[0034] Embodiments of this disclosure 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 this disclosure, and should not be construed as limiting this disclosure.

[0035] The washing equipment, control method and apparatus, and storage medium of the present disclosure are described below with reference to the accompanying drawings.

[0036] Before introducing the control method and apparatus of the washing equipment disclosed herein, the washing equipment of this disclosure will be described accordingly. As shown in Figure 1, Figure 1 is a structural schematic diagram of the washing equipment in one embodiment of this disclosure. Taking a dishwasher as an example, the washing equipment includes a washing chamber 104, a filter screen 103, and a centrifugal motor 102. It also includes a washing pump 101 and a drain pump 105. When the dishwasher starts working, washing water is first supplied to the washing chamber 104. The washing pump 101 can control the circulation of the washing water in the washing chamber 104, the filter screen 103, and the spray arm. That is, after the washing water washes the clothes to be washed 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. The spray arm pressurizes and sprays the clothes to be washed in the washing chamber 104 for cleaning. During a washing stage, the centrifugal motor 102 can control the rotation of the filter screen 103 to improve its filtration effect. After all washing stages are completed, the washing water in the washing chamber 104 can be drained by the drain pump 105. It should be noted that in this embodiment, the filter screen 103 can be a circular stainless steel filter screen with a diameter of 20 cm and a thickness of 0.5 cm, and the mesh size can be 0.5 mm. The centrifugal motor 102 can be a brushless DC motor with a rated voltage of 12 volts, a rated power of 15 watts, and a maximum speed of 2500 rpm.

[0037] Figure 2 is a flowchart of a control method for a washing device according to an embodiment of the present disclosure.

[0038] Based on the above-mentioned washing equipment, this disclosure proposes a control method for the washing equipment, as shown in Figure 2. The control method for the washing equipment includes the following steps:

[0039] S10: After the washing equipment completes the preset washing stage, the washing parameters of the washing equipment are obtained.

[0040] Specifically, the washing equipment's execution 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 involves a rough rinse of the laundry, primarily to remove easily rinseable contaminants. The main wash and rinsing stages perform a more thorough cleaning of the laundry, while the drying stage dries the washed laundry. To maximize the lifespan of the washing equipment, this embodiment performs a self-cleaning process on the filter after each wash. Therefore, the preset washing stages in this embodiment may include at least one of the pre-wash, main wash, and rinsing stages. It is understood that contaminants usually remain in the filter after the washing stages. To prevent filter clogging, the filter can be controlled to rotate for self-cleaning. To more precisely control the filter's self-cleaning, this embodiment can first acquire the washing parameters of the washing equipment and determine the degree of filter self-cleaning required based on these parameters.

[0041] In some embodiments, the washing equipment further includes a washing pump, which controls the circulation of washing water within the washing chamber. Washing parameters include the operating current of the washing pump or the degree of clogging of the filter. Since the washing water needs to pass through the filter during circulation, if the filter is clogged, the operating current of the washing pump will change when controlling the circulation of the washing water. In other words, detecting the operating current can determine whether the filter is clogged and the degree of clogging. Alternatively, a sensor can be used to directly detect the pressure on the filter to determine whether the filter is clogged and the degree of clogging.

[0042] S20: If the washing parameters are greater than or equal to the preset washing parameters, the washing parameters are input into the preset model to determine the operating parameters of the filter.

[0043] Specifically, after obtaining the washing parameters of the washing equipment in step S10, these parameters can be further judged. If the washing parameters are greater than or equal to the preset washing parameters, it indicates that the filter needs to perform self-cleaning. The washing parameters can then be input into a preset model to determine the filter's operating parameters for precise cleaning. In this embodiment, the filter's operating parameters include the number of self-cleaning cycles and the rotation speed. That is, the rotation speed and the number of rotations of the filter can be determined based on the washing parameters. The correspondence between the operating parameters and the washing parameters in this embodiment can be established through a preset model. It should be noted that the relationship between the operating parameters and the washing parameters can also be calculated in advance and then stored in a table for direct retrieval, improving response speed.

