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 device, there is a risk that insects that have climbed up 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 device 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 electric shock device for insects is provided in the exhaust passage.

[0005]

According to the toilet deodorizing device of the present invention, the insects climbing in the drainpipe are shocked by the electric shock device, so that the insects are prevented from moving further upstream.

[0006]

FIG. 1 is a cross-sectional view of a Western-style toilet 1 provided with a toilet deodorizing device according to an embodiment, FIG. 2 is an enlarged view of a portion II in FIG. 1, and FIG. 3 is a III-III in FIG. It is a line sectional view.

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 discharge part 5 and a drain port 6.
The deodorizing suction hole 8 at the upper part of the toilet bowl 2 is connected to the opening 13 of the drainage section 6 via an intake duct 9, a suction fan 10, a check valve 11 and an exhaust hose 12. 11a
Is a valve body of a check valve, 11b is a solenoid for bringing the valve body 11a into and out of contact with the seat portion 11c, and 11d is a link mechanism.

In this embodiment, a pair of opposing electrodes 14 and 15 are provided on the inner surface of the exhaust hose 12, and a high voltage can be applied to the electrodes 14 and 15 by a power supply device 16. I have.

Since the electric shock device 17 including the electrodes 14 and 15 and the power supply device 16 is provided, when insects enter the exhaust hose 12 and enter between the electrodes 14 and 15, Then, an electric discharge occurs, and the insects are shocked and killed, or the biological function is paralyzed so that the insects do not move to the upstream side, thereby preventing entry into the toilet bowl 2.

According to the present embodiment, not only insects climbing up the inner surface of the hose but also insects flying in the hose can be shocked, so that invasion into the toilet bowl can be reliably prevented.

In the embodiment shown in FIGS. 1 to 3, the plate-like electrodes 14 and 15 are opposed to each other on the inner surface of the hose. However, as shown in FIG. The electrode 31 may be provided on the inner surface of the hose, and a high voltage may be applied between the center electrode 30 and the counter electrode 31 to strike an insect that has entered between the electrodes 30 and 31.

FIG. 4 shows an electric shock device according to another embodiment, in which annular anodes 20 and cathodes 21 are provided alternately on the inner surface of a hose 12. Note that a narrow insulating band 22 is provided between the anode 20 and the cathode 21.
A low voltage is applied between the anode 20 and the cathode 21 by a power supply device.

When an insect comes up in the hose 12, when the body comes into contact with both the anode 20 and the cathode 21 across the insulating band 22, the insects short-circuit the poles 20 and 21, and 24 is shocked. This will kill the insects or paralyze biological functions and prevent further invasion.

In the embodiment shown in FIG. 4, the anode and the cathode are each annular, but they may be provided spirally on the inner surface of the hose.

In the above embodiment, the electric shock device is provided in the exhaust hose 12, but it may be provided in other places in the exhaust passage. However, in order to ensure that insects that have fallen in the hose due to the electric shock are directly dropped into the drain pipe, the electric shock device is provided near a drain passage (a drain portion or a drain pipe of a toilet bowl) and the electric shock device is installed. It is preferable to provide the exhaust passage so as to have a vertical or nearly downward slope from the portion toward the drain passage.

In the above embodiment, the exhaust hose is connected to the drainage part. However, it is apparent that the present invention can be applied to the case where the exhaust passage member such as the exhaust hose is connected to the drainage member such as the drain socket. .

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

[0018]

[Effects of the Invention] As described above, according to the toilet bowl deodorizing device of the present invention, insects can be reliably prevented from entering the bowl.
