In addition, in order to clearly describe the technical scheme of the embodiments of the present application, in the embodiments of the present application, "first", "second" and the like are used to distinguish the same items or similar items with basically the same function and effect. The person skilled in the art can understand that "first", "second" and the like do not limit the number and execution order, and "first", "second" and the like do not necessarily mean different

[0058] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0059] First, the terms related to the embodiments of the present application are introduced.

[0060] Clothes processing device: refers to a device capable of processing loads such as clothes, in which the load can be pants, shoes, hats and other objects with the same processing requirements as clothes, and the embodiments are uniformly replaced by clothes, in which processing includes washing, drying, care, etc. Common clothes processing devices such as washing machines, dryers, clothes care machines, etc.

[0061] Lifting rib: refers to a structure in the processing cylinder for contacting, colliding with, rubbing against, or for changing the distribution of the laundry.

[0062] Laundry treatment equipment is an indispensable device in daily life, which can inject washing, dehydration, drying, care and other treatments to the laundry, greatly improving the convenience of laundry treatment. With the development of technology and the improvement of user demand, the processing accuracy of laundry treatment equipment on laundry has also been improved. Taking a washing machine as an example, the current washing machine usually identifies the material of the laundry before processing the laundry, so that different materials of the laundry can adopt different processing parameters, which helps to improve the processing effect of the laundry.

[0063] However, in actual use, it is found that most detection instruments are limited by their installation positions, which makes it difficult to accurately detect the laundry in the processing cylinder in some cases, thereby reducing the accuracy of the detection result.

[0064] Therefore, the embodiments of the present application provide a lifting rib. Taking the lifting rib applied to the processing cylinder of a laundry treatment equipment as an example, referring to the structure diagram of the lifting rib shown in FIG. 1, the lifting rib comprises a lifting rib body 1 and a support plate 2. Figures 1-8

[0065] The lifting rib body 1 has a convex wall 11 protruding from the inner wall of the processing cylinder to the inside of the processing cylinder, and a mounting space formed by the convex wall 11, the convex wall 11 has a first wall 111 away from the inner wall of the processing cylinder and a second wall 112 extending from the first wall 111 to the inner wall of the processing cylinder.

[0066] The support plate 2 is movably arranged in the mounting space, and the support plate 2 is provided with a detection piece 3 for light signal detection.

[0067] The convex wall 11 has a light-transmitting portion at least at the portion opposite to the detection piece 3 for light signal detection by the detection piece 3.

[0068] The lifting rib body 1 can be one or multiple. The lifting rib body 1 can be arranged at the bottom of the processing cylinder or the inner wall of the processing cylinder. The embodiments do not make specific limitations on this.

[0069] The outer contour of the lifting rib body 1 can be a shape similar to a triangle, quadrilateral or star, and the embodiments do not make specific limitations on this.

[0070] ​In an application scenario, the inner wall of the treatment drum includes a drum bottom and a side wall, the drum bottom is opposite to the opening of the treatment drum, and the side wall is located between the drum bottom and the opening and surrounds a circle. Preferably, if the opening direction of the treatment drum is towards the upper side of the clothes treatment apparatus, the lifting rib body 1 is arranged on the drum bottom of the treatment drum, the lifting rib body 1 extends towards the direction of the opening to form the convex wall 11. If the opening direction of the treatment drum is towards the front side of the clothes treatment apparatus, the lifting rib body 1 is arranged on the side wall of the treatment drum, and the lifting rib body 1 extends towards the upper side of the clothes treatment apparatus to form the convex wall 11.

[0071] For ease of understanding, the extending direction of the lifting rib body 1 forming the convex wall 11 is taken as the height direction of the lifting rib body 1, if the lifting rib body 1 is arranged on the drum bottom, the radial direction of the treatment drum is the length direction of the lifting rib body 1, and the direction perpendicular to the length direction of the lifting rib body 1 in the horizontal plane is the width direction; if the lifting rib body 1 is arranged on the side wall, the direction from the drum bottom to the side wall is the length direction of the lifting rib body 1, and the rotating direction of the treatment drum is the width direction of the lifting rib body 1.

[0072] The convex wall 11 forms an installation space inside, the installation space can be two spaces not communicated with the inside of the treatment drum, or can be a space communicated with the inside of the treatment drum, which is not limited in the embodiment. The support plate 2 is located in the installation space and can move, the support plate 2 can move along the height direction of the lifting rib body 1, or can move along the width direction of the lifting rib body 1, and it needs to be noted that the support plate 2 is movably arranged in the installation space, specifically, the support plate 2 is reciprocally arranged in the installation space. Preferably, the support plate 2 can reciprocally move in the installation space along the height direction of the lifting rib body 1, thereby driving the detection piece 3 to reciprocally move along the height direction of the lifting rib body 1.

