[0057] Background Introduction

[0058] Clothing treatment equipment is an indispensable equipment in daily life, which can perform operations such as injecting washing, dehydration, drying, and care on clothes, greatly improving the convenience of clothing treatment. With the development of technology and the improvement of user requirements, the processing accuracy of clothing treatment equipment for clothes has also been improved. Taking washing machines as an example, current washing machines usually identify the material of clothes before processing the clothes, so that different materials of clothes can adopt different processing parameters, which helps to improve the processing effect of clothes.

[0059] Most current washing machines detect the material of clothes in the treatment drum of the clothing treatment equipment by installing detection instruments. However, it is found in actual use that most detection instruments are restricted by their installation positions, resulting in difficult accurate detection of clothes in the treatment drum in some cases, thus reducing the accuracy of detection results.

[0060] Specifically, as Figure 1 and Figure 2 shown, in the first aspect of the embodiments of the present application, a method for detecting clothing material is provided. The method for detecting clothing material includes:

[0061] Obtaining a plurality of parameter values collected by a detection piece in the current detection state, where the detection state includes the detection distance of the detection piece, the parameter values are used to characterize the clothing material, the parameter values are determined according to the optical signals collected by the detection piece, and the detection piece is used to collect the optical signals after the clothes in the clothing treatment drum diffusely reflect the incident optical signals;

[0062] Calculate the average value and standard deviation of multiple parameter values, and perform the first clothing material detection according to the comparison result between the average value and the parameter value interval in the current detection state, and according to the comparison result between the standard deviation and the preset standard deviation.

[0063] Perform clothing material identification according to the comparison result between the average value of multiple parameter values and the parameter value interval, and the comparison result between the standard deviation of multiple parameter values and the standard deviation interval, where the parameter value interval corresponds to the clothing material and the current detection state.

[0064] In the embodiment of the present application, the provided clothing material detection method can, during detection, obtain the average value and standard deviation of multiple collected parameter values, and adjust the detection state of the detection piece according to the average value and the standard deviation, so that the detected data can more accurately reflect the clothing material in the clothing treatment cylinder, and thus a targeted washing strategy can be adopted for the clothing according to the detected clothing material to improve the washing effect of the clothing.

[0065] Specifically, by determining whether the average value of multiple parameters falls within the preset average value interval in the current detection state, the calculated average value can be compared with the intervals corresponding to each material, such as cotton, linen, silk, polyester fiber, wool, etc. By determining whether the standard deviation of multiple parameters falls within the preset standard deviation interval, it can be reflected whether the sampled data is stable, and whether it is necessary to re-detect the clothing material can be determined according to the stability program.

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

[0067] Performing the first clothing material detection according to the comparison result between the average value and the preset average value in the current detection state, and according to the comparison result between the standard deviation and the preset standard deviation includes:

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

[0069] If at least one of the average value and the standard deviation is not within the corresponding preset interval range, adjust the detection distance and / or detection angle of the detection piece and re-perform the first clothing material detection.

[0070] That is, when the average value falls within the preset average value range in the current detection state, it indicates that the average value of the data collected this time can correspond to and represent the preset average value range of the specific clothing material. However, it is necessary to further determine the degree of dispersion of the data collected this time to determine whether the obtained data is relatively 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 data collected this time is stable, and the clothing material can be determined according to the degree of data stability or the detection distance of the detection piece can be adjusted.

[0071] If the average value does not fall within the preset average value range in the current detection state, it indicates that the data collected this time does not correspond to and represent the preset average value range of the specific clothing material. Then, it is necessary to adjust the detection state of the detection piece and re-obtain the collected data.

[0072] It should be noted that the detection piece can output parameter values representing the clothing material at different detection positions, and the clothing processing device presets multiple groups of average value range - material correspondence tables, and each detection state of the detection piece corresponds to a group of average value range - material correspondence tables.

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

[0074] The first case is that the average value is not within the range of the preset average value, or

[0075] The second case is that the average value is within the range of the preset average value, but the standard deviation is not within the range of the preset standard deviation.

[0076] That is, when the average value of the collected data is not within the range of the preset average value in the current detection state, at this time, it is necessary to adjust the detection angle of the detection piece.

[0077] When the average value of the collected data is within the range of the preset average value in the current detection state, but the standard deviation of the collected data is not within the range of the preset standard deviation, at this time, it is necessary to adjust the detection distance of the detection piece.

