Technical Field
[0001] This application relates to the field of garment processing equipment, and more specifically, to a washing control method, electronic equipment, and garment processing equipment for garment processing. Background Technology
[0002] Currently, with the continuous improvement of intelligent home appliance technology, clothing processing equipment is usually equipped with multi-stage control programs that include pre-wash and main wash.
[0003] In related technologies, the pre-wash stage of garment processing equipment operates with fixed preset values. After the pre-wash is completed, only a few parameters, such as detergent dosage and water volume, are simply adjusted based on the turbidity test results of the wash water. This can lead to insufficient pre-washing of heavily soiled clothes, making it impossible to effectively remove stains through the pre-washing process, resulting in insufficient cleaning efficiency in the main wash stage. At the same time, it can also easily lead to over-pre-washing of lightly soiled clothes, resulting in waste of water, electricity, and detergent. Summary of the Invention
[0004] In view of this, this application provides a washing control method, electronic device and washing equipment for a garment processing device, so as to improve the washing effect of clothes while reducing the energy consumption of the washing process.
[0005] In a first aspect, this application provides a washing control method for a garment processing device, comprising: entering a pre-soaking stage and obtaining water quality information of the washing water in the pre-soaking stage, wherein the pre-soaking stage uses a lower washing water volume than the pre-washing stage to wet the clothes to be washed in the tub, and the stains on the clothes to be washed can be dissolved in the washing water in the pre-soaking stage. The decision to proceed to the pre-wash stage or skip the pre-wash stage and proceed to the main wash stage is determined based on the water quality information of the washing water during the pre-soaking stage.
[0006] By employing the above technical solution, a pre-soaking stage is set up with a lower water volume than the pre-wash stage. Only a small amount of water is used to wet the clothes to be washed, allowing surface stains to naturally dissolve into the washing water during the pre-soaking stage. The water quality information from the pre-soaking stage is used to differentiate the degree of soiling of the clothes, determining whether to proceed to the pre-wash stage or skip it and go directly to the main wash stage. This allows for adaptive washing based on the actual soiling level of the clothes. When the clothes are only lightly soiled, the pre-wash stage can be omitted, reducing unnecessary water, electricity, and detergent consumption. When the clothes are heavily soiled, the pre-wash stage is initiated to soften the fabric fibers and dissolve some soluble stains, reducing the washing load on the subsequent main wash stage, improving washing efficiency and cleanliness, and reducing energy consumption.

The set washing parameters for the main wash stage are corrected according to the washing parameter correction coefficient of the main wash stage to obtain the corrected main wash washing parameters. The set washing parameters for the main wash stage are the set washing parameters for the main wash stage corresponding to the washing mode set by the user.
[0012] In an optional implementation of the washing control method for the aforementioned garment processing equipment, the step of correcting the set washing parameters for the main wash stage according to the washing parameter correction coefficient for the main wash stage to obtain the corrected main wash parameters includes: The set washing parameters are a parameter group containing multiple operating parameters, parameter group P=(P1, P2, P3, Pi, ..., Pm), where m≥1; The washing parameter correction coefficient K is a product of multiple coefficients, K=K1*K2*…*Kj…*Kn; where n≥2; The corrected main wash parameter P' is the product of the wash parameter correction coefficient K and the parameter group P, P'=K*(P1, P2, P3, ..., Pm)=(KP1, KP2, KP3, ..., KPm); Among them, the operating parameters in the parameter group include at least one or more of the main wash duration, main wash temperature, and main wash speed; Wherein, Pi represents the i-th operating parameter in the set washing parameter group, and i is a positive integer ranging from 1 to m; Kj is the j-th correction coefficient determined based on the water quality information of the washing water body in the pre-soaking stage and the water quality information of the washing water body in the pre-washing stage, and j is a positive integer ranging from 1 to n.

[0025] Currently, with the continuous improvement of intelligent home appliance technology, clothing processing equipment is usually equipped with multi-stage control programs that include pre-wash and main wash.
[0026] In related technologies, the pre-wash stage of garment processing equipment operates with fixed preset values. After the pre-wash is completed, only a few parameters, such as detergent dosage and water volume, are simply adjusted based on the turbidity test results of the wash water. This can lead to insufficient pre-washing of heavily soiled clothes, making it impossible to effectively remove stains through the pre-washing process, resulting in insufficient cleaning efficiency in the main wash stage. At the same time, it can also easily lead to over-pre-washing of lightly soiled clothes, resulting in waste of water, electricity, and detergent.
[0027] To improve the washing effect of clothes, this application provides a washing control method, electronic equipment, and clothes washing equipment for a clothes processing device.
[0028] Combination Figure 1 As shown, this application provides a washing control method for a garment processing device, comprising: S11, enter the pre-soaking stage and obtain the water quality information of the washing water in the pre-soaking stage. The pre-soaking stage uses a lower amount of washing water than the pre-washing stage to wet the clothes to be washed in the tub, and the stains on the clothes to be washed can be dissolved in the washing water in the pre-soaking stage.
[0029] Optionally, the garment processing equipment has at least a pre-wash stage and a main wash stage. In this solution, after the user puts the clothes to be washed into the washing tub, they can select the washing mode and stain type through the operation interface of the garment processing equipment.
[0030] Based on the washing mode selected by the user, the set washing parameters for the main wash stage can be determined. These set washing parameters are the set washing parameters corresponding to the washing mode selected by the user.
[0031] The washing modes can include different fabric types such as cotton, linen, synthetic fibers, wool, and silk; the stain types include different types such as everyday stains, heavy oil stains, sweat stains, and juice stains.
[0032] Furthermore, one or more weight sensors are installed at the bottom of the washing tub. The initial weight of the clothes to be washed is detected by the weight sensors.
[0033] Optionally, if a single weight sensor is provided, it is located at the bottom of the washing tub. Exemplarily, it can be mounted on a central connecting bracket between the bottom of the washing tub and the drive unit, or located at a central support base at the bottom of the washing tub. This single-weight sensor arrangement results in a simple and compact structure, convenient installation and maintenance, effectively reducing equipment manufacturing costs while meeting basic initial weight detection requirements for clothing.
[0034] Optionally, if multiple weight sensors are provided, they can be evenly spaced around the circumference of the bottom of the washing tub. For example, they can be installed at the lower connecting seats of multiple suspension springs at the bottom of the washing tub, or at the upper mounting seats of multiple shock absorbers supporting the washing tub. This multi-point distributed arrangement of weight sensors effectively counteracts the influence of uneven load distribution of clothes within the washing tub on the weight detection results, significantly improving the accuracy and stability of the initial weight detection and providing a more reliable data foundation for the accurate matching of subsequent washing parameters.
[0035] Optionally, based on the washing mode selected by the user, the corresponding set washing parameters for the main wash stage can be retrieved from a preset parameter database. These set washing parameters include one or more of the following: main wash duration, main wash temperature, main wash spin speed, main wash detergent dosage, and main wash water volume.
