Problems solved by technology

[0011] However, the areas S100 , S200 where the foam insulation 140 , 240 is bonded to the outer panels 110 , 210 are relatively small compared to the insulation doors 100 , 200 of conventional refrigerators and the insulation doors described in Patent Documents 1 and 2.
Therefore, the insulation doors 100, 200 have a problem that the foam insulation 140, 240 covering the vacuum insulation 150, 250 cannot be firmly bonded to the back surface of the outer panel 110, 210.
[0012] According to this situation, even if the outer panels 110, 210 are fixed to the insulation doors 100, 200 by the foam insulation 140, 240 and the double-sided tape 160, 260, since the foam insulation 140, 240 has weak adhesive force, the There are also concerns about divestitures from the hottest 100, 200

Abstract

The present invention provides a refrigerator which is capable of the foamed heat-insulating member is securely affixed to the outer plate of the refrigerator (1) arranged on the insulated door (2A) a surface of the outer plate made of glass is arranged on the outer plate (10), (10) the periphery of the door frame (20) is arranged on the outer plate (10) of the back side of the vacuum heat-insulating material (30) to sandwich a vacuum heat-insulating material (30) is filled in by the outer plate (10) the space formed by the door frame (20) and a foamed heat-insulating member (40) (50) arranged in the door frame; and (20) the inner plate (60). a vacuum heat-insulating material (30) the outer plate (10) is formed, the side length (l2) (60) side than the inner plate length (L1).

Description

technical field [0001] The present invention relates to a refrigerator having an insulating door provided with a glass outer panel provided on the surface of the door and a vacuum insulation material provided inside the door. Background technique [0002] As a door of a refrigerator, in order to improve glossiness, the refrigerator which provided the outer panel made of glass on the surface of a door is known (for example, refer patent document 1 and patent document 2). In the doors of the refrigerators described in Patent Documents 1 and 2, in order to realize energy saving and space saving, a vacuum heat insulating material and a foam heat insulating material excellent in heat insulating properties are built in to constitute an insulating door. [0003] Figure 9 It is a transverse cross-sectional view showing the structure of a rotary door of a conventional refrigerator. Figure 10 It is an exploded perspective view showing the structure of the drawer type door of the co...
