Description

Technical Field

[0001] This utility model relates to the field of drying device technology, and in particular to a drying rack and a clothes drying machine. Background Technology

[0002] In everyday drying scenarios, drying racks typically feature retractable movable components on their main body. These components can be lowered to open or retract into the main body to suit different drying conditions. However, in related technologies, these movable components that can move relative to the main body are usually adjusted by hand-pushing or pulling to meet storage or usage needs. This method is inconvenient and time-consuming. Summary of the Invention

[0003] The purpose of this utility model embodiment is to provide a drying rack and clothes drying machine that can not only realize the electric extension and retraction of the movable components on the main body of the drying rack, but also make it more convenient for users to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A drying rack, comprising: The main body of the drying rack includes the base; A driving component is disposed on the base; Two longitudinal transmission components are connected to the driving component, and the two longitudinal transmission components are arranged on the same side of the driving component and are staggered and parallel. The two movable components are respectively connected to the two longitudinal transmission components; The driving component drives the two longitudinal transmission members to move, thereby causing the two movable components to move away from or towards each other.

[0005] Optionally, the drying rack body includes two spaced-apart bases, each base being provided with the driving component, two longitudinal transmission components, and two movable components; the drying rack includes two movable drying rods, the two ends of each movable drying rod being connected to two movable components on the two bases with the same extension and retraction direction.

[0006] Optionally, the movable component includes a slider and a movable rod. The slider is pulsatorically connected to the longitudinal transmission component, and the movable rod is rotatably connected to the slider. The driving component drives the two sliders to move closer or further apart from each other through the two longitudinal transmission components, so that the two movable rods retract or extend from the base. When the movable rod extends to the part rotatably connected to the slider and disengages from the base support, the movable rod can flip downward relative to the slider and the base. Alternatively, the movable component may include multiple hinged blocks that are hinged sequentially, with the first hinged block being connected to the longitudinal transmission component and the last hinged block being connected to the movable drying rod.

[0007] Optionally, the driving component includes a driving motor, which is a dual-head motor. Motor shafts are respectively provided at opposite ends of the driving motor, and the two motor shafts are respectively connected to the two longitudinal transmission components. Alternatively, the driving component includes two driving motors, both of which are single-head motors, each of which has a motor shaft, and the motor shaft of each driving motor is connected to a longitudinal transmission component. Alternatively, the driving component is a single-head motor, which has a motor shaft that is connected to the two longitudinal transmission components respectively.

[0008] Optionally, the motor shaft is parallel to the longitudinal transmission member.

[0009] Optionally, the longitudinal transmission component is a screw, which is rotatably connected to the base, and the movable component is sleeved on the screw and threadedly connected to the screw; The driving component drives the screw to rotate, thereby driving the movable component to reciprocate along the screw.

[0010] Optionally, the driving component is a dual-head motor, and the two ends of the dual-head motor have a first motor shaft and a second motor shaft, respectively; The two longitudinal transmission components are a first screw and a second screw, respectively. The first motor shaft is connected to the first screw, and the second motor shaft is connected to the second screw through a steering transmission component, so that when the first motor shaft and the second motor shaft rotate in the same direction, the first screw and the second screw are driven to rotate in opposite directions.

[0011] Optionally, it also includes a first input pulley, a first synchronous belt, a first output pulley, a second input pulley, a second synchronous belt, and a second output pulley; the steering transmission component is a steering transmission pulley; The first motor shaft is driven to the first input wheel, the first input wheel is driven to the first output wheel via the first synchronous belt, and the first output wheel is driven to the first screw. The second motor shaft is driven to the second input wheel, the second input wheel meshes with the steering drive wheel, the steering drive wheel is driven to the second output wheel via the second synchronous belt, and the second output wheel is driven to the second screw; or, the second motor shaft is driven to the second input wheel, the second input wheel is driven to the steering drive wheel via the second synchronous belt, the steering drive wheel meshes with the second output wheel, and the second output wheel is driven to the second screw.

[0012] Optionally, the base has an internal mounting cavity, and the driving component and the longitudinal transmission component are both disposed in the mounting cavity; Both of the longitudinal transmission components are screws rotatably connected to the base; the movable component has a rod hole inside, and a nut is installed on the movable component, which is threadedly connected to the screw; when both movable components are retracted into the base, each screw passes through the corresponding rod hole, so that each movable component is sleeved on the outside of the corresponding screw, and the two movable components are staggered and parallel on the same side of the driving component.

[0013] A clothes drying rack includes a main unit and a drying rack; the main body of the drying rack is connected to the main unit via a connecting component.

[0014] The beneficial effects of this utility model are as follows: the power is transmitted to the parallel and staggered longitudinal transmission components through the driving component, and then the two longitudinal transmission components drive the corresponding movable components respectively, so that the two movable components can move closer or further away from each other, thereby making the two movable components extend or retract from the base synchronously. The movable component can extend horizontally from the base, or it can extend from the base and at least partially flip downward relative to the base.

[0015] When the end of the movable component is connected to a drying part (such as a movable drying rod), or when the movable component itself is used as a drying part, the drying part can be unfolded when needed and retracted when idle by driving the power output of the component. This avoids the jamming problem and cumbersome operation that are easy to occur with manual operation, making the use of the drying function smoother.

