Description

Technical Field

[0001] This invention relates to the field of smart home technology, and specifically provides a control method for washing equipment, a computer-readable storage medium, and a washing equipment. Background Technology

[0002] With the improvement of people's living standards, washing equipment such as washing machines and washer-dryer combos have become very popular. Taking washing machines as an example, in actual operation, the washing machine may select a high water level or the user may select the water retention function, or other special situations may occur, causing the washing machine's water level sensor to be under high pressure, affecting the detection accuracy of the water level sensor and leading to inaccurate detection results.

[0003] To address the aforementioned issues, invention patent CN113445255A discloses "a control method, device, clothing processing equipment, and computer-readable storage medium," specifically including the following steps: after the water level reaches level 8, the water level frequency value A is measured. If the water level frequency value |A-2170|>50, the water level sensor is deemed faulty. If the water level detection device remains in an abnormal state, an alarm device is controlled to output a fault message indicating a timely repair to the user. However, this method only determines whether the water level sensor is faulty. Even if the water level sensor is not faulty, it will gradually age over time, reducing its detection accuracy. This can lead to either excessively high water levels, wasting water resources, or excessively low water levels, affecting the cleanliness of the clothes and impacting the user experience.

[0004] Therefore, there is a need in the art for a new control method, computer-readable storage medium, and washing device for washing equipment to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that existing washing equipment cannot accurately determine the water level.

[0006] In a first aspect, the present invention provides a control method for a washing device, the control method comprising the following steps: when the washing device performs a target operation, acquiring the actual empty tub water level frequency value of the washing device; determining whether the actual empty tub water level frequency value is greater than a preset water level frequency value; and, based on the determination result, selectively correcting the reference water level frequency value of the washing device or sending a prompt message.

[0007] In the preferred embodiment of the above control method, the step of "selectively correcting the reference water level frequency value of the washing equipment or sending a prompt message according to the judgment result" specifically includes: if the actual empty tub water level frequency value is greater than the preset water level frequency value, then count the number of times the washing equipment performs the target operation; determine whether the number of times has reached the preset number; and selectively correct the reference water level frequency value according to the judgment result.

[0008] In the preferred embodiment of the above control method, the reference water level frequency includes a reference empty bucket water level frequency value and multiple reference frequency values; the step of "selectively correcting the reference water level frequency value according to the judgment result" specifically includes: if the number of times reaches the preset number of times, then calculating the difference between the reference empty bucket water level frequency value and the actual empty bucket water level frequency value; determining whether the difference is greater than a preset difference; if the difference is greater than the preset difference, then correcting both the reference empty bucket water level frequency value and the multiple reference frequency values.

[0009] In the preferred embodiment of the above control method, the step of "correcting the reference empty tank water level frequency value and the plurality of reference frequency values" specifically includes: using the difference as a calibration value; correcting the reference empty tank water level frequency value and the plurality of reference frequency values ​​according to the calibration value to obtain the corrected water level frequency value.

[0010] In a preferred embodiment of the above control method, the control method further includes: if the number of times does not reach the preset number of times, then the reference water level frequency value is not corrected; and / or if the difference is less than or equal to the preset difference, then the reference water level frequency value is not corrected.

[0011] In the preferred embodiment of the above control method, the step of "selectively correcting the preset water level frequency value of the washing device or sending a prompt message according to the judgment result" further includes: if the actual empty tub water level frequency value is less than or equal to the preset water level frequency value, a prompt message is sent to remind the user that the water level sensor needs after-sales service.

[0012] In the preferred embodiment of the above control method, the washing equipment includes a water level sensor; the step of "obtaining the actual empty tub water level frequency value of the washing equipment" specifically includes: after the washing equipment has completed the last spin-drying operation, the actual empty tub water level frequency value is detected by the water level sensor.

[0013] In a preferred embodiment of the above control method, the control method further includes: after the washing equipment reaches a preset location, detecting the initial empty tub water level frequency value through the water level sensor; and using the initial empty tub water level frequency value as the reference empty tub water level frequency value.

[0014] In a second aspect, the present invention provides a computer-readable storage medium storing a plurality of program codes adapted to be loaded and run by a processor to perform the control method described in any of the preferred embodiments above.

[0015] In a third aspect, the present invention provides a washing device, the washing device comprising: a processor; a memory for storing a plurality of program codes; the program codes being adapted to be loaded and run by the processor to perform the control method described in any of the preferred technical solutions above.

