Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and more particularly to a clothing processing method, electronic equipment, and clothing processing equipment. Background Technology

[0002] Clothing processing equipment, for example, is an indispensable part of daily life. It performs processes such as washing, dehydration, drying, and care for clothing, greatly improving the convenience of clothing handling. With technological advancements and increasing user demands, the precision of clothing processing equipment has also improved. For instance, modern washing machines typically identify the material of the clothing before processing, allowing different processing parameters to be applied to different materials, thus improving the overall processing effect.

[0003] Currently, most material recognition methods rely on cameras and other photographic devices to capture images of clothing and then use image algorithms to identify the material. However, in practical use, clothing can easily obstruct the camera, and the camera may also experience water vapor buildup or fail to autofocus, resulting in poor image clarity and reduced accuracy in material recognition. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing methods for detecting clothing materials have low accuracy. The invention provides a clothing processing method, electronic device and clothing processing equipment that can not only accurately detect the clothing material in the clothing processing drum, but also assess the weight of different clothing materials.

[0006] Determine the weight change of the clothes in the clothes treatment drum before and after water absorption;

[0007] The material parameter changes of the clothes before and after water absorption in the clothes processing drum are determined. The material parameters are determined based on the light signal collected by the light signal detection device, which is located inside the clothes processing drum and is used to collect the light signal after the clothes diffusely reflect the incident light signal.

[0008] Based on the changes in the material parameters and the variation patterns of parameter values ​​before and after water absorption for different clothing materials, the clothing material inside the clothing treatment drum is determined.

[0044] In conjunction with the first aspect, in one implementation of the first aspect, the weight change pattern of the different clothing materials before and after water absorption includes the amount of water absorbed per unit weight of the different clothing materials.

[0045] The step of evaluating the weight of different clothing materials in the clothing treatment drum based on the clothing material inside the drum, the weight change value, and the weight change pattern of different clothing materials before and after water absorption includes:

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0073] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply differentness.

[0074] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0075] Clothing processing equipment is an indispensable part of daily life, capable of performing processes such as washing, dehydration, drying, and care for clothing, greatly improving the convenience of clothing handling. With technological advancements and increasing user demands, the precision of clothing processing equipment has also improved. Taking washing machines as an example, current models typically identify the material of the clothing before processing, allowing different processing parameters to be applied to different materials, thus improving the processing effect.

[0076] Material identification methods include camera recognition, which involves taking pictures of clothing with a camera and then using image algorithms to analyze the material of the clothing from the images.

[0077] However, in actual use, it has been found that camera recognition is often affected by factors such as ambient brightness and water mist, resulting in poor image clarity of clothing and reduced accuracy in identifying clothing materials.

[0078] Based on this, the present application provides a clothing processing method that can relatively accurately detect the clothing material and assess the weight of different clothing materials. By using the clothing material and corresponding weight as a reference for clothing processing, it is beneficial to improve the targeting of subsequent clothing processing and improve the effect of subsequent clothing processing.

[0079] Figure 1 This is a schematic flowchart of a clothing processing method according to an embodiment of this application. (Refer to...) Figure 1The clothing treatment methods include the following processes.

[0080] S100: Determine the weight change of the clothes in the clothes treatment drum before and after water absorption.

[0081] In this embodiment, the weight change of the clothes before and after water absorption can be obtained by measuring the weight of the clothes in the clothes processing drum before and after water absorption.

[0082] S102: Determine the changes in material parameters of the clothes before and after water absorption in the clothes processing drum. The material parameters are determined based on the light signal collected by the light signal detection device, which is located inside the clothes processing drum and is used to collect the light signal after diffuse reflection of the incident light signal by the clothes.

[0083] In this embodiment, the material parameters of the clothing before and after absorbing water can be detected, and the difference can be calculated to obtain the change value of the material parameters.

[0084] For example, the material parameter value is the light intensity or wavelength of the acquired light signal itself, or the material parameter value is used to reflect the light intensity or wavelength of the acquired light signal.