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

[0079] In the first case, adjust the detection angle of the detection piece, re-obtain the average value and the standard deviation of multiple parameter values after the detection angle is adjusted, and perform the first clothing material detection according to the re-obtained average value and standard deviation.

[0080] Further, in the first case, adjust the detection angle of the detection piece, and after the detection angle is adjusted, re-obtain the average value and standard deviation of multiple parameter values, and perform the first clothing material detection according to the re-obtained average value and standard deviation, including:

[0081] Obtain multiple parameter values collected by the detection piece at the current detection angle, and re-calculate the average value and standard deviation of the multiple parameter values, and determine whether the average value is within the 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, then determine whether the standard deviation is within the preset standard deviation interval range;

[0083] If the average value is not within the preset average value interval range at the current detection angle, then re-adjust the detection angle of the detection piece to perform the first clothing material detection.

[0084] Still further, the clothing material detection method further includes:

[0085] After adjusting the detection angle of the detection piece for a preset number of times, if the obtained average value is still not within the preset average value interval range, then adjust the clothing state in the clothing treatment cylinder and re-perform the clothing material detection until the re-obtained average value is within the corresponding preset average value interval range;

[0086] Wherein the method for adjusting the clothing state in the clothing treatment cylinder includes: controlling the clothing treatment cylinder to rotate at a preset rotation rhythm for a first preset duration;

[0087] Wherein the preset rotation rhythm includes the clothing treatment cylinder rotating forward - stopping - rotating backward - stopping.

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

[0089] In the second case, adjust the detection distance of the detection piece, and after the detection distance is adjusted, re-obtain the standard deviation of multiple parameter values, and perform the first clothing material detection according to the re-obtained standard deviation.

[0090] Further, in the second case, performing the first clothing material detection according to the re-obtained standard deviation includes:

[0091] Determine whether the re-obtained standard deviation is within the preset standard deviation interval range;

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

[0093] If the standard deviation is not within the preset standard deviation range, readjust the detection distance of the detector until the newly obtained standard deviation is within the preset standard deviation range.

[0094] In any of the above embodiments, the clothing material detection method further includes:

[0095] After detecting a clothing material in the clothing processing drum, fluff the clothes in the clothing processing drum, perform a second clothing material detection after the clothes are fluffed, and continue to fluff the clothes after detecting the second clothing material to perform a third clothing material detection until the Mth clothing material detection is performed;

[0096] where M≥3.

[0097] Further, in some embodiments, the clothing material detection method further includes:

[0098] When adjusting the detection distance of the detector, control the detector to move towards the clothing side to shorten the detection distance of the detector.

[0099] Further, in some embodiments, the clothing material detection method further includes:

[0100] Adjust the washing strategy according to the detected clothing material.

[0101] To more clearly understand the detection logic of the clothing material detection method in the embodiments of the present application, the following is combined with Figure 2 for specific description:

[0102] Parameter description: Figure 2 Among them, △a corresponds to cotton, △b corresponds to linen, △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 clothing processing 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 (20mm) from the top of the lifting rib, and the sensor starts to collect material detection data of the clothes in the drum.

[0105] Start collecting parameters for the clothes in the drum 10 times, once every 2 seconds. When collecting, the drum does not rotate. Calculate the corresponding average value a from the collected data. Compare the collected data with the average value a, and at the same time calculate the standard deviation S of this set of sampling data. Compare the obtained average value a at this time with the corresponding intervals for various materials, such as cotton, linen, silk, polyester fiber, wool, etc.

