Abstract
An automatic speed adjusting range hood comprises a casing, a ventilation duct, a temperature sensor, a control switch, an inverter, a frequency converter, a motor and a fan, wherein the control switch is mounted on the right side of the front end of the casing, the temperature sensor is mounted on the reverse side of the front end of the casing at the connecting part of the control switch, the output end of the temperature sensor is connected with the input end of the inverter, the output end of the inverter is connected with the frequency converter, the output end of the frequency converter is connected with the motor inside the ventilation duct, the driving shaft of the motor is connected with the fan, the temperature sensor generates signals according to oily fume temperature, the speed of the fan is adjusted through the frequency converter, the rang hood can automatically adjust wind speed according to the size of the oily fume, and the automatic speed adjusting range hood is convenient, quick and efficient.
Description
Affiliated technical field
The present invention relates to lampblack absorber, especially a kind of automatic speed regulation lampblack absorber.
Background technology
Lampblack absorber is the household electrical appliance of the oil smoke that produces for when cooking of exhausting, uses safety, working stability, but lampblack absorber adjusting rotary speed needs manual operation, and not convenient and speed governing button is fragile.
Summary of the invention
In order to address the above problem, the invention provides a kind of automatic speed regulation lampblack absorber.
The technical scheme that technical solution problem of the present invention adopts is:
A kind of automatic speed regulation lampblack absorber, it is characterized in that by shell, ventilating duct, temperature sensor, gauge tap, phase inverter, frequency converter, motor, fan forms, it is positive that gauge tap is installed on shell front end, the temperature sensor of gauge tap connected with outer casing front end reverse side, the output of temperature sensor connects phase inverter input, inverter output is connected with frequency converter, inverter output terminal is connected with the motor in ventilating duct, motor driving shaft connects fan, temperature sensor produces signal according to oil smoke temperature and is converted and be transferred to frequency converter by phase inverter, frequency converter regulates the rotating speed of motor according to input signal, thereby adjusting fan speed, realize automatic speed regulation.
The invention has the beneficial effects as follows that oil smoke function regulates wind speed, convenient and efficient automatically according to oil smoke size.
Accompanying drawing explanation
