It will be understood that terms, such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
The invention takes a washing machine as an example to introduce a detergent adding method of a general washing device, and the working principle and the function of the detergent adding method can be embodied in other similar washing devices correspondingly; firstly, as shown in the main flow of the general washing process of fig. 1, before washing, a laundry preparation (putting in the laundry, turning on the power supply, etc.) needs to be made, and a detergent is prepared at the time of the laundry preparation, such as a drum washing machine with a detergent box (putting in the detergent box first), such as a pulsator washing machine (directly pouring in, or a detergent tank at the upper part), such as a washing machine with an automatic pouring function, and a large amount of detergent put in advance is poured by adopting a pouring pump; then the main washing process is started, water is firstly moistened, water is fed, and the detergent enters the washing drum for mixing; a main washing stage, in which the drum rotates to wash out dirt in clothes, and after washing for a certain time, the water is drained, and the main washing is completed; then rinsing is carried out; after rinsing, the washing was completed. A main wash is generally adopted, and a detergent is added, and the detergent is generally estimated and excessive to avoid unclean washing, but the specific condition of the clothes washed each time is different, so that the detergent washed for a certain time is insufficient, and finally the unclean washing is caused.
The invention relates to a detergent adding method, which comprises the following steps as shown in figure 2: s1, acquiring data, namely acquiring TOC value Z and/or TOC value change rate K of washing water in a washing container in a washing stage of main washing; s2, judging conditions, namely judging whether the TOC value Z and/or the TOC value change rate K meet preset conditions or not; s3, executing control, and executing additional detergent if the TOC value Z and/or the TOC value change rate K meet preset conditions, wherein the preset conditions are conditions related to the TOC value Z and/or the TOC value change rate K; TOC is a detection mode for detecting the total amount of organic matters in water, can accurately reflect the content of the organic matters in the water, can detect suspended organic matters, can detect common pigments, food stains, organic additives and most of detergents which are soluble in the water, and can reflect the dirty amount of the washing water through TOC detection, thereby being used for judging cleanliness to control washing, wherein the TOC unit is g/L and represents the embodiment of the organic carbon content in the water; according to the scheme, whether the detergent in the water is consumed or not is effectively indicated by judging the TOC value Z and/or the TOC value change rate K, so that the additional detergent is added, and the optimal washing effect is achieved; the embodiment can solve the problem that the detergent is insufficient to cause unwashed, thereby optimizing the problem that the prior art only puts the detergent once and can not additionally add the detergent according to the actual washing degree, and finally achieving better washing effect and user experience; on the other hand, the problem that the clothes are damaged or rinsed too much caused by excessive single addition of the detergent in the prior art can be avoided.
In some embodiments, specific preset conditions may include: whether the TOC value Z meets the set TOC value and/or whether the TOC value change rate K meets the set change rate value; on the one hand, the TOC value can be a preset TOC value threshold value or a range value of TOC values, and the TOC value change rate K is also applicable to be obtained according to specific experimental measurement or obtained according to specific clothes, detergent conditions and the like; of course, either the TOC value Z alone or the TOC value change rate K alone or a combination of both may be employed; or satisfies a certain formula condition, size judgment, etc., without limiting the threshold value or the range, it is the size judgment of the value or the setting falling into a certain range that is optimal and accords with simple logic.
May also be more specific in some embodiments, include determining whether TOC value Z is largeAt or below TOC threshold Y i And/or judging whether the TOC value change rate K is greater than or equal to the change rate threshold K i The method comprises the steps of carrying out a first treatment on the surface of the If TOC value Z is greater than or equal to TOC threshold Y i And/or the change rate K is greater than or equal to the change rate threshold K i Executing the additional addition of the detergent once and continuing to execute the washing stage after the addition of the detergent; wherein i=0, 1,2, … …; the scheme can be that the TOC value Z is increased to the threshold value Y i And/or the rate of change reaches a threshold value K i Indicating that the water is depleted of detergent, but the soil is not yet cleaned, and that detergent is still needed, indicating that detergent is added, wherein the threshold value Y i The threshold value should be the corresponding threshold value after each addition of detergent, and i=0 is the initially added detergent.
