Description

Technical Field

[0001] This application relates to the field of drying equipment technology, and in particular to dryer housings, dryers and drying systems. Background Technology

[0002] Currently, the development of clothes dryers in the industry can be roughly divided into two generations. The first generation is the separate dryer, in which the main unit and the wardrobe are independent. The wardrobe is a modular cabinet composed of several pipes, supporting components, clothes covers, etc. The main unit is a small hot air outlet. When working, the main unit is placed under the wardrobe, and the hot air from the main unit blows into the wardrobe to dry the clothes. However, the installation and disassembly steps of this type of separate dryer wardrobe are cumbersome and inconvenient for users. If it is not disassembled and placed indoors, it occupies living space and affects life. If it is disassembled, the wardrobe has a large number of parts and the clothes rod is long, which takes up a lot of storage space.

[0003] To address the inconvenience of installation and disassembly, as well as the space-consuming issues, foldable dryers were developed, leading to the second generation of dryers. The second generation is the box-type dryer, which uses the body as a wardrobe support and features an integrated telescopic clothes rod, replacing many of the original accessories. This significantly reduces the installation steps, making installation and disassembly extremely simple. Furthermore, when folded up, it resembles a suitcase, making it easy to store.

[0004] However, this box-type dryer has a small drying capacity, which cannot meet the needs of consumers to dry a lot of clothes at once. If the drying capacity is increased simply by increasing the volume of the box, the overall size of the machine will take up more space after storage, making it inconvenient to store. Summary of the Invention

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In some embodiments, please refer to Figures 1 to 7 A clothes dryer housing 10 is provided for mounting a fan assembly 20 and a heating element 30. The clothes dryer housing 10 includes a first outer shell assembly 11, a second outer shell assembly 12, and an air duct assembly 16. The second outer shell assembly 12 is rotatably connected to the first outer shell assembly 11, and the second outer shell assembly 12 and the first outer shell assembly 11 are configured to overlap or unfold each other. The air duct assembly 16 is disposed on the first outer shell assembly 11 and / or the second outer shell assembly 12, and is used to exhaust the airflow heated by the heating element 30 to the outside of the clothes dryer housing 10.

[0056] The aforementioned dryer casing 10 is designed with a first outer shell assembly 11 and a second outer shell assembly 12, which are rotatably connected. During drying, the first outer shell assembly 11 and the second outer shell assembly 12 can be rotated open, and hot air is vented out of the dryer casing 10 using the air duct assembly 16 to achieve effective drying. Since the unfolded dryer casing 10 nearly doubles the overall area, it effectively increases the drying capacity, achieving a large-capacity drying effect and meeting consumers' needs for drying multiple clothes at once. Simultaneously, during storage, the first outer shell assembly 11 and the second outer shell assembly 12 can be rotated and folded together, effectively reducing the volume of the dryer casing 10 and facilitating its storage. This design effectively satisfies both storage and drying needs simultaneously.

[0057] It should be noted that the first outer shell assembly 11 and the second outer shell assembly 12 are rotatably connected, allowing them to be folded or unfolded by rotation. During the drying process, the first outer shell assembly 11 and the second outer shell assembly 12 can be rotatably unfolded; then, the garment cover 200 is placed over the unfolded dryer housing 10 to perform the drying operation. Because the first outer shell assembly 11 and the second outer shell assembly 12 are unfolded, the space below the garment cover 200 can be expanded, thereby increasing the drying capacity. The garment cover 200 is a device used in conjunction with the dryer housing 10, covering the unfolded dryer housing 10 to form a closed environment, allowing the hot air blown out to dry the clothes inside the garment cover 200.

[0058] There are several ways to connect the first outer shell assembly 11 and the second outer shell assembly 12. For example, the first outer shell assembly 11 and the second outer shell assembly 12 can be directly hinged together. In this case, the first outer shell assembly 11 and the second outer shell assembly 12 need to be able to unfold or overlap when hinged. For example, the hinge position should be as close as possible to the edge of the first outer shell assembly 11 and the second outer shell assembly 12. Alternatively, the first outer shell assembly 11 and the second outer shell assembly 12 can be rotatably connected by a connecting rod. Or, a cylindrical structure that can rotate between the first outer shell assembly 11 and the second outer shell assembly 12 can be provided.

