In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0052] This embodiment provides a wire rope damage detection device 20 and a clothes drying machine. Figure 1 As shown, the clothes drying machine includes a housing 10, a driving mechanism 30, and a drying mechanism 40. The housing 10 is used to be fixed on the ceiling, and the housing 10 forms a storage space. The driving mechanism 30 and the electrical components of the clothes drying machine are arranged in the storage space of the housing 10. The driving mechanism 30 includes a lifting driving source 32 and a steel wire rope 31. The lifting driving source 32 is arranged in the housing 10. One end of the steel wire rope 31 is connected to the output end of the lifting driving source 32, and the other end is connected to the drying mechanism 40. The lifting driving source 32 can drive the steel wire rope 31 to reel up, so as to drive the drying mechanism 40 to move up and down. In this embodiment, the clothes drying machine includes two steel wire ropes 31, one end of the two steel wire ropes 31 is connected to the output end of the lifting driving source 32, and the other end of the two steel wire ropes 31 is respectively connected to the two ends of the drying mechanism 40 along the length direction, so as to ensure that the lifting process of the drying mechanism 40 is stable. It can be understood that, without violating the inventive concept of the present application, the lifting driving source 32 can be any existing structure that can drive the steel wire rope 31 to reel up.

[0053] Preferably, if Figure 1 As shown, the clothes drying machine also includes a scissor frame mechanism 50, the upper end of which is connected to the housing 10, and the lower end is connected to the drying mechanism 40. When the lifting drive source 32 drives the steel wire rope 31 to be retracted and the drying mechanism 40 rises, the scissor frame mechanism 50 is adaptively folded and retracted; when the lifting drive source 32 drives the steel wire rope 31 to be unfolded and the drying mechanism 40 to be lowered, the scissor frame mechanism 50 is adaptively unfolded, thereby guiding the lifting process of the drying mechanism 40 and ensuring the stability of the lifting process. The scissor frame mechanism 50 is a commonly used guiding structure in the clothes drying machine, and its specific working principle is not limited here. In some embodiments, the lower side surface of the housing 10 is provided with an opening, and the lifting drive source 32 can drive the drying mechanism 40 to move upward and be stored inside the housing 10, thereby improving the aesthetics of the clothes drying machine. In some embodiments, the drying mechanism 40 includes a clothes drying rod. In some embodiments, the drying mechanism 40 includes both a clothes drying rod and a quilt drying rod.

[0054] Generally, the steel wire rope 31 is made of multiple strands of steel wires, which may become worn and thinner during long-term use, or may become burred due to the breakage of some steel wires, thereby causing the steel wire rope 31 to partially thicken. The thinning and thickening of the steel wire rope 31 will both bring safety hazards to the clothes drying machine. In view of this problem, in the prior art, professionals are usually required to manually inspect the steel wire rope 31 after the clothes drying machine has been used for a period of time, which increases the after-sales cost of the clothes drying machine and poor user experience.

[0055] In this regard, in this embodiment, if Figure 1 and Figure 2 As shown, the clothes drying machine further includes a wire rope damage detection device 20, which includes a first clamping assembly 21, a second clamping assembly 22, an elastic member 23, a distance detection assembly 24 and a control assembly. The first clamping assembly 21 is mounted on the housing 10 of the clothes drying machine and is located in the accommodation space of the housing 10. The elastic member 23 is connected between the housing 10 and the second clamping assembly 22, and enables the second clamping assembly 22 to have a predetermined direction ( Figure 2 The wire rope 31 is elastically clamped between the first clamping assembly 21 and the second clamping assembly 22 to show a tendency of the wire rope 31 to approach the first clamping assembly 21 (in the X direction). The distance detection assembly 24 can detect the size of the wire rope 31 clamped between the first clamping assembly 21 and the second clamping assembly 22 in a preset direction. The control assembly is communicatively connected to the distance detection assembly 24, and the control assembly can respond according to the detection result of the distance detection assembly 24. It should be noted that, in the process of the lifting drive source 32 driving the wire rope 31 to lift, different parts of the wire rope 31 pass through the first clamping assembly 21 and the second clamping assembly 22 in turn, so that the distance detection assembly 24 detects the size of each part of the wire rope 31 in turn.

[0056] The wire rope damage detection device 20 in this embodiment is provided with a first clamping component 21 connected to the housing 10 and a second clamping component 22 connected to the housing 10 through an elastic member 23, so that the distance between the first clamping component 21 and the second clamping component 22 can be adaptively changed as the thickness of the wire rope 31 changes, so that the distance detection component 24 can directly and accurately detect the size of the wire rope 31 in a preset direction, that is, to achieve real-time monitoring of safety such as whether the wire rope 31 is worn or has burrs, and the control component makes other components of the clothes drying machine make corresponding responses (described in detail below) according to the size detection result of the wire rope 31, thereby reminding or restricting the user, that is, there is no need for manual regular inspection of the wire rope 31 of the clothes drying machine, and the user experience is good.