In some embodiments, the method further comprises, if TOC value Z < threshold Y i And/or the rate of change K < the rate of change threshold K i Executing the end of the washing stage and entering drainage; more specifically, if the TOC value and/or the change rate K is smaller than the set value, the dirt is cleaned, the cleaning effect is achieved, the water draining can be ended, and the next stage is started; or the washing may not be sufficiently performed under the condition, and the washing still needs to be continued, and the judgment is performed under a certain condition.
In some embodiments, the unwashed is indicated by judging that the TOC value Z is greater than or equal to the threshold value Y, so that the detergent is additionally added, and the unwashed problem caused by insufficient detergent is avoided; the TOC value Z is smaller than the threshold value Y, which indicates that the washing stage can be finished and the water is drained, and the main washing can be finished; on the other hand, after the detergent is added, the washing can be continued, and then the main washing is ended.
In some embodiments, further, the detergent may be added multiple times, and the TOC value may be measured after each addition (taking the TOC value as an example, of course, from the above embodiments, the change rate K or a combination of the two may also be used, where the TOC value is taken as an example for avoiding redundancy, and the case of the change rate K is not excluded), so that the main wash is finally achieved, and the TOC value Z of the wash water in the wash container is obtained in the main wash stage (that is, the TOC value may be measured in the wash stage after each addition of the detergent); judging whether the TOC value Z is greater than or equal to the TOC threshold value Y i The method comprises the steps of carrying out a first treatment on the surface of the If it isTOC value Z is greater than or equal to threshold value Y i I=i+1 is executed (i.e., the start of the action of adding the detergent is described), the additional addition of the detergent is executed, and the washing stage after the addition of the detergent is continued (after the addition, the washing stage is not affected, and the washing stage is continued); of course if TOC Z < threshold Y i Then the end of the washing phase is performed, entering the drain, where i=0, 1,2, … …; the problem that the cleaning is not yet caused by adding the TOC agent once can be prevented by adding the TOC agent for a plurality of times, and TOC detection can be carried out each time of adding the TOC agent for a plurality of times so as to achieve the aim of optimizing, and the TOC value Z after each time needs to be equal to the threshold value Y after the addition i In comparison, since the addition of detergent may cause an increase in TOC, a new threshold is required.
In some embodiments, further, the number of times limit may be increased to achieve the optimization of washing, after the operation of increasing the number of times (i=i+1), if i > the preset maximum number of times j, i.e. the number of times i of adding the detergent exceeds the preset maximum number of times j, the end of the washing stage is executed, and the drainage is entered; if i is less than or equal to the preset maximum times j, namely the adding times i of the detergent does not exceed the preset maximum times j, executing additional adding of the detergent once, and continuing executing the washing stage; for example, the maximum number of additions may be set to 5, this time to 4, and the TOC value Z may be determined 4 Not less than threshold Y 4 Judging that the detergent is required to be added once, wherein i=5 at the moment, the preset maximum times are not exceeded, the detergent is added, and washing is continued after the detergent is added; thereafter determining whether TOC value or Z 5 Not less than threshold Y 5 It is determined that one addition is required, and when i=6, the preset maximum number of times has been exceeded, no detergent is required to be added, and the washing stage is completed.
In some embodiments, further schemes are needed, and further optimization of detergent dosage, washing time, detergent increment, washing time increment, etc. is needed to achieve controllable detergent increment and washing optimization; the clothes weight m can be obtained by weighing, and the corresponding detergent input quantity V can be obtained through the weight m 0 Obtaining corresponding initial preset washing time T 0 V is put in a water inlet wetting stage 0 A detergent;when the additional addition of the detergent is performed once, the added detergent is added in an amount of DeltaV i At this time, the total detergent dosage V i ＝V i-1 +ΔV i (i.e., the previous total amount plus this added amount), the wash stage time DeltaT is increased i Preset total washing time T i ＝T i-1 +ΔT i (i.e., the previous total time plus this added time), where i is for clarity, i=1, 2,3, … …; since the detergent is added, in order to wash sufficiently, it may be necessary to additionally increase the washing time in the case of the previous preset washing time to satisfy the washing time of the total amount of the present detergent, so that the relevant steps are optimized here.
