[0002] Clothing processing equipment is an indispensable part of daily life, capable of performing processes such as washing, dehydration, drying, and care for clothing, 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 models typically identify the material of the clothing before processing, allowing different processing parameters to be applied to different materials, thus improving the processing effect.

[0003] Most washing machines currently use testing equipment to detect the material of the clothes inside the processing drum. However, in actual use, it has been found that most testing equipment is limited by its installation location, making it difficult to accurately detect the clothes inside the drum in some cases, thus reducing the accuracy of the test results. Summary of the Invention

[0004] This application provides a lifting rib to at least solve the technical problem of decreased accuracy of detection results.

[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 support plate;

[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 support plate is disposed within the installation space and can move along the length direction of the lifting rib body. The support plate is provided with a detection element for optical signal detection.

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

[0009] In this embodiment, a movable support plate is provided in the lifting rib body, and a detection element is provided on the support plate, so that the position of the detection element can change with the movement of the support plate, thereby improving the detection accuracy of the detection element as the position changes, which helps to improve the accuracy of the detection results.

[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 driving component is driven to the support plate to drive the support plate to move along the length direction of the lifting rib body.

[0016] Using this implementation, the drive assembly can move the support plate, improving the convenience and stability of controlling the support plate's movement. The drive assembly is positioned within the installation space, which helps protect it from water ingress, extending its lifespan. It also helps prevent the drive assembly from contacting 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 driver and a transmission component, the input end of the transmission component is connected to the output shaft of the driver, and the output end of the transmission component is connected to the support plate.

[0023] When the magnet moves with the support plate to the position corresponding to the proximity switch, the proximity switch is triggered.

[0024] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, a plurality of proximity switches are provided along the moving direction of the support plate.

[0025] Using this implementation method, when the proximity switch is triggered, it can generate an electrical signal. The movement of the support plate can be controlled by the electrical signal, so that the proximity switch can automatically control the support plate to stop or start moving, thereby improving the control accuracy and convenience of the support plate.

[0026] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the convex wall has a mounting groove recessed from the first wall toward the inner wall of the processing cylinder, the mounting groove having an inner space, and the mounting space including the inner space.

[0027] The support plate is at least partially located within the slot space and moves within the slot space so that the detection element can pass through the mounting slot for optical signal detection, and the proximity switch is disposed on the slot wall of the mounting slot.

[0028] In this implementation, a mounting slot is created, allowing the support plate to move within it, facilitating optical signal detection by the sensor on the support plate. A proximity switch is mounted on the slot wall, making it easy to install and ensuring its proximity to the support plate, thus improving the accuracy of the proximity switch's activation.

[0029] 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 length direction of the lifting rib body.

[0032] 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.

[0033] 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, support plate, proximity switch, drive assembly and other parts, and improving their lifespan.

[0034] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the detection element includes at least one of a receiving electrode and a transmitting electrode;

[0046] 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.

[0047] 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.

[0048] 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.

[0049] First, the terminology used in the embodiments of this application will be introduced.

[0050] 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.

[0051] 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.

[0052] Clothing processing equipment is an indispensable part of daily life, capable of washing, spinning, drying, and conditioning 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 models typically identify the material of the clothes before processing, allowing different processing parameters to be applied to different materials, thus improving the processing effect.

[0053] Most washing machines currently use testing equipment to detect the material of the clothes inside the processing drum. However, in actual use, it has been found that most testing equipment is limited by its installation location, making it difficult to accurately detect the clothes inside the drum in some cases, thus reducing the accuracy of the test results.

[0054] Based on this, this application provides a lifting rib for mounting on the processing cylinder of a garment processing device, as shown in the following embodiment. Figure 1-2 The schematic diagram of the lifting rib shown is shown. The lifting rib includes a lifting rib body 1 and a support plate 2.

[0055] 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.

[0056] The support plate 2 is set in the installation space and can move along the length direction of the lifting rib body 1. The support plate 2 is provided with a detection element 3 for optical signal detection.

[0057] The convex wall 11 has a light-transmitting portion at least in the part opposite to the moving path of the detection element 3 so that the detection element 3 can perform optical signal detection.

[0058] 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 inner wall of the processing cylinder. This embodiment does not make specific limitations in this regard.

[0059] 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.

[0060] 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 around the bottom. Preferably, if the opening of the processing cylinder faces upwards 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 forwards 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 upwards towards the garment processing equipment to form a convex wall 11.

[0061] 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.

[0062] The interior of the protruding 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 support plate 2 is located within the installation space and is movable. The support plate 2 can move along the height direction of the lifting rib body 1 or along the width direction of the lifting rib body 1. It should be noted that the movable arrangement of the support plate 2 within the installation space specifically means that the support plate 2 is reciprocally movable within the installation space. Preferably, the support plate 2 can reciprocate within the installation space along the height direction of the lifting rib body 1, thereby driving the detection element 3 to reciprocate along the height direction of the lifting rib body 1.

