Description

The high-frequency electrolysis water making machine

Technical field

The utility model relates to a kind of water making machine capable of direct drinking, particularly a kind of high-frequency electrolysis water making machine.

Background technology

Existing electrolysis water machine technology is to adopt linear power supply and low frequency (100Hz is following) electrolysis tech substantially, and frequency is constant, can't adapt to the complicated water quality situation that different zones pH value, specific conductivity, ORP value, hardness etc. differ greatly, more can't provide the electrolysis degree of depth of wide region to adjust the requirement of satisfying high-quality system water.

Summary of the invention

The purpose of this utility model is to provide the water quality environment that can adapt to various complexity, the high-frequency electrolysis water making machine that can control the electrolysis degree of depth ideally.

The purpose of this utility model is achieved in that it has the barrel of adding, electrolyzer, water discharge valve assembly, transformer and cleaner, it is characterized in that: it also has hf switching power supply, this circuit is: by micro-chip control Novel MOS FET switching tube M3, M4, control driving transformer T2, and then driving switch pipe M1, M2, utilize the advantage design semibridge system driving circuit control convertor transformer T1 that its switching speed is fast, loss is little, by adjusting pulse-repetition, dutycycle realization Faradaic current intensity control.The interface of micro-chip is connected with power source circuit by isolation method, forms half control bridge circuit and water discharge valve assembly by micro-chip control by M5, M6 and D12-D15.Realize the transient state conversion sense of current, thereby prevent pole plate fouling and polarization, effectively improve electrolysis effectiveness.

The utility model is compared with the prior art scheme, and its advantage shows:

At first, under the high-frequency electric field effect, the electrolyzer two ends form the dither electric field of a particular frequencies, and the pulsation power supply provides abundant harmonic current components for electrolyzer.The harmonic excitation of this transient state has formed the higher frequency electromagnetic field of a frequency band broad in water, water is during by the higher frequency electromagnetic field, its original inertia physical structure will change, water molecules is activated, and produces the ionic polarization phenomenon, for changing water clusters huge usefulness is arranged;

Secondly, adopt high-frequency electrolysis technology moment electric current by electrode up to tens amperes, make in the water ion motion after the electrolysis rapider than the low frequency electrolysis, ionic forms speed much larger than in conjunction with speed.Simultaneously, the potential gradient on high-frequency impulse condition lower electrode surface is dynamic, and its Potential distribution is more than uniformly many under the low frequency condition, thereby electrolysis effectiveness is also just better;

Once more, because collection (becoming) the skin effect characteristic of electric current, the high-frequency impulse electrolysis makes electrode surface have very high current density, makes the electrolytic reaction in the water more abundant;

The electrolysis of constant current mode is adopted in the low frequency electrolysis, this is very big to the ion film lifetime effects in the electrolyzer, and adopt the high-frequency impulse mode to obtain dynamic current by adjusting pulse duty factor, rather than single constant electric current, by ionic membrane self-recovery characteristic, greatly reduce irrecoverable property infringement to ionic membrane.

When dither electric field peak-to-peak, displacement has taken place from its equilibrium theory of tide in negative ions rapidly, and during peak valley, electrostatic attraction descends, and pole plate, film surface salt ion come off, and reduce because of movement velocity reduces effective collision simultaneously, has improved to prevent the fouling effect;

High-frequency impulse promptly constantly repeats the high-frequency pulse electrolytic process of " power supply-outage-power supply " in addition, conduction time is less than the electrolysis treatment total reaction time, owing to apply pulse signal, reaction on the electrode off and on, help diffusion, reduce concentration polarization, thereby the reduction power consumption is improved electrolytic efficiency significantly.

This equipment has also adopted advanced micro-chip control simultaneously, possess controlled frequency conversion rate, time-dependent current, conversion electrolysis direction and automatic anti-cleaning function, not only can further promote electrolysis strength, improve electrolyzer work-ing life, possess also that to dazzle dynamically that light shows, direct election formula operating panel has the man-machine communication interface good, simple to operation, characteristics such as intelligent height.
