Abstract

Disclosed herein are a washing machine that detects the weight of laundry based on the displacement of a rotary tub and a control method thereof. The washing machine includes a rotary tub displaced according to the weight of laundry, at least one sensor module to detect the displacement of the rotary tub, and a controller to calculate the weight of the laundry according to the displacement of the rotary tub. The weight of the laundry is sensed according to the displacement of the rotary tub in which the laundry is directly placed.

Description

technical field [0001] Embodiments of the present disclosure relate to a washing machine sensing the weight of laundry and a control method thereof. Background technique [0002] Generally, a washing machine includes: a water tub installed in a housing for receiving water containing detergent (ie, washing water); a rotary tub rotatably installed in the water tub for washing clothes; a door hingedly combined to the front of the case for opening and closing the opening formed in the front of the case. Laundry is put into the rotary tub through the opening of the housing, a predetermined amount of washing water is supplied into the water tub, and the rotary tub rotates to wash the laundry. [0003] When the user selects a washing course, the weight of the clothes is sensed to determine the amount of washing water, and according to the determined amount of washing water, washing water sufficient to wet the clothes is supplied to the tub together with detergent, and the rotating...
