And storage part 90 stores needs the washing water supplied amount when washing washing procedure and rinsing program.At this moment, the washing water yield that is stored is the output corresponding to washing weight.And storage part 90 stores based on the benchmark detergent amount of washing weight with according to the benchmark turbidity of this benchmark detergent amount.
The water level of the washings of washtub 13 inside when supplying water in washing procedure and the rinsing program detects in water level detecting portion 100, and sends testing result to control part 70.
Below, the formation according to the control part 70 of first embodiment of the invention is described.
After i.e. first stipulated time of time point process detergent dissolution time that washing procedure begins, control part 70 control turbidity test sections 20 make it detect a turbidity of washings.When control part 70 receives turbidity of turbidity test section 20 detections, then utilize a turbidity that receives to determine to drop into detergent amount.If turbidity test section 20 is provided with a plurality of turbidity transducers, then control part 70 utilizes the turbidity mean value of the turbidity of the some turbidity transducers that transmit from turbidity test section 20 or a plurality of turbidity transducers and determines detergent amount.
After i.e. first stipulated time of time point process detergent dissolution time that washing procedure begins, control part 70 control turbidity test sections 20, so that the washings turbidity of turbidity test section 20 when detection motor 15 stops each time in the stipulated time of first stipulated time, and calculate average turbidity based on a plurality of nephelometers that detected, obtain turbidity more accurately thus.At this moment, the turbidity of the washings when stopping each time because of detecting motor 15, thus can only detect the washings turbidity of avoiding the error that causes because of current, can obtain turbidity more accurately thus.
More particularly, when turbidity surpassed benchmark turbidity scope, the detergent amount that then is judged as input was greater than benchmark detergent amount (that is, the detergent amount of input is more), and washed with the wash time of the shortening of regulation.
On the contrary, when benchmark turbidity and a turbidity, in the certain limit of benchmark turbidity, the detergent amount that then is judged as input is equivalent to benchmark detergent amount (that is, the detergent amount of input is suitable) as if a turbidity, and washs with predetermined wash time.
And if turbidity is lower than the prescribed limit of benchmark turbidity, the detergent amount that then is judged as input is lower than benchmark detergent amount (that is, the detergent amount of input is less), and washs with predetermined wash time.
In the above-mentioned explanation, the benchmark detergent amount is the detergent amount when dropping into the washing agent of appropriate amount based on washing weight, and at this moment washings turbidity is in the certain limit of benchmark turbidity.
Below, describe feature in detail according to the control part 70 of second embodiment of the invention.
When washing machine carries out washing procedure with the wash time that shortens, the time point that begins from washing procedure through second stipulated time after, control part 70 control turbidity test sections 20 make it detect the secondary turbidity of washings, and from second stipulated time through the 3rd stipulated time after, control turbidity test section 20 makes its three turbidity that detect washings, compares secondary turbidity and three turbidity then.
More specifically, the time that second stipulated time heating part 30 when washing with warm water stops to heat, if the dustiness of washings is low, then the washing of washings is finished and turbidity does not almost change substantially at run duration in heating part 30, if but the dustiness height of washings, then heating part 30 stops to change because of spot continues to ooze out turbidity after the heating.Therefore, relatively heating part 30 time point that stops to move promptly second stipulated time the secondary turbidity and from three turbidity of second stipulated time through the 3rd stipulated time, judge the washing degree of washings thus.
And when washing with cold water, second stipulated time was the time from the 30%-40% of time point process total washing procedure time that washing procedure begins.
At this, the comparative result of secondary turbidity and three turbidity, if the turbidity recruitment is lower than reference range, then spot is oozed out and be need not to carry out too much washing from washings fully.Thus, even shorten wash time, the washing force when washing force also is same as and washs with predetermined wash time is finished washing so keep the wash time of shortening.
But the comparative result of secondary turbidity and three turbidity if the turbidity recruitment is not less than reference range, then is judged as spot and does not ooze out from washings fully.In view of the above,, then can not finish sufficient washing, so the wash time that shortens is reverted to predetermined wash time to finish sufficient washing if wash with the wash time that shortens.
Simultaneously, storage part 70 stores the shortening time based on detergent amount.
Below, the formation according to the control part 70 of third embodiment of the invention is described.
