[0037] A clothes dryer is a device used to dry wet clothes. It speeds up the drying process by placing clothes inside the machine, heating the air, and expelling the moisture through an exhaust vent. Clothes dryers typically have multiple drying modes that can be selected based on the fabric type and individual needs.

[0038] Compared to lingerie dryers, clothes dryers are generally larger and suitable for drying various types and sizes of clothing. Clothes dryers typically have higher drying temperatures and larger capacities, allowing them to handle more clothes at once. Using a clothes dryer can save time and labor, making it especially suitable for large families or situations requiring frequent laundry.

[0039] Clothes dryers are typically large, stationary appliances that don't usually need to be folded for storage, thus taking up considerable space when not in use. This necessitates foldable dryers. However, existing foldable dryers are relatively complicated to operate, and require manual power-off after folding, compromising safety.

[0040] Therefore, this invention proposes a portable roll-up clothes drying device, which aims to achieve convenient use and quick folding and storage of the clothes drying device while ensuring the safe operation of the clothes drying device.

Figure 1 ; Figure 11 The portable roll dryer heater of the present invention is in use. Figure 2 ; Figure 12 This is a diagram showing the portable roll-to-roll clothes dryer of the present invention in its stored state.

[0042] In this embodiment of the invention, the portable roll dryer includes a heater 10, a control switch 16, a pull rod 13, and a drying bag 20; as Figure 1-12 As shown, the heater 10 includes a housing 11, a roller rotatably mounted inside the housing 11, a storage space for winding a clothes drying bag 20 between the roller and the housing 11, and a heating element 12 mounted inside the roller. The housing 11 has an air inlet 113 and an air outlet 111. In this embodiment, the air outlet 111 is located on the outer periphery of the housing 11, the air inlet 113 is located on the side of the housing 11 and on both sides of the air outlet 111, and the heating element 12 can rotate with the roller to allow air to flow from its outlet end. Facing the air outlet 111, a control switch 16 is located inside the housing 11. The control switch 16 is used to control the power supply to or off of the heating element 12. A pull rod 13 is telescopically mounted on the roller. When the pull rod 13 is in the extended state, it is used to operate the control switch 16 to control the power supply to the heating element 12. One end of the drying bag 20 extends from the air outlet 111 into the housing 11 and is connected to the roller. The drying bag 20 has a stored state that is wound around the roller and an unfolded state that is unfolded relative to the roller.

[0043] Specifically, in this embodiment, when the clothes drying bag 20 is detachably installed to the air outlet 111, the pull rod 13 can be inserted into the clothes drying bag 20 for hanging clothes and drying them. When storing the clothes drying bag 20, one end of the clothes drying bag 20 can be wrapped around the pull rod 13, the roller can be rotated, and the clothes drying bag 20 can be tightened so that the clothes drying bag 20 is inserted into the storage space inside the housing 11 and wound around the roller for storage.

[0044] The technical solution of this invention uses a freely rollable drying bag 20 as the drying chamber of the drying device. When drying clothes, the drying bag 20 is detachably installed on the air outlet 111 of the heater 10, and warm air is blown into the drying bag 20. When storing the drying device, the drying bag 20 is rolled up on the roller inside the heater 10, realizing convenient use and quick storage of the drying device. A retractable pull rod 13 is set up to link with the drying and storage operations. When drying, the pull rod 13 is pulled out to be used as a clothes rack, and the control switch 16 is pressed at the same time to power on the heater element 12. When rolling up for storage, the pull rod 13 is retracted into the housing 11 and away from the control switch 16, so that the heater element 12 is de-energized, realizing the safe use of this portable roller-type drying device.

[0045] Furthermore, the clothes drying bag 20 is provided with an air outlet 23 and an air inlet 21 for communicating with the air outlet 111, in conjunction with reference to... Figure 2 , Figure 3 As shown, in this embodiment, the air outlet 23 can be located at the bottom of the clothes drying bag 20. There are multiple air outlets 23 distributed in a dot matrix. The outer periphery of the air inlet 21 is provided with a detachable connecting part 22. The detachable connecting part 22 is used to detachably install the clothes drying bag 20 to the air outlet 111. In this embodiment, the detachable connecting part 22 is a Velcro strip surrounding the air inlet 21. The Velcro strip is attached to the inner wall of the housing 11 through the air outlet 111, so that the clothes drying bag 20 is installed on the heater 10 and the air inlet 21 is connected to the air outlet 111 of the heater 10.

