Document Type and Number:
WIPO Patent Application WO/2022/105728
Kind Code:
A1
Abstract:
Disclosed in the present invention are a clothing treatment device and a control method, the clothing treatment device comprising: a drum, a plurality of drainage openings being disposed on the drum, and a centrifugal drainage valve being disposed respectively at each drainage opening; after the rotation speed of the drum exceeds a set value, the centrifugal drainage valves are driven by centrifugal force to open the corresponding drainage opening; and the drum rotation speed set value corresponding to at least one centrifugal drainage valve opening a drainage opening is different to that of other centrifugal drainage valves. The present arrangement enables the drum of the clothing treatment device to respectively drive different numbers of centrifugal drainage valves to open at different rotation speeds, such that the clothing treatment device can correspondingly adjust the number of opened drainage openings of the drum just by adjusting the rotation speed of the drum, thereby achieving the effect of correspondingly adjusting the drainage flow rate of the non-porous drum of the clothing treatment device.