[0073] The light transmission part refers to the part on the convex wall 11 that can transmit light, therefore, the light transmission part can be a space without physical structure blocking, such as a through hole, a through slot, etc., or can be a physical structure with light transmission, such as a plate on the convex wall 11 that can transmit light. It needs to be noted that the light transmission part needs to be opposite to the detection piece 3, but since the detection piece 3 can move with the support plate 2, therefore at any position of the moving track of the detection piece 3, there is a light transmission part corresponding to it, so that the detection piece 3 can transmit the light signal to the inside of the treatment drum or receive the light signal from the inside of the treatment drum to the installation space when detecting the light signal.

[0074] By adopting the embodiment, the lifting rib body 1 is provided with the movable support plate 2, and the detection piece 3 is arranged on the support plate 2, so that the position of the detection piece 3 can change with the movement of the support plate 2, thereby improving the detection accuracy of the detection piece 3, which is helpful to improve the accuracy of the detection result of the detection piece 3.

[0075] In a possible embodiment of the present application,

[0076] The second wall 112 is integrally formed with or sealingly connected to the inner wall of the processing cylinder, and the mounting space includes a space formed by the second wall 112 and the first wall 111.

[0077] The extension direction of the first wall 111 is parallel to the width direction or the length direction of the rib body 1, and the extension direction of the second wall 112 is parallel to the height direction of the rib body 1. It should be noted that the parallel in the present embodiment does not require that the two directions are completely parallel, and can also have an included angle, as long as the two directions are not perpendicular.

[0078] Based on the description of the extension directions of the first wall 111 and the second wall 112, it can be known that the second wall 112 is actually a wall enclosing a closed space.

[0079] By adopting the present embodiment, the second wall 112 is integrally formed with or sealingly connected to the processing cylinder, which facilitates the production or connection of the processing cylinder and the rib body 1, and improves the manufacturing convenience or installation convenience of the rib.

[0080] Optionally, in an implementation manner of the present embodiment, the mounting space includes a space formed by the lower cover 12 and the convex wall 11.

[0081] The difference between the present embodiment and the previous embodiment is that the convex wall 11 in the present embodiment has a lower cover 12, and the lower cover 12 is detachably connected to the second wall 112, so that the convex wall 11 and the processing cylinder are two independently produced components. When the rib needs to be arranged in the processing cylinder, the lower cover 12 can be fixedly arranged on the inner wall of the processing cylinder, and then the convex wall 11 is connected to the lower cover 12. The lower cover 12 and the inner wall of the processing cylinder can be welded, integrally formed, or detachably connected; the convex wall 11 and the lower cover 12 can be detachably connected through screws, buckles or other structures.

[0082] By adopting the present embodiment, the mounting mode between the rib body 1 and the processing cylinder becomes flexible by arranging the lower cover 12, and the connection convenience between the rib and the processing cylinder is improved. In addition, the lower cover 12 and the second wall 112 are detachably connected, so that when one of them is damaged, only the damaged part needs to be replaced, without replacing the entire rib body 1, so that the rib body 1 is easy to maintain.

[0083] Optionally, in an implementation manner of the present embodiment, the rib further includes a driving assembly 4, and the driving assembly 4 is arranged in the mounting space.

[0084] The driving assembly 4 is drivingly connected to the support plate 2 to drive the support plate 2 to approach or move away from the light-transmitting part.

[0085] The driving assembly 4 is located in the mounting space and can be fixed in the mounting space by being connected with the lifting rib body 1 or by being connected with the inner wall of the processing cylinder, and the embodiment is not limited in this regard.

[0086] In an application scenario, the light-transmitting part is located on the first wall 111, and the driving assembly 4 is configured to drive the support plate 2 to move along the height direction of the lifting rib body 1, so that the support plate 2 moves to be close to or away from the light-transmitting part.

[0087] According to the embodiment, the driving assembly 4 can drive the support plate 2 to move, thereby improving the convenience and stability of controlling the movement of the support plate 2. The driving assembly 4 is arranged in the mounting space, which is conducive to protecting the driving assembly 4, preventing the driving assembly 4 from being wetted, prolonging the service life of the driving assembly 4, and avoiding the driving assembly 4 from being in contact with the clothes and being entangled.

[0088] Optionally, in an implementation manner of the embodiment, the driving assembly 4 includes a driver 41 and a transmission member 42, an input end of the transmission member 42 is connected with an output shaft of the driver 41, and an output end of the transmission member 42 is connected with the support plate 2.

[0089] The driver 41 has an output shaft, and when the driver 41 is started, the output shaft moves, thereby driving the transmission member 42 connected with the output shaft to move, and the movement of the transmission member 42 drives the support plate 2 to move, thereby achieving the driving effect on the support plate 2.

[0090] The transmission member 42 can change the direction, size and form of the driving force, for example, changing linear motion into rotary motion or changing rotary motion into linear motion.

[0091] According to the embodiment, the driving force of the driver 41 is transmitted to the support plate 2 through the transmission member 42, which can improve the stability of the movement of the support plate 2 and correct the driving force of the driver 41, such as the direction and / or size of the driving force.

[0092] Optionally, in an implementation manner of the embodiment, the driver 41 is an electric motor, and the electric motor is installed in the mounting space through a motor gland 43.