[0106] If the average value a falls within the interval corresponding to the material, then start to determine whether the value of the standard deviation S obtained from the standard deviation S of the sample data at this time is within the range of [2, 5]. If the standard deviation falls within the range of [2, 5], it proves that the degree of dispersion of the sampling data this time is small and the data is relatively stable. After the data is stable, adjust the washing parameters, adjust the motor dehydration speed, drying time, etc. to match the tested material. If the standard deviation does not fall within the range of [2, 5], then control the ultraviolet sensor inside the lifting rib through the cooperation of the lead screw and the gear to adjust the distance to d2 (15 mm). After adjusting the distance, calculate the current standard deviation again. Because the interval range of the same material will be different after adjusting the distance, but the main interval ranges of each distance overlap. After adjusting from the original distance d1 (20 mm) to d2 (15 mm), the material parameter interval range becomes larger {for example, when the detection distance is 20 mm, the material parameter of cotton is 100 - 130, and when the detection distance is 15 mm, the material parameter range of cotton will expand by 10 at both the upper and lower limits and become 90 - 140}. Therefore, the standard deviation S calculated in this distance state can also be used. Compare the standard deviation in this state again to see if it can fall within the interval [2, 5]. If the standard deviation in this state can fall within this interval, there is no need to adjust the distance again, which proves that the stability of the sampling data at this time is good and the degree of dispersion is low. If the standard deviation S still does not fall within the range of the interval [2, 5], then the distance of the ultraviolet sensor inside the lifting rib needs to be adjusted to a distance of d3 (10 mm). After adjusting the distance, verify again whether the standard deviation S at this time falls within the range of the interval [2, 5]. Continuously adjust the distance back and forth 3 times later to detect the standard deviation until the S falls within the range of the interval [2, 5], and then the data can be in a stable state. After determining that the data is stable, start to adjust the washing parameters and dehydration speed in combination with the proportion of the tested material parameters. It should be noted that when a clothing material is detected, control the clothing treatment drum to rotate to disperse the clothes in the drum, and re-obtain the clothing material in the clothing treatment drum after dispersion. If it is detected 10 times, the clothes need to be dispersed 9 times. If 8 times are cotton and 2 times are silk, then use the cotton and linen mode combined with the gentle mode for washing.

[0107] The control logic introduced above is for when the average value a falls within the interval corresponding to the material. When the average value a does not fall within the interval range of the corresponding material, the following control logic is adopted: If the average value a does not fall within the interval range of the corresponding material, it is necessary to rotate the driving motor by an angle α (60°) through the main control board to change the angle of the ultraviolet sensor inside the lifting rib. After changing the angle, the material parameters of the clothes in the drum are measured again to determine whether the current average value can fall within the interval ranges (△a--△e) of the preset materials. If it can fall within the preset parameter ranges of each material, then it is further determined whether the standard deviation S is stable within the interval range of [2, 5]. The method for judging and adjusting the standard deviation is the same as that described in the previous paragraph, and it is achieved by adjusting the ultraviolet sensor through the push rod motor. If the average value does not fall within the preset interval ranges of each material, the rotation angle of the drum motor is adjusted again for testing. The cradle wash rotates forward and backward continuously. After rotating for 1 minute, the judgment is made again until the average value can fall within the preset interval range. When both the average value and the standard deviation meet the judgment conditions, the washing mode can be adjusted in combination with the detected material type. For example, if it is detected 10 times, 8 times it is cotton and 2 times it is linen, then the cotton-linen washing mode is directly used. If 8 times it is cotton and 2 times it is wool, the whole machine will prompt an alarm, prompting the user to take out the wool and then run the cotton-linen washing mode. If 6 times it is cotton and 4 times it is chemical fiber, an algorithm combining cotton-linen and chemical fiber is selected to adjust the washing parameters, or AI intelligent washing is performed for washing.

[0108] In an embodiment of the present application, after the optical signal contacts the clothes, diffuse reflection can occur, and thus the diffuse reflection parameter value can be obtained.

[0109] Specifically, the diffuse reflection parameter value can be the parameter value of the reflected optical signal itself after diffuse reflection, such as the wavelength and light intensity of the reflected optical signal, or it can be the parameter value obtained after calculating the parameter value of the reflected optical signal itself. For example, after substituting the wavelength and / or light intensity of the reflected optical signal into a preset calculation formula, the diffuse reflection parameter value is obtained. Generally speaking, as long as different clothing materials can correspond to different diffuse reflection parameter values.

[0110] In an embodiment, the preset calculation formula for calculating the diffuse reflection parameter value can be a formula containing the wavelength and light intensity of the reflected optical signal. For example, the diffuse reflection parameter value a = (wavelength λ - absorbed wavelength △E) / wavelength λ * φ luminous flux * power factor (related to light intensity).

[0111] In an embodiment, in order to determine the material of the clothes, a diffuse reflection standard value interval (that is, the parameter value interval mentioned above) is preset. Different diffuse reflection standard value intervals correspond to different clothing materials. That is to say, there is a corresponding relationship between the diffuse reflection standard value interval and the clothing material.

