However, due to long-term structural aging, transportation damage, or improper user operation, the door can easily sag and deform, causing the door hook and lock to shift, exceeding the original design fit. This makes closing the door difficult or impossible, impacting normal user experience. Furthermore, due to the complex internal assembly structure of the door, repairs cannot be solved by simply replacing a single sub-component within the door; the entire door assembly must be replaced, resulting in high repair costs.

These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0063] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0064] The terms "first," "second," "third," "fourth," and so forth (if any) in the description and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein.

[0065] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0066] Currently, clothing handling devices typically feature a door on the front to facilitate loading and unloading clothing. Factors that contribute to door sagging include: decreased rigidity due to aging plastic structures, localized deformation caused by impact during transportation, and poor user habits. This can cause the door hook and latch to shift, exceeding the original design dimensions, making closing the door difficult or impossible, impacting user experience. Furthermore, due to the complex internal assembly structure of the door, repairs cannot be solved by simply replacing a single sub-component within the door; the entire door assembly must be replaced, resulting in high repair costs.

[0067] In order to solve the maintenance cost problem of replacing the entire door body due to sagging of the door body, the existing technology provides a movable door hook structure. The door hook is not fixed to the door body by screws, but adopts interference fit to clamp the door hook between two door body plastic frames, retaining a certain size space so that the door hook can be manually slid.

[0068] However, this structure cannot ensure that the door hook is always in the correct position. The door hook is repeatedly impacted by door closing at random positions, which deteriorates the working condition of the door hook-door lock and reduces its lifespan, affecting the user experience.

[0069] In response to the above problems, the present application provides a door hook self-positioning device. By building a door hook self-positioning device into the door body of the clothing processing device, the device includes a door hook, a motor, a main control module, a distance sensor, and a screw. The distance sensor measures the vertical distance from the door body to the ground in real time. The main control module is used to calculate the droop value of the door body and determine the target number of revolutions that the motor needs to rotate based on the door body droop value. The motor drives the screw to move the door hook to the target position. This device solves the problem that the door hook and door lock cannot cooperate properly due to door droop, thereby worsening the user experience. At the same time, the automatic adjustment of the door hook position can reduce the damage to the door hook and door lock caused by impact during the door closing process, thereby increasing the life of the door hook-door lock structure.

[0070] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be implemented independently or in combination with each other. For some embodiments, the same or similar concepts or processes may not be described in detail. The following embodiments of the present application are described in conjunction with the accompanying drawings.

[0071] Figure 1 This is a schematic diagram of the structure of the door hook self-positioning device provided in this application. It should be noted that, Figure 1 The schematic diagram of each component of the door hook self-positioning device is shown. The specific structure of the remaining components of the door hook self-positioning device is not limited to Figure 1 of examples.

[0072] See Figure 1 The door hook self-positioning device provided in this application may include a door hook 1, a motor 2, a main control module 3, a distance sensor 4 and a screw 5.

[0073] The distance sensor 4 is disposed at the bottom of the inner frame 61 of the door body of the clothes processing device. The distance sensor 4 is used to measure a target vertical distance value between the door body 6 and the ground.

[0074] The main control module 3 is connected to the distance sensor 4 and the motor 2 respectively. The main control module is used to process the data measured by the distance sensor 4 and control the motor 2 to rotate according to the target number of revolutions. There is a correlation between the target number of revolutions and the target vertical distance value.

[0075] The door hook 1 is connected to the motor 2 through a screw 5, and the door hook 1 is located above the motor 2, so that the door hook 1 moves horizontally in the vertical direction to the target position based on the power generated by the motor 2 rotating a target number of times transmitted by the screw 5.

[0076] Exemplarily, the distance sensor 4 can be an infrared ranging sensor, which can be fixed to the door body frame 61 of the clothing processing device by limiting ribs and screws. The ranging probe of the distance sensor 4 can extend to the outside of the door body through the hole set on the door body frame 61, thereby measuring the vertical distance between the door body and the ground without affecting the appearance of the clothing processing device and without interfering with the front panel.

[0077] Specifically, the motor 2 is fixed to the door inner frame 61 by screws, and the motor 2 is located below the door hook 1, which not only ensures the stability of its own structure but also supports the door hook 1.

