When the hanger 36 is moved forward, the nose 373b of the cam 373 may project forward from the base circle 373a of the cam 373. When the hanger 36 is moved forward, the nose 373b of the cam 373 comes into contact with the cam contactor 368 (see FIG. 12) disposed on the power transmission rod 362e, and the cam contactor 368 can be pushed forward. When the cam 373 pushes the cam contactor 368 forward, the sliding body 369 moving integrally with the cam contactor 368 can move forward. When the cam 373 pushes the cam contactor 368 forward, the gap between the sliding body 369 and the door 31 may be reduced. At this time, as the distance between the sliding body 369 and the door 31 becomes closer, the spring 367 may be compressed, and the spring 367 may have a first length L1.

When the hanger 36 is moved backward, the nose 373b of the cam 373 may project backward from the base circle 373a of the cam 373. When the hanger 36 moves backward, the nose 373b of the cam 373 can release contact with the cam contactor 368 (see FIG. 12) disposed on the power transmission rod 362e. When contact between the cam 373 and the cam contactor 368 is released, the sliding body 369 can be moved backward by the restoring force of the spring 367 . The spring 367 can be compressed forward when the cam 373 is in contact with the cam contactor 368, and has an original length when the cam 373 releases contact with the cam contactor 368. can be restored with When the sliding body 369 is moved backward by the restoring force of the spring 367, the distance between the sliding body 369 and the door 31 may increase. At this time, the spring 367 may be restored to a second length L2 greater than the first length L1.

As described above, as the contact between the cam 373 and the hanger 36 is changed by the rotation of the shaft 371, the hanger 36 may reciprocate in the forward and backward directions. That is, when the cam 373 and the hanger 36 come into contact, the hanger 36 may move forward. When contact between the cam 373 and the hanger 36 is released, the hanger 36 may move backward. In a state in which the door 31 closes the opening 32, the hanger 36 may reciprocate in the forward and backward directions. By the back-and-forth reciprocating movement of the hanger 36, the clothes hanging on the hanger 36 can be shaken, and the sterilization and dehumidifying effect of the hot air supplied through the air supply duct 45 can be improved.

The above-described driving principle of the hanger 36 and operational effects according to the driving of the hanger 36 may be equally applied to both the upper hanger 36a and the lower hanger 36b.

Referring to FIG. 14 , the upper hanger 36a and the lower hanger 36b may move in opposite directions. The upper hanger 36a and the lower hanger 36b may reciprocate in directions crossing each other.

Referring to (a) of FIG. 14 , when the upper hanger 36a moves backward, the lower hanger 36b may move forward. When the upper hanger 36a is moved backward, the upper nose 373b can protrude toward the rear of the shaft 371 and can release contact with the upper hanger 36a. When the lower hanger 36b is moved forward, the lower nose 374b may protrude toward the front of the shaft 371 and come into contact with the lower hanger 36b to push the lower hanger 36b forward. have.

Referring to (b) of FIG. 14 , when the upper hanger 36a moves forward, the lower hanger 36b may move backward. When the upper hanger 36a is moved forward, the upper nose 373b may protrude toward the front of the shaft 371 and come into contact with the upper hanger 36a to push the upper hanger 36a forward. have. When the lower hanger 36b is moved rearward, the lower nose 374b may protrude toward the rear of the shaft 371 and may release contact with the lower hanger 36b.

The upper nose 373b and the lower nose 374b may protrude in opposite directions. Accordingly, the upper hanger 36a and the lower hanger 36b may move in opposite directions. The motor 375 may rotate the shaft 371 to change the protruding direction of the respective noses 373b and 374b, and depending on whether or not the contact between the noses 373b and 374b and the hangers 36a and 36b changes, the hanger (36a, 36b) can be reciprocated in the forward and backward directions.

As the upper hanger 36a and the lower hanger 36b reciprocate in opposite directions, vibration of the door 31 and the cabinet 30 may be reduced. As the phase of the vibration generated by the upper hanger 36a and the phase of the vibration generated by the lower hanger 36b are opposite, the vibration generated by each of the hangers 36a and 36b may be offset. For example, referring to the graph (c) of FIG. 14, P1 is the torque generated in the hangers 36a and 36b when the upper hanger 36a and the lower hanger 36b reciprocate in opposite directions ( T) is shown as a function of time. Since the phase of the vibration generated by the upper hanger 36a and the phase of the vibration generated by the lower hanger 36b are opposite, it can be confirmed that the magnitude of the torque T over time is constant. On the other hand, P2 indicates the magnitude of the torque T over time when only one of the upper hanger 36a and the lower hanger 36b reciprocates, and P3 indicates the upper hanger 36a and the lower hanger 36b It shows the magnitude of torque (T) over time when they reciprocate in the same direction. Comparing P2 with P1, the magnitude of the generated torque is small, but since only one of the two hangers is driven, there is a problem in that the sterilization and dehumidification effect on clothes is lowered, and since the magnitude of the torque changes over time, the vibration It can cause discomfort due to size change. Comparing P3 and P1, there is a problem in that the magnitude of the generated torque is amplified and the vibration becomes excessive, and the change range of the torque increases, causing discomfort due to the change in magnitude of the vibration.
