In Fig. 8 of Fig. 5 of the first embodiment and the second embodiment, illustrate the primary importance P1 that switching valve 36 is got to the rotation of arrow 40A direction, around switching valve 36 or the part that contacts with switching valve 36 of the inner peripheral surface of warm braw inlet portion 41 be provided with such as the seal that is consisted of by flexible member may such as rubber (not shown), in order to will seal between switching valve 36 and warm braw inlet portion 41, thereby will be held in airtight construction between the inner peripheral surface of warm braw inlet portion 41 and switching valve 36.
Thus, shown in Figure 8 as Fig. 5 of the first embodiment and the second embodiment, pass through blast pipe 25 (with reference to Fig. 3) warm braw 50A and only be directed to the first blast channel 39A that is separated by switching valve 36 and demarcation strip 38 at warm braw inlet portion 41, then be blown out to cylinder 5 inside from the first blow-off outlet 37A (37C).On the other hand, the the second blast channel 39B that is connected with the second blow-off outlet 37B is by switching valve 36 and demarcation strip 38 and through seal (not shown) sealing (with reference to Fig. 5, Fig. 8), therefore, warm braw 50A can not enter this second blast channel 39B, and warm braw 50A can not blow out from the second blow-off outlet 37B.
In Figure 10 of Fig. 7 of the first embodiment and the second embodiment, respectively expression make switching valve 36 to arrow 40B direction rotate and second place P2.To remain airtight construction between the inner peripheral surface of warm braw inlet portion 41 and switching valve 36 by not shown seal between the inner peripheral surface of switching valve 36 and warm braw inlet portion 41.
Thus, warm braw 50B such as the Fig. 7, shown in Figure 10 of blast pipe 25 (with reference to Fig. 3) have been passed through, only be directed to the second blast channel 39B that is separated by switching valve 36 and demarcation strip 38 at warm braw inlet portion 41, and be blown out to cylinder 5 inside from the second blow-off outlet 37B (37D).On the other hand, the the first blast channel 39A that is connected with the first blow-off outlet 37A (37C) seals through seal (not shown) by switching valve 36 and demarcation strip 38, therefore warm braw 50B can not import to the first blast channel 39A, and warm braw 50B can not blow out from the first blow-off outlet 37A (37C).
Fig. 6 of the first embodiment represents the 3rd position P3, and the 3rd position P3 is the centre position between the second place P2 of the primary importance P1 of switching valve shown in Figure 5 36 and switching valve 36 shown in Figure 7.Similarly, Fig. 9 of the second embodiment represents the 3rd position P3, and the 3rd position P3 is the centre position between the second place P2 of the primary importance P1 of switching valve shown in Figure 8 36 and switching valve 36 shown in Figure 10.
The switching valve 36 at the 3rd P3 place, position shown in Figure 9 of Fig. 6 of the first embodiment, the second embodiment does not contact with the inner peripheral surface of warm braw inlet portion 41.
Under the state shown in Figure 9 of Fig. 6 of the first embodiment, the second embodiment, when being blown into warm braw 50 from blast pipe 25 to warm braw inlet portion 41, a part of warm braw 50A of warm braw 50 is imported into the first blast channel 39A, then be blown out to cylinder 5 inside from the first blow-off outlet 37A (37C), another part 50B of warm braw 50 is imported into the second blast channel 39B, then is blown out to cylinder 5 inside from the second blow-off outlet 37B (37D).
Here, in the structure of Figure 10, make the area of the first blow-off outlet 37C and the second blow-off outlet 37D different at Fig. 8 of the second embodiment, for example make the area of the first blow-off outlet 37C less, make the area of the second blow-off outlet 37D larger.
As shown in Figure 8, primary importance P1 at switching valve 36, when blowing out warm braw 50A from the first blow-off outlet 37C, because the fluid resistance of blow-off outlet is large, so flow velocity is large but air quantity is little, as shown in figure 10, at the second place P2 of switching valve 36, when blowing out warm braw 50B from the second blow-off outlet 37D, the fluid resistance of blow-off outlet is little, therefore flow velocity is little, but air quantity is large.
In addition, at the 3rd position P3 shown in Figure 9 of the second embodiment, owing to blowing out warm braw 50A, 50B from the first blow-off outlet 37C and the second blow-off outlet 37D, therefore, the fluid resistance of blow-off outlet is minimum, so the air quantity of warm braw 50A, 50B is maximum.
Like this, in the second embodiment, by as Fig. 8, Figure 10, change as shown in Figure 9 the area of blow-off outlet, can change air quantity and the wind speed of warm braw 50.
