2. Description of the Related Art Conventionally, acidic water secondarily produced in an electrolyzer for producing alkaline ionized water for health promotion is
Although it is recommended for beauty and beauty use, and is used for private use, the amount produced is small, and even for general use, it was only an amount that can be used for beauty at best. In the field of medical care, in recent years, the problem of nosocomial infections caused by antibiotic-resistant bacteria is becoming more serious, and measures to prevent contact transmission from equipment other than airborne transmission are being investigated. It also relies on bath disinfection, etc., and some products for the purpose of sterilizing with acidic water by electrolysis are also introduced, but it is local and has not reached the stage of full-scale use. . In the beauty industry, hairdressers wash their hair and wash their face for a long time, and their hands are rough, but there is no effective countermeasure and it is a kind of occupational disease, which presents a very serious problem. Therefore, for both fields, fine powder of a drug that exhibits acidity when dissolved in hot water such as benzoic acid is hardened with a binder, or crystals such as acidic glass are filled into a container installed in the hot water passage and spouted water. Proposals have been made to mix.

[0003]

However, the acidity becomes too high at the beginning of the water discharge in which the solution accumulated in the container is discharged all at once. Value does not fall, or the amount of dissolution is too much,
It was consumed in a short time and none was put to practical use.

[0004]

Therefore, according to the present invention, a fine powder or the like is filled in a container without directly exposing the cold-cooled hot water to a chemical or the like that produces acidic water.
The purpose of the present invention is to provide a weak acid water desalinator that can make a desired weak acidity by guiding cold and warm water to make saturated acid water, and controlling and injecting a predetermined amount into running water for showers, etc. .

Another object of the present invention is to:
In order to control and adjust the pressure of the inflow water leading to the drug container and to control the amount of dissolution, the variable pressure reducing valve adjusts the difference in the pH of the raw water depending on the location and the desired pH depending on the application, and a thermostat type valve. It is intended to provide a weak acid water desalinator capable of maintaining a constant water temperature by providing a constant amount of dissolved amount even when the water temperature changes in summer and winter by keeping the water temperature constant.

Still another object of the present invention is to form a porous body such as a sintered body of graphite, carbon, or metal particles, which can control the inflow and outflow, and to form a porous body having variable porosity and porosity. The present invention provides a weak acid water freshener which can be freely controlled in and out by using it together with a pressure reducing valve of the formula.

Further, the present invention is to provide a weak acid water maker which can be made compact and simple, and can be used for the whole body at home or for a hair-washing shower to be used for beauty and facial treatment.

[0008]

Operation: That is, the weak acid water water purifier body has a pressure resistant structure made of stainless steel, aluminum, resin, etc., and the pressure resistant chemical container is made of resin, metal, etc. In a circular shape, forming a circular groove to form a pool of saturated water, and connecting it from the outer circumference to the inner side of a cylindrical porous body that is connected, depending on the variable pressure reducing valve and the desired porosity and pore diameter. It passes through a filter that controls the acidic saturated liquid to a certain amount, mixes it with tap hot and cold water in the neutral range flowing inside, makes it weakly acidic, and is used for hair washing, face washing, whole body shower, etc. Also, the gist is a configuration characterized in that weak acidic water, which is effective for preventing rough hands, can be continuously produced in large quantities.

The mechanism of a weak acid water maker according to the present invention will be described with reference to examples. The fresh water generator body 1 is made of stainless steel, and the bottom portion 2 is welded all around to form the bottom portion 2.
The elbow 3 and the center shaft 4 are welded to this.
The cartridge 6 having the center pipe 5 is loaded by using the center shaft 4 of the fresh water generator body 1 as a guide, the lid 7 is covered, the O-ring 8 and the washer 9 are successively placed, and the X-ring 11 is tightened by the knob 10 to secure the watertightness. It has a structure to have. In the embodiment, a fine powder of oxalic acid 14 is filled in the lower part of the cartridge 6 via an activated carbon layer 12 for removing residual chlorine and a PP mat 13 for partitioning to prevent turbulent flow. The upper and lower wire nets 15 flow out the oxalic acid 14,
Used as a set with the non-woven fabric 16 to prevent leakage, the resin lid 17 is loaded, and the lower part prevents the inflow of cold and warm water from overflowing.
A ring 18 is installed. The connecting portion 19 supports the transparent container 20 and constitutes the whole. The permeable container 20 has a pore size selected in advance depending on the place of use and the application.
A porous porous cylindrical graphite filter 21 having a porosity was built in, and a water inlet 22 leading to a shower and a water outlet was installed in the lower part, and a small lid 23 was installed in the upper part. A running water outlet 24 is provided, and in the embodiment, a shower hose 25 is connected to the running water outlet 24. The small X-ring 26 constitutes the watertightness of the filtration container.

