Description

A water flapper of toilet bowl's water tank for controlling a water volumn}

The present invention relates to a water displacement-controlled water cover of a toilet bowl, and more specifically, it is possible to selectively adjust the drainage amount of the wash water contained in the reservoir, a toilet that can prevent the leakage of the wash water for a long time and the overflow of the body washing bowl outside It relates to a water discharge adjustable water cover of.

The toilet is composed of a water tank and a toilet main body installed at the bottom of the tank to receive and store the washing water through the ball tap, and the wash water is discharged to the side of the toilet main body when the water cover is opened by the operation of the hand lever installed in the tank. .

Such a conventional discharge structure is to discharge all the washing water stored in the tank irrespective of the type of stool, there was a problem that consumes a large amount of water, especially when urine.

In order to solve this problem as a drainage control device that can be discharged by adjusting the water in two stages, the upper portion of the water cover to open the drain pipe by rotating upward to one side of the drain pipe by the upward pull force to the additional pull force There is a method of providing a separate buoyancy after opening the buoyancy space of the water cover to lose the buoyancy of the water cover or a method of losing the buoyancy by connecting the buoyancy space and the operating lever of the water cover to the exhaust hose.

In Korean Patent No. 263368, "Toilet drainage control device", in order to reduce the buoyancy of the water cover in large and small operating divisions, the inlet of the lower portion of the buoyancy space of the water cover, the exhaust opening, the cover for opening and closing the exhaust port and With the basic configuration of the packing, the opening and closing of the exhaust port according to the pull length of the connecting line is controlled by the force set in the spring. However, in this manner, in the urine operation, since the pull string is pulled by the user's operation, when the exhaust port is closed by the restoring force of the spring after opening for a short time, there is a case where the exhaust capacity is insufficient to operate normally. Therefore, if the exhaust port is made as large as possible, this can be somewhat compensated for. However, foreign matter may be caught between the exhaust port and the packings in contact with the exhaust port, and water in the reservoir may continuously leak due to aging of the packing.

Korean Utility Model Registration No. 164180, "Drainage Control Device for Toilet Seats," is an improvement of the above-mentioned patent. The defect was compensated for. However, this method also does not compensate for the possibility of increased leakage due to the increase of the existing exhaust port. On the contrary, if the iron particles in the water supply are continuously accumulated and accumulated in the magnet, the exhaust port may not be completely closed and a gap may occur, causing a risk of leakage. have. In particular, large buildings such as apartments use very turbid groundwater until immediately before moving in. In this case, a large amount of iron particles are included in the water, which causes the problem that the iron particles adhere to the magnet. Such iron particles are not naturally removed even after the user moves in by using the toilet continuously.

On the other hand, a device that loses buoyancy by connecting the buoyancy space of the water cover and the operating lever with an exhaust hose is installed in the inlet in the lower part of the buoyancy space of the water cover, the exhaust port in the upper part of the buoyancy space, the exhaust hose connected from the exhaust port to the operating lever, and installed in the operating lever. It consists of an exhaust valve. This method has the complexity that both the pull line and the exhaust hose must be connected between the cover and the operating lever (handle lever), and when the water cover is opened and closed, the exhaust hose must also move along, thereby interfering with the reservoir wall and aging the exhaust hose connection part. There is a problem that increases the possibility of leakage.

Accordingly, Korean Patent No. 752589 of the present applicant discloses a toilet lid for adjusting the toilet displacement, which can stably adjust the magnitude of the drainage and prevent leakage of the wash water.

By setting the size of), the water cover does not close quickly in the normal operation, while the buoyancy of the buoyancy space is reduced in the stagnant or reverse flow state to close the water cover. Therefore, the water cover can prevent the leakage of the washing water for a long time and the overflow of the outside of the main body washing bowl even if clogging occurs in the toilet body.

However, in the above-described water volume adjusting water cover of FIGS. 1 and 2, the exhaust port 21 is blocked by the ball 24, so that the inlet gap 51 for gradually reducing the buoyancy in the buoyancy space shown in FIG. 3 cannot be applied. There are disadvantages.

The problem to be solved by the present invention is to stably control the size of the drainage and to prevent the leakage of the wash water, even if the toilet is clogged, even if the drainage of the wash water is not smooth for a long time leakage and overflow of the main body washing bowl It is an object of the present invention to provide a toilet cover for controlling toilet displacement, which can prevent the phenomenon.

