It can perform such processing as washing, dehydrating, drying, and caring for clothing, which greatly improves the convenience of clothing processing. With the development of technology and the increase in user needs, the processing accuracy of clothing by clothing processing equipment has also improved. Taking washing machines as an example, current washing machines usually identify the material of clothing before processing it, so that different materials of clothing can use different processing parameters, which helps to improve the processing effect of clothing.

DETAILED DESCRIPTION

[0072] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0074] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0075] Clothes processing equipment is an indispensable device in daily life. It can perform such treatments as washing, dehydrating, drying, and caring for clothes, greatly improving the convenience of clothing processing. With the development of technology and the increase in user needs, the processing accuracy of clothes by clothing processing equipment has also improved. Taking washing machines as an example, current washing machines usually identify the material of clothes before processing them, so that clothes of different materials can use different processing parameters, which helps to improve the processing effect of clothes.

[0076] Material recognition methods include video recognition, which uses a camera to take a picture of the clothing and then uses an image algorithm to analyze the material of the clothing from the clothing image.

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

[0078] Based on this, the embodiment of the present application provides a clothing processing method, which can relatively accurately detect the clothing material. At the same time, it can also evaluate the weight of different clothing materials, and use the clothing material and corresponding weight as a reference for clothing processing, which is beneficial to improve the specificity of subsequent clothing processing and improve the effect of subsequent clothing processing.

[0079] Figure 1 is a schematic diagram of a process of a laundry treatment method according to an embodiment of the present application. Figure 1, the clothing treatment method includes the following treatment process.

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

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

[0082] S102: Determine the material parameter change value of the clothes in the clothes treatment drum before and after absorbing water. The material parameter is determined based on the light signal collected by the light signal detection component, which is located inside the clothes treatment drum and is used to collect the light signal after the clothes diffusely reflect the incident light signal.

[0083] In this embodiment, the material parameters of the clothes before absorbing water and the material parameters of the clothes after absorbing water can be detected, and then the difference calculation is performed to obtain the material parameter change value.

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

[0085] When identifying the material of clothing, the optical signal detection component emits an incident light signal to the clothing, and the incident light signal is diffusely reflected after contacting the clothing. In this embodiment, the optical signal detection component is used to obtain the light signal after diffuse reflection. The optical signal detection component or a processor corresponding to the optical signal detection component can convert the collected light signal into a specific numerical value for calculation, which is hereinafter referred to as a sampling value.

[0086] Optionally, in one implementation of this embodiment, when the clothes processing drum does not rotate (i.e., the state of the clothes in the clothes processing drum remains unchanged), an incident light signal is emitted toward the clothes through the light signal detection element, and a diffuse reflection light signal is received. This is repeated multiple times to obtain multiple sampling values ​​reflecting the light intensity or wavelength of the diffuse reflection light signal. Then, the above parameter value is calculated based on the multiple sampling values. The above parameter value can be an average value or median value of the multiple sampling values.

[0087] Afterwards, the laundry treatment drum can be rotated to change the laundry state, and then the laundry treatment drum is kept stationary, and the above process is repeated. This is repeated multiple times to obtain multiple parameter values ​​to cover all the laundry materials in the laundry treatment drum as much as possible.

[0088] S104: Determine the material of the clothes in the clothes processing drum according to the material parameter change value and the parameter value change pattern of different clothes materials before and after absorbing water.

[0089] The parameter value variation rules of the different clothing materials before and after absorbing water include the variation ranges of the material parameter values ​​of the different clothing materials before and after absorbing water. In other words, this embodiment can predetermine the variation range of the material parameter values ​​of each of the multiple clothing materials before and after absorbing water.

[0090] The variation range of the material parameter value of each clothing material before and after absorbing water is a numerical interval. When the clothing material is known, diffuse reflection experiments before and after absorbing water can be performed on the clothing, and statistics can be made and determined based on the obtained parameter values. According to the inventor's research and experimental findings, the variation range of the material parameter values ​​of different materials before and after absorbing water is different, so it can be used for material identification.

