On the upper surface of 8, a mounting frame 10 formed by filling a foam heat insulating material 26 into a space defined by a base plate 22 and a cooler mounting plate 24 is removably mounted. A compressor 28, a condenser fan motor, a condenser 30 and the like are mounted and mounted on the base plate 22 of the mounting base 10, and a cooler 32 vertically mounted on the cooler mounting plate 24.
Faces the storage chamber through the through hole 20.

To manufacture the mounting base 10, as shown in FIG. 5, a plurality of spacers 34 are fitted into a flat rectangular box-shaped base plate 22 obtained by bending a zinc iron plate.
A sealing material 36 such as a sponge is attached to the entire inner periphery of the base plate 22. Next, the cooler mounting plate 24 is opposed to the base plate 22 with a plurality of spacers 34 interposed therebetween, and a screw 38 is attached to each spacer 34.
After screwing in, the urethane foam raw material is injected and foamed into a space defined between the base plate 22 and the cooler mounting plate 24. Then, after the heat insulating material 26 is filled and subjected to the heat insulating treatment, the concave portion defined by the mounting plate 24 and the base plate 22 on the side of the cooler mounting plate 24 that contacts the ceiling wall 18 of the heat insulating box 16. The mounting frame 10 is obtained by fitting a heat insulating frame 42 made of a heat insulating material from below into 40.

[0004]

In the above-described mounting frame structure, the space between the inner surface of the base plate 22 and the outer edge of the cooler mounting plate 24, which define the space filled with the heat insulating material 26 via the spacer 34, is provided. 6, a slight gap 44 is inevitably formed due to the dimensional difference between the two. Therefore, in order to prevent the raw material from leaking when the urethane foam raw material is injected and foamed into the space, it is necessary to previously dispose the sealing material 36 on the inner surface of the base plate 22 as described above, and the number of parts increases. There was a problem that the cost increased. After the heat insulation treatment,
Since the heat insulating frame 42 is provided in a separate step, the number of work steps is increased, and there is a disadvantage that manufacturing efficiency is reduced. Furthermore, since the heat insulating frame 42 is only fitted in the concave portion 40,
When the refrigeration system 12 is detached from the freezer 14 during maintenance of the refrigeration system 12 attached to the freezer 14, it is pointed out that the heat insulating frame 42 is detached from the mounting base 10, and that a troublesome work of re-attachment is required.

[0005]

Has a flange 54 (see FIG. 2) extending horizontally outward along the open edges of the four side plates 52.
When the cooler mounting plate 24 is disposed on the base plate 2, a required gap 44 is defined between the inner surface of the side plate 48 of the base plate 22 and the outer edge of the flange 54 of the cooler mounting plate 24.

A heat insulating frame 42 made of a heat insulating material is detachably mounted on the flange 54 of the cooler mounting plate 24. The heat insulating frame 42 is mounted on the base plate 2.
And a main body 56 formed in a rectangular frame shape that can be inserted into the downwardly opened concave portion 40 defined by the side plate 48 of the second unit, the side plate 52 of the cooler mounting frame 24, and the flange 54.
And a protruding portion 58 protruding along the outer peripheral edge of the upper surface. As shown in FIG. 2, a groove 58 a into which the outer edge of the flange 54 of the cooler mounting frame 24 is inserted is formed on the inner surface of the protrusion 58.

[0011]

FIG. 3 shows another embodiment of the mounting base structure according to the present invention. The structure of the base plate 22 and the cooler mounting plate 24 is the same as that of the embodiment shown in FIG. Although they are the same, the structure of the heat insulating frame 42 is different. That is, the heat insulating frame 42 includes the four divided segments 60,
Each of the segments 60 has a projection 58 having a groove 58a into which the flange 54 of the cooler mounting plate 24 can be inserted. In this alternative embodiment, the four segments 60, 60, 60, 60 are mounted on the four edges of the flange 54 of the cooler mounting plate 24, respectively, and screwed and fixed to the base plate 22 as described above.
In this case, the gaps 44 defined between the base plate 22 and the cooler mounting plate 24 are provided with the protrusions 5 of each segment 60.

When a part of the heat insulating frame 42 is damaged, there is an advantage that it can be dealt with by replacing only the segment 60 at the damaged portion.

The mounting base 10 used to mount the refrigeration apparatus 12 to the freezer 14 can be used not only when the refrigeration apparatus 12 is mounted on the ceiling of the freezer 14 but also when the freezer 14 is mounted.
It can also be used when mounted on the side of a vehicle. In addition to the case where the heat insulating frame 42 is divided into four segments 60 as in another embodiment, the heat insulating frame 42 may be divided into two L-shaped segments.

[0013]

As described above, according to the refrigeration apparatus mounting frame structure of the present invention, since the projection having the sealing function is formed on the heat insulating frame, the sealing material as a separate member can be omitted. It is possible to reduce the number of parts and cost. Further, since the number of manufacturing steps is reduced, manufacturing efficiency can be improved. In addition, since the heat insulating frame does not fall off from the cooler mounting plate, the heat insulating frame does not come off from the mounting base during maintenance of a refrigerating device mounted in a freezer or the like, and a complicated mounting operation does not occur. In addition, in the structure in which the heat insulating frame is divided into a plurality of segments, even if a part of the heat insulating frame is damaged, it can be dealt with by replacing only the segment at the damaged portion, and the cost is reduced as compared with replacing the whole. It can be kept cheap. In addition, repairing a damaged portion of the heat insulating frame deteriorates the appearance, but replacing the segments does not reduce the overall appearance and has the advantage of maintaining high quality.