[0016] Two longitudinal transmission components are positioned on the same side of the drive unit, and they are staggered and parallel. This layout effectively avoids space constraints for the drive unit. Given the limited length of the base, the internal space of the base can be fully utilized to extend the transmission stroke of the longitudinal transmission components, enabling them to drive the movable parts to achieve a wider range of motion. Ultimately, this achieves the effect of maintaining a compact shape while allowing the movable parts to have a greater range of adjustment. Attached Figure Description

[0020] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" 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 utility model based on the specific circumstances.

[0022] In this invention, unless otherwise explicitly 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 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 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.

[0023] In everyday home drying scenarios, drying racks typically provide basic drying functions. Examples include clothes drying racks, wall-mounted drying racks, and floor-standing drying racks. To meet different drying needs, some drying racks have movable components in their main body. These movable components themselves serve as drying rods, or the ends of the movable components are connected to drying rods. Users manually push or pull the movable components to open them when needed and retract them when not in use.

[0024] However, this manual operation method is not only relatively troublesome, but also time-consuming and detrimental to drying efficiency. When operating the moving parts, uneven force applied by the user can easily cause the moving parts to move unevenly on the main body of the drying rack, resulting in slight jamming and affecting the user experience.

[0025] In order to solve the problems in the related technology, this application provides a drying rack and a clothes drying machine.

[0026] The advantages of the drying rack and clothes dryer in this application are: Firstly, the drive mechanism enables the extension and retraction of movable components, eliminating the need for manual operation by the user, thus saving time and improving drying efficiency.

[0027] Secondly, the electric extension and retraction of the moving parts helps to distribute the force evenly on the moving parts, thereby improving the stability and smoothness of the reciprocating motion of the moving parts.

[0028] Thirdly, the two longitudinal transmission components are arranged on the same side of the drive component, and the two longitudinal transmission components are arranged in parallel and staggered order. This helps to increase the greater stroke of the moving components within the limited base space, taking into account both the compact design of the entire drying rack and the need for a greater range of adjustment of the moving components, thus meeting the needs of more drying scenarios.

[0029] The intelligent telescopic drying rack of this application can be used in ceiling-mounted electric clothes drying racks, as well as as wall-mounted drying racks installed on vertical walls, or as floor-standing drying racks directly supported on the ground.

[0030] The clothes drying rack of this application can combine the compact structure and ease of use of a drying rack.

[0031] The following reference Figures 1 to 14 This application provides a detailed description of the drying rack and clothes drying machine. To facilitate understanding of the fit between the components, the accompanying drawings illustrate the width direction (x-direction) and length direction (y-direction).

[0032] The drying rack includes a main body, which in turn includes a base 13. The base 13 is equipped with a telescopic assembly, which includes a drive component 21, two longitudinal transmission components 23, and two movable components 22. In one embodiment, the drying rack main body includes two bases 13, each base 13 having a set of telescopic assemblies. In other embodiments, the drying rack main body may include only one base 13, or more than two bases 13. The following description continues with an example of a drying rack main body including two bases 13.

[0033] Reference Figures 1 to 3 The main body of the drying rack provides basic drying functions. It includes two bases 13 and two clotheslines 111, with each end of the clothesline 111 connected to one of the two bases 13. For example, the two bases 13 are spaced apart in the front-to-back direction, and the two clotheslines 111 are spaced apart in the left-to-right direction, with their front and rear ends connected to the front and rear bases 13 respectively. In typical drying scenarios, users can hang clothes on the clotheslines 111 or clip clothes onto the clotheslines 111 or the clips on the crossbar between the two clotheslines 111.

[0034] Reference Figures 7 to 9 Each base 13 is provided with a set of telescopic components. The telescopic components include a drive component 21, two longitudinal transmission members 23, and two movable members 22. The drive component 21 is disposed on the base 13, and both longitudinal transmission members 23 are driveably connected to the drive component 21, enabling the drive component 21 to drive the two longitudinal transmission members 23 to move. The two movable members 22 correspond to the two longitudinal transmission members 23 respectively, and each movable member 22 is driveably connected to one longitudinal transmission member 23.

[0035] Continue to refer to Figures 7 to 10 The driving component 21 drives the two longitudinal transmission members 23 to move, thereby causing the two movable members 22 to move away from or towards each other. For example, the driving component 21 has two working states. In the first working state, by driving the two longitudinal transmission members 23 to move, the two movable members 22 are driven to move towards each other, causing the two movable members 22 to move simultaneously into the base 13. In the second working state, by driving the two longitudinal transmission members 23 to move, the two movable members 22 are driven to move away from each other, causing the two movable members 22 to move towards both ends of the base 13, with the two movable members 22 extending out of the base 13 from both ends.

[0036] Continue to refer to Figure 7 , Figure 10Two longitudinal transmission members 23, mounted on the same base 13, are disposed on the same side of the drive component 21 and are staggered and parallel. Exemplarily, the two bases 13 are spaced apart in the front-to-back direction and extend in the left-to-right direction. The two longitudinal transmission members 23 also extend in the left-to-right direction, and are jointly arranged on the upper side of the base 13, with one in front of the other spaced apart. In other embodiments, the two longitudinal transmission members 23 may also be jointly arranged on the lower, front, or rear side of the base 13.

[0037] In one embodiment, Figures 1 to 3 In the middle, the end of the movable component 22 is connected to the movable drying rod 30. The movable component 22 is driven to reciprocate by the driving component 21, which in turn drives the movable drying rod 30 to reciprocate, so that the movable drying rod 30 reciprocates between the folded position and the used position.

