[Industrial applications]

 The present invention relates to a flush toilet chemical supply device for branching the flush water pipe and supplying chemicals for flush toilets.

[0002]

[Prior art]

 In a device that is installed in a branch to the flush water pipe and controls the outflow of water by a float valve and supplies the toilet cleaning agent, it is necessary to make the supply amount of the agent constant. Kaihei 3-66842 proposes a drug container in which a measuring container and a siphon are used together. However, in this device, the structure is complicated and the device is large. Further, Japanese Patent Application Laid-Open No. 3-59236 proposes a drug device having an upper part sealed with a stopper and having a discharge port at the lower part of the side wall. Since the container is sealed, it is inconvenient to replenish the drug, and if foreign matter such as solidified drug is sandwiched between the stopper and the container, the hermeticity will be lost and the quantitative supply of the drug will be insufficient.

[0003]

[Problems to be solved by the device]

 The inventors have studied the structure of a drug supply device that uses a solid drug that is easy to handle as a drug and that has a simple structure and can ensure quantitativeness.The solid drug has a constant contact area with a certain amount of cleaning water for a certain period of time. We thought that it would be good if we could hold it, and conducted repeated examinations to complete this proposal.

[0004]

[Means for Solving the Problems]

 According to the present invention, the main body container, the float valve provided at the bottom of the main body container, the chemical container contained in the main body container, and the water supply / drain pipe connectable to the flush water pipe, the chemical container being water floatable. In addition, there is provided a drug supply device characterized in that a drug discharge port is provided at the bottom of the container. An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a main body container 1 accommodates a drug container, forms a toilet flushing solution by flushing water, and supplies a flushing solution to a flush water pipe. There is no particular limitation. A valve chamber 3 of a float valve 4 is provided at the bottom of the body container, and a float 6 is attached to the upper end of the valve body of the float valve. The main body container is connected to the water supply / drainage pipe 2 via a float valve, and the water supply / drainage pipe is connected to the flush water pipe.

The drug container 8 is buoyant in water and has a structure in which the container itself holds buoyancy to store a solid (including gel-like) drug and the lower part of the drug comes into contact with water. Of course, the shape of the container is, for example, a cylindrical shape with the central part as a drug accommodating portion shown in the perspective view and sectional view of FIG. 2A, and a disk shape with a large number of water guiding holes shown in the perspective view of FIG. 2B. , (C) is a raft shape with parallel rectangular buoyancy bodies on both sides shown in the perspective view, (D) is a circular dish shape with the central part as a drug container shown in the perspective view and cross-sectional view, (E) Shown in a perspective view and a cross-sectional view The above (D) is an upside down circular plate-like shape, and (F) is a perspective view and a cross-sectional view. A discontinuous foam or a hollow body with a gas inside can be used. The shape and volume are appropriately determined according to the weight of the drug used. It is preferable that the drug container has a buoyancy such that usually 50% or more, preferably 90% or more of the drug is above the water surface in a state where the drug is most closely packed in the drug container. A guide pole or an enclosure shown in FIG. 3 may be provided in the main body container so as to prevent the drug container from being overturned or prevent the drug container from coming into contact with the float of the float valve and impeding the function of the float. Further, as shown in FIG. 4, the float of the float valve may be used as the buoyant body of the medicine container and the peripheral portion thereof may also be used as the medicine container. The drug discharge port is provided in the lower part of the drug container, and specifically, is provided in the bottom part or the lower part of the side wall of the drug container. A slit, a mesh, a hole, a non-woven fabric or a woven fabric, an open-cell foam, or the like is used for the drug discharge port 7 of the drug container, and the number and material thereof are determined according to the type of drug used. The top of the drug container is usually open. The medicine can be supplied through this opening. The opening may have a lid.

As the drug, a urinary stone preventive agent, an aromatic agent, a cleaning agent, an antiscalant agent, a disinfectant agent, a disinfectant agent, etc. are used, and a solid cylindrical or ring-shaped block or granular material is preferably used. It Drugs are stacked or filled in drug containers. The drug is dissolved and released from the lower part of the drug. Since the new drug supplied from the upper part moves to the lower part in sequence, the amount of drug released can be kept constant. As shown in FIG. 5, the water supply / drainage pipe of the drug supply device of the present invention can be compactly connected by connecting with a fitting pipe to the push button mounting port of the flush valve of the flush water pipe. This is advantageous in the case of actuated valves. Further, the joint pipe may have a structure which also serves as a push button as shown in FIG.

[0007]

[Action]

 The device of the present invention is used by branching from the middle of the flush water pipe connecting the flush valve and the toilet. When the flush valve opens and flush water flows, much of the water flows to the toilet bowl. Part of the water flows into the main body container of the device of the present invention through the water supply / drain pipe and the valve chamber. When water flows into the main container, the float floats and the float valve rises. At this time, the water-buoyant drug container floats up due to the water flowing into the main body container. Since the bottom or bottom of the drug container is submerged in water, water flows into the drug container through the drug discharge port, the drug dissolves, and spreads in the main container. When the amount of water in the main body container reaches a certain amount after a certain time, the float valve closes and the flow of water into the main body container stops. Then, when the flush valve is closed and the flow of flush water is stopped, the pressure in the valve chamber is lowered and the float valve is opened, and the water in which the drug is dissolved flows out through the water supply / drain pipe to the flush water pipe to supply the drug. The time until the drug solution in the main body container finishes flowing out is constant, and therefore, while the drug solution is flowing out of the main body container until the water flows into the main body container, the drug contained in the drug container remains It dissolves in water. The drug container is designed to have a buoyancy of 50% or more, preferably 90% or more of the drug in a state that the drug is most closely packed in the drug container. The increase in buoyancy of the drug container due to the decrease in gravity has almost no effect on the area where the drug in the drug container floating in water comes into contact with water, and the contact area is almost constant during the above period and is supplied to the toilet bowl. The amount of drug delivered is constant.
