Abstract
While a drain pump is driven after wash water in an outer basket is entirely drained, no wash water flows into the drain pump and therefore the wash water collects in a drain pipe extending from the drain pump. Therefore, when the drain pump is turned off after the start of a dewatering stroke, the wash water collecting in the drain pipe flows back into the drain pump, so that even if air is trapped in the drain pump, the air sucked in the drain pump is returned into the outer basket by the washing water flowing back from the drain pipe. As a result, the drain pump is released from its air trapping condition and restored to its normal condition. Therefore, it can smoothly drain wash water squeezed out of the wash by dewatering by releasing a drain pump from an air trapping condition.
Description
The present invention relates to a kind of can by draining pump with the slurry in the washing machine hoist the discharging washing machine.
In the past, for example on Australia and South America and other places, employed washing machine can be discharged into slurry stream platform geometric ratio washing machine also high place, position was set.In this washing machine, be furnished with and be used for by draining pump the washings in the washtub having been drawn holding the draining pump that the washings of staying washtub are extracted out, be discharged into and flow in the platform etc.
In addition, in this washing machine, is furnished with the level sensor that is used to check washtub washed water water level.Level sensor for example links to each other with the air valve that is formed at washtub bottom by air blanketing, detects water level in the washing machine according to the air pressure variations in the air blanketing.Therefore, the detectable water level of this level sensor has certain limit, and the following water level of certain lower limit can not be detected.Therefore, for traditional washing machine, be by from detecting decline of water table in the washtub by level sensor to above-mentioned lower limit water level, judge that through the moment after the scheduled time washings in the washtub all are discharged from.
Yet,, under the situation of after racking up washings, washings being dewatered, can not well in washtub, discharge from the washings that washings is extruded for above-mentioned washing machine.Specifically, the washings in the above-mentioned scheduled time in the washtub are all discharged, and when continuing to drive draining pump under not having the state of washings, air flows in the draining pump, and draining pump produces and mixes air (ェ ァ nibbles body), can not give full play to its function.When beginning to dewater with this state owing to mix air and make the drainability of draining pump low, so that the discharge situation of the washings of extruding from washings is poor, the residual water that has under getting rid of in washtub.
Particularly, in the middle dehydration of between washing process and flushing process, carrying out, under the water of taking off from washings can not the situation of fine discharge, the interior residual water that takes off that contains washing agent that has of washtub, rotary dehydration barrel remains in the interior water that takes off of washtub and can produce foam in this state.And, the revolution of dehydration barrel can not be reached more than the required revolution, thereby can't carry out good dehydration washings because the foam that produces becomes the rotation that hinders dehydration barrel.In addition, because the foam that produces hinders the rotation of dehydration barrel, cause the problems such as power consumption increase of the motor that is used for rotary dehydration barrel.

Fig. 2 is the block diagram of the electric composition of this automatic washing machine of expression.This automatic washing machine is furnished with the microcomputer 30 that is used to control each component movement of washing machine.The ROM31 of storage washing machine each operation of components program is housed in the microcomputer 30, when execution is stored in program among the ROM31, has RAM32 as work functions, and the timer 33 that the operating time is measured.
In addition, microcomputer 30 is connected with water-supply valve 8, draining pump 10 and motor 20.Microcomputer 30, according to signal by level sensor 15 inputs, according to the program that is stored among the ROM31, the switch of control water-supply valve 8, and the ON/OFF of control draining valve 10 and motor 20.
Fig. 3 is the open/close state time diagram that is illustrated in draining pump 10 and motor 20 in drainage procedure and the dehydration.Fig. 4 is illustrated in the drainage procedure in the dehydration, near the diagram of the mobile status of the washings the draining pump 10.
The user presses the initiating key that for example is configured in above the casing 1 after inserting washings in the interior bucket 4, and when beginning was moved in washing, the washings of appropriate amount hold to be stayed in the outer bucket 3, carries out initial washing process.Then, when this washing process finishes, begin to be used to discharge the draining pump 10 of the washings in the outer bucket 3, beginning drainage procedure (t1, Fig. 4 (a)).
