The invention is characterized in, at a high speed wind is directly blown on clothing, flatten the fold that results from the clothing with the power of wind.For this reason, needs produce the blowing unit 28 of wind at a high speed and this wind are directly blown the warm wind outlet 32 on clothing.For the required performance of blowing unit, the narration in the back.Use Fig. 7, Fig. 8 that the detailed content of warm wind outlet 32 is described.Fig. 7 is the front view that warm wind outlet 32 is provided with the outer bung 2d of portion, and Fig. 8 is the cutaway view that cuts off the warm wind outlet of representing 32 with double dot dash line A-A at Fig. 7.
And, if the overhang of the 32a of export department is too much, the motion of the clothing when then hindering washing with drying, therefore as shown in Figure 7, nozzle is made flat kerf reduce overhang, and the surface configuration of peristome 2c and the 32a of export department is changed smoothly.In addition, runner 32b and runner 32c make the variation of no unnecessary projection and rapid flow direction, and reduce gradually to nozzle 32d flow area.Through like this, can reduce the pressure loss and the fluid sound that when at a high speed distinguished and admirable crosses runner 32b, 32c, produce.
Flowing as follows of wind during dry operating.If running blowing unit 28, and, then in washing and dewatering bucket 3, be blown into warm wind (arrow 41) at a high speed, blow on the moist clothing, the clothing and of heating from the clothing transpiring moisture from nozzle 32d to heater 31 energising.Become the how wet through holes of air on being located at washing and dewatering bucket 3 of high temperature and flow to outer bucket 2, suck in the dry channel 29 from air entry 2a, and in dry channel 29 mobile (arrow 42) from the bottom up.On the wall of dry channel 29, flow down cooling water from the water-cooled desiccant body, the air that high temperature wets more becomes dry Cryogenic air and gets into filter passage 27 (arrows 43) through contact the dehumidifying that is cooled with cooling water.Gauze filter 8a through being located on the filter passage 27 removes the end of a thread, and gets into air intake passage 33, is drawn into blowing unit 28 (arrow 44).And, heat once more with heater 31, be blown in the washing and dewatering bucket 3, circulate with this.
Fig. 9 is the example of having investigated in the occasion of having carried out aforesaid dry operating from the result of the quality condition of the wind speed of nozzle 32d ejection and dried clothing.Wind speed and air quantity are regulated through the revolution of change motor 28a and the area of nozzle 32d.In addition, wind speed is the value that the result according to the flow pressure characteristic of having measured blowing unit 28 calculates.The flow pressure characteristic is measured with device shown in Figure 10.On the outlet of the air entry of surge tank and blowing unit 28, throttle orifice is installed; When the revolution to the diameter of throttle orifice and motor 28a carries out various changes, measure flow and the air entry of blowing unit 28 and the pressure of outlet, obtained the flow pressure characteristic.And, measure the air entry of the blowing unit 28 when being installed in blowing unit 28 on the scrubbing-and-drying unit and the pressure of outlet, obtained flow according to above-mentioned flow pressure characteristic, with value that this flow is removed with nozzle area as wind speed.
Experiment condition is shown in figure, and testing machine is the drum-type washing drying machine with washing and dewatering bucket of diameter 600mm and volume 75L, and the cloth amount is 2kg.The evaluation of quality is carried out with various clothings, but has represented the cotton pyjama result that fold is the thinnest.Evaluation is the sense evaluation according to the 5 visual stages, will represent with Figure 11 the example of the quality condition of sense evaluation of estimate.Top nozzle is the occasion (the right oblique upper position of outer bung 2d) that on above-mentioned position, is provided with nozzle 32d, and following nozzle is arranged on the occasion of the bottom of outer bung 2d.Make from the blow-off direction of the wind of nozzle 32d roughly towards the diapire central authorities of washing and dewatering bucket 3.The result is 3 estimators' a mean value.
From figure, can know: (A) improve along with wind speed uprises quality.But if the too high then deterioration conversely of wind speed is (according to top nozzle 1.5m
3The data of/min);
(B) if the many side's better quality of the identical then flow of wind speed, but flow 1.5m
3/ min and 1.7m
3The difference of/min is less;
(C) if, then descend the quality of nozzle better than top nozzle with identical wind speed, flow-rate ratio.
