Description
Technical field
The present invention relates to a kind of washing machine that can control the action of washing, rinsing operation according to the dirty situation of cleaning solution.
Background technology
In the washing machine of prior art, judge that by the muddy degree that detects cleaning solution whether washing is finished is known technology, an example wherein can be opened clear 57-66793 (calling list of references 1 in the following text) with reference to the open communique spy of Japan Patent.
In addition, the open communique spy of Japan Patent open also disclose among the clear 61-159998 (calling list of references 2 in the following text) a kind of after detecting turbidity, under the situation of restarting then to turn round at the washing machine pausing operation, the technology that can readjust the sensitivity of turbidity detector.
Moreover, also have in the prior art a kind ofly can prevent to the variation that is the washings turbidity that dirt caused that from clothing, separates, or the turbidity that suspended material caused such as line bits changes and makes erroneous judgement, thereby avoid the technology of turbidity flase drop, an example wherein can be opened flat 06-000279 (calling list of references 3 in the following text) with reference to the open communique spy of Japan Patent.
Fig. 5 is illustrated in the schematic diagram that the output voltage of turbidity sensor in the washing process of the washing machine that list of references 1 disclosed changes along with the variation of turbidity.In Fig. 5, curve c represents is the variation of the output voltage of turbidity sensor when detecting the water of low turbidity, and the variation of curve d represents when being water when the high turbidity of the detection output voltage of turbidity sensor.Under the high situation of turbidity, carry out the voltage change of characteristic conversion and acquisition curve e at the D point.In either case, all as shown in Figure 5, along with the carrying out of washing running, dirt splits away off from clothing, and the turbidity of cleaning solution increases, and output voltage also constantly increases.The technology that list of references 1 disclosed is exactly a kind of by detecting that output voltage increases and the state after the turbidity vary stable is judged the technology that washing is finished.
Fig. 6 is the flow chart of the control action of the washing machine that disclosed of expression list of references 2.As shown in Figure 6, the washing machine that list of references 2 is disclosed in the washing course of action, makes after washing machine suspends by time-out portion input stop signal, when turning round again, the turbidity detector will be tackled sensitivity mutually according to turbidity at that time again at this time point and be adjusted automatically again.In this way, even such as append thrown in new dirty washings after more again under the situation of running, the turbidity that also still can correctly detect the back changes.
Fig. 7 is the schematic diagram that the turbidity of the washing machine that disclosed of expression list of references 3 changes.In Fig. 7, just often turbidity changes shown in solid line, and under the situation that the wired bits in turbidity sensor test section enter, and is shown in dotted line, and the output of turbidity sensor is at the T2 time point P point that declined to a great extent.At this moment, the operation values Δ V T ' ratio operation values Δ V T just often that changes with respect to the turbidity of the washings of T1 time point greatly.Therefore, shown in concluding time point T4, this time point (concluding time point T3) of being set for mistakenly the running time of washing process than just often is longer.The washing machine that list of references 3 is disclosed just carried out turbidity and detects, if rate of change below setting, will finish washing process before the stipulated time of this setting concluding time point T4.
That is to say that the muddy degree of the reality of washings can not wait the arrival of the concluding time point T4 that is by mistake established again as shown in the output just often, and can finish the judgement of degree early.Under the situation that the wired bits in turbidity sensor test section enter, meeting just begins to finish the judgement of degree before in the stipulated time (such as 2 minutes) of this concluding time point T4, so can know just often concluding time point by the judgement inspection that finishes degree, and the shortest before the stipulated time of concluding time point T4 (such as the T3 time point) just finish washing process.So the situation that causes turbidity to descend also still can avoid washing excessively even go out that foreign matter such as accidental wired bits of phenomenon turbidity detection portion attaches.
Yet, in this technology in the past, have following these problems.When detecting turbidity, be to be prerequisite when washing has just begun, under the washing and dewatering bucket is intake the state of specified water level, to detect.That is to say, be the state after detergent dissolution is in washings, and, detection be the turbidity that contains under the A-stage of the dirt of stripping in washings.So the time of detecting the required cost of turbidity is long, and the accuracy of detection of turbidity also has problems.
In addition, rely on technology in the past, if will be to detecting the washing agent kind, and washing process and rinse cycle aspect after correspondingly setting according to the kind of washing agent control, and is to be difficult to realize by carrying out the mode that turbidity detects behind this specified water level of intaking in the past again.

