Below by Fig. 1～Fig. 3 the mode of operation that tumbling-box washing machine carries out is described under the control of above-mentioned control device 16.
During laundry, open gate 7 earlier, in swing roller 1, drop into washings, add washing powder from the washing powder input port (not shown) that is located on the water entering section 15; Then, press " power supply is opened " button 17f on the guidance panel 33 shown in Fig. 3, connect power supply, select suitable operator scheme by model selection button 17d by the kind of washings, press the instruction that startup/pause button 17e input operation begins, control device 16 promptly begins to operate control.The operation of tumbling-box washing machine is carried out according to the order of washing operation, rinsing operation, dehydrating operations basically.Be provided with under the occasion of clothes drying function, the user can also freely select whether to implement the drying operation.
After the operation beginning, control device 16 at first sends the control instruction that drives swing roller 1 rotation with predetermined rotational speed to drive circuit 22, to detect the washings amount of putting in the swing roller 1.Under the driving of drive circuit 22, drum drive motor 5 makes swing roller 1 rotation, detects washings amount according to drum drive motor 5 is that be subjected to the corresponding load condition of washings amount by clothing amount detecting device 27.
Particularly, drum drive motor 5 is made of dc brushless motor, drive circuit 22 as shown in Figure 2 like that the switch element 23a～23f in the frequency converter 23 is carried out conduction and cut-off control, thereby to the 1st～the 3rd winding 5a, 5b, the 5c of 3 phase windings of the stator (not shown) that constitutes drum drive motor 5 control of switching on.
Mains supply 28 supplies in the frequency converter 23 after being rectified into direct current by diode bridge rectifier circuit 29, choke coil 30, smmothing capacitor 31.Because the load that drum drive motor 5 is subjected to is directly proportional substantially with its input current, the both end voltage of the resistor 25 that Weight detector 24 is connected in series according to the DC power-supply circuit with frequency converter 23 can be detected the input current value of drum drive motor 5 by current detection circuit 26, therefore, clothing amount detecting device 27 can detect the washings amount of putting into the swing roller 1 from above-mentioned input current value.Because clothing amount detecting device 27 detected washings amount information will also will use in control operation described later, therefore stored in the memory (not shown) that is located in the control device 16 earlier.
Next, control device 16 is opened the control instruction of water intaking valve 12 to load drive device 20.After water intaking valve 12 is opened, add water by the water supply hose 12a that links to each other with water inlet member 15, the water of adding mixes with the washing powder of putting in the water inlet member 15 on one side, Yi Bian join in the steel ladle 3.Amount of water in steel ladle 3 is corresponding and controlled by adding water time set Cheng Yuyi amount detecting device 27 detected washings amounts, and the water levels in the steel ladle 3 are then detected by the condensate tank of dehumidifier 19 that is located in the steel ladle 3.When reaching predetermined water level, send the water level detecting signal of regulation from condensate tank of dehumidifier 19 to control device 16,16 of control device cut out the control instruction of water intaking valve 12 to load drive device 20 outputs, and making into, water stops.Simultaneously, be added to the washings that the water in the steel ladle 3 can be installed in the swing roller 1 by the through hole 2 that is located on the swing roller 1 and suck, the water levels in the steel ladle 3 may descend, so need replenish water inlet.The mode of operation of replenishing water inlet is with top the same.
Through after the above-mentioned control operation, just can begin to carry out the washing operation step.The concrete operations situation is, control device 16 is sent the control instruction that is driven swing roller 1 rotation by drum drive motor 5 in drive circuit 22, the 1st stirring control operation that execution is following: promptly drive swing roller 1 earlier and rotate official hour towards positive veer with predetermined rotational speed, the driving of in official hour, stopping the rotation then, then towards reverse directions rotation official hour, stall official hour then; Above-mentioned operation constitutes a circulation, and so needed time that circulates in constantly repeats to carry out.Above-mentioned regulation rotary speed for making washings the rotary speed of following motion takes place: promptly the washings a plurality of locational stirring thrust 6 that can be arranged on the internal face of swing roller 1 hooks, along with being rotated on the direction of rotation of swing roller 1 is taken up, fall above on the height and position of centrifugal force in deadweight again.
