Abstract

A clothes treating apparatus may include a heat pump that is detachable and controlled according to a plurality of operation modes. The plurality of operation modes may include a drying mode configured to control operation of the heat pump when the heat pump is mounted on the cabinet and a dehumidification mode configured to control operation of the heat pump when the heat pump is separated from the cabinet. The heat pump may be used in a separable manner when separated therefrom as well as when mounted thereon.

First claim

What is claimed is:

1. A clothes treating apparatus comprising:
a cabinet that includes a clothing storage chamber, a heat pump storage chamber, and a door to open and close the clothing storage chamber and the heat pump storage chamber;
a control panel mounted on the door to receive a control command; and
a heat pump configured to transfer air to the clothing storage chamber, and the heat pump being separably mounted at the heat pump storage chamber of the cabinet, wherein the heat pump includes:
an evaporator, a compressor, a condenser and an expansion apparatus configured to form a refrigerant compression cycle;
a heat pump controller configured to control operation of the heat pump according to a plurality of operation modes;
a heat pump power supply unit;
a case provided with the evaporator, the compressor, the condenser, the expansion apparatus, the heat pump controller and the heat pump power supply unit; and
a heat pump control panel, provided at a surface of the case, to receive a control command, and the heat pump control panel to provide the control command to the heat pump controller,

wherein the plurality of operation modes comprise:
a drying mode configured to control operation of the heat pump when the heat pump is provided in the cabinet; and
a dehumidification mode configured to control operation of the heat pump when the heat pump is separated from the cabinet,

wherein when the heat pump is mounted at the cabinet, the heat pump controller receives a control command from the control panel mounted on the door, and
when the heat pump is separated from the cabinet, the heat pump controller receives a control command from the heat pump control panel,
wherein the heat pump includes an air intake port and an air discharge port to communicate with the clothing storage chamber, exposing an upper surface of the case of the heat pump,
wherein the clothing storage chamber includes an air supply port to receive air from the air discharge port of the heat pump, and air discharge port to transfer air in the clothing storage chamber to the air intake port of the heat pump,
wherein the air supply port and the air discharge port of the clothing storage chamber are formed to pass through a lower surface of the clothing storage chamber,
wherein a taper portion is provided between the air discharge port of the clothing storage chamber and the air intake port of the heat pump, the taper portion extending in an inclined manner toward an edge of the air intake port from a frame edge of the air discharge port of the clothing storage chamber, and
wherein an air discharge port stepped portion is formed on the air discharge port of the heat pump, the air discharge port stepped portion horizontally extending from the air discharge port of the heat pump to outside of the heat pump and bending upward toward the air supply port the clothing storage chamber.

2. The clothes treating apparatus of claim 1 , wherein a temperature of air supplied by the heat pump in the drying mode is higher than a temperature of air supplied by the heat pump in the dehumidification mode.

3. The clothes treating apparatus of claim 1 , wherein a driving speed of the compressor in the drying mode is faster than a driving speed of the compressor in the dehumidification mode.

4. The clothes treating apparatus of claim 1 , wherein an extent of compressing refrigerant by the compressor in the drying mode is higher than an extent of compressing refrigerant by the compressor in the dehumidification mode.

5. The clothes treating apparatus of claim 1 , wherein the heat pump further includes:
a heater on an air passage, the heater provided downstream of the condenser, and
the heat pump controller controls operation of the heater in the drying mode, and the heat pump controller maintains the heater to be in an off state in the dehumidification mode.

6. The clothes treating apparatus of claim 1 , wherein the heat pump power supply unit includes a connecting portion to couple to an external power source.

7. The clothes treating apparatus of claim 6 , further comprising:
a power supply unit at the cabinet, and the power supply unit to connect to an external power source,
wherein the connecting portion is to couple to the power supply unit.

8. The clothes treating apparatus of claim 1 , wherein the heat pump includes a plurality of wheels provided on a base corresponding to a lower surface of the case in such a manner that a distance between two wheels provided at a front side of the base is different from a distance between two wheels provided at a rear side of the base.

9. The clothes treating apparatus of claim 8 , wherein guide rails are provided on a lower surface of the heat pump storage chamber to guide the two wheels of the rear side of the base.
