Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a toilet bowl cleaning tank device that can change the amount of flush water supplied to the toilet bowl during a large flush operation and a small flush operation.

Conventional technology> Conventionally, this type of toilet cleaning tank device was developed in the 1970s.
There is one shown in Figure 1 of Publication No. 37707.

To explain this, when performing deep cleaning, when the lever handle 33' is manually rotated toward the large cleaning side, the drain valve body 30', which is a float valve body, is completely pulled up and removed from the drain valve seat 9', and is fully opened. However, even if you remove your hand, the drain valve body 3
The fully open state is maintained due to the buoyancy of 0', and the toilet bowl is flushed even with a substantially constant amount of water stored in the tank body A'. However, when performing a small flush, when the lever handle 33' is rotated by hand to the small flush side, the drain valve body 30' is pulled up slightly from the drain valve seat 9' and separated, opening halfway and flushing water is discharged into the toilet bowl. It starts, but when you take your hand off, the drain valve body 3
0' is attracted by the water flowing out from the drain valve seat 9' and sits on the drain valve seat 9', and the discharge of washing water is stopped.

Therefore, in order to maintain the discharge of washing water, it is necessary to hold the lever handle 33' for a suitable period of time while rotating it toward the small washing side, which is difficult to operate and requires holding. The amount of flushing water varies depending on the time the toilet is in use, which may result in insufficient flushing of the toilet bowl or wasteful flushing of water.

<Problems to be Solved by the Invention> The problems to be solved by the present invention are that not only large flushing but also small flushing can be performed easily, and a constant amount of water is sent to the toilet bowl during small flushing. The aim is to be able to supply

Means for Solving the Problems> The technical measures taken by the present invention to solve the above problems include a tank body, a drain valve seat provided at the bottom of the tank body, and a drain valve seat that opens and closes separately from the tank body. A drain valve that is equipped with a valve body and discharges flush water to the toilet bowl by pulling up the drain valve body, a cylindrical body that is provided surrounding the drain valve and is equipped with an upper inlet and a lower inlet, and the lower part. An on-off valve is provided with an on-off valve body that opens and closes at a distance from the inlet, and is opened and closed by pulling up the on-off valve body, and an on-off valve that is disposed inside the cylinder body and linked to the drain valve body to open the drain valve by buoyancy. A float body that maintains the state, and an operation handle unit that is connected to the drain valve body and the opening/closing valve body through connecting members, respectively, and selectively operates to raise only the drain valve body or to raise the drain valve body and the opening/closing valve body. It is equipped with the following.

<Function> The present invention opens both the drain valve and the on-off valve during a large cleaning operation to allow the stored water to flow to the lower inlet, and during a small washing operation, only the drain valve is opened without interfering with the on-off valve. This allows the stored water to flow up to the upper inlet of the cylinder.

<Example> Hereinafter, one embodiment of the present invention will be described based on the drawings.

In this embodiment, as shown in FIG.
A water supply device B for supplying washing water into the tank body A is provided at the top, and a drainage device C is provided at the bottom to drain the washing water from the tank body A to a toilet bowl (not shown). An operating handle portion D is provided on the side wall 1 facing the water supply device B.

The water supply device B has a water supply pipe 2 connected to a water supply source (not shown) on the inflow side, a water supply pipe 3 extending to near the bottom of the tank on the outflow side, and a handwash pipe 5 provided on the lid 4 of the tank body A. A main valve (not shown) provided between the inflow side and the outflow side is opened and closed in accordance with the vertical movement of the float 7 floating on the water surface. This is a ball tap made like this.

Therefore, when the water supply device B opens the drain valve a of the drainage device C, which will be described later, and drains the water in the tank body A into the toilet bowl, the float 7 lowers as the water level decreases and closes the main valve, and the water supply pipe 2 A part of the water inside is discharged from the water supply cylinder 3 into the tank body A,
The other part is discharged from the hand wash pipe 5 via the communication pipe 6.

On the other hand, in the drain device C, the drain valve a closes when a predetermined amount of water is drained.

Water supply by the water supply device B continues thereafter, and the water in the tank body A begins to rise, and as the float 7 rises accordingly, the main valve is opened and the subsequent water supply is stopped. Next, the drain device C has a drain valve a provided at the bottom of the tank body A, and an on-off valve b provided in a cylindrical body 8 surrounding the drain valve a. The valve seat 9 of the drain valve a is provided on a drain port member 11 made of a synthetic resin such as A-stain resin, which is fixedly attached to the bottom wall 10 of the tank body A by passing through the bottom wall 10 of the tank body A.

