Abstract

The invention relates to the technical field of clothes treatment equipment, in particular to a drying air duct assembly and clothes treatment equipment comprising the drying air duct assembly. In order to solve the problems that a heating device in an existing drying air duct is low in safety, slow in temperature rise and low in heat conductivity, the drying air duct assembly comprises an air duct outer shell, a draught fan, an insulating shell and a superconductive heating piece, and a first air inlet and a first air outlet are formed in the air duct outer shell; the fan and the superconductive heating piece are arranged in the air duct outer shell and located between the first air inlet and the first air outlet, the insulating shell covers the superconductive heating piece, and a second air inlet and a second air outlet are formed in the two ends of the insulating shell in the air direction respectively. The superconductive heating element has the advantages of small thermal resistance, high heat exchange efficiency and power saving, has the characteristics of rapid heat dissipation and instant cooling after power failure, can automatically keep constant temperature, improves the safety of the drying air duct, and can effectively prevent electric shock and improves the safety performance as the insulating shell separates the superconductive heating element from the air duct outer shell.

Description

technical field [0001] The present invention relates to the technical field of clothes treatment equipment, and in particular provides a drying air duct assembly and a clothes treatment device including the drying air duct assembly. Background technique [0002] With the improvement of living standards, more and more families use clothes dryers or integrated washing and drying machines to dry clothes. In the past, clothes dryers provided the air duct with the ability to dry clothes by setting an electric heating tube in the drying air duct. Heat, such as cast copper, cast aluminum or cast iron electric heating ring, etc., but the surface temperature of the electric heating tube is usually above 300 ℃, the electric heating tube cools down slowly, and the temperature controllability is poor, which often causes the surface of the electric heating tube to burn red. It is easy to cause safety hazards such as fire caused by the heating of the air duct shell. Those skilled in the ...
