[0092] In the related technology of washing machines, the clothes in the clothes processing drum are generally washed using several inherent washing modes, and it is impossible to detect and protect clothes of different materials in a targeted manner, which leads to different degrees of damage to the clothes during the washing process.

[0093] Based on this, the following embodiments are proposed.

[0094] Embodiment 1:

[0095] like Figure 1 As shown, this embodiment provides a material detection method for identifying the material of clothes in a clothes processing device. The material detection method includes:

[0096] Obtaining a first parameter value characterizing a material of clothing and determining whether the first parameter value is within a preset target range, wherein the first parameter value is determined based on an optical signal collected by an optical signal detection component in a first optical signal detection mode, and the optical signal detection component is fixedly disposed in a clothing processing drum of a clothing processing device;

[0097] If the first parameter value is within the target interval, the clothing material is determined according to the first parameter value and the corresponding relationship between the target interval and the clothing material to obtain a first clothing material detection result; and / or,

[0098] If the first parameter value is not within the target interval, then:

[0099] After controlling the clothes processing drum to rotate, reacquiring the first parameter value, and re-determining whether the first parameter value is within a preset target range;

[0100] Wherein, the first optical signal detection mode includes:

[0101] The first emitter in the optical signal detection element emits an optical signal penetrating the clothing toward the second receiving electrode along a first direction and the optical signal is received by the second receiving electrode.

[0102] In this embodiment, the first emitter is controlled to emit a light signal that penetrates clothes toward the second receiver along a first direction and is received by the second receiver. The light signal emitted by the first emitter passes through the clothes in the clothing processing drum. A part of the light signal is blocked and absorbed by the clothes, and another part of the light signal penetrates the clothes and is received by the receiver. The light signal has different penetrating abilities for clothes of different materials. The difference in the penetrating abilities of the light signal for clothes of different materials can be used to determine the material of the clothes in the clothing processing drum. The material of the clothes can be identified by the first optical signal detection mode. This not only realizes a simple related structure for detection but also has high recognition accuracy.

[0103] Specifically, if the first parameter value is not within the target range, it proves that the detection is wrong.

[0104] After controlling the clothes processing drum to rotate, the clothes in the clothes processing drum are turned over, the position of the clothes is adjusted, the first parameter value is re-acquired, and it is re-determined whether the first parameter value is within a preset target range, and so on, until it is detected that the first parameter value is within a preset target range;

[0105] If the first parameter value is within the target range, the clothing material is determined based on the first parameter value and the correspondence between the target range and the clothing material, and the first clothing material detection result is obtained, thereby providing accurate and comprehensive data for selecting different washing modes for clothing of different materials, so that clothing of different materials can be detected and protected in a targeted manner.

[0106] Optionally, in an implementation of this embodiment, as Figure 3-5 As shown,

[0107] Obtaining a first parameter value representing the material of clothing includes:

[0108] When the laundry treatment drum is stationary, the parameter values ​​of the light signal received by the second receiving electrode in the first light signal detection mode are obtained multiple times.

[0109] A first parameter value is obtained by calculation according to a plurality of parameter values.

[0110] Specifically, according to the optical signal received by the second receiving electrode, the parameter value a is obtained, and a parameter value a is obtained every 0.5s. 20 parameter values ​​a are repeatedly obtained, and the 20 parameter values ​​a are arranged from small to large. After the arrangement is completed, the median an of the 20 parameter values ​​a is taken, and an is compared with a preset target interval, wherein the preset target interval can be A±20, B±20, C±20, D±20, and E±20, which correspond to the parameter intervals of 5 conventional clothing materials, namely, cotton, wool, silk, polyester, and linen, respectively. According to the parameter value a n And the target interval in which it is located, determine the corresponding clothing material, thereby providing accurate and comprehensive data for selecting different washing modes for clothing of different materials, so that clothing of different materials can be tested and protected in a targeted manner.

[0111] Optionally, in an implementation of this embodiment, as Figure 2 As shown,

[0112] If the first parameter value is within the target range, the material detection method further includes:

[0113] Obtaining a second parameter value representing the material of the clothing and determining whether the second parameter value is within a preset target range, the second parameter value being determined based on a light signal collected by the light signal detection component in a second light signal detection mode;

[0114] If the second parameter value is within the target interval, the clothing material is determined according to the second parameter value and the corresponding relationship between the target interval and the clothing material to obtain a first clothing material detection result; and / or,

[0115] If the second parameter value is not within the target range, the clothes processing drum is controlled to rotate, the second parameter value is acquired again, and it is determined again whether the second parameter value is within the preset target range;

[0116] Among them, the second optical signal detection mode includes: the first emitter in the optical signal detection element emits an optical signal that penetrates the clothes to the third receiving electrode along the second direction and is received by the third receiving electrode, the second direction is different from the first direction, and the third receiving electrode is different from the second receiving electrode.

[0117] A final clothing material detection result is determined according to the first clothing material detection result and the second clothing material detection result.

