Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a light-shielding device with a sterilizing function, and more particularly to a light-shielding device such as a curtain or a blind which has a sterilizing function by adhering titanium oxide to the surface of the body of the light-shielding device.

[0002]

[Prior art]

 Various kinds of bacteria are suspended in the air together with fine dust. And the health of these bacteria is not bad. And recently, nosocomial infections have become a major issue.

On the other hand, titanium oxide, which is a photocatalyst, has an action of killing various bacteria when it is irradiated with light. This is because when titanium oxide is irradiated with light, a strong redox reaction occurs on the surface of titanium oxide due to the energy of light, and as a result, bacteria in contact with this become a partner of electron transfer and cause great damage. It is thought to be because they receive it.

[0004]

[Problems to be solved by the device]

 The inventor of the present invention has been researching how to efficiently reduce various bacteria floating in the indoor air without using special equipment or extra cost. As a result, it was conceived to use titanium oxide having a strong bactericidal action as described above.

However, on the other hand, irradiation of light is indispensable for the bactericidal action of titanium oxide. Therefore, it was considered effective to use light-shielding equipment such as curtains and blinds that always receive sunlight in the room. And, it is cheap because it doesn't need any special equipment or cost to irradiate the sunlight.

Further, light-shielding tools such as curtains and blinds are attached to the windows, and the air in the room always flows by the air conditioning equipment and moves along the inner wall of the room, so that the air is always curtains or blinds. Touch the light-shielding equipment of.

Then, it was found that the intended purpose can be achieved by combining a light-shielding tool such as a curtain or a blind with titanium oxide, and the inventors have completed the present invention.

[0008]

[Means for Solving the Problems]

 The gist of the present invention is a light-shielding device with a sterilizing function, characterized in that titanium oxide is attached to the surface of the main body of the light-shielding device.

Titanium dioxide is preferably titanium dioxide, and when used, it has a diameter of 0. It is desirable to make particles of about 005 to 0.007 microns. Then, these fine particles of titanium oxide are applied to the body of the light-shielding tool by coating or other appropriate means. For example, in order to form a titanium oxide thin film on a blind slat, a known thin film forming technique such as an evaporation method or a sputtering method may be used.

Further, a curtain and a blind are desirable as a light-shielding tool for achieving the object of the present invention. In the case of a curtain, titanium oxide is attached to the surface of the curtain, and titanium oxide may be attached only to the surface on the side exposed to sunlight, but on both sides. If attached, the light from the indoor lighting can also be used, which is efficient. As a material for the curtain curtain, lace is preferable to cloth.

Further, in the case of a blind, particularly in the case of a Venetian blind, titanium oxide is attached to the surface of the slat. Also in this case, it is efficient if the slats are attached not only to one side but also to both sides.

Further, in the case of a roll blind, titanium oxide is attached to the surface of the cloth wound around the winding rod, and in this case also, it is desirable to attach it to both surfaces.

[0013]

[Action]

 Next, the operation of the present invention will be described. The air flowing along the inner wall of the room contacts curtains, blinds, and other shading devices. At that time, the bacteria in the air adhere to the body of the light-shielding device such as a curtain or a blind slat. And again, the bacteria come into contact with the titanium oxide.

In this state, when the titanium oxide is irradiated with sunlight or the light of an indoor illumination lamp, the energy of the light causes a strong redox reaction on the surface of the titanium oxide. As a result, the bacteria in contact with the titanium oxide act as an electron transfer partner, suffer serious damage, and die.