Simultaneously, display part 80 shows the shortening of wash time or reverts to information such as being scheduled to wash time, and shows whether washing agent needs additional input.
Below, the formation according to the control part 70 of fourth embodiment of the invention is described.
Below, the formation according to the control part 70 of fifth embodiment of the invention is described.
Simultaneously, storage part 90 stores the maximum rinsing number of times based on detergent amount, and stores the rinsing turbidity benchmark that need not to carry out more rinsing program, promptly stipulates turbidity.
Fig. 4 is the washing machine control action flow chart according to first embodiment of the invention, and first embodiment provides and utilizes the washings turbidity to determine detergent amount and regulate the control method for washing machine of wash time.With reference to Fig. 1,2 and Fig. 4 first embodiment is described.
During the washing washings, the user puts into washings in the cylinder 14, and washing agent is put in the detergent box.
When the user selects washing mode and function and moves washing machine, washing mode and the function setting wash time that washing machine is selected based on the user also is stored, when rotating, detect washing weight (101) the back water supply start in the cylinder 14 according to startup cylinder 14 stirrings of motor 15.
In addition, when utilizing load sensor to detect washing weight, behind the detection washing weight, in washtub 13, supply with washings corresponding to detected weight; And when being detected washing weight, supply with the once washing water that is used to soak washings by the washings that soaked, detect washing weight based on the washings that soaks afterwards after, additional washings to washtub 13 in corresponding to detected washing weight.
During water supply, because of in washtub 13, supplying water, so the washing agent of any amount that is stored by the user is along with washings together supply to washtub 13 by the detergent box 17 that is connected in water supply pipe 16.
After finishing water supply, the process detergent dissolution time i.e. first stipulated time (102), then detects a turbidity (103) of washings, and utilizes a turbidity that detects to determine to drop into detergent amount (104).
At this moment, it is to utilize at least more than one turbidity transducer to carry out the detection of washings that turbidity detects, and when detecting the washings turbidity when utilizing a plurality of turbidity transducers, then utilizes the detected turbidity of some turbidity transducers.
Simultaneously, in order to guarantee the degree of accuracy of washings turbidity, also can be through after i.e. first stipulated time of detergent dissolution time, turbidity when the detection motor stops each time in the stipulated time of first stipulated time, and calculate the average turbidity of a plurality of turbidity of detection, thereby determine to drop into detergent amount according to the average turbidity that calculates.
Secondly, the benchmark turbidity that extracts based on washing weight from storage part 90, and benchmark turbidity and turbidity that extracts compared, judge that thus whether the detergent amount that drops into is above benchmark detergent amount (105).
At this, the benchmark detergent amount is for dropping into the detergent amount of keeping average washing force based on the washing agent of the appropriate amount of washing weight, and a turbidity of washings at this moment is in the reference range of benchmark turbidity.
Specifically,, then be judged as the detergent amount (that is, the detergent amount of input is more) that has dropped into greater than the benchmark detergent amount, thereby wash (106) with the wash time that shortens if turbidity surpasses the reference range of benchmark turbidity.
On the contrary, behind benchmark turbidity and the turbidity, if a turbidity in the reference range of benchmark turbidity, then is judged as and has dropped into the washing agent (that is, the detergent amount of input is suitable) that is equivalent to the benchmark detergent amount; If a turbidity is lower than the reference range of benchmark turbidity, then is judged as the detergent amount (that is, the detergent amount of input is less) that has dropped into less than the benchmark detergent amount, thereby washs (107) with predetermined wash time.Below, describe with reference to Fig. 5,6.
According to the curve map of the washing force of detergent amount, washing force increases along with detergent amount and becomes big Fig. 5 as we know from the figure during for the identical washings of expression washing weight.
Fig. 6 is the change curve according to the washings turbidity of detergent amount, and it illustrates the result of turbidity transducer 1,2, the 3 bases turbidity that the mutually different locational washings of position probing are set separately that is arranged at mutually different position.At this, (b) of Fig. 6 is for having dropped into than the situation of the washing agent of Fig. 6 (a) many about 2 times.
Learn that thus compare when carrying out washing procedure as (a) of Fig. 6 with less detergent amount, the washings turbidity is higher when (b) as Fig. 6 carries out washing procedure with more detergent amount.
