Abstract
Description
Technical Field
[0001] This application relates to the field of smart home appliance technology, and more specifically, to a control method, device, washing machine and storage medium for a pulsator washing machine. Background Technology
[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. A top-loading washing machine is one type of washing machine. A top-loading washing machine has a disc-shaped impeller at the bottom of the tub with protruding ribs. Driven by the impeller, the water flow inside the tub forms a vortex that rotates clockwise and counterclockwise, causing the clothes to rotate and tumble, thus removing dirt from the clothes. Typically, in the initial stage of washing down garments, top-loading washing machines may cause clothes to float. Some floating areas do not come into contact with water and detergent, preventing the clothes from being thoroughly cleaned and resulting in poor washing performance.
[0003] Existing technologies disclose pressure caps for washing machines, but these traditional pressure caps require users to manually place them after putting in the clothes to prevent them from floating, which is quite cumbersome; moreover, pressure caps are generally an additional accessory and are prone to being lost, resulting in a poor user experience. Summary of the Invention
[0004] This application provides a control method, apparatus, washing machine, and storage medium for a pulsator washing machine, to at least solve the technical problem of how to reduce the floating of clothes.
[0005] According to a first aspect of the embodiments of this application, a pulsator washing machine is provided, comprising:
[0006] The washing chamber has an opening;
[0007] The washing chamber cover is placed over the opening of the washing chamber;
[0008] The pressure cap, connected to the top cover of the washing chamber, is located on the side of the top cover facing the washing chamber. When water is poured into the washing chamber and clothes are put in, and the top cover of the washing chamber is closed, the pressure cap is used to press the clothes below the water surface.
[0009] In these embodiments, by providing a pressure cap connected to the top cover of the washing chamber, after water is injected into the washing chamber and clothes are placed inside, the pressure cap can be used to press the clothes below the water surface when the top cover of the washing chamber is closed, reducing the floating of clothes and improving the washing effect. Furthermore, since the pressure cap is connected to the top cover of the washing chamber, compared to a separate pressure cap, there is no need to manually insert the pressure cap, and the pressure cap is less likely to be lost.
[0010] Optionally, the pressure cap is an inflatable pressure cap, and the pulsator washing machine further includes an inflation and de-inflation device connected to the inflatable pressure cap for inflating and de-inflating the inflatable pressure cap.
[0011] In these embodiments, an inflation cap and an inflation / de-inflation device are provided, which can inflate the cap when it is needed and de-inflate it when it is not needed, thus reducing the space occupied by the cap when it is not in use.
[0012] Optionally, the pulsator washing machine provided in this application embodiment further includes:
[0013] The telescopic device is connected to the washing chamber cover and the pressure cover, and the telescopic device extends and retracts in a direction perpendicular to the washing chamber cover.
[0014] In these embodiments, a telescopic device is provided and connected to the washing chamber cover and the pressure cap. When the pressure cap is not needed, the telescopic device is shortened, and when the pressure cap is needed, the telescopic device is extended. This can reduce the problem of the pressure cap being too low, which affects the user's ability to put clothes in the washing chamber.
[0015] Optionally, the pulsator washing machine provided in this application embodiment further includes:
[0016] The vision component is installed on the top cover of the washing chamber, on the side of the top cover facing the washing chamber, and is used to acquire images inside the washing chamber and process the acquired images;
[0017] The lighting device is installed on the top cover of the washing chamber, on the side of the top cover facing the washing chamber.
[0018] In these embodiments, by incorporating a vision component and a lighting device, it is possible to determine whether to use an air-filled pressure cap based on images captured inside the washing chamber, thereby enabling the air-filled pressure cap to function more effectively.
[0019] Optionally, the pressure cap is an inflatable pressure cap, and the pulsator washing machine further includes:
[0020] A connecting structure is used to connect the pressure cap and the washing chamber cover, and the connecting structure has a cavity inside;
[0021] An inflation and de-inflation device is installed inside the cavity. The inflation and de-inflation device is connected to the inflation cap and is used to de-inflate and inflate the inflation cap.
[0022] After the air inside the inflatable gland is drawn out, it contracts into the cavity of the connecting structure.
[0023] In these embodiments, by designing the air-filled cover to retract into the cavity of the connecting structure after the air is removed, the air-filled cover can be better stored when not in use, reducing the space occupied by the cover and minimizing its impact on the user's use of the washing machine. Furthermore, storing the air-filled cover within the cavity of the connecting structure also reduces the likelihood of damage to the cover.
[0024] Optionally, the pulsator washing machine provided in this application embodiment further includes:
[0025] Telescopic device, connecting the connecting structure and the washing chamber cover;
[0026] The vision component is installed on the top cover of the washing chamber, on the side of the top cover facing the washing chamber, and is used to acquire images inside the washing chamber and process the acquired images;
[0027] The lighting device is installed on the top cover of the washing chamber, on the side of the top cover facing the washing chamber.
[0028] In these embodiments, by providing a telescopic device, a vision component, and a lighting device, the image acquired by the vision component can be used to determine when to use the cover. When the cover needs to be used, the telescopic device is extended; when the cover does not need to be used, the telescopic device is shortened. This reduces the problem of the cover's position affecting the user's use of the washing machine when it is not needed.
[0029] A second aspect of this application also provides a control method for a pulsator washing machine, wherein the pulsator washing machine is the pulsator washing machine provided in this application embodiment, and the method includes:
[0030] Acquire images before water ingress;

