Abstract

This application relates to a washing machine control method, device, and washing machine. Whenever the washing machine starts and executes the current washing task, it acquires the current turbidity parameter of the wastewater discharged from the drain outlet. This parameter is then combined with historical turbidity parameters of the wastewater discharged from the drain outlet during each washing task from the first start to the last time the washing machine was turned on until the current washing task began, to analyze whether the washing machine meets the drum cleaning conditions. When the washing machine meets the drum cleaning conditions, a drum cleaning reminder message is pushed to the user so that the user can clean the washing machine's drum promptly. This solution links drum cleaning with the turbidity of the wastewater discharged from the drain outlet, automatically analyzes whether the washing machine meets the drum cleaning conditions, and pushes a drum cleaning reminder message to the user when the conditions are met. This eliminates the need for the user to manually determine whether to activate drum cleaning, thus solving the problem of drum cleaning being frequently activated or not activated even when the machine is severely dirty.

Description

Technical Field

[0001] This application relates to the field of washing machine technology, and in particular to a washing machine control method, device, and washing machine. Background Technology

[0002] With the rapid development of science and technology and the continuous improvement of people's living standards, washing machines have gradually become a necessity of life, bringing great convenience to people's daily lives. However, during the use of a washing machine, the drum is easily contaminated and breeds bacteria, ultimately endangering the user's health.

[0003] To prevent bacterial growth, washing machines generally have a drum cleaning function. However, the drum cleaning function requires users to manually turn it on based on experience, which can easily lead to frequent openings or failure to turn it on when the drum is severely dirty. Summary of the Invention

[0004] Therefore, it is necessary to provide a washing machine control method, device, and washing machine to solve the problem that the drum is easily turned on frequently when clean or remains closed even when severely dirty.

[0006] The aforementioned washing machine control method acquires the current turbidity parameter of the wastewater discharged from the drain outlet each time the washing machine starts executing the current washing task. This parameter is then combined with historical turbidity parameters of the wastewater discharged from the drain outlet from the first start of the washing machine or the last time a drum cleaning task was executed, up to and including the current washing task, to analyze whether the washing machine meets the drum cleaning conditions. When the washing machine meets the drum cleaning conditions, a drum cleaning reminder message is pushed to the user so that the user can perform drum cleaning promptly. This solution links drum cleaning to the turbidity of the wastewater discharged from the drain outlet, automatically analyzes whether the washing machine meets the drum cleaning conditions, and pushes a drum cleaning reminder message to the user when the conditions are met. This eliminates the need for the user to manually determine whether to activate drum cleaning, thus solving the problem of drum cleaning being frequently activated or not activated even when the machine is severely dirty.

[0013] In one embodiment, determining the expected value for drum cleaning based on the current dirt level coefficient and the drainage rate includes: determining the expected value for drum cleaning based on the current dirt level coefficient, the drainage rate, and a preset drum cleaning expectation model.

[0014] In one embodiment, the preset drum cleaning expectation model includes: E = D * 1 / V, where E is the drum cleaning expectation value, D is the current dirt level coefficient, V is the drainage rate, and * indicates multiplication.

[0015] In one embodiment, determining whether the washing machine meets the drum cleaning conditions based on the drum cleaning expectation value includes: if the drum cleaning expectation value is greater than or equal to a preset expectation threshold, determining that the washing machine meets the drum cleaning conditions.

[0016] A washing machine control device includes: a turbidity acquisition module for acquiring a current turbidity parameter; the current turbidity parameter being the turbidity parameter of wastewater discharged from the drain outlet of the washing machine when the washing machine performs the current washing task; a cleaning detection module for determining whether the washing machine meets the drum cleaning conditions based on the current turbidity parameter and historical turbidity parameters; the historical turbidity parameter being the turbidity parameter of wastewater discharged from the drain outlet during each washing task from the first start of the washing machine or after the last drum cleaning task to before the current washing task; and a cleaning reminder module for pushing a drum cleaning reminder message if the washing machine meets the drum cleaning conditions.

