In the embodiment of here describing and illustrate in the drawings, cylinder 4 has cylindrical shape and is substantially flatly placed.Therefore, roller height L
dthe line of front side 52 that longitudinally extends to cylinder 4 with the bottom 4a along cylinder 4 from the rear side 51 of cylinder 4 is corresponding.
More at large, the cleaning-drum of washing machine comprises having the middle body of cylindrical shape substantially, but the front side of cleaning-drum and/or rear side can preferably have with respect to middle body the size reducing.Cleaning-drum thereby be preferably essentially horizontally placed in bucket.Therefore, in general, as limited before, roller height L
dwith the line longitudinally extending along the middle body of cylinder corresponding, this line is preferably essentially level.
Therefore, if liquid level L is less than roller height L
d(step 142), water is introduced into the inside (step 143) of bucket 3.
Water is advantageously by being supplied in bucket 3 its flow through drawer 6 and the supply pipe 9 of flowing through.
If liquid level L is higher than roller height L
d(step 144), liquid is discharged to outside (step 145).
Liquid is advantageously by outlet pipeline 25---preferably, if by starting draining pump 26 and driving two-way valve 35(to be set up) and to allow by the mode of outlet pipe 28 drainings---be expelled to outside.
Liquid level L is advantageously sensed by pressure sensor 19.In another embodiment, liquid level L can---such as mechanical sensor, electromechanical sensor, optical sensor etc.---carry out sensing by different level sensors.
In the step (step 142 is to 145) of describing before, therefore the method provides liquid level control and makes the liquid level L of bucket in 3 remain on that liquid touches cylinder 4 substantially from outside but the roller height L that substantially can not enter the inside of cylinder 4
dplace.
Must be noted that, at described liquid level control period, a certain amount of liquid or heated liquid can enter the inside of cylinder 4.This can be for example owing to inevitably controlling reaction time and/or mobile the causing slightly due to cylinder 4 and/or bucket 3.For example, but can enter cylinder 4 described a certain amount of liquid inner and that clothing is soaked is considerably less amount, can enter several millimeters.In addition, the duration of described a small amount of liquid moistened garment is also the short time.Therefore, can suppose that liquid substantially touches cylinder 4 but substantially can not enter cylinder 4 inside from outside.
In follow-up step (step 146), if heat time heating time t
hbe less than predetermined t heat time heating time
p, washing procedure turns back to the liquid level control of being carried out by the step of describing before (step 142 is to 145).
As t heat time heating time
hreach predetermined t heat time heating time
pwhen (step 146 is output as "No"), heating element heater 20 is closed (step 147) and the heating period finishes.
Therefore, the heating period described above (step 140) is carried out predetermined t heat time heating time
p.
However,, in other embodiment, the duration of heating period still can be determined in a different manner.For example, when sense bucket 3 interior liquid temperature T
lreach predetermined heating-up temperature T
lhtime or reach predetermined average heating-up temperature T when the mean value of temperature of the bucket 3 interior liquid that sense
lahtime, the heating period can finish.In addition, when clothing temperature T
lreach predetermined clothing heating-up temperature T
lhor predetermined average clothing temperature T
lahtime, the heating period can finish.Clothing temperature T
lcan be by applicable sensor---for example infrared sensor---sensing or can be in other parameters by control module 22---fluid temperature T of for example sensing
land the weight D of clothing 10
w---basis on the value estimated.
During the heating period described above (step 140), remain on roller height L
dplace heated liquid touch cylinder 4 bottom 4a bottom part and conduct thermal energy transfer to cylinder 4 by heat.Heated cylinder 4 is the clothing 10 to cylinder 4 inside by thermal energy transfer again.
Advantageously, the middle body of cylindrical shape is heated substantially along it for cylinder 4.More advantageously, along it from rear side 51, the whole length to front side 52 is heated cylinder 4.
By this mode, the periphery that clothing 10 touches cylinder 4 from it little by little and is equably heated towards its central authorities.
Should be noted that, the described clothing heating effect obtaining with respect to the thermal energy transfer using by cylinder 4, a small amount of liquid that can enter cylinder 4 inside and moistened garment at liquid level control period as previously described has negligible clothing heating effect.
As shown in Figure 4, in the heating period (step 140), also preferably carry out one or more swing circle (step 150) of cylinder 4, thereby promote the homogeneous heating of cylinder 4 and then clothing 10.
In a preferred embodiment, preferably under the slow-speed of revolution between 80rpm, carry out continuous rotation to be for example included in about 10rpm.
In other embodiment, preferably for example, under low speed (approximately 10rpm between 80rpm) with regular time interval carry out continuous swing circle, this has the above-mentioned same advantage of mentioning.
The heat transmission of heat energy from heater 20 to clothing 10 allows to reduce heat loss with respect to prior art.In fact, the heat energy of heated liquid is directly passed to cylinder 4 and is passed to clothing 10 from cylinder 4, thereby avoided consuming in other pipelines of washing machine 1, for example heating period regulation use recirculating line make the known method of heated liquid recirculation in along recirculating line generation heat loss.In addition, make liquid level L remain on roller height L
dcontrol avoided liquid to enter the inside of cylinder 4.By this mode, advantageously maintain the first amount Q1 of the water W reaching in aforementioned stages
wwith dry weight D

Must be noted that particularly the liquid of minute quantity can enter in bucket 3 due to slightly the moving of cylinder 4 during the rotation at cylinder 4 and/or bucket 3.However, as previously discussed, the liquid that enters this minute quantity conventionally being absorbed by clothing 10 of cylinder 4 inside still can not change the best ratio Q1 of expectation substantially
w/ D
w.
In addition,, with respect to the heating period of known technology, the heating period (step 140) of this method advantageously realizes with the kinetic equation loss reducing.In fact the energy, using during the heating period of this method is almost all consumed for the height of the bottom to being positioned at bucket 3 to roller height L
dthe liquid of described amount heat.
In contrast, in the method that belongs to prior art of mentioning, energy is used to the more substantial water around cleaning-drum to heat, and is used in particular for exceeding roller height L between fill bucket and cylinder
