Description

Technical Field

[0001] This application relates to the field of processing equipment, and more specifically, to a lifting rib, a processing cylinder, a garment processing device, and a testing method. Background Technology

[0002] Clothing processing equipment is an indispensable part of daily life, capable of performing processes such as washing, spin-drying, drying, and conditioning on clothes, greatly improving the convenience of clothing handling. With technological advancements and increasing user demands, the precision of clothing processing equipment has also improved. Taking washing machines as an example, current washing machines typically perform several detection actions before processing clothes, such as identifying the fabric type, the degree of tangling, and the level of soiling in the water. This allows the washing machine to apply different processing parameters depending on the situation, helping to improve the processing effect.

[0003] Currently, different testing instruments are used for different testing purposes, which increases the testing cost of washing machines. Summary of the Invention

[0004] This application provides a lifting rib, a processing cylinder, a garment processing device, and a testing method to at least solve the technical problem of how to control the testing cost of garment processing equipment.

[0005] According to a first aspect of the embodiments of this application, a lifting rib is provided for being disposed on the processing cylinder of a garment processing device, the lifting rib including a lifting rib body and a rotating platform;

[0006] The lifting rib body has: a convex wall protruding from the inner wall of the processing cylinder toward the interior of the processing cylinder, and an installation space formed by the convex wall, the convex wall having a first wall away from the inner wall of the processing cylinder and a second wall extending from the first wall toward the inner wall of the processing cylinder;

[0007] The rotating platform is rotatably disposed within the installation space. A detection element for optical signal detection is disposed on the rotating platform. The detection element rotates with the rotating platform and emits and / or receives optical signals in different directions at different rotational positions.

[0008] The convex wall has a light-transmitting portion at least in the part opposite to the detection element for the detection element to perform optical signal detection.

[0009] In this embodiment, a rotatable platform is provided within the lifting rib body, and a detection element is mounted on the platform. The position of the detection element changes as the platform rotates. Since the detection element uses optical signals for detection, the direction and path of the optical signal change when the detection element's position changes. This allows the optical signal to contact objects at different locations within the processing cylinder. For example, when identifying clothing material, rotating the detection element allows the optical signal to contact the clothing for material identification; similarly, when conducting water quality testing, the optical signal contacts the water for water quality analysis. By utilizing a rotatable detection element, different detection purposes are achieved, saving on detection costs.

[0010] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the second wall is integrally formed or sealed to the inner wall of the processing cylinder, and the installation space includes the space formed by the second wall and the first wall.

[0011] By adopting this implementation method, the second wall is integrally formed or sealed with the processing cylinder, which facilitates the production or connection of the processing cylinder and the lifting rib body, and improves the manufacturing or installation convenience of the lifting rib.

[0012] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the lifting rib body further includes a lower cover detachably connected to the second wall, and the installation space includes the space formed by the lower cover and the convex wall.

[0013] This implementation method, by setting a lower cover, makes the installation method between the lifting rib body and the processing cylinder more flexible, improving the convenience of connection between the lifting rib and the processing cylinder. Furthermore, the lower cover is detachably connected to the second wall, allowing for replacement of only the damaged part in case of damage to the lifting rib body, without needing to replace the entire lifting rib body, thus facilitating maintenance of the lifting rib body.

[0014] In conjunction with the first aspect, in an optional implementation of this application embodiment, the lifting rib further includes a driving component, which is disposed in the installation space;

[0015] The drive component is connected to the rotary platform drive to drive the rotary platform to rotate.

[0016] Using this implementation, the drive component can drive the rotating platform to rotate, improving the convenience and stability of controlling the rotation of the rotating platform. The drive component is located within the installation space, which helps protect it, making it less susceptible to water ingress and extending its lifespan. It also helps prevent the drive component from coming into contact with clothing and becoming entangled.

[0017] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the driving component includes a first driver, the first driver being fixed in the mounting space, and a first output shaft of the first driver being connected to one end of the rotating platform.

[0018] With this implementation, the first output shaft is connected to one end of the rotary platform, eliminating the need for reducers and other equipment, which helps save on testing costs.

[0019] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the rotating platform is provided in two forms, namely a first platform and a second platform, which are arranged sequentially. The driving component includes a second driver and a transmission component. The second output shaft of the second driver is connected to one end of the first platform. The second platform is driven by the second driver through the transmission component. The two rotating platforms rotate synchronously and in opposite directions.

[0020] In this implementation, the second platform is driven by the second driver through the transmission component. This reduces the number of drivers and saves detection costs. Furthermore, it helps to improve the rotational stability of the second platform by relying on the transmission component.

[0021] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the driver is a motor;

[0022] The transmission component includes a first gear and a second gear;

[0023] The first gear is mounted on the output shaft of the motor, and the second gear meshes with the first gear and is connected to one end of the second platform.

[0024] Using this implementation method, the gear has high stability, which helps to improve the rotational stability of the second platform.

[0025] In conjunction with the first aspect, in an optional implementation of the present application, the convex wall has a mounting groove recessed from the first wall toward the inner wall of the processing cylinder, the mounting groove has an inner space, and one side of the mounting groove has a receiving space formed inside the convex wall, the mounting space including the inner space and the receiving space, the inner space communicating with the receiving space;

[0026] The rotating platform is at least partially located within the slot space and rotates within the slot space so that the detection element can pass through the mounting slot for optical signal detection, and the driving assembly is located within the receiving space.

[0027] This implementation method utilizes a mounting slot, allowing the rotating platform to move within it, facilitating optical signal detection by the detection components on the rotating platform. The drive components within the housing space are less susceptible to interference from outside the housing space, thus improving their operational stability.

[0028] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the mounting groove penetrates the second wall along the width direction of the lifting rib body.

[0029] This implementation method can increase the propagation area of ​​the optical signal and improve the detection accuracy of the detection device.

[0030] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the mounting groove has an opening serving as the light-transmitting portion; or,

[0031] The lifting rib also includes a sealing plate, which is connected to the first wall and the second wall and is used to cover the mounting groove. The sealing plate is a light-transmitting plate that serves as the light-transmitting part.

[0032] This implementation method makes it difficult for clothing or water to enter the containment tank, and thus difficult for it to enter the containment space, protecting the detection components, rotating platform, proximity switch, drive assembly and other parts, and improving their lifespan.

[0033] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the sealing plate includes an extension and a sealing portion, the sealing portion covers part of the mounting groove, the extension covers the unsealed portion of the sealing portion, the extension forms a notch on the sealing plate that communicates with the interior of the treatment cylinder, the extension includes a first plate and a second plate, the first plate and the second plate extend into the mounting groove and are connected within the mounting groove, and a water inlet space communicating with the notch is formed between the first plate and the second plate;

[0034] The first platform and the second platform are located on both sides of the extension, and the first platform and the second platform include rotational positions that are opposite, opposite, and parallel to each other.

[0035] By adopting this implementation method, water or clothing inside the treatment cylinder can enter the water inlet space. When the first platform and the second platform are in a relative rotating position, the detection component can directly detect the water or clothing in the water inlet space, which improves the flexibility and convenience of detection. At the same time, it provides new detection positions and angles for the detection component, enabling it to complete more detection purposes and saving detection costs.

[0036] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the detection element includes the receiving electrode and the transmitting electrode, the receiving electrode being located on the first platform and the transmitting electrode being located on the second platform;

[0037] When the first platform and the second platform are in a relative rotational position, the light signal emitted by the emitting electrode passes through the water inlet space and is received by the receiving electrode;

[0038] When the first platform and the second platform are in opposite rotational positions, the emitter is used to cooperate with other receivers in the processing cylinder for detection, and the receiver is used to cooperate with other emitters in the processing cylinder for detection.