[0091] S106: Evaluate the weights of different clothing materials in the clothing processing drum according to the clothing materials in the clothing processing drum, the weight change values, and weight change patterns of different clothing materials before and after absorbing water.

[0092] By using the method provided in this embodiment, on the one hand, by determining the material parameter change value of the clothes in the clothes treatment drum before and after absorbing water, and determining the material of the clothes in the clothes treatment drum based on the material parameter change value and the parameter value change law of different clothes materials before and after absorbing water, the clothes material in the clothes treatment drum can be determined, thereby the clothes material can be determined more accurately; on the other hand, by determining the weight change value of the clothes in the clothes treatment drum before and after absorbing water, and based on the clothes material in the clothes treatment drum, the weight change value and the weight change law of different clothes materials before and after absorbing water, the weight of different clothes materials in the clothes treatment drum can be evaluated.

[0093] By adopting the method provided in this embodiment, the state of the clothes before and after absorbing water can be obtained through water intake and drainage, and the clothing material can be identified and the weight of different clothing materials can be evaluated at the same time through one water intake and drainage, which is beneficial to improving the targetedness of subsequent clothing treatment and improving the effect of clothing treatment.

[0094] Optionally, in an implementation of this embodiment, the following method may be used to make the clothes in the clothes treatment drum enter the clothes water absorption state.

[0095] First, water is poured into the laundry treatment drum until the laundry in the laundry treatment drum is completely submerged; then, the laundry is waited for to be completely submerged in water and to last for a set time (for example, 10 minutes, in order to allow the laundry to fully absorb water. The specific value can be determined based on experience or experiments, and is not described here); thereafter, after the laundry is completely submerged in water and to last for a set time, the water in the laundry treatment drum that is not absorbed by the laundry is drained, thereby obtaining the laundry water absorption state. In the laundry water absorption state, the laundry is in a state of fully absorbing water.

[0096] The water in the laundry treatment tub that is not absorbed by the laundry can be naturally drained by opening the drain valve and keeping the drain valve open for a set time, so as to ensure that the laundry is in a state of fully absorbing water.

[0097] By adopting this implementation method, clothes that fully absorb water can be obtained through water intake, water discharge and other processes.

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

[0099] Figure 2 1 is a flow chart of determining the material parameter change value of the clothes in the clothes treatment drum before and after absorbing water according to an embodiment of the present application. Figure 2 , the method includes the following processing.

[0100] S200: When the clothes are in a dry state, a plurality of first material parameter values ​​are obtained, and each of the first material parameter values ​​corresponds to a different state of the clothes.

[0101] Optionally, in an implementation of this embodiment, when the clothes are in a drying state, the clothes treatment drum is rotated a set number of times, and after each rotation of the clothes treatment drum, the optical signal detection component is controlled to emit the incident light signal and receive the light signal after diffuse reflection of the incident light signal through the optical signal detection component, and the first material parameter value corresponding to the current clothes state is determined according to the light signal received by the optical signal detection component. The purpose of the rotation set number of times is to enable the optical signal detection component to detect all clothes materials in the clothes treatment drum, and the value can be obtained based on experience and experiments, and can be 10 times, for example.

[0102] S202: When the clothing is in a water absorbing state, a plurality of second material parameter values ​​are obtained, wherein each of the second material parameter values ​​corresponds to a different clothing state.

[0103] Optionally, in an implementation of this embodiment, when the clothes are in the water absorbing state, the clothes treatment drum is rotated a set number of times, and after each rotation of the clothes treatment drum, the optical signal detection component is controlled to emit the incident light signal and receive the light signal after diffuse reflection of the incident light signal through the optical signal detection component, and the second material parameter value corresponding to the current clothes state is determined according to the light signal received by the optical signal detection component. The purpose of the rotation set number of times is to enable the optical signal detection component to detect all clothes materials in the clothes treatment drum, and the value can be obtained based on experience and experiments, and can be 10 times for example.

