They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] In washing machine technology, the clothes to be washed in the drum are generally washed using a few fixed washing modes. This makes it impossible to specifically detect and protect clothes of different materials, which can easily cause varying degrees of damage to the clothes during the washing process.

[0057] Based on this, the following embodiments are proposed.

[0058] Example 1:

[0059] like Figure 5 As shown, this embodiment provides a material detection method for identifying the material of clothing in a clothing processing device. The material detection method includes:

[0060] Obtain the parameter value a that characterizes the material of the clothing. n And determine the parameter value a n Whether it is within the preset target range, parameter value a n It is obtained by the detection method based on optical signals of the detected component;

[0061] If parameter value a n If it is within the target range, then according to the parameter value a n The material of clothing is determined by the correspondence between the target range and the clothing material.

[0062] If the parameter value a n If it is not within the target interval, then:

[0063] After temperature adjustment, the parameter value 'a' representing the clothing material is reacquired. n And determine the parameter value a nIs it within the preset target range, or...

[0064] Update the parameter value a according to the parameter value compensation strategy. n For a n ', and re-evaluate the aforementioned a n Is it within the preset target range?

[0065] The temperature adjustment process includes: adjusting the temperature inside the garment processing drum of the garment processing device to adjust the temperature inside the garment processing drum to a target temperature range, and / or adjusting the temperature inside the garment processing drum of the garment processing device to adjust the temperature of the detection element to a target temperature range.

[0066] In this embodiment, for parameter value a n The light signal is obtained by the detection device based on the optical signal detection method. For example, the light signal is emitted from the emitter in one detection device to the receiver in another detection device. The light signal emitted by the emitter passes through the clothes in the clothes processing drum. Part of the light signal is blocked and absorbed by the clothes, while the other part of the light signal penetrates the clothes and is received by the receiver in the other detection device. Alternatively, the light signal is emitted from the emitter in one detection device to the clothes, and the light signal reflected back by the clothes is received by the receiver in the same detection device. The light signal has different penetration and diffuse reflection capabilities for different materials of clothes. By utilizing this difference in the penetration capability of the light signal for different materials of clothes, the material of the clothes in the clothes processing drum can be determined.

[0067] If parameter value a n If the temperature is not within the target range, it may be due to an unsuitable temperature inside the garment processing drum or an unsuitable temperature of the detector itself, which will also affect the parameter value 'a' detected by the detector. n If an anomaly is detected, adjust the temperature inside the garment processing drum of the garment processing equipment to bring it to the target temperature range, and / or adjust the temperature inside the garment processing drum of the garment processing equipment to bring the temperature of the test piece to the target temperature range. This ensures that the temperature inside the garment processing drum is suitable for the test piece, or that the temperature of the test piece itself is suitable for testing, thereby ensuring the accuracy of the test data. Then, re-acquire the parameter value 'a' characterizing the garment material. n And determine the parameter value a n Is it within the preset target range? n If it is within the target range, then according to the parameter value a n The correlation between target range and clothing material determines the clothing material, providing accurate and comprehensive data for selecting different washing modes for different materials, thus enabling targeted testing and protection of clothing of different materials.

[0068] In this embodiment, for parameter value a n For cases outside the target temperature range, another approach is available: If the operating temperature of the detection device is <50℃, the temperature inside the garment processing drum will be too high. Combined with the heat generated by the chip and components during operation, this will cause the temperature of the detection device's PCB board to increase iteratively. The optimal temperature range for the detection device is 20℃-30℃, which is the aforementioned target temperature range. While the detection device can also be used normally at 30℃-50℃, there will be a certain deviation from the detection parameter values ​​within the optimal temperature range. A parameter value compensation strategy can be used to eliminate this deviation, allowing for accurate detection without adjusting the temperature inside the garment processing drum.

[0069] It should be noted that, in one embodiment of this application, the light signal can generate diffuse reflection after coming into contact with clothing, thereby obtaining the diffuse reflection parameter value.

[0070] 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.

[0071] In an 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).

