Abstract

This disclosure relates to a clothing treatment device comprising: a cabinet having a first lateral panel and a second lateral panel which are disposed so as to face each other, an upper panel and a lower panel which connect the first lateral panel and the second lateral panel and respectively form the upper surface and the floor surface, a first rear panel which connects the first lateral panel, the second lateral panel and the upper panel and forms the rear surface, and a second rear panel which connects the first lateral panel and the second lateral panel and is positioned below the first rear panel; a first base having a front panel which is fixed to the first lateral panel, the second lateral panel, the upper panel and the lower panel and forms the front surface of the cabinet and an input port which is provided through the front panel.

First claim

What is claimed is:

1. A laundry treating apparatus comprising:
a cabinet including:
a first side panel and a second side panel opposite to each other;
a top panel and a bottom panel connecting the first side panel and the second side panel to each other and defining top and bottom surfaces of the cabinet, respectively;
a first rear panel connecting the first side panel, the second side panel, and the top panel to each other and defining a rear surface of the cabinet; and
a second rear panel connecting the first side panel and the second side panel to each other, wherein the second rear panel is positioned below the first rear panel;

a first base including:
a front panel fixed to the first side panel, the second side panel, the top panel, and the bottom panel and defining a front surface of the cabinet; and
a laundry inlet extending through the front panel;

a first chamber fixed to the front panel and disposed inside the cabinet, the first chamber including a bottom surface in which a chamber through-hole is formed, wherein the first chamber has a laundry receiving space defined therein communicating with the laundry inlet;
a second base including:
a front frame disposed between the front panel and the second rear panel;
a top frame extending from the front frame toward the second rear panel and spaced apart from a bottom surface of the first chamber, and having a fixing hole;
a first side frame spaced apart from the first side panel; and
a second side frame spaced apart from the second side panel;

a second chamber defined by the front frame, the top frame, the first side frame, the second side frame, the bottom panel, and the second rear panel;
a receiving body disposed inside the second chamber wherein the receiving body is able to be withdrawn out of the second chamber;
a flow channel defining portion disposed between the bottom surface of the first chamber and the top frame, and configured to communicate with the fixing hole and the chamber through-hole;
a supply unit received in the receiving body and disposed inside the second chamber, the supply unit being connected to the fixing hole, and the supply unit being configured to supply at least one of air or moisture to the first chamber; and
a foam plastic inserted into a foam space defined between the cabinet, the first base, the first chamber, and the second base.

2. The apparatus of claim 1 , wherein the apparatus further comprises:
a first spacer disposed on the first side frame to maintain a spacing between the first side frame and the first side panel; and
a second spacer disposed on the second side frame to maintain a spacing between the second side frame and the second side panel.

3. The apparatus of claim 2 , wherein the first spacer includes:
a first rear-panel supporting portion protruding from a rear surface of the first side frame toward the first side panel so that the second rear panel is fixed to the first rear-panel supporting portion;
a first bottom-panel supporting portion protruding from a bottom surface of the first side frame toward the first side panel such that the bottom panel is fixed to the first bottom-panel supporting portion;
a first frame rear fastener disposed on the first rear-panel supporting portion and fixed to a rear surface of the first side panel; and
a first frame bottom fastener disposed on the first bottom-panel supporting portion and fixed to a bottom surface of the first side panel,
wherein the second spacer includes
a second rear-panel supporting portion protruding from a rear surface of the second side frame toward the second side panel such that the second rear panel is fixed to the second rear-panel supporting portion;
a second bottom-panel supporting portion protruding from a bottom surface of the second side frame toward the second side panel such that the bottom panel is fixed to the second bottom-panel supporting portion;
a second frame rear fastener disposed on the second rear-panel supporting portion and fixed to a rear surface of the second side panel; and
a second frame bottom fastener disposed on the second bottom-panel supporting portion and fixed to a bottom surface of the second side panel.

4. The apparatus of claim 2 , wherein the chamber through-hole comprises a first chamber through-hole and a second chamber through-hole formed through the bottom surface of the first chamber,
wherein the fixing hole comprises a first fixing hole and a second fixing hole formed through the top frame,
wherein the flow channel defining portion comprises:
a first flow channel defining portion connecting the first chamber through-hole and the first fixing hole to each other; and
a second flow channel defining portion connecting the second chamber through-hole and the second fixing hole to each other, and

wherein the supply unit includes:
a circulation duct fixedly received in the receiving body to connect the first fixing hole and the second fixing hole to each other;
a first heat exchanger for dehumidifying air introduced into the circulation duct;
a second heat exchanger disposed inside the circulation duct to heat air passing through the first heat exchanger; and
a fan for moving air introduced into the first fixing hole to the second fixing hole.

5. The apparatus of claim 4 , wherein the apparatus further comprises:
a third chamber through-hole extending through a bottom surface of the first chamber;
a supply pipe through-hole extending through the top frame;
wherein the supply unit includes:
a steam generator installed inside the second chamber to generate steam;
a spray body having a spray hole defined therein communicating with the third chamber through-hole and a supply pipe inserted in the supply pipe through-hole; and
a connection pipe connecting the steam generator and the supply pipe to each other.

6. The apparatus of claim 5 , wherein the apparatus further comprises accommodating portions formed by bending a top frame toward a bottom surface of the first chamber to provide a space for accommodating therein the supply pipe,
wherein the supply pipe through-hole extends through a top surface of the accommodating portions.

7. The apparatus of claim 5 , wherein the apparatus further comprises:
a receiving groove recessed in the front panel toward the front frame;
a second chamber communication hole extending through the receiving groove;
a receiving-groove communication hole extending through the front frame and connected to the second chamber communication hole;
a drainage tank having a water storage space defined therein and removably received in the receiving groove;
a drainage tank through-hole extending through the drainage tank and communicating with the second chamber communication hole;
a first discharge pipe coupled to the drainage tank through-hole when the drainage tank is inserted into the receiving groove, wherein the first discharge pipe is separated from the drainage tank through-hole when the drainage tank is withdrawn out of the receiving groove; and
a discharge pump for supplying condensate water discharged from the first heat exchanger to the first discharge pipe.

8. The apparatus of claim 7 , wherein the apparatus further comprises:
a water supply tank having a water storage space defined therein and removably received in the receiving groove;
a water supply tank through-hole extending through the water supply tank and communicating with the second chamber communication hole;
a first supply pipe coupled to the water supply tank through-hole when the water supply tank is inserted into the receiving groove, wherein the first supply pipe is separated from the water supply tank through-hole when the water supply tank is withdrawn out of the receiving g
