Detailed Description
The technical contents of the invention are described in detail below with reference to the accompanying drawings and specific embodiments.
In the conventional washing apparatus, a corresponding fixed rotation/stop ratio is usually set according to a washing program, or a special rotation/stop strategy is designed for a certain washing operation. These washing control methods only take into account and generally only achieve the washing effect in the general case, and do not take into account the influence on the service life of the motor. Embodiments of the present invention provide a control method for a washing apparatus, which enables a rotation/stop ratio to be appropriately changed during a washing process by a specially designed segment-type rotation/stop ratio control manner (a washing time is divided into a plurality of relatively equal time segments, a rotation/stop ratio corresponding to each time segment is calculated in each time segment, and such a rotation/stop ratio parameter is referred to as a segment-type rotation/stop ratio).
Fig. 1 is a schematic flow chart illustrating a control method of a washing apparatus according to an embodiment of the present invention. Referring to fig. 1, the method includes:
100: in the washing process, the working parameters corresponding to the current time slice are acquired in time slices, and the washing process comprises a plurality of time slices. Wherein the operating parameters corresponding to a later time segment are determined on the basis of the state parameters acquired in at least one preceding time segment.
102: and in each time segment, performing washing control according to the working parameters corresponding to the time segment.
Optionally, in an implementation manner of this embodiment, the operating parameter includes a stop-and-go ratio; the state parameters comprise water turbidity and/or motor current (drive current). Of course, based on the idea provided by the embodiment of the present invention, in other embodiments, the operating parameter may further include or be replaced by a rotational speed, and the motor current in the state parameter may further include or be replaced by a motor voltage. That is, although the embodiment of the present invention is mainly described by taking the operating parameters as the rotation speed ratio, and the state parameters including the turbidity of water and/or the motor current as examples, those skilled in the art can flexibly set the alternative parameters of the specific operating parameters and state parameters mentioned in the embodiment based on the characteristics, effects, principles, and the correlation between the physical parameters, and the like, and this is also within the protection scope of the present invention.
Optionally, in an implementation manner of this embodiment, the operating parameter value of a first time slice in the plurality of time slices is a set value, and the set value may be determined according to experiments or experience.
By adopting the method provided by the embodiment, on one hand, the segment-type stop-and-go ratio is adopted, so that the intermittent or periodic change of the stop-and-go ratio in the washing process becomes possible; on the other hand, the working parameters of the later time segment are determined by using the state parameters of the prior time segment, so that the rotation-stop ratio of the actual state corresponding to the state parameters can be obtained. For example, when the state parameters include both turbidity of water reflecting the washing state and motor current for quantifying a motor loss degree, a stop-and-go ratio that takes both washing cleanliness and motor life into consideration can be obtained.
Optionally, in one implementation of this embodiment, the number of time slices (hereinafter referred to as total number) involved in a wash process is determined in the following manner: a) acquiring a weight value of clothes in the washing equipment and an initial turbidity value (namely, initial turbidity of water) after water is filled; b) Determining the total number based on the weight value and turbidity value. In this implementation, the duration of a single time segment is relatively fixed, and thus, the total number can reflect the total duration of the wash. And the total amount of the washing time is determined based on two actual data, namely the weight value of the clothes and the initial turbidity value after water injection, so that the washing time relatively meeting the actual requirement can be obtained, and compared with the fixed washing time or the washing time corresponding to the washing mode in the prior art, the washing time more meets the actual washing requirement, and the washing machine/motor loss can be reduced while the washing effect is ensured.
Further, step b may be implemented by: and adjusting the standard quantity of the plurality of time slices according to a first adjusting coefficient corresponding to the weight value and a second adjusting coefficient corresponding to the turbidity value to obtain the actual quantity of the plurality of time slices. Wherein the standard number is the number of time segments that a wash process contains under relatively normal conditions. The relative normality can be defined by itself as required, for example: and counting the weight interval of the clothes load under the common washing condition and the water turbidity value interval after water is injected, and taking the condition falling in the interval range as the relatively normal condition. The number of time segments involved in a relatively normal design of a washing process is taken as the standard number. The standard amount may be obtained through experiments, for example, the amount of time segments included in one washing process is used as a variable, the washing effect is measured by using other states/parameters as constants, and the standard amount is determined through analysis according to the washing effect, the motor consumption and the like corresponding to different amounts of time segments.
