Title: Laundry treating apparatus

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of Korean Patent Application No. 10-2020-0133272, filed on Oct. 15, 2020, which is hereby incorporated by reference as if fully set forth herein. 
     TECHNICAL FIELD 
     The present disclosure relates to a laundry treating apparatus. 
     BACKGROUND 
     A laundry treating apparatus is a concept including a washing machine for washing laundry (an object to be washed), a dryer for drying the laundry (an object to be dried), and a complex apparatus that performs both the washing and the drying of the laundry. Among conventional laundry treating apparatuses, there is a drawer-type laundry treating apparatus that is located beneath another apparatus (the washing machine, the dryer, or the complex apparatus) and performs the washing of the laundry. 
     The drawer-type laundry treating apparatus is constructed to include a cabinet, a drawer extending from the cabinet, a tub that is disposed in the drawer and stores water therein, a drum that is rotatably disposed inside the tub and stores laundry therein, a water supply pipe that supplies the water to the tub, and a drain pipe that drains the water inside the tub. 
     The drawer-type laundry treating apparatus described above has a risk that the water supply pipe or the drain pipe is twisted inside the cabinet when the drawer is extended from the cabinet or retracted into the cabinet. To solve such problem, among the conventional laundry treating apparatuses, there was one equipped with a support that supports the water supply pipe and the drain pipe inside the cabinet (Korean Patent Application Publication No. 10-2015-0138017). 
     The support disposed in the conventional drawer-type laundry treating apparatus is constructed to include a first support bar rotatably fixed to the cabinet, and a second support bar having one end rotatably fixed to the drawer and the other end connected to the first support. 
     Because the conventional support maintains a state in which the first support bar and the second support bar are connected to each other via a connection shaft, the support part becomes to serve as means for transmitting vibration of the drawer (vibration resulted from rotation of the drum, vibration resulted from movement of the drawer, and the like) to the cabinet. In addition, when the vibration of the drawer is transmitted to the connection shaft, durability of the connection shaft may be lowered. 
     In one example, among the conventional drawer-type laundry treating apparatuses, there were an apparatus having means for supplying detergent to the tub (Korean Patent No. 10-1932471), an apparatus having means for minimizing the water remaining in the tub through a tub exhaust pipe that communicates an interior of the tub with the outside (Korean Patent Application Publication No. 10-2020-0069732), and an apparatus having a pump exhaust pipe that reduces noise of a pump that drains the water stored in the tub. However, in the conventional drawer-type laundry treating apparatus, the means for supplying the water to the tub, the tub exhaust pipe, and the pump exhaust pipe were not able to be designed as an integrated structure, but were only constituted as independent apparatuses. 
     SUMMARY 
     The present application is to provide a laundry treating apparatus that includes a drawer extended from a cabinet, a tub disposed in the drawer to store water therein, a drum disposed inside the tub to store laundry therein, and a door that opens and closes an inlet defined in the tub, and is able to open the inlet even when the door is not withdrawn to the outside of the cabinet.

The leg fastening portion  193  may be defined as a mounting body through-hole defined to penetrate the mounting body  191 , or a mounting body groove defined by concavely bending a surface of the mounting body  191  toward the top cover  15 . 
     As shown in  FIG.  3   , a drawer  3  may be constructed to include a drawer body  21  that is formed in a shape extendable from the cabinet  1 , and provides therein a space in which the accommodating portion  3  is fixed, a drawer cover  23  that forms a top face of the drawer body  21 , and a drawer panel  25  (see  FIG.  1   ) fixed to the drawer body  21  and located outside the cabinet  1 . 
     The drawer body  21  may be formed in any shape capable of being extended from the cabinet  1  through the drawer hole  113 .  FIG.  3    shows a case in which the drawer body  21  is formed in a hexahedral shape with an open top face as an example. The drawer cover  23  is fixed to the open face of the drawer body  21 , and the drawer panel  25  is fixed to a front face of the drawer body  21 . 
     The drawer body  21  may be fixed to the cabinet  1  in an extendable manner through drawer supports  131  and  132 . That is, as shown in  FIG.  2   , a first side face (a face facing the first side cover) of the drawer body  21  may be fixed to the cabinet  1  through a drawer first support  131 , and a second side face (a face facing the second side cover) of the drawer body  21  may be fixed to the cabinet  1  through a drawer second support  132 .

     As shown in  FIG.  1   , the drawer panel  25  may be formed in a shape capable of opening the drawer hole  113  when the drawer body  21  is extended from the cabinet  1 , and closing the drawer hole  113  when the drawer body  21  is retracted into the cabinet  1 . The fact that the drawer hole  113  is opened by the drawer panel  25  means that the drawer hole  113  is exposed to the outside of the laundry treating apparatus, and the fact that the drawer hole  113  is closed means that the drawer hole  113  is not exposed to the outside of the laundry treating apparatus (This does not mean that the drawer hole must be sealed or the drawer panel must be constructed to seal edges of the drawer hole). 
     A control panel  251  is disposed on one face of the drawer panel  25 . An input unit  253  and a display  254  may be disposed on the control panel  251 . The input unit  253  is means for receiving a control command from a user, and the display  254  is means for providing the user with various information related to operation of the laundry treating apparatus. 
     As shown in  FIG.  3   , the drawer cover  23  may be constructed to include a first cover  231  fixed to the top face of the drawer body  21 , and a second cover  236  fixed to the first cover. 
     The drawer cover  23  includes a cover through-hole  237  defined therein for communicating an interior of the drawer body  21  with the outside. The cover through-hole  237  may be defined by coupling a first through-hole  237   a  penetrating the first cover with a second through-hole  237   b  penetrating the second cover  236 . 
     The second cover  236  has a detergent supply hole to which detergent is introduced.  FIG.  3    shows a case in which the detergent supply hole is defined as a first detergent supply hole  236   a  and a second detergent supply hole  236   b  as an example. The first detergent supply hole  236   a  and the second detergent supply hole  236   b  are defined in a space exposed to the outside when the drawer body  21  is extended from the cabinet  1  of a space provided by the drawer cover  23 .  FIG.  3    shows a case in which the first detergent supply hole  236   a  is defined to be located at a right front portion of the second cover  236  (a region close to the drawer panel in a right space of the second cover), and the second detergent supply hole  236   b  is located at a left front portion of the second cover  236  as an example. 
     As shown in  FIG.  4   , the first cover  231  includes detergent flow channels  232 ,  233 ,  234 , and  235  that guide the detergent introduced into the detergent supply hole to the accommodating portion  3 . The detergent flow channels may include a discharge flow channel  232  and  233  that connect the accommodating portion  3  with the first cover  231 , a first detergent flow channel  234  that guides the detergent introduced into the first detergent supply hole  236   a  to the discharge flow channel, and a second detergent flow channel  235  that guides the detergent introduced into the second detergent supply hole  236   b  to the discharge flow channel. 
