In addition, the water supply pipe (not shown) being provided with feed water valve is connected with tank 2 with the drainpipe 40 being provided with draining valve 27.
Below, the circulating path of the drying air making cloth drying in the drum-type washing drying machine of present embodiment is specifically described.
As shown in Figure 1, first, for making the drying air of washings drying be sent in cylinder 1 via air supplying part 4.Moisture state is become from the washings deprives moisture in cylinder 1 by the drying air of blowing.The drying air of moisture state is discharged to the outside of cylinder 1 by the outlet 5 being arranged on the position of the side periphery of cylinder 1.By dehumidification portion 6, discharged drying air is dehumidified.By heating part 7, the drying air after being dehumidified by dehumidification portion 6 is heated.
In addition, the drying after heating by air supplying part 4, is switched to first air channel 9 or second air channel 11 by air channel switching part 12 with air.Then, the drying air being directed into the first air channel 9 or the second air channel 11 by switching is blown out in cylinder 1 again, carries out by this way circulating carrying out drying to the clothing in cylinder 1.
And as shown in Figure 1, the first air channel 9 has the first blow-off outlet 8 of the rearward openings at cylinder 1, blows out drying air from the first blow-off outlet 8 in cylinder 1.In addition, the second air channel 11 has the second blow-off outlet 10 of all lateral openings in the front of cylinder 1, blows out drying air from the second blow-off outlet 10 in cylinder 1.
Now, the air being formed as first blow-off outlet 8 in the first air channel 9 is large by sectional area by the air of sectional area ratio second blow-off outlet 10.Thus, the pressure loss is few compared with the second air channel 11, can blow out the drying air of Wind Volume in cylinder 1.
In addition, the air being formed as second blow-off outlet 10 in the second air channel 11 is little by sectional area by the air of sectional area ratio first blow-off outlet 8.Therefore, compared with the first blow-off outlet 8, the higher drying air of wind speed can be blown out in cylinder 1.
In addition, as shown in Figure 1, usually, when drum-type washing drying machine, the gap of carrying out between the front of the cylinder 1 rotated and tank 2 is formed as little as far as possible (narrow) to prevent clothing of nipping.Therefore, arrange few, that the there is big uncork blow-off outlet of the pressure loss in the gap to be spatially difficult to realize.Therefore, the gap between the front of cylinder 1 and tank 2 is provided with air by smaller the second blow-off outlet 10 of sectional area.
On the other hand, the space more than needed for arranging first blow-off outlet 8 with larger opening is there is in the bottom of the rear inner part of cylinder 1.Therefore, the first fewer blow-off outlet 8 of the pressure loss is provided with in the bottom at cylinder 1 rear.Now, cover the first blow-off outlet 8 by the cover 26 large with the aperture opening ratio comprising a lot of diameter holes that can ventilate, prevent clothing (washings) from being bitten into the first blow-off outlet 8.
In addition, the rotating shaft of the cylinder 1 be obliquely installed after height before making as the drum-type washing drying machine of present embodiment rotates and stirs clothing lowly, the little clothings such as such as socks, handkerchief, panties easily focus on the rear inner part of cylinder 1.On the other hand, such as long-sleeved vest, long sleeves cutter shirt, the isometric clothing of long sleeves nightwear easily focus on the front of cylinder 1.
Therefore, when carrying out drying under the state that little clothing and the mixing of robe thing exist, when blowing out the drying air of Wind Volume from first blow-off outlet 8 of position of the rear inner part being arranged on cylinder 1, first drying air contacts the little clothing of the rear inner part focusing on cylinder 1.Afterwards, with little contact with clothing while the drying air passed arrives the robe thing in cylinder 1 front.That is, by blowing out the drying air of Wind Volume from the first blow-off outlet 8, all can effectively and carry out drying with the state that uneven drying is few to little clothing and robe thing.
Therefore, as shown in Figure 1, air channel switching part 12 is set in first air channel 9 in downstream and the branch place in the second air channel 11 that are formed at air supplying part 4, correspondingly the path of drying air is switched to the first air channel 9 or the second air channel 11 with the situation such as amount, kind of clothing.

Then, in the region of the dry ending phase of drying process, control part 70 controls air channel switching part 12 and is switched to the first air channel 9, is blown into the drying air of Wind Volume and makes drying air and contact with clothing from first blow-off outlet 8 in the first air channel 9 with low wind speed.
That is, in each region of drying process, by switching the first air channel 9 and the second air channel 11, drying air and contact with clothing can be made effectively to make cloth drying, and can uneven drying be reduced.Further, clothing can be suppressed to produce fold.
