Description

[Detailed description of the invention] The present invention relates to a heat insulating box for a refrigerator, etc., and has a structure in which the top surface of the heat insulating box is used as a table, and a simple structure for attaching a decorative frame to the end of the top surface, and a heat insulating material. To provide a heat insulating box body having a leakage prevention structure and a structure that allows easy installation of an upper hinge device of a door.

Embodiments of the present invention will be described in detail below based on the drawings.

Reference numeral 1 denotes a heat insulating box body in which a foamable synthetic resin such as polyurethane is filled as a heat insulating material 4 between an inner box 2 and an outer box 3 using an on-site foaming method.

Reference numeral 5 denotes small holes which are arranged two each at the left, right and rear ends of the upper wall 3A of the outer box 3 and penetrate through the upper wall 3A.

6 integrally includes the protrusion 7 inserted into the small hole 5 on the left side,
A square frame is formed on the back side of the right side and the back side of the upper wall 3A.
It is a decorative frame made of synthetic resin placed on the edge of the frame.

Reference numeral 8 denotes a hinge plate fixed from below with a screw 10 to one side of the front side of the decorative frame 6 that projects forward of the heat insulating body 1, for example, the back of the right side, and connects the rear part between the upper wall 3A and the decorative frame 6. A hinge shaft (8A) protrudes downward from the front.

Reference numeral 9 denotes a holder having a size such that when the projection 7 is inserted into the small hole 5, it is fitted onto the projection 7 in close contact with the lower surface of the upper wall 3A and covers the entire periphery of the small hole 5. By attaching the holder, the lower surface of the decorative frame 6 is held in close contact with the periphery of the small hole 5.

The holder 9 is made of a metal elastic plate or a synthetic resin elastic material and has a protrusion 7.
It is suitable to hold it by press-fitting it.

11 is a hinge device 1 whose lower part is attached to the front lower part of the box body 1
2, and the upper part is the hinge shaft of the hinge device) 8
A front opening 1A of a box body 1 is opened and closed by a door body pivoted at A.

With the present invention configured as described above, the decorative frame is positioned at a predetermined position by simple work on the earthen wall of the outer box, and in this state, the protrusion and the holder are fixed by filling the foam insulating material. The decorative frame is firmly fixed by being embedded in the heat insulating material, and in this case, the decorative frame is held tightly against the upper wall by a holder, so that the heat insulating material does not leak out from the small hole. It is.

Furthermore, the upper hinge device is configured to perform the foaming work of the insulation material while being attached to the back of the front part of the decorative frame in advance, compared to the conventional hinge device in which the hinge device was attached to the top surface of the insulation box. The assembly work is simplified, and since the decorative frame is firmly fixed in the foaming process, the hinge device is also firmly fixed.

In addition, the structure is optimal for using the earthen wall of the outer box directly as a table surface, and in the past, a decorative cover was attached to the hinge device, but this decorative cover can also be used as a decorative frame, eliminating the need for a separate decorative cover. It is what it is.
