Description

Technical Field

[0001] The present application relates to the field of home appliance control technology, and more specifically, to a fading processing method and device, a computer-readable storage medium, and a computer program product. Background Art

[0002] Existing washing machines are unable to recognize the color of clothes. When colored clothes are put into the washing machine, the color of the clothes may fade during the washing process. If this situation is not detected and handled in time, it will not only damage the clothes, but also contaminate other clothes, thereby reducing the user experience. The existing technology usually determines whether the clothes are faded by detecting the turbidity and conductivity of the water, or detecting the change rate of the washing water color in the washing machine and comparing it with the set value to determine whether the clothes are faded. However, these methods are greatly affected by water quality, have low detection accuracy, are prone to misjudgment, and cannot deal with faded clothes in time, nor can they effectively reduce the pollution caused by fading.

[0042] According to an embodiment of the present application, a method embodiment of a fading processing method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0043] Figure 2 is a flow chart of a fading processing method according to an embodiment of the present application, such as Figure 2 As shown, the method includes the following steps:

[0044] Step S202 , when it is determined that the permeability of the laundry in the inner drum of the washing machine reaches a preset permeability threshold, a first temperature of the inner drum is obtained, wherein the permeability represents the degree to which the laundry is soaked.

[0045] In this embodiment, the current first temperature in the inner drum of the washing machine can be obtained when the clothes in the inner drum are fully soaked (that is, the permeability of the clothes to be washed reaches a preset permeability threshold); the purpose of fully soaking the clothes here is to ensure that the clothes fully absorb water so that any potential fading dyes have the opportunity to dissolve in the water, so as to ensure the accuracy of subsequent fading analysis.

[0046] Step S204 , performing a heat radiation operation on the inner barrel until the radiation time of the heat radiation operation reaches a preset time, and obtaining a second temperature of the inner barrel.

[0047] In this embodiment, after obtaining the first temperature, the thermal radiation module can be used to heat the inner barrel. When the radiation time reaches the preset time, the current second temperature of the inner barrel can be obtained. This process should be performed immediately after the soaking achieves the expected effect to reduce the impact of temperature changes and other factors on the test results.

[0048] Step S206, when the temperature change rate calculated based on the first temperature, the second temperature and the radiation duration is greater than a preset change rate threshold, it is determined that there is a faded area in the inner barrel, and the position information of the faded area is obtained.

[0049] In this embodiment, when the laundry is fading, the colored molecules (dye) in the laundry will diffuse into the soaking water in large quantities. The specific heat capacity of water is 4186 J / (kg / cdotp℃). The specific heat capacity of the dye is usually an organic compound (such as azo dye, phthalocyanine dye, etc.), which is much lower than that of water, generally in the range of 1000-2500 J / (kg / cdotp℃). Therefore, when the dye is dissolved in the aqueous solution, the specific heat capacity of the mixed solution is: the weighted average of water and dye. It must be smaller than the specific heat capacity of the aqueous solution (equivalent to the fact that the dye molecules contribute a smaller specific heat capacity than pure water at the same mass), so when the colored minute in the clothes diffuses into the soaking water, the specific heat capacity of the soaking water will decrease accordingly, causing its heat absorption at the same time to increase, and then the rate of change of the heat absorption of the soaking water at the same time (i.e., the temperature change rate) can be compared to judge whether the clothes are fading; therefore, the first temperature, the second temperature and the radiation time obtained in the above steps can be used to analyze whether there is fading of clothes in the inner barrel. If there is fading, it is analyzed which specific area in the inner barrel has faded, and the location information of the faded area is obtained.

[0050] Step S208: Controlling the spraying device to spray the faded area at least according to the position information.

[0051] In this embodiment, the spray device can be controlled to spray water on the faded area based on the acquired position information to dilute the colored molecules and reduce dye contamination to other clothes.

