In FIGS. 5 and 6, reference numeral 1 denotes a heat insulating box body 36.
This is a cooling storage with a heat insulating structure having a heat insulating opening / closing door 2 in the front opening, and a rectangular opening 4 is formed in the top wall 3 of the heat insulating box 36. An outer panel 9 made of a steel plate as an outer plate and an inner sheet 1 of a resin molded product made of polypropylene or the like as an inner plate are provided on the ceiling wall 3 in which the opening 4 is formed.
0, a molded heat insulating material 16 of a rigid synthetic resin molded product such as expanded polystyrene inserted between the outer panel 9 and the inner sheet 10 and a space defined by the outer panel 9, the inner sheet 10 and the molded heat insulating material 16. Refrigerator mounting base 12 made of foamed polyurethane insulation 11
Is detachably attached.

1 to 4, through holes 5 and 5 are formed in the outer panel 9 of the mounting base 12, and through holes are also formed in the inner sheet 10 at positions facing the through holes 5 and 5. 6, 6
Has been drilled. Further, a reinforcing plate 7 for mounting a cooler 23, which will be described later, is arranged on the inner surface side of the inner sheet 10, and through holes 8 and 8 are also formed at positions corresponding to the through holes 6 and 6 of the reinforcing plate 7. It is set up. The molded heat insulating material 16 has a predetermined elasticity and has a substantially rectangular shape.
Protrusions 13, 13, 14, 14 having an outer shape substantially the same as the inner diameter of each of the through holes 5, 6 are integrally formed at positions corresponding to the through holes 5, 5, 6 and 6 of A, 16B. ing. The outer surface (upper surface) of the outer panel 9 and the outer surface (lower surface) of the inner sheet 10
The sides are communicated with each other by through-hole portions 15 and 15 which are opened vertically in the protrusions 13 and 14.

Next, a procedure for assembling the mounting base 12 will be described. The reinforcing plate 7 is arranged on the inner surface of the inner sheet 10 so as to correspond to the through holes 6 and 6. A molded heat insulating material 16 is sandwiched between the outer panel 9 and the reinforcing plate 7 to form the inner sheet 1.
0 and the outer panel 9 are polymerized. At this time, the upper end surface 16A
The projections 13 and 13 of the lower panel 16B are inserted and engaged with the through holes 5 and 5 of the outer panel 9 to project upward, and the projections 14 and 14 of the lower end surface 16B are the through holes 8 and 8 of the reinforcing plate 7 and the inner sheet. The through holes 6, 6 of 10 are inserted and engaged with each other to project downward.
As a result, the molded heat insulating material 16 is positioned on the outer panel 9 and the inner sheet 10 at the same time, and the upper and lower end surfaces 16A and 16B of the molded heat insulating material 16 have the through holes 5 and 5 around the inner surface of the outer panel 9 and the through hole 8, respectively. 8 It closely contacts the inner surface of the reinforcing plate 7 around it.

When the combination is set between the upper and lower foaming jigs 19 and 17, the protrusions 13 and 14 are crushed by the upper and lower jigs 19 and 17 in the direction of the through holes 15 and 15 as shown in FIG. It deforms and comes into close contact with the end faces of the through holes 5, 6 and 8. In this state, the polyurethane foam stock solution is injected into the space defined by the outer panel 9, the inner sheet 10 and the molded heat insulating material 16 to fill the heat insulating material 11 by the in-situ foaming method. At this time, the upper and lower end surfaces 16A and 16B of the molded heat insulating material 16 are in close contact with the inner surfaces of the outer panel 9 and the inner sheet 10 around the through holes 5 and 6, and the protrusions 13 and 14 are formed on the end surfaces of the through holes 5, 6, and 8. Since it closely contacts the tools 19 and 17, the leakage of the heat insulating material 11 from the through holes 5, 5, 6, and 6 does not occur. That is, the protrusions 13 and 14 serve as a sealing material. Further, in the embodiment, the molded heat insulating material 16 has a through hole portion 15,
15 are formed at two places, these through hole portions 15,
Since 15 is formed in a single block, the wall thickness around the through-hole portion 15 can be increased, and the heat insulating material 11 can be prevented from being crushed by the foaming pressure. Conventionally, since the through holes are formed in each of the heat insulating material blocks, there is a problem that the wall thickness around the through holes becomes thin and the heat insulating material is crushed by the foaming pressure of the heat insulating material, but this is also prevented in the embodiment.

The electric compressor 20, the condenser 21, and the condenser cooling blower 22 constituting the condensing unit of the refrigerating apparatus are mounted and mounted on the outer panel 9 of the mounting frame 12 thus constructed. The inner seat 10 of the mounting base 12 has a cooler 23 that constitutes a cooling unit.
7, the condenser 21 and the cooler 24 are connected via a pressure reducing device (not shown) through the high-pressure refrigerant pipe 30 inserted into one of the through holes 15, and the accumulator 31 on the outlet side of the cooler 23 is connected. The electric compressor 20 is also connected by a low-pressure refrigerant pipe 32 which is also inserted through the one through hole portion 15. Both refrigerant pipes 30 and 32 are heat insulating material tubes 3 respectively.
However, since the protrusions 13 and 14 of the molded heat insulating material 16 project from the through holes 5 and 6, the heat insulating material tubes 34 and 34 or the pipes 30 and 32 of the edges of the through holes 5 and 6 are covered. Damage is prevented. Further, a lead wire 35 for feeding or controlling is inserted into the other through hole portion 15, but the lead wire 35 is also prevented from being damaged by the edges of the through holes 5 and 6 by the protrusion portions 13 and 14. That is, the protrusions 13 and 14 serve as a conventional bushing.

The mounting base 12 and the ceiling wall 3 assembled as described above are connected via a sealing material 18, the opening 4 is closed by the mounting base 12, and the mounting base 12 is fixed to the ceiling wall 3 by bolts. Further, the front end of the unit cover 24 is fixed to the inner surface of the top wall 3 and the rear end is fixed to the inner surface of the rear wall, and the cool air circulation fan 25 is attached to the unit cover 24. The unit cover 24 facing the cold air circulation fan 25 has a suction port 26 in the front part and a blowout port 27 in the rear part.
The cold air that has respectively been formed and is cooled by the cooler 23 is circulated in the refrigerator to be cooled.

[0016]

According to the mounting frame for the refrigerating apparatus of the present invention,
Since the protrusions of the molded heat insulating material serve as a heat insulating material foam leakage preventing member and a damage preventing member such as a pipe, the number of parts can be remarkably reduced as compared with the conventional case. In addition, the projection also plays a role of positioning the molded heat insulating material, and as a whole, the workability of assembling the mounting base can be significantly improved.