[0059] The number of second outer shell components 12 can be one or two. For example, two second outer shell components 12 are rotatably connected to opposite sides of the first outer shell component 11, so that the second outer shell components 12 on both sides can be stacked on the first outer shell component 11 when stored.

[0060] It should also be noted that the air duct assembly 16 can be disposed on either the first outer casing assembly 11 or the second outer casing assembly 12; of course, the air duct assembly 16 can be disposed on both the first outer casing assembly 11 and the second outer casing assembly 12, so that hot air can be emitted from both the first outer casing assembly 11 and the second outer casing assembly 12 during drying. The number of air duct assemblies 16 can be one, in which case the dryer 100 has a single air duct structure, as can be seen from [reference needed]. Figures 1 to 5 The number of air duct components 16 can also be multiple, such as two. This dryer 100 has a dual air duct structure, which can be referenced. Figures 6 to 8 .

[0061] Meanwhile, the installation position of the fan assembly 20 can be varied. For example, it can be installed on the first housing assembly 11 and connected to the air duct assembly 16 on the first housing assembly 11, so that the airflow enters the air duct assembly 16; or, it can be installed on the second housing assembly 12 and connected to the air duct assembly 16 on the second housing assembly 12; or, it can be installed between the first housing assembly 11 and the second housing assembly 12, in which case the fan assembly 20 can be connected to both the air duct assembly 16 on the first housing assembly 11 and the air duct assembly 16 on the second housing assembly 12.

[0062] In addition, the heating element 30 refers to a heat source that provides heat for heating the airflow, such as an electric heating device. The heating element 30 can be installed on the air duct assembly 16 or at the air outlet of the fan assembly 20, etc.

[0063] Further, please refer to Figure 3 and Figure 8The dryer housing 10 also includes a first mating assembly 13 connected to the first outer shell assembly 11 and a second mating assembly 14 connected to the second outer shell assembly 12. The first mating assembly 13 and the second mating assembly 14 are rotatably connected, and at least one of the first mating assembly 13 and the second mating assembly 14 has a first chamber 132 for mounting the impeller 22 of the fan assembly 20. The air duct assembly 16 communicates with the impeller 22 in the first chamber 132. Thus, the first mating assembly 13 and the second mating assembly 14 make it easier for the first outer shell assembly 11 and the second outer shell assembly 12 to rotate, fold, or unfold, facilitating drying and storage operations. At the same time, the first chamber 132 is provided in the first mating assembly 13 and / or the second mating assembly 14 to facilitate the airflow blown out by the impeller 22 into the air duct assembly 16, thereby facilitating the outward delivery of hot air.

[0064] It should be noted that when both the first mating component 13 and the second mating component 14 have a first chamber 132, it indicates that the fan assembly 20 of this embodiment has at least two impellers 22. At this time, a corresponding number of air duct assemblies 16 can be configured to increase the air outlet range.

[0065] The air duct assembly 16 is connected to the impeller 22 of the first chamber 132. This can be achieved in various ways, such as: the air duct assembly 16 is connected to the first chamber 132, using the first chamber 132 to achieve communication with the impeller 22; or, a portion of the air duct assembly 16 is located within the first chamber 132, and the impeller 22 can be housed within the air duct assembly 16. For details, please refer to [reference needed]. Figure 9 .

[0066] In addition, to ensure smooth rotation of the first housing assembly 11 and the second housing assembly 12, the air duct assembly 16 is preferably connected to the impeller 22 in the first chamber 132 located on the same housing assembly. For example, the air duct assembly 16 on the first housing assembly 11 is connected to the impeller 22 in the first chamber 132 on the first mating assembly 13; the air duct assembly 16 on the second housing assembly 12 is connected to the impeller 22 in the first chamber 132 on the second mating assembly 14.

[0067] Of course, in some other embodiments, if the air duct assembly 16 communicates with the impeller 22 located in the first chamber 132 on a different housing assembly, the air duct assembly 16 may also be connected to the first chamber 132 via a flexible hose, etc. It should be noted that the above housing assembly may include the first housing assembly 11 and the second housing assembly 12.

