The inlet portion 125 and the outlet portion 126 may be arranged in a vertical direction. For example, the inlet portion 125 may be located higher than the outlet portion 126. Accordingly, cold air introduced through the inlet 125 may flow toward the second wall 124b located on the opposite side of the first wall 124a where the inlet 125 is located. As the cold air flows toward the first wall 124b, water supplied to the second ice maker 500 may be cooled.

Cold air flowing toward the second wall 124b may be diverted by the second wall 124b. The cool air whose direction has been changed flows toward the outlet 126. In the process of cold air flowing toward the outlet 126, the cold air may cool the ice stored in the second ice bin 600.

An inclined wall 124c may be provided below the second wall 124b. That is, the inclined wall 124c can facilitate changing the direction of cold air. The second ice bin 600 may include an inclined surface corresponding to the inclined wall 124c.

A receiving portion 127 for mounting the water tank 340a may be provided outside the second space 124 and adjacent to the inclined wall 124c. The receiving portion 127 may be covered by a receiving portion cover 128.
