Even if some washing machines have the function of detecting the material of the clothes, they mainly install a camera in the inner drum, first use the camera to capture the image of the clothes in the inner drum, and then analyze the material of the clothes based on the image of the clothes. However, due to the fixed position of the camera and the unadjustable shooting distance, this solution does not capture a comprehensive image of the clothes and cannot capture the clothes in the inner drum in all directions, resulting in the inability to accurately detect the material of the clothes and a narrow detection range.

[0072] Most of the existing drum washing machines do not have the function of detecting the material of the clothes in the inner drum. Even if some washing machines have the function of detecting the material of the clothes, they mainly install a camera in the inner drum, first use the camera to capture the image of the clothes in the inner drum, and then analyze the material of the clothes based on the image of the clothes. However, due to the fixed position of the camera and the unadjustable shooting distance, this solution does not capture a comprehensive image of the clothes and cannot capture the clothes in the inner drum in all directions, resulting in the inability to accurately detect the material of the clothes and a narrow detection range;

[0073] The present invention creatively provides a method for detecting clothing materials, which is used in clothing processing equipment; at least two detection components are arranged on the inner drum, each detection component has multiple detection positions, and the detection component can be adjusted to any detection position of the multiple detection positions; the detection method comprises: determining the parameter value of the detection component when it is in the detection position, and judging whether the parameter value meets the preset requirements; if yes, determining the material of the clothing in the inner drum according to the parameter value; if not, adjusting the detection position of the detection component or adjusting the position of the clothing in the inner drum until the parameter value meets the preset requirements, and then determining the material of the clothing in the inner drum; it can realize multi-dimensional, multi-directional and comprehensive detection of the material of the clothing in the inner drum, and improve the detection accuracy.

[0074] Example 1

[0075] like Figure 1 and Figure 2As shown, this embodiment provides a method for detecting clothing material, which is used in clothing processing equipment; preferably, the clothing processing equipment is a drum washing machine; the clothing processing equipment includes an inner drum, on which at least two detection members are arranged, the detection members are used to detect the clothing material in the inner drum, and each detection member has a plurality of detection positions, and the detection member can be adjusted to any detection position of the plurality of detection positions; when the detection member is in different detection positions, the radial distance between the detection member and the inner side wall of the inner drum is different; specifically, M lifting ribs are arranged on the inner drum; at least two of the M lifting ribs are each provided with a movable detection member; by controlling the movement of the detection member relative to the corresponding lifting rib, each detection member can be placed in a different detection position; wherein, M is a positive integer, and M≥3; preferably, M=3;

[0076] Detection methods include:

[0077] S1. Determine parameter values ​​of at least two detection elements at their detection positions, where the parameter values ​​are used to characterize the material of the clothes in the inner drum;

[0078] S2. Determine whether the parameter values ​​of at least two detection parts at the detection positions meet the preset requirements;

[0079] S3, if yes, determining the material of the clothes in the inner drum according to the parameter values ​​of at least two detection elements at the detection positions;

[0080] S4, which includes two parallel situations; the first situation is: if no, adjusting the detection position of at least one of the at least two detection members or adjusting the position of the clothes in the inner drum until the parameter values ​​of the at least two detection members at the detection positions meet the preset requirements, and determining the material of the clothes in the inner drum according to the latest parameter values ​​of the at least two detection members at the detection positions;

[0081] The second case is: if no, then adjusting the detection position of at least one of the at least two detection members or adjusting the position of the clothes in the inner drum until the number of adjustments reaches the threshold and the parameter values ​​of the at least two detection members at the detection positions still do not meet the preset requirements, determining the material of the clothes in the inner drum according to the parameter values ​​of the at least two detection members at the detection positions determined any one or more times (the second case);

[0082] The preset requirement is that the parameter values ​​of at least two detection elements at the detection position both fall within the corresponding preset material range and both point to different clothing materials;

[0083] For clothes of the same material, when the detection position of the detection element is different, the corresponding preset material intervals are different; different preset material intervals can point to different or the same clothing materials;

[0084] That is, when step S4 is the first case, after adjusting the detection position of the detection element or adjusting the position of the clothes in the inner drum, if the parameter value meets the preset requirements, the material of the clothes in the inner drum is determined according to the latest parameter value;

[0085] When step S4 is the second case, after adjusting the detection position of the detection element or adjusting the position of the clothes in the inner drum, the parameter value still does not meet the preset requirements, then it is judged that the clothes in the inner drum include clothes of the same material or large-volume clothes; at this time, the material of the clothes in the inner drum can be determined according to the parameter values ​​of at least two detection elements at the detection positions determined any one or more times (because the results of any one or more determinations are the same); of course, the type of material of the clothes detected is related to the number of detection elements, for example: if there are three detection elements, then there are two or one types of clothing materials detected; if there are two detection elements, then there is only one type of clothing material detected.

