517 . 
     The support body  51  is formed such that the left and right portions thereof are curved forwards from the central portion thereof. That is, the support body  51  is formed in the shape of a bow (i.e., the two opposite side portions are bent forwards). The reason why the support body  51  is formed in the shape of a curved surface that is convex backwards is not only to match the shape or the design of the laundry hung on the hanger  5 , but also to allow the discharge holes to be located as far away from the door-chamber mounting surface  316  as possible. 
       FIG.  8    is an exploded perspective view of an example of the hanger  5 . 
     The hanger  5  may include a support body  51  for supporting laundry and a fastening unit  52  coupled to the upper side of the support body  51  to allow the support body to be hung on the support body mounting portion  39 . The fastening unit  52  may include a hanger hook. 
     The hanger  5  may include spacers  6   a  and  6   b  that are formed at the upper portion of the support body  51  and are spaced apart from each other, with the fastening unit  52  interposed therebetween. 
     Additionally, the hanger  5  may include an air supply unit  53  that is provided in (or at) the support body  51  to supply air to laundry supported by the support body  51 , and a moisture supply unit  55  that is provided in (or at) the support body  51  to supply moisture or steam to the laundry. The air supply unit  53  is a structural device and may also be referred to as an air supply device. 
     The hanger  5  may include a supply tank  558  that is mounted on one surface of the support body  51  to supply water that is to be used for supply of moisture or steam to the laundry. 
     Referring to  FIG.  8   , the support body  51  may be bilaterally symmetrical with respect to the fastening unit  52 . The spacers  6   a  and  6   b  may be formed to be symmetrical with each other. The reason for this is that clothes are generally formed to be bilaterally symmetrical. 
       FIG.  9    is an exploded perspective view showing the support body  51  and the spacers  6   a  and  6   b  among the components of the hanger  5  shown in  FIG.  8   . 
     The support body  51  may include a base  513 , to which the fastening unit  52  is secured, a first support surface  511  that extends from one side of the base  513  to support laundry and has a space defined therein, a second support surface  512  that extends from the other side of the base  513  to support laundry and has a space defined therein, and a connection surface  514  that connects the base  513  to the support surfaces  511  and  512 . 
     The first support surface  511  and the second support surface  512  may be located at positions symmetrical with each other with respect to the base  513 . The reason for this is that clothes have a substantially bilaterally symmetrical shape. 
     The first support surface  511  may be formed as a downwardly slanted surface that extends from a first boundary P 1  that is located at the left end of the base  513 , and the second support surface  512  may be formed as a downwardly slanted surface that extends from a second boundary P 2  that is located at the right end of the base  513 . The connection surface  514  may include a first connection surface  5141  that faces the front surface of the laundry, and a second connection surface  5142  that faces the rear surface of the laundry. 
     The reason why the first support surface  511  and the second support surface  512  are formed as slanted surfaces is to allow laundry to be hung thereon regardless of size. That is, various sizes of laundry articles, e.g. children&#39;s clothes or adults&#39; clothes, may be hung on the hanger  5 . If the support body has a rectangular shape, and the first support surface and the second support surface are formed as horizontal surfaces having sizes suitable for adults&#39; clothes, rather than slanted surfaces, it is difficult to hang children&#39;s clothes, which are smaller than adults&#39; clothes, on the hanger  5 . On the other hand, if the first support surface and the second support surface are formed as horizontal surfaces having sizes suitable for children&#39;s clothes, it is not possible to hang adults&#39; clothes on the hanger  5 . Therefore, the first support surface  511  and the second support surface  512  are formed as slanted surfaces so that various sizes of laundry articles are stably supported by the hanger  5  in a symmetrical shape. That is, depending on the type or size of laundry hung on the hanger  5 , the parts of the laundry that are hung on the first support surface  511  and the second support surface  512  may vary. 
     The support body  51  may be provided with the body bottom surface  516 . The body bottom surface  516  may be a bottom surface that interconnects the free end of the first support surface  511 , the free end of the second support surface  512 , and the free ends of the two connection surfaces  5141  and  5142 . 
     As shown in  FIG.  9   , the connection surface  514  may have an air intake hole  514   a  formed therein to suction air into the support body  51 . The air intake hole  514   a  may be formed in any one of the first connection surface  5141  that faces the front surface of the laundry, and the second connection surface  5142  that faces the rear surface of the laundry. In an example in which the hanger  5  is used alone, the air intake hole  514   a  may be formed in any one of the first connection surface  5141  and the second connection surface  5142 . However, considering that the hanger  5  is hung on the door-chamber mounting surface  316 , it may be preferable for the air intake hole  514   a  to be formed in the first connection surface  5141 . 
