[0002] Clothes processing equipment is an indispensable device in daily life. It can perform such processing as washing, dehydrating, drying, and caring for clothes, greatly improving the convenience of clothing processing. With the development of technology and the increase in user needs, the processing accuracy of clothes by 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 as to use different operating parameters for different materials and improve the processing effect of clothes.

[0003] However, current material recognition methods mostly rely on photography technology, and require constantly turning over clothes or adjusting the shooting angle to ensure the accuracy of material recognition. However, this method reduces the efficiency of material recognition. Summary of the invention

[0004] The embodiments of the present application provide a clothing material identification method, a device control method and a clothing processing device, so as to at least solve the technical problem of low clothing material identification efficiency.

Through this means, the target light detection element can be used to quickly detect the material of the clothing, thereby improving the efficiency of clothing material recognition. At the same time, since the material type detected by the target light detection element corresponds to the clothing, the recognition accuracy of the clothing material is improved.

[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] The present application provides a method for identifying clothing materials, which is applied to a clothing processing device. The clothing processing device includes a processing drum, and a plurality of light detection elements are arranged in the processing drum. Different light detection elements are used to detect different material types. Figure 1 The flowchart of the clothing material identification method shown in FIG. 1 includes the following processing steps.

[0066] S100, estimating the material loaded in the processing cylinder to obtain a predicted material type.

[0067] This embodiment does not specifically limit the estimation method. The user can input the predicted material type to complete the estimation process, or the estimation can be performed using parameters such as load weight, water absorption, water absorption speed or density.

[0068] For ease of understanding, the material types of clothing may include cotton, linen, wool, polyester, chemical fiber, and silk. Since there may be multiple pieces of clothing in the treatment drum, the predicted material types may also include multiple types. For example, the predicted material types include cotton and wool, which proves that the estimated result is that there are cotton clothing and wool clothing in the treatment drum.

[0069] S102, controlling the light detection element at the target position to collect the light signal diffusely reflected by the load to obtain a diffuse reflection parameter value.

[0070] The optical detection component can emit a light signal. After the light signal contacts the load, diffuse reflection occurs. The optical detection component collects the diffusely reflected light signal to obtain a diffuse reflection parameter value. It should be noted that the diffuse reflection parameter value can be the light intensity and / or wavelength of the light signal, or it can be a value obtained by calculating the light intensity and / or wavelength. This embodiment does not limit the specific algorithm of the diffuse reflection parameter value, as long as the diffuse reflection parameter values ​​corresponding to different material types can be located in different intervals through calculation. For example, after weighted calculation, the diffuse reflection parameter value corresponding to cotton belongs to interval A1, linen belongs to interval A2, and so on.

[0071] S104: Determine the position of a target light detection component for material detection on the load according to the difference between the diffuse reflection parameter value and the diffuse reflection parameter interval corresponding to the predicted material type.

[0072] Since different material types correspond to different diffuse reflection parameter intervals, the obtained diffuse reflection parameter value will be within a diffuse reflection parameter interval. By comparing the diffuse reflection parameter interval of the diffuse reflection parameter value with the diffuse reflection parameter interval corresponding to the predicted material type, the difference can be obtained. On the one hand, the difference can determine whether the diffuse reflection parameter interval in which the diffuse reflection parameter value is located is the same as the diffuse reflection parameter interval corresponding to the predicted material type. On the other hand, the diffuse reflection parameter value can also be used to determine which type of material the light detection device at the target position is used to collect.

[0073] S106, controlling the processing tube so that the target light detection element is at the target position to perform material detection on the load to obtain the actual material type of the load.

[0074] In one embodiment, controlling the processing cylinder includes controlling the processing cylinder to rotate or not rotate, so as to be able to rotate the target light detection member to a target position. Preferably, the target position is the bottom position of the processing cylinder.

[0075] Through the above content, the material of the load is first estimated, and then the position of the target light detection element used to detect the material of the clothing is determined through the diffuse reflection parameter value collected by the light detection element at the target position, and finally the processing cylinder is controlled to rotate the target light detection element to the target position to detect the material of the load. Through this means, the target light detection element can be used to quickly detect the material of the clothing, thereby improving the efficiency of clothing material recognition. At the same time, since the material type detected by the target light detection element corresponds to the clothing, the recognition accuracy of the clothing material is improved.

