Description

Technical Field

[0001] This application relates to the field of material identification, and more specifically, to a method for identifying clothing materials, a control method for clothing processing equipment, and equipment. Background Technology

[0002] 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 washing machines typically perform detection actions before processing clothes, such as identifying the material and tangling status of the garments. This allows for the application of different processing parameters to clothes of different materials and with varying degrees of tangling, contributing to improved processing results.

[0003] The accuracy of current detection methods is often affected by a variety of factors, especially for light-based detection methods, which are easily affected by visible light shining into the processing tube, thus reducing the accuracy of the detection. Summary of the Invention

[0004] This application provides a method for identifying clothing materials, a control method for clothing processing equipment, and an equipment, to at least solve the technical problem of reduced detection accuracy of clothing.

[0005] According to a first aspect of the embodiments of this application, a method for identifying clothing material is provided, for identifying the clothing material in the processing drum of a clothing processing device, the method comprising:

[0006] The parameter values ​​characterizing the material of clothing are obtained and it is determined whether the parameter values ​​are within a preset range of clothing materials. The parameter values ​​are obtained based on an optical signal detection method.

[0007] If the parameter value is within the range of clothing materials, the material of the clothing in the processing drum is determined according to the parameter value and the correspondence between the clothing material range and the clothing material.

[0008] If the parameter value is not within the range of the clothing material, the light-blocking degree of the clothing processing equipment on the processing drum is adjusted, wherein different light-blocking degrees result in different light intensities entering the processing drum;

[0009] Reacquire the parameter values ​​representing the clothing material and determine whether the parameter values ​​are within the preset clothing material range.

[0010] In this embodiment, when detecting clothing material, different processing methods are adopted depending on whether the parameter value is within the clothing material range. When the parameter value is not within the clothing material range, the degree of light blocking of the processing tube is adjusted to reduce the influence of light inside the processing tube on the detection, thereby improving the detection accuracy.

[0011] In conjunction with the first aspect, in an optional implementation of this application embodiment, adjusting the light-blocking degree of the clothing processing device on the processing drum includes:

[0012] Based on the degree of deviation between the parameter value and the range of clothing materials, the degree of light blocking of the processing drum by the clothing processing equipment is adjusted;

[0013] The greater the degree of deviation, the greater the degree of light shading after adjustment.

[0014] Using this method, the degree of light blocking will vary depending on the degree of deviation, so that the degree of light blocking can be matched with the actual needs. This allows the parameter values ​​obtained after adjusting the degree of light blocking to more accurately reflect the material of the clothing and improve the detection accuracy.

[0015] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the method further includes:

[0016] The range of clothing materials whose parameter values ​​are closest to the target range is determined;

[0017] The smaller of the absolute value of the difference between the parameter value and the upper limit of the target interval and the absolute value of the difference between the parameter value and the lower limit of the target interval is taken as the deviation value between the parameter value and the target interval.

[0018] The degree of deviation is determined based on the deviation range in which the deviation value falls;

[0019] The clothing material range is preset to have multiple ranges, with different ranges corresponding to different clothing materials; the deviation range is preset to have multiple ranges, with different deviation ranges corresponding to different degrees of deviation.

[0020] Using this implementation method, since there are multiple types of clothing materials, there are also multiple clothing material ranges. When the parameter value does not fall within any clothing material range, the nearest clothing material range is determined as the target range, and then the deviation value is calculated to determine the degree of deviation. This helps to reduce the amount of calculation and improve the detection efficiency of clothing materials.

[0021] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the parameter value includes the average of multiple detection values ​​obtained in the optical signal detection method, and the detection value includes the value obtained by data conversion processing using the optical signal after diffuse reflection or transmission with the clothing.

[0022] This implementation method uses the average value as the parameter value, which helps to improve the detection accuracy.

