[0033] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments 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 those skilled in the art without creative work are within the scope of protection of this application.

[0034] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0035] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] The existing electric lifting clothes drying machine mainly includes a main unit and a drying rack. A driving motor and two rope reels are arranged in the main unit. The steel wire ropes on the two rope reels extend from the left and right sides of the main unit and hang down to connect the drying rack. The driving motor drives the two rope reels to rotate synchronously through the transmission, and then drives the drying rack to rise and fall through the two steel wire ropes. In the actual installation process, due to the influence of process errors or installation errors, it is easy for the steel wire ropes on both sides to extend to different lengths, which leads to different heights on the left and right sides of the suspended drying rack. This causes a problem: when retrieving the drying rack, when the higher side of the drying rack reaches the highest point and contacts the main unit first, the steel wire rope connected to the higher side of the drying rack cannot be further recovered, so the driving motor will not be able to continue to drive the two rope reels to rotate. At this time, the lower side of the drying rack has not yet reached the highest point. The recovered drying rack is in a tilted state, and the entire drying rack cannot be completely folded.

[0037] In order to overcome the above technical problems, Figure 1-2 As shown, the present embodiment provides an automatic leveling mechanism 10 for a clothes drying rack, which can be installed on the left and right sides of a clothes drying main unit 30 of a clothes drying machine. When the clothes drying rack 50 is recovered, the automatic leveling mechanism 10 for the clothes drying rack based on the present embodiment can adaptively adjust the extension lengths of the left and right hanging ropes 4 in the clothes drying main unit 30, thereby adjusting the heights of the left and right sides of the clothes drying rack 50, thereby achieving the purpose of automatically leveling the originally tilted clothes drying rack 50.

[0038] To achieve the above purpose, the automatic leveling mechanism 10 of the clothes drying rack of the present embodiment includes a pulley assembly 1 and an elastic member 2. The pulley assembly 1 can be slidably installed on the clothes drying main unit 30 to provide guidance for the hanging rope 4. The pulley assembly 1 includes a guide frame 13, and the guide frame 13 can be slidably installed on the clothes drying main unit to guide the sliding of the pulley assembly 1 in the clothes drying main unit 30; one end of the elastic member 2 is connected to the pulley assembly 1, and the other end is fixed to the clothes drying main unit 30. The elastic member 2 is used to drive the pulley assembly 1 to move in a first direction so that the pulley assembly 1 has space to slide in a second direction opposite to the first direction.

[0039] The first direction and the second direction are opposite directions, and the second direction is defined as: when the height of the drying rack 50 is kept unchanged, the pulley assembly 1 will be driven to move in the second direction during the process of the rope 4 continuing to shrink. The specific directions of the first direction and the second direction are determined by the slidable track of the pulley assembly 1 and the relative position relationship between the pulley assembly 1 and the driving device, which can be left-right direction, up-down direction, or inclined direction.

[0040] In specific application, an automatic leveling mechanism 10 for the clothes drying rack is installed on the left and right sides of the clothes drying main unit 30, and a driving device is installed in the middle of the clothes drying main unit 30. The driving device includes two rope winding wheels. The suspension ropes 4 wound around the two rope winding wheels extend from the left and right directions respectively and pass around the two pulley assemblies 1 respectively, and then extend downward to connect the clothes drying rack 50.

[0041] It can be understood that, assuming that the pulley assemblies 1 on both sides are fixedly installed, and the length of the hanging rope 4 on the left side relative to the rope reel is longer, and the length of the hanging rope 4 on the right side relative to the rope reel is shorter than that on the left side, in the normal suspension state, the drying rack 50 will be in a state where the left side is lower and the right side is higher. Since the two rope reels are driven to rotate synchronously by the same driving device, at any time, the length of the hanging rope 4 on the left side will be longer than the length of the hanging rope 4 on the right side. In the process of retrieving the drying rack 50, the right side of the drying rack 50 will first reach the highest point and contact the clothes drying main unit 30 and cannot continue to rise. The driving device cannot continue to operate, and the two rope reels stop retrieving the hanging rope 4 at the same time. At this time, the left side of the drying rack 50 has not yet reached the highest point, so the recovered drying rack 50 can only be in a tilted state.

[0042] The pulley assembly 1 of the present solution is slidably installed. When the right side of the drying rack 50 reaches the highest point first and cannot move further upward, based on the slidable freedom of the pulley assembly 1, the driving device can continue to drive the rope winding wheels on the left and right sides to rotate and retract the suspension rope 4. The extended length of the suspension rope 4 on the right side continues to shorten. During the shortening process, the pulley assembly 1 is pushed to slide in the second direction. At the same time, the height of the right side of the drying rack 50 remains unchanged, that is, the pulley assembly 1 adapts to the continued shortening of the suspension rope 4 on the right side through its own sliding; during the process of continued shortening of the suspension rope 4 on the left side, it will continue to drive the left side of the drying rack 50 to rise, so that the left side of the drying rack 50 can also reach the highest point, and finally achieve the purpose of automatically leveling the drying rack 50.