[0093] The transmission member 42 includes a first gear 421, a lead screw 422 and a second gear 423 arranged at one end of the lead screw 422, wherein the first gear 421 is arranged on the output shaft of the electric motor, one end of the lead screw 422 is in transmission connection with the first gear 421 through the second gear 423, and the other end of the lead screw is rotatably connected with the lifting rib body 1.

[0094] One end of the support plate 2 is provided with a threaded hole 21, and the lead screw 422 drives the support plate 2 through the threaded hole 21.

[0095] In an application scenario, the motor is a rotating type motor, that is, after the motor is started, the output shaft of the motor rotates. The first gear 421 rotates with the output shaft and drives the second gear 423 to rotate at the same time. Among them, the size, tooth number and pitch of the first gear 421 and the second gear 423 can be the same or different, and the rotation speed of the second gear 423 is different from that of the first gear 421 at different times, so as to adjust the rotation speed. The lead screw 422 is driven to rotate by the second gear 423, so that the support plate 2 screw connected with the lead screw 422 moves along the height direction of the lead screw 422.

[0096] By adopting the embodiment, the first gear 421, the lead screw 422 and the second gear 423 have high stability, which helps to improve the stability of the movement of the support plate 2. In addition, when the sizes of the first gear 421 and the second gear 423 are different, the movement speed transmitted to the support plate 2 will also be different, which is beneficial to adjust the movement speed of the support plate 2.

[0097] Optionally, in an implementation manner of the embodiment, the support plate 2 is provided with a magnet 22, and a proximity switch 5 is arranged at a position opposite to the magnet 22 in the installation space.

[0098] When the magnet 22 moves to the position corresponding to the proximity switch 5 with the support plate 2, the proximity switch 5 is triggered.

[0099] When the proximity switch 5 is triggered, an electric signal can be generated, and the movement of the support plate 2 can be controlled by the electric signal, so that the proximity switch 5 can be used to automatically control the support plate 2 to stop moving or start moving. Preferably, when the proximity switch 5 is triggered, an electric signal for controlling the support plate 2 to stop moving is generated. Specifically, the electric signal generated by the proximity switch 5 is used to control the motor to brake, so that the support plate 2 stops moving.

[0100] By adopting the embodiment, the control accuracy and convenience of the support plate 2 are improved.

[0101] Optionally, in an implementation manner of the embodiment, a plurality of proximity switches 5 are arranged along the movement direction of the support plate 2.

[0106] The mounting groove 6 is arranged on the first wall 111, and a groove wall is formed on the outer circumferential side in the extension direction of the mounting groove 6, and the groove wall divides the mounting space into the groove space and the containing space.

[0107] It should be noted that in the present embodiment, the mounting groove 6 has a slot opening formed on the first wall 111, and the slot opening is the light transmission part. When the optical signal is transmitted, the optical signal can pass through the slot opening and enter or exit the mounting groove 6.

[0122] The embodiment also provides a clothes treatment device, including at least one lifting rib or at least one treatment drum.

[0123] In the above embodiments of the present application, the description of each embodiment has its own focus, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments. The steps shown in the related flowcharts can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here. In other words, the order of the steps described in the foregoing embodiments is only an example, and reasonable adjustment of the order of the steps based on the content of the embodiments of the present application is also within the protection scope of the embodiments of the present application.

[0124] In a specific implementation of the embodiment of the present application, the laundry treatment device in the above embodiment is a washing machine, the treatment drum is a drum in the washing machine for treating laundry, and the detection member 3 in the lifting rib is an ultraviolet sensor. The structure of the lifting rib arranged in the drum of the washing machine and the use process include:

[0125] The emitter 31 and the receiver 32 of the ultraviolet sensor are installed above the support plate 2, the support plate 2 is provided with a magnet 22 on the side, and the lifting rib wall is provided with a proximity switch 5. The push rod motor is powered and operated by receiving a signal from the main control board, and the support plate 2 is controlled to rise or fall. The lifting rib side wall is respectively provided with three proximity switches 5, as shown in Figures 6-8 The three proximity switches 5 correspond to the distances d1 (10 mm), d2 (15 mm), and d3 (20 mm) of the ultraviolet sensor from the top end of the lifting rib (i.e., the first wall 111), respectively.

[0126] The initial state of the proximity switch 5 and the magnet 22 is off, and when the ultraviolet sensor moves to the distance at which the proximity switch 5 and the magnet 22 are turned on, it proves that the distance d1 (10 mm), d2 (15 mm), or d3 (20 mm) of the ultraviolet sensor from the top end of the lifting rib.

[0127] The whole machine is controlled. After the user puts the clothes into the drum of the washing machine, the driving motor detects the motor current to determine that there is a load in the drum. The main control board sends a signal to the gear motor inside the lifting rib. The support plate 2 of the ultraviolet sensor is raised or lowered by using the lead screw 422, adjusted to the position where the proximity switch 5 and the magnet 22 are turned on, and then combined with the ultraviolet sensor to start detecting and identifying the material of the clothes in the drum to determine whether the current distance is appropriate. If the current distance is not the most appropriate distance, the gear motor continues to drive the ultraviolet sensor, and the proximity switch 5 and the magnet 22 determine the connection. Until the parameters tested by the ultraviolet sensor are the most appropriate parameters, the current distance tested by the ultraviolet sensor is appropriate. After identifying the material of the clothes, the main control board controls the drum to rotate, so that the clothes in the drum are tumbled, and the ultraviolet sensor identifies more clothes. The gear motor starts to act to raise or lower the ultraviolet sensor, so that the ultraviolet sensor is in the best test distance when testing different materials.

