Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention includes a toilet tank sealing mechanism that seals the discharge part of the lower part of the toilet bowl so that the discharge part can be opened and closed; The present invention relates to a simple flush toilet equipped with a seal gasket for closing a gap with the toilet tank sealing mechanism, which is improved so that the seal gasket can be attached and removed without removing the toilet bowl.

``Prior Art'' In Japan, the areas where flush toilets can be installed are currently limited to urban areas and their surrounding areas, and this is because the spread of sewage facilities has lagged behind. In order to compensate for the delay in sewerage facilities, septic tanks are used to flush water. However, in some regions, it is regulated to discharge treated water from septic tanks into rivers.
Septic tanks cannot be used in such areas. Therefore, simple flush toilets, which can provide the same feeling of use as a flush toilet, have come to be widely used.

FIG. 4 shows the installation status of a conventional simple flush toilet B. As shown in the figure, the simple flush toilet B is provided with a storage box 11 at the bottom.
It is connected to the defecation pipe 12 that communicates with the toilet tank. Inside the storage box 11, there is a discharge port 1 at the bottom of the toilet bowl _B1 .
A toilet tank sealing mechanism 14 is housed therein, which seals the toilet tank 3 in an openable and closable manner to block bad odor from the toilet tank and wind blowing up from below.

FIG. 5 is an enlarged cross-sectional view of the vicinity of the discharge port 13 of the toilet bowl _B1 . The toilet tank sealing mechanism 14 shown in the same figure is a rotary opening/closing automatic flapper mechanism, and includes a waste receiving part 14b pivotally supported by a shaft 14a and a weight 1 provided at the side end.
It consists of 4c. When waste falls into the receiving portion 14b, the toilet tank sealing mechanism 14 rotates as shown by the two-dot chain line under the weight of the waste, and after discharging the waste in the open state, returns to the original closed state by the action of the weight 14c. to return to.

A seal packing 15 is attached to the discharge port 13 at the bottom of the toilet bowl _B1 . The seal packing 15
is for closing the gap between the receiving portion 14b of the toilet tank sealing mechanism 14 and the discharge port 13 to form a water storage portion. Normally, the simple flush toilet B is not provided with a trap that is provided in a flush toilet. Therefore, as an alternative to the trap, a small amount of cleaning water is stored in the outlet 13 to form a water reservoir. The water reservoir portion seals the discharge port 13 to block bad odor from the toilet tank, and also prevents filth from adhering to the receiving portion 14b, thereby facilitating the discharge of filth. It is desirable to provide the seal packing 15 to ensure the formation of this water reservoir. In addition, when the toilet tank sealing mechanism 14 automatically returns after discharging waste, the metal or resin receiving portion 14b of the seal gasket 15 collides with the lower surface of the ceramic discharge port 13 and damages each other. It also has the function of preventing

"Problems to be solved by the invention" Since the seal gasket 15 is constantly under compressive force from the receiving part 14b of the toilet tank sealing mechanism 14, and the toilet bowl B is regularly cleaned with chemicals, the material may deteriorate or deform. , deterioration is likely to occur and must be replaced every 2 to 3 years. However, as shown in FIG. 5, the conventional mounting structure was such that the seal packing 15 was attached to the outlet 13 at the bottom of the toilet bowl from the outside, so in order to perform the replacement work, the toilet bowl B had to be removed from the installation location. Moreover, it had to be turned over, which required a great deal of time and effort.

"Means for Solving the Problems" In view of the above-mentioned problems, the present invention has made it possible to attach and detach the seal gasket without removing the toilet bowl. This will be explained with reference to FIG. 1, which is an enlarged sectional view of a main part of an embodiment of the present invention.

The feature of the present invention is that the toilet bowl A ₁ has a discharge part 10 for discharging filth, etc. at the bottom thereof, is equipped with a toilet tank sealing mechanism 5 that seals the discharge part 10 in an openable and closable manner, and In a simple flush toilet A equipped with a seal gasket 1 for closing the gap between the toilet bowl sealing mechanism 5 and the toilet tank sealing mechanism 5, the seal gasket mounting member 2, which has the discharge section 10 provided below, is attached to the bottom of the toilet bowl _A1 . The seal packing 1 is connected to the lower surface of the discharge port 9, and the seal packing 1 is connected to the inner circumferential surface 2a of the seal packing mounting member 2.
The inner circumferential surface of the seal packing mounting member 2 is locked to a locking portion 20 provided around the lower end or near the lower end, and the packing holding tool 3 can press against and separate from the seal packing 1 from the upper surface side. attached to 2a,
A filling gasket 4 made of an elastic material such as a sponge is installed between the top surface of the gasket retainer 3 and the bottom surface of the discharge port 9 at the bottom of the toilet bowl _A1 .