[0038] The drying rack includes two movable drying rods 30. Both ends of each movable drying rod 30 are connected to two movable components 22 on two bases 13, each with the same extension / retraction direction. For example, one of the two movable components 22 on each base 13 can move to the left to extend beyond the base 13, and the other can move to the right to extend beyond the base 13. Correspondingly, the front and rear ends of the left movable drying rod 30 are connected to the movable components 22 on the front and rear bases 13 that can move to the left to extend beyond the base 13, and the front and rear ends of the right movable drying rod 30 are connected to the movable components 22 on the front and rear bases 13 that can move to the right to extend beyond the base 13.

[0039] In other embodiments, the movable member 22 itself is used as a drying rod 11. When the movable member 22 is driven to extend out of the base 13 by the driving member 21, it is convenient to hang clothes hangers on the movable member 22 or use the clips on the movable member 22 to hold clothes.

[0040] Taking the example of a movable drying rod 30 connected to the end of the movable component 22, in an actual drying scenario, when a user needs to dry large items (such as bed sheets or duvet covers), the drive component 21 can be activated to drive the two longitudinal transmission components 23 to move, thereby causing the two movable components 22 to move away from each other. At this time, the movable drying rod 30 connected to the end of the movable component 22 will extend synchronously from both ends of the base 13 until it reaches the preset usage position. The user can then lay or hang the large items on the movable drying rod 30 without manually pulling the drying rod 11. After drying is completed, the drive component 21 can be activated again to bring the two movable components 22 closer together. The movable drying rod 30 will then retract synchronously into the base 13, returning to the folded position, avoiding occupying extra space and keeping the drying rack compact, thus reducing the overall space occupied by the drying rack.

[0041] In the case of the drying rack of this application, where the movable component 22 is connected to the movable drying rod 30, or where the movable component 22 itself is used as the drying rod 11, there is no need to manually open the movable component 22. Users can control the drive component 21 by inputting control commands through mobile phone software, remote control, or by sensing signals from sensors. The drive component 21 then cooperates with the longitudinal transmission component 23 to electrically push out or retract the movable component 22. The operation is convenient and quick, which can reduce the cumbersome operation, save users' time, and improve drying efficiency.

[0042] The drying rack of this application also solves the problem of uneven movement caused by manually adjusting the movable component 22. When manually pushing and pulling the movable component 22, the magnitude and direction of the force applied by the user are prone to deviation, which can easily cause the movable component 22 to rub against the inner wall of the base 13, resulting in jamming and abnormal noise. However, this application provides stable and uniform power through the drive component 21, and together with the transmission between the longitudinal transmission component 23 and the movable component 22, it can ensure that the extension and retraction of the movable component 22 is smooth and without jamming, while avoiding structural wear caused by uneven force application.

[0043] Furthermore, when the movable drying rod 30 is configured, and both ends of the movable drying rod 30 are respectively connected to two movable components 22 on the same side of the two bases 13, the drive components 21 of the front and rear bases 13 can be started synchronously by controlling them. The two drive components 21 drive the longitudinal transmission components 23 in their respective bases 13 to move, thereby driving the two movable components 22 to extend outward or retract inward synchronously. Through dual-drive synchronous control, the movement speed and stroke of the front and rear ends of the movable drying rod 30 are consistent, avoiding the tilting of the movable drying rod 30 due to the difference in the extension speed of the front and rear movable components 22; while the drying rod 11 remains in a horizontal state, so that the force is evenly distributed on the movable components 22 at both ends, effectively preventing transmission jamming caused by excessive force on one side, and improving the stability and smoothness of the movable drying rod 30 during opening and closing.

[0044] Furthermore, the drying rack of this application also resolves the contradiction between space occupation and drying flexibility. The inventors discovered that when the base 13 is equipped with a drive component 21 and a longitudinal transmission component 23, if the drive component 21 is used to control the movable component 22 to extend beyond the base 13 to increase the extension and retraction stroke of the movable component 22, a longer longitudinal transmission component 23 is usually required to push the movable component 22 to move a longer distance; however, increasing the length of the longitudinal transmission component 23 requires a corresponding increase in the length of the base 13, which leads to a larger overall size of the drying rack, making it difficult to meet the needs of modern families for miniaturized designs. This application, by setting the two longitudinal transmission components 23 on the same side of the drive component 21 and adopting a parallel and staggered layout, can arrange longer longitudinal transmission components 23 without increasing the overall length of the base 13, thereby maximizing the extension and retraction stroke of the movable component 22, expanding the range of motion of the movable component 22 itself, and expanding the range of motion of the movable drying rod 30 to meet more drying needs; at the same time, when retracted, the movable component 22 can be completely stored in the base 13, taking into account both the space requirements of small apartment balconies and the drying needs of large families.

[0045] Taking the example of two longitudinal transmission components 23 arranged in the upper space inside the base 13 and the driving component 21 arranged in the lower space inside the base 13, the two longitudinal transmission components 23 can avoid the lower space where the driving component 21 is already located. This utilizes the limited installation space inside the base 13 to achieve the following two effects: First, a longer longitudinal transmission component 23 can be arranged, allowing for a better extension and retraction distance of the movable component 22. Second, when the movable component 22 needs to be retracted into the base 13, the movable component 22 is approximately located at the same height as the longitudinal transmission components 23, which also facilitates the arrangement of a longer movable component 22 without obstruction by the driving component 21. Furthermore, the staggered arrangement of the two longitudinal transmission components 23 in the front-rear direction avoids mutual interference between their movements.