Hereinafter, the operating state of the present invention will be described.

First, if you want to wash the stool required a large amount of water, such as feces to rotate the control lever 800 at a small angle pulls the connection line 700 connected thereto.

8 to 11 are views showing a large amount of washing water discharged state according to an embodiment of the present invention.

Referring to FIG. 8, the washing water stored in the reservoir 600 represents a normal water level, and the buoyancy space 250 formed in the space between the cover 100 and the lower cap 200 is an exhaust port 210 and an inlet port 220. Open to the overflow pipe 510 side through the atmospheric pressure state. At this time, the lower opening and closing plate 230 of the lower cap 200 is in a fully open state.

Referring to FIG. 9, when the user operates the hand lever (not shown), the connecting line 700 is pulled, and the cover 100 connected to the connecting line 700 is pulled to rotate the cover to open the reservoir outlet 505. . When the cover 100 is lifted, the washing water stored in the reservoir 600 begins to be discharged to the outlet 505, and the lower opening and closing plate 230 rotates upward by buoyancy and the head pressure of the washing water to block the inlet 220. . At this time, some of the washing water penetrates into the buoyancy space 250 of the cover through the exhaust port 210 and the inlet 220.

Referring to FIG. 10, the cover 100 rotates upward by buoyancy caused by air in the buoyancy space 250, and the body contacting portion 124 of the drive link 120 of the cover contacts the overflow pipe 510. Will stop. When the inlet gap 215 is formed, a small amount of infiltration continues to penetrate into the buoyancy space 250, but the amount is small so that it does not affect the buoyancy of the cover.

Even if the user stops pulling the hand lever 800 and the connecting line 700 is loosened, the cover 100 maintains the water cover open for a predetermined period due to buoyancy caused by air in the buoyancy space 250. While the washing water is discharged to the outlet 505, the water tank is lowered while the water level is lowered along the water surface.

Referring to FIG. 11, when the discharge of the washing water is completed, the water cover closes the outlet 505. At this time, the lower opening and closing plate 230 rotates down by its own weight to open the inlet 220. In addition, outside air enters through the overflow pipe 510 through the exhaust port 210, and some of the infiltration water in the buoyancy space 250 is discharged through the inlet port 220. Subsequently, the washing water is returned to the normal state of FIG. 8 while the washing water is stored in the reservoir through a ball tap supplying the washing water.

12 to 18 are views showing a small amount of washing water discharged state according to an embodiment of the present invention. If you want to wash the stool requiring a small amount of washing water to rotate the lever at a large angle pull the connecting line 700 connected thereto. In order to discharge a small amount of washing water, such as the urine mode, the pulling force of the hand lever (not shown) acts longer than the case of discharging the above-described large amount of washing water, so that the body contact portion of the drive link 120 of the cover 100 ( 124 is in a state that the connection line 700 is still pulled even in contact with the overflow pipe 510 of the body.

Referring to FIG. 12, the wash water stored in the reservoir 600 represents a normal water level, and the buoyancy space 250 formed by the cover 100 and the lower cap 200 overflows through the exhaust port 210 and the inlet port 220. The tube 510 is open to the atmospheric pressure state. At this time, the lower opening and closing plate 230 of the lower cap 200 is in a fully open state.

Referring to FIG. 13, when the user operates the hand lever (not shown), the connecting line 700 is pulled, and the cover 100 connected to the connecting line 700 is pulled to rotate the cover to open the reservoir outlet 505. . When the cover 100 is lifted, the washing water stored in the reservoir 600 begins to be discharged to the outlet 505, and the lower opening and closing plate 230 rotates upward by buoyancy and the head pressure of the washing water to block the inlet 220. . At this time, some of the washing water penetrates into the buoyancy space 250 of the cover through the exhaust port 210 and the inlet 220.

Referring to FIG. 14, the cover 100 rotates upward by buoyancy caused by air in the buoyancy space 250, and the body contacting portion 124 of the drive link 120 of the cover contacts the overflow pipe 510. Will stop. When the inlet gap 215 is formed, a small amount of infiltration continues to penetrate into the buoyancy space 250, but the amount is small so that it does not affect the buoyancy of the cover.

