DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical supply device for flush toilets, and more particularly to a flush water supply pipe for supplying flush water to flush toilets. The present invention relates to an improvement in a medicine supply device for a flush toilet, which automatically supplies a required amount of medicine for disinfection, deodorization, cleaning, and the like to a toilet.

[0002]

2. Description of the Related Art In general, flush toilets are treated with various chemicals for the purpose of disinfection, deodorization, washing, and the like. The method of treating the chemicals varies depending on the type of flush toilet, and for example, there is a method in which the chemical is directly charged into the toilet or the flush water storage tank, and a method in which the chemical is placed in a water supply portion to the flush water storage tank.

[0003]

The need for such a chemical treatment is particularly high in toilets used by many people at stations, parks, hotels and restaurants, etc. In such a case, it is necessary to carry out a chemical exchange operation. Ease and sustainability of drug efficacy are important. For example, when a medicine is directly poured into a toilet bowl, the replacement work is easy, but the consumption of the medicine is so great that it must be replaced frequently, which is uneconomical. In addition, when pouring into the washing water storage tank, there is a problem that the work becomes frequent and it is difficult to judge when to replace the drug. There are also problems that the amount is large, which is uneconomical, and that it is difficult to supply an appropriate amount of the drug.

Further, when a medicine is placed at a water supply portion of a water storage tank, it is difficult to determine the replacement operation and replacement time of the medicine in a type in which the water storage tank is at a high place. Although no problem arises, there is a possibility that a mischievous user may perform mischief.

[0005] As described above, the conventional devices and methods for disinfecting and deodorizing flush toilets by using chemicals have various problems such as frequent and uneconomical drug replacement work. These problems were particularly acute in heavily used public toilets.

Therefore, as a solution to the various problems as described above, a flushing water supply pipe for supplying flushing water to a flush toilet has conventionally been used, and the flushing is performed each time flushing water flows into the flushing toilet. 2. Description of the Related Art A chemical supply device for a flush toilet that automatically supplies a required amount of a chemical for the purpose of disinfection, deodorization, cleaning, and the like to a toilet is known (for example, Japanese Patent Publication No. 49-2154).
No. 1).

[0007] In such a flush toilet chemical supply device, a predetermined amount of water is taken into a case from a water supply pipe for supplying flush water to the flush toilet through a nozzle and a connecting pipe by the action of a valve device with a float. Then, a drug leached from a leachable bottle stopper such as a sponge body of an inverted drug bottle disposed in the case is diluted with water taken into the case to form a drug aqueous solution, and with a decrease in internal pressure in the water supply pipe. The aqueous solution of the drug dilution is drained again into the water supply pipe through the valve chamber provided with the float-attached valve device and the connecting pipe, and then discharged into the toilet bowl.

However, since the medicine leached from the leachable bottle stopper, such as the sponge body of the inverted medicine bottle, is diluted with water taken into the case to form a medicine aqueous solution, the amount of leached medicine is constant. Therefore, a constant concentration aqueous solution of the drug cannot always be supplied. In addition, since the amount of the leached medicine is not constant, the consumption amount of the medicine in the inverted medicine bottle cannot be estimated, and there is a problem that it is difficult to manage the supply time of the medicine and the like.

In view of the above, the present invention has been made in view of the above, and is provided with a flushing device which automatically supplies a chemical for the purpose of disinfection, deodorization, washing, etc. to the flushing toilet whenever the flushing water flows into the flushing toilet. By improving the medicine supply device for toilets, the efficiency of medicine replacement has been improved, the economy has been improved, and the reliability of supplying the required amount of medicine has been improved.
The purpose is to facilitate management.

[0010]

And a top lid member having a fifth magnet disposed so that the magnetic poles facing the two magnets are different poles, and a liquid medicine mixing case including a liquid medicine filled therein, The liquid medicine discharge port has a liquid medicine container arranged so as to be able to communicate with a liquid medicine passage hole formed in the upper lid member of the liquid medicine mixing case.

