Abstract

A device for a motor-driven appliance includes a communication unit, a date/time information acquisition unit, and a control unit. The communication unit performs communication with an external appliance having a date/time information indicating a current date and time. The date/time information acquisition unit acquires the date/time information from the external appliance via the communication unit. The control unit performs control based on the date/time information acquired by the date/time information acquisition unit.

Claims

1. A device for a motor-driven appliance comprising:

a communication unit that performs communication with an external appliance having a date/time information indicating a current date and time;

a date/time information acquisition unit that acquires the date/time information from the external appliance via the communication unit; and

a control unit that performs control based on the date/time information acquired by the date/time information acquisition unit.

2. The device for a motor-driven appliance according to claim 1, comprising a measurement unit that measures a current date and time,

wherein the control unit updates the current date and time measured by the measurement unit, based on the date/time information acquired by the date/time information acquisition unit.

3. The device for a motor-driven appliance according to claim 1, comprising a measurement unit that measures a current date and time,

wherein the control unit generates a difference information indicating a difference between the current date and time measured by the measurement unit and a date and time obtained from the date/time information acquired by the date/time information acquisition unit.

4. The device for a motor-driven appliance according to claim 1,

wherein, when the device for a motor-driven appliance is connected to other device for a motor-driven appliance, the control unit provides the date/time information acquired by the date/time information acquisition unit to the other device for a motor-driven appliance.

5. The device for a motor-driven appliance according to claim 1,

wherein the communication unit is communicatable with at least one of a UPS receiver, a standard radio wave receiver, a mobile communication terminal, and a personal computer as the external appliance.

6. The device for a motor-driven appliance according to claim 1, comprising a storage unit that stores a history of an operation of the device for a motor-driven appliance,

wherein the control unit associates a history information indicating the history of the operation with the date/time information, and stores the history information in the storage unit.

7. The device for a motor-driven appliance according to claim 6,

wherein the control unit counts a number of occurrences of the operation corresponding to the history information, and assigns the number of occurrences of the operation to the history information when storing the history information in the storage unit.