[0085] In this embodiment, when identifying the material of clothing, the optical signal detection device emits an incident light signal towards the clothing. The incident light signal undergoes diffuse reflection upon contact with the clothing. This embodiment uses the optical signal detection device to acquire the diffusely reflected light signal. The optical signal detection device, or a corresponding processor, can convert the acquired light signal into a specific numerical value for calculation, hereinafter referred to as the sampled value.

[0086] Optionally, in one implementation of this embodiment, while the garment processing drum remains stationary (i.e., the state of the garments inside the drum remains unchanged), an incident light signal is emitted towards the garments via a light signal detection device, and diffusely reflected light signals are received. This process is repeated multiple times to obtain multiple sampled values ​​reflecting the intensity or wavelength of the diffusely reflected light signals. The aforementioned parameter value is then calculated based on these multiple sampled values. The parameter value can be the average or median value of the multiple sampled values, etc.

[0087] Next, you can rotate the garment processing drum to change the state of the garments, then keep the drum stationary and repeat the process. By repeating this multiple times, you can obtain multiple parameter values ​​to cover as many garment materials as possible within the processing drum.

[0088] S104: Determine the material of the clothing in the clothing treatment drum based on the changes in the material parameters and the changes in the parameter values ​​of different clothing materials before and after water absorption.

[0089] The variation pattern of parameter values ​​before and after water absorption for different clothing materials includes the range of variation of material parameter values ​​before and after water absorption for different clothing materials. In other words, this embodiment can pre-determine the range of variation of material parameter values ​​before and after water absorption for each of a variety of clothing materials.

[0090] The variation range of material parameter values ​​before and after water absorption for each type of clothing material is a numerical range. Knowing the clothing material, diffuse reflection experiments can be performed on the clothing before and after water absorption, and the obtained parameter values ​​can be statistically analyzed and determined. According to the inventor's research and experiments, the variation range of material parameter values ​​before and after water absorption differs for different materials, thus it can be used for material identification.

[0091] S106: Based on the clothing material in the clothing treatment drum, the weight change value, and the weight change pattern of different clothing materials before and after water absorption, evaluate the weight of different clothing materials in the clothing treatment drum.

[0092] Using the method provided in this embodiment, on the one hand, by determining the change in material parameters of the clothes in the clothes processing drum before and after water absorption, and based on the change in material parameters and the change pattern of parameter values ​​before and after water absorption for different clothes materials, the material of the clothes in the clothes processing drum can be determined relatively accurately; on the other hand, by determining the change in weight of the clothes in the clothes processing drum before and after water absorption, and based on the material of the clothes in the clothes processing drum, the change in weight, and the change pattern of weight of different clothes materials before and after water absorption, the weight of different clothes materials in the clothes processing drum can be evaluated.

[0093] Using the method provided in this embodiment, the state of clothing before and after water absorption can be obtained through water intake and drainage. Furthermore, the material of clothing can be identified and the weight of different clothing materials can be assessed simultaneously through a single water intake and drainage process, which helps to improve the targeting of subsequent clothing processing and enhance the effectiveness of clothing processing.

[0094] Optionally, in one implementation of this embodiment, the clothes in the clothes processing drum can be made to enter the clothes absorbing state in the following way.

[0095] First, fill the garment processing drum with water until it completely submerges the garments inside. Then, wait for the garments to be completely submerged for a set time (e.g., 10 minutes, to allow the garments to fully absorb water; the specific time can be determined based on experience or experimentation, and will not be elaborated here). After the garments have been completely submerged for the set time, drain the water from the garment processing drum that has not been absorbed by the garments, thus achieving the state of the garments being fully absorbed. In this state, the garments are fully absorbed.

[0096] The water that has not been absorbed by the clothes can be naturally drained from the clothes processing drum by opening the drain valve and keeping it open for a set time, so as to ensure that the clothes are fully hydrated.

[0097] Using this method, fully absorbent clothing can be obtained through water intake and drainage processes.

[0098] Optionally, in one implementation of this embodiment, the weight change of the clothes in the clothes treatment drum before and after absorbing water is determined in the following way.