In carrying out drainage procedure, microcomputer 30 is the output signal of reference level sensor 15 always, and whether the water level in the outer bucket 3 of monitoring reaches level sensor 15 can detected lower limit water level C.When the water level of bucket in 3 reaches above-mentioned lower limit water level C outside detecting (t2), time T is appended in the draining that setting is stored among the ROM31 in advance in timer 33, begins to carry out the metering that time T is appended in this draining.
Time T is appended in draining, is set to hold the washings of staying in the outer bucket 3 that reach lower limit water level C and discharged the necessary sufficient times fully in outer bucket 3 by draining pump 10.Therefore, reach moment after above-mentioned lower limit water level appends time T through draining, hold the washings that stay in outer barrel 3 by emptying (Fig. 4 (b)) at the water level in outer bucket 3.Thereby, reach timing time in response to timer 33, start motor 20, begin to be used to remove the dehydration (t3) of the washings that washings is housed.
In dehydration, stop motion motor 20 (intermittently dewaters) after the rotation of bucket 4 in the raising gradually, by bucket 4 in the 20 high speed rotations of Continuous Drive motor, carries out washings and dewaters.Specifically, from the stipulated time (t3-t6) that dehydration begins, be the on/off operation of the cycle carrying out motor 20 repeatedly for example with 6 seconds/4 seconds.Whereby, progressively improve the rotating speed of interior bucket 4, the washings in the interior bucket 4 can not depart from interior bucket 4, are pressed at large on the inner peripheral surface of interior bucket 4.Then, begun by dehydration, after the time (t6), with preset time Continuous Drive motor 20, internally the washings in the bucket 4 dewaters through afore mentioned rules.
As what in the part that prior art is described, illustrate,, when not having washings in the bucket 3 inside and outside time T is appended in above-mentioned draining,, draining pump 10 suction air mix air owing to producing for the washing machine that carries out draining with 10 pairs of washings of draining valve.And, under the situation of dewatering, can not discharge well, outside the bucket 3 interior residual water that take off that have from the washings that washings is extruded with this state.
Therefore, in the present embodiment, by after beginning in dehydration in accordance with regulations timing within a certain period of time (for example 2～4 seconds) turn off draining pump, can remove the air that flows in the draining pump 10, the recovering state that makes draining pump 10 is to normal condition.Specifically, draining pump 10 finishes from drainage procedure.Dehydration has begun, and through behind the certain hour, is switched off (t4).Then, draining pump 10 for example after the closed condition in 4 seconds, switches to out (t5) once more through the predetermined shut-in time.
Shown in the hatching among Fig. 4 (b), holding after the washings of bucket in 4 discharge fully outside staying, under the state that drives draining pump 10 further drainings, because washings can not flow into draining pump 10, so leave washings extending in the drainpipe 13 that flows platform 12, to hold from draining pump 10.Therefore, when after dehydration begins, closing draining pump 10, hold the washings of staying in this drainpipe 13 and flow backwards, flow into draining pump 10.Therefore,, draining pump 10 mixes air, bucket 3 interior (with reference to Fig. 4 (c)) outside inhaled air also can be returned to by the washings of returning from drainpipe 13 refluences in the draining pump 10 even producing.Thereby, can eliminate the air that mixes of draining pump 10, make draining pump 10 return to normal condition.
Therefore because the washings extruded from washings thereafter can well be discharged by draining pump 10, so the water of taking off from washings can not hold stay outside in barrels 3.Because it is different with traditional automatic washing machine, so in dehydration, can not produce foam, and, owing to can not hinder the rotation of interior bucket 4 because of foam, in bucket 4 revolution can reach required revolution, can not produce the problem that the power consumption of the motor 20 of bucket 4 in being used to rotate increases.
In addition, be used to eliminate draining pump 10 mix air condition close the timing of draining pump 10 time, when for example reaching 200～300rpm with the revolution of motor 20 for well.At this timing point, by closing draining pump 10, produce before the bubbles in the bucket 3 outside, guarantee to eliminate the air condition that mixes of draining pump 10.
In addition, be used to eliminate the timing of closing draining pump 10 that draining pump 10 mixes air condition, needn't one fix on after dehydration begins, if start the timing of draining pump 10 once more is after dehydration begins (motor 20 starts the back), then bucket 3 interior decline of water tables arrive after the level sensor 15 detectable lower limit water level C outside, also can close draining pump 10 before dehydration begins.
