Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smart home appliances, and particularly provides a control method for a washing device and the washing device. BACKGROUND

[0002] A washing machine is a common household laundry washing device. According to the washing method, the washing machine can be roughly divided into a pulsator washing machine and a drum washing machine. Taking the pulsator washing machine as an example, the washing machine first performs fuzzy weighing on the laundry before performing the water injection operation, and then determines the washing water level according to the obtained weight of the laundry. However, when the washing machine performs fuzzy weighing on the laundry, the laundry is assumed to be dry laundry. If the laundry is wet laundry, the obtained weight of the laundry will be much greater than the actual dry weight of the laundry, resulting in a high washing water level and causing waste of water resources.

[0003] In order to solve the above problems, the invention with the publication number CN113463320A discloses a pulsator, a washing machine comprising the same and a control method. The control method specifically includes: when detecting that the laundry to be washed is wet laundry, performing a dehydration operation, obtaining the weight G2 of the laundry after dehydration, and then performing a washing program according to the weight G2 of the laundry; and when detecting that the laundry to be washed is dry laundry, performing a washing program according to the weight G1 of the laundry. However, in actual application, the dehydrated laundry still contains a certain amount of water. Therefore, performing the washing program according to the weight of the dehydrated laundry will still result in a high washing water level, which is not conducive to user experience.

[0004] Therefore, there is a need for a new control method for a washing device and a washing device to solve the above problems. SUMMARY

[0011] In the preferred technical scheme of the control method, the step of "determining the correction coefficient according to the judgment result" specifically includes: if the ratio is greater than or equal to the preset ratio, determining the correction coefficient as a first correction coefficient k1; and if the ratio is less than the preset ratio, determining the correction coefficient as a second correction coefficient k2; wherein the k1 is greater than the k2, and 0.5 < k1 ≤ 1, and k2 ≤ 0.5.

[0012] In the preferred technical solution of the control method, the step of causing the washing device to perform the preset-time spin-drying operation specifically comprises: judging whether the first fuzzy weight is less than a preset weight; if the first fuzzy weight is less than the preset weight, causing the washing device to perform a first-time spin-drying operation; if the first fuzzy weight is greater than or equal to the preset weight, causing the washing device to perform a second-time spin-drying operation; wherein the first time is less than the second time.

[0013] In the preferred technical solution of the control method, the step of selectively causing the washing device to perform the water injection operation according to the first fuzzy weight according to the judgment result specifically comprises: if the absolute value of the first difference is greater than or equal to the preset difference, causing the washing device to perform a segmented water injection operation.

[0015] In the second aspect, the present application provides a washing device, comprising: a processor; a memory for storing a plurality of program codes; the program codes are suitable for being loaded and executed by the processor to implement the control method in any one of the preferred technical solutions.

[0017] Compared with the prior art of performing a water injection operation according to the weight after spin-drying, in the case where it is detected that the laundry is wet laundry, the washing machine is caused to perform a fuzzy weighing operation to obtain a first fuzzy weight; a water level frequency value of the washing machine is obtained; and the water injection level can be accurately determined according to the first fuzzy weight and the water level frequency value, based on which the washing machine is caused to perform a water injection operation, so that the water inlet amount of the washing machine can be accurately controlled, better washing effect is provided for the laundry, water resource waste is avoided, the purpose of providing the most appropriate and effective water injection operation for the washing machine is achieved, and the user experience is improved.

[0033] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that the embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application. For example, although the present application is described in combination with a washing machine, the technical solutions of the present application are not limited thereto, and in actual applications, the washing device can also be any one of a washer-dryer, a steam washing device, a shoe washing machine and the like. Among them, the washing machine can be a pulsator washing machine, a drum washing machine and the like.

[0034] It should be noted that in the description of the present application, the terms "first", "second", "third" are only used for the purpose of description and should not be understood as indicating or implying relative importance.

