Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a Japanese-style toilet bowl. More specifically, the present invention relates to an improvement in the deodorizing structure of a Japanese-style toilet bowl.

[Prior Art] Conventionally, as a Japanese-style toilet, for example,
The one described in Publication No. 52 is known.

This conventional Japanese-style toilet has a deodorizing path that extends from the ball section to the front section adjacent to the rim passageway for flush water, and a slit-shaped intake port that faces into the ball section on the lower surface of the deodorizing path. An exhaust pipe equipped with an odor removal fan is connected to the deodorization path.

According to this conventional Japanese-style toilet, the odor of filth that has fallen into the bowl is sucked in through the intake port by the suction power of the deodorizing fan, and is further discharged outdoors from the exhaust pipe via the deodorizing path. It will be done.

[Problems to be solved by the invention] In the conventional Japanese-style toilet mentioned above, the toilet gets clogged.
Problems arise when dirty water accumulates up to the upper side of the rim of the ball portion, or when a large amount of water is sucked into the deodorizing path from the air intake port due to cleaning or the like.

That is, in the case of a m-shaped toilet such as the above-mentioned conventional Soshi-dai toilet, the inhalation Jilffi for effective deodorization is 0.2 to 0.
It is necessary to suction at a rate of 4Trl/min, but the sewage that is sucked in from the intake port and enters the deodorizing path is drawn near the rising base of the deodorizing path due to the negative pressure in the path, and accumulates so as to block the deodorizing path. , which significantly impairs the deodorizing effect and generates abnormal noise due to air replacement.

In addition, by stopping the deodorizing fan, the waste water that has accumulated in the deodorizing path will flow back into the bowl from the intake port, but if the toilet is clogged and floating filth, toilet paper, etc. once enter the deodorizing path. , it is not returned into the ball part by natural backflow. Therefore, such filth remains in the deodorizing path, which not only significantly reduces the deodorizing effect, but also eventually blocks the deodorizing path by repeating the entry of such filth several times.

The present invention was made in order to solve these problems, and its purpose is to provide a Japanese-style toilet bowl that can easily drain the washing water and filth that have entered the odor intake passage. be.

Another object of the present invention is to ensure the exhaust air in the Japanese-style toilet bowl, and to increase the degree of freedom in the exhaust direction.

Means for Solving the Problems J In order to achieve the above object, the Japanese-style toilet of the present invention has a small hole that connects the deodorizing path and the rim passageway, and a water bag portion between the rim passageway and the rim passageway. A number of communicating holes are provided at the base of the rising part of the front part.

It is preferable that the passage area of the above-mentioned dewatering channel is narrowed behind the intake port.

It is also convenient to open the exhaust ports for the dewatering channel on both the left and right sides of the front section.

[Function] According to the Japanese-style toilet configured in this way, the sewage that enters the deodorizing passage and is drawn near the base of the deodorizing passage due to the negative pressure in the passage passes through the small hole opened there. The water passes through the rim passageway and enters the water bag portion, and is discharged to the ball portion via the injection hole of the rim passageway and the spout of the cleaning water supply passage extending from the water bag portion.

In addition, dirt that has entered the deodorizing path enters the rim passageway from the water bag through the through hole during cleaning, and is further reversed against the air flow by the water flow and water pressure of the cleaning water that is ejected into the deodorizing path through the small hole. It will flow down into the ball part from the intake port.

On the other hand, the odor sucked into the deodorizing passage from the intake port flows forward through the deodorizing passage toward the exhaust port without passing around behind the intake port where the passage area is narrowed and flowing to the deodorizing passage on the opposite side.

Also, one of the exhaust ports opened on both the left and right sides is used depending on the situation at the construction site, and the other is closed.

[Example] Hereinafter, an example of a Japanese-style toilet bowl according to the present invention will be described based on the drawings.

The toilet bowl body (A>) consists of a front part (1) installed at the front to prevent urine from scattering, a ball part (2) installed at the rear to catch falling feces, toilet paper, etc. ) and a trap part (3) provided below the front part (1) continuously with the trap part (3), and a trap part (3) formed continuously with the trap part (3) and located below it through the bottom of the ball part (2). wash water.

It consists of a discharge port (4) for filth, etc., and a ball part (2).
) Along the periphery, a discharge wash water passage (5) constituting a wash water supply system for discharging dirt and a wash water rim passageway (6) constituting a wash water supply system for cleaning the ball wall surface were formed. It has a general basic structure.

The discharge washing water passage (5) is connected from a water supply chamber (7) installed in the front part (1) to which a water supply pipe (not shown) is connected, to a water bag part (8) connected to the water supply chamber (7). ) through the ball part (2)
along the periphery of the ball part (2) to the rear end of the ball part (2)
The left and right sides communicate with each other at the rear end, and a relatively large aperture-shaped spout (9) is provided at the core.

The rim water passageway (6) is formed above and adjacent to the discharge washing water passageway (5) and along the passageway (5), and the water passageway (6) is formed through the throughhole (10) at the base of the rising portion of the front part (1). It communicates with the bag part (8) and also communicates with the flushing water passage (5) at regular intervals in the length direction of the water passage (6) through several communication holes (11).

In addition, the rim passageway (6) has an injection hole (12) consisting of a large number of slit-shaped small holes along its inner periphery.
).

