DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple flush toilet for discharging waste and cleaning the inside of a bowl using a small amount of water.

[0002]

2. Description of the Related Art Conventionally, when a seal member 2 for sealing a flap valve 1 is attached to a simple flush toilet of this type, it is performed as shown in FIG. The upper surface of the annular sealing material 2 is brought into contact with the lower surface of the peripheral edge of the discharge port 5 of the bowl 4 of the toilet bowl 3, and the locking edge 7 provided on the inner periphery of the upper end of the cylindrical valve case 6 is connected to the sealing material 2.
The valve case 6 is locked in the locking groove 8 provided on the outer periphery of the toilet bowl 3.
The seal member 2 is sandwiched between the valve case 6 and the lower surface of the peripheral edge of the discharge port 5 to support the seal material 2. The flap valve 1 is mounted in the valve case 6 so as to be rotatable up and down. When the flap valve 1 is rotated upward and the discharge port 5 is closed, the flap valve 1 elastically contacts the sealing material 2. It is designed to be sealed.

[0003]

However, since the toilet is made of pottery, the lower surface of the periphery of the outlet 5 is also made of pottery,
When the sealing material 2 is attached between the surface and the sealing material 2, the sealing material 2 is deformed into a regular shape, and when the flap valve 1 is closed, the sealing material 2 and the flap are closed. There is a problem that sealing failure occurs with the valve 1 and water cannot be stored in the bowl 4.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and has as its object to provide a sealing material which is mounted so as not to be deformed, so that poor sealing can be prevented and water can be reliably stored in a bowl.

A rim 15 is provided integrally with the upper end of the bowl 4 so as to cover the entire circumference in the circumferential direction of the upper end of the bowl 4. The water passage section 12 is provided so as to extend over. A water supply portion 16 is provided in the rim portion 15 at the rear portion of the bowl 4, and a space 17 provided at the rear portion communicates with the water supply portion 16. A lower opening 18 is provided at a lower portion of the water supply section 16 so as to face the water flow step section 12. Toilet bowl 3
A water supply tank 19 such as a low tank is mounted on the rear upper surface, and a drain port 20 for washing water is provided at the bottom of the water supply tank 19. A water supply pipe 21 is inserted into the space 17 at the rear of the toilet 3, and an end of the water supply pipe 21 on the side of the water supply tank 19 communicates with the drain port 20. Water supply pipe 21
A nozzle 22 having an injection hole is provided at the end of the bowl 4 on the side thereof, and the nozzle 22 faces the water supply unit 16. A valve case 6 is mounted below the discharge port 5 of the bowl 4 as will be described in detail later. A flap valve 1 for opening and closing the discharge port 5 is mounted in the valve case 6 so as to be rotatable up and down. It is. The flap valve 1 is connected to a lever 24 attached to a water supply tank 19 via a wire 23. By rotating the lever 24, the flap valve 1
5, the outlet 20 can be closed or opened by operating the lever 24.
On the other hand, a Douglas valve 26 is provided at the bottom of the water supply tank 19.
Is attached, and a drain valve 20 can be drained by opening and closing a float valve 28 attached to the lever 24 via a chain 27. The water supply tank 19 is provided with a drain plug 31 or a drain pipe 3 for discharging water excessively supplied through a ball tap valve 30 to the outside of the water supply tank 2.
2 are provided.

During cleaning, the lever 24 is rotated to open the float valve 28 and the water tank 19
Is supplied to the water supply pipe 21 through the drain port 20 and discharged from the lower opening 18 of the water supply section 16 to the bowl 4 as cleaning water. At the same time, the flap valve 1 is also opened, and dirt, washing water and the like in the bowl 4 are discharged from the toilet 3 through the discharge port 5. When the washing water is supplied from the drain port 20 to the water supply pipe 21, the washing water flows down from the nozzle 22 along the inner surface of the bowl 4, and the inside of the bowl 3 is washed. Thereby, the inside of the bowl 3 is effectively cleaned with a small amount of cleaning water. The arrows in FIG. 6 indicate the flow of cleaning water during cleaning.

A screw 36 such as a screw is inserted through the connection member 10 from the lower surface side of the connection member 10, and the connection member 10 is screwed into the nut 34 so that the connection member 10 is discharged from the discharge port 5.
Is mounted on the lower surface side of the peripheral edge. As shown in FIG. 4, the sealing material 2 is formed in an annular shape, and the whole is integrally formed of an elastic material such as rubber. This is for example EPDM
And SBR. A locking groove 8 is formed on the outer periphery of the seal member 2 so as to cover the entire periphery, and a thin elastic contact portion 37 is provided on the lower portion of the seal member 2 over the entire periphery. A sealing ridge 14 is provided on the upper end surface and the upper inner peripheral surface and the outer peripheral surface of the sealing material 2 so as to cover the entire circumference. The sealing member 2 is disposed below the connecting member 10, and the upper surface of the sealing member 2 is in contact with the lower surface of the connecting member 10. The seal supporting member 11 is formed in an annular shape along the connecting member 10 and the sealing member 2, and is entirely formed of a synthetic resin such as polypropylene containing glass fiber. A locking edge 38 is provided on the inner periphery of the seal supporting member 11 so as to cover the entire circumference, and the locking edge 38 is locked in the locking groove 8 of the seal material 2 to connect the seal supporting member 11 to the connecting member. It is located below 10. From below the seal support member 11
A screw 39 such as a screw is inserted through the
Is screwed into the connecting member 10 to attach the seal supporting member 11 to the connecting member 10. By attaching the seal support member 11 in this manner, the seal member 2 is attached so as to be sandwiched between the connecting member 10 and the seal support member 11. At this time, the sealing projections 14 of the sealing material 2 are elastically contacted with the connecting member 10 and the seal supporting member 11 to be mounted more watertight. The flap valve 1 is mounted on the shaft 2 in the cylindrical valve case 6.
5, the valve case 6 is disposed below the connecting member 10, and an annular seal member 40 is interposed between the upper end of the valve case 6 and the connecting member 10. is there.
A screw 42 such as a screw is inserted into the flange 41 from below the flange 41 at the upper end of the valve case 6, and the screw 4

[0010]

As described above, according to the present invention, an annular connecting member is mounted on the lower surface of the periphery of the discharge port of the bowl of the toilet bowl, and an annular seal supporting member is provided on the lower surface side of the connecting member. The upper portion of the annular sealing member is fixed along the discharge port, and is held between the annular connecting member and the annular sealing support member so as to be supported over the entire circumference, and the upper end of the cylindrical valve case is connected to the connecting member. A flap valve that is attached upwardly and pivots upward and downward in a valve case so as to resiliently contact the sealing material when the discharge port is closed, and is separate from a ceramic toilet bowl. Since the upper portion of the seal member can be attached and attached between the connecting member and the seal support member, the seal member can be attached so as not to be deformed. Water can be reliably stored.

In the invention according to the second aspect of the present invention, since the sealing ridge is provided over the entire circumference at the portion of the sealing material which comes into contact with the connecting member and the seal supporting member,
The sealing member can be more watertightly attached by contacting the sealing ridge with the connecting member and the seal supporting member.
