[0057] BACKGROUND

[0058] Laundry treatment equipment is an indispensable equipment in daily life, which can inject washing, dehydration, drying, care and other treatments to clothes, greatly improving the convenience of clothes treatment. With the development of science and technology and the improvement of user demand, the treatment accuracy of laundry treatment equipment on clothes has also been improved. Taking a washing machine as an example, the current washing machine usually identifies the material of the clothes before treating the clothes, so that clothes of different materials can adopt different treatment parameters, which helps to improve the treatment effect of the clothes.

[0059] However, most of the current washing machines detect the material of the clothes in the treatment drum of the laundry treatment equipment by installing detection instruments. But in actual use, it is found that most detection instruments will be limited by their installation position, making it difficult to accurately detect the clothes in the treatment drum in some cases, thereby reducing the accuracy of the detection result.

[0060] Specifically, as shown in Figure 1 and Figure 2 The first aspect of the embodiment of the present application provides a clothes material detection method, which comprises:

[0061] obtaining a plurality of parameter values collected by the detection member in the current detection state, the detection state including the detection distance of the detection member, the parameter value being used to represent the clothes material, the parameter value being determined according to the light signal collected by the detection member, the detection member being used to collect the light signal after the clothes in the clothes treatment drum diffusely reflects the incident light signal;

[0062] calculating an average value and a standard deviation of the plurality of parameter values, performing the first clothes material detection according to a comparison result of the average value and a parameter value interval under a current detection state, and according to a comparison result of the standard deviation and a preset standard deviation;

[0063] performing the clothes material identification according to a comparison result of the average value of the plurality of parameter values and the parameter value interval, and a comparison result of the standard deviation of the plurality of parameter values and a standard deviation interval, wherein the parameter value interval corresponds to the clothes material and the current detection state.

[0064] The clothes material detection method provided in the embodiments can obtain the average value and the standard deviation of the plurality of parameter values during detection, and adjust the detection state of the detection member according to the average value and the standard deviation, so that the data after detection can more accurately reflect the clothes material in the clothes treatment drum, thereby enabling the clothes to be subjected to a targeted washing strategy according to the detected clothes material, to improve the washing effect on the clothes.

[0065] Specifically, by judging whether the average value of the plurality of parameters falls within a preset average value interval under the current detection state, the calculated average value can be compared with the interval corresponding to each material, such as cotton, hemp, silk, polyester fiber, wool, etc. By judging whether the standard deviation of the plurality of parameters falls within a preset standard deviation interval, it can be determined whether the sampling data is stable, and whether the clothes material detection needs to be performed again according to the stable procedure.

[0066] Specifically, in some embodiments, the detection state further includes a detection angle of the detection member.

[0067] The first clothes material detection according to the comparison result of the average value and the preset average value under the current detection state, and according to the comparison result of the standard deviation and the preset standard deviation, includes:

[0068] If the average value is within the preset average value interval range, and the standard deviation is within the preset standard deviation interval range, the clothes material is determined according to the preset average value interval range.

[0069] If at least one of the average value and the standard deviation is not within the corresponding preset interval range, the detection distance and / or the detection angle of the detection member are adjusted to perform the first clothes material detection again.

[0070] When the average value falls within the preset average value interval of the current detection state, it indicates that the average value of the collected data can correspond to the preset average value interval representing the specific clothing material, but further judgment is needed on the dispersion degree of the collected data to determine whether the obtained data is stable. Based on this, by obtaining the standard deviation of multiple data and comparing the standard deviation with the preset standard deviation, it can be reflected whether the collected data is stable, and the material of the clothing is determined according to the stability of the data or the detection distance of the detection piece is adjusted.

[0071] If the average value does not fall within the preset average value interval of the current detection state, it indicates that the collected data cannot correspond to the preset average value interval representing the specific clothing material, and the detection state of the detection piece needs to be adjusted to reacquire the collected data.

[0072] It should be noted that the detection piece can output parameter values representing the material of the clothing when it is in different detection positions, and the clothing treatment device is preset with multiple average value interval-material corresponding tables. When the detection piece is in different detection states, it corresponds to a group of average value interval-material corresponding tables.

[0073] Further, in some embodiments, at least one of the average value and the standard deviation is not within the corresponding preset interval range, including:

[0074] In the first case, the average value is not within the preset average value interval range, or

[0075] In the second case, the average value is within the preset average value interval range, but the standard deviation is not within the preset standard deviation interval range.

