As shown in Figure 3, the wind path switching part 12 that is arranged on the branching portion between first wind path 9 and second wind path 11 comprises shield 21, reduction gearing 22, drives the CD-ROM drive motor 23 and the rib 28 of shield 21.

Shield 21 optionally covers one of them of first wind path 9 and second wind path 11.Fig. 3 illustrates the shield 21 that covers second wind path 11.Its result, dry air circulates through first wind path 9.Fig. 4 illustrates the shield 21 that covers first wind path 9.Its result, dry air circulates through second wind path 11.

As shown in Figure 5, shield 21 comprises: the rotation axial region 21a that is installed in the branching portion between first wind path 9 and second wind path 11; Be arranged on the gear installation portion 21b of the upper end of rotating axial region 21a; And be fixed on the shielding portion 21c that rotates on the axial region 21a.Shielding portion 21c optionally covers one of them of first wind path 9 and second wind path 11.In this embodiment, shielding portion 21c is as curtain-shaped cover member and by illustration.

Shield 21 for example uses material formation such as synthetic resin.The shielding portion 21c of shield 21 has upper limb 21x, lower edge 21y and front-end edge 21z.The size of upper limb 21x, lower edge 21y and front-end edge 21z and profile are set according to the section shape of the branching portion of guiding wind path 24.

The area of the shielding portion 21c of shield 21 is greater than the sectional area of second wind path 11 that is connected branching portion.As shown in Figure 3, the shielding portion 21c that is arranged on the position vertical with second wind path 11 covers second wind path 11 fully.

The shielding portion 21c of shield 21 forms to such an extent that be slightly less than the section of first wind path 9, so that rotate in the branching portion in being formed on guiding wind path 24.Between the inner face of the upper limb 21x of shielding portion 21c and the lower edge 21y and first wind path 9, be formed with the space.The design in the too narrow space between the inner face of upper limb 21x and lower edge 21y and first wind path 9 not only needs too high installation accuracy, also brings out foreign matter easily and embeds this space.Therefore, the space between the inner face of the upper limb 21x of shielding portion 21c and lower edge 21y and first wind path 9 can be set to about 1.5mm.

Like Fig. 3, Fig. 6 and shown in Figure 7, on the inner face of first wind path 9, be formed with rib 28.Ora terminalis (upper limb 21x, lower edge 21y and the front-end edge 21z) butt of the shielding portion 21c of rib 28 and shield 21.Rib 28 is formed on along the downstream of the shielding portion 21c of the flow direction shield 21 of dry air.As shown in Figure 4, when covering first wind path 9 when shield 21 rotations, the ora terminalis of shielding portion 21c (upper limb 21x, lower edge 21y and front-end edge 21z) is connected to rib 28.Its result, first wind path, 9 21c of crested portion and rib 28 complete closed.

Fig. 8 diagrammatically illustrates the butt of shield 21 and rib 28.In addition, Fig. 8 diagrammatically illustrates along the section of A-A line shown in Figure 4.With reference to Fig. 4 and Fig. 8 the butt of shield 21 with rib 28 described.

The overhang of excessive rib 28 (from the overhang of first wind path, 9 inner faces) can cause bigger air drag.Therefore, the overhang that comparatively it is desirable to rib 28 is set at for example about 2mm.If the space between the inner face of the ora terminalis of the shielding portion 21c of shield 21 (upper limb 21x, lower edge 21y and front-end edge 21z) and first wind path 9 is set at about 1.5mm, then the rib 28 of the overhang of about 2mm is about 0.5mm with the lap of shielding portion 21c.The lap of about 0.5mm is enough to seal first wind path 9.In addition, the space between the inner face of the overhang of above-mentioned rib 28, shield 21 and first wind path 9 and the value of lap are an example, also can these dimensional parameters be set at other values.