[0016] In a preferred embodiment of the control method of the present invention, when the washing machine is performing the target operation, the actual empty drum water level frequency value of the washing machine is obtained; it is determined whether the actual empty drum water level frequency value is greater than the preset water level frequency value; based on the determination result, the reference water level frequency value of the washing machine is selectively corrected or a prompt message is sent.

[0017] Compared to existing technologies that only indicate a malfunction in the water level detection device, this invention, when the washing machine is performing a target operation—that is, when the water level sensor is constantly under high pressure and prone to damage or malfunction—can promptly acquire the actual empty drum water level frequency value of the washing machine. Based on whether the actual empty drum water level frequency value is greater than a preset water level frequency value, it can promptly and accurately determine whether the water level sensor is malfunctioning, whether a fault warning is needed, and whether the washing machine's reference water level frequency value needs correction. Based on this, it selectively corrects the washing machine's reference water level frequency value or sends a warning message, ensuring the accuracy of the detected actual water level frequency value. Accurately determining the water level based on the detected actual water level frequency value not only ensures clothes are washed clean but also avoids water waste. Furthermore, it allows users to be aware of the issue and contact after-sales service promptly, thereby improving the user experience.

[0018] Furthermore, if the actual empty tub water level frequency value is greater than the preset water level frequency value, it indicates that the water level sensor's detection result is relatively accurate and within the normal deviation range, meaning the water level sensor is not faulty and can be used normally. However, as the usage time increases, the detection accuracy of the water level sensor will gradually decrease. Therefore, by counting the number of times the washing machine performs the target operation and judging whether the count reaches the preset number, it is possible to accurately determine whether the detection accuracy of the water level sensor has significantly decreased, whether the detection result of the water level sensor has a large deviation, whether the detection result of the water level sensor matches the washing machine's reference water level frequency value, and whether the reference water level frequency value needs to be corrected. Based on this, the reference water level frequency value is selectively corrected so that the water level can be accurately determined based on the corrected water level frequency value, further ensuring the accuracy of the determined water level.

[0019] Furthermore, if the number of times reaches the preset number, it means that the washing machine has performed the target operation multiple times, causing the water level sensor to be under high pressure multiple times. This may reduce the detection accuracy of the water level sensor, or even affect the accuracy of water level determination. In this case, the difference between the actual empty tub water level frequency value and the reference empty tub water level frequency value is calculated. When the difference is greater than the preset difference, it means that the detection result of the water level sensor deviates significantly from the reference water level frequency value corresponding to the target water level. The water level cannot be accurately determined based on the detection result of the water level sensor. Therefore, the reference water level frequency value needs to be corrected so that the water level can be accurately determined based on the corrected water level frequency value.

[0020] Furthermore, if the actual empty bucket water level frequency value is less than or equal to the preset water level frequency value, it indicates that the water level sensor's detection result is too low and has deviated from the normal deviation range. The water level sensor has malfunctioned or is abnormal and cannot eliminate the impact through self-calibration. In this case, a prompt message is sent to notify the user of the water level sensor malfunction or abnormality, so that the user can be aware of it and contact after-sales service in a timely manner. This avoids continued use when the water level sensor is malfunctioning or abnormal, and further ensures the accuracy of the detected actual water level frequency value. Attached Figure Description

[0027] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although this application is described in conjunction with a washing machine, the technical solution of the present invention is not limited thereto, and this control method can obviously also be applied to other washing equipment such as washer-dryer combos and steam washing equipment; such changes do not depart from the principles and scope of the present invention. The washing machine can be a top-loading washing machine or a front-loading washing machine.

[0028] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] Based on the technical problems mentioned in the background art, this invention provides a control method for a washing machine. The method aims to promptly acquire the actual empty drum water level frequency value of the washing machine when the washing machine is performing a target operation, specifically when the water level sensor is constantly under high pressure and prone to damage or malfunction. Based on whether the actual empty drum water level frequency value is greater than a preset water level frequency value, the method can promptly and accurately determine whether the water level sensor is malfunctioning, whether a fault warning is needed, and whether the washing machine's reference water level frequency value needs correction. Based on this, the method selectively corrects the washing machine's reference water level frequency value or sends a warning message, ensuring the accuracy of the detected actual water level frequency value. Accurately determining the water level based on the detected actual water level frequency value not only ensures that clothes are washed clean but also avoids water waste. Furthermore, it allows users to be aware of the issue and contact after-sales service promptly, thereby improving the user experience.

