た。2. Description of the Related Art One type of toilet bowl is known as a one-piece toilet bowl in which a tank for storing toilet flush water and a toilet bowl body are integrally formed. In this one-piece toilet bowl, especially in the so-called low silhouette type one-piece toilet bowl where the tank is short, it is difficult to flow the washing water in the tank directly to the rim water passage at the upper peripheral edge of the toilet bowl body. In that case, a swirl hole that opens on the inner surface of the toilet bowl is provided, and the washing water in the tank is jetted into the toilet bowl from this swirl hole to generate a swirl flow inside the toilet bowl, and at the same time, a water pipe. The method of cleaning the toilet bowl was adopted by directly guiding the water from the rim to the rim water passage and spraying it from the rim water spray hole into the toilet bowl.

るサイホン作用で汚水を効率的に排出する。In the case of this one-piece toilet bowl, the sewage in the toilet bowl is drawn in by the action of the swirling flow based on the water jetted from the swirl hole, that is, the action of the vortex, and the sewage is produced by the siphon action caused by the force of the vortex. To be efficiently discharged.

いた。By the way, in the conventional one-piece toilet bowl, the rim was washed through the entire process of washing the toilet bowl. In other words, from the start of cleaning the toilet bowl, tap water is introduced into the rim water passage with direct pressure to perform rim cleaning (water spray from the rim water spray hole), and this is performed until the toilet cleaning is completed, specifically, inside the tank. The cleaning water was continuously discharged until it was sprayed from the swirl hole into the toilet bowl.

発生し、騒音の原因になるといった問題があった。However, especially in the latter stage of cleaning, it cannot be said that the water from the rim water passage is effective for cleaning the toilet bowl, and the water pressure from the rim water passage is not so strong, so that the siphon action described above is not achieved. The reality is that it is not so effective. For this reason, the conventional one-piece toilet bowl has a problem that a large amount of flush water is consumed, and since water is sprayed from the rim spray hole even in the latter stage of flushing, this spray water strikes the accumulated water in the toilet bowl. There was a problem that noise was generated and caused noise.

及びジェット孔連絡路の側へと切り替えた状態となる。In the one-piece toilet bowl of the first aspect of the present invention, when the drain port in the tank is opened at the start of toilet cleaning, the wash water in the tank is guided to the swirl hole through the swirl hole communication path. Then, the swirling hole further spouts into the toilet bowl. As a result, a swirling flow is generated inside the toilet bowl. When the water level in the tank drops as the cleaning water in the tank drains, an on-off valve provided on the water supply pipe opens an internal passage to guide tap water to the downstream side of the water supply pipe. At this time, the first switching valve downstream of the on-off valve in the water supply pipe also switches the flow of tap water to the rim communication path and the jet hole communication path.

射水孔より便鉢内に射水される。これにより便鉢内部の
リム射水による洗浄が行われる。Therefore, the tap water flows into the branch portions of the rim connecting path and the jet hole connecting path via the opening / closing valve and the first switching valve. At this point, the second switching valve is in the state where the tap water flow is switched to the rim connection channel side, so the tap water flowing downstream in the water supply pipe is guided as it is to the rim connection channel side, and It flows into the water passage and is sprayed into the toilet bowl from the rim spray hole. As a result, the inside of the toilet bowl is cleaned with rim water spray.

噴射が行われる。これによりサイホン作用が助勢され、
便鉢内の汚水が一挙に排出される。When the water level in the tank is lowered by the jet of water from the swirling hole and reaches a predetermined intermediate water level, the second switching valve switches the tap water flow to the jet hole connecting path side. . Therefore, thereafter, the water spray from the rim water spray hole is stopped, while the tap water is sprayed from the jet hole. This helps the siphon action,
Sewage in the toilet bowl is discharged all at once.

してタンク内部が満水状態になると開閉弁が閉じられ、
タンク給水が停止される。When the water level inside the tank further decreases and the inside of the tank becomes substantially empty, the first switching valve switches the flow of tap water to the side of the tank outlet. Therefore, thereafter, the supply of tap water from the rim water spray hole and the jet hole is cut off, and the empty tank is refilled with cleaning water. As a result, the water level inside the tank rises, and when the tank becomes full, the on-off valve closes,
Tank water supply is stopped.

れていないから、リム通水路内に水道水が流れ込むこと
はない。When the water level in the tank rises to the intermediate water level due to the water supply to the tank, the second switching valve again switches the flow of tap water to the side of the rim connecting path.
However, at this point, tap water is not supplied to the portion of the second switching valve, so that tap water does not flow into the rim water passage.

減も果たすことができる。In the one-piece toilet bowl of the present invention, water spray from the rim water spray hole is performed only in the initial stage of toilet flushing and not in the latter stage. That is, the rim water spraying is stopped in the latter stage of toilet cleaning, which does not contribute much to toilet cleaning or siphoning, so there is no wasted consumption of cleaning water, and there is no sound of tapping the accumulated water in the toilet bowl. For,
The advantage is that the cleaning noise is quiet. On the other hand, in the latter stage of toilet flushing, instead of rim water spraying, jetting is performed from the jet holes, effectively assisting the siphon action. As a result, the drainage performance of the wastewater is improved, and therefore the amount of washing water can be saved.

As shown in FIG. 2, the second switching valve 62 switches the flow of tap water to the jet hole communication path 58 side (FIG. 4).
t 2 ). Therefore, thereafter, the water spray from the rim water spray hole 22 is stopped, while the tap water is sprayed from the jet hole 60. This assists the siphon action, and the toilet bowl 14
The sewage therein is discharged from the outlet 36 through the trap drainage passage 28 all at once.

t 3 ), as shown in FIG. 3, the float valve 74 is seated on the drainage port 40, and the arm 78 interlocked with the chain 76 that descends is moved, whereby the first switching valve 7 is moved.
2 indicates the flow of tap water from the water supply pipe 46 to the tank spout 7
Switch to the 0 side. Therefore, the supply of tap water from the jet hole 60 is cut off, and the water that has been discharged from the tank is emptied to replenish the interior of the tank 16 with cleaning water, which raises the water level inside the tank 16.

Water spray from 2 is performed only at the beginning of toilet cleaning, not at the latter stage. Therefore, the washing water is not consumed in vain, and the toilet bowl 14 is used in the latter stage of washing.
There is no sound of tapping the accumulated water inside. On the other hand, in the latter half of the toilet cleaning, jetting is performed from the jet holes 60 instead of rim water spraying, which effectively assists the siphon action, so that the drainage performance of the dirty water is improved, and therefore the amount of flush water is also saved.
