At this time, the controller 5 controls and is arranged in the communication outer ring. The control valve 6 of the air outlet 302 of the air passage is closed to automatically cut off the gas passing through the air passage of the outer ring of the burner 2, so as to reduce the fire power. If the real-time temperature drops to the minimum value, at this time, the controller 5 controls the control valve 6 disposed at the air outlet 302 connected to the outer ring air channel to reopen to increase the cooking power. If the real-time temperature continues to rise and reaches the highest value, the control valve 6 arranged in the main air intake pipe 4 is controlled to be closed, so as to automatically switch the gas of the entire cooker, thereby improving the use safety of the cooker.

Further, step S6 is also included: continuously judging whether the gas valve 3 is closed, if so, control all control valves 6 to close, and if otherwise, return to step S4.

Specifically, the gear position detection device continuously detects whether the left gas valve 3 is in the 0th gear or the closed gear. If the user manually closes the left gas valve 3, the controller 5 closes all control valves 6, cuts off the gas supplied to the cooker, and stops combustion.