[0068] In some embodiments, please refer to Figure 8The first mating assembly 13 includes a first housing 131 having an axis 136, and the second mating assembly 14 includes a second housing 141. The second housing 141 is located on one side of the first housing 131 along the axis 136, and both are rotatable about the axis 136. At least one of the first housing 131 and the second housing 141 has a first chamber 132. Therefore, in the rotational design, the first housing 131 is located on one side of the second housing 141 along the axis 136, which not only facilitates the rotation of the first housing 131 and the second housing 141 about the axis 136, but also facilitates a tight connection between the first housing assembly 11 and the second housing assembly 12.

[0069] It should be noted that at least one of the first shell 131 and the second shell 141 is provided with a first chamber 132. For example, when the first shell 131 has a first chamber 132, the air duct assembly 16 can be provided on the first outer shell assembly 11 to maintain airflow communication with the impeller 22 in the first chamber 132; when the second shell 141 has a first chamber 132, the air duct assembly 16 can be provided on the second outer shell assembly 12; when both the first shell 131 and the second shell 141 have a first chamber 132, the air duct assembly 16 can be provided on the first outer shell assembly 11 and the second outer shell assembly 12 respectively. In this case, the motor 21 of the fan assembly 20 can be provided together with one of the impellers 22 in a first chamber 132.

[0070] In the first housing 131 and the second housing 141, one of them may be provided with a first chamber 132 and the other with a second chamber 142 for mounting the motor 21 of the fan assembly 20. This facilitates the connection of the motor 21 with the impeller 22 along the axis 136 and drives the impeller 22 to rotate around the axis 136.

[0071] For specific embodiments, please refer to Figure 3 and Figure 13 , Figure 3 This is an exploded view of the structure of a single-duct dryer in some embodiments of this application; Figure 13 This is a cross-sectional view of the unfolded dual-duct dryer described in some embodiments of this application. Figure 2 In the first housing 131 and the second housing 141, one has a first chamber 132, and the other has a second chamber 142 for mounting the motor 21 of the fan assembly 20. Of course, in other embodiments, a single-duct dryer 100 will be used as an example for illustration; please refer to [reference needed]. Figure 5 The impeller 22 and motor 21 of the fan assembly 20 are both installed in the first chamber 132 of the first housing 131.

[0072] Furthermore, the rotatable connection between the first shell 131 and the second shell 141 can be achieved through a shaft hole and shaft fit, or through a bearing, etc. Additionally, to facilitate smoother rotation of the first shell 131 and the second shell 141, both can be designed as cylindrical. Of course, in other embodiments, the shapes of the first shell 131 and the second shell 141 can also be other shapes.

[0073] Further, please refer to Figures 10 to 13 Both the first shell 131 and the second shell 141 have through holes 133 on their respective facing sides. One of the shells has a raised ring 143 surrounding its own through hole 133. The side of the raised ring 143 facing away from the axis 136 has a rotating groove 144. The raised ring 143 passes through the through hole 133 of the other shell, and the rotating groove 144 engages with the wall of the through hole 133. Therefore, during assembly, the raised ring 143 can be inserted into the through hole 133, placing it within either the first shell 131 or the second shell 141. Because the wall of the through hole 133 engages with the rotating groove 144, the interlocking structure between the rotating groove 144 and the wall of the through hole 133 prevents the first shell 131 and the second shell 141 from separating along the axis 136, thus achieving their connection.

[0074] Meanwhile, the wall of the perforation 133 is engaged in the rotating groove 144. Therefore, when the first shell 131 and the second shell 141 rotate relative to each other, the rotating groove 144 can move circumferentially along the perforation 133, which can guide the rotation of the first shell 131 and the second shell 141 and improve the smoothness of rotation.

[0075] To ensure a more stable connection between the first shell 131 and the second shell 141, the rotating groove 144 extends around the outer periphery of the axis 136 on the raised ring 143 to form an annular groove structure.

[0076] It should be noted that the rotating groove 144 refers to a concave or nearly concave structure on the raised ring 143, which allows the wall of the through hole 133 to be inserted. In the design, the rotating groove 144 can be grooved on the side of the raised ring 143 facing away from the axis 136 to form an annular groove structure; alternatively, a raised structure can be provided on the side of the raised ring 143 facing away from the axis 136, forming the rotating groove 144 between the raised structure and the first shell 131 or the second shell 141. Furthermore, to ensure smooth rotation, the through hole 133 for the raised ring 143 to pass through can be designed as a circular hole.

