Description

The electronics fast water heater

The present invention relates to a kind of electronics fast water heater of electronic applications.

At present, gas heater is arranged on the market, electric heater, though they can both be for the user provides service function, also all have certain defective: involve great expense as gas heater, volume is big, and the electric heater current are little, and heating time is long.

The objective of the invention is in order to overcome above-mentioned drawback, for people provide a kind of cheap, volume is little, power consumptive province, the electronics fast water heater rapidly of heating.

The present invention discharges the dither electric current in the water, make cold water become hot water, and the ingenious combination of safety protective circuit realizes.

Below in conjunction with accompanying drawing electronics fast water heater of the present invention is specified.Fig. 1 is electronics fast water heater power supply reason figure of the present invention, and Fig. 2 is an electronics fast water heater complete machine front view of the present invention; Fig. 3 is an electronics fast water heater rearview.Among the figure:

D1～D7---diode R1～R6---resistance

C1～C6---electric capacity VT1～VT2---triode

T1～T2---transformer IC---integrated package

W---potentiometer K---mains switch

VS1---diac VS2---controllable silicon

Y---piezoelectric ceramic piece

Principle of the present invention and function technical characteristic are described in detail in detail below. One, mu balanced circuit;

Mu balanced circuit is by power transformer T1, diode D2～D7, electric capacity C3～C5, ic chip, potentiometer W form. Two, pulsation high-frequency circuit:

The pulsation high-frequency circuit is made up of resistance R 5～R6, capacitor C 6, triode VT1, VT2, transformer T2.Three, leakage protection circuit:

Leakage protection circuit is made up of capacitor C 1～C2, resistance R 1～R3, diode D1, piezoelectric ceramic piece Y, diac VS1, controllable silicon VS2.

Because the collector electrode of triode VT1 and transformer T2, L1 1 are joined; 3 of the emitter of triode VT2 and transformer T2, L1 join; The emitter of triode VT1 and the collector electrode of VT2 join; 6 of triode VT1 base stage and transformer T2, L2 join; 4 of triode VT2 base stage and transformer T2, L2 join.2 of its AB discharge in the water, implement its function with the combination that realizes this electronics fast water heater heater circuit.

In addition, in the voltage stabilizing circuit, ic chip 1 underfooting is connected with potentiometer W, and the resistance that changes potentiometer can change the output voltage of voltage stabilizing circuit, can change water temperature simultaneously.

The operation principle of electronics fast water heater of the present invention is described in detail in detail below.At first water heater is filled water.After energized, because transformer T1 transformation, 15 volts of alternating voltages of its secondary coil output are supplied with C3 filtering after diode D2～D5 rectification, obtain 3～12 volts of direct voltages again after the ic chip voltage stabilizing, offer the pulsation high-frequency circuit.

Because of triode VT1, VT2 in the pulsation high-frequency circuit are high-frequency triodes,, always there is a pipe guide logical among VT1, the VT2 again because the parameter of two pipes is not exclusively symmetrical.Under the positive feedback effect of coil L2, the very fast growth of the collector current of conduction pipe, until the magnetic flux of transformer core just stops when saturated, the another pipe ends always in the meantime, after the iron core magnetic flux is saturated, flux change goes to zero, thereby the electric current in each coil sharply reduces and end, then conducting and saturated of the pipe that originally ended.VT1, VT2 take turns conducting with end, form one and push away a push-pull oscillator of drawing, just produce the thousands of conspicuous and even tens thousand of conspicuous pulsating currents of high frequency at the L3 two ends, because of the coil turn of L3 is few, AB two point voltages are between 50～100 volts.

Because 2 of AB are discharged in the water, and the AB distance between two points is 5 millimeters.Because of 2 of AB have high frequency voltage, and its electric charge decomposes in water.So heat energy just took place in the water between the AB in 20 seconds.Because high-frequency current consumes very big in conductor.Therefore the high frequency voltage from 2: 300 millimeters places of AB consumes rapidly, and is reduced to zero.Because of the length of outlet pipe far surpasses 300 millimeters, so be perfectly safe.

In addition, leakage protection circuit is housed in water heater outlet also, is prevented the safety of getting an electric shock.Because C1, R1, VS1 form trigger impulse and form circuit, trigger impulse of every half period output makes controllable silicon VS2 conducting, water heater working.Because of an end M of resistance R 2 links to each other with water 1 in the outlet pipe.As water heater leaky being arranged is that water in the outlet pipe is charged, and electric current flows on the common port of capacitor C 1 and resistance R 1 through resistance R 2.Thereby destroyed trigger impulse, make the pulse of controllable silicon triggerless and end.Water heater dead electricity and not working.Electric leakage disappears.In this simultaneously, 220 volts of alternating currents inject piezoelectric ceramic piece Y through transformer T1 primary coil, D1, R3, and its promotion piezoelectric ceramic piece gives the alarm.

During use,, rotate " switch " knob K (being threaded to " opening ") as long as water heater is filled water.Crossing 20 seconds water promptly generates heat.Rotating " water temperature adjusting " knob W again can be by the temperature water outlet of regulating.

In sum, simplicity of design of the present invention and science, with low cost, volume is little, not only can fast cold water be heated, and can regulate the height of the size and the water temperature of current easily, be a kind of electronics fast water heater that is widely used in family, barber shop, unit, factory etc.
