Be provided with aridity test section 9 in the mode of facing in the swing roller 3 near below air supply opening 8.Aridity test section 9 is by contacting the resistance value that detects this clothing etc. with the clothing that is stirred etc. in swing roller 3, thereby detect the aridity of clothing etc.As shown in Figure 3, aridity test section 9 is by 2 electrode 9A be used to keep the insulating component 9B of electric insulation between electrode 9A to constitute.Aridity test section 9 is used to detect the resistance value that strides across clothing of contacting with these 2 electrode 9A between 2 electrode 9A etc.
Rotating speed test section 10 is used to detect the rotating speed (rotating cycle of unit interval) of swing roller 3.As shown in Figure 4, rotating speed test section 10 is made of with the reed switch 10B of relative configuration with magnetic 10A the magnetic 10A that is located at swing roller 3.Output signal and rotating speed test section 10 that the resistance value of the detection clothing of aridity test section 9 etc. obtains utilize the output signal of detected expression swing roller 3 rotating speeds of reed switch 10B to be transfused to control part 11.In addition, rotating speed test section 10 is not limited to this structure, for example also can detect the rotating speed of swing roller 3 photographically.
As Fig. 2, shown in Figure 5, circulation wind path 18 is communicated with swing roller, and the dry air of using is at internal circulation.The radiator 14 of heat pump assembly 12 and heat dump 16 are equipped in the circulation wind path 18, and this circulation wind path 18 is used for importing the drying air of being carried by blower fan 6 in swing roller 3.Air dewetting is resultful to drying before drying is heated with air.Therefore, radiator 14 and heat dump 16 be located in the circulation wind path and heat dump 16 is located at (upstream side) before the radiator 14 on the dry direction that flows with air, thereby can dehumidify with air drying.
The downstream of the radiator 14 in circulation wind path 18 is provided with and is used to detect the temperature detecting part 19 that the drying that imports to swing roller 3 is used the temperature of air.In addition, blower fan 6 sucks air in the swing roller 3 from the exhaust outlet (not shown) of the rear side of being located at swing roller 3 to circulation wind path 18.In addition, blower fan 6 also can adopt electric fan etc. to be formed in the circulation wind path 18.
Below, action, the effect of the clothesdrier that constitutes as described above are described.The user opens door 4, in swing roller 3, put into the clothing of wanting dry etc., when the beginning dry operating, motor 2 drives swing roller 3 and blower fan 6, and the compressor 13 of heat pump assembly 12 also is driven, and makes the rotating speed action to set separately respectively of this swing roller 3, blower fan 6 and compressor 13.Rotating speed test section 10 detects the rotating speed of swing roller 3 as described above.Control part 11 is controlled to the rotating speed of swing roller 3 the 1st rotating speed r1 (for example 50rpm) of regulation based on the output of rotating speed test section 10.
Lug, nib 7 lifts the clothing in the swing roller 3 etc., makes clothing etc. fall and stir from the height of regulation.Blower fan 6 is supplied with the hot blast of doing, and carries out the drying of clothing etc. thus.The temperature of hot blast is detected by temperature detecting part 19, and control part 11 is controlled temperature setting portion 20 based on the output of temperature detecting part 19, and the temperature of hot blast is controlled to predefined temperature (for example 70 ℃).Clothing in swing roller 3 etc. is stirred and when contacting with aridity test section 9, and aridity test section 9 detects the resistance value that strides across the clothing that contact with these 2 electrode 9A between 2 electrode 9A etc., thus the aridity of detection clothing etc.
Fig. 6 is the action time figure of this clothesdrier of expression.Particularly, under less situation such as the amount of the clothing of putting into etc., the action of changing in time of Y and swing roller 3, compressor 13, blower fan 6 etc. is promptly counted in expression less than the number of times of the value of regulation by the resistance value of aridity test section 9 detected clothing etc. in the unit interval.Counting Y for example represents that inner drying degree test section 9 detected resistance values are less than the number of times of the value of regulation during 10 seconds.The value of this regulation for example is set to 5M Ω.
Under less situation such as the amount of the clothing that is placed into etc., the clothing that is lifted by lug, nib 7 with the 1st rotating speed r1 etc. with by lug, nib 7 from the state rotation of below supporting and do not fall, thereby contact drying degree test section 9 not.Therefore, during the 1st stipulated time T1 that begins from dry operating (for example 1 minute), counting Y is 0.
Even through the 1st stipulated time T1, counting Y also is 0 o'clock, and control part 11 makes the rotating speed of swing roller 3 be reduced to the 2nd rotating speed r2 (for example 35rpm) of regulation from the 1st rotating speed r1.Afterwards, during the 2nd stipulated time T2 (for example 2 minutes), detect the resistance value of clothing etc. by aridity test section 9.Drop to the 2nd rotating speed r2 of regulation by the rotating speed of swing roller 3, the centrifugal force of the clothing that is supported by lug, nib 7 from the below etc. dies down, and clothing etc. fall and contact drying degree test section 9 from the height of regulation.
