Abstract

A clothes treating apparatus having a heat pump cycle for performing a washing cycle and a drying cycle is provided. The clothes treating apparatus may include a drum configured to accommodate a item to be treated; a heat pump cycle having a first evaporator, a compressor, a condenser, and an expansion valve to heat air introduced into the drum; a circulation duct configured to form a circulation passage of air that has passed through the drum; a circulation fan configured to circulate the air; and a controller configured to drive the heat pump cycle and the circulation fan during the washing cycle to preheat at least one of the drum or the circulation duct.

Description

technical field [0001] The present invention relates to a laundry treatment device having a heat pump cycle capable of shortening drying time by preheating before starting a drying course. 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 where the washing and dehydration process is completed into the drum, and supplies hot air to the inside of the drum to evaporate the moisture of the laundry to dry the laundry. object device. [0003] Clothes dryers can be classified into exhaust-type clothes dryers and condensation-type clothes dryers according to how humid air passing through a drum is treated after drying 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 humid air that comes out of the drum to the outside of the dryer, bu...