[0023] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the method further includes:

[0024] When utilizing the diffuse reflection, the first wavelength and first luminous flux of the light signal prior to diffuse reflection with the clothing are obtained;

[0025] The detection value is calculated based on the second wavelength of the diffusely reflected light signal, the first wavelength, the first luminous flux, and the preset first power factor.

[0026] When utilizing the transmission, the first light intensity and the second light flux of the light signal before it is transmitted to the clothing are obtained;

[0027] The detection value is calculated based on the second light intensity, the first light intensity, the second luminous flux, and the preset second power factor of the transmitted light signal.

[0028] By adopting this implementation method, different optical signal utilization methods correspond to different detection value calculation methods, which helps to improve the accuracy of detection values. This allows the detection values ​​to more accurately reflect the detection status of clothing materials, thereby improving the accuracy of parameter values ​​in characterizing clothing materials and enhancing the precision of material detection.

[0029] In conjunction with the first aspect, in an optional implementation of this application embodiment, adjusting the light-blocking degree of the clothing processing device on the processing drum includes:

[0030] Obtain the light intensity value of the light entering the processing cylinder;

[0031] The degree of shading is adjusted according to the light intensity value.

[0032] Using this method, light intensity values ​​are easier to obtain, which helps improve the efficiency of clothing material detection and reduce costs.

[0033] In conjunction with the first aspect, in an optional implementation of this application embodiment, adjusting the degree of shading based on the light intensity value includes:

[0034] Determine the light intensity range in which the light intensity value is located, wherein there are multiple preset light intensity ranges, and different light intensity ranges correspond to different degrees of light blocking;

[0035] The degree of shading is adjusted to correspond to the degree of shading within the light intensity range where the light intensity value is located.

[0036] Using this implementation method, there are multiple light intensity ranges, which allows the degree of shading to be matched with actual needs. This makes the parameter values ​​obtained after adjusting the degree of shading more accurately reflect the material of the clothing and improve the detection accuracy.

[0037] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, an electro-atomization layer is provided on the observation window of the clothing processing device;

[0038] Adjusting the light-blocking degree of the garment processing equipment on the processing drum includes:

[0039] Adjust the atomization level of the electro-atomization layer to adjust the degree of light blocking.

[0040] Using this method, adjusting the degree of shading is simple and convenient, which helps to improve detection efficiency.

[0041] According to a second aspect of the present application, a control method for a garment processing device is provided, the method comprising:

[0042] The material of the clothing in the processing drum is identified using the clothing material identification method described above;

[0043] The clothing processing equipment is controlled to execute corresponding operating parameters based on the material.

[0044] In this embodiment, when the garment processing equipment is running, it will use the above-mentioned identification method to identify the material of the garment in the processing drum, and control the operating parameters according to the material, so that the garment processing equipment can use different operating parameters according to different garment materials, thereby improving the processing effect and efficiency of the garment processing equipment.

[0045] According to a third aspect of the embodiments of this application, a garment processing device is provided, comprising a processing cylinder and an observation window, wherein a light detection element is provided on the processing cylinder, and the light detection element is used to detect the material of the garment by means of diffuse reflection or transmission of light to obtain multiple detection values.

[0046] An electro-atomization layer is provided on the observation window, and the electro-atomization layer is configured with multiple atomization levels, with different atomization levels having different degrees of light blocking.

[0047] The garment processing device calculates parameter values ​​characterizing the garment material based on the multiple detection values ​​and uses the garment material identification method described above to identify the garment material.

[0048] The technical effects achieved by the third aspect are similar to those achieved by the corresponding technical means in the first aspect, and will not be elaborated further here. Attached Figure Description

[0050] Figure 2 This is a flowchart illustrating the determination of the degree of deviation in a clothing material identification method provided in this application embodiment. Detailed Implementation

[0051] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0052] 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.

[0053] 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.

[0054] First, the terminology used in the embodiments of this application will be introduced.