[0076] In a possible embodiment of the present application, determining the position of a target light detection component for material detection of a load according to a difference between a diffuse reflection parameter value and a diffuse reflection parameter interval corresponding to a predicted material type includes:

[0077] If the diffuse reflection parameter value is within the diffuse reflection parameter interval corresponding to the predicted material type, then there is no difference in the representation, and it is determined that the target light detection component is at the target position;

[0078] If the diffuse reflection parameter value is not within the diffuse reflection parameter interval corresponding to the predicted material type, it indicates that there is a difference, and the position of the target light detection component is determined according to the preset position relationship between the light detection component currently at the target position and other light detection components.

[0079] Among them, the difference situations include no difference and difference. When there is no difference, it is proved that the diffuse reflection parameter interval where the diffuse reflection parameter value is located is the same as the diffuse reflection parameter interval corresponding to the predicted material type, that is, the light detection element at the target position is the target light detection element; when there is a difference, it is necessary to determine the position of the target light detection element.

[0080] As stated in the foregoing, the type of material that the light detection element at the target position is used to detect can be known through the diffuse reflection parameter value collected by it, so the position of the target light detection element can be determined in combination with the preset position relationship.

[0081] For example, there are three light detectors A, B, and C. A is used to detect cotton, B is used to detect linen, and C is used to detect wool. B is located between A and C, and the three light detectors are 120 degrees apart. When the light detector at the target position is A, if the predicted material type is linen, the target light detector is B, and the position of B can be determined.

[0082] Through the above content, since the positions of multiple light detection components are fixed or known in advance, after knowing which light detection component is currently at the target position, the preset position relationship between the light detection component and other light detection components can be used to determine the position of the target light detection component, thereby improving the efficiency and accuracy of determining the position of the target light detection component.

[0083] Optionally, in an implementation of this embodiment, a plurality of light detecting elements have a preset position relationship, and different light detecting elements are used to detect different material types, and different material types correspond to different diffuse reflection parameter intervals;

[0084] Determining the position of the target light detection component according to the preset position relationship between the light detection component currently at the target position and other light detection components includes:

[0085] The angle value between the target light detection component used to detect the predicted material type and the light detection component currently at the target position is determined from the preset position relationship to obtain the position of the target light detection component.

[0086] According to the above content, by determining the angle value, the processing drum can be controlled to rotate according to the angle value, and the target light detection element can be rotated to the target position, which helps to improve the recognition efficiency of the clothing material.

[0087] Optionally, in an implementation of this embodiment, controlling the processing cylinder includes:

[0088] If the target light detecting element is at the target position, the processing cylinder is controlled to remain stationary;

[0089] If the target light detecting element is not at the target position, the processing cylinder is controlled to rotate according to the angle value.

[0090] Through the above content, the logic is simple, easy to control, and the occupation of computing resources is reduced.

[0091] In one embodiment, if it is impossible to determine which light detection element is at the target position based on the collected diffuse reflection parameter value, the deviation value between the diffuse reflection parameter interval corresponding to the diffuse reflection parameter value and the diffuse reflection parameter interval corresponding to the predicted material type can be calculated, thereby determining the distance between the target light detection element and the target position based on the deviation value.

[0092] Optionally, in an implementation of this embodiment, estimating the material loaded in the processing cylinder to obtain a predicted material type includes:

[0093] Obtaining the load volume and load mass in the processing cylinder;

[0094] The mixed load density of the load is obtained based on the load volume and load mass;

[0095] The predicted material type is determined based on the mixed load density and the preset density ratio formula.

[0096] In one embodiment, the load volume and load mass may be obtained by calculation or by other means, such as user input or acquisition by other sensors.

[0097] Substituting the load volume and load mass into the density formula, the mixed load density can be obtained.It should be noted that the mixed load density is not necessarily the load density of mixed clothes;

[0098] Through the above content, using the density of the load, that is, the mixed load density to estimate the material type of the load is beneficial to improve the accuracy of predicting the material type.

[0099] Optionally, in an implementation of this embodiment, determining the predicted material type according to the mixed load density and a preset density ratio formula includes:

[0100] Substituting the mixed load density into the density ratio formula, at least one predicted material type is obtained;

[0101] Among them, the density ratio formula is ρ=k1*ρ1±k2*ρ2±k3*ρ3±……±kn*ρn;

[0102] Where ρ is the mixed load density, ρ1 to ρn are the densities of loads of different material types, k1 to kn are proportional constants and are integers, and n is a positive integer;

[0103] Among them, ρ1 to ρn are known quantities. After substituting ρ, at least one of k1 to kn is randomly assigned a value until both sides of the equation are equal. The material type corresponding to the one that meets the conditions among ρ1 to ρn is taken as the predicted material type. The condition is that the proportional constant is not 0 and not a negative integer.