[0036] For example, different fabric types correspond to different main wash parameters. For instance, cotton and linen fabrics have a higher main wash temperature and a faster spin speed, while wool and silk fabrics have a lower main wash temperature and a slower spin speed, in order to protect the fabric from damage.
[0037] Furthermore, after the clothes to be washed are placed in the washing tub, the garment processing equipment first enters the pre-soaking stage. During this stage, the clothes to be washed are moistened by injecting a lower volume of washing water than in the pre-washing stage, and the stains on the clothes are dissolved in the washing water in the pre-soaking stage.
[0038] Furthermore, the degree of soiling of the clothes to be washed can be determined based on the water quality information of the washing water during the pre-soaking stage. This water quality information includes at least the turbidity and pH values of the washing water during the pre-soaking stage. The pH value referred to here is the acidity or alkalinity of the washing water.
[0039] Among them, the water quality information of the washing water body during the pre-soaking stage can be determined once after the pre-soaking stage is completed.
[0040] Optionally, the water quality information of the washing water in the pre-soaking stage can be detected during the drainage process; or, the detection can be completed in the washing tub after the pre-soaking stage is completed, and the water quality information of the washing water in the pre-soaking stage can be used to determine whether the washing water in the pre-soaking stage should be discharged.
[0041] Alternatively, water quality information of the wash water can be obtained multiple times during the pre-soaking stage, and the average value of the multiple water quality measurements can be used to determine the water quality information of the wash water in the pre-soaking stage. That is, the turbidity value of the wash water can be obtained multiple times during the pre-soaking stage, and the turbidity value of the wash water in the pre-soaking stage can be determined based on the average value of the multiple turbidity measurements; and the pH value of the wash water can be obtained multiple times during the pre-soaking stage, and the pH value of the wash water in the pre-soaking stage can be determined based on the average value of the multiple pH values.
[0042] Alternatively, water quality information of the wash water can be obtained multiple times during the pre-soaking stage, and the maximum value of the multiple water quality measurements can be determined as the water quality information of the wash water in the pre-soaking stage. That is, the turbidity value of the wash water can be obtained multiple times during the pre-soaking stage, and the maximum value among the multiple turbidity values can be determined as the turbidity value of the wash water in the pre-soaking stage; and the pH value of the wash water can be obtained multiple times during the pre-soaking stage, and the maximum value among the multiple pH values can be determined as the pH value of the wash water in the pre-soaking stage.
[0043] Alternatively, the water quality information of the wash water in the pre-soaking stage may also include microbial values. The microbial values of the wash water in the pre-soaking stage can characterize the degree of microbial contamination on the clothes to be washed, and can also serve as an auxiliary basis for whether to enter the pre-wash stage, and for adjusting the pre-wash washing parameters and / or the main wash washing parameters.
[0044] Specifically, if the microbial value is low, the turbidity value of the washing water in the pre-soaking stage is low, and the pH value of the washing water in the pre-soaking stage is between the first and second pH thresholds, then it is determined to enter the main wash stage.
[0045] If the microbial count is high, and / or the turbidity of the washing water in the pre-soaking stage is not low and the pH of the washing water in the pre-soaking stage is not between the first and second pH thresholds, then the pre-washing stage is determined to begin.
[0046] If the microbial count is high, the washing temperature and washing time of the pre-wash and / or main wash water should be increased accordingly.
[0047] Specifically, the turbidity value of the washing water during the pre-soaking stage can characterize the content of insoluble solid stains that have been removed from the clothes to be washed. The higher the turbidity value, the more insoluble stains such as mud, dust, and fiber debris are on the clothes. The pH value of the washing water during the pre-soaking stage can characterize the type and content of water-soluble stains that have dissolved on the clothes to be washed. The greater the deviation of the pH value from the neutral range, the higher the content of water-soluble stains such as sweat, juice, and oil on the clothes.
[0048] Optionally, the amount of water used in the pre-wash stage is related to the total water volume of the washing tub. For example, the amount of water used in the pre-wash stage is 8% of the total water volume. This ensures that the clothes are fully soaked, allowing stains to dissolve effectively in the pre-soaking water, while avoiding water waste caused by excessive water usage. It also prevents excessive dilution of stains by large amounts of water, ensuring that water quality tests in the subsequent pre-soaking stage accurately reflect the degree of soiling of the clothes.
[0049] Optionally, the washing water volume below the pre-wash stage can be set to N% of the full water volume of the washing tub. Here, the full water volume of the washing tub refers to the standard washing water volume calibrated by the garment processing equipment and corresponding to the rated maximum washing capacity, that is, the nominal water volume of the washing tub under rated maximum load conditions to meet normal washing needs.
[0050] Optionally, the amount of water used in the pre-wash stage should be less than or equal to 15% of the full drum volume. By controlling the amount of water used in the pre-soak stage within this range, the soil concentration in the pre-soak water can be maintained while ensuring proper wetting of the clothes, thus improving the sensitivity of water quality detection. Simultaneously, water consumption in the pre-soak stage is reduced, preventing excessive wasted water even if the main wash stage is subsequently initiated, thus balancing detection accuracy with water conservation.
[0051] Optionally, a flow detection device can be installed at the water inlet of the washing tub to determine the amount of water injected into the washing tub.
[0052] Alternatively, the amount of washing water below the pre-wash stage can also be determined based on the liquid level. That is, the full-tub liquid level corresponding to the full water volume in the washing tub is pre-calibrated, and the amount of washing water below the pre-wash stage is set as a proportional value corresponding to the full-tub liquid level. A liquid level detection device installed on the side wall of the washing tub collects the water level in real time. When the water level detected by the detection device reaches the set liquid level, the water intake is stopped to complete the addition of the washing water below the pre-wash stage. This liquid level determination method does not rely on water flow statistics, adapts to water intake control under different water pressures, has a simple structure, and a stable detection method. It can stably maintain the water volume in the pre-soaking stage, ensuring that the soaking effect on the clothes is consistent with the stain concentration of the washing water in the pre-soaking stage.
[0053] S12, determine whether to enter the pre-wash stage or skip the pre-wash stage and enter the main wash stage based on the water quality information of the washing water body in the pre-soaking stage.
[0054] In this solution, by detecting the water quality information of the washing water during the pre-soaking stage, it can be determined whether to proceed to the pre-wash stage or skip it. This allows for the identification of the degree of soiling on the clothes to be washed, while simultaneously detecting both insoluble solid stains and water-soluble stains.
[0055] Based on this, determine whether to enter or skip the pre-wash stage: For lightly soiled clothes, skip the pre-wash stage and proceed directly to the main wash stage to avoid the ineffective consumption of water, electricity, and detergent caused by always entering the pre-wash stage; for heavily soiled clothes, enter the pre-wash stage to pre-treat the stains in advance, providing a guarantee for the washing effect of the subsequent main wash stage and solving the problem of poor cleanliness when heavily soiled clothes go directly into the main wash stage.
[0056] Furthermore, the turbidity and pH values of the washing water during the pre-soaking stage can provide basic data support for the adaptive matching of subsequent pre-wash parameters and the dynamic correction of main wash parameters. This will be explained in detail later.