[0031] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0032] The washing machine control method provided in this application is applied to... Figure 1 In the scenario shown, the washing machine includes a cleaning drum 112, a controller (not shown), a turbidity detector 116, a flow rate detector 119, and a housing 118. The cleaning drum 112 is located inside the housing 118 and is used to hold the clothes to be washed and the washing water. The housing 118 has a drain outlet 114, which is connected to the cleaning drum 112 via a pipe. The turbidity detector 116 and the flow rate detector 119 are respectively located at the drain outlet 114 and are respectively connected to the controller. During the washing process, the wastewater generated can be discharged through the drain outlet 114. The turbidity detector 116 is used to collect the turbidity data of the wastewater discharged from the drain outlet 114, while the flow rate detector 119 is used to detect the drainage rate of the wastewater discharged from the drain outlet 114. The controller receives the turbidity data collected and transmitted by the turbidity detector 116 and the drainage rate collected and transmitted by the flow rate detector 119, and performs further analysis based on the turbidity data to determine the final turbidity parameters. Ultimately, the controller controls the washing machine based on the current turbidity parameters of the current washing task and the historical turbidity parameters from the first start of the washing machine or the period before the last drum cleaning task. Furthermore, in one embodiment, the controller can also combine the turbidity parameters, historical turbidity parameters, and historical turbidity parameters to achieve washing machine control.

[0033] Please see Figure 2 A washing machine control method includes steps 202, 204 and 206.

[0034] Step 202: Obtain the current turbidity parameter.

[0035] Specifically, the current turbidity parameter refers to the turbidity of the wastewater discharged from the washing machine's drain outlet during the current washing cycle. In actual washing, the degree of soiling of the clothes being washed in the washing machine directly affects the degree of soiling in the drum; the dirtier the clothes, the higher the turbidity of the soaking or washing water, and consequently, the more severe the contamination of the drum. Therefore, this embodiment uses the turbidity parameter of the wastewater discharged from the washing machine's drain outlet to control the washing machine.

[0036] It is understood that there is no single way to obtain turbidity parameters. In one embodiment, a turbidity detector is installed at the drain outlet to collect data on the discharged wastewater and send the data to a controller connected to it (either via wired or wireless connection). The controller then determines the current turbidity parameter.

[0037] In one embodiment, since the washing machine drains water for a certain period of time due to the large amount of water in the drum, the turbidity detector can collect turbidity data corresponding to multiple different drainage times during the washing machine's drainage process. After the controller acquires each turbidity data, it performs analysis and processing (such as averaging) to obtain the final current turbidity parameter, thereby ensuring the accuracy of the current turbidity parameter.

[0038] Furthermore, in other embodiments, two or more turbidity detectors may be set at the drain outlet. During the drainage process, each turbidity detector collects turbidity data and sends it to the controller. The controller combines the turbidity data collected by each turbidity detector for analysis and processing (such as averaging) to finally obtain the current turbidity parameter, thereby ensuring the accuracy of the current turbidity parameter.

[0039] It should be noted that, in another embodiment, a turbidity detector can be set up to collect turbidity data once during the washing machine's drainage process, which is then used as the current turbidity parameter, thereby improving the detection efficiency of the current turbidity parameter.

[0040] Step 204: Determine whether the washing machine meets the drum cleaning conditions based on the current turbidity parameters and historical turbidity parameters.

[0041] Specifically, the historical turbidity parameter refers to the turbidity parameter of the wastewater discharged from the drain outlet during each washing task, after the washing machine is first turned on or after the last drum cleaning task and before the current washing task.

[0042] Drum cleaning conditions refer to the conditions that must be met to clean the drum of a washing machine. If the washing machine has not performed a drum cleaning task before, the actual analysis process needs to combine the current turbidity parameters with the turbidity parameters obtained by the controller during each cleaning task performed from the first start to the current cleaning task to determine whether the washing machine currently meets the drum cleaning conditions.

[0043] If the washing machine has already performed a drum cleaning task, the controller will re-calculate the turbidity parameters after the drum cleaning task is completed. It will analyze the turbidity parameters obtained by the controller during each cleaning task from the time the outer drum cleaning task was performed until the current cleaning task, as well as the current turbidity parameters, to determine whether the washing machine meets the drum cleaning conditions.

[0044] Step 206: If the washing machine meets the drum cleaning requirements, send a drum cleaning reminder message.

