Abstract

The present disclosure relates to a clothing treatment apparatus comprising: a cabinet having a first side panel and a second side panel, an upper panel and a lower panel, and a rear panel; a first base having a front panel which is fixed to the first side panel, the second side panel, the upper panel, and the lower panel and forms a front surface of the cabinet, and an input hole which is provided to penetrate the front panel; a first chamber which is positioned in the cabinet and provides a space for accommodating clothes; a second base; a second chamber; a supply unit in the second chamber and supplying at least one of air and moisture into the first chamber; and a heat insulation unit formed by foaming plastic in a foam space formed between the cabinet, the first base, the first chamber, and the second base.

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; and
a rear panel defining a rear surface of the cabinet;

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, 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 rear panel;
a top frame extending from the front frame toward the rear panel and spaced apart from a bottom surface of the first chamber; and
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 rear panel;
a flow channel defining portion configured to communicate with the first chamber and the second chamber;
an air supply unit disposed inside the second chamber, and configured to supply air to the first chamber through the flow channel defining portion;
a door for opening and closing the laundry inlet;
a first hinge for connecting the door to a portion of the front panel disposed above the laundry inlet;
a second hinge for connecting the door to a portion of the front panel disposed below the laundry inlet;
a first hinge bracket fixed to the front panel and disposed inside the cabinet, wherein the first hinge bracket fixes the first hinge to the front panel; 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 foam space includes:
a space defined between the first chamber and the top panel;
a space defined between the first chamber and the first side panel;
a space defined between the first chamber and the second side panel;
a space defined between the first chamber and the rear panel;
a space defined between the first chamber and the top frame;
a space defined between the front panel and the front frame;
a space defined between the first side frame and the first side panel; and
a space defined between the second side frame and the second side panel.

3. The apparatus of claim 2 , wherein the foam plastic includes one of polyurethane, polystyrene, and polyolefin.

4. The apparatus of claim 2 , wherein the apparatus further comprises:
a first mounting portion recessed in the front panel toward an inside of the cabinet;
a first first-hinge mounting portion disposed on a left side of the first mounting portion, wherein the first first-hinge mounting portion protrudes from the front panel toward the inside of the cabinet, and the first first-hinge mounting portion has a first groove defined therein, wherein the first hinge is fixedly received in the first groove;
a second first-hinge mounting portion disposed on a right side of the first mounting portion, wherein the second first-hinge mounting portion protrudes from the front panel toward the inside of the cabinet, and the second first-hinge mounting portion has a second groove defined therein, wherein the first hinge is fixedly received in the second groove;
a second mounting portion recessed in an exposed surface of the front panel toward the inside of the cabinet;
a first second-hinge mounting portion disposed on a left side of the second mounting portion, wherein the first second-hinge mounting portion protrudes from the front panel toward the inside of the cabinet, and the first second-hinge mounting portion has a third groove defined therein, wherein the second hinge is fixedly received in the third groove; and
a second second-hinge mounting portion disposed on a right side of the second mounting portion, wherein the second second-hinge mounting portion protrudes from the front panel toward the inside of the cabinet, and the second second-hinge mounting portion has a fourth groove defined therein, wherein the second hinge is fixedly received in the fourth groove.

5. The apparatus of claim 4 , wherein the first hinge bracket includes:
a bracket body fixed to the first mounting portion and disposed in a space defined between the first chamber and the top panel;
a first receiving portion defined in the bracket body and constructed to accommodate therein the first first-hinge mounting portion; and
a second receiving portion defined in the bracket body and constructed to accommodate therein the second first-hinge mounting portion.

6. The apparatus of claim 5 , wherein the apparatus further comprises:
a first position-fixing portion protruding from the first mounting portion toward the bracket body; and
a second position-fixing portion defined in the bracket body and constructed to accommodate therein the first position-fixing portion.

7. The apparatus of claim 5 , wherein the first receiving portion and the second receiving portion are symmetrical shapes with respect to a central line virtually passing through the center of the bracket body along a height of the cabinet.

8. The apparatus of claim 4 , wherein the bottom panel includes:
a first bottom panel having a front surface fixed to the front panel, a rear surface fixed to the front frame, and both side surfaces fixed to a bottom surface of the first side panel and a bottom surface of the second side panel, respectively; and
a second bottom panel having a front surface connected to a rear surface of the first bottom panel, and both side surfaces fixed to a bottom surface of the first side panel and a bottom surface of the second side panel, respectively, wherein the second bottom panel is disposed below the second base.

9. The apparatus of claim 8 , wherein the apparatus further comprises a panel connector for connecting a rear surface of the first bottom panel and a front surface of the second bottom panel to each other.

10. The apparatus of claim 8 , wherein the apparatus further comprises:
a first second-hinge bracket for fixing the first second-hinge mounting portion and the first bottom panel;
a second second-hinge bracket for fixing the second second-hinge mounting portion and the first bottom panel;
a first leg coupled to at least one of the first second-hinge bracket or the first bottom panel; and
a second leg coupled to at least one of the second second-hinge bracket or the first bottom panel.

11. The apparatus of claim 10 , wherein the first second-hinge bracket includes:
