Abstract:
A method for warning of an abnormal water supply in a washing machine having cool and hot water supply valves for respectively supplying hot and cool water, said method comprising the steps of:detecting a temperature of ambient air of a water supply port of the washing machine before at least one of the cool and hot water supply valves of the washing machine is opened;detecting a temperature of water being supplied to the washing machine when at least one of the cool and hot water supply valves is opened;determining whether each of the respective cool and hot water supply valves is opened or closed;comparing the detected temperature of ambient air with the detected temperature of water;giving an alarm of an abnormal water supply when the detected temperature of ambient air and the detected temperature of water are identical to each other for a predetermined time;identifying a temperature type of water being supplied according to the detected temperature of the water;determining whether the water is normally or abnormally supplied by comparing the determined opened cool and/or hot water supply valves with the temperature type of water identified; andgiving an alarm of an abnormal water supply when the water is determined in said determining step to be abnormally supplied.
