TECHNICAL FIELD

[0001] The present application belongs to the technical field of clothes processing, and specifically provides a control method for a clothes processing device and the clothes processing device. BACKGROUND

[0002] With the improvement of people's living standards, clothes processing devices such as washing machines and washing-drying integrated machines have entered thousands of households and have become an essential household appliance in people's daily life.

[0003] In the prior art, the door seal structure of the clothes processing device includes a window pad, which is generally installed on the outer drum and is fixedly connected with the outer drum through a clamping groove and a fastener. One or more clothes blocking corners are usually arranged on the window pad, which are used to block the clothes in the inner drum from entering between the observation window glass and the window pad during the washing or drying of the clothes.

[0004] The current clothes processing device usually selects a corresponding washing mode according to the weight of the clothes and performs washing according to the initial washing parameters of the washing mode. However, for some clothes with small weight but large volume (such as a rug, a blanket, a down quilt, etc.), the clothes are prone to collide with the clothes blocking corner during washing, and long-time washing can easily damage the clothes.

[0005] Therefore, there is a need in the art for a new technical solution to solve the above technical problems. SUMMARY

[0006] The present application aims to solve the above technical problems, i.e., to solve the problem that the existing clothes with small weight and large volume are prone to collide with the clothes blocking corner during washing and are damaged.

[0008] In the above preferred technical scheme of the control method for the laundry treating apparatus, the step of "selectively causing the laundry treating apparatus to execute a washing mode or a collision detection mode according to the weight and the volume, and selectively adjusting initial washing parameters of the washing mode according to an execution result of the collision detection mode" specifically includes: comparing the weight with a set weight; comparing the volume with a set volume; and selectively causing the laundry treating apparatus to execute a washing mode or a collision detection mode according to the comparison result, and selectively adjusting initial washing parameters of the washing mode according to an execution result of the collision detection mode.

[0009] In the above preferred technical scheme of the control method for the laundry treating apparatus, the step of "selectively causing the laundry treating apparatus to execute a washing mode or a collision detection mode according to the comparison result, and selectively adjusting initial washing parameters of the washing mode according to an execution result of the collision detection mode" specifically includes: causing the laundry treating apparatus to execute a washing mode if the weight is not less than the set weight or the volume is not greater than the set volume; and causing the laundry treating apparatus to execute a collision detection mode and selectively adjusting initial washing parameters of the washing mode according to an execution result of the collision detection mode if the weight is less than the set weight and the volume is greater than the set volume.

[0010] In the above preferred technical scheme of the control method for the laundry treating apparatus, the step of "causing the laundry treating apparatus to execute a collision detection mode and selectively adjusting initial washing parameters of the washing mode according to an execution result of the collision detection mode" specifically includes: causing the laundry treating apparatus to execute a collision detection mode to obtain a collision parameter; and selectively adjusting initial washing parameters of the washing mode according to the collision parameter.

[0011] In the above preferred technical scheme of the control method for the laundry treating apparatus, the step of "causing the laundry treating apparatus to execute a collision detection mode to obtain a collision parameter" specifically includes: causing the inner tub to rotate at an initial washing rotational speed of the washing mode for a set time; obtaining a video of the inner tub during the rotation; and determining a collision parameter of the laundry according to the video.

[0012] In the above preferred technical scheme of the control method for the laundry treating apparatus, the step of "selectively adjusting initial washing parameters of the washing mode according to the collision parameter" specifically includes: determining a risk level of the laundry according to the collision parameter; and selectively adjusting initial washing parameters of the washing mode according to the risk level.

[0013] In the above preferred technical scheme of the control method for the laundry treating apparatus, the collision parameter includes a collision frequency and a collision area ratio.

[0014] In the preferred technical solution of the control method for the laundry treating apparatus, the step of "selectively adjusting the initial washing parameter of the washing mode according to the risk level" specifically comprises: if the risk level is level 0, not adjusting the initial washing parameter of the washing mode; and if the risk level is not level 0, adjusting the initial washing parameter of the washing mode.

[0015] In the preferred technical solution of the control method for the laundry treating apparatus, the step of "adjusting the initial washing parameter of the washing mode" specifically comprises: obtaining an adjustment parameter corresponding to the risk level; and adjusting the initial washing parameter of the washing mode according to the adjustment parameter.

[0016] In the preferred technical solution of the control method for the laundry treating apparatus, the step of "obtaining the volume of the laundry after being soaked" specifically comprises: obtaining an image of the laundry after being soaked; and determining the volume of the laundry after being soaked according to the image.

[0017] In the second aspect, the present application provides a laundry treating apparatus, which comprises a controller and is configured to execute the control method described above.

