[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 3 to 5, an appropriate water-soluble agent such as a cleaning agent or an aromatic agent has been used as a chemical supply tool for a flush toilet which is suspended in a drain tank of the flush toilet. There was a container 1 in which 2 was provided with a chemical liquid communication port 5 and an opening 6 located above it.

As shown in FIG. 3, when the container 1 is completely submerged in the drain tank, this chemical supply tool for flush toilets is
The cleaning water 10 stored in the drainage tank flows into the container 1 through the chemical liquid communication port 5 and the opening 6, and a chemical liquid in which the water-soluble drug 2 is eluted is generated in the cleaning water 10. On the other hand, when the flush water 10 in the drain tank is discharged (flush) to the toilet when using the flush toilet, as shown in FIG. 5, the water level of the drain tank lowers, and the chemical liquid communication of the container 1 suspended in the drain tank is established. The mouth 5 appears on the water surface 11, and the amount of the chemical liquid substantially equivalent to the volume between the chemical liquid communication port 5 and the opening 6 flows out from the chemical liquid communication port 5 into the drain tank. The chemical solution that has flowed out diffuses into the wash water 10 in the drain tank, and then is supplied to the flush toilet through the pipe.

By the way, the water level fluctuates with the increase / decrease of the washing water 10 in the drainage tank, and a water flow is generated. Due to the influence of this water flow, the suspended chemical supply device for flush toilets tilts and tilts at an angle. It may end up. When the container 1 is in an inclined posture, the horizontal plane passing through the chemical liquid communication port 5 tilts downward in the container 1 and the region between the chemical liquid communication port 5 and the opening 6 expands. Therefore, when the water level of the drain tank drops, The amount of the chemical liquid flowing out from the container 1 in the tilted posture becomes larger than the amount of the chemical liquid flowing out from the proper posture state, and the chemical concentration of the wash water 10 in the drain tank becomes higher than the proper concentration.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to provide a chemical supply tool for flush toilets in which the chemical concentration of the wash water in the drainage tank does not become too concentrated.

[0006]

In order to solve the above problems, the present invention takes the following technical means. In the medicine supply tool for flush toilet according to the present invention, the container 1 in which the water-soluble medicine 2 is accommodated is provided with the chemical liquid communication port 5 and the opening 6 located above the communication port 5.
And is suspended in the drain tank when it is full of water, the chemical liquid communication port 5 is submerged in the drain tank and
In order to maintain the posture of the container 1 in a floating state , the container 1 is formed so that the upper side is light in the drain tank, and the container 1 is suspended at a certain position in the drain tank. When the water level of the drainage tank is lowered after the water-soluble agent 2 is eluted into the wash water that has entered the container 1 when the drainage tank is full and the chemical solution is provided,
The chemical liquid is configured to flow out from the chemical liquid communication port 5 in a state of being suspended in the proper posture.

[0007]

As a result of adopting the above means, the present invention has the following effects. When this chemical supply tool for flush toilet is hung in the drain tank when it is full, when the chemical communication port 5 is submerged, the cleaning water 10 stored in the drain tank flows into the container 1 from the chemical communication port 5. Then, the air above the chemical liquid communication port 5 escapes from the opening 6 to the outside. By the way, since the upper side is formed in a light state in the drainage tank, even if the water flow at the time of water level fluctuation causes the container 1 to take an inclined posture, the container 1 tries to put the light side upward, so that the proper posture is maintained. Return to. Therefore, the container 1 is almost always in the proper posture in the drainage tank, and when the water level in the drainage tank is lowered, the chemical liquid flows out from the proper posture state through the chemical liquid communication port 5.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2,
The flush toilet chemical supply tool of this embodiment contains a water-soluble chemical 2 in a hollow spherical container 1. Instead of the spherical shape, another suitable shape may be used. The container 1 is formed by molding synthetic resin into an upper hemisphere portion 3 and a lower hemisphere portion 4 which are separately formed, and these are screwed (thread grooves are not shown) to be coupled to each other. A solid detergent having a specific gravity larger than that of water is used as the water-soluble agent 2 and is filled below the lower hemisphere portion 4 of the container 1. In addition to the water-soluble drug 2, a desired substance such as a fragrance can be contained.

The spherical container 1 is provided with a chemical liquid communication port 5 and an opening 6 located above it. The chemical liquid communication port 5 is formed at two places in the screwed portion between the upper hemisphere portion 3 and the lower hemisphere portion 4. Then, when the container 1 is suspended from above by a suspending tool 60 made of a cord and having a constant length in the drainage tank when the container is full, the chemical liquid communication port 5 is submerged in water. The chemical liquid communication ports 5 may be formed at three or more places. Further, the opening 6 at the upper position is formed by a communication hole of a cylindrical body 7 which is erected through almost the top of the upper hemisphere 3 of the container 1. The lower end opening of the tubular body 7 is set to be located above the chemical liquid communication opening 5.

