Washing machine eccentricity detection method

Abstract

The invention belongs to the field of washing machines, and particularly discloses a washing machine eccentricity detection method, including starting a dehydration spinning program, judging whether the eccentricity of an outer tub rotating at the current rotation speed is greater than or smaller than the impact eccentricity value when an acceleration sensor detects that the eccentricity value ofthe outer tub rotating at the current rotation speed is greater than the limit eccentricity value; if the eccentricity of the outer tub running at the current rotation speed is greater than the impacteccentricity, then determining whether to perform eccentricity correction or not; if the eccentricity of the outer tub running at the current rotation speed is smaller than the impact eccentricity, then judging whether to continue to spin or not. By the eccentricity detection method, regulation of the eccentricity not enough to cause tub impact or the accidental eccentricity can be reduced, spinning time for dehydration can be shortened, and washing efficiency can be improved.

Description

Technical field [0001] The invention belongs to the field of washing machines, and specifically relates to a method for detecting eccentricity of washing machines. Background technique [0002] During the use of the washing machine, due to the inconsistency of the 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 washing machine to deviate from the center position. When the washing machine is running in an eccentric state, the outer tub will hit the box or the control rod, causing vibration or noise. When the eccentricity is serious, the washing machine may even move, jump or damage problem. [0003] Chinese patent 201410266859.7 proposes a washing machine imbalance detection method, including the following steps: run the dehydration sequence, execute the eccentric amount detection test dehydration action; the sensor module executes the eccen...

Problems solved by technology

[0004] Although the above methods can accurately judge the eccentricity and deal with it in a timely manner, within a certain range, even if the eccentricity occurs, there may not necessarily be a bucket collision. If the washing machine detects the eccentricity and corrects the eccentricity, it will seriously affect the laundry. Efficiency, and multiple eccentric adjustments will also affect the service life of the washing machine
