[0012] In some embodiments of the present invention, both the first operating information and the second operating information include current parameters and / or torque parameters.

[0013] In some embodiments of the present invention, the weight of the pollutant is determined according to the following model: W = k * (T - T0), where W represents the weight of the pollutant, T represents the first operating information, T0 represents the baseline operating information of the centrifugal motor when it is unloaded, and k represents the model parameter.

[0034] 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.

[0035] The following description, with reference to the accompanying drawings, describes the washing equipment, washing time determination method and apparatus, and storage medium of embodiments of the present invention.

[0036] Before introducing the washing time determination method of the washing device of the present invention, the washing device of the present invention will be described accordingly, such as... Figure 1 As shown, Figure 1This is a schematic diagram of a washing device according to one embodiment of the present invention. Taking a dishwasher as an example, the washing device includes a washing chamber 104 and a centrifugal motor 102, as well as a washing pump 101, a filter screen 103, a drain pump 105, a spray arm 106, and a solenoid valve 107. When the dishwasher starts working, an external water supply device first supplies washing water to the washing chamber 104. The washing pump 101 controls the circulation of the washing water in the washing chamber 104, the filter screen 103, and the spray arm 106. That is, after the washing water washes the clothes in the washing chamber 104, it can be filtered through the filter screen 103, and then pumped by the washing pump 101 to the spray arm 106. The spray arm 106 pressurizes the water and sprays it again to clean the clothes in the washing chamber 104. During the washing process, the centrifugal motor 102 can control the rotation of the filter screen 103 to improve the filtration effect of the filter screen 103; after the washing is completed, the washing water in the washing chamber 104 can be drained through the solenoid valve 107 and the drain pump 105. It should be noted that in this embodiment, the filter 103 can be a cylindrical stainless steel filter with a diameter of 25 cm and a thickness of 0.5 cm, and the diameter of the mesh can be 0.5 mm. In some examples, the filter can adopt a multi-layer structure, with the height of the multiple layers stacked up to 20 cm. The outer layer is a coarse filter with a mesh diameter of 1-2 mm, used to filter large food residues; the middle layer is a fine filter with a mesh diameter of 0.1-0.5 mm, used to filter small particulate pollutants; and the inner layer is an ultra-fine filter with a mesh diameter of 0.01-0.05 mm, used to filter tiny impurities. In addition, the surface of the filter can also be coated with a special hydrophobic nano-coating to improve the self-cleaning ability of the filter. The centrifugal motor 102 can be a brushless DC motor with a rated voltage of 12 volts, a rated power of 20 watts, and a maximum speed of 3000 rpm. The brushless design can improve reliability and service life.

[0037] Figure 2 This is a flowchart of a method for determining the washing time of a washing device in one embodiment of the present invention.

[0038] Based on the aforementioned washing equipment, this invention proposes a method for determining the washing time of the washing equipment, such as... Figure 2 As shown, the method for determining the washing time of this washing equipment includes the following steps:

[0039] S10: When the washing equipment is in the pre-washing stage, the first operating information of the centrifugal motor is obtained.

[0040] Specifically, the washing program of the washing equipment may include a pre-wash stage, a main wash stage, a rinsing stage, and a drying stage. The pre-wash stage involves a rough rinse of the clothes to be washed, primarily to remove easily rinseable contaminants. The main wash stage uses detergent to clean the clothes more thoroughly. The rinsing stage removes any detergent residue from the clothes. The drying stage dries the washed clothes. During the pre-wash stage, contaminants such as oil and food residue on the clothes are rinsed into the filter. Since the centrifugal motor controls the rotation of the filter, the accumulation of contaminants on the filter affects the operating parameters of the centrifugal motor. In this embodiment, information about the contaminants can be indirectly obtained by acquiring the operating parameters of the centrifugal motor. In some embodiments, the first operating information of the centrifugal motor may be the current parameters and / or torque parameters of the centrifugal motor. Therefore, this embodiment can also set a sensor to acquire the current parameters and / or torque parameters of the centrifugal motor. Taking the current parameter as an example, this embodiment can install a high-precision current sensor on the centrifugal motor to detect the current parameter. The measurement range of this current sensor can be 0-10 amperes, the measurement accuracy can be ±0.1 amperes, the sampling frequency can be 100 Hz, and the current detected by the current sensor can be filtered by a digital filtering algorithm to remove noise signals. There is a certain relationship between the torque parameter and the current parameter. The torque can be calculated from the current parameter. Of course, another sensor can also be set to detect the operating torque of the centrifugal motor. The specific acquisition method is not limited here.

