It produces ultraviolet rays.

Referring to Figure 1, in the prior art, in order to manufacture sterilized water, an electrodeless ultraviolet lamp (31) is located in the inner center of the sterilized water generation tank (11), The water flowing into (11-1) is exposed to microwaves and ultraviolet rays until it exits the drain hole (11-2) located at the top of the other side, but to ensure the exposure time required for sterilization, the flow rate of sterilization water generation is constant. Since it cannot be increased beyond the limit, it is unsuitable for use in large demand areas such as swimming pools that require a large amount of sterilized water in a short time.

On the other hand, in order to increase the flow rate of sterilized water generation, the size of the electrodeless UV lamp and the sterilized water generation tank may be increased, or a plurality of devices may be installed in parallel, but this is not preferable because the manufacturing cost and operating efficiency are very low and economic efficiency is low.

The magnetron 30 is on the central axis (z) of the sterilized water generating tank 10 from the upper side of the sterilized water generating tank 10 to irradiate microwaves into the electrodeless ultraviolet lamp 20 and the quartz tube 21 Is placed in. A waveguide 31 and a microwave injection chamber 32 are installed between the magnetron 30 and the upper and lower fixtures 14 located on the upper side of the sterilized water generating tank 10. Therefore, the microwave generated by the magnetron 30 is irradiated to the electrodeless ultraviolet lamp 20 through the waveguide 31 and the injection chamber 32, so that the electrodeless ultraviolet lamp 20 generates ultraviolet rays, and The microwave irradiated into the tube 21 passes through the transparent quartz tube 21 along with the ultraviolet rays generated from the electrodeless UV lamp 20 and is irradiated into the interior of the sterilized water generating tank 10 to generate the sterilized water generating tank. (10) It will sterilize the water flowing inside.

On the other hand, as shown in Figure 2, the present invention, unlike the prior art, to increase the length of the flow path of the water flowing inside the sterilized water generating tank 10 to secure a sufficient sterilization time by ultraviolet rays and microwaves A plurality of partition walls 40 disposed along the axial direction are provided between the quartz tube 10 and the quartz tube 21.

Further, a plurality of through-holes 41 are formed in the partition wall 40 so that the central axes thereof face each other and have an inclined shape based on a line (xx) connecting the central axes of the water inlet 11 and the drain outlet 12. By forming, the flow of water flowing through the plurality of through-holes 41 collide with each other and promote mixing, thereby enhancing the sterilization effect by microwaves and ultraviolet rays.

In addition, the partition wall 40 is provided with a plurality of protrusions 42 so that an embossed pattern is formed on the surface of the portion where the through hole 41 is not formed, thereby promoting turbulent flow on the surface of the partition wall due to friction on the partition wall surface. While lowering the flow resistance and promoting the mixing of water, it helps to make the density of microwaves and ultraviolet rays uniform in the space between the partitions 40.
