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.

[0003] Most current washing machines are equipped with detection instruments to detect the material of clothes in the processing drum of the clothes processing device.

[0062] Background

[0063] Clothes processing equipment is an indispensable device in daily life. It can wash, dehydrate, dry, and care 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.

[0064] Most current washing machines are equipped with detection instruments to detect the material of clothes in the processing drum of the clothes processing device. However, in actual use, it is found that most detection instruments are limited by their installation positions, which makes it difficult to accurately detect the clothes in the processing drum in some cases, thereby reducing the accuracy of the detection results.

[0065] Based on this, Figure 1-Figure 2 As shown, a first aspect of an embodiment of the present invention provides a method for detecting clothing material, the method comprising:

[0066] Acquiring parameter values ​​under different detection states, the detection states including the detection position of the detection element and the state of the clothes in the clothes processing drum, the parameter values ​​being used to characterize the clothes material, the parameter values ​​being determined according to the light signals collected by the detection element, the detection element being used to collect the light signals after the clothes in the clothes processing drum diffusely reflect the incident light signals;

[0067] Identify the first clothing material according to the parameter values ​​under the different detection states;

[0068] If at least one clothing material is identified, a second clothing material identification is performed according to the parameter value after the clothing state is changed while keeping the detection position in the current detection state unchanged;

[0069] If at least one clothing material cannot be identified, the detection position is adjusted to update the parameter values ​​under the different detection states and the first clothing material identification is performed again, or the clothing state under the current detection state is adjusted and the second clothing material identification is performed based on the parameter values ​​after the clothing state is changed.

[0070] The clothing material detection method provided in the embodiment of the present application can identify the materials of various clothes in the clothing processing drum by continuously adjusting the state of the clothes or the detection position, so that targeted washing strategies can be adopted for the clothes according to the acquired clothing materials, thereby improving the washing effect of the clothes.

[0071] It should be noted that when the clothing processing device adopts the above-mentioned clothing material detection method, the above-mentioned detection member can be set on the lifting ribs of the clothing processing drum, and the detection position of the detection member can be changed by changing the position of the detection member relative to the lifting ribs.

[0072] It should also be noted that the detection component can output parameter values ​​representing the material of the clothing when it is in different detection positions, and the clothing processing equipment has preset multiple sets of parameter value range-material correspondence tables. When the detection component is in different detection positions, there is a corresponding set of parameter value range-material correspondence tables.

[0073] It should also be noted that the clothing processing device also has a shaking program. When the clothing processing device runs the shaking program, the clothes in the clothing processing drum can be shaken out, thereby changing the clothing state of the clothes in the clothing processing drum.

[0074] In some embodiments, the identifying the first clothing material according to the parameter values ​​under the different detection states includes:

[0075] Determine whether the parameter value in the first detection state and the parameter value in the second detection state are non-overlapping within the tolerance range;

[0076] If there is no non-overlapping situation, at least one clothing material cannot be identified; that is, multiple parameters overlap, which means that the multiple parameter values ​​at this time cannot distinguish clothing of multiple materials;

[0077] If there is a non-overlapping situation, determining whether at least one of the non-overlapping parameter values ​​is within a preset target interval;

[0078] If at least one of them is within the preset target interval, at least one clothing material can be identified;

[0079] If at least one of them does not exist within the preset target interval, at least one clothing material cannot be identified and further testing is required.

[0080] In some embodiments, the identifying the second clothing material according to the parameter value after the clothing state is changed includes:

[0081] Get the parameter value after changing the clothing state;

[0082] Determine whether the parameter value after changing the clothing state is within a preset target range;

[0083] If it is within the preset target range, the material of the clothing is determined;

[0084] If it is not within the preset target interval, the clothing state is changed and the parameter value after the clothing state is changed is re-acquired.