Like this, though the high more then quality of wind speed is good more, and preferably flow is also some more.Therefore, not to strengthen a certain side, but consider that preferably both balances set.Specifically; Need not merely consider quality; Also to consider the passage that current value (in the occasion of home-use source power supply, blowing unit 28 amounts to below the 15A with heater 31, motor 4, control device 38 electricity consumptions) and drying property, wind are circulated flow area, decide wind speed and flow to the installation of scrubbing-and-drying unit etc.
If the sense evaluation of estimate is more than 4, even it is discontented also few then directly to wear dried clothing.For the sense evaluation of estimate is reached more than 4,, be necessary that at flow be 1.5m in the occasion of top nozzle
3Wind speed is more than the 90m/s during/min, but owing to there is the tendency as if the too high then deterioration of wind speed, therefore, the highest also will being suppressed at about wind speed 130m/s is advisable.In addition, best in quality at wind speed 100～120m/s.Occasion at following nozzle is necessary that at flow be 1.5m
3Wind speed is more than the 60m/s during/min, but because almost constant at the above quality condition of 80m/s, therefore, maximum is also to be advisable about 80m/s.Be used for producing the nozzle area of above-mentioned wind speed, be combined into 190～280mm in the field of top nozzle
2, be combined into 310～415mm in the field of following nozzle
2The performance that therefore, on blowing unit 28, need make above-mentioned flow be enough to flow through from the nozzle of above-mentioned area.In this embodiment example, nozzle location is that top nozzle and nozzle area are 250mm
2(incision-like of width 50 * height 5mm), blowing unit 28 its blast fan diameters are that 140mm, vane thickness are that 7mm and revolution are that per minute 16000 changes.The fan discharge pressure becomes about 7500Pa (air themperature 30 ℃ time) thus, is about 1.5m at flow
3Obtain being about the wind speed of 100m/s during/min.
In the occasion of the clothing that has been not easy fold, also can obtain the quality of sense evaluation of estimate more than 4 with the value lower, but generally be dry various clothings of while, so be advisable with clothes merging that plays fold easily and decision wind speed than above-mentioned wind speed.
Use Figure 12 to explain that the wind through will be at a high speed reduces the reason of clothing fold to the clothing.Figure 12 (a) is wind 41 from the high speed of the nozzle 32d ejection ideograph during with the clothing collision.At this, there is the situation of other clothing at the back side that is illustrated in clothing.If the collision of wind and clothing, then on clothing, do in order to the open power of wind (arrow (1)) and by with clothing collision back change flow direction along the power (arrow (2)) of the wind direction stretched of clothing Surface runoff.Flatten the fold of clothing with the power of being somebody's turn to do (1) and (2).The occasion that the amount of the clothing in washing and dewatering bucket 3 is many having a lot of other clothings and can not freely-movable around the clothing that directly blows to wind, therefore mainly flatten fold with the power of (1).In the few occasion of the amount of clothing, the clothing freely-movable, the clothing that blows to wind becomes the wind long narrow flag when aweather flow direction flattens such, and by flattening fold along the power of the wind of clothing Surface runoff caused (2).In the few occasion of the amount of clothing, clothing launches in the drying, is difficult to produce fold, so in the power of this consideration (1).
(1) power F, shown in Figure 12 (b),, then proportional with amassing of Q and V if the flow of the wind that will blow out from nozzle 32d is made as Q, wind speed is made as V.In addition, if the distance of nozzle 32d and clothing is made as X, then power F and V proportional, and X be inversely proportional to.But, the very near occasion of the distance of nozzle 32d and clothing (in the central area of jet flow, the occasion of round nozzle, from nozzle to 6 times the position that is about nozzle diameter), then F and V are proportional and irrelevant with X.Therefore,, increase flow Q or increase wind speed V, perhaps reduce X and get final product (making clothing) near nozzle in order to strengthen F.Quality results shown in Figure 9 can be explained in view of the above.