[0045] Specifically, after the controller detects that the washing machine meets the drum cleaning conditions, it will generate a drum cleaning reminder and push it to the user so that the user can be notified in time and start the drum cleaning task when the washing machine is idle.

[0046] It is understood that, in one embodiment, the drum cleaning task of the washing machine can also be started automatically. After the controller determines that the drum cleaning conditions are met by combining the current turbidity parameters and historical turbidity parameters, in addition to pushing drum cleaning reminder information to the user, the drum cleaning operation can also be started when the washing machine detects that it has completed the current washing task and is in an idle state.

[0047] It should be noted that the method of pushing drum cleaning reminder information is not unique. In one embodiment, the washing machine may be equipped with an information prompting device, the controller may push the drum cleaning reminder information to the information prompting device, and then the information prompting device may output a prompt signal to inform the user.

[0048] The specific type of information notification device is not unique. In a more detailed embodiment, the information notification device can be any one of a display screen, an audible alarm, or a visual alarm. The specific type of information notification device used is not limited.

[0049] Furthermore, in one embodiment, the drum cleaning reminder information can also be pushed to the user terminal to inform the user. In this embodiment, the controller is communicatively connected to the user terminal (which may be a mobile phone or wearable device, etc.). When the controller detects that the washing machine meets the drum cleaning conditions, it pushes the drum cleaning reminder information to the user terminal, which the user can view.

[0050] The aforementioned washing machine control method acquires the current turbidity parameter of the wastewater discharged from the drain outlet each time the washing machine starts executing the current washing task. This parameter is then combined with historical turbidity parameters of the wastewater discharged from the drain outlet from the first start of the washing machine or the last time a drum cleaning task was executed, up to and including the current washing task, to analyze whether the washing machine meets the drum cleaning conditions. When the washing machine meets the drum cleaning conditions, a drum cleaning reminder message is pushed to the user so that the user can perform drum cleaning promptly. This solution links drum cleaning to the turbidity of the wastewater discharged from the drain outlet, automatically analyzes whether the washing machine meets the drum cleaning conditions, and pushes a drum cleaning reminder message to the user when the conditions are met. This eliminates the need for the user to manually determine whether to activate drum cleaning, thus solving the problem of drum cleaning being frequently activated or not activated even when the machine is severely dirty.

[0051] In one embodiment, the turbidity parameter of the wastewater discharged from the drain outlet is the turbidity parameter of the soaking wastewater discharged from the drain outlet after the soaking stage is completed.

[0052] Specifically, clothing washing generally consists of soaking, washing, rinsing, and spin-drying stages. The soaking stage refers to the time period during which the washing machine soaks the clothes during the washing task; the soaking wastewater is the wastewater discharged after the clothes in the washing drum have been soaked. In this embodiment, the controller specifically analyzes the turbidity data collected by the turbidity detector from the wastewater discharged from the drain after the soaking stage to obtain the corresponding turbidity parameters. That is, in the current washing task and in previous washing tasks, the controller analyzes the turbidity data of the soaking wastewater to obtain the turbidity parameters, and performs corresponding control operations based on the turbidity parameters of the soaking wastewater in each washing task.

[0053] In this embodiment, the turbidity parameter is obtained by analyzing the soaking wastewater discharged during the soaking stage when each cleaning task is performed. This allows the turbidity parameter to more accurately characterize the degree of dirtiness of the cleaning cylinder and improve the reliability of cylinder cleaning detection.

[0054] It is understood that in other embodiments, since some washing tasks do not have a soaking stage (e.g., washing tasks for wool or silk garments), the turbidity parameter of the wastewater discharged from the drain outlet can also be: the turbidity parameter of the washing wastewater discharged from the drain outlet after the washing stage is completed. The washing stage is the time period for cleaning and rinsing the garments; the washing wastewater is the wastewater discharged after cleaning and rinsing the garments. The solution in this embodiment, by obtaining the turbidity parameter of the washing wastewater discharged after the washing stage is completed, can also achieve the detection operation of drum cleaning.

[0055] Please see Figure 3In one embodiment, step 204 includes steps 302 and 304.

[0056] Step 302: Determine the average turbidity value based on the current turbidity parameter and the historical turbidity parameter.

[0057] Step 304: Determine whether the washing machine meets the drum cleaning conditions based on the average turbidity value.

