DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a siphon jet western style toilet, and more particularly to a siphon jet western style toilet with an improved structure for installing an air vent hole from a jet channel.

[0002]

2. Description of the Related Art As one type of Western-style toilet, there is a siphon-jet type Western-style toilet configured to squirt water into a trap portion to forcibly cause a siphon effect to enhance drainage from a toilet bowl. An example of a conventional example of this kind of siphon jet Western style toilet will be described with reference to FIG.

[0003] A trap portion 14 is provided below the toilet bowl 12 of the Western style toilet 10, and the trap portion 14 communicates with a drain port 18 via a drain passage 16. A rim water passage 20 is provided at an upper portion of the toilet bowl 12, and flush water is supplied to the rim water passage 20 through a water supply inlet 22 and a water supply passage 24.

[0004] The required ratio of the washing water is determined by the water outlet 26.
From the toilet bowl 12 and the rest of the water is
8, is supplied to the jet hole 30 facing the trap portion 14, and is ejected toward the trap portion 14. By jetting water from the jet hole 30 toward the trap portion 14 in this manner, a water flow from the trap portion 14 toward the drainage channel 16 is forcibly created, and siphons are caused at an early stage. Can enhance the exhaust power.

By the way, water is accumulated in the toilet bowl 12 to the same level as the top 16 a of the drainage channel 16. Water also accumulates in the Z waterway 28 so as to be at the same level as that in the toilet bowl 12, and air enters the upper part of the Z waterway 28.

When water is introduced into the rim water passage 20, and the water flows into the Z water passage 28, the air accumulated in the Z water passage 28 flows out from the Z hole 30 to generate a loud noise or a siphon effect. May be weakened.
Therefore, the upper part of the Z waterway 28 is communicated with the toilet bowl 12, and an air vent hole for extracting air remaining in the upper part of the Z waterway 28 is provided.

FIG. 5 is a cross-sectional view showing a structure in which an air vent hole 32 is provided on the side of the jet water channel 28. FIG. 6 is a cross-sectional perspective view taken along line 6-6 in FIG. When the air vent hole 32 is provided toward the inside of the toilet bowl 12 as described above, when the air in the jet channel 28 flows out from the air vent hole 32,
A part of the water that has flowed into the jet channel 28 may squirt out of the air vent hole 32 into the toilet bowl 12 together with the air, and the buttocks of the toilet user may be sprayed with water.

Therefore, in practice, as shown in FIGS. 7 and 8, a cover 34 is provided integrally with the toilet in front of the air vent hole 32. This cover 34 is used to manufacture a ceramic toilet bowl at a stage before firing.
It is formed by laminating a clay platelet-shaped compact on the inner surface of the toilet bowl 12.

[0009]

The conventional cover 34 described above.
The cover 3
4 had to be attached, and the production was troublesome. Further, there is a possibility that the back side of the cover 34 may be blocked, and it is necessary to clean a narrow space on the back side of the cover 34, and it takes time and effort for maintenance management.

[0010]

SUMMARY OF THE INVENTION The western style urinal of the siphon jet according to the present invention is characterized in that a part of the pot surface of the toilet bowl facing the Z waterway protrudes outward from the toilet bowl so that the toilet bowl has a toilet bowl. A step having a step surface extending substantially in the front-rear direction and substantially in the up-down direction is formed, and an air vent hole from the jet channel is provided in the step surface.

[0011]

[Action] In the siphon jet Western style toilet of the present invention,
Even if some water squirts along with air when air is extracted from the Z waterway into the toilet bowl, this water will squirt in the direction toward the side of the toilet bowl and will not reach the buttocks of the toilet user .

[0012]

Embodiments will be described below with reference to the drawings. FIG. 1 is a cross-sectional perspective view of a main part of a siphon jet western-style toilet according to an embodiment of the present invention, and FIG. 2 is a cross-sectional perspective view along line 2-2 in FIG.

In the present embodiment, a part of the bowl wall 36 of the toilet bowl facing the zet waterway 28 is protruded outward from the toilet bowl 12, so that the bowl wall 36 is substantially in the front-rear direction of the Western-style toilet bowl. A step surface 38 extending substantially in the vertical direction is formed.
8 has an air vent hole 40.

In the siphon jet western style toilet constructed as described above, even if a part of the water flows out of the air vent hole 40 together with the air when the air is extracted from the jet channel 28, the direction of the flow of the water is as follows. The direction is toward the side of the toilet 10. Therefore, the effluent from the air vent hole 40 does not reach the buttocks of the user of the Western-style toilet bowl at all.

Of course, this air vent hole installation structure does not require a conventional cover, which facilitates the manufacture of a siphonette Western-style toilet bowl, does not cause blockage in the space behind the cover, and facilitates cleaning. is there. In addition, since the water flowing out of the air vent hole 40 hits the pot surface 12a, the outflow water is also used as washing water for the pot surface 12a.

In the embodiment shown in FIG. 1 and FIG.
Although the reference numeral 8 extends vertically in the vertical direction, in the present invention, the cut surface 38 is shortened to the minimum necessary for providing the air vent hole 40 as shown in FIG. According to the embodiment shown in FIG. 9, the same operation and effect as the above embodiment can be obtained.

In the above embodiment, the jet channel 28 is connected to the toilet bowl 1
2, the present invention can be applied to a case in which the water channel is provided on the rear side of the toilet bowl.

[0018]

As described above, according to the siphon jet western style toilet of the present invention, even if water gushes from the air vent hole of the z waterway, this water only flows along the bowl surface of the toilet bowl. It does not touch the buttocks of the elderly. Further, the effluent from the air vent hole is effectively used as washing water for the toilet bowl surface.

The siphonette western-style toilet of the present invention is easy to manufacture and easy to clean.
