With reference to Fig. 6, if beginning hot blast washing stroke, control part 40 (step e 1) after the timing of the device 51 that picks up counting then, the two is switched on to 2 drying heaters 34, thus, grade with " by force " drives drying heater 34, from the internal feed hot blast (step e 2) of dry component 3 to water jacket 7.
Then, control part 40 is according to the input signal from temperature sensor in the groove 63, monitor the temperature of the air in the water jacket 7 whether be less than 70 ℃ set point of temperature (such as, 60 ℃) (step e 3).In addition, if the temperature of the air in the water jacket 7 arrives afore mentioned rules temperature (in step e 3, being "Yes"), control part 40 is by stopping one energising in 2 drying heaters 34, with the grade of " weak ", drive drying heater 34 (step e 4), the rotation (step e 5) of beginning cylinder 10.
Then, cylinder 10 is by the control of control part 40, carry out repeatedly such as, just change according to the speed of per 10 seconds 60rpm, then, stop 3 seconds, then, according to the speed counter-rotating of per 10 seconds 60rpm, the action that stops 3 seconds repeatedly once more.Thus, the washed of water that comprises by the hot blast heating supplied with from dry component 3 rolled.
In this distortion example, in the hot blast washing stroke, with the rotary speed that is higher than the cylinder 10 of laundry in the stroke (such as, rotary speed 45rpm) (such as, 60rpm), make cylinder 10 rotations.The relation of the torque when making cylinder 10 rotation, in the hot blast washing stroke, have to be higher than the rotary speed of the occasion in the laundry stroke, the situation that the power consumption of the occasion of cylinder 10 rotation is reduced is in such occasion, by like this, the rotary speed of the cylinder 10 in the hot blast washing stroke is higher than the occasion in the laundry stroke, thus, electric power that can be still less carries out the hot blast washing stroke.
Washed in making cylinder 10 roll during, control part 40 is according to the input signal from temperature sensor in the groove 63, whether the temperature that monitors the air in the water jacket 7 reaches 70 ℃ (step e 6), by timer 51, whether monitor beginning from the hot blast washing stroke through 10 minutes (step e 8).
The temperature of the air in water jacket 7 does not reach 70 ℃, from beginning through 10 minutes of hot blast washing stroke (in step e 8, be "Yes"), then control part 40 stops drying heater 34 (step e 9), stop the rotation (step e 10) of cylinder 10, stop the timing (step e 11) of timer 51, finish the hot blast washing stroke.
On the other hand, the temperature of the air in water jacket 7 reaches 70 ℃ occasion (in step e 6, being "Yes"), though then control part 40 from the hot blast washing stroke begin through 10 minutes before situation under, still stop drying heater 34 (step e 7).Even in this case, control part 40 still carries out the rotation control of cylinder 10, until beginning through 10 minutes from the hot blast washing stroke (until in step e 8, be "Yes"), in the moment (, being "Yes") of beginning from the hot blast washing stroke, stop the rotation (step e 10) of cylinder 10 in step e 8 through 10 minutes, stop the timing (step e 11) of timer 51, finish the hot blast washing stroke.Thus, can prevent that the temperature of the air in the water jacket 7 is too high, the situation that security suffers damage.
In this distortion example, beginning from the hot blast washing stroke, after the stipulated time (time the when temperature of the air in the water jacket 7 reaches the afore mentioned rules temperature), make cylinder 10 rotations.Therefore, the water heating with being included in washed after the draining at the state that cleaning strength improves, makes cylinder 10 rotations, carry out hot blast washing, thus, when beginning in supply to the hot blast of water jacket 7, the scheme of cylinder 10 rotation is compared, and electric power that can be still less improves cleaning strength.
When the running of tumbling-box washing machine 1 begins, make the 10 rotation stipulated times of cylinder, at this moment, if according to input signal from current detection circuit 50, amperometric determination portion 47 by control part 40, measure the drive current of motor 12, then can detect the washed amount (load) of cylinder 10 inside according to the drive current of having measured.In the bigger occasion of washed load, because the water that is included in (the step S3 of Fig. 4) after the draining washed is more, so will being included in water in washed, to be heated to the needed heat of uniform temperature more, in the less occasion of washed load, because the water that is included in washed after the draining is less, to be heated to the needed heat of uniform temperature less so will be included in water in washed.
So, if constitute in the following manner, this mode is: in the bigger occasion of washed load, the temperature of the hot blast that feeds to water jacket 7 inside in the hot blast washing stroke is risen, perhaps, prolongation feeds to hot blast the time of water jacket 7 inside in the hot blast washing stroke, on the other hand, in the less occasion of washed load, the temperature of the hot blast that feeds to water jacket 7 inside in the hot blast washing stroke is descended, perhaps, shortening feeds to hot blast the time of water jacket 7 inside in the hot blast washing stroke, then the water temperature that can be fit to heats the water that is included in washed after the draining, thus, electric power that can be still less improves cleaning strength.
In addition, by the cooling-water temperature sensor 62 detected lower occasions of temperature that are stored in the water in the water jacket 7, because it is also lower to be included in the temperature of the water in (the step S3 of Fig. 4) after the draining washed, so will being included in water in washed, to be heated to the needed heat of uniform temperature more, the higher occasion of temperature at the water of the inside that is stored in water jacket 7, because it is also higher to be included in the temperature of the water in washed after the draining, to be heated to the needed heat of uniform temperature less so will be included in water in washed.
So, if constitute in the following manner, this mode is: the occasion that the temperature of the water in being stored in water jacket 7 is lower, the temperature that feeds to the hot blast in the water jacket 7 in the hot blast washing stroke is risen, perhaps prolong the time that in the hot blast washing stroke, hot blast is fed to the inside of water jacket 7, on the other hand, the occasion that the temperature of the water in being stored in water jacket 7 is higher, the temperature that feeds to the hot blast in the water jacket 7 in the hot blast washing stroke is descended, perhaps shorten the time that in the hot blast washing stroke, hot blast is fed to the inside of water jacket 7, then the heat that can be fit to, the water that is included in the washings after the draining is heated, thus, electric power that can be still less improves cleaning strength.
