[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of kitchen utensils, in particular to a high-efficiency hot air cooking device.

[ background ] A method for producing a semiconductor device

The heating device of the cooking appliance (such as an air fryer) is usually arranged at two positions, namely, the heating device is arranged on the pot cover, so that the cooking appliance can cook in different states by replacing different pot covers. The other is to arrange the heating device at the lower part of the pot body to simplify the structure of the pot cover, reduce the weight of the pot cover and facilitate the taking and placing of users.

For cooking appliances having a heating device disposed at the lower part of the pot body, there are generally two heat flow ways in the cooking cavity.

One way is that heat is blown to the pot cover by a hot air fan of the heating device, and hot air collides with the pot cover to change the flow direction, flows downwards, enters a container containing food, and heats the food. In this heat circulation manner, the flow path of the hot wind before it is blown to the food is long, and the heat loss is severe, so that the heating efficiency is low.

Another way is to open a hole on a container containing food, and heat passes through the hole on the container by a hot air fan to enter the container to heat the food, so that the utilization rate of the heat is high, and the method is widely applied. However, due to the holes, hot air can enter the container and also can flow back to the heating device from the container, the hot air in various directions collides, turbulence is easy to occur, and hot air circulation cannot be normally performed.

In addition, the food itself or grease generated from the food during cooking blocks the holes of the container, so that the hot air cannot flow back to the hot air fan through the holes after heating the food, and the hot air is circulated and accumulated in the container, thereby consuming a long time for heating and affecting the taste of the food during cooking.