     The discharge flow channel  232  and  233  may be constructed to include a discharge hole  232  defined to penetrate the first cover  231 , and a discharge pipe  233  that connects the discharge hole  232  and the accommodating portion  3  with each other. In this case, one end of the first detergent flow channel  234  and one end of the second detergent flow channel  235  may be connected to the discharge hole  232  defined at a center of a front portion of the first cover  231 . In order to minimize the vibration of the accommodating portion  3  from being transmitted to the drawer cover  23 , the discharge pipe  233  may be formed as a corrugate pipe. 
     At least one of the first detergent flow channel  234  and the second detergent flow channel  235  may have a detergent storage  239  that provides therein a space for storing the detergent.  FIG.  4    shows a case in which the detergent storage  239  is disposed at the second detergent flow channel  235 . 
     The detergent storage  239  may be constructed to include a storage body  2391  detachable from the drawer cover  23  through the second detergent supply hole  236   b , a water trap  2393  disposed to penetrate a bottom face of the storage body  2391 , and a storage body water supply port  2392  that supplies water to the storage body  2391 . 
     Because the storage body  2391  has a storage body inlet in communication with the second detergent supply hole  236   b  defined in a top face thereof, the detergent introduced into the second detergent supply hole  263   b  may flow to the storage body  2391  through the storage body inlet. 
     The water trap  2393  may be constructed to discharge the water and the detergent inside the storage body  2391  to the second detergent flow channel  235  using a siphon phenomenon. That is, the water trap  2393  may be formed in any shape as long as the water and the detergent may be discharged to the second detergent flow channel  235  when a water level inside the storage body  2391  is equal to or higher than a preset reference water level.  FIG.  4    shows a case in which the water trap  2393  is formed as a storage body discharge pipe protruding from the bottom face of the storage body  2391  and a cap constructed to surround a free end of the storage body discharge pipe as an example. 
     The storage body water supply port  2392  receives the water through a water supply  6  and  7 . A detailed description of the water supply will be described later. 
     Because the first detergent flow channel  234  and the second detergent flow channel  235  are in communication with an external space, foreign substances may be supplied to the accommodating portion  3  through the first detergent flow channel and the second detergent flow channel. In order to minimize a flow of foreign substances existing outside the drawer and foreign substances contained in the water or the detergent to the accommodating portion  3 , a first foreign substance remover  2341  may be disposed in the first detergent flow channel  234 , and a second foreign substance remover  2351  may be disposed in the second detergent flow channel  235 . 
     The first foreign substance remover  2341  may be constructed as a number of protrusions protruding from the first cover  231  toward the second cover  236  are arranged along a width direction of the first detergent flow channel  234  (a Z-axis direction), and the second foreign substance remover  2351  may be constructed as a number of protrusions protruding from the first cover  231  toward the second cover  236  are arranged along a width direction of the second detergent flow channel  235  (the Z-axis direction). 
     As shown in  FIG.  3   , the accommodating portion  3  may be constructed to include a tub  3   a  that is fixed to the drawer body  21  and provides a space therein for storing the water, and a drum  3   b  that is rotatably disposed inside the tub and provides therein a space in which laundry is accommodated. 
     The tub  3   a  may be constructed to include a tub body  31  in which the water is stored, and a tub cover  33  that forms a top face of the tub body. The tub body  31  may be formed in a cylindrical shape with an open top face, and the tub cover  33  may be formed in a cylindrical shape with an open bottom face and be fixed to a top of the tub body  31 . 
     As shown in  FIG.  5   , the tub body  31  is fixed to the drawer body  21  through a tub support  315 . The tub support  315  may be formed as a bar connecting a first bracket  211  disposed on the drawer body  21  and a second bracket  314  disposed on a circumferential face of the tub body. 
     A detergent supply hole  311  through which the detergent is supplied is defined in the circumferential face of the tub body  31 , and a drain hole  313  through which the water inside the tub body is discharged may be defined in a bottom face of the tub body  31 . One end of the discharge pipe  233  is fixed to the detergent supply hole  311 . 
     In the tub cover  33 , an inlet  331  communicating the interior of the tub body  31  with the outside, a water supply hole  332  that supplies the water to the tub body  31 , and an exhaust hole  334  that discharges air inside the tub body  31  are defined. The inlet  331  is opened and closed by the door  4 . A specific structure of the door  4  will be described later. 
     The tub cover  33  may be formed as an inlet defining body in which the inlet  331  is defined, and a cylindrical body extending from an edge of the inlet defining body toward the top of the tub body  31 . In this case, the water supply hole  332  is preferably defined as a hole penetrating the cylindrical body. This is because, when the water supply hole  332  is defined to penetrate the inlet forming body, the water supply hole  332  may be clogged depending on an amount of the laundry stored in the drum  3   b  and an amount of the water supplied to the tub. With the same reason, it is referable that the exhaust hole  334  is also defined in the cylindrical body. 
     The drum  3   b  may be constructed to include a cylindrical drum body  36  with an empty inside, and a drum inlet  37  defined to penetrate a top face of the drum body. 
     The drum body  36  is rotatable inside the tub  3   a  through a driver  38 . The driver  38  may be constructed to include a stator  381  fixed to the bottom face of the tub body  31  to form a rotating magnetic field, a rotor  383  rotating by the rotating magnetic field, and a rotation shaft  385  connecting a bottom face of the drum body  36  with the rotor  383  through a bottom face of the tub body. 
     A drum through-hole  361  is defined in a circumferential face, a bottom face, and the like of the drum body  36 . Therefore, the water stored in the tub body  31  may be supplied into the drum body  36  through the drum through-hole  361 , and water or foreign substances inside the drum body  36  may be discharged to the tub body  31  through the drum through-hole  361 . 
     The drum inlet  37  is located below the inlet  331  that is opened and closed by the door  4 , and the inlet  331  is located below the cover through-hole  237  defined in the drawer cover. In this case, when the drawer  2  is extended from the cabinet  1 , the door  4  located below the cover through-hole  237  will be exposed to the outside of the cabinet  1 . A user may open the door  4  to open the inlet  331 . In such a state, the laundry may be supplied into the drum  3   b , or the laundry stored in the drum may be withdrawn to the outside of the drawer. 
     As shown in  FIG.  3   , the tub  3   a  receives the water through the water supply  6  and  7 , and the water stored in the tub  3   a  is discharged to the outside of the cabinet  1  through a drainage  8 . 
     The drainage  8  may be constructed to include a pump  81  fixed to a rear face of the drawer body (a body rear face)  212  and connected to the tub body  31 , and drain flow channels  84 ,  85 , and  86  that guide the water discharged from the pump to the outside of the cabinet  1 . 
     As shown in  FIG.  5   , the pump  81  may be constructed to include a housing  811  fixed to the body rear face  212 , an impeller rotatable inside the housing, and a pump motor that is fixed to the housing and rotates the impeller. 
     The housing  811  is connected to the tub body  31  through a housing connection pipe  83 . That is, the housing connection pipe  83  may be constructed to connect the drain hole  313  and the housing  811  with each other. 
     When air remains inside the housing  811 , noise and vibration may occur when the impeller rotates. To prevent the air from remaining inside the housing  811 , the pump  81  may further include a housing exhaust hole  812  defined to penetrate the housing. A housing exhaust pipe  813  is connected to the housing exhaust hole  812 . The housing exhaust pipe  813  will be described later. 