And then in this embodiment, draining pump 10 is for the number of times of closed condition is exemplified as certain situation in the dehydration, but draining pump 10 for the number of times of closed condition also can be repeatedly.For example, torque ratio corresponding to motor 20 is less, and the drainability of draining pump 10 is than condition with higher, especially when motor 20 starts, because the washing water yield of extruding from washings is not very few, in case draining pump 10 had generation once more to mix the danger of air after elimination mixed air condition.Therefore, in this case, it is better to make draining pump be in closed condition more than 10 time in the dehydration, like this, can prevent to mix air condition Continuous Drive draining pump 10.
Fig. 5 is the diagram that is used to illustrate second embodiment of the invention.In Fig. 5, partly adopt identical label with each one shown in Figure 1 is corresponding, and omitted detailed description thereof.
The feature of second embodiment, with above-mentioned first embodiment in dehydration, eliminate like that draining pump 10 mix air condition different be, outside the decline of water tables of bucket in 3 to than the bottom surface of interior bucket 4 also by under after, before washings outside remaining in the bucket 3 are discharged fully, the beginning dehydration the anti-possible trouble that terminates in of air condition occurs mixing with draining pump 10.
Specific description is as follows, for example after washing process finishes, when starting draining pump 10, holds the washings of staying in the outer bucket 3 and begins to discharge, and the water level in the outer bucket 3 reduces.Then, the decline of water table in the outer bucket 3 is during to predetermined beginning water level A (with reference to Fig. 5 (a)), the metering in beginning elapsed time after this, and the water levels in the outer bucket 3 of metering arrive the time of the stopping water level B (with reference to Fig. 5 (b)) that is scheduled to.
Therefore, the water level that measures in the outer bucket 3 drops to the required time of stopping water level B from beginning water level A, according to the time of measuring, set out from the decline of water table in the outer bucket 3 to below the detectable lower limit water level of level sensor 15 (with reference to Fig. 1) C to definite time delay that dehydration begins.
The discharge situation of washings changes along with the situation of the washings in the bucket 4 in being contained in.That is, under the situation of the washings that good water absorption is housed, or under the washings that the holds situation how,, need the long period to discharge washings owing to be soaked with a large amount of washings in the washings.On the other hand, under the situation of the washings water imbibition difference of in interior bucket 4, holding, discharge the required time weak point of washings.
Therefore, drop to the required time of stopping water level B from beginning water level A, can judge the situation of the washings in the bucket 4 in being contained in by the water level of measuring in the outer bucket 3.Then, according to the judgement of the washings situation in the internal bucket 4, the decline of water tables in the bucket 3 as described time delay, are come setting-up time holding the mode that begins dehydration before the washings that stay in outer bucket 3 are discharged fully after also lower than interior bucket 4 bottom surfaces in addition.
When above-mentioned time delay of setting like this, the water levels in outer bucket 3 reach lower limit water level C (with reference to Fig. 5 (c)), through the moment after the time delay of setting, start in being used to rotate barrels 4 motor 20 (with reference to Fig. 1).At this moment, shown in the hatching among Fig. 5 (d), a spot of washings are arranged, not mix air state and begin dehydration so can not produce with draining pump 10 because bucket is residual in 3 outside.Therefore, the washings of extruding from washings in the dehydration can well be discharged by draining pump 10, thereby can obtain the same effect with above-mentioned first embodiment.
More than, two embodiment of the present invention are illustrated, but the present invention is not limited to above-mentioned two embodiment.For example, in the various embodiments described above, control when proposing and having illustrated the drainage procedure that between washing process and flushing process, carries out and middle dehydration, but the present invention also goes for the drainage procedure that carries out and the control of final dewatering process behind flushing process.
In addition, if be furnished with the automatic washing machine that draining pump, this draining pump are discharged to the washings in the outer bucket eminence, the present invention all can be suitable for widely, for example, be provided with the full-automatic bucket that can wash and dewater, at side configuration bobbing machine, full-automatic bucket in the adjacent double barrels type washing machine that is provided with the auxiliary washtub that can wash and wash also is applicable to the present invention.
In addition, in the scope of the technical scheme that is recorded in the claim scope, can carry out the variation in the various designs.
