Description

Flushing system for toilet bowl {flushing system for toilet bowl}

The present invention relates to a toilet flushing device, and more particularly, to a flushing device for a toilet that is smoothly connected to the water heater and the check valve and does not leak.

Most toilets are equipped with flush toilets, and after flushing the toilet, press the flush lever to supply the water stored in the tank to the toilet to discharge the waste in the toilet to the sewer.

By the way, the problem of the conventional flush toilet, when pressing the flush lever is discharged all the large amount of water stored in the tank irrespective of urine and feces, wasted a lot of water when urine does not need to discharge much water.

Normally, a normal man urinates 5-7 times a day, so multiplying this by the number of family members means that the total amount of water consumed by urine in a household is very high, and the cost of purifying it again depends on the amount of wasted water. Will increase relatively.

In order to solve this problem, as shown in Figs. 1 and 2, a flushing device for a toilet provided with a water storage device 2 in the water tank 1 has been developed. When pulled, the check valve 6 opens and is drained, and as the water level in the water tank 1 gradually decreases, the water reducer 2 is lowered along the guide tube 5, so the top of the open check valve 6 is closed by pressing the check. The valve 6 closes more quickly, thus saving water.

However, such a conventional toilet flushing device has some problems. First, when the water reducer 2 descends and contacts the float part 8 of the check valve 6, a check valve is disposed on one side of the upper part of the float part 8 of rubber material. 6, the front of the lower end is caught so that the force balance between the check valve 6, the guide pipe 5, and the check valve 6 is temporarily stopped so that the check valve 6 does not close even when the water level in the water tank 1 decreases. If the water level is lowered by a certain amount or more, the check valve 6 is bounced and lowered as shown in the imaginary line of FIG. 1 by the weight of the water reducer 2, so that the closing operation is not made smoothly but intermittently. Occurred.

Second, since the connecting string 9 is connected to the inside of the flange of the check valve 6, when the water cutting machine 2 is lowered, it is caught by the connecting string 9 and thus the check valve 6 and the water cutting machine 2 Linkage did not work well.

Third, because the water tank 1 and the coupling pipe 4 are not always coupled under the same conditions, the angle d between the guide tube 5 and the water tank 1 side in each washing device of each home or public building is different from each other. On the other hand, the vertical plane 2d of the water cutting machine 2 should be parallel to the corresponding side of the water tank 1, so that the center of gravity of the water cutting machine 2, not the center of gravity 2c of the water cutting machine 2, as shown in FIG. When one side is pressed to one side of the check valve (6) occurs, in this case, the check valve (6) is pressed in the eccentric state of one side, so the wear and tear is severe, the water cutting machine (2) in the eccentric state The descent operation was not smooth because it descended.

Fourth, if one carefully watches the flushing device of each household, it can be found that even if the check valve 6 is completely closed on the coupling pipe 4, there is often a slight leak, and the check valve 6 As the packing of the wear became more and more worn, it was severe.

An object of the present invention for solving the above-mentioned problems is to provide a flushing device for toilet seats in which the interlocking operation of the water saver and the check valve is smooth and no leakage occurs.

The toilet flush device for the present invention for achieving the above object, the coupling pipe is coupled to the bottom of the tank and having a drain, the guide pipe is formed integrally with one side of the coupling pipe and coupled to the water-saving machine, and coupled to the lower guide pipe In the flushing device for the toilet consisting of a check valve for opening and closing the drainage of the coupling pipe, and one end is connected to the check valve and the other end is connected to the flush lever, the connecting strap for opening and closing the check valve when pressing the flush lever, Float part for opening and closing, and extension part which is formed integrally with both sides of the rear part of the float part and hinged to the lower side of the guide tube, and the semicircular push blades are convex upward on both sides of the upper part of the float part so as to contact the bottom of the water cutting machine. Characterized in that the check valve is further formed.