[0058] Specifically, in this embodiment, after the controller obtains the current turbidity parameter corresponding to the current cleaning task and the historical turbidity parameter obtained under the historical cleaning task of the current drum cleaning cycle, it calculates the average value of each turbidity parameter to obtain the average turbidity value, and finally uses the average turbidity value to analyze whether the washing machine meets the drum cleaning conditions.

[0059] Understandably, in one embodiment, if the cylinder cleaning conditions are met and the cylinder cleaning operation is completed, the controller will clear the historical turbidity parameters in the cylinder cleaning detection program and restart the next cylinder cleaning cycle. Conversely, if the controller analyzes the current turbidity parameters and historical turbidity parameters and determines that the cylinder cleaning conditions are not met, it will update and store the current turbidity parameters in the historical turbidity parameters and continue to execute the next cleaning task according to user needs. During each cleaning task, the controller will obtain the current turbidity parameters and calculate them against the historical turbidity parameters to obtain the average turbidity value. The controller will then analyze whether the cylinder cleaning conditions are met based on the average turbidity value.

[0060] Please see Figure 4 In one embodiment, step 304 includes steps 402 and 404.

[0061] Step 402: Determine the current dirtiness coefficient based on the average turbidity value and the preset correspondence between the average turbidity value and the dirtiness coefficient.

[0062] Step 404: Determine whether the washing machine meets the drum cleaning conditions based on the current dirt level coefficient.

[0063] Specifically, in this embodiment, the dirt level coefficient is used to characterize the dirt level of the washing machine's drum. The controller has a pre-stored correspondence between the average turbidity value and the dirt level coefficient. After the controller analyzes the current turbidity parameter and historical turbidity parameters to obtain the average turbidity value, it substitutes this average turbidity value into the pre-stored correspondence between the average turbidity value and the dirt level coefficient for matching, thus obtaining the current dirt level coefficient. Finally, based on the current dirt level coefficient, the controller further determines whether the washing machine meets the drum cleaning conditions.

[0064] The method for obtaining the preset correspondence between the average turbidity and the degree of dirtiness coefficient is not unique. In a more detailed embodiment, it can be obtained by testing the same model of washing machine in an experimental environment and storing it in the controller of the washing machine.

[0065] It should be noted that the correspondence between the average turbidity and the degree of dirtiness coefficient is not stored in the controller in a unique way. In one embodiment, it can be stored in the form of a graph, table, etc., and there is no specific limitation.

[0066] In one embodiment, different dirtiness coefficients can be set for different turbidity average ranges. Turbidity averages within the same turbidity average range have the same dirtiness coefficient, while turbidity averages within different turbidity average ranges will have different dirtiness coefficients. In a more detailed embodiment, four dirtiness coefficients are used as an example for explanation, as shown in the table below:

[0067]

[0068] in, D1 <D2<D3<D4, These represent different turbidity averages. D1, D2, D3, and D4 represent the degree of contamination coefficients. If the current turbidity average is at... If the current turbidity average value is within a certain range, then the corresponding current level of dirtiness is D1; ​​if the current average turbidity value is within a certain range... If the current turbidity average value is within a certain range, then the corresponding current level of dirtiness is D2; if the current average turbidity value is within a certain range... If the current turbidity average value is within a certain range, then the corresponding current level of dirtiness is D3; if the current average turbidity value is within a certain range... If the current level of dirt is within a certain range, then the corresponding current level of dirt is D4.

[0069] It is understood that in another embodiment, each average turbidity value may correspond to a degree of dirtiness coefficient, with the higher the average turbidity value, the higher the degree of dirtiness coefficient. The correspondence between the average turbidity value and the degree of dirtiness coefficient is not unique; the specific correspondence can be set according to actual needs and is not limited here.

[0070] Please see Figure 5 In one embodiment, step 404 includes step 502.

[0071] Step 502: If the current dirt level coefficient is greater than or equal to the preset coefficient threshold, determine that the washing machine meets the drum cleaning conditions.

[0072] Specifically, the controller has a preset coefficient threshold. After the controller analyzes and obtains the current dirt level coefficient, it will compare and analyze it with the preset coefficient. When the current dirt level coefficient is greater than or equal to the preset coefficient threshold, the washing machine is considered to meet the drum cleaning conditions.

