Description

Technical Field

[0001] This invention relates to the field of clothes drying rack technology, and in particular to a staggered cross-type quilt drying rack unfolding structure, unfolding method, and clothes drying rack having the quilt drying rack unfolding structure. Background Technology

[0002] As a common appliance in modern homes, the rational layout and efficient utilization of drying space in electric clothes drying racks has always been a key focus of the industry. In scenarios where clothes and bedding are dried simultaneously, how to avoid spatial interference between the clothesline and the bedding drying line, achieving simultaneous drying without mutual interference, is a technical problem that current technology urgently needs to solve.

[0003] Patent application CN119711132A discloses a layered drying rack assembly and clothes drying machine. It employs a structure where a first main drying rack, a second main drying rack, a first quilt drying rack assembly, and a second quilt drying rack assembly cooperate with each other. The quilt drying rack is extended and retracted via a hinged connection of a telescopic rod. In use, the distance between the quilt drying rack and the main drying rack can be adjusted; in the retracted state, the quilt drying rack rests against the outside or inside of the main drying rack. While this technical solution can achieve layered drying of clothes and bedding to a certain extent, the quilt drying rack and the main drying rack are always parallel to each other, leading to a risk of interference in the lateral space, and it occupies a large lateral space when retracted.

[0004] Utility model patent CN219972759U discloses a drying assembly that allows clothes and quilts to be dried simultaneously. It expands the drying space through a laterally movable drying rod and a rotatable quilt drying rod. When unfolded, the quilt drying rod is positioned in the middle of the lower side of two longitudinally fixed rods, while the movable drying rod extends laterally outward to increase the lateral distance between the clothes drying rod and the quilt drying rod. Although this technical solution achieves independent drying of clothes and quilts through lateral expansion, it still essentially relies on the parallel arrangement of the quilt drying rod and the clothes drying rod. This requires increasing the overall width of the clothes rack to achieve spatial separation, resulting in an increase in the overall size of the clothes drying machine. Furthermore, the unfolded quilt drying rod, located in the middle of the two clothes drying rods, occupies the drying space in the middle area below the clothes drying rods, restricting the normal drying of clothes in that area.

[0005] The aforementioned existing technical solutions have the following common defects: First, both the quilt drying rod and the clothes drying rod remain parallel when extended, resulting in an overlapping area on the longitudinal projection plane, making it easy for clothes and quilts to come into contact with or block each other during the drying process; Second, to prevent clothes and quilts from interfering with each other, existing technologies usually adopt the method of horizontally expanding the overall width or vertically lengthening the hanging distance. The former results in a bulky clothes drying machine, while the latter places the clothes drying rod and the quilt drying rod at different heights, compressing the drying space of the upper clothes drying rod and making it impossible to dry longer items such as long skirts, windbreakers, and long down jackets; Third, existing structures often only allow for a space allocation pattern of drying quilts on one side and clothes on the other side, preventing users from flexibly arranging items for drying in the drying area according to their actual needs.

[0006] Therefore, there is an urgent need for a drying rack unfolding structure that can achieve a staggered and cross arrangement of quilt drying racks and clothes drying racks without increasing the overall width of the clothes drying rack or compressing the drying space of the clothes drying rack, so that clothes and quilts can be dried together without interfering with each other. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a staggered, cross-shaped quilt drying rack unfolding structure, unfolding method, and clothes drying machine. It aims to solve the interference problem caused by the parallel arrangement of quilt and clothes drying racks in existing clothes drying machines. This invention overcomes the technical defects of existing technologies, such as the large size of the clothes drying machine, limited drying space on the drying racks, inability to dry long garments, and rigid allocation of drying space, resulting from horizontally expanding the overall width or vertically lengthening the hanging distance. The invention achieves true non-interference in space when clothes and quilts are dried together, with minimal difference in drying height between clothes and quilts, allowing users to dry garments of different lengths freely within the drying area.