[0085] In some embodiments, adjusting the detection position to update the parameter value under the different detection states and re-identifying the first clothing material includes: adjusting the detection position to update the parameter value under the different detection states and re-identifying the first clothing material when there is still adjustment space at the detection position; and / or,

[0086] The adjusting of the state of the clothes in the current detection state and performing the second clothing material identification according to the parameter value after the clothing state is changed includes: when there is no adjustment space at the detection position, adjusting the state of the clothes in the current detection state and performing the second clothing material identification according to the parameter value after the clothing state is changed. That is, when the position of the detection element is adjusted for many times, but the material of the clothes is still not determined, it means that the clothes are not fully separated at this time. At this time, the clothes can be fully separated by running the shaking program, and then the parameter value representing the material of the clothes can be obtained again, and it is judged whether the parameter value is within the preset range, so as to achieve the determination of the material of the clothes.

[0087] That is, in the embodiment of the present application, by continuously adjusting the detection distance and / or the state of the clothes, the various materials of the clothes in the drum are fully tested after multiple tests, and finally the corresponding appropriate washing mode and care mode are adjusted.

[0088] In some embodiments, adjusting the detection position to update the parameter value under the different detection states includes:

[0089] If it is the first time to adjust the detection position, then the parameter value after adjusting the detection position is added to the parameter value under the different detection states before updating to obtain the updated parameter value under the different detection states.

[0090] If it is not the first time to adjust the detection position, the parameter value after adjusting the detection position is used to replace the parameter value after the previous adjustment of the detection position.

[0091] Specifically, Figure 1 and Figure 2As shown, in some embodiments, obtaining parameter values ​​under different detection states includes:

[0092] Obtaining a parameter value in a third detection state and a parameter value in a fourth detection state;

[0093] The third detection state and the fourth detection state include:

[0094] First situation: the detection position of the fourth detection state is the same as that of the third detection state, but the clothing state is different, or,

[0095] Second situation: the detection positions of the fourth detection state and the third detection state are different.

[0096] Further, in some embodiments, in chronological order, the fourth detection state is after the third detection state;

[0097] In the first situation, if at least one clothing material cannot be identified, adjusting the detection position to update the parameter value under the different detection states and re-identifying the first clothing material includes:

[0098] adjusting the detection position in the fourth detection state to obtain a fifth detection state;

[0099] The parameter value under the fifth detection state is obtained, and the parameter values ​​under the third detection state, the fourth detection state and the fifth detection state are used as the parameter values ​​under the different detection states to perform the first clothing material identification.

[0100] Furthermore, in some embodiments, when at least one clothing material cannot be identified according to the parameter values ​​in the third detection state, the fourth detection state, and the fifth detection state, adjusting the detection position to update the parameter values ​​in the different detection states and re-identifying the first clothing material includes:

[0101] adjusting the detection position in the fifth detection state to obtain a sixth detection state;

[0102] The parameter value under the sixth detection state is obtained, and the parameter values ​​under the third detection state, the fourth detection state and the sixth detection state are used as the parameter values ​​under the different detection states to perform the first clothing material identification.

[0103] Furthermore, in some embodiments, the clothing material detection method further includes:

[0104] When at least one clothing material cannot be identified based on the parameter values ​​in the third detection state, the fourth detection state, and the sixth detection state, the clothing state in the sixth detection state is adjusted and a second clothing material is identified based on the parameter value after the clothing state is changed.

[0105] In some embodiments, the fourth detection state is after the third detection state in chronological order;

[0106] In the second situation, if at least one clothing material cannot be identified, adjusting the detection position to update the parameter value under the different detection states and re-identifying the first clothing material includes:

[0107] adjusting the detection position in the fourth detection state to obtain a seventh detection state;

[0108] The parameter values ​​in the third detection state and the seventh detection state are used as updated parameter values ​​in the different detection states to identify the first clothing material.

[0109] In some embodiments, the detection member has a plurality of detection positions, the plurality of detection positions including a first detection position, a second detection position, ... an Xth detection position, where X represents a positive integer;

[0110] Among them, the target interval range values ​​corresponding to the same clothing material at different detection positions are different, that is, each detection position corresponds to a set of target interval division rules.

