PROBLEM TO BE SOLVED: To use a thermochromic member for verifying the inside temperature of a refrigerator by providing a heat transfer means that functions as the heat transfer passage between the thermochromic member being placed on the outer surface of the refrigerator and the inner air of the refrigerator. SOLUTION: A thermochromic member 22 being fixed onto the inner surface of a temperature insulation plate 21 consists of a thermally sensitive discoloration substance where color changes when the substance is exposed to a specific range of temperature. A pipe member 23 functions as a heat transfer passage where the inner chill of a refrigerator 10 can reach the thermochromic member 22 and is inserted into a through hole 24 of a door member 11. When the pipe member 23 is inserted into the through hole 24, one end of the pipe member 23 projects outside the door member 11 and is exposed to the inner air of the refrigerator 10. On the other hand, the other end is brought into contact with the thermochromic member 22. Then, the inside chill of the refrigerator 10 is transferred to the thermochromic member 22 via a duct being formed by the pipe member 23, and the thermochromic member 22 is allowed to react according to change in the temperature of the chill. |