[0039] When the first platform and the second platform are in a parallel rotating position, the light signal from the emitting electrode comes into contact with the clothing inside the processing tube, undergoes diffuse reflection, and is then received by the receiving electrode.

[0040] Using this implementation, the detection device has an emitter and a receiver, and the first platform and the second platform respectively place the emitter and the receiver, so that one detection device can complete multiple detection purposes, saving detection costs.

[0041] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the detection element includes an ultraviolet sensor or an infrared sensor.

[0042] This implementation method is less likely to damage clothing and the human body, and is highly safe.

[0043] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, a magnet is provided on the rotating platform, and at least one proximity switch is provided in the installation space;

[0044] When the magnet rotates with the rotating platform to the position corresponding to the proximity switch, the corresponding proximity switch is triggered.

[0045] Using this implementation method, when the proximity switch is triggered, it can generate an electrical signal. The rotation of the rotating platform can be controlled by the electrical signal, so that the proximity switch can be used to automatically control the rotating platform to stop or start rotating, thereby improving the control accuracy and convenience of the rotating platform.

[0046] According to a second aspect of the embodiments of this application, a processing cylinder of a garment processing device is provided, including at least one of the above-described lifting ribs.

[0047] According to a third aspect of the embodiments of this application, a garment processing device is provided, including at least one of the above-described lifting ribs or at least one of the above-described processing cylinders.

[0048] According to a fourth aspect of the embodiments of this application, a detection method is provided, the detection method comprising:

[0049] Obtain the operational phase of the garment processing equipment;

[0050] The rotating platform is controlled to rotate to the corresponding rotation position according to the described operation phase;

[0051] Control the detection device to perform optical signal detection.

[0052] By adopting this implementation method, the rotating platform can drive the detection piece to rotate, thereby changing the detection angle or detection position of the detection piece. This allows the garment processing equipment at different stages of operation to perform detection for different purposes, thus controlling the detection cost.

[0053] In conjunction with the fourth aspect, in an optional implementation of the embodiments of this application, the rotating platform is provided with two platforms, namely a first platform and a second platform. A sealing plate is provided on the convex wall, and a water inlet space is formed on the sealing plate that communicates with the inside of the processing cylinder but not with the installation space. A receiving electrode of the detection element is provided on the first platform, and an emitting electrode of the detection element is provided on the second platform. The first platform and the second platform are located on both sides of the water inlet space.

[0054] The step of controlling the rotating platform to rotate to the corresponding rotation position according to the operation stage includes:

[0055] If the operation phase is the material identification phase, the first platform and the second platform are controlled to rotate to a position where they are parallel to each other and the emitter and receiver are both facing the inside of the processing cylinder, so as to use diffuse reflection to detect the material of the material inside the processing cylinder.

[0056] If the operation phase is the water quality detection phase, the first platform and the second platform are controlled to rotate to a position where the emitter and receiver are opposite each other, so that the light signal output by the emitter passes through the water inlet space and is received by the receiver, thereby detecting the water quality in the water inlet space.

[0057] This method enables the detection of clothing material using diffuse reflection, and also enables the detection of water quality using opposing refraction when the emitter and receiver are facing each other. This allows the detection device to detect both clothing material and water quality, achieving multiple detection objectives, improving the functionality of the detection device, and saving detection costs.

[0058] In conjunction with the fourth aspect, in an optional implementation of the embodiments of this application, the processing cylinder is provided with at least two of the above-described lifting ribs, the lifting ribs including a first lifting rib and a second lifting rib;

[0059] The step of controlling the rotating platform to rotate to the corresponding rotation position according to the operation stage includes:

[0060] If the operation phase is a multi-target detection phase, then the first lifting rib and the first and second platforms within the second lifting rib are controlled to rotate to opposite positions. When the first and second platforms are opposite each other, the light signal output by the emitter in the first lifting rib enters the processing tank, passes through the clothing and / or water, and is received by the receiver in the second lifting rib to detect the material of the clothing and / or the water quality. The light signal output by the emitter in the second lifting rib enters the processing tank, passes through the clothing and / or water, and is received by the receiver in the first lifting rib to detect the material of the clothing and / or the water quality.

[0061] Using this implementation method, when there are multiple lifting ribs and each of the multiple lifting ribs is equipped with a rotatable rotating platform, the detection elements in the multiple lifting ribs can cooperate with each other by changing the positions of the emitter and receiver, so as to complete the detection of clothing and / or water. The detection methods are diverse and the detection flexibility is improved.

[0062] The technical effects achieved by the second and third aspects mentioned above are similar to those achieved by the corresponding technical means in the first aspect, and will not be repeated here. Attached Figure Description

[0072] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0073] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply differentness.

[0074] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0075] First, the terminology used in the embodiments of this application will be introduced.

[0076] Clothing processing equipment: refers to equipment capable of processing loads such as clothing. In addition to clothing, the load can also be items such as pants, shoes, hats, etc. that have the same processing requirements as clothing. In this embodiment, clothing is used as a substitute. The processing includes washing, drying, and care. Common clothing processing equipment includes washing machines, dryers, and clothing care machines.

[0077] Lifting ribs: These are structures in the processing tube that come into contact with clothing, collide or rub against it, or alter the distribution of the clothing.

[0078] Clothing processing equipment is an indispensable part of daily life, capable of performing processes such as washing, spin-drying, drying, and conditioning on clothes, greatly improving the convenience of clothing handling. With technological advancements and increasing user demands, the precision of clothing processing equipment has also improved. Taking washing machines as an example, current washing machines typically perform several detection actions before processing clothes, such as identifying the fabric type, the degree of tangling, and the level of soiling in the water. This allows the washing machine to apply different processing parameters depending on the situation, helping to improve the processing effect.

[0079] Currently, different testing instruments are used for different testing purposes, which increases the testing cost of washing machines.

[0080] Based on this, this application provides a lifting rib. Taking the application of this lifting rib on the processing drum of a garment processing device as an example, refer to... Figure 1-7 As shown, the lifting rib includes a lifting rib body 1 and a rotating platform 2;

[0081] The lifting rib body 1 has: a convex wall 11 protruding from the inner wall of the processing cylinder toward the interior of the processing cylinder, and an installation 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 toward the inner wall of the processing cylinder.

[0082] The rotating platform 2 is rotatably installed in the installation space. The rotating platform 2 is equipped with a detection element 3 for optical signal detection. The detection element 3 rotates with the rotating platform 2 and emits and / or receives optical signals in different directions at different rotation positions.

[0083] The convex wall 11 has a light-transmitting portion at least in the part opposite to the detection element 3 so that the detection element 3 can perform optical signal detection.

[0084] There can be one or more lifting rib bodies 1. The lifting rib body 1 can be set at the bottom of the processing cylinder or on the side wall of the processing cylinder, and this embodiment does not make specific limitations in this regard.

[0085] The outer contour of the lifting rib body 1 can be a shape similar to a triangle, quadrilateral or star, and this embodiment does not specifically limit it.

[0086] In one application scenario, the inner wall of the processing cylinder includes a bottom and a side wall. The bottom is opposite to the opening of the processing cylinder, and the side wall is located between the bottom and the opening, forming a ring. Preferably, if the opening of the processing cylinder faces upward towards the garment processing equipment, the lifting rib body 1 is disposed at the bottom of the processing cylinder, and the lifting rib body 1 extends in the direction of the opening to form a convex wall 11. If the opening of the processing cylinder faces forward towards the garment processing equipment, the lifting rib body 1 is disposed at the side wall of the processing cylinder, and the lifting rib body 1 extends upward towards the garment processing equipment to form a convex wall 11.

