Problems solved by technology

[0004] However, in the later stage of drying, the humidity of the clothes to be dried decreases, the heat required for the clothes to be dried decreases, and the temperature of the hot and humid air discharged from the drum will increase accordingly. The high-load working state causes the compressor to start and stop frequently, which affects the drying efficiency

Abstract

The invention belongs to the technical field of clothes dryers, and particularly relates to a heat pump clothes dryer. The clothes dryer aims to solve the problem that a compressor frequently starts and stops in the prior art, and drying efficiency is affected. The heat pump clothes dryer comprises a roller, a heat pump system, a fan and a ventilation assembly, wherein a dry hot wind inlet and a humid hot wind outlet are formed in the roller, the heat pump system comprises an air duct, a condenser and an evaporator, an inlet hole and an outlet hole capable of opening and closing are formed inthe ventilation assembly, the inlet hole is used to lead cold air outside the air duct into a first part of the humid hot wind outlet connecting the evaporator and the roller, and the outlet hole is used to exhaust part of hot and humid air in the first part. Through the above arrangement, the temperature of the hot and humid air exchanging heat with refrigerant in an evaporator pipeline is reduced, so that the exhaust temperature of the compressor is reduced, and the reduction of drying efficiency caused by frequent start and stop of the compressor due to high load is avoided.

Description

technical field [0001] The invention belongs to the technical field of clothes dryers, and in particular relates to a heat pump clothes dryer. Background technique [0002] A heat pump clothes dryer is a common household appliance used to dry clothes. [0003] The heat pump clothes dryer includes a drum, a fan, an air duct and a heat pump system; the drum communicates with the air duct, the heat pump system includes a compressor, a condenser and an evaporator, and at least the fan, the condenser and the evaporator are arranged in the air duct. When the heat pump dryer is working, the refrigerant undergoes a gas-liquid two-phase change in the heat pump system to absorb or release heat. Among them, the refrigerant condenses and releases heat at the condenser; the fan drives the air in the air duct to pass through the condenser, and the air absorbs heat. The heat rises and turns into hot and dry air, which is sent into the drum and takes away the moisture of the clothes and tu...
