Technical Field

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

[0002] Clothes processing equipment is an indispensable device in daily life. It can perform such processing 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 perform some detection actions before processing clothes, such as identifying the material of clothes, the entanglement of clothes, etc., so that clothes of different materials and entanglement can use different processing parameters, which helps to improve the processing effect of clothes.

[0003] However, the detection accuracy of current detection actions is often affected by many factors. In particular, the detection method using light is easily affected by the visible light shining into the processing tube, which reduces the detection accuracy. Summary of the invention

[0004] The embodiments of the present application provide a method for identifying clothing materials, a control method and a device for clothing processing equipment, so as to at least solve the technical problem of reduced detection accuracy of clothing.

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

[0006] Obtaining a parameter value representing a material of clothing and determining whether the parameter value is within a preset clothing material range, wherein the parameter value is obtained based on an optical signal detection method;

[0007] If the parameter value is within the clothing material range, determining the material of the clothing in the processing drum according to the parameter value and the corresponding relationship between the clothing material range and the clothing material;

[0008] If the parameter value is not within the clothing material range, adjusting the degree of light shielding of the processing drum by the clothing processing device, wherein different degrees of light shielding result in different intensities of light entering the processing drum;

[0009] The parameter value representing the clothing material is reacquired and it is determined whether the parameter value is within a preset clothing material range.

[0010] With this embodiment, when detecting clothing material, different processing methods will be adopted according to whether the parameter value is within the clothing material range, and when the parameter value is not within the clothing material range, the degree of shading of the processing drum will be adjusted to reduce the influence of the light in the processing drum on the detection, thereby improving the detection accuracy.

[0011] In combination with the first aspect, in an optional implementation of the embodiment of the present application, adjusting the degree of light shielding of the processing drum by the clothes processing device includes:

[0012] According to the degree of deviation between the parameter value and the clothing material range, adjusting the degree of shading of the processing drum by the clothing processing device;

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

[0014] By adopting this implementation method, the degree of deviation is different, and the adjusted shading degree is also different, so that the shading degree can be matched with actual needs, so that the parameter value obtained after adjusting the shading degree can more accurately reflect the material of the clothing and improve the detection accuracy.

[0015] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0016] Determine the clothing material interval closest to the parameter value as the target interval;

[0017] The smaller one 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 used as the deviation value between the parameter value and the target interval;

[0019] There are multiple preset clothing material intervals, and different clothing material intervals correspond to different clothing materials; there are multiple preset deviation intervals, and different deviation intervals correspond to different deviation degrees.

[0020] With this implementation method, since there are multiple types of clothing materials, there are also multiple clothing material intervals. When the parameter value is not in any clothing material interval, the nearest clothing material interval is determined as the target interval, and then the deviation value is calculated to determine the degree of deviation, which is conducive to reducing the amount of calculation and improving the detection efficiency of clothing materials.

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

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

[0028] By adopting this implementation method, different light signal utilization methods correspond to different detection value calculation methods, which helps to improve the accuracy of the detection value, so that the detection value can more accurately reflect the detection situation of the clothing material, thereby improving the accuracy of the parameter value in representing the clothing material and improving the accuracy of material detection.

[0029] In combination with the first aspect, in an optional implementation of the embodiment of the present application, adjusting the degree of light shielding of the processing drum by the clothes processing device includes:

[0030] Acquiring the light intensity value of the light entering the processing tube;

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

[0032] By adopting this implementation method, the light intensity value is easy to obtain, which helps to improve the efficiency of clothing material detection and reduce costs.

[0033] In combination with the first aspect, in an optional implementation of the embodiment of the present application, adjusting the shading degree according to the light intensity value includes:

[0034] Determine the light intensity interval in which the light intensity value is located, wherein a plurality of light intensity intervals are preset, and different light intensity intervals correspond to different degrees of shading;

[0035] The shading degree is adjusted to a shading degree corresponding to the light intensity interval in which the light intensity value is located.

[0036] With this implementation, there are multiple light intensity intervals, so that the shading degree can be matched with actual needs, so that the parameter value obtained after adjusting the shading degree can more accurately reflect the material of the clothing, thereby improving the detection accuracy.

[0037] In combination with the first aspect, in an optional implementation of the embodiment of the present application, an electrospray layer is provided on the observation window of the clothing processing device;

[0038] The step of adjusting the degree of light shielding of the processing drum by the laundry processing device comprises:

[0039] The atomization level of the electro-atomization layer is adjusted to adjust the degree of shading.

