Claims

[Scope of utility model registration request]

a temperature sensor for detecting the temperature inside the refrigerator; a means for sequentially sampling temperature information detected by the temperature sensor; a memory for storing a predetermined number of sampling temperature information of the detected temperature information sampled by the means; control means for the memory for sequentially updating older information among the predetermined number of stored sampling temperature information with new sampling temperature information obtained by the sequential sampling; The apparatus is equipped with an arithmetic circuit that obtains average temperature information by averaging the information for each predetermined number of sampled temperature information, and a display that displays the average temperature information as a temperature value of the food stored in the refrigerator. Features a temperature display device for food inside the refrigerator.
