Ice maker for refrigerator

A refrigerator of the present invention comprises: a cabinet having a freezer chamber, and an ice maker provided in the freezer chamber, wherein the ice maker includes a tray for forming an ice chamber, and a case for supporting the tray, the case includes a fixing part to be fixed to walls for forming the freezer chamber or a housing fixed to the walls, and the fixing part includes an inclined surface so that the case forms a slope at the walls or the housing.

Refrigerator comprising fixing part

An ice maker includes an upper tray and a lower tray made of an elastic material. Upper chambers in the upper tray and lower chambers in the lower tray contact each other to define spherical ice chambers, respectively. An ejector-receiving opening is opened to each of the upper chambers. An opening-defining wall extends upward along a circumference of each ejector-receiving opening. An upper ejector passes through the ejector-defining wall and vertically moves to remove ice from the ice chamber, and a driver pivots the lower tray to open and close the upper tray and the lower tray. The upper tray includes a horizontal extension forming a top face of the upper tray, and 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.

Ice maker and refrigerator

An ice maker includes an upper assembly having an upper tray that defines upper portions of a plurality of ice making chambers. The ice maker also includes a lower assembly that is located vertically below the upper assembly and configured rotate relative to the upper assembly. The lower assembly includes a lower tray that defines lower portions of the plurality of ice making chambers, and a lower support that is configured to receive the lower tray and restrict an outward expansion of the lower portions of the plurality of ice making chambers. The lower tray includes a lower tray body configured to hold a first volume of water, and a circumferential wall that extends upward from the lower tray body and is configured to hold a second volume of water above the first volume of water.

An ice maker includes: an upper tray defining an upper chamber that is a portion of an ice chamber; a lower tray rotatable relative to the upper tray and defining a lower chamber that is another portion of the ice chamber disposed under the upper chamber; an upper heater disposed around the upper tray for providing heat to the upper chamber; and a lower heater disposed around the lower tray for providing heat to the lower chamber. In an ice making position, a distance from a horizontal central line passing a contact surface of the upper tray and the lower tray to the upper heater is shorter than a distance from the horizontal central line to the lower heater.

A refrigerator includes a cabinet defining a storage space, a door configured to open and close at least a portion of the storage space, and an evaporator configured to generate cold air. The refrigerator also includes a first ice maker provided in the door, a second ice maker provided in the storage space and configured to be covered by the door when the door is closed, a first cold air guide configured to guide the cold air to the first ice maker, and a second cold air guide configured to guide the cold air to the second ice maker.

Refrigerator

An ice maker of the present embodiment comprises: an upper tray including an upper tray body defining an upper chamber that is a portion of an ice chamber for generating ice; and a lower tray rotated relative to the upper tray based on a rotational center, and including a lower tray body defining a lower chamber that is another portion of the ice chamber, wherein a top surface of the lower tray body can contact a bottom surface of the upper tray body, the rotational center is disposed outside of the upper chamber and the lower chamber, the bottom surface of the upper tray body includes a first surface and a second surface disposed farther from the rotational center than the first surface, and before the top surface of the lower tray body contacts the bottom surface of the upper tray body, the second surface is lower than the first surface.

An ice maker of the present invention comprises: an upper tray defining an upper chamber that is a portion of an ice chamber, wherein an upper opening is provided in an upper side of the upper tray; a lower tray defining a lower chamber that is another portion of the ice chamber; a lower support supporting the lower tray and provided with a lower heater; and a control unit configured to operate the lower heater in an ice making process, wherein the control unit variably controls an output of the lower heater so that bubbles included in water in the ice chamber are gathered in a lowermost section in the ice making process.

Ice maker and method for controlling ice maker

A refrigerator includes a cabinet defining a storage space, a door configured to open and close at least a portion of the storage space, and an ice maker assembly provided in the storage space. The ice maker assembly includes an ice maker provided forward of a cold air discharge port that is provided at a rear portion of the storage space, where the cold air discharge port is configured to deliver cold air, a front cover that covers a front side of the ice maker and that is configured to be exposed to an outside of the cabinet based on the door being opened, and a heat insulating material provided at a rear surface of the front cover and configured to at least partially block the cold air passing through the ice maker from being delivered past a front surface of the front cover.

In a refrigerator, a cam of a cam gear rotating by a driving motor is provided with a structure protruding from an edge portion of a cam gear to a center, thereby increasing the thickness of a cam surface. Therefore, it is possible to reduce the magnitude of force directly transferred from the cam gear to a magnet lever.

Ice maker and a refrigerator including the same

An ice maker includes first and second trays configured to form a plurality of ice chambers configured to make ice, an upper case including a cool air hole through which cool air passes, and a tray opening configured to allow the first tray to contact the cool air passing through the cool air hole, a driver configured to move the second tray, and a connector configured to transfer power of the driver to the second tray, wherein the upper case further includes the cool air guide configured to guide the cool air passing through the cool air hole toward the tray opening.

A method controls a refrigerator including first and second trays defining an ice chamber, a driving unit for moving the second tray, an ice bin for storing ice produced in the ice chamber, and an ice-fullness detection means for detecting whether or not the ice bin is full of ice. The method includes supplying water to the ice chamber when the second tray is at a water-supply position, making ice after the second tray has moved to an ice-making position in an inverse direction after the water supply has been completed, determining whether the ice bin is full of ice after the ice making is completed, moving the second tray to an ice-separating position and then rotating in the inverse direction if it is not determined whether or not the ice bin is full of ice, and determining again whether the ice bin is full of ice after ice separation is completed.

The present invention relates to a refrigerator. An ice maker of the refrigerator according to this embodiment includes: an upper tray which is made of an elastic material and in which a plurality of hemispherical upper chamber are defined; and a lower tray which is made of an elastic material and in which a plurality of lower chambers, which rotate to be in close contact with the upper tray so as to provide spherical ice chambers, are defined.
