     DETAILED DESCRIPTION 
     As illustrated in  FIGS. 1, 2 and 3 , an example laundry treatment apparatus  100  may include a cabinet  2 , a drawer  3  provided so as to be discharged from the cabinet  2 , a tub  4  (see  FIG. 2 ) provided inside the drawer  3  for storing water therein, and a drum  5  (see  FIG. 3 ) rotatably provided inside the tub  4  for storing laundry therein. 
     As illustrated in  FIG. 1 , the cabinet  2  may serve to define the external appearance of the laundry treatment apparatus  100 , and may also serve as a space in which the drawer  3  is received. In some implementations, the cabinet  2  may be provided in the front surface thereof with an opening  21  for the insertion of the drawer  3  (e.g. drawer introduction/discharge opening). 
     The drawer  3  includes a drawer body  31  configured to be inserted to the inside of the cabinet  2  through the opening  21 , a drawer panel  33  fixed to the front surface of the drawer body  31  for opening and closing the opening  21 , and a drawer cover  35  for forming the upper surface of the drawer body  31 . 
     Because the drawer panel  33  is fixed to the front surface of the drawer body  31 , the drawer panel  33  may serve as a handle for discharging the drawer body  31  from the cabinet  2 . 
     The drawer panel  33  may be provided with a control panel  331 , which is used to input a control command associated with the operation of the laundry treatment apparatus  100  and to notify a user of a message associated with the operation of the laundry treatment apparatus  100 . 
     The drawer body  31  may have any shape so long as it can be inserted into the cabinet  2  through the opening  21  and can provide a space in which the tub  4  is received.  FIG. 1  illustrates the drawer body  31  having an empty hexahedral shape by way of example. 
     The drawer  3  may be discharged from the cabinet  2  by a drawer guide. The drawer guide may include a slider  371  fixed to the side surface of the drawer body  31 , and a slider receiving member  373  provided inside the cabinet  2  for receiving the slider  371  therein (see  FIG. 3 ). 
     The drawer cover  35  has a first through-hole  351  and a second through-hole  353  for communicating the inside of the drawer body  31  with the outside. The first through-hole  351  is provided for the introduction and discharge of laundry, and the second through-hole  353  is provided to supply water required to wash the laundry. A detailed description related thereto will follow. 
     As illustrated in  FIG. 2 , the tub  4  includes a tub body  41  located inside the drawer body  31  for storing water therein, and a tub cover  43  for forming the upper surface of the tub body  41 . The tub body  41  may take the form of a cylinder having an open upper surface. 
     The tub cover  43  may have an introduction aperture  431  for communicating the inside of the tub body  41  with the outside of the tub body  41 , and a supply aperture  433  for introducing water into the tub body  41 . 
     The introduction aperture  431  may be provided so as to communicate with the first through-hole  351  provided in the drawer cover  35 , and the supply aperture  433  may be provided so as to communicate with the second through-hole  353  provided in the drawer cover  35 . That is, the introduction aperture  431  may be located under the first through-hole  351 , and the supply aperture  433  may be located under the second through-hole  353 . 
     The introduction aperture  431  serves to allow laundry to be introduced into the tub body  41 , or to allow the laundry inside the tub body  41  to be discharged to the outside of the tub body  41 . The introduction aperture  431  is opened and closed by a door  45 . 
     As illustrated in  FIG. 3 , the door  45  may include a frame  451  rotatably coupled to the tub cover  43  via a hinge  453 , a window  455  provided in the frame  451 , and a door handle  457  for separably coupling the frame  451  to the tub cover  43 . The window  455  may be formed of a transparent material to allow the user to view the inside of the tub body  41 . 
     The drum  5 , which is provided inside the tub  4 , may include a cylindrical drum body  51  having an opening  53  formed in the upper surface thereof. Because the opening  53  is located below the introduction aperture  431 , the laundry supplied through the introduction aperture  431  may be supplied to the drum body  51  through the opening  53 . 
