Abstract

PROBLEM TO BE SOLVED: To provide an ultraviolet sterilizer for sterilizing equipment and the like with ultraviolet rays. SOLUTION: A lid 3 that can be opened and closed, a switch 2-1 that supplies and shuts off the power of a power supply unit to a light source in conjunction with the opening and closing of the lid, and a light source 5 that emits ultraviolet rays are built in to accommodate a sterilized object. The housing 2 to be sterilized, the power supply unit 4 that converts the AC voltage received from the commercial power source into a DC voltage and supplies power to the ultraviolet sterilizer, and the ultraviolet rays that are reflected and diffused to uniformly irradiate the sterilized object with ultraviolet rays. It is provided with an ultraviolet diffusing means 6 for sterilizing and a sterilizing process notifying means 7 for notifying the progress of the sterilizing process according to the lighting status of the light emitting diode.

Description

The present invention relates to a sterilizer for sterilizing equipment and the like for preventing contact infection by a virus.

Infectious diseases caused by coronavirus are widespread, and thorough measures to prevent infectious diseases are desired. As one of the infection prevention measures, sterilization of equipment and the like commonly used by a plurality of people is effective.

However, with regard to coronavirus, there is no specific guideline on how to sterilize with ultraviolet rays, and the current situation is that it depends on individual judgment as to what kind of light source is effective, the wavelength of light, and the irradiation time, and it is always preventive. The current situation is that the measures are not thorough.

Further, in stores and the like visited by an unspecified number of people, it is desired to develop means for efficiently sterilizing equipment such as writing tools.

At present, a small and easy-to-use sterilizer that can be installed in stores and the like has not been developed.

Japanese Unexamined Patent Publication No. 11-767273

The problem to be solved is to provide a small and inexpensive sterilizer that efficiently and effectively sterilizes writing tools, documents, etc. used by an unspecified number of people in stores and the like.

The present invention provides an ultraviolet sterilizer equipped with a plurality of light sources that radiate ultraviolet rays in a housing that blocks ultraviolet rays, and further includes a scattering plate that scatters the ultraviolet rays and uniformly irradiates the object to be sterilized.

The ultraviolet sterilizer of the present invention has a sterilizer built in a housing that can also be used as furniture for desks, chairs, etc., so that it is not necessary to install a separate sterilizer in the housing that blocks ultraviolet rays. By incorporating a light source, it is possible to realize safety and space saving.

FIG. 1 is an external view of an ultraviolet sterilizer.

An ultraviolet sterilizer is built in furniture to provide an ultraviolet sterilizer capable of sterilizing writing tools and the like.

FIG. 1 is an external view of an embodiment of an ultraviolet sterilizer. The ultraviolet sterilizer 1 is composed of a housing 2, a power supply unit 4, a light source 5, an ultraviolet diffusing means 6, and a sterilization process notification means 7. The housing 2 is made of a metal material capable of blocking ultraviolet rays, and includes a lid portion 3 that can be opened and closed. Further, it is provided with a switch 2-1 that turns on / off the power supply in conjunction with the opening / closing operation of the lid. The power supply unit 4 is a power source for driving the device by commercial power and a battery, and turns on / off the power supply in conjunction with the switch 2-1. The light source 5 is composed of a light source such as a discharge lamp or an LED that emits ultraviolet rays. The ultraviolet diffusing means 6 is arranged to face the light source, reflects and diffuses the ultraviolet rays radiated from the light source, and uniformly irradiates the sterilized object with the ultraviolet rays. The sterilization process notification means 7 is composed of light emitting diodes and buzzers of a plurality of colors, and is a notification means for notifying the end of the sterilization process by light and sound. Depending on the progress stage of the sterilization process, the progress process may be notified by changing the emission color. It is also possible to provide a timer and change the irradiation time according to the object to be sterilized.

The ultraviolet sterilizer of the present invention can contribute to sterilization of clothes, shoes, etc. by installing it not only in furniture such as desks and chairs, but also in lockers and lower leg boxes.
