Abstract

PURPOSE:To obtain the same sound deadening effect as a sound imitation device while improving a water saving effect by controlling the quantity of washing water after stool by handle operation. CONSTITUTION:A stopper projection 8a is mounted integrally on the upper section side of a push rod guide 8. When a relieving person pushes and operates a handle 10 to the upper side, the handle 10 is abutted against the stopper projection 8a, a tilting distance R2 is made shorter than pushing operation to the lower side, and the travel of a push rod 7 is also shortened, thus also reducing the tilting distance of a starting rod 5 and also lowering the degree of opening of a valve body 4, then also diminishing water flowing through a water hole 14. Accordingly, an outflow sound is acquired by a small quantity of washing water, a sound deadening effect at the time of easing nature is also expected, and the inside of a stool can also be washed by a small quantity of water.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush valve for ejecting flush water into a toilet bowl.

[0002]

2. Description of the Related Art Conventionally, when a toilet is used in a toilet, especially for women, the flush valve is operated to flush the wash water into the toilet bowl, taking care that the sound may leak outside. Therefore, there is a problem in that the wash water is wasted by the outflow sound of the wash water, and the wash water is wasted. Although an onomatopoeia device that generates outflow noise may be installed, if the onomatopoeia device is attached to the wall surface of the toilet, etc., the appearance of the toilet will be deteriorated. Therefore, the onomatopoeia is not effectively used, and the flush valve is still operated to waste the washing water.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is not to provide a flash valve capable of obtaining a good onomatopoeia effect. The gist is that a starting rod that opens the valve body by tilting, and a push rod that abuts the starting rod and tilts it.
In a flash valve provided with a handle that is provided outside a push rod guide that supports the push rod and pushes the push rod toward the actuation rod side by performing a tilting operation, a part of the push rod guide has a handle side. A stopper projection protruding toward the handle is provided, and when the handle is operated, the tilting distance of the handle is shortened when the handle comes into contact with the stopper projection. A second gist is a starting rod that opens the valve body by tilting, a push rod that tilts the starting rod, a handle that pushes the pushing bar toward the starting rod by tilting operation, and an insertion of the handle. In a flash valve provided with a cover nut having a handle hole for supporting the handle, the handle hole of the cover nut is
The push rod is formed to have an opening dimension that is short upward and long downward with respect to the center of the push rod so that the tilting distance becomes short when the handle is tilted upward.

[0004]

In the first aspect, the push rod guide of the flash valve is provided with a stopper projection protruding toward the handle side. When the handle is tilted toward the stopper projection side, the handle is a stopper. The tilting distance that comes into contact with the projection is shorter than before, and therefore the tilting distance that the push rod tilts the starter rod is also shorter, which reduces the opening of the valve body and reduces the amount of flush water from the flush valve. Will be supplied to the toilet side, and the sound of flushing water will provide the same muffling effect as the conventional onomatopoeia device, and the flushing water that flows out will also provide a refreshing sensation. Since a large amount of washing water is not used unlike washing, a water saving effect can be obtained. Further, in the second aspect, since the handle hole of the cover nut for supporting the handle is formed to have a short opening upward and a long opening downward, when the handle is tilted upward, the tilting distance of the handle is shortened. The tilting distance of the starting rod that is tilted by the push rod is also shortened, the valve body is opened slightly, and a small amount of flush water is discharged to the toilet bowl, which can provide a good muffling effect and a refreshing feeling, and also save water. The effect can be improved.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment. In the drawings, a flush valve 1 has a valve seat 3 fixedly provided in a main body 2, and on the valve seat 3 is openable and closable. The valve body 4 is abutted against it via a spring, and the valve body 4 is provided with a starting rod 5 in a hanging shape. Further, a water chamber W is formed in the main body 2 above the valve body 4 by being partitioned, and the water chamber W is communicated with the water supply passage on the side of the connecting pipe 11 through the small hole 6. Has become. A push rod 7 is disposed on the lower end side of the start rod 5 in a direction orthogonal to the start rod 5, and the push rod 7 is inserted into and supported by a push rod guide 8. A cover nut 9 is screwed onto the outside of the push rod guide 8, and a handle 10 is attached to the cover nut 9 so as to be tiltable. A check valve unit 12 is connected to the upstream side of the connecting pipe 11.

In this embodiment, a stopper projection 8a is integrally formed on the upper side of the push rod guide 8 so as to project toward the handle 10 side.
When the tilting operation is performed to the upper side, the handle 10 is configured to contact the stopper protrusion 8a.

In such a structure, when the user pushes the handle 10 downward as shown in FIG. 2 after using the toilet, the handle 10 tilts downward, and the tilting of the handle 10 pushes the push rod. 7 is pressed to the left in the figure,
The left end of the push rod 7 comes into contact with the starter rod 5 and tilts the starter rod 5, and the tilting of the starter rod 5 opens the valve body 4 at the upper end of the starter rod 5 relative to the valve seat 3 and the valve body 4
When the valve is opened, the valve body 4 is suddenly moved upward by the water pressure supplied from the check valve 12 side into the connecting pipe 11, and the water accumulated in the water chamber W is released into the water holes 14, 14.
A large amount of washing water is ejected into the toilet bowl through the valve seat 3 to perform a large washing.