     As illustrated in  FIG. 2 , a plurality of drum through-holes  59  may be provided in a bottom surface  57  and a circumferential surface  59  of the drum body  51  for communicating the inside of the drum body  51  with the tub body  41 . 
     The drum body  51  may be rotated inside the tub body  41  by a drive unit. The drive unit may include a stator M 1  located outside the tub body  41  and fixed to the bottom surface of the tub body  41 , a rotor M 2  configured to be rotated by a rotating magnetic field provided by the stator M 1 , and a rotating shaft M 3  penetrating the bottom surface of the tub body  41  for connecting the bottom surface  57  of the drum  5  and the rotor M 3  to each other. In some implementations, the rotating shaft M 3  may be orthogonal to the bottom surface of the tub body  41 . 
     The tub  4  having the configuration described above may be coupled to the drawer body  31  via a tub support unit  6 . The tub support unit  6  may include a first support member  61  provided at the drawer body  31 , a second support member  63  provided at the tub body  41 , and a connector  65  for connecting the first support member  61  and the second support member  63  to each other. 
     As illustrated in  FIG. 3 , the connector  65  may include a first connection piece  651  seated in the first support member  61 , a second connection piece  653  for supporting the second support member  63 , and a bar  655  for connecting the first connection piece  651  and the second connection piece  653  to each other. 
     The first connection piece  651  may be shaped so as to be movable in the first support member  61  while being seated in the first support member  61 . The second connection piece  653  may be shaped so as to support the second support member  63  and to be movable in the second support member  63 . 
       FIG. 3  illustrates the first connection piece  651  and the second connection piece  653 , which have a semispherical surface in contact with the respective support members  61  and  63  by way of example, and  FIG. 4  illustrates the first connection piece  651  and the second connection piece  653 , which have a spherical shape by way of example. 
     As illustrated in  FIG. 4 , the respective support members  61  and  63  may be provided at a position so that the bar  655  is orthogonal to the bottom surface of the cabinet  2  (e.g. a position so that the bar  655  is orthogonal to the bottom surface of the drawer  3 ). 
     In some implementations, because at least three tub support units  6  are provided to couple the tub body  41  to the drawer body  31  and the bars  655  are orthogonal to the bottom surface of the drawer body  31 , the distance between the tub cover  43  and the drawer cover  35  may be increased compared to the case where the bars  655  are tilted by a prescribed angle relative to the Z-axis (the height direction of the tub  4 ) (S 1 &gt;S 2 ). 
     In some implementations, the tub support units  6  may reduce the possibility of the tub cover  43  colliding with the drawer cover  35  even if the tub body  41  vibrates inside the drawer body  31 . 
     When the bars  655  are provided so as to be orthogonal to the bottom surface of the drawer body  31 , some of the first support members  61  may be separably coupled to the drawer body  31 . 
     When at least three tub support units  6  are provided and the first support members  61  are not separable from the drawer body  31 , a worker who attempts to fix the tub body  41  to the drawer body  31  first needs to insert the tub body  41  into the drawer body  31  so as to prevent the first support members  61  from interfering with the second support members  63 , and thereafter needs to rotate the tub body  41  so that the second support members  63  and the first support members  61  are located on the vertical axis, in order to couple the first connection pieces  651  to the first support members  61 . 
     Although the feature by which the bars  655  of the tub support units  6  are orthogonal to the bottom surface of the drawer  3  serves to minimize the distance between the outer circumferential surface of the tub body  41  and the inner circumferential surface of the drawer body  31  (S 3 &lt;S 4 ) so as to minimize the volume of the laundry treatment apparatus  100 , the strength of assembly of the first connection pieces  651  and the first support members  61  may be deteriorated while the process described above is performed. This problem may be solved by making some of the first support members  61  be separable from the drawer body  31 . 
