Benefits of technology
The patent text describes a device that uses ultraviolet light to deactivate bacteria on the human body while avoiding harmful effects on human cells. The device emits ultraviolet light with a specific wavelength range, which prevents harmful UV rays from affecting the human body. The technical effect of this patent is the development of a safe and effective device for sterilizing and drying objects, including part of the human body.
Problems solved by technology
This wavelength sterilizes bacteria such as Escherichia coli (O-157) and Staphylocaccus aureus (MRSA), but can harm the human body.
The hand dryer-sterilizer of Japanese Patent Application Laid-Open Publication No. 2011-142930 does not mention the wavelength of the ultraviolet light emitted from the ultraviolet sterilization lamp, but mentions that it adversely influences the human eyes.
Accordingly, if the technologies of Japanese Utility Model Registration No. 3157460 and Japanese Patent Application Laid-Open Publication No. 2011-142930 are used, there is a possibility that normal cells of a human body would seriously be damaged as an accumulated amount of irradiation of the ultraviolet light to the hands from the ultraviolet sterilization lamp increases.
Thus, there is a serious concern to a human's health, e.g., photo-aging and skin cancer may occur when an accumulated amount of irradiation of the ultraviolet light to the hands from the ultraviolet sterilization lamp increases.

Embodiment Construction
[0057]Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0058]General Structure of a Dry Sterilizing Device
[0059]FIG. 1 is a perspective view that shows an exemplary structure of a dry sterilizing device 100 according to an embodiment of the present invention. FIG. 2 is a side view of the dry sterilizing device 100.
[0060]The dry sterilizing device 100 of this embodiment is a device for drying and sterilizing wet hands and fingers of a human when he / she washes hands and fingers with water. The dry sterilizing device 100 may be installed at hand-washing places in facilities such as hospitals, nursing homes and food factories. These facilities demand good sanitation.
[0061]As shown in FIG. 1, the dry sterilizing device 100 has a housing 101. The housing 101 has an opening 102 at its upper portion. The opening 102 opens upward. The housing 101 has an inner bottom 103 at its lower part. The inner bottom 103 is opposite to the ...

A sterilizing device includes a housing having an opening in at least one direction thereof. The housing also has a hollow portion configured to allow insertion of an object (target) including part of a human body from the opening into the hollow portion. The sterilizing device also includes at least one air blower unit configured to send a flow of air toward an interior of the hollow portion, and at least one ultraviolet light emitting unit configured to emit ultraviolet light toward the interior of the hollow portion. The ultraviolet light emitted from each ultraviolet light emitting unit includes at least part of ultraviolet light having a wavelength between 190 nm and 230 nm and at least part of ultraviolet light having a wavelength between 230 nm and 237 nm, but does not include ultraviolet light having a wavelength below 190 nm and beyond 237 nm.
Description
FIELD OF THE INVENTION[0001]The present invention relates to a device that dries and sterilizes an object including part of a human body, such as a wet hand, and also relates to a method of drying and sterilizing an object including part of a human body, such as a wet hand.DESCRIPTION OF THE RELATED ART[0002]A hand dryer is used to quickly remove water droplets from wet hands and wet fingers after washing the hands. The hand dryer is a device for sending a warm current of air to the wet hands and fingers to dry the hands and fingers. Because the hand dryer is convenient, easy to install and easy to use, it has become widespread at hand-washing places in building such as business buildings, commercial facilities and schools.[0003]On the other hand, sanitation is more important to hospitals, nursing homes and food factories, and sterilization and disinfection of bacteria are strongly required. Thus, these facilities use devices for drying and sterilizing the hands and fingers to steri...
