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, the following methods have been known for supplying chemicals such as aromatics, deodorants, antifouling agents, and disinfectants into a toilet bowl. The first method is to submerge a container containing a solid drug in a flush tank, dilute and diffuse the drug from its surface into the water, and let this diluted water flow down when flushing, leaving a portion of it in the toilet bowl. It is a storage 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 medicine is diluted and dispersed in running water, but most of it flows away with the water that washes away the filth, and only a part of it remains in the toilet bowl.
Most drugs were wasted as they were consumed without exhibiting their initial effects.

[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,
A frame body 42 attached to the outer wall surface of the flush tank main body 1, a chemical liquid tank that stores chemical liquids such as aromatic liquid, deodorizing liquid, sterilizing liquid, etc., and which is detachably attached to this frame body 42, and A take-out means for taking out a predetermined amount of the chemical solution directly or indirectly from the tank as the float descends by water discharge, and diluting the chemical solution taken out as the float descends with water in the washing tank main body. and a discharge means that discharges the diluted chemical solution toward the toilet bowl as the float rises due to water accumulation in the flush tank main body.

[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 the diluted medicine solution can be supplied, the medicine solution can be The viscosity of the medicinal solution is reduced, the resistance to supply to the toilet bowl is small, and it is immediately dispersed in the standing water in the toilet bowl, allowing the medicinal solution to quickly exert its original effects. Moreover, consumption of the chemical liquid tank can be immediately detected visually from the outside, making it easy to replace the chemical liquid tank.

On the other hand, what is indicated by reference numeral 46 is a float for water level detection, which is fixed to the tip of an arm 47. The base end of the arm 47 is connected to a 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 water from the water injection pipe 49 falls into the tank body 1 through an opening (not shown) formed in the central recess of the lid 2 and is stored therein.

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 rises as shown in FIG. 3, and water flows into the annular space 20a of the hollow cylinder 20 through the opening 19a. Filled.

Also, as the float 27 rises, the middle cylinder 27b
The pin 31 at the upper end of the valve 36 is inserted into the cylindrical body 35.
is opened, and the cylindrical body 32 is passed through the tube 33.
The chemical liquid supplied inside is guided onto the substrate 30.

That is, a protrusion 30a is formed on the substrate 30, and this protrusion 30a hits the bottom surface of the bulge 19 and closes the lower part of the cylinder 37, so that the substrate 30 and the bulge 19 are connected to each other. There is a certain space between it and the bottom surface, and the chemical solution is stored in this space.

On the other hand, when the lever 10 is turned, the arm 9 is rotated, the valve 6 is opened via the chain 8, and the water in the tank body 1 is discharged via the drain pipe 5 to the toilet side.

Then, the water level in the tank body 1 decreases, and the float 27 descends. As a result, as the middle cylinder 27b, which functions as a piston, descends, the inside of the cylinder body 20, which functions as a cylinder, 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 20a 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,
When the drainage eventually stops, 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, but at this time, the water-diluted chemical liquid also rises, and as shown in FIG. is 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 is completely extruded, the pin 31 opens the valve 36 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 through a separate pipe or the like, without passing through the overflow pipe.

[Effect] As is clear from the above description, according to the present invention, after the waste in the toilet bowl is flushed away by the water from the flush tank, that is, when the float is raised,
Since the medicinal solution can be supplied into the toilet bowl, the entire supplied medicinal solution can exhibit aromatic, deodorizing, sterilizing, etc. effects, thereby preventing wear and tear of the medicinal solution. In addition, since a diluted chemical solution is used, there is less resistance to supplying it to the toilet bowl, and at the same time, it has the advantage that it is immediately dispersed in 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.
