Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a flushing valve for supplying an appropriate amount of water to a simple flush toilet and for opening the discharge hole of the toilet to supply water and flush the toilet.

[Conventional technology]

A simple flush toilet is a type of toilet that is used in areas without sewage facilities and stores feces and flush water discharged from the toilet in a sewage tank. Since the capacity of this sewage tank is limited, in order to reduce the number of times of pumping, it is desirable to use as little washing water as possible to increase the washing effect.

With conventional simple flush toilets, both when defecating and urinating,
After using the toilet, press the foot pedal to drain the washing water.
They were responsible for discharging waste and cleaning the toilet bowl, which required a lot of water when defecating.

To solve these problems, there is a simple flush toilet proposed in Japanese Patent Application Laid-Open No. 115040/1983. This involves attaching a lid that opens and closes using a foot pedal to the filth discharge hole in the toilet bowl, which normally closes the filth discharge hole, and attaching a hand lever to the flush water tank attached to the back of the toilet body. It is equipped with a drain valve that opens when operated. When using the toilet, operate the hand lever to store a certain amount of water in the filth discharge hole, and then press the foot pedal after defecating to open the lid and drain the filth and the stored sewage. At the same time, the flush water tank's drain valve is activated to flush the inside of the toilet bowl with a small amount of water. When running a small errand, the user depresses the foot pedal after relieving himself without operating the hand lever. Thereby, the amount of washing water used can be minimized.

At this time, when the foot pedal is released, the lid closes the waste discharge hole, but since there is a distance between the drain valve of the flush water tank and the waste discharge hole of the toilet body, the flush water does not flow even after the drain valve is closed. This will flow into the waste discharge hole. Therefore, a predetermined amount of cleaning water is always stored in the waste discharge hole, and the space between the waste water tank and the waste discharge hole is sealed with water, thereby preventing the generation of odor.

[Problem that the invention attempts to solve]

However, this conventional simple flush toilet has a structure in which a wash water tank is attached to the back of a Western-style toilet, and a hand lever is also attached directly to the wash water tank. For this reason, when the flush water tank is installed in a high place like a low tank, it becomes inconvenient to attach the hand lever to the low tank, and it cannot be applied to low tank type toilets like Japanese style toilets. It was hot.

The present invention was devised in view of these conventional problems, and provides a cleaning valve that can be installed in pipes from water supplies and low tanks to save water and prevent odor from cleaning. The purpose is to

[Means for solving problems]

In order to achieve this purpose, the cleaning valve of the present invention has the following features:
A valve body that closes an opening formed between a water supply channel and a drainage channel inside the valve body is provided in the middle of a valve shaft that is installed so as to be able to penetrate the valve body and move in the axial direction of the valve body. A spring is provided to keep the valve normally closed, a push button is provided at one end of the valve shaft to open the valve by moving the valve shaft against the elastic force of the spring, and a driving piece is provided at the other end. ,
A handle is provided that engages with the drive piece and can be rotated around the valve shaft, and a pull cable that is connected to an opening/closing mechanism of the sewage discharge valve of the toilet body is connected to the handle, and when the handle is rotated. The present invention is characterized in that a valve shaft moving mechanism for moving the valve shaft in the valve opening direction is provided.

〔Example〕

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

FIG. 1 is a plan view of an embodiment of the present invention, FIG. 2 is a longitudinal sectional side view taken along the - line in FIG. 1, and FIG. 3 is a rear view. 1 in the figure is the valve body, and as shown in detail in Figure 2, there is a division inside between the water supply channel on the right (upstream side) and the drainage channel on the left (downstream side). A partition wall 2 is provided, and a valve hole 3 (see FIG. 4b) is provided in the upper part of the partition wall 2. This valve hole 3 is provided on opposite side walls of the valve hole 3.
openings 4 and 5 concentric with and projecting outward;
are provided on the upstream side and the downstream side of the valve body 1, respectively (see Fig. 4b and Figs. 5 to 7).
Further, as shown in FIGS. 2, 4a, and 4b, through the opening 4 of the valve body 1, a spring receiver 7, a valve seat gasket 8, a valve guide 9, and a rotary cam 10 are installed in order from the upstream side to the downstream side. A valve stem 6 is inserted into which the valve stem 6 is fixed.

As shown in FIGS. 2 and 4b, the upstream opening 4 has a fixed shaft 11 having a notch 13 on one side of the flange 12, and a cap nut with the valve shaft 6 inserted into the shaft hole. 15, it is watertightly attached via an O-ring. A compressed coil spring 16 is inserted into the valve shaft 6 between the spring receiver 7 and the flange 12 of the fixed shaft 11, and its elasticity causes the valve seat gasket 8 to come into contact with the valve hole 3 on the upstream side. The valve hole 3 is normally closed in contact with the valve hole 3.

As shown in FIGS. 8a and 8b, the downstream opening 5 is provided with a fixed cam 1 having a serrated cam surface.
7 is in a state where the valve stem 6 is inserted into the center hole,
The rotary cam 10 shown in FIGS. 9a and 9b is mounted watertight with a cap nut 18 so that the cam surface meshes with the rotating cam 10 shown in FIGS. 9a and 9b.

