First claim

Opening claim text (preview).

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 arranged vertically with respect to the first 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 and the second cabinet, the third cabinet having an inner space for receiving laundry; a plate assembly for coupling the second cabinet and the third cabinet; a heating device disposed above the first cabinet and the second cabinet, the heating device for heating air supplied into the inner space of the third cabinet; and a supply air duct connecting the heating device and an upper portion of the refresher, wherein the supply air duct includes: a first supply air duct extending downwardly from the heating device and connected to the first drum; and a second supply air duct extending to a lateral side from the heating device and connected to the refresher, wherein the first cabinet includes a first inner wall facing the refresher, wherein the second cabinet includes a second inner wall facing the third cabinet, wherein the third cabinet includes a third inner wall facing the second cabinet, wherein the plate assembly is disposed between the second inner wall and the third inner wall, wherein the plate assembly includes: a first plate disposed between the second inner wall and the third inner wall; a second plate connected to the first plate and extending horizontally at a position under the second cabinet and the third cabinet; and a grip recessed upwardly from a lower surface of the second plate. 2. The laundry treating apparatus of claim 1 , wherein the refresher further includes: a supply air hole connected to the supply air duct at the upper portion of the refresher; an exhaust air duct connecting the refresher and the heating device; and an exhaust air hole connected to the exhaust air duct. 3. The laundry treating apparatus of claim 2 , wherein the third cabinet includes: a top surface; and an inclined surface extending obliquely downwardly from the top surface, and wherein the supply air hole is open obliquely downwardly toward the inner space of the third cabinet at the inclined surface. 4. The laundry treating apparatus of claim 2 , wherein the refresher further includes a hanger for hanging clothing in the inner space of the third cabinet, and wherein the supply air hole is positioned above the hanger. 5. The laundry treating apparatus of claim 4 , wherein the exhaust air hole is formed at the upper portion of the refresher, and wherein the exhaust air hole is positioned below the supply air hole. 6. The laundry treating apparatus of claim 5 , wherein the supply air hole and the exhaust air hole are open toward the inner space of the third cabinet at positions horizontally spaced apart from each other. 7. The laundry treating apparatus of claim 1 , further comprising a dehumidification duct disposed above the first drum and the second drum, the dehumidification duct for discharging the air heated by the heating device to an outside of the laundry treating apparatus. 8. The laundry treating apparatus of claim 7 , further comprising a partition wall disposed above the first drum and the second drum and disposed below the heating device, wherein the heating device comprises a heat exchange unit for heating the air supplied into the inner space of the third cabinet; and a heat exchange channel in which the heat exchange unit is disposed, the heat exchange channel being spaced from an upper side of the partition wall, and wherein the dehumidification duct is disposed in a space formed between the partition wall and the heat exchange channel. 9. The laundry treating apparatus of claim 8 , further comprising an outside air inlet disposed above the first drum and the second drum and adjacent to the dehumidification duct, wherein the outside air inlet is connected to the heat exchange channel. 10. The laundry treating apparatus of claim 1 , further comprising: a first exhaust air duct connecting the first drum and the heating device; and a second exhaust air duct connecting the refresher and the heating device, wherein the first exhaust air duct is joined to the second exhaust air duct. 11. The laundry treating apparatus of claim 1 , further comprising: a steam generator disposed in the heating device; and a steam supply pipe connecting the steam generator and the upper portion of the refresher. 12. The laundry treating apparatus of claim 1 , wherein the dryer includes a first laundry loading opening and a first door for opening and closing the first laundry loading opening, the first door being rotatable downward, wherein the washer includes a second laundry loading opening and a second door for opening and closing the laundry loading opening, and wherein the washer is disposed above the dryer.
