It is arranged to be inserted into the outlet 31a. As a result, when the valve 33 moves up and down following the movement of the diaphragm 32b, the valve stem 33b
Is guided by the hole walls of the medicine passage port 32c and the medicine outlet 31a to move up and down, and the medicine passage port 3 of the valve body 33a is moved.
The separation / contact operation to and from 2c is ensured. The medicine in the medicine tank 31 flows into the medicine dripping chamber 32 when the valve body 33a moves away from the medicine passage port 32c. The valve body 33
A spring 33d for urging the two in the direction away from each other is disposed between the spring 33a and the inner surface of the diaphragm 32b.

The medicine ejection pipe 34 is provided projecting below the diaphragm 32b. The medicine ejection pipe 34 is formed by compressing the medicine dropping chamber 32 and increasing the internal pressure. Is formed in such a diameter or structure that the medicine flowing into the container is dropped by a required amount. Although it depends on the type of the medicine, it is usually 0.01 to the amount of washing water taken into the inner box 11 of the main body case 10.
cc is enough, and even when the flush toilet 13 is used continuously, if this agent is supplied once in 1 to 5 minutes, the washing and bacteriostatic effects are sufficient. Therefore, for example, the felt ejection pipe 34 is filled with a felt core material,
If the structure is such that the medicine is transmitted through the core material by the capillary phenomenon, the above-described small discharge amount can be obtained. Although only one drug ejection tube 34 is shown in FIG. 1, a plurality of drug ejection tubes may be provided.

The valve operating mechanism 35 normally pushes up the above-mentioned diaphragm 32b, whereby the valve body 33a of the valve 33 comes into contact with the medicine passage 32c, closes the medicine passage 32c, and closes the main body case 10. When a predetermined amount of washing water is taken into the inner box 11,
Any structure may be used as long as the valve body portion 33a can be separated from the medicine passage port 32c. The valve operating mechanism 35 employed in the present embodiment includes a shaft portion 35a, a flat diaphragm pressing portion 35b provided on one side of the shaft portion 35a, and a second diaphragm provided on the other side of the shaft portion 35a. And a float 35c. Then, with respect to the mounting frame 10a in which the middle part of the shaft 35a is fixed in the main body case 10, the support shaft 10b
Mounted via. As a result, the shaft portion 35a is supported by the intermediate portion supported by the support shaft 10b, and the diaphragm pressing portion 35b and the second float 35c can move up and down around the support point. In the middle part of the shaft portion 35a supported by the support shaft 10b, in a normal state, that is, in a state where the washing water is not taken into the inner box 11, the second float 35c descends, and the diaphragm pressing portion 35b rises. , The position where the diaphragm 32b can be pushed up is selected. Note that reference numeral 3
5d is a through-hole formed so as not to contact the medicine ejection pipe 34 when the diaphragm pressing portion 35b moves up and down.

In this configuration, when the cleaning water is supplied to the cleaning water supply pipe 14, the cleaning water is supplied to the cleaning water supply pipe 14.
Is supplied into the flush toilet 13 via the In addition, a part of the washing water flowing through the washing water supply pipe 14 flows into the water inflow / drainage pipe section 12 through the communication pipe 15, and the valve element provided in the water inflow / drainage pipe section 12. While not being pressed against the valve seat and being opened, the water flows through the water inflow / outflow pipe 12 and flows into the inner box 11 from the upper end of the water inflow / outflow pipe 12. The first float 17 moves upward when water flows into the inner box 11, and the valve body in the water inflow / drainage pipe section 12 is pressed against the valve seat to stop the flow of the wash water.

When the washing water is taken into the inner case 11 in this manner, as shown by the imaginary line in FIG.
While the position of the second float 35c rises, the diaphragm pressing portion 35b provided on the opposite side via the shaft portion 35a descends (from FIG. 2A to FIG. 2B).
In the state shown in the figure). As a result, the diaphragm 32b
Is lowered, and the position of the valve 33 supported by the diaphragm 32b is also lowered.
a is separated from the medicine passage port 32c. Thereby, the medicine in the medicine tank 31 is taken into the medicine dripping chamber 32 through the medicine passage port 32c.

When the supply of the cleaning water is near the end and the water pressure of the cleaning water drops, the water pressure of the cleaning water is not applied to the valve disposed in the water inlet / outlet pipe portion 12.
The valve body is separated from the valve seat, and the water inlet / outlet pipe portion 12 is opened. As described above, when the water inflow / outflow pipe section 12 is opened, the mixed liquid (drug aqueous solution) of the washing water in the inner box 11 and the medicine dropped in the inner box 11 in advance by the previous operation is removed. , Water inlet and outlet pipe 1
2 and through the communication pipe 15 to the washing water supply pipe 14 and flow down from the washing water supply pipe 14 into the flush toilet 13 (FIG. 3).
reference).

On the other hand, when the mixed liquid of the washing water and the chemical in the inner box 11 flows out and the water level in the inner box 11 starts to decrease, the second float 35c descends and becomes a fulcrum. The diaphragm pressing portion 35b ascends about the middle of the shaft portion 35a, and the diaphragm 3
2b is pushed up from below (see FIG. 2C). As a result, the valve body portion 33a of the valve 33 supported by the diaphragm 32b comes into contact with the medicine passage port 32c, and stops the outflow of the medicine from the medicine tank 31. When the water level in the inner box 11 further decreases, the diaphragm pressing portion 35b further rises.
Since a is already in contact with the medicine passage port 32c, the spring 33d disposed between the valve body 33a of the valve 33 and the diaphragm 32b is pressed and contracted, and the inside of the medicine dripping chamber 32 is compressed. Therefore, the medicine held in the medicine dropping chamber 32 penetrates into the medicine ejection pipe 34, and only a required amount is slowly dropped into the inner box 11 by the capillary phenomenon.

The flushing water is newly taken into the inner box 11 of the main body case 10, and the above-described operation of the flushing toilet chemical supply device according to the present embodiment is repeated.
As described above, since the medicine is ejected only in a required amount, excessive consumption of the medicine can be prevented even when the medicine is used continuously.

[0025]

As described above, according to the medicine supply device for flush toilet of the present invention, the medicine tank is provided with the medicine dropping chamber, and the medicine discharge pipe for discharging a fixed amount of medicine is provided. Therefore, the medicine once flows into the medicine dropping chamber from the medicine tank, so that the medicine exceeding the capacity of the medicine dropping chamber is not discharged, and the excessive supply of the medicine can be prevented. Moreover, since the medicine is supplied through the medicine discharge pipe, even when the flush toilet is used continuously, it is possible to prevent the amount of the medicine supplied from the medicine supply means from increasing more than necessary. Therefore, excessive consumption of the medicine can be prevented, and the number of times of replenishment of the medicine to the medicine tank can be reduced, which contributes to a reduction in cost associated with the work of replenishing the medicine.
