Heat pump type clothes dryer capable of washing heat exchanger with water

Abstract

The invention discloses a heat pump type clothes dryer capable of washing a heat exchanger with water, and relates to the technical field of clothes dryers, wherein the heat pump type clothes dryer can remove thread scraps and other debris on the heat exchanger and ensure the heat exchange efficiency. The heat pump type clothes dryer capable of washing the heat exchanger with water comprises a barrel body and an air channel communicating with the barrel body and used for drying to-be-dried articles in the barrel body, wherein a fan and the heat exchanger are arranged in the air duct; the heatexchanger comprises an evaporator and a condenser; the fan is used for blowing moisture from the barrel body to the evaporator; the evaporator is used for reducing the temperature of hot humid air toform condensed water; the air after passing through the evaporator is heated by the condenser and then enters the barrel body again; the heat pump type clothes dryer further comprises a nozzle devicefor rinsing the heat exchanger; and the nozzle device communicates with a water supply device through a water pipe. The heat pump type clothes dryer provided by the invention is used to dry clothes.

Description

technical field [0001] The invention relates to the technical field of clothes dryers, in particular to a heat pump dryer with a water-washable heat exchanger. Background technique [0002] A clothes dryer is a cleaning household appliance that uses electric heating or a heat exchanger (heat pump type) to generate a higher temperature air flow so that the moisture in the washed clothes can be evaporated and dried immediately. It is especially necessary for the winter in the north and the "returning to the south" in the south where the clothes are difficult to dry. In addition, clothes dryers are widely used in industrial production to dry fabrics and improve production efficiency. [0003] Heat pump dryers in the prior art generally include an inner tub for holding clothes, an air duct is formed under the inner tub, and a heat exchanger (including an evaporator and a condenser) is arranged in the air duct, and the two ends of the inner tub are connected to the air duct.

Problems solved by technology

[0004] However, the heat pump dryers in the prior art will take away the lint between the clothes during the drying process of the high-temperature air, and the lint in the air will be attached to the evaporator or condenser after passing through the evaporator or condenser. As the drying time prolongs, the lint attached to the fin surface of the evaporator or condenser will continue to increase, which will increase the air resistance in the air duct, reduce the heat exchange efficiency, and reduce the condensation efficiency
