Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to toilet flush tanks, etc.
The present invention relates to a cleaning agent supply device for an aquarium that sprays water intermittently and fills the tank with water after water is discharged, and particularly relates to a device called a siphon type device.

<Prior art> There are two types of devices of this type: one that supplies only a cleaning solution into the tank when water is discharged into the tank, and the other that supplies a cleaning solution and other chemical solutions simultaneously into the tank. be.

Therefore, such a two-liquid supply type device has two independent
Cleaning agents and auxiliary chemicals are stored separately in the chamber, and
A drain port is provided in each chamber so that an internal cleaning agent solution and an auxiliary chemical solution are simultaneously discharged from the drain port.

<Problems to be Solved by the Invention> In such a conventional device, a drain port is formed in each of the two chambers and each chamber is configured to operate separately, so the overall shape of the device becomes large. In addition to this problem, since the two types of solutions cannot be mixed before being released, there is a problem that the mixing ratio of the cleaning component and the auxiliary drug component may be partially different in the water tank and the object to be cleaned, such as a toilet bowl. .

<Means for Solving the Problems> In the device of the present invention, the first chamber 10 containing a first agent, for example, a cleaning agent, and the second chamber 20, containing a second agent, for example, an auxiliary agent such as bleach, are arranged in an intermediate manner. Saifon room 3
The first chamber 10, which is connected vertically through the trachea 0 and located on the upper side, has first and second tracheas 40, 50 communicating with the lower part thereof at predetermined positions based on the water level when the trachea is full of water. Moreover, it is installed so as to have an opening that projects upward from the first chamber.

The first trachea 40 has a lower branch pipe 41 connected to the siphon chamber 30 and an upper branch pipe 42 that projects upward and opens, and a water storage portion 43 is formed in the upper branch pipe. .

The lower branch pipe 41 is connected to the intermediate siphon chamber 30.
The upper part 32 of the intermediate siphon chamber 30 communicates with a predetermined part other than the upper part, for example, the lower part 31.
and a predetermined portion other than the upper part of the second chamber 20, such as the lower part, are connected by a first siphon tube 60.
This first siphon tube 60 is connected to the intermediate siphon chamber 3
The upper end opening to the upper part 32 of 0 is the water intake port 61,
Also, the lower end opening at the lower part of the second chamber 20 is connected to the water inlet 6.
2, and the portion following the water intake port 61 is bent upward in an inverted U shape to form a bent pipe portion 63.

A second siphon pipe 70 is attached to the upper part of the second chamber 20, and the second siphon pipe 70 has its connecting end 71 connected to the upper part of the second chamber 20, and its discharge end 72 connected to the upper part of the second chamber 20. It is constructed so as to hang downward from the end 71.

<Function> Since the device of the present invention is as described above, when the water tank is filled with water, the first chamber 10 is filled with water up to the liquid level regulated by the internal air A1, as shown in FIG. At the same time, the second chamber 20 is also filled with water up to a liquid level regulated by internal air A2, and the intermediate siphon chamber 30 is also filled with water up to a liquid level regulated by internal air A3.

Also, in this state, the water storage portion 4 of the first trachea 40
3 and the second trachea 50 are filled with water according to the water level L of the water tank, and the water storage section 43 is normally filled with water.

Next, when the water tank performs water discharging operation, the water level L of the water tank falls to the bottom of the apparatus as shown in FIG. While the water level L of the water tank is falling, the second
The discharge end 72 of the siphon tube 70 is subjected to a ventilly effect, which causes the solution in the second chamber 20 to be discharged, which in turn causes the intermediate siphon chamber 30,
The solution in the first chamber 10 also flows into the second chamber 20 and is discharged from there.

At this time, the solution in the first chamber 10 is diluted by the water in the water storage section 43 while being applied with atmospheric pressure through the second trachea 50 and flows into the intermediate siphon chamber 30 .

When the water discharging operation of the aquarium is completed and the aquarium is filled with water again, in the process, the water in the aquarium flows back from the second siphon pipe 70 to the second chamber 20, the intermediate siphon chamber 30, and the second siphon chamber 30. It flows into the first chamber 10, the first and second tracheas 40, 50, and fills the water storage section 43 with water.

At this time, the air in the second siphon tube 70 is mixed into the second chamber due to the rising pressure of the water flowing backward, and remains in the chamber to become internal air A2, and the air in the first siphon tube 60 is further caused by the water flowing back. The air is then fed into the intermediate siphon chamber 30 and becomes internal air A3.

Subsequently, this water flowing back rises further in accordance with the water level in the water tank, and while filling the water storage section 43, it enters the first chamber 10 and seals the internal air A1 in the first chamber. 1st and 2nd trachea 40, 50
flow back inside.

At this time, the amount of water injected into the first chamber 10 is regulated by the atmospheric pressure of internal air A1, the amount of water injected into the second chamber 20 is regulated by the atmospheric pressure of internal air A2, and the intermediate siphon chamber 30 is regulated by the atmospheric pressure of internal air A3. The amount of water injected is regulated by atmospheric pressure.

