Embodiment
The embodiment of the embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this
The embodiment of place description is merely to illustrate and explain the present invention embodiment, is not intended to limit the invention embodiment.
Fig. 1 is the washing machine eccentric detection method schematic flow sheet that one embodiment of the present invention is provided.As shown in figure 1,
The washing machine eccentric detection method that example embodiment of the present invention is provided, can include：
S101, when the interior bucket of washing machine is rotated, preset points on the interior bucket are periodically detected according to predetermined rotational angular
Linear acceleration.
For example, the detection for linear acceleration can indirectly be obtained by being detected to linear velocity.Fig. 2 is this
The washing machine eccentric detection method principle schematic that invention embodiment is provided.Washing machine inner tub top view as shown in Figure 2, example
Eccentricity detecting such as is proceeded by from the t0 times, the linear velocity at t0 moment is v0；When washing machine inner tub turns over predetermined rotational angular (example
Such as, 30 °) when, it is now the t1 moment, linear velocity is v1.It can be reached using the physical definition of acceleration by initial velocity v0
Speed v1, the time difference calculates current acceleration a1：
A1=velocity variables/time variation amount=(v1-v0)/(t1-t0).
In embodiments, the selection for predetermined rotational angular can be any angle for being capable of 360 ° of decile, for example,
15 °, 20 °, 60 ° etc..
In embodiments, the selection of preset can be the arbitrfary point on interior bucket, for example, interior bucket outer wall or opening are outer
Along upper point, the selection of particular location can be carried out according to the principle for being convenient for linear velocity detection, for example, consider linear velocity inspection
Survey the set location of sensor.
In embodiments, washing machine inner tub rotate when can be but not limited to washing machine inner tub start rotation when, i.e., from
Washing machine inner tub starts to begin to perform above-mentioned detection when rotating.In various embodiments, rotated for washing machine inner tub
When understanding when can be that washing machine inner tub rotates and reaches predetermined rotating speed or rotated in predetermined rotating speed is interval.
In such embodiment, it is considered to which the range of speeds of bias most possibly occurs in washing machine, so as to have in the range of speeds
Pointedly carry out eccentricity detecting.For example, the method provided in embodiment can be performed in 30-400rpm number rotaring section.
S102, it is determined that interior bucket rotate one circle during preset points linear acceleration maximum and minimum value.
For example, because possible eccentric situation is present, will cause washing machine inner tub (or variable-frequency motor, below within
It is described exemplified by bucket) during a circle is rotated, the linear acceleration of the preset points on interior bucket is continually changing, and change
Difference between maximum and minimum value can just reflect the degree of change, that is, eccentric degree.Therefore, the present invention's
In embodiment, the linear acceleration that internal bucket rotates preset points during a circle is sampled, therefrom filter out maximum with
Minimum value is to carry out eccentric judgement.
Fig. 3 is the example speed change curves that detect in the washing machine eccentric detection method that embodiment of the present invention is provided
Figure.As shown in figure 3, during bucket rotates a circle inside, linear acceleration can be continually changing, and speed is also constantly becoming
Change.In the embodiment shown in Fig. 3, for predetermined rotational angular selection still with shown in Fig. 2, be 30 °, so
Bucket can produce 12 acceleration a1, a2 ... a12 during rotating a circle inside.
S103, the linear velocity of preset is calculated when rotating a circle according to identified maximum and minimum value and interior bucket
When offset.
For example, calculating instant offset can be realized by following steps：
Determine the difference of the maximum and minimum value；And
It regard the business obtained by identified poor divided by described linear velocity as the instant offset.
By above-mentioned technical proposal, by being periodically detected on interior bucket the linear acceleration of preset points and according to identified
The instant offset of linear velocity calculating of preset can be to inclined when the maximum and minimum value of acceleration and interior bucket rotate a circle
Heart amount carries out quantitatively evaluating, realizes the Real-time and Dynamic Detection of offset.
In embodiments, it can be carried out eccentric judgement by calculating obtained instant offset.For example, will be resulting
Instant offset be compared with instant offset threshold value, when instant offset be less than instant offset threshold value when can consider
Washing machine can consider that washing machine is eccentric when instant offset is more than or equal to instant offset threshold value without bias.When
When judging to have eccentric, it can be alarmed and the process such as eccentric adjustment.

S105, when instant offset exceedes instant offset threshold value and/or cumulative offset more than cumulative offset threshold value
When, it is determined that eccentric.
What wherein step S104 and S105 considered is due to that washing machine working environment is unknown, thus by instant offset come
Judge that bias might have error or erroneous judgement, therefore introduce cumulative offset progress auxiliary judgment or calibration judgement.Specific real
Existing aspect, individually can enter according to cumulative offset and the comparative result of cumulative offset threshold value to washing machine with the presence or absence of bias
Row judges, for example, washing machine is can consider when cumulative offset is less than cumulative offset threshold value without bias, and when cumulative inclined
Heart amount can consider that washing machine is eccentric when being more than or equal to cumulative offset threshold value.When judging to have eccentric, it can be reported
The processes such as alert and eccentric adjustment.
