For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] like Figures 1 to 9 As shown, the utility model provides a double-layer oven A, comprising a housing 1, an electric oven 2, a gas oven 3, and a controller 4. The electric oven 2 comprises an electric heating component. The gas oven 3 comprises a combustion heating component. The electric oven 2 and the gas oven 3 are arranged vertically, and the electric oven 2, the gas oven 3 and the controller 4 are all installed in the housing 1. The controller 4 is electrically connected to the electric heating component and the combustion heating component respectively to control the electric heating component to start or stop heating, and to control the combustion heating component to start or stop heating.

[0033] In the utility model, since the electric oven 2 and the gas oven 3 are configured at the same time, the user can choose one or activate both the electric oven 2 and the gas oven 3 according to the needs, thereby enriching the user's usage options; in addition, since the heat sources of the electric oven 2 and the gas oven 3 are different, when the electric oven 2 and the gas oven 3 are activated at the same time, there will be no significant increase in electricity consumption, thereby ensuring the safety of electricity use, and the double-layer oven A in the present application is more energy-efficient because a gas oven 3 replaces an electric oven 2 in the background technology; furthermore, the gas oven 3 uses gas heating to heat up quickly, which can meet the demand for faster heating and has higher baking efficiency.

[0034] like Figures 1 to 3 As shown, in one embodiment, the electric oven 2 is located above the gas oven 3, and the controller 4 is located above the electric oven 2. In this way, the controller 4 can be away from the gas oven 3 which emits a lot of heat during operation, thereby extending the service life of the controller 4.

[0035] In another embodiment, the electric oven 2 is located below the gas oven 3, which can still enrich the user's usage options, reduce power consumption, improve electricity safety, and meet the use needs of rapid heating.
