Washing machine and its detection method for unbalanced operation

Abstract

The invention provides a washing machine and a detecting method for unbalanced operation thereof, wherein the washing machine comprises a box body, a washing and dewatering cylinder, a detector and a controller. A suspension piece is arranged in the box body. The washing and dewatering cylinder is arranged in the box body through the suspension piece. The detector is used for detecting the distance between the box body and the washing and dewatering cylinder and the vibrational frequency of the box body, and the detector is arranged close to the inner side wall of the box body. The controller is connected with the detector, and when the washing machine conducts dewatering, judgment on whether the washing machine is at an unbalanced operation state or not is conducted through the controller according to the distance between the box body and the washing and dewatering cylinder and the vibrational frequency of the box body. According to the washing machine and the detecting method for unbalanced operation thereof, an electric component is adopted to judge whether the washing machine is at the unbalanced operation state or not, the judging precision is high, the reliability of the washing machine is high, the installation is convenient, installing deviation influence does not exist, and mechanical deformation and abrasion cannot be caused.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a washing machine and a detection method for unbalanced operation of the washing machine. Background technique [0002] Along with the raising of living standard, washing machine becomes the household appliance that people generally use. However, the washing machine often encounters the problem of unbalanced dehydration during the dehydration process. For example, because the clothes are on one side, the dehydration bucket does not run smoothly during dehydration, thus causing the dehydration bucket to hit the cabinet of the washing machine, resulting in greater vibration and noise, affecting normal use. In the prior art, a commonly used solution to the above-mentioned unbalanced dehydration problem is: judge whether the washing machine is unbalanced in dehydration by hitting the bucket switch, and adjust or alarm if the washing machine is in an unbalanced dehydrati...

AI Technical Summary

Problems solved by technology

However, there are many insurmountable problems in the above-mentioned scheme of judging dehydration imbalance by bumping the bucket switch, such as low judgment accuracy, poor reliability, misjudgment, switch failure, deformation and wear of mechanical parts, etc.