The clothing of beginning dry operating after through the 1st stipulated time T1 etc. is to contain the more wet state of moisture, and aridity test section 9 detects the resistance value littler than the resistance value of dry status.Therefore, littler than the value of regulation by the resistance value of aridity test section 9 detected clothings etc. during the 2nd stipulated time T2, counting Y is not 0.Then, continue dry operating, clothing etc. is being carried out dry moment t1, counting Y is 0 once more.At moment t1, control part 11 calculates remaining dry operating time T 3 according to the moment t1 that maximum y2 that counts Y and Y are 0.That is,, be T3, so control part 11 can be set the time of drying such as continuations that make clothing by dry easy degree, amounts of moisture such as t1 identification clothings owing to can detect the amount of clothing etc. by y2.
When control part 11 becomes moment t2 having passed through dry operating time T 3, stop the action of the compressor 13 of heat pump assembly 12.Afterwards, make the action of swing roller 3 and blower fan 6 extend to moment t3 and finish dry operating.In addition, so-called clothing etc., being included in the swing roller 3 can dry fibre, is not limited to clothing.
Like this, control part 11 utilizes aridity test section 9 to continue the resistance value of the 1st stipulated time T1 ground detection clothing etc. from begin dry operating with the 1st rotating speed r1.In the time of can't detecting the resistance value more than the value that only detects regulation than the little resistance value of stipulating of value during this period, control part 11 makes swing roller 3 be reduced to the 2nd rotating speed r2.Afterwards, control part 11 utilizes aridity test section 9 to continue the resistance value of the 2nd stipulated time T2 ground detection clothings etc.According to the control of such rotating speed, can make be in the lug, nib 7 that is rotated cylinder 3 from the state of below supporting down the clothing etc. of rotation fall to the bottom direction of swing roller 3 from the position of the regulation lifted by lug, nib 7.Therefore, can contact with aridity test section 9 by making clothing etc., aridity test section 9 detects the resistance value of clothings etc.Therefore, even control part 11 also can detect aridity accurately under the situation of a spot of clothing of drying etc., clothesdrier can not can produce over-drying and drying drying clothes etc. best insufficiently.
But, during the 1st stipulated time T1, be under 0 the situation at counting Y, it is generally acknowledged any following situation.
(1) swing roller 3 is empty.
(2) only put into dried clothing etc. in the swing roller 3.
(3) it is less to put into the amount of clothing etc. of swing roller 3, and wet clothing etc. does not contact with aridity test section 9.
Therefore, control part 11 makes swing roller 3 be reduced to the 2nd rotating speed r2, utilizes aridity test section 9 to continue the resistance value of the 2nd stipulated time T2 ground detection clothings etc.At this constantly, if detect aridity test section 9 for the time, can infer that then the clothing that wets etc. puts into swing roller 3 but the less situation of amount of this clothing etc. than the little resistance value of the value of regulation.
Detected resistance value in this wise than the little situation of the value of regulation under, preferred control part 11 utilizes temperature setting portion 20 that drying is reduced to the 2nd temperature t h2 (for example 50 ℃) and turns round from the 1st temperature t h1 (for example 70 ℃) with the temperature of air.By this control, control part 11 can detect the aridity under the situation of dry a spot of clothing etc., dry this clothing in power consumption ground when reducing dry operating etc. accurately.Particularly, for example, reduce the running of output ground as long as be reduced to the 2nd rotating speed R2 (for example 30r/s) from the 1st rotating speed R1 (for example 60r/s) by the rotating speed that makes compressor 13.
In addition, the value that is used for the regulation that the value of regulation that the resistance value that is detected is judged and being used for judges the resistance value that is detected during the 1st stipulated time T1 during the 2nd stipulated time T2 both can be the same or different.
As present embodiment, have heat pump assembly 12, radiator 14 as under the situation of heating part, can be reduced and reduce output, the dry temperature with air of reduction by the rotating speed that makes compressor 13.Replace, using under the situation of heater as the heating part, as long as reduce the energising electric power of heater.In addition, under the situation of using heater, also can not be provided with circulation wind path 18.That is, also the control of present embodiment can be applied to clothesdrier in the past with Figure 10 explanation.
In addition, in the above-mentioned control of control part 11, the 2nd stipulated time T2 that preferably will detect the resistance value of clothing etc. sets to such an extent that be longer than the 1st stipulated time T1.According to such setting, can be increased in the chance that the clothing that is stirred in the swing roller 3 and falls etc. contacts with aridity test section 9, can improve the precision of the aridity that detects a spot of clothing etc.
