Abstract

PROBLEM TO BE SOLVED: To provide a toilet having a stronger pressing force to a trap and a larger draining capacity. SOLUTION: This toilet is of a type in which a water basin part 3 is formed from a bowl part 2 toward a rear side trap inlet 4a, and a main flow S1 of flushing water carried into the bowl part 2 is carried into the water basin part 3 over a center line C1 as eddy current. A passage groove 7 having a front end opening 7a opened just opposite to the flushing water main flow S1 and rear end inclined to the center line C1 communicating with the trap inlet 4a is formed on the bottom part of the water basin part 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet bowl with improved drainage capacity.

[0002]

2. Description of the Related Art Conventionally, in a toilet having a large reservoir surface, a siphon-type toilet has been employed in order to obtain sufficient drainage performance. However, there has been a problem that good drainage performance cannot be obtained except for the siphon type toilet. Note that the siphon-type toilet has another problem that a breakage sound is generated due to a siphon action at the time of drainage, and noise is generated.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a toilet bowl with a large drainage capacity. A water reservoir for storing water is formed toward the trap inlet on the side, and a main flow of the washing water flowing down into the bowl portion flows over the center line in a vortex to flow into the water reservoir portion, In the bottom surface of the reservoir, a front groove is formed to open frontward with respect to the main flow of the washing water, and a rear end is formed with a passage groove inclined to the center line communicating with the trap inlet.

[0004]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the toilet, and FIG.
It is a longitudinal section block diagram of a toilet. On the rear side of the bowl part 2 of the toilet bowl, a water storage part 3 for storing water one step lower is formed.
The rear end of the reservoir 3 communicates with the trap inlet 4a, and the trap 4 is formed so as to be inclined upward rearward. Further, a drain port 5 is formed at the rear end of the trap 4 in a hanging manner. A rim 6 is formed on the outer periphery of the upper surface of the bowl portion 2, and the inside of the rim 6 is a rim water passage 6 a through which washing water passes.

[0005] The washing water supplied from the low tank is shown in FIG.
As shown in (1), a large flow rate flows down from the rim water passage 6a on one side, and a small amount of washing water flows down from the rim water passage 6a on the other side. It is configured to swirl to the other side and flow into the pool 3 in the form of a vortex, so that a strong cleaning power is obtained by the vortex generated by the main flow S1. At the bottom side of the part 3, a front end opening 7a is opened in front of the main flow S1 of the washing water so as to be inclined with respect to the center line C1 in the front-rear direction in the plan view of FIG. Channel groove 7 is formed,
The main flow S1 of the washing water flows into the front end opening 7a of the passage groove 7 from the front, and the main flow S1 makes the reservoir 3 stronger.
The stored water W stored in the inside is pushed into the trap inlet 4a, and the wastewater or the like can be discharged strongly through the trap 4.

FIG. 3 is a sectional view taken along the line A--A in FIG.
The passage groove 7 formed on the bottom side of the reservoir 3 is formed by a left and right side wall surface 7 extending from the longitudinal center line C2.
The distances a and b to b are different from each other on the left and right, and are formed in an asymmetric shape with respect to the vertical center line C2.

The sectional view of FIG. 4 is taken along the line BB in FIG.
It shows a line cross section, and the asymmetric shape of the passage groove 7 is larger on the front end side on the pot portion 2 side, and the dimension of b is larger than that of a.

On the other hand, as shown in FIG. 5, which shows a cross section of the CC line in FIG. The main flow S1 forming the vortex flows reliably into the passage groove 7 while forming a vortex without receiving resistance from the bowl portion 2 side, and the swirling force of the vortex acts strongly on the trap inlet 4a, and Can push wastes into trap 4
The pushing force into the trap 4 is stronger than before, and therefore the drainage capacity is greater than before.

Therefore, in the toilet 1 having such a passage groove 7, a sufficient drainage capacity can be obtained, so that the toilet can be made without drainage by the siphon action and without noise by the siphon action. If a socket having a reduced diameter is connected to the drain port 5 so as to generate a siphon action, a stronger drainage capacity can be obtained. In addition, by forming such a passage groove 7, the amount of the stored water W stored in the stored water portion 3 can be made smaller than before, and a water saving effect can be obtained.

[0010]

According to the present invention, a reservoir is provided for retaining water from the bowl toward the trap inlet on the rear side, and the main flow of the washing water flowing into the bowl forms a vortex beyond the center line. In the toilet bowl of the type that flows into the reservoir, the front end of the bottom of the reservoir is open frontward with respect to the main flow of the wash water, and the rear end of the toilet with respect to the center line communicating with the trap inlet. By forming the inclined passage groove, the main flow of the swirling washing water flows down toward the trap inlet through the passage groove with the swirling force applied without resistance, so that the pushing force into the trap is And the drainage capacity can be improved more than before, and there is no need for drainage by the siphon action, which has an effect of obtaining good drainage performance.

Claims (1)

[Claims] 1. A reservoir for storing water is formed from a bowl toward a trap inlet on a rear side, and a main flow of washing water flowing down into the bowl is swirled beyond a center line to form the pool. In a toilet bowl of a type that flows into a flush part, a front end side is opened in a front direction with respect to the main flow of the washing water, and a rear end side is inclined with respect to the center line communicating with the trap inlet on a bottom surface of the reservoir. A toilet bowl characterized in that a toilet is formed.
