Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a flush type toilet bowl, which is characterized in that sealing water is completely secured in a sealing water trap and is economical.

[Conventional technology]

In the flush type toilet bowl, a so-called sealing trap is configured in order to enhance the effect of discharging waste, and further to prevent odor from returning from the drain pipe side and prevent invasion of insects.

Conventionally, an S-shaped trap or the like has been generally adopted as the sealing water trap, and waste is discharged together with water by utilizing the siphon phenomenon (vacuum suction phenomenon).

[Problems to be solved by the device]

In the above-mentioned conventional toilet, due to various circumstances such as waste, water supply or drainage, the siphon phenomenon (vacuum suction phenomenon) acts more than necessary, the sealing water is sucked and discharged, and further air is sucked to generate gurgling noise and unpleasant noise. There were cases.

Moreover, the reduction of the sealing water resulted in the remission of odor and the invasion of insects from the drain pipe side.

The above phenomenon was particularly remarkable in a high-rise building where the horizontal drainage pipe (22), which will be described later, is long.

That is, since the wastewater and the water flow in the horizontal drainage pipe (22) in a state where the wastewater and the water are filled, the downstream side of the sealing water trap becomes a vacuum state and the water of the sealing water trap is sucked and discharged.

Therefore, loop ventilation pipes (23) were installed separately in high-rise buildings.

The details are shown in FIG.

In the same figure, (20) is a drainage stand vertically installed on each floor of the building, and (21) is a ventilation stand installed vertically on each floor of the building like the drainage stand (20). The pipe, (22) is a horizontal drain pipe provided on each floor of the building by branching from the drain pipe (20), and (23) is an appropriate position of the horizontal drain pipe (22) and the ventilation pipe (21). ) Is a loop vent pipe connecting the two, and (24) is a plurality of toilet bowls connected to the horizontal drainage pipe (22).

In the above structure, the hoop ventilation pipe (23) is provided with the toilet bowl (2
It acts to secure sealing water in 4).

That is, the loop ventilation pipe (23) allows the horizontal drain pipe (2
If the proper position of 2) is not open to the atmosphere, the water in the toilet bowl (24) will be sucked and discharged due to the siphon phenomenon of the drainage stack pipe (20) and the horizontal drainage pipe (22), and the sealing water cannot be secured. .

Therefore, in the current construction method, a loop ventilation pipe (23) is provided to prevent the suction and discharge of the sealing water.

As mentioned above, in high-rise buildings, etc., the ventilation stack pipe (22) and loop ventilation pipe (23) are provided to secure the water seal in the toilet (24), but the construction cost (material cost) for the installation , Personnel costs) are expensive and cannot be ignored.
It is an object of the present invention to provide a toilet bowl in which the loop vent pipe (23) and its construction are unnecessary and a predetermined amount of water is completely secured.

[Means for Solving the Problems]

In order to achieve the above object, the present invention has an upper end bent downward and an opening located below the surface of the tank water at the top of the drainage side of the water sealing trap, and the upper end is opened to the atmosphere when the tank water is discharged. A ventilation pipe is connected.

[Action]

The toilet bowl of the present invention has the same usage method as the conventional one.

That is, it is only necessary to operate the drain handle (10).

As a result, the tank water (6) in the water storage tank (2) is supplied into the main body (1) and the wastewater trap (3) is supplied together with the waste.
It is discharged through the siphon phenomenon (vacuum suction phenomenon).

When the tank water (6) in the water storage tank (2) decreases and the water surface (l) falls below the opening (9b) of the upper end (9a) of the ventilation pipe (9), the ventilation pipe (9) The tank is opened to the atmosphere through the vent hole (11) opened in the tank, the siphon phenomenon (vacuum suction phenomenon) is eliminated, and a predetermined amount of sealed water (4) is secured in the sealed water trap (3).

〔Example〕

An embodiment of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, (1) is the main body, (2) is the water storage tank,
(3) is a sealing water trap, (4) is sealing water, (5) is an existing overflow pipe, (6) is tank water, (7) is a valve seat,
(8) is a lid, and (10) is a water supply handle.

The above configuration is the same as the conventional one. In the present invention, a vent pipe (9) whose upper end (9a) is open to the atmosphere when the water is discharged from the water storage tank (2) is connected to the drain side top part (3a) of the sealed water trap (3).

That is, specifically, the ventilation pipe (9) is extended into the water storage tank (2), the upper end (9a) thereof is bent downward, and the opening (9b) is opened at the water surface (l) of the tank water (6). ) It is located below.

In the figure, (11) is a vent.

In addition, the opening time of the ventilation pipe (9) to the atmosphere is the upper end (9
It can be freely adjusted by the length of the bent part in a).

In the present invention having the above-mentioned configuration, waste and tank water are initially vacuum-sucked through the sealing trap due to the siphon phenomenon. The water will be secured.

[Effect of device]

According to the present invention, since a predetermined amount of water is always secured in the sealing water trap, it is possible to prevent the odor from returning from the drain pipe side and the invasion of insects and to prevent the generation of unpleasant noise. Especially when it is used in a high-rise building or the like, the loop ventilation pipe can be eliminated, and an extremely economical effect can be obtained.
