A filter cartridge assembly for an ice making appliance having a rectilinear filter cartridge with a plurality of partitions that are positioned within an internal chamber, form multiple sub-chambers, and create a non-linear pathway for the flow of water through the filter cartridge. Filter media positioned in the sub-chambers of the filter cartridge are configured to remove dissolved solids from water travelling through the filter cartridge and used by the appliance to create ice, including clear ice.

A refrigerator appliance includes an ice maker provided within a cabinet of the appliance, the ice maker including a plurality of walls forming a receiving space, a conductive ice mold provided within the receiving space, the conductive ice mold defining an internal cavity and an exterior surface, a primary water supply positioned below the conductive ice mold to direct an ice-building spray of water to the conductive ice mold, a heat exchanger disposed on the conductive ice mold to draw heat therefrom, and a secondary water supply provided adjacent the exterior surface of the conductive ice mold. The secondary water supply dispenses ice-melting water over the exterior surface of the conductive ice mold.

An ice maker comprising a refrigeration system, a water system, and a control system. The control system includes a controller comprising a processor and a water level sensor. The water level sensor is adapted to externally sense a capacitance corresponding to a sump water level. The controller is adapted to control the operation of the refrigeration system and the operation of the water system based upon the sump water level and to detect one or more failure modes of the water system based upon the sump water level.

Disclosed is a transparent ice manufacturing system including a reservoir tank, in which a liquid is stored, a mold having a cavity, in which the liquid supplied from the reservoir tank is filled to form ice, a cooling part that cools one area of the mold to manufacture ice while freezing the liquid from the one area to an opposite area of the mold, and a fluid circulation part provided between the reservoir tank and the mold, and that circulates the liquid between the reservoir tank and the cavity while the liquid is frozen in the cavity.

A batch ice maker can execute a pulsed fill routine in which a control system pulses water from a water supply into the sump until the sump reaches a predefined freeze routine starting level. Pulsing may begin after continuously filling the sump to a fill-approach level. A batch ice maker can execute a differential freeze routine in which the control system circulates water from a sump to an ice formation device until water level decreases by a predefined differential amount from a high control water level based on the water level in the sump at a point in time after the sump was filled to a freeze routine starting level. The high control water level can be set based on water level in the sump when sump water temperature reaches a predefined pre-chill temperature. The predefined pre-chill temperature can be associated with a switchover from sensible cooling to latent cooling.

Provided is a water purifier comprising: a filter unit which has a reverse osmosis membrane filter; a supply valve; an instantaneous heating device which is provided with an inflow port, and an outflow port, and which heats and purified water entering through the inflow port and flowing to the outflow port, so that hot water is discharged through the outflow port; an extraction member; a supply pump; a domestic water drain line; a hot water drain line; a hot water drain valve; and a control unit which controls the opening/closing of respective flow channels of the hot water drain line and the domestic water drain line so that, among a hot water draining process through the hot water drain line, and a domestic water draining process through the domestic water drain line, the hot water draining process is carried out first.

A refrigerator includes a main body defining a storage compartment, a door, an ice making device, a water tank disposed for supplying water into the ice making device, and an ice bin to receive and store ice pieces made in the ice making device. The ice making device includes an ice making tray having ice making chambers configured to be filled with water for making the ice pieces, and an ejector extending from an upper central portion of the ice making tray in a longitudinal direction of the ice making tray to pass through both ends of the ice making tray. The ejector is configured to be maintained in a fixed state during water supply, ice making, and ice separation processes, and the ice making tray is configured to rotate at an angle of about 360° in one direction with respect to the ejector.

An ice maker includes a dry compartment and a wet compartment adjacent to the dry compartment and including: an evaporator case sized to receive an evaporator, the evaporator case including: a plurality of interior panels joined to each other with snap-fit joints, each of the snap-fit joints including a tab and defining a slot, each of a plurality of seams formed between the interior panels defining a foam-tight seal and a water-tight seal; and a plurality of exterior panels, each of the plurality of exterior panels joined to a mating interior panel of the plurality of interior panels with slide joints, wherein the evaporator case is integrally insulated with blown foam insulation positioned between each of the plurality of exterior panels and a corresponding interior panel.

A water storage box and a refrigerator; the water storage box includes a box body and a front panel provided on a front end surface of the box body, and further includes: a locking structure including a locking part and a fitting part, one of the locking part and the fitting part being provided on a rear surface of the front panel, the other of the locking part and the fitting part being provided on the front end surface, and the locking structure being provided near a first side of the front end surface; at least one overturning structure provided between the rear surface and the front end surface, the at least one overturning structure being provided close to a second side of the front end surface, and the first side being opposite to the second side.

An ice maker of a refrigerator includes a tray assembly having an upper tray that defines upper portions of a plurality of ice making chambers. Each of the plurality of ice making chambers is configured to receive water and generate an ice piece. The tray assembly also includes a lower tray that is located vertically below the upper tray, that is configured to rotate relative to the upper tray, and that defines lower portions of the plurality of ice making chambers, wherein at least one of the upper tray or the lower tray comprises a flexible tray made of a flexible material. Additionally, a case is configured to accommodate the flexible tray to restrict a deformation of the flexible tray. A heater that is located between the case and the flexible tray is configured to supply heat to the plurality of ice making chambers through the flexible tray.