[0030] First see Figure 1 The control method of the present invention will be described below. Figure 1 This is a flowchart of the control method of the present invention.

[0031] like Figure 1 As shown, the control method of the present invention includes the following steps:

[0032] S100. When the washing machine is performing the target operation, obtain the actual empty drum water level frequency value of the washing machine.

[0033] S200: Determine whether the actual empty bucket water level frequency value is greater than the preset water level frequency value;

[0034] S300: Based on the judgment result, selectively correct the reference water level frequency value of the washing machine or send a prompt message.

[0035] Preferably, the washing machine is equipped with a water level sensor, which is used to detect the water level frequency value of the washing machine.

[0036] The target operation could be that the washing or rinsing water level of the washing machine is higher than a preset water level. For example, the preset water level could be level eight, nine, or ten, or other water levels that would cause the water level sensor to be under high pressure. Alternatively, the target operation could be that when the washing machine performs a water retention function, the washing water remains in the washing machine for an extended period, causing the water level sensor to remain under high pressure. Of course, the target operation could also be other operations that cause the water level sensor to be under high pressure, which will not be listed here.

[0037] In step S100, when the washing machine performs the above-mentioned target operation, after the washing machine has completed the last spin-drying operation and the washing water has been drained, the water level sensor can accurately detect the actual empty drum water level frequency value.

[0038] The following reference Figures 2 to 4 The present invention describes a control method for selectively correcting a reference water level frequency value or sending a prompt message. Wherein, Figure 2 This is a flowchart of the control method of selectively correcting the reference water level frequency value or sending a prompt message according to the present invention; Figure 3 This is a flowchart of the control method for selectively correcting the reference water level frequency value according to the present invention; Figure 4 This is a flowchart of the control method for correcting the reference water level frequency value according to the present invention.

[0039] like Figure 2 As shown, step S300, "selectively correcting the reference water level frequency value of the washing machine or sending a prompt message based on the judgment result," specifically includes:

[0040] S311. If the actual empty bucket water level frequency value is less than or equal to the preset water level frequency value, a prompt message will be sent to remind the user that the water level sensor needs after-sales service.

[0041] S312. If the actual empty tub water level frequency value is greater than the preset water level frequency value, then count the number of times the washing machine performs the target operation.

[0042] S313. Determine whether the preset number of attempts has been reached;

[0043] S314. Based on the judgment result, selectively correct the reference water level frequency value.

[0044] In step S311, if the actual empty bucket water level frequency value is less than or equal to the preset water level frequency value, for example, the preset water level frequency value is 41900Hz, and the detected actual empty bucket water level frequency value is 41880Hz, which is less than the preset water level frequency value, it indicates that the detection result of the water level sensor is too low and has deviated from the normal deviation range. The water level sensor has malfunctioned or is abnormal and cannot eliminate the influence through self-calibration. In this case, a prompt message is sent to inform the user that the water level sensor has malfunctioned or is abnormal, so that the user can be aware of it and contact after-sales service in time for processing. This avoids continued use when the water level sensor has malfunctioned or is abnormal, and further ensures the accuracy of the detected actual water level frequency value.

[0045] Preferably, the washing machine can be controlled to send prompt messages to user devices such as mobile phones, tablets, and smart bracelets; or, the washing machine's voice module can be controlled to send prompt messages by voice; or, a smart speaker or other voice device connected to the washing machine can be controlled to send prompt messages by voice; or, the washing machine can be controlled to display the prompt messages on its display component, so that the display component sends the prompt messages by voice or text.

[0046] In step S312, if the actual empty tub water level frequency value is greater than the preset water level frequency value, for example, the preset water level frequency value is 41900Hz and the detected actual empty tub water level frequency value is 42100Hz, which is greater than the preset water level frequency value, it means that the detection result of the water level sensor is relatively accurate and within the normal deviation range. The water level sensor is not faulty and can be used normally. However, as the usage time increases, the detection accuracy of the water level sensor will gradually decrease. Therefore, the number of times the washing machine performs the target operation is counted so as to further determine whether the reference water level frequency value needs to be corrected based on the count, thereby ensuring the accuracy of the determined water level.