That is, the drain port member 11 is formed in a cylindrical shape with an upper half having a large diameter and a lower half having a small diameter, and the lower half penetrates the bottom wall 10 of the tank body A, so that the drain port member 11 has a large diameter in the upper half and a small diameter in the lower half. The drain valve seat 9 is formed on the closed edge of the upper surface of the stepped portion 12 located therein.

In addition, the drain port member 11 has its lower half and the bottom wall 10 of the tank body.
A packing 13 is interposed between the drain port member 1 and the drain port member 1.
This seal 13 and the lower surface of the stepped portion 12 hold the cylindrical body 8 upright. The cylindrical body 8 is made of synthetic resin such as polypropylene, and is a box body with an upper inlet 14 closed on the top surface, and a cylindrical body 8 having approximately the same diameter as the lower half of the drain port 11 is provided at the bottom slope. A hole 15 is opened, and the peripheral edge thereof is held by the stepped portion 12 of the drain port member 11 inserted through the hole 15 and the seal 13.

The cylindrical body 8 also has a lower inlet 16 in the middle of the side plate and a synthetic resin on-off valve body 17 that opens and closes this from the outside to form an on-off valve b, and the lower end of the on-off valve body 17 is rotatably supported by a pair of engagement recesses 18 provided on the outer surface of the side plate so as to rotate in a hinged manner.

The on-off valve body 17 is usually positioned below the lower inflow row 8 due to its own weight and is connected to the on-off valve b, and connects a connecting member 19b such as a ball chain provided at the inner end of the on-off valve body 17 to the lower inflow row 8. By pulling upward through the inlet 18, the on-off valve b can be closed.

The connecting member 19b is operated by an operating handle portion D, which will be described later. Note that the opening/closing valve body 17 is replaced by a 14th valve body instead of a hinge type.
As shown in the figure, the lower inflow row 6 may be formed into a flat plate shape and opened and closed in a sliding manner.

In this example, the on-off valve body 17 is secured to a guide frame provided on the outer surface of the side plate of the cylindrical body 8 so as to be slidable up and down. Further, a water storage cylinder 21 is provided at the upper end of the drain port member 11, and the water storage cylinder 21 is a cylinder made of the same material as the cylinder body 8 and having an inner diameter approximately the same as the upper half of the drain port member 11. The lower end is fixed to the upper green of the drain port member 11 to form a cylindrical body 8.
It stands upright inside the cylinder body 8, and its upper end protrudes upward from the upper end of the cylindrical body 8.

The water tank 21 is a container with a closed bottom, and the drain port member 11 is drained through a small drainage passage 22 in the form of a small hole opened in the bottom.
It communicates with a space 23 formed in the upper half, and the space 23 is formed between the cylindrical body 8, the drain port member 11, and the water storage cylinder 21 via a through hole 24 formed in the side surface thereof. It communicates with the passageway 25.

In addition, a guide hole 26 is provided in the center of the bottom of the water storage cylinder 21, and a guide cylinder 27 is formed upright surrounding this guide hole 26, and the cross-sectional shape is the same as that of the guide cylinder 27 and the outer peripheral wall of the water storage cylinder 21. It has a circular ring shape surrounded on the inside and outside by.

The inner diameter of the water storage cylinder 21 is the same as that of the guide cylinder 27.
An annular hollow float body 28 having a larger diameter and a smaller outer diameter than the outer diameter of the water storage cylinder 21 is accommodated therein, and an operating punch 29 connected to the operating handle portion D is inserted into the guide hole 26 and the guide cylinder 27. It is slidably guided and suitable for insertion.

The operating punch 29 is integrally provided with a drain valve body 30 made of an elastic sheet material such as rubber at its lower end, and a skirt-shaped stopper 31 surrounding the valve body is provided in the middle so as to be inserted into the water storage cylinder 21. The drain valve body 30 is located in the space 23 in the drain port member 11 and corresponds to the drain valve seat 9, and both constitute a drain valve a.