[0043] Since the end of the hanging rope 4 is connected to the drying rack 50, the drying rack 50 will drive the hanging rope 4 to droop under the gravity of the drying rack 50. Assuming that the sliding of the pulley assembly 1 in the drying rack 50 is not restricted, the drying rack 50 will freely droop to the lowest position. At this time, the pulley assembly 1 in the drying rack 50 will not be able to adapt to the continued recovery of the hanging rope 4 by sliding itself. Therefore, the present solution is provided with an elastic member 2, and the elastic force applied by the elastic member 2 to the pulley assembly 1 is in the direction of driving the pulley assembly to move in the first direction. When the drying rack 50 has not reached the highest point, the elastic member 2 pushes the pulley assembly 1 to slide in the first direction to lift the drying rack 50, so as to provide sufficient space for the pulley assembly 1 to slide in the second direction later. When the drying rack 50 is lifted to the highest point, the pulley assembly 1 has enough sliding space to adapt to the continued recovery of the hanging rope 4.

[0044] In this solution, the pulley assembly 1 is provided with a guide frame 13 to guide its sliding in the clothes drying main unit 30, which can ensure the sliding stability of the pulley assembly 1. The connection between the guide frame 13 and the clothes drying main unit 30 can be provided with mutually cooperating slide rails + slide grooves, slide holes and other structures.

[0045] In summary, based on the automatic leveling mechanism 10 of the clothes drying rack of the present embodiment, the pulley assembly 1 for guiding the hanging rope 4 is provided with a guide frame 13, and the guide frame 13 can be slidably installed in the clothes drying main unit 30. When the clothes drying rack 50 is folded up, when the two sides of the clothes drying rack 50 are of different heights and the higher side reaches the highest point first, the driving device in the clothes drying main unit 30 can continue to recycle the hanging rope 4. In the process of continuing to recycle the hanging rope 4, while keeping the height of the higher side of the clothes drying rack 50 unchanged, the continuously shortened hanging rope 4 can adapt to push the pulley assembly 1 to slide to provide sufficient recovery of the hanging rope 4; and the side of the clothes drying rack 50 that has not reached the highest point can continue to be pulled up by the hanging rope 4 on the other side, so that both sides of the clothes drying rack 50 can eventually reach the highest point of recovery, thereby achieving the purpose of leveling and completely folding the clothes drying rack 50. In addition, the present solution also provides an elastic member 2 for the sliding pulley assembly 1, and the elastic member 2 can continuously provide the pulley assembly 1 with a stable elastic force. When the drying rack 50 has not reached the highest point, the elastic member 2 can drive the pulley assembly 1 to move in the first direction, so that the pulley assembly 1 has space to slide in the second direction, and provide sufficient sliding adjustment space for the pulley assembly 1 to adapt to the continued recovery of the suspension rope 4 in the later stage, so as to meet the purpose of adaptively adjusting the extended length of the suspension rope 4 and finally leveling the drying rack 50.

[0046] In one embodiment, referring to Figure 1-2 The elastic member 2 includes a spring, one end of which is fixed to the clothes drying main unit 30 and the other end of which is connected to the pulley assembly 1.

[0047] The spring is used as the elastic member 2 to directly connect the clothes drying main unit 30 and the pulley assembly 1. While meeting the functional requirements, the spring has the advantages of simple structure, low cost, and easy installation. In specific implementation, hooks are provided at both ends of the spring, which are respectively hung on the clothes drying main unit 30 and the pulley assembly 1 through the hooks.

[0048] In other embodiments, the elastic member 2 may also be a structure such as an elastic support or an elastic sleeve with elastic expansion and contraction function.

[0049] In one embodiment, referring to Figure 1 The pulley assembly 1 further includes a roller 11 and an axle 12 , wherein the axle 12 is connected to the guide frame 13 , and the roller 11 is rotatably mounted on the axle 12 .

[0050] The pulley assembly 1 is provided with a roller 11 and an axle 12, and the axle 12 provides support for the rolling of the roller 11, so that the roller 11 can be reliably installed. The axle 12 is connected to a guide frame 13, and the sliding of the guide frame 13 drives the translation of the roller 11 to realize the automatic leveling function.

[0051] In one embodiment, referring to Figure 2 The wheel axle 12 includes a sliding mounting portion 122 and a rotating mounting portion 121. The sliding mounting portion 122 is slidably mounted on the clothes drying host 30 to limit the freedom of rotation of the wheel axle 12 relative to the clothes drying host 30; the roller 11 is rotatably mounted on the rotating mounting portion 121.

