- The toilet has been essential home equipment for body waste since being invented. The flapper valve is adapted to open for releasing water from a toilet water tank and to close for the purpose of refilling water in the toilet water tank. A wire or a rod opens the flapper valve by pulling up when a user turns a trip handle, then the flapper valve is closed by water pressure.
- A prior toilet having a toilet water tank and a flapper valve has a problem that the flapper valve is not closed accurately for some reasons, and water leaks through a gap between the flapper valve and a flapper valve seat that causes water waste.
- The reason for the above-mentioned problems is that the water pressure is low to close the flapper valve exactly, or the wire is not loose enough to close the flapper valve.
- This invention provides a solution for related problems by providing a float pusher that supports closing a flapper valve properly, and the float pusher is adapted to move up and down in the toilet water tank by buoyancy force.
- The present invention contrives to solve a problem that has not address by the prior art.
- An object of the invention is to provide a toilet having a toilet water tank, a flapper valve and a float pusher that supports closing a flapper valve properly.
- To achieve the above object, the present invention provides a toilet having a toilet water tank and a flapper valve. The toilet includes a float pusher that is adapted to support closing a flapper valve properly and move up and down in the toilet water tank by buoyancy force, a vertical guide that guides the float pusher in moving up and down along the vertical guide and the flapper valve that is adapted to open for releasing water from a toilet water tank and to close for the purpose of refilling water in the toilet water tank. In an embodiment, the vertical guide for the float pusher is an overflow pipe of the toilet.
- The float pusher includes a through hole, a bottom surface, a top surface, an outer surface connecting the top surface and the bottom surface. The float pusher has a cylindrical body and is assembled to move along the vertical guide. The bottom surface of the float pusher may have a flat surface, a concave surface or a convex surface. The through hole is provided between the top surface and the bottom surface, and a diameter of the through hole is larger than a diameter of the vertical guide.
- A water recess adapted to contain water is provided on the top surface and the float pusher pushes to close properly the flapper valve by the force of its own weight and a weight of contained water in the water recess at a lower level of water. The water recess of the through hole may include a first annular step that is adjacent to the top surface of the float pusher.
- In another embodiment, the toilet includes a cross bracket that is attached to the toilet water tank and includes a guide rod that is attached to the cross bracket. The position of the guide rod on the cross bracket is adjustable. The vertical guide for the float pusher is the guide rod.
- The through hole is located at the center of the top surface. The through hole may be located offset from the center of the top surface, and in this case of that the toilet water tank has a guide wall that surrounds the outer surface of the float pusher. The through hole may include one or more longitudinal projected lines or one or more flat portion for preventing jamming.
- The advantages of the present invention are: (1) the toilet helps to close the flapper valve properly and early; (2) the toilet prevents water leakage by an unclosed flapper valve; and (3) the toilet fits any type of the toilet water tank.

FIG. 15 shows afloat pusher 10 and avertical guide 12 and a flapper valve according to present invention. The toilet according to the present invention includes a toilet water tank 14 (refer toFIG. 12 ) Thefloat pusher 10 that is adapted to support closing theflapper valve 16 properly and move up and down in thetoilet water tank 14 by buoyancy force, thevertical guide 12 that guides thefloat pusher 10 in moving up and down along thevertical guide 12 and theflapper valve 16 that is adapted to open for releasing water from atoilet water tank 14 and to close for the purpose of refilling water in thetoilet water tank 14. In one embodiment, thevertical guide 12 for the float pusher is anoverflow pipe 18 of the toilet. -
FIGS. 1 and 2 show that thefloat pusher 10 includes a throughhole 20, abottom surface 22, atop surface 24, anouter surface 26 connecting thetop surface 24 and thebottom surface 22. Thefloat pusher 10 has a cylindrical body and is assembled to move along thevertical guide 12.FIGS. 9-11 show that thebottom surface 22 of thefloat pusher 10 has aflat surface 28, aconcave surface 30 or aconvex surface 32. The various shapes of thebottom surface 22 provide efficient operation of thefloat pusher 10 in applications having varying geometry around theflapper valve 16. Thethrough hole 20 is provided between thetop surface 24 and thebottom surface 22, and a diameter of the throughhole 20 is larger than a diameter of thevertical guide 12. The gap between the throughhole 20 and thevertical guide 12 is determined to provide smooth movement of thefloat pusher 10 and thevertical guide 12, and to adjust the speed of the down movement of thefloat pusher 10. - A water recess 34 that is adapted to contain water is provided on the
top surface 24. Thefloat pusher 10 pushes to close properly theflapper valve 16 by the force of its own weight and a weight of contained water in the water recess 34 at a lower level of water. InFIG. 1 the water recess 34 of the throughhole 20 includes a firstannular step 36 that is adjacent to thetop surface 24 of thefloat pusher 10. -
FIG. 12 shows another embodiment, in which the toilet includes across bracket 38 that is attached to thetoilet water tank 14 and aguide rod 40 that is attached to thecross bracket 38 as thevertical guide 12. The position of theguide rod 40 on thecross bracket 38 is adjustable. -
FIGS. 1-4 and 9-15 show that the throughhole 20 is located a center of thetop surface 24 of thefloat pusher 10.FIGS. 5-8 show that the throughhole 20 is located an offset from the center of thetop surface 24. As shown inFIG. 6 , the toilet water tank has aguide wall 42 that surrounds theouter surface 26 of thefloat pusher 10. Theguide wall 42 helps the float pusher not to jam with theoverflow pipe 18 by guiding theouter surface 26 of thefloat pusher 10. Thefloat pusher 10 is movable along theguide wall 42. - The through
hole 20 includes one or more longitudinal projected lines 44 (refer toFIG. 16 ) or includes one or more flat portion 46 (refer toFIG. 17 ) for preventing jamming. - Part of the top surface of the float pusher may have different height from the remaining portion of the top surface of the float pusher and the through hole of the float pusher may be lower than the outer surface of the float pusher in order to prevent interference with existing parts of the toilet. The through hole is provided to have various diameters to accommodate different diameters of the overflow pipe or to prevent interference with protrusions on the overflow pipe.
- The float pusher may further include a lid, and the lid has one or more through holes for water to enter. A top of the lid may have a flat surface, a concave surface or a convex surface.
- The float pusher may include one or more pieces that are assembled with each other with pins or recesses. By adjusting gaps between the pieces, the size of the float pusher is adjustable.
- In case the refill water supply tube is positioned above the float pusher, water ejected from the refill water supply tube hits the float pusher and facilitates moving of the float pusher.
- In case the overflow pipe in the toilet water tank is close to the inside wall of the toilet water tank, part of the through hole is open to prevent jamming with the inside wall.
- Diameter and height of the guide wall are determined so that the float pusher's movement is not interfered with existing toilet parts.
- While the invention has been shown and described with reference to different embodiments thereof, it will be appreciated by those skilled in the art that variations in form, detail, compositions and operation may be made without departing from the spirit and scope of the invention as defined by the accompanying claims.