[0111] In the clothing material detection method provided in the embodiment of the present application, when there is overlap between the multiple parameter values ​​detected, it means that the specific clothing materials corresponding to the multiple parameters cannot be determined at this time. At this time, by adjusting the detection distance from the detection piece to the detected clothing, the detection range of the material parameters can be expanded after adjusting the detection distance, and the calculated average value can effectively avoid overlap between the parameters.

[0112] It should be noted that each parameter value obtained in the embodiment of the present application is an average parameter value, that is, the average value calculated after multiple consecutive acquisitions is used as a parameter value. Preferably, the acquisition is performed 10 times in a row, and the average value of the values ​​in a group of 10 times is calculated to obtain the average parameter value.

[0113] It should also be noted that in the embodiment of the present application, when determining whether multiple parameter values ​​overlap, it is determined whether the multiple parameter values ​​overlap within a preset tolerance range.

[0114] In some implementations, if the multiple parameter values ​​do not overlap within a preset tolerance range, the correspondence between the multiple parameter values ​​and the corresponding preset parameter value intervals is determined.

[0115] If at least one of the multiple parameter values ​​falls within the preset parameter value range, and at least one parameter value does not fall within the preset parameter value range, it means that the detection distance of the detection element is suitable for detecting the distance of a variety of mixed clothes. There is no need to adjust the distance of the detection element, just run the shaking program.

[0116] If multiple parameter values ​​do not correspond to the preset parameter value range, it means that the detection distance detected at this time is not suitable for detecting the distance of multiple mixed clothes. At this time, it is necessary to adjust the detection position of the detection device and obtain the parameter value representing the clothing material output by the detection device at the current detection position.

[0117] If multiple parameter values ​​all correspond to the preset parameter value range, it means that the materials of multiple clothes in the drum have been detected. At this time, there is no need to continue testing. You only need to select the corresponding washing strategy according to the specific clothing materials detected.

[0118] Specifically, in some embodiments, controlling the clothing processing device to execute a corresponding washing strategy according to clothing materials corresponding to a plurality of parameter values ​​includes:

[0119] The water intake amount and / or the washing drum speed and / or the washing water temperature and / or the drying temperature of the clothing processing device are controlled according to the clothing materials corresponding to the multiple parameter values.

[0120] In order to more clearly understand the working principle of the clothing processing device in the embodiment of the present application, the following is a detection element as an ultraviolet sensor and combined with Figure 1 and Figure 2 To explain in detail:

[0121] The laundry treatment drum of the laundry treatment device has a lifting rib inside, and a UV sensor is installed inside the lifting rib, and a push rod motor is installed at the bottom of the UV sensor, and different distances of the UV sensor are adjusted by the push rod motor to test different parameters. Preferably, the UV wavelength used is 100nm-400nm.

[0122] When the motor power and current are detected to indicate that there are clothes in the drum, the main board starts to send a signal to the push rod motor, first push the UV sensor to a distance of d1mm (20mm) from the top of the lifting rib, and the UV sensor emits UV rays to initially detect the material of the current clothes. The UV rays are diffusely reflected on the surface of the material. After the material absorbs part of the UV rays, the remaining UV rays that are not absorbed will be received by the sensor's receiving electrode. The received light waves are converted by the main board's algorithm to obtain parameter a. In this process, the data is collected 10 times in a row, and the average value of the values ​​in a group of 10 times is calculated to obtain the average value parameter a. Then the second detection begins. The main board first sends a signal to the drive motor of the drum to control the clothing processing equipment to run the shaking program. At this time, the push rod motor does not move, and continues to sample 10 times, and calculates the average value b. The average values ​​a and b calculated by sampling are compared to see if there is overlap in the deviation range of ±20. The parameter tolerance is the test deviation obtained by the experimental test. If a and b do not overlap within the tolerance range of ±20, then compare a and b with the preset intervals △a and △b of the mainboard program to determine whether at least one of the measured values ​​is within the preset interval. If so, it proves that the current detection distance is suitable for detecting the distance of multiple mixed clothes, and there is no need to adjust the sensor distance. If two measured values ​​can fall within the preset interval, there is no need to continue to detect mixed clothes. More than two types of clothes basically meet the types of mixed clothes washing. Then it can be determined what kind of material is in the drum, and then adjust the washing program corresponding to the mixed clothes according to the tested material to control the water intake, motor speed, washing temperature, number of rinses and drying time. If it is not within the range, directly adjust the detection distance according to the following method.

