Description

Technical Field

[0001] This invention relates to the field of garment processing equipment technology, and in particular to a material testing method, a material testing device, an electronic device, and a garment processing device. Background Technology

[0002] In clothing material detection technologies, camera sampling technology is generally used. Smart camera identification of clothing material is a technology that integrates image recognition technology, deep learning algorithms and expert systems. However, camera sampling technology relies on deep learning algorithms and expert systems to determine clothing material, resulting in low accuracy in clothing material detection. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing methods for detecting clothing materials have low accuracy, and the invention provides a material detection method, a material detection device, an electronic device, and a clothing processing device.

[0004] This invention aims to provide a material detection method for identifying the material of clothing inside a clothing processing drum of a clothing processing device. Multiple optical signal detection devices are installed at different positions inside the clothing processing drum. These optical signal detection devices can acquire multiple diffuse reflection parameter values ​​when the clothing diffusely reflects incident light signals. Furthermore, the distance between the optical signal detection devices and the clothing inside the clothing processing drum is adjustable. The material detection method includes:

[0005] Parameter acquisition steps: Obtain the first parameter range corresponding to each of the plurality of optical signal detection devices, wherein the first parameter range is determined based on the plurality of diffuse reflection parameter values;

[0006] Judgment and processing steps:

[0007] Determine whether there is an overlapping range in the first parameter intervals corresponding to each of the plurality of optical signal detectors. If at least two optical signal detectors have overlapping first parameter intervals, adjust the distance between at least one of the at least two optical signal detectors and the clothes in the clothes processing drum, and repeat the parameter acquisition step and the determination process.

[0008] If the first parameter intervals corresponding to the plurality of optical signal detectors do not overlap, the clothing material is determined based on the plurality of diffuse reflection parameter values ​​corresponding to the plurality of optical signal detectors.

[0009] In some embodiments, when adjusting the distance between at least one of the at least two optical signal detection devices and the clothes in the clothing processing drum, the overlapping interval is compared with a preset overlapping interval. The larger the difference between the maximum and minimum values ​​of the overlapping interval is compared with the difference between the maximum and minimum values ​​of the preset overlapping interval, the greater the distance between the optical signal detection device and the clothes in the clothing processing drum is adjusted.

[0010] In some embodiments, obtaining the first parameter range corresponding to each of the plurality of optical signal detectors includes:

[0011] The optical signal detection device is controlled to repeatedly acquire optical signals multiple times. Each optical signal corresponds to a first parameter value. The minimum and maximum values ​​are selected from multiple first parameter values ​​to determine the first parameter range.

[0012] In some embodiments, the number of optical signal detection devices is n, n≥2, and the n optical signal detection devices are sequentially distributed along the circumference of the clothing processing drum in the clothing processing device. Each optical signal detection device includes an emitter and a receiver.

[0013] The parameter acquisition step and / or the judgment processing step include: controlling the emitter of any one of the n optical signal detectors to emit an optical signal to the clothes in the clothes processing drum, and controlling the receiver of any one of the optical signal detectors to receive the optical signal reflected from the clothes in the clothes processing drum.

[0014] In some embodiments, n=3, and the three optical signal detectors are a first optical signal detector, a second optical signal detector, and a third optical signal detector;

[0015] The first optical signal detector is controlled to acquire a first parameter range A, the second optical signal detector is controlled to acquire a first parameter value B, and the third optical signal detector is controlled to acquire a first parameter range C.

[0016] If there are overlapping intervals between the first parameter interval A, the second parameter interval B, and the third parameter interval C, then the distance between the first optical signal detector, the second optical signal detector, and the third optical signal detector and the clothes in the clothes processing drum is adjusted to be equal, or the distance between at least one of the three optical signal detectors and the clothes in the clothes processing drum is adjusted to a preset distance a.

[0017] If there is an overlapping interval between the first parameter interval A, the second parameter interval B, and the third parameter interval C, then adjust the distance between one of the three optical signal detectors and the clothes in the clothes processing drum to a preset distance a.