       FIG. 3  illustrates an example where four tub support units  4  are provided by way of example. In some implementations, the first support members  61  may include a pair of first brackets  611  arranged on the surface on which the drawer panel  33  is located (e.g. the front surface of the drawer  3 ), and a pair of second brackets  615  arranged on the rear surface of the drawer  3 . When the drawer body  31  has a hexahedral shape, the two first brackets  611  and the two second brackets  615  may be provided at the respective corners of the drawer body  31 . 
     In some implementations, the pair of first brackets  611  may be arranged on the left side surface of the drawer body  31 , and the pair of second brackets  615  may be arranged on the right side surface of the drawer body  31 . 
     In some implementations, at least one pair of the first brackets  611  and the second brackets  615  may be separably coupled to body separable coupling pieces  311  fixed to the drawer body  31  (when three tub support units  6  are provided, at least one first support member  61  may be separably coupled to the drawer body  31 ). 
       FIG. 3  illustrates an example where the pair of first brackets  611  is separable from the drawer body  31 , but the pair of second brackets  615  is not separable from the drawer body  31  by way of example. 
     When the first brackets  611  are separably coupled to the body separable coupling pieces  311 , the coupling of the tub body  41  and the drawer body  31  may be performed as follows. 
     The worker couples the connectors  65  to the four second support members  63  provided on the circumferential surface of the tub body  41 , and then couples a pair of connectors  65 , selected from among the fourth connectors  65 , to the second brackets  615  arranged on the rear surface of the drawer  3 . 
     Once a pair of the first connection pieces  651  is seated on the respective second brackets  615 , the worker may couple the tub body  41  and the drawer body  31  to each other by coupling the first brackets  611  to the two remaining connectors  65 , and then fixing the first brackets  611  to the body separable coupling pieces  311 . 
     In some implementations, the laundry treatment apparatus may prevent the possibility of deterioration in the strength of assembly of the tub body  41  and the drawer body  31  by arranging the connectors  65  so as to be orthogonal to the bottom surface of the drawer  3 . 
     In order to improve the strength of assembly of the tub body  41  and the drawer body  31 , the first brackets  611  may be integrally formed with the connectors  65 . That is, when the tub body  41  and the drawer body  31  are assembled to each other, the first brackets  611  coupled to the first connection pieces  651  may be provided to the worker. Each of the first brackets  611  may include a receiving recess for supporting the first connection piece  651 , a through-hole for the penetration of the bar  655 , and a connector cover for preventing the first connection piece  651  supported in the receiving recess from being separated from the receiving recess. 
     In order to ensure that the tub body  41  coupled via the tub support units  6  described above is movable in the X-Y plane, each of the second brackets  615  may include a through-hole  615   c  for the penetration of the bar  655  of the connector  65 , a receiving recess  615   a  for supporting the first connection piece  651 , and a slit  615   b  for allowing the bar  655  to be inserted toward the center of the through-hole  615   c  from the edge of the through-hole  615   c.    
     The first bracket  611  may have the same shape as the second bracket  615 . That is, as illustrated in  FIG. 5 , the first bracket  611  may include a through-hole  611   c  for the penetration of the bar  655  of the connector  65 , a receiving recess  611   a  for supporting the first connection piece  651 , and a slit  611   b  for allowing the bar  655  to be inserted toward the center of the through-hole  611   c  from the edge of the through-hole  611   c.    
     The first bracket  611  may be coupled to the body separable coupling piece  311  via a fastening structure. The fastening structure may include a first fastening hole  611   d  formed in the first bracket  611 , a second fastening hole  312  formed in the body separable coupling piece  311 , and a coupler C inserted through the respective fastening holes. 
     The second support member  63  provided at the tub body  41  may include a through-hole  635  (see  FIG. 3 ) for the penetration of the bar  655  of the connector  65 , a receiving recess  631  provided on the edge of the through-hole  635  so as to be seated on the second connection piece  653 , and a slit  633  for allowing the bar  655  to be inserted toward the center of the through-hole  635  from the edge of the through-hole  635 . 
