Description

Technical Field

[0001] This application relates to the technical field of clothes drying equipment, and more particularly to a clothes drying component and a clothes drying machine. Background Technology

[0002] Clothes drying racks, as a common clothing drying device, are widely used in various living scenarios such as homes and apartment buildings. Their retractable crossbar structure can effectively expand the drying space and meet the drying needs of large quantities and types of clothing, and has become one of the mainstream design directions for clothes drying rack products.

[0003] In existing technical solutions, the connection structure between the small crossbar and the main rod of the clothes drying rack is relatively simple, lacking a self-resetting or power-driven retraction component. Adjusting the position of the small crossbar relies entirely on manual pushing and pulling. Specifically, when expanding the drying space, the small crossbar must be manually pulled outwards; when drying is complete or the clothes drying rack needs to be stored, the small crossbar must be manually pushed inwards to retract. The small crossbar itself lacks the ability to retract freely after external force is removed. This structural design has significant technical drawbacks: firstly, the entire operation requires manual intervention, resulting in poor ease of use; secondly, if the user neglects to manually retract the small crossbar, the extended crossbar will continuously occupy extra space, potentially causing structural damage by colliding with surrounding objects and reducing the clothes drying rack's compatibility in confined spaces. Summary of the Invention

[0004] The purpose of this invention is to provide a drying assembly and a clothes drying machine that can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On the one hand, a drying assembly is provided, comprising: two parallel drying rods; The crossbar mechanism includes multiple crossbars arranged along the length of the drying rod, with each end of the crossbar being slidably connected to one of the two drying rods respectively. The first power mechanism is installed on the drying rod and is connected to the crossbar via a transmission. In the unfolded state, multiple crossbars are arranged at intervals along the length of the drying rod; during the process of switching from the unfolded state to the retracted state, the first power mechanism drives one of the crossbars to move, and drives the remaining crossbars to automatically retract to the retracted position of the drying rod.

[0006] Furthermore, a bottom plate is provided on the bottom side of the end of the drying rod, and the bottom plate is used to cover the crossbar mechanism in the retracted state.

[0007] Furthermore, each end of the drying rod is provided with a bracket connection position for connecting a telescopic bracket. The bracket connection position is arranged vertically or horizontally adjacent to the retractable position, so that the base plate can cover the telescopic bracket.

[0008] Furthermore, the first power mechanism is connected to the crossbar at the foremost end of the crossbar mechanism in the unfolding direction; During the retraction process, the first power mechanism drives the connected crossbar to push the other crossbars towards the end of the drying rod and retracts it to the folded position.

[0009] Furthermore, the first power mechanism includes a power component and a transmission component. The power component is installed at or near the retracted position, and its power end is connected to the transmission component. The transmission component is connected to the crossbar.

[0010] Furthermore, the transmission assembly includes a rotating shaft that is connected to the power assembly, drums located at both ends of the rotating shaft, and two first ropes. One end of each of the two first ropes is connected to one of the two drums respectively, and the other end is connected to one of the two ends of the crossbar respectively. Alternatively, the transmission assembly includes two lead screws and two nuts. The two lead screws are respectively connected to the power assembly for transmission, and the nuts are movably mounted on the lead screws. The two nuts are connected to the two ends of the crossbar in a one-to-one correspondence.

[0011] Furthermore, a magnetic attraction structure is provided between each pair of adjacent crossbars, and the first power mechanism is connected to any of the crossbars in a transmission connection; In the recycling state, the first power mechanism drives one of the crossbars to move toward the adjacent crossbars, and after being attracted to the adjacent crossbars in sequence by the magnetic attraction structure, it is recycled to the end of the drying rod.

[0012] Furthermore, the inner side of the drying rod is provided with a sliding groove, and the end of the crossbar is slidably installed in the sliding groove; the sliding groove is provided with a slot, and the crossbar includes a rod body, a connecting part connected to both ends of the rod body, and a sliding part connected to the connecting part, the sliding part is provided in the sliding groove, and the connecting part protrudes along the slot; The connecting part and the groove are in clearance fit, and the cross-sectional length and width of the sliding part are both greater than the height of the groove.

[0013] Furthermore, it also includes a second rope, one end of which is fixed relative to the drying rod, and the other end of which is connected to the frontmost of the crossbar in the unfolding direction of the crossbar mechanism, so as to limit the maximum sliding stroke of the crossbar mechanism in the unfolded state.

[0014] Furthermore, the second rope extends along the unfolding path of the crossbar mechanism, and the second rope is provided with a plurality of connecting parts at intervals along its length direction. Each connecting part is connected to a crossbar to limit the spacing between the crossbars in the unfolded state of the crossbar mechanism.

[0015] Furthermore, when unfolded, the multiple crossbars move toward the middle of the drying rod, and at least the crossbars near the middle of the drying rod are provided with a locking structure to fix the crossbar mechanism in the unfolded state.

[0016] Furthermore, the locking structure includes a locking member disposed in the middle of the drying rod, the locking member having a first locking part, and the crossbar having a second locking part that cooperates with the first locking part for locking.

[0017] Furthermore, the first locking part is a protruding post, and the second locking part is a hook; When the crossbar is in the locked position, the inner side of the hook can abut against the protrusion and lock, thereby restricting the crossbar from moving toward the end of the drying rack; when the crossbar is in the unlocked position, the crossbar rotates along the axis under the drive of the counterweight, so that the hook deviates from the protrusion.

[0018] Furthermore, it also includes a second power mechanism, which is connected to the multiple crossbars via a linkage assembly to drive the crossbar mechanism to the unfolded state and / or drive the crossbars to the unlocked position; Alternatively, the first power mechanism is connected to the crossbar near the middle of the drying rod, and the multiple crossbars are connected by a linkage assembly. The first power mechanism drives one of the crossbars to move, and the linkage assembly drives the remaining crossbars to move toward the middle of the drying rod to the unfolded state, and / or drives one of the crossbars to move to the unlocked position.

[0019] Furthermore, the drying rod includes a fixed rod and a telescopic rod, the telescopic rod being extendable and retractable relative to the fixed rod; Among them, the multiple crossbars can move toward the middle of the fixed rod; and / or, when the telescopic rod is in the extended state, the multiple crossbars can move toward the extended end of the telescopic rod.

[0020] Furthermore, an operating part is provided on one of the crossbars near the middle of the drying rod.

[0021] Furthermore, there are two of each of the crossbar mechanism and the first power mechanism, and the two first power mechanisms are connected to the two crossbar mechanisms in a one-to-one correspondence. In the retracted state, the two crossbar mechanisms are retracted to the two ends of the drying rod respectively; in the unfolded state, the multiple crossbars of the two crossbar mechanisms move toward the middle of the drying rod respectively.

[0022] On the other hand, a clothes drying rack includes the drying components as described above.

[0023] Furthermore, it also includes a main unit and a telescopic bracket, the telescopic bracket connecting the drying rod and the main unit, a base plate being provided on the bottom side of the end of the drying rod, and a gap being formed between the bottom side of the telescopic bracket and the base plate to allow the crossbar to retract and pass through.

[0024] The beneficial effects of this application are as follows: the driving force provided by the first power mechanism can at least achieve automatic retraction of the crossbar mechanism without manual intervention, which significantly improves the ease of use; at the same time, since the first power mechanism is set to achieve automatic retraction, it avoids the situation where the crossbar is exposed during non-use time due to negligence in not retracting, ensuring the overall uniformity of the structural appearance, and can effectively prevent the crossbar from occupying space and causing collision damage.

[0028] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] Clothes drying racks, as a common garment drying device, are widely used in various residential and accommodation scenarios such as homes, apartments, and serviced apartments, and are especially suitable for the limited space on balconies in modern cities. Their retractable horizontal bar structure, with its core advantage of flexibly expanding the drying area, allows for flexible adjustment of the drying space according to the quantity and size of the clothes. It can meet the needs of flat drying of large items such as sheets and duvet covers, as well as the need for categorized drying of smaller items such as clothes and socks. This effectively solves the problem of insufficient drying capacity of traditional fixed drying racks and has become one of the mainstream design directions for current household and commercial clothes drying racks, enjoying extremely high market acceptance.

[0032] In existing technical solutions, the connection structure between the small crossbar and the main bar of a clothes drying rack generally adopts a simple sliding fit design, mostly with snap-on or grooved rail basic connections. No self-resetting components (such as reset springs or elastic pull ropes) or power-driven retraction components (such as micro motors or transmission gear sets) are set. The extension, retraction, and position adjustment of the small crossbar rely entirely on manual pushing and pulling operations. Furthermore, the sliding connection lacks precise limiting and auxiliary guiding structures, resulting in poor operation smoothness.

[0033] Specifically, when expanding the drying space, users need to pull multiple small horizontal bars outward one by one or simultaneously, allowing them to slide along the main pole's groove to the preset extension position. Some structures have high sliding resistance, requiring significant pushing force to complete the extension, and it's difficult to ensure the small horizontal bars are evenly spaced, affecting the neatness of the drying process. When drying is complete or the clothes dryer needs to be stored (e.g., for folding clothes dryer storage or to free up balcony space), the small horizontal bars also need to be manually pushed inward one by one until they fold up against the main pole, making the operation cumbersome and time-consuming. More importantly, the small horizontal bars themselves do not have the ability to retract freely after external force is removed. Once removed from manual operation, they remain in their current extended or semi-extended state and cannot autonomously return to their storage position.

[0034] The drawbacks of this structural design are particularly prominent in actual use scenarios: First, the operation process requires full manual intervention, which not only increases the burden of housework for users, but also poses a certain operational difficulty for the elderly, children and other groups with weaker physical strength to manually push and pull multiple small horizontal bars; at the same time, long-term repeated manual pushing and pulling can easily lead to increased wear at the sliding connection between the small horizontal bars and the main bar, resulting in problems such as jamming and loosening, further reducing the ease of use and product lifespan. Secondly, if the user neglects to manually retract the small horizontal bar, the extended bar will continuously occupy extra horizontal space on the balcony. On the one hand, it is very easy for it to collide and scratch with surrounding objects such as balcony doors, curtains, and washing machines, which may not only cause deformation of the small horizontal bar and damage to the main bar track, but also scratch surrounding household items. On the other hand, for small apartments and narrow balconies, the exposed small horizontal bar will significantly reduce the balcony's activity space, seriously reduce the storage compatibility of the clothes drying rack in a confined space, and even affect the normal use of the balcony's daily passage and other functions. In addition, the long-term exposed small horizontal bar is also prone to accumulating dust and being corroded by humid environments, accelerating the aging of components and affecting the product's appearance and performance.

[0035] To address the above problems, this embodiment provides a drying assembly, such as... Figures 1-6 As shown, it includes: two parallel drying rods 1, a crossbar mechanism 2, and a first power mechanism 3; the crossbar mechanism 2 includes multiple crossbars 21 arranged along the length direction of the drying rods 1, and the two ends of the crossbars 21 are slidably connected to the two drying rods 1 respectively; the first power mechanism 3 is installed on the drying rods 1 and is connected to one of the crossbars 21 in a transmission manner. In the unfolded state, multiple crossbars 21 are arranged at intervals along the length of the drying rod 1; in the retracted state, the first power mechanism 3 drives one of the crossbars 21 to move, and drives the remaining crossbars 21 to automatically retract to the end of the drying rod 1.

[0036] Based on the above solution, addressing the core deficiency of existing clothes drying racks where the small crossbar 21 relies on manual pushing and pulling and lacks autonomous retraction capability, an integrated structural design with automatic retraction as its core and flexible deployment mode is constructed through the drive of the first power mechanism 3 and the synchronous linkage of the crossbar 21. This fundamentally solves the problems of manual retraction intervention and space occupation. Its specific working logic is as follows: The component includes two parallel drying rods 1, and the crossbar mechanism 2 consists of multiple crossbars 21 distributed along the length of the drying rods 1. The two ends of the crossbars 21 respectively form corresponding sliding engagements with the two drying rods 1, ensuring that the crossbars 21 can move smoothly along the drying rods 1; the first power mechanism 3 establishes a transmission connection with one of the crossbars 21, forming a power output base point. During deployment, multiple crossbars 21 can slide along the drying rod 1 towards the central area via manual operation or automatic drive, ultimately arranging themselves at even intervals along the length of the drying rod 1, effectively expanding the drying area and meeting the drying needs of various types and large volumes of clothing. The core of the operation lies in the retrieval process. The first power mechanism 3 provides driving force, which, upon activation, drives the connected crossbars 21 to move along the drying rod 1. Through the linkage between the crossbars 21, all other crossbars 21 move synchronously, ultimately causing all crossbars 21 to converge and retract to the end of the drying rod 1. The entire process requires no manual intervention, completely eliminating the reliance on manual push-pull retrieval in existing technologies. This principle achieves automatic retrieval by replacing manual labor with power, while retaining the flexibility of the deployment method. The end-retracting structural design fundamentally solves the problems of crossbars 21 occupying space in the extended state and the pain point of sometimes being overlooked and not retracted.

[0037] The main benefits of this solution are as follows: First, it significantly improves the ease of use of the product. Through the transmission and cooperation between the first power mechanism 3 and the crossbar 21, the automatic retraction function of the crossbar mechanism 2 is realized. The entire retraction process requires no manual intervention, completely eliminating the existing technology's reliance on manual push-pull retraction mode. This effectively reduces the user's operational intensity and significantly improves ease of use compared to traditional manual structures, making it more suitable for the efficient use needs of modern homes.

[0038] Secondly, it ensures the overall structural integrity, reduces the risk of collision damage, and improves spatial adaptability. Thanks to the automatic retraction function of the first power mechanism 3, even if the user forgets to retract it, the crossbar 21 can be automatically retracted, preventing it from being exposed when not in use and ensuring the overall integrity and uniformity of the clothes drying rack's appearance. Simultaneously, the retracted crossbar 21 is centrally arranged at the end of the drying rod 1, without occupying additional space. This effectively prevents collisions with surrounding objects and structural damage caused by exposed crossbar 21, significantly improving the product's adaptability in confined living spaces such as apartments and small units.

[0039] Thirdly, it balances the functionality of drying clothes with a compact structure, enhancing the overall practicality of the product. In the unfolded state, the horizontal bar 21 slides towards the middle of the drying rod 1 and is spaced out, which can fully expand the drying area to meet the drying needs of a large number and various types of clothing; in the retracted state, it achieves compact storage, perfectly balancing the dual needs of large drying space and small storage volume, breaking through the limitations of existing technologies that make it difficult to balance functionality and storage.

[0040] In one alternative, the folding point can be set in the middle of the drying rod, and the crossbar mechanism can move to both sides to spread out the spacing.

[0041] Preferably, a base plate 4 is provided on the bottom side of the end of the drying rod 1. The base plate 4 is used to cover the crossbar mechanism 2 in the retracted state. Combined with the retraction mechanism of the drying assembly, the base plate 4 is set on the bottom side of the end of the drying rod 1, and its installation position precisely corresponds to the concentrated arrangement area of ​​the crossbar mechanism 2 after retraction. When the first power mechanism 3 drives all the crossbars 21 to be retracted to the end of the drying rod 1 simultaneously, the crossbar mechanism 2 is located in the area below the end of the drying rod 1. At this time, the base plate 4 on the bottom side of the end of the drying rod 1 can provide a complete cover for the retracted crossbar mechanism 2 from below. The base plate 4, through its fixed connection with the end of the drying rod 1, constructs a closed bottom protective structure, so that the crossbar mechanism 2, the transmission connection of the power mechanism, and other components are completely hidden in the accommodating space formed by the base plate 4 and the drying rod 1. This does not affect the retraction of the crossbar mechanism 2 into place and its next unfolding action, and also achieves physical shielding of the retracted components.

[0042] The base plate 4 structure brings multiple technical advantages to the drying assembly, further optimizing product performance and user experience: Firstly, it enhances the overall appearance and aesthetics of the product. The base plate 4 effectively conceals the exposed crossbar mechanism 2 and related connecting parts 212 in the retracted state, preventing cluttered parts from affecting the overall visual effect of the clothes dryer. This allows the clothes dryer to present a simple and neat structural form when not in use, making it more suitable for various home decoration styles. Secondly, it strengthens the protective performance of components. The base plate 4 can prevent dust, moisture, and debris from entering the connection part 212 between the crossbar mechanism 2 and the drying rod 1 and the power transmission structure from the bottom, reducing the risk of component wear and corrosion, and extending the lifespan of the crossbar. 21. Extending the service life of the sliding mechanism and power mechanism ensures the long-term stable operation of the drying assembly; thirdly, improving safety and structural compatibility, the covered crossbar mechanism 2 avoids the sharp connection part 212 being exposed, preventing users from bumping and scratching themselves when moving around on the balcony. At the same time, the enclosed bottom structure makes the clothes dryer more compact when stored, reducing the probability of interference with other items on the balcony, and further adapting to the use scenario of small spaces; fourthly, enhancing structural stability, the fixed connection between the base plate 4 and the end of the drying rod 1 can strengthen the structural strength of the end of the drying rod 1, avoiding deformation of the end of the drying rod 1 due to concentrated force after the crossbar mechanism 2 is retracted, and improving the overall structural load-bearing reliability.

[0043] Meanwhile, both ends of the drying rod 1 are respectively provided with bracket connection positions for connecting the telescopic bracket 10. The bracket connection positions are arranged vertically or horizontally adjacent to the retracted position, so that the base plate 4 can cover the telescopic bracket 10. Both ends of the drying rod 1 are pre-set with bracket connection positions, which provide basic support for the assembly and movement of the telescopic bracket 10, and can realize the detachable or integrated connection of the telescopic bracket 10, so that the telescopic bracket 10 can complete the telescopic movement along the connection position.

[0044] The bracket connection and the retractable position of the crossbar mechanism 2 adopt a compact layout of vertical or horizontal adjacent arrangement. After the crossbar mechanism 2 is retracted, it will precisely stop at the retracted position, forming a concentrated and compact area to be covered with the retracted telescopic bracket 10. The two have no spatial interference and are both located within the preset area at the end of the drying rod 1. The base plate 4, fixed to the bottom side of the end of the drying rod 1, has a coverage area that is precisely adapted to the area to be covered. Without changing the original installation position of the base plate 4 or increasing the size of the base plate, the layout design of the bracket connection and the retractable position of the crossbar enables synchronous covering of the entire telescopic bracket 10 in the retracted state and the crossbar mechanism 2 after retraction, so that both are within the coverage area of ​​the base plate 4.

[0045] Furthermore, the first power mechanism 3 is connected to a crossbar 21 near the middle of the drying rod 1; In the retracted state, the first power mechanism 3 drives one of the crossbars 21 to push the remaining crossbars 21 towards the end of the drying rod 1, and retracts it to the end of the drying rod 1. Based on the overall structure of the drying assembly, the first power mechanism 3 is not connected to the end crossbars 21, but selectively establishes a dedicated transmission connection with the outermost crossbar 21 in the crossbar mechanism 2. This outermost crossbar 21 is arranged near the middle area of ​​the drying rod 1 in the unfolded state. This connection method can form an outward-driven, step-by-step pushing retraction transmission logic. In the unfolded state, multiple crossbars 21 are arranged at intervals along the length of the drying rod 1. The outermost crossbar 21 connected to the power mechanism is located at the edge of the overall arrangement, that is, near the middle of the drying rod 1, and does not affect the drying layout of the remaining inner crossbars 21 and the hanging of clothes. When entering the recycling state, the first power mechanism 3 starts and outputs driving force, causing the outermost crossbar 21 connected to it to slide along the drying rod 1 towards the end. Since multiple crossbars 21 are arranged at intervals along the length of the drying rod 1, the outermost crossbar 21 will gradually push against the other inner crossbars 21 located between itself and the end of the drying rod 1 during the sliding process. Through the step-by-step transmission of mechanical pushing force, all crossbars 21 are driven to move synchronously towards the end of the drying rod 1 in sequence, and finally all of them are retracted to the preset position at the end of the drying rod 1, completing the recycling action. This principle, through the setting of the outermost driving point, and with the help of the pushing linkage between the crossbars 21, realizes the synchronous recycling of multiple crossbars 21 driven by a single power source, without the need to configure an independent power component for each crossbar 21.

[0046] The design of this technology, while ensuring reliable recovery, significantly optimizes the component structure and performance, offering multiple beneficial effects: Firstly, it simplifies the power transmission structure, reducing equipment costs and failure rates. By connecting a single first power mechanism 3 to the outermost crossbar 21, all inner crossbars 21 can be retracted through a pushing action, eliminating the need for multiple power components or complex linkage transmission structures. This significantly reduces the number of parts, simplifies the overall assembly process, lowers manufacturing costs, and reduces transmission nodes, effectively avoiding problems such as multi-power source coordination failures and jamming in complex transmission structures, thus improving the stability and reliability of the recovery action. Secondly, it improves recovery efficiency and synchronization, optimizing the user experience. The pushing mode driven by the outermost crossbar allows the driving force to be transmitted step-by-step along the crossbar 21 arrangement direction, avoiding problems such as delayed recovery and uneven force distribution of the far-end crossbar 21 caused by single-end driving. This ensures that multiple crossbars 21 retract synchronously towards the end, improving the smoothness and efficiency of the recovery action. Furthermore, the retracted crossbars 21 are neatly arranged, facilitating subsequent concealment by the base plate 4 and overall storage.

[0047] Furthermore, the first power mechanism 3 includes a power component and a transmission component 31. The power component is installed at the end of the drying rod 1, and its power end is connected to the transmission component 31. The transmission component 31 is connected to both ends of the crossbar 21. The power component can be a micro motor, stepper motor, etc., which is fixedly installed at the end of the drying rod 1, avoiding the movement trajectory of the crossbar mechanism 2 during unfolding and retraction, and adapting to the end structure of the drying rod 1. The power output end of the power component is rigidly connected to the transmission component 31. The transmission component 31 can adopt a lead screw, synchronous belt, transmission rod, etc., to form a power transmission link. At the same time, both ends of the transmission component 31 are respectively connected to the two ends of the outermost crossbar 21 of the crossbar mechanism 2, so that the driving force can be applied synchronously to both ends of the crossbar 21. When the recovery action is initiated, the power component outputs torque, which is transmitted synchronously to both ends of the outermost crossbar 21 through the transmission component 31, driving the crossbar 21 to slide smoothly towards the end of the drying rod 1 along the length direction of the drying rod 1. Since the transmission component 31 achieves synchronous driving at both ends, the outermost crossbar 21 is subjected to balanced force and slides smoothly. Then, through mechanical pushing action, it drives the remaining inner crossbars 21 to move synchronously towards the end of the drying rod 1, and finally completes the orderly recovery of all crossbars 21. The entire process is characterized by efficient power transmission and stable motion posture.

[0048] Specifically, the transmission assembly 31 includes a rotating shaft 311 connected to the power assembly, drums 312 located at both ends of the rotating shaft 311, and two first ropes 313. One end of each of the two first ropes 313 is connected to one of the two drums 312 respectively, and the other end is connected to one of the two ends of the crossbar 21 near the middle of the drying rod 1 respectively. The power output end of the power assembly is rigidly connected to the rotating shaft 311. The rotating shaft 311 is horizontally arranged and the drums 312 are mounted at both ends. The two first ropes 313 constitute a flexible traction component. One end of each rope is fixedly wound around one of the two drums 312 respectively, and the other end is precisely connected to one of the two ends of the outermost crossbar 21 respectively, forming a symmetrical traction structure. When the retrieval action is initiated, the power unit drives the rotating shaft 311 to rotate, causing the two end drums 312 to rotate synchronously. The rotation of the drums 312 winds and collects the first ropes 313, causing the two first ropes 313 to generate traction force synchronously. This smoothly pulls the outermost crossbar 21 from both ends of the crossbar 21 towards the end of the drying rack 1. Due to the synchronous and flexible nature of the rope traction, the crossbar 21 is subjected to balanced force and slides smoothly. Then, through mechanical pushing, the remaining inner crossbars 21 are gradually pulled together synchronously, and finally all are retrieved to the end of the drying rack 1. In the unfolded state, the drums 312 rotate in the opposite direction to release the first ropes 313. The crossbars 21 can slide towards the middle of the drying rack 1 with manual or auxiliary force. The ropes naturally stretch out with the movement of the crossbars 21, without affecting the drying space or the arrangement of the crossbars 21.

[0049] The design of this rope-type transmission component 31 not only ensures the stability of power transmission, but also leverages the flexibility of the first rope 313 to achieve significant advantages in space utilization and connection storage, forming a highly efficient synergy with the overall structure: Firstly, balanced power transmission ensures stable retrieval posture. The two first ropes 313 symmetrically connect the two ends of the crossbar 21 to the drum 312, and together with the rotating shaft 311, drive the double drums 312 to rotate synchronously, so that the traction force is applied precisely and evenly to both ends of the crossbar 21, completely avoiding problems such as tilting, jamming, and offset of the crossbar 21 caused by unilateral drive, reducing wear at the sliding connection between the crossbar 21 and the drying rod 1, ensuring smooth and regular retrieval action, and extending the service life of the component. Secondly, it occupies very little space and is suitable for compact layout requirements. The first rope 313 is made of flexible material, which can be tightly wound around the surface of the drum 312 in its natural state. When stored, its volume is minimal, requiring no additional transmission space. Compared to rigid transmission structures such as lead screws and synchronous belts, it significantly reduces the space occupied by the transmission mechanism, perfectly adapting to the installation environment at the end of the drying rod 1. Furthermore, it can be concealed by the base plate 4 along with the retracted crossbar 21 and power components, without compromising the overall compactness of the clothes dryer's structure, further enhancing its compatibility in confined spaces. Thirdly, it offers convenient connection and storage, adapting to dynamic movement needs. The rope's flexibility allows it to flexibly adapt to the installation angle between the crossbar 21 and the drum 312, eliminating the need for strict alignment with rigid installation benchmarks and reducing assembly difficulty. During retraction, the rope automatically winds around the drum 312, forming a neat and organized storage without any extra exposed parts, avoiding clutter and interference from the transmission structure. When unfolded, the rope moves smoothly and gracefully with the crossbar 21, without hindering the drying of clothes. The rope itself is bendable and foldable, ensuring that the unfolding stroke of the crossbar 21 is not affected by movement trajectory limitations. Fourthly, it synergistically enhances the overall structural adaptability. The transmission structure is highly compatible with the technical features of the power component end mounting, the base plate 4 for shielding and protection, and the outermost crossbar 21 for pushing and retracting. The drum 312 and the rotating shaft 311 can be integrated into the end of the drying rod 1, perfectly matching the enclosed space formed by the base plate 4. This not only hides the transmission components but also avoids collisions and interference with surrounding objects. At the same time, the low cost and easy maintenance of the rope transmission also reduce the overall production and maintenance costs of the equipment. Fifth, it improves the flexibility and safety of power transmission. The flexible rope can buffer the instantaneous impact force during the retrieval process, reducing the rigid impact at the connection point 212 between the power component and the crossbar 21, and reducing the probability of failure. At the same time, the rope has no sharp edges, which can prevent the exposed transmission components from scratching users or snagging clothing, thus improving the safety of use.

[0050] In one optional embodiment, the transmission assembly 31 includes two lead screws and two nuts. The two lead screws are respectively connected to the power assembly, and the nuts are movably mounted on the lead screws. The two nuts are connected one-to-one to the two ends of the crossbar 21 near the middle of the drying rod 1. The transmission assembly 31 consists of two lead screws and two nuts. The two lead screws are arranged parallel to the drying rod 1, and one end of each is synchronously connected to the power assembly. Power can be split through gear sets, couplings, etc., to ensure that the two lead screws rotate at the same speed. The nuts form a precision thread fit with the lead screws and are movably sleeved on the lead screws. At the same time, the two nuts are respectively fixedly connected one-to-one to the two ends of the outermost crossbar 21, thus constructing a symmetrical drive structure. When the retraction action is initiated, the power unit outputs torque, driving the two lead screws to rotate synchronously in the same direction. Through the threaded engagement between the lead screws and nuts, the rotational motion is converted into linear motion of the nuts along the lead screws, causing the two nuts to slide synchronously towards the end of the drying rack 1. This, in turn, pulls the outermost crossbar 21 to move smoothly. During the sliding process, the crossbar 21 pushes against the other inner crossbars 21, ultimately achieving the orderly retraction of all crossbars 21 towards the end of the drying rack 1. In the unfolded state, the power unit drives the lead screws to rotate in the opposite direction, and the nuts cause the outermost crossbar 21 to slide towards the middle of the drying rack 1. A linkage component is installed between the multiple crossbars 21, allowing them to unfold synchronously with the nut movement under the linkage of the component, forming an intermittent drying layout. The self-locking nature of the threaded engagement allows the crossbars 21 to remain stably in any unfolded position without the need for additional limiting structures.

[0051] The design of this screw-nut type transmission assembly 31 not only fits the overall structural logic but also leverages the unique technical advantages formed by the precision thread fit, enhancing the assembly's performance and practicality: Firstly, it offers high transmission accuracy and a regular, controllable recovery posture. The precise meshing of the screw and nut enables accurate positioning of linear motion. Combined with the synchronous drive of two screws, it strictly ensures the consistency of movement at both ends of the outermost crossbar 21, completely preventing tilting or offset of the crossbar 21. This ensures the crossbar 21 slides smoothly along the axis of the drying rod 1, resulting in a neat arrangement of the crossbars 21 after recovery, facilitating compatibility with the base plate 4's shielding structure. Simultaneously, it allows for precise control of the recovery stroke, preventing rigid collisions between the crossbars 21 and the ends of the drying rod 1. Secondly, it boasts strong transmission rigidity and excellent load-bearing capacity. The threaded fit structure provides excellent rigidity and load-bearing capacity, stably supporting the weight of the crossbars 21 and the clothing. It is less prone to deformation or loosening during recovery, effectively handling the combined pushing force of multiple crossbars 21, preventing deformation and failure of transmission components, extending the assembly's lifespan, and meeting the recovery needs of large items of clothing after drying. Thirdly, its excellent self-locking performance enhances safety. The screw and nut structure possesses inherent mechanical self-locking characteristics. Once the crossbar 21 is extended to any position, it can remain stably stationary without the need for additional braking components. It will not slip due to the weight of the clothes or slight external forces, ensuring stability during the drying process and avoiding the risk of collisions caused by unexpected movement.

[0052] As an optional specific implementation, a magnetic attraction structure is provided between each pair of adjacent crossbars 21, and the first power mechanism 3 is connected to any of the crossbars 21 in a transmission connection; wherein, in the retraction state, the first power mechanism 3 drives one crossbar 21 to move toward the adjacent crossbar 21, and after sequentially attracting the adjacent crossbars 21 through the magnetic attraction structure, it is retracted to the end of the drying rod 1.

[0053] Specifically, magnetic attraction structures are provided between each pair of adjacent crossbars 21. These structures can employ a combination of permanent magnets and magnetic conductive components, or a layout of two permanent magnets with opposite poles. The attraction force of the magnetic structures ensures that adjacent crossbars 21 can quickly adhere and fix themselves when close. Furthermore, in the unfolded state, the distance between the crossbars 21 is greater than the effective range of the magnetic attraction, preventing the magnetic force from interfering with the normal arrangement of the crossbars 21. The first power mechanism 3 can selectively establish a transmission connection with any crossbar 21, without limiting the position of any particular crossbar 21, thus offering greater adaptability and forming a power output base point. When entering the recycling state, the first power mechanism 3 starts and drives the connected crossbar 21 to move towards any adjacent crossbar 21. After the distance between them decreases to the effective range of magnetic attraction, they are quickly attracted and attached by the magnetic structure to form an integrated linkage unit. Subsequently, under the continuous drive of the power mechanism, the linkage unit continues to move towards the other adjacent crossbar 21, and then attracts the subsequent adjacent crossbars 21 in sequence by the magnetic structure, gradually connecting all the crossbars 21 to form a whole. Finally, the power mechanism drives all the connected crossbars 21 to move synchronously towards the end of the drying rack 1, completing the neat recycling action. When unfolding, the crossbar 21 can be manually pulled. If the external force is greater than the magnetic attraction force, the adjacent crossbars 21 can be separated and slid along the middle of the drying rack 1 to the preset interval position, thereby expanding the drying space.