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

[0041] According to a second aspect of an embodiment of the present application, a method for controlling a laundry processing device is provided, the method comprising:

[0042] The material of the clothes in the treatment drum is identified by using the above-mentioned clothing material identification method;

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

[0044] With this embodiment, when the clothing processing device is in operation, the above-mentioned identification method will be used to identify the material of the clothing in the processing drum, and the operating parameters will be controlled according to the material, so that the clothing processing device can use different operating parameters due to different clothing materials, thereby improving the clothing processing effect and efficiency of the clothing processing device.

[0051] 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.

[0052] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; the "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. 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

[0053] 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.

[0054] First, the terms involved in the embodiments of the present application are introduced.

[0055] Atomized glass: refers to glass with shading ability. The working principle is mainly based on electronic reaction and liquid crystal technology. The glass can be switched between transparent and opaque by controlling the electric current. This technology combines electronic reaction coating and liquid crystal molecules, so that the glass surface can form a uniform atomization effect, thereby achieving the functions of privacy protection and indoor space separation. When the current stimulates the coating, the internal liquid molecules will change instantly and form gas, causing the glass surface to have an atomization effect; when the current disappears, the liquid molecules quickly return to their original state, and the atomization effect disappears, achieving an effect that can be controlled at any time.

[0056] Clothes processing equipment is an indispensable device in daily life. It can perform such processing 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 perform some detection actions before processing clothes, such as identifying the material of clothes, the entanglement of clothes, etc., so that clothes of different materials and entanglement can use different processing parameters, which helps to improve the processing effect of clothes.

[0057] However, the detection accuracy of current detection actions is often affected by many factors. In particular, the detection method using light is easily affected by the visible light shining into the processing tube, which reduces the detection accuracy.

[0058] Based on this, the embodiment of the present application provides a method for identifying the material of clothing used to identify the material of clothing in a processing drum of a clothing processing device. Figure 1 As shown, the clothing material recognition method includes:

[0059] S100: Obtain parameter values ​​representing clothing material.

[0060] The parameter value is obtained based on the optical signal detection method. It should be noted that as long as the parameter value can characterize the material of the clothing, this embodiment does not specifically limit the type of parameter value and the calculation process. For example, the parameter value can be calculated based on the light intensity, wavelength, etc. during optical signal detection. Specifically, in one embodiment of the present application, diffuse reflection can be generated after the optical signal contacts the clothing, and then the diffuse reflection parameter value can be obtained.

[0061] 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.

[0062] 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).

[0063] In one embodiment, in order to determine the material of clothing, a diffuse reflection standard value interval is preset (corresponding to the clothing material interval below), and different diffuse reflection standard value intervals correspond to different clothing materials, that is, the diffuse reflection standard value interval has a corresponding relationship with the clothing material.

[0064] 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.

[0065] The correspondence 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 the diffuse reflection standard value interval P1, which is the correspondence. So that when the diffuse reflection parameter value is within P1, it can be determined that the clothing material of the clothing is a. Preferably, the correspondence obtained by testing with an ultraviolet sensor and using the formula includes: the material tested at 100-130 is cotton, the material tested at 135-155 is linen, the material corresponding to 190-230 is wool, the material corresponding to 165-189 is silk, the material corresponding to 290-330 is polyester fiber, and the material corresponding to 335-390 is chemical fiber.

[0066] It should be noted that the light signal may be transmitted after contacting the clothing, wherein when the light signal is transmitted after contacting the clothing, a transmission parameter value may be obtained.

[0067] Specifically, the transmission parameter value may be a parameter value of the transmission light signal itself after transmission occurs, such as the transmittance, light intensity, etc. of the transmission light signal, or may be a parameter value obtained after calculating the parameter value of the transmission light signal itself, such as substituting the transmittance and / or light intensity of the transmission light signal into a preset calculation formula to obtain the transmission parameter value. In general, as long as different clothing materials can correspond to different transmission parameter values.

[0068] In one embodiment, the preset calculation formula for calculating the transmission parameter value may be a formula including the wavelength and light intensity of the transmitted light signal, for example, the transmission parameter value b=T%*φluminous flux*power factor (related to light intensity), and the transmittance T%=I(light intensity after transmission attenuation) / IO(original light intensity)*100%.

