Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment, and in particular, relates to a turbidity detection and rinsing control method for a washing device and the washing device. Background Art

[0002] "Washing equipment" refers to a general term for a type of household appliances that can perform washing, dehydration and other programs, such as washing machines, washer-dryers, etc.

[0003] At present, washing equipment generally determines the required amount of detergent by the weight and number of items to be washed, so as to achieve quantitative delivery of detergent. However, since the detergents on the market include ordinary and concentrated types with different concentrations, and the effective active ingredients of different detergents are also different, it is impossible to accurately deliver the right amount of detergent using only this method. If the amount of detergent is too much, it will lead to more residual detergent, more rinsing times, and more water consumption; on the other hand, if the amount of detergent is too little, it will lead to problems such as incomplete washing, affecting the user experience.

[0004] In response to the above problems, some washing equipment currently detects the turbidity value of the washing water to further accurately determine the content of detergent in the washing water; the detection method is as follows:

[0005] Method 1: Use a spectral turbidity detector for detection. The principle is to use light scattering to measure suspended particles in the water. When light passes through particles in the water, the light will be scattered. The intensity of the scattered light is proportional to the turbidity of the washing water within a certain range. However, once there are impurities in the washing water that cannot be discharged from the washing machine, the accuracy of the turbidity detection will be greatly reduced.

[0006] Method 2: Use a conductivity turbidity detector for detection. The principle is to use two plates and increase the voltage in the middle. The current loss is the turbidity of the washing water. However, the conductivity of water will show great differences at different temperatures, which will seriously affect the accuracy of turbidity detection. The dirt accumulated in the water will also reduce the accuracy of turbidity detection.

[0007] Method 3: Use a TOC turbidity detector for detection. However, when using inorganic detergents, this detector will be completely ineffective. When using detergents with low organic content, the accuracy of this method of detection is also extremely low.

[0008] In view of this, the present invention is proposed. Summary of the invention

[0009] An object of the present invention is to provide a method for detecting the turbidity of washing water in a washing device, so as to achieve the purpose of accurately detecting the turbidity of washing water.

[0010] Another object of the present invention is to provide a rinsing control method for a washing machine, so as to achieve the purpose of accurately controlling the number of rinses and improving the rinsing efficiency and rinsing effect.

[0011] Another object of the present invention is to provide a washing device to achieve the purpose of accurately controlling the rinsing program according to accurate turbidity information of the washing water, improving the rinsing effect, and enhancing the user experience.

[0012] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0013] A method for detecting turbidity of washing water in a washing device, the washing device comprising a barrel body for containing washing water, obtaining a weight value R corresponding to the current cleanliness of the inner wall of the barrel body, detecting the turbidity value Q of the washing water in the barrel body, and using the obtained weight value R to correct the detected turbidity value Q.

[0014] Further, using the weight value R to correct the turbidity value Q includes: Preset calculation formula Q 修正 =Q*R, the obtained weight value R and the detected turbidity value Q are substituted into the preset calculation formula to obtain the corrected turbidity value of the washing water.

[0015] Furthermore, the washing device includes a self-cleaning program for cleaning the barrel.

[0016] Obtaining the weight value R corresponding to the current cleanliness of the inner wall of the barrel includes: obtaining the interval time P from the end of the last self-cleaning program to the current time, different interval times have corresponding weight values ​​R, and selecting the weight value R corresponding to the current interval time P as the weight value R corresponding to the current cleanliness of the inner wall of the barrel.

[0017] Furthermore, the weight value R is negatively correlated with the interval time P.

[0018] Furthermore, the temperature value T of the washing water in the barrel is detected, and the weight value R' corresponding to the detected temperature value T is obtained, and the detected turbidity value Q is corrected using the obtained weight value R and the weight value R'.

[0019] Furthermore, using the weight value R and the weight value R' to correct the detected turbidity value Q includes: using fuzzy comprehensive evaluation to establish a mathematical model based on the weight value R, the weight value R' and the turbidity value Q, bringing the obtained turbidity values ​​Q into the mathematical model, and correcting the detected turbidity value Q.

