Description

HAND DRIER WITH STERILIZER
Technical Field
The present invention relates to a hand drier with a sterilizer, and more particularly to a hand drier having a sterilizer, which can sterilize various germs on hands as well as dry the wet hands.
Background Art
In general, a hand drier provided in a bathroom to dry hands includes a housing having sucking openings and discharging ducts, heaters installed on the outlet sides of the discharging ducts to radiate heat, a driving motor mounted to the housing, blower fans pivotally installed to a rotating shaft of the driving motor to discharge the heated air, a detection sensor installed on the outer surface of the outlet side of the discharging duct to detect an object, a control unit electrically connected to the detection sensor to control the driving motor and the heater, and a power supply unit which supplies electric power to the control unit. In the conventional hand drier, if the detection sensor detects hands of a user, electric power is applied from the control unit to the power supply unit to operate the heater and the driving motor. Also, if the hands of the user are not detected, operations of the heater and the driving motor are stopped. On the other hand, various germs such as a coliform etc. live on hands of a human body, and the germs are not removed even when the hands are washed by soap. The germs cause many kinds of diseases including a contagious disease either in a public place or to an infant. Therefore, in order to sterilize the germs on the hands, a separate sterilizer should be used. However, it is not easy to use or keep the separate sterilizer. In addition, the separate sterilizer is an economical burden and it takes long time to both dry the wet hands and sterilize the hands. Disclosure of Invention
Therefore, the present invention has been made in view of the above- mentioned problems, and it is an object of the present invention to provide a hand drier having a sterilizer, which can sterilize various germs on hands simultaneously while drying wet hands. In order to achieve the above-mentioned object, the present invention installs ultraviolet ray lamps which irradiate ultraviolet rays outside on outlet side of discharging ducts of a hand drier which includes a housing, heaters, a driving motor, and blower fans, and reflection plates for reflecting the ultraviolet rays irradiated from the ultraviolet ray lamps are installed in the housing, and optical catalysts are coated on the outer peripheral surfaces of the reflection plates.
