For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Among the technologies related to clothing material detection, camera sampling technology is generally used. Intelligent camera identification of clothing material is a technology that integrates image recognition technology, deep learning algorithm and expert system. Camera sampling technology relies on deep learning algorithm and expert system to judge clothing material, and the accuracy of clothing material detection is relatively low.

[0046] Based on this, the following embodiments are proposed.

[0047] Embodiment 1:

[0048] like Figure 1 As shown, this embodiment provides a material detection method for identifying the material of clothes in a clothes processing drum of a clothes processing device, wherein a plurality of light signal detection elements are provided at different positions in the clothes processing drum, and a plurality of diffuse reflection parameter values ​​can be obtained when the clothes diffusely reflect the incident light signal through the light signal detection elements, and the distance between the light signal detection elements and the clothes in the clothes processing drum is adjustable, and the material detection method comprises:

[0049] Parameter acquisition step: acquiring first parameter intervals corresponding to the plurality of light signal detection elements, wherein the first parameter intervals are determined according to the plurality of diffuse reflection parameter values;

[0050] Judgment processing steps:

[0051] Determine whether there is an overlapping interval between the first parameter intervals corresponding to the plurality of optical signal detection elements,

[0052] If there are at least two optical signal detection elements, and the first parameter intervals corresponding to the two optical signal detection elements overlap, the distance between at least one of the at least two optical signal detection elements and the clothes in the clothes processing drum is adjusted, and the parameter acquisition step and the judgment processing step are repeated.

[0053] If there is no overlapping interval between the first parameter intervals corresponding to the multiple light signal detection components, the material of the clothing is determined according to the multiple diffuse reflection parameter values ​​corresponding to the multiple light signal detection components.

[0054] In the present embodiment, the method for detecting clothing material consists of a parameter acquisition step and a judgment processing step. In the parameter acquisition step, multiple first parameter intervals are acquired. In the judgment processing step, it is judged whether there are overlapping intervals in the multiple first parameter intervals. If there are at least two optical signal detection elements and their corresponding first parameter intervals have overlapping intervals, it will cause inaccurate clothing material detection. By adjusting the distance between the optical signal detection element and the clothing, the probability of overlapping of multiple first parameter intervals is reduced. When there is no overlapping interval in the first parameter interval, the degree of overlap in clothing material detection is reduced. The present material detection method gradually adjusts the distance between the optical signal detection element and the clothing as mentioned above so that there is a suitable distance between the optical signal detection element and the clothing. This can not only reduce the degree of overlap in clothing material detection and improve the accuracy of material detection, but also ensure the validity of subsequent parameter values, reduce the number of repeated detections, and reduce the time required for clothing material detection, so as to accurately and efficiently detect clothing materials.

[0055] The method for adjusting the distance between the optical signal detector and the clothes can be: the optical signal detector is set in the lifting rib, and the lifting rib is used in the treatment tube of the clothes processing equipment as an example, the lifting rib includes a lifting rib body and a support plate; the lifting rib body has: a convex wall protruding from the inner wall of the treatment tube to the inside of the treatment tube, and an installation space formed inside the convex wall; the support plate is movably arranged in the installation space, and a detection member for optical signal detection is arranged on the support plate; wherein the convex wall has a light-transmitting portion at least in the part opposite to the detection member for the detection member to perform optical signal detection. The extension direction of the convex wall formed by the lifting rib body is used as the height direction of the lifting rib body, and the installation space is formed inside the convex wall. The installation space and the inside of the treatment tube can be two spaces that are not connected or can be connected. The support plate is located in the installation space and can move, and the support plate moves along the height direction of the lifting rib body. The support plate can reciprocate along the height direction of the lifting rib body in the installation space, thereby driving the detection member to reciprocate along the height direction of the lifting rib body, so as to gradually adjust the distance between the optical signal detector and the clothes. In this embodiment, the distance between the optical signal detection element and the clothing may be the distance between the lifting rib and the upper edge of the convex wall.

