Abstract
The present invention relates to a method for controlling a laundry machine, comprising a cloth sensing step of sensing the cloth of laundry, wherein the cloth sensing step comprises: a weight sensing step of sensing the weight of the laundry; a photographing step of photographing the inside of a drum; a volume sensing step of sensing the volume of the laundry inside the drum by mean of the captured image; and a density calculation step of calculating the density of the laundry on the basis of the sensed volume and weight.
Claims19
A method of controlling a washing machine, the method comprising:
- detecting properties of laundry;
- wherein the detecting the properties of the laundry comprises:
- detecting a weight of the laundry;
- capturing an image of an interior of a drum;
- detecting a volume of the laundry in the drum using the captured image;
- and
- calculating a density of the laundry based on the detected volume and the detected weight.
A washing machine comprising:
- a cabinet;
- a tub installed in the cabinet to contain wash water therein, the tub having an entrance formed in a front side thereof;
- a drum rotatably installed in the tub to contain laundry therein, the drum having through-holes formed in a cylindrical-shaped side surface thereof;
- a motor for rotating the drum;
- a camera installed in the entrance to capture an image of an interior of the drum;
- and
- a controller for calculating a density of the laundry contained in the drum by measuring a volume and a weight of the laundry based on the image captured by the camera and a load of a driving unit.