[0072] In this embodiment, in order to determine the material of the clothing, a standard range of diffuse reflection values ​​is preset. Different standard ranges of diffuse reflection values ​​correspond to different clothing materials. In other words, there is a correspondence between the standard range of diffuse reflection values ​​and the clothing material.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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%.

[0078] In one embodiment, in order to determine the material of the clothing, a transmission standard value range is preset. Different transmission standard value ranges correspond to different clothing materials. In other words, there is a correspondence between the transmission standard value range and the clothing material.

[0079] 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.

[0080] 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.

[0081] Optionally, in one implementation of this embodiment, such as Figure 4 , 5 As shown,

[0082] Optical signal detection methods include:

[0083] The transmitter is controlled to emit a first light signal into the clothes in the clothes processing device, and the receiver is controlled to receive a second light signal that passes through the clothes in the clothes processing device or a third light signal that is reflected by the clothes in the clothes processing device.

[0084] The parameter value a is obtained based on the second or third optical signal;

[0085] Repeatedly obtain multiple parameter values ​​'a', and calculate the parameter value 'a' based on the multiple parameter values ​​'a'. n .

[0086] The parameter value 'a' obtained from the optical signal, such as Figure 5 As shown, this can be obtained by transmitting light signals through clothing, where the dashed lines represent the clothing and the light signals transmitted through it; for example... Figure 4 As shown, it can also be obtained by reflecting light signals on clothing. The dashed line represents clothing and the light signal reflected back by the clothing. Different materials of clothing have different transmission and reflection capabilities for light signals. Therefore, the parameter value a can be obtained in the above two ways.

[0087] Specifically, for parameter value a n The acquisition method is as follows: the optical signal is transmitted and received by the detection device. Each reception yields a parameter value a1. This process is repeated m times to obtain a total of parameter values ​​a1 to a1. m The processor calculates parameter values ​​a1 to a1. m The average value of parameter a is obtained. n That is, parameter value a n = (parameter value a1 + parameter value a2 + ... + parameter value a) m) / m, where m can be 20, and a parameter value 'a' is collected every 0.5 seconds. If the parameter value 'a'... n If it is within the target range, then according to the parameter value a n The relationship between the target interval and the clothing material is used to determine the clothing material. Using the average value, the parameter value a can be optimized. n The material parameter values ​​represented are more accurate, and the larger or smaller parameter values ​​obtained are masked, making the test results more accurate.

[0088] Optionally, in one implementation of this embodiment, such as Figure 5 As shown,

[0089] In judging parameter value a n Before determining whether the target range is within a preset range, the method also includes:

[0090] Determine the parameter value a n If the value is within an invalid value range, the garment processing drum will rotate at the target speed for the target duration and then stop rotating. The parameter value 'a' will then be reacquired. n .

[0091] In this embodiment, the invalid range includes a preset upper limit range or a preset lower limit range. For example, taking the diffuse reflection light signal detection method as an example, the preset upper limit range is 0.1-20, and the preset lower limit range is 391-399. If the obtained parameter value a nIf the clothing is within the preset upper or lower limit range, the clothing processing drum will rotate at the target speed for the target duration and then stop rotating. During the rotation of the clothing processing drum, the position of the clothing will also be adjusted accordingly, thereby eliminating the situation of inaccurate clothing detection position and ensuring that the detection device remains effective in detecting clothing.

[0092] Optionally, in one implementation of this embodiment, such as Figure 6 As shown,

[0093] Adjusting the temperature inside the garment processing drum of the garment processing equipment to bring the temperature inside the drum to the target temperature range includes:

[0094] The system acquires the temperature value t1 inside the garment processing drum and compares it with the target temperature range. If t1 is greater than the target temperature range, a cooling mode is activated to lower the temperature inside the garment processing drum to the target temperature range. If t1 is less than the target temperature range, a heating mode is activated to raise the temperature inside the garment processing drum to the target temperature range. The target temperature range can be 20℃-30℃.