[0057] Optionally, in this embodiment, the first clamping assembly 21 and the second clamping assembly 22 are arranged in the vertical direction, and the preset direction is the vertical direction. In other embodiments, the first clamping assembly 21 and the second clamping assembly 22 can also be arranged in the horizontal direction or tilted, in which case the preset direction is consistent with the arrangement direction of the first clamping assembly 21 and the second clamping assembly 22.

[0058] Preferably, the control component is communicatively connected with the lifting drive source 32, and one of the responses made by the control component according to the size detection result of the distance detection component 24 is: controlling the lifting drive source 32 to stop output, that is, the drying mechanism 40 of the clothes drying machine cannot be raised or lowered and cannot be used, thereby limiting the user's use and eliminating safety hazards.

[0059] Specifically, when the distance detection component 24 detects that the size of the steel wire rope 31 in the preset direction is less than or equal to the first preset size, or greater than or equal to the third preset size, the lifting drive source 32 stops outputting. The first preset size is less than or equal to the standard diameter of the steel wire rope 31, and the third preset size is greater than the standard diameter of the steel wire rope 31. When the size of the steel wire rope 31 in the preset direction is less than or equal to the first preset size, it indicates that the steel wire rope 31 is severely worn locally and has reached the safety limit; when the size of the steel wire rope 31 in the preset direction is greater than or equal to the third preset size, it indicates that the steel wire of the steel wire rope 31 is more broken, has more burrs, and has reached the safety limit of the steel wire rope 31. At this time, the lifting drive source 32 stops outputting to ensure the safety of the user.

[0060] In some cases, impurities on the surface of the wire rope 31 may also cause its size detection result to be greater than the standard diameter. If it is directly determined that too many steel wires of the wire rope 31 are broken and the clothes drying machine stops working, an erroneous judgment will occur and affect the user's normal use.

[0061] In this regard, in this embodiment, if Figure 1 As shown, the wire rope damage detection device 20 also includes a cleaning component 26, which can clean the wire rope 31. The cleaning component 26 is connected to the control component in communication, and the control component can start the cleaning component 26 when the size of the wire rope 31 in the preset direction detected by the distance detection component 24 is greater than or equal to the second preset size. Starting the cleaning component 26 is another response made by the control component according to the size detection result of the distance detection component 24. In this embodiment, the second preset size is greater than the standard diameter of the wire rope 31 and less than the third preset size.

[0062] Specifically, when the distance detection component 24 detects that the size of the steel wire rope 31 is greater than the second preset size, the possible reason is that the wire of the steel wire rope 31 is broken and produces more burrs, or it may be that the steel wire rope 31 is covered with impurities. At this time, the control component controls the cleaning component 26 to clean the steel wire rope 31 based on the detection structure of the distance detection component 24. If the steel wire rope 31 is covered with impurities, the cleaning component 26 can remove the impurities. Next, the distance detection component 24 detects the size of the steel wire rope 31 again. If the size of the steel wire rope 31 is greater than the second preset size, the situation that the steel wire rope 31 is covered with foreign matter can be ruled out, and it is confirmed that the steel wire rope 31 is at risk due to the breakage of the steel wire. At this time, the clothes drying machine is stopped. Through the above-mentioned settings, it is possible to avoid the situation where the safety status of the steel wire rope 31 is misjudged due to the impurities covering the steel wire rope 31.

[0063] It should be noted that when the distance detection component 24 detects that the local size of the wire rope 31 is larger than the second preset size, and after the cleaning component 26 cleans the wire rope 31, the control component can control the lifting drive source 32 to drive the wire rope 31 to move in the opposite direction, so that the local position of the wire rope 31 passes again between the first clamping component 21 and the second clamping component 22, and then the distance detection component 24 re-detects the local position of the wire rope 31. The control component determines whether to stop the output of the lifting drive source 32 based on the re-detection result of the local area.

[0064] In some embodiments (not shown), the cleaning component 26 includes a rotating drive source and a cam, and the rotating drive source is mounted on the housing 10 and is communicatively connected to the control component. The cam is connected to the output end of the rotating drive source, and the rotating drive source can drive the cam to rotate so that the cam intermittently contacts and shakes the wire rope 31. When the distance detection component 24 detects that the size of the wire rope 31 along the preset direction is greater than or equal to the second preset size, a working signal is sent to the rotating drive source, and the rotating drive source drives the cam to rotate. During the rotation of the cam, the cam intermittently contacts the wire rope 31, causing the wire rope 31 to shake, thereby removing impurities on the wire rope 31. Optionally, the rotating drive source can be specifically a motor.