[0018] With the above technical solution, the control method for the laundry treating apparatus provided by the present application obtains the weight of the laundry in the inner tub and the volume of the laundry after being soaked, selectively causes the laundry treating apparatus to execute the washing mode or the anti-collision detection mode according to the weight and the volume, and selectively adjusts the initial washing parameter of the washing mode according to the execution result of the anti-collision detection mode. With such a setting mode, whether the laundry is likely to be damaged is determined by the weight and the volume, and then the laundry treating apparatus is caused to directly execute the washing mode or execute the anti-collision detection mode according to the determination result. In the case where the laundry treating apparatus is caused to execute the anti-collision detection mode, the initial washing parameter of the washing mode is selectively adjusted according to the result of the anti-collision detection, so that the adjusted initial washing parameter is more in line with the current state of the laundry, thereby reducing the probability of the laundry colliding with the laundry blocking corner in the washing process and further avoiding the laundry from being damaged in the washing process.

[0019] Further, the weight is compared with the set weight, the volume is compared with the set volume, and according to the two comparison results, the laundry treating apparatus is selectively caused to execute the washing mode or the collision detection mode and the initial washing parameter of the washing mode is selectively adjusted according to the execution result of the collision detection mode, and in this way, the execution of the washing mode or the collision detection mode is determined according to the two comparison results of the weight and the volume, and the accuracy of the determination is improved.

[0020] Further, in the case that the weight is not less than the set weight or the volume is not greater than the set volume, the laundry is not damaged, and thus the laundry treating apparatus directly executes the washing mode to wash the laundry, and only in the case that the weight is less than the set weight and the volume is greater than the set volume, the laundry is damaged, and thus the laundry treating apparatus executes the collision detection mode and further selectively adjusts the initial washing parameter of the washing mode according to the execution result of the collision detection mode to reduce the probability of damage of the laundry in the washing process.

[0021] Further, the laundry treating apparatus is caused to execute the collision detection mode to obtain the collision parameter, and the initial washing parameter of the washing mode is selectively adjusted according to the collision parameter, and in this way, the collision parameter is obtained when the laundry treating apparatus executes the collision detection mode, and then whether the initial washing parameter of the washing mode needs to be adjusted is determined according to the collision parameter, and thus the probability of damage of the laundry in the washing process is reduced.

[0022] Further, the step of causing the laundry treating apparatus to execute the collision detection mode to obtain the collision parameter specifically includes causing the inner tub to rotate at the initial washing rotational speed of the washing mode for a set time, obtaining a video of the inner tub in the rotating process, and determining the collision parameter of the laundry according to the video, and in this way, the washing process of the laundry is simulated, and the collision parameter of the laundry is determined according to the video in the washing process, and the result is accurate.

[0023] Further, the step of selectively adjusting the initial washing parameter of the washing mode according to the collision parameter specifically includes determining the risk level of the laundry according to the collision parameter, and selectively adjusting the initial washing parameter of the washing mode according to the risk level, and in this way, the risk level of the laundry is determined according to the collision parameter first, and then whether the initial washing parameter of the washing mode needs to be adjusted is determined according to the risk level, and the determination is convenient.

[0024] Further, when the risk level is 0, it indicates that the laundry has no damage risk, and thus the initial washing parameter of the washing mode is not adjusted, and when the risk level is not 0, it indicates that the laundry has a damage risk, and thus the initial washing parameter of the washing mode needs to be adjusted according to the risk level.

[0030] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] Those skilled in the art should understand that although the steps of the control method of the present invention are described in a specific order in this application, this order is not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in different orders. For example, the execution order of steps S1000 and S2000 of the control method of the present invention can be interchanged, or steps S1000 and S2000 can be performed simultaneously.

[0032] As mentioned in the background art, lightweight but bulky garments are prone to collision with the corner protectors during washing, resulting in damage. The control method for garment handling equipment of the present invention determines the probability of garment damage based on weight and volume, thereby deciding whether to execute the washing mode directly or to execute an anti-collision detection mode. Based on the detection results, the initial washing parameters of the washing mode are selectively adjusted to reduce the probability of garment damage during washing.

[0033] Specifically, the garment processing device of the present invention includes a controller, a housing, and an outer cylinder, an inner cylinder, a cylinder door, a window pad, and a garment guard installed inside the housing. The controller is used to control the operation of the garment processing device, and the controller is configured to execute the control method of the present invention.

[0034] The inner cylinder is rotatably installed inside the outer cylinder, the cylinder door is pivotally connected with the shell and can open and close the outer cylinder, the window pad is installed on the outer cylinder and is used for sealing the gap between the cylinder door and the outer cylinder, and the clothes corner is installed on the window pad and is used for resisting the clothes in the inner cylinder from entering between the window pad and the cylinder door.

[0035] It should be noted that the clothes treatment equipment of the present application is specifically an equipment capable of washing clothes, including but not limited to a drum washing machine, a washing and protecting integrated machine and a washing and drying integrated machine.