[0018] The preset overlapping intervals include a first preset overlapping interval, a second preset overlapping interval, a third preset overlapping interval, and a fourth preset overlapping interval. The minimum value of the second preset overlapping interval is greater than the maximum value of the first preset overlapping interval, the minimum value of the third preset overlapping interval is greater than the maximum value of the second preset overlapping interval, and the minimum value of the fourth preset overlapping interval is greater than the maximum value of the third preset overlapping interval.

[0019] If there are overlapping intervals between the first parameter interval A, the second parameter interval B, and the third parameter interval C, and all the overlapping intervals are located within the fourth preset overlapping interval, then the distances between the first optical signal detector, the second optical signal detector, and the third optical signal detector and the clothes in the clothes processing drum are all adjusted to a preset distance a.

[0020] If there are overlapping intervals between the first parameter interval A, the second parameter interval B, and the third parameter interval C, and all the overlapping intervals are located within the third preset overlapping interval, then the distance between the first optical signal detector and / or the second optical signal detector and the clothes in the clothes processing drum is adjusted to a preset distance a.

[0021] If there are overlapping intervals between the first parameter interval A, the second parameter interval B, and the third parameter interval C, and all the overlapping intervals are located within the second preset overlapping interval, then the distances between the first optical signal detector, the second optical signal detector, and the third optical signal detector and the clothes in the clothes processing drum are all adjusted to a preset distance b.

[0022] In some embodiments, if there are overlapping intervals between the first parameter interval A, the second parameter interval B, and the third parameter interval C, and all the overlapping intervals are located within the first preset overlapping interval, then the distances between the first optical signal detector, the second optical signal detector, and the third optical signal detector and the clothes in the clothes processing drum are all adjusted to a preset distance c.

[0023] Among them, the preset distance a > preset distance b > preset distance c.

[0024] In some embodiments, the first preset overlap interval is 0 to 20, the second preset overlap interval is 21 to 40, the third preset overlap interval is 41 to 60, and the fourth preset overlap interval is 61 to 430;

[0025] Preset distance a = 20mm, preset distance b = 15mm, preset distance c = 10mm.

[0026] In some embodiments, the determination process step, which determines the clothing material based on the multiple diffuse reflection parameter values ​​corresponding to each of the multiple optical signal detectors, includes:

[0027] The multiple optical signal detectors are controlled to repeatedly acquire optical signals multiple times. Each optical signal corresponds to a second sub-parameter value. The average value of the multiple second sub-parameter values ​​acquired by each optical signal detector is calculated to obtain multiple second parameter values. The clothing material is determined based on the preset target intervals corresponding to the multiple second parameter values ​​and the clothing material corresponding to the preset target intervals.

[0028] In some embodiments, a material testing device is provided, disposed inside the garment processing drum of a garment processing device, comprising:

[0029] There are n optical signal detection devices, each of which includes an emitter and a receiver, where n ≥ 2;

[0030] The n optical signal detectors are configured such that the emitter of any one of the n optical signal detectors emits an optical signal into the clothes in the clothes processing drum, and the receiver of any one of the optical signal detectors receives the optical signal reflected from the clothes in the clothes processing drum.

[0031] There are n lifting ribs, each corresponding to one of the n optical signal detection devices. The emitter and receiver in the same optical signal detection device are laid flat on the corresponding lifting ribs.

[0032] A driving component, which is connected to the optical signal detection component for driving the optical signal detection component to move and adjust the distance between the optical signal detection component and the clothes in the clothes processing drum.

[0033] In some embodiments, the optical signal detection device is an ultraviolet sensor, the emitter is the emitter of the ultraviolet sensor, and the receiver is the receiver of the ultraviolet sensor.

[0034] In some embodiments, an electronic device is provided, the electronic device comprising:

[0035] Memory stores computer instructions;

[0036] The processor is used to invoke and execute the computer instructions to implement the above-described material detection method, or to invoke and execute the computer instructions to control the above-described material detection device and implement the above-described material detection method.

[0037] In some embodiments, a garment processing apparatus is provided, which uses the above-described material detection method, or includes the above-described material detection apparatus, or includes the above-described electronic equipment.

[0038] The solution provided by this invention has the following advantages compared with the prior art:

[0039] By gradually adjusting the distance between the optical signal detector and the clothing, a suitable distance is achieved. This reduces the overlap in clothing material detection, improves the accuracy of material detection, ensures the validity of subsequent parameter values, reduces the number of repeated detections, and shortens the time required for clothing material detection, resulting in accurate and efficient clothing material detection.

