Description

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 toilet whenever the flush water is supplied from the flush water supply device to the flush toilet by automatically detecting the use of the flush toilet. The present invention relates to improvement of a chemical supply device for flush toilets that automatically supplies a necessary amount of chemicals for disinfection, deodorization, cleaning, etc.

[0002]

2. Description of the Related Art Generally, flush toilets are treated with various chemicals for the purpose of disinfection, deodorization, cleaning and the like. The method of treating the medicine differs depending on the type of flush toilet, but for example, there is a method of directly introducing the medicine into the toilet bowl or the flush water storage tank, and a method of placing the medicine at the water supply site to the flush water storage tank.

[0003]

The need for such drug treatment is particularly high in public toilets such as stations and parks used by a large number of people. Sustainability is important. For example, when the medicine is directly put into the toilet bowl, the replacement work is easy, but the medicine consumption is so great that it must be replaced frequently, which is uneconomical. In addition, there is a problem that when the water is put into the wash water storage tank, the work becomes frequent and it is difficult to judge the replacement time of the chemicals. There is also a problem that the amount is large and it is uneconomical.

Further, when the medicine is placed at the water supply portion of the water storage tank, it is difficult to perform the medicine replacement work and the judgment of the replacement time when the water storage tank is located at a high place. Although no problem occurs, there is a risk that mischievous users will perform mischief.

As described above, conventional devices and methods for disinfecting and deodorizing flush toilets by using chemicals have various problems such as frequent chemical replacement work and uneconomical, These problems were particularly serious in public toilets that were used frequently.

Therefore, as a solution to the above-mentioned various problems, it has been conventionally used in combination with a flush water supply pipe for supplying flush water to the flush toilet, and the flush water is flushed each time the flush water flows through the flush toilet. There is known a chemical supply device for flush toilets which automatically supplies a necessary amount of chemicals to a toilet bowl for the purpose of disinfection, deodorization, cleaning, etc. (for example, Japanese Patent Publication No. 49-2154).
(See Japanese Patent Publication No. 1).

In such a flush toilet chemical supply device, a fixed amount of water is taken into the case from the water supply pipe for supplying flush water to the flush toilet via the nozzle and the connecting pipe by the action of the valve device with a float. Then, the drug leaching from the leachable bottle stopper such as the cavernous body of the inverted drug bottle arranged in the case is diluted with the water taken in the case to be a drug aqueous solution, and the internal pressure in the water supply pipe is reduced. Then, the diluted chemical solution is drained again into the water supply pipe through the valve chamber provided with the valve device with the float and the connecting pipe, and then discharged into the toilet bowl.

However, in such a conventional chemical supply device for flush toilet, the chemical leaching from the leaching bottle stopper such as the cavernous body of the inverted chemical bottle is diluted with the water taken in the case to form a chemical aqueous solution. With this configuration, the amount of the leaching drug is not constant, and the drug aqueous solution having a constant concentration cannot be constantly supplied. Further, since the amount of the leached drug is not constant, the consumption amount of the drug in the inverted drug bottle cannot be estimated, and it is difficult to manage the drug replenishment timing and the like.

Therefore, the present invention has been made in view of the above circumstances, and a flushing system that automatically supplies chemicals for the purpose of disinfection, deodorization, washing, etc. to the flushing bowl whenever flushing water flows through the flushing bowl. By improving the chemical supply device for the toilet bowl, it improves the chemical exchange workability, improves the economic efficiency, improves the certainty of supplying the required amount of chemicals, and maintains / retains chemicals.
The purpose of this is to facilitate management, and also to equip it with a washing water supply device integrally to improve the functionality.

[0010]

Therefore, the chemical supply device for flush toilet of the present invention has an inlet communicating with the water supply source at one end and an outlet communicating with the inside of the flush toilet at the other end. A flush water supply control unit including a flush water supply passage, an opening / closing valve that is interposed in the flush water supply passage to open and close the passage, and an opening / closing mechanism for the open / close valve, and automatically detects use of a flush toilet And a control means for controlling the opening / closing mechanism to open the opening / closing valve based on a detection signal output from the sensing means. A main body case having a supply device, a water inflow / outflow pipe portion communicating with a wash water supply path downstream of the outlet, and a chemical solution mixing case housed inside the main body case, Equipped with a connecting pipe part that is connected to the inflow and exhaust pipe parts A lower lid member, an outflow port through which water flows out from the connection pipe section, a first float including a valve body capable of closing the outflow port, and a first magnet provided on the lower lid member, A bottomed tubular second float having a liquid passage hole formed on the bottom surface and having a second magnet fixed so that the same pole surface faces the first magnet;
Third and fourth magnets, which are supported by a support member provided upright on the bottom surface of the second float, and are fixedly arranged so that the different poles face each other at regular intervals, and a chemical solution passes through on the upper surface. A substantially cylindrical projection having a hole formed therein and protruding inward from the upper surface and having a liquid discharge hole at the tip, and movably supported in the projection to open and close the chemical solution passage hole. A fifth member arranged so that the magnetic poles opposed to the valve member and the magnets that are connected to the valve member and are located near the middle of the third magnet and the fourth magnet have different polarities. An upper lid member having a magnet, and a liquid medicine mixing case configured to include the liquid medicine inside, so that the liquid medicine discharge port can communicate with a liquid medicine passage hole formed in the upper lid member of the liquid medicine mixing case. And a chemical solution container provided The features.

