Description
Technical field
The present invention relates to a kind of control method of automatic drying.
Background technology
In general, the mode of washing that roller washing machine adopted is: washing agent and washings and washings are being put under the state of cylinder, washed at cylinder that rotates under the effect of the driving force that motor part is conducted and the frictional force between the washings by utilizing.This mode of washing is less to the damage of washings, and washings can not twine mutually, and can obtain the clean result of beaing and rubbing.
Along with the function of this roller washing machine constantly improve and product senior day by day, except function with washing and dehydration, occurred now a kind of roller washing machine that has drying function concurrently again, and people are in rising trend to the demand of this roller washing machine that has drying function concurrently now.
This roller washing machine that has drying function concurrently can utilize fan and the heater that is installed in the bucket outside, air outside is forced to suck and heated, to be transported to the inside of bucket through the high temperature air of heating then, thereby realize oven dry washings.
Have concurrently the washing and the equipment of drying function except this, positive day of a kind of roller dryer attracts attention, and this roller dryer is specifically designed to oven dry, can be at short notice dries a large amount of clothings is disposable.
Below the automatic drier that is adopted in existing automatic drying roller washing machine and the roller dryer is described.
As shown in Figure 1, existing roller washing machine is to adopt manual control mode to realize drying stroke, this manual drying mode needs earlier to select the drying stroke (course) oneself wanted by the user, and sets suitable drying time according to the amount of washings, carries out drying stroke then.
But there is following problem in aforesaid manual drying mode: if fail to realize drying stroke accurately, and so will be fully with the washings oven dry, if opposite excessively oven dry then can't reach the desired oven-dried condition of user.
In order to address the above problem, developed a kind of control method as described below now.At first, as shown in Figure 1, the bucket temperature sensor Ttub that is used for responding to the bucket internal temperature is equipped with in the inside of bucket 11, and the inside of pipeline 12 is equipped with and is used for the Tube Temperature Sensor TA1 of induction pipe temperature inside.When carrying out drying stroke, can utilize above-mentioned bucket temperature sensor Ttub and Tube Temperature Sensor TA1 to respond to bucket 11 inner and pipeline 12 temperature inside, automatically judge aridity according to bucket temperature T tub and the temperature difference between the pipe temperature TA1 (Δ T) sensed then, and control drying stroke in view of the above.
In condensation drying mode (condensing dry method), after the dehydration stroke finishes, the air of high temperature low humidity can flow into the inside of bucket, these air that flow into bucket inside can absorb the moisture in the washings, thereby become hot and humid air, these hot and humid air can become the air of low temperature and low humidity by condensation process in the process of pipeline of flowing through then.Such process is carried out repeatedly, just can realize the oven dry to washings.
Here, the air that has become the low temperature and low humidity state by condensation process can become the air of high temperature low humidity through after the heating of heater, flow in the bucket again then.
In aforesaid drying course, the variations in temperature of bucket temperature sensor Ttub and Tube Temperature Sensor TA1 is as follows:
As shown in Figure 2, at oven dry initial stage (Beginning dry), because the washings of bucket inside contains more water, therefore the air (Low temperature Low humidityAir) that has low temperature and low humidity flows through pipeline, the amount that collects in the cooling water of lower end of duct and condensed water simultaneously is also not many, and is in low-temperature condition.In this case, the temperature sensor of bucket temperature sensor Ttub and Tube Temperature Sensor TA1 does not almost have any difference.
Drying mid-term (Middle dry), in order to remove the moisture that is contained in the washings in the bucket, have the inside that constantly flow into bucket through the high temperature air of heating, thereby the bucket temperature inside is risen, also have hot and humid air flow piping simultaneously, thereby condensation meeting this moment actively brings into play its effect, thereby the temperature sensor of bucket temperature sensor Ttub and Tube Temperature Sensor TA1 is slowly risen, and their curve map (profile) is identical.
In oven dry latter stage (End Dry) and since the moisture in the washings removal to a certain degree, therefore have the air flow piping of high temperature low humidity, the temperature sensor of Tube Temperature Sensor TA1 can rise at this moment; Simultaneously, in this state, because the aridity of washings is higher, thereby condensed water can reduce, and cooling water then increases, and can slowly descend by this temperature sensor that influences bucket temperature sensor Ttub.
