On the air entry of outlet 2b, blowing unit 28 and outlet, be provided with temperature sensor (not shown).

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, need to produce the blowing unit 28 of wind at a high speed and this wind directly blown warm wind outlet 32 on clothing.For the required performance of blowing unit, in the back narration.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 32 of expression with double dot dash line A-A at Fig. 7.

Temperature wind outlet 32 is provided with along peristome 2c from the front side of outer bung 2d, is formed with

stream

32b, 32c in inside.Inlet in warm wind outlet 32 is equipped with pleated tube joint 30b, is formed with nozzle 32d in the outlet of stream 32c.The internal diameter of the internal diameter of the peristome 2c of outer bung 2d and the peristome 3a of washing and dewatering bucket 3 is set at roughly the same, enters in the gap of washing and dewatering bucket 3 and outer bung 2d to prevent clothing.Therefore, the inner peripheral surface that the 32a of export department of warm wind outlet 32 is formed the 2c of ratio open portion is also outstanding in the inner part, and makes nozzle 32d to washing and dewatering bucket 3 inner openings.By like this, directly blow to clothing in the washing and dewatering bucket 3 from the Wen Fengke of nozzle 32d ejection on.

In addition, if the overhang of the 32a of export department is too much, the motion of the clothing when then hindering washing and drying therefore as shown in Figure 7, is made flat kerf with nozzle and is reduced overhang, and the surface configuration of peristome 2c and the 32a of export department is changed smoothly.In addition, stream 32b and stream 32c make the variation of no unnecessary projection and rapid flow direction, and reduce gradually to nozzle 32d flow path area.By like this, can reduce the pressure loss and the fluid sound that when at a high speed distinguished and admirable crosses stream 32b, 32c, produce.

Wind during dry operating mobile as follows.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, be drawn 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 enters filter passage 27 (arrow 43) by contact the dehumidifying that is cooled with cooling water.Remove the end of a thread by the gauze filter 8a that is located on the filter passage 27, and enter air intake passage 33, be 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 by 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, measured 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 as shown in FIG., testing machine is that to have diameter be that 600mm and volume are the drum-type washing drying machine of the washing and dewatering bucket of 75L, the cloth amount is 2kg.The evaluation of quality is carried out with various clothings, and that expression has been the most tangible thin cotton pyjama result of fold.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 is provided with nozzle 32d on above-mentioned position, 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 of estimators' a mean value.

As we know from the figure: (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, it is following that blowing unit 28 and heater 31, motor 4, control device 38 electricity consumptions amount to 15A) and drying property, wind are circulated flow path 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, in the occasion of top nozzle, be necessary that wind speed is more than the 90m/s when flow is 1.5m3/min, but owing to exist if the tendency of the too high then deterioration of wind speed, therefore, the highest also will being suppressed at about 130m/s of wind speed 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.Being used for producing the nozzle area of above-mentioned wind speed, is 190～280mm in the occasion of top nozzle ², be 310～415mm in the occasion of following nozzle ²Below.Therefore, the performance that on blowing unit 28, needs to make above-mentioned flow to be enough to flow through from the nozzle of above-mentioned area.In the present embodiment example, nozzle location is that top nozzle and nozzle area are 250mm ²(incision-like of width 50mm * 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 than above-mentioned wind speed, play the clothing of fold easily and determine wind speed to be advisable so cooperate.

Use Figure 12 to illustrate that the wind by 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 make open power (arrow (1)) on the clothing in order to wind and by changing flow direction with clothing collision back along the wind of clothing Surface runoff about the power (arrow (2)) of stretching.Flatten the fold of clothing with the power of this (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), if the flow of the wind that will blow out from nozzle 32d is made as Q, wind speed is made as V, long-pending proportional with Q and V then.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 little 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 illustrate 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 or heater 31, then, therefore must strengthen the flow path 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 improve revolution under the little situation of the diameter that still keeps blast fan 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 experimental result of quality shown in Figure 9, found if the phenomenon of the too high then deterioration of wind speed.This can not illustrate with foregoing.If the motion of the clothing in the observation experiment is as can be known if wind speed is too high then because the impetus of wind produces the phenomenon of twisting as 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, be 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 direction of the blow-off direction of wind and gravity is opposite.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 are located at outer bucket 2 more can become compact installing.But,, therefore need make the countermeasure of blowing unit etc. of the water proof type of the anti-locking mechanism of immersion that water is set because the washings in when washing enter and flow in the blowing unit 28 from nozzle 32d.

