The specific embodiment
Below, with reference to accompanying drawing an embodiment of the present invention is described.In addition, used in the following explanation " on ", the term of D score, " left side " or expression directions such as " right sides " only is in order to let explanation become clear, not limit the present invention at all.In addition, in the following explanation term at used " upper reaches " and/or " downstream " as long as do not specify, all be meant from after the outlet of tank of the sink stated flow to " upper reaches " and/or " downstream " of the flow of liquor of draining control module.
Fig. 1 is the summary construction diagram of the related tumbling-box washing machine of an embodiment.In addition, below the principle of explanation is not limited to tumbling-box washing machine shown in Figure 1, also can be applied to other washing machine (for example, impeller (pulsator) formula washing machine or agitator type washing machine etc.).
Tumbling-box washing machine 1 has basket 2.The set inside of basket 2 has sink 3.Sink 3 is included in the inside of basket 2 and shakes the tank cylindraceous 31 that is supported freely, the swing roller cylindraceous 32 that rotation is supported freely in tank 31 and the motor 33 that makes swing roller 32 rotations.Tank 31 and swing roller 32 have the bottom respectively.Motor 33 is installed in the outside, bottom (outer surface) of tank 31.Be formed with on the tank 31 and be used for discharging the outlet 311 of cleaning solution and the inflow entrance 312 that cleaning solution flows into.Cleaning solution circulates to inflow entrance 312 from outlet 311.
The drying system 6 that also contains in tank 31 water system 4 that supplies water in the basket 2, the cleaning solution tank 31 in is carried out draining or makes drainage system 5 that cleaning solution circulates and send into the hot blast that is used for drying washings to sink 3.In addition, and nonessential drying system 6 arranged.
Tumbling-box washing machine 1 has the guidance panel 8 on the top that is arranged on basket 2 fronts.The user can select the pattern or the various function of the running process (course) of tumbling-box washing machine 1 on guidance panel 8.Guidance panel 8 comprises control circuit portion 81.The display part that control circuit portion 81 is possessed at guidance panel 8 shows the information of user's input.In addition, control circuit portion 81 also can from for example as the liquid level sensor that detects the liquid level in the tank 31, detect optical sensor 72 that the turbidity sensor of the turbidity of cleaning solution uses, or receive detection signals as the electrode sensor 73 that the conductive sensor of the electrical conductivity that detects cleaning solution uses.Begin if set the running of tumbling-box washing machines 1 through guidance panel 8, then control circuit portion 81 is according to these detection signals, controls the draining valve 75 that is possessed in the electromagnetic valve that possessed in the water system 4 or the drainage system 5.By motor 33, water system 4, drainage system 5 and the drying system 6 that control circuit portion 81 controls automatically, set or the control program coordinate operation according to pattern, carry out washing procedure, rinsing process, dehydration procedure and baking operation at least.
Draining valve 75 for example when washing procedure finishes or rinsing process open when finishing.Its result, cleaning solution flow into draining control module 7 from first pipeline 51.Afterwards, be discharged to the outside after the cleaning solution removal that imposed velveteen through filter house 76 is handled.
When draining valve 75 closures, circulating pump 71 work, the cleaning solution in the tank 31 flow into draining control module 7 through first pipeline 51.Afterwards, the dirty composition of cleaning solution is removed through the filter house 76 that is arranged in the draining control module 7.The flow through cleaning solution of filter house 76, the aspiration 711 that is connected through the pump orifice with circulating pump 71 flow in the circulating pump 71.Afterwards, cleaning solution turns back in the tank 31 through second pipeline 52 that the discharge opening with circulating pump 71 is connected.During execution washing procedure or rinsing process, also can carry out the circulation of above-mentioned cleaning solution as required repeatedly.The circulation repeatedly of cleaning solution will help high-quality washing procedure or rinsing process.
The rotating speed of circulating pump 71 can change.If the speed setting of circulating pump 71 gets higher (for example 3500rpm), the cleaning solution that flow in the inflow entrance 312 of tank 31 can move (with reference to the arrow Fi among Fig. 1) along the track in swing roller 32.On the other hand, if the speed setting of circulating pump 71 must lower (for example 1000rpm), flow into cleaning solution in the inflow entrance 312 of tank 31 and will flow between swing roller 32 and tank 31 in the formed space (with reference to the arrow Fo among Fig. 1).