[0087] For ease of understanding, the extension direction of the convex wall 11 formed by the lifting rib body 1 is taken as the height direction of the lifting rib body 1. If the lifting rib body 1 is set at the bottom of the cylinder, the radial direction of the processing cylinder is the length direction of the lifting rib body 1, and the direction of the lifting rib body 1 in the horizontal plane that is perpendicular to its length direction is the width direction. If the lifting rib body 1 is set on the side wall, the direction from the bottom of the cylinder to the side wall is the length direction of the lifting rib body 1, and the rotation direction of the processing cylinder is the width direction of the lifting rib body 1.

[0088] The interior of the convex wall 11 forms an installation space. This installation space and the interior of the processing cylinder can be two separate spaces, or they can be connected; this embodiment does not specifically limit this. The rotating platform 2 is located within the installation space and can rotate. It should be noted that the rotating platform 2 is used to change the detection angle or detection position of the detection element 3. Therefore, the rotation axis of the rotating platform 2 can be a horizontal line or a vertical line, as long as it can change the detection angle or detection position of the detection element 3. Preferably, the rotation axis of the rotating platform 2 is perpendicular to the height direction of the lifting rib body 1.

[0089] The light-transmitting part refers to the portion of the convex wall 11 that allows light to pass through. Therefore, the light-transmitting part can be a space without any solid structure blocking it, such as a through hole or through groove, or it can be a solid structure with light-transmitting properties, such as a light-transmitting plate on the convex wall 11. It should be noted that the light-transmitting part needs to be opposite to the detection element 3. However, since the detection element 3 can rotate with the rotating platform 2, there is a light-transmitting part at any position along the rotation trajectory of the detection element 3. This allows the detection element 3 to use the light-transmitting part to transmit the light signal to the inside of the processing cylinder or receive the light signal transmitted from the inside of the processing cylinder to the installation space when performing light signal detection.

[0090] In this embodiment, a rotatable rotating platform 2 is provided in the lifting rib body 1, and a detection element 3 is provided on the rotating platform 2. The position of the detection element 3 can change as the rotating platform 2 rotates. Since the detection element 3 uses light signals for detection, the propagation direction and path of the light signal also change when the position of the detection element 3 changes. This allows the light signal to come into contact with objects at different positions in the processing cylinder. Thus, when clothing material identification is required, rotating the detection element 3 allows the light signal to come into contact with the clothing for material identification; when water quality testing is required, the light signal comes into contact with the water for water quality testing. By using the rotatable detection element 3, different detection purposes are achieved, saving detection costs.

[0091] In one possible embodiment of this application, the second wall 112 is integrally formed or sealed to the inner wall of the processing cylinder, and the installation space includes the space formed by the second wall 112 and the first wall 111.

[0092] The first wall 111 extends in a direction parallel to the width or length of the lifting rib body 1, and the second wall 112 extends in a direction parallel to the height of the lifting rib body 1. It should be noted that the parallelism described in this embodiment does not require the two directions to be completely parallel; they can also have an angle, as long as the two directions are not perpendicular.

[0093] Based on the description of the extension direction of the first wall 111 and the second wall 112, it can be seen that the second wall 112 is actually a wall that encloses a closed space.

[0094] In this embodiment, the second wall 112 is integrally formed or sealed with the processing cylinder, which facilitates the production or connection of the processing cylinder and the lifting rib body 1, and improves the manufacturing or installation convenience of the lifting rib.

[0095] Optionally, in one implementation of this embodiment, the lifting rib body 1 further includes a lower cover 12 detachably connected to the second wall 112, and the installation space includes the space formed by the lower cover 12 and the protruding wall 11.

[0096] Unlike the previous embodiment, the convex wall 11 in this embodiment has a lower cover 12, which is detachably connected to the second wall 112. This makes the convex wall 11 and the processing cylinder two independently manufactured components. When lifting ribs need to be installed inside the processing cylinder, the lower cover 12 can be fixed to the inner wall of the processing cylinder first, and then the convex wall 11 and the lower cover 12 can be connected. 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 by screws, clips, or other structures.

[0097] In this embodiment, the installation method between the lifting rib body 1 and the processing cylinder is made more flexible by setting the lower cover 12, which improves the convenience of connection between the lifting rib and the processing cylinder. In addition, the lower cover 12 and the second wall 112 are detachably connected, which makes it easy to replace only the damaged part when one of them is damaged, without replacing the entire lifting rib body 1, making the lifting rib body 1 easy to maintain.

[0098] Optionally, in one implementation of this embodiment, the lifting rib further includes a driving component 4, which is disposed in the installation space;

[0099] The drive component 4 is connected to the rotary platform 2 to drive the rotary platform 2 to rotate.

[0100] Among them, the driving component 4 refers to a component with driving capability. The driving component 4 is located in the installation space. It can be fixed in the installation space by connecting with the lifting rib body 1, or it can be fixed in the installation space by connecting with the inner wall of the processing cylinder. This embodiment does not make specific limitations on this.

[0101] In this embodiment, the drive assembly 4 can drive the rotating platform 2 to rotate, improving the convenience and stability of controlling the rotation of the rotating platform 2. The drive assembly 4 is located within the installation space, which helps protect it, making it less susceptible to water ingress and extending its lifespan. It also helps prevent the drive assembly 4 from contacting clothing and becoming entangled.

[0102] Optionally, in one implementation of this embodiment, the drive component 4 includes a first driver, which is fixed in the installation space, and the first output shaft of the first driver is connected to one end of the rotating platform 2.

[0103] With this implementation, the first output shaft is connected to one end of the rotary platform 2, eliminating the need for reducers and other equipment, which helps save on testing costs.

[0104] Optionally, in one implementation of this embodiment, there are two rotating platforms 2, namely a first platform 21 and a second platform 22. The two rotating platforms 2 are arranged in sequence and parallel to each other. The driving component 4 includes a second driver 41 and a transmission component 42. The second output shaft of the second driver 41 is connected to one end of the first platform 21. The second platform 22 is driven by the second driver 41 through the transmission component 42. The two rotating platforms 2 rotate synchronously and in opposite directions.

[0105] The transmission component 42 has functions including, but not limited to, changing the direction, magnitude, and form of the driving force. Specifically, the driving form may be, for example, changing linear motion into rotational motion.

[0106] In this embodiment, the second platform 22 is driven by the second driver 41 via the transmission component 42. This reduces the number of drivers and saves detection costs. On the other hand, it helps to improve the rotational stability of the second platform 22 by relying on the transmission component 42.

[0107] Optionally, in one implementation of this embodiment, the driver is a motor;

[0108] The transmission component 42 includes a first gear 421 and a second gear 422;

[0109] The first gear 421 is mounted on the output shaft of the motor, and the second gear 422 meshes with the first gear 421 and is connected to one end of the second platform 22.

[0110] In one application scenario, the motor is a rotary motor, meaning that after the motor starts, its output shaft rotates. The first gear 421 follows the output shaft in its rotational motion and simultaneously drives the second gear 422 to rotate. Preferably, the first gear 421 and the second gear 422 are identical, such that the second platform 22 and the first platform 21 rotate in opposite directions but at the same speed.

[0111] In this embodiment, the gears have high stability, which helps to improve the rotational stability of the second platform 22.

[0112] Optionally, in one implementation of this embodiment, the convex wall 11 has a mounting groove 6 recessed from the first wall 111 toward the inner wall of the processing cylinder. The mounting groove 6 has an inner space, and one side of the mounting groove 6 has a receiving space formed inside the convex wall 11. The mounting space includes the inner space and the receiving space, and the inner space and the receiving space are in communication.

[0113] The rotating platform 2 is located at least partially within the slot space and rotates within the slot space so that the detection element 3 can pass through the mounting slot 6 for optical signal detection, and the drive assembly 4 is located within the receiving space.