Here, at the primary importance P1 shown in Figure 8 of the second embodiment, the speed of establishing the warm braw 50A that blows out from the first little blow-off outlet 37C of area is the speed of for example 100m (rice)/more than s (second), and air quantity is 1.4m
3(cubic meter)/minute more than, can launch by the blast of warm braw 50A the fold of the washings 14 such as clothing, can make quality good.
In addition, in case be that the washings 14 such as clothing is in the situation that dry with fold, even after this blow warm braw 50 to the washings such as clothing 14 at high speed, fold is not unfolded yet, therefore, in order to make quality good, also need also to blow constantly warm braw 50A at a high speed until dry complete very moist state from the washings such as clothing 14.
On the other hand, at second place P2 shown in Figure 10, when blowing out warm braw 50 from the second large blow-off outlet 37D of area, perhaps when the 3rd position P3 shown in Figure 9 blows out warm braw 50 from the first blow-off outlet 37C and the second blow-off outlet 37D, wind speed for example can be reduced to 20m/s, but air quantity can increase to 2m
3/ more than dividing.Perhaps, if the air quantity of warm minute 50 keeps 1.4m
3/ divide to get final product, even further reduce the rotary speed of fan 18, also can obtain the air quantity of warm braw 50, therefore, can reduce the power that is applied to fan drive motor 20 (with reference to Fig. 1), can realize the low consumption electrification, have energy-conservation effect.
[driving mechanism of switching valve 36]
Next, one example of the driving mechanism of the switching valve 36 of Fig. 5～shown in Figure 10 is described to Figure 12 by Figure 11.
Figure 11 observes the stereogram of an example of driving mechanism of the expression switching valve 36 of blast pipe 23 from the direction opposite with the blast pipe shown in Figure 8 23 of Fig. 5 of the first embodiment and the second embodiment (Fig. 5, shown in Figure 8 B direction).Figure 12 observes the stereogram of an example of driving mechanism of the expression switching valve 36 of blast pipe 23 from the direction opposite with Fig. 7 and Figure 10 (Fig. 7, shown in Figure 10 C direction).
As Figure 11, shown in Figure 12, being fixed with on the rotation fulcrum 35 of switching valve 36, be fixed with cursor 42, when making cursor 42 rotation, switching valve 36 is through 35 rotations of rotation fulcrum.
With respect to one of cursor 42 distolateral rotation fulcrum 35, at another distolateral fulcrum 43 that is provided with of cursor 42, be connected with rotationally an end of connecting rod 44 on this fulcrum 43, cursor 42 links rotationally through the end of fulcrum 43 with connecting rod 44.
And the other end of connecting rod 44 is connected in fulcrum 46 rotationally, and this fulcrum 46 is arranged at an end of the actuating arm 47 that is driven by transfer valve motor 45, and the other end of connecting rod 44 is connected with actuating arm 47 rotationally through this fulcrum 46.
Under state shown in Figure 11, switching valve 36 rotates significantly and is in primary importance P1 (top dead-centre) (with reference to Fig. 5, Fig. 8) to arrow 40A direction, contact with switching valve 36 by the inner peripheral surface that makes warm braw inlet portion 41, keep airtight construction through not shown seal.
Under state shown in Figure 12, switching valve 36 significantly rotates and is in second place P2 (bottom dead centre) (with reference to Fig. 7, Figure 10) to arrow 40B direction, contact with switching valve 36 by the inner peripheral surface that makes warm braw inlet portion 41, keep airtight construction through not shown seal.
Namely, by making 45 reciprocating motions of transfer valve motor, switching valve 36 is moved between top dead-centre (primary importance P1) (with reference to Figure 11) and bottom dead centre (second place P2) (with reference to Figure 12), thereby switch the first blow-off outlet 37A (37C) (with reference to Figure 11) and the second blow-off outlet 37B (37D) (with reference to Figure 12).
In addition, also be provided with: the first detecting unit 48, it detects the situation that switching valve shown in Figure 11 36 is positioned at upper dead center position (primary importance P1) (with reference to Fig. 5, Fig. 8); And second detecting unit 49, it detects the situation that switching valve shown in Figure 12 36 is positioned at lower dead point position (second place P2) (with reference to Fig. 7, Figure 10).
These first detecting units 48 and the second detecting unit 49 can be the microswitches that for example detects the position of actuating arm 47, can be perhaps the Hall IC that the magnet that is arranged at actuating arm 47 is detected, can be also perhaps the light-emitting component of the photo-coupler that detects of the situation to a part of shading of actuating arm 47 and a pair of element that photo detector forms.