In the middle of the process that aforesaid drying stroke is carried out, the difference between the temperature sensor of bucket temperature sensor Ttub and Tube Temperature Sensor TA1 be temperature difference Δ T as shown in Figure 3, can As time goes on increase.
, aforesaid temperature difference Δ T can be used as aridity judgment value Δ here, and mark off different oven dry grades (level) such as weak oven dry, standard oven dry and strong oven dry, carry out then and the corresponding drying course of these oven dry grades as benchmark.
But the temperature difference between the aforesaid temperature of utilizing bucket temperature inside and pipe interior realizes that also there are following problems in the mode of drying stroke.
In the prior art, in order to dry algorithm (algorithm) automatically, need utilize temperature sensor to come indirect detection washtub humidity inside.Promptly need from pipeline or bucket temperature inside sensor, to obtain the temperature sense value, thereby calculate anticipation humidity.
That is to say, when drying, need calculate the mean value of the detected data of temperature sensor in certain interval, and judge aridity in view of the above.But, all have nothing in common with each other owing to be used for forward and backward cycle, feedwater cycle, the drainage period of main motor of head roll, and the cycle of these cycles and calculated data mean value be inconsistent, therefore can cause data stability decline.
Shown in Fig. 4 a, in the process that oven dry is carried out, temperature difference Δ T between the temperature sensor of Tube Temperature Sensor and bucket temperature sensor is to the situation of change of time, Fig. 4 b be Fig. 4 a's (first) part zoomed-in view, as can be seen from the figure, the forward and backward cycle of motor is consistent with the time point that shake appears in temperature data.
Shown in Fig. 4 b, be to be difficult to aridity is made accurate judgement under the situation that occurs shaking at temperature data, therefore can make the reliability decrease of automatic oven dry.
In addition, for utilizing temperature difference between bucket inside and the pipe interior to realize the mode of drying stroke, because what use is fixing aridity judgment value, therefore the structure of air flow circuit can be different, like this, being subjected to the influence of deviation, the deviation on the pipe configuration and the factors such as deviation on the heater performance of position, the temperature sensor self of bucket temperature inside sensor, is to be difficult to realize accurately oven dry automatically.
Particularly using under the situation of fixing aridity judgment value, as shown in Figure 5, owing to be not all to keep consistency ground that aridity is judged to all laundry amounts, the therefore very difficult drying stroke that realizes exactly.
For instance, when to carry out the target aridity be 90% drying stroke, if under the situation that aridity judgment value Δ is fixed on " 50 ", dry, on actual that time point that has reached 90% aridity, aridity judgment value Δ can be different along with the difference of laundry amounts so.
That is to say that aridity judgment value Δ is " 25 " in laundry amounts during for 1kg, laundry amounts is " 40 " during for 2kg, and laundry amounts is " 55 " during for 4kg, therefore says and can't realize exactly that in this case oven dry is responded to automatically.
Here used aridity judgment value Δ is decimal data (decimal data).
As top said, can't realize exactly situation as shown in Figure 6 can occurring under the situation of oven dry induction automatically, promptly can't obtain to satisfy the aridity distribution that the user requires.
As shown in Figure 6, in each corresponding drying stroke, in a certain interval (block) (part that solid vertical line is represented), 1,2,3 the point (1 → 1.0kg that is marking off according to laundry amounts, 2 → 2.0kg can realize drying accurately on 3 → 4.5kg).In a single day even so, but broken away from above-mentioned interval, just can't realize drying accurately.
As shown in Figure 6, when laundry amounts more after a little while, even utilize fixedly aridity judgment value Δ, also can in each drying stroke [Dry, Strong, Damp, LTD (Low Temperature Dry)], reach desired aridity, but along with the increase of laundry amounts, it is more and more lower that aridity can become.

The specific embodiment
Shown in Fig. 7 a to Fig. 7 c, control method of automatic drying of the present invention can be divided into following several stages substantially: the stage of temperature data stabilisation; The temperature data that settles out is given amplification, thereby enlarge the stage of resolution capability; To detect the required time of aridity judgment value Δ under difference oven dry pattern is benchmark, calculates the stage of appending drying time and appending oven dry.
