Abstract

Provided is a garment processing apparatus for compactly optimizing the arrangement space of a heat pump system. A heat pump module is modularized by integrally mounting a compressor, a condenser, and an evaporator in an integrated housing and is disposed at an upper portion of a tub.

First claim

What is claimed is:

1. A garment processing apparatus comprising:
a cabinet;
a tub provided inside the cabinet;
a drum rotatably provided in the tub and providing a reception space for washing and drying laundry; and
a heat pump module configured to circulate refrigerant to a compressor, a condenser, an expansion valve, and an evaporator, and re-circulate air discharged from the drum to the drum through the evaporator and the condenser,
wherein the heat pump module includes an integrated housing in which the compressor, the condenser, and the evaporator are integrally mounted,
wherein the heat pump module is provided above an upper outer circumferential surface of the tub and supported by a plurality of fasteners to a front surface and a rear surface of the cabinet,
wherein the integrated housing includes:
a heat exchange duct part configured to receive the evaporator and the condenser; and
a compressor base part configured to support the compressor,

wherein the heat exchange duct part and the compressor base part are interconnected integrally and support each other,
wherein the garment processing apparatus further comprises:
a bracket coupled to the compressor; and
a plurality of anti-vibration mounts positioned between the bracket and the compressor base part,

wherein the bracket and the plurality of anti-vibration mounts are positioned on an upper region of the compressor base part such that the compressor hangs from the upper region of the compressor base part, and
wherein the bracket is provided above a part of an outer surface of the compressor that contacts the bracket, and the bracket includes:
a middle portion fixed to the part of the outer surface of the compressor; and
edge parts extended from the middle portion toward each of the plurality of anti-vibration mounts, the edge parts being coupled to the anti-vibration mounts.

2. The garment processing apparatus of claim 1 , wherein
a plurality of fastening protrusions are provided at a front surface and a rear surface of the integrated housing, each of the plurality of fastening protrusions having a cylindrical shape that protrudes outward, and
the plurality of fasteners are inserted into and screw-fastened to the plurality of fastening protrusions.

3. The garment processing apparatus of claim 2 , wherein the heat exchange duct part is connected to the tub to form a flow passage to circulate air discharged from the tub; and
wherein the plurality of fasteners fasten a front surface of the heat exchange duct part to a front surface of the cabinet and fasten a rear surface of the compressor base part to a rear surface of the cabinet.

4. The garment processing apparatus of claim 3 , wherein at least two of the plurality of fastening protrusions are formed at different positions at each of a front surface of the heat exchange duct part and a rear surface of the compressor base part.

5. The garment processing apparatus of claim 2 , wherein the fastening protrusions are first fastening protrusions, and wherein the garment processing apparatus further comprises:
a second fastening protrusion provided to surround an outer circumference surface of one of the first fastening protrusions, the second fastening protrusion having a prescribed shape that surrounds an outer circumference of the first fastening protrusion; and
a plurality of reinforcing ribs that extend in a radial direction from the outer circumference surface of the first fastening protrusion to the second fastening protrusion.

6. The garment processing apparatus of claim 2 , further comprising a reinforcing rib that protrudes radially from an outer circumferential surface of one of the fastening protrusions, the reinforcing rib being provided between the fastening protrusion and a front surface or a rear surface of the integrated housing.

7. The garment processing apparatus of claim 2 , wherein the fastening protrusions are first fastening protrusions, and wherein the garment processing apparatus further comprises:
a second fastening protrusion that protrudes from a front surface or a rear surface of the integrated housing to surround an outer circumferential surface of one of the first fastening protrusions, wherein at least one inner side surface of the second fastening protrusion contacts the first fastening protrusion.

8. The garment processing apparatus of claim 2 , further comprising protrusions provided a prescribed distance from the plurality of fastening protrusion at a front surface and a rear surface of the integrated housing, wherein a guide hole to accommodate one of the protrusions is formed at each of the front surface and the rear surface of the cabinet.

9. The garment processing apparatus of claim 1 , wherein the part of the outer surface of the compressor has a convex upward curved shape, and a region of a lower surface of the middle portion of the bracket that contacts the part of the outer surface of the compressor has a curved shape that opens downward and corresponds to the shape of the part of the outer surface of the compressor.

10. The garment processing apparatus of claim 9 , wherein the compressor base part has a U-shaped section that opens upward to receive a portion of a lower circumferential surface of the compressor.

11. The garment processing apparatus of claim 10 , wherein
the compressor base part further includes supports that extend vertically to receive side surfaces of the compressor, and
lower ends of the plurality of anti-vibration mounts are positioned on an upper surface of the supports.

12. The garment processing apparatus of claim 11 , further comprising bolts, each of the bolts being configured to be inserted through a hole in the upper surface of the supports, an interior of one of the anti-vibration mounts, and an opening in one of the edge parts to couple the bracket and the one of the anti-vibration mounts.

13. The garment processing apparatus of claim 1 , wherein the middle portion of bracket is welded to one or more places on the outer surface of the compressor.

14. The garment processing apparatus of claim 13 , wherein the middle portion of bracket is welded to the outer surface of the compressor at three places, the three places including two places at opposite sides of a discharge port of the compressor and a third place that is rear of the discharge port.

15. The garment processing apparatus of claim 1 , wherein the compressor is inclined with respect to a horizontal plane, and a region of a lower surface of the middle portion that is fixed to the part of the outer surface of the compressor is inclined with respect to the horizontal plane.

16. The garment processing apparatus of claim 1 , wherein
the integrated housing further includes a gas-liquid separator mounting part provided between a rear of the heat exchange duct part and a side surface of the compressor base part, and
the heat pump module further includes a gas-liquid separator installed on a refrigerant pipe connecting the evaporator and the compressor and positioned at the gas-liquid separator mounting part.

17. The garment processing apparatus of claim 16 , wherein the integrated housing further includes a pressure switch mounting part provided rear of the gas-liquid separator part, and the heat pump module further includes a pressure switch positioned at pressure switch mounting part.

18. The garment processing apparatus of claim 1 , wherein the integrated housing further includes a fan duct part that extends vertically at a side of the heat exchange duct part, and the heat pump module further i