[0036] Specifically, as shown in Figure 1 The control method for the clothes treatment equipment of the present application comprises the following steps:

[0037] S1000: obtaining the weight of the clothes in the inner cylinder.

[0038] The clothes in the inner cylinder that need to be washed are weighed, so as to obtain the weight of the clothes in the inner cylinder, in order to execute step S3000.

[0039] Specifically, the weight of the clothes in the present application is specifically the weight of the dry clothes before water is added.

[0040] Specifically, the clothes treatment equipment of the present application is provided with a weighing device, which can weigh the clothes in the inner cylinder, so as to obtain the weight of the clothes, and the weighing device is in communication connection with the controller and can transmit the weight data obtained by weighing to the controller.

[0041] Specifically, the weighing device is a weight sensor, which is installed below the inner cylinder and can weigh the inner cylinder, wherein the weight of the clothes in the inner cylinder is the total weight of the inner cylinder and the clothes minus the weight of the inner cylinder.

[0042] S2000: obtaining the volume of the clothes after water absorption.

[0043] The volume of the clothes after water absorption is obtained, in order to execute step S3000.

[0044] It should be noted that the volume of the clothes after water absorption in the present application is specifically the volume of the clothes after water absorption before formal washing. Since the volume occupied by part of the clothes will change after water absorption, the volume of the clothes after water absorption is closer to the volume of the clothes in the washing process, so that the volume of the clothes after water absorption is obtained and subsequent judgment is made according to the volume, so that the determination result is more accurate.

[0045] It should also be noted that the present application does not make any limitation on the specific way of obtaining the volume of the clothes after water absorption, as long as the volume of the clothes after water absorption can be obtained in time after the clothes absorb water.

[0046] Exemplarily, an image of the clothes after water absorption can be acquired first, and then the volume of the clothes after water absorption can be determined according to the image.

[0047] S3000: According to the weight and the volume, selectively causing the clothes processing device to execute a washing mode or a collision avoidance detection mode and selectively adjusting initial washing parameters of the washing mode according to an execution result of the collision avoidance detection mode.

[0048] After the weight of the clothes and the volume of the clothes after water absorption are acquired, whether the clothes have a possibility of being damaged is determined according to the weight and the volume. If the clothes will not be damaged in the washing process, the clothes processing device is caused to execute the washing mode, so that washing is directly performed according to the initial washing parameters of the washing mode. If the clothes can be damaged in the washing process, the clothes processing device is caused to execute the collision avoidance detection mode, and according to the execution result of the collision avoidance detection mode, the initial washing parameters of the washing mode are selectively adjusted, so as to reduce the probability of collision between the clothes and the clothes baffle in the washing process, thereby avoiding the clothes from being damaged in the washing process.

[0049] The washing mode can be a washing program selected by a user according to the number and material of the clothes through a control panel of the clothes processing device, or can be a washing program automatically determined by the clothes processing device according to the weight of the clothes.

[0050] Exemplarily, each washing program corresponds to a set of initial washing parameters, and when the clothes processing device executes the washing program, the clothes are washed according to the initial washing parameters. The washing parameters include but are not limited to washing rotation speed, washing rotation stop ratio, washing time, dehydration rotation speed and dehydration time.

[0051] Exemplarily, each washing program corresponds to a set of initial washing parameters, and when the clothes processing device executes the washing program, the clothes are washed according to the initial washing parameters. The washing parameters include but are not limited to washing rotation speed, washing rotation stop ratio, washing time, dehydration rotation speed and dehydration time.

[0052] The control method of the clothes processing device will be described in detail below with reference to a specific embodiment.

[0053] Embodiment

[0054] As shown in Figure 2 The control method of the clothes processing device of the embodiment includes the following steps:

[0055] S1000: Acquire the weight of the clothes in the inner drum.

[0056] The clothes in the inner drum are weighed to obtain the weight of the clothes in the inner drum, so as to perform step S3000. The weight of the clothes is the weight of the dry clothes before water is added.

[0057] Specifically, the laundry treating apparatus of the present application is provided with a weight sensor, which is installed below the inner drum and can weigh the inner drum, wherein the weight of the clothes in the inner drum is the total weight of the inner drum and the clothes minus the weight of the inner drum. The weight sensor is in communication connection with the controller and can transmit the weight data obtained by weighing to the controller.

[0058] S2000: Obtain the volume of the clothes after water absorption.

[0059] The volume of the clothes after water absorption is obtained, so as to perform step S3000. The volume of the clothes after water absorption is specifically the volume of the clothes after water absorption but before formal washing.

[0060] Specifically, step S2000 specifically includes step S2100 and step S2200.

[0061] S2100: Obtain the image of the clothes after water absorption.

[0062] The image of the clothes after water absorption is obtained, so as to determine the volume of the clothes after water absorption through the image.