[0047] The reference water level frequency values ​​include the reference empty tub water level frequency value, as well as other reference frequency values ​​such as reference one water level frequency value, reference two water level frequency value, and reference three water level frequency value. The number of reference water level frequency values ​​is determined according to the water level of the washing machine, and each water level corresponds to a reference water level frequency value.

[0048] Preferably, after the washing machine reaches the preset location, that is, before the washing machine starts running, the water level sensor detects the initial water level frequency value as the reference empty drum water level frequency value. This initial water level frequency value is used as the reference empty drum water level frequency value. Based on this initial water level frequency value and a preset frequency interval, other initial water level frequency values ​​are sequentially determined, such as initial first water level frequency value, initial second water level frequency value, and initial third water level frequency value. These determined initial first, second, and third water level frequency values ​​are then used as the current reference first, reference second, and reference third water level frequency values, respectively. For example, if the initial water level frequency value of the empty drum is 42200Hz and the preset frequency interval is 1000Hz, then the initial first water level frequency value (i.e., reference first water level frequency value) is 41200Hz, the initial second water level frequency value (i.e., reference second water level frequency value) is 40200Hz, and the initial third water level frequency value (i.e., reference third water level frequency value) is 39200Hz, and so on. If the reference water level frequency value has been corrected, the corrected reference water level frequency value will be used as the latest reference water level frequency value. See below for details on the correction method.

[0049] The pre-defined locations include, but are not limited to, users' homes, dormitories, hotels, nursing homes, and other places where washing machines are used.

[0050] It should be noted that the preset water level frequency value, preset frequency interval, reference water level frequency value and actual empty drum water level frequency value listed above are merely illustrative and not restrictive. Those skilled in the art can flexibly adjust and set the preset water level frequency value, preset frequency interval and reference water level frequency value according to the actual situation of the washing machine, and determine the actual empty drum water level frequency value based on the actual test results.

[0051] It should also be noted that in the above process, steps S311 and S312 are not sequential but parallel, and are only related to the judgment result of whether the actual empty bucket water level frequency value is greater than the preset water level frequency value. The corresponding steps can be executed according to different judgment results.

[0052] like Figure 3 As shown, step S314, "selectively correcting the reference water level frequency value based on the judgment result," specifically includes:

[0053] If the preset number of attempts is reached, then proceed to step S321;

[0054] If the preset number of attempts is not reached, proceed to step S324;

[0055] S321. Calculate the difference between the reference empty tank water level frequency value and the actual empty tank water level frequency value;

[0056] S322. Determine whether the difference is greater than the preset difference; if yes, proceed to step S323; if no, proceed to step S324.

[0057] S323. Correct the reference empty tank water level frequency value and multiple reference frequency values;

[0058] S324. No correction is made to the reference water level frequency value.

[0059] In step S321, if the number of times reaches the preset number, for example, the preset number is 3 times and the number of times counted is 3, reaching the preset number means that the washing machine has performed the target operation 3 times, causing the water level sensor to be under high pressure 3 times. This may reduce the detection accuracy of the water level sensor, or even affect the accuracy of the water level determination. Then, the difference between the actual empty tub water level frequency value and the reference empty tub water level frequency value is calculated. Based on the calculated difference, it is further determined whether the reference water level frequency value should be corrected, thus further ensuring the accuracy of the determined water level.

[0060] Furthermore, the reference empty bucket water level frequency value F 01 Frequency value F of actual empty bucket water level 02 Compare and determine F based on the comparison results. max With F min The difference ΔF = F max -F min Therefore, the difference is either positive or zero.

[0061] For example, the reference empty bucket water level frequency value F 01 The actual frequency value of the empty bucket water level is 42200Hz. 02 If the Hz is 42220Hz, then ΔF = 42220Hz - 42200Hz = 20Hz.

[0062] For example, the reference empty bucket water level frequency value F 01 The actual frequency value of the empty bucket water level is 42200Hz. 02 If the Hz is 42000Hz, then ΔF = 42200Hz - 42000Hz = 200Hz.

[0063] In step S323, if the difference is greater than the preset difference, for example, if the preset difference is 50Hz and the calculated difference ΔF is 200Hz, which is greater than the preset difference, it means that the detection result of the water level sensor deviates significantly from the corresponding reference water level frequency value. This indicates that the detection accuracy of the water level sensor has decreased, and the water level cannot be accurately determined based on the detection result of the water level sensor. Therefore, it is necessary to correct the reference water level frequency value so that the corrected reference water level frequency value can match the detection result of the water level sensor, thereby enabling the water level to be accurately determined based on the detection result of the water level sensor.