[0118] In the present embodiment, the material detection method preferably adopts a first light signal detection mode combined with a second light signal detection mode. More specifically, adjacent light signal detection components are first controlled to transmit and receive light signals to obtain multiple first parameter values, and then it is determined whether the multiple first parameter values ​​are within a preset target range. The corresponding clothing material is determined according to the preset target range in which the multiple parameter values ​​are located. If all three parameter values ​​are not within the preset target range, the clothing processing drum is controlled to rotate at a target speed for a target time and then stop rotating, and multiple parameter values ​​are re-obtained. It is also determined whether the multiple parameter values ​​are within the preset target range. If the multiple parameter values ​​are within the preset target range, the corresponding clothing material is temporarily stored, and the relative light signal detection components are continuously controlled to transmit and receive light signals to obtain multiple second parameter values, and the multiple second parameter values ​​are determined. Whether it is within the preset target interval, and the corresponding clothing material is determined according to the preset target interval where the multiple second parameter values ​​are located. If the multiple second parameter values ​​are not within the preset target interval, the clothing treatment drum is controlled to rotate at the target speed for the target time and then stop rotating, and the multiple second parameter values ​​are re-obtained, and the multiple second parameter values ​​are re-determined whether they are within the preset target interval. If the multiple second parameter values ​​are within the preset target interval, the corresponding clothing material is temporarily stored, and multiple clothing material information is obtained through the detection method of adjacent and opposite shooting between the optical signal detection parts. For example, if the detected clothing material information is composed of 3 times cotton and 2 times polyester fiber, the cotton washing mode can be selected to wash, mainly to protect cotton clothing. If wool material is detected, an alarm can be issued to prompt the user to take out the wool clothing that cannot be washed. The clothing in the clothing treatment drum is fully covered by adjacent shooting and opposite shooting, and the parameter values ​​are further fully obtained, so that the first parameter value and the second parameter value obtained are more accurate. The combination of the first optical signal detection mode and the second optical signal detection mode used is more sufficient and accurate for clothing material detection.

[0119] Optionally, in an implementation of this embodiment, as Figure 3-5 As shown,

[0120] 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 emitter and a receiver;

[0121] The first optical signal detection mode includes: controlling the emitter of any one of the n optical signal detection elements to emit an optical signal to the clothes in the clothing processing device, and controlling the receiving electrode of the optical signal detection element other than any one of the optical signal detection elements to receive the optical signal transmitted through the clothes in the clothing processing device (technical personnel in this field should understand that, at the same time, only the receiving electrode of one detection element receives the optical signal emitted by an emitter of any one of the optical signal detection elements).

[0122] In this embodiment, the first optical signal detection mode preferably adopts the method of detecting the clothing material by the optical signal penetrating the clothing. The emitters of the n optical signal detectors can respectively emit optical signals to the receivers in the optical signal detectors other than themselves, thereby forming a circular and intersecting optical signal network in the clothing treatment cylinder, comprehensively covering the clothing in the clothing treatment cylinder, and more comprehensively obtaining the parameter value a, so that the obtained parameter value a n is more accurate. Therefore, the first optical signal detection mode adopted is more sufficient and accurate for detecting the clothing material.

[0123] Optionally, in an implementation manner of this embodiment, as Figure 3-5 shown,

[0124] the number of optical signal detectors is set to n, n≥3, and the n optical signal detectors are sequentially distributed along the circumferential direction of the clothing treatment cylinder in the clothing treatment device. Each optical signal detector includes an emitter and a receiver.

[0125] The first optical signal detection mode includes:

[0126] The receiver of the (i + 1)-th optical signal detector receives the optical signal emitted by the emitter of the i-th optical signal detector, and the emitter of the (i + 1)-th optical signal detector emits an optical signal to the receiver of the (i + 2)-th optical signal detector.

[0127] The second optical signal detection mode includes:

[0128] The receiver of the (i + a)-th optical signal detector receives the optical signal emitted by the emitter of the i-th optical signal detector, and the emitter of the (i + a)-th optical signal detector emits an optical signal to the receiver of the (i + 2a)-th optical signal detector;

[0129] wherein, i is a positive integer. When the n optical signal detectors are sequentially arranged along the circumferential direction of the clothing treatment cylinder, i represents the serial number when the optical signal detectors are circularly counted along the circumferential direction, 1 < a < n, and a is a positive integer;

[0130] Obtaining the first parameter value characterizing the clothing material includes:

[0131] When the clothing treatment cylinder is stationary, the parameter values of the optical signals received by the n receivers in the first optical signal detection mode are obtained multiple times to obtain n groups of parameter values, and n first parameter values are calculated according to the n groups of parameter values;

[0132] The first parameter value being within the target interval includes:

[0133] At least one of the n first parameter values is within the target interval.

[0134] The cycle count refers to the continuous accumulation count of circles.

[0135] For example, n = 2, such as Figure 5 As shown, one cycle counting method is 1 (optical signal detection element 1), 2 (optical signal detection element 2), 3 (optical signal detection element 1), 4 (optical signal detection element 2), 5 (optical signal detection element 1), 6 (optical signal detection element 2)...

[0136] like Figure 1 As shown, when i=1, the receiving electrode of the second optical signal detector (optical signal detector 2) is used to receive the optical signal emitted by the emitting electrode of the first optical signal detector (optical signal detector 1), and the emitting electrode of the second optical signal detector (optical signal detector 2) is used to emit the optical signal to the receiving electrode of the third optical signal detector (optical signal detector 1). Thus, mutual transmission and reception between the emitting electrode 2 and the receiving electrode 3 in the two optical signal detectors are formed.

[0137] For example, when n=3, Figure 3 Or as shown in 4, a cycle counting method is 1 (optical signal detection element 1), 2 (optical signal detection element 2), 3 (optical signal detection element 3), 4 (optical signal detection element 1), 5 (optical signal detection element 2), 6 (optical signal detection element 3)...

[0138] When i=1, the receiving electrode of the second optical signal detector (optical signal detector 2) is used to receive the optical signal emitted by the emitting electrode of the first optical signal detector (optical signal detector 1), the emitting electrode of the second optical signal detector (optical signal detector 2) is used to emit an optical signal to the receiving electrode of the third optical signal detector (optical signal detector 3), and the emitting electrode of the third optical signal detector (optical signal detector 3) is used to emit an optical signal to the receiving electrode of the fourth optical signal detector (optical signal detector 1). Thus, mutual transmission and reception between adjacent emitting electrodes 2 and receiving electrodes 3 in the three optical signal detectors are formed.

