Description

Sealing structure of clothes dryer and clothes dryer

Technical field

The utility model belongs to the technical field of clothes dryers, in particular to a sealing structure of a clothes dryer and a clothes dryer having the same.

Background technique

The dryer or the washing and drying machine comprises a drying cylinder and a drying air duct, and the hot air is sent into the drying to dry the clothes through the drying air duct, and the drying air duct supplies air from the front opening of the outer cylinder; A window pad is arranged between the tube and the front plate of the box body, that is, a window pad at the door body, and a window pad air inlet portion which is sealed and connected with the air outlet of the air duct is arranged on the window pad, so that the wind in the drying air passage passes through the wind. Pass the air outlet, enter the window mat into the wind, and then enter the drying.

In order to ensure the sealing between the air outlet and the air inlet of the window mat, the air inlet of the window mat is set on the outer side of the air outlet, and the tube card is fixed on the outer side of the wind inlet. The current pipe clamp is a worm-type locking pipe clamp, that is, the two ends are superimposed and formed into a ring shape, and are set on the outer side of the wind inlet portion of the window pad, and then the screw is tightened by the screw so that the movable end moves to increase the superimposed size and the pipe clamp clamping. Since the wind inlet of the window mat is a rubber material with good stretchability, the fastening movement distance of the movable end is large when the pipe clamp is fastened; the pipe clamp is closer to the screw on the air inlet portion of the window pad which is in contact with the pipe clamp The area rubber has a relatively large expansion and contraction, and the amount of expansion and contraction of the air inlet portion of the window mat that is in contact with the pipe clamp is different, so that the rubber in the region farther away from the screw is subjected to the extrusion deformation, causing the seam to be tight, resulting in a tight seal. The air leakage phenomenon affects the drying efficiency; and the drying hot air blows out from the flash seam during drying, causing the computer board to be defective and affecting the service life of the computer board.
