Description

Technical Field

[0001] This invention relates to an electric clothes drying rack, and more particularly to an electric clothes drying rack that automatically adjusts the spacing between clothes; during drying, the clothes can be automatically spread out on the drying rod; when drying is complete, the clothes can be gathered together on the drying rod for easy collection. Background Technology

[0002] Currently, both traditional clotheslines and those on clothes drying machines have multiple fixed hanging holes on the rod, spaced apart and in fixed positions. When drying clothes, each garment is hung on its corresponding hole via a clothes rack. Once the clothes are dry, taking them down is relatively inconvenient.

[0003] To address the aforementioned issues, a clothes drying rack assembly (publication number CN208586438U) includes a drying rod, connecting ropes, and several hanging hole assemblies. These hanging hole assemblies are distributed along the length of the track, and adjacent assemblies are connected by the connecting ropes. This movable assembly of hanging holes allows for flexible hanging of clothing, not only meeting the need for convenient clothes collection but also enabling dispersed drying.

[0004] The clothes drying assembly and system of CN212834640U allows users to slide the drying assembly as needed to make adjacent sliding parts unfold or come together in conjunction. When adjacent sliding parts come together, the flexible connecting rope that has been folded can be gathered in the storage cavity, so that the various drying assemblies are more tightly packed together.

[0005] The existing hanging hole assembly still requires manual operation to gather and disperse, which is relatively troublesome. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an electric clothes drying rack that automatically adjusts the spacing between clothes, automatically disperses and gathers clothes, and improves the efficiency of drying clothes.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an electric clothes drying rack that automatically adjusts the spacing between clothes, including a main unit and a height-adjustable drying rod, wherein the end of the main unit is provided with an upper coupling driven by a motor;

[0008] The first end of the drying rod is provided with a lower coupling and a main gear, and the main gear is coaxially located on the lower side of the lower coupling;

[0009] The tail end of the drying rod is equipped with a driven gear;

[0010] The drying rod is provided with a straight groove extending along the length of the drying rod and an annular groove surrounding the straight groove. Multiple hanging rings are provided in the straight groove; a belt is provided in the annular groove, and the belt is connected to the main gear and the driven gear.

[0011] The first hanging ring is fixed in the groove of the drying rod; adjacent hanging rings are connected by a soft wire, and the last hanging ring is connected to the belt;

[0012] The lower end face of the upper coupling is provided with a first tooth, and the upper end face of the lower coupling is provided with a second tooth;

[0013] When the drying rack is raised to its upper limit, the first tooth of the upper coupling and the second tooth of the lower coupling mesh. The motor drives the upper and lower couplings and drives the belt to move back and forth, which can drive the last hanging ring to move back and forth in the linear slide groove, thereby causing all the hanging rings to disperse and retract on the drying rack.

[0014] A further preferred embodiment of the present invention is as follows: the annular groove includes arc-shaped grooves located at both ends of the drying rod and a straight belt groove located outside the straight slide groove; a partition is provided between the straight belt groove and the straight slide groove, and a through groove is provided in the middle of the partition;

[0015] The belt is connected to the last hanging ring via a transverse connecting part. When the belt slides, the transverse connecting part can slide along the groove.

[0016] A further preferred embodiment of the present invention is as follows: the hanging ring is a slider with a movable wheel installed, the upper end surface of the slider is higher than the upper surface of the drying rod, and the upper end surface of the slider is a concave arc surface.

[0017] A further preferred embodiment of the present invention is that the motor is driven by the upper coupling through a gear set.

[0018] A further preferred embodiment of the present invention is as follows: the lower coupling is located at the bottom of the cylindrical part, and when the upper coupling is connected to the lower coupling, the peripheral wall of the upper coupling enters the concave cavity of the cylindrical part.

[0019] A further preferred embodiment of the present invention is as follows: there is a gap between the outer periphery of the lower coupling and the inner wall surface of the cylindrical part, the peripheral wall of the upper coupling matches the gap, the top surface of the cylindrical part is a conical surface with the outer periphery higher than the inner surface, and the outer ring of the peripheral wall of the upper coupling is adapted to the top surface of the cylindrical part.

[0020] A further preferred embodiment of the present invention is as follows: the first tooth and the second tooth have the same structure. The second tooth includes multiple tooth surfaces, which surround to form a circular structure. The tooth surfaces are arranged in an inclined fan shape. Each tooth surface includes a protruding side and a connecting side. The protruding side of the tooth surface is higher than the connecting side. The protruding side of the tooth surface and the outer peripheral surface are transitioned by a rounded angle.

