Alternatively, the panel 20 is provided with a cooking opening, the burner 40 and the heat insulator 73 are completely disposed in the accommodating space 12, and a flame is generated at the cooking opening for cooking.

In this embodiment, as shown in fig. 1, the bearing surface 21 of the panel 20 is provided with at least one set of gas delivery assembly 30 and burner 40. When multiple sets of gas delivery assembly 30 and burners 40 are provided on the bearing surface 21 of the panel 20, multiple cooking zones are provided.

Being different from the situation of the prior art, the application discloses a gas stove. Be equipped with inside and outside first gas mixing chamber and the second gas mixing chamber that is separated by in the combustion portion, and first gas mixing chamber independently communicates first gas mixing pipe, the second gas mixing chamber independently communicates second gas mixing pipe, first gas mixing chamber and second gas mixing chamber mutual noninterference each other, and gas conveying assembly independently provides the gas to first gas mixing pipe and second gas mixing pipe respectively, therefore the gas-cooker can provide the burning zone of multiple different radiuses, and the flame temperature grade of the burning zone of different radiuses also can independently select, thereby can more adapt to the required variety of user to the culinary art condition, and then realize more ideal culinary art efficiency.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
