Proposed is a non-electric water purifier in which a flow path provided between a water-purifying filter and a water outlet cock is replaced in order to minimize contamination of purified drinking water. The non-electric water purifier includes a main body having a door formed on one side thereof so as to open and close the main body and having and having a receiving space part defined therein, a connector which is coupled replaceably and rotatably to one side of the main body and incudes a raw water passage connected to a raw water inlet and a purified water passage through which purified water flows, at least one filter housing being received in the receiving space part, with a discharge outlet of the filter housing being coupled detachably to the connector, and the water outlet cock which is connected to a discharge opening of the connector and discharges purified water.

A water purifier includes a filter head, a flow channel control module, and a filter element. The flow channel control module includes a waterway board and a flow manifold. The waterway board is provided with a water flow channel. The flow manifold is provided with a first passage and a second passage. When the flow manifold is driven by the filter element and rotated relative to the waterway board to a first position where the first passage is connected to the water flow channel, the flow channel control module is switched to a first flow channel waterway mode (or filter mode). When the flow manifold is driven by the filter element and rotated to a second position where the second passage is connected to the water flow channel, the flow channel control module is switched to a second flow channel waterway mode (or replacement mode).

Provided are a water purifying apparatus and a refrigerator including the same. The water purifying apparatus includes a filter configured to purify incoming water and discharge the purified water, a head in which the filter is detachably coupled and a water inlet portion and a water outlet portion are formed, and a shaft provided inside the head and rotatably mounted between the water inlet portion and the water outlet portion, the shaft being provided with a bypass flow path directly connecting the water inlet portion and the water outlet portion and a filtering flow path connected so that water flowing in through the water inlet portion is discharged to the water outlet portion via the filter.

A filter assembly and method of filtering wastewater from a washing machine. The filter has a framework for supporting a first filter stage and a second filter stage, a connection on a top of the filter assembly for connecting to a wastewater stream, a diffuser positioned to extend into the first filter stage and configured to rotate about a vertical axis of installation within the first filter stage, and a second filter stage below the first filter stage and configured to receive overflow from the first filter stage. The filter assembly does not include a motor or motorized parts and wherein the diffuser is rotatable by way of the force of the wastewater stream fed into the first filter stage to diffuse the wastewater stream and to spray the wastewater onto and through the filter media allowing the filter media to catch debris within the first filter stage.

A water filter cartridge is provided. The water filter cartridge includes a filter housing enclosing a filtration material therein. A port shield is connected at one end of the filter housing and disposed between the filter housing and a connector part adapted for securing the water filter cartridge to a refrigerator filter part. The port shield is provided for at least partially covering a water inlet port and a water outlet port extending at least between the connector part through the port shield and at least partially through the filter housing. The port shield at least partially encloses the water inlet and/or water outlet port therebetween and also separates the filtration material and unfiltered water within the filter housing from the portions of the water inlet and outlet port within the port shield.

Provided is a UV lamp socket assembly for quickly, easily and safely drawing out a UV lamp without stopping operation of a UV reactor. The UV lamp socket assembly includes a lamp socket part allowing a UV lamp to be fitted thereto, and having a latch formed in a side surface to pivot around; a lamp socket nut part allowing the UV lamp to be inserted therethrough, having an annular latching groove formed in a side surface and provided for attaching and detaching the latch, and allowing a portion of the lamp socket part to be inserted while the latch is latched into the latching groove; and a lamp socket holder part to be fixed to a frame of the UV reactor using a fastening part and to be fastened with the lamp socket nut part to support the lamp socket part.

A small processor produces potable water from contaminated water. Its components mount in a hermetically sealed housing, which include a boiler-condenser assembly and a compressor unit. Contaminated water is injected onto one or more aluminum shells' inside surface of the boiler-condenser assembly. Shell rotation enhances boiling heat transfer by causing the water to form thin films on the shells' inside surface. Shell rotation also enhances condensing heat transfer by assisting in removing the purified condensate from the shells' outer surface. The change of phase heat of condensation energy from vapor to liquid transfers through the shells to the boilers to cause boiling. Vapor boiled inside the boiler chambers flows toward the compressor, which raises the vapor's pressure and temperature to drive the process. Shell rotation causes centrifugal force that holds and directs concentrated un-boiled remaining water on the shells' inside walls towards the output pumps. Wipers mounted adjacent each shell's boiler surface smooth contaminated water. Wipers adjacent the condenser surfaces help remove condensate from that surface to present a clean condenser for improved condensation.

A water purifier capable of stably discharging residual water from an extraction unit is disclosed. The water purifier (100) comprises: a filter unit (110) having a reverse osmosis membrane filter (113) for filtering incoming water; an extraction unit (160) for providing purified water filtered by the filter unit (110) to a user; and a residual water drainage unit (150) configured to drain, through the reverse osmosis membrane filter (113), residual water remaining in the extraction unit (160), by using an osmotic phenomenon of the reverse osmosis membrane filter (113) after completion of the extraction through the extraction unit (160).

Provided is a filter element comprising a filter element body having a cavity, a water inlet and a water outlet, an end cap, and a perforated partition, and the perforated partition is configured to divide the filter element body into a first chamber filled with an adsorption filter material and a second chamber filled with an ion exchange filter materials. In the present disclosure, the filter element is divided into two stages, and the primary filter material and the softening filter material are filled separately, and functions of both filtration and descaling are realized, addressing the issues blocking of water and reduced water flow in the coffee machine using a PP/PE filter element. Meanwhile, reduction in water flow caused by the mixing of the filter materials and the caking of the filter material is also solved.

The present invention relates to a multipurpose tool that is configured to collect seaweed and other debris from the edges of a body of water and from shorelines. The tool has an elongated handle having an ergonomic grip, a head portion, a plurality of tines extending from the head portion, and a removably attached net-like filter. Each tine has an elongated length with a downwardly extending distal portion and is supported by a curved brace, wherein the curved brace extends laterally across the tines for providing mechanical support to the tines. The tines are oriented in a tapered manner having less spacing between the tines near the head portion and more spacing between the tines at the distal end which allows the width of the tines to be larger at the distal end than near the head portion.