[0077] It should also be noted that both the first shell 131 and the second shell 141 are provided with through holes 133, so that the output shaft of the motor 21 on the fan assembly 20 can pass through the two through holes 133 in sequence and connect to the impeller 22 located in the first chamber 132.

[0078] Furthermore, please refer to Figure 12 and Figure 14 The protruding ring 143 includes a support portion 14c, a rim 14d, and a folded edge 14e. The support portion 14c is disposed around the outer periphery of the through hole 133, and the rim 14d is disposed on the support portion 14c and extends along the side opposite to the axis 136. A rotating groove 144 is formed between the rim 14d, the support portion 14c, and the first shell 131 or the second shell 141. The folded edge 14e protrudes from the side of the rim 14d facing the rotating groove 144. Thus, when the protruding ring 143 is inserted into the through hole 133, the wall of the through hole 133 is confined between the rim 14d and the first shell 131 or the second shell 141, realizing the connection between the first shell 131 and the second shell 141 in the direction of the axis 136. Since the folded edge 14e is positioned so that the early edge 14d faces the rotating groove 144, the folded edge 14e can abut against the inner wall of the first shell 131 or the second shell 141 during rotation. This replaces the contact between surfaces, reduces the friction area, and reduces the influence of friction on rotation, making the rotation between the first shell 131 and the second shell 141 smoother.

[0079] It should be noted that the edging 14d is provided on the support 14c and extends radially along the first shell 131. The edging 14d can be designed as a ring structure, such as being arranged in a ring around the outer periphery of the axis 136; or it can be designed as a non-ring structure, such as a protrusion, an arc plate, etc.

[0080] The folded edge 14e can be fixed to the edge 14d by combination methods, such as bolt connection, welding, or bonding; it can also be connected to the edge 14d by an integral molding method, such as bending one end of the edge 14d towards the rotating groove 144 to form the folded edge 14e.

[0081] In addition, the folded edge 14e can be in the form of a ring structure on the edge 14d, such as the folded edge 14e being arranged in a ring around the outer periphery of the axis 136; it can also be in the form of a convex hull or a protrusion.

[0082] In some embodiments, please refer to Figure 13 and Figure 14 The inner wall of the first shell 131 or the second shell 141, which has a through hole 133 that engages with the rotating groove 144, has a movable gap D in the axial direction 136 between it and the flange 14e. Thus, the movable gap D between the flange 14e and the inner wall of the first shell 131 or the second shell 141 ensures small-area contact movement between the two, thereby reducing rotational friction and ensuring smoother rotation.

[0083] It should be noted that the movable gap D allows for a certain degree of looseness in the direction of the folded edge 14e and the axis 136, but the movable gap D should not be designed to be too large to avoid the problem of the first housing assembly 11 and the second housing assembly 12 shaking due to the movable gap D being too large.

[0084] Therefore, the movement gap D can be between 0.1mm and 1.5mm. For example, the movement gap D can be, but is not limited to, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.8mm, 1mm, 1.2mm, and 1.5mm; specifically, the movement gap D can be 0.3mm. This can prevent wobbling caused by an excessively large movement gap D while also providing a good feel for rotation.

[0085] For specific embodiments, please refer to Figure 10 , Figure 12 and Figure 14 The first shell 131 includes an annular shell 13c with an axis 136, and a surrounding edge 13d and a supporting edge 13e located at both ends of the annular shell 13c along the axis 136. A first chamber 132 is formed between the surrounding edge 13d, the supporting edge 13e, and the annular shell 13c. The surrounding edge 13d is closer to the second shell 141 than the supporting edge 13e. A through hole 133 is provided on the surrounding edge 13d, and a protruding ring 143 is provided on the second shell 141. At this time, the rotating groove 144 on the protruding ring 143 is engaged with the through hole 133 on the surrounding edge 13d, and there is a movable gap D between the folded edge 14e and the surrounding edge 13d. Meanwhile, the second shell 141 has a second chamber 142 for mounting the motor 21 of the fan assembly 20.

[0086] In some embodiments, please refer to Figure 11 and Figure 14 In the through hole 133 that fits into the rotating groove 144, a first abutting protrusion 134 is provided on the hole wall of the through hole 133. The first abutting protrusion 134 is used to abut against the groove wall of the rotating groove 144. In this way, during rotation, it can replace the whole surface contact friction, reduce the contact area, reduce rotational friction, and further improve the smoothness of rotation.