[0139] For example, when n=4, a cyclic counting method is 1 (optical signal detection element 1), 2 (optical signal detection element 2), 3 (optical signal detection element 3), 4 (optical signal detection element 4), 5 (optical signal detection element 1), 6 (optical signal detection element 2), 7 (optical signal detection element 3), 8 (optical signal detection element 4)...

[0140] When i=1 and a=2, the receiving electrode of the third optical signal detection element (optical signal detection element 3) is used to receive the optical signal emitted by the emitting electrode of the first optical signal detection element (optical signal detection element 1), and the emitting electrode of the third optical signal detection element (optical signal detection element 3) is used to emit the optical signal to the receiving electrode of the fifth optical signal detection element (optical signal detection element 1);

[0141] When i=2 and a=2, the receiving electrode of the fourth optical signal detector (optical signal detector 4) is used to receive the optical signal emitted by the emitting electrode of the second optical signal detector (optical signal detector 2), and the emitting electrode of the fourth optical signal detector (optical signal detector 4) is used to emit the optical signal to the receiving electrode of the sixth optical signal detector (optical signal detector 2). Thus, mutual transmission and reception between the relative emitting electrodes 2 and receiving electrodes 3 in the four optical signal detectors are formed.

[0142] It can be seen from this embodiment that among the n optical signal detection components, the first optical signal detection mode is the mutual transmission and reception of optical signals between adjacent emitters and receivers, and the second optical signal detection mode is the mutual transmission and reception of optical signals between relative emitters and receivers. The n first parameter values ​​and n second parameter values ​​obtained in the two modes come from multiple transmission directions and multiple reception directions, and are used to determine the clothing material with high accuracy.

[0143] Optionally, in an implementation of this embodiment, as Figure 2 , 3 , 4,

[0144] The optical signal detection element comprises a first optical signal detection element, a second optical signal detection element and a third optical signal detection element which are sequentially distributed along the circumference of the laundry processing drum in the laundry processing device, the first optical signal detection element comprises a first emitter 201 and a first receiver 301, the second optical signal detection element comprises a second emitter 202 and a second receiver 302, and the third optical signal detection element comprises a third emitter 203 and a third receiver 303;

[0145] The first optical signal detection mode includes:

[0146] Control the first emitter 201 to transmit an optical signal to the third receiver 303, and the third receiver 303 receives the optical signal emitted by the first emitter 201 to obtain the parameter value a 1 , repeatedly obtain multiple parameter values ​​a 1 , and according to multiple parameter values ​​a 1 Calculate the parameter value a n1 ; Control the third emitter 203 to transmit an optical signal to the second receiving electrode 302, and the second receiving electrode 302 receives the optical signal emitted from the third emitter 203 to obtain the parameter value a 2 , repeatedly obtain multiple parameter values ​​a 2 , and according to multiple parameter values ​​a 2 Calculate the parameter value a n2 ; Control the second emitter 202 to transmit an optical signal to the first receiving electrode 301, and the first receiving electrode 301 receives the optical signal emitted from the second emitter 202 to obtain the parameter value a 3 , repeatedly obtain multiple parameter values ​​a3 , and according to multiple parameter values ​​a 3 Calculate the parameter value a n3 ;

[0147] The second optical signal detection mode includes:

[0148] Control the first emitter 201 to transmit an optical signal to the second receiver 302, and the second receiver 302 receives the optical signal emitted by the first emitter 201 to obtain the parameter value a 4 , repeatedly obtain multiple parameter values ​​a 4 , and according to multiple parameter values ​​a 4 Calculate the parameter value a n4 ; Control the third emitter 203 to transmit an optical signal to the first receiving electrode 301, and the first receiving electrode 301 receives the optical signal emitted from the third emitter 203 to obtain the parameter value a 5 , repeatedly obtain multiple parameter values ​​a 5 , and according to multiple parameter values ​​a 5 Calculate the parameter value a n5 ; Control the second emitter 202 to transmit an optical signal to the third receiver 303, and the third receiver 303 receives the optical signal emitted from the second emitter 202 to obtain the parameter value a 6 , repeatedly obtain multiple parameter values ​​a 6 , and according to multiple parameter values ​​a 6 Calculate the parameter value a n6 .

[0149] In this embodiment, the optical signal detection mode preferably adopts a method of optical signal penetrating clothing to detect the material of clothing. More specifically, the adjacent optical signal detection elements are first controlled to transmit and receive optical signals to obtain the parameter value a. n1 , parameter value a n2 , parameter value a n3 , respectively determine the parameter value a n1 , parameter value a n2 , parameter value a n3 The corresponding clothing material is determined according to the preset target interval of the three parameter values. If the three parameter values ​​are not within the preset target interval, the clothing processing drum is controlled to rotate at a target speed for a target time and then stops rotating, the three parameter values ​​are obtained again, and it is re-determined whether the three parameter values ​​are within the preset target interval. If the three parameter values ​​are within the preset target interval, the corresponding clothing material is temporarily stored, and the relative optical signal detection element is continuously controlled to transmit and receive optical signals to obtain parameter value a. n3 , parameter value a n4 , parameter value a n5 , respectively determine the parameter value a n3 , parameter value an4 , parameter value a n5 Whether it is within the preset target range, and determine the corresponding clothing material according to the preset target range where the three parameter values ​​are located. If the three parameter values ​​are not within the preset target range, control the clothing processing drum to rotate at the target speed for the target time and then stop rotating, re-acquire the three parameter values, and re-judge whether the three parameter values ​​are within the preset target range. If the three parameter values ​​are within the preset target range, determine the corresponding clothing material and temporarily store it. Through the detection method of adjacent and opposite shots between the optical signal detection components, multiple clothing material information is obtained. For example, the detected clothing material information is composed of 3 times cotton and 2 times polyester fiber, then the cotton washing mode can be selected for washing, mainly to protect cotton clothes. If wool material is detected, an alarm can be issued to prompt the user to take out the wool clothes that cannot be washed. Thus, n optical signal detection components form a ring-shaped, cross-shaped optical signal network in the clothing processing drum, and fully cover the clothes in the clothing processing drum in the form of adjacent and opposite shots, and further fully obtain the parameter value a, so that the obtained parameter value a n More accurate, the first light signal detection mode combined with the second light signal detection mode can detect the clothing material more fully and accurately.