     It is preferable for the air intake hole  514   a  to be located at a position that is not covered by the laundry. The air intake hole  514   a  is formed in the upper portion of the support body  51  in order to facilitate suction of external air. Therefore, it may be preferable for the air intake hole  514   a  to be located closer to the fastening unit  52  than to the body bottom surface  516 . 
     As shown in  FIG.  9   , each of the first support surface  511  and the second support surface  512  may have formed therein air exhaust holes  517 , through which air is discharged, and discharge holes  518 , through which moisture is discharged. 
     As shown in  FIG.  9   , the first support surface  511  may include a first top surface  511   a  that is secured to the base  513  to support the upper part or one of the left part and the right part of the laundry, and a first side surface  511   b  that extends from the first top surface  511   a  so as to be located at a position corresponding to one of the sleeves of the laundry. The second support surface  512  may include a second top surface  512   a  that is secured to the base  513  to support the upper part or the other of the left part and the right part of the laundry, and a second side surface  512   b  that extends from the second top surface  512   a  so as to be located at a position corresponding to the other of the sleeves of the laundry. 
     The reason why the first top surface  511   a  and the second top surface  512   a  are formed so as to be slanted is to allow laundry to be hung thereon regardless of size. The first side surface  511   b  and the second side surface  512   b  may respectively extend from the first top surface  511   a  and the second top surface  512   a  at different angles from the first top surface  511   a  and the second top surface  512   a.    
     As shown in  FIG.  9   , the first side surface  511   b  and the second side surface  512   b  may extend vertically, or may be slanted more steeply than the first top surface  511   a  and the second top surface  512   a , respectively. The reason for this is to remove wrinkles from the laundry hung on the hanger  5  by applying as much tension as possible to the part of the laundry other than the parts thereof supported by the first top surface  511   a  and the second top surface  512   a , using the weight of the laundry. 
     Additionally, in order to supply air and/or moisture (steam) to as large an area as possible of the part of the laundry hung on the hanger  5 , which is not supported by the first top surface  511   a  or the second top surface  512   a , it may be preferable for the first side surface  511   b  and the second side surface  512   b  to extend vertically or to be slanted in different directions from the first top surface  511   a  and the second top surface  512   a , respectively. 
     The air exhaust hole  517  may include at least one of a first air exhaust hole  517   a  formed in each of the first top surface  511   a  and the second top surface  512   a , a second air exhaust hole  517   b  formed in each of the first side surface  511   b  and the second side surface  512   b , and/or a third air exhaust hole  517   c  formed through the body bottom surface  516 . 
     The discharge hole  518  may include at least one of a first discharge hole  518   a  formed in each of the first top surface  511   a  and the second top surface  512   a , a second discharge hole  518   b  formed in each of the first side surface  511   b  and the second side surface  512   b , and/or a third discharge hole  518   c  formed through the body bottom surface  516 .  FIG.  9    illustrates an example in which the air exhaust hole  517  includes all of the first air exhaust hole  517   a , the second air exhaust hole  517   b , and the third air exhaust hole  517   c , and the discharge hole  518  includes all of the first discharge hole  518   a , the second discharge hole  518   b , and the third discharge hole  518   c.    
     Meanwhile, each of the first connection surface  5141  and the second connection surface  5142  may be formed such that the left and right portions thereof are curved gently in the forward direction of the hanger  5 . The reason for this is to increase the rigidity of the support body  51 . Additionally, the reason for this is to allow the discharge holes  518  to be located far away from the door-chamber mounting surface  316 . 
     Meanwhile, referring to  FIGS.  7  to  9   , in order to minimize increase in resistance to flow of air or moisture due to blocking of the air exhaust holes  517  and the discharge holes  518  by the laundry hung on the support body  51 , the hanger  5  may include spacers  6   a  and  6   b  to allow the laundry to be spaced a predetermined interval apart from the support body  51 . 
     The spacers  6   a  and  6   b  may include a first spacer  6   a  that is secured to the support body  51  to maintain a predetermined interval between the laundry and the first support surface  511 , and a second spacer  6   b  that is secured to the support body  51  to maintain a predetermined interval between the laundry and the second support surface  512 . 
     The first spacer  6   a  may include a first seating body  61 , by which the laundry is supported, and a first fixed portion  62  that secures the first seating body  61  to the first support surface  511 . The second spacer  6   b  may include a second seating body  65 , by which the laundry is supported, and a second fixed portion  66  that secures the second seating body  65  to the second support surface  512 . 
     The first fixed portion  62  may be formed in the shape of a bar that secures the first seating body  61  to the first top surface  511   a , and the second fixed portion  66  may be formed in the shape of a bar that secures the second seating body  65  to the second top surface  512   a.    
