In addition, there is the swing roller of accommodating laundry, drive the motor of this swing roller, and the cabinet that supports above-mentioned swing roller, and carry out in the drying machine or scrubbing-and-drying unit of dry operating, be arranged on the mechanism of in above-mentioned dry operating, the clothing being contained in above-mentioned swing roller directly being dried, the mechanism of blowing this wind comprises wind pushing mechanism and the nozzle that is located at the discharge side of this wind pushing mechanism, this nozzle is arranged on to the downside of above-mentioned swing roller, and be configured to the air quantity (units/kg/s) of the wind blowing out from said nozzle and wind speed (m/s of unit) long-pending and be multiplied by swing roller volume (unit liter) and be more than 44 by the value of quality (units/kg) removal of clothing.
Also have, air quantity is 0.8m
3more than/min (0.0165kg/s).
The present invention has following effect.
The drying machine forming like this, owing to clothing directly being blown to wind at a high speed in dry operating, therefore extends clothing by wind, and the fold of clothing flattens, and can realize the dry mass that fold is few.And, because above-mentioned wind has the long-pending wind speed arranging according to above-mentioned air quantity of air quantity of regulation, so considered the relation that fold is flattened to effective air quantity and wind speed.
And, the nozzle that blows out the wind of above-mentioned high speed is being located to the occasion of the upside of swing roller, by making at the air quantity (units/kg/s) of the wind blowing out from said nozzle and the long-pending swing roller volume (unit liter) that is multiplied by of wind speed (m/s of unit), by the value that the quality (units/kg) of clothing is removed, be also more than 62, do not rely on the amount of volume and the clothing of swing roller, just can effectively flatten the fold of clothing.

On the air entry of outlet 2b, wind pushing mechanism 28 and outlet, be provided with temperature sensor (not shown).
The invention is characterized in, wind at a high speed is directly blown on clothing, by the power of wind, flatten the fold resulting from clothing.For this reason, need produce the wind pushing mechanism 28 of wind at a high speed and this wind is directly blown to the warm air blow-off outlet 32 on clothing.For the required performance of wind pushing mechanism, be described later.Use Fig. 6, Fig. 7 that the detailed content of warm air blow-off outlet 32 is described.Fig. 6 is the front view of the outer bung 2d of warm air blow-off outlet 32 setting units, and Fig. 7 cuts off the cutaway view of the warm air blow-off outlet 32 representing at the double dot dash line A-A place of Fig. 6.
Warm air blow-off outlet 32 arranges along peristome 2c from the front side of outer bung 2d, is formed with stream 32b, 32c in inside.Entrance at warm air blow-off outlet 32 is provided 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 as roughly the same, to prevent entering clothing in the gap of washing and dewatering bucket 3 and outer bung 2d.Therefore, the 32a of export department of warm air blow-off 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, from the warm air of nozzle 32d ejection, directly blow to the clothing in washing and dewatering bucket 3.
And the overhang of the 32a of ，Ruo export department is too much, hinder the motion of washing and clothing when dry, therefore as shown in Figure 7, nozzle is made to flat kerf and reduce overhang, and the surface configuration of the peristome 2cHe 32a of export department changes smoothly.In addition, stream 32b and stream 32c make the variation that there is no useless projection and flow direction sharply, 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.
Flowing of wind during dry operating is as follows.If running wind pushing mechanism 28, and to heater 31 energising, is blown into warm air (arrow 41) at a high speed in from nozzle 32d to washing and dewatering bucket 3, blow on moist clothing the clothing from clothing transpiring moisture of heating.The air that becomes high temperature and humidity flows to outer barrel 2 from the through hole being located at washing and dewatering bucket 3, from air entry 2a, sucks in dry channel 29, and in dry channel 29, flow from the bottom up (arrow 42).On the wall of dry channel 29, flow down the cooling water from water-cooled desiccant body, the air of high temperature and humidity and cooling water are removed and the dehumidifying that is cooled becomes dry Cryogenic air and enters filter passage 27 (arrow 43).By the gauze filter 8a being located on filter passage 27, remove the end of a thread, and enter air intake passage 33, be drawn into wind pushing mechanism 28 (arrow 44).And, with heater 31, again heat, be blown in washing and dewatering bucket 3 and circulate.In the meantime, make washing and dewatering bucket 3 with low speed positive and negative rotation, by clothing be promoted to nozzle 32d near, wind at a high speed is directly blown on clothing.
