DETAILED DESCRIPTION

[0048] 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.

[0050] 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.

[0051] Clothes processing equipment is an indispensable device in daily life. It can perform such treatments 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 that clothes of different materials can use different processing parameters, which helps to improve the processing effect of clothes.

[0052] Material recognition methods include video recognition, which uses a camera to take a picture of the clothing and then uses an image algorithm to analyze the material of the clothing from the clothing image.

[0053] However, in actual use, it is found that camera recognition is often affected by factors such as ambient brightness and water mist, resulting in poor clarity of the captured clothing images and reduced accuracy in identifying clothing materials.

[0054] Based on this, an embodiment of the present application provides a method for detecting the material of clothes, which detects the material of clothes in a clothes processing drum of a clothes processing device. Figure 1 The flowchart of the clothing material detection method shown is as follows. The method includes the following processing steps.

[0055] S100: When the inside of the laundry treatment drum is at a target light intensity, a parameter value characterizing the material of the laundry is obtained. The parameter value is determined based on a light signal collected by a light signal detection component, and the light signal detection component is located inside the laundry treatment drum and is used to collect a light signal after the laundry diffusely reflects the incident light signal. Exemplarily, the parameter value is the light intensity or wavelength of the collected light signal itself, or the parameter value is used to reflect the light intensity or wavelength of the collected light signal.

[0056] When identifying the material of clothing, the optical signal detection component emits an incident light signal to the clothing, and the incident light signal is diffusely reflected after contacting the clothing. In this embodiment, the optical signal detection component is used to obtain the light signal after diffuse reflection. The optical signal detection component or a processor corresponding to the optical signal detection component can convert the collected light signal into a specific numerical value for calculation, which is hereinafter referred to as a sampling value.

[0057] Optionally, in one implementation of this embodiment, when the clothes processing drum does not rotate (i.e., the state of the clothes in the clothes processing drum remains unchanged), an incident light signal is emitted toward the clothes through the light signal detection element, and a diffuse reflection light signal is received. This is repeated multiple times to obtain multiple sampling values ​​reflecting the light intensity or wavelength of the diffuse reflection light signal. Then, the above parameter value is calculated based on the multiple sampling values. The above parameter value can be an average value or median value of the multiple sampling values.

[0058] Afterwards, the laundry treatment drum can be rotated to change the laundry state, and then the laundry treatment drum is kept stationary, and the above process is repeated. This is repeated multiple times to obtain multiple parameter values ​​to cover all the laundry materials in the laundry treatment drum as much as possible.

[0059] S102: Determine the material of the clothing according to the parameter value and the corresponding relationship between the clothing material and the standard parameter value range under the target light intensity.

[0060] The standard parameter value interval is a numerical interval composed of standard parameter values. It should be noted that the parameter value and the standard parameter value are obtained by the same type of optical signal detection element using the same algorithm. The difference is that the standard parameter value is the parameter value obtained by performing a diffuse reflection experiment on the clothing when the clothing material is known, while the parameter value is the value obtained by diffuse reflection on the clothing when the clothing material is actually identified. For ease of understanding, for example, during the test, the wavelength or light intensity of the reflected light signal after diffuse reflection is calculated using formula A to obtain the standard parameter value. After multiple tests on clothing of material a, a numerical interval P1 can be divided according to all the standard parameter values ​​obtained as the standard parameter value interval corresponding to material a.

[0061] When actually identifying the material of clothing, the wavelength or light intensity of the reflected light signal after diffuse reflection is calculated using formula A to obtain the parameter value. Since the calculation process of the standard parameter value is the same as the calculation process of the parameter value during actual detection, the material of the clothing can be determined based on the parameter value during actual detection.

[0062] Among them, there is a certain correspondence between the target light intensity, clothing material, and standard parameter value interval. That is to say, when the target light intensity is determined, each type of clothing material corresponds to a standard parameter value interval, and different types of clothing materials correspond to different standard parameter value intervals.