[0046] Continue to refer to Figures 1 to 3 The clothes drying rack includes a main unit (the main unit is omitted in the figure), a drying rack, and a connecting component 60. The main body of the drying rack is connected to the main unit through the connecting component 60.

[0047] Optionally, there are two sets of connecting components 60, spaced apart along the length of the drying rack. The drying rack is connected to the lower side of the main unit via the two sets of connecting components 60. Each set of connecting components 60 includes a connecting rope, which can be made of a high-strength material such as steel wire rope. The main unit contains a winding and unwinding assembly, with both ends of the connecting rope connected to the winding and unwinding assembly and the main body of the drying rack, respectively. By winding and unwinding the connecting rope through the winding and unwinding assembly, the main body of the drying rack can be raised or lowered, thereby raising or lowering the entire intelligent telescopic drying rack. Optionally, each set of connecting components 60 includes a folding rod assembly, which can be a scissor-type assembly. The folding rod assembly extends when the drying rack rises and retracts when the drying rack lowers. The folding rod assembly improves the stability of the drying rack during lifting and lowering, providing better wind resistance and stability.

[0048] In one embodiment, reference is made to Figure 3 The drying rack includes two movable drying rods 30, and the two ends of each movable drying rod 30 are respectively connected to two movable components 22 on the two bases 13 with the same extension and retraction direction.

[0049] For example, the drying rack has bases 13 on both the front and rear sides, and each base 13 has two movable members 22. Of the two movable members 22 on each base 13, one is a left-side extending member that can move to the left to extend out of the base 13; the other is a right-side extending member that can move to the right to extend out of the base 13. Two movable drying rods 30 are arranged one on the left and one on the right. The two ends of the left movable drying rod 30 are connected to the left-side extending members on the front and rear bases 13, respectively, and the two ends of the right movable drying rod 30 are connected to the right-side extending members on the front and rear bases 13, respectively.

[0050] Optionally, the movable drying rod 30 includes a quilt rod 31. By having two movable components 22 on the same side of the two bases 13 extend from the two bases 13 simultaneously, the quilt rod 31 can be unfolded, allowing the quilt rod 31 to be a certain distance away from the main body of the drying rack, making it convenient for hanging operations. At this time, users can hang large fabrics such as bed sheets and quilt covers on the quilt rod 31 for drying.

[0051] Optionally, the movable drying rod 30 has at least two positions, namely a retracted position (e.g., ... Figure 2 As shown), scroll down (as shown) Figure 1 As shown). Figure 2 As shown, when the two movable components 22 retract to the base 13, the movable drying rod 30 is pulled back to a position close to the base 13 and able to be supported by the base 13. At this time, the overall structure is compact and saves space. Figure 1 As illustrated, when the two movable components 22 extend from the base 13 and at least partially flip downward relative to the base 13, the movable components 22 drive the movable drying rod 30 to flip downward to below the main body of the drying rack, facilitating the use of the movable drying rod 30 and making full use of the height space. Figure 3In some embodiments, when the two movable components 22 extend out of the base 13 but are restricted by the base 13 from flipping downwards, the movable drying rod 30 is located in the outward position on the horizontal outer side of the drying rack body. At this time, the movable drying rod 30 can also be used to dry quilts, etc.

[0052] In this embodiment, the movable drying rods 30 are connected to the two movable components 22 on the two bases 13 that can extend to the same side. The drive component 21 and the longitudinal transmission component 23 can be directly linked. The user only needs to trigger the electric control through remote control, APP, etc., to make the two movable quilt rods 31 extend (unfold to the drying position) or retract (fold to a compact state) from both ends of the base 13 synchronously. There is no need for manual contact throughout the process, which reduces the operation threshold and improves the drying efficiency. The two ends of the left and right movable quilt rods 31 are respectively connected to the movable components 22 on the same side of the front and rear bases 13. With the uniform power output by the drive component 21 through the longitudinal transmission component 23, it can be ensured that the two ends of the quilt rods 31 are subjected to consistent force and move synchronously. For example, when unfolding, the left and right quilt rods 31 always remain horizontal and will not tilt due to one side extending too fast. When folding, they can also smoothly approach the base 13, which completely solves the jamming problem of manual adjustment, while reducing mechanical wear and extending the service life of the quilt rods 31.

[0053] Furthermore, from a spatial adaptability perspective, increasing the unfolding distance of the quilt rod 31 to accommodate a larger operating space would typically involve increasing the length of the base 13. However, this would result in an excessively large lateral dimension of the entire drying rack, making it unsuitable for small balconies. In this embodiment, based on the structural design of the two longitudinal transmission components 23 staggered and parallel within the base 13, the movable component 22 can be driven to extend the quilt rod 31 through a longer transmission stroke without increasing the overall length of the base 13. For example, during daily storage, the quilt rod 31 can be kept close to the base 13 without occupying extra space; during drying, it can be unfolded to a position away from the base 13. For instance, the quilt rod 31 can be unfolded and folded down below the base 13, and it can be adjusted to different heights to meet the hanging and drying needs of different quilts, making it more flexible.

[0054] In other embodiments, the movable drying rod 30 may not simply be used as the hanging rod 31. The movable drying rod 30 may be provided with hanging holes or grooves for hanging clothes hangers, or with clips for clamping clothes. When the movable member 22 extends out of the base 13 to unfold the movable drying rod 30, the user can use the clothes drying rod 111 to hang or clamp clothes, or use the movable drying rod 30 to hang or clamp clothes. The drying area is large, which can meet the large drying needs of families with many people.