The buoyant force of the float body 28 is the same as the operating village 29 when the drain valve a is open.
Although it is slightly larger than the downward force exerted on the drain valve a
is set so that the water pressure applied to the drain valve body 301 is smaller than the downward force applied to the operating punch 29. The operating punch 29 is a cylindrical body that passes through the top and bottom, and functions as an overflow pipe, and an inverted V-shaped hook 32 is supported on its upper end, and the upper end of the hook 32 is attached to a connecting member such as a chain. It communicates with the operating handle part D via 19a. The operating handle portion D is rotatable within a lever handle 33 provided on the upper part of the outer surface of the side wall 1 of the tank body A, and a bush 37 which is connected to the lever handle 33 at one end and penetrates the side wall 1 at the other end. It consists of an operating shaft 34 that is inserted and extends into the tank body A, and an operating cylinder 35 that is provided at the tip of this operating shaft 34 so that it cannot rotate or move.
A support arm 36b that communicates with the opening/closing valve body 17 via a connecting member 13b is supported at the lower end of the lower surface of 5 so as to rotate only in one direction, and a hook provided at the upper end of the operating punch 29 is supported at the other end. 32 via a connecting member 19a.
a is integrally formed.

Therefore, when the lever handle 33 of the operating handle portion D is turned counterclockwise, for example, in FIG. At the same time, the support arm 36 of the operating cylinder 35
a swings upward and the drain valve body 30 is pulled up via the connecting member 19a and the operating punch 29 to open the drain valve a, but the support arm 36b communicating with the on-off valve body 17 rotates and opens the on-off valve. If the lever handle 33 is turned clockwise without closing the valve b, the protrusion 34a of the operating shaft 34 comes into contact with the notch 37b of the bush 37, and further rotation is restricted and both support arms 36a and 36b both swing upward to open drain valve a, and at the same time, on-off valve body 17 is pulled up via connecting portion village 19b to close on-off valve b. Therefore, such a drainage device C usually has a drainage valve a as shown in FIG.
is closed, on-off valve b is in control, and the reservoir water level is above the upper end of the water reservoir cylinder 21.

Now, when the lever handle 33 for deep cleaning is turned counterclockwise in FIG. As the water pressure disappears, the actuating valve 29 remains raised even with the buoyancy of the float body 28, and even if the lever handle 33 is no longer operated, the valve state of the drain valve a is maintained.
The water in the tank body A is discharged from the upper inlet 14 of the cylinder body 8, the lower inlet row 6, and the upper surface barrier of the water storage cylinder 21 through the passage 25, the through hole 24, and the small drainage passage 22, and is discharged from the drain valve a into the toilet bowl. The water level begins to drop. At this time, the drainage small passage 22
Since the water flow area is extremely small compared to the lower inlet 16 and the through hole 24, when the water level falls from the upper end of the water storage cylinder 21, the rate of decline of the water level in the water storage cylinder 21 is slower than the rate of fall of the water level in other parts. The water level in the water tank 21 is always higher than the water level in other parts.

(Figures 5 and 6) Then, most of the water in the tank body A is discharged into the toilet bowl, and the water level in the tank body A, excluding the water storage cylinder 21, drops to the lower edge of the lower inlet port 16 to reach the required amount of water. Even after flushing, water still remains in the water tank 21, and the float body 28 disposed in the water tank 21 is in a floating state and is pushed through the stopper 31 to the operating pestle 29, that is, the drain valve body 30.
The drain valve a is kept open.

Therefore, after the water level drops to the lower edge of the lower inlet 16, water is supplied from the water supply device B (the water supply from the water supply device B is started as the water level falls due to the operation of the drainage device C) to overcome the lower inlet 16. Only the remaining water continues to be drained,
If the toilet is a siphon type toilet, this water can be used to seal the trap.

In order to increase the amount of water sealing, the lower inlet 1 is located below the cylinder 8.
A small hole may be opened separately from 6.

Thereafter, the water level in the water tank 21 falls as water drains from the small drainage passage 22, and the position of the float body 28 lowers, and accordingly, the drain valve element 30 approaches the drain valve seat 9, closing the drain valve a.

After the drain valve a is opened, the water in the water tank 21 is further drained, and the float body 28 continues to descend and separates from the stopper 31, and the water tank 2
When the water in the tank 1 is completely drained, the float body 28 comes into contact with the bottom of the water tank 21.

On the other hand, as the drain valve a closes, the water level in the tank body A begins to rise (Fig. 7), and water flows from the lower inlet 16 through the passage 25 and through hole 24 between the cylinder 8 and the water storage cylinder 21. Water flows into the water storage cylinder 21 through the space 23 of the drain port member 11 and the small drainage passage 22, and the float body 28 floats to the stopper 3.
I support 1.

