Description

Ceiling fan time-delay stepless speed adjusting gear

The utility model relates to a kind ofly makes that ceiling fan starts fast, the ceiling fan time-delay stepless speed adjusting gear of automatic stable to the speed regulator institute control rate.

At present, hanging fan governor generally adopts tapped transformer, by changing the size of reactance amount, the ceiling fan motor two ends obtain different voltages to reach the purpose of speed governing, and this speed regulator adjustable range is little, volume is big, weight is big, power consumption is high, stir difficulty and fragile.In addition by the various speed regulator that adopts thyristor and different control circuit to form, though these speed regulators have overcome the shortcoming of reactance speed regulator, but still have very big inconvenient ceiling fan under lower-speed state, to start difficulty and the big shortening of electric current its useful life in the use, starting fast needs certain hour about ten seconds, speed regulator is transferred to the appropriate location from high to low because fan has big inertia again after the startup, is transferred to required speed and is difficult for grasping.

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of speed-regulating range width, volume is little, in light weight, cost is low, power consumption is little ceiling fan time-delay stepless speed adjusting gear are provided.

The purpose of this utility model is achieved in that a kind of ceiling fan time-delay stepless speed adjusting gear, it is by the electric current inductance transformer that is equipped with in control box and the box, the power supply terminal that wiring board that links to each other and Bottom of box body are equipped with constitutes, it mainly is that wiring board is provided with the regulator rectifier circuit unit, the delay electronic switch circuit unit, midget relay and thyristor, and be connected with slide potentiometer and mains switch that control is provided with on the box body, realized by manually starting speed governing more fast for starting the purpose of automatic stable automatically fast, its course of work is the energized switch, ceiling fan starts fast in 10 seconds, and ceiling fan drops on the speed that speed regulator controls automatically after 10 seconds.

Below in conjunction with drawings and Examples the utility model is illustrated in detail.

Fig. 1 is this real Yangxin type schematic appearance.

Fig. 2 is the utility model circuit structure block diagram.

Fig. 3 is the utility model circuit theory diagrams.

Among the figure: 1 control box, 2 mains switch K, 3 slide potentiometer W, 4 electric current inductance transformer B, 5 regulator rectifier circuit unit, 6 delay electronic switch circuit units, 7 midget relay L, 8 thyristor SCR, 9 wiring boards, the low seat of 10 box bodys, 11 power supply terminals.

Shown in Fig. 1-3, a kind of ceiling fan time-delay stepless speed adjusting gear, it is by the electric current inductance transformer B (4) that is equipped with in control box (1) and the box, the power supply terminal (11) that wiring board (9) that links to each other and Bottom of box body (10) are equipped with constitutes, it is characterized in that: in the preceding controllable silicon SCR (8) that is connected to of electric current inductance transformer B (4), it is in parallel after resistance R 7 is connected with potentiometer W (3) and capacitor C 3 with controllable silicon SCR (8), the control utmost point of SCR (8) is connected between potentiometer W (3) and the capacitor C 3, relay contact JK is connected in parallel on controllable silicon SCR (8) two ends, behind electric current mutual inductance power transformation device B (4), be connected to full bridge rectifier D1-D4, be connected to filter capacitor C1 and integrated regulator IC thereafter, resistance R 1, after the R2 series connection, its tie point connects the base stage of triode BG1, resistance R 1, R2, R3 and triode BG1 constitute constant-current source, constant-current source output passing through R4, R5 connects the BG2 base stage, capacitor C 2 is connected on R4, between the R5, other end ground connection, the collector output of BG2 connects the BG4 base stage by diode BG3, and the BG4 collector electrode connects positive source by relay coil L.Power turn-on K switch (2) during work, secondary generation alternating voltage at transformer B (4), through the rectification circuit D1-D4 of Golden Bridge, filter circuit C1, the integrated circuit (IC) voltage stabilizing obtains the 12V direct voltage, at first make the BG4 conducting, relay L (7) has electric current by adhesive JK, make the negative electrode and the short circuit of sun level of controllable silicon SCR (8), provide full voltage to start fast at the ceiling-fan motor two ends, 12V voltage is through R1 on the other hand, R2, G1, the constant-current source that R3 forms charges to C2, charging interval was 10 seconds, at this moment the voltage on the C2 makes switch triode BG2 conducting, BG4 ends, and JK disconnects, and this moment, the ceiling-fan motor both end voltage was controlled by SCR.Adopt slide potentiometer W (3), can control the conducting phase place of SCR, realized stepless speed regulation.

The utility model has the advantages that: 1, whole device adopts that single line advances, single line goes out, and is convenient to Install, can directly substitute the reactance speed regulator; 2, speed-regulating range width, simple to operate saving time, Adopt slide potentiometer to carry out speed governing, more directly perceived, as in the suitable situation of control rate, Only need turn on-switch to get final product; 3, adopt the Current Mutual Inductance transformer, with mains isolation, make whole Individual delay circuit is operated in low-pressure state, guarantees that it is stable, safe and reliable running; 4, Volume is little, in light weight, electric energy loss is little, cost of manufacture is low.