[0104] For example, if the calculated density is 100g / cm3, the corresponding preset density of the cotton is 45g / cm 3 , the corresponding density of silk is 15g / cm 3 , the corresponding density of wool is 40g / cm 3 According to the current formula, the calculated value should be one piece of cotton, one piece of silk, and one piece of wool, so we can determine k1=1, k3=1, and k5=1.

[0105] Through the above content, the calculation process is simple, which is conducive to saving computing resources and improving the accuracy of predicting material types.

[0106] Optionally, in an implementation of this embodiment, a lighting element is provided in the clothes processing device;

[0107] Obtain the load volume in the treatment cylinder, including:

[0108] Acquire a first light intensity of reflected light from the illumination element when the treatment tube is empty;

[0109] Obtaining the empty cylinder volume according to the corresponding relationship between the first light intensity and the preset light intensity volume;

[0110] acquiring a second light intensity of the reflected light of the illumination element after the load is placed in the processing tube;

[0111] The load volume is obtained according to the light intensity difference between the first light intensity and the second light intensity, the first light intensity and the empty cylinder volume.

[0112] In one embodiment, the light intensity will be different depending on the space occupied by the clothes. The light intensity-volume correspondence can be obtained based on the linear relationship between the light intensity and the volume. Therefore, when the first light intensity is obtained, the empty barrel volume can be obtained from the light intensity-volume correspondence.

[0113] Specifically, the load volume V1=Δλ / λ*V, wherein Δλ is the light intensity difference between the first light intensity and the second light intensity, λ is the first light intensity, and V is the empty barrel volume.

[0114] Through the above content, using light intensity to calculate the load volume is conducive to improving the accuracy of the load volume, thereby improving the accuracy of predicting material type.

[0115] Optionally, in an implementation of this embodiment, obtaining the load volume according to the light intensity difference between the first light intensity and the second light intensity, the first light intensity, and the empty cylinder volume includes:

[0116] The light intensity difference is compared with the first light intensity and then multiplied by the empty tube volume to obtain the load volume.

[0117] Through the above content, the calculation process is simple and helps to save computing resources.

[0118] Optionally, in an implementation of this embodiment, the method further includes:

[0119] The load mass is obtained according to the current change of the driver before and after the processing cylinder is placed in the load, wherein the driver is used to drive the processing cylinder to rotate.

[0120] Optionally, in an implementation of this embodiment, the method further includes: determining a light detection component capable of detecting the predicted material type as the target light detection component;

[0121] The controlling the processing cylinder so that the target light detection element is at the target position to perform material detection on the load includes:

[0122] When there are multiple target light detection components, the processing cylinder is controlled so that the multiple target light detection components are located at the target positions one by one and perform material detection on the load.

[0123] In one embodiment, the predicted material type may include multiple types of materials, such as cotton and linen. In this case, two target light detection elements are determined, one for cotton detection and the other for linen detection. In this case, the processing drum is controlled to rotate so that each target light detection element is at the target position one by one to detect the clothes.

[0124] Through the above content, multiple target light detection elements are located at the target position one by one for detection, which is conducive to enabling multiple target light detection elements to detect clothes of different materials respectively, thereby improving the comprehensiveness of material detection and the detection accuracy of each material.

[0125] Optionally, in an implementation of this embodiment, when there are multiple target light detection components, controlling the processing cylinder so that the multiple target light detection components are located at the target position one by one includes:

[0126] If the light detecting element currently at the target position is one of the plurality of target light detecting elements, the rotation angles of the processing tube are determined according to the positional relationship between the target light detecting element currently at the target position and the other target light detecting elements, so that the plurality of target light detecting elements are at the target position one by one;

[0127] If the light detection component currently at the target position does not belong to one of the multiple target light detection components, the rotation angles of the processing tube are determined successively according to the positional relationship between the light detection component currently at the target position and the multiple target light detection components, so that the multiple target light detection components are at the target position one by one.

[0128] In one embodiment, it is necessary to first determine whether the light detection component at the target position belongs to one of multiple target light detection components. The specific detection method can be based on the difference between the diffuse reflection parameter value of the light detection component at the target position and the diffuse reflection parameter interval corresponding to the predicted material type, which will not be repeated. If the light detection component at the target position is one of multiple target light detection components, the rotation angle of the processing tube can be determined directly according to the positional relationship between the target light detection components. If the light detection component at the target position is not the target light detection component, first determine which material the light detection component is used to detect based on the diffuse reflection parameter interval in which the diffuse reflection parameter value of the light detection component is located. After knowing this, it can be clear which light detection component the light detection component is, thereby knowing its positional relationship with the target light detection component.

