Description

Clothes processing device {LAUNDRY TREATING APPARATUS}

The present disclosure relates to a laundry treatment device, and more particularly, to a refresher in which a heating device is disposed.

The clothes handling device is a device that manages a sanitary state of clothes accommodated in a cabinet through actions such as washing, drying, and refreshing.

The laundry treatment apparatus includes a heating apparatus equipped with a heat pump apparatus for drying or refreshing the laundry accommodated inside the cabinet.

The heating device includes a compressor through which refrigerant is circulated, a condenser, an evaporator, and an expansion device. In addition, the heating device includes a drain tank for storing condensed water generated in the evaporator, and a separate drain facility for discharging the condensed water stored in the drain tank.

However, in the conventional clothes handling apparatus, since the heating device is disposed inside the cabinet of the refresher, the internal volume of the refresher is reduced due to the drain tank and drainage equipment occupying a large volume.

In addition, the conventional laundry treatment apparatus has a problem in that energy consumption is excessive because heating devices are disposed in each of the dryer and the refresher that require the supply of hot air.

Korean Registered Patent No. 10-2254903 discloses a heating device disposed inside the refresher, but there is a problem in that the space for accommodating clothes inside the refresher is narrowed due to the volume occupied by the drainage tank and the drainage system. In addition, when the dryer is disposed together with the refresher, there is a problem in that energy consumption is excessive due to the heating devices of the refresher and the dryer being driven simultaneously.
