ようとする課題）
しかしながら、銀添着活性炭は、雑菌の繁殖をある程度
抑えうるが、制菌力は強いものではなく、また銀の溶出
があり、処理方法によっては１０〜５ｏｐｐ−という有
害な量の銀が水の中に溶けこむという欠点もある。As a method for removing bacteria or preventing their proliferation, silver-impregnated activated carbon is used (for example, in Japanese Patent Application Laid-Open No. 57-1325
No. 85) Those applying ultra-micro filters using hollow membranes (for example, JP-A-58-131187, JP-A-61-171593, JP-A-62-
(Publication No. 30507) has been proposed (Problems to be Solved by the Invention) However, although silver-impregnated activated carbon can suppress the growth of bacteria to some extent, it does not have strong bactericidal activity, and silver may be leached. However, depending on the treatment method, a harmful amount of 10 to 5 opp of silver can be dissolved in the water.
また中空系フィルターは、銀活性炭では抑えられない雑
菌やカビなどの微生物や鉄サビなどの不純物の除去が可

ターを買い換えてくれるかどうかという問題も含まれて
いるのが実情である。Additionally, hollow filters are an effective means of removing impurities such as germs, mold, and other microorganisms that cannot be suppressed with silver activated carbon, and impurities such as iron rust. The shortcomings are that the filter life is extremely short and the initial cost is high, and the reality is that there is also the issue of whether consumers will buy a new filter when it has reached the end of its life.
本発明は、上記の欠点を改善するために提案されたもの

用を有する。(Function) The necessary functions of a sterilizer that should be incorporated into a water purifier are to ensure the sterilization of general bacteria that enter from city water, to suppress the proliferation of bacteria within the water purifier, and to remove water from the faucet. It should have two functions: to sterilize bacteria that enter the air as airborne bacteria. The inventors satisfied this point and developed a long-life, compact sterilization device that uses a double-back system that can share a conventional ultraviolet lamp. In other words, the sterilizing lamp does not need to be restricted in shape or lighting method, and any lamp that emits a wavelength of 254n- may be used. By dividing the water into two systems, it is possible to sterilize the water to be treated.The inlet side of the water purifier, that is, the sterilization of bacteria contained in city water, and the outlet side of the water purifier, that is, sterilization of bacteria contained in the water from the faucet. By preventing contamination, it has the effect of ensuring thorough sterilization, which is the role of a water purifier.

In the figure, l is the water outlet of the sterilizing section on the inlet side of the water purifier, 2 is the water inlet of the sterilizing section on the inlet side of the water purifier, 3 is the water outlet of the sterilizing section on the outlet side of the water purifier, and 4 is the water inlet of the sterilizing section on the outlet side of the water purifier. , 5 is a germicidal lamp, 6 is a quartz glass tube, 7 is a hard glass tube, 8 is an upper lid, 9 is a lower lid,
10 is a hot air generator, 11 is a lighting device and a temperature control device, 12 is a double front partition plate, 13 is a temperature sensor, 14 is a water purifier first water flow section, and 15 is a water purifier second water flow section, in further detail. Then, the first water flow part 14 and the second water flow part 1 in the water purifier system
5 is obtained by vertically dividing a double tube made of a quartz glass tube 6, a hard Pyrex glass tube 7, an upper cover 8 and a lower cover 9 into two by a partition plate made of a hard Pyrex glass plate. Therefore, the water to be treated at the inlet of the water purifier enters from the water outlet 2, exits from the water outlet 1, flows toward the activated carbon and filter that removes the chlorine odor and impurities in the water purifier, and finally comes out from the faucet. Before, enter the flowing water through the pipe again from the flowing water population 4 and exit from the flowing water outlet 3,
The water is supplied as drinking water.

が作動するようになっている。A 15W sterilizing lamp 5 is placed in the center of the quartz glass tube 6, and is turned on when water to be treated flows through the double tube to exhibit a sterilizing effect. In addition, a temperature sensor 1 is installed in a part of the germicidal lamp.
3, and operates in conjunction with the temperature control circuit 11 so that the surface temperature of the lamp is always between 30 and 40°C.
is now operational.

された。Contains 1 water! ! The water is passed through this at a rate of 2 to 31/min so that it comes out of the outlet 1, and the water that comes out of the outlet 1 is collected 3 seconds after the lamp is turned on.
Bacterial counts were checked using the agar plate method. Similarly,
Water was passed for 317 minutes so that the water entered from the water outlet 4 and exited from the water outlet 3, and the number of bacteria in the passing water was checked. The results showed that the number of bacteria was zero in both cases, confirming that they had a great bactericidal effect.
さらに流量を増大していって、殺菌効果を調べたところ
５１／分まで殺菌が完全であることがわかった。When the flow rate was further increased and the sterilization effect was examined, it was found that sterilization was complete up to 51/min.
