Problems solved by technology

[0014] However, the existing method of installing a sub-condenser and forming an independent flow path will increase additional costs, and because the heat dissipation of the condenser is discharged to the outside, there is a limit to directly improving the dehumidification performance in the evaporator.

Abstract

A clothes treating apparatus that includes a heat pump cycle and a dehumidifying device is provided herein. The clothes treating apparatus may include a case and a drum installed within the case and configured to accommodate an item for drying. A circulation duct may be provided to form an air circulation flow channel that allows air to circulate through the drum. The heat pump cycle may include an evaporator and a condenser disposed to be spaced apart from one another within the circulation duct, the heat pump cycle being configured to absorb heat of air released from the drum through the evaporator and transmit the absorbed heat to air introduced to the drum through the condenser, by using a working fluid that circulates by way of the evaporator and the condenser. Moreover, the dehumidification device may be provided to dehumidify air passing through the evaporator in the circulation duct.

Description

technical field [0001] The present invention relates to a laundry treating device having a heat pump cycle, and more particularly, to a stable laundry treating device capable of improving dehumidification performance and facilitating circulation. Background technique [0002] Generally, a clothes processing device with a drying function such as a washing machine or a dryer puts the laundry in the state of completing the washing and dehydration process into the drum, and supplies hot air to the inside of the drum to evaporate the moisture of the laundry for drying. Device for washing. [0003] Clothes dryers can be classified into exhaust-type clothes dryers and condensation-type clothes dryers according to the treatment method of the humid air passing through the drum after drying the laundry. [0004] The exhaust type clothes dryer discharges the humid air that comes out of the drum to the outside of the dryer, and the condensation type clothes dryer does not discharge the...
