Systems and methods that provide enhanced capability for toilets and bathrooms in general by adding feature sets such as user weighing, leak detection, enhanced toilet cleaning/deodorizing and other features, connected over networks to user devices and servers, creating a complete bathroom ecology where users have direct and remote control and access to system functions and data, and server based bathroom support applications provide a wide range of capabilities including user control and readout of toilet systems functions, bathroom condition, supply levels, and health data.

The invention relates to a cistern, in particular an in-wall cistern, for a toilet or urinal, with a drain valve which has a closure body which can be lifted from a closed position into a flushing position. The closure body is designed as an overflow pipe and has a seal which rests tightly on a valve seat in the closed position, with at least one water intake line, with a valve assembly for letting in drinking water present in the water intake line, with a water discharge line for discharging the drinking water let in by the valve assembly, and with a controller which generates a control signal for actuating the valve assembly as a function of a sensor signal and/or when a predefined time interval has been exceeded.

A system that monitors toilets for leaks using in-toilet monitors with pressure sensors that are placed underwater in toilet tanks. Monitors can be dropped into tanks without additional wiring or installation; they may be battery powered and may transmit data wirelessly. Data may be analyzed by a server that detects leaks or other malfunctions. Pressure data may be filtered to remove the effect of barometric pressure, to measure the height of water in the tank. The system may learn the flush pressure change pattern for each toilet; pressure changes that do not match this pattern may indicate problems such as leaks. Data may indicate the type of leak, such as an open flapper or a leaking valve. Toilet monitors may measure temperature, and the system may generate alerts when freezing appears imminent. The system may keep flush counts for each toilet to support maintenance and water consumption measurement.

The water-dispensing system with toilet comprises a water generation system and a toilet. The toilet further comprises a water storage tank and an external power source. The water generation system and the water storage tank of the toilet are fluidically connected. The water generation system electrically connects to the external power source. The water-dispensing system with toilet is powered using electrical energy provided by an external power source.

A device for generating a controlled flow event to regulate a hydraulic condition of a piping system of a building is an electrically-powered fluid pump or fluid valve, having a fluid inlet and fluid outlet. The fluid inlet is configured to be in fluidic communication with a tank of a toilet or is supplied water from the piping system of the building. The fluid outlet is in fluidic communication with either: i) a bowl of the toilet; ii) an overflow tube of the toilet tank; or iii) the tank of the toilet; iv) or a drain. An electronic controller controls the operation of the device and is configured to repeatedly turn on and off the electrically-powered fluid pump for a predetermined elapsed time when the hydraulic condition is identified. The hydraulic condition may be a potential freezing condition or an overly high pressure of the piping system of the building.

Systems, methods, and devices relating to urinal, in some examples having a movable portion able to pivot from a generally closed to a generally open position. The urinal may have a drain line engaged with a proximal end of the funnel for conveying urine and rinse water into a sewer line or a toilet bowl and a rinse line coupled with a water supply for rinsing urine therein. The urinal may be movable with the assistance of one or more sensors that may automatically signal other electrical or mechanical components to move one or more portions of the urinal, and may be include elements that seal portions of the urinal when not in use or during cleaning to reduce gas or liquid escaping from the urinal system.

A WC cistern (1) with a wall (2) which forms a substantially cuboidal water tank (3). An intake (5) with which the water tank (3) can be filled is guided through the wall (2). A shutoff valve (7) is arranged in the intake (5), the shutoff valve interacting with a switch-off device (8) which triggers the shutoff valve (7) when a switch-off level (14) in the water tank (3) is reached. An injector (15) is arranged in the water tank (3) in a construction space (13) above the switch-off level (14). The outflow-side outlet (16) of the injector (15) is led out of the water tank (3).

A joint connects to a hot water source, a toilet tank of a toilet, and a hot water outlet. A set of pipes connecting the hot water source and the joint may be referred to herein as “main hot water pipes.” Water exiting the hot water source into the main hot water pipes is above a desired water temperature. As time passes, however, water that rests in the main hot water pipes may fall below the desired water temperature. Rather than wasting all of the cooled water resting in the main hot water pipes in order to use hot water at the hot water outlet, at least a portion of the cooled water may be used to refill the toilet tank. Therefore less cooled water exits the hot water outlet before fresh water reaches the hot water outlet.

A system for monitoring flush valves includes a plurality of flush valves arranged in at least one restroom, each flush valve including a communication device configured to transmit flush valve data, and at least one controller arranged in a first flush valve and in communication with each other flush valve. The at least one controller is configured to determine a static pressure within the first flush valve, detect a second pressure within the first flush valve, determine that the second pressure is less than the static pressure, in response to determining that the second pressure is less than the static pressure, compare the second pressure with at least one other pressure associated with at least one other flush valve, and determine that the first flush valve is in need of servicing or replacement based on comparing the second pressure with the at least one other pressure.
