The operation of the fabric treatment apparatus of the exemplary embodiment of FIGS. 1 and 2 will hereinafter be described in detail.
The user may open the door 20, may hang up the hangers 30 where clothes are hung up on the clothes rack 130, may shut the door 20, and may operate the fabric treatment apparatus.
Then, the heating unit 120 may supply hot air and/or steam into the treatment room 110 according to the type of operating mode of the fabric treatment apparatus. The heating unit 120 may heat air sucked out of the treatment room 110 via the air outlet 121a, and may inject the heated air into the treatment room 110 via the hot air inlet 121b. In addition, the heating unit 120 may spray steam into the treatment room 110 via the steam injection hole 122.
When the heating unit 120 supplies hot air and/or steam into the treatment room 110, the motor 140 may rotate the circular plate 162 by generating rotation force outside the treatment room 110. When the circular plate 162 rotates, the eccentric pin 164 may rotate eccentrically, and the contact unit 170, which is slidably coupled to the eccentric pin 164, may move reciprocally in a linear path. Then, the clothes rack 130, which is coupled to the contact unit 170, may move reciprocally in a longitudinal direction thereof.
Then, the hangers 30 on the clothes rack 130 may also move reciprocally in a linear path and may thus be able to move the clothes thereon. In this manner, it is possible to improve the efficiency of treatment of the clothes on the hangers 30 with the hot air and/or the steam supplied by the heating unit 120.
FIG. 3 illustrates a partial perspective view of a fabric treatment apparatus according to another exemplary embodiment of the present invention, and FIG. 4 illustrates a contact unit of the fabric treatment apparatus of the exemplary embodiment of FIG. 3. Referring to FIGS. 3 and 4, a clothes rack 130 may be able to slide toward the direction in which the treatment room 110 is open, and the contact unit 170 may include a guide 174 which can be attached to or detached from an eccentric pin 164 and enables the eccentric pin 164 to be slid into a slot 172 of the contact unit 170.
When a door 20 is open, the clothes rack 130 may slide toward the direction in which the treatment room 110 is open. The clothes rack 130 may be configured to move in various manners, other than that set forth herein. Connectors 150 may be rotatably coupled to a ceiling 111 of the treatment room 110, or the clothes rack 130 may be rotatably coupled to the connectors 150 and may thus be able to slide toward the direction in which the treatment room 110 is open.
When the clothes rack 130 slides out of the treatment room 110, the contact unit 170 may be detached from an eccentric unit 160 including the eccentric pin 164 and a circular plate 162. More specifically, when the clothes rack 130 slides out of the treatment room 110, the eccentric pin 164 may be disengaged from the slot 172 of the contact unit 170. On the other hand, when the clothes rack 130 slides back into the treatment room 110, the eccentric pin 164 may be inserted into the slot 172 and may thus be slidably coupled to the contact unit 170.
The contact unit 170 may include the guide 174, which guides the eccentric pin 164 of the eccentric unit 160 into the slot 172 of the contact unit 170 when the clothes rack 130 slides into the treatment room 110. The guide 174 may be implemented in various manners. In the exemplary embodiment of FIGS. 3 and 4, the guide 174 may be formed as a funnel and may extend from the slot 172 of the contact unit 170. Even when the eccentric pin 164 is disposed eccentrically with respect to the slot 172, the eccentric pin 164 may be guided into the slot 172 by the guide 174.
The operation of the fabric treatment apparatus of the exemplary embodiment of FIGS. 3 and 4 is almost the same as the operation of the fabric treatment apparatus of the exemplary embodiment of FIGS. 1 and 2 and thus will hereinafter be described in detail, focusing mainly on differences with the operation of the fabric treatment apparatus of the exemplary embodiment of FIGS. 1 and 2.
The user may open the door 20, and may slide the clothes rack 130 out of the treatment room 110. Thereafter, the user may hang up a number of hangers 30 where clothes are hung up on the clothes rack 130, and may slide the clothes rack 130 back into the treatment room 110. When the clothes rack 130 slides into the treatment room 110, the eccentric pin 164 may be guided into the slot 172 by the guide 174, which is funnel-shaped, and may thus be slide into the slot 172. Thereafter, the user may shut the door 20 and may operate the fabric treatment apparatus.
FIG. 5 illustrates a contact unit of a fabric treatment apparatus according to another exemplary embodiment of the present invention, and FIG. 6 illustrates an eccentric unit of the fabric treatment apparatus of the exemplary embodiment of FIG. 5. Referring to FIGS. 5 and 6, a clothes rack 130 may slide out toward the direction in which a treatment room 110 is open. A contact unit 170 can be attached to or detached from an eccentric pin 164, and may include a guide 176 which enables the eccentric pin 164 to be slid into a slot 172 of the contact unit 170.
The guide 176 may be formed as a slot. The guide 176 may be disposed above the slot 172 and may be wider than the slot 172. The eccentric pin 164 may include an elastic element 164a which is rotatably coupled to a circular plate 162.
When the eccentric unit 160 is detached from the contact unit 170 and then attached back to the contact unit 170, the eccentric pin 164 may be placed in contact with the guide 176 first if the eccentric pin 164 is disposed eccentrically with respect to the slot 172. In this case, the elastic element 164a of the eccentric pin 164 may contract. Then, when a motor 140 generates rotation force and thus the circular plate 162 rotates, the eccentric pin 164 may rotate inside the guide 176 and may then be slid into the slot 172 by the elastic force of the elastic element 164a. 
According to the present invention, since a clothes rack on which a number of hangers are hung up moves reciprocally inside a fabric treatment apparatus in a linear path, it is possible to improve the efficiency of treating clothes on the hangers. In addition, since the clothes rack can slide out of the fabric treatment apparatus, it is easy to hang up hangers on the clothes rack.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
