In addition, load driving part 31 is connected with control part 30, by load driving part 31, respectively to rotary drum electrical motor 20, set fan motor 35 and dry in the above-mentioned heating hair-dryer with heater 37, the water heater 36 that the water of the inside that is stored in water jacket 10 is heated, the feed water valve 38 that control is supplied water in water jacket 10, control is from the draining valve 39 of the draining in the water jacket 10, be arranged at the inside of cylinder locking mechanism portion 21, and the torque motor 21a of the drive source of cylinder locking and its releasing is carried out in conduct, be arranged at cover lock and decide the inside of portion of mechanism 23, and cover lock is decided and the actions such as solenoid 23a of the drive source of its releasing are controlled respectively as carrying out.In addition, control part 30 send to show signal to display part 5c, so that carry out with the corresponding demonstration of the operation of operating portion 5a, be used to notify running to carry out the demonstration of situation, makes the buzzer 5d action that pipes, so that carry out certain circular to the user.

Then, by Fig. 6 the laundry of this tumbling-box washing machine, the summary of dry action are described.Fig. 6 is the flow chart of the flow process of the standard stroke of this tumbling-box washing machine of expression.

If the user is with the washed inside that is received in cylinder 13, by operating portion 5a turn round the beginning operation, then control part 30 is opened feed water valve 38, the washing agent liquid of ormal weight is stored in the inside of water jacket 10, head roll motor 20, rotary speed according to the rules makes cylinder 13 rotations, thus, adopt the washing stroke (step S1) of washing agent liquid.Then,, discharge the water in the water jacket 10, make cylinder 13 rotations at high speed, thus, carry out centre dehydration stroke (step S2) by draining valve 39.

Then, in the front and back of centre dehydration stroke, (step S3～S5), behind the 2nd clear water rinsing stroke, the stroke that dewaters is extruded the water (step S6) that comprises in washed to carry out 2 times clear water rinsing stroke.Then, drying is switched on heater 37, drive fan motor 35, when will adding hot-air and delivering to the inside of water jacket 10, rotary speed makes cylinder 13 rotations according to the rules, stirs washed, thus, carries out dry trip (step S7).

If the dry operating time of regulation finishes, then basic stroke finishes.But, if after dry trip finishes, same as before with the washed inside that is positioned over cylinder 13, then cause wrinkling, and washed hardening.Therefore, wrinkling in order to prevent, and handle washed with the advantages of good skin sense of touch, take out to the user before washed during, carry out the rotation of cylinder 13 and static by alternate repetition, carry out soft treatment stroke (step S8).But, long if the soft treatment stroke continues, because the waste of electric power increases, even so in from cylinder 13, taking out under the washed situation, still tie the occasion of coming here the soft treatment actuation time (being 120 minutes) of regulation, whole actions is finished fully, cut off the electricity supply.

Below with reference to Fig. 7 and Fig. 8, the control method of the rotary drum electrical motor 20 during to the soft treatment stroke in this tumbling-box washing machine is described.The cylinder of Fig. 7 during for expression soft treatment stroke be static/the program oscillogram in 1 cycle of rotation, and Fig. 8 is the figure of the control parameter of expression this moment.

As shown in Figure 7, according to ta quiescent time, with cylinder 13 remain on inactive state during, according to the mode that can open top cover 2, remove cover lock fixed (that is, cover lock decide detection signal be abort state).In addition, at this moment,, carry out cylinder locking (that is, the cylinder lock detecting signal is a persistent state) according to cylinder 13 non-rotary modes.If ta quiescent time of regulation finishes, then control part 30, locks lid surely with solenoid 23a energising cover lock, so that stop opening of top cover 2 by load driving part 31.Consequently, to decide detection signal lasting from ending to become for cover lock.Carry out cover lock fixed after, this time, driving torque motor 21a is so that remove the cylinder locking.If by this action, remove the cylinder locking, then the cylinder lock detecting signal is from continuing to become termination.

Then, control part 30 is according to passing through load driving part 31, and head roll motor 20, cylinder 13 are according to the rotary speed of about 50rpm, and the mode of the rotational time tb of rotation regulation is controlled.If rotational time tb finishes,, adjust the position (speaking by the book is the position of rotor 202) of cylinder 13 then by head roll motor 20, so that carry out the cylinder locking, if cylinder 13 arrives the latched position of regulation,, carry out the cylinder locking then by head roll motor 21a.Consequently, the cylinder lock detecting signal becomes lasting from ending.In addition, once more cover lock is switched on solenoid 23a surely, thus, it is fixed to remove cover lock, can open top cover 2.

In the soft treatment stroke, said procedure repeatedly, start-up operation until the key 5b that uncaps, but as shown in Figure 8, though the rotational time tb of this program (10 seconds), and the rotary speed (50rpm) of the cylinder 13 of this moment does not change, yet, quiescent time, ta was according to corresponding to finishing the elapsed-time standards t that (that is, the soft treatment stroke begins) rises from dry trip, and the mode that is classified to increase is set.

