Abstract: An electrolysis cell and housing provides for simple, toolless cell installation and removal of the electrolysis cell. The electrolysis cell includes an anode and a cathode and requires periodic removal of the electrolysis cell from the housing for cleaning or replacement due to accumulation of deposits on the anode and the cathode. The electrolysis cell includes three push-in fluid connectors and two push-in electrical connections. A filter may be included serially between a water inlet and the electrolysis cell and may include two push-in fluid connectors. A housing rear cover may hold the electrolysis cell and filter in place in the housing and may be removed and reattached to access the electrolysis cell without tools.

Abstract: A customizable multi-stage fluid treatment assembly typically includes a connector, a plurality of cartridges, and a cap. The plurality of cartridges have a treatment medium spaced within an interior volume of the individual cartridges, between the ends thereof. The ends of the plurality of cartridges are configured to receive a fluid, bring the fluid into operative contact with the treatment medium, and dispense the fluid from the opposing end of the cartridge. The connector is coupled with one end of the plurality of cartridges and has an inlet and an outlet for receiving and dispensing the fluid to and from an appliance. The cap is coupled with the other end of the plurality of cartridges, enclosing the fluid treatment assembly, which is configured to be received in a cavity of an appliance. The cartridges of the plurality of cartridges may be individually replaced with cartridges to meet customized needs.

Abstract: In one example, a pitcher is provided that includes a chassis in which an untreated water reservoir is received. The untreated water reservoir has a candle that defines a receptacle with a fluid inlet and a fluid outlet, where the fluid outlet is arranged for fluid communication with the treated water reservoir, and the receptacle is configured to receive a filter cartridge. The candle also includes a filter seat that cooperates with the filter cartridge to form a substantially fluid-tight seal when the filter cartridge is positioned in a sealing range defined by the candle. The pitcher also includes a structural element that is connected to a portion of the pitcher and has a protruding portion that is located near the filter cartridge when the filter cartridge resides in the sealing range.

Abstract: An integrated waterway assembly of a reverse osmosis (RO) water filtration device includes a main body, a shut off valve, a mounting shelf, a top cover, a bottom cover and a fixing ring. Water to be filtered sequentially goes through a water inlet, a shut off valve, a RO cartridge joint and a check valve, and a filtered water outlet on the main body to get the water filtered. The RO cartridge joint on a bottom portion of the main body is connected with a RO cartridge, and water enters the RO cartridge and further flows through the RO cartridge joint to get the water filtered. Given the foregoing structure, the water filtration device is structurally compact and integrated and has less water leakage.
