Description

Technical Field

[0001] The invention relates to the technical field of dryers, and in particular to a foldable dryer. Background Art

[0002] Dryers, as machines for drying clothes, have gradually become a necessity in people's lives. As a market segment, foldable portable dryers bring greater convenience to people. However, the folding structure design of existing foldable portable dryers is unreasonable, which makes folding difficult and often requires the cooperation of both hands.

[0003] CN202010014944.X discloses a split-type foldable portable clothes dryer, whose folding function is realized by a foldable bracket, which includes a plurality of rods connected in sequence, two adjacent rods are hinged by a hinge, and the hinge is composed of two side plates, the two rods are hinged to the same side plate, and the other side plate plays a positioning role for the unfolded folding bracket. The disadvantage of this hinge method is that the middle shelf needs to be disassembled to fold the folding bracket, which is cumbersome and inconvenient to operate; the side plate of the hinge only plays a limiting role in preventing the folding bracket from rotating and folding outward, and does not play a role in stabilizing the folding bracket in the unfolded state. If there is no middle shelf, a little external force will easily cause the folding bracket to rotate inward and collapse, which is not convenient for normal use. Summary of the invention

[0004] In order to overcome at least one of the defects of the prior art described above, the present invention provides a foldable drying machine.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A foldable dryer comprises a base assembly, an upper cover assembly, a clothes drying cover and at least two sets of hinge assemblies, wherein the base assembly is provided with a main assembly for providing hot air, and the clothes drying cover is connected between the base assembly and the upper cover assembly to form a drying chamber for accommodating clothes, wherein the hinge assembly comprises two hinges rotatably connected to each other, the upper cover assembly and the base assembly are respectively provided with hinge seats rotatably matched with the hinges, and the hinge seats are provided with first positioning grooves; when the hinge assembly is unfolded, the two hinges are respectively embedded in and positioned in the first positioning grooves of the two hinge seats.

[0007] Furthermore, the hinge is in an elastic U-shape, comprising a cross bar and two vertical bars connected to the two ends of the cross bar, the ends of the two vertical bars are respectively provided with rotating shafts, and the hinge seat is provided with an axial hole matching the rotating shaft; when the hinge assembly is unfolded, the ends of the vertical bars are embedded and positioned in the first positioning groove under the elastic force of the hinge.

[0008] Furthermore, a first bevel surface for guiding the vertical rod to rotate and slide into the first positioning groove is provided on one side wall of the first positioning groove.

[0009] Furthermore, the hinge seat is also provided with a second positioning groove for limiting the vertical rod in the folded position, the second positioning groove is arranged at an angle to the first positioning groove, and a second bevel surface for guiding the vertical rod to rotate and slide into the second positioning groove is provided on one side wall of the second positioning groove.

[0010] Furthermore, the first positioning groove is located on the outer side of the U-shape of the hinge, and when the two vertical rods are compressed toward the inner side of the U-shape of the hinge, the vertical rods are separated from the first positioning groove.

[0011] Furthermore, a baffle is also provided on the hinge seat; when the hinge is elastically deformed so that the vertical rod is separated from the first positioning groove, the baffle is used to limit the rotation shaft from being separated from the shaft hole.

[0012] Furthermore, the two hinges are U-shaped with different sizes, and the cross bars of the two hinges are rotatably connected through an intermediate hinge; when the hinge assembly is folded, the relatively small hinge rotates around the relatively large hinge through the intermediate hinge and is retracted on the inner side of the relatively large hinge.

[0013] Further, one end of the intermediate hinge is fixed to the hinge of relatively small size, and the other end of the intermediate hinge is hinged to the hinge of relatively large size.

[0014] Furthermore, the clothes drying cover is arranged on the outside of the hinge assembly, and the upper and lower ends of the clothes drying cover are detachably connected to the base assembly and the upper cover assembly respectively.

[0015] Furthermore, the host assembly is detachably arranged on the base assembly.