[0044] S30 controls the operation of the centrifugal motor according to the operating parameters, so as to control the rotation of the filter screen for self-cleaning through the centrifugal motor.

[0045] Specifically, after determining the operating parameters of the filter screen in step S20, since the filter screen is controlled to rotate by a centrifugal motor, the operating parameters can be converted into control commands for the centrifugal motor to control the centrifugal motor, enabling the filter screen to rotate according to the operating parameters to achieve self-cleaning. In this embodiment, the relationship between the control commands of the centrifugal motor and the operating parameters can be determined based on a preset calculation model, and is not specifically limited here. The control commands can be PWM (Pulse Width Modulation) duty cycle.

[0046] In one embodiment of this disclosure, when the washing parameter is the operating current of the washing pump, the washing parameter is input into a preset model to determine the operating parameters of the filter screen, including: determining the rotation speed of the filter screen based on the basic rotation speed of the filter screen, the basic operating current of the washing pump, and the operating current; determining the number of self-cleaning cycles of the filter screen based on the basic operating current, the maximum operating current, and the operating current of the washing pump, wherein the basic rotation speed is the rotation speed of the centrifugal motor corresponding to when the filter screen is completely unclogged, the basic operating current is the operating current of the washing pump corresponding to when the filter screen is completely unclogged, and the maximum operating current is the operating current of the washing pump corresponding to when the filter screen is completely clogged.

[0047] Specifically, the preset model in this embodiment is: ω=max(ω0,ω0+α*(I-I0)), N=max(1,ceil(β*(I-I0) / (I max -I0)); where ω represents the rotational speed, N represents the number of self-cleaning cycles, ω0 represents the basic rotational speed of the centrifugal motor when the filter is completely unclogged, I represents the operating current of the washing pump, I0 represents the basic operating current of the washing pump when the filter is completely unclogged, I0 represents the maximum operating current of the washing pump when the filter is completely clogged, and α and β both represent model parameters.

[0048] More specifically, when the washing parameters are the operating current of the washing pump, the rotation speed of the filter and the number of self-cleaning cycles can be calculated using the aforementioned preset model. Basic parameters involved in the preset model, such as the basic rotation speed and basic operating current, can be obtained in advance. It should be noted that ceil is a rounding-up sign to ensure the number of self-cleaning cycles is an integer. This means that one self-cleaning cycle can be controlled by rotating the filter forward for a first preset duration followed by rotating it in reverse for a second preset duration. In this embodiment, the minimum rotation speed is set as the basic rotation speed to ensure the minimum filtration effect of the filter, while the minimum number of self-cleaning cycles is set to one, ensuring that the filter performs at least one self-cleaning cycle, guaranteeing the minimum cleanliness of the filter.

[0049] In another embodiment of this disclosure, when the washing parameter is the degree of clogging of the filter, the washing parameter is input into a preset model to determine the operating parameters of the filter, including: determining the rotation speed of the filter based on the basic rotation speed and the degree of clogging; and determining the number of self-cleaning cycles of the filter based on the degree of clogging, wherein the basic rotation speed is the rotation speed of the centrifugal motor when the filter is completely unclogging.

[0050] Specifically, the preset model in this embodiment is: ω=max(ω0,ω0+γ*B), N=max(1,ceil(θ*B)); where ω represents the rotation speed, N represents the number of self-cleaning cycles, ω0 represents the basic rotation speed of the centrifugal motor when the filter is completely unclogged, B represents the degree of clogging of the filter, and γ and θ both represent model parameters.

[0051] More specifically, when the washing parameter is the degree of clogging of the filter, the rotation speed and self-cleaning cycle number of the filter can be calculated using the above-mentioned preset model. The difference between this embodiment and the above embodiment is that this embodiment directly calculates based on the degree of clogging without the participation of the operating current, which can improve the calculation accuracy.