In the circuit block diagram of Fig. 2, control device 80 has a control part 87, control part 87 by load drive division 86 control motor (drive division) 48, clutch 49, the oven dry that constitutes hot blast air supplying part 61 is with fan 55 and heater element 56, draining valve 74, the cooling action with parts such as pressure fan (cooling end) 79, water intaking valve 70 and pulsating pumps 91, and each process of washing, rinsing, dehydration, oven dry and degerming, deodorisation process are controlled.
Simultaneously, light permeability that control part 87 obtains according to the cleaning solution conductance of obtaining from conductance test section 78, from turbidity detection portion 92 and its rate of change, having or not with the kind of washing agent and the degree of fouling of clothing etc. of washings detected, and each process is controlled.
The structure of control part 87 has been guaranteed in drying course, when reaching first set point of temperature (for example: 110 ℃) by temperature detecting part 63 detected temperature, will cut off heater element 56, and the temperature that records when temperature detecting part 62 at this moment (for example: in the time of 2 degree) has descended second set point of temperature, will allow heater element 56 move, to regulate the temperature of circulated air.
Subsequent, we to said structure in the present embodiment, the content according to the degree of fouling of cleaning solution carries out corresponding action control describes by the elemental motion in washing, rinsing, dehydration.
Fig. 3 represents be in the embodiment of the invention 1 washing machine from washing to the program list till dewatering.And Fig. 4 represents be this washing machine from washing the flow chart of the control till the rinsing.
In the program list of Fig. 3, elemental motion is made up of the process of washing process, rinsing (1), the process of rinsing (2) and the process of dehydration.In the flow chart of Fig. 4, in washing process, the user opens enclosing cover 69 earlier, opens middle cover 66 again, drops into clothing in interior bucket 44, has set running program entry into service (S101) afterwards by input configuration part 83.So, washing machine will detect (S102) by the cloth amount that 93 pairs of cloth amount test sections have dropped into, and determine the consumption of corresponding water level, washing agent according to the cloth amount by control part 87, and the program after the decision for the time being, and show (S103) accordingly at display part 84.
Simultaneously, 70 actions of the water intaking valve of low discharge, beginning are to the water inlet of washing hose 72 sides (water inlet b), in official hour, with the water yield that roughly is full of drainpipe 75 from cleaning hard tube 77 in drainpipe 75, intake (S104).Then, utilize the turbidity D0 of the running water that turbidity detection portion 92 detects into, and turbidity D0 is judged (S105) afterwards, these data are input to control part 87.
Herein, the water inlet of the low discharge side of water intaking valve 70 is designed to only the reasons are as follows to drainpipe 75 water inlets (water inlet b): if allow the water intaking valve 70 of big flow move, inwardly provide running water (water inlet words a) in the bucket 44 via water supply hose 73, owing to accumulate at drainpipe 75 after running water will penetrate dirty linen, therefore be subjected to the influence of the dirt in the clothing, just might detect the turbidity of running water exactly.But,, just can not be subjected to the influence that material such as clothing dirt sneaks into and detected accurately turbidity by intake on a small quantity from cleaning hard tube 77 sides (water inlet b).
In addition, water level settings is to raise gradually successively from the 1st grade to the 9th grade.Water level till the 3rd grade all is the water level that is lower than impeller 46 peripheral part upper surfaces.And all be to stir the water level of c running according to common wash agitation b, rinsing that the cloth amount correspondingly will be described later from the 4th grade to the 9th grade water level.The 9th grade of water level is the highest water level.Here, what Fig. 3, Fig. 4 represented is that the cloth amount is many, and testing result requires to be set at the example under the situation of the 9th grade of high water level.
Then, the user is according to the prompting of this washing agent consumption, and corresponding input washing agent (S106) is though perhaps not expression in the drawings drops into washing agent automatically by washing machine.Then, by the process of water inlet b, just water intaking valve 40 actions of low discharge via washing hose 92, are cleaned hard tube 77, by drainpipe 75, tube connector 53, from descending the 1st grade of water level (S107) of intaking in the side direction bucket.The peripheral part upper surface of the 1st grade of water table ratio impeller 46 also will hang down about 100mm, is the water level that allows conductance test section 78 soak in water, and washing machine detects water level (S108) afterwards by conductance test section 78, and water inlet stops (S109).