In the following description, laundry amounts does not mean " laundry amounts of considering moisture content " merely, and it has also considered that the factor of cloth (because the cloth difference, moisture content is also different) come in simultaneously.
In addition, in the following description, " Δ T " refers to the temperature difference between each temperature sensor that calculates before the mean value in respective bins, " Avg Δ T " refers to the average value in interval that calculates in respective bins, " Δ " refers to the final aridity judgment value that calculates by the stabilisation stage.
Each temperature difference Δ T is the difference between the temperature sensor of the temperature sensor of Tube Temperature Sensor TA1 and bucket temperature sensor Ttub; Wherein above-mentioned Tube Temperature Sensor TA1 is positioned at the pipeline that has formed the oven dry circulation canal; Above-mentioned bucket temperature sensor Ttub then is positioned at bucket inside, and it can detect the temperature that changes along with the carrying out of oven dry.
Another method is: each temperature difference Δ T is the difference between the temperature sensor of the temperature sensor of the 1st temperature sensor TA1 and the 2nd temperature sensor TA2; Wherein above-mentioned the 1st temperature sensor TA1 is positioned at the upper end of the pipeline that has formed the oven dry circulation canal; Above-mentioned the 2nd temperature sensor TA2 then is positioned at the lower end of pipeline, and it can detect the temperature that changes along with the carrying out of oven dry.
Be that the center describes with the method for utilizing Tube Temperature Sensor TA1 and bucket temperature sensor Ttub below.
The control method of automatic drying of the 1st embodiment of the present invention is shown in Fig. 7 a, if begin oven dry (S701), that time point of variation more than the certain value will appear from the temperature sensor of Tube Temperature Sensor TA1 or bucket temperature sensor Ttub in micro computer so, or after begin to dry through that time point of a period of time begin, with some cycles accounting temperature difference Δ T (Δ T=TA1-Ttub) (S702).
Here preferably in the following ways: after beginning oven dry, begin that stable time point (promptly beginning to supply that time point of the cooling water that is used to dry) beginning from the detection action of temperature sensor, aridity judgment value Δ is revised and calculated to temperature data.
Next the motor swing circle T (S703) that changes of trace routine (program), if the motor swing circle has repeated set point number (S704), so just calculate the average value in interval Avg Δ T (S705) of each temperature difference Δ T in the respective bins, wherein above-mentioned each temperature difference Δ T utilizes the data of calculating and storing at respective bins interior conduit temperature sensor TA1 and the detected temperature data of bucket temperature sensor Ttub.
That time point that why will allow micro computer finish at the motor swing circle calculates (averaging) average value in interval Avg Δ T, is in order to reduce the positive and negative swing circle effect that the temperature data value is subjected to motor to greatest extent.
Fig. 8 is used for calculating the mean value calculation cycle of the aridity judgment value Δ among the present invention and the curve map of the relation of motor between the cycle.
As an embodiment, as shown in Figure 8, is original 40sec (16sec just changes-4sec stops-16sec counter-rotating-4sec stops) a motor swing circle, and having become 30sec (12sec just changes-3sec stops-12sec counter-rotating-3sec stops) is a motor swing circle.
If in micro computer, the cycle of computation interval mean value Avg Δ T is made as 60sec, so just be equivalent to per 2 motor swing circles and calculate 1 average value in interval Avg Δ T, and the method for calculating 1 average value in interval Avg Δ T by this per 2 motor swing circles can improve data stability.
If calculate average value in interval Avg Δ T and used as aridity judgment value Δ by said method, so will be as shown in Figure 9, the phenomenon of data dithering reduces, and presents stable status.
More than be an embodiment, in addition, also can set the motor swing circle for different numerical value (not being 30sec), simultaneously cycle and the above-mentioned motor swing circle of micro computer computation interval mean value Avg Δ T are consistent, like this can obtain to stablize the effect of data equally.
Next step will be used as aridity judgment value Δ to the average value in interval Avg Δ T that tries to achieve by said method, and itself and a reference value of setting according to corresponding oven dry pattern are compared (S706).
If above-mentioned comparative result (S707) is not for reaching the pairing a reference value of selected oven dry pattern, so just recomputate the temperature difference Δ T (Δ T=TA1-Ttub) between the temperature sensor of Tube Temperature Sensor TA1 and bucket temperature sensor Ttub and it is stored (S702), repeat the above-mentioned stage then by micro computer.
