[0056] In the related technology of washing machines, the clothes to be washed in the clothes processing drum are generally washed using several inherent washing modes, and it is impossible to detect and protect clothes of different materials in a targeted manner, which leads to different degrees of damage to the clothes during the washing process.

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

[0058] Embodiment 1:

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

[0060] Get the parameter value a that represents 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 element based on the optical signal detection method;

[0061] If the parameter value a n If it is within the target range, then according to the parameter value a n and determining the clothing material based on the correspondence between the target interval and the clothing material;

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

[0063] After the temperature adjustment process is performed, the parameter value a representing the material of the clothing is obtained again. 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-judge the a n 'Whether it is within the preset target range;

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

[0066] In this embodiment, for the parameter value a n The acquisition is obtained by the detection element based on the optical signal detection method, for example, an optical signal is emitted from an emitter in one detection element to a receiver in another detection element, and the optical signal emitted by the emitter will pass through the clothes in the clothing treatment drum, wherein a part of the optical signal is blocked and absorbed by the clothes, and another part of the optical signal penetrates the clothes and is received by the receiver in another detection element, or an optical signal is emitted from an emitter in one detection element to the clothes, and the optical signal reflected by the clothes is received by the receiver in the detection element. The optical signal has different penetration and diffuse reflection capabilities for clothes of different materials. By utilizing the difference in the penetration capabilities of the optical signal for clothes of different materials, the material of the clothes in the clothing treatment drum can be determined;

[0067] If the parameter value a n If the temperature is not within the target range, then the temperature in the current laundry treatment drum is not suitable for the detection element to detect, or the temperature of the detection element itself is not suitable, which also causes the parameter value a detected by the detection element to be n If there is an abnormality, the temperature in the laundry treatment drum of the laundry treatment device is adjusted to the target temperature range, and / or the temperature in the laundry treatment drum of the laundry treatment device is adjusted to the target temperature range, so that the temperature in the laundry treatment drum is suitable for detection by the detection device, or the temperature of the detection device itself is suitable for detection, thereby ensuring the accuracy of the detection data. Then re-obtain the parameter value a that represents the material of the clothing 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 correspondence between the target range and the material of the clothes is used to determine the material of the clothes, providing accurate and comprehensive data for selecting different washing modes for clothes of different materials, so that clothes of different materials can be tested and protected in a targeted manner.

[0068] In this embodiment, for the parameter value a n There is another way to deal with the situation that is not within the target range: the working temperature of the detection element is less than 50°C, the temperature in the clothing treatment drum is too high, and the chips and components generate heat during their own operation, which will iteratively increase the temperature of the PCB board of the detection element. The optimal temperature range for the detection element is 20°C-30°C, which is the target temperature range mentioned above. Under the condition of 30°C-50°C, the detection element can also be used normally, but there is a certain deviation from the detection parameter value within the optimal temperature range. The deviation is eliminated by the parameter value compensation strategy, so that detection can be carried out without adjusting the temperature in the clothing treatment drum, and the same accurate detection effect can be achieved.

[0069] It should be noted that, in an embodiment of the present application, diffuse reflection may be generated after the light signal contacts the clothing, and then the diffuse reflection parameter value may be obtained.

[0070] 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.

[0071] In an embodiment, the preset calculation formula for calculating the diffuse reflection parameter value may 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 (light intensity related).

[0072] In the embodiment, in order to determine the material of the clothing, a diffuse reflection standard value interval is preset, and different diffuse reflection standard value intervals correspond to different clothing materials, that is, there is a corresponding relationship between the diffuse reflection standard value interval and the clothing material.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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%.

[0078] In one embodiment, in order to determine the material of clothing, a transmission standard value interval is preset, and different transmission standard value intervals correspond to different clothing materials, that is, there is a corresponding relationship between the transmission standard value intervals and the clothing materials.

[0079] 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.

[0080] 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.

