The present invention relates to a water cover for adjusting the drainage amount of the toilet bowl, and more particularly to a toilet cover for adjusting the drainage amount that can selectively adjust the drainage of the washing water contained in the water tank.

The toilet is composed of a water tank and a toilet main body installed at the lower part of the tank to receive and store the washing water through the ball tap, and the washing 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. It is.

Such a conventional discharge structure is to discharge all of the washing water stored in the tank irrespective of the type of stool, there is 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 washing water in two stages, the upper part of the water cover to open the drain pipe by rotating upward about one side of the drain pipe by the upward pulling force By opening the buoyancy space of the water cover to lose the buoyancy of the water cover, there is a method of providing a separate buoyancy 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 opening And packing as a basic configuration, 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, 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 a short time opening, 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, and the control means of the opening and closing means of the exhaust port according to the operation of the pull string are supplemented with a magnet in the existing spring, resulting in inaccurate opening and closing time. The malfunction is 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.

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, thus interfering with the reservoir wall and aging of the exhaust hose connection part. There is a problem that increases the possibility of leakage.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide a toilet cover for adjusting the amount of drainage that can stably adjust the magnitude of the drainage and prevent leakage of the washing water.

In order to achieve the above object, the toilet cover for adjusting the drainage amount of water according to the present invention has a cylindrical guide space formed at an inclined upper portion, and a cover having a ball guide and a ball stopper at a lower portion of the guide space extending therefrom; It is accommodated in the guide space of the cover can move up and down a certain distance, the hook having a ring portion at the bottom; And a lower cap coupled to a cover and a cover seal in a state interposed therebetween to form a buoyancy space. The lower cap includes an exhaust port located in front of the cover packing lower part so as to connect the buoyancy space to the outside, and is symmetrical with the exhaust port. It is provided with a vent positioned in the bottom, the inlet is located at the bottom, the inner buoyancy space of the exhaust port is provided with an inclined support on which a ball having a larger diameter than the exhaust port is arranged.

In the present invention, the ball can be moved by rolling between the front of the exhaust port and the ball stopper in the direction of gravity and inclination angle along the inclined surface of the inclined support.

In the present invention, the hook is a protrusion stopper formed on one side of the hook is fitted into the groove formed in the guide space of the cover can move a predetermined distance up and down.

In the present invention, the buoyancy adjustment buckle may be coupled to the water cover.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 is a perspective view, a cross-sectional view and an installation cross-sectional view showing a water cover for adjusting the toilet drainage amount according to the present invention. The present invention distinguishes the feces mode from the urine mode by adjusting the buoyancy of the water cover.

1 and 2, the water cover is assembled with a cover 100 and a hemispherical lower cap 200 in a state where the cover packing 300 is interposed, and a buoyancy space 250 is formed therein. The front of the cover 100 is formed so that the cylindrical guide space 110 for accommodating the hook is inclined upwardly, the hook 400 is accommodated in the guide space 110.

The lower portion of the hook 400, the inclined ring portion 405 is formed, the upper portion is formed with a connector 410 is fastened to the connecting line. O-ring 415 is interposed between the guide space 110 and the hook 400 to prevent leakage and leakage of the buoyancy space 250 and the outside of the water cover. At the end of the guide space 110, the compression spring 420 is inserted against the jaw 425 formed in the hook is compressed in a certain amount so as to have a predetermined initial force. The hook 400 is fitted into the protruding stopper 430 formed on one side and the groove 115 formed in the guide space 110 of the cover, and is assembled to allow only a vertical movement of a predetermined distance and not be pushed by the initial force of the spring 420. .

The lower cap 200 has a buoyancy space 250 and an exhaust port 205 penetrating the outside under the cover packing 300. Exhaust port 205 is located under the cover packing 300 has an effect that does not occur leakage due to foreign matter jamming, aging, and the like. A ball 230 having a larger diameter than the exhaust port 205 is disposed on the inclined support 210 on the inner buoyancy space 250 side of the exhaust port 205. An inlet 215 penetrating to the outside is formed at the lowermost portion of the lower cap, and a vent 220 is formed in a direction of rotation axis opposite to the exhaust port 205.

A side of the cover 100 is a pair of fixing ring 105 which is hinged to the rotating shaft of the main body is formed, the stopper 130 is disposed on the upper cover between the fixing ring 105. The cover 100 has a pair of left and right ball guides 120 and a ball stopper 125 formed at positions corresponding to the inclined supports 210 of the lower cap 200 and restrained in the space formed therebetween ( 230 may move along the inclined surface of the inclined support 210 by rolling between the front of the exhaust port 205 and the stopper 125 in the direction of gravity and inclination angle. In the position where the ball 230 is blocking the exhaust port 205, the hook portion 405 of the hook 400 accommodated in the guide space 110 of the cover is located on the side of the ball 230, but in the normal state the ball 230 Does not touch).

