Ice maker and control method therefor

A method of controlling an ice maker, the method comprising:

• controlling a driver connected to at least one of a first tray or a second tray of the ice maker to release coupling of the first tray and the second tray, so that ice is discharged from an ice-making container of the ice maker in which the first tray and the second tray are coupled;
• controlling the driver to couple the first tray and the second tray together;
• and
• operating, based on the coupling of the first tray and the second tray, a first heater of the ice maker provided adjacent to a sealing surface at which the first tray and the second tray are coupled or provided adjacent to a water supply guide, wherein the first tray comprises a first tray body, the first tray body comprising a protrusion that protrudes along the sealing surface toward the second tray.

An apparatus comprising:

• a container comprising a first tray and a second tray coupled to each other at a sealing surface between the first tray and the second tray, wherein the first tray comprises a first tray body, the first tray body comprising a protrusion that protrudes along the sealing surface toward the second tray;
• a water supply guide comprising a first end connected to the container, the water supply guide being configured to supply water to the container;
• a first heater adjacent to or in the container;
• and
• a second heater adjacent to or in the container, and at a position that is different than a position of the first heater,
• wherein the first heater is closer to the sealing surface than the second heater.