[0114] An installation groove 6 is opened on the first wall 111, and a groove wall is formed on the outer periphery of the extension direction of the installation groove 6. The groove wall divides the installation space into the groove space and the receiving space.

[0115] It should be noted that, in this embodiment, a slot 6 is formed on the first wall 111, which is a light-transmitting part. This allows the light signal to pass through the slot and enter or leave the space inside the slot during transmission.

[0116] In this embodiment, by creating the mounting slot 6, the rotating platform 2 can move within the mounting slot 6, facilitating optical signal detection by the detection element 3 on the rotating platform 2. The drive component 4 within the accommodating space is less susceptible to interference from outside the accommodating space, thus improving the operational stability of the drive component 4.

[0117] Optionally, in one implementation of this embodiment, the mounting groove 6 penetrates the second wall 112 along the width direction of the lifting rib body 1.

[0118] By using this embodiment, the propagation area of ​​the optical signal can be increased, and the detection accuracy of the detection component 3 can be improved.

[0119] Optionally, in one implementation of this embodiment, the mounting groove 6 has an opening that serves as a light-transmitting portion; or,

[0120] The lifting rib also includes a sealing plate 7, which is connected to the first wall 111 and the second wall 112 and is used to seal the mounting groove 6. The sealing plate 7 is a light-transmitting plate that serves as a light-transmitting part.

[0121] Among them, the sealing plate 7 is detachably connected to the lifting rib body 1.

[0122] This embodiment makes it difficult for clothing or water to enter the receiving tank, and thus difficult for it to enter the receiving space, protecting the detection component 3, rotating platform 2, proximity switch, drive assembly 4 and other parts, and improving their lifespan.

[0123] Optionally, in one implementation of this embodiment, the sealing plate 7 includes an extension 71 and a sealing portion 72. The sealing portion 72 covers part of the mounting groove 6, and the extension 71 covers the unsealed portion of the sealing portion 72. The extension 71 forms a notch 723 on the sealing plate 7 that communicates with the inside of the treatment cylinder. The extension 71 includes a first plate 721 and a second plate 722. The first plate 721 and the second plate 722 extend into the mounting groove 6 and are connected within the mounting groove 6. A water inlet space 724 communicating with the notch 723 is formed between the first plate 721 and the second plate 722.

[0124] The first platform 21 and the second platform 22 are located on both sides of the extension 71, and the first platform 21 and the second platform 22 include rotational positions that are opposite, opposite, and parallel to each other.

[0125] For ease of understanding, the cross-section of the extension 71 is approximately V-shaped or an inverted "V" shape, such that the extension 71 includes a notch 723, and the notch 723 is located at the junction of the extension 71 and the sealing groove 72. After the extension 71 extends into the mounting groove 6, the first plate 721 and the second plate 722 are connected, making the sealing groove plate 7 a continuous and uninterrupted plate. Preferably, the extension 71 and the sealing groove 72 are integrally formed.

[0126] Because the extension 71 divides the space into an inlet space 724, it divides the tank space into two parts that are either connected or not connected. The first platform 21 is located in one part, and the second platform 22 is located in the other part. That is, the first platform 21 is located on the left side of the extension 71, and the second platform 22 is located on the right side of the extension 71. It should be noted that the left and right sides are only for ease of understanding and do not limit the direction.

[0127] In this embodiment, water or clothing inside the treatment cylinder can enter the water inlet space 724. When the first platform 21 and the second platform 22 are in a relative rotating position, the detection element 3 can directly detect the water or clothing in the water inlet space 724, which improves the flexibility and convenience of detection. At the same time, it provides the detection element 3 with a new detection position and detection angle, enabling the detection element 3 to complete more detection purposes and save detection costs.

[0128] Optionally, in one implementation of this embodiment, the detection element 3 includes a receiving electrode 32 and a transmitting electrode 31, with the receiving electrode 32 located on the first platform 21 and the transmitting electrode 31 located on the second platform 22;

[0129] When the first platform 21 and the second platform 22 are in a relative rotating position, the light signal emitted by the emitter 31 passes through the water inlet space 724 and is received by the receiver 32.

[0130] When the first platform 21 and the second platform 22 are in opposite rotational positions, the emitter 31 is used to cooperate with other receivers 32 in the processing cylinder for detection, and the receiver 32 is used to cooperate with other emitters 31 in the processing cylinder for detection.

[0131] When the first platform 21 and the second platform 22 are in a parallel rotating position, the light signal from the emitter 31 is diffusely reflected after contacting the clothing inside the processing tube and is received by the receiver 32.

[0132] Preferably, both the first platform 21 and the second platform 22 are horizontally arranged, with their rotation axes being parallel horizontal lines. The emitting electrode 31 has an output end for optical signals, and the receiving electrode 32 has a receiving end for optical signals. When the first platform 21 and the second platform 22 are opposite to each other, the output end of the emitting electrode 31 is opposite to the receiving end of the receiving electrode 32. When the first platform 21 and the second platform 22 are opposite to each other, the output end of the emitting electrode 31 is opposite to the receiving end of the receiving electrode 32. When the first platform 21 and the second platform 22 are parallel, the output end of the emitting electrode 31 and the receiving end of the receiving electrode 32 are also parallel in orientation. Preferably, when the first platform 21 and the second platform 22 are parallel, the output end of the emitting electrode 31 and the receiving end of the receiving electrode 32 both face upwards towards the clothing processing device.

[0133] It should be noted that when the output end of the emitter 31 is opposite to the receiving end of the receiver 32, the light signal can pass through the water or clothing in the water inlet space 724, be refracted, and then be received by the receiver 32; when the output end of the emitter 31 is parallel to the receiving end of the receiver 32, the light signal can pass through the sealing plate 7, come into contact with the clothing, undergo diffuse reflection, and then be received by the receiver 32; when the output end of the emitter 31 is opposite to the receiving end of the receiver 32, the receiver 32 cannot receive the light signal emitted by the emitter 31 in the same lifting rib, but the receiver 32 can receive the light signal emitted by the emitter 31 in other lifting ribs after transmission.

[0134] Using this implementation, the detection element 3 has an emitter 31 and a receiver 32, and the first platform 21 and the second platform 22 respectively place the emitter 31 and the receiver 32, so that one detection element 3 can complete multiple detection purposes, saving detection costs.

[0135] Optionally, in one implementation of this embodiment, the detection element 3 includes an ultraviolet sensor or an infrared sensor.

[0136] This implementation method is less likely to damage clothing and the human body, and is highly safe.

[0137] Optionally, in one implementation of this embodiment, a magnet 23 is provided on the rotating platform 2, and at least one proximity switch is provided in the installation space;

[0138] When magnet 23 rotates with rotating platform 2 to the position corresponding to the proximity switch, the corresponding proximity switch is triggered.

[0139] Preferably, there are three proximity switches. When the first platform 21 is opposite to the second platform 22, the magnet 23 triggers the first proximity switch. When the first platform 21 is parallel to the second platform 22, the magnet 23 triggers the second proximity switch. When the first platform 21 is opposite to the second platform 22, the magnet 23 triggers the third proximity switch.

[0140] With this implementation, when the proximity switch is triggered, it generates an electrical signal, which can be used to control the rotation of the rotating platform 2. This allows the proximity switch to automatically control the rotating platform 2 to stop or start rotating, improving the control accuracy and convenience of the rotating platform 2.

[0141] This embodiment also provides a processing cylinder for a garment processing device, including at least one of the above-described lifting ribs.

[0142] This embodiment also provides a garment processing device, including at least one of the above-described lifting ribs or at least one of the above-described processing cylinders.

[0143] This embodiment also provides a detection method, which is applied to the aforementioned lifting ribs, processing cylinders, or clothing processing equipment, such as... Figure 8 As shown, the detection methods include:

[0144] S100, Obtain the operation phase of the garment processing equipment.