     The first seating body  61  may have a first-seating-body through-hole  611  formed therein to allow fluid supplied from the first air exhaust holes  517   a  and the first discharge holes  518   a  formed in the first top surface  511   a  to pass therethrough. Similarly, the second seating body  65  may have a second-seating-body through-hole  651  formed therein to allow fluid supplied from the first air exhaust holes  517   a  and the first discharge holes  518   a  formed in the second top surface  512   a  to pass therethrough. 
     The first spacer  6   a  may include a first upper support portion  63  that connects the upper end of the first seating body  61  to the first support surface  511  to support a portion of the upper part of the laundry, and the second spacer  6   b  may include a second upper support portion  67  that connects the upper end of the second seating body  65  to the second support surface  512  to support another portion of the upper part of the laundry. 
     As described above, the air intake hole  514   a  is disposed at a position that is not covered by the laundry. The first upper support portion  63  and the second upper support portion  67  may be provided such that the air intake hole  514   a  is located between the first upper support portion  63  and the second upper support portion  67 . 
       FIG.  10    shows a supply tank  558  and a tank mounting portion  514   b  provided in the support body  51  to receive the supply tank  558 . 
     The supply tank  558  is secured to the support body  51  through the tank mounting portion  514   b  provided in (or at) the connection surface  514 . A drain hole  558   a  is formed in a bottom surface of the supply tank  558 . The opening of the drain hole  558   a  is controlled by the valve  558   b . The valve  558   b  may be embodied as a check valve. 
     A supply flow path  559  may be provide that includes an actuator  559   a  for operating the valve  558   b  to open the drain hole  558   a , a connection pipe  559   b  for connecting the actuator  559   a  to a moisture generator  556 , and a connection-pipe valve  559   c  for controlling opening and closing of the connection pipe  559   b.    
     As shown in  FIG.  10   , when the supply tank  558  is inserted into the tank mounting portion  514   b , the actuator  559   a  operates the valve  558   b  to open the drain hole  558   a . When the drain hole  558   a  is opened, the water in the supply tank  558  may flow into the connection pipe  559   b . When the connection-pipe valve  559   c  opens the connection pipe  559   b , the water may flow to the moisture generator  556 . 
     Referring to  FIG.  11   , the air supply unit  53  may include an air supply body  531  that has an air flow path  532  (see  FIG.  13 ( a )  for example) formed therein. The air supply body  531  may be formed in any of various shapes, so long as the same is capable of being inserted into the support body  51 . The air supply body  531  may be inserted into or taken out of the support body  51  in the state in which the body bottom surface  516  is separated from the support body  51 . 
     The air flow path  532  is a flow path that connects the air intake hole  514   a  to the air exhaust holes  517 . The air flow path  532  is connected to the air intake hole  514   a  via an air-intake-hole connection portion  533 , and is connected to the air exhaust holes  517  via air-exhaust-hole connection portions. That is, the air-exhaust-hole connection portions may be formed through the air supply body  531 , and may include a first air-exhaust-hole communication hole  534  that connects the air flow path  532  to the first air exhaust hole  517   a , a second air-exhaust-hole communication hole  535  that connects the air flow path  532  to the second air exhaust hole  517   b , and a third air-exhaust-hole communication hole  536  (see  FIG.  13 ( a )  for example) that connects the air flow path  532  to the third air exhaust hole  517   c.    
     The air supply body  531  may be provided therein with a fan  537  and a heater  538  (i.e., a first heater). 
     As shown in  FIG.  11   , the fan  537  serves to suction external air into the air flow path  532  through the air intake hole  514   a  and the air-intake-hole connection portion  533 . The fan  537  may include an impeller  537   a  that is located in the air-intake-hole connection portion  533 , and an impeller motor  537   b  that is secured to the air supply body or the support body to rotate the impeller. The impeller  537   a  may be disposed such that the center of rotation thereof is located at the center of the rotary shaft of the impeller motor  537   b  (i.e., the center of the air-intake-hole connection portion  533  or the center of the air intake hole  514   a ). 
     The heater  538  serves to heat air that has passed through the impeller  537   a . The heater  538  may be embodied as a C-shaped heating element (i.e., an electric resistor configured to convert electrical energy into thermal energy). The heater  538  may be formed in the shape of partly surrounding the circumferential surface of the impeller  537   a  (or the shape of partly surrounding the edge of the air-intake-hole connection portion), and the open portion of the C-shaped heater  538  may face the fastening unit  52  (or the uppermost end of the air supply body). 
     This may prevent the fastening unit  52  from being heated by the air heated by the heater  538 . When the fan  537  rotates, air may be suctioned through the air intake hole  514   a  in the rotation direction of the fan  537  (i.e. the forward-backward direction of the hanger  5 ), may be discharged through the side surface of the fan  537 , and may move to the air flow path  532 . This fan may be referred to as a sirocco fan. The air suctioned along the rotary shaft of the fan  537  or the rotary shaft of the motor  537   b  is discharged outside through the side surface of the fan, which is perpendicular to the rotary shaft thereof. 