     The housing exhaust hole  812  is preferably defined in an area located above a horizontal line passing through a rotation center of the impeller of a space provided by the housing  811 . This is to minimize a risk that the water inside the housing is discharged through the housing exhaust hole  812  when the impeller is rotated. 
     The rear cover  18  includes a fixing member  82  that fixes the drain flow channels. The fixing member  82  may be constructed to include a fixing body  821  fixed to the rear cover  18 , and a fixing pipe  822  that is disposed to penetrate the fixed body, and has one end inside the cabinet  1  and the other end outside the cabinet. In this case, the drain flow channels may be classified into drain pipes  84  and  85  that connect the housing  811  with the fixing pipe  822 , and a drain pipe  86  extending from the fixing pipe  822  toward a sewer. 
     As shown in  FIG.  3   , the water supply may be constructed to include a water source connector  6  connected to a water source, and a dispenser  7  that supplies water supplied from the water supply source connector  6  to at least one of the tub  3   a  and the detergent flow channels  232 ,  233 ,  234 , and  235 . 
     As shown in  FIG.  5   , the water source connector  6  is constructed to be disposed between the rear cover  18  and the body rear face  212  and include connection flow channels  61  and  62  connected to the water source. When the water source is formed as a first water source that supplies water of a first temperature and a second water source that supplies water of a second temperature, the connection flow channels may include a first connection pipe  61  connected to the first water source and a second connection pipe  62  connected to the second water source. The first water source may be formed as a water supply facility (a faucet or the like) that supplies water of a room temperature, and the second water source may be formed as a water supply facility (the faucet or the like) that supplies water having a temperature higher than the room temperature. 
     The first connection pipe  61  may be connected to the first water source through a first water source connector  611 , and the second connection pipe  62  may be connected to the second water source through a second water source connector  621 . In this case, the first water source connector  611  and the second water source connector  621  may be fixed to the rear cover  18 . That is, rear cover through-holes may be defined in the rear cover  18 , and the water source connectors  611  and  621  may be respectively fixed to the rear cover through-holes. 
     As shown in  FIG.  6   , the dispenser  7  may be fixed at a rear portion of the drawer cover  23  (a portion at which the rear cover is located), and may be connected to the first connection pipe  61  and the second connection pipe  62  through a connection pipe control portion  63 . The dispenser  7  may be disposed in an area not exposed to the outside of the cabinet  1  even when the drawer body  21  is extended out of the cabinet  1  of a space provided by the drawer cover  23 . This is to minimize a volume of the laundry treating apparatus by utilizing a space of the drawer  2  that is not exposed to the outside of the cabinet. 
     As shown in  FIG.  7   , the dispenser  7  may include a flow channel body  7   a  fixed to the drawer cover  23 , and a flow channel cover  7   b  that is fixed to the flow channel body to form a top face of the dispenser. 
     In the flow channel body  7   a , water supply flow channels  71  and  72  that define a flow path of the water, and an exhaust flow channel  73  that defines a flow path of the air and defines a flow channel separated from the water supply flow channels may be defined. In this case, a cover through-hole  75  that discharges the air inside the exhaust flow channel  73  to the outside of the dispenser  7  may be defined in the flow channel cover  7   b.    
     The water supply flow channels may include a first water supply flow channel  71  connected to each of the first connection pipe  61  and the second connection pipe  62 , and a second water supply flow channel  72  connected only to the first connection pipe  61  and defining a flow channel separated from the first water supply flow channel  71  and the exhaust flow channel  73 . 
     The connection pipe control portion  63  may be constructed to include a first connection pipe control portion  631 ,  631   a ,  632 , and  632   a  that control supply of the water supplied from the first connection pipe  61  to the first water supply flow channel  71  and the second water supply flow channel  72 , and a second connection pipe control portion  633  and  633   a  that control supply of the water supplied from the second connection pipe  62  to the first water supply flow channel  71 . 
     The first connection pipe control portion may be constructed to include a first control pipe  631   a  that connects the first connection pipe  61  to the first water supply flow channel  71 , a first valve  631  that controls opening and closing of the first control pipe in response to a control signal from a controller C, a second control pipe  632   a  that connects the first connection pipe  61  to the second water supply flow channel  72 , and a second valve  632  that controls opening and closing of the second control pipe based on the control signal from the controller C. 
     The second connection pipe control portion may be constructed to include a third control pipe  633   a  that connects the second connection pipe  62  to the first water supply flow channel  71 , and a third valve  633  that controls opening and closing of the third control pipe in response to the control signal from the controller C. 
     In conventional laundry treating apparatuses, the first connection pipe control portion is fixed to the first water source connector  611  or the rear cover  18 , and the second connection pipe control portion is fixed to the second water source connector  621  or the rear cover  18 . However, in the laundry treating apparatus  100  in the present application, the first connection pipe control portion  631 ,  631   a ,  632 , and  632   a  and the second connection pipe control portion  633  and  633   a  are fixed to the drawer. When the controller C, the first connection pipe control portion  631 ,  631   a ,  632 , and  632   a , and the second connection pipe control portion  633  and  633   a  are fixed to the body rear face  212 , it is possible to minimize a risk that an electric wire that connects the controller C and each of the valves  631 ,  632 , and  633  is tangled inside the cabinet  1 . 
     The first water supply flow channel  71  has a first flow channel first discharge port  713  and a first flow channel second discharge port  715 . A first flow channel water supply pipe  714  that supplies water to the first detergent flow channel  234  may be fixed to the first flow channel discharge port  713 , and a tub water supply pipe  333  that supplies water to the tub  3   a  may be fixed to the first flow channel second discharge port  715 . The first flow channel first discharge port  713  and the first flow channel second discharge port  715  may be disposed on the flow channel body  7   a  or may be disposed on the flow channel cover  7   b .  FIG.  7    shows a case in which the first flow channel first discharge port  713  and the first flow channel second discharge port  715  are disposed on the flow channel body  7   a  as an example. 
     In this case, the first water supply flow channel  71  may include a first flow channel defining portion  71   a  having the first flow channel first discharge port  713 , a second flow channel defining portion  71   b  that connects the first flow channel defining portion  71   a  with the first control pipe  631   a , and a third flow channel defining portion  71   c  that connects the first flow channel defining portion  71   a  with the third control pipe  633   a . Accordingly, the water of the first temperature and the water of the second temperature may be supplied to the first water supply flow channel  71 . 
     The first flow channel second discharge port  715  may be located at a point where the second flow channel defining portion  71   b  and the third flow channel defining portion  71   c  intersect each other. This is to allow the water supplied from the first control pipe  631   a  to also flow to the tub water supply pipe  333  and allow the water supplied from the third control pipe  633   a  to also flow to the tub water supply pipe  333 . 
     A C-shaped flow channel guide  77  that surrounds the first flow channel second discharge port  715  may be further disposed on the flow channel body  7   a . The flow channel guide  77  is constructed to protrude from a bottom face of the flow channel body  7   a  toward the flow channel cover  7   b . A first free end of the flow channel guide  77  may be located in the second flow channel defining portion  71   b , and a second free end of the flow channel guide  77  may be located in the third flow channel defining portion  71   c.    
