Be provided with water-suppling electromagnetic valve 16 and water for bathing supply-water pump 17, level sensor (not shown) etc. and the parts that supply water and be associated at the rear side of detergent container 19.Cover the soft suction hose connector 17a that 1e is provided with the surplus water of the water supply hose connector 16a that is connected with water tap, sucking-off water for bathing in the above.Detergent container 19 is connected with water jacket 2, perhaps turns round water for bathing supply-water pump 17 and supplies with washings to water jacket 2 through opening water-suppling electromagnetic valve 16.
The top of drying duct 29 is connected with the filter pipeline 27 of upper right be arranged at casing 1 along fore-and-aft direction in.The connecting portion with filter pipeline 27 on drying duct 29 tops has suction air valve 55.Have peristome in filter pipeline 27 fronts, drawer type device for drying and filtering 8 is inserted in this peristome.The air that gets into filter pipelines 27 from drying duct 29 flow into the device for drying and filtering 8 gauze filter 8a and removes the line bits.The cleaning of device for drying and filtering 8 is carried out through gauze filter 8a is pulled out and taken out to device for drying and filtering 8.In addition, below device for drying and filtering 8 insertion sections of filter pipeline 27, be provided with peristome, this peristome is connected with aspirating air pipe 33, and the other end of aspirating air pipe 33 is connected with the air entry of blowing unit 28.
In the present embodiment; Because blowing unit 28 is arranged on the upper right in the casing 1; Thereby anterior purge port 32 is arranged on the position of the right oblique upper of outer capping 2d, and shortening to the distance of anterior purge port 32 as far as possible, thereby the pressure loss of making and distributing of heat reach Min..But because rear portion purge port 52 is arranged on the point-symmetric basically position of air entry 2a with the drying duct 29 of upper rear portion, thereby the length of rear portion pipeline 51 is longer, pipeline 51 heat radiations from the rear portion easily.Therefore, rear portion pipeline 51 and water jacket 2 are arranged to fit tightly.The heat that so, can reduce the warm braw that is heated by heater 31 is distributed in casing in the process through rear portion pipeline 51.Have again; Because the cross sectional shape of rear portion pipeline 51 is made the コ font; And the outer peripheral face of open side and water jacket 2 is fitted tightly, the method for using the outer peripheral face of water jacket 2 to constitute rear portion pipeline 51 has reduced the heat dissipation of pipeline area, thereby can further increase and prevent the effect of dispelling the heat.
Air entry and outlet at water discharge outlet 2b, blowing unit 28 are provided with temperature sensor (not shown).
The invention is characterized in, make at a high speed wind directly and contact with clothing, the wrinkle of clothing is stretched, promote moisture to evaporate on one side, and according to the purge port of carrying out degree conversion warm braw of drying, thereby reduce the inequality of drying, reduction power consumption from clothing.The blowing unit 28 that for this reason, must produce wind at a high speed with make this wind directly and anterior purge port 32, the rear portion purge port 52 of contact with clothing.The needed performance of relevant blowing unit will in after state.
Below, use Fig. 7, Fig. 8 to specify anterior purge port 32.Fig. 7 is the front view that anterior warm braw purge port 32 is provided with the outer capping 2d of portion, and Fig. 8 is the cutaway view that dissects the anterior purge port of representing 32 with the double dot dash line A-A line of Fig. 7.
In addition; If the overhang of the 32a of export department is excessive, owing to can hinder the activity of clothing, thereby as shown in Figure 7 nozzle is made flat shape of slit and made overhang less in washing and when dry; And, the surface configuration of peristome 2c and the 32a of export department is changed smoothly.And, make runner 32b and 32c not have the rapid variation of the useless projection and the flow direction, and the flow area towards nozzle 32d diminished gradually.So, can reduce the distinguished and admirable pressure loss and the fluid sound that when runner 32b, 32c, is produced at a high speed.