     Therefore, the air intake hole  514   a  may be formed in one surface of the support body  51 , and the air exhaust holes  517  may be formed in another one or more of the surfaces of the support body  51 . 
     That is, the air intake hole  514   a  may be formed in the first connection surface  5141 , and the air exhaust holes  517  may be formed in the first top surface  511   a , the second top surface  512   a , the first side surface  511   b , the second side surface  512   b , and the body bottom surface  516 . 
     This is merely given by way of example, and any of various other fans may be used, so long as the same is capable of suctioning air through the air intake hole  514   a  and moving the air to the air flow path  532 . 
     The heater  538  may be located closer to the air intake hole  514   a  than to the air exhaust holes  517 . More specifically, the heater  538  may be adjacent to the fan  537  and may surround a portion of the fan  537 . The reason for this is not only to effectively heat air discharged from the fan  537  before the air is dispersed, but also to prevent overheating of the heater  538 . That is, the air discharged from the fan  537  receives heat from the heater  538 , thereby preventing the heater  538  from overheating and being damaged. 
     Referring to  FIG.  12   , the hanger  5  may include an air supply unit  53  that is provided in the support body  51  to supply air to laundry supported by the support body  51 , and a moisture supply unit  55  that is provided in the support body  51  to supply moisture or steam to the laundry. 
     The moisture supply unit  55  may include a moisture generator  556  that generates moisture or steam, a moisture supply body  551  that forms a moisture flow path  552  (see  FIG.  13 ( b )  for example) to discharge moisture or steam generated in the moisture generator  556  to the outside, a supply tank  558  (see  FIG.  8    for example) that supplies water to the moisture generator  556 , and a supply flow path  559  that supplies water from the supply tank  558  to the moisture generator. The remaining components of the moisture supply unit other than the supply tank  558  are illustrated in  FIG.  12   . 
     The air supply unit  53  may be located behind the moisture supply unit  55 . This may reduce moving paths of air and moisture (or steam) in consideration of the positions of the air exhaust holes  517  and the discharge holes  518 . The longer the moving paths, the greater the heat loss of air and moisture. More specifically, the moisture supply body  551  may be located in front of the air supply body  531 . 
     The height of the uppermost end of the moisture supply body  551  may be less than the height of the uppermost end of the air supply body  531 . This may enable connection between the air-intake-hole connection portion  533  that is located at the upper portion of the air supply body  531 , and the air intake hole  514   a.    
     Because the moisture generator  556 , the supply tank  558 , and the supply flow path  559  are located in the support body  51  (or at the support body  51 ), at least one of the air supply body  531  or the moisture supply body  551  may include an accommodating portion  56  that defines a space for accommodating the moisture generator  556 , the supply tank  558 , and the supply flow path  559 . 
       FIG.  12    illustrates an example in which the accommodating portion  56  includes a generator accommodating portion  562  that is provided in the moisture supply body  551  to define a space for accommodating the moisture generator  556 , and a tank accommodating portion  561  that is provided in the air supply body  531  to define a space for accommodating the supply tank  558 . 
     Referring to  FIGS.  10  and  12   , the generator accommodating portion  562  may be formed as a recess that is depressed in the bottom surface of the moisture supply body  551  toward the top surface of the moisture supply body  551 , and the tank accommodating portion  561  may be formed as a recess that is depressed in the bottom surface of the air supply body  531  toward the top surface of the air supply body  531 . 
     When the tank mounting portion  514   b  is located higher than the moisture generator  556  (water in the supply tank is supplied to the moisture generator without a pump), the height of the tank accommodating portion  561  needs to be set to be greater than the height of the generator accommodating portion  562 . 
     The tank mounting portion  514   b  provided in the connection surface  514  forms a passage that penetrates the connection surface  514  to be connected to the tank accommodating portion  561 , and the valve  558   b  of the supply tank  558  is coupled to the actuator  559   a  when the supply tank  558  is inserted into the accommodating portion  56  through the tank mounting portion  514   b.    
       FIGS.  10  and  12    illustrate an example in which the supply tank  558  is inserted into the tank accommodating portion  561  through the tank mounting portion  514   b.    
     When the generator accommodating portion  562  is provided, a moisture supply pipe  557  may be provided so as to supply moisture through two opposite side surfaces of the generator accommodating portion  562  (i.e., the left surface and the right surface of the generator accommodating portion that extend in the height direction of the support body). Accordingly, the amount of moisture supplied to the discharge holes  518  formed in the first support surface  511  and the amount of moisture supplied to the discharge holes  518  formed in the second support surface  512  may be similar to each other. 
