Description

Technical Field

[0001] This utility model relates to a clothes drying rack, and more particularly to a four-bar clothes drying rack, in which a drying bar is set in each of the four directions of the drying area below the clothes drying rack, thereby increasing the amount of clothes that can be dried. Background Technology

[0002] Existing clothes drying racks include a main unit mounted on the ceiling and a retractable drying rod device below;

[0003] The existing main unit is rectangular; there are two types of drying rod devices. One type has rod seats, and two parallel drying rods are connected by two rod seats. In order to improve the stability of lifting and lowering, a folding frame is set between the drying rod device and the main unit; this type of drying rod device has a larger drying capacity.

[0004] Another type is the single drying rod, where the two ends of a steel wire rope are connected to the ends of the drying rod. This type has a relatively small drying capacity. To increase the drying capacity, some systems use a single main unit for two parallel single drying rods. Each drying rod has its own drive mechanism to raise and lower its respective rod. The extension direction of each single drying rod is consistent with the length direction of the main unit. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a four-bar clothes drying machine with a clothes drying bar in each of the four directions of the drying area.

[0007] The host is equipped with a first drive device, a second drive device, a third drive device, and a control device.

[0008] The four drying poles include a first drying pole and a second drying pole that are parallel to the first side length, and a third drying pole and a fourth drying pole that are parallel to the second side length.

[0009] The first driving device drives the first drying rack to rise and fall by retracting and extending the first steel wire rope; the second driving device drives the second drying rack to rise and fall by retracting and extending the second steel wire rope; the third driving device drives the third and fourth drying racks to rise and fall accordingly by retracting and extending the third and fourth steel wire ropes.

[0010] A further preferred technical solution of this utility model is: when the four drying rods are at the same height, the four drying rods form a rectangular structure, which corresponds to the four sides of the rectangular host respectively.

[0011] A further preferred embodiment of this utility model is as follows: the first driving device includes a first motor and two first stranded reels, the first motor drives the rotation of the two first stranded reels through a first transmission mechanism; the two steel wire ropes wound and unwound by the first stranded reels are connected to the two ends of the first drying rod.

[0012] A further preferred technical solution of this utility model is as follows: the second driving device includes a second motor and two second stranded coils. The second motor drives the rotation of the two second stranded coils through a second transmission mechanism. The two steel wire ropes wound and unwound by the second stranded coils are connected to the two ends of the second drying rod.

[0013] A further preferred embodiment of this utility model is as follows: the third driving device includes a third motor, two third stranded coils, and two fourth stranded coils, wherein the third motor drives the third stranded coils and the fourth stranded coils simultaneously through a third transmission mechanism;

[0014] The two steel wire ropes wound up and down by the third stranding reel are connected to the two ends of the third drying rod, and the two steel wire ropes wound up and down by the fourth stranding reel are connected to the two ends of the fourth drying rod.

[0015] A further preferred embodiment of this invention is as follows: the two third stranded coils and the two fourth stranded coils are arranged in a rectangular structure; adjacent stranded coils are meshed by gears to achieve synchronous rotation of the four stranded coils.

[0016] A further preferred embodiment of this utility model is as follows: the third driving device is located in the middle of the main unit base plate, and the first driving device and the second driving device are located on both sides of the third driving device; the control device is located on the front side of the third driving device.

[0017] A further preferred embodiment of this utility model is: four steering wheels are provided at each end of the base plate of the host computer;

[0018] The first wire rope, drawn from the first drive device, passes through the first steering wheel and is vertically downward connected to the end of the first drying rod; the second wire rope, drawn from the second drive device, passes through the second steering wheel and is vertically downward connected to the end of the second drying rod; the third wire rope, drawn from the third drive device, passes through the third steering wheel and is vertically downward connected to the end of the third drying rod; and the fourth wire rope, drawn from the third drive device, passes through the fourth steering wheel and is vertically downward connected to the end of the fourth drying rod.

[0019] A further preferred embodiment of this invention is that the control device includes a wireless remote control module, allowing users to remotely control the raising and lowering of the drying rack via a remote control or an application on a mobile device.

[0021] Compared with existing technologies, the advantages of this invention are: the four-pole clothes drying rack adopts a rectangular main unit design and cleverly arranges four drying poles, with the first and second poles parallel to the first side of the main unit, and the third and fourth poles parallel to the second side. This layout makes full use of the space below the main unit, forming a highly efficient clothes drying area. Compared with traditional single-pole or double-pole clothes drying racks, the four-pole design significantly increases the amount of clothes that can be dried, meeting the drying needs of more clothes simultaneously and greatly improving drying efficiency. It is especially suitable for home users to dry a large number of clothes in limited space.

