When smoke with a certain concentration enters the smoke collection cavity 11, intermittently emitted infrared rays irradiate the infrared receiving tube through diffuse reflection of smoke particles, the infrared receiving tube converts the infrared rays into light current and then amplifies the light current by the triode VT1, if the voltage of the No. 8 pin of the processor 3 is momentarily lower than half of the voltage provided by the external potentiometer RP to the No. 11 pin, the No. 9 leading-in pin of the processor 3 becomes high level, the electric control board ZLD2 receives electric signals, and the smoke can be recovered to be normal after the smoke disappears for a period of time.

In some embodiments of the invention, in the use of the integrated cooker in the prior art, although the gear can be controlled by a user according to the situation, the arrangement mode only depends on side suction to discharge smoke, and the disadvantage of the arrangement mode is that a large amount of oil smoke generated instantly cannot be completely sucked only depending on side suction in the stir-frying process, and part of the oil smoke can overflow and disperse; therefore, in order to solve the problem, the air inlet 12 is formed in the shell 1 and communicated with the side wall of the smoke collection cavity 11, and the arrangement aims to ensure that a plurality of air inlets 12 are formed in the shell 1 and any air inlet 12 is communicated with the side wall of the smoke collection cavity 11 when the stove is in a stir-frying process because the generated amount of instantaneous smoke of oil smoke is large and cannot be completely sucked only by the prior art, so that the absorption effect of the oil smoke can be improved. In addition, the edge of the air inlet 12 is provided with the optical inductance smoke type sensor, so that the oil smoke is monitored in real time, signals are sent to the central control circuit according to the size of the oil smoke, the central control circuit controls the motor after receiving the signals, the force for absorbing the oil smoke is increased, the oil smoke is absorbed completely, the absorption efficiency of the integrated stove is improved, and the problem that the oil smoke can overflow and disperse is solved.