[0055] Frosted glass: This refers to glass with light-blocking capabilities. Its working principle is primarily based on electronic reaction and liquid crystal technology, using controlled electric current to switch between transparent and opaque states. This technology combines an electronically reactive coating and liquid crystal molecules, allowing a uniform frosted effect to form on the glass surface, thus achieving privacy protection and interior space partitioning. When an electric current stimulates the coating, the internal liquid molecules undergo a momentary change, forming gas and creating the frosted effect on the glass surface; when the current disappears, the liquid molecules quickly return to their original state, and the frosted effect disappears, achieving a controllable effect at any time.

[0056] 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 washing machines typically perform detection actions before processing clothes, such as identifying the material and tangling status of the garments. This allows for the application of different processing parameters to clothes of different materials and with varying degrees of tangling, contributing to improved processing results.

[0057] The accuracy of current detection methods is often affected by a variety of factors, especially for light-based detection methods, which are easily affected by visible light shining into the processing tube, thus reducing the accuracy of the detection.

[0058] Based on this, this application provides a method for identifying clothing material, used to identify the material of clothing in the processing drum of a clothing processing device, referring to... Figure 1 As shown, clothing material identification methods include:

[0059] S100: Obtain parameter values ​​that characterize the material of the clothing.

[0060] The parameter values ​​are obtained based on an optical signal detection method. It should be noted that the parameter values ​​only need to characterize the fabric material; this embodiment does not specifically limit the type or calculation process of the parameter values. For example, the parameter values ​​can be calculated based on the light intensity and wavelength during optical signal detection. Specifically, in one embodiment of this application, diffuse reflection occurs when the optical signal comes into contact with the fabric, thereby allowing the acquisition of diffuse reflection parameter values.

[0061] 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.

[0062] 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).

[0063] In one embodiment, in order to determine the material of clothing, a standard range of diffuse reflection values ​​is preset (corresponding to the clothing material range below). Different standard ranges of diffuse reflection values ​​correspond to different clothing materials. In other words, the standard range of diffuse reflection values ​​and the clothing material have a corresponding relationship.

[0064] 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.

[0065] 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 diffuse reflectance standard value range P1, which is the correspondence. This ensures that when the diffuse reflectance parameter value is within P1, the clothing material can be determined to be 'a'. Preferably, the correspondence obtained using an ultraviolet sensor and the formula includes: 100-130 corresponds to cotton, 135-155 to linen, 190-230 to wool, 165-189 to silk, 290-330 to polyester fiber, and 335-390 to synthetic fiber.

[0066] It should be noted that light signals can be transmitted when they come into contact with clothing. When light signals are transmitted after contact with clothing, transmission parameter values ​​can be obtained.

[0067] Specifically, transmission parameter values ​​can be the parameters of the transmitted light signal itself after transmission, such as the transmittance and intensity of the transmitted light signal, or they can be calculated from the parameters of the transmitted light signal itself, for example, by substituting the transmittance and / or intensity of the transmitted light signal into a preset calculation formula to obtain the transmission parameter values. In general, it is sufficient as long as different clothing materials correspond to different transmission parameter values.

[0068] In one embodiment, the preset calculation formula for calculating the transmission parameter value can be a formula that includes the wavelength and intensity of the transmitted light signal. For example, the transmission parameter value b = T% * φ luminous flux * power factor (intensity-related), and the transmittance T% = I (light intensity after transmission reduction) / IO (original light intensity) * 100%.

[0069] In one embodiment, in order to determine the material of clothing, a transmission standard value range is preset (corresponding to the clothing material range below). Different transmission standard value ranges correspond to different clothing materials. In other words, the transmission standard value range and the clothing material are all related.

