    摘要： Provided is a refrigerator. The refrigerator includes: a storage chamber configured to store food; a cooler configured to supply cold into the storage chamber; a first tray assembly configured to define a portion of an ice making cell that is a space in which water is phase-changed into ice by the cold; a second tray assembly configured to define another portion of the ice making cell, the second tray assembly being connected to a driver to contact the first tray assembly in an ice making process and to be spaced apart from the first tray assembly in an ice separation process; a heater disposed adjacent to at least one of the first tray assembly or the second tray assembly; and a controller configured to control the heater and the driver. The controller controls the heater to be turned on in at least partial section while the cooler supplies the cold so that bubbles dissolved in the water within the ice making cell moves from a portion, at which the ice is made, toward the water that is in a liquid state to make transparent ice.

    摘要： A refrigerator of the present invention comprises: a storage chamber for storing food; a cool air supplying means for supplying cool air to the storage chamber; a first tray which forms a part of an ice-making cell in which water is phase-changed to ice by the cool air; a second tray which forms another part of the ice-making cell and can be in contact with the first tray during an ice-making process; a water supply valve for adjusting a flow of the water supplied to the ice-making cell; a water supply amount detector for detecting the amount of water supplied to the ice-making cell; and a controller for controlling the water supply valve. The controller controls the water supply valve to supply water to the ice-making cell as much as a first reference water supply amount, for supplying water to the ice-making cell at a water supply position of the second tray. After finishing the water supply as much as the first reference water supply amount, the controller moves the second tray to an ice-making position and determines whether the water supply amount of the ice-making cell has reached a target water supply amount by using the water supply amount detector. When the water supply amount of the ice making cell has reached the target water supply amount, the controller starts ice-making, and when the water supply amount of the ice making cell has not reached the target water supply amount, the controller moves the second tray back to the water supply position and controls the water supply valve to supply water as much as a second reference water supply amount which is less than the first reference water supply amount.

    摘要： 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.

    摘要： The refrigerator of the present invention comprises: a storage compartment where food is stored; a cold air supply means for supplying cold air to the storage compartment; a first tray forming a part of an ice making cell which is a space where water phase-changes into ice by the cold air; a second tray which forms another part of the ice making cell and which can be brought into contact with the first tray during an ice making process, and which is connected to a driving unit so as to be spaced apart from the first tray during an ice separating process; a heater positioned adjacent to at least one of the first tray and the second tray; an ice bin for storing ice dropped from the ice making cell; a full ice level sensing means for sensing a full ice level of the ice bin; and a control unit for controlling the heater and the driving unit.
    When the full ice level of the ice bin is sensed by the full ice level sensing means, the control unit controls the driving unit such that the second tray moves to the ice separating position after the ice making is completed.

    摘要： The refrigerator may comprise: a first tray assembly forming a part of ice-making cells; and a second tray assembly forming the other part of the ice-making cells. In order that ice can be produced in the direction of ice-making cells formed by any One of the first and second tray assemblies to ice-making cells formed by the other tray assembly, following the start of an ice-making process, the one tray assembly comprises a first part, and the first part comprises: a first surface forming a part of the ice-making cells; and a first deformation-resistant reinforcement part extending from the first surface in the vertical direction away from a heater.