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

[0082] Optical signal detection methods include:

[0083] Controlling the emitter to emit a first light signal to the clothes in the clothes processing device, controlling the receiver to receive a second light signal passing through the clothes in the clothes processing device, or controlling the receiver to receive a third light signal reflected by the clothes in the clothes processing device;

[0084] Obtaining a parameter value a according to the second optical signal or the third optical signal;

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

[0086] The parameter value a obtained by the optical signal is as follows: Figure 5 As shown, it can be obtained by transmitting the light signal through the clothes, where the dotted line represents the clothes and the light signal transmitted through the clothes; Figure 4 As shown, it can also be obtained by reflecting the light signal on the clothes, where the dotted line represents the clothes and the light signal reflected back by the clothes. Clothes of different materials have different transmission and reflection capabilities for light signals, so the parameter value a can be obtained in the above two ways.

[0087] Specifically, for parameter value a n The acquisition method is: through the detection element to transmit and receive the light signal, each time a parameter value a1 can be obtained, repeat the acquisition m times, and obtain a total of parameter values ​​a1 to parameter values ​​a m , through the processor to calculate the parameter value a1 ~ parameter value a m The average value of the parameter a is obtained n , that is, the parameter value a n =(parameter value a1+parameter value a2+......parameter value a m) / m, m can be 20, and a parameter value a is collected every 0.5s. If the parameter value a n If it is within the target range, then according to the parameter value a n The corresponding relationship between the target range and the clothing material determines the clothing material. The parameter value a can be obtained by taking the average value. n The material parameter values ​​represented are more accurate, and the larger or smaller parameter values ​​obtained are shielded, making the detection results more accurate.

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

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

[0090] Determine the parameter value a n Is it in an invalid value range? If it is in an invalid value range, the clothes processing drum is controlled to rotate at a target speed for a target time and then stop rotating, and the parameter value a is obtained again. n .

[0091] In this embodiment, the invalid interval includes a preset upper limit range or a preset lower limit range. For example, taking the light signal detection method using diffuse reflection as an example, the preset upper limit range is 0.1-20, and the preset lower limit range is 391-399. nIf the detection position of the clothes is within the preset upper limit range or the preset lower limit range, the clothes processing drum is controlled to rotate at the target speed for the target time and then stop rotating. During the rotation of the clothes processing drum, the position of the clothes is also adjusted accordingly, thereby eliminating the inaccurate detection position of the clothes and ensuring that the detection element remains effective for clothes detection.

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

[0093] Adjusting the temperature in a laundry treatment drum of a laundry treatment device to adjust the temperature in the laundry treatment drum to a target temperature range includes:

[0094] The temperature value t1 in the laundry treatment drum is obtained, and 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 in the laundry treatment drum to the target temperature range. If t1 is less than the target temperature range, the heating mode is activated to increase the temperature in the laundry treatment drum to the target temperature range. The target temperature value range can be 20°C-30°C.

[0095] In the parameter value a n If the temperature is not within the target range, then the temperature in the current laundry treatment drum is not suitable for detection by the detection element, resulting in the parameter value a detected by the detection element. n There is an abnormality. At this time, the temperature in the laundry treatment drum of the laundry treatment device is adjusted to the target temperature range. The specific adjustment method is: obtain the temperature value t1 in the laundry treatment drum, compare the temperature value t1 with the target temperature range, if t1 is greater than the target temperature range, start the cooling mode to reduce the temperature in the laundry treatment drum to the target temperature range, if t1 is less than the target temperature range, start the heating mode to increase the temperature in the laundry treatment drum to the target temperature range. When the temperature in the laundry treatment drum is within the target range, the working environment of the detection element can be made suitable for the detection work of the detection element, and the detection is more accurate in identifying the material of the clothing.