[0069] In one embodiment, in order to determine the material of clothing, a transmission standard value interval is preset (corresponding to the clothing material interval below), and different transmission standard value intervals correspond to different clothing materials, that is, there is a corresponding relationship between the transmission standard value interval and the clothing material.

[0070] Specifically, the transmission standard value interval is a numerical interval composed of transmission standard values. It should be noted that the transmission standard value and the transmission parameter value are of the same type or are obtained using the same algorithm. The difference is that the transmission standard value is a parameter value obtained by performing a transmission experiment on the clothing when the clothing material is known, while the transmission parameter value is a parameter value obtained by transmitting the clothing when the clothing material is actually identified. For ease of understanding, for example, during the test, the transmittance and light intensity of the transmitted light signal are calculated using formula B to obtain the transmission standard value. After multiple tests on clothing of material b, a numerical interval Q1 can be divided according to all the obtained transmission standard values. When the clothing material is actually identified, the transmittance and light intensity of the transmitted light signal are also calculated using formula B to obtain the transmission parameter value. Since the calculation process of the transmission parameter value is the same as that of the transmission standard value, the clothing material of the clothing can be determined according to the transmission parameter value.

[0071] The corresponding relationship between the transmission standard value interval and the clothing material is: each type of clothing material corresponds to a transmission standard value interval, and different types of clothing materials correspond to different transmission standard value intervals. For example, material a corresponds to the transmission standard value interval Q1, which is the corresponding relationship. When the transmission parameter value is within Q1, it can be determined that the clothing material of the clothing is a. Preferably, the corresponding relationship obtained by testing with an ultraviolet sensor includes: the material tested at 10-13 is cotton, the material tested at 13.5-15.5 is linen, the material corresponding to 19-23 is wool, the material corresponding to 16.5-18.9 is silk, the material corresponding to 29-33 is polyester fiber, and the material corresponding to 33.5-39 is chemical fiber.

[0072] S102: Determine whether the parameter value is within a preset clothing material range.

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

[0074] In addition, the multiple clothing material intervals may be continuous or discontinuous. For the discontinuous case, for example, the cotton clothing material interval is 100-130, and the linen clothing material interval is 135-155. If the obtained parameter value is between 131-134, it is determined that it is not within the preset clothing material interval.

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

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

[0077] S106: If the parameter value is not within the clothing material range, adjust the degree of shading of the processing drum by the clothing processing device.

[0078] Among them, the light intensity of the light entering the treatment tube is different due to the different degree of shading.

[0079] Specifically, the parameter value is not within any range of clothing materials, which proves that the light irradiated into the processing drum affects the accuracy of light signal detection. At this time, adjusting the degree of shading to weaken the intensity of light entering the processing drum can improve the accuracy of light signal detection, which is conducive to identifying the material of clothing.

[0080] It should be noted that there are many ways to adjust the degree of shading, which are not specifically limited in this embodiment. For example, by controlling the movement of the shading plate, the light intensity of the light entering the treatment drum is blocked, and for another example, by controlling the degree of atomization of the observation window of the clothes processing device, the light intensity of the light entering the treatment drum is blocked.

[0081] S108, reacquiring the parameter value representing the clothing material and determining whether the parameter value is within a preset clothing material range.

[0082] After the parameter value is re-acquired, the re-acquired parameter value is used to determine whether it is within the clothing material range, thereby looping through steps S100-S108 until the clothing material is identified or a preset number of cycles is reached.

[0083] With this embodiment, when detecting clothing material, different processing methods will be adopted according to whether the parameter value is within the clothing material range, and when the parameter value is not within the clothing material range, the degree of shading of the processing drum will be adjusted to reduce the influence of the light in the processing drum on the detection, thereby improving the detection accuracy.

[0084] In an optional implementation of the embodiment of the present application, adjusting the degree of light shielding of the processing drum by the clothes processing device includes:

[0085] According to the degree of deviation between the parameter value and the clothing material range, the degree of shading of the processing drum by the clothing processing device is adjusted.

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

[0087] When the parameter value is not in any clothing material range, it will deviate from the clothing material range. The degree of deviation reflected by the deviation is used to adjust the shading degree, so that when the deviation degree is different, the adjusted shading degree is also different.

[0088] When multiple shading levels are required, multiple shading plates can be added to the clothing processing device. Each shading plate can reduce a limited amount of light intensity. The higher the shading level, the more shading plates are needed for shading.

[0089] By adopting this implementation method, the degree of deviation is different, and the adjusted shading degree is also different, so that the shading degree can be matched with actual needs, so that the parameter value obtained after adjusting the shading degree can more accurately reflect the material of the clothing and improve the detection accuracy.

