Wind pushing mechanism 28 comprises motor 28a, blast fan (not shown), the fan guard 28b that drives usefulness.Built-in heater 31 on fan guard 28b, the air that heating is sent here from blast fan.The outlet of wind pushing mechanism 28 is connected with warm wind passage 30.Temperature wind passage 30 exports 32 by pleated tube A30a, the pleated tube joint 30b of rubber system with warm wind on being located at outer bung 2d and is connected.In the present embodiment, because wind pushing mechanism 28 is located at the upper right in the cabinet 1, has shortened to the distance of warm wind outlet 32 as far as possible the position that therefore warm wind outlet 32 right bank that are located at outer bung 2d make progress.
On the air entry of water discharge outlet 2b, wind pushing mechanism 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 wind pushing mechanism 28 of wind at a high speed and this wind directly blown warm wind outlet 32 on clothing.For the required performance of wind pushing mechanism, in the back narration.Use Fig. 6, Fig. 7 that the detailed content of warm wind outlet 32 is described.Fig. 6 is the front view that warm wind outlet 32 is provided with the outer bung 2d of portion, and Fig. 7 is the cutaway view that cuts off the warm wind outlet 32 of expression at the double dot dash line A-A place of Fig. 6.
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, with prevent washing and dewatering bucket 3 with outside enter clothing in the gap of bung 2d.Therefore, the 32a of export department of warm wind outlet 32 is formed in the inner part highlightedly at the inner peripheral surface of the 2c of ratio open portion, nozzle 32d is to washing and dewatering bucket 3 inner openings.By like this, directly blow to clothing in the washing and dewatering bucket 3 from the warm wind of nozzle 32d ejection on.
And 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, nozzle is made flat kerf reduce overhang, and the surface configuration of peristome 2c and the 32a of export department changes smoothly.In addition, utilize air-supply cover 34 formation stream 32c, thus and stream 32b between do not have the variation of useless 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.And, cover 34 installed surfaces by blowing and be located on the direction opposite, thereby can prevent to wash and the quilt of the end of a thread when dry etc. is hung with the peristome 2c of outer cover 2d, and, need not to decompose main body and cover 34, therefore become the structure that keeps in repair easily with regard to dismantling air-supply.
Wind during dry operating mobile as follows.If running wind pushing mechanism 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, how wet air contacts and the dehumidifying that is cooled with cooling water high temperature, becomes dry Cryogenic air and enters filter passage 27 (arrow 43).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 wind pushing mechanism 28 (arrow 44).And, heat once more with heater 31, be blown in the washing and dewatering bucket 3 and circulate.In the meantime, make washing and dewatering bucket 3 with the positive and negative rotation of low speed, with clothing be promoted to nozzle 32d near, warm wind is at a high speed directly blown on the clothing.
Fig. 8 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 rotating speed of change motor 28a and the area of nozzle 32d.In addition, wind speed is the value that the result according to the air quantity pressure characteristic of having measured wind pushing mechanism 28 calculates.The air quantity pressure characteristic is measured with device shown in Figure 13.On the outlet of the air entry of surge tank and wind pushing mechanism 28, throttle orifice is installed, when the rotating speed to the diameter of throttle orifice and motor 28a carries out various changes, measure air quantity and the air entry of wind pushing mechanism 28 and the pressure of outlet, obtained the air quantity pressure characteristic.And, measure the air entry of the wind pushing mechanism 28 when being installed in wind pushing mechanism 28 on the scrubbing-and-drying unit and the pressure of outlet, obtain air quantity according to above-mentioned air quantity pressure characteristic, the value that this air quantity is removed with nozzle area is as wind speed.