[0054] In the aforementioned magnetic attraction scheme, when the first power mechanism 3 is connected to the outermost crossbar 21, the outermost crossbar 21 can drive the remaining crossbars 21 on the inner side to magnetically attach before being retracted. In this method, the first power mechanism 3 can be set to a unidirectional drive form. However, when the first power mechanism 3 is connected to any crossbar 21, including the form of connection with crossbars other than the outermost crossbar 21, before retracting all crossbars 21, all crossbars 21 need to be attracted to each other side by the magnetic attraction structure before being stored as a whole. In this case, the first power mechanism 3 needs to be designed to a bidirectional drive form so that any crossbar 21 can attract the other adjacent crossbars 21. Preferably, the inner side of the drying rod 1 is provided with a groove 11, and the end of the crossbar 21 is slidably installed in the groove 11. As the basic guide structure for the sliding of the crossbar mechanism 2, the groove 11 is opened along the length direction of the drying rod 1 on the inner side of the drying rod 1. Its groove size and cross-sectional shape are precisely matched with the end structure of the crossbar 21. The end of the crossbar 21 forms a sliding fit by embedding into the groove 11, and the groove 11 provides vertical and lateral limit to the end of the crossbar 21, allowing the crossbar 21 to slide back and forth along the extension direction of the groove 11, thus limiting the displacement of the crossbar 21 in the direction perpendicular to the drying rod 1. In the unfolded state, the crossbar 21 can slide smoothly along the slide groove 11 towards the middle of the drying rod 1. The slide groove 11 ensures that multiple crossbars 21 are always arranged along the same trajectory, forming a uniformly spaced drying layout. In the retracted state, regardless of whether the crossbar 21 is driven by a power mechanism to push, pulled by a rope, driven by a screw, or linked by magnetic attraction, the end of the crossbar 21 moves directionally along the slide groove 11, avoiding jamming or tilting due to uneven force or trajectory deviation. This ensures that all crossbars 21 can be accurately and smoothly retracted to the preset position at the end of the drying rod 1. At the same time, the limiting function of the slide groove 11 can keep the retracted crossbars 21 neatly arranged, which is convenient for matching with the covering structure of the base plate 4.

[0055] Meanwhile, the slide groove 11 is provided with a groove 111, and the crossbar 21 includes a rod body 211, a connecting part 212 connected to both ends of the rod body 211, and a sliding part 213 connected to the connecting part 212. The sliding part 213 is disposed in the slide groove 11, and the connecting part 212 extends out along the groove 111. The connecting part 212 and the groove 111 are in clearance fit, and the cross-sectional length and width of the sliding part 213 are both greater than the height of the groove 111. The groove 11 has a slot 111 along its length, with the slot 111 facing the side where the crossbar 21 is arranged. The crossbar 21 adopts a modular design, consisting of a rod body 211, a connecting part 212, and a sliding part 213. The sliding part 213 and the connecting part 212 are fixedly connected to both ends of the rod body 211. The sliding part 213 is embedded in the groove 11 to form a sliding fit. The connecting part 212 passes through the slot 111 to connect the sliding part 213 and the rod body 211, so that the rod body 211 is suspended outside the drying rod 1 to meet the needs of hanging clothes. In terms of structural design, the connecting part 212 and the slot 111 adopt a clearance fit, reserving a small amount of movement space to compensate for assembly errors and slight deformation during the sliding process, avoiding jamming caused by rigid friction. At the same time, the cross-sectional length and width of the sliding part 213 are both greater than the height of the slot 111, forming a hook-type limiting structure, which can effectively prevent the sliding part 213 from coming out of the slot 111 along the direction of the slot 111, only allowing the sliding part 213 to slide back and forth along the length direction of the slot 11. The synergistic effect of this structure is: when unfolding or retracting, the sliding part 213 moves directionally along the slot 11, and the connecting part 212 moves synchronously with the sliding part 213. The clearance fit ensures smooth movement without jamming, and the dimensional difference between the sliding part 213 and the slot 111 ensures that the crossbar 21 will not detach from the drying rod 1 throughout the process. Whether bearing the weight of the clothes, the driving force, or the impact force of magnetic linkage, it can maintain a stable fit, adapting to the operational requirements of various recycling schemes such as rope drive, screw drive, and magnetic linkage mentioned above.

[0056] Meanwhile, a plug 5 is provided at the end of the drying rod 1 to prevent the crossbar 21 from detaching from the drying rod 1 along the slide groove 11. The plug 5 is fixedly installed at the end of the drying rod 1 where the slide groove 11 is located, completely sealing the end opening of the slide groove 11. Its installation position precisely corresponds to the extreme position of the crossbar 21 after it is retracted. During the sliding process of the crossbar 21 along the slide groove 11, whether it moves towards the middle of the drying rod 1 in the unfolded state or towards the end of the drying rod 1 in the retracted state, the plug 5 does not interfere with the normal stroke of the crossbar 21. When the crossbar 21 is retracted to the preset extreme position at the end of the drying rod 1, the sliding part 213 or the connecting part 212 at the end of the crossbar 21 will form a rigid abutment with the plug 5, preventing the crossbar 21 from continuing to move outward of the slide groove 11, thus limiting the displacement range of the crossbar 21 from the end of its stroke.

[0057] In some embodiments, a second rope 6 is further included. One end of the second rope 6 is connected to the plug 5, and the other end passes through multiple crossbars 21 in sequence and is connected to a crossbar 21 near the middle of the drying rod 1 to limit the maximum sliding stroke of the crossbar mechanism 2 in the unfolded state. One end of the second rope 6 is fixedly connected to the plug 5 at the end of the drying rod 1 to form a stable limiting base point; the other end extends along the length of the drying rod 1, passes through all the remaining crossbars 21 in sequence, and has pre-set perforations at corresponding positions on the crossbars 21 to allow the rope to pass smoothly without affecting the structural strength and sliding movement of the crossbar 21 itself, and is finally fixedly connected to the outermost crossbar 21 near the middle of the drying rod 1. During the unfolding of the crossbar mechanism 2, whether manually pushed or assisted in sliding the crossbar 21 towards the center of the drying rack 1, the outermost crossbar 21 will simultaneously pull the second rope 6, gradually stretching and tightening the rope. When the crossbar 21 slides to the preset maximum stroke, the second rope 6 is fully tightened. Since one end is fixed to the plug 5 and the other end is locked to the outermost crossbar 21, a rigid constraint is formed, preventing the crossbar 21 from continuing to move towards the center, thus precisely limiting the unfolding limit position. In the retracted state, the crossbar 21 moves towards the end of the drying rack 1, and the second rope 6 naturally relaxes and folds with the displacement of the crossbar 21, storing itself between the through hole of the crossbar 21 and the slide groove 11 of the drying rack 1, without interfering with the pushing, magnetic linkage, or power-driven retraction action of the crossbar 21.

[0058] It should be noted that the second rope 6, based on the cooperation state of the slide groove 11 and the slide part 213, adopts differentiated limit logic, which not only adapts to the requirements of scenarios with good guidance, but also makes up for the guidance defects of gap cooperation or non-contact scenarios. At the same time, it forms precise coordination with the first rope 313, the crossbar 21 structure, and the plug 5, without interfering with the overall transmission and linkage recovery action.

