Publication number: 20220228354Abstract: A system for preventing overflow of a toilet includes a sensor, a processor and an actuator. The sensor senses a parameter caused by fluid dynamics within the toilet during a flush cycle. The parameter may involve vibration, sound, pressure, fluid flow rate or other detectible characteristics of the toilet. The processor uses information regarding the parameter that is gathered by the sensor to evaluate the condition of the flush cycle to determine if an impeded flush condition exists. In the event of an impeded flush condition, the processor directs the actuator to close a valve, which may be the toilet flapper valve in some embodiments. Also disclosed are methods for preventing toilet overflow, detecting an impeded flush condition and calibrating the system.Type: ApplicationFiled: April 6, 2022Publication date: July 21, 2022Inventors: Kevin Bowcutt, Ahmed Shishegar, Matthew Ibarra, Daniel Corbin, Dennis Repp, Robert M. Connell, Oscar Dufau, Gregory Blake, Sam Iravantchi

Patent number: 5042095Abstract: An apparatus is provided which enables a container of cleaning fluid to lie in a water closet and dispense cleaning fluid solely into the toilet bowl rather than into the water closet. The apparatus includes a storage chamber (54) for holding granules of a chemical that dissolves in water to create cleaning fluid, and a transfer chamber (64) through which water flows from a refill valve outlet (40) into a standpipe (44) that leads to the toilet bowl, at each flushing of the toilet. The transfer chamber is coupled to the storage chamber so that cleaning fluid can migrate from the storage chamber (54) into the transfer chamber (64), and yet during each flushing the water from the refill outlet primarily sweeps out cleaning fluid in the transfer chamber. An anti-siphon device (74) between the refill valve outlet and the cleaning fluid dispensing apparatus includes a check valve, and a chamber that surrounds the check valve.Type: GrantFiled: November 3, 1987Date of Patent: August 27, 1991Assignee: Fluidmaster, Inc.Inventors: Adolf Schoepe, Oscar Dufau

Patent number: 5025826Abstract: A faucet handle assembly is described for replacing a handle on a faucet valve stem, which can mount on a wide variety of types of stems. The assembly includes a pair of jaws (30, 32, FIG. 1) having inner surfaces for engaging opposite sides of the periphery (22) of the valve stem and having outer camming surfaces (42, 43) that can be pushed together. The assembly also includes a faucet handle (12) with a hole in the top for passing a screw (28) that screws into a threaded hole of the valve stem, and having a cavity (44) for receiving the jaws. The cavity has camming surfaces (54, 56) that engage the jaw camming surfaces, so as the screw is tightened the jaws are pressed tightly against the valve stem peripheral surface.Type: GrantFiled: September 4, 1990Date of Patent: June 25, 1991Inventors: Adolf Schoepe, Oscar Dufau

Patent number: 4938245Abstract: A toilet refill valve is described for refilling a water closet after each flushing, which produces minimal noise during the refill process. The valve includes a valve device which can open to pass water to a vertical outlet tube that empties into the bottom of the water closet. An anti-siphon air tube near the top of the outlet tube has an upper end open to the atmosphere and a lower end facing downwardly along the outlet tube. A restriction in the outlet tube below the air tube, causes water to fill the outlet tube and at least the bottom of the air tube for a water inlet pressure of at least 20 psi. The water at the bottom of the air tube prevents air from being dragged into the downwardly facing air tube, to avoid the noise that would result from such air flowing through the air tube and bubbling out of the bottom of the outlet tube.Type: GrantFiled: September 25, 1989Date of Patent: July 3, 1990Assignee: Fluidmaster, Inc.Inventors: Adolf Schoepe, Oscar Dufau
