Business water machine

Abstract

Provided is a commercial water machine. The water machine comprises a main machine (1) and a drinking water terminal (9). The main machine comprises a water purifier (1-1) and a water storage container (1-2) which is in communication with the water purifier (1-1). The drinking water terminal (9) is provided with a water tank (9-1). The water tank (9-1) is in communication with the water storage container (1-2). A first sterilization device is provided in the water storage container (1-2). A second sterilization device is provided in the water tank (9-1). Both the first sterilization device and the second sterilization device comprise at least one pair of negative electrode (2) and positive electrode (3) and an electrolytic power supply (4) used for supplying electricity for the negative electrode (2) and positive electrode (3). A water permeable separation film (5) is provided between the pair of negative electrode (2) and positive electrode (3). The water permeable separation film (5) is covered on the positive electrode (3). The spacing δ between the water permeable separation film (5) and the negative electrode (2) is in a range of 0 ≤ δ ≤ 10 millimetres. The water machine can prepare a potable water which is rich in active hydrogen and has a low redox potential.

Description

technical field [0001] The invention relates to a commercial water machine, which belongs to the technical field of water electrolysis equipment. Background technique [0002] Water is the source of life. With the progress of society and the aggravation of environmental pollution, people have higher and higher demands on the quality of daily water (including residential water, medical water, beauty water, food production and other industrial water, etc.), especially domestic water quality. Diverse needs. [0003] The daily water provided by the municipal government, even if the factory water quality and safety indicators of the waterworks basically meet the standards, the "tap water" delivered to the public water terminal has become a kind of (special) slightly polluted water due to the following reasons: [0004] 1) The pollution of the water environment is deteriorating day by day, the treatment process of the existing waterworks is outdated, and the quality of the facto...

AI Technical Summary

Problems solved by technology

[0004] 1) The pollution of the water environment is deteriorating day by day, the treatment process of the existing waterworks is outdated, and the quality of the factory water has been difficult to meet the standard (especially in the case of sudden drinking water sanitation incidents);

[0005] 2) Secondary pollution caused by the water delivery pipe network system;

[0006] 3) Residual chlorine in water interacts with residual organic matter, which may generate new harmful substances that are not in source water (such as strong carcinogen chloroform, etc.)

However, the common problems existing in the existing electrolysis or electric field sterilization, ozone and other sterilization methods are that the oxidation factor produced in water is often non-selective, the intensity is difficult to control, and it is easy to produce toxic and side effects (for example, improper ozone disinfection can easily generate strong carcinogens - Bromate)
