Description

Refrigerator This specification relates to a refrigerator. Generally, a refrigerator is a home appliance that allows food to be stored at low temperatures in an internal storage space enclosed by a door. The above refrigerator can store stored food items in a refrigerated or frozen state by cooling the interior of the storage space using cold air. Typically, refrigerators are equipped with an ice maker for making ice. The above ice maker generates ice by collecting water supplied from a water source or water tank into a tray and then cooling the water. In addition, the ice maker can remove the ice that has been frozen from the ice tray by a heating method or a twisting method. The ice maker, which automatically supplies and releases water in this manner, is formed to open upwards and scoops up the formed ice. Ice produced by an ice maker of this structure has at least one flat surface, such as a crescent shape or a cubic shape. Meanwhile, if the ice is formed in a spherical shape, it can be more convenient to use and provide the user with a unique user experience. In addition, when storing the ice, the contact area between the ice cubes can be minimized, thereby minimizing the clumping of the ice. An ice maker is disclosed in Korean Registered Patent Publication No. 10-1850918 (hereinafter referred to as "Prior Art 1"), which is a prior art document. The ice maker of Prior Art 1 comprises: an upper tray having a plurality of hemispherical upper cells arranged therein and a pair of link guide sections extending upward from both ends; a lower tray having a plurality of hemispherical lower cells arranged therein and rotatably connected to the upper tray; a rotation axis connected to the rear ends of the lower tray and the upper tray to cause the lower tray to rotate relative to the upper tray; a pair of links, one end of which is connected to the lower tray and the other end of which is connected to the link guide sections; and an upper ejecting pin assembly, each connected to the pair of links with both ends fitted into the link guide sections and moving up and down together with the links. In the case of Prior Art 1, spherical ice can be produced by a hemispherical upper cell and a hemispherical lower cell, but since the ice is produced simultaneously in the upper cell and the lower cell, the bubbles contained in the water are not completely discharged, and the bubbles are dispersed within the water, resulting in an opaque ice. A prior art document, Japanese Patent Publication No. JP 9-269172 (hereinafter referred to as "Prior Art 2"), discloses an ice-making device. The ice-making device of Prior Art 2 includes an ice-making plate and a heater that heats the bottom of the water supplied to the ice-making plate. In the case of the ice-making device of Prior Art 2, the water on one side and the bottom of the ice-making block is heated by a heater during the ice-making process. Therefore, solidification proceeds on the water surface side, and convection occurs within the water, so that clear ice can be produced. As the growth of transparent ice progresses and the volume of water within the ice block decreases, the solidification speed gradually increases, and sufficient convection suitable for the solidification speed cannot be generated. Therefore, in the case of prior art 2, when approximately 2/3 of the water has solidified, the amount of heating of the heater is increased to suppress the increase in the solidification speed. However, according to Prior Art 2, simply reducing the volume of water increases the heating amount of the heater, making it difficult to produce ice with uniform transparency depending on the shape of the ice.
