Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an appropriate amount dispensing device for a chemical liquid suitable for a cleaner container installed inside a flush toilet tank, and in particular, it can be installed by simply submerging the entire device in water and requiring no position adjustment. Concerning a simple device.

[Conventional technology]

As is well known, in a flush toilet tank, water is poured and drained each time it is used, and the time that water is stored inside the tank differs depending on the frequency of use. When adding medicinal agents such as detergents and deodorants to such temporarily stored water, it is most preferable to maintain a predetermined additive concentration by adding a certain amount of medicinal agents each time it is used. . However, it is very troublesome to have to do the charging operation each time it is used, and to do this automatically by mechanical operation requires a large and expensive mechanism, making it unsuitable for general household use. Therefore, as a simple means of adding medicinal agents to the temporarily stored water inside the tank, a solid water-soluble medicinal agent is immersed in water inside the tank, and its temporary solubility allows the medicinal agent to leach into the stored water. What has been done is known. However, even when using such solid water-soluble medicinal agents, as mentioned above, the leaching concentration varies depending on the storage time, so in order to keep this concentration constant, it is necessary to keep the solid agent inside the tank. It is not effective if the area is directly submerged in water. This type of solid agent is housed inside a container, a vent hole and an inlet are provided at separate positions above and below the container or its side pipe, and water stored in the tank enters the inside of the container through the inlet and outlet, A structure (submerged type) in which the solid medicinal agent below the water level is dissolved and the aqueous solution is discharged into the tank from the inlet/outlet as the water level falls by draining the stored water;
A configuration (non-submerged type) is mainly adopted in which a discharge pipe with a trap is provided at the bottom of the container, and a predetermined amount of a medicinal aqueous solution is sent out from the discharge pipe when the stored water is discharged.

[Problems to be solved by the invention]

According to the conventional means, there are the following problems. First, the amount of a medicinal aqueous solution discharged each time depends on the installation position of the container with respect to the water level inside the tank. Second, if the interval between draining the water stored inside the tank, that is, the interval between uses, is relatively short, the additive concentration in the stored water will be kept almost constant due to the quantitative discharge function of the container, but the storage time If the storage time is long, the aqueous solution inside the container, which has a high concentration and a large specific gravity, will gradually flow out from the inlet or drain pipe, and as the storage time becomes longer, the concentration of the medicinal agent will increase. The ability to maintain a constant concentration is poor. Thirdly, if the distance between the two pouring and draining ports in the submerged type is increased, the amount of drained solution at one time will increase, and the amount of medicinal agent aqueous solution flowing out during storage will increase. For these reasons, this invention is less dependent on the frequency of use of the water stored inside the tank, and can always maintain a predetermined additive concentration.
To provide an appropriate amount dispensing device for a cleaner, etc., which can be easily installed without requiring delicate adjustment of its installation position when installed inside a tank.

[Means to solve the problem]

This invention for achieving the above-mentioned object has the following features:
As shown in Figure 2, solid water-soluble medicinal agent 3
It consists of a drug chamber 4 containing a drug chamber 4, an air discharge suction pipe 6 placed on the side of the drug chamber 4, and a siphon pipe 5 as a discharge pipe placed on the side of the air discharge suction pipe 6. It's on. The drug chamber 4 has a sealed top and a preliminary storage chamber 8a located at the bottom, and a communication port 7 located on the side at a higher level than the preliminary storage chamber 8a. The air exhaust suction pipe 6 extends upward from a lower part connected to the communication port 7, and has a vent 12 located in the head 11 and an air reservoir located above the vent 12. There is. The siphon tube 5 has a folded top portion 9
It consists of an up pipe 5a and a down pipe 5b that are connected via an up pipe 5a and a down pipe 5b, the top part 9 of which is located higher than the position of the communication port 7, and the discharge port 10 of the down pipe 5b.
is located lower than the position of the vent 12, and the lower part of the upstream pipe 5a is connected to the lower part of the communication port 7 and the air discharge/intake pipe 6. The device of the present invention having such a configuration is installed and used so as to be completely submerged inside the washing tank.

