Problems solved by technology

[0006] However, in this case, in order to fix the position of the vacuum insulation material without contacting the outer box and the inner box, it is necessary to provide a spacer, but when the polyurethane foam is foamed, the vacuum insulation material and the spacer are under pressure together. , so the fixed position may be offset by
If the fixed position of the vacuum insulation material is shifted, the gap between the vacuum insulation material and the outer box or inner box will be narrowed, and the flow path of the polyurethane foam will be blocked, resulting in an unfilled part of the polyurethane foam, which may increase the power consumption of the refrigerator.

Embodiment Construction

[0031] Hereinafter, the present invention will be described with reference to the illustrated embodiments.

[0032] figure 1 It is a schematic explanatory drawing at the time of pouring the polyurethane foam of the refrigerator which concerns on embodiment of this invention. figure 2 It is a schematic explanatory drawing of the polyurethane foam flow at the time of foaming the polyurethane foam of the refrigerator which concerns on embodiment of this invention. The refrigerator of the embodiment of the present invention such as figure 1 and figure 2 As shown, the box is integrally formed with an outer box 1 made of metal such as iron and an inner box 2 made of synthetic resin such as ABS ( image 3 ), install the enclosure with the door side facing down. The outer box 1 has side surfaces formed by side panels 12 , a rear surface formed by rear panels 13 , and a bottom surface formed by bottom panels 15 . When injecting polyurethane foam, make the back side of outer cas...

Abstract

The invention provides a refrigerator which can inhibit vacuum insulation material from bending and reduce the number of distance pieces. A vacuum insulation material (3) supported by a distance piece (60) and polyurethane foam (4) which is injected for foaming and filled in a manner of burying the vacuum insulation material (3) are disposed between an outer casing (1) and an inner casing (2). The distance piece (60) is formed by a rectangular wave-shaped plate (6). Top faces (6a) of protruding parts of the rectangular wave-shaped plate (6) are used as supporting parts of the vacuum insulation material (3), and bottom faces of recessed parts (6b) are used as abutting parts of the outer or inner casing. The top faces (6a) of protruding parts of the rectangular wave-shaped plate (6) are provided with extension parts (6d) extending in a regulated amount along the side direction.

Description

technical field [0001] The present invention relates to a refrigerator using a vacuum insulation material. Background technique [0002] In refrigerators in recent years, the demand for energy saving has increased, and the demand for space saving has also increased. Therefore, as means for fulfilling these needs, products using vacuum heat insulating materials whose heat insulating performance is significantly improved compared with rigid polyurethane foams have appeared. [0003] Such a refrigerator includes, for example, a refrigerator in which rigid polyurethane foam and a vacuum insulation material are provided between an outer box and an inner box, and the vacuum insulation material is directly bonded to the outer box with an adhesive. In the process of manufacturing the refrigerator by this method, since the sticking part is flat, the installation workability is good. In addition, a large area of ​​vacuum insulation material can be placed without being disturbed by u...