[0056] Those skilled in the art should understand that in one embodiment of the present application, when the optical signal detection element is arranged inside the lifting rib, the distance between the optical signal detection element and the clothing substantially depends on the optical signal emission and reception direction of the optical signal detection element and the distance between the optical signal detection element and the outer wall of the lifting rib (the side wall in contact with the clothing).

[0057] Optionally, in an implementation of this embodiment,

[0058] When adjusting the distance between at least one of the at least two optical signal detection elements and the clothes in the clothing treatment drum, the overlapping interval is compared with a preset overlapping interval. The greater the difference between the maximum value and the minimum value of the overlapping interval compared to the difference between the maximum value and the minimum value of the preset overlapping interval, the greater the distance between the adjusted optical signal detection element and the clothes in the clothing treatment drum.

[0059] In this embodiment, the greater the difference between the maximum value and the minimum value of the overlapping interval compared to the difference between the maximum value and the minimum value of the preset overlapping interval, the greater the possibility that the multiple first parameter intervals have a larger overlapping range. In this case, by adjusting the distance between the optical signal detection element and the clothing to be larger, the multiple first parameter intervals are made to have no overlapping intervals in the fastest way, thereby achieving faster adjustment of the optical signal detection element.

[0060] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0061] The obtaining of the first parameter intervals corresponding to the plurality of optical signal detection components respectively comprises:

[0062] The optical signal detection element is controlled to repeatedly obtain multiple optical signals, each optical signal corresponds to a first parameter value, and a minimum value and a maximum value are selected from multiple first parameter values ​​to form a first parameter interval.

[0063] In this embodiment, multiple first parameter values ​​are obtained by repeatedly acquiring multiple optical signals through the optical signal detection component, and the minimum value and the maximum value are selected from the multiple first parameter values ​​to form a first parameter interval. Among the multiple first parameter values, the minimum value and the maximum value are used as the end values ​​of the first parameter interval, so that the first parameter interval is more accurate, and the overlapping intervals obtained by comparing two by two in the multiple first parameter intervals are also more accurate.

[0064] Optionally, in an implementation of this embodiment,

[0065] The number of optical signal detection elements is n, n≥2, and the n optical signal detection elements are sequentially distributed along the circumference of the clothing processing drum in the clothing processing device, and each optical signal detection element includes an emitting electrode and a receiving electrode;

[0066] The parameter acquisition step and / or judgment processing step include: controlling the emitter of any one of the n optical signal detection elements to emit an optical signal to the clothes in the laundry processing drum, and controlling the receiver of any one of the optical signal detection elements to receive the optical signal reflected by the clothes in the laundry processing drum.

[0067] In this embodiment, n=3, three optical signal detection components are arranged in a ring shape in the clothing processing drum to perform multi-angle detection on the clothes in the clothing processing drum, each optical signal detection component is responsible for obtaining a parameter value interval, and three overlapping intervals are obtained based on the mutual comparison between the three first parameter intervals. The three overlapping intervals are compared with the preset overlapping intervals, and the distance between the optical signal detection component and the clothes is adjusted to ensure that there is an appropriate distance between the optical signal detection component and the clothes.

[0068] The three optical signal detection components include a first optical signal detection component, a second optical signal detection component and a third optical signal detection component, wherein the first optical signal detection component includes a first emitter and a first receiver, the second optical signal detection component includes a second emitter and a second receiver, and the third optical signal detection component includes a third emitter and a third receiver.

[0069] Acquiring multiple first parameter intervals includes controlling the first emitter, the second emitter and the third emitter to emit light signals to the clothes in the clothes processing device, controlling the first receiver to receive the light signal emitted by the first emitter reflected by the clothes in the clothes processing drum, controlling the second receiver to receive the light signal emitted by the second emitter reflected by the clothes in the clothes processing drum, and controlling the third receiver to receive the light signal emitted by the third emitter reflected by the clothes in the clothes processing drum, wherein the light signal emitted by the emitter will pass through the clothes in the clothes processing drum, wherein a part of the light signal is blocked and reflected by the clothes and received by the corresponding receiver, a part of the light signal is absorbed by the clothes, and another part of the light signal penetrates the clothes, and clothes of different materials have different reflection capabilities for light signals, so different first parameter values ​​can be obtained when the clothes are of different materials, and the end value is selected in the first parameter value as the first parameter interval. It is simple and easy to operate, and has high accuracy.