     An air supply unit  53  that moves air (heated air or non-heated air) introduced into the air intake hole  514   a  to the air exhaust holes  517 , and a moisture supply unit  55  that generates moisture (heated steam or non-heated steam) and supplies the same to the discharge holes  518 . The air supply unit may be provided in (or at) the support body  51 . 
     Referring to  FIGS.  8  to  12   , the fan  537  may be located closer to the air intake hole  514   a  than to the air exhaust holes  517 . The reason for this is to more easily suction external air. Due to the characteristics of the support body  51 , in which the width thereof in the forward-backward direction is less than that in the width direction, and the sizes of the air exhaust holes  517 , the flow speed at which the air suctioned into the hanger, (i.e., the support body  51 ), is discharged naturally increases. Therefore, force required to suction external air may be greater than force required to discharge internal air. 
     The discharge holes  518  may be located closer to the air exhaust holes  517  than to the air intake hole  514   a . The reason for this is to prevent moisture discharged from the discharge holes  518  from being suctioned into the air intake hole  514   a.    
     The fan  537  may be located closer to the air intake hole  514   a  than to the air exhaust holes  517 . In addition, the fan  537  may be located closer to the air intake hole  514   a  than to the discharge holes  518 . 
     The air intake hole  517  may be located between the first support surface  511  and the second support surface  512  in order to maintain lateral balance of the support body  51 . For the same reason, the fan  537  may also be located between the first support surface  511  and the second support surface  512 . 
     As shown in  FIG.  13 ( a ) , the air supply unit  53  may include an air supply body  531  that has an air flow path  532  formed therein. The air supply body  531  may be formed in any of various shapes, so long as the same is capable of being inserted into the support body  51 . The air supply body  531  may be inserted into or taken out of the support body  51  in the state in which the body bottom surface  516  of the support body is separated from the support body  51 . 
     The air flow path  532  is a flow path that connects the air intake hole  514   a  to the air exhaust holes  517 . The air flow path  532  is connected to the air intake hole  514   a  via an air-intake-hole connection portion  533 , and is connected to the air exhaust holes  517  via air-exhaust-hole connection portions. The air-exhaust-hole connection portions may be formed through the air supply body  531 , and may include first air-exhaust-hole communication holes  534  connecting the air flow path  532  to the first air exhaust holes  517   a , second air-exhaust-hole communication holes  535  connecting the air flow path  532  to the second air exhaust holes  517   b , and third air-exhaust-hole communication holes  536  connecting the air flow path  532  to the third air exhaust holes  517   c.    
     A fan  537  and a heater  538  (i.e., a first heater) may be provided in the air supply body  531 . 
     As shown in  FIG.  8   , the fan  537  serves to suction external air into the air flow path  532  through the air intake hole  514   a  and the air-intake-hole connection portion  533 . The fan  537  may include an impeller  537   a  that is located in the air-intake-hole connection portion  533 , and an impeller motor  537   b  that is secured to the air supply body or the support body to rotate the impeller. The impeller  537   a  may be disposed such that the center of rotation thereof is located at the center of the air-intake-hole connection portion  533 . 
     The heater  538  serves to heat air that has passed through the impeller  537   a . The heater  538  may be embodied as a C-shaped heating element (i.e., an electric resistor configured to convert electrical energy into thermal energy). The heater  538  may be formed in the shape of surrounding (or partly surrounding) the circumferential surface of the impeller  537   a  (or the shape of surrounding the edge of the air-intake-hole connection portion), and the open portion of the C-shaped heater  538  may face the fastening unit  52  (or the uppermost end of the air supply body). 
     The moisture supply unit  55  may include a moisture supply body  551  that has a moisture flow path  552  formed therein. The moisture supply body  551  may be formed in any of various shapes, so long as the same is capable of being inserted into the support body  51 . The moisture supply body  551  may be inserted into or taken out of the support body  51  in the state in which the body bottom surface  516  of the support body is separated from the support body  51 . 
     As shown in  FIG.  13 ( b ) , the moisture flow path  552  is a flow path that supplies moisture generated in the moisture generator  556  to the discharge holes  518 . The moisture flow path  552  is provided with discharge-hole connection portions that are connected to the discharge holes  518 . 
     The discharge-hole connection portions may be formed through the moisture supply body  551 , and may include first discharge-hole communication holes  553  connecting the moisture flow path  552  to the first discharge holes  518   a , second discharge-hole communication holes  554  connecting the moisture flow path  552  to the second discharge holes  518   b , and third discharge-hole communication holes  555  connecting the moisture flow path  552  to the third discharge holes  518   c.    
     The moisture generator  556  may be embodied as a steam generator configured to generate (or provide) heated steam, or may be embodied as a mist generator configured to generate (or provide) non-heated steam (mist or the like).  FIG.  13 ( b )  illustrates an example in which the moisture generator  556  is embodied as a steam generator. 