[0063] Specifically, the laundry treating apparatus of the present application is provided with an image acquisition device, which is used to take pictures or videos towards the drum opening of the inner drum to obtain the image or video of the clothes in the inner drum; the image acquisition device is in communication connection with the controller and can transmit the taken image or video to the controller.

[0064] Exemplarily, the image acquisition device is a camera, which is installed on the shell or the drum door of the laundry treating apparatus and is arranged towards the drum opening of the inner drum.

[0065] S2200: Determine the volume of the clothes after water absorption according to the image.

[0066] After obtaining the image of the clothes after water absorption, the volume of the clothes after water absorption is determined according to the image.

[0067] It should be noted that in actual application, the contour of the clothes after water absorption can be determined through the image of the clothes after water absorption, to obtain a proportional relationship between the area occupied by the contour of the clothes and the area of the cylinder mouth of the inner cylinder, and then the proportional relationship is combined with the cross-sectional area of the inner cylinder to calculate the area of the contour of the clothes on the cross section, and then the horizontal depth of the inner cylinder is combined to calculate the volume of the clothes after water absorption; or, the vertical height of the clothes after water absorption in the inner cylinder can also be determined according to the image of the clothes after water absorption, and then the volume of the clothes after water absorption is determined according to the vertical height, and the like. These adjustments and changes related to the specific ways of determining the volume of the clothes after water absorption through the image of the clothes after water absorption do not deviate from the basic principles of the present application, and should be limited within the protection scope of the present application.

[0068] As a feasible implementation manner, the step S2200 specifically includes a step S2210 and a step S2220.

[0069] S2210: determining the vertical height of the clothes after water absorption according to the image.

[0070] After the image of the clothes after water absorption is obtained, the vertical height of the clothes after water absorption is determined according to the image.

[0071] Specifically, the image is first smoothed to make the brightness of the image gradually change, and the quality of the image is improved; then the contour of the clothes after water absorption is recognized according to the image, the average height plane of the clothes after water absorption is determined according to the top point position and the bottom point position of the top contour in the contour, and the intersection point of the average height plane and the first diameter of the inner cylinder is determined, denoted as H, wherein the first diameter is the diameter of the inner cylinder extending in the vertical direction, and the top point and the bottom point of the first diameter are denoted as A and B, respectively; then, the number of pixels occupied by the line segment AB in the image and the number of pixels occupied by the line segment BH in the image are determined; finally, the length of the line segment BH is calculated according to the length of the first diameter, the number of pixels occupied by the line segment AB, and the number of pixels occupied by the line segment BH.

[0072] In actual calculation process, the first ratio of the number of pixels occupied by the line segment BH to the number of pixels occupied by the line segment AB can be calculated first; the length of the line segment BH is obtained by multiplying the first ratio with the length of the first diameter; or, the second ratio of the length of the first diameter to the number of pixels occupied by the line segment AB can be calculated first; the length of the line segment BH is obtained by multiplying the second ratio with the number of pixels occupied by the line segment BH. The adjustments and changes of the specific calculation manner of the length of the line segment BH do not deviate from the basic principles of the present application, and should be limited within the protection scope of the present application.

[0073] The smoothing processing is specifically processing the pixel value of the pixel point with noise in the image into an approximate value of the value of the surrounding adjacent pixel points by mean filtering, box filtering, Gaussian filtering, median filtering or bilateral filtering, so as to improve the quality of the image. The top point and the bottom point of the top profile in the profile of the clothes are connected into a line segment, and an auxiliary surface, i.e. an average height plane, is made along the horizontal direction with the midpoint of the line segment as the reference point.

[0074] S2220: determining the volume of the clothes according to the vertical height of the clothes.

[0075] After the vertical height of the clothes after water absorption is determined, the volume of the clothes after water absorption can be determined according to the vertical height.

[0076] It should be noted that in actual application, before the clothes treatment device is shipped, the manufacturer can calculate the volume of the clothes corresponding to different vertical heights according to the diameter of the inner drum and the horizontal depth of the inner drum, and form a "vertical height and volume table" and store it in the controller of the clothes treatment device. When the vertical height is determined, the volume of the clothes to be washed can be directly queried in the "vertical height and volume table". Alternatively, a "comparison curve" can be made, in which the horizontal coordinate is the vertical height and the vertical coordinate is the volume, and the "comparison curve" is stored in the controller of the clothes treatment device. When the vertical height is determined, the corresponding volume can be directly determined from the "comparison curve". These specific determination methods for determining the volume of the clothes according to the vertical height of the clothes can be flexibly set by the person skilled in the art according to the actual situation, and the adjustment and change of the related steps do not deviate from the basic principles of the present application, and should be limited within the protection scope of the present application.

[0077] As another possible implementation, step S2200 includes step S2201 and step S2202.

[0078] S2201: determining the profile area of the clothes after water absorption according to the image.