     The laundry treatment apparatus  100  having the configuration described above may supply water to the tub  4  via a water supply unit  7 , and may discharge water stored in the tub  4  to the outside of the cabinet  2  via a drain unit  8 . 
     As illustrated in  FIG. 2 , the water supply unit  7  may include a first water supply pipe  71  connected to the supply aperture  433  formed in the tub cover  43 , a second water supply pipe  73  connected to a water supply source, which is located at the outside of the cabinet  2 , and a connection pipe  75  fixed to the tub cover  43  for connecting the first water supply pipe  71  and the second water supply pipe  73  to each other. 
     The first water supply pipe  71  may connect the supply aperture  433  and the connection pipe  75  to each other through the second through-hole  353  provided in the drawer cover  35 . The first water supply pipe  71  may be a corrugated pipe in order to prevent the first water supply pipe  71  from being separated from the connection pipe  75  when the tub  4  vibrates (see  FIG. 3 ). 
     In addition, the second water supply pipe  73  may also be a corrugated pipe in order to prevent the second water supply pipe  73  from being separated from the connection pipe  75  when the drawer  3  is discharged from the cabinet  2 . The second water supply pipe  73  may be opened and closed by a water supply valve  77 , which is controlled by a controller. 
     In some implementations, unlike the illustration of  FIG. 2 , the water supply unit  7  may include a single water supply pipe for connecting a water supply source, which is located at the outside of the cabinet  2 , to the supply aperture  433  provided in the tub cover  43 . In some implementations, at least a region of the water supply pipe may form a corrugated pipe. 
     The drain unit  8  may include a drain pump  81  fixed to the drawer body  31 , a first drain pipe  83  for guiding water inside the tub body  41  to the drain pump  81 , and a second drain pipe  85  for guiding water discharged from the drain pump  81  to the outside of the cabinet  2 . In some implementations, the second drain pipe  85  may be a corrugated pipe. 
     Because the laundry treatment apparatus  100  is configured such that the drawer  3  can be discharged from the cabinet  2 , it is necessary to prevent the drawer  3  from colliding with the cabinet  2  and to prevent the drawer  3  from being discharged from the cabinet  2  during transportation of the laundry treatment apparatus  100 . 
     In order to prevent the drawer  3  from colliding with the cabinet  2  and to prevent the drawer  3  from being discharged from the cabinet  2  during transportation, the laundry treatment apparatus  100  further includes a spacer, which is separably coupled in a space between the drawer  3  and the cabinet  2 . 
     The spacer may include at least one of a first spacer located in the space between the upper surface of the drawer  3  and the cabinet  2 , and a second spacer located in the space between the bottom surface of the drawer  3  and the cabinet  2 . 
     Although the first spacer and the second spacer are interference-fitted in the space between the drawer  3  and the cabinet  2  so as to fix the drawer  3  to the cabinet  2  during transportation, the first spacer and the second spacer may be discharged to the outside of the cabinet  2  through holes formed in the upper surface and the bottom surface of the cabinet  2  after transportation is completed. 
     Because the tub  4  is supported inside the drawer  3  via the tub support unit  6 , the laundry treatment apparatus  100  needs to prevent not only the unwanted discharge of the drawer  3  from the cabinet  2 , but also the collision of the tub  4  and the drawer  3  during transportation. 
     To solve the problems described above, the first spacer may be provided so as to prevent the tub  4  from colliding with the drawer  3  during transportation of the laundry treatment apparatus  100 , and the second spacer may be provided so as to prevent the drawer  3  from being discharged from the cabinet  2  during transportation of the laundry treatment apparatus  100 . 
     That is, as illustrated in  FIG. 6 , the first spacer  27  may be provided so as to maintain the distance between the cabinet  2  and the door  45 , and may be separated from the space between the cabinet  2  and the door  45  through an upper through-hole  23  (formed in the upper surface of the cabinet  2 ). 
     The second spacer  29  may be provided to maintain the distance between the cabinet  2  and the bottom surface of the drawer  3 , and may be separated from the space between the cabinet  2  and the bottom surface of the drawer  3  through a lower through-hole  25  (formed in the bottom surface of the cabinet  2 ). 
