Abstract

세탁기에서 입력 전원전압 변동을 감지하여 세탁기 최적의 수류패턴을 구현할 수 있도록 하는 세탁기의 전원 전압 제어방법을 제공한다.The present invention provides a method for controlling a power supply voltage of a washing machine to sense an input power voltage variation in a washing machine to implement an optimum water flow pattern of the washing machine.

이 전원전압 제어방법은 전원전압을 세탁기에 제공하는 방법에 있어서, 전원전압이 과전압인가를 판단하여 과전압이면 경보용 알람을 발생하고 전원 스위치를 오프시키는 제1단계와, 상기 전원전압이 과전압이 아니면 유저의 선택에 의해 세탁행정으로 진입하는 제2단계와, 상기 세탁행정 진입시 전원전압 변동에 따라 실동율을 변화시켜 세탁행정을 진행하는 제3단계를 포함하여 이루어진다.The power supply voltage control method is a method for providing a power supply voltage to a washing machine, comprising: a first step of determining whether the power supply voltage is an overvoltage and generating an alarm alarm if the overvoltage is an overvoltage; and if the power supply voltage is not an overvoltage, And a second step of entering the washing cycle by the user's selection, and a third step of changing the running rate according to the power supply voltage change when the washing stroke is entered.

따라서, 세탁기의 입력 전원전압 변동에 따라 실동율을 변화시켜 결정하므로 세탁성능을 향상 시킬수 있고, 세탁기에 위험 과전압이 인기되어 세탁기가 손상되는 것을 방지할 수 있는 효과가 있다.Therefore, it is possible to improve the washing performance by changing the actual operation rate according to the input power voltage variation of the washing machine, there is an effect that can prevent damage to the washing machine because the dangerous overvoltage is popular in the washing machine.
