Abstract

The invention discloses a washing machine and controlling method, which is characterized by the following: the washing machine contains motor to rotate washing barrel to wash cloths, motor driving part, rotary speed sensing part to judge the movement is right or not, display part to display the judged movement, microprocessor to judge whether the dehydrating course is normal or not and make display part display error. The invention improves working efficiency, which avoids temporary error movement due to ill drainage reason.

Description

technical field [0001] The present invention relates to a washing machine and its controlling method (Washing machine and it's controlling method), in particular, to a washing machine controlling method for sensing the rotation speed of a motor, stopping the dehydration operation when the motor rotation speed is too low, and effectively re-dehydrating. Background technique [0002] A washing machine is a device that removes contaminants from clothing. It uses the chemical action of the detergent to remove the pollutants on the clothes by soaking the clothes in the washing water with an appropriate amount of detergent, and makes friction or impact between the washing water and the clothes by rotating the washing tub containing the clothes , making it easier for pollutants to escape from clothing. [0003] Such as figure 1 As shown, a traditional washing machine includes a washing tub for holding clothes, a motor for rotating the washing tub, and a microprocessor for adjusti...
