The present embodiment has the above-mentioned structure,
Next, the operation will be described. When housing the cooling unit 25, the front panel 75 is opened and the board 2
6 is placed on the receiving plate 20 and pushed in, and the cooler 35 and the condensing unit 30 are separately stored in the cooling chamber 16 and the storage space 19. Specifically, the cooler 35 is inserted into the cooling chamber 16 through the entrance / exit 18, and when inserted by a predetermined amount, the left and right contact edges 52 of the support fitting 50 are placed on the receiving portions 58 of the left and right rails 55. Here, the front end side in the insertion direction of the cooler 35 is slightly inclined downward,
Even if the user swings his / her head to the left and right, the contact edge 52 of the support fitting 50 hits the guide 60, and the attitude of the cooler 35 is corrected by being guided by the guide 60, and the cooler 35 rides on the receiving portion 58.

When further pushed in, both contact edges 52 of the support fitting 50 are suspended and supported by the receiving portions 58 of the rails 55 and slide on them, so that the cooler 35 is held in a predetermined horizontal posture and the cooling chamber is maintained. 16 is inserted. At the end of the insertion, the mounting bolts 45 projecting from the front wall of the cooling chamber 16 are inserted into the insertion holes 46 of the cooling chamber lid 34, and are pushed to a predetermined position.
While fitting in the escape groove 18A, the cooling chamber lid 34 abuts the front wall of the cooling chamber 16 via the heat insulating packing 44, and a nut (not shown) is attached to the projecting end of the mounting bolt 45 penetrating the cooling chamber lid 34. When screwed in and tightened, the cooling chamber lid 34 hermetically closes the inlet / outlet 18 of the cooling chamber 16. The substrate 26 is fixed to the receiving plate 20 in the same manner as described above, whereby the cooler 35 is housed in the cooling chamber 16, while the condensing unit 30 is housed in the housing space 19. Finally, the front panel 75 is closed and the storage of the cooling unit 25 is completed.

When the condensing unit 30 and the cooling fan 40 are driven in accordance with the cooling operation, the air in the refrigerating compartment 11 passes through the return path 49 and the cooler 3 as shown by the arrow in FIG.
After being sucked from the intake port 38 on the lower side of 5 and converted into cool air, it is blown out from the cooling fan 40 to the ceiling surface side of the refrigerating compartment 11 through the upper surface of the guide plate 47, that is, the refrigerating compartment 1
Cold air is circulated and supplied to 1. At this time, the refrigerator compartment 11
A part of the air sucked from the inside does not pass through the inside of the cooler 35, but between the cooler 35 and the left side wall 16B as seen from the front of the cooling chamber 16 as shown by the dashed line in FIG. Rise,
There is a possibility that a short cycle may occur, such as returning to the inside of the refrigerating chamber 11 through a gap between the upper surface of the cooler 35 and the ceiling surface 16A of the cooling chamber 16. However, the rail 55 is attached to the ceiling surface 16A of the cooling chamber 16, and this functions to close the gap between the rail 55 and the upper surface of the cooler 35, and the above short cycle is prevented as much as possible.

For maintenance and the like, the cooling unit 25
To take out, open the front panel 75 and then
The nut that fixes the cooling chamber lid 34 is removed, and the screw 32 that fixes the substrate 26 is also removed. Then, the upper and lower handles 26A and 26B are reached and the cooling unit 25 is pulled out. During this time, the cooler 35 is in the same manner as when the cooler 35 is being inserted.
Both contact edges 52 of 0 slide while being suspended and supported by the receiving portion 58 of the rail 55, and are smoothly drawn out from the inlet / outlet 18 of the cooling chamber 16 while being held in a predetermined horizontal posture.

As described above, in this embodiment, the following various advantages can be obtained. Support bracket 50
Is suspended and supported by rails 55 so that it is prevented from inclining downward, and hanging portions 57 of both rails 55 are also restrained from swinging, so that the cooler 35 is held in a fixed posture in the cooling chamber 16. Be stored. Therefore, the flow path of the cool air and the like can be secured in a predetermined manner to enhance the cooling performance, and the refrigerant pipe 42 can be prevented from being pushed and bent. further,
It is also possible to prevent the defrosting heater provided in the cooler 35 from approaching the heat insulating portion and degrading the heat insulating portion, or defrosting water from concentrating and flowing in one place during defrosting.

When the cooling unit 25 is taken in and out,
There is no risk that the cooler 35 will interfere with other parts such as the drain pan 43, and the operation of putting in and out can be performed smoothly. Since the contact edge 52 of the support fitting 50 is placed on the receiving portion 58 of the rail 55 and slides in line contact along the inserting / removing direction, the frictional resistance between the support fitting 50 and the rail 55 is suppressed to be small, Putting in and out of the cooling unit 25 becomes easier. Since the support fitting 50 is provided on the front end side in the insertion direction of the cooler 35, the distance that the support fitting 50 can be received by the rail 55 can be utilized to the maximum, and more stable loading and unloading can be achieved. On the other hand, since the cantilevered projecting end is suspended, the load applied to the rail 55 can be suppressed to be small.

The support fitting 50 has a shape in which the upper edges of the left and right side plates 51 are bent obliquely downward to the outside, and the contact edge 52 is provided at the tip, so that the bent portion functions as a spring. When the cooling unit 25 is transported in a housed state, a cushioning effect against a vertical impact can be obtained. Further, since the rail 55 closes the gap between the upper surface of the cooler 35 and the ceiling surface 16A of the cooling chamber 16, the air inside the refrigerator does not pass through the inside of the cooler 35 but returns to the inside of the refrigerating chamber 11 through the above-mentioned gap. Such a short cycle is prevented as much as possible, and the cooling efficiency in the refrigerating compartment 11 can be improved.