[0065] In some embodiments, the cleaning component 26 includes an ultrasonic cleaning mechanism, and the wire rope 31 passes through the ultrasonic cleaning mechanism. When the distance detection component 24 detects that the size of the wire rope 31 along a preset direction is greater than or equal to a second preset size, a working signal is sent to the ultrasonic cleaning mechanism, and the ultrasonic cleaning mechanism cleans the wire rope 31.

[0066] Taking the standard diameter of the wire rope 31 as 4mm as an example, the first preset size can be 3.5mm, the second preset size can be 4.5mm, and the third preset size can be 5mm. When the distance detection component 24 detects that the size of the wire rope 31 in the preset direction is less than or equal to 3.5mm, the control component determines that the wire rope 31 is seriously worn and thinned, and there is a safety hazard, and stops the output of the lifting drive source 32; when the distance detection component 24 detects that the size of the wire rope 31 in the preset direction is greater than or equal to 4.5mm, the control component determines that the wire rope 31 is partially covered with impurities or there is a safety hazard due to the breakage of the steel wire, and causes the cleaning component 26 to clean the wire rope 31; after the cleaning component 26 finishes cleaning, the control component causes the lifting drive source 32 to drive the wire rope 31 to move in the opposite direction, and causes the distance detection component 24 to re-detect the size of the local part of the wire rope 31. If the size of the local part is greater than or equal to 4.5mm, the control component determines that there is a safety hazard in the wire rope 31, and stops the output of the lifting drive source 32.

[0067] like Figure 2 As shown, the distance detection component 24 includes a first trigger 241 and a first distance detection component 242, wherein the first trigger 241 is connected to the second clamping component 22, the first distance detection component 242 is connected to the first clamping component 21, and the first distance detection component 242 is connected to the control component in communication, and the first distance detection component 242 can trigger the control component to respond after contacting the first trigger 241. Specifically, when the wire rope 31 is worn and thinned, the second clamping component 22 is close to the first clamping component 21 under the action of the elastic member 23, so the first distance detection component 242 is close to the first trigger 241. When the first distance detection component 242 contacts the first trigger 241, it indicates that the current size of the wire rope 31 in the preset direction reaches the first preset size. At this time, the first distance detection component 242 sends a signal to the control component, and the control component stops the output of the lifting drive source 32 based on the signal. It can be understood that, without violating the inventive concept of the present application, the first distance detection component 242 can be any existing component that can realize distance detection.

[0068] like Figure 2As shown, the distance detection component 24 also includes a second trigger 243 and a second distance detection component 244, wherein the second trigger 243 is connected to the second clamping component 22, the second distance detection component 244 is connected to the housing 10, the second distance detection component 244 can detect the distance between it and the second trigger 243 along a preset direction, and the second distance detection component 244 is connected to the control component. Specifically, when the steel wire rope 31 becomes larger in size due to impurities being adhered to it or burrs being generated due to steel wire breakage, the second clamping component 22 will move in a direction away from the first clamping component 21, that is, in a direction toward the housing 10, thereby driving the second trigger 243 to approach the second distance detection component 244. When the distance between the second trigger 243 and the second distance detection member 244 is less than or equal to the first value, it means that the size of the wire rope 31 along the preset direction is greater than or equal to the second preset size. At this time, the second distance detection member 244 sends a corresponding signal to the control component, and the control component controls the cleaning component 26 to work; when the distance between the second trigger 243 and the second distance detection member 244 is less than or equal to the second value, it means that the size of the wire rope 31 along the preset direction is greater than or equal to the third preset size. At this time, the second distance detection member 244 sends a corresponding signal to the control component, and the control component controls the lifting drive source 32 to stop working. It can be understood that, without violating the inventive concept of the present application, the second distance detection member 244 can be any existing component that can realize distance detection.

[0069] In this embodiment, the thinning condition of the wire rope 31 is detected and judged by the first distance detection component 242, and the thickening condition of the wire rope 31 is detected and judged by the second distance detection component 244, that is, the thickening and thinning states of the wire rope 31 are respectively identified, the detection result is accurate and highly sensitive, and the calculation procedure of the control component is also simpler.

