Abstract: 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.-

Abstract: The present invention relates to a refrigerator. The refrigerator of the present invention may include a first tray assembly configured to define one portion of an ice making cell, a second tray assembly configured to define the other portion of the ice making cell, and a heater disposed adjacent to at least one of the first and second tray assemblies, and a controller configured to control the heater. The controller controls the heater to be turned on so that ice is easily separated from the tray assemblies before the second tray assembly moves to the ice separation position in a forward direction.

Abstract: The refrigerator according to the present invention comprises: a storage compartment for storing food; a cooler for supplying cold to the storage compartment; a first tray assembly forming a part of ice-making cells which are where water changes phase to ice due to the cold; a second tray assembly forming the other part of the ice-making cells; a heater located adjacently to the first tray assembly and/or the second tray assembly; and a control unit for controlling the heater. Any one of the first and second tray assemblies has a greater degree of cold transfer than the other tray assembly.

Abstract: The present invention relates to a refrigerator. A refrigerator of the present invention may comprise: a first tray assembly forming a part of an ice making cell; and a second tray assembly forming another part of the ice making cell. The first tray assembly includes a first tray defining a part of the ice making cell and a first tray case supporting the first tray, and the second tray assembly includes a second tray defining another part of the ice making cell and a second tray case supporting the second tray. One of the first and second tray cases includes a first region having a through-hole and a second region having a shape corresponding to the ice making cell to support one of the first and second trays.

Abstract: 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.
