With the improvement of people's quality of life, kitchen appliances are becoming more and more abundant, and microwave ovens, ovens, steamers, etc. have gradually become necessary kitchen appliances for family life. The functions of these kitchen appliances are relatively single, and each product has its inherent volume, which needs to occupy a certain space in the kitchen.

The principle of heating food in a microwave oven is to convert electrical energy into microwave energy through a magnetron and then transmit it to the oven cavity, so that a distributed microwave field is formed in the oven cavity. When the food is in the microwave field, the food will absorb the microwave energy and make the food inside and outside are heated at the same time. This heating method has the characteristics of fast heating speed and easy control of heating time for heating soup food, beverages such as milk, food without hard shells, and heating cold dishes and rice; but if it is used for heating steamed bread Steamed buns, steamed buns and other foods that need to be foamed during the steaming process will cause problems such as "inner hardness" and "dehydration". When eating meat with bones, it will cause an "explosion". In addition, there are also requirements for food containers, such as canned food, porcelain bowls with metal edges, etc. cannot be heated in a microwave oven; Narrow and low utilization. In order to expand the use of microwave ovens and give full play to the advantages of microwave ovens, there are currently many microwave ovens with steam functions. For example, in the technology disclosed in the Chinese patent No. ZL201110231072.3, all of them are microwave ovens with steam functions. To heat food, the steam generated by microwave heating water can be used to steam cook the food. This type of microwave oven needs to place the water container that generates water vapor in the microwave oven cavity, but the volume of the microwave oven cavity is not large. After the special water container is placed, the space is even narrower, resulting in very limited space for steaming and cooking food, so the space utilization rate of the microwave oven cavity is low. In addition, the patent No. ZL200920185932.2 "A Microwave Oven with Steam Function" puts a steamer in the cavity of the microwave oven, and then connects the outlet of the electric steam generator to the steamer through a steam conduit. The steamer used for steaming food is not very convenient to use. In addition, for this kind of microwave oven with microwave heating function and steam heating function at the same time, the sealing structure of the door body assembly is very important, not only to ensure that the microwave will not leak, but also to ensure that the steam will not leak.
