Description

Technical Field

[0001] The present application relates to the field of material identification, and more specifically, to a method for detecting water stains on lifting ribs, a method for identifying clothing materials, and clothing processing equipment. Background Art

[0002] With the development of technology and the increase in user demand, the processing accuracy of clothing processing equipment has also improved. Taking washing machines as an example, current washing machines usually identify the material of clothes before processing them, so that clothes of different materials can use different processing parameters, which helps to improve the processing effect of clothes.

[0003] At present, material recognition mostly relies on cameras and other photographic devices, which use image algorithms to identify the material of clothing through the captured clothing images. However, in actual use, clothing not only easily blocks the camera, but also easily forms water mist or fails to automatically focus, resulting in poor clarity of the captured clothing images, which reduces the accuracy of clothing detection. Summary of the invention

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

[0005] According to a first aspect of an embodiment of the present application, a method for detecting water stains on a lifting rib is provided, wherein a receiving groove is provided on the lifting rib, a light detecting element for detecting clothing is provided in the receiving groove, a light transmitting portion covering the receiving groove is provided on the lifting rib, and a light signal emitted by the light detecting element can pass through the light transmitting portion to illuminate clothing, the method comprising:

[0006] Controlling the light detection element in the lifting rib to detect the clothing at a target position based on diffuse reflection of a light signal, and obtaining a first diffuse reflection parameter value of the light detection element corresponding to the target position;

[0007] A detection result indicating the presence or absence of water stains is generated according to a matching condition between the first diffuse reflection parameter value and a preset target parameter interval, wherein the target parameter interval is used to determine whether there is water stains on the light-transmitting portion.

[0008] By adopting this embodiment, the light detection element is controlled to detect and obtain a first diffuse reflection parameter value, and the first diffuse reflection parameter value is compared with the target parameter interval. It can be identified whether the light detection element is blocked by water stains based on the matching situation of the first diffuse reflection parameter value and the target parameter interval, which is beneficial for timely removal of water stains when there is water stains, thereby improving the detection accuracy of the light detection element when detecting clothes.

[0009] In combination with the first aspect, in an optional implementation of the embodiment of the present application, there are multiple lifting ribs, and the light detection element in each lifting rib corresponds to a corresponding first diffuse reflection parameter value;

[0010] The generating a detection result indicating the presence or absence of water stains according to a matching condition between the first diffuse reflection parameter value and a preset target parameter interval includes:

[0011] Determining whether a first diffuse reflection parameter value corresponding to at least one light detection element in the lifting rib is within the target parameter range;

[0012] If yes, then the detection result is water stains;

[0013] If not, the detection result is no water stain.

[0014] By adopting this implementation method, if the first diffuse reflection parameter value is within the target parameter range, it proves that the light detection element not covered by clothes is blocked by water stains. Conversely, if the first diffuse reflection parameter value is not within the target parameter range, it proves that no light detection element is blocked by water stains. This judgment method is conducive to ensuring the accuracy of the detection results, and the amount of calculation is small, thereby reducing the occupation of computing resources.

[0015] In combination with the first aspect, in an optional implementation of the embodiment of the present application, a plurality of the lifting ribs are arranged in the processing cylinder;

[0016] The method further comprises:

[0017] If the detection result is that there is no water stain, the number of rotations of the treatment drum for changing the target position is obtained and it is determined whether the number of rotations is less than a set number. If so, the treatment drum is controlled to rotate to change the position of the light detection element, and after the treatment drum stops rotating, the light detection elements in each of the lifting ribs are controlled to detect the clothes based on diffuse reflection of the light signal to obtain a first diffuse reflection parameter value corresponding to each of the light detection elements;

[0018] If the detection result shows that there is water stain, the drying process will be started.

[0019] By adopting the present implementation method, if the light detection element is not blocked by water stains, the processing drum can be rotated to change the position of the light detection element, so that the re-executed detection of the first diffuse reflection parameter value can continue to detect the blockage of other light detection elements; on the contrary, if the first diffuse reflection parameter value is within the target parameter range, it proves that the light detection element is blocked by water stains. At this time, starting the drying process can easily remove the water stains blocking the light detection element. After the water stains are removed, the subsequent use of the light detection element to identify clothes is not easily disturbed by the water stains, thereby improving the accuracy of recognition.