In the rotational time tb of cylinder 13, stir washed, follow this situation, wrinkle are drawn back, and make air tank be contained in washed between, between the cloth.Thus, prevent wrinklingly, also eliminate the washed sense of hardening.Temperature is high more, it is severe more that washed behind dry the end is positioned over the cylinder 13 washed wrinkling degree when inner, but because elapsed-time standards t is long more, temperature in the cylinder 13 reduces (near normal temperature) more, even, still do not damage preventing washed wrinkling effect so be classified to as described above increase under the situation of ta quiescent time.

On the other hand, because of following elapsed-time standards t, quiescent time, ta was classified to increase, thus rotational time tb and quiescent time ta ratio be classified to diminish.Therefore, power consumption reduces, effectively economize on electricity.In addition, as above-mentioned, front and back at ta quiescent time, drive solenoid 23a and torque motor 21a respectively, but, because ta quiescent time follows elapsed-time standards t, being classified to increases, so the driving number of times (driving time) in the unit interval of solenoid 23a and torque motor 21a also is classified to reduce.Because in most occasions, the life-span of such mechanism components is generally stipulated by action frequency, so if operating frequency is higher, then produce fault easily quickly, but, in the tumbling-box washing machine of present embodiment, solenoid 23a during by minimizing soft treatment stroke and the driving number of times (driving time) of torque motor 21a increase the life-span effectively.

In addition, in the superincumbent description, corresponding to the elapsed-time standards from finish time of dry trip, ta prolongs with quiescent time, still, in order to realize identical purpose, also can such as, by temperature sensor 33, monitor the variations in temperature in the cylinder 13, follow decrease of temperature, at leisure or be classified to prolong ta quiescent time.In addition, obviously, even do not corresponding to from the elapsed-time standards of the finish time of dry trip, and corresponding to cylinder as described above static/number of occurrence of rotation program, at leisure or be classified to prolong under the situation of ta quiescent time, still obtain identical effect.

1 of this tumbling-box washing machine is characterised in that in above-mentioned such laundry, dry operating, produces the control action of occasion that cover lock is decided the action failure of portion of mechanism 23.Be controlled to be example during below with the soft treatment stroke, this is described.Fig. 9 is the flow chart of main program that carry out repeatedly, top cover locking control action when the soft treatment stroke, Figure 11 is the flow chart of the secondary program of the motor action indication processing in the presentation graphs 9 for the flow chart of the secondary program of the key detection processing of uncapping in the presentation graphs 9, Figure 10.

At first, the key of uncapping among Figure 11 being detected processing is described.Detect in the processing at this key of uncapping, control part 30 is judged at operating portion 5a whether push the key 5b that uncaps, is realized connecting (step S60).In the occasion of key 5b of uncapping for connecting, set soft treatment and finish cue mark F2 (step S61), on the other hand,, do not carry out any processing, and turn back to main program (Fig. 9) in the occasion of key 5b access failure of uncapping.

Then, the indication of the motor action among Figure 10 processing is described.In the motor action indication is handled, control part 30 passes through timer, carry out timing (step S40) from the actuation time that the running of soft treatment stroke begins, judge the soft treatment duration of runs (being 120 minutes) that whether arrives regulation this actuation time here, thus, whether judgement the duration of runs that should carry out finishes (step S41).In the soft treatment unclosed occasion duration of runs, judge whether to set soft treatment and finish cue mark F2 (step S42).As above-mentioned, the action of setting flag F 2 refers to the occasion of the key 5b that uncaps being operated by the user.At this moment, and at step S41, it is identical to be judged to be the occasion that soft treatment finishes the duration of runs, carries out step S43.

The action of carrying out step S43 all refers to stop the rotation of cylinder 13, can open the occasion of the state of top cover 2.Therefore, at first set and carry out soft treatment end implementation flag F 3, then, judge whether rotary drum electrical motor 20 stops (step S44).In the occasion that rotary drum electrical motor 20 stops, the state of keeping intact, on the other hand, the occasion in that rotary drum electrical motor 20 does not stop to become termination with the motor action instruction, or being the occasion of ending, keeps abort state (step S45) continuously, turns back to main program.

At step S42, do not set the occasion of (that is, the key 5b that uncaps not being operated) of flag F 2, judge whether the motor action instruction continues (step S46).In the occasion that motor action instruction continues, upgrade the timing (step S47) of the drive actions time timer of rotary drum electrical motor 20, judge whether to arrive the Motor Drive time of regulation, thus, whether finish (step S48) during judging motor action.If do not finish during the motor action, then turn back to main program same as before.On the other hand, when finishing during the motor action, reset Motor Drive timer actuation time (step S49), the motor action instruction from continuing to become termination (step S50), is turned back to main program then.

