For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0052] In the related technology of clothing material detection, the intelligent camera recognizes the clothing material through camera sampling technology, which is a technology integrating image recognition technology, deep learning algorithm and expert system. The camera sampling technology discriminates the clothing material through deep learning algorithm and expert system, but the precision of the camera sampling technology for clothing material detection is low.

[0053] Based on this, the following embodiments are proposed.

[0054] Embodiment one:

[0055] As shown in Figure 2 The present embodiment provides a clothing treatment drum, comprising:

[0056] a drum body 1;

[0057] a detection piece, the detection piece comprising an emitter 2 and a receiver 3, both the emitter 2 and the receiver 3 being connected to the inner wall of the drum body 1 through a connecting assembly 4;

[0058] The detection piece is arranged such that the emitter 2 emits a light signal capable of penetrating clothing into the drum body 1, and the receiver 3 is arranged opposite to the emitter 2 to receive the light signal.

[0059] Preferably, the emitter 2 and the receiver 3 are symmetrical about the axis of the drum body 1;

[0060] In the embodiment, the emitter 2 and the receiver 3 are directly fixed on the inner wall of the cylinder body 1 through the connecting assembly 4, and the fixing mode is simple and firm. The emitter 2 emits light signals to the receiver 3. The light signals emitted by the emitter 2 pass through the clothes in the cylinder body 1. Part of the light signals is blocked and absorbed by the clothes, and the other part of the light signals penetrates the clothes and is received by the receiver 3. The penetration ability of the light signals to clothes of different materials is different. The material of the clothes in the cylinder body 1 can be judged by using the difference in the penetration ability of the light signals to clothes of different materials. The washing mode matched with the material can be selected according to the judged material, so that the clothes of different materials can be targetedly protected in the washing process.

[0061] Specifically, the number of detection pieces can be multiple, which is not limited. The emitter 2 and the receiver 3 in each detection piece are symmetric about the axis of the cylinder body 1. After the light signals emitted by the emitter 2 are emitted to the clothes, the receiver 3 is located in the transmission direction of the transmitted light signals, so that the transmitted light signals are easily received. The multiple detection pieces can form a cross light signal network in the cylinder body 1, which can comprehensively cover the clothes in the clothes treatment cylinder 4, so that the material information of the clothes can be more comprehensively obtained, and the detection of the material of the clothes by the clothes treatment cylinder is more sufficient and accurate.

[0062] More specifically, the emitter 2 and the receiver 3 are directly fixed on the inner wall of the cylinder body 1 through the connecting assembly, the fixing structure is simple and more firm, and the fixing position on the inner wall of the cylinder body 1 is more flexible. The fixing position can be selected according to the number and arrangement of the detection pieces, so that the cross light signal network which comprehensively covers the clothes is more easily formed.

[0063] For example, when the distances from the emitters 2 and the receivers 3 of the multiple detection pieces to the bottom of the cylinder body 1 are the same, the cross signal network formed by the multiple detection pieces in the cylinder body 1 is in the same vertical plane, and the signal network is relatively uniform. When the distances from the emitter 2 of at least one detection piece to the receiver 3 for receiving the light signals emitted by the emitter to the bottom of the cylinder body 1 are different, the cross signal network formed by the multiple detection pieces in the cylinder body 1 is in different vertical planes, and the signal network has a certain longitudinal depth in the cylinder body 1. The clothes in the cylinder body 1 can be comprehensively covered in the above two cases.

[0064] The emitter 2 and the receiver 3 are both powered by the wireless power supply module provided by the clothes treatment cylinder.

[0065] Optionally, in an implementation manner of the embodiment, as shown in Figures 1-5 , the emitter 2 and the receiver 3 are directly fixed on the inner wall of the cylinder body 1 through the connecting assembly 4.

[0066] The connecting assembly 4 is arranged in multiple, at least one of the connecting assembly 4 is arranged on the emitter 2, at least one of the connecting assembly 4 is arranged on the receiver 3, the inner wall of the barrel 1 is provided with a connecting hole 5 opposite to the connecting assembly 4, and the connecting assembly 4 is connected to the connecting hole 5 to fix the emitter 2 and the receiver 3.