Low speed rotation when circulating pump 71 begins in one of them the operation at least of for example washing procedure and rinsing process.Its result does not have the washing agent of dissolving or the softener of the high concentration after the firm input of softener to be scattered on the washings in the swing roller 32 in the time of can suppressing to wash end.
The cleaning solution that flow in the space between swing roller 32 and the tank 31 is discharged to drainage system 5 from outlet 311, and turns back to the inflow entrance 312 (circulating process in the tank) of tank 31 once more.Through circulating process in the tank repeatedly, thereby promote the dissolving of washing agent and/or the concentration of softener to become even.Thus, can avoid problem preferably because of the stain of the caused washings of softener of the washing agent or the high concentration that do not have dissolving.
Circulating process is set at water supply operation in washing procedure for example and/or the rinsing process and carries out after about 10 seconds comparatively desirable in the tank.Replace, circulating process also can begin when the liquid level that for example detects from the about 40mm in lower end of tank 31 in the tank.Its result, can suitably avoid circulating pump 71 cleaning solution fully be not filled in the circulating pump 71 during work.Like this, can avoid by the caused abnormal sound of cavitation (cavitation) of circulating pump 71, by the abnormal temperature and the work of circulating pump 71 under abnormal temperature of the not enough caused circulating pump 71 of amount of liquor.
Tumbling-box washing machine 1 also can possess the pump to tank 31 supply bath waters.Circulating process also can be performed after pump is fed to bath water in the tank 31 in the tank.Thus, bath water supplies the not action simultaneously of using pump and circulating pump 71, thereby suppresses to bring unhappy huge generation of noise to the user.
Also can set the reservation running to tumbling-box washing machine 1 through the operation of guidance panel 8.When tumbling-box washing machine 1 reservation running, circulating process can for example carry out during at ordinary times 2 times long in the tank.Its result, can reservation during standby (from behind the book setting to tumbling-box washing machine 1 actual till beginning to move during) dissolving cured preferably washing agent.Thus, can during the reservation running, obtain sufficient cleaning force, and reduce undissolved detergent amount.
Tumbling-box washing machine 1 also can possess temperature sensor as required.Also can change the time of implementation length of circulating process in the tank according to the temperature of the cleaning solution that utilizes temperature sensor measurement to arrive.For example, when the temperature that detects cleaning solution when temperature sensor is 5 ℃, the double time span when circulating process is performed the temperature that for example detects cleaning solution and is 20 ℃ in the tank.Its result, even under low water temperature, washing agent also can fully dissolve.

Figure 10 is the skeleton diagram of terminal board 731.Figure 10 (a) is the side view of terminal board 731.Figure 10 (b) is the front view of terminal board 731.Simultaneously with reference to Figure 10, Fig. 3 and Fig. 6.In addition, shape and the big I in conjunction with the terminal board 732 in the downstream of Fig. 2 to Fig. 6 explanation is identical with terminal board 731.
On the face of the opposite side of the overbending direction with edge part 735,736 of terminal board 731, be formed with discoideus heavy section 738 and columned electrode part 739.Terminal board 731 is connected with the base end part of electrode part 739 through heavy section 738.Chimeric on the base end part of electrode part 739 have an O type ring 371.Electrode part 739 is inserted on the straight sections 701 of basket 70 of draining control module 7 in the formed through hole 773 (with reference to Fig. 2).
Be formed with a pair of through hole 310 on the terminal board 731.The through hole 310 of one of them is positioned at the top of electrode part 739.Another through hole 310 is positioned at the below of electrode part 739.A pair of through hole 310 is arranged with electrode part 739 along the vertical direction.The line parallel of the central point of folding line 734 and a pair of through hole 310 of binding.Be inserted with the fixture of bolt and so in the through hole 310.Like this, through hole 310 is installed in terminal board 731 fixed part on the outside of straight sections 701 and brings into play function as being used for.