[0052] It can be seen from the above that, through the technical solution provided by the above embodiments of the present application, when it is determined that the permeability of the clothes to be washed in the inner barrel of the washing machine reaches a preset permeability threshold, the first temperature of the inner barrel can be obtained, and the permeability represents the degree to which the clothes to be washed are soaked; then the inner barrel is subjected to a heat radiation operation until the radiation time of the heat radiation operation reaches a preset time, and the second temperature of the inner barrel is obtained; thereafter, when it is determined that there is a fading phenomenon in the inner barrel based on the first temperature, the second temperature and the radiation time, the position information of the faded area in the inner barrel is obtained; finally, the spray device is controlled to perform a spray operation on the faded area based on at least the position information, thereby achieving the purpose of judging whether there is a fading phenomenon by analyzing the temperature change rate in the washing machine barrel, and controlling the spray valve to spray the faded area when there is a fading phenomenon, and realizing the technical effect of quickly verifying whether there is a fading phenomenon in the clothes in the barrel by performing heat radiation treatment on the inner barrel, and spraying by controlling the spray valve to dilute it and avoid staining other clothes.

[0053] Therefore, the technical solution provided by the above-mentioned embodiments of the present application solves the technical problem in the related art that it is difficult to effectively detect and process faded clothes during the washing process, resulting in the pollution caused by fading affecting other clothes.

[0054] The following combination Figure 3 and Figure 4 The above embodiments of the present application are described in detail. Figure 3 is a schematic diagram of a washing machine according to an embodiment of the present application, Figure 4 is a flow chart of an optional fading processing method according to an embodiment of the present application; Figure 3 T1i is the first temperature inside the barrel collected by the temperature recognition module (i represents the i-th inner barrel sub-area); T2i is the second temperature inside the barrel collected by the temperature recognition module after radiation from the heat radiation module; t1 is the duration of heat radiation from the heat radiation module to the barrel (here equivalent to the preset duration in the embodiment of the present application); P is a critical value for determining whether the clothes are faded (i.e., the preset change rate threshold in the embodiment of the present application).

[0055] like Figure 3 As shown, before washing the clothes, water is first added according to the weight of the clothes to be washed, and after the water is added, the clothes to be washed are soaked to make the clothes fully wet.

[0056] In an optional embodiment of the present application, before obtaining the first temperature of the inner barrel, the fading processing method further includes: dividing the inner barrel into regions to obtain multiple inner barrel sub-regions; and recording sub-position information of each inner barrel sub-region.

[0057] like Figure 3 As shown, the main chip can also divide the inner drum into multiple inner drum sub-areas based on the initial plan, and the position coordinates of each inner drum sub-area (i.e., sub-position information) are calculated based on the size and shape of the washing machine inner drum and the layout of the temperature recognition module to facilitate subsequent determination of which area has faded. Specifically, when dividing the inner drum into areas, the division can be performed from multiple angles, without specific restrictions here. The following are some possible division methods: 1) Top-down view division: Looking down from the top of the washing machine drum, the inner drum area can be divided into multiple grid areas or sector areas. In this way, each area has its own specific coordinate position, which can be expressed in rectangular coordinates (X, Y). The temperature recognition module will collect temperature information in these areas respectively; for example, the space inside the barrel can be divided into four equally divided fan-shaped areas, each area has its own specific coordinates and corresponding temperature recognition module, so that the initial temperature T1i and the temperature T2i after heat radiation of each area can be accurately recorded; 2) Depth angle division: In addition to the horizontal division, the barrel can also be partitioned in the vertical direction, for example, the space inside the barrel can be divided into three areas: upper, middle and lower. This can monitor the temperature changes of different water layers and obtain richer data; 3) Comprehensive division: The above two division methods may be combined to form a three-dimensional temperature collection grid. The temperature recognition module collects temperature information at multiple coordinate points in the horizontal and vertical directions to more comprehensively monitor the temperature changes of the entire barrel space.