[0076] That is, when the average value of the collected data is not within the preset average value interval range of the current detection state, the detection angle of the detection piece needs to be adjusted.

[0077] When the average value of the collected data is within the preset average value interval range of the current detection state, but the standard deviation of the collected data is not within the preset standard deviation interval range, the detection distance of the detection piece needs to be adjusted.

[0078] Further, in some embodiments, the clothing material detection method comprises:

[0079] In the first case, the detection angle of the detection piece is adjusted, and the average value and the standard deviation of the multiple parameter values are reacquired after the detection angle is adjusted, and the first clothing material detection is performed according to the reacquired average value and the standard deviation.

[0080] Further, in the first case, the detection angle of the detection member is adjusted, and after the detection angle is adjusted, the average value and the standard deviation of the plurality of parameter values are re-acquired, and the first clothes material detection is performed according to the re-acquired average value and standard deviation, including:

[0081] The plurality of parameter values collected by the detection member at the current detection angle are acquired, and the average value and the standard deviation of the plurality of parameter values are recalculated, and it is judged whether the average value is within a preset average value interval range at the current detection angle;

[0082] If the average value is within the preset average value interval range at the current detection angle, it is judged whether the standard deviation is within a preset standard deviation interval range;

[0083] If the average value is not within the preset average value interval range at the current detection angle, the detection angle of the detection member is re-adjusted for the first clothes material detection.

[0084] Further, the clothes material detection method further includes:

[0085] After the detection angle of the detection member is adjusted for the preset number of times, the re-acquired average value is still not within the preset average value interval range, the state of the clothes in the clothes treatment drum is adjusted to re-perform the clothes material detection until the re-acquired average value is within the corresponding preset average value interval range;

[0086] The method for adjusting the state of the clothes in the clothes treatment drum includes: controlling the clothes treatment drum to rotate at a preset rotation rhythm for a first preset time length;

[0087] The preset rotation rhythm includes clothes treatment drum forward rotation-stop-reverse rotation-stop.

[0088] In any of the above embodiments, the clothes material detection method includes:

[0089] In the second case, the detection distance of the detection member is adjusted, and after the detection distance is adjusted, the standard deviation of the plurality of parameter values is re-acquired, and the first clothes material detection is performed according to the re-acquired standard deviation.

[0090] Further, in the second case, the first clothes material detection is performed according to the re-acquired standard deviation, including:

[0091] It is judged whether the re-acquired standard deviation is within a preset standard deviation interval range;

[0092] If the standard deviation is within the preset standard deviation interval range, the clothes material is determined according to the interval range of the preset average value;

[0093] If the standard deviation is not within the preset standard deviation interval range, the detection distance of the detection member is adjusted again until the re-acquired standard deviation is within the preset standard deviation interval range.

[0094] In any of the above embodiments, the clothes material detection method further comprises:

[0095] After detecting a material of clothes in the clothes treatment drum, the clothes in the clothes treatment drum are shaken, and a second clothes material detection is performed after the clothes are shaken, and after detecting a second clothes material, the clothes are continuously shaken, a third clothes material detection is performed, and until an Mth clothes material detection is performed;

[0096] Wherein M≥3.

[0097] Further, in some embodiments, the clothes material detection method further comprises:

[0098] When adjusting the detection distance of the detection member, the detection member is controlled to move to the side of the clothes to shorten the detection distance of the detection member.

[0099] Further, in some embodiments, the clothes material detection method further comprises:

[0100] The washing strategy is adjusted according to the detected clothes material.

[0101] In order to more clearly understand the detection logic of the clothes material detection method in the embodiments of the present application, the following will be combined with Figure 2 for specific description:

[0102] Parameter description: Figure 2 In the table, △a corresponds to cotton, △b corresponds to hemp, △c corresponds to silk, △d corresponds to wool, and △e corresponds to polyester fiber. The average value of the sampling data is a, and the standard deviation is S.

[0103] The control logic and principle are described as follows:

[0104] The user puts the clothes into the clothes treatment drum, one of the lifting ribs inside the washing machine is equipped with an ultraviolet sensor, and the material of the clothes is identified through the diffuse reflection of the ultraviolet sensor. In the initial state, the ultraviolet sensor is installed inside the lifting rib at a distance d1 (20 mm) from the top end of the lifting rib, and the sensor starts to collect material detection data of the clothes in the drum.

