In the present embodiment, as shown in fig. 2, the combustor 40 includes a combustion section 41 and a gas mixing pipe 43 that communicates with the combustion section 41.

For example, as shown in fig. 7, a user may cook using the combustion area of the first mixing chamber 411 independently; alternatively, as shown in fig. 8, the user may cook using the combustion area of the second mixing chamber 412 independently; or in combination with fig. 7 and 8, the user uses the combined combustion area of the first mixing chamber 411 and the second mixing chamber 412 to cook, so that the requirements of the user on the diversity of the combustion areas in cooking can be more adapted.

The gas delivery assembly 30 provides the gas to the first gas mixing pipe 431 and the second gas mixing pipe 432 independently, and thus the flow rate of the gas to the first gas mixing pipe 431 and the second gas mixing pipe 432 can be changed by changing the gas delivery assembly 30, so that the flame temperature levels of the combustion areas of the first gas mixing chamber 411 and the second gas mixing chamber 412 can be regulated and controlled independently, and a user can select the flame temperature levels of different combustion areas independently when using the gas delivery assembly.

For example, when a user uses only the combustion region of the first air mixing chamber 411, the flame temperature level provided by the first air mixing chamber 411 can be adjusted by adjusting the amount of gas flow supplied thereto; when the user uses only the combustion area of the second air mixing chamber 412, the flame temperature level provided by the second air mixing chamber 412 can be adjusted by adjusting the amount of gas flow supplied to it; when the user uses the combustion areas of the first and second air mixing chambers 411 and 412 at the same time, the flame temperature levels provided by the first and second air mixing chambers 411 and 412 may be different or the same.

Therefore, the gas stove 100 provided by the embodiment can provide different combustion areas, and flame temperature levels of the different combustion areas can be independently selected, so that the gas stove can be more suitable for the diversity of cooking conditions required by users, and further more ideal cooking efficiency can be realized.