[0104] That is to say, in the embodiment of the present application, each first material parameter value / second material parameter value corresponds to a clothing state. The "clothing state" refers to the distribution state of the clothing in the clothing treatment drum (for example, the shape and area of ​​the clothing observed when looking down at the clothing treatment drum), and in the present application, it is assumed that as long as the clothing treatment drum rotates (for example, rotates more than one circle), the clothing state will change randomly, and the changed state will not recur. Without considering extreme situations and extremely small probabilities, this assumption conforms to the actual situation and can ensure the practicality of the present application solution.

[0105] S204: Determine at least one first parameter value for performing difference calculation according to the correspondence between the plurality of first material parameter values ​​and the first reference parameter value in the clothes dry state.

[0106] Each first reference parameter value corresponds to a clothing material. That is, a first reference parameter value is used to represent a clothing material with a high probability (that is, the corresponding clothing has a high probability of belonging to the clothing material).

[0107] Exemplarily, under a certain wavelength of incident light signal, 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: 130; Chemical fiber: 155. The first reference parameter values ​​of different clothing materials can be determined according to the diffuse reflection light signal collected by the optical signal detection component when the clothing is dry. For example, the ratio of the first reference parameter values ​​of different clothing materials can represent the ratio of the intensity (or wavelength) of the diffuse reflection light signal collected by the optical signal detection component for different clothing materials.

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

[0109] Optionally, in an implementation of this embodiment, at least one first parameter value for difference calculation is determined in the following manner: determine within which threshold range of the first reference parameter value the multiple first material parameter values ​​respectively fall, thereby establishing a mapping relationship between the multiple first material parameter values ​​and the multiple first reference parameter values, the number of the at least one first parameter value is the same as the number of first reference parameter values ​​mapped with the first material parameter value; for each first reference parameter value mapped with the first material parameter value, determine its corresponding first parameter value according to the first material parameter value mapped thereto, thereby obtaining the at least one first parameter value.

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

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

[0112] 120, 124, 110, 112-120 (silk);

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

[0114] Based on the above mapping relationships, the first parameter values ​​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 select one of the average value, median value, maximum value, and minimum value of the first material parameter values ​​(78, 81, 83) corresponding to the first reference parameter value (80, hemp), or directly select the first reference parameter value (80) 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 selection rules need to be the same before and after, and it is not possible to select the average value for the first mapping relationship and the median for the second day's mapping relationship.

[0115] For how to calculate the first parameter value for other mapping relationships, please refer to the above examples, which will not be described in detail here.

[0116] S206: Determine at least one second parameter value for difference calculation according to the correspondence between the plurality of second parameter values ​​and the second reference parameter value when the clothes absorb water.

[0117] Each second reference parameter value corresponds to a clothing material. That is, a second reference parameter value is used to represent a clothing material with a high probability (that is, the corresponding clothing has a high probability of belonging to the clothing material).

[0118] Exemplarily, under a certain wavelength of incident light signal, 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: 175; Chemical fiber: 205. The second reference parameter values ​​of different clothing materials can be determined according to the diffuse reflection light signal collected by the optical signal detection component when the clothing absorbs water. For example, the ratio of the second reference parameter values ​​of different clothing materials can represent the ratio of the intensity (or wavelength) of the diffuse reflection light signal collected by the optical signal detection component for different clothing materials.

[0119] Optionally, in an implementation of the present embodiment, the second benchmark parameter value in the water absorption state of the clothing includes multiple second benchmark parameter values ​​corresponding to multiple clothing materials, and each of the second benchmark parameter values ​​is set with a threshold range, which is similar in form to the threshold range of the first benchmark parameter value. The specific values ​​are not elaborated here.