"Function" Seal packing 1 is seal packing mounting member 2
Since it is locked on the inner surface side of the toilet bowl _A1 , the seal gasket 1 can be easily attached and removed from the inner surface side of the toilet bowl A1 without removing the toilet bowl A. The seal packing retainer 3 is attached to the inner circumferential surface 2a of the seal packing mounting member 2 so that it can press against and separate from the seal packing 1 from the upper surface side. This can be done from the inner side of ₁ . Since the filling gasket 4 is installed between the upper surface of the gasket retainer 3 and the lower surface of the discharge port 9 at the bottom of the toilet bowl _A1 , the inner circumferential surface 2a of the seal gasket mounting member 2 and the gasket retainer 3 are filled. 3, the attachment part of the packing press stopper 3, etc., will not have dirt attached to them.

"Embodiment" Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1, which is an enlarged sectional view of a main part of a simple flush toilet A.

A storage box 6 is provided at the bottom of the simple flush toilet A, and the storage box 6 connects the toilet A to a defecation pipe 12. The seal gasket mounting member 2 and toilet tank sealing mechanism 5 are housed in the storage box 6. That is, the seal gasket mounting member 2 is a cylindrical member that hangs down from the upper surface of the storage box 6, and the lower opening is used to remove filth, etc. from the defecation pipe 12.
A discharge section 10 is configured to discharge the water to. Therefore,
By joining the lower surface of the toilet bowl A ₁ and the upper surface of the storage box 6 using a clamp 7, a tightening band 8, etc., the seal gasket attachment member 2 communicates with the discharge port 9 at the bottom of the toilet bowl A ₁ . On the other hand, the toilet tank sealing mechanism 5
is housed in the storage box 6 so as to seal the above-mentioned discharge section 10 so that it can be opened and closed.

A locking portion 20 for locking the seal gasket 1 is provided at the lower end of the seal gasket mounting member 2. The locking portion 20 is an annular projection that projects inward. Furthermore, a female thread for screwing the sealing stopper 3 is cut into the inner circumferential surface 2a of the seal packing mounting member 1. The length of the female screw portion is such that when the sealing stopper 3 is separated from the sealing packing 1, a separation distance that allows the sealing packing 1 to be removed and replaced can be obtained.

The seal packing 1 is a ring-shaped flexible member made of Teflon or the like. Its inner diameter is toilet bowl A ₁
It is desirable that the diameter be the same as, or slightly larger than, the diameter of the outlet 9 at the bottom, and that the outer diameter substantially match the inner diameter of the seal packing mounting member 2. A locking groove 1a that engages with a locking portion 20 of the seal gasket mounting member 2 is provided on the outer peripheral surface of the seal gasket 1. When the locking groove 1a is engaged with the locking portion 20 of the seal gasket attachment member 2, the lower end of the seal gasket 1 is configured to slightly protrude from the lower end of the seal gasket attachment member 2. Therefore, since the seal gasket 1 comes into close contact with the receiving portion 5a of the toilet tank sealing mechanism 5, a water reservoir can be formed in the discharge portion 10.

The packing retainer 3 is a ring-shaped member having an inner and outer diameter that is approximately the same size as the seal packing 1. A male screw corresponding to the female screw of the seal packing mounting member 2 is carved on the outer peripheral surface, and is screwed onto the upper surface side of the seal packing 1. Therefore, by tightening and untightening the seal packing 3, the seal packing 1 can be pressed and separated from the top side.

The filling gasket 4 is a ring-shaped member made of an elastic body such as a sponge, and has an inner and outer diameter approximately the same as those of the seal gasket 1 and the gasket retainer 3. Seal packing 1 and packing holding tool 3
When pressed and fixed, a recess H is formed between the upper surface of the gasket press stopper 3 and the lower surface of the outlet 9 at the bottom of the toilet bowl _A1 . Therefore, filth and the like remain in the recess H as the toilet is used. In particular, when a female screw is carved on the inner circumferential surface 2a of the seal packing mounting member 2 as in this embodiment,
Dirt can easily adhere to it. The adhesion of dirt, etc. not only causes a bad odor, but when it dries and solidifies, it prevents the sealing pad 1 from loosening.
make replacement work difficult. Therefore, the filling gasket 4 was filled into the recess H to prevent dirt and the like from adhering to the inner circumferential surface 2a of the seal gasket mounting member 2. Note that if the height of the filling packing 4 is made slightly larger than the width t of the recess H and the filling packing 4 is installed in a compressed state, the filling state will be more reliable.
Furthermore, when the filling packing 4 is manufactured by molding a sponge, a water-impermeable film is formed on the surface, so that penetration of sewage, urine, etc. can be prevented.