If utilize fixture that terminal board 731 is crimped on the outside of straight sections 701, the O type ring 371 that then is installed on the base end part of electrode part 739 is compressed.The restoring force of O type ring 371 and the fixture that inserts in the through hole 310 make terminal board 731 produce bending moment.Left and right edges through making terminal board 731 bends along the folding line that in the orientation of a pair of through hole 310, extends, and terminal board 731 has higher rigidity with respect to bending moment.Therefore, terminal board 731 can be fixedly mounted on the outside of straight sections 701.Its result, the O type ring 371 of base end part that is arranged on electrode part 739 is because of the effect that receives stronger power is compressed, thus the performance high sealing performance.Like this, can suppress cleaning solution aptly leaks through formed through hole 773 on the straight sections 701.In addition, in this embodiment, folding line 734 is vertical with the axle of bending moment, but the angle of reporting to the leadship after accomplishing a task of the axle of folding line 734 and bending moment does not have special qualification.In addition; In this embodiment; Through hole 310 is shown as fixed part; But also can replace, adopt and for example to utilize anchor clamps (clamp) terminal board 731 to be crimped on the fixedly gimmick of the outer wall of straight sections 701, or adopt in order to make the environment-development of O type wave sealing function other fixing gimmicks that can terminal board 731 be crimped on the outer wall of straight sections 701 with enough big power.In addition, when using anchor clamps, terminal board 731 brought into play function by the part of anchor clamps clamping as fixed part.
Figure 11 is the cutaway view that the straight sections 701 of terminal board 731,732 is installed.Figure 11 (a) is positioned at the terminal board 731 of the upper reaches one side and the cutaway view around the electrode part 739.Figure 11 (b) is positioned at the terminal board 732 of downstream one side and the cutaway view around the electrode part 739.
The cleaning solution that the smooth inner face 772 of crosscut straight sections 701 is contained in the inner outstanding electrode part 739 of straight sections 701 and straight sections 701 contacts.Apply high-frequency ac voltage through 733 pairs of terminal boards of electric wire 731,732, the electrical conductivity of existing cleaning solution between the pair of electrodes portion 739 (impedance (impedance)) is able to measure.
Figure 12 is the sketch map that flows of the cleaning solution around the electrode part 739.In addition, among Figure 12, to the electrode part label symbol 739a at the upper reaches, to the electrode part label symbol 739b in downstream.
Shown in figure 12, the 739a of pair of electrodes portion, 739b are along the length direction alignment arrangements of straight sections 701.By the plane P that defines of the 739a of pair of electrodes portion, 739b and an almost parallel of straight sections 701.The electrode part 739a at the upper reaches will be along the moving cleaning solution above-below direction shunting of the axial flow of straight sections 701.The flow of the cleaning solution of therefore, crosscut plane P reduces.Its result, in the electrode part 739a of the electrical conductivity that is suitable for measuring cleaning solution, the space (the for example space more than the 15mm and below the 30mm) between the 739b, the flowability of cleaning solution reduces.Like this, can obtain to be suitable for to measure the flowing of cleaning solution of electrical conductivity.
In addition, shown in figure 12, the plane P that comprises the axle of the 739a of pair of electrodes portion, 739b is a horizontal plane.Comparatively it is desirable to; All (space that air trapping might take place because of the design reasons of draining control module 7 (for example on the top, inner space of not crosscut straight sections 701 for the 739a of pair of electrodes portion, 739b; And the bottom, inner space of straight sections 701 (might pile up the space (for example, the zone of the downside 1/5 in the inner space of straight sections 701) of dirty composition because of the design reasons of draining control module 7) zone of the upside 1/5 in the inner space of straight sections 701)).Its result, whole of the ledge of electrode part 739a, 739b with straight sections 701 in cleaning solutions contact.Therefore, the air in the straight sections 701 is inhibited to the influence of the measurement of electrical conductivity.In addition, when electrode part 739a, 739b protruded in the zone of the upside 4/5 in the inner space of straight sections 701, the dirty compositions of piling up in the straight sections 701 can be inhibited to the influence of the measurement of electrical conductivity.
Figure 13 schematically shows flowing of optical sensor 72 and electrode sensor 73 cleaning solution on every side.Shown in Figure 13 is to combine Fig. 7 to Fig. 9 and the light-emitting component 721 of the optical sensor 72 explained and the light path 250 of the IR between the photo detector 722.In addition, identical with Figure 12, to being arranged at the electrode part label symbol 739a of the upper reaches one side, to being arranged at the electrode part label symbol 739b of downstream one side.
