An ice making assembly within an appliance with a housing having an inlet and an outlet, and a lower portion and an upper portion. The assembly includes a rotatable shroud within the housing with a first slot in air communication with the inlet, and a second slot in air communication with the outlet. A thermoelectric device with a top side and a bottom side, and having a heat sink on the bottom side between the first slot and the second slot. An ice tray disposed above and thermally connected with the top side, a barrier wall within the housing and in contact with the shroud between the lower portion and the upper portion.

An ice making assembly includes an ice mold including two or more separable portions that collectively define one or more mold cavities. Each of the mold portions define a plurality of recessed passages that at least partially surround the mold cavity and are configured to receive evaporator conduit of a sealed refrigeration to cool the ice mold and facilitate formation of an ice billet.

Provided is an ice maker including an upper tray and a lower tray made of an elastic material, wherein a plurality of upper chambers defined in the upper tray and a plurality of lower chambers defined in the lower tray are in contact with each other to define a plurality of spherical ice chambers, respectively, each ejector-receiving opening opened to each of the plurality of upper chambers, each opening-defining wall extending upward along a circumference of each ejector-receiving opening, an upper ejector configured to pass through the ejector-defining wall and vertically move to remove each ice from each ice chamber, and a driver for pivoting the lower tray to open and close the upper tray and the lower tray, wherein the upper tray includes a horizontal extension forming a top face of the upper tray, wherein the upper chamber is positioned below the horizontal extension such that the opening-defining wall is formed at a vertical level equal to or lower than a vertical level of the opening-defining wall.

An ice maker for a refrigeration appliance, the ice maker including an ice maker frame and an ice tray housed within the ice maker frame and configured to form ice pieces therein. An air handler is disposed adjacent the ice maker frame and an ice maker fan is disposed within the air handler and is configured to direct cooled airflow out of the air handler and into the ice maker frame. A controller is configured to operatively control the ice maker during an ice making cycle. The ice maker is operable in a first mode and a second mode. When the ice maker is operated in the second mode, the ice maker fan is cycled on and off during predetermined time intervals in order to produce clear ice pieces.

Provided is an ice-maker including an upper tray made of an elastic material, and having a plurality of upper chambers defined therein, a lower tray made of an elastic material, and having a plurality of lower chambers defined therein in contact with the plurality of upper chambers to define a plurality of spherical ice chambers, respectively, each ejector-receiving opening defined in the upper tray and opened to each of the plurality of upper chambers, an upper ejector disposed above the upper tray, wherein the upper ejector is configured to pass through the ejector-receiving opening and remove each ice from each ice chamber, a water supply for supplying water for ice-making through the ejector-receiving opening, and a driver for pivoting the lower tray.

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.

A manufacturing apparatus for a solidified matter of an ultra-fine bubble (UFB)-containing liquid includes: a UFB generating unit that generates the UFB-containing liquid; and a cooling unit that generates the solidified matter of the UFB-containing liquid by cooling the UFB-containing liquid. The cooling unit cools the ultra-fine bubble-containing liquid such that a first solidified portion and a second solidified portion at a lower ultra-fine bubble concentration than that of the first solidified portion are formed in the solidified matter.
