A refrigerator includes a cabinet forming a storage space, a door configured to open or close the storage space, and an ice maker provided in the storage space or the door. The ice maker includes an upper tray including an upper chamber forming an upper portion of an ice chamber, a lower tray including a lower chamber forming a lower portion of the ice chamber, and an upper heater disposed along a circumference of the upper chamber so that at least two heating regions are formed at different positions in a vertical direction in the upper chamber.

An ice maker includes an upper tray that includes a plurality of upper cells that each have a hemispherical shape and an ice making tube disposed at outer circumferential surfaces of the upper cells and configured to cool each of the upper cells. The ice maker also includes a lower tray that includes a plurality of lower cells that each have a hemispherical shape. The lower tray is rotatably connected to the upper tray. The ice maker further includes a rotation shaft connected to a rear end of the lower tray and a rear end of the upper tray, and configured to rotate the lower tray with respect to the upper 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 water pocket with an open top side is filled with water, mounted in a regular position on a supporting frame, and tilts to supply the water stored in the water pocket to an ice making tray, thereby easily supplying a required amount of water to the ice making tray. A refrigerator includes an ice making tray provided to linearly move with rotation when ice of the ice making tray is separated, or includes a holding preventing member which prevents the ice from being caught by a lower ice making tray, thereby improving a forward-and-backward width of an ice maker. It is possible to easily withdraw ice stored in an ice bucket by pushing an ice discharge button in a state in which the ice bucket is not separated.

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.

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-tray for ice-making machines is formed by modular fabricated cups that can assembled together within a frame to create an ice-tray of arbitrary dimensions allowing a sharing of components among a variety of ice-tray sizes. Individual cups may include ice formation sensors or heaters or may be heated by an induction heating system.

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.

An ice maker assembly includes an ice making apparatus for an appliance with an ice making tray having a water basin formed by a metallic ice forming plate and at least one perimeter sidewall extending upwardly from a top surface of the ice forming plate. The ice making tray also has a grid with at least one dividing wall. The at least one perimeter sidewall and the at least one dividing wall and the top surface of the ice forming plate form at least one ice compartment having an upper surface and a lower surface. An ice body is formed in the at least one ice compartment. Moreover, the at least one perimeter sidewall and the at least one dividing wall form a draft angle with the top surface of the ice forming plate, of about 17 degrees to about 25 degrees.