[0059] In the first scenario, when the chute 11 and the sliding part 213 fit tightly and can fully exert their guiding and limiting functions, the second rope 6 adopts a simplified connection method, that is, one end is fixed to the end cap 5 of the drying rod 1, and the other end is directly fixed to the outermost crossbar 21, without needing to pass through multiple crossbars 21. At this time, relying on the precise guidance of the crossbars 21 by the chute 11 and the sliding part 213, the displacement of the outermost crossbar 21 can simultaneously constrain the unfolding trajectory of the other crossbars 21. The second rope 6 can indirectly control the maximum unfolding stroke of all crossbars 21 by limiting the maximum sliding distance of the outermost crossbar 21 by its own length, avoiding the crossbars 21 from over-unfolding beyond the preset range. Moreover, when retracting, the rope naturally loosens as the crossbars 21 move towards the end and is stored in the chute 11 without interference.

[0060] In the second scenario, when the slide groove 11 and the sliding part 213 have a gap fit, or when there is a non-contact gap between them resulting in insufficient guiding and limiting, the second rope 6 adopts a cooperative limiting design. That is, one end is still fixed to the plug 5, and the other end passes through the connecting part 212 of each crossbar 21 in sequence, while forming a closed limiting space with the first rope 313, so that the connecting part 212 of the crossbar 21 is precisely locked between the first rope 313 and the second rope 6. At this time, the two ropes form a clamping constraint from the top and bottom or sides, and limit the degree of freedom of the connecting part 212 by the tension of the ropes. Even if there is a gap between the slide groove 11 and the sliding part 213, it can force multiple crossbars 21 to maintain a horizontal and consistent arrangement, and prevent the crossbars 21 from tilting or misaligning. When unfolding, the two ropes stretch synchronously, and the maximum stroke is constrained by the length. When retracting, the second rope 6 relaxes and folds back into place.

[0061] Furthermore, the second rope 6 extends along the unfolding path of the crossbar mechanism 2. The second rope 6 has several connecting parts spaced apart along its length, each connecting part connecting to one of the crossbars 21, thus limiting the spacing between the crossbars 21 in the unfolded state. The second rope 6 has several connecting parts spaced at preset intervals along its length. These connecting parts employ snap-fit, binding, or integrated molding structures, corresponding one-to-one with each crossbar 21. The connection positions avoid the sliding contact area between the crossbar 21 and the drying rack 1, and do not interfere with the normal movement of the crossbar 21 along the slide groove 11. In the unfolded state, when the crossbar mechanism 2 moves towards the center of the drying rack 1, it pulls the second rope 6 to gradually tighten it. Since the rope length between each connecting part is fixed, it can force all the crossbars 21 to slide synchronously according to the spacing between the connecting parts, ultimately maintaining a preset spacing between adjacent crossbars 21 and preventing spacing disorder, offset, or stacking problems. In the retracted state, the crossbar 21 moves toward the end of the drying rod 1, the second rope 6 naturally loosens as the crossbar is retracted, and the connecting part moves synchronously with the crossbar 21 without obstructing the retraction path, ensuring that the crossbar mechanism 2 is smoothly retracted to the preset position.

[0062] In some embodiments, in the unfolded state, a locking structure is provided between the crossbar 21, at least near the middle of the drying rod 1, and the drying rod 1 to fix the crossbar mechanism 2 in the unfolded state. The locking structure effectively prevents the crossbar mechanism 2 from shaking when subjected to external force or while hanging clothes in the unfolded state, thus preventing it from retracting and ensuring stable use of the crossbar mechanism 2 in the unfolded state.

[0063] Specifically, the locking structure includes a locking member 7 located in the middle of the drying rod 1. The locking member 7 has a first locking part 71, and the crossbar 21 has a second locking part 214 that cooperates with the first locking part 71 to lock. After the crossbar mechanism 2 is extended to a preset position, the locking structure is triggered at least between the outermost crossbar 21 near the middle of the drying rod 1 and the drying rod 1. This locking structure can adopt an elastic snap-on type, an electromagnetic locking type, or a threaded locking type, etc., and forms a linkage with the sliding groove 11 and the sliding part 213 of the crossbar 21. Taking the elastic buckle type as an example, the inner side of the slide groove 11 has a pre-set slot corresponding to the unfolded position of the crossbar 21. The sliding part 213 of the crossbar 21 has an built-in elastic buckle. When the crossbar 21 slides to the unfolded limit position, the elastic buckle is inserted into the slot under the action of elastic force, forming a mechanical lock and fixing the outermost crossbar 21 in the current position. Relying on the guiding constraint of the slide groove 11 and the sliding part 213, as well as the indirect connection between the crossbars 21, the fixing of the outermost crossbar 21 can simultaneously drive the other crossbars 21 to maintain the unfolded posture, realizing the positioning of the entire crossbar mechanism 2. When it is necessary to retract, the first power mechanism 3 starts to output driving force or applies force manually. This force can overcome the elastic force of the elastic buckle, causing the buckle to disengage from the slot and unlock, or the lock can be released through the linkage of the dedicated unlocking component, ensuring that the crossbar mechanism 2 can be smoothly retracted to the end of the drying rod 1.

[0064] More specifically, the first locking part 71 is a protruding post, and the second locking part 214 is a hook. When the crossbar 21 is in the locked position, the inner side of the hook can abut against the protruding post to lock it, thus restricting the crossbar 21 from moving towards the end of the drying rack 1. When the crossbar 21 is in the unlocked position, it rotates along its axis under the drive of the counterweight 215, causing the hook to deviate from the protruding post. This locking structure adopts a purely mechanical linkage design, precisely integrated into the drying rack 1, the crossbar 21, and the existing sliding system, achieving stable locking in the unfolded state and automatic unlocking before retraction. The specific installation layout is as follows: the protruding post is fixedly installed at the limit position of the horizontal bar 21 corresponding to the inner side of the sliding groove 11 of the drying rod 1, and the protruding post extends outward perpendicular to the inner wall of the sliding groove 11; the hook is integrally formed or fixedly connected to the rod body 211 of the horizontal bar 21 near the middle of the drying rod 1, the hook has a bent structure and has a mating surface that adapts to the protruding post, and at the same time, the side of the rod body 211 facing the middle of the drying rod 1 integrates a counterweight 215, and the counterweight 215 provides driving force for the horizontal bar 21 to rotate around its own axis through the action of gravity.

[0065] During the locking process, when the crossbar mechanism 2 slides along the slide groove 11 to the extended limit position, the crossbar 21 remains horizontal, and the hook is synchronously positioned with the crossbar 21. At this time, the inner side of the hook abuts against the protrusion, forming a rigid mechanical lock. Due to the blocking effect of the protrusion on the hook, the movement of the crossbar 21 towards the end of the drying rod 1 is effectively restricted, that is, the displacement in the retraction direction is blocked. Combined with the guiding and limiting effect of the slide groove 11 and the sliding part 213, as well as the attraction effect between the crossbars 21, the entire crossbar mechanism 2 is stably positioned in the extended state, resisting the risk of slippage caused by uneven weight of clothes and slight external impact.

[0066] During the unlocking process, when the retrieval action needs to be initiated, the outermost crossbar 21 is moved a short distance towards the center of the drying rack 1 by a force. This distance is a preset maximum movement distance. This precise displacement causes the hook to initially deviate from the initial contact position of the protrusion, creating conditions for subsequent rotational unlocking. Subsequently, the counterweight 215 uses its own weight to drive the crossbar 21 to rotate around its axis, causing the hook to rotate synchronously, completely disengaging the hook from the contact range of the protrusion, thoroughly releasing the mechanical constraint between the protrusion and the hook, and completing automatic unlocking. After unlocking, the first power mechanism 3 can drive the crossbar 21 to move towards the end of the drying rack 1, thereby pulling or pushing the remaining crossbars 21, achieving the orderly retrieval of the entire crossbar mechanism 2.

[0067] In one optional embodiment, a second power mechanism is also included. This second power mechanism is connected to multiple crossbars 21 via a linkage component to drive the crossbar mechanism 2 to the unfolded state and / or drive the crossbars 21 to the unlocked position. As a functional supplement and cooperating component of the first power mechanism 3, the second power mechanism establishes a transmission connection with multiple crossbars 21 through a dedicated linkage component, constructing a dual-power collaborative architecture. This architecture can independently or simultaneously achieve automatic unfolding of the crossbar mechanism 2 and precise driving of the crossbars 21 to the unlocked position, perfectly adapting to locking structures, the sliding system of the groove 11, and various recycling schemes.