Further, in a specific implementation, the above increment or initial values have their correlation, and the correlation is also applied in the relevant cases to achieve a more accurate delivery. A general washing machine may suggest a detergent dosage V 0 The relation with the weight m of the laundry (how much detergent can wash) is not optimal, since the relation of the amount is related to the type of detergent (laundry capacity, concentration), the degree of dirt actually contained in the laundry, the detergent dosage V 0 Just as the weight m of the clothes; the present protocol can take the existing experience values and reduce them appropriately (since the existing experience values often amplify the data for cleaning purposes, but the detergent will be placed in excess). For example, 3g of detergent may be used to wash 1kg of laundry, and the water addition is also fixed (e.g. 1L) and is also relevant, for example, the washing stage time is 10min (possibly related to the amount of detergent, the weight of laundry), assuming an organic carbon content of 2g in the detergent, the initial TOC value X for the detergent at this time 0 =2g/L, threshold Y assuming that such a detergent can wash out 10g of dirt (organic carbon) 0 12g/L (TOC includes 2g detergent and 10g dirt), these data have the correspondence given by way of example (3 g detergent-1 kg laundry-1L water-10 min wash, X 0 ＝2g/L，Y 0 =12 g/L); in the subsequent washing process, if TOC value Z is obtained 0 ＝7g/L(＜Y 0 ) Description X 0 =2g/L, wash out 5g of dirt,indicating that the remaining 1g/L of detergent is not functional, and that the detergent is excessive, indicating washing; if the TOC value Z is obtained 0 ＝12.5g/L(＞Y 0 ) Indicating that more dirt is in the water and the detergent is used up, the dirt cannot be washed out again, the detergent needs to be added, i=1, and Δv is added 1 Detergent, here DeltaV 1 May be a fixed value, optimally a sum Z 0 -Y 0 The number of values (which may indicate how much detergent is to be applied for the possible unwashed dirt in these small amounts of water), for example as much as 0.5g/L for the possible dirt as 5g, the detergent DeltaV to be added 1 ＝1.5g(ΔTOC 1 ＝ΔX 1 =1 g/L), total final detergent dosage V 1 ＝4.5g(X 1 =3 g/L), threshold Y 1 The small amount of water relative to the total amount of water carried in by the addition of detergent is ignored here (the optimal algorithm should be to take as denominator the increase in wash water volume resulting from the increased water), for which increased detergent the time required is increased by 5min, t 1 ＝T 0 +ΔT 1 The washing is continued for a period of time that has been already washed, until the total time is 15min, during which the TOC value Z also needs to be measured 1 Continuing to judge; also, a limit on the maximum number j can be added, for example, when Z is reached 5 The limit of the maximum number of times is 5 times, i=i+1=6, and if the limit is exceeded, the washing stage can be ended after the remaining time of washing is set (i.e. washing to t=preset washing time T) 5 End). It should be noted that the correspondence of various quantities is generally a complex process, in which the primary function, the secondary function, the proportional relationship, etc. may be obtained by experimental measurement, in this case, a simpler proportional relationship is adopted, Y i ＝(1+a)X i And example a=5; and set Z 0 -Y 0 The value of =0.5 g/L corresponds to a possible amount of dirt of 5g, which is ultimately related to a number of factors such as the degree of dirt, concentration, etc., and also requires experimental measurements.
