Description

BACKGROUND OF THE INVENTION

The present invention relates to an electrolysis device, more specifically, relates to an electrolysis device for preparation of hypochlorous water, wherein the mixture of tap water and salt is electrolyzed to produce chlorine which is mixed with water to generate hypochlorous water.

The principle for generating hypochlorous water is: water (H2O) added with salt (NaCl) is electrolyzed through the electrolysis device. Chlorine (Cl2) is generated from the salt (NaCl) at the anode, which is then reacted with water (H2O) to generate hypochlorous acid (HOCl) and hydrochloric acid (HCL). The chemical reaction is 2 NaCl+4 H2O+Electricity=2 HOCl+2 H2+2 NaOH. The conventional electrolysis devices for the preparation of hypochlorous water have the following problems: 1) the use of the electrolytic cell with an ion membrane to generate hypochlorous water needs expensive ion membranes; 2) two separate tanks are required for containing hydrochloric acid and tap water which is spacious. It is hence necessary to improve the conventional electrolysis devices for preparation of hypochlorous water.

BRIEF SUMMARY OF THE INVENTION

Given the disadvantages of the conventional electrolysis devices for preparation of hypochlorous water having complex structure due to the ion membrane and spacious structure of two separate tanks, the present invention is intended to provide an electrolysis device for preparation of hypochlorous water which has simple and compact structure to lessen its overall size.

In the present invention, an electrolysis device for preparation of hypochlorous water is provided, comprising a cathodic electrolytic sheet, an anodic electrolytic sheet, an insulating sheet, two electric conductors and an electric controller affixed in an electrolytic cell.

The principle for generating hypochlorous water of the present invention is: water (H2O) added with salt (NaCl) is electrolyzed through the electrolysis device. The cathodic electrolytic sheet, anodic electrolytic sheet are connected to electric controller via the two electric conductors.

Chlorine (Cl2) is generated from the salt (NaCl) at the anodic electrolytic sheet, which is then reacted with water (H2O) to generate hypochlorous acid (HOCl) and hydrochloric acid (HCL). The chemical reaction is 2 NaCl+4 H2O+Electricity=2 HOCl+2 H2+2 NaOH. The hypochlorous water prepared by the electrolysis device has sterilization and environmental protection effects, and can be used as food additives, or used to produce disinfectant. The main improvement of this invention lies in how to reduce the size of the electrolysis device and enhance the efficiency for preparation of hypochlorous water.
