Specific embodiment
Each aspect of the present invention is related to a kind of washing machine imbalance or unbalance (OOB) detects and controls system, which adopts
With sensor, for example, being mounted on the accelerometer on bucket.More specifically, some aspects are related to one kind for vertical-rotation-axis
The OOB of formula washing machine (that is, top loading machines) detects and controls system.
Fig. 1 shows an example of the automatic washing machine 100 that can embody different aspect of the invention.Washing machine 100
Including being generally the opening 101 in the outer container of parallelepiped or the roof of shell 102 and shell 102, which is provided
Lead to the access of the suspension wash 103 in shell 102.Washing machine 100 further includes the different behaviour for controlling washing machine 100
The control panel (not shown) and hinged lid of work, the hinged lid covered during the use of washing machine 100 opening 101 and
It can be with Unscrew to provide the roof-mounted access for the multiple portions for leading to wash 103.Shell 102 accommodates wash
103, which is suspended in outer container 102 by multiple damping/damping units 106, so that the rotary shaft of wash 103
Line R substantially vertical (that is, being parallel to vertical axis of reference V shown in FIG. 1).It should be appreciated that in some embodiments, washing group
The rotation axis R of part 103 can be slightly slanted relative to vertical axis of reference V, without departing from the range of present disclosure.
Wash 103 includes the substantially cylindrical bucket 108 for accommodating cleaning-drum 107, which can be in bucket
It is rotated in 108 around rotation axis R.Wash 103 further comprises the central rods being mounted on the bottom surface of roller 107
105, with the laundry load facilitated in agitator treating component 103.
In use, laundry load is put into it in cleaning-drum 107 together with the laundry detergent compositions of suitable type and quantity
Afterwards, operator starts washing process by the interaction with control panel.The process is usually started with bucket pack period, wherein
Water enters washing tube 108 via inlet hose and across valve and nozzle (not shown).Washing tube 108 is fills up to predetermined water by water
Flat, this can depend on the size of user setting and/or wash load.Once it is horizontal to reach appropriate/setting, feed water valve is closed,
Washing machine 100 enters the washing cycle including multiple successive stages.For example, washing cycle may include agitation, the agitation
Process includes intermittent rotary of the central rods 105 towards one or two direction, that is, starts and stop the rotation of central rods 105, to produce
The circulation of raw effective washing movement and wash load.
It include the cleaning solution in roller 107 and/or washing tube 108 via central drain when completing washing cycle
(not shown) discharge.Next, the starting drying period, wherein cleaning-drum 107 is rotated with high-speed.This rotation of roller 107
The cleaning solution for turning that clothing is forced to absorb flows out from load and is passed through the hole 116 of 107 side of roller from roller 107
Middle outflow.It is related to the rotation of central rods 105 and washing tube 108 remain stationary or dallies it is worth noting that, stirring, and dries the period
It is mobile with relatively high speed (for example, being higher than speed associated with agitation) together to be related to central rods 105 and washing tube 108
To extract water outlet from wash load.Wash load can be further subjected to rinse cycle, and again in which opens feed water valve to permit
Perhaps clear water enters washing tube 108, is then stirred, drained and made roller 107 to rotate as discussed.For one or more
Rinse cycle usually repeats the above process.
During any operation of aforesaid operations, the clothing in wash 103 may become uneven.Specifically, when
When the uneven distribution of laundry load makes rotation axis R offset of the mass center of wash 103 relative to roller 107, occur not
Balance.With mass center mobile (that is, as imbalance increases), vibration of rotating cylinder 107 farther away from the center of wash 103
Component increase is swung, so as to cause 103 undue oscillation of wash.It is advantageous since the above problem is associated with undue oscillation
Be the vibration and/or imbalance of wash 103 are continuously monitored during the drying stage, and vibrate it is excessive when reduce get rid of
Dry speed and/or termination rotation completely.Correspondingly, can in wash 103 containing water when monitor the shifting of the wash
Dynamic and/or acceleration, to determine whether safely to execute drying stage (for example, during rinsing).Exist excessively not
In the case where equilibrium condition, can in wash 103 still containing water when stir clothing in the wash, to eliminate
Or unbalance condition is reduced, it reloads and drains without wasting water with the time.