[0073] The solution in this embodiment directly determines that the washing machine meets the drum cleaning conditions after detecting that the current dirt level coefficient is greater than or equal to the preset coefficient threshold, and then pushes a drum cleaning reminder message, which has the advantage of fast detection speed.

[0074] It should be noted that the preset coefficient threshold is not unique; it varies depending on the correspondence between the average turbidity and the degree of soiling coefficient. In a more detailed embodiment, the degree of soiling coefficients include D1, D2, D3, and D4, and the preset coefficient threshold can be set to D3.

[0075] In another embodiment, if the current dirt level coefficient is less than a preset coefficient threshold, it is determined that the washing machine does not meet the drum cleaning conditions. At this time, the current turbidity parameter will be recorded, and the cleaning task will continue to be performed according to the user's needs.

[0076] Please see Figure 6 In one embodiment, step 404 includes steps 602 and 604.

[0077] Step 602: If the current dirt level coefficient is greater than or equal to the preset coefficient threshold, obtain the drainage rate of the last drainage when the washing machine performs the current washing task.

[0078] Step 604: Determine whether the washing machine meets the drum cleaning conditions based on the current dirt level coefficient and drainage rate.

[0079] Specifically, during the washing cycle, once the machine enters the draining stage, the drain outlet filters out lint, yarn, fine sand, and other substances, which are also components of the contaminants inside the washing machine drum. Smaller particles flow out through the drain pipe, but larger particles are filtered and remain on the filter screen. When these contaminants accumulate to a certain extent, they affect the washing machine's drainage. In other words, the amount of water drained can, to some extent, reflect the level of dirtiness in the washing machine's drum.

[0080] Therefore, in this embodiment, when the current dirt level coefficient is detected to be greater than or equal to a preset threshold, the controller further needs to obtain the drainage rate of the last drainage during the current washing cycle. Finally, by combining the drainage rate and the current dirt level coefficient, the system detects whether the drum cleaning condition is met. This solution, by combining the current dirt level coefficient and drainage rate to determine whether the drum cleaning condition is met when the current dirt level coefficient is detected to be greater than or equal to the preset threshold, improves the accuracy of drum cleaning detection.

[0081] It is understood that the method of obtaining the drainage rate is not unique. In one embodiment, the washing machine's drain outlet is equipped with a flow rate detector, which can collect the water flow rate during the washing machine's drainage process. Furthermore, the flow rate corresponding to the last drainage operation of the washing task can simply be used as the drainage rate.

[0082] Please see Figure 7 In one embodiment, step 604 includes steps 702 and 704.

[0083] Step 702: Determine the expected value of cylinder cleaning based on the current dirt level coefficient and drainage rate.

[0084] Step 704: Determine whether the washing machine meets the drum cleaning conditions based on the drum cleaning expectation value.

[0085] Specifically, there is no single way to determine whether the drum cleaning conditions are met based on the current dirt level coefficient and drainage rate. In this embodiment, the solution requires analysis and calculation based on the current dirt level coefficient and drainage rate to obtain the drum cleaning expectation value, and then using the drum cleaning expectation value to determine whether the washing machine meets the drum cleaning conditions.

[0086] It is understood that the method for determining the expected value of cylinder cleaning is not unique. In one embodiment, please refer to [link to relevant documentation]. Figure 8 Step 702 includes step 802.

[0087] Step 802: Determine the expected value of cylinder cleaning based on the current dirt level coefficient, drainage rate, and preset cylinder cleaning expectation model.

[0088] Specifically, the preset drum cleaning expectation model represents the correspondence between the current dirt level coefficient, drainage rate, and drum cleaning expectation value. In this embodiment, the controller has a preset drum cleaning expectation model stored in it. After the controller analyzes and obtains the current dirt level coefficient and drainage rate, it substitutes the current dirt level coefficient and drainage rate into the preset drum cleaning expectation model for analysis and calculation, thereby obtaining the drum cleaning expectation value corresponding to the current cleaning task.

[0089] It is understood that the specific type of the preset drum cleaning expectation model is not unique. In one embodiment, the preset drum cleaning expectation model includes: E = D * 1 / V, where E is the drum cleaning expectation value, D is the current dirt level coefficient, V is the drainage rate, and * indicates multiplication.