[0120] Optionally, in an implementation of this embodiment, at least one second parameter value for difference calculation is determined in the following manner: determine within which threshold range of the second reference parameter value the multiple second material parameter values ​​respectively fall, thereby establishing a mapping relationship between the multiple second material parameter values ​​and the multiple second reference parameter values, the number of the at least one second parameter value is the same as the number of second reference parameter values ​​mapped with the second material parameter value; for each second reference parameter value mapped with the second material parameter value, determine its corresponding second parameter value according to the second material parameter value mapped thereto, thereby obtaining the at least one second parameter value.

[0121] For the specific method of determining the second parameter value, please refer to the method of determining the first parameter value in the previous article, which will not be repeated here.

[0122] S208: Calculate and obtain at least one material parameter change value according to the at least one second parameter value and the at least one first parameter value, wherein the at least one first parameter value, the at least one second parameter value and the at least one material parameter change value are the same in number.

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

[0124] By adopting the method provided in this embodiment, it is possible to obtain the material parameter change value of the clothes in the clothes treatment drum before and after absorbing water.

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

[0126] In this embodiment, the parameter value variation rules of different clothing materials before and after water absorption include the variation range of material parameter values ​​of different clothing materials before and after water absorption. Exemplarily, the variation range of material parameter values ​​of clothing materials before and after water absorption is as follows: cotton: 20±d1; linen: 15±d2; silk: 10±d3; wool: 30±d4; polyester fiber: 45±d5; chemical fiber: 50±d6. Among them, according to the research and experimental findings of the inventors, the values ​​of d1~d6 can be obtained according to experiments, and their specific values ​​are not specifically limited in the embodiments of this application, and their values ​​will not and cannot have the situation where the variation ranges of material parameter values ​​of two clothing materials before and after water absorption have overlapping intervals.

[0127] In this embodiment, based on the correspondence between at least one of the material parameter change values ​​and the change ranges of the material parameter values ​​of the multiple clothing materials before and after absorbing water, 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, for the material parameter change values ​​|c1-a1|, |c2-a2|, |c3-a3| mentioned above, the material of the clothes in the clothes treatment drum can be determined based on their corresponding relationship with the change range of the material parameter values ​​of the clothes before and after water absorption mentioned above. For example, assuming |c1-a1|=20, |c2-a2|=15, |c3-a3|=10, it can be determined that the clothes materials are cotton, linen, and silk, respectively.

[0129] By using this embodiment, the material of the clothes in the clothes treatment drum can be accurately determined. It should be noted that, as mentioned above, a first reference parameter value / a second reference parameter value is used to represent a type of clothing material with a high probability, and the probability fluctuates due to the influence of the experimental environment and the actual environment. However, in the embodiment of the present application, by calculating the difference between the two states before and after water absorption, the interference of some environmental factors can be effectively eliminated, so that the clothing material determined according to the material parameter change value has a higher accuracy.

[0130] Optionally, in Figure 1 In the illustrated embodiment, the weight change value of the clothes in the clothes treatment tub before and after absorbing water may be determined in the following manner.

[0131] First, in the drying state of the clothes, the weight of the dry clothes (assuming it is ma) is obtained; then, the clothes are controlled to enter the water absorbing state, and the weight of the wet clothes at this time (assuming it is mb) is obtained; then, the difference between the weight of the wet clothes and the weight of the dry clothes is calculated to obtain the weight change value. In this implementation, please refer to the prior art for how to weigh the clothes, which will not be described in detail here.

[0132] By adopting this embodiment, the weight change value of the clothes before and after absorbing water can be obtained, providing a data basis for subsequent weight evaluation.

[0133] Optionally, in Figure 1 In S106 of the illustrated embodiment, the weight change rules of different clothing materials before and after absorbing water include the water absorption corresponding to the unit weight of the different clothing materials. The unit weight is pre-set, and the unit weights corresponding to different clothing materials may be different. For example, the clothing materials and their corresponding unit weights may meet the following conditions: cotton: 300g; linen: 200g; silk: 150g; wool: 800g; polyester fiber: 400g; chemical fiber: 350g.

