Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a deodorizing toilet that is equipped with an exhaust passage for odors generated during use of the toilet.

[Conventional technology]

3 and 4 show a conventional deodorizing toilet bowl 21 described in Japanese Utility Model Application Publication No. 60-80169, in which FIG. 3a is a partially cutaway plan view, and FIG. The side view, FIG. 4, is a sectional view taken along the - line in FIG. 3a. The deodorizing toilet bowl 21 has an exhaust passage 23 formed at the rear of the toilet bowl 22 for discharging odor inside the toilet bowl 22 to the outside of the toilet bowl. Odor intake port 24
As shown in FIG. 4, the toilet bowl 22 is provided by partially bulging the upper edge of the toilet bowl 22 outward and separating it from the rim passageway 25 to form an opening between the two. The exhaust port 26 is formed at the rear end of the toilet bowl 21, and is connected to an exhaust duct 28 that connects the exhaust port 26 to a fan 27. By driving the fan 27, the odor inside the toilet bowl 22 is removed by the arrow f.
The air is sucked into the intake port 24 along the direction of the air, and is discharged to the outside of the toilet bowl 21 through the exhaust passage 23 and the exhaust duct 28. Note that the exhaust passage 23 is shown in FIG. 3b.
As shown in FIG. 2, it is provided at the same height as the annular rim passageway 25 provided around the upper edge of the toilet bowl 22.

[Problem that the invention attempts to solve]

In the conventional deodorizing toilet bowl 21 described above, the intake port 2
4 is opened between the rim passageway 25 and the toilet bowl 22, so its opening area is small. Therefore,
The deodorizing ability was very low. Furthermore, since the suction speed is increased to ensure the required amount of ventilation, there is a risk that droplets of wash water, sewage, etc. will be sucked in as well. Furthermore, since the opening is narrow and the flow resistance is large, not only does intake noise occur, but the burden on the fan also increases.

Therefore, it is conceivable to increase the opening area of the intake port 24, but to do so, the opening must be expanded in the circumferential direction of the toilet bowl 22. However,
In order to prevent washing water droplets from being sucked in, the water injection hole 29 cannot be provided in the rim passageway 25 portion directly above the intake port 24. Therefore, the larger the opening area of the intake port 24 is, the more the area in the rim passageway 25 where the water injection hole 29 is not drilled increases, and as a result, the problem arises that the area of the toilet bowl 22 that cannot be washed increases. be.

[Means for solving problems]

The present invention solves and eliminates the above-mentioned problems, and aims to provide a deodorizing toilet bowl that has excellent deodorizing ability and has no or minimal unwashed area. The feature is that a rim is installed all around the upper part of the toilet bowl, and the rim has a water passage formed inside and a large number of water injection holes. In a toilet bowl in which a water supply chamber is provided behind the toilet bowl, one side wall of the water supply chamber extends straight to the inner wall surface of the rim, so that there is a single connection port from the water supply chamber to the rim passageway. Due to the limitation, the cleaning water flows in one direction through the rim water passage, and a rim end wall is formed on the outside of the water supply chamber, spaced from the water supply chamber wall and forming a terminal end of the rim water passage. An intake port facing the toilet bowl interior space is provided at the bottom of the rim portion partitioned by the rim end wall and the water supply chamber wall, and the intake port communicates with an exhaust port provided at the rear end of the toilet bowl. An exhaust passage is provided in the toilet bowl, and the bottom of the exhaust passage is formed into an inclined surface that rises from the intake port toward the exhaust port and has a scent.

[Effect]

In the deodorizing toilet according to the present invention, one side wall of the water supply chamber extends straight to the inner wall surface of the rim, so that the flush water supplied to the water supply chamber flows into the rim water passage through a limited communication port. Immediate influx. Therefore, since the washing water has a high flow rate, it can reach the end wall in a short time and fill the rim passageway with water. The intake port of the exhaust passage is provided at the bottom of the ventilation rim defined by the rim end wall and the water supply chamber wall. Therefore, since the width dimension where the rim overhangs the toilet bowl can be utilized, the opening area of the intake port can be increased. Moreover, since the width of the intake port in the circumferential direction of the toilet bowl does not become large, there is no or very small unwashed area. Moreover, since the intake port is opened in the rim, it is close to the location where the odor is generated. Furthermore, since the intake port opens downward, the structure is extremely difficult for splashes of washing water and sewage to enter.