If detecting unbalance condition during the drying stage, water and/or cleaning solution are discharged from bucket at this time, right
Laundry load redistribute can be very difficult.In general, bucket must fill the water again, to carry out redistributing agitation, from
And effectively redistribute laundry load.In addition, unbalance condition is tended to initially occur during agitation phase；That is, from
It is drained in bucket and before the starting drying stage.This initial unbalance condition severe exacerbation usually during the drying stage.Cause
This, especially for vertical rotary shaft wire type washing machine, when water collects in bucket, detecting and controlling for unbalance condition can be with
More effectively, because being easier to realize redistributing for laundry load.Correspondingly, each aspect of the present invention is got rid of in emptying bucket and starting
Unbalance condition is detected before the dry stage, so that the water for example still in bucket 108 can be used for redistributing unbalanced load.
In this respect, each aspect of the present invention uses peace before the drying stage (that is, when water still collects in bucket)
Sensor in a part of washing machine detects vibration or OOB.E.g., including master controller 115 and sensor board group
The control system of part 110 can be installed on washing tube 108.In the embodiment most preferably seen in such as Fig. 2A, sensor board group
Part 110 includes accelerometer 111, which is configured for generating corresponding with the acceleration being applied on accelerometer
Electric signal.Although describing the following explanation of washing machine in conjunction with the accelerometer 111 for detecting OOB situation, should manage
Solution, in an alternative embodiment, can be used other suitable sensors (such as displacement sensor etc.) to detect OOB situation.
In addition, although describing the following explanation of washing machine in conjunction with the sensor being installed on bucket 108, but it is to be understood that alternative
In embodiment, sensor can be installed on another part of washing machine 100, which is expected experience and OOB situation
Related detectable acceleration, displacement or vibration.
In some embodiments, accelerometer can sense bucket 108 in one direction (for example, substantial horizontal or vertical
Direction) on acceleration；And in other embodiments, accelerometer can sense acceleration along at least two sensing axes.
For example, accelerometer can be surface micro capacitance-type triaxial accelerometer, such as Freescale (Freescale)
Tri- axis digital accelerometer of MMA8452Q.Accelerometer 111 is mounted on circuit board 122, with provide sensor board component 110 with
Telecommunication between master controller 115.Accelerometer 111 and circuit board 122 are disposed in assembly housing 124, the component shell
Body is mounted on the exterior section of washing tube 108.In washing machine be vertical rotary shaft wire type and accelerometer 111 is configured to use
In along more than one sensing axes come sense acceleration embodiment in, a sensing axes can be substantially parallel to roller
107 rotation axis R (that is, vertical) and at least one sensing axes is with the rotation axis R of roller 107 orthogonal (that is, level
).
In some embodiments, and as shown in Figure 2 B, washing tube 108 may include mounting rack 127, mounting rack attachment
Onto the exterior section between adjacent side rib 120a, 120b on the outer surface of washing tube 108 of washing tube 108.Installation
Frame 127 has screw hole 128, for being mounted thereto sensor board component 110 using screw 126.Correspondingly, sensor
Board group part 110 with the smallest cost and only can carry out small modification to the hardware of existing wash and be added to known
Washing machine drum on.
Control system may further include processing unit (not shown), to pass for receiving from sensor board component 110
Sensor data simultaneously determine dynamic unbalance parameter.In the embodiment that sensor board component includes accelerometer, accelerometer can
To be configured for sensing acceleration along more than one sensing axes, and processing unit can determine more than one dynamic not
Balance parameters；For example, on (that is, in the vertical direction) direction for the rotation axis R for being arranged essentially parallel to roller 107
Acceleration and with the rotation axis R of roller 107 substantially orthogonal at least one direction on (that is, in the horizontal direction)
Acceleration.It is finally returned to Fig. 1, drive system 112 (for example, motor) is operably connected on roller 107, with (example
Such as, in the drying stage) driving roller 107 rotates, and master controller 115 is configured for control drive system 112 with for example
Adjustment drying speed.