[0087] It should be noted that the first abutting protrusion 134 can protrude along the axis 136 or radially along the through hole 133. When the first abutting protrusion 134 protrudes along the axis 136, it can abut against the side wall of the rotating groove 144; when the first abutting protrusion 134 protrudes radially, it can abut against the bottom wall of the rotating groove 144.

[0088] The rotating groove 144 has a bottom wall and a side wall. In some other embodiments, the protruding ring 143 includes a support portion 14c and a rim 14d. The support portion 14c is disposed on the outer wall of the first shell 131 or the second shell 141, and the rotating groove 144 is formed between the rim 14d, the support portion 14c, and the first shell 131 or the second shell 141. In this case, the side wall refers to the side of the rim 14d and the first shell 131 or the second shell 141 facing the rotating groove 144, and the bottom wall refers to the side of the support portion 14c facing the rotating groove 144.

[0089] In some embodiments, please refer to Figure 11 and Figure 14 On the two facing sides of the first shell 131 and the second shell 141, one side is provided with a second abutting protrusion 135 around the outer periphery of the axis 136, which abuts against the other side. In this way, the introduction of the second abutting protrusion 135 replaces the surface-to-surface contact between the first shell 131 and the second shell 141, reducing the friction area, reducing rotational friction, and thus further improving the smoothness of rotation.

[0090] It should be noted that the number of second abutment protrusions 135 can be one or more. When there are multiple second abutment protrusions 135, they can all be provided on the first shell 131 or the second shell 141; or some can be provided on the first shell 131 and the other part can be provided on the second shell 141.

[0091] In some embodiments, please refer to Figures 10 to 13 The second mating assembly 14 also includes a support member 145, which is located on both sides of the first shell 131 along the axis 136, and is rotatably connected to the first shell 131. Thus, by positioning the support member 145 and the second shell 141 on opposite sides of the first shell 131, the first shell assembly 11 and the second shell assembly 12 are more tightly joined; at the same time, the rotation between them is also smoother.

[0092] It should be noted that the rotational connection between the support member 145 and the first shell 131 can be a shaft and shaft hole fit, or a bearing connection, etc. Furthermore, the number of support members 145 can be one or multiple. For example, when there are two first shells 131, the second shell 141 is located between the two first shells 131, and each support member 145 is located on the side of the corresponding first shell 131 facing away from the second shell 141.

[0093] To facilitate gas flow into the first chamber 132, the support member 145 can be designed with a hollow structure. For example, the support member 145 has several through holes 14f, allowing airflow to be drawn into the first chamber 132 through the through holes 14f. In addition, to prevent the fan assembly 20 from sucking in impurities, the dryer housing 10 may also include a grille 15. The side of the support member 145 facing away from the first housing 131 has a mounting groove 14g, and the grille 15 is installed in the mounting groove 14g.

[0094] In some embodiments, please refer to Figure 10 , Figure 12 and Figure 13In the first shell 131 and the support member 145, one is provided with a rotating hole 137, and the other is provided with a limiting member 146, forming a groove 147 around the outer periphery of the axis 136. The limiting member 146 passes through the rotating hole 137, and the wall of the rotating hole 137 is engaged in the groove 147. Thus, by inserting the limiting member 146 into the rotating hole 137, the wall of the rotating hole 137 is engaged in the groove 147. This not only achieves axial limiting, but also guides the rotation between the support member 145 and the first shell 131 through the cooperation between the groove 147 and the rotating hole 137, improving the smoothness of rotation.

[0095] It should be noted that the connection method of the limiting member 146 on the first shell 131 or the support member 145 can be various, such as, but not limited to, bolt connection, snap-fit, adhesive, welding, pin connection, etc.

[0096] For specific embodiments, please refer to Figure 12 and Figure 16 A limiting member 146 is provided on the side of the support member 145 facing the first shell 131, and an annular groove 147 is formed between the support member 145 and the limiting member 146. Meanwhile, the first shell 131 includes an annular shell 13c with an axis 136, and a surrounding edge 13d and a supporting edge 13e provided at both ends of the annular shell 13c along the axis 136. The supporting edge 13e is disposed close to the support member 145 relative to the surrounding edge 13d, and a rotating hole 137 is provided on the supporting edge 13e.