[0021] A further preferred embodiment of the present invention is: a compression spring is provided between the upper coupling and the main machine, and the compression spring applies a downward thrust to the upper coupling;

[0022] The compression spring drives the upper coupling to extend downward a certain distance, and the lower coupling rises to contact the upper coupling and drives the upper coupling to rise back.

[0023] A further preferred embodiment of the present invention is as follows: the inner side of the belt has regularly arranged wheel teeth, one end of the transverse connecting part is connected to the last hanging ring, and the other end of the transverse connecting part is connected to the engagement block. The engagement block is installed on the belt and meshes with the wheel teeth on the belt. The moving belt drives the last hanging ring to move along the straight groove through the transverse connecting part.

[0024] Finally, when the hanging ring is moved towards the end of the drying rod, it pulls the adjacent hanging rings one by one through the soft line, and multiple hanging rings are unfolded; when the hanging ring is moved towards the beginning of the drying rod, it moves and contacts the adjacent hanging rings one by one, pushing the hanging rings to retract.

[0025] A further preferred embodiment of the present invention is as follows: the cross-section of the straight belt groove is a rectangular frame structure, the belt is installed in the straight belt groove, and the through groove is opened on the adjacent side of the straight belt groove and the straight slide groove.

[0026] The straight slide has a rectangular frame structure in cross-section, and the top surface of the straight slide has a slot for the upper end face of the slider to pass through. The moving wheel is located inside the straight slide.

[0027] Compared with existing technologies, the advantages of this invention are: its automatic dispersion and retraction functions greatly improve drying efficiency, reduce the tedium of manual operation, and make the drying process faster and more convenient. Secondly, the motor-driven clutch system enables precise control of the hanging rings on the clothesline, ensuring even distribution of clothing and optimizing space utilization. Furthermore, the linear and annular groove designs on the clothesline, combined with belt drive, allow the hanging rings to move smoothly on the clothesline, reducing operating noise and extending the machine's lifespan. Finally, this design is highly adaptable, suitable for clothing of different lengths and weights, meeting diverse drying needs. Overall, this patent provides an efficient, convenient, quiet, and durable electric clothes drying solution. Attached Figure Description

[0041] 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 the invention.

[0042] 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.

[0043] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Similarly, "first" and "second" are only for ease of understanding and have no other directional meaning, and should not be considered as limitations on this invention.

[0044] An electric clothes drying rack that automatically adjusts the spacing between clothes, as described in Embodiment 1 Figures 1 to 7 As shown, the device includes a main unit 1 and a height-adjustable drying rod 2. The end of the main unit 1 is provided with an upper coupling 3 driven by a motor 8; the beginning end of the drying rod 2 is provided with a lower coupling 4 and a main gear 5, with the main gear 5 coaxially located on the lower side of the lower coupling 4; the tail end of the drying rod 2 is provided with a driven gear; the lower end face of the upper coupling 3 is provided with a first tooth 12, and the upper end face of the lower coupling 4 is provided with a second tooth 13.

[0045] When the drying rod 2 is raised to the upper limit, the first tooth 12 of the upper coupling 3 and the second tooth 13 of the lower coupling 4 mesh. The motor 8 drives the upper and lower couplings 4 and drives the belt 10 to move back and forth, which can drive the last hanging ring 9 to move back and forth in the linear slide groove 7, thereby driving all the hanging rings 9 to disperse and retract on the drying rod 2.

[0046] In this invention, no power unit is installed inside the drying rod 2. Instead, the motor 8 is integrated into the main unit 1, with an upper coupling 3, and a corresponding lower coupling 4 is installed on the drying rod 2. When the upper coupling 3 and the lower coupling 4 mesh, the motor 8 drives the lower coupling 4 on the drying rod 2 to rotate, which in turn drives the main gear 5 to rotate. When the drying rod 2 moves away from its upper limit position, the lower coupling 4 loses its force and is in a free state, allowing the lower gear to rotate freely. In other words, after the drying rod 2 is lowered, the user can manually pull the hanging ring 9 on the drying rod 2, making it convenient for the user and adapting to their usage habits.

[0047] The drying rod 2 is provided with a straight groove 7 extending along the length of the drying rod 2 and an annular groove surrounding the straight groove 7. Multiple hanging rings 9 are provided in the straight groove 7. A belt 10 is provided in the annular groove. The belt 10 is connected to the main gear 5 and the driven gear. The first hanging ring 9 is fixed in the groove of the drying rod 2. Adjacent hanging rings 9 are connected by a flexible wire 11. The last hanging ring 9 is connected to the belt 10.