[0035] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the term "arrangement" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. Those skilled in the art can understand the specific meaning of the above-mentioned terms in the present application according to the specific circumstances.

[0036] Based on the technical problems proposed in the background art, the present application provides a control method for a washing machine, which aims to make the washing machine perform a fuzzy weighing operation to obtain a first fuzzy weight in the case of detecting that the laundry is wet laundry; obtain a water level frequency value of the washing machine; accurately determine the water injection water level according to the first fuzzy weight and the water level frequency value, and based on this, make the washing machine perform a water injection operation, which can accurately control the water inflow of the washing machine and provide better washing effect for the laundry, thereby avoiding waste of water resources, achieving the purpose of providing the most appropriate and effective water injection operation for the washing machine, and improving the user's experience.

[0037] Firstly, referring to Figure 1 , the control method of the present application is described. Among them, Figure 1 is the flow of the control method of the present application Figure 1 .

[0038] As Figure 1 shown, the washing machine comprises a washing tub; the control method of the present application comprises the following steps:

[0039] S100, detecting the dryness of the laundry in the washing tub after the washing machine is started;

[0040] S200, in the case of detecting that the laundry is wet laundry, making the washing machine perform a fuzzy weighing operation to obtain a first fuzzy weight;

[0041] S300, obtaining a water level frequency value of the washing machine;

[0042] S400, according to the first fuzzy weight and the water level frequency value, making the washing machine perform a water injection operation.

[0043] In step S100, the detection circuit is arranged on the impeller of the washing machine, and the detection circuit comprises a plurality of detection contacts which are in contact with the laundry to detect the dryness of the laundry. Alternatively, the detection circuit can also be arranged on the inner wall of the washing tub. The skilled in the art can flexibly adjust and arrange the setting position of the detection circuit, and no matter how the setting position of the detection circuit is adjusted and arranged, as long as the dryness of the laundry can be detected.

[0044] In step S200, the specific steps of making the washing machine perform a fuzzy weighing operation are: making the washing tub rotate, for example, alternating rotation of forward and reverse rotation, or forward rotation, or reverse rotation, so that the laundry in the washing tub is distributed more uniformly, and then performing a weighing operation, so that the obtained first fuzzy weight is more accurate.

[0045] Further, the weight of the laundry is detected by the washing machine, for example, by a weight sensor arranged in the washing machine, or by reading the number of back-EMF pulses generated by the driving motor after the driving motor is rotated to a certain speed and then stopped.

[0046] Further, if the user pours the pre-washing water into the washing tub, the pre-washing water can also move to the outer tub during the rotation of the washing tub, so that the water level is lowered, and thus the water level frequency value of the washing machine can be more accurately obtained.

[0047] In step S300, the water level frequency value can be detected by a water level sensor arranged in the washing machine, simultaneously or after step S200 is performed.

[0048] The control method for performing the water injection operation of the present application will be described below with reference to the accompanying drawings. Figures 2 to 7 The control method for performing the water injection operation of the present application will be described below with reference to the accompanying drawings. Figure 2 is a flowchart of the control method for performing the water injection operation of the present application. Figure 1 ; Figure 3 is a flowchart of the control method for performing the water injection operation of the present application. Figure 2 ; Figure 4 is a flowchart of the control method for performing the water injection operation according to the first fuzzy weight of the present application; Figure 5 is a flowchart of the control method for performing the water injection operation of the present application; Figure 6 is a flowchart of the control method for correcting the second fuzzy weight of the present application; Figure 7 is a flowchart of the control method for determining the correction coefficient of the present application.

[0049] As shown in Figure 2 , the step of "performing the water injection operation of the washing machine according to the first fuzzy weight and the water level frequency value" in step S400 specifically includes:

[0050] S411, calculating a first difference between the water level frequency value and a preset water level frequency value;

[0051] S412, judging whether the absolute value of the first difference is less than a preset difference value;

[0052] S413, selectively performing the water injection operation of the washing machine according to the first fuzzy weight according to the judgment result.

