Abstract

A laundry treating apparatus including a dryer including a first cabinet, and a first drum rotatably disposed in the first cabinet, a washing machine including a second cabinet disposed over the second cabinet, a tub disposed in the second cabinet, and a second drum rotatably disposed in the tub, a refresher including a third cabinet disposed at a lateral side of the first cabinet, the third cabinet having an inner space for receiving laundry, a first supply air duct for supplying air into the first drum, a second supply air duct for supplying air into the inner space of the second cabinet, a third supply air duct, and a heating device for heating air flowing into the first supply air duct and the second supply air duct, the heating device being disposed under the first drum.

First claim

What is claimed is:

1 . A laundry treating apparatus comprising:
a dryer including:
a first cabinet; and
a first drum rotatably disposed in the first cabinet;
a washing machine including:
a second cabinet disposed over the second cabinet;
a tub disposed in the second cabinet; and
a second drum rotatably disposed in the tub;
a refresher including a third cabinet disposed at a lateral side of the first cabinet, the third cabinet having an inner space for receiving laundry; a first supply air duct for supplying air into the first drum; a second supply air duct for supplying air into the inner space of the second cabinet; a third supply air duct for supplying air into the second drum, the third supply air duct branching off from the second supply air duct; and a heating device for heating air flowing into the first supply air duct and the second supply air duct, the heating device being disposed under the first drum, wherein the dryer, the refresher and the washing machine are disposed adjacently, wherein the washing machine and the dryer are vertically disposed adjacently, wherein the refresher is disposed on one side of the washing machine and the dryer adjacently, wherein the heating device is disposed under the first drum and the second cabinet, and wherein the second supply air duct extends laterally from the heating device and is connected to the refresher.

2 . The laundry treating apparatus of claim 1 , wherein the third supply air duct extends upwardly from the second supply air duct.

3 . The laundry treating apparatus of claim 1 , further comprising a control valve disposed at a position where the third supply air duct branches off from the second supply air duct.

4 . The laundry treating apparatus of claim 1 , wherein a supply air hole of the refresher is disposed at a lower portion of the refresher.

5 . The laundry treating apparatus of claim 1 , wherein the heating device includes:
a heat exchange unit for heating air; and a heat exchange channel in which the heat exchange unit is disposed, and wherein the first supply air duct and the second supply air duct are connected to the heat exchange channel.

6 . The laundry treating apparatus of claim 1 , further comprising:
a steam generator disposed in the heating device; a first steam supply pipe connecting the steam generator and the first drum; a second steam supply pipe connecting the steam generator and the refresher; and a third steam supply pipe connecting the steam generator and the tub.

7 . The laundry treating apparatus of claim 1 , further comprising:
a first exhaust air duct supplying air in the first drum to the heating device; a second exhaust air duct supplying air in the third cabinet to the heating device; and a third exhaust air duct supplying air in the second drum to the heating device.

8 . The laundry treating apparatus of claim 7 , wherein the second exhaust air duct extends in a left-right direction, to be connected to the heating device.

9 . The laundry treating apparatus of claim 8 , wherein the second exhaust air duct is connected to the third exhaust air duct.