In addition, the water level detecting portion 90 that illustrated of front has adopted this low-cost mode of generally using of hydraulic pressure that detects behind air trap 95 pressurizeds that are arranged on the outer bucket 43 on washing machine.Yet, accurately detect the minimum one grade water level that also hangs down about 100mm than impeller 46 peripheral part upper surfaces as if coming in this way, because hydraulic pressure is very little, its detection is quite difficult.But, if utilize conductance test section 78 to detect, just can correctly detect:, arrived the water level of minimum a grade (the 1st grade) exactly when water touches the time point of the pair of electrodes 94 of conductance test section 78.
Then, washing machine is under draining valve 74 closing state, the clutch 49 of transmission mechanism portion is switched to the dehydration side, the power of motor 48 is delivered to interior bucket 44 via dehydrating shaft it is rotated, and allow interior bucket 44 with about 100 rev/mins slowly running (bucket spinning movement) (S110) with impeller 46.In this way, the cleaning solution in the bucket rotates between interior bucket 44 and outer bucket 43 under action of centrifugal force lentamente, and cleaning solution just can not attach on the dirt of clothing, and washing agent can be dissolved fully.Then, stop (S110x) afterwards, carry out turbidity and detect, and turbidity D1 is judged (S111) in the bucket rotation.That is to say, utilize turbidity detection portion 92 to detect the initial value of the caused turbidity of washing agent in the cleaning solution, and these data are input to control part 87.Then, by turbidity D1 and turbidity D0 are compared (D1-D0), be relevant washing agent kinds of information such as powder detergent or liquid detergent by control part 87 with what judge (S112) employing.
Then, washing machine the 2nd grade of water level of intaking on one side, on one side under draining valve 74 closing state, the clutch 49 of transmission mechanism portion is switched to the dehydration side, bucket 44 rotated it in the power of motor 48 was delivered to via dehydrating shaft, and in allowing bucket 44 with impeller 46 with the low speed lower than above-mentioned speed---about 35 rev/mins speed is rotated (water inlet ﹠amp; The bucket rotation) (S111x).Then, stop (S111y) afterwards in the bucket rotation, the 3rd grade of water level (S113) of intaking utilizes the clutch 49 of transmission mechanism portion that the power of motor 48 is delivered to impeller 46 via wash shaft again, carries out impeller stirring a (S113x) running that impeller rotates.And then the 5th grade of water level (S114) of intaking, and carry out impeller and stir a (S115) running.The detection of a plurality of water levels more than the 2nd grade when intaking for these all is that the water level detecting portion 90 by pressure type carries out.
By these actions, washing machine is at the water level that is lower than specified water level (being the 9th grade of water level of setting according to cloth amount testing result) herein---and be that water level than low 4 grades of peak level (the 9th grade of water level) carries out so-called washing agent high concentration and stirs running herein, can either make and bubble fully, can allow dirt stripping in the clothing again in cleaning solution.Subsequently, action stops (S115x) afterwards, utilizes turbidity detection portion 92 to detect the muddy degree of cleaning solution, and once more detected turbidity D2 is judged (S116).That is to say, when utilizing turbidity detection portion 92 to detect the turbidity D2 of cleaning solution, is the dirt on the relevant clothing that few data that still are are input to control part 87 more, after by control part 87 decision content of the decision content of itself and turbidity D0 and turbidity D1 being contrasted, carry out the computing (S117) of determination procedure described later again.
Washing machine is according to this operation result, and can decision be shortened the time of wash agitation b (S119) and shorten the time that c (S123) is stirred in the rinsing in the rinse cycle, and the program after the decision.That is to say, employed when being liquid detergent when judging, because the foam of liquid detergent rinses easily, so just can perhaps reduce the number of times of rinsing according to detected cloth amount and the rinsing of determining is for the time being stirred the rinsing time of c and shortened.Simultaneously, when judging that dirt on the clothing also lacks than specified degree, just can be according to detected cloth amount and the time of the wash agitation b in the washing process of determining for the time being shortens.
