Description

[0001]
BACKGROUND OF THE INVENTION
The present invention stabilizes little by little in the water flowing through the main pipe, the main water pipe or main pipe, the cartridge filled with the additive, and the aqueous solution of the additive present in the cartridge. It is related with the sustained release apparatus provided with the sustained release piping for making it release gradually.
[0002]
[Prior art]
Examples of conventional sustained-release devices include JP-A-6-296902 and Japanese Utility Model Laid-Open No. 62-148189.
[0003]
In Japanese Patent Laid-Open No. 6-296902, the water is gradually released when water is passed. Japanese Utility Model Laid-Open No. 62-148189 is provided with an on-off valve in the additive passage to control the flow of the additive.
[0004]
[Problems to be solved by the invention]
However, the conventional sustained release device has the following problems. That is, in Japanese Patent Laid-Open No. Hei 6-296902, slow release is effective when water is passed, but since the slow release pipe nozzle is filled with water even when the water flow is stopped, an aqueous solution of solid or powder is used. The powder gradually diffuses and flows out of the cartridge, and the powder in the cartridge is wasted.
[0005]
On the other hand, Japanese Utility Model Laid-Open No. 62-148189 is provided with an on-off valve in the additive passage to solve the above problem, and has a structure for controlling the outflow of the additive. However, since there is an open / close valve at hand, the structure is such that the additive is placed on the shower body, so the amount of additive must be reduced, and the frequency of replacement of the additive-filled cartridge is increased. Annoying for me. In addition, when the additive is solid or powder, there is no continuous release pipe nozzle port for sustained release in the vicinity of the additive, so the saturated aqueous solution of the additive is not reliably released at a stable concentration. there were.
[0006]
An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a sustained release device for reliably and slowly releasing a saturated aqueous solution of an additive at a stable concentration when water passage is stopped. .

DETAILED DESCRIPTION OF THE INVENTION
In order to further clarify the configuration and operation of the present invention described above, preferred embodiments of the present invention will be described below.
[0030]
(Example 1: Improvement of sustained release amount stability by sustained release device)
A sustained release device 1 according to the present invention was produced as shown in FIG. 1, and a sustained release test of the additive was performed. The cartridge container 2 was filled with 60 g of citric acid 3 as an additive and filled with tap water.
The flow rate of water flowing through the main pipe 4 was 10 L / min. Water flow was intermittent (stopped and drained).
[0031]
Tap water was passed leftward from the main pipe 4 in FIG. The stopper member 5 moves to the left (downstream direction) from the original position against the force of the spring 6 by the water flow, and the slow release pipe 7 of the stopper member is connected to the slow release pipe 8 on the cartridge mounting portion side. Further, the water supply pipe 9 of the stopper member communicates with the water supply pipe 10 on the cartridge side. This state is shown in FIG.
[0032]
As a result, the saturated aqueous solution of citric acid in the vicinity of the citric acid 3 filled in the cartridge container 2 flows upward through the pipes 11 and 12, and the slow release pipe 8 and the stopper member on the cartridge mounting side. The continuous flow pipe 7 is joined with the water flow from the main pipe 4, and citric acid is released slowly. Since the water is replenished from the water replenishing pipe 9 of the stopper member and the water replenishing pipe 10 on the cartridge side by the amount of the gradually released water, the cartridge container 2 is always full of water. The slowly released water of citric acid flows to the left in FIG.
[0033]
Since citric acid is consumed as the water passes, the amount of citric acid in the cartridge container 2 also decreases. At this time, since there is a weight 13, the tip of the pipe 11, that is, the nozzle opening 14 portion of the slow release pipe is always present. It is in the vicinity of citric acid and will continue to release the saturated aqueous citric acid solution. This state is shown in FIG.
[0034]
Incidentally, when the water flow through the main pipe is stopped, the slow release pipe 7 of the stopper member and the slow release pipe 8 on the cartridge mounting side, and the water supply pipe 9 of the stopper member and the water supply pipe 10 on the cartridge side are connected to the water passage. Are blocked (in the state shown in FIG. 1), the slow release of citric acid and the water supply are stopped.
[0035]
FIG. 4 shows the sustained release amount of citric acid with respect to the water passage time when the sustained release device of FIG. 1 is used. Here, the sustained release amount of citric acid is shown as the pH of the water discharged from the sustained release device as a substitute characteristic, and the diameter of the sustained release pipe 7 and the diameter of the water supply pipe 9 in the stopper member are set to pH 6 and the stopper The diameter of the pipe 15 that receives water from the main pipe 4 in the member is adjusted to allow water to pass. FIG. 4 shows that the sustained release amount of citric acid is very stable, and thus the superiority of the sustained release device of the present invention shown in FIG. 1 was shown.