[0052] The sliding mounting portion 122 of the wheel axle 12 is used for sliding mounting on the clothes drying mainframe 30. It is usually matched with the slide rail or slide groove on the clothes drying mainframe 30 to ensure that the wheel axle 12 can slide smoothly along the predetermined path. This design limits the freedom of rotation of the wheel axle 12 relative to the clothes drying mainframe 30, so that the pulley assembly 1 can only slide along the preset track on the clothes drying mainframe 30, thereby ensuring the stability and controllability of the movement of the pulley assembly 1. The rotating mounting portion 121 is used for rotating the roller 11. When the hanging rope 4 slides on the roller 11, the roller 11 can rotate smoothly, reducing the friction between the hanging rope 4 and the roller 11, thereby ensuring the stability and smoothness of the clothes drying rack during the lifting process.

[0053] In one embodiment, referring to Figure 3 and Figure 7 The clothes drying host 30 includes a host frame 3, and the host frame 3 is provided with a pulley installation opening 31 for avoiding the roller 11. The host frame 3 is provided with two pulley support plates 32 located on two opposite sides of the pulley installation opening 31, and the wheel axle 12 is slidably installed on the pulley support plates 32.

[0054] The host frame 3, as the main frame structure of the clothes drying host 30, not only supports and fixes the various components of the clothes drying host 30, but also provides a pulley installation port 31 for avoiding the movement of the roller 11 during the lifting process, so that the pulley assembly 1 can be installed inside the host frame 3 to be hidden, and the suspension rope 4 can extend to the outside of the host frame 3 through the pulley installation port 31 and hang down to connect the drying rack 50, so as to achieve stable installation of the pulley assembly 1. On the two opposite sides of the pulley installation port 31, the host frame 3 is provided with pulley support plates 32, and the two pulley support plates 32 are used to support the wheel axle 12 to ensure that the wheel axle 12 can slide smoothly on the predetermined track. The design of the pulley support plates 32 should take into account the size and shape of the wheel axle 12, as well as the movement trajectory and sliding range required when the wheel axle 12 slides.

[0055] In one embodiment, referring to Figure 4 The pulley support plate 32 includes a pulley support portion 321 and an elastic member fixing portion 322 which are at an angle to each other. The pulley support portion 321 is provided with a sliding hole 323, and the wheel axle 12 is slidably installed in the sliding hole 323. One end of the elastic member 2 is fixed to the elastic member fixing portion 322, and the other end is connected to the wheel axle 12.

[0056] In the specific configuration, the two pulley support parts 321 are arranged in parallel, and the two elastic member fixing parts 322 extend in separate directions. The elastic member 2 can be installed on the side of the pulley support part 321 facing away from the roller 11, which can avoid the problem of interference friction between the rotating roller 11 and the elastic member 2, and maintain the stability of the installation of the roller 11 and the elastic member 2. The two ends of the axle 12 extend out of the pulley support part 321 respectively, and the elastic member fixing part 322 at an angle with the pulley support part 321 can just provide a fixing point for the elastic member 2, thereby realizing the installation of the elastic member 2.

[0057] In one embodiment, the guide frame 13 is slidably connected to the pulley support plate 32 to guide the translation of the pulley assembly 1 .

[0058] The pulley support plate 32 used to support the wheel axle 12 is also used as a structure for installing the guide frame 13. Without adding an additional guide structure, the pulley support plate 32 provides a stable sliding track for the guide frame 13, ensuring the stability and accuracy of the pulley assembly 1 during the translation process. Therefore, this solution simplifies the structure of the main frame 3.

[0059] In one embodiment, referring to Figure 2The guide frame 13 includes two side guard plates 131 arranged in parallel on both sides of the roller 11. One end of each of the two side guard plates 131 is rotatably connected to the wheel shaft 12, and the other end is fixedly connected to an anti-jumping wire plate 133. The anti-jumping wire plate 133 is located on the peripheral side of the roller 11 to prevent the suspension rope 4 from escaping from the wheel groove on the roller 11. At least one of the two side guard plates 131 is provided with a guide plate 132. The pulley support plate 32 is provided with a guide hole 324 for guiding the guide plate 132. The guide plate 132 is embedded in the guide hole 324. The two side guard plates 131 are respectively located on both sides of the roller 11 and connected to the wheel shaft 12. The guide plate 132 is provided on the side of the side guard plate 131 facing away from the roller 11 to provide guidance. This design enables the roller 11 to maintain a stable posture when sliding. At the same time, the guide hole 324 provided on the pulley support plate 32 provides a space for the guide plate 132 to be embedded, so that the guide plate 132 can slide smoothly in the guide hole 324, thereby guiding the translation of the pulley assembly 1.

