Cooking appliances and their doors

Abstract

The invention relates to a cooking appliance and a door body thereof. The door body of the cooking appliance includes a body, a push-pull part, a rotating shaft and two door hooks. The body is provided with movable holes. The push-pull piece is movably arranged in the movable hole. The rotating shaft is rotatably arranged on the body, the push-pull part is connected with the rotating shaft, and the push-pull part is used to drive the rotating shaft to rotate. Two door hooks are arranged on the rotating shaft at intervals. Before opening the door, the rotating shaft can be driven to rotate through the push-pull piece, and the rotating shaft drives the door hook to move accordingly, so that the door hook is separated from the switch contact of the micro switch. Disconnect the power supply, stop supplying power to the magnetron, that is, the magnetron stops generating microwaves, and then the door of the cooking appliance can be opened. On the contrary, after closing the door, the micro switch is connected, and the cooking appliance can work normally again. In this way, it is beneficial to prevent the generation of microwaves at the moment of opening the door, so as to improve the safety performance.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a cooking appliance and a door body thereof. Background technique [0002] Cooking appliances, especially cooking appliances with microwave heating functions, such as microwave ovens with simple microwave heating functions, microwave grills with heating tube grilling functions, micro steamers with steam heating functions, or all-in-one micro steaming and grilling functions, the following Take a microwave oven as an example. Microwave ovens use magnetron to energize to generate high-frequency microwaves to heat food. If high-frequency microwaves leak out, they will hurt the human body, so it is necessary to prevent microwaves from leaking out. In traditional microwave ovens, a plurality of micro switches are usually arranged on the box near the door, and a door hook is arranged on the door corresponding to the position of the microwave switch. Wherein, when the doo...

Problems solved by technology

However, limited by the existing micro switch structure, the existing microwave oven is still powered on and working at the moment the door is opened, and microwaves will leak out of the door at this moment, causing harm to the human body, and the safety performance is low