[0020] Furthermore, a weight matrix A including weight values ​​R and weight values ​​R' is established, and the turbidity values ​​Q of several washing waters are detected and established as a fuzzy comprehensive judgment matrix R. The comprehensive evaluation matrix B is obtained through fuzzy synthesis calculation of the weight matrix A and the fuzzy comprehensive judgment matrix R, which is a data set of corrected turbidity values ​​Q, and the maximum value in the data set is taken as the corrected turbidity value.

[0021] Further, detecting the turbidity value Q of the washing water in the barrel includes: detecting the TOC value of the washing water in the barrel, using the detected TOC value as the turbidity value Q, and / or detecting the turbidity value Q using an optical turbidity detector.

[0022] The present invention also provides a rinsing control method for a washing device. During the rinsing process, a turbidity value Q0 is preset, and the turbidity of the washing water is detected by any detection method described in the above technical scheme. If the detected turbidity is greater than the preset turbidity value Q0, the rinsing is controlled to continue.

[0023] The present invention also provides a washing device which is controlled by any control method described in the above technical solutions.

[0024] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0025] In the present invention, when the cleanliness of the inner wall of the barrel of the washing equipment is different, the corresponding weight value is also different. After the turbidity value of the washing water is detected, the corresponding weight value is selected to correct the detected turbidity value according to the current cleanliness of the inner wall of the barrel, thereby overcoming the interference of the cleanliness of the inner wall of the barrel on the turbidity detection result, so that the corrected turbidity value can fully represent the actual turbidity of the washing water in the barrel, and the detection result is accurate and reliable.

[0026] In the rinsing control method of the washing equipment of the present invention, the corrected turbidity value is used as the actual turbidity of the washing water during the rinsing process. The progress of the rinsing program can be accurately controlled according to the corrected turbidity value, which not only ensures that the clothes can be rinsed clean, but also avoids excessive rinsing times and the waste of water and electricity resources.

[0027] The washing device of the present invention accurately controls the rinsing procedure according to the turbidity information of the washing water, thereby improving the rinsing effect and enhancing the user experience.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] "Washing equipment" refers to a general term for a type of household appliances that can perform washing, dehydration and other procedures, such as washing machines, washer-dryers, etc. The washing equipment includes a barrel for containing washing water.

[0038] The present invention provides a method for detecting turbidity of washing water in a washing device, comprising: obtaining a weight value R corresponding to the current cleanliness of the inner wall of a barrel body, detecting a turbidity value Q of the washing water in the barrel body, and correcting the detected turbidity value Q using the obtained weight value R.

[0039] The cleanliness of the inner wall of the barrel represents the degree of dirtiness of the barrel. If the cleanliness of the inner wall of the barrel is high, it will interfere less with the result of turbidity detection, and the detected turbidity value Q will be more accurate. On the contrary, if the cleanliness of the inner wall of the barrel is low, it will interfere more with the result of turbidity detection, and the detected turbidity value Q will be inaccurate. According to different cleanliness of the inner wall of the barrel, the present invention sets a corresponding weight value R, selects the corresponding weight value R according to the obtained cleanliness of the inner wall of the barrel, and corrects the detected turbidity value Q.

[0040] Specifically, Figure 1 As shown, the control steps include:

[0041] S1, start;

[0042] S2. Obtain the weight value R corresponding to the current cleanliness of the inner wall of the barrel;

[0043] S3, detecting the turbidity value Q of the washing water in the barrel;

[0044] S4. Correct the detected turbidity value Q using the acquired weight value R;

[0045] S5. Using the corrected turbidity value as the actual turbidity of the washing water;

[0046] S6, determine whether the set detection time has been reached, if so, execute step S7; otherwise, return to step S3;

[0047] S7. End.