The upstream-side-end 277 of the smooth inner face 772 that forms at the internal face of straight sections 701 for the unnecessary refraction of the IR that prevents to form light path 250 is from other internal face protuberance.Therefore, upstream-side-end 277 confuses flow of liquor.Therefore, entirely arrive light path 250 in order to make flow of liquor, upstream-side-end 277 is formed on fully away from the position of the upper reaches one side of light path 250 comparatively desirable.At this moment, the cleaning solution of crosscut light path 250 becomes the flow of the measurement of the turbidity that is suitable for cleaning solution, and wherein, the turbidity of cleaning solution is according to the light quantity of the IR of the photo detector 722 of the optical sensor 72 that arrive to combine Fig. 7 to Fig. 9 to explain and estimative.The IR of optical sensor 72 can not bring any influence to cleaning solution mobile.Therefore, the flow of liquor after the rectification arrives electrode part 739a, 739b.
As combine Figure 12 illustrated, shunt up and down by the part of flow that the electrode part 739a at the upper reaches will be parallel with the direction of principal axis of straight sections 701.Its result, flow of liquor is confused.Downstream one side that by the confusion of the caused flow of liquor of electrode part 739a is the optical sensor 72 explained combining Fig. 7 to Fig. 9 produces, and therefore can bring influence to the measurement of the turbidity of optical sensor 72 hardly.
As combine Figure 12 illustrated, by the plane P that defines of electrode part 739a, 739b and an almost parallel of straight sections 701.Therefore; For example; When making cleaning solution in straight sections 701, reflux (from the direction of straight sections 701) towards the outlet 311 (with reference to Fig. 1) of tank 31; Though electrode part 739b shunts flow of liquor up and down, owing to electrode part 739a overlaps with electrode part 739b on the flow direction of cleaning solution, so can not confuse to transition flow of liquor.Therefore, even when cleaning solution refluxes, also can be to pass through the turbidity of the cleaning solution of light path 250 than higher accuracy detection.

Shown in Figure 17 is the structure of the connecting portion of the tank 31 and second pipeline 52.Figure 17 (a) is the vertical view that constitutes the pipe portion (duct) of connecting portion.Figure 17 (b) is the sectional elevation of the pipe portion shown in Figure 17 (a).Figure 17 (c) is the longitudinal section of the pipe portion shown in Figure 17 (a).
The inflow entrance 312 of tank 31 is formed to the outstanding ring-type flank 121 in top by the outer wall from tank 31.Inner peripheral surface along ring-type flank 121 is provided with O type ring 122.O type ring 122 is pushed by pipe portion 520.
Set inside at tank 31 has swing roller 32.Be provided with barrier 126 on swing roller 32 and between the inflow entrance 312.Barrier 126 is supported by the connecting wall 127 that the outer wall with tank 31 is connected.Barrier 126 forms narrow and small stream with amount of decrease wall 123.This narrow and small stream is brought into play function as the jet 129 of jet washing liquid to sink 3 in.
Through the cleaning solution of the jet 129 that forms by barrier 126 and amount of decrease wall 123, be supplied to the inside of swing roller 32 subsequently through the stream 281 of formation between the front bulkhead 321 of the front bulkhead 128 of the part of the outside that constitutes tank 31 and swing roller 32.Front bulkhead 128 is pushed O type ring 122 with 123 cooperations of amount of decrease wall.
The front bulkhead 128 of tank 31 and the front bulkhead of swing roller 32 321 form the export department 282 of ring-type.Passed through the cleaning solution of stream 281, sprayed to the rotary middle spindle of swing roller 32 through the export department 282 of ring-type.The cleaning solution that sprays through export department 282 sprays to the inboard rotary area of swing roller 32 efficiently.Like this, irrelevant with the amount that is housed in the washings in the swing roller 32, cleaning solution is supplied with washings efficiently.
(forming the face of stream 281) has inclined plane 283 and flexure plane 284 in the inside of the front bulkhead 128 of tank 31.The inclined plane 283 that the sectional area of stream 281 is reduced downstream gradually increases the flow velocity of the cleaning solution through stream 281 gradually.Therefore, while the cleaning solution through stream 281 quickens to flow to flexure plane 284.Flexure plane 284 makes the flow direction of cleaning solution change into the direction towards the bottom of swing roller 32.The flow of liquor of therefore, spraying from export department 282 is to the bottom of swing roller 32.Its result, cleaning solution is supplied with washings efficiently.
