Description

Multifunction energy-saving controller for ceiling fan

The utility model relates to a kind of ceiling fan controller, particularly a kind of multifunction energy-saving controller.

Existing ceiling fan mainly is to use the inductance speed regulator, shortcomings such as power consumption is big, function singleness, external form difference that it has; In addition, be that it has shortcomings such as function singleness, humorous wave interference with simple controllable silicon phase shift speed regulator.Introduced a kind of ceiling fan multifunctional controller in Chinese patent 88206127.5, this controller also is two end AC networks, have speed governing, regularly, three kinds of functions of natural wind simulating.But there are two big deficiencies in it: one, fan speed-regulating is by the single-phase silicon-controlled pressure regulation of capacitance-resistance phase shifting control, the voltage of fan electromotor gained is non sinusoidal wave thus, when especially working in low cruise, wave distortion is serious, and this not only is unfavorable for motor, produced simultaneously humorous wave interference electrical network and other electrical equipment, and the flat ripple inductance L that it is joined cannot be done very greatly because of inductance value, and the effect of improving above-mentioned unfavorable factor is very little.Its two, the reliability of this controller long-term work existing problems, the direct current that its control unit is required, by Ac after full wave rectifier by R3 step-down current limliting voltage regulation filtering again.And in fact when the operation of the long-term maximum quantity of wind of fan, the almost all-wave conducting of its controllable silicon, its pressure drop is very little, and when fan during with minimum wind speed operation, thyristor operating angle is very little, and pressure drop is very big.So, the voltage of its R3 is the 100V(effective value) above big dynamic fluctuation scope, obviously R3 and voltage-stabiliser tube D6 are operated under the condition of very severe, their type selecting is extremely difficult, obtain in this way D.C. regulated power supply as matured product be unpractical it be difficult to provide the direct current (d.c.) of MA level.

The purpose of this utility model is exactly for a change above-mentioned the deficiencies in the prior art, provide a kind of installation the simplest and easy, do not have humorous wave interference, safe and reliable, energy-conservation, ceiling fan multifunction energy-saving controller that cost performance is high, can make ceiling fan have electrodeless adjustment, natural-wind-imitating, sleep wind, regularly, infra-red remote control start and stop function.

The purpose of this utility model is achieved in that

Ceiling fan multifunction energy-saving controller is one and exchanges two-terminal network, by SCR protective circuit (1), zero passage detection switch (2), two-way SCR(3), ac-dc conversion (4), trigger that control (5), speed governing (6), respectively independent voltage stabilizing again (7), infrared remote control are accepted (8), operating switch control (9), regularly (10), natural-wind-imitating (11), sleep wind unit such as (12) are formed.Major technique is characterized as two-way SCR(3) conducting and the EDM Generator of Adjustable Duty Ratio of closing, in its time of closing, the electrical network electric energy is powered to ac-dc conversion (4), and the direct current of ac-dc conversion (4) output is through transferring to each control unit (6), (8), (10), (11), (12) respectively after the independent decoupling voltage stabilizing once more, thereby has guaranteed respectively to control the reliable operation of function.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Accompanying drawing is the circuit theory diagrams of the ceiling fan multifunction energy-saving controller that the utility model proposes.

Below in conjunction with accompanying drawing the utility model is described in further detail: by current-limiting resistance R1, the zero passage switch that isolating transformer B1 and full-bridge rectification and R4 form, in the work when Ac positive pressure half cycle during greater than 10V, its voltage is coupled secondary full wave rectifier again through the R4 current limliting through the R1 current limliting by B1, the signal of its output is forced the T1 saturation conduction, and bidirectional triode thyristor SCR loses trigger signal and closes.When power supply is positive half cycle and value during less than the 10V left and right sides, a little less than its R4 output signal, T1 ends, and SCR can permit conducting; Power supply is that the negative half period working principle is the same.Thereby guaranteed that SCR only just might conducting when supply voltage is positive and negative zero passage, what make that motor obtains is sinusoidal wave.Here the trigger signal of SCR is come the speed governing unit that free IC1 and peripheral components constitute, and it exports the trigger signal of R22 to, is the low frequency oscillation of EDM Generator of Adjustable Duty Ratio, has constituted thus to obtain the galvanic precondition of the nearly 10MA of 12V.The required direct current principle of each control unit is: Ac through the C2 current limliting again by DW1, D2, the C4 voltage stabilizing, rectification, filtering, the direct current of output one fluctuation, because SCR is the on off state that works in dutycycle, when both having made fan run on the fastest wind speed, its every 1-2 in second SCR shut-in time of a sine wave (0.020 second) is arranged, in at this moment, power supply because the motor impedance phase to much smaller, almost be added to regulator rectifier circuit entirely, and guaranteed this moment during the design of this controller system, power supply to C4 go up the duration of charge much smaller than C4 to the load discharge time, make the fast state of controller long-time running guarantee that all the time direct current is arranged on the C4.When running on low speed as for fan, the SCR periodicity shut-in time is longer, and obviously direct current obtains easier.The DC converting unit almost is being to work in the power supply full voltage adds only like this, so the components and parts type selecting is easy, reliable operation.