[0145] The garment processing equipment operates through different stages, such as a weighing stage, a water intake stage, and a heating stage. This embodiment does not specifically limit these stages. Different stages may have different testing objectives. For example, before the water intake stage, the fabric material of the garment needs to be tested to determine the appropriate water intake. Similarly, during the washing stage, water quality needs to be tested to determine the level of dirt in the washing water, thus deciding whether to extend the washing time or increase the number of washes.

[0146] S102. Control the rotating platform 2 to rotate to the corresponding rotation position according to the operation stage.

[0147] Since different operating phases correspond to different detection objectives, the rotating platform 2 is rotated to the corresponding rotation position according to the detection objective required for each operating phase. Preferably, the rotation positions include positions where the emitter 31 and receiver 32 are opposite each other, positions where the emitter 31 and receiver 32 face the same direction, and positions where the emitter 31 and receiver 32 are opposite each other.

[0148] Specifically, when the emitter 31 and receiver 32 are facing each other, the principle of light refraction can be used to detect water quality; when the emitter 31 and receiver 32 are oriented in the same direction, the principle of light diffuse reflection can be used to detect the material of clothing; when the emitter 31 and receiver 32 are facing away from each other, the principle of light transmission can be used to detect the material of clothing or water quality. This embodiment does not specifically limit the specific detection process.

[0149] S104, control the detection component 3 to perform optical signal detection.

[0150] Using this implementation, the rotating platform 2 can drive the detection piece 3 to rotate, thereby changing the detection angle or detection position of the detection piece 3. This allows the garment processing equipment at different stages of operation to perform detection for different purposes, thus controlling detection costs.

[0151] Optionally, in one implementation of this embodiment, the rotating platform 2 is provided with two platforms, namely a first platform 21 and a second platform 22. A sealing plate 7 is provided on the convex wall 11. A water inlet space 724 is formed on the sealing plate 7, which is connected to the inside of the processing cylinder but not connected to the installation space. A receiving electrode 32 of the detection element 3 is provided on the first platform 21, and an emitting electrode 31 of the detection element 3 is provided on the second platform 22. The first platform 21 and the second platform 22 are located on both sides of the water inlet space 724.

[0152] According to the operation phase, the rotating platform 2 is controlled to rotate to the corresponding rotation position, including:

[0153] If the operation phase is the material recognition phase, the first platform 21 and the second platform 22 are controlled to rotate to a position where they are parallel to each other and the emitter 31 and receiver 32 are both facing the inside of the processing cylinder, so as to use diffuse reflection to detect the material of the material inside the processing cylinder.

[0154] If the operation phase is the water quality detection phase, the first platform 21 and the second platform 22 are controlled to rotate to opposite positions and the emitter 31 and receiver 32 are opposite each other, so that the light signal output by the emitter 31 passes through the water inlet space 724 and is received by the receiver 32, and the water quality in the water inlet space 724 is detected.

[0155] By adopting this implementation method, the material of clothing can be detected by diffuse reflection, and the water quality can be detected by opposing refraction when the emitter 31 and receiver 32 are facing each other. This allows the detection element 3 to detect both clothing material and water quality, achieving multiple detection purposes, improving the functionality of the detection element 3, and saving detection costs.

[0156] Optionally, in one implementation of this embodiment, at least two of the above-mentioned lifting ribs are provided on the processing cylinder, and the lifting ribs include a first lifting rib and a second lifting rib;

[0157] According to the operation phase, the rotating platform 2 is controlled to rotate to the corresponding rotation position, including:

[0158] If the operation phase is a multi-target detection phase, the first lifting rib and the first platform 21 and the second platform 22 within the second lifting rib are controlled to rotate to opposite positions. When the first platform 21 and the second platform 22 are opposite, the light signal output by the emitter 31 within the first lifting rib enters the processing tank, passes through the clothing and / or water, and is received by the receiver 32 within the second lifting rib to detect the material of the clothing and / or the water quality. The light signal output by the emitter 31 within the second lifting rib enters the processing tank, passes through the clothing and / or water, and is received by the receiver 32 within the first lifting rib to detect the material of the clothing and / or the water quality.

[0159] With this implementation, when there are multiple lifting ribs and each of the multiple lifting ribs is equipped with a rotatable rotating platform 2, the detection elements 3 in the multiple lifting ribs can cooperate with each other by changing the positions of the emitter 31 and the receiver 32 to complete the detection of clothing and / or water. The detection methods are diverse, which improves the flexibility of detection.

[0160] In the above embodiments of this application, the descriptions of each embodiment have their own emphasis. Parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments. The steps illustrated in the related flowcharts can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown here. In other words, the order of steps described in the foregoing embodiments is merely an example. Reasonable adjustments to the order of steps based on the content of the embodiments of this application are also within the protection scope of the embodiments of this application.

[0161] In one specific implementation of the embodiments of this application, the clothing processing device in the above embodiments is a washing machine, the processing drum is the drum in the washing machine used for processing clothing, and the detection element in the lifting rib is an ultraviolet sensor. The structure and usage process of the lifting rib disposed in the washing machine drum include:

[0162] The ultraviolet sensor includes an emitter and a receiver. The lifting rib has the following components: a sealing plate, a proximity switch, a raised wall, a motor, a rotating platform, and a lower cover.

[0163] Assembly relationship description:

[0164] The sealing plate has a water inlet space in the middle. Its main function is to detect clothing in the water inlet space when the emitter and receiver are compared inside the lifting ribs. The sealing plate also serves to prevent water, dust, and pollution.

[0165] The proximity switch is used to detect the rotational state of the sensor inside the lifting rib.

[0166] The raised wall serves to protect and waterproof the internal components of the lifting rib.

[0167] The motor is a DC motor with a rotor that rotates with gears. The gears have a rotating platform that drives the emitter and receiver to change their angles.

[0168] The rotating platform has a gear at its end, which works with the motor shaft rotor to rotate. The rotating platform has two inside the lifting ribs, one to support the emitter and the other to support the receiver.

[0169] The emitter emits ultraviolet (100-400nm) or near-infrared (700-2500nm) light.

[0170] The light emitted by the receiver and emitter passes through the clothing being tested (in a flat state) or particulate foreign objects (in a state of opposing installation) and is received by the receiver.

[0171] The lower cover serves to fix the lifting ribs within the inner cylinder.

[0172] Control methods:

[0173] The lifting ribs have a sealing plate, which is not flat and has an internal water inlet space. The sealing plate is an acrylic cover with high light transmittance and good waterproof performance. The emitter and receiver of the internal sensor are initially laid flat. The flat position uses the principle of diffuse reflection to identify the material of the clothing. After detecting the material, the water quality or particulate matter in the water needs to be detected.

[0174] In the first scenario, with the emitter and receiver facing each other, a sensor on a lifting rib can be used to detect water quality and particulate matter in the washing water. For water quality and foreign matter detection, the emitter and receiver need to be aligned. This requires driving a DC motor to rotate. The rotating motor's rotor drives a rotating shaft, which in turn drives a gear on the shaft. This is the first stage of transmission. The first stage of transmission drives the rotating platform to rotate. When the gear rotates counterclockwise, it rotates the receiver 90° counterclockwise, so the receiver faces the inside of the lifting rib, i.e., the sealing plate. Simultaneously, the corresponding gear on the receiver rotates counterclockwise, driving the gear on the rotating platform of the emitter to rotate 90° clockwise, forming the second stage of transmission. After rotation, the emitter also faces the sealing plate, directly opposite the receiver. The emitter and receiver are now in a relative position, ultimately allowing for the detection of foreign matter and water quality within the water inlet space of the sealing plate.