[0070] Specifically, the first optical signal detection element is controlled to repeatedly obtain multiple first optical signals, each first optical signal corresponds to a first parameter value A, and a minimum value and a maximum value are selected from the multiple first parameter values ​​A to form a first parameter interval A;

[0071] Control the second optical signal detection element to repeatedly acquire multiple second optical signals, each second optical signal corresponds to a first parameter value B, and select a minimum value and a maximum value from the multiple first parameter values ​​B to form a first parameter interval B;

[0072] Control the third optical signal detection element to repeatedly acquire multiple third optical signals, each third optical signal corresponds to a first parameter value C, and select a minimum value and a maximum value from the multiple first parameter values ​​C to form a first parameter interval C;

[0073] The overlapping interval includes a first overlapping interval, a second overlapping interval and a third overlapping interval. The first overlapping interval is the overlapping interval of the first parameter interval A and the first parameter interval B, the second overlapping interval is the overlapping interval of the first parameter interval A and the first parameter interval C, and the third overlapping interval is the overlapping interval of the first parameter interval B and the first parameter interval C.

[0074] More specifically, the preset overlap interval includes a first preset overlap interval, a second preset overlap interval, a third preset overlap interval and a fourth preset overlap interval, the first preset overlap interval is 0 to 20, the second preset overlap interval is 21 to 40, the third preset overlap interval is 41 to 60, and the fourth preset overlap interval is 61 to 430;

[0075] If the first overlapping interval is within the fourth preset overlapping interval, the second overlapping interval is within the fourth preset overlapping interval, and the third overlapping interval is within the fourth preset overlapping interval, then the distance between the first optical signal detector and the clothes in the laundry processing drum is increased to the preset distance a, the distance between the second optical signal detector and the clothes in the laundry processing drum is increased to the preset distance a, and the distance between the third optical signal detector and the clothes in the laundry processing drum is increased to the preset distance a;

[0076] If the first overlapping interval is within the third preset overlapping interval, the second overlapping interval is within the third preset overlapping interval, and the third overlapping interval is within the third preset overlapping interval, the distance between the first optical signal detector and the clothes in the laundry processing drum is increased to a preset distance a and / or the distance between the second optical signal detector and the clothes in the laundry processing drum is increased to a preset distance a;

[0077] If the first overlapping interval is within the second preset overlapping interval, the second overlapping interval is within the second preset overlapping interval, and the third overlapping interval is within the second preset overlapping interval, then the distance between the first optical signal detector and the clothes in the laundry processing drum is increased to the preset distance b, the distance between the second optical signal detector and the clothes in the laundry processing drum is increased to the preset distance b, and the distance between the third optical signal detector and the clothes in the laundry processing drum is increased to the preset distance b;

[0078] If the first overlapping interval is within the first preset overlapping interval, the second overlapping interval is within the first preset overlapping interval, and the third overlapping interval is within the first preset overlapping interval, then the distance between the first optical signal detector and the clothes in the laundry processing drum is increased to the preset distance c, the distance between the second optical signal detector and the clothes in the laundry processing drum is increased to the preset distance c, and the distance between the third optical signal detector and the clothes in the laundry processing drum is increased to the preset distance c; wherein,

[0079] Preset distance a>preset distance b>preset distance c.

[0080] Among them, the preset distance a=20 mm, the preset distance b=15 mm, and the preset distance c=10 mm.

