Abstract
The utility model discloses a wind speed control system of a range hood. The wind speed control system comprises a power supply and a fan which are mutually connected with each other. The wind speed control system also comprises a smoke concentration sensor, a controller and a frequency converter, wherein the smoke concentration sensor transmits the sensed smoke concentration data to the controller, the controller controls the working frequency of the frequency converter according to the received smoke concentration data, and the output power of the power supply is controlled through the frequency converter. By adopting the structure, the working speed of the fan of the range hood can be intelligently adjusted, so that the electric energy can be efficiently saved.
Description
Technical field
The utility model relates to a kind of control system at the smoke exhaust ventilator work wind speed.
Background technology
Smoke exhaust ventilator is the essential items in kitchen, can be evacuated to the oil smoke that cooking produces outdoor, keep the environmental sanitation in kitchen, still, present smoke exhaust ventilator has only one grade of wind speed, but when frying different cuisines, the oil smoke amount that produces is different, the oil smoke of generation more after a little while, it is very big that the wind speed of smoke exhaust ventilator will seem, cause waste of electric energy, have much room for improvement.
The utility model content
The purpose of this utility model is to provide a kind of smoke exhaust ventilator wind speed control system, and it can intelligence regulate the blower fan operating rate of smoke exhaust ventilator, thereby effectively saves electric energy.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of smoke exhaust ventilator wind speed control system comprises interconnective power supply and blower fan; Also comprise smokescope sensor, controller and frequency converter, described smokescope sensor is sent the smokescope data of sensing into controller, this controller is according to the operating frequency of the smokescope Data Control frequency converter that receives, by the power output of Frequency Converter Control power supply.
Above-mentioned controller adopts PLC.
After adopting such scheme, the utility model is by arranging the smokescope sensor, can be in the process of smoke exhaust ventilator work sensing indoor smog concentration in real time, if smokescope is higher, then controller increases the power output of power supply, indoor oil smoke is evacuated to as early as possible outdoor, and when indoor smog concentration hour, then turn down the power output of power supply, save electric energy.
Description of drawings
Fig. 1 is principle schematic of the present utility model.
The specific embodiment
Below with reference to accompanying drawing, the technical solution of the utility model and beneficial effect are elaborated.
As shown in Figure 1, the utility model provides a kind of smoke exhaust ventilator wind speed control system, comprises interconnective power supply and blower fan, and power supply provides operation power for blower fan.
Improvement of the present utility model is: also comprise smokescope sensor, controller and frequency converter, and the indoor smokescope of the real-time sensing of described smokescope sensor, and the smokescope data of sensing are sent into controller; This controller can adopt PLC, described controller is according to the operating frequency of the smokescope Data Control frequency converter that receives, power output by the Frequency Converter Control power supply, when the smokescope data that sense when the smokescope sensor are higher, controller can be heightened the power output of power supply by frequency converter, the blower fan operating rate is accelerated, and can be discharged to indoor smog outdoor as early as possible; And when if indoor smog concentration is low, if also adopt existing wind speed, will cause waste of electric energy, and this case can be turned down the power output of power supply when indoor smog concentration is low, can satisfy the actual needs of extracting oil smoke out, also can save electric energy, kill two birds with one stone.
Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, as to do on the technical scheme basis any change all falls within the utility model protection domain.