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

[0097] Adjusting the temperature in a laundry treatment drum of a laundry treatment device to adjust the temperature of a detection element to a target temperature range includes:

[0098] Obtaining a resistance value r1 of a thermistor of the detection element, where the resistance value r1 is used to represent 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, the cooling mode is started to adjust the temperature of the detection element to the target temperature range. If r1 is greater than the target resistance value range, the heating mode is started to adjust the temperature of the detection element to the target temperature range. The target resistance value range can be (target resistance value -5 to target resistance value +5).

[0100] In the parameter value a n If it is not within the target range, the current temperature of the test piece itself is not suitable for the test piece to detect, resulting in the parameter value a detected by the test piece n There is an abnormality. At this time, the temperature of the detection element is adjusted to the target temperature range by adjusting the temperature in the clothing treatment drum of the clothing treatment equipment. The specific adjustment method is: obtain the resistance value r1 of the thermistor of the detection element, and the resistance value r1 is used to characterize the temperature of the detection element; compare the resistance value r1 with the target resistance value interval. If r1 is less than the target resistance value interval, it proves that the temperature in the current clothing treatment drum is too high, resulting in a small resistance value r1. It is necessary to start the cooling mode to reduce the temperature in the clothing treatment drum so that the temperature of the detection element is adjusted to the target temperature range. If r1 is greater than the target resistance value interval, it proves that the temperature in the current clothing treatment drum is too low, resulting in a large resistance value r1. It is necessary to start the heating mode to increase the temperature in the clothing treatment drum so that the temperature of the detection element is adjusted to the target temperature range. When the temperature in the clothing treatment drum is within the target range, the temperature of the detection element itself can be made appropriate, the working environment of the detection element is suitable for the detection work of the detection element, and the detection is more accurate in identifying the material of the clothing.

[0101] Preferably, in order to further ensure the detection accuracy of the detection element, the temperature value t1 in the clothing treatment drum can be obtained first, and the temperature value t1 can be compared with the target temperature range. If t1 is greater than the target temperature range, the cooling mode is started to reduce the temperature in the clothing treatment drum to the target temperature range, and then the resistance value r1 of the thermistor of the detection element is obtained, and 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 in the clothing treatment drum and the temperature of the detection element itself are normal at this time and can be detected normally. If the resistance value r1 is not within the target resistance value range, the cooling mode is continued to be started until the resistance value r1 is within the target resistance value range, and the cooling mode is stopped and normal detection is performed.

[0102] Similarly, if t1 is less than the target temperature range, the heating mode is started to reduce the temperature in the clothing treatment drum to the target temperature range, and then the resistance value r1 of the thermistor of the detection element is obtained, and 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 in the clothing treatment drum and the temperature of the detection element itself are normal at this time, and normal detection can be performed. If the resistance value r1 is not within the target resistance value range, the heating mode is continued to be started until the resistance value r1 is within the target resistance value range, and the heating mode is stopped for normal detection.

[0103] Optionally, in an implementation of this embodiment,

[0104] The clothes processing device includes a duct fan and a duct electric heating element;

[0105] The cooling mode includes: controlling the air duct fan of the clothes processing equipment to blow air into the clothes processing drum and the air duct electric heating element is in a non-working state;

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

[0107] In this embodiment, the cooling mode is achieved by: controlling the duct fan of the clothes processing device to blow air into the clothes processing drum and the duct electric heating element is in a non-working state, at which time the air blown by the duct fan is used to dissipate heat in the clothes processing drum, thereby reducing the temperature in the clothes processing drum;

[0108] The heating mode is achieved by: controlling the duct fan of the clothes processing equipment to blow air into the clothes processing drum and the duct electric heating element is in working state. At this time, the duct fan blows hot air, thereby increasing the temperature in the clothes processing drum. The duct fan and the duct electric heating element are built-in parts of the washing machine with drying function and are easy to use.