[0112] Specifically, the diffuse reflection standard value range is a numerical range composed of diffuse reflection standard values. It should be noted that the diffuse reflection standard value and the diffuse reflection parameter value are of the same type or values obtained using the same algorithm. The difference is that the diffuse reflection standard value is the parameter value obtained from a diffuse reflection experiment on clothing when the clothing material is known, while the diffuse reflection parameter value is the parameter value obtained from a diffuse reflection on clothing when actually identifying the clothing material. For ease of understanding, for example, during testing, the wavelength and light intensity of the reflected light signal after diffuse reflection are calculated using formula A to obtain the diffuse reflection standard value. After conducting multiple experiments on clothing of material a, a numerical range P1 can be divided based on all the obtained diffuse reflection standard values. When actually identifying the clothing material, the wavelength and light intensity of the reflected light signal after diffuse reflection are also calculated using formula A, that is, the diffuse reflection parameter value is obtained. Since the calculation process of the diffuse reflection parameter value is the same as that of the diffuse reflection standard value, the clothing material of the clothing can be determined based on the diffuse reflection parameter value.

[0113] The corresponding relationship between the diffuse reflection standard value range and the clothing material is as follows: Each type of clothing material corresponds to a diffuse reflection standard value range, and the diffuse reflection standard value ranges corresponding to different types of clothing materials are different. For example, material a corresponds to the diffuse reflection standard value range P1, and this is the corresponding relationship. When the diffuse reflection parameter value is within P1, it can be determined that the clothing material of the clothing is a.

[0114] In this embodiment, the corresponding relationship between the parameter value range, the clothing material, and the detection state can be obtained through experiments under different detection states (detection distances).

[0115] Furthermore, as Figures 3 - 10 shown, in the second aspect of the embodiment of the present application, a clothing processing device is also provided, which includes the clothing material detection method provided in the first aspect of the embodiment of the present application.

[0116] The clothing processing device herein refers to a device capable of processing loads such as clothing. Among them, in addition to clothing, the load can also be items such as trousers, shoes, hats, etc. that have the same processing requirements as clothing. In this embodiment, they are uniformly referred to as clothing. Among them, processing includes washing, drying, nursing, etc. Common clothing processing devices include, for example, washing machines, dryers, clothing care machines, etc.

[0117] The lifting rib refers to a structure in the processing cylinder that is used to contact the clothing, collide with and rub against the clothing, or is used to change the distribution of the clothing.

[0118] Clothing treatment equipment is an indispensable equipment in daily life. It can perform operations such as injecting washing, dehydration, drying, and caring on clothes, greatly improving the convenience of clothing treatment. With the development of technology and the improvement of user requirements, the treatment accuracy of clothing treatment equipment for clothes has also been improved. Taking a washing machine as an example, current washing machines usually identify the material of clothes before processing the clothes, so that clothes of different materials can adopt different processing parameters, which helps to improve the treatment effect of clothes.

[0119] Most current washing machines detect the material of clothes in the treatment cylinder of the clothing treatment equipment by installing detection instruments. However, it is found in actual use that most detection instruments are restricted by their installation positions, resulting in difficulty in accurately detecting the clothes in the treatment cylinder in some cases, thus reducing the accuracy of the detection results.

[0120] Based on this, the embodiment of the present application first provides a lifting rib. Taking the application of this lifting rib on the treatment cylinder of the clothing treatment equipment as an example, referring to Figures 3 - 10 the structural schematic diagram of the lifting rib shown, the lifting rib includes a lifting rib body 1 and a support plate 2;

[0121] The lifting rib body 1 has: a convex wall 11 protruding from the inner wall of the treatment cylinder towards the inside of the treatment cylinder, and an installation space formed inside the convex wall 11;

[0122] The support plate 2 is movably arranged in the installation space, and a detection piece 3 for performing optical signal detection is arranged on the support plate 2;

[0123] Among them, at least the part of the convex wall 11 opposite to the detection piece 3 has a light-transmitting part for the detection piece 3 to perform optical signal detection.

[0124] The lifting rib body 1 can be one or more. The lifting rib body 1 can be arranged at the bottom of the treatment cylinder or on the inner wall of the treatment cylinder. The present embodiment does not make specific limitations on this.