(Fig. 8) However, since water pressure is acting on the drain valve body 301, even if the buoyancy of the float body 28 is applied to the working village 29, the working pestle 29 does not rise, and the drain valve a continues to close. . Then, the water level rises further and returns to the state shown in Figure 4. Next, to explain the small cleaning, in this case, when the lever handle 33 is turned clockwise in FIG. is also pulled up and the drain valve a is stopped, and the water in the tank body A flows from the upper inflow row 4 of the cylinder 8 and the upper surface opening of the water storage cylinder 21 to the passage 25, the through hole 24, and the small drainage passage 2.
2, the water is discharged from the drain valve a, and the water level inside the tank body A begins to fall.

At this time, the on-off valve body 17 is attracted by the water flowing in the passage 25 in the direction of closing the lower inlet 16, and the closed state of the on-off valve is maintained even if the lever handle 33 is no longer operated.

The upper end of the cylinder 8 where the water level continues to fall, that is, the upper inlet 14
When the amount of water decreases to a certain level, the amount of water discharged reaches the predetermined amount of water.

(FIG. 9) At this time, water still remains in the water tank 21, and the buoyancy of the float body 28 lifts the drain valve body 30 via the stopper 31, keeping the drain valve a open. On the other hand, the water pressure of the water remaining around the cylindrical body 8 acts on the on-off valve body instead of the suction force caused by the water flowing through the passage 25, and the closed state of the on-off valve b is maintained.

Therefore, the water that has overcome the upper inflow row 4 due to the water supply from the water supply device B and the water in the water tank 21 continue to be drained, and if the toilet is a siphon type toilet, it can be used as a water seal for the trap in the same way as a deep flush. .

At this time, since the water storage cylinder 21 is formed higher than the cylinder body 8, no water flows into the water storage cylinder 21, and the water in the water storage cylinder 21 flows out from the drainage small passage 22 and decreases, and the float body 28
continues to descend, and the drain valve body 30 continues to descend accordingly. (FIG. 10) Then, the water in the drain valve a decreases, and the drain valve body 30 also lowers accordingly, and the drain valve a closes.

After that, the water in the water tank 21 decreases for some time and the float body 28 separates from the stopper 31. (Fig. 11) On the other hand, by opening the drain valve a, the cylinder body 8 gets over the upper end of the cylinder body 8.
The water flowing in fills the space 23 of the drain port member 11, and further water flows into the water storage cylinder 21 from the small drainage passage 22 to float the float body 28 and bring it into contact with the stopper 31.

(FIG. 12) After that, when the water levels inside and outside the cylinder 8 become equal and the pressure inside and outside the cylinder 8 becomes equal, the force pressing the on-off valve body 17 against the lower inlet 16 is released, and the on-off valve body 17
rotates downward under its own weight and reopens the lower inlet 16.

(Fig. 13) At this time, a weight portion 17a is attached to the on-off valve body 17 so that the on-off valve body 17 can smoothly rotate downward.
has been established. The water level in the tank body A continues to rise further and returns to the state shown in FIG. 4. The present invention can be modified in various ways.

For example, there is no need for a water tank. In this case, a general float valve body can also be used as the drain valve body. <Effects of the Invention> Since the present invention has the above configuration, it has the following advantages.

■ During large flushes, both the drain valve and the on-off valve are involved, so the water above the bottom inlet of the cylinder is discharged into the toilet bowl for a large flush, and during small flushes, the on-off valve is closed and the lower inlet is closed. At the same time, the drain valve is opened, so the water above the inlet at the top of the cylinder is discharged into the toilet bowl, and during 4. flushing, the amount of flushing water into the toilet bowl is almost constant not only during large flushes but also during small flushes. Yes, and easy to operate. ■ By changing the height of the upper inlet of the cylinder body, the amount of washing water during 4-washing can be arbitrarily and easily adjusted, and by changing the height of the lower inlet, the amount of washing water during large washing can be adjusted arbitrarily and easily. This allows the optimal amount of flushing water to be delivered to the toilet bowl.

■ Simple structure, easy production, and low cost. ■ Since the small washing operation is easy, the user does not have to perform a large washing after urinating because he/she does not want to perform the 4. washing operation, so water is not wasted.
