As shown in
In the present embodiment, the door assembly comprises a door body 100, a controller 200, and a handle 300; a movable door body 100 located in the housing 500 of a cooking apparatus. The controller 200 is fixed on one side of the door body 100 away from the housing 500 and At least one ends of the handle 300 are affixed to the controller 200. The handle 300 operates the door body 100 to open or close the cooking chamber of the cooking apparatus.
In some examples, the cooking apparatus may be an oven or microwave oven or a similar cooking appliance. The cooking apparatus may comprise a housing and cooking components, the housing 500 forms a cooking chamber, the cooking components are located inside the housing, the cooking components may heat a cooking chamber of the cooking apparatus. The housing 500 is provided with an opening connecting the cooking chamber at which the door body 100 is located and the door body 100 can seal such opening. Of course, the cooking apparatuses can be other types of appliances, which is not limited by this implementation.
In the present embodiment, the controller 200 comprises a housing and an integrated control system inside the housing connected to the cooking components for controlling the start, stop, or adjustment of operating parameters of the cooking components. The specific composition of the control system can be determined according to the type of cooking components.
