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.

A refrigerator includes a cabinet defining an interior volume and a door for accessing the interior volume. An ice maker is disposed within the interior volume harvesting ice. The ice maker includes a frame and a motor. An ice tray includes a first end engaged with the motor, a second end engaged to the frame and a plurality ice wells defined by a plurality of weirs including first and second sets of weirs positioned proximate the first and second ends respectively, and interior weirs positioned therebetween. Each of the first and second sets of weirs and the internal weirs include a passage bifurcating each weir into first and second weir portions. Each of the passages defined by the first and second sets of weirs have a cross-sectional area that is greater than a cross-sectional area of any one of the passages defined by the internal weirs.

Provided is a refrigerator including a cabinet having a refrigerating compartment and a freezing compartment defined therein, and an ice maker disposed in the freezing compartment, wherein the ice maker includes an upper tray made of an elastic material, and having a plurality of hemispherical upper chambers defined therein, a lower tray made of an elastic material, wherein the lower tray comes into contact with the upper tray by pivoting to define a plurality of spherical ice chambers therebetween, a driver for pivoting the lower tray to open and close the upper tray and the lower tray, and each rib formed along a circumference of each upper chamber or each lower chamber in contact with each other.

An ice maker for fitting into a cooling or freezing appliance includes an ice-making tray which forms a plurality of ice-piece-producing cavities for producing one ice piece each. An air channel is formed above the ice-making tray, which serves to guide a cold air stream. There is provided a heat-dissipating structure including a metal material and having a plurality of heat-dissipating pins, each of which, in a freezing phase, projects from above, with a pin tip leading, into one of the ice-piece-producing cavities. In some embodiments, the heat-dissipating pins extend into and through the upper air channel, so that the cold air flowing in the air channel flows around shaft portions of the heat-dissipating pins situated inside the air channel. When the ice-piece-producing cavities are filled with water, the heat-dissipating pins immersed in the water ensure improved dissipation of thermal energy from the water, which accelerates freezing.

A refrigeration appliance includes a freezer compartment for storing food items. An ice maker is disposed within the freezer compartment and includes a removable ice bin having an internal cavity. A front cover closes a front open end of the ice bin. The front cover includes a front face oriented toward a front of the freezer compartment, a rear face, and a recess formed in the rear face. The rear face of the front cover is disposed adjacent to a horizontal edge portion of the ice maker when the removable ice bin is disposed within the ice maker wherein the recess defines a gap between the front cover and the horizontal edge portion that fluidly communicates with the internal cavity of the removable ice bin. A plurality of ribs is disposed within the gap for directing air exiting the internal cavity of the removable ice bin into a predetermined direction.

An ice maker includes a harvest motor and an ice tray operably coupled to the harvest motor. The ice tray has a plurality of heat sinks coupled to a bottom section of ice forming cavities on the ice tray. The harvest motor is operable to twist the ice tray for causing the plurality of heat sinks to move relative to each other for releasing ice pieces from the ice forming cavities.