[0032] Based on the images before and during water ingress, determine the floating state parameters of the clothing;
[0033] When the clothes are floating, the inflatable cap is inflated according to the floating parameters of the clothes. The inflatable cap then presses the clothes down to the bottom of the water.
[0034] In these embodiments, by determining the floating state parameters of the clothing based on the images before and after water ingress, and when the clothing is determined to be floating based on these parameters, the air-filled pressure cap is inflated, causing the air-filled pressure cap to press the clothing below the water surface. This allows for more accurate judgment of whether the clothing is floating based on changes in the images, thus making the need for the air-filled pressure cap more precise.
[0035] Optionally, the floating state parameters of the clothing include the ratio of the area of the darkened color region to the area of the reflective region;

[0041] The area ratio of the reflective region is determined based on the reflectivity parameters of the image before water ingress and the reflectivity parameters of the current image.
[0042] By observing the changes in color depth and reflective area, and based on the characteristic that clothing becomes darker and more reflective when soaked in water, it is possible to accurately determine whether clothing is floating.

[0045] For each color region in the image before water ingress, sum the values of each CMYK color parameter to obtain the first sum value; sum the values of each CMYK color parameter for the corresponding color region in the current image to obtain the second sum value.
[0046] If the first sum is less than the second sum, the corresponding color region in the current image is confirmed to be a region where the color has become darker.
[0047] Sum all the darker areas in the current image to get the area of the darker region.
[0048] Optionally, the HSB color parameter is the H value in the HSB color numerical value;
[0049] The step of determining the corresponding color regions in the current image for each color region in the pre-intake image based on the HSB color parameters of the pre-intake image and the current image includes:
[0050] If the difference between the H value of the HSB color value in the current image's color region and the H value of the HSB color value in the image before water ingress is less than a set threshold, the two color regions are determined to be corresponding.
[0051] Optionally, the reflectivity parameter includes reflectivity area;
[0052] Determining the reflectance parameters of the image before water ingress and the reflectance parameters of the current image includes:
[0053] The image before water ingress was converted to black and white to obtain the first image;
[0054] The current image is converted to black and white to obtain the second image;
[0055] The reflectivity area of the image before water ingress is determined based on the sum of the number of white pixels in the first image.
[0056] The reflectivity area of the image after water ingress is determined by summing the number of white pixels in the second image.
[0057] Optionally, determining clothing buoyancy based on clothing buoyancy parameters includes:
[0058] When the area of the darkened region is smaller than the first set value, the clothing is determined to float.
[0059] Optionally, determining clothing buoyancy based on clothing buoyancy parameters includes:
[0060] When the ratio of the reflective area of the image before water ingress to the reflective area of the current image is greater than a second set value, it is determined that the clothing is floating.
[0061] Optionally, before inflating the inflation cap, the control method for a pulsator washing machine provided in this application embodiment further includes:
[0062] Get the current water level value;
[0063] Based on the current water level, the inflation amount of the inflatable gland is generated;
[0064] Inflating the inflatable cap includes:
[0065] The inflation and depressurization device is controlled to inject gas corresponding to the inflation amount into the inflation cap.
[0066] In these implementations, by determining the inflation amount of the inflation gland based on the water level, inflation can be reduced when the water level is high and increased when the water level is low, thus avoiding unnecessary waste of power.
[0067] Optionally, before inflating the inflation cap, the control method for a pulsator washing machine provided in this application embodiment further includes:
[0068] Control the telescopic device to extend to a set length;
[0069] After inflating the inflatable gland, the following is also included:
[0070] After the washing process starts for a set time, the telescopic device is controlled to shorten the set length.

