Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0026] This embodiment proposes a top cover closing buffer device, which can be applied to any household appliance with the top open. It includes a transmission shaft 11, a cable 12 and an elastic structure, wherein the transmission shaft 11 passes through the The rotating shaft 21 rotates to realize the transmission connection with the rotating shaft 21 . The two ends of the cable 12 are respectively the trailing end and the load-bearing end, and the trailing end of the cable 12 is fixedly connected with the transmission shaft 11 for being wound up on the transmission shaft 11 when the upper cover 20 falls. The elastic structure is fixedly connected to the load-bearing end of the flexible cable 12, and is used to generate gradually increasing tensile resistance when the trans...

Abstract

The present invention provides an upper cover closure cushioning device and a washing machine including the same. The cushioning device includes a drive shaft, a flexible cable and an elastic structure; the transmission shaft is used for being drivingly connected with a rotating shaft of an upper cover; a traction end of the flexible cable is connected to the drive shaft, and the flexible cable iswound on the drive shaft when the upper cover drops; the elastic structure is connected to a load-bearing end of the flexible cable, and is used for generating a gradually increasing tensile resistance when the drive shaft receives the flexible cable; the elastic structure comprises a first magnetic member, a second magnetic member, and an elastic member for generating the tensile resistance whenthe first magnetic member and the second magnetic member attract each other. The cushioning device can effectively solve the problem that the existing upper cover falls too fast during the closure process.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to the design of an upper cover closing buffer device. Background technique [0002] Due to the heavy weight of the glass top cover of the existing fully automatic washing machine, problems such as bumping, accidental injury to the user, and loud noise are likely to occur due to the fast drop of the top cover during the closing process. Therefore, the existing top cover closing buffer solution includes: [0003] 1. Grease is added to the rotating shaft of the upper cover. When the rotating shaft rotates, the grease flows from the cavity A into the cavity B, and the flow of the grease is used to generate resistance. Since the performance of the grease is greatly affected by the temperature, the falling speed of the upper cover is likely to be unstable. [0004] 2. Due to the limitation of the structure, the traditional damping structure cannot effectively restrain the accele...