Angle θ shown in Figure 4 is meant that shield 21 goes to the angle of rotation (perhaps, being connected to shielding portion 21c and the bearing of trend angulation of first wind path 9 of the shield 21 of rib 28) of the hidden position of first wind path 9 from the hidden position of second wind path 11.In this embodiment, angle θ is set to about 50 degree.When angle θ is set at the angle (in this embodiment for about 50 degree) less than 90 degree, to the dry air that second wind path 11 from first wind path, 9 branches flows smaller with the caused pressure loss of collision of the shielding portion 21c of shield 21 (being set at 90 with angle θ compares when spending).Therefore, form to second wind path 11 stream of crooked dry air gently.Thereby dry air flows into second wind path 11 efficiently.

In this embodiment, angle θ is set to greater than the angle of 45 degree (being about 50 degree in this embodiment).Therefore because angle θ is set at the value greater than 45 degree, is set at 45 to the sectional area of the stream of the crooked dry air of second wind path 11 and angle θ and compares greatly when spending.In this embodiment, consider the pressure loss of the corner part on the branching portion that is formed between first wind path 9 and second wind path 11 and the stream sectional area of dry air, angle θ is set in 50 degree to the scope of 55 degree comparatively desirable.

Be arranged on the shielding portion 21c almost parallel of rib 28 and shield 21 in the downstream of the shield 21 that covers first wind path 9.The periphery of the shielding portion 21c of shield 21 (upper limb 21x, lower edge 21y and front-end edge 21z) is at the hidden position of first wind path 9 and rib 28 butt closely.In the butt zone of the shielding portion 21c of shield 21 and rib 28, comparatively it is desirable to be provided with packaged units such as O shape ring.Packaged unit reduces from the shielding portion 21c of shield 21 and the leakage of the air between the rib 28.Packaged units such as O shape ring can be arranged on one of them of shielding portion 21c and rib 28 of shield 21.

Fig. 9 is the approximate three-dimensional map of guiding wind path 24.With reference to Fig. 3 to Fig. 6 and Fig. 9 the installation of shield 21 is described.

The rotatable earth's axis in an end that is arranged on the rotation axial region 21a of the inner shield 21 of first wind path 9 is supported in the guiding wind path 24.Another distolateral perforation of rotation axial region 21a is located in the installing hole 24a (with reference to Fig. 6 and Fig. 9) on the guiding wind path 24 and is supported by axle rotationally.Connecting installing hole 24a and be provided with gear installation portion 21b (with reference to Fig. 5) to the end of first wind path, the 9 outside rotation axial region 21a that give prominence to.On gear installation portion 21b, like Fig. 3 and the second gear 22b that reduction gearing 22 is installed shown in Figure 4.

Reduction gearing 22 from the driving force of CD-ROM drive motor 23 to shielding portion 21c that transmit comprises first gear 22a (columnar spur gear) and the second gear 22b (cutting into fan-shaped spur gear) that meshes with the first gear 22a.The diameter of the first gear 22a is less than the second gear 22b.The first gear 22a is used as pinion (small-diameter gear).The first gear 22a is installed on the motor axis of rotation 23a of CD-ROM drive motor 23.The rotary power of CD-ROM drive motor 23 directly is transferred to the first gear 22a.In addition, also can realize with direct mode from the power transmission of CD-ROM drive motor 23, and utilize other power transmission mechanism to realize unlike above-mentioned that kind to the first gear 22a.

Along with the rotation of the first gear 22a, with the second gear 22b rotation of first gear 22a engagement.Therefore, the first gear 22a uses as driven wheel, and the second gear 22b uses as driven gear.

In following explanation, the number of teeth of the first gear 22a (driven wheel) is labeled as " Z1 ".And, the number of teeth of the second gear 22b (driven gear) is labeled as " Z2 ".The speed reducing ratio of reduction gearing 22 is expressed as Z2/Z1.

In following explanation, the rotating speed of the first gear 22a (driven wheel) is labeled as " N1 ".And, the rotating speed of the second gear 22b (driven gear) is labeled as " N2 ".The speed reducing ratio of reduction gearing 22 is expressed as N1/N2.Recently adjust the driving torque that is installed in the shield 21 on the second gear 22b according to the deceleration of reduction gearing 22.