In addition, in the drum-type washing drying machine of present embodiment, in drying process, the temperature based on the glass pane 36 detected by the temperature detecting part 71 being arranged at glass pane 36 carries out selective switching to the first air channel 9 and the second air channel 11.
Specifically, when temperature detecting part 71 detects the first set point of temperature A in drying process process, control part 70 controls air channel switching part 12 in the dry incipient stage of drying process to dry mid-term stage, to be switched to the first air channel 9 from the second air channel 11 of blowout drying air.
That is, during the dry incipient stage and dry mid-term stage of the low drying process of the temperature of glass pane 36, use the second air channel 11 to make high wind speed, the drying air of little air quantity contacts clothing.Thus, the drying air blown out from second blow-off outlet 10 in the second air channel 11 is utilized effectively to carry out drying to clothing.Consequently reduce the uneven drying of clothing.
But during the dry ending phase of drying process, the amount of moisture contained in clothing is few, the temperature being therefore positioned at the glass pane 36 near the second blow-off outlet 10 due to the drying air of the high temperature from the second blow-off outlet 10 blowout rises.Therefore, when the temperature detecting part 71 being arranged at glass pane 36 detects the first set point of temperature A preset, control part 70 controls air channel switching part 12 and is switched to the first air channel 9.Thereby, it is possible to suppress the temperature of the glass pane 36 caused by the drying air of the high temperature blown out from the second blow-off outlet 10 to rise.In addition, even if preferably the first set point of temperature A to be set as that user touches such as less than 60 degree that glass pane 36 also can not scald.
Then, after drying air and the contact with clothing of the high temperature of blowing from first blow-off outlet 8 at the rear being arranged on cylinder 1 being switched to the first air channel 9 and temperature decline, from outlet 5 discharge process, the front of the cylinder 1 residing for glass pane 36 is being passed through.Therefore, the drying air declined by temperature can make the temperature of glass pane 36 reduce.Thus, the temperature of glass pane 36 can not be made to rise to more than the first set point of temperature A, and, by from first blow-off outlet 8 blow low wind speed, Wind Volume drying air can make cloth drying.
That is, according to the present embodiment, the temperature based on glass pane 36 controls air channel switching part 12 and switches the first air channel 9 and the second air channel 11, the temperature of glass pane 36 can be controlled within the first set point of temperature A thus.Therefore, there is no need for the time of the cooling glass pane 36 opening and closing door body 35 in dry operating process, after dry operating immediately.Consequently, not carrying out just can removing door lock portion by suspending the refrigerating work procedure cooling glass pane 36 in dry operating process, at any time can both take out clothing immediately in cylinder 1.
In addition, do not need the power consumption in the past cooled in refrigerating work procedure needed for glass pane 36, therefore, it is possible to reduce power consumption.
Further, do not need to cool glass pane 36, even if the clothing being easy to drying comprising a large amount of chemical fibre therefore such as also easily can be taken out in dry operating process.Consequently can prevent from being easy to the super-dry of dry clothing in advance.
Below, the reason being switched to the first air channel 9 in the present embodiment during the dry ending phase of drying process is described.
Usually, during the dry ending phase that the temperature of glass pane 36 rises, the amount of moisture contained in clothing is few, and therefore contacting with drying air and moisture is evaporated needs the time.Therefore, during dry ending phase, in cylinder 1, send the drying air of Wind Volume, low wind speed from first blow-off outlet 8 in the first air channel 9, moisturize the chance contacted with drying air.Now, with the air of second blow-off outlet 10 in the second air channel 11 by compared with sectional area, the air of first blow-off outlet 8 in the first air channel 9 is large by sectional area, and therefore the pressure loss in the first air channel 9 is few compared with the second air channel 11.Therefore, even if drive air supplying part 4 with few power consumption, the drying air of Wind Volume also can be obtained.Consequently, the drying time in during the dry ending phase of drying process can be shortened and reduction power consumption during this period.
In addition, the refrigerating work procedure carrying out cooling glass pane 36 as drum-type washing drying machine in the past because glass pane 36 becomes high temperature before take out clothing in cylinder 1 is not needed.Thereby, it is possible to take out clothing at any time in cylinder 1 in dry operating.Consequently, can realize that total drying time is short, power consumption is few and the good cloth drying effect that the uneven drying of clothing is also few.
Below, with reference to Fig. 1 utilize Fig. 4 another example to the control action in the drying process of the drum-type washing drying machine of present embodiment to be described in detail.
