Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet deodorizing device, and more particularly to a toilet deodorizing device configured to discharge odor in a bowl to a downstream side of a trap portion.

[0002]

2. Description of the Related Art A toilet deodorizing apparatus of this kind includes an exhaust passage communicating with a downstream side of a trap portion in a bowl of the toilet and an exhaust fan provided in the exhaust passage. The exhaust passage is provided with a check valve which is normally closed when the exhaust fan is not operated. When the exhaust fan is operated, the odor in the bowl is discharged to a sewer or a septic tank via a drain pipe.

[0003]

In the above-mentioned conventional toilet deodorizing apparatus, there is a possibility that insects that have risen in the drain pipe may pass through the exhaust passage and reach the inside of the bowl when the check ring is opened.

[0004]

SUMMARY OF THE INVENTION A toilet deodorizing apparatus according to the present invention comprises an exhaust passage communicating between the bowl of the toilet and the downstream side of the trap portion, and an exhaust fan provided in the exhaust passage. In the apparatus, an insect repellent net is provided in the exhaust passage so as to cross the passage.

[0005]

According to the toilet deodorizing device of the present invention, insects that have risen in the drain pipe are prevented from moving to the exhaust passage upstream of the insect repellent net.

[0006]

FIG. 1 is a cross-sectional view of a Western-style toilet 1 equipped with a toilet deodorizing device according to an embodiment, and FIG. 2 is an enlarged view of a portion II in FIG.

A rim water passage 3 is provided on the upper edge of the toilet bowl 2 of the Western style toilet 1.
Is provided. The trap part 4 at the bottom of the toilet bowl 2 is connected to a drain pipe 7 via a drain socket 5. The deodorizing suction hole 8 at the upper part of the toilet bowl 2 is connected to a hose connection portion 13 of the drain socket 5 via an intake duct 9, an exhaust fan (deodorizing fan) 10, a check valve 11 and an exhaust hose 12. . An exhaust passage is constituted by the intake duct 9, the passage in the deodorizing fan 10, the passage in the check valve 11, the exhaust hose 12, and the hose connection portion 13.

In this embodiment, as shown in FIG. 2, an insect net 14 is provided in the hose connection portion 13 of the drain socket 5 so as to cross the passage.

The provision of the insect repelling net 14 prevents insects from entering the exhaust hose 12.

The above embodiment is an example of the present invention, and the insect repellent net may be provided at a location other than the above. For example,
It may be provided in the middle of the exhaust hose 12 or the like. However, as in the illustrated embodiment, it is preferable to install an insect repellent net as close as possible to the drain pipe.

In the above embodiment, the exhaust hose is connected to the drain socket. However, the present invention is also applicable to a case where the exhaust passage member such as the exhaust hose is directly connected to the toilet portion on the secondary side of the trap or the drain pipe. Clearly applicable.

Further, in the above embodiment, a Western-style toilet is shown as a toilet, but a Japanese-style toilet or a urinal may be used.

[0013]

As described above, according to the toilet bowl deodorizing device of the present invention, insects can be reliably prevented from entering the bowl.
ADVANTAGE OF THE INVENTION According to this invention, not only the insect which goes up the inner surface of a drainage pipe but the insect which has a flying ability can also be prevented from invading a bowl.
