[0032] The utility model provides a drying bracket.

[0033] In an embodiment of the present utility model, please refer to Figures 1 to 8. The drying bracket includes a shell 10, a clothesline 20 and a sealing structure 30. The shell 10 is formed with a heating chamber 11 and a connecting through-hole 12 connected to the heating chamber 11; the clothesline 20 is provided with an air guide channel 21, an air inlet 22 and an air outlet 23, and the air inlet 22 and the air outlet 23 are respectively connected to the air guide channel 21; the clothesline 20 has an unfolded state and a retracted state. As shown in Figure 1, in the unfolded state, the clothesline 20 is located outside the shell 10 and is open relative to the shell 10, the air inlet 22 is connected to the connecting through-hole 12, and the sealing structure 30 seals the clothesline 20 and the connecting through-hole 12; as shown in Figures 5 to 7, in the retracted state, the clothesline 20 is received in the heating chamber 11; the sealing structure 30 blocks the connecting through-hole 12.

[0034] The drying rack is a device that dries wet clothes by converting cold air into hot air. Please refer to Figure 8 , where the arrows indicate the direction of hot air flow, U indicates rising hot air, and D indicates descending hot air. In this embodiment, cold air enters the housing 10 and is converted into hot air in the heating chamber 11. After rising, the hot air enters the air guide channel 21 from the air inlet 22 and is discharged from the air outlet 23 to dry the clothes hung or placed on the clothesline 20. If the air outlet 23 is located at the bottom of the housing 10, the multiple pieces of clothing hung on the clothesline 20 may move in the direction of the wind under the influence of the wind. The gaps between the multiple pieces of clothing are too small, and they cannot be heated evenly, resulting in some clothes being completely dry and others being wet, or one piece of clothing being partially dry and partially wet. In this embodiment, please refer to Figures 1 to 4 , the air outlet 23 is located on the clothesline 20 so that multiple pieces of clothing can be heated evenly, preventing some clothes from being partially dry and others from being wet. In the unfolded state, the sealing structure 30 seals the clothes drying rod 20 and the connecting hole 12, thereby preventing heat loss and hot air from burning the user's skin. In the retracted state, the sealing structure 30 blocks the connecting hole 12, thereby preventing dust from contaminating the clothes drying rod 20 and facilitating the next use.

[0035] In one embodiment, referring to Figures 1 to 4 , the sealing structure 30 includes a first sealing sheet 31 disposed at one end of the clothes drying rod 20. The first sealing sheet 31 defines an air inlet 22. When deployed, the first sealing sheet 31 seals against the inner surface of the housing 10. The sealing contact of the first sealing sheet 31 against the inner surface of the housing 10 may include, but is not limited to, contacting the surface of the first sealing sheet 31 against the inner surface of the housing 10, or contacting the peripheral edge of the first sealing sheet 31 against the wall edge of the connecting through-hole 12.

[0036] Further, referring to Figures 1 to 4 , the sealing structure 30 further includes a second sealing sheet 32, which is disposed at the other end of the clothes drying rod 20. In the retracted state, the second sealing sheet 32 ​​seals against the outer surface of the housing 10. The sealing contact of the second sealing sheet 32 ​​against the outer surface of the housing 10 includes, but is not limited to, the surface of the second sealing sheet 32 ​​abutting against the outer surface of the housing 10, or the periphery of the second sealing sheet 32 ​​abutting against the edge of the wall of the connecting through-hole 12.

[0037] 1 , the second sealing sheet 32 ​​is provided with a handle 321, which is located outside the housing 10. The handle 321 includes, but is not limited to, a ring or a pancake shape. Providing the handle 321 on the second sealing sheet 32 ​​facilitates the user in unfolding or folding the clothesline 20.

[0038] In one embodiment, please refer to Figures 2, 5 and 6. A plurality of connecting through holes 12 are arranged at intervals along the periphery of the shell 10; a limiting structure 13 is provided on the upper surface of the shell 10 corresponding to each connecting through hole 12, and the limiting structure 13 forms a limiting groove 131 with a notch facing away from the outer surface of the shell 10; in the unfolded state, the clothes drying rod 20 is overlapped with the limiting groove 131 from the notch, and the clothes drying rod 20 is spaced apart from the outer surface of the shell 10.

[0039] During the use of the drying rack 100, hot air flows in the air guide channel 21 of the clothes drying rod 20, causing the temperature of the clothes drying rod 20 to continue to rise. If the clothes drying rod 20 is directly overlapped on the top of the shell 10 at this time, the shell 10 may be damaged. If the clothes drying rod 20 is columnar, the clothes drying rod 20 may roll on the top of the shell 10. This is inconvenient for users to dry clothes, and it also affects the overall stability of the drying rack 100, causing the drying rack 100 to tip over. In this embodiment, in the unfolded state, the clothes drying rod 20 is overlapped in the limiting groove 131 from the notch, and the clothes drying rod 20 is spaced apart from the outer surface of the shell 10. In this way, it is possible to prevent the clothes drying rod 20 from scalding the shell 10 and to avoid restricting the position of the clothes drying rod 20.

[0040] Further, referring to Figures 2, 5, and 6, the limiting structure 13 includes two spaced-apart limiting ribs 132, which form a limiting groove 131. The spacing between the two limiting ribs 132 near the groove is greater than the spacing away from the groove. In some embodiments, the two limiting ribs 132 have opposing inclined surfaces 1321. These inclined surfaces 1321 serve as guides, guiding the clothesline 20 from the groove to the limiting groove 131. Furthermore, these inclined surfaces 1321 ensure that the spacing between the two limiting ribs 132 near the groove is greater than the spacing away from the groove, allowing the limiting groove 131 to simultaneously serve as a limiter and a heat insulator.