     The first spacer  27  may be formed of any material so long as it can maintain the distance between the cabinet  2  and the door  45 . For example, the first spacer  27  may be formed of an elastic material, such as sponge. 
     The first spacer  27  may be interference-fitted in the space between the upper surface of the door  45  and the cabinet  2 , and may be discharged from the inside of the cabinet  2  to the outside of the cabinet  2  through the upper through-hole  23 . 
     The second spacer  29  may also be formed of an elastic material, such as sponge. The second spacer  29  may be interference-fitted in the space between the bottom surface of the drawer  3  and the cabinet  2 . 
     The second spacer  29  may be inserted to the inside of the cabinet  2  from the outside of the cabinet  2 , or may be discharged from the inside of the cabinet  2  to the outside of the cabinet  2 , through the lower through-hole  25 . 
     The laundry treatment apparatus  100  may further include an upper through-hole door  231  separably coupled to the cabinet  2  for opening and closing the upper through-hole  23 . This serves to prevent impurities from entering the cabinet  2  through the upper through-hole  23  during transportation of the laundry treatment apparatus  100 . 
     In some implementations, the laundry treatment apparatus  100  may further include a lower through-hole door for opening and closing the lower through-hole  25 . 
       FIGS. 7 and 8  illustrate example spacers. In  FIG. 7 , the second spacer  29  has the feature of being inserted into the space between the rotor M 2  and the bottom surface of the drawer  3  so as to prevent the tub  4  from moving inside the drawer  3  during transportation of the laundry treatment apparatus  100 . 
     That is, the laundry treatment apparatus of  FIG. 7  further includes a drawer through-opening  313  formed in the bottom surface of the drawer  3  so as to be located under the rotor M 2 . The second spacer  29  may have the feature of being interference-fitted in the space between the rotor M 2  and the bottom surface of the drawer  3  through the lower through-hole  25  and the drawer through-opening  313 . 
     In some implementations, likewise, a lower through-hole door for opening and closing the lower through-hole  25  may be separably coupled to the bottom surface of the cabinet  2 , or a drawer through-opening door for opening or closing the drawer through-opening  313  may be separably coupled to the bottom surface of the drawer  3 . 
     In  FIG. 8 , the second spacer  29  has the feature of including a support body  291  for supporting the bottom surface of the cabinet  2  and a fixing body  293  protruding from the support body  291  so as to support the rotor M 2  for minimizing the movement of the tub  4 . 
     The support body  291  may be provided so as to support the bottom surface of the cabinet  2 , e.g. the bottom surface of the entire laundry treatment apparatus  100 . The fixing body  293  is inserted into the lower through-hole  25  and the drawer through-opening  313  so as to support the rotor M 2 . In some implementations, once the laundry treatment apparatus  100  has been seated on the support body  291 , some implementations may prevent the tub  4  from moving inside the drawer  3  and may also prevent the drum  3  from moving inside the tub  4  during transportation. 
     In some implementations, the drawer through-opening  313  may be an opening formed in the bottom surface of the drawer  3 . However, when the bottom surface of the drawer  3  is open, the drawer through-opening  313  may be replaced with the open bottom surface of the drawer  3 . 
     In addition, the fixing body  293  may be inserted into the lower through-hole  25  and the drawer through-opening  313  so as to support the bottom surface of the tub  4 . 
     As is apparent from the above description, the laundry treatment apparatus may prevent a drawer from colliding with a cabinet or from being discharged from the cabinet during transportation of the laundry treatment apparatus. 
     The laundry treatment apparatus may prevent a drawer from colliding with a cabinet or from being discharged from the cabinet during transportation using a device that is separable from the cabinet after transportation. 
     The laundry treatment apparatus may prevent a drum from moving inside a tub during transportation. 
     The laundry treatment apparatus may effectively control vibration of a tub in which laundry is received.
