A washing machine dehydration method, apparatus and washing machine, the method comprising: step 1: detecting a current eccentricity value to serve as a first eccentricity value, and determining a first dehydration rotation speed value corresponding to the first eccentricity value; step 2: performing a corresponding dehydration operation according to a result of a comparison between the first dehydration rotation speed value and a preset rotation speed value; step 3: detecting a current eccentricity value to serve as a second eccentricity value, and determining a second dehydration rotation speed value corresponding to the second eccentricity value; step 4: performing a corresponding dehydration operation according to a result of a comparison between the second dehydration rotation speed value and the preset rotation speed value if the second eccentricity value is less than the first eccentricity value, assigning the value of the second eccentricity value to the first eccentricity value, and then performing s
