Refrigerator and control method therefor

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.

Description

technical field [0001] This instruction relates to a refrigerator and a control method thereof. Background technique [0002] In general, a refrigerator is a home appliance capable of storing food at a low temperature in an internal storage space shielded by a door. The refrigerator cools the inside of the storage space by using cold air, and can preserve the stored food in a refrigerated or frozen state. Generally, an ice maker for making ice is provided in the refrigerator. The ice maker accommodates water supplied from a water supply source or a water tank behind a tray, and generates ice by cooling the water. The ice maker can remove the ice that has been made from the ice tray by heating or twisting. [0003] An example of an ice maker that automatically supplies water and removes ice is formed so as to open upward so as to hold molded ice. [0004] The ice made in the ice maker with the above-mentioned structure has a flat surface at least on one side, such as a cr...

Problems solved by technology

[0014] However, according to the existing literature 2, it simply increases the heating amount of the heater when the volume of the water decreases, so it is difficult to produce ice with uniform transparency according to the shape of the ice.
