Electrical equipment control device, electrical equipment control method and electrical equipment

An electrical equipment control method, comprising:

• a reception step of receiving desired time information indicating a desired operation start time or a desired operation termination time of an electrical equipment desired by a user, operation period information indicating a period required for operation by the electrical equipment, and electrical power information indicating an electrical power required for operation by the electrical equipment;
• a time-shift period setting step of setting a time-shift period indicating a period which has a time range including the desired time information received in the reception step and during which the operation start time or the operation termination time of the electrical equipment is shiftable;
• an electrical power charge information acquisition step of acquiring electrical power charge information indicating an electrical power charge that changes hour to hour;
• an operation time computing step of computing, based on the desired time information, the operation period information and the electrical power information received in the reception step and the electrical power charge information acquired in the electrical power charge information acquisition step, the operation start time or the operation termination time, on the basis of which the electricity charge that is billed when the electrical equipment is operated within the time-shift period set in the time-shift period setting step falls to or below a predetermined charge;
• and
• a transmission step of transmitting, to the electrical equipment, the operation start time or the operation termination time computed in the operation time computing step.

An electrical equipment, comprising:

• an input reception unit for receiving an input of desired time information indicating a desired operation start time or a desired operation termination time of an electrical equipment desired by a user;
• a transmission unit for transmitting the desired time information received by the input reception unit, operation period information indicating a period required for operation by the electrical equipment, and electrical power information indicating an electrical power required for operation by the electrical equipment;
• a reception unit for receiving the operation start time or the operation termination time transmitted from an electrical equipment control device which receives the desired time information, the operation period information and the electrical power information transmitted from the transmission unit, sets a time-shift period indicating a period which has a time range including the desired time information and during which the operation start time or the operation termination time of the electrical equipment is shiftable, and computes, based on the desired time information, the operation period information and the electrical power information and electrical power charge information indicating an electrical power charge that changes hour to hour, the operation start time or the operation termination time, on the basis of which the electricity charge that is billed when the electrical equipment is operated within the time-shift period falls to or below a predetermined charge;
• and
• an operation control unit for controlling an operation of the electrical equipment based on the operation start time or the operation termination time received by the reception unit.
