CONSTITUTION:An air suction port 4 is provided at a position faced to the retention water in a toilet stool, and a water film forming nozzle 9 forming a water film to surround part or the whole of the retention water in the toilet stool is provided around the air suction port 4. Activated carbon 3 is provided in an air duct 1 connecting the suction port 4 and a fan 2. The water film is formed to nearly surround the retention water surface, the air containing the odor in it is effectively sucked without being diffused to the surrounding, and it is fed through the activated carbon 3 for deodorization. An aromatic agent and a detergent can be mixed into water to keep the comfortable using feeling and cleanliness.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for deodorizing odor during defecation.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional deodorizing device is provided with an air blower 2 and a deodorizing agent 3 such as activated carbon in an air passage 1 so that a suction port 4 faces a distilled water 6 of a toilet bowl 5. Has been done.

The deodorizing device sucks in air containing a bad odor generated in the toilet bowl 5 at the time of defecation and passes the deodorant 3 to deodorize.

[0004]

However, in the above-mentioned conventional configuration, since the periphery of the stool is open, the air containing the odor cannot be effectively brought into contact with the deodorant 3 unless the amount of the intake air is increased. .. Therefore, there is a problem that noise increases as the air volume increases, and the air passage 1 and the blower 2 must be enlarged in relation to the pressure loss.

The present invention has been made to solve the above problems, and an object of the present invention is to realize a deodorizing device having a high deodorizing ability which can reliably collect air containing odor even with a small air volume.

[0006]

In order to achieve the above object, the present invention provides an air suction port provided at a position in the toilet facing the distillate water, and an air suction port provided around the air suction port. A water film forming nozzle that forms a water film so as to surround a part or the whole of the distilled water, a water supply unit that supplies water to the water film forming nozzle, a blower that sucks air from the air suction port, and An air passage that connects the air suction port and the blower and a deodorizing means installed in the air passage are provided.

As another configuration, the water supply means has an aromatic agent addition means and a detergent addition means for mixing an aromatic agent or a detergent into water.

[0008]

With the above-described structure, the present invention effectively absorbs the air in the toilet bowl containing odors by forming a water film so as to substantially surround the surface of the distillate and not diffusing the air into the surroundings. To deodorize. In addition, a fragrance is mixed with water forming a water film to add a scent desired by the user, or a cleaning liquid is mixed to clean the toilet bowl each time it is washed with water.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, a suction air passage 1 composed of a double pipe and a water passage 8 from a water pipe 7 serving as a water supply means are provided, and the tip of the suction passage 1 is located inside the toilet 5 from the rear of the toilet 5. The air inlet 4 and the water film forming nozzle 9 are formed so as to face the water 6. The water film forming nozzle 9 has a circular slit shape, and the discharged water forms a water film 10 so as to substantially surround the surface of the distilled water 6 in the toilet bowl 5. The blower 2 is connected to the suction air passage 1, and further the activated carbon 3 is provided in the suction air passage 1 as a deodorizing means.

In the above-mentioned structure, at the time of defecation, the water film 10 is formed from the rear of the toilet 5 by the water film forming nozzle 9 so as to almost surround the distilled water 6, and the waste water 6 and the surface of the distilled water 6 are falling. Shuts off the odor-laden air from the stool leaving
Avoid spreading the bad smell. On the other hand, the air containing the odor is sucked by the blower 2 from the air suction port 4,
It is deodorized by the activated carbon 3 provided in the suction air passage 1 and blown out of the toilet 5. At this time, since the space formed by the water film 10 and the surface of the distilled water 6 has a negative pressure, even if the water film 10 is somewhat incomplete, the odor is prevented from diffusing to the surroundings and is effectively sucked into the air suction port 4. ..

Therefore, the deodorizing apparatus of the present embodiment does not diffuse the odor, and the air containing the odor is surely activated by the activated carbon 3
Since it can be effectively deodorized by being sent to, a high deodorizing ability can be obtained, a sufficient deodorizing effect can be obtained even with a small air volume, and the blower 2 and the suction air passage 1 can be made small and noise can be significantly reduced.

Although not shown, as another embodiment, if a means for mixing the fragrance with the water forming the water film 10 is used, a pleasant scent with a desired scent can be obtained. Further, if a means for mixing the cleaning agent is adopted, the effect that the toilet bowl 5 can be kept clean each time it is used is obtained.

[0014]

As described above, the deodorizing device of the present invention forms a water film so as to almost surround the water surface and at the same time, removes air containing odor generated in the space formed by the water film and the water surface. Since it is sucked and guided to the deodorizing means, it is possible to effectively deodorize without spreading the odor to the surroundings. A sufficient deodorizing effect can be obtained even with a small amount of air, the size of the device can be reduced by reducing the air passage and the blower, and noise can be significantly reduced.

Further, if an aromatic agent or a cleaning agent is mixed in the water forming the water film, a more comfortable feeling can be obtained and the toilet bowl can be kept clean at all times.
