[0006]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the drawings. The body 1 of the toilet bowl can be connected to the sewage pipe 4 by a connection port 11. In the illustrated case, the basin 3 on the upper part of the main body 1 is formed separately, and the two can be combined to receive filth. However, both can be formed integrally. In addition, various joining methods may be used at the respective joining locations as necessary, to obtain better tight joining properties and prevent water leakage.

The main body 1 is provided with a water liquid valve 12. One end of the water liquid valve 12 is connected to a water supply pipe 13 to draw in water, and the water supply pipe 13 is connected to a general water tap. can do. The other end of the water liquid valve 12 is connected to the water supply pipe 17, and the water supply pipe 17 is formed so as to correspond to the fountain hole 31 of the reservoir 3.

The water that has entered the main body 1 from the water supply pipe 17 through the fountain hole 31 flows into the water storage tank 14 through a connecting pipe 18 described later. A floating ball 15 is provided in the water storage tank 14. The floating ball 15 can be lowered by its own weight, or can be raised together with water rising by buoyancy, and the valve rod 16 can be moved. That is, the bubble rod 16 can be swung up and down by the lowering or rising of the floating ball 15, thereby stopping or opening the water from the water liquid valve 12.

The water flowing into the main body 1 from the water supply pipe 17 can accumulate in the main body 1 and communicate with the water storage tank 14 by the connecting pipe 18 as described above. If the connecting pipe 18 is preferably formed of a pipe having a diameter of about 10 cm, it can be used for communicating the water storage tank 14 with the main body 1 without clogging with dirt. Can store an appropriate amount of water. Generally, if the water storage surface of the main body has a width of about 20 to 25 centimeters and the depth of the water level is about 7.5 cm or more, it is possible to effectively prevent the attachment of dirt to the main body. However, it is preferable because odor leakage from the sewage pipe is prevented. The water stored in the main body 1 and the water storage tank 14 is discharged from a drain port 19, and the connecting pipe 18 is opened through a drain port 19 leading to the sewage pipe 4.

When this is used, when the tread provided on the control rod 23 is stepped on, the on-off valve 2 opens and the drain port 19 is opened, so that all dirt is normally discharged within 2 seconds. The opening and closing of the drain port 19 is formed so as to be controlled and operated by the piston 29 of the on-off valve 2. The piston 29 is placed in the piston chamber 20 and both have relatively good bonding properties. The piston 29 can be guided up and down by a pair of protruding guide pipes 21 guided by a groove 22 provided in the piston chamber 20. As a result, the piston 29 can seal and open the drainage port 19 as it moves up and down.

The piston 29 is controlled by the control rod 23 to move up or down by its own weight to return to its original position. However, the piston 29 is urged by a spring or the like to be at the lower position. You may keep it. The piston 29 is formed of a hollow cylinder, and is provided with a hole 24 at the bottom thereof. The hole 24 is formed so as to be located at the lowest position by using a slope forming the bottom.

Since the hole 24 is normally (mostly) closed by the sphere 25, it is possible to prevent odor from leaking from the sewage pipe. The piston 29 can receive the water overflowing from the overflow hole 32 of the main body when the water flow cannot be stopped due to the failure of the water liquid valve 12. Also, the water entering the piston 29 causes the sphere 25 to rise due to its buoyancy, and the hole 24 is formed so as to open, so that abnormal water flows into the sewage pipe 4 from the hole 24 and is discharged. Will be done.

A fountain hole 31 is provided in the basin 3 at the upper part of the main body 1, and is formed so as to correspond to the water supply pipe 17 of the main body 1. In addition, an overflow hole 32 is provided in the basin 3 so that the water liquid valve 12 cannot be closed due to a failure as described above. 32 can flow into the piston chamber 20 and the sphere 25 rises and flows into the sewage pipe 4 through the drain hole 24 and is discharged.

FIG. 2 shows a state in which the water flow is normal and the water is stored. The drain port 19 of the main body 1 is sealed by a piston 29 of the on-off valve 2 so that water is stored in the main body 1 and the water stored in the water storage tank 14 through the connecting pipe 18 raises the floating ball 15 to an appropriate height. And the water liquid valve 12 is closed to prevent water supply. Further, the odor coming out of the sewage pipe 4 is sealed off by the water and the sphere 25 placed on the hole 24, respectively, so that the problem that the odor leaks is eliminated.

FIG. 3 shows a case where the waste collected in the main body 1 in the state of FIG. 2 is discharged. By stepping on the control rod 23, the piston 29 of the on-off valve 2 is raised, and the drain port 19 is opened. The dirt and water accumulated in the main body 1 are quickly discharged from the drain port 19 together with the water accumulated in the water storage tank 14, and a relatively large flushing force is formed. The water-liquid valve 12 is opened as the water level in the water storage tank 14 decreases, and water from the water supply pipe 17 flows out of the ejection hole 31 into the main body and is washed away, so that it is possible to prevent the remaining of dirt. . The amount of water required to drain the filth in the main body under normal conditions is about 2.5 to 3 liters. If the control rod 23 is continuously depressed, the outflow of water from the ejection hole 31 can be continued.

FIG. 4 shows details of the water liquid valve 12 and the water storage tank 14. The water liquid valve 12 can draw in water from the launch pipe 13 and flow into the main body 1 from the water supply pipe 17. The water flowing into the main body takes the connecting pipe 18 and flows into the water storage tank 14. A floating ball 15 is provided in the water storage tank 14, and the floating ball 15 can drop by its own weight or rise by the buoyancy of water. By lowering or raising the floating ball 15, the valve rod 16 can be pulled so as to swing up and down, whereby the water from the water liquid valve 12 can be prevented or opened.

After the above-mentioned filth is flowed from the main body 1 to the sewage pipe 4, when the stepping on the control rod 23 is stopped as shown in FIG. After returning to the position, the drain port 19 is closed again, and the water flowing out of the water supply pipe 17 can again be stored in the water storage tank 14 through the main body 1 and the connecting pipe 18. Then, the water accumulated in the water storage tank 14 is pushed up so as to raise the floating ball 15 to close the water liquid valve 12 to prevent the water supply, and the water is maintained at a constant water level, and the state shown in FIG. Return to At this time, since the sphere 25 in the piston 29 seals the hole 24, there is no problem that the odor coming from the sewage pipe 4 leaks.

FIG. 6 shows a case where the water flow is abnormal. If the water liquid valve 12 fails and the water flow does not stop, the water that continues to flow into the main body is opened and closed through the overflow hole 32. The water flows into the piston chamber 20 of the valve 2, and the sphere 25 in the piston 29 is raised by the buoyancy of the flowed water, so that the hole 24 is opened and the water can flow into the sewage pipe 4.