[0053] In step S411, the first difference ΔF is the result of subtracting the preset water level frequency value F0 from the detected water level frequency value F1, i.e., ΔF = F1 - F0; or, the first difference ΔF is the result of subtracting the detected water level frequency value F1 from the preset water level frequency value F0, i.e., ΔF = F0 - F1. Those skilled in the art can determine the specific calculation method of the first difference according to the usage requirements. Therefore, the first difference may be a positive number, zero, or a negative number.

[0054] For example, if the preset water level frequency value F0 is 41500Hz and the water level frequency value F1 detected in step S300 is 41350Hz, then ΔF = 41350Hz - 41500Hz = -150Hz; or, if the preset water level frequency value F0 is 41500Hz and the water level frequency value F1 detected in step S300 is 41450Hz, then ΔF = 41500Hz - 41450Hz = 50Hz.

[0055] In step S412, since the first difference may be positive, zero, or negative, the absolute value of the first difference is compared with the preset difference, which improves the accuracy of the judgment.

[0056] It should be noted that the water level frequency values, the first difference, and the preset water level frequency values ​​listed above are merely illustrative and not restrictive. Those skilled in the art can flexibly adjust and set the preset water level frequency value according to the actual operating conditions of the washing machine, and calculate the first difference based on the actual detected water level frequency value.

[0057] like Figure 3 As shown, step S413, "selectively causing the washing machine to perform a water filling operation based on the first fuzzy weight according to the judgment result," specifically includes:

[0058] S421. If the absolute value of the first difference is greater than or equal to the preset difference, then the washing machine shall perform a segmented water filling operation.

[0059] S422. If the absolute value of the first difference is less than the preset difference, the washing machine is made to perform a water injection operation based on the first fuzzy weight.

[0060] In step S421, if the absolute value of the first difference is greater than or equal to the preset difference, for example, if the preset difference is 100Hz and the calculated first difference is -150Hz, and its absolute value is 150Hz, which is greater than the preset difference, it means that the user not only put wet clothes into the washing tub, but also poured the water for the pre-washed clothes into the washing tub. The first fuzzy weight is the total weight of the wet clothes and the water for the pre-washed clothes. Then the washing machine performs a segmented water injection operation to avoid injecting too much washing water, making the amount of injected washing water more reasonable and further improving the user experience.

[0061] Furthermore, the current water level is determined based on the water level frequency value, and a first target water level is determined based on the current water level. The washing machine is then filled with water up to the first target water level. For example, if the current water level is the first water level and the first target water level is the second water level, the first target water level is higher than the current water level. After a preset time interval (e.g., 10 seconds), the water level frequency value is detected again. It is determined whether the difference between the detected water level frequency value and the previously detected water level frequency value is within a preset deviation range. If so, the washing machine stops filling with water. If not, the washing machine is filled with water up to the second target water level, i.e., the next water level, such as the third water level. The above steps are repeated until the difference between the detected water level frequency value and the previously detected water level frequency value is within a preset deviation range, at which point the washing machine stops filling with water.

[0062] In step S422, if the absolute value of the first difference is less than the preset difference, for example, if the preset difference is 100Hz and the calculated first difference is 50Hz, and its absolute value is 50Hz, which is less than the preset difference, it means that the user only put the wet clothes into the washing tub and did not pour the water for the pre-washed clothes into the washing tub. The first fuzzy weight is the weight of the wet clothes. Then the washing machine performs the water injection operation according to the first fuzzy weight, making the amount of water injected more reasonable and further improving the user experience.

[0063] It should be noted that the first difference and preset difference listed above are merely illustrative and not restrictive. Those skilled in the art can flexibly adjust and set the preset difference according to the actual operating conditions of the washing machine, and calculate the first difference based on the actual detected water level frequency value.

