Description

[Detailed description of the invention] This invention suppresses the drastic spouting of flushing water in flush toilets, especially Western-style toilets, ensures smooth flushing inside the toilet bowl, uneven flushing, and further improves the discharge of flushing water. This invention relates to the disclosure of a buffer washing structure that always keeps the amount of water flowing within a certain range.

Previously, this type of Western-style toilet was flushed by connecting directly to the water pipe or by installing a low tank to draw the flushing water into the toilet. Even in this case, the jetting pressure is increased to provide a sufficient amount of water to flush the inside of the toilet bowl.

However, in such a washing method, the amount of clean water consumed is large and it also produces a peculiar washing sound when used, so recently, in order to avoid these inconveniences, washing water Swirling jets have been attempted. However, in order to effectively clean the inside of the toilet bowl during swirling jetting of flushing water, the jetting nozzle is positioned at the upper side relatively close to the toilet seat, and the orientation of the nozzle is generally horizontal or close to this. As a result, splashes of washing water often stain the toilet seat surface during flushing, resulting in an inconvenience.

The buffer cleaning structure according to the present invention has been specially devised in view of the inconveniences in the prior art, and aims to regulate the discharge pressure of the jetted cleaning water and quantify the discharge amount. The gist of its configuration is that an operating hole portion is provided between a flushing water discharge nozzle that opens toward the inside of the flush toilet and a valve that opens and closes a water supply pipe that communicates with this discharge nozzle. A buffer valve plate supported by a spring is slidably fitted into the operation hole, and abuts on the opening surface of the hole or split formed in the valve plate;
A stopper plate for blocking this is placed at a point on the side in front of the movement of the valve plate, which is moved with discharge washing water pressure against the spring. Considerable design changes are planned.

Hereinafter, one embodiment of a typical buffer washing structure according to the present invention will be described with reference to the attached drawings. 1 is a Western-style toilet bowl body, 2 is a ball placed on the toilet bowl body 1, and the toilet seat Discharge port 3 on the lower side of the collar 2a
It is designed so that it can be opened. Reference numeral 4 indicates a toilet seat, 5 indicates a frame on which the toilet seat 4 and the like are mounted, and 6 indicates a lever for opening and closing the scoop 7 and the flush valve 8.
Further, numeral 9 denotes a low tank, which supplies flushing water under pressure into the toilet bowl.

The toilet structure described above is an example of implementing the buffer flushing structure according to the present invention. Changes in the configuration, integration of the frame 5 with the main body 1, changes in the valve device, etc. are planned separately.

The device a according to the present invention is interposed between the discharge port 3 and the valve 8 in the thus constructed toilet bowl, and is usually designed to be installed within the frame 5. The device a has an operation hole 11 of the same diameter that ensures smooth sliding movement of the buffer valve plate 10, and this hole 11 is basically constructed of a straight pipe or the like. It is something.
A shaft rod 12 is horizontally suspended in the longitudinal direction of the hole 11, and the valve plate 10 is slidably fitted onto the shaft rod 12, and the plate 10 is provided with a spring 13. When the washing water flows in from the direction of arrow x, the plate 10 is gently pushed and pushed in the direction of the stopper plate 14.

The plate 10 is fitted into the hole 11 in a generally watertight manner, and a hole 10a is opened to ensure that flushing water flows into the toilet bowl, and the stopper plate 14 is It is resiliently supported by a spring 15 and has a shape and size that completely closes the hole 11 in the plate 10.

When the valve 8 is opened, the cleaning water flows into the hole 11 and hits the valve plate 10, and gently pushes the valve plate 10 toward the stopper plate 14 against the force of the spring 13. While moving, the flushing water is supplied from the hole 10a of the plate 10 to the discharge port 3, and the flushing water is discharged into the toilet bowl under reduced pressure from the mouth 3 and swirled.

Next, when the plate 10 that has been gradually pushed comes into contact with the stopper plate 14, the plate 14 completely closes the hole 10a, and the flow of flushing water into the toilet bowl is regulated. When the valve 8 is closed, the fluid pressure applied to the plate 10 is momentarily reduced, and the plate 10 is moved slightly by the elastic force of the spring 13, and the plates 10 and 14 are separated. A gap is created in between, and the cleaning water in the hole 10 is rapidly drawn out in the direction of the discharge port 3, and the plate 10 is returned to a predetermined position.

Although the spring 15 is intended to improve the contact and adhesion between the plates 10 and 14, it is omitted and the spring 15 is used instead of the hole 10a.
It was separately planned to create a break around the periphery of the

Further, it is further planned that the intervening spring 13 is positioned toward the operating base of the plate 10, and the plate 10 is gently pushed in the direction of the plate 14 by stretching against the elastic force of the spring. It was expected that the same effects would be produced in this configuration.

The buffer cleaning structure according to the present invention has the above-mentioned characteristic structure and operation, and is expected to achieve specific effects on the above-mentioned characteristics.

That is, the flushing water discharged into the toilet bowl flows in while being buffered by the plate 10, stops once when the plate 10 reaches the plate 14, and then, when the valve is closed, the excess water flows out. Due to this structure, there is no splashing caused by sudden jetting when the valve is opened, and the inflowing washing water is quantitative, which saves water.
This prevents splashing and eliminates the characteristic toilet shower noise.

In particular, in the device according to the present invention, by adjusting the tension of the spring 13, the size of the hole 10a in the plate 10, or the sliding width of the plate 10, the appropriate amount of flushing water can be applied to each toilet bowl. This makes it possible to regulate the discharge pressure and discharge amount.

This assumes that there are other conditions that differ depending on the installation conditions of the toilet, especially the problem of the installation position of the low tank or high tank, the specific supply pressure of the directly connected water supply, etc., and it is necessary to immediately respond to these conditions. This makes it possible to apply a constant discharge amount and discharge pressure to the cleaning water.
