Condensing unit and clothes dryer with condensing unit

Abstract

The invention discloses a condensing unit, which comprises a semiconductor refrigeration fin, wherein two sides of the semiconductor refrigeration fin are respectively connected with hot end cooling fins and cold end heat absorbing fins through two heat conduction blocks, and a heat insulation material is filled between the hot end cooling fins and the cold end heat absorbing fins so as to insulate the heat conduction between the hot end cooling fins and the cold end heat absorbing fins. The clothes dryer comprises a clothes drying cavity and a circulating air duct, wherein two ends of the circulating air duct are communicated with the clothes drying cavity, and the condensing unit is arranged into the circulating air duct. The air in the circulating air duct is condensed and dehumidified through the cold end heat absorbing fins of the condensing unit when the air is circulated, and then, is returned into the clothes drying cavity after being heated by the hot end cooling fins. The condensing device and the clothes drying machine with the condensing device can condense water vapor and heat the air, and makes the best of the air circulation, so that the clothes drying machine has higher clothes drying efficiency and is free from vibration and noise.

Description

technical field [0001] The invention relates to a clothes dryer, in particular to a clothes dryer with a condensing device. Background technique [0002] A clothes dryer is a cleaning appliance that uses electric heat to automatically dry clothes. It is especially needed in areas where the air humidity is high and clothes are not easy to dry. Clothes dryers are divided into drum type and cabinet type according to the structure, with drum type being the majority. A tumble dryer is generally composed of a cabinet, a drum system, a hot air system, a transmission and a control system; it can be divided into exhaust type and dehumidification type according to the moisture removal method. The air is directly discharged to the outside of the machine, and the dehumidification type is to pass the high-temperature and high-humidity air through the heat exchanger to generate condensed water and then discharge it to the outside of the machine. Existing clothes dryers have water-coolin...

AI Technical Summary

Problems solved by technology

However, in this clothes dryer, the semiconductor cooling plate is arranged outside the air duct, and the condenser and evaporator in the air duct are connected to the external semiconductor cooling plate through heat exchange tubes, which makes the condensation heating structure complicated; at the same time, a certain amount of cooling or heat will be The loss is outside the air duct, causing the problem of low drying efficiency