After program is decided, allow the water intaking valve 70 of big flow move, begin inwardly to intake in the bucket 44, till reaching specified water level, under the situation of Fig. 3, till the peak level of intaking (the 9th grade of water level) (S118) by water supply hose 73.Behind the water inlet end, washing machine begins to carry out wash agitation b (S119) running according to the time of deciding previously, and under the rotation of impeller 46, clothing colludes the stirring protuberance 51 that tangles on the impeller 46, is taken to central part.And the clothing that is positioned at the center lower floor position of bucket 44 is originally brought into the position, upper strata that the clothing that comes is elected bucket 44.Washing machine comes to this by the clothing in the bucket 44 in stirring, utilize between the clothing or wash with mechanical force, flow force that the inwall of interior bucket 44 produces with contacting of impeller 46, stripping is in washings gradually for dirt contained in the clothing, and the muddy degree of washings changes thereupon.
After the wash agitation b running that begins washing process under the specified water level (the 6th～9 grade of water level) of regulation, washing machine also will utilize the muddy degree of 92 pairs of cleaning solutions of turbidity detection portion to detect, and turbidity D3 is judged (S120).That is to say, whether washing machine can rationally verify (S121) by the control that control part 87 carries out its detection of being judged according to turbidity D2, and according to this result, to after wash agitation b (S122) in wash time, rinsing (1) stir rinsing number of times and the time that c (S123) and rinsing (2) stir among the c (S124) and replenish correction.
The judgement of the turbidity D0 of above-mentioned each step～D3 and the relation that detects between content, water level detecting portion and the water level are as shown in table 1.
[table 1]
In next process is that washing machine is opened draining valve 74 earlier in rinsing (1) process, and the water of 44 li in interior bucket is discharged from scupper hose 76.Then, the clutch 49 of transmission mechanism portion is switched to the dehydration side, bucket 44 rotated it in the power of motor 48 was delivered to via dehydrating shaft, by applying centrifugal force to clothing, moisture was separated from clothing.Then, after motor 48, clutch 49 all disconnect, carry out water inlet a, make water intaking valve 70 actions of big flow, the high water level of intaking, and CD-ROM drive motor 48 once more, c (S123) running is stirred in beginning rinsing (1), so that cleaning solution is drifted out to come from clothing.
In rinsing (2) process, in the just final rinse cycle, same with rinsing (1), washing machine carries out draining and dehydration earlier, and after these actions all finished, c (S124) running was stirred in beginning rinsing (2).
In addition, rinsing (1) process can be looked what and corresponding omission of the degree of fouling of clothing and laundry amounts.
In dehydration, after rinsing finished, washing machine was opened draining valve 74 earlier the water in the interior bucket 44 is discharged by scupper hose 76.Then, the clutch 49 of transmission mechanism portion is switched to the dehydration side, bucket 44 rotated it in the power of motor 48 was delivered to via dehydrating shaft, by applying centrifugal force to clothing, moisture was separated from clothing.
In the program list of Fig. 3, omitted dehydration drying course afterwards.In drying course, washing machine switches to the washing side to clutch 49 earlier, and to impeller 46, the forward and reverse that impeller 46 carries out rapidly are so that peel off the clothing on bucket 44 inwalls in being close to after the dehydration get off with transmission of power for CD-ROM drive motor 48.Then, impeller 46 carries out forward and reverse, utilize to stir with protuberance 51 collude and tangle clothing and stir on one side, utilize the hot blast air supplying part 61 of drying that hot blast is blown into hot blast squit hole 60 on one side with formations such as fan 55 and heater elements 56.Be blown into the hot blast that interior bucket 44 the insides are come from hot blast squit hole 60, after the water evaporates in the clothing, tube connector 53 is passed from drainage channel mouth 54 then in the inboard of bucket 43 outside interior bucket 44 is discharged to, arrival heat exchanger tube 52.
From clothing, seize the inwall of the hot blast that the contains moisture bucket 43 outside passing behind the moisture and heat exchanger tube 52 when inner, blow the effect of the extraneous air that flows into pressure fan 79 owing to the cooling that is arranged on casing 41 sides, make the outer wall of outer bucket 43 and heat exchanger tube 52 obtain cooling, thereby the inside of bucket 43 and heat exchanger tube 52 can produce moisture dewfall phenomenon outside.That is to say that moist hot blast obtains dehumidifying, and enters circulated air accommodating chamber 59, after passing through filter 64, get back to oven dry fan 55 places again.Utilize this circulation line that hot blast is circulated, just can dry the clothing of 44 li in interior bucket.
