A fluid device includes: a first flow path that extends along a first axis and through which a fluid flows in a positive side of the first axis; a first ultrasonic element configured to generate a first standing wave along a second axis orthogonal to the first axis in the first flow path; and a second flow path connected to the first flow path such that the fluid flows therethrough and extending along a third axis intersecting a plane including the first axis and the second axis. A first connection port for connecting the first flow path and the second flow path is formed corresponding to a position of either an antinode of the first standing wave or a node of a first standing wave.

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 disposable filter for a sink including a substantially inverted disposed conical filter having a rounded conical apex and a continuous horizontally disposed circular bottom rim. A circular top rim is continuously disposed on a top surface of the bottom rim of the filter. A concave-shaped indentation is continuously disposed through each of an exterior edge of the bottom rim and an outer surface of the top rim. A plurality of tabs is attached to the outer surface of the top rim. An adhesive layer is disposed on a bottom surface of the bottom rim of the filter. The filter is removably disposed atop an exterior surface of a sink, with an exterior edge of the indentation disposed around an exterior surface of a base of a faucet.

A water purifying apparatus including a head having a water inlet portion and a water outlet portion; a shaft provided in the head and rotatably mounted between the water inlet portion and the water outlet portion; a bypass flow path passing through a circumference of the shaft, and communicating the water inlet portion with the water outlet portion according to rotation of the shaft; a filter detachably mounted to the head, and having a filter inserting portion in which the shaft is inserted when being mounted on the head; and a filtering flow path in which an inlet port and an outlet port are formed on the circumference of the shaft in a direction intersecting the bypass flow path, and communicated between the filter, the water inlet portion and the water outlet portion with each other according to the rotation of the shaft.

A water ozonation system (18) that receives source water (16) from a water source (14) and converts it to ozonated water (20) for use in a washing machine (12) includes a system body (30), an ozone generator (38), a sensor assembly (21), and a controller (46). The system body (30) receives the source water (16) from the water source (14). The ozone generator (38) is configured to generate ozone. The ozone generator (38) is coupled the system body (30). The sensor assembly (21) is also coupled to the system body (30). The sensor assembly (21) is configured to sense at least one ambient environmental condition and generate at least one electronic data signal based on the sensed at least one ambient environmental condition. The controller (46) receives the at least one electronic data signal from the sensor assembly (21) and regulates a level of ozone that is generated by the ozone generator (38) based at least in part on the at least one electronic data signal.

A filter cartridge for a domestic cooling appliance includes a beaker-shaped housing which is provided at an open end with a coupling for securing to a filter head, and a particle filter insert which is received in the housing. The particle filter insert is guided movably along an axis of the housing between an abutment position, in which it is embedded completely in the housing, and a position in which it at least partially protrudes from the housing. A domestic refrigeration appliance having the filter cartridge is also provided.

The present disclosure relates to a refrigerator in which an internal volume is maximized and efficiency of a hydrogen water module is maximized. The present disclosure relates to a refrigerator with improved ease of use and improved serviceability by replacing a hydrogen water module without using a tool. The present disclosure relates to a refrigerator that can prevent hydrogen from remaining on an upper side inside a hydrogen water module and can also prevent an amount of hydrogen dissolved in hydrogen water from being reduced.

An upright water filtration vacuum containing a antimicrobial particulate for anti-bacterial and anti-fungal properties. The water filtration vacuum device draws in the air, forcing it in to the water and mixing it with, e.g., nano-silver, returning clean, fresh air in to the home environment.

Keyed fluid-handling devices comprise a fluid-handling device such as a filter, a bypass, or an adapter and an optical key. The optical keys are amenable to all types of filter component and can be readily retrofitted to existing designs. The optical keys may be formed from a variety of materials and combination of phases. That is, optical keys may comprise one or more solid materials, or perhaps may result from a combination of: solid materials, such as in transparent or semi-transparent polymers or glass; liquid fluids, such as water; and gaseous gaps such as an air gap. Optical keys may be light conduits or light guides. Filter manifolds comprise optical locks to ensure compatibility of the filter components.

Non-plumbed appliances and filters are provided. A filter includes a body which includes a sidewall extending along a longitudinal axis between a first end wall and a second end wall, the body defining a body interior. The filter further includes an inlet defined in the body, and a nozzle protruding from the second end wall along the longitudinal axis and defining an outlet, the nozzle offset along an outer surface of the second end wall from a centroid of the outer surface. The filter further includes a tab configured on the body, and a filter medium disposed within the body interior, the filter medium operable to remove contaminants from water flowing through the filter medium.