[0078] The door hook self-positioning device provided in the embodiment of the present application deploys a door hook, a motor, a main control module, a distance sensor and a screw on the door body frame of the clothing processing device, and the distance sensor is set at the bottom of the door body frame of the clothing processing device. The distance sensor is used to measure the target vertical distance value between the door body and the ground. The main control module is connected to the distance sensor and the motor respectively. The main control module is used to process the data measured by the distance sensor and control the motor to rotate according to the target number of circles. There is a correlation between the target number of circles and the target vertical distance value. The door hook is connected to the motor through a screw, and the door hook is located above the motor, so that the door hook can move horizontally in the vertical direction to the target position based on the power generated by the motor rotating the target number of circles transmitted by the screw; the device avoids the problem of deterioration of the door hook working condition due to sagging of the door body by automatically adjusting the position of the door hook, thereby improving the service life of the door hook and user experience.

[0079] When the door hook needs to perform vertical translational movement in a stable structural state without exceeding a limit range so as to cooperate with the door lock, a limit setting is required for the door hook. Therefore, in some examples, the door hook self-positioning device further includes a limit device 7.

[0080] Figure 2 Schematic diagram of the structure of the limiting device provided in the embodiment of the present application Figure 1 , Figure 3 Schematic diagram of the structure of the limiting device provided in the embodiment of the present application Figure 2 , Figure 3 for Figure 2 Cross-sectional view of the limit device in . Figure 2 and Figure 3 The limiting device 7 includes: a plurality of limiting ribs located in different directions, and the door hook 1 abuts against the first limiting rib 71 and the second limiting rib 72 along the front and rear directions respectively to limit the movement of the door hook 1 between the door inner frame 61 and the door middle frame 62 of the clothing processing device.

[0081] The door hook 1 abuts against the third limiting rib 73 and the fourth limiting rib 74 along the horizontal direction, so as to limit the movement of the door hook 1 in the door inner frame 61 along the horizontal direction.

[0082] A fifth limiting rib 75 is provided on the door body inner frame 61 along the vertical direction of the door hook 1 to limit the door hook 1 from moving upward in the vertical direction and not exceeding the position of the fifth limiting rib 75 .

[0083] Specifically, the first limiting rib 71 can be a limiting rib set in the front position of the door body inner frame 61, and the second limiting rib 72 can be a limiting rib set on the door body middle frame 62. The first limiting rib 71 and the second limiting rib 72 are set in relative directions to limit the movement of the door hook 1 in the front and rear directions. There is no special restriction on the number of the first limiting rib 71 and the second limiting rib 72.

[0084] It can be understood that the third limiting rib 73 can be the limiting rib on the left side of the door inner frame 61 in the horizontal direction, and the fourth limiting rib 74 can be the limiting rib on the right side of the door inner frame 61 in the horizontal direction. The third limiting rib 73 and the fourth limiting rib 74 limit the left and right movement of the door hook in the horizontal direction. There is no special restriction on the number of the third limiting rib 73 and the fourth limiting rib 74 here.

[0085] Here, the fifth limiting rib 75 may be a limiting rib provided on the door inner frame 61, extending a certain distance beyond the top of the door hook 1, to limit the vertical upward translation of the door hook 1 under the force of the motor 2, so as not to exceed a predetermined range. The bottom of the door hook 1 is supported by the motor 2, so a limiting rib is not provided.

[0086] The door hook self-positioning device provided in the embodiment of the present application deploys the door hook in the door body frame of the clothing processing device through a limiting rib device, so that the door hook is restricted by multiple limiting ribs in the horizontal direction, front and back direction, and above. While ensuring the stability and reliability of the door hook structure, the door hook can move horizontally within the restricted range, so that the door hook can move horizontally in the vertical direction to the target position based on the power of the motor transmitted by the screw, thereby realizing automatic adjustment of the door hook.

[0087] Furthermore, in a specific example, the main control module 3 includes: a base 31 , a top cover 32 (not shown in the figure), and a control module 33 .

[0088] Figure 4 This is a schematic diagram of the structure of the main control module provided in the embodiment of the present application. Figure 4 As shown, the base 31 and the top cover 32 are fixed to the inner frame 61 of the door of the clothing processing device by screws. A groove 311 is provided inside the base 31 for accommodating the control module.

[0089] See Figure 4 and Figure 1 The control module 33 is connected to the motor 2 and the distance sensor 4 respectively. The control module 33 is used to process the data measured by the distance sensor 4 to obtain a target number of revolutions and control the motor 2 to rotate according to the target number of revolutions.