The switching valve 54 that is arranged in the corrugated pipe connector 30b is made up of drive motor 54a and valve body 54b.Drive motor 54a is installed on the corrugated pipe connector 30b with retaining element 54c.Through make the rotating shaft 54d rotation that is arranged at valve body 54b end make valve body 54b rotation with drive motor 54a.Be defined as when valve body 54b is positioned at position shown in Figure 8 and close switching valve, be defined as when valve body 54b is positioned at the position of double dot dash line and open switching valve.In the occasion of closing switching valve 54; Owing to closed backside openings 30c, thereby warm braw blows from anterior purge port 32, if open switching valve 54; Then because of having closed to the air channel of anterior purge port 32, purge port 52 blows warm braw from the rear portion through rear portion pipeline 51 from backside openings 30c.
Below, use Fig. 9, Figure 10 to specify the situation of rear portion purge port 52 parts.Fig. 9 is the cutaway view at the rear portion of the water jacket that dissects of the double dot dash line B-B line with Fig. 4 and washing and dewatering groove 3.Figure 10 is that the C-C line with Fig. 9 dissects water jacket 2 and washing and dewatering groove 3, representes the cutaway view of the bottom surface of washing and dewatering groove 3.
Be provided with rear portion purge port 52 and air entry 2a in the bottom surface of water jacket 2, air entry 2a is positioned at the water jacket bottom, and rear portion purge port 52 is arranged on water jacket top, and both roughly are in point-symmetric position with respect to the rotating shaft 4a of motor 4.In addition, the radial position of air entry 2a is in the position near the most peripheral side, and rear portion purge port 52 is positioned in the inner part by comparison.Than the position of air entry 2a inner all sides, depending on the teat B53b that is formed with a plurality of ring-types on the outer groove bottom of outer circumferential side than rear portion purge port 52.In addition, the water jacket side is formed with the teat A53a with the concentric a plurality of ring-types of teat B53b in the bottom surface of washing and dewatering groove 3.Teat B53b disposes with teat A53a is mutual differently, thereby constitutes labyrinth sealing 53.On the bottom surface of the washing and dewatering groove 3 relative with rear portion purge port 52, be provided with a plurality of blow vent 3d, blow vent 3d constitutes netted or is made up of many apertures, in order to avoid clothing flies out and reduces aeration resistance.In addition, be provided with a plurality of aperture 3e in the outer part in labyrinth sealing 53 than washing and dewatering groove 3 bottom surfaces.
Like this; Position through making rear portion purge port 52 and air entry 32 remotely disposes; And between is provided with labyrinth sealing, thereby can prevent that the warm braw that purge port 52 blows from the rear portion from directly getting into air entry 2a, can make the contact with clothing in wind and the washing and dewatering groove 3 effectively.In addition; Because the wind speed of the warm braw that purge port blows from the rear portion reaches the high speed of the degree of the wrinkle stretching, extension that can make clothing; Even thereby in washing and dewatering groove 3, put into a large amount of clothings and clothing stopped up under the situation of blow vent 3d; Because clothing is formed the gap by the wind-force pushing between clothing, owing to warm braw is easy to enter in the washing and dewatering groove 3, thereby also can make wind and contact with clothing effectively.
In the example of this embodiment, make the wind speed of the warm braw that purge port 52 blows from the rear portion slower, to reach the degree of the effect (making the effect of clothing expansion) that the wrinkle that do not hinder clothing stretches than the wind speed that blows from anterior purge port 32.Usually, make on washing and dewatering groove 3 to install and have the bead 23 of many radial ribs, connect the structure of the rotating shaft 4a of motor 4 at the central part of this bead 23.If washing and dewatering groove 3 rotation, then radial rib be crosscut rear portion purge port 52 periodically just.Therefore,, then blow sound of the wind, noise is increased, thereby wind speed is slowed down, then suppressed to blow the increase of sound of the wind owing to producing if the wind speed of purge port 52 is too fast at the rear portion.
In fact, do the nozzle area of rear portion purge port 52 bigger than the area of the nozzle 32d of anterior purge port 32.Revolution at blowing unit 28 is certain occasion, though the wind wind speed that purge port 52 blows from the rear portion is more slack-off than the wind that blows from anterior purge port 32, air quantity increases.Though the moisture that is caused by wind speed reduces from the effect that clothing evaporates, owing to cancelling out each other with the effect raising that increases the water evaporates that causes by air quantity and can not reducing drying efficiency.
