A flush toilet includes a bowl, a tank coupled to the bowl, a flush valve positioned within the tank, and a flush device configured to initiate a flush cycle. The automatic toilet further comprises an electronic sensing assembly having a sensing member positioned on the bowl for detecting an overflow condition of the bowl, an overflow device operably coupled to the flush device, and a controller in electronic communication with the electronic sensing assembly and the overflow device for controlling the flush device in response to a condition of the toilet.

An intermittent fluid delivery system includes a fill tank and a batch tank which is connected to the fill tank via a first pump and a first hose. The fill tank holds a first quantity of fluid. The batch tank holds a second quantity of fluid, which is lesser than the first quantity. The first pump delivers fluid from the fill tank to the batch tank. A second pump delivers fluid from the batch tank to a receiving tank.

Toilet flappers having an adjustable length cord are disclosed. For example, a toilet flapper may include a frame with a guide structure. A float is connected to a bottom surface of the frame. A cap is connected to a top surface of the frame. A retractable cord reel is housed between the cap and the frame. During installation of the toilet flapper, a user can grab a hook attached to the end of the cord and pull enough of the cord out of the retractable cord reel and through the guide structure so that the user can attach the hook to, for example, a flush lever. In some embodiments, the toilet flapper includes a locking mechanism that impedes the cord from retracting back into retractable cord reel or from being pulled out of retractable cord reel by the user.

A self-cleaning toilet has: a toilet, a cleaning device, a solenoid valve and a blocking member. The toilet has a sitting toilet seat and a water tank. The sitting toilet seat is formed with a urinal, and one end of the urinal has an enlarged opening to form a seat, and the urinal tapers from the seat to the other end to form a drain elbow. The water tank is connected to the toilet with an outlet pipe, and the water tank is connected with an input pipe, a cleaning device is set in the toilet with a controller, and the controller is connected with a plurality of the ultrasonic transducers and a full water level sensor, The ultrasonic transducers are fixed on the inner wall of the urinal. The solenoid valve is connected to the input pipe, and a blocking member is connected to the drain elbow.

A toilet includes a water storage tank, a bowl including a waste receiving basin that includes an upper rim and at least one toilet bowl aperture in a side wall of the waste receiving basin, a water supply plenum operable to receive water from the water tank and channel the water to the bowl, a primary drain operable to connect the basin and a sewer pipe, and a secondary drain fluidly operable to connect the toilet bowl aperture to the sewer pipe and operable to drain the water from the bowl. The secondary drain is separate from the primary drain and includes an auxiliary aperture fluidly connecting the secondary drain to the water supply plenum and operable to drain the water from the plenum. The toilet bowl aperture and the auxiliary aperture are operable to permit the water to bypass the primary drain when the primary drain is clogged.

A toilet having a first-magnet secured to the terminal end of the toilet's flush-arm and a second-magnet secured to the toilet's lid such that when the lid is in its open or up position, the two magnets align preventing the flush-arm from rotating upward to cause the toilet to flush. Conversely, when the lid is down and the two magnets are separated, the flush-arm can be rotated upward causing the toilet to flush. In another example, a magnet-attracting component, such as iron, cobalt or nickel, can be substituted for one of the magnets. A kit for retrofitting an existing toilet is also disclosed.

A flush toilet includes a bowl, a tank coupled to the bowl, a flush valve positioned within the tank, and a flush device configured to initiate a flush cycle. The automatic toilet further comprises an electronic sensing assembly having a sensing member positioned on the bowl for detecting an overflow condition of the bowl, an overflow device operably coupled to the flush device, and a controller in electronic communication with the electronic sensing assembly and the overflow device for controlling the flush device in response to a condition of the toilet.

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.

An apparatus includes a housing, a valve located within the housing, the valve being adapted to fluidly connect to an external toilet and an external water supply that provides water to the toilet, and a water sensor. The valve includes an open position, in which the water supply is enabled to supply water to the toilet, and a closed position, in which the external water supply is prevented from supplying water to the toilet. The water sensor is electrically connected to the valve and is operable between an inactivated state, in which the water sensor is substantially dry, and an activated state, in which the water sensor is subjected to an amount of water. When the water sensor is in its activated state, the valve is moved to its closed position to cut off the water supply to the toilet.

The present disclosure describes toilet flappers having an adjustable length cord. For example, the present disclosure describes a toilet flapper having a frame with a guide structure. A float is connected to a bottom surface of the frame. A cap is connected to a top surface of the frame. A retractable cord reel is housed between the cap and the frame. During installation of the toilet flapper, a user can grab a hook attached to the end of the cord and pull enough of the cord out of the retractable cord reel and through the guide structure so that the user can attach the hook to, for example, a flush lever. In some embodiments, the toilet flapper includes a locking mechanism that impedes the cord from retracting back into retractable cord reel or from being pulled out of retractable cord reel by the user.