[0150] Embodiment 2

[0151] A method for treating clothes is provided, comprising:

[0152] The material detection method in the first embodiment is used to determine the material of the clothing;

[0153] After determining the material of the clothes, enter the sterilization mode.

[0154] The sterilization mode includes using the emitter of the optical signal detection element to emit ultraviolet rays to the clothes in the clothes processing drum, and controlling the clothes processing drum to rotate at a target speed for a target time.

[0155] In this embodiment, the optical signal detection element can be an ultraviolet sensor, the emitter is the ultraviolet sensor emitter, and the receiver is the ultraviolet sensor receiver. When the material of the clothes is determined, the ultraviolet sensor emitter is controlled to emit ultraviolet rays of a suitable sterilization wavelength to sterilize the clothes in the clothing processing drum. At this time, the ultraviolet sensor receiver does not need to work. After the sterilization mode is turned on, the clothing processing drum is controlled to rotate at a target rate and for a target time, each time rotating 120° forward and reverse, at a low speed of 50r / min, for 3 minutes, and the sterilization mode ends. After the sterilization mode ends, the corresponding washing and drying programs can be performed. After the washing and drying programs are performed, the door of the clothing processing equipment is not unlocked, and the ultraviolet sensor emitter can be started again to emit ultraviolet rays to sterilize the clothes in the drum.

[0156] Embodiment 3

[0157] like Figure 3-5 As shown, this embodiment provides a material detection device for identifying the material of clothes in a clothes processing device, including:

[0158] n optical signal detection elements, the optical signal detection element comprising an emitter and a receiver, wherein n≥2;

[0159] n optical signal detection elements are arranged at intervals inside the clothes processing drum 4;

[0160] The n optical signal detectors are configured such that an emitter of any one of the n optical signal detectors emits a first optical signal to the clothes in the clothes processing device, and a receiver of any one of the optical signal detectors receives a second optical signal transmitted through the clothes in the clothes processing device.

[0161] In this embodiment, a light signal is emitted from an emitter in one of the light signal detection components to a receiver in another light signal detection component. The light signal emitted by the emitter passes through the clothes in the clothing processing drum 4, wherein a portion of the light signal is blocked and absorbed by the clothes, while another portion of the light signal penetrates the clothes and is received by the receiver in another detection component. The light signal has different penetrating abilities for clothes of different materials. By utilizing the difference in the penetrating abilities of the light signal for clothes of different materials, the material of the clothes in the clothing processing drum can be determined, and a washing mode matching the material can be selected based on the determined material, thereby achieving targeted protection for clothes of different materials during the washing process.

[0162] N detection elements are arranged at intervals on the inner wall of the clothing processing drum 4, with a simple structure. The emitters in the multiple detection elements can respectively emit light signals to the receiving electrodes in the detection elements other than themselves, thereby forming a ring-shaped, cross-shaped light signal network in the clothing processing drum 4, which fully covers the clothes in the clothing processing drum 4, and can obtain more comprehensive information related to the clothing material, so that the clothing processing drum can detect the clothing material more fully and accurately.

[0163] Wherein, the transmitter and the receiver in the detection element are both powered by the wireless power supply module.

[0164] Optionally, in an implementation of this embodiment,

[0165] Material testing equipment also includes:

[0166] The processor is configured to: control the working states of the emitters and receivers of the n optical signal detection elements, obtain the optical signals received by the receivers in the working state among the n optical signal detection elements, and perform data analysis based on the optical signals.

[0167] The processor can control all of the n optical signal detectors to start / operate, or can control at least two of the n optical signal detectors to operate simultaneously while the other detectors do not operate, or can control one of the emitter and the receiver of a single optical signal detector to operate while the other does not operate. For example, the processor controls the emitter in one of the detectors to emit an optical signal towards the receiver in another detector. The optical signal emitted by the emitter will pass through the clothes in the laundry drum. A part of the optical signal is blocked and absorbed by the clothes, and another part of the optical signal penetrates the clothes and is received by the receiver in another detector. The processor controls the receiver to receive the optical signal emitted by the emitter and converts the optical signal into an electrical signal and feeds it back to the processor. The processor converts the obtained electrical signal into a digital signal and compares it with a preset target range. Each preset target range corresponds to a material, and the processor determines the clothing material based on the preset target range where the digital signal is located.

