摘要： PROBLEM TO BE SOLVED: To provide a refrigerator provided with spacers and supporting members between a vacuum heat insulating material, and an outer box and an inner box causing no separation of the vacuum heat insulating material by the foaming pressure of urethane foam, and further leaving no urethane foam-uncharged part. SOLUTION: By making adhesion faces with the vacuum heat insulating material 50e and the outer box 21e of the spacer 70 continuous plane faces when disposing the vacuum heat insulating material 50e, an adhesion area can be increased, and the adhesion force of the spacer 70 and the vacuum heat insulating material 50e and the outer box 21e can be increased. Since the adhesion faces are the continuous plane faces, adhesive agent coating work and attaching work can be easily performed. Furthermore, since the supporting members 80 are disposed at an inner box side, or a face at an inner box side of the vacuum heat insulating material, the vacuum heat insulating material 50e is sandwiched by the spacer 70 and the supporting members 80, and thus the separation of the vacuum heat insulating material 50e by the foaming pressure can be prevented.

摘要翻译：要解决的问题：为了提供一种在真空绝热材料和外箱和内箱之间设置有间隔件和支撑构件的冰箱，由于聚氨酯泡沫的发泡压力不会使真空绝热材料分离，并且进一步不留下聚氨酯泡沫不带电部分。解决方案：当设置真空绝热材料50e时，通过使真空绝热材料50e和间隔件70的外部箱体21e连续平面的粘合面，可以增加粘合面积，并且粘附力间隔件70和真空隔热材料50e和外箱21e可以增加。由于粘合面是连续的平面，因此可以容易地进行粘合剂涂布和附着工作。此外，由于支撑构件80设置在真空绝热材料的内侧箱体或内箱侧的面上，所以真空绝热材料50e被间隔件70和支撑构件80夹在中间，因此可以防止真空隔热材料50e由发泡压力的分离。版权所有（C）2011，JPO＆INPIT
