At first, when requiring washing procedure by the user, the controller (not shown) that constitutes a washing machine part is supplied with washings (S510) to washtub 120.
At this moment, supplying with in the process of washings by washings supply pipe 113, washings are through the detergent box 114 on the pipeline that is installed in washings supply pipe 113.
Because the washing agent of scheduled volume is contained in the detergent box 114, the washings that infeed washtub 120 have comprised the washing agent that is stored in the detergent box 114.
Especially, in above-mentioned washings supply program, the control washings make it be in the high concentration state.
This is to realize by the water level that keeps washing water supplied, make the water level of washing water supplied be lower than predetermined water level according to the predefined washings of laundry amount, but the lower surface that is higher than cylinder 130, and especially, the water level of washing water supplied is to make washings heater 122 approximately be immersed in the height in the washings, as shown in Figure 7.
At this moment, most preferably, the water level of washing water supplied is to make the lower surface of cylinder 130 approximately be immersed in the height in the washings, promptly is the height (" first water level ") that makes that laundry item in the cylinder 130 soaks.
After above-mentioned water supply program was finished, head roll 130 made it possible to utilize the high concentration washings of supply to carry out washing procedure (hereinafter referred to as " high concentration washing procedure ") (S520).
High concentration washing procedure above-mentioned is to make the maximized program of detersive efficiency.
Especially, consider the fact that scourability improves owing to the increase of detergent concentration, wherein the concentration of washing agent is one of principal element that influences scourability, can realize remarkable scourability by above-mentioned high concentration washing procedure.
At this moment, can control the high concentration washing procedure that is undertaken by head roll, make the high concentration washing procedure to supply with program and side by side carry out with above-mentioned washings.
In addition, at this moment, more preferably the Control Circulation pump 160, make that the washings in the washtub 120 can be recycled into cylinder 130 (S530) by circulation canal 170 then by circulating pump 160 suctions.
This is because when carrying out the high concentration washing procedure, and the high concentration washings can be ejected into the laundry item in the cylinder 130, and therefore can realize the even washing of all laundry items.
Certainly, can carry out control operation, make the washings cyclic program to supply with program with washings and side by side carry out, perhaps making washings supply with program, high concentration washing procedure and washings cyclic program can side by side carry out.
Therefore on the other hand, during above-mentioned high concentration washing procedure, can control the steam feed unit and make high-temperature steam can spray into cylinder 130, and the internal temperature of cylinder 130 can remain on and makes scourability increase maximum optimal temperature levels.
Especially, the internal temperature of cylinder remains on optimal temperature levels (about 40 ℃ to 60 ℃), realizes the most effective scourability at this temperature levels by the washing agent that is activated by high-temperature steam, and therefore improves detersive efficiency.
Certainly, can carry out control operation, making steam supply program to supply with program with washings side by side carries out, making steam supply with program can side by side carry out with the washings cyclic program, makes that perhaps steam is supplied with program, program supplied with by washings and the washings cyclic program can side by side be carried out.
After above-mentioned high concentration washing procedure had carried out one period scheduled time, control steam feed unit made high-temperature steam can spray into cylinder 130 (S540).
The reason that high-temperature steam sprays into cylinder is for the internal temperature with cylinder 130 increases to sterilisation temp, the various bacterium that makes it possible to comprise in sterilisation temp is killed laundry item.
Certainly, though head roll 130 continuously still at this moment, and therefore carry out high concentration disinfecting cleaning program (S550) continuously.This state is shown in Figure 8.
Especially, can control above-mentioned steam jet program, make the steam jet program during high concentration disinfecting cleaning program, to carry out continuously.Yet in this case, the quantity of steam that infeeds cylinder 130 may increase excessively, and perhaps the internal temperature of cylinder 130 may increase excessively, thereby energy consumption correspondingly increases.
Based on this reason, most preferably control the steam jet program, make the steam jet program only in predetermined temperature range and in one period scheduled time, to carry out.