[0168] Optionally, in an implementation manner of this embodiment, as Figure 3-5 shown,

[0169] In the case of n = 2, the n detectors are arranged as follows:

[0170] The receiver of the second detector is used to receive the optical signal emitted by the emitter of the first detector, and the emitter of the second detector is used to emit an optical signal towards the receiver of the first detector;

[0171] In the case of n ≥ 3, the n detectors are arranged as follows:

[0172] The receiver of the (i + 1)-th detector is used to receive the optical signal emitted by the emitter of the i-th detector, and the emitter of the (i + 1)-th detector is used to emit an optical signal towards the receiver of the (i + 2)-th detector; or, the n detectors are arranged as follows:

[0173] The receiver of the (i + a)-th detector is used to receive the optical signal emitted by the emitter of the i-th detector, and the emitter of the (i + a)-th detector is used to emit an optical signal towards the receiver of the (i + 2a)-th detector;

[0174] wherein, i is a positive integer, and i represents the serial number when the detectors are circularly counted along the circumferential direction of the laundry drum 4. 1 < a < n, and a is a positive integer.

[0175] Among them, circular counting means continuous cumulative counting circle by circle.

[0176] For example, n = 2, as Figure 5As shown, one cycle counting method is 1 (optical signal detection element 1), 2 (optical signal detection element 2), 3 (optical signal detection element 1), 4 (optical signal detection element 2), 5 (optical signal detection element 1), 6 (optical signal detection element 2)...

[0177] like Figure 1 As shown, the receiving electrode of the second optical signal detector (optical signal detector 2) is used to receive the optical signal emitted by the emitting electrode of the first optical signal detector (optical signal detector 1), and the emitting electrode of the second optical signal detector (optical signal detector 2) is used to emit the optical signal to the receiving electrode of the third optical signal detector (optical signal detector 1). Thus, mutual transmission and reception between the emitting electrode 2 and the receiving electrode 3 in the two optical signal detectors are formed.

[0178] For example, when n=3, Figure 3 Or as shown in 4, a cycle counting method is 1 (optical signal detection element 1), 2 (optical signal detection element 2), 3 (optical signal detection element 3), 4 (optical signal detection element 1), 5 (optical signal detection element 2), 6 (optical signal detection element 3)...

[0179] When i=1, the receiving electrode of the second optical signal detector (optical signal detector 2) is used to receive the optical signal emitted by the emitting electrode of the first optical signal detector (optical signal detector 1), and the emitting electrode of the second optical signal detector (optical signal detector 2) is used to emit the optical signal to the receiving electrode of the third optical signal detector (optical signal detector 3), and when i=2, the emitting electrode of the third optical signal detector (optical signal detector 3) is used to emit the optical signal to the receiving electrode of the fourth optical signal detector (optical signal detector 1). Thus, mutual transmission and reception between adjacent emitting electrodes 2 and receiving electrodes 3 in the three optical signal detectors are formed.

[0180] For example, when n=4, a cyclic counting method is 1 (optical signal detection element 1), 2 (optical signal detection element 2), 3 (optical signal detection element 3), 4 (optical signal detection element 4), 5 (optical signal detection element 1), 6 (optical signal detection element 2), 7 (optical signal detection element 3), 8 (optical signal detection element 4)...

[0181] When i=1 and a=2, the receiving electrode of the third optical signal detection element (optical signal detection element 3) is used to receive the optical signal emitted by the emitting electrode of the first optical signal detection element (optical signal detection element 1), and the emitting electrode of the third optical signal detection element (optical signal detection element 3) is used to emit the optical signal to the receiving electrode of the fifth optical signal detection element (optical signal detection element 1);

[0182] When i=2 and a=2, the receiving electrode of the fourth optical signal detector (optical signal detector 4) is used to receive the optical signal emitted by the emitting electrode of the second optical signal detector (optical signal detector 2), and the emitting electrode of the fourth optical signal detector (optical signal detector 4) is used to emit the optical signal to the receiving electrode of the sixth optical signal detector (optical signal detector 2). Thus, mutual transmission and reception between the relative emitting electrodes 2 and receiving electrodes 3 in the four optical signal detectors are formed.

[0183] Among the n optical signal detection components, adjacent emitters and receivers can transmit and receive optical signals to each other, and opposite emitters and receivers can also transmit and receive optical signals to each other, thereby more comprehensively detecting the clothing material in the clothing processing drum 4.

[0184] Optionally, in an implementation of this embodiment, as Figure 3 , 4 Shown

[0185] When n≥3, the n optical signal detection elements are set as follows:

[0186] When n optical signal detection elements work simultaneously, the optical signals emitted by the n optical signal detection elements form an optical signal network distributed in an annular manner along the circumference of the laundry processing tub 4, and / or,

[0187] When n optical signal detection elements work simultaneously, the optical signals emitted by the n optical signal detection elements form an optical signal network that is cross-distributed inside the laundry processing tub 4 .

[0188] In this embodiment, the annularly distributed light signals and the light signals of the cross portions can fully cover the clothes in the clothes processing drum 4, thereby more comprehensively detecting the material of the clothes in the clothes processing drum 4.

[0189] Optionally, in an implementation of this embodiment,

[0190] The emitter of at least one of the n optical signal detection elements has a first emitting element and a second emitting element, the first emitting element faces a first direction and the second emitting element faces a second direction different from the first direction, or the first emitting element and the second emitting element face different receiving electrodes of the optical signal detection element;

[0191] The laundry treatment tub further comprises: a processor for controlling the working states of the first emitting element and the second emitting element in the emitter of at least one optical signal detection element.

[0192] The emitter in the optical signal detection component has a first emitting element and a second emitting element facing different directions, so that the emitter can emit optical signals toward receiving electrodes in different directions, which is convenient for forming transmission and reception between adjacent or relative receiving electrodes and emitters, thereby improving the comprehensive coverage of the detection component for clothing detection in the clothing processing drum 4. According to the detection needs, the processor controls whether the first emitting element and the second emitting element are working.