Position facing with the rear portion purge port 52 of bead 23 is provided with blow vent 23a, also is provided with a plurality of aperture 3f in the outer groove bottom that covers bead, even bead 23 is come under the situation of rear portion purge port 52, warm braw also can enter in the washing and dewatering groove 3.In addition, the shape of rear portion purge port 52 is preferably in the circumferencial direction slit-shaped longer than the width of the radial rib of bead 23.So, owing to rear portion purge port 52 can not sealed by the rib of bead 23 fully, thereby can warm braw be imported in the washing and dewatering groove 3 effectively.
Figure 11 representes the detailed structure of suction air valve 55.Figure 11 is the double dot dash line D-D line side cross sectional view with Fig. 4.Suction air valve 55 is made up of drive motor 55a, valve body 55b and valve seat 55c.Rotate through the rotating shaft 55d that makes the central part that is arranged at valve body 55b with drive motor 55a and to make valve body 55b rotation.Shown in figure 11, will be called with the state of valve body 55b closed valve seat 55c and close the suction air valve; As with shown in the double dot dash line, the state of blocking-up drying duct 29 and filter pipeline 27 is called opens the suction air valve.If make suction air valve 55 be in open mode, then form air entry 56 and exhaust outlet 57.Air entry 56 is opened on the inner space of the upper cover 1e on casing 1 top.Exhaust outlet 57 is connected with discharge duct 58, and leads to indoor.Outlet at discharge duct 58 is provided with filter 59, is used for removing line bits contained in the exhaust.
Though flowing of the wind during dry operating utilizes the on off state of switching valve 54 and the on off state of suction air valve 55 can realize four kinds of current methods, in the present invention, carries out switching valve 54 and suction air valve 55 two types of runnings that both close or both open.In addition, though flowing of wind in Fig. 1 to Fig. 5 and Fig. 8 to Figure 11, represent with solid arrow and dotted arrow, for easy understanding, represent with the structural representation of Figure 12.The situation of at first, both being closed is narrated (solid arrow of Figure 12).If running blowing unit 28 to heater 31 energisings, then blows warm braw (arrow 41) at a high speed from nozzle 32d in washing and dewatering groove 3, warm braw and wet contact with clothing make moisture evaporate from clothing to the clothing heating.How wet air flows to water jacket 2 from the through hole that is arranged on the washing and dewatering groove 3 to become high temperature, is drawn in the drying duct 29 from air entry 2a, and (arrow 42) from bottom to top flows in drying duct 29.Fall from the cooling water flow of water-cooled desiccant body on the wall of drying duct 29, the air that high temperature is how wet carry out cooling and dehumidifying through contacting with cooling water, become dried Cryogenic air and get into filter pipeline 27 (arrow 43).Gauze filter 8A through being arranged in the filter pipeline 27 removes the line bits, gets into aspirating air pipe 33, is sucked (arrow 44) by blowing unit 28.Then, by heater 31 heating, be blown into the circulation in the washing and dewatering groove 3 once more.Utilize this circulation to form first drying (circulation) path as dehumidification mode., make washing and dewatering groove 3 therebetween,, make warm braw at a high speed directly and contact with clothing up to clothing being risen near the nozzle 32d with the low speed rotating.
Secondly, under the situation that both open (dotted arrow of Figure 12), if running blowing unit 28, then the air of casing 1 just is inhaled into (dotted arrow 46) the filter pipeline 27 from air entry 56.Then; Get into aspirating air pipe 33, sucked (dotted arrow 63), get into rear portion pipeline 51 (dotted arrows 47) from corrugated pipe connector 30b by blowing unit; Be directed to the back side of water jacket 2 by the rear portion pipeline; From the rear portion purge port 52, be blown in the washing and dewatering groove 3 (dotted arrow 48) from the rear side of washing and dewatering groove 3, the contact with clothing with inboard in the washing and dewatering groove 3 make moisture evaporate from clothing.Then, air flows to water jacket 2 from the through hole that is arranged at washing and dewatering groove 3, and is pressed into drying duct 29 (dotted arrow 62) from air entry 2a.Air flows from bottom to top in drying duct 29 and gets into discharge duct 58 from exhaust outlet 57, removes line bits back with filter 59 and outside machine, discharges (dotted arrow 45).Thus, formation is as second drying (circulation) path of exhaust mode., make washing and dewatering groove 3 therebetween, clothing is risen near the rear portion purge port 52 wind is directly contacted with clothing with the low speed rotating.
