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, suck in the dry channel 29 from air entry 2a, and in dry channel 29 mobile (arrow 42) from the bottom up.On the wall of dry channel 29, flow down cooling water from the water-cooled desiccant body, high temperature how remove and the dehumidifying that is cooled by wet air and cooling water, becomes dry Cryogenic air and enter 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.
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, the value calculated according to the result of the air quantity pressure characteristic of having measured wind pushing mechanism 28 of wind speed.The air quantity pressure characteristic is measured with device shown in Figure 10.On the outlet of the air entry of surge tank and wind pushing mechanism 28, throttle orifice is installed, when the revolution 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 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 751, 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 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 situation (position that the right bank of outer bung 2d makes progress) that nozzle 32d is set in above-mentioned position, and following nozzle is arranged on the situation of the bottom of outer bung 2d.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) along with uprising quality, wind speed improves.But if the too high then opposite deterioration of wind speed is (from top nozzle 1.5m
3The data of/min as can be known).
(B) if the many square better quality of the identical then air quantity of wind speed, but flow 1.5m
3/ min and 1.7m
3Difference during/min is little.
(C) if compare, then descend nozzle than top nozzle better quality with identical wind speed, flow.
Like this, the big more quality of wind speed, air quantity is good more, but how relatively good flow is also to a certain extent.Therefore, be not to strengthen a wherein side, and consider that preferably both balances set.Specifically, need not merely consider quality, also to consider current value (occasion of home-use 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 4, even it is discontented also few then directly to wear dried clothing.In order to make the sense evaluation of estimate in this experimental machine is more than 4, in the occasion of top nozzle, needs flow 1.5m
3/ min, more than the wind speed 90m/s.But if the too high tendency that then has deterioration of wind speed, therefore the highest wind speed 130m/s that also will be controlled at is relatively good.And quality becomes better when wind speed 100～120m/s.Occasion at following nozzle needs flow 1.5m
3/ min, more than the wind speed 60m/s, but since when wind speed 80m/s is above quality condition change hardly, therefore get final product about maximum 80m/s.Being used to obtain 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
2Therefore, wind pushing mechanism 28 need have from only the circulate performance of above-mentioned flow of the nozzle of above-mentioned area.In the present embodiment example, be top nozzle, nozzle area 250mm at nozzle location
2When (on the otch of width 50 * height 50mm), wind pushing mechanism 28 its blast fan 140mm, impeller thickness 7mm and be that per minute 16000 changes and turns round with the revolution.Thus, the fan discharge pressure becomes about 7000Pa (air themperature 30 ℃ time), obtains the about 1.5m of flow
3/ min, the about 100m/s of wind speed.
Be not easy the occasion of the clothing of fold, the value lower than above-mentioned wind speed also can obtain the quality of sense evaluation of estimate more than 4, but generally is dry various clothings of while, and the decision wind speed gets final product so merge with the clothes that plays fold easily.
Use Figure 12 to illustrate that the wind by will be at a high speed reduces the reason of the fold of clothing 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 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 Figure 12 (b), if the air quantity of the wind that blows out from nozzle 32d be Q, when wind speed is V, long-pending proportional with Q and V.And when if the distance of nozzle 32d and clothing is X, power F and V are proportional and be inversely proportional to X.But in the very approaching occasion of the distance X of nozzle 32d and clothing (central area of jet flow is in the position of occasion from nozzle to about 6 times nozzle diameter of round nozzle), F and X are irrelevant and proportional with V.Therefore,, increase flow Q or increase wind speed V, perhaps reduce X and get final product (with the close nozzle of clothing) if want increased force will F.Can illustrate with this with quality results shown in Figure 8.
In order to increase flow Q, need the revolution 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 cause the significantly reduction of drying efficiency, therefore must strengthen the flow path area of dry channel 29.Therefore, if increase considerably flow, 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 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 at a high speed rotation have can be installed in identical in the past cabinet on advantage.
From the experiment structure 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, near when drying, must dividing nozzle 32d is set and gets final product by the place of clothing.Therefore, the position of nozzle 32d is arranged on the position that is promoted clothing by lifter 3b, and promptly the downside of washing and dewatering bucket 3 (downside of outer bung 2d) gets final product.Below nozzle is located at, quality is become well, therefore, have the advantage that can reduce the pressure and the flow (can reduce the revolution of blast fan) of blowing unit 28 with nozzle in last occasion comparison.And following, then the direction of the blow-off direction of wind and gravity is opposite as if nozzle.When wind was to clothing, because the deadweight clothing of clothing is difficult to escape, the power F that acts on the clothing can not decay, and therefore had to make the quality better advantage that becomes.
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.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.
In the present embodiment example,, therefore do not worry that washings enter owing to the position that the right bank that nozzle 32d is located at outer bung 2d makes progress.In this occasion, need the suitably revolution of control washing and dewatering bucket 3, clothing can be promoted to nozzle 32d near, and make wind at a high speed to clothing as far as possible.Clothing is by being promoted upward by caused centrifugal force of the rotation of washing and dewatering bucket 3 and lifter 3b.Therefore, revolution is that the diameter according to washing and dewatering bucket 3 has optimum value, and the big more revolution of diameter is low more.But, the clothing that falls early because of gravity is also arranged, average nozzle is more elongated than the occasion that nozzle is located at downside with the distance of clothing to be inevitably, therefore needs to improve the wind speed of jet expansion as shown in Figure 8.

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 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 9.0 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
Carry 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 is set at weak pattern and blows wind at a high speed on the clothing washing and dewatering bucket 3 in, carries out drying in the 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, the revolution of wind pushing mechanism 28 is set at per minute 16000 to be changeed.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 because warm wind-warm syndrome degree is low, the temperature that therefore can suppress clothing is low, also has 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 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 the great fluctuation process of adding.