[0057] By employing the above technical solution, a pre-soaking stage is set up with a lower water volume than the pre-wash stage. Only a small amount of water is used to wet the clothes to be washed, allowing surface stains to naturally dissolve into the washing water during the pre-soaking stage. The water quality information from the pre-soaking stage is used to differentiate the degree of soiling of the clothes, determining whether to proceed to the pre-wash stage or skip it and go directly to the main wash stage. This allows for adaptive washing based on the actual soiling level of the clothes. When the clothes are only lightly soiled, the pre-wash stage can be omitted, reducing unnecessary water, electricity, and detergent consumption. When the clothes are heavily soiled, the pre-wash stage is initiated to soften the fabric fibers and dissolve some soluble stains, reducing the washing load on the subsequent main wash stage, improving washing efficiency and cleanliness, and reducing energy consumption.
[0058] In an optional implementation of the washing control method for the aforementioned garment processing equipment, the washing control method further includes: if it is determined that the pre-washing stage is to be entered, determining the pre-washing parameters for the pre-washing stage based on the water quality information of the washing water in the pre-soaking stage and the washing information of the garment to be washed.
[0059] In an optional implementation of the washing control method for the aforementioned garment processing equipment, the pre-wash parameters for the pre-wash stage are determined based on the water quality information of the washing water in the pre-soaking stage and the washing information of the garments to be washed. This includes: inputting the user-set washing mode, the user-set stain type, the initial weight of the garments to be washed, the turbidity value of the washing water in the pre-soaking stage, and the pH value of the washing water in the pre-soaking stage into a pre-trained prediction model, and outputting and determining the pre-wash parameters.
[0060] The water quality information for the washing water includes the turbidity and pH value of the washing water; the washing information for the clothes to be washed in the tub includes the initial weight of the clothes to be washed, the washing mode set by the user, and the type of stain set by the user.
[0061] In this solution, the pre-trained prediction model is a machine learning model trained on a large amount of historical washing data. This model takes washing mode, stain type, initial garment weight, pH value of the washing water during the pre-soaking stage, and turbidity value of the washing water during the pre-soaking stage as input features, and outputs optimal pre-wash parameters. By outputting pre-wash parameters through the prediction model, adaptive matching of pre-wash parameters can be achieved, ensuring that the washing intensity during the pre-wash stage is accurately matched to the actual degree of soiling, fabric type, and stain type of the garment. This guarantees the pre-washing effect while avoiding resource waste caused by over-pre-washing.
[0062] It should be noted that the pre-trained prediction model employs at least three fully connected neural networks. The input layer has at least five neurons to correspond to the user-selected washing mode, stain type, initial weight of the clothes, turbidity of the washing water during the pre-soaking stage, and pH value of the washing water during the pre-soaking stage. The output layer has at least four neurons to correspond to the output of pre-wash detergent dosage, pre-wash water volume, pre-wash temperature, and pre-wash duration. The model's training dataset contains over 100,000 sets of historical washing data for different washing scenarios. Each set of data includes input features and corresponding optimal pre-wash parameter labels, and the training iterations are at least 1000 times.
[0063] Specifically, the processing of the prediction model in this scheme is divided into three stages: parameter acquisition, model training, and model application.
[0064] During the parameter collection phase, the user-selected washing mode X, the user-selected stain type Z, the initial weight of the clothes G, the turbidity value N of the washing water during the pre-soaking phase, and the pH value Y of the washing water during the pre-soaking phase all affect the amount of pre-wash detergent (g) used in the pre-washing phase. 洗 Pre-wash water volume (g) 水 The key factors are the pre-wash duration (t) and pre-wash temperature (T). Therefore, these key parameters must be comprehensively collected during the parameter acquisition phase. When the user uses the washing machine, they are asked to select the type of soiling on the clothes and the washing mode. The selected soiling type (Z) and washing mode (X) are recorded. After the wash begins, the initial weight (G) of the clothes is obtained by weighing. After adding less washing water than in the pre-wash stage to dissolve the stains on the clothes, the turbidity (N) and pH (Y) of the washing water in the pre-soaking stage are measured. These parameters are input into the model to obtain the optimal pre-wash detergent dosage (g) for the pre-wash stage. 洗 Pre-wash water volume (g) 水 Pre-wash duration t and pre-wash temperature T.
[0065] In other words, during the model training phase, the model's inputs are the user-selected washing mode X, the user-selected stain type Z, the initial weight of the clothes G, the turbidity value N of the washing water during the pre-soaking stage, and the pH value Y of the washing water during the pre-soaking stage. The output is the amount of detergent used in the pre-wash stage (g). 洗 Pre-wash water volume (g) 水 Pre-wash duration t and pre-wash temperature T.
[0066] Since the model is a multiple-input multiple-output problem, this application uses a neural network model to achieve the above functions. A massive and diverse dataset, covering different user-selected washing modes, user-selected stain types, initial weight of clothes, turbidity value of washing water during the pre-soaking stage, pH value of washing water during the pre-soaking stage, and optimal pre-wash detergent dosage, pre-wash water volume, pre-wash duration, and pre-wash temperature, is sent to the model via a network transmission protocol.
[0067] The core objective of model training is to establish the mapping relationship between the user-selected washing mode, the user-selected stain type, the initial weight of the clothes, the turbidity value of the washing water during the pre-soaking stage, the pH value of the washing water during the pre-soaking stage, and the optimal amount of pre-wash detergent, the amount of pre-wash water, the pre-washing time, and the pre-washing temperature.
[0068] The user's selected washing mode X determines the fabric type of the clothes to be washed.
[0069] Based on the fabric and weight of the garments, the pre-wash parameters (including pre-wash water volume, pre-wash detergent dosage, pre-wash temperature, and pre-wash duration) can be determined, as shown in Table 1: Table 1 Basic Parameters of Clothing of Different Materials and Weights
[0070] In addition, the coefficients for different factors are shown in Table 2: Table 2. Coefficients of different factors
[0071] The reasons why the turbidity of the washing water during the pre-soaking stage, the pH value of the washing water during the pre-soaking stage, and the type of stain selected by the user affect the amount of pre-wash water, the amount of pre-wash detergent, the pre-washing time, and the pre-washing temperature are as follows: a. Turbidity effect: The amount of water needs to be increased accordingly to fully dilute high-concentration stains and prevent stains from being re-adsorbed onto the fabric surface due to oversaturation; the amount of detergent needs to be increased to improve the stain decomposition efficiency; the pre-wash time needs to be extended to ensure that the detergent fully penetrates and softens stubborn stains; a higher washing temperature (such as above 40℃) is used to accelerate the emulsification and decomposition of grease stains.
[0072] b. Dynamic control of pH value: Alkaline environment (pH > 7) promotes the saponification reaction of oils and fats, requiring increased water volume to dilute the saponification products and increased detergent concentration to ensure effective saponification. The saponification reaction rate increases significantly with increasing temperature, requiring extended treatment time to complete the reaction. Acidic environment (pH < 7) optimizes the hydrolysis efficiency of protein stains (such as blood stains and sweat stains). The hydrolysis reaction is already highly efficient at low temperatures, so the water temperature can be lowered to avoid fabric damage. The amount of detergent needs to be precisely matched to the specific stain, reducing water demand.
