Description
- This application claims priority to U.S. Application Ser. No. 61/326,265, filed Apr. 21, 2010, herein incorporated by reference in its entirety.
- 1. Field of the Invention
- This invention relates generally to toilets and, in one particular embodiment, to an assembly for preventing the toilet bowl from overflowing onto the bathroom floor.
- 2. Technical Considerations
- Almost everyone has at one time or another had to deal with the problem of a clogged toilet bowl. Toilet bowls can become clogged for many reasons. For example, the discharge line can become obstructed due to excessive waste matter, toilet tissue, or the flushing of inappropriate articles. The undesired result is typically a toilet bowl overflow, which can lead to unsanitary conditions or even property damage caused by the overflowing water.
- Therefore, it would be desirable to provide a device that can detect and prevent a toilet bowl overflow.
- A toilet overflow preventer comprises an overflow sensor configured to extend into the interior of a toilet bowl. An electrical power source is connected to the overflow sensor. An actuator assembly (which can be located inside the toilet bowl tank) is connected to the overflow sensor such that activation of the overflow sensor causes the actuator assembly to close the toilet flush valve.
- Another toilet overflow preventer comprises an overflow sensor configured to extend into the interior of a toilet bowl. The overflow sensor comprises a housing having a liquid-porous bottom with a switch located inside the housing. A battery is in electrical communication with the overflow sensor. An actuator assembly is connected to the battery and the overflow sensor. The actuator assembly comprises an actuator having a movable actuator arm, for example, moveable from a first position not in contact with the toilet flush valve to a second position in contact with the toilet flush valve based upon a signal from the overflow sensor switch.
- An exemplary overflow preventer of the invention will be described with reference to the following drawing figures wherein like reference numbers identify like parts throughout.
-
FIG. 1 is front, elevated view of a conventional toilet incorporating an overflow preventer of the invention; -
FIG. 2 is a bottom view of a sensor housing of the invention; and -
FIG. 3 is an interior view of a sensor housing of the invention. - As used herein, spatial or directional terms, such as “left”, “right”, “inner”, “outer”, “above”, “below”, and the like, relate to the invention as it is shown in the drawing figures. However, it is to be understood that the invention can assume various alternative orientations and, accordingly, such terms are not to be considered as limiting.
- A
conventional toilet 10 is shown inFIG. 1 . The components and operation of a conventional toilet will be well understood by one of ordinary skill in the art and, therefore, will not be described in detail. Thetoilet 10 components will first be described and then the overflow preventer of the invention will be described. Thetoilet 10 has aseat portion 12 comprising abowl 14 having arim 16. A waste drain, typically referred to as asiphon jet 18, is located at the bottom of thebowl 14. Thesiphon jet 18 leads to a siphon (waste discharge) at the back of thebowl 14. Atank 20 is located above theseat portion 12 and has a hollow interior configured to hold water. Afiller tube 24 having afiller float 26 and a filler valve (28) is located in the tank. Thefiller tube 24 is connected to a source of water via thefiller valve 28. Thefiller valve 28 is in operational connection with thefiller float 26. Anoverflow tube 30 is also located in the interior of thetank 20 and has a hollow interior in flow communication with thetoilet bowl 14. - A
drain 32 is located in the interior of thetank 20 and is in flow communication with the interior of thebowl 14. Aflush valve 34, such as a conventional flapper valve, is configured to close-off thedrain 32. Theflush valve 34 is connected to ahandle 36, such as by alever 38 having achain 40 connected to theflush valve 34. - Under normal circumstances, when the
toilet 10 is to be flushed, thehandle 36 is depressed. This lifts theflush valve 34 and allows water from the interior of thetank 20 to flow into thebowl 14 through the drain 9 and flush material out of thebowl 14 through thesiphon jet 18. As the water leaves thetank 20, thefiller float 26 descends on thefiller tube 24. This activates thefiller valve 28 to allow water flow into the interior of thetank 20 through thefiller tube 24. As the water begins to refill thetank 20, thefiller float 26 rises on thefiller tube 24 until it rises to a position to close thefiller valve 28 and stop water flow into thetank 20. - Should the
siphon jet 18 become clogged, such as by the insertion of children's toys or other inappropriate objects, water entering thebowl 14 through thedrain 32 will rise in thebowl 14 and then overflow onto the bathroom floor. - However, an overflow preventer of the invention can prevent this undesirable occurrence. An exemplary overflow preventer 50 of the invention is shown in
FIG. 1 . The components of the overflow preventer 50 will first be described and then the operation of the overflow preventer 50 will be described. The overflow preventer 50 includes anoverflow sensor 52 configured to extend into the interior of thebowl 14. In the illustrated embodiment, theoverflow sensor 52 is attached to therim 16 of thebowl 14, such as by a hook orhanger 54. Theoverflow sensor 52 includes ahousing 56 having a liquid permeable bottom 58 (seeFIG. 2 ). Thebottom 58 can either be completely open or can have a screen or mesh across the opening to allow liquid (water) to enter but prevent material entering thehousing 56. Theoverflow sensor 52 can include a switch 60 (seeFIG. 3 ), such as a conventional two position limit switch or arm switch. One switch particularly suitable for the present invention is a “momentary push button switch” (part number 275-1547) commercially available from Radio Shack. - The overflow sensor 52 (i.e., the switch 60) is connected to an
electrical power source 62, such as by a cable orwire 64. While in the broad practice of the invention theelectrical power source 62 can be any conventional electrical source, in one particular embodiment, theelectrical power source 62 includes a battery, such as a nine-volt battery. The use of such a battery rather than electricity from a conventional wall outlet decreases the possibility of electrical shock to a user. - An
actuator assembly 70 is connected to theelectrical power source 62 via a cable orwire 71. Theactuator assembly 70 is also connected to theoverflow sensor 52, for example, by a cable or wire. In the illustrated embodiment, theactuator assembly 70 is positioned in the interior of thetank 20 and includes amovable actuator 72 having anactuator arm 74. Theactuator 72 can be of any conventional type, such as an electrical actuator. Theactuator arm 74 can be a straight, telescoping arm or can be an articulated arm, as shown inFIG. 1 . In the illustrated embodiment, theactuator assembly 70 is connected to theoverflow tube 30 by conventional bands or straps 76. However, it is to be appreciated that theactuator assembly 70 need not be connected with theoverflow tube 30 but could be positioned anywhere in the interior of thetank 20 to operate as described below. Operation of the overflow preventer 50 will now be described. - Should the siphon
jet 18 become clogged and the water begin to rise in thebowl 14, the water enters the bottom 58 of theoverflow sensor housing 56 and actuates the switch 60 (such as by raising the lever arm of the switch from an inactive to an active state). The signal from theswitch 60 activates theactuator 72. Upon activation, theactuator 72 extends the actuator aim 74 from the position shown inFIG. 1 downwardly to press against the top of theflush valve 34 to press theflush valve 34 downwardly to close thedrain 32. This prevents water from the interior of thetank 20 flowing through thedrain 32 and into thebowl 14 and prevents the water in thetoilet bowl 14 from overflowing onto the bathroom floor. The water fills up thetank 20 until thefiller float 26 rises to a position to close thefiller valve 28 and stop the flow of water into thetank 20. - It will be readily appreciated by those skilled in the art that modifications may be made to the invention without departing from the concepts disclosed in the foregoing description. Accordingly, the particular embodiments described in detail herein are illustrative only and are not limiting to the scope of the invention, which is to be given the full breadth of the appended claims and any and all equivalents thereof.