[0063] 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 moving path of the detection element 3. However, since the detection element 3 can move with the support plate 2, there is a light-transmitting part at any position on the moving path 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.

[0064] In this embodiment, a movable support plate 2 is provided in the lifting rib body 1, and a detection element 3 is provided on the support plate 2, so that the position of the detection element 3 can change with the movement of the support plate 2, thereby improving the detection accuracy of the detection element 3 with the change of position, which helps to improve the accuracy of the detection results of the detection element 3.

[0065] In conjunction with the first aspect, in one optional implementation of the embodiments 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.

[0066] 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.

[0067] 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.

[0068] By adopting this implementation method, 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.

[0069] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, 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.

[0070] 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.

[0071] 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.

[0072] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the lifting rib further includes a driving component 4, which is disposed in the installation space;

[0073] The drive assembly 4 is connected to the support plate 2 to drive the support plate 2 to move along the length direction of the lifting rib body 1.

[0074] 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.

[0075] In one application scenario, the light-transmitting part is located on the first wall 111, and the driving component 4 is used 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 closer to or further away from the light-transmitting part when it moves.

[0076] In this embodiment, the drive assembly 4 can drive the support plate 2 to move, improving the convenience and stability of controlling the movement of the support plate 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.

[0077] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the drive component 4 includes a driver 41 and a transmission component 42, the input end of the transmission component 42 is connected to the output shaft of the driver 41, and the output end of the transmission component 42 is connected to the support plate 2.

[0078] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the driver 41 is a motor, which is mounted in the installation space via a motor support plate 43;

[0079] Transmission component 42 includes gear 4 and rack.

[0080] Gear 4 is mounted on the drive shaft of the motor. The rack is connected to the support plate 2 and meshes with gear 4. The lifting rib is provided with a slide rail fixed relative to the position of the lifting rib, and the rack is slidably mounted on the slide rail.

[0081] In one embodiment, the rack can be a flexible rack, forming a conveyor belt-like structure to increase the range of movement of the support plate 2 in the length direction of the lifting rib.

[0082] In one embodiment, the slide rail consists of two tracks disposed within the installation space. The extension direction of the tracks is parallel to the movement direction of the support plate 2, and both ends of the tracks are fixedly connected to the inner wall of the convex wall. A rack is slidably disposed between the two tracks.

[0083] By employing this implementation method, the transmission of gear 4 and rack helps to improve the stability of the movement of support plate 2 by relying on transmission component 42.

[0084] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, a magnet is provided on the support plate 2, and a proximity switch is provided at a position in the installation space opposite to the moving path of the support plate;

[0085] When the magnet moves with the support plate 2 to the position corresponding to the proximity switch, the proximity switch is triggered.

[0086] In one embodiment, the proximity switch is located on one side of the movement path. Specifically, there are multiple proximity switches, and the arrangement of the multiple proximity switches is parallel to the direction of the movement path.

[0087] When the proximity switch is triggered, it generates an electrical signal, which controls the movement of the support plate 2, allowing the proximity switch to automatically stop or start its movement. Preferably, when the proximity switch is triggered, it generates an electrical signal to stop the support plate 2. Specifically, the electrical signal generated by the proximity switch controls the motor braking, causing the support plate 2 to stop moving.

[0088] This embodiment improves the control accuracy and convenience of the support plate 2.

[0089] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, a plurality of proximity switches are provided along the moving direction of the support plate 2.

[0090] Multiple proximity switches are arranged along the moving direction of the support plate 2.

[0091] By using this embodiment, multiple proximity switches can be used to set multiple stopping points for the support plate 2, thereby improving the control accuracy and convenience of the support plate 2.

[0092] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the convex wall 11 has a mounting groove recessed from the first wall 111 toward the inner wall of the processing cylinder, the mounting groove having an inner space, the mounting space including the inner space.

[0093] The support plate 2 is at least partially located in the groove space and moves in the groove space so that the detection element 3 can pass through the mounting groove for optical signal detection, and the proximity switch is set on the groove wall of the mounting groove.

[0094] It should be noted that, in this embodiment, a mounting groove is formed on the first wall 111, and this groove is the light-transmitting part. This allows the light signal to pass through the groove and enter or leave the mounting groove during transmission.

[0095] In this embodiment, by creating a mounting slot, the support plate 2 can move within the slot, facilitating optical signal detection by the detection element 3 on the support plate 2. A proximity switch is mounted on the slot wall, making it easy to install and close to the support plate 2, thus improving the accuracy of the proximity switch triggering. The mounting space is divided into a mounting slot and a receiving space. Since the receiving space is located between the first wall 111, the slot wall, and the second wall 112, the drive component 4 within the receiving space is less susceptible to interference from outside the receiving space, improving the operational stability of the drive component 4.

