本考案は、紫外線殺菌ランプと活性炭カートリ
ツジとを組合せた小形浄水器に関するものであ
る。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a small water purifier that combines an ultraviolet germicidal lamp and an activated carbon cartridge.
昨今、水道水は恒常的に水質汚濁の状態とな

ゆるバイパス利用タイプとに分けられる。
In recent years, tap water has become constantly contaminated, and water purifiers have become popular as a countermeasure. Activated carbon, ion exchange resins, ultraviolet sterilizing lamps, calcium carbonate filter media, and the like are used in water purifiers, and these are used alone or in appropriate combinations. The structure of the small water purifier can be broadly classified as follows. In other words, there are two types: types that are connected directly to the faucet, and tank types such as tabletop pots. There are two types: the so-called bypass type, in which water is discharged from the faucet again.
かかるバイパス利用の浄水器は、実公昭53−
24128号公報にもみられるごとく、浄水器自体が
任意の場所に据付けられるので、若干大型化して
も、例えば流し台の内部にも据付けられることか
ら、流し台上の空間を占めることがない、という
長所を備えている。 Such a bypass-based water purifier was developed in 1973.
As seen in Publication No. 24128, the water purifier itself can be installed in any location, so even if it is slightly larger, it can be installed inside the sink, for example, so it does not occupy the space above the sink. We are prepared.
その反面、かかるバイパス利用の浄水器ではホ

浄水器の処理能力の低下は歪めなく、したがつ

つている。 On the other hand, in water purifiers that use bypass, water channels such as hoses are long, and the reduction in water pressure does not affect the processing capacity of the water purifier. It is unsuitable for vessels, especially small ones.
一方、活性炭カートリツジと紫外線殺菌ランプ

ンプによつて、浄水器内の水温が上昇し、その水
温上昇により活性炭の吸着機能が劣化する、とい
う不都合があつた。 On the other hand, in a water purifier that combines an activated carbon cartridge and an ultraviolet germicidal lamp (for example, see Utility Model Application Publication No. 60-248284), each function is synergistically performed, but there are various problems when handling the water purifier by women and girls. This is causing inconvenience. For example, if you forget to turn off an ultraviolet germicidal lamp, there will be no problem with the UV germicidal lamp itself, but the water temperature in the water purifier will rise due to the ultraviolet germicidal lamp, which converts more than 90% of the electricity into heat. However, there was a problem in that the adsorption function of activated carbon deteriorated due to the rise in water temperature.
したがつて、吸着機能維持のめ、前掲の特開昭
60−248284号公報の浄水器では、活性炭カートリ

ツチを浄水貯水殺菌室の水量によつて作動される
フロートスイツチを採用して自動的に点滅させて
いる。 Therefore, in order to maintain the adsorption function,
In the water purifier disclosed in Publication No. 60-248284, an activated carbon cartridge is installed above to allow hot water to flow down without accumulation, and the switch for the ultraviolet sterilization lamp is a float switch that is activated depending on the amount of water in the purified water storage sterilization chamber. It is adopted and flashes automatically.
しかしながら、かかる浄水器では活性炭に温水

チを使用すれば、それだけ、浄水貯水殺菌室を大
きくしなければ、蛇口の開閉による水面の乱れで
フロートスイツチが影響されるので、小形の浄水
器には適用できない、という問題がある。 However, since such water purifiers do not store hot water in the activated carbon and are equipped with a purified water storage sterilization chamber, they are inevitably large-sized water purifiers (for example, those used in hospitals and restaurants), and so-called bypass use is required. There is a problem in that it cannot be applied to small water purifiers. Moreover, if a float switch is used, the problem is that unless the purified water storage sterilization chamber is enlarged, the float switch will be affected by disturbances in the water surface caused by opening and closing of the faucet, so it cannot be applied to small water purifiers. .
一方、浄水器において、紫外線殺菌ランプを開
閉する圧力スイツチが適用された例が散見される
が（例えば、実公昭40−13826号公報、実公昭70
−12541号公報参照）、これらの圧力スイツチはい
ずれも吸上げポプの配管中などに設けられたもの
で、所定の圧力が常に得られ、圧力スイツチの作
動は正確に行われる。 On the other hand, there are some cases where water purifiers are equipped with pressure switches that open and close ultraviolet germicidal lamps (for example, Publication of Utility Model Publication No. 40-13826, Publication of Utility Model Publication No. 70
(Refer to Publication No. 12541), all of these pressure switches are installed in the suction pop piping, etc., so that a predetermined pressure is always obtained and the pressure switches operate accurately.
しかしながら、いわゆるバイパス利用の小形浄
水器では、前記ように水圧の低下は歪めないこと
から、これらの公報に示された圧力スイツチはそ
のまま適用できない、という問題がある。 However, there is a problem in that the pressure switches disclosed in these publications cannot be directly applied to small water purifiers that utilize so-called bypass, since the drop in water pressure does not distort the water pressure as described above.

a, the ultraviolet germicidal lamp 28 is turned on by the glow starter or the electronic starter 35, and the pilot lamp 37 is turned on. The raw water flowing through the throttle hole 14 passes through the lower filter 1
9. The activated carbon 21 and the upper filter 20 are raised and filtered. Meanwhile, chlorine in the raw water,
Dust, turbidity, iron rust, trihalomethane, and even odors are removed. Next, the purified water flows into the intermediate passage 9 through the overflow hole 17 and ascends the sterilizing cylinder 7. During this time, bacteria passing through the activated carbon 21 are sterilized by an ultraviolet germicidal lamp 28. for example,
E. coli and other bacteria are immediately sterilized. Completely purified purified water is then discharged from the purified water outlet 3' via the bypass pipe P and the switching valve V.

め度々交換する必要はない。 Here, since the adsorption power of the activated carbon 21 deteriorates over time, if the water purifier K is used every day, it is necessary to replace it once every six months, but in this embodiment, the upper filter The guideline is to replace the ring when it becomes the same color as the standard brown ring. In that case, remove the cover body 2 from the base 1, remove the fixing bolts 23, and press the tongue piece 22 onto the holding piece 2.
4, remove the activated carbon cartridge 5, and replace the filters 19, 20 and activated carbon 21. Also, new filter 19,
20 and replaced with a new cartridge 5 filled with new activated carbon 21. On the other hand, since the ultraviolet sterilization lamp 28 has a usage period of, for example, 2000 hours, it is not necessary to replace it frequently.

According to the present invention, in a so-called bypass water purifier that is attached to a water faucet via a bypass hose for raw water and purified water, the raw water inlet,
Since the sterilization tube and the activated carbon cartridge with a check valve are installed in series, the inlet passage can be made as long as possible, ensuring the amount of water in the inlet passage, and the check valve. Since the water pressure was also secured, the operation of the pressure switch using the diaphragm could be ensured.

ては、活性炭の吸着性能を劣化させない。 Therefore, although the water pressure of small water purifiers that use so-called bypass tends to be low, the ultraviolet sterilization lamp can be reliably flashed by simply turning the faucet, making it extremely easy to use and making it possible to purify water. This prevents the water temperature within the vessel from rising, and in turn, prevents the adsorption performance of activated carbon from deteriorating.

支障を与えない。 In addition, the pressure switch of the present invention has an extremely simple structure, as it is operated by cutting out a part of the upper wall of the through-hole-shaped inlet passage, attaching a diaphragm there, and deforming the diaphragm. Do not interfere with the flow of raw water.
