The specific embodiment
Embodiment 1
Below, Yi Bian with reference to accompanying drawing embodiments of the present invention are described on one side.In addition, the present invention is not limited by present embodiment.
Fig. 1 be embodiment 1 washing machine (drum-type) be used to detect and suppress block diagram owing to the control device of the unbalanced vibration that causes of washings.In Fig. 1, the washing machine of embodiment 1 comprises: housing 10; Cylinder 11, it is used to accommodate washings and makes the washings rotation; Motor 12, the speed of index drum 11 makes this cylinder 11 rotations on one side it is used on one side.The washing machine of embodiment 1 also comprises: tank 13, and portion is provided with cylinder 11 and water is housed within it; Lid 18, it has the washings input port; Sealing gasket 14, it is used for being connected this tank 13 and the lid 18 with washings input port by the gap of landfill tank 13 and the lid 18 with washings input port; Support spring 15, it is used to keep the posture of tank 13; Vibration isolation damper 16, the vibration that it produces when being used to reduce the motor rotation and reduce to vibrate transmission to housing 10, floor.
The washing machine of embodiment 1 also comprises the vibration detection device 17 of the vibration that is used to detect tank 13.As the example of vibration detection device 17, in embodiment 1, adopted the acceleration transducer of variation that can numeral output acceleration, but also can adopt the acceleration transducer of the simulation way of output exported as voltage change of variation that can degree of will speed up.
The acceleration transducer of embodiment 1 has adopted the capacitance type acceleration transducer that the variation of electrostatic capacitance is transformed to voltage.In addition also can use piezoelectric electro resistance type acceleration transducer etc.These so-called MEMS (Micro Electro Mechanical Systems) sensor is the small sensor of making of the semiconductor integrated circuit manufacturing technology, in recent years, by with low-cost volume production, and is used to various people's livelihood equipment.The advantage of MEMS type sensor is, small-sized, weigh light, and also MEMS type sensor itself is little to the influence of vibration, is suitable as vibration detection device 17.In addition, the acceleration transducer of embodiment 1 adopts and can be used to detect the vibration of a plurality of directions with the sensor of 3 of 1 chip detection.Therefore, the rotating speed in the time of can catching along with dehydration reliably rises and the vibration mode of intricately variation, and judges various imbalances.Wherein, acceleration transducer also can be the sensor of diaxon.
The installation site of the vibration detection device 17 of embodiment 1 is front side, tank 13 top.The unbalanced of washings in cylinder 11 is present under the anterior state, the vibration of cylinder 11 when rotation is quickened at a high speed compared greatly with the unbalanced situation that is present in the rear portion, therefore need forwardly have and avoid making cylinder 11 to quicken under the big unbalanced state as far as possible to rotating at a high speed.Forwardly have under the unbalanced situation, tank 13 rock also easily forwardly that side obviously manifests, so also preferably make the installation site of vibration detection device 17 be positioned at the front portion.
Fig. 2 A and Fig. 2 B are the structure chart of expression as the installation site of 3 axle acceleration sensors of vibration detection device 17.It seems that from the main body front in the middle of the detection axle of 3 axle acceleration sensors, X-axis is based upon on the left and right horizontal direction, on (rotation) direction, upwards, can monitor the action of tank 13 below the Z axle is based upon haply before and after Y-axis is based upon roughly three-dimensionally.
It is the top of main body front side that vibration detection device 17 is installed in apart from vibration isolation damper 16 position farthest.Thus, particularly when low speed when rotation dehydration produces rocking of big displacement, also can detect vibration in high sensitivity.
Table 1 is the figure of major parameter of the acceleration transducer of expression embodiment 1.
Table 1
SPI: SPI (Serial Peripheral Interface)
Output type is digital SPI (digital SPI), and is the multiaxis detection type sensor of acceleration that can detect 3 axles (X, Y and Z) of quadrature.The acceleration detection scope can be set at the 1st detection range (2g～+ 2g) and the 2nd detection range (6g～+ 6g) these two kinds, can set and the change detection scope according to the internal register of sensor.In addition, for the sensitivity of each detection range, the sensitivity of the 1st detection range is about 1024[LSb/g], the sensitivity of the 2nd detection range is about 340[LSb/g], compare with the 2nd detection range, the 1st detection range highly sensitive, and the acceleration detection scope is narrow.