     The flow channel guide  77  is means for supplying some of water introduced into the second flow channel defining portion  71   b  and the third flow channel defining portion  71   c  to the first flow channel second discharge port  713 , and guiding the rest to the first flow channel second discharge port  715 . Therefore, the dispenser  7  having the above-described structure may supply the water to the first detergent flow channel  234  and the tub  3   a  at the same time (may shorten a water supply time). 
     The second water supply flow channel  72  is constructed to receive the water of the first temperature through the second control pipe  632   a  (connected to the first connection pipe), and the water inside the second water supply flow channel  72  is discharged through a second flow channel discharge hole  722 . The second flow channel discharge hole  722  may be defined in the flow channel body  7   a  or may be defined in the flow channel cover  7   b.    
     A second flow channel water supply pipe  723  that supplies water to the second detergent flow channel  235  is fixed to the second flow channel discharge hole  722 . When the detergent storage  239  is disposed in the second detergent flow channel  235 , the second flow channel water supply pipe  723  may be formed as a hose that connects the second flow channel discharge hole  722  with the storage body water supply port  2392 . 
     The exhaust flow channel  73  may be disposed between the first water supply flow channel  71  and the second water supply flow channel  72  to separate the two water supply flow channels  71  and  72 . The exhaust flow channel  73  may have a tub communication hole  731 , and the tub communication hole  731  may be connected to the tub exhaust hole  334  through the tub exhaust pipe  335 . Accordingly, air inside the tub  3   a  may flow to the cabinet  1  through the tub exhaust hole  334 , the tub exhaust pipe  335 , the tub communication hole  731 , the exhaust flow channel  73 , and the cover through-hole  75 . When communicating the interior of the tub  3   a  with the interior of the cabinet (communicating the interior of the tub with outside air), a problem of the water remaining in the tub may be prevented (hygienic management of the tub and the drum is possible). 
     Further, the exhaust flow channel  73  may further include a housing communication hole  733  defined therein. The housing communication hole  733  is connected to the housing exhaust hole  812  of the pump through the housing exhaust pipe  813  (see  FIG.  5   ). Therefore, the air remaining inside the housing  811  of the pump may be discharged into the cabinet  1  through the housing exhaust pipe  813 , the housing communication hole  733 , the exhaust flow channel  73 , and the cover through-hole  75 . 
     The above-described dispenser  7  includes all of the flow channels  71  and  72  that supply the water to the space where the detergent is stored, the flow channel  71  that supplies the water to the tub, and the flow channel  73  that exhausts the air of the tub and the air of the pump. Accordingly, the present application may provide a laundry treating apparatus capable of minimizing a volume by minimizing an installation space of each of the flow channels  71 ,  72 , and  73 . 
     As shown in  FIG.  4   , the first flow channel water supply pipe  714  and the second flow channel water supply pipe  723  may be fixed to the drawer cover  23 . To this end, the first cover  231  may include a first mounting groove  231   a  in which the first flow channel water supply pipe  714  is accommodated, and a second mounting groove  231   b  in which the second flow channel water supply pipe is accommodated defined therein. Unlike shown in the drawing, the first mounting groove and the second mounting groove may be defined in the second cover  236 . 
     Because the laundry treating apparatus  100  of the above-described structure needs a motion of the drawer body  21  of being extended or retracted from or into the cabinet, the connection flow channels  61  and  62  or the drain flow channels  84 ,  85 , and  86  may be entangled inside the cabinet  1 . 
     In order to solve the above-described problem, the laundry treating apparatus  100  may further include a flow channel support  9 . As shown in  FIG.  5   , the flow channel support  9  is constructed to include a first support  91  that is rotatably fixed to the drawer body  21  and positioned between the rear cover  18  and the body rear face  212 , and a second support  92  that is rotatably fixed to the cabinet  1  and positioned between the rear cover  18  and the body rear face  212 . 
     In this case, it is preferable that a free end of the second support  92  is separated from a free end of the first support  91 . This is because, when the free end of the second support  92  and the free end of the first support  91  are connected to each other, not only the vibration of the drawer body  21  may be transmitted to the cabinet along the flow channel support  9 , but also there is a possibility that a portion that connects the supports  91  and  92  with each other may be damaged by the vibration (a possibility that a problem in which it is difficult to extend or retract the drawer may occur). 
     When the flow channel support  9  is disposed, at least one of the connection flow channels  61  and  62  and the drain flow channels  84 ,  85  and  86  may be fixed to the first support  91  and the second support  92 .  FIG.  5    shows a case in which the connection flow channels  61  and  62  are fixed to the first support  91  and the second support  92 , and the drain flow channels  84 ,  85 , and  86  are also fixed to the first support  91  and the second support  92  as an example. 
     As shown in  FIG.  6   , the first support  91  may be formed as a bar rotatably fixed to the body rear face  212 , and the second support  92  may be formed as a bar rotatably fixed to the fixing member  82 . 
     That is, a fixed end (a first fixed end) of the first support  91  may be rotatably coupled to the body rear face  212 , and a free end (a first free end) of the first support  91  may be positioned between the rear cover  18  and the body rear face  212 . A fixed end (a second fixed end) of the second support  92  may be rotatably coupled to the fixing member  82 , and a free end (a second free end) of the second support  92  may be positioned between the rear cover  18  and the body rear face  212 . The second free end must not be connected to the first free end, and the second free end may be disposed at a point higher than the first free end or at a point lower than the first free end. 
     As shown in  FIGS.  8 A and  8 B , the first support  91  includes a first support body  911  that provides a space in which the connection flow channels  61  and  62  and the drain flow channels  84  and  85  are supported, and a first support rotation shaft  913  that connects the first support body to the body rear face  212 . 
     The first support body  911  fixed to the drawer body  21  may be disposed parallel to a width direction of the body rear face  212  (an X-axis direction) through the first support rotation shaft  913 , and the first support rotation shaft  913  may be disposed at one end of the first support body  911 . In this case, the body rear face  212  must include a first shaft support  317  (see  FIG.  5   ) to which the first support rotation shaft  913  is rotatably coupled. 
     When the controller C (see  FIG.  5   ) is fixed to the body rear face  212 , the first support body  911  may include an inclined body  911   a  inclined downward from a first fixed end  91   a  (one end with the first support rotation shaft), and an extending body  911   b  (an area parallel to a width direction of the body rear face) extending from the inclined body toward the first free end  91   b . This is to prevent the first support body from interfering with the controller C when the drawer  2  is inserted into the cabinet  1  (when the first support body is in contact with the body rear face). 
     As shown in  FIGS.  9 A and  9 B , the second support  92  may be constructed to include a second support body  921  that provides a space in which the connection flow channels  61  and  62  and the drain flow channels  84  and  85  are supported, and a second support rotation shaft  922  rotatably fixing the second support body  921  to the fixing member  82 . 