[0063] Exemplarily, when the optical signal detection element is an ultraviolet sensor, the corresponding relationships obtained by testing under a target light intensity include: the wavelength of the collected light signal is 100-130nm, and the corresponding material is cotton; the wavelength of the collected light signal is 135-155nm, and the corresponding material is linen; the wavelength of the collected light signal is 190-230nm, and the corresponding material is wool; the wavelength of the collected light signal is 165-189nm, and the corresponding material is silk; the wavelength of the collected light signal is 290-330nm, and the corresponding material is polyester fiber; the wavelength of the collected light signal is 335-390nm, and the corresponding material is chemical fiber.

[0064] By adopting this embodiment, on the one hand, by obtaining the parameter value characterizing the clothing material under a certain target light intensity, the interference of the lighting environment on the clothing material detection is eliminated; on the other hand, clothing material identification is performed based on the correspondence between the parameter value and the target light intensity-clothing material-standard parameter value range, which is beneficial to improving the accuracy of clothing material identification.

[0065] Optionally, in an implementation of this embodiment, multiple parameter values ​​are determined in S100, and the standard value interval to which each parameter value belongs is determined in S102, thereby determining the clothing material corresponding to each parameter value. Finally, the clothing material corresponding to each parameter value is combined to obtain all clothing materials in the clothing treatment drum.

[0066] Optionally, in an implementation of this embodiment, as Figure 2 As shown, before S100, the following processing is also performed.

[0067] S200: Detecting the initial light intensity inside the laundry treatment tub.

[0068] The initial light intensity can be represented by an initial voltage value. Specifically, a first visible light sensor located inside the laundry treatment drum can be used to detect a voltage value reflecting the light intensity inside the laundry treatment drum, including an initial voltage value reflecting the initial light intensity here and a target voltage value reflecting the subsequent target light intensity.

[0069] Exemplarily, the wavelength range corresponding to the first visible light sensor is 250-290 nm. The first visible light sensor is an ultraviolet sensor.

[0070] S202: When the initial light intensity does not correspond to the target light intensity, adjusting the light intensity inside the laundry processing drum to the target light intensity.

[0071] Among them, the target light intensity is the light intensity that is smaller than the initial light intensity and closest to the initial light intensity among multiple preset light intensities. Under each of the preset light intensities, the same clothing material corresponds to a different standard reference value range.

[0072] By adopting this implementation method, when the initial light intensity does not correspond to the target light intensity, the initial light intensity can be adjusted to the target light intensity, thereby obtaining parameter values ​​and detecting / identifying clothing materials in an environment with a certain light intensity.

[0073] Optionally, in order to implement the process of S202, the clothing processing device has a glass window that can be atomized (e.g., an electro-atomized glass window), that is, the glass window of the clothing processing device adopts electro-atomized glass. By adjusting the atomization degree of the glass window that can be atomized, the light intensity in the clothing processing drum reaches the target light intensity.

[0074] In this implementation, illustratively, a first visible light sensor inside the laundry treatment drum is used to detect the light intensity β inside the drum. The first visible light sensor detects a voltage range of 0-5V, and the detected light intensity corresponds to the feedback voltage, that is, the stronger the received light intensity, the closer the voltage corresponding to the visible light sensor is to 5V.

[0075] The observation window (or glass window) of the clothing treatment equipment has an electro-atomization function, and the blurriness of the observation window can be adjusted by electro-atomization. The adjustment gear of the light intensity in the drum can be divided into 5 gears through electro-atomization, namely β1, β2, β3, β4, and β5. The corresponding gear detection voltages are U1-U5, corresponding to 1V, 2V, 3V, 4V, and 5V respectively. β1 and β2 are slightly blurred, β3 and β4 are moderately blurred, and β5 is completely blurred.

