<p><P>PROBLEM TO BE SOLVED: To provide a refrigerator capable of easily determining states of deterioration or failure of a vacuum heat insulating material in order to solve a problem that although some of conventionally proposed refrigerators detect internal pressure of vacuum heat insulating materials and display the internal pressure on pressure display parts, these refrigerators only detect the internal pressure and display it on the pressure display parts and do not fulfill a function to diagnose deterioration or failure. <P>SOLUTION: Deterioration or failure of the vacuum heat insulating material 15a is diagnosed from change in detected temperature by a temperature sensor 38 detecting surface temperature of the vacuum heat insulating material 15a, and the diagnosis result is displayed on a display part. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