As stated, utilize the CD-ROM drive motor 23 and the combination of reduction gearing 22 can obtain the driving torque of enough big shield 21.For example, comparatively it is desirable to, set the driving torque of shield 21, so that the pinning of the shield 21 that can not take place to cause because of the foreign matter that is clipped between the shield 21 and first wind path 9.

Figure 10 is the branching portion summary amplification stereogram on every side of first wind path 9 and second wind path 11.With reference to Fig. 2 to Fig. 4 and Figure 10 the driving of shield 21 is described.

Shown in figure 10, the

22a and 29 coverings of the second gear 22b tegmentum parts.Cover 29 inhibition foreign matters are sneaked into engaging piece and the external foreign matter of the first gear 22a and the second gear 22b and are sneaked in first wind path 9.

In this embodiment, the stepper motor that use can two-way rotation is as CD-ROM drive motor 23.Apply driving pulse in conjunction with the illustrated 70 pairs of CD-ROM drive motors 23 of control part of Fig. 2 and adjust the rotation amount of CD-ROM drive motor 23 (anglec of rotation).Its result, the action of shield 21 is suitably controlled.

As shown in Figure 3, when the hidden position to second wind path 11 drove

shield

21,70 pairs of CD-ROM drive motors 23 of control part applied the driving pulse of unnecessary umber of pulse so that produce some transfiniting (overrun).Its result when shield 21 is connected to the peripheral wall surface of second wind path 11, applies the pressure of appointment to shield 21.Therefore, shield 21 can suitably cover second wind path 11.

As shown in Figure 3, be formed with restriction rib 30 in the outside of guiding wind path 24.The right part 22c that restriction rib 30 is connected to the second fan-shaped gear 22b is to limit the second gear 22b rotation of direction left.Therefore, shield 21 direction inordinate rotation left hardly.

Equally, as shown in Figure 4, when the hidden position to first wind path 9 drove

shield

21,70 pairs of CD-ROM drive motors 23 of control part applied the driving pulse of unnecessary umber of pulse so that produce some transfiniting.Its result when shield 21 is connected to rib 28, applies the pressure of appointment to shield 21.Therefore, shield 21 can suitably cover first wind path 9.

As shown in Figure 4, be formed with restriction rib 31 in the outside of guiding wind path 24.The left part 22d that restriction rib 31 is connected to the second fan-shaped gear 22b is to limit the second gear 22b rotation of direction to the right.Therefore, shield 21 direction inordinate rotation to the right

hardly.Restriction rib

30,31 forms through the corner top that depression is provided with the branching portion of first wind path 9 and second wind path 11.

(action of scrubbing-and-drying unit)

Action and advantageous effects to above-mentioned drum-type washing drying machine 500 describe.

Above-mentioned scrubbing-and-drying unit 500 reduces the fold of the clothing that during drying process, is produced.

In narrow cylinder, clothing is dried under the state of full extension not.Therefore, generally, the clothing that in narrow cylinder, is dried can produce more fold.Can let the user feel dissatisfied like this.Especially, contain cotton more clothing and can produce more fold.Therefore, if cotton amount increases then the easy variation of dried outward appearance.

When in cotton fiber, moisture being arranged, cotton fiber can more freely move each other.Therefore, even if the clothing that is stirred along with the rotation of cylinder because of the mechanical force bending, if apply the power to the directive effect that stretches clothing afterwards, then can be stretched by the part of bending, thereby eliminate fold.

Along with the carrying out of drying process, the moisture in the cotton fiber reduces, thereby cotton fiber adhesion each other strengthens.Its result, cotton fiber is difficult to move.If mechanical force makes the cotton fiber bending in the few cotton fiber of moisture, then cotton fiber is kept the bending state easily.

Along with further carrying out of drying process, the moisture in the cotton fiber further reduces.Thereafter, even if apply the power to the directive effect that stretches cotton fiber, cotton fiber is also kept the bending state and is stretched hardly.This state is called " set of fold (wrinkle fixation) ".

