Vacuum toilet flush valves. The disclosure uses a precise positioning of a magnet with respect to a flush valve plate in order to identify absolute alignment accurately.

A powerless automatic flushing device is proposed. The device controls flushing of feces and time to dispose of toilet paper with feces while suctioning air from outside through a feces toilet paper time adjustment part and a flushing adjustment part when a toilet user defecates and leaves a toilet seat, and respectively controls the flushing of urine and time to dispose of toilet paper with urine while rapidly suctioning the air from the outside through each of a feces toilet paper time adjustment part, a flushing adjustment part, and a urine toilet paper time adjustment part when the toilet user urinates and leaves the toilet seat, thereby preventing the toilet user from wasting the water by unnecessarily pressing a lever, and a tension load spring compresses in conjunction with descending motion of the toilet seat and retains a tension load force capable of pulling a flushing wire.

An unpowered automatic flushing module for a flush valve having an integrated flushing opening/closing portion is proposed. The module controls time to dispose of toilet paper with feces and flushing of the feces while suctioning air from outside through a toilet paper time adjustment part when a toilet user defecates and leaves a toilet seat, and controls time to dispose of the toilet paper with urine and flushing of the urine so as to flush an amount of water for urination while rapidly suctioning the air from the outside through the toilet paper time adjustment part and a urine flushing adjustment part when the toilet user urinates and leaves the toilet seat, thereby preventing the toilet user from wasting the water by unnecessarily pressing a lever. In addition, the flushing opening/closing portion is integrated into a module of a detection switch instead of fixing to the toilet seat separately.

A water control system for a tankless toilet includes a first flush control operating a first control valve, a second control valve, and a first water supply valve. The first control valve is moved by operation of the first flush control. The second control valve and the first water supply valve move by operation of the first control valve. When the first control valve is closed pressurized water is applied to the second control valve and the first water supply valve to maintain them closed. When the first control valve is open the water pressure applied to the second control valve and the first water supply valve is reduced causing them to open. When the first water supply valve is closed pressurized water is prevented from being delivered to a toilet bowl and when open pressurized water is delivered to a bottom jet of the toilet bowl.

A toilet configuration that is connectable to a sewer drainage pipe is provided. The toilet configuration includes a water storage tank, a ceramic toilet body including a toilet bowl, and a water supply plenum operable to receive water from the water storage tank and channel the water to the toilet bowl. The toilet configuration further includes a primary drain operable to fluidly connect the waste receiving basin and the sewer drainage pipe and at least one footrest formed unitarily with an outer surface of the ceramic toilet body. The footrest is operable to aid a user in elevating at least one knee while the user is seated upon the toilet configuration.

A device adapted for installation onto a toilet overflow pipe to indicate a leaking condition of a toilet flush valve. The device having a stem portion with a diameter configured for receipt within an interior diameter of a toilet overflow tube. The device including a housing forming a reservoir for collection of water prior to entering the overflow tube. The reservoir including a cavity for the placement of a water soluble pigment, wherein the pigment is dissolved within water in the housing and into the overflow tube. An alternate embodiment of the device, includes a stay member configured to support a ball float member in an off condition.

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.

Various embodiments for conserving fluid based on the position of a toilet seat are presented. One example embodiment includes a toilet flushing system having a fluid regulation component and a position detector. The fluid regulation component is configured to regulate an amount of fluid used to flush a toilet during a flush cycle. The position detector is configured to detect whether the toilet seat is in a raised position or a lowered position. The position detector is coupled to the fluid regulation component to communicate whether the toilet seat is in the raised position or the lowered position. The fluid regulation component is further configured to regulate the amount of fluid used during the flush cycle based at least in part on whether the toilet seat is in the raised position or the lowered position.

A toilet installed in a bathroom includes a toilet bowl and a tank coupled to the toilet bowl. The tank can contain fluid for the toilet bowl. A rear surface of the tank is flush against a wall of the bathroom such that there is no gap between the tank and the wall and a bottom surface of the tank is flush against a floor of the bathroom such that there is no gap between the tank and the floor. The tank extends longitudinally above and below the toilet bowl and laterally outward past the toilet bowl such that a first side surface and a second side surface of the tank define outermost side peripheries of the toilet.