[0055] In other embodiments, the movable drying rod 30 may not be provided. Instead, clothespins, hanging holes, etc., may be provided on the movable component 22. The movable component 22 can be pushed out of the base 13 by electric control, so that users can conveniently hang small items of clothing to dry in the front and back areas of the drying rack by clamping them with clips or hanging them on small hangers.

[0056] In one embodiment, reference is made to Figure 4 In the case where the drying rack includes the movable drying rod 30, in order to make the use of the drying rack more flexible, the main body of the drying rack is configured to be able to extend and retract longitudinally, and correspondingly the movable drying rod 30 is also configured to be able to extend and retract longitudinally.

[0057] The clothes drying rod 11 includes a clothes drying rod 111 and two telescopic clothes drying rods 112 retractably mounted on the clothes drying rod 111. The two telescopic clothes drying rods 112 extend from both ends of the clothes drying rod 111. Each clothes drying rod 11 has two telescopic clothes drying rods 112 connected to two bases 13. The movable clothes drying rod 30 includes a quilt rod 31 and quilt drying telescopic rods 32. Each movable clothes drying rod 30 has two quilt drying telescopic rods 32 connected to two bases 13. The main body of the drying rack includes a bracket 12, with two brackets 12 connected between the two clothes drying rods 111.

[0058] In other words, the two brackets 12 and the two clothes drying rods 111 form the main frame 101, the two clothes drying telescopic rods 112 located on the front side and the front brackets 12 form the front side frame 102, and the two clothes drying telescopic rods 112 located on the rear side and the rear brackets 12 form the rear side frame 102. Each movable drying rod 30 includes a quilt rod 31 and a front quilt drying telescopic rod 32 and a rear quilt drying telescopic rod 32 that can extend from the front and rear ends of the quilt rod 31, respectively.

[0059] In scenarios involving small daily laundry loads on small balconies, or when a clothes drying rack is not needed, both the drying rod 11 and the quilt rod 31 can be adjusted to a retractable state to fit the limited balcony space. For example, when drying a small amount of clothing, all the drying rods 11 and quilt rods 31 can be adjusted to a vertically retractable state, with the two telescopic rods 112 on each drying rod 111 retracting to the drying rod 111, and the two telescopic rods 32 on each quilt rod 31 retracting to the quilt rod 31, keeping the overall vertical dimension of the drying rack relatively small.

[0060] When it is necessary to increase the drying capacity, the clothes drying telescopic rods 112 on the front, back, or front and back sides of the drying rod 11 can be extended outwards. Correspondingly, the quilt drying telescopic rods 32 on the front, back, or front and back sides of the quilt rod 31 can also be extended outwards at the same time, thereby increasing the longitudinal dimension of the entire drying rack and expanding the drying space.

[0061] In other embodiments, both the drying rod 11 and the blanket rod 31 may be fixed and non-extendable structures.

[0062] The active component 22 can be configured in at least two of the following ways.

[0063] One of the configuration methods for active component 22: Refer to 5. Figures 7 to 10 The movable component 22 includes a sliding member 221 and a movable rod 222. One end of the sliding member 221 is connected to the longitudinal transmission member 23, and the other end of the movable rod 222 is rotatably connected to the sliding member 221. For example, the movable rod 222 is rotatably connected to the sliding member 221 via a rotating shaft 223. The driving component 21 can drive the two sliding members 221 to slide along the length of the base 13 via the two longitudinal transmission members 23, so that the two sliding members 221 move closer to each other or further away from each other, so that the two movable rods 222 retract or extend from the base 13, thereby causing the movable drying rod 30 connected to the end of the movable rod 222 away from the base 13 to retract and extend.

[0064] When each movable rod 222 extends out of the base 13, and the part of the movable rod 222 that is rotatably connected to the sliding member 221 is disengaged from the support of the base 13, the movable rod 222 can flip downward relative to the sliding member 221 and the base 13.

[0065] For example, under normal conditions, the movable drying rod 30 is not needed. In this case, the movable drying rod 30 should be kept as close as possible to the main body of the drying rack to make the overall shape of the drying rack more compact. This not only saves space but also prevents the movable drying rod 30 from obstructing the normal use of the clothes drying rod 111. When the movable drying rod 30 needs to be used, the drive component 21 on the base 13 transmits power to the sliding component 221 through the longitudinal transmission component 23. This causes the sliding component 221 to push the movable rod 222 to slide towards the end of the base 13. The movable rod 222 continues to extend outward from the base 13, so that the movable drying rod 30 continuously moves away from the end of the base 13, thus enabling the movable drying rod 30 to be deployed.

[0066] In this configuration, the movement of the movable rod 222 is divided into two stages, and the position of the movable drying rod 30 is associated with the two movement stages of the movable rod 222.

[0067] When the movable rod 222 is in the first movement stage (horizontal extension stage): when the driving component 21 pushes the sliding component 221 to move outward of the base 13 through the longitudinal transmission component 23, the rotational connection between the sliding component 221 and the movable rod 222 is always supported by the structure of the base 13 (such as the limiting protrusion on the inner wall of the base 13, the supporting plane, etc.). Part of the structure of the base 13 will block the rotational path of the movable rod 222 relative to the sliding component 221 (for example, limiting it from above or below). At this time, the movable rod 222 cannot be rotated, and can only move horizontally along the length direction of the base 13 with the sliding component 221. The movable drying rod 30 is simultaneously located on the horizontal outer side of the drying rack body (such as the left movable drying rod 30 being located on the left side of the drying rack body and the right movable drying rod 30 being located on the right side of the drying rack body), maintaining a state that is approximately parallel to the base 13.