[0020] In combination with the first aspect, in an optional implementation of the embodiment of the present application, after determining whether the number of rotations is less than the number of lifting ribs, the method further includes:

[0021] When the number of rotations of the processing cylinder is equal to the set number of times, the detection result is generated based on the first diffuse reflection parameter value corresponding to each of the light detection components obtained by the last detection.

[0022] With this implementation, when the number of rotations reaches the set number, it proves that there may be only one light detection element that is blocked and has not been detected. Therefore, performing the last detection is beneficial to improving the efficiency of identifying whether the light detection element is blocked, thereby improving the efficiency of subsequent use of the light detection element to identify clothing.

[0023] In combination with the first aspect, in an optional implementation of the embodiment of the present application, controlling the processing cylinder to rotate includes:

[0024] The processing cylinder is controlled to rotate to a target angle, wherein the target angle is a preset value or the target angle is related to the number of the lifting ribs, and the more the number of the lifting ribs is, the smaller the target angle is.

[0025] With this implementation, the target angle is a preset angle, which helps to reduce the amount of calculation when controlling the rotation of the processing tube according to the target angle, thereby reducing the occupation of computing resources. When the target angle is not preset, the target angle is automatically calculated according to the number of light detection elements. When the calculated target angle is used to control the rotation of the processing tube, it is easy to ensure that at least one light detection element is not covered by clothing. At this time, the light detection element not covered by clothing can be detected, thereby ensuring that the occlusion of all light detection elements can be detected.

[0026] In combination with the first aspect, in an optional implementation of the embodiment of the present application, each of the light detection elements corresponds to a plurality of the target positions and further corresponds to a plurality of first diffuse reflection parameter values;

[0027] The generating a detection result indicating the presence or absence of water stains according to a matching condition between the first diffuse reflection parameter value and a preset target parameter interval includes:

[0028] Calculating an average value of a plurality of first diffuse reflection parameter values ​​corresponding to each of the light detection elements;

[0029] If the average value corresponding to at least one of the light detecting elements is within the target parameter range, the step of controlling the processing drum to rotate is performed; otherwise, the step of starting the drying process is performed.

[0030] By adopting this implementation, the average value is used to determine whether the light detection element is blocked by water stains, which is conducive to reducing the false judgment rate.

[0031] In combination with the first aspect, in an optional implementation of the embodiment of the present application, before starting the drying process, the method further includes:

[0032] Determining whether there is a parameter value within the target parameter range among the plurality of first diffuse reflection parameter values ​​corresponding to each of the light detection elements;

[0033] If so, the drying process is started, otherwise the process of controlling the treatment drum to rotate or ending the water stain detection is performed.

[0034] With this implementation, when no average value is within the target parameter range, the situation where multiple first diffuse reflection parameter values ​​are within the target parameter range is further used to determine whether any light detection element is blocked by water stains, thereby improving the detection accuracy of whether the light detection element is blocked.

[0035] In combination with the first aspect, in an optional implementation of the embodiment of the present application, there are multiple target locations, or,

[0036] The lifting rib is arranged in the treatment drum, and there are a plurality of target positions, which are distributed along the circumference of the treatment drum, and at least one target position makes the lifting rib not contact the clothes in the treatment drum;

[0037] The generating a detection result indicating the presence or absence of water stains according to a matching condition between the first diffuse reflection parameter value and a preset target parameter interval includes:

[0038] If the first diffuse reflection parameter value corresponding to any one of the plurality of target positions is within the target parameter interval, a detection result indicating the presence of water stains is generated.

[0039] According to a second aspect of an embodiment of the present application, a method for identifying clothing material is provided, which is applied to a clothing processing device, wherein the clothing processing device includes a processing drum, wherein a lifting rib is provided in the processing drum, wherein a receiving groove is provided on the lifting rib, wherein a light detecting element for detecting clothing is provided in the receiving groove, wherein a light transmitting portion covering the receiving groove is provided on the lifting rib, and wherein a light signal emitted by the light detecting element can pass through the light transmitting portion to illuminate clothing, wherein the method includes:

[0040] The water stains on the light-transmitting portion are detected by using the above-mentioned lifting rib water stain detection method;

[0041] If the detection result is that there is no water stain, controlling at least one of the light detection elements to detect the material of the clothing based on diffuse reflection of the light signal to identify the material type of the clothing;

[0042] Different material types correspond to different material parameter ranges, and the target parameter range is different from the material parameter range.