[0070] Specifically, the transmission standard value range is a numerical range composed of transmission standard values. It's important to note that transmission standard values ​​and transmission parameter values ​​are of the same type or obtained using the same algorithm. The difference lies in that transmission standard values ​​are obtained by conducting transmission experiments on clothing with known material properties, while transmission parameter values ​​are obtained by conducting transmission experiments on clothing during actual material identification. For ease of understanding, for example, during testing, formula B is used to calculate the transmittance and intensity of the transmitted light signal to obtain the transmission standard value. After multiple tests on clothing of material b, a numerical range Q1 can be defined based on all the obtained transmission standard values. In actual clothing material identification, formula B is also used to calculate the transmittance and intensity of the transmitted light signal to obtain the transmission parameter value. Since the calculation process for the transmission parameter value is the same as that for the transmission standard value, the clothing material can be determined based on the transmission parameter value.

[0071] The correspondence between transmission standard value ranges and clothing materials is as follows: each type of clothing material corresponds to a transmission standard value range, and different types of clothing materials correspond to different transmission standard value ranges. For example, material 'a' corresponds to the transmission standard value range Q1, which is the correspondence. This ensures that when the transmission parameter value is within Q1, the clothing material can be determined to be 'a'. Preferably, the correspondence obtained using an ultraviolet sensor includes: 10-13 corresponds to cotton, 13.5-15.5 corresponds to linen, 19-23 corresponds to wool, 16.5-18.9 corresponds to silk, 29-33 corresponds to polyester fiber, and 33.5-39 corresponds to synthetic fiber.

[0072] S102. Determine whether the parameter value is within the preset range of clothing materials.

[0073] Different clothing materials have different material ranges. It should be noted that the material range should be set according to parameter values. That is, when determining the material range, the optical signal detection method is performed on clothing of known materials, and the material range of each clothing material is divided according to the parameter values ​​obtained by the optical signal detection method.

[0074] Furthermore, multiple clothing material ranges can be continuous or discontinuous. For discontinuous cases, for example, the range for cotton clothing is 100-130, and the range for linen clothing is 135-155. If the obtained parameter value is between 131 and 134, it is determined that it is not within the preset clothing material range.

[0075] S104. If the parameter value is within the range of clothing materials, the material of the clothing in the processing drum is determined according to the parameter value and the correspondence between the clothing material range and the clothing material.

[0076] Since each clothing material range is preset, each clothing material range has a corresponding relationship with the clothing material. For example, clothing material range 1 corresponds to linen, clothing material range 2 corresponds to cotton, and clothing material range 3 corresponds to fiber. If the parameter value is in clothing material range 3, then it is determined that the material of the clothing in the processing tube is fiber.

[0077] S106. If the parameter value is not within the range of clothing material, adjust the degree of light blocking of the processing drum by the clothing processing equipment.

[0078] The intensity of light entering the processing cylinder varies depending on the degree of light blocking.

[0079] Specifically, if the parameter value is not within any range of clothing materials, it proves that the light shining into the processing tube affects the accuracy of the optical signal detection. At this time, adjusting the degree of light blocking will reduce the intensity of the light entering the processing tube, thereby improving the accuracy of the optical signal detection and thus helping to identify the material of the clothing.

[0080] It should be noted that there are various ways to adjust the degree of light blocking, and this embodiment does not specifically limit this. For example, the intensity of light entering the processing cylinder can be blocked by controlling the movement of the light-blocking plate; another example is that the intensity of light entering the processing cylinder can be blocked by controlling the degree of fogging of the observation window of the clothing processing equipment.

[0081] S108. Reacquire the parameter values ​​representing the clothing material and determine whether the parameter values ​​are within the preset clothing material range.

[0082] After re-acquiring the parameter values, the re-acquiring parameter values ​​are used to determine whether they are within the range of clothing material. Steps S100-S108 are executed repeatedly until the clothing material is identified or the preset number of cycles is reached.

[0083] In this embodiment, when detecting clothing material, different processing methods are adopted depending on whether the parameter value is within the clothing material range. When the parameter value is not within the clothing material range, the degree of light blocking of the processing tube is adjusted to reduce the influence of light inside the processing tube on the detection, thereby improving the detection accuracy.

