The types of washing machines on the market are increasing as the washing demands of the user market are increased, and the safety problem of the washing machine is a problem which cannot be ignored. Aiming at the safety problem of the washing machine in the washing process, a plurality of washing machine manufacturers select a door lock with safety to play a certain protection role so as to protect the safety of users and children in the washing process. The safety door lock has a certain effect, but the use habit of market users is a problem, so that a lot of users can dump water, washing additives and the like onto the bolt of the clothes door lock in the process of washing clothes. The bolt of the washing machine door lock is generally horizontally arranged, so that water or washing additives and the like can enter the lock body of the door lock along the smooth bolt, and the risks of short circuit damage, even fire and the like of the door lock are easily caused.

Current washing machines can be broadly divided into two categories: pulsator type washing machines and drum type washing machines. The door of the pulsator washing machine is generally installed on a control panel seat which is provided with a clothes input opening upwards. Due to the problem of the operation habit of the user, water and/or washing additives are left on the upper surfaces of the control panel seat, the upper cover and the like. The remained water, washing additives and the like can flow to the bolt along the surface of the control panel seat, and then can enter the lock body of the door lock along the smooth bolt, and the risk of short circuit damage, even fire and the like of the door lock can be caused.

In addition, after the washing machine is powered on, the lock tongue of the door lock extends out and is clamped into the lock hole of the closed upper cover of the pulsator washing machine, and the upper cover of the washing machine cannot be opened due to the clamping position of the lock tongue, so that the upper cover is locked in the washing process, and a good protection effect is achieved. However, when the door lock is protected, once water or detergent contacts with the bolt, the water, detergent and the like on the bolt can enter the lock body of the door lock due to the driving of the telescopic moving bolt in the process of locking or unlocking the door along the horizontal bolt. Once the water, detergent additives and the like flowing into the lock body accumulate to a certain amount, the water, detergent additives and the like flowing into the lock body touch electrified components in the lock body, so that the problems of the fault of the lock body and the like are solved, and even the risk of fire is brought.

The present invention has been made in view of this situation.

The above embodiment is described by taking a pulsator washing machine as an example, but the washing machine in the embodiment of the present invention may be any one of the existing washing machines, for example: drum type washing machines, and the like. The door cover of the drum-type washing machine is generally arranged at the front side, and is turned to the front side of the washing machine to be opened, a door lock 3 is arranged on the front side plate of the washing machine, and a bolt of the door lock is horizontally arranged in a telescopic manner to correspond to the locking door cover; similarly, a lock body 4 of the door lock is fixedly arranged on a front side plate of the washing machine, and a telescopic bolt 5 is arranged on the lock body 4; the end face 9 of the telescopic end 8 of the bolt 5 is an inclined plane which inclines from top to bottom along the extending direction of the bolt 5, so that water sliding from the front side plate, the door cover and the like of the washing machine onto the bolt can still be realized, the washing additive is equal to the bolt phase separation, and the water and the washing additive are prevented from flowing into the lock body 4 along the bolt 5, so that the lock body is prevented from generating faults and the like (not noted in the attached drawings).

Meanwhile, although the above embodiment only describes the technical solution of the door lock 3 as the locking structure of the door cover 1 of the washing machine, it is conceivable for those skilled in the art that the above door lock 3 as the locking structure of other openable and closable cover bodies of the washing machine still belongs to the protection scope of the present application, for example: the door lock 3 is used for locking a box cover of a detergent box of the washing machine, and is used for locking a decorative cover of a thread scrap filter chamber of the washing machine.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
