Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a chemical addition device in a flush toilet for mixing a urinary stone inhibitor or other chemicals into the flush water of the flush toilet.

(B) Conventional technology Conventionally, a container having a large number of holes instead of sana and containing a urinary stone preventive agent or other chemicals is fitted so that the cleaning water gradually dissolves the chemicals. I have already proposed what I did.

(C) Problems to be Solved by the Invention The method of fitting the container in which the urinary stone preventive agent or the like is fitted into the mounting position of the sana requires an operation of removing the container with urine adhered when the container is replaced. In addition, since a large amount of washing water flushes away urinary stone inhibitors, etc., a large amount of wasted waste is required and a solid drug is easily dissolved in order to secure a desired concentration. If so, there is a problem that it dissolves rapidly, and if it becomes difficult to dissolve, the concentration of the chemical agent in the wash water remaining in the trap will decrease and the desired effect cannot be obtained. There were problems such as.

(D) Means for Solving the Problems In the present invention, a medicine container is attached to a water supply pipe of a toilet bowl, and a water passage lid having a plurality of holes is detachably attached to at least an upper part of the medicine container, The pipe can be provided with an inflow hole communicating with the upper water lid and an outflow hole communicating with the bottom plate so that the medicine can be replenished in a clean state and the amount of water contacting the medicine can be reduced. In addition, the outflow timing of the solution was delayed to solve the above-mentioned problems.

(E) Action After putting the medicine in the medicine container, fit the water lid.

When the wash water is discharged after urinating, a part of it flows out from the inflow hole of the water supply pipe to the water passage cover and is dispersed, and then it flows into the drug container through multiple holes and gradually dissolves the drug. Then, this solution flows into the water supply pipe from the outlet hole with a delayed timing.

Therefore, the drug is hardly dissolved in the wash water flowing down in the toilet in the initial stage, and the cleaning is performed exclusively, and at the end, the solution flows through the outlet and the trap after flowing down in the urinal, Lastly, a solution with a substantially predetermined concentration that flows out is prevented from staying in the trap to generate urinary stones, or, if the drug is other, a corresponding drug effect is exhibited.

(F) Embodiments An embodiment of the present invention will be described with reference to the drawings, in which 1 is a urinal, a water supply pipe 5 having a valve 3 with a push button 2 is connected to an upper inlet, and a lower drain is connected. A drain pipe 7 having a trap 6 is connected to the outlet.

Then, a part of the water supply pipe 5 is cut off, and a diversion pipe 8 is interposed in the cut portion.
A main portion 8a having a smaller inner diameter and a larger outer diameter, and an upper connecting portion 8b and a lower connecting portion 8c fitted to the outer peripheral portion of the water supply pipe,
A conical tubular tongue piece 10 is projected on the inner circumference of the upper end of the main portion 8a, and a tapered tongue piece 11 that is narrowed downward is projected on the lower part, and is formed on the inner circumferential surface of the upper part of the lower connecting portion 8c. Is a circular ridge with a V-shaped cross section
12 is provided and the lower part is expanded.

The drug container 13 is composed of a bottom plate 13a and side plates 13b.
The central hole of 13a is fixed to the upper outer periphery of the lower connecting portion 8c,
In a plan view, it has an appropriate shape such as a rectangle or a semicircle, or an ellipse, and the bottom plate 13a is fixed with a receiving plate 16 having a large number of holes 15 ... 13b
It is detachably mounted on the rib protruding on the inner circumference.
A rib 18 and a main part 8 projecting near the upper part of the inner peripheral surface of the side plate 13a by inserting a urinary stone preventive agent 17 in the form of a tablet into the 16 ...
A water passage lid 21 having a plurality of holes 20 is mounted on the rib 19 projecting from the outer periphery of the upper part of a so that it can be inserted and removed.

On the left and right of the upper part of the flow dividing pipe 8, one to two or three inflow holes 22 are provided to connect the upper surface of the base of the tongue 10 and the upper surface of the water passage lid 21 to the left and right. , 1-2 on the left and right
Individual outflow holes 23 ... Are drilled.

In the flow dividing pipe 8, the main portion 8a, the upper connecting portion 8b, and the lower connecting portion 8c are separately molded with vinyl chloride or other synthetic resin, and at that time, circular projections that fit inside and outside of these connecting portions are projected. It is advisable to install them, fit them, and bond them with an adhesive.

Next, the operation will be described. When the push button is pressed after urination, the valve 3 is opened for a certain period of time, and the flush water flows down the water supply pipe 5 to wash the urinal 1, and the discharge pipe 7 through the trap 6 and the discharge pipe 7. Outflow to.

At this time, part of the wash water that has flowed down is diverted by the tongue piece 10 and flows into the water passage lid 21 from the inflow hole 22, spreads over the water passage lid 21, and leaks from each hole 20 ... To dissolve the drug,
The solution flows down from the holes 15 of the receiving plate 16 onto the bottom plate of the medicine container 13.

In this state, the wash water flowing down in the diversion pipe 8 is squeezed by the tapered tongue piece 11 and immediately below the tongue piece 11 is formed into an open space, so that suction force is generated in the vicinity of the tongue piece 11. ,
As a result, the solution on the bottom plate 13a of the medicine container 13 is sucked and flows into the lower part of the water supply pipe 5, so that the cleaning water is mainly washed at the initial stage of outflow, and the solution of the medicine is mixed at the final stage. Since it adheres to the discharge port and stays in the trap 6, urine stones can be prevented from being generated in the vicinity thereof.

Further, when replenishing the medicine, the water passage lid 21 is pulled up, the tablet medicine is put into the medicine container 13, and the water passage lid 21 is closed, but when one side of the water passage lid 21 is hinged, it is opened and closed. If a groove is provided on one side to make it slidable, insert and remove it.

Further, if the bottom plate 13a of the drug container 13 is formed in a funnel shape, the solution will more easily flow into the lower connecting portion 8c.

Further, when the receiving plate 16 is made detachable, the bottom of the container can be easily cleaned. Further, the numbers or the diameters of the holes 20, 15, the inflow holes 22, and the outflow holes 23 are appropriately changed depending on the solubility of the medicine, the flow rate of the washing water and other factors.

Although the medicine container 13 surrounds the water supply pipe 5 in the above-mentioned embodiment, it may be arranged so as to project from the water supply pipe to any one other than the wall side, and the holes 20 ... The cleaning water flowing from the inflow hole 22 flows into the whole of the medicine container 13 substantially uniformly by reducing the diameter of the one near 5 or increasing the interval.

Further, the outflow of the solution can be further delayed by reducing the size of the holes 20 or 15 or by using other outflow suppressing means.

(G) Effect of the Invention According to the present invention, as described above, the medicine container 13 is attached to the water supply pipe 5 of the toilet bowl, and the plurality of holes 20 are provided at least in the upper part of the medicine container 13.
The water supply lid 21 having the
The bottom plate 13a and the inflow hole 22 communicating with the upper water passage lid 21.
Since the outflow hole 23 communicating with the upper side is formed, the medicine can be replenished in a clean state, and the amount of washing water in contact with the medicine can be limited to prevent the medicine from being rapidly dissolved. Further, the separated wash water bypasses the inside of the container in order to dissolve the drug, so that the solution merges with the wash water flowing down in the diversion pipe 8 with a delay, so that the solution is relatively high at the end of the wash. A solution having a concentration can be retained in the trap 6 to effectively act the drug.