Therefore, though be used for the evaporation that the drying process of drying clothes impels clothing moisture, also can bring because of moisture and reduce caused clothing fold.The fold set is many more, and dried outward appearance is poor more.

The bending of fiber is inevitable in narrow cylinder.Therefore, in order to alleviate fold, need to reduce the fold number of the clothing that in cylinder, produces and the rapid bending (the bending angle of acute angle) of the fiber that minimizing causes the firm set of fold.Stretched like quilt after the bending part of fruit fiber, and the fiber at other positions then also can be reduced the fold of clothing by bending in narrow cylinder.During drying process, the bending part that comparatively it is desirable to fiber changes continually.If along with the carrying out of drying process the moisture in the fiber is reduced,, also can suppress the generation of new fold because of interfibrous stronger adhesion even if the power of the fiber bending of having been stretched is had an effect.

Through above research, the generation easness of fold changes along with the drying regime of clothing.Clothing (being easy to generate the clothing of fold most) to be processed by cotton fiber is that benchmark describes the index of aridity that is easy to generate fold.

The easiest set of fold in the scope of the index of aridity about 85% to about 100%.Especially, if the index of aridity of the clothing of being processed by cotton fiber is in about 90% to about 100% scope, then set the most easily of the fold of clothing.In addition, following numerical expression is represented the index of aridity (%).

The index of aridity (%)=(the clothing quality of standard/contain the clothing quality of moisture) * 100 (numerical expressions 1)

At this, " the clothing quality of standard " is meant clothing quality balanced under the condition of 20 ℃ of temperature and humidity 65%.

In conjunction with the uneven drying of a clothing, the fold of clothing is described.

A clothing also can produce uneven drying.Clothing is also anisotropically dry, can produce dry slower zone.For example, the drying of the oxter part of long-sleeved blouse is the slowest.

Usually, because above-mentioned uneven drying, the desired value of the index of aridity when therefore drying being finished is set at and surpasses 100% the value (index of aridity for example: 102% to 105%).If clothing is dry by equably under these desired values, then clothing is over-drying.

In following explanation, will be called " initial arid region " to the scope of about 90% the index of aridity from the back of just dewatering.In initial arid region, the fold of clothing is difficult for set as stated.About 90% scope to about 100% index of aridity is called " middle arid region ".In middle arid region, relatively be easy to generate the set of fold.To be called " later stage arid region " above the scope of 100% the index of aridity.In the later stage arid region, the fold of clothing is difficult for set as stated.

In this embodiment, during middle arid region, see high pressure and dry air at a high speed off from second blow-off outlet 10 of second wind path 11.High pressure and the dry air at a high speed seen off from second blow-off outlet 10 of second wind path 11 significantly launch clothing, thereby reduce the fold of clothing effectively.Initial arid region and later stage arid region at least one of them during, from the bigger dry air of first blow-off outlet, 8 supply flows of first wind path 9.Feed lines through in drying process, between first wind path 9 and second wind path 11, switching dry air realizes province's electrification.

As stated, to during the drying process and " initial arid region ", " the middle arid region " set reach " later stage arid region ", can infer based on elapsed time from drying process zero hour.In this embodiment, control part 70 is based on judging that from the elapsed time of drying process zero hour drying process belongs to " initial arid region ", " middle arid region " and reaches " later stage arid region " which.Control part 70 is controlled wind path switching part 12 based on judged result, between first wind path 9 and second wind path 11, switches the path of dry air.

For example, control part 70 store in advance to drying process the term of execution and set first set during.If from elapsed time that drying process begins surpass first set during, then control part 70 judges that drying processes are in initial arid region.Control part 70 store in advance to drying process the term of execution and set second set during.In addition, be set to greater than the value during first setting during second setting.In the scope during setting to second during if the elapsed time of drying process is in and sets from first, then control part 70 is judged the drying processes arid region that mediates.If the elapsed time of drying process surpasses during second setting, then control part 70 judges that drying processes are in the later stage arid region.