[0105] The parameters were collected 10 times from the clothes inside the drum, once every 2 seconds. The drum did not rotate during the collection. The average value 'a' of the collected data was calculated. The collected data was compared with the average value 'a', and the standard deviation S of this set of sampled data was also calculated. The average value 'a' was then compared with the corresponding range for each material, such as cotton, linen, silk, polyester fiber, wool, etc.

[0106] If the average value 'a' falls within the corresponding material's range, then the standard deviation 'S' of the sample data is determined. Is the value of 'S' within the range [2, 5]? If the standard deviation falls within [2, 5], it indicates that the dispersion of the sampled data is small and the data is relatively stable. After the data stabilizes, the washing parameters, such as the motor spin speed and drying time, are adjusted to match the tested material. If the standard deviation does not fall within the range of [2,5], the distance of the ultraviolet sensor inside the lifting rib is controlled by the lead screw and gear in conjunction with the motor and adjusted to d2 (15mm). After adjusting the distance, the current standard deviation is recalculated. Because the range of the same material will be different after adjusting the distance, but the main ranges of each distance overlap. After adjusting from the original distance d1 (20mm) to d2 (15mm), the range of material parameters becomes larger {for example, when the detection distance is 20mm, the material parameters of cotton are 100-130, and when the detection distance is 15mm, the range of material parameters of cotton will be expanded by 10 in the upper and lower limits, becoming 90-140}. Therefore, the standard deviation S calculated under this distance condition can also be used to compare the standard deviation under this condition again to see if it falls within the range of [2,5]. If the standard deviation under this condition falls within this range, there is no need to adjust the distance again, which proves that the stability of the sampled data at this time is good and the dispersion is low. If the standard deviation S still does not fall within the range [2,5], the distance of the UV sensor inside the lifting rib needs to be adjusted to d3 (10mm). After adjusting the distance, verify again whether the standard deviation S falls within the range [2,5]. Repeat this process of adjusting the three distances multiple times to check the standard deviation until S falls within the range [2,5], at which point the data will be stable. Once the data is stable, adjust the washing parameters and spin speed based on the proportion of the tested material parameters. It is worth noting that when a clothing material is detected, the clothes drum is rotated to shake the clothes inside, and the material inside the drum is re-acquired after shaking. If 10 tests are performed, the clothes need to be shaken 9 times. If 8 tests show cotton and 2 show silk, the washing mode should be a combination of cotton / linen and gentle washing modes.

[0107] The above describes the control logic when the average value 'a' falls within the corresponding material's range. When the average value 'a' does not fall within the corresponding material's range, the following control logic applies: If the average value 'a' does not fall within the corresponding material's range, the main control board needs to rotate the drive motor by an angle α (60°) to change the angle of the ultraviolet sensor inside the lifting ribs. After changing the angle, the material parameters of the clothes in the drum are checked again to determine if the average value falls within the preset range for each material (△a--△e). If it falls within the preset range for each material, the standard deviation S is then checked to see if it is stable within the range of [2,5]. The method for adjusting the standard deviation is the same as described in the previous paragraph, achieved by adjusting the ultraviolet sensor through the push rod motor. If the average value does not fall within the preset range for each material, the drum motor's rotation angle is adjusted again for testing. The cradle wash cycle rotates continuously in both directions for 1 minute, and the check is repeated until the average value falls within the preset range. Once both the average value and standard deviation meet the criteria, the washing mode can be adjusted based on the detected material type. For example, if out of 10 tests, 8 are cotton and 2 are linen, the cotton / linen washing mode will be used directly. If 8 are cotton and 2 are wool, the machine will issue an alarm, prompting the user to remove the wool and then run the cotton / linen washing mode again. If 6 are cotton and 4 are synthetic fibers, an algorithm combining cotton / linen and synthetic fibers will be used to adjust the washing parameters, or AI-powered intelligent washing will be performed.

[0108] 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.

[0109] 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.

[0110] 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).

[0111] In one embodiment, in order to determine the material of the clothing, a standard range of diffuse reflection values ​​is preset (i.e., the parameter value range mentioned above). Different standard ranges of diffuse reflection values ​​correspond to different clothing materials. In other words, the standard range of diffuse reflection values ​​and the clothing material have a corresponding relationship.

[0112] 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.

[0113] 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 the diffuse reflectance standard value range P1; this is the correspondence. Therefore, when the diffuse reflectance parameter value is within P1, it can be determined that the clothing material is 'a'.