[0067] In the embodiment, the emitter 2 and the receiver 3 are connected by the connecting assembly 4 on the back of each of the emitter 2 and the receiver 3 at the connecting hole 5 on the inner wall of the barrel 1. The connecting assembly 4 can be a hook structure or a protruding structure, and the area of the protruding part is greater than the opening area of the connecting hole 5, so that the emitter 2 and the receiver 3 can be fixed and clamped at the connecting hole 5. The emitter 2 and the receiver 3 are fixed on the inner wall of the barrel 1 by the connecting assembly 4, so that the emitter 2 and the receiver 3 can rotate with the barrel 1, and the fixing is firm and will not loosen.

[0068] Optionally, in an implementation manner of the embodiment, as shown in Figure 4 、 5 , 8,

[0069] The connecting assembly 4 comprises a first clamping piece 401 and a second clamping piece 402 arranged in sequence along the length direction of the emitter 2 or the receiver 3, and the connecting hole 5 comprises a first connecting hole 501 and a second connecting hole 502, the first clamping piece 401 is connected in the first connecting hole 501, and the second clamping piece 402 is connected in the second connecting hole 502.

[0070] In the embodiment, the connecting assembly 4 is composed of the first clamping piece 401 and the second clamping piece 402. The connecting assembly 4 located on the back of the emitter 2 is fixedly connected with the first clamping piece 401 at one end of the emitter 2 and fixedly connected with the second clamping piece 402 at the other end of the emitter 2, and the first clamping piece 401 and the second clamping piece 402 jointly fix the two ends of the emitter 2 in the corresponding first connecting hole 501 and second connecting hole 502, thereby further improving the firm fixing of the connecting assembly 4 on the emitter 2. Similarly, the connecting assembly 4 located on the back of the receiver 3 is fixedly connected with the first clamping piece 401 at one end of the receiver 3 and fixedly connected with the second clamping piece 402 at the other end of the receiver 3, and the first clamping piece 401 and the second clamping piece 402 jointly fix the two ends of the receiver 3 in the corresponding first connecting hole 501 and second connecting hole 502, thereby further improving the firm fixing of the connecting assembly 4 on the receiver 3.

[0071] Specifically, the first clamping piece 401 is provided with a first clamping hook 4011, the second clamping piece 402 is provided with a second clamping hook 4021, the first clamping hook 4011 is hooked on the outer wall of the barrel 1 through the first connecting hole 501, and the second clamping hook 4021 is hooked on the outer wall of the barrel 1 through the second connecting hole 502.

[0072] The first clamping hook 4011 is fixed to the corresponding first connecting hole 501, and the second clamping hook is fixed to the corresponding second connecting hole 502, so that the connecting assembly 4 firmly fixes the emitter 2 and the receiver 3 on the inner wall of the cylinder body 1.

[0073] More specifically, the first clamping hook 4011 is oriented in the clockwise direction along the circumference of the outer wall of the cylinder body 1, and the second clamping hook 4021 is oriented in the counterclockwise direction along the circumference of the outer wall of the cylinder body 1.

[0074] The clockwise direction specifically refers to the clockwise direction along the circumference of the outer wall of the cylinder body 1 when viewed from the cylinder mouth to the cylinder bottom of the cylinder body 1, and the counterclockwise direction specifically refers to the counterclockwise direction along the circumference of the outer wall of the cylinder body 1 when viewed from the cylinder mouth to the cylinder bottom of the cylinder body 1.

[0075] The first clamping hook 4011 and the second clamping hook 4021 are respectively fixed to different positions on the outer wall of the cylinder body 1, and the two clamping hooks are oriented in different directions, so that the connecting assembly 4 is fixedly connected to the cylinder body 1 at different positions, further improving the overall connection and firmness between the connecting assembly 4 and the inner wall of the cylinder body 1 and the emitter 2 and the receiver 3.

[0076] The first clamping hook 4011 and the second clamping hook 4021 make the first clamping piece 401 and the second clamping piece 402 into an inverted buckle structure, the back of the emitter 2 and the receiver 3 each has two inverted buckles, the two inverted buckles on the back of the emitter 2 are respectively located at the two ends of the emitter 2, and the two inverted buckles on the back of the receiver 3 are respectively located at the two ends of the receiver 3. The inverted buckles are embedded in the inner wall of the cylinder body 1 through the connecting hole 5, so that the emitter 2 and the receiver 3 are firmly fixed on the inner wall of the cylinder body 1 and are not easy to loosen, and the emitter 2 and the receiver 3 form a pair of shots. The degree of weakening of the light intensity of the light signal emitted by the emitter 2 after passing through the clothes is determined to determine the material of the clothes, and the detection piece is more accurate in detecting the material of the clothes.