[0090] Specifically, the base 31 may further include a plurality of wiring grooves for connecting the plurality of modules in the grooves 311 in the base 31 and cooperating with the top cover 32 to achieve internal fixation of the main control module 3. The number of grooves 311 provided in the base 31 may be one or more, and this application does not impose any particular limitation on the number of grooves.

[0091] Optionally, the connection between the main control module 3 and the door body frame 61 can adopt a limiting rib structure, such as Figure 4As shown, the main control module 3 abuts against the sixth limiting rib 76 to achieve pre-positioning of the main control module 3 in the door body inner frame 61, reducing installation difficulty and improving assembly efficiency.

[0092] In a possible implementation, the main control module 3 further includes a battery 34 , which is connected to the control module 33 . The battery 34 is used to supply power to the control module 33 .

[0093] The door hook self-positioning device provided in the embodiment of the present application is configured by providing a top cover, a base and a control module for the main control module, and fixing the base and the top cover to the door body frame of the clothing processing device by screws. A groove is provided inside the base for accommodating the control module, and the control module is respectively connected to the motor and the distance sensor, so that the control module can process the data measured by the distance sensor to obtain the target number of circles, and control the motor to rotate according to the target number of circles, so that the door hook can move horizontally in the vertical direction to the target position based on the power of the motor transmitted by the screw, thereby realizing automatic adjustment of the door hook.

[0094] Figure 5 This is the process of the control method of the door hook self-positioning device provided in the embodiment of the present application Figure 1 , applied to a door hook self-positioning device, the door hook self-positioning device is deployed in the door body frame of the clothing processing equipment, the door hook self-positioning device includes: a door hook, a motor, a main control module, a distance sensor and a screw, such as Figure 5 As shown, the method includes:

[0095] S101. Obtaining, through a main control module, a target vertical distance value between a door of a clothing processing device and the ground measured by a distance sensor.

[0096] The target vertical distance value refers to the vertical distance value between the door body and the ground obtained by the main control module in real time based on the distance sensor measurement.

[0097] It can be understood that the distance sensor can detect the vertical distance between the door body of the clothing processing equipment and the ground through the sensor probe, and convert the detected signal into a digital signal after processing and transmit it to the main control module connected to it. The main control module can calculate the target vertical distance value between the door body and the ground based on the received information.

[0098] S102: Control the motor to rotate according to the target number of revolutions based on the target vertical distance value.

[0099] There is a correlation between the target number of revolutions and the target vertical distance value. The target number of revolutions refers to the number of revolutions required for the motor to generate the power required to push the door hook to the target position.

[0100] For example, the main control module can compare the target vertical distance value with the standard vertical distance value to obtain the difference between the vertical distance value between the current door body and the ground and the vertical distance value between the door body and the ground under the standard state. Based on the size of the difference, the main control module determines the target adjustment displacement of the door hook. Then, based on the target adjustment displacement required for the door hook to move horizontally, the main control module determines the target number of revolutions required for the motor to rotate, and controls the motor to rotate according to the target number of revolutions. This is done so that the door hook can move vertically to the target position based on the power generated by the target number of revolutions of the motor transmitted by the screw. The target position refers to the position to which the door hook moves upward according to the target adjustment displacement, so as to ensure that the door hook can cooperate with the door lock at the target position.

[0101] It is understandable that when the door body of the clothing processing equipment has problems such as sagging and deformation, the position of the door hook on the inner frame of the door body will also be offset, causing the door hook to be unable to work normally with the door lock. Therefore, this step controls the motor to rotate according to the target vertical distance value through the main control module according to the target number of turns, and the screw converts the rotational motion of the motor into a translational motion in the vertical direction of the door hook, thereby automatically adjusting the position of the door hook to avoid the clothing processing equipment from being unable to be used normally due to sagging of the door body.

[0102] The control method of the door hook self-positioning device provided in an embodiment of the present application obtains the target vertical distance value between the door body of the clothing processing equipment and the ground measured by the distance sensor through the main control module, and controls the motor to rotate according to the target vertical distance value, so that the door hook moves horizontally in the vertical direction to the target position based on the power generated by the motor rotating the target number of times transmitted by the screw, and there is a correlation between the target number of turns and the target vertical distance value; the method avoids the problem of deterioration of the door hook working condition due to sagging of the door body by automatically adjusting the position of the door hook, thereby improving the service life of the door hook and user experience.