[0008] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a staggered cross-type quilt drying rod unfolding structure, including: a clothes drying rod assembly having a clothes drying area extending along a first direction; A quilt drying rod assembly is movably connected to the clothes drying rod assembly and has a folded-in state and an unfolded state; In the retracted state, the quilt drying rod assembly is folded up above the clothes drying rod assembly; In the unfolded state, the quilt drying rod assembly is located below the clothes drying rod assembly, and the extension direction of the quilt drying rod assembly intersects with the first direction to form a staggered drying space.

[0009] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the clothes drying rod assembly includes a front clothes drying rod and a rear clothes drying rod arranged at intervals, and a clothes drying rod connecting plate connecting the front clothes drying rod and the rear clothes drying rod; The quilt drying rod assembly includes a left quilt drying rod assembly and a right quilt drying rod assembly; In the unfolded state, the left and right clothes drying rod assemblies are parallel and close together, and are both perpendicular to and below the front and rear clothes drying rods.

[0010] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: both the left quilt drying rod assembly and the right quilt drying rod assembly include a first quilt drying rod body, a quilt drying rod connecting rod, and a second quilt drying rod body; The front end of the quilt drying rod connecting rod is rotatably hinged to the rear end of the first quilt drying rod body, and the rear end of the quilt drying rod connecting rod is rotatably hinged to the front end of the second quilt drying rod body. In the retracted state, the first quilt drying rod, the quilt drying rod connecting rod, and the second quilt drying rod are bent and close together above the clothes drying rod assembly; the quilt drying rod connecting rod of the left quilt drying rod assembly is close together above the clothes drying rod connecting plate on the left side, and the quilt drying rod connecting rod of the right quilt drying rod assembly is close together above the clothes drying rod connecting plate on the right side; the first quilt drying rod and the second quilt drying rod are respectively folded up on the upper side of the corresponding front clothes drying rod and the rear clothes drying rod; During the conversion process, the first and second quilt drying rods rotate horizontally relative to the quilt drying rod connecting rod, so that the first quilt drying rod, the quilt drying rod connecting rod, and the second quilt drying rod extend to be collinear, and then the whole assembly flips downwards to be below the clothes drying rod assembly.

[0011] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: both the first quilt drying rod and the second quilt drying rod are telescopic rods, including an outer rod and an inner rod telescopically disposed within the outer rod; In the unfolded state, the inner rod can extend from the outer rod to increase the length of the quilt drying rod assembly; a limiting member is provided between the inner rod and the outer rod to prevent the inner rod from retracting.

[0012] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: it further includes a pull rope and a winding device; the winding device is disposed on the clothes drying rod assembly; One end of the pull rope is wound inside the take-up device, and the other end is connected to the end of the quilt drying rod assembly; In the unfolded state, the pull rope is pulled out and tensioned, forming a triangular support structure with the quilt drying rod assembly; There are two clothesline winding devices, which are respectively installed on the front clothesline and the rear clothesline.

[0013] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is: the upper surface of the clothes drying rod connecting plate is provided with a protruding structure; The lower surface of the quilt drying rod connecting rod is provided with a concave cavity structure that mates with the protruding structure; In the folded state, the protruding structure enters the concave cavity structure to position the quilt drying rod assembly.

[0014] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a pushing component is provided between the rear end of the first quilt drying rod and the front end of the quilt drying rod connecting rod, and between the front end of the second quilt drying rod and the rear end of the quilt drying rod connecting rod; The actuating component includes a movable component and a flexible actuating component; When the first or second quilt drying rod body rotates to be collinear with the quilt drying rod connecting rod, the elastic pusher pushes the movable part to cooperate with the protruding structure to lift and separate the quilt drying rod connecting rod from the clothes drying rod connecting plate.

[0015] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is: the elastic pushing member rotates with the first drying rod or the second drying rod; The movable component is disposed inside the connecting rod of the quilt drying rod, and the protruding structure is provided with a guide slope that cooperates with the movable component; When the first or second quilt drying rod body rotates to be collinear with the quilt drying rod connecting rod, the elastic pusher rotates to be collinear with the movable part, and the elastic pusher pushes the movable part with its ends abutting each other. The movable part cooperates with the guide slope of the protruding structure to lift and separate the quilt drying rod connecting rod from the clothes drying rod connecting plate.

