Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a toilet bowl cleaning tank device, and more particularly to an auxiliary water supply structure for the device.

(B) Conventional technology Conventionally, in order to replenish the decrease in sealing water in the toilet bowl that occurs during the toilet cleaning operation after toilet, and to secure a certain sealing surface, the water is sealed through the overflow pipe provided in the tank. There is a toilet bowl cleaning tank device that can supply auxiliary water into the toilet bowl.

FIG. 4 shows a form A of the toilet bowl cleaning tank device according to FIG.

In the figure, 11 is a tank in which a fixed amount of washing water W is stored, and the tank 11 has a drain valve 12 at the bottom thereof.

The drain valve 12 is composed of a valve seat 12a mounted on the opening 10 provided at the bottom of the tank 11 and a semi-spherical valve body 12b that is openably and closably fitted to the valve seat 12a.

Then, by operating an operation lever (not shown) provided at a required position on the side wall of the tank 11, the valve body 12b is moved to the valve seat 1
The valve can be opened by pulling it up from 2a, the washing water in the tank 11 flows down into the toilet bowl 13 through the opening 10, and the filth inside the toilet bowl 13 is discharged to a sewer pipe (not shown). The inner surface of the bowl of the toilet bowl 13 can be cleaned.

On the other hand, when almost all the washing water in the tank 11 has been discharged,
The valve body 12b naturally descends and is seated on the valve seat 12a to close the valve.

Further, an overflow pipe 14 is installed in the tank 11, and the overflow pipe 14 has a drain valve 12 at its lower end.
Of the valve seat 12a, and its upper end projects above the upper surface of the wash water W.

Further, the overflow pipe 14 also has a function as an auxiliary water supply passage, as will be described later.

On the other hand, a water supply ball tap 15 is arranged in the upper portion of the tank 11, and the ball tap body 16 has its water supply side connected to a water supply pipe 17 and also has its cleaning water flow out into the tank 11 on the water discharge side thereof. Tank water inlet 18 and overflow pipe
Auxiliary water supply port 20 connected to auxiliary water supply pipe 19 for supplying auxiliary water for sealing water, and a hand-washing water supply port (not shown) connected to hand-washing water supply pipe 21 for supplying washing water to the hand-washing device Is provided.

A main valve 22 is disposed inside the ball tap body 16, and the main valve 22 includes a valve body 24 slidably mounted in an opening 23 formed in a lower portion of the ball tap body 16, It is formed of a valve seat 25 corresponding to a valve seat seating surface formed on the upper end of the valve body 24.

The lower end of the valve body 24 is interlockingly connected to a float 26 that floats on the water surface of the tank 11 and moves up and down as the water level rises and lowers through an appropriate communication mechanism 27.

Therefore, the valve body 24 operates in conjunction with the vertical movement of the float 26,
When the float 26 is above, it sits on the valve seat 25 and closes the valve,
When it is below, it opens the valve away from the valve seat 25.

Explaining the toilet bowl cleaning operation by the toilet bowl cleaning device A having such a structure, as described above, the tank 11
Open the drain valve 12 by operating the operating lever provided on the side wall of
Cleaning water can be supplied into the toilet bowl 13 through the opening 10 to discharge waste and wash the toilet bowl 13.

Further, by the supply operation, the main valve 22 of the ball tap main body 16 is opened due to the lowering of the float 26 accompanying the lowering of the water level in the tank 11, the water supply to the tank 11 is started, and the tank 11 is started.
It is possible to continue supplying water into the tank 11 until the main valve 22 is closed due to the upward movement of the float 26 due to the rise of the water level, and at the same time to supply hand washing water and auxiliary water for sealing water to the toilet bowl 13. .

(C) Problems to be Solved by the Invention However, the toilet bowl cleaning tank device A still has the following problems to be solved.

That is, as shown in FIGS. 4 and 5, the overflow pipe 14 has a vertical pipe portion 14a and a vertical pipe portion 14a for preventing abrupt inflow of the auxiliary water for sealing into the drain valve 12. And a slant pipe portion 14b that connects the lower part of the drainage valve 12 and the internal space of the valve seat 12a of the drain valve 12.

However, as shown in FIG. 5, the lower end of the auxiliary water supply pipe 19 is attached to the upper end of the vertical pipe portion 14a by the fixture 28 with its discharge direction parallel to the axis of the vertical pipe portion 14a. Has been.

Therefore, from the lower end of the auxiliary water supply pipe 19 to the overflow pipe 14
The supplementary water for sealing water that has flowed in flows vertically down along the inner wall B of the vertical pipe portion 14a, and also exerts some impact force discontinuously from the lower end of the inner wall B to the lower surface of the inclined portion 14b. Therefore, when it falls vertically and when it collides with the lower surface of the inclined portion 14b, a large amount of air is taken into the auxiliary water for sealing and flows into the drain valve 12. It will be.

By the way, after opening the drain valve 12 for cleaning the toilet bowl 13, originally, the drain valve 12 is closed due to the decrease of the cleaning water in the tank 11, and the tank 11 is gradually cleaned again. After the water starts to collect and a certain amount of cleaning water is stored, the main valve 22 of the water supply ball tap 15 is closed, and the supply of cleaning water, hand washing water, and auxiliary water for sealing water is stopped.

However, in the above-mentioned sealing water containing a large amount of air and in a turbulent state, the air usually escapes to the toilet side, so that buoyancy to the extent that the drain valve 12 is moved does not occur.