According to another aspect of the present invention, a float of a check valve includes a hemispherical convex portion having an air chamber therein, a flange extending integrally therewith around a convex portion, and a cylindrical shape protruding downward in the center of the bottom of the flange. The male threaded part, the fitting groove formed around the upper end of the male threaded part, is inserted into the upper side of the outer circumferential surface of the male threaded part so that the male thread is formed on the bottom of the flange, and the packing in which the ring-shaped fitting protrusion protrudes around the inner circumferential surface to be in close contact with the fitting groove; It has a hemispherical shape and an internal thread is formed on the inner circumferential surface so as to be fastened to the external thread, and has a lower cap having a drainage hole at the bottom.

Another feature of the flushing device for the toilet according to the present invention, a connecting groove is formed on the flange outer end of the check valve, the end of the connecting string is coupled to the connecting groove.

Another feature of the flushing device for the toilet of the present invention, the removable groove is formed on both sides of the extension portion of the check valve and the elastic groove is formed on one side of the removable groove is provided with an elastic piece between the removable groove and the elastic groove, the guide to the removable groove Coupling protrusions are formed on both sides of the lower end of the pipe, and the elastic pieces are detached and elastically detached when the detachable grooves are attached to and detached from the coupling protrusions.

Therefore, when the water level is gradually lowered and one part of the bottom of the water reducer is pressed against the pressing blade of the check valve, the upper surface of the pressing blade slides on the bottom of the water cutting machine according to its curvature so that the check valve is closed slowly. The cross operation of the valve is made continuously, and when the check valve closes the drainage port of the coupling pipe, the packing is double sealed by the water pressure in the water tank and the water pressure in the water chamber, so the leak is reliably shut off, and the lower cap of the check valve is screwed. Since it is combined, it is possible to reduce the repair cost of consumables by removing the lower cap and replacing only the packing after replacing the entire check valve when the packing is damaged.

Specific features and advantages of the present invention will become more apparent from the following description with reference to the accompanying drawings.

3 and 4, in the flushing device for the toilet according to the present invention, the coupling pipe 11 having a drain hole 12 is coupled to the bottom of the water tank 1, the coupling pipe 11, one side of the guide pipe 13 It is provided vertically, the lower end of the guide tube 13 is integrally formed around one side of the coupling pipe (11).

In the lower part of the guide tube 13, a pair of engaging projections 14 are formed to protrude outward in accordance with the characteristics of the present invention.

The guide tube 13 is coupled to a known water-saving machine 2 to be elevated in accordance with the water level in the water tank 1, which is a lower closure (2b) in which water is stored and the upper side of the air is filled It consists of the float 2a.

On the other hand, the coupling protrusion 14 of the guide tube 13 is hingedly coupled to the check valve 16, which is the main part of the present invention, the check valve 16 is a float for opening and closing the drain port 12 of the coupling pipe (11). The unit 17 and the extension portion 30 formed integrally with the float portion 17 and hinged to the engaging projection 14 of the guide tube 13.

First, the float portion 17 is provided with a hemispherical convex portion 19 having an air chamber 20 therein as shown in FIGS. 4 to 7, and a disc flange integrally therewith around the convex portion 19. 18 is formed, and the cylindrical male screw part 22 which protrudes downward is formed in the center of the bottom face of the flange 18. As shown in FIG.

In addition, a ring-shaped fitting groove 21 is formed around the upper end of the male screw portion 22, and the outer periphery of the flange is bent downward so that the male thread 24 is formed between the upper surface of the packing 25 and the bottom of the flange 18 to be described later. .

In addition, the packing 25 is coupled to the bottom of the flange, which is fitted on the outer circumferential surface of the male screw part 22, and a ring-shaped fitting protrusion 26 protrudes around the inner circumferential surface to closely contact the fitting groove 21.