Experiment condition as shown in FIG., testing machine is the drum-type washing drying machine with washing and dewatering bucket of diameter 600mm and volume 75L, the cloth amount is 2kg.The evaluation of quality is carried out with various clothings, but has represented the most tangible thin cotton pyjama result of a fold.Evaluation is the sense evaluation according to the 5 visual stages, will represent with Figure 14 the example of the quality condition of sense evaluation of estimate.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 a reference, the quality condition that does not carry out drying after will washing and directly hang the occasion of drying is represented with Figure 15.(a) being the situation of dehydration back convection drying, (b) is to carry out dry situation after flattening the dehydration fold gently.(a) be to be with dehydration fold drying, the sense evaluation of estimate is about 4, (b) is but that the dehydration fold has reduced also residual a lot of shallow fold, and the sense evaluation of estimate is about 4.5.
As we know from the figure, (A), wind speed improves along with uprising quality.But also find for the wind speed quality saturated, if the tendency of the too high then opposite deterioration of wind speed.And air quantity is many more, the wind speed step-down that quality is saturated.Air quantity 0.8m 3The occasion wind speed of/min is about 140m/s and the sense evaluation of estimate is about 3, air quantity 1.0m 3Wind speed is about 130m/s and the sense evaluation of estimate is about 3.3, air quantity 1.3m during/min 3Wind speed is about 120m/s and the sense evaluation of estimate is about 3.9, air quantity 1.5m during/min 3Wind speed is about 110m/s and the sense evaluation of estimate is about 4.0, air quantity 1.7m during/min 3Wind speed is about 100m/s and the sense evaluation of estimate is about 4.2 during/min, even increase wind speed more than this, quality also improves hardly.And, be 1.5m at air quantity 3Obtained the quality equal when/min is above with fesloon drying.
(B) as if the side's better quality how of the identical then air quantity of wind speed, but air quantity is from 1.5m 3/ min rises to 1.7m 3The improvement degree of the quality during/min reduces.Hence one can see that, even air quantity is increased to more than the needs, can not expect the improvement of quality.
Like this, the big more quality of wind speed, air quantity is good more.Air quantity and wind speed are not which side strengthens wherein, and consider that preferably both balances set.Specifically, need not merely consider quality, also to consider current value (occasion of home-use 100V source power supply, wind pushing mechanism 28 and heater 31, motor 4, control device 38 to add up to 15A following) and drying property, make the passage that wind circulates flow path area, decide wind speed and air quantity to the installation of scrubbing-and-drying unit etc.
If the sense evaluation of estimate is more than 3, even then also can finish simply, if the sense evaluation of estimate is more than 4, even it is discontented also few then directly to wear dried clothing in the occasion of the after-applied ironing of drying.
In order to make the sense evaluation of estimate is more than 3, air quantity 0.8m 3Wind speed is about more than the 140m/s during/min, air quantity 1.0m 3Wind speed is about more than the 110m/s during/min, air quantity 1.3m 3Wind speed is about more than the 92m/s during/min, air quantity 1.5m 3Wind speed is about more than the 75m/s during/min, air quantity 1.7m 3Wind speed is about more than the 70m/s during/min, the minimum 0.8m that also needs 3The air quantity of/min.In addition, air quantity has a significant impact drying property, but I haven't seen you for ages prolongs drying time because air quantity is crossed, and therefore considers that from the viewpoint of drying property air quantity also needs 0.8m 3More than/the min.
Be not easy the occasion of the clothing of fold, also can have obtained the quality of sense evaluation of estimate more than 3 than above-mentioned low value, but generally be dry various clothings of while, the decision wind speed gets final product so merge with the clothes that plays fold easily.
Use Fig. 9 to illustrate that the wind by will be at a high speed reduces the reason of the fold of clothing to the clothing.Fig. 9 (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 clothings at the back side that is illustrated in clothing.If the collision of wind and clothing, then in power of doing on the clothing to extend (arrow (1)) and power (arrow (2)) to stretch along about the wind of clothing Surface runoff with clothing collision back change flow direction in order to wind.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 sail when aweather flow direction flattens such, also acts on 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 easily in the drying, is difficult to produce fold, so in the power of this consideration (1).
