[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] The washing equipment, control method and apparatus, and storage medium of the present invention are described below with reference to the accompanying drawings.

[0038] First, it should be noted that the washing equipment's operation process includes multiple washing stages, which may include a pre-wash stage, a main wash stage, a rinsing stage, and a drying stage. The pre-wash stage is a rough rinse of the clothes to be washed, mainly to wash away easily rinsed contaminants. The main wash stage and the rinsing stage are for a more detailed cleaning of the clothes to be washed. The drying stage is for drying the washed clothes.

[0039] Figure 1 This is a flowchart of a control method for a washing device according to an embodiment of the present invention. The control method includes the following steps:

[0040] S10, Obtain washing parameters of the washing equipment in at least one washing stage.

[0041] Specifically, the washing equipment includes components such as a washing chamber, a filter screen, a centrifugal motor, and a washing pump. During operation, washing water is first added to the washing chamber. The washing pump controls the circulation of the washing water to rinse the items to be washed. The filter screen filters the washing water in the washing chamber, preventing food residue and other objects from affecting the washing pump and thus its operation, while also ensuring the cleanliness of the washing water. The centrifugal motor drives the filter screen to rotate, preventing clogging. During operation, washing parameters can be acquired, including changes in the centrifugal motor current, the turbidity of the washing water, and the total dissolved solids. The total dissolved solids represent the total amount of all inorganic and organic matter dissolved in the washing water.

[0042] During the washing process of the washing equipment, washing parameters can be acquired through sensors and other detection devices. Each washing parameter can be acquired through different sensors. For washing parameters that can be transformed, one washing parameter can be acquired and then transformed and calculated to obtain other washing parameters. The specific acquisition method is not limited here. This embodiment can be applied to each washing stage of the washing equipment, enabling precise control of the washing sequence and / or detergent dosage at each stage.

[0043] S20, determine the comprehensive washing index of the washing equipment based on the washing parameters.

[0044] Specifically, after obtaining the washing parameters, the current comprehensive washing index of the washing equipment can be determined based on these parameters. It should be noted that the comprehensive washing index can be used to represent the washing effect of the clothes to be washed.

[0045] In some embodiments of the present invention, the change in current of the centrifugal motor, the turbidity of the washing water, and the total amount of dissolved solids are input into a preset washing index model for fusion processing to determine a comprehensive washing index.

[0046] Specifically, see Figure 2 After obtaining the current change of the centrifugal motor, the turbidity of the washing water, and the total dissolved solids, data preprocessing can be performed. This preprocessing can filter out obviously erroneous data. Specifically, a data range can be configured for each washing parameter. If the obtained washing parameter exceeds the corresponding data range, it can be determined that the parameter is erroneous and thus filtered out. It should be noted that the data range in this embodiment can be updated at preset intervals to ensure accurate preprocessing of the washing parameters. Since the current change, turbidity, and total dissolved solids are all in different units, in order to fuse these parameters, the preprocessing in this embodiment can also include data normalization to prepare for subsequent fusion processing.

[0047] After data preprocessing is completed, features can be extracted from the preprocessed data, and subsequent data fusion processing can be performed based on the extracted features. Specifically, corresponding weights can be assigned to each feature, and then all features can be weighted and averaged to complete the data fusion and obtain the comprehensive washing index of the washing equipment.

[0048] In some embodiments, the comprehensive washing index can be determined using the following preset washing index model: W = α*I + β*C + γ*D, where W represents the comprehensive washing index, I represents the change in current of the centrifugal motor, C represents the turbidity of the washing water, D represents the total dissolved solids, and α, β, and γ are model parameters, which in the above embodiment are the weights assigned to each washing parameter. The specific weight allocation in this embodiment can be determined based on experimental data; the greater the impact on the washing effect, the greater the weight, and vice versa.

[0049] S30, adjust the washing sequence and / or detergent dosage of the washing equipment according to the comprehensive washing index.

