Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to an improvement in the flush water outflow path in a Japanese-style toilet bowl or a Western-style toilet bowl.

(Prior Art) Conventionally, the toilet body of a Japanese-style toilet or a Western-style toilet is formed with a flushing water passage that has multiple outlets for flushing water into the toilet bowl at appropriate locations. It is connected to a water supply source such as a flush valve through a single water supply port provided at the front or rear part.

(Problem to be solved by the invention) However, in the above-mentioned conventional toilet bowl, since the flushing water passage is connected to the water supply source only through one water supply port, the water pressure from the flushing water outlet near the water supply port is There is a difference in the force of water from the wash water outlet located on the side farther from the water supply port or at a different height, which has resulted in disadvantages such as poor washing efficiency and increased wastage of wash water. In addition, for Western-style toilets such as blowout type and siphon jet type,
There was also the problem of poor drainage efficiency due to insufficient water pressure.

(Means for Solving the Problems) In order to solve the problems of the prior art described above, the present invention provides a water supply port for supplying water to a flushing water passage having a plurality of outflow ports formed in the toilet main body at the front of the toilet main body. and at the rear, each water supply port is connected to each water supply pipe branched from the water supply source via a three-way valve, and each water supply pipe is provided with a water flow control valve.

(Function) The flow rate and force of the wash water supplied to the wash water passage from each of the front and rear water supply ports is adjusted as appropriate by adjusting the water flow control valves, respectively, and the water is supplied from the plurality of outflow ports formed in the wash water passage. The flow rate and force of the discharged wash water can be freely set to the degree necessary for washing dirt at each position, which has the advantage of improving washing efficiency and eliminating waste of washing water.

(Example) Next, an example of this invention will be described with reference to the attached drawings.

The toilet body 1 of the illustrated Japanese-style toilet has an upper opening 2.
It consists of a toilet bowl 3, a metal hidden part 4 provided at the front part of the toilet bowl 3, a trap part 5 and a flush waste discharge part 6, which are formed in communication with the bottom part of the toilet bowl 3. A rim 7 is formed around the upper part of the toilet bowl 3 and extends inward.

The inside of the rim 7 is a hollow passage 7a, and the lower surface thereof has a plurality of rim-side wash water outlet ports 8 to 7a.
8 are arranged at appropriate intervals. The passage 7a communicates with a passage 4a formed in the metal hiding part 4, and the passage 7a and the passage 4a form a continuous waterway that goes around the entire circumference of the toilet bowl body 1. The passage 4a is configured to cause the washing water to flow out along the inner surface of the gold hiding part 4 through a front washing water outlet 9 that opens on the upper inner surface of the money hiding part 4.

The passage 7a of the rim 7 communicates with a flush water inlet 10 at the rear end of the toilet main body 1, and this water inlet 10 also communicates with a rear flush water outlet 11 provided in the toilet bowl 3. . Similarly, a flush water inlet (not shown) is also provided in the passage 4a of the metal hiding part 4 at the front end of the toilet main body 1. The water supply port at the front end and the water supply port 10 at the rear end are water supply pipes 14 and 15 branched from a three-way valve 13 operated by an operation unit 12 from a water supply source (not shown) such as a flush valve, respectively. The water supply pipes 14 and 15 each have a water flow control valve 1 in the middle.
6 and 17 are provided.

Next, the operation of the above embodiment will be explained.

Water supply piping 14,1 from the water supply source via the three-way valve 13
5 flows into the passage 4a and the passage 7a through the corresponding front end water supply port and rear end water supply port 10, and then flows from the front washing water outlet 9 and the rim side washing water outlet 8 to 8. While it flows into toilet bowl 3,
The water flows directly into the toilet bowl 3 through the water supply port 10 and from the rear wash water outlet 11.

Here, water is supplied from the front and rear ends of the series of pipes formed by the passages 4a and 7a, so the front wash water outlet 9, the rear wash water outlet 11, and the rim side wash water outlet 8 located near the front and rear ends. If the water supply amount and water supply pressure of the water supply pipes 14 and 15 are constant, cleaning water can flow out from the water supply pipes 14 and 15 at a flow rate that is approximately proportional to their opening area. The decrease in the discharge pressure from ~8 is also slight.

Furthermore, by adjusting the water volume control valves 16 and 17, the amount of wash water flowing out from the corresponding side outlet can be adjusted as desired.

The above configuration can also be applied to Western-style toilets, and in particular, by applying it to Western-style toilets such as blowout type and siphon jet type, the water pressure and amount of water from the outlet of the trap can be adjusted and drainage efficiency can be improved. can be improved.

(Effects of the invention) The present invention provides water inlets at the front and rear of the toilet body for supplying water to the flushing water passage having multiple outlets formed in the toilet body, and each water inlet is provided with water from the water supply source. By connecting each branched water supply pipe through a three-way valve and installing a water flow control valve in each water supply pipe, the flow rate and force of the wash water supplied to the wash water passage from each of the front and rear water supply ports can be controlled. By adjusting the water flow control valves, the flow rate and force of the wash water discharged from the plurality of outlets formed in the wash water passage can be freely set to the degree necessary for washing dirt at each position. Improved cleaning efficiency,
It also has the advantage of eliminating waste of washing water.