That is, under the situation of having set the 1st detection range,, can measure the unbalanced of cylinder 11 exactly by dwindling the acceleration detection scope and improving sensitivity.Therefore, can carry out trickle control.To this, under the situation of having set the 2nd detection range, by desensitization and enlarge the acceleration detection scope, can be with sense acceleration on a large scale, also can suitably carry out correspondence having produced under the situation of abnormal vibrations etc.
In addition, also can be can switch 3 above acceleration detection scopes (for example ± 2g, ± 6g, ± 8g) acceleration transducer, preferably with the vibration permissible range of washing machine, the correspondingly selected best sensor of parameters such as cylinder maximum speed of dehydration procedure.
Because the output from acceleration transducer is digital, so compare with analog, directly import easily to microcontroller, in addition, noise resistance for the noise that is produced by the inverter circuit of drive motor 12 etc. is strong, do not need noise removal device etc., can suppress the main cause that cost increases.
Fig. 3 A, Fig. 3 B and Fig. 3 C are the curve maps that detected acceleration is write down with drum rotation speed as an example of the output of the acceleration transducer in the dehydration procedure of tumbling-box washing machine.
When beginning to dewater as can be known, along with the climb acceleration of drum rotation speed also rises, each detects the degree difference of the amplitude of axle.In addition as can be known, X, Y-axis near 900rpm roughly, surpass as the 1st detection range ± 2g, with respect to this, the Z axle near the 600rpm of low speed, surpassed as the 1st detection range ± 2g.This be because, the acceleration transducer of embodiment 1 is the type that not only can detect dynamic acceleration but also can detect acceleration of gravity, all the time to Z axle weight application acceleration (under the influence of ≈+1g), reach+surplus of 2g is littler than other diaxons.Amplitude (Peak-to-Peak value) itself and other diaxon peer-levels, but need enlarge detection range in the moment early.
Like this, as can be known when the change detection scope, Yi Bian Yi Bian the upset condition that needs to observe all the time each different acceleration change detection scope suitably.
Fig. 4 is the flow chart of hand-off process of the acceleration detection scope in the dehydration procedure of expression embodiment 1, switches the acceleration detection scope according to the acceleration that is detected.Below, each step is described successively.
At first, after dehydration procedure begins, utilize control part 20 (for example microcontroller) degree of will speed up detection range to set the 1st acceleration detection scope (± 2g) (step 1) for.During low speed after dehydration procedure just begins, because rocking of tank 13 is small, so preferably with highly sensitive setting sense acceleration.
Then, cylinder 11 begins rotation (step 2).Afterwards, monitor acceleration all the time, judge whether the acceleration that is detected surpasses the 1st acceleration detection scope (step 3).In step 3, if in the 1st acceleration detection scope, then not changing detection range ground, the acceleration that is detected do not continue rotation, judge whether to have passed through dehydration setting-up time (step 4).In step 3, be judged as under the situation that has surpassed the 1st acceleration detection scope, switch to the 2nd acceleration detection scope (± 6g) continue rotation (step 5) afterwards.Afterwards, judge whether to have passed through dehydration setting-up time (step 6).In step 6, being judged as under the situation of not passing through the dehydration setting-up time, continue rotation, return step 6.In step 6, be judged as under the situation of having passed through the dehydration setting-up time, finish the rotation (step 7) of cylinder 11.In addition, in step 4,, return step 3 being judged as under the situation of not passing through the dehydration setting-up time.In step 4, be judged as under the situation of having passed through the dehydration setting-up time, finish the rotation (step 7) of cylinder 11.
Fig. 5 is the sequential chart that expression is equipped with the hand-off process of acceleration detection scope under the situation of acceleration transducer of the vibration that can detect a plurality of directions, in the dehydration procedure.Fig. 5 represents individually to switch the example of processing of the acceleration detection scope of each, but also can side by side carry out hand-off process.