The simple mounting structure of outer cover 524 usefulness of conduit 520 forms the stream towards inflow entrance 312.Cover shape and size, the shape of connecting wall 127 and the shape and the size of size and barrier 126 of the outer cover 524 of inflow entrance 312 through regulation suitably, can realize the inflow of suitable cleaning solution in swing roller 32.Through suitably stipulating the design parameter of outer cover 524, connecting wall 127 and barrier 126, can suitably confirm from flow width, flow thickness and the liquid flowing speed of the cleaning solution of jet 129 injections.Like this, irrelevant with the amount that is housed in the washings in the swing roller 32, cleaning solution is supplied with washings efficiently.
The very simple structure of the mounting structure of the outer cover 524 of conduit 520 shown in Figure 17 or connecting wall 127 and barrier 126 not only suppresses to leak but also help to reduce manufacturing cost.
As stated, conduit 520 utilizes the stream that second pipeline 523 and outer cover 524 form towards inflow entrance 312.As shown in Figure 1, conduit 520 formed streams extend along the outside of tank 31.Therefore, use the smooth pipeline with square-section of second pipeline 523 and outer cover 524, be formed in the narrow and small space between tank 31 and the basket 2.Smooth pipeline regulation is suitable for the flow of liquor that flow is wide and flow is thick of the shape/size of jet 129.Cleaning solution through smooth pipeline by rectification after towards jet 129.
On the front bulkhead 321 of swing roller 32, be formed with a plurality of prominent bars 322.Prominent bar 322 extends in the scope of designated length along the Zhou Fangxiang of the front bulkhead 321 of swing roller 32.A plurality of prominent bars 322 in the position of Zhou Fangxiang and/or the position of radial direction also can be different.Prominent bar 322 reduces the sectional area of stream 281 in the downstream of jet 129 locally.When near export department 282, flow path cross sectional area being reduced, when through prominent bar 322 flow path cross sectional area being reduced, be different from the motion track of the cleaning solution of export department's 282 ejections at the position of departing from export department 282 through prominent bar 322.Therefore, scatter in the scope of the broadness of cleaning solution swing roller 32 in of discharging from export department 282, thereby realization is supplied cleaning solution efficiently to washings.
The shape of prominent bar 322 is not limited to shape shown in Figure 17.For example, prominent bar 322 can shape in wave shape, also can be the blade shaped shape.Also can adopt the prominent bar 322 of the arbitrary shape of the motion track that can change the cleaning solution of discharging from export department 282.In addition, also can adopt the configuration of prominent bar 322 of the arbitrary shape of the motion track that can change the cleaning solution of discharging from export department 282.
Between barrier 126 and swing roller 32, be formed with space 266.When circulating pump 71 low-speed runnings (for example 1000rpm), cleaning solution is from jet 129 inflow spaces 266.The cleaning solution that flows into space 266 is through the outlet 311 of the spatial flow between swing roller 32 and the tank 31 to tank 31.
Figure 18 illustration goes out the functional structure of control circuit portion 81.
Judging part 814 from operational part 813 receive washing procedures and/or rinsing process time started and/or; The information in the elapsed time of washing procedure and/or rinsing process; Transmit control signal to circulating pump 71, make circulating pump 71 during the designated duration of washing procedure and/or rinsing process in running off and on.Receive the intermitten that the circulating pump 71 of control signal turns round repeatedly and stops.
Figure 19 is illustrated in the diagram of the signal that circulating pump 71 carries out during the intermitten sending from optical sensor.Signal when big of spuming of Figure 19 (a) expression cleaning solution from optical sensor.The signal that spumes hour of Figure 19 (b) expression cleaning solution from optical sensor.In Figure 19, the longitudinal axis in left side is represented the rotating speed of circulating pump 71, and the longitudinal axis on right side is represented the output from optical sensor 72 with bit.In addition, expression is the mean value of 5 samplings from the each point of the output of optical sensor 72 in the diagram.
Before explanation data shown in Figure 19, the principle from the change of the output of optical sensor 72 is described.When the turbidity of cleaning solution was hanged down, the light ratio turbidity that the photo detector 722 of optical sensor 72 receives was more when higher.Therefore, when the turbidity of cleaning solution is hanged down, compared more electric current when higher with turbidity and flow through photo detector 722, the voltage that is applied to like this in the impedance descends.Its result, the output of optical sensor 72 reduces.When the turbidity of cleaning solution is higher, when the light ratio turbidity that the photo detector of optical sensor 72 722 receives is low still less.Therefore, when the turbidity of cleaning solution was higher, the electric current of comparing still less when low with turbidity flow through photo detector 722, and the voltage that is applied to like this in the impedance rises.Its result, the output of optical sensor 72 improves.