[0016] In summary, the drying machine provided by the present invention has the following technical effects:

[0017] The dryer can be folded and opened by the hinge assembly, and the hinge is positioned by the first positioning groove of the hinge seat in the unfolded state to stabilize the hinge assembly in the unfolded state and prevent it from collapsing. When folding is required, the hinge can be driven out of the first positioning groove by external force to release the positioning, and the folding operation can be achieved. Other beneficial effects of the present invention will be shown in the specific implementation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0046] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] Example 1

[0049] See also Figures 1 to 8 The present invention discloses a drying machine, comprising a base assembly 1, an upper cover assembly 2, a clothes drying cover 3 and a support assembly. The base assembly 1 is provided with a host assembly 7 for providing hot air, preferably, the host assembly 7 is detachably provided on the base assembly 1; the support assembly is connected between the base assembly 1 and the upper cover assembly 2 to prop open the upper cover assembly 2; the clothes drying cover 3 is connected between the base assembly 1 and the upper cover assembly 2 to form a drying chamber for accommodating clothes.

[0050] Among them, the supporting assembly is at least two groups of hinge assemblies 4, and the two ends of the hinge assembly 4 are respectively hinged to the base assembly 1 and the upper cover assembly 2. The upper cover assembly 2 can be supported by the hinge assembly 4, so that the clothes drying cover 3 forms a drying chamber for accommodating clothes between the base assembly 1 and the upper cover assembly 2; at the same time, the upper cover assembly 2 can be covered on the base assembly 1 through the hinge assembly 4 to complete the folding of the dryer for easy carrying and storage.

[0051] The clothes drying cover 3 is disposed on the outside of the hinge assembly 4, and the upper and lower ends of the clothes drying cover 3 are detachably connected to the base assembly 1 and the upper cover assembly 2, respectively. Preferably, the clothes drying cover 3 is a flexible cloth cover 31 for easy storage and cleaning. Of course, the clothes drying cover 3 can also be made of other flexible materials.

[0052] Among them, the base component 1 includes a bottom shell 11 with a cavity 118, and the main host component 7 is detachably arranged on the bottom shell 11. The main host component 7 outputs hot air to the cavity 118 of the bottom shell 11, and the hot air is then output to the drying cavity through the cavity 118 of the bottom shell 11; the upper cover component 2 includes an upper shell 21 and a flip cover 22 connected to the upper shell 21, and the clothes can be placed in the drying cavity through the flip cover 22.

[0053] In this embodiment, the hinge assembly 4 includes two hinges 41 rotatably connected to each other, and the upper cover assembly 2 and the base assembly 1 are respectively provided with a hinge seat 5 rotatably matched with the hinge 41, and the hinge seat 5 is provided with a first positioning groove 51; when the hinge assembly 4 is unfolded, the two hinges 41 are respectively embedded in and positioned in the first positioning grooves 51 of the two hinge seats 5.

[0054] The hinge seat 5 is arranged on the inner side of the bottom shell 11 of the base assembly 1 or the inner side of the upper shell 21 of the upper cover assembly 2 .

[0055] Thus, the dryer can be folded and opened through the hinge assembly 4, and the hinge 41 in the unfolded state is positioned by the first positioning groove 51 of the hinge seat 5 to stabilize the unfolded state of the hinge assembly 4 and prevent it from collapsing. When folding is required, the hinge 41 can be driven out of the first positioning groove 51 by external force to release the positioning, thereby realizing the folding operation.

[0056] See also Figures 2 to 6 Specifically, the hinge 41 is in an elastic U-shape, and includes a horizontal bar 411 and two vertical bars 412 connected to the two ends of the horizontal bar 411. The ends of the two vertical bars 412 are respectively provided with a rotating shaft 413, and the hinge seat 5 is provided with a first shaft hole 53 matched with the rotating shaft 413; when the hinge assembly 4 is unfolded, the ends of the vertical bars 412 are embedded and positioned on the first positioning groove 51 under the elastic force of the hinge 41. Through the above structure, when unfolding, the elastic force of the U-shaped hinge 41 is used to drive its vertical bars 412 to be embedded and positioned in the first positioning groove 51, so as to realize the positioning of the hinge 41 by the hinge seat 5; when folding, only external force is needed to drive the U-shaped hinge 41 to elastically deform so that its vertical bars 412 are separated from the first positioning groove 51 to release the positioning, making the folding operation easier and faster, and the structure is simple and the production cost is low.

[0057] See also Figure 3 and Figure 4 Preferably, a first bevel surface 511 for guiding the vertical rod 412 to rotate and slide into the first positioning groove 51 is provided on a side wall of the first positioning groove 51 .