[0086] Furthermore, each detection member is slidably arranged on the corresponding lifting rib along the radial direction of the inner tube through a transmission assembly, the transmission assembly includes a push rod and a support frame, one end of the push rod is drivingly connected to the detection member driving motor, the other end of the push rod is provided with a support frame, the support frame is slidably arranged on the lifting rib, and the detection member is arranged on the support frame; when the detection member driving motor is running, the push rod moves with the support frame and the detection member;

[0087] The detection element is an ultraviolet sensor, which detects the material of the clothes in the inner drum by diffuse reflection, and finally identifies clothes of different materials according to the different degrees of ultraviolet absorption of different materials; the detection element drives the motor to adjust the position of the detection element on the lifting rib, and the detection results obtained when the detection element is in different detection positions are different; the detection element is adjusted to the optimal detection position by the detection element driving the motor, so that the detection element can detect clothes of different materials, avoid overlapping when detecting clothes of different materials, and more accurately distinguish clothes of different materials, thereby solving the problem that the existing drum washing machine cannot detect the material of clothes, and solves the problem that the detection distance in the existing drum washing machine cannot be adjusted and the clothes cannot be fully detected, resulting in low accuracy in detecting the material of clothes;

[0088] Multiple detection components detect the clothes in the inner drum at the same time, and the transmitter and the receiver of each detection component are arranged on the same horizontal plane; each detection component can be controlled to slide in the radial direction of the inner drum, so that each detection component can be adjusted to the best detection position to improve the detection accuracy.

[0089] Before washing, the clothes processing equipment controls the driving motor of the inner drum to make the inner drum rotate, detects the current of the driving motor of the inner drum, and determines whether there are clothes in the inner drum according to the current of the driving motor of the inner drum; when the current of the driving motor of the inner drum is greater than the preset current, it is determined that there are clothes in the driving inner drum.

[0090] It should be noted that the light signal of the ultraviolet sensor can generate diffuse reflection after contacting the clothing, and then the diffuse reflection parameter value can be obtained;

[0091] 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.

[0092] 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).

[0093] 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.

[0094] 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.

[0095] 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.

[0096] Example 2

[0097] Based on Example 1, this embodiment proposes that the preset requirement includes a first preset condition and a second preset condition, the first preset condition is that the parameter values ​​of at least two detection elements in the detection position fall within the corresponding preset material range, and the second preset condition is that the parameter values ​​of at least two detection elements in the detection position point to different clothing materials;

[0098] S2 includes:

[0099] S21, first determine whether the parameter values ​​of at least two detection elements in the detection position meet a first preset condition, and then determine whether the parameter values ​​of at least two detection elements in the detection position meet a second preset condition;

[0100] S22: If the parameter values ​​of the at least two detection elements in the detection positions meet the first preset condition and the second preset condition, the parameter values ​​of the at least two detection elements in the detection positions meet the preset requirements;

[0101] S23, if the parameter values ​​of the at least two detection elements in the detection position do not satisfy the first preset condition or satisfy the first preset condition but not the second preset condition, the parameter values ​​of the at least two detection elements in the detection position do not satisfy the preset requirement;

[0102] The following further describes step S21. In step S21, determining whether the parameter values ​​of at least two detection elements in the detection position meet the second preset condition includes:

[0103] S211, determining the clothing material pointed to by the parameter value of each detection element when it is in the detection position according to the preset material interval where the parameter values ​​of at least two detection elements when they are in the detection position are located;

[0104] S212: If the parameter values ​​of each detection element at the detection position indicate different clothing materials, the parameter values ​​of at least two detection elements at the detection positions meet the second preset condition;

[0105] S213: If the parameter values ​​of multiple detection elements in the at least two detection elements when they are in the detection position all point to the same clothing material, the parameter values ​​of the at least two detection elements when they are in the detection position do not satisfy the second preset condition.