[0099] Figure 2 This is a schematic flowchart illustrating the process of determining the change in material parameters of clothes before and after water absorption in a clothes processing drum, according to an embodiment of this application. (Refer to...) Figure 2 The method includes the following processing.

[0100] S200: When the clothes are dry, obtain multiple first material parameter values, and each first material parameter value corresponds to a different state of the clothes.

[0101] Optionally, in one implementation of this embodiment, while the clothes are dry, the clothes processing drum is rotated a set number of times. After each rotation of the clothes processing drum, the optical signal detector emits the incident light signal and receives the light signal after diffuse reflection of the incident light signal. The first material parameter value corresponding to the current state of the clothes is determined based on the light signal received by the optical signal detector. The purpose of rotating a set number of times is to ensure that the detection of the optical signal detector can cover all clothing materials in the clothes processing drum. The value can be obtained based on experience and experiments; for example, it can be 10 times.

[0102] S202: When the clothing is in a water-absorbing state, obtain multiple second material parameter values, and each second material parameter value corresponds to a different clothing state.

[0103] Optionally, in one implementation of this embodiment, when the clothing is in a water-absorbing state, the clothing processing drum is rotated a set number of times. After each rotation of the clothing processing drum, the optical signal detection device is controlled to emit the incident light signal and receive the light signal after diffuse reflection of the incident light signal. The second material parameter value corresponding to the current clothing state is determined based on the light signal received by the optical signal detection device. The purpose of rotating a set number of times is to ensure that the detection of the optical signal detection device can cover all clothing materials in the clothing processing drum. The value can be obtained based on experience and experiments; for example, it can be 10 times.

[0104] In other words, in this embodiment, each first material parameter value / second material parameter value corresponds to a garment state. The "garment state" refers to the distribution of garments within the garment processing drum (e.g., the shape and area of ​​the garments as observed from above). Furthermore, this application assumes that whenever the garment processing drum rotates (e.g., more than one revolution), the garment state will randomly change, and the changed state will not repeat. Without considering extreme cases or extremely low probabilities, this assumption aligns with reality and ensures the practicality of the proposed solution.

[0105] S204: Based on the correspondence between the plurality of first material parameter values ​​and the first reference parameter values ​​in the dry state of the clothing, at least one first parameter value for performing difference calculation is determined.

[0106] Each of the first reference parameter values ​​corresponds to a type of clothing material. That is, a first reference parameter value is used to represent a type of clothing material with a high probability (i.e., the corresponding clothing has a high probability of being made of that material).

[0107] For example, under an incident light signal of a certain wavelength, the detectable clothing materials and their corresponding first reference parameter values ​​in this embodiment are as follows: Cotton: 45; Linen: 80; Silk: 120; Wool: 150; Polyester fiber: 130; Synthetic fiber: 155. The first reference parameter values ​​for different clothing materials can be determined based on the diffuse reflection light signal collected by the optical signal detection device when the clothing is dry. For example, the ratio of the first reference parameter values ​​for different clothing materials can represent the ratio of the intensity (or wavelength) of the diffuse reflection light signal collected by the optical signal detection device for different clothing materials.

[0108] Optionally, in one implementation of this embodiment, the first reference parameter value in the dry state of the clothing includes multiple first reference parameter values ​​corresponding to various clothing materials, and each first reference parameter value is set with a threshold range. For example, the threshold range for cotton is (35, 50); the threshold range for linen is (75, 85); the threshold range for silk is (110, 125); the threshold range for wool is (145, 152); the threshold range for polyester fiber is (126, 135); and the threshold range for synthetic fiber is (153, 162).

[0109] Optionally, in one implementation of this embodiment, at least one first parameter value for difference calculation is determined in the following manner: determining which threshold range of the first reference parameter value each of the plurality of first material parameter values ​​falls into, thereby establishing a mapping relationship between the plurality of first material parameter values ​​and the plurality of first reference parameter values, wherein the number of the at least one first parameter value is the same as the number of first reference parameter values ​​mapped to the first material parameter values; for each first reference parameter value mapped to the first material parameter value, determining its corresponding first parameter value based on the first material parameter value it is mapped to, thereby obtaining the at least one first parameter value.