[0052] Summarizing the two embodiments above, we can obtain a table corresponding to a specific embodiment. Taking Table 1 as an example, it is shown in the table below:

[0053] Table 1

[0054] As shown in Table 1, the basic rotational speed in this specific embodiment can be 1800 rpm, and the basic operating current can be 0.8 amps. Simultaneously, as the degree of clogging increases, the rotational speed of the filter and the number of self-cleaning cycles also increase accordingly. For example, when the operating current of the circulation pump is detected to be 0.95 amps, the degree of clogging of the filter can be calculated as B = (0.95 - 0.8) / 0.55 ≈ 0.27, the rotational speed ω = max(1800, 1800 + 2182 * (0.95 - 0.8)) ≈ 1800 rpm, and the number of self-cleaning cycles N = max(1, ceil(3 * 0.27)) = 1.

[0055] In one embodiment of this disclosure, for the aforementioned preset model, as shown in FIG3, the control method of the washing equipment further includes: S301, obtaining the cleaning effect of the filter; S302, optimizing the model parameters based on the cleaning effect.

[0056] Specifically, after self-cleaning is completed, the cleaning effect of the filter is calculated and obtained. This can be determined based on factors such as the degree of clogging or cleanliness before and after cleaning. After determining the cleaning effect, it can be judged to determine whether the model parameters need to be optimized. It should be noted that the optimization method in this embodiment can be simulation, comparison, etc., and the specific method used is not limited here. After optimization, the cleaning effect of the washing equipment can be improved.

[0057] In one embodiment of this disclosure, as shown in FIG4, the control method of the washing equipment further includes: S401, if the washing parameters are less than the preset washing parameters, controlling the centrifugal motor to operate in a first preset mode, and entering the rinsing stage after the operation is completed. S402, after the rinsing stage is completed, controlling the centrifugal motor to operate in a second preset mode.

[0058] Specifically, if the washing parameters are determined to be less than the preset washing parameters, it can be determined that the filter is not currently clogged and can work normally. To further optimize the operation of the washing equipment, this embodiment also controls the centrifugal motor to operate in a first preset mode, and then enters the rinsing stage to operate in a second preset mode. More specifically, the first preset mode can be controlling the filter to rotate forward and reverse for 15 seconds and repeating for a first preset number of times, and the second preset mode can be controlling the filter to rotate forward and reverse for 30 seconds and repeating for a second preset number of times. The first and second preset numbers can both be obtained by looking up a table.

[0059] In a specific embodiment of this disclosure, as shown in Figure 5, after the pre-wash stage ends, the operating current of the washing pump is detected. Then, the rotation speed of the filter and the number of self-cleaning cycles are determined based on the washing pump. Self-cleaning is then performed based on this rotation speed and number of self-cleaning cycles. Specifically, the filter can be controlled to rotate forward and backward for 20 seconds each, cycling 5 times. Afterward, the drain pump is activated to remove contaminants. After the main wash stage ends, the operating current of the washing pump is continuously detected. If the operating current is greater than 0.9 amps, the rotation speed of the filter and the number of self-cleaning cycles are determined based on the washing pump. Self-cleaning is then performed based on this rotation speed and number of self-cleaning cycles. Specifically, the filter can be controlled to rotate forward and backward for 15 seconds each, cycling 8 times. Afterward, the drain pump is activated to remove contaminants. If the operating current is less than or equal to 0.9 amps, or if the self-cleaning corresponding to the main wash stage is completed, the centrifugal motor is controlled to operate in a first preset mode. Then, it is determined whether the rinsing stage has ended. If it has ended, the centrifugal motor is controlled to operate in a second preset mode. The first and second preset modes can be found in the description of the above embodiments and will not be repeated here.

[0060] In other embodiments, the filter screen may be composed of a multi-layer structure, each layer of which may be controlled by an independent centrifugal motor, and the self-cleaning strategies corresponding to different layers may be different. Of course, this disclosure may also set a control interface to select and trigger the self-cleaning program through the control interface.

[0061] In summary, the control method of the washing equipment in the embodiments of this disclosure can achieve filter self-cleaning, improve washing effect and washing efficiency, extend the service life of the washing equipment, and enhance the user experience.
