The household appliance may be a dishwasher, a steam box, an oven, a microwave oven, or a steaming and baking all-in-one machine, and the lock is applied to the dishwasher as an example.

Referring to fig. 1, 2 and 3, the latch 100 is used to mount the latch 100 to a dishwasher, namely: the locking device and the holding device are mounted on the dishwasher, and specifically, the lock case 210 and the driving element 310 are both mounted on the dishwasher, for example, the body 400 or the door 500 of the dishwasher, please refer to fig. 1 and 2, and the lock case 210 and the driving element 310 are both mounted on the body 400 for the following description.

When the door body 500 is closed, the door body 500 is clamped by the bolt 220 always having a tendency of protruding out of the lock case 210. When the dishwasher works, the driving element 310 drives the retaining element 320 to move, so that the retaining element 320 locks the state that the bolt 220 protrudes out of the lock shell 210, and the door body 500 is prevented from being opened accidentally when the dishwasher works; when the dishwasher is not in operation, the driving element 310 drives the retaining element 320 to move, so that the retaining element 320 unlocks the state that the bolt 220 protrudes out of the lock case 210, and the bolt 220 can move relative to the lock case 210, so that a user can open the door body 500.

In conclusion, the state that the bolt 220 protrudes out of the lock case 210 can be locked when the dishwasher works, so that the door body 500 is prevented from being opened accidentally, and the use safety of the dishwasher is improved; the state that the latch bolt 220 protrudes out of the lock case 210 can be unlocked when the dishwasher does not work, so that the door body 500 can be opened conveniently. Therefore, the lock 100 improves the use safety on the basis of ensuring the normal opening and closing of the door body 500 of the dish washing machine, and relieves the technical problem that the dish washing machine in the prior art has the potential safety hazard that the door body 500 is accidentally opened when the dish washing machine is used for washing tableware.

Preferably, referring to fig. 3, a lock groove 510 matched with the latch bolt 220 is formed on the door body 500, when the door body 500 is closed, a portion of the latch bolt 220 protruding out of the lock case 210 is disposed in the lock groove 510, and the latch bolt 220 is always clamped in the lock groove 510 with a tendency of protruding out of the lock case 210, so that the latch bolt 220 is clamped in the door body 500.

Preferably, with continuing reference to fig. 4 and with reference to fig. 2, in the present embodiment, the lock case 210 includes a first case 212 and a cover 213 connected to the first case 212, wherein a lock cavity 211 is formed in the first case 212 and the cover 213, an elastic element 230 is disposed between the latch 220 and the cover 213, and the elastic element 230 is used to make the latch 220 always have a tendency of protruding out of the lock case 210 through the opening.

Optionally, the elastic element 230 is a spring or a spring plate, and one end of the elastic element 230 along the elastic direction is connected to the cover 213, and the other end is connected to the latch 220.

It should be noted that the elastic member 230 makes the bolt 220 always have a tendency to protrude out of the lock case 210 through the opening. With such an arrangement, when the door body 500 is closed, the elastic member 230 can drive the latch bolt 220 to tightly clamp the door body 500; when the dishwasher does not work and the door 500 needs to be opened, the elastic pretightening force of the elastic member 230 can be overcome through the external force, so that the latch bolt 220 retracts into the lock cavity 211, the limiting effect on the door 500 is lost, and the door 500 can be opened. It should be noted that the above external force action may be a force applied to the latch bolt 220 by the door 500 when the user opens and closes the door 500.