[0050] Specifically, after determining the comprehensive washing index, the washing effect of the clothes to be washed can be obtained. Then, the washing sequence and / or detergent dosage can be adjusted according to the clothes to be washed to save washing resources and ensure washing effect. The washing sequence can include the washing actions of the washing equipment, washing duration, washing intensity, etc. Furthermore, in this embodiment, the initial values ​​of the washing sequence and detergent dosage can be directly used as preset initial values. The detergent volume can also be directly determined based on the total dissolved solids in the washing water. In subsequent adjustments to the detergent dosage, a certain amount of detergent can be added directly based on the comprehensive washing index; the specific adjustment method is not limited here.

[0051] In some embodiments of the present invention, such as Figure 3 As shown, the control method for the washing equipment also includes:

[0052] S301 updates the comprehensive washing index every first preset time interval.

[0053] S302, Adjust the washing sequence and / or detergent dosage of the washing equipment according to the updated comprehensive washing index.

[0054] Specifically, during the washing process, the washing parameters of the washing equipment can be re-acquired every first preset time interval. The comprehensive washing index is then updated based on the newly acquired washing parameters. The updated comprehensive washing index can further determine the latest washing effect of the current items to be washed. Based on the latest washing effect, it can be determined how to adjust the washing sequence and / or detergent dosage of the washing equipment, such as increasing the washing time by two minutes, increasing the speed of the centrifugal motor by 100 revolutions per minute, or increasing the detergent dosage by 0.05 ml.

[0055] In some embodiments of the present invention, adjusting the washing sequence of the washing equipment according to the comprehensive washing index includes: inputting the comprehensive washing index into a preset washing duration prediction model to determine the washing duration.

[0056] Specifically, after calculating the comprehensive washing index of the washing equipment, the washing effect of the current laundry can be determined. If the washing effect is poor, the washing time can be increased to improve it; conversely, if the washing effect is good, the washing time can be reduced to save resources. Furthermore, in some examples, the washing time can be determined using the following preset washing time prediction model: T = a * W^b + c, where T represents the washing time, W represents the comprehensive washing index, and a, b, and c are model parameters.

[0057] In some embodiments of the present invention, the control method further includes: inputting washing parameters into a preset detergent dosage prediction model to determine the detergent dosage of the washing equipment.

[0058] Specifically, the amount of detergent needed can be determined by the washing parameters, specifically by the total dissolved solids in the wash water. A higher total dissolved solids in the wash water indicates a higher level of soiling in the garment, requiring more detergent to ensure effective washing. Conversely, a lower total dissolved solids indicates a lower level of soiling, requiring less detergent to conserve washing resources. More specifically, the detergent dosage can be determined using the following preset detergent dosage prediction model: A = k * (D_max - D) * V / 1000, where A represents the detergent dosage, D represents the total dissolved solids, D_max represents the preset total dissolved solids, V represents the preset wash water, and k represents the model parameters.

[0059] In some embodiments of the present invention, such as Figure 4 As shown, adjusting the washing sequence of the washing equipment according to the comprehensive washing index also includes the following steps:

[0060] S401, when the comprehensive washing index is greater than the first preset index, the washing intensity is determined to be the first preset intensity.

[0061] S402, when the comprehensive washing index is less than or equal to the first preset index and greater than the second preset index, the washing intensity is determined to be the second preset intensity, and the second preset intensity is less than the first preset intensity.

[0062] S403, when the comprehensive washing index is less than or equal to the second preset index, the washing intensity is determined to be the third preset intensity, and the third preset intensity is less than the second preset intensity.

[0063] Specifically, this embodiment can also determine the washing intensity of the main wash stage based on the comprehensive washing index. Specifically, the washing index can be divided into three intervals using a first preset index and a second preset index. After obtaining the comprehensive washing index, the range of the comprehensive washing index is further determined. If the comprehensive washing index is greater than the first preset index, it indicates that the current level of dirt is very high, so the washing intensity can be determined as a relatively strong first preset intensity. If the comprehensive washing index is less than or equal to the first preset index but greater than the second preset index, it indicates that the current level of dirt is moderate, so the washing intensity can be determined as a medium second preset intensity. If the comprehensive washing index is less than the second preset index, it indicates that the current level of dirt is very low, so the washing intensity can be determined as a weak third preset intensity.

