Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a blowout type Western-style toilet.

(Prior art) Conventionally, blowout type flush toilets have injection holes opened in the direction of the drainage channel at the bottom of the bowl surface, and sewage and filth on the bowl surface are discharged into the drainage channel by flushing water that is vigorously jetted from the injection holes. It is something that makes you At this time, since the pot surface is almost empty, the water ejected from the injection hole and the air caught in the water supply chamber are ejected together, producing an ejection sound, which becomes a noise that may harm not only the user but also other people. It also made me feel uncomfortable.

Publication of a utility model for reducing the above noise
There is a flush toilet disclosed in No. 56-17586. The structure of the conventional flush toilet bowl is shown in FIGS. 5 and 6.

As shown in FIGS. 5 and 6, the drainage channel 2 includes:
A first injection hole 4 is bored at the bent bottom so that cleaning water can be injected toward the discharge port 3, and further downstream there is a stepped portion on the back edge of the seat above the first injection hole 4. 5 is formed, and a second injection hole 6 is opened in the stepped portion 5 toward the discharge port 3 similarly to the first injection hole 4 described above. These first and second injection holes 4 and 6 are connected by the same water conduit 7 to a water supply port 8 drilled in the rear upper surface of the toilet main body A, and water is supplied to the water supply port 8 through a flush valve or a low tank. Washing water is first injected into the drain channel 2 from the second injection hole 6 and then from the first injection hole 4 toward the discharge port 3. or,
A communication hole 9 is bored in the side wall of the water conduit 7 above the water reservoir surface of the toilet main body A and at a position close to the reservoir water surface.

Reference numeral 10 denotes a rim water passage, which is formed in an annular shape along the upper edge of the bowl surface 1 of the toilet main body A, and a number of water injection holes 11, 11, . . . are bored at appropriate intervals on its lower surface.

Communication hole 9 between this rim passageway 10 and the side wall of the headrace channel 7
A second water conduit 12 is formed between the two to communicate with each other, and a part of the cleaning water supplied to the water supply port 8 is introduced into the rim water channel 10 through the communication hole 9 and the second water conduit 12. , water is ejected from the water injection holes 11, 11, . . . along the side surface of the pot surface 1 to wash the pot surface 1.

When cleaning water is supplied to the water supply port 8, most of the air accumulated on the water surface of the water conduit 7 is transferred from the communication hole 9 to the second water conduit 1 by the inflowing water.
2 and is discharged through the water injection hole 11 of the rim passageway 10, only a small amount of air that cannot escape from the communication hole 9 is drawn into the supply water, and this is also the air that cannot escape from the second injection hole 6. Almost no air is mixed in the water that is discharged together with the jet water and reaches the first jet hole 4, so that the water reaches the first jet hole 4.
The spraying of cleaning water from the sprayer is a spray of only water, and the spray noise can be made extremely small compared to spraying water that involves air.

(Problems to be Solved by the Invention) However, according to the above-mentioned conventional flush toilet, the rim water passage 10 is located near the water surface on the side wall of the water passage 7.
Since the communication hole 9 is drilled, air can be discharged as long as the communication hole 9 is in contact with the accumulated air, but since water is rapidly supplied from the water supply port 8, the air can be discharged. The contact between the communication hole 9 and the accumulated air ends before the injection is complete, and the remaining air is dispersed and gets caught up in the injection water to a large extent, which increases the noise during injection from the first injection hole 4 and reduces the injection water force. I had a problem with it becoming weaker.

Therefore, in the present invention, a communication hole with the rim passageway is drilled at a high position on the side wall of the injection water supply channel that communicates the water supply port and the injection hole, and the water supply port and the communication hole are located near the water surface. The technical problem to be solved is to reduce the amount of air mixed into the water jetted from the jetting holes by providing a partition wall that communicates only with the jetting holes.

(Means for solving the problem) The technical means for solving the above problem is to provide a Western-style toilet with a water supply chamber in the toilet body and an injection hole drilled to inject water into the drainage channel. A communication hole is drilled at a high position on the side wall of the injection water supply channel to be connected, and the rim water supply channel is connected to the injection water supply channel through this communication hole, and the water supply chamber and the communication hole are connected to the water supply channel near the reservoir surface. This is to provide a structure in which partition walls are provided that communicate only at positions.

(Function) According to the Western-style toilet with the above configuration, when flush water is supplied from the water supply chamber, the accumulated air in the supply chamber passes from between the lower end of the partition wall and the accumulated water surface to the rim water supply channel through the communication hole. Because of this, the amount of accumulated air that gets caught up in the cleaning water is extremely reduced, which has the effect of reducing the amount of air in the jetted water that is jetted from the jetting holes.

(Practical Example) Next, one embodiment of the present invention will be described with reference to the drawings.

The hole is opened so that cleaning water is sprayed in the direction.
On the downstream side of the drainage channel 21 from the injection hole 23, a stepped portion 31 is formed at a position below the injection hole 23, and an ejection hole 24 is opened in this stepped portion 31 toward the discharge port 22.

The injection hole 23 and the injection hole 24 communicate with the water supply chamber 26 of the toilet main body A via an injection water supply channel 32 provided along the bottom of the drainage channel 21 .

As shown in FIG. 2, the rim 27 is provided with a partition wall 33 whose lower end surface hangs down to near the reservoir water level, and the ceiling of the space between the side wall of the injection water supply channel 32 and the partition wall 33 is A communication hole 35 communicating with the water supply channel 28 of the rim 27 is drilled.

In the Western-style toilet configured as described above, when flush water is supplied from the water supply port 20 to the water supply chamber 26 via the flush valve or low tank, the air accumulated on the water surface of the water supply chamber 26 is removed from the flush water. The side wall of the injection water supply channel 32 and the partition wall 3
The rim 27 passes through the communication hole 35 through the air between the
from the water supply channel 28 through the fountain hole 29 toward the pot surface 25. At this time, the air accumulated in the water supply chamber 26 can be released to the water supply channel 28 of the rim 27 in a wide range of the lower end surface of the partition wall 33, so that the air is injected from the injection hole 23 through the injection water supply channel 32. There is less air mixed into the jetted water, which reduces noise during jetting.
At the same time, the ability to discharge water jetted from the jetting holes 23 is improved.

As described above, the cleaning water is ejected from the ejection hole 23 and from the ejection hole 24, and the washing water is ejected from the injection hole 24.