[0016] Another technical solution adopted by the present invention to solve the above-mentioned technical problem is: a method for unfolding a quilt drying rack based on a staggered cross-type quilt drying rack unfolding structure, characterized in that: Includes the following steps: Step S1: Rotate the quilt drying rod assembly that is gathered above the clothes drying rod assembly so that the segments of the quilt drying rod assembly extend from the bent state to the collinear state. Step S2: Flip the quilt drying rod assembly, which is extended in a collinear state, downwards so that it moves below the clothes drying rod assembly and the extension direction of the quilt drying rod assembly intersects with the extension direction of the clothes drying rod assembly. Step S3: Stretch the telescopic part of the quilt drying rod assembly outward to the required length and lock it with the limiting piece to complete the unfolded state.

[0017] Another technical solution adopted by the present invention to solve the above-mentioned technical problems is: a clothes drying rack, including a main unit, a lifting device and a drying assembly, wherein the drying assembly is a staggered cross-type clothes drying rod unfolding structure, and the clothes drying rod assembly is connected to the main unit through the lifting device.

[0018] Compared with the prior art, the advantages of the present invention are: First, the staggered, intersecting layout fundamentally solves the problem of clothing and bedding interference. This invention creates a staggered, intersecting drying space by setting the extension direction of the quilt-drying rod assembly to intersect with the extension direction of the clothes-drying rod assembly in its unfolded state. This fundamentally solves the problem in existing technologies where clothes and quilts overlap and block each other on the longitudinal projection plane due to the parallel arrangement of quilt-drying and clothes-drying rods, truly achieving spatial non-interference when clothes and quilts are dried together.

[0019] Secondly, the appropriate height difference design balances a compact structure with the ability to dry long garments. The staggered, cross-layered layout of this invention eliminates the need to horizontally expand the overall width of the machine or excessively lengthen the hanging distance to avoid interference between the quilt drying rod and the clothes drying rod. This allows for a suitable height difference between the two, ensuring a compact structure and minimal increase in size while providing ample drying height below the clothes drying rod. This allows for the normal drying of long garments such as long skirts and trench coats, overcoming the shortcomings of existing technologies that are bulky or compress the upper drying space.

[0020] Third, the cross-structure breaks the fixed space allocation pattern. This invention, through the cross-layout of the quilt-drying rod assembly and the clothes-drying rod assembly, breaks the traditional fixed space allocation pattern of drying quilts on one side and clothes on the other. In the unfolded state, users can freely hang clothes and quilts at any location within the entire drying area, achieving flexible allocation and free combination of drying space, significantly improving space utilization and user convenience.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 6 The clothes drying rack 300 shown in this embodiment includes a main unit 301, a lifting device 302, and a drying assembly 200. The drying assembly 200 is the staggered, cross-type quilt drying rod unfolding structure 100 provided by this invention. The clothes drying rod assembly 10 is connected to the main unit 301 via the lifting device 302 and can move up and down under the drive of the lifting device 302, facilitating the user's drying of clothes and quilts. In other embodiments, the lifting device 302 can be a folding frame as in this embodiment, a combination of a folding frame and a steel wire rope, or simply a steel wire rope, etc.

[0025] like Figures 1 to 6 As shown, the staggered cross-type quilt drying rod unfolding structure 100 provided in this embodiment mainly includes a clothes drying rod assembly 10 and a quilt drying rod assembly 20 movably connected to the clothes drying rod assembly 10.

[0026] The clothesline assembly 10 has a drying area extending along a first direction. In this embodiment, the first direction refers to the length direction of the clothesline, i.e., the left-right lateral direction when the user faces the clothes drying machine. The clothesline assembly 10 includes a front clothesline 11 and a rear clothesline 12 spaced apart, and a clothesline connecting plate 13 connecting the front clothesline 11 and the rear clothesline 12. The front clothesline 11 and the rear clothesline 12 are parallel to each other and together define the rectangular drying area extending along the first direction, providing ample lateral hanging space for drying clothes. There are two clothesline connecting plates 13, which are fixedly installed at the left and right ends of the clothesline assembly 10, respectively. The clothesline connecting plates 13 not only securely connect the front clothesline 11 and the rear clothesline 12 to form a rigid frame structure, but also serve as the base for the installation and storage of the clothesline assembly 20, and contribute to the stability of the entire device. The clothes drying rod connecting plate 13 serves three functions simultaneously: connection, support, and installation foundation. This multi-purpose design reduces the number of parts, simplifies the assembly process, and helps reduce material and manufacturing costs.

