Problems solved by technology

[0012] However, in the plurality of operation modes, during the cycle of the refrigerant cycle, the refrigerant circulates the same flow rate in the first operation mode and the eco mode, thereby causing a problem that the desired flow rate of the refrigerant cannot be controlled.
In order to realize multiple operating modes, the heat pump needs to have a complex structure and complex control

Abstract

The present disclosure relates to a clothes dryer provided with an expansion device capable of changing according to a change in operation mode, and more particularly, to a condensing heat pump clothes dryer and an operation method thereof, wherein, in a multi-operation mode In the clothes dryer, the expansion device can be changed according to the opening / closing of the solenoid valve using the user's operating mode input during the selection of the first operating mode for turning on the heater or the second operating mode for turning off the heater. , so as to control the required refrigerant flow.

Description

technical field [0001] The present disclosure relates to a heat pump type clothes dryer and an operating method thereof, which enable refrigerant to flow in a heat pump of the clothes dryer having a plurality of operation modes. Background technique [0002] In general, a laundry treatment apparatus with a drying function such as a washing machine or a clothes dryer is a device for putting laundry in a drum and supplying hot air to the drum in a state where washing is completed to terminate the spinning process to dry the clothes by evaporating the moisture in the clothes. [0003] As an example of the above-mentioned clothes dryer, the aforementioned clothes dryer may include: a drum rotatably provided in the cabinet to put laundry therein; a driving motor configured to drive the drum; a blower fan configured to blow air into the drum; and a heating device configured to heat the air introduced into the drum. In addition, the heating means may use high-temperature resistan...
