Therefore, the wheel  339  becomes a means for preventing the drawer panel  33  from being in contact with a ground when the drawer  3  is ejected from or inserted into the cabinet  2 . 
         [0036]    The drawer cover  35  is provided with a first through hole  353 , which is provided to pass through the drawer cover  35 . The first through hole  353  enables communication between inside of the drawer body  31  and outside of the drawer body  31 . The drawer cover  35  also is provided with a second through bole  355 , which is provided to pass through the drawer cover  35  and into which a water supply pipe  73  is inserted. 
         [0037]    As shown in  FIG. 2 , the receiving portions  4  and  5  provided inside the drawer  3  may include a tub  4  provided inside the drawer body  31 , providing a space where washing water is stored, and a drum  5  rotatably provided inside the tub  4 , storing laundry therein. 
         [0038]    The tub  4  is fixed into the drawer  3  by a tub support unit  48 . The tub support unit  48  is a means for connecting a circumferential surface of the tub  4  with the drawer  3 , and may be provided with a means for attenuation of vibration. 
         [0039]    On an upper surface of the tub  4 , an inlet  46  communicating the inside of the tub  4  with the outside of the tub  4 , a door  49  opening or closing the inlet  46 , and a water supply unit  47  supplying washing water to the tub  2  are provided. 
         [0040]    The door  49  is rotatably provided on the upper surface of the tub  4  (to open or close a part of the tipper surface of the tub), and may be rotated without interfering with the drawer cover  35  through the first through hole  353 . Therefore, a user may insert laundry into the tub  4  by opening the door  49  after ejecting the drawer  3  from the cabinet  2 . 
         [0041]    The drum  5  may be provided in a cylindrical shape of which upper surface is opened, and may be rotated inside the tub  4  by means of a drum driver  6  provided outside the tub  4 . 
         [0042]    The drum driver  6  may include a stator  61  fixed to the tub  4 , forming a rotating magnetic field, and a rotor  63  rotated by the rotating magnetic field. The rotor  63  is connected with a driving shaft  53  fixed to the bottom of the drum  5  by passing through the tub  4 . As shown, the driving shaft  53  may be provided to be orthogonal to the bottom of the drawer  3 . 
         [0043]    A drum through hole  51  is provided on the outer circumference of the drum  5  to communicate the inside of the drum  5  with the inside of the tub  4 . 
         [0044]    The receiving portions are provided as the tub  4  and the drum  5  to allow the first treating apparatus L to perform a washing function. Therefore, in order that the first treating apparatus L may also perform a drying function of laundry, a hot-air supply unit supplying the hot air to the tub  2  is further provided inside the cabinet  2 . 
         [0045]    Since the hot-air supply unit provided in the first treating apparatus L may be provided in the same manner as the second hot-air supply unit described as above, its detailed description will be omitted. 
         [0046]    In some implementations, if the first treating apparatus  1 , is provided to perform only a drying function of laundry, the drum  5  is only provided as the receiving portion, and the hot-air supply unit provided in the first treating apparatus should be provided to supply the hot air to the drum  5 . 
         [0047]    The first treating apparatus L is connected with a water supply source located outside the laundry treating apparatus  100  through a water supply unit  7 . The water supply unit  7  may include a water supply pipe  71  connecting the water supply source with the water supply unit  47 , and a valve  73  opening or closing the water supply pipe  71 . 
         [0048]    The washing water stored in the tub  4  is discharged to the outside of the cabinet  2  through a drainage unit  8 . The drainage unit  8  may include a drainage pipe  83  guiding the washing water inside the tub  4  to the outside of the cabinet  2 , and a pump  81  (controlled by a controller) discharging the washing water inside the tub  4  to the drainage pipe  83 . 
         [0049]    Since the drum driver  6  is fixed to the tub  4  and the tub  4  is fixed to the drawer  3  through the tub support unit  48 , the first treating apparatus L may deliver, to the drawer  3 , vibration generated by the drum or the tub when the drum  5  is rotated by the drum driver  6 . 