[0128] The following structure is described in combination with the parts:

[0129] The lifting rib includes the following components: an upper cover (i.e., a convex wall 11), a lower cover 12, a transparent cover (i.e., a light transmission plate), a DC motor, a gear lead screw 422, a support plate 2, an emitter 31 and a receiver 32 of an ultraviolet sensor, a magnet 22, and a proximity switch 5.

[0130] The following assembly relationship is described:

[0131] The upper cover is matched with a transparent cover which is installed right above the emitter 31 and the receiver 32 of the ultraviolet sensor.

[0132] The lifting rib is internally provided with a direct current motor which is coaxially connected with a gear, and a motor gland 43 is installed below the motor to fix the motor.

[0133] A gear screw rod 422 is installed in front of the direct current motor and cooperates with the gear on the motor.

[0134] A support plate 2 is installed below the gear screw rod 422 and cooperates with the gear screw rod 422.

[0135] The emitter 31 and the receiver 32 of the ultraviolet sensor are installed above the support plate 2 and synchronously move with the support plate 2.

[0136] Magnets 22 are installed on the side edges of the support plate 2 and cooperate with the proximity switches 5 to detect.

[0137] The proximity switches 5 are provided in three groups and are installed in parallel with the distances d1, d2 and d3 on the groove walls of the installation groove 6 in the lifting rib.

[0138] The lower cover 12 is used to fix the internal devices of the lifting rib and is fixed in the inner drum of the washing machine.

[0139] The ultraviolet sensor moves in the lifting rib as follows:

[0140] The main control board supplies power to the direct current motor, the rotor of the direct current motor rotates, the rotor drives the output shaft to rotate, the output shaft drives the gear on the output shaft to rotate, thereby driving the gear of the screw rod 422 to rotate, after the gear of the screw rod 422 rotates, the screw rod 422 also starts to rotate in a certain direction, after the screw rod 422 rotates, the support plate 2 on the screw rod 422 rises or falls according to the direction of the rotation of the screw rod 422, when the screw rod 422 rotates counterclockwise, the support plate 2 on the screw rod 422 starts to rise, when the screw rod 422 rotates clockwise, the support plate 2 on the screw rod 422 starts to fall. While the support plate 2 is rising or falling, the magnets 22 on the side edges of the support plate 2 operate to the positions of the three proximity switches 5, and the corresponding proximity switches 5 are turned on, after observing which of the three proximity switches 5 is turned on, the specific position of the emitter 31 and the receiver 32 of the ultraviolet sensor can be determined, and the distance between the ultraviolet sensor and the first wall 111 can be determined. The uppermost proximity switch 5 corresponds to the distance d1 (10 mm), the middle proximity switch 5 corresponds to the distance d2 (15 mm), and the lowermost proximity switch 5 corresponds to the distance d3 (20 mm). Different test distances are required for testing different materials by the ultraviolet sensor, and the material of the clothes in the drum is detected by the diffuse reflection after the ultraviolet light is turned on.

[0141] The direct current motor has a function of forward and reverse rotation control, which is realized through different wiring methods and circuits. When rotating forward, the corresponding gear on the output shaft rotates clockwise, and when rotating reversely, the corresponding gear on the output shaft rotates counterclockwise. When the gear on the motor rotates clockwise, the gear of the lead screw 422 rotates counterclockwise to realize the lifting of the lifting platform. When the gear on the motor rotates counterclockwise, the gear of the lead screw 422 rotates clockwise to realize the lowering of the lifting platform.

[0142] Next, the method for identifying the material of the clothes by diffuse reflection is illustrated. The clothes material identification method can include the following processing process.

[0143] S100, obtain a plurality of diffuse reflection parameter values in the case of diffuse reflection of the clothes to the incident light signal.

[0144] When identifying the material of the clothes, the incident light signal is emitted to the clothes. After the incident light signal contacts the clothes, it is transmitted through the clothes or diffusely reflected after contacting the clothes. In this embodiment, only the diffuse reflection parameter value generated after diffuse reflection is obtained.

[0145] It should be noted that the diffuse reflection parameter value can be the parameter value of the reflected light signal itself after diffuse reflection, such as the wavelength and light intensity of the reflected light signal. It can also 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 clothes materials can correspond to different diffuse reflection parameter values.

[0146] S102, according to the plurality of diffuse reflection parameter values and the preset correspondence relationship between the clothes material and the diffuse reflection standard value interval, determine the clothes material of the clothes.

[0147] In an embodiment of the present application, the light signal can produce diffuse reflection after contacting the clothes, and then the diffuse reflection parameter value can be obtained.