In addition to this basic structure, a deodorizing passage (13) is formed in this toilet bowl body (A).

The deodorizing passage (13) is formed adjacent to the upper part of the rim passageway (6) from the front part (1) of the toilet bowl body (A>) to the periphery of the ball part (2), and has a ball part on its inner peripheral surface. The intake port (2) is located toward the rear and has a relatively large opening shape.
14) are opened in pairs on the left and right facing the inside of the ball part (2).

In addition, the deodorizing passage (13) narrows the passage area behind the air intake (14) through a step (15), and exhaust ports (16) (16') are provided on both left and right sides above the front part (1). )
will be established.

The deodorizing passage (13) also communicates with the rim water passage (6) through a small hole (17) at the base of the rise of the front part (1).

Incidentally, during construction, the two exhaust ports (16) (16') may be connected to an exhaust pipe (18) equipped with an odor fan, etc. (not shown) to one of them, depending on the situation at the construction site. Close the other side with a blind cover (19).

Therefore, if the exhaust pipe comes within the operating range of the cleaning lever of the water supply fitting (e.g. flush valve),
Just connect the exhaust pipe to the exhaust port in the opposite direction.

In such a Japanese-style toilet, the air inside the bowl part (2) is drawn into the air intake port (14) by the suction of the odor evacuation fan provided in the exhaust pipe (18).
The odor is sucked into the deodorizing path (13) and discharged outside the building via the exhaust port ((16) or (16')) and the exhaust pipe (18).

At that time, the sewage that has entered the deodorizing path (13) from the air intake port (14) is moved to the rising edge of the deodorizing path (13) due to the negative pressure inside the path due to the suction of the deodorizing fan. However, since a small hole is drilled in this rising part, the wastewater in the deodorizing path (13) flows from the small hole (17) to the rim waterway (6), as shown in Figure 4. The - part is discharged from the injection hole (12) to the ball part (2), and the other part is discharged from the through hole (10) of the rim passageway (6) to the water bag part (8). Further, the cleaning water is discharged from the spout (9) to the ball portion (2) via the discharge cleaning water supply path (5).

In addition, the filth (C) that entered the deodorizing path (13) through the intake port (14) along with the sewage is left behind in the deodorizing path (13) when the sewage is discharged as described above, but when the cleaning lever is operated. When the washing water is flushed, a part of the washing water supplied to the water bag (8) is squirted into the rim passageway (6) through the through hole (10), as shown in FIG. It is also ejected into the deodorizing path (13) through the small hole (17), and the dirt (C) that has entered into the deodorizing path (13) is swept away toward the intake port (14), as shown in Figure 6. Effective discharge from the mouth (14) to the ball part (2).

In order to ensure the circulation of washing water through the through hole (io) and the small hole (17), and also not to obstruct the suction from the intake port (14), the intake air volume is set to, for example, 0.2 to 0.4 hours. /mi
If n, the intake port (14) and the through hole (10).

The opening ratio of the small hole (17) is 10 (400 m2): 3
(120al12): It is suitable to set it to about 3 (12011IR2).

Most of the remaining washing water supplied to the water bag section (8) described above flows into the discharge washing water passage (5) and is ejected from the spout (9) into the ball section (2) to form the ball. The filth in the part (2) is washed away to the trap part (3), and a part of it also flows into the rim water passage (6) from the discharge wash water passage (5) via the communication hole (11), and flows into the injection hole ( 12) to the ball part (2
) and wash the bowl wall.

In the above embodiment, exhaust ports are provided in both left and right directions of the front part, but the exhaust ports may be formed by opening holes in required directions during molding, for example.

[Effects of the Invention] As described above, the Japanese-style toilet according to the present invention allows the wastewater that has entered the deodorizing path and been drawn to the vicinity of the riser to be passed through the rim passageway through the small hole formed there. Since the deodorizing passage is quickly discharged to the ball side, the deodorizing passage is not blocked by the filthy water that accumulates near the base of the deodorizing passage and the deodorizing effect is inhibited, and the accumulated filthy water is replaced with air, causing abnormal noise. Nor.

In addition, even if the toilet bowl becomes clogged and dirt gets into the deodorizing path, some of the washing water supplied to the water bag during flushing will flow into the deodorizing path through the through holes and small holes. The dirt that has entered the deodorizing path can be washed away and effectively discharged from the intake port to the ball part, and there is no fear that the deodorizing path will be clogged by the dirt that has entered.

Furthermore, regardless of the presence or absence of dirt in the deodorizing passage, the inside of the deodorizing passage is cleaned every time the washing water is flushed after defecation, so the inside of the deodorizing passage is always kept clean and sanitary, and deodorization is carried out effectively. It has the effect of

In addition, the passage area of the deodorizing passage is narrowed behind the intake port, and this narrowed part acts as a flow path resistance, so the odor sucked into the deodorization passage from the intake port flows forward without resistance and is reliably discharged from the exhaust port. be done.

Furthermore, since the exhaust ports are installed on the left and right sides of the front part1, the exhaust pipe can be taken out in either direction depending on the construction site conditions, making it highly adaptable to the construction site. Installation is easy because the flush valve lever for flushing water supply does not get in the way when removing the cylinder.