[0077] Optionally, in one implementation manner of the embodiment,

[0078] The detection piece is an ultraviolet sensor, the emitter 2 is an ultraviolet sensor emitter, the receiver 3 is an ultraviolet sensor receiver, and the light signal is an ultraviolet light signal.

[0079] In the embodiment, the emitter of the ultraviolet sensor emits ultraviolet light signals with a wavelength of 100-400 nm. The 100-400 nm ultraviolet light signals emitted by the emitter pass through the clothes in the barrel 1. Part of the 100-400 nm ultraviolet light signals is blocked and absorbed by the clothes, and the other part of the 100-400 nm ultraviolet light signals penetrates the clothes and is received by the receiver 3. The 100-400 nm ultraviolet light signals have different penetration abilities for clothes made of different materials. The receiver 3 converts the received ultraviolet light signals into electrical signals. After the electrical signals are processed by the MCU chip in the processor, the electrical signals are converted into digital signals. The processor generates comparable ultraviolet data, that is, the material of the clothes in the barrel 1 can be determined. According to the determined material, a washing mode matching the material can be selected, so that different materials of clothes can be targetedly protected during the washing process.

[0080] It should be noted that the light signal can generate transmission after contacting the clothes. When the light signal generates transmission after contacting the clothes, a transmission parameter value can be obtained.

[0081] Specifically, the transmission parameter value can be a parameter value of the transmitted light signal itself after transmission, such as the light transmittance and light intensity of the transmitted light signal. Alternatively, the transmission parameter value can be obtained by calculating the parameter value of the transmitted light signal itself, such as substituting the light transmittance and / or light intensity of the transmitted light signal into a preset calculation formula. In general, as long as different clothes materials can correspond to different transmission parameter values.

[0082] In the embodiment, the preset calculation formula for calculating the transmission parameter value can be a formula containing the wavelength and light intensity of the transmitted light signal, for example, the transmission parameter value b = T% * φ light flux * power factor (related to light intensity), and the light transmittance T% = I (light intensity after transmission attenuation) / I0 (original light intensity) * 100%.

[0083] In the embodiment, in order to determine the material of the clothes, a transmission standard value interval is preset. Different transmission standard value intervals correspond to different clothes materials, that is, the transmission standard value interval and the clothes material have a corresponding relationship.

[0084] 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 values of the same type or obtained by using the same algorithm, and the difference is that the transmission standard value is a parameter value obtained by performing a transmission experiment on the clothes in the case of knowing the clothes material, while the transmission parameter value is a parameter value obtained by performing a transmission on the clothes when actually identifying the clothes material. In order to facilitate understanding, for example, in the test, the transmittance and light intensity of the transmitted light signal are calculated by using formula B to obtain the transmission standard value. After multiple tests on clothes of material b, a numerical interval Q1 can be divided according to all the obtained transmission standard values. In actual identification of the clothes material, the transmittance and light intensity of the transmitted light signal are also calculated by using formula B, that is, the transmission parameter value is obtained. Since the calculation process of the transmission parameter value is the same as that of the transmission standard value, the clothes material of the clothes can be determined according to the transmission parameter value.

[0085] The corresponding relationship between the transmission standard value interval and the clothes material is that each type of clothes material corresponds to a transmission standard value interval, and the transmission standard value intervals corresponding to different types of clothes materials are different. For example, material a corresponds to the transmission standard value interval Q1, which is the corresponding relationship. When the transmission parameter value is located in Q1, it can be determined that the clothes material of the clothes is a.

[0086] Optionally, in an implementation manner of the embodiment, as shown in Figure 2 ,

[0087] The distance between the emitter 2 and the receiver 3 is equal to the diameter of the cylinder body 1.

[0088] In the embodiment, the emitter 2 and the receiver 3 are symmetrically arranged about the axis of the cylinder body 1. This arrangement mode makes the light signal emitted by the emitter 2 directly received by the receiver 3 after being emitted to the clothes. The light signal emitted by the emitter 2 spans the entire inside of the cylinder body 1 from a transmission point on the inner wall of the cylinder body 1 to a receiving point of the receiver 3. Multiple detection pieces can form a cross light signal network in the cylinder body 1, fully covering the clothes in the clothes treatment cylinder 4, and more comprehensively obtaining the clothes material related information, so that the clothes material detection of the clothes treatment cylinder is more sufficient and accurate.