[Effect]

In the device of this invention, as shown in FIG. 3, at least the vent 12 of the air discharge suction pipe 6 is installed sufficiently submerged in water so that it is located below the upper water level 14 of the stored water. . In this installed state, the stored water 13 enters the drug chamber 4 to a point slightly above the upper edge of the communication port 7, fills the siphon tube 5, and also enters to a point slightly above the vent 12 of the air discharge/intake pipe 6. As shown in FIG. 4, as the stored water 13 is drained and its water level falls, the water in the siphon tube 5 is first drained from the drain port 10 at its lower end. Due to the action of the siphon tube 5, water inside the tube and in the drug chamber 4 communicating with the tube is discharged. This discharged water is a solution of the medicinal agent that was eluted from the flooded part at the bottom of the drug chamber 4 during the previous storage, so this solution is discharged from the storage at the same time as the stored water 13 inside the tank is discharged. It flows out while mixing with water 13. What should be noted here is that when the dissolved solution flows out from the siphon pipe 5, as the water level inside the tank falls, the dissolved solution flows out from the air discharge suction pipe 6 and the siphon pipe 5, which have a low dissolved concentration. At the end of drainage when the water level inside the tank has dropped to approximately the end position of the siphon pipe 5, the highly concentrated solution inside the chemical chamber is discharged by the siphon action. As the water is injected into the tank again and the water level of the stored water 13 rises, air is discharged from the lower end outlet 10 of the siphon pipe 5 to the air outlet 1 of the air discharge suction pipe 6.
While the air is being exhausted from the pipe 2, a part of the stored water 13 enters the pipe, and water is injected into the inside of the pipe and into the chemical chamber 4. At this time, water can be poured into the chemical chamber 4 because the upper part of the chamber is sealed.
This is done only while the air inside the room is escaping through the communication port 7, that is, until the communication port 7 is closed by the water level, and as a result, the water level in the chemical chamber 4 is reduced. It is always constant regardless of the mounting position inside the tank. When the inside of the tank is filled with stored water 13 to the extent that the entire device is submerged in water, the air discharge suction pipe 6
The air vent 12 is submerged in water, and an air pocket is formed in the sealed head, which is the initial state. When the stored water 13 inside this tank is full, the medicinal agent 3 eluted at the lower part of the drug chamber 4 has a high dissolved concentration and a high specific gravity, so that it is higher than the position of the communication port 7 of that chamber. There is no leakage into the tank through the siphon tube 5, which is provided with a folded top 9 at the position. In addition, the vent 12 of the air discharge/intake pipe 6 is submerged in water, and the head 11 of the discharge/intake pipe 6 becomes in an aerotic state due to air pockets, so that the solution inside the device does not come into direct contact with the outside air and the drug is effective. Prevents chemical odor.