Fig. 8 is an example of having investigated having carried out the wind speed spraying from nozzle 32d of occasion of dry operating as above and the result of the quality condition of dried clothing.Wind speed and air quantity regulate by changing the revolution of motor 28a and the area of nozzle 32d.In addition, the value that wind speed calculates according to the result of having measured the air quantity pressure characteristic of wind pushing mechanism 28.Air quantity pressure characteristic is measured with the device shown in Figure 13.On the air entry of surge tank and the outlet of wind pushing mechanism 28, throttle orifice is installed, when the revolution of the diameter of throttle orifice and motor 28a is carried out to various changes, measure air quantity and the air entry of wind pushing mechanism 28 and the pressure of outlet, obtained air quantity pressure characteristic.And, measure the air entry of wind pushing mechanism 28 and the pressure of outlet when wind pushing mechanism 28 is arranged on scrubbing-and-drying unit, according to above-mentioned air quantity characteristic, obtain air quantity, the value that this air quantity is removed by nozzle area is as wind speed.
As shown in FIG., testing machine is the drum-type washing drying machine with the washing and dewatering bucket of diameter 600mm and volume 75L to experiment condition, and cloth amount is 2kg.The evaluation of quality is carried out with various clothings, but has represented the thinnest pyjama result of cotton of fold.Evaluation is according to the sense evaluation in 5 visual stages, will the example of the quality condition of sense evaluation of estimate be represented with Figure 14.From the blow-off direction of the wind of nozzle 32d roughly towards the diapire central authorities of washing and dewatering bucket 3.Result is 3 of estimators' mean value.As a reference, the quality condition that is not dried after will washing and directly hangs the occasion of drying represents with Figure 15.(a) being the situation of convection drying after dehydration, is (b) to carry out dry situation after flattening gently dehydration fold.(a) be dry with dehydration fold, sense evaluation of estimate is 4 left and right, is (b) that dehydration fold has reduced still also residual a lot of shallow fold, and sense evaluation of estimate is 4.5 left and right.
As we know from the figure, (A) along with uprising quality, wind speed improves.But also find for wind speed quality saturated, if the too high tendency of contrary deterioration of wind speed.And air quantity is 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 sense evaluation of estimate is about 3, air quantity 1.0m
3during/min, wind speed is about 130m/s and sense evaluation of estimate is about 3.3, air quantity 1.3m
3during/min, wind speed is about 120m/s and sense evaluation of estimate is about 3.9, air quantity 1.5m
3during/min, wind speed is about 110m/s and sense evaluation of estimate is about 4.0, air quantity 1.7m
3during/min, wind speed is about 100m/s and sense evaluation of estimate is about 4.2, even if increase wind speed more than this, quality also improves hardly.And, at air quantity, be 1.5m
3when/min is above, obtained the quality equal with fesloon drying.
(B) if the many side's better quality of the identical air quantity of wind speed, but air quantity is from 1.5m
3/ min rises to 1.7m
3the improvement degree of quality during/min reduces.Hence one can see that, even if the necessary above air quantity that increases can not be expected the improvement of quality.
Like this, wind speed, the larger quality of air quantity are better.Air quantity and wind speed are not to strengthen a wherein side, and preferably consider that both balances set.Specifically, need not merely considering 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, to the installation of scrubbing-and-drying unit etc., decide wind speed and air quantity.
