Abstract

PURPOSE:To prevent the propagation of bacteria and to provide water which tastes good by decomposing away the suspended particles, iron rust or Bacillus subtilis, coliform bacilli and org. matter in water by means of a filter and UV rays and cooling the treated water. CONSTITUTION:A tank 6 having the filter 5 through which the treated water passes and a UV sterilizing lamp 9 is provided to a water treatment device body 1 and a cooler 21 is disposed near the treated water taps hole 22 of the tank 6. More specifically, the treated water past the filter 5 is exposed to the UV rays under stirring with a stirrer 12 and is cooled by the cooler 21. As a result, the suspended particles, iron rust or the Bacillus subtilis, coliform bacilli and org. matter in the water are surely decomposed and the treated water is cooled, by which the propagation of the bateria is prevented. The water which tastes good is thus obtd.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to the improvement of water treatment equipment, and particularly to the improvement of water treatment equipment, particularly for the removal of suspended particles, iron rust, Bacillus subtilis, and Escherichia coli, or the decomposition and removal of organic matter. related to a device for

[Conventional technology and its problems]

Conventionally, water treatment equipment used in cafeterias, coffee shops, station waiting rooms, etc. generally has a thread-like or sheet-like filter with precision and hyperfunction installed inside the water treatment equipment body, and water passes through the filter. This method is used to remove floating particles, iron rust, Bacillus subtilis, Escherichia coli, etc. contained in water.

However, according to this water treatment device, the filter becomes clogged with use, and its ability to remove suspended particles is poor, so it needs to be replaced at regular intervals.

In particular, if the pores of the filter are made small in order to increase the filter's transient function, there is a drawback that clogging is likely to occur.

Also, filters can remove suspended particles and iron rust in water, but they cannot remove all bacteria such as Bacillus subtilis and E. coli.
The disadvantage is that organic matter contained in water cannot be decomposed.

The present invention was developed in view of the above points, and uses a filter and ultraviolet light to eliminate suspended particles in water.

The purpose of the present invention is to provide a filtrate treatment device that can reliably decompose and remove iron rust, Bacillus subtilis, Escherichia coli, and organic matter.

[Means for solving problems]

The present invention will be explained below with reference to FIGS. 1 to 3. In the figure, reference numeral 1 denotes a housing-like main body of the device, which constitutes an upper chamber 2 and a lower chamber 3. 4 is a solenoid valve provided in the upper chamber 2,
It is configured to operate depending on the amount of water in the tank.

Reference numeral 5 denotes a filter housed in a cylinder connected to one end of the electromagnetic valve 4, and is, for example, a thread-like or sheet-like filter having micropores. 6 is lower chamber 3
The tank is constructed to have a narrow width near the lower end, and is configured to be able to store, for example, 10 to 201 J knots of water.

7 is a glass jacket disposed from the partition plate 8 toward the lower chamber 3, and 9 is an ultraviolet sterilization lamp mounted inside the glass jacket 7. For example, a lamp of about 12 watts is used. 10 is a cover for a socket 11 to which an ultraviolet germicidal lamp 9 is attached. 12 is a rotor blade 1 in the tank 6
3 a stirrer, 16 a discharge lamp ballast connected to the ultraviolet germicidal lamp 9, 14 a water level sensor mount,
Reference numeral 15 indicates a water level sensor connected to the water level sensor mount 14 and located inside the tank 6. Reference numeral 17 indicates a partition plate that is engaged with a stepped portion 19 of the narrow portion 18 near the lower end of the tank 6. This constitutes a hole 20. 21 is a cooler provided near the treated water outlet 22 of the tank 6; 23 is a compressor connected to the cooler 21; 24 is a water faucet;
25 is a water temperature adjustment unit, 26 is a ground terminal, and 27 is a power plug.

[Action of the invention]

The water treatment in the water treatment device described above will be explained.

(A) Pass the well water or tap water through the filter 5,
Inject into the tank 6. At this time, the filter 5 can remove floating particles, iron rust, Bacillus subtilis, Escherichia coli, and the like.

(B) Next, when the treated water that has passed through the filter 5 is stored in the tank 6, the ultraviolet germicidal lamp 9 is turned on, the rotor 13 is rotated, and the cooler 21 is operated. When 18 liters of water is stored in the tank 6 and a 12 watt ultraviolet germicidal lamp 9 is turned on, the ultraviolet sterilization lamp 9 will be discharged in about 10 minutes.
The 254 nm ultraviolet rays from the water remove Bacillus subtilis and E. coli contained in the water, as well as decompose and remove organic matter.

Although most of Bacillus subtilis and E. coli can be removed by the filter 5, there are some Bacillus subtilis and E. coli that cannot be removed by the filter 5 inside the tank 6, or Bacillus subtilis and E. coli that enter with the air from gaps in the water treatment equipment. can be completely removed by ultraviolet light.

(C) Furthermore, residual chlorine can be removed by ultraviolet rays, and treated water without any off-odor can be obtained.

(D) Furthermore, the water near the lower end of the tank 6 is cooled by the cooler 21 to prevent the growth of bacteria, and it is possible to obtain cold, delicious water.

〔Effect of the invention〕

As described above, the present invention provides a water treatment equipment main body with a filter through which treated water passes and a tank having an ultraviolet germicidal lamp, and a cooler near the treated water outlet of the tank, so that the treated water passes through the filter. After passing through, it is configured so that it is exposed to ultraviolet light while being stirred by a stirrer, and is cooled by a cooler, so that suspended particles, iron rust, Bacillus subtilis, and E. coli can be removed by a filter, as described above.

In addition, the ultraviolet germicidal lamp can reliably remove Bacillus subtilis and Escherichia coli, decompose and remove organic matter, and further remove residual chlorine, resulting in delicious water with no off-odor.

In addition, the water is cooled by the cooler, which has various advantages such as preventing the growth of bacteria and making it possible to obtain chilled, delicious water, making it very useful.