In addition, the one the second detecting units 48,49 can also detect switching valve 36 driving mechanisms except actuating arm 47 or the motion of switching valve 36.
In addition, it can be also the approach switch that the actions of the action of the driving mechanism of the actuating arm 47 that comprises switching valve 36 or switching valve 36 itself is detected in non-contacting mode, be positioned at upper dead center position (primary importance P1) or lower dead point position (second place P2) as long as can detect switching valve 36, the structure of the first detecting unit 48 and the second detecting unit 49 can suitably be selected.
[control system]
Figure 13 means the block diagram of structure of the control system of index drum formula scrubbing-and-drying unit 1.
On guidance panel shown in Figure 1 51, as mentioned above, the various switch 51s that are provided with the display 51h that comprises various demonstrations and comprise power supply, these displays 51h, various card close 51s and are connected with display part, the key input part of shown in Figure 13 function circuit section 94 respectively.

[action of drum-type washing drying machine 1]
Next the action of drum-type washing drying machine shown in Figure 11 described.
At first, the summary operation of the washing drying in drum-type washing drying machine 1 is described.
Figure 14 means the figure of general flowchart of the standard procedure of drum-type washing drying machine 1.
At first, the user presses the power switch of guidance panel shown in Figure 1 51, and standard procedure switch 51s is connected, and at this moment, begins to carry out the action of standard procedure, carries out successively the washing of washings 14, twice middle dehydration post rinse, final dewatering and drying.
With reference to Figure 14, at first, the power switch of user's push panel 51 (with reference to Fig. 1) switches on power, connects standard procedure switch 51s, and at this moment, the cloth amount of carrying out washings 14 detects (step 1).And afterwards, the user puts into washing agent (step 20).
Carrying out necessary water pipe water supply (step 2) afterwards, wash (step 3), washings are carried out draining (step 4).Afterwards, for contained washing agent in the washings 14 of back-outing, carry out middle dehydration (step 5) for the first time, in order then to carry out rinsing for the first time, water supply start (step 6).
After primary rinsing (step 7) finishes, carry out the draining (step 8) of these washings.After this, for the washing agent that also contains in the washings 14 of back-outing, carry out secondary middle dehydration (step 9), in order to carry out secondary rinsing water supply start (step 10).
After secondary rinsing (step 11) finishes, these washings are carried out draining (step 12), then carry out final dewatering (step 13).
At last, carry out drying (step 14), thereby finish washing and dry.
[action control 1 of switching valve 36]
Next, an example of the action control (with reference to Fig. 5, Fig. 6, Fig. 7) of the switching valve 36 in drying process (step 14 of Figure 14) described.
As an example, how many judgements of cloth amount that detect according to the cloth amount based on washings 14 are described, carry out the example that wind direction is controlled.
in general flowchart shown in Figure 14, carried out the cloth amount at the cloth amount detection unit by washings 14 and detected (step 1) afterwards, in the amount that consequently is judged as washings 14 in the situation that below 3kg, the cloth amount is thought on a small quantity, in the step 14 of Figure 14, as shown in Figure 7, mobile switching valve 36 blows out warm braw 50B from the second blow-off outlet 37B, arrow 34B as shown in Figure 3 makes the wind direction of warm braw 50B like that near the lower surface or lower surface of cylinder 5, thus, concentrate near the state the lower surface of cylinder 5 for a small amount of washings 14, can make expeditiously warm braw 50B blow near a small amount of washings 14 of lower surface of cylinder 5.
On the other hand, detect (step 1 of Figure 14) afterwards in the cloth amount of having carried out washings 14, surpassed 3kg in the situation that consequently be judged as the amount of washings 14, the amount of washings 14 is more, and washings 14 is full of the inside of cylinder 5.
Therefore, in the step 14 of Figure 14, as shown in Figure 5, mobile switching valve 36 blows out warm braw 50A from the first blow-off outlet 37A, shown in the direction of arrow 34A as shown in Figure 3, the blow-off direction that makes warm braw 50A be wind direction near the central authorities or central authorities of cylinder 5, make thus warm braw 50A blow to the central authorities of washings 14.
Like this, by the suitable wind direction of how much selecting corresponding to the amount of washings 14, thus, can effectively promote moisture from washings 14 evaporations, thereby can improve drying efficiency.
[action control 2 of switching valve 36]
As other embodiment, the example that first half term and the second half at drying process (step 14 of Figure 14) are changed air quantity or wind speed describes.