And can learn, begin to keep the time point of turbidity more for a long time early than the time point that begins to keep turbidity as (a) detergent amount of Fig. 6 more after a little while as (b) detergent amount of Fig. 6.That is, detergent amount is many more, and the time point that then begins to keep certain turbidity more early.That is, detergent amount is many more during washing procedure, and washing force is high more.
At this, the time point that begins to keep certain turbidity is that spot is oozed out and turbidity is initially located in the time point of saturation state from washings fully, the time point that oozes out from washings fully because of spot early, so even carry out the washing of longer time, washing force is still identical, so can shorten washing procedure.
So, when the detergent amount that drops into more for a long time, washing force will be higher than average washing force.Determine the detergent amount that drops in view of the above and regulate wash time, thereby can keep the washing force of certain level, and can shorten wash time, can save the power consumption in the washing thus.
Fig. 7 is the control action flow chart according to the washing machine of second embodiment of the invention, and second embodiment provides and utilizes the washings turbidity to determine detergent amount and regulate the control method for washing machine of wash time.Below, with reference to Fig. 4 and Fig. 7 second embodiment is described.
Judge when the turbidity that utilizes washings and to drop into detergent amount and when shortening wash time and wash (106), judge the washing degree of washings and judge whether to keep the wash time of shortening according to judged result.
Specifically, from the beginning washing procedure time point through second stipulated time (106-1), then detect the secondary turbidity (106-2) of washings, from second stipulated time through the 3rd stipulated time (106-3), then detect three turbidity (106-4) of washings, whether judge the turbidity increase thus, promptly judge the recruitment of secondary turbidity and three turbidity.
At this moment, second stipulated time was the time that heating part 30 stops to heat when washing with warm water, and during with icy water washing second stipulated time be the time point that begins from washing procedure time through the 30%-40% of total washing procedure time.
Simultaneously, Fig. 8 is the washings turbidity change curve figure at each program that whether heats according to washings, (a) of Fig. 8 heats (promptly for washings, warm water) the washings turbidity change curve figure the time at each program, and Fig. 8 (b) washings turbidity change curve figure when not heating (that is cold water) for washings at each program.
Can learn, compare when carrying out washing procedure with the washings (that is, cold water) that not have heating as Fig. 8 (b), the washings turbidity as the washings (that is warm water) of (a) usefulness heating of Fig. 8 higher when carrying out washing procedure.Therefore can learn, carry out washing procedure, then improve the washing force of washings as if heated scrub water.
Secondly, judge whether the turbidity recruitment is lower than reference range (106-5) and judges whether to keep the wash time of shortening.
That is, when the turbidity recruitment is lower than reference range, is judged as spot and oozes out and turbidity does not change from washings fully, therefore keep the wash time of shortening and wash (106-6).
At this, turbidity does not change and is meant and finishes sufficient washing, is same as washing force when washing with predetermined wash time even therefore shorten its washing force of wash time yet.
On the contrary, when the turbidity recruitment is not less than reference range, then is judged as spot and does not ooze out and turbidity changes from washings fully, therefore revert to predetermined wash time and wash (106-7).
In view of the above, again the wash time that shortens is reverted to predetermined wash time and wash, therefore can finish sufficient washing.
Judge except detecting twice turbidity at least as mentioned above the washing degree methods, also can use till reaching for the 3rd stipulated time after second stipulated time and periodically detect turbidity, and judge the recruitment of the turbidity that periodically detects, and judge the saturation state of the washings turbidity that the pollution because of washings causes thus.
Fig. 9 is the control action flow chart according to the washing machine of third embodiment of the invention, and the 3rd embodiment provides and utilizes the washings turbidity to determine detergent amount and inform user's additional input washing agent whether control method for washing machine.Below, with reference to Fig. 1,2 and Fig. 9 the 3rd embodiment is described.
During the washing washings, the user puts into washings in the cylinder 14, and washing agent is put in the detergent box.
When the user selects washing mode and function and moves washing machine, washing mode and function setting wash time based on user's selection, and when stirring rotation, detect washing weight (201) the back water supply start in the cylinder 14 according to the startup cylinder 14 of motor 15.
During water supply, because of washings flow in the washtub 13 by the detergent box 17 that is connected in water supply pipe 16, so the washing agent of any amount of being deposited by the user is along with washings together supply to washtub 13.
