A base 26 is provided. The unit base 26 is slidable in the front-rear direction of the main body 11, and the refrigeration unit can be pulled out from the lower machine room 15 by pulling the unit base 26 forward.

The ice making apparatus shown in FIG. 1 has a water sprinkler 16 in the upper part of the ice making chamber 13, and the ice making water sprinkled from the water sprinkler 16 is provided in the evaporator provided in the lower part of the water sprinkler 16. After flowing down the surface of 17, it is stored in an ice making water tank 18 provided below the evaporator 17.
The ice making water tank 18 has a tray shape, and the ice making water stored in the ice making water tank 18 is repeatedly supplied to the water sprayer 16 by the circulation pump 20 until ice of a predetermined thickness is formed on the surface of the evaporator 17. It is supposed to be.

The circulating pump 20 has a pump section 20a, and one end of a water pipe 21 for supplying ice making water to the sprinkler 16 is connected to a discharge port of the pump section 20a. The circulating pump 20 has a motor section 20b for driving a pump section 20a. The motor section 20b is provided in an upper machine room 22 in the main body 1.

The upper machine room 22 is formed at the rear upper portion of the ice making room 13. The upper machine room 22 and the ice making room 13 are separated by an L-shaped heat insulating panel 23. The heat insulating panel 23 has a structure separate from the main body 11, and the evaporator 17 is mounted on the front surface thereof via a pair of left and right brackets 27. The heat insulating panel 23 forms a front wall and a bottom wall of the upper machine room 22. An ice guide plate 19 is provided between the evaporator 17 and the ice making water tank 18 for guiding the ice separated from the surface of the evaporator 17 to the front side of the ice making water tank 18.