Referring to Figure 15, the body contact portion 124 of the drive link 120 abuts the body overflow pipe 510, the opening of the water cover is stopped at one end. However, since the connecting line 700 is continuously pulled upward, the water cover is lifted up a little while the drive link 120 rotates. As the drive link 120 rotates, the connected vertical link 130 rises. In the embodiment of the present invention, the drive link 120 is rotated to raise the vertical link 130, unlike the connection line 700 directly connected to the top of the vertical link 130 in the state without the drive link 120 To increase the vertical link (130).

As the vertical link 130 rises, the damper cylinder space 139 is compressed while the elastic spring 134 in the guide tube is compressed. At the same time, water and air in the damper cylinder space 139 are discharged to the outside through the micro clearance 133.

In addition, while the guide hypotenuse 155 disposed at the lower end of the vertical link is also raised, the contact arm 235 of the lower opening and closing plate 230 is rotated to the lower side to open the lower opening and closing plate 230 connected thereto, the inlet opening 220 ) Is opened. Therefore, the washing water in the reservoir penetrates the buoyancy space 250 into the gap between the lower opening and closing plate 230 to become the penetration water. As the infiltration water enters the buoyancy space 250, the air existing in the buoyancy space 250 through the exhaust port 210 exits in the form of bubbles (air bubbles). On the other hand, the washing water in the reservoir 600 is discharged through the outlet 505.

Referring to FIG. 16, when the hand lever (not shown) returns to its original position, the vertical link 130 descends and returns to its original position while the driving link 120 is returned by the elastic spring 134.

By the way, the damper cylinder space 139 starts to expand after compression by the elastic spring 134, but the damper cylinder space 139 is delayed in the home position of the vertical link by a predetermined time. That is, the inflow of water into the damper cylinder space 139 is gradually introduced through the micro clearance 133, and the return of the vertical link 130 is delayed by that amount.

Since the return of the vertical link 130 is delayed, the in-situ rotation of the contact arm 235 of the lower opening and closing plate 130 in contact with the guide hypotenuse 155 of the lower end of the vertical link is also delayed, and as a result, the lower opening and closing plate 230 ) And the infiltration water continues to enter the buoyancy space 250 into the gap between the inlet 220. As the infiltration water enters the buoyancy space, air is continuously exhausted to the exhaust port 210. On the other hand, the washing water in the reservoir 600 is discharged through the outlet 505.

Referring to FIG. 17, the micro inflow water is completely introduced into the damper cylinder space 139, and the expansion of the damper cylinder space 139 is completed. In addition, the buoyancy space 250 is filled with the infiltration water and the exhaust of the air is completed, the water cover is not buoyancy is rotated down by the closing force by the flow of the washing water discharged due to its own weight and the closing is started.

Referring to FIG. 18, the cover 100 loses buoyancy to complete the closing while leaving the urine level. In this case, it is closed at a level higher than the closing level in the case of discharging a large amount of water, leaving the remaining washing water in the reservoir 600 to achieve the drainage control.

When the water cover completely closes the outlet, the lower opening / closing plate 230 rotates downward by its own weight to open the inlet 220. In addition, outside air enters through the overflow pipe 510 through the exhaust port 210, and the infiltration water in the buoyancy space 250 is discharged through the inlet port 220.

Next, while the washing water is stored in the reservoir through a ball tap (not shown) for supplying the washing water, the washing machine returns to the state of FIG. 12.

In the present invention, the lower cap 220 is provided with a lower opening and closing plate 230 and the inlet opening 215, which is a long-term leakage of the wash water and overflowing to the outside of the main body washing bowl even when both toilets are blocked Can be prevented. That is, the time until the inlet water is completed to the inlet buoyancy space 250 into the inlet opening 215 is set to the size of the inlet opening so that 3 to 5 times the normal toilet cleaning operation time to close the water cover quickly in normal operation While there is no phenomenon, the buoyancy of the buoyancy space is reduced in the stagnant state or the reverse flow state so that the water cover closes the outlet 505. Detailed description of the operation of the inlet opening 215 is disclosed in Korean Patent No. 10-0897560 of the applicant.

In the present invention, since the urine residual water level is determined according to the specifications of the water cover and other circumstances, a means for controlling this is required. Therefore, the user can install a separate auxiliary tool for adjusting the urine residual level.

19 is a view showing a water cover to which the auxiliary support according to an embodiment of the present invention.

Referring to FIG. 19, when the auxiliary buckle 750 is installed in the connecting line 700, the cover buoyancy space 250 may be quickly exhausted and the urine residual level may be determined at the installation position of the auxiliary buckle. .
