WASHING MACHINE SUSPENDER ASSEMBLY HAVING VARIABLE DAMPING FUNCTION AND WASHING MACHINE USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/119582
Kind Code:
A1
Abstract:
A washing machine suspender assembly having a variable damping function. An upper spring support assembly (4) is slidably mounted on a suspender (1); the upper spring support assembly (4) is provided between a suspender base (2) and a lower spring support (3); the upper spring support assembly (4) comprises: an elastic damping sleeve (5), a first sliding base (6), and a second sliding base (7); the first sliding base (6) and the second sliding base (7) are slidably mounted on the suspender (1); one end of the second sliding base (7) is inserted in the first sliding base (6); both ends of a reset spring (8) press against the second sliding base (7) and the lower spring support (3), respectively. The washing machine suspender assembly having a variable damping function uses the upper spring support assembly (4) having an adaptive damping coefficient, can weaken the centrifugal force in a very short time according to the dehydration load, to keep the inner tub from deviations or to produce only extremely small deviations, and avoid the shaking of a tub body and collision between the tub body and a box body, thereby greatly reducing the noise during dehydration, and thus the washing machine can implement dehydration quietly and stably.