[0106] The following further describes step S4. If the answer in S4 is no, adjusting the detection position of at least one of the at least two detection members until the parameter values ​​of the at least two detection members at the detection position meet the preset requirements includes:

[0107] S41, if the parameter values ​​of the at least two detection elements in the detection positions do not satisfy the first preset condition, adjusting the detection position of at least one of the at least two detection elements until the parameter values ​​of the at least two detection elements in the detection positions satisfy the first preset condition;

[0108] S42. If the parameter values ​​of the at least two detection elements in the detection positions meet the first preset condition but do not meet the second preset condition, adjust the detection position of at least one of the at least two detection elements until the parameter values ​​of the at least two detection elements in the detection positions meet the second preset condition.

[0109] Further, in S41, adjusting the detection position of at least one of the at least two detection members until the parameter values ​​of the at least two detection members at the detection position meet the first preset condition includes:

[0110] Determine whether the parameters of the test piece at the current test position are within the corresponding preset material range;

[0111] If yes, the detection element is controlled to remain at the current detection position;

[0112] If no, the detection member is controlled to move to one of the other detection positions;

[0113] Re-determine whether the parameter value of the test piece at the new test position is within the corresponding preset material range;

[0114] If yes, the detection part is controlled to remain in the new detection position;

[0115] If no, the detection member is re-controlled to move to another detection position among other detection positions;

[0116] The same process is repeated until the parameter value of each inspection piece at the inspection position falls within the corresponding preset material range.

[0117] Specifically, it is further explained by taking each detection member having three detection positions as an example, the three detection positions are respectively a first detection position, a second detection position and a third detection position, and the first detection position, the second detection position and the third detection position are arranged in the order that the radial distance between the detection member and the inner side wall of the inner cylinder gradually decreases; the initial detection position of the detection member is the first detection position;

[0118] Determine the parameter value a1 of the inspection piece at the initial inspection position, and judge whether a1 is within the corresponding preset material range;

[0119] If yes, the control detection member is kept in the first detection position;

[0120] If the answer is no, the detection member is controlled to move to the second detection position; the parameter value a2 of the detection member in the second detection position is re-determined, and it is determined whether a2 is within the preset material range; if the answer is yes, the detection member is controlled to remain in the second detection position; if the answer is no, the detection member is controlled to move to the third detection position; the parameter value a3 of the detection member in the third detection position is re-determined, and it is determined whether a3 is within the preset material range; if the answer is yes, the detection member is controlled to remain in the third detection position;

[0121] Or, if no, the detection member is controlled to move to the third detection position; the parameter value a3 of the detection member in the third detection position is re-determined, and it is determined whether a3 is within the preset material range; if yes, the detection member is controlled to remain in the third detection position; if no, the detection member is controlled to move to the second detection position; the parameter value a2 of the detection member in the second detection position is re-determined, and it is determined whether a2 is within the preset material range; if yes, the detection member is controlled to remain in the second detection position.

[0122] In addition, the detection positions of at least two detection elements are combined to form a plurality of combined detection positions; and in S42, adjusting the detection position of at least one detection element of the at least two detection elements until the parameter values ​​of the at least two detection elements at the detection positions meet the second preset condition includes:

[0123] Determine whether the parameters of at least two detection elements in the current combined detection position point to different clothing materials;

[0124] If yes, control at least two detection parts to remain in the current combined detection position;

[0125] If no, controlling at least two detection members to move to one of the other combination detection positions;

[0126] Re-determine whether the parameters of at least two detection elements at the new combined detection position point to different clothing materials;

[0127] If yes, controlling at least two detection parts to remain in a new combined detection position;

[0128] If no, re-controlling at least two detection members to move to another combination detection position among other combination detection positions;

[0129] The same process is repeated until the parameter values ​​of at least two detection elements at the combined detection positions point to different clothing materials.