[0027] like Figures 1 to 6 As shown, the quilt drying rod assembly 20 is movably connected to the clothes drying rod assembly 10 and has a retracted state and an extended state. In the retracted state, the quilt drying rod assembly 20 is completely folded up above the clothes drying rod assembly 10. At this time, the clothes drying rack 300 has a compact shape and a neat appearance, without taking up extra space on the user's balcony. In the extended state, the quilt drying rod assembly 20 is flipped downwards and located below the clothes drying rod assembly 10, and the extension direction of the quilt drying rod assembly 20 is perpendicular to the first direction to form a staggered drying space.

[0028] The "staggered layering" mentioned here refers to the spatial layout where the quilt drying rod assembly 20 and the clothes drying rod assembly 10 are at different heights, forming a staggered layering; and on the horizontal projection plane, their extension directions intersect, rather than being parallel. This layout ensures that on the vertical projection plane, the quilt drying rod assembly 20 only overlaps with the front clothes drying rod 11 and the rear clothes drying rod 12 at several points, rather than the entire surface overlap caused by parallel rods in existing technologies. This fundamentally solves the problem of interference such as clothing and quilts easily contacting and blocking each other during the drying process. At the same time, the staggered layering design allows the quilt drying rod and the clothes drying rod to be at an appropriate height difference, without excessively lengthening the hanging distance of the quilt drying rod to avoid interference. This ensures sufficient vertical space below the clothes drying rod, allowing for the normal drying of long-sized garments such as long skirts, windbreakers, and long down jackets, overcoming the shortcomings of existing technologies that compress the upper drying space or result in a large overall size of the clothes drying machine. Furthermore, the cross-layout breaks the fixed space allocation pattern of traditional solutions where quilts are dried on one side and clothes are dried on the other. Users can hang clothes and quilts anywhere in the entire drying area, realizing flexible allocation and free combination of drying space, and significantly improving space utilization.

[0029] In this embodiment, the extension direction of the quilt drying rod assembly 20 is preferably perpendicular to the first direction to form a cross-shaped, staggered drying space. Compared to other non-parallel, oblique cross-shaped forms, the mutually perpendicular cross-shaped structure can achieve full-width coverage of the entire drying area with the shortest quilt drying rod span within the rectangular drying area, resulting in the highest space utilization. Furthermore, the weight of the quilt is evenly distributed to multiple support points on the front and rear drying rods through the quilt drying rod assembly, ensuring balanced force distribution, no off-center load, and superior structural stability.

[0030] like Figures 1 to 6 As shown, to achieve the above functions, the quilt drying rod assembly 20 specifically includes a left quilt drying rod assembly 20a and a right quilt drying rod assembly 20b. In the unfolded state, the left and right quilt drying rod assemblies 20a and 20b are parallel to each other and close together, both perpendicular to the front and rear clotheslines 11 and 12, and located beneath them. This parallel and close design of the two sets of quilt drying rod assemblies 20 allows them to jointly support a heavy quilt, providing stable support; alternatively, they can be used to drape different items, offering flexibility and versatility.

[0031] Specifically, the left and right quilt drying rod assemblies 20a and 20b are structurally symmetrical, each including a first quilt drying rod body 21, a quilt drying rod connecting rod 22, and a second quilt drying rod body 23. The front end of the quilt drying rod connecting rod 22 is rotatably connected to the rear end of the first quilt drying rod body 21 via a hinge shaft 53, and the rear end of the quilt drying rod connecting rod 22 is also rotatably connected to the front end of the second quilt drying rod body 23 via a hinge shaft 53. This three-section hinged structure allows the quilt drying rod assembly 20 to be compactly folded in the stored state and fully extended in the unfolded state.

