Method for detecting dehydration imbalance of inclined drum washing machine

Abstract

The invention discloses a method for detecting dehydration imbalance of an inclined drum washing machine, which comprises the steps of (1) carrying out eccentricity detection on an inner barrel and judging whether the eccentricity exceeds the predetermined low-speed eccentricity when the rotational speed of the inner barrel achieves the low-speed detection speed, carrying out eccentricity correction when the judgment result is yes, otherwise, continuously detecting the eccentricity; and (2) carrying out the eccentricity detection on the inner barrel and judging whether the eccentricity exceeds the predetermined high-speed eccentricity when the rotational speed of the inner barrel achieves the high-speed detection speed, carrying out the eccentricity correction when the judgment result is yes, otherwise, entering into the high-speed dehydration. The method is divided into two detection stages of low-speed detection speed and high-speed detection speed, and the adoption of the unbalanced detection on a two-stage speed platform can accurately distinguish the eccentricity position and the eccentricity of clothes and adopt the different dehydration control methods and eccentricity correction strategies according to the eccentricity situations, thereby achieving the fast eccentricity correction and the smooth and high-efficient dehydration effect.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a method for detecting unbalanced dehydration of inclined-drum washing machines. technical background [0002] In the washing machine control technology, one of the most critical control processes is the detection of the vibration generated by high-speed dehydration and the eccentricity of the clothes. The inclined drum washing machine is different from the front-loading drum washing machine. The horizontal plane forms a certain angle, and the influence of the eccentric unbalance of the clothes in the inner drum on the system is different from that of the traditional front-loading drum washing machine. Therefore, special detection and control methods must be adopted according to the characteristics of the system structure. [0003] The existing dehydration imbalance detection method is: during low-speed dehydration, detect the amount of eccentricity, determine the highes...

AI Technical Summary

Problems solved by technology

In an inclined-drum washing machine that uses a series-excited motor as the driving motor, since the front and rear positions of the eccentricity of the clothes are different, the impact on the subsequent dehydration is also different, and the eccentricity detection effect at a single speed is not ideal
