Abstract
The utility model discloses a multifunctional speed regulating device for a ceiling fan which integrates a wall fusing lamp, a ceiling fan speed regulator, and a temperature regulating socket. The appearance of the multifunctional speed regulating device for a ceiling fan is like a wall lamp. The multifunctional speed regulating device for a ceiling fan not only can regulate speed for a ceiling fan, but also can regulate temperature, and speed regulation and temperature regulation share the same output end. The multifunctional speed regulating device for a ceiling fan uses a self-excitation multi-harmonic oscillator and a bidirectional controlled silicon to carry out intermittent speed regulation for the ceiling fan. The multifunctional speed regulating device for a ceiling fan has the function of simulating natural wind, which causes the wind sending of the ceiling fan mellow, people feel comfortable. A simple low speed low voltage starting circuit is especially designed by the multifunctional speed regulating device for a ceiling fan in order to solve the problem that the ceiling fan is difficult to be started in low speed and low voltage.
Description
The utility model is to utilize electronic technology to carry out speed governing to exchanging ceiling fan, and has wall lamp, natural wind simulating and temperature adjustment function.
Existing interchange regulator of fan adopts inductance tap speed regulating method.It is the different pressure drops that utilize supply voltage to produce in the different tap of inductance, thereby changes the terminal voltage of ceiling fan, and reaches the purpose of speed governing.The hanging fan governor of selling on the market is exactly this form now.This method efficient is poor, and power factor is low, and low and middle-grade power consumptions are big, and especially reactive power consumption is bigger, has increased the electrical network burden.The existing in addition method with diac and bidirectional triode thyristor speed governing is by changing the angle of flow of bidirectional triode thyristor, realizing speed governing.But this method exists voltage waveform distortion, produces radio frequency interference, influences household electric appliance proper functioning such as radio receiver, pollutes power-supply system when serious, so can not become commodity always.Occurred the silicon control zero-cross trigger circuit in recent years again, sort circuit is complicated, is used to exchange the ceiling fan speed governing, and low speed low voltage startability is undesirable.
The purpose of this utility model provides a kind of multifunctional hanging fan arrangements for speed regulation that are designed to one by wall lamp, hanging fan governor and temperature regulating socket, it is to utilize astatic multivibrator and bidirectional triode thyristor that ceiling fan is carried out the speed governing at intermittence, and can overcome the problem that ceiling fan low speed low voltage starts difficulty effectively.
The utility model is realized by following structure: inertia is big when utilizing the interchange ceiling fan to start, and the big characteristics of running back inertia trigger bidirectional triode thyristor with astatic multivibrator ceiling fan is carried out the speed governing at intermittence.Start difficulty in order to solve ceiling fan low speed low voltage, specialized designs simple and easy low speed low voltage start circuit.This device appearance resembles a wall lamp, both can give the ceiling fan speed governing, can give the electric mattress temperature adjustment again, and the shared same output terminal of speed and temp regulating.Wall lamp can be incandescent lamp, fluorescent lamp or color lamp.
The utility model is the multifunctional hanging fan arrangements for speed regulation that wall lamp, hanging fan governor and temperature regulating socket are designed to one, and is practical.Hanging fan governor is to utilize astatic multivibrator to trigger bidirectional triode thyristor ceiling fan is carried out the speed governing at intermittence, and has the natural wind simulating function, makes the ceiling fan air-supply soft, feels comfortable.Removed big, the inefficient shortcoming of inductance speed regulator power consumption, saved electric energy, the low speed low voltage start circuit has guaranteed the reliable startup of ceiling fan when the low speed low voltage.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the circuit theory diagrams according to the multifunctional hanging fan arrangements for speed regulation that the utility model proposes.
Fig. 2 is according to the multifunctional hanging fan arrangements for speed regulation schematic appearance that the utility model proposes.
Describe the utility model circuit working process in detail below in conjunction with Fig. 1.
The 220V Ac is through transformer B1 transformation, and diode D1-D4 bridge rectifier after the C1 filtering, provides galvanic current to press VCC to astatic multivibrator.Astatic multivibrator is made up of R1, R2, R3, D5, D6, W1, C2 and time base circuit 555.R1, R2, D5, W1 and C2 form charge circuit, and C2, W1, D6, R3 form discharge loop.8 pin and 4 pin of time base circuit 555 connect positive source, and 1 pin connects power cathode.3 pin are output terminal, are connected on bidirectional triode thyristor SCR control by current-limiting resistance R4 and extremely go up.5 pin connect a capacitor C 4 anti-tampering usefulness, and 7 pin are discharge end, and 6 pin are the threshold value input end, and 2 pin are for triggering input end.
The working principle of this circuit is such: when circuit has just been started working, power supply gives capacitor C 2 chargings by R1, R2, D5, W1, because the voltage on the C2 can not suddenly change, the voltage on the C2 is less than 1/3VCC, at this moment 3 pin output high level, bidirectional triode thyristor SCR conducting.C2 constantly charges, and when the voltage on the C2 surpassed 2/3VCC, capacitor C 2 was discharged to 7 pin of time base circuit 555 by W1, D6, R3, the circuit upset, and 3 pin output low levels, bidirectional triode thyristor SCR ends.When the C2 terminal voltage discharges into when being less than 1/3VCC, circuit overturns again, 3 pin output high level, bidirectional triode thyristor SCR conducting again.Adjusting W1 can change the time constant that discharges and recharges of circuit, has also just changed dutycycle, thereby has realized the intermittence speed governing of ceiling fan from full speed to low speed, and has the natural wind simulating function.
Ceiling fan starts relatively difficulty in the low speed low voltage, the low speed low voltage start circuit of being made up of D7, C3, K1 is attempted by the C2 positive pole, and the positive pole of C3 was connected on the normal battle of K1, as closed K1, power supply not only charges to C2 by R1, R2, D5, W1, but also charges to C3 by D7, increased the duration of charge, make 3 pin output high level time elongated, bidirectional triode thyristor SCR ON time is also elongated, has guaranteed the reliable startup of ceiling fan under the low speed low voltage condition.First charge cycle, just ceiling fan is work like this starting time, when the C2 terminal voltage reached 2/3VCC circuit rollover states, C2 began discharge, but because the effect of D7, C3 can not discharge, and can not influence the circuit time constant of work later on yet.Have only when the K1 deenergization, when ceiling fan stops,, make C3 drain electric charge because become normally closed some the normal battle of K1, ready for start ceiling fan next time.
CZ is the speed and temp regulating socket, can connect ceiling fan, also can connect electric mattress.K1 is the speed and temp regulating power switch, and K2 is the wall lamp switch, and D is an incandescent lamp, and L is a fluorescent lamp ballast, and YD is a H type fluorescent lamp.With reference to Fig. 2: this device comprises wall lamp (1), hanging fan governor (2) and temperature regulating socket (3).