By washings being mentioned, throw the effect of beaing washing, and constantly repeat such operation, can produce the clean effect that the dirt on the washings that will suck washing powder solution is washed off being applied with on the washings.In addition, therefrom extracted out, can also be produced the effect that makes washings generation place-exchange owing to having only in the washings that is deposited in together with stirring thrust 6 contacted clothings.When the rotary speed of swing roller 1 is slower than predetermined rotational speed, stirring thrust 6 just can not mention washings, conversely, when the rotary speed of swing roller 1 is faster than predetermined rotational speed, centrifugal action will increase, and the situation that can not lean on its deadweight to fall can take place the washings that is raised.In addition, commutate, can also suppress to take place in the washings wrapping phenomena, carry out place-exchange effectively by the direction of rotation that makes swing roller 1.
Be subjected to being contained in the influence of the washings amount in the swing roller 1 owing to washings being mentioned, throw the effect of beaing washing that produces, therefore, better control method is above-mentioned regulation rotary speed to be controlled to washings change.Particularly, can resemble foregoing after clothing amount detecting device 27 detects the washings amount that is contained in the swing roller 1, testing result is stored; When the washings amount than predefined ormal weight for a long time, then predetermined rotational speed is reduced by control device 16.
On the other hand, when the washings amount of being advanced by storage than predefined ormal weight after a little while, 16 of control device increase predetermined rotational speed.Though repeating the 1st above-mentioned stirring control operation in needed wash time can reach while making washings that the effect that transposition is washed take place, but, if in the needed time, carry out the 1st stirring control operation earlier, carry out the 2nd stirring control operation more afterwards, can reach better effect.
The specific operation process of the 2nd above-mentioned stirring control operation is as follows.At first drive swing roller 1 fast regulation rotary speed when stirring control operation and on positive veer, rotating official hour than the 1st; Afterwards, the driving of stopping the rotation at the appointed time; Then, on reverse directions, be rotated driving at the appointed time with identical regulation rotary speed when just changeing; The driving of in official hour, stopping the rotation again, above-mentioned control operation constitutes a circulation, and such circulating in the needed time constantly repeats.The above-mentioned the 2nd regulation rotary speed that stirs in the control operation is set to such rotary speed: be adjacent on the inner barrel wall of swing roller 1 under the action of centrifugal force that washings is produced when swing roller 1 rotation.
By washings is adjacent on the inner barrel wall of swing roller 1, amass block washings also tensible become deployed condition.When stopping through rotation after the stipulated time, the washings that forwards swing roller 1 top to can separate with the inner barrel wall of the swing roller 1 that rotates along with inertia and then fall.By making washings carry out this motion of stretching, falling again then because of being adjacent to, can make washings that transposition and change of shape take place, beat the effect of washing and also can bring into play effectively.
By in the needed time mutual continuously carry out the above-mentioned the 1st and the 2nd each stir control operation, front and back position will take place and exchange in washings swing roller 1 in, can produce simultaneously motion mode different beat cleaning function.Like this, can not descend yet, can be applied with all washings and clean effect uniformly even swing roller 1 is obliquely installed washing (-)off properties.
After above-mentioned washing operation finished, control device 16 export the control instruction of opening draining valve 11 in load drive device 20, carried out the draining control operation of the dirty washings in the steel ladle 3 through drainage channel 10 discharges.After washing step, control device 16 is exported in drive circuit 22 and is made drum drive motor 5 rotate, make washings contained in the washings to deviate from control instruction at a high speed, implements dehydrating operations.
Finish after the dehydrating operations of stipulated time, control device 16 cuts out draining valve 11, and then opens water intaking valve 12, adds new water in steel ladle 3, begins to carry out the rinsing operation.In the rinsing operating process, Yi Bian also make swing roller 1 constantly just change, reverse, Yi Bian carry out stirring operation.Wherein, by resembling in the above-mentioned washing step, carry out the 1st and stir control operation and/or the 2nd stirring control operation, can make washings occurrence positions exchange equally, make and beat cleaning function and affact equably on all washings, thereby can realize not having the rinsing operation of rinsing inequality.