[0064] It should also be noted that in the above process, steps S421 and S422 are not sequential but parallel, and are only related to the judgment result of whether the absolute value of the first difference is less than the preset difference. The corresponding steps can be executed according to different judgment results.

[0065] like Figure 4 As shown, step S422, the step of "causing the washing machine to perform a water filling operation based on the first fuzzy weight" specifically includes:

[0066] S431. Cause the washing machine to perform a preset time spin-drying operation;

[0067] S432. After the washing machine performs the spin-drying operation, the washing machine performs the fuzzy weighing operation again to obtain the second fuzzy weight.

[0068] S433. Correct the second fuzzy weight based on the first fuzzy weight to obtain the corrected weight of the second fuzzy weight;

[0069] S434. Determine the first inlet water level based on the corrected weight;

[0070] S435, making the washing machine perform a water filling operation according to the first water filling level.

[0071] As shown in FIG. 4, the step S431 of "making the washing machine perform a preset-time dewatering operation" specifically includes: Figure 5

[0072] S441, judging whether the first fuzzy weight is less than a preset weight; if yes, performing step S442; if no, performing step S443;

[0073] S442, making the washing machine perform a first-time dewatering operation;

[0074] S443, making the washing machine perform a second-time dewatering operation;

[0075] wherein the first time is less than the second time.

[0076] In step S442, if the first fuzzy weight is less than the preset weight, for example, the preset weight is 4 kg and the detected first fuzzy weight is 3 kg, which is less than the preset weight, it indicates that the first fuzzy weight is light and a shorter time can be used to spin dry the laundry, and thus the washing machine is made to perform a 30s dewatering operation.

[0077] In step S443, if the first fuzzy weight is greater than or equal to the preset weight, for example, the preset weight is 4 kg and the detected first fuzzy weight is 6 kg, which is greater than the preset weight, it indicates that the first fuzzy weight is heavy and a longer time can be used to spin dry the laundry, and thus the washing machine is made to perform a 60s dewatering operation.

[0078] It should be noted that the above-mentioned preset weight, first time and second time are exemplary and not limited, and those skilled in the art can determine the first fuzzy weight according to the actual detection result, and flexibly adjust and set the preset weight, first time and second time according to the actual operation of the washing machine, as long as the first time is less than the second time.

[0079] It should be further noted that in the above process, steps S442 and S443 have no sequence and are parallel, and are only related to the judgment result of whether the first fuzzy weight is less than the preset weight, and the corresponding steps can be performed according to different judgment results.

[0080] In step S432, the specific steps of making the washing machine perform the fuzzy weighing operation are: making the washing tub rotate, for example, alternating forward and reverse rotation, or forward rotation, or reverse rotation, so that the laundry in the washing tub is more evenly distributed, and then performing the weighing operation, so that the obtained second fuzzy weight is more accurate, for example, 2.4 kg, 2 kg, etc.

[0081] As shown in FIG. 4, the step S431 of "making the washing machine perform a preset-time dewatering operation" specifically includes: Figure 6 ​As shown, step S433, the step of "correcting the second fuzzy weight based on the first fuzzy weight to obtain the corrected weight of the second fuzzy weight" specifically includes:

[0082] S451. Calculate the second difference between the first fuzzy weight and the second fuzzy weight;

[0083] S452. Calculate the ratio between the second difference and the second fuzzy weight;

[0084] S453. Determine whether the ratio is greater than or equal to the preset ratio;

[0085] S454. Determine the correction coefficient based on the judgment result;

[0086] S455. Calculate the product of the correction coefficient and the second fuzzy weight, and use the product as the correction weight.

[0087] In step S451, the second difference Δm is the result of subtracting the detected second fuzzy weight m2 from the detected first fuzzy weight m1, that is, Δm = m1 - m2.

[0088] In step S452, the ratio ζ m ζ is calculated using the following formula. m =△m / m2=(m1-m2) / m2.

[0089] For example, if the first fuzzy weight m1 is 6 kg and the second fuzzy weight m2 is 2.4 kg, then ζ m = (6-2.4) / 2.4 = 1.5.