Obviously, the drawings described below are merely some embodiments, and those skilled in the art can obtain other drawings based on these drawings without creative effort. In the drawings:

Therefore, they should not be construed as limiting this invention.

[0044] 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.

[0045] In clothing material detection technologies, camera sampling technology is generally used. Smart camera identification of clothing material is a technology that integrates image recognition technology, deep learning algorithms and expert systems. However, camera sampling technology relies on deep learning algorithms and expert systems to determine clothing material, resulting in low accuracy in clothing material detection.

[0046] Based on this, the following embodiments are proposed.

[0047] Example 1:

[0048] like Figure 1 As shown, this embodiment provides a material detection method for identifying the material of clothing inside the clothing processing drum of a clothing processing device. Multiple optical signal detection devices are installed at different positions inside the clothing processing drum. These optical signal detection devices can acquire multiple diffuse reflection parameter values ​​when the clothing diffusely reflects the incident light signal. Furthermore, the distance between the optical signal detection devices and the clothing inside the clothing processing drum is adjustable. The material detection method includes:

[0049] Parameter acquisition steps: Obtain the first parameter range corresponding to each of the multiple optical signal detection devices. The first parameter range is determined based on multiple diffuse reflection parameter values.

[0050] Judgment and processing steps:

[0051] Determine whether there are overlapping intervals in the first parameter intervals corresponding to multiple optical signal detection devices.

[0052] If at least two optical signal detectors have overlapping first parameter ranges, then adjust the distance between at least one of the two optical signal detectors and the clothes in the clothes processing drum, and repeat the parameter acquisition and judgment processing steps.

[0053] If the first parameter intervals corresponding to the multiple optical signal detectors do not overlap, the clothing material is determined based on the multiple diffuse reflection parameter values ​​corresponding to the multiple optical signal detectors.

[0054] In this embodiment, the method for detecting clothing material consists of a parameter acquisition step and a judgment processing step. In the parameter acquisition step, multiple first parameter intervals are acquired. In the judgment processing step, it is determined whether there are overlapping intervals among the multiple first parameter intervals. If at least two optical signal detectors have overlapping first parameter intervals, it will lead to inaccurate clothing material detection. By adjusting the distance between the optical signal detector and the clothing, the probability of overlapping of multiple first parameter intervals is reduced. When there are no overlapping intervals among the first parameter intervals, the degree of overlap in clothing material detection is reduced. This material detection method, by gradually adjusting the distance between the optical signal detector and the clothing as described above, ensures that there is a suitable distance between the optical signal detector and the clothing. This reduces the degree of overlap in clothing material detection, improves the accuracy of material detection, ensures the validity of subsequent parameter values, reduces the number of repeated detections, and reduces the time required for clothing material detection, making clothing material detection accurate and efficient.

[0055] One method for adjusting the distance between the optical signal detector and the clothing is as follows: The optical signal detector is placed inside a lifting rib. Taking the lifting rib as an example, which is applied to the processing drum of a clothing processing device, the lifting rib includes a lifting rib body and a support plate. The lifting rib body has a convex wall protruding from the inner wall of the processing drum into the interior of the processing drum, and an installation space formed inside the convex wall. The support plate is movably disposed within the installation space, and a detector for optical signal detection is disposed on the support plate. The convex wall has a light-transmitting portion at least in the part opposite to the detector for the detector to perform optical signal detection. The extension direction of the convex wall formed by the lifting rib body is taken as the height direction of the lifting rib body. The installation space is formed inside the convex wall. The installation space and the interior of the processing drum can be two separate spaces or connected spaces. The support plate is located within the installation space and can move. The support plate moves along the height direction of the lifting rib body and can reciprocate within the installation space along the height direction of the lifting rib body, thereby driving the detector to reciprocate along the height direction of the lifting rib body, thus gradually adjusting the distance between the optical signal detector and the clothing. In this embodiment, the distance between the optical signal detection device and the clothing can be the distance between the lifting rib and the upper edge of the convex wall.