The detail operations situation of each operational phase has been shown among Fig. 4.After washing step, implement 2 rinsings operation usually, after each rinsing operation, all carry out dehydrating operations, make water contained in the washings realize dehydration.Wherein, the dehydrating operations that carries out after the 2nd rinsing operation is formal dehydration stroke.That is to say, comprise the drain operation in the above-mentioned washing step, performed here dehydrating operations all is to make swing roller 1 rotation at a high speed after draining, thereby moisture is deviate from from washings.For the dehydrating operations in each stroke is carried out reliably, need make washings become the state that is adjacent to equably on the inner barrel wall of swing roller 1, thereby make water contained in the washings under action of centrifugal force from steel ladle 3 via through holes 2 throw away.
If washings is under the bias state in swing roller 1, not only dehydrating operations can not successfully carry out, and the skew of position of centre of gravity makes swing roller 1 wave when rotated easily and vibrates, and therefore when dehydrating operations begins, carry out the starting process of dehydrating operations.
Use Fig. 5,6 that control procedure in the dehydrating operations is described below, in proper order wherein the 1st～the 3rd control procedure is described.
The 1st control procedure of the start-up function in the dehydrating operations of being carried out by control device 16 has been shown among Fig. 5.Wherein, institute's target sequence number S1, S2 in each step among the figure ... be the step number in the control procedure, consistent with hereinafter appended sequence number.
After dehydrating operations begins, at first set the initial decision content (S1) be used to judge the regulation that laundry balancing is whether good, and will judge number of repetition initialization (N=1) (S2); Then, make drum drive motor 5 accelerate to the 1st regulation rotary speed (as 90 rev/mins) gradually (S3).Make drum drive motor 5 accelerate to data then detected and that be stored in the control device 16 of used time of the 1st regulation rotary speed gradually and advance the control of clothing amount row according to clothing amount detecting device 27.
When the washings amount is more, as shown in Fig. 6 (a), make the rotary speed of drum drive motor 5 accelerate to the 2nd regulation rotary speed (as 40 rev/mins) at the 1st stipulated time t1, and before the 2nd stipulated time t2, keep this speed, between the 2nd stipulated time t2 to the 3 stipulated time t3, accelerate to the 1st regulation rotary speed then; When the washings amount is less, shown in Fig. 6 (b), then carry out the control to time (t2～t3 ') shortening of the time t3 ' that reaches the 1st regulation rotary speed with the 2nd stipulated time t2.Adopt after this control, the centrifugal force that acts on the washings will become greater than gravity, and washings becomes the state that is adjacent on the inner barrel wall of swing roller 1 easily.
If the user does not change (S4) to decision content setting situation, then make decision content keep original start numerical value (S1) constant, the changing value and the setting value T of detected rotary speed compared (S6).If less than setting value T, represent that then washings is adjacent to equably on the inner barrel wall of swing roller 1, will judge that in the laundry balancing decision process balance is good, control device 16 makes drum drive motor 5 dehydrating operations (S11) of rotation at a high speed with execution, makes washings realize dehydration.
Above-mentioned laundry balancing judgement is to be undertaken by the inhomogeneous situation of rotation that detects swing roller 1.Under drum drive motor 5 situation about constituting by dc brushless motor like that as shown in Figure 2, stator is provided with position detecting device 21a, 21b, the 21c that is made of Hall element, the electric angles that these position detecting devices 21a, 21b, 21c have 120 degree between mutually and face the permanent magnet (not shown) that is located on the rotor (not shown) at interval.When rotor 1 rotation, the magnetic field of described permanent magnet is detected by position detecting device 21a, 21b, 21c, produces to have 120 degree electric angles pulse signal at interval, and such pulse signal is imported in the control device 16.
Therefore, rotary speed at swing roller 1 is keeping under the state of predetermined rotational speed, if detecting the pulse of position detecting device 21a, 21b, 21c does not export with predetermined distance, then can decision making: produced the uneven state of rotation in the swing roller 1, that is washings fails to be adjacent to well on inner barrel wall, and laundry balancing is in not good state.
Therefore, be set at the laundry balancing decision content, can detect the washings non-equilibrium state in the swing roller 1 by excursion with the rotary speed of drum drive motor 5.In practical operation, detect the uneven method of rotation and be 31 in were mutually measured mutually.In detail, with position detecting device 21a is example, during swing roller 1 rotates a circle, input pulse can be counted 4 times, to be designated as T1, T2, T3, T4 (not shown) respectively to the timing result of this input pulse, the rotary speed that converses is designated as R1, R2, R3, R4 respectively.Under the occasion of uneven without spin in cylinder, spin stabilization, R1=R2=R3=R4=90 rev/min; And having under the uneven occasion of rotation, then may (for example) 87 rev/mins～93 rev/mins ± 3 rev/mins scope in variation.This excursion is big more, and expression rotation inequality is big more, and the laundry balancing state is also just poor more.