[0148] Specifically, the diffuse reflection parameter value can be the parameter value of the reflected light signal itself after diffuse reflection, such as the wavelength and light intensity of the reflected light signal. It can also 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 clothes materials can correspond to different diffuse reflection parameter values.

[0149] In an embodiment, the preset calculation formula for calculating the diffuse reflection parameter value can be a formula containing the wavelength and light intensity of the reflected light signal, for example, diffuse reflection parameter value a=(wavelength λ-absorbed wavelength ΔE) / wavelength λ*φ light flux*power factor (light intensity related).

[0150] In an embodiment, in order to determine the material of the clothes, a diffuse reflection standard value interval is preset, and different diffuse reflection standard value intervals correspond to different clothes materials, that is, the diffuse reflection standard value interval has a corresponding relationship with the clothes material.

[0151] 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 values of the same type or obtained by using the same algorithm, and the difference lies in that the diffuse reflection standard value is a parameter value obtained by performing diffuse reflection experiment on the clothes in the case of known clothes material, while the diffuse reflection parameter value is a parameter value obtained by performing diffuse reflection on the clothes in the actual identification of the clothes material. In order to facilitate understanding, for example, in the test, the wavelength and light intensity of the reflected light signal after diffuse reflection are calculated by using formula A to obtain the diffuse reflection standard value. After multiple tests on clothes of material a, a numerical interval P1 can be divided according to all the obtained diffuse reflection standard values. In the actual identification of the clothes material, the wavelength and light intensity of the reflected light signal after diffuse reflection are also calculated by using formula A, that is, the diffuse reflection parameter value is obtained. Since the calculation process of the diffuse reflection parameter value is the same as that of the diffuse reflection standard value, the clothes material of the clothes can be determined according to the diffuse reflection parameter value.

[0152] The corresponding relationship between the diffuse reflection standard value interval and the clothes material is that each type of clothes material corresponds to a diffuse reflection standard value interval, and the diffuse reflection standard value intervals corresponding to different types of clothes materials are different. For example, material a corresponds to the diffuse reflection standard value interval P1, which is the corresponding relationship. When the diffuse reflection parameter value is located in P1, it can be determined that the clothes material of the clothes is a. Preferably, the corresponding relationship obtained by using the ultraviolet sensor for testing and using formula includes: 100-130 test out the material of cotton, 135-155 test out the material of hemp, 190-230 correspond to the material of wool, 165-189 correspond to the material of silk, 290-330 correspond to the material of polyester fiber, and 335-390 correspond to the material of chemical fiber.

[0153] By using the light signal to detect the clothes material, the detection accuracy is not easily affected by water mist, and there is no need for automatic focusing, which helps to improve the identification accuracy of the clothes material. In addition, the clothes are detected by using the diffuse reflection of the incident light signal, and there is no need to penetrate the clothes for detection, so it is not easy to have the defect that the incident light signal cannot penetrate the clothes and cannot be detected, which further ensures the smooth progress of the clothes material identification, and helps to improve the identification accuracy of the clothes material.

[0154] In a possible embodiment of the present application, as shown in Figure 2 the plurality of diffuse reflection parameter values in the case that the clothes diffuse the incident light signal, comprising:

[0155] S200, control the emitter of the light detection piece to emit incident light signals to the clothes covering the light detection piece multiple times.

[0156] The time interval between each emission of the incident light signal can be pre-set, or the total number of emissions of the incident light signal can be pre-set, which is not limited in the embodiment. For example, the incident light signal is emitted 10 times, and each time interval is 10 ms.

[0157] S202, receive the reflected light signal of the clothes diffusely reflecting the incident light signal multiple times through the receiving pole of the light detection piece.

[0158] After each incident light signal is diffusely reflected by the clothes, a reflected light signal is obtained, that is, the incident light signal corresponds to the reflected light signal one by one, so the number of incident light signal emissions is equal to the number of reflected light signals.

[0159] S204, based on the wavelength and / or light intensity of the reflected light signal received multiple times by the receiving pole in the light detection piece, data conversion processing is performed to obtain multiple diffuse reflection parameter values.

[0160] The specific data conversion processing is not limited in the embodiment and can be determined according to actual needs. In order to facilitate understanding, in an application scenario, after the wavelength and light intensity of the reflected light signal are substituted into a pre-set formula, the calculation result is the diffuse reflection parameter value, and the calculation process is the data conversion processing.

[0161] In the embodiment, when the clothes material of the clothes is identified, the incident light signal is emitted multiple times, so that the receiving pole receives the reflected light signal multiple times. Then, multiple diffuse reflection parameter values are converted. On the one hand, compared with one diffuse reflection parameter value, multiple diffuse reflection parameter values are beneficial to avoid special cases and improve the accuracy of the clothes material of the clothes identified based on the diffuse reflection parameter value. On the other hand, the wavelength, light intensity and other information of the reflected light signal are not directly used, but data conversion processing is performed, so that the diffuse reflection standard value interval corresponding to different clothes materials has a large difference, which is beneficial to improve the accuracy of clothes material identification and avoid no identification phenomenon due to small difference between the diffuse reflection standard value intervals corresponding to different clothes materials.