Drying is carried out as follows.The dry initial stage for the temperature that makes clothing rises rapidly, is importantly supplied heat as much as possible to clothing between the warming up period that the temperature that makes clothing rises.Between warming up period, reduce from the clothing moisture evaporated.
Along with the rising of clothing temperature, owing to increase from the clothing moisture evaporated, owing to heat of gasification makes the rising of clothing temperature slack-off, heating soon reaches balance with heat of gasification, and the temperature of clothing almost keeps constant (constant rate of drying).After beginning to increase from clothing moisture evaporated amount, open water-suppling electromagnetic valve 16, the water-cooled desiccant body to drying duct 29 in is supplied with cooling water, makes the many humid air coolings dewfall also that comprises moisture evaporated, to remove airborne moisture.
If the amount of moisture of clothing tails off, then heat of gasification reduces, and the temperature of clothing begins to rise once more, if becoming clothing does not have moisture, then reaches with the essentially identical temperature of warm braw and finishes drying (falling rate of drying).The moment that the temperature of entering falling rate of drying clothing begins to rise is that aridity reaches near the moment 0.9.In addition, aridity is with the weight definition of the weight/drying back clothing of drying clothes.The weight of drying clothes is to be that 20 ℃, relative humidity are the weight when in 65% the environment clothing having been placed diel in temperature.
The fundamental formular of the rate of drying of moisture during from material (clothing) surface evaporation is represented with mathematical expression 1.
(mathematical expression 1)
Qs＝α(Ta-Ts)/γ
Wherein: Qs: rate of drying (kg/m
2H)
α: heat transfer coefficient (KJ/m
2H ℃)
γ: evaporation latent heat (KJ/kg)
Ta: the warm braw temperature (℃)
Ts: the evaporating surface temperature (℃)
In addition, if the surface area that clothing is surperficial is made as A (m
2), rate of drying Q then
A(kg/h) be mathematical expression 2.
(mathematical expression 2)
Q
A＝Qs·A＝α·A(Ta-Ts)/γ
Rate of drying when in addition, moisture is from the inner evaporation of clothing is a mathematical expression 3.
(mathematical expression 3)
Qi＝K(Ta-Ts)/γ
Wherein: Qi: rate of drying (kg/m
2H)
K: hot percent of pass (KJ/m
2H ℃)
In addition, hot percent of pass K is with mathematical expression 4 expressions.
(mathematical expression 4)
K＝1/(1/α+L/λ)
L: the thickness of cloth (m)
λ: thermal conductivity (KJ/mhK)
Can know according to mathematical expression 1, mathematical expression 2, mathematical expression 3, mathematical expression 4,, should take following measure in order to accelerate drying (evaporation) speed:
(1) improves warm braw temperature T a.
(2) improve heat transfer coefficient α.
(3) increase surface area A.
(4) improve thermal conductivity λ.
(5) thickness of attenuate cloth.
In case, thereby be advisable it is suppressed to maximum about 90 ℃ because the too high meeting of temperature of warm braw causes the damage to clothing.Therefore, it is difficult accelerating rate of drying through the raising temperature.In addition, because the thermal conductivity of cloth and the thickness of cloth determines by clothing, thereby uncontrollable.Because heat transfer coefficient 0.8 power common and wind speed is proportional, thereby can improve heat transfer coefficient through accelerating wind speed.With regard to the surface area of clothing, if twining, clothing is bulk, then its apparent surface is long-pending reduces.In addition, if be the thick thickening of the then apparent cloth of bulk, rate of drying reduces.Therefore, be advisable to expand clothing as far as possible.
