Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the hardware composed structure schematic diagram for the tub-impact detector that the specific embodiment of the invention provides.Such as Fig. 1 institutes
Show, detection device includes the acceleration transducer 1 being arranged in casing of washing machine 6, to detect radial direction when interior bucket 5 rotates
The unit of acceleration acc, acc are meter per second2, further include the speed probe 2 for detecting 5 rotating speed rpm of interior bucket, the unit of rpm
For rev/min, the acceleration transducer 1 and speed probe 2 are connected with controller 3, and the controller 3 is according to following formula
The unit for obtaining the eccentricity value Dt, Dt=acc*M/rpm^2, Dt of the rotation of interior bucket 5 is rice, and wherein M is preset proportionality constant, when
When Dt is more than preset value D0, bucket is hit in the judgement of controller 3.
Due in washing machine structure, including interior bucket, outside, inner barrel and outer barrel forms staving to outer barrel, between inner barrel and outer barrel
Relative position fix, outer barrel is deviated and is deviated after being laid particular stress on interior bucket, and inner barrel and outer barrel displacement can regard the same as
's.So the eccentricity value Dt that the interior bucket 5 that controller 3 is obtained according to formula rotates can also regard the eccentricity value of outer barrel as.Work as Dt
When more than preset value D0, it that is to say that the eccentricity value of outer barrel is more than preset value, then bucket is hit in the judgement of controller 3.
Wherein, the value of proportionality constant M is according to the type, model and acceleration of gravity of used acceleration transducer 1
Deng determination.Using the acceleration transducer of different type and model, the value of the proportionality constant M is different.
Specifically, the device detects acceleration signal by acceleration transducer, detecting interior bucket by speed probe turns
Fast rpm calculates the offset of interior bucket by controller, the maximum allowable offset of setting is compared, whether to judge outer barrel
Babinet can be bumped against, to play the purpose of protection.
In this present embodiment, used acceleration transducer is preferably with U.S. new accelerometer, i.e. MXC6202XMP.With
For lower MXC6202XMP, calculating process is described in detail.
It derives as follows：
Actual acceleration a=(acc/S) * g, wherein S is U.S. new accelerometer（MXC6202XMP）Sensitivity, value is big
Small is 512；G=9.8 are acceleration of gravity.So actual acceleration a=(acc/512) * g.
w=2*π*f=2*π*(rpm/60)
Assuming that the offset of interior bucket is Dt, then have,
Dt=a/w^2=acc*g/S(2*π*(rpm/60))^2=(acc/rpm^2)*((3600*g)/(S*4*π^2))=M*
(acc/rpm^2),
Wherein, M is as proportionality constant, and M=(3600*g)/(S*4* π ^2), wherein g are acceleration of gravity, and S is to accelerate
Spend the sensitivity of sensor.
In this present embodiment, since the value size of the sensitivity S of MXC6202XMP is 512, so,
Dt=1.75* (acc/rpm^2),
So theoretically acc/rpm^2 be multiplied by 1.75 obtain be exactly interior bucket offset Dt（Unit：Rice）.Interior bucket it is inclined
Shifting amount Dt is also equal to the offset of outer barrel.
When normal dehydration or rinsing, the distance between outer barrel and babinet are in a certain range.Offset is generated when interior bucket rotates
Afterwards, close situation when the distance between outer barrel and babinet will be remote when occurring, when the distance between outer barrel and babinet are more than preset value
Afterwards, interior bucket rotation drives entire staving to hit babinet.Therefore the maximum allowable offset that interior bucket rotation can be set, when offset is small
When maximum allowable offset, then judge to work well.Otherwise, then judge exception occur, i.e., there is a phenomenon where hit staving.
Setting：
When static, shortest distance D=0.020m of staving and babinet.
The offset of maximum allowable staving is set by actual experiment as 0.016m, i.e. preset value D0=0.016m.
At a time t,
If offset Dt≤D0, judges that the displacement of staving is acceptable, continue to run with；
If offset Dt ＞ D0, judge that the displacement of staving is unacceptable, can cause tub-impact phenomenon.
Such as：
If the acc values that the t1 moment detects are that 57.15, rpm values are 100, the value that can calculate offset Dt is
acc/rpm^2*1.75=57.14/（100*100）=0.01m, because of Dt<D0, so being judged as that offset is acceptable, after reforwarding
Row.
If it is 100 that the acc values that the t2 moment detects, which are 102.86, rpm values,
The value for calculating offset Dt is acc/rpm^2*1.75=102.86/（100*100）=0.018m.
Because of Dt>D0, so being judged as that offset is unacceptable, then the device takes measures, and avoids staving from hitting babinet existing
As occurring.
In this present embodiment, the acceleration transducer is not limited to select MXC6202XMP, can also be other dresses
It sets, as long as being that by detection acceleration value.
In this present embodiment, the present apparatus can detect X-axis, Y-axis, any one direction in three directions of Z axis, any two
The displacement in direction either three directions can be by setting any one direction, any two direction or three directions
Displacement is as criterion.That is, the acceleration transducer 1 is for detecting X-axis in positive coordinate system, Y-axis, Z axis three
Radial acceleration when the interior bucket rotation in any one direction in direction, any two direction or three directions.
Specifically, assuming that X-direction is left and right directions, Y-direction is front-rear direction, and Z-direction is upper and lower directions.Bucket shakes in space
When dynamic, what these three directions were all offset, it is calculated according to radial acceleration, when any two of the interior bucket in three directions
When the offset Dt in direction or three directions is unacceptable, then the device takes measures, and avoids tub-impact phenomenon.
