Description

Multi-functional electronic timing regulator

The utility model relates to a kind of electronic controller, particularly a kind of voltage regulator that can be regularly.

At present, the commercially available general power of alternating electron regulator is less, and common electronic pressure controller power is mostly less than 1KW.But commercially available many appliance powers are all between 1-2.5KW, so the contradiction that existing electronic voltage regulator can not satisfy existing electrical equipment range of regulation occurred.For this reason, disclose a kind of energy-saving electric heating adjuster among the Chinese patent CN2066211U, this adjuster is by DC power supply, and control circuit and bidirectional triode thyristor are formed.This adjuster adopts by transformer, the current rectifying and wave filtering circuit that rectifier diode and filter capacitor are formed, and output dc voltage is for IC work.Form a low-frequency square-wave oscillator by electric capacity, potentiometer, resistance, diode, IC, the duty ratio of its input square wave can be determined by potentiometer.Though this adjuster has realized that adjustable range is wide, but the purpose of regulating from the 0-2KW continuous stepless, but, use element many because the circuit of this adjuster is complicated, increased the production cost of adjuster.

The purpose of this utility model be to provide a kind of simple, reliable, range of regulation is big, the multifunction electronic timing governor that can be used for various loads and can regularly cut off the power supply.

The purpose of this utility model realizes by following proposal: establish major loop and control loop in the housing of adjuster.Control loop comprises bidirectional triode thyristor, RC charging circuit, bidirectional trigger diode, switch element, and bidirectional triode thyristor one termination is gone into the input of power supply, and the other end is by switch, RC charging circuit, the diac access control utmost point.

Above-mentioned RC charging circuit comprises R2, W and C1.

Above-mentioned switch is a timer.

Above-mentioned box body one side is established input plug, and opposite side is established timer adjusting knob, pressure regulation sliding handle and accessory power outlet.

The conducting trigger voltage of bidirectional triode thyristor is provided by the charging voltage of C1 in the adjuster circuit, and the charging speed of C1 has determined the size of the bidirectional triode thyristor angle of flow.Regulator potentiometer then can change the speed of C1 charging, thereby changes the angle of flow of bidirectional triode thyristor.Bidirectional trigger diode control trigger voltage.When W transfers greatly, the C1 charging is slow, and the angle of flow of D1 is little, and output voltage is low.When W turns down, C1 then charges soon, the angle of flow of D1 is big, the output voltage height.Inductance L and capacitor C 2 can suppress the high order harmonic component that controllable silicon causes.Light-emitting diode D3 and resistance R 1 are formed indicating circuit.

The utility model can be widely used in various loads, as aspects such as electric cooker, household electrical appliance, laboratory paraphernalias.The range of regulation of adjuster is between 40-210V, and power regulating range is between 40-2500W.Timing range is adjustable continuously at 0-120 minute.Because timer can regularly cut off the power supply at the appointed time, not only provides convenience to the user, has saved the time, and has reduced many troubles.The pressure regulation of adjuster is stepless, convenient, be used for the electric cooker soup that can prevent to be burned, overflow.The volume of adjuster is small and exquisite, can directly be inserted in the supply socket, and the attaching plug of electrical appliance can directly be inserted on the accessory power outlet of adjuster.Make electrical equipment avoid many unnecessary excess loads, thus the useful life of electrical equipment not only can be prolonged, and can save electric energy.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a front view of the present utility model;

Fig. 2 is an end view of the present utility model;

Fig. 3 is a circuit diagram of the present utility model.

As shown in Figure 1, governor body (1) front is provided with indicator light (2), timer adjusting knob (3), pressure regulation sliding handle (4), accessory power outlet (5).

As shown in Figure 2, the back side of housing (1) is provided with input plug (6).

As shown in Figure 3, control loop comprises bidirectional triode thyristor D1, RC charging circuit, bidirectional trigger diode D2, timer.Bidirectional triode thyristor D1 one termination is gone into the input of power supply; the other end comprises R2, W and C1 by the control utmost point, the RC charging circuit that timer, RC charging circuit, diac D2 insert D1, and inductance L and capacitor C 2 are formed the protection loop and be used for suppressing the high order harmonic component that controllable silicon causes.Light-emitting diode D3 and resistance R 1 are formed indicating circuit.
