Direct blowing of high-temperature air to low-temperature parts such as the ice storage 16 and the water storage tank 22 can be avoided, and problems such as a decrease in ice-making efficiency and accelerated melting of stored ice can be prevented. In addition, it is possible to suppress a rise in the ambient temperature of the electrical equipment box 23,
The occurrence of failures in control systems, etc. can be reduced.

Various parts constituting the ice making mechanism and cooling unit described above are housed within the main body 1A. The front portion of the main body 1A is composed of a bent main front plate 4a and a lower front plate 4b that covers an opening 30 formed in the lower part of the main front plate 4a.

Next, the structure of the front portion of the main body, which is the gist of the present invention, will be explained.

The lower front plate 4b is slightly larger than the opening 30, and is placed against the opening 30 from the front side. Then, the upper edge and left and right side edges of the lower front plate 4b come into contact with the mouth edge of the opening 30, that is, the upper edge and left and right edges of the opening 30, and as shown in FIG. The upper edge of the lower plate 4b and the main front plate 4a are fixed to the angle 2b. On the other hand, the lower end of the front lower plate 4b is attached and fixed in relation to the drainage device 35.

As shown in FIG. 3, the drainage device 35 includes a drainage tray 36 having a downward projecting edge 37 projecting around its periphery, and a cylindrical drainage port 38 integrally projecting from approximately the center of the bottom surface. and is removably fitted into this drainage tray 36,
A drainboard 39 whose position is determined at a predetermined height by supporting legs 39a, 39a at both ends is shaped like a box with a bottom, and the drain tray 36 is removably attached to its upper opening edge 40a by its protruding edge 37. A drainage tray support 40 and a drainage hose 44 whose connection port 45a is removably connected from the outside to the drain port 38 of the drainage tray 36 to discharge drain water accumulated in the drainage tray 36 from the tip port 45b. Become. Drain hose 44
The drain tray support 40 with the drain hose 44 installed therein is placed on the bottom plate 7 extending forward of the main body 1A, and the end opening 45b of the drain hose 44 is inserted into the opening 47 formed in the bottom plate 7 to position it. has been done. That is, a notch 41 is formed in the rear side wall 40b of the drain tray support 40 to allow the drain hose 44 to pass through and project to the outside, and the distal end 45b of the drain hose 44 is attached and positioned through the notch 41 and the opening 47. has been done. Further, a projecting wall portion 42 extending horizontally inward is formed at the upper end of the rear side wall 40b. This projecting wall portion 42 serves as a support wall for fixing the lower portion of the lower front plate 4b.

On the other hand, the front lower plate 4b has a horizontal portion placed on the projecting wall portion 42 at its lower end, and a horizontal portion placed on the projecting wall portion 42.
A bent part 51 is formed, and the lower end of the vertical part, which is the tip of the bent part 51, is formed into a double fold 50.

Therefore, when the front lower plate 4b is covered with the opening 30, the bent portion 51 of the front lower plate 4b is bent as shown in FIG.
The horizontal part of the holder is placed on the protruding wall part 42, and the stopper part is abutted and locked on the front end of the protruding wall part 42. As a result, when there is no bent part 51, the lower end of the front lower plate 4b goes too far into the opening 30, and the left and right front surfaces of the main front plate 4a that sandwich the opening 30 and the surfaces of the lower front plate 4b are uneven. This eliminates the inconvenience of assembling the main front plate 4, which made it difficult for the main front plate to be on the same surface.
The lower front plate 4b can be positioned so that the lower front plate 4b and the lower front plate 4b are substantially on the same plane.

After positioning the front lower plate 4b in this way,
Two screws 31b are tightened through the holes opened in the horizontal portion of the bent portion 51 into the screw holes 43, 43 (see FIG. 3) of the protruding wall portion 42 to mount and fix the lower front plate 4b.

Here, the bent portion 51 provided on the front lower plate 4b
As mentioned above, in addition to the positioning function, during maintenance of the device, after removing the screws 31b, when removing the front lower plate 4b, there is a handle that can be easily removed by hooking your finger on the vertical lower end of the bent portion 51. It can be used as That is, the bending portion 5
The vertical lower end of 1 extends below the projecting wall part 42,
It allows you to put your finger on it. Since troubleshooting and service inspection of internal mechanical parts such as the ice making section are carried out through this opening 30 that appears after removing the front lower plate 4b, easy removal of the front lower plate 4b improves the workability. Further, by making the end of the bending portion 51 double-folded 50, it is possible to prevent the risk of injury when the fingers are hung.

With the above configuration, the ice release lever 1
When 9 is pushed rearward with a cup or the like, the ice release command switch 20 is turned on, the ice release member is rotated via the auger motor 14, and the door member 18 is opened. Therefore, ice pieces are discharged from the shooter 17 through the opened ice discharge port. Even if the ice that does not fit into the cup or the cup is released from the ice release lever 19, a small amount of ice that does not fit into the cup or the cup that falls is released by the door member 18 that is operating the delayed opening operation, and water that has spilled from the cup is drained into the drain tray 36. The water is drained out of the machine through the drain hose 44.