On the other hand, as shown in FIG. 3, when the handle 10 is pushed upward by the toilet user in the toilet,
The handle 10 tilts upward, and at this time, the handle 1
Since 0 contacts the stopper projection 8a, the tilting distance R2 is shorter than the tilting distance R1 in FIG. 2 described above, and therefore the moving distance of the push rod 7 is also short, and thus the tilting distance of the starting rod 5 is also small. Therefore, valve body 4
2 is smaller than that in the case of FIG. 2, and the amount of water stored in the water chamber W flowing out to the lower side through the water hole 14 is small, and the water inside the water chamber W is gradually passed through the small hole 6. The water filled in the water chamber W requires a short time to fill the water chamber W due to the presence of residual water in the water chamber W. Therefore, the valve body 4 is opened for a shorter time than in the case of FIG. It becomes short, and a small amount of flush water will flow out to the toilet side through the valve seat 3. Therefore, in this case, an outflow sound is obtained by the outflow of a small amount of washing water, and the inside of the toilet bowl is washed with a small amount of washing water.

For example, on the outside of the flash valve, a description of how to use this flash valve is attached for a woman or the like, and when the handle 10 is operated upward as shown in FIG. If it is written so that a good outflow sound can be obtained for, especially when a woman uses a toilet, the handle 10 is pushed upward as shown in FIG. Due to this outflow sound, the stool noise can be satisfactorily silenced, and a refreshing feeling can be obtained, and the same large amount of washing water as in the conventional large washing is not used,
Water saving effect can be obtained.

Next, FIGS. 4 to 7 show a second embodiment. In this embodiment, a cover nut 9 for supporting the handle 10 has a handle hole 9a through which the handle 10 is inserted as shown in FIG. As shown, the opening dimension h1 on the upper side is shorter than the center P of the push rod 7 and the opening dimension h2 on the lower side is longer than the center P of the push rod 7 to form an opening. The opening shape of the handle hole 9a of the cover nut 9 is changed without forming the stopper protrusion 8a, so that the flash valve 1 has a sound deadening function. The structure of the push rod 7, the starting rod 5, the valve body 4, the valve seat 3, etc. is the same as that of the first embodiment.

As described above, the handle hole 9a of the cover nut 9 is set so that the dimension h1 above the push bar center P is shorter than the dimension h2 below the push bar center. At times, as shown in FIG. 6, the handle 10 is pushed downward to tilt the handle 10 downward,
At this time, the push rod 7 is moved sufficiently to the left and the start rod 5
Tilt at a sufficient tilt angle, which causes the valve body 4 to move toward the valve seat 3
It is opened wide and a large amount of washing water is supplied to the toilet side.

On the other hand, as shown in FIG. 7, when the handle 10 is pushed upward, the handle 10 tilts upward, and at this time, since the upper opening dimension h1 of the handle hole 9a is short, the handle 10 The tilting distance R2 is smaller than the tilting distance R1 in the case of the large washing of FIG. 6, and therefore the moving distance of the push rod 7 is also short and the tilting distance of the starting rod 5 is short, and therefore the valve body 4 The degree of opening is also smaller than in the case of FIG. 6, and a small amount of cleaning water is supplied to the toilet side. In this way, when the handle 10 is pushed upward, an outflow sound due to a small amount of washing water is obtained, and the outflow sound similar to the case where the conventional onomatopoeia device is operated can be effectively silenced. It is also possible to obtain a refreshing sensation by flowing wash water.

[0013]

The flash valve of the present invention is provided on the outside of the actuation rod that opens the valve body by tilting, the push rod that abuts the actuation rod and tilts it, and the push rod guide that supports the push rod. In a flash valve provided with a handle that pushes the push rod toward the actuation rod by tilting the push rod, a stopper protrusion that protrudes toward the handle is provided in a part of the push rod guide, and when the handle is operated, The handle's tilting distance is shorter when it comes into contact with the stopper protrusion, so that when the user tilts the handle toward the stopper protrusion, the handle's tilting distance is shorter than in the case of heavy cleaning. Therefore, the moving distance of the push rod is small, the tilting of the starting rod is small, the valve body is slightly opened, and a small amount of flush water is flowed to the toilet side. , The flowing sound of the wash water can provide the same muffling effect as when the conventional onomatopoeia is operated, and the flowing wash water can provide a refreshing feeling in the toilet. In addition, a large amount of washing water is less wasted, and a water saving effect can be obtained.

Further, a starting rod that opens the valve body by tilting, a push rod that tilts the starting rod, a handle that pushes the pushing bar toward the starting rod by tilting operation, and a handle through which the handle is inserted. In a flash valve having a cover nut having a hole for supporting the handle, the handle hole of the cover nut is formed to have an opening dimension that is short upward and long downward with respect to the center of the push rod, and the handle is upward. When the handle is tilted upward, the tilt distance of the handle is shorter than that in the case of large washing, and the moving distance of the push rod is also shortened when the handle is tilted upward. This shortens the tilt of the starter bar, opens the valve element slightly, and supplies a small amount of flush water to the toilet side. Are, by the same manner as when operated with conventional sound effect device outflow sound can be obtained silencing effect, also it is possible to obtain a cooling sensation with washing water flowing,
A large amount of washing water is not wasted, and the water saving effect can be enhanced especially when a woman uses a toilet.