[0095] In parameter value a n If the temperature is not within the target range, it indicates that the current temperature inside the garment processing drum is unsuitable for the detection device, resulting in the parameter value 'a' being detected by the device. n If an anomaly is detected, the temperature inside the garment processing drum of the garment processing equipment is adjusted to reach the target temperature range. Specifically, the adjustment method is as follows: The temperature value t1 inside the garment processing drum is obtained and compared with the target temperature range. If t1 is greater than the target temperature range, a cooling mode is activated to lower the temperature inside the garment processing drum to the target temperature range. If t1 is less than the target temperature range, a heating mode is activated to raise the temperature inside the garment processing drum to the target temperature range. When the temperature inside the garment processing drum is within the target range, the working environment of the detected item is suitable for the detection work, resulting in more accurate identification of garment materials.

[0096] Optionally, in one implementation of this embodiment, such as Figure 6 As shown,

[0097] Adjusting the temperature inside the garment processing drum of the garment processing equipment to bring the temperature of the detection piece to the target temperature range includes:

[0098] Obtain the resistance value r1 of the thermistor of the detection element. The resistance value r1 is used to characterize the temperature of the detection element.

[0099] The resistance value r1 is compared with the target resistance value range. If r1 is less than the target resistance value range, a cooling mode is activated to adjust the temperature of the sensing element to the target temperature range. If r1 is greater than the target resistance value range, a heating mode is activated to adjust the temperature of the sensing element to the target temperature range. The target resistance value range can be (target resistance value - 5 to target resistance value + 5).

[0100] In parameter value a n If the temperature of the sample is not within the target range, it may be that the temperature of the sample itself is unsuitable for the sample to detect, resulting in the measured parameter value 'a' being incorrect. n An anomaly is detected. In this case, the temperature inside the garment processing drum of the garment processing equipment is adjusted to bring the temperature of the detection element to the target temperature range. The specific adjustment method is as follows: Obtain the resistance value r1 of the thermistor of the detection element. The resistance value r1 is used to characterize the temperature of the detection element. Compare the resistance value r1 with the target resistance value range. If r1 is less than the target resistance value range, it indicates that the current temperature inside the garment processing drum is too high, resulting in a low resistance value r1. In this case, a cooling mode needs to be activated to lower the temperature inside the garment processing drum, thus adjusting the temperature of the detection element to the target temperature range. If r1 is greater than the target resistance value range, it indicates that the current temperature inside the garment processing drum is too low, resulting in a high resistance value r1. In this case, a heating mode needs to be activated to raise the temperature inside the garment processing drum, thus adjusting the temperature of the detection element to the target temperature range. When the temperature inside the garment processing drum is within the target range, the temperature of the detection element itself is suitable, and the working environment of the detection element is suitable for its detection work, resulting in more accurate identification of garment materials.

[0101] Preferably, to further ensure the accuracy of the detection, the temperature value t1 inside the garment processing drum can be obtained first. The temperature value t1 is compared with the target temperature range. If t1 is greater than the target temperature range, the cooling mode is activated to reduce the temperature inside the garment processing drum to the target temperature range. Then, the resistance value r1 of the thermistor of the detection device is obtained. The resistance value r1 is used to characterize the temperature of the detection device. The resistance value r1 is compared with the target resistance value range. If the resistance value r1 is within the target resistance value range, it proves that the temperature inside the garment processing drum and the temperature of the detection device itself are normal and can be detected normally. If the resistance value r1 is not within the target resistance value range, the cooling mode is activated again until the resistance value r1 is within the target resistance value range, then the cooling mode is stopped and the detection is normal.

[0102] Similarly, if t1 is less than the target temperature range, the heating mode is activated to lower the temperature inside the garment processing drum to the target temperature range. Then, the resistance value r1 of the thermistor of the detection element is obtained. The resistance value r1 is used to characterize the temperature of the detection element. The resistance value r1 is compared with the target resistance value range. If the resistance value r1 is within the target resistance value range, it proves that the temperature inside the garment processing drum and the temperature of the detection element itself are normal and can be detected normally. If the resistance value r1 is not within the target resistance value range, the heating mode is activated again until the resistance value r1 is within the target resistance value range, then the heating mode is stopped and normal detection is performed.