Referring to FIG. 3, the body 500 in which the above-described water cover is installed is installed in the reservoir 600 through the packing 650, and a discharge port 505 is formed in a cylindrical shape so as to penetrate the reservoir in the center thereof. Overflow pipe 510 that rises above the normal level of the reservoir 600 is connected to a predetermined distance. The overflow pipe 510 is disposed with a rotating shaft 515 which is a rotation center when the water cover is operated. The fixing ring 105 of the water cover is fitted and hinged to the rotating shaft 515 of the main body, and the cover packing 300 of the water cover contacts the upper portion of the outlet 505 to prevent the washing water from leaking into the outlet 505. There is a contact surface 520 of the discharge port in contact with the cover packing 300 is formed in an inclination that the overflow pipe side is high and the opposite side is lowered. At this time, since the exhaust port 205 is not exposed to the washing water side of the water storage tank at the bottom of the water cover packing 300, there is no fear of leakage of the washing water.

The washing water retained by the gap between the hook 400 and the guide space 110 is prevented from leaking by the O-ring 415, and the connecting line 700 connected to the top of the hook 400 is operated by a hand lever (not shown). Is connected to the link.

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

First, when you want to wash the stool requiring a large amount of water, such as feces, rotate the control lever (not shown) at a small angle to pull the pull string connected thereto.

3 to 6 are views showing a large amount of washing water discharged state according to an embodiment of the present invention.

Referring to FIG. 3, the washing 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 is formed in the body 500 through the vent 220. Open to the overflow pipe 510 is in the atmospheric pressure state. The ball 230 is positioned below the inclined surface 211 of the inclined support 210 to block the exhaust port 205.

Referring to FIG. 4, when the user operates the hand lever, the connection line 700 is pulled and the hook 400 connected to the connection line 700 is pulled. By the way, the hook 400 is not moved by the spring 420 having an initial force to lift the entire water cover. When the water cover is lifted, the washing water stored in the reservoir 600 begins to be discharged to the outlet 505, and at this time, some of the washing water penetrates into the buoyancy space 250 of the water cover through the vent 220 and the inlet 215. . Subsequently, the water cover is rotated upward by itself by buoyancy by air in the buoyancy space 250 to open the water cover, and the washing water flows out to the outlet 505.

Referring to FIG. 5, when the water cover is completely opened, the stop jaw 130 stops by touching the overflow pipe 510. At this time, the hand lever has already stopped pulling the credit mode.

In the state where the water cover is completely open, the washing water is continuously discharged to the outlet 505, and acts as a closing force to the water cover downward by the flow rate of the washing water discharged. However, due to the air buoyancy by the buoyancy space 250 of the water cover, the water cover maintains an open state for a certain period of time.

The ball 230 is positioned in front of the downward inclined surface of the inclined support 210 even after the water cover is completely opened to keep the exhaust port 230 closed. Reference numeral 'a' may be designed to be about 15 ° to the inclination inclination of the ball 230 in the open state of the water cover.

The infiltration water penetrating into the inlet port 215 and the vent hole 220 has a very small water head difference h ₁ between the two holes 215 and 220 in the open state, and thus the surface tension and buoyancy space generated at the contact surface between the hole and water and air. Penetration into the buoyancy space 250 is stopped by the repulsive force of the trapped air.

Referring to FIG. 6, when the water level is lowered to the water cover rotation shaft 515 while the washing water is continuously discharged to the outlet 505, the buoyancy of the water cover is reduced because the buoyancy space 250 floats on the surface of the water, and water The cover descends along the surface and begins to close. That is, when the lower cap 200 of the water cover enters into the contact surface 520 of the main body, the gap through which the washing water flows out becomes narrow, thereby increasing the action of the closing force due to the flow rate of the discharge washing water, thereby remaining in the buoyancy space 250. Wins and the water cover is closed. When the water cover is closed, some of the infiltration water of the buoyancy space 250 flows into the inlet 215, some traces may remain in the surface action.

When the water cover is closed, the washing water returns to the normal state again in FIG. 5 while being stored in the reservoir.

7 to 10 are views showing a small amount of washing water discharged state according to the first embodiment of the present invention. If you want to wash the toilet that requires a small amount of washing water by rotating the lever at a large angle pulls the connecting line 700 connected thereto. The initial state is the same as that of Figs. The pulling force of the hand lever in the urine mode acts longer than in the above-described stool mode, so that the connecting line 700 continues to be pulled even when the stopper 130 of the water cover touches the overflow pipe 520 of the main body and is completely open. to be.

