Problems solved by technology

For example, the rotation speed is affected by physical factors (such as windage loss due to rotation of the motor, frictional resistance of bearings, contact resistance of clothing, and mechanical vibration) and electrical factors (such as detection error of rotation speed and fluctuation of power voltage) , resulting in laundry weight detection errors and the inability to detect precise laundry weights

Abstract

A method of detecting weight of laundry contained in a washing machine (1). A calibration mode is provided that is performed separately from a washing mode such that a detection error of the weight of laundry, which occurs due to external environment factors, is calibrated when the weight of laundry is detected using a motor (15). The calibration mode is provided to find the weight detection offset data of the washing machine based on external environment factors, and to store the weight detection offset data found. When the weight of laundry is detected in a next washing mode, the weight of laundry is calibrated by use of the weight detection offset data of the washing machine, so that the weight of laundry accommodated in the washing machine is precisely detected.

Description

technical field [0001] Embodiments of the present invention relate to a washing machine and a method for detecting the weight of laundry contained in the washing machine. Background technique [0002] A washing machine (referred to as a drum washing machine) includes: a tub containing water (washing water or rinsing water); a drum rotatably installed inside the tub to hold laundry; and a motor generating driving force to rotate the drum. As the cylindrical drum rotates, laundry accommodated in the drum is lifted and lowered along an inner wall of the drum, thereby washing the laundry. [0003] Such a washing machine performs washing by performing a series of operations including: a washing cycle for removing dirt from laundry by using water (specifically, washing water) in which detergent is dissolved; For rinsing off soap scum or residual detergent from laundry by using water not containing detergent (in particular, rinsing water); a spin-dry cycle, configured to spin-dry ...
