The second technical problem to be solved by the utility model is to provide a household appliance applying the door lock structure aiming at the current state of the art.

The technical scheme adopted by the utility model for solving the first technical problem is as follows: a door lock structure for a home appliance includes

A moving rod which is movably disposed on an appliance body of the home appliance along an axial direction thereof;

the lock rod is arranged on a door body of the household appliance and is provided with a lock hole in which the first end of the movable rod can be inserted;

the movable rod is characterized in that the second end of the movable rod is provided with a handle part used for holding to control the axial movement of the movable rod.

In order to facilitate the pushing of the moving rod by a user, the moving rod is a screw rod, the door lock structure further comprises a positioning plate, a threaded hole is formed in the positioning plate, and the screw rod penetrates through the threaded hole and is in threaded connection with the threaded hole. Therefore, the user can realize the axial movement of the movable rod by rotating the handle part, and the operation is more convenient.

In order to prevent the moving rod from moving excessively and puncture the electric appliance main body or the door body, the door lock structure further comprises a limiting piece capable of limiting the moving stroke of the moving rod towards the lock hole.

Because the movable rod is rotationally lifted, the limiting piece directly acts on the movable rod, and phenomena such as distortion possibly occur, so that the limiting plate is further arranged between the positioning plate and the lock rod, the movable rod can rotationally pass through the limiting plate, the movable rod is fixed relative to the limiting plate in the axial direction, and the limiting piece acts on the limiting plate. Therefore, the limiting piece acts on the limiting plate and does not directly act on the moving rod, because the moving rod is fixed relative to the limiting plate in the axial direction, and the limiting piece can also play a limiting role on the moving rod.

In order to enable the movable rod to be fixed relative to the limiting plate in the axial direction, the upper surface of the limiting plate is abutted to the pressing plate, and the movable rod is provided with a caulking groove for locally embedding the pressing plate.

The limiting piece can have various structural forms, such as a limiting block, and the limiting piece is an elastic piece which acts on the limiting plate and enables the limiting plate to always move in a direction far away from the lock hole.

Preferably, the door lock structure further comprises a fixing rod fixedly arranged at the top of the electric appliance main body, a sleeve is sleeved on the fixing rod, a through hole through which the sleeve can pass is formed in the limiting plate, an abutting part capable of abutting against the lower surface of the limiting plate is arranged at the bottom of the sleeve, and the elastic piece acts on the abutting part.

Preferably, the locating plate is fixedly arranged at the upper end of the fixing rod, and the fixing rod simultaneously plays a role of locating the locating plate.

The utility model solves the second technical problem by adopting the technical proposal that: the household appliance with the door lock structure is characterized in that: the electric appliance comprises an electric appliance main body and a door body, wherein an inner cavity with one side open is formed in the electric appliance main body, the door body is movably arranged at the opening of the electric appliance main body to open and close the inner cavity, the moving rod is arranged on the electric appliance main body, and the lock rod is arranged on the door body.

In order to further improve the working safety of the household appliance, the front side of the inner cavity is open, the movable rod is arranged at the top of the appliance main body, the movable rod vertically extends, and the handle part is arranged at the top of the movable rod. Thus, the movable rod is positioned at a higher position, and is not easily contacted by children.

In the above scheme, in a state that the door body closes the electric appliance main body, the part of the lock rod with the lock hole is positioned above the electric appliance main body.

The household appliances can be steam boxes, ovens and the like, and also can be cleaning machines, and the inner cavity is a washing cavity.

Compared with the prior art, the utility model has the advantages that: the movable rod is arranged, the handle part is arranged on the movable rod, and the movable rod is controlled to move by manually holding the handle part, so that the first end of the movable rod is inserted into the lock hole or is separated from the lock hole, and as the handle part is required to be manually controlled, the moving difficulty of the movable rod is increased for children, namely the difficulty of opening the door is increased, and the use safety of the household appliance is improved.