However, for some reason, for example, when the siphon portion of the toilet bowl 13 is blocked due to paper jam, the mixed air cannot escape to the toilet bowl side, and therefore the drain valve
A considerable buoyancy will be generated in the vicinity of 12, and the valve body 12b of the drain valve 12 will cause a so-called chattering phenomenon and will not sit on the valve seat 12a.

Therefore, the drain valve 12 remains half open,
12 and the opening 10 of the tank 11, the wash water and the supplementary water for sealing water continue to flow into the toilet bowl 13 and flow down over the upper edge of the bowl portion of the toilet bowl 13 onto the floor of the toilet. , Not only would it cause an extremely unsanitary condition, but there is also a risk that the room will be wet.

An object of the present invention is to provide an auxiliary water supply structure in a toilet bowl cleaning tank device that can solve the above problems.

(D) Means for Solving the Problems The present invention is to provide a water supply ball tap in a tank that communicates with a toilet via a drain valve, and an overflow pipe that communicates with the toilet in the same tank. And the lower end of the overflow pipe is connected to a drain valve, and a tank water supply port and an auxiliary water supply port are provided in the outflow side flow path of the water supply ball tap, and the auxiliary water supply port is connected to the auxiliary water supply port. The present invention relates to an auxiliary water supply structure in a toilet bowl cleaning tank device connected to the lower portion of an overflow pipe or the vicinity of a drain valve via a supply pipe.

(E) Operation and Effect With the above-described configuration, the present invention has the following operation and effect.

In the present invention, the auxiliary water supply port is connected to the lower portion of the overflow pipe or the drain valve via the auxiliary water supply pipe.

Therefore, the auxiliary water for sealing water can flow into the toilet bowl almost directly through the drain valve without vertically falling in the vertical pipe portion of the overflow pipe.

Therefore, it is possible to almost eliminate the phenomenon in which the auxiliary water for sealing becomes a turbulent state and mixes air during the flow in the overflow pipe, so that the kinetic energy of the auxiliary water for sealing and the buoyancy of the mixed air are effectively reduced. After cleaning the toilet bowl by opening the drain valve, the valve body of the drain valve can be firmly seated on the valve seat, and the ball tap can be operated reliably for cleaning water, hand washing water and sealing water. Since it is possible to reliably stop the supply of auxiliary water, it is possible to reliably prevent continuous outflow of dirty water from the toilet bowl even if the toilet bowl becomes blocked.

(F) Embodiment Hereinafter, the present invention will be specifically described based on an embodiment shown in the accompanying drawings.

1 to 3 show a specific structure of an auxiliary water supply structure which is a main part of a toilet bowl cleaning tank device B according to the present invention.

As shown in the figure, this auxiliary water supply structure has the same structure as the auxiliary water supply structure described in the section of the prior art, and in this embodiment, the same structure is indicated by the same reference numeral.

However, in the present embodiment, as shown in FIG. 1, the auxiliary water supply pipe 19 is provided inside the drain valve 12 without causing turbulent flow of the auxiliary water for sealing water and without involving air. It differs from the conventional configuration shown in FIGS. 4 and 5 in that it has a configuration in which it is connected to a drain valve 12 so that it can flow into.

That is, as shown in FIG. 1, the inclined pipe portion 14b of the overflow pipe 14 has a connecting plug 30 protruding from the upper wall thereof.

The connecting plug 30 has an extension pipe 32 for supplying auxiliary water, which is connected to the tip of the auxiliary water supply pipe 19 using a connecting cylinder 31.
The lower end of is attached.

In order to fix the extension pipe 32 for supplying auxiliary water to the overflow pipe 14, the extension pipe 32 for supplying auxiliary water is provided in parallel with the vertical pipe portion 14a of the overflow pipe 14 and for connection provided at the upper end thereof. Insert the cylindrical body 31 into the vertical pipe portion 14 of the overflow pipe 14.
It is supported by an annular support portion 33 provided at the upper end of a.

With this structure, the auxiliary water for sealing water supplied from the water supply ball tap 15 to the toilet bowl 13 via the auxiliary water supply pipe 19 is, as shown in FIG. 1, the auxiliary water supply pipe 19 and the auxiliary water supply extension pipe. Through 32, it flows into the middle part of the inclined pipe portion 14b of the overflow pipe 14, and then flows into the drain valve 12.

As described above, in the present embodiment, the auxiliary water for sealing water flows down into the drain valve 14 with almost no flow down within the overflow pipe 14, so that it occurs when it is flowing down within the overflow pipe 14. It is possible to almost completely eliminate the inclusion of air into the auxiliary water for sealing water, and it is possible to significantly reduce the rising energy of the valve body 12b of the drain valve 12 due to the auxiliary water for sealing water containing air.

Therefore, after the flushing operation of the toilet bowl 13 by opening the drainage valve 12, the valve body 12b of the drainage valve 12 can be reliably seated on the valve seat 12a, and the water tap ball tap 15 can be reliably operated.
Since it is possible to reliably stop the supply of wash water, hand wash water, and auxiliary water for sealing water, even if the toilet bowl 13 is blocked,
It is possible to reliably prevent continuous outflow of dirty water from the toilet bowl 13.

Further, FIG. 2 and FIG. 3 show another embodiment. In this embodiment, the auxiliary water supply extension pipe 19 or the auxiliary water supply extension pipe 32 is directly connected to the drain valve 12. It is characterized in that it is connected to a connecting plug 33 provided on the side wall of the seat 12a.

In this case, since it is possible to completely eliminate the flow of the sealing water supplemental water in the overflow pipe 14, it is possible to further prevent air from being mixed into the sealing water supplementary water. The seating operation of the valve body 12b on the valve seat 12a can be made more reliable, and the continuous outflow of wastewater to the outside can be further surely prevented.