[0058] Similarly, since the inner barrel is divided into multiple inner barrel sub-areas, the first temperature of the inner barrel includes multiple first sub-temperatures, and the second temperature includes multiple second sub-temperatures. The first sub-temperature and the second sub-temperature are the temperatures of each inner barrel sub-area before and after heat radiation, respectively.

[0059] In a specific embodiment of the present application, when it is determined that the permeability of the clothes to be washed in the inner barrel of the washing machine reaches a preset permeability threshold, the first temperature of the inner barrel is obtained, including: when it is determined that the permeability of the clothes to be washed reaches the preset permeability threshold, using the temperature acquisition component to collect the first current temperature of each inner barrel sub-area to obtain multiple first sub-temperatures.

[0060] Optionally, the temperature acquisition component may include but is not limited to a temperature recognition module, a temperature sensor, and other components that can be used to detect temperature.

[0061] In order to ensure the accuracy of the temperature change rate analysis, a high-resolution temperature sensor (such as a PT100 probe + data logger) can be used to accurately collect the temperature data of the solution in the inner barrel to accurately analyze the changes that occur.

[0062] Specifically, such as Figure 3 and Figure 4 As shown, when it is determined that the permeability of the clothes to be washed reaches the preset permeability threshold, the position coordinates of each inner barrel sub-area previously obtained can be used to guide the temperature recognition module 1 to collect the current temperature of each inner barrel sub-area (here refers to the first current temperature) to obtain the first sub-temperature T1i of each inner barrel sub-area.

[0063] In another specific embodiment of the present application, a heat radiation operation is performed on the inner barrel until the radiation time of the heat radiation operation reaches a preset time, and then the second temperature of the inner barrel is obtained, including: controlling the heat radiation component to perform the heat radiation operation to perform heat radiation on the inner barrel; when the radiation time of the heat radiation operation reaches a preset time, using the temperature acquisition component to acquire the second current temperature of each inner barrel sub-area to obtain multiple second sub-temperatures.

[0064] Specifically, such as Figure 3 and Figure 4 As shown, after the heat radiation module 3 is controlled to radiate heat to the inner barrel for a radiation time period reaching the preset time period t1, the position coordinates of each inner barrel sub-area previously obtained can be used to guide the temperature recognition module 1 to collect the current temperature of each inner barrel sub-area (here referred to as the second current temperature) to obtain the second sub-temperature T2i of each inner barrel sub-area.

[0065] It should be noted that when using the temperature recognition module for temperature collection, only one temperature recognition module can be used to collect the temperatures of different areas in the barrel, or multiple temperature recognition modules can be used to collect the temperatures of different areas in the barrel, as follows: 1) Multi-point measurement of a single temperature recognition module: Only one temperature recognition module is deployed in the washing machine. It can move or have multiple sensor heads to cover multiple preset inner barrel sub-areas in the washing machine barrel. After staying in each inner barrel area and measuring the temperature, the information is fed back to the main chip as a basis for subsequent processing. The advantage of this method is that it reduces the number of temperature recognition modules, simplifies the complexity of the equipment, and reduces costs; 2) Distributed measurement of multiple temperature recognition modules: An independent temperature recognition module is installed in each inner barrel sub-area in the barrel. These modules are each responsible for the temperature measurement of an area. This method can more accurately measure the temperature changes in each area and improve the resolution and accuracy of the detection, but it may increase the cost and complexity of the equipment. In actual application, you can choose which method to use for temperature collection based on actual conditions, and there is no specific restriction here.

[0066] In a specific embodiment of the present application, when the temperature change rate calculated based on the first temperature, the second temperature and the radiation time is greater than a preset change rate threshold, it is determined that there is a fading area in the inner barrel, and the position information of the fading area is obtained, including: calculating the sub-temperature difference between each second sub-temperature and the corresponding first sub-temperature; calculating the ratio of each sub-temperature difference to the radiation time to obtain the sub-temperature change rate of the corresponding inner barrel sub-area; when it is determined that at least one sub-temperature change rate is greater than the corresponding sub-preset change rate threshold, the corresponding inner barrel sub-area is determined to be a fading area; and determining the sub-position information of the inner barrel sub-area as the position information of the fading area.