If in above-mentioned comparison phase, comparative result so just finishes drying stroke (S708) for satisfying the requirement of selected oven dry pattern.
Here, above-mentioned average value in interval Avg Δ T is used as aridity judgment value Δ, and in the stage that itself and a reference value of setting according to corresponding oven dry pattern are compared, if aridity judgment value Δ is higher than the situation of a reference value and has occurred continuously 2 times, so just can be judged as and reached desired aridity.Do like this is in order to improve the accuracy that aridity is judged.
For the aforesaid autocontrol method that has adopted the 1st embodiment of the present invention, owing to can on the basis of considering the motor swing circle, calculate the average value in interval Avg Δ T of respective bins, and the average value in interval Avg Δ T that will draw thus is as aridity judgment value Δ, therefore can remove the inaccurate factor that the temperature data shake is brought, thereby realize fully to satisfy the automatic oven dry control that the user requires.
Adopt the autocontrol method of the 2nd embodiment of the present invention as described below, also comprised the amplification stage, can improve the resolution capability of the judgment value that is used for judging aridity by this stage.
At first, shown in Fig. 7 b, if begin oven dry (S801), that time point of variation more than the certain value will appear from the temperature sensor of Tube Temperature Sensor TA1 or bucket temperature sensor Ttub in micro computer so, or after begin to dry through that time point of a period of time begin, with some cycles accounting temperature difference Δ T (Δ T=TA1-Ttub) (S802).
Next the motor swing circle T (S803) that changes of trace routine (program), if the motor swing circle has repeated set point number (S804), so just calculate the average value in interval Avg Δ T (S805) of each temperature difference Δ T in the respective bins, wherein above-mentioned each temperature difference Δ T utilizes the data of calculating and storing at respective bins interior conduit temperature sensor TA1 and the detected temperature data of bucket temperature sensor Ttub.
That time point that why will allow micro computer finish at the motor swing circle calculates (averaging) average value in interval Avg Δ T, is in order to reduce the positive and negative swing circle effect that the temperature data value is subjected to motor to greatest extent.
For the resolution capability (resolution) that improves the aridity judgment value, next to carry out the average value in interval Avg Δ T amplification of will try to achieve, thereby obtain the stage (S806) of aridity judgment value Δ.
Certainly, be to repeat to draw in n time the interval corresponding to computation interval through the average value in interval Avg Δ T of amplification here with the motor swing circle.
For example, when the motor swing circle is 30sec, correspondingly computation interval can be set at 60sec, and calculate the mean value of the Δ T that during 60sec, is stored continuously, then with this mean value amplification.
Former, because the shake of temperature data is bigger, if therefore carry out amplification in this case, the inaccuracy of data also can be corresponding extended so.But in the present invention, because data are in stable state, thereby not only can carry out amplification, and can improve the resolution capability of data, thereby guarantee reliability by amplification.
For instance, when micro computer is discerned the output of 0～5V with the numerical value of 8 bits, this numerical value can be divided into 0～255 and discern, but before, no matter aridity judgment value Δ is " 5 " still is " 5.9 ", and micro computer all can be identified as it " 5 ".
[table 1]
| ADC Decimal | During 4 times of amplification | During 3 times of amplification | |
| Damp | Δ5 | Δ20 | Δ15 |
| Dry | Δ8 | Δ35 | Δ25 |
| Strong | Δ13 | Δ50 | Δ40 |
As can be seen from Table 1, when aridity judgment value Δ is carried out amplification, for example, will become " 20 " 4 times of 5.00～5.24 amplification; 4 times of 5.25～5.49 amplification, will become " 21 "; 4 times of 5.50～5.74 amplification, will become " 22 "; 4 times of 5.75～5.99 amplification, will become " 23 ", like this, micro computer just can be distinguished and be discerned these data, therefore can judge aridity exactly by the stage of further segmentation.
As mentioned above, can amplify m method doubly by average value in interval Avg Δ T with ADC decimal data (decimal data) form, obtain the average value in interval through amplification, and in this case, the m before the number that micro computer can recognition data can be increased to doubly.