[0073] c. Stain type and parameter matching: The different chemical properties of different stain types (such as grease, protein, pigment) require the system to dynamically match core parameters such as water volume, detergent concentration, temperature and pre-wash time to achieve the optimal balance between stain removal efficiency and fabric protection.
[0074] Furthermore, referring to Table 3, in the model application stage, for example: before the start of this wash, the user selects washing mode X and stain type Z. After the wash begins, the initial weight G of the clothes is obtained by weighing. After injecting less washing water than in the pre-wash stage, the turbidity sensor obtains the turbidity value N of the washing water in the pre-soak stage, and the acid-base sensor obtains the acid-base value Y of the washing water in the pre-soak stage. X, Z, G, N, and Y are input into the model, and the model, through learning and calculation, can obtain the pre-wash water volume g. 水 Pre-wash detergent dosage (g) 洗 Pre-wash duration t, pre-wash temperature T.
[0075] Table 3 Example of parameter comparison table
[0076] In addition, this solution can install a turbidity detection device and a pH value detection device in the drain pipe of the washing tub. The turbidity detection device can determine the turbidity value of the washing water during the pre-soaking stage; the pH value detection device can determine the pH value of the washing water during the pre-soaking stage.
[0077] Furthermore, water quality testing can be conducted by draining a pre-soaked volume of water from the washing stage, rather than directly testing inside the washing tub. This avoids interference from factors such as clothing obstructing the view, water flow disturbance, and air bubbles within the washing tub, thus improving the accuracy of water quality testing.
[0078] Optionally, the turbidity detection device and the pH value detection device are installed in a straight section connected to the washing tub, so that the water quality sensor can have full and stable contact with the water sample, thereby further improving the detection accuracy and result repeatability.
[0079] Alternatively, the turbidity detection device and the pH value detection device can be installed at the drain outlet.
[0080] Optionally, the preset water volume is 1 / 3 to 2 / 3 lower than the washing water volume in the pre-wash stage. This satisfies the minimum detection water volume requirements of the turbidity and pH value detection devices, ensuring a good signal-to-noise ratio, without causing excessive water waste, and without significantly affecting the overall water balance of subsequent washing programs. For example, the preset water volume is 1 / 2 lower than the washing water volume in the pre-wash stage.
[0081] By draining the washing water from the pre-soaking stage, the water quality information of the washing water can be determined. This effectively eliminates the adverse effects of complex environmental factors such as clothing obstruction, water flow disturbance, and bubble interference in the washing tub on water quality testing, improves the detection accuracy and repeatability of turbidity and pH values, and balances water conservation requirements with detection reliability. It also provides data support for the accurate determination of whether to enter the pre-wash stage and the adaptive matching of pre-wash parameters.
[0082] Furthermore, since the pre-soaking stage uses only clean water without any detergent, dissolving only some soluble stains and a small amount of insoluble solid particles from the surface of the clothes, the water quality is relatively clean. Therefore, after draining the preset amount of water, the remaining pre-soaking stage water can be reused in the subsequent pre-wash or main wash stages to further reduce the total water consumption of the washing process and improve water resource utilization efficiency. Specifically, if it is determined that the pre-wash stage is required, the remaining pre-soaking stage water can be used directly as the base amount of pre-wash water. Only the remaining pre-wash water needs to be added according to the pre-wash parameters and heated to the pre-wash temperature; there is no need to drain all the pre-soaking stage water and refill it. If it is determined that the main wash stage is to be started directly, the remaining pre-soaking stage water can be used as part of the main wash water, mixed with the subsequently added main wash water, thereby effectively reducing ineffective water discharge and achieving tiered utilization of water resources.
[0083] Alternatively, the turbidity and pH levels can be located at the bottom of the washing tub. This allows for the determination of the water quality in the pre-soaking stage without draining the water. Consequently, this water can be directly used in subsequent pre-wash or main wash stages, reducing water waste.
[0084] In an optional implementation of the washing control method for the aforementioned garment processing equipment, the pre-wash parameters include pre-wash dosage, pre-wash water volume, pre-wash temperature, and pre-wash duration; the pre-wash stage includes: According to the pre-wash temperature and pre-wash water volume, the washing water for the pre-wash stage is injected into the washing tub of the garment processing equipment, and after the detergent is injected according to the pre-wash dosage, the clothes to be washed are soaked for the first preset time.
[0085] Control the washing tub to rotate continuously at the preset pre-wash speed for a second preset time.
[0086] Control the discharge of washing water during the pre-wash stage from the washing tub.
[0087] The duration for the washing tub to discharge the washing water during the pre-washing stage is the third preset duration. The pre-wash duration is the sum of the first preset duration, the second preset duration, and the third preset duration; and the first preset duration and the third preset duration are both less than the second preset duration.
[0088] Specifically, after entering the pre-wash stage, firstly, pre-wash water heated to the pre-wash temperature is poured into the washing tub, along with the calculated pre-wash detergent dosage. Then, the clothes are soaked in the pre-wash water for a first preset time, allowing the detergent to fully work and break down and soften stains on the clothes. Next, the washing tub is controlled to rotate continuously at a preset pre-wash speed for a second preset time, using mechanical force to remove stains from the clothes. Finally, the washing tub is controlled to drain the washing water.
[0089] It should be noted that the process of draining the washing water from the washing tub includes: draining the washing water after the washing tub stops rotating. The time taken from when the washing tub starts to reduce its speed until it stops rotating and until all the washing water is drained is the third preset time.
[0090] Alternatively, if the turbidity of the washing water during the pre-soaking stage is low and the pH value is within the neutral threshold range, then no drainage is performed, allowing the washing water from the pre-wash stage to directly participate in the subsequent main wash stage. In this case, the pre-wash duration only includes the first preset duration and the second preset duration.
[0091] If the turbidity of the washing water in the pre-soaking stage is medium and the pH value of the washing water in the pre-soaking stage deviates slightly from the neutral range, then 1 / 3 to 3 / 4 of the washing water in the pre-washing stage should be discharged, and some water should be retained for the main washing process.
[0092] If the turbidity of the washing water in the pre-soaking stage is high or the pH value of the washing water in the pre-soaking stage deviates significantly from the neutral range, then all the washing water should be drained to prevent highly soiled water from being carried into the main wash stage and affecting the washing effect.
[0093] Optionally, the third preset duration can be controlled by adjusting the opening degree of the drain valve, the operating power of the drain pump, and the cross-sectional area of the drain pipe.
[0094] Optionally, the first preset duration is 3 min to 10 min, the second preset duration is 2 min to 8 min, and the third preset duration is 1 min to 3 min.
[0095] For example, the first preset time is 3 minutes, the second preset time is 6 minutes, the third preset time is 3 minutes, and the total pre-wash time is 12 minutes.
[0096] Optionally, the ratio of the first preset duration, the second preset duration, and the third preset duration is 1:2:1. This allows for a more reasonable allocation of duration among the three core stages of the pre-washing process, matching the functional positioning and intensity of each stage.