[0043] By adopting this implementation mode, the lifting rib water stain detection method can be used to identify whether the light detection element is blocked by water stains, and then the clothing material is identified when there are no water stains, thereby improving the accuracy of clothing material identification.

[0044] In combination with the first aspect, in an optional implementation of the embodiment of the present application, before detecting the water stain on the light-transmitting portion, the method further includes:

[0045] Acquiring humidity parameters in the processing cylinder;

[0046] If the humidity parameter exceeds a preset humidity threshold, the drying process is started, otherwise the water stain detection on the light-transmitting portion is performed.

[0047] By adopting this implementation method, the humidity in the processing drum is also detected, so that the humidity in the processing drum is not easy to be too high, so that water stains are not easy to precipitate and block the light detection element, thereby improving the accuracy of clothing material recognition.

[0048] In combination with the first aspect, in an optional implementation of the embodiment of the present application, controlling at least one of the light detection elements to detect the material of the clothing based on diffuse reflection of the light signal to identify the material type of the clothing includes:

[0049] Controlling at least one of the light detection elements to detect clothing based on diffuse reflection of the light signal to obtain a second diffuse reflection parameter value;

[0050] The material type corresponding to the material parameter interval in which the second diffuse reflection parameter value is located is determined as the material type of the clothing.

[0051] By adopting this implementation method, the material type of clothing is detected using diffusely reflected light signals, which is beneficial to improving the reliability of clothing material recognition.

[0052] According to a third aspect of an embodiment of the present application, a control method for a clothing processing device is provided, comprising the above-mentioned lifting rib water stain detection method or the above-mentioned clothing material identification method.

[0053] According to a fourth aspect of an embodiment of the present application, a clothing processing device is provided, which is applied with the above-mentioned clothing lifting rib water stain detection method or the above-mentioned clothing material identification method or the above-mentioned control method.

[0054] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, it includes a processing cylinder, wherein a plurality of lifting ribs are provided in the processing cylinder, a receiving groove is opened on the lifting ribs, a light detection element for detecting clothes is provided in the receiving groove, and a light-transmitting portion covering the receiving groove is provided on the lifting ribs, and a light signal emitted by the light detection element can pass through the light-transmitting portion and contact the clothes.

[0055] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, the multiple lifting ribs are arranged at equal intervals in the processing cylinder.

[0056] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, the plurality of lifting ribs are arranged at equal intervals in the processing cylinder; and / or,

[0057] Adjacent lifting ribs among the plurality of lifting ribs are spaced 120 degrees apart.

[0062] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0063] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0064] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0065] With the development of technology and the increase in user demand, the processing accuracy of clothing processing equipment has also improved. Taking washing machines as an example, current washing machines usually identify the material of clothes before processing them, so that clothes of different materials can use different processing parameters, which helps to improve the processing effect of clothes.

[0066] At present, material recognition mostly relies on cameras and other photographic devices, which use image algorithms to identify the material of clothing through the captured clothing images. However, in actual use, clothing not only easily blocks the camera, but also easily forms water mist or fails to automatically focus, resulting in poor clarity of the captured clothing images, which reduces the accuracy of clothing detection.

[0067] Based on this, the embodiment of the present application provides a method for detecting water stains on lifting ribs, wherein a receiving groove is provided on the lifting rib, a light detecting element for detecting clothing is provided in the receiving groove, and a light-transmitting portion covering the receiving groove is provided on the lifting rib, and a light signal emitted by the light detecting element can pass through the light-transmitting portion to illuminate clothing, Figure 1 The flowchart of the lifting rib water stain detection method shown is as follows, and the method includes the following processing procedures.

[0068] S100, controlling the light detection element in the lifting rib to detect the clothes at the target position based on the diffuse reflection of the light signal, and obtaining a first diffuse reflection parameter value of the light detection element corresponding to the target position.

[0069] There can be only one lifting rib or multiple lifting ribs. When there are multiple lifting ribs, there can also be multiple light detection elements, which can correspond to the lifting ribs one by one. It should be noted that there is no limit on the number of light detection elements in each lifting rib. When controlling the light detection element to detect clothing, each light detection element can be controlled to detect in sequence, or all light detection elements can be started at the same time for detection. This embodiment does not make specific limitations on this.