These principles can realize through making the wind speed high speed reach 100m/s.Figure 13 is the photo that the state with the dried clothing of scrubbing-and-drying unit of existing scrubbing-and-drying unit and present embodiment is compared.The dry rated capacity of the scrubbing-and-drying unit that compares is 7kg.Existing scrubbing-and-drying unit is 1.4m with the air quantity
3/ min, wind speed are that 20m/s turns round, and the scrubbing-and-drying unit of present embodiment is 1.65m with the air quantity under the state of having cut out switching valve 54 and suction air valve 55
3/ min, wind speed are that 100m/s turns round.The cloth amount is 3kg, and the clothing that compares is the cotton pyjamas that are easy to generate very much wrinkle.Existing sample is screwed in and is strip together, and surface area reduces, and cloth increases at the thickness on apparent, has hindered the evaporation of moisture and rate of drying reduces.In contrast, the sample of present embodiment is the finished product that clothing launches, wrinkle is few.Why wrinkle is that clothing is extended by blast because when clothing blowed the high wind of wind speed less.Like this, in a single day clothing extends, because surface area just increases, and can not increased by the overlapping apparent thickness that causes of clothing, heat transfer coefficient also can improve, thereby moisture evaporation and rate of drying rises easily, can reduce the dry electric weight that is consumed.
But if the cloth amount increases, because clothing is difficult to activity in washing and dewatering groove 3, because wind generally do not contact with clothing, thereby the drying regime of clothing produces difference with the position of clothing.Figure 14 representes be heater with strong pattern clothing moisture and the clothing variation of temperature when dry.At the first half of drying, because the moisture that contains of clothing is more, the volume of clothing is less, and clothing is movable easily washing and dewatering groove 3 in, thereby warm braw generally contacts with clothing, and the temperature of clothing is unanimity basically.Along with the carrying out of drying, find that moisture reduces clothing and expands.So, the activity of the fore-and-aft direction of clothing in washing and dewatering groove 3 tails off, and the clothing that is positioned at the front side at washing and dewatering groove 3 begins to produce difference with the rate of drying that is positioned at inboard clothing.The clothing of front side is because of dry rapidly with the warm braw excellent contact, and during time entering falling rate of drying early, the temperature of clothing begins to rise.With respect to this, owing to inboard clothing is difficult to contact with warm braw, thereby drying is slower, and the time during the entering falling rate of drying is later, and the time that the temperature of clothing begins to rise also becomes later.Like this; Just produce uneven drying; When making when being positioned at inboard cloth drying and finishing running to suitable aridity (aridity from 1.02 to about 1.04); Inboard clothing temperature is T2 (about 80-90 a ℃), and the clothing of front side is in over-drying state, and its temperature rises to T1 (about 100 ℃) and the essentially identical degree of warm braw.
So, adopt strong mode at dry first half heater 31, close switching valve 54 and suction air valve 55, blow high speed winds from anterior purge port 32.Then, at dry latter half, open switching valve 54 and suction air valve 55, heater 31 adopts weak pattern, and purge port 52 blows warm braw from the rear portion.At dry first half, carry out drying with high rate of drying owing to the effect of high speed winds.Get into during the falling rate of drying along with the carrying out of drying, behind the clothing substantially dry of front side, purge port 52 blows warm braw from the rear portion.Since warm braw with only use the contact with clothing that is difficult to dry inboard from the warm braw of anterior purge port 32, thereby the drying of inboard clothing is promptly carried out.Dry latter half why heater 31 adopt weak pattern to be because; Because the drying at this inboard clothing of moment proceeds to the degree during getting into falling rate of drying; Fuselage is also by heating fully, thereby adopts weak pattern enough for the inboard clothing heater of drying 31.In addition; Because the area of rear portion purge port 52 is bigger than the area of anterior purge port 32; Do not carry out the running of dry latter half if do not change the revolution ground of blowing unit 28,, thereby can further accelerate rate of drying because the wind of comparing with big air quantity with dry first half carries out drying.Have again,, also can reduce the revolution of the blowing unit 28 of dry latter half for the air quantity that makes dry first half and dry latter half is identical.So, owing to can reduce the input power of blowing unit 28, thereby can reduce power consumption.
As stated, owing to can be difficult to the drying of the clothing of dry inboard effectively, thereby can suppress useless power consumption, and can prevent the uneven drying of clothing, prevent that the temperature transition of clothing from rising.
Figure 15 representes is the variations in temperature of the clothing in the drying of present embodiment and the variation of moisture.At dry first half, though identical with the variations in temperature of existing drying machine, can know that at the dry latter half that purge port has been switched to the rear portion, the temperature of inboard clothing rises sharp and be dry.On the other hand, decrease, because of what problem is drying do not have though be in the temperature of the front side clothing that does not have warm braw contact.Like this, because can be at the dry effectively inboard clothing of dry latter half, thereby also can shorten to t2 by the t1 from only with anterior purge port the time drying time, the ability minimizing time also reduced electric power consumption.
