The utility model compared with prior art has following features: detect smoke exhaust ventilator by smoke transducer and whether gas leakage occurs, the oil smoke temperature of smoke exhaust ventilator is detected by thermal sensor, and by the rotation speed of the fan of PLC according to the detection Reasonable adjustment smoke exhaust ventilator of the two, and then improve the security in kitchen.
Accompanying drawing explanation
Fig. 1 is the circuit structure block diagram of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
As shown in Figure 1: a kind of induction type control system of cooking fume exhauster, PLC, frequency converter, display, air flow sensor, air quantity transmitter, smoke transducer and thermal sensor is comprised; The output terminal of PLC is connected with frequency converter, display; The input end of PLC is connected with air quantity transmitter, smoke transducer and thermal sensor; The input end of air quantity transmitter is connected with air flow sensor; Frequency converter is connected with the motor of smoke exhaust ventilator.
Control principle is: when smoke transducer has detected gas leakage, and automatic signalling, to PLC, after PLC receives the order of smoke transducer, rotates by controlling power converter output drive motor; When thermal sensor detects that the oil smoke temperature of smoke exhaust ventilator is too high, automatic signalling, to PLC, after PLC receives the order of thermal sensor, rotates by controlling power converter output drive motor; Air flow sensor measures the air quantity that motor exports, and feeds back to PLC by air quantity transmitter, as the power reference regulating frequency converter, thus regulates the size of motor discharge quantity of fan; The air quantity of current smoke exhaust ventilator, oil smoke temperature and gas leakage state are shown by display, facilitate the kitchen personnel of cooking to understand the state of current smoke exhaust ventilator.
In the present embodiment, the model of smoke transducer is MQ-2, the model of thermal sensor is the miniature platinum resistance of WZP-PT100, the model of air flow sensor is YGM303 rhombus air flow sensor, the model of air quantity transmitter is HDP802 micro-pressure-difference transmitter, display is LCD liquid crystal display, and PLC is existing PLC integration module, carries modulus conversion chip etc.
The present embodiment detects smoke exhaust ventilator by smoke transducer and whether gas leakage occurs, the oil smoke temperature of smoke exhaust ventilator is detected by thermal sensor, and by the rotation speed of the fan of PLC according to the detection Reasonable adjustment smoke exhaust ventilator of the two, and then improve the security in kitchen.