         [0050]    If vibration of the drum  5  or the tub  4  is delivered to the drawer  3 , noise or vibration may be generated by collision between the drawer  3  and the cabinet  2 , and the drawer  3  may be ejected from the cabinet  2  during rotation of the drum driver  6 . 
         [0051]    To solve this problem, the laundry treating apparatus  100  may further include a detachable portion  9  that minimizes vibration of the drawer  3  inside the cabinet  2  as well as prevents the drawer  3  from being ejected from the cabinet  2 . 
         [0052]    The detachable portion  9  includes fastening units  911  and  913  provided to perform a reciprocating motion along any one of a height direction and a width direction of the drawer.

         [0059]    As shown in  FIGS. 4( a ) and 4( b ) , the feeding unit  95  may include a feeding body  951  that may perform a reciprocating motion along the height direction Y of the drawer  3 , a first slot  953  provided in the feeding body  951  and connected with the first bar  911 , and a second slot  955  provided in the feeding body  951  and connected with the second bar  913 . 
         [0060]    The drawer  3  may be provided with a guider  99  providing a moving path of the feeding body  951 .  FIGS. 4( a ) and 4( b )  illustrate examples where the guider  99  is provided to support both sides of the feeding body  951 . 
         [0061]    The first slot  953  is a means (means for moving the first bar  911 ) pushing or pulling the first coupling unit  912  provided in the first bar, wherein the first coupling unit  912  is connected with the feeding body  951  by being inserted into the first slot  953 . 
         [0062]    The first slot  953  may be provided to be inclined at a predetermined angle with respect to a straight line (reference line K 1 ) parallel with a moving direction of the feeding body  951  as well as to have a certain length along a motion direction (Y-axis direction, height direction of the feeding body) of the feeding body  951 . 
         [0063]    That is, the first slot  953  may be provided to be inclined at an angle K 2  greater than 0° and smaller than 90° with respect to the reference K 1 . This is to move the first bar  911  by changing the position of the feeding body  951 . 
         [0064]    The second slot  955  is a means (means for moving the second bar  913 ) pushing or pulling the second coupling unit  914  provided the second bar, wherein the second coupling unit  914  is connected with the feeding body  951  by being inserted into the second slot  955 . 
         [0065]    The second slot  955  may also be provided to be inclined at a predetermined angle with respect to the reference line K 1  as well as to have a predetermined length along a motion direction of the feeding body  951 . In this case, the first slot  953  and the second slot  955  are provided to form axial symmetry based on the reference line K 1 . 
         [0066]    A first direction is set to a moving direction of the feeding body  951  in which an interval between the first coupling unit  912  and the second coupling unit  914  is widened, and a second direction is set to a moving direction of the feeding body  951  in which an interval between the first coupling unit  912  and the second coupling unit  914  becomes narrow. In this case, the first slot  953  and the second slot  955  fix the free end F 1  of the first bar and the free end F 2  of the second bar to the cabinet  2  if the feeding body  951  moves to the first direction, and detach the free end of the first bar and the free end F 2  of the second bar from the cabinet  2  if the feeding body  951  moves to the second direction. 
         [0067]      FIG. 4  illustrates an example where that an upper end of the first slot  953  is connected with that of the second slot  955  and a lower end of the first slot  953  is detached from that of the second slot  955 . 
         [0068]    Unlike  FIGS. 4( a ) and 4( b ) , the first slot and the second slot may be provided in such a manner that the upper end of the first slot  953  is detached from that of the second slot  955  and the lower end of the first slot  953  is also detached from that of the second slot  955 . In this ease, a distance between the upper end of the first slot  953  and the upper end of the second slot  955  may be shorter than a distance between the lower end of the first slot  953  and the lower end of the second slot  955 . 
         [0069]    If the first coupling unit  912  and the second coupling unit  914  are respectively located on the upper ends (a point where the interval between the slots is minimum and a point where the distance between the first coupling unit and the second coupling unit is minimum) of the first slot  953  and the second slot  955 , the free end F 1  of the first bar and the free end F 2  of the second bar may respectively be detached from the first receiving body  931  and the second receiving body  935 . 