[0056] Those skilled in the art should understand that, in one embodiment of this application, when the optical signal detection device is disposed inside the lifting rib, the distance between the optical signal detection device and the clothing essentially depends on the direction of optical signal emission and reception of the optical signal detection device and the distance between the optical signal detection device and the outer wall of the lifting rib (the side wall in contact with the clothing).

[0057] Alternatively, in one implementation of this embodiment,

[0058] When adjusting the distance between at least one of the at least two optical signal detection devices and the clothes in the clothing processing drum, the overlapping interval is compared with a preset overlapping interval. The greater the difference between the maximum and minimum values ​​of the overlapping interval compared with the difference between the maximum and minimum values ​​of the preset overlapping interval, the greater the distance between the optical signal detection device and the clothes in the clothing processing drum.

[0059] In this embodiment, the larger the difference between the maximum and minimum values ​​of the overlapping interval is compared to the difference between the maximum and minimum values ​​of the preset overlapping interval, the greater the likelihood that the multiple first parameter intervals have a large overlap range. In this case, by adjusting the distance between the optical signal detection device and the clothing to a large extent, the multiple first parameter intervals can be made to have no overlapping intervals in the fastest way, thereby achieving faster adjustment of the optical signal detection device.

[0060] Optionally, in one implementation of this embodiment, such as Figure 1 As shown,

[0061] The step of obtaining the first parameter range corresponding to each of the plurality of optical signal detectors includes:

[0062] The optical signal detection device is controlled to repeatedly acquire optical signals multiple times. Each optical signal corresponds to a first parameter value. The minimum and maximum values ​​are selected from multiple first parameter values ​​to form the first parameter interval.

[0063] In this embodiment, multiple first parameter values ​​are obtained by repeatedly acquiring optical signals through an optical signal detection device. The minimum and maximum values ​​are selected from the multiple first parameter values ​​to form a first parameter interval. Among the multiple first parameter values, the minimum and maximum values ​​are used as the end values ​​of the first parameter interval, making the first parameter interval more accurate. This also makes the overlapping intervals obtained by comparing the multiple first parameter intervals pairwise more accurate.

[0064] Alternatively, in one implementation of this embodiment,

[0065] The number of optical signal detection devices is n, n≥2. The n optical signal detection devices are distributed sequentially along the circumference of the clothing processing drum in the clothing processing equipment. Each optical signal detection device includes an emitter and a receiver.

[0066] The parameter acquisition step and / or judgment processing step include: controlling the emitter of any one of the n optical signal detection devices to emit an optical signal to the clothes in the clothes processing drum, and controlling the receiver of any one of the optical signal detection devices to receive the optical signal reflected from the clothes in the clothes processing drum.

[0067] In this embodiment, n=3, and three optical signal detectors are arranged in a ring inside the clothing processing drum to perform multi-angle detection on the clothing inside the clothing processing drum. Each optical signal detector is responsible for acquiring a parameter value range. Based on the comparison between the three first parameter ranges, three overlapping ranges are obtained. The three overlapping ranges are compared with the preset overlapping range, and the distance between the optical signal detector and the clothing is adjusted so that there is a suitable distance between the optical signal detector and the clothing.

[0068] The three-light signal detection device includes a first light signal detector, a second light signal detector, and a third light signal detector. The first light signal detector includes a first emitter and a first receiver; the second light signal detector includes a second emitter and a second receiver; and the third light signal detector includes a third emitter and a third receiver.

[0069] Obtaining multiple first parameter ranges involves controlling a first, second, and third emitter to emit light signals to the clothing in the clothing processing device; controlling a first receiver to receive the light signals emitted by the first emitter reflected by the clothing in the clothing processing drum; controlling a second receiver to receive the light signals emitted by the second emitter reflected by the clothing in the clothing processing drum; and controlling a third receiver to receive the light signals emitted by the third emitter reflected by the clothing in the clothing processing drum. The light signals emitted by the emitters pass through the clothing in the clothing processing drum. Part of the light signal is blocked and reflected by the clothing and received by the corresponding receiver; part of the light signal is absorbed by the clothing; and another part of the light signal penetrates the clothing. Different clothing materials have different reflectivity of light signals. Therefore, different first parameter values ​​can be obtained for different clothing materials. The first parameter values ​​are then filtered to obtain the first parameter range. This method is simple, easy to implement, and highly accurate.

