PROBLEM TO BE SOLVED: To comprehensively manage information on temperature in a storage chamber of a refrigerator or consumed power of the refrigerator by remote control.SOLUTION: A temperature sensor portion 103, a power measuring portion 105, and a door opening time sampling circuit portion 108 obtain temperature measuring value information, power measuring value information, and door opening time measuring value information respectively. A command signal generating portion 204a generates a command signal for generating providing information to a refrigerator 100. A terminal side output portion 203 transmits the command signal to the refrigerator 100. A refrigerator side input portion 110 receives the command signal. A providing information generating portion 109a generates providing information on the basis of the command signal, by using the temperature measuring value information, the power measuring value information, and the door opening time measuring value information. A refrigerator side output portion 111 transmits the providing information to a terminal device 200. A terminal side input portion 202 receives the providing information. A terminal side information providing portion 205 provides the providing information received by the terminal side input portion 202. |