[0125] The outer contour of the lifting rib body 1 can be a shape similar to a triangle, a quadrilateral or a star. The present embodiment does not make specific limitations on this.

[0126] In an application scenario, the inner wall of the clothing treatment cylinder includes the bottom and the side wall of the treatment cylinder. The part opposite to the opening of the treatment cylinder is the bottom, and the part located between the bottom and the opening and surrounding a circle is the side wall. Preferably, if the opening direction of the treatment cylinder faces upward of the clothing treatment equipment, the lifting rib body 1 is arranged at the bottom of the treatment cylinder, and the lifting rib body 1 extends towards the direction of the opening to form the convex wall 11. If the opening direction of the treatment cylinder faces forward of the clothing treatment equipment, the lifting rib body 1 is arranged on the side wall of the treatment cylinder, and the lifting rib body 1 extends upward of the clothing treatment equipment to form the convex wall 11.

[0127] For the sake of easy understanding, the extending 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 arranged at the bottom of the cylinder, the radial direction of the processing cylinder is taken as the length direction of the lifting rib body 1, and the direction perpendicular to its length direction in the horizontal plane of the lifting rib body 1 is the width direction; if the lifting rib body 1 is arranged 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] An installation space is formed inside the convex wall 11. The installation space and the inside of the processing cylinder can be two non - communicating spaces or communicating spaces. This embodiment does not make specific limitations on this. The support plate 2 is located in the installation space and can move. The support plate 2 can move along the height direction of the lifting rib body 1 or along the width direction of the lifting rib body 1. It should be noted that the support plate 2 is movably arranged in the installation space, specifically, the support plate 2 is reciprocally movably arranged in the installation space. Preferably, the support plate 2 can reciprocally move along the height direction of the lifting rib body 1 in the installation space, so as to drive the detection piece 3 to reciprocally move along the height direction of the lifting rib body 1.

[0129] The light - transmitting part refers to the part on the convex wall 11 that can transmit light. Therefore, the light - transmitting part can be a space without physical structure obstruction, such as a through - hole, a through - groove, etc., or a physical structure with light - transmitting properties, such as a plate on the convex wall 11 that can transmit light. It should be noted that the light - transmitting part needs to be opposite to the detection piece 3. However, since the detection piece 3 can move with the support plate 2, at any position of the moving track of the detection piece 3, there is a corresponding light - transmitting part, so that when the detection piece 3 performs optical signal detection, the light - transmitting part can be used to transmit the optical signal into the processing cylinder or receive the optical signal transmitted from the inside of the processing cylinder into the installation space.

[0130] Adopting this embodiment, a movable support plate 2 is arranged in the lifting rib body 1, and a detection piece 3 is arranged on the support plate 2, so that the position of the detection piece 3 can change with the movement of the support plate 2, thereby enabling the detection accuracy of the detection piece 3 to be improved with the change of position, which helps to improve the accuracy of the detection result of the detection piece 3.

[0131] In a possible embodiment of the present 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 towards the inner wall of the processing cylinder;

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

[0133] Among them, the extending direction of the first wall 111 is parallel to the width direction or the length direction of the lifting rib body 1, and the extending direction of the second wall 112 is parallel to the height direction of the lifting rib body 1. It should be noted that the so-called parallel in this embodiment does not require the two directions to be completely parallel, and an included angle is also allowed, as long as the two directions are not perpendicular.

[0134] Based on the description of the extending directions of the first wall 111 and the second wall 112, it can be known that the second wall 112 is actually a wall that encloses a closed space.

[0135] Adopting this embodiment, the second wall 112 is integrally formed or hermetically connected with the processing cylinder, which is convenient for the production or connection of the processing cylinder and the lifting rib body 1, and improves the manufacturing convenience or installation convenience of the lifting rib.

[0136] Optionally, in an implementation manner 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 towards the inner wall of the processing cylinder;

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

[0138] The difference from the previous embodiment is that the convex wall 11 in this embodiment has a lower cover 12, and the lower cover 12 is detachably connected to the second wall 112, so that the convex wall 11 and the processing cylinder are two independently produced components. When it is necessary to set the lifting rib in the processing cylinder, the lower cover 12 can be first fixedly arranged on the inner wall of the processing cylinder, and then the convex wall 11 can be connected to the lower cover 12. Among them, the lower cover 12 and the inner wall of the processing cylinder can be welded, integrally formed, or detachably connected; the convex wall 11 and the lower cover 12 can be detachably connected through structures such as screws and buckles.