[0129] The positional relationship includes an angle, and the processing cylinder can be controlled to rotate according to the angle.

[0130] Through the above content, the rotation angle of the processing tube is controlled by whether the light detection element at the target position belongs to the target light detection element, which is beneficial to improve the efficiency of controlling each target light detection element to be at the target position.

[0131] An embodiment of the present application also provides a control method for a clothing processing device. After the actual material type of the clothing is obtained using the above-mentioned clothing material identification method, the operating mode and / or operating parameters are adjusted according to the actual material type to process the load.

[0132] An embodiment of the present application also provides a clothing processing device, which adopts the above-mentioned clothing material identification method or the above-mentioned control method.

[0133] Optionally, in an implementation of this embodiment, an incandescent lamp serving as a lighting element is installed on the observation window of the clothing processing device, and a plurality of light detection components are installed in the processing drum of the clothing processing device.

[0134] Optionally, in an implementation of this embodiment, a plurality of lifting ribs are provided in the processing tube, and a plurality of light detecting components are installed in different lifting ribs.

[0135] 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.

[0136] In a specific implementation of the embodiment of the present application, Figure 2 As shown, the control method of the clothes processing device includes the following processing steps:

[0137] Device Description: An incandescent lamp is installed on the observation window to emit incandescent light. The inner tube is made of stainless steel.

[0140] The observation window inside the washing machine is equipped with a wireless light source near the drum side. This proposal uses an incandescent lamp, but it is not limited to an incandescent lamp. The wireless light source is also equipped with a light intensity detection sensor next to one side. At the beginning, the whole machine detects the light intensity of the inner drum in the empty state when it is reflected by the incandescent lamp. The light intensity of the inner drum reflected by the incandescent lamp is detected by the light intensity detection sensor on the observation window as light intensity λ, which corresponds to the empty drum volume V of the inner drum. At this time, the user puts the clothes into the drum, and the clothes are weighed after being put into the drum. The drive motor starts to detect the current I in the drum, and calculates the difference with the current I1 when the drum is empty to obtain △I. The mass m can be obtained by calculating the current difference △I. After the mass of the clothes in the drum is obtained, the volume of the clothes in the drum is detected by the incandescent lamp in the drum through the degree of metal reflection of the inner drum. The incandescent lamp motherboard starts to supply power and calculate the reflected light intensity λ1. The reflected light intensity λ1 is used to calculate the difference with the reflected light intensity λ in the empty barrel state, and △λ=λ-λ1 is calculated. The light intensity difference of △λ is the part of the clothes in the barrel that is blocked and not reflected. By calculating the ratio of the light intensity difference △λ to the light intensity λ of the empty barrel, and then using the relationship between the ratio and the empty barrel volume V, the volume V1 of the clothes in the barrel is calculated, V1=△λ / λ*V. After the mass and volume of the clothes in the barrel are obtained, the density ρ of the clothes in the barrel is obtained by the ratio of the mass m of the clothes in the barrel and the volume V1 of the clothes in the barrel.

[0141] The density ρ of the clothes in the drum is obtained, and then the relationship between the preset density of each material is used to calculate the proportion of each material in the mixed clothes, ρ=a*ρ1±b*ρ2±c*ρ3±d*ρ4±e*ρ5±f*ρ6. After obtaining the corresponding proportional constants a-f, the type and proportion of each material can be obtained. In this way, the proportion and material type of the mixed clothes in the drum can be preliminarily estimated. After obtaining the preliminary material type of the clothes in the drum, the ultraviolet sensor inside the lifting rib begins to detect the clothes through diffuse reflection to obtain the material parameter a. The material parameter a of the clothes in the drum is obtained to determine whether the ultraviolet sensor has been covered by the clothes in the drum. a is compared with the preset value of each material. If it is within the range of each material, there is no need to adjust the angle of the drive motor, and the material of the clothes in the drum can be directly detected. If the parameter detected by the material parameter a does not fall within the range of the preset value, several materials estimated according to the density are compared with the detected material parameter a to calculate the deviation from the preset range, and the distance between the sensor and the clothes in the drum can be calculated. After obtaining the preliminary position of the ultraviolet sensor at this time, it is directly rotated by a certain angle α to the optimal angle. After the angle adjustment is completed, the ultraviolet sensor begins to detect the material of the clothes in the drum.

[0142] After the corresponding material is obtained, the washing mode of the clothes in the drum is adjusted according to the detected material type of the clothes, and the washing mode can be started.
