Benefits of technology

The present invention relates to an ice making apparatus that can easily separate ice from a tray. The invention has advantages in that it can melt the ice surface by applying heat to both the upper and lower trays, which shortens the time for ice separation. Additionally, the invention allows for the production of transparent ice by removing bubbles from the lower portion of the ice. The invention also includes a control system to detect ice level, identify abnormal states, and resolve them in order to allow for stable ice separation. Overall, the invention improves the efficiency and quality of ice making.

Problems solved by technology

In the case of the prior document, the ice maker further include an ice separating heater for heating the upper cell for ice separation but when only the upper cell is heated, the time for ice separation becomes long and the separation of ice from the lower cell is not smooth.

Abstract

According to an embodiment of the present disclosure, a method for controlling a refrigerator, the refrigerator including an ice mater including a first tray and a second try provided in a storage space and coupled to each other to define a ice chamber and a driving part that rotates the second tray, a first heater provided in the first tray to heat the first tray, a second heater provided in the second tray to heat the second tray, and an ejector provided below the second tray to press an external portion of the second tray to separate ice from the second tray when the second tray is rotated for ice separation, and a controller that controls operation of the ice maker, the method including starting ice making by supplying water to the ice chamber; heating the second tray by turning on the second heater during ice making; heating the first tray by turning on the first heater for ice separation after completion of ice making; and heating the second tray by turning on the second heater for ice separation.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a refrigerator and a control method thereof.BACKGROUND ART[0002]In general, refrigerators are home appliances that allow low-temperature storage of food in an internal storage space that is shielded by a door.[0003]The refrigerator may cool the inside of a storage space using cold air, thereby storing stored foods in a refrigerated or frozen state.[0004]In general, an ice maker for making ice is provided in the refrigerator.[0005]The ice maker is configured to make ice by receiving water supplied from a water supply source or a water tank in a tray.[0006]In addition, the ice maker is configured to separate ice that has been made from the ice tray by a heating method or a twisting method.[0007]On the other hand, when the shape of the ice is formed in a spherical shape, it may be more convenient to use the ice and it is possible to provide a different feeling of use to the user. In addition, even when storing the produced ice, it ...