[0134] At this time, the weight of different clothing materials in the clothing processing tub may be evaluated in the following manner.

[0135] First, according to △m-k1≤M1*b1+M2*b2+……+Mn*bn≤△m+k1, determine b1, b2…bn that make the inequality hold, where △m represents the weight change value, Mi represents the water absorption per unit weight of the i-th clothing material, bi represents the number of unit weights contained in the i-th clothing, and n is a positive integer representing the type of clothing material; 1≤i≤n, bi is 0 or a positive integer and has a corresponding range of values, k1 is a constant representing the allowable deviation range, and the value of k1 can be determined based on experiments or experience, for example, k1∈(50g, 80g). Exemplarily, 0≤bi≤M / mi. Wherein, M represents the maximum total weight of clothing that the clothing processing device can accommodate, and mi represents the unit weight corresponding to the i-th clothing material.

[0136] Then, the weights b1·m1, b2·m2, ... bn·mn of the different clothing materials in the clothing treatment tub are estimated based on b1, b2, ... bn and the unit weights of the different clothing materials.

[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 ordinary cotton clothing.

[0138] In this embodiment, n is 6, and n from 1 to 6 represents cotton, linen, silk, wool, polyester fiber, and chemical fiber respectively.

[0139] For example, after fully absorbing water, the weight of each clothing material per unit weight satisfies: cotton: 450g; linen: 450g; silk: 200g; wool: 1150g; polyester fiber: 600g, chemical fiber: 650g. After fully absorbing water, the weight change value (Mi) of each clothing material per unit weight satisfies: cotton: 150g, linen: 250g, silk: 50g, wool: 350g, polyester fiber: 200g, chemical fiber: 300g.

[0140] For example, in a specific detection process, in a 10 kg class clothing processing device, it is determined that the materials of the clothing are linen, polyester fiber and silk. When the difference in weight of the clothing before and after water absorption is detected to be 1550g, it can be determined according to the above formula and numerical examples that there are 4 units of weight of linen, 2 units of weight of polyester fiber and 3 units of weight of silk. It can be further determined that the weight of the linen clothing is 800g, the weight of the polyester fiber clothing is 1200g, and the weight of the silk clothing is 450g.

[0141] Optionally, in one implementation, in order to more accurately evaluate the weight of different clothing materials in the clothing treatment drum, b1, b2, ..., bn that simultaneously satisfy the following two inequalities may be calculated, thereby calculating the weights corresponding to different clothing materials.

[0142] Inequality 1: △m-k1≤M1*b1+M2*b2+……+Mn*bn≤△m+k1. The explanation of the relevant parameters can be found in the previous text 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 a dry state, i.e., the weight of dry clothes, k2 represents the allowable deviation value 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 is a schematic diagram of a process of a laundry treatment method according to an embodiment of the present application. Figure 3 , the clothing treatment method includes the following treatments.

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

[0146] S102: Determine the material parameter change value of the clothes in the clothes treatment drum before and after absorbing water. The material parameter is determined based on the light signal collected by the light signal detection component, which is located inside the clothes treatment drum and is used to collect the light signal after the clothes diffusely reflect the incident light signal.

[0147] S104: Determine the material of the clothes in the clothes processing drum according to the material parameter change value and the parameter value change pattern of different clothes materials before and after absorbing water.

[0148] S106: Evaluate the weights of different clothing materials in the clothing processing drum according to the clothing materials in the clothing processing drum, the weight change values, and weight change patterns of different clothing materials before and after absorbing water.

[0149] For the description of S100-S106, please refer to the previous text and will not be repeated here.

[0150] S108: Processing the clothes according to the materials of the clothes in the clothes processing drum and the weights of the different clothes materials.

[0151] By adopting the clothing treatment method provided in this embodiment, clothing treatment can be performed according to the clothing material and the weight of different clothing materials, thereby improving the specificity of clothing treatment and the effect of clothing treatment.