[0032] as shown in Figure 2 and Figure 3 , in the stored state, the first quilt drying rod body 21, the quilt drying rod connecting rod 22 and the second quilt drying rod body 23 are in a bent state and close to the upper side of the clothes drying rod assembly 10. Specifically, the quilt drying rod connecting rod 22 of the left quilt drying rod assembly 20a is close to the upper side of the left clothes drying rod connecting plate 13, and the quilt drying rod connecting rod 22 of the right quilt drying rod assembly 20b is close to the upper side of the right clothes drying rod connecting plate 13. The first quilt drying rod body 21 and the second quilt drying rod body 23 are respectively folded on the upper sides of the corresponding front clothes drying rod 11 and rear clothes drying rod 12. At this time, the entire quilt drying rod assembly 20 is in a shape similar to a Chinese character "匚", and is integrated with the clothes drying rod assembly 10 vertically, which not only provides good overall appearance for the drying assembly 200 after storage, but also greatly saves storage space, so that the entire drying assembly 200 can be lifted and stored around the main machine 301.

[0033] as shown in Figures 4 to 6 , during the conversion process, the first quilt drying rod body 21 and the second quilt drying rod body 21 rotate horizontally relative to the quilt drying rod connecting rod 22, so that the first quilt drying rod body 21, the quilt drying rod connecting rod 22 and the second quilt drying rod body 23 are extended to be collinear, and then the whole is turned downward to the lower part of the clothes drying rod assembly 10.

[0034] as shown in Figure 6 and Figure 7 , to realize quilt drying in a larger range, both the first quilt drying rod body 21 and the second quilt drying rod body 23 are designed as telescopic rod bodies, which specifically comprise an outer rod 24 and an inner rod 25 telescopically sleeved in the outer rod 24. In the unfolded state, a user can pull the inner rod 25 outward from the outer rod 24 to increase the overall length of the quilt drying rod assembly 20, so as to adapt to bedding of different sizes. In this embodiment, after the inner rod 25 is pulled out, it is located between the outer rod 24 and the quilt drying rod connecting rod 22, and the quilt drying rod assembly 20 in the final unfolded state is sequentially the outer rod 24, the inner rod 25, the quilt drying rod connecting rod 22, the inner rod 25 and the outer rod 24 which are connected end to end. A limiting member 26 for preventing the inner rod 25 from accidentally retracting due to gravity during use is arranged between the inner rod 25 and the outer rod 24. The limiting member 26 can be a matching structure of a spring pin and a pin hole, or can be a threaded locking sleeve, and the purpose thereof is to provide reliable unidirectional or bidirectional locking.

[0035] as shown in Figures 4 to 6 and Figure 10As shown, in this embodiment, the quilt drying rod assembly 20 in its unfolded state is connected to the clothes drying rod assembly 10 via a combination of a pull rope 30 and a take-up device 40. Specifically, two take-up devices 40 are fixedly mounted on the clothes drying rod assembly 10, respectively installed in the middle of the front clothes drying rod 11 and the rear clothes drying rod 12. One end of the pull rope 30 is wound and stored in the take-up device 40, and the other end is fixedly connected to the end of the quilt drying rod assembly 20. In the unfolded state, the pull rope 30 is pulled out and naturally tensioned as the quilt drying rod assembly 20 is rotated. At this time, the pull rope 30 and the rod of the quilt drying rod assembly 20 together form a stable triangular support structure. This triangular structure can effectively distribute the load on the quilt drying rod assembly 20, preventing it from sagging and deforming due to the weight of the quilt, and significantly improving the structural strength and stability in the unfolded state.

[0036] Furthermore, such as Figure 10 As shown, in this embodiment, the take-up device 40 has two take-up cavities 41 arranged side by side, each integrating a spiral spring, for winding and storing the pull rope 30 connecting the left quilt drying rod assembly 20a and the right quilt drying rod assembly 20b, respectively. One end of the pull rope 30 is wound and stored in the take-up device 40 by the spiral spring, and the other end is fixedly connected to the front end of the first quilt drying rod body 21 or the rear end of the second quilt drying rod body 23.

