According to a ninth concept of the present application, since the electronic control module of the second smoke removal module is improved, the controller is configured to: when the concentration value of the oil smoke is not less than the preset value, controlling the first smoke removal module and the second smoke removal module to work; when the concentration value of the oil smoke is smaller than the preset value, the first smoke removal module is controlled to work for a preset time and then work is suspended, so that the oven can intelligently select a smoke removal mode, the power consumption of the oven is reduced, and the oven is enabled to better accord with the environmental protection concept.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