【Example】

This inventive device will be described below with reference to its preferred embodiments. Fig. 1 is a front external view and a side view showing the device of this invention installed inside a flush toilet tank, and Fig. 2 is a perspective view showing the internal structure of the device with the front wall removed. It is. Structure 2 of a shell-like device (container) with a back plate 1
is integrally molded from synthetic resin. This structure 2 includes a drug chamber 4 in which a solid water-soluble medicinal agent 3 is accommodated in a space between the back plate 1 and a siphon tube 5 as a discharge tube disposed on the side of this chamber 4. It consists of an air exhaust suction pipe 6 arranged between these. The upper part of the drug chamber 4 is sealed. A preliminary storage chamber 8a is provided on the bottom surface, and a communication port 7 is provided on the side of a portion higher than the position of this chamber 8a. The siphon tube 5 consists of an up tube 5 a and a down tube 5 b that are connected via a folded top 9 . The top portion 9 is provided at a location higher than the position of the communication port 7. The lower part of the upstream pipe 5a is the preliminary storage chamber 8.
It is connected to a second preliminary storage chamber 8b provided at approximately the same height as a. A discharge port 10 is provided at the lower end of the down pipe 5b. However, as long as the lower portions of the siphon pipe 5 and the air discharge/intake pipe 6 are connected to each other and to the communication port 7 in the lower part of the device, the second storage chamber 8b does not necessarily need to be provided. The air discharge/intake pipe 6 is located so that its lower part is connected to the communication port 7 and extends upward from the lower part. The head 11 is folded down, and a vent hole 12 is provided at the folded-down end. This vent 12 is located higher than the outlet 10 of the down pipe 5b. According to this invention device having such a configuration,
As shown in FIG. 3, by installing the device inside the tank at a position sufficiently submerged in water such that the vent 12 is located below the upper water level 14 of the stored water 13, the stored water 13 can enter the inside of the device. do. In other words, the upper part of the drug chamber 4, which is sealed, forms an air pocket and is filled with water to a point slightly above the upper edge of the communication port 7 (compressed air pocket), and the siphon tube 5 is filled with water. At the same time, the air discharge/intake pipe 6 becomes airlocked by the air pocket in the head 11. Therefore, the flooded lower part of the drug chamber 4 becomes a dissolution chamber, and the medicinal agent 3 dissolves into the pre-storage chambers 8a, 8b and the siphon tube 5, but since this solution has a high specific gravity, it cannot be stored. The air stagnates in the chambers 8a and 8b, and does not flow out from the outlet 10 of the siphon tube 5 beyond the top 9 of the siphon tube 5 located at a higher position than the communication port 7, and due to the aerodynamics of the air discharge suction tube 6. Since the solution does not come into direct contact with the outside air, the odor of the medicinal agent 3 can be prevented. The deodorizing function of the air discharge/intake pipe 6 is achieved by, in addition to the embodiment shown above, for example, as shown in FIG. This is also achieved by the configuration provided. Next, the stored water 13 inside the tank is discharged,
As the water level inside the tank decreases, the solution in the siphon tube 5 first flows out from the outlet 10 at the lower end, followed by the solution at a high level inside the air discharge suction pipe 6, and the water level decreases. At the end of the drainage period when the water has fallen sufficiently, the highly concentrated solution inside the drug chamber 4 flows out from the siphon tube 5 due to its action. This outflow of the solution is completed in the state shown in FIG. 4, except for what remains in the storage chambers 8a and 8b. The spilled solution, especially the highly concentrated solution at the final stage, is poured onto the toilet wall, etc., and exerts its medicinal effects over a relatively long period of time until the next time it is flushed, increasing the cleaning effect. . When new water injection is started following this drainage inside the tank, as the water level inside the tank rises, the siphon pipe 5 is discharged while the air is being exhausted from the vent 12 of the air discharge suction pipe 6. Water flows backward from the outlet 10 and is injected into the medicine chamber 4, and when the water level inside the chamber 4 reaches the upper edge of the communication port 7, the water injection into the chamber 4 is finished, and then the air discharge suction pipe 6, and finally the initial state shown in FIG. 3 is reached. In the lower part of the chemical chamber 4 filled with this water injection, the highly concentrated dissolved solution remaining in the storage chambers 8a and 8b mixes with the newly injected water, so it is re-drained at relatively short time intervals from the time of this water injection. Even in this case, the concentration of the solution flowing out is maintained at a level sufficient for its function.

Effects of the Invention As described above, according to the device of the present invention, the solution in the upper sealed drug chamber containing a solid water-soluble medicinal agent is made to flow out through the siphon tube. Since the folded top of the device is located at a higher level than the communication port between the drug chamber and the siphon tube, the device can be easily installed by simply submerging the entire device inside the tank without the need for position adjustment. Can be installed. Moreover, it is possible to prevent the solution from flowing out even under submerged conditions, and the concentration of the solution can be kept almost constant at all times. Furthermore, since the head of the air discharge suction pipe arranged along the drug chamber together with the siphon pipe serves as an air reservoir, and a vent is provided below the head, there is no risk of air leakage due to submergence of the vent or air pocket. Due to this action, even if the medicinal agent has a unique odor such as chlorine odor, it is effective in preventing it from leaking outside.