[0064] Preferably, such as Figure 4 As shown, step S323, the step of "correcting the reference water level frequency value" specifically includes:

[0065] S331. Use the difference as the calibration value;

[0066] S332. Correct the reference empty tank water level frequency value and multiple reference frequency values ​​according to the calibration value to obtain the corrected water level frequency value.

[0067] For example, the calculated difference ΔF is 200Hz, and the reference empty bucket water level frequency value F 01 The frequency value F is 42200Hz, the reference water level frequency value. 11 The frequency value F of the reference water level is 41200Hz. 21 The frequency value F is 40200Hz, the reference three-level water level. 31 It is 39200Hz.

[0068] If F 01 >F 02 Then calculate F respectively 11 F 21 F 31 The difference between the value of F and the value of ΔF is used to obtain the corrected water level frequency value. For example, the corrected empty bucket water level frequency value F. 03 The corrected water level frequency value F is 42000Hz. 12 The corrected frequency value F of the two water levels is 41000Hz. 22 The corrected three-water-level frequency value F is 40000Hz. 32 The corrected water level frequency value is 39000Hz. The corrected water level frequency value is used to replace the reference water level frequency value as the latest reference water level frequency value.

[0069] If F 01 Less than F 02 Then calculate the sum of F1, F2, F3 and ΔF respectively. For example, the corrected empty bucket water level frequency value F 03 The corrected water level frequency value F is 42400Hz. 12 The corrected frequency value F of the two water levels is 41400Hz. 22 The corrected three-water-level frequency value F is 40400Hz. 32 The corrected water level frequency value is 39400Hz. The corrected water level frequency value is used to replace the reference water level frequency value as the latest reference water level frequency value.

[0070] Alternatively, in an alternative implementation, the detection results of the water level sensor can be corrected. For example, if the calculated difference ΔF is 200Hz, and F... 01 >F 02Then, the sum of the detection result of the water level sensor and ΔF is calculated to obtain the correction value of the detection result of the water level sensor. For example, the actual water level frequency value F detected by the water level sensor. 13 If the frequency is 41000Hz, then the corrected detection result is 41200Hz, which is the same as the reference water level frequency value F. 11 This allows for accurate determination of the water level.

[0071] If F 01 Less than F 02 Then, the difference between the detection result of the water level sensor and ΔF is calculated to obtain the correction value of the detection result of the water level sensor. For example, the actual water level frequency value F detected by the water level sensor. 13 If the frequency is 41400Hz, then the corrected detection result is 41200Hz, which is the same as the reference water level frequency value F. 11 This allows for accurate determination of the water level.

[0072] In step S324, if the difference is less than or equal to the preset difference, for example, if the preset difference is 50Hz and the calculated difference ΔF is 20Hz, which is less than the preset difference, it means that the deviation between the detection result of the water level sensor and the corresponding reference water level frequency value is small, indicating that the detection accuracy of the water level sensor has not been significantly reduced and the water level can be accurately determined. Therefore, there is no need to correct the reference water level frequency value.

[0073] Furthermore, if the number of times is less than the preset number, for example, if the preset number is 3 times but the number of times counted is 1, it means that the washing machine only performed the target operation once, and the water level sensor was under high pressure only once. This has little impact on the detection accuracy of the water level sensor. The water level can be accurately determined based on the detection results of the water level sensor, so there is no need to correct the reference water level frequency value.

[0074] It should be noted that the preset number of times, the statistically calculated number of times, the preset difference, the calculated difference, the reference water level frequency value, and the corrected water level frequency value listed above are merely illustrative and not restrictive. Those skilled in the art can flexibly adjust and set the preset number of times, the preset difference, and the reference water level frequency value according to the actual situation of the washing machine, determine the statistically calculated number of times based on the actual operating conditions, and calculate the difference between the actual empty tub water level frequency value and the reference empty tub water level frequency value, as well as the corrected water level frequency value, based on the actual detected empty tub water level frequency value.

[0075] It should also be noted that in the above process, steps S321 and S324 are not sequential but parallel, and are only related to the judgment result of whether the counted number reaches the preset number. The corresponding steps are executed according to different judgment results. Similarly, steps S323 and S324 are not sequential but parallel, and are only related to the judgment result of whether the calculated difference is greater than the preset difference. The corresponding steps are executed according to different judgment results.