(1) power F, shown in Fig. 9 (b), if the air quantity of the wind that blows out from nozzle 32d be Q, when wind speed is V, amassing of available Q and V represented.And, the wind (jet flow) that blows out from nozzle 32d by with the effect of the viscosity of the bigger speed difference of ambient air and air, be involved in ambient air and enlarge mobile width, and this moment, jet flow flowed (still from downstream when reducing speed V, from the very little occasion of the distance X of nozzle 32d (central area of jet flow, the occasion of the round nozzle position from nozzle to about 6 times of nozzle diameters), speed V is roughly certain).
That is, along with the distance X from nozzle 32d increases, the power that the clothing of per unit area is subjected to (pressure that clothing is subjected to from wind) reduces.Thereby the closer to nozzle 32d, the effect that flattens fold is big more with clothing.
The result of Fig. 8 F that exerts oneself is rearranged, then become as shown in figure 10.And, in Fig. 8, air quantity Q is represented with volume flow, and (be 1.24kg/m 20 ℃ the time in this density that is multiplied by air 3) be converted to mass flow.As we know from the figure, increase the quality official and can evaluation of estimate rise with putting forth effort F, but be that 3.5N is roughly saturated when above at power F, the sense evaluation of estimate is about about 4.7.Though the sense evaluation of estimate has fluctuation a little, enter in the scope of dotted line of figure.Hence one can see that, is more than 3 in order to make the sense evaluation of estimate, and the F that exerts all one's strength gets final product more than being about 2.2N.
Figure 11 is the figure that has summed up the experimental result of cloth amount from 1kg to 4kg with Figure 10 equally.As we know from the figure, the cloth amount is many more, needs big more power F for obtaining identical sense evaluation of estimate.This be because, the amount of the clothing of the heterogeneous more volume to washing and dewatering bucket 3 of cloth amount increases, clothing is difficult to launch, therefore flattening fold needs bigger power.And, saturated in the above sense evaluation of estimate of a certain power, therefore according to the cloth amount, control air quantity, wind speed for acting on best power, thereby do not circulate useless wind, obtain best quality, can reduce consumption electric power.As the control method of air quantity, wind speed, the easiest is the method for rotating speed (the cloth amount increases and more improve rotating speed) of control wind pushing mechanism 28, but also can be the method that the area of change nozzle 32d comes control area.
Along with the cloth amount increases, the maximum of sense evaluation of estimate reduces, and the official can evaluation of estimate be about 4.8 when cloth amount 1kg, is about 4.7 during cloth amount 2kg, is about 4.2 during cloth amount 3kg, is about 3.5 during cloth amount 4kg, is about 2.6 during cloth amount 5kg.In this figure, for obtaining sense mean value required power F more than 3, when cloth amount 1kg, be about more than the 0.8N, be about during 3kg more than the 3.0N, be about more than the 3.4N during 4kg.In this experiment, when cloth amount 5kg, do not reach sense evaluation of estimate 3.From above content as can be known, even be relatively good more than the 0.8N at the few occasion of the cloth amount F that also will exert all one's strength.
Like this, according to the volume and the cloth amount of washing and dewatering bucket 3, be used to obtain the power difference of necessary quality.So, the volume of the washing and dewatering bucket 3 of every cloth amount is defined as volumetric ratio (volume of=washing and dewatering bucket 3/cloth amount).Then, the result so that amassing of power F and volumetric ratio put Figure 10 in order then obtains Figure 12.As we know from the figure, long-pending for power and volumetric ratio, quality official can evaluation of estimate enters in the scope of dotted line of figure.This figure comprises the index relevant with dry mass (volume of power F, washing and dewatering bucket 3, cloth amount), by using this figure, can derive the condition that is used to obtain aimed quality.
In order to make the sense evaluation of estimate is more than 3, gets final product more than power and volumetric ratio long-pending is made as about 62NL/kg.As an example, when volume 75L, the cloth amount 4kg of washing and dewatering bucket 3, obtain and be used to obtain the condition of sense evaluation of estimate more than 3.