     The second support body  921  may be disposed parallel to the width direction of the rear cover  18  (the X-axis direction), and the second support rotation shaft  922  may be disposed at a position at which the second support body  921  is positioned above the first support body  911  when the drawer panel  25  closes the drawer hole  113 . 
     The second support rotation shaft  922  may be disposed at a second fixed end  92   a , and the fixing member  82  may include a second shaft support to which the second support rotation shaft  922  is rotatably coupled. That is, as shown in  FIG.  6   , the fixing member  82  may include a second shaft support  823  disposed on the fixing body  821  and coupled to the second support rotation shaft  922 . 
     A support flow channel  923  with an inlet  9231  through which liquid is introduced and an outlet  9232  through which the liquid is discharged may be disposed at the second free end  92   b . In this case, the drain flow channels  84 ,  85 , and  86  may be constructed to include a first drain pipe  84  that connects the housing  811  of the pump with the inlet  9231  of the support flow channel, a second drain pipe  85  that connects the outlet  9232  of the support flow channel with the fixing pipe  822  of the fixing member, and a third drain pipe  86  that guides the water discharged from the fixing pipe  822  to the sewer or ground (a surface on which the cabinet  1  is mounted). 
     As shown in  FIGS.  9 A and  9 B , the second drain pipe  85  may be formed as a corrugate pipe having a structure stretchable in a longitudinal direction, or a pipe made of a material (rubber or the like) that is easily stretchable in the longitudinal direction. This is to minimize a problem that durability of the second drain pipe  85  is deteriorated by an external force input to the second drain pipe  85  when the second support body  921  rotates. For the same reason, the first drain pipe  84  may also be formed as the corrugate pipe or the pipe made of the material that is easily stretchable in the longitudinal direction. 
     In order to prevent the water flowed to the second drain pipe  85  from flowing back to the first drain pipe  84 , a check valve  9233  may be further disposed at the outlet  9232  of the support flow channel. The check valve  9233  may be a valve having any structure as long as the water is allowed to be discharged from the outlet  9232 , but the water is blocked from flowing into the outlet  9232 . 
     As shown in  FIGS.  8 A and  8 B , the first support body  911  has a drain pipe fixing portion  915  to which the first drain pipe  84  is fixed. Because the second drain pipe  85  is fixed to the second support body  921 , the drain pipe fixing portion  915  is preferably disposed on a face facing the rear cover  18  of the space provided by the first support body. 
     To facilitate coupling and separation of the first support body  911  and the first drain pipe  84 , the drain pipe fixing portion  915  may be formed as a U-shaped bracket (in a structure that may minimize deflection of the first drain pipe) that supports a lower space of the first drain pipe  84  (a circumferential face located below a horizontal line passing through a center of the first drain pipe). In this case, the first drain pipe  84  will be detachable from the drain pipe fixing portion  915 . 
     Further, the flow channel support  9  may include a first fastening portion  931  and  933  disposed on the first support body  91  and to which the connection flow channels  61  and  62  are detachably fixed, and a second fastening portion  932  and  934  disposed on the second support body  921  and to which the connection flow channels  61  and  62  are detachably fixed. 
     The first fastening portion may be constructed to include a first connection pipe first fastening portion  931  disposed on the first support body  911  and to which the first connection pipe  61  is detachably fixed, and a second connection pipe first fastening portion  933  disposed on the first support body  911  and to which the second connection pipe  62  is detachably fixed. 
     It is preferable that the first connection pipe first fastening portion  931  and the second connection pipe first fastening portion  933  are disposed on a face facing the body rear face  212  of the space provided by the first support body  911 . This is because, as the connection pipe control portion  63  is fixed to the rear face  212  (body rear face) of the drawer in the above-described laundry treating apparatus  100 , twist of the connection pipes  61  and  62  may be minimized when the first connection pipe first fastening portion  931  and the second connection pipe first fastening portion  933  are formed as described above. 
     It is preferable that the first connection pipe first fastening portion  931  and the second connection pipe first fastening portion  933  are arranged along a height direction of the first support body  911  (a Y-axis direction). That is, the first connection pipe first fastening portion  931  is preferably disposed to be positioned above or below the second connection pipe first fastening portion  933 . This is to minimize a volume of the first support body  911  to which the connection pipes  61  and  62  are fixed (minimize a volume of the laundry treating apparatus). 
     Unlike as shown in the drawing, the first connection pipe first fastening portion  931  and the second connection pipe first fastening portion  933  may be fixed to one of a top face and a bottom face of the first support body  911 . In addition, the first connection pipe first fastening portion  931  may be fixed to one of the top face and the bottom face of the first support body  911 , and the second connection pipe first fastening portion  933  may be fixed to the other of the top face and the bottom face of the first support body  911 . 
     As shown in  FIGS.  9 A and  9 B , the second fastening portion may be constructed to include a first connection pipe second fastening portion  932  disposed on the second support body  921  and to which the first connection pipe  61  is detachably fixed, and a second connection pipe second fastening portion  934  disposed on the second support body  921  and to which the second connection pipe  62  is detachably fixed. 
     The first connection pipe second fastening portion  932  and the second connection pipe second fastening portion  934  may be fixed to a bottom face (a face facing the first support body) of the second support body  921 . In order to minimize a volume of the second support body  921  to which the connection pipes  61  and  62  are fixed, it is preferable that the first connection pipe second fastening portion  932  is positioned above or below the second connection pipe second fastening portion  934 . 
     To facilitate coupling or separation the connection pipes  61  and  62  to or from the second support body  92 , the first connection pipe second fastening portion  932  and the second connection pipe second fastening portion  934  may be formed as C-shaped brackets. In this case, an opened section of the bracket may be directed in a direction facing the rear face  212  of the drawer body  21 . 
     Although not shown in the drawing, the first connection pipe second fastening portion  932  and the second connection pipe second fastening portion  934  may be disposed on a top face of the support body  921 , or may be disposed on a face directed in a direction facing the body rear face  212  of a space provided by the second support body  921 . 
     As shown in  FIG.  10   , when the drawer  2  is extended from the cabinet  1 , the free end of the first support body  911  rotates counterclockwise, and the free end of the second support body  921  rotates clockwise. In this case, the free end of the first support body  911  will rotate in a plane parallel to the bottom face of the cabinet  1  (a X-Z plane), and the free end of the second support body  921  will also rotate in the plane parallel to the bottom face of the cabinet  1  (the X-Z plane). Although not shown in the drawing, the free end of the first support body  911  may rotate clockwise, and the free end of the second support body  921  may rotate counterclockwise. 
       FIG.  10    shows a case in which the plane in which the free end of the first support body  911  rotates is formed at a lower position than the plane in which the free end of the second support body  921  rotates, but the plane in which the free end of the first support body  911  rotates may be formed at a higher position than the plane in which the free end of the second support body  921  rotates (The first support may be changed to be located at a higher point than the second support). 
     The above-described embodiment has been described for the case in which the second support  92  is rotatably disposed on the fixing member  82  fixed to the rear cover  18  of the cabinet  1 . However, the second support  92  may be rotatably disposed on the first side cover  16  or the second side cover  17  of the cabinet, the rear frame  12 , or the like. Likewise, the first support  91  may be rotatably fixed to the drawer cover  23  or one of both side faces of the drawer. 