[0067] Optionally, the above-mentioned first temperature includes multiple first sub-temperatures, the second temperature includes multiple second sub-temperatures, the inner barrel includes multiple inner barrel sub-areas, the preset change rate threshold includes multiple sub-preset change rate thresholds, and the number of first sub-temperatures, second sub-temperatures, inner barrel sub-areas and sub-preset change rate thresholds is the same.

[0068] like Figure 3 As shown, the main chip can calculate the temperature change rate ∆Ti / ∆t of each inner barrel sub-area in the barrel based on T1i, T2i, and t1, and compare ∆Ti / ∆t with the sub-preset change rate threshold Pi corresponding to the inner barrel sub-area (Pi is the sub-preset change rate threshold corresponding to the i-th inner barrel sub-area). This can determine whether the clothes in the barrel are fading. If the temperature change rate ∆Ti / ∆t of all inner barrel sub-areas is not greater than Pi of the corresponding inner barrel area, it is determined that there is no fading in the barrel, that is, there are no faded clothes. If the temperature change rate ∆Ti / ∆t of at least one inner barrel sub-area is greater than Pi of the corresponding inner barrel area, it is determined that there is fading in the barrel, that is, there are faded clothes.

[0069] like Figure 3 and Figure 4 As shown, when there is no fading phenomenon in the inner barrel of the washing machine, the washing machine can be controlled to wash according to the normal process; when there is fading phenomenon in the inner barrel of the washing machine, the main chip can further analyze which inner barrel sub-area or areas have a temperature change rate greater than Pi of the corresponding inner barrel area, and then the inner barrel sub-area with a temperature change rate greater than Pi of the corresponding inner barrel area can be divided into a fading molecular area 4 (i.e., a fading area), and the inner barrel area with a temperature change rate not greater than Pi of the corresponding inner barrel area can be divided into a non-fading molecular area 5; thereafter, the position information of the fading molecular area 4 can be determined according to the position coordinates of each inner barrel sub-area recorded previously, so as to facilitate the subsequent decision on how to control the spray valve 2 (i.e., the spray device in the embodiment of the present application) to avoid dyeing contamination of other clothes.

[0070] In an optional embodiment of the present application, before determining that at least one sub-temperature change rate is greater than the corresponding sub-preset change rate threshold, the fading processing method further includes: using a material detection model to perform material analysis on the clothes to be washed in each inner barrel sub-area to obtain a target clothing material in each inner barrel sub-area, wherein the material detection model is trained using multiple sets of first training data, each of the multiple sets of first training data includes: sample clothes, and a sample material type corresponding to the sample clothes; inputting the target clothing material into the temperature change analysis model to analyze the target sub-temperature change rate of the target clothes during the heat radiation process using the temperature change analysis model, and determining the target sub-temperature change rate as the sub-preset change rate threshold corresponding to the inner barrel sub-area, wherein the target clothes refer to clothes to be washed whose clothes material is the target clothes material, and the temperature change analysis model is trained using multiple sets of second training data, each of the multiple sets of second training data includes: sample clothes material, and a sample temperature change rate of the sample clothes whose clothes material is the sample clothes material during the heat radiation process, and the heat radiation process is a process of radiating a solution containing clothes to be washed using a heat radiation component for a preset time.

[0071] In this embodiment, due to the different materials of the clothes, the response to thermal radiation will also be different. Some may release colored molecules more easily when fading, while others are more stable. Therefore, under the same thermal radiation conditions, the temperature change rate will be different depending on the speed and amount of the colored molecules released. If only a fixed temperature change rate threshold is set to judge whether fading has occurred based on the temperature change rate of the solution in the inner barrel, misjudgment may occur; therefore, the embodiment of the present application introduces a material detection model and a temperature change analysis model, that is, first use the material detection model to analyze the material of the clothes in each inner barrel sub-area, and then use the temperature change analysis model, which is a model that has learned the behavior patterns of clothes of various materials under thermal radiation based on a large amount of training data, to analyze the temperature change rate of the clothes of this material when fading during the thermal radiation process, so as to dynamically set the sub-preset change rate threshold adapted to the material to improve the accuracy and sensitivity of fading detection.

