Description

[Detailed Description of the Invention] [Industrial Application Field] The industrial application field of the present invention is a flush tank capable of supplying a predetermined amount of a chemical solution such as an air freshener (including disinfectants, etc.) to the toilet side. This is the field of chemical liquid supply equipment.

[Prior Art] Conventionally, methods have been known for supplying chemicals such as fragrances, deodorizers, antifouling agents, and disinfectants into the toilet bowl. 1st
This method involves submerging a container containing a solid drug in a flushing tank, diluting and diffusing the drug from its surface into the water, and letting this diluted water flow down when water is released, leaving a portion of it to remain in the toilet bowl. It is a method. The second type is a system in which a basket-shaped storage container for solid medicine is placed at a flushing position in the toilet bowl, the medicine is dispersed in the toilet bowl by running water, and a portion of the medicine is left behind in the toilet bowl.

[Problems to be Solved by the Invention] However, the first and second prior art techniques have the following common drawbacks.

In other words, the drug is diluted and dispersed in running water, but most of it washes away with the water that flushes away the filth, and only a part of it remains in the toilet bowl. There was a waste of money being consumed without being effective.

[Means for Solving the Problems] The present invention has been made to improve the above-mentioned drawbacks, and includes a float that floats inside the washing tank main body and a frame 42 that is attached to the outer wall surface of the washing tank main body 1. And this frame 42
A chemical liquid tank containing a chemical liquid such as an aromatic liquid, a deodorizing liquid, a sterilizing liquid, etc., which can be detachably attached to the toilet, and a predetermined amount of water directly or indirectly from the tank as the float is lowered by discharging water into the toilet bowl. a taking-out means for taking out the chemical solution; a diluting means for diluting the medicine taken out as the float descends with water in the washing tank body; and a discharge means for discharging the medicinal liquid to the toilet bowl side.

[Function] If such a configuration is adopted, the medicine can be supplied to the toilet bowl after the waste in the toilet bowl is flushed away by running water from the flush tank, thereby preventing the medicine from being wasted. Furthermore, since diluted medicine solution can be supplied, the medicine solution can be reduced. Since the viscosity is reduced, the resistance to supply to the toilet bowl is small, and the medicinal solution is immediately dispersed in the standing water in the toilet bowl, allowing the medicinal solution to quickly exert its original effects. Furthermore, consumption of the chemical liquid tank can be immediately detected visually from the outside, making it easy to replace the chemical liquid tank.

The base end of the arm 47 is connected to a μ valve 48, and this valve 48 connects to a water pipe (not shown) and the base of an inverted “C” shaped water injection pipe provided in a part of the lid body 2. When the water level in the tank body 1 rises, the float 46 also rises, and when the water reaches a predetermined level, the valve 48 closes and water injection from the water injection pipe 49 stops.

Note that the water from the water injection pipe 49 passes through a 1710 part (not shown) formed in a recessed part in the center of the lid body 2 and enters the tank body 1.
It falls inside and is stored.

Next, the usage and operation of the flushing tank according to the present invention constructed as above will be explained.

When the water in the tank body 1 is at a predetermined level, the float 27 is raised, and the annular space 2 of the hollow cylindrical body 20 is raised.
Water is filled inside 0a through the opening 19a.

Further, as the float 21 rises, the bottle 31 at the upper end of the middle cylinder 27b is fitted into the cylinder body 35, and the valve 36 is opened, so that the chemical solution supplied into the cylinder body 32 via the tube 33 is delivered to the substrate 30. being led upwards.

That is, a protrusion 30a is formed on the substrate 30,
This protruding portion 30a hits the bottom surface of the bulging portion 19, and the cylindrical body 3
Since the lower part of the bulge 7 is closed, there is a certain space between the substrate 30 and the bottom surface of the bulge 19, and the chemical solution is stored in this space.

On the other hand, when the lever 10 is turned, the arm 9 is rotated, and the chain 8
Valve 6 is opened via
It is discharged to the toilet side through.

Then, the water level inside the tank body 1 decreases, and the float 21
is descending. As a result, the middle cylinder 2, which plays the role of a piston,
Cylindrical body 20 plays the role of a cylinder as 7b descends
The inside becomes negative pressure, and the valve 36 closes as shown in FIG.

When the float 27 descends and the substrate 30 reaches below the through hole 20b at the lower end of the cylindrical body 20, water in the annular space 2Oa of the cylindrical body 20 is sucked through the through hole 20b, as shown in FIG. and inflow. This state occurs just when the lower end of the float 27 comes into contact with the upper end of the cylinder 22 of the support frame 21.

When water flows into the upper side of the middle cylinder 27b in this manner, the chemical solution is diluted.

In this state, the water in the tank body 1 continues to drain, and when the drain eventually stops, the water discharged from the water injection pipe 49 begins to be stored in the tank body 1, and the water level begins to rise.

As a result, the float 27 rises, and at this time, the water-diluted chemical liquid also rises, and as shown in FIG. supplied to

The diluted chemical solution in the saucer 17 falls into the overflow pipe 3 from the opening 17a, and is discharged from the drain pipe 5 to the toilet side via the water conduit 4.

When the diluted chemical solution has been completely extruded, the bottle 31 is in a state where the valve 36 is opened as shown in FIG. 6, and the chemical solution is supplied to the upper side of the substrate 30 again.

Thereafter, the above-described operation is repeated every time the lever 10 is operated, and the diluted medicinal solution is supplied into the toilet after use.

Further, in the above embodiment, the chemical liquid was supplied to the toilet side through the overflow pipe, but it may be directly introduced and supplied into the toilet bowl by separately installing a vibrator or the like, without passing through the overflow pipe.

[Effects] As is clear from the above explanation, according to the present invention, the medicinal solution can be supplied into the toilet bowl after the waste in the toilet bowl has been flushed away by running water from the flush tank, that is, when the float is rising. Therefore, the whole of the supplied chemical solution can exhibit aromatic, deodorizing, sterilizing, etc. effects, and it is possible to prevent the chemical solution from being wasted. In addition, since a diluted chemical solution is used, there is less resistance to feeding the toilet bowl, and at the same time, the drug solution has the advantage that it is immediately dispersed into the standing water in the toilet bowl, so that the original effect of the chemical solution can be quickly exerted.

Furthermore, since the chemical liquid tank is detachably attached to the outside of the tank body, it is extremely easy to replace, and the remaining amount of chemical liquid can be seen at a glance, so that the time for replacement will not be missed.