     Because the connection flow channels  61  and  62  and the drain flow channels  84  and  85  are supported by the flow channel support  9  in the laundry treating apparatus  100  of the above-described structure, it is possible to minimize the problem of the flow channels being entangled inside the cabinet  1  each time the drawer moves. In addition, because the free end of the first support body and the free end of the second support body are separated from each other in the laundry treating apparatus  100  described above, it is also possible to minimize the vibration of the drawer body  21  transmitted to the cabinet  1 . 
     In the laundry treating apparatus  100  of the above structure, the door  4  must be opened after the drawer  2  is extended from the cabinet  1  to put the laundry into the drum  3   b  or withdraw the laundry stored in the drum. Among the conventional laundry treating apparatuses, there was one including the drawer, the tub disposed inside the drawer, the drum disposed inside the tub, and the door that opens and closes the inlet defined in the top face of the tub. The door disposed in the conventional laundry treating apparatus was in a structure of being coupled to a top face of the tub through a hinge. 
     The door rotatably fixed to the top face of the tub through the hinge has following problems. Because a free end of the door in the conventional laundry treating apparatus must be rotated in a direction away from the top face of the tub, in order for the door to open the inlet, the free end of the door had to be rotated to a point higher than the top face of the drawer. In the above-described conventional laundry treating apparatus, the drawer is not able to be retracted into the cabinet with the inlet open. This is because the drawer in the state in which the door opened the inlet may not be extended from the cabinet. 
     The fact that the drawer is not able to be retracted into the cabinet in the state in which the door opened the inlet means that the drawer must be extended from the cabinet when the tub and drum are dried by opening the inlet. This means that foreign substances may flow into the tub or the drum through the inlet when the water remaining in the tub and drum is to be evaporated. In addition, because the drawer must always be kept extended from the cabinet, there are disadvantages in that a space in front of the cabinet must be emptied as a space in which the drawer is extended, and durability of an apparatus that supports the drawer (such as a drawer support or the like) is deteriorated. 
     In order to solve the above-described disadvantages and problems, the door  4  in the laundry treating apparatus  100  is constructed to reciprocate between a first point of closing the inlet  331  and a second point of opening the inlet  331 . In this case, the first point and the second point are set as points located in a space defined between the tub cover  33  and the drawer cover  23 . 
       FIGS.  11  and  12    show an example of the laundry treating apparatus  100  capable of opening and closing the inlet  331  in the above-described manner.  FIG.  11    shows that the door  4  is located at the first point P 1  and closes the inlet  331 , and  FIG.  12    shows that the door  4  is positioned at the second point P 2  and opens the inlet  331 . 
     The laundry treating apparatus  100  may include the door  4  that closes the inlet  331 , and a door guide  5  that allows the door to reciprocate between the first point P 1  and the second point P 2  but not to deviate from the interior of the drawer body  21 . 
     As shown in  FIG.  13   , the door  4  may be constructed to include a door frame  41  and  42  located in a space between the tub cover  33  and the drawer cover  23 , and a closing portion  43  disposed in the door frame to close the inlet  331 . The door frame  41  and  42  may include a base frame  41  positioned on the tub cover  33  to form a bottom face of the door, and a cover frame  42  that is fixed to the base frame and forms a top face of the door. 
     To allow the door to reciprocate between the first point P 1  and the second point P 2 , the door frame  41  and  42  should be formed in shape that does not contact the drawer body  21  at the first point and the second point. In addition, to facilitate the insertion of the laundry when the door is positioned at the second point, it is preferable that the second point is set as a point at which 80% or more of the inlet  331  is opened. 
     The door frame  41  and  42  may include a frame through-hole  421  defined therein. The closing portion  43  may be fixed to the door frame  41  and  42  so as to be positioned in the frame through-hole  421 . The closing portion  43  is constructed to protrude from the base frame  41  and be inserted into the inlet  331 . The closing portion  43  may be formed in a shape of a pillar having a bottom face corresponding to a shape of the inlet  331 . In order to identify the interior of the tub  3   a  from the outside of the drawer  2 , the closing portion  43  may be made of a transparent material. In this case, the closing portion will serve as a window. 
     The frame through-hole  421  may be defined by a base frame through-hole  421   a  defined to penetrate the base frame and a cover frame through-hole  421   b  defined penetrate the cover frame. In this case, the closing portion  43  may include a closing portion body inserted into the inlet  331 , and a flange fixed between the base frame  41  and the cover frame  42  such that the closing portion body is located in the frame through-hole  421 . 
     The door  4  may have a door lock  455  that detachably fixes the door frame  41  and  42  to the tub cover  33 . As shown in  FIG.  14   , the door lock may be constructed to include a lock body  456  disposed on the door frame  41  and  42 , and a lock fastening portion  459  disposed on the tub cover  33  and to which the lock body  456  is coupled. 
     When a handle  45  is disposed on the door frame  41  and  42 , the lock body  456  may be fixed to the handle  45 . As shown in  FIG.  13   , the handle  45  may be constructed to include a handle body  451  positioned at a front portion of the door frame  41  and  42 , and a handle shaft  453  fixed between the base frame  41  and the cover frame  42  so as to rotatably fix the handle body to the door frame. In this case, the lock body  456  may be formed as a hook or the like protruding from the handle body  451  toward the tub cover  33 . 
     As shown in  FIG.  14   , the lock fastening portion  459  is disposed in an area located in front of the inlet  331  in a space provided by the tub cover  33 . Therefore, when the door closes the inlet  331  (when the door is located at the first point), the door lock  455  will fix a space in front of the door frame  41  and  42  (a space that is close to the drawer panel based on a horizontal line that passes through a center of the frame through-hole and is parallel to the X axis) to the tub cover  33  located in a space in front of the inlet  331  (a space that is close to the drawer panel based on a horizontal line that passes through a center of the inlet and is parallel to the X axis). 
     As shown in  FIG.  15   , the door guide  5  is constructed to include a first guide  51 , a second guide  52 , and a third guide  53  that provide a path along which the door  4  reciprocates between the first point P 1  and the second point P 2 . 
     The first guide  51  and the second guide  52  may be respectively located in a space of the tub cover  33  to the left of the inlet  331  (a space that is close to the first side cover based on a horizontal line that passes through the center of the inlet and is parallel to the Z-axis) and a space of the tub cover  33  to the right of the inlet  331  (a space that is close to the second side cover based on the horizontal line that passes through the center of the inlet and is parallel to the Z-axis). In addition, the third guide  53  may be located in a rear space of the tub cover  33  (a space that is close to the body rear face based on the horizontal line that passes through the center of the inlet and is parallel to the X-axis), and be located between the first guide  51  and the second guide  52 . The third guide  53  may extend from a rear end of the inlet  331  toward a rear end of the tub cover  33 . The first guide  51 , the second guide  52 , and the third guide  53  are parallel to each other. 