[0058] Due to the shape characteristics of the first beveled surface 511 and the elastic force of the hinge 41 itself, in the process of unfolding the dryer, when the two hinges 41 are unfolded to a certain angle so that the vertical rod 412 enters the first beveled surface 511, the vertical rod 412 can slide along the first beveled surface 511 under the elastic force of the hinge 41 until the vertical rod 412 is embedded in the first positioning groove 51. At this time, the vertical rod 412 is limited by the other side wall of the first positioning groove 51 and the wall surface of the first beveled surface 511, and the opening of the dryer is completed. When folding, it is only necessary to apply a force toward the middle of the dryer on the hinge assembly 4, and the two hinges 41 rotate relative to each other and fold inward. During the folding process, under the guidance of the first bevel surface 511, the rotating shaft 413 of the hinge 41 rotates in the shaft hole 53 and produces axial displacement, and the vertical rod 412 gradually opens or compresses the hinge 41 until the vertical rod 412 is released from the first bevel surface 511 and the limit is released, and the upper cover assembly can be further pressed down until it is covered on the base assembly 1, and the dryer is folded. One person can complete the opening and folding operations, which is simple and convenient; and compared with the method of setting up a hinge in the prior art, this structure has fewer parts, a simpler structure, and a more stable support.

[0059] See also Figure 3 and Figure 4 In this embodiment, the hinge seat 5 is further provided with a second positioning groove 52 for limiting the vertical rod 412 in the folded position. The second positioning groove 52 is arranged at an angle with the first positioning groove 51, and a second bevel surface 521 for guiding the vertical rod 412 to rotate and slide into the second positioning groove 52 is provided on one side wall of the second positioning groove 52. The principle of the second positioning groove 52 and the second bevel surface 521 is consistent with the principle of the first positioning groove 51 and the first bevel surface 511, and the action process thereof will not be described in detail here. Therefore, the second bevel surface 521 can make the folded state of the dryer more stable.

[0060] Indeed, since the second positioning groove 52 and the second bevel surface 521 are used for the folding of the dryer, only the wall surface of the second bevel surface 521 is required to limit the vertical rod 412 on one side, and the second positioning groove 52 is not required to clamp and limit the vertical rod 412 on both sides. Therefore, the second positioning groove 52 may not have another side wall to save materials.

[0061] In this embodiment, preferably, the first positioning groove 51 is located outside the U-shaped shape of the hinge 41, and when the two vertical rods 412 are compressed toward the inside of the U-shaped shape of the hinge 41, the vertical rods 412 are separated from the first positioning groove 51. Therefore, the elastic force of the hinge 41 acts in the direction of driving the two vertical rods 412 to open relatively outwards, and when removing the hinge 41, the two vertical rods 412 can be grasped with one hand and compressed inwards to make the rotating shaft 413 separate from the shaft hole 53, thereby taking out the hinge 41, which is convenient for its removal.

[0062] Of course, in another preferred embodiment, the first positioning groove 51 may also be located inside the U-shaped hinge 41. At this time, the elastic force of the hinge 41 acts in a direction to drive the two vertical rods 412 to shrink inwardly relative to each other.

[0063] In this embodiment, a baffle 54 is further provided on the hinge seat 5; when the hinge 41 is elastically deformed to allow the vertical rod 412 to disengage from the first positioning groove 51, the baffle 54 is used to limit the rotation shaft 413 from disengaging from the shaft hole 53. Thus, the problem that the hinge 41 generates elastic bounce when too much force is applied during folding, causing the rotation shaft 413 to disengage from the shaft hole 53, can be avoided.

[0064] See also Figure 5 , Figure 7 and Figure 8 In this embodiment, the two hinges 41 are in two U-shaped shapes of different sizes, and the crossbars 411 of the two hinges 41 are connected by a middle hinge 42 to realize rotation; when the hinge assembly 4 is folded, the hinge 41 of relatively small size rotates around the hinge 41 of relatively large size through the middle hinge 42 and is folded inside the hinge 41 of relatively large size. Therefore, by using the middle hinge 42 and combining the size limit of the two hinges 41, the hinge assembly 4 occupies less space when folded, which facilitates the dryer to be thinner when folded.