[0110] For example, assuming the detected 10 values ​​of the first material parameter are: 78, 81, 83, 120, 124, 110, 112, 127, 130, and 135, the following mapping relationship can be established:

[0111] 78, 81, 83-80 (hemp);

[0112] 120, 124, 110, 112—120 (silk);

[0113] 127, 130, 135-130 (polyester fiber).

[0114] Based on the above mapping relationship, the first parameter value corresponding to the first reference parameter value (80, hemp) can be obtained respectively. Taking the first mapping relationship as an example, the first parameter value can be selected from the average, median, maximum, and minimum values ​​of the first material parameter values ​​(78, 81, 83) corresponding to the first reference parameter value (80, hemp), or the first reference parameter value (80) can be directly selected as the first parameter value. Those skilled in the art should understand that there are many rules for calculating the first parameter value, but the selected rules must be consistent, and it is not possible to select the average value for the first mapping relationship and the median for the second mapping relationship.

[0115] For how to calculate the first parameter value for other mapping relationships, please refer to the examples above; they will not be elaborated here.

[0116] S206: Based on the correspondence between the plurality of second parameter values ​​and the second reference parameter values ​​in the water-absorbing state of the clothing, at least one second parameter value for performing difference calculation is determined.

[0117] Each of the second reference parameter values ​​corresponds to a type of clothing material. That is, a second reference parameter value is used to represent a type of clothing material with a high probability (i.e., the probability that the corresponding clothing belongs to that type of clothing material is relatively high).

[0118] For example, under an incident light signal of a certain wavelength, the detectable clothing materials and their corresponding second reference parameter values ​​in this embodiment are as follows: Cotton: 65; Linen: 95; Silk: 130; Wool: 180; Polyester fiber: 175; Synthetic fiber: 205. The second reference parameter values ​​for different clothing materials can be determined based on the diffuse reflection light signal collected by the optical signal detection device when the clothing is wet. For example, the ratio of the second reference parameter values ​​for different clothing materials can represent the ratio of the intensity (or wavelength) of the diffuse reflection light signal collected by the optical signal detection device for different clothing materials.

[0119] Optionally, in one implementation of this embodiment, the second reference parameter value when the clothing is in a water-absorbing state includes multiple second reference parameter values ​​corresponding to various clothing materials, and each second reference parameter value is set with a threshold range, which is similar in form to the threshold range of the first reference parameter value. The specific values ​​are not described here.

[0120] Optionally, in one implementation of this embodiment, at least one second parameter value for difference calculation is determined in the following manner: determining which threshold range of the second reference parameter value each of the plurality of second material parameter values ​​falls into, thereby establishing a mapping relationship between the plurality of second material parameter values ​​and the plurality of second reference parameter values, wherein the number of the at least one second parameter value is the same as the number of second reference parameter values ​​mapped to the second material parameter value; for each second reference parameter value mapped to the second material parameter value, determining its corresponding second parameter value based on the second material parameter value it is mapped to, thereby obtaining the at least one second parameter value.

[0121] For details on how to determine the value of the second parameter, please refer to the previous section on how to determine the value of the first parameter; it will not be repeated here.

[0122] S208: Calculate at least one material parameter change value based on the at least one second parameter value and the at least one first parameter value. The number of the at least one first parameter value, the at least one second parameter value, and the at least one material parameter change value is the same.

[0123] Optionally, in one implementation of this embodiment, the at least one second parameter value is sorted in ascending order; the at least one first parameter value is sorted in ascending order; the absolute value of the difference between the second parameter value and the first parameter value at the same sorting position in each ascending order is calculated to obtain at least one material parameter change value. For example, assuming the first parameter values ​​are a1, a2, a3 in ascending order, and the second parameter values ​​are c1, c2, c3 in ascending order, the calculated material parameter change values ​​are |c1-a1|, |c2-a2|, and |c3-a3|, respectively.