[0114] In this embodiment, the correspondence between parameter value ranges and clothing material and detection state can be obtained by conducting experiments under different detection states (detection distances).

[0115] Furthermore, such as Figures 3-10 As shown, the second aspect of this application also provides a garment processing device, which includes the garment material detection method provided in the first aspect of this application.

[0116] 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, and hats 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] Based on this, the embodiments of this application first provide a lifting rib, taking the application of this lifting rib on the processing drum of a garment processing device as an example, referring to... Figures 3-10 The schematic diagram of the lifting rib shown is shown. The lifting rib includes a lifting rib body 1 and a support plate 2.

[0121] The lifting rib body 1 has: a protruding wall 11 that protrudes from the inner wall of the processing cylinder into the interior of the processing cylinder, and an installation space formed inside the protruding wall 11;

[0122] The support plate 2 is movably installed in the installation space, and the support plate 2 is provided with a detection element 3 for optical signal detection;

[0123] 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.

[0124] 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.

[0125] 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.

[0126] In one application scenario, the inner wall of the garment processing drum includes a bottom and a side wall. The bottom is opposite to the opening of the drum, and the side wall is located between the bottom and the opening, forming a ring around the opening. Preferably, if the opening of the drum faces upwards towards the garment processing equipment, a lifting rib body 1 is disposed at the bottom of the drum, extending in the direction of the opening to form a convex wall 11. If the opening of the drum faces forwards towards the garment processing equipment, a lifting rib body 1 is disposed at the side wall of the drum, extending upwards towards the garment processing equipment to form a convex wall 11.

[0127] 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.

[0128] 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.

[0129] 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 move with the support plate 2, there is a light-transmitting part at any position along the movement 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.

[0130] 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.

[0131] In one possible embodiment of this application, 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;

[0132] The second wall 112 is integrally formed or sealed to the inner wall of the processing cylinder, and the second wall 112 and the first wall 111 form an installation space.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] Optionally, in one implementation of this embodiment, 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;

[0137] The lifting rib body 1 also includes a lower cover 12 that is detachably connected to the second wall 112, and the lower cover 12 and the protruding wall 11 form an installation space.

[0138] 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.

[0139] 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.

[0140] Optionally, in one implementation of this embodiment, the lifting rib further includes a driving component 4, which is disposed in the installation space;

[0141] The drive assembly 4 is driven to the support plate 2 to drive the support plate 2 to move closer to or away from the light-transmitting part.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] Optionally, in one implementation of this embodiment, 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.

[0146] The driver 41 has an output shaft. After the driver 41 is started, the output shaft moves, thereby driving the transmission component 42 connected to the output shaft to move. The movement of the transmission component 42 drives the support plate 2 to move, thereby achieving the driving effect on the support plate 2.

[0147] 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 include, for example, converting linear motion into rotational motion or vice versa.

[0148] In this embodiment, by setting the transmission component 42 to transmit the driving force of the driver 41 to the support plate 2, on the one hand, it helps to improve the stability of the movement of the support plate 2 by relying on the transmission component 42, and on the other hand, it helps to correct the driving force of the driver 41 by relying on the transmission component 42, such as correcting the direction and / or magnitude of the driving force.

[0149] Optionally, in one implementation of this embodiment, the driver 41 is a motor, which is installed in the installation space through the motor cover 43;

[0150] The transmission component 42 includes a first gear 421, a lead screw 422 and a second gear 423 disposed at one end of the lead screw. The first gear 421 is disposed on the output shaft of the motor. One end of the lead screw 422 is connected to the first gear 421 through the second gear 423. The other end of the lead screw is rotatably connected to the lifting rib body 1.

[0151] One end of the support plate 2 is provided with a threaded hole 21, and the lead screw 422 drives the lead screw 422 of the support plate 2 through the threaded hole 21.

[0152] In one application scenario, the motor is a rotary type, meaning that after the motor starts, its output shaft rotates. The first gear 421 rotates along with the output shaft and simultaneously drives the second gear 423 to rotate. The size, number of teeth, and tooth pitch of the first gear 421 and the second gear 423 can be the same or different, and the rotational speed of the second gear 423 differs from that of the first gear 421 at different times, thus achieving speed regulation. The lead screw 422 rotates under the drive of the second gear 423, causing the support plate 2, which is threadedly connected to the lead screw 422, to move along the height direction of the lead screw 422.

