本発明は、風呂水やプール用水などの水を浄化する業務

気泡発生装置付泡風呂は、一般の風呂に比較して菌の繁

生し、不衛生きわまる状況である。Conventional technology For example, in the case of a home bath, conventional home baths simply boil water, and each time you take a bath, dirt, scales float, and bacteria grow. In particular, recently developed bubble baths with bubble generators for home use have more bacterial growth and floating scale than regular baths, resulting in unpleasant odors and slime, making them extremely unsanitary. .

なくなると菌やカビが繁殖しメンテナンスに問題があり
家庭用には不向きであった。There are methods that use chlorine, ultraviolet rays, etc., but if you use these methods for home baths, you can sterilize bath water, but
Water scale etc. cannot be removed. As a means of removing this scale, filtration with a filter is often used, but even if you simply filter the bath water with a filter, the bacteria attached to the scale will grow on a part of the purification filter, creating a nest of bacteria. This caused the problem that when fresh water entered, the water would be contaminated by the bacteria that had grown. Therefore, it is possible to purify bath water by combining the above-mentioned sterilization technology and filtration technology using a filter, but ozone is harmful to the human body and its use in a bath environment must be avoided. Chlorine has a long-lasting effect and can sterilize the bath water while chlorine is being replenished, and there is no growth of bacteria on some parts of the filter, but when chlorine is no longer supplied, bacteria and mold can grow. It was not suitable for home use due to maintenance problems.
一方、紫外線ランプはメンテナンスフリーで、いつまで

あった。On the other hand, ultraviolet lamps are maintenance-free and can be sterilized indefinitely, making them suitable for sterilizing household bath water. However, the conventional filters used in conjunction with them quickly become clogged with scale, so they must be replaced constantly. Since it is a hassle to use a filter, there was a need for a maintenance-free filter that would not get clogged with scale.
本発明は上記従来技術の課題を解決するものであり、炉
材の目づまり解消と水の殺菌をはかることを目的とする
。The present invention solves the problems of the prior art described above, and aims to eliminate clogging of furnace materials and sterilize water.

As a result, clean water free from organic contamination and bacterial contamination can be obtained without maintenance.

戻る。Embodiment FIG. 1 shows an embodiment in which the water sterilization and purification device of the present invention is applied to a bubble bath. The water sterilization and purification device 1 was placed in the circulation channels 3a and 3b of the bath 2. The water in the bath 2 passes through an inlet 4 and a water flow path (outward path) 3a, and is removed by a pump 6 using a filter material e carrying a photocatalyst to remove dirt such as scale. Next, the water from which scale has been removed is sterilized by an ultraviolet lamp 7 and returns to the bath 2 from an outlet 8 via a water flow path (return path) sb.

。This means that if you place an ultraviolet lamp in the front stream, the ultraviolet light will
Because the sterilizing effect is temporary and does not last, there is no sterilizing effect on the downstream filter media, so if bacteria grows in the downstream filter media, there is a risk that the bacteria will flow into the bath. It is.

ないようになっている。Therefore, in the present invention, the ultraviolet lamp 7 is disposed downstream of the internal space of the upstream purifying filter material 6, and the purifying filter material 6 is always
In addition to preventing the growth of bacteria by irradiating the filter with water, the photocatalyst supported on the filter material oxidizes and decomposes the scale attached to the filter material. Therefore, the purifying filter material 6 carrying the photocatalyst and the ultraviolet lamp 7 that activates the photocatalyst and also sterilizes were stored in the same container. Furthermore, this ultraviolet lamp is housed in the internal space of the water shield 11 so as not to come into contact with water.

ことができる。The ultraviolet lamp 7 is a waterproof type with a center wavelength of 253.7 μm, and is made of quartz or ultraviolet transmitting glass (low F e 20 s silicate glass, borosilicate glass, low alkali, phosphoric acid glass) that transmits this wavelength well. The irradiation part is made of salt glass). The ultraviolet lamp 7 is provided with an electric lead wire 16 for transmitting power.
Possible configurations include one in which the ultraviolet lamp is led out from a hole 17a made in the center of the lower and upper lids 17 fixed in the lamp, and one in which the ultraviolet light is led out from one end of the ultraviolet lamp 7. Water blocker 1
The material 1 is one or more selected from the group of quartz, fluororesin, and ultraviolet-transmitting glass, and preferably quartz or quartz coated with fluororesin.Quartz or fluororesin is particularly excellent in transmitting ultraviolet rays. Because of this, sterilization and photocatalyst can work effectively. In addition, the water sterilization purification unit arranges a filter material 6 carrying a photocatalyst in a metal container 12, and arranges a water barrier 11 in the internal space thereof.
The water was allowed to move 360 degrees around the filter medium 6 and the blocking body 11. Therefore, the light from the ultraviolet lamp 7 is
It can be used 360 degrees to efficiently sterilize water and act as a photocatalyst.

。The purifying filter material 6 carrying a photocatalyst is made by carrying TlO2 as a photocatalyst on polypropylene fibers. The optimal pore diameter of this purifying filter material is 1 to 100 μm, preferably 2 to 20 μm. This is because this pore size best allows scale to adhere and be decomposed by the photocatalyst. On the other hand, the higher the porosity, the better the water flow, but it was set to 20 to 60% due to the material composition. Further, the purification filter material 6 may be made of a ceramic porous material or the like.

Bacterial growth was observed at 2×106 cells/me. Furthermore, Table 1 shows the results of evaluating the amount of decomposition of the attached scale by varying the type and amount of the photocatalyst supported on the furnace material. From Table 1, TiO□ acts as a photocatalyst to reduce the amount of limescale attached to the furnace material.
It was found that 0.00% decomposition was achieved.