In addition, since the bottom of the exhaust passage is formed into an inclined surface that slopes upward from the intake port to the exhaust port,
Even if splashes of wash water or sewage splash into the exhaust passage, they will not flow out of the toilet bowl.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 is a partially cutaway perspective view of the deodorizing toilet according to the present invention, Fig. 2 a is a plan sectional view of the deodorizing toilet according to the present invention, and Fig. 2 b is a partial sectional view taken along line B-B in Fig. a. It is. In the drawing, 1 is a toilet bowl, 2 is a toilet bowl, 3 is a rim provided all around the upper part of the toilet bowl 2,
4 is a rim passageway formed inside the rim 3, and 5 is a water injection hole through which washing water is sprayed into the toilet bowl 2.

As shown in the drawing, one side wall 7 of the water supply chamber 6 is extended straight to the rim inner wall surface, and the communication port 4a from the water supply chamber 6 to the rim passageway 4 is limited to only one place, so that cleaning water can be The distribution direction was set to be one direction. Further, a rim end wall 8 is provided at a position separated from the water supply chamber wall 7, and the rim end wall 8 forms the end portion of the rim passageway 4. The flushing water supplied to the water supply chamber 6 flows into the rim passageway 4 from the inflow portion 4a, flows in one direction while being injected into the toilet bowl from the water injection hole 5, collides with the rim end wall 8, and then flows into the rim water passageway 4. The water passageway 4 is filled with water.

An exhaust passage 9 that communicates the toilet bowl interior space S with the outside of the toilet bowl is provided in the toilet bowl interior space defined by the water supply chamber wall 7 and the rim end wall 8. The intake port 9a of the exhaust passage 9 connects a part of the rim 3 to the water supply chamber wall 7.
The ventilation rim 10 is provided at the bottom of the ventilation rim 10, which is partitioned by the rim end wall 8 and the rim end wall 8. Therefore, the structure is such that it is extremely difficult for splashes of washing water or sewage to enter into the intake port 9a. Further, since the intake port 9a is provided by utilizing the width dimension where the rim 3 overhangs from the toilet bowl opening edge 2a, a wide opening area can be secured without increasing the frontage dimension in the circumferential direction of the toilet bowl. I can do it.

Further, an exhaust port 9b is provided at the upper part of the rear end wall 11 of the toilet bowl 1, and an exhaust duct, a fan (not shown), or the like is connected to the exhaust port 9b to ventilate the space S in the toilet bowl. In addition, as shown in FIG. 2b,
The bottom 12 of the exhaust passage 9 is sloped upward from the intake port 9a to the exhaust port 9b, so that even if splashes of wash water or sewage enter, they will not flow out to the outside of the toilet bowl. I won't let you.

[Effect of idea]

As detailed above, the deodorizing toilet according to the present invention is
It has the following effects.

Since the opening area of the air inlet is large, the space inside the toilet bowl can be ventilated in a very short time, resulting in an excellent deodorizing effect.

Since the flow resistance of the intake port is low, there is less noise during suction, and the burden on ventilation fans, etc. is also reduced.

Since the width of the intake port in the circumferential direction of the toilet bowl does not become large, there is no or very small unwashed area.
Therefore, the interior of the toilet bowl is always kept sanitary.

Since the intake port is close to the location where the odor is generated, it is possible to suck the odor and eliminate it before it disperses. Therefore, high deodorizing efficiency can be obtained.

The intake port is located at the bottom of the rim, so
It is extremely difficult for splashes of wash water or sewage to enter the exhaust passage. Therefore, there is no risk of wetting or contaminating the inside of the exhaust passage or the exhaust duct, fan, etc. outside the toilet bowl.

The bottom of the exhaust passage is sloped upward from the intake port to the exhaust port, so even if splashes of wash water or sewage enter the exhaust passage, they will not flow to the outside of the toilet. It will not be leaked.

Since one side wall of the water supply chamber extends straight to the inner wall surface of the rim, the cleaning water supplied to the water supply chamber immediately flows into the rim passageway through a communication port that is limited to one location. Therefore, since the flow rate of the cleaning water is high, it can reach the end wall in a short time and fill the rim passageway with water. This has an extremely useful effect when the amount of washing water is small or when saving water.