     The door frame  41  and  42  has a slide  47  coupled to the door guide  5 . As shown in  FIG.  13   , the slide  47  may be constructed to include a first slide  471  disposed on the base frame  41  and connected to the first guide  51 , a second slide  472  disposed on the base frame  41  and connected to the second guide  52 , and a third slide  473  disposed on the base frame  41  and connected to the third guide  53 . 
     The first slide  471  and the second slide  472  are respectively on a left side (a side that is close to the first side cover based on the horizontal line that passes through the center of the frame through-hole and is parallel to the Z-axis) and a right side of the base frame  41  with the closing portion  43  interposed therebetween. In addition, the third slide  473  may be disposed on the base frame  41  so as to be located at the rear of the closing portion  43 . Each of the slides  471 ,  472 , and  473  may be composed of a slide body that is fixed to the base frame  41 , and a sliding protrusion protruding from the slide body and inserted into each of the guides  51 ,  52 , and  53 . 
     When the closing portion  43  is constructed to close the inlet  331  by being inserted into the inlet  331 , it is preferable that each of the guides  51 ,  52 , and  53  includes a detachment path that guides the slide in a direction from the tub cover  33  to the drawer cover  23 , and a transfer path that guides the slide from the detachment path to a rear portion of the tub cover  33 . 
     That is, as shown in  FIG.  16   , the first guide  51  may be constructed to include a first detachment path  513  that guides the first slide  471  in the direction from the tub cover  33  to the drawer cover  23 , and a first transfer path  511  that guides the first slide  471  from an end of the first detachment path  513  to the rear portion of the tub cover  33 . Similarly, the second guide  52  may be constructed to include a second detachment path  523  that guides the second slide  472  in the direction from the tub cover  33  to the drawer cover  23 , and a second transfer path  521  that guides the second slide  472  from an end of the second detachment path  513  to the rear portion of the tub cover  33 . The third guide  53  may be constructed to include a third detachment path  533  that guides the third slide  473  in the direction from the tub cover  33  to the drawer cover  23 , and a third transfer path  531  that guides the third slide  473  from an end of the third detachment path  533  to the rear portion of the tub cover  33 . 
     In order to prevent the closing portion  43  from interfering with the tub cover  33  and to reduce a force required for the movement of the door  4  when the door  4  moves toward the first point P 1  (see  FIG.  11   ), the first detachment path  513 , the second detachment path  523 , and the third detachment path  533  may be inclined. That is, each of the first detachment path  513 , the second detachment path  523 , and the third detachment path  533  may be a path with an inclination to be further away from the tub cover  33  in a direction from the inlet  311  to the rear portion of the tub cover  33 . 
     It is preferable that an inclination angle of the first detachment path  513 , an inclination angle of the second detachment path  523 , and an inclination angle of the third detachment path  533  are set to be the same. In addition, it is preferable that the first transfer path  511 , the second transfer path  521 , and the third transfer path  531  are parallel to each other along a moving direction of the door frame  41  and  42  (a moving direction of the drawer). 
     In one example, because the tub  3  may vibrate when the drum  3   b  rotates, and the closing portion  43  may be separated from the inlet  331  when the tub vibrates, the door  4  and the tub cover  33  may respectively further include a stopper and a stopper fastening portion that prevents the door  4  from easily deviating from the first point P 1 . The stopper fastening portion may be disposed on the tub cover  33  as means for limiting the movement of the door by being coupled to the stopper when the door  4  reaches the first point P 1 . 
     As shown in  FIGS.  13  and  14   , a stopper  48  may include a first stopper  481  and a second stopper  482  defined in the base frame  421   a , and the stopper fastening portion may include a first stopper fastening portion  338  disposed on the tub cover  33  and to which the first stopper  481  is detachably coupled, and a second stopper fastening portion  339  to which the second stopper  482  is detachably coupled. 
     The first stopper  481  may be defined at a point located between the third slide  473  and the first slide  471  in the rear space of the base frame  41 , and the second stopper  482  may be defined at a point located between the third slide  473  and the second slide  472  in the rear space of the base frame  41  (see  FIG.  13   ). 
     In this case, the first stopper fastening portion  338  should be disposed at a point located between the third guide  53  and the first guide  51  in space at the rear of the inlet  331 , and the second stopper fastening portion  339  should be disposed at a point located between the third guide  53  and the second guide  52  in the space at the rear of the inlet  331  (see  FIG.  14   ). 
     As shown in  FIG.  17   , the second stopper fastening portion  339  may include a second stopper guide  3391  that guides the second stopper  482  in the direction from the drawer cover  23  to the tub cover  33 . Similarly, the first stopper fastening portion  338  may include a first stopper guide (not shown) that guides the first stopper  481  in the direction from the drawer cover  23  to the tub cover  33 . It is preferable that an inclination angle of the first stopper guide and an inclination angle of the second stopper guide  3331  are set equal to the inclination angle of the detachment paths  513 ,  523 , and  533 . 
     When the door  4  is located at the first point P 1  and closes the inlet  331 , the lock body  456  of the door lock is fixed to the lock fastening portion  459 , the first slide  471  is located at the lowest point of the first detachment path  513 , the second slide  472  is located at the lowest point of the second detachment path  523 , and the third slide  473  is located at the lowest point of the third detachment path  533 . Further, the first stopper  481  is located at the lowest point of the first stopper guide, and the second stopper  482  is located at the lowest point of the second stopper guide  3391 . Therefore, it means that the front area of the door frame  41  and  42  is fixed to the area of the tub cover  33  located in front of the inlet  331  through the door lock  45 , the spaces on both sides of the door frame  41  and  42  are respectively fixed to both side faces of the tub cover  33  next to the inlet  331  by the first slide  471 , the first guide  51 , the second slide  472 , and the second guide  52 , and the rear area of the door frame  41  and  42  is fixed to the area of the tub cover  33  at the rear of the inlet  331  by the third slide  473 , the third guide  53 , the first stopper  481 , the first stopper fastening portion  338 , the second stopper  482 , and the second stopper fastening portion  339 . This means that the door  4  is fixed to the tub cover  33  through six fastening points. 
     The door in the conventional laundry treating apparatus was fixed to the tub cover through the door lock disposed on the handle, and two hinges disposed at the rear of the door. This means that the conventional door was fixed to the tub cover through a total of three fastening points. Because the number of fastening points in the laundry treating apparatus of the present application are greater than the number of fastening points in the conventional laundry treating apparatus, the laundry treating apparatus  100  may minimize a risk that the door  4  opens the inlet  331  by the vibration of the tub. 
     When the handle body  451  is rotated in such a state, the lock body  456  is separated from the lock fastening portion  459 . When the lock body  456  is separated from the lock fastening portion  459 , the front area of the door frame  41  and  42  will be separated from the tub cover  33 . In addition, when the user pushes the door frame  41  and  42  to the rear of the drawer body, the door  4  will move from the first point P 1  to the second point P 2 . As shown in  FIG.  12   , when the door is located at the second point P 2 , the inlet  331  will be opened. 
     Even when the inlet  331  is open, because the inlet  331  is located inside the drawer body  21 , the user may retract or extend the drawer  2  in the state in which the inlet  331  is open into or from the cabinet  1 . Therefore, the laundry treating apparatus  100  described above may dry the tub and the drum without extending the drawer from the cabinet. 
