Method and device for water production by electrolysis with compensation for water velocity

Abstract

The invention relates to a method and a device for water production by electrolysis with compensation for water velocity, and is intended to provide people with fine drinking water and cosmetic washing water. The method comprises the following steps: detecting the water velocity of water entering an electrolytic cell; then, carrying out the comparison operation with the set value, and carrying out the pulse width modulation (PWM) according to the results of the comparison operation; and adjusting the electrolytic current of the electrolytic cell at any time according to the generated PWM signals to cause the electrolytic current thereof to be adjusted along with the change in the water velocity. Therefore, the invention can solve the technical problem that the pH value of the electrolyzed water varies with the water velocity in the prior art of water production, technically, the pH value remains almost constant within a certain range; meanwhile, the electrodes are automatically switched from one another each time the device is used by a user, scale can be shifted towards an opposite direction and washed off along with the water flow when the device is used next time, thereby achieving the purpose of automatic cleaning; and the invention has the advantage of wide application.

Description

technical field [0001] The invention relates to a method and device for electrolytic water production, in particular to an electrolytic water production method and device with a compensation function, belonging to the field of electrolytic water production. Background technique [0002] As we all know, the water source of the electrolytic water generator is provided by standard tap water or a local self-run water plant. The raw water is electrolyzed, thereby continuously changing the DC voltage of the power supply to control the pH value of the electrolyzed water. [0003] However, due to the differences in water pressure and water supply pipe diameters on different floors, even for the same user at different times in the same day, that is, the water pressure and water flow rate during the period of less water consumption and the peak period of water consumption vary greatly, resulting in electrolysis of water. The PH value changes greatly, so relying on the original tradit...

[0003] However, due to the differences in water pressure and water supply pipe diameters on different floors, even for the same user at different times in the same day, that is, the water pressure and water flow rate during the period of less water consumption and the peak period of water consumption vary greatly, resulting in electrolysis of water. The PH value changes greatly, so relying on the original traditional thinking to make electrolytic water generators has great limitations in actual use