[0139] Adopting this embodiment, by setting the lower cover 12, the installation method between the lifting rib body 1 and the processing cylinder becomes flexible, and the connection convenience between the lifting rib and the processing cylinder is improved. In addition, the lower cover 12 is detachably connected to the second wall 112, which is convenient for replacing 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 repair.

[0140] Optionally, in an implementation manner of this embodiment, the lifting rib further includes a driving component 4, and the driving component 4 is arranged in the installation space;

[0141] The driving component 4 is drivingly connected to the support plate 2 to drive the support plate 2 to approach or move away from the light-transmitting part.

[0142] Among them, the driving component 4 refers to a component with driving ability. 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 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 an application scenario, the light-transmitting part is located on the first wall 111. 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 when the support plate 2 moves, it approaches or moves away from the light-transmitting part.

[0144] Adopting this embodiment, the driving component 4 can drive the support plate 2 to move, improving the convenience and stability of controlling the movement of the support plate 2. The driving component 4 is arranged in the installation space, which is beneficial to protecting the driving component 4, making the driving component 4 not easily get water, prolonging the service life of the driving component 4, and at the same time also helping to avoid the driving component 4 contacting with clothes and getting entangled.

[0145] Optionally, in an implementation manner of this embodiment, the driving component 4 includes a driver 41 and a transmission member 42. The input end of the transmission member 42 is connected to the output shaft of the driver 41, and the output end of the transmission member 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 generates an action, thereby driving the transmission member 42 connected to the output shaft to act. The action of the transmission member 42 drives the support plate 2 to act, realizing the driving effect on the support plate 2.

[0147] Among them, the functions of the transmission member 42 include but are not limited to changing the direction of the driving force, the magnitude of the driving force, and the driving form. Specifically, the driving form is, for example, changing linear motion into rotational motion or changing rotational motion into linear motion.

[0148] Adopting this embodiment, by setting the transmission member 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 member 42, and on the other hand, it helps to correct the driving force of the driver 41 by relying on the transmission member 42, such as correcting the direction and / or magnitude of the driving force, etc.

[0149] Optionally, in an implementation manner of this embodiment, the driver 41 is a motor and is installed in the installation space through a motor gland 43;

[0150] The transmission member 42 includes a first gear 421, a lead screw 422, and a second gear 423 arranged at one end of the lead screw. Among them, the first gear 421 is arranged on the output shaft of the motor, one end of the lead screw 422 is in transmission connection with the first gear 421 through the second gear 423, and the other end of the lead screw is rotatably connected 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 support plate 2 through the threaded hole 21.

[0152] In an application scenario, the motor is a rotary type motor, that is, after the motor is started, the output shaft of the motor makes a rotary motion. The first gear 421 rotates following the output shaft and drives the second gear 423 to rotate at the same time. Among them, the sizes, number of teeth, and pitch of the first gear 421 and the second gear 423 can be the same or different. When they are different, the rotation speed of the second gear 423 is different from that of the first gear 421, realizing the adjustment of the rotation speed. The lead screw 422 rotates under the drive of the second gear 423, causing the support plate 2 threadedly connected to the lead screw 422 to move along the height direction of the lead screw 422.

[0153] Adopting this embodiment, the first gear 421, the lead screw 422, and the second gear 423 have high stability, which helps to improve the stability of the movement of the support plate 2. In addition, when the sizes of the first gear 421 and the second gear 423 are different, the movement speed transmitted to the support plate 2 will also be different, which is beneficial to adjusting the movement speed of the support plate 2.

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

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

[0156] When the proximity switch 5 is triggered, an electrical signal can be generated. Relying on the electrical signal, the movement of the support plate 2 can be controlled, so that the proximity switch 5 can be used to automatically control the support plate 2 to stop moving or start moving. Preferably, when the proximity switch 5 is triggered, an electrical signal for controlling the support plate 2 to stop moving is generated. Specifically, the electrical signal generated by the proximity switch 5 is used to control the braking of the motor, so that the support plate 2 stops moving.

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

[0158] Optionally, in an implementation manner of this embodiment, a plurality of proximity switches 5 are arranged along the moving direction of the support plate 2.

