Abstract

A clothes treatment apparatus, including a drum rotatably provided within a cabinet to accommodate washing and drying objects; and a heat pump including an evaporator, a compressor, a condenser, and an expansion valve, through which refrigerant is circulated, to provide heat to air discharged from the drum and circulated to the drum, wherein the heat pump further includes an internal heat exchanger configured to exchange heat between refrigerant discharged from the condenser and refrigerant passing through the evaporator.

First claim

What is claimed is:

1. A clothes treatment apparatus, comprising:
a tub provided within a cabinet to store wash water;
a drum rotatably provided within the tub to accommodate washing and drying objects; and
a heat pump including an evaporator, a gas-liquid separator, a compressor, a condenser, and an expansion valve, through which refrigerant is circulated to provide heat to air circulated through the drum,
wherein the heat pump further includes:
a heat exchange duct configured to accommodate the evaporator and the condenser and connected to the tub to form a flow path to circulate the air;
a compressor base integrally connected to a rear portion of the heat exchange duct to support the compressor;
a gas-liquid separator mount integrally formed with a rear portion of the heat exchange duct and one lateral portion of the compressor base to support the gas-liquid separator; and
an internal heat exchanger provided within the evaporator and including an internal heat exchange pipe extending from the condenser to an inside of the evaporator to exchange heat between the internal heat exchange pipe and a refrigerant pipe of the evaporator within the evaporator.

2. The clothes treatment apparatus of claim 1 , wherein the heat exchange duct partially covers an upper front portion of the tub, the compressor base covers a first part of an upper rear portion of the tub, the gas-liquid separator mount covers a second part of the upper rear portion of the tub, a front portion of the heat exchange duct is fastened to a front surface of the cabinet, and a rear portion of the compressor base is fastened to a rear surface of the cabinet.

3. The clothes treatment apparatus of claim 2 , wherein an air inlet of the heat exchange duct is communicably connected to an upper left rear portion of the tub, and an air outlet of the heat exchange duct is communicably connected to an upper right front portion of the tub.

4. The clothes treatment apparatus of claim 3 , wherein an outlet of the heat exchange duct is communicably connected to a gasket provided in front of the tub.

5. The clothes treatment apparatus of claim 3 , wherein the internal heat exchanger pipe includes an internal heat exchange pipe arranged in one row or two rows at a downstream side of the evaporator with respect to the movement direction of the air, a refrigerant inlet of the evaporator is provided at an upstream side of the evaporator, a refrigerant outlet of the evaporator is provided at a downstream side of the evaporator, and a first refrigerant pipe extending from the expansion valve to the refrigerant inlet of the evaporator and a second refrigerant pipe extending from the refrigerant outlet of the evaporator to the gas-liquid separator intersect with each other.

6. The clothes treatment apparatus of claim 3 , wherein the internal heat exchanger pipe includes an internal heat exchange pipe arranged in one row or two rows at a downstream side of the evaporator with respect to the movement direction of the air, a refrigerant outlet of the evaporator is provided at an upstream side of the evaporator, a refrigerant inlet of the evaporator is provided at a downstream side of the evaporator, and a first refrigerant pipe extended from the expansion valve to the refrigerant inlet of the evaporator and a second refrigerant pipe extended from the refrigerant outlet of the evaporator to the gas-liquid separator are parallel to each other.

7. The clothes treatment apparatus of claim 1 , wherein a part of the heat exchange duct in which the evaporator and the condenser are accommodated, the compressor base on which the compressor is mounted, and the gas-liquid separator mount are sequentially arranged in a lateral direction from a central line in an axial direction of the tub to cover a first upper side of the tub.

8. A clothes treatment apparatus, comprising:
a tub provided within a cabinet to store wash water;
a drum rotatably provided within the tub to accommodate washing and drying objects; and
a heat pump including an evaporator, a gas-liquid separator, a compressor, a condenser, and an expansion valve, through which refrigerant is circulated, to provide heat to air discharged from the drum and circulated to the drum,
wherein the heat pump further includes:
a compressor base configured to support the compressor; and
an internal heat exchanger provided within the evaporator, the internal heat exchanger including an internal heat exchange pipe extending from the condenser to an inside of the evaporator to exchange heat between the internal heat exchange pipe and a refrigerant pipe of the evaporator within the evaporator.

9. The clothes treatment apparatus of claim 8 , wherein the compressor is a horizontal compressor in which a rotating shaft is provided in an axial direction of the tub.

10. The clothes treatment apparatus of claim 9 , wherein the compressor includes:
a bracket having a central portion surround a part of an upper outer circumferential surface of a compressor body, and an edge portion arranged at an upper portion of the compressor base and fastened to the compressor base to support the compressor body while hanging the compressor body at an upper portion of the compressor base; and
an anti-vibration mount provided between the edge portion of the bracket and the upper portion of the compressor base to elastically support the bracket.

11. The clothes treatment apparatus of claim 9 , wherein a refrigerant outlet of the compressor faces a refrigerant inlet pipe of the condenser.
