Besides the circulation path of bright warm braw.In Fig. 1, the extraneous air that the suction hole 22 that forms via the bottom of shell 1 is sucked becomes warm braw through heater 4 and air blast 5, and warm braw blows out top peristome through nozzle 27 guiding washing and dewatering buckets 15 from flexible pipe 3.Then, the warm braw utilization because of washing and dewatering bucket 15 with contact with washings 18 with diffusion effect that the turning effort of the impeller 19 of 15 rotations of washing and dewatering bucket causes and evaporate moisture content.Thus, moist warm braw or extract out or extract out from dewatering hole 17 to the outer bottom of washing and dewatering bucket 15 from impeller passage 28 is discharged upward by the lower space of outer bucket 2 and washing and dewatering bucket 15.And the warm braw that moisture is big spreads to the outside through steam vent 23 from blast pipe 24.In addition, the suitable value of setting space distance makes the pressure loss maximum of top spatial portion of the following and balancer 16 of splash guard 6.Such heated airflow path also is the same for embodiment 2～7.
In addition, Fig. 2 is that expression is from being located at outside barrels 2 and the figure of an example of the variations in temperature of the warm braw that obtains of the Temperature Detector 25 of the upper space of washing and dewatering bucket 15.In Fig. 2, whole process by drying begin the warming up period (the A line among Fig. 2) that slowly rises of temperature of back warm braw, after this tail off rising stage (the C line among Fig. 2) of temperature rising of temperature stabilization stationary phase (the B line among Fig. 2) of getting off and further dry back washings institute water content is formed.In the process of rising stage,, for example can select the absolute value of serviceability temperature or the variable quantity of initial temperature relatively for the determinating reference of the degree of drying of washings 18 described later.This situation also is the same in embodiment 2～12.
Fig. 3 is the block diagram of the structure of expression control part 20.This block diagram also is the same for embodiment 2,3.In Fig. 3, the 30th, control the 1st impeller control part that motor left rotation and right rotation device 31 makes impeller 19 left rotation and right rotation according to the setting-up time of timer 32.The 26th, the revolution detector of the rotation number of detection motor 7, the 33rd, be used for the rotary driving force of motor 7 is sent to the clutch action device of washing and dewatering bucket 15, the 34th, make motor 7 dextrorotary motor right-hand rotation devices, the 35th, in control clutch action device 33 according to the 1st barrel of control part of the output control motor right-hand rotation device 34 of revolution detector 26.The 36th, according to the 1st central control part of the output of Temperature Detector 25 control heater 4, air blast the 5, the 1st impeller control part 30 and the 1st barrel of control part 35.
Fig. 4 is the flow chart of the handling process of expression control part 20.Below, the limit is with reference to the action of the scrubbing-and-drying unit of Fig. 4 limit explanation embodiment 1.In the laundry processes of scrubbing-and-drying unit with wash the clothing process and enter dehydration (after the step S100) after being over.And after dehydration is over (step S100), be that washings 18 has been attached to after the inwall of washing and dewatering bucket 15, enter dry run (after the step S200), so warm braw blows out from flexible pipe 3, through the top peristome of nozzle 27 guiding washing and dewatering buckets 15.This point also is the same to embodiment 2,3.
Then, enter the drying of scattering (step S200), impeller 19 rotated 1 minute so repeatedly with ON0.5 second, OFF0.5 alternately rotation about the cycle of second.So the washings 16 (A among Fig. 1) that has been attached to the inwall of washing and dewatering bucket 15 falls and scatters randomly up and down thereupon, warm braw generally contacts with the washings 18 that scatters (B among Fig. 1).
Then, enter Rotary drying (step S201), after driving clutch action device 33, control the action of motor right-hand rotation device 34 according to the output of revolution detector 26.So, washing and dewatering bucket 15, for example the revolution with 300rpm rotated about 3 minutes.At this moment, utilization makes warm braw contact with the washings that is attached to the inwall of washing and dewatering bucket 15 because of action of centrifugal force (A among Fig. 1) because of the turning effort of washing and dewatering bucket 15 with the diffusion effect that the turning effort of the impeller 19 of washing and dewatering bucket 15 rotations causes.The highest with washings 18 drying efficiencies of the direct contact position of warm braw, this point by experimental result described later (with reference to Figure 10) as can be known.And the circulation path through regulation after washings 18 contained water evaporates spread carries out exhaust.
Then, enter the judgement of degree of drying (step S202), judge the degree of drying of washings 18 according to the output of the Temperature Detector 25 that detects delivery temperature.If the absolute value of Temperature Detector 25 output the or when variable quantity of initial value is under predefined setting relatively, then be judged to be drying not good, promptly be NO.And return the drying of scattering (step S200), carry out and above-mentioned same action.In addition, if the absolute value of Temperature Detector 25 output the or when variable quantity of initial value is on predefined setting relatively, then be judged to be drying good, promptly be YES.So, stopping the running of heater 4, air blast 5 and then motor 7, a series of dry run finishes (step S300) at this point.
