[0028] See also Figure 1 , Figure 1 It is a flow chart of the clothing washing control method provided by an embodiment of the present invention. The clothing washing control method of the embodiment of the present invention can be applied to a washing machine, for example, by configuring a software program corresponding to the washing machine to implement the clothing washing control method, thereby improving the accuracy of clothing cleaning judgment and the clothing cleaning effect. Specifically, in this embodiment, the washing machine includes an inner drum, and a data acquisition device is provided on the drum wall of the inner drum, and the data acquisition device does not block the drainage hole, and the data acquisition device is used to collect the reflectivity of the clothing surface. The clothing washing control method is described in detail below. Figure 1 As shown, the method includes the following steps S110-S130.

[0029] S110 , controlling the inner cylinder to rotate, and performing eccentricity detection on the inner cylinder to obtain an eccentricity detection value.

[0030] In an embodiment of the present invention, when clothes are placed in a washing machine and the washing process is started, the inner drum is first controlled to rotate. Specifically, the inner drum is controlled to rotate at a low acceleration and an appropriate speed to spread the clothes. Spreading the clothes is to facilitate accurate collection of the reflectivity of the clothes surface, and the reflectivity of the clothes surface can reflect the degree of dirtiness of the clothes. After controlling the rotation of the inner drum, the inner drum is eccentricity detected to obtain an eccentricity detection value. Specifically, when the speed of the inner drum is stable, the maximum and minimum values ​​of the motor speed when the inner drum rotates one circle are obtained to obtain the maximum speed value and the minimum speed value; the eccentricity detection value is calculated based on the maximum speed value, the minimum speed value, the preset eccentricity coefficient, and the preset offset. For ease of understanding, it is assumed that the maximum speed value, the minimum speed value, the preset eccentricity coefficient, and the preset offset are ωmax, ωmin, A, and B, respectively, and the eccentricity detection value is the OOB value. The OOB value is calculated based on ωmax, ωmin, A, and B using formula (1). It can be understood that A and B are constants related to the motor, which are set according to actual needs and are not specifically limited here.

[0031] OOB value=A*(ωmax-ωmin)+B (1)

[0032] It should be noted that, in this embodiment, eccentricity detection is also referred to as imbalance detection or OOB detection, and the eccentricity detection value is also referred to as OOB value. For the convenience of description, eccentricity detection will be referred to as OOB detection, and the eccentricity detection value will be referred to as OOB value in the following text. The OOB value is a numerical value that reflects the uniformity of the clothes in the washing machine. It should also be noted that, in this embodiment, because the clothes in the washing machine are not completely evenly spread out, the eccentric mass (uneven part) rises and falls in the drum during the process of one rotation of the inner drum, causing speed fluctuations. OOB detection is to detect the difference in motor speed when the speed of the inner drum is stable. It can be understood that the smaller the OOB value, the more uniform the distribution of clothes, and conversely, the larger the OOB value, the more uneven the distribution of clothes.

[0033] S120. Collecting the reflectivity of the clothing surface through the data acquisition device according to the eccentricity detection value and the preset number of operations to obtain multiple clothing reflectivities, wherein the clothing reflectivity includes a first clothing reflectivity before washing and a second clothing reflectivity after washing.

[0034] In an embodiment of the present invention, after the eccentricity detection is performed on the inner drum to obtain the eccentricity detection value, the reflectivity of the surface of the clothes is collected by the data acquisition device according to the eccentricity detection value and the preset number of operations to obtain a plurality of first reflectivities of the clothes before washing and a plurality of second reflectivities of the clothes after washing. The data acquisition device is an optical sensor; specifically, Figure 2As shown, step S120 may specifically include steps S121-S125: S121: Determine whether the eccentricity detection value is less than or equal to a preset eccentricity detection value. If the eccentricity detection value is less than or equal to the preset eccentricity detection value, execute step S122; otherwise, execute step S124; S122: Obtain the clothing reflectivity based on the reflectivity of the clothing surface collected by the optical sensor, and control the inner drum to stop rotating; S123: Obtain the current number of operations and update the current number of operations. A plurality of clothing reflectivities are obtained based on the updated current number of operations and the preset number of operations; S124: Control the inner drum to stop rotating and obtain the current number of operations; S125: Use the current number of operations as the updated current number of operations and execute the step of determining whether the updated current number of operations is less than the preset number of operations. It is understood that the optical sensors are evenly distributed on the washing machine door seal. It should be noted that in this embodiment, the optical sensors include an optical transmitter and an optical receiver. When the optical transmitter in the optical sensor emits white light onto clothing, the stains on the clothing absorb the light, and the light reflected back to the optical receiver will be attenuated to a certain extent. The reflectivity on the clothing surface is obtained by the change in light intensity before and after reflection. After washing, the stains on the clothing surface are reduced, and the absorption of light will be reduced, thereby increasing the intensity of the reflected light. It should also be noted that in this embodiment, the optical transmitter is mainly used to convert electrical signals into optical signals, and its core component is a semiconductor laser. The optical receiver is mainly used to convert the received optical signal into an electrical signal, which is then further decoded and processed, and its core component is a photodiode.

