Washing machine, power management apparatus and method of controlling the same

摘要

In a washing machine, a power management apparatus and a method of controlling the same, washing operation and drying operation commands are input by a user, power rate information for each time period is received from an EMS, a drying operation execution time is confirmed, and power rates corresponding to the drying operation execution time are determined based on the power rate information for each time period. Then, the power rates corresponding to the drying operation execution time are compared with the standard power rates to determine whether the power rates corresponding to the drying operation execution time are higher than the standard power rates, and an algorithm of a final spinning mode in the washing operation is adjusted if the power rates corresponding to the drying operation execution time are higher than the standard power rates.

主权项

1. A washing machine comprising:
a motor; a communication unit receiving power rate information for each time period from an energy management system (EMS); an input unit receiving an operation command from a user; and a controller determining the power rate of the predetermined time duration in a spinning cycle is higher than a standard power rate before finishing the spinning cycle when a washing operation command and a drying operation command are input, executing a first spinning cycle if the power rate is lower than the standard power rate, and executing a second spinning cycle if the power rate is higher than the standard power rate.
