FIG. 9 is an overall front view showing a conventional automatic ice maker 10. The automatic ice maker 10 includes an ice making chamber 12 in which an ice making mechanism (not shown) is provided, and a refrigeration mechanism 14. The machine room 16 is arranged side by side. In the automatic ice making machine 10, a common top panel 18, bottom panel 20, and back panel 22 are used in the ice making room 12 and the machine room 16, and the ice making room 12 and the machine room 16 are partitioned by a partition wall 24. .

Defined. Further, an opening 32 is provided at a portion corresponding to the front surface of the machine room 16 in the automatic ice making machine 10, and the opening 32 is closed by a detachable front panel 34. As shown in FIG. 10, the refrigeration mechanism 14 disposed in the machine room 16 includes a condenser 36 disposed so as to face the opening 32, and a compressor disposed behind the condenser 36. The cooling fan 40 is fixed to the condenser 36 via the shroud 42 between the condenser 36 and the compressor 38.

  Above the machine room 16, a cubical electrical box 44 is provided. The electrical box 44 includes an outer box 46 that forms an outer shell, and a storage box 48 that is provided inside the outer box 46 and stores various electronic components (not shown). The outer box 46 is fixed between the two front frames 26, 26, and the upper side of the opening 32 is closed by the outer box 46. The storage box 48 is set to be slightly smaller in size than the outer box 46, and is disposed with a required space between the outer box 46.

The front part of the second electrical box 112 is fitted and fixed to the cutout part 108 a of the first heat insulating material 108 when the opening 98 is closed by the front panel 100.

(Operation of Example)
Next, the effect | action of the cooling structure of the machine room in the storage which concerns on an Example is demonstrated. When the cooling fan 122 is activated, external air is sucked into the lower space 116 of the machine room 64 through the suction port 102 of the front panel 100. Then, the air flows between the refrigerant pipes 128 of the condenser 120 and is sent backward.

  Part of the air that has passed through the refrigerant pipe 128 rises via the side flow passage 164 and flows into the upper space 118 of the machine chamber 64. The remaining air flows rearward through the lower space 116 and rises along the back panel 74. Then, the air rises in the backward flow passage 166 to reach the upper space 118 and flows forward. In addition, the air flowing into the upper space 118 from the side flow passage 164 merges with a part of the air flowing into the upper space 118 from the rear flow passage 166 and passes through the heat exchange port 154 to the first electrical box 114. Enter inside. The air that has flowed into the first electrical box 114 exchanges heat with the electronic components, and then returns to the upper space 118 again through the heat exchange port 154 and is discharged from the discharge port 104 of the front panel 100. At this time, since the first electrical component box 114 uses a part of the partition plate body 146 as the bottom, the heat in the first electrical component box 114 is easily radiated through the partition plate body 146. In addition, the heat in the first electrical box 114 is radiated through a plate-like member 148 provided upright on the partition plate 110. At this time, since the first heat insulating material 108 closes the space between the front panel 100 and the partition plate 110, the air that has become hot due to heat exchange in the machine room 64 descends through the space of the front panel 100. However, it is not taken into the lower space 116 again. The second electrical component box 112 is also placed on the partition plate main body 146, so that the heat in the second electrical component box 112 can be radiated through the partition plate main body 146.

  On the other hand, a part of the air flowing into the upper space 118 through the rear flow passage 166 circulates forward through the left and right distribution spaces 168 and 168 as shown in FIG. Heat exchange takes place. And the air which distribute | circulates the distribution space 168 on the right side is discharged | emitted from the discharge port 104 of the front panel 100 outside. On the other hand, the air flowing through the left distribution space 168 is guided to the side discharge port 106 by the distribution space 168, and the air is discharged from the side discharge port 106 to the space A. Then, as shown in FIG. 1, the air heated to a high temperature by exchanging heat in the machine chamber 64 flows to the left along the space A, and dew adheres to the pull portion 88 and the packing 92. To prevent.

  Thus, the air taken in from the lower space 116 side of the machine room 64 flows in the counterclockwise direction shown in FIG. 8 inside the machine room 64, so that the entire machine room 64 is air-cooled. Can do. Therefore, the machine room 64 can be efficiently cooled, and the temperature rise in the machine room 64 can be suppressed, so that the capacity reduction of the refrigeration mechanism 65 can be prevented. In addition, since air flows around the first and second electrical boxes 114 and 112 to exchange heat, the electrical boxes 114 and 112 do not need to have a double box structure as in the prior art, and the number of parts is reduced. obtain. Further, since the intake / exhaust from the front panel 100 side is enabled, the back panel 74 and the right side panel 97 of the automatic ice maker 60 can be installed in close contact with the wall of the installation location, and the installation location is limited. There is nothing.

In addition, by providing the first heat insulating material 108 at a substantially central portion in the vertical direction of the front panel 100, the strength of the front panel 100 can be improved and deformation of the panel 100 can be suppressed. Further, the first heat insulating material 108 abuts against the front piece 152, so that the front panel 100 is prevented from rattling and functions as a buffer when an external force is applied to the front panel 100. It can avoid that 100a dents.

  In the embodiment, since the condenser 120 is sandwiched between the left and right second heat insulating materials 134, 134, the condenser 120, the shroud 136, etc. are fixed, and the generation of noise due to vibration can be reduced. Further, since the condenser 120 is fixed by the second heat insulating materials 134 and 134, the use of screws or the like can be minimized, and the efficiency of the assembly work can be improved. Further, in the embodiment, high temperature air can be discharged from the side discharge port 106 to prevent dew from the handle portion 88, the packing 92, and the like, so that the growth of mold and germs can be suppressed and is hygienic. In addition, by preventing dew on the packing 92, it is possible to prevent the condensed water from dripping into the ice storage. Furthermore, since the dew condensation is prevented using the refrigeration mechanism 65 and the first and second electrical equipment boxes 114 and 112, the running cost does not increase.

  In the embodiment, the side flow passage 164 is formed between the partition plate 110 and the right side panel 97. However, the side flow passage 164 is not necessarily provided, and only the rear flow passage 166 is formed. May be. In the embodiment, the back panel 74 is not provided with a discharge port for discharging air. However, the pack panel 74 is provided with a discharge port to discharge air from both the front panel 100 and the back panel 74. It is good. Furthermore, in the embodiment, the first electrical equipment box 114 is configured by the cover member 158, the plate-shaped member 148, and the like, and is configured to be integrally attached to the partition plate 110. However, a box-shaped first electrical equipment box may be prepared separately and arranged separately on the partition plate 110.

  In the embodiment, the automatic ice making machine 60 that manufactures ice blocks as a storage has been described as an example, but a refrigerator may be employed as the storage. Moreover, although the case where the opening part 98 of the machine room housing | casing 70 was provided in the front side was shown in the Example, you may provide the opening part 98 opened to the right side, for example. In this case, a suction port 102 and a discharge port 104 are provided in the right side panel 97 so that air is sucked and exhausted from the right side panel 97 side.