Fig. 4 is that air channel switching part in another example of the drum-type washing drying machine represented involved by present embodiment is to the sequential chart of an example on the opportunity that the first air channel and the second air channel switch.
As mentioned above, the drum-type washing drying machine shown in Fig. 1 possess near outlet 5 or outlet 5 to contact with clothing after the discharge temperature test section 72 such as the such as thermistor that detects of the temperature of drying air of discharging from cylinder 1.
In the present embodiment, as the following detailed description of, the temperature based on the drying air of the outlet 5 detected by discharge temperature test section 72 judges the dry incipient stage in drying process, the period of dry mid-term stage and dry ending phase controls air channel switching part.
First, during the preheating in the drying process shown in Fig. 4, be described during constant-rate method of drying and between lapse rate dry period.
Generally when fully wetting clothing is placed under fixing drying condition (such as, be placed on situation about having in the drying air of fixing temperature, humidity and wind speed), the temperature of the index of aridity as shown in Figure 4 in drying process and drying air changes, and to be divided between preheating period A, constant-rate method of drying period B and lapse rate dry period between C tri-dry periods.
That is, preheating period A is during due to the heat of drying air, clothing is heated.There is moisture on the surface of clothing in constant-rate method of drying period B, moisture from the surperficial constant of clothing evaporate and the permanent rate of the quality of moistening clothing reduce during.Between lapse rate dry period, C is that the moisture of clothing surface disappears, and the moisture from the inside of clothing to surface moves the evaporation be unable to catch up with from clothing surface, and the surface temperature of clothing rises and during the index of aridity (rate of drying) declines gradually.
And, as shown in Figure 4, in drying process, rise gradually in preheating period A with the temperature of the drying air after contact with clothing, in constant-rate method of drying period B, become fixed temperature, again rise in C between lapse rate dry period.
In addition, usually, also carry out the drying of clothing in constant-rate method of drying period B, the index of aridity mass ratio of the clothes weight as benchmark of state (after clothing moistening in dry run and the drying) rises.But, in constant-rate method of drying period B, little with the variations in temperature of the drying air after contact with clothing.Therefore, even if measuring tempeature change, the change grasping the index of aridity in constant-rate method of drying period B according to variations in temperature is also difficult to.
On the other hand, for scrubbing-and-drying unit in recent years, due to the raising of dewatering, the moisture of the clothing of washing and the drying process start time after dewatering is quite low, and being dried to the index of aridity is 85% ~ 86%.
Therefore, if make the high drying air (the drying air that Wind Volume, humidity are low) more than this degree of drying capacity contact clothing under the state that cloth drying to the index of aridity is 85% ~ 86% as in the present embodiment, then the temperature of the index of aridity in drying process and drying air changes as shown in Figure 4.That is, even if in preheating period A, also there is evaporation to a certain degree in the moisture of clothing surface.
Therefore, the constant-rate method of drying period B after preheating period A exists hardly with regard to becoming that clothing surface is dry in a way that moisture from clothing inside moves the state of being unable to catch up with evaporating, and namely from drying process starts, becomes C between lapse rate dry period within blink.
And, between lapse rate dry period in C, rise gradually with the temperature of the drying air after contact with clothing.Therefore, according to the variations in temperature of drying air, the index of aridity of dry development situation, the i.e. clothing of clothing can be estimated.
But, when the drying of heating type in the past, utilize heater to carry out heating to form drying air to the air after only utilizing the water-cooled of running water, utilizing the air cooling of space air to dehumidify.Therefore, be difficult to as present embodiment, realize C between the lapse rate dry period shown in Fig. 4 and account for most drying process.
That is, as in the present embodiment, by use to utilize the cold-producing medium of enough low temperature to the drying air of the Wind Volume that the heat pump mode that large quantity of air dehumidifies obtains, can realize as shown in Figure 4 there is constant-rate method of drying period B hardly and between lapse rate dry period C account for most drying process.Therefore, in the present embodiment, heat pump assembly 50 is preferably utilized to carry out the structure of cloth drying with heat pump mode.
Therefore, in the present embodiment, between lapse rate dry period, C accounts in most drying process, and the temperature of the drying air that control part 70 detects based on the discharge temperature test section 72 by outlet 5 carrys out the temperature of estimating window glass 36.Specifically, in order to the temperature of glass pane 36 being controlled wait below the first set point of temperature A at such as 60 degree, when the temperature of the drying air detected by discharge temperature test section 72 reaches the second set point of temperature B, control part 70 controls air channel switching part 12 and switches to the first air channel 9 from the second air channel 11.