[0036]
In FIG. 1, the shape of the pipe 15 that receives water from the main pipe 4 in the stopper member may be any shape.
A straight tube 17 as shown in FIG. 10 or a straight tube 17 as shown in FIG. 10 may be used when the gap between the inlet side and the outlet side is tapered as shown in FIG. 1 or when a step is provided as shown in FIG.
[0037]
(Example 2: Test 1 with a conventional sustained-release device)
Using the apparatus as shown in FIG. 5 as the conventional sustained release apparatus 100, the sustained release test of citric acid was conducted in the same manner as in Example 1.
[0038]
Tap water was passed leftward from the main pipe 101 in FIG. By passing water, the aqueous solution of citric acid 3 filled in the cartridge container 102 flows upward through the slow release pipe 103 and merges with the flow of water in the main pipe 101 to gradually release citric acid. Similarly to FIG. 1, since the water is replenished from the water replenishment pipe 104 by the amount of water that has been gradually released, the cartridge container 102 is always full of water. The slowly released water of citric acid flows to the left in FIG.
[0039]
FIG. 6 shows the sustained release amount of citric acid with respect to the water passage time when the sustained release device of FIG. 5 is used. Although the water is passed by adjusting the diameter of the slow release pipe 103 and the diameter of the water supply pipe 104 with a target of pH 6, the pH is not stable at all and the pH is about 6.5 after 20 minutes. It will rise. That is, it shows that the sustained release amount of citric acid 3 has decreased, and it can be seen that the sustained release device shown in FIG.
[0040]
This is because the slow release pipe 103 is short and the tip of the pipe, that is, the nozzle port 105 is not in the vicinity of citric acid, so that the saturated solution of citric acid is not always released gradually, but the water from the water supply pipe 104 is gradually released. This is considered to flow out of the discharge pipe 103.
[0041]
(Example 3: Test 2 with conventional sustained-release device)
Furthermore, using the apparatus as shown in FIG. 7 as the conventional sustained release apparatus 110, a sustained release test of citric acid was conducted in the same manner as in Examples 1 and 2.
[0042]
Tap water was passed leftward from the main pipe 111 in FIG. By passing water, the aqueous solution of citric acid 3 filled in the cartridge container 112 flows upward through the slow release pipe 113 and merges with the flow of water in the main pipe 111 to gradually release citric acid. Similarly to FIGS. 1 and 5, since the water is replenished from the water replenishment pipe 114 by the amount of the gradually released water, the cartridge container 112 is always filled with a full amount of water. The slowly released water of citric acid flows to the left in FIG.
[0043]
FIG. 8 shows the sustained release amount of citric acid with respect to the water passage time when the sustained release device of FIG. 7 is used. The diameter of the slow release pipe was adjusted with a target of pH 6, and the slow release pipe was extended to the vicinity of the citric acid powder to pass water. However, as can be seen in FIG. 8, the pH always decreased at the initial stage of intermittent water flow. This indicates that the sustained release amount of citric acid has become large at the beginning of water flow, which is not desirable. After that, if a certain amount of water is passed, the target pH is obtained. Although desirable in this respect, citric acid is decreased, and the pH increases as the nozzle port 115 of the sustained release pipe is further away from the citric acid. The pH then drops again, and eventually takes on a mysterious behavior that suddenly rises and ends. At this time, all of the citric acid is not lost and remains a little. Thus, as shown in FIG. 7, if the length of the sustained release pipe is increased, instability remains in the sustained release, and the additive is wasted.
[0044]
This is because the slow release pipe is in the vicinity of citric acid at the time of initial water flow with a lot of citric acid, and the performance is good because it is long enough, but the citric acid decreases with the water flow, but with the pipe tip, That is, since the nozzle port moves away from the vicinity of citric acid, the situation is similar to FIG. 5 in which the water from the water supply pipe immediately flows out of the slow release pipe instead of the slow release of the saturated citric acid solution. It is thought to become.
[0045]
【The invention's effect】
By using the sustained release device, a saturated aqueous solution of the additive present in the cartridge filled with the additive can be stably and gradually released into the water flowing through the main pipe.
Further, since the additive filling amount can be changed by changing the size of the cartridge filled with the additive, the cartridge replacement life can be extended.
