Abstract
Energizing to a motor is stopped during the spin-drying operation in a rinsing process, so as to inertially rotating a spin-drying tub. When a fixed time elapses from the start of the inertial rotation, the rotation of the spin-drying tub is braked with a brake. The rotation of the spin-drying tub is lowered. When the number of the rotation reaches a setting value being the number of the rotation not to generate splashing even when water is supplied as the succeeding work, the spin-drying operation is stopped and a water supply process is started or operation is terminated. So that the inertial rotation time in a spin-drying operation is shortened and rapidly perform a shift to a succeeding work.
Description
Technical field
The present invention relates to wash in order, the washing machine of rinsing, each operation of dewatering.
Background technology
In automatic washing machine, be that the running of purpose is controlled at the spy and opens in the flat 9-253382 communique on the books to shorten rinsing time in the rinsing process.That is, after interrupting that the energising of motor stopped dehydration and driving, under situation, make the rotation of drench pit inertia, the rotating speed of drench pit become setting when following, change subsequent processings such as water supply over to without the brake braking.
Control the endurance life that to guarantee brake by above-mentioned running.And, carry out the water supply of subsequent processing later on owing to reduce the rotating speed of drench pit fully, so even the situation that has drench pit to be rotated, dabbling in the time of also can suppressing to supply water.
But in the above-mentioned running control, reaching until the rotating speed of drench pit in the inertia rotation after dehydration needs long time below the setting.Therefore, to being designed under the long situation of life-span of endurance life of brake,, exist the problem that unnecessarily prolongs the duration of runs although use brake also not have obstruction.
Summary of the invention
Therefore, the object of the present invention is to provide the washing machine that uses brake on one's own initiative, can shorten the duration of runs in a kind of inertia rotation when the dehydration running.In addition, purpose be to provide a kind of in the inertia rotation lid of drench pit be opened or can guarantee the washing machine of security when producing the such anomaly of brake troubles.
Washing machine of the present invention comprises: make the motor of drench pit rotation, to the arrestment mechanism that the rotation of drench pit is braked, detect the speed detector of the rotating speed of drench pit, motor and arrestment mechanism are carried out the control device of drive controlling when the dehydration running; This control device is when the dehydration running of rinsing process, stop after motor energising, in the inertia rotation, drive arrestment mechanism during through certain hour and the rotating speed of drench pit is reduced, when the rotating speed of this drench pit reaches setting value, stop the dehydration running, carry out the processing of subsequent processing.
Perhaps, the dehydration of dehydration procedure running the time stops after the motor energising, in the inertia rotation during through certain hour, drives arrestment mechanism and the rotating speed of drench pit is reduced, and stops the dehydration running when rotating speed of this drench pit reaches setting value, and termination turns round.
That is, in the inertia rotation of dehydration running, the rotation of drench pit is braked and is made the rotating speed reduction of drench pit.The rotating speed of drench pit becomes in the time of can allowing to carry out the rotating speed of next operation, although drench pit is being rotated, stops the dehydration running.Judge whether to become the rotating speed that can allow to carry out next operation according to the rotating speed of drench pit or by the time that brake begins to brake, the dehydration running is terminated when having reached setting value separately.After the dehydration running stops, carry out next operation immediately, can shorten the time.
If the running of the dehydration in the rinsing process, then next operation is the water supply operation.When supplying water,, also be low speed rotation, so can not cause and spatter the such phenomenon of water around because of generation dabbles even drench pit is being rotated.In addition, if the running of the dehydration in dehydration procedure, then next operation is the running termination, and what turn round and stop reports.Reporting by this, even open the lid of rotating drench pit, also is low speed rotation, so also be safe even hand is put into drench pit.
In addition, for when running dehydration drench pit lid do not open, also be provided with the locking mechanism that this lid is locked, the rotating speed of drench pit becomes setting value when following in the dehydration running, control device is just removed cover lock and is decided.Owing to after the rotating speed of drench pit reduces fully, can open and close lid, so can carry out next operation safely.
Also be provided with the cover open/close checking apparatus that the open and-shut mode of the lid that detects drench pit is used, control device detects the rotating speed of the drench pit when dehydration running middle cover is opened, and rotating speed carries out abnormality processing for lid opens wide permissible value when above.Even lid opens wide permissible value and is set at that hand is put into drench pit also is safe rotating speed, be made as greatlyyer than setting value, when the rotating speed of the drench pit when lid is opened opens wide permissible value less than lid, proceed the dehydration running.