According to top structure, because of warm braw generally contacts with washings 18, so can promote the water evaporates diffusion of washings 18.So, can carry out the drying efficiency height of washings 18 and washings 18 and not produce wrinkle and uneven drying, promptly finish the high drying of quality.
Fig. 5 is the flow chart of handling process of the control part 20 of expression scrubbing-and-drying unit another embodiment.Below, the limit is with reference to Fig. 5, and the limit illustrates the action of the scrubbing-and-drying unit of embodiment 2.Because of dehydration (step S100) the 1st scatter drying (step S200), Rotary drying (step S201) afterwards judges that with the 1st degree of drying (step S202) is the same with embodiment 1, so omit its explanation here.When the judgement (step S202) by the 1st degree of drying judge not dry good, when promptly being judged to be NO, returning the 1st drying (step S200) of scattering and carry out and above-mentioned the same action.And when the judgement (S202) by the 1st degree of drying judge dry good, when promptly being YES, then enter the 2nd drying (step S203) of scattering.And alternately rotation about impeller 18 carried out repeatedly with the cycle of ON0.3 second, OFF0.5 second rotates back and forth 1 minute.Thus, make the washings 18 (A among Fig. 1) that on washing and dewatering bucket 15 inwalls, becomes to put up state shake by a small margin and drop on randomly and locate up and down and scatter (B among Fig. 1), and warm braw generally contacts with washings 18.
Secondly, the judgement (step S204) that enters the 2nd degree of drying.And, if the absolute value of the output of Temperature Detector 25 or relatively the variable quantity of initial value under predefined setting, then judge not dry good, promptly be NO.Thus, returning the 2nd drying (step S203) of scattering carries out and above-mentioned the same action.Have, setting that the 1st degree of drying judgement (step S202) is used and the 2nd degree of drying judge that the size of the setting that (step S204) is used is set at the setting of setting＜the 2nd degree of drying of the 1st degree of drying again.In addition, when judging in (step S204) at the 2nd degree of drying, if be judged to be YES, be Temperature Detector 25 output absolute value or when relatively the variable quantity of initial value is on predefined setting, then stop the running of heater 4, air blast 5 and motor 7, finish a series of dry run (step S300).
Because have above structure,, can promote the water evaporates diffusion of washings 18 significantly so warm braw generally contacts more all sidedly with washings 18.Therefore, can carry out the drying efficiency height of washings 18 and washings 18 does not produce wrinkle and drying mark, promptly finishes the very high drying of quality.
Fig. 6 is the flow chart of handling process of the control part 20 of expression scrubbing-and-drying unit another embodiment.Below, the limit is with reference to Fig. 6, and the limit illustrates the action of the scrubbing-and-drying unit of embodiment 3.Because of dehydration (step S100) drying of scattering (step S200) afterwards is the same with embodiment 1, so omit its explanation here.Then, enter the 1st Rotary drying (step S201), washing and dewatering bucket 15, for example the revolution with 100rpm rotated 3 minutes.In the 1st Rotary drying (step S201), the inner bottom part that washings 18 is maintained be laminated in washing and dewatering bucket 15, be to be rotated drying under the top state of impeller 19.The water evaporates characteristic of washings 18 at this moment is (with reference to Fig. 8) shown in the experimental result as described later.Have, the centrifugal force on the known inwall that acts on washing and dewatering bucket 15 under washing and dewatering bucket 15 during with the rotation of the revolution of 100rpm, at the bucket internal diameter is the situation of 45cm approximately is 2.5G again.At this moment, washings 18 is to the some distances of inwall one side shifting of washing and dewatering bucket 15, the cavity of several cm that can form in the upper central portion of impeller 19.
Secondly, enter the 2nd Rotary drying (step S202), washing and dewatering bucket 15, for example the revolution with 300rpm rotated 3 minutes.In the 2nd Rotary drying (step S202),, the state washings 18 that washings 18 all moves to inwall because of the centrifugal force of washing and dewatering bucket 15 from the bottom of washing and dewatering bucket 15 is rotated drying even being close under the state of inwall.The water evaporates characteristic of washings 18 at this moment is (with reference to Figure 10) shown in the experimental result as described later.
Then, enter the judgement (step S203) of degree of drying, judge the degree of drying of washings 18 according to the output of the Temperature Detector 25 that detects delivery temperature.If, the absolute value of the output of Temperature Detector 25 or relatively the variable quantity of initial value under predefined setting, then be judged to be not dry good, promptly be NO.Thus, returning the drying of scattering (step S200) carries out and above-mentioned the same action.In addition, when the absolute value of the output of Temperature Detector 25 or when the variable quantity of initial value is on predefined setting relatively, then be judged to be dry good, promptly be YES.So, stop the running of heater 4, air blast 5 and motor 7, finish a series of dry run (step S300).