At step S46, motor action is instructed unsustained occasion, promptly, be in the occasion of abort state, upgrade the timing that stops timer actuation time (step S51) of rotary drum electrical motor 20, judge whether to arrive the motor stop time of regulation, thus, judge whether the motor stopping period finishes (step S52).If the motor stopping period does not finish, then turn back to main program same as before.On the other hand, when the motor stopping period finishes, reset motor and stop timer actuation time (step S53), the motor action instruction from ending to become lasting (step S54), is turned back to main program then.

Below, the above-mentioned main program that the key detection is handled and the motor action indication is handled of uncapping that comprises among Fig. 9 is described.At first, control part 30 uncaps successively that key detect to be handled and the motor action indication handles that (step S20 S21), then, judges whether motor action is instructed is lasting (step S22).In the occasion of motor action instruction for continuing, if cylinder 13 is in the rotary course or cylinder 13 does not rotate, then necessary head roll motor 20, swing roller 13.At this moment, decide test section 23b, judge whether to be in cover lock and decide disarm state (step S23),,, so same as before, turn back to main program S20 because rotary drum electrical motor 20 has moved if it is fixed to carry out cover lock by cover lock.

On the other hand,, judge to be in the occasion that cover lock decide disarm state, owing in the process during the rotation of cylinder 13, must carry out cover lock and decide, so, carry out cover lock and move (step S24) surely by solenoid 23a is switched at step S23.Then, decide test section 23b, judge whether to be in cover lock and decide state (step S25),, then, make cylinder 13 rotations (step S35), turn back to step S20 by rotary drum electrical motor 20 is driven if cover lock is fixed by cover lock.On the other hand, although move surely if carry out cover lock, it is fixed not carry out cover lock yet, because having cover lock decides the possibility that the action of portion of mechanism 23 is broken down, so mode such as pipe of the lighting of the warning display by display part 5c, buzzer 5d, the circular cover lock is closed mistake (step S26) surely, stops action.Cover lock is closed mistake surely and is referred to have state at lid 2 non-lockings, the mistake that locks.

If at step S22, judge that the motor action instruction is not lasting, promptly, be in abort state, then follow, judge whether rotary drum electrical motor 20 stops (step S27), if rotary drum electrical motor 20 is not in halted state, then make rotary drum electrical motor 20 stop (step S28), turn back to step S20.

If at step S27, judge that rotary drum electrical motor 20 is in halted state, then follow, judge that soft treatment finishes to carry out flag F 3 and whether sets (step S29).Then,, decide test section 23b, judge whether to be in cover lock and decide state (step S30),, then follow, judge that cover lock removes prohibition flag F1 surely and whether set (step S31) if cover lock is fixed by cover lock in the occasion of not setting flag F 3.About this flag F 1, will be explained hereinafter.At step S30, remove the fixed occasion of cover lock, even and under the fixed situation of cover lock, still set the occasion of flag F 1, turn back to step S20 same as before.

In the occasion of not setting flag F 1, can open the mode of top cover 2 according to the user, 23a switches on to solenoid, carries out cover lock and removes action (step S32) surely, then, decides test section 23b by cover lock, judges whether cover lock removes (step S33) surely.,, then turn back to step S20 here if it is fixed to remove cover lock,, although remove action surely carrying out cover lock, do not remove the fixed occasion of cover lock yet, set cover lock and remove prohibition flag F1 (step S34) surely, turn back to step S20.In addition, flag F 1, F2, F3 all reset in the zero hour of soft treatment stroke.

As above-mentioned, according to step S32～S34,, do not remove the fixed occasion of cover lock yet although remove action surely carrying out cover lock, set cover lock and decide prohibition flag F1.But, even, still do not shut down in this occasion, and running continuously same as before.By temporary transient setting flag F 1, after, handle to arrive the occasion of step S31, turn back to step S20 from step S31.Thus, if temporarily set flag F 1, then do not carry out the cover lock of step S32 and remove action surely.

If as above-mentioned, even before finishing soft treatment actuation time, still the key 5b that uncaps is operated, if or the key 5b that uncaps is not operated, soft treatment finishes actuation time, then sets soft treatment and finishes to carry out flag F 3.Therefore, afterwards,, when arriving step S29, forward step S36 to from step S29 at first.By decide the detection signal of test section 23b from cover lock, judge at this moment and carve whether be in cover lock and decide state.At this moment, if be in the fixed state of cover lock of removing, then same as before, finish the soft treatment stroke.Because at this state, the rotation of cylinder 13 stops, and it is fixed with cover lock not decide portion of mechanism 23 by cover lock, and then the user can open top cover 2, takes out washed from mark 13.

