Refrigerator

An ice maker comprising:

• a first tray having a first section of a cell, the cell extending in an X-axis direction, a Y-axis direction, and a Z-axis direction respectively;
• and
• a second tray having a second section of the cell, the first section and the second section of the cell being configured to define a space of the cell to receive a liquid to be phase-changed to form ice,
• wherein:
• the Z-axis direction is a direction that the first section of the cell and the second section of the cell are arranged in,
• the cell includes a plurality of cells, the X-axis direction being a direction that one cell of the plurality of cells and another cell of the plurality of cells are arranged in,
• the Y-axis direction is a direction that is orthogonal to the Z-axis direction and the X-axis direction, and
• an X-Y axis cutting plane of the second tray is a plane cutting the second tray in the X-axis direction and the Y-axis direction, when the second tray is at an ice making position,
• wherein:
• the second tray comprises a first portion forming the second section of the cell and a second portion extending from the first portion, the first portion being integrally formed with the second portion,
• the second portion includes a first extension part extending from the first portion in a first Y direction and a second extension part extending from the first portion in a second Y direction,
• each of the first and second extension parts has a curved portion in the X-Y axis cutting plane of the second tray,
• the first portion and the second portion of the second tray are made of a flexible or soft material, and
• a curvature change rate of a portion of the first extension part in the X-Y axis cutting plane of the second tray includes a portion different from a curvature change rate of the second extension part in the X-Y axis cutting plane of the second tray,
• wherein a curvature change rate of an inner line of the first extension part in the X-Y axis cutting plane of the second tray is different from that of an inner line of the second extension part in the X-Y axis cutting plane of the second tray, when the second tray is at the ice making position, and
• wherein the inner line of the first extension part is connected to the inner line of the second extension part, or the inner line of the first extension part includes a portion that overlaps the inner line of the second extension part in the Y-axis direction.