[0097] The pre-wash process is divided into three stages: a first, pre-set soaking stage, and a third, pre-draining stage. The first pre-wash stage, lasting half the total time, ensures that the detergent fully penetrates the fabric fibers, activating its active ingredients and initially breaking down and softening stains. The second pre-wash stage, lasting half the total time, is the core of the pre-wash process. Through continuous mechanical agitation, it effectively removes softened stains from the fabric surface and fiber gaps, dispersing them into the wash water. The third pre-wash stage, lasting half the total time, ensures that the wash water from the pre-wash stage is completely drained, preventing residual high-concentration dirty water from entering the main wash stage and affecting its performance. This time ratio optimizes the total pre-wash time while ensuring effective pre-washing, avoiding the problems of reduced washing efficiency due to excessively long pre-wash stages or insufficient functionality due to excessively short pre-wash stages.
[0098] Optionally, a preset pre-wash speed can be set lower than the main wash speed, typically 100-200 rpm. This gentle washing method ensures effective stain removal while avoiding tangling, pulling, and abrasion of clothing caused by high-speed rotation, making it particularly suitable for pre-washing delicate fabrics such as wool and silk. During the soaking stage, the washing tub can be controlled to perform intermittent low-speed forward and reverse rotation, each rotation lasting 5-10 seconds with an interval of 1-2 minutes. This promotes even penetration of detergent into the clothing, accelerating the stain decomposition process and improving the pre-wash effect.
[0099] Through the aforementioned phased washing process, the pre-wash stage achieves a combination of chemical and mechanical action, providing tailored pre-wash treatments for different fabric types, stain types, and levels of soiling. This effectively removes surface stains and most soluble stains, reducing the washing burden during the main wash and improving overall cleanliness.
[0100] Meanwhile, since the pre-wash parameters are adaptively determined based on the water quality information of the washing water during the pre-soaking stage, as well as the washing mode, stain type, and initial weight of the clothes selected by the user, it can avoid the problem of over-pre-washing in the traditional fixed parameter pre-wash mode and reduce the consumption of water, electricity, and detergent.
[0101] In addition, by using a gentler pre-wash spin speed and preset time allocation, it can effectively protect clothing fibers from damage, extend the service life of clothing, and provide users with a more efficient, energy-saving, and garment-care-friendly washing experience.
[0102] In an optional implementation of the washing control method for the aforementioned garment processing equipment, the washing control method further includes: after entering the pre-wash stage, acquiring the water quality information of the washing water body in the pre-wash stage; and determining the main wash parameters for the main wash stage based on the water quality information of the washing water body in the pre-soak stage and the water quality information of the washing water body in the pre-wash stage.
[0103] After entering the pre-wash stage, obtaining the water quality information of the washing water in the pre-wash stage means obtaining the water quality information of the washing water in the pre-wash stage after the pre-wash stage is completed. Then, based on the water quality information of the washing water in the pre-soak stage and the water quality information of the washing water in the pre-wash stage, the main wash parameters for the main wash stage are determined.
[0104] This solution determines the degree of stain treatment during the pre-wash process based on water quality changes in both stages. Therefore, it no longer relies solely on water quality information from either the pre-soaking or pre-wash stages as the basis for parameter settings. Instead, it combines both to adjust the main wash duration, temperature, and spin speed. This allows for adjustments to the main wash cycle when the pre-wash treatment is effective, reducing energy and material consumption; conversely, it enables a more robust main wash cycle when the pre-wash treatment is less effective, enhancing the washing process and making the washing process more closely reflect the actual soiling changes of the clothes.
[0105] In this solution, the method for detecting the water quality information of the washing water in the pre-wash stage is the same as the method for detecting the water quality information of the washing water in the pre-soaking stage. That is: Optionally, a test can be performed after the pre-wash stage to determine the water quality information of the wash water in the pre-wash stage. This water quality information can be detected during the drainage process of the wash water from this stage; alternatively, it can be detected inside the washing tub after the pre-wash stage, and the water quality information from the pre-wash stage can be used to determine whether the wash water from the pre-wash stage should be discharged. The turbidity detection device and the pH detection device can be installed in one or more locations, such as inside the drain pipe, at the drain outlet, and at the bottom of the washing tub.
[0106] Alternatively, water quality information of the wash water can be obtained multiple times during the pre-soaking stage, and the average value of the water quality information from multiple tests can be used to determine the water quality information of the wash water in the pre-washing stage. That is, the turbidity value of the wash water is obtained multiple times during the pre-soaking stage, and the turbidity value of the wash water in the pre-washing stage is determined based on the average value of the turbidity values from multiple tests; and the pH value of the wash water is obtained multiple times during the pre-soaking stage, and the pH value of the wash water in the pre-washing stage is determined based on the average value of the pH values from multiple tests.
[0107] Alternatively, water quality information of the wash water can be obtained multiple times during the pre-soaking stage, and the maximum value of the multiple water quality measurements can be determined as the water quality information of the wash water in the pre-washing stage. That is, the turbidity value of the wash water can be obtained multiple times during the pre-soaking stage, and the maximum value among the multiple turbidity measurements can be determined as the turbidity value of the wash water in the pre-washing stage; and the pH value of the wash water can be obtained multiple times during the pre-soaking stage, and the maximum value among the multiple pH values can be determined as the pH value of the wash water in the pre-washing stage.
[0108] Combination Figure 2 As shown, based on the water quality information of the washing water in the pre-soaking stage and the washing water in the pre-washing stage, the main wash parameters for the main wash stage are determined, including: S21, determine the correction coefficient of the washing parameters for the main wash stage based on the water quality information of the washing water in the pre-soaking stage and the washing water in the pre-washing stage.
[0109] S22, the set washing parameters for the main wash stage are corrected according to the washing parameter correction coefficient of the main wash stage to obtain the corrected main wash washing parameters.
[0110] The washing parameters for the main wash stage are the same as the washing parameters for the main wash stage that correspond to the user-defined washing mode.
[0111] This solution comprehensively considers the water quality information of the washing water in the pre-soaking stage and the washing water in the pre-washing stage. It combines the dirt status of the washing water in the pre-soaking stage with the actual cleaning effect in the pre-washing stage, thereby enabling dynamic adjustment of the main wash parameters. This avoids the problem of insufficient or excessive washing caused by fixed main wash parameters, and maximizes the reduction of washing energy consumption while ensuring the cleaning effect.
[0112] In an optional implementation of the washing control method for the aforementioned garment processing equipment, the set washing parameters for the main wash stage are corrected according to a correction coefficient for the washing parameters of the main wash stage, resulting in corrected main wash parameters, including: Set the washing parameters as a parameter group containing multiple operating parameters, parameter group P=(P1, P2, P3, Pi, ..., Pm), where m≥1; The washing parameter correction coefficient K is a product of multiple coefficients, K=K1*K2*…*Kj…*Kn; where n≥2; The corrected main wash parameter P' is the product of the wash parameter correction coefficient K and the parameter group P, P'=K*(P1, P2, P3, ..., Pm)=(KP1, KP2, KP3, ..., KPm); Among them, the operating parameters in the parameter group include at least one or more of the main wash duration, main wash temperature, and main wash speed; Where Pi represents the i-th operating parameter in the set washing parameter group, and i is a positive integer ranging from 1 to m; Kj is the j-th correction coefficient determined based on the water quality information of the washing water body in the pre-soaking stage and the water quality information of the washing water body in the pre-washing stage, and j is a positive integer ranging from 1 to n.
