Washing machine and control method thereof

Abstract

The present invention relates to a washing machine and a control method thereof. For the laundry put into the washing machine, the amount of the laundry is measured by using the gravity and inertia that play a role in the operation of the motor, thereby accurately calculating the amount of the laundry. In addition, the influence of the initial position of the laundry and the flow of the laundry can be minimized, and the amount of the laundry can be measured using the current value of the running motor regardless of the sensorless characteristic. In addition, the accuracy of the amount of laundry can be improved, and the amount of laundry can be judged in a short time, so it is easy to enter the dehydration operation, and the washing time can be shortened, thereby saving energy.

Description

technical field [0001] The invention relates to a washing machine and a control method thereof, in particular to a washing machine for detecting the amount of laundry put into the washing machine and a control method thereof. Background technique [0002] In general, a washing machine is a device that processes laundry through various operations such as washing, dehydrating, and / or drying. [0003] The washing machine supplies a prescribed amount of wash water to a drum containing laundry, dissolves an appropriate amount of detergent in the wash water, thereby removing stains attached to the laundry by chemical action with the detergent, and, following The washing tank with the laundry rotates, and the washing water and the laundry generate mechanical friction or vibration, thereby easily removing contaminants from the laundry. [0004] The washing machine executes a washing course, a rinsing course, and a dehydration course as processes for controlling contamination of lau...