[0124] Using the method provided in this embodiment, it is possible to obtain the changes in material parameters of clothes before and after water absorption in the clothes treatment drum.

[0125] Optionally, in one embodiment of this application, in Figure 1 In S104 of the illustrated embodiment, or, in Figure 2 After S208 of the illustrated embodiment, the material of the clothing inside the clothing processing drum is determined in the following manner.

[0126] In this embodiment, the changes in parameter values ​​of different clothing materials before and after water absorption are described, including the range of changes in material parameter values ​​before and after water absorption. For example, the ranges of changes in material parameter values ​​before and after water absorption are as follows: Cotton: 20±d1; Linen: 15±d2; Silk: 10±d3; Wool: 30±d4; Polyester fiber: 45±d5; Synthetic fiber: 50±d6. According to the inventors' research and experiments, the values ​​of d1 to d6 can be obtained experimentally, and their specific values ​​are not specifically limited in this embodiment. Furthermore, their values ​​should not and cannot have overlapping ranges of changes in material parameter values ​​between the two clothing materials before and after water absorption.

[0127] In this embodiment, based on the correspondence between at least one material parameter change value and the change range of the material parameter values ​​of the various clothing materials before and after water absorption, the clothing material corresponding to the at least one material parameter change value is determined, and the clothing material in the clothing processing drum is obtained.

[0128] For example, regarding the material parameter changes |c1-a1|, |c2-a2|, and |c3-a3| mentioned earlier, the material of the garment in the garment treatment drum can be determined based on their correspondence with the range of changes in the material parameter values ​​of the garment before and after water absorption. For instance, assuming |c1-a1| = 20, |c2-a2| = 15, and |c3-a3| = 10, the garment materials can be determined to be cotton, linen, and silk, respectively.

[0129] Using this embodiment, the material of the clothing inside the clothing treatment drum can be accurately determined. It should be noted that, as mentioned above, a first reference parameter value and a second reference parameter value are used to represent a clothing material with a high probability, and the probability may fluctuate due to the influence of experimental and actual environments. However, this embodiment, by calculating the difference between the two states before and after water absorption, can effectively eliminate the interference of some environmental factors, thereby making the clothing material determined based on the change in material parameters highly accurate.

[0130] Optionally, in Figure 1 In the embodiment shown, the weight change of the clothes in the clothes treatment drum before and after absorbing water can be determined in the following way.

[0131] First, with the clothes dry, the dry weight (let's say ma) is obtained; then, the clothes are controlled to enter a water-absorbing state, and the wet weight (let's say mb) is obtained; then, the difference between the wet weight and the dry weight is calculated to obtain the weight change value. In this implementation, the method for weighing the clothes is described in existing technology and will not be elaborated here.

[0132] Using this embodiment, the weight change of clothing before and after absorbing water can be obtained, providing a data basis for subsequent weight assessment.

[0133] Optionally, in Figure 1 In S106 of the illustrated embodiment, the weight change pattern of different clothing materials before and after water absorption includes the amount of water absorbed per unit weight of the different clothing materials. The unit weight is preset, and the unit weight can be different for different clothing materials. For example, the clothing materials and their corresponding unit weights can be: cotton: 300g; linen: 200g; silk: 150g; wool: 800g; polyester fiber: 400g; synthetic fiber: 350g.

[0134] At this point, the weight of different clothing materials inside the clothing processing drum can be evaluated using the following methods.

[0135] First, based on the formula △m-k1≤M1*b1+M2*b2+……+Mn*bn≤△m+k1, determine b1, b2……bn that make the inequality true. Here, △m represents the weight change value, Mi represents the water absorption per unit weight of the i-th type of clothing material, bi represents the quantity per unit weight of the i-th type of clothing, n is a positive integer representing the type of clothing material; 1≤i≤n, bi is 0 or a positive integer with a corresponding value range, and k1 is a constant representing the allowable deviation range. The value of k1 can be determined experimentally or empirically; for example, k1∈(50g, 80g). For example, 0≤bi≤M / mi. Here, M represents the maximum total weight of clothing that the clothing processing equipment can hold, and mi represents the unit weight corresponding to the i-th type of clothing material.