In some embodiments, such as based on acceleration, displacement or the vibration measured, the number that can be provided from sensor
According to the uneven parameter of middle acquisition.If uneven parameter is more than predetermined uneven threshold value, facing for wash 103 can be determined
Boundary's unbalance condition.Predetermined imbalance threshold value can from experimental data by with the vibration that is generated when being more than critical unbalance condition
The correlation for swinging value determines, is then attached in the control system of given washing machine models.Further, for different washings
Period, there may be individual uneven threshold values, for example, uneven inspection or the uneven prison during the drying stage before draining
It surveys.If uneven parameter is more than predetermined uneven threshold value, master controller 115 can execute correction program to mitigate or prevent
The damage generated by unbalance condition.In embodiment, if detecting uneven shape when water still collects in bucket 108
Condition, then master controller 115 can star rebalancing agitation, as described herein.
Fig. 3 is depicted for monitoring (when water still collects in bucket 108) before the drying stage of wash 103
With the flow chart of the method for the vibration due to caused by dynamic unbalance in control vertical rotary shaft wire type washing machine 100.For this
The step of method is described sequence and is not intended to be limited to this method merely for illustrative purpose because understand be can be with not
The step of same logical order carries out these steps or can without departing from the present invention include additional or insertion.
This method starts 301 when filling the water to bucket, and then a part as the washing of laundry cycles or rinse stage is stirred
The content 310 of dynamic bucket.Start uneven detection drying 320 when completing agitation step 310, wherein roller 107 is got rid of with default
Dry speed is around the rotation axis R rotation default drying duration.It in some embodiments, can be in imbalance detection drying
A certain amount of water is discharged from bucket 108 before 320, this depends on many factors, including but not limited to: the model of washing machine, bucket
The amount of content (for example, clothing), and/or the water level in bucket 108 in 108.During imbalance detection drying, for example accelerate
The sensors such as meter, displacement sensor are installed in a part (for example, bucket 108) of washing machine, to measure instruction unbalance condition
One or more parameters.In step 330, control system obtains sensing data.
In some embodiments, in step 320, the default drying speed of imbalance detection drying is typically well below got rid of completely
The drying speed in dry stage.For example, the default drying speed of uneven detection drying can be the rank of 80RPM to 120RPM,
And the maximum drying speed for drying the stage completely can be 1,500RPM or more.In addition, compared with the complete drying stage, it is uneven
The default drying duration of detection drying is usually shorter duration, such as 10 seconds to 30 seconds.For example, in some implementations
In example, the default drying duration of imbalance detection drying is 20 seconds.The default drying duration can also according to it is many because
Element and change, such as content in washing machine models or type, specific washing cycle (for example, weight is dirty or softly washs) and bucket
The relative weight of object.Sensing data can be obtained with default sample rate, the default sample rate can also according to many factors and
Variation, such as default drying duration and/or default drying speed.In some embodiments, in step 330, control system
Sensing data will be obtained only for specific drying velocity interval or only for the specific duration of uneven detection drying.Example
Such as, in step 330, (such as last 45 seconds) sensing data can be obtained during the predetermined space of uneven detection drying.
In another example, in step 330, when (for example 72RPM is extremely in particular range for the speed of uneven detection drying
When 120RPM), sensing data can be obtained.
Sensing data is obtained from sensor, completes uneven detection drying until having determined, that is, in step 335
Imbalance detection drying has run the default drying duration, or when 333 obtain the data value for being higher than first threshold.?
Step 340, by the processing unit processes sensing data of control system, to obtain dynamic unbalance parameter, for example most very much not
Balance parameters.Due to it is low drying speed lower sensor signal level it is lower, in the case where having water in bucket low speed into
The uneven detection of row may be more difficult.Accordingly, it may be desirable to carry out more advanced data processing to sensor signal to obtain
Enough to the disequilibrium survey of precision.For example, processing original sensor data may include for example passing through Fast Fourier Transform
(FFT) or sensor signal is transformed into frequency domain from time domain by discrete fourier transform algorithm, and is obtained in speed region
Sensor values peak value.When handling original sensor data, can also be filtered using such as low-pass filter, bandpass filter etc.
