Ultraviolet rays can be divided into 4 kinds of UV-A, UV-B, UV-C and UV-D, and the wavelength used for sterilization is UV-C wavelength. Among them, the wavelength of 253.7 nm is known to be almost the same as the wavelength most lethal to the DNA of bacteria or viruses. The wavelength emitted from the first and second ultraviolet lamps 210 and 220 in the present invention should preferably be the above wavelength and this wavelength affects the DNA of the bacteria or the virus and is almost killed or harmlessly changed to prevent the propagation do.

Viruses and bacteria are especially vulnerable to ultraviolet rays, so ultraviolet disinfection can be effective, and disinfection time is short compared to other disinfection methods (2 to 7 seconds in the case of bacteria). Unlike the method of using drugs, remnants remain after disinfection There is an advantage in not doing so.

The first ultraviolet lamp 210 is provided at one side of the accommodating space of the main body 100 and emits ultraviolet rays in an orthogonal direction toward the door handle 20.

The second ultraviolet lamp 220 may be installed at an angle to the door handle 20 in a direction orthogonal to the door handle 20 so as to be sterilized. Since the ultraviolet ray irradiation amount is proportional to the contact time of the ultraviolet ray, when the second ultraviolet ray lamp 220 is inclined at a predetermined angle with respect to the orthogonal direction, And the irradiation range of the ultraviolet rays can be variously adjusted to effectively sterilize the hand portion of the human body located in the hand receiving portion 110B of the door handle 20.

For example, the first human body detection sensor 310 is disposed on the upper side of the opening 120B of the cover plate 120, and the second human body detection sensor 320 is disposed on the upper side of the opening 120B of the cover plate 120, And may be installed on the lower side with respect to the first side 120B.

By positioning the first human body detection sensor 310 above the second human body detection sensor 320, even if the children approach the second human body detection sensor 320 normally with the play, the first human body detection sensor 310 The ultraviolet lamp module 200 can be prevented from being operated as a whole to prevent a malfunction due to prank by children.

The controller 400 detects the human body by the first human body sensor 310 located on the front face of the cover plate 120 among the plurality of human body detection sensors 300 and detects the human body 110B It is determined that the person is preliminarily approaching the door handle 20 so that the ultraviolet lamp module 200 is controlled to the pre-sterilization mode, and when a plurality of When the first human body sensor 310 and the second human body sensor 320 of the human body detection sensor 300 detect the human body, it is determined that the hand of the person is currently approaching the door handle 20, Thereby controlling the lamp module 200 to the normal sterilization mode.

The control unit 400 preferably turns off the ultraviolet lamp module 200 if no human body is sensed by the human body sensor 300 so that the power consumed by the ultraviolet lamp module 200 is minimized.

The protrusion plate 130 of the main body 100 is coated with a photocatalyst 130A in a direction facing the first and second ultraviolet lamps 210 and 220. The photocatalyst is a kind of semiconductor ceramics, and refers to a material that generates strong oxidizing power on a surface when irradiated with a wavelength of 400 nm or less and ultraviolet rays of about 3.2 eV or more. As a typical photocatalyst, titanium dioxide is used.

Titanium dioxide absorbs ultraviolet rays generated from an ultraviolet lamp to generate electrons and holes. These electrons and holes each have a strong reducing power and an oxidizing power. Especially, holes are reacted with water and dissolved oxygen to generate OH radical ) And active oxygen.

Therefore, the OH radical energy is higher than the binding energy of the molecules constituting the organic substance, and thus it is cut and decomposed, so that it is applied to the decomposition / harmfulization of various harmful chemical substances and odor substances contained in the air.

The titanium dioxide photocatalyst 130A is applied to the protruding plate 130 of the main body 100 to disinfect and sterilize the periphery of the hand accommodating portion 110B through ultraviolet rays irradiated from the first and second ultraviolet lamps 210 and 220 Function can be performed.
