The utility model discloses technical scheme has following advantage:

1. the invention provides a kitchen appliance comprising: a housing, inside which a working inner cavity is arranged; further comprising: the top door piece is arranged on the shell, a self-locking piece is arranged at one end of the top door piece, and the top door piece is controlled by a driving mechanism to perform linear motion towards or away from the direction of the closed door and rotate relative to the shell; the top door piece is provided with a first position at which the door plate is pushed under the driving of the driving mechanism to open the closed door relative to the shell; and when the closed door is closed relative to the shell, the driving mechanism drives the self-locking piece to rotate to a second position on an opening path of the limiting piece.

The top door piece is controlled by the driving mechanism to perform linear motion close to or far away from the closed door and also performs autorotation, and the autorotation of the top door piece drives the self-locking piece to rotate. The limiting piece is arranged on the door plate, and the limiting piece and the door plate are opened together when the door plate is opened. The self-locking piece sweeps through the opening path of the limiting piece in the rotating process, so that the self-locking piece is switched under the state that the limiting piece is prevented from being opened or the limiting piece is allowed to be opened along with the rotation of the top door piece. When the self-locking piece allows the limiting piece to pass through, the top door piece is located at the first position. When the kitchen ware works, the interior of the kitchen ware is usually in a high-temperature environment, the top door piece is located at the second position, and the self-locking piece prevents the limiting piece from moving, so that the closed door is prevented from being opened. Prevent the kitchen ware from being opened by misoperation when the kitchen ware works. After the kitchen utensils and appliances finish the food, because inside high temperature environment still can maintain a period of time, top door spare when this scheme is doing the action of top door, and the hindrance that the self-locking piece opened the sealing door along with top door spare rotates and withdraws gradually. After the self-locking piece rotates to completely loosen the obstruction of the limiting piece, the top door piece continues to be close to the limiting piece and abuts against the limiting piece, and therefore the closed door is opened. Thereby realize relieving the auto-lock simultaneously and pushing up the closed door and open, the high temperature in the kitchen utensils and appliances this moment is to external diffusion, and the user is not near kitchen utensils and appliances this moment, and when the closed door was opened, the user was close to kitchen utensils and appliances again, when preventing to open the work inner chamber of kitchen utensils and appliances suddenly, high temperature direct contact user.

2. According to the kitchen equipment provided by the invention, when the top door piece is located at the second position, the self-locking piece is located between the door plate and the limiting piece.