[0037] In the retracted state, the first quilt drying rod 21 of the left quilt drying rod assembly 20a and the first quilt drying rod 21 of the right quilt drying rod assembly 20b are retracted above the front clothes drying rod 11, with the front ends of the two first quilt drying rods 21 joined together on the front side of the retracting device 40; the second quilt drying rod 23 of the left quilt drying rod assembly 20a and the second quilt drying rod 23 of the right quilt drying rod assembly 20b are retracted above the rear clothes drying rod 12, with the rear ends of the two second quilt drying rods 23 joined together on the rear side of the retracting device 40. The pull rope is wound and retracted within the retracting device 40, which also acts as a stop and limit for the front ends of the two first quilt drying rods 21 and the rear ends of the two second quilt drying rods 23.

[0038] During the conversion process, the quilt drying rod assembly 20 needs to go through two intermediate unfolded states. For example... Figure 4 The first intermediate unfolded state is shown: the first quilt drying rod 21 and the second quilt drying rod 23 rotate horizontally relative to the quilt drying rod connecting rod 22, causing the first quilt drying rod 21, the quilt drying rod connecting rod 22, and the second quilt drying rod 23 to extend collinearly; at this time, the pull rope 30 is pulled out from the take-up cavity 41 of the take-up device 40. For example... Figure 5 The second intermediate unfolded state is shown: the two quilt drying rod assemblies 20 are flipped downwards as a whole to below the clothes drying rod assembly 10. The pulled-out pull rope 30 and the rod body of the quilt drying rod assembly 20 form a triangular structure. At this time, the quilt drying rod assembly 20 and the clothes drying rod assembly 10 are perpendicular to each other but far apart in the height direction. Figure 6 The final unfolded state shown is as follows: the inner rods 25 of the first quilt drying rod 21 and the second quilt drying rod 23 are pulled outward from the outer rods 24, the overall length of the quilt drying rod assembly 20 reaches its maximum, and the pull rope 30 is fully pulled out and taut. At this time, the height of the quilt drying rod assembly 20 is raised to an appropriate height difference with the clothes drying rod assembly 10 due to the tension of the pull rope 30. The pull rope 30 and the rod of the quilt drying rod assembly 20 together form a stable triangular support structure.

[0039] When storing, the operation sequence is the reverse of the unfolding sequence. The spiral spring inside the retractor 40 will automatically retract the pull rope 30, maintaining a clean and neat appearance.

[0040] In other embodiments, a foldable rigid support rod can be provided between the clothesline assembly 10 and the quilt drying rod assembly 20, or a spring clip, locking hinge, or other structure can be used to maintain the quilt drying rod assembly 20 in its unfolded state. The advantage of the pull rope 30 and the winding device 40 scheme of this embodiment is that by using the tensioned pull rope 30 and the quilt drying rod assembly 20 to form a triangular support structure, the bending moment generated by the load on the quilt drying rod assembly 20 is converted into the axial tension of the pull rope 30. This achieves effective structural reinforcement of the quilt drying rod assembly 20 with a simple, lightweight, and flexible component, significantly improving its load-bearing stiffness and anti-sagging ability. At the same time, the winding device 40 can automatically wind up the pull rope 30 when storing the quilt drying rod assembly 20, keeping the appearance neat.

[0041] Furthermore, this embodiment adopts a cross-shaped structure where the quilt drying pole assembly and the clothes drying pole assembly are perpendicular to each other. From the perspective of the pull rope and reel-in device, this cross-shaped structure allows the pull rope to be symmetrically led out from both ends of the front and rear clothes drying poles. The pull ropes on both sides are of equal length and have the same tension. The resulting triangular support structure is more regular and symmetrical, avoiding the problem of uneven force and structural instability caused by the different lengths of the pull ropes when the poles are crossed at an angle. At the same time, the symmetrical layout also makes it easier to unify the installation position of the reel-in device, which is convenient for manufacturing and assembly.