[0089] Optionally, in an implementation manner of the embodiment, as shown in Figure 1 ,

[0090] The outer sides of the emitter 2 and the receiver 3 are both provided with a protective cover 6. The protective cover 6 is transparent, and the protective cover 6 is fixedly connected with the inner wall of the cylinder body 1.

[0091] In this embodiment, the protective cover 6 is made of transparent glass, the light signal emitted by the emitter 2 can penetrate the transparent glass, the protective cover 6 does not affect the emission and reception of the light signal by the emitter 2 and the receiver 3, and the protective cover 6 plays a waterproof and dustproof effect on the emitter 2 and the receiver 3.

[0092] Preferably, the protective cover 6 is configured in a rib shape, the protective cover 6 not only plays a waterproof and dustproof effect on the emitter 2 and the receiver 3 in the cylinder 1, but also serves as a rib in the cylinder 1, and in the washing process, the protective cover 6 drives the clothes to rotate together. When the clothes are lifted to a certain height by the rib, the clothes will fall back into the washing water due to gravity, and the impact with the washing water produces a beating effect. The beating effect can further penetrate the fibers of the clothes and remove deeper stains.

[0093] Embodiment Two

[0094] The laundry treatment device provided in this embodiment comprises:

[0095] The laundry treatment cylinder in Embodiment One;

[0096] The processor is configured to obtain a first light signal intensity of the light signal emitted by the emitter 2, a second light signal intensity of the light signal received by the receiver 3, and perform data analysis according to the first light signal intensity and the second light signal intensity.

[0097] The processor can control the working state of a single detection member or multiple detection members. The processor can control multiple detection members to work simultaneously, or control at least two detection members in the multiple detection members to work simultaneously while the other detection members do not work, or control a single detection member to work while the other detection members do not work. For example, the processor controls the emitter 2 in a single detection member to emit a light signal to the clothes in the cylinder 1. When the emitted light signal is not blocked by the clothes, the light signal intensity is the first light signal intensity, which is obtained by the processor. The light signal emitted by the emitter 2 passes through the clothes in the cylinder 1, part of the light signal is blocked and absorbed by the clothes, and the other part of the light signal penetrates the clothes and is received by the receiver 3. The light signal intensity at this time is the second light signal intensity, which is obtained by the processor. The light signal has different penetration abilities for clothes made of different materials. By using the difference in the penetration abilities of the light signal for clothes made of different materials, the processor converts the obtained first light signal intensity and second light signal intensity into electrical signals and then into digital signals, compares the changes in the first light signal intensity and the second light signal intensity, and determines the material of the clothes. The detection structure is simple and accurate.

[0098] Embodiment Three

[0099] As Figure 8As shown, the embodiment provides a clothes processing method for identifying the material of clothes in the clothes processing device in Embodiment Two, which comprises the following steps.

[0100] obtaining a second light signal intensity λ2 of a second light signal, the second light signal being the light signal after the first light signal emitted by the light source penetrates the clothes;

[0101] obtaining a light signal intensity difference Δλ = λ1- λ2 according to the first light signal intensity λ1 and the second light signal intensity λ2, wherein the first light signal intensity λ1 is the intensity of the first light signal;

[0102] determining the material of the clothes according to the light signal intensity difference Δλ and the corresponding relationship between the preset difference interval and the material of the clothes.

[0103] In the embodiment, the emitter 2 emits the light signal to the clothes in the cylinder 1. When the emitted light signal is not blocked by the clothes, the intensity of the light signal is the first light signal intensity. The light signal emitted by the emitter 2 passes through the clothes in the cylinder 1, part of the light signal is blocked and absorbed by the clothes, and the other part of the light signal penetrates the clothes and is received by the receiver 3. The light signal that is blocked and transmitted by the clothes is received by the receiver 3, and the intensity of the light signal at this time is the second light signal intensity. The penetration ability of the light signal to different materials of clothes is different. By obtaining the first light signal intensity and the second light signal intensity, calculating the difference between the first light signal intensity and the second light signal intensity, determining the preset difference interval corresponding to the difference, and determining the material of the clothes according to the corresponding relationship between the preset difference interval and the material of the clothes, the clothes processing method has small order of magnitude in identifying the material of the clothes, and can achieve fast and accurate identification effect.