In the present embodiment example,, 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 by being promoted upward 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 hurtles down because of gravity is also arranged,, therefore, be necessary to improve as shown in Figure 8 the wind speed of jet expansion owing to can't avoid the average distance of nozzle and clothing to become also longer than the occasion that nozzle is arranged on downside.

Here, describe blowing unit 28 in detail.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.

Blowing unit 28 comprises: motor 28a; And comprise the main fan cover 28d of impeller 101 and the fan guard 28b that fan cover 28e constitutes by inside.Be provided with on fan cover 28e in central authorities and have the horn mouth 33a that circular open and section comprise part with curvature and circular part, the 101f of annulus portion and the circular of horn mouth 33a that constitute impeller 101 are overlapped.At this moment, the circular part of horn mouth 33a enters the inboard.

Impeller 101 comprises: be fixed on mainboard (being rear board in claims) 101b on the rotating shaft 102 of motor 28a; Blade 101c; And side plate (being front panel in claims) 101a that has opening in central authorities with suction inlet.Mainboard 101b is sandwiched by stiffener 101d and stiffener 101e, is fixed by caulking part 111a and caulking part 111b.This caulking part 111a and caulking part 111b pass through also to fix by riveted joint from blade one side and the side reinforcing opposite with blade every one.On side plate 101a, be provided with bend 101g that bend into to the direction opposite with the part of mainboard 101b almost parallel and its central portion and the 101f of annulus portion that forms suction inlet with mainboard 101b.

Blade 101c makes the shape of moving back to external diameter one rear flank gradually from internal diameter one side with respect to the direction of rotation 109 of impeller 101.This blade generally is also referred to as backward inclined blade, has used the fan of the impeller with this blade shape to be also referred to as turbofan.Blade with the shape of advancing to direction of rotation is called the forward direction blade, has used the fan of the impeller with this blade shape to be also referred to as Sirocco fan or multi blade fan.

On blade 101c, be respectively equipped with 5 projections (not shown), these projections be inserted in each 5 slot (not shown) corresponding that are arranged on side plate 101a and the mainboard 101b with blade in its both sides, afterburning and do flat projection and fix from both sides.As this method, while carry out then can making the height when riveting less if apply ultrasonic wave.Blade 101c is 8 in this embodiment, these all is positioned at rivets operation after mainboard 101b and side plate 101a go up.Make in the caulking part caulking part 110a of close internal diameter not touch the bend 101g of side plate 101a.In addition, make the front end of blade 101c also not touch the bend of side plate 101a.

In impeller 101, side plate 101a and mainboard 101b and blade 101c are metallic articles, use aluminium especially.In this occasion, use in aluminium the also the highest superduralumin of intensity.Stiffener 101d and stiffener 101e are ironworks, use uncorruptible stainless steel in this occasion.Two stiffener 101d use the different plate of its external diameter with 101e, can relax stress thus and concentrate when having applied various external force.

Be formed with circinate stream in the inner space that forms by main fan cover 28d and fan cover 28c.This circinate stream is an eddy duct 106, while play a part mobile deceleration of discharging from impeller 101 reclaimed as static pressure.Outlet at eddy duct 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 downstream, be provided with outlet 115 in its downstream as the mouth of pipe 107 of dividing plate.

Main fan cover 28d and motor 28a part in the central get involved vibration-proof rubber 105 and support, though not shown, between the motor engineering plastics 28b of motor 28a and main fan cover, also get involved four vibration-proof rubbers and support.In addition, make vibration-proof rubber 105 have both tight function in case air flows out from main fan cover 28d.

The following describes flowing of air in the blowing unit 28.If motor 28a rotates then impeller 101 rotations, thereupon, air flows into to impeller 101 from horn mouth 33a by filter passage 27 and the air-breathing stream 33b in air intake passage 33 shown in arrow 117 like that.Shown in arrow 116, assemble from the whole periphery discharge (arrow 118) of impeller and at eddy duct 106 at the high-speed air that impeller 101 is boosted, meanwhile be decelerated, and shown in arrow 119,, heated the back by heater 31 and discharged from blowing unit 28 by outlet 115 like that from the gap flow further downstream of the mouth of pipe 107 and motor 28a.

