Abstract

The water closet has a drainage port in a position higher than the floor. During a flushing operation, an air vent space is partitioned by a water wall formed by a water flux dropping from a dam and by an increase of the water level in a reservoir. The air in a trap is pushed out speedily toward the drainage port, due to the rapid flow of water to make vacuous the interior of a trap's drainage passage, and make it ready to start a siphoning action. When the feeding of water from a tank has been completed, so that the continuous siphoning action approaches the end, a notch is formed in the water wall. This notch permits the air to enter the air vent space immediately.

Detailed description of the invention

[Industrial use]

The present invention relates to a flush toilet having a drainage hole above the floor.

[Prior art]

One-piece toilets of low silhouette type are known in the art (for example, see Japanese Patent Application Laid-Open No. 61-106584).

By the way, this type of flush toilet is combined with the toilet body as much as possible to have the height direction dimension of the washing water tank to have a sense of unity. For this reason, a sufficient water head cannot be taken, and the instantaneous flow rate of the water supply, which is a large factor that determines the toilet's cleaning function, is a type of toilet in which a washing water tank is installed on the toilet body, and a flash valve It is significantly lower than the toilet of the type using.

In general, the wall drainage type toilet has a central height of 100-150 mm from the floor surface for the construction and the function of the toilet. However, the one-piece toilet of the low-silhouette type is the wall drainage type. In order to secure the height of the drain, there is no drop from the water surface of the bowl to the center of the drain, and it cannot be satisfactorily overlapped with the above water supply conditions. Therefore, the one-piece toilet of the wall drainage type does not exist. .

On the other hand, since one-piece flush toilets are treated as high-end toilets, the installation of one-piece toilets is highly desired in luxury manshons, luxury hotels, and suites.

However, in hotels and mansions, the ceiling beams often interfere with the drainage piping, and in the case of high-rise buildings, it is often necessary to remove the piping space in the ceiling to secure a space in the height direction. Therefore, in the conventional one-piece flush toilets in which drainage pipes must be disposed below the floor, there have been many cases in which the above market demands cannot be met.

[Problem trying to solve the invention]

The problem to be solved by the present invention is to enable a wall drainage in a one-piece flush toilet by using a novel structure in which a siphon is easily generated in the trap drainage passage and a strong siphoning force is obtained. .

[Means to solve the problem]

In order to solve the above problems, the technical means of the present invention is to establish a drain on the side circumferential surface of the trap drainage passage formed continuously in the bowl portion of the toilet body, the trap drainage channel downstream At the same time, the diameter of the trap drainage path is partially narrowed between the bank part and the water flow part, and the upper wall of the water flow part has a slight ventilation space between the storm water surface and the superior surface of the water flow part. It installs by hanging the partition wall and leaving a notch in the partition wall.

[Action]

In addition, according to the above technical means of the present invention, the aeration space is intercepted in a wall state by the rise of the water level falling from the bank and the water flow portion during washing, and the air inside the trap is quickly moved to the drain hole by the force of water. It is extruded and the trap drainage path becomes negative pressure. Therefore, the siphon is easy to cool.

In addition, the air is rapidly introduced from the notch of the partition wall at the time when the water supply from the tank is finished and the duration of the siphon is completed, so the timing of air introduction is accelerated, and the siphon is rapidly cut off.

EXAMPLE

EMBODIMENT OF THE INVENTION Hereinafter, one Example of this invention is described based on drawing.

(A) in the figure, (B) is a washing water tank integrally formed in the upper part of the rear, this washing water tank (B) is combined with the edge main body (A) by combining the height direction dimension with the edge main body as possible It is formed to have a sense of unity. The toilet body (A) is cleaned by the water supply chamber (10) installed at the rear of the bowl water (1) by a rim water passage (9) installed along the upper edge of the bowl part (1). The discharge port 11 opened in the middle of the height direction of the water tank B and at the bottom side surface of the bowl 1 is cleaned through a channel 12 provided outside the bowl 1. A part of the water tank B is in contact with each other, and the washing water in the tank B is partially along the wall of the bowl 1 from the water hole 13 formed in the lower surface of the rim channel 9. Water is supplied, and the remaining half is supplied from the discharge port 11 to the bottom of the bowl 1 in a swirling manner.

