Abstract
A toilet over flow prevention system for installation into a toilet having a tank in fluid communication with a bowl and having a flapper style flush valve and a supplemental water supply. The over flow system includes a flapper solenoid mounted in the tank, for depressing the flapper valve into a closed position, a overflow sensor mounted in the bowl for sensing a over fill condition in the bowl, and a control box communicating with the over flow sensor and the flapper solenoid for operably signalling the flapper solenoid to depress the flapper valve into the closed position in the case of a over fill condition.
Description
- The present invention relates to toilet overflow devices and particularly relates to the devices providing overflow prevention in traditional toilets.
- Presently there is nothing stopping a traditional toilet from continuing to overflow the toilet bowl should there be a blockage in the drain and/or some other reason why the toilet bowl cannot drain. Therefore, flooding can and will occur should there be a blockage in the drain. Overflowing occurs since the toilet tank will continue to refill provided that the user continues to flush the toilet.
- Therefore it is desirable to have a device which will sense an overflow condition and provide for a prevention system which will prevent the toilet bowl from being continually overflowed with water from the toilet tank.
- The toilet overflow prevention system will now be described by way of example only with reference to the following drawings in which:
-
FIG. 1 is a partial cut away schematic perspective view of a traditional toilet with the toilet overflow prevention system deployed therein. -
FIG. 2 is a partial cut away schematic perspective view of the toilet tank filling apparatus together with the toilet overflow prevention system deployed therein, wherein the flapper valve is shown in an open position. -
FIG. 3 is a partial cut away schematic perspective view of the filling components of the toilet system together with the toilet overflow prevention system deployed therein showing the flapper valve in the closed position. - The toilet overflow prevention system will now be described by way of example, only with reference to
FIGS. 1 , 2 and 3 of the attached drawings. - The toilet overflow prevention system shown generally as 100 is shown deployed in a traditional toilet shown generally as 102, wherein the toilet having the traditional features, namely a
toilet tank 110, atoilet bowl 112, afill control 114, adrain stand pipe 116, aflapper valve 118, awater supply 120 as well as asupplemental water supply 122. - All of these components are present in a
traditional toilet 102, wherein water fromwater supply 120 is supplied throughfill control 114 and fillstoilet tank 110 to a certain predetermined level which is controlled byfill control 114. This is usually accomplished through floats and/or other devices which ensure that the water level withintoilet tank 110 is filled to a certain level. - In addition to water entering into
toilet tank 110 during the filling oftoilet tank 110, there is asupplemental water supply 122 which normally diverts a certain portion of the water entering intotoilet tank 110 down intodrain stand pipe 116, such that a certain small portion of water is communicated down intotoilet bowl 112 to ensure that a certain minimum level of water is maintained intoilet bowl 112 after each flush. - Toilet
overflow prevention system 100 is shown deployed in atraditional toilet 102 and includes the following major components namely,flapper solenoid 130, having aram 132 which can impinge upon the top offlapper valve 118. Toiletoverflow prevention system 100 further includes asupplemental solenoid 140 in communication with a supplemental shut offvalve 142 for opening and closing the flow ofsupplemental water supply 122 to drainstand pipe 116. -
Toilet bowl 112 is further fitted with anoverflow sensor 146 which can sense a high water condition withintoilet bowl 112. Overflow sensor 145,flapper solenoid 130, supplemental shut offvalve 142 andsupplemental solenoid 140 are all interconnected and in communication withcontrol wires 148 via acontrol box 150.Control box 150 is shown plugged into a 120 volt alternating current wall outlet but could also be battery operated. -
FIG. 2 showsram 132 offlapper solenoid 130 in a ram up position 166. Ram 132 can travel in avertical direction 164 in order to closeflapper valve 118. InFIG. 2 ,flapper valve 118 is shown in anopen position 160.FIG. 2 is showing the toiletoverflow prevention system 100 in the normal position in which there is not an overflow condition. Supplemental shut offvalve 142 is open in this situation and allows flow of water through supplemental water supply down intodrain pipe 116 as is normal during normal operation oftoilet 102. - Should an overfill condition in the
toilet bowl 112 be detected byoverflow sensor 146 which is located somewhere withintoilet bowl 112, it will send a signal to controlbox 150 which in turn will send signals to flappersolenoid 130,supplemental solenoid 140 as well as supplemental shut offvalve 142, thereby causingflapper solenoid 130 to extendram 132 into the ram down position 168 which impinges upon the top offlapper valve 118 as shown inFIG. 3 forcibly closingflapper valve 118 into a closedposition 162 as shown inFIG. 3 . In addition,supplemental solenoid 140 will turn off supplemental shut offvalve 142 thereby preventing any further flow of supplemental water throughsupplemental water supply 122 and thereby prevent any additional water draining intodrain stand pipe 116. In other words, all of the potential water sources are cut off and shut down and no further water will flow fromtoilet tank 110 intotoilet bowl 112 thereby preventing any further overflow conditions. - A person skilled in the art will note that toilet
overflow prevention system 100 deployed in aconventional toilet 102 will prevent continuation of overflow conditions intoilet bowl 112 when a high water level is detected byoverflow sensor 146. This is accomplished by sending control signals to flappersolenoid 130, thereby loweringram 132 into a ram down position 168 forcibly closingflapper valve 118 as well as sending control signals tosupplemental solenoid 140 thereby shutting off supplemental shut offvalve 142 which in turn will close offsupplemental water supply 122 to drainstand pipe 116. - In addition there is a
button 190 shown inFIG. 1 which is a manual override which will allow the user to resetflapper solenoid 130 as well assupplemental solenoid 140 after the highwater overflow sensor 146 senses a high water condition. Thismanual override button 190 can be used any time to override the toilet overflow prevention system by inactivating the solenoids putting the control system back to wheretoilet 102 will operate as would normally operate without the toilet overflow prevention system in place.Button 190 for example could be set up to inactivate the solenoids when pushed once and to activate the solenoids when pushed twice.Button 190 could be located in a concealed position or under some ornamental device such as a doll or other device which could conceal the location ofbutton 190. - It should be apparent to persons skilled in the arts that various modifications and adaptation of this structure described above are possible without departure from the spirit of the invention the scope of which defined in the appended claim.