[0103] Alternatively, in one implementation of this embodiment,

[0104] Clothing processing equipment includes air duct fans and air duct electric heating elements;

[0105] Cooling modes include: controlling the air duct fan of the clothing processing equipment to blow air into the clothing processing drum while the air duct electric heating element is in a non-operating state;

[0106] The heating mode includes: controlling the air duct fan of the garment processing equipment to blow air into the garment processing drum and the air duct electric heating element is in working condition.

[0107] In this embodiment, the cooling mode is achieved by controlling the air duct fan of the clothing processing equipment to blow air into the clothing processing drum while the air duct electric heating element is not working. At this time, the air blown by the air duct fan is used to dissipate heat inside the clothing processing drum, thereby reducing the temperature inside the clothing processing drum.

[0108] The heating mode works by controlling the air duct fan of the clothes handling equipment to blow air into the clothes handling drum, while the air duct electric heating element is in operation. At this time, the air duct fan blows hot air, thus raising the temperature inside the clothes handling drum. The air duct fan and air duct electric heating element are built-in components of washing machines with drying functions, making them convenient to use.

[0109] Alternatively, in one implementation of this embodiment,

[0110] The parameter value a is updated according to the parameter value compensation strategy. n For a n ',include:

[0111] Obtain the temperature value t1 inside the garment processing drum, compare the temperature value t1 with the target temperature range, and if t1 is greater than the target temperature range, then according to a... n '=a n +a n ×k updates the parameter value a n It is understandable that a n '=a n +a n ×k is an '=a n +a n Multiply by k, where 2% ≤ k ≤ 4%, or k = 3%, and the higher the temperature t1, the higher the value of k. The higher the temperature t1, the greater the deviation from the parameter value detected within the optimal temperature range. Therefore, by increasing the value of k, the compensation strategy becomes more accurate.

[0112] The parameter value a is updated using a parameter value compensation strategy. n This eliminates deviations from the detection parameter values ​​within the optimal temperature range. By using a parameter value compensation strategy to eliminate deviations, detection can be performed without adjusting the temperature inside the garment processing drum, achieving the same accurate detection results.

[0113] Example 2

[0114] like Figure 1-3 As shown in this embodiment, a material detection device is provided for identifying the material of clothing in a clothing processing device, including:

[0115] There are n detection devices, each including an emitter 2 and a receiver 3, used for transmitting and receiving optical signals respectively, where n≥1;

[0116] The processor is configured to control n detectors to transmit and receive light signals, and to determine the parameter value 'a' characterizing the material of the clothing based on the received light signals. n Alternatively, it can be used to update the parameter value a according to a parameter value compensation strategy. n ;

[0117] Temperature sensing module 4, which is electrically connected to the processor, is used to obtain the temperature value inside the clothing processing drum 6 in the clothing processing equipment;

[0118] The temperature control module is used to adjust the temperature value inside the garment processing drum 6 under the control of the processor to adjust the temperature inside the garment processing drum to the target temperature range, and / or to adjust the temperature inside the garment processing drum of the garment processing device to adjust the temperature of the detection element to the target temperature range.

[0119] In this embodiment, the processor controls the emitter 2 in one detector to emit a light signal to the receiver 3 in another detector. The light signal emitted by the emitter 2 passes through the clothes in the clothes processing drum 6. Part of the light signal is blocked and absorbed by the clothes, while the other part of the light signal penetrates the clothes and is received by the receiver 3 in the other detector. Alternatively, the emitter in one detector emits a light signal to the clothes, and the light signal reflected back by the clothes is received by the receiver in that detector. The light signal has different penetration and reflection capabilities for different types of clothes. By utilizing this difference in the penetration capability of the light signal for different types of clothes, the material of the clothes in the clothes processing drum 6 can be determined.