In order to increase flow Q, need the revolution of the fan of raising blowing unit 28, or increase the external diameter and the blade height of fan.And it is relatively good that the area that strengthens the passage that warm wind passes through reduces the pressure loss.Especially, make the occasion of the water-cooling pattern of water,, then produce the phenomenon that cooling water is blown to four winds if the flow velocity of flow air is too fast in dry channel 29 in dehumidifying.If cooling water arrives filter 8a and heater 31, then, therefore must strengthen the flow area of dry channel 29 owing to cause the significantly reduction of drying efficiency.Therefore,, the size of passage and blowing unit is maximized, cause the maximization of the size of cabinet 1, thereby be difficult in the family the scrubbing-and-drying unit setting if increase considerably flow.
On the other hand, in order to increase wind speed V, blowing unit 28 made the pressure-type blowing unit and reduce nozzle area get final product.In the occasion of using general turbofan as blowing unit 28; The method that makes the method for blast fan ever-larger diameters and under the little situation of the diameter that still keeps blast fan, improve revolution with low revolution is arranged, and at a high speed rotationization have can be installed in identical in the past cabinet on advantage.
From the experiment structure of quality shown in Figure 9, found if the phenomenon of the too high then deterioration of wind speed.This is with foregoing illustrative not.If the motion of the clothing in the observation experiment can be known if wind speed is too high then because the impetus of wind produces the phenomenon of twisting like clothing.The reason of deterioration that therefore, Here it is.
In order to reduce the distance X of nozzle 32d and clothing, clothing must be provided with nozzle 32d and gets final product near part when drying.Therefore, the position of nozzle 32d is arranged on position that lifter 3b promotes clothing, is that the downside (downside of outer bung 2d) of washing and dewatering bucket 3 gets final product.As shown in Figure 9; Below nozzle is arranged on, even because wind speed is also to make quality better about 60m/s, therefore; Compare with the superincumbent occasion of nozzle, have the pressure that can reduce blowing unit 28 and the advantage of flow (can reduce the revolution of blast fan).And if nozzle below, then the blow-off direction of wind and gravity is in the opposite direction.Because when wind is to clothing, clothing is difficult to escape because of the deadweight of clothing, and the power F that acts on the clothing is unattenuated, therefore, has and can further make the second best in quality advantage.
In the occasion that nozzle 32d is located at downside, the downside that dry channel 29 and blowing unit 28 is located at outer bucket 2 more can installed the compactness that becomes.But,, therefore need make the countermeasure of blowing unit etc. of the water proof type of the immersion mechanism that anti-sealing is set because the washings in when washing get into and flow in the blowing unit 28 from nozzle 32d.
In this embodiment,, therefore, do not worry that washings immerse owing to the right oblique upper position that nozzle 32d is located at outer bung 2d.In this occasion, be necessary suitably to control the revolution of washing and dewatering bucket 3, clothing is promoted near the nozzle 32d, and wind is at a high speed directly blown on the clothing.Clothing is through being promoted to the top by the caused centrifugal force of the rotation of washing and dewatering bucket 3 and lifter 3b.Therefore, revolution has optimum value according to the diameter of washing and dewatering bucket 3, and the big more revolution of diameter is low more.But the clothing that falls fast because of gravity is also arranged,, therefore, be necessary the wind speed of that kind raising jet expansion as shown in Figure 8 owing to can't avoid the average nozzle and the distance of clothing to become also longer than the occasion that nozzle is arranged on downside.
Here, specify blowing unit 28.Figure 15 is the cutaway view of blowing unit 28.Figure 16 is a vertical view of having placed the state of impeller with the state of having dismantled the main fan cover.Figure 17 is a vertical view of having removed the state of fan cover.Figure 18 is the cutaway view of inlet outlet that is used for being convenient to understanding the blade 101c of impeller 101.Figure 19 is the cutaway view of impeller.Figure 20 is the vertical view of impeller.Figure 21 has removed the vertical view behind the side plate.