That is, when the rotating speed of drench pit is fast, if lid is opened, abnormality processing such as then warn, it is dangerous reporting.In addition, for can allow that hand put into the rotating speed of drench pit the time, under the state of having opened lid, can proceed the dehydration running.Can take out washings in the meantime.
Also be provided with the display unit that shows that operation information is used, control device carries out different demonstrations according to the rotating speed of drench pit with respect to the size that lid opens wide permissible value.When the rotating speed of drench pit was higher than this permissible value, the demonstration of drawing attention to was not to open lid.Therefore, in the time of can preventing that the rotating speed of drench pit is fast because of not noting opening lid.When the rotating speed of drench pit is lower than this permissible value, even it is also no problem to open lid, so carry out to open wide the demonstration of lid or do not carry out any demonstration.
Control device is after driving arrestment mechanism, and the rotating speed of drench pit does not become setting value and carries out abnormality processing when following.The state of affairs that does not reduce owing to the unusual rotating speed that produces drench pit of arrestment mechanism.Therefore, even through certain hour, the rotating speed of drench pit does not reach setting value when following yet, is judged as unusually.Report unusually by warning demonstration or sound, remind the necessity that needs place under repair.
According to the present invention,, can stop the dehydration running when reducing the rotating speed of drench pit soon and reaching the rotating speed that does not hinder next operation by using brake on one's own initiative in the inertia rotation when dehydration is turned round.Therefore, even do not make drench pit stop fully also can beginning next operation, can realize the shortening of the duration of runs.
In addition, because of not noting, the lid of drench pit is opened or produces brake troubles and so on unusually the time in inertia rotation, according to the rotating speed of at this moment drench pit, can take the countermeasure warning or proceed to turn round and so on, so when guaranteeing security, the duration of runs can be shortened.

At this, a series of flow process as washing machine 100 runnings is set at: when power switch 118 is operated " connection " side, washing machine 100 startings, press initial setting operative norm process.At this moment, standard LED 128 bright lamps.
Drop into the clothes class in the drench pit 4 and when operating firing switch 117, microcomputer 41 is carried out washing procedure, rinsing process, final dewatering operation successively.Washing procedure is by opening water supply operation that feed water valve 18 supplies water, the agitating procedure of stirring vane 5 rotations being constituted.Rinsing process constitutes by driving drain motor 27 and opening the drainage procedure of draining valve 13, middle dehydration procedure, washing procedure and same water supply operation, agitating procedure.These operations as one group, are decided rinsing secondary or three inferior rinsing number of times according to selected process.
Middle dehydration procedure carries out such dehydration running: under the state that drives drain motor 27 by motor 7 being switched on or switched off control or carrying out Continuous Drive, become the dehydration driving condition of drench pit 4 rotations, through behind the dehydration driving time that is predetermined, make motor 7 stop to drive, just become the inertia rotary state, drain motor 27 is stopped, just making arrestment mechanism 24 actions, change the water supply operation then over to.Though the final dewatering operation is the same with middle dehydration procedure with the drainage procedure of rinsing process, stops sound after arrestment mechanism 24 action and report and wait the termination that turns round.
As mentioned above, the rotation of 41 pairs of drench pits 4 of microcomputer is braked in the inertia rotation, can shorten the time of dehydration running.In addition, according to the control of turning round of the rotating speed of drench pit 4, like this, can further shorten the duration of runs.The content of the running control according to Fig. 4 during to the middle dehydration procedure in the rinsing process describes.
At first, at S1-1, rinsing process turns round at the beginning, then at S1-2, drives drain motor 27, at S1-3, and CD-ROM drive motor 7 and make drench pit 4 rotations.Continue the dehydration driving condition until the counting of timer through 3 minutes, at S1-4, judge whether through 3 minutes.Be judged as when having passed through 3 minutes, make motor 7 stop to drive at S1-5.The dehydration driving condition finishes, and drench pit 4 just becomes the inertia rotation status.
