Experimental method：Side increases the uneven block of 0.5Kg on washing machine drum, and washing machine is then allowed not fill any clothes
The case where enter dehydration, drum velocity of rotation is up to 1200 RPM, then records X, Y, the data variation of Z axis, is as above tested
As a result, since drum is upper and lower（Z axis）, left and right（X-axis）There are bigger swing, therefore X on direction, Z axis data variation is very
Obviously, cut has apparent variation with the raising of rotating speed.
It is tested by two above, in conjunction with the data variation amplitude of 3-axis acceleration sensor, frequency, so that it may to judge to roll
The non-equilibrium state of bucket is based on cost consideration simultaneously as in actual use, can also use single-axis acceleration sensors,
Two axle acceleration sensors, but principle is consistent；Meanwhile it by three axis acceleration sensors, can also be installed not in washing machine
Usually prompt user corrects, and high vibration when avoiding using causes safety hazard, so that product is more reliable.
The present invention provides a kind of washing machine and unbalance detection of uneven detection, and the present invention is by detecting drum
Swing state, and do corresponding adjustment so that drum is in normal hunting range, reduces drum because of clothes amount, moisture
The bigger problem of the factors amplitude of fluctuation such as the cloth uniformity and drum rotating speed, moreover, washing machine can be reduced through the invention
Noise pollution.