That is, when switching to the first air channel 9 from the second air channel 11 in moment of arrival second set point of temperature B, from the drying air of blowing with the first blow-off outlet 8 that first air channel 9 at the rear being arranged on cylinder 1 is connected after contacting clothing by the front of the cylinder 1 residing for glass pane 36, discharge from outlet 5.Consequently, by with contact clothing after the drying air that declines of temperature contact, the temperature of glass pane 36 can be made to reduce.
In addition, even if when the temperature of the drying air detected by discharge temperature test section 72 is below the second set point of temperature B, the period of the dry incipient stage in drying process, dry mid-term stage and dry ending phase also can be judged as described below.
In this case, the period of control part 70 and the dry incipient stage in the drying process judged, dry mid-term stage and dry ending phase correspondingly controls air channel switching part 12, switches the first air channel 9 and the second air channel 11 in good time.Specifically, the dry incipient stage is judged as during till control part 70 reaches a certain specific temperature from the temperature of the drying air detected by discharge temperature test section 72 after being started by drying process.In addition, dry mid-term stage is judged as during the temperature to the drying air detected by discharge temperature test section 72 after being judged as the dry incipient stage is arrived the specified temp of high temperature by control part 70 further.In addition, control part 70 by after being judged as dry mid-term stage to drying process terminates during be judged as dry ending phase.Thereby, it is possible to the period of the dry incipient stage in judgement drying process, dry mid-term stage and dry ending phase.
In addition, the temperature (that is, flowing into the temperature of the drying air of cylinder 1) roughly fixing (comprising fixing) of the drying air heated by heating part 7.Therefore, the period of the dry incipient stage of drying process, dry mid-term stage and dry ending phase only also can be judged based on the temperature of the drying air detected by discharge temperature test section 72.
Another example according to the present embodiment, the testing result based on the temperature of the drying air detected by discharge temperature test section 72 carrys out the temperature of estimating window glass 36, sets the second set point of temperature B.Then, in drying process process, when discharge temperature test section 72 detects the second set point of temperature B, by air channel switching part 12, first air channel 9 and the second air channel 11 are switched in good time.Thereby, it is possible to the temperature of glass pane 36 is controlled at below the first set point of temperature A.
In addition, another example according to the present embodiment, in the process of drying process, is provided with the region carrying out drying clothes from the first blow-off outlet 8 with Wind Volume blowout drying air.Therefore, do not need as in the past, to arrange refrigerating work procedure to utilize the drying Air flow glass pane of high pressure, high wind speed, therefore, it is possible to reduce total power consumption.Thereby, it is possible to realize power saving and the uneven drying of clothing can be reduced and realize good cloth drying effect.
Below, with reference to Fig. 1, Fig. 2 and Fig. 4 utilize Fig. 5 another example to the control action in the drying process of the drum-type washing drying machine of present embodiment to be described in detail.
Fig. 5 is that air channel switching part in another example of the drum-type washing drying machine represented involved by present embodiment is to the sequential chart of an example on the opportunity that the first air channel and the second air channel switch.In addition, Fig. 5 show the amount of clothing few time sequential chart, Fig. 4 show the amount of clothing many time sequential chart.
The difference of present embodiment and above-mentioned embodiment is, utilizes the cloth amount test section 15 shown in Fig. 2, correspondingly controls air channel switching part 12 switch the first air channel 9 and the second air channel 11 with the amount of the clothing put in cylinder 1.
That is, in the embodiment that the above-mentioned Fig. 3 of utilization, Fig. 4 are illustrated, control part 70 judges period of each period of the dry incipient stage in drying process, dry mid-term stage and dry ending phase based on the temperature of the temperature of the glass pane 36 detected by temperature detecting part 71 and discharge temperature test section 72, the drying air of outlet 5.
But usually different according to the amount of the clothing as dry object, the relation between the temperature of the drying air detected by discharge temperature test section 72 and the temperature of the glass pane 36 detected by temperature detecting part 71 is different based on following reason.
Reason is, the amount as the clothing of dry object is more, and the surface area of the clothing contacted with drying air is larger, and therefore the evaporation capacity that evaporates from clothing surface of moisture is also more.If the evaporation capacity of moisture is many, then the heat of drying air just consumes more.Therefore, the amount as the clothing of dry object is more, and the temperature of the drying air detected by discharge temperature test section 72 after contact clothing is lower.