[0070] After the light detection element is activated, it will emit a light signal and receive the light signal after diffuse reflection from the clothing, and the first diffuse reflection parameter value can be generated according to the light signal after diffuse reflection. The first diffuse reflection parameter value can be a parameter such as the wavelength and frequency of the light signal, or a parameter value calculated using the wavelength, frequency and other parameters, which is not specifically limited in this embodiment.

[0071] In one 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.

[0072] 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.

[0073] In one embodiment, the preset calculation formula for calculating the diffuse reflection parameter value can be a formula including the wavelength and light intensity of the reflected light signal, for example, the diffuse reflection parameter value a = (wavelength λ-absorbed wavelength △E) / wavelength λ*φluminous flux*power factor (related to light intensity).

[0074] In one embodiment, in order to determine the material of 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.

[0075] 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.

[0076] 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.

[0077] The target position includes a position where the light detecting element is not covered by clothing.

[0078] S102: Generate a detection result indicating whether there is water stain according to a matching condition between the first diffuse reflection parameter value and a preset target parameter range.

[0079] Among them, the target parameter range is used to determine whether there is water stain on the light-transmitting part. That is to say, when the light detection element performs normal detection on clothing, the parameter range used is different from the target parameter range. When there is water stain on the light-transmitting part, the first diffuse reflection parameter value obtained will fall within the target parameter range. Therefore, the target parameter range can be obtained through experiments. For example, water stains are set on the light-transmitting part, and the light detection element is used to illuminate clothing of different materials and collect the first diffuse reflection parameter value, and the target parameter range corresponding to various materials is determined according to the first diffuse reflection parameter value.

[0080] By adopting this embodiment, the light detection element is controlled to detect and obtain a first diffuse reflection parameter value, and the first diffuse reflection parameter value is compared with the target parameter interval. It can be identified whether the light detection element is blocked by water stains based on the matching situation of the first diffuse reflection parameter value and the target parameter interval, which is beneficial for timely removal of water stains when there is water stains, thereby improving the detection accuracy of the light detection element when detecting clothes.

[0081] In a possible embodiment of the present application, there are multiple lifting ribs, and the light detection element in each lifting rib corresponds to a corresponding first diffuse reflection parameter value;

[0082] According to the matching of the first diffuse reflection parameter value and the preset target parameter range, a detection result characterizing the presence or absence of water stains is generated, including:

[0083] Determining whether a first diffuse reflection parameter value corresponding to at least one light detection element in the lifting rib is within a target parameter range;

[0084] If yes, the test result is water stain;

[0085] If not, the test result is no water stains.

[0086] In one embodiment, since the positions of the plurality of lifting ribs are uncertain, it is also uncertain whether the clothing covers the lifting ribs. The target parameter interval is set for the light detection element in the lifting ribs not covered by clothing, and when the light detection element not covered by clothing is not affected by water stains, the first diffuse reflection parameter value corresponding to the light detection element will not fall within the target parameter interval, and when the light detection element not covered by clothing is affected by water stains, the first diffuse reflection parameter value corresponding to the light detection element will fall within the target parameter interval. Based on this principle, when no first diffuse reflection parameter value falls within the target parameter interval, it can be determined that there is no water stain on the light-transmitting portion not covered by clothing.

[0087] By adopting this implementation method, if the first diffuse reflection parameter value is within the target parameter range, it proves that the light detection element not covered by clothes is blocked by water stains. Conversely, if the first diffuse reflection parameter value is not within the target parameter range, it proves that no light detection element is blocked by water stains. This judgment method is conducive to ensuring the accuracy of the detection results, and the amount of calculation is small, thereby reducing the occupation of computing resources.

[0088] Optionally, in one implementation of this embodiment, a plurality of lifting ribs are disposed in the processing cylinder;

[0089] The method also includes:

[0090] If the detection result is that there is no water stain, the number of rotations of the treatment drum for changing the target position is obtained and it is determined whether the number of rotations is less than the set number. If so, the treatment drum is controlled to rotate to change the position of the light detection element, and after the treatment drum stops rotating, the light detection elements in each lifting rib are controlled to detect the clothes based on the diffuse reflection of the light signal, and a first diffuse reflection parameter value corresponding to each light detection element is obtained;

[0091] If the detection result shows that there is water stain, the drying process will be started.