In addition, in order further to reduce electric power consumption, also can break off heater 31 at dry latter half.This be because, all very high in the temperature of dry first half clothing and water jacket, washing and dewatering groove 3, and the air themperature in the casing 1 also rises.Suck heated air in the casing 1 at dry latter half if open suction air valve 55, carry out adiabatic compression with blowing unit 28 temperature is further risen.In the occasion of present embodiment, the revolution of blowing unit 28 is 14000 rev/mins, utilizes blowing fan that temperature is risen about 8 ℃.And, because air is obtained heat from water jacket 2 during the rear portion pipeline 51 that fits tightly through the outer peripheral face of being arranged to water jacket 2 temperature is further risen, even thereby also can purge port 52 blow warm braw from the rear portion without heater.Environment temperature is 20 ℃ a occasion around, and the temperature of the warm braw that blows from the rear portion purge port is about 50 ℃ behind the dry latter half of next-door neighbour, though along with the reducing through excess temperature of time, be about 35 ℃ when drying finishes.
Above, though be illustrated from the viewpoint of electric power consumption, the wrinkle aspect of the example of this embodiment when preventing drying also is favourable.That is,, blow from anterior purge port 32 that wind speed is about 100m/s, air quantity is about 1.6m at dry first half
3The warm braw of/min is through launching clothing and when preventing the clothing wrinkle, it is carried out drying with blast.Yet if the amount of clothing is too much, wind at a high speed is difficult to and the contact with clothing that is positioned at the inboard of washing and dewatering groove 3, can not prevent the wrinkling of inboard clothing.In the moment that is transformed into dry latter half, inboard cloth drying arrives the degree during the entering falling rate of drying, and aridity is about 0.9.When aridity surpasses 0.9, to eliminate wrinkle that clothing produced the difficulty that becomes this moment.In the present embodiment, purge port 52 blows warm braw from the rear portion owing to reach moment about 0.9 in the aridity of inboard clothing, thereby has the effect that the wrinkle that makes inboard clothing launches.When the effect of considering to make wrinkle to launch, the wind speed that preferably purge port 52 blows from the rear portion, air quantity and be same degree from the warm braw that anterior purge port 32 blows.But because the rotation of washing and dewatering groove 3, the radial ribbed joint of wind at a high speed and bead 23 touches to produce blows sound of the wind.Therefore, in the present embodiment, make the area of rear portion purge port 52 bigger, wind speed is set at 70m/s, air quantity is set at 1.7m than the area of anterior purge port
3/ min blows sound of the wind with reduction.Even reduce wind speed like this, (10～20m/s) comparison wind speed are still very fast, though slightly descend than the wrinkle expansion effect of anterior purge port, still have enough wrinkles to launch effect with the wind speed that has general scrubbing-and-drying unit now.In addition, though do not blow warm braw at dry latter half to the front side clothing, since dry at the few state of wrinkle, thereby wrinkle does not almost increase in the running of dry latter half.
Yet, in order further to improve drying efficiency, it is also conceivable that to make switching valve 54 be in the neutral position that this two blows warm braw from anterior purge port 32 and rear portion purge port 52 simultaneously.But with regard to the ability of the blowing unit 28 of present embodiment, if will guarantee the wind speed of 100m/s, the air quantity of each purge port is 0.8m
3The degree of/min, with regard to this air quantity, the effect that wrinkle is launched is less, can not obtain the dry mass identical with present embodiment.Be twice if the ability of blowing unit increased; Though blow simultaneously through front and back and can obtain making quality good; But also be multiplied owing to be used for the electric power of blowing unit running,, need reduce the input power of heater for source power supply (100V, 15A); Because the temperature of warm braw reduces, and is not very wise move.In addition, because blowing unit maximizes, having to make the box sizes of scrubbing-and-drying unit to maximize, also is problem from the viewpoint that performance (saving space) is set.But,,,, thereby utilize front and back to blow simultaneously and also can realize the dry and high-quality drying of high efficiency even also can obtain enough heats because the input power of thermal source is little in the occasion of using heat pump mode as the thermal source of warm braw.