Wave device, such as the frequency overlapped-resistable filter for adjusting sensor signal and/or for keeping sensor signal smooth.In step
340, processing sensing data can also include by sensing data and the drying speed measured during uneven detection drying
It is aligned and cuts sensor signal, that is, will be in region corresponding with the drying speed except preferred drying velocity interval
Sensing data exclude.For example, it is preferable to which drying velocity interval can be substantially near the maximum fast of uneven detection drying
The range of degree, such as 72RPM to 120RPM.
According to treated, sensing data determines different operation amount, to quantify dynamic unbalance situation, such as it is maximum
Uneven parameter.For example, maximum imbalance parameter can be based on acceleration, displacement or the vibration measured, this depends on being used
Sensor type.In some embodiments, maximum uneven parameter corresponds to uneven magnitude, for example, being based only upon one
The component of the sensing data in direction (for example, horizontal or vertical), and based on the durection component of sensing data from look-up table
Middle acquisition predetermined threshold.Additionally or alternatively, look-up table can provide predetermined threshold, these predetermined thresholds are based on one or more
A factor (for example, performance variable of the direction of sensor measurement sensing data and/or washing cycle) and change.
Once obtaining maximum uneven parameter from treated data in step 350, then in step 355 (for example, using
Look-up table as discussed) determine whether the uneven parameter of the maximum is more than predetermined threshold, i.e. second threshold.If most 355
Large unbalance parameter is more than second threshold, if and/or redistributing bucket more than first threshold in 333 sensing datas
Content.For example, in some embodiments, the content for redistributing bucket is included in step 360 and stops uneven detection drying,
And step 370 using the water starting still collected in washing tube 108 to the rebalancing agitation of the content of bucket (if
There are no attempted it is the maximum amount of redistribute agitation, be discussed more fully below in conjunction with step 365 and 380).Again it is putting down
During weighing apparatus agitation, the interval and quickly rotation of roller 107 are carried out in one or both directions, that is, start and stop roller 107
Rotation, to generate the circulation of wash load and redistribute.After rebalancing agitation 370, start subsequent imbalance
Detection dries and this method restarts in step 320, and reexamines with the presence or absence of unbalance condition (for example, then
Whether the uneven parameter of the maximum of acquisition is more than predetermined second threshold or whether the sensing data then obtained is more than predetermined
First threshold).
If determining that the uneven parameter of the maximum then obtained still above predetermined threshold, can repeat in step 355
The rebalancing agitation 370 of the content of bucket.However, certain loads possibly can not be rebalanced by stirring program.Cause
This, rebalancing the content of bucket can also include determining whether to have been carried out the weight of maximum quantity in step 365 first
New balance agitation.If it is determined that having been carried out the rebalancing agitation of maximum quantity, then executes in step 380 to user and send out
Alarm out, to notify user to redistribute the content of washing tube 108 manually, to complete washing cycle.In some realities
It applies in example, washing cycle will stop, being inputted until receiving user associated with washing cycle is restarted (for example, if
User has redistributed the content of washing tube 108 manually).In some embodiments, washing cycle can be in imbalance
Situation continues in the case where still having.For example, alarm is not executed 380, even if having been carried out maximum quantity
Agitation is rebalanced, washing cycle can also be in step 399 to dry period continuation, and if roller is hit during drying
Cabinet, then drying will stop immediately.If being less than predetermined threshold in the maximum uneven parameter of step 355, incited somebody to action in step 390
Collect in the water discharge in bucket 108.Then, continue washing cycle in step 399.In other words, it is washed if uneven detection is used as
The a part for washing the period carries out, then washing cycle can be continued with rinse cycle or subsequent washing cycle, depends on the circumstances.Class
As, if uneven detection is carried out as a part of rinse cycle, washing cycle can be to dry period or then
Rinse cycle continues, and depends on the circumstances.
Sensor signal 410 during Fig. 4 depicts the washing process according to the one or more aspects of present disclosure is shown
Example property indicates.Control marking signal 420 is further depicted, instruction drying speed or agitation speed have reached target.Such as Fig. 4 institute
Show, after agitation phase 430, and when still having water in bucket, is reaching target drying speed shown in control mark 420
Before, such as based on the acceleration higher than threshold value sensed, unbalance condition is detected at 440.Detect uneven shape
