Washing machine eccentricity detection method, machine-readable storage medium and frequency conversion washing machine

Abstract

The embodiment of the invention provides a washing machine eccentricity detecting method, a machine-readable storage medium and a variable frequency washing machine, and belongs to the field of household appliances control. The method includes the steps that when an inner barrel of the washing machine rotates, the linear acceleration of a preset point on the inner barrel is periodically detected according to the preset rotation angle; the maximum value and the minimum value of the linear acceleration of the preset point in the process that the inner barrel rotates by a round; the real-time eccentricity is calculated according to the maximum value and the minimum value as well as the linear acceleration of the preset point in the process that the inner barrel rotates by a round. By means of the technical scheme, the linear acceleration of the preset point on the inner barrel is periodically detected, the real-time eccentricity is calculated according to the maximum value and the minimum value as well as the linear acceleration of the preset point in the process that the inner barrel rotates by a round, namely the eccentricity can be evaluated quantitatively, and eccentricity is detected dynamically in real time.

Description

technical field [0001] The invention relates to control optimization of home appliances, in particular to a washing machine eccentricity detection method, a machine-readable storage medium and a frequency conversion washing machine. Background technique [0002] The washing machine is a device that uses the action of washing water and detergent to remove the dirt stuck in the laundry through steps such as washing, cleaning, dehydration, and drying. When the washing machine is washing, the inner wall of the stainless steel bucket rubs or beats the clothes continuously, and then realizes the washing of the clothes; when dehydrating, driven by the motor, the whole inner bucket of the washing machine rotates, and the moisture contained in the clothes is under the action of centrifugal force. The clothes are separated from the inner tub of the washing machine through the dehydration holes on the inner tub of the washing machine, and then the water is discharged out of the washing...

AI Technical Summary

Problems solved by technology

[0003] During the use of the washing machine, due to the inconsistent water absorption capacity and material of the laundry, the problem of uneven distribution of the laundry is prone to occur

Uneven distribution of laundry will cause the rotation axis of the inner tub of the washing machine to deviate from the preset direction, causing the washing machine to run in an eccentric state

Excessive eccentricity will cause the inner barrel to hit the box or the control rod, and even produce strong vibration and noise when drying at high speed

Severe eccentricity can even cause problems such as shifting, jumping or damage to the washing machine

[0004] In the process of implementing the present invention, the inventors of the present application found that the eccentric sensing scheme of the washing machine in the prior art has the defects that the eccentric sensing is relatively large, the speed range is narrow, and the running state of the load cannot be monitored all the time.