     The moisture generator  556  shown in  FIG.  13 ( b )  may include a storage body  556   a  that has a space defined therein to store water and is located in the support body  51 , and a heater  556   b  (i.e., a second heater), that heats water in the storage body. 
     The moisture generator  556  may be connected to the moisture flow path  552  via a moisture supply pipe  557 , and a valve for controlling movement of moisture to the moisture flow path  552  may be provided in the moisture supply pipe  557 . 
     Referring to  FIGS.  8  and  13   , the moisture generator  556  receives water stored in the supply tank  558  through the supply flow path  559 . 
     The supply tank  558  may have a space defined therein to store water, and may be detachably secured to the support body  51 . The supply flow path  559  may guide the water stored in the supply tank  558  to the storage body  556   a.    
     The supply tank  558  is secured to the support body  51  through the tank mounting portion  514   b  provided in the connection surface  514 . A drain hole  558   a  is formed in the bottom surface of the supply tank  558 . The opening of the drain hole  558   a  is controlled by the valve  558   b . The valve  558   b  may be embodied as a check valve. 
     The supply flow path  559  may include an actuator  559   a  for operating the valve  558   b  to open the drain hole  558   a , a connection pipe  559   b  connecting the actuator  559   a  to the storage body  556   a  of the moisture generator, and a connection-pipe valve  559   c  controlling opening and closing of the connection pipe  559   b.    
     As shown in the drawings, when the supply tank  558  is inserted into the tank mounting portion  514   b , the actuator  559   a  operates the valve  558   b  to open the drain hole  558   a . When the drain hole  558   a  is opened, the water in the supply tank  558  may flow into the connection pipe  559   b . When the connection-pipe valve  559   c  opens the connection pipe  559   b , the water may flow to the storage body  556   a.    
     Because the moisture generator  556 , the supply tank  558 , and the supply flow path  559  are located in the support body  51  (or at the support body), at least one of the air supply body  531  or the moisture supply body  551  may include an accommodating portion  56  that defines a space for accommodating the moisture generator  556 , the supply tank  558 , and the supply flow path  559 . 
       FIG.  13 ( b )  illustrates an example in which the accommodating portion  56  includes a generator accommodating portion  562  that is provided in the moisture supply body  551  to define a space for accommodating the moisture generator  556 , and a tank accommodating portion  561  that is provided in the air supply body  531  to define a space for accommodating the supply tank  558 . 
     The generator accommodating portion  562  may be formed as a recess that is depressed in the bottom surface of the moisture supply body  551  toward the top surface of the moisture supply body  551 , and the tank accommodating portion  561  may be formed as a recess that is depressed in the bottom surface of the air supply body  531  toward the top surface of the air supply body  531 . 
     When the tank mounting portion  514   b  is located higher than the moisture generator  556  (i.e., water in the supply tank is supplied to the moisture generator without a pump), the height of the tank accommodating portion  561  needs to be set to be greater than the height of the generator accommodating portion  562 . 
     The tank mounting portion  514   b  provided in the connection surface  514  forms a passage that penetrates the connection surface  514  to be connected to the tank accommodating portion  561 , and the valve  558   b  of the supply tank  558  is coupled to the actuator  559   a  when the supply tank  558  is inserted into the tank accommodating portion  561  through the tank mounting portion  514   b.    
     When the generator accommodating portion  562  is provided, the moisture supply pipe  557  may be provided so as to supply moisture through two opposite side surfaces of the generator accommodating portion  562  (i.e., the left surface and the right surface of the generator accommodating portion that extend in the height direction of the storage body). Accordingly, the amount of moisture supplied to the discharge holes  518  formed in the first support surface  511  and the amount of moisture supplied to the discharge holes  518  formed in the second support surface  512  may be similar to each other. 
     Referring to  FIGS.  13  and  14   , the impeller motor  537   b , the heater  538  of the air supply unit, and the heater  556   b  of the moisture generator may receive power through a fastening-unit terminal  521  provided at the fastening unit  52 . 
     As described above, the support body mounting portion  39 , by which the hanger  5  as well as the cabinet hanger H is supported, may be provided on the door-chamber mounting surface  316 . When the fastening unit  52  is provided so as to be secured to the support body mounting portion  39  provided in the door chamber, the support body mounting portion  39  may be provided with a support-bar terminal  393  that connects the fastening-unit terminal  521  to a power supply. 
     The support body mounting portion  39  may include a support bar  391  that is secured to the door-chamber mounting surface  316 , and a mounting recess  392  that is formed in the support bar to allow the fastening unit  52  to be seated therein. The support-bar terminal  393  may be formed as a conductive element that is secured in the mounting recess  392  and is connected to the power supply, and the fastening-unit terminal  521  may be formed as a conductive element that is brought into contact with the support-bar terminal  393  when the fastening unit  52  is inserted into the mounting recess  392 . 