[0072] The material detection model and temperature change analysis model here are both trained using a large amount of corresponding training data through machine learning, deep learning, or data analysis. The specific training process will not be repeated here.

[0073] It should be noted that the thermal radiation process of the sample clothes during the training of the temperature change analysis model and the thermal radiation process of the current clothes to be washed during the actual detection process should be the same, that is, the thermal radiation intensity and radiation duration of the thermal radiation component are the same, so as to avoid differences in the temperature change rate of the solution due to differences in the external environment, thereby avoiding misjudgment.

[0074] In addition, it should be noted that when training the temperature change analysis model, the sample clothing corresponding to the sample clothing material in the training data should be selected from clothing that easily fades when exposed to water to avoid inaccurate threshold setting. In a specific embodiment of the present application, at least based on the position information, the spray device is controlled to perform a spray operation on the faded area, including: determining the spray angle of the spray device based on the position information, wherein the spray angle is the angle at which the area corresponding to the position information is sprayed; obtaining the water turbidity of the faded area and the unit water output of the spray device, wherein the water turbidity represents the degree of turbidity of the water; determining the spraying time of the spray device based on the water turbidity and the unit water output; and controlling the spray device to perform a spray operation on the faded area according to the spray angle and the spraying time.

[0075] like Figure 3 As shown, the main chip can adjust the spray angle of the spray valve 2 according to the acquired position information of the fading molecular area 4 so that it can accurately spray the fading molecular area 4. It can also analyze how long the spray valve needs to continue spraying water to effectively dilute and break up the colored molecules in the fading molecular area 4 according to the turbidity of the water in the current fading molecular area 4 and the water output of the spray valve 2 per unit time, so as to determine the spray time of the spray valve 2. After that, the spray valve 2 can be controlled to spray water to the fading molecular area 4 according to the spray angle and spray time obtained by analysis, so as to dilute the colored molecules in the fading molecular area 4, avoid secondary damage during the washing process, and improve the user experience.

[0076] It should be noted that, when the fading area contains only one inner barrel sub-area, the spray valve can be directly controlled to spray toward the inner barrel sub-area; when the fading area contains multiple inner barrel sub-areas, the spray valve can be controlled to spray toward each of these faded inner barrel sub-areas one by one in turn, or, if these faded inner barrel sub-areas are adjacent, the sub-position information of these adjacent inner barrel sub-areas can be integrated (including but not limited to) to obtain the position information of a larger area composed of these adjacent areas, and then the angle of the spray valve can be adjusted according to the position information to control the spray valve to spray toward the area obtained by the combination. The selection can be made based on the actual situation and there is no specific restriction here.

[0077] In an optional embodiment of the present application, the fading processing method further includes: generating a fading warning signal when it is determined that fading exists in the inner barrel based on the first temperature, the second temperature and the radiation duration.

[0078] Specifically, such as Figure 4As shown, when fading is detected in the drum of the washing machine, the main chip can generate a fading warning signal, such as using a flashing light, a prompt sound, a voice broadcast, and displaying a warning message through a smart APP to remind the user that fading has occurred during the current washing process, so that the user can know or take corresponding measures to minimize the impact of clothing fading.

[0079] In another optional embodiment of the present application, the fading processing method further includes: in the process of controlling the spraying device to perform a spraying operation on the fading area at least according to the position information, opening the drain valve according to a predetermined time period.

[0080] Specifically, such as Figure 4 As shown, in the process of controlling the spray valve 2 to spray water on the fading molecule area 4, the drain valve can also be opened periodically to use the moving water (flowing water) to remove the colored molecules to avoid colored pollution to other clothes.
