Ice-making machine with ice storage bin

An ice-making machine comprising:

• a box-shaped lower housing having an ice storage bin,
• a box-shaped upper housing mounted on a rear portion of the lower housing,
• an ice-making mechanism disposed within a front portion of a machine compartment in the upper housing, and
• a freezing unit disposed behind the ice-making mechanism and configured to supply liquid refrigerant to the ice-making mechanism,
• wherein an open-and-close lid is mounted on an opening formed between a lower end of a front face of the upper housing and an upper end of a front face of the lower housing,
• wherein an air intake passage is open at the front face of the lower housing and is configured to allow outside air introduced from the front face of the lower housing to flow as cooling air into the machine compartment through (a) a space between the ice storage bin and a first side wall of the lower housing and (b) a space between the ice storage bin and a rear wall of the lower housing, and
• wherein an air discharge passage is configured to allow air exhausted from the machine compartment after cooling the freezing unit through (c) a space between the ice storage bin and the rear wall of the lower housing, and (d) a space between a second side wall of the lower housing and the ice storage bin.