[0065] Preferably, one end of the intermediate hinge 42 is fixed to the relatively small hinge 41, and the other end of the intermediate hinge 42 is hinged to the relatively large hinge 41. Thus, when in the open state, the hinge assembly 4 does not generate excessive degrees of freedom, and the deviation of the two hinges 41 at the connection with the intermediate hinge 42 is avoided.

[0066] It should be noted that the specific shapes of the hinge seat 5 installed on the base assembly 1 and the hinge seat 5 installed on the upper cover assembly 2 can be different, and the specific shapes and sizes of the components of the two hinge seats 5 can also be different, as long as the same working principle and effect are achieved.

[0067] Example 2

[0068] See also Figures 9 to 15 The difference between this embodiment and implementation 1 is that the dryer disclosed in this embodiment specifically discloses a specific structure in which the cloth cover 31 is detachably connected between the base assembly 1 and the upper cover assembly 2.

[0069] The dryer provided in this embodiment includes the base assembly 1, the upper cover assembly 2, the cloth cover 31 and the support assembly as described in Embodiment 1.

[0070] In this embodiment, buckle edges 32 are provided at the upper and lower ends of the cloth cover 31, and slots 6 are provided on the base assembly 1 and the upper cover assembly 2. The slots 6 are provided with buckle portions 61 that snap-fit ​​with the buckle edges 32. Through the relative cooperation between the buckle edges 32 and the buckle portions 61, the cloth cover 31 can be detachably connected between the base assembly 1 and the upper cover assembly 2.

[0071] The card slot 6 located at the base assembly 1 is arranged on the inner side of the bottom shell 11 of the base assembly 1 ; the card slot 6 located at the upper cover assembly 2 is arranged on the inner side of the upper shell 21 of the upper cover assembly 2 .

[0072] Through the above structure, when the cloth cover 31 is dirty, the cloth cover 31 can be disassembled and cleaned separately, so as to facilitate daily maintenance and cleaning of the cloth cover 31, and the cloth cover 31 can also be replaced to save use costs.

[0073] See also Figures 13 to 15 Specifically, the slot 6 includes an elastic side wall 62 that can be elastically deformed, the buckle portion 61 is arranged on the elastic side wall 62, and one side of the buckle edge 32 is provided with a convex rib 321 that cooperates with the buckle portion 61; when the buckle edge 32 is inserted into the slot 6, the convex rib 321 of the buckle edge 32 presses against the buckle portion 61 to drive the elastic side wall 62 to elastically deform so that the buckle edge 32 can be inserted into and confined on the slot 6.

[0074] Among them, in the slot 6 located in the base assembly 1, its elastic side wall 62 is connected to the bottom shell 11, and the elastic side wall 62 and the inner wall of the bottom shell 11 are structured to form the slot 6; in the slot 6 located in the upper cover assembly 2, its elastic side wall 62 is connected to the upper shell 21, and the elastic side wall 62 and the inner wall of the upper shell 21 are structured to form the slot 6.

[0075] Therefore, by utilizing the elastic deformation characteristics of the elastic side wall 62, the buckle portion 61 can limit the rib 321, which facilitates the fixation and removal of the buckle edge 32 in the slot 6, avoids wear and aging of the buckle portion 61 and the buckle edge 32 during repeated assembly and disassembly, and extends their service life.

[0076] See also Fig. 9 and Fig.13 Preferably, the slot 6 is a closed structure surrounded by a middle cavity, and the elastic side wall 62 is located inside the slot 6. The slot 6 can be a circular closed structure, an elliptical closed structure, a frame-shaped closed structure, etc. The specific shape of the slot 6 can be determined according to product design requirements. When the slot 6 is a frame-shaped closed structure, its corners can be rounded to prevent the elastic side wall 62 from being difficult to elastically deform at its corners.

[0077] Since the elastic side wall 62 is located on the inner side of the slot 6 and is connected end to end in a closed shape, during the repeated elastic deformation of the elastic side wall 62, the end of the elastic side wall 62 is squeezed and deformed inward as a whole. Therefore, the elasticity of the elastic side wall 62 is more stable and is not prone to deformation fatigue.

[0078] In this embodiment, in order to facilitate the buckle edge 32 to be inserted into or removed from the slot 6 , a first arc surface is provided on the convex rib 321 .

[0079] Preferably, a second arc surface is provided on the buckle portion 61 to further facilitate the buckle edge 32 to be inserted into or removed from the buckle slot 6 .

