2. Description of the Related Art As a dissolver for supplying a chemical to water in a water tank whose water level rises and falls, various dissolvers which are installed in a flush water storage tank of a flush toilet and supply a detergent to the flush water have been proposed and put into practical use. Is also provided. Japanese Utility Model Application Laid-Open No. 55-162220 discloses that a liquid cleaning agent is stored in a container body, installed in a flush toilet water tank, and a certain amount of the cleaning agent in the container is cleaned by raising and lowering the water surface when using the toilet. A container to be added to water is disclosed. Japanese Utility Model Laid-Open No. 49-133461 and Japanese Utility Model Laid-Open No. 50-69047 disclose a solid cleaning agent in a container and install the solid cleaning agent in a flush toilet water tank. A container in which a solid detergent is dissolved in washing water taken into the container by raising and lowering the water surface when the toilet is used, and a certain amount of the detergent is added to the washing water by discharging the solution into the water storage tank. Is disclosed.

Problems to be Solved by the Invention
The apparatus for supplying a liquid cleaning agent described in Japanese Patent Publication No. 220 has the advantage that a constant amount of the cleaning agent can be supplied at all times. However, since the supply apparatus is complicated and the cleaning agent must be kept in a liquid state, it is difficult to supply water. When a component having low solubility is added, a large container is required, and the container itself has to be replaced when an additional drug is supplied.

[0004] The dissolvers for solid detergents described in Japanese Utility Model Laid-Open Nos. 49-133461 and 50-69047 disclose a small-sized dissolver for chemicals having low solubility in water because the chemicals are solid. Although it is possible, a container filled with a cleaning agent is stored in the lower part of the dissolver, the dissolved water of the medicine is stored in the upper part of the dissolver, and a certain amount of the dissolved water of the medicine is released when the water surface descends. Therefore, the amount of drug that can be released into the water tank by raising and lowering the water surface at one time is small (when the drug is at the bottom, the specific gravity of the drug-dissolved water is greater than water, and the flow of water in the dissolver is Since there is no solution, the solution is homogenized only by diffusion, so that the surface of the drug is covered with a high-concentration solution and dissolution of the drug is inhibited, and the aqueous solution released above and below the water surface has a low concentration.) As the dissolution of drug progresses, The concentration of dissolved water where the distance between the dissolved water outlet is increased and discharge has the disadvantage of significantly reduced.

[0005]

[Means for Solving the Problems] The present inventors disclose a solid drug in a cylindrical container and dissolve the drug in water with a gap between the drug and the wall of the container. The drug concentration of the solution is the highest at the bottom of the cylinder, gradually decreases toward the top, and reaches a saturated concentration in a relatively short time at the bottom. It has been found that a large amount and uniform amount of the drug can be stably supplied into the water tank by releasing the drug into the tank, thereby completing the present invention.

The present invention comprises a cylindrical main body for storing a solid drug, and a flowing water thin tube connecting the bottom of the main body to the outside. The outlet of the flowing water thin tube is above the solid medicine storing portion and lower than the water surface. The dissolving device is provided in a water tank having a water surface that rises and falls, and dissolves the solid medicine in water in the water in the water tank by a fixed amount by utilizing the vertical movement of the water surface. The dissolver of the present invention may have an opening on the side surface of the main body between the outlet of the thin water flow tube and the water surface, and a partition at the lower part of the medicine storage portion of the main body that prevents the fall of the medicine but does not hinder the flow of the liquid. Can have a space part partitioned by.

The present invention will be described in more detail with reference to FIGS. 1 and 2 showing an embodiment of the present invention. The main body (1) contains a medicine, has a space between the medicine and the side wall, through which medicine-dissolved water can flow, and the shape and the like are not particularly limited as long as the structure does not allow water to leak outside. For stable installation on a wall surface, at least one side surface is preferably flat.
It is also preferable to provide a support for preventing the medicine from rolling over the side surface of the main body.

The flowing water thin tube (2) has a function of discharging the aqueous drug solution at the bottom (4) of the main body into the water tank, and the outlet (3) of the aqueous drug solution is located above the storage portion of the solid drug. The shape and the like are not particularly limited as long as they are provided at a position lower than the uppermost position of the water surface of the water tank that fluctuates up and down. It is preferably a tube of about 10 mm. Further, in order to prevent the flow of the chemical debris and the like into the flowing water thin tube, a net or projection or the like for preventing clogging may be provided at the dissolved water outflow portion at the bottom.

There is no particular limitation on the shape and the like of the medicine holder (5) as long as it can prevent the medicine from dropping and does not hinder the flow of the dissolving water. It can take the shape of

The area of the opening (6) must be at least about 5 to 10 times the area of the outflow port (3), but the shape and number thereof are not particularly limited. The position of the opening (6) is provided between the outlet (3) and the uppermost water surface (A), and the dissolution rate of the drug is adjusted by the position. It is also possible to adjust the dissolution rate of the drug by providing and placing a plurality of openings (6) at different positions and closing unnecessary openings with a stopper or the like.

The medicine supply port (7) may be open,
It is optional to provide a lid that allows the air or liquid to flow therethrough. In the open state, if the upper part is above the water surface, it becomes easy to supply the medicine.

The dissolving device can be installed in the water tank by any arbitrary method. For example, a method of hooking the upper end of the wall of the water tank with two wires attached to the upper end of the dissolving device is simple and easy. The dissolver can be installed at an arbitrary height irrespective of the structure, and is preferably adopted as a method for attaching the dissolver of the present invention. The thickness, material, etc. of the wire are selected in consideration of the weight of the dissolver, the corrosiveness of the chemical, and the like.