[0064] In some embodiments of the present invention, in order to further improve the washing effect and save washing materials, the control method further includes: acquiring washing data of the washing equipment and the washing effect of the clothes to be washed; and updating the model parameters in the preset washing index model, the preset washing time prediction model, and the preset detergent dosage prediction model according to the washing data and the washing effect.

[0065] Specifically, in this embodiment, after washing is completed, the washing effect of the clothes to be washed and the washing data of the washing equipment can be obtained. This washing data may include consumable quantities, such as electricity consumption, water consumption, and detergent dosage. Then, based on the washing data and washing effect, more suitable model parameters are determined. It is understood that under the determined model parameters, the optimal balance between the washing equipment's consumables and the washing effect of the clothes to be washed is achieved; that is, while meeting the washing effect requirements, the consumables are minimized, reducing the operating cost of the washing equipment.

[0066] In one embodiment of the present invention, the washing stage includes a pre-wash stage, a main wash stage, and a rinsing stage, such as... Figure 5 As shown, the control method for the washing equipment also includes the following steps:

[0067] S501, Obtain the washing parameters of the washing equipment during the initial washing stage.

[0068] Specifically, after the washing equipment is turned on, initialization can be performed first, recording the initial values ​​of each sensor and setting the relevant parameters of the model used for subsequent calculations. It's understandable that these parameters may differ depending on the degree of soiling of the laundry. After initialization, the washing equipment enters the initial wash stage, during which the centrifugal motor, washing pump, and filter can be started. The centrifugal motor is a brushless DC motor, ensuring high efficiency and low noise. This brushless DC motor has a rated voltage of 24 volts, a power of 200 watts, and a maximum speed of 3000 rpm. The motor driver uses the FOC (Field Oriented Control) algorithm to achieve precise speed control. It should be noted that different washing parameters require different sensors. For example, the turbidity of the washing water can be obtained using a turbidity sensor. This turbidity sensor can be a photoelectric turbidity sensor with a measurement range of 0-1000 NTU, an accuracy of ±2%, and a sampling frequency of 1 Hz. A digital filtering algorithm is used to remove acquisition noise. Alternatively, the total dissolved solids (TDS) sensor can be used to obtain the total amount of dissolved solids in the washing water. Specifically, this TDS sensor is a conductivity type with a measurement range of 0-1000 ppm, an accuracy of ±2%, a sampling frequency of 1 Hz, and an automatic temperature compensation function.

[0069] S502, determine the washing sequence and / or detergent dosage of the washing equipment in the main washing stage based on the washing parameters of the initial washing stage.

[0070] Specifically, after determining the washing parameters for the initial wash stage, the washing information for the main wash stage can be calculated based on these parameters, namely the specific washing time, detergent dosage, and washing intensity. It should be noted that different calculation models can be used for different washing information. Of course, it can also be obtained directly by looking up a table. No specific calculation method is limited here.

[0071] S503: During the main wash phase, the current washing parameters of the washing equipment are acquired every second preset time interval.

[0072] S504, Adjust the washing sequence and / or detergent dosage during the main wash stage according to the current washing parameters.

[0073] Specifically, after the washing equipment enters the main washing stage, the centrifugal motor, washing pump, and other devices continue to operate. To further improve the washing effect, this embodiment also acquires the current washing parameters of the washing equipment every second preset time interval. Using these current washing parameters, washing information is continuously calculated to update the washing time and washing intensity, thereby enabling timely adjustment of the washing information of the clothes to be washed and ensuring thorough washing. Optionally, the second preset time interval is 2 minutes, 3 minutes, 4 minutes, etc., and the first preset time interval in the above embodiment can be equal to the second preset time interval.

[0074] In some embodiments of the present invention, such as Figure 6 As shown, the control method for the washing equipment also includes:

[0075] S601, during the rinsing stage, obtain the total amount of dissolved solids in the wash water.

[0076] S602, if the total amount of dissolved solids is less than the preset total amount of dissolved solids, control the washing equipment to enter the drying stage.