As the curve map of observing acceleration is as can be known, the acceleration amplitude of X-axis and Z axle about equally, and that amplitude is compared in the vibration on the Y-axis and the vibration of other diaxons is little.As can be known because the Z axle comprises the acceleration of gravity of above-below direction, so shown the output of 1g in the dehydration incipient stage, the moment that arrives 2g is also Zao than X-axis.On the other hand, Y-axis in whole dehydration procedure is ± 2g is with interior acceleration, can detect with the acceleration detection scope 1 of initial setting.In addition because the detection side is to difference and the different vibration of amplitude equal change at random according to the biasing situation that is attached to the washings cylinder 11 in and when each running, so sometimes this to vibrate be to be inclined to the vibration different with the acceleration waveform of Fig. 5., as shown in Embodiment 1, each direction is switched the acceleration detection scope, can detect vibration with the good setting of sensitivity all the time by variation according to acceleration.
Below, Yi Bian with reference to accompanying drawing embodiment 2 is described on one side.In addition, the present invention is not limited by present embodiment.
Fig. 6 is the detection of embodiment 2 and the block diagram by the control device of the unbalanced vibration that causes of washings that suppresses washing machine (drum-type).In the structure of Fig. 6, comprise the speed detector 21 of the rotating speed that detects cylinder 11, can switch the acceleration detection scope according to the rotating speed that is detected.
Fig. 7 is the flow chart of hand-off process of the acceleration detection scope in the dehydration procedure of expression embodiment 2, switches the acceleration detection scope according to the rotating speed of cylinder 11.Below, each step is described successively.
After dehydration procedure begins, utilize control part 20 degree of will speed up detection ranges to set the 1st acceleration detection scope (± 2g) (step 1) for.
Then, cylinder 11 begins rotation (step 2).Afterwards, rotating speed is risen, judge whether to reach acceleration detection scope speed-changing (in embodiment 2, being 330rpm) (step 3).In this period, also monitor acceleration all the time, stop in case detecting the above acceleration of regulation acceleration that causes abnormal vibrations then make to rotate.In step 3, do not reach at the rotating speed that is judged as cylinder 11 under the situation of regulation rotating speed, continue to promote rotating speed and return step 3.In step 3, reach at the rotating speed that is judged as cylinder 11 under the situation of regulation rotating speed, be maintained under the constant state in rotation cylinder 11, degree of will speed up detection range switches to the 2nd acceleration detection scope.After switching to the 2nd acceleration detection scope, begin to quicken the rotation (step 4) of cylinder 11 once more.Afterwards, judge whether to have passed through dehydration setting-up time (step 5).In step 5, being judged as under the situation of not passing through the dehydration setting-up time, continue rotation, return step 5.In step 5, be judged as under the situation of having passed through the dehydration setting-up time, finish the rotation (step 6) of cylinder 11.
In addition, (120～300rpm) rotating speed gets final product the speed-changing of acceleration detection scope so long as avoid the fierce resonance zone of acceleration change.In addition, Yi Bian make cylinder 11 with the constant speed rotation, Yi Bian switch the acceleration detection scope.Thus, can prevent to surpass detection range, be absorbed in the predicament that can't detect owing to rising suddenly at the resonance zone acceleration.
Fig. 8 A, Fig. 8 B, Fig. 8 C and Fig. 8 D are the sequential charts that is illustrated in the hand-off process of acceleration detection scope under the situation of the acceleration transducer that the vibration that can detect a plurality of directions has been installed, in the dehydration procedure.In this processing, switch the acceleration detection scope of each simultaneously, also can individually switch.
During the dehydration beginning, after setting the 1st acceleration detection scope for, drum rotation speed is risen, passed through to keep the constant speed of 330rpm behind the resonance zone, in case, then switch to the 2nd acceleration detection scope through the stipulated time.Since the amplitude of the resonance zone in the embodiment 2 with respect to the 1st acceleration detection scope (± 2g) surplus arranged, be no problem so switch after by resonance zone.
Fig. 9 is the flow chart of the hand-off process of the acceleration detection scope in the expression dehydration procedure, and the rotating speed switching acceleration detection scope according to cylinder 11 judges whether to continue dehydration.Below, each step is described successively.
After dehydration procedure begins, utilize control part 20 degree of will speed up detection ranges to set the 1st the highest acceleration detection scope of detection resolution (± 2g) (step a) for.
Then, cylinder 11 begins rotation (step b).Then, implement to untie operation (step c) for the winding of eliminating clothing, biasing.Afterwards, begin to quicken the rotation (step d) of cylinder 11.
