technical field

The utility model relates to the field of cooking utensils, in particular to an electric oven.

Background technique

High, so that the base of the electric oven is overheated and it is easy to aggravate aging and damage, and it is easy to damage the electronic device in the electric oven. Many current electric ovens will have a heat dissipation cavity under the heating component.

On the other hand, the electronic device can also be placed in the heat dissipation cavity to avoid direct contact between the electronic device and the heating element, which can play a certain protective role. However, in the long run After time is used, the air in the heat dissipation chamber is also easily heated to a higher temperature. For this reason, many electric ovens also provide ventilation holes on the outer wall of the base body that communicate with the heat dissipation chamber to make the air in the heat dissipation chamber It can dissipate heat by exchanging with the outside air, but because most of the current electric ovens do not consider the air flow characteristics, and electric ovens are usually used indoors, the air flow is weak, and it is difficult for the hot air in the heat dissipation cavity to generate enough flow to communicate with the oven. The outside cold air is exchanged, and there is also adhesion between the air and the top inner wall of the heat dissipation chamber. The oven will add a heat dissipation fan in the heat dissipation cavity to promote air flow, but this will also increase the cost and volume of the electric oven.