[0070] Specifically, the first optical signal detection device is controlled to repeatedly acquire the first optical signal multiple times. Each first optical signal corresponds to a first parameter value A. The minimum and maximum values ​​of the multiple first parameter values ​​A are selected to form the first parameter interval A.

[0071] The second optical signal detection device is controlled to repeatedly acquire the second optical signal multiple times. Each second optical signal corresponds to a first parameter value B. The minimum and maximum values ​​of the multiple first parameter values ​​B are selected to form the first parameter interval B.

[0072] The third optical signal detection device is controlled to repeatedly acquire the third optical signal multiple times. Each third optical signal corresponds to a first parameter value C. The minimum and maximum values ​​of the multiple first parameter values ​​C are selected to form the first parameter interval C.

[0073] The overlapping intervals include a first overlapping interval, a second overlapping interval, and a third overlapping interval. The first overlapping interval is the overlapping interval of the first parameter interval A and the first parameter interval B. The second overlapping interval is the overlapping interval of the first parameter interval A and the first parameter interval C. The third overlapping interval is the overlapping interval of the first parameter interval B and the first parameter interval C.

[0074] More specifically, the preset overlapping intervals include a first preset overlapping interval, a second preset overlapping interval, a third preset overlapping interval, and a fourth preset overlapping interval. The first preset overlapping interval is 0 to 20, the second preset overlapping interval is 21 to 40, the third preset overlapping interval is 41 to 60, and the fourth preset overlapping interval is 61 to 430.

[0075] If the first overlapping interval is located within the fourth preset overlapping interval, the second overlapping interval is located within the fourth preset overlapping interval, and the third overlapping interval is located within the fourth preset overlapping interval, then adjust the distance between the first optical signal detector and the clothes in the clothes processing tube to increase to a preset distance a, adjust the distance between the second optical signal detector and the clothes in the clothes processing tube to increase to a preset distance a, and adjust the distance between the third optical signal detector and the clothes in the clothes processing tube to increase to a preset distance a.

[0076] If the first overlapping interval is located within the third preset overlapping interval, the second overlapping interval is located within the third preset overlapping interval, and the third overlapping interval is located within the third preset overlapping interval, then adjust the distance between the first optical signal detector and the clothes in the clothes processing drum to increase to a preset distance a and / or control the distance between the second optical signal detector and the clothes in the clothes processing drum to increase to a preset distance a.

[0077] If the first overlapping interval is located within the second preset overlapping interval, the second overlapping interval is located within the second preset overlapping interval, and the third overlapping interval is located within the second preset overlapping interval, then adjust the distance between the first optical signal detector and the clothes in the clothes processing tube to increase to a preset distance b, adjust the distance between the second optical signal detector and the clothes in the clothes processing tube to increase to a preset distance b, and adjust the distance between the third optical signal detector and the clothes in the clothes processing tube to increase to a preset distance b.

[0078] If the first overlapping interval is located within the first preset overlapping interval, the second overlapping interval is located within the first preset overlapping interval, and the third overlapping interval is located within the first preset overlapping interval, then the distance between the first optical signal detector and the clothes in the clothes processing drum is increased to a preset distance c; the distance between the second optical signal detector and the clothes in the clothes processing drum is increased to a preset distance c; and the distance between the third optical signal detector and the clothes in the clothes processing drum is increased to a preset distance c.

[0079] Preset distance a > Preset distance b > Preset distance c.

[0080] Among them, the preset distance a = 20mm, the preset distance b = 15mm, and the preset distance c = 10mm.

[0081] In this embodiment, if the first overlapping interval, the second overlapping interval, and the third overlapping interval are all located between 61 and 430, then in this state, the first parameter intervals A, B, and C all have large overlap intervals. Adjusting the distance between the first optical signal detector and the clothes in the clothes processing drum to 20mm, adjusting the distance between the second optical signal detector and the clothes in the clothes processing drum to 20mm, and adjusting the distance between the third optical signal detector and the clothes in the clothes processing drum to 20mm reduces the probability of multiple first parameter intervals overlapping. When there are no overlapping intervals in the first parameter intervals, then... The overlap of clothing material detection is reduced, thus improving the accuracy of material detection. At this time, the preset target ranges corresponding to each material are: cotton 100-130, linen 135-155, wool 190-230, silk 165-189, polyester 290-330, and chemical fiber 335-390. When the distance between the three optical signal detection devices and the clothing is 20mm, the preset target range range corresponding to each material is narrower, and the overlap of multiple first parameter ranges is reduced, that is, the overlap of clothing material detection is reduced, thus improving the accuracy of clothing material detection.