Then, judge whether sense acceleration has surpassed threshold value 1 (step e) in acceleration.Here, so-called threshold value is meant according to the relation of acceleration and vibration the vibration of tank 13 is converted into the value that acceleration is represented for the vibration under the situation more than the specific vibration, and threshold value 1 is as the value of the benchmark that detects abnormal vibrations in the 1st detection range.
In step e,, judge whether to reach acceleration detection scope speed-changing (step I) being judged as sense acceleration above under the situation of threshold value 1.In step I, be judged as under the situation that does not reach acceleration detection scope speed-changing, return step e.In step I, be judged as under the situation that has reached acceleration detection scope speed-changing, degree of will speed up detection range is set 2nd detection range (± 6g) (the step j) of detection range than the 1st acceleration detection scope big (detection resolution is low) for.Then, judge whether sense acceleration has surpassed threshold value 2 (step k).Here, threshold value 2 is values that conduct detects the benchmark of abnormal vibrations in the 2nd detection range.In step k,, judge whether to have passed through dehydration setting-up time (step l) being judged as sense acceleration above under the situation of threshold value 2.In step l,, return step k being judged as under the situation of not passing through the dehydration setting-up time.In step l, being judged as under the situation of having passed through the dehydration setting-up time, finish the rotation of cylinder 11, finish dehydration, enter subsequent processing (step m).In step e, surpassed under the situation of threshold value 1 being judged as sense acceleration, and in step k, surpassed under the situation of threshold value 2 being judged as sense acceleration, be considered as the state of abnormal vibrations, make the rotational delay of cylinder 11 and stop (step f).Then, judge owing to sense acceleration has surpassed the number of times that cylinder 11 that threshold value causes stops whether to reach stipulated number (step g).In step g, do not reach under the stipulated number situation being judged as the number of times that 11 rotations of the cylinder that causes greatly owing to extent of vibration stop, returning the step a running of dewatering again.Reach under the situation of stipulated number being judged as the number of times that 11 rotations of the cylinder that causes greatly owing to extent of vibration stop, even think that further continuing the dehydration running also can't eliminate imbalance, carries out error notification (step h) to the user.
In this wise, by improving the detection resolution of acceleration transducer in the low speed rotation zone in dehydration procedure, even small extent of vibration also can be carried out vibration detection accurately, degree of will speed up detection range is set narrowlyer below cylinder 11 regulation rotating speeds.And at the regulation rotating speed when above, to compare the acceleration detection scope big with the situation below the regulation rotating speed, also can become with the rotation along with cylinder 11 at a high speed and the acceleration degree that increases is corresponding.So, it is corresponding to produce more cataclysmal extent of vibration with the rising along with drum rotation speed, and avoids abnormal vibrations expeditiously.
In addition, also can be at the rotating speed of cylinder 11 resonance zone (below 120～300rpm) and the acceleration that detects of vibration detection device 17 moment of having surpassed the acceleration of regulation make the cylinder rotational delay, in the very little zone of acceleration below resonance zone, at the acceleration that detects tank 13, under the big situation of extent of vibration, rotational delay by making cylinder 11 or stop to prevent abnormal vibrations in advance, thereby can realize improving the running efficiency and the low vibration dehydration of dehydration procedure.
Embodiment 3
Below, Yi Bian with reference to accompanying drawing embodiment 3 is described on one side.In addition, the present invention is not limited by present embodiment.
In addition, the present invention also can be applied in the matting of tumbling-box washing machine.
Figure 10 is the flow chart of hand-off process of the acceleration detection scope in the matting of expression tumbling-box washing machine.The matting of tumbling-box washing machine is (tumbling) mode of rolling, and, lifts washings by the projection body of the inner side surface that is installed in cylinder 11 to top that is, upborne washings is fallen and removes dirt.Therefore, the impact when falling (acceleration) is big more, and degree of cleaning also can improve more, according to the rotating speed of Acceleration Control motor 12, can improve cleaning degree.But the acceleration of the tank 13 that is produced by the drop impact of the clothing in the matting is compared very little with the acceleration of dehydration procedure (in particularly rotating at a high speed).Therefore, cleaning according to Acceleration Control under the situation of running, must improve the sensitivity of vibration detection.
