The housing cap includes an upper portion, a lower portion, and a channel formed through the upper portion and the lower portion. The water filter also includes an interface adapter accommodated in the channel, wherein the interface adapter includes a side wall vertically extending from an upper surface of the interface adapter and partially around a perimeter of the upper surface, and a projection vertically extending from the upper surface, wherein the projection is integrally formed with the upper surface and a portion of the side wall.

A water delivery control system operates to selectively deliver water from a water source to water use devices. The system includes a master controller that wirelessly communicates messages with a plurality of slave controllers. The system includes a valve slave controller associated with a water control valve and a motor that is operative to selectively move at least one valve element of the valve. A water meter is operative to measure water flow that corresponds to flow through the valve. The master controller is operable to cause the valve slave controller to enable or prevent flow through the valve responsive at least in part to water flow data. The controller is operative to determine a water use condition responsive to a water usage pattern, and to cause at least one message to be sent to a portable user device responsive to the determined water use condition. The user interface slave controller is associated with a user interface.

An installation structure of an external filter case for a refrigerator is provided. The filter case may include a main body that provides an inner space in which an internal line may be installed and water filters may be installed, and a cover that covers the inner space of the main body and is detachably coupled with the main body. The main body may have an open front side and may include bosses that protrude from its bottom face. The cover may include insertion holes into which the bosses may be inserted. A lower portion of the main body may be coupled with a lower portion of the cover. Magnets may be installed in upper portions of the main body and the cover, respectively, such that the main body and the cover may be coupled with each other by a magnetic force.

A fluid waste filtration system includes a housing configured to be coupled between and in fluid communication with a sink and a primary grease trap. The housing defines a chamber and includes a fluid inlet, a fluid outlet, and a grease outlet each in fluid communication with the chamber. The grease outlet is defined in a plane at or above a plane of the fluid outlet. A wall is disposed in the housing and divides the chamber into a first chamber and a second chamber. The wall is configured to direct a fluid that flows into the first chamber through the fluid inlet toward the grease outlet.

The polarization and turbulent water ionizer intended for white and sanitary conveniences comprising a hollow body with a system of through-flow openings for inlet and outlet of water fitted with systems of electrodes arranged inside in an alternating manner, made of differently conductive materials and stabilized within spacers is further resolved in a manner where the cylindrical or flat electrodes (1) of the anode and of the electrodes (2) of the cathode have turbulent openings (3) and/or deflected turbulent fans (4), where the hollow body (5) is fitted with a shield (6) protecting against electromagnetic field. In one embodiment the axes of the cylindrical electrodes (1) of the anode and of the electrodes (2) of the cathode are arranged inside the hollow body (5) and oriented perpendicularly to the through-flow openings (7). In the other case, the axes of the flat electrodes (1) of the anode and of the electrodes (2) of the cathode are arranged inside the hollow body (5) and oriented axially with reference to the through-flow openings (7). The shield (6) protecting against electromagnetic field applied on the inner side of the hollow body (5) refers to a metallic grid/gauze and/or a metallic plate.

An antibacterial cleaning machine with wet filter includes a container body inside which are disposed at least one motor group for aspirating flows of air and debris from outside; at least one first tank for collecting the debris which contains a first volume of filtering liquid which is arranged along the passage path between the inlet and outlet; at least one internal path of the flows of air and debris that includes an inlet, an outlet, conveying means that have an inlet immersed in the filtering liquid. The tank includes at least one sanitizing element made of silver and/or silver alloy which is positioned immersed in the volume of filtering liquid.

A filter assembly and a method of operating the same to detect water leaks are provided. The filter assembly includes a filter housing for receiving a filter cartridge and at least partially defining a drain trough positioned below the filter cartridge for collecting leaked water. A light source is positioned proximate the drain trough for directing light through the drain trough and a light sensor is positioned proximate the drain trough for sensing the light directed through the drain trough. A controller uses the light sensor to monitor the light generated by the light source and determines that a leak exists when an intensity of sensed light is reduced by the leaked water.

The invention provides a device with a steam function, wherein the device includes a water supply opening, a scale inhibitor dosing element, a flow control device, a heating unit, a scale collector element, and a water processing unit. Further, the flow control device provides a fluid including water to flow from the water supply opening via the heating unit to the water processing unit; the scale inhibitor dosing element provides a scale inhibitor to the water at a location in the heating unit and/or upstream of the heating unit; the heating unit includes heating the water in a heating mode and for converting the water into steam in a steam formation mode; and the scale collector element is arranged downstream of the heating unit and upstream of a flow restriction, wherein the scale collector element includes collecting scale particles from the fluid flowing through the scale collector element.

A reactor that operates with ultraviolet light emitting diodes (UV-LEDs) to attain UV photoreactions or UV photo-initiated reaction in a fluid flow for various applications, including water purification. The UV-LED reactor is comprised of a conduit means for passing fluid flow, an ultraviolet light emitting diode (UV-LED), and a radiation-focusing element to focus the UV-LED radiation to the fluid in the longitudinal direction of the conduit. The UV-LED reactor may include photocatalysts or chemical oxidants, which are activated by UV emitted by UV-LEDs for photocatalytic and photo-initiated reactions.