[0120] Temperature sensing module 4, electrically connected to the processor, is used to acquire the temperature value inside the garment processing drum 6 of the garment processing equipment. When the temperature inside the garment processing drum 6 is unsuitable for the detection element to operate, it will cause the parameter value 'a' detected by the detection element to be affected. n An anomaly is detected. In this case, the temperature inside the garment processing drum 6 is adjusted via the temperature control module to bring it within the target temperature range. This ensures the temperature inside the garment processing drum 6 is suitable for the testing of the sample, thereby guaranteeing the accuracy of the test data. Based on the detected parameter value a... n The correlation between target range and clothing material determines the clothing material, providing accurate and comprehensive data for selecting different washing modes for different materials, thus enabling targeted testing and protection of clothing of different materials.

[0121] Alternatively, in one implementation of this embodiment,

[0122] Material testing equipment also includes:

[0123] The resistance detection module, electrically connected to the processor, is used to obtain the resistance value of the thermistor of the detection device.

[0124] When the temperature of the test piece itself is unsuitable, it will also cause the measured parameter value a to change. n An anomaly is detected. In this case, the temperature inside the garment processing drum 6 is adjusted to bring the temperature of the detection element to the target temperature range. The resistance value r1 of the thermistor in the detection element is obtained through the resistance detection module. The resistance value r1 is used to characterize the temperature of the detection element. The resistance value r1 is compared with the target resistance value range. If r1 is less than the target resistance value range, a cooling mode is activated to adjust the temperature of the detection element to the target temperature range. If r1 is greater than the target resistance value range, a heating mode is activated to adjust the temperature of the detection element to the target temperature range, thereby ensuring the accuracy of the detection data. Based on the detected parameter value a... nThe correlation between target range and clothing material determines the clothing material, providing accurate and comprehensive data for selecting different washing modes for different materials, thus enabling targeted testing and protection of clothing of different materials.

[0125] Optionally, in one implementation of this embodiment, such as Figure 4 As shown,

[0126] The inner wall of the garment processing cylinder 6 is provided with n lifting ribs 1 at equal intervals. The n detection elements correspond one-to-one with the n lifting ribs 1, and the detection elements are set on the corresponding lifting ribs 1.

[0127] The lifting ribs 1 are set at equal intervals, that is, n detection elements are set at equal intervals on the inner wall of the clothing processing drum 6, forming a relatively uniform ring light signal network or cross signal network, which can more effectively and comprehensively cover the clothes in the clothing processing drum 6, and can more comprehensively obtain relevant information about the clothing material, making the clothing processing drum more thorough and accurate in detecting the clothing material.

[0128] Optionally, in one implementation of this embodiment, such as Figure 4 As shown,

[0129] The detection component is an ultraviolet sensor, with emitter 2 being the emitter of the ultraviolet sensor, receiver 3 being the receiver of the ultraviolet sensor, and the light signal being an ultraviolet light signal.

[0130] In this embodiment, the ultraviolet sensor emits ultraviolet light with a wavelength range of 100-400nm. This 100-400nm ultraviolet light is emitted from the emitter 2 of one detector element to the receiver 3 of another detector element. The 100-400nm ultraviolet light emitted by the emitter 2 passes through the clothing in the clothing processing drum 4. Part of the light signal is blocked or absorbed by the clothing, while the remaining 100-400nm ultraviolet light penetrates the clothing and is received by the receiver 3 of the other detector element. Alternatively, the light signal can be emitted from the emitter 2 of one detector element to the clothing, and the light signal reflected back by the clothing is received by the receiver 3 of that detector element. The 100-400nm ultraviolet light is sensitive to different materials. Clothing has different penetration and reflection capabilities. Utilizing the differences in penetration and reflection capabilities of 100-400nm ultraviolet light on different clothing materials, receiver 3 converts the received ultraviolet light into an electrical signal. After the electrical signal is processed by the MCU chip in the processor, it is converted into a digital signal. The processor then generates comparable ultraviolet data and compares it with preset value ranges for various materials, such as cotton, wool, silk, polyester fiber, and linen, which all have non-overlapping preset value ranges. By determining the preset value range in which the digital signal falls, the corresponding clothing material can be obtained. Based on the determined material, a washing mode matching that material can be selected, thereby achieving targeted protection for different types of clothing during the washing process.