[0041] S20, determine the weight of contaminants in the washing chamber based on the first operating information.

[0042] Specifically, after obtaining the first operating information of the centrifugal motor, the first operating information can be input into the calculation model to calculate the weight of contaminants in the washing chamber. Specifically, the weight of contaminants can be determined according to the following model: W = k * (T - T0), where W represents the weight of contaminants, T represents the first operating information, T0 represents the baseline operating information of the centrifugal motor when it is unloaded, and k represents the model parameter. It should be noted that the baseline operating information in this embodiment can be pre-stored in the information storage of the washing equipment, and if the first operating information represents different parameters, the corresponding value of the model parameter k can also be different.

[0043] More specifically, see Figure 3 As shown, taking the first operating information as the current as an example, the reference operating information T0 can be 0.85 amperes. By fitting the relationship between the current and the weight of the pollutants based on historical data or experimental data, we can obtain W = 882.35 * (T - 0.85).

[0044] S30, based on the first operating information and the weight of the contaminants, determines the predicted duration of the main wash phase of the washing equipment.

[0045] Specifically, after obtaining the first operating information and the weight of the contaminants, the predicted duration of the main wash stage of the washing equipment can be further determined using this information. It is understood that when the weight of the contaminants is relatively low, the predicted duration of the main wash stage will be relatively short; when the weight of the contaminants is relatively high, the predicted duration will be relatively long to ensure that the laundry is thoroughly cleaned. In some embodiments, the predicted duration of the main wash stage is determined according to the following model: T_main = a*W + b*T + c, where T_main represents the predicted duration of the main wash stage, W represents the weight of the contaminants, T represents the first operating information, and a, b, and c represent model parameters. It should be noted that if the first operating information represents different parameters, the corresponding values ​​of the model parameters a, b, and c can also be different.

[0046] In some embodiments of the present invention, the washing duration determination method further includes: when the fluctuation range of the first operating information is less than a first preset range and the washing equipment is in the pre-wash stage for a duration of the first preset duration, controlling the pre-wash stage to end and entering the main wash stage.

[0047] Specifically, during the pre-wash stage of the washing equipment, the first operating information fluctuates due to the accumulation of contaminants. This embodiment continuously acquires the first operating information and determines whether significant fluctuations occur. When the contaminants have been rinsed and accumulated on the filter, the first operating information tends to stabilize. Therefore, this embodiment can use the stability of the first operating information to determine whether the washing equipment has completed the pre-wash stage. A first preset duration can also be set, which can be determined based on historical operating data or experimental data of the washing equipment; for example, the first preset duration can be set to eight minutes. When the fluctuation range of the first operating information is less than the first preset range, and the pre-wash stage duration reaches the first preset duration, it can be determined that the washing equipment has completed the pre-wash stage, and the washing program can be changed to enter the main wash stage, where detergent can be added, etc. It should be noted that the first preset range in this embodiment can also be determined based on historical operating parameters or experimental data of the washing equipment; the specific determination method is not specifically limited here.

[0048] In some embodiments of the present invention, such as Figure 4 As shown, the method for determining washing time also includes:

[0049] S401: When the washing equipment is in the main washing stage, the second operating information of the centrifugal motor is obtained.

[0050] S402, when the fluctuation range of the second operating information is less than the second preset range and the duration of the washing equipment in the main washing stage reaches the predicted duration of the main washing stage, the main washing stage is controlled to end.

[0051] Specifically, during the main wash phase, the detergent can clean some of the contaminants, reducing their weight. Consequently, the secondary operating information of the washing equipment will decrease after the main wash phase has been running for a period of time. For example... Figure 5 As shown in the diagram. In this embodiment, the operating information of the centrifugal motor is still acquired during the main wash stage to obtain the second operating information. When the fluctuation range of the second operating information is relatively small, it indicates that the contaminants have been almost completely washed away. At this point, it is determined whether the washing time of the washing equipment in the main wash stage has reached the predicted time of the main wash stage. If it has, the main wash stage can be ended, and the subsequent rinsing and drying stages can proceed. Optionally, the predicted time of the main wash stage in this embodiment can be 8-34 minutes, and the duration of the rinsing and drying stages can be 34-50 minutes. During the rinsing and drying stages, the operating parameters of the centrifugal motor will gradually return to the initial level. In addition, the values ​​of the first preset range and the second preset range in the above embodiment can be ±0.02 amperes.

