Abstract
Herein disclosed is a household electrical appliance easily to know whether electricity rates are high or low when using the household electrical appliance, even in the variable rate system. The household electrical appliance includes, a receiving unit that receives information of electricity rates which are changed based on power generation capacity and power consumption amount and charged for power consumption as instantaneous electricity rate information; an electricity rate information accumulating unit that accumulates the received instantaneous electricity rate information; a determination unit that outputs a result obtained by statistically calculating a plurality of the accumulated instantaneous electricity rate information items as reference electricity rate information, and compares the latest received instantaneous electricity rate information with the output reference electricity rate information; and a numerical value display unit that notifies whether the latest instantaneous electricity rate information is higher than the reference electricity rate information.