[0079] Specifically, the image is first smoothed to create a gradual change in brightness, improving image quality. Then, the outlines of the water-absorbing clothing and the inner tube opening are identified from the image. Next, the number of pixels occupied by the inner tube opening and the water-absorbing clothing outline are determined. Finally, a third ratio is calculated between the number of pixels occupied by the water-absorbing clothing outline and the number of pixels occupied by the inner tube opening outline. This third ratio is multiplied by the area of ​​the inner tube opening to calculate the area of ​​the water-absorbing clothing outline. The smoothing process involves using methods such as mean filtering, box filtering, Gaussian filtering, median filtering, or bilateral filtering to approximate the pixel values ​​of noisy pixels to those of their neighboring pixels, thereby improving image quality.

[0080] In addition, after identifying the outline of the water-absorbing clothing, the coordinates of each point on the outline of the water-absorbing clothing can be obtained based on the pre-stored simulated image information and the coordinate values ​​of each region of the simulated image, thereby determining the outline area of ​​the water-absorbing clothing based on the coordinates of these points.

[0081] S2202: Determine the volume of the clothing after absorbing water based on the outline area.

[0082] Once the outline area of ​​the garment after absorbing water is determined, its volume can be determined based on that outline area.

[0083] Multiply the outline area of ​​the water-absorbed garment by the horizontal depth of the inner tub to obtain the volume of the water-absorbed garment.

[0084] S3000: Based on weight and volume, the garment handling equipment can selectively execute either a washing mode or an anti-collision detection mode, and selectively adjust the initial washing parameters of the washing mode based on the execution result of the anti-collision detection mode.

[0085] After obtaining the weight of the clothes and the volume of the clothes after absorbing water, the system determines whether the clothes are likely to be damaged based on the weight and volume. If there is no possibility of damage, the garment processing equipment directly executes the washing mode, washing the clothes according to the initial washing parameters of the washing mode. If there is a possibility of damage, the garment processing equipment executes the anti-collision detection mode, and selectively adjusts the initial washing parameters of the washing mode based on the execution result of the anti-collision detection mode, thereby reducing the probability of the clothes being damaged during the washing process.

[0086] Specifically, such as Figure 2 As shown, step S3000 includes steps S3100, S3200, S3300, S3400 and S3500.

[0087] S3100: judging whether the weight is less than the set weight.

[0088] The weight is compared with the set weight to judge whether the weight is less than the set weight, when the judgment result is "no", step S3200 is executed to make the laundry treatment device execute the washing mode; when the judgment result is "yes", step S3300 is executed to further judge whether the volume is greater than the set volume.

[0089] It should be noted that the value of the set weight in the present application is a fixed value, and the specific value is obtained by the manufacturer through testing different weights and different materials of clothes under different washing parameters before the laundry treatment device is shipped. For example, the testing method is as follows: all materials of clothes on the market (including carpets, blankets and down quilts, etc.) are selected, and multiple tests are carried out under different weights and different washing parameters, and the damage of the clothes after washing is observed, and according to the test results, the minimum weight of the clothes without damage is selected as the set weight, wherein the selection of the minimum weight does not consider the material of the clothes.

[0090] It should be further noted that although the set weight in the present application is a fixed value, because the running modes of different models of laundry treatment devices are different and the volumes of the inner cylinders are different, the values of the set weight obtained by test detection may also be different, therefore, the values of the set weight for laundry washing devices of different models and different inner cylinder volumes are not the same value.

[0091] In the present application, only when the weight of the clothes is less than the set weight, the clothes may be damaged; when the weight of the clothes is not less than the set weight, the clothes are tightly attached to the inner cylinder wall during the washing process, so as to be not easy to collide with the clothes blocking corner, and the probability of the clothes being damaged is low.

[0092] S3200: making the laundry treatment device execute the washing mode.

[0093] When the weight is not less than the set weight, it indicates that the weight of the clothes is above the set weight, so as to determine that the clothes will not be damaged basically during the washing process, and then the laundry treatment device executes the washing mode to directly wash the clothes according to the initial washing parameters corresponding to the washing mode.

[0094] S3300: judging whether the volume is greater than the set volume.

[0095] When the weight is less than the set weight, it indicates that the weight of the laundry is below the set weight, and thus it is determined that the laundry has a relatively high possibility of being damaged in the washing process, and thus it is necessary to further determine whether the volume is greater than the set volume by comparing the volume with the set volume. If the determination result is "No", step S3400 is executed to make the laundry treating apparatus perform the washing mode. If the determination result is "Yes", step S3500 is executed to make the laundry treating apparatus perform the anti-collision mode, and the initial washing parameter of the washing mode is selectively adjusted according to the execution result of the anti-collision mode.