Inner space being formed by main fan cover 28d and fan cover 28c is formed with Vorticose runner.This Vorticose runner is a vortex tube 106, while play a part mobile deceleration of discharging from impeller 101 reclaimed as static pressure.Outlet at vortex tube 106 has the mouth of pipe 107, is provided with mouth of pipe 107a in fan cover 28c one side, is provided with mouth of pipe 107c, otch 107d, mouth of pipe 107e in main fan cover 28d one side.Be provided with heater 31 in the downstream of the mouth of pipe 107, be provided with outlet 115 in its downstream.
Air in the explanation blowing unit 28 flows below.If motor 28a rotates then impeller 101 rotations, thereupon, air is such shown in arrow 117 to be flowed into to impeller 101 from horn mouth 33a through filter passage 27 and the air-breathing runner 33b in air intake passage 33.Shown in arrow 116; High-speed air in that impeller 101 is boosted is assembled from the whole periphery discharge (arrow 118) of impeller and at vortex tube 106; Meanwhile slowed down; And such gap flow further downstream from the mouth of pipe 107 and motor 28a shown in arrow 119 is discharged from blowing unit 28 through outlet 115 by heater 31 heating backs.
The external diameter of impeller 101 is 140mm, and it is rotated with 16000r/min, and the peripheral speed of impeller 101 is about 117m/s under this condition, is about 200W as the output of blowing unit.Rise in order to obtain this bigger output and pressure, need guarantee intensity, thereby do impeller 101 with aluminum especially with metal.Because the thermal conductivity of aluminium is good, therefore, accepts by impeller 101 by means of rotating shaft 102 in the heat that motor 28a is produced, and to air, emit from impeller 101.Through in cooling motor 28a, the used heat of motor 28a is supplied with to air thus, thereby the air humidity that also can be used for need not improving drying system just improves temperature.
In addition, blade 101c is thin also can to guarantee intensity even if make, even if thereby increase blade sheet number and also can widely choose runner, therefore, can reduce the flowage friction resistance in the impeller 101.
Have again,, thereby can on side plate 101a, make bend 101g and the 101f of annulus portion owing to aluminium stretches easily; Therefore, can make parallel with the annulus portion of horn mouth 33a, in addition; Can strengthen the distance with horn mouth 33a, thereby can make the influence that is not subject to the leakage current that the gap through two annulus portions flows into, thereby turbulent flow is difficult for getting between the blade; Can make noise less, and can reduce fluid resistance.In addition, be 2mm though get the gap of two annulus portions, also can make this gap length for certain, therefore, can obtain at impeller when fan guard 28b moves, the amount of leakage current is difficult for changing this effect.
Because outlet otch triangularity with the blade 101c of impeller 101; Therefore can stagger and come from the mobile opportunity that flows into the mouth of pipe 107 of impeller 101; The mobile opportunity that flows into the mouth of pipe 107 that the speed from impeller 101 of can staggering periodically changes; Therefore, can reduce with the blade of impeller and revolution long-pending be that the noise of its integer multiple frequency of basic value is so-called blade sound.In addition, if be provided with triangular incision then in assembling during impeller 101, finding out easily has otch one side to should be the outside, thereby makes assembling easily.Here, though make leg-of-mutton otch, also can be oblique tilt.
Here used vortex tube 106 its angles of flare are 4 degree, in size if there is surplus then also can use the bigger angle of flare.The mouth of pipe 107 its fore-ends form linearity, and the distance between this front end and the impeller 101 is about 15mm, thereby reduce the increase of blade sound.For the increase that suppresses the blade sound otch 107d is set, thereby can ventilates.Utilize this otch 107d can alleviate the pressure oscillation that produces at the mouth of pipe 107, the inhibition effect of blade sound is bigger.Kerf width is 3mm in this embodiment, and the degree of depth is 5mm.Though strengthen the width of otch or strengthen the degree of depth then the inhibition effect of blade sound become big, and the unfavorable situation of pressure rising value step-down and so on also appears.In addition, because the major part of this otch 107d all is positioned at the position of the side plate 101a that does not touch impeller 101, therefore, the pressure rising value reduces hardly, and the inhibition effect of blade sound is bigger.