Optionally, in step b, it is further determined whether the number obtained by adjusting the standard number is within a valid range. If the number is within the effective range, taking the adjusted number as the actual number; and if the actual number is not in the valid range, taking the standard number as the actual number. In this way, the uncertainty of the calculated quantity can be limited (for example, on the basis of the results of an analysis based on experimental data), ensuring proper functioning in a defined manner, for example in the case of errors in the sensors, errors in the calculation function, unknown extreme washing environments, etc.
Optionally, in an implementation manner of the embodiment of the present invention, "determining the working parameter corresponding to the later time segment based on the state parameter acquired in at least one previous time segment" may be implemented specifically in the following three manners:
the first method is as follows: when the state parameter comprises water turbidity, analyzing a first reference state based on an array of water turbidity values continuously acquired in the at least one previous time slice; and comparing the first reference state with a preset first reference state, and determining working parameters corresponding to a later time slice (hereinafter, a rotation-stop ratio is taken as an example for description). Wherein the first reference state reflects a washing effect. And when the current washing effect is displayed in a contrast manner and is weaker and does not meet the exceptional condition, adjusting the working parameters corresponding to the later time segment in the direction of increasing the working parameters, and when the current washing effect is displayed in a contrast manner and is stronger, adjusting the working parameters corresponding to the later time segment in the direction of reducing the working parameters (defined as an adjustment strategy a).
Wherein the exception condition comprises: the current time slice is at a set position among the plurality of time slices. That is, in some time slices, especially in the last part of time slices, the washing effect is weak but the washing effect is normal, and the increase of the working parameters of the subsequent time slices has no obvious positive effect. Or, the exception condition includes: the difference between the average value of turbidity in the current time segment and a set reference value of turbidity (e.g. an initial turbidity value or an empirical value as the reference value of turbidity) exceeds a set threshold. Exceeding the set threshold indicates that the laundry is relatively clean, so that the operating parameters of the time duration segment need not be deliberately increased.
It is clear that in other embodiments of the invention, other exceptions may be found and exception conditions set in order to avoid negative effects due thereto.
In the present implementation, the first reference state includes at least one of a water turbidity saturation tendency and a water turbidity change tendency, for example. In the general direction, the rotation-stop ratio is reduced when the water turbidity saturation trend shows that the water turbidity value approaches saturation, and the rotation-stop ratio is increased on the contrary; and increasing the rotation-stop ratio when the water turbidity change trend is reduced, and conversely, reducing the rotation-stop ratio. When two reference states of the water turbidity change trend and the water turbidity saturation trend are simultaneously synthesized for processing, debugging can be carried out according to actual conditions and experimental data so as to determine the comprehensive condition of increasing/decreasing the rotation-stop ratio. The present invention is not particularly limited to this debugging process.
In the first mode, taking the first reference state as the water turbidity saturation tendency as an example, the first reference state may be a plurality of water turbidity saturation curves obtained by using a relationship between "clothes weight and initial turbidity of water" and "corresponding water turbidity saturation curves" obtained through experiments. At this time, the "determining the working parameter corresponding to the later time segment according to the comparison between the first reference state and the preset first reference state" may be understood as: during the washing process, a matching curve is selected according to the weight of the clothes and the initial turbidity of the water, and then during the washing process, the rotation-stop ratio is adjusted in a mode of fitting the turbidity value of the water to the matching curve as far as possible.
In a first mode, taking the first reference state as an example of a water turbidity saturation trend, the first reference state may be a uniform water turbidity saturation curve set according to a large amount of experimental data, and in this case, the "determining the working parameters corresponding to the later time segment according to the comparison between the first reference state and a preset first reference state" may be understood as: during the washing process, the spin-to-stop ratio is adjusted in such a way that the water turbidity values are fitted as far as possible to the uniform water turbidity saturation curve.
In the above, the first reference state is taken as the water turbidity saturation tendency as an example, and the comparison logic of the first reference state and the first reference state is exemplified. Based on the same or similar logic, when the first reference state is a water turbidity variation trend, a person skilled in the art may design a corresponding first reference state and a corresponding comparison logic, which is not specifically limited in this embodiment of the present invention. Moreover, the foregoing examples are merely for the convenience of the reader and do not indicate that only the foregoing examples may be employed. For example, a table look-up (corresponding relationship between the known parameters and the stop-and-go ratio determined according to experimental data) according to the currently known parameters (for example, the number of remaining time segments, the weight of the clothes, the current water turbidity value and/or the current effective value) can be adopted to determine the stop-and-go ratio corresponding to the later time segment.