[0096] It should be noted that the set volume in the present application is a fixed value, and the specific value thereof is obtained by a manufacturer through experiments on laundry of different volumes and different materials under different washing parameters before the laundry treating apparatus is shipped. For example, the experimental method is as follows: all materials of laundry on the market (including carpets, blankets, and down quilts, etc.) are selected, and multiple experiments are performed under different volumes (the volume here refers to the volume of the laundry after being absorbed) and different washing parameters, and the damage of the laundry after washing is observed. According to the experimental results, the maximum volume of the laundry without damage is selected as the set volume.

[0097] It should be further noted that although the set volume in the present application is a fixed value, the set volume obtained through experimental detection is not the same due to different running modes of different models of laundry treating apparatuses and different volumes of inner drums. Therefore, the set volume values of laundry washing apparatuses with different volumes of inner drums and different models of laundry treating apparatuses are not the same.

[0098] In the present application, only when the volume of the laundry after being absorbed is greater than the set volume, the laundry is likely to be damaged. When the volume of the laundry after being absorbed is not greater than the set volume, i.e., when the volume of the laundry is relatively small, the laundry is either close to the inner drum wall or not easy to be thrown in the washing process, and thus it is not easy to collide with the laundry blocking corner, and the probability of the laundry being damaged is relatively low.

[0099] Although the volume is directly compared with the set volume in the present embodiment, this should not constitute a limitation on the protection scope of the present application. In actual application, the ratio of the volume to the volume of the inner drum can be calculated first, and then the ratio is compared with the set ratio. According to the comparison result, the laundry treating apparatus is selectively made to perform the washing mode or the anti-collision detection mode, and the washing parameter of the washing mode is selectively adjusted according to the execution result of the anti-collision detection mode. Such adjustment and change related to the specific process of determining by volume do not deviate from the basic principles of the present application, and should be limited within the protection scope of the present application.

[0100] S3400: Enables the garment handling equipment to execute the washing mode.

[0101] When the volume is not greater than the set volume, it means that the volume of the clothes after absorbing water is below the set volume. This indicates that the clothes under this volume will not be damaged during the washing process. As a result, the clothes processing equipment will execute the washing mode and wash the clothes directly according to the initial washing parameters corresponding to the washing mode.

[0102] S3500: Enables the garment handling equipment to execute an anti-collision detection mode, and selectively adjusts the initial washing parameters of the washing mode based on the execution result of the anti-collision detection mode.

[0103] When the volume is greater than the set volume, it means that the volume of the clothes after absorbing water is above the set volume. Therefore, it is determined that the clothes under this volume are more likely to be damaged during the washing process. Thus, the clothes handling equipment needs to execute the anti-collision detection mode. Based on the execution result of the anti-collision detection mode, the initial washing parameters of the washing mode can be selectively adjusted to reduce the probability of the clothes being damaged during the washing process.

[0104] Specifically, such as Figure 2 As shown, step S3500 includes steps S3510 and S3520.

[0105] S3510: Enables the garment handling equipment to perform anti-collision detection mode to obtain collision parameters.

[0106] The garment handling equipment is made to perform an anti-collision detection mode to conduct an anti-collision detection experiment, and the analysis and evaluation are carried out to obtain collision parameters, so as to selectively adjust the initial washing parameters of the washing mode according to the collision parameters.

[0107] S3520: Selectively adjusts the initial washing parameters of the washing mode based on the collision parameters.

[0108] After determining the collision parameters, the initial washing parameters of the washing mode are selectively adjusted based on the collision parameters.

[0109] The collision parameters include, but are not limited to, the number of collisions and the ratio of collision areas.

[0110] Preferably, the collision parameters are the number of collisions and the collision area ratio. Specifically, the number of collisions is the total number of times the clothing collides with the corner of the clothing barrier during the anti-collision detection mode of the clothing processing device. The collision area ratio is specifically the ratio of the collision contact area to the area of ​​the corner of the clothing barrier when the clothing collides with the corner of the clothing barrier during the anti-collision detection mode of the clothing processing device. If multiple collisions occur, the collision area ratio is the average of the ratios of the multiple collisions.

[0111] In practical applications, the initial washing parameters of the washing mode can be adjusted selectively according to the numerical values of the collision parameters. For example, if the collision frequency is 0 and the collision area ratio is 0, i.e., no collision between the laundry and the laundry baffle occurs in the anti-collision detection experiment, it indicates that the probability of the laundry being damaged in the washing process is low, and the initial washing parameters of the washing mode are not adjusted, and the laundry treatment equipment performs the washing mode according to the initial washing parameters; if the collision frequency is not 0 and the collision area ratio is not 0, i.e., collision between the laundry and the laundry baffle occurs in the anti-collision detection experiment, it indicates that the laundry may be damaged due to collision in the washing process, and the initial washing parameters of the washing mode are adjusted.

[0112] Preferably, as shown in the figure, step S3510 includes step S3511, step S3512 and step S3513. Figure 3

[0113] S3511: rotating the inner drum at the initial washing rotational speed of the washing mode for a set time.