[0022] The main unit is equipped with first, second, and third drive mechanisms, each controlling the raising and lowering of the four drying rods by extending and retracting corresponding steel cables. This independent drive system allows for more flexible and precise raising and lowering of each rod, enabling independent adjustment of the rod's height according to the drying needs of different garments. Furthermore, the drive mechanisms do not interfere with each other, ensuring stability during the raising and lowering process and preventing swaying or jamming caused by multiple rods raising and lowering simultaneously.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0032] like Figures 1 to 3 As shown, the four-bar clothes drying rack 100 has a core structure consisting of a rectangular main unit 10 and four drying rods 20. The main unit 10 is designed to be rectangular, with a first side length 11 and a second side length 12, wherein the first side length 11 is significantly larger than the second side length 12. This unique size ratio provides an ideal basis for the layout of the drying rods and the clothes drying function.

[0033] Inside the main unit 10, a first drive device 31, a second drive device 32, a third drive device 33, and a control device 34 are arranged in a reasonable manner. These devices work together to realize flexible lifting and lowering control of the drying rack, providing users with a convenient clothes drying experience.

[0034] The layout of the four drying rods 20 is carefully designed to maximize drying space and functionality. Specifically, the first drying rod 21 and the second drying rod 22 are parallel to the first side length 11 of the main unit, while the third drying rod 23 and the fourth drying rod 24 are parallel to the second side length 12 of the main unit. This layout allows the drying rods to work together spatially, forming an efficient drying area.

[0035] Regarding the raising and lowering control of the clothes drying racks, the first drive device 31 precisely drives the raising and lowering of the first drying rack 21 by winding and releasing the first steel wire rope s1; the second drive device 32 controls the raising and lowering of the second drying rack 22 by winding and releasing the second steel wire rope s2; and the third drive device 33 drives the raising and lowering of the third drying rack 23 and the fourth drying rack 24 respectively by winding and releasing the third steel wire rope s3 and the fourth steel wire rope s4. This independent drive method not only improves the flexibility of raising and lowering the drying racks but also enhances the stability and reliability of the clothes drying rack.

[0036] To further enhance the performance and user experience of the clothes drying rack, this technical solution can also incorporate several other innovative improvements. For example, the spacing between the drying rods can be adjusted to accommodate various sizes of clothing according to different users' drying needs. Furthermore, the surface of the drying rods is treated with an anti-slip coating to effectively prevent clothing from slipping during drying, ensuring that clothing hangs securely on the rods. The length of the drying rods can also be adjusted for extension and retraction according to actual usage scenarios, further improving the applicability and flexibility of the clothes drying rack. Multiple steering wheels are also installed at both ends of the base plate of the main unit. These wheels not only facilitate the smooth guidance of the wire rope but also reduce wear on the wire rope during operation, extending the service life of the clothes drying rack.

[0037] The control device 34, as the core control unit of the clothes drying rack, possesses intelligent control functions. It can connect to the user's mobile device or remote control via a wireless remote control module to remotely control the raising and lowering of the drying rod. Preferably, the control device is also equipped with multiple sensors that can detect the current position and load of the drying rod in real time and feed this information back to the control device. Based on the sensor feedback signals, the control device automatically adjusts the raising and lowering speed and stopping position of the drying rod, ensuring the automation and intelligence of the clothes drying process.

[0038] Through the above optimizations and expansions, the four-pole clothes drying rack 100 is not only more structurally sound but also more functionally complete, meeting the drying needs of different users in various environments and providing users with an efficient, convenient, and reliable clothes drying solution.

[0039] Specifically, when the four drying rods 20 are at the same height, they connect with each other in space and form a rectangular structure. This structure cleverly corresponds to the four sides of the rectangular main unit 10, creating a unique spatial layout. This layout not only makes full use of the drying area below the main unit 10, but also ensures the stability and balance of the drying rods during the lifting and lowering process through the parallel relationship between the length of the drying rods and the side length of the main unit.

[0040] More specifically, the first drying rod 21 and the second drying rod 22 are parallel to the first side length 11 of the main unit 10, while the third drying rod 23 and the fourth drying rod 24 are parallel to the second side length 12 of the main unit 10. This ensures that the drying rods maintain their relative position to the main unit during raising and lowering, avoiding mutual interference between the drying rods and between the drying rods and the main unit, thereby improving the overall performance and service life of the clothes dryer. At the same time, this rectangular-shaped drying rod layout provides users with more drying space, enabling the clothes dryer to meet the drying needs of more clothes, further enhancing its practicality and functionality.

[0041] The drive mechanism of the four-pole clothes drying rack 100 is rationally laid out, ensuring the stability and precision of the clothes rod raising and lowering. For example... Figures 4 to 6As shown, the first drive device 31 consists of a first motor 311 and two first stranded wire reels 312. The first motor 311 drives the two first stranded wire reels 312 to rotate through the first transmission mechanism 41, thereby realizing the lifting and lowering control of the first drying rod 21. The two steel wire ropes that are wound and released by the first stranded wire reels 312 are respectively connected to the two ends of the first drying rod 21, which ensures the balance and stability of the drying rod during the lifting and lowering process.