[0082] If the first overlapping interval is located between 41 and 60, the second overlapping interval and the third overlapping interval are all located between 41 and 60. In this state, the first parameter interval A, the first parameter interval B and the first parameter interval C have a large overlap interval with each other. The distance between the first optical signal detection device and the clothes in the clothes processing drum can be adjusted to increase to 20 mm, or the distance between the first optical signal detection device and the second optical signal detection device and the clothes in the clothes processing drum can be adjusted to increase to 20 mm.

[0083] If the first, second, and third overlap intervals are all within the range of 21 to 40, then the overlap between the first parameter intervals A, B, and C is relatively small. The distance between the first optical signal detector and the clothing in the clothing processing drum can be increased to 15mm, the distance between the second and third optical signal detectors can be increased to 15mm, and the preset target intervals for each material are as follows: cotton 80–150, linen 115–175, wool 170–250, silk 145–209, polyester 270–350, and synthetic fiber 315–410. This ensures a low degree of overlap in clothing material detection while increasing the range of preset target intervals for each material, improving the effectiveness of subsequent parameter values, reducing the number of repeated detections, and decreasing the time required for clothing material detection, resulting in accurate and efficient clothing material detection.

[0084] If the first, second, and third overlap intervals are all within the range of 0 to 20, the overlap between the first parameter intervals A, B, and C is very small. The distance between the first optical signal detector and the clothing in the processing drum can be increased to 10mm, the distance between the second and third optical signal detectors can be increased to 10mm, and the preset target intervals for each material are: cotton 60–170, linen 95–195, wool 150–280, silk 125–229, polyester 250–370, and synthetic fiber 295–430. This ensures a low degree of overlap in clothing material detection while increasing the range of preset target intervals for each material, improving the effectiveness of subsequent parameter values, reducing the number of repeated detections, and decreasing the time required for clothing material detection, resulting in accurate and efficient clothing material detection.

[0085] Optionally, in one implementation of this embodiment, such as Figure 1 As shown,

[0086] In the determination and processing step, the clothing material is determined based on the multiple diffuse reflection parameter values ​​corresponding to each of the multiple optical signal detection devices, including:

[0087] Determining the clothing material based on multiple diffuse reflection parameter values ​​corresponding to multiple optical signal detectors includes controlling multiple optical signal detectors to repeatedly acquire optical signals multiple times. Each optical signal corresponds to a second sub-parameter value. The average value of the multiple second sub-parameter values ​​acquired by each optical signal detector is calculated to obtain multiple second parameter values. The clothing material is determined based on the preset target range corresponding to the multiple second parameter values ​​and the clothing material corresponding to the preset target range.

[0088] In this embodiment, the second parameter value is obtained by calculating the average of multiple second sub-parameter values, which can further improve the accuracy of the second parameter value, determine the preset target interval in which the second parameter value is located, and finally determine the clothing material based on the correspondence between the preset target interval and the clothing material.

[0089] Example 2

[0090] This embodiment provides a material testing device, which is installed inside the garment processing drum of a garment processing device, including:

[0091] There are n optical signal detection devices, each of which includes an emitter and a receiver, where n ≥ 2;

[0092] The n optical signal detectors are configured such that the emitter of any one of the n optical signal detectors emits an optical signal into the clothes in the clothes processing drum, and the receiver of any one of the optical signal detectors receives the optical signal reflected from the clothes in the clothes processing drum.

[0093] There are n lifting ribs, and each of the n lifting ribs corresponds to one of the n optical signal detection devices. The emitter and receiver in the same optical signal detection device are laid flat on the corresponding lifting ribs.

[0094] A driving component, which is connected to a light signal detection component for driving the light signal detection component to move and adjust the distance between the light signal detection component and the clothes in the clothes processing drum.

