Water supply throughway for a urinal

A bathroom flusher includes a flusher body, a valve assembly, an electronic control system, and a flusher cover. The flusher body includes an inlet and an outlet, and is designed to accommodate the valve assembly that controls water flow between the inlet and the outlet. The valve assembly includes a valve member movable with respect to a valve seat providing a sealing action based on applied pressure on the valve assembly. The bathroom flusher also includes an external cover designed for enclosing an electronic control module comprising a battery, a sensor, and an actuator for controlling operation of the flush valve, wherein the external cover includes at least two cover parts separately removable, and wherein the external cover is attachable with respect to the valve body in a manner also allowing removable attachment of the control module.

Enclosures for automatic bathroom flushers

An automatic bathroom flusher includes a flusher body, a valve assembly, an electronic control system, and a flusher cover. The flusher body includes an inlet and an outlet, and is designed to accommodate the valve assembly that controls water flow between the inlet and the outlet. The valve assembly includes a valve member movable with respect to a valve seat providing a sealing action. The bathroom flusher may include a user sensor, and one or more photovoltaic cells for supplying electrical power to the electronic control system. The bathroom flusher enables two or multiple flush volumes in automatic or manual modes, depending on a user action. The bathroom flusher may include a user interface including a button and visible LEDs.

Enclosure for automatic bathroom flusher

A filtering seal for a solenoid valve has an annular base member which defines an axial first retainer surface and a radial sealing surface. Legs extend from the base member. An annular screen support member is attached to the legs and has an axial second retainer surface. The first and second retainer surfaces are on outside diameters of the base member and screen support member. A cylindrical filter screen has one end mounted on the base member and the other end mounted on the screen support member, in engagement with the retainer surfaces. The base member may have bosses protruding from an end face to form a rotary seal suitable for engagement with a swivel connector. The radial sealing surface of the base member is located outwardly of the filter screen where the radial sealing surface can be compressed without affecting the filter screen.

A network of wirelessly connected sanitary appliances, their associated triggering devices and a remotely located network node is disclosed. The remotely located network node permits the monitoring and gathering of information concerning the appliances and their associated triggering devices. The network node can be connected to a LAN and/or the internet allowing the node to communicate with responsible parties. In addition, a control board having a central processing unit is wirelessly connected as an intermediary between the appliances and triggering devices and the network node. Communication between the appliances and their triggering devices uses low frequency RF signals. Communication to the remotely located network node uses high frequency RF signals.

The invention provides a radio frequency (RF) valve control system that replaces mechanical systems that physically links a button or a handle to a flush valve or hard wired electronic control systems that physically links a sensor/electronic switch to a valve actuator within a plumbing installation. The new system is characterized by two modules, a user interface module (UIM) for locating at or adjacent a plumbing fixture (such as a water closet or urinal), and a valve interface module (VIM) operatively connected to a flush valve actuator or a valve in the water supply line of the plumbing fixture. The UIM generally has the function of providing an RF valve control signal to the VIM and the VIM has the functions of receiving, analysing, and responding to the RF valve control signal and sending a signal to the valve actuator to initiate a flush cycle or initiating a valve control process to control a valve within the water supply line to start or stop water flow to the fixture. The system may be deployed as a single UIM/VIM pair or as multiple UIM/VIM pairs within a multi-fixture installation. In each case, each UIM/VIM pair communicates with its respective UIM or VIM in both a learning and active mode.