[0048] In this invention, a straight groove 7 extending along the length of the drying rod 2 is designed on the drying rod 2 for installing multiple hanging rings 9, and an annular groove surrounding the straight groove 7 is designed for installing a belt 10. The rotation of the main gear 5 drives the belt 10 and the driven gear to rotate. The movement of the belt 10 drives the opening and closing of the hanging rings 9. Specifically, this invention can be set so that when the drying rod 2 is lowered (generally when the user needs to hang or take down clothes), the motor 8 works to close the multiple hanging rings 9 to the first end of the drying rod 2. The user only needs to stand in place to hang the clothes that need to be hung on the multiple hanging rings 9, or take down the clothes that have already dried. When the clothes drying rod is raised to the upper limit, the motor 8 works, and the multiple hanging rings 9 pull each other and disperse on the drying rod 2, so that the clothes hanging on the hanging rings 9 are evenly dispersed, achieving ventilation and accelerating drying.

[0049] The motor 8 is driven by the upper coupling 3 via a gear set 21. This gear set allows for adjustments to the motor 8's speed according to actual needs before outputting power to the upper coupling 3. The gear set 21 provides greater flexibility in selecting the motor 8. It also increases output torque, meeting different load requirements and improving the system's load-bearing capacity.

[0050] Example 2, as Figures 1 to 7 As shown, the lower coupling 4 is located at the bottom of the cylindrical portion 22. When the upper coupling 3 mates with the lower coupling 4, the peripheral wall of the upper coupling 3 enters the cavity of the cylindrical portion 22. The cavity design of the cylindrical portion 22 effectively guides the upper coupling 3 and the lower coupling 4 to accurately mate, ensuring the alignment of the axes of the upper and lower couplings and avoiding eccentricity and runout. Furthermore, the entry of the upper coupling 3 into the cavity of the cylindrical portion 22 through the peripheral wall provides radial support, increasing the rigidity and stability of the connection and reducing vibration during operation.

[0051] There is a gap between the outer periphery of the lower coupling 4 and the inner wall of the cylindrical part 22. The peripheral wall of the upper coupling 3 matches this gap. The top surface of the cylindrical part 22 has an outer conical surface 23 that is higher than the inner surface. The outer ring of the peripheral wall of the upper coupling 3 is adapted to the top surface of the cylindrical part 22. In this invention, the top surface of the cylindrical part 22 is designed as a conical surface 23, which serves as a positioning and guiding function. Combined with the correspondingly designed peripheral wall of the upper coupling 3, the upper coupling 3 can automatically align itself, achieving centering between the upper coupling 3 and the lower coupling 4, thus improving the reliability and efficiency of the connection. When the upper coupling 3 and the lower coupling 4 are connected, the peripheral wall of the upper coupling 3 is sleeved on the outer periphery of the lower gear part, and the cylindrical part 22 is sleeved on the outer periphery of the upper coupling 3.

[0052] The first tooth 12 and the second tooth 13 have the same structure. The second tooth 13 includes multiple tooth surfaces 24, which form a circular structure. The tooth surfaces 24 are inclined fan-shaped and include a protruding side 24a and a connecting side 24b. The protruding side 24a of the tooth surface 24 is higher than the connecting side 24b, and the protruding side 24a of the tooth surface 24 transitions to the outer peripheral surface with an arc angle 24c. Because the lower coupling 4 is in a free state after disengagement, it will rotate under external force. Therefore, when the lower coupling 4 rises again to engage with the upper coupling 3, the first tooth 12 and the second tooth 13 may be misaligned. Continuing to force an upward movement at this time will cause the first tooth 12 and the second tooth 13 to break. To address this problem, the present invention adopts a tooth-shaped configuration. That is, the tooth surface 24 is inclined fan-shaped, and the protruding side 24a of the tooth surface 24 transitions to the outer peripheral surface with an arc angle 24c. When the first tooth 12 and the second tooth 13 are misaligned and meshed, the arc angle 24c will press against the inclined fan surface. Under the action of pressure, the arc angle 24c slides against the fan surface until the fan surface of the first tooth 12 and the fan surface of the second tooth 13 are in contact.