[0131] Optionally, in one implementation of this embodiment, such as Figure 1 As shown,

[0132] The lifting rib 1 has a groove 7 that is recessed from the top to the inside of the lifting rib 1. The bottom surface of the groove 7 is a first wall surface 5 facing the clothes in the clothes processing tube 6. The first wall surface 5 is a flat wall surface. The emitting electrode 2 and the receiving electrode 3 in the detection element are both disposed on the first wall surface 5 and housed in the groove 7.

[0133] In this embodiment, the emitter 2 and receiver 3 of the detection element are arranged flat on the lifting rib 1. The emitter 2 of one detection element emits a light signal to the clothing. The light signal reflected back by the clothing is received by the receiver 3 of the detection element. The receiver 3 converts the received ultraviolet light into an electrical signal. The electrical signal is processed by the MCU chip in the processor and converted into a digital signal. The processor then generates comparable ultraviolet data and compares it with the preset value range of various materials. By determining the preset value range in which the digital signal is located, the corresponding clothing material can be obtained.

[0134] By designing a groove 7 on the top surface of the lifting rib 1, with lateral openings on both sides of the groove 7, the detection component can more fully exert its detection effect using the groove 7 as a carrier. The emitting end of the emitting electrode 2 can emit light signals from the bottom of the groove 7 towards the outside of the groove, and the receiving end of the receiving electrode 3 can receive the light signals passing through the groove 7. During this process, the lateral openings of the groove 7 provide effective passage space for the emission and reception of light signals, avoiding obstruction of the light signals, thereby ensuring that the detection component is in a better working state and has more accurate detection results. Furthermore, a transparent cover can be provided at the opening of the groove 7 to protect the detection component. The transparent cover serves both to waterproof the test piece and to provide high-temperature resistance. When the water temperature inside the garment processing drum 6 is high, the transparent cover provides a certain degree of heat insulation for the test piece, thus providing a good working environment. The transparent cover, made of transparent material, does not affect the transmission and reception of light signals. Preferably, the transparent cover can be made of acrylic or glass. Besides high transparency, acrylic or glass has good heat insulation properties, and its surface is relatively smooth, wrinkle-free, and resistant to wrinkling. This ensures that the transmission and reception of light signals by the test piece are not affected, resulting in more accurate test results.

In this case, the temperature inside the garment processing drum of the garment processing equipment is adjusted to the target temperature range, and / or the temperature inside the garment processing drum of the garment processing equipment is adjusted to the target temperature range. This ensures that the temperature inside the garment processing drum is suitable for the detection element, or that the temperature of the detection element itself is suitable for detection, thereby ensuring the accuracy of the detection data. Then, the parameter value 'a' characterizing the garment material is reacquired. n And determine the parameter value a n Is it within the preset target range? n If it is within the target range, then according to the parameter value a n The correlation between target range and clothing material determines the clothing material, providing accurate and comprehensive data for selecting different washing modes for different materials, thus enabling targeted testing and protection of clothing of different materials.

In this case, the temperature inside the garment processing drum of the garment processing equipment is adjusted to the target temperature range, and / or the temperature inside the garment processing drum of the garment processing equipment is adjusted to the target temperature range.

[0142] In summary, the ingenious design of the material testing method lies in:

[0143] First, parameter values ​​are obtained using optical signal detection. Different materials exhibit varying degrees of penetration and reflection from optical signals, allowing for the identification of the material within the garment processing drum. This material detection method adjusts the temperature within the processing drum to a target range, thereby aligning the temperature of the detection element with the target temperature range. This ensures the accuracy of the detection data by optimizing either the drum temperature or the element's own temperature for detection. Based on the correlation between parameter values, target ranges, and garment materials, accurate and comprehensive data is provided for selecting different washing modes for different materials, enabling targeted detection and protection of garments made from various materials.

[0144] Second, by obtaining the resistance value of the thermistor of the detection component, the temperature of the detection component is characterized by the resistance value. The resistance value is compared with the target resistance value range to determine whether the temperature of the detection component itself is appropriate. Further, it is determined whether the temperature inside the clothing processing drum needs to be adjusted, so that the detection component has a suitable working temperature and the detection can identify the clothing material more accurately.
