Abstract

The invention provides a drum type washing and drying machine, which can prevent the washing powder foam from entering the heating device and the blowing device in the blast heating channel even when the generation amount of the washing powder foam is abnormal, thereby preventing the generation of the washing powder foam. odor, to ensure the reliability of the heating device and blower device. Which is provided with: a water tub (3) elastically supported in the main body (1) and provided with a rotating drum (4) inside; Then, it returns to the rotating drum again, and a blast heating channel (18) with a blast fan (23) is arranged inside. A sealing member (26) is provided on the coupling portion between the blast heating passage and the circulation passage (22), and the sealing member rotates in conjunction with the driving of the blast fan, so that the coupling opening portion can be opened / closed. The closure element does not create resistance to the drying airflow, and at the same time prevents the intrusion of foam during washing.

Description

technical field [0001] The invention relates to a drum-type washer-dryer that performs various processes such as washing, rinsing, dehydration, and drying in a rotating drum whose rotating shaft is in a horizontal or inclined direction. Background technique [0002] In the existing drum-type washing and drying machine, the rotating drum is made into a cylindrical shape with a bottom, and the wall surface of the drum is provided with many through holes for water and air to pass through. The direction of inclination is set in the water tub, which can be rotated under the drive of the motor. On the front side of the tub, there is a clothes inlet and outlet that can be opened or closed by the machine door. After the laundry is put into the rotary drum from the clothes inlet, the water is added to the tub, drained, and rotated by the rotation of the drum. Control, can complete washing, rinsing, dehydration and other strokes. [0003] In addition, by forming a circulation blowin...
