Description

Double-function timing, stepless speed-regulating electric fan controller

This model utility belongs to the control field of household electric appliance, and the electric fan that is mainly used in various models, all size carries out switch, stepless speed regulation, the timing of regularly closing or circulate, natural-wind-imitating, controls such as working state demonstration.

The Electric fan controller that uses adopts mechanical timer mostly at present, and machinery is transferred sense step change etc.Sort controller, function is few; Series inductance decompression speed power consumption is big; Mechanical timer and mechanical speed change switch are all for having the contact, having wearing and tearing to adjust the life-span weak point.Recently, a kind of electric fan " Computerized controller " occurred, its principle is four single-chip microcomputers that adopted CMOSZ technology to make, and comes power, timing and the various function of controlled wind speed to show with special written program.The deficiency of these electric fans " Computerized controller " is: adopted stepping regularly, and the stepping speed change, the regulated at will during use is bad, complicated operation, cost height.

The utility model is intended to overcome above-mentioned shortcoming, increases the function of electric fan, improves the regulated at will when using, and also makes every effort to simple to operate simultaneously, reduces cost.

Design of the present utility model is: produce required various time-base signals with three square-wave generator circuit.First square-wave generator EDM Generator of Adjustable Duty Ratio produces cycle 0.06-0.14 speed-regulating signal of (power supply 50Hz) between second.Second square-wave generator dutycycle 1:1 produces the natural-wind-imitating signal of 15-30 between second.The 3rd square-wave generator removes the no steady state that utilizes EDM Generator of Adjustable Duty Ratio and produces circulation timing signal between cycle 10-40 minute, the adjustable timeing closing signal that can also utilize monostability to produce 0-180 minute.The signal of these three square-wave generators, by an OR-NOT circuit, form one " with " signal goes to control the break-make of electronic switch.The electric fan of electronic switch control will blow out various wind according to user's regulated at will like this.

Fig. 1 is a circuit diagram of the present utility model.

Fig. 2, Fig. 3 are the external form schematic representation of the utility model controller.

Be embodiment of the present utility model below:

In Fig. 1, ［ 1 ］ is electric fan, and the 220V civil power is through DC power supply circuit ［ 2 ］, after rectification, filtering, the voltage stabilizing, give stepless speed regulation circuit ［ 3 ］, difunctional time circuit ［ 4 ］, natural-wind-imitating circuit ［ 5 ］, OR-NOT circuit ［ 6 ］ and working state and rotating speed display circuit ［ 8 ］ power supply.Stepless speed regulation circuit ［ 3 ］, difunctional time circuit ［ 4 ］, natural-wind-imitating circuit ［ 5 ］ all is the square-wave generator circuit.Different is: stepless speed regulation circuit ［ 3 ］, and the cycle is 0.1 second (power supply 50Hz), dutycycle 20:100-100:1 is adjustable, in order to produce intermittently stepless speed regulation signal of duty formula.Difunctional time circuit ［ 4 ］ is convertible into monostable circuit by K switch; When time circuit K disconnected, the generation cycle was 30 minutes, the circulation timing signal that dutycycle 1:100-100:1 is adjustable; When connecting, K produces 0-180 minute adjustable timeing closing signal.Natural-wind-imitating circuit ［ 5 ］, cycle is 20 seconds, dutycycle 1:1, produce the natural-wind-imitating signal, OR-NOT circuit ［ 6 ］ is with the stepless speed regulation signal, difunctional timing signal, the natural-wind-imitating signal, through logical conversion, form one new " with " signal removes to control the Push And Release of electronic switch ［ 7 ］.Electric fan ［ 1 ］ will blow out various wind according to user's regulated at will like this.Working state and rotating speed display circuit ［ 8 ］ are subjected to difunctional time circuit ［ 4 ］, natural-wind-imitating circuit ［ 5 ］ and OR-NOT circuit ［ 6 ］ produce " with " SC sigmal control, with the Light-Emitting Diode (LED) Displaying timer, imitate wind, turn round, stop, rotating speed etc.

As Fig. 2, shown in Figure 3, each toponym and the function of controller:

9, stepless speed regulation knob, the power switch (push-and-pull potentiometer) of holding concurrently: pull out power connection, the electric fan entry into service.Knob clockwise direction rotation wind speed is accelerated, otherwise slows down.

10, timing adjusting knob, the timing mode throw over switch (push-and-pull potentiometer) of holding concurrently: when pulling out the timeing closing working method, the rotation of knob clockwise direction, the timing lengthening, on the contrary shorten.Timing 0-180 minute adjustable.Be circulation timing working mode when pushing, cycle period is about 30 minutes, and knob turns clockwise, and extend running time, and stop time shortens.Otherwise counterclockwise.In the circulation timing cycle, can adjust in 0-30 minute running time.

11, natural-wind-imitating switch.

12, time switch.

13, natural-wind-imitating shows luminotron tube.

14, turn round, stop, rotating speed shows luminotron tube.

15, regularly show luminotron tube.

16, label plate.

17, shell.

Double-function timing, stepless speed-regulating electric fan controller can support the use for various electric fans, also can form independently product, connect the common electrical fan that enters family, make it increase function and improve the grade. It is many to have function, little power consumption, and the life-span is long, and cost is low, and is simple to operate, uses the characteristics such as random. Summer controlled electric fan by this controller, and can control winter to electric mattress.