Further, in the above-mentioned chemical supply device for flush toilet, a chemical liquid supply hole for supplying another liquid chemical to the upper lid member of the chemical liquid mixing case is opened, and another chemical liquid supply hole is provided in the chemical liquid supply hole via the permeable membrane. The liquid medicine container filled with the liquid medicine is attached.

[0012]

In this structure, when the use of the flush toilet is detected by the sensing means, the opening / closing mechanism is controlled to open the opening / closing valve based on the sensing signal output from the sensing means, and the flush water supply passage is opened. Wash water is supplied into the flush toilet via the above. In addition, a part of the wash water flowing through the wash water supply path downstream of the outlet flows into the connection pipe portion through the water inflow / outflow pipe portion and enters the space formed by the lower lid member and the upper lid member from the opening. Pour in.

On the other hand, since the first magnet and the second magnet repel each other, the second float is located above before the inflow of washing water. Further, the fifth magnet moves downward together with the valve member due to 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 collects above the valve member.

When a predetermined amount of cleaning water accumulated in the space formed by the upper lid member and the lower lid member reaches the second float. When the amount of wash water accumulated in the second float reaches a predetermined amount, the first float moves upward, and the valve body closes the outlet provided in the connecting pipe portion to stop the inflow of wash water. .

On the other hand, when the supply of washing water is almost over,
When the water pressure of the wash water decreases, the water pressure from the connection pipe side is no longer applied to the valve body of the first float, and conversely, the water pressure of the wash water accumulated in the chemical solution mixing case is received and the flow of the connection pipe part flows. After leaving the outlet, the washing water in the chemical solution mixing case reaches the washing pipe through the connecting pipe portion and the water inflow / outflow pipe portion, and starts to flow down from the washing pipe to the inside of the flush toilet. The washing water flowing down here is, as described below, a mixture of the previously flowing washing water and the chemical liquid remaining between the bottom surface of the lower lid member and the outlet, and this new washing water. It is a washing mixed solution with.

When the amount of washing water in the second float becomes a weight that cannot withstand the repulsive force between 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. As a result, the chemical solution accumulated above the fifth magnet passes through the gap between the fifth magnet and the inner surface of the cylindrical protrusion and moves below the fifth magnet. On the other hand, the mixed liquid in the second float is
Out through the liquid passage hole formed on the bottom surface of the float. When the amount of the mixed liquid in the second float becomes equal to or less than a predetermined amount, the second float is urged upward by the repulsive force of the first magnet and the second magnet. As a result, the fifth magnet moves closer to the fourth magnet, and moves downward due to the influence of the magnetic field of the fourth magnet. Therefore, a certain amount of the chemical liquid accumulated under the fifth magnet is dripped into the second float through the liquid discharge hole provided at the tip of the cylindrical protrusion.

Then, the mixed solution with a certain amount of the chemical solution is
It remains on the bottom surface of the lower lid member. Next, when the washing water flows in and flows into the chemical solution mixing case as described above,
When the mixed liquid in which the predetermined amount of the chemical liquid is mixed and the newly introduced cleaning water are mixed, and the water pressure of the cleaning water further decreases, the cleaning liquid mixture again forms the liquid passage hole formed in the second float, It reaches the washing pipe through the connecting pipe portion and the water inflow / outflow pipe portion, and flows down from the washing pipe to the inside of the flush toilet.

It is placed upside down with the a facing downward through the osmotic membrane 10b.

Next, the operation of the flush toilet bowl chemical supply device 1 thus constructed will be described. The flush toilet chemical supply device 1 is used, for example, by fixing the back surface of the base member 3 to the wall surface just above the flush toilet of the toilet using an adhesive tape, a screw, or the like. Then, in a state where the water supply source and the inlet pipe portion 62d of the main body case portion 62a of the wash water supply controller 62 are connected, water flows from the inlet pipe portion 62d into the space portion 64a,
This water reaches the space 64c through the communication port 64b opened by the water stop valve 65, and from the valve lower end side space b of the piston valve 61a of the water supply valve 61 through the small hole 61f to the upper end side space a. The fluid flows to the upper end side space a, flows to the pipe portion 62b, and stops before the valve body of the closed solenoid valve 62c.