The material of the dissolver is not particularly limited as long as it is not corroded by the chemicals used. For example, various plastics, stainless steel and the like can be used.

The drug may be of any size and shape except that it is broken by contact with water, and the number of drugs to be injected may be one or more.

[0015]

When the dissolver of the present invention is always stored in a water tank like a low tank type water tank of a toilet, and installed in a water surface fluctuation type water tank in which water flows out of the water tank as needed,
The drug (8) dissolves upon contact with the water flowing into the dissolver, but since the aqueous solution has a higher specific gravity than water, the concentration becomes higher toward the bottom of the main body, and after a long time, a gap below the upper end of the drug is formed. An aqueous solution with a concentration close to saturation is stored. However, since the drug molecules only move to the water above the drug by diffusion, the concentration is low at a position apart from the drug, and almost no drug diffuses into the water tank from the opening (6). Absent.

When the water in the water tank is used and the water surface falls,
Most of the water in the dissolver flows out of the opening agent (6) while the water surface changes from (A) to (C), but when the water surface changes from (C) to (B), A high-concentration aqueous solution of the drug dissolved corresponding to the water in the dissolver between C) and (B) flows from the bottom of the dissolver through the narrow gap (2), and flows out of the outlet (3) into the water tank. (A)-in the case of a dissolver without an opening (6)
An aqueous solution of the drug dissolved corresponding to the water in the dissolver during (B) flows out. When the opening (6) is provided, the speed of dissolving the drug is changed by changing the position of the lower end (C) of the opening. When the opening (6) is not provided, the dissolving device is set in a water tank. Can be adjusted by changing the position of the water surface (A).

When the outflow of the stored water from the water tank is completed and water is supplied to the water tank and the water level of the water tank rises, water flows from the water tank through the outlet (3) and the opening (6) into the dissolver. Then, the water surface rises again to the position (A).

The dissolver of the present invention is installed in a water tank, such as a high tank type water tank of a toilet, in which water flows into the water tank little by little, and when the water level of the water tank reaches a certain height, the water flows out by the action of a siphon or the like. When installed, the concentration of the aqueous solution of the drug in the dissolver is slightly lower than that of the low tank type because water flows into the dissolver little by little as the water level of the water tank rises. The action dissolves the solid drug and causes its aqueous solution to flow into the water tank.

By providing the opening (6), even if the position of the uppermost water surface of the water tank and the position of the dissolver are slightly changed, it is possible to maintain a constant amount of drug dissolution rate.

When it is desired to make the amount of the drug-dissolved aqueous solution flowing out small, the body of the parts (A) and (B) is made thinner and the cross-sectional area is made smaller, so that a very small amount of the drug-dissolved aqueous solution can be discharged. Becomes

The drug-dissolved aqueous solution flowing out of the dissolver due to the fluctuation of the water surface is stored in the side-dissolved water storage (9) and the bottom-dissolved water storage (10) of the drug, and the volume of this portion is equal to the outflow drug. It must be larger than the volume of the aqueous solution. When the amount of the outflowing drug solution is small, it is not necessary to provide a drug holder (5) to secure the bottom dissolved water storage space (10). Even when the capacity of the storage space (9) is increased, the bottom dissolved water storage space (10) becomes unnecessary.

The dissolver of the present invention can dissolve a wide range of drug concentrations from a high concentration to a low concentration by a fixed amount at the same time.
By adjusting the area of the outlet (3) and making the outflow speed of the aqueous solution of the drug solution from the dissolver longer than the outflow speed of the water from the water tank, the concentration of the drug in the water flowing out of the water tank is initially low and gradually increased. Finally, the highest drug concentration can be achieved. In the case of toilet wash water or a water-washing type experimental animal breeding stand, it is effective to wash the toilet wall and the waste container with a high-concentration drug solution after flushing the waste with the wash water. A vessel is preferably used.

The present invention will be described in more detail with reference to examples. However, the scope of the present invention is not limited at all by the following Examples.

1) Dissolver and Drug The main body having the structure shown in FIG. 1 has a cross-sectional area of 50 square centimeters, a height of 25 centimeters, and a height of the drug container of 10 cm.
Three succinic acid tablets each having a diameter of 5 cm and a thickness of 3 cm were housed in a dissolver having a volume of 100 ml, which was a centimeter, and the amount of an aqueous solution of the drug flowing out from above and below the water surface. The area of the outlet was adjusted so that the outflow time of the aqueous solution of the drug solution from the dissolver was 30 seconds.

2) Performance test Rabbit breeding cages were placed in 5 rows × 3 tiers on each stage, and manure was received in a “toy” provided under the cage, and once a hour, 30 liters of washing water was applied to the toilet. The above-mentioned dissolver and chemicals were installed in a water tank of a water-washing type experimental animal breeding stand, which washes automatically from a water tank of the same type as the low tank and washes. After removing the dirt from the "toys", put one rabbit in each cage and breed them for 30 days. Observe the adhesion of the dirt to the "toys", measure the amount of drug reduction daily, and periodically The concentration of the drug in the wash water flowing out of the reservoir at the initial and final stages was measured. The outflow time of the washing water from the water storage tank was about 30 seconds. For comparison, the same test was carried out also in a case where three identical drugs were stored in a cage-shaped container and installed in a water storage tank, and also in a case where a dissolver and a drug were not installed. Add 3 medicines to the test dissolver once every 3 days, and 3 times a day to the cage.
I put in pieces.

3) Test results No stain adheres to the "toy" of the apparatus in which the test dissolver is installed even after 30 days, and the medicine is uniformly dissolved by the weight of one piece per day. The drug concentration is 40 to 6 for initial water.