[0114] The inner drum rotates to drive the laundry to rotate. At the beginning of the rotation of the laundry, the position of the laundry changes and is prone to collide with the laundry baffle. Rotating the inner drum at the initial washing rotational speed of the washing mode for a set time simulates the washing stage, so as to determine the probability and severity of the collision between the laundry and the laundry baffle in the washing process according to the collision between the laundry and the laundry baffle in the simulation stage.

[0115] The washing mode can be a washing program selected by the user according to the number and material of the laundry through the control panel of the laundry treatment equipment, or a washing program automatically determined by the laundry treatment equipment according to the weight of the laundry. The initial washing rotational speed is the washing rotational speed corresponding to the washing program.

[0116] In practical applications, the user can input the specific numerical value of the set time through the control panel of the laundry treatment equipment; when the user does not set it, the set time is the time value preset by the laundry treatment equipment when it is manufactured. The present application does not limit the specific numerical value of the set time, as long as the set time can simulate the washing stage. For example, the set time is 30s. For example, the set time is 1min. Only in the stage of starting the rotation of the inner drum, the laundry is prone to collide with the laundry baffle when it is flung, therefore, the set time is preferably 30s-3min.

[0117] Preferably, step S3511 is repeated for three to five times. Repeating step S3511 multiple times can avoid errors in single detection, thereby improving the accuracy of the judgment.

[0118] S3512: obtaining a video of the inner drum during rotation. ​

[0119] A video of the inner drum during rotation is acquired so as to determine the collision parameter of the laundry according to the video.

[0120] Specifically, the laundry treating apparatus of the present application is provided with an image acquisition device for taking pictures or videos toward the drum opening of the inner drum so as to acquire images or videos of the laundry in the inner drum; the image acquisition device is in communication connection with the controller and can transmit the taken images or videos to the controller.

[0121] Exemplarily, the image acquisition device is a camera which is installed on the shell or the drum door of the laundry treating apparatus and is arranged toward the drum opening of the inner drum; the shooting angle of the camera can shoot the front of the laundry blocking angle, the drum opening of the inner drum and the inner wall of the inner drum.

[0122] S3513: determining the collision parameter of the laundry according to the video.

[0123] The collision parameter is the collision times and the collision area ratio.

[0124] After the video is acquired, the collision parameter of the laundry is determined according to the video.

[0125] Specifically, the step of "determining the collision parameter of the laundry according to the video" specifically comprises:

[0126] The video is processed to obtain the image of each frame.

[0127] The laundry contour and the laundry blocking angle contour in each frame of image are recognized, or the laundry contour and the laundry blocking angle contour in every several frames of image are recognized.

[0128] The laundry contour and the laundry blocking angle contour in the image are recognized so as to determine the collision parameter of the laundry according to the laundry contour and the laundry blocking angle contour. When the recognition is performed, each frame of image can be recognized, or every several frames of image can be recognized. Preferably, every several frames of image are recognized, which can improve the recognition speed, reduce the processing amount and further reduce the processing time, compared with recognizing each frame of image.

[0129] The collision parameter of the laundry is determined according to the laundry contour and the laundry blocking angle contour.

[0130] Find out all the clothes in the identified images colliding with the picture of the clothes corner, calculate the total number of pictures, that is, the number of collisions. Among them, the image of the clothes profile and the clothes corner profile has an overlapping position, which is the image of the collision phenomenon. Identify the overlapping area of the clothes profile and the clothes corner profile, get the area of the overlapping area, calculate the ratio of the overlapping area to the clothes corner profile area in each image. When there is only one image of the collision phenomenon, the ratio of the image is the collision area ratio. If there are multiple images of the collision phenomenon, add the multiple ratios and calculate the average ratio. The average ratio is the collision area ratio.

[0131] Preferably, as shown in Figure 4 Step S3520 includes step S3521, step S3522 and step S3523, step S3524 and step S3525.

[0132] S3521: According to the collision parameter, the risk level of the clothes is determined.

[0133] After determining the collision parameter, the risk level of the clothes is determined according to the collision parameter, so as to selectively adjust the initial washing parameter of the washing mode according to the risk level.

[0134] In practical application, according to the size of the collision parameter, the risk level is divided into multiple levels, and each risk level corresponds to a part of the range of the collision parameter, so as to better determine whether the initial washing parameter of the washing mode needs to be adjusted according to the risk level. Specifically, a group of risk levels is set at different speeds in different washing programs. Before the clothes processing equipment is put into the market, according to the damage degree of the clothes in the test results, different collision parameters are divided into different risk levels, thereby forming a "collision parameter and risk level table" and stored in the controller. When the collision parameter is determined, the corresponding "collision parameter and risk level table" is found according to the washing program and the initial washing speed, and then the corresponding risk level is directly determined by querying the "collision parameter and risk level table".