[0048] In the present invention, when the cleanliness of the inner wall of the barrel of the washing equipment is different, the corresponding weight value is also different. After the turbidity value of the washing water is detected, the corresponding weight value is selected to correct the detected turbidity value according to the current cleanliness of the inner wall of the barrel, thereby overcoming the interference of the cleanliness of the inner wall of the barrel on the turbidity detection result, so that the corrected turbidity value can fully represent the actual turbidity of the washing water in the barrel, and the detection result is accurate and reliable.

[0049] As an embodiment of the present invention, using the weight value R to correct the turbidity value Q includes: a preset calculation formula Q 修正 =Q*R, substitute the obtained weight value R and the detected turbidity value Q into the preset calculation formula to obtain the corrected turbidity value of the washing water. Wherein, the weight value 0<R<1; for example: if the weight value R is 1 / 7, and the detected turbidity value is Q, the corrected turbidity value is 1 / 7*Q.

[0050] Preferably, the weight value R in this embodiment can be obtained by summarizing historical experience values, as illustrated below:

[0051] S1. Obtain the cleanliness of the inner wall of the barrel;

[0052] S2. Use the turbidity sensor to detect the turbidity value Q of the washing water in the barrel 00 ;

[0053] S3. After the test is completed, the washing water is discharged and the turbidity value Q of the washing water is obtained again in the drainage pipe. 01 , Q 01 / Q 00 As the weight value R corresponding to the current cleanliness.

[0054] In this embodiment, the turbidity value Q is corrected by using the weight value R so that the corrected turbidity value can accurately represent the actual turbidity of the washing water. The weight value R can be corrected according to the user's historical detection conditions to ensure the accuracy of the turbidity detection results at different use stages.

[0055] As an embodiment of the present invention, the washing device includes a self-cleaning program for cleaning the barrel. When the self-cleaning program is turned on, the washing device can self-clean the barrel to ensure the cleanliness of the inner wall of the barrel.

[0056] The present embodiment provides a method for obtaining a weight value R corresponding to the cleanliness of the inner wall of a barrel, which is specifically as follows: obtaining the interval time P from the end of the last self-cleaning program to the current time, different interval times have corresponding weight values ​​R, and selecting the weight value R corresponding to the current interval time P as the weight value R corresponding to the current cleanliness of the inner wall of the barrel.

[0057] Specifically, Figure 2 As shown, the control steps include:

[0058] S1, start;

[0059] S2, obtaining the interval time P from the end of the last self-cleaning program to the current one;

[0060] S3, selecting a weight value R corresponding to the current interval time P;

[0061] S4, detecting the turbidity value Q of the washing water in the barrel;

[0062] S5. Substitute the obtained weight value R and the detected turbidity value Q into the preset calculation formula Q 修正 =Q*R;

[0063] S6. The calculated Q 修正 As the actual turbidity of the wash water;

[0064] S7, determine whether the set detection time has been reached, if so, execute step S8; otherwise, return to step S4;

[0065] S8. End.

[0066] In this embodiment, the longer the interval time P from the end of the last self-cleaning program to the current one, the longer the barrel body has not been cleaned, and the lower the cleanliness of the inner wall of the barrel body. On the contrary, the shorter the interval time P from the end of the last self-cleaning program to the current one, the more recently the barrel body has been cleaned, and the higher the cleanliness of the inner wall of the barrel body.

[0067] As an implementation of this embodiment, the weight value R is negatively correlated with the interval time P. In this implementation, the longer the interval time P is, the lower the cleanliness of the inner wall of the barrel body is, the greater the interference to the detected turbidity value of the washing water is, and the detected turbidity value is much higher than the actual turbidity value of the washing water. At this time, the corresponding weight value R is controlled to be smaller, so that the corrected turbidity value is closer to the actual turbidity value of the washing water.

[0068] As an embodiment of the present invention, a camera device is provided on the washing device for obtaining a picture of the inner wall of the barrel body, and judging the cleanliness of the inner wall of the barrel body according to the obtained picture. Specifically, the washing device pre-stores a reference picture of the inner wall of the barrel body in a clean state, obtains a picture of the inner wall of the barrel body before water is added to the barrel body, and compares the obtained picture with the reference picture to obtain the cleanliness of the current inner wall of the barrel body.