The second method comprises the following steps: when the state parameters comprise motor current, analyzing to obtain a second reference state based on the motor current numerical value continuously acquired in the at least one previous time segment, comparing based on the second reference state and a preset second reference state, and determining working parameters corresponding to a later time segment. Wherein the second reference state reflects the motor operating state, such as a change in the effective value of the motor current (change over time, degree of fluctuation at different stop-and-go ratios, etc.). And if the comparison shows that the current motor running load is higher/lower, adjusting the working parameter corresponding to the later time slice (defined as an adjustment strategy b) in the direction of reducing/increasing the working parameter.
The second reference state is a current effective value curve (similar to the "matching curve" or the "uniform turbidity saturation curve" in the first mode) determined according to experimental data and suitable for guaranteeing the service life of the motor. The logic for comparing the second reference state with the second reference state is the same as or similar to the logic for comparing the first reference state with the first reference state in the first mode, and is not repeated here.
The third method comprises the following steps: and when the state parameters comprise water turbidity and motor current, integrating the first reference state and the second reference state to determine the corresponding working parameters of the later time segment. The third method can be understood as a fusion application of the foregoing adjustment strategy a and adjustment strategy b. As for increasing or decreasing the stop-and-go ratio when the first reference state and the second reference state simultaneously satisfy what kind of condition, and how to give priority to the washing effect or the motor life to make a more flexible and changeable strategy when considering both the washing effect and the motor life, those skilled in the art can completely debug the parameters according to the actual data and the design purpose on the basis of the disclosure of the present invention, and the present invention is not specifically limited to this.
From the above description of the three modes, those skilled in the art should understand that the first/second reference state is an actual state obtained by analyzing the collected data, and the data analysis is not limited to an average value, a root mean square (effective value), a variation trend, a fluctuation degree, and the like, and may perform data analysis in different modes for calculation according to the characteristics of the detected data. It will also be appreciated by those skilled in the art that the first/second reference states may be ideal or preferred states analyzed from historical data, experimental data, etc., and may be in the form of functions, curves, tables, etc. Those skilled in the art will also appreciate that the third mode can be understood as a fusion of the first mode and the second mode, which provides a multi-dimensional state (e.g., washing state, motor operating state) fusion to make a stop-and-go ratio optimization idea taking into account multi-dimensional effects (washing effect, motor losses).
As is apparent from the above description, with the above three ways of the present embodiment or the similar ways thereto, the spin-stop ratio can be appropriately adjusted based on the consideration of the washing effect and/or the motor life.
Optionally, in an implementation manner of this embodiment, the "determining the working parameter corresponding to the later time segment based on the state parameter collected in the at least one previous time segment" further includes: and if the determined working parameter corresponding to the later time segment is not in the effective range, adjusting the working parameter to the effective range to ensure that at least the minimum required washing effect can be achieved and the controllable range of the motor cannot be exceeded.
Optionally, in an implementation manner of this embodiment, the at least one previous time slice includes a time slice adjacent to a following time slice to ensure timeliness of the rotation-stop ratio adjustment value, or includes two or more consecutive time slices before the following time slice to take timeliness and globality of the rotation-stop ratio adjustment value into account.
Fig. 2 is a flowchart illustrating a control method of a washing apparatus according to an embodiment of the present invention. Referring to fig. 2, the method includes:
200: the laundry weight W is acquired and the load weight value G _ weight (i.e., the first adjustment coefficient) is determined. Specifically, the method comprises the following steps: after the washing program is started, firstly weighing the clothes to obtain the weight value W of the clothes, synchronously starting a rotation-stop ratio calculation program in the system, collecting the weight value W of the clothes, calculating the corresponding load weight value G _ weight of the clothes and storing the weight value G _ weight for subsequent rotation-stop ratio calculation.
202: and acquiring a turbidity value D of the water after water injection, and determining a turbidity weighted value G _ dirty (namely a second adjusting coefficient). Specifically, the method comprises the following steps: and after weighing is completed, water is injected into the barrel, the turbidity numerical value D of the water is obtained from the corresponding water quality turbidity detection equipment and is used for judging the cleanliness of the clothes washed at this time, and synchronously, the system can receive the turbidity numerical value D of the water, calculate the corresponding turbidity weighted value G _ dirty and store the turbidity numerical value D for the calculation of the subsequent rotation-stop ratio.