[0068] In the second movement stage (downward flipping stage) of the movable rod 222: as the sliding member 221 continues to move outward, when the rotating connection between the sliding member 221 and the movable rod 222 is completely detached from the support of the base 13 (no longer limited by the structure of the base 13), under the combined action of the weight of the movable rod 222 itself and the weight of the movable drying rod 30, the movable rod 222 will flip downward relative to the sliding member 221 and the base 13 around the rotating connection until the movable rod 222 is perpendicular or approximately perpendicular to the base 13. At this time, the movable drying rod 30 will change from a horizontal outer state to being suspended below the main body of the drying rack, forming a hanging drying space that facilitates the drying of items (such as quilts).

[0069] Optionally, when the movable drying rod 30 is retracted into the base 13 and in the retracted state, the movable drying rod 30 is close to the drying rack body, and the drying rack body can support the movable drying rod 30. For example, when the movable drying rod 30 is in the retracted state, the sliding member 221 and the movable rod 222 in the movable component 22 are retracted into the base 13, the movable drying rod 30 is located above the two bases 13, and both ends are supported by the bases 13 respectively, so the movable drying rod 30 will not fall off.

[0070] In one configuration of the movable component 22, the power of the drive component 21 can be directly transmitted to the movable rod 222 via the sliding member 221, and then to the movable drying rod 30, reducing power loss and jamming during extension and retraction, making the extension and retraction of the movable component 22 smoother. During the downward flipping phase of the movable rod 222, the single-segment movable rod 222 structure hangs naturally under gravity, reducing the risk of jamming. With the movable drying rod 30 suspended below the main body of the drying rack, this reduces the swaying of the movable drying rod 30 due to wind, improving drying stability.

[0071] Configuration method 2 for active component 22: like Figure 6 The movable component 22 is a hinge, which includes multiple hinge blocks 224 that are hinged sequentially. The first hinge block 224 is connected to the longitudinal transmission component 23, and the last hinge block 224 is connected to the movable drying rod 30. When the hinge is extended by the longitudinal transmission component 23, each hinge block 224 extends out of the base 13 and flips downward, allowing the movable drying rod 30 to move downward to the bottom of the drying rack body. Conversely, when the longitudinal transmission component 23 retracts the hinge, each hinge block 224 retracts back into the base 13 and flips upward, allowing the movable drying rod 30 to move upward and closer to the drying rack body.

[0072] In other embodiments, the active component 22 may also be configured in other ways.

[0073] The drive unit 21 can be configured in at least three ways.

[0074] One of the configuration methods for drive component 21: Please refer to [link / reference] Figures 7 to 10 The drive component 21 includes a drive motor, which is a dual-head motor. The fixed end of the dual-head motor is connected to and fixed relative to the base 13. The dual-head motor has two output ends, which are two motor shafts located at opposite ends of the fixed end of the drive motor. The two motor shafts are respectively connected to two longitudinal transmission components 23 located on the base 13 and arranged in a staggered manner.

[0075] When drying quilts on a household clothes dryer, the left and right movable drying rods 30 need to extend or retract synchronously for simpler and more reliable control. This configuration uses a single dual-head motor to directly drive the two longitudinal transmission components 23, avoiding the asynchronous problems caused by multiple motors on the same base 13 driving the left and right movable drying rods 30 separately. This results in higher synchronization of the left and right movable rods 222 and reduces quilt offset caused by unilateral lag. At the same time, the single-motor design simplifies the internal structure of the base 13, reducing the space occupied by the motor. This not only reduces the external size of the base 13 but also retains more space for the longitudinal transmission components 23, increasing the travel of the movable components 22 and the movable drying rods 30.

[0076] A second configuration of the drive component 21 (not shown in the figure): The drive component 21 includes two drive motors, both of which are single-head motors. Each drive motor is connected to and relatively fixed to the base 13. Each drive motor has a motor shaft, and each motor shaft is connected to one of the two longitudinal transmission members 23 that are staggered on the base 13.

[0077] When household drying needs differ (e.g., only one side of the movable drying rod 30 needs to be extended to dry a single quilt, or different quilts need to be dried on both sides with independent adjustment of the extension length), the two single-head motor configuration can independently control the two longitudinal transmission components 23 on the same base 13. For example, when drying a thick quilt only on the left side, the left motor can be started alone to drive the corresponding movable rod 222 to extend, while the right side remains folded, avoiding unnecessary energy consumption and space occupation; and if one motor fails, the other can still work normally, ensuring the basic drying function and reducing the risk of the entire quilt drying function failing due to a single motor failure.

[0078] The third configuration of the drive component 21: The drive component 21 includes a drive motor, which is a single-head motor. The fixed end of the single-head motor is connected to and relatively fixed to the base 13. The single-head motor has only one motor shaft, which is connected to two sets of longitudinal transmission components 23. For example, the motor shaft is connected to a primary gear, which is connected to two secondary gears, and the two secondary gears are connected to two longitudinal transmission components 23 on the same base 13.

