The second limits value of maximum in carrying capacity limit value is equal, in the corresponding second eccentric load amount limit value of each load gear it is non-most
Big second limits value depends on corresponding load gear.
For example, due in revolving speed if load gear when user selectes highest dehydrating speed gear if wash load is lower
The difference of the detected value and true value of eccentric load amount can make washing facility generate biggish noise and use maximum limit when higher
The biggish eccentric load amount limit value of system value reduces this error, if the load gear of wash load is higher KB limit compared with
Small eccentric load amount limit value reduces dehydration noise.

It is set to revolving speed 2, sets revolving speed 3 for the dehydrating speed of washing facility if L21≤Lr < Lt.Wherein, (Fig. 3 is not by L2 < L21 < Lt
It shows).
With continued reference to attached drawing 4, as shown in figure 4, the weight of wash load is divided into 3 load gears in the present embodiment
(load capacity 1, load capacity 2 and load capacity 3 and load capacity 1, load capacity 2 and the corresponding load weight of load capacity 3 sequentially increase),
Each load gear respectively corresponds a second eccentric load amount limit value, the minimum that each second eccentric load amount limit value is included
Limits value is L0.Wherein, KB limit is Lt1 in the corresponding second eccentric load amount limit value of load capacity 1, and load capacity 2 is right
KB limit is Lt2, maximum in the corresponding second eccentric load amount limit value of load capacity 3 in the second eccentric load amount limit value answered
Limits value is Lt3.
If for example, being obtained currently when washing facility enters dehydrating operations according to the corresponding relationship of load weight and load gear
The corresponding load gear of wash load weight is load capacity 1, then compares the practical eccentric load amount Lr and limits value of washing facility
L0,
As Lr < L0, revolving speed 1 is set by the dehydrating speed of washing facility；