In addition, when the amount of clothing is many, the chance of contact with clothing glass pane 36 increases, and compared with rising with the temperature of discharge temperature test section 72, the temperature of glass pane 36 presents the slow tendency of climbing.On the other hand, when the amount of clothing is few, compared with rising with the temperature of discharge temperature test section 72, the temperature of glass pane 36 presents the fast tendency of climbing.That is, compared with the second set point of temperature B set by the temperature utilizing the drying air after contacting clothing, the temperature of glass pane 36 correspondingly changes with the amount as the clothing of dry object, and the temperature of the more glass panes of amount 36 of clothing is lower.
That is, according to the amount of clothing is different, temperature that is that detected by discharge temperature test section 72 is different with the temperature detected by temperature detecting part 71.
Therefore, in the present embodiment, profit cloth consumption test section 15 detects the amount of the clothing as dry object, based on the testing result of the cloth amount detected, judges that the second set point of temperature B of (estimation) benchmark changes by the method illustrated below to the temperature as glass pane 36.
First, before washing starts, control part 70 utilizes the cloth amount test section 15 shown in Fig. 1 and Fig. 2 to detect the amount (quality) putting into the clothing of cylinder 1.Specifically, first, cloth amount test section 15 pairs of tanks 2 are that the position of the axle of damper 14 under empty state (do not have water in tank 2, do not drop into the state of clothing to cylinder 1) is detected.Then, position washing being started to the axle of the damper 14 under front and state before injecting from water to tank 2 (do not have water in tank 2 but in cylinder 1 state of clothing) is detected.Then, control part 70 detects the amount of the clothing being put to cylinder 1 according to the difference of the position of the above-below direction of the axle of the such as damper 14 detected by cloth amount test section 15.
Then, control part 70 sets the second set point of temperature B based on the amount of the clothing detected by cloth amount test section 15.Specifically, when the amount of the clothing shown in Fig. 5 is few, the second set point of temperature B is set as B2 by control part 70.On the other hand, when the amount of the clothing shown in Fig. 4 is many, the second set point of temperature B is set as B1 by control part 70.
That is, as shown in Figure 5, when the amount of clothing is few, the index of aridity is short during reaching 90%, 100%.In addition, because clothing is few, therefore for the temperature of the drying air detected by discharge temperature test section 72, there is the tendency uprised in the temperature of glass pane 36.This is caused by the relation between the thermal capacity of drying air and the thermal capacity of clothing.That is, be that if clothing is dry, then the temperature of drying air also can not decline due to the clothing rapid draing when the amount of clothing is few, therefore further heated glazing 36 and glass pane 36 temperature is uprised.
Therefore, control part 70 is below the first set point of temperature A to make the temperature of glass pane 36, and the second set point of temperature B of discharge temperature test section 72 is set as B2<B1.That is, the amount as the clothing of dry object is fewer, and the second set point of temperature B that the detected temperatures based on discharge temperature test section 72 sets sets lower by control part 70.
Another example according to the present embodiment, can optimize based on the second set point of temperature B of the amount of the clothing as dry object using the judgment standard of the temperature as glass pane 36.Now, as shown in Figure 4, when the amount of clothing is many, being set by the second set point of temperature B high is B1.Thus, in drying process, can suppress to reach the second set point of temperature B during clothing easily produces the dry mid-term stage of fold, thus drying air can be made effectively to blow to clothing to suppress uneven drying.In addition, the higher drying air of the wind speed of suppression clothing fold can be made to continue to blow out and long-time lasting and contact with clothing from second blow-off outlet 10 in the second air channel 11.
On the other hand, as shown in Figure 5, when the amount of clothing is few, being set by the second set point of temperature B low is B2.Thereby, it is possible under the state that the temperature of glass pane 36 is remained on below the first set point of temperature A, during the dry ending phase of drying process, be blown into the drying air of Wind Volume from first blow-off outlet 8 in the first air channel 9.
That is, in drying process, the second set point of temperature B correspondingly set based on the amount with clothing controls air channel switching part 12, switches the first air channel 9 and the second air channel 11, the generation of uneven drying and fold can be reduced thus, and can power saving be realized.
In addition, the amount of nothing to do with clothing is how many and the second set point of temperature B and the amount of such as maximum clothing be set as compared with the situation of fixing accordingly, can and the amount of clothing correspondingly between the dry period of the best, the first air channel 9 and the second air channel 11 are switched.Consequently, total power consumption can be suppressed, and the uneven drying of clothing can be eliminated.In addition, the fold of clothing can be suppressed and realize good cloth drying effect.