Data shown in Figure 19 are described below.Shown in figure 19, the output of optical sensor 72 synchronously changes with the intermitten of circulating pump 71 basically.When the rotating speed of circulating pump 71 increased, the output of optical sensor 72 also increased.When circulating pump 71 stopped, the output of optical sensor 72 reduced.Can know that from the comparison of Figure 19 (a) and Figure 19 (b) when cleaning solution spumed greatly, the amplitude that the output of optical sensor 72 changes increased.Because the foam of cleaning solution makes the IR diffusion from the light-emitting component 721 of optical sensor 72, therefore, when the foam output of optical sensor 72 for a long time increases.On the other hand, reduce when the foam output of optical sensor 72 after a little while.When circulating pump 71 runnings, in straight sections 701, produce more foam from current.Its result, the foam that in straight sections 701, flows becomes many.Owing to be flowing in the light diffusion that straight sections 701 interior foams make optical sensor 72, therefore, have less electric current to flow through photo detector 722.As stated, owing to when less electric current flows through photo detector 722, be applied to the voltage rising in the impedance, so the output of optical sensor 72 increases.On the other hand, when circulating pump 71 stops, owing to the mobile of cleaning solution weakens, so the foam in the straight sections 701 is floating to the top.Its result reduces the amount of foam of the light diffusion of optical sensor 72.Therefore, the voltage that when more electric current flows through photo detector 722, is applied in the impedance descends.Like this, the output of optical sensor 72 reduces.So, the degree foamy of cleaning solution is directly related with the amount of diffusion of the light of optical sensor 72, thereby is defined as the foam volume of the light diffusion that makes optical sensor 72.
Operational part 813 shown in Figure 180 is poor (below be called output poor) of the output of the optical sensor 72 of output and circulating pump 71 stopping periods of the optical sensor 72 between 71 on-stream periods of computation cycles pump for example.At this, also can be with being defined as " service cycle " with stopping period between the on-stream period of circulating pump 71.In order to reduce the influence that is included in the noise (noise) in optical sensor 72 outputs, can the output difference that calculate in each service cycle be averaged.Judging part 814 can compare the threshold value of the output difference that for example is kept at the optical sensor 72 in the storage part 816 and the result of calculation of operational part 813, judges the degree foamy of cleaning solution.Through with the comparison of the threshold value of the output difference that averages out, can reduce the influence of noise to judgement foamy.In addition, poor only for the output of the optical sensor 72 of output that fixes on the optical sensor 72 between 71 on-stream periods of computation cycles pump and circulating pump 71 stopping periods not based on the computing of operational part 813.Also can replace, carry out other computing, in the time of for example can calculating circulating pump 71 entrys into service or the computing of the size of the output of the rate of change of the output of the optical sensor 72 after just having stopped or optical sensor 72 change.
In the storage part 816 that control circuit portion 81 is possessed, can store the output difference that for example is used as optical sensor 72 lower threshold first threshold and be used as second threshold value of the upper limit threshold of said output difference.Judging part 814 takes out the first threshold and/or second threshold value from storage part 816, the output difference of the optical sensor 72 that operational part 813 is calculated and first threshold and/or second threshold value compare.When the output difference of optical sensor 72 when first threshold is following, judging part 814 transmits control signal to the electromagnetic valve of water system 4, make output when in washing procedure and/or rinsing process, supplying water than the output difference of optical sensor 72 during greater than first threshold still less.Like this, can supply unwanted water, thereby realize suitable water saving.When the output difference of optical sensor 72 when second threshold value is above, judging part 814 transmits control signal to the electromagnetic valve of water system 4, makes output when in washing procedure and/or rinsing process, supplying water more during less than second threshold value than the output difference of optical sensor 72.Like this, the liquid level of the cleaning solution in the sink 3 rises, and washing procedure and/or rinsing process are performed under suitable state foamy.
Figure 20 is the figure about the data structure of the upper limit threshold of the output difference of optical sensor 72 and lower threshold that illustrates that storage part 816 had.Come together to illustrate kind, judge the method for the foam of cleaning solution with different threshold values according to washing agent with reference to Figure 18, Figure 20.