[0097] In some embodiments, please refer to Figure 8 The first shell 131 and the air duct assembly 16 each include two or more. All the first shells 131 are spaced apart along the axis 136, and a second shell 141 is rotatably connected between two adjacent first shells 131. Each first shell 131 has a first chamber 132, and each air duct assembly 16 is disposed on the first outer shell assembly 11. It can be seen that the dryer box 10 of this embodiment has a multi-air duct structure, that is, multiple first shells 131 are introduced, so that multiple impellers 22 can be correspondingly distributed in the first chambers 132, thereby helping to expand the air outlet range.

[0098] Meanwhile, each air duct component 16 is located within the first outer shell component 11, and both the first outer shell component 16 and the first outer shell component 131 of the first outer shell component 11 are equipped with impellers 22. Therefore, the center of gravity of the dryer casing 10 is more biased towards one side of the first outer shell component 11, resulting in a weight difference in the entire machine. At this time, the first outer shell component 11 is more stable, while the second outer shell component 12 is lighter. This allows the machine to be unfolded or folded by rotating the second outer shell component 12, facilitating one-handed operation and improving convenience.

[0099] In some embodiments, please refer to Figure 8 , Figure 10and Figure 15 The first housing 131 includes a first upper housing 13a and a first lower housing 13b, both of which are connected to the first outer housing assembly 11, and the first upper housing 13a and the first lower housing 13b are detachably connected. Thus, designing the first housing 131 as the first upper housing 13a and the first lower housing 13b along the thickness direction X of the dryer housing 10 facilitates the assembly and disassembly of the dryer housing 10.

[0100] Optionally, the connection between the first upper shell 13a and the first lower shell 13b can be, but is not limited to, bolt connection, snap-fit, pin connection, magnetic engagement, etc.

[0101] It should be noted that the first upper shell 13a and the first lower shell 13b refer to the two parts of the first shell 131 in the thickness direction X of the dryer housing 10. When the first shell 131 has a first chamber 132, the first upper shell 13a and the first lower shell 13b can be enclosed to form the first chamber 132.

[0102] In addition, in the above embodiments, the first shell 131 may include an annular shell 13c having an axis 136, and a surrounding edge 13d and a supporting edge 13e disposed at both ends of the annular shell 13c along the axis 136. The annular shell 13c, the surrounding edge 13d, and the supporting edge 13e are respectively constituent structures of the first shell 131 along the axis 136. The first upper shell 13a and the first lower shell 13b are respectively constituent structures of the first shell 131 along the thickness direction X. The first upper shell 13a includes a portion of the annular shell 13c, the surrounding edge 13d, and the supporting edge 13e respectively in the thickness direction X; the first lower shell 13b includes another portion of the annular shell 13c, the surrounding edge 13d, and the supporting edge 13e respectively in the thickness direction X.

[0103] In some embodiments, please refer to Figure 8 , Figure 12 and Figure 16 The second shell 141 includes a second upper shell 14a and a second lower shell 14b, both of which are connected to the second outer shell assembly 12, and are detachably connected. Thus, designing the second shell 141 as a second upper shell 14a and a second lower shell 14b along the thickness direction X of the dryer housing 10 facilitates the assembly and disassembly of the dryer housing 10.

[0104] Optionally, the connection between the second upper shell 14a and the second lower shell 14b can be, but is not limited to, bolt connection, snap-fit, pin connection, magnetic engagement, etc.

[0105] It should be noted that the second upper shell 14a and the second lower shell 14b refer to the two parts of the second shell 141 in the thickness direction X of the dryer housing 10. When the second shell 141 has a second chamber 142, the second upper shell 14a and the second lower shell 14b can be closed to form the second chamber 142.

[0106] In some embodiments, please refer to Figure 9 and Figure 17 The first housing assembly 11 and / or the second housing assembly 12 have a receiving cavity 113 communicating with the first chamber 132 and an outlet 114 communicating with the receiving cavity 113. The air duct assembly 16 is located within the receiving cavity 113 and partially extends into the first chamber 132. The portion of the air duct assembly 16 located within the first chamber 132 is used to install the impeller 22. Therefore, placing the air duct assembly 16 within the receiving cavity 113 facilitates its concealment, ensuring a cleaner appearance for the dryer housing 10. It also facilitates the protection of the air duct assembly 16.