[0104] Optionally, in an implementation manner of the embodiment, as shown in Figure 8 ,

[0105] determining the material of the clothes according to the corresponding relationship between the light signal intensity difference Δλ and the preset difference interval, comprising:

[0106] determining the material of the clothes according to the corresponding relationship between the light signal intensity difference Δλ and the preset difference interval;

[0107] wherein the distribution state of the clothes is changed before obtaining the light signal intensity difference Δλ each time;

[0108] wherein if the light signal intensity difference Δλ obtained multiple times is in the same preset difference interval, the material of the clothes corresponding to the same preset difference interval is determined as the material of the clothes.

[0109] In this embodiment, the accuracy of the clothing material identification is improved by obtaining multiple light signal intensity difference Δλ. Before obtaining the light signal intensity difference Δλ each time, the rotation time t of the cylinder 1 is controlled, so that the clothes in the cylinder 1 are at different positions, further increasing the accuracy of the clothing material identification. When the multiple light signal intensity differences Δλ are equal to the same preset difference interval, it is determined that the clothes in the cylinder 1 are the clothing material corresponding to the preset difference interval.

[0110] Optionally, in an implementation manner of the embodiment, as shown in Figure 8

[0111] The preset difference interval includes a first preset difference interval, a second preset difference interval, and a third preset difference interval. The first preset difference interval has a first preset target value and corresponds to a first clothing material. The second preset difference interval has a second preset target value and corresponds to a second clothing material. The third preset difference interval has a third preset target value and corresponds to a third clothing material.

[0112] The clothing processing method further includes:

[0113] The light signal intensity difference Δλ = n × the first preset target value + m × the second preset target value + q × the third preset target value.

[0114] If the obtained light signal intensity difference Δλ is greater than the first preset target value, it is determined that the clothes in the cylinder 1 of the clothing processing device are n1 first clothing materials, m1 second clothing materials, and q1 third clothing materials.

[0115] Change the distribution state of the clothes.

[0116] If the obtained light signal intensity difference Δλ is less than the first preset target value and greater than the second preset target value, it is determined that the clothes in the cylinder 1 of the clothing processing device are m2 second clothing materials and q2 third clothing materials.

[0117] If the light signal intensity difference Δλ is less than the second preset target value and greater than the third preset target value, it is determined that the clothes in the cylinder 1 of the clothing processing device are q3 third clothing materials.

[0118] Wherein, when n1, m1, m2, q1, q2, q3 have decimal values, the values are rounded up to integer values.

[0119] The preset target value is a value selected from the corresponding preset difference interval, which is used for the calculation of the quantity of the clothing material. The preset target value can be an empirical value or an experimental value, and can be the average of the maximum value and the minimum value of the interval. No specific limitation is made to this.

[0120] ​With the first preset target value being 60, the corresponding clothes material being cotton, the second preset target value being 40, the corresponding clothes material being polyester fiber, and the third preset target value being 20, the corresponding clothes material being silk as an example, the light intensity emitted by the emitter 2 in the ultraviolet wavelength range of 100-400 nm is 300, and the light intensity of the ultraviolet light signal after penetrating the clothes and reaching the receiver 3 is 240, with an attenuation of 60. Δλ = λ1-λ2 = 300-240 = 60. If Δλ obtained multiple times is all 60, it is determined that the clothes in the barrel 1 are all of cotton material.

[0121] Specifically, if the obtained light signal intensity difference Δλ is greater than the first preset target value, the light signal intensity difference Δλ = n1 × first preset target value + m1 × second preset target value + q1 × third preset target value, it is determined that the clothes in the barrel 1 of the clothes processing device are n1 first clothes materials, m1 second clothes materials, and q1 third clothes materials.

[0122] Control the rotation time t of the barrel 1, and obtain the light signal intensity difference Δλ again.

[0123] If the obtained light signal intensity difference Δλ is less than the first preset target value and greater than the second preset target value, the light signal intensity difference Δλ = m2 × second preset target value + q2 × third preset target value, it is determined that the clothes in the barrel 1 of the clothes processing device are m2 second clothes materials and q2 third clothes materials.

[0124] If the light signal intensity difference Δλ is less than the second preset target value and greater than the third preset target value, the light signal intensity difference Δλ = q3 × third preset target value, it is determined that the clothes in the barrel 1 of the clothes processing device are q3 third clothes materials.

[0125] Wherein when the values of n1, m1, m2, q1, q2, q3 have decimal numbers, the values are rounded up to integers.