Here, predetermined temperature range is the temperature range of possible kill bacteria, and one period scheduled time is a period of time of possible kill bacteria, and therefore can obtain optimum Disinfection Effect.
Control steam jet program makes the control method that the steam jet program can be only carried out in predetermined temperature range and in one period scheduled time, carry out by the operation that repeatedly moves the steam feed unit and interrupt the steam feed unit.
Especially, optionally connect and cut off the power supply of the heating operation that is used to control heating part 210, thereby the internal temperature of cylinder 130 remains in the predetermined temperature range.
At this moment, confirm temperature by reading the signal that detects by temperature sensor 150.
Therefore, by said procedure, sequentially carry out high concentration washing procedure and disinfecting cleaning program.
After finishing high concentration washing procedure and disinfecting cleaning program, further supply with washings (S560) to washtub 120.
At this moment, the washings that infeed washtub 120 do not comprise washing agent.Further supply with washings, reach according to the predefined predetermined water level of laundry amount (" second water level ") up to washings.This state is shown in Figure 9.
Said procedure is to be used to dilute the program that is included in the high concentration detergent in the laundry item, because being extended time ground, laundry item is exposed to the infringement that high concentration detergent causes in order to prevent to laundry item, and for high concentration detergent is rinsed out from laundry item.
In addition, index drum 130 makes during said procedure head roll 130 continuously.
Therefore, dilute washing procedure, make it possible to successfully from laundry item, remove high concentration detergent (S570).
Especially, consider that the various dirt that separates is included in the fact in the high concentration detergent from laundry item, also successfully from laundry item, removed dirt.
On the other hand, consider during dilution washing procedure by further supply washings, further the temperature of washing water supplied is approximately 30 ℃ or lower, make the temperature of whole washings drop to below the best wash temperature by mixing existing washings with further washing water supplied, best wash temperature realizes best scourability, for example is 40 ℃ or lower.
Therefore, most preferably during dilution washing procedure by further supply washings, washings heater 122 in the operation washtub 120, make it possible to by the washings in the washings heater 122 heated scrub buckets 120, and therefore, all the temperature of washings can remain on about 40 ℃ or higher.
Certainly, can carry out control operation, make high-temperature steam spray into cylinder 130 and heated scrub water directly not, and therefore, the internal temperature of washtub 130 reach the best wash temperature that scourability is improved.
Especially, more preferably the Control Circulation pump 160, make at said procedure, promptly during the dilution washing procedure by further supply washings, washings in the washtub 120 can be aspirated by circulating pump 160, and can supply with to cylinder 130 by circulation canal 170 subsequently.
This is because can successfully remove high concentration detergent from laundry item, and therefore, can realize the even washing of all laundry items.
Carrying out above-mentioned dilution washing procedure after one period scheduled time, finish the washing operation of laundry item, and stop to produce heat by washings heater 122, stop to drive circulating pump 160, stop head roll 130.
After finishing above-mentioned washing operation, the washings in the washtub 120 are discharged by drainage pipeline 121, carry out at least rinsing operation by supplying with new washings then.
Certainly, preferably after discharging washings and carry out before the rinsing operation, further comprise high speed swing roller 130 in order to from laundry item except that the program of anhydrating.
Now, the washing methods of the washing machine of another preferred embodiment according to the present invention will be described in detail.
As shown in Figure 6, when requiring washing procedure by the user, the controller (not shown) control steam feed unit that constitutes a washing machine part is supplied with high-temperature steam (S610) to cylinder 130.
As a result, high-temperature steam is got the laundry item in the cylinder 130 wet, and in addition, the internal temperature of cylinder 130 reaches the optimal temperature levels that maximization realizes scourability.
Especially, the internal temperature of cylinder 130 reaches the optimal temperature levels that maximization realizes scourability by high-temperature steam, and therefore improves detersive efficiency.
At this moment, temperature is 40 ℃ or higher.Preferably, temperature is between 40 ℃ to 80 ℃.
