[0029] 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.

[0030] The washing equipment, control method and apparatus, and storage medium of the present invention are described below with reference to the accompanying drawings.

[0031] Before introducing the control method and apparatus of the washing equipment of the present invention, the washing equipment of the present invention will be described in detail, such as... Figure 1 As shown, Figure 1 This 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, a filter 103, and a centrifugal motor 102. It also includes a washing pump 101, a turbidity sensor 106, and a drain pump 105. When the dishwasher starts working, washing water is first supplied to the washing chamber 104. The washing pump 101 controls the circulation of the washing water in the washing chamber 104, the filter 103, and the spray arm. That is, after the washing water washes the items in the washing chamber 104, it is filtered through the filter 103 and then pumped by the washing pump 101 to the spray arm. The spray arm pressurizes the water to spray and clean the items in the washing chamber 104. During the washing process, the turbidity value of the washing water can be detected by the turbidity sensor 106, and the centrifugal motor 102 can control the rotation of the filter 103 to improve the filtration effect of the filter 103. After washing is 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 103 can be a circular stainless steel filter 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; the turbidity sensor 106 can have a measurement range of 0-1000 NTU (Nephelometric Turbidity Unit) and a measurement accuracy of ±2%.

[0032] Figure 2 This is a flowchart of a control method for a washing device in one embodiment of the present invention.

[0033] Based on the above-mentioned washing equipment, the present invention proposes a control method for the washing equipment, such as... Figure 2 As shown, the control method of this washing equipment includes the following steps:

[0034] S10: When the washing equipment is in the washing program, the water quality information of the washing water is obtained every first preset time interval.

[0035] Specifically, the working procedure of the washing equipment may include a pre-wash procedure, a main wash procedure, a rinsing procedure, and a drying procedure. The pre-wash procedure is a rough rinse of the clothes to be washed, mainly to remove easily rinsed contaminants. The main wash and rinsing procedures are for a more thorough cleaning of the clothes, while the drying procedure is for drying the washed clothes. The washing procedure in this embodiment mainly includes a main wash procedure and a rinsing procedure. In these procedures, water quality information of the washing water can be acquired at first preset intervals. Optionally, the first preset interval can be 4 seconds, 5 seconds, 6 seconds, etc. The water quality information may include the turbidity value of the washing water. Of course, other information about the washing water, such as total dissolved solids, can also be used to represent the water quality information; no specific limitation is made here.

[0036] S20 determines the target operating parameters of the filter screen based on water quality information.

[0037] S30 controls the centrifugal motor according to the target operating parameters to make the filter screen rotate for filtration.

[0038] Specifically, after obtaining the water quality information of the washing water, the target operating parameters of the filter can be determined based on this information. It can be understood that the filtration effect of the filter can be determined through the water quality information, and the target operating parameters can be determined based on the filtration effect. These target operating parameters can then be used to control the centrifugal motor to rotate the filter, thereby improving its filtration effect. In this embodiment, the target operating parameter can be the target rotation speed of the filter; however, in other embodiments, it could be the target number of rotations, etc., which is not specifically limited here. It should be noted that the higher the turbidity of the washing water, the higher the rotation speed of the filter, or the more rotations the filter needs to make.

[0039] The method uses water quality information (turbidity) as the reference and the target operating parameter (rotation speed) as the target rotation speed for explanation. Specifically, the turbidity value can be input into the calculation model, which will then calculate the target rotation speed. Optionally, the calculation model is: ω=k*T+ω0, where ω represents the target rotation speed, T represents the turbidity value, k represents the model coefficient (determined from experimental data), and ω0 represents the base rotation speed (determined from experimental data) to ensure the minimum filtration effect of the filter. Optionally, ω0 is 60 revolutions per minute, and k is 0.5.

[0040] More specifically, in this embodiment, the target operating parameters can be converted into PWM (Pulse Width Modulation) duty cycle through a conversion model, and the centrifugal motor can be controlled by the PWM duty cycle. The specific conversion model is: ω=Km*D*Vs / R, where ω represents the target speed, Km represents the speed constant of the centrifugal motor, D represents the PWM duty cycle (0≤D≤1), Vs represents the supply voltage of the centrifugal motor, and R represents the winding resistance of the centrifugal motor.

[0041] In some embodiments of the present invention, such as Figure 3 As shown, after controlling the centrifugal motor according to the target operating parameters, the method further includes:

[0042] S301, obtain the actual operating parameters of the filter.

[0043] S302 performs PID control on the centrifugal motor based on actual operating parameters and target operating parameters.

[0044] Specifically, after controlling the centrifugal motor according to the target operating parameters, the filter cannot be controlled to operate at the target operating parameters 100% due to losses and other reasons. Therefore, this embodiment also obtains the actual operating parameters of the filter, and then controls the centrifugal motor according to the actual operating parameters and the target operating parameters so that the rotation speed of the filter can gradually and smoothly approach the target operating parameters.