         [0070]    In sonic implementations, if the first coupling unit  912  and the second coupling unit  914  are respectively located on the lower ends (a point where the interval between the slots is maximum and a point where the distance between the first coupling unit and the second coupling unit is maximum) of the first slot  953  and the second slot  955 , the free end F 1  of the first bar and the free end F 2  of the second bar may respectively be coupled to the first receiving body  931  and the second receiving body  935 . 
         [0071]    Therefore, in  FIGS. 4( a ) and 4( b ) , a direction (direction that the upper end of each slot is located) that the distance between the first slot  953  and the second slot  955  becomes short becomes the first direction, and a direction (direction that the lower end of each slot is located) that the distance between the first slot  953  and the second slot  955  becomes increased becomes the second direction. 
         [0072]    Unlike  FIGS. 4( a ) and 4( b ) , the distance between the upper end of the first slot  953  and the upper end of the second slot  955  may be longer than the distance between the lower end of the first slot  953  and the lower end of the second slot  955 . 
         [0073]    Even in this case, if the feeding body  951  moves to the first direction that the interval between the respective bars  911  and  913  is widened, the free end F 1  of the first bar and the free end F 2  of the second bar may be fixed to the cabinet  2 . If the feeding body  951  moves to the second direction that the interval between the respective bars  911  and  913  becomes narrow, the free end F 1  of the first bar and the free end F 2  of the second bar may be detached from the cabinet  2 . 
         [0074]    That is, if the first coupling unit  912  and the second coupling unit  914  are respectively located on the upper ends of the first slot  953  and the second slot  955 , the free end F 1  of the first bar and the free end F 2  of the second bar may respectively be coupled to the first receiving body  931  and the second receiving body  935 . If the first coupling unit  912  and the second coupling unit  914  are respectively located on the lower ends of the first slot  953  and the second slot  955 , the free end F 1  of the first bar and the free end F 2  of the second bar may respectively be detached from the first receiving body  931  and the second receiving body  935 . 
         [0075]    The aforementioned feeding unit  95  may perform a reciprocating motion along the height direction Y of the drawer through the driving unit  97  provided in the drawer  3 . The driving unit  97  may include a motor  971  fixed to the drawer  3 , and a transform unit  975  transforming a rotation power of the motor  971  to a reciprocating power of the feeding body  951 . 
         [0076]    The transform unit  975  may include a body slot  976  provided along the width direction X of the feeding body  951 , an arm  977  coupled to a rotational axis  973  of the motor  971 , and a slot connecting unit  979  connecting the arm  977  with the body slot  976 . 
         [0077]    The arm  977  is rotated by the rotational axis  973  of the motor, and the slot connecting unit  979  is extended from the arm  977 , whereby the slot connecting unit  979  may be rotated with a circular tracking having a certain diameter L 2  during operation of the motor  971 . 
         [0078]    In some implementations, the body slot  976  is provided along the direction X vertical to the motion direction Y of the feeding body  951 , and has a length L 1  the same as or longer than the diameter L 2  of the circular tracking formed by the slot connecting unit  979 . 
         [0079]    Therefore, a rotation motion of the motor rotational axis  973  is transformed to a straight-line reciprocating motion of the feeding body  951  by the transform unit  975 , and the feeding body  951  performs a reciprocating motion along the height direction Y of the drawer  3  under the guide of the guider  99 . 
         [0080]    Hereinafter, the operation process of the detachable portion  9  having the aforementioned structure will be described with reference to  FIGS. 3( a ) to 5( b ) . 
         [0081]    If the body slot  976  is located at a position lower than the rotational axis  973  of the motor  971  in accordance with the operation of the motor  971  (the states of  FIGS. 4( a ) and 4( b )  that the first coupling unit  912  is located on the upper end of the first slot  953  and the second coupling unit  914  is located on the upper end of the second slot  955 ), each of the first bar  911  and the second bar  913  moves toward the feeding body  951 . Therefore, the free end F 1  of the first bar is detached from the first receiving body  931 , and the free end F 2  of the second bar is detached from the second receiving body  935  (see  FIGS. 3( a ) and 3( b ) ). 