In the example of this embodiment, make in the front and back of washing and dewatering groove 3 purge port respectively is set, and air entry is one a structure.This can realize with single blowing unit through the purge port before and after changing with switching valve, thereby can make compactness and scrubbing-and-drying unit cheaply.
In addition, make, form dry (circulation) path of warm braw that the rear portion blows usefulness with open loop, and change the structure of closed loop and open loop with the suction air valve with anterior dry (circulation) path of warm braw that blows usefulness of closed loop formation.In the moment that converts dry latter half from dry first half into, the rear side cloth drying arrives the degree during the entering falling rate of drying, and the moisture of clothing tails off.Therefore, at dry latter half, air with contact with clothing after contained moisture not so much.Therefore, though dry latter half also can be with the water-cooled dehumidifying in drying duct of closed loop state, be the running that weak running of heater or heater break off because dry latter half carries out, thereby because of the lower dehumidification rate of warm braw temperature not too high.So adopting and making dry (circulation) path of warm braw is open loop, in casing, sucks dry air, will contain the structure of discharging from the air of clothing moisture evaporated and can finish drying at short notice.Be released to indoor moisture far fewer than the situation that washings is dried this moment in the room, indoor hardly can be moist.
Below, use Figure 16 and Figure 17 that exhaust is not released to indoor embodiment and describe.Near the connecting portion of drying duct 29 tops and filter pipeline 27, has inlet valve 60.Figure 16 representes inlet valve 60 in detail with the double dot dash line D-D line side cross sectional view of Fig. 4.Inlet valve 60 is by constituting with drive motor 60a, valve body 60b and valve seat 60c.Rotating shaft 60d rotation through make the end of being located at valve body 60b with drive motor makes valve body 60b rotation.Shown in figure 16, will be called with the state of valve body 60b closed valve seat 60c and close the suction air valve; As with shown in the double dot dash line, the state of blocking-up drying duct 29 and filter pipeline 27 is called opens the suction air valve.If make suction air valve 60 be in open mode, then form air entry 61.
Flowing of wind when the structural representation of Figure 17 is represented dry operating.Both close or two types of runnings that both open also to carry out switching valve 54 and inlet valve in the present embodiment.The situation of opening for both (solid arrow of Figure 17) is omitted its explanation owing to identical with above-mentioned embodiment example, and situation about only both being opened (dotted arrow of Figure 17) describes.If running blowing unit 28, then the air in the casing 1 is from air entry 56 filter by suction pipelines 27 interior (dotted arrow 46).Then; Get into aspirating air pipe 33 and be inhaled into (arrow 44) in the blowing unit; Get into rear portion pipeline 51 (dotted arrows 47) from corrugated pipe connector 30b, pipeline is directed into the back side of water jacket 2 at the rear portion, and purge port 52 is blown in the washing and dewatering groove 3 (dotted arrow 48) from the rear side of washing and dewatering groove 3 from the rear portion; Inboard contact with clothing with in the washing and dewatering groove 3 makes moisture evaporate from clothing.Then, air flows into water jacket 2 from the through hole that is arranged on the washing and dewatering groove 3, and a part is discharged outside machine from scupper hose 26 through overflow hose 2f (dotted arrow 49) from overfall 2e.Remainder is discharged outside machine through draining valve 25 (dotted arrow 50) and from the air-flow interflow of overflow hose 2f and from scupper hose 26 from water discharge outlet 2b.Usually, because scupper hose is connected with sparge pipe, it is interior and be not discharged to indoorly that air is discharged to sparge pipe, thereby can prevent the increase of indoor moisture.
