a second case configured to be moved inside the cover frame, and to receive the second tray.
4. The refrigerator of claim 3 , further comprising:
a rack gear connected to the second case and configured to be moved relative to the cover frame,
wherein the second case is moved horizontally with respect to the cover frame in conjunction with a movement of the rack gear.
5. The refrigerator of claim 4 , further comprising:
a driver configured to generate power; and
a pinion configured to be rotated according to a drive of the driver;
wherein the pinion and the rack gear are engaged to convert a rotational motion of the driver into a linear motion.
6. The refrigerator of claim 4 , further comprising:
an elastic member to connect the rack gear to the second case,
wherein in response to the rack gear being maximally moved in a direction in which the second case moves toward the first case, the elastic member is tensioned and airtightness between the second case and the first case is maintained by an elastic restoring force.
7. The refrigerator of claim 3 , further comprising:
a first ejector including a pressing portion,
wherein the first case includes a plurality of through holes corresponding to positions of the plurality of first ice-making cells, and
the pressing portion is configured to pass through the plurality of through holes so as to press the first tray.
8. The refrigerator of claim 7 , wherein
the first ejector includes:
a body configured to support the pressing portion, and
a leg extending from each of opposite ends of the body and inserted into respective side portions of the cover frame,
the second case includes:
a protrusion extending from each of opposite ends of the second case to be respectively received in the legs, and
in response to the second case being moved in a direction away from the first case, the protrusions interfere with the legs, and the first ejector is moved in a direction closer to the first case such that the pressing portion presses the first tray.
9. The refrigerator of claim 7 , further comprising:
a second ejector fixed to one side of the cover frame and including a pressing portion extending toward the second case,
wherein in response to the second case being moved in a direction away from the first case, the pressing portion of the second ejector passes through the second case so as to press the second tray.
10. The refrigerator of claim 1 , wherein
each first ice-making cell of the plurality of first ice-making cells of the first tray and each second ice-making cell of the plurality of second ice-making cells of the second tray are configured in a semi-spherical shape.
11. The refrigerator of claim 1 , further comprising:
a cover frame coupled to an inside of the ice-making housing; and
a water path configured on an upper surface of the cover frame to guide the water supplied from the water supplier to flow into the first tray and the second tray.
12. The refrigerator of claim 11 , wherein
the water path includes a plurality of flow paths to equally supply water to each first ice-making cell of the plurality of first ice-making cells of the first tray and each second ice-making cell of the plurality of second ice-making cells of the second tray.