         [0082]    If the free end F 1  of the first bar and the free end F 2  of the second bar are respectively detached from the respective receiving bodies  931  and  935 , since coupling between the drawer  3  and the cabinet  2  is released, the user may eject or insert the drawer  3  from or into the cabinet  2 . 
         [0083]    In some implementations, if the rotational axis  973  of the motor is rotated by a controller, the feeding body  951  moves toward the upper end of the drawer  3  along the guider  99 . If the body slot  976  moves to the position higher than the rotational axis  973  in accordance with the ascending movement of the feeding body  951 , the fastening units  911  and  913  becomes a state of  FIG. 5( a ) . 
         [0084]    That is, if the body slot  976  moves to the position higher than the rotational axis  973 , each of the free end F 1  of the first bar and the free end F 2  of the second bar moves toward a direction far away from the feeding body  951  (the first bar and the second bar move to be far away from each other). 
         [0085]    If the free ends F 1  and F 2  of the respective bars move toward the direction far away from the feeding body  951 , the free end F 1  of the first bar is coupled to the first receiving body  931 , and the free end F 2  of the second bar is coupled to the second receiving body  933 , whereby the drawer  3  is fixed to the cabinet  2 . 
         [0086]    As shown in  FIG. 2 , the tub support unit  48  provided in the first treating apparatus L connects the outer circumference of the tub  4  with the drawer  3 . Therefore, the tub  4  may be vibrated inside the drawer  3  during rotation of the drum  5 , and if vibration of the tub  4  is delivered to the drawer  3 , the drawer  3  may be ejected from the cabinet  3 . However, since the detachable portion  9  fixing the drawer to the cabinet is provided, the aforementioned problem is solved. 
         [0087]    However, in the laundry treating apparatus  100  having the aforementioned structure, if the driving unit  97  is out of order in a state that the drawer  3  is fixed to the cabinet  2 , a problem occurs in that it is difficult to eject the drawer  3  from the cabinet  2 . 
         [0088]    To solve this problem, the laundry treating apparatus  100  may further include an unlocking unit  98  for allowing the drawer  3  fixed to the cabinet  2  to be ejected from the cabinet  2 . 
         [0089]    The unlocking unit  98  is operated independently from the driving unit  97 , and may be implemented in various structures for enabling the aforementioned function.  FIGS. 6( a ) and 6( b )  illustrate examples of an unlocking unit  98  that enables one-way movement of the feeding body  951 . That is, the unlocking unit  98  of  FIGS. 6( a ) and 6( b )  may include a handle  983  detachable from the drawer  3  and a wire  981  connecting the feeding body  951  with the handle  983 . 
         [0090]    The handle  983  may be fixed to the outer circumference of the drawer  3  through a handle support unit  336  provided in the drawer  3 . The handle support unit  336  may be provided on the bottom of the drawer panel  33 . In this case, a panel through hole  338 , through which the wire  981  passes, should be provided on the bottom of the drawer panel  33 . 
         [0091]    As shown in  FIG. 7 , the handle  983  may include a handle body  985  inserted into the handle support unit  336 , and an ejecting unit  987  ejecting the handle body  985  from the handle support unit  336 , wherein one end of the wire  981  is fixed to the handle body  985 . 
         [0092]    The ejecting unit  987  may be implemented in various mariners as far as the handle body  985  may be ejected from the handle support unit  336 . In  FIG. 7 , the ejecting unit  987  may include a plate  987   a  provided to be extended from the handle body  985 , a protrusion  987   b  protruded from the plate  987   a,  and a pressurizing request unit  987   c  located between a free end of the plate  987   a  and the protrusion  987   b.    
         [0093]      FIG. 7  illustrates that the protrusion  987   b  is in contact with the bottom of the drawer panel  33 . In this case, the protrusion  987   b  may be protruded at a length, which may be in contact with the bottom of the drawer panel if the handle body  985  is inserted into the handle support unit  336 . 