If sense evaluation of estimate is more than 3, even if also can complete simply in the occasion that is dried after-applied ironing, if sense evaluation of estimate is more than 4, even if it is discontented also few directly to wear dried clothing.In order to make sense evaluation of estimate, be more than 3, air quantity 0.8m
3more than during/min, wind speed is about 140m/s, air quantity 1.0m
3more than during/min, wind speed is about 110m/s, air quantity 1.3m
3more than during/min, wind speed is about 92m/s, air quantity 1.5m
3more than during/min, wind speed is about 75m/s, air quantity 1.7m
3more than during/min, wind speed is about 70m/s, the minimum 0.8m that also needs
3the air quantity of/min.In addition, air quantity has a significant impact drying property, but because air quantity is crossed, I haven't seen you for ages extends drying time, therefore from the viewpoint of drying property, considers, air quantity also needs 0.8m
3more than/min.
Be not easy the occasion of the clothing of fold, than above-mentioned low value, also can have obtained more than 3 quality of sense evaluation of estimate, but be to be generally dried various clothings simultaneously, so merge with the clothes that easily plays fold, determined wind speed.
With Fig. 9 illustrate by by wind at a high speed to the reason that reduces the fold of clothing on clothing.Fig. 9 (a) is wind 41 from the high speed of the nozzle 32d ejection ideograph during with clothing collision.At this, there is the situation of other clothings at the back side that is illustrated in clothing.If wind and clothing collide, on clothing, make the power (arrow (1)) and the power (arrow (2)) to stretch along the surperficial mobile wind left and right of clothing with clothing collision rear change flow direction that in order to wind, extend.By the power of this (1) and (2), flatten the fold of clothing.The occasion that the amount of the clothing in washing and dewatering bucket 3 is many, has a lot of other clothings and can not freely-movable in the surrounding that directly blows to the clothing of wind, therefore mainly with the power of (1), flattens fold.In the few occasion of the amount of clothing, clothing freely-movable, it is such that the clothing that blows to wind becomes sail when flow direction aweather flattens, also acts on by the power along the mobile wind caused (2) in clothing surface and flatten fold.In the few occasion of the amount of clothing, dry middle clothing easily launches, and is difficult to produce fold, so consider the power of (1) at this.
(1) power F, as shown in Fig. 9 (b), if the air quantity of the wind blowing out from nozzle 32d is Q, wind speed while being V, can represent with the long-pending of Q and V.And, the wind blowing out from nozzle 32d (jet flow) is by the effect of the viscosity of the larger speed difference with ambient air and air, be involved in ambient air and expand mobile width, and now jet flow flows (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 approximately 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 subject to (pressure that clothing is subject to from wind) reduces.Thereby approximately near nozzle 32d, the effect that flattens fold is larger by clothing.
The result of Fig. 8 F that exerts oneself is rearranged, become as shown in figure 10.And, in Fig. 8, air quantity Q is represented by volume flow, and the density that is multiplied by air at this (is 1.24kg/m 20 ℃ time
3) be converted to mass flow.As we know from the figure, with putting forth effort F, increase quality official and can evaluation of estimate rise, but be that 3.5N is roughly saturated when above at power F, sense evaluation of estimate is about 4.7 left and right.Although sense evaluation of estimate has fluctuation a little, enter in the scope of dotted line of figure.Hence one can see that, in order to make sense evaluation of estimate, is more than 3, and the F that exerts all one's strength is about 2.2N above.
Figure 11 has summed up the figure of the experimental result of cloth amount from 1kg to 4kg equally with Figure 10.As we know from the figure, cloth amount is more, for obtaining identical sense evaluation of estimate, needs larger power F.This be because, the more heterogeneous amount to the clothing of the volume of washing and dewatering bucket 3 of cloth amount increases, clothing is difficult to launch, therefore flattening fold needs larger power.And, saturated in the above sense evaluation of estimate of a certain power, therefore according to cloth amount, for acting on best power, control air quantity, wind speed, thereby do not circulate useless wind, obtain best quality, can reduce power consumption.As the control method of air quantity, wind speed, the easiest is the method for controlling the revolution (cloth amount increases and more improve revolution) of wind pushing mechanism 28, but can be also the method that the area of change nozzle 32d carrys out control area.