[0081] In this embodiment, if the first overlapping interval, the second overlapping interval and the third overlapping interval are all located at 61-430, in this state, the first parameter interval A, the first parameter interval B and the first parameter interval C all have large overlapping intervals with each other, and the distance between the first optical signal detection element and the clothes in the clothing treatment drum is increased to 20 mm, the distance between the second optical signal detection element and the clothes in the clothing treatment drum is increased to 20 mm, and the distance between the third optical signal detection element and the clothes in the clothing treatment drum is increased to 20 mm, so as to reduce the probability of overlapping of multiple first parameter intervals. When there is no overlapping interval in the first parameter interval, The overlapping degree of clothing material detection is reduced, and the accuracy of material detection is improved. At this time, the preset target intervals corresponding to each material are: cotton material 100-130, linen material 135-155, wool material 190-230, silk material 165-189, polyester fiber 290-330, chemical fiber material 335-390, and the distance between the three optical signal detection components and the clothing is 20 mm. The preset target interval range corresponding to each material is narrow, and the overlapping interval of multiple first parameter intervals is reduced, that is, the overlapping degree of clothing material detection is reduced, and the accuracy of clothing material detection is improved.

[0082] If the first overlapping interval is located at, the second overlapping interval and the third overlapping interval are all located at 41-60, in this state, the first parameter interval A, the first parameter interval B and the first parameter interval C all have a large overlapping interval with each other, and the distance between the first optical signal detector and the clothes in the clothing processing drum can be increased to 20 mm individually or the distance between the first optical signal detector and the second optical signal detector and the clothes in the clothing processing drum can be increased to 20 mm.

[0083] If the first overlapping interval, the second overlapping interval, and the third overlapping interval are all between 21 and 40, in this state, the overlapping intervals between the first parameter interval A, the first parameter interval B, and the first parameter interval C are small, and the distance between the first optical signal detection component and the clothes in the clothing processing drum can be adjusted to increase to 15 mm, the distance between the second optical signal detection component and the clothes in the clothing processing drum can be adjusted to increase to 15 mm, and the distance between the third optical signal detection component and the clothes in the clothing processing drum can be adjusted to increase to 15 mm. At this time, the preset target intervals corresponding to each material are: the preset target intervals corresponding to each material are: cotton material 80-150, linen material 115-175, wool material 170-250, silk material 145-209, polyester fiber material 270-350, and chemical fiber material 315-410. While ensuring a low degree of overlap in clothing material detection, the range of the preset target intervals corresponding to each material is increased, which can improve the effectiveness of subsequent parameter values, reduce the number of repeated detections, and reduce the time required for clothing material detection, so as to accurately and efficiently detect clothing materials.

[0084] If the first overlapping interval, the second overlapping interval, and the third overlapping interval are all between 0 and 20, in this state, the overlapping intervals between the first parameter interval A, the first parameter interval B, and the first parameter interval C are very small, and the distance between the first optical signal detection component and the clothes in the clothing processing drum can be adjusted to increase to 10 mm, the distance between the second optical signal detection component and the clothes in the clothing processing drum can be adjusted to increase to 10 mm, and the distance between the third optical signal detection component and the clothes in the clothing processing drum can be adjusted to increase to 10 mm. At this time, the preset target intervals corresponding to each material are: cotton material 60-170, linen material 95-195, wool material 150-280, silk material 125-229, polyester fiber 250-370, and chemical fiber material 295-430. While ensuring a low degree of overlap in clothing material detection, the preset target interval range corresponding to each material is increased, which can improve the effectiveness of subsequent parameter values, reduce the number of repeated detections, and reduce the time required for clothing material detection, so as to accurately and efficiently detect clothing materials.

[0085] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0086] In the determination processing step, determining the material of the clothing according to the plurality of diffuse reflection parameter values ​​corresponding to the plurality of light signal detection elements respectively includes:

[0087] Determining the clothing material according to the multiple diffuse reflection parameter values ​​corresponding to each of the multiple light signal detection components includes controlling the multiple light signal detection components to repeatedly obtain multiple light signals, each light signal corresponds to a second sub-parameter value, calculating the average value of the multiple second sub-parameter values ​​obtained by each light signal detection component to obtain multiple second parameter values, and determining the clothing material according to the preset target intervals corresponding to the multiple second parameter values ​​and the clothing material corresponding to the preset target intervals.

[0088] In this embodiment, the second parameter value is obtained by calculating the average value of multiple second sub-parameter values, which can further improve the accuracy of the second parameter value, determine the preset target interval where the second parameter value is located, and finally determine the clothing material based on the correspondence between the preset target interval and the clothing material.