[0162] Optionally, in an implementation manner of the embodiment, the light detection piece is an ultraviolet sensor or an infrared sensor, and the emitter and the receiving pole of the light detection piece are arranged in parallel and tiled under the clothes.

[0163] The parallel tiling means that the emitter and the receiving pole are arranged side by side and tiled under the clothes.

[0164] By adopting the embodiment, the ultraviolet sensor or the infrared sensor is low in cost and is not easy to cause damage to clothes and human bodies. The parallelly tiled emitter and receiver are beneficial to reduce the space occupation of the light detection piece and improve the installation convenience of the light detection piece.

[0165] Optionally, in an implementation manner of the embodiment, as shown in Figure 3 determining the clothes material of the clothes according to the multiple diffuse reflection parameter values and the preset correspondence relationship between the clothes material and the diffuse reflection standard value interval, includes:

[0166] S300, determining a representative value according to the multiple diffuse reflection parameter values.

[0167] The representative value can be a representative value of any aspect or a representative value of any angle. The embodiment does not make a specific limitation thereon, and the actual demand can be determined according to the specific obtaining manner of the diffuse reflection parameter value and / or the specific determination process of the corresponding relationship. For example, in the process of calculating the diffuse reflection parameter value, only a simple algorithm such as addition, subtraction, multiplication and division is used to reflect the wavelength and light intensity of the reflected light signal with a constant, and then the average value of the multiple diffuse reflection parameter values can be used as the representative value when the representative value is determined. For another example, when the corresponding relationship is determined, only the larger value or the maximum value of the diffuse reflection standard value is used, and then the maximum value of the multiple diffuse reflection parameter values is used as the representative value.

[0168] S302, comparing the representative value with each diffuse reflection standard value interval to determine the diffuse reflection standard value interval to which the representative value belongs.

[0169] That is, to determine in which diffuse reflection standard value interval the representative value is located. If the representative value is located in the diffuse reflection standard value interval P1, the representative value belongs to P1. If the representative value is located in P2, the representative value belongs to P2.

[0170] S304, determining the clothes material corresponding to the diffuse reflection standard value interval to which the representative value belongs as the clothes material of the clothes according to the corresponding relationship.

[0171] Since the clothes material has a corresponding relationship with the diffuse reflection standard value interval, that is, the clothes material a corresponds to the diffuse reflection standard value interval P1, the clothes material b corresponds to the diffuse reflection standard value interval P2, the clothes material c corresponds to the diffuse reflection standard value interval P3, and so on. Therefore, after determining the diffuse reflection standard value interval to which the representative value belongs, the clothes material can be determined according to the corresponding relationship, so that the clothes material of the clothes can be determined as the material.

[0172] By adopting the embodiment, the clothes material of the clothes is determined according to the diffuse reflection standard value interval to which the representative value determined according to the multiple diffuse reflection parameter values belongs, which is helpful to improve the accuracy.

[0173] Optionally, in an implementation form of the embodiment, the representative value comprises at least one of a maximum value, a minimum value, a median value, and an average value.

[0174] With the embodiment, whether it is a maximum value, a minimum value, a median value, or an average value, it has certain representativeness in a specific case. The representative value can better reflect the characteristics or features of the plurality of diffuse reflection parameter values, so that the accuracy of the clothes material of the clothes determined according to the representative value is higher.

[0175] Optionally, in an implementation form of the embodiment, the method further comprises:

[0176] After obtaining the plurality of diffuse reflection parameter values, the effectiveness of the plurality of diffuse reflection parameter values is determined according to the stability of the plurality of diffuse reflection parameter values, wherein the effectiveness comprises effective and ineffective;

[0177] If the plurality of diffuse reflection parameter values are effective, the clothes material of the clothes is determined according to the plurality of diffuse reflection parameter values and the preset correspondence between the clothes material and the diffuse reflection standard value interval.

[0178] If the plurality of diffuse reflection parameter values are ineffective, the spatial distribution state of the clothes is changed according to the clothes adjustment strategy, and the plurality of diffuse reflection parameter values in the case that the clothes diffuse the incident light signal are reacquired.

[0179] That is, after obtaining the plurality of diffuse reflection parameter values, the effectiveness thereof is first determined, and the clothes material of the clothes is determined by using the effective plurality of diffuse reflection parameter values.

[0180] The stability refers to the stability of the plurality of diffuse reflection parameter values. When evaluating the stability, the difference between the plurality of diffuse reflection parameter values can be evaluated, or the fluctuation of the plurality of diffuse reflection parameter values can be evaluated, which is not limited in the embodiment.

[0181] For the case that the plurality of diffuse reflection parameter values are ineffective, the spatial distribution state of the clothes is first adjusted, and then the plurality of diffuse reflection parameter values are reacquired. It should be noted that the clothes adjustment strategy is used to change the spatial distribution state of the clothes, and thus the clothes adjustment strategy is not limited in the embodiment. For ease of understanding, for example, the clothes adjustment strategy can be adjusting the position of the clothes, and how to adjust the position can be determined according to actual conditions.