[0069] This embodiment provides a method for obtaining the cleanliness of the inner wall of the barrel. The method is simple and convenient for accurately obtaining the actual condition of the inner wall of the barrel.

[0070] As an embodiment of the present invention, the temperature value T of the washing water in the barrel is detected, and the weight value R' corresponding to the detected temperature value T is obtained, and the obtained weight value R and the weight value R' are used to correct the detected turbidity value Q. The washing device is provided with a temperature sensor, and the temperature sensor is controlled to turn on and detect the temperature value T of the washing water in the barrel.

[0071] The higher the temperature of the washing water, the more likely it is that the anions and cations in the washing water will interact with each other and precipitate, which will further make the washing water turbid, which will interfere with the actual turbidity detection result. In this embodiment, a weight value corresponding to the temperature of the washing water is preset, and the detected turbidity value is corrected to overcome the interference of temperature on the turbidity detection result, so that the corrected turbidity value can fully represent the actual turbidity of the washing water in the barrel, and the detection result is accurate and reliable.

[0072] As an implementation method of this embodiment, using the weight value R and the weight value R' to correct the detected turbidity value Q includes: using fuzzy comprehensive evaluation to establish a mathematical model based on the weight value R, the weight value R', and the turbidity value Q, bringing the obtained turbidity values ​​Q into the mathematical model, and correcting the detected turbidity value Q

[0073] Furthermore, a weight matrix A including weight values ​​R and weight values ​​R' is established, and the turbidity values ​​Q of several washing waters are detected and established as a fuzzy comprehensive judgment matrix R. The comprehensive evaluation matrix B is obtained through fuzzy synthesis calculation of the weight matrix A and the fuzzy comprehensive judgment matrix R, which is a data set of corrected turbidity values ​​Q, and the maximum value in the data set is taken as the corrected turbidity value.

[0074] Specifically, the control steps include:

[0075] S1, start;

[0076] S2. Obtain the weight value R corresponding to the current cleanliness of the inner wall of the barrel;

[0077] S3, detecting the temperature value T of the washing water in the barrel;

[0078] S4, obtaining a weight value R' corresponding to the detected temperature value T;

[0079] S5, establishing a weight matrix A including weight values ​​R and weight values ​​R';

[0080] S6. Detecting several turbidity values ​​Q of the washing water; preferably, detecting several turbidity values ​​Q during the rinsing process;

[0081] S7, establishing a fuzzy comprehensive judgment matrix R based on a number of turbidity values ​​Q;

[0082] S8, obtaining a comprehensive evaluation matrix B by fuzzy synthesis calculation of the weight matrix A and the fuzzy comprehensive judgment matrix R, which is a data set of the corrected turbidity value Q;

[0083] S9, selecting the maximum value in the data set as the corrected turbidity value;

[0084] S10, determine whether the set detection time has been reached, if so, execute step S11; otherwise, return to step S3;

[0085] S11. End.

[0086] Further specific examples are given below:

[0087] Establish a comprehensive evaluation factor set: Factor set U = (the turbidity result Q detected by the optical turbidity detector 光 、TOC turbidity tester turbidity result Q TOC , temperature, cleanliness of the inner wall of the barrel);

[0088] Determine the review set as V = (extremely poor, poor, good, excellent);

[0089] Taking the analytic hierarchy process as an example, the 1-7 scaling method is used to compare each evaluation index in pairs to obtain the judgment matrix of the evaluation index. The scaling table is shown in Table 1 below;

[0090] Table 1:

[0091]

[0092] According to the meaning in the above table, the turbidity result Q detected by the optical turbidity detector is the evaluation index 光 、TOC turbidity tester turbidity result Q TOC , temperature, and the cleanliness of the inner wall of the barrel are compared in pairs to obtain a 4*4 square matrix table, as shown in Table 2 below, where the data in the table are obtained by random assignment;

[0093] Table 2:

[0094]

[0095] Normalize the data in the above table by column, calculate the normalized vector of each column by formula, and calculate the judgment matrix as follows:

[0096]

[0097] After finding the average value according to the rows in the judgment matrix, we get the weight matrix A: (0.427, 0.427, 0.079, 0.073);

[0098] Detect several turbidity values ​​Q of washing water and arrange them into a 4-row n-column fuzzy comprehensive judgment matrix R.