The external diameter of impeller 101 is 140mm, 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 so big 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.By 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 stream between the blade, therefore, can reduce the flowage friction resistance in the impeller 101.

Have again, because aluminium stretches easily, thereby can on side plate 101a, make bend 101g and the 101f of annulus portion, 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 by two annulus portions flows into, thereby turbulent flow is difficult for entering 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.

Air intake passage 33 inserts left side from dry channel 29 leaked-in airs from Figure 15, therefore exists on the flowing when arriving horn mouth 33a and departs from.Because the front end of the blade 101c of impeller 101 is positioned at the rear side of bend 101g, therefore, is not subject to the mobile influence of bias current, prevents the increase of fluid resistance, and can suppress the generation by the caused noise of movement disorder, thereby can reduce noise.

Have again, can make from the leakage current between horn mouth 33a and the side plate 101a and after being attached to wall, flow into blade 101c, thereby also can obtain to suppress this effect of increase of the fluid resistance that produces by turbulent flow.In addition, blade 101c is contacted with side plate 101a planely, thereby between blade 101c and side plate 101a, be difficult for forming the gap, thereby the performance that also can obtain being difficult for causing being produced by leakage current reduces 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.

In addition, to make its effect of shape of giving prominence to even if replace triangular incision also almost constant triangular in shapely, and can do and make the corresponding more merit of outstanding shape under identical revolution, thereby also can obtain making air quantity and the bigger this effect of pressure.In addition, even if being done saw-toothed shape, outlet also can obtain same effect.Like this, be different from entrance side, can obtain effect as described so far by the outlet shape that makes blade.

Here used eddy duct 106 its angles of flare are 4 degree, in size if there is surplus then also can use the bigger angle of flare.Yet because the size of blowing unit is limited, thereby can't make eddy duct become big, therefore, make eddy duct curling starting point and impeller between distance be 9mm, form circinate wall, from the position of the starting point of curling along forming the wall of linearity in the opposite direction with whirlpool side, form with the mouth of pipe 107 and link to each other, make the distance between its front end and the impeller 101 be about 15mm, thus than eddy duct wall with the minimum curling initial point position of the distance of impeller, bigger than the distance of mouth of pipe front end and impeller.Thus, suppress the increase of blade sound energetically.If strengthen the distance from impeller of mouth of pipe front position, then further reduce the blade sound, and on performance, have the tendency that efficient begins to reduce.

In addition, begin the continuous roughly wall of linearity of one side from the whirlpool destination node, and from this destination node, the angle when having observed the mouth of pipe is the angle of the starting point of curling, and uses 60 to spend to 70 degree degree usually, and is about the little of 45 degree in the present embodiment towards the downstream.This is that the starting point angle " Invest, Then Investigate " fluid property that curls is somebody's turn to do in the rotation of property ground by experiment, and judges near the angle that determines after the efficient higher position this angle.The velocity flow profile at position that straight line is linked the front end of the destination node of whirlpool and the mouth of pipe is investigated, and measurement result is roughly even flow distribution.Drying system, owing to be passage is connected circulation with cylinder system, and, sharply enlarge in the downstream flow path of the mouth of pipe, thereby think that the angle of this curling starting point suits.

The downstream of this mouth of pipe 107 sharply increases towards heater 31 areas.At the back side of the mouth of pipe, open along the above-below direction expansion of Figure 16, and also expand out at the above-below direction of Figure 17.If so rapid increase area then flows and can only be a significant slowdown and separate.Particularly, so rapid area increases and causes the separation fully of flowing, and becomes bigger fluid resistance, and therefore, to fan, pressure rises and reduces greatly.As shown in figure 17, in the present embodiment, main fan cover 28d one side constitutes in the downstream of nozzle position and roughly is the plane, and fan cover 28e one side is bent into gradually towards heater 31, and flows to the front of heater 31.

Like this, by with the distance between main fan cover 28d and the fan cover 28e, in other words, the axial distance of motor 28a (or impeller) is not that linearity ground strengthens, but along with strengthening rate of change downstream gradually from the mouth of pipe, thereby make the rate of deceleration at the bigger position of speed little, and drop to the position abrupt deceleration of a certain degree in speed.By like this, suppress mobile separation at the deceleration start-up portion, rejection reduces, and makes flowing velocity diminish, and the position less at the kinetic energy that flows is a significant slowdown.Therefore, suppress the increase of flow resistance energetically.In addition, owing to can improve the uniformity of the flowing velocity when entering heater, therefore, can prevent the heating of heater.