During drying process, control part 70 suitably switches dry air based on above-mentioned judged result between first wind path 9 and second wind path 11 path.Its result, single air supplying part 4 capable of using and reduce the fold of clothing effectively.

As stated, initial arid region and later stage arid region at least one of them during, from the bigger dry air of first blow-off outlet, 8 supply flows of first wind path 9.From the bigger dry air of first blow-off outlet, 8 supply flows, with to compare consumes electric power from second blow-off outlet 10 supply high speed dry airs few.Therefore; The scrubbing-and-drying unit 500 of this embodiment with high pressure and supply the device of dry air at high speed or have be used for except that the supply high pressure and the dry air at a high speed also the device of a plurality of fans of appending property ground increase air quantity compare, can realize less total power consumption.Thereby the drum-type washing drying machine 500 of this embodiment can make clothing produce fold ground hardly with less power consumption and realize good drying effect.

The sequential chart on Figure 11 opportunity that to be illustration switch the path of dry air.Referring to figs. 1 through Fig. 5 and Figure 11 the switching to the path of dry air is described.

Beginning in cylinder 1, to supply dry air from first wind path 9 to through the initial arid region till first setting-up time from drying process.Because first wind path 9 is used to supply the sectional area of the mobile stream of dry air bigger, so the pressure loss of dry air is less.The dry air of the big flow of supplying through first wind path 9 blows out and and contact with clothing from first blow-off outlet 8 that is formed on tank 2 bottoms.The CD-ROM drive motor 23 of control part 70 control wind path switching parts 12, the shielding portion 21c with shield 21 as shown in Figure 3 seals second wind path 11.Its result, first wind path 9 is opened.Then, the drying process that hops to it.When hopping to it drying process, control part 70 utilizes timer 71 to measure from the elapsed time of the zero hour of drying process.Control part 70 makes first wind path 9 continue to open till the elapsed time from zero hour of drying process surpasses first setting-up time.Because the pressure loss of the dry air through first wind path 9 is smaller, so control part 70 gets the speed setting of fan motor 4b smaller.Air supplying part 4 can be less power consumption in cylinder 1, supply the dry air of big flow.The dry air of big flow is supplied in the cylinder 1, shortens between the dry period of therefore initial arid region.In addition, the electric weight that in initial arid region, consumes also is reduced.

When the elapsed time from zero hour of drying process has surpassed first setting-up time, control part 70 judge drying processes get in the middle of the arid region.The CD-ROM drive motor 23 of control part 70 control wind path switching parts 12 switches to second wind path 11 with the path with dry air.In addition, control part 70 increases the rotating speed of fan motor 4b.Its result, dry air flows in the cylinder 1 from second blow-off outlet 10 in middle arid region.Supply the sectional area of the mobile stream of dry air less because second blow-off outlet 10 is compared with first blow-off outlet 8, the dry air that therefore blows out from second blow-off outlet 10 is high pressure and dry air at a high speed.

When the elapsed time from zero hour of drying process surpasses first setting-up time, the CD-ROM drive motor 23 of control part 70 control wind path switching parts 12, the shielding portion 21c of shield 21 that makes as shown in Figure 4 is connected to rib 28.Its result opens second wind path 11 in sealing first wind path 9.Then, control part 70 control air supplying part 4 are to improve the rotating speed of fan motor 4b.Control part 70 makes second wind path 11 continue to open till the elapsed time from zero hour of drying process surpasses second setting-up time.In middle arid region, because high pressure and dry air at a high speed launch clothing, so the fold of clothing reduces.

When the elapsed time from zero hour of drying process surpassed second setting-up time, control part 70 judged that drying processes get into the later stage arid regions.The CD-ROM drive motor 23 of control part 70 control wind path switching parts 12 switches to first wind path 9 once more with the path with dry air.

