Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a siphon-type toilet bowl, and more particularly to a siphon-type toilet bowl that does not generate an unpleasant sound at the end of washing.

[0002]

2. Description of the Related Art Conventionally, in a siphon type toilet bowl, a partition is provided inside the toilet body to form a trap, and the water inside the trap seals the odor from the drain pipe side connected to the trap into the toilet space of the toilet body. I try to prevent it from rising. In the conventional siphon-type toilet bowl described above, at the time of cleaning, after a cleaning sound of "jare" continues for a certain period of time, a cleaning sound of "bumpy" is generated at the end.
This sound at the end of cleaning is generated as a result of the air being drawn from the toilet bowl through the sealing water of the trap when the cleaning water flows out of the trap. felt. Actual Kaisho 61-15383
The "flush-type toilet" disclosed in the publication does not generate the above-mentioned "bubbly, squeaky" washing noise at the end of washing, and thus is stored in the trap in the partition wall between the toilet space and the trap. A hole is provided at a position higher than the liquid level of the sealing water so that the air on the side of the excretion space is drawn in from this hole when the cleaning water flows away in the trap.

[0003]

In the conventional flush toilet bowl described above, a hole is formed in the partition between the toilet space of the toilet body and the trap at a position higher than the liquid level of the sealing water stored in the trap. Since this is provided, there is a problem that odors and insects enter through this hole. Therefore, in the present invention, it is an object to be solved to prevent generation of odors and insects, and to prevent generation of "buzz, buzz" cleaning noise at the end of cleaning.

[0004]

In a first invention for solving the above problems, in a siphon type toilet bowl, a hole is formed in which the opening surface is submerged between the trap water collecting surface of the toilet body and the lower end of the partition wall. Opening the end of the tube in communication with the hole above the top of the trap.

According to the second aspect of the invention, a hole whose opening surface is above the trap water surface of the toilet body is formed, and the pipe communicating with this hole is once bent downward so that sealing water can enter the pipe. To form a trap and open the other end of the conduit above the top of the trap.

[0006]

In the first aspect of the present invention, the hole in which the opening surface is submerged is formed between the trap water surface of the toilet body and the lower end of the partition wall, and the end of the pipe communicating with the hole is opened above the upper end of the trap. During cleaning, a jet flow is injected from the jet hole, the inside of the trap becomes a negative pressure state, the cleaning water is sucked into the trap, and the air from the opening of the pipe is sucked into the trap from the hole. The negative pressure inside is released, and the intake of air from the trap inlet is stopped. Therefore, in the conventional siphon-type toilet bowl, of course, there is no buzzing noise that is generated at the end of washing, and normally the holes are blocked with sealing water, which prevents odors and insects from entering. .

According to the second aspect of the invention, a hole whose opening surface is above the trap water surface of the toilet body is formed, and the conduit communicating with this hole is once bent downward to seal the water in the conduit. Since a small trap that enters is formed and the other end of the pipe line is opened above the upper end of the trap, a jet flow is jetted from the jet holes during cleaning, causing a negative pressure inside the trap, as in the first invention. The cleaning water is sucked into the trap and the air from the pipe opening is sucked into the trap from the hole, so the negative pressure inside the trap is released, and the suction of air from the trap inlet is eliminated, "Boko, at the end
Of course, there is no buzzing noise, and the holes are usually blocked with sealing water, so that odors and insects are prevented from entering.