[0095] In this embodiment, n=3, and the three optical signal detection devices include a first optical signal detection device, a second optical signal detection device, and a third optical signal detection device. The first optical signal detection device includes a first emitter and a first receiver; the second optical signal detection device includes a second emitter and a second receiver; and the third optical signal detection device includes a third emitter and a third receiver.

[0096] Obtaining the first parameter range corresponding to each of the multiple optical signal detection devices includes controlling the first, second, and third emitters to emit optical signals to the clothes in the clothing processing device; controlling the first receiver to receive the optical signals emitted by the first emitter reflected by the clothes in the clothing processing drum; controlling the second receiver to receive the optical signals emitted by the second emitter reflected by the clothes in the clothing processing drum; and controlling the third receiver to receive the optical signals emitted by the third emitter reflected by the clothes in the clothing processing drum. The optical signals emitted by the emitters pass through the clothes in the clothing processing drum. Part of the optical signal is blocked and reflected by the clothes and received by the corresponding receiver; part of the optical signal is absorbed by the clothes; and another part of the optical signal penetrates the clothes. Different materials of clothing have different reflectivity of optical signals. Therefore, different first parameter values ​​can be obtained when the clothing material is different. The first parameter values ​​are then filtered to obtain the first parameter range.

[0097] Determining the clothing material based on multiple diffuse reflection parameter values ​​corresponding to multiple optical signal detectors includes obtaining the final second parameter value by taking the mean or median. The above method of obtaining the second parameter value that characterizes the clothing is simple, easy to implement, and highly accurate.

[0098] The driving components may include a drive motor, a lead screw, a push block, and gears. The drive motor drives the gears to rotate, which in turn rotates the lead screw. The rotation of the lead screw forces the push block to move, which in turn moves the optical signal detection component. By moving the optical signal detection component toward the surface of the lifting rib, the distance between the optical signal detection component and the surface of the lifting rib is reduced, as is the distance between the optical signal detection component and the clothing. Similarly, by moving the optical signal detection component away from the surface of the lifting rib, the distance between the optical signal detection component and the surface of the lifting rib is increased, as is the distance between the optical signal detection component and the clothing. Thus, this material detection equipment can reduce the overlap of clothing material detection by adjusting the distance between the optical signal detection component and the clothing, thereby improving the accuracy of clothing material detection, ensuring the validity of the second parameter value, reducing the number of repeated detections, and reducing the time required for clothing material detection, making clothing material detection accurate and efficient.

[0099] Alternatively, in one implementation of this embodiment,

[0100] The optical signal detection device is an ultraviolet sensor, with the emitter being the ultraviolet sensor's emitter and the receiver being the ultraviolet sensor's receiver.

[0101] When the optical signal detection device is an ultraviolet sensor, the emitter is the ultraviolet sensor emitter, and the wavelength of the emitted optical signal is 100-400nm.

[0102] 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.

[0103] 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.

[0104] 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).

[0105] 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.

[0106] 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.

[0107] 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 the diffuse reflectance standard value range P1; this is the correspondence. Therefore, when the diffuse reflectance parameter value is within P1, it can be determined that the clothing material is 'a'.

[0112] This electronic device reduces the overlap of clothing material detection by adjusting the distance between the optical signal detector and the clothing, thereby improving the accuracy of clothing material detection. It also ensures the validity of the second parameter value, reduces the number of repeated detections, and reduces the time required for clothing material detection, making clothing material detection accurate and efficient.

[0113] Example 4

[0114] This embodiment provides a garment processing device. The garment processing device uses the material detection method in Embodiment 1, or includes the material detection device in Embodiment 2, or includes the electronic device in Embodiment 3.

[0115] The garment processing equipment is a washing machine.

[0116] In summary, the ingenious design of the material testing method lies in:

[0117] The method for detecting clothing materials consists of a parameter acquisition step and a judgment and processing step. In the parameter acquisition step, the distance between the optical signal detector and the clothing is gradually adjusted to ensure that there is a suitable distance between them. This reduces the overlap of clothing material detection, improves the accuracy of material detection, ensures the validity of subsequent parameter values, reduces the number of repeated detections, and reduces the time required for clothing material detection, making the detection of clothing materials accurate and efficient.