As stated, in the later stage arid region, clothing contains fewer moisture.Less contact with moisture in dry air and the clothing needs that chien shih moisture evaporates from clothing when long.Therefore, the dry air of the big flow of supply is suitable for increasing moisture and the touch opportunity of dry air in the clothing in cylinder 1.In addition, because dry air is supplied in the cylinder 1 through first wind path 9, power consumption that therefore can be lower realizes the ratio higher flows of dry air.

In the later stage arid region, first wind path 9 is as the circulating path of dry air and utilize.First wind path 9 supplies the sectional area of the mobile stream of dry air bigger, so the pressure loss of dry air is smaller.The dry air of big flow blows out and and contact with clothing from first blow-off outlet 8 that is formed on tank 2 bottoms.

When the elapsed time from zero hour of drying process surpasses second setting-up time, the CD-ROM drive motor 23 of control part 70 control wind path switching parts 12, first wind path 9 of opening as shown in Figure 3.In addition, control part 70 control air supplying part 4 reduce the rotating speed of fan motor 4b.Afterwards, control part 70 makes first wind path 9 continue to open till drying process finishes.Because the pressure loss of the dry air through first wind path 9 is less, so control part 70 must be lower with the speed setting of fan motor 4b.Like this, available less power drive air supplying part 4.In addition, air supplying part 4 can realize the bigger flow of dry air.Therefore, shorten between the dry period of later stage arid region.In addition, the electric weight that in the later stage arid region, consumes also is reduced.

In this embodiment, control part 70 is based on judging that from the elapsed time (first setting-up time and second setting-up time) of zero hour of drying process " initial arid region ", " middle arid region " the drying process reach " later stage arid region ".Yet, during the whole drying process and " initial arid region ", " middle arid region " reach " later stage arid region " separately during can change according to being housed in cylinder 1 interior laundry amounts.Therefore; Comparatively it is desirable to, control part 70 is used for judging that based on the testing result adjustment of the test section that detects the laundry amounts in the cylinder 1 " initial arid region ", " middle arid region " reach first setting-up time and second setting-up time of " later stage arid region ".

Test section 15 can detect the laundry amounts (quality) that drops in the cylinder 1 before the beginning washing procedure.For example; Test section 15 detects the position and difference in spools 141 position of the damper 14 when putting in the cylinder 1 of (before in tank 2, supplying water) and clothing before the beginning washing procedure of the axle 141 of the damper 14 that supports empty tank 2 (supply water to tank 2 in, and to cylinder 1 in, drop into clothing).About the information conduct of axle 141 position difference is exported to control part 70 with the relevant information of laundry amounts that drops into cylinder 1.Like this, control part 70 can be judged the laundry amounts in the cylinder 1 based on the position difference of axle 141.

The laundry amounts that drops in the cylinder 1 is many more, and control part 70 is set first setting-up time and second setting-up time long more based on the testing result of test section 15.Its result, can suitably set according to the laundry amounts in the cylinder 1 " initial arid region ", " middle arid region " reach " later stage arid region " during.Control part can switch the circulating path of dry air based on during first setting of suitably setting according to cylinder 1 clothing amount and during second setting between first wind path 9 and second wind path 11.

Action to wind path switching part 12 describes.

70 pairs of CD-ROM drive motors 23 of control part apply driving pulse.CD-ROM drive motor 23 is to the direction rotation corresponding with the driving pulse that applies.The driving force of CD-ROM drive motor 23 is transferred to the first gear 22a that is installed on the motor axis of rotation 23a.Then, the driving force of CD-ROM drive motor 23 is transferred to the second gear 22b that meshes with the first gear 22a.

The reduction gearing 22 that comprises the first gear 22a and the second gear 22b is slowed down with the speed reducing ratio of the appointment rotating speed to CD-ROM drive motor.Its result is used to drive the torque increase of shield 21.Be installed in shield 21 on the second gear 22b with the two-way rotation of enough torques.Therefore, can be because of the pinning of the shield that foreign matter caused 21 between the inner face that is clipped in the shield 21 and first wind path 9 through set to such an extent that be able to suppress according to the speed reducing ratio of reduction gearing 22 than higher torque.Therefore, shield 21 suitably rotates.Under the suitable speed reducing ratio of reduction gearing 22, can produce the situation of the position of uncontrollable shield 21 hardly.