[0130] Specifically, taking M=3 as an example, three lifting ribs are arranged on the inner cylinder at intervals along the circumferential direction of the inner cylinder, and a detection member is arranged on each of the three lifting ribs; the three detection members are provided with combination detection positions arranged in a preset order of a first combination detection position, a second combination detection position ... an Xth combination detection position;

[0131] Adjust the detection positions of the three detection elements to the first combination detection position, respectively determine the parameter values ​​of the three detection elements when they are in the first combination detection position, and determine whether the three parameter values ​​all point to different clothing materials;

[0132] If yes, the three detection elements are controlled to remain in the first combined detection position;

[0133] If not, the three detection members are controlled to move respectively, so that the detection positions of the three detection members are adjusted to the second combination detection position, the parameter values ​​of the three detection members at the second combination detection position are determined respectively, and it is determined whether the three new parameter values ​​all point to different clothing materials;

[0134] The same process can be carried out in this way until the three parameter values ​​at the combined detection positions of the three detection elements all point to different clothing materials.

[0135] In addition, when the detection positions of the three detection elements are adjusted to a certain combined detection position and it is determined that the three parameter values ​​all point to the same clothing material, it is determined that the materials of the clothing in the inner drum are the same or similar, or it is determined that the clothing is of the same material and has a large volume. The material of the clothing in the inner drum can be determined based on the three parameter values;

[0136] For example, a bulky garment made of the same material is a quilt, and the bulky garment may cover the surface of the lifting ribs.

[0137] Example 3

[0138] Based on Example 1, this embodiment proposes that if the answer in S4 is no, the position of the clothes in the inner drum is adjusted until the parameter values ​​of at least two detection elements at the detection positions meet the preset requirements, including:

[0139] Controlling the clothes processing equipment to execute a shaking program;

[0140] After the shaking-out procedure is completed, re-determine whether the parameter values ​​of at least two detection parts at the detection position meet the preset requirements;

[0141] If no, the clothes treating device is controlled to execute the shaking procedure again;

[0142] The same process is repeated until the parameter values ​​of at least two detection parts at the detection positions meet the preset requirements.

[0143] Taking M=3 as an example to further illustrate, three lifting ribs are arranged on the inner cylinder at intervals along the circumference of the inner cylinder, and a detection member is arranged on each of the three lifting ribs; the three detection members are respectively a first detection member, a second detection member and a third detection member;

[0144] The parameter value when the first detection element is in the detection position and the parameter value when the second detection element is in the detection position both point to the same clothing material, or the parameter value when the first detection element is in the detection position and the parameter value when the third detection element is in the detection position both point to the same clothing material, or the parameter value when the second detection element is in the detection position and the parameter value when the second detection element is in the detection position both point to the same clothing material, control the clothing processing equipment to execute the shaking program.

[0145] Example 4

[0146] On the basis of Embodiments 1 to 3, this embodiment proposes that S1 includes:

[0147] S11, when the detection element is in the detection position, the detection element is controlled to detect the material of the clothes in the inner drum N times to obtain N detection values;

[0148] S12, calculating the average value of N detection values;

[0149] S13, determining the parameter value of the detection part when it is in the detection position as the average value of N detection values;

[0150] Wherein, N is a positive integer, and N≥10.

[0151] In addition, the clothing processing device further comprises an outer drum, which is arranged around the outer side of the inner drum; before determining the parameter values ​​of at least two detection members at the detection positions, the detection method further comprises:

[0152] S011, obtaining the weight of the clothes in the inner drum;

[0153] S012. When the weight of the clothes in the inner drum is greater than the preset weight, the outer drum is first controlled to flow water so that the clothes in the inner drum absorb water, and then the outer drum is controlled to drain water (the inner drum does not rotate during this process); the clothes become heavier after absorbing water, which can prevent entanglement, and then the detection element on the lifting rib is used to perform detection through diffuse reflection;

[0154] Or, before determining the parameter values ​​of at least two detection members at the detection positions, the detection method further includes:

[0155] S021, control the inner drum to rotate, and obtain the current I of the inner drum drive motor 1;

[0156] S022, control the inner drum to stop rotating, first control the outer drum to let water in, so that the clothes in the inner drum absorb water, then control the outer drum to drain water (the inner drum does not rotate during this process), and then control the inner drum to rotate, and obtain the current I of the driving motor of the inner drum 2 ;

[0157] S023, according to the current I 1 and current I 2 Preliminarily determine the material of the clothes in the inner drum.