[0077] Specifically, after the main wash stage, the washing equipment enters the rinsing stage. During the rinsing stage, the washing pump continues to circulate and rinse the laundry. During this rinsing process, the washing equipment also continues to measure the total dissolved solids in the wash water. The total dissolved solids are then used to determine whether rinsing is complete; if so, the washing equipment can proceed to the drying stage. This embodiment sets a preset total dissolved solids value. The measured total dissolved solids value is compared with this preset value to determine if the laundry has been thoroughly rinsed. When the total dissolved solids value is less than the preset value, the laundry is considered rinsed completely and can proceed to the drying stage for drying.

[0078] In one specific embodiment of the present invention, such as Figure 7 As shown, the washing equipment is first initialized, including determining model parameters and preset values ​​for comparison. After initialization, the washing equipment can enter the pre-wash stage. The centrifugal motor speed during the pre-wash stage can be 2000 rpm, and the pre-wash duration can be set to 3-5 minutes. During the pre-wash stage, washing parameters are collected, and the collected current changes, turbidity, and total dissolved solids are combined to obtain a comprehensive washing index. If the comprehensive washing index is greater than 0.8, a strong washing strategy is used; if the comprehensive washing index is less than or equal to 0.8 but greater than 0.5, a standard washing strategy is used; if the comprehensive washing index is less than or equal to 0.5, a mild washing strategy is used. After entering the main wash stage, the washing equipment executes the washing program according to the washing intensity. The strong wash corresponds to a washing time of 25 minutes and a centrifugal motor speed of 2500 rpm; the standard wash corresponds to a washing time of 20 minutes and a centrifugal motor speed of 2200 rpm; and the mild wash corresponds to a washing time of 15 minutes and a centrifugal motor speed of 2000 rpm. During the main wash phase, the washing effect is monitored every 3 minutes to recalculate the overall washing index. The overall washing index is used to determine whether the main wash phase has ended; if not, the washing data is adjusted. Specifically, if the overall washing index is detected to be less than 0.3, the main wash phase ends; otherwise, the washing time is increased by 2 minutes, the centrifugal motor speed is increased by 100 rpm, and the detergent dosage is increased by 0.05 ml, then the washing program continues. After the main wash phase, two rinsing phases are performed, each lasting two minutes, followed by a drying phase that lasts 15 minutes. Figure 8 In this specific embodiment, the current of the centrifugal motor, the turbidity of the washing water, and the total amount of dissolved solids in the washing water change with the washing time. In the pre-wash stage, the current, turbidity, and total amount of dissolved solids all rise continuously to a stable state before entering the main wash stage. In the main wash stage, the current of the centrifugal motor will decrease as the filter removes contaminants (such as food residue), while the turbidity and total amount of dissolved solids in the washing water will gradually increase due to the improved washing effect. After the main wash stage ends and the rinsing stage begins, the washing water and contaminants will be discharged, and the current, turbidity, and total amount of dissolved solids will all decrease until the rinsing stage also ends.

[0079] It should be noted that the power pump used for dispensing detergent in this embodiment can be a peristaltic pump, which can achieve precise detergent dispensing with an accuracy of 0.1ml. The storage tank has a capacity of 500ml, which is sufficient for 30-50 washes. The washing pump can be a high-efficiency variable frequency circulating pump with a rated power of 100W and a maximum flow rate of 20L / min. The water flow intensity can be precisely adjusted through variable frequency control to adapt to different washing needs.

[0080] More specifically, the present invention can also be used in different usage scenarios. The following description will take a standard household daily use scenario and a heavily polluted scenario as examples.