[0042] like Figure 4 , Figure 5 , Figures 7 to 9 As shown, to achieve precise positioning and stable storage in the folded state, the upper surface of the clothesline connecting plate 13 is specially provided with a protruding structure 14. Correspondingly, the lower surface of the quilt drying rod connecting rod 22 is provided with a concave cavity structure 27 that cooperates with the protruding structure 14. In the folded state, the quilt drying rod connecting rod 22 moves downward, and the protruding structure 14 precisely enters the concave cavity structure 27, thereby positioning and holding the quilt drying rod assembly 20 above the clothesline assembly 10, effectively preventing it from shaking or shifting during lifting and lowering, and improving the reliability and operability of the product.

[0043] Furthermore, such as Figures 7 to 9As shown, to improve the user experience and make the unfolding action smoother, a pushing component 50 is provided between the rear end of the first quilt drying rod 21 and the front end of the quilt drying rod connecting rod 22, and between the front end of the second quilt drying rod 23 and the rear end of the quilt drying rod connecting rod 22. The pushing component 50 can realize the "automatic lifting" function during unfolding, and it includes a movable part 51 and an elastic pushing part 52.

[0044] Specifically, the elastic pusher 52 rotates synchronously with the first drying rod 21 or the second drying rod 23. The movable part 51 is slidably disposed in the internal cavity of the drying rod connecting rod 22. The outer end of the protruding structure 14 is provided with a guide slope 15, which works in conjunction with the movable part 51. When the user rotates the first drying rod 21 or the second drying rod 23, causing it to rotate collinear with the drying rod connecting rod 22, the elastic pusher 52 rotates accordingly to be collinear with the movable part 51. The elastic pusher 52 pushes the movable part 51 to engage with the protruding structure 14, thereby lifting and separating the drying rod connecting rod 22 from the clothesline connecting plate 13.

[0045] like Figure 8 and Figure 9 As shown, during the process of the elastic pusher 52 rotating synchronously with the first quilt drying rod 21 or the second quilt drying rod 23 to collinearity, the inner end of the elastic pusher 52 abuts against the outer end of the movable part 51, and the elastic pusher 52 forms contact with the inner wall of the first quilt drying rod 21 or the second quilt drying rod 23. Its elastic force is released and pushes the movable part 51, causing it to move towards the protruding structure 14. The inner end of the movable part 51 touches the guide slope 15 of the protruding structure 14. Using the slope principle, the horizontal thrust of the movable part 51 is converted into the upward lifting force of the quilt drying rod connecting rod 22, thereby automatically and gently lifting and separating the quilt drying rod connecting rod 22 from the clothes drying rod connecting plate 13, providing the necessary operating gap for the subsequent downward flipping action.

[0046] This integrated design seamlessly connects the "rotate to position" and "lift to unlock" actions, eliminating the need for additional flicking or pressing by the user and providing a clear and definite tactile feedback. The push component 50 combines the traditional two-step "unlock then flip" operation into a single, continuous action of "rotate to position and automatically unlock," significantly simplifying the user's operation, especially beneficial for users with less strength or limited mobility. The spring component 52 utilizes its own elastic force to drive the moving component 51; its ingenious structure requires no external power source and offers immediate and reliable response.

[0047] The following describes in detail the unfolding method of the staggered cross-type quilt drying rack unfolding structure provided by the present invention, based on the above structural features. This method fully embodies the collaborative working logic between the various structural components of the present invention, and specifically includes the following steps: Step S1: Rotate the quilt drying rod assembly 20 that is gathered above the clothes drying rod assembly 10, so that the segments of the quilt drying rod assembly 20 extend from the bent state to the collinear state.

[0048] like Figure 3 and Figure 4 As shown, specifically, the left and right quilt drying rod assemblies 20a and 20b, which are retracted above the clothesline assembly 10, are rotated horizontally to the left and right. During this process, the first quilt drying rod 21, the connecting rod 22, and the second quilt drying rod 23, which were originally bent, gradually extend. When the first quilt drying rod 21, the connecting rod 22, and the second quilt drying rod 23 are collinear, the push assembly 50 lifts and separates the connecting rod 22 from the clothesline connecting plate 13. At the same time, the pull rope 30 is gradually pulled out from the first device 40 as the first quilt drying rod 21 and the second quilt drying rod 23 rotate.