[0175] In the second scenario, based on the first scenario where the emitter and receiver are opposite each other, diffuse reflection is again generated by a motor drive to identify the material of the clothing inside the drum, aligning the emitter and receiver in a flat position. The motor shaft rotates clockwise, causing the rotating platform and receiver to rotate clockwise, forming a primary transmission. The receiver rotates 90° clockwise, moving it from its original sideways angle to a flat position. Because the gears on the emitter and receiver rotating platforms rotate in tandem, as the receiver rotates 90° clockwise, the gears on the emitter's rotating platform are driven by the receiver's gears, forming a secondary transmission, rotating it 90° counterclockwise, thus aligning the emitter in a flat position. At this point, the emitter and receiver are flat, emitting light upon power-up. This light is diffusely reflected upon contact with the clothing, allowing for clothing detection. The receiver receives the remaining light intensity after some of the light intensity has been absorbed by the clothing.

[0176] In the third scenario, based on the second scenario where the emitter and receiver are laid flat, a DC motor directs the emitter and receiver outwards towards both sides of the lifting rib. The receiver on the other lifting rib also faces outwards. After one emitter emits light, the receiver on the other lifting rib receives it, allowing for the detection of both water quality and clothing through transmission and refraction. Initially, the emitter and receiver are laid flat. The receiver is then rotated 90° clockwise. After powering on the DC motor, the rotor drives the shaft to rotate clockwise, causing the rotating platform and receiver to rotate 90° clockwise. The gears on the emitter's rotating platform are then driven to rotate counter-clockwise by a secondary transmission mechanism, resulting in both the emitter and receiver facing both sides of the lifting rib.

[0177] The side wall of the lifting rib has three proximity switches. Both the emitter and receiver ends have magnets. Rotating to different positions corresponds to the activation of different proximity switches, which detect and determine the rotation angle of the corresponding emitter and receiver.

[0178] The following example illustrates a method for identifying clothing material using diffuse reflection. The clothing material identification method may include the following processing steps.

[0179] S100: Obtain multiple diffuse reflection parameter values ​​when the clothing diffusely reflects the incident light signal.

[0180] When identifying the material of clothing, an incident light signal is emitted towards the clothing. After the incident light signal comes into contact with the clothing, it either passes through the clothing and is transmitted, or it undergoes diffuse reflection after contact with the clothing. This embodiment only obtains the diffuse reflection parameter value generated after diffuse reflection occurs.

[0181] 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 intensity of the reflected light signal, or it can be a parameter value obtained by calculating the parameters of the reflected light signal itself, such as substituting the wavelength and / or intensity of the reflected light signal into a preset calculation formula to obtain the diffuse reflection parameter value. In general, it is sufficient as long as different clothing materials correspond to different diffuse reflection parameter values.

[0182] S102. Determine the fabric material of the garment based on multiple diffuse reflection parameter values ​​and the preset correspondence between the fabric material and the diffuse reflection standard value range.

[0183] In one embodiment of this application, the light signal can generate diffuse reflection after coming into contact with clothing, thereby obtaining the diffuse reflection parameter value.

[0184] 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 intensity of the reflected light signal, or it can be a parameter value obtained by calculating the parameter value of the reflected light signal itself, such as substituting the wavelength and / or intensity of the reflected light signal into a preset calculation formula to obtain the diffuse reflection parameter value. In general, it is sufficient as long as different clothing materials correspond to different diffuse reflection parameter values.

[0185] In one embodiment, the preset calculation formula for calculating the diffuse reflection parameter value can be a formula that includes the wavelength and intensity of the reflected light signal. For example, the diffuse reflection parameter value a = (wavelength λ - absorbed wavelength ΔE) / wavelength λ * φ luminous flux * power factor (intensity related).

[0186] In one embodiment, in order to determine the material of the clothing, a standard range of diffuse reflection values ​​is preset. Different standard ranges of diffuse reflection values ​​correspond to different clothing materials. In other words, there is a correspondence between the standard range of diffuse reflection values ​​and the clothing material.

[0187] Specifically, the diffuse reflectance standard value range is a numerical range composed of diffuse reflectance standard values. It's important to note that diffuse reflectance standard values ​​and diffuse reflectance parameter values ​​are of the same type or obtained using the same algorithm. The difference lies in that diffuse reflectance standard values ​​are parameter values ​​obtained by conducting diffuse reflectance experiments on clothing with known material characteristics, while diffuse reflectance parameter values ​​are parameter values ​​obtained by conducting diffuse reflectance experiments on clothing during actual material identification. For ease of understanding, for example, during testing, formula A is used to calculate the wavelength and intensity of the reflected light signal after diffuse reflection to obtain the diffuse reflectance standard value. After multiple tests on clothing of material 'a', a numerical range P1 can be defined based on all the obtained diffuse reflectance standard values. In actual clothing material identification, formula A is also used to calculate the wavelength and intensity of the reflected light signal after diffuse reflection, thus obtaining the diffuse reflectance parameter value. Since the calculation process for the diffuse reflectance parameter value is the same as that for the diffuse reflectance standard value, the clothing material can be determined based on the diffuse reflectance parameter value.

[0188] The correspondence between diffuse reflectance standard value ranges and clothing materials is as follows: each type of clothing material corresponds to a diffuse reflectance standard value range, and different types of clothing materials correspond to different diffuse reflectance standard value ranges. For example, material 'a' corresponds to diffuse reflectance standard value range P1, which is the correspondence. This ensures that when the diffuse reflectance parameter value is within P1, the clothing material can be determined to be 'a'. Preferably, the correspondence obtained using an ultraviolet sensor and the formula includes: 100-130 corresponds to cotton, 135-155 to linen, 190-230 to wool, 165-189 to silk, 290-330 to polyester fiber, and 335-390 to synthetic fiber.

[0189] In this embodiment, since optical signals are used to detect clothing materials, the detection accuracy is less affected by water mist, and there is no need for autofocus, which helps improve the accuracy of clothing material identification. Furthermore, by utilizing the diffuse reflection of the incident light signal to detect clothing, there is no need for detection through the clothing itself, thus avoiding the defect of failure to detect due to the incident light signal not being able to penetrate the clothing. This further ensures the smooth progress of clothing material identification and helps improve the accuracy of clothing material identification.

[0190] In one possible embodiment of this application, such as Figure 2 As shown, multiple diffuse reflection parameter values ​​are obtained when the clothing diffusely reflects the incident light signal, including:

[0191] S200 controls the emitter of the light detector to repeatedly emit incident light signals to the clothing covering the light detector.

[0192] The multiple transmissions of incident light signals can be preset by setting the time interval between each transmission or by setting the total number of transmissions. This embodiment does not impose specific limitations on this. For example, the incident light signal is transmitted 10 times, with each transmission spaced 10ms apart.

[0193] S202, The receiver of the optical detector receives the reflected light signal from the diffuse reflection of the incident light signal by the clothing multiple times.

[0194] Each incident light signal is diffusely reflected by the clothing, resulting in a reflected light signal. In other words, there is a one-to-one correspondence between the incident light signal and the reflected light signal. Therefore, the number of incident light signals emitted is equal to the number of reflected light signals.

[0195] S204. Based on the wavelength and / or intensity of the reflected light signals received multiple times by the receiving electrode in the photodetector, perform data conversion processing to obtain multiple diffuse reflection parameter values.

[0196] The specific data conversion process is not limited in this embodiment and can be determined according to actual needs. For ease of understanding, in one application scenario, after substituting the wavelength and intensity of the reflected light signal into a pre-set formula, the calculated result is the diffuse reflection parameter value, and this calculation process is the data conversion process.