As shown in FIGS. 10a and 10b, the fixed shaft end 14 protruding from the cap nut 15 has a handle 19 having a pull cable attachment portion 23 at the tip thereof on the side facing the flange 12 of the fixed shaft 11. Two pins 21 are provided protruding around one side, and a fitting hole 20 with a notch 22 around the other side is fitted into the pin 2.
1 is engaged with the notch 13 of the fixed shaft 11, so that it can be rotated by a predetermined angle.

At the end of the valve shaft 6 protruding from the fixed shaft 11, a first
As shown in FIGS. 1a, 11b, and 11c, the cap-shaped drive has two pawls 25 that engage with the notches 22 of the handle 19, and has a large number of parallel grooves 26 on the inner peripheral surface. The top 24 and, as shown in FIGS. 12a and 12b, a gear-shaped water amount adjustment piece 28 having a large number of parallel protrusions 29 on its outer peripheral surface, the former parallel groove 26 and the latter parallel protrusion 29. It is attached to the valve stem 6 with a screw in a state where the two are engaged with each other. The water volume adjustment piece 28 itself is non-rotatably fitted to the end of the valve shaft 6, and the drive piece 24 is positioned relative to the water volume adjustment piece 28 due to the meshing position between the parallel groove 26 and the parallel protrusion 29. It is possible to change the positional relationship. Therefore, water volume adjustment piece 2
When the drive piece 24 is attached to the drive piece 8, by adjusting its angle and changing the engagement between the parallel grooves 26 and the parallel protrusions 29, the claw 25 formed on the drive piece 24 can be attached to the cutout part of the handle 19. By changing the engagement relationship with 22, the rotation angle of the drive piece 24 can be adjusted. That is, by adjusting the angle at which the notch 22 of the handle 19 starts to engage with the pawl 25 formed on the drive piece 24 when the handle 19 is pushed down, the maximum rotation angle of the valve shaft 6 can be adjusted. . In FIGS. 11a and 11b, reference numeral 27 indicates a water amount adjustment scale that serves as a guide for the amount of water when adjusting the drive piece 24.

A push button 30 is attached to the other end of the valve shaft 6 protruding from the fixed cam 17 and the cap nut 18.

The flush valve of the present invention has the above-mentioned structure,
Push button 30 for a simple flush toilet (not shown)
The outflow side of the flush water is attached to the front of the toilet so that it faces. In addition, the pull cable attachment part 23
A pull cable 23a is connected between this and a discharge valve (not shown) provided at the discharge port of the simple flush toilet.

Therefore, when the user presses the push button 30, the valve stem 6 moves in the axial direction, and the valve seat gasket 8, which had closed the valve hole 3, opens the valve hole 3 and opens the discharge port of the toilet bowl. Water is supplied to the toilet bowl without water. As a result, the area near the outlet of the toilet bowl, which is closed by the discharge valve, is filled with water, and no odor from the toilet tank leaks. After using the toilet,
When the user presses down the handle 19, the fixed shaft end 1
The fitting hole 20 rotates around 4, and the pin 21 engaged with the notch 13 provided on the side of the flange 12 of the fixed shaft 11 prevents the fitting hole 20 from rotating within a limited range. limited to. Furthermore, the fitting hole 2 of the handle 19
Two pawls 25 of a drive piece 24 attached to the end of the valve stem 6 are engaged with the notch 22 on the other side of the valve stem 6 to further restrict rotation of the handle 19. This rotation range can be changed by adjusting the engagement angle of the driving piece 24 with the water amount adjusting piece 28 as described above. For this reason,
Rotation of the drive piece 24 attached to the tip of the valve stem 6 is restricted, and the valve stem 6 is rotated by a predetermined angle. Therefore, since the rotary cam 10 rotates while meshing with the fixed cam 17 fixed to the valve body 1, it is moved in the axial direction of the valve shaft 6, and the valve hole 3 is similarly removed from the valve seat packing 8. Open it to allow water to drain into the toilet bowl. At the same time, handle 19
pulls the pull cable 23a attached to the pull cable attachment part 23 at the tip of the handle, opens the drain valve of the toilet bowl, and drains the waste along with water.

[Effect of idea]

As explained above, in the present invention, a valve stem is installed so as to be movable in the axial direction of the valve body, and the valve stem is operated by a push button and a handle. The handle is connected to a pull cable that is linked to the opening/closing mechanism of the sewage discharge valve on the toilet body. Therefore, when defecating, press the push button to supply flushing water without opening the toilet discharge valve, and collect water in the discharge hole of the toilet body to form a water seal with the toilet tank and prevent backflow of odors. can do. After using the toilet, by operating the handle, flushing water is supplied to the toilet bowl and the discharge valve of the toilet bowl is opened, thereby allowing waste to be discharged and the toilet bowl being cleaned.

Therefore, by simply providing this flushing valve at one location in the piping, it is possible to effectively flush the simple flush toilet using a small amount of water and prevent odor.
