In the scheme, the heat conducting part 12 is fastened on the drying air duct 2 by arranging the pin shaft 124, the assembling structure is stable, the pin shaft 124 and the heat conducting part 12 can be integrally formed, and the materials can be the same or different; in addition, the pin 124 may be detachably connected to the heat conducting portion, so as to facilitate the detachment and installation.

In a preferred embodiment, the clothes treatment device comprises a plurality of heating elements 1, each heating element 1 is provided with a pin shaft 124 in a protruding manner, a mounting hole 225 is formed in the drying air channel corresponding to each heating element 1, the heating elements are sequentially arranged along the length direction of the drying air channel and are arranged in parallel to each other, extend along the width direction of the drying air channel and are inserted into the corresponding mounting holes 225 through the pin shafts 124. In this scheme, through set gradually a plurality of heat-generating bodies on the stoving wind path, heating efficiency has been improved. In addition, in order to prevent the accumulation of the batting between the adjacent heating elements 1, the space between the adjacent heating elements 1 can be reasonably set, or the height position of each heating element 1 is adjusted, so that each heating element 1 is arranged in a staggered mode, the plurality of heating elements 1 are prevented from shielding each other to form an air path dead zone, and the batting is accumulated in the air path dead zone.

Referring to fig. 11, a sealing ring 5 is disposed between the pin 124 and the inner wall of the mounting hole 225, and a heat insulating portion 3 is coated on a shaft section of the pin 124 between the sealing ring 5 and the heat conducting portion 12. In this scheme, set up sealing washer 5 on round pin axle 124 for the inside stoving wind channel in stoving wind channel is kept apart with the external world, has avoided the heat to run off, and the cladding sets up thermal-insulated portion between sealing washer 5 and heat-conducting part 12 simultaneously, and the heat that reduces heat-conducting part 12 passes to stoving wind channel 2 on, further prevents the heat loss, is showing improvement product energy conservation performance.

In summary, according to the embodiments, the heating element of the clothes processing apparatus of the present application is designed to be of the streamline structure, so that the heating element has little obstruction to the drying air during the drying process, and the lint carried in the air cannot be adhered and accumulated by the heating element, so that the inside of the drying air duct is clean, the smoothness of the drying air duct is ensured, and the clothes processing apparatus maintains good drying performance.

The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