[0193] Optionally, in an implementation of this embodiment, as Figure 3 , 4 Shown

[0194] In the case of n=3, the laundry treatment drum includes a first optical signal detection element, a second optical signal detection element, and a third optical signal detection element sequentially distributed along the circumferential direction, the first optical signal detection element includes a first emitter 201 and a first receiver 301, the second optical signal detection element includes a second emitter 202 and a second receiver 302, and the third optical signal detection element includes a third emitter 203 and a third receiver 303;

[0195] The three optical signal detection elements are configured as follows: the first emitter 201 can emit an optical signal to the third receiver 303, the third receiver 303 can receive an optical signal emitted from the first emitter 201, the third emitter 203 can emit an optical signal to the second receiver 302, the second receiver 302 can receive an optical signal emitted from the third emitter 203, the second emitter 202 can emit an optical signal to the first receiver 301, the first receiver 301 can receive an optical signal emitted from the second emitter 202, and the first emitter 201 can emit an optical signal to the second receiver 302, the second receiver 302 can receive an optical signal emitted from the first emitter 201.

[0196] First, control the adjacent optical signal detection components to transmit and receive optical signals to obtain parameter value a n1 , parameter value a n2 , parameter value a n3 , respectively determine the parameter value a n1 , parameter value a n2 , parameter value a n3 The corresponding clothing material is determined according to the preset target interval of the three parameter values. If the three parameter values ​​are not within the preset target interval, the clothing processing drum is controlled to rotate at a target speed for a target time and then stops rotating, the three parameter values ​​are obtained again, and it is re-determined whether the three parameter values ​​are within the preset target interval. If the three parameter values ​​are within the preset target interval, the corresponding clothing material is temporarily stored, and the relative optical signal detection element is continuously controlled to transmit and receive optical signals to obtain parameter value a. n3 , parameter value a n4, parameter value a n5 , respectively determine the parameter value a n3 , parameter value a n4 , parameter value a n5 Whether it is within the preset target range, and the corresponding clothing material is determined according to the preset target range of the three parameter values; if the three parameter values ​​are not within the preset target range, the clothing processing drum is controlled to rotate at the target speed for the target time and then stop rotating, the three parameter values ​​are re-obtained, and it is re-determined whether the three parameter values ​​are within the preset target range; if the three parameter values ​​are within the preset target range, the corresponding clothing material is temporarily stored, and multiple clothing material information is obtained through the detection method of adjacent and opposite shots between the optical signal detection components. The first optical signal detection component, the second optical signal detection component and the third optical signal detection component form a ring optical signal network in the clothing processing drum 4, which fully covers the clothes in the clothing processing drum 4, and can obtain more comprehensive information related to clothing materials, so that the clothing processing drum can detect clothing materials more fully and accurately.

[0197] Optionally, in an implementation of this embodiment,

[0198] A first radiating element facing the third receiving electrode 303 and a second radiating element facing the second receiving electrode 302 are disposed in the first radiating electrode 201 .

[0199] That is, by disposing the first emitting element and the second reflecting element, the first emitting electrode 201 can emit an optical signal to the third receiving electrode 303 and can also emit an optical signal to the second receiving electrode 302 .

[0200] Specifically, the second emitter 202 is provided with a third emitting element facing the third direction and a fourth emitting element facing the fourth direction, and the third emitter 203 is provided with a fifth emitting element facing the fifth direction and a sixth emitting element facing the sixth direction;

[0201] The first direction is a direction extending from the first radiating element to the third receiving electrode 303 , and the second direction is a direction extending from the first radiating element to the second receiving electrode 302 ;

[0202] The third direction is a direction extending from the second radiating element to the first receiving electrode 301 , and the fourth direction is a direction extending from the second radiating element to the third receiving electrode 303 ;

[0203] The fifth direction is a direction extending from the third radiating element to the second receiving electrode 302 , and the sixth direction is a direction extending from the third radiating element to the first receiving electrode 301 .

[0204] The above-mentioned emitting element may be a lamp bead.

[0205] In this embodiment, the first emitter 201, the second emitter 202 and the third emitter 203 are all provided with emitting elements facing two different directions, so that when the three optical signal detection components perform detection in the clothing processing drum 4, a ring optical signal network or a cross signal network can be formed, which fully covers the clothing in the clothing processing drum 4, and can obtain more comprehensive information related to the clothing material, so that the clothing processing drum can detect the clothing material more fully and accurately.

[0206] Optionally, in an implementation of this embodiment, as Figure 3-5 As shown,

[0207] n optical signal detection elements are arranged at equal intervals inside the laundry processing tub 4; and / or,

[0208] At least one of the n optical signal detectors is disposed on the lifting rib 1 of the laundry processing tub 4, and an emitting electrode and a receiving electrode of at least one optical signal detector are respectively disposed on two sides of the lifting rib 1 opposite to the inner wall of the laundry processing tub; and / or,

[0209] The emitter and the receiving electrode of the n optical signal detection elements are at the same distance from the bottom of the clothing processing drum 4, or, the emitter of at least one optical signal detection element among the n optical signal detection elements and the receiving electrode for receiving the optical signal emitted by the emitter are at different distances relative to the bottom of the clothing processing drum 4.

[0210] n optical signal detection elements are arranged at equal intervals on the inner wall of the laundry processing tub 4, so that a relatively uniform annular optical signal network or a cross signal network is formed, which more effectively and comprehensively covers the laundry in the laundry processing tub 4;

[0211] When the optical signal detection element is arranged on the lifting rib 1, the wireless power supply module for supplying power to the optical signal detection element is installed on the lifting rib 1, so as to facilitate supplying power to the optical signal detection element;

[0212] When the distances between the emitter and the receiving electrode of n optical signal detection elements and the bottom of the clothing processing drum 4 are the same, the annular signal network or cross signal network formed by the n optical signal detection elements inside the clothing processing drum 4 is in the same vertical plane, and the signal network is relatively uniform. When the distances between the emitter and the receiving electrode for receiving the optical signal emitted by at least one of the n optical signal detection elements and the bottom of the clothing processing drum 4 are different, the annular signal network or cross signal network formed by the n optical signal detection elements inside the clothing processing drum 4 is in different vertical planes, and the signal network has a certain depth in the clothing processing drum. Both of the above situations can fully cover the clothes in the clothing processing drum 4.