[0136] Then, based on b1, b2...bn, and the unit weight of different clothing materials, estimate the weights of different clothing materials in the clothing processing tube: b1·m1, b2·m2,...bn·mn.

[0137] In this embodiment, taking the unit weight of cotton material as an example, its value can be set to 1 / 2, 1 / 3, 1 / 4 or 1 / 5 of the total weight of cotton clothing.

[0138] In this embodiment, we will use n=6, where n from 1 to 6 represents cotton, linen, silk, wool, polyester fiber, and chemical fiber, respectively, for illustration.

[0139] For example, after fully absorbing water, the weight per unit weight of each garment material is as follows: cotton: 450g; linen: 450g; silk: 200g; wool: 1150g; polyester: 600g; and synthetic fiber: 650g. The weight change (Mi) per unit weight of each garment material after fully absorbing water is as follows: cotton: 150g; linen: 250g; silk: 50g; wool: 350g; polyester: 200g; and synthetic fiber: 300g.

[0140] For example, in a specific testing process, in a 10 kg garment processing device, the garment materials were identified as linen, polyester fiber, and silk. When the weight difference between the garment before and after water absorption was detected to be 1550 g, based on the aforementioned formula and numerical examples, it can be determined that there are 4 units of linen, 2 units of polyester fiber, and 3 units of silk. Therefore, the weight of the linen garment can be determined to be 800 g, the weight of the polyester fiber garment to be 1200 g, and the weight of the silk garment to be 450 g.

[0141] Optionally, in one implementation, to more accurately assess the weight of different clothing materials within the clothing processing drum, b1, b2...bn can be calculated to simultaneously satisfy the following two inequalities. The weight corresponding to different clothing materials can then be calculated.

[0142] Inequality 1: △m-k1≤M1*b1+M2*b2+……+Mn*bn≤△m+k1. The explanations of the relevant parameters are provided above and will not be repeated here.

[0143] Inequality 2: ma-k2≤m1*b1+m2*b2+……+mn*bn≤ma+k2. Where ma represents the total weight of the clothes in the dry state, i.e., the weight of the dry clothes, k2 represents the allowable deviation of ma, for example, k2∈(40g, 60g), and mi(1≤i≤n) represents the unit weight of the i-th clothing material.

[0144] Figure 3 This is a schematic flowchart of a clothing processing method according to an embodiment of this application. (Refer to...) Figure 3 The following methods can be used to treat clothing.

[0145] S100: Determine the weight change of the clothes in the clothes treatment drum before and after water absorption.

[0146] S102: Determine the changes in material parameters of the clothes before and after water absorption in the clothes processing drum. The material parameters are determined based on the light signal collected by the light signal detection device, which is located inside the clothes processing drum and is used to collect the light signal after diffuse reflection of the incident light signal by the clothes.

[0147] S104: Determine the material of the clothing in the clothing treatment drum based on the changes in the material parameters and the changes in the parameter values ​​of different clothing materials before and after water absorption.

[0148] S106: Based on the clothing material in the clothing treatment drum, the weight change value, and the weight change pattern of different clothing materials before and after water absorption, evaluate the weight of different clothing materials in the clothing treatment drum.

[0149] For explanations regarding S100-S106, please refer to the previous text; they will not be repeated here.

[0150] S108: Based on the material of the clothing in the clothing processing tube and the weight of different clothing materials, the clothing is processed.

[0151] The clothing treatment method provided in this embodiment can be used to treat clothing according to its material and weight, thereby improving the targeting and effectiveness of clothing treatment.

[0152] Clothing processing includes traditional clothing processing procedures such as washing, drying, and atomizing.

[0153] For example, garment handling includes at least one of the following: selecting the weight of detergent, selecting the washing time, selecting the drying time, and selecting the washing mode.

