Infrared temperature-test sensor is monitored as non-contacting temperature information and inputted, while gathering temperature according to the sensor in control software
Degree information is controlled output to the blower fan of range hood to realize that the blower fan of range hood is controlled automatically as air-blower control strategy
System.Blower fan is stopped at normal temperatures；In higher temperature, the operation of blower fan low speed；Just transported at full speed when temperature exceedes certain limit
Sector-style machine, produces maximum air draft ability；Such as long-time thermo-field thoery can be alarmed while sufficient blower fan is driven with " blowing a whistle ", be prevented
Only high oil temperature or cooking stove sky burn.In addition infrared temperature-test sensor should be arranged on range hood bottom, add towards food is cooked
The cooking stove direction of heat.For being equipped with an infrared temperature sensor above each gas-cooker for double stove range hoods, use
Situation is cooked in monitoring each cooking stove simultaneously, strategy uses "AND" logic judgment condition, i.e. temperature control blower condition during judgement
Relative with reference to 2 infrared temperature-test sensor monitorings is high progress.In addition patent range hood of the present invention increase by one " it is automatic/
Aptitude manner switching push button is controlled manually ", oil suction press blower fan automatic control function can be realized by button " automatic " state,
Also by button " manual " state range hood Traditional Man can be kept to control exhaust blower work wind speed.
Environmental Kuznets Curves during using the present invention relates to intelligent range hood to food process, automatically and intelligently can add according to food
Warm status judges that flue gas generating state produces control strategy.Smoke absorption effect can be ensured with suitable strength control fan operation
In the case of i.e. energy-conservation can reduce fan noise again, be avoided that after end of cooking that shutdown does not cause the meaningless work of blower fan and energy in time again
Source is wasted.In addition sensor contacts can be avoided by substituting conventional contacts type temperature sensor using non-contacting infrared temperature sensor
Pollution, from cleaning, convenient use and maintenance.