[0053] A compression spring 25 is provided between the upper coupling and the main unit 1. The compression spring 25 applies a downward thrust to the upper coupling 3. The compression spring 25 drives the upper coupling 3 to extend downward a certain distance, and the lower coupling 4 rises to contact the upper coupling 3 and drives the upper coupling 3 to rise back. This invention increases the elasticity of the upper coupling 3 during engagement by providing the compression spring 25. The initial contact between the upper and lower couplings acts as a buffer, making it a soft connection and reducing wear between gears. At the highest point of return, it eliminates the clearance between the upper and lower couplings.

[0054] The rest of the contents of Example 2 are the same as those of Example 1.

[0055] Example 3, as Figures 1 to 11As shown, the annular groove includes arc-shaped grooves 14 at both ends of the drying rod 2 and a straight belt groove 15 located outside the straight slide groove 7; a partition 16 is provided between the straight belt groove 15 and the straight slide groove 7, and a through groove 17 is provided in the middle of the partition 16; the belt 10 is connected to the last hanging ring 9 through a transverse connecting part 18, and when the belt 10 slides, the transverse connecting part 18 can slide along the through groove 17.

[0056] This invention achieves the installation and limiting of the belt 10 by setting an annular groove, ensuring that the belt 10 can move along a predetermined trajectory. The installation and limiting of the hanging rings 9 are achieved by setting a linear slide groove 7, ensuring that the hanging rings 9 can move along the length of the drying rod 2 and preventing swaying. Furthermore, a partition 16 separates the linear belt groove 15 and the linear slide groove 7, preventing the belt 10 and the hanging rings 9 from interfering with each other. In this invention, the belt 10 only needs to drive the last hanging ring 9 to slide to achieve the unfolding or retraction of all hanging rings 9. Therefore, a groove 17 is designed on the partition 16, and a transverse connecting part 18 is provided to connect the belt 10 to the last hanging ring 9, realizing the driving of multiple hanging rings 9.

[0057] The inner surface of the belt 10 has regularly arranged gear teeth 26. One end of the transverse connecting part 18 is connected to the last hanging ring 9, and the other end of the transverse connecting part 18 is connected to the engaging block 27. The engaging block 27 is installed on the belt 10 and engages with the gear teeth 26 on the belt 10. The moving belt 10 drives the last hanging ring 9 to move along the straight slide groove 7 through the transverse connecting part 18. When the last hanging ring 9 is subjected to force and moves towards the tail of the drying rod 2, it pulls the adjacent hanging rings 9 one by one through the soft line 11, and multiple hanging rings 9 are unfolded. When the last hanging ring 9 is subjected to force and moves towards the head of the drying rod 2, it moves and contacts the adjacent hanging rings 9 one by one, pushing the hanging rings 9 to retract.

[0058] The straight belt groove 15 has a rectangular frame structure in cross-section. The belt 10 is installed inside the straight belt groove 15, and the through groove 17 is formed on the adjacent side of the straight belt groove 15 and the straight slide groove 7. The straight belt groove 15 neatly houses the belt 10, preventing the belt 10 from being exposed and accidentally touched by the user. It also prevents dust and foreign objects from the external environment from entering the belt 10, causing abnormal noise or blockage when the belt 10 moves.

[0059] The linear slide 7 has a rectangular frame structure in cross-section. The top surface of the linear slide 7 has a slot through which the upper end of the slider 20 passes. The moving wheel 19 is located inside the linear slide 7. Similarly, the structure of the linear slide 7 also houses the lower ends of the moving wheel 19 and the slider 20, preventing them from being exposed and accidentally touched by the user, and also preventing dust and foreign objects from entering.

[0060] The hanging ring 9 is a slider 20 equipped with a movable wheel 19. The upper surface of the slider 20 is higher than the upper surface of the drying rod 2, and the upper surface of the slider 20 is a concave arc surface. When the drying rod 2 is raised to its upper limit, there is a gap between the hanging ring 9 and the main unit 1, which can accommodate the hanging of the clothes hanger. Specifically, the upper surface of the slider 20 can be a wave-shaped structure, including crests and troughs. When the clothes hanger is suspended on the upper surface of the slider 20, the clothes hanger will naturally fall to the trough and be limited by the crests on both sides.

[0061] The present invention features a movable wheel 19 on the hanging ring 9. The movable wheel 19 effectively reduces the frictional resistance when the hanging ring 9 moves, making the hanging ring 9 move smoothly. Whether the user pushes or pulls manually or it is driven by the motor 8, the hanging ring 9 can be moved easily.

[0062] The other contents of Example 3 are the same as those of Example 1 or Example 2.