[0073] Based on the image before water ingress and the current image, determine the floating state parameters of the clothing;
[0074] If, based on the aforementioned clothing floating state parameters, it is determined that the clothing is not sufficiently wetted, the re-water intake process of the washing chamber is initiated.
[0075] After the washing chamber is refilled with water, the air pressure cap is inflated, causing it to press the clothes below the water surface.
[0076] A third aspect of this application provides a storage medium storing a computer program that, when executed by a processor, implements the control method for a pulsator washing machine provided in this application.
[0077] A control device for a pulsator washing machine includes a processor and a memory storing program instructions. The processor is configured to execute the control method for a pulsator washing machine provided in the embodiments of this application when executing the program instructions.
[0078] In this embodiment, by providing a pressure cap connected to the top cover of the washing chamber, after water is injected into the washing chamber and clothes are placed inside, the pressure cap can be used to press the clothes below the water surface when the top cover of the washing chamber is closed, reducing the floating of clothes and improving the washing effect. Furthermore, since the pressure cap is connected to the top cover of the washing chamber, unlike a separate pressure cap, it does not require manual insertion and is less likely to be lost.

Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0096] This application provides a control method, apparatus, washing machine, and storage medium for a pulsator washing machine, to at least solve the technical problem of how to reduce the floating of clothes.
[0097] like Figures 1 to 3 As shown, according to a first aspect of an embodiment of this application, a pulsator washing machine is provided, comprising:
[0098] The washing chamber 100 is equipped with an opening;
[0099] The washing chamber cover 200 is installed over the opening of the washing chamber 100;
[0100] The pressure cap 300 is connected to the washing chamber cover 200 and is located on the side of the washing chamber cover 200 facing the washing chamber 100. When the washing chamber 100 is filled with water and clothes are put in, and the washing chamber cover 200 is closed, the pressure cap 300 is used to press the clothes down below the water surface.
[0101] In these embodiments, by providing a pressure cap 300 connected to the washing chamber cover 200, after water is injected into the washing chamber 100 and clothes are placed inside, the pressure cap 300 can be used to press the clothes below the water surface when the washing chamber cover 200 is closed, reducing the floating of clothes and improving the washing effect. Furthermore, since the pressure cap 300 is connected to the washing chamber cover 200, compared to a separate pressure cap 300, there is no need to manually insert the pressure cap 300, and the pressure cap 300 is less likely to be lost.
[0102] Optionally, the cap 300 is circular in shape.
[0103] Optionally, the pressure cap 300 is an inflatable pressure cap 300, and the pulsator washing machine further includes an inflatable and deflatable device 400 connected to the inflatable pressure cap 300 for inflating and deflating the inflatable pressure cap 300.
[0104] In these embodiments, an inflation cap 300 and an inflation / de-inflation device 400 are provided so that the cap 300 can be inflated when it is needed and de-inflated when it is not needed, thereby reducing the space occupied by the cap 300 when it is not in use.

[0106] The telescopic device 500 is connected to the washing chamber cover 200 and the pressure cover 300, and the telescopic device 500 extends and retracts in a direction perpendicular to the washing chamber cover 200.
[0107] In these embodiments, a telescopic device 500 is provided and connected to the washing chamber cover 200 and the pressure cover 300. When the pressure cover 300 is not needed, the telescopic device 500 is shortened, and when the pressure cover 300 is needed, the telescopic device 500 is extended. This can reduce the problem of the pressure cover 300 being positioned too low, which affects the user's ability to put clothes in the washing chamber 100.

[0109] The vision component 600 is disposed on the washing chamber cover 200, located on the side of the washing chamber cover 200 facing the washing chamber 100, and is used to acquire images inside the washing chamber 100 and process the acquired images.
[0110] The lighting device 700 is installed on the washing chamber cover 200, located on the side of the washing chamber cover 200 facing the washing chamber 100.
[0111] In practical applications, the vision component 600 may include a camera and a data processing device. The camera is used to acquire images, and the data processing device is used to process the images acquired by the camera.
[0112] In these embodiments, by providing the vision component 600 and the lighting device 700, it is possible to determine whether to use the inflatable cover 300 based on the images collected inside the washing chamber 100, thereby enabling the inflatable cover 300 to function better.

[0114] A connecting structure 800 is used to connect the pressure cap 300 and the washing chamber cover 200. The connecting structure 800 has a cavity 801 inside.
[0115] An inflation and de-inflation device 400 is installed inside the cavity 801. The inflation and de-inflation device 400 is connected to the inflation cover 300 and is used to de-inflate and inflate the inflation cover 300.
[0116] After the air is drawn out of the inflatable cover 300, it retracts into the cavity 801 of the connecting structure 800.
[0117] In practical applications, the inflation and deflating device 400 can be installed at the bottom of the cavity 801 of the connecting structure 800 and connected to the inflation cap 300.
[0118] In these embodiments, by designing the air-retracted inflatable cover 300 to retract into the cavity 801 of the connecting structure 800 after the air is removed, the inflatable cover 300 can be better stored when not in use, reducing the space occupied by the inflatable cover 300 when not in use and thus minimizing its impact on the user's use of the washing machine. Furthermore, storing the air-retracted inflatable cover 300 within the cavity 801 of the connecting structure 800 also reduces the likelihood of damage to the inflatable cover 300.