[0107] Further, please refer to Figure 9 and Figure 17 The air duct assembly 16 includes a volute 161 and an air guide 162 communicating with the volute 161. The volute 161 is located in the first chamber 132 and is used to install the impeller 22. The air guide 162 is located in the receiving cavity 113, and one end of it extends into the outlet 114. Thus, during drying, the airflow blown by the impeller 22 enters the air guide 162 from the volute 161 and then exits from the outlet 114.

[0108] The heating element 30 can be disposed inside the air guide body 162, so that the airflow entering the air guide body 162 can be heated by the heating element 30. At the same time, one end of the air guide body 162 can extend into the outlet 114, but not extend out of the outlet 114; or it can extend out of the outlet 114.

[0109] It should be noted that during the drying process, when the impeller 22 rotates, it will draw in cold air from both sides of the impeller 22. After being squeezed by the impeller 22 and the volute 161, and then guided by the guide body 162, the air with a certain air volume will be blown out and will generate warm air after passing through the heating element.

[0110] In some embodiments, please refer to Figure 8 Both the first outer shell assembly 11 and the second outer shell assembly 12 include an outer shell 112 and an inner shell 111 disposed within the outer shell 112. In the first outer shell assembly 11 and the second outer shell assembly 12, at least one of them forms a receiving cavity 113 between the outer shell 112 and the inner shell 111. It can be seen that both the first outer shell assembly 11 and the second outer shell assembly 12 are designed as two-part structures, which makes assembly more convenient.

[0111] Optionally, the outer shell 112 and the inner shell 111 can be connected in a detachable manner, such as by bolt connection, snap-fit, pin connection, etc.

[0112] Additionally, the first shell 131 includes a first upper shell 13a and a first lower shell 13b along the thickness direction X of the dryer housing 10, and the second shell 141 includes a second upper shell 14a and a second lower shell 14b along the thickness direction X of the dryer housing 10. The first upper shell 13a is connected to the inner shell 111 of the first outer shell assembly 11, and the first lower shell 13b is connected to the outer shell 112 of the first outer shell assembly 11. The second upper shell 14a is connected to the inner shell 111 of the second outer shell assembly 12, and the second lower shell 14b is connected to the outer shell 112 of the second outer shell assembly 12.

[0113] Specifically, the first upper shell 13a and the inner shell 111 of the first outer shell assembly 11 are an integral structure, and the first lower shell 13b and the outer shell 112 of the first outer shell assembly 11 are an integral structure. The second upper shell 14a and the inner shell 111 of the second outer shell assembly 12 are an integral structure, and the second lower shell 14b and the outer shell 112 of the second outer shell assembly 12 are an integral structure.

[0114] In some specific embodiments, please refer to Figure 18 Taking the dual-duct dryer housing 10 as an example, during the assembly of the whole machine, firstly, place the outer shell 112 of the first outer shell assembly 11 on a flat surface, and then similarly lay down the outer shell 112 of the second outer shell assembly 12 to assemble it with the outer shell 112 of the first outer shell assembly 11. During the lowering process, the protruding ring 143 of the second shell 141 extends into the through hole 133 of the first shell 131, and the limiting piece 146 on the support member 145 on both sides of the second shell 141 extends into the rotating hole 137 of the first shell 131, and the slot 147 is locked onto the hole wall of the rotating hole 137. At this time, the first lower shell 13b of the first shell 131 and the second lower shell 14b of the second shell 141 are assembled. Then, the motor 21 of the fan assembly 20 is fixedly installed on the second lower shell. In step 14b, the air duct assembly 16 is fixedly installed on the outer shell 112 of the first outer shell assembly 11, at which time the impeller 22 is located inside the volute 161 of the air duct assembly 16; finally, the inner shell 111 of the second outer shell assembly 12 is fixedly installed on the outer shell 112 of the second outer shell assembly 12, and the inner shell 111 of the first outer shell assembly 11 is fixedly installed on the outer shell 112 of the first outer shell assembly 11. At this time, the first shell 131 on the first outer shell assembly 11 and the second shell 141 on the second outer shell assembly 12 both form a complete circular perimeter 13d structure, and each is an independent whole. The circular circumferential engagement of the first shell 131 and the second shell 141 realizes that the two components can rotate around the cylindrical axis, with a rotation range of 0°~180°.