[0113] In this solution, the corrected main wash parameters are determined by multiplying the parameter set with the wash parameter correction coefficient. This enables synchronous and proportional correction of multiple operating parameters during the main wash stage, ensuring the matching and coordination between various wash parameters and avoiding the imbalance of wash logic caused by adjusting a single parameter individually. Furthermore, this calculation method is logically simple, requires minimal computation, and is compatible with the computing power of embedded processors in garment processing equipment, ensuring the real-time performance and stability of the control process.
[0114] Combination Figure 3 As shown, the correction coefficients for the washing parameters in the main wash stage are determined based on the water quality information of the washing water in the pre-soaking stage and the washing water in the pre-washing stage, including: S31. Determine the turbidity change value based on the difference between the turbidity value of the washing water in the pre-washing stage and the turbidity value of the washing water in the pre-soaking stage.
[0115] Among them, the turbidity change value can characterize the removal effect of the pre-washing stage on insoluble stains.
[0116] The greater the change in turbidity, the more insoluble stains are removed in the pre-washing stage, and the better the pre-washing effect; conversely, the smaller the change in turbidity, the less insoluble stains are removed in the pre-washing stage, and the worse the pre-washing effect.
[0117] S32, determine the first coefficient based on the turbidity value of the washing water during the pre-washing stage.
[0118] Specifically, the first coefficient is determined based on the turbidity level corresponding to the turbidity value of the wash water during the pre-wash stage. The turbidity value of the wash water during the pre-wash stage can characterize the content of insoluble stains remaining on the clothes after pre-washing.
[0119] The higher the turbidity value of the wash water in the pre-wash stage, the more insoluble stains remain, requiring a stronger wash in the main wash stage. Therefore, the turbidity level of the wash water in the pre-wash stage is positively correlated with the first coefficient; that is, the higher the turbidity level, the larger the first coefficient.
[0120] Specifically, different turbidity values, pH values, and turbidity changes correspond to different levels of coefficients, as shown in Table 4: Table 4. Coefficients for turbidity value, pH value, and turbidity change value corresponding to different levels.
[0121] For example, referring to Table 4, if the turbidity value of the washing water in the pre-wash stage is low, the first coefficient can be 0.8; if the turbidity value of the washing water in the pre-wash stage is medium, the first coefficient can be 0.87; if the turbidity value of the washing water in the pre-wash stage is high, the first coefficient can be 1.06.
[0122] S33, determine the second coefficient based on the pH value of the washing water during the pre-washing stage.
[0123] Specifically, the second coefficient is determined based on the pH level corresponding to the pH value of the washing water during the pre-washing stage.
[0124] The pH value of the washing water during the pre-wash stage can characterize the amount of water-soluble stains remaining on the clothes after pre-washing.
[0125] The greater the deviation of the pH value of the wash water in the pre-wash stage from the neutral range, the more water-soluble stains remain, requiring a stronger wash in the main wash stage. Therefore, the deviation of the pH value of the wash water in the pre-wash stage from the neutral range is positively correlated with the second coefficient.
[0126] For example, referring to Table 4, if the pH value of the washing water in the pre-wash stage is between 6.5 and 7.5, it belongs to the low grade, and the second coefficient can be taken as 0.93; if the pH value of the washing water in the pre-wash stage is between 5.5 and 6.5 or between 7.5 and 8.5, it belongs to the medium grade, and the second coefficient can be taken as 1.01; if the pH value of the washing water in the pre-wash stage is less than 5.5 or greater than 8.5, it belongs to the high grade, and the second coefficient can be taken as 0.864.
[0127] Alternatively, the value of the second coefficient can be determined based on the actual experimental results and pre-stored in the memory of the clothing processing equipment.
[0128] The pH value refers to the pH of the washing water in the pre-soaking stage versus the washing water in the pre-washing stage. It ranges from 0 to 14. A pH value less than 6.5 indicates acidic water, which will affect the saponification reaction, requiring increased washing intensity. A pH value between 6.5 and 7.5 indicates neutral water, representing an ideal state. A pH value greater than 7.5 indicates alkaline water, which may enhance detergency, but prolonged high alkalinity can damage fabrics.
[0129] S34, determine the third coefficient based on the turbidity change value.
[0130] Specifically, the third coefficient is determined based on the level of change corresponding to the change in turbidity.
[0131] Turbidity change values can characterize the washing effect of the pre-wash stage.
[0132] In other words, the greater the change in turbidity, the better the pre-wash effect, the less stains remain on the clothes, and the lower the washing intensity required in the main wash stage. Therefore, the level of change in turbidity is negatively correlated with the third coefficient; that is, the higher the level of change, the smaller the third coefficient.
[0133] For example, turbidity changes can be pre-classified into three levels: a change of less than 20 NTU is considered a low change level, 21 to 30 NTU is a medium change level, and a change of more than 30 NTU is a high change level. If the turbidity change is in the low change level, the third coefficient can be 0.96; if the turbidity change is in the medium change level, the third coefficient is 0.93; and if the turbidity change is in the high change level, the third coefficient is 0.8.
[0134] S35, determine the product of the first coefficient, the second coefficient and the third coefficient, which is the washing parameter correction coefficient.
[0135] The water quality information for the washing water includes its turbidity and pH value.
[0136] By multiplying the three coefficients to obtain the comprehensive correction coefficient, multiple factors such as the content and type of residual stains after pre-washing and the effect of pre-washing can be fully considered, making the correction coefficient more accurately reflect the washing intensity required in the main wash stage.
[0137] For example, the formula for calculating the washing parameter correction coefficient K can be defined as follows: K=fN current ×fY current ×f ΔN .
[0138] Among them, fN current The first coefficient is related to the turbidity value; fY curren t is the second coefficient, which is related to the pH value; f ΔN This is the third coefficient, which is related to the change in turbidity.
[0139] In this scheme, the first coefficient is determined by the turbidity value of the washing water in the pre-wash stage, the second coefficient is determined by the pH value of the washing water in the pre-wash stage, and the third coefficient is determined by the turbidity change value. This enables the determination of the actual washing effect and the residual dirt state of the clothes in the pre-wash stage, providing a basis for the dynamic adjustment of the subsequent main wash parameters.
[0140] Among them, the comprehensive correction coefficient is calculated by multiplication, which can realize the synergistic effect of various influencing factors. When multiple factors simultaneously indicate that the washing intensity needs to be increased or decreased, the correction coefficient will show the corresponding amplification or reduction effect, which is more in line with the actual washing needs.