In addition; If use turbofan, then compare with Sirocco fan, can make more low speed of the air-flow of discharging from impeller 101; Even if little vortex tube (vortex tube that the angle of flare is little) amount of deceleration is also less; Thereby can reduce loss, therefore, even if having the characteristic that also can improve performance in the scrubbing-and-drying unit that does not spatially have surplus and can't choose vortex tube significantly than the highland.In addition, owing to also can make the width of impeller less, therefore, can realize save spaceization.In addition, fluid is flowed, thereby be difficult for forming the air trapping place that causes by fluid separation etc., therefore, have and to prevent that fleeces is detained and attached to the advantage on the blade 101c.
In addition, fan discharge to be pressed and air quantity in order to satisfy, and preferably with the revolution of 10000～20000r/min as impeller, the external diameter of impeller is made as 120mm～180mm degree.
Fig. 6 is the block diagram of the control device 38 of scrubbing-and-drying unit.The 50th, microcomputer, be connected each switch 12,13, the last action button input circuit 51 of 13a is connected with level sensor 34, temperature sensor 52, receives user's push-botton operation and washing procedure, the various information signals in the drying process.Output from microcomputer 50 is connected with drive circuit 54, and is connected with water-suppling electromagnetic valve 16, draining valve 25, motor 4, blowing unit 28, heater 31 etc., controls their switch and rotation, energising.And, be connected with light emitting diode 56, buzzer 57 with seven sections light emitting diode indicators 14 that are used for to the operating state of user notification washing machine.
Above-mentioned microcomputer 50 begins starting during energized at pushing power switch 39, carries out the basic control handling procedure of washing shown in figure 14 and drying.
Step S101
Carry out the state confirmation and the initial setting of scrubbing-and-drying unit.
Step S102
Light the display 14 of guidance panel 6, according to setting the washing/drying process from the indication input of pushbutton switch 13.Under the state of not indication input, the washing/drying process that the washing/drying process of automatic setting standard or last time implement.For example, imported the occasion of pushbutton switch 13a, set dry high-quality process in indication.
Step S103
Supervision is from the indication input and the branch process of the beginning switch 12 of guidance panel 6.
Step S104
Wash.Washing is washed successively, middle dehydration, rinsing, final dewatering, and is identical with general drum-type washing drying machine, so detailed.
Step S105
Confirm whether configure washing dry run and branch process.In the occasion of only setting washing process, finish running.
Step S106
In the occasion of setting the washing dry run, carry out warm wind dehydration.Temperature wind dehydration is with the low speed rotation blowing unit 28 that turns round, and to heater 31 energisings (strong mode) thus and make warm wind be blown into the temperature that improve clothings in the washing and dewatering bucket 3.Simultaneously, make washing and dewatering bucket 3 at a high speed rotation and from the clothing of heating slough effectively moisture (since temperature when rising the viscosity of water descend therefore can effectively dewater).In this embodiment example, the revolution of blowing unit 28 is set at per minute 11000 to be changeed.Its reason is, in order to prevent to surpass allowable current value (15A).
Step S107
Carry out dry operating 1.Blowing unit 28 low speed rotation, heater 31 carries out the positive and negative rotation of washing and dewatering bucket 3 repeatedly with strong mode running, in the position of the clothing in transposing washing and dewatering bucket 3, with the warm wind of high temperature to clothing.The all temperature of clothing rises and from the clothing transpiring moisture.
Step S108
Confirm whether to configure high-quality process and branch process.The occasion of the process beyond the high-quality process is carried out step S107 and is finished until drying.
Step S109
Whether affirmation reaches official hour and branch process from the elapsed time that drying begins.The aridity (quality of the quality of=dried cloth/wet cloth) that official hour is set in clothing did not reach before 0.9 as yet.
Drying is carried out as follows.At the dry initial stage, between the warming up period that the temperature that makes clothing rises, in order to make the temperature fast rise of clothing, it is important to give clothing with as much as possible heat.Between warming up period, few from the evaporation of the moisture of clothing.
Along with the temperature of clothing rises, become many from the evaporation of the moisture of clothing, therefore because heat of gasification makes the temperature of clothing rise latens, heating soon reaches balance with heat of gasification, the temperature of clothing become roughly necessarily (constant rate of drying).Heat of gasification reduces if the amount of moisture of clothing tails off then, and the temperature of clothing begins to rise once more, finishes drying (falling rate of drying) if the moisture of clothing disappears then to become with the roughly the same temperature of warm wind.The temperature of clothing began to rise when aridity reached near 0.9.
