Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a toilet flushing device equipped with equipment that automatically supplies and flows a chemical solution into the water stored in the tank body.

``Prior art'' Recently, a chemical solution such as a deodorizing solution or a cleaning solution is mixed into the water stored in a flushing tank, and when the toilet is used, the flush water mixed with the chemical solution is discharged into the toilet bowl to eliminate odors and flush the toilet. A method of cleaning is used.

As a conventional toilet flushing device of this type, one is known in which a container body containing a chemical solution is hung upside down inside the tank body, and the chemical solution is mixed into the tank body by utilizing the increase and decrease in the amount of water stored in the tank body. .

``Problems to be solved by the invention'' Since the above-mentioned conventional device suspends a chemical container inside the tank, the size of the container is limited in order to maintain a constant amount of water stored in the tank. Therefore, due to the miniaturization of the container body, the number of refills of the drug solution into the container body increases, and it is necessary to open the tank body each time the drug solution is refilled, which is troublesome.

In view of the above-mentioned disadvantages, this design is for toilets that solves the above-mentioned inconvenience by suspending a chemical solution container outside the tank and automatically supplying and mixing an appropriate amount of chemical solution into the tank body in conjunction with water discharge when using the toilet. The purpose is to provide a water washing device.

“Problems that the invention attempts to solve” Toilet flushing tank device and chemical solution storage device 1
0, and a suction pipe 9 that communicates these two devices, and the tank device has a top wall 2 having a concave upper surface.
It has a fitting conduit 5 in which one end of the suction pipe is fitted into the central through hole of the body, and a water discharging device in which a suction nozzle 4 having a hand washing water supply conduit 6 around the fitting conduit is fitted. The drug solution storage device 10 includes a container body 12 containing a drug solution fixed in an inverted state with its mouth and neck protruding downward, and a hand wash water supply faucet 3 for supplying water into the recess. The suction pipe 9 is attached to the mouth of the container body, and is formed by a saucer 15 that drains the medicinal solution inside the container by automatically replacing the medicinal solution inside the container with outside air and stores the spilled medicinal solution.
The other end is inserted into the stored chemical solution in the saucer through the chemical liquid surface, and the water in the tank body 1 is reduced by using the water discharge device, and the water discharged from the water supply faucet 3 blocks the water supply pipe 8. By creating a negative pressure inside the tank body, the suction pipe 9 was formed to be able to suck out the medicinal liquid in the saucer 15 into the tank body 1.

"Operation" When the water spraying device of the tank body 1 is activated from the state shown in FIG. 1, the water stored in the tank body 1 decreases due to the water discharge, and the water level drops. On the other hand, at the same time as the water is being discharged, water supply into the tank body is also started, and a portion of the supplied water is poured out from the hand wash water supply faucet 3 into the recess on the upper surface of the top wall of the tank body. The supplied water flows down into the tank body 1 through the water supply pipe 8 on the top wall of the tank body, but since the amount poured into the recess is larger than that of the flowing water, it is temporarily stored in the recess. The Rukoto.

Due to the drop in the water level inside the tank body 1 and the water stored in the recess, the pressure inside the tank body 1 becomes negative.
By making the pressure negative, the inside of the suction pipe 9 is also made negative, and the chemical solution in the saucer 15 is sucked out into the tank body 1.

As shown in FIG. 2, when the liquid level in the saucer 15 decreases and the liquid level falls below the small hole 13 of the stopper 14, outside air flows into the container body 12 through the slit 17 and the small hole 13, and the outside air Due to this replacement, the medicinal solution in the container flows into the receiver tray 15, and continues to flow into the receiver tray 15 until the small hole 13 is again closed by the liquid level and the flow of outside air into the container body is stopped.

When the discharge of the water stored in the tank body 1 is completed, the water outlet is automatically closed, and the water level in the tank body rises due to the water supply described above. Before and after the water level rises, the negative pressure inside the tank is eliminated, and therefore, the suction of the chemical solution by the suction pipe 9 is also stopped. Furthermore, when the water storage in the tank body is completed, the water supply to the tank body also stops, and therefore the water in the recessed part of the top wall of the tank body disappears, and outside air flows through the fitting pipe 5 into the upper part of the tank body and into the suction pipe 9. flows in and returns to the state shown in FIG.

Embodiment The device of the present invention includes a toilet flushing tank device, a chemical solution storage device, and a suction pipe that communicates these two devices.