[0096] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the mounting groove penetrates the second wall 112 along the length direction of the lifting rib body 1.

[0097] 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.

[0098] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the mounting groove has an opening serving as a light-transmitting portion; or,

[0099] 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. The sealing plate 7 is a light-transmitting plate that serves as a light-transmitting part.

[0100] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the detection element 3 includes at least one of a receiving electrode 32 and a transmitting electrode 31;

[0101] The emitter 31 is used to transmit optical signals, and the receiver 32 is used to receive optical signals.

[0102] This implementation method 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, support plate 2, proximity switch, drive assembly 4 and other parts, and improving their lifespan.

[0103] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the detection element 3 includes a receiving electrode 32 and a transmitting electrode 31, which are arranged side by side on the support plate 2 along the width direction of the lifting rib body 1.

[0104] Using this implementation method, the side-by-side arrangement of the receiving electrode 32 and the transmitting electrode 31 facilitates the detection of clothing by relying on diffuse reflection.

[0105] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the detection element 3 includes an ultraviolet sensor or an infrared sensor.

[0106] 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.

[0107] 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 the above-described processing cylinder.

[0108] For ease of understanding, Figure 1 and Figure 2 The lifting ribs in the design will be further explained as follows.

[0109] Structural Description:

[0110] The lifting rib cover (e.g., the first wall 111) is made of ultraviolet-transmitting glass, but the four ribs for the screw holes are injection molded.

[0111] The ultraviolet sensor (e.g., detection element 3) consists of an emitter and a receiver. The emitter and receiver are installed inside the lifting rib in a flat configuration.

[0112] Support plate. The emitter and receiver of the ultraviolet sensor are laid flat on the bottom of the support plate, which is equipped with the ultraviolet sensor. The emitter and receiver are fixed to the protrusions on the left and right sides of the support plate.

[0113] The slide rail and support plate form a flat surface. The bottom of the support plate has another fixing plate that mates with the rack and slide rail, fixed to the upper surface of the slide rail; this upper surface is flat.

[0114] The rack and pinion mechanism, along with the slide rail, works in conjunction with a gear to rotate, which in turn drives the rack to move. This movement of the rack, in turn, causes the ultraviolet sensor to move back and forth.

[0115] Motor support plate. The motor support plate is embedded in the side of the lifting rib cover.

[0116] An electric motor (e.g., driver 41). The motor is a small motor, fixed on a motor support plate, with gears mounted on the motor shaft, and the rotor drives the gears to rotate.

[0117] Gears. The rotation of gears drives the movement of racks. The motor can rotate in both directions, driving the gears to rotate in both directions, thus achieving the effect of moving the racks back and forth.

[0118] The lower cover of the lifting rib. The upper cover of the lifting rib is installed and fixed by four screws. The upper and lower covers of the lifting rib protect the various components embedded inside the lifting rib, achieving a waterproof and sealing effect.

[0119] Control logic and principle description:

[0120] The top and sides of the lifting rib are made of transparent glass, allowing ultraviolet light to pass through. The motor is a DC motor capable of forward and reverse rotation. The motor's forward and reverse rotation drives a rack and pinion mechanism. In forward rotation, the rack rotates counter-clockwise, moving the ultraviolet sensor support plate forward; in reverse rotation, the rack rotates clockwise, moving the ultraviolet sensor support plate backward. This movement of the ultraviolet sensor within the lifting rib allows it to emit ultraviolet light after being powered on. The ultraviolet light passes through the glass and reaches the surface of the clothing. Different clothing materials absorb ultraviolet light to varying degrees; after absorbing some, the remaining ultraviolet light is diffusely reflected back into the lifting rib, passes through the glass, and reaches the receiving electrode of the ultraviolet sensor. The receiving electrode receives the diffusely reflected ultraviolet light and compares it with a preset value to determine the type of material.

[0121] While the ultraviolet sensor moves back and forth inside the lifting ribs, it continuously operates and continuously detects the material of the clothing inside the drum. During continuous monitoring, it can also work in conjunction with the rotation of the drum to continuously tumble the clothing inside, causing the clothing to be shaken and patted above the lifting ribs as much as possible. If the clothing is found to be above the lifting ribs, it can be continuously detected by the ultraviolet sensor, achieving real-time multi-range detection, improving detection efficiency and the comprehensiveness of clothing material detection.

[0122] The emitter and receiver of the ultraviolet sensor are mounted on the support plate in a flat position. The reason for this flat mounting is that if diffuse reflection detection is used, the emitter and receiver need to be mounted flat.

[0123] The sequence numbers or order of description of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments.