[0068] The second power mechanism can be a micro motor, stepper motor or other power component that is suitable for miniaturized installation. The linkage component can be a synchronous belt assembly, linkage rod, rope assembly or gear assembly or other structure according to the transmission requirements to ensure that the power is evenly transmitted to multiple crossbars 21.

[0069] When the drive bar mechanism 2 is in the unfolded state, after the second power mechanism is activated, the driving force is synchronously transmitted to multiple crossbars 21 through the linkage component, or the outermost crossbar 21 is driven first, and then the remaining crossbars 21 are driven by the magnetic attraction structure and the pushing action. All crossbars 21 are driven to slide smoothly along the sliding groove 11 of the drying rod 1 towards the center until they reach the maximum unfolding stroke position defined by the second rope 6. The entire unfolding process does not require manual intervention, and the linkage component can precisely control the sliding speed and spacing of the crossbars 21 to ensure that the multiple crossbars 21 are arranged horizontally and consistently. After reaching the position, the locking structure automatically locks the crossbars.

[0070] When the drive bar 21 moves to the unlocked position, and the retraction action needs to be initiated, the second power mechanism can output driving force to drive the outermost crossbar 21 to move a preset short distance towards the middle of the drying rod 1 through the linkage component. This is the limited distance required for unlocking, causing the hook to initially deviate from the protrusion abutment position. Subsequently, the counterweight 215 can be used to complete the subsequent rotational unlocking, or the second power mechanism can continue to drive the crossbar 21 to rotate around the axis, directly causing the hook to disengage from the protrusion abutment range and completely release the mechanical lock. After unlocking is completed, the second power mechanism stops working, and the first power mechanism 3 takes the lead in driving the crossbar mechanism 2 to retract towards the end of the drying rod 1, forming a closed-loop power connection from unlocking to retraction.

[0071] In addition, the second power mechanism can flexibly switch working modes according to actual needs. It can drive the unfolding action alone, in combination with manual unlocking; or drive the unlocking action alone, in combination with manual unfolding; or it can realize the automatic linkage of unfolding and unlocking simultaneously, which can fully adapt to the usage needs of different scenarios, and it does not interfere with the first power mechanism 3 and works together efficiently.

[0072] In another optional embodiment, the first power mechanism 3 is driven to the crossbar 21 near the middle of the drying rod 1. Multiple crossbars 21 are connected via a linkage assembly. The first power mechanism 3 drives one crossbar 21 to move, and through the linkage assembly, moves the remaining crossbars 21 toward the middle of the drying rod 1 to the unfolded state, and / or drives one crossbar 21 to the unlocked position. The first power mechanism 3 is driven to the outermost crossbar 21 near the middle of the drying rod 1. Multiple crossbars 21 are connected via a linkage assembly to establish a synchronous transmission relationship, ensuring that the power of a single crossbar 21 can be transmitted to all other crossbars 21. The first power mechanism 3 switches its driving direction by rotating in both directions; one direction corresponds to the retraction of the crossbar 21, and the other direction corresponds to the unfolding and unlocking positions of the crossbar 21.

[0073] When the drive bar mechanism 2 is in the unfolded state, the first power mechanism 3 switches to the reverse drive direction and outputs driving force to drive the outermost crossbar 21 connected to it to slide along the sliding groove 11 of the drying rod 1 towards the center. The driving force is synchronously transmitted to the other crossbars 21 through the linkage component, so that all crossbars 21 move smoothly in the same direction along the sliding groove 11 and form a uniformly spaced arrangement. When the outermost crossbar 21 moves to the maximum unfolded stroke limited by the second rope 6, the second rope 6 tightens to limit further displacement. At the same time, the locking structure is automatically triggered, the hook abuts against the protrusion to complete the locking, the first power mechanism 3 stops driving, and the crossbar mechanism 2 is stably maintained in the unfolded state.

[0074] When the drive bar 21 is moved to the unlocked position, and the retraction action needs to be initiated, the first power mechanism 3 first maintains a reverse drive state, driving the outermost crossbar 21 to move a preset short distance towards the middle of the drying rack 1. Through the linkage component, the crossbar 21 is precisely displaced, causing the hook to initially deviate from the contact position of the protrusion. Subsequently, the counterweight 215 uses its own weight to drive the crossbar 21 to rotate around its axis, causing the hook to completely disengage from the protrusion, thus completely releasing the mechanical lock and completing the unlocking. After unlocking, the first power mechanism 3 switches to the forward drive direction, driving the outermost crossbar 21 to move towards the end of the drying rack 1. Through the linkage component or the pushing and magnetic attraction between the crossbars 21, all crossbars 21 are synchronously retracted to the end of the drying rack 1, achieving power connection.

[0075] Throughout the process, the linkage components ensure the synchronous movement of the multiple crossbars 21 without interfering with the action of the locking structure and the limiting function of the second rope 6. The first power mechanism 3 can cover the entire process of unfolding, unlocking, and retraction without additional power components through bidirectional drive switching.

[0076] The linkage component can be a flexible connector set between two crossbars 21. The flexible connector can be a high-strength flexible rope, a wear-resistant flexible strap, or an elastic connecting rope, etc., with both ends fixedly connected to the ends of the adjacent crossbars 21. The connection position avoids the groove 111 and the locking structure to ensure that it does not interfere with the movement of each component. The first power mechanism 3 is connected to the outermost crossbar 21 near the middle of the drying rod 1. By switching the driving direction through forward and reverse operation, and relying on the pulling / conduction effect of the flexible connector, it drives all crossbars 21 to work together to complete the unfolding, unlocking, and retraction actions.

[0077] Optionally, the locking structure includes multiple locking components 7 spaced apart along the length of the drying rod 1. Each locking component 7 has a first locking part 71, and the crossbar 21 has a second locking part 214 that engages with the first locking part 71 for locking. Multiple locking components 7 are fixedly mounted at intervals along the length of the drying rod 1 inside the sliding groove 11. The spacing is preset according to the drying space requirements, covering the effective range from the end of the drying rod 1 to the maximum extension stroke, forming continuous hierarchical positioning points. Each locking component 7 is integrally formed or fixedly provided with a first locking part 71, and the crossbar 21 is correspondingly equipped with a second locking part 214. The second locking part 214 reserves space for linkage with the unlocking mechanism to ensure smooth unlocking. Compared to single-position locking, the spaced locking components 7 provide multi-level extension positioning options, allowing flexible adjustment of the crossbar 21 spacing and extension range according to the amount of clothing and drying density. It eliminates the need to extend to the maximum stroke each time, significantly improving space utilization and adapting to different apartment balcony layouts and usage scenarios.

[0078] Generally, the drying rack 1 includes a fixed rod 12 and a telescopic rod 13, the telescopic rod 13 being extendable relative to the fixed rod 12; wherein, multiple crossbars 21 can move toward the center of the fixed rod 12; and / or, when the telescopic rod 13 is in the extended state, multiple crossbars 21 can move toward the extended end of the telescopic rod 13. The fixed rod 12 serves as the core load-bearing base, its rod body 211 being an integral rigid structure, with a sliding groove 11 formed on its inner side along the length direction. This sliding groove 11 provides a stable sliding track for the crossbars 21 and also provides nesting installation space for the telescopic rod 13. The telescopic rod 13 is nested and assembled at the end of the fixed rod 12, and can freely extend and retract along the axis of the fixed rod 12 to increase or decrease the overall length of the drying rod 1. The inner side of the telescopic rod 13 is provided with an extension groove 11 that is the same size as the groove 11 of the fixed rod 12 and aligned with the axis. When the telescopic rod 13 extends or retracts, the extension groove 11 and the groove 11 of the fixed rod 12 can form a continuous sliding channel, ensuring the smooth transition and movement of the crossbar 21 on the two sections of the rod 211.

