Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a toilet bowl with a deodorizing function, and more particularly to a toilet bowl with a deodorizing function that deodorizes the toilet bowl by directly jetting a deodorizing agent into the toilet bowl body.

[Conventional technology] In recent years, the field of architecture has also changed due to social backgrounds.

They are becoming more intelligent and tend to be more upscale. People working in such buildings are also demanding greater comfort, and various improvements have been made to deodorize the toilets that people use every day.

Conventionally, such toilets have been deodorized by ventilation using a ventilation fan installed in the toilet, or by using a wall-mounted air freshener or spray deodorizer placed inside the toilet.

However, in such a deodorizing method, strong chemicals cannot be used in consideration of the effect on the human body, and there is a problem that the deodorizing effect is extremely small for strong odors associated with feces.

For this reason, traditionally, strong deodorizers were sprayed directly into the toilet bowl.
A toilet bowl with a deodorizing function that deodorizes while covering excrement in the toilet bowl has been developed.

A known example of such a toilet bowl with a deodorizing function is the one disclosed in Japanese Utility Model Application Publication No. 165367/1983.

This toilet with a deodorizing function has an automatic deodorizer sprayer placed in the center of the toilet lid, and when the toilet lid is closed, the automatic sprayer sprays deodorizer into the toilet bowl for a certain period of time. .

In addition, as other toilets with deodorizing function,
Some of these are disclosed in Japanese Patent Application Publication No. 8898 and Japanese Patent Application Laid-Open No. 1-97423.

This toilet bowl with a deodorizing function has a deodorant sprayer nozzle formed on the inner surface of the toilet bowl body, and a switch for operating the deodorizer sprayer is disposed between the toilet seat and the toilet bowl body.

Furthermore, as other toilets with deodorizing function,
There is one disclosed in Japanese Patent No.-156266.

This deodorizing toilet has a deodorizing sprayer that sprays deodorizing agent into the toilet bowl, which is activated by a manual switch installed outside.
Alternatively, it is activated by an infrared sensor that detects when a person enters the toilet room.

The toilet bowl with a deodorizing function configured as described above sprays a strong deodorizing agent directly into the toilet bowl, deodorizing it while covering the excrement in the toilet bowl, and deodorizing it inside the toilet bowl. It is possible to prevent bad odors from spreading outside the toilet bowl.

[Problems to be Solved by the Invention] However, the toilet bowl with a deodorizing function disclosed in Japanese Utility Model Application No. 63-165367 can disinfect the toilet seat and deodorize the interior of the toilet bowl, but it is possible to disinfect the toilet seat and deodorize the interior of the toilet bowl. Since the deodorizer is sprayed out when the lid is closed, it is impossible to eliminate the odor when it occurs, and there is a risk that the odor may fill the toilet room.

Also, Japanese Utility Model Publication No. 63-128898 and Japanese Unexamined Patent Publication No. 1998
In the toilet bowl with a deodorizing function disclosed in Publication No. -97423,
The problem is that the deodorant spray machine starts when a person sits on the toilet seat, so the deodorant spray machine starts working regardless of when a bad odor occurs, and as a result, a large amount of deodorant is required. was there.

Furthermore, in the toilet with a deodorizing function disclosed in Japanese Utility Model Publication No. 63-165367, when activated by a manual switch, the switch may be pressed even when there is no actual odor; The problem was that it did not suit the current trends. In addition, when activated by an infrared sensor, the deodorizer sprayer is activated when a person enters the toilet room, so the deodorizer sprayer is activated regardless of when a bad odor occurs. There was a problem in that a large amount of deodorant was required.

The present invention was made in order to solve the above-mentioned problems, and it provides a deodorizer that can reliably eliminate bad odors when they occur, and that can significantly reduce the amount of deodorant used than before. The purpose is to provide a toilet bowl with an odor function.

[Means to solve the problem]

The toilet bowl with a deodorizing function of the present invention has an odor sensor that detects bad odors arranged on the inner surface of the toilet bowl body, and a spout that spouts deodorant into the toilet bowl body for a certain period of time based on a signal from the odor sensor. It is formed by opening into the toilet main body.

[For production]

In the toilet bowl with a deodorizing function of the present invention, when a bad odor occurs inside the toilet bowl body, the smell sensor detects the foul odor, and the deodorizer is squirted from the spout into the toilet bowl body according to the signal from the smell sensor. .