In the process that changing value and setting value T with rotary speed compare (S6), setting value T at first is set to 3 rev/mins of initial decision contents, therefore, when the changing value of rotary speed is judged as 3 rev/mins or when above, control device 16 will make swing roller 1 stop the rotation (S7).Then, judge whether number of repetition N reaches the 1st stipulated number (as N=16) (S8),, then on judgement number of repetition N, add 1 (S9), return then, restart starting process from step S3 if do not reach stipulated number.
After repeating aforesaid operations, if judge that in step S6 laundry balancing is good, then carry out dehydrating operations (S11) down in the dehydration rotary speed (as 900 rev/mins) of regulation, washings is dewatered.
By repeating start-up function, can change the state of clothing, washings is adjacent to easily on the inner barrel wall of swing roller 1.But, if control device 16 finds to judge that number of repetition N has reached the also not improvement of state of stipulated number (as N=16), washings, then carry out abnormal alarm by modes such as electronic audio or sound phonosynthesis, the prompting user unties the winding (S10) in the washings.Then, the user who also has is after seeing that washing machine repeatedly repeats above-mentioned sequence of operations, can think whether fault has taken place washing machine, may be more worried, even therefore they wish more or less to vibrate, the sound that dewaters is a bit big, also to reach the dehydration rotary speed (S11) of regulation as soon as possible.
In order to satisfy such demand, can take following scheme.That is, by carry out in above-mentioned repetitive operation in the process will (for example) Fig. 3 rinsing number of times input setting device 17b pin the several seconds continuously, initial decision content is changed, become new decision content.Judge that at step S4 decision content sets when change has taken place, then in step S5, will set value T and change into bigger 5 rev/mins of permissible range, like this, in step S6, just can realize acceleration easily for 3 rev/mins compared with initial decision content.At that rate, under user's approval, even vibration and dehydration sound more or less increase also decision content is changed, the permissible range that laundry balancing is judged strengthens, and dehydrating operations is preferentially carried out, and the phenomenon of dehydrating operations Halfway Stopping just can be eliminated.
In addition, in order to prevent maloperation, the input setting device that above-mentioned change decision content is set also can adopt the scheme of a plurality of existing switches of pressing Fig. 3 simultaneously.In addition, can also in control device 16, memory be set, like this, not only can in this operating process, change decision content, and can automatically use decision content after the change since next time.
In addition, also can resemble shown in Fig. 7 be provided with that dehydration is uneven judges change-over switch 17h, as the special use input setting device that changes decision content.Like this, not only the user uses more conveniently, shows the changed display unit (promptly judging grade display unit 18h) of this situation of decision content if be provided with simultaneously again, can make operational circumstances very clear.
Permissible range is big more, and dehydrating operations will easy more starting, but vibration and sound when dewatering also will be big more.Owing to allow that for vibration and sound grade, service behaviour, dehydration degree of priority are different because of the user, so the decision content (S6) after changing can be arranged to a plurality of grades, as grade 1 is T=5 rev/min, grade 2 is T=7 rev/min, grade 3 is T=9 rev/min, and the user can freely be selected.Like this, the user can select to use according to the wish of oneself, thereby can realize flexible processing.
In addition, for initial judgement setting value T (3 rev/mins), can also (for example) grade 1 be made as T=1 rev/min, grade 2 is made as T=5 rev/min, and grade 3 is made as T=7 rev/min.Like this, under the occasion of selecting grade 1, on the contrary permissible range is reduced, thereby can suppress vibration in the dehydrating operations and sound littler.
In sum, tumbling-box washing machine of the present invention can shorten the laundry balancing of at first carrying out and judge the required time in dewatering operation course, thereby can shorten wash time and dehydrating operations is carried out reliably, therefore, can be useful in the various devices such as the decontaminating apparatus that adopts one-sided brace type swing roller, clothes-drying device.