[0079] In one embodiment, reference is made to Figures 7 to 10 The driving component 21 includes a drive motor with a fixed end and an output end. The fixed end is connected to and fixed relative to the base 13, and the output end is a motor shaft. The extension direction of the motor shaft is consistent with the extension direction of the longitudinal transmission component 23. For example, the length direction of the base 13 is the x-direction, the width direction is the y-direction, and the height direction is the z-direction. Both the motor shaft and the longitudinal transmission component 23 are configured to extend along the x-direction, and the motor shaft is parallel to the longitudinal transmission component 23. In this embodiment, by arranging the motor shaft and the longitudinal transmission component 23 in parallel, the length space of the base 13 is efficiently utilized, avoiding other orientations of the motor shaft from occupying the width or height space of the base 13, thus avoiding an increase in the external dimensions of the base 13 and facilitating the application of the drying rack in limited balcony spaces.

[0080] For example, when the drive component 21 includes a drive motor and the drive motor is a dual-head motor, the two longitudinal transmission members 23 are located above or below the drive motor. The two longitudinal transmission members 23 are staggered one after the other. The dual-head motor has two motor shafts at its left and right ends respectively. The left motor shaft can be connected to the first longitudinal transmission member 23 above through the middle transmission component on the left, and the right motor shaft can be connected to the second longitudinal transmission member 23 above through the middle transmission component on the right.

[0081] In one embodiment, reference is made to Figures 7 to 14 To achieve smooth extension and retraction of the movable component 22 and stable support for the movable drying rack 30 through an indirect transmission structure, the drying rack is configured as follows: the longitudinal transmission component 23 is a screw, the driving component 21 can drive the screw to rotate in both directions, the screw is rotatably connected to the base 13, and the movable component 22 is sleeved on the screw and threadedly connected to the screw. The driving component 21 is a rotary actuator, such as a drive motor, which can drive the screw to rotate in both directions. The threaded engagement between the screw and the movable component 22 converts the rotational power into linear power to drive the movable component 22 to reciprocate along the screw, thereby extending and retracting the movable component 22.

[0082] For example, the movable component 22 is configured in one of the configuration methods described in the above embodiments. The motor shaft of the drive motor is coaxially connected to the screw. A nut 24 is fixed on the slider or a threaded through hole is provided on the slider. The slider is threadedly connected to the screw through the nut 24 or its own threaded hole. The base 13 is provided with a limiting structure (e.g., a limiting groove) for limiting the rotation of the slider. The motor shaft can drive the screw to rotate in both the forward and reverse directions, thereby realizing the slider reciprocating along the screw, so that the slider pushes out or pulls back the movable rod 222. Under the action of the slider's pushing force, the movable rod 222 can first be pushed out laterally, and then flipped downwards by its own weight when pushed out to the end. Under the action of the slider's pulling force, the movable rod 222 can also first flip upwards, and then be further pulled back laterally into the base 13.

[0083] In this embodiment, without a gearbox, the threaded engagement between the screw and the movable component 22 not only improves the smoothness of the extension and retraction of the movable component 22 and the smoothness of the unfolding and retraction of the movable drying rod 30, but also enhances the load-bearing capacity of the movable drying rod 30 and the items drying on it. For example, when the movable drying rod 30 is used as a cover rod 31 to dry heavy autumn and winter quilts or multiple layers of clothing, on the one hand, the threaded engagement between the screw and the movable component 22 is similar to surface contact transmission. The threaded surface can evenly distribute the weight of the cover rod 31 and the clothing onto the external threaded surface of the screw, resulting in less force per unit area and avoiding deformation of the transmission components caused by local stress concentration. On the other hand, the self-locking characteristic of the threaded engagement can directly offset the reverse force generated by the load. Even if the weight of the items being dried is large, the slider will not slide in the opposite direction along the screw. Without relying on the locking structure of the gearbox or additional braking components, it can stably bear the load, ensuring that the movable drying rod 30 always remains in a suspended position without sagging or tilting. This not only ensures the safety of drying but also avoids transmission jamming due to insufficient load-bearing capacity, maintaining the smoothness of the movable drying rod 30's unfolding and retraction.

[0084] Even without a gearbox, the load-bearing capacity of the movable drying rod 30 can be improved, avoiding the large volume of the gearbox occupying the space of the base 13 and causing an increase in the external size of the base 13. The extension direction of the screw is consistent with the extension direction of the base 13, making the overall space more compact.

[0085] In other embodiments, the longitudinal transmission member 23 is a rack or the like extending along the length of the base 13. For ease of understanding, the longitudinal transmission member 23 will continue to be described as a screw in the following embodiments.

[0086] Optionally, continue to refer to Figure 10The driving component 21 is a drive motor, and the drive motor is a dual-head motor. The two ends of the dual-head motor have a first motor shaft 211 and a second motor shaft 212, respectively. When the dual-head motor is running, the two motor shafts rotate synchronously, for example, simultaneously clockwise or simultaneously counterclockwise. The two longitudinal transmission components 23 are a first screw 231 and a second screw 232, respectively. The first motor shaft 211 is connected to the first screw 231, and the second motor shaft 212 is connected to the second screw 232 through a steering transmission component 27. Thus, by using a single dual-head motor in conjunction with the steering transmission component 27, while the two motor shafts rotate in the same direction, the first screw 231 and the second screw 232 can rotate in opposite directions: when the first motor shaft 211 and the second motor shaft 212 rotate counterclockwise or clockwise at the same time, the first screw 231 and the second screw 232 can be driven to rotate in opposite directions (one rotates clockwise and the other rotates counterclockwise), thereby enabling the two movable components 22 on the same base 13 to retract inward or extend outward at the same time. This allows the two movable drying rods 30 connected to the ends of the two movable components 22 to retract inward or extend outward at the same time, thus synchronizing the movement of the two movable drying rods 30 and enhancing the stability and reliability of the drying rack when drying large items.