[0103] Figure 6 This is the process of the control method of the door hook self-positioning device provided in the embodiment of the present application Figure 2 This embodiment is based on Figure 5 Based on the embodiment, the control method of the door hook self-positioning device is described in detail. Figure 6 As shown, the control method of the door hook self-positioning device provided in this embodiment includes:

[0104] S201. Obtain, through a main control module, a target vertical distance value between a door of a clothing processing device and the ground measured by a distance sensor.

[0105] Step S201 is similar to the above-mentioned step S101 and will not be described again here.

[0106] S202: Determine a first droop value of the door body according to the target vertical distance value and the first vertical distance value.

[0107] Among them, the first vertical distance value is the vertical distance value between the door body and the ground initially measured by the distance sensor, the first droop value refers to the difference between the target vertical distance value and the first vertical distance value, and the first droop value is used to reflect the droop degree of the door body.

[0108] It can be understood that, considering the actual application scenarios of the clothing processing equipment, the bottom angle heights of the clothing processing equipment when installed by the user are different. Therefore, the first vertical distance value can be the vertical distance value between the door body and the ground measured by the distance sensor when the clothing processing equipment is first started after installation, and the target vertical distance value can be the vertical distance value between the door body and the ground obtained by the distance sensor detecting according to a preset interval time after the user has used the clothing processing equipment for a period of time.

[0109] In this step, since the door body of the clothing processing equipment will sag and deform to varying degrees with long-term use, a first drooping value that can reflect the drooping amount of the door body can be obtained based on the difference between the first vertical distance value and the target vertical distance value.

[0110] S203, determining whether the first droop value is greater than a first preset value; if so, executing step S204; if not, executing step S206.

[0111] The first preset value may be a door body sagging threshold value set based on experience. The first preset value is used to reflect the difference between the target vertical distance value and the first vertical distance value. The specific sagging threshold value is not specifically limited. Optionally, the first preset value may be obtained based on a preset empirical value and a preset deviation value. For example, the first preset value may be 0.1 mm, 0.2 mm, or 0.3 mm.

[0112] It can be understood that when the first droop value is greater than the first preset value, the difference between the vertical distance value from the door body to the ground and the first vertical distance value is slightly larger, and the droop amount has exceeded the preset droop amount threshold, that is, the offset of the relative position between the door hook and the door lock is large, which may cause the door hook and the door lock to fail to cooperate normally, thereby worsening the working condition of the door hook-door lock, and making it impossible for the user to close the door of the clothing processing equipment normally. Therefore, it is necessary to adjust the position of the door hook through the door hook self-positioning device.

[0113] When the first droop value is not greater than the first preset value, the vertical distance value from the door body to the ground is approximately the same as the first vertical distance value, and the droop amount does not exceed the preset droop amount threshold, that is, the door hook is still in a position where it can work normally with the door lock, and there is no need to adjust its position.

[0114] S204: Determine a target adjustment displacement of the door hook according to the first droop value, the first parameter, and the second parameter, and determine a target number of rotations of the motor according to the target adjustment displacement and the pitch of the screw.

[0115] Among them, the first parameter refers to the horizontal distance from the center of the door hook to the door axis, and the second parameter refers to the vertical distance from the center of the distance sensor probe to the bottom corner of the clothing processing device. The first parameter and the second parameter are both design parameters of the clothing processing device equipped with a door hook self-positioning device.

[0116] Figure 7 This is a schematic diagram of the target adjustment displacement of the door hook provided in the embodiment of the present application. Figure 7 As shown, the horizontal distance from the center of the door hook to the door axis is the first parameter d1, the vertical distance from the center of the distance sensor probe to the bottom corner of the clothing processing device is the second parameter d2, the first vertical distance value between the door body and the ground obtained by the initial measurement is L1, and the target vertical distance value between the door body and the ground obtained by the second measurement is L2.

[0117] The first droop value of the door body can be calculated using the following formula, for example: ΔL=L1-L2

[0118] It can be understood that when the door body of the clothing processing equipment sags and deforms, the door hook deployed on the inner frame of the door will also sag to a certain extent, and since the distance sensor and the door hook in the door hook self-positioning device are fixed on the inner frame of the door body, there is a similar triangle relationship between the first drooping value ΔL of the door body detected by the distance sensor through the probe and the second parameter and the drooping value ΔA of the door hook.

[0119] The door hook sag value can be calculated using the following formula: ΔA=ΔL×d1 / d2

[0120] Among them, ΔA is the droop value corresponding to the door hook, ΔL is the first droop value of the door body, d1 is the first parameter, and d2 is the second parameter.