[0099]

[0100] Through fuzzy transformation, the fuzzy synthesis calculation of the weight matrix A and the fuzzy comprehensive judgment matrix R is used to obtain a 1-row n-column comprehensive evaluation matrix B = (b1, b2...bn); wherein the calculation method is as follows:

[0101] b1=0.427*Q11+0.427*Q21+0.079*Q31+0.073*Q41;

[0102] b2=0.427*Q12+0.427*Q22+0.079*Q32+0.073*Q42;

[0103] …

[0104] bn=0.427*Q1n+0.427*Q2n+0.079*Q3n+0.073*Q4n.

[0105] The comprehensive evaluation matrix B is used as the data set of the corrected turbidity value Q, and the maximum value in the data sets b1, b2...bn is used as the corrected turbidity value. The corrected turbidity value is subjectively assigned to the scoring interval of the comment set V = (extremely poor, poor, good, excellent).

[0106] The present invention uses a fuzzy comprehensive evaluation method to reasonably correct the turbidity of the washing water according to the weight of the temperature of the washing water and the cleanliness of the inner wall of the barrel, and the corrected turbidity can accurately represent the actual turbidity of the current washing water. The detection method of the present invention is an analysis method based on big data, which can be implemented on the memory and processor of the washing equipment.

[0107] As an embodiment of the present invention, detecting the turbidity value Q of the washing water in the barrel body includes: using a TOC turbidity detector to detect the TOC value of the washing water in the barrel body, and using the detected TOC value as the turbidity value Q; or, using an optical turbidity detector to detect the turbidity value Q; or, using the above two methods to obtain two turbidity values.

[0108] In this embodiment, different detection methods such as a TOC turbidity detector and an optical turbidity detector are used to detect the turbidity of the washing water, which is conducive to a more comprehensive analysis of the actual turbidity of the washing water, making the corrected washing water turbidity more accurate and reliable.

[0109] The present invention also provides a rinsing control method for a washing device. During the rinsing process, a turbidity value Q0 is preset, and the turbidity of the washing water is detected by any detection method described in the above technical scheme. If the detected turbidity is greater than the preset turbidity value Q0, the rinsing is controlled to continue.

[0110] Specifically, Figure 3 As shown, the control steps include:

[0111] S1, start rinsing;

[0112] S2, preset turbidity value Q0;

[0113] S3, obtaining the weight value R corresponding to the current cleanliness of the inner wall of the barrel;

[0114] S4, detecting the turbidity value Q of the washing water in the barrel;

[0115] S5. Correct the detected turbidity value Q using the acquired weight value R;

[0116] S6. Using the corrected turbidity value as the actual turbidity of the washing water;

[0117] S7, determine whether the detected turbidity is greater than the preset turbidity value Q0, if not, execute step S8; if yes, return to step S1;

[0118] S8, rinsing ends.

[0119] In the rinsing control method of the washing equipment of the present invention, the corrected turbidity value is used as the actual turbidity of the washing water during the rinsing process. The progress of the rinsing program can be accurately controlled according to the corrected turbidity value, which not only ensures that the clothes can be rinsed clean, but also avoids excessive rinsing times and the waste of water and electricity resources.

[0120] The present invention also provides a washing device, which is controlled by the control method described in any one of the above technical solutions. Specifically, the washing device includes a processor, a memory, and a computer program stored in the memory and executable on the processor, and the processor implements the control method described in any one of the above technical solutions when executing the program.

[0121] The washing device of the present invention accurately controls the rinsing procedure according to the turbidity information of the washing water, thereby improving the rinsing effect and enhancing the user experience.

[0122] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