[0045] More specifically, through the PID model D(t)=Kp*e(t)+Ki*∫e(t)dt+K D *de(t) / dt calculates the PWM duty cycle of the centrifugal motor, and then controls the centrifugal motor based on this PWM duty cycle to control the filter to rotate at the target speed. In the PID model of this embodiment, D(t) represents the PWM duty cycle at time t, e(t) represents the difference between the target operating parameters and the actual operating parameters, Kp represents the proportional gain, Ki represents the integral gain, and K... D This represents the differential gain. Optionally, in this embodiment, Kp is set to 0.8, Ki is set to 0.2, and K... D Set it to 0.1.

[0046] In some embodiments of the present invention, the control method of the washing equipment further includes: acquiring the basic operating parameters of the filter screen; and controlling the centrifugal motor according to the basic operating parameters when it is determined from the water quality information that the washing water meets the preset conditions.

[0047] Specifically, in the washing program, the centrifugal motor continuously controls the filter based on the target operating parameters determined by the water quality information. However, when the water quality information determines that the washing water meets preset conditions, it indicates that the current filter effect is good. Therefore, to reduce energy consumption, the centrifugal motor can be controlled using basic operating parameters. These basic operating parameters can be the rotation speed corresponding to ensuring the minimum filtration effect of the filter. Furthermore, in this embodiment, the preset condition can be that the turbidity value of the washing water is less than a preset turbidity value and this condition persists for a second preset duration. The preset turbidity value can be 50 NTU, and the second preset duration can be 1 minute.

[0048] In other embodiments of the invention, the filter screen has a multi-layer filter screen structure, wherein the pore diameter of each layer of the filter screen structure is different. The washing device includes multiple centrifugal motors, which are arranged one-to-one with the multi-layer filter screen structure to control the rotation and filtration of each layer of the filter screen structure.

[0049] Specifically, for example, the filter screen includes a two-layer filter structure: a first-stage filter and a second-stage filter. The first-stage filter has a diameter of 30 cm and a pore diameter of 1 mm, while the second-stage filter has a diameter of 25 cm and a pore diameter of 0.3 mm. This embodiment may also include two turbidity sensors to detect the water quality information of the washing water after each filter stage. Based on this water quality information, the target operating parameters for the corresponding centrifugal motor are determined, and the centrifugal motor is then controlled using these target operating parameters to ensure that different filter stages operate at different speeds.

[0050] Figure 4 This is a flowchart of a control method for a washing device in a specific embodiment of the present invention.

[0051] like Figure 4 As shown, taking a dishwasher as an example, the process is as follows: First, the dishwasher is started. Then, the turbidity value of the washing water in the washing chamber of the dishwasher is detected. The target rotation speed of the filter is calculated based on the turbidity value. Then, the speed of the centrifugal motor is adjusted according to the target rotation speed to drive the filter to rotate. After that, it is determined whether the washing program of the floor cleaning equipment has ended. If it has ended, the current control method ends. If it has not ended, the turbidity value of the washing water is detected again.

[0052] In summary, the control method of the washing equipment in this embodiment of the invention can control the rotation of the filter screen according to the water quality, adjust the filtration effect of the filter screen, and greatly improve the user experience.

[0053] Furthermore, the present invention proposes a computer-readable storage medium having a control program for a washing device thereon, wherein when the control program is executed by a processor, it implements the control method for the washing device described in any of the above embodiments.

[0054] The computer-readable storage medium of this invention executes a control program for a washing device stored thereon via a processor, which can control the rotation of the filter screen according to the water quality and adjust the filtration effect of the filter screen, greatly improving the user experience.

[0056] Furthermore, such as Figure 5 As shown, the present invention proposes a control device 500 for a washing device.

The filter screen is used to filter the washing water in the washing chamber, and the centrifugal motor is used to control the rotation of the filter screen. The control device 500 includes an acquisition module 501, a determination module 502, and a control module 503.

[0058] In some embodiments of the present invention, after the control module 503 controls the centrifugal motor according to the target operating parameters, the acquisition module 501 is also used to acquire the actual operating parameters of the filter screen; the control module 503 is also used to perform PID control on the centrifugal motor according to the actual operating parameters and the target operating parameters.

[0059] In some embodiments of the present invention, the acquisition module 501 is further used to acquire the basic operating parameters of the filter screen; the control module 503 is further used to control the centrifugal motor according to the basic operating parameters when it is determined from the water quality information that the washing water meets the preset conditions.

[0060] In some embodiments of the present invention, water quality information includes water turbidity value, target operating parameters include target rotational speed, and basic operating parameters include basic rotational speed.

[0061] In some embodiments of the present invention, if the turbidity value of the washing water remains below a preset turbidity value for a second preset duration, it is determined that the washing water meets the preset conditions.

[0062] In some embodiments of the present invention, the filter screen has a multi-layer filter screen structure, wherein the diameter of the filter pores in each layer of the filter screen structure is different.