[0152] Among them, clothing processing includes traditional clothing processing processes such as clothing washing, clothing drying, and clothing atomization.

[0153] Exemplarily, laundry treatment includes at least one of: selection of detergent weight, selection of washing time, selection of drying time, selection of washing mode.

[0154] The clothing treatment according to the clothing material in the clothing treatment drum and the weight of different clothing materials includes: if the weight of the difficult-to-clean material in the clothing treatment drum exceeds the set value, then the set weight of detergent is added on the basis of the default detergent weight, or the set washing time is added on the basis of the default washing time. Or, including: if the weight of the highly water-absorbent material in the clothing treatment drum exceeds the set value, then the set drying time is added on the basis of the default drying time. The difficult-to-clean material and the highly water-absorbent material can be defined based on experience and experiments. For example, cotton, linen, and wool materials are defined as highly water-absorbent materials, and cotton and wool materials are defined as difficult-to-clean materials, etc.

[0155] Exemplarily, in the case where the laundry treatment includes the selection of a washing mode, the laundry treatment is performed according to the laundry material in the laundry treatment drum and the weight of different laundry materials, including: if there are laundry materials in the laundry treatment drum whose weight ratio exceeds a set value, then in the first time period of the washing stage, a washing mode for the laundry materials whose weight ratio exceeds the set value is adopted, and in the second time period of the washing stage, a mixed washing mode is adopted. The combination of the first time period and the second time period is the total time of the washing stage.

[0156] For example, if there are three types of clothing materials A, B, and C in the clothing treatment drum, and the weight of one type of clothing material A accounts for more than 50%, the washing mode suitable for washing A is used in the first 1 / 2 to 3 / 4 of the washing stage, and the mixed washing mode is used in the last 1 / 4 to 1 / 2 of the washing stage, thereby improving the washing effect.

[0157] Optionally, in an embodiment of the present application, diffuse reflection may be generated after the light signal contacts the clothing, and then a diffuse reflection parameter value may be obtained.

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

[0159] In one embodiment, the preset calculation formula for calculating the diffuse reflection parameter value can be a formula including the wavelength and light intensity of the reflected light signal, for example, the diffuse reflection parameter value a = (wavelength λ-absorbed wavelength △E) / wavelength λ*φluminous flux*power factor (related to light intensity).

[0160] In one embodiment, in order to determine the material of the clothing, a diffuse reflection standard value interval is preset, and different diffuse reflection standard value intervals correspond to different clothing materials, that is, the diffuse reflection standard value intervals and clothing materials have a corresponding relationship. In addition, the diffuse reflection standard value intervals may also be different due to different environments. For example, when the clothing is in a water-absorbing and dry state, the same clothing material may correspond to different diffuse reflection standard value intervals.

[0161] Specifically, the diffuse reflection standard value interval is a numerical interval composed of diffuse reflection standard values. It should be noted that the diffuse reflection standard value and the diffuse reflection parameter value are of the same type or are obtained using the same algorithm. The difference is that the diffuse reflection standard value is a parameter value obtained by performing a diffuse reflection experiment on the clothing when the clothing material is known, while the diffuse reflection parameter value is a parameter value obtained by performing diffuse reflection on the clothing when the clothing material is actually identified. For ease of understanding, for example, during testing, the wavelength and light intensity of the reflected light signal after diffuse reflection are calculated using formula A to obtain the diffuse reflection standard value. After multiple tests on clothing of material a, a numerical interval P1 can be divided according to all the obtained diffuse reflection standard values. When actually identifying the clothing material, the wavelength and light intensity of the reflected light signal after diffuse reflection are also calculated using formula A to obtain the diffuse reflection parameter value. Since the calculation process of the diffuse reflection parameter value is the same as that of the diffuse reflection standard value, the clothing material of the clothing can be determined according to the diffuse reflection parameter value.