     In order to minimize the water remaining in the door  4 , a rear portion of the door  4  positioned at the second point P 2  may be positioned at a higher point than a front portion of the door. That is, at least one of the first transfer path  511 , the second transfer path  521 , and the third transfer path  531  may be inclined.  FIG.  12    shows an example of a case in which the third transfer path  531  is inclined (A) toward the drawer cover  23  in a rearward direction of the tub cover  33 . 
     In the above-described embodiment, the door guide  5  has been described as including all of the first guide  51 , the second guide  52 , and the third guide  53 , but the door guide  5  may include only the first guide and the second guide (the slide only includes the first slide and the second slide), or may include only the third guide (the slide includes only the third slide). 
     In a state in which the laundry treating apparatus does not operate, it is not necessary to determine whether the door  4  has opened the inlet  331 . However, it is preferable that the inlet  331  is controlled to be maintained in the closed state during the operation of the laundry treating apparatus (a state in which the drum is rotating, a state in which the water is being supplied to the tub, a state in which the water in the tub is being drained, and the like). The laundry treating apparatus  100  may further include a position sensing portion  49  to determine whether the door  4  has closed the inlet  331 . 
       FIGS.  13  and  15    show an example of the position sensing portion  49 . A case in which the position sensing portion  49  is composed of a pressing portion  495  (see  FIG.  13   ) protruding from the door frame  41  and  42  toward the tub cover  33 , and a signal generator  491  and  493  (see  FIG.  15   ) that is disposed on the tub cover  33 , and comes into contact with the pressing portion  495  when the door is located at the first point is shown as an example. As shown in  FIG.  15   , the signal generator may include a contact portion  491  that comes into contact with the pressing portion  495  when the door  4  is positioned at the first point, and a switch  493  that closes a circuit that generates a control signal when the contact portion is in contact with the pressing portion. The signal generator  491  and  493  having the above-described structure may be fixed to a sensor mounting portion  496  disposed on the tub cover. 
     Unlike the above, the signal generator  491  and  493  may transmit a control signal to the controller C when the door is located at the second point. 
     For sealing the inlet  331 , a gasket  35  may be further disposed in the laundry treating apparatus  100 . For fixing the gasket  35 , the tub cover  33  may include a mounting groove  336  that defines a space in which the gasket  35  is supported therein, and a gasket cover  34  that prevents the gasket  35  from being separated from the mounting groove  336 . 
     The mounting groove  336  may be defined as a ring-shaped groove surrounding the inlet  331 , and the gasket cover  34  may be constructed to be detachable from the tub cover  33 . The mounting groove  336  may have a fixing protrusion  337  that fixes the gasket  35  into the mounting groove. 
     The gasket cover  34  includes an inlet communication hole  345  defined therein in communication with the inlet  331 . The above-described first stopper  481 , second stopper  482 , signal generator  491  and  493 , and lock fastening portion  459  may be disposed below the gasket cover  34 . The first stopper  481 , the second stopper  482 , the sensor mounting portion  496 , and the lock fastening portion  459  are not exposed to the outside, thereby increasing durability of the apparatuses. In this case, the gasket cover  34  should include a cover first through-hole  341  and a cover second through-hole  342  that respectively expose the first stopper  481  and the second stopper  482  to the outside, a cover third through-hole  343  that exposes the signal generator to the outside, and a cover fourth through-hole  344  (lock through-hole) that exposes the lock fastening portion  459  to the outside defined therein. 
     As shown in  FIG.  18   , the gasket  35  may be constructed to include a fastening body  351  seated in the mounting groove  336 , a fastening body through-hole  352  defined to penetrate the fastening body  351  and in communication with the inlet  331 , and a sealing body  355  protruding from the fastening body  351  toward the center of the inlet  331 . 
     The fastening body  351  includes a fastening hole  353  including a plurality of fastening holes that is coupled to the fixing protrusion  337 . The fastening hole  353  may include three front through-holes defined in an area of the fastening body  351  located in front of the inlet  331 , three rear through-holes defined in an area of the fastening body  351  located at the rear of the inlet  331 , and a left through-hole and a right through-hole located between the front through-holes and the rear through-holes and respectively located on areas to the left and to the right of the inlet  331 . In this case, the fixing protrusion  337  should include three front fixing protrusions respectively inserted into the front through-holes, three rear fixing protrusions respectively inserted into the rear through-holes, a left fixing protrusion inserted into the left through-hole, and a right fixing protrusion inserted into the right through-hole. 
     The sealing body  355  may be formed in various shapes and structures as long as it may be compressed between the closing portion  43  and the inlet  331  when the door  4  is located at the first point P 1 . 
     The gasket  34  of the above-described structure seals the inlet  331  by being pressurized when the door  4  is located at the first point P 1 . That is, when the door is located at the first point, the sealing body  355  fills a gap between an outer circumferential face of the closing portion  43  and the inlet  331  while being pressurized toward an edge of the inlet  331  by the outer circumferential face of the closing portion  43 . 
     The gasket that seals the inlet was also disposed in the conventional laundry treating apparatus. However, as mentioned above, the door in the conventional laundry treating apparatus was fixed to the tub cover through the door lock disposed on the handle and the two hinges disposed at the rear of the door. This means that an external force required to seal the inlet by deforming the gasket is supplied to the gasket through three points, and a gap between points to which the external force is input is wide. When the gap between the points that supply the external force to the gasket is wide, despite the presence of the gasket, the water in the tub may leak to the outside through the inlet  331 . 
     As described above, the laundry treating apparatus  100  disclosed in the present application includes the slide  47 , the door guide  5 , the door lock  455 , the stopper  48 , and the stopper fastening portion  338  and  339 . Therefore, the laundry treating apparatus  100  of the above-described structure may pressurize the gasket  35  at a minimum of 4 points and a maximum of 6 points. 
     The four points may be set as one door lock  455 , three slides  471 ,  472 , and  473 , and the door guides  51 ,  52 , and  53 . In this case, the door lock  455  will press an area of the gasket  35  located in front of the inlet  331 , and the third slide  473  and the third guide  53  will press the area of the gasket  35  located at the rear of the inlet  331 . In addition, the first slide  471  and the first guide  51  will press the area of the gasket  35  to the left of the inlet  331 , and the second slide  472  and the second guide  52  will press the area of the gasket  35  to the right of the inlet  331 . The laundry treating apparatus  100  having such a structure may lower the risk of leaking water or air to the inlet  331  compared to the conventional laundry treating apparatus. 
     In one example, as the six points, in addition to the four points described above, the first stopper  481 , the first stopper fastening portion  338 , the second stopper  482 , and the second stopper fastening portion  339  press the area of the gasket  35  at the rear of the inlet  331 . Therefore, the structure of pressing the gasket  35  at the six points will be able to seal the inlet  331  more effectively. 
     To implement the above-described effect, the lock body  456  and the lock fastening portion  459  may be constructed to press the sealing body  355  in a direction in which the closing portion  43  is positioned when the lock body  456  is coupled to the lock fastening portion  459 .