[0090] Please see Figure 9 In one embodiment, step 704 includes step 902.

[0091] Step 902: If the expected value for drum cleaning is greater than or equal to the preset expected threshold, determine that the washing machine meets the drum cleaning conditions.

[0092] Specifically, the preset expected threshold represents the minimum expected value for drum cleaning required when the washing machine needs drum cleaning. The controller stores this preset expected threshold. After the controller analyzes and calculates the expected value for drum cleaning, it compares it with the preset expected threshold to determine whether the washing machine meets the drum cleaning conditions. Accordingly, if the expected value for drum cleaning is greater than or equal to the preset expected threshold, the washing machine is considered to meet the drum cleaning conditions.

[0093] It should be noted that the method of obtaining the preset expected threshold is not unique. In one embodiment, it can be obtained by conducting experimental analysis on a washing machine of the same type in an experimental environment and stored in the controller.

[0094] Please refer to the following: Figure 10 To facilitate understanding of the technical solution of this application, the following detailed embodiments will be used to explain and illustrate this application.

[0095] After the washing machine completes one drum cleaning cycle, the turbidity parameters related to the drum cleaning program on the controller will be cleared, and the controller will re-record the turbidity. From the last drum cleaning cycle to the current washing cycle, the controller analyzes the historical turbidity parameters based on the turbidity data collected by the turbidity detector after the soaking phase in each washing cycle. Similarly, based on the turbidity data collected after the soaking phase in the current washing cycle, the current turbidity parameters are obtained.

[0096] The controller then calculates the average turbidity value by averaging historical and current turbidity parameters. This average turbidity value is then used to establish a predefined correspondence between average turbidity and dirtiness coefficients to determine the current dirtiness coefficient. Specifically, this is based on the average turbidity value... The specific location within the defined interval is matched. If the current dirt level coefficient is D1 or D2, it means the drum cleaning conditions are not met, and the washing task can continue according to the user's needs. If the current dirt level coefficient is D3 or D4, it indicates that the drum has become dirty to a certain extent. In this case, the controller will obtain the drainage rate of the last drain during the current washing task, substitute the current dirt level coefficient and drainage rate into E = D * 1 / V, and calculate the expected drum cleaning value.

[0097] Finally, the controller analyzes whether the expected value for drum cleaning is greater than or equal to the preset expected threshold. If the expected value is greater than or equal to the preset expected threshold, it indicates that the drum cleaning conditions are met, and a drum cleaning reminder will be pushed. If the expected value is less than the preset expected threshold, the cleaning task can continue to be executed according to the user's needs.

[0098] Based on the same inventive concept, this application also provides a washing machine control device for implementing the washing machine control method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more embodiments of the washing machine control device provided below can be found in the limitations of the washing machine control method described above, and will not be repeated here.

[0099] Please see Figure 11 A washing machine control device includes: a turbidity acquisition module 111, a cleaning detection module 113, and a cleaning reminder module 115.

[0100] The turbidity acquisition module 111 is used to acquire the current turbidity parameter; the current turbidity parameter is the turbidity parameter of the wastewater discharged from the drain outlet of the washing machine when the washing machine performs the current cleaning task; the cleaning detection module 113 is used to determine whether the washing machine meets the drum cleaning conditions based on the current turbidity parameter and the historical turbidity parameter; the historical turbidity parameter is the turbidity parameter of the wastewater discharged from the drain outlet during each cleaning task after the washing machine is first turned on or after the last drum cleaning task and before the current cleaning task is performed; the cleaning reminder module 115 is used to push drum cleaning reminder information if the washing machine meets the drum cleaning conditions.

[0101] In one embodiment, the cleaning detection module 113 is further configured to determine the average turbidity value based on the current turbidity parameter and the historical turbidity parameter; and to determine whether the washing machine meets the drum cleaning conditions based on the average turbidity value.

[0102] In one embodiment, the cleaning detection module 113 is further configured to determine the current dirt level coefficient based on the average turbidity value and the preset correspondence between the average turbidity value and the dirt level coefficient; and to determine whether the washing machine meets the drum cleaning conditions based on the current dirt level coefficient.

[0103] In one embodiment, the cleaning detection module 113 is further configured to determine that the washing machine meets the drum cleaning conditions if the current dirt level coefficient is greater than or equal to a preset coefficient threshold.