Thus, the second chamber 20 and the intermediate siphon chamber 30
Since regulating the amount of water injected into the aquarium will prevent water from flowing backwards in the aquarium, the first chamber 10 and the second chamber 20 are separated by the intermediate siphon chamber 30, and the inside of the aquarium and the second chamber 20 are separated from each other by the second chamber 20. This will be blocked by the siphon tube 70.

As mentioned above, the backflow blocking action between the second chamber 20 and the intermediate siphon chamber 30 is performed by the indoor air pressure, but in reality, the space a due to the tube air or indoor air is inside the first and second siphon tubes 60 and 70. This often results in the separation of backflow water.

<Example> FIGS. 1 and 2 show an example of the apparatus of the present invention. In this example, the apparatus of the present invention has one base plate 8.
It is formed integrally with 0.

This base plate 80 is composed of a flat back plate 81 as shown in FIG. 2, and an uneven top plate 82 joined to the front side of this back plate 81. A locking portion 83 is bent in an inverted U shape toward the water tank, and is configured so that it can be connected to the aquarium by locking the locking portion 83 to the edge of the aquarium.

Due to the uneven shape formed on the top plate 82 by press molding means etc., the first chamber 10, the second chamber 20, the intermediate siphon chamber 30, the first and second tracheas 40, 5
The first and second trachea 40, 50 are opened at the locking portion 83.

Therefore, in this embodiment, when the water is full, the first
The second trachea 40, 50 opens into the air, and the water level in the tube becomes the same as the water level L of the aquarium.

The first chamber 10 houses a solid water-soluble cleaning agent 90 as a first agent, and the second chamber 20 houses a solid water-soluble cleaning agent 90 as a first agent.
contains a solid water-soluble bleach 100 as a second agent, and both agents 99 and 100 are dissolved by water injected back into each chamber.

The first chamber 10 is located above the second chamber 20, and the intermediate siphon chamber 30 is located above the second chamber 20.
It is arranged like this.

The first chamber 10 includes the first and second trachea 40,
50 is provided in communication with the lower part of the first chamber 10,
Of these, the first trachea 40 has branch pipes 41 and 42 on both the upper and lower sides.
The upper branch pipe 42 has the first chamber 1
A water storage section 43 is provided so as to be located above the opening to 0.

This water storage section 43 is made to have a volume equal to or larger than that of the second chamber 20, so that the second agent solution in the second chamber 20 can be sufficiently drained by the amount of water in this water storage section 43. It is considered.

The lower branch pipe 41 of the first trachea 40 communicates with the lower part 31 of the intermediate siphon chamber 30, and the upper end of the first siphon tube 60 communicates with the upper surface of the intermediate siphon chamber 30 as a water intake port 61.

The first siphon pipe 60 has its lower end communicating with the lower part of the second chamber 20 as a water inlet 62 for supplying water from the water storage section to the second chamber, and its upper part is shaped like an inverted U.
It is formed into a curved pipe portion 63 that rises in the shape of a curved pipe.

Therefore, the space a is formed in this bent pipe portion 63 and performs a backflow blocking function.

The second siphon tube 70 has an upper portion as a connecting end 71 and is slightly protruded from the upper surface of the second chamber 20 into the chamber. Emissions are determined.

The discharge end 72 of the second siphon tube 70 is opened downwardly, and the discharge end 72
An inverted U-shaped rising curved portion 73 is formed above the space a, thereby providing a good blocking effect by the space a.

In the above, the first siphon tube 60
It is sufficient that the water inlet 61 is located above the opening position of the lower branch pipe 41 to the intermediate siphon chamber 30, and therefore the connecting end 71 of the second siphon pipe 70 of the embodiment
It is also possible to enter the intermediate siphon chamber 30 slightly as shown in FIG.

Similarly, the connecting end 71 of the second siphon tube 70
may be located above the water inlet 62 of the first siphon tube 60, and its open end may not protrude into the second chamber like the water inlet 61 of the first siphon tube 60 in the embodiment.

The size of the space a in the intermediate siphon chamber 30 and the second chamber 20 differs depending on the amount of air mixed into the room, so if a large amount of air gets mixed into a room with a small volume, the first and second siphon tubes 60,70
Either a space will be formed above the room in addition to the space a inside, or a space will be formed above the room without the space a being formed inside the first and second siphon tubes, or on the contrary, the volume If a small amount of air enters a large room, the backflow will be blocked only by the space a in the first and second siphon tubes 60 and 70.

<Effects of the Invention> Since the apparatus of the present invention is as described above, the following effects can be expected.

Since the first agent solution is taken out from the lower part of the first chamber 10 and diluted with water stored in the water storage section 43, a predetermined amount of the first agent solution with high concentration and constant solubility is stored in the water. Therefore, a constant concentration of the first agent solution can be supplied to the second chamber 20 each time the aquarium is watered.

Since the first agent solution is supplied to the second chamber 20 and mixed with the second agent solution there, the mixed state of the solution released into the water tank is good.

When the aquarium is full, the first chamber 10 and the second chamber 20 are shut off by the intermediate siphon chamber 30, so even if the aquarium remains full for a long time, the first agent solution and the second
In addition to ensuring reliable separation from the agent solution, the second
Since the chamber 20 is also isolated from the water in the aquarium by the second siphon tube 70, it is possible to prevent the solution in the second chamber 20 from being diffused into the aquarium.