[0084] In one optional implementation of this application embodiment, adjusting the light-blocking degree of the garment processing device on the processing drum includes:

[0085] Adjust the degree of light blocking of the processing drum by the clothing processing equipment according to the deviation between the parameter values ​​and the range of clothing materials.

[0086] The greater the deviation, the greater the degree of shading after adjustment.

[0087] When the parameter value is not within any of the clothing material ranges, it will deviate from the clothing material range. The degree of deviation reflected by this deviation is used to adjust the light blocking level, so that the adjusted light blocking level will be different when the degree of deviation is different.

[0088] When multiple levels of light blocking are required, multiple light blocking panels can be added to the garment processing equipment. Each light blocking panel can reduce the light intensity to a limited extent. The higher the level of light blocking, the more light blocking panels are needed.

[0089] Using this method, the degree of light blocking will vary depending on the degree of deviation, so that the degree of light blocking can be matched with the actual needs. This allows the parameter values ​​obtained after adjusting the degree of light blocking to more accurately reflect the material of the clothing and improve the detection accuracy.

[0090] In one optional implementation of the embodiments of this application, such as Figure 2 As shown, the method also includes:

[0091] S200, Determine the target range as the range where the parameter value is closest to the clothing material range.

[0092] The target range can be determined by calculating the difference between the parameter value and each clothing material range. It should be noted that if the difference between the parameter value and two clothing material ranges is the same and the difference is the minimum difference, then both clothing material ranges are determined as the target range.

[0093] S202. The smaller of the absolute value of the difference between the parameter value and the upper limit of the target interval and the absolute value of the difference between the parameter value and the lower limit of the target interval shall be used as the deviation value between the parameter value and the target interval.

[0094] S204. Determine the degree of deviation based on the deviation range in which the deviation value falls.

[0095] There are multiple preset ranges for clothing materials, with different ranges corresponding to different clothing materials; there are also multiple preset deviation ranges, with different deviation ranges corresponding to different degrees of deviation.

[0096] Using this implementation method, since there are multiple types of clothing materials, there are also multiple clothing material ranges. When the parameter value does not fall within any clothing material range, the nearest clothing material range is determined as the target range, and then the deviation value is calculated to determine the degree of deviation. This helps to reduce the amount of calculation and improve the detection efficiency of clothing materials.

[0097] In one optional implementation of this application, the parameter value includes the average of multiple detection values ​​obtained in the optical signal detection method, and the detection value includes the value obtained by data conversion processing using the optical signal after diffuse reflection or transmission with clothing.

[0098] This implementation method uses the average value as the parameter value, which helps to improve the detection accuracy.

[0099] In one optional implementation of this application's embodiments, the method further includes:

[0100] When utilizing diffuse reflection, the first wavelength and first luminous flux of the light signal before diffuse reflection occurs with the clothing are obtained;

[0101] The detection value is calculated based on the second wavelength, first wavelength, first luminous flux, and preset first power factor of the diffusely reflected light signal.

[0102] Specifically, the detected value = (first wavelength λ - absorbed wavelength ΔE) / first wavelength λ * φ, first luminous flux * first power factor.

[0103] Wherein, the absorbed wavelength ΔE = first wavelength λ - second wavelength; the first power factor is related to the light intensity of the optical signal, that is, it is set according to the light intensity of the optical signal, and this embodiment does not make specific limitations on it.

[0104] When utilizing transmission, the first light intensity and the second light flux of the light signal before it is transmitted to the clothing are obtained.

[0105] The detection value is calculated based on the second light intensity, the first light intensity, the second luminous flux, and the preset second power factor of the transmitted light signal.

[0106] Specifically, the detected value = T% * φ (second luminous flux) * second power factor.

[0107] Wherein, transmittance T% = second light intensity I / first light intensity IO * 100%; the second power factor is related to the light intensity of the light signal, that is, it is set according to the light intensity of the light signal, and this embodiment does not make specific limitations on it.