In such a state, the piston valve 61
Since a is biased in the valve closing direction by the elastic force of the spring 61c and a predetermined water pressure is applied to the valve upper end side space portion a, it is kept closed. In this state, the communication port 64d is closed by the piston valve 61a, and the water flowing into the space 64c of the main body case 62a does not flow into the cleaning pipe 6.

Next, when the user is located in front of the optical sensor 51 and leaves after using the flush toilet,
Since the light is cut off for a predetermined time from the state where the optical sensor 51 senses the light, the controller 52 energizes the solenoid valve 62c from the lithium battery 53 and causes the solenoid valve 62c to switch its valve body to the valve body. Drive to open. As a result, the pipe portion 62b is opened, and the water stopped at the valve body front position of the solenoid valve 62c flows to the outlet pipe portion 62e through the space portion 64e. As a result, the water in the valve upper end side space portion a is also discharged, and the water pressure in the valve upper end side space portion a decreases, so that the piston valve 61a resists the elastic force of the spring 61c by the water pressure in the valve lower end side space portion b. Then, the communication port 64d is opened. As a result, water is supplied from the water supply source to the space 64a and the space 64 of the main body case 62a.
It is supplied to the flush toilet via the washing pipe 6 from the outlet pipe 62e through the space c and the space 64e.

The energization time to the solenoid valve 62c is selectively set by the timer, and the energization from the lithium battery 53 to the solenoid valve 62c is cut off after a predetermined time, so that the solenoid valve 62c closes the valve body. To return to the initial state,
The supply of water to the cleaning pipe 6 is cut off.

On the other hand, when the cleaning water is supplied to the cleaning pipe 6 as described above, part of the cleaning water flowing toward the cleaning pipe 6 flows into the pipe body 7 from the connector pipe 62f. While the valve body 82a of the first float 82 does not move upward, the cleaning water that has flowed into the pipe body 7 passes through the outlet 81e of the connecting pipe portion 81a through the connecting hose 7b and the lower lid member of the chemical liquid mixing case 8. 81
And the upper lid member 84.

In this state, as shown in FIG.
In the float 83, since the first magnet 81c and the second magnet 83b repel each other, the upper lid member 8
4 is urged in a direction approaching the upper surface of No. 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 arranged below acts on the fifth magnet 84d.

That is, the fifth magnet 84d is affected by the magnetic field of the fourth magnet 83i and moves downward in the substantially cylindrical projection 84b. Along with this, the valve member 84c connected to the fifth magnet 84d also moves downward. As a result, the drug solution is accumulated on 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 FIG. 10 and FIG. 11, when the inflow amount of the cleaning water becomes a predetermined value or more, the cleaning water flows into the second float 83 from the liquid passage hole 83c of the second float 83 and its upper edge. Inflow. Furthermore, this second float 83
When the amount of wash water flowing in exceeds a predetermined amount, the second float 83 moves downward due to its weight against the repulsive force between the first magnet 81c and the second magnet 83b. As a result, the fifth magnet 84d is affected by the magnetic field of the third magnet 83h disposed above the support member 83g of the second float 83,
It moves upward together with the valve member 84c. Then, the chemical liquid flows into the gap formed between the fifth magnet 84d and the cap member 84f. Since this gap is always constant, the amount of chemical liquid flowing in is also constant.

When the wash water further flows in, 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.
The opening 81e formed in the is closed and the inflow of washing water is stopped.

On the other hand, near the end of the supply of washing water,
When the water pressure of the wash water decreases, the water pressure of the wash water is not applied to the valve body 82a of the first float 82. On the other hand,
The valve body 82a is opened by receiving the water pressure of the cleaning water (mixed liquid of the residual liquid mixed with the chemical liquid when the cleaning water last flowed) accumulated in the chemical liquid mixing case 8. As a result, the cleaning water in the chemical solution mixing case 8 separates from the outlet of the connection pipe portion 81a, and the cleaning liquid in the chemical liquid mixing case 8 reaches the cleaning pipe 6 through the pipe body 7, and the cleaning liquid Flow down from the pipe 6 to the inside of the flush toilet bowl. The mixed liquid in the second float 83 is
Liquid passage hole 83 formed in the bottom surface 83a of the float 83
It flows out through c (see FIG. 11). Second float 8
When the amount of the mixed liquid in 3 becomes a predetermined amount or less, the repulsive force between the first magnet 81c and the second magnet 83b causes
The second float 83 is biased upward, and the upper lid member 84
Moves up until it abuts the inside of the upper surface (see FIG. 12). As a result, the fifth magnet 84d comes close to the fourth magnet 83i, so that the fourth magnet 8d is again moved.
Under the influence of the magnetic field of 3i, it moves downward in the substantially cylindrical protrusion 84b. Along with this, the valve member 84c also moves downward. Therefore, the valve member 84c and the cap member 84f
From the liquid discharge hole 84e of the second float 8 through the chemical liquid outflow portion 83f of the support member 83g of the second float 83.
It is made to drip into 3 and is mixed with washing water.

