2. Description of the Related Art Conventionally, as this type of flush toilet,
(A) JP-A-7-324368, (b) Japanese Utility Model Laid-Open No. 2
There is a flush toilet disclosed in -97473. In the flush toilet of the above (a), a water supply passage connecting a water supply chamber provided in a toilet body and a rim water passage is branched into a wash water passage and a makeup water passage, and the rim water passage is connected to the makeup water passage. A flow resistance means for delaying the supply water supply is provided, and a part of a predetermined amount of supply water supplied from a water supply source such as a water supply tank or a flush valve is retained in the supply water flow path. Then, after the end of the ball washing, the washing water retained in the makeup water flow path is sprayed from the spray hole of the rim portion to return the stored water in the ball portion to a predetermined water level. On the other hand, in the flush toilet of the above (b), the inside of the water supply chamber (3) and the inside of the rim water passage (6) are storage portions for storing makeup water. As shown in FIG. 1, the bottom wall of the rim water passage is inclined downward from the near side to the far side of the toilet body, and the bottom wall of the water supply chamber (3) is formed as a structure for forming the storage portion. It is inclined downward toward the water hole (22) on the rear wall side.

However, in the flush toilet of the above (a), a weir is provided near the outlet of the makeup water flow path, a plurality of bags are formed in the makeup water flow path, Since the flow resistance means is formed by forming the makeup water flow path in a meandering shape, precious washing water supply energy supplied from a water supply source such as a water supply tank or a flush valve is reduced. Therefore, in today's water-saving toilets, it is not appropriate to use limited water supply energy to exhibit cleaning performance. In addition, a so-called residual water phenomenon occurs in which the cleaning water retained in the makeup water flow path is continuously sprayed from the spray hole of the rim portion along the ball surface for a long time after the ball washing is completed. On the other hand, in the flush type toilet of (b), the hole diameter ratio with other water injection holes is important in order to continue the water injection from the water injection hole on the back side of the toilet body after the end of the ball washing. And the residual water phenomenon occurs similarly to the flush toilet of (a).

Next, the washing operation of the flush toilet 1 will be described. FIG. 1 shows the initial state of the stored water in the ball portion 4 before cleaning. When the cleaning operation of the cleaning water tank (not shown) is started from this state, the cleaning water is supplied from a drain port (not shown) at the bottom of the cleaning tank and a water supply port 10. Flows into the water supply chamber 11.
The washing water that has flowed into the water supply chamber 11 is supplied to the rim water passage 3b via the upper space 11a and the rim water supply chamber 3c, and is discharged from the water injection hole 3a to the ball portion 4, and then passes through the lower space 11b and the jet water passage 8. Then, water is spouted from the jet spout 7. When the washing water flows into the jet headrace 8, the air interposed between the initial water storage position 14 in the jet headrace 8 and the flowing washing water flows from the communication hole 12 to the makeup water reservoir 9. The air is pushed out and discharged, and the air in the makeup water storage section 9 is further exhausted from the air vent hole 13 to the rim water supply chamber 3c. Therefore, at the beginning of the washing operation, the air in the jet headrace 8 is hardly discharged from the jet water outlet 7 to generate noise. A part of the washing water supplied to the jet headrace channel 8 during the washing operation flows into the makeup water reservoir 9 from the communication hole 12, and
Part of the washing water also flows in from the rim water supply chamber 3c.

When a predetermined amount of washing water is supplied, a siphon phenomenon occurs in the trap drain 5 and wastes and waste water are discharged out of the flush toilet 1. At the end of the siphon, although the water at the rising portion of the trap drainage channel 5 returns, the water level of the ball portion 4 drops below the initial water level 14, and the water level in the make-up water storage portion 9 reaches the communication hole 12. It has reached the position between the air vent holes 13. Thereafter, the washing water flowing into and stored in the make-up water storage portion 9 flows out of the communication hole 12 to the jet headrace channel 8 from the communication hole 12 to its lower edge position 12a by its head pressure,
The water is supplied from the jet water outlet 7 to the ball portion 4, and the water stored in the ball portion 4 is returned to the initial water level 14.

In the above-described embodiment, the internal volume of the makeup water storage section 9 and the opening areas of the communication hole 12 and the air vent hole 13 are determined by the storage of the ball portion 4 while the cleaning water is supplied from a cleaning water tank (not shown). The value is set to a value necessary to keep the amount of washing water necessary for returning the water to the initial water level 14. The above values are determined according to the size and shape of the flush toilet and the amount of flush water. Also, since the bottom wall 3d of the rim 3 is inclined downward toward the air vent hole 13, no washing water remains in the rim water passage 3b.
Even after the cleaning operation, the residual water phenomenon in which the cleaning water flows down from the water spray hole 3a does not occur.

Next, an embodiment in which the rim portion 3 has a function of storing a part of the washing water stored in the makeup water storing portion 9 is shown in FIG.
It will be described based on. FIG. 5 is a partial cross-sectional view of the rim portion 3 having the washing water storage portion. At the center of the bottom wall 3d of the rim 3, a projection 3e projecting inside the rim water passage 3b is formed.
A water injection hole 3a is formed in the projection 3e. Projection 3
Steps 3f, 3f on both sides of e are used as washing water storages. Other configurations are the same as those of the flush toilet 1.
In the case of this embodiment, when the supply of the cleaning water from the cleaning water tank (not shown) is completed, the water is not discharged from the spray hole 3a, but a part of the cleaning water remains in the steps 3f, 3f on both sides. I have. The remaining washing water flows into the makeup water reservoir 9 via the air vent hole 13 and flows out from the communication hole 12 to the jet headrace 8.

In the above embodiment, a siphon jet toilet was described as an example. A rim cleaning water flow path for supplying cleaning water to the rim water passage, and a jet for discharging cleaning water into the pool water of the bowl portion are described. A flush toilet that does not generate a siphon phenomenon may be used as long as it is a flush toilet provided with a spout and a jet headrace for guiding washing water to the jet spout. Further, the shape of the rim water passage is such that the bottom portion is continuously opened in a slit shape over the entire circumference, and the shape surface is continuous from the ball portion to the upper edge inner portion of the rim portion, and the upper edge inner portion is a rim. The shape may be a water passage. Further, as a method of supplying the flush water to the flush toilet of the present invention, various water supply methods such as water supply by a head of a flush water tank, water supply by a flush valve, water supply by a pressurized tank, and water supply by an open / close switching valve can be adopted. .

According to the present invention, since the water supply energy of the cleaning water supplied from a water supply source such as a water supply tank or a flush valve is not reduced, the cleaning performance is not affected.
In addition, since the concealed part is used for the supply water path instead of the external part such as the ball surface, no residual water phenomenon occurs, and the design of the hole diameter of the water injection hole formed in the rim water passage, the position to be drilled, etc. A flush toilet having a degree of freedom can be realized.