[0070] like Figure 2 As shown, the first clamping assembly 21 includes a first bracket 211 and a first pulley 212, the first bracket 211 is connected to the housing 10, the first pulley 212 is rotatably supported on the first bracket 211, the second clamping assembly 22 includes a second bracket 221 and a second pulley 222, the second bracket 221 is connected to the housing 10 through an elastic member 23, the second pulley 222 is rotatably supported on the second bracket 221, and the wire rope 31 passes between the first pulley 212 and the second pulley 222. In the process of winding the wire rope 31, there is rolling friction between the first pulley 212 and the second pulley 222 and the wire rope 31, so that the wear of the wire rope damage detection device itself on the wire rope 31 can be reduced as much as possible.

[0071] In this embodiment, the first clamping assembly 21 further includes a mounting frame 213, the mounting frame 213 is fixed on the housing 10, the first bracket 211 is fixed on the mounting frame 213, and the first pulley 212 is supported on the first bracket 211 through a rotating shaft. The first trigger member 241 and the second trigger member 243 are both mounted on the second bracket 221. The first distance detection member 242 is mounted on the first bracket 211.

[0072] Preferably, the wire rope damage detection device 20 includes a plurality of elastic members 23, which are arranged in parallel and jointly support the second bracket 221. When the size of the wire rope 31 changes, the arrangement of the plurality of elastic members 23 enables the second bracket 221 and the second pulley 222 to smoothly approach or move away from the first clamping assembly 21, thereby ensuring that the first trigger member 241 / the second trigger member 243 are respectively close to the first distance detection member 242 and the second distance detection member 244, thereby ensuring the accuracy of the size detection of the wire rope 31. In this embodiment, the wire rope damage detection device 20 includes four elastic members 23. In other embodiments, three or more elastic members 23 may also be provided, which is not limited here.

[0073] Preferably, if Figure 2 As shown, the wire rope damage detection device 20 also includes a guide member 25 extending in a preset direction, and the elastic member 23 is sleeved on the guide member 25. One end of the guide member 25 is connected to the second bracket 221, and the other end is slidably matched with the housing 10. By providing the guide member 25, it can be ensured that the entire second clamping assembly 22 can accurately move in the preset direction, so that the first distance detection member 242 and the second distance detection member 244 can accurately detect the dimensional change of the wire rope 31 in the preset direction. In this embodiment, Figure 3 As shown, the guide member 25 includes a rod 251 and a stopper 252. The housing 10 is provided with a through hole 11. The rod 251 of the guide member 25 passes through the through hole 11 from the outside of the housing 10 to the inside and is fixedly connected with the second bracket 221, and the stopper 252 abuts against the outside of the housing 10. The setting of the stopper 252 can prevent the second clamping assembly 22 from getting too close to the first clamping assembly 21, thereby preventing the first distance detection member 242 and the first trigger member 241 from being pressed together with a large force and being damaged.

[0074] Preferably, if Figure 4As shown, the wire rope damage detection device 20 also includes a first half shell 271 and a second half shell 272. The first half shell 271 is arranged around the outer periphery of the first clamping assembly 21, and the second half shell 272 is arranged around the outer periphery of the second clamping assembly 22. The first half shell 271 and the second half shell 272 can protect the first clamping assembly 21 and the second clamping assembly 22, thereby preventing the external structure from affecting the position of the second clamping assembly 22, thereby ensuring the accuracy of the detection result of the distance detection assembly 24. It can be understood that in other embodiments, a housing with an integrated structure can be provided to protect the first clamping assembly 21 and the second clamping assembly 22, which is not specifically limited here.

[0075] This embodiment also provides a control method for a clothes drying machine, which is applied to the above clothes drying machine. Figure 5 As shown, the control method of the clothes drying machine includes the steps of:

[0076] Step 1, the distance detection component 24 detects the dimension D of the steel wire rope 31 clamped between the first clamping component 21 and the second clamping component 22 in a preset direction;

[0077] Step 2, the control component determines whether the size D is less than or equal to the first preset size; if so, the lifting drive source 32 stops outputting; if not, proceed to step 3;

[0078] Step 3, the control component determines whether the size D is greater than or equal to the second preset size, if so, proceeding to step 4, if not, the lifting drive source 32 works normally;

[0079] Step 4, the cleaning component 26 of the clothes drying machine cleans the steel wire rope 31;

[0080] Step 5, the control component determines whether the size D is greater than or equal to the third preset size. If so, the lifting drive source 32 stops outputting; if not, the lifting drive source 32 works normally.

[0081] The control method of the clothes drying machine in this embodiment can eliminate the influence of dirt on the wire rope 31 on the size judgment of the wire rope 31, so as to accurately confirm whether the steel wire 31 has a safety hazard, and stop the lifting drive source 32 when it is confirmed that the wire rope 31 has a safety hazard, thereby improving the safety of the clothes drying machine.
