Home electric appliance

Abstract

A home electric appliance of the present invention comprises: an input operation unit for inputting desired time information indicating desired operation start time or desired operation end time; a receiving unit for receiving a time shift calculation result including operation start time or operation end time that makes an electricity rate less than or equal to a predetermined rate, the electricity rate being charged when the home electric appliance is operated within a period determined by the desired time information, and also including the electricity rate charged at the operation start time or the operation end time; a storage unit for storing a reference value used for evaluating the time shift calculation result; a comparison evaluating unit for performing comparison processing for comparing the time shift calculation result with the reference value stored in the storage unit; an operation control unit for controlling the operation on the basis of the time shift calculation result; and a display unit for displaying the information about the operation. The display unit changes a display mode according to the comparison result by the comparison evaluating unit.

Description

technical field [0001] The present invention relates to a household electrical appliance that controls an operation start time or an operation end time. Background technique [0002] Conventionally, there has been proposed a power load leveling system that prompts each consumer to use electric power during the time period of the day when the load on the power supply device of the power company is low (for example, refer to Patent Document 1). [0003] In the power load leveling system described above, by presenting to each consumer a time period (recommended power usage time) of a day when the load of the power supply device is low, the use of electric power during the time period is promoted, and the low-peak power of power demand can be increased. . In addition, at the same time, it is also desirable to reduce the peak power of the power demand and to average the load of the power supply device as a whole. [0004] In addition, by leveling the load of the power supply de...

Problems solved by technology

For example, in the case of operating a home appliance during a time when electricity is cheap, the user feels dissatisfied that the home appliance is not operated at the desired time, and the clothes are easily wrinkled because the clothes are dried earlier than the appropriate time. High dissatisfaction with the results

Conversely, there are cases where the electricity price is higher than normal because the home appliances are prioritized to be operated at the user's desired time, and clothes are dried at a time when clothes are not easily wrinkled.