Under the state that final dewatering operation (step 13) shown in Figure 14 is completed, washings 14 is in wet well-proportioned state in the inside of cylinder 5, therefore, first half term in drying process (step 14 of Figure 14), in order to promote moisture from wet that well-proportioned washings 14 evaporates, preferably make warm braw 50 blow to washings 14 integral body by increasing air quantity, to promote moisture from washings 14 evaporations.
but, from blow-off outlet 37 (37A, 37B, 37C, 37D) (with reference to Fig. 5, Fig. 8) near the washings 14 of the nearby side the peristome 5a of very near cylinder 5 is due to the warm braw 50 (50A that directly are dried, 50B) (with reference to Fig. 5, Fig. 8) blow to, therefore easily dry, on the contrary, the warm braw 50 of the washings 14 by being in cylinder 5 inboards (the paper right side of Fig. 3) has passed through nearby between the washings 14 of the humidity of side (the paper left side of Fig. 3), humidity uprises, and be used for making the latent heat of moisture evaporation to be seized, the temperature step-down, therefore, moisture is not easy evaporation.
Therefore, the second half at drying process, become following washings 14 and produced the even state of uneven drying: the washings 14 of the nearby side of cylinder 5 (left side of cylinder 5 shown in Figure 3) is drying, but the washings of cylinder 5 inboards (right side of cylinder 5 shown in Figure 3) 14 or humidity.
Like this, in order to make washings 14 dryings that produced the even state of uneven drying, need to be blown into warm braw 50, make warm braw 50 pass through the nearby washings 14 of side (left side of cylinder 5 shown in Figure 3), and arrive or the washings 14 of moist cylinder 5 inboards (right side of cylinder 5 shown in Figure 3).
For this reason, preferably, restriction blows out the area of outlet (blow-off outlet 37) of warm braw 50 (50A, 50B) (with reference to Fig. 5, Fig. 8), make the speed of blowing out at a high speed to improve pressure, make warm braw 50 blow to fiercely washings 14.
Namely, preferred such structure: in the first half term of drying process, for example the second embodiment is shown in Figure 10, the second blow-off outlet 37D large from area is blown into a large amount of warm braw 50B in cylinder 5, promote the drying that washings (14) is whole, in the second half of drying process, for example the second embodiment is shown in Figure 8, the first blow-off outlet 37C little from area is blown into warm braw 50A fiercely, so that inboard washings 14 dryings.
Perhaps, also can be in the first half term of drying process, shown in Figure 9 as the second embodiment blows out warm braw 50 (50A, 50B) in large quantities from the first blow-off outlet 37C and two blow-off outlets of the second blow-off outlet 37D.
As an example of the switching of the one the second blow-off outlet 37C, the 37D of the first half term that is used for carrying out such drying process and the second half, in the switching of carrying out the one the second blow- off outlet 37C, 37D from drying process begins after through the scheduled time.
About this scheduled time, detect the testing result of (step 1 of Figure 14) according to the cloth amount of washings 14, in the situation that the amount of washings 14 is many, because the time consumption of drying must be long, therefore, this scheduled time is also long, in the situation that the amount of washings 14 is few, because the time of drying is very short, therefore should set the scheduled time shortlyer, can make according to the amount of washings 14 like this warm braw 50 air quantity switching time just in time.
Perhaps, also can carry out according to the hygrometry result of being measured by humidity sensor 90 (with reference to Figure 13) switching of the one the second blow- off outlet 37C, 37D.
Namely, preferred such structure: in the situation that from beginning is dry humidity more than predetermined value, shown in Figure 10 as the second embodiment, the second blow-off outlet 37D large from area is blown into a large amount of warm braw 50B, be dried and make humidity reduce gradually and reach below predetermined value in the situation that arrived the second half, the washings 14 of drying process, for example the second embodiment is shown in Figure 8, and the first blow-off outlet 37C little from area blows out warm braw 50A fiercely.
Perhaps, also can be in the first half term of drying process in the situation that humidity also more than predetermined value, shown in Figure 9 as the second embodiment blows out warm braw 50 (50A, 50B) in large quantities from the first blow-off outlet 37C and two blow-off outlets of the second blow-off outlet 37D.
[action control 3 of switching valve 36]
In addition, as other example, following example is described: can select the preferential pattern of dry mass and the preferential pattern of drying efficiency, blow out suitable warm braw 50 according to selected pattern.
