Various examples are provided for smart water filter systems. In one example, a smart water filter system includes a solenoid valve (or other electrically operated valve) in a water supply line of a faucet, and a filter bank coupled to the water supply line. Activation of the valve can stop the flow of unfiltered water through the faucet while allowing the flow of filtered water through the faucet. In another example, a smart water filter system includes a three-port solenoid (or electrically operated) valve coupled to a faucet, and a filter bank coupled to the water supply line and to a second inlet port of the three-port solenoid valve. Activation of the three-port valve can stop the flow of unfiltered water through the faucet while allowing the flow of filtered water through the faucet.

A dual-purpose household water purifier includes a main unit and an expansion unit which can be detachably connected. When the main unit is connected with the expansion unit, a booster pump can pressurize tap water entering a filter assembly. In the dual-purpose household water purifier, the main unit can be used as a non-electric drive water purifier. After the tap water enters the filter assembly and is filtered. The purified water flows into the purified water chamber of the pressure bucket, and the user takes the purified water. It is further provided an expansion unit. When the main unit is connected to the expansion unit, the booster pump can pressurize the pipeline, reducing application environmental restrictions on the water purifier. Through arrangement of the expansion unit, the water purifier can be operated in two operation modes of non-electric drive mode and electric drive mode.

A system includes an assembly with a filter, a pipe and a connector. The filter includes a housing and a cartridge situated within the housing. The pipe feeds water to a water dispersing arrangement via an inlet pipe channel extending therethrough from upstream to downstream ends. The connector includes a spout having a spout outlet channel couplable to an upstream portion of the inlet pipe channel and a spout inlet channel couplable to a downstream portion of the inlet pipe channel. The filter is attachable to the pipe via the connector. When the assembly is in Active configuration, water from the upstream portion passes through the spout outlet channel, the cartridge, the spout inlet channel and into the downstream portion. When the assembly is in Bypass configuration, water from the upstream portion passes into a bypass channel to exit the assembly without passing through the cartridge.

A system includes a filter assembly with a filter and an inlet pipe. The filter includes a connector, a housing couplable to the connector, and a filter cartridge within the housing. The connector includes a spout with inlet/outlet channels. The pipe feeds water to a dispersing arrangement via an inlet pipe channel extending therethrough from upstream to downstream ends. An upstream portion of the inlet pipe channel is coupled to the inlet channel and a downstream portion of the inlet pipe channel is coupled to the outlet channel. The assembly is movable between Active configuration (the inlet/outlet channels are open so that water from the upstream portion passes through the inlet channel into the cartridge and through the outlet channel into the downstream portion) and Bypass configuration (the inlet/outlet channels are closed so that water passes through a bypass channel to exit the assembly without passing through the cartridge).

A double-waterway faucet structure is provided. A faucet body comprises a first water inlet passage, a second water inlet passage, and a first water outlet passage configured to be in communication with the first water inlet passage, and the first water outlet passage is connected to a pull-out head. A control valve is disposed on the faucet body and is configured to control a turning ON and OFF between the first water inlet passage and the first water outlet passage. A rotating bracket is rotatably disposed on the faucet body and comprises a second water outlet passage configured to be in communication with the second water inlet passage, and a solenoid valve is disposed on the second water inlet passage to control a turning ON and OFF of the second water outlet passage.

A water discharge apparatus WD executes a water film formation step of ejecting running water and forming a water-splash suppression water film of the running water on a surface of a sterilization object, before executing a sterilization step of discharging sterilization water from a sterilization water ejection unit 20 toward the sterilization object.

A method for adjusting settings in a water recirculating device is provided. The water recirculating device comprises an outlet configured to output treated water, a water collecting arrangement configured to collect used water, a water treatment arrangement configured to receive used water from the water collecting arrangement and output the treated water, wherein said water treatment arrangement is further configured to hold a replaceable water treatment device, an external water input device configured to input external water to said recirculating device, a circulation pump configured to provide a flow in said water recycling device, and a data processing device configured to control said water recycling device. The method comprises retrieving information associated to said replaceable water treatment device, determining identification data for said replaceable water treatment device by processing said information, retrieving settings data connected to said identification data, and adjusting said water recirculating device according to said settings data.

Various examples are provided for smart water filter systems. In one example, a smart water filter system includes a solenoid valve (or other electrically operated valve) in a water supply line of a faucet, and a filter bank coupled to the water supply line. Activation of the valve can stop the flow of unfiltered water through the faucet while allowing the flow of filtered water through the faucet. In another example, a smart water filter system includes a three-port solenoid (or electrically operated) valve coupled to a faucet, and a filter bank coupled to the water supply line and to a second inlet port of the three-port solenoid valve. Activation of the three-port valve can stop the flow of unfiltered water through the faucet while allowing the flow of filtered water through the faucet.

The present inventive concept relates to a method for recycling water in a water recycling device, the method comprising: receiving used water via a drain; determining a water quality measure of the used water; if the water; quality measure of the water is above a first quality threshold, feeding the used water to a valve arrangement; in the valve arrangement, forming water to be treated by providing external water, the used water or a combination of the external water and the used water; generating treated water by treating the water to be treated using a water treatment arrangement; and feeding the treated water to an outlet. The present inventive concept also relates to a water recycling device.

Kitchen appliances usually include devices such as a water system, a cooker, a kitchen hood (range hood), an oven, a refrigerator, a microwave, a dishwasher and other devices. The devices are mostly operated independent from each other. Unlike those devices the drinkable tap water-based liquid supply system according to the present invention comprises a few devices controlled by an advanced control system according to the invention for providing connectivity and system management. The system is designed to provide comfort, convenience and energy saving. The water-based liquid supply system according to the present invention provides a variety of water-based liquids, dispatched with the desired properties from a countertop faucet.
