An example water center appliance configured to incorporate various features associated with a sink is provided. An example water center appliance includes a top section and a bottom section. In one example embodiment, the top section includes a sink basin, a faucet, a water filter assembly, a water inlet connection, and an electricity connection. In one example embodiment, the bottom section includes a first sliding drawer, and a second sliding drawer, wherein the first sliding drawer and the second sliding drawer are shaped to accommodate one or more components of the top section.

The invention relates to a process and a device for enriching water, in particular drinking water, with magnesium ions. In order to enable enrichment of water with magnesium ions in exchange for calcium ions and/or heavy metal ions during treatment of water, and in particular of drinking water, it is proposed according to the invention to pass the water through an ion exchanger which contains a weakly acidic ion exchange material, wherein at least a part of its ion exchange capacity is loaded with magnesium ions.

A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter medium is positioned within the filter chamber, each end of the filter medium being enclosed by an endcap formed from a resilient material, such as molded silicone or a thermoplastic elastomer. The endcaps slide on the ends of the filter media with no need for adhesive and form a fluid seal with both the filter media and the filter housing once installed. One or more fluid bypass channels may be defined by the filter housing or in the endcaps to allow water to flow as desired within the filter chamber. The resulting filter requires fewer components and less assembly time while improving filtration performance and reliability.

A performance indication device for a filter is provided. The performance indication device includes a water metering device to convert the energy of water flowing through the filter into mechanical rotation of a drive gear. A gear reduction assembly operably couples the drive gear to a valve gear and reduces the rotational speed of the valve gear relative to the drive gear. A flow controlling device is operably coupled to the valve gear and is configured to reduce or terminate the flow of water through the performance indication device and the filter when a target flow capacity is reached. The performance indication device thus provides an accurate indication to the user as to when the filter capacity has been expended without the need for a complex control system or communication link or any modification of the appliance in which the filter is installed.

The present disclosure relates to liquid dispensing arrangements, and particularly to arrangements for distribution of a dispensed liquid.

A water purification apparatus includes a water intake configured to receive water to the water purification apparatus, a filter part including a plurality of filters configured to filter the water and generate purified water, a water outlet including a plurality of water outlet ports configured to discharge the purified water, and one or more pipes that define a water purification path configured to guide the water from the water intake through at least one of the plurality of filters to thereby provide the purified water to at least one of the plurality of water outlet ports.

A water filter cartridge is provided for gravity-feed water filtration applications, and includes a granular filter media made from a mixture of titanium dioxide particles interspersed with granular activated charcoal. The granular filter media is placed in a filter housing having an upper inlet opening and a lower outlet opening. A seal may be disposed around an outer periphery of the housing at its upper region, and may include a flange region that flexes upwardly upon insertion of the sidewall into a filter cartridge opening.

A water filter cartridge having an ultraviolet sterilizing function and a water purifier are provided. The water filter cartridge includes a housing, a filtering component, a plurality of flow channels, and an ultraviolet module. The housing has an upper chamber and a lower chamber in fluid communication with the upper chamber. The filtering component is disposed in the upper chamber. The flow channels are arranged in the lower chamber and stacked in a multi-layered arrangement. The ultraviolet module includes an ultraviolet light emitting element disposed in the lower chamber.

A water treatment pitcher includes a portable container, with a cover to and a filling inlet, and a spout for dispensing filtered water. The pitcher has an upper water basin inside the portable container for receiving water, having a filter seat for a filter. The water basin allows the filtered water to drip into and be collected in a space of the container that is lower with respect to the filter when the container is upright; and an ultraviolet (UV) generator configured to radiate UV radiation from a UV emitter on the water collected in the space and to radiate UV radiation from the UV emitter onto the filtered water as it drips from an outlet of the upper water basin to the space of the container that is lower with respect to the filter.

A water purifier includes a water purification unit, and an ice making unit. The water purification unit includes: a water filter for filtering introduced raw water to provide the purified water and unfiltered living water; a purified water tank including a first storage for storing unfiltered water, a second storage for storing the purified water discharged from the water filter, and a separation membrane formed of an impermeable material which independently partitions the first storage and the second storage and has elasticity, wherein the second storage shrinks when the first storage expands, and the first storage shrinks when the second storage expands; a flow channel connecting the water filter, the purified water tank, and the ice making unit to provide a passage through which the raw water, the living water, and the purified water flow; and a valve unit including a plurality of valve modules.