         [0094]    In some implementations, if the protrusion  987   b  is provided in contact with the handle support unit  336 , the protrusion  987   b  should be protruded at a length that may be in contact with the handle support unit  336  if the handle body  985  is inserted into the handle support unit  336 . 
         [0095]    Once the pressurizing request unit  987   c  is pushed, since the handle body  985  is rotated around the protrusion  987   b,  the user may eject the handle body  985  from the handle support unit  336 . 
         [0096]    If the free end F 1  of the first bar and the free end F 2  of the second bar are respectively coupled to the first receiving body  931  and the second receiving body  935 , the drawer  3  is fixed to the cabinet  2  (the state that the drawer is not ejected from the cabinet). 
         [0097]    In this state, if the user pulls the wire  981  toward the second direction by using the handle  983 , the feeding body  951  will move toward the bottom of the drawer panel  33 . 
         [0098]    As described above, the second direction means a moving direction of the feeding body  951 , which makes the interval between the first coupling unit  912  and the second coupling unit  914  narrow. In  FIG. 7 , the direction (the direction that the wheel  339  is located) that the bottom of the drawer panel  33  is located becomes the second direction. 
         [0099]    If the feeding body  951  moves toward the bottom of the drawer panel  33 , since the free end F 1  of the first bar and the free end F 2  of the second bar are respectively detached from the first receiving body  931  and the second receiving body  935 , the aforementioned unlocking unit  98  may release the state that the drawer  3  is fixed to the cabinet  2 , regardless of the operation of the driving unit  97 . 
         [0100]    Since the feeding body  951  is connected to the handle body  985  through the wire  981 , the unlocking unit  98  moves the feeding body  951  in a second direction only. That is, the unlocking unit  98  fails to move the feeding body  951  in a first direction. 
         [0101]    In some implementations, if the drawer  3  is fixed to the cabinet  2  by the fastening units  911  and  913 , an angle A between the straight line K 1  (reference line parallel with the moving direction of the feeding body  951  and the arm  977  should be greater than 0° and smaller than 180°. 
         [0102]    With an angle outside of the range between 0° and 180°, the user may have difficulty in moving the feeding body  951  in a second direction or cannot move the feeding body  951  in a second direction due to the slot connecting unit  979  provided in the arm  977 . In this case, even though the user pulls the handle body  985 , if the angle between the reference line K 1  and the arm  977  is 0° or 180°, the drawer  3  may remain in a state where the drawer  3  is fixed to the cabinet  2 . 
         [0103]    Therefore, the controller C (see  FIGS. 6( a ) and 6( b ) ) controls a rotational angle of the rotational axis  973  provided in the motor  971  so that the angle between the reference line K 1  and the arm  977  may not be 0° or 180° when the feeding body  951  completely moves to the first direction. 
         [0104]    Unlike  FIGS. 3 to 7 , the fastening units  911  and  913  may be provided to perform a reciprocating motion along the height direction Y of the drawer  3 , and the feeding unit  95  may be provided to perform a reciprocating motion along the width direction X of the drawer  3 . 
         [0105]    That is, the first bar  911  may be provided to perform a reciprocating motion along the height direction of the drawer  3  and connects the upper surface of the drawer  3  with the upper surface of the cabinet  2 . The second bar  913  may be provided to perform a reciprocating motion along the height direction of the drawer  3  and connects the lower surface of the drawer  3  with the lower surface of the cabinet  2 . The feeding body  951  may be provided to perform a reciprocating motion along the width direction of the drawer  3 . 
         [0106]    Even in this case, the first slot  953  and the second slot  955  may be provided in such a manner that the free end F 1  of the first bar and the free end F 2  of the second bar may be fixed to the cabinet  2  if the feeding body  951  moves to the first direction that the interval between the respective bars  911  and  913  is widened. The free end F 1  of the first bar and the free end F 2  of the second bar may be detached from the cabinet  2  if the feeding body  951  moves to the second direction that the interval between the respective bars  911  and  913  becomes narrow.
