2. Description of the Related Art Conventionally, in a toilet room such as a house,
Although various flush toilets having various designs and structures are used, those flush toilets are roughly classified according to the difference in the flush water discharge method. For example, FIG. 5 is a side cross-sectional view showing an example of a flush-type flush toilet. In the case of this flush toilet, the water stored in the low tank (a) passes through the water conduit (c) of the toilet body (a). Water is supplied to the rim water passage (d), and a water injection hole (e) opened at the bottom of the rim water passage (d)
The wash water is discharged from the bowl surface (f). The dirt attached to the bowl surface (f) is washed away by the water pressure of the wash water discharged from the water spray hole (e). And, since the cleaning power is weak if the cleaning water simply flows down on the bowl surface (f), a toilet bowl is proposed in which the cleaning water flows down while swirling on the bowl surface (f) in order to enhance the cleaning power. There is.

FIG. 6 is a plan view exemplifying such a flush water type flush toilet bowl. For example, in the case of the flush toilet shown in FIG. 6, the wash water (white arrow in the figure) supplied from the low tank (not shown) to the water conduit (c) has a small hole diameter of the rim water passage (d). Due to the difference in the hole diameter between the water spray hole (e) and the large-diameter water spray port (ki), the rim water passage (d) is approximately the same in one direction, and in the meantime, the water surface from the water spray hole (e) to the bowl surface (f). I'm trying to run down. At that time, the wash water (arrow in the figure) discharged from the water spray hole (e) flows out substantially forward due to the water force, so that it swirls in one direction as a whole, but especially in the vicinity of the front of the toilet bowl. Cleaning water with stronger water force is discharged from the smaller diameter water spray holes (K) than other small diameter water discharge holes (E), which increases the swirl size and facilitates attachment of dirt to the bowl surface area (K). A large amount of washing water is supposed to be run.

However, in the case of the conventional flush toilet bowl as shown in FIG. 6, sufficient swirling liquid can be obtained by the flowing water having a strong water force discharged from the large-diameter water spray hole (K). In addition, even though the dirt adhering to the bowl surface area (K) can be efficiently washed away, a certain amount of water can be washed from the water spray holes (E) with other small diameters to clean the entire bowl surface (F). The cleaning water of must be discharged.

For this reason, a relatively large amount (about 8 liters) of cleaning water is required to make one round in the rim water passage (d) so that the cleaning water is discharged from all the water spray holes (e). is there. The present invention has been made in view of the above circumstances, and solves the problems of the conventional swirling flush type flush toilet bowl, and provides a new flush toilet bowl that can obtain an excellent cleaning effect with a small amount of flush water. Is intended.

In the flush toilet of the present invention, the flush water supplied from the water source such as the low tank is branched into right and left at the inflow portion of the rim water passage, and the water flows through the rim water passage in two directions. Since one rim water passage has a flow rate reducing structure near its inflow portion, a small amount of wash water flows, and a small amount of wash water sequentially flows down to the bowl surface from each of the water spray holes.
On the other hand, a relatively large amount of wash water flows into the other rim water passage, and most of these wash water reaches the water stop of the rim water passage while sequentially flowing down from the water spray holes. Water is discharged onto the bowl surface from a large-diameter water ejection hole near the water shut off portion. A large swirling water flow is formed on the bowl surface by the large amount of cleaning water discharged from the large-diameter water spray holes, and the area where dirt easily adheres is efficiently cleaned. on the other hand,
A small amount of cleaning water necessary for cleaning the entire bowl surface is discharged from the water spray holes having other small diameters.

EXAMPLES Examples will be shown below with reference to the accompanying drawings.
The present invention will be described in more detail. FIG. 1 is a plan view showing an embodiment of the flush toilet of the present invention. For example, in the case of this flush toilet, there is a rim water passage (3) substantially around the upper edge of the bowl surface (2) of the toilet body (1), and the rim water passage (3) is provided in the toilet body. (1) It communicates with a rear water conduit (4), and further, this water conduit (4) communicates with a water source such as a low tank through its water supply port (5).

The washing water (white arrow in the figure) supplied from the water supply port (5) to the water conduit (4) branches left and right at the inflow portion (6) to the rim water conduit (3) and is bidirectional. (A, B)
Water flows through the rim water passage (3) and is sequentially discharged from the water spray hole (7) on the bottom surface to the bowl surface (2). Since the rim water passage (3) is partitioned by the water stop portion (8) near the front of the toilet, the wash water in the two directions A and B does not join.

Further, in the rim water passage (3) in the B direction,
A flow rate reducing structure (9) is provided in the vicinity of the inflow part (6) to reduce the amount of the branched water flow flowing in the B direction. As a result, the cleaning water in the B direction is discharged in small amounts from the water spray holes (7) of the rim water passage (3). On the other hand, in the rim water passage (3) in the A direction,
A large amount of washing water flows in because the flow rate in the B direction is limited. A small amount of these washing water flows down from the water spray hole (7) of the rim water passage (3) to the bowl surface (2),
Most of the water reaches the water shut off portion (8) and is discharged to the bowl surface (2) from a large diameter water spray hole (7 ') opened in front of the water shut off portion (8). Further, in the case of the flush toilet illustrated in FIG. 1, since a large-diameter water injection hole (7 ') is also opened in the water shut-off portion (8), a large amount of wash water can be discharged from here as well. Water is spouted on (2).

A large amount of washing water discharged from these large-diameter water spray holes (7 ') with a strong water force forms a swirling water flow on the bowl surface (2), and this water flow causes an area (10) on which dirt easily attaches. ) Will be cleaned efficiently. As in the example of FIG. 1, when the large diameter water spray hole (7 ') is also provided in the water stop portion (8), the water stop portion (8)
2 can be prevented from merging with the cleaning water in the two directions A and B by using a structure shown in FIG.

Further, the flow rate reducing structure (9) provided in the rim water passage (3) in the B direction not only increases the flow rate in the A direction as described above, but also the rim water passage (3) in the B direction. Since the amount of wash water discharged from the water spray holes (7) is reduced, they do not interfere with the swirl flow water formed by the wash water in the A direction, and a large swirl flow is also formed.

As such a flow rate reducing structure (9),
For example, as shown in the YY cross-sectional view of FIG. 1 in FIG. 3, a protrusion (11) may be provided in the rim water passage (3) to increase the flow resistance. Alternatively, as illustrated in FIG.
The resistance may be increased by narrowing the entire flow path. In any case, the cleaning water in the B direction only needs to flow down a certain amount on the bowl surface (2), and the amount of the water is adjusted by appropriately setting the flow path resistance by the structure shown in FIG. 3 or 4. be able to.