Though the example of aforesaid embodiment constitutes dry (circulation) path of warm braw that the front portion blows usefulness by closed loop, constitute dry (circulation) path of warm braw that the rear portion blows usefulness by open loop, adopt opposite formation also can obtain identical effect.The air of this situation flow (structure is identical with situation shown in Figure 12) in the structural representation be illustrated in Figure 18.Operating as as follows of this situation circulates, and purge port 52 blows warm braw to dry first half from the rear portion, and dry latter half blows warm braw from anterior purge port 32.Purge port 52 blows the occasion of warm braw from the rear portion, closes inlet valve 55 if open switching valve 54, then air such flowing shown in the dotted arrow among the figure.If running blowing unit 28; To heater 31 energisings; Then get into rear portion pipeline 51 (dotted arrows 47) from corrugated pipe connector 30b, pipeline is directed into the back side of water jacket 2 at the rear portion, and purge port 52 is blown in the washing and dewatering groove 3 (dotted arrow 48) from the rear side of washing and dewatering groove 3 from the rear portion; Inboard contact with clothing with in the washing and dewatering groove 3 makes moisture evaporate from clothing.How wet air flows into water jacket 2 from the through hole that is arranged on the washing and dewatering groove 3 to become high temperature, is inhaled in the drying duct 29 from air entry 2a, and (dotted arrow 62) from bottom to top flows in drying duct 29.Utilization is arranged at the water-cooled desiccant body cooling and dehumidifying in the drying duct 29 and becomes dry Cryogenic air and get into filter tube road 27 (dotted arrow 67).Enter into aspirating air pipe 33 through being arranged at after filter pipeline 27 interior gauze filter 8a remove the line bits again, sucked, heat once more, be blown in the washing and dewatering groove 3 by heater 31 by blowing unit 28.
Close switching valve 54 and open inlet valve 55 from the occasion that anterior purge port 32 blows warm braw.If running blowing unit 28, then the air in the casing 1 is inhaled in the filter pipeline 27 (arrow 65) from air entry 56.Then, enter in the washing and dewatering groove 3 (arrow 41) from anterior purge port 32 through filter 8, blowing unit 28, heater 31.Front side contact with clothing with in the washing and dewatering groove 3 makes moisture evaporate from clothing.Then, flow into water jacket, be pressed in the drying duct 29 (arrow 42) from air entry 2a from the through hole that is arranged on the washing and dewatering groove 3.In drying duct 29, flow from bottom to top and enter into discharge duct 58, remove line bits back by filter 59 and outside machine, discharge (arrow 64) from exhaust outlet 7.
More than, according to present embodiment, through converting dry (circulation) path of warm braw that forms first half by closed loop to, form warm braw drying (circulation) path of latter half by open loop, the discharge of air outside machine can be suppressed, and power consumption can be reduced with moisture.In addition, owing to when changing, change the blowing direction of warm braw with dry path, thereby, can make warm braw from direction and the contact with clothing different with dry first half, can also suppress uneven drying.
In addition, owing in dry operating, warm braw at a high speed directly is blown on the clothing, thereby the raising of the heat transfer coefficient of clothing and wind, warm braw is heats laundry effectively.In addition, because wind speed is high, the easy contact with clothing inner of wind with being in swing roller.
Have, purge port is blown into wind from the back owing to the latter half in drying, thereby has promoted to be in the drying of the inboard clothing of swing roller, can prevent uneven drying, and can realize the shortening of drying time and the minimizing of consumes electric power again.
In addition, the temperature of dry latter half clothing fully rises, and in that purge port is blown into the occasion of wind from the back, can reduce power consumption through heating arrangements being carried out weak running.Perhaps, through stopping the energising of heating arrangements, suck at the air of the heated box house of dry first half from air-breathing position and be blown on the clothing, owing to do not use heating arrangements can supply with warm braw yet, thereby can further reduce power consumption.
In addition, purge port is blown into the occasion of warm braw from the back at dry latter half, owing to suck the air of the drying in the casing, and the wet air in the swing roller is discharged outside casing, thereby moisture can more effectively reduce power consumption more effectively from removing.So, owing to can prevent temperature rising because of the over-drying clothing that causes of clothing, thereby can also suppress damage to clothing.
And,, thereby can be reduced in from the back sound of the wind of blowing that is produced when the wind that blows of purge port contacts with the base plate of swing roller because the wind speed of back purge port is lower than the wind speed of preceding purge port.
Have again; Since with the position of suction inlet and purge port relation be arranged to the centre across the rotating shaft of swing roller and away from the position; Thereby can prevent that the wind that purge port blows from the back from not sucking from suction inlet with contact with clothing, can the inboard clothing of dry effectively swing roller.