[0011]

In this configuration, when the washing water is supplied to the washing water supply pipe, the washing water is supplied into the flush toilet through the washing water supply pipe. In addition, a part of the washing water flowing through the washing water supply pipe flows into the connection pipe through the communication pipe and the water inflow / drainage pipe, and flows into the space formed by the lower lid member and the upper lid member from the opening. Flow in. On the other hand, the second float is
Since the first magnet and the second magnet repel each other, the first magnet and the second magnet are located before the inflow of the washing water. Further, the fifth magnet moves downward together with the valve member under the influence of the magnetic field of the fourth magnet. Therefore, in this state, the drug solution passage hole is open, and the drug solution accumulates above the valve member.

When a predetermined amount of washing water accumulates in the space defined by the upper lid member and the lower lid member, it flows into the second float. Further, when the amount of inflow into the second float reaches a predetermined amount, the weight of the second float moves downward against the repulsive force of the first magnet and the second magnet. The fifth magnet moves upward together with the valve member under the influence of the magnetic field of the third magnet. As a result, the chemical liquid accumulated above the fifth magnet is removed from the fifth magnet.
And moves below the fifth magnet through the gap between the magnet and the inner surface of the cylindrical projection. When the amount of the washing water accumulated in the second float reaches a predetermined amount, the first float moves upward, the outlet provided in the connection pipe portion is closed by the valve body, and the inflow of the washing water is stopped. .

On the other hand, when the supply of the washing water is almost over,
When the water pressure of the cleaning water drops, the water pressure from the connection pipe side is not applied to the valve body of the first float, and conversely, the water pressure of the cleaning water accumulated in the chemical solution mixing case receives the water pressure of the connection pipe part. Away from the outlet, the washing water in the chemical mixing case reaches the washing water supply pipe through the connecting pipe, the water inflow / outflow pipe, and the communication pipe, and starts flowing down from the supply pipe to the inside of the flush toilet. The washing water flowing down here, as described below,
This is a cleaning liquid mixture of the cleaning liquid and the chemical liquid that have flowed last time remaining between the bottom surface of the lower lid member and the outlet, and the new cleaning water.

When the amount of washing water in the second float becomes large enough to withstand the repulsive force of the first magnet and the second magnet, the second float moves downward. The fifth magnet moves upward under the influence of the magnetic field of the third magnet. Therefore, a certain amount of the chemical liquid accumulated above the fifth magnet moves below it, and further, when the amount of water in the second float becomes equal to or less than a predetermined amount, the fifth magnet descends and becomes cylindrical. The liquid is dropped into the second float from the liquid discharge hole provided at the tip of the projection.

[0015] Then, the mixture with the certain amount of the chemical is
It remains on the bottom surface of the lower lid member. Next, when the washing water flows and flows into the chemical mixing case as described above,
The mixed liquid in which the certain amount of the chemical is mixed and the newly flowing washing water are mixed, and when the water pressure of the washing water further decreases, the washing mixed liquid again forms a liquid passage hole formed in the second float, The water reaches the flush water supply pipe via the connection pipe section, the water inflow / outflow pipe section, and the communication pipe, and flows down from the supply pipe to the inside of the flush toilet.

Further, on the upper surface of the upper lid member 84, a chemical solution passage hole 84a is formed so as to be able to communicate with the chemical solution discharge port 9a of the chemical solution container 9, and inward on the opposite side of the chemical solution passage hole 84a. A substantially cylindrical projection 84b is provided toward the projection. Inside the projection 84b, there is provided a valve member 84c capable of opening and closing the chemical solution passage hole 84a, and a circular fifth member connected to the valve member 84c and having a diameter smaller than the inner diameter of the projection 84b.
, And a liquid ejection hole 84e.
A cap member 84f mounted on the distal end opening of the projection 84b is provided. The diameter of the liquid discharge hole 84e is such that the liquid is not discharged from the hole when the chemical is not extruded, that is, in a normal state, and the liquid does not leak.

Here, reference numeral 10 shown in FIGS. 5 and 6 denotes another liquid medicine container filled with a liquid medicine of a type different from the liquid medicine filled in the liquid medicine container 9, and a case for mixing the liquid medicine. 8 at an appropriate position of the upper lid member 84.
It is deployed upside down via the permeable membrane 10b with a facing downward.