[0090] In an optional implementation of the embodiment of the present application, Figure 2 As shown, the method also includes:

[0091] S200: Determine the clothing material interval with the closest parameter value as the target interval.

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

[0093] S202: The smaller one 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 used as the deviation value between the parameter value and the target interval.

[0094] S204: Determine the degree of deviation according to the deviation interval in which the deviation value is located.

[0095] There are multiple preset clothing material intervals, and different clothing material intervals correspond to different clothing materials; there are multiple preset deviation intervals, and different deviation intervals correspond to different deviation degrees.

[0096] With this implementation method, since there are multiple types of clothing materials, there are also multiple clothing material intervals. When the parameter value is not in any clothing material interval, the nearest clothing material interval is determined as the target interval, and then the deviation value is calculated to determine the degree of deviation, which is conducive to reducing the amount of calculation and improving the detection efficiency of clothing materials.

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

[0098] By adopting this implementation method, the average value is used as the parameter value, which is conducive to improving the detection accuracy.

[0099] In an optional implementation of the embodiment of the present application, the method further includes:

[0100] When diffuse reflection is used, obtaining a first wavelength and a first luminous flux of the light signal before diffuse reflection occurs on the clothing;

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

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

[0103] The absorbed wavelength ΔE=the first wavelength λ-the 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, which is not specifically limited in this embodiment.

[0104] When utilizing transmission, obtaining a first light intensity and a second light flux of the light signal before transmission with the clothing occurs;

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

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

[0107] Wherein, the transmittance T%=second light intensity I / first light intensity IO*100%; the second 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, which is not specifically limited in this embodiment.

[0108] By adopting this implementation method, different light signal utilization methods correspond to different detection value calculation methods, which helps to improve the accuracy of the detection value, so that the detection value can more accurately reflect the detection situation of the clothing material, thereby improving the accuracy of the parameter value in representing the clothing material and improving the accuracy of material detection.

[0109] In an optional implementation of the embodiment of the present application, adjusting the degree of light shielding of the processing drum by the clothes processing device includes:

[0110] Obtaining the light intensity value of the light entering the treatment tube;

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

[0112] The light intensity value may be detected using a light intensity sensor or other equipment, which is not specifically limited in this embodiment.

[0113] By adopting this implementation method, the light intensity value is easy to obtain, which helps to improve the efficiency of clothing material detection and reduce costs.

[0114] In an optional implementation of the embodiment of the present application, adjusting the degree of shading according to the light intensity value includes:

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

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

[0117] The shading degree is adjusted to a shading degree corresponding to the light intensity interval in which the light intensity value lies.

[0118] Specifically, the higher the light intensity value, the stronger the shading degree is selected.

[0119] With this implementation, there are multiple light intensity intervals, so that the shading degree can be matched with actual needs, so that the parameter value obtained after adjusting the shading degree can more accurately reflect the material of the clothing, thereby improving the detection accuracy.

[0120] In an optional implementation of the embodiment of the present application, an electrospray layer is provided on the observation window of the clothing processing device;

[0121] Adjust the degree of light shielding of the laundry treatment equipment to the treatment drum, including:

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

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

[0124] According to a second aspect of an embodiment of the present application, a method for controlling a laundry processing device is provided, the method comprising:

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

[0126] The clothing processing equipment is controlled to execute corresponding operating parameters according to the material.

[0127] With this embodiment, when the clothing processing device is in operation, the above-mentioned identification method will be used to identify the material of the clothing in the processing drum, and the operating parameters will be controlled according to the material, so that the clothing processing device can use different operating parameters due to different clothing materials, thereby improving the clothing processing effect and efficiency of the clothing processing device.

[0128] According to a third aspect of an embodiment of the present application, there is provided a clothing processing device, comprising a processing drum and an observation window, wherein a light detection element is provided on the processing drum, and the light detection element is used to detect the material of the clothing by utilizing diffuse reflection or transmission of light to obtain a plurality of detection values;

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

[0130] The clothing processing device calculates a parameter value representing the clothing material based on a plurality of detection values ​​and uses the above-mentioned clothing material identification method to identify the clothing material.