[0060] The anti-jump wire plate 133 is located on the peripheral side of the roller 11, and its main function is to prevent the hanging rope 4 from accidentally escaping from the wheel groove on the roller 11. During the operation of the clothes drying machine, the change in the tension of the hanging rope 4 may cause the position of the hanging rope 4 on the roller 11 to change, and even escaping from the wheel groove. The presence of the anti-jump wire plate 133 can effectively prevent this from happening, thereby ensuring the normal operation of the clothes drying machine.

[0061] In one embodiment, referring to Figure 4 The guide hole 324 includes a first hole position 3241 and a second hole position 3242, wherein the first hole position 3241 is provided at the elastic member fixing portion 322, and the second hole position 3242 is provided at the pulley supporting portion 321, and the first hole position 3241 and the second hole position 3242 are connected at the connection between the elastic member fixing portion 322 and the pulley supporting portion 321, and the size of the first hole position 3241 is not less than the size of the guide plate 132, so that the guide plate 132 can slide into the second hole position 3242 through the first hole position 3241.

[0062] Specifically, the structure of the guide hole 324 is as follows: Figure 4 During assembly, the guide plate 132 of the entire guide frame 13 can be directly aligned with the first hole 3241 and then inserted from top to bottom between the two pulley support plates 32, while allowing the guide plate 132 to be directly placed in the second hole 3242, and using the second hole 3242 to guide the remaining sliding of the guide frame 13; after the guide frame 13 is installed, the roller 11 is installed inside the guide frame 13, and then the wheel axle 12 is installed and the elastic member 2 is installed. Obviously, this structure has the advantage of convenient installation, and can also avoid the problem of interference between the installed guide frame 13 and the elastic member 2.

[0063] In one embodiment, a avoiding gap 1331 is provided in the middle of the anti-jump wire plate 133 , and the periphery of the roller 11 is embedded in the avoiding gap 1331 .

[0064] A avoiding notch 1331 is provided in the middle of the anti-jumping wire plate 133 so that the periphery of the roller 11 can be embedded, which can lower the height of the anti-jumping wire plate 133 and make the structure of the entire pulley assembly 1 more compact. At the same time, the structure on both sides of the avoiding notch 1331 can be used to completely confine the suspension rope 4 in the wheel groove on the roller 11.

[0065] On the other hand, the present embodiment also provides a clothes drying machine, including a clothes drying main unit 30 and a clothes drying rack 50, wherein the above-mentioned automatic leveling mechanism 10 for the clothes drying rack is respectively arranged on two opposite sides of the clothes drying main unit 30; a driving device is installed in the middle of the clothes drying main unit 30, and the driving device includes two rope winding wheels, and the suspension ropes 4 wound around the two rope winding wheels extend from two opposite directions respectively and respectively bypass the two automatic leveling mechanisms 10 for the clothes drying rack and then extend downward to connect with the clothes drying rack 50.

[0066] Based on the automatic leveling mechanism 10 of the drying rack of this embodiment, the clothes drying machine of this embodiment can adaptively level the drying rack 50 when retrieving the drying rack 50, thereby avoiding the tilting of the recovered drying rack 50 and achieving the purpose of fully folding the drying rack 50.

[0067] In one embodiment, the two sides of the clothes drying main unit 30 on which the automatic leveling mechanism 10 of the clothes drying rack is installed are respectively installed with travel switches, and the travel switches are used to detect the lifting height of the two sides of the clothes drying rack 50.

[0068] Specifically, the travel switch and the driving device are connected to the control center of the clothes drying machine, and the travel switches on both sides respectively feedback whether the two sides of the drying rack 50 are lifted to the highest position. When the travel switches on both sides detect the drying rack 50, it means that the drying rack 50 is completely leveled and completely folded, and the operation of the driving device can be automatically stopped at this time. Therefore, the setting of the travel switch of this solution can ensure that the drying rack 50 is completely folded.

[0069] In one embodiment, referring to Figure 8-9 The drying rack 50 is installed with a fixing frame 5, and the fixing frame 5 is provided with a connected through hole 51 and a limiting hole 52; the end of the hanging rope 4 is connected with a rope head 41, the aperture of the through hole 51 is larger than the size of the rope head 41, and the aperture of the limiting hole 52 is smaller than the size of the rope head 41, and the rope head 41 is limited to the lower side of the limiting hole 52, and the through hole 51 is installed with a blocking member for limiting the rope head 41 from sliding in.

[0070] During installation, the rope end 41 of the hanging rope 4 passes through the hole 51 from top to bottom and then moves horizontally to the bottom of the limiting hole 52, and then the hole blocking member blocks the hole 51, restricting the rope end 41 below the limiting hole 52, thereby realizing a reliable connection between the hanging rope 4 and the drying rack 50. Obviously, this structure has the advantage of simple assembly and disassembly. Among them, the hole blocking member is preferably a bolt, and the limiting hole 52 is a matching threaded hole.