[0046] In another embodiment, the detachable connection 22 is a magnetic adhesive strip surrounding the air inlet 21. The inner wall of the housing 11 is provided with a corresponding magnetic material. The magnetic adhesive strip is attracted to the magnetic material through the air outlet 111, allowing the clothes dryer bag 20 to be installed on the heater 10 and connecting the air inlet 21 with the air outlet 111 of the heater 10. Alternatively, the detachable connection 22 can also be a spring-loaded fastener structure.

[0047] Preferably, the pull rod 13 includes two parallel cantilever portions 132, a hanging rod portion 130 located at the end of the cantilever portion 132 away from the reel, and a positioning slider 133 located at the end of the cantilever portion 132 near the reel, in conjunction with reference to... Figure 5 , Figure 6As shown, the hanging rod 130 connects two cantilever parts 132. The cantilever parts 132 are slidably installed inside the scroll by the positioning slider 133. In this embodiment, two grooves for limiting the sliding of the positioning slider 133 are respectively opened at both ends of the outer shell of the scroll. The positioning slider 133 is slidably installed in the groove, so that the cantilever part 132 slides relative to the scroll.

[0048] Specifically, when the pull rod 13 is pulled out, the hanging rod part 130 at the end of the pull rod 13 away from the roller can be used to hang clothes on a clothes rack. When the clothes drying bag 20 is installed on the heater 10, the hanging rod part 130 extends into the clothes drying bag 20, making it convenient to arrange clothes in the clothes drying bag 20.

[0049] Preferably, the control switch 16 is provided with a downwardly pressable elastic sheet, in conjunction with a reference. Figure 5 As shown, a pressing part 134 is provided on one side of a positioning slider 133, and an elastic sheet is located directly below the pressing part 134. The pressing part 134 is used to press the elastic sheet as the positioning slider 133 slides to control the power supply of the heating element 12.

[0050] Specifically, the pressing part 134 will press against the elastic plate of the control switch 16 only after the lever 13 is pulled out to the full position. Only when the elastic plate is pressed can the control switch 16 control the heating element 12 to be powered on. Therefore, when the lever 13 is not fully pulled down or is stored in the housing 11, the drying device cannot be powered on and used, so that the drying device cannot be powered on when not in use, thereby ensuring the operational safety of the drying device.

[0051] In addition, a locking structure is provided inside the scroll. When the pull rod 13 is pulled out to the end, the locking structure locks the pull rod 13 to prevent the pressing part 134 from shifting and causing the elastic plate to reset, which would cause the control switch 16 to control the heating element 12 to cut off the power. Specifically, the locking structure can be an elastic protrusion. When the pull rod 13 is pulled out to the end, the elastic protrusion deforms and presses against the positioning slider 133 to limit the pull rod 13. When the pull rod 13 is retracted, the pull rod 13 can be pushed towards the scroll to separate the positioning slider 133 from the elastic protrusion. The positioning slider 133 can slide freely, allowing the pull rod 13 to be retracted into the housing 11.

[0052] Furthermore, in conjunction with reference Figure 5 As shown, the upper end face of the hanging rod 130 is provided with a plurality of spaced-apart limiting grooves 131. In this embodiment, the upper end face of the hanging rod 130 is provided with a silicone or rubber anti-slip pad, and the limiting grooves 131 are formed on the anti-slip pad. Specifically, when a clothes hanger is hung on the hanging rod 130, the limiting grooves 131 can limit the clothes hanger, so that the clothes hung on adjacent clothes hangers maintain a certain distance, thereby ensuring ventilation when drying clothes.

[0053] Preferably, the heating element 12 includes a plurality of fans 120 arranged side by side along the axial direction of the spool and a heating element 121 disposed below the air outlet of the fans 120, in conjunction with reference to [reference needed]. Figure 7 As shown, the heating element 121 extends along the arrangement direction of the multiple fans 120. In this embodiment, the heating element 121 is a PTC resistance heater, and three fans 120 are selected and distributed at equal intervals.

[0054] Specifically, by setting up multiple fans 120 side by side to simultaneously blow air onto the heating element 121, the air heated by the heating element 121 is blown out more evenly, forming uniform hot air, thereby improving the efficiency of drying clothes.

