A refrigerator appliance includes an ice packer assembly including an enclosure with a rotatable door, and an ice mold slidably supported by the enclosure. The ice mold is configured to translate between a first position and a second position. The door is configured to rotate from a first orientation to a second orientation as the ice mold is translated from the first position to the second position. The enclosure defines a pass-through opening therethrough. The door opens up the pass-through opening when rotated to the first orientation, and closes the pass-through opening and defines a platform for receiving crushed ice thereon when it is rotated to the second orientation.

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.

A refrigerator includes a cabinet, an ice maker configured to make spherical ice, and an ice bin for storing the ice. The ice maker includes an upper assembly including a plurality of hemispherical upper chambers, a lower assembly disposed below and pivotably coupled to the upper assembly, wherein the lower assembly includes a plurality of hemispherical lower chambers that are configured to come in contact with the plurality of hemispherical upper chambers to define a plurality of spherical ice chambers, a driver configured to pivot the lower assembly, and an ice-full state detection lever that is coupled to and configured to be pivoted by the driver, wherein the ice-full state detection lever is configured to pivot in the same direction as the lower assembly to detect whether the ice bin is in an ice-full state.

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 maker for freezing water into ice pieces, the ice maker including an elongated cage having a central revolving axis about which the elongated cage revolves. The elongated cage having a first end, a second end and at least one elongated slot extending between the first end and the second end. An ice tray is configured to be received in the at least one elongated slot. The ice tray includes a plurality of cavities for receiving water to be frozen into ice pieces. A motor is coupled to the elongated cage for revolving the elongated cage about the central revolving axis. A controller is connected to the motor for controlling the revolving of the elongated cage about the central revolving axis.

A refrigerator includes a cabinet, an ice maker configured to make spherical ice, and an ice bin for storing the ice. The ice maker includes an upper assembly including a plurality of hemispherical upper chambers, a lower assembly disposed below and pivotably coupled to the upper assembly, wherein the lower assembly includes a plurality of hemispherical lower chambers that are configured to come in contact with the plurality of hemispherical upper chambers to define a plurality of spherical ice chambers, a driver configured to pivot the lower assembly, and an ice-full state detection lever that is coupled to and configured to be pivoted by the driver, wherein the ice-full state detection lever is configured to pivot in the same direction as the lower assembly to detect whether the ice bin is in an ice-full state.

In an ice making device, a frame supporting an ice tray and a drive unit has a first wall at a side of an ice detection member. Supported on the first wall is a regulation member rotatable between a first rotation position not to regulate coming down of the ice detection member and a second rotation position to regulate coming down of the ice detection member. By moving the regulation member to the second rotation position, later ice making is stopped even if ice accumulating below is not much. The regulation member includes a regulator in a circular arc form and is supported rotatably around a shaft. The regulation member as a rotary member is less liable to unexpectedly move from either of the first rotation position and the second rotation position, so that movement of the regulation member to a position not intended is suppressed.