[0092] After the processing drum rotates, the position of the lifting ribs will change, causing at least one light detection element previously covered by clothes to rotate to a position not covered by clothes, thereby detecting water stains on the light-transmitting portion of the light detection element.

[0093] The drying process can deliver hot air flow into the processing cylinder, and the hot air flow can dry the water stains on the light-transmitting part. As for the temperature, air flow rate and drying time of the hot air flow in the drying process, this embodiment does not make specific restrictions.

[0094] By adopting the present implementation method, if the light detection element is not blocked by water stains, the processing drum can be rotated to change the position of the light detection element, so that the re-executed detection of the first diffuse reflection parameter value can continue to detect the blockage of other light detection elements; on the contrary, if the first diffuse reflection parameter value is within the target parameter range, it proves that the light detection element is blocked by water stains. At this time, starting the drying process can easily remove the water stains blocking the light detection element. After the water stains are removed, the subsequent use of the light detection element to identify clothes is not easily disturbed by the water stains, thereby improving the accuracy of recognition.

[0095] Optionally, in an implementation of this embodiment, after determining whether the number of rotations is less than the number of lifting ribs, the method further includes:

[0096] When the number of rotations of the processing cylinder is equal to the set number, a detection result is generated based on the first diffuse reflection parameter value corresponding to each light detection element obtained by the last detection.

[0097] With this implementation, when the number of rotations reaches the set number, it proves that there may be only one light detection element that is blocked and has not been detected. Therefore, performing the last detection is beneficial to improving the efficiency of identifying whether the light detection element is blocked, thereby improving the efficiency of subsequent use of the light detection element to identify clothing.

[0098] In one embodiment, the setting number is the same as the number of lifting ribs. The light detection elements in each lifting rib are controlled to detect the clothes based on diffuse reflection of the light signal, and the number of first diffuse reflection parameter values ​​corresponding to each light detection element is the same as the number of lifting ribs.

[0099] It should be noted that each time the light detection elements in each lifting rib are controlled to detect clothing based on diffuse reflection of light signals, after obtaining the first diffuse reflection parameter value corresponding to each light detection element, subsequent steps will be executed to generate new detection results.

[0100] With this implementation, when the number of rotations reaches the set number, it proves that there may be only one light detection element that is blocked and has not been detected. Therefore, performing the last detection is beneficial to improving the efficiency of identifying whether the light detection element is blocked, thereby improving the efficiency of subsequent use of the light detection element to identify clothing.

[0101] Optionally, in an implementation of this embodiment, controlling the processing cylinder to rotate includes:

[0102] The processing cylinder is controlled to rotate to a target angle, where the target angle is a preset value or is related to the number of lifting ribs, and the more the number of lifting ribs, the smaller the target angle.

[0103] In one embodiment, when calculating the target angle, the target angle can be obtained by using 360 / the number of lifting ribs-preset constant, wherein the preset parameter is, for example, -5 degrees or 5 degrees, which is not specifically limited in this embodiment.

[0104] With this implementation, the target angle is a preset angle, which helps to reduce the amount of calculation when controlling the rotation of the processing tube according to the target angle, thereby reducing the occupation of computing resources. When the target angle is not preset, the target angle is automatically calculated according to the number of light detection elements. When the calculated target angle is used to control the rotation of the processing tube, it is easy to ensure that at least one light detection element is not covered by clothing. At this time, the light detection element not covered by clothing can be detected, thereby ensuring that the occlusion of all light detection elements can be detected.

[0105] Optionally, in an implementation of this embodiment, each light detection element corresponds to a plurality of target positions and further corresponds to a plurality of first diffuse reflection parameter values;

[0106] According to the matching of the first diffuse reflection parameter value and the preset target parameter range, a detection result characterizing the presence or absence of water stains is generated, including:

[0107] Calculate the average value of a plurality of first diffuse reflection parameter values ​​corresponding to each light detection element;

[0108] If the average value corresponding to at least one optical detection element is within the target parameter range, the processing drum is controlled to rotate, otherwise the drying process is started.

[0109] By adopting this implementation, the average value is used to determine whether the light detection element is blocked by water stains, which is conducive to reducing the false judgment rate.

