Description

Technical Field

[0001] The utility model relates to the technical field of equipment related to a microwave oven, steamer or oven, and in particular to a door structure which is easy to install and has a heat dissipation air duct. Background Art

[0002] A microwave oven is a kitchen appliance that can both steam and bake food. Its working principle is: in terms of steaming, the working principle and structure of a microwave oven are the same as those of a steamer, which are improved from a steamer, that is, the way of boiling water is changed to using an independent steam generator to generate steam and then transport it to the inside of the machine to steam food; in terms of baking, the heating principle of a microwave oven is the same as that of an oven, both of which use heating tubes to generate heat to bake things, and the configuration and distribution of the heating tubes are the same.

[0003] Currently, most microwave ovens on the market combine microwave and steaming functions to cook food. This method has the advantage of rapid heating with microwaves, while the steaming function prevents moisture from being lost in food.

The design of the door assembly of a microwave oven generally focuses on preventing microwave leakage, but when the oven is working, the temperature of the door surface is generally high, which will lead to a poor user experience. In addition, when the glass of the door assembly is damaged, the entire door assembly must generally be replaced, because the door frame is easily deformed and damaged when disassembled, which will cause the problem of being unable to be used again.