204: and adjusting the standard number of the time segments by using the load weighted value and the turbidity weighted value to obtain the calculated number of the time segments.
Specifically, the method comprises the following steps: the calculation module adjusts an internally preset washing time segment T _ pre (i.e., a standard number) according to the load weight value and the turbidity weight value to obtain a calculated washing time segment T _ comp:
Tcomp＝foor(Gweight*Gdirty*Tpre)
wherein, T _ pre is an integer value representing the total number of preset washing time segments (or the number of times of the switching of the rotation/stop ratio), and the preset washing time segment number is the washing time segment number under the relatively normal condition (normal clothes load and normal water turbidity). G _ weight and G _ dirty are weighted numbers of 0-2 and are used for adjusting T _ pre. Of course, in other embodiments, the range of weighting values and the formula can be flexibly adjusted. For example, the effective range of the weighting value is changed to "-2 to 2", and the formula is changed to T _ comp (| G _ weight + G _ dirty |) T _ pre.
The calculated value is rounded down and stored in T _ comp. The effect of this formula is: when the load weighting value is larger (namely the clothes amount is larger), the value of T _ comp is larger, and vice versa, the value is smaller; the value of T _ comp is larger when the turbidity weighting value is larger (i.e., the turbidity of the washing object is larger), and is smaller otherwise. In addition, when the load weight value is small and the turbidity weight value is large, T _ comp also takes into account the time slice of decreasing/increasing due to the load being smaller/larger, and takes into account the time slice of increasing/decreasing due to the turbidity being larger/smaller.
206: and judging whether the calculated time segment number is in a valid range or not, and determining the actual time segment number.
Specifically, the method comprises the following steps: the result of T _ comp is compared with the upper and lower limits of the preset washing time slice to determine whether it is within the valid range. If the value is within the valid range, T _ comp is assigned to the actual washing time T, and if the value is not within the valid range, T _ pre is assigned to the actual washing time T. This step is used to limit the uncertainty of the calculated T _ comp, ensuring that the washing program will run using the T _ pre preset washing time segment when the T _ comp is too much or too little washing time segment. It will be understood by those skilled in the art that when the calculation formula is fixed, the reasons for the too low or too high value of T _ comp are the laundry weight W and the water turbidity value D, so those skilled in the art can also limit the range of the calculation result of T _ comp by mathematically limiting the magnitude of the load weight value and the turbidity weight value.
208: and setting the number T of the segments in the actual time and setting the segment rotation-stop ratio R as a preset value.
210: washing is carried out with a fragment spin-to-stop ratio R. Wherein the water turbidity value D and the motor current value I are continuously detected and stored.
212: after the washing of the current time slice is completed, the slice rotation-stop ratio R is updated, and the actual time slice number T is updated (i.e., T ═ T-1). Wherein the spin-to-stop ratio for the next time segment is calculated based on the collected data set and the spin-to-stop ratio is ensured to be within a suitable range.
214: judging whether T is equal to 0, if so, ending the washing program; if not, then go to step 210. Of course, if the current time segment is determined to be the last time segment in step 212, then the update calculation of the segment stop-and-go ratio R may not be required.
With respect to 208-214, specifically: after the water injection is completed, the washing program sets an actual washing time segment T and starts washing for a first time segment at a preset rotation-stop ratio R. And continuously monitoring the water turbidity value D and the motor current value I when the washing is carried out in the first time segment, and continuously sampling and storing the D and the I to obtain a data set of the D and the I in the washing time segment. The washing effect and the motor operating state can be analyzed based on the average value, the trend of the time change, the fluctuation size, etc. of the two data sets, so that the stop-and-go ratio of the next segment can be adjusted. The way of adjustment may follow or fuse the following rules: when the growth trend of the water turbidity data set is relatively slow, namely the washing degree is relatively weak, the rotating proportion of the rotating-stopping ratio of the next segment can be properly increased to enhance the washing strength of the next washing segment, and vice versa; secondly, when the average value of the motor current data set is too large, namely the running load of the motor is too high in the washing time segment, the proportion of the next segment to stop is properly increased, and vice versa.