[0081] In a standard household daily use scenario, the parameters are first initialized. The weights of each parameter in the comprehensive washing index are set to α = 0.4, β = 0.3, and γ = 0.3. The model parameters in the washing time prediction model can be determined as a = 5, b = 0.5, and c = 10, and the detergent dosage ratio coefficient k = 0.2. After initialization, the washing equipment enters the washing program. The user first puts in 6 place settings, including lightly to moderately soiled plates, bowls, and tableware. The washing equipment starts, and the initial values ​​are recorded: centrifugal motor no-load current: 0.8A, initial turbidity of washing water: 5 NTU, and initial TDS of washing water: 100 ppm. Entering the pre-wash stage (3 minutes), in this preset stage, the centrifugal motor current rises to 1.2A, the turbidity of the washing water rises to 50 NTU, and the TDS of the washing water rises to 150 ppm. The comprehensive washing index is calculated as: I = 0.4 * (1.2 - 0.8) / 0.4 + 0.3 * 50 / 1000 + 0.3 * 150 / 1000 = 0.595. Entering the main wash stage, the predicted washing time is: T = 5 * 0.595^0.5 + 10 ≈ 13.9 minutes. The washing equipment can be set to a main wash time of 14 minutes. The initial detergent dosage is calculated as: A = 0.2 * (300 - 150) * 5 / 1000 = 0.15 ml. During the main wash stage, the washing intensity and remaining time are dynamically adjusted every 30 seconds after reassessment. In the rinsing stage, the washing equipment performs two rinsing cycles, each lasting two minutes, ultimately reducing the TDS of the wash water to 120 ppm. Then, the drying stage begins, lasting 15 minutes. Analysis of the experimental data confirms that the washing method of this invention achieves a total washing time of only 36 minutes, saving 20% ​​compared to traditional fixed programs; water consumption is only 9.5L, saving 2.5L compared to traditional programs; electricity consumption is only 0.65kWh, saving 0.15kWh compared to traditional programs; and detergent usage is only 12ml, saving 3ml compared to traditional programs.

[0082] In a heavily polluted scenario, the parameters are first initialized. The weights of each parameter in the comprehensive washing index can be set to α = 0.4, β = 0.3, and γ = 0.3. The model parameters in the washing time prediction model can be determined as a = 5, b = 0.5, and c = 10, with the detergent dosage ratio coefficient k = 0.2. After initialization, the washing equipment enters the washing program. The user first places four sets of tableware, including a greasy frying pan, a baking pan, and tableware with dry, hard food residue. The washing equipment starts, and the initial values ​​are recorded: centrifugal motor no-load current: 0.8A, initial turbidity of the washing water: 10 NTU, and initial TDS of the washing water: 120 ppm. Entering the pre-wash stage (5 minutes), in this preset stage, the current of the centrifugal motor rises to 1.8A, the turbidity of the washing water rises to 180 NTU, and the TDS of the washing water rises to 250 ppm. The comprehensive washing index is calculated as follows: I = 0.4 * (1.8 - 0.8) / 0.4 + 0.3 * 180 / 1000 + 0.3 * 250 / 1000 = 1.225. The system then enters the main wash stage. The predicted wash time for this stage is: T = 5 * 1.225^0.5 + 10 ≈ 15.5 minutes. The washing machine can be set to a main wash time of 16 minutes. The initial detergent dosage is calculated as: A = 0.2 * (400 - 250) * 6 / 1000 = 0.18 ml. During the main wash stage, the system reassesses every 30 seconds, dynamically adjusting the wash intensity and remaining time. If, at the preset time (e.g., the 8th minute), the turbidity and TDS decrease slowly, the wash time can be increased by 2 minutes. Next, the system enters the rinsing stage, performing three rinsing cycles of 2.5 minutes each, ultimately reducing the TDS of the wash water to 130 ppm. Finally, the system enters the drying stage, continuing to dry for 20 minutes. Analysis of the experimental data shows that the washing method of this invention has a total washing time of only 54 minutes, which is 15% less than the traditional fixed program; water consumption is only 13L, which is 3L less than the traditional program; electricity consumption is only 0.95kWh, which is 0.2kWh less than the traditional program; and detergent consumption is only 18ml, which is 2ml less than the traditional program.

[0083] Optionally, the degree of soiling of the tableware can be determined using a camera combined with image recognition technology, while the cleaning ability can be improved by adding ultrasonic cleaning equipment. Of course, due to the rapid development of the Internet of Things, the washing equipment can also be connected to a mobile terminal, allowing users to control the equipment via their mobile devices.

[0084] In summary, the control method of the washing equipment in this embodiment of the invention can update the washing intensity and washing duration in real time according to the washing parameters, so that the washing equipment can clean the clothes to be washed more accurately, ensuring the washing effect while avoiding the waste of washing resources.
