Description

TECHNICAL FIELD The present invention relates to an improvement of a water treatment device, and more particularly to a device for removing Bacillus subtilis and Escherichia coli contained in water and decomposing organic matter.

[Conventional technology and its problems]

Conventionally, a water treatment device used in a cafeteria, a coffee shop, a waiting room of a station, etc. is equipped with an ultraviolet sterilization lamp housed in a cylinder inside the body of a water treatment device in the form of a tank. Ultraviolet rays of 254 nm are used to remove Bacillus subtilis and Escherichia coli contained in water and decompose organic matters.

However, according to this device, when water is run through the inside of the main body of the water treatment device, the sterilizing effect of the water flowing near the ultraviolet sterilization lamp is high, but the sterilizing effect of the water flowing far is incomplete, and it is not When the amount of water in the main body of the water treatment device is reduced and tap water is replenished, the water treated with ultraviolet rays and the replenished water are mixed and cannot be used as treated water unless sterilized for a new period of time.

[Object of the Invention]

The present invention has been made in view of the above points and has a high sterilizing effect, and can provide a treated water that can continuously use treated treated water and can obtain treated water having no offensive odor. The purpose is to do.

[Means for solving problems]

The present invention will be described below with reference to FIGS. In the figure, reference numeral 1 is a housing-shaped device body, which is composed of an upper chamber 2 and a lower chamber 3. Reference numeral 4 denotes a tank housed in the lower chamber 3, which has a narrow width in the vicinity of the lower end, for example, 10 to
It is designed to store 20 liters of water. 5 is a glass jacket arranged from the partition plate 6 toward the lower chamber 3,
Is an ultraviolet sterilization lamp mounted inside the glass jacket 5, for example, a lamp of about 12 watts is used.
Reference numeral 8 is a cover of the socket 9 on which the ultraviolet sterilization lamp 7 is mounted. Reference numeral 10 is a solenoid valve provided in the upper chamber 2 and is configured to operate depending on the amount of water in the tank. 11 is a stirrer having a rotary blade 12 in the tank 4, 13 is a ballast for a discharge lamp which is connected to an ultraviolet germicidal lamp 7, 14 is a water level sensor mount, and 15 is a water level sensor mount 14, and the inside of the tank 4 is connected. The water level sensor 16 is a partition body that is engaged with the step portion 18 of the narrow portion 17 of the tank 4, has a lamp insertion hole 19, and has a plurality of constituent bodies 20 at predetermined intervals. And stack them together to form a structure 20
It is configured to have a plurality of holes 21 inward and at different positions.

The distance between the two structures 20 is, for example, 10 to 20 mm.

26 is a cooler provided below the tank 4, 22 is a cooler 26
Is a compressor, 23 is a faucet, 24 is a water temperature control unit, and 25 is a power plug.

[Operation of the invention]

The treatment of water in the above-mentioned water treatment device will be described.

(A) Well water or tap water is poured into the tank 4, and when the amount of water reaches a predetermined amount, the ultraviolet sterilization lamp 7 is turned on, the rotary blades 12 are rotated, and the cooler 26 is operated.

When 18 liters of water is supplied to the tank 4 and the 12 watt ultraviolet sterilization lamp 7 is turned on, the Bacillus subtilis and Escherichia coli contained in the water are removed and the organic matter is decomposed by the ultraviolet ray 254 nm from the ultraviolet lamp 7 in about 10 minutes. Remove.

(B) Further, the treated water treated with ultraviolet rays flows under the partition 16 and is cooled by the cooler 26.

Since the treated water flows under the partition body 16, when fresh water is supplied, the treated water does not mix with the water before the treatment, and the treated water can be continuously taken out.

Further, since the lower part of the tank 4 is cooled by the cooler 26, it is possible to prevent the growth of bacteria and obtain cool tasty water.

Further, residual chlorine is removed by ultraviolet rays, and water having no offensive odor can be obtained.

(C) Further, the water supplied into the tank 4 flows to the lower side of the partition plate 16 through the holes 21 formed in plural in the two constituent bodies 20 at different positions inside, so that the water is totally Further, the ultraviolet sterilization lamp 7 is approached, and it is possible to effectively sterilize Bacillus subtilis, Escherichia coli light by ultraviolet rays and decompose organic substances.

〔The invention's effect〕

As described above, the present invention provides an ultraviolet sterilization lamp and a stirrer inside the tank of the main body of the water treatment device, and a predetermined interval is provided between the lower part of the ultraviolet sterilization lamp and the inner wall of the tank. Provide a partition body that stacks multiple components,
Since a plurality of holes are formed inside the same structure and at different positions, the function of the partitioning body prevents the treated water and the untreated water from being mixed when replenishing the water. , Treated water can be continuously obtained.

In addition, since the water supplied into the tank flows through the holes near the ultraviolet sterilization lamp to the lower side of the tank, it is possible to effectively remove Bacillus subtilis, Escherichia coli and decompose organic matters.

Furthermore, since the lower part of the tank is cooled by a cooler, the growth of bacteria is prevented, and the residual chlorine is removed by ultraviolet rays, so it has the advantages that it can obtain cool tasty water without odor and is useful. The nature is great.
