Damping device and washing machine

Abstract

The invention provides a damping device and a washing machine. The damping device comprises a shell, a rotating shaft and a damping part; the damping part is arranged in a cylindrical body; the damping part comprises a first damping end and a second damping end; and the first damping end and the second damping end respectively form damping with the shell and the rotating shaft. Through arrangementof the damping part, when the rotating shaft achieves a relative rotating tendency relative to the damping part, interactive friction force can be generated between the rotating shaft and the first damping end to damp rotation of the rotating shaft; under driving by the first damping end, the second damping end achieves a rotating tendency relative to the cylindrical body, so that interactive friction force is generated between the second damping end and the cylindrical body to damp rotation of the second damping end; in the use process of the damping device, damping force for damping rotation of the rotating shaft can be generated; and the damping device is simple in structure, lower in cost, stable in performance and low in failure rate.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to an upper cover damping structure and a washing machine with the damping structure. Background technique [0002] On the pulsator washing machine, in order to prevent the upper cover from falling too fast, there will be a knocking sound or the user will be pinched. At present, the washing machine is generally equipped with an oil-type damper for slowing down the falling speed of the upper cover; the oil-type damper can provide a stable damping force during the closing process of the upper cover, and the damping effect is also better. However, there is a certain free angle in the oil damper, and the damping effect can only be produced after the upper cover is raised to a certain angle. If the upper cover moves within the free angle range, it will still fall rapidly, causing a safety hazard; The damping performance will be significantly affected by the increase...

Problems solved by technology

However, there is a certain free angle in the oil damper, and the damping effect can only be produced after the upper cover is raised to a certain angle. If the upper cover moves within the free angle range, it will still fall rapidly, causing a safety hazard; The damping performance will be significantly affected by the increase and decrease of the temperature. When the temperature is high, the damping force will decrease, which will affect the damping effect on the upper cover; and the price of the oil damper is higher, which increases the cost.