That crosses as previously explained is such, when from washings 14 also very moist state to the area of the complete restriction warm braw of drying blow-off outlet (the one the second blow- off outlet 37C, 37D (with reference to Fig. 8)) and when continuing to blow out at a high speed warm braw 50, utilize the blast of warm braw 50, fold is unfolded, and quality is good.
On the other hand, when the area that enlarges warm braw blow-off outlet (the one the second blow- off outlet 37C, 37D (with reference to Fig. 8)) and when continuing to blow out a large amount of warm braws 50, promoted the evaporation of moisture, drying efficiency is improved, therefore, can shorten drying time and save energy, if further reduce the rotary speed of fan 18 (with reference to Fig. 1), can be more energy-conservation.
Here, be provided with selection take good quality as preferential high quality mode with take shortening drying time and energy-conservation drying mode selected cell as preferential high efficiency mode on guidance panel 51, for example be provided with for any the pushbutton switch 51s that selects high quality mode and high efficiency mode, pushbutton switch 51s is connected with the key input part (with reference to Figure 13) of function circuit section 94.And, if when having selected high quality mode, in drying process, shown in Figure 8 as the second embodiment, the first blow-off outlet 37C little from area blows out warm braw 50A fiercely, when having selected high efficiency mode, in drying process, shown in Figure 10 as the second embodiment, the second blow-off outlet 37D large from area blows out warm braw in large quantities, can blow out suitable warm braw 50 according to selected pattern, therefore, very preferably.
In the situation that selected high efficiency mode, also can be as the second embodiment shown in Figure 9, blow out a large amount of warm braw 50A, 50B from the first blow-off outlet 37C and two blow-off outlets of the second blow-off outlet 37D.
in addition, Fig. 5 about above-mentioned embodiment, the first blow-off outlet 37A shown in Figure 8, 37C and the second blow- off outlet 37B, 37D, in the first embodiment that reference Fig. 5 illustrated to Fig. 7, separately direction is different in the first blow-off outlet 37A and the second blow-off outlet 37B, make change of the wind, and in the second embodiment that reference Fig. 8 illustrated to Figure 10, the first blow-off outlet 37C is different with the second blow-off outlet 37D area separately, air quantity is changed, but about the first blow- off outlet 37A, 37C and the second blow- off outlet 37B, 37D, also can make area and direction neither same, air quantity and wind direction are changed together.
[mode of texturing of the second embodiment of the air quantity of change warm braw 50 (50A, 50B)]
Next, by Figure 15, Fig. 8 of the air quantity that changes warm braw 50 is described to other modes of texturing of the second embodiment shown in Figure 10.
In addition, Figure 15 is that face side (the arrow A direction of Fig. 1) is observed near the stereogram that comprises the major part cutaway view of blast pipe 23 of the mode of texturing of the second embodiment in the past.
The first blow-off outlet 37E is the little blow-off outlet that can blow out at high speed warm braw of area, when different from Fig. 8 of the second embodiment, switching valve 36 is (label 36 that represents with double dot dash line in reference to Figure 15 ') when having rotated to arrow 40A direction, and switching valve 36 is in and the internal perisporium of warm braw inlet portion 41 position relationship of butt not.
In Figure 15 of mode of texturing, when switching valve 36 has been rotated to the direction of arrow 40B (label 36 that represents with solid line in reference to Figure 15), warm braw 50 only is directed in the first blow-off outlet 37E by switching valve 36 and demarcation strip 38, and is blown at high speed the inside of cylinder 5.
On the other hand, switching valve 36 rotates and when being in the position of label 36 ' (representing with double dot dash line) in Figure 15 to the direction of arrow 40A, warm braw 50E, 50F are the same with Fig. 9 of the second embodiment, flow through the both sides of switching valve 36 and the both sides of demarcation strip 38 and blow out from the first blow-off outlet 37E and the second blow-off outlet 37F.In addition, in Figure 15 of mode of texturing, can not realize the mode that warm braw 50 only blows out from the second blow-off outlet 37F.
Here, about the warm braw 50E that blows out from the first blow-off outlet 37E, if be suitable for blowing out warm braw 50, blow-off outlet small size of the high speed corresponding with above-mentioned high quality mode, when making switching valve 36 arrive the position of label 36 ' (representing with double dot dash line) to the direction rotation of arrow 40A in Figure 15, the blow-off outlet that adds up to from the area with the first blow-off outlet 37E and the second blow-off outlet 37F blows out warm braw 50E, 50F, therefore can increase air quantity.
In addition, in the above-described embodiment, rotate about making switching valve 36, the situation of application transfer valve motor 45 (with reference to Figure 13) has been described, but also can have replaced motor with solenoid.
[action effect]