[0035] For ease of understanding, assume that the preset eccentricity detection value is a preset OOB value. A determination is made as to whether the OOB value is less than or equal to the preset OOB value. If the OOB value is less than or equal to the preset OOB value, indicating that the laundry in the inner drum is evenly spread, steps S122 and S123 are executed to collect the reflectivity of the laundry surface and update the current run count. Conversely, if the OOB value is greater than the preset OOB value, indicating that the laundry eccentricity is large, the laundry is not spread out, and the detectable laundry surface area is small, steps S124 and S125 are executed. That is, when the OOB value is greater than the preset OOB value, the current run count is not updated. It should be noted that in this embodiment, after completing an eccentricity detection, if the OOB value is greater than the preset OOB value, the inner drum is stopped to loosen the laundry, the speed is increased to adjust the laundry, and the next eccentricity detection is performed at a stable speed until the OOB value is less than or equal to the preset OOB value, indicating that the laundry is well spread out. It can be understood that in this embodiment, the spread of the laundry can be determined by determining the magnitude of the OOB value.

[0036] Furthermore, the data acquisition device is an optical sensor; step S123 specifically comprises: determining whether the updated current running count is less than the preset running count; if so, returning to the steps of controlling the inner drum to rotate and detecting eccentricity of the inner drum to obtain an eccentricity detection value, until the updated current running count is not less than the preset running count, thereby obtaining a plurality of clothing reflectances. It should be noted that in this embodiment, after the optical sensor collects the reflectance of the clothing surface once, the inner drum is controlled to stop rotating, and then the current running count is obtained and updated. Based on the updated current running count, the reflectance of the clothing surface is collected multiple times to obtain a plurality of clothing reflectances. The preset running count is 6; in other embodiments, the preset running count can be set according to actual needs. It should also be noted that in this embodiment, the initial value of the current running count is 0; the collection of the reflectance of the clothing surface is repeated five times to better record the contamination of each surface of the clothing.

[0037] Furthermore, since the process of collecting the reflectivity of the clothing surface before and after washing is the same, both include the above-mentioned steps S110 and S120. For the convenience of distinction, the clothing reflectivity obtained before washing is called the first clothing reflectivity, and the clothing reflectivity obtained after washing is called the second clothing reflectivity.

[0038] S130. Determine whether the clothes are clean based on the multiple first clothes reflectivity and the multiple second clothes reflectivity.

[0039] In the embodiment of the present invention, after obtaining the plurality of first clothing reflectivities and the plurality of second clothing reflectivities, it is determined whether the clothing is clean based on the plurality of first clothing reflectivities and the plurality of second clothing reflectivities. Figure 3As shown, step S130 may specifically include steps S131-S133: S131, calculating the average of multiple reflectivities of the first clothes to obtain a first average reflectivity; S132, calculating the average of multiple reflectivities of the second clothes to obtain a second average reflectivity; S133, judging whether the clothes are clean based on the first average reflectivity and the second average reflectivity. Specifically, step S133 specifically includes: calculating the difference between the first average reflectivity and the second average reflectivity to obtain a reflectivity difference; if the reflectivity difference is greater than or equal to a preset reflectivity difference, judging that the clothes are clean; if the reflectivity difference is less than the preset reflectivity difference, judging that the clothes are not clean. More specifically, for ease of understanding, assume that the reflectivity of the first clothes is R1i, i = 1, 2, 3, 4, 5; the reflectivity of the second clothes is R2j, j = 1, 2, 3, 4, 5; the first average reflectivity and the second average reflectivity are R1 and R2 respectively; the preset reflectivity difference is ΔR0, and the reflectivity difference is ΔR; R1 = (R11 + R12 + R13 + R14 + R15) / 5, R2 = (R21 + R22 + R23 + R24 + R25) / 5, ΔR = R1 - R2, if ΔR ≥ ΔR0, it means that the stain removal effect is good, and the clothes are determined to be clean; if ΔR < ΔR0, it means that the stain removal effect is poor, and the clothes are determined to be not clean. It should be noted that in this embodiment, if the clothes are determined to be not clean, the washing process is adjusted to continue washing; if the clothes are determined to be clean, the washing process is controlled to end.