[0052] In some examples, the second operating information is the same as the first operating information, and may also represent the current parameters and / or torque parameters of the centrifugal motor. For details, please refer to the description of the first operating information above, which will not be repeated here.

[0053] In some embodiments of the present invention, such as Figure 6 As shown, the method of the present invention further includes the following steps:

[0054] S601, acquire washing data from the washing equipment and the washing effect of the clothes to be washed.

[0055] S602 optimizes the model parameters based on washing data and washing results.

[0056] Specifically, the model parameters involved in the above calculation model can be updated in this embodiment. This can be done based on the washing data from the washing equipment and the washing effect of the clothes to be washed. After washing, the washing effect of the clothes and the washing data from the washing equipment can be obtained. This washing data may include consumable quantities, such as electricity consumption, water consumption, and detergent dosage. The washing effect indicates the degree of soiling of the clothes before and after washing. More suitable model parameters are determined by fitting the washing data and washing effect. It is understood that under the determined model parameters, the washing equipment achieves the best balance between consumables and washing effect; that is, while meeting the washing effect requirements, consumables are minimized, thereby reducing the operating cost of the washing equipment.

[0057] In some embodiments of the present invention, such as Figure 7 As shown, the method of the present invention further includes the following steps:

[0058] S701, the degree of pollution is determined based on the weight of the pollutants.

[0059] S702 adjusts the temperature of the washing water and the spray intensity of the spray arm according to the degree of pollution.

[0060] Specifically, the spray arm is used to spray washing water into the washing chamber. Both the temperature of the washing water and the spray intensity of the spray arm can affect the washing effect on the clothes to be washed. To further improve the washing effect and avoid resource waste, this embodiment can also determine the degree of contamination of the clothes to be washed based on the weight of the contaminants, and then determine the temperature of the washing water and the spray intensity of the spray arm based on the degree of contamination. It should be noted that both the temperature of the washing water and the spray intensity of the spray arm are positively correlated with the degree of contamination; that is, the higher the degree of contamination, the higher the temperature of the washing water and the greater the spray intensity of the spray arm. Of course, the temperature of the washing water and the spray intensity of the spray arm are limited by corresponding temperature and intensity ranges. The specific ranges can be determined based on the materials used in the washing equipment, historical operating data, etc., and are not limited here.

[0061] In summary, such as Figure 8 As shown, when the washing program starts, an initialization program is first executed to initialize the parameters in the calculation model. After initialization, the pre-wash stage begins. The current signal of the centrifugal motor is detected, and it is determined whether the current signal is stable. This current signal is the first operating signal in the above embodiment. If the current signal is stable, the weight of the contaminants and the predicted duration of the main wash stage are estimated based on the current signal. Then, the main wash stage begins. In the main wash stage, the current signal of the centrifugal motor is detected again, and it is determined whether the current signal is stable. This current signal is the second operating signal in the above embodiment. If it is stable, the main wash stage begins.

[0062] In summary, the washing time determination method of the washing equipment in the embodiments of the present invention can determine the washing time according to the degree of dirtiness of the clothes to be washed, ensuring the washing effect, while saving washing resources and reducing washing costs.

[0063] Furthermore, the present invention proposes a computer-readable storage medium storing a washing duration determination program for a washing device, wherein when the washing duration determination program is executed by a processor, the washing duration determination method for the washing device described in any of the above embodiments is implemented.

[0064] The computer-readable storage medium of this invention executes a washing duration determination program for a washing device stored thereon via a processor. This program can determine the washing duration based on the degree of soiling of the clothes to be washed, ensuring washing effectiveness while saving washing resources and reducing washing costs.

[0070] In some embodiments of the present invention, both the first operating information and the second operating information include current parameters and / or torque parameters.

[0071] In some embodiments of the present invention, the control module 902 determines the pollutant weight according to the following model: W = k*(T-T0), where W represents the pollutant weight, T represents the first operating information, T0 represents the baseline operating information of the centrifugal motor when it is unloaded, and k represents the model parameter.

[0072] In some embodiments of the present invention, the control module 902 determines the predicted duration of the main washing stage according to the following model: T_main=a*W+b*T+c, where T_main represents the predicted duration of the main washing stage, W represents the weight of the contaminants, T represents the first operating information, and a, b, and c represent the model parameters respectively.
