S2: if dehydrating inner drum smooth running in S1 step test process, the central shaft of degree of will deviate from test device is fixed on laundry
The center of impeller in machine dehydrating inner drum, fixes test board in the central shaft upper end of irrelevance test device, makes test board tight
Patch dehydrating inner drum top, and it is perpendicular to test the central shaft of device, the dewatering system of startup washing machine, operation 3～5min, to be washed
Clothing machine takes off test board after stopping operating, measure maximum radius and the least radius value running vestige on test board, can draw
The value of bucket irrelevance in laundry machine dehydration, and judge whether the value of bucket irrelevance meets the requirements in laundry machine dehydration, if it is determined that knot
Fruit, for meet the requirements, completes the concentricity inspection of dewatering system；
S3: if serious situation about being rebuffed occurs in S1 step test process, then check perpendicularity and the damping bullet of Washing machine dewatering shaft
Whether the length of spring, elasticity have problems, if existing problems, will check result and the dehydrating shaft of product or damping spring together
Deliver to reprocess line reprocess, complete the concentricity inspection of dewatering system；
S4: if bucket irrelevance is undesirable, then in the S3 step laundry machine dehydration that there is no problem or S2 step is tested
The parts of washing machine need to be checked respectively for, including the concentricity inspection of dehydrating inner drum, spring fastening installed surface liftoff
Highly check and the measurement of fifth wheel internal orifice dimension, and together deliver to reprocess line by testing result and problem component, complete dehydration system
The concentricity inspection of system.
Preferably, the radius measurement method running vestige in described S2 step on test board uses Centigrade scale to measure.
Preferably, in described S2 step in laundry machine dehydration the value of bucket irrelevance less than 10mm be then judged to qualified.
Preferably, in described S4 step the concentric angle value of dehydrating inner drum be judged within 5mm qualified.
Preferably, in described S4 step, the height error of the terrain clearance of spring fastening installed surface judges within 0.5mm
For qualified.
Preferably, in described S4 step, the measurement of fifth wheel internal orifice dimension uses stop-pass rule.
The inspection method of a kind of laundry machine dehydration system concentricity that the present invention proposes, checking process is simple, each step
Between interrelated, the most deep concentricity checking dewatering system, conveniently find the problem place of dewatering system concentricity,
Facilitate reprocessing of later stage, use the mode of most common failure investigation that the concentricity of dewatering system is checked, it is to avoid unnecessary
The dismounting of washing machine parts, saves the review time, reduces drain on manpower and material resources, and then improves the inspection of dewatering system concentricity
Look into efficiency, reduce check cost.
Detailed description of the invention