[0079] The crossbars 21 and the drying rod 1 are connected via grooves 11. Both ends of the multiple crossbars 21 are fitted into the grooves 11, allowing them to move directionally along the length of the grooves 11, with their movement trajectory consistent with the axis of the drying rod 1. The specific movement logic is as follows: First, when the telescopic rod 13 retracts to its limit relative to the fixed rod 12, the overall length of the drying rod 1 is at its shortest. At this point, the multiple crossbars 21 can move directionally along the grooves 11 of the fixed rod 12 towards the middle area of ​​the fixed rod 12, eventually converging to form a compact layout. Second, when the telescopic rod 13 extends to its target length relative to the fixed rod 12, relying on the through grooves 11, the multiple crossbars 21 can move from the area of ​​the fixed rod 12 towards the telescopic rod 13, and continue to slide along the extended grooves 11 of the telescopic rod 13 towards the middle and end areas of the telescopic rod 13, forming an unfolded layout. A basic limiting structure is provided at the end of the telescopic rod 13 to prevent the crossbars 21 from detaching from the end of the telescopic rod 13, ensuring the reliability of the structural fit.

[0080] This solution offers flexible adaptability to different drying spaces and boasts strong compatibility. Utilizing the telescopic function of the telescopic rod 13, the drying rod 1 can switch between different length ranges. Combined with the directional movement of the crossbar 21 on the fixed rod 12 and the telescopic rod 13, it can flexibly switch between compact and extended layouts according to usage scenarios, adapting to drying areas of varying widths. It is suitable for drying small quantities of clothing in confined spaces as well as meeting the needs of drying multiple garments in spacious areas.

[0081] It is worth mentioning that an operating part 8 is provided on one of the crossbars 21 near the middle of the drying rod 1. The operating part 8 is specifically designed for the manual drive of the crossbar mechanism 2. As the force carrier for manual force application, the core is precisely integrated on the single crossbar 21 near the middle of the drying rod 1. Relying on the sliding cooperation between the drying rod 1 and the crossbar 21, it realizes efficient power transmission and manual deployment of the crossbar mechanism 2. Its structural form can be adapted to actual operation requirements. It adopts an integrated or detachable structure such as a convex handle, pull handle, and anti-slip buckle. It is fixedly installed on the side or end of the crossbar 21, avoiding the sliding cooperation area between the crossbar 21 and the drying rod 1, and does not interfere with the normal movement of the crossbar 21 along the sliding groove 11 of the drying rod 1.

[0082] When manually unfolding, the user applies a directional pushing or pulling force towards the center of the drying rod 1 by gripping or manipulating the operating unit 8. This force is directly transmitted to the crossbar 21 on which the operating unit 8 is installed, causing it to slide along the sliding groove 11 of the drying rod 1 towards the center. Due to the linkage between the multiple crossbars 21, the movement of this crossbar 21 will synchronously drive the other crossbars 21 to slide in the same direction, so that the entire crossbar mechanism 2 gradually unfolds. During the unfolding process, the user can precisely control the magnitude of the applied force and the speed of movement through the operating unit 8, and stop the crossbar mechanism 2 at the preset locking position as needed to complete the positioning after unfolding; if adjustment or retraction is required, the operating unit 8 can be reversed to move the crossbar 21 towards the end of the drying rod 1 to achieve manual reset. The overall operation logic is simple and relies entirely on the cooperation of human and mechanical forces.

[0083] Preferably, there are two of each of the crossbar mechanism 2 and the first power mechanism 3, and the two first power mechanisms 3 are connected to the two crossbar mechanisms 2 in a one-to-one correspondence; wherein, in the retracted state, the two crossbar mechanisms 2 are retracted to the two ends of the drying rod 1 respectively; in the unfolded state, the multiple crossbars 21 of the two crossbar mechanisms 2 move toward the middle of the drying rod 1 respectively.

[0084] This design employs a symmetrical layout of two crossbar mechanisms 2 and two first power mechanisms 3. The core of this design utilizes a one-to-one transmission connection between the two sets of mechanisms to achieve symmetrical expansion and organized storage of the drying space. It adapts to the overall structure of the drying rod 1 and, through the coordinated control of the power mechanisms, achieves precise switching between the retracted and extended states. The two first power mechanisms 3 are independently deployed, each forming a dedicated transmission link with one of the two sets of crossbar mechanisms 2, operating independently and synchronously. The two sets of crossbar mechanisms 2 are symmetrically distributed at both ends of the drying rod 1. Each set of long rod mechanisms includes multiple crossbars 21, which precisely fit the sliding groove 11 structure of the drying rod 1, allowing for directional sliding along the groove 11.

[0085] In the retracted state, the two first power mechanisms 3 start synchronously and output corresponding driving forces, respectively driving the two sets of crossbar mechanisms 2 to move along the sliding groove 11 of the drying rod 1 to the ends of the drying rod 1 on their respective sides, until the two sets of crossbar mechanisms 2 are retracted and confined to the preset positions at both ends of the drying rod 1. At this time, the two sets of crossbar mechanisms 2 do not overlap, and the overall storage is compact, minimizing the space occupied and adapting to the storage needs after idle or small amounts of clothes have been dried.

[0086] In the unfolded state, the two first power mechanisms 3 synchronously switch driving directions, outputting reverse driving force to drive the two sets of crossbar mechanisms 2 to move synchronously and directionally along the sliding groove 11 of the drying rod 1 towards the middle of the drying rod 1. During the movement, the two sets of crossbar mechanisms 2 maintain a symmetrical arrangement, and the spacing can be controlled as needed. They eventually stop at a preset position to form a symmetrical drying layout, covering the entire length of the drying rod 1, maximizing the utilization of the drying space. The movement rhythm and stroke of the two sets of mechanisms can be kept consistent through coordinated control to ensure that the crossbars 21 are evenly arranged and have a regular posture after unfolding.

[0087] On the other hand, a clothes drying machine includes the drying components as described above, as well as a main unit 9 and a telescopic bracket 10. The telescopic bracket 10 connects the drying rod 1 and the main unit 9. A bottom plate 4 is provided on the bottom side of the end of the drying rod 1. A gap is formed between the bottom side of the telescopic bracket 10 and the bottom plate 4, allowing the crossbar 21 to be retracted and passed through.

[0088] In this scheme, the main unit 9 is the core of the overall load-bearing and control system, and is fixedly installed on the top, such as the ceiling or a pre-set position on the wall. It has a built-in control module and a mounting base for the telescopic bracket 10, which is used to provide lifting drive force and coordinate the operation logic. The two ends of the telescopic bracket 10 are fixedly connected to the main unit 9 and the drying rod 1 respectively, and the length can be extended and adjusted to realize the vertical lifting of the drying rod 1. The base plate 4 is fixed to the bottom side of the end of the drying rod 1, and is arranged horizontally. A pre-set gap of a certain size is reserved between the base plate 4 and the bottom side of the telescopic bracket 10. The width and height of this gap are adapted to the cross-sectional size of the crossbar 21 to ensure that the crossbar 21 can pass smoothly when it is retracted.

[0089] The user controls the telescopic bracket 10 to extend and retract via the main unit 9, driving the drying rod 1 to rise and fall vertically to a suitable height. When taking clothes out or putting them in, the telescopic bracket 10 extends, lowering the drying rod 1 to a height easily accessible to the user, improving convenience. When drying or storing clothes, the telescopic bracket 10 retracts, raising the drying rod 1 to the preset top position, saving space. During the raising and lowering process, the drying rod 1 remains horizontal, and the base plate 4 rises and falls synchronously with the drying rod 1, maintaining a constant gap between it and the bottom of the telescopic bracket 10, preventing interference.

[0090] In the unfolded state, the two sets of horizontal bars 21 of the drying assembly move from both ends of the drying rod 1 toward the middle and are positioned, with the clothes hanging on the horizontal bars 21; in the retracted state, the two sets of horizontal bars 21 move toward both ends of the drying rod 1 respectively, passing through the gap between the bottom plate 4 and the bottom side of the telescopic bracket 10, and finally retract to both ends of the drying rod 1 and fit against the inner side of the bottom plate 4. The gap structure effectively avoids the telescopic bracket 10 from blocking the retraction path of the horizontal bars 21, ensuring that the retraction action is smooth. At the same time, the bottom plate 4 can cover the retracted horizontal bars 21, optimizing the appearance and neatness.