[0154] The process of treating clothes based on their material and weight within the garment processing drum includes: if the weight of non-cleanable materials exceeds a set value, adding a set weight of detergent to the default detergent level, or adding a set washing time to the default washing time. Alternatively, if the weight of highly absorbent materials exceeds a set value, adding a set drying time to the default drying time. The terms "non-cleanable materials" and "highly absorbent materials" can be defined based on experience and experimentation. For example, cotton, linen, and wool can be defined as highly absorbent materials, while cotton and wool can be defined as non-cleanable materials.

[0155] For example, when the garment processing includes selecting a washing mode, the process of processing the garments based on the fabric type and weight of different fabric types in the garment processing drum includes: if there are fabric types in the garment processing drum whose weight percentage exceeds a set value, then during the first time period of the washing stage, a washing mode for fabric types whose weight percentage exceeds the set value is used, and during the second time period of the washing stage, a mixed washing mode is used. The first and second time periods together constitute the total washing stage time.

[0156] For example, if there are three types of clothing materials A, B, and C in the washing drum, and material A accounts for more than 50% of the total weight, then a washing mode suitable for washing material A should be used for the first half to three-quarters of the washing cycle, and a mixed washing mode should be used for the last quarter to half of the washing cycle. This improves the washing effect.

[0157] Optionally, in one embodiment of this application, the light signal can generate diffuse reflection after contacting the clothing, thereby obtaining the diffuse reflection parameter value.

[0158] Specifically, the diffuse reflection parameter value can be the parameter value of the reflected light signal itself after diffuse reflection, such as the wavelength and intensity of the reflected light signal, or it can be a parameter value obtained by calculating the parameter value of the reflected light signal itself, such as substituting the wavelength and / or intensity of the reflected light signal into a preset calculation formula to obtain the diffuse reflection parameter value. In general, it is sufficient as long as different clothing materials correspond to different diffuse reflection parameter values.

[0159] In one embodiment, the preset calculation formula for calculating the diffuse reflection parameter value can be a formula that includes the wavelength and intensity of the reflected light signal. For example, the diffuse reflection parameter value a = (wavelength λ - absorbed wavelength ΔE) / wavelength λ * φ luminous flux * power factor (intensity related).

[0160] In one embodiment, to determine the material of the clothing, a preset diffuse reflectance standard value range is established. Different diffuse reflectance standard value ranges correspond to different clothing materials; that is, there is a correspondence between the diffuse reflectance standard value range and the clothing material. Furthermore, the diffuse reflectance standard value range can also vary depending on the environment. For example, the same clothing material may correspond to different diffuse reflectance standard value ranges when the clothing is wet and dry.

[0161] Specifically, the diffuse reflectance standard value range is a numerical range composed of diffuse reflectance standard values. It's important to note that diffuse reflectance standard values ​​and diffuse reflectance parameter values ​​are of the same type or obtained using the same algorithm. The difference lies in that diffuse reflectance standard values ​​are parameter values ​​obtained by conducting diffuse reflectance experiments on clothing with known material characteristics, while diffuse reflectance parameter values ​​are parameter values ​​obtained by conducting diffuse reflectance experiments on clothing during actual material identification. For ease of understanding, for example, during testing, formula A is used to calculate the wavelength and intensity of the reflected light signal after diffuse reflection to obtain the diffuse reflectance standard value. After multiple tests on clothing of material 'a', a numerical range P1 can be defined based on all the obtained diffuse reflectance standard values. In actual clothing material identification, formula A is also used to calculate the wavelength and intensity of the reflected light signal after diffuse reflection, thus obtaining the diffuse reflectance parameter value. Since the calculation process for the diffuse reflectance parameter value is the same as that for the diffuse reflectance standard value, the clothing material can be determined based on the diffuse reflectance parameter value.