In order to maintain the posture of the container 1 properly, the container 1 is formed so that the upper side is light in the drain tank. That is, in the vicinity of the top of the upper hemispherical portion 3 of the container 1, a tubular body 7 having an opening 6 is erected so as to form an air reservoir 8 in a region above the lower end opening thereof.
By forming the air reservoir 8 in the upper region of the container 1, the upper side is in a light state. Further, the synthetic resin of the bottom portion 9 of the lower hemisphere portion 4 of the spherical container 1 is formed so as to have a thick wall, and even after the water-soluble drug 2 is almost eluted, the upper portion of the container 1 is still in the drain tank. The side is relatively lighter than the lower side, so that the posture can be properly maintained. Further, the drug solution communication port 5 is set at that position so that it is submerged even when the water-soluble drug 2 is almost eluted.

Next, the usage state of the chemical supply device for flush toilet of this embodiment will be described. When the chemical supply tool for flush toilet is arranged in the drainage tank and the chemical liquid communication port 5 of the container 1 is submerged, the wash water 10 stored in the drainage tank flows into the container 1 from the chemical liquid communication port 5. . In the container 1, the air above the chemical liquid communication port 5 escapes from the opening 6 of the tubular body 7 to the outside, and the wash water 10 reaches the position of the lower end of the tubular body 7.
Invade inside. Then, the air in the container 1 cannot escape to the outside any more, and the air pool 8 is formed in the region between the lower end opening of the tubular body 7 and the wall surface of the upper hemisphere portion 3 of the container 1. . That is, when the flush toilet is not used, the container 1 floats in the drain tank with the chemical liquid communication port 5 submerged below the water surface 11 and the upper end opening of the tubular body 7 is located above the water surface 11. Become. On the other hand, container 1
In the inside, the water-soluble drug 2 is eluted toward the saturated state in the wash water 10 that has penetrated into this, and a chemical solution is generated.

Wash water in the drain tank when using a flush toilet
When 10 is flushed to the toilet (flush), the water level in the drain tank lowers, and as a result, as shown in FIG. 2, the chemical solution in the container 1 suspended by the suspending tool 60 at a fixed position in the drain tank. The communication port 5 appears on the water surface 11, outside air enters the container 1 through the opening 6 of the tubular body 7, and the volume between the chemical solution communication port 5 and the lower end port of the tubular body 7 is almost equal. A corresponding amount of chemical liquid flows out from the chemical liquid communication port 5 into the drain tank. When suspended from above, the container 1
Is in a posture in which the chemical liquid communication port 5 appears on the water surface 11.
The chemical solution that has flowed out diffuses into the wash water 10 in the drain tank, and then is supplied to the flush toilet through the pipe.

By the way, when the flush toilet is used, the water level fluctuates with the increase / decrease of the flush water 10 in the drainage tank, and a water flow is generated. However, due to the influence of this water flow, the suspended toilet chemical supply device floats. May tilt diagonally. However, the chemical supply tool for flush toilet of this example is formed so that the upper side is in a light state in the drain tank, and when suspended in the drain tank, the water flow at the time of water level fluctuation is exerted and the slope is once tilted. Posture (As described in the section of the prior art, in this posture, the horizontal plane passing through the chemical liquid communication port 5 is inclined downward of the container 1 and the area between the chemical liquid communication port 5 and the opening 6 is enlarged. When the water level in the drainage tank drops, the amount of chemical liquid flowing out from the container 1 in an inclined posture increases more than the amount of chemical liquid flowing out from the proper posture, and the chemical concentration of the wash water 10 in the drainage tank is proper. Even if it becomes thicker than the density), the container 1 returns to the proper posture in an attempt to turn up the light side.

Therefore, the container 1 is almost always in the proper posture in the drainage tank, and when the water level in the drainage tank drops, the chemical solution flows out from the proper posture. That is, the use of the chemical supply device for the flush tank of this embodiment has an excellent advantage that the chemical concentration of the flush water 10 in the drain tank is unlikely to become too concentrated. In the above embodiment, the air reservoir 8 is formed in the region between the lower end opening of the tubular body 7 and the wall surface of the upper hemisphere portion 3 of the container 1 in the drain tank. The structure may include an air pocket. That is, all known means can be adopted for keeping the upper side of the container 1 light in the drainage tank.

[0015]

The present invention has the above-mentioned structure and has the following effects. Since the container 1 is almost always in a proper posture and the chemical solution flows out from this posture,
It is possible to provide a chemical supply tool for flush toilets in which the chemical concentration of the wash water 10 in the drainage tank is unlikely to become too concentrated.