[0120] Telescopic device 500 is connected between connecting structure 800 and washing chamber cover 200;
[0121] The vision component 600 is disposed on the washing chamber cover 200, located on the side of the washing chamber cover 200 facing the washing chamber 100, and is used to acquire images inside the washing chamber 100 and process the acquired images.
[0122] The lighting device 700 is installed on the washing chamber cover 200, located on the side of the washing chamber cover 200 facing the washing chamber 100.
[0123] In these embodiments, by providing the telescopic device 500, the vision component 600, and the lighting device 700, the image acquired by the vision component 600 can be used to determine when the pressure cover 300 should be used. When the pressure cover 300 needs to be used, the telescopic device 500 is extended; when the pressure cover 300 does not need to be used, the telescopic device 500 is shortened. This reduces the problem of the pressure cover 300's position affecting the user's use of the washing machine when it is not needed.
[0124] This application also provides a control device for a pulsator washing machine, including a processor and a memory storing program instructions. The processor is configured to execute the control method for a pulsator washing machine provided in this application when executing the program instructions.

[0128] S403. The processor determines the floating state parameters of the clothing based on the image before water ingress and the current image.

[0130] The current image corresponds to a state that can be either the state after the washing chamber 100 has been filled with water for the first time, or the state at a certain moment during the washing process after the washing chamber 100 has been filled with water for the first time.
[0131] In these embodiments, by determining the floating state parameters of the clothing based on the image before water ingress and the current image, and determining that the clothing is floating based on the floating state parameters, the inflatable pressure cap 300 is inflated, causing the inflatable pressure cap 300 to press the clothing below the water surface.

[0170] S1002. The processor generates the inflation amount of the inflation cap 300 based on the current water level value.
[0171] The inflation of the inflatable gland 300 includes:
[0172] The inflation and depressurization device 400 is controlled to inject gas corresponding to the inflation amount into the inflation cap 300.
[0173] In these embodiments, by determining the inflation amount of the inflation gland 300 based on the water level, inflation can be reduced when the water level is high and increased when the water level is low, thus avoiding unnecessary waste of power.
[0174] Optionally, before inflating the inflation gland 300, the control method for a pulsator washing machine provided in this application embodiment further includes:
[0175] The telescopic device 500 is controlled to extend to a set length.
[0176] In practical applications, the inflation volume can be determined as follows: Determine the water level height H2, and then calculate the height difference ΔH (i.e., ΔH = H1 - H2 - H3); where H1 is the height from the top cover to the bottom of the washing chamber 100, H2 is the water level height, and H3 is the length of the telescopic device 500. The length of the telescopic device 500 refers to its overall length after it has been extended to the set length.
[0177] Then, by multiplying the bottom area S of the inflatable cap by the height difference ΔH, the volume to be filled is obtained, and the inflation amount is deduced from this.

[0183] Based on the image before water ingress and the current image, determine the floating state parameters of the clothing;
[0184] If, based on the floating state parameters of the clothing, it is determined that the clothing is not sufficiently wetted, the re-water intake process of the washing chamber 100 is initiated.
[0185] After the re-injection process of the washing chamber 100 is completed, the air pressure cover 300 is inflated, so that the air pressure cover 300 presses the clothes under the water surface.
[0186] The determination of insufficient wetting of clothing can be made when the area of the darkened region is less than a third preset value, and the ratio of the reflective area of the image before water immersion to the reflective area of the current image is greater than a fourth preset value. The third preset value is greater than the first preset value, and the fourth preset value is less than the second preset value. In some embodiments, the determination of insufficient wetting of clothing can be made when the area of the darkened region is less than the third preset value.

[0192] S1105, The processor determines the reflectance parameters of the image before water ingress and the reflectance parameters of the current image;
[0193] S1106. The processor performs black-and-white conversion on the image before water ingress to obtain the first image;
[0194] S1107. The processor performs black-and-white conversion on the current image to obtain a second image;
[0195] S1108. The processor determines the reflectivity area of the image before water ingress based on the sum of the number of white pixels in the first image.
[0196] S1109. The processor determines the reflectivity area of the image after water ingress based on the sum of the number of white pixels in the second image.
[0197] S1110. When the area of the darkened region is less than the first set value, and the ratio of the reflective area of the image before water ingress to the reflective area of the current image is greater than the second set value, the processor determines that the clothing is floating.
[0198] S1111, The processor obtains the current water level value;
[0199] S1112. The processor generates the inflation amount of the inflatable pressure cap 300 based on the current water level value.
[0200] S1113. When the processor determines that the clothes are floating based on the floating state parameters, it controls the telescopic device 500 to extend to a set length and inflates the inflatable cover 300 so that the inflatable cover 300 presses the clothes down to the water surface.
