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pollution of the water environment is deteriorating day by day, the treatment process of the existing waterworks is outdated, and the quality of the factory water has been difficult to meet the standard (especially in the case of sudden drinking water sanitation incidents);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

Embodiment 2

[0062] The commercial water dispenser of this embodiment is basically the same as that of Embodiment 1, and the difference from Embodiment 1 is that the distance δ between the water-permeable diaphragm 5 and the negative electrode 2 in this embodiment is 0 mm, that is, the water-permeable diaphragm 5 is closely attached to the cathode electrode 2 at the same time. On the cathode electrode 2 and the anode electrode 3. The water-permeable diaphragm 5 still adopts a PVDF ultrafiltration membrane (polyvinylidene fluoride membrane) with an average hydrophobic pore diameter of 0.03 microns, and a thickness of 0.1 mm.

[0063] The water electrolysis experiment was carried out with the commercial water machine of this embodiment and the first embodiment, the source water was city tap water, ORP=+320mv, pH=7.1, TDS=160mg / L, electrolyzed for 20 minutes, other experimental conditions were the same as in the first embodiment The same, the results of the two experiments are as follows in T...

Embodiment 3

[0071] The commercial water machine of the present embodiment is basically the same as the first embodiment, as image 3 As shown, the changes different from the first embodiment are: 1) a first through hole 8 is opened on the negative electrode 2, and the diameter of the through hole is 1 mm; 2) the water-permeable diaphragm 5 covers part of the surface of the positive electrode 3 (the positive electrode 3) the distance δ between the water-permeable diaphragm 5 and the cathode 2 is 2 mm.

[0072] The commercial water machine of this embodiment is subjected to water electrolysis experiments. In this embodiment, 24 first through holes with a diameter of φ1mm are evenly distributed on the negative electrode, and the electrolysis time is 20 minutes. Other experimental conditions and detection methods are the same as in Embodiment 1. , the experimental results are shown in Table 3:

Abstract

The invention relates to a business water machine which comprises a host and a drinking water terminal, wherein the host comprises a water purifier and a water storage container communicated with the water purifier; the drinking water terminal is provided with a water tank; the water tank is communicated with the water storage container; a first sterilization device is arranged in the water storage container; a second sterilization device is arranged in the water tank; each of the first sterilization device and the second sterilization device comprises at least one pair of negative and positive electrodes and an electrolysis power supply for supplying power to the negative and positive electrodes; a water-permeable membrane is arranged between the negative and positive electrodes in pairs and covers the positive electrode; the distance delta between the water-permeable membrane and the negative electrode is not less than 0mm and not more than 10mm. The water machine is capable of preparing active hydrogen-rich drinking water with 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...