Along with cloth amount increases, the maximum of sense evaluation of estimate reduces, and when cloth amount 1kg, official can evaluation of estimate be about 4.8, during cloth amount 2kg, is about 4.7, during cloth amount 3kg, is about 4.2, during cloth amount 4kg, is about 3.5, during cloth amount 5kg, is about 2.6.In this figure, for obtaining the more than 3 required power F of sense mean value, be about 0.8N when cloth amount 1kg more than, more than being about 3.0N during 3kg, more than being about 3.4N during 4kg.In this experiment, when cloth amount 5kg, do not reach sense evaluation of estimate 3.From above content, even be more than 0.8N relatively good at the few occasion of the cloth amount F that also will exert all one's strength.
Like this, according to the volume of washing and dewatering bucket 3 and cloth amount, for obtaining the power difference of necessary quality.So, the volume of the washing and dewatering bucket 3 of every cloth amount is defined as to volumetric ratio (volume/cloth amount of=washing and dewatering bucket 3).Then, the long-pending result that arranges Figure 10 with power F and volumetric ratio, obtains Figure 12.As we know from the figure, long-pending for power and volumetric ratio, quality evaluation value enters in the scope of dotted line of figure.This figure comprises the index relevant to dry mass (volume of power F, washing and dewatering bucket 3, cloth amount), by using this figure, can derive for obtaining the condition of aimed quality.
In order to make sense evaluation of estimate, be more than 3, the long-pending of power and volumetric ratio is made as to about 62NL/kg above.As an example, when volume 75L, the cloth amount 4kg of washing and dewatering bucket 3, obtain for obtaining more than 3 condition of sense evaluation of estimate.
Volumetric ratio=75/4=18.75L/kg, power F=62/18.75=3.31N.Then consider drying property and air quantity is decided to be to 1.65m
3/ min (=0.0341kg/s), wind speed is about 97m/s (=3.31/0.0341).Therefore,, in order to obtain this air quantity, wind speed, the area of nozzle 32d is set as to 2.83 * 10

In present embodiment example, wind pushing mechanism 28 its blast fan diameters are that 140mm, impeller thickness are that 8.1mm and revolution are per minute 15000 to turn.Fan discharge pressure becomes about 7000Pa (air themperature 30 ℃ time) thus, obtains above-mentioned air quantity, wind speed.
As mentioned above, for quality is become well, increased force will F (increase air quantity Q or increase wind speed V), and reduce the distance X of nozzle and clothing can (making clothing near nozzle).
In order to increase air quantity Q, need to improve the revolution of the fan of wind pushing mechanism 28, or increase external diameter and the impeller height of fan.And it is relatively good that the area of the passage that increasing warm air is passed through reduces the pressure loss.Especially, in dehumidifying, make the occasion of the water-cooling pattern of water, if too fast at the flow velocity of the interior mobile air of dry channel 29, produce the phenomenon that cooling water is blown to four winds.If cooling water arrives filter 8a and heater 31, because filter 8a is wetting, increase stressed loss and with heater 31 evaporative cooling water, reduce the temperature etc. of warm air, 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, the size of passage and wind pushing mechanism becomes large, causes the change of size of cabinet 1 large, is difficult to by scrubbing-and-drying unit setting in the family.
On the other hand, in order to increase wind speed V, wind pushing mechanism 28 is made to pressure type and reduced nozzle area.As wind pushing mechanism 28, using the occasion of general turbofan, existence is with low revolution and strengthen the method for diameter of blast fan and the diameter of blast fan is little and improve the method for revolution, and High Rotation Speed has advantages of and can be arranged on cabinet as in the past.