[0076] The initial light intensity in the drum needs to be detected by the first visible light sensor. Then, it is determined whether the voltage U corresponding to the detected β value is in one of the ranges β1-β5. If the corresponding voltage U falls in one of the ranges U1-U5, the light signal detection element (e.g., ultraviolet sensor) inside the lifting rib can be used to detect the material of the clothes in the drum at this level.

[0077] If the detected initial light intensity β in the drum is not in the preset gear, first convert the light intensity β to the preset gear closest to the current voltage U in U1-U5. For example, calculate the difference between the detected U and U1, U2, U3, U4, and U5, and the case with the smallest difference is the closest light intensity gear. For example, the difference between U-U1 and the other four gears is the smallest and U>U1, which is the gear closest to β1, and then adjust the electro-atomization gear to β1. Then, use the optical signal detection component (for example, ultraviolet sensor) inside the lifting rib to detect the material of the clothes in the drum at the β1 gear.

[0078] Figure 3 is a flow chart of a method for detecting clothing material according to an embodiment of the present application, referring to Figure 3 , the method includes the following processing steps.

[0079] S300: Detecting the initial light intensity inside the laundry treatment tub.

[0080] S302: Determine whether the initial illumination intensity is the target illumination intensity. If the initial illumination intensity is the target illumination intensity, execute S306; otherwise, execute S304.

[0081] S304: Adjust the light intensity inside the laundry processing drum to the target light intensity.

[0082] S306: Obtaining parameter values ​​characterizing the material of the clothes. The parameter values ​​are determined based on the light signal collected by the light signal detection element, the light signal detection element is located inside the clothes processing drum and is used to collect the light signal after the clothes diffusely reflect the incident light signal.

[0083] S308: Determine the material of the clothing according to the parameter value and the corresponding relationship between the clothing material and the standard parameter value range under the target light intensity.

[0084] It is determined whether the material of the clothing can be determined in S308. If the material of the clothing can be determined, the process ends. If the material of the clothing cannot be determined, S310 is executed.

[0085] S310: Determine the material of the clothing according to the parameter value and the compensation value of the parameter value, and the correspondence between the clothing material and the standard parameter value interval under the target light intensity. The compensation value is related to the difference between the initial light intensity and the target light intensity.

[0086] In this embodiment, please refer to the previous text for the description of S300-S308, which will not be repeated here.

[0087] In this embodiment, when the clothing material cannot be determined based on S308, the clothing material is further determined based on the parameter value and the compensation value of the parameter value, which provides further guarantee for accurately determining the clothing material value.

[0088] Optionally, in an implementation of this embodiment, S310 may be implemented in the following manner.

[0089] First, the compensation value of the parameter value is determined according to the difference between the initial light intensity and the target light intensity. For example, the compensation value of the parameter value is determined according to the voltage difference △U=U-U1 between the initial voltage value U representing the initial light intensity and the target voltage value U1 representing the target light intensity, and the voltage difference interval to which the voltage difference belongs. Among them, the multiple voltage difference intervals correspond to different compensation values. Exemplarily, 5 voltage difference intervals are preset (0, 0.2], (0.2, 0.4], (0.4, 0.6], (0.6, 0.8], (0.8, 1), and the compensation values ​​corresponding to the 5 voltage difference intervals are λ1, λ2, λ3, λ4, λ5, respectively.

[0090] On the basis of the scheme disclosed in this embodiment, those skilled in the art can determine the specific values ​​of λ1, λ2, λ3, λ4, and λ5 according to experiments. For example, multiple parameter values ​​corresponding to material A detected under a certain environment (e.g., light intensity) can be counted in multiple experiments, and the overall interval of parameter values ​​can be divided into a parameter value dense distribution interval and a parameter value scattered distribution interval by using a method of dividing discrete values ​​by density, and the standard parameter value interval corresponding to material A is determined according to the parameter value dense distribution interval, for example, the parameter value dense distribution interval is used as the standard parameter value interval. According to the parameter value scattered distribution interval or according to the parameter value in the parameter value scattered distribution interval, the compensation value is determined, for example, the median is selected from the parameter value in the parameter value scattered distribution interval, and the difference between the median and the maximum value of the parameter value dense distribution interval is calculated as the compensation value. Of course, this is just a simple example, which is intended to illustrate the way to obtain the compensation value through experiments, and to illustrate the feasibility of obtaining the compensation value through experiments. As for how to obtain the compensation value by experiment, and the specific value of the compensation value, those skilled in the art can flexibly design it according to the disclosure of this application.