[0123] If a and b overlap within the ±20 parameter range of their respective deviations, the push rod motor under the sensor will work to push the sensor to a distance of d2 (15mm) from the top surface of the lifting rib. After adjusting the distance, sample 10 times continuously and calculate the average value b1. After obtaining the parameters, compare a and b1 or b and b1 within the ±20 tolerance range to determine whether the two intervals overlap. If there is no overlap this time, the corresponding washing mode will be run in combination with the identified mixed clothing type, and the water inlet volume, motor speed, water inlet temperature and drying temperature will be adjusted. If a, b1 or b, b1 overlap within the range of their respective tolerances of ±20, the push rod motor under the UV sensor pushes the sensor to a distance of d3 (10mm) from the top of the lifting rib. After adjusting the distance, the UV sensor performs diffuse reflection detection on the material being tested again, samples 10 times to obtain the average value c, and compares the parameters a, c or b, c obtained in the previous test to see if there is overlap within the tolerance range of ±20. If there is no overlap, a, c or b, c are compared with the preset intervals △a, △b1, △c2 to determine whether they are within their respective intervals. If so, it can be determined what materials the clothes in the final drum are made of. If a, c or b, c overlap within their respective tolerances of ±20, they are shaken again, and the push rod motor is used again to adjust the detection height of the UV sensor, and the samples are collected again 10 times to obtain the average value, and the intervals are determined again to determine whether they overlap, and so on. If the sampled average values ​​do not overlap, the materials of all the clothes in the drum can be determined.

[0124] Optionally, one or more cameras are installed around the door seal of the washing machine, or a camera is installed on the glass door of the observation window. The camera is used to take pictures of the clothes in the drum. The taken pictures are compared with the pictures in the memory of the original main board. If the same clothes can be compared, the type of clothes in the drum can be identified without using sensors to detect the material of the clothes.

[0125] The function of adjusting the detection distance from the UV sensor to the tested clothing is to expand the detection range of material parameters after adjusting the detection distance, and the calculated average value can effectively avoid overlap.

[0126] 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.

[0127] 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.

[0128] 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).

[0129] In one embodiment, in order to determine the material of the clothing, a diffuse reflection standard value interval (i.e., the preset target interval and parameter value interval mentioned above) is preset, and different diffuse reflection standard value intervals correspond to different clothing materials. In other words, there is a corresponding relationship between the diffuse reflection standard value interval and the clothing material.

[0130] 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 diffuse reflection standard values ​​obtained. 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 based on the diffuse reflection parameter value.

[0131] 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.

[0132] In this embodiment, experiments can be conducted at different detection positions to obtain the corresponding relationship between the diffuse reflection standard value range and the clothing material at different detection positions.

[0133] A second aspect of an embodiment of the present invention provides a clothing processing device, which adopts the clothing material detection method provided by the first aspect of this embodiment.

[0134] In some embodiments, the clothing processing device includes a clothing processing drum that can be driven to rotate, and a lifting rib is protruding from the inner wall of the clothing processing drum. A movable detection member is provided on the lifting rib. The detection member is used to detect the clothing in the clothing processing drum and output a parameter value representing the material of the clothing. By controlling the movement of the detection member, the detection member can be placed in different detection positions.