[0109] Optionally, in an implementation of this embodiment,

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

[0111] Obtain the temperature value t1 in the laundry processing drum, compare the temperature value t1 with the target temperature range, and if t1 is greater than the target temperature range, n '=a n +a n ×k Update 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 t1 temperature, the higher the k value. The higher the t1 temperature, the greater the deviation from the parameter value detected within the optimal temperature range to a certain extent. Therefore, by increasing the k value, the compensation strategy is more accurate.

[0112] Update the parameter value a by using the parameter value compensation strategy n , thereby eliminating the deviation from the detection parameter value within the optimal temperature range. The deviation is eliminated through the parameter value compensation strategy, so that the detection can be carried out without adjusting the temperature in the clothing treatment drum, and the same accurate detection effect can be achieved.

[0113] Embodiment 2

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

[0115] n detection elements, the detection element comprising an emitter 2 and a receiver 3, respectively used for transmitting and receiving optical signals, wherein n≥1;

[0116] A processor is configured to control n detection elements to transmit and receive light signals, and determine a parameter value a representing the material of the clothing according to the received light signals. n , or is also used to update the parameter value a according to the parameter value compensation strategy n ;

[0117] The temperature sensing module 4 is electrically connected to the processor and is used to obtain the temperature value in the clothes processing drum 6 in the clothes processing device;

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

[0119] In this embodiment, the processor controls the emitter 2 in one detection element to transmit a light signal to the receiver 3 in another detection element. The light signal emitted by the emitter 2 passes through the clothes in the clothing treatment drum 6, wherein a part of the light signal is blocked and absorbed by the clothes, and another part of the light signal penetrates the clothes and is received by the receiver 3 in another detection element. Alternatively, the emitter in one detection element transmits a light signal to the clothes, and the light signal reflected by the clothes is received by the receiver in the detection element. The light signal has different penetration and reflection capabilities for clothes of different materials. By utilizing the difference in the penetration capabilities of the light signal for clothes of different materials, the material of the clothes in the clothing treatment drum 6 can be determined.

[0120] The temperature sensing module 4 is electrically connected to the processor and is used to obtain the temperature value in the clothes processing drum 6 in the clothes processing device. When the temperature in the clothes processing drum 6 is not suitable for the detection element to work, it will cause the parameter value a detected by the detection element to be n There is an abnormality. At this time, the temperature in the laundry processing tub 6 is adjusted by the temperature adjustment module to adjust the temperature in the laundry processing tub 6 to the target temperature range, so that the temperature in the laundry processing tub 6 is suitable for detection by the detection element, thereby ensuring the accuracy of the detection data. n The correspondence between the target range and the material of the clothes is used to determine the material of the clothes, providing accurate and comprehensive data for selecting different washing modes for clothes of different materials, so that clothes of different materials can be tested and protected in a targeted manner.

[0121] Optionally, in an implementation of this embodiment,

[0122] Material testing equipment also includes:

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

[0124] When the temperature of the test piece itself is not appropriate, it will also cause the parameter value a detected by the test piece to be n If there is an abnormality, the temperature in the laundry treatment drum 6 is adjusted to adjust the temperature of the detection element to the target temperature range. The resistance value r1 of the thermistor of 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, the cooling mode is started to adjust the temperature of the detection element to the target temperature range. If r1 is greater than the target resistance value range, the heating mode is started to adjust the temperature of the detection element to the target temperature range, thereby ensuring the accuracy of the detection data. According to the detected parameter value a nThe correspondence between the target range and the material of the clothes is used to determine the material of the clothes, providing accurate and comprehensive data for selecting different washing modes for clothes of different materials, so that clothes of different materials can be tested and protected in a targeted manner.

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

[0126] The inner wall of the clothes processing drum 6 is provided with n lifting ribs 1 at equal intervals, the n detecting elements correspond to the n lifting ribs 1 one by one, and the detecting elements are arranged on the corresponding lifting ribs 1 .