[0091] Then, based on the parameter value and the compensation value of the parameter value, the compensated parameter value is determined. For example, assuming that ΔU falls within the interval (0.4, 0.6], the compensation value of the parameter value is determined to be λ3.

[0092] Afterwards, the material of the clothing is determined according to the compensated parameter value and the correspondence between the clothing material and the standard parameter value interval under the target light intensity. Assuming that the parameter value obtained in S306 is a, the compensated parameter value is a+λ3. Then, based on the compensated parameter value, the material of the clothing is determined again according to the correspondence between the clothing material and the standard parameter value interval under the target light intensity.

[0093] Optionally, in one implementation of the present embodiment, the optical signal detection element includes a first optical signal detection element and a second optical signal detection element with different wavelengths. By using two optical signal detection elements with different wavelengths, a wider range of clothing materials can be covered. Exemplarily, the first optical signal detection element is a second visible light sensor (e.g., an ultraviolet sensor), and the corresponding optical signal wavelength is 100-250nm, and the second optical signal detection element is a third visible light sensor (e.g., an ultraviolet sensor), and the corresponding optical signal wavelength is 290-400nm.

[0094] Further, in the case that the parameter value is detected by the first optical signal detection component, the compensation value of the parameter value is determined according to the difference between the initial light intensity and the target light intensity, including: determining the compensation value of the parameter value according to the voltage difference between an initial voltage value representing the initial light intensity and a target voltage value representing the target light intensity, and a first voltage difference interval to which the voltage difference belongs, wherein a plurality of the first voltage difference intervals respectively correspond to different compensation values.

[0095] In the case where the parameter value is detected by the second optical signal detection component, the compensation value of the parameter value is determined according to the difference between the initial light intensity and the target light intensity, including: determining the compensation value of the parameter value according to a voltage difference between an initial voltage value representing the initial light intensity and a target voltage value representing the target light intensity, and a second voltage difference interval to which the voltage difference belongs, wherein a plurality of the second voltage difference intervals respectively correspond to different compensation values.

[0096] That is to say, in this implementation, since the wavelength bands corresponding to the first optical signal detection element and the second optical signal detection element are different, the parameter values ​​detected by the two correspond to different compensation systems, that is, although the division of the voltage difference intervals of different optical signal detection elements may be the same, the compensation values ​​corresponding to the same voltage difference intervals are different due to the different wavelengths of the optical signal detection elements. More specifically, assuming that 5 voltage difference intervals (0, 0.2], (0.2, 0.4], (0.4, 0.6], (0.6, 0.8], (0.8, 1) are preset, then corresponding to the first optical signal detection element, the compensation values ​​corresponding to the 5 voltage difference intervals are λ11, λ12, λ13, λ14, λ15 respectively; corresponding to the second optical signal detection element, the compensation values ​​corresponding to the 5 voltage difference intervals are λ21, λ22, λ23, λ24, λ25 respectively. Based on the scheme disclosed in this embodiment, those skilled in the art can determine the specific compensation value based on experiments, and this application does not limit the specific compensation value.

[0097] Optionally, in an embodiment of the present application, after determining the material of the clothes, the washing parameters are adjusted according to the material of the clothes, including washing time, water intake time, motor speed, etc.

[0098] Optionally, in an embodiment of the present application, diffuse reflection may be generated after the light signal contacts the clothing, and then a diffuse reflection parameter value may be obtained.

[0099] 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.

[0100] 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).