[0197] In this embodiment, when identifying the material of clothing, incident light signals are emitted multiple times, resulting in the receiver receiving reflected light signals multiple times. These reflected light signals are then converted to obtain multiple diffuse reflection parameter values. On one hand, multiple diffuse reflection parameter values, compared to a single value, help avoid special cases and improve the accuracy of clothing material identification based on diffuse reflection parameter values. On the other hand, instead of directly using information such as the wavelength and intensity of the reflected light signals, data conversion processing is performed to ensure that the standard diffuse reflection value ranges corresponding to different clothing materials differ significantly. This improves the accuracy of clothing material identification and avoids the possibility of no identification due to small differences in the standard diffuse reflection value ranges corresponding to different clothing materials.

[0198] Optionally, in one implementation of this embodiment, the light detection device is an ultraviolet sensor or an infrared sensor, and the emitter and receiver of the light detection device are arranged in parallel under the clothing.

[0199] Parallel tiling means that the transmitter and receiver are arranged side by side and laid flat under the clothing.

[0200] Using this embodiment, the ultraviolet or infrared sensor is inexpensive and unlikely to damage clothing or the human body. The parallel arrangement of the emitter and receiver helps reduce the space occupied by the photodetector and improves the ease of installation.

[0201] Optionally, in one implementation of this embodiment, such as Figure 3 As shown, based on multiple diffuse reflection parameter values ​​and the preset correspondence between clothing materials and diffuse reflection standard value ranges, the clothing material is determined, including:

[0202] S300. Determine a representative value based on multiple diffuse reflection parameter values.

[0203] Representativeness can refer to any aspect or any angle; this embodiment does not impose a specific limitation and can be determined according to actual needs. These actual needs are related to the specific method of obtaining the diffuse reflection parameter values ​​and / or the specific process of determining the corresponding relationships. For example, if only simple algorithms such as addition, subtraction, multiplication, and division are used in calculating the diffuse reflection parameter values, and the wavelength and intensity of the reflected light signal are represented by a constant, then the average value among multiple diffuse reflection parameter values ​​can be used as the representative value. As another example, if the larger or maximum values ​​of the diffuse reflection standard values ​​are used when determining the corresponding relationships, then the representative value is the maximum value of multiple diffuse reflection parameter values.

[0204] S302. Compare the representative value with each diffuse reflectance standard value interval to determine the diffuse reflectance standard value interval to which the representative value belongs.

[0205] In other words, it determines which diffuse reflectance standard value interval the representative value belongs to. If it is within the diffuse reflectance standard value interval P1, then the representative value belongs to P1; if it is within P2, then the representative value belongs to P2.

[0206] S304. Based on the correspondence, determine the clothing material corresponding to the diffuse reflectance standard value range to which the representative value belongs as the clothing material.

[0207] Because there is a correspondence between clothing materials and diffuse reflectance standard value intervals—that is, clothing material 'a' corresponds to diffuse reflectance standard value interval P1, clothing material 'b' corresponds to diffuse reflectance standard value interval P2, clothing material 'c' corresponds to diffuse reflectance standard value interval P3, and so on—once the diffuse reflectance standard value interval to which the representative value belongs can be determined, the clothing material can be identified based on this correspondence, thus confirming the clothing material as that material.

[0208] In this embodiment, the fabric material of the garment is determined based on the standard range of diffuse reflection values ​​to which the representative value belongs, as determined by multiple diffuse reflection parameter values. This helps to improve accuracy.

[0209] Optionally, in one implementation of this embodiment, the representative value includes at least one of the maximum value, minimum value, median value, and average value.

[0210] Using this embodiment, the maximum, minimum, median, and average values ​​are all representative under specific conditions. This allows the representative values ​​to better reflect the characteristics of multiple diffuse reflectance parameter values, thereby increasing the accuracy of determining the fabric material of clothing based on the representative values.

[0211] Optionally, in one implementation of this embodiment, the method further includes:

[0212] After obtaining multiple diffuse reflection parameter values, the validity of the multiple diffuse reflection parameter values ​​is determined based on their stability. Validity includes both valid and invalid values.

[0213] If multiple diffuse reflection parameter values ​​are valid, the clothing material is determined based on the correspondence between the multiple diffuse reflection parameter values ​​and the preset clothing material and diffuse reflection standard value range.

[0214] If multiple diffuse reflection parameter values ​​are invalid, the spatial distribution of the clothing is changed according to the clothing adjustment strategy, and multiple diffuse reflection parameter values ​​are reacquired when the clothing diffusely reflects the incident light signal.

[0215] In other words, after obtaining multiple diffuse reflection parameter values, their validity will be judged first, and the fabric material of the garment will be determined using the multiple valid diffuse reflection parameter values.

[0216] Stability refers to the stability of multiple diffuse reflection parameter values. When evaluating stability, it can be assessed from the perspective of the difference between multiple diffuse reflection parameter values ​​or from the perspective of the fluctuation of multiple diffuse reflection parameter values. This embodiment does not make specific limitations on this.

[0217] In cases where multiple diffuse reflection parameter values ​​are invalid, the spatial distribution of the clothing will be adjusted first, and then the multiple diffuse reflection parameter values ​​will be reacquired. It should be noted that the clothing adjustment strategy aims to change the spatial distribution of the clothing; therefore, this embodiment does not specifically limit this. For ease of understanding, for example, the clothing adjustment strategy could be to adjust the position of the clothing; the specific method of adjustment can be determined according to the actual situation.

[0218] In this embodiment, the validity of multiple diffuse reflection parameter values ​​is assessed. Only when multiple diffuse reflection parameter values ​​are valid is the clothing material determined based on these values ​​and their corresponding relationships, ensuring the accuracy of the determined clothing material. For invalid multiple diffuse reflection parameter values, multiple diffuse reflection parameter values ​​are reacquired. Since reacquiring values ​​also constitutes obtaining multiple diffuse reflection parameter values, their validity is reassessed, and this process is repeated cyclically to improve the accuracy of the determined clothing material.

[0219] Optionally, in one implementation of this embodiment, determining the validity of multiple diffuse reflection parameter values ​​based on the stability of multiple diffuse reflection parameter values ​​includes:

[0220] The validity of multiple diffuse reflection parameter values ​​is determined based on the degree of dispersion of these values, where the degree of dispersion is used to characterize the stability of the multiple diffuse reflection parameter values.

[0221] In this embodiment, the validity of multiple diffuse reflection parameter values ​​is determined based on the degree of dispersion of the multiple diffuse reflection parameter values. The calculation process is simple and helps to reduce the consumption of computing resources.

[0222] Optionally, in one implementation of this embodiment, determining the validity of multiple diffuse reflection parameter values ​​based on the dispersion of multiple diffuse reflection parameter values ​​includes:

[0223] Calculate the average of multiple diffuse reflection parameter values;

[0224] The standard deviation, which characterizes the degree of dispersion, is calculated using the mean and multiple diffuse reflectance parameter values.

[0225] If the standard deviation exceeds the preset effective threshold, then multiple diffuse reflection parameter values ​​are determined to be invalid.

[0226] If the standard deviation does not exceed the effective threshold, then multiple diffuse reflection parameter values ​​are determined to be valid.

[0227] The effective threshold can be obtained experimentally. Specifically, when determining the correspondence, to ensure that the various diffuse reflectance standard value intervals do not overlap, the standard deviation of multiple diffuse reflectance parameter values ​​during the experiment is calculated. The formation of the diffuse reflectance standard value interval is constrained by the standard deviation, thereby determining the effective threshold. The specific process for determining the effective threshold is not limited in this embodiment.

[0228] In this embodiment, the standard deviation is used to measure the dispersion of multiple diffuse reflection parameter values. The calculation process is simple and helps to reduce the consumption of computing resources.