[0010] In the medical field, for example, the washing and disinfecting in an operating room and the shower temperature in a beauty salon are about 35 to 38 ° C, although there are some differences in the summer and winter. In order to prevent the change in the water temperature, a highly accurate thermostat type mixed faucet is used, but the filling agent does not need to obtain an unnecessarily high solubility, but rather needs to reduce the amount of dissolution, so the water temperature in summer It is necessary to keep this temperature constant throughout the year. Further, if the pore diameter and rate are constant, the pressure of the inflow water can be easily changed by the variable pressure reducing valve 32, so that the amount of permeation can be changed. , Not shown, thermostatic valve,
It is better to set a variable pressure control valve.

The actual usage situation will be described. Switching valve 27
Is attached to the spout of the faucet, and cold / warm water is guided through the hose 28 and the universal inlet 29.
Residual chlorine is removed by the activated carbon layer 12 of the above, and it is brought into contact with the oxalic acid 14 and dissolved to form an aqueous solution.
Through the connecting portion 19 and into the permeation container 20. As the graphite filter 21 of the embodiment, which is loaded in the permeation container 20, a material having a pore diameter of 1.0 μm and a porosity of 23% was processed and manufactured to have a diameter of 30 mm, a thickness of 7.5 mm, and a length of 250 mm. . At the switching valve 27, 2.5 kg /
When cold and hot water is sent at a pressure of cm ^2, the pressure of hot water flowing to the shower is 2.0 kg / cm ² , and a differential pressure of 0.5 kg / cm ² is obtained, the pore diameter and porosity of the filter 21 are pressure loss. Therefore, in a filtration area of 235 cm 2 of the filter 21, a saturated solution of pH 1.0 is filtered at 9.1 cc / min at 20 ° C. When mixed with a warm water flow rate of pH 6.0 and 10 liters / minute, the desired pH is obtained.
It will be 5.0. Amount of saturated accumulated water inside the fresh water generator body 1,5
During 350 minutes when 00 cc is present, the pH value is constant, and if a customer, a doctor, a nurse, or one person uses it for 10 minutes, 35 people can be covered. The cartridge 6 can be filled with 5400 g of oxalic acid, and the dissolved amount at 20 ° C. is 9.5 g, so about 60 liters of saturated water can be secured, which is 600 people, 20 people / day or If you are a doctor or a nurse, you can use it for 30 days, that is, for one month or more. Table 2 shows the details.

When the pH value of cold / hot water is different, it can be adjusted by changing the pressure by the variable pressure reducing valve 32, or the melting temperature may be raised.

As a method of simplifying the equipment, the filtration container 20 is constituted by itself, and the oxalic acid 14 or its saturated liquid is stored between the filter 21 and the filtration container 20, and the pressurized water from the connecting portion 19 is passed through the variable pressure reducing valve 32. It is also possible to introduce. In FIG. 5, 31 is a shower 3 for cleaning.
3 is a thermostatic valve for pressurized water, and 34 is a thermostat valve for cleaning.

With respect to drugs that exhibit acidity, the following studies were conducted because they are harmless to the human body and are inexpensive. With respect to benzoic acid, the pH of the saturated aqueous solution at 20 ° C. was 5.82, and it was found that it cannot be used for beauty or disinfection cleaning. As for succinic acid, the pH of the saturated solution at 20 ° C is 4.2.
It was 3, and it was necessary to add 1.841 liters to mix with 10 liters of spouted water to obtain pH 5, and the stock solution and drug tanks became too large and were excluded. For fumaric acid, the saturated liquid pH at the same temperature is 3.88, but
It required 73.8 cc, and there was a problem that the tank capacity became considerably large. In the case of oxalic acid in the examples, the pH was
Is 1.02, which is only 9cc for 10 liters of water discharge.
It was good to mix with, it was also a food additive, it was cheap, and it was the best among those examined. Table 1 shows an example with oxalic acid.
