Technical Field

The invention relates to the technical field of steaming and baking equipment such as an integrated stove and an electric oven, in particular to a cooling system of a box body of the integrated stove or the electric oven.

Background

The electric oven is a common electric appliance in European and American families, and is gradually becoming a main electric appliance in kitchens of China along with the increase of communication between the east and the west. For preventing that the overheated damage that causes the cupboard of electric oven box, can load cooling system on the roof of box, can discharge damp and hot gas in cooling system's the air outlet, for avoiding the erosion of steam to the cupboard, the air outlet setting of current electric oven is between control panel and door plant. Although the damp and hot air is blown to the human body, the operation time required by the electric oven is not long, and the electric oven leaves for a long time after the operation of the electric oven is set before the electric oven starts, so that the influence on the human body is avoided. In addition, the door plate with the two-layer structure is arranged, the outer door plate is in contact with air, and the food can be cooled quickly after being baked by the electric oven, so that scalding is prevented.

In order to make the kitchen structure more reasonable and make the electric oven better adapt to the Chinese families, technical personnel in the field develop an integrated cooker which combines the electric oven with a gas cooking bench and a smoke exhaust ventilator and arranges the electric oven under the gas cooking bench. However, as kitchen staff need to operate the gas stove for a long time, if the electric oven adopting the cooling system is started at the same time, damp and hot gas can directly blow to the crotch of the kitchen staff, and the crotch is wet after a period of time, which causes adverse effects on human skin; in addition, in the process of baking food by the electric oven, the temperature of the outer-layer door plate is higher, so that people are easily scalded, and improvement is urgently needed.

Disclosure of Invention