[0153] In this embodiment, the first gear 421, the lead screw 422, and the second gear 423 exhibit high stability, which helps improve the stability of the movement of the support plate 2. Furthermore, when the dimensions of the first gear 421 and the second gear 423 are different, the movement speed transmitted to the support plate 2 will also be different, facilitating the adjustment of the movement speed of the support plate 2.

[0154] Optionally, in one implementation of this embodiment, a magnet 22 is provided on the support plate 2, and a proximity switch 5 is provided at a position opposite to the magnet 22 in the installation space;

[0155] When magnet 22 moves with support plate 2 to the position corresponding to proximity switch 5, proximity switch 5 is triggered.

[0156] When proximity switch 5 is triggered, it generates an electrical signal, which controls the movement of support plate 2, allowing proximity switch 5 to automatically stop or start moving support plate 2. Preferably, when proximity switch 5 is triggered, it generates an electrical signal to stop the movement of support plate 2. Specifically, the electrical signal generated by proximity switch 5 is used to control the motor braking, causing support plate 2 to stop moving.

[0157] This embodiment improves the control accuracy and convenience of the support plate 2.

[0158] Optionally, in one implementation of this embodiment, multiple proximity switches 5 are provided along the moving direction of the support plate 2.

[0159] Multiple proximity switches 5 are arranged along the moving direction of the support plate 2.

[0160] By using this embodiment, multiple proximity switches 5 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.

[0161] Optionally, in one implementation of this embodiment, a mounting groove 6 extending into the inner wall of the processing cylinder is provided on the first wall 111. The groove wall of the mounting groove 6 and the second wall 112 form a receiving space. The mounting space includes the mounting groove 6 and the receiving space, and the mounting groove 6 communicates with the receiving space.

[0162] The support plate 2 is located in the mounting groove 6 and moves within the mounting groove 6, the drive assembly 4 is located in the receiving space, and the proximity switch 5 is disposed on the groove wall of the mounting groove 6.

[0163] 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 installation groove 6 and the receiving space.

[0164] It should be noted that, in this embodiment, a slot 6 for mounting is formed on the first wall 111, and this slot is the light-transmitting part. This allows the light signal to pass through the slot and enter or leave the mounting groove 6 during transmission.

[0165] In this embodiment, by creating a mounting slot 6, the support plate 2 can move within the mounting slot 6, facilitating optical signal detection by the detection element 3 on the support plate 2. A proximity switch 5 is mounted on the slot wall formed by the mounting slot 6, making the proximity switch 5 easy to install and close to the support plate 2, thus improving the accuracy of the proximity switch 5 being triggered. The installation space is divided into the mounting slot 6 and a receiving space. Since the receiving space is located between the first wall 111, the slot wall of the mounting slot 6, 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.

[0166] 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.

[0167] 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.

[0168] Optionally, in one implementation of this embodiment, the lifting rib further includes a sealing plate 7, which is connected to the first wall 111 and the second wall 112 to cover the mounting groove 6.

[0169] The sealing plate 7 is a light-transmitting plate;

[0170] The position corresponding to the sealing plate 7 forms a light-transmitting part.

[0171] Among them, the sealing plate 7 is detachably connected to the lifting rib body 1.

[0172] 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, support plate 2, proximity switch 5, drive assembly 4 and other parts, and improving their lifespan.

[0173] Optionally, in one implementation of this embodiment, the detection element 3 includes at least one of a receiving electrode 32 and a transmitting electrode 31;

[0174] The emitter 31 is used to transmit optical signals, and the receiver 32 is used to receive optical signals.

[0175] Optionally, in one implementation of this embodiment, the detection element 3 includes a receiving electrode 32 and an emitting electrode 31, which are arranged side by side along the width direction of the lifting rib body 1.

[0176] In this embodiment, 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.

[0177] Optionally, in one implementation of this embodiment, the detection element 3 includes an ultraviolet sensor or an infrared sensor.

[0178] This implementation method is less likely to damage clothing and the human body, and is highly safe.

[0179] This embodiment also provides a processing cylinder for a garment processing device, including at least one of the above-described lifting ribs.

[0180] In this embodiment, the support plate 2 in the lifting rib can move, so that the detection element 3 on the support plate 2 can move, thereby improving the detection accuracy of the detection element 3 as the position changes, which helps to improve the accuracy of the detection results of the detection element 3.

[0181] 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.

[0182] 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.