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

[0160] Adopting this embodiment enables multiple proximity switches 5 to be used to set multiple stopping points for the support plate 2, improving the control accuracy and convenience of the support plate 2.

[0161] Optionally, in an implementation manner of this embodiment, an installation groove 6 extending towards the inner wall of the processing cylinder is formed on the first wall 111. The groove wall of the installation groove 6 and the second wall 112 form a receiving space. The installation space includes the installation groove 6 and the receiving space, and the installation groove 6 communicates with the receiving space;

[0162] The support plate 2 is located in the installation groove 6 and moves in the installation groove 6. The driving component 4 is located in the receiving space, and the proximity switch 5 is arranged on the groove wall of the installation groove 6.

[0163] Forming the installation groove 6 on the first wall 111 will form a groove wall on the outer peripheral side in the extending 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 notch of the installation groove 6 is formed on the first wall 111, and this notch is the light-transmitting part. When the optical signal is transmitted, it can pass through the notch and enter or leave the installation groove 6.

[0165] Adopting this embodiment, by forming the installation groove 6, the support plate 2 can move in the installation groove 6, which is convenient for the detection part 3 on the support plate 2 to detect the optical signal. The groove wall formed by the installation groove 6 installs the proximity switch 5, making the proximity switch 5 easy to install and close to the support plate 2, improving the accuracy of the proximity switch 5 being triggered. The installation space is divided into the installation groove 6 and the receiving space. Since the receiving space is between the first wall 111, the groove wall of the installation groove 6 and the second wall 112, the driving component 4 in the receiving space is not easily interfered by the outside of the receiving space, improving the operation stability of the driving component 4.

[0166] Optionally, in an implementation manner of this embodiment, the installation groove 6 penetrates through the second wall 112 along the width direction of the lifting rib body 1.

[0167] Adopting this embodiment can increase the propagation area of the optical signal and improve the detection accuracy of the detection part 3.

[0168] Optionally, in an implementation manner of this embodiment, the lifting rib further includes a groove sealing plate 7. The groove sealing plate 7 is connected to the first wall 111 and the second wall 112 and is used to seal the installation groove 6;

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

[0170] A light-transmitting part is formed at the position corresponding to the groove sealing plate 7.

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

[0172] Adopting this embodiment makes it difficult for clothes or water to enter the receiving groove and thus difficult to enter the receiving space, protecting parts such as the detection part 3, the support plate 2, the proximity switch 5, and the driving component 4, and improving their service life.

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

[0174] The transmitting electrode 31 is used to emit an optical signal, and the receiving electrode 32 is used to receive an optical signal.

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

[0176] Adopting this embodiment, the receiving electrode 32 and the transmitting electrode 31 arranged side by side are conducive to detecting clothes by relying on diffuse reflection.

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

[0178] Adopting this implementation method is not likely to cause damage to clothes and the human body, and has high safety.

[0179] This embodiment also provides a processing cylinder of a clothing treatment device, including at least one of the above-mentioned lifting ribs.

[0180] Adopting this embodiment, the support plate 2 in the lifting rib can move, so that the detection member 3 on the support plate 2 can move, thereby enabling the detection accuracy of the detection member 3 to be improved as the position changes, which helps to improve the accuracy of the detection result of the detection member 3.

[0181] This embodiment also provides a clothing treatment device, including at least one of the above-mentioned lifting ribs or at least one of the above-mentioned processing cylinders.

[0182] In the above embodiments of the present application, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments. The steps shown in the relevant flowcharts can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here. In other words, the step order described in the previous embodiments is only an example, and a reasonable adjustment of the step order based on the content of the embodiments of the present application is also within the protection scope of the embodiments of the present application.

[0183] In a specific implementation of the embodiments of the present application, the clothing treatment device in the above embodiments is a washing machine, the processing cylinder is a cylinder in the washing machine for processing clothes, and the detection member in the lifting rib is an ultraviolet sensor. The structure and use process of the lifting rib arranged in the washing machine cylinder include:

[0184] The emitter and receiver of the ultraviolet sensor are installed flat above the support plate. A magnet is installed on the side of the support plate, and a proximity switch is installed on the wall of the lifting rib. The push rod motor receives the signal from the main control board and powers on to control the lifting or lowering of the support plate. Three proximity switches are respectively installed on the side wall of the lifting rib. As Figures 8 - 10 shown, the three proximity switches respectively correspond to the distances d1 (10 mm), d2 (15 mm), and d3 (20 mm) of the ultraviolet sensor from the top of the lifting rib (i.e., the first wall).