[0127] The lifting ribs 1 are arranged at equal intervals, that is, n detection components are arranged at equal intervals on the inner wall of the clothing processing drum 6, forming a relatively uniform annular optical signal network or a cross signal network, which can more effectively and comprehensively cover the clothes in the clothing processing drum 6, and can more comprehensively obtain information related to the clothing material, so that the clothing processing drum can detect the clothing material more fully and accurately.

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

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

[0130] In this embodiment, the emitter of the ultraviolet sensor emits ultraviolet rays in the wavelength range of 100-400nm, and transmits ultraviolet rays of 100-400nm to the receiving electrode 3 in another detecting element through the emitter 2 in one of the detecting elements. The ultraviolet rays of 100-400nm emitted by the emitter 2 will pass through the clothes in the clothing treatment drum 4, wherein a part of the light signal is blocked and absorbed by the clothes, and another part of the ultraviolet rays of 100-400nm penetrates the clothes and is received by the receiving electrode 3 in another detecting element, or the light signal is emitted to the clothes through the emitter 2 in one detecting element, and the light signal reflected by the clothes is received by the receiving electrode 3 in the detecting element. The ultraviolet rays of 100-400nm are sensitive to clothes of different materials. Clothes have different penetration and reflection abilities. The difference in penetration and reflection abilities of 100-400nm ultraviolet rays on clothes of different materials is used. The receiving electrode 3 converts the received ultraviolet rays into electrical signals. After the electrical signals are processed by the MCU chip in the processor, they are converted into digital signals. The processor then generates comparable ultraviolet data and compares them with the preset value ranges of various materials. For example, cotton, wool, silk, polyester, linen and other materials all have non-overlapping preset value ranges. By judging the preset value range where the digital signal is located, the corresponding clothing material can be obtained. According to the judged material, a washing mode matching the material can be selected, thereby achieving targeted protection for clothes of different materials during the washing process.

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

[0132] The lifting rib 1 has a groove portion 7 which is recessed from the top surface to the inside of the lifting rib 1 . The bottom surface of the groove portion 7 is a first wall surface 5 facing the clothes in the clothing processing drum 6 . The first wall surface 5 is a straight wall surface. The emitter 2 and the receiver 3 in the detection element are both arranged on the first wall surface 5 and accommodated in the groove portion 7 .

[0133] In this embodiment, the emitter 2 and the receiving electrode 3 of the detection element are arranged in a flat manner on the lifting rib 1. The light signal is emitted to the clothes through the emitter 2 in the detection element, and the light signal reflected by the clothes is received by the receiving electrode 3 in the detection element. The receiving electrode 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, compares it with the preset value range of various materials, and determines the preset value range where the digital signal is located to obtain the corresponding clothing material.

[0134] By designing a groove portion 7 on the top surface of the lifting rib 1, with lateral openings on both sides of the groove portion 7, the detection component can use the groove portion 7 as a carrier to more fully exert the detection effect, the transmitting end of the transmitter 2 can emit a light signal from the bottom of the groove portion 7 toward the outside of the groove, and the receiving end of the receiver 3 can receive the light signal passing through the groove portion 7. In this process, the lateral opening of the groove portion 7 provides an effective passage space for the emission and reception of the light signal, avoiding the light signal from being blocked, so that the detection component is in a better working state and has a more accurate detection result. Furthermore, a transparent cover can be set at the notch of the groove portion 7, and the setting of the transparent cover protects the detection component. The transparent baffle can not only play a waterproof role for the detection element, but also play a high temperature resistant role. When the water temperature in the clothing processing drum 6 is high, the transparent baffle has a certain temperature insulation effect on the detection element, thereby providing a good working environment for the detection element; the transparent baffle made of transparent material will not affect the emission and reception of optical signals. Preferably, the transparent baffle can be made of acrylic or glass material. In addition to having high transparency, acrylic or glass material has good heat insulation function, and the surface of acrylic or glass material is relatively smooth, without wrinkles and not easy to produce wrinkles, so that the emission and reception of optical signals by the detection element will not be affected, and the detection result will be more accurate.