[0182] According to the embodiment, the validity of the plurality of diffuse reflection parameter values is determined, and only when the plurality of diffuse reflection parameter values are valid, the clothing material of the clothes is determined according to the plurality of diffuse reflection parameter values and the corresponding relationship, so as to ensure the accuracy of the determined clothing material. For the invalid plurality of diffuse reflection parameter values, the plurality of diffuse reflection parameter values is reacquired. Since the reacquisition also belongs to the case of acquiring the plurality of diffuse reflection parameter values, the validity is determined again, and so on, so as to realize the cyclic processing and help to improve the accuracy of the determined clothing material.

[0183] Optionally, in an implementation form of the embodiment, the validity of the plurality of diffuse reflection parameter values is determined according to the stability of the plurality of diffuse reflection parameter values, and the determining comprises:

[0184] The validity of the plurality of diffuse reflection parameter values is determined according to the dispersion degree of the plurality of diffuse reflection parameter values, wherein the dispersion degree is used to represent the stability of the plurality of diffuse reflection parameter values.

[0185] According to the embodiment, when the validity of the plurality of diffuse reflection parameter values is determined, the dispersion degree of the plurality of diffuse reflection parameter values is determined, and the calculation process is simple, which helps to reduce the occupation of computing resources.

[0186] Optionally, in an implementation form of the embodiment, the validity of the plurality of diffuse reflection parameter values is determined according to the dispersion degree of the plurality of diffuse reflection parameter values, and the determining comprises:

[0187] The average value of the plurality of diffuse reflection parameter values is calculated.

[0188] The standard deviation representing the dispersion degree is calculated by using the average value and the plurality of diffuse reflection parameter values.

[0189] If the standard deviation exceeds a preset effective threshold, it is determined that the plurality of diffuse reflection parameter values are invalid.

[0190] If the standard deviation does not exceed the effective threshold, it is determined that the plurality of diffuse reflection parameter values are valid.

[0191] The effective threshold can be obtained through experiments, and specifically, when the corresponding relationship is determined, in order to make each diffuse reflection standard value interval not overlap with each other, the standard deviation of the plurality of diffuse reflection parameter values is calculated during the experiment, the formation of the diffuse reflection standard value interval is constrained by the standard deviation, and thus the effective threshold is determined. The specific determination process of the effective threshold is not limited in the embodiment.

[0192] According to the embodiment, the dispersion degree of the plurality of diffuse reflection parameter values is measured by the standard deviation, the calculation process is simple, and the occupation of computing resources is reduced.

[0193] Optionally, in an implementation form of the embodiment, the clothes are located in the clothes treatment drum, and the spatial distribution state of the clothes is changed according to the clothes adjustment strategy, comprising:

[0194] controlling the rotation of the laundry treatment drum by a preset angle.

[0195] It should be noted that the laundry adjustment strategy includes the preset angle, and can also include the rotation direction and the number of rotations of the laundry treatment drum.

[0196] By adopting the embodiment, the control process is simple and fast, and the efficiency of the laundry material identification can be improved.

[0197] Optionally, in an implementation manner of the embodiment, after the rotation of the laundry treatment drum by the preset angle is controlled, the method further includes:

[0198] controlling the rotation of the laundry treatment drum according to preset scattering parameters, so as to reacquire the plurality of diffuse reflection parameter values in the case that the laundry diffusely reflects the incident light signal after the rotation of the laundry treatment drum is stopped.

[0199] The scattering parameters include the rotation speed of the laundry treatment drum and the number of reciprocating rotations. Specifically, in an application scenario, when the rotation of the laundry treatment drum is controlled according to the scattering parameters, the laundry treatment drum is first controlled to rotate forward, and then is controlled to rotate reversely, so as to realize reciprocating rotation. It should be noted that the position of the laundry treatment drum before the rotation according to the scattering parameters is the same as the position after the rotation is stopped.

[0200] By adopting the embodiment, after the scattering parameters are run, the state and the arrangement order of the laundry in the laundry treatment drum are changed, so that the plurality of diffuse reflection parameter values reacquired are not easily the same as or similar to the previously acquired ones, the difference between the plurality of diffuse reflection parameter values acquired previously and the plurality of diffuse reflection parameter values reacquired is improved, and the plurality of diffuse reflection parameter values reacquired are easily determined as valid, thereby reducing the number of times of acquiring the plurality of diffuse reflection parameter values and improving the efficiency of the laundry material identification of the laundry.

[0201] The embodiment further provides a control method of a laundry treatment apparatus, including:

[0202] The laundry material identification method is used to identify the laundry material of the laundry in the laundry treatment drum.

[0203] According to the laundry material of the laundry, the laundry treatment apparatus is controlled to execute corresponding operation parameters.

[0204] The operation parameters can be an operation mode required to be executed by the laundry treatment apparatus, or can be parameters such as an operation time, an operation temperature, and an operation speed of a certain operation mode, and the embodiment does not make a specific limitation on this.