The cleaning mixture flows out of the second float 83 through the liquid passage hole 83c provided on the bottom surface 83a of the second float 83, but flows through the connection pipe portion 81a provided on 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 lower than the height of the outlet 81e, the mixed liquid remains in the chemical liquid mixing case 8 ( (See FIG. 12).

Next, when the washing water flows into the chemical liquid mixing case 8, the washing water and the residual liquid in which the chemical liquid has already been mixed are mixed to contain a certain amount of the chemical liquid. The washing mixture is allowed to flow out in the same manner as described above, and the washing mixture containing a certain amount of the chemical solution is caused to flow out in the same manner as described above. Since the chemical solution in the chemical solution container 9 is temporarily stored in the protrusion 84b by the fifth magnet 84d and then supplied, the chemical solution in the chemical solution container 9 is always supplied in a constant amount until it is completely consumed.

Here, when another liquid medicine container 10 filled with another liquid medicine is arranged as in the present embodiment, the mixed liquid in the liquid medicine mixing case 8 in contact with the other side through the permeation membrane 10b. The chemical liquid leaches from the other chemical liquid container 10 until the concentration of the chemical liquid filled in the other chemical liquid container 10 becomes constant. Since the mixed solution in the chemical solution mixing case 8 is diluted each time the cleaning water flows in, a certain amount of the chemical solution is leached out each time, and as described above, via the connecting pipe portion 81a and the pipe body 7. It reaches the washing pipe and flows down from the washing pipe to the inside of the flush toilet. When the chemical solution is supplied through the permeable membrane 10b, the chemical solution concentration 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 which fills the chemical liquid container 9 and plays an auxiliary role.

According to the medicine supply device 1 for flush toilet having the above-mentioned structure, every time flush water flows through the flush toilet when the toilet is used, the medicine for disinfecting, deodorizing, cleaning, etc. is automatically supplied to the flush toilet. Therefore, it is possible to improve the workability of exchanging the medicine, improve the economical efficiency, and improve the certainty of supplying a necessary amount of the medicine. Therefore, there is an advantage that the drug capacity can be maintained for a long period of time, the drug does not need to be replenished frequently, and the maintenance and management are simplified.

Further, the fifth magnet 84d is vertically moved so that the chemical solution in the chemical solution container 9 is once held in the projection portion 84b of the upper lid member 84 of the chemical solution mixing case 8 and dropped. Therefore, the liquid medicine can be reliably supplied in a substantially constant amount, and the medicine aqueous solution having a constant concentration can be constantly supplied.
Further, since the amount of the drug supplied is substantially constant, the consumption amount of the drug can be estimated, and there is an advantage that it becomes easy to manage the drug replenishment timing and the like.

Further, in the flush toilet chemical supply device 1 having such a structure, the use of the flush toilet is detected by the optical sensor 51 inside the main body case 2 and the water supply valve 61 is opened to operate the flush toilet. Since the flush water supply device 60 for supplying flush water to the toilet is integrated, it is not necessary to install the flush water supply device separately from the flush toilet chemical supply device 1, and the flush water supply device is used as the flush toilet. Compared to the case where both the chemical supply devices are separately provided, the installation work of the devices is simplified and the cost is also improved.

Further, since the flush water supply device can be compactly housed as compared with the case where both the flush toilet chemical supply device is provided separately, the flush toilet can be installed without taking up a lot of installation space around the flush toilet. The toilet bowl area will not be complicated and will be clean, and the image of the toilet space can be kept good.

Since the flush water supply device 60 is constructed so as to detect the use of the flush toilet and automatically flush the flush toilet, there is no need for manual operation for washing, and there is a need for manual operation. Since it does not forget to operate, it is hygienic because it is washed surely after each use. Further, since the optimum flow rate required for cleaning the toilet bowl is supplied each time it is used, there is an advantage that wasteful water is not consumed.

Although the present invention has been described with reference to a specific embodiment, the present invention is not limited to this, and a person skilled in the art can obtain the claims attached to the present invention. It should be noted that various changes and modifications can be made without departing from the scope.