(embodiment 2)
Fig. 7 is the time diagram of action of the clothesdrier of expression embodiments of the present invention 2.The basic structure of the clothesdrier of present embodiment is identical with embodiment 1 with the part of control.That is, control part 11 utilizes aridity test section 9 to continue the resistance value that the 1st stipulated time T1 detects clothing etc. (for example 1 minute) from the beginning dry operating.When this period, aridity test section 9 did not detect the little resistance value of value than regulation, control part 11 made swing roller 3 be reduced to the rotating speed r2 of regulation.That is, be 0 o'clock at the counting Y of the 1st stipulated time T1 inner drying degree test section 9, control part 11 makes swing roller 3 be reduced to the rotating speed r2 of regulation.
In the clothesdrier of present embodiment, afterwards, control part 11 utilizes aridity test section 9 to continue the resistance value that the 2nd stipulated time T2 ground detect clothings etc., and during than the little situation of the value of stipulating, control part 11 stops the action of heat pump assembly 12 in the resistance value that does not detect clothing etc.That is, the counting Y of aridity test section 9 is 0 o'clock during the 2nd stipulated time T2, and control part 11 stops the action of heat pump assembly 12.
That is, the counting Y of aridity test section 9 is 0 o'clock during the 2nd stipulated time T2, and control part 11 detected situations are, clothing etc. be dry or swing roller 3 in be empty.Then, thus control part 11 makes after through the 2nd stipulated time T2 the action of swing roller 3 and blower fan 6 stop to finish dry operating with heat pump assembly 12.
According to said structure, the drying that can detect accurately under the situation of dry a spot of clothing etc. finishes, and prevents over-drying ground such as clothing and the damage fiber is eliminated the waste of electric power.Maybe can prevent to continue dry run.
In this case, the value that is used for the regulation that the value of regulation that the resistance value that is detected is judged and being used for judges the resistance value that is detected during the 1st stipulated time T1 during the 2nd stipulated time T2 also is both to can be the same or different.
(embodiment 3)
Fig. 8 is the major part cutaway view of the clothesdrier of embodiments of the present invention 3.The control of the clothesdrier of present embodiment is identical with embodiment 1 or embodiment 2.The clothesdrier of present embodiment is characterised in that, aridity test section 9 is provided near the bottom the periphery of peristome 5 of the front surface side of being located at swing roller 3, carries the drying air towards aridity test section 9 from the air supply opening 8 of the rear side of being located at swing roller 3.
The low mode in high back tilts before the rotating shaft 3A of swing roller 3, and swing roller 3 can be incorporated in the housing 1 rotatably.The angle of inclination of rotating shaft 3A is made as about 20～30 degree.Rear side at swing roller 3 is provided with air supply opening 8, is provided with exhaust outlet 21 below the peristome 5 of the front surface side of swing roller 3.The drying that is discharged from from exhaust outlet 21 circulates to swing roller 3 from air supply opening 8 by circulation wind path 18 with air.The drying of the low temperature that contacts with clothing etc. in swing roller 3 and wet enters into circulation wind path 18 with air from exhaust outlet 21, arrives heat dumps 16 by lint filter (lint filter) 22.
The drying that has wet is become dried air with air by heat dump 16 cooling and dehumidifyings, heated by radiator 14 and become dried hot blast, supply with to swing roller 3 from air supply opening 8, then, near the aridity test section 9 of the bottom the periphery that is provided in peristome 5 is transferred.Other structure is identical with embodiment 1, to the identical Reference numeral of structure mark of the performance effect identical with embodiment 1, omission specific description.
When the low mode in high back tilted before making swing roller 3 in this wise, the user can be easily takes out the clothing etc. of the bottom that is positioned at swing roller 3 from peristome 5, improves ease of use.Yet the clothing isogonic that is stirred in swing roller 3 falls to rear side, is difficult to contact with the aridity test section 9 of the below of the peristome 5 of being located at the front surface side.That is, detecting the aridity of a spot of clothing etc. accurately improves ease of use with easily taking out clothing etc. the two is a contradiction.
To this, in above-mentioned structure, the drying of being carried by blower fan 6 can be sent the clothing that is stirred etc. with air in swing roller 3 to the front surface thruster that is provided with aridity test section 9.Therefore, the clothing that falls etc. contacts reliably with aridity test section 9.Therefore, can make the clothing that is rotated from the state of below supporting with the lug, nib 7 that is rotated cylinder 3 etc. not can from the position deflection rear side of the regulation lifted by lug, nib 7 fall, can contact with aridity test section 9 and detect the resistance value of clothing etc.Its result not only can easily take out clothing etc., and the aridity can detect dry a spot of clothing etc. accurately time the and can be not over-drying and drying drying clothes etc. best insufficiently.
