A refrigerator that includes a main body, an ice-making chamber formed inside the main body, an ice-making tray to store ice-making water and generate ice, and a refrigerant pipe installed so that at least a part thereof is in contact with the ice-making tray, wherein a refrigerant flows in the refrigerant pipe, wherein the ice-making tray includes an ice-making cell that stores ice-making water, and a temperature sensor accommodation portion that accommodates a temperature sensor that measures temperature of water or ice stored in the ice-making cell, and the temperature sensor accommodation portion includes an accommodation portion that is formed in a groove shape, and has an open upper side so that the temperature sensor moves in or out, and a fixing portion which is coupled to a wire connected to a part of the temperature sensor or to the temperature sensor and fixes a position of the temperature sensor.

The present disclosure relates to a refrigerator including a main body, a door, and an ice making chamber provided in the door and including an ice maker to make ice and an ice bucket to store the ice produced. The ice maker includes an ice making tray having a plurality of ice making cells for receiving water, an ice separation heater to heat the ice making tray so that ice is separated from the ice making tray, an ejector rotatably provided to transfer the ice separated to the outside of the ice making tray, and a water channel formed on partitions partitioning the plurality of ice making cells to allow water to flow between the partitions and configured such that at least one of surfaces in contact with ice has a tapered shape in which a thickness thereof gradually decreases in a direction of directing to the ice.

Disclosed is an ice making device that is able to selectively make ices having different transparencies from each other. The ice making device includes: an ice making chamber including an ice making container to accommodate ice making water therein; a cooler configured to supply cool air to the ice making chamber to cool the ice making water; an ice making fan configured to circulate the supplied cool air; an ice making heater configured to supply heat to the ice making water when the ice making water is cooled; and a controller configured to control at least one of the cooling unit, the ice making fan and the ice making heater to adjust a rate of change of temperature of the ice making container to generate one of two types of ice having different transparency.

A refrigerator utilizes a dual direction ice maker capable of overlapping multiple ice production cycles in time to accelerate ice production and/or routing ice to multiple storage bins.

An ice maker includes an ice tray, an ejector configured to rotate with respect to the ice tray and cause rotation of ice pieces, and a motor configured to drive the ejector to rotate relative to the ice tray. The ice tray includes a first guide rib located at a lower portion of the ice tray and configured to exchange heat with cool air supplied from a cool air inlet, and a second guide rib located at the lower portion of the ice tray and arranged at a center region of the lower portion of the ice tray. The ice tray defines a first area including the first guide rib, and a second area including both of the first and second guide ribs, where the first area of the ice tray is located closer to the cool air inlet than the second area.

An ice maker includes an ice tray, a motor configured to rotate with respect to the ice tray, an ejector configured to cause rotation of an ice piece, the ejector including a rotary shaft and a protrusion pin, a heater configured to selectively supply heat to the ice tray, and a first sensor unit configured to detect a rotation angle of the protrusion pin about an axis of the rotary shaft. The first sensor unit is further configured to, before discharge of the ice piece from the ice tray, detect whether the protrusion pin has rotated by a predetermined angle about the axis of the rotary shaft, and the heater is further configured to be turned off based on the first sensor unit detecting that the protrusion pin has rotated by the predetermined angle.

A refrigerator includes a fresh food compartment; a freezer compartment; an ice compartment disposed in the fresh food compartment; an ice maker disposed in the ice compartment, the ice maker including an ice tray, an ice maker evaporator, and a cooling tube which is disposed between the ice maker tray and the ice maker evaporator, such that the cooling tube is in direct contact with the ice maker tray and the ice maker evaporator; and a refrigeration circuit including a compressor, a condenser, a refrigerant valve, the ice maker evaporator, and a freezer compartment evaporator. The refrigerant valve directs a refrigerant to one of a first path or a second path of the refrigeration circuit, the first path causing the ice maker evaporator to work in series with the freezer compartment evaporator, and the second path causing the refrigerant to bypass the ice maker evaporator to the freezer compartment evaporator.

Disclosed are an ice maker, which can make ice with high transparency. The ice maker includes an ice making container configured to be filled with ice-making water; a heating ice-separator comprising a heating rod extended from above a water surface of the ice-making water into the ice making container so as to be immersed in the ice-making water and configured to transfer heat to the ice-making water, and a rotary shaft connecting with the heating rod, extended to traverse an upper portion of the ice making container, and configured to rotate the heating rod to be separated from the ice making container; and a heater configured to supply heat to the heating rod. By using the heater, the ice maker can not only make the ice with the high transparency, but also make ice-separation structure be simplified.

An ice maker assembly is disposed in the ice compartment of a refrigerator, the ice maker assembly including an ice maker tray/evaporator having an evaporator cooling tube which is in direct contact with an ice maker tray portion, and a tray temperature sensor for sensing a temperature of the ice maker tray portion. A controller is configured to control ice making, ice harvesting, and ice maintenance based on the temperature sensed by the tray temperature sensor. The tray temperature sensor is the only temperature sensor used to control ice making, ice harvesting, and ice maintenance. Alternatively, an additional temperature sensor can be disposed inside an ice maker assembly gear box for sensing a temperature of a housing of the gear box. In that case, the tray temperature sensor and the additional temperature sensor are the only temperature sensors used to control ice making, ice harvesting, and ice maintenance.

An ice maker provided in a refrigerator is provided. The ice maker includes: first and second ice making units configured to include ice making trays, heaters heating the ice making trays for deicing, and ejectors ejecting made ice from the ice making trays, respectively, wherein a plurality of first ice making grooves are formed in the ice making tray of the first ice making unit, and a plurality of second ice making grooves are formed in the ice making tray of the second ice making unit, the plurality of second ice making grooves having a shape different from that of the plurality of first ice making grooves.