[0055] Furthermore, it also includes an anti-slip part 110 disposed on the housing 11, in conjunction with reference to... Figure 4 , Figure 10 As shown, the anti-slip part 110 extends along the axial direction of the roll and is disposed on both sides of the air outlet 111. In this embodiment, the anti-slip part 110 is composed of multiple adjacent concave and convex textures formed on the outer surface of the housing 11. When the clothes drying bag 20 is separated from the housing 11 and the pull rod 13 extends out of the air outlet 111, the anti-slip part 110 and the hanging rod part 130 are respectively used to form two support points for the heating fan 10 to be placed horizontally along the axial direction.

[0056] Specifically, when the clothes drying bag 20 is separated from the heater 10, the heater 10 can be used independently. At this time, the pull rod 13 is pulled out from the housing 11, and the pressing part 134 presses the control switch 16 to control the heating element 12 to be powered on. The heater 10 is placed horizontally along the axis, with the anti-slip part 110 and the hanging rod part 130 of the extended pull rod 13 serving as two support points, so that the air outlet 111 of the heater 10 is tilted downwards and limited, thereby allowing the heater 10 to be used independently for heating.

[0057] Furthermore, it also includes a support plate 15 disposed on the housing 11, the support plate 15 being disposed away from the air outlet 111, in conjunction with reference to... Figure 4 , Figure 11 As shown, when the clothes drying bag 20 is disassembled from the housing 11, the support plate 15 and the anti-slip part 110 are respectively used to form support points for the two heating fans 10 to be placed horizontally along the axial direction.

[0058] Specifically, when the clothes drying bag 20 is separated from the heater 10, the pull rod 13 can be pulled out from the housing 11, and the pressing part 134 can press the control switch 16 to control the heating element 12 to be powered on. The heater 10 is then placed horizontally along the axis, with the anti-slip part 110 and the support plate 15 serving as two support points, so that the air outlet 111 of the heater 10 is tilted towards the upper limit, thereby allowing the heater 10 to be used alone for heating.

[0059] In this embodiment, there are two support plates 15, which are symmetrically arranged facing away from the air outlet 111. The two support plates 15 correspond to two anti-slip parts 110 respectively, so that the heater 10 can be placed in a limited position by the anti-slip parts 110 and the support plates 15 regardless of whether the air outlet 111 is facing left or right.

[0060] In addition, the two support plates 15 can provide two support points for the heater 10 when the air outlet 111 is placed with the opening facing upwards, so that the air outlet 111 can open upwards to deliver air.

[0061] Furthermore, it also includes a hook 14 disposed on the housing 11, in conjunction with reference to... Figure 8 , Figure 9 As shown, the hook 14 includes a straight rod portion 141 and a hanging portion 140. The housing 11 has a storage groove 112 on the side away from the air outlet 111. The straight rod portion 141 can be stored in the storage groove 112. One end of the straight rod portion 141 is rotatably mounted in the storage groove 112, and the other end of the straight rod portion 141 is connected to the hanging portion 140.

[0062] Specifically, when the heater 10 is equipped with the drying bag 20 and used as a drying device, the hook 14 can be rotated out of the storage slot 112 to make the straight rod 141 stand upright, and the heater 10 can be suspended to store clothes in the drying bag 20. When the heater 10 is in the storage state, the hook 14 can be flipped over and stored in the storage slot 112.

[0063] Furthermore, it also includes a knob 17 located on one side of the housing 11 and coaxially arranged with the spool, in conjunction with reference to [reference needed]. Figure 4 As shown, the knob 17 passes through the housing 11 and is fixedly connected to the roller. Specifically, when the dryer bag 20 is rolled up and stored on the roller, the roller can be rotated by operating the knob 17 located on one side of the housing 11, thereby rolling up and storing the dryer bag 20.

[0064] The technical solution of this invention uses a detachable drying bag 20 as the drying chamber of the drying device. When drying clothes, the drying bag 20 is installed at the air outlet 111 of the heater 10, and warm air is blown into the drying bag 20. When storing the drying device, the drying bag 20 is rolled up on the roller inside the heater 10, realizing convenient use and quick folding and storage of the drying device. A retractable pull rod 13 is set to link with the drying and storage operations. When drying, the pull rod 13 is pulled out and the control switch 16 is pressed to power on the heater element 12 and start it. When storing, the pull rod 13 is retracted into the housing 11 and away from the control switch 16 to de-power the heater element 12, realizing the safe use of this portable roller-type drying device.

[0065] In addition, the anti-slip part 110 and support plate 15 provided on the housing 11 cooperate with the pull rod 13 for support, so that the heater 10 can be placed independently and used as a separate heating device, thereby improving the practicality of the clothes drying device.

[0066] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