Next, the operation of the flush toilet device 1 will be described. The medicine supply device 1 for flush toilets is used, for example, by fixing the back surface of the base member 3 to a wall near a flush water supply pipe for supplying flush water to a flush toilet of a toilet using an adhesive tape or a screw.

When the washing water is supplied to the washing water supply pipe, the washing water is supplied into the flush toilet through the washing water supply pipe. A part of the washing water flowing through the washing water supply pipe flows into the pipe 7 through the communication pipe 6. While the valve body 82a of the first float 82 does not move upward, the washing water flowing into the pipe body 7 passes through the outlet 81e of the connection pipe section 81a through the connection hose 7b, and the lower lid member of the chemical solution mixing case 8 8
1 and into the internal space formed by the upper lid member 84.

In this state, as shown in FIG.
Of the upper cover member 8 because the first magnet 81c and the second magnet 83b repel each other.
4 is biased in a direction approaching the upper surface of the upper surface 4. Therefore, the support member 8 provided on the second float 83
Of the two magnets supported by 3g, the magnetic field of the fourth magnet 83i disposed below acts on the fifth magnet 84d. That is, the fifth magnet 84
The d moves downward in the substantially cylindrical projection 84b under the influence of the magnetic field of the fourth magnet 83i. Accordingly, the valve member 84c connected to the fifth magnet 84d
Also move down. As a result, the drug solution accumulates above the valve member 84c from the drug solution discharge port 9a of the drug solution container 9 through the drug solution passage hole 84a.

As shown in FIGS. 8 and 9, when the flow rate of the washing water exceeds a predetermined value, the washing water flows into the second float 83 from the liquid passage hole 83c of the second float 83 and the upper edge thereof. Inflow. Further, when the amount of washing water flowing into the second float 83 is equal to or more than a predetermined amount, the second float 83 is weighted against the repulsive force of the first magnet 81c and the second magnet 83b. Moves down. Thus, the fifth magnet 84d moves upward together with the valve member 84c under the influence of the magnetic field of the third magnet 83h disposed above the support member 83g of the second float 83. Then, the chemical liquid flows into a gap formed between the fifth magnet portion 84d and the cap member 84f. Since the gap is always constant, the amount of the flowing chemical is also constant.

When the washing water further flows, the float portion 82c of the first float 82 moves upward, so that the valve body 82a also moves upward, and the connecting pipe portion 81a provided on the lower lid member 81.
Is closed, and the inflow of the washing water is stopped.

On the other hand, near the end of the supply of the cleaning water,
When the water pressure of the cleaning water decreases, the water pressure of the cleaning water is not applied to the valve body 82a of the first float 82. On the other hand,
The valve element 82a is opened by receiving the water pressure of the cleaning water (mixture of the chemical liquid and the residual liquid when the previous cleaning water flowed) accumulated in the chemical liquid mixing case 8. Thereby, the mixed liquid reaches the washing water supply pipe via the pipe 7 and the communication pipe 6, and flows down from the supply pipe to the inside of the flush toilet. The mixed liquid in the second float 82 is applied to the bottom surface 8 of the second float 83.
It flows out through the liquid passage hole 83c formed in 3a (see FIG. 9). When the mixed liquid amount in the second float 83 becomes equal to or less than a predetermined amount, the second float 83 is urged upward by the repulsive force of the first magnet 81c and the second magnet 83b, and the upper cover member 84 (See FIG. 10). As a result, the fifth magnet 84d moves closer to the fourth magnet 83i,
Under the influence of the magnetic field of the fourth magnet 83i again, it moves downward in the substantially cylindrical projection 84b. Accordingly, the valve member 84c also moves downward. Therefore, a certain amount of the chemical solution accumulated between the valve member 84c and the cap member 84f is pressed by the valve member 84c and
From the liquid discharge hole 84e of 4f, the liquid is dropped into the second float 83 through the chemical liquid outlet 83f of the support member 83g of the second float 83, and mixed with the washing water.

