Background technology
At present, the oil smoke that domestic high residential building pump drainage culinary cuisine produces adopts " fume tube type " (bottom is sealed) design mostly, generally tens of public 1 common flue of user, flue gas is subject to thrust upwards all the time in theory, can make the oil smoke of each subscriber household discharge along common flue, but concentrate operational phase (as cooking the time) when encountering many lampblack absorbers in different floors, a large amount of oil smoke enter common flue, and oil smoke is estimated after motion to bring certain retardation through flue is long, the internal pressure of common flue is increased, thereby have influence on the smoke discharging effect of each subscriber household.
In order to ensure the effect of family's smoke evacuation, generally need to change with the pressure that adapts to common flue by the blower fan exhaust air rate that regulates lampblack absorber, still, traditional range hood rotating speed is normally by manual adjustment, often need user repeatedly to regulate intervention, waste time and energy, and current lampblack absorber gear is more fixing, air quantity output is also fixing, no matter how user's oil smoke amount size changes, and can only select static stall, cannot adapt to practical service environment.
Utility model content
The purpose of this utility model is to overcome the above defect of prior art, and the range hood of a kind of simple in structure, with low cost, stable performance, safe and reliable automatic speed regulation supercharging is provided.
In order to reach above object, the utility model is achieved through the following technical solutions: a kind of range hood of automatic speed regulation supercharging, comprise lampblack absorber housing, display button panel, be arranged at the motor in this lampblack absorber housing and control the main control circuit of this motor speed, the front portion that display button panel is arranged on lampblack absorber housing is independent of main control circuit and is connected with main control circuit by data wire, motor is arranged between lampblack absorber housing air inlet and air outlet and by connecting line and is connected with main control circuit, main control circuit is installed on the top of lampblack absorber housing, the air outlet of lampblack absorber housing is connected to common flue by smoke exhaust pipe, it is characterized in that, in described main control circuit, be provided with two alignment detection circuits, one tunnel is curent change testing circuit, and it is made up of main control CPU module, current of electric acquisition module and operation amplifier module, and current of electric acquisition module is connected to main control CPU module by operation amplifier module, another road is power grid voltage detection circuit, and it is by main control CPU module, electric moter voltage acquisition module and step-down rectifier module, and electric moter voltage acquisition module is connected to main control CPU module by step-down rectifier module.
As preferably, in described display button panel, be provided with automatic speed regulation supercharging module and automatic speed regulation supercharging button, automatic speed regulation supercharging button is connected by connecting line with motor, and automatic speed regulation supercharging module is connected by data wire with the main control CPU module in main control circuit.
Beneficial effect: in the time that common flue pressure changes, the control signal of test circuit changes, main control circuit gathers current signal by current of electric acquisition module and feeds back to main control CPU module by operation amplifier module, and main control CPU module is carried out Data Management Analysis and compared with setting value; In addition, cause that the factor of curent change is except common flue pressure changes, also have grid voltage change to cause, therefore setting up another road is power grid voltage detection circuit, and this alignment detection circuit gathers voltage signal by electric moter voltage acquisition module and feeds back to main control CPU module by step-down rectifier module.
First judge whether electric current departs from setting value, judge and then whether voltage departs from setting value; When electric current departs from and voltage is normal, drive motors rotation speed change; When departing from voltage simultaneously, also departs from electric current drive motors rotation speed change.
