Household electrical appliance and household electrical system

A household electric appliance comprising:

• a receiving unit that receives a request for a peak cut of power consumption at a predetermined rate from a remote controller and a mobile terminal;
• a drive unit that drives a power-consuming object to be driven;
• a control unit that controls an action of the drive unit;
• and
• a detecting unit that detects an electric current flowing through a predetermined electric current path within the appliance and transmits a detected electric current value to the control unit,
• wherein the control unit, in the case of reception of the peak cut request from the remote controller or the mobile terminal, controls the action of the drive unit to cut a maximum value of the power consumption within the appliance based on the requested rate to respond to the peak cut request,
• wherein the control unit compares the electric current value detected by the detecting unit and an electric current value set according to the predetermined rate requested by the remote controller or the mobile terminal and, if the electric current value detected by the detecting unit is greater than the electric current value set according to the predetermined rate, controls the drive unit to cut the maximum value of the power consumption within the appliance, according to the predetermined rate, and
• wherein the control unit, in the case of reception of the peak cut request from the remote controller or the mobile terminal, causes the number of rotations of a compressor driven by the drive unit to be decreased based on the requested rate.