[0158] Specifically, according to the current I 1 and current I 2 The materials of the clothes in the inner tube are initially determined to include:

[0159] When the current I 2 is twice the current I 1 When making the clothes in the inner drum, make sure that the clothes in the inner drum are made of cotton or polyester.

[0160] When the current I 2 1.5 times the current I 1 When making the clothes in the inner tube, make sure that the material of the clothes is silk or linen;

[0161] First, similar materials are identified by weight, and the clothes are prevented from getting tangled. Then, the detection parts on the lifting ribs are used to further detect the material of the clothes.

[0162] Example 5

[0163] Different from the first to fourth embodiments, this embodiment provides a method for detecting clothing material, which is used in a clothing processing device; the clothing processing device comprises an outer drum and an inner drum, and three lifting ribs are arranged on the inner drum; each lifting rib is provided with a detection member;

[0164] The main control board determines whether the weight of the clothes in the inner drum is more than half-loaded by detecting the current of the driving motor of the inner drum. The initial radial distance between the three detection parts and the radial inner wall of the lifting rib is d1 (20mm). The three detection parts detect the clothes in the inner drum by diffuse reflection. Each detection part detects 10 times and obtains the respective average values ​​a, b, c, which are compared with the preset values ​​of d1 on the main control board.

[0165] When at least one of the average values ​​a, b, and c does not meet the preset value, after being fed back to the main control board, the main control board sends a signal to the detection part drive motor of the lifting rib that does not meet the preset value, and the detection part drive motor adjusts the ultraviolet sensor to the distance d2 (15mm) or d3 (10mm); after adjusting the distance, it is tested 10 times again, and the average value is taken. The obtained average value is compared with the preset value on the main control board again. After it is judged that it meets the range, the respective detection part drive motor does not need to adjust the distance again;

[0166] After determining that there is no need to adjust the detection distance of each detection element, a, b, and c that meet the preset values ​​are obtained and compared to determine whether a, b, and c are similar and within a preset material range; if at least two of them are the same and any two sets of data overlap, it is possible that the same large-area clothing is tested in this case, and the lifting ribs are covered by the same large clothing. At this time, this signal needs to be fed back to the main control board; after receiving the feedback, the main control board transmits the signal to the drive motor of the inner drum, and runs the shaking program to shake the clothes in the inner drum evenly; after completing this step, the three detection elements are tested again, and data is collected continuously for 10 times, and the average value is taken and compared with the preset value. If it meets the range, the material detection is completed. After performing enough material detections, the clothes in the inner drum are detected as much as possible, and when the values ​​of a, b and c are not in the same range, the washing can be started and the corresponding washing mode can be selected for washing; if the material of the clothing is detected to be special wool and silk, the washing machine starts to alarm, prompting the user to take out the clothing, and the washing machine cannot be used to wash clothing of special materials;

[0167] If the calculated average values ​​a, b, and c are all within a preset material range, there are two cases:

[0168] The first case is that the three detection components fail, or each detection component is at a different detection distance, resulting in the same detection interval; in this case, the detection component driving motor needs to be used to adjust the detection position of each detection component. The detection position combinations of the three detection components are (d1, d2, d3), (d2, d2, d3), (d3, d2, d3), (d1, d1, d3), (d1, d2, d3), (d1, d1, d1), (d2, d2, d2), (d3, d3, d3), (d2, d1, d3), (d3, d1, d3), (d2, d1, d2), (d2, d2, d1) and (d2, d2, d3), etc. Compare the different positions of the three detection components, and collect the appropriate interval amplitude change within the range of (-20, +20), then the interval state at this time is the best;

[0169] The second situation is that two large quilts of the same material may be placed in the inner drum (clothes of the same material are not limited to quilts). Similarly, it is necessary to adjust the appropriate distance multiple times. If the distance is adjusted and multiple data are collected, it can be determined that all the clothes or large objects placed in the inner drum are of the same material, completely covering the surfaces of the three lifting ribs.

[0171] This embodiment provides a clothes processing device, which includes an outer drum and an inner drum, wherein the inner drum is rotatably arranged in the outer drum, and a plurality of lifting ribs are arranged on the inner drum; at least two of the plurality of lifting ribs are each provided with a movable detection member; by controlling the movement of the detection member relative to the corresponding lifting rib, each detection member can be placed in a different detection position;