[0108] By adopting this implementation method, different optical signal utilization methods correspond to different detection value calculation methods, which helps to improve the accuracy of detection values. This allows the detection values ​​to more accurately reflect the detection status of clothing materials, thereby improving the accuracy of parameter values ​​in characterizing clothing materials and enhancing the precision of material detection.

[0109] In one optional implementation of this application embodiment, adjusting the light-blocking degree of the garment processing device on the processing drum includes:

[0110] Obtain the light intensity value of the light entering the processing cylinder;

[0111] Adjust the degree of shading according to the light intensity value.

[0112] The light intensity value can be detected using devices such as light intensity sensors, and this embodiment does not impose specific limitations on it.

[0113] Using this method, light intensity values ​​are easier to obtain, which helps improve the efficiency of clothing material detection and reduce costs.

[0114] In one optional implementation of this application embodiment, adjusting the degree of shading based on the light intensity value includes:

[0115] Determine the light intensity range in which the light intensity value falls.

[0116] There are multiple preset light intensity ranges, and different light intensity ranges correspond to different degrees of shading.

[0117] Adjust the shading level to correspond to the shading level within the light intensity range where the light intensity value is located.

[0118] Specifically, the higher the light intensity value, the stronger the shading should be.

[0119] Using this implementation method, there are multiple light intensity ranges, which allows the degree of shading to be matched with actual needs. This makes the parameter values ​​obtained after adjusting the degree of shading more accurately reflect the material of the clothing and improve the detection accuracy.

[0120] In one optional implementation of this application embodiment, an electro-atomization layer is provided on the observation window of the clothing processing device;

[0121] Adjusting the light-blocking level of the garment processing equipment for the processing drum, including:

[0122] Adjust the atomization level of the electro-atomization layer to adjust the degree of light blocking.

[0123] Using this method, adjusting the degree of shading is simple and convenient, which helps to improve detection efficiency.

[0124] According to a second aspect of the embodiments of this application, a control method for a garment processing device is provided, the method comprising:

[0125] The material of the clothing in the processing drum is identified using the above-described clothing material identification method;

[0126] The operating parameters of the garment processing equipment are controlled according to the material.

[0127] In this embodiment, when the garment processing equipment is running, it will use the above-mentioned identification method to identify the material of the garment in the processing drum, and control the operating parameters according to the material, so that the garment processing equipment can use different operating parameters according to different garment materials, thereby improving the processing effect and efficiency of the garment processing equipment.

[0128] According to a third aspect of the embodiments of this application, a garment processing device is provided, comprising a processing cylinder and an observation window. A light detection element is provided on the processing cylinder, and the light detection element is used to detect the material of the garment by means of diffuse reflection or transmission of light, so as to obtain multiple detection values.

[0129] An electro-atomization layer is provided on the observation window, and the electro-atomization layer is configured with multiple atomization levels, with different atomization levels having different degrees of light blocking;

[0130] The garment processing equipment calculates parameter values ​​characterizing the garment material based on multiple detection values ​​and uses the aforementioned garment material identification method to identify the garment material.

[0131] In the above embodiments of this application, the descriptions of each embodiment have their own emphasis. Parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments. The steps illustrated in the related flowcharts can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown here. In other words, the order of steps described in the foregoing embodiments is merely an example. Reasonable adjustments to the order of steps based on the content of the embodiments of this application are also within the protection scope of the embodiments of this application.

[0132] In one specific implementation of this application embodiment, material identification includes the following processing steps:

[0133] The ultraviolet (UV) sensor is installed flat inside the lifting ribs. Its function is to detect the material of the clothing inside the drum using diffuse reflection. A photosensitive sensor is installed on the door to detect the intensity of visible light transmitted into the drum. To avoid interference from UV light inside the drum, a visible light photosensitive sensor is preferred. The viewing window is also equipped with an electro-fogging function, allowing for adjustable levels of blur. The electro-fogging glass can be installed anywhere between the viewing window and the photosensitive sensor; its preferred location is at the viewing window for easier electro-fogging and detection of incoming light intensity.