Shown in figure 20, storage part 816 stores different upper limit thresholds and lower threshold to the output difference of optical sensor 72 by the washing agent kind.Storage part 816 also store in advance with the water supply operation of washing when beginning in the relevant data of variation of output of output and optical sensor 72 of electrode sensor 73 of every kind of washing agent.Begin through after the fixed time from water supply, control circuit portion 81 transmits control signal to circulating pump 71 and lets circulating pump 71 work.During circulating pump 71 work, operational part 813 stores the output of electrode sensor 73 and optical sensor 72 into storage part 816 in each fixed time.Judging part 814 will be stored in advance in the storage part 816 data and through operational part 813 output of stored electrode sensor 73 and optical sensor 72 compares, judge the kind of washing agent.Judged result is stored in storage part 816.But, for powder detergent that contains zeolite and the liquid detergent that does not generally contain zeolite because it is high to contain the white turbidity of powder detergent of zeolite, therefore, also can be only through optical sensor 72 output relatively judge powder detergent and liquid detergent.
For example, suppose that the washing agent with " A1 " expression is a powder detergent among Figure 20, the washing agent that reaches " A3 " expression with " A2 " is a liquid detergent.At this moment, comparatively it is desirable to, will set to the upper limit threshold UL1 that washing agent A1 distributes the upper limit threshold UL2 or the UL3 that distribute greater than the washing agent A2 that gives other or A3.When judging part 814 was judged employed washing agent and is powder detergent, judging part 814 was read upper limit threshold UL1 from storage part 816, and operational part 813 compares the output difference and the upper limit threshold UL1 of the optical sensor that calculates 72.When the output difference of optical sensor 72 during greater than upper limit threshold UL1 or when upper limit threshold UL1 is above, transmit control signal to the electromagnetic valve of water system 4.Its result compares with other washing agent, can control water saving and carry out rinsing process.Therefore, to powder detergent higher as basicity, that contain the zeolite suitable rinsing condition is provided.
In addition, judging part 814 can be a powder detergent or for after the liquid detergent judging employed washing agent also, judges the degree foamy of washing agent liquid according to the output of optical sensor 72.Also can further adopt a kind of sequence (sequence); When judging washing agent and be liquid detergent; Electromagnetic valve to water system 4 transmits control signal, and output when supplying water is reduced during for powder detergent than washing agent.Though sometimes according to the amount of washing agent; The degree of when powder detergent and liquid detergent, being judged by optical sensor 72 foamy is a same degree; But through above-mentioned determining program and sequence, even the identical water saving that also can realize of degree foamy according to the washing agent kind.In addition, also can be when judging employed washing agent and be liquid detergent, longer when making time of implementation of washing procedure be powder detergent than washing agent.
In above-mentioned explanation; The electrode sensor 73 of measuring electrical conductivity is illustrated as giving prominence to the sensor in stream; But above-mentioned principle is not limited thereto, and also can be applicable to use the tumbling-box washing machine of any sensor that must directly contact with cleaning solution for the physical characteristic that detects cleaning solution.
In above-mentioned explanation, optical sensor 72 is the turbidities that are used to measure cleaning solution, but also can be used for other measurement purpose.Above-mentioned principle also goes for being used for detecting the optical sensor 72 of the accumulation of dirty composition, maybe can utilize optical sensor 72 and other the physical characteristic or the environmental change of being measured aptly.
In above-mentioned explanation, as the for example clear pump of the flow device that cleaning solution is flowed, but also can replace, utilize the screw that is arranged in circulation road or the stream etc. and cleaning solution is flowed.
Also can be substituted in this embodiment as drainage arrangement and by illustrational draining valve, utilize the device arbitrarily that can open and close discharge pipe line 74 as drainage arrangement according to the signal of telecommunication.And, also can replace as water supply installation and by illustrational electromagnetic valve, utilize the device arbitrarily that can open and close supply channel 41 as water supply installation according to the signal of telecommunication.
Mainly comprise washing machine in the above-mentioned embodiment with following structure.