[0213] Optionally, in an implementation of this embodiment, as Figure 3-5 As shown,

[0214] The clothes processing tub 4 comprises n lifting ribs 1, which are arranged on the inner wall of the clothes processing tub 4, and the lifting ribs 1 have a first wall surface and a second wall surface which are arranged opposite to each other;

[0215] N optical signal detection elements are respectively arranged on n lifting ribs 1 , and the emitter and the receiver of the optical signal detection element are respectively arranged on the first wall surface and the second wall surface of the lifting rib 1 corresponding to the optical signal detection element.

[0216] The emitter and the receiver in the same optical signal detection element are respectively arranged on the first wall surface and the second wall surface of the corresponding lifting rib 1, which is more convenient for transmission and reception between adjacent detection elements and opposite detection elements.

[0217] The emitter and the receiver installed on both sides of the lifting rib 1 can emit light signals directed to adjacent or opposite receivers.

[0218] Optionally, in an implementation of this embodiment,

[0219] The optical signal detection component is an ultraviolet sensor, the emitter is an ultraviolet sensor emitter, the receiver is an ultraviolet sensor receiver, and the optical signal is an ultraviolet optical signal.

[0220] In this embodiment, the emitter of the ultraviolet sensor emits ultraviolet light with a wavelength range of 100-400nm, and transmits ultraviolet light of 100-400nm to the receiving electrode in another detecting element through the emitter in one of the detecting elements. The ultraviolet light of 100-400nm emitted by the emitter passes through the clothes in the clothing processing drum 4, and a part of the ultraviolet light is blocked and absorbed by the clothes, while the other part of the ultraviolet light of 100-400nm penetrates the clothes and is received by the receiving electrode in another optical signal detecting element. The ultraviolet light of 100-400nm has different penetrating abilities for clothes of different materials. The receiving electrode converts the received ultraviolet rays into electrical signals, which are processed by the MCU chip in the processor and then converted into digital signals. The processor then generates comparable ultraviolet data and compares them with the preset value ranges of various materials. For example, cotton, wool, silk, polyester, linen and other materials all have non-overlapping preset value ranges. By judging the preset target interval where the digital signal is located, the corresponding clothing material can be obtained. According to the judged material, the washing mode that matches the material can be selected, thereby achieving targeted protection for clothes of different materials during the washing process.

[0221] It should be noted that the light signal may be transmitted after contacting the clothing, wherein when the light signal is transmitted after contacting the clothing, a transmission parameter value may be obtained.

[0222] Specifically, the transmission parameter value may be a parameter value of the transmission light signal itself after transmission occurs, such as the transmittance, light intensity, etc. of the transmission light signal, or may be a parameter value obtained after calculating the parameter value of the transmission light signal itself, such as substituting the transmittance and / or light intensity of the transmission light signal into a preset calculation formula to obtain the transmission parameter value. In general, as long as different clothing materials can correspond to different transmission parameter values.

[0223] In an embodiment, the preset calculation formula for calculating the transmission parameter value may be a formula including the wavelength and light intensity of the transmitted light signal, for example, the transmission parameter value b = T% * φ luminous flux * power factor (related to light intensity), and the transmittance T% = I (light intensity after transmission attenuation) / IO (original light intensity) * 100%.

[0224] In the embodiment, in order to determine the material of the clothing, a transmission standard value interval is preset, and different transmission standard value intervals correspond to different clothing materials, that is, there is a corresponding relationship between the transmission standard value intervals and the clothing materials.

[0225] Specifically, the transmission standard value interval is a numerical interval composed of transmission standard values. It should be noted that the transmission standard value and the transmission parameter value are of the same type or are obtained using the same algorithm. The difference is that the transmission standard value is a parameter value obtained by performing a transmission experiment on the clothing when the clothing material is known, while the transmission parameter value is a parameter value obtained by transmitting the clothing when the clothing material is actually identified. For ease of understanding, for example, during the test, the transmittance and light intensity of the transmitted light signal are calculated using formula B to obtain the transmission standard value. After multiple tests on clothing of material b, a numerical interval Q1 can be divided according to all the obtained transmission standard values. When the clothing material is actually identified, the transmittance and light intensity of the transmitted light signal are also calculated using formula B to obtain the transmission parameter value. Since the calculation process of the transmission parameter value is the same as that of the transmission standard value, the clothing material of the clothing can be determined according to the transmission parameter value.

[0226] The corresponding relationship between the transmission standard value interval and the clothing material is: each type of clothing material corresponds to a transmission standard value interval, and different types of clothing materials correspond to different transmission standard value intervals. For example, material a corresponds to the transmission standard value interval Q1, which is the corresponding relationship. When the transmission parameter value is within Q1, it can be determined that the clothing material of the clothing is a. Preferably, the corresponding relationship obtained by testing with an ultraviolet sensor includes: the material tested at 10-13 is cotton, the material tested at 13.5-15.5 is linen, the material corresponding to 19-23 is wool, the material corresponding to 16.5-18.9 is silk, the material corresponding to 29-33 is polyester fiber, and the material corresponding to 33.5-39 is chemical fiber.