Volumetric ratio=75/4=18.75L/kg, power F=62/18.75=3.31N.
Consider drying property then and air quantity is decided to be 1.65m 3/ min (=0.0341kg/s), then wind speed be about 97m/s (=3.31/0.0341).Therefore, in order to obtain this air quantity, wind speed, the area of nozzle 32d is set at 2.83 * 10 -4m 2(283mm 2) get final product.
In the present embodiment example, wind pushing mechanism 28 its blast fan diameters are that 140mm, impeller thickness are that 8.1mm and rotating speed are that per minute 15000 changes.The fan discharge pressure becomes about 7000Pa (air themperature 30 ℃ time) thus, obtains above-mentioned air quantity, wind speed.
As mentioned above, become well in order to make quality, increased force will F (increase air quantity Q or increase wind speed V), and the distance X that reduces nozzle and clothing get final product (making the close nozzle of clothing).
In order to increase air quantity Q, need the rotating speed of the fan of raising wind pushing mechanism 28, or increase the external diameter and the impeller 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 increase the pressure loss and reduce temperature of warm wind etc. with heater 31 evaporative cooling water owing to filter 8a is wetting, thereby cause the significantly reduction of drying efficiency, therefore must strengthen the flow path area of dry channel 29.Therefore, if increase considerably air quantity, then the size of passage and wind pushing mechanism becomes big, causes the change of size of cabinet 1 big, is difficult to the scrubbing-and-drying unit setting in the family.
On the other hand, in order to increase wind speed V, wind pushing mechanism 28 made pressure type and reduce nozzle area get final product.In the occasion of using general turbofan as wind pushing mechanism 28, existence is with low rotating speed and strengthen the method for diameter of blast fan and the diameter of blast fan is little and improve the method for rotating speed, and at a high speed rotation have can be installed in identical in the past cabinet on advantage.
From the experimental result of quality shown in Figure 8, find 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 clothing distortion.The reason of deterioration that therefore, Here it is.
In order to reduce the distance X of nozzle 32d and clothing, suitably control the rotating speed of washing and dewatering bucket 3, clothing is promoted near nozzle 32d, and wind is at a high speed directly blown on the clothing.Clothing draws and promotes upward by using by caused centrifugal force of the rotation of washing and dewatering bucket 3 and lifter 3b.Therefore, rotating speed has optimum value according to the diameter of washing and dewatering bucket 3, and the big more rotating speed of diameter is low more.In addition, lifter 3b height is relatively good.But if the height height of lifter 3b, then promoting the clothing that is immersed in the water needs high torque (HT), needs to use the motor 4 of high-output power, therefore needs to consider the power output of motor and the shape that determines lifter 3b.
In order further to shorten the distance X of nozzle 32d and clothing, near the place that must be by clothing when drying nozzle 32d is set and gets final product.That is, the position of nozzle 32d being arranged on the downside (downside of outer bung 2d) that promotes the washing and dewatering bucket 3 of clothing by lifter 3b gets final product.Figure 16 is the figure that appends the result of the situation below nozzle 32d is located in Figure 10.In order to obtain sense evaluation of estimate 3, power F is about 1.5N and gets final product, and just can obtain the quality of same degree in the power of last occasion about little 30% than nozzle.The long-pending value of power F shown in Figure 12 and volumetric ratio also can reduce 30%, is set at more than the 44NL/kg more than 3 and gets final product in order to obtain the sense evaluation of estimate.Like this, has the advantage that can reduce the pressure and the air quantity (can reduce the rotating speed of blast fan) of blowing unit 28 with nozzle 32d in last occasion comparison.And following, then the direction of the blow-off direction of wind and gravity is opposite as if nozzle 32d.When wind was to clothing, because the deadweight clothing of clothing is difficult to escape, the F that can exert all one's strength acted on the clothing effectively.