[0087] Optionally, the two screws are respectively connected to the two movable members 22 via two sets of transmission assemblies, one of which is equipped with the steering transmission element 27 in the above embodiment. Figure 10 The diagram illustrates that the first set of transmission components is used to realize the transmission connection between the drive motor and the first screw 231, and includes: a first input pulley 251, a first synchronous belt 252, and a first output pulley 253. The second set of transmission components is used to realize the transmission connection between the drive motor and the second screw 232, and includes: a second input pulley 261, a second synchronous belt 262, a second output pulley 263, and a steering transmission component 27, wherein the steering transmission component 27 is a steering transmission wheel.

[0088] The drive component 21 is connected to the first screw 231 in the following way: the first motor shaft 211 is coaxially connected to the first input wheel 251, the first input wheel 251 is connected to the first output wheel 253 through the first synchronous belt 252, and the first output wheel 253 is coaxially connected to the first screw 231.

[0089] One way in which the drive component 21 is connected to the second screw 232 is as follows: the second motor shaft 212 is coaxially connected to the second input wheel 261, the second input wheel 261 meshes with the steering transmission wheel, the steering transmission wheel is connected to the second output wheel 263 via the second synchronous belt 262, and the second output wheel 263 is coaxially connected to the second screw 232.

[0090] Another way to drive the drive component 21 and the second screw 232 is as follows: the second motor shaft 212 is coaxially connected to the second input wheel 261, the second input wheel 261 is connected to the steering transmission wheel through the second synchronous belt 262, the steering transmission wheel meshes with the second output wheel 263, and the second output wheel 263 is coaxially connected to the second screw 232.

[0091] In this embodiment, the two sets of transmission components can be arranged at the left and right ends of the base 13. The drive motor and two screws are arranged in the space between the two sets of transmission components. For example, the drive motor is located between the two transmission components and on the lower side, and the two screws are located between the two transmission components and on the upper side, so that the space inside the base 13 is compactly arranged and the transmission is stable.

[0092] For example, the left side of the first screw 231 is connected to the first motor shaft 211 below through a vertically arranged first set of transmission components, and the right side of the second screw 232 is connected to the second motor shaft 212 below through a vertically arranged second set of transmission components, which improves compactness while ensuring transmission stability.

[0093] In one embodiment, reference is made to Figure 7 The base 13 has an internal mounting cavity, in which the drive component 21 and the longitudinal transmission component 23 are both housed. This not only prevents external dust and moisture from corroding the core transmission component, but also prevents the user from directly contacting the moving parts, and improves the overall appearance of the drying rack when it is folded up. The mounting cavity includes a power mounting cavity 131 for accommodating the drive component 21, and a telescopic cavity 132 for accommodating the longitudinal transmission component 23 and the movable component 22.

[0094] Both longitudinal transmission components 23 are screws rotatably connected to the base 13, and each screw is connected to the drive component 21 so that it can rotate under the drive of the drive component 21 and drive the corresponding movable component 22 to extend and retract relative to the base 13.

[0095] The movable component 22 has a rod hole 2201 inside, and a nut 24 is installed on the movable component 22. The nut 24 is threadedly connected to the screw. This threaded connection can accurately convert the rotational motion of the screw into the linear extension and retraction motion of the movable component 22, ensuring that the movable component 22 moves smoothly without jamming.

[0096] When both movable components 22 are retracted into the base 13, each screw passes through the corresponding rod hole 2201, so that each movable component 22 is fitted onto the outside of the corresponding screw. This nested structure greatly reduces the space occupied by both in the mounting cavity.

[0097] In one embodiment, reference is made to Figure 9The drying rack also includes a first mounting bracket 141 and a second mounting bracket 142 disposed on the base 13. The two mounting brackets are respectively arranged near both ends of the base 13 along its length. The base 13 also has end openings at both ends along its length for the two movable components 22 to extend from both ends. By setting mounting brackets at both ends in the mounting cavity, subsequent drive and transmission components can be precisely positioned and installed. At the same time, the end openings provide a channel for the extension and retraction of the movable components 22, avoiding interference between the movable components 22 and other structures of the base 13, and ensuring the stability of the extension and retraction path.

[0098] The drive component 21 includes a drive motor, which is mounted on the first mounting bracket 141 or the second mounting bracket 142; or, the drive component 21 includes two drive motors, which are respectively mounted on the first mounting bracket 141 and the second mounting bracket 142.

[0099] Optionally, the two longitudinal transmission components 23 are a first screw 231 and a second screw 232, respectively. The first screw 231 is rotatably connected to the first mounting bracket 141, and the second screw 232 is rotatably connected to the second mounting bracket 142.

[0100] Optionally, the first set of transmission components is mounted on the first mounting bracket 141, and the second set of transmission components is mounted on the second mounting bracket 142.

[0101] Optionally, the first set of movable components 22 is threadedly connected to the first screw 231 and slidably connected to the second mounting bracket 142. The second set of movable components 22 is threadedly connected to the second screw 232 and slidably connected to the first mounting bracket 141.