From the experiment structure of the quality shown in Fig. 8, find, if the phenomenon of the too high deterioration of wind speed.This can not illustrate with foregoing.If the motion of the clothing in observation experiment, if the too high phenomenon that produces clothing distortion due to the impetus of wind of known wind speed.The reason of deterioration that therefore, Here it is.
In order to reduce the distance X of nozzle 32d and clothing, suitably control the revolution of washing and dewatering bucket 3, clothing is promoted near nozzle 32d, and makes wind at a high speed directly blow on clothing as far as possible.Clothing is by using the caused centrifugal force of rotation and lifter 3b by washing and dewatering bucket 3 to draw and promote upward.Therefore, revolution has optimum value according to the diameter of washing and dewatering bucket 3, and the larger revolution of diameter is lower.In addition, lifter 3b height is relatively good.But if the height of lifter 3b is high, promoting the clothing be immersed in water needs high torque (HT), need to use the motor 4 of high-output power, therefore need to consider the power output of motor and determine the shape of lifter 3b.
In order further to shorten the distance X of nozzle 32d and clothing, near must dividing by the place of clothing, nozzle 32d is set when dry.That is, the position of nozzle 32d is arranged on to the downside (downside of outer bung 2d) that is promoted the washing and dewatering bucket 3 of clothing by lifter 3b.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 just can obtain the quality of same degree than nozzle in the power of upper occasion about little 30%.The long-pending value of the power F shown in Figure 12 and volumetric ratio also can reduce 30%, in order to obtain sense evaluation of estimate, more than 3 is set as 44NL/kg above.Like this, have advantages of with nozzle 32d and can reduce pressure and the air quantity (can reduce the revolution of blast fan) of blowing unit 28 in upper occasion comparison.And, if nozzle 32d under, the blow-off direction of wind and the opposite direction of gravity.In wind, on clothing time, because the deadweight clothing of clothing is difficult to escape, the F that can exert all one's strength acts on clothing effectively.
Figure 17 is the block diagram of the control device 38 of scrubbing-and-drying unit.The 50th, microcomputer, be connected to each switch 12,13, the upper action button input circuit 51 of 13a is connected with level sensor 34, temperature sensor 52, carry out user's push-botton operation and receive the various information signals in washing procedure, drying process.From the output of micro computer 50, be connected with drive circuit 54, and be connected with water-suppling electromagnetic valve 16, draining valve 25, motor 4, wind pushing mechanism 28, heater 31 etc., control their switch and rotation, energising.And, and for notify seven sections of light emitting diode indicators 14 of the operating state of washing machine to be connected with light emitting diode 56, buzzer 57 to user.
Above-mentioned microcomputer 50 starts starting while switching on power at pushing power switch 39, carry out washing as shown in figure 18 and dry basic control handling procedure.
Step S101
Carry out state confirmation and the initial setting of scrubbing-and-drying unit.
Step S102
Light the display 14 of guidance panel 6, according to setting washing/drying process from the indication input of pushbutton switch 13.Under the state of not indication input, the washing/drying process of automatically implementing the washing/drying process of established standards or last time.For example, in indication, input the occasion of pushbutton switch 13a, set dry high-quality process.
Step S103
The indication from starting switch 12 of supervisory work panel 6 is inputted and branch process.
Step S104
Wash.Washing is washed successively, middle dehydration, rinsing, final dewatering, identical with general drum-type washing drying machine, so detailed.
Step S105
Be confirmed whether to set washing dry run branch process.In the occasion of only setting washing process, finish running.