[0185] At the beginning, the proximity switch and the magnet are in a disconnected state. When the ultraviolet sensor moves to the distance where the proximity switch and the magnet are connected, it proves that the distance d1 (10 mm), d2 (15 mm), or d3 (20 mm) of the ultraviolet sensor from the top of the lifting rib.

[0186] For the whole machine control, after the user puts the clothes into the washing machine drum, the drive motor detects the motor current to determine that there is a load in the drum. The main control board sends a signal to the gear motor inside the lifting rib, and uses the lead screw to lift or lower the support plate of the ultraviolet sensor, and adjusts it to the position where the proximity switch and the magnet are conducting. Then, combined with the ultraviolet sensor, it starts to detect and identify the material of the clothes in the drum to determine what kind of material it is, and judges whether the current distance is appropriate. If the current distance is not the most appropriate distance, the gear motor continues to push the ultraviolet sensor, and the proximity switch and the magnet judge to be connected until the parameters measured by the ultraviolet sensor are the most appropriate parameters, then the current test distance of the ultraviolet sensor is appropriate. After identifying the material of one piece of clothing, the main control board controls the rotation of the drum to make the clothes in the drum tumble, so that the ultraviolet sensor can identify more clothes. The gear motor starts to act to push the ultraviolet sensor up or down to make the ultraviolet sensor at the best test distance when testing different materials.

[0187] The following is an elaboration of the structure in combination with the parts:

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

[0189] The following is an explanation of the assembly relationship:

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

[0191] A DC motor is installed inside the lifting rib. The DC motor is coaxially linked with a gear, and a motor gland is installed below the motor to fix the motor.

[0192] A gear lead screw is installed in front of the DC motor and is engaged with the gear on the motor.

[0193] A support plate is installed below the gear screw rod and moves in cooperation with the gear screw rod.

[0194] The emitter and receiver of the ultraviolet sensor are installed above the support plate, and the emitter and receiver move synchronously with the support plate.

[0195] A magnet is installed on the side of the support plate for cooperation with the proximity switch for detection.

[0196] There are 3 groups of proximity switches, which are installed side by side on the groove wall of the installation groove in the lifting rib in cooperation with the distances d1, d2, and d3.

[0197] The lower cover serves to fix the components inside the lifting rib and is fixed to the inner cylinder of the washing machine.

[0198] Explanation of the movement of the ultraviolet sensor inside the lifting rib:

[0199] The main control board supplies power to the DC motor. The rotor of the DC motor rotates, and the rotor drives the output shaft to rotate. After the output shaft rotates, the gear on the output shaft starts to rotate, which drives the gear of the screw rod to rotate. After the gear of the screw rod rotates, the screw rod also starts to rotate in a certain direction. After the screw rod rotates, the support plate on the screw rod rises or falls according to the rotation direction of the screw rod. When the screw rod rotates counterclockwise, the support plate on the screw rod starts to rise. When the screw rod rotates clockwise, the support plate on the screw rod starts to fall. While the support plate is rising or falling, combined with the magnet on the side of the support plate, when the magnet runs to the positions of the 3 groups of proximity switches, the corresponding proximity switch conducts. After observing which of the 3 groups of proximity switches conducts, the specific positions of the emitter and receiver of the ultraviolet sensor can be determined, and then the distance between the ultraviolet sensor and the first wall can be determined. The uppermost proximity switch corresponds to the distance d1 (10 mm), the middle proximity switch corresponds to the distance d2 (15 mm), and the lowermost proximity switch corresponds to the distance d3 (20 mm). Considering that different test distances are required for different materials when testing with the ultraviolet sensor, and after the ultraviolet is powered on, the material of the clothes in the drum is detected through diffuse reflection.

[0200] The DC motor has the function of forward and reverse rotation control, which is 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 gear of the screw rod to rotate counterclockwise to achieve the rise of the lifting platform. When the gear on the motor rotates counterclockwise, it controls the gear of the screw rod to rotate clockwise to achieve the descent of the lifting platform.

For parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments. The steps shown in the relevant flowcharts can be executed in a computer system such as a set of computer-executable instructions.
