JP2002355194A - Irradiation device for inside of toilet to accelerate photocatalytic reaction - Google Patents

Abstract

PROBLEM TO BE SOLVED: To keep the inside of a Western-style toilet in a sanitary condition all the time by attaching an irradiation device for the inside of the toilet to accelerate a photocatalytic reaction to the existing Western-style toilet. SOLUTION: Forming a photocatalytic layer 6 inside the Western-style toilet and cutting off a part of the center of a lid 1 of the Western-style toilet allow an attachment of a fluorescent lamp 5, which turns on and off when the lid 1 of the Western-style toilet closes and opens, and attachments of protecting covers 3, 4 in a manner that they face to the photocatalytic layer 6. As the fluorescent lamp 5 turns on when the lid 1 of the Western-style is closed, a photocatalytic reaction is accelerated inside the Western-style toilet, and the inside of the Western-style toilet is kept sanitary.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet irradiating device for irradiating light such as ultraviolet rays to the inside of a western toilet having a photocatalytic layer to promote a photocatalytic reaction, and to attaching the device to an existing western toilet. It is.

[0002]

2. Description of the Related Art Conventionally, a germicidal lamp is provided directly inside a Western-style toilet lid without using a photocatalyst to obtain a germicidal effect (for example, see Japanese Patent Application Laid-Open No. 10-304990). There is also a Western style toilet using a photocatalyst and ultraviolet rays (for example, see JP-A-9-78665 and JP-A-11-93241).

[0003]

Conventionally, a germicidal lamp was mounted inside the lid of a Western-style toilet bowl, and ultraviolet rays that harmed the human body were emitted from the germicidal lamp. There was a problem that it did not become.

[0004] Further, as a method of using a photocatalyst layer and combining it with ultraviolet light that has little effect on the human body, since it is incorporated in a Western style toilet lid and a Western style toilet body in a manufacturing process, it is attached to an existing Western style toilet lid. There was no problem.

[0005] The present invention provides a photocatalyst layer formed inside an existing Western-style toilet bowl, and a fluorescent lamp and a protective cover for irradiating ultraviolet light or the like with little effect on the human body can be attached to the western-style toilet bowl lid. It is another object of the present invention to provide a toilet interior irradiation device that promotes a photocatalytic reaction that is repeatedly turned off and turned on in response to opening and closing of a Western-style toilet lid.

[0006]

In order to achieve the above object, in the toilet irradiating apparatus of the present invention, a photocatalyst layer which is a crystal film of titanium oxide which promotes a photocatalytic reaction is formed inside an existing Western style toilet. Then, a part of the center of the lid of the Western style toilet is cut off, and a fluorescent lamp for irradiating light such as ultraviolet rays having little effect on the human body and a protective cover thereof are attached to the photocatalytic layer.

The fluorescent lamp and its protective cover are attached at the center of the Western-style toilet lid such that the protective cover does not touch the toilet seat with the existing Western-style toilet lid closed, and a part of the lid is cut off. It is effective to attach the moisture-proof protective cover and the upper protective cover so that it is sandwiched from both sides, and by inserting a fluorescent lamp into it, it has become possible to attach it to the existing Western toilet lid.

The switch is provided at the fulcrum of the existing toilet bowl lid, and turns off and on in response to the opening and closing of the toilet bowl lid. I will not do it.

[0009] Since the existing toilet bowl lid is lit when the lid is closed and the photocatalyst layer is irradiated with light such as ultraviolet rays, a strong oxidation-reduction action is generated inside the toilet bowl, so that it always occurs. You can keep it clean.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, the center of an existing one-sided toilet bowl lid is partially cut off, and five fluorescent lamps are inserted therein, and the three and four protective covers are fixed with eight screws.

In the embodiment shown in FIG. 2, a 6-photocatalyst layer is formed on the inside of an existing Western-style toilet, a center of the 1-Western-style toilet lid is partially cut out, and a 5-fluorescent lamp is put therein, and a 1-Western-style toilet is placed. The moisture-proof protective cover 3 and the upper protective cover 4 are fixed with eight screws so that the lid surface is sandwiched from both sides. The seven switch units are provided at the fulcrum of the Western-style toilet lid.

[0012]

Since the present invention is configured as described above, it has the following effects.

[0013] By partially cutting off the center of the Western-style toilet lid, it is possible to easily attach an interior toilet bowl irradiation device that promotes a photocatalytic reaction to an existing Western-style toilet lid.

Further, by providing the switch at the fulcrum of the Western-style toilet lid, it is possible to turn off and on the light according to the opening and closing of the Western-style toilet lid.

When the lid is open, the light does not turn off and is not exposed to a person. In addition, when the lid is closed, the light turns on when the lid is closed. , The photocatalytic reaction is promoted and functions effectively. Since the cleanliness can be maintained without bothering the human hands, the number of times of cleaning is greatly reduced.

Further, as long as the photocatalyst layer is present inside the Western style toilet, the fluorescent lamp for irradiating light such as ultraviolet rays can be used semipermanently only by periodically replacing the fluorescent lamp.