[0110] Optionally, in an implementation of this embodiment, before starting the drying process, the method further includes:

[0111] Determine whether there is a parameter value within a target parameter range among the multiple first diffuse reflection parameter values ​​corresponding to each light detection element;

[0112] If so, the drying process is started, otherwise the rotation of the treatment drum is controlled or the water stain detection is ended.

[0113] With this implementation, when no average value is within the target parameter range, the situation where multiple first diffuse reflection parameter values ​​are within the target parameter range is further used to determine whether any light detection element is blocked by water stains, thereby improving the detection accuracy of whether the light detection element is blocked.

[0114] Optionally, in an implementation of this embodiment, there are multiple target locations, or,

[0115] The lifting ribs are arranged in the treatment drum, and there are multiple target positions, which are distributed along the circumference of the treatment drum, and at least one target position makes the lifting ribs not contact the clothes in the treatment drum;

[0116] According to the matching of the first diffuse reflection parameter value and the preset target parameter range, a detection result characterizing the presence or absence of water stains is generated, including:

[0117] If the first diffuse reflection parameter value corresponding to any one of the multiple target positions is within the target parameter interval, a detection result indicating the presence of water stains is generated.

[0118] The embodiment of the present application also provides a method for identifying clothing materials, which is applied to a clothing processing device. The clothing processing device includes a processing drum, a lifting rib is provided in the processing drum, a receiving groove is provided on the lifting rib, a light detection element for detecting clothing is provided in the receiving groove, and a light-transmitting portion covering the receiving groove is provided on the lifting rib. The light signal emitted by the light detection element can pass through the light-transmitting portion to illuminate the clothing. Figure 2 As shown, the method includes:

[0119] S200, using the above-mentioned lifting rib water stain detection method to detect water stains on the light-transmitting part.

[0120] It should be noted that when water stains are detected, the water stains are removed, for example, a drying process is started. This embodiment does not specifically limit this, and the purpose is to ensure that there are no water stains on the light-transmitting portion.

[0121] S202: If the detection result is that there is no water stain, control at least one light detection element to detect the material of the clothing based on diffuse reflection of the light signal to identify the material type of the clothing.

[0122] Among them, different material types correspond to different material parameter ranges, and the target parameter range is different from the material parameter range.

[0123] In one embodiment, different clothing materials have different degrees of absorption or consumption of light signals, so the material type of clothing can be identified by using the light detection element to obtain an identification result.

[0124] By adopting this implementation mode, the lifting rib water stain detection method can be used to identify whether the light detection element is blocked by water stains, and then the clothing material is identified when there are no water stains, thereby improving the accuracy of clothing material identification.

[0125] Optionally, in an implementation of this embodiment, before detecting the water stains on the light-transmitting portion, the method further includes:

[0126] Obtaining humidity parameters in the processing cylinder;

[0127] If the humidity parameter exceeds the preset humidity threshold, the drying process is started, otherwise the water stains on the light-transmitting part are detected.

[0128] In other embodiments, the humidity determination process may also be performed after the water stain on the light-transmitting portion is detected. Specifically, when the detection result is that there is no water stain, the humidity determination process is performed.

[0129] By adopting this implementation method, the humidity in the processing drum is also detected, so that the humidity in the processing drum is not easy to be too high, so that water stains are not easy to precipitate and block the light detection element, thereby improving the accuracy of clothing material recognition.

[0130] Optionally, in an implementation of this embodiment, controlling at least one light detection element to detect the material of clothing based on diffuse reflection of a light signal to identify the material type of the clothing includes:

[0131] Controlling at least one light detection element to detect clothing based on diffuse reflection of the light signal to obtain a second diffuse reflection parameter value;

[0132] The material type corresponding to the material parameter interval in which the second diffuse reflection parameter value is located is determined as the material type of the clothing.

[0133] In one embodiment, different material types correspond to different material parameter ranges. When the light detection element detects the material of clothing, the second diffuse reflection parameter value will also change with the different material types of the detected clothing, so that when the second diffuse reflection parameter value falls within a certain material parameter range, the material type corresponding to the material parameter range can be determined as the material type of the clothing.

[0134] By adopting this implementation method, the material type of clothing is detected using diffusely reflected light signals, which is beneficial to improving the reliability of clothing material recognition.

