Description

Toilet flushing device {device for automatically flushing toilet bowls}

The present invention relates to a toilet flushing device, and more particularly, to a toilet flushing device that can be used to distinguish between urine and feces.

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 5-6 times a day, so multiplying this by the number of family members means that the total amount of water consumed by urine in a family is very high, and the cost of purifying it again depends on the amount of water wasted. Will increase.

In order to solve this problem, the applicant has developed a toilet flushing device as shown in FIGS. 1 and 2 so that the discharge of water in feces or urine can be different.

It is provided with a check valve (1) consisting of a lower flange (2) having a hinge portion (2a) of one side and an extension portion (2b) of one side and a bellows portion (5) connected at the lower circumference at the center of the lower flange (2). do.

The pivoting lever 6 is connected between the upper part of the bellows part 5 of the check valve 1 and the extension part, and the urine string 9 is connected between one end of the pivoting lever 6 and the urine lever 4. The urine string 9 is coupled to the floats (3).

And the stool strap (7) is connected between the upper side of the bellows portion 5 and the stool lever (8).

In the conventional toilet flushing device, by pressing the stool tube (not shown) and pulling the stool strap (7), the bellows portion 5 in a compressed state as shown in FIG. When the stool strap 7 is pulled continuously, as shown in FIG. 2, the check valve 1 is opened, and the closing time of the check valve 1 is delayed due to the buoyancy of the bellows part 5. Therefore, a large amount of water is drained.

On the other hand, when the urine string 9 is pulled, the bellows portion 5 of the check valve 1 is opened in a compressed state so that the buoyancy of the bellows portion 5 does not exist, and thus the check valve 1 is quickly closed. A small amount of water is drained.

Therefore, it is possible to vary the amount of water drained at the time of urine or stool, and eventually save water.

However, in the conventional toilet flushing device, when the stool lever is operated, the remaining amount of dirt remains in the toilet without being discharged. On the other hand, when the urine lever is operated, the waste is not properly discharged and a part of the toilet remains in the toilet. It was.

The reason for this is that when the stool strap 7 is operated, the water in the tank is drained, and the water level is gradually lowered to a level below the proper height. The above-mentioned phenomenon occurs because the drainage speed increases rapidly immediately before the water in the tank is completely discharged, that is, just before the check valve 1 is closed, while the water in the tank is slightly discharged and closed when the urine string 9 is operated. Because it is not.

An object of the present invention for solving the above problems is to provide a flushing device for toilet bowl to reliably discharge the dirt in the toilet bowl while discharging a small amount of water during urine.

The toilet flushing device of the present invention for achieving the above object is a toilet flushing device provided with a check valve for hinged one side to the overflow pipe to open and close the drain port of the bottom of the tank, having a hollow shape, shrinkage and A height adjusting member which is expanded and has a first elastic bracket and a second elastic bracket each of which extends upwardly from both sides of the lower outer circumferential surface; A hollow guide having a lower portion positioned inside the height adjusting member, coupled to an upper outer circumference of the upper inner circumference of the height adjusting member, and having a coupling portion protruding outwardly on an upper circumference of the upper side; An air chamber having a through hole formed at a bottom thereof is provided, and a flange is formed around the air chamber so as to be in close contact with the upper circumference of the guide. A long length rotating lever is formed on one side of the flange, and one side of the rotating lever is coupled to the guide. A check valve hinged to the outer end, the outer end of the pivoting lever being coupled to the first elastic bracket; A known urine string connected to the upper guide portion adjacent to the coupling portion; It is characterized in that it is further provided with a known stool strap connected to the free end side of the check valve.

One feature of the flushing device for the toilet of the present invention, the height adjustment member, the bellows portion having a plurality of corrugations between the upper flange and the lower flange to be contracted and expanded in the vertical direction.

Another feature of the flushing device for the toilet according to the present invention, the first elastic bracket and the second elastic bracket, the first horizontal extension portion and the second horizontal extension portion formed horizontally on both sides of the lower flange of the height adjustment member, and the first horizontal An extension portion and a second vertical extension portion extending upwardly from an outer end of the extension portion and the second horizontal extension portion; A plurality of first coupling holes and second coupling holes are formed on the first vertical extension portion and the second vertical extension portion at equal intervals, respectively; A plurality of first uneven parts and second uneven parts are formed below the first vertical extension part and the second vertical extension part so as to elastically bend the first vertical extension part and the second vertical extension part when the height adjusting member is compressed.

Therefore, when the urine string is pulled, the check valve is opened after the height adjusting member is inflated, which is because the height of the drain passage is increased by the inflated height of the height adjusting member, so that water passes through the height adjusting member and the inner circumferential surface of the drain opening. The water pressure that acts is reduced accordingly, and if a small amount of water is discharged and the check valve is closed, a cavity is generated in the center of the drain passage, and the flow rate is increased, so that the water supplied suddenly and quickly becomes dirty from the toilet. Since the remaining amount is pushed out reliably, there is an effect that the inside of the toilet is cleaned without any part of the dirt.

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

First, among the conventional toilet flushing device with a different amount of water discharged during the stool and urine, when the stool strap is pulled, the dirt in the toilet is completely discharged, but when the urine string is pulled, the reason why is not as follows.