[0229] Optionally, in one implementation of this embodiment, the clothing is located inside a clothing processing drum, and the spatial distribution of the clothing is changed according to a clothing adjustment strategy, including:

[0230] Control the rotation of the garment processing drum to a preset angle.

[0231] It should be noted that the garment adjustment strategy includes preset angles, and may also include the rotation direction and number of rotations of the garment processing drum.

[0232] Using this embodiment, the control process is simple and quick, which helps to improve the efficiency of clothing material identification.

[0233] Optionally, in one implementation of this embodiment, after controlling the clothes processing drum to rotate by a preset angle, the method further includes:

[0234] The garment processing drum is controlled to rotate according to preset dispersion parameters, so that after the garment processing drum stops rotating, multiple diffuse reflection parameter values ​​are reacquired under the condition that the garment diffusely reflects the incident light signal.

[0235] The shaking parameters include the rotation speed and the number of reciprocating rotations of the garment processing drum. Specifically, in one application scenario, when controlling the rotation of the garment processing drum according to the shaking parameters, the drum is first controlled to rotate clockwise, and then counterclockwise to achieve reciprocating rotation. It is important to note that the position of the garment processing drum before rotating according to the shaking parameters is the same as its position after stopping rotation.

[0236] By using this embodiment, after running the shaking parameters, it is beneficial to change the state and arrangement order of the clothes in the clothes processing drum, so that the multiple diffuse reflection parameter values ​​that are re-acquired are less likely to be the same as or highly similar to those previously acquired. This helps to increase the difference between the multiple diffuse reflection parameter values ​​that are previously acquired and those that are re-acquired, making it easier to determine the multiple diffuse reflection parameter values ​​that are re-acquired as valid, thereby reducing the number of times multiple diffuse reflection parameter values ​​are acquired and improving the efficiency of clothing material identification.

[0237] This embodiment also provides a control method for a garment processing device, including:

[0238] The above-described method for identifying clothing material is used to identify the clothing material in the clothing processing drum.

[0239] The operating parameters of the garment processing equipment are controlled according to the material of the garment.

[0240] The operating parameters can be the operating mode that the clothing processing equipment needs to operate, or parameters such as the operating time, operating temperature, and operating speed of a certain operating mode. This embodiment does not make specific limitations on this.

[0241] In this embodiment, the clothing processing equipment employs the aforementioned clothing material identification method to identify the clothing material within the equipment. Furthermore, after obtaining the clothing material, corresponding operating parameters are executed based on it. This ensures that the clothing processing equipment applies different operating parameters to different types of clothing materials during processing, thereby improving the processing effect.

[0242] Optionally, in one implementation of this embodiment, the method further includes:

[0243] Once the number of times the fabric type of the clothes in the garment processing drum is identified reaches a preset threshold, the identification process stops.

[0244] It should be noted that each acquisition of multiple diffuse reflection parameter values ​​is considered as one garment material identification operation. A threshold limit can be set to restrict the number of identification attempts, preventing the garment processing device from remaining in the garment material identification stage for an extended period if multiple diffuse reflection parameter values ​​are consistently invalid.

[0245] By setting a threshold number of times in this embodiment, the number of times clothing materials can be identified can be limited, so that the clothing processing equipment will not be in the clothing material identification stage for a long time, which helps to improve the processing efficiency of the clothing processing equipment.

[0246] In one specific implementation of this application, the light detection device uses an ultraviolet (UV) sensor. The emitter and receiver of the UV sensor are installed flat inside the lifting rib, with the distance between the emitter and receiver and the top of the lifting rib (i.e., where the clothing is placed) being 10 / 15 / 20 mm, etc. The relevant working principle is as follows: the UV emitter emits UV rays, and multiple beams of light are emitted horizontally. Upon contact with the material being tested, the material absorbs different intensities of UV rays depending on its knitting density. The remaining unabsorbed UV rays are reflected back to the receiver after contacting the surface of the material. The intensity of the light received by the receiver is the remaining unabsorbed UV light. After receiving the light intensity, the sensor processes the electrical signal through the MCU chip on the PCB board, converting it into a digital signal. The final measured parameters are then compared using a control method to determine the material of the clothing being tested.

[0247] Explanation of the principle:

[0248] The ultraviolet spectrum used has a wavelength of 100-400nm. The wavelength of absorption is calculated according to quantum theory as ΔE = hv = hc / λ. The program can calculate the emitted wavelength and the wavelength received after diffuse reflection through further data processing algorithms. The following control method requires comparing the standard deviation with the average value to measure the deviation of 10 collected values ​​from the average value. After the standard deviation and the degree of deviation are small, the obtained average value is compared with the preset value to determine the specific range and the type of material.

[0249] Parameter description:

[0250] △a represents the range of values ​​obtained by converting a specific wavelength for a given material using the above formula and then differentiating it. 'a' is the average value after 10 samplings, and the standard deviation is the stable value obtained by comparing each sampled value with the average. Beyond △a, different materials correspond to different preset value ranges.

[0251] The method includes the following processing steps:

[0252] When clothes are placed into the drum, the drive motor of the rear drum starts weighing and detecting changes in the clothes inside. The current of the drive motor changes accordingly, confirming that clothes have been placed inside the drum. The motherboard then sends an electrical signal to the ultraviolet sensor inside the lifting rib. The sensor starts working and detects the material, capturing data every 2 seconds for a total of 10 times. These 10 data points form a group, and the average value 'a' of the group is calculated, along with the standard deviation for each data point. The difference between the 10 captured data points and the average value is verified. If the standard deviation and the average value 'a' are large, it means that the measured 10 data points deviate significantly from the average value, indicating that the detected material may be multiple materials. In this case, the detection angle of the sensor in lifting rib 1 needs to be adjusted. The motor needs to be powered to adjust the angle. First, the drum is rotated forward by an angle α (60°), and then rotated back and forth at a low speed of 50 r / min to perform a cradle wash (i.e., running the shaking parameters). This shakes the clothes to a certain extent, causing a certain range of changes in the pile state of the clothes. After rotating for 1 minute, the rotation is stopped. The ultraviolet sensor in lifting rib 1 then detects the relationship between the standard deviation and the average value 'a' again. If the standard deviation is small, there is no need to control the rotation angle of the drive motor again, and the process proceeds directly to the next step of comparing the average value 'a' with the preset range Δa. If the standard deviation data is still too large, it is necessary to drive the motor to rotate by an angle β (120°) and rotate the inner drum back and forth at a low speed of 60r / min to shake the clothes to some extent during the cradle wash.

[0253] The average value 'a' is compared with the closest preset value '△a' to determine if it falls within or outside the specified range. If within the range, the material is identified based on the corresponding range preset by the main control board's big data. If outside the range, the sensor's diffuse reflection angle is inaccurate, and this is reported to the main control board. Upon receiving this feedback, the main control board further controls the motor to rotate by an angle 'α'. The motor performs a low-speed, forward and reverse rotation cradle wash for 1 minute before stopping. The average value 'a' is then compared with the preset range '△a' again. If it still falls outside the range, the motor is adjusted by an angle 'β', and the motor performs another low-speed, forward and reverse rotation cradle wash for 1 minute before stopping. This process is repeated to improve the sensor's testing accuracy by adjusting the motor angle.

[0254] The purpose and reason for cradle wash: The cradle wash program shakes the clothes in the drum to a certain extent, preventing them from piling up.

[0255] Once it is determined that the standard deviation and average value of this test meet the judgment requirements, the next step is to adjust the washing mode for different types of clothing. For example, if the clothing is determined to be cotton, the number of rinses will be increased to prevent detergent residue, the spin speed will be reduced to prevent wrinkles from worsening, and the spin time will be extended after reducing the spin speed.