     In order to independently use the hanger  5  separately from the laundry treating apparatus  100 , a power connection line for supplying external power to the hanger  5  may be provided in the hanger  5  (or at the hanger  5 ). 
     The fastening unit  52  shown in  FIG.  14    is formed in the shape of a hook that is secured to the base  513 . Alternatively, the fastening unit  52  may be embodied as a fastening bar that protrudes from the base  513  toward the door-chamber mounting surface  316 . 
     Meanwhile, referring to  FIGS.  12  to  14   , the moisture generator  556  may be located below the supply tank  558  while being spaced a predetermined distance apart from the supply tank  558 . The reason for this is to prevent the water in the supply tank  558  from being unnecessarily heated by the heater  556   b  of the moisture generator. Additionally, the water stored in the supply tank may be prevented from being contaminated due to heating thereof. 
     The moisture generator  556  may be supported by the moisture supply body  551  or the support body  51  and located in the generator accommodating portion  562 . The moisture generator  556  may be supported by the moisture supply body  551 , rather than the support body  51 , in terms of repair and disassembly of the hanger  5 . 
     Meanwhile, the center of gravity of the hanger  5  having the above-described structure may vary when the amount of water stored in the supply tank  558  changes, when the amount of water stored in the moisture generator  556  changes, and/or when the rpm of the impeller  537   a  increases. 
     Unlike the illustration in  FIG.  14   , when the moisture generator  556  and the supply tank  558  are disposed in the horizontal direction (rather than the vertical direction) it may be difficult to maintain lateral balance of the hanger  5  because the weight of the moisture generator  556  and the weight of the supply tank  558  are different from each other. 
     Therefore, if the center of gravity of the hanger  5  does not remain constant, the laundry hung on the hanger  5  may rotate about the fastening unit  52  (i.e., the hanger may be inclined when the fastening unit has a hook shape), the durability of the fastening unit  52  or a mounting hole  394  may be deteriorated, and/or the hanger  5  may not receive power (when the fastening unit is of a fastening bar type). 
     The above-described laundry treating apparatus  100  enables the user to check laundry, an accessory, and/or the like accommodated in the door chamber  312  through the transparent body  342  of the second door  34  from the outside. However, if the hanger  5  is in an inclined state, and/or if the mounting hole  394  is damaged, the aesthetics of the laundry treating apparatus may be deteriorated. 
     In order to prevent the above problems, among the components of the hanger  5 , relatively heavy components may be disposed such that the centers of the gravity thereof are located between a boundary P 1  (a first boundary) between the base  513  and the first support surface  511  and a boundary P 2  (a second boundary) between the base  513  and the second support surface  512 . 
       FIG.  14    illustrates an example in which the center of gravity of the fan  537 , the center of gravity of the heater  538  of the air supply unit, the center of gravity of the moisture generator  556 , and the center of gravity of the supply tank  558  are located between the first boundary P 1  and the second boundary P 2 . In order to minimize change in the center of gravity of the hanger  5 , the center of gravity of the fan  537 , the center of gravity of the heater  538  of the air supply unit, the center of gravity of the moisture generator  556 , and the center of gravity of the supply tank  558  may be located in a vertical line P 3  that passes through a point at which the fastening unit  52  is secured to the base  513 . 
     However, the structure shown in  FIG.  14    is merely given by way of example. Only two or three of the center of gravity of the fan  537 , the center of gravity of the heater  538  of the air supply unit, the center of gravity of the moisture generator  556 , and the center of gravity of the supply tank  558  may be located between the first boundary P 1  and the second boundary P 2 , and/or may be located in the vertical line P 3 . The reason for this is to enable the hanger  5  to be independently driven even when the fastening unit  52  is not fixedly hung, unlike what is illustrated in  FIG.  14   . 
     If the center of gravity of the hanger  5  is not located below the fastening unit, i.e. (between the first boundary P 1  and the second boundary P 2 ), but is located outside the region between the first boundary P 1  and the second boundary P 2 , unnecessary torque is generated with respect to the fastening unit. 
     In order to prevent this, the center of gravity of the fan  537  and the center of gravity of the moisture generator  556  may be located between the first boundary P 1  and the second boundary P 2 , and/or may be located in the vertical line P 3 . 
     Alternatively, the center of gravity of the moisture generator  556  and the center of gravity of the supply tank  558  may be located between the first boundary P 1  and the second boundary P 2 , and/or may be located in the vertical line P 3 . 
     Alternatively, the center of gravity of the moisture generator  556 , the center of gravity of the supply tank  558 , and the center of gravity of the fan  537  may be located between the first boundary P 1  and the second boundary P 2 , and/or may be located in the vertical line P 3 . 