Scrubbing-and-drying unit in the past can produce unfavorable condition because of foreign matter to the switching controls of the circulating path of dry air.For example, can't select desired circulating path, perhaps produce air and leak.As stated, the scrubbing-and-drying unit 500 of this embodiment is not because bigger torque in shield 21, therefore is subject to the influence of foreign matter.Therefore, the difficult generation above-mentioned unfavorable condition that scrubbing-and-drying unit comprised in the past.

Therefore, the scrubbing-and-drying unit 500 of this embodiment is not subject to foreign matter influence, can produce the unfavorable conditions such as pinning or air leakage of shield 21 hardly.Therefore, the reliability that the scrubbing-and-drying unit 500 of this embodiment can be higher is switched the circulating path of dry air.The scrubbing-and-drying unit 500 of this embodiment has the structure of the high reliability of the circulating path that is used to switch dry air, so scrubbing-and-drying unit 500 can be kept higher drying property for a long time.

As shown in Figure 4, the periphery (upper limb 21x, lower edge 21y and front-end edge 21z) of shielding portion 21c that turns to the shield 21 of the position of covering first wind path 9 is connected to rib 28, thereby first wind path 9 is suitably covered.Therefore, be difficult to from first wind path, 9 leadage airs.Thereby, can realize the high and circulation of dry air efficiently of reliability.

On the loop direction of dry air, rib 28 is set at the downstream of shield 21.Therefore, shield 21 is by the pressure of the dry air that contacts with shield 21 and press to rib 28.Thereby shield 21 fits in rib 28 easily.Its result is difficult between shield 21 and rib 28, flow out air.Therefore, rib 28 have concurrently be used for shield 21 be fixed on assigned address block function and with the closing function of shield 21 cooperation sealing first wind path 9.

As shown in Figure 4, the angle θ that covers between the bearing of trend of shield 21 and first wind path 9 of first wind path 9 is set at 50 degree to the scope of 55 degree.Its result, the pressure loss of the dry air of the bend through the branching portion between first wind path 9 and second wind path 11 is suitably reduced.In addition, the sectional area of the stream of the dry air of the bend of branching portion is kept suitable size.Therefore, dry air can flow into second wind path 11 from first wind path, 9 branches through gently crooked circulating path.

Figure 12 is the approximate three-dimensional map of the internal structure of expression guiding wind path 24.Figure 13 is the amplification stereogram around the rib 28 of guiding wind path 24 shown in Figure 12.With reference to Fig. 3, Fig. 4, Fig. 8, Figure 12 and Figure 13 rib 28 is described.

Fig. 3, Fig. 4 and rib 28 shown in Figure 8 form the roughly outstanding profile of C font.Its result, upper limb 21x, lower edge 21y and the front-end edge 21z butt of the shielding portion 21c of rib 28 and shield 21.Replace,, also can omit the part of rib 28 and front-end edge 21z butt like Figure 12 and shown in Figure 13.For example, when shield 21 is in the position of covering first wind path 9, be in from the front-end edge 21z of the turning cylinder position farthest of shield 21 can with the sidewall butt of guiding wind path 24.Its result even if rib 28 does not have the part corresponding with front-end edge 21z, also can suitably be covered first wind path 9.

Like Figure 12 and shown in Figure 13, comparatively it is desirable to, guiding wind path 24 comprises from the inwardly outstanding outstanding wall 61 of the sidewall of guiding wind path 24.Outstanding wall 61 is positioned at the upper reaches of covering the shield 21 of first wind path 9 on the loop direction of dry air.Outstanding wall 61 on the sidewall of front-end edge 21z institute butt through being formed on shield 21 or adjacent guiding wind path 24 suppresses dry air at the front-end edge 21z of shield 21 and guide between the wind path 24 and pass through.In this embodiment, outstanding wall 61 is as protuberance and by illustration.In addition, the side wall surface that is formed with outstanding wall 61 is as inner face and by illustration.