[0049] Step S2: Flip the quilt drying rod assembly 20, which is extended in a collinear state, downwards so that it moves below the clothes drying rod assembly 10 and the extension direction of the quilt drying rod assembly 20 intersects with the extension direction of the clothes drying rod assembly 10.

[0050] like Figure 4 and Figure 5 As shown, specifically, the left and right quilt drying rod assemblies 20a and 20b, which have been extended into a collinear state and lifted, are flipped inward and downward around their hinge axes, moving them from above to below the clothes drying rod assembly 10. During this flipping process, the pull rope 30, with one end connected to the end of the quilt drying rod assembly 20 and the other end wound in the take-up device 40, is gradually pulled out until it reaches its maximum length due to the gravity of the quilt drying rod assembly 20, and the spiral spring in the take-up device 40 stores energy. After flipping to the correct position, the left and right quilt drying rod assemblies 20a and 20b are parallel and close together, and the extension directions of both are perpendicular to the first direction defined by the front clothes drying rod 11 and the rear clothes drying rod 12. At this time, the quilt drying rod assembly 20 and the clothes drying rod assembly 10 form a staggered and intersecting layout.

[0051] Step S3: Stretch the telescopic part of the quilt drying rod assembly 20 outward to the required length and lock it with the limiting member 26 to complete the unfolded state.

[0052] like Figure 5 and Figure 6 , and then combine Figure 1As shown, specifically, the inner rods 25 of the first and second drying rod bodies 21 and 23 in the left and right drying rod assemblies 20a and 20b are stretched outwards, extending from the outer rod 24 to increase the length of the drying rod assembly 20. When the inner rod 25 is fully extended, the limiting member 26 between the inner rod 25 and the outer rod 24 automatically locks, preventing the inner rod 25 from retracting. At this time, since the pull rope 30 has been fully stretched in step S2, and the length of the drying rod assembly 20 has increased, the angle between the pull rope 30 and the drying rod assembly 20 decreases, raising the height of the drying rod assembly 20 to an appropriate height difference with the clothes drying rod assembly 10. The pull rope 30 and the rod body of the drying rod assembly 20 form a stable triangular support structure, completing the entire unfolding action. At this point, the user can simultaneously dry clothes and quilts without interference in the staggered drying space.

[0053] In summary, the staggered cross-type quilt drying rack unfolding structure, unfolding method, and clothes drying machine provided by this invention can achieve at least the following three technical effects: First, the staggered, intersecting layout fundamentally solves the problem of clothing and bedding interference. This invention creates a staggered, intersecting drying space by setting the extension direction of the quilt-drying rod assembly to intersect with the extension direction of the clothes-drying rod assembly in its unfolded state. This fundamentally solves the problem in existing technologies where clothes and quilts overlap and block each other on the longitudinal projection plane due to the parallel arrangement of quilt-drying and clothes-drying rods, truly achieving spatial non-interference when clothes and quilts are dried together.

[0054] Secondly, the appropriate height difference design balances a compact structure with the ability to dry long garments. The staggered, cross-layered layout of this invention eliminates the need to horizontally expand the overall width of the machine or excessively lengthen the hanging distance to avoid interference between the quilt drying rod and the clothes drying rod. This allows for a suitable height difference between the two, ensuring a compact structure and minimal increase in size while providing ample drying height below the clothes drying rod. This allows for the normal drying of long garments such as long skirts and trench coats, overcoming the shortcomings of existing technologies that are bulky or compress the upper drying space.

[0055] Third, the cross-structure breaks the fixed space allocation pattern. This invention, through the cross-layout of the quilt-drying rod assembly and the clothes-drying rod assembly, breaks the traditional fixed space allocation pattern of drying quilts on one side and clothes on the other. In the unfolded state, users can freely hang clothes and quilts at any location within the entire drying area, achieving flexible allocation and free combination of drying space, significantly improving space utilization and user convenience.