[0101] In one embodiment, in order to determine the material of the clothing, a diffuse reflection standard value interval is preset (for example, the standard parameter value interval mentioned above), and different diffuse reflection standard value intervals correspond to different clothing materials, that is, the diffuse reflection standard value interval has a corresponding relationship with the clothing material.

[0102] 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.

[0103] The corresponding relationship 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 diffuse reflection standard value interval P1, which is the corresponding relationship. When the diffuse reflection parameter value is within P1, it can be determined that the clothing material of the clothing is a.

[0104] The embodiment of the present application further provides an electronic device, including a memory and a processor, wherein the memory stores one or more computer instructions, and the processor is used to execute the computer instructions to implement the clothing material detection method described above.

[0105] The embodiment of the present application also provides a clothes processing device, which includes a clothes processing drum that can be controlled to rotate; and an optical signal detection member disposed inside the clothes processing drum. The optical signal detection member is used to collect optical signals after the clothes diffusely reflect the incident optical signals.

[0106] Optionally, in an implementation of this embodiment, as Figure 4 As shown, at least one lifting rib 1 is provided on the laundry processing drum, a receiving groove 11 is provided in the at least one lifting rib 1 , and the optical signal detection element 2 is located in the receiving groove 11 .

[0107] The lifting rib 1 extends from the inner wall of the laundry treatment drum to the inside of the laundry treatment drum and has a certain height. The lifting rib 1 can be integrally formed with the laundry treatment drum, or can be connected to the inner wall of the laundry treatment drum by welding, screwing, etc. For ease of understanding, along the extension direction of the lifting rib 1, the surface of the lifting rib 1 close to the inner center of the laundry treatment drum is the upper end surface of the lifting rib 1, and the accommodating groove 11 is opened from the upper end surface toward the inner wall of the laundry treatment drum.

[0108] In this implementation, a receiving groove 11 is provided on the lifting rib 1 for installing the optical signal detection element 2, so that the optical signal detection element 2 is not easily entangled with the clothes in the clothes processing drum, and thus the optical signal detection element 2 is not easily affected by the movement of the clothes in the clothes processing drum. At the same time, the optical signal detection element 2 is located in the lifting rib 1, and can change the distance between it and the clothes as the position of the lifting rib 1 changes, which is conducive to improving the detection of the clothes by the optical signal detection element 2 and improving the detection quality.

[0109] Optionally, in one implementation of the present embodiment, the optical signal detection element 2 includes an emitter 21 and a receiver 22, which are arranged in a parallel and flat manner in the receiving groove 11, the emitter 21 is used to emit an incident light signal into the clothing processing drum, and the receiver 22 is used to receive a reflected light signal after the clothing in the processing drum reflects the incident light signal.

[0110] Optionally, in an implementation of this embodiment, the emitter 21 and the receiver 22 are arranged in sequence and parallel to each other along the rotation direction of the laundry treatment drum. There is a distance between the end faces of the emitter 21 and the receiver 22 and the upper end face of the lifting rib 1. The distance is, for example, 20 mm or 15 mm, which is not specifically limited in this implementation, and is intended to improve the detection accuracy of the optical signal detection element 2 by setting the distance.

[0111] In this embodiment, the optical signal detector 2 is installed in a manner of setting a certain distance, so that when the clothes cover the upper end surface of the lifting rib 1, there is still a certain distance between the clothes and the optical signal detector 2, which helps to improve the detection quality of the optical signal detector 2.

[0112] Optionally, in an implementation of this embodiment, a cover plate for sealing the receiving groove 11 is provided on the lifting rib 1, and the cover plate is made of waterproof and light-transmitting material. In this implementation, by providing the cover plate, the receiving groove 11 is sealed to prevent water in the laundry treatment drum from entering the receiving groove 11, thereby protecting the optical signal detection element 2 from being easily infiltrated or soaked by water, thereby increasing the service life of the optical signal detection element 2.
