Title:
WASHING MACHINE LEG HAVING AUTOMATIC LEVELING FUNCTION AND WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/032689
Kind Code:
A1
Abstract:
A washing machine leg (800) having an automatic leveling function and a washing machine. The washing machine leg (800) comprises: a protective sleeve (500); an adjustable leg (300) provided within the protective sleeve (500) and capable of axially moving relative thereto; and a flexible body component (200) provided within the adjustable leg (300) and used for accommodating a hydraulic medium. One extremity of the flexible body component (200) is limited and mounted within the protective sleeve (500); the other extremity serves as a telescoping extremity acting on the adjustable leg (300). The telescoping extremity of the flexible body component (200) extends or retracts under the effect of the hydraulic medium to drive the adjustable leg (300) to move axially and thereby implementing automatic leveling. The washing machine leg (800) has the hydraulic medium filled in the leg on the basis of the principle of hydraulics; with respect to different pressures applied to the leg, the leg can automatically make adaptive adjustments owing to the fluidity of the hydraulic medium; also, the hydraulic medium is held within the sealed flexible body component (200), the flexible accommodating body is placed within the adjustable leg (300), effectively solved is the problem of hydraulic medium leakage, thus ensuring the working stability of the leg.