[0141] This solution introduces the parameter of turbidity change, allowing for dynamic adjustment of the main wash parameters by appropriately increasing the main wash intensity when the pre-wash effect is poor, or appropriately decreasing the main wash intensity when the pre-wash effect is good. Simultaneously, by introducing the pH value parameter, it can take into account the residue of water-soluble stains, further improving the accuracy and applicability of the correction coefficient.
[0142] In addition, the correction coefficient calculation process takes over the initial water quality detection in the pre-soaking stage and the adaptive control in the pre-wash stage, providing key data support for the subsequent main wash stage. This forms a closed-loop control system from dirt detection and pre-wash control to main wash correction, enabling intelligent operation of the entire washing process. While ensuring washing effect, it also helps to reduce energy consumption in the washing process.
[0143] For example, if the test results after pre-washing are: the turbidity value of the washing water in the pre-washing stage is high, the pH value of the washing water in the pre-washing stage is medium, and the turbidity change is medium, then the washing parameter correction coefficient K = 1.0 × 0.9 × 0.9 = 0.81.
[0144] In an optional implementation of the washing control method for the aforementioned garment processing equipment, the washing parameters include at least the main wash duration, the main wash temperature, and the main wash speed. The set washing parameters for the main wash stage are corrected based on the washing parameter correction coefficient for the main wash stage, resulting in the corrected main wash parameters, including: The corrected main wash duration, temperature, and speed are obtained by multiplying the main wash duration, temperature, and speed by the washing parameter correction coefficients, respectively.
[0145] in this way, For example, if the main wash parameters are: main wash duration 65 min, main wash temperature 30℃, and main wash speed 1200 rpm, after coefficient adjustment: the corrected main wash duration = 65 × 0.81 ≈ 53 min; the corrected main wash temperature = 30 × 0.81 ≈ 24℃; and the corrected speed = 1200 × 0.81 ≈ 972 rpm.
[0146] The main wash duration mentioned here refers to the washing time during the main wash phase, excluding rinsing time and spin-drying time.
[0147] It's important to note that when adjusting the main wash temperature and spin speed, it's necessary to set both upper and lower limits to protect the fabric. This prevents the adjusted parameters from being too low and resulting in substandard washing performance. For example, the lower limit for the main wash temperature can be set to 15℃. When the adjusted temperature is below 15℃, the detergent's activity will significantly decrease, failing to effectively break down stains. In this case, the main wash temperature should be adjusted to 15℃. Similarly, the lower limit for the main wash spin speed can be set to 300 rpm. When the adjusted spin speed is below 300 rpm, the mechanical force is insufficient to remove residual stains from within the fabric fibers. In this case, the spin speed should be adjusted to 300 rpm.
[0148] The upper and lower limits of the main wash parameters corresponding to different fabric types can be pre-stored in the parameter database of the garment processing equipment. When adjusting the parameters, the corresponding upper and lower limit values are automatically retrieved according to the washing mode selected by the user. For example, the upper limit of the main wash temperature for silk fabrics can be set to 25℃, and the upper limit of the main wash speed can be set to 300 rpm; the upper limit of the main wash temperature for cotton and linen fabrics can be set to 60℃, and the upper limit of the main wash speed can be set to 1400 rpm.
[0149] When the corrected main wash parameters exceed the corresponding upper or lower limits, the garment processing equipment will automatically adjust the parameters to the corresponding upper or lower limits. For example, if a user selects wool fabric for washing, the initial main wash temperature is 30℃, and the main wash speed is 400 rpm. If the calculated correction factor is 1.2, the corrected main wash temperature will be 36℃, and the main wash speed will be 480 rpm, both exceeding the upper limits for wool fabric. In this case, the garment processing equipment will adjust the main wash temperature to 30℃, the main wash speed to 400 rpm, and appropriately extend the main wash time to compensate for the temperature and speed limitations, ensuring washing results.
[0150] The above solution enables synchronous and dynamic adjustment of the main wash parameters during the main wash phase. Simultaneously, it allows for matching the required chemical and mechanical action intensity during the main wash phase based on the actual residual dirt state after the pre-wash. Specifically, adjusting the main wash duration alters the contact time between the detergent and stains; adjusting the main wash temperature affects the detergent's activity and the stain's dissolution rate; and adjusting the main wash spin speed changes the magnitude of the mechanical force applied to the garments. These three factors work synergistically to ensure the optimal washing effect during the main wash phase.
[0151] In an optional embodiment of the washing control method for the aforementioned garment processing equipment, the pre-soaking stage includes at least: The washing tub is controlled to alternate between forward and reverse rotation a preset number of times, and then left to stand. After setting the settling time, obtain the water quality information of the washing water during the pre-soaking stage.
[0152] In this solution, the washing tub is controlled to alternate between forward and reverse rotation a preset number of times. Specifically, the tub rotates forward and reverse a preset number of times, with the two rotations alternating. This causes the clothes inside the tub to tumble and spread slightly, ensuring that all parts of the clothes are fully in contact with the washing water during the pre-soaking stage. This accelerates the dissolution of stains from the clothing surface and prevents uneven wetting caused by clothes piling up in certain areas.
[0153] Optionally, the preset number of attempts is two.
[0154] Alternatively, the preset number of cycles is N, where N≤10. By using fewer forward and reverse cycles, only gentle agitation is needed to satisfy the need for clothes to stretch and soak, avoiding tangling and pulling caused by frequent rotation, while also reducing equipment energy consumption and operating noise.
[0155] In addition, after the washing tub alternates between forward and reverse rotation a preset number of times, it stops rotating and remains still for a preset time. This allows dissolved stains on the clothes to spread evenly and completely in the washing water during the pre-soaking stage, avoiding deviations in test results caused by localized differences in water concentration and ensuring that the water quality information obtained subsequently accurately reflects the overall degree of soiling of the clothes.
[0156] Optionally, the preset settling time is 30 to 90 seconds. Within this range, it ensures that stains are fully and evenly dispersed without significantly increasing the total washing time due to excessive settling time, thus balancing detection accuracy and washing efficiency. For example, the preset settling time is 60 seconds.
[0157] Through the step-by-step control scheme of the pre-soaking stage, the clothes to be washed can be fully and evenly soaked with low water and low energy consumption. This allows various stains on the surface of the clothes and in the gaps between the fibers to be fully released and evenly diffused in the washing water during the pre-soaking stage. This provides a stable and reliable water sample basis for the accurate detection of water quality information in the subsequent pre-soaking stage, thereby ensuring the accuracy and consistency of the judgment results on the degree of dirtiness of the clothes based on water quality information.
[0158] Combination Figure 5 As shown, the determination of whether to proceed to the pre-wash stage or skip the pre-wash stage and proceed directly to the main wash stage is based on the water quality information of the washing water during the pre-soaking stage, including: S41, determine whether the turbidity value of the washing water in the pre-soaking stage is low and whether the pH value of the washing water in the pre-soaking stage is between the first pH threshold and the second pH threshold.
[0159] The water quality information for the washing water includes its turbidity and pH value.
