The control box fixing member 18 is formed from a metal plate having a substantially rectangular shape, and has a fixing piece 20 as shown in FIG. The fixing piece 20 is formed by bending the upper end of the control box fixing member 18 at a substantially right angle, and is screwed into the control box 10 from the upper surface of the control box 10 by a screw 22 inserted into the control box 10.
It is fixed to.

Also, the control box fixing member 1
8 has a pair of positioning parts 18a, 18a. These positioning portions 18a, 18a are formed by bending the side edges of the control box fixing member 18 at substantially right angles, whereby the side surface of the control box 10 is positioned at a predetermined position.

Also, the control box fixing member 1
8 has a horizontal base plate portion 23 that supports the lower surface of the control box 10. The base plate 23 extends horizontally from the lower end of the control box fixing member 18 and has a pair of guides 24, 24 (FIG. 6). These guide portions 24, 24 are formed by bending the side edges of the base plate portion 23 at substantially right angles, and are engaged with the side surfaces of the control box 10, respectively.

Also, the base plate portion 23 has a rear end 25
The rear end 25 is bent so as to face the rear surface of the control box 10. A small hole 16 for inserting the above-mentioned screw 22 into the control box 10 is formed on the upper surface of the control box 10.

In such a configuration, the top plate 1 of the main body 1
After removing all the screws from a, the front end of the top plate 1a is lifted by hand, and the top plate 1a pivots upward with the plate-like piece 26 projecting substantially horizontally from the rear surface of the main body 1 as a fulcrum,
Thereby, the upper surface of the control box 10 stored in the upper machine room 9 is exposed. After the upper surface of the control box 10 is exposed, the hand 22 is extended from the front of the main body 1 and the screw 22 is removed.
0 is free.

Therefore, when removing the control box 10 from the upper machine room 9 in order to repair the electrical components stored in the control box 10, it is necessary to remove many screws from the control box 10 or move the main body 1. Therefore, the control box 10 stored in the upper machine room 9 can be easily taken out from the upper machine room 9.

After all screws are removed from the top plate 1a of the main body 1, the front end of the top plate 1a is lifted by hand, and the control box 1 stored in the upper machine room 9 is lifted.
Since the upper surface of the control box 10 is exposed, the control box 10 can be removed from the upper machine room 9 without removing the top plate 1a from the main body 1.

Further, the side surface of the control box 10 is the positioning portion 1 of the control box fixing member 18.
8a and 18a, the fixing piece 2 of the control box fixing member 18 is positioned at a predetermined position.
When fixing 0 to the ceiling surface 10a of the control box 10, the small holes 16 formed in the upper surface of the control box 10 and the screw holes 21 formed in the fixing piece 20 can be easily aligned. Thus, the control box 10 can be easily mounted.

Also, the control box fixing member 1
8 fixed pieces 20 to the ceiling surface 1 of the control box 10
0a, the side surface of the control box 10 is positioned by the pair of guide portions 24 provided on the base plate portion 23 of the control box fixing member 18.
a, 18a, thereby preventing the electrical components stored in the control box 10 from being damaged by hitting the positioning portions 18a, 18a of the control box fixing member 18.

Further, the rear end 2 of the base plate 23
5 is bent so as to face the rear surface of the control box 10, so that the control box 1
When the control box 10 is taken out of the upper machine room 9, the rear surface of the control box 10 is brought into contact with the rear end 25 of the base plate portion 23 so that the control box fixing member 18 is removed.
It can be easily confirmed whether or not the fixing piece 20 has come out of the control box 10.

Also, the control box fixing member 1
Since the metal plate 8 is formed by bending a metal plate into an L shape, the shape of the heat insulating panel 29 can be maintained by the control box fixing member 18. Further, positioning portions 18a of the control box fixing member 18,
18a and the guide portions 24, 24 are formed by bending the side edges of the control box fixing member 18 and the base plate portion 23 at substantially right angles, so that the rigidity of the control box fixing member 18 can be increased. Thereby, the strength for keeping the heat insulating panel 29 in a predetermined shape can be secured.

Further, since the deformation of the horizontal plane 32a and the vertical plane 32b of the ice storage box 32 is suppressed by the deformation suppressing member 34, the horizontal plane 32a of the ice storage box 32, the lower surface of the heat insulating panel 29, and the vertical plane 32b of the ice storage box 32 are insulated. A gap can be prevented from being formed between the panel 29 and the front surface of the panel 29, thereby preventing the cool air from leaking from the ice making chamber 3 to the upper machine room 9.

Further, since both ends of the reinforcing plate 40 are fixed to the front end of the heat insulating wall 39 which forms the side of the ice making chamber 3, the side of the main body 1 can be reinforced by the reinforcing plate 40. The plate 1a can be easily screwed to the side surface of the main body 1.