[0183] 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:

[0184] The emitter and receiver of the ultraviolet sensor are mounted flat on top of the support plate. Magnets are installed on the side of the support plate, and proximity switches are installed on the lifting rib wall. The push rod motor receives a signal from the main control board and activates to control the rise or fall of the support plate. Three proximity switches are installed on the side wall of the lifting rib, such as... Figures 8-10 As shown, the three proximity switches correspond to the distances d1 (10mm), d2 (15mm), and d3 (20mm) between the ultraviolet sensor and the top of the lifting rib (i.e., the first wall).

[0185] Initially, the proximity switch and magnet are in an off state. When the ultraviolet sensor moves to the distance where the proximity switch and magnet are connected, it proves that the distance between the ultraviolet sensor and the top of the lifting rib is d1 (10mm), d2 (15mm), or d3 (20mm).

[0186] The machine operates as follows: When the user places clothes into the washing machine drum, the drive motor detects the motor current to confirm a load inside the drum. The main control board sends a signal to the gear motor inside the lifting ribs. A lead screw then raises or lowers the support plate of the ultraviolet (UV) sensor, adjusting it to the position where the proximity switch and magnet are activated. The UV sensor then begins to detect and identify the material of the clothes inside the drum, determining if the current distance is suitable. If the current distance is not optimal, the gear motor continues to push the UV sensor, activating the proximity switch and magnet, until the parameters measured by the UV sensor are optimal. After identifying the material of one type of clothing, the main control board controls the drum to rotate, causing the clothes inside to tumble and allowing the UV sensor to identify more clothes. The gear motor then moves to raise or lower the UV sensor, ensuring the sensor is at the optimal testing distance for different materials.

[0187] The following section provides a structural description in conjunction with the parts:

[0188] The lifting rib includes the following components: upper cover (i.e., raised wall), lower cover, transparent cover (i.e., light-transmitting plate), DC motor, gear screw, support plate, emitter and receiver of ultraviolet sensor, magnet, and proximity switch.

[0189] The following assembly relationships are explained:

[0190] The top cover is fitted with a transparent cover, which is installed directly above the emitter and receiver of the ultraviolet sensor.

[0191] The lifting rib contains a DC motor with a coaxial gear. A motor cover is installed below the motor to fix it in place.

[0192] A lead screw with a gear is installed in front of the DC motor, which works in conjunction with the gears on the motor to move.

[0193] A support plate is installed below the lead screw, and moves in conjunction with the lead screw.

[0194] The emitter and receiver of an ultraviolet sensor are mounted on the top of the support plate, and the emitter and receiver move synchronously with the support plate.

[0195] Magnets are installed on the side of the support plate to work with proximity switches for detection.

[0196] There are 3 sets of proximity switches, which are installed in parallel with distances d1, d2 and d3 on the wall of the mounting groove in the lifting rib.

[0197] The bottom cover serves to secure the internal components of the lifting ribs and is fixed to the inner drum of the washing machine.

[0198] Explanation of how to enable the ultraviolet sensor to move inside the lifting rib:

[0199] The main control board powers a DC motor, causing the motor rotor to rotate. This rotor drives the output shaft, which in turn rotates the gears on the output shaft, which in turn drive the lead screw's gears. The lead screw then rotates in a specific direction. As the lead screw rotates, the support plate on it rises or falls according to the direction of rotation. When the lead screw rotates counter-clockwise, the support plate rises; when it rotates clockwise, it falls. Simultaneously, the magnets on the side of the support plate activate three proximity switches. By observing which of the three proximity switches activates, the specific positions of the UV sensor's emitter and receiver can be determined, thus determining the distance between the UV sensor and the first wall. The top proximity switch corresponds to distance d1 (10mm), the middle one to d2 (15mm), and the bottom one to d3 (20mm). Different materials require different testing distances with the UV sensor, and the material of the inner garment is detected by diffuse reflection after the UV sensor is powered on.

[0200] The DC motor has forward and reverse rotation control functions, which are achieved through different wiring methods and circuits. When rotating forward, the gear on the corresponding output shaft rotates clockwise, and when rotating in reverse, the gear on the corresponding output shaft rotates counterclockwise. When the gear on the motor rotates clockwise, it controls the lead screw gear to rotate counterclockwise, thereby raising the lifting platform. When the gear on the motor rotates counterclockwise, it controls the lead screw gear to rotate clockwise, thereby lowering the lifting platform.

[0201] 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.