[0135] An embodiment of the present application also provides a method for controlling a clothing processing device, including the above-mentioned lifting rib water stain detection method or the above-mentioned clothing material identification method.

[0136] An embodiment of the present application also provides a clothing processing device, which is applied with the above-mentioned clothing lifting rib water stain detection method or the above-mentioned clothing material identification method or the above-mentioned control method.

[0137] Optionally, in an implementation of the present embodiment, the clothing processing device includes a processing drum, a plurality of lifting ribs are provided in the processing drum, a receiving groove is opened on the lifting ribs, a light detection element for detecting clothing is provided in the receiving groove, a light-transmitting portion for covering the receiving groove is provided on the lifting ribs, and a light signal emitted by the light detection element can pass through the light-transmitting portion and contact the clothing.

[0138] Optionally, in an implementation of this embodiment, a plurality of lifting ribs are arranged at equal intervals in the processing cylinder.

[0139] Optionally, in an implementation of this embodiment, a plurality of lifting ribs are arranged at equal intervals in the processing cylinder; and / or,

[0140] Adjacent lifting ribs among the plurality of lifting ribs are spaced 120 degrees apart.

[0141] Optionally, in an implementation of this embodiment, the clothing processing device includes at least one of a drum washing machine and a washer-dryer.

[0142] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0143] In a specific implementation of the embodiment of the present application, Figure 3 As shown, the clothing material recognition method includes the following processing steps:

[0144] The three lifting ribs in the drum are all equipped with light sensors (ultraviolet sensors or near-infrared sensors). When the washing machine door is closed, the humidity sensor in the drum starts to detect the humidity in the drum. First, is the humidity RH in the drum less than 40%? If so, the transparent protective shell that protects the light sensor will be tested for water stains. The main board controls the drum to rotate 100°. The reason for rotating 100° is: there are 3 lifting ribs in the drum. If it rotates 90°, only 1 lifting rib can be guaranteed to be above the inner drum. When there are more clothes, 2 lifting ribs are blocked by clothes, but rotating 100° can avoid this problem. At least 1-2 lifting ribs can be guaranteed not to be blocked by clothes. Specifically, the rotation angle can be selected between 90-120 degrees.

[0145] After rotating 100°, the lifting rib is not blocked by clothes and is above the inner drum. At this time, the light sensor inside the lifting rib is started, and sampling is performed on the three lifting ribs. Because the lifting ribs are only controlled by angle, it is uncertain which specific lifting rib is not blocked by clothes. Therefore, the light sensors inside the three lifting ribs start working, and after emitting the corresponding light waves through diffuse reflection of the emitter and the receiver, data is collected continuously for 5 times, once every 1s. The average parameters corresponding to the collection parameters of each lifting rib sensor are a, b, and c.

[0146] Compare the various collected parameters to determine whether at least one of a, b, and c is within the range of 391-400 (target parameter range)? If so, rotate 100° again, rotate the remaining lifting ribs blocked by clothes to a state where they are not blocked by clothes, and detect the parameters again according to the above method. If the average parameter detected is not within the range of 391-400, determine the specific collected parameters. If the collected parameters are 300, 320, 391, 340, and 380, respectively, and only two parameters are close to and fall within the range of 391-400, it proves that there are water stains on the transparent protective shell at this time, and the water stains on the transparent shell are refracted during diffuse reflection, which weakens the intensity of the light waves received by the receiving electrode that is diffusely reflected. After determining that there are water stains on the transparent shell of the lifting rib, the mainboard controls the drying system of the washing machine to start working, the electric heating and the fan start to work, and the drum starts to rotate at 100r / min and continues to work for 30s to ensure that the water on the transparent shell of the lifting rib is dried and dried. After 30 seconds, collect parameters again. If the parameters collected again are stable at 391-400, the transparent shell is now dry and water stains or water droplets formed by moisture have been removed. Perform two more tests to ensure that the protective shells on the three lifting ribs are dry.

[0147] After the humidity in the drum is maintained at 30%-40% RH and there is no water stain on the protective shell on each lifting rib, the material of the clothes in the drum is detected. Based on the material parameters of the clothes in the drum, the corresponding clothing material is detected, and then the appropriate washing mode is adjusted to start washing.