When clothing comprises a lot of moisture, though on clothing, rise fold also can flatten simply (from the spraying of the clothing of fold or with steam give moisture then fold disappear also can know).But, rise under the state of fold drying proceed to aridity be more than 9.0 then fold be immobilized.With the fold of immobilization one time after operation in eliminate and almost be unable to handle.Therefore, before aridity becomes 0.9, flatten fold and become important.
When actual drying, the dry material clothing different with thickness simultaneously is so aridity becomes time of 0.9 also according to clothing and difference.Therefore, in this embodiment example, be set in the time that the aridity of thin cotton dress thing that plays fold the most easily becomes 0.8 to 0.85 degree.And, owing to reach 0.9 asynchronism(-nization), therefore be necessary certainly to come setting-up time according to the cloth amount according to cloth amount aridity.
Step S110
Carry out dry operating 2.Under the situation that the positive and negative rotation that makes washing and dewatering bucket 3 is still proceeded, make blowing unit 28 rotation at a high speed, and after heater 31 is set at weak pattern, blow wind at a high speed on the clothing washing and dewatering bucket 3 in, in the flattening fold, carry out drying.When rotating blowing unit 28 at a high speed, heater 31 being set at weak pattern, is in order to prevent to surpass the allowable current value.In this embodiment example, the revolution of blowing unit 28 is set at per minute 16000 to be changeed.The input current of the blowing unit 28 when per minute 16000 changes is about 7A, and heater 31 is about 6A, and motor 4 is about 1A with control device 38.
In this step,, therefore descend than step S107 because heater 31 becomes weak pattern.Especially if aridity surpasses the temperature of 0.9 clothing to rise, move closer to warm wind-warm syndrome degree, but because warm wind-warm syndrome degree is low, therefore can the temperature of clothing be suppressed to lowlyer, also have the advantage that can alleviate the damage of clothing.
Dry when utilizing temperature sensor monitors temperature wind and cooling water temperature at discharging condensate, carry out, when the ratio of variations in temperature reaches the value of regulation, finish.
In addition, the also dry operating 1 of implementation step S107 not, and from just carrying out at first the dry operating 2 of step S110.Along with the cloth quantitative change is many, the transposing of the inboard in the washing and dewatering bucket 3 and the clothing of front face side is difficult to carry out the clothing rapid draing of the front face side that warm wind blew to.Therefore, through from rotating blowing unit 28 with high speed at first,, also can prevent on quick-drying clothing, to play fold even rate of drying has than great fluctuation process.
More than, according to the above embodiments, owing in dry operating, clothing is directly blown wind at a high speed, thereby utilize wind to open clothing, the fold of clothing is flattened, thereby can realize the dry mass that fold is few.
In addition, being arranged on the occasion of the upside of swing roller at the nozzle of the wind that will blow out above-mentioned high speed, is that about 1.5 cubic metres of per minute, wind speed are 90 meters to 130 meters of each seconds through making air quantity, can flatten the fold of clothing effectively.
In addition, be arranged on the occasion of the downside of swing roller at the nozzle of the wind that will blow out above-mentioned high speed, through make air quantity be approximately 1.5 cubic metres of per minutes, wind speed is 60 meters to 100 meters of each seconds, can flatten the fold of clothing effectively.Through following lateral blowing,, thereby promptly use lower wind speed also can flatten fold fully because of the clothing deadweight of falling increases the power to the clothing effect from clothing.Have again, owing to, make clothing as parachute, launch from the following lateral blowing of the clothing that falls, thereby the further effect of increasing flattening fold.
In addition, owing to use impeller as the part of blowing unit, and will possess front panel and rear board with suction inlet; Have blade between plate and the rear board in front, blade is made with metal along with sidle the impeller that moves back to a rear flank opposite with direction of rotation to outside diameter from the center, therefore; Can cause wind at a high speed; And can realize with less space, in addition, can reduce noise.