When the stool strap is pulled while the tank is full of water, the water passes through the narrow drain hole and resistance is generated around the drain hole.In the initial stage of drainage, the resistance acting around the drain hole is relatively high due to the high water level. Is not that big.

In this state, when the water level is gradually lowered to an appropriate height, the water pressure acting on the inner circumferential surface of the drain port decreases drastically, and a cavity is generated in the center of the water passing through the drain port. Immediately before the valve closes, the drainage speed increases rapidly.

Therefore, the residual amount of dirt in the toilet is pushed out through the trap at the bottom of the toilet by the large amount of water supplied into the toilet at a high speed before the check valve is closed so that the residual amount of dirt does not remain in the toilet.

On the other hand, when the urine string is pulled out, the check valve closes immediately after a small amount of water is discharged while the tank is full, so that the water pressure is relatively high due to the relatively high water level on the inner circumference of the drain from the time the check valve is opened. This acts, so that the water in the water tank is supplied to the toilet side, and the check valve is closed to shut off the water supply.

Therefore, when the urine string is pulled and drained, there is no sudden drop in water pressure and cavitation occurring after the fecal string is pulled out, and thus, it is impossible to reliably push out the remaining amount of dirt in the toilet bowl. Does not pass through the trap at the bottom of the toilet, and flows back into the toilet.

3 and 4 is a partially exploded perspective view and a sectional view showing a combination of the water flushing device of the present invention for solving such a conventional problem, the bottom of the water tank (T) is coupled to the drain hole (H), The upper periphery is coupled to the lower end of the height adjustment member 10, which is a feature of the present invention, the nut (N) is fastened to the lower periphery of the drain hole (H) firmly coupled to the height adjustment member (10) and the drain (H) Doing.

First, the flushing device for the toilet of the present invention is divided into the height adjusting member 10, the guide 30, the check valve 40.

The height adjusting member 10 has a hollow shape, and is contracted and expanded in the vertical direction, and a bellows portion 11 having a plurality of wrinkles is suitable as such a structure.

The upper flange 12 is provided around the upper end of the bellows portion 11, the lower flange 13 is provided around the lower end, and the first elastic bracket 14 and the second elasticity are provided at both sides of the lower flange 13. Brackets 19 are formed, respectively.

The first elastic bracket 14 has a N-shaped bar shape as a whole, a first horizontal extension part 15 extending horizontally on one side of the lower flange 13 of the height adjusting member 10, and a first horizontal extension. The part 15 consists of a first vertical extension part 16 extending upward from the outer end.

A plurality of first coupling holes 18 are formed in the upper part of the first vertical extension part 16 at equal intervals, and a plurality of first uneven parts 17 are formed in the lower part to compress the height adjusting member 10. The vertical extension part 16 is elastically bent flexibly.

The second elastic bracket 19 has the same shape as the first elastic bracket 14, the second horizontal extension portion 20 extending horizontally to the other side of the lower flange 13 of the height adjusting member 10, The second horizontal extension part 20 consists of a second vertical extension part 21 extending upward from the outer end.

A plurality of second coupling holes 23 are formed at equal intervals on the upper part of the second vertical extension part 21, and the second vertical extension part 21 is flexibly elastically bent when the height adjusting member 10 is compressed. A plurality of second uneven parts 22 are formed below the vertical extension part 21.

3 to 7 show the same length of the first elastic bracket 14 and the second elastic bracket 19, the second elastic bracket 19 is formed longer than the first elastic bracket 14 Any one may be used as long as the first elastic bracket 14 is completely unfolded before the second elastic bracket 19 is fully unfolded.

On the other hand, the guide is provided with a hollow cylindrical portion 31, when the bellows portion 11 is unfolded, an air chamber 10a is provided between the bellows portion 11 and the cylindrical portion 31, the cylindrical portion 31 The upper plate 32 is provided around the upper end, and the sealing protrusion 33 is formed on the upper plate 32 such that the flange 43 of the check valve 40 to be described later is in close contact with the upper plate 32.

A support protrusion 34 is formed around the cylindrical portion under the upper plate 32 so that the upper flange 12 of the height adjusting member 10 is fitted into the groove between the support protrusion 34 and the upper plate 32. (32) A pair of engaging portions 35 are formed on one outer circumferential surface.

The urine string 36 is connected to the upper plate 32 of the guide 30 adjacent to the coupling part 35, and the extension protrusion 37 is extended in the horizontal direction on the outer circumference of the upper plate 32 opposite to the coupling part 35. It protrudes so that it may be selectively engaged with the second engagement hole 23 of the second elastic bracket 19.

The check valve 40 has an air chamber 41 having an air chamber therein and is divided up and down, and the flange 43 so as to be in close contact with the sealing protrusion 33 of the guide 30 around the air chamber 41. Is formed, the long length rotating lever 44 is formed on one side of the flange 43.

Here, the pivoting lever 44 has an outer end thereof selectively supported by the first engagement hole 18 of the first elastic bracket 14, and the pivoting lever 44 is firmly attached to the first engagement hole 18. Coupling grooves 46 are formed at the outer ends of the rotation levers 44 so as to be coupled and supported.

