Cam assembly of push-type door lock, push-type door lock and washing machine

Abstract

The invention provides a cam assembly of a push-type door lock, the push-type door lock and a washing machine, and belongs to the technical field of door locks. The cam assembly of the push-type doorlock comprises a cam body, a cam accessory and an adsorptive elastic component, wherein the cam body is provided with a rotating shaft rotationally connected to the door lock and a bayonet for snapping a door hook; the cam accessory is connected to the cam body through a bolt in a sliding manner; the sliding direction of the bolt is outside a tangent of the rotating shaft; the adsorptive elastic component is connected with the cam body and the cam accessory respectively and is provided with a partial pressure for keeping the cam body and the cam accessory far away from each other. When the camassembly is driven by the door hook to rotate, the cam body and the cam accessory slide relative to each other so as to push elastic deformation of the adsorptive elastic component; when an operatorpushes a door panel, an adsorptive force generated by the cam assembly can be felt and a pushing force on the door hook can be reduced in advance, so as to avoid excessive pushing of the cam assembly.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a cam assembly of a push-type door lock, a push-type door lock and a washing machine. Background technique [0002] The push-type door lock drives the door hook to snap into the cam through the rotation of the cam, and then locks the cam through the cooperation of the lock to keep the cam in the locked position. When unlocking, the lock catch is electrically driven to move, so that the lock catch locks the cam, and the cam rotates toward the unlocked position under the action of the torsion spring, so that the door hook can be drawn out. [0003] Push-type door locks are commonly used on the door of drum washing machines. Among the existing push-type door locks, a washing machine door lock disclosed in Chinese patent document CN107245845A includes a rotating part and a lock, and the rotating part passes through a connecting shaft. It is elastically connected to the torsion sp...

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the push-type door lock in the prior art. When locking the door, it is necessary to maintain a relatively large force to push against the door panel, thereby providing a kind of lock when the cam is about to be locked. A cam assembly capable of generating an attractive force that promotes the rotation of the cam toward the locked position prior to locking and a push-type door lock