[0040] Figure 4 A simplified flow chart of a method for controlling laundry washing provided by an embodiment of the present invention is shown in FIG. Figure 4 As shown, the clothes are placed and the pre-washing detection process is started; the inner drum rotates at a low acceleration and an appropriate speed to spread out the clothes, and the OOB value is used to judge whether the clothes are spread out; the reflectivity of the surface of the clothes before washing is measured multiple times to obtain multiple first clothes reflectivities; the washing process is entered; the reflectivity of the surface of the clothes after washing is measured multiple times to obtain multiple second clothes reflectivities; the average values ​​of the multiple first clothes reflectivities and the multiple second clothes reflectivities are calculated respectively to obtain a first average reflectivity and a second average reflectivity; the difference between the first average reflectivity and the second average reflectivity is calculated to obtain a reflectivity difference ΔR, and it is judged whether ΔR ≥ a preset reflectivity difference ΔR0; if ΔR ≥ ΔR0, it is determined that the clothes have been washed and the washing is ended; if ΔR < ΔR0, it is determined that the clothes have not been washed and the washing process needs to be adjusted to continue washing.

[0041] Figure 5 A detailed flow chart of a method for controlling laundry washing provided by an embodiment of the present invention is shown in FIG. Figure 5As shown, S0: Place the clothes and start the pre-washing detection process; S1: The inner drum rotates at a low acceleration and an appropriate speed to spread the clothes; S2: OOB detection obtains the OOB value; S3: Determine whether the OOB value is ≤ the preset OOB value; If the OOB value is ≤ the preset OOB value, execute step S4; Otherwise, execute S5; S4: The optical sensor collects the reflectivity of the clothing surface to obtain the first clothing reflection list R1i. It is understandable that the current number of runs will also be updated; S5: Control the inner drum to stop rotating to let the clothes scatter so that the clothing surface can be converted for reflectivity collection; S6: Determine whether the current number of runs is < the preset number of runs; If the current number of runs is < the preset number of runs, return to execution Step S1; otherwise, execute step S7; S7: enter the washing process; S8: repeat the pre-washing detection process after washing is completed, first let the inner drum rotate at a low acceleration and appropriate speed to spread the clothes; S9: OOB detection to obtain the OOB value; S10: determine whether the OOB value is ≤ the preset OOB value; if the OOB value is ≤ the preset OOB value, execute step S11; otherwise, control the inner drum to stop rotating and readjust until the clothes are sufficiently spread out; S11: the optical sensor collects the reflectivity of the clothing surface to obtain a second clothing reflection list R2j. It is understandable that the current number of operations will also be updated; S12: control the inner drum to stop rotating to allow the clothes to scatter so that the clothing surface can be converted for reflectivity collection;

[0042] S13: Determine whether the current number of runs is less than the preset number of runs; if the current number of runs is less than the preset number of runs, return to execute step S8; otherwise, execute step S14; S14: Calculate the average values ​​of Ri and Rj respectively to obtain R1 and R2, and calculate the difference between R1 and R2 to obtain the reflectivity difference ΔR; S15: Determine whether ΔR is greater than or equal to the preset reflectivity difference ΔR0; if ΔR is greater than or equal to ΔR0, it is determined that the clothes have been washed and the washing is ended; if ΔR is less than ΔR0, it is determined that the clothes have not been washed and the washing process needs to be adjusted to continue washing.

[0043] To sum up, by performing eccentricity detection on the inner drum to obtain the eccentricity detection value, it is possible to determine whether the clothes are spread evenly; by collecting the reflectivity of the clothing surface through the optical sensor, multiple first clothing reflectivities before washing and multiple second clothing reflectivities after washing are obtained, and whether the clothes are clean is determined based on the multiple first clothing reflectivities and the multiple second clothing reflectivities after washing, rather than measuring the reflectivity of the washing water, which greatly improves the accuracy of the judgment on whether the clothes are clean and the clothing cleaning effect.
