Suitable for use in places where health care is required. Moreover, since it can be manufactured at a low cost without requiring a large space, it can be used in ordinary homes.

FIG. 1 is a front view of the ultraviolet sterilizer according to the present invention. FIG. 2: is the top view which represented simply the state in the baseplate part of the ultraviolet sterilizer in Example 1. FIG.

  Hereinafter, embodiments of the present invention will be described by way of example with reference to the drawings.

  In the figure, 1 is an ultraviolet sterilizer, 2 is a housing which is a cover case of the ultraviolet sterilizer 1, and is formed on an elongated shape. The housing 2 is composed of a bottom plate portion 2a serving as a substrate and an upper lid portion 2b which covers and fixes the upper portion of the bottom plate portion 2a to form a housing, and is in the form of a substantially rectangular cylindrical body in longitudinal section. In addition, the housing 2 has a shielding structure so that ultraviolet light does not leak to the outside of the housing 2 in order to prevent damage to the body such as inflammation of the eyes and skin due to strong ultraviolet light radiated inside.

  FIG. 2 is a plan view simply showing the configuration in the bottom plate 2a with the upper lid 2b removed, and one end (bottom side in the drawing) of the bottom plate 2a is in the sterilizer 1 A fan 3 is provided to supply air. In addition, a filter 4 is provided at the other end (right side in the drawing) to filter out dust such as dust and dirt in the air and sterilize the air supplied into the sterilizer 1. It is supposed to be released outside. Although the material of the filter 4 is not particularly limited, it is desirable to use an ozone filter which adsorbs and decomposes ozone which may be generated by ultraviolet irradiation. The air supply fan 3 and the filter 4 are formed so as to respectively shield the open end of the substantially cylindrical cross section of the casing 2.

  In addition, between the fan 3 and the filter 4 on the bottom plate portion 2a, a straight tubular ultraviolet lamp 5 along the shape of the housing 2 is provided at both ends by the sockets 6, 6 disposed on the bottom plate portion 2a. Is attached by being supported and fixed. The ultraviolet lamp 5 is a light source of ultraviolet light, and sterilizes and sterilizes bacteria, viruses, molds, bacteria and the like suspended in the air by the irradiation of the ultraviolet light. The wavelength of the ultraviolet light of the ultraviolet lamp 5 is less than 280 nm called UVC, and a strong germicidal effect can be obtained by using a UVC lamp. The ultraviolet lamp 5 is preferably made of, for example, quartz glass, calcium fluoride, or magnesium fluoride.

  A reflector (not shown) is preferably provided between the bottom plate portion 2 a and the ultraviolet lamp 5 in order to increase the reflection efficiency of ultraviolet light. The reflection plate is disposed in a horizontally long shape along the length direction of the ultraviolet lamp 5 and is formed of a rectangular curved plate-like concave concave mirror made of a rectangular curved plate curved in a substantially semicircular shape along the circumferential direction of the ultraviolet lamp 5 Preferably, the reflection surface of the reflection plate is disposed to face the ultraviolet lamp 5.

  The sterilizing apparatus 1 is installed by attaching the bottom plate portion 2a to a wall, a ceiling or the like, and covering the bottom plate portion 2a with the upper lid portion 2b. The bottom plate 2a and the upper lid 2b are fixed by screws 2c in the front of the housing 2 in the illustrated example. In FIG. 2, the arrows indicate the direction of air flow, and when the sterilizer 1 is operated by the sterilizer 1 or a switch (not shown) formed outside, air is introduced into the sterilizer 1 by the air supply fan 3. Supplied, the ultraviolet light from the ultraviolet lamp 5 destroys DNA in bacteria such as bacteria, viruses, molds, bacteria, microbes, etc. in the air, and these dead bodies and dusts are filtered by the filter 4 to form molds, viruses, bacteria and bacteria. Clean air from which microorganisms etc. have been removed is released out of the sterilizer 1.

  Since the air irradiated with ultraviolet rays reduces microorganisms that feed on mold and bacteria, the growth of indoor mold can be suppressed, and the air cleaned by the sterilizer 1 prevents infections such as influenza and the like It is possible to prevent nosocomial infections in hospitals and the like.

  Table 1 shows the amount of bacteria contained in the air of common bacteria (bacteria) and fungi (mold) 24 hours after the start of use and 48 hours after the start of use before using the sterilizer 1 in a room (17 cubic meters) It is the survey result surveyed. In the table, B indicates bacteria and F indicates mold. As apparent from this table, after the use of the sterilizer 1, the numbers of bacteria and fungi decrease dramatically, and the remarkable bactericidal effect of the sterilizer 1 can be confirmed.