In addition, hinge pins 45 protrude from both sides of the rotation lever 44 adjacent to the flange 43, and the hinge pins 45 are hinged to the coupling part 35 of the guide 30.

And the stool strap 47 is connected to the opposite side of the flange 43 to which the rotation lever 44 is connected, that is, the free end of the check valve 40.

In this regard, the coupling groove 46 of the pivot lever 44 is coupled to the first coupling hole 18 on the uppermost side of the plurality of first coupling holes 18 formed in the first elastic bracket 14, The extension protrusion 37 of the 30 is coupled to the lowermost second coupling hole 23 of the plurality of second coupling holes 23 formed in the second elastic bracket 19.

The flushing device for a toilet according to the present invention has a configuration such that the check valve 40 is opened in the compressed state of the height adjusting member 10 by pulling the stool strap 47 in the state as shown in FIG. 4, and the open check valve 40 is opened. The buoyancy of the air chamber 41 is not closed until most of the water in the tank is discharged.

As such a large amount of water is discharged, the water level in the water tank (T) is gradually reduced to approach the bottom of the water tank (T), and thus the water pressure is significantly reduced, so that the resistance acting on the inner circumferential surface of the drain hole (H) is significantly reduced. As the phenomenon occurs in the center of the drained water, the remaining water in the tank is quickly discharged immediately before the check valve 40 is closed.

Therefore, some dirt remaining in the toilet is discharged through the trap (not shown) to the discharge pipe (not shown) by the pressure of the water discharged quickly from the drain (H) of the water tank (T), so that the remaining amount of dirt does not remain in the toilet. do.

On the other hand, when pulling the urine string 36 in the state as shown in FIG. 4, the bellows portion 11 of the height adjusting member 10 gradually expands upwards, and when expanded above an appropriate height, the height adjusting member 10 of FIG. The first elastic bracket 14 is fully extended.

Therefore, the end of the rotation lever 44 is supported by the first elastic bracket 14 fully extended, so that the urine string 36 cannot be moved upward even if it is pulled further.

If the urine string 36 continues to be pulled in such a state, the bellows portion 11 and the guide 30 are lifted up, and thus the guide 30 is lifted while the end of the pivot lever 44 is supported. Since the hinge pin 45 is lifted upward, the check valve 40 is opened as shown in FIG. 7.

Thus, when the check valve 40 is opened while the urine string 36 is pulled out and the height adjusting member 10 is fully inflated, the water corresponding to the height of the expanded height adjusting member 10 can be saved. Will be.

In addition, since pulling the urine string 36, the height adjusting member 10 is expanded, so that the position of the drain opening is increased by the inflated height.

The flushing device for the toilet of the present invention has the effect that the water level is reduced by the inflated height of the height adjusting member 10, and thus the resistance of the water acting on the inner circumferential surface of the height adjusting member 10 during the discharge of water is relatively reduced, and thus the water Even if only slightly discharged, the water level is close to the upper flange 12 of the height adjusting member 10, so that the water is quickly discharged immediately before the check valve 40 is closed while the phenomenon occurs in the drainage passage.

Therefore, some dirt remaining in the toilet by the discharge pressure of the water quickly discharged from the inside of the height adjustment member 10 and the drain (H) is discharged to the discharge pipe over the trap so that the remaining amount of dirt in the toilet does not remain.

Therefore, the sudden drop in water pressure and cavitation occurring at the time of the last drain after the stool string 47 is pulled out also occurs at the time of the last drain after the urine string 36 is pulled out. It is pushed out reliably, thereby solving the conventional problem that some of the dirt does not pass through the trap and flows back into the toilet.

Such a toilet flushing device of the present invention can not only save water in the water tank T by the height of the height adjusting member 10 when the urine lever is operated, but also cleanly discharge some of the dirt without leaving the toilet. .

Here, as the coupling groove 46 of the rotation lever 44 is coupled to the upper first coupling hole 18 of the plurality of first coupling holes 18, and the extension protrusions 37 of the guide 30 are increased. As the second coupling holes 23 of the second coupling holes 23 are coupled to the lower second coupling holes 23, the distance difference between the first elastic brackets 14 and the second elastic brackets 19 is gradually narrowed. Accordingly, the open angle of the check valve 40 also gradually decreases.

Therefore, it is possible to adjust the opening angle of the check valve 40 by adjusting the coupling position thereof.

According to the flushing device for toilet according to the present invention as described above, when the urine string 36 is pulled, the check valve 40 is opened after the height adjusting member 10 is expanded, which is the end of the height adjusting member 10 Since the height of the drain passage is increased by the expanded height, the water pressure acting on the inner circumferential surface of the height adjusting member 10 and the drain hole H through which the water passes is reduced by that amount, so that a small amount of water is discharged and a check valve If the 40 is to be closed, the flow rate is increased by generating a cavity in the center of the drainage passage, so that the water supplied suddenly and quickly pushes the remaining amount of the dirt in the toilet bowl cleanly without leaving any part of the dirt inside the toilet bowl. It has the effect of being washed.
