Abstract (en)
[origin: US2012279261A1] A washing machine that senses whether a door is opened or closed, vibration of a washing tub or weight of the washing tub. The washing machine includes an optical sensor mounted at a predetermined position in the washing machine and a controller to analyze an output value of the optical sensor to determine whether a door is opened or closed, vibration of a washing tub or weight of the washing tub. Whether the door is opened or closed, vibration of the washing tub or weight of the washing tub may be determined using a single infrared sensor in a noncontact manner.