[0162] The corresponding relationship between the diffuse reflection standard value interval and the clothing material is: each type of clothing material corresponds to a diffuse reflection standard value interval, and different types of clothing materials correspond to different diffuse reflection standard value intervals. For example, material a corresponds to diffuse reflection standard value interval P1, which is the corresponding relationship. When the diffuse reflection parameter value is within P1, it can be determined that the clothing material of the clothing is a.

[0163] The embodiment of the present application further provides an electronic device, comprising a memory and a processor, wherein the memory stores one or more computer instructions, and the processor is used to execute the computer instructions to implement the above-mentioned clothing processing method.

[0164] The embodiment of the present application also provides a clothing processing device, which includes a clothing processing drum that can be controlled to rotate; and an optical signal detection component arranged inside the clothing processing drum. The optical signal detection component is located inside the clothing processing drum, and is used to collect the optical signal after the clothing diffusely reflects the incident optical signal. The clothing processing device adopts the clothing processing method provided in the embodiment of the present application, or has the above-mentioned electronic device.

[0165] Optionally, in an implementation of this embodiment, as Figure 4 As shown, at least one lifting rib 1 is provided on the laundry processing drum, 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 laundry treatment drum to the inside of the laundry treatment drum and has a certain height. The lifting rib 1 can be integrally formed with the laundry treatment drum, or can be connected to the inner wall of the laundry treatment drum by welding, screwing, etc. For ease of understanding, along the extension direction of the lifting rib 1, the surface of the lifting rib 1 close to the inner center of the laundry treatment drum is the upper end surface of the lifting rib 1, and the accommodating groove 11 is opened from the upper end surface toward the inner wall of the laundry treatment drum.

[0167] In this implementation, a receiving groove 11 is provided on the lifting rib 1 for installing the optical signal detection element 2, so that the optical signal detection element 2 is not easily entangled with the clothes in the clothes processing drum, and thus the optical signal detection element 2 is not easily affected by the movement of the clothes in the clothes processing drum. At the same time, the optical signal detection element 2 is located in the lifting rib 1, and can change the distance between it and the clothes as the position of the lifting rib 1 changes, which is conducive to improving the detection of the clothes by the optical signal detection element 2 and improving the detection quality.

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

[0169] Optionally, in an implementation of this embodiment, the emitter 21 and the receiver 22 are arranged in sequence and parallel to each other along the rotation direction of the laundry treatment drum. There is a distance between the end faces of the emitter 21 and the receiver 22 and the upper end face of the lifting rib 1. The distance is, for example, 20 mm or 15 mm, which is not specifically limited in this implementation, and is intended to improve the detection accuracy of the optical signal detection element 2 by setting the distance.

[0170] In this embodiment, the optical signal detector 2 is installed in a manner of setting a certain distance, so that when the clothes cover the upper end surface of the lifting rib 1, there is still a certain distance between the clothes and the optical signal detector 2, which helps to improve the detection quality of the optical signal detector 2.

[0171] Optionally, in an implementation of this embodiment, a cover plate for sealing the receiving groove 11 is provided on the lifting rib 1, and the cover plate is made of waterproof and light-transmitting material. In this implementation, by providing the cover plate, it is convenient to seal the receiving groove 11, so that the water in the clothes processing drum not only enters the receiving groove 11, but also protects the optical signal detection element 2 from being easily infiltrated or soaked by water, thereby improving the service life of the optical signal detection element 2.

[0172] Optionally, in one implementation of the present embodiment, the optical signal detection element may include a first optical signal detection element and a second optical signal detection element with different wavelengths. By using two optical signal detection elements with different wavelengths, a wider range of clothing materials can be covered. Exemplarily, the first optical signal detection element is a second visible light sensor (e.g., an ultraviolet sensor), and the corresponding optical signal wavelength is 100-250nm, and the second optical signal detection element is a third visible light sensor (e.g., an ultraviolet sensor), and the corresponding optical signal wavelength is 290-400nm.