     Alternatively, the center of gravity of the moisture generator  556 , the center of gravity of the fan  537 , and the center of gravity of the heater  538  of the air supply unit may be located between the first boundary P 1  and the second boundary P 2 , or may be located in the vertical line P 3 . 
     Meanwhile, the center of gravity of the fan may be substituted with the center of rotation of the impeller. 
     The center of gravity of the fan  537  may be determined by the center of gravity of the impeller  537   a  and the center of gravity of the impeller motor  537   b , and the center of gravity of the impeller motor  537   b  may not coincide with the center of rotation of the impeller  537   a.    
     When the center of gravity of the impeller motor  537   b  does not coincide with the center of rotation of the impeller  537   a , it is preferable for the center of rotation of the impeller  537   a  to be located between the first boundary P 1  and the second boundary P 2  or to be located in the vertical line P 3 . Considering the aesthetics of the hanger  5  (the position of the air intake hole) and the amount of air suctioned into the air intake hole  514   a  and distributed to the air exhaust holes  517  formed in each of the first support surface  511  and the second support surface  512 , it is preferable to make the center of rotation of the impeller, rather than the center of gravity of the impeller motor, coincide with the center of gravity of another component. 
     That is, two or more of the center of rotation of the impeller  537   a , the center of gravity of the heater  538  of the air supply unit, the center of gravity of the moisture generator  556 , and the center of gravity of the supply tank  558  may be located between the first boundary P 1  and the second boundary P 2 , and/or may be located in the vertical line P 3 . 
       FIG.  15    shows another example of the hanger  5  of the present disclosure. As shown in  FIG.  15   , when the fastening unit  52  is of a fastening bar type, the fastening-unit terminal  521  needs to be disposed on the free end of the fastening bar. In this example, the support body mounting portion  39  may include a mounting hole  394  that is formed in the door-chamber mounting surface  316  to receive the fastening bar inserted thereinto, and a door terminal  395  that is disposed in the mounting hole and is connected to the power supply. 
     Referring to  FIGS.  7  and  15   , it may be preferable for the air intake hole  514   a  to be located in a region in which suction of external air is disturbed as little as possible by laundry. For example, when the first upper support portion  63  and the second upper support portion  67  described above are provided, the air intake hole  514   a  may be located between the first upper support portion  63  and the second upper support portion  67 . 
     In detail, the uppermost end of the air intake hole  514   a  may be located above a line H that interconnects the first upper support portion  63  and the second upper support portion  67 , and the lowermost end of the air intake hole  514   a  may be located below the line H that interconnects the first upper support portion  63  and the second upper support portion  67 . 
     Although not shown in the drawings, the center of the air intake hole  514   a  may be located in the horizontal line H that interconnects the first upper support portion  63  and the second upper support portion  67 . 
     The reason for this is to prevent the heated air discharged from the first air exhaust holes  517   a  formed in the first top surface  511   a  and the second top surface  512   a  from being immediately suctioned into the air intake hole  514   a . Additionally, it is possible to prevent the moisture or steam discharged from the first discharge holes  518   a  formed in the first top surface  511   a  and the second top surface  512   a  from being immediately suctioned into the air intake hole  514   a . In addition, in order to prevent the water in the supply tank  558  from being unnecessarily heated, the heater  538  and the supply tank  558  need to be spaced apart from each other. Therefore, the air intake hole  514   a  is spaced apart from the supply tank  558 , and it is possible to minimize heating of the region in which the fastening unit  52  is located. 
     Although not mentioned in the above-described embodiments, the cabinet hanger H may be hung on the support body mounting portion  39 . 
     As is apparent from the above description, the present disclosure provides a hanger capable of supplying moisture or air (heated air or non-heated air) to laundry and a laundry treating apparatus including the hanger. 
     In addition, the present disclosure provides a hanger capable of being detachably mounted in a laundry treating apparatus and capable of independently supplying moisture or air to laundry even when the same is separated from the laundry treating apparatus. 
     In addition, the present disclosure provides a hanger capable of maintaining a horizontal orientation by minimizing change in the center of gravity thereof during supply of moisture to laundry and a laundry treating apparatus including the hanger. 
     In addition, the present disclosure provides a laundry treating apparatus including a cabinet chamber, which is provided in a cabinet to define a space for treatment of laundry, and a door chamber, which is provided in a door for opening or closing the cabinet chamber to define a space for treatment of laundry. 
     In addition, the present disclosure provides a hanger, which is provided in the cabinet chamber or the door chamber to define a space in which laundry is supported. 
     In addition, the present disclosure provides a hanger capable of preventing laundry from blocking an air exhaust hole for supplying air and a discharge hole for supplying moisture and a laundry treating apparatus including the hanger. 
     The structure of the hanger and the laundry treating apparatus described above and the control method thereof relate to particular embodiments, and thus the scope of the present application is not limited to the above-described embodiments.