[0227] Embodiment 4

[0228] This embodiment provides a material detection method for identifying the material of clothes in a clothes processing device. The material detection method includes:

[0236] In this embodiment, the material detection method uses the first light signal detection mode and the second light signal detection mode, in which the light signals received by the same receiving electrode come from different transmitting electrodes, that is, the clothes in the clothing processing drum are fully covered by adjacent and opposite radiation, so as to further comprehensively obtain parameter values, so that the first parameter values ​​and the second parameter values ​​obtained are more accurate. The combination of the first light signal detection mode and the second light signal detection mode is more comprehensive and accurate for clothing material detection.

[0237] Embodiment 5

[0238] This embodiment provides an electronic device, the electronic device comprising:

[0239] Memory, which stores computer instructions;

[0240] A processor, configured to call and execute computer instructions to implement the material detection method in the first embodiment, or,

[0241] Used to call and execute computer instructions to control the material detection device in the second embodiment and implement the material detection method in the first embodiment.

[0242] The electronic device can control the first emitter to emit a light signal that penetrates clothes to the second receiver along a first direction and is received by the second receiver, obtain a parameter value according to the light signal received by the second receiver, repeatedly obtain multiple parameter values, and calculate the first parameter value according to the multiple parameter values. If the first parameter value is within a target range, the material of the clothes is determined according to the first parameter value and the corresponding relationship between the target range and the material of the clothes, and a first clothing material detection result is obtained, thereby providing accurate and comprehensive data for selecting different washing modes for clothes of different materials, so that clothes of different materials can be detected and protected in a targeted manner.

[0243] Embodiment 6

[0244] like Figure 3 , 4 As shown, this embodiment provides a clothing processing device, which uses the material detection method in Embodiments 1 and 3, or includes the material detection device in Embodiment 2, or includes the electronic device in Embodiment 4.

[0245] The clothing processing device is a washing machine. Three lifting ribs 1 are arranged equidistantly along the axial direction in the clothing processing drum 4 of the washing machine. Each lifting rib 1 is equipped with an optical signal detection component. When the clothing in the clothing processing drum 4 exceeds half load, the optical signal detection component starts to identify the material of the clothing. It first controls the adjacent optical signal detection components to transmit and receive optical signals to obtain parameter value a. n1 , parameter value a n2 , parameter value a n3 , respectively determine the parameter value a n1 , parameter value a n2 , parameter value a n3 The corresponding clothing material is determined according to the preset target interval of the three parameter values. If the three parameter values ​​are not within the preset target interval, the clothing processing drum is controlled to rotate at a target speed for a target time and then stops rotating, the three parameter values ​​are obtained again, and it is re-determined whether the three parameter values ​​are within the preset target interval. If the three parameter values ​​are within the preset target interval, the corresponding clothing material is temporarily stored, and the relative optical signal detection element is continuously controlled to transmit and receive optical signals to obtain parameter value a. n3 , parameter value a n4 , parameter value a n5 , respectively determine the parameter value a n3 , parameter value a n4 , parameter value a n5Whether it is within the preset target range, and determine the corresponding clothing material according to the preset target range where the three parameter values ​​are located. If the three parameter values ​​are not within the preset target range, control the clothing processing drum to rotate at the target speed for the target time and then stop rotating, re-acquire the three parameter values, and re-judge whether the three parameter values ​​are within the preset target range. If the three parameter values ​​are within the preset target range, determine the corresponding clothing material and temporarily store it. Through the detection method of adjacent and opposite shots between the optical signal detection components, multiple clothing material information is obtained. For example, the detected clothing material information is composed of 3 times cotton and 2 times polyester fiber, then the cotton washing mode can be selected for washing, mainly to protect cotton clothes. If wool material is detected, an alarm can be issued to prompt the user to take out the wool clothes that cannot be washed. Thus, n optical signal detection components form a ring-shaped, cross-shaped optical signal network in the clothing processing drum, and fully cover the clothes in the clothing processing drum in the form of adjacent and opposite shots, and further fully obtain the parameter value a, so that the obtained parameter value a n More accurate, the optical signal detection mode adopted is more comprehensive and accurate in detecting clothing materials.

[0246] In summary, the ingenious idea of ​​the clothing material detection method is:

[0247] First, the first emitter is controlled to emit a light signal that penetrates the clothes toward the second receiver along a first direction and is received by the second receiver, a parameter value is obtained according to the light signal received by the second receiver, multiple parameter values ​​are repeatedly obtained, and a first parameter value is calculated according to the multiple parameter values. If the first parameter value is within a target range, the material of the clothes is determined according to the first parameter value and the correspondence between the target range and the material of the clothes, and a first clothing material detection result is obtained, thereby providing accurate and comprehensive data for selecting different washing modes for clothes of different materials, so that clothes of different materials can be detected and protected in a targeted manner.

[0248] Secondly, by first controlling the adjacent optical signal detection components to transmit and receive optical signals to obtain multiple first parameter values, respectively judging whether the multiple first parameter values ​​are within the preset target interval, and determining the corresponding clothing materials according to the preset target intervals where the multiple first parameter values ​​are located, and then controlling the relative optical signal detection components to transmit and receive optical signals to obtain multiple second parameter values, respectively judging whether the multiple second parameter values ​​are within the preset target interval, and obtaining multiple clothing material information through the adjacent and opposite detection methods between the optical signal detection components, n optical signal detection components form a ring-shaped, cross optical signal network in the clothing processing drum, and fully cover the clothing in the clothing processing drum in the adjacent and opposite methods, so that the obtained parameter values ​​are more accurate, and the optical signal detection mode adopted thereby detects clothing materials more fully and accurately.