On the other hand, if at step S36, judge that being in cover lock decides state, then solenoid 23a is switched on, then carry out the fixed releasing action (step S37) of cover lock, then, decide test section 23b by cover lock, judge whether that cover lock is in disarm state (step S38) surely.If it is fixed to remove cover lock, then the soft treatment stroke finishes same as before, still, if it is fixed to remove cover lock, then judges the possibility that the fixed releasing action that has cover lock is broken down.In this occasion, the modes such as the action that pipes of the lighting of the warning display by display part 5c, buzzer 5d, the circular cover lock is removed mistake (step S39) surely, stops action.Cover lock is removed mistake surely and is referred to have the state that locks at lid 2, the mistake of the implication that this locking can't be removed.

Yet, even in the running way of soft treatment stroke, cover lock is removed under the situation that can't realize surely, and the running of soft treatment stroke continues, last until the trip, in the moment that the trip finishes, attempt cover lock once more and remove surely,, remove impossible occasion surely at cover lock even in this case, the circular mistake stops action simultaneously.Thus, even in the running way, under the situation that top cover 2 can't be opened, finish required running itself, to the last, on the way, running is not ended.

On the other hand, in running way, cover lock decide disarm state relatively, and cover lock moves the occasion that can't carry out surely, if do not carrying out the fixed state of cover lock, cylinder 13 is rotated, and then has the problem of secure context.Therefore, in this occasion, as shown in step S24～S26, even under the situation in the running way, (that is,, do not pass through soft treatment actuation time even as above-mentioned, or under the situation of the key 5b that uncaps not being operated), still stop action apace, the circular mistake.Thus, can guarantee higher security.

In addition, the top example that is described as the soft treatment stroke still, in whole stroke of describing in Fig. 6, can be adopted and uses the same method.That is, in the fulfillment process of each stroke, fixed (promptly when should automatically removing cover lock, do not correspond to the operation of the key 5b that uncaps) time, though 23a switches on to solenoid, attempt cover lock and remove surely, still the occasion that can't remove, therefore, do not ending running, and whole strokes that end sets (such as, in the occasion of not carrying out dry process, before the dehydration stroke finishes) moment of running, can carry out the processing of above-mentioned steps S36～S39.

Equally such as because the abnormal ascending of environment temperature etc., the occasion that solenoid 23a temporarily is failure to actuate also is rare.Also have following situation, that is, in such occasion, even in the running way, under the situation that cover lock can't be removed surely, when running finished, cover lock was decided the functional rehabilitation of portion of mechanism 23, and cover lock is removed surely and can be realized.At this moment, finish owing to turn round, thus can be same as before, and what taking-up was washed from cylinder 13, drying is good is washed.Obviously, in the wrong occasion of final circular, owing to the possibility of the fault of deciding portion of mechanism 23 as cover lock is higher, so but places under repair such as user's contact service responsible person.

This tumbling-box washing machine also one be characterised in that the buzzer sound output when cover lock that the mode of switching on by the solenoid 23a that cover lock as described above decide portion of mechanism 23 is carried out is removed action surely controls.As described in resembling, carry out cover lock and remove action surely and be divided into the occasion that the user operates the key 5b that uncaps, under situation such as in the running way, when running finishes, and 2 kind situations of the occasion of automatically carrying out irrelevant with user's intention.

In the former occasion, obviously, suppose if the user extremely near this washing machine, removes cover lock and decides, then plan to open the situation of top cover 2 at once.Therefore, be convenient to remove action surely when carrying out, make the buzzer 5d action that pipes at cover lock, with this action notice to the user.On the other hand, automatically removing the fixed latter's of cover lock occasion, be not limited to the occasion of the extremely close washing machine of user, surely remove if also have corresponding to cover lock, buzzer 5d pipes, then the user is misinterpreted as the situation of certain fault, and the situation that buzzer 5d pipes with higher frequency is irksome after all.Therefore, carry out such control shown in Figure 12.

That is, control part 30 judges whether to carry out cover lock and removes action (step S10) surely, removes the occasion of action surely carrying out cover lock, the operation (step S11) of the key 5b that judges whether to uncap.In addition, in the occasion of the operation that the key 5b that uncaps is arranged, carry out the processing (step S12) of the action that pipes of buzzer 5d.On the other hand, even remove surely under the situation of action carrying out cover lock,, that is, remove the occasion of action surely at cover lock automatically, without step S12, end process in the occasion of the operation of the key 5b that do not uncap.Therefore, in this occasion, buzzer 5d does not pipe, and the user is not caused bored.

In addition, the foregoing description is an an example of the present invention, obviously, in the scope of essence of the present invention, suitably makes amendment, improves or add processing.Such as, in the above-described embodiments, the present invention is used for tumbling-box washing machine, still, if the present invention is the washing machine of lid (needn't be positioned at the top) lock function with the switching that realizes washed input port, certainly, can be used for the turbine type washing machine.