FIG. 2 is an exploded perspective view of the seal gasket mounting member 2, the seal gasket 1, the gasket retainer 3, and the filling gasket 4. A method for attaching the seal packing 1 will be explained using this. First, the toilet bowl
Before joining A ₁ and the storage box 6, the seal packing 1 is attached to the seal packing mounting member 2. First, the seal packing 1 is engaged with and attached to the locking part 20 of the seal packing mounting member 2, and
Next, the seal packing stopper 3 is screwed onto the inner circumferential surface 2a of the seal packing mounting member 2 and tightened to press and fix the seal packing 1 from the upper surface side. continue,
The filling gasket 4 is attached to the top surface of the gasket presser 3, but the filling gasket 4 is attached to the gasket presser 3 in advance.
It may also be pasted on the top surface. Thereafter, the lower surface of the toilet bowl _A1 of the simple flush toilet A and the upper surface of the storage box 6 are joined. The filling gasket 4 is installed by joining the bottom surface of the toilet bowl A ₁ and the top surface of the storage box 6, and then pushing it into the recess H (see Fig. 1) between the top surface of the gasket holding tool 3 and the bottom surface of the toilet bowl. It is also possible to do so.

Next, a method for attaching and replacing the seal packing 1 according to the present invention will be explained. Toilet bowl A ₁ and storage box 6
While maintaining the jointed state with the seal gasket 1, the gasket retainer 3 is rotated from the inner surface of the toilet bowl _A1 and separated from the seal gasket 1. In this case, if the notch grooves 30 and 40 as shown in FIG. Insert it into the discharge port 9 at the bottom of the pot, and press the packing stopper 3.
It is possible to rotate. Further, the inner diameter of the filling packing 4 may be made slightly larger than the inner diameter of the packing holding tool 3 so that the notch groove 30 of the packing holding tool 3 is located inside the inner circumferential surface of the filling packing 4. Since the filling gasket 4 is an elastic body, it does not become an obstacle when separating the gasket retainer 3 from the seal gasket 2. In other words, the packing retainer 3 can be rotated while the filling packing 4 remains attached without being removed. Furthermore, if the packing retainer 3 and the filling packing 4 are attached in advance, the rotation operation will be easier.

Following the unthreading of the seal retainer 3, the seal seal 1 is removed from the seal seal mounting member 2.
Since the seal packing 1 has flexibility, a toilet bowl with a diameter smaller than the outer diameter of the seal packing 1 can be used.
It can be pulled out from the _A1 discharge port 9 with bare hands, or it can be pulled out using an appropriate tool.

After that, install a new seal packing 1 by reversing the above procedure. That is, the seal packing 1 is pushed into the seal packing mounting member 2 from the outlet 9 of the toilet bowl A ₁ by utilizing its flexibility, and pushed down until the locking portion 20 and the locking groove 1a are engaged. Then, the seal packing holder 3 is rotated and tightened again to press and fix the seal packing 2. The filling packing 4 returns to its original filling state by elastic force.

The mounting structure of the seal packing 1 of the present invention is not limited to the above-mentioned structure, but is shown in FIGS. 3a to 3f.
The following applications are possible. That is, the locking portion 20
The tip of the locking part 2 is tilted upward [see figure a].
A rib 21 for preventing slippage is provided upright at the tip of the seal packing 1 (see figure b), and a locking step 1 is provided on the outer peripheral surface of the seal packing 1.
It is possible to use a structure in which the locking part 20 is locked by providing the locking part 20 around the locking part 20 (see c in the same figure).
0 can also be provided slightly above the lower end of the seal packing mounting member 2 [FIG. d to f].

Further, the toilet tank sealing mechanism 5 stored in the storage box 6 is not limited to the automatic flapper mechanism shown in this embodiment, but may also be a pedal-operated or other mechanical sealing flapper mechanism. good.

``Effects of the Invention'' As explained above, according to the present invention, the seal gasket can be replaced without removing the toilet bowl, so it is possible to quickly deal with deterioration of the seal gasket. Therefore, the discharge part at the bottom of the toilet bowl is kept well sealed at all times, eliminating foul odors and
It is sure to block blowing wind, etc., and prevent flies, etc. from entering the toilet.

Since the filling gasket is filled and installed in the recess between the gasket retainer and the bottom surface of the toilet bowl, dirt does not adhere to or remain on the inner circumferential surface of the seal gasket mounting member. Therefore, it is possible to prevent bad odors, and the pressing and separating operations of the sealing stopper can always be performed smoothly, making it easy to attach and replace the sealing packing.

In addition, as shown in the embodiment, if the inner diameters of the seal packing, packing stopper, and filling packing are made approximately equal, and the diameter of the toilet bowl discharge port is made the same as or slightly smaller than the inner diameter, the discharge port portion can be covered with an eaves. It is effective and makes it difficult to see the inner part, which improves the aesthetic appearance, and the seal retainer does not separate from the seal seal mounting member when unscrewing, so there is no chance of losing it due to incorrect operation. .
