Problems solved by technology

However, in most cases, when the clothes in the bucket are eccentric, the inner cylinder cannot hit the door switch due to the uncertainty of the movement trajectory of the inner cylinder, and the door switch fails, causing serious consequences such as the movement of the washing machine

Abstract

The present invention provides a washing machine, including: an inner cylinder, a motor, an acceleration sensor and a controller. The motor is used to drive the inner cylinder to rotate according to the preset dehydration cycle to complete the dehydration process; the acceleration sensor is used to detect the acceleration of the rotation of the inner cylinder according to the preset dehydration cycle; the controller is used to compare the acceleration during the dehydration process Acceleration and the size of the preset threshold to judge whether there is eccentricity. The washing machine of the present invention can accurately determine the load eccentric condition according to the acceleration detected in real time. The invention also proposes a method for judging the load eccentricity of the washing machine.

Description

technical field [0001] The invention relates to the technical field of washing machine manufacturing, in particular to a washing machine and a method for determining load eccentricity of the washing machine. Background technique [0002] At present, the method for judging the eccentricity of clothes in a wave-wheel washing machine is to install a door switch at a certain distance from the inner drum of the washing machine, and the door switch has a certain breaking stroke. When the clothes in the washing machine are entangled and have a large eccentricity, it will cause a large offset of the inner cylinder. If the offset reaches the breaking stroke of the door switch, the door switch will be broken, and the clothes will be shaken and dehydrated again. However, in most cases, when the clothes in the bucket are eccentric, the inner cylinder cannot hit the door switch due to the uncertainty of the inner cylinder's trajectory, and the door switch fails, causing serious consequen...