Until continue the inertia rotation status through 30 seconds always,, passed through for 30 seconds after making motor 7 stop to drive,, stopped driving, just made arrestment mechanism 24 actions by making drain motor 27 then at S1-7 if be judged as at S1-6.Rotation to drench pit 4 is braked, and rotating speed just reduces.Then, judge according to whether being below the 10rpm from the input signal of rotation detecting 25, the rotating speed of drench pit 4 of 49 computings of operational part by CPU 42.Continue to make the inertia rotation status of braking when not reaching 10rpm.At S1-8, reach below the 10rpm if be judged as, then stop the dehydration running, at S1-9, the water supply operation after changing over to.At this, even the rotating speed 10rpm of drench pit 4 does not produce the rotating speed that dabbles and the setting value of setting as supplying water yet.Therefore, cover 16, when opening, also can not spatter Shang Shui on one's body, the ground of the user's dwelling house of perhaps can not getting wet because of dabbling the user even when this rotating speed is following, open.
As mentioned above, the dehydration running is terminated when setting value because the rotating speed of drench pit 4 reaches, and carries out subsequent processing immediately, so can shorten the time of dehydration running.In addition, owing to begin through braking behind the certain hour (30 second),, can be soon the rotating speed of drench pit 4 be dropped to setting value, can shorten the duration of runs therefrom so compare with continuing the occasion that inertia rotates from inertia rotation.In addition,,, can reduce the load that arrestment mechanism 24 bears, prolong the fatigue life of arrestment mechanism 24 so the rotating speed of drench pit 4 drops to a certain degree because of until making arrestment mechanism 24 actions will pass through certain hour.
When the final dewatering operation also with the above-mentioned the same control of turning round.That is, as shown in Figure 5, at S2-1, the final dewatering operation turns round at the beginning, just drives drain motor 27 at S2-2, makes drench pit 4 rotations at S2-3 CD-ROM drive motor 7.Continue the dehydration driving condition until the counting of timer through 6 minutes, be judged as when having passed through 6 minutes at S2-4, make motor 7 stop to drive at S2-5.Stop the dehydration driving condition and become the inertia rotation status.
Continue the inertia rotation status until after the driving that stops motor 7 through 30 seconds till, at S2-6, passed through for 30 seconds if be judged as, then at S2-7, drain motor 27 stopped and making arrestment mechanism 24 actions.Then, at S2-8, when the rotating speed of judging drench pit 4 is 10rpm when following, at S2-9, termination turns round.That is, report the termination sound and make the user know that running stops.
After reporting the termination sound, want to take out immediately under the situation of clothes class, because the rotary speed of drench pit 4 is fallen very lowly, so, also can take out the clothes class safely even under the state that drench pit 4 is rotated, hand is stretched in the groove the user.This dehydration procedure also can make the termination time of dehydration running shift to an earlier date, and can shorten the time.
Yet in the dehydration procedure implementation, the cover lock that cover lock is decided mechanism will cover 16 lockings with solenoid 22 actions surely, so that the lid 16 of drench pit 4 is not opened.When dehydration running stopped, microcomputer 41 was removed the control of covering 16 locking.
That is, as shown in Figure 6, in rinsing process, after middle dehydration procedure begins,, drive solenoid 22 at S3-3.Covering 16 for the sake of security can not be locked with opening and closing.Later dehydration running is carried out with order shown in Figure 4 the samely.
When the speed drop of drench pit 4 is low to moderate setting value promptly less than 10rpm, drive solenoid 22, the releasing that locks at S3-10.Enter later water supply operation at S3-11.Like this, remove and to cover after 16 the locking user and will take out the clothes class immediately and maybe will add the clothes time-like, even drench pit 4 also is low speed rotation under the state that is rotated, so hand can be stretched in the drench pit.Therefore, can be under the state of safety open-close lid, can carry out the preparation of subsequent processing as quick as thought, can shorten the total time of laundry.When in addition, the fixed open and close controlling of above-mentioned cover lock also turns round applicable to the final dewatering operation.
In addition, microcomputer 41 detects in dehydration running and cover 16 when being opened, the rotating speed of detection drench pit 4.This rotating speed carries out abnormality processing for lid opens wide permissible value when above.Rotating speed is lower than when lid opens wide permissible value and does not carry out abnormality processing, proceeds running as before.
That is, as shown in Figure 7, in rinsing process, begin to carry out the centre dehydration procedure.The dehydration running is carried out with order shown in Figure 4 the samely.At S4-8, checking the rotating speed of drench pit 4 whether to reach lid at any time, to open wide permissible value be 30rpm.Be 30rpm when above,, detect the user by lid switch 26 and opened lid at 16 o'clock, carry out abnormality processing (fault processing) at S4-10 at S4-9.For example report warning tones or show error code, this error code is represented unusual kind.
