Abstract
Disclosed herein are a refrigerator includes an ice making tray, a cooling system, a stirrer, at least a portion of which is submerged in the ice making tray, a stirring motor coupled to the stirrer, and a controller storing instructions and configured to execute the stored instructions to control the stirring motor to drive the stirrer while controlling the cooling system to cool water stored in the ice making tray. While the cooling system cools the water stored in the ice making tray, the stirrer stirs the water stored in the ice making tray.
Claims19
A refrigerator comprising:
- an ice making tray;
- a cooling system;
- a stirrer, at least a portion of the stirrer being submerged in the ice making tray, the stirrer comprising a stirring member and a scooping member, the stirring member having a different shape than the scooping member and being more flexible than the scooping member;
- a stirring motor coupled to the stirrer;
- and
- a controller storing instructions and configured to execute the stored instructions to control the stirring motor to drive the stirrer while controlling the cooling system to cool water stored in the ice making tray,
- wherein while the cooling system cools the water stored in the ice making tray, the stirrer is configured to stir the water stored in the ice making tray.
A control method of a refrigerator, the method comprising:
- supplying water to an ice making tray;
- stirring water stored in the ice making tray using a stirring member, at least a portion of which is submerged in the water while cooling the water stored in the ice making tray;
- and
- separating ice from the ice making tray using a scooping member having a different shape than the stirring member, where the stirring member is more flexible than the scooping member.
A refrigerator comprising:
- a first ice making tray having a first heat conductivity;
- a second ice making tray contacting a lower portion of a bottom surface of the first ice making tray and having a second heat conductivity;
- a cooling system contacting the second ice making tray;
- a stirrer, at least a portion of which is submerged in the first ice making tray;
- and
- a stirring motor coupled to the stirrer,
- wherein the second heat conductivity is higher than the first heat conductivity,
- wherein the stirrer comprises:
- a shaft;
- an ice-maker heater arranged inside the shaft;
- a stirring member protruding from the shaft and configured to stir water stored in the first ice making tray;
- and
- a scooping member protruding from the shaft and configured to separate ice from the first ice making tray.