[0162] The correspondence between diffuse reflectance standard value ranges and clothing materials is as follows: each type of clothing material corresponds to a diffuse reflectance standard value range, and different types of clothing materials correspond to different diffuse reflectance standard value ranges. For example, material 'a' corresponds to the diffuse reflectance standard value range P1; this is the correspondence. Therefore, when the diffuse reflectance parameter value is within P1, it can be determined that the clothing material is 'a'.

[0163] This application also provides an electronic device, including a memory and a processor. The memory stores one or more computer instructions, and the processor executes the computer instructions to implement the clothing processing method described above.

[0164] This application also provides a garment processing device, which includes a controllable rotatable garment processing drum and a light signal detection device disposed inside the garment processing drum. The light signal detection device is located inside the garment processing drum and is used to collect the light signal after the garment diffusely reflects the incident light signal. The garment processing device employs the garment processing method provided in this application embodiment, or has the aforementioned electronic device.

[0165] Optionally, in one implementation of this embodiment, such as Figure 4 As shown, the garment processing tube is provided with at least one lifting rib 1, and a receiving groove 11 is provided in the at least one lifting rib 1, and the optical signal detection element 2 is located in the receiving groove 11.

[0166] The lifting rib 1 extends from the inner wall of the garment processing cylinder into the interior of the cylinder, and has a certain height. The lifting rib 1 can be integrally formed with the garment processing cylinder, or it can be connected to the inner wall of the garment processing cylinder by welding, screwing, or other methods. For ease of understanding, along the extension direction of the lifting rib 1, the surface of the lifting rib 1 closest to the center of the interior of the garment processing cylinder is the upper end surface of the lifting rib 1, and the receiving groove 11 is opened from the upper end surface towards the inner wall of the garment processing cylinder.

[0167] In this implementation, a receiving groove 11 is formed on the lifting rib 1 for mounting the optical signal detection element 2. This prevents the optical signal detection element 2 from becoming entangled with the clothes inside the clothes processing drum, thus minimizing its interference with the movement of the clothes. Simultaneously, the optical signal detection element 2, located within the lifting rib 1, can adjust its distance from the clothes according to the position of the lifting rib 1, thereby improving the detection accuracy and quality.

[0168] Optionally, in one implementation of this embodiment, the optical signal detection device 2 includes an emitter 21 and a receiver 22, which are arranged in parallel in the receiving groove 11. The emitter 21 is used to emit incident light signals into the clothing processing drum, and the receiver 22 is used to receive the reflected light signals after the clothing in the processing drum reflects the incident light signals.

[0169] Optionally, in one implementation of this embodiment, the emitter 21 and receiver 22 are arranged sequentially and parallel to each other along the rotation direction of the garment processing drum. There is a distance between the end faces of the emitter 21 and receiver 22 and the upper end face of the lifting rib 1. This distance is, for example, 20mm or 15mm; this implementation does not specifically limit this distance, but aims to improve the detection accuracy of the optical signal detection element 2 by setting this distance.

[0170] In this embodiment, the optical signal detection element 2 is installed at a distance, so that when the clothing covers the upper surface of the lifting rib 1, there will still be a distance between the clothing and the optical signal detection element 2, which helps to improve the detection quality of the optical signal detection element 2.

[0171] Optionally, in one implementation of this embodiment, the lifting rib 1 is provided with a cover plate for sealing the receiving groove 11. The cover plate is made of a waterproof and light-transmitting material. By using this implementation, the cover plate helps to seal the receiving groove 11, preventing water from the clothing processing drum from entering the receiving groove 11. This protects the optical signal detection element 2 from water ingress or immersion, thus improving the service life of the optical signal detection element 2.

[0172] Optionally, in one implementation of this embodiment, the optical signal detection device may include a first optical signal detection device and a second optical signal detection device with different wavelengths. Using two optical signal detection devices with different wavelengths can cover a wider range of clothing materials. For example, the first optical signal detection device is a second visible light sensor (e.g., an ultraviolet sensor) with a corresponding optical signal wavelength of 100-250nm, and the second optical signal detection device is a third visible light sensor (e.g., an ultraviolet sensor) with a corresponding optical signal wavelength of 290-400nm.