The common order of the matting of tumbling-box washing machine is, with the running of stipulated time, regulation-the stop time limit being reversed cylinder 11 repeatedly between both forward and reverse directions action.If make cylinder 11 on same direction, continue rotation, then become and cause between the clothing and twine, clean the main cause that inequality, cleaning force reduce mutually, but cylinder 11 is reversed termly and can prevent to twine between the clothing.Therefore, both eliminated the winding of clothing when each counter-rotating, drop impact (being the vibration of tank 13) also changes.Preferably set with the highest acceleration of sensitivity and detect vibration according to the vibration (acceleration) of this change.Below, each step is described successively.
After matting begins, utilize control part 20 degree of will speed up detection ranges to be set at the 1st acceleration detection scope (± 2g) (step 1).Then, cylinder 11 begins rotation (step 2).Afterwards, Yi Bian on one side monitor acceleration all the time and implement to roll.
In rolling, judge all the time whether sense acceleration surpasses the 1st detection range (step 3).In step 3, surpassed under the situation of the 1st detection range being judged as sense acceleration, after switching to the 2nd acceleration detection scope, degree of will speed up detection range continues rotation (step 5).Then, judge to rotate whether passed through the stipulated time (step 6) the duration of runs.In step 6, do not pass through under the situation of stipulated time the duration of runs being judged as rotation, return step 6.In step 6, passed through under the situation of stipulated time the duration of runs being judged as rotation, stop the rotation (step 7) of cylinder 11.Then, judge whether to have passed through cleaning setting-up time (step 8).In step 8, be judged as under the situation of having passed through the scavenging period that sets, finish the cylinder rotation, enter subsequent processing.In step 8, be judged as under the situation of not passing through the scavenging period that sets, judged whether to pass through the rotation dwell time (step 9) of regulation.
In step 9, under the situation that is judged as the rotation dwell time of not passing through regulation, return step 9.In step 9, under the situation that is judged as the rotation dwell time of having passed through regulation, carry out cylinder rotation counter-rotating (step 10).Then, return step 1.In addition, in step 3,, do not change detection range ground and continue rotation, judged whether to pass through the rotation (step 4) duration of runs of regulation being judged as sense acceleration above under the situation of the 1st detection range.In step 4, under situation about being judged as not, return step 3 through rotation duration of runs of regulation.Under the situation that is judged as rotation duration of runs of having passed through regulation, stop the rotation (step 7) of cylinder 11.
As described above, because the acceleration that detected also changes greatly according to the structure of running operation (cleanings, dehydration etc.), drum rotation speed or the body of washing machine (size of the characteristic of vibration isolation damper 16, support spring 15, layout, cylinder 11, angle of inclination, vibration detection device 17 be provided with place etc.), so the acceleration detection scope that switches to the best at various situations is important.Thus, by switching the acceleration detection scope, can realize high-precision vibration detection according to sense acceleration, drum rotation speed.
In addition, be not only under the acceleration that vibration detection device 17 is detected because the rotating speed of cylinder 11 is risen as embodiment 1 becomes big situation, and producing the unbalanced rotating speed decline that waits some reason to make cylinder 11 owing to state because of washings, under the situation that the acceleration that vibration detection device 17 is detected diminishes, the acceleration of certain direction is in the moment of the acceleration detection scope of regulation, by dwindling the acceleration detection scope of this direction, can realize high-precision vibration detection.
In addition, all be in moment of the acceleration detection scope of regulation, by dwindling the acceleration detection scope of all directions, not only can improve the precision of vibration detection, but also can simplify the switching of acceleration detection scope at the acceleration of all directions.
In addition, when the rotation (rotating speed) of cylinder 11 is risen, as long as monitor on one side with the sense acceleration that prevents vibration detection device 17 surpass the peak acceleration detection range (in embodiment 3 for ± 6g), the rotating speed of one side index drum 11, just can realize preventing abnormal vibrations and the maximum high speed rotation that limits, thereby can realize low vibration and improve dewatering.