On the other hand, the lower cap 27 which is fastened to the male screw part 22 has a hemispherical shape that is open upwards, and a female screw part 28 is formed to be fastened to the male screw part 22 on the upper end of the inner circumferential surface, and a drain hole 29 is formed on the bottom surface thereof. ) Is formed.

And the center of the outer circumference of the flange 18 is formed with a connecting groove 23 in accordance with one feature of the present invention, the end of the connecting string is coupled to the support.

Here, the pressing blades 17a, which are the core elements of the present invention, are formed on the upper surface of the flange 18 on both sides of the convex portion 19. The pressing blade 17a is formed in a semicircular plate shape which is convex upward and is slightly higher than the convex portion 19.

An extension part 30 is integrally formed behind the float part 17 of the check valve, and the extension part 30 has a c-shape as shown in FIGS. It extends from both ends of 17a), on both sides of the extension portion 30 is a detachable groove 31, an elastic groove 34 and an elastic piece 35 therebetween, which is another feature of the present invention.

Detachable groove 31 is a bottleneck 33 formed in a width smaller than the cross-sectional diameter of the coupling protrusion 14 of the guide tube 13, and slightly larger than the cross-sectional diameter of the coupling protrusion 14 on the bottleneck 33 upper side. It consists of a seating portion 32 formed in diameter.

In the present invention, the flushing device for a toilet of the present invention, when pressing the flush lever 10 is pulled by the connecting strap 38, the check valve 16 is opened and the water in the water tank 1 drain 12 of the coupling pipe (11) It is fed to the toilet through.

At this time, the water reducer 2 descends gradually with the water level lowered as it floats on the water and is drained. As shown in FIG. 8, the upper surface of the check valve 16 is opened, namely, as shown in FIG. 8. The upper surface of the blade 17a is in contact.

In this state, the water lowering machine 2 that descends with the water level continuously lowering continues to press the push blade 17a, and the upper surface of the push blade 17a in contact with the bottom of the water cutting machine 2 has the curvature as shown in FIG. Accordingly, the slide valve is pressed downward while sliding from the bottom of the water separator 2, and as shown in FIG. 10, the check valve 16 descended by the water collector 2 before the water is completely drained is drained from the coupling pipe 11. Will be closed.

Since the pair of push blades 17a are formed on the float portion 17 of the check valve 16, the toilet device for flushing the toilet of the present invention has a bottom surface of the float 2a when the water dispenser 2 presses the check valve 16. Since the upper part of the push blade 17a is continuously pressed while sliding along a gentle curvature, the closing operation of the check valve 16 is smoothed.

Therefore, one side of the bottom surface of the lowered water cutting machine is supported by one side of the float portion 17 of the rubber material having high frictional resistance, so that the check valve 16 cannot be pressed smoothly, compared with the water saving machine 2 and the check valve 16. Operation is so smooth that the water saving is always constant.

In the present invention, the flushing device for the toilet according to the position of the guide tube 13, as shown in Figure 11, the center of gravity (2c) of the float (2a) is not located on the two push blades (17a) of the float (2a) Even if one side of the pin is slightly caught by the pressing blade 17a of the check valve 16, there is no relation to the operation.

That is, the two push blades 17a having a gentle curvature are pressed at the same time, only one, or only one portion of the two pressing blades, the contact portion of the pressing force, that is, the bottom of the cutting machine 2 and the pressing blades The upper surface of (17a) is pressed while sliding smoothly by smooth curvature.

Therefore, even when only a part of the water reducer 2 presses the push blade 17a due to the structure of the water washing device, the water cut machine 2 smoothly descends according to the curvature of the gentle push blade 17a, and the check valve 16 is lowered. It is closed continuously according to 2).

Meanwhile, the check valve 16 of the present invention has a connecting groove 23 formed at the outer center end of the flange 18, and the end of the connecting string 38 is coupled thereto, so that the connecting string is pulled to check valve 16. When the check valve 16 is pressed while opening or closing the water reducer 2, a part of the connecting string 38 is not caught on one side of the water dispenser 2.