[0135] In some embodiments, the lifting rib has a lifting rib top surface in the protruding direction, and the lifting rib top surface is made of a transparent material;

[0136] The detection part includes an ultraviolet sensor and a push rod motor arranged inside the lifting rib, and the emission end of the ultraviolet sensor is opposite to the top end surface of the lifting rib;

[0137] The push rod motor can push and pull the ultraviolet sensor to move back and forth along the protruding direction of the lifting rib, so that the emitting end of the ultraviolet sensor is close to or away from the top end surface of the lifting rib, so as to adjust the detection position of the ultraviolet sensor.

[0138] Preferably, the above-mentioned clothes processing device is a drum-type washing machine.

[0139] In order to more clearly understand the working principle of the detection member in the embodiment of the present application, the structure of the detection member and the lifting rib is specifically described below:

[0140] The lifting ribs include the following components: an upper cover (i.e., a convex wall), a lower cover, a transparent cover (i.e., a light-transmitting plate), a DC motor, a gear screw, a support plate, an emitter and a receiver of an ultraviolet sensor, a magnet, and a proximity switch.

[0141] The following assembly relationship description:

[0142] The upper cover is matched with a transparent cover, and the transparent cover is installed just above the emitter and the receiver of the ultraviolet sensor.

[0143] A DC motor is arranged inside the lifting rib, the DC motor is coaxially linked with a gear, and a motor gland is arranged under the motor to fix the motor.

[0144] A gear screw is installed in front of the DC motor and moves in coordination with the gear on the motor.

[0145] A support plate is installed below the gear screw and moves in coordination with the gear screw.

[0146] The emitter and the receiver of the ultraviolet sensor are installed above the support plate, and the emitter and the receiver move synchronously with the support plate.

[0147] A magnet is installed on the side of the support plate to cooperate with the proximity switch detection.

[0148] There are three groups of proximity switches, which are installed in parallel with distances d1, d2, and d3 on the groove wall of the installation groove in the lifting rib.

[0149] The lower cover serves to fix the internal components of the lifting ribs and is fixed to the inner drum of the washing machine.

[0150] Instructions for achieving the movement of the UV sensor inside the lifting rib:

[0151] The main control board supplies power to the DC motor, and the rotor of the DC motor rotates, and the rotor drives the output shaft to rotate. After the output shaft rotates, the gear on the output shaft starts to rotate, thereby driving the gear of the screw rod to rotate. After the gear of the screw rod rotates, the screw rod also starts to rotate in a certain direction. After the screw rod rotates, the support plate on the screw rod rises or falls according to the direction of the screw rod rotation. When the screw rod rotates counterclockwise, the support plate on the screw rod starts to rise, and when the screw rod rotates clockwise, the support plate on the screw rod starts to fall. While the support plate rises or falls, combined with the magnet on the side of the support plate, after the magnet moves to the position of the three groups of proximity switches, the corresponding proximity switches are turned on. After observing which of the three groups of proximity switches is turned on, the specific position of the emitter and the receiver of the ultraviolet sensor can be determined, and then the distance between the ultraviolet sensor and the first wall can be determined. The top proximity switch corresponds to the distance d1 (10mm), the middle proximity switch corresponds to the distance d2 (15mm), and the bottom proximity switch corresponds to the distance d3 (20mm). Different test distances are required to test different materials in combination with the ultraviolet sensor, and then the material of the clothes in the barrel is detected by diffuse reflection after the ultraviolet light is powered on.

[0152] The DC motor has the function of forward and reverse control, which is achieved through different wiring methods and circuits. When rotating forward, the corresponding gear on the output shaft rotates clockwise, and when rotating reversely, the corresponding gear on the output shaft rotates counterclockwise. When the gear on the motor rotates clockwise, the lead screw gear is controlled to rotate counterclockwise to realize the lifting platform rising. When the gear on the motor rotates counterclockwise, the lead screw gear is controlled to rotate clockwise to realize the lowering of the lifting platform.
