Embodiment
See Fig. 1, a kind of air-conditioning draught fan increases shelves arrangements for speed regulation, include printed circuit board (PCB) 1, printed circuit board (PCB) 1 is welded with respectively bidirectional triode thyristor 2, bidirectional trigger diode 7, electric capacity 6, resistance 3 and terminal 4, bidirectional triode thyristor 2, bidirectional trigger diode 7, electric capacity 6, between resistance 3 and terminal 4, connects to form circuit by the deposited copper wire on printed circuit board (PCB) 1; The back side of printed circuit board (PCB) 1 is provided with and supports 5 for fixing insulated column.
In the present invention, printed circuit board (PCB) 1 is epoxy resin PCB printed circuit board (PCB).
Below in conjunction with accompanying drawing, the present invention is further illustrated:
See Fig. 2, fan speed regulation, namely changes the operating voltage of blower fan.Circuit is primarily of rc phase shifter circuit and bidirectional triode thyristor two-part composition, and R1, R2 and C form rc phase shifter circuit.
Blower fan top gear runs: beaten by power switch S to HIGH end, and hold with OUT due to HIGH end and be communicated with, circuit L-S-HIGH-OUT-MF-N forms path, and power supply L, N hold and be directly added on blower fan MF, and blower fan works under normal line voltage, top gear operation.
Blower fan bottom gear runs: beaten by power switch S to LOW and hold, AC supply voltage is charged to capacitor C by R1, R2, when the voltage rise at capacitor C two ends is to break over voltage a little more than bidirectional trigger diode D, bidirectional trigger diode D and bidirectional triode thyristor SCR successive conductive, circuit L-S-LOW-SCR (T1, T2)-OUT-MF-N forms path, according to SCR angle of flow size, the voltage be added on blower fan MF is the mean value of SCR output voltage, namely the voltage compared with normal line voltage value that blower fan MF two ends apply diminishes, blower fan low cruise.When AC supply voltage zero passage moment, bidirectional triode thyristor SCR turns off voluntarily, and then electric capacity C is charged by reversal of power again, repeats said process.Trigger circuit are operated in alternating circuit, alternating voltage just, negative half period just there will be respectively, negative triggering pulse delivers to the control pole of bidirectional triode thyristor SCR, make pipe just, in negative half period, conducting is once symmetrically, according to the required value of air-conditioning system to the low wind speed of blower fan, regulate R2 resistance value, just determine the charging rate of electric capacity C, also the angle of flow of bidirectional triode thyristor SCR is just determined, the i.e. mean value of SCR output voltage, correspondingly change the alternating voltage on blower fan MF, achieve ACVV, namely the wind speed of blower fan is changed, blower fan bottom gear runs, achieve fan speed regulation.
Above-mentioned is that blower fan increases wind-speed gear (second gear) working principle, if blower fan needs to increase wind-speed gear again, only needs to increase gear terminal and electronic circuit more on this basis, by that analogy.
The present invention has effect air-conditioning draught fan being played to increase wind-speed gear, effectively can solve air-conditioning single speed blower fan and only have one grade of wind speed, the problem that several gear wind speed uses can be become, capture a difficult problem of knowing clearly in design, meet the requirement of client to comfort level, and economical and practical, safe and reliable, be convenient to install.
See Fig. 1-3, the present invention is supported 5 by insulated column and is fixed on the panel beating of air-conditioning, terminal 4 is electrically connected with air-conditioning draught fan 9 and switch 8.
After switching on power, beaten by power switch S to HIGH end, hold with OUT due to HIGH end and be communicated with, circuit L-S-HIGH-OUT-MF-N forms path, and power supply L, N hold and be directly added on blower fan MF, and blower fan works under normal line voltage, top gear operation.
Power switch S is beaten to LOW and hold, AC supply voltage is charged to capacitor C by R1, R2, when the voltage rise at capacitor C two ends is to break over voltage a little more than bidirectional trigger diode D, bidirectional trigger diode D and bidirectional triode thyristor SCR successive conductive, circuit L-S-LOW-SCR (T1, T2)-OUT-MF-N forms path, according to the size of the SCR angle of flow, the voltage be added on blower fan MF is the mean value of SCR output voltage, namely the voltage compared with normal line voltage value that blower fan MF two ends apply diminishes, blower fan low cruise.When AC supply voltage zero passage moment, bidirectional triode thyristor SCR turns off voluntarily, and then electric capacity C is charged by reversal of power again, repeats said process.Trigger circuit are operated in alternating circuit, alternating voltage just, negative half period just there will be respectively, negative triggering pulse delivers to the control pole of bidirectional triode thyristor SCR, make pipe just, in negative half period, conducting is once symmetrically, according to the required value of air-conditioning system to the low wind speed of blower fan, regulate R2 resistance value, just determine the charging rate of electric capacity C, also the angle of flow of bidirectional triode thyristor SCR is just determined, the i.e. mean value of SCR output voltage, correspondingly change the alternating voltage on blower fan MF, achieve ACVV, namely the wind speed of blower fan is changed, blower fan bottom gear runs, achieve fan speed regulation.