[0090] For example, if the first fuzzy weight m1 is 3kg and the second fuzzy weight m2 is 2kg, then ζ m = (3-2) / 2 = 0.5.

[0091] like Figure 7 As shown, step S454, "determining the correction coefficient based on the judgment result," specifically includes:

[0092] S461. If the ratio is greater than or equal to the preset ratio, the correction coefficient is determined as the first correction coefficient k1.

[0093] S462. If the ratio is less than the preset ratio, the correction coefficient is determined as the second correction coefficient k2.

[0094] Where k1 is greater than k2, and 0.5 < k1 ≤ 1, k2 ≤ 0.5.

[0095] In step S461, if the ratio is greater than or equal to the preset ratio, for example, the preset ratio is 1, and the calculated ratio is 1.5, which is greater than the preset ratio, it indicates that the material of the clothes is easy to remove water, and the water content of the clothes after the dehydration operation is less, and the difference with the real dry weight of the clothes is small. Therefore, the correction coefficient is determined as the first correction coefficient k1, for example, 0.6, 0.8, 1 or other coefficients, which can accurately correct the second fuzzy weight, so as to accurately determine the approximate dry weight of the clothes, which is closer to the real dry weight of the clothes, so that the corrected weight is closer to the real dry weight of the clothes.

[0096] In step S462, if the ratio is less than the preset ratio, for example, the preset ratio is 1, and the calculated ratio is 0.5, which is less than the preset ratio, it indicates that the material of the clothes is not easy to remove water, and the water content of the clothes after the dehydration operation is more, and the difference with the real dry weight of the clothes is large. Therefore, the correction coefficient is determined as the second correction coefficient k2, for example, 0.5, 0.3, 0.1 or other coefficients, which can accurately correct the second fuzzy weight, so that the corrected weight is closer to the real dry weight of the clothes.

[0097] It should be noted that in the above process, steps S461 and S462 have no sequence and are parallel, and are only related to the judgment result of whether the ratio is greater than or equal to the preset ratio, and the corresponding steps can be executed according to different judgment results.

[0098] In step S455, for example, the determined correction coefficient is the first correction coefficient k1, wherein k1 is 0.6, the second fuzzy weight m2 is 2.4 kg, and the calculated corrected weight m* is 0.6 x 2.4 kg = 1.44 kg.

[0099] For another example, the determined correction coefficient is the second correction coefficient k2, wherein k2 is 0.5, the second fuzzy weight m2 is 2 kg, and the calculated corrected weight m* is 0.5 x 2 kg = 1 kg.

[0100] In step S434, the preset weight range in which the corrected weight is located is determined according to the corrected weight, and the first water level is determined according to the preset weight range. Assuming that the washing machine includes three preset weight ranges, the three preset weight ranges correspond to different water levels, for example, the first preset weight range is 0kg-1kg, and the corresponding water level is the second water level; the second preset weight range is 1kg-2kg, and the corresponding water level is the third water level; and the third preset weight range is 2kg-3kg, and the corresponding water level is the fourth water level. Of course, the number of preset weight ranges included in the washing machine, the division manner of the preset weight ranges, and the corresponding water levels are not limited to the above-mentioned cases, and the weight range can also be divided into two ranges, four ranges, or other ranges, as long as each weight range corresponds to a different water level.

[0101] Further, if the corrected weight is 1.44kg, the weight of the clothes is in the second preset weight range, and accordingly, the corresponding first water level is the third water level; for example, the weight of the clothes is 1kg, the weight of the clothes is in the first preset weight range, and accordingly, the corresponding first water level is the second water level, that is, the preset weight range in which the corrected weight is located can be determined according to the corrected weight, and the water level can be determined according to the preset weight range in which the corrected weight is located.