Next to compare (S807) by said method aridity judgment value Δ that obtains and a reference value of setting according to corresponding oven dry pattern.
If above-mentioned comparative result (S808) is not for reaching the pairing a reference value of selected oven dry pattern, so just by micro computer recomputate between the temperature sensor of Tube Temperature Sensor TA1 and bucket temperature sensor Ttub temperature difference Δ T (Δ T=TA1-Ttub) (S802), repeat the above-mentioned stage then.
If in above-mentioned comparison phase, comparative result so just finishes drying stroke (S809) for satisfying the requirement of selected oven dry pattern.
Similarly, above-mentioned average value in interval Avg Δ T is used as aridity judgment value Δ, and in the stage that itself and a reference value of setting according to corresponding oven dry pattern are compared, if aridity judgment value Δ is higher than the situation of a reference value and has occurred continuously 2 times, so just can be judged as and reached desired aridity.Do like this is in order to improve the accuracy that aridity is judged.
For the aforesaid autocontrol method that has adopted the 2nd embodiment of the present invention, not only can on the basis of considering the motor swing circle, calculate the average value in interval Avg Δ T of respective bins, and the average value in interval Avg Δ T that will draw thus shakes the inaccurate factor of being brought as aridity judgment value Δ thereby remove temperature data; And the aridity judgment value can be given amplification, thereby make micro computer be segmented and to discern, therefore can realize fully to satisfy the automatic oven dry control that the user requires it.
Adopt the characteristics of the control method of automatic drying of the 3rd embodiment of the present invention to be: to calculate earlier that to begin to reaching for the first time with the aridity judgment value from that time point of oven dry beginning be the needed time till that time point of dryness fraction of standard, and be that benchmark appends oven dry with this section period.Therefore this method can all satisfy the requirement of its corresponding oven dry pattern at all laundry amounts.
At first, shown in Fig. 7 c, if begin oven dry (S901), that time point of variation more than the certain value will appear from the temperature sensor of Tube Temperature Sensor TA1 or bucket temperature sensor Ttub in micro computer so, or after begin to dry through that time point of a period of time begin, with some cycles accounting temperature difference Δ T (Δ T=TA1-Ttub) (S902).
Next the motor swing circle T (S903) that changes of trace routine (program), if the motor swing circle has repeated set point number (S904), so just calculate the average value in interval Avg Δ T (S905) of each temperature difference Δ T in the respective bins, wherein above-mentioned each temperature difference Δ T utilizes the data of calculating and storing at respective bins interior conduit temperature sensor TA1 and the detected temperature data of bucket temperature sensor Ttub.
That time point that why will allow micro computer finish at the motor swing circle calculates (averaging) average value in interval Avg Δ T, is in order to reduce the positive and negative swing circle effect that the temperature data value is subjected to motor to greatest extent.
For the resolution capability (resolution) that improves the aridity judgment value, next to carry out amplification, thereby obtain the stage (S906) of aridity judgment value Δ average value in interval Avg Δ T.
Former, because the shake of temperature data is bigger, if therefore carry out amplification in this case, the inaccuracy of data also can be corresponding extended so.If but as the present invention, be in stable state in data and carry out amplification, just can improve the resolution capability of data, thereby guarantee reliability.
Next to compare (S907) by said method aridity judgment value Δ that obtains and a reference value of setting according to corresponding oven dry pattern.
If above-mentioned comparative result (S908) is not for reaching the pairing a reference value of selected oven dry pattern, so just by micro computer recomputate between the temperature sensor of Tube Temperature Sensor TA1 and bucket temperature sensor Ttub temperature difference Δ T (Δ T=TA1-Ttub) (S902), repeat the above-mentioned stage then.
If in above-mentioned comparison phase, having arrived with aridity judgment value Δ under selected oven dry pattern is the drying requirement of benchmark, so just calculate that time point that begins from oven dry and begin the needed time till now, and determine to append drying time (S909) as benchmark.
Below to append drying time determine described in detail.
As shown in figure 10, appending drying time and reaching the required time of aridity the 1st time is linear relationship, and it is fixed therefrom therefore appending drying time.This is because if append drying time and above-mentioned required time is not a linear relationship, but the step form occurs, and jumping will appear in aridity numerical value on appropriate section so, thereby can't realize accurate oven dry.
