An ice making device includes a restriction mechanism for restricting an ice detection lever from moving to a lower side than a restriction position. The restriction mechanism includes a restriction member, a wire spring attached to the restriction member, an opening part and a protruded part provided in the frame. A restriction part of the restriction member is capable of moving between a first rotation position and a second rotation position. When the restriction member is located at the first rotation position, the protruded part elastically deforms the wire spring and urges the restriction member to the first rotation position and, when the restriction member is located at the second rotation position, the protruded part elastically deforms the wire spring and urges the restriction member to the second rotation position. When the restriction member is located at the second rotation position, the restriction part is disposed at the restriction position.

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.

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.

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 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 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 piece making assembly and a refrigeration appliance containing the ice piece making assembly is disclosed. The ice making assembly produces ice pieces by directional freezing and includes: an ice piece forming tray having a motor engaging end, a distal end, a first side, a second side and a bottom surface, a plurality of ice piece making compartments divided by divider walls, and a plurality of heat sinks engaged to the bottom surface of the ice making compartments and deliver defrost water to a drain or defrost water catch tray positioned at at least one of the distal end and the motor engaging end; and an ice piece forming tray canopy spaced a distance above the ice piece forming tray wherein the ice piece forming tray canopy comprises a heater and a temperature sensor.

The present invention relates to an ice making apparatus comprising a casing, ice trays, an ice receptacle, a retainer for rotatably supporting the ice trays and one or more than one knob for respectively twisting the ice trays either simultaneously or singly. In the ice making apparatus of the present invention, the retainer selectively supports either one of a plurality of exchangeable covers enabling a single or simultaneous twist type ice making apparatus. One exchangeable cover has a plurality of bearings.

A manual ice maker and a refrigerator comprising the same are provided. The manual ice maker comprises: an ice making body being a frame formed with an opening, and provided with a first positioning hole in a front wall thereof, a second positioning hole in a rear wall thereof and a first limiting protrusion on an inner surface of the rear wall thereof; an ice making tray provided with a first shaft at a front end thereof and a second shaft at a rear end thereof, the first shaft rotatably supported in and extended out of the first positioning hole, the second shaft rotatably supported in the second positioning hole; and an ice removing assembly. The ice removing assembly comprises: a twisting member provided with a gear; and a press member movable between a first position and a second position in a vertical direction to drive the gear to rotate.