[0115] In some embodiments, please refer to Figure 5 and Figure 8 A clothes dryer 100 includes: a fan assembly 20, a heating element 30, and a dryer housing 10 as described above. The fan assembly 20 is provided in one of the first housing assembly 11, the second housing assembly 12, and between the first housing assembly 11 and the second housing assembly 12. The fan assembly 20 is used to supply air into an air duct assembly 16. The heating element 30 is disposed in the air duct assembly 16 and is used to heat the airflow in the air duct assembly 16.

[0116] The aforementioned dryer 100 utilizes a dryer housing 10, designed with a first outer shell assembly 11 and a second outer shell assembly 12, which are rotatably connected. During drying, the first outer shell assembly 11 and the second outer shell assembly 12 can be rotated open, and hot air is vented out of the dryer housing 10 via the air duct assembly 16, achieving an effective drying effect. Since the unfolded dryer housing 10 nearly doubles the overall area of ​​the machine, it effectively increases the drying capacity, achieving a large-capacity drying effect and meeting consumers' needs for drying multiple clothes at once. Simultaneously, during storage, the first outer shell assembly 11 and the second outer shell assembly 12 can be rotated and folded together, effectively reducing the volume of the dryer housing 10 and facilitating its storage. This design effectively satisfies both storage and drying needs simultaneously.

[0117] It should be noted that the dryer 100 has an unfolded state and a retracted state. When the first outer shell assembly 11 and the second outer shell assembly 12 are rotated and overlapped to present an angle of approximately 0°, the dryer 100 is in the retracted state; when the first outer shell assembly 11 and the second outer shell assembly 12 are rotated and unfolded to present an angle of approximately 180°, the dryer 100 is in the unfolded state.

[0118] In some embodiments, the fan assembly 20 includes a motor 21 and a fan wheel 22 driven to rotate by the motor 21, with the fan wheel 22 located within the air duct assembly 16. Thus, by placing the fan wheel 22 within the air duct assembly 16, the airflow can be stably introduced into the air duct assembly 16 when the motor 21 drives the fan wheel 22 to rotate, achieving a stable drying effect.

[0119] It should be noted that the motor 21 can be a single-shaft structure, which can be connected to the impeller 22 located on one side of the motor 21; or it can be a dual-shaft structure, in which case the motor 21 can be connected to the impellers 22 located on both sides of itself. See the reference for details. Figure 19Furthermore, when motor 21 has a single-shaft structure, the end connecting the output shaft of motor 21 to the impeller 22 can be extended, allowing both ends of motor 21 to be effectively supported. For example, both ends of motor 21 can be supported on the two support members 145 of the second mating assembly 14, making the rotation of motor 21 more stable and efficient. Simultaneously, the length of impeller 22 can vary with the width of the entire unit. Because both ends of motor 21 are supported, there will be no abnormal swaying. Therefore, even with an extended impeller 22, rotation will still be stable, and the overall airflow will not be affected. Moreover, changing to a single air duct will reduce overall material costs, improve installation efficiency, and allow for a wider range of adjustable unit size.

[0120] In some embodiments, please refer to Figure 1 and Figure 6 A clothes drying system, comprising the above-mentioned dryer 100.

[0121] The aforementioned drying system utilizes a drying unit 10, designed with a first outer shell assembly 11 and a second outer shell assembly 12, which are rotatably connected. During drying, the first outer shell assembly 11 and the second outer shell assembly 12 can be rotated open, allowing hot air to be expelled from the drying unit 10 via the air duct assembly 16, achieving effective drying. Since the expanded drying unit 10 nearly doubles the overall area, it effectively increases the drying capacity, achieving a large-capacity drying effect and meeting consumers' needs for drying multiple clothes at once. Simultaneously, during storage, the first outer shell assembly 11 and the second outer shell assembly 12 can be rotated and folded together, effectively reducing the volume of the drying unit 10 and facilitating its storage. This design effectively satisfies both storage and drying requirements simultaneously.

[0122] The drying system may also include a garment cover 200, which is positioned above the dryer 100.

[0123] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0124] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