In the occasion that nozzle 32d is located at downside, the downside that dry channel 29 and wind pushing mechanism 28 are located at outer bucket 2 more can become compact installing, and can also reduce the pressure loss.But,, therefore need make the countermeasure of the wind pushing mechanism etc. of the waterproof type that enters anti-locking mechanism that water is set because the washings in when washing enter and flow in the wind pushing mechanism 28 from nozzle 32d.So wind pushing mechanism 28 and present embodiment example are located at the top of cabinet 1 equally, make with passage and the structure that the nozzle 32d that is located at downside is connected, and can prevent entering of washings thus.
Figure 17 is the block diagram of the control device 38 of scrubbing-and-drying unit.The 50th, microcomputer is connected with level sensor 340, temperature sensor 52 with action button input circuit 51 on being connected each switch 12,13,13a, carries out user's push-botton operation and receives various information signals in washing procedure, 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, wind pushing mechanism 28, heater 31 etc., controls their switch and rotation, energising.And, and be used for notifying seven sections light emitting diode indicators 14 of the operating state of washing machine to be connected with light emitting diode 56, buzzer 57 to the user.
Above-mentioned microcomputer 50 begins starting when connecting power supply at pushing power switch 39, carries out as shown in figure 18 washing and dry basic control handling procedure.
Step S101 carries out the state confirmation and the initial setting of scrubbing-and-drying unit.
Step S102 lights 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.
The indication input and the branch process from beginning switch 12 of step S103 supervisory work panel 6.
Step S104 washs.Washing is washed successively, middle dehydration, rinsing, final dewatering, and is identical with general drum-type washing drying machine, so detailed.
Step S105 confirms whether configure washing dry run and branch process.In the occasion of only setting washing process, finish running.
Step S106 carries out warm wind dehydration in the occasion that configures the washing dry run.Temperature wind dehydration is with low speed rotation running wind pushing mechanism 28, 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, be that per minute 11000 changes with the speed setting of wind pushing mechanism 28.This be because, in order to prevent to surpass allowable current value (15A).
Step S107 carries out dry operating 1.Wind pushing mechanism 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 confirms 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 confirms whether reach 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 at than clothing reaches 0.9 front.
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 rises the temperature of clothing latens, heating and heat of gasification reach balance soon, the temperature of clothing become roughly necessarily (constant-rate method 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 (lapse rate drying) if the moisture of clothing disappears then to become with the roughly the same temperature of warm wind.The moment that the temperature of clothing begins to rise is that aridity is when reaching 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 0.9 then fold be fixed.Fixing fold is once eliminated almost and can not be accomplished with operation afterwards.Therefore, before aridity becomes 0.9, flatten fold and become important.
When reality dry, 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 that is set at the thin cotton dress thing of the easiest fold becomes the time about 0.8 to 0.85.And, become 0.9 asynchronism(-nization) according to cloth amount aridity, therefore also need certainly to come setting-up time according to the cloth amount.
Step S110 carries out dry operating 2.The positive and negative rotation of washing and dewatering bucket 3 is proceeded, and with wind pushing mechanism 28 rotation at a high speed, heater 31 is set at the wind that blows high speed on weak pattern and the clothing in washing and dewatering bucket 3, carries out drying when flattening fold.When rotating wind pushing mechanism 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, be that per minute 16000 changes with the speed setting of wind pushing mechanism 28.The input current of the wind pushing mechanism 28 when per minute 16000 changes is about 7A, and heater 31 is about 6A, and motor 4 and control device 38 are about 1A.
In this step, because heater 31 becomes weak pattern, therefore relatively descend with step S107.Especially if aridity surpasses the temperature of 0.9 clothing to rise, move closer to warm wind-warm syndrome degree, but, therefore the temperature of clothing can be suppressed lower, also have the advantage that can alleviate the damage of clothing because warm wind-warm syndrome degree is low.
Dry when utilizing temperature sensor monitors temperature wind and cooling water temperature at discharging condensate, carry out, when the ratio of variations in temperature becomes 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, and blows to the clothing rapid draing of the front face side of warm wind.Therefore, by from rotating wind pushing mechanism 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.