Referring to FIG. 7, in the urine mode, the pulling line is compressed by applying a force above the initial force set in the spring 420 of the hook 400. At this time, as the hook is raised and the ball is lifted by the hook 405 of the hook, the ball is rolled down to the ball stopper 125 at the inclination of the rear downward inclination angle β of the inclined support 210. As the ball rolls to open the exhaust port 205 blocked by the ball, air inside the buoyancy space 250 is discharged in the form of bubbles. At the same time, a portion of the washing water continues to flow from the inlet 215 and the vent 220 side. That is, the washing water continuously enters the buoyancy space 250 by the head difference h ₂ between the inlet 215 and the exhaust port 220 and the head difference due to the surface tension of the exhaust port 205, thereby reducing the buoyancy.

Referring to FIG. 8, the hook 400 is lowered by the restoring force of the spring 420 after the pulling operation of the hand lever is completed. However, since the ball 230 is inclined downward behind the inclined surface of the inclined support 210. Maintain that position.

Air in the buoyancy space 250 of the water cover is continuously discharged in the form of bubbles through the exhaust port 205, the infiltration water through the inlet 215 and the vent 220 to the head (h ₃ ) by the surface tension of the exhaust port Continues to increase.

When the buoyancy due to the air remaining in the buoyancy space 250 is lower than the closing force due to the flow rate of the washing water discharged from the reservoir, the water cover is gradually lowered to start the closing operation.

Referring to FIG. 9, when the water cap is slowly closed, the lower cap 200 enters the contact surface 520 of the main body 500, and the gap from which the washing water exits is narrowed, and the action of the closing force due to the flow rate of the washing water is discharged. As it grows, the water cover closes quickly.

The ball 230 is located on the downward slope of the rear of the inclined support 210, and is inclined forward by the inclination angle δ by the closing angle of the entire water cover, so that the ball rolls and moves to the front inclined plane.

Referring to FIG. 10, when the water cover is completely closed, the ball 230 rolls toward the exhaust port 205 to block the exhaust port 205. The outlet 505 generates a vacuum while the washing water is completely discharged immediately after the water cover is closed. At this time, the outside air is sucked through the overflow pipe 510 to release the vacuum.

The infiltration water inside the buoyancy space 250 of the water cover is quickly drained through the inlet 215 by the infiltration air and the self-inflow flowing through the overflow pipe 510 and the vent 220, the urine mode is completed. In the urine mode, the water cover has less washing water discharged from the reservoir than in the feces mode, thereby saving water.

11 to 13 are views showing a discharge state of a small amount of the washing water according to the second embodiment of the present invention. In contrast to the first embodiment, the buoy 800 may be attached to the water cover or water cover connecting line 700 to adjust the urine level according to its position. In the case where the accessory 800 is additionally attached, the initial state is the same as in FIG. 9, which is the first embodiment. However, for the purpose of designing the diameters of the exhaust port 205 and the inlet port 215 to be larger than those in the first embodiment, the permeate water penetrates into the buoyancy space before the appropriate small variable position.

Referring to FIG. 11, although the infiltration water is completely penetrated into the buoyancy space 250, the buoyancy force of the residual air is smaller than the closing force due to the flow rate of the discharge washing water, but the water cover is opened by the buoyancy force of the buoy 800. The state is maintained.

Referring to FIG. 12, as the washing water is discharged, the water level is lowered so that the buoy 800 is exposed to the water and the buoyancy of the buoy is gradually reduced. When the buoy 800 is exposed to the degree of locking by the weight (h _b ), the buoyancy is completely eliminated, and the cover 800 slowly starts to close due to the closing force caused by the flow rate of the discharge washing water.

Referring to FIG. 13, when the water cap is slowly closed and the lower cap 200 enters the contact surface 520 of the main body, the gap from which the washing water is discharged is narrowed to increase the action of the closing force due to the flow rate by the discharge washing water. The cover closes rapidly.

When the water cover is completely closed, the urine mode ends as described in FIG. 10.

The present invention described above is not limited to the above-described drawings and detailed description, and various modifications and changes made by those skilled in the art without departing from the spirit and scope of the present invention described in the claims below. Of course, it is also included within the scope of the present invention.

As described above, the toilet cover for adjusting the toilet drainage capacity of the present invention is to clean the exhaust port during the period when the cover is closed to store the cleaning water by the exhaust port for discharging air in the buoyancy space to reduce the buoyancy to store the washing water Since it is not exposed to the water side, no leakage occurs due to foreign matter jamming or aging.

In addition, the present invention by installing the O-ring on the operating portion of the hook is excellent in stability and durability by watertight and foreign material does not occur.

In addition, if the operation of the hand lever is momentarily applied, the ball moves and maintains its position until the lid is closed, so that the exhaust is constant and the buoyancy reduction amount is uniform, thereby ensuring stable operation.
