C) Problems to be Solved by the Invention In the first and second prior art described above, there is a problem in which the temperature inside the refrigerator is much lower than the temperature outside the refrigerator during operation of the low-temperature refrigerator. A large compression pressure acts on the inner door panel and the insulating wall on the inner side of the door, while the outer panel of the door and the insulating wall on the outer door try to maintain a normal state. The problem with the door is that it warps until the two are balanced.

In addition, if a metal plate is used for the outer door panel and the inner door panel is made of resin, when the foam insulation material cools down to room temperature during the manufacture of the insulated door, the shrinkage rate of the inner panel is greater than that of the outer door panel. For insulation! There was a problem that warping occurred in 10%. and,
In order to avoid the above-mentioned problems, when reinforcing members are provided, the number of components of the heat-insulating door increases due to the plurality of reinforcing members, and the work time for installing the reinforcing members becomes longer. was. Furthermore, the thin film of the third prior art is for protecting the inner box from the Freon gas in the foam insulation material, and when the thin film is provided on substantially the entire side surface of the insulation material of the inner box, the inner box and the insulation material Because there is no adhesion with
Lifting of the inner box from the heat insulating material or bending of the inner box occurred. The present invention aims to solve the above problems.

(e) Function The foamed heat insulating material filled in the space formed by the inner shell and the outer shell is not bonded to both sides of the inner shell, and the inner thigh and the outer shell are not fixed. When the foamed heat insulating material is cooled after being filled, when the inner shell made of a resin with a high shrinkage rate shrinks more than the outer shell whose front surface is made of a metal with a small shrinkage rate, the inner shell shrinks freely without being restricted by the insulation material on both sides of the insulation door and the outer shell.
Also, is an adhesive surface bonded to a heat insulating material provided between the non-adhesive surfaces on both sides of the inner shell? By adhering the inner shell and the heat insulating material at this adhesive surface, lifting, stickiness, etc. of the inner shell can be avoided.

Thereafter, when the insulation material (8) gradually cools down, the inner plate (6) contracts more toward the center than the outer plate (4). However, when the disk (6) contracts, both sides of the inner plate (6) are covered with heat insulating material (
Slippage occurs between the surface of the insulation material (8) and the inner plate (6) (11), (120).
) is inserted into the gasket f13 and is not fixed, so the disc (6) is not restrained by the insulation material (8) and moves toward the center as shown by the arrow in Figure 1. I turn and shrink. Also, when the heat insulation door (1) is attached to the low-temperature refrigerator body (21K) and the low-temperature refrigerator is operated for cooling; the inner plate (6) shrinks further, but the surface of the sea H1l (1) and the insulation material ( 8
), and due to the non-fixed state of the gasket αJ and the inner plate (6), the inner plate (6) contracts without being restrained. Note that (0 in FIG. 6 is the collapsing surface between the heat insulating material (8) and the sheet (121).

Therefore, during cooling operation after filling the heat insulating door ill with the heat insulating material (8) and after installing the heat insulating door (1) to the low-temperature refrigerator body (2),
When the shrinkage rate of the inner plate (6) is larger than that of the outer plate (4), the sheet αl) on both sides of the inner plate (6), the sliding between the side surfaces of the heat insulating material of tta and the heat insulating material (8), and the inner As the inner plate (6) cools, the insulation material (
8) Do not be restrained (shrink towards the center, heat insulating material t8
1 will not be pulled by the disc (6), and therefore the warping in the longitudinal direction of the insulation jllll+, which conventionally occurs when the inner plate (6) contracts, can be avoided without providing a reinforcing member. Also, since the surface of the inner plate (6) between the sheet (Ill and sheet 02) is bonded to the heat insulating material (8), it is possible to prevent the disc (6) from floating or bending.
As a result, the quality of the heat insulating door (1) can be significantly improved.

g) Effect Since the present invention is a heat insulating door as described in the above embodiment, non-adhesive surfaces are provided on the sides of the heat insulating material on both sides of the inner shell,
Furthermore, since the periphery of the inner shell is not fixed, when the shrinkage rate of the inner shell is greater than the shrinkage rate of the outer shell during manufacturing of the insulated door or during operation of the low-temperature refrigerator after the insulated door is installed, the inner shell The insulation material will not contract independently of the insulation material and be pulled by the inner shell, and warping of the insulation door can be avoided with a simple structure without providing any reinforcing members. Since the side surface of the heat insulating material of the inner shell in between is bonded to the heat insulating material, lifting or bending of the inner shell can be prevented, and the quality of the heat insulating door can be significantly improved.