[0042] The structure of the second drive device 32 is similar to that of the first drive device, including a second motor 321 and two second stranded wire reels 322. The second motor 321 drives the two second stranded wire reels 322 to rotate through the second transmission mechanism 42, thereby controlling the raising and lowering of the second drying rod 22. The two steel wire ropes that are wound and released by the second stranded wire reels 322 are connected to the two ends of the second drying rod 22. This layout also ensures the smooth operation of the drying rod during the raising and lowering process.

[0043] The third drive unit 33 is relatively complex in its design to achieve synchronous lifting and lowering of the third drying rod 23 and the fourth drying rod 24. The third drive unit 33 includes a third motor 331, two third twisted wire reels 332, and two fourth twisted wire reels 333. The third motor 331 drives both the third and fourth twisted wire reels 332 simultaneously via a third transmission mechanism 43. The two wire ropes wound and unwound by the third twisted wire reels 332 connect to both ends of the third drying rod 23, while the two wire ropes wound and unwound by the fourth twisted wire reels 333 connect to both ends of the fourth drying rod 24. To ensure synchronous rotation of the four twisted wire reels, the two third twisted wire reels 332 and the two fourth twisted wire reels 333 are arranged in a rectangular structure, with adjacent reels meshing through gears. This not only improves the synchronicity of the drying rod lifting and lowering but also enhances the stability and reliability of the entire system.

[0044] With its rationally designed drive mechanism, the four-bar clothes dryer 100 allows for independent control and flexible raising and lowering of all four drying bars, meeting users' drying needs in various scenarios. Each drive unit is equipped with a dedicated motor and winding reel, ensuring the precision and stability of the bar raising and lowering. Simultaneously, the synchronous rotation mechanism achieved through gear meshing further enhances the overall performance of the clothes dryer, making it more efficient and convenient to use.

[0045] Preferably, the third drive device 33 is located in the middle of the base plate of the main unit, so that it can drive the lifting and lowering of the third drying rod 23 and the fourth drying rod 24 more evenly, ensuring the synchronicity and stability of the two drying rods during the lifting and lowering process.

[0046] The first drive unit 31 and the second drive unit 32 are located on either side of the third drive unit 33; this distribution makes the entire drive system more compact and efficient in space. It not only optimizes the internal space utilization of the main unit but also minimizes mutual interference between the drive units. During the raising and lowering of the clothesline, each drive unit can work independently and efficiently without interfering with the others, further improving the performance and reliability of the clothes dryer.

[0047] Preferably, the control device 34 is positioned in front of the third drive device 33. This simplifies the connection wiring between the control device and the drive device, reducing wiring complexity and signal transmission interference. Furthermore, it allows for a more compact and orderly layout of components on the main unit's backplane. This layout makes full use of the space on the main unit's backplane, avoiding mutual interference and crowding between components.

[0048] Preferably, to further optimize and improve the performance and reliability of the four-bar clothes drying rack, four steering wheels 60 are provided at each end of the base plate of the main unit 10. The arrangement of these steering wheels 60 not only provides a precise path for guiding the wire rope, but also effectively reduces the friction and wear of the wire rope during operation, significantly extending the service life of the wire rope, while ensuring the stability and smoothness of the lifting and lowering process of the drying rod.

[0049] Specifically, the first wire rope s1, which is led out from the first drive device 31, is precisely and vertically connected to the end of the first drying rod 21 after being guided by the first steering wheel; similarly, the second wire rope s2, which is led out from the second drive device 32, is also vertically connected to the end of the second drying rod 22 under the guidance of the second steering wheel; the third wire rope s3 and the fourth wire rope s4, which are led out from the third drive device 33, are vertically connected to the ends of the third drying rod 23 and the fourth drying rod 24 after being guided by the third steering wheel and the fourth steering wheel, respectively.

[0050] This ingenious arrangement of steering wheels and the connection method of steel wire ropes together create an efficient and stable clothes drying rack lifting system, providing users with a more convenient and reliable clothes drying experience.

[0051] Preferably, the four drying rods 20 are distributed at non-equal intervals in the drying area below the main unit 10, wherein the distance between the first drying rod 21 and the second drying rod 22 is greater than the distance between the third drying rod 23 and the fourth drying rod 24, so as to optimize the space utilization efficiency of the drying area.

[0052] The four drying rods 20 are symmetrically distributed in the drying area below the main unit 10. The first drying rod 21 and the second drying rod 22 are symmetrical about the center line of the main unit 10, and the third drying rod 23 and the fourth drying rod 24 are also symmetrical about the center line of the main unit 10, so as to ensure the overall balance and stability of the clothes drying machine.