If be formed with outstanding wall 61, the front-end edge 21z that then can not be used in shield 21 installs seal members such as sealing gasket.Even if between the sidewall of the front-end edge 21z of shield 21 and guiding wind path 24, have slight void, also because the outstanding wall 61 at the upper reaches that in the circulating path of dry air, are formed on shield 21 contacts the slight void that makes between the sidewall that dry air is difficult to flow into the front-end edge 21z of shield 21 and guide wind path 24 with mobile dry air.Therefore, outstanding wall 61 suitably reduces through the front-end edge 21z of shield 21 and the air leakage of the slight void between guiding wind path 24 sidewalls.

Outstanding wall 61 forms not hinder shield 21 rotationally.Owing between front-end edge 21z and outstanding wall 61, be provided with slight gap, the front-end edge 21z of the shield 21 in therefore rotating can not contact with outstanding wall 61.

Figure 14 is the approximate three-dimensional map of the internal structure of expression guiding wind path 24.Figure 15 is the amplification stereogram around the rib 28 of guiding wind path 24 shown in Figure 14.With Figure 14 and Figure 15 rib 28 is described.

Guiding wind path 24 also can comprise inwardly outstanding jump (jump) platform 62 of sidewall that is connected from second wind path 11.Ramp 62 is formed on the upper reaches of the front-end edge 21z of the shield 21 that covers second wind path 11 on the loop direction of dry air.In addition, ramp 62 is adjacent with the front-end edge 21z of the shield 21 that covers second wind path 11.The dry air of circulation is guided and the front-end edge 21z of the shield 21 of jumping over by the inclined plane of ramp 62.In this embodiment, ramp 62 is as protuberance and by illustration.In addition, the side wall surface that is formed with ramp 62 is as inner face and by illustration.

Set greater than the thickness of the front-end edge 21z of the shielding portion 21c of shield 21 from the outstanding overhang of guiding wind path 24 inner faces ramp 62.For example, if the thickness of the front-end edge 21z of shielding portion 21c is about 2mm, for example then can the overhang of ramp 62 be set at about 2.5mm to about 3mm.Ramp 62 makes dry air be difficult to flow into the front-end edge 21z of shield 21 and guide between the sidewall of wind path 24.

Cover face and the flow direction almost parallel of dry air of shielding portion 21c of the shield 21 of second wind path 11.Though second wind path 11 is blocked by the shielding portion 21c of shield 21, under the situation that does not have ramp 62, the dry air of circulation also can flow into the front-end edge 21z of shield 21 sometimes and guide between the sidewall of wind path 24.Dry air also can cause sometimes that to the front-end edge 21z of shield 21 and the inflow between guiding wind path 24 sidewalls shield 21 leaves the sidewall of guiding wind path 24.Its result, under the situation that does not have ramp 62, the dry air of circulation might flow into second wind path 11.

If be formed with ramp 62, then since dry air can be through on the loop direction of dry air, being formed on shield 21 the ramp 62 at the upper reaches, so dry air can be crossed the front-end edge 21z of shield 21.Therefore, dry air is difficult to directly contact with the front-end edge 21z of shield 21.Its result, the dry air of circulation can get into the front-end edge 21z of shield 21 hardly and guide between the sidewall of wind path 24.Like this, be difficult to take place of the inflow of unwanted dry air to second wind path 11.

Ramp 62 is formed on the upper reaches of the front-end edge 21z of shield 21 on the loop direction of dry air.Because ramp 62 can not disturb the rotation of shield 21, front-end edge 21z and the interval between the ramp 62 of therefore sealing the shield 21 of second wind path 11 can be set to such an extent that be narrower than the interval of the front-end edge 21z and the outstanding wall 61 of shield 21.