[0131] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0132] In a specific implementation of the embodiment of the present application, material identification includes the following processing:

[0133] The ultraviolet sensor is installed inside the lifting rib in a flat manner. The function of the ultraviolet sensor is to detect the material of the clothes in the drum by using the working principle of diffuse reflection after being laid flat. A photosensitive sensor is installed on the door body to detect the intensity of the visible light from the outside world that penetrates into the drum. In order to avoid the interference of ultraviolet light in the barrel, the preferred photosensitive sensor uses a visible light photosensitive sensor; the observation window is also equipped with an electric atomization function to adjust the blur level of the observation window in stages. The electric atomization glass can be installed at any position between the observation window and the photosensitive sensor. It is preferably installed at the observation window, which can more conveniently perform electric atomization and detect the intensity of light entering from the outside.

[0134] Parameter Description:

[0135] The wavelength of the ultraviolet spectrum used in this application is 10-400nm, and the absorbed wavelength is calculated according to quantum theory as △E=hv=hc / λ. The wavelength of the visible light spectrum is 400-760nm, so when detecting the intensity of external visible light projected into the treatment tube, it will not be interfered by the ultraviolet light in the treatment tube.

[0136] Control method:

[0137] After putting clothes into the treatment drum, the main control board detects the current and power of the driving motor to determine the weight of the clothes in the treatment drum. After determining that there are clothes in the treatment drum, the ultraviolet sensor on the lifting rib begins to detect the material of the clothes in the treatment drum. Through diffuse reflection, the corresponding parameter value of the clothes in the treatment drum is detected as a (the average value after multiple collections). After conversion, it is first compared with the preset value of the main board (i.e., the clothing material range) to determine whether a is within the clothing material range. If it is within the range, the ultraviolet sensor on the lifting rib detects the clothing material normally. If the material detected parameter a is not within the range of the clothing material range, the visible light sensor detects the light intensity β at this time to obtain the current light intensity β. Since visible light has a certain influence on ultraviolet light, resulting in a reduction in the number of detection values ​​obtained, the ultraviolet sensor is used to detect the material of the clothes, and the detection value obtained this time is used to calculate the parameter value a (the average value after multiple collections), and 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 clothes in the drum; if there is a deviation and the deviation is within ±10, the main board sends a signal to the observation window, and the glass of the observation window is electro-atomized. The electro-atomization treatment is divided into 5 levels, from 1 to 5 from low to high, 1 is a lower blur and a lower degree of shading, 5 is the highest blur and the highest degree of shading, which can basically completely isolate the external light source. Since the material detection parameter is within the deviation range of ±10, the observation window is atomized according to the first level of electro-atomization. If the deviation is within the range of ±20, the observation window is atomized according to the second level of electro-atomization. The highest level of atomization is the fifth level, which is complete atomization, and can basically completely isolate external light sources.

[0138] After each atomization, use a visible light sensor to detect the light intensity β after the visible light penetrates into the treatment barrel through the observation window after atomization. Each gear of electro-atomization corresponds to the light intensity β1-β5 after shading. β1-β2 The degree of atomization is light, which is suitable for the deviation range of the material identification parameter a and the closest clothing material interval within the range of ±20. β3-β4 The degree of atomization is moderate, and the inside of the barrel is basically in a dark state. At this time, the visible light has a low impact on the ultraviolet sensor. β5 is full atomization, and the observation window is completely atomized. It is suitable for detecting when the material identification parameter a is close to the interval of ±35 of polyester fiber. The detection range of this material is large and is greatly affected by visible light.

[0139] After adjusting to the corresponding atomization degree suitable for the UV sensor to detect the material at this time, the visible light detects the β light intensity to determine whether the shading effect after atomization is appropriate. The UV sensor begins to detect the clothes in the drum, collects them multiple times, and calculates the average value, which is compared with the preset value to distinguish what material it is.

[0140] For example, if the detection interval a is close to the △a interval of polyester fiber and close to the deviation of ±35 of the interval, the main board does not need to detect the light intensity at this time, because it is close to the polyester fiber material. At this time, it is determined that the electro-atomization step must be performed. The observation window is directly adjusted to the 5th gear. The visible light sensor detects and confirms that the intensity of the visible light in the drum is β5. The drum is in a state close to complete darkness. The main board controls the ultraviolet light work again to detect the material of the clothes in the drum. The detection value at this time should fall within the preset interval of polyester fiber material. The ultraviolet sensor detection is accurate after the observation window is atomized and shielded. After determining the material, adjust the water intake, rinse times, and dehydration speed to adapt the washing parameters of polyester fiber to achieve the best washing effect.
