Abstract
The utility model relates to a novel reactance ceiling fan speed regulator. The existing speed regulator has the disadvantages that the rise of the rotary speed of the ceiling fan is slow, energy consumption increases, a motor is easy to generate heat, and the service life is influenced, when the speed regulator is started at a low block. When the speed regulator is started at a high block, though the speed regulator can be started quickly, the speed regulator is run at a medium-low block by people. So the procedure is complicated and time is wasted. The utility model adds a control circuit and an automatic time delay circuit which is composed of an integrated circuit 555 and a peripheral circuit. The foot 2 and the foot 6 of the integrated circuit 555 are connected and are respectively connected with a time delay resistor and a time delay capacitor. The foot 3 of the integrated circuit 555 is connected with a base electrode of a triode through a resistor. The emitter of the triode is connected with a relay. The other end of the relay is connected with the foot 1 of the integrated circuit 555.
Description
The utility model relates to a kind of hanging fan governor, and the reactance hanging fan governor of low-grade device for rapidly starting particularly is housed.
Ceiling fan is one of capital equipment of cooling in summer, and ceiling fan generally all is furnished with speed regulator, and during low-grade the startup, rotation speed of the fan rises slow, and motor easily generates heat, and influences useful life; Though can start fast when starting with top grade, rotating speed generally need manually go to required low grade after rising, and is cumbersome time-consuming, uses inconvenience.
But the purpose of this utility model provides a kind of automatic time delay control, and is both simple to operate, ceiling fan started fast, and do not influence the motor hanging fan governor in useful life.
The utility model is to add a delay circuit of being made up of integrated circuit, time delay resistance, electric capacity on the basis of former hanging fan governor; A control circuit of forming by triode and relay; The circuit composition that power supply is provided for delay circuit and control circuit.Delay circuit and control circuit are made up of ic 555 and peripheral circuit thereof, and 2 pin of ic 555 and 6 pin link to each other and link to each other with a delay capacitor with a time delay resistance respectively; 3 pin of ic 555 link to each other with the base stage of a triode through a resistance, and the emitter of triode links to each other with a relay, and the other end of relay links to each other with 1 pin of ic 555.Time delay resistance in the delay circuit can be a variable resistor, the Gear-shift switch interlock of it and speed regulator.Power circuit is a capacitor step-down rectifier circuit, and it is connected with fan electromotor with the reactor parallel connection of speed regulator again, uses the 220V alternating current jointly, decompression capacitor of input series connection of rectification circuit, an output voltage stabilizing didoe in parallel respectively and electric capacity.
The utility model is reasonable in design, and is simple to operate, and ceiling fan is started fast, and the use that does not influence motor is again received the order, and is a kind of comparatively ideal hanging fan governor.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the theory diagram of this speed regulator, is made up of original reactor and power circuit, delay circuit, control circuit, its essence is by switch element and controls the circuit that each tap of reactor is connected automatically.When speed regulator was extremely low-grade by the neutral gear plate, delay circuit control contact drew logical high speed circuit earlier, makes its high-speed starting, treated to become after rotation speed of the fan raises again and connected low grade, made its normal down running.
Fig. 2,3 is circuit theory diagrams, and its core is the delay circuit of forming with IC1 and R1C3, C4 etc.When Gear-shift switch SA1 by 0 plate washer to deep low gear 1 (or 2,3) when shelves, C3 begins charging, 2,6 ends of IC1 are in low-voltage, 3 end output HIGH voltages, the VT1 conducting, relay K 1 coil gets electric, and contact K1-1 breaks away from normally closed some b, connect normal battle of a, so fan electromotor is by 4 grades of high-speed startings of higher gears.After this (time length is determined by R1, C3 to pass through certain time-delay, and T=1.1R1C3), the C3 both end voltage rises to 2/3 of supply voltage, the 3 ends upset of IC1 is low-voltage, VT1 ends, the relay coil outage, normally closed some b of contact rebound, fan electromotor transfer to run well by 1 grade (or 2,3 grades).When SA1 pulled to 4 grades, the action of relay was with last identical, and ceiling fan is with 4 grades of high-speed startings, no speedup or deceleration effect.When SA1 pulled to 5 grades, relay was motionless, and ceiling fan is with 5 startups the most at a high speed.As seen, the low grade that village's device improves speed regulator starts effect, and does not influence the top grade startup of former speed regulator.
For the purpose of more accurate, when SA1 pulls different gears (both with the starting of different gear time), time-delay length can have nothing in common with each other, and can be arranged to resistance string or other resistance change element (as Fig. 3) with the SA1 interlock to R1 for this reason.Certainly can not be provided with yet.
Another distinctive feature of this speed regulator is the two ends (1 end and 5 ends) that the power supply of automatic control section is taken from reactor, connects with fan electromotor and uses the 220V alternating current, need not draw power line in addition.Form the simple voltage stabilizing circuit of capacitor step-down by C1, VD1～4, VD5, C2 etc., voltage is stabilized in about 6V.When SA1 pulled to 0 or 5 grade, this power supply was also disconnected, when pulling to 1,2,3 or 4 grade, was the subsequent conditioning circuit power supply.Because of the capacitance decompression voltage stabilizing circuit is strong to mains voltage variations adaptability, in the time of can guaranteeing that speed regulator starts with different gears, can both reliably working.Owing to the introducing of decompression capacitor, improved the power factor of circuit to a certain extent, use this speed regulator than using general speed regulator total current minimizing 10～20mA through actual measurement, have energy-saving effect.