Thus, washing machine of the present invention comprises: cylinder, and its periphery is provided with permeable hole; Tank, portion is provided with cylinder and is used to store washings within it; Motor, it is used for the head roll rotation; Housing, it is used to accommodate tank; Speed detector, it is used to detect the rotating speed of cylinder; Vibration detection device, it is made of vibration that can detect tank and the acceleration transducer that switches the different a plurality of acceleration detection scopes of minimum acceleration resolution ratio; Control part, it is based on the output of vibration detection device, control motor and vibration detection device, control part switches the acceleration detection scope according to the rotating speed of cylinder, thereby the extent of vibration (acceleration) according to the tank that correspondingly changes with rotating speed is suitably set the acceleration detection scope, the highest detection range of sensitivity can be used thus, the precision of vibration detection can be realized improving.
In addition, washing machine of the present invention comprises: cylinder, and its periphery is provided with permeable hole; Tank, portion is provided with cylinder and is used to store washings within it; Motor, it is used for the head roll rotation; Housing, it is used to accommodate tank; Vibration detection device, it is made of vibration that can detect tank and the acceleration transducer that switches the different a plurality of acceleration detection scopes of minimum acceleration resolution ratio; Control part, it controls motor and vibration detection device based on the output of vibration detection device, and control part switches the acceleration detection scope according to the acceleration that is detected, and can use the highest detection range of sensitivity thus, can realize improving the precision of vibration detection.
Thus, because can reduce vibration, noise in the dehydration procedure particularly, so can realize low vibration, low noise running and because the running efficiency height shortens the duration of runs.
And, during acceleration more than vibration detection device detects prescribed level, control part increases the acceleration detection scope of vibration detection device and fixes this acceleration detection scope, thus, can be controlled to the suitably high setting of sensitivity and surpass the acceleration detection scope of acceleration transducer, can realize the precision of raising vibration detection with the peak value that prevents acceleration.
And, control part the dehydration resonance zone before or/and after, by switching the acceleration detection scope of vibration detection device, the many resonance zone ground of change that can avoid acceleration in dehydration procedure switches the acceleration detection scope, carries out stable acceleration detection in the dehydration resonance zone.
And, the moment that has surpassed the acceleration detection scope in the sense acceleration of the either direction of the vibration detection device of the vibration that can detect a plurality of directions, control part enlarges the acceleration detection scope of the direction that has surpassed the acceleration detection scope, thus, by indivedual acceleration detection scopes of switching on each vibration detection direction, can on each vibration detection direction, carry out vibration detection with the highest sensitivity.
And, the moment that has surpassed the acceleration detection scope in the sense acceleration of the either direction of the vibration detection device of the vibration that can detect a plurality of directions, control part enlarges the acceleration detection scope of all directions, thus, can simplify the hand-off process that control part carries out the acceleration detection scope.
And, the moment in the sense acceleration of the either direction of the vibration detection device of the vibration that can detect a plurality of directions is in the acceleration detection scope of regulation, control part dwindles the acceleration detection scope that is in the direction in the acceleration detection scope, thus, can select the highest acceleration detection scope of sensitivity according to extent of vibration, can realize improving the precision that detects vibration.
And, the moment in the sense acceleration of all directions of the vibration detection device of the vibration that can detect a plurality of directions is in the acceleration detection scope of regulation, control part dwindles the acceleration detection scope of all directions, thus, can select the highest acceleration detection scope of sensitivity according to extent of vibration, not only can realize improving the precision that detects vibration, and can simplify the hand-off process that control part carries out the acceleration detection scope.
And control part switches the acceleration detection scope of vibration detection device under the rotating speed of cylinder is constant state, thus can carry out reliably when drum rotation speed rises or the acceleration change when descending more than the vibration detection of rotary area.
And control part is set at minimum with the acceleration detection scope of vibration detection device when cylinder begins to rotate, thus the vibration detection when can be all the time carrying out the less dehydration of acceleration and begin with highly sensitive setting.
And, the rotating speed of control part index drum surpasses the peak acceleration detection range with the sense acceleration that prevents vibration detection device when drum rotation speed rises, thus, particularly in dehydration procedure, can be while preventing that abnormal vibrations from dewatering with high as far as possible high speed rotation, vibrates and the raising dewatering thereby can realize simultaneously hanging down.
And, because acceleration transducer can switch the acceleration detection scope by the setting value of only switching internal register, thus do not need to be provided in addition switching the switch of acceleration detection scope, thus can simplify vibration detection device.