[0041] In one embodiment, referring to FIG. 1 to FIG. 4 , the clothes drying rod 20 is provided with a plurality of air outlets 23 spaced apart along its length. In the unfolded state, the angle between the air outlet direction of the air outlet 23 and the direction of gravity is less than 90 degrees.

[0042] The clothesline 20 is provided with multiple air outlets 23 spaced along its length, ensuring uniform heating of multiple pieces of clothing hung on the clothesline 20. It will be appreciated that when clothes are hung on the clothesline 20, they are typically located below the clothesline 20. If the angle between the air outlets 23 and the direction of gravity is equal to 90 degrees, air is discharged from the side of the clothesline 20, preventing the hot air from reaching the clothes below the clothesline 20. If the angle between the air outlets 23 and the direction of gravity is greater than 90 degrees, the air is discharged upward. Hot air has a low density and is relatively light. After being discharged from the air outlets 23, hot air rises, preventing the clothes below the clothesline 20 from being heated. Furthermore, rising hot air poses a risk of burning the user's skin. In this embodiment, the angle between the air outlets 23 and the direction of gravity is less than 90 degrees. This ensures that the hot air fully contacts the clothes, improving drying efficiency and reducing heat loss.

[0043] In some embodiments, a hanging ring 54 is provided between the air outlets 23 spaced apart along the length direction of the clothes drying rod 20. In this way, clothes hangers with strong thermal conductivity or not resistant to high temperature can be hung on the clothes drying rod 20 from the hanging ring 54.

[0044] In one embodiment, please refer to Figures 1 and 5, the drying bracket also includes a support assembly 40 that is sleeved on the outer surface of the shell 10 and a limit adjustment member 50 that is movably connected to the support assembly 40; the limit adjustment member 50 includes a locking state and an active state; in the locking state, the limit adjustment member 50 locks the support assembly 40 relative to the shell 10; in the active state, the support assembly 40 can move relative to the outer surface of the shell 10 along the direction of gravity.

[0045] Because clothes vary in weight and the number of clothes to be hung can vary, hanging clothes on clothesline 20 can easily cause the drying rack 100 to tip over. The support assembly 40 improves the stability of the drying rack 100 and prevents it from tipping over. The position adjustment member 50 adjusts the height of the support assembly 40 relative to the ground and secures the support assembly 40 in a desired position. In some embodiments, the position adjustment member 50 is a position screw 52, ​​which can be switched between a locked state and an active state by turning the position adjustment member 50.

[0046] The coordination of the position adjustment member 50 and the support assembly 40 not only adjusts the overall height of the drying rack 100, making it easier for users to dry longer items such as long skirts or trousers, but also facilitates the movement of the drying rack 100. For example, the position adjustment member 50 can move the support assembly 40 to a distance from the bottom surface. This prevents the support assembly 40 from breaking when dragging or moving the drying rack 100. In some embodiments, the support assembly 40 is adjusted so that both the support assembly 40 and the bottom surface of the housing 10 are in contact with the ground. This lowers the center of gravity of the drying rack 100 and improves its stability.

[0047] Further, referring to Figure 1, the support assembly 40 includes an annular body 41 mounted on the shell 10 and a plurality of support legs 42 arranged at intervals along the circumference of the annular body 41. The support legs 42 are rotatably connected to the annular body 41 so as to be able to open and close relative to the shell 10.

[0048] The support legs 42 are rotatably connected to the annular body 41, making the use of the drying rack 100 more flexible. When the support legs 42 are opened relative to the shell 10, the overall stability of the drying rack 100 can be improved, preventing the drying rack 100 from tipping over when clothes are hung. When the support legs 42 are folded up, the floor space occupied by the drying rack 100 when it is idle can be reduced, making it easier for users to store it. In some embodiments, universal wheels 51 are provided at the bottom of the drying rack 100. When the user wants to move the drying rack, the support legs 42 can be folded up and spaced apart from the ground. Combined with the outward-facing wheels, the user can save effort when moving the drying rack 100 and avoid the support legs 42 from breaking or scratching the ground during movement.

[0049] Further, referring to Figures 1, 7, and 8, housing 10 includes a base 14, an air duct 15, a heater 16, and a fan 17. Base 14 is connected to the lower end of air duct 15, and heater 16 and fan 17 are located within base 14. In the stowed state, clothes drying rod 20 is stored within air duct 15. The connection of base 14 to the lower end of air duct 15 and the location of heater 16 and fan 17 within base 14 lower the center of gravity of drying rack 100, improving its stability and preventing it from tipping over when hanging clothes.

[0050] In certain embodiments, referring to Figures 1, 7, and 8, air inlet holes 53 are provided on the peripheral wall of the base 14 to facilitate the absorption of external air by the drying rack 100. In certain embodiments, referring to Figure 7, the heating element 16 is located above the fan 17. In this case, the fan 17 functions to diffuse the hot air and increase the flow rate of the hot air within the air guide 15. In certain embodiments, referring to Figure 8, the heating element 16 is located below the fan 17. In this case, the fan 17 functions to increase the flow rate of the cold air within the base 14, continuously blowing cold air to the heating element 16.

[0051] In certain embodiments, referring to Figures 2, 7, and 8, the support leg 42 includes a support body 421 and a support attachment 422. The support body 421 is hingedly connected to the annular body, while the support attachment 422 is hingedly connected to both the support body 421 and the base 14. This hinged connection facilitates the opening and closing of the support leg 42, preventing the support leg 42 from being lost during opening or closing. The support attachment 422 prevents the support body 421 from rotating relative to the annular body if the hinged connection between the support body 421 and the annular body becomes loose, thereby maintaining the stability of the drying rack 100.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