In addition because by this separated region being narrowed down eliminate the bad influence of flowing to upstream side, therefore, suppress the blade sound aspect also can obtain effect.In addition, form planar section when changing,, can make curved surface structure, therefore, also can obtain to improve this effect of intensity this on linearity ground.

Have again, 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, therefore, the inhibition effect of blade sound is bigger.Kerf width is 3mm in this embodiment, and the degree of depth is 5mm.Though the width of increasing otch or the increasing 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 occurs.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, from flowing not directly by otch 107d that impeller 101 flows out, therefore, the pressure rising value reduces hardly, and the inhibition effect of blade sound is bigger.

In addition, otch is not limited to one, also can be more than two, though what reduce the pressure rising value, also can strengthen the reduction amount of blade sound.

The axial distance Hs of eddy duct 106 is also inequality for the curl direction of eddy duct, and this distance becomes big gradually from the curling starting point of whirlpool.It is not the external peripheral zone of impeller that this axial distance becomes big part, and becoming big is axial distance till the outer thoughtful part that enters to the inside of impeller.In this embodiment, axial distance Hs changes to the recess of the part that is positioned at horn mouth 33a.For making axial distance Hs gradually big, the face of fan cover 28e side is made on-plane surface.Thus, along with the accumulation in a circumferential direction of flowing of flowing out from impeller makes institute's air flowing flow become big, the area that is flow through enlarges than increasing also with the angle of flare, thereby promotes the deceleration that air flows.In addition, forming highly inconsistent part in a circumferential direction, is advisable with the curling starting point of whirlpool in this position.Especially, if be arranged on the position of the starting point of curling, then the blade sound reduces.By making this axial distance Hs gradually big, improve about 2% as efficient.In addition, can not bring especially bad influence to blade sound etc.

In addition, the distance from the axle center of the scope that axial distance Hs is changed is made littler than the external diameter of impeller, and under making than the big situation of the external diameter of impeller, fails to obtain efficient and improve.

In addition, if use turbofan, then compare with Sirocco fan, can make the more low speed that flows of discharging from impeller 101, even if little eddy duct (eddy duct that the angle of flare is little) amount of deceleration is also less, thereby can reduce loss, therefore, even if having the feature that also can improve performance in the scrubbing-and-drying unit that does not spatially have surplus and can't choose eddy duct 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, also 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, is 120mm～180mm degree with the external diameter of impeller.

Fig. 6 is the block diagram of the control device 38 of scrubbing-and-drying unit.The 50th, microcomputer is connected with level sensor 34, temperature sensor 52 with action button input circuit 51 on being connected each

switch

12,13,13a, receives the various information signals in user's push-botton operation and washing procedure, the drying process.Be connected with drive circuit 54 from the output of microcomputer 50, and be connected, control their switch and rotation, energising with water-suppling electromagnetic valve 16, draining valve 25, motor 4, blowing unit 28, heater 31 etc.In addition, 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 when connecting power supply at pushing power switch 39, carries out as shown in figure 14 washing and dry basic control handling procedure.

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 the present 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.

Dry following carrying out.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 and heat of gasification reach balance soon, 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, under the state of fold that remained unchanged 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 the present embodiment example, the aridity of thin cotton dress thing that is set in the easiest fold becomes the time of 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 the present 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, is about 1A with motor 4 and control device 38.

In this step, because heater 31 becomes weak pattern, therefore descend than step S107.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 the temperature of clothing can 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, by from rotating blowing unit 28 with high speed at first,, also can prevent from 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 brace to open clothing, the fold of clothing flattens, 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 by 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, by 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.By the following lateral blowing from clothing, because of the clothing deadweight of falling increases power to the clothing effect, thereby promptly the lower wind speed of use also can flatten fold fully.Have again, owing to, make clothing as parachute, launch, thereby further strengthen the effect that flattens fold from the following lateral blowing of the clothing that falls.

In addition, because the part as blowing unit is used impeller, possess front panel and rear board with suction inlet, has blade between plate and the rear board in front, owing to make blade along with sidle the impeller that moves back to a rear flank opposite to outside diameter from the center, therefore with direction of rotation with metal, can cause wind at a high speed, and can realize with less space, in addition, can reduce noise.