In some embodiments, the method further comprises obtaining a washing stage time T, if T is greater than or equal to a preset washing time T i Then washing is performedAfter the washing stage is finished, entering drainage; otherwise, continuing to execute the washing stage; this way, a limitation of the maximum washing time is set, all that is embodied in the above embodiment; may also be set if TOC value Z < threshold value Y i It is possible that the washing is not yet complete and the limitation of the maximum washing time needs to be satisfied, so that the washing process can be perfected and bad user experience caused by overlong washing is prevented.
In some embodiments, the method further comprises, if TOC value Z < threshold Y i Obtaining the change rate K of TOC value of the washing water in the washing container, if the change rate K is less than the preset change rate K i Executing the end of the washing stage and entering drainage; this embodiment further more specifically describes the limitation of the rate of change on the basis of the foregoing, e.g. TOC value Z < threshold Y i Possibly the washing is not complete, at which time the rate of change K is judged to be less than the preset rate of change K i (preset rate of change K set) i A low value), indicating that the change rate is smaller than a threshold value, the TOC value Z is smaller and the increasing trend is smaller, the washing stage can be judged to be stable, the TOC is not increased any more, the washing is considered to be complete, and at the moment, Z is smaller than the threshold value Y i The cleaning is described, the cleaning stage can be ended, and a better logic judgment effect can be achieved by matching with the limitation of the cleaning time or the display of the times.
In some embodiments, the method comprises the steps of: the TOC value Z of the washing water in the washing container is obtained in the washing stage of the main washing; judging whether the TOC value Z is larger than or equal to a TOC threshold Y; if the TOC value Z is more than or equal to the threshold value Y, executing additional detergent addition; if the TOC value Z is less than the threshold value Y, executing the end of the washing stage, and entering drainage; TOC is a detection mode for detecting the total amount of organic matters in water, can accurately reflect the content of the organic matters in the water, can detect suspended organic matters, can detect common pigments, food stains, organic additives and most of detergents which are soluble in the water, and can reflect the dirty amount of the washing water through TOC detection, thereby being used for judging cleanliness to control washing, wherein the TOC unit is g/L and represents the embodiment of the organic carbon content in the water; according to the scheme, the TOC value Z is judged to be more than or equal to the threshold value Y, and the unwashed state is indicated, so that the detergent is additionally added, and the unwashed problem caused by insufficient detergent is avoided; the TOC value Z is smaller than the threshold value Y, which indicates that the washing stage can be finished and the water is drained, and the main washing can be finished; on the other hand, after the detergent is added, the washing can be continued, and then the main washing is finished; the embodiment can solve the problem that the detergent is insufficient to cause unwashed, thereby optimizing the problem that the prior art only puts the detergent once and the detergent can not be additionally added according to the actual washing degree, and finally achieving better washing effect and user experience.
In some embodiments, the method further comprises, if TOC value Z < threshold Y i Obtaining the change rate K of TOC value of the washing water in the washing container, if the change rate K is less than or equal to the preset change rate K i Executing the end of the washing stage and entering drainage; this embodiment increases the rate of change limit on the basis of the foregoing, e.g. TOC value Z < threshold Y i Possibly the washing is not complete, and the change rate K is not more than the preset change rate K i (preset rate of change K set) i A low value), indicating a rate of change less than a threshold value, TOC value Z i The change is small, the increasing trend is small, the stable washing stage can be judged, the TOC is not increased any more, the complete washing can be judged, and at the moment, Z is less than the threshold value Y i The cleaning is described, the cleaning stage can be ended, and a better logic judgment effect can be achieved by matching with the limitation of the cleaning time or the display of the times.

Although embodiments of the present invention have been disclosed above, it is not limited to the use of the description and embodiments, it is well suited to various fields of use for the invention, and further modifications may be readily apparent to those skilled in the art, and accordingly, the invention is not limited to the particular details without departing from the general concepts defined in the claims and the equivalents thereof.
The foregoing describes specific embodiments of the present disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes in the figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented with "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but HDL is not only one, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed, integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