This washing mixture flows out of the second float 83 through a liquid passage hole 83c provided in the bottom surface 83a of the second float 83, but flows through the connection pipe 81a provided in the lower lid member 81. Since the outlet 81e is opened at a certain height from the bottom surface of the lower lid member 81, when the volume of the mixed liquid becomes equal to or less than the height of the outlet 81e, it remains in the chemical liquid mixing case 8 ( (See FIG. 10).

Next, when the washing water flows into the chemical liquid mixing case 8, the washing water and the residual liquid already mixed with the chemical liquid are mixed to contain a certain amount of the chemical liquid. The washing mixture is discharged in the same manner as described above. Note that the chemical solution in the chemical solution container 9 is supplied after being temporarily accumulated in the projection 84b by the fifth magnet 84d, and is thus supplied by a constant amount until the chemical solution in the chemical solution container 9 is completely consumed.

Here, when another liquid medicine container 10 filled with another liquid medicine is provided as in this embodiment, the liquid mixture in the liquid medicine mixing case 8 contacting via the permeable membrane 10b is provided. The chemical solution leaches from the other chemical solution container 10 until the concentration of the other chemical solution container 10 and the chemical solution filled in the other chemical solution container 10 become constant. Since the mixed liquid in the chemical liquid mixing case 8 is diluted each time the washing water flows in, a certain amount of the chemical liquid is leached each time, and as described above, the connection pipe portion 81a, the pipe 7, and the communication pipe The washing water is supplied to the washing water supply pipe through 6, and the water flows down from the supply pipe into the flush toilet. When the chemical is supplied through the permeable membrane 10b, the concentration of the chemical gradually decreases. Therefore,
As the chemical liquid to be filled in the other chemical liquid container 10, it is preferable to fill the chemical liquid filled in the chemical liquid container 9 with an auxiliary liquid.

By the way, in this embodiment, the method of supplying the cleaning water to the cleaning water supply pipe is as follows.
An optical sensor 51 is provided in an opening formed in the front wall of the cleaning water supply unit, and the optical sensor 51 senses use of the sensor and supplies a valve by operating a valve mechanism (not shown) of the washing water supply pipe. I have. According to this configuration, the sensor section for supplying the cleaning water and the above-described chemical liquid supply mechanism can be housed in one case, so that the mounting operation is simplified.

Further, even when the automatic sensing type is adopted, this sensor mechanism may be provided outside the main body case 2 as a matter of course. Furthermore, a system such as a cis-tank system or the like in which a user of the flush toilet presses a push button or the like provided in the vicinity of each toilet to activate the flush water supply device or a timer or other timed device that flows at predetermined time intervals by a timer or the like. May be adopted. .

According to the medicine supply device for a flush toilet having such a configuration, a medicine for the purpose of disinfection, deodorization, cleaning, etc. is automatically supplied to the flush toilet every time the flush water flows into the flush toilet when the toilet is used. Thus, the medicine replacement workability can be improved, the economy can be improved, and the certainty of the supply of the required amount of medicine can be improved.

Therefore, the drug capacity can be maintained for a long time,
There is an advantage that it is not necessary to replenish the medicine frequently, and maintenance and management are simplified. Further, the liquid medicine in the liquid medicine container 9 is temporarily held and dropped in the projection 84b of the upper lid member 84 by the vertical movement of the fifth magnet 84d. Therefore, it is possible to reliably supply the liquid drug in a substantially constant amount, and it is possible to always supply a drug solution having a constant concentration. Further, since the amount of supplied medicine is substantially constant, there is an advantage that the consumption amount of the medicine can be estimated, and the management of the supply time of the medicine can be easily performed.

Although the present invention has been described with reference to specific embodiments, the present invention is not limited to these embodiments. It should be noted that various changes and modifications can be made without departing from the scope.

[0038]

As described above, according to the medicine supply device for flush toilets of the present invention, the medicine replacement workability can be improved.
The economy can be improved, and the certainty of supplying a certain amount of drug can be improved. In addition, since the certainty of the quantitative supply of the drug can be improved, maintenance and management can be facilitated, and it is particularly suitable for toilets of hotels and restaurants used by many people.