Because elementary voltage stabilizing output presents the bigger unfavorable factor of fluctuation at work, the control unit in each required DC electrical source all needs voltage stabilizing once more for this reason.Facts have proved that as having lacked this measure this controller will can reliably working.

The specific implementation of the various functions of this controller will be described in detail in detail below:

1, stepless speed regulation: time switch K1 is put " 2 " position, this moment the T2 saturation conduction, D15 is output as low level; Again wind type selector switch K2 is put 1 position, this moment the IC2 non-transformer, its R21 is output as low level; And by the Low Frequency Oscillator of the EDM Generator of Adjustable Duty Ratio that IC1 and peripheral cell constituted, when its output R22 is high level, and when this moment, supply voltage was zero passage, then SCR conducting, fan gets electric operation; When R22 was output as low level, SCR turn-offed.Can regulate the R22 output duty cycle by regulating W1 like this, realize the stepless speed regulation of fan.Because fan is inertia device, in addition during the design duty when oscillation frequency select suitable, so noisy phenomenon when fan will not low cruise occur.Even fan is still when running on gentle breeze so.

2, natural-wind-imitating: K1 is put " 2 " position, wind type selector switch K2 puts " 2 " position.This moment is the T1 saturation conduction when it was exported R21 and was high level at tens seconds oscillator IC2 and period of vibration that peripheral cell constitutes thereof, trigger signal short circuit from the speed governing unit, SCR closes, when otherwise R21 is output as low level, the T1 correspondence is ended, and fan will present suddenly big or suddenly small similar natural wind by speed governing this moment.And the air quantity of this natural-wind-imitating still is controlled by speed governing knob W1, adjusts it and can obtain the most satisfied boundary.

3, sleep wind: K1 still locates " 2 " position, and K2 puts " 3 " position, and be cycle to be tens minute by the oscillator that IC2 and peripheral components constituted this moment.Principle is the same with natural-wind-imitating, only is fan operation and stops to elongate at interval, and is sleeping so that the person drives sweat.And the air quantity of wind of sleeping this moment is still and is controlled by the speed governing unit, adjusts W1 and can well be fit to the effect of sleeping equally.

4, regularly: pull out " 1 " position with K1 from " 2 " position this moment, then the electricity on the C10 is by the be utmost point discharge of R38, W2 and T2, end by saturated becoming until T2, by back D15 output high level, T1 saturation conduction then, SCR turn-offs, and fan stops, and adjusting regularly, knob W2 can adjust timing.And this discharge-type time circuit finally can make fan stop, so the reliability height.

5。Infrared remote control start and stop: K1 puts " 2 " position, as long as press this moment this controller supporting infrared transmitter, after infrared receiving tube DH receives signal, handle through IC3, output removes to control the trigger that is made of T3, T4 through the T5 buffering, saturated or end to guarantee that the D14 output signal removes to control T1 on request, thus reach the effect of fan remote control start and stop.Here the mounting structure of adopter DH is the wide-angle formula, so that reliably accept the signal that transmitter sends under indoor multiple angles.

In sum, this Multifunction energy-saving controller for ceiling fan has following advantage:

Installing the simplest and easyly, only is to remove former speed regulator to connect its power line two ends and get final product work, and power consumption＜0.5W during operation does not produce humorous wave interference, has multiple functional, easy to use, cost performance advantages of higher.