[0121] In this step, the droop value ΔA of the door hook is also the target adjustment displacement corresponding to the door hook. Since the door hook converts the rotational motion of the motor into vertical upward translational motion through a screw, the target number of revolutions that the motor needs to rotate can be determined based on the target adjustment displacement of the door hook and the pitch of the screw. For example, if the pitch of the screw is 0.7mm, the door hook will be displaced by 0.7mm when the motor rotates one circle.

[0122] The target number of laps can be calculated using the following formula, for example: r=ΔA / S

[0123] Where r is the target number of revolutions the motor needs to rotate, ΔA is the target adjustment displacement, and S is the screw pitch.

[0124] S205: Control the motor to rotate according to the target number of revolutions.

[0125] Among them, the main control module can control the motor to rotate according to the target number of turns, so that the door hook can move horizontally in the vertical direction to the target position based on the power generated by the motor rotating the target number of turns transmitted by the screw.

[0126] Optionally, after the motor rotates the target number of revolutions to make the door hook move horizontally to the target position and completes one adjustment, the adjustment effect of the door hook can also be verified based on the degree of sagging of the door body before the door hook is adjusted.

[0127] Exemplarily, determine whether the first droop value is greater than the second preset value; when the first droop value is greater than the second preset value, restart the distance sensor to obtain a second vertical distance value; obtain a second droop value based on the second vertical distance value and the first vertical distance value; determine the adjustment state of the door hook based on the second droop value and the first preset value.

[0128] Among them, the second preset value is greater than the first preset value, and the second preset value is used to indicate the specific value of the door body droop value that needs to be verified for the door hook adjustment effect. When the first droop value is greater than the second preset value, the difference between the vertical distance value from the door body to the ground and the first vertical distance value is large. At this time, the adjustment effect of the adjusted door hook needs to be verified.

[0129] By re-detecting the vertical distance from the door body to the ground, the second vertical distance value from the door body to the ground after the door hook is adjusted can be obtained. According to the difference between the second vertical distance value and the first vertical distance value, the second droop value is obtained. By judging whether the second droop value exceeds the first preset value, the adjustment status of the door hook can be determined. For example, if the second droop value does not exceed the first preset value, it indicates that the last adjustment of the door hook was good, the door hook is in a good adjustment state, and can work normally with the door lock; if the second droop value exceeds the first preset value, it indicates that the last adjustment of the door hook was poor, the door hook is in an abnormal adjustment state, that is, the door hook is still not in the correct position, and the door hook needs to be adjusted again.

[0130] S206: After a preset time interval, restart the distance sensor so that the distance sensor measures the vertical distance between the door of the clothes processing device and the ground again.

[0131] The preset duration may be, for example, 1 day or 2 days. The specific value is determined according to the actual situation. The preset duration is used to indicate the specific time point for re-ranging.

[0132] It can be understood that when the first drooping value of the door body is not greater than the first preset value, it means that the drooping amount of the door body is still within the original design size range, and the door hook and the door lock are still maintained in a normal working condition. There is no need to adjust the door hook. After a preset time interval, the distance sensor can be restarted to measure the distance and obtain the vertical distance value from the door body to the ground to re-judge whether the door hook needs to be adjusted.

[0133] The control method of the door hook self-positioning device provided in the embodiment of the present application obtains the target vertical distance value between the door body of the clothing processing equipment and the ground measured by the distance sensor through the main control module, and determines the first droop value of the door body according to the target vertical distance value and the first vertical distance value, and the first vertical distance value is the vertical distance value between the door body and the ground initially measured by the distance sensor; judges whether the first droop value is greater than the first preset value; if the first droop value is greater than the first preset value, determines the target adjustment displacement of the door hook according to the first droop value, the first parameter and the second parameter, and determines the electric the target number of revolutions of the machine; if the droop value is not greater than the first preset value, the distance sensor is restarted after a preset time interval so that the distance sensor measures the vertical distance value between the door body of the clothing processing device and the ground again; the motor is controlled to rotate according to the target number of revolutions, so that the door hook moves horizontally in the vertical direction to the target position based on the power generated by the target number of revolutions of the motor transmitted by the screw; the method improves the adjustment effect of the door hook by automatically adjusting the position of the door hook and verifying the adjustment effect of the door hook, avoids the problem of deterioration of the door hook working condition due to drooping of the door body, thereby improving the service life of the door hook and user experience.