[0104] In one embodiment, the cleaning detection module 113 is further configured to, if the current dirt level coefficient is greater than or equal to a preset coefficient threshold, obtain the drainage rate of the last drainage when the washing machine performs the current cleaning task; and determine whether the washing machine meets the drum cleaning conditions based on the current dirt level coefficient and the drainage rate.

[0105] In one embodiment, the cleaning detection module 113 is further configured to determine the drum cleaning expectation value based on the current dirt level coefficient and drainage rate; and determine whether the washing machine meets the drum cleaning conditions based on the drum cleaning expectation value.

[0106] In one embodiment, the cleaning detection module 113 is further configured to determine the expected value of the cylinder cleaning based on the current dirt level coefficient, the drainage rate, and the preset cylinder cleaning expectation model.

[0107] In one embodiment, the cleaning detection module 113 is further configured to determine that the washing machine meets the drum cleaning conditions if the drum cleaning expectation value is greater than or equal to a preset expectation threshold.

[0108] The aforementioned washing machine control device acquires the current turbidity parameter of the wastewater discharged from the drain outlet each time the washing machine starts executing the current washing task. It then combines this data with historical turbidity parameters of the wastewater discharged from the drain outlet from the first start of the washing machine or the last time a drum cleaning task was executed, up to and including the current washing task, to analyze whether the washing machine meets the drum cleaning conditions. When the washing machine meets the drum cleaning conditions, a drum cleaning reminder message is sent to the user so that the user can perform drum cleaning promptly. This solution links drum cleaning with the turbidity of the wastewater discharged from the drain outlet, automatically analyzes whether the washing machine meets the drum cleaning conditions, and sends a drum cleaning reminder message to the user when the conditions are met. This eliminates the need for the user to manually determine whether to activate drum cleaning, thus solving the problem of drum cleaning being frequently activated or not activated even when the machine is severely dirty.

[0109] Each module in the aforementioned washing machine control device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device in hardware form, or stored in the memory of a computer device in software form, so that the processor can call and execute the operations corresponding to each module.

[0110] Please refer to the following: Figure 1A washing machine includes a cleaning drum 112, a housing 118, a turbidity detector 116, and a controller (not shown). The cleaning drum 112 is disposed inside the housing 118, and the housing 118 has a drain outlet 114. The drain outlet 114 is connected to the cleaning drum 112 through a pipe. The turbidity detector 116 is disposed at the drain outlet 114, and the controller is connected to the turbidity detector 116. The turbidity detector 116 is used to detect the turbidity parameters of the wastewater discharged from the drain outlet 114, and the controller is used to execute the steps of the washing machine control method described above.

[0111] Specifically, the washing machine control method is as shown in the above embodiments and accompanying drawings, and will not be repeated here. In the above-described washing machine, whenever the washing machine starts to execute the current washing task, it obtains the current turbidity parameter of the wastewater discharged from the drain outlet 114, and combines this with the historical turbidity parameters of the wastewater discharged from the drain outlet 114 during each washing task from the first start of the washing machine or the last time a drum cleaning task was executed until the current washing task is executed, to analyze whether the washing machine meets the drum cleaning conditions. When the washing machine meets the drum cleaning conditions, a drum cleaning reminder message is pushed so that the user can clean the washing machine in time. The above solution links the drum cleaning of the washing machine with the turbidity of the wastewater discharged from the drain outlet 114, automatically analyzes whether the washing machine meets the drum cleaning conditions, and pushes a drum cleaning reminder message to remind the user when the drum cleaning conditions are met, eliminating the need for the user to manually determine whether to start drum cleaning, thus solving the problem of drum cleaning being frequently started or not started when severely dirty.

[0112] Please see Figure 1 In one embodiment, the washing machine also includes a flow rate detector 119, which is disposed at the drain outlet 114 and connected to a controller (not shown).

[0113] Specifically, the washing machine's drain outlet 114 is equipped with a flow rate detector 119, which can collect the water flow rate during the washing machine's drainage process. Furthermore, the corresponding washing machine control method can be executed simply by using the flow rate corresponding to the last drainage operation of the washing task as the drainage rate.

[0114] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0115] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