[0102] In step S435, the first water level has been accurately determined according to the corrected weight, so that the first water level can meet the requirement of cleaning the clothes, and the water amount of the washing machine can be accurately controlled, so that the washing machine directly fills water to the first water level.

[0103] Alternatively, in an alternative embodiment, the step of "making the washing machine perform the water filling operation according to the first fuzzy weight and the water level frequency value" specifically includes:

[0104] It is determined whether the water level frequency value is less than the set frequency value; if the water level frequency value is less than the set frequency value, it is determined that the user not only puts the wet clothes into the washing tub, but also pours the water of the pre-washed clothes into the washing tub, and the washing machine is made to perform the segmented water filling operation; if the water level frequency value is greater than or equal to the set frequency value, it is determined that the user only puts the wet clothes into the washing tub, and does not pour the water of the pre-washed clothes into the washing tub, and the washing machine is made to perform the water filling operation according to the first fuzzy weight.

[0105] Of course, in actual application, the method of making the washing machine perform the water filling operation according to the first fuzzy weight and the water level frequency value is not limited to the above-mentioned two methods, and other methods can also be used to make the washing machine perform the water filling operation.

[0106] The following refers to Figure 8The control method of the present application is further described. Among them, Figure 8 is the flow of the control method of the present application Figure 2 .

[0107] As Figure 8 shown, the control method further comprises:

[0108] S511, in the case of detecting that the clothes are dry clothes, making the washing machine execute a fuzzy weighing operation to obtain a third fuzzy weight;

[0109] S512, detecting again the dryness of the clothes in the washing tub;

[0110] If it is detected again that the clothes are dry clothes, step S513 is executed;

[0111] If it is detected again that the clothes are wet clothes, return to step S200;

[0112] S513, determining a second water inlet level according to the third fuzzy weight;

[0113] S514, making the washing machine execute a water injection operation according to the second water inlet level.

[0114] In steps S511 and S512, in the case of detecting that the clothes are dry clothes, it is possible that the clothes are dry clothes or that the clothes are wet clothes, but the plurality of detection contacts are not in contact with the clothes, so that the wet clothes are not detected. In order to accurately judge the dryness of the clothes, the washing tub is rotated, for example, alternately rotated in forward and reverse directions, or rotated in forward direction or in reverse direction, so that the clothes in the washing tub are more evenly distributed, and then the dryness of the clothes is detected again by the detection circuit, avoiding the occurrence of misjudgment. Of course, the dryness of the clothes can be detected by the detection circuit at the same time of executing step S511.

[0115] Further, in the above process, after the clothes in the washing tub are more evenly distributed, the weighing operation is executed, so that the obtained third fuzzy weight is more accurate.

[0116] In step S513, if it is detected again that the clothes are dry clothes, it means that the clothes are definitely dry clothes, and the second water inlet level can be accurately determined according to the weight of the clothes. The specific determination method can refer to the description in step S434, which will not be described here.

[0117] In step S514, the second water inlet level has been accurately determined according to the weight of the clothes, so that the second water inlet level can meet the requirement of washing the clothes clean, and the water inlet amount of the washing machine can be accurately controlled, so that the washing machine directly injects water to the second water inlet level.

[0118] Further, if the clothes are detected to be wet clothes again, it indicates that the clothes are not evenly distributed in step S100, and the dryness of the clothes is not effectively detected. At this time, if the clothes are detected to be wet clothes, return to step S200, obtain F1, and take the third fuzzy weight as the third fuzzy weight, and execute according to the case of wet clothes, so as to avoid determining the water level according to the dry clothes when the clothes are actually wet, accurately control the water inlet amount of the washing machine, and avoid waste of water resources.

[0119] It should be noted that in the above process, steps S200 and S511 have no sequence and are parallel, and are only related to the detection result of the dryness of the clothes. According to different detection results, the corresponding steps can be executed. Steps S513 and S200 have no sequence and are parallel, and are only related to the detection result of the dryness of the clothes. According to different detection results, the corresponding steps can be executed.
