Abstract
The invention provides a washing machine door lock and belongs to the technical field of washing machine door locks. The washing machine door lock comprises a door hook, a lock shell, a rotating piece, an elastic rotating piece restoring piece, a lock catch, a lock matching mechanism and lock catch unlocking mechanism. When a washing machine door is closed, the door hook is inserted into the lock shell, the rotating piece is driven by the door hook, the lock matching mechanism guides the lock catch to move from a lock catch restoration position to a lock catch locking position so as to block on a returning path of the rotating piece, and then the washing machine door is locked. After washing is finished, an electromagnetic driving piece drives the lock catch to move along a direction far away from the lock catch restoration position continuously through the lock catch unlocking mechanism, the lock catch is enabled not to block on the returning path of the rotating piece, the rotating piece returns under an action of the elastic rotating piece restoring piece to enable the door hook to pop out from the lock shell, and then the washing machine door is unlocked. The washing machine door lock has the advantages that the washing machine door can be unlocked through the electromagnetic driving piece, and a handle for pulling the washing machine door no longer needs to be arranged on the outside of a door sheet.
Description
technical field [0001] The invention relates to the technical field of washing machine door locks, in particular to a washing machine door lock. Background technique [0002] The door lock in the fully automatic washing machine is used to lock the door cover of the washing machine to prevent clothing from being thrown out and splashing of water. Pulling the handle on the door cover can open the door of the washing machine and put the clothes to be washed into the washing machine. [0003] Chinese patent document CN104805645A discloses a washing machine door lock, which includes a rotating part, a safety lock block and a locking device. The rotating part is installed in the lock housing and can rotate around a connecting shaft. The rotating part rotates under the action of insertion, and the joint part is combined with the door hook. At the same time, the locking device locks the rotating part, thereby locking the door hook; when the door hook is pulled out, the safety lock b...
