(Prior Art and Problems to be Solved by the Invention) Conventional ultraviolet sterilizers use germicidal lamps or high-pressure mercury lamps as means for irradiating ultraviolet rays. However, in the case of germicidal lamps, the output of germicidal radiation decreases when the temperature drops, such as in winter. Also, the start-up of germicidal radiation when the light is turned on is delayed. On the other hand, high-pressure mercury lamps have also been used to compensate for the lack of germicidal radiation output at low temperatures, such as in germicidal lamps, but high-pressure mercury lamps have the disadvantage of increasing the size of the device. Regardless of which light source is used, it is difficult to make the device compact and still have high sterilizing power. (Illuminating Engineering Theory: New Edition, Lighting Data Book, P, 1G
? (Published by Ohmsha Co., Ltd.) The present invention was proposed in order to solve the above-mentioned drawbacks, and the purpose of the present invention is to provide an ultraviolet sterilizer that is compact and can provide high sterilization even at low temperatures. (Means for Solving the Problems) In order to achieve the above object, the present invention provides an ultraviolet sterilization device equipped with an ultraviolet lamp, characterized in that an electrodeless ultraviolet lamp is used as ultraviolet generation means. By using an electrodeless lamp that emits mercury using microwaves, the efficiency of ultraviolet light output is higher than that of a conventional mercury lamp that generates mercury using thermionic electrons from the electrode. Since there is no deterioration, the output can be increased, making the device compact and providing high sterilizing power even at low temperatures. (Function) With the above structure, the present invention allows the use of a small, high-output light source, making the device compact and providing high sterilizing power even at low temperatures. (Example) Next, an example of the present invention will be explained. It should be noted that the embodiments are merely illustrative, and it goes without saying that various changes and improvements can be made without departing from the spirit of the invention. FIG. 1 shows an embodiment of the ultraviolet water sterilization device of the present invention.

本発明によれば、紫外線ランプを備えた紫外線殺菌装置
において、紫外線発生手段として無電極の紫外線ランプ
を用いたことにより、装置がコンパクトで、しかも低温
時でも高い殺菌力を示すことができる効果を有する．In the figure, an inner tube 1 made of a cylindrical quartz glass tube and an outer tube 2 made of cylindrical hard glass are provided with an upper lid 3 at the top and a lower lid 4 at the bottom, and the inner tube 1 and the outer tube 2 are connected to each other. Between the running water part 5
The raw water inlet 6 is located below and the treated water outlet 7 is located above.
Establish. In addition, in the space 8 formed inside the inner tube 1, an electrodeless ultraviolet lamp 9 containing mercury vapor is provided.
Place. Electrodeless UV lamps have the advantage of being able to be designed in any shape, making them suitable for compact design. Furthermore, 10 is a temperature sensor, 11 is a heater, and 12 is a microwave oscillation unit that lights up a non-tti ultraviolet lamp 9 that is lit by microwaves. Next, the operation will be explained. In this ultraviolet running water sterilizer, drinking water is supplied from the raw water inlet 6 to the running water part 5, and is discharged from the treated water outlet 4. In addition, the lamp is turned on immediately before water is turned on. Using the above ultraviolet sterilizer, we investigated the sterilizing power of two light sources: a commercially available 6W germicidal lamp and an electrodeless lamp of the same size. Set the temperature of the germicidal lamp to 5°C. 15°C, 25°C, 35
After maintaining the temperature at 45°C and 45°C, a sterilization lamp was turned on and water containing Bacillus subtilis and Escherichia coli was passed through for sterilization. The number of bacteria in the sterilized water collected from the treated water outlet after 5 seconds and in the water before sterilization was counted using the agar plate method and the sterilization rate was evaluated. The results are shown in the table below. It should be noted that the present invention is not limited to the above-mentioned embodiments, and the explanation has been given to an internal illumination method in which a flow channel is provided between the inner tube and the outer tube and an ultraviolet lamp is placed inside the inner tube. It is clear that this method can be applied directly to various types of sterilization systems, including tank systems, external lighting systems in which an ultraviolet lamp is placed outside the water pipe, and other types of sterilization systems without being limited to running water. (Effects of the Invention) According to the present invention, in an ultraviolet sterilization device equipped with an ultraviolet lamp, an electrodeless ultraviolet lamp is used as the ultraviolet light generation means, so that the device is compact and exhibits high sterilizing power even at low temperatures. It has the effect of being able to