Why will will utilize fixing aridity judgment value Δ as top said, also will append oven dry again after the 1st time reaches aridity simultaneously, it the reasons are as follows described.
When drying automatically, want to carry out aridity exactly and judge that this setting for aridity judgment value Δ is very difficult at all laundry amounts.
For instance, if wish that the dryness fraction that reaches is 90%, in actual process of drying, the time point when reaching 90% aridity can be different along with the difference of laundry amounts so.Different laundry amounts reaches the time point difference of 90% aridity under identical oven dry pattern, just means that also the Δ value is also different.
Like this, if utilize fixedly aridity judgment value Δ to dry, under the situation that reaches aridity judgment value Δ, laundry amounts is big more so, and aridity can be low more.
As shown in figure 10, appending drying time is to determine like this, for instance, if under standard oven dry pattern, the time point that reaches aridity judgment value Δ is to begin through that time point behind the 60min from oven dry, and Ci Shi the drying time that appends is exactly 25min so.
Promptly along with the x axle reach the aridity increase of required time, the drying time that appends of y axle also is the linear trend that increases.
X axle representative is from beginning to dry to reaching required drying time (Drytime) till the aridity judgment value Δ, appends drying time (Add time) when the y axle represents curve corresponding with some values of x axle.
Why will be as top said, increase by one with the drying time that appends that reaches the sexual intercourse of aridity required time retention wire for the 1st time, even be because under the identical situation of laundry amounts,, reach that fixedly the required time of aridity judgment value Δ also can be different along with the difference of cloth.
For example, when the cloth of washings belongs to difficult oven dry and so on, fixedly the required time of aridity judgment value Δ will be long owing to reach, thereby append the also corresponding lengthening of need of drying time, because only in this way could reach the desired oven dry degree of user exactly.
If determined to append drying time, so next append oven dry (S910) in the drying time in above-mentioned definite appending exactly according to the rule of example shown in Figure 10.
Carried out the corresponding time (S911) if append oven dry, so just finished whole drying stroke (S912).
Do not append the interval that oven dry also can reach desired oven-dried condition even have one in addition, the situation in this is interval all belongs to the fixedly required short situation of time of aridity judgment value Δ that reaches.
This time is being decided to be under the situation of fiducial time,, is not so just appending oven dry if it is short this fiducial time to reach the required time ratio of fixing aridity judgment value Δ.
Promptly as shown in figure 10, under " Damp " oven dry pattern,, so just do not append oven dry if reach the required time of fixing aridity judgment value Δ in 20min; And under " Strong " and " Dry " oven dry pattern, then do not append oven dry with interior at 30min.
Difference is because will reach the drying regime of the best when allowing whole drying course finish on the basis of considering cloth and moisture content along with the difference of oven dry pattern why will to allow the fiducial time of not carrying out appending oven dry.
As can be seen from Figure 11, under each corresponding oven dry pattern, (3 → 4.5kg) all in certain interval (part that solid vertical line is represented) for 1 → 1.0kg, 2 → 2.0kg for 1,2,3 each points of telling according to laundry amounts.
This means that aridity judgment value Δ carries out the 1st aridity judgement by utilizing fixedly, implement to append the method for oven dry then according to its result, can all realize drying accurately all laundry amounts.
Promptly be regardless of on a small quantity still in a large number,, can be issued to desired aridity at each oven dry pattern [Dry, Strong, Damp, LTD (Low Temperature Dry)] at used laundry amounts.
In addition, autocontrol method according to aforesaid the 1st, 2,3 embodiment of the present invention, in the process that drying stroke is carried out, if the oven dry time of carrying out has reached oven dry binding hours (230min), or the some temperature sensor values in the temperature sensor have surpassed the oven dry limits value, have for example surpassed 180 (ADC decimal data), and so no matter which kind of degree is aridity reached, for the purpose of safety, all to finish drying stroke at once.
Aforesaid control method of automatic drying of the present invention can be in automatic drying roller washing machine and roller dryer, by the following method, be about to be used for temperature data that aridity judges give stabilisation, by amplification improve resolution capability, in order all to realize drying accurately the method for determining to append drying time and implementing to append oven dry to all laundry amounts, improve the accuracy of drying stroke.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