[0089] Embodiment 2

[0090] This embodiment provides a material detection device, which is arranged in a clothes processing drum of a clothes processing device, and includes:

[0091] n optical signal detection elements, each optical signal detection element comprises an emitting electrode and a receiving electrode, n≥2;

[0092] The n optical signal detectors are configured such that an emitter of any of the n optical signal detectors emits an optical signal to the clothes in the clothes processing tub, and a receiver of any of the optical signal detectors receives an optical signal reflected by the clothes in the clothes processing tub.

[0093] n lifting ribs, the n lifting ribs correspond to the n optical signal detection elements one by one, and the emitter and the receiver in the same optical signal detection element are arranged flat on the corresponding lifting ribs;

[0094] A driving member is drivingly connected to the optical signal detecting member and is used to drive the optical signal detecting member to move so as to adjust the distance of the optical signal detecting member relative to the clothes in the clothes processing tub.

[0095] In this embodiment, in this embodiment, n=3, the three optical signal detection components include a first optical signal detection component, a second optical signal detection component and a third optical signal detection component, wherein the first optical signal detection component includes a first emitter and a first receiver, the second optical signal detection component includes a second emitter and a second receiver, and the third optical signal detection component includes a third emitter and a third receiver,

[0096] Obtaining the first parameter intervals corresponding to each of the multiple optical signal detection elements includes controlling the first emitter, the second emitter and the third emitter to emit optical signals to the clothes in the clothing processing device, controlling the first receiver to receive the optical signal emitted by the first emitter and reflected by the clothes in the clothing processing drum, controlling the second receiver to receive the optical signal emitted by the second emitter and reflected by the clothes in the clothing processing drum, and controlling the third receiver to receive the optical signal emitted by the third emitter and reflected by the clothes in the clothing processing drum, wherein the optical signal emitted by the emitter will pass through the clothes in the clothing processing drum, wherein a part of the optical signal is blocked and reflected by the clothes and received by the corresponding receiver, a part of the optical signal is absorbed by the clothes, and another part of the optical signal penetrates the clothes, and clothes of different materials have different reflection capabilities for optical signals, so different first parameter values ​​can be obtained when the clothes are of different materials, and the end value is selected from the first parameter value as the first parameter interval.

[0097] Determining the clothing material based on the multiple diffuse reflection parameter values ​​corresponding to the multiple light signal detection components includes obtaining the final second parameter value by taking the average or median. The above method of obtaining the second parameter value representing the clothing is simple and easy with high accuracy.

[0098] The driving member may include a driving motor, a screw rod, a push block and a gear. The driving motor drives the gear to rotate to drive the screw rod. The rotation of the screw rod forces the push block on it to move, driving the light signal detection member to move. By driving the light signal detection member to move toward the surface of the lifting rib, the distance between the light signal detection member and the surface of the lifting rib is reduced, and the distance between the light signal detection member and the clothing is reduced. Similarly, by driving the light signal detection member to move away from the surface of the lifting rib, the distance between the light signal detection member and the surface of the lifting rib is increased, and the distance between the light signal detection member and the clothing is increased. Therefore, the material detection device can reduce the overlap of clothing material detection and improve the accuracy of clothing material detection by adjusting the distance between the light signal detection member and the clothing. It can also ensure the validity of the second parameter value, reduce the number of repeated detections, and reduce the time required for clothing material detection, so as to accurately and efficiently detect clothing materials.

[0099] Optionally, in an implementation of this embodiment,

[0100] The optical signal detection component is an ultraviolet sensor, the emitter is an ultraviolet sensor emitter, and the receiver is an ultraviolet sensor receiver.

[0101] When the optical signal detection element is an ultraviolet sensor, the emitter is an ultraviolet sensor emitter, and the wavelength of the optical signal emitted by the emitter is 100 to 400 nm.

[0102] It should be noted that, in an 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.

[0103] 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.

[0104] In an embodiment, the preset calculation formula for calculating the diffuse reflection parameter value may 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 (light intensity related).

[0105] In the embodiment, in order to determine the material of the 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.

[0106] 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.

[0107] 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.