First, to explain the tank device, 1 is a tank body that stores water to be discharged into the toilet bowl.The top wall 2 has a deep spherical recess in the center, and above it is a water faucet 3 for supplying water for hand washing. Although not shown in the figure, there is a water outlet with an on-off valve at the bottom, and an operating section on the side for controlling the water discharge from the water outlet to the toilet bowl and the water supply from the water faucet into the tank body.

A suction nozzle 4 is provided to pass through the central recessed portion of the top wall 2 in an airtight manner. This suction nozzle 4 has a double pipe structure, inside and outside, with the central pipe connected to the fitting pipe 5 for the suction pipe, and the outer ring-shaped pipe connected to the water supply pipe 6.
The upper outward flange 7 is placed against the upper surface of the top wall 2, and the two protrusions 8, 8 on the outer circumferential surface are brought into pressure contact with the circumferential surface of the through hole in the top wall 2 to maintain airtightness. There is. The fitting conduit 5 has an upwardly stepped portion with a portion of its lower part thickened inwardly so that one end of the suction pipe 9 can be inserted and locked therein. Of course, although not shown in the drawings, both conduits 5 and 6 are integrally formed by members provided at appropriate intervals in the circumferential direction.

The chemical liquid storage device 10 is provided above the tank body 1, and a stopper 14 having a small hole 13 in the center is liquid-tightly connected to the mouth of a container body 12 containing a chemical liquid 11 such as a deodorizing liquid or a cleaning liquid. The container body 1 is sealed, and the container body 1 is sealed so as to maintain an appropriate distance between the stopper 14 and the bottom wall of the saucer.
A cap-shaped saucer 15 is screwed onto the mouth and neck of the cap 2 and placed in an inverted position as shown in the figure. The saucer 15 is provided with a vertical slit 17 in a part of the peripheral wall 16 that stands up from the bottom wall, and is also integrally provided with a shallow cup-shaped external small chamber 18 that communicates with the inside of the peripheral wall 16 through the slit 17. The other end of the suction pipe 9 is inserted into the hole. The upper end of the peripheral wall of the small chamber 18 is made to stand higher than the small hole 13. The same applies to the slit 17, and in short, when the container body is in the inverted state shown in the figure, the medicinal liquid in the container flows down into the saucer 15, and the liquid level closes the small hole 13, thereby stopping the flow into the saucer 15. Moreover, when the medicinal liquid in the saucer 15 decreases and the liquid level falls below the small hole 13, the slit 17 and the small hole 1
It is sufficient that the outside air enters the container body through 3, and the medicinal liquid in the container flows down into the receiver tray 15 instead, and continues until the liquid level closes the small hole 13 again. Therefore, the aforementioned stopper 14 is not necessarily necessary.
If the stopper 14 is not provided, the peripheral wall of the small chamber 18 and the upper end of the slit 17 may be positioned above the lower end of the mouth and neck of the container body in the inverted state.

The suction pipe 9 has one end fitted into the fitting pipe 5 in a watertight manner as described above, and the other end fitted into the small chamber 1.
8. Insert into the stored drug solution from above through the drug solution surface. In other words, by positioning a part of the suction pipe above the chemical liquid level in the saucer 15, the suction pipe is moved to the saucer 15 only when the inside of the suction pipe becomes negative pressure.
It is provided so that the chemical solution in 5 can be sucked out into the tank body 1.

``Effect of the invention'' The present invention has the above-mentioned configuration, and is formed by a tank device for toilet flushing, a chemical solution storage device 10, and a suction pipe 9 that communicates these two devices. It can be installed outside the body, and therefore there is no need to open the tank each time the drug solution container is replaced or refilled, and the container can be placed outside the body. The amount of water stored in the tank does not change depending on the size of the body, and when the water stored in the tank is discharged, the inside of the tank 1 can be flushed using the hand washing water supplied from the faucet 3 to the tank 1 at the same time. Since the pressure is made negative and the medicinal solution in the saucer 15 of the medicinal solution storage device 10 is sucked out into the tank body 1 using the negative pressure, medicinal solution 11 is automatically supplied into the tank body 1 each time the toilet is used. It's convenient to do. In addition, the suction nozzle 4 does not require a complicated control mechanism and has a simple structure, and the saucer 1 has a simple structure although it is somewhat modified.
5 is all that is needed, and therefore there is almost no risk of failure, no troublesome maintenance is required, and the device has the advantageous effects of being inexpensive and having a long life.