Step S106
In the occasion of setting washing dry run, carry out warm air dehydration.Warm air dehydration is with the low speed rotation wind pushing mechanism 28 that turns round, and to heater 31 energisings (strong mode) thus and make warm air be blown into the temperature that improves clothing in washing and dewatering bucket 3.Meanwhile, make washing and dewatering bucket 3 high-speed rotaries transfer effectively to slough moisture (while rising due to temperature, the viscosity of water declines so can effectively dewater) from the clothing of heating.In present embodiment example, the revolution of wind pushing mechanism 28 is set as to per minute 11000 and turns.This be because, in order to prevent from surpassing allowable current value (15A).
Step S107
Carry out dry operating 1.Wind pushing mechanism 28 low speed rotation, heater 31, with strong mode running, carries out the positive and negative rotation of washing and dewatering bucket 3 repeatedly, in the position of the clothing in transposing washing and dewatering bucket 3, the warm air of high temperature is blown on clothing.The all temperature of clothing rises and from clothing transpiring moisture.
Step S108
Be confirmed whether to set high-quality process branch process.The occasion of the process beyond high-quality process, carries out step S107 until dry end.
Step S109
Whether confirmation reaches official hour branch process from being dried the elapsed time starting.Official hour be set as aridity than clothing (quality of the quality of=dry cloth/wet cloth) reach 0.9 before.
Be dried and carry out as follows.At the dry initial stage, between the warming up period rising in the temperature that makes clothing, in order to make the temperature fast rise of clothing, by as far as possible many heats, give clothing important.Between warming up period, few from the evaporation of the moisture of clothing.
Along with the temperature of clothing rises, from the evaporation of the moisture of clothing, become many, therefore because rising the temperature of clothing, heat of gasification latens, and heating and heat of gasification reach balance soon, the temperature of clothing become roughly necessarily (constant-rate method of drying).If the amount of moisture of clothing tails off, heat of gasification reduces, and the temperature of clothing starts to rise again, if the disappearance of the moisture of clothing becomes the temperature roughly the same with warm air and finishes to be dried (lapse rate is dry).The moment that the temperature of clothing starts to rise is near aridity reaches 0.9 time.
At clothing, comprise very juicy time, though on clothing, rise fold also can flatten simply (from fold clothing spraying or with steam give moisture fold disappear also can know).But, rise under the state of fold dry proceed to aridity be more than 9.0 fold be fixed.Fixing fold is once eliminated almost and can not be accomplished by operation afterwards.Therefore, before aridity becomes 0.9, flatten fold and become important.
When reality dry, the dry material clothing different with thickness simultaneously, so aridity becomes time of 0.9 also according to clothing and difference.Therefore,, in present embodiment example, the aridity that is set as the most easily rising the thin cotton dress thing of fold becomes the time of 0.8 to 0.85 left and right.And, according to cloth amount aridity, become 0.9 asynchronism(-nization), therefore certainly also need to carry out setting-up time according to cloth amount.
Step S110
Carry out dry operating 2.The positive and negative rotation of washing and dewatering bucket 3 is proceeded, and by wind pushing mechanism 28 High Rotation Speeds, heater is set as to weak pattern and clothing blowing up in washing and dewatering bucket 3 wind at a high speed, when flattening fold, is dried.When High Rotation Speed wind pushing mechanism 28, heater 31 being set as to weak pattern, is in order to prevent from surpassing allowable current value.In present embodiment example, the revolution of wind pushing mechanism 28 is set as to per minute 16000 and turns.The input current of per minute 16000 wind pushing mechanisms 28 while turning 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 decline with step S107.If especially aridity surpasses the temperature rising of 0.9 clothing, move closer to warm air temperature, but because warm air temperature is low, the temperature that therefore can suppress clothing is low, also has advantages of the damage that can alleviate clothing.
Be dried when utilizing temperature sensor monitors warm air and cooling water drainage coolant-temperature gage and 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 cloth quantitative change is many, the transposing of the inboard in 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 air.Therefore, by from first with High Rotation Speed wind pushing mechanism 28, even if rate of drying has the great fluctuation process of adding, also can prevent from playing fold on quick-drying clothing.