[0135] Exemplarily, the collision parameters include a collision frequency and a collision area ratio, each group of risk levels is divided into six levels from 0 to 5, wherein the risk level of 0 is defined as a risk-free level, and the risk levels of 1 to 5 are defined as risk levels; specifically, when the collision frequency of the collision parameters is 0 times and the collision area ratio is 0, it corresponds to 0 level; when the collision frequency of the collision parameters is in a first numerical range or the collision area ratio is in a first ratio range, it corresponds to 1 level; when the collision frequency of the collision parameters is in a second numerical range or the collision area ratio is in a second ratio range, it corresponds to 2 level; when the collision frequency of the collision parameters is in a third numerical range or the collision area ratio is in a third ratio range, it corresponds to 3 level; when the collision frequency of the collision parameters is in a fourth numerical range or the collision area ratio is in a fourth ratio range, it corresponds to 4 level; when the collision frequency of the collision parameters is in a fifth numerical range or the collision area ratio is in a fifth ratio range, it corresponds to 5 level; wherein the minimum value of the first numerical range is greater than 0, the minimum value of the second numerical range is greater than the maximum value of the first numerical range, the minimum value of the third numerical range is greater than the maximum value of the second numerical range, the minimum value of the fourth numerical range is greater than the maximum value of the third numerical range, and the minimum value of the fifth numerical range is greater than the maximum value of the fourth numerical range; the minimum value of the first ratio range is greater than 0, the minimum value of the second ratio range is greater than the maximum value of the first ratio range, the minimum value of the third ratio range is greater than the maximum value of the second ratio range, the minimum value of the fourth ratio range is greater than the maximum value of the third ratio range, and the minimum value of the fifth ratio range is greater than the maximum value of the fourth ratio range.

[0136] Specifically, the step of "selectively adjusting the initial washing parameter of the washing mode according to the risk level" specifically includes steps S3522, S3523, S3524 and S3525.

[0137] S3522: determining whether the risk level is 0 level.

[0138] The risk level is divided into multiple levels, wherein 0 level is defined as a risk-free level, i.e. there is no risk of damage to the clothes; and non-0 level is defined as a risk level, i.e. there is a risk of damage to the clothes; determining whether the risk level is 0 level, if the result is "yes", executing step S3523, not adjusting the initial washing parameter of the washing mode; if the result is "no", adjusting the initial washing parameter of the washing mode.

[0139] S3523: not adjusting the initial washing parameter of the washing mode.

[0140] When the risk level is 0 level, it means that there is no risk of damage to the clothes, so there is no need to adjust the initial washing parameter of the washing mode, and the clothes treatment equipment directly executes the washing mode according to the initial washing parameter.

[0141] Adjusting the initial washing parameter of the washing mode.

[0142] When the risk level is not level 0, it indicates that there is a risk of damage to the laundry, and the initial washing parameter of the washing mode needs to be adjusted.

[0143] Specifically, the step of "adjusting the initial washing parameter of the washing mode" specifically includes step S3524 and step S3525.

[0144] S3524: Obtain an adjustment parameter corresponding to the risk level.

[0145] The adjustment parameter is an adjusted washing parameter, or the adjustment parameter is an adjustment ratio of the washing parameter that needs to be adjusted.

[0146] Specifically, the washing parameters that can be adjusted include washing rotation speed, washing rotation stop ratio, and dehydration rotation speed.

[0147] The adjustment parameter corresponding to the risk level is obtained so as to adjust the initial washing parameter of the washing mode according to the adjustment parameter.

[0148] In actual application, before the laundry treatment device is shipped, the manufacturer can determine the adjustment parameter corresponding to different risk levels under different washing programs and different washing rotation speeds through a large number of tests. Specifically, the laundry with different risk levels under different washing programs and different washing rotation speeds is subjected to a washing test, the initial washing parameter corresponding to the washing program is adjusted during the experiment, and then the damage state of the laundry after washing is observed. In the case of not being damaged, the optimal washing parameter is selected as the adjustment parameter, or the optimal washing parameter is selected and compared with the initial washing parameter of the washing program to obtain an adjustment ratio, which is the washing parameter, thereby forming a "risk level and adjustment parameter comparison table" and storing it in the controller. When the risk level is determined, the corresponding "risk level and adjustment parameter comparison table" is found according to the washing program and the initial washing rotation speed, and then the corresponding adjustment parameter is directly obtained by querying the "risk level and adjustment parameter comparison table".

[0149] S3525: Adjust the initial washing parameter of the washing mode according to the adjustment parameter.

[0150] After obtaining the adjustment parameter corresponding to the risk level, the initial washing parameter of the washing mode is adjusted according to the adjustment parameter, and then the laundry treatment device is executed according to the adjusted washing parameter to perform the washing mode, so as to wash the laundry and effectively reduce the probability of damage to the laundry during washing.

Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical schemes after the changes or replacements will all fall within the protection scope of the present application.