If the rotating speed of drench pit 4 is below the 30rpm, do not carry out fault processing under 16 situations about opening even then will cover the user yet.Drench pit 4 continues rotation under lid 16 states of opening.Then, when the rotating speed of drench pit 4 is below the 10rpm,, change later water supply operation at S4-12.When the control when in addition, above-mentioned lid 16 opens wide also is applicable to the running of final dewatering operation.
Even lid opens and closes permissible value 30rpm and as the user hand is stretched in the drench pit 4 also the rotating speed of the safety of hurtless degree to set.Open and close permissible value when high under lid 16 situations about being opened at this lid of rotating ratio, dangerous because of reporting as described above to the user, so can restrain hand is stretched into the interior behavior of drench pit 4.In addition, under lid 16 situations about being opened, not carrying out fault processing when rotating ratio lid switching permissible value is low, like this, is safe state although can solve, but this unfavorable condition that gives a warning.
At this moment, because microcomputer 41 detects the rotating speed of drench pit 4, and check whether reached lid switching permissible value, so carry out demonstration according to this result.As shown in Figure 8, when dehydration running beginning, make rotation note LED 132 bright lamps at S5-3.When the rotating speed of drench pit 4 reaches lid switching permissible value 30rpm, make rotation notice that LED 132 turns off the light at S5-10.Action is in addition carried out with order shown in Figure 4 the samely.Action when lid 16 is opened is carried out with order shown in Figure 7 the samely.
The user will open and cover at 16 o'clock in the dehydration running, can notice whether the bright lamp/rotation of confirming drench pit 4 of turning off the light of LED 132 is dangerous state by rotation.Therefore, though can to prevent be that dangerous rotating speed and opening cover 16 handles and stretches into the interior behavior of drench pit 4 in possible trouble.When in addition, this control is also turned round applicable to the final dewatering operation.
In the inertia rotation,, the rotating speed of drench pit 4 is reduced by arrestment mechanism 24 actions are braked again.But the unusual rotating speed that waits some reason to make drench pit 4 because of arrestment mechanism 24 is not normally to reduce sometimes.Therefore, microcomputer 41 makes the rotating speed of arrestment mechanism 24 action back check drench pits 4, is not when normally reducing at rotating speed, and it is unusual to be judged as brake, carries out abnormality processing.
As shown in Figure 9, the dehydration of rinsing process is turned round at the beginning, and then the same with the order shown in Figure 4 drain motor 27 that makes stops to drive, and the rotation of drench pit 4 is braked.Thereafter, whether the rotating speed at S6-8 check drench pit 4 reaches setting value.If being judged as the rotating speed of tank 4 is below the 10rpm, then change later water supply operation at S6-11.
Usually, arrestment mechanism 24, begins to become below the 10rpm through the rotating speed of drench pit 4 about 5～10 seconds from the brake action though also depend on the amount of the clothes class in the drench pit 4 for just often.Therefore, even also do not become under the following situation of 10rpm through certain hour after drain motor 27 is stopped, microcomputer 41 is judged as brake to be had unusually.This certain hour is set at than just often 5～10 seconds longer 30 seconds.When having passed through 30 seconds,, make and check that LED 133 bright lamps are as abnormality processing at S6-10.When in addition, this control is also turned round applicable to the final dewatering operation.
Unusual as brake, bad brake this class fault etc. of being failure to actuate that makes of action when being commonly considered as stopping because of brake wear or drain motor 27.When dewatering running under such state, the possibility that produces accident as described above improves, so must hasten to check and repair.By checking LED 133 bright lamps, the necessity that can notify the user to know this repairing can prevent trouble before it happens accident.
Certainly, the present invention is not limited to above-mentioned form of implementation, can carry out a lot of corrections and change to above-mentioned form of implementation within the scope of the invention.In above-mentioned form of implementation, the time that stops the dehydration running is the rotating speed of drench pit when reaching setting value, but because of capacity, the material difference of washings, the reduction situation difference of the rotating speed of drench pit.Therefore, capacity, the material according to the washings that is detected in advance calculates the termination time.When the braking of brake begins to pass through the termination time that is calculated, the water supply operation or the running termination of carrying out next operation.Like this, the dehydration running can be stopped,, the dehydration running can be stopped soon particularly in the less occasion of washings according to the washings of reality.
Though this invention at length is illustrated, represents, this is just for illustration, and not as limiting, the spirit and scope that should understand invention only limit according to claims of enclosing.