A kind of washing machine involved in the present invention comprises: the sink that possesses cleaning solution inflow entrance that flows into and the outlet of discharging cleaning solution; The pipeline that is connected with said outlet with said inflow entrance; The flow device that said cleaning solution is flowed to said inflow entrance through said pipeline from said outlet; Detect the optical sensor of the light quantity that sees through the cleaning solution in the said pipeline; And according to the control part of the detection signal of said optical sensor control washing action, wherein, said optical sensor detects and exports first light quantity and second light quantity of said flow device stopping period between said flow device on-stream period.
According to above-mentioned structure, after the cleaning solution that in sink, is stirred out foam was discharged to pipeline from the outlet of sink, the inflow entrance from sink turned back in the sink once more.Even owing to the foam in the cleaning solution that in sink, produces can not disappear in pipeline yet at once, and therefore influence, can measure the degree foamy of cleaning solution preferably through the amount of the light of cleaning solution through optical sensor.First light quantity between the on-stream period of light sensors flow device and second light quantity of flow device stopping period, and will export control part to the detection signal of first light quantity and second light quantity.Control part is judged degree foamy according to detection signal, controls the washing action.Therefore, control part need not wait for that lather collapse in the cleaning solution can judge the degree foamy of cleaning solution.And, along with the shortening of judgement time, control part judge during water be difficult for being replenished.Like this, judgement foamy is not vulnerable to the influence of supplementing water.Can be very soon and correctly detect the washing machine of the degree foamy of cleaning solution thereby provide.
In above-mentioned structure, comparatively it is desirable to, said control part is controlled said washing action according to judging the degree foamy of said cleaning solution to the detection signal of said first light quantity with to the difference of the detection signal of said second light quantity.
According to above-mentioned structure, according to the detection signal of first light quantity and poor to the detection signal of second light quantity, control part is judged the degree foamy of cleaning solution, controls the washing action.Therefore, do not need complex calculations or signal to handle and to judge degree foamy.Thereby can further detect the degree foamy of cleaning solution soon and correctly.
In above-mentioned structure; Comparatively it is desirable to also comprise the water supply installation that supplies water to said sink; Said control part possesses the storage part of storage to the first threshold of said difference; When said difference is said first threshold when following, said control part control said water supply installation make output from said water supply installation less than said difference the output during greater than said first threshold.
According to above-mentioned structure, when the first threshold of in storage part, being stored when the difference of the detection signal of optical sensor was following, control part control water supply installation reduced the output from water supply installation.The difference of the detection signal of optical sensor is more little, and the degree foamy of cleaning solution is more little.The degree foamy of cleaning solution hour, needed output is little.Therefore, when the difference of detection signal when first threshold is following, can suppress unwanted water supply through reducing output.The water-saving result that like this, can obtain to suit.
In above-mentioned structure; Comparatively it is desirable to; Said storage part is also stored second threshold value greater than said first threshold; When said difference when said second threshold value is above, the output when said control part is controlled said water supply installation and made from the output of said water supply installation greater than said difference less than said second threshold value.
According to above-mentioned structure, when second threshold value of in storage part, being stored when the difference of the detection signal of optical sensor was above, control part control water supply installation increased the output from water supply installation.The difference of the detection signal of optical sensor is big more, and the degree foamy of cleaning solution is big more.When the degree foamy of cleaning solution was big, needed output was big.Therefore, when the difference of detection signal when second threshold value is above, can be through increasing output as required to sink supply more water.Like this, can realize being suitable for the suitable washing action of washings.
In above-mentioned structure; Comparatively it is desirable to; The data of the corresponding relevant light quantity of washing agent kind that is contained in said storage portion stores and the said cleaning solution; Said control part will compare from the output signal and the said data of said optical sensor; Judge washing agent kind contained in the said cleaning solution; Said second threshold value comprises corresponding the 3rd threshold value when being powder agent with said washing agent kind, and said control part is when judging said washing agent kind and be powder detergent, and the output when said difference is controlled said water supply installation and made from the output of said water supply installation greater than said difference less than said the 3rd threshold value when said the 3rd threshold value is above.
According to above-mentioned structure, control part is also judged washing agent kind contained in the cleaning solution except the degree foamy of judging cleaning solution.Judging washing agent kind contained in the cleaning solution when control part is that the difference of the detection signal of powder detergent and optical sensor when above, is being carried out some more water supply with the 3rd threshold value stipulated for powder detergent.Therefore, the basicity of cleaning solution and the concentration of the zeolite in the cleaning solution are reduced.Like this, can suppress the damage of washings aptly.