In law r, it is necessary to exclude the case of "spin" in which the clothes have been washed relatively cleanly, resulting in a water turbidity data set that grows relatively slowly without increasing the spin-to-stop ratio. Examples of exclusion methods are as follows:
the method comprises the following steps: whether the "water turbidity data set is relatively slowly growing" is insufficient or the clothes are washed cleanly is distinguished by judging whether the clothes are currently in the second washing segment. For example, if the first n% of the washing fragments are determined to be insufficient, otherwise, the washing fragments are determined to be clean. Where n can be determined from experimental data. For example, n is 30 to 50.
The second method comprises the following steps: comparing the initial washing turbidity value with the average washing turbidity value of the previous washing segment to judge whether the washing degree is insufficient or the clothes are washed cleanly. For example, if the difference between the average turbidity value of the last washing segment and the initial turbidity value is within a set range (i.e. the difference is small), the washing degree is considered to be insufficient, otherwise, the clothes are clean.
It will be appreciated by those skilled in the art that whether method one, method two, other similar methods, or a combination of methods are used, it is possible to adjust by parameters (e.g., the aforementioned D, I, T and its statistical parameter values, including but not limited to, average values, trends over time, magnitude of fluctuations, valid values, etc.) to determine a turn-to-stop ratio adjustment logic or condition that will achieve the appropriate effect.
And (4) comprehensively analyzing according to the collected data groups of D and I by combining the first rule and the second rule to obtain a segment rotation-stop ratio R which gives consideration to both the cleaning degree and the service life of the motor. And then, performing range judgment on the calculated rotation-stop ratio to ensure that the rotation-stop ratio is within a controllable working range (upper limit) of the motor and within a working range (lower limit) in which the washing is effective, and performing relative adjustment on the rotation-stop ratio of the fragments which are not within the range (for example, adjusting the rotation-stop ratio of the fragments which are lower than the lower limit to a value which at least meets the requirement of the lower limit, and adjusting the rotation-stop ratio of the fragments which are higher than the upper limit to a value which does not exceed the requirement of the upper limit at the highest) to ensure the effectiveness of the washing and the controllability of the motor under the rotation-stop ratio of the fragments.
The water turbidity data set and the motor current data set collected for each time slice may be stored for later analysis in the time slice. According to the analysis of the change of the previous time segment data set, the saturation trend of the water turbidity value and the fluctuation degree of the motor current under different rotation-stop ratios can be obtained, and the D and I data sets of the current washing segment are integrated to calculate a more proper segment rotation-stop ratio so as to optimize the rotation-stop ratio of the next washing time segment.
As regards the turbidity D of the washing water. In one wash, D should be a gradual saturation trend from low values to high values over time. Assuming that at a time T-14 in a washing process with T-15, there may be two sets of turbidity values D15 and D14 in different time slices, and thus the change magnitude of D can be determined, and when T-13 is reached, there may be three sets of turbidity values D15, D14 and D13, and it can be determined that the change trend of D is too fast or too slow.
With respect to the motor current I. In one washing, I should fluctuate constantly, and if the relation between I and R is independently referred, R is increased and I is also increased, but R is not the only influence factor on I, and I is influenced by a plurality of factors such as load distribution of clothes in the drum, the heating degree of a motor, the amount of washing water and the like. The I data set of the previous time slice was collected by the same method as D above.
The average value, derivative and the like can be analyzed for the turbidity D to judge the curve variation trend, and the motor current I can be an effective value which is analyzed for the root mean square, integral, the fluctuation degree in units and the like of the data set to judge the motor current in actual operation. For example, when T is 13, the trend of D15, D14, D13 and the effective values of I15, I14, and I13 can be determined to determine the R of the next time segment. And specific time for increasing R and time for decreasing R can be determined according to the debugging parameters of the actual situation.
By adopting the method embodiments or the implementation mode thereof, the invention provides a method for carrying out washing control by taking washing effect and/or motor service life into consideration. Based on the method, at least one of the following can be achieved: the motor loss of the washing machine is reduced, and the service life of the washing machine is prolonged; the washing time when the clothes are too little is reduced, and the electric energy is saved; when the clothes are too much, the washing cleanliness and the motor loss are balanced.
Fig. 3 is a schematic block diagram of a control device of a washing apparatus according to an embodiment of the present invention, and referring to fig. 3, the control device of the washing apparatus includes an operation parameter obtaining module, a control module, and an operation parameter confirming module. The details will be described below.
In this embodiment, the working parameter obtaining module is configured to obtain the working parameters corresponding to the current time slice in time slices in a washing process, where the washing process includes a plurality of time slices.