[0126] In this embodiment, the clothes of multiple materials in the barrel 1 may overlap at the emitter 2. For example, Δλ = λ1-λ2 = 300-200 = 100, Δλ = 100, and the following cases are exemplified:

[0127] 1. Δλ = 100 = 1 × 60 + 1 × 40 + 0 × 20. In this case, it is determined that there is one piece of cotton material clothes and one piece of polyester fiber material clothes in the barrel 1.

[0128] 2. Δλ = 100 = 0 × 60 + 1 × 40 + 3 × 20. In this case, it is determined that there are three pieces of silk material clothes and one piece of polyester fiber material clothes in the barrel 1.

[0129] 3, Δλ = 100 = 1 x 60 + 0 x 40 + 2 x 20, in this case, it is judged that there are two silk clothes and one cotton clothes in the cylinder 1;

[0130] 4, Δλ = 100 = 0 x 60 + 2 x 40 + 1 x 20, in this case, it is judged that there is one silk clothes and two polyester clothes in the cylinder 1;

[0131] After rotating the cylinder 1, for example, if the Δλ value is greater than 20 and less than 40, it can be determined that there are two silks in the cylinder 1, and the second detection result combined with the first detection result is that the clothes in the cylinder 1 are: two silk clothes and one cotton clothes;

[0132] After rotating the cylinder 1, for example, if the Δλ value is greater than 20 and less than 40, it can be determined that there are two silks in the cylinder 1, and the second detection result combined with the first detection result is that the clothes in the cylinder 1 are: two silk clothes and one cotton clothes;

[0133] When the Δλ value cannot be determined according to multiple acquisitions, the weight measurement in the clothes processing equipment can be combined with the detection result to determine the material of the clothes in the cylinder 1.

[0134] It can be understood that Δλ = n x first preset target value + m x second preset target value + q x third preset target value, that is, Δλ = n x first preset target value + m x second preset target value + q x third preset target value.

[0135] In summary, the ingenious idea of the clothes processing cylinder and the clothes processing method is:

[0136] First, the difference in the penetration ability of light signals for different materials can be used to determine the material of the clothes in the cylinder, and the determined material can be selected to match the washing mode, so as to realize targeted protection of different materials in the washing process. The emitter and the receiver are directly fixed on the inner wall of the cylinder through the connecting assembly, the fixed structure is simple and more firm, the fixed position on the inner wall of the cylinder is more flexible, the fixed position can be selected according to the number and arrangement of the detection pieces, and the light signal net which is fully covered and crossed by the clothes is more easily formed.

[0137] Secondly, the transmitting pole and the receiving pole are connected at the connecting holes on the inner wall of the cylinder through the connecting components on the back of each pole, the connecting components can be hook-shaped structures or protruding structures, the area of the protruding part is larger than the opening area of the connecting hole, so that the transmitting pole and the receiving pole can be fixed and clamped at the connecting hole. The connecting components are used to fix the transmitting pole and the receiving pole on the inner wall of the cylinder, so that the transmitting pole and the receiving pole can rotate with the cylinder, and the fixing is firm and will not loosen.

[0138] Thirdly, the first clamping hook and the second clamping hook make the first clamping piece and the second clamping piece into an inverted buckle structure, the back of the transmitting pole and the back of the receiving pole are respectively provided with two inverted buckles, the two inverted buckles on the back of the transmitting pole are respectively located at the two ends of the transmitting pole, the two inverted buckles on the back of the receiving pole are respectively located at the two ends of the receiving pole, and the inverted buckles are embedded in the inner wall of the cylinder through the connecting holes, so that the transmitting pole and the receiving pole are firmly fixed on the inner wall of the cylinder and are not easy to loosen, the transmitting pole and the receiving pole form a pair of shots, and the degree of weakening of the light intensity of the light signal emitted by the transmitting pole after passing through the clothes is determined to determine the material of the clothes, and the detection piece can more accurately detect the material of the clothes.

[0139] Fourthly, the first light signal intensity and the second light signal intensity are obtained, the difference between the first light signal intensity and the second light signal intensity is calculated, the preset target value corresponding to the difference is determined, and then the material of the clothes is determined according to the corresponding relationship between the preset target value and the material of the clothes. The clothes processing method has a small order of magnitude in identifying the material of the clothes, can achieve a fast and accurate identification effect, and the relationship between the difference in light signal intensity and the preset target value can be designed to further accurately determine the case where multiple materials exist at the same time.