[0205] By adopting the embodiment, the clothes material recognition method is used in the use of the clothes treatment device, and the clothes material of the clothes in the clothes treatment device is recognized. After the clothes material of the clothes is obtained, corresponding operation parameters are executed according to the clothes material of the clothes, so that the clothes treatment device executes different operation parameters for different types of clothes materials when the clothes are processed, and the processing effect of the clothes is improved.

[0206] Optionally, in an implementation manner of the embodiment, the method further includes:

[0207] When the number of times of recognizing the clothes material of the clothes in the clothes treatment drum reaches the preset number of times threshold, the recognition is stopped.

[0208] It should be noted that the clothes material recognition is considered to be performed once for each time of obtaining the plurality of diffuse reflection parameter values. The number of times of recognition is limited by the number of times threshold, so that when the plurality of diffuse reflection parameter values obtained for multiple times are always invalid, the clothes treatment device does not stay in the clothes material recognition stage for a long time.

[0209] By adopting the embodiment, the number of times of recognizing the clothes material is limited by setting the number of times threshold, so that the clothes treatment device does not stay in the clothes material recognition stage for a long time, and the processing efficiency of the clothes treatment device on the clothes is improved.

[0210] In a specific implementation of the embodiment, the light detection member is an ultraviolet sensor, the emitter and the receiver of the ultraviolet sensor are installed in the inside of the lifting rib in a tiled manner, and the distance between the emitter and the receiver of the sensor and the top of the lifting rib (i.e., the clothes placement position) is 10 / 15 / 20 mm or the like. The related working principle is as follows: the ultraviolet emitter emits ultraviolet rays, and the plurality of beams emitted in the horizontal direction contact the measured material. The measured material absorbs ultraviolet rays of different intensities according to the knitting density of different materials. The remaining ultraviolet rays that are not absorbed are reflected back to the receiver after contacting the surface of the material, and the light intensity received by the receiver is the remaining ultraviolet rays that are not absorbed. After the sensor receives the light intensity, the MCU chip of the PCB board processes the electrical signal and converts it into a digital signal. Finally, the measured parameter is obtained, and the control method is used to compare and judge the type of the measured clothes.

[0211] Principle description:

[0212] The wavelength of the ultraviolet spectrum used is 100-400 nm, and the wavelength absorbed is calculated according to quantum theory as DE = hv = hc / , and the wavelength emitted and the wavelength received after diffuse reflection can be calculated by a further data processing algorithm. The following control method needs to use the standard deviation compared with the average value to compare the deviation degree of 10 values compared with the average value, and after the standard deviation is small and the deviation degree is small, the average value obtained is compared with the preset value to obtain the specific interval and determine the material.

[0213] Parameter description:

[0214] △a is the interval range obtained by converting the specific wavelength of the corresponding fixed material through the above formula and then deriving, a is the average value after sampling 10 times, and the standard deviation is the stable value after comparing each value sampled with the average value. Not only △a, but also different materials correspond to different preset value intervals.

[0215] The method includes the following processing process:

[0216] The clothes are put into the drum, and the drive motor of the rear drum starts to weigh, detects the change of the clothes in the drum, and the drive motor current changes, confirming that there are clothes in the drum. The mainboard gives an electrical signal to the ultraviolet sensor inside the lifting rib at this time, and the sensor starts to work and detects the material. Data is captured every 2s, a total of 10 times, 10 data is a group, the average value a of this group is calculated, and the standard deviation corresponding to each data is calculated. Verify the difference between the deviation of the 10 data captured this time and the average value, if the standard deviation and the average value a are large, it means that the deviation range of the 10 data measured from the average value is large, which proves that the detected material may be multiple materials. At this time, it is necessary to adjust the detection angle of the lifting rib 1 sensor, and at this time, it is necessary to drive the motor to adjust the angle. First, rotate the drum by an angle a (60°) in one direction, and rotate back and forth at a low speed of 50r / min, and perform a rocking wash (i.e., run the scattering parameter) to scatter the clothes to a certain extent. The stacking state of the clothes changes within a certain range, and the rotation is stopped after 1 min. The ultraviolet sensor in the lifting rib 1 detects the relationship between the standard deviation and the average value a again. If the standard deviation data is small, the drive motor rotation angle does not need to be controlled, and the average value a is directly compared with the preset interval △a. If the standard deviation data is still large, the drive motor rotation angle β (120°) needs to be driven again, and the inner drum is rotated back and forth at a low speed of 60r / min, and a rocking wash is performed to scatter the clothes to a certain extent.

[0217] The average value a is compared with the closest preset value delta a to determine whether the average value is outside the range or within the range. If the average value is within the range, the corresponding range of the main control board is determined according to the large data preset by the main control board to determine the material. If the average value is outside the range, the reflection angle of the sensor diffuse reflection is deviated. At this time, feedback is given to the main control board. After the main control board receives the feedback problem, the motor is further controlled to rotate the angle alpha. The motor is low-speed forward and reverse rotation to rock the cradle for 1 minute and then stop rotating. The average value a is compared with the preset range delta a again. If the average value is still outside the range, the motor adjustment angle beta is adjusted again.