Moreover, the trap drainage path 2 which discharges the washing water supplied to the said bowl part 1 out of a toilet with dirt is provided in the toilet body A in communication with the bowl part 1, and is provided. The trap drainage path 2 opens the inlet 14 at the bottom of the bowl 1, and opens the outlet, that is, the drainage port 3 at the bottom of the toilet body A, at the lower end of the washing water tank B. It is formed in a substantially S-shape which is opened at an approximately intermediate position between the lower end of the valve body A and communicates between both of the entrances and exits 14 and 3.

That is, the trap drainage path 2 is a part (hereinafter referred to as part (a)) extending obliquely upward from the inlet 14 opened at the bottom of the bowl part 1 toward the rear of the toilet body A. (a) a portion extending continuously downward substantially vertically to the top of the portion and reaching from the height position of the inlet 14 and the drain port 3 to the downward position (hereinafter referred to as part (b)), and (b) It consists of a part (hereinafter referred to as part (c)) extending obliquely upward toward the drain port 3 in succession to the part, and forms the weir part 4 by the bottom wall of the upper part of the above-mentioned part (a). . In addition, the trap drainage passage 2 gradually reduces the diameter of the (b) portion downward to partially narrow the diameter of the drainage passage and forms the water flow portion 5 from (b) the lower portion of the portion to the middle portion of the (c) portion. .

In addition, the trap drainage path 2 has a partition wall 7 extending downward in the upper wall of the water flow section 5 and the upper wall, specifically, the boundary between the (b) and (c) sections. And a little ventilation space 6 is left between the water flow surface and the flow surface of the water flow part 5.

The partition wall 7 is provided with a notch 8 having a suitable width from the lower end to the middle in the height direction.

In addition, in order to generate a siphon, it is most suitable for the ventilation space 6 mentioned above to have dimensions about 20 mm.

In addition, although the above embodiment demonstrated the toilet of the low silhouette type, it may be a siphon and a siphon jet toilet, for example.

[effect]

The present invention has the following advantages because the configuration as described above.

(1) When cleaning, the air flow inside the trap is formed into a partitioned structure by wall formation due to the water dropping from the bank and the water level rise. Therefore, the air inside the trap is quickly extruded toward the drain by the force of water, and the trap pressure In this way, the siphon action can be easily generated.

Therefore, the flow rate of the water supply moment is significantly lower than that of a tank tight type toilet or a toilet using a flash valve, and furthermore, the wall drainage type ensures that the center height of the drain hole is about 100 mm from the bottom surface. The low-silhouette type one-piece toilet, which has a small drop from the water surface to the center of the drain, can provide a waste discharge function that can be sufficiently satisfied as a wall drainage type.

As a result, ceiling beams often obstruct the underfloor piping and often omit the piping space on the ceiling, and the high-rise buildings, luxury mansions, luxury hotels, etc. where the one-piece toilet of low-silhouette type was conventionally difficult to install. Installation is possible without any problems, and can respond to the market demand.

(2) By installing a notch in the partition wall, air can be introduced into the trap from the notch by the time the water supply from the washing water tank ends and the siphon duration ends, so that the siphon is terminated rapidly and the bowl surface water level surface In addition, the seal depth for the trap seal can be restored to its original state.

In this connection, if the notch is not provided in the partition wall, the siphon end time is remarkably long due to the rise of the water level in the water flow part and the falling water from the weir, making it difficult to secure the seal depth.

In addition, the above-mentioned notch does not have any influence on the siphon start time and the siphon strength since water film is formed by the water from the weir at the start of the siphon.

Claims (2)