[0134] Parameter description:

[0135] The ultraviolet spectrum used in this application has a wavelength of 10-400 nm, and the wavelength of absorption is calculated according to quantum theory as ΔE = hv = hc / λ. The visible light spectrum has a wavelength of 400-760 nm, so the intensity of visible light incident into the processing tube is not affected by the ultraviolet light inside the processing tube when detecting the intensity of visible light incident into the processing tube.

[0136] Control methods:

[0137] After clothing is placed into the processing drum, the main control board detects the current and power of the drive motor to determine the weight of the clothing. Once clothing is confirmed, the ultraviolet sensor on the lifting rib begins to detect the material of the clothing. Through diffuse reflection, it detects the corresponding parameter value 'a' (the average value after multiple samplings) of the clothing in the processing drum. After conversion, it compares this value with the preset value on the main board (i.e., the clothing material range) to determine if 'a' is within the clothing material range. If it is, the ultraviolet sensor on the lifting rib detects the clothing material normally. If the detected parameter 'a' is not within the clothing material range, the visible light sensor detects the light intensity 'β' at this time to obtain the current light intensity 'β'. Because visible light has a certain influence on ultraviolet light, resulting in a reduction in the number of detected values, an ultraviolet sensor is used to detect the material of the clothing. The parameter value 'a' (the average value after multiple acquisitions) is calculated using the detected values. Then, it is determined whether the newly calculated 'a' deviates from the clothing material range by ±10. If there is no deviation and 'a' is within the clothing material range, the ultraviolet sensor in the lifting rib can normally detect the material of the tubular clothing. If there is a deviation and the deviation is within ±10, the main board sends a signal to the observation window to perform electro-fogging treatment on the glass of the observation window. The electro-fogging treatment is divided into 5 levels, from level 1 to level 5, from low to high. Level 1 has low ambiguity and low light blocking, while level 5 has the highest ambiguity and highest light blocking, which can basically completely block external light sources. Since the material testing parameters are within ±10, the observation window is fogged according to the first level of electro-fogging. If the deviation is within ±20, the observation window is fogged according to the second level of electro-fogging. The highest level of fogging is the fifth level, which is complete fogging and can basically completely block external light sources.

[0138] After each atomization cycle, a visible light sensor is used to detect the light intensity β after the visible light penetrates the processing cylinder through the observation window. Each level of electro-atomization corresponds to a light intensity β1-β5 after shielding. β1-β2 represents light atomization, suitable for material identification parameter a within ±20 deviations from the closest clothing material range. β3-β4 represents moderate atomization, with the cylinder essentially in darkness, where visible light has a lower impact on the ultraviolet sensor. β5 represents full atomization, completely atomizing the observation window, suitable for detecting materials where the material identification parameter a is close to polyester fiber within ±35. This material has a larger detection range and is more affected by visible light.

[0139] After adjusting the UV sensor to the appropriate level of atomization for the material being detected, the visible light β intensity is measured to determine if the atomization effect is suitable. The UV sensor then begins to detect the clothing inside the tube, taking multiple samples and calculating the average value. This average value is then compared with the preset value to identify the material.

[0140] For example, if the detection range 'a' is close to the Δa range of polyester fibers and within ±35 of the range's deviation, the mainboard does not need to detect the light intensity at this time because it is close to the polyester fiber material. In this case, an electro-atomization step is necessary. The observation window is adjusted to level 5. The visible light sensor confirms that the visible light intensity inside the drum is β5, indicating near-complete darkness inside the drum. The mainboard then controls the ultraviolet light to detect the material of the clothes inside the drum. The detection value should fall within the preset range for polyester fibers. Atomization of the observation window ensures accurate detection by the ultraviolet sensor. After determining the material, the water flow, rinsing cycles, and spin speed are adjusted to suit the polyester fiber washing parameters for optimal washing results.
