A household electric appliance and a household electric system are provided which are capable of quickly responding to the electric power demand in which the peak cut of the power consumption is requested. The household electric appliance comprises: 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; and a control unit that controls an action of the drive unit. 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 so as to cut a maximum value of the power consumption within the appliance based on the requested rate.

Provide are a household electric appliance, household electric system and server apparatus that perform operation start or stop at reserved set times and that are convenient with regard to reserving operation. A household electric appliance capable of a reserved operation of performing an operation start or stop at a set time comprises: a receiving unit that receives a setting signal indicative of an operation start time in the reserved operation of the household electric appliance from each of a remote controller and a mobile terminal; a storage unit that stores the setting signal; and a control unit that controls operation of the household electric appliance. The control unit, in the case of overlapping of an operation time zone defined by the setting signal from the remote controller and the operation time zone defined by the setting signal from the mobile terminal, selects the earlier time and performs the operation start.

A fan drive device is not affected by variations in the strength of the fan drive motor rotor magnet or the components of the circuit for detecting fan drive motor induction voltage, or by the capacitance of a high capacitance capacitor in a dc supply circuit, and can therefore detect with good precision and without added components the speed of a high voltage, PWM drive fan drive motor when driven by an external force such as the wind. The fan drive device detects fan drive motor speed using a plurality of signals obtained from Hall ICs disposed in the fan drive motor for detecting the rotor magnet position, and prohibits fan drive motor drive when the fan drive motor speed is detected to exceed a specific threshold value.
