Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an air sterilizer.

[Conventional technology]

Air sterilizers equipped with sterilizing lamps are installed in food manufacturing plants, commercial kitchens, hospitals, etc. in order to maintain a sanitary environment.

[Problems to be solved by the device]

By the way, conventionally, the said sterilization apparatus was independently installed as equipped with only a sterilization lamp. If this is done, the normal lighting device will be installed separately, and this is not preferable because the ceiling part becomes complicated, and furthermore, it is necessary to perform the installation work for the sterilizer and the normal lighting device separately. It was From the sterilizer, blue visible light is also emitted in addition to ultraviolet rays, but since this visible light was directed toward the room as it was, the natural color of food, dishes, etc. was impaired, In a hospital,
It was not preferable because the complexion of the sick person looked even more different. Since the sterilizer did not function as a lighting device, it did not contribute to energy saving from the viewpoint of lighting.

In view of such circumstances, the present invention eliminates the complexity of the ceiling part, simplifies the installation work, prevents the natural color of foods from being damaged, and contributes to energy saving. It is an object of the present invention to provide an air sterilization device having the above structure.

[Means for Solving the Problems]

In this invention, in order to solve the above-mentioned problems, at least,
It has a case where the surface that will be directed to the indoor side is a surface that blocks ultraviolet light and that allows visible light to pass, and the surface that will be directed to the opposite indoor side is a surface that transmits ultraviolet light. And a complementary color lamp that emits light having a complementary color relationship with visible light emitted from the lamp.

[Action]

In this invention, white light is emitted toward the room and ultraviolet light is emitted toward the opposite room.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment thereof.

1 and 2 show an embodiment of an air sterilizer according to the present invention. As shown in these figures, this air sterilizer is equipped with a suspension pipe 2 from the ceiling portion 1,
Mounted on 2 and suspended. The device comprises a case 3, which has an upper opening 4 at its upper end.
However, lower openings 5 are formed at the lower ends, and the slanted wall serves as a reflecting portion 6. Ballasts 7, 7 are arranged at both ends of the case 3 in the longitudinal direction, and a sterilization lamp 8 at the center is provided inside the case 3.
Two complementary color lamps 9 and 10 having a complementary color relationship are arranged on this. The sterilization lamp 8 is supposed to emit 253.7 nm ultraviolet light and also blue visible light. Among the complementary color lamps, one that emits red light and the other 10 that emits green light are used. A panel 11 made of opalescent glass is provided on the entire surface of the lower opening 5 and is secured by mounting pieces 12, 12. This panel 11 is a panel for radiating while diffusing white light obtained by mixing visible light from the sterilizing lamp 8 and light from the complementary color lamps 9 and 10 while blocking ultraviolet rays emitted from the sterilizing lamp 8. ing.

Ultraviolet rays from a sterilization lamp 8 are radiated from the upper opening 4 toward the opposite side of the room, effectively sterilizing the indoor air that naturally convects while sterilizing the entire room air. White light passing through the panel 11 is emitted indoors. The light from the lamp 8 is effectively mixed with this white light.

As described above, in the air sterilization apparatus according to the present invention, the sterilization apparatus and the lighting apparatus are integrated and integrated as one apparatus, so that the ceiling portion is not complicated and the installation work can be performed collectively. It is possible and advantageous. Since the room side is illuminated with white light, the natural color of tableware and the like is not impaired, and the sterilizing lamp also functions for illumination, thus saving energy.

In the air sterilizer, the switch circuit can be configured so that only the sterilization lamp is turned on at night. In the above-mentioned embodiment, the panel is fixed, but as shown in FIG. 3, the panel 11 can be opened and closed by supporting the panel 11 with a hinge 15 and detachable with a latch 16. it can. In this case, by opening the panel 11 at night, the indoor air below can be directly sterilized in a wide range. The case may be provided with a transparent plate surface instead of the upper opening. The panel may be integral with the case.

[Effect of device]

Since the air sterilizer according to the present invention is configured as described above, the complexity of the ceiling part is eliminated, the installation work is simplified, and the natural color of food and dishes is maintained. Not only will it not be damaged, but it will also contribute to energy conservation.

Claims (1)

[Scope of utility model registration request] 1. A case is provided, wherein at least a surface to be directed to the indoor side is a surface that cuts ultraviolet rays and transmits visible light, and a surface that is directed to the opposite indoor side is a surface that transmits ultraviolet rays. An air sterilizer in which a sterilizing lamp and a complementary color lamp that emits light having a complementary color relationship to visible light emitted from the lamp are provided in the same case.