[0160] In this scheme, turbidity values are pre-classified into multiple levels, including low, medium, and high levels. For example, when the turbidity detection device is an infrared turbidity sensor, a turbidity value less than 50 NTU is set as low level, 50 NTU to 200 NTU as medium level, and greater than 200 NTU as high level.
[0161] Simultaneously, a first acid-base threshold and a second acid-base threshold are preset, with the first acid-base threshold being less than the second acid-base threshold. For example, the first acid-base threshold is 6.5, and the second acid-base threshold is 7.5, meaning the neutral range is 6.5 to 7.5.
[0162] S42, if the turbidity of the washing water in the pre-soaking stage is low and the pH value of the washing water in the pre-soaking stage is between the first and second pH thresholds, then the main wash stage is determined to begin.
[0163] In other words, when the turbidity value is low and the pH value is in the neutral range, it indicates that the content of both insoluble and water-soluble stains on the clothes to be washed is low, and the overall soiling level of the clothes is light. Therefore, a good washing effect can be achieved directly in the main wash stage without needing a pre-wash stage. Proceeding directly to the main wash stage at this time can effectively shorten the total washing time and reduce the consumption of water, electricity, and detergent.
[0164] S43, if the turbidity value of the washing water in the pre-soaking stage is not low and / or the pH value of the washing water in the pre-soaking stage is not between the first pH threshold and the second pH threshold, then it is determined to enter the pre-washing stage.
[0165] When the turbidity value is medium or high, and the pH value deviates from the neutral range, it indicates that there are many insoluble or water-soluble stains on the clothes to be washed, and the overall soiling level of the clothes is relatively heavy. In other words, when the turbidity value is medium or high, and / or the pH value deviates from the neutral range, a pre-wash stage is required to pre-treat the clothes to remove and break down most of the stains in advance, in order to ensure the washing effect of the subsequent main wash stage.
[0166] This solution enables the simultaneous detection of both insoluble solid stains and water-soluble chemical stains, ensuring more accurate assessment of clothing soiling levels. It avoids overlooking water-soluble stains such as sweat and juice stains, which don't produce noticeable turbidity but affect washing performance, thus improving the accuracy of soiling determination. The solution skips the pre-wash stage only when both conditions are met, preventing missed detection of heavily soiled items due to errors in a single parameter. Furthermore, in non-low turbidity or non-neutral acid / alkaline conditions, the presence of any type of noticeable stain triggers the pre-wash stage, ensuring adequate pretreatment of the clothes. For heavily soiled clothes, pre-washing removes surface stains early, preventing the need for repeated washing due to insufficient washing intensity in the main wash stage, further reducing overall energy consumption.
[0167] Furthermore, the judgment results in this scheme not only determine whether to enter the pre-wash stage, but also the output initial turbidity level and acid-base level data can serve as the data basis for adaptive adjustment of pre-wash parameters and / or dynamic correction of main wash parameters.
[0168] In an optional embodiment of the washing control method for the aforementioned garment processing equipment, the washing control method further includes: If it is determined to skip the pre-wash stage and proceed directly to the main wash stage, the washing will run according to the washing parameters set for the main wash stage corresponding to the user-defined washing mode.
[0169] Thus, when the laundry is determined to be lightly soiled and does not require a pre-wash stage, the main wash can be performed directly using the set washing parameters for the main wash stage corresponding to the user-selected washing mode, without the need for additional parameter correction or adaptive adjustment. The control logic is simple and efficient. This eliminates redundant pre-wash water intake, washing, and drainage steps, saving water, reducing energy consumption, and minimizing detergent consumption, thereby shortening the overall washing time.
[0170] Secondly, this application provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, it implements the washing control method as described above.
[0171] Thirdly, this application provides a garment processing device, including a control device or the aforementioned electronic device, wherein the control device is configured with a control program for the washing control method of the garment processing device as described above.
[0172] In this application, after the user puts the clothes to be washed into the washing tub, in order to better understand the control logic of the clothes handling device during washing in the embodiments of this application, combined with Figure 5 To elaborate further: Step S51: Obtain the washing mode and stain type selected by the user; determine the set washing parameters of the main wash program based on the washing mode.
[0173] Step S52: Obtain the initial weight of the clothes to be washed.
[0174] Step S53: Enter the pre-soaking stage and obtain the water quality information of the washing water in the pre-soaking stage. The pre-soaking stage uses a lower amount of washing water than the pre-washing stage to wet the clothes to be washed in the tub, so that the stains on the clothes to be washed can be dissolved in the washing water in the pre-soaking stage.
[0175] Step S54: Determine whether the turbidity value of the washing water in the pre-soaking stage is low and whether the pH value of the washing water in the pre-soaking stage is between the first pH threshold and the second pH threshold.
[0176] If so, proceed directly to the main wash stage and run according to the set washing parameters in step S55.
[0177] Step S56: If not, proceed to the pre-wash stage.
[0178] Step S57: Determine the correction coefficient for the washing parameters in the main wash stage based on the water quality information of the washing water in the pre-soaking stage and the washing water in the pre-washing stage.
[0179] Step S58: Correct the set washing parameters of the main wash stage according to the washing parameter correction coefficient of the main wash stage to obtain the corrected main wash washing parameters, and run the main wash stage according to the corrected main wash washing parameters.
[0180] If the system enters the pre-wash stage, the user's selected washing mode, stain type, initial weight, pH value and turbidity value of the washing water in the pre-soaking stage are input into the pre-trained prediction model to output pre-wash parameters, and the system enters the pre-wash stage according to the pre-wash parameters.
[0181] After the pre-wash stage is completed, obtain the water quality information of the washing water used in the pre-wash stage.
[0182] Furthermore, based on the water quality information of the washing water in the pre-wash stage and the washing water in the pre-soak stage, correction coefficients for the main wash parameters are determined. Specifically, the turbidity change value is determined based on the difference between the turbidity values of the washing water in the pre-wash stage and the washing water in the pre-soak stage; a first coefficient is determined based on the turbidity level corresponding to the turbidity value of the washing water in the pre-wash stage; a second coefficient is determined based on the pH level corresponding to the pH value of the washing water in the pre-wash stage; and a third coefficient is determined based on the change level corresponding to the turbidity change value. The product of the first, second, and third coefficients is determined as the washing parameter correction coefficient.
[0183] This solution eliminates the need for users to manually set washing parameters. The garment processing equipment initially determines the main wash parameters based on the user-selected washing mode. The garments are then pre-soaked to determine whether to proceed directly to the main wash stage based on the water quality information from the pre-soaking stage. If proceeding directly to the main wash stage, the washing is performed according to the main wash parameters. If pre-soaking is performed first, the user-selected washing mode, stain type, initial weight of the garments, pH value of the pre-soaking stage water, and turbidity value of the pre-soaking stage water are input into a pre-trained prediction model to output pre-wash parameters. Combining the water quality information from the pre-soaking and pre-washing stages, correction coefficients for the main wash parameters are determined. This approach improves garment cleaning efficiency while avoiding damage to garment fibers from over-washing, thus enhancing both washing performance and fabric protection while reducing energy consumption.