Therefore, the conventional problem that the connection string interferes with the operation of the water heater is solved.

In addition, the leak check valve 16 of the present invention is completely blocked by the unique configuration of the float portion 17. When the check valve 16 closes the drain port 12 of the coupling pipe 11, the water tank 1 The upper portion of the flange 18 of the check valve 16 is pressed by the hydraulic pressure of the stored water, so that the check valve 16 is primarily sealed.

On the other hand, since the check valve 16 is always submerged in the water of the water tank 1, water is always filled in the water chamber 24 through a gap around the packing 25.

Therefore, the packing 25 of the check valve 16 is firmly adhered to the upper circumference of the coupling pipe 11 by the water pressure in the water chamber 24 and the water pressure in the water tank 1, and the water pressure in the water chamber 24 is upward. It is further increased by the water pressure in the water tank 1 pressed downward and the elasticity of the packing 25 to be elastically restored from the lower side to the upper side, which eventually has the effect of reliably blocking the leak.

Here, the packing 25 is primarily in close contact with the water pressure in the water tank 1 and is intimately in close contact with the water pressure in the water chamber 24.

Conventionally, the entire check valve had to be replaced when abrasion occurred in the packing part. However, the present invention can simply replace the packing 25 when the lower cap 27 is rotated to separate the packing 25. As a result, parts replacement costs can be reduced.

In addition, since the drain hole 29 is formed at the bottom of the lower cap 27, water is not stored in the air chamber 20 of the float part 17.

In order for the check valve 16 to fully function, the air chamber 20 should not be filled with water. In the related art, water was gradually introduced into the air chamber because the outside and the air chamber were not reliably blocked. In this case, even though the water in the tank was not sufficiently drained to the toilet, the check valve was quickly closed.

Therefore, the present invention, even if water is introduced into the lower cap 27, when the check valve 16 is closed in the coupling pipe 11, the water inside the introduced air chamber 20 is the drain hole 29 of the lower cap 27 Since the water flows out into the drain 12 through the air chamber 20, the introduced water is not stored, so the conventional problem is solved.

Another of the advantages of the flushing device for the toilet of the present invention is a coupling structure of the check valve 16. That is, in order to hinge-couple the check valve 16 to the guide tube 13, the fitting groove 14 is opposed to the detachable groove 31, and then is pressed.

At this time, the elastic piece 35 is bent toward the elastic groove 34 by the coupling protrusion 14 and the bottleneck 33 is opened so that the coupling protrusion 14 is seated on the seating portion 32 of the detachable groove 31. When the insertion is completed, the elastic piece 35 is restored and the bottleneck 33 is narrowed to support the coupling protrusion 14 not to fall out.

As such, when the detachable groove 31 of the check valve 16 is opposed to the engaging projection 14 of the guide tube 13 and pressed or pulled, the elastic piece 35 is elastically deformed and restored and the check valve 16 is removed. Is hinged to or separated from the guide tube 13, so that their assembly and separation can be very convenient.

According to the flushing device for toilet according to the present invention as described above, when the water level is gradually lowered and pressed while one part of the bottom surface of the water reducer 2 is in contact with the pressing blade (17a) of the check valve 16, the pressing blade (17a) The check valve 16 is gradually closed as the upper surface of the slide slides at the bottom of the water reducer 2 according to its curvature, so that the cross operation of the check valve 16 by the water dispenser 2 is continuously performed. When 16 closes the drain hole 12 of the coupling pipe 11, the packing 25 is double sealed by the water pressure in the water tank 1 and the water pressure in the water chamber 24, so that the water leakage is reliably shut off. Since the lower cap 27 of 16) is screwed in, if the packing 25 is damaged, instead of replacing the entire check valve 16, the lower cap 27 may be removed, and then only the packing 25 may be removed and replaced. This can reduce the cost of repairing consumables.