[0080] See also Fig.14 and Fig.15 In this embodiment, the slot 6 is further provided with a positioning rib 63 for limiting the buckle edge 32. In the slot 6 of the base assembly 1, the positioning rib 63 is connected between the elastic side wall 62 and the bottom shell 11; in the slot 6 of the upper cover assembly 2, the positioning rib 63 is connected between the elastic side wall 62 and the upper shell 21.

[0081] Therefore, the positioning rib 63 is used to limit the distance that the buckle edge 32 is inserted into the slot 6 , so as to prevent the buckle edge 32 from being too loose when being buckled, thereby facilitating the fixation of the cloth cover 31 .

[0082] Preferably, the hinge seat 5 is fixedly connected to the inner side wall of the slot 6, and the position of the hinge seat 5 corresponds to the positioning rib 63. The hinge seat 5 is stabilized by the positioning rib, and compared with the fixing method of separately setting the hinge seat 5 on the bottom shell 11 or the upper shell 21, the structure is simpler, so as to reduce the overall material weight of the dryer and save production costs.

[0083] Example 3

[0084] See also Figures 16 to 22 The difference between this embodiment and embodiment 1 or 2 is that the dryer disclosed in this embodiment specifically discloses a detachable host structure in which the host component 7 can be detachably installed on the base component 1.

[0085] In this embodiment, the detachable host structure includes a dryer body and the host assembly 1, and the dryer body includes a bottom shell. The dryer body includes the upper cover assembly 2, the base assembly 1, the support assembly and the clothes drying cover 3 as described in Embodiment 1 or 2, and the bottom shell of the dryer body is the bottom shell 11 of the base assembly 1.

[0086] In this embodiment, the bottom of the bottom shell 11 is provided with a mounting cavity 111 opening downward, and the side wall of the mounting cavity 111 is provided with a slider 112; the host assembly 7 includes a host shell 71, and the side wall of the host shell 71 is provided with an L-shaped groove 711 that slides with the slider 112. Through the relative cooperation between the slider 112 and the L-shaped groove 711, the host assembly 7 can be detachably mounted on the mounting cavity 111 of the bottom shell 11. Therefore, by utilizing the relative cooperation between the slider 112 and the L-shaped groove 711, the host assembly 7 can be detached from the base assembly 1, which is convenient for storage and carrying. At the same time, the host assembly 7 can be used alone as a heater and other purposes, meeting the user's demand for multi-functions and multi-purposes of the same product.

[0087] The L-shaped groove 711 includes a vertical groove section and a horizontal groove section that are interconnected. The upper end of the vertical groove section is open, and the sliding block 112 can enter the L-shaped groove 711 through the opening of the vertical groove section.

[0088] Specifically, at least two sliders 112 are disposed on two opposite side walls of the installation cavity 111, and L-shaped grooves 711 corresponding to the number of the sliders 112 are disposed on two opposite side walls of the main housing 71. Multiple groups of sliders 112 cooperate with the L-shaped grooves 711, so that the main assembly 7 can be installed more stably on the bottom housing 11.

[0089] See also Figures 19 to 22 Preferably, the top wall of the installation cavity 111 is provided with a locking protrusion 113, and the top of the main housing 71 is provided with a locking groove 712 that matches the locking protrusion 113; when the slider 112 slides to the preset position of the horizontal groove section of the L-shaped groove 711, the locking protrusion 113 and the locking groove 712 are engaged to position the main housing 71. Therefore, through the engagement of the locking protrusion 113 with the locking groove 712, when the main housing assembly 7 is installed, the main housing assembly 7 will not shake, and during the process of carrying, moving, and transporting, the main housing assembly 7 is not easily dropped from the bottom housing 11 and damaged by a slight external force.

[0090] In this embodiment, a pre-positioning groove 713 is further provided on the top of the main housing 71, and the pre-positioning groove 713 is located on one side of the slot 712; when the slider 112 slides to the intersection of the vertical slot section and the horizontal slot section of the L-shaped slot 711, the protrusion 113 is located on the pre-positioning groove 713. Through the cooperation between the pre-positioning groove 713 and the protrusion 113, it is possible to judge from the outside whether the slider 112 and the L-shaped slot 711 are in place when the main assembly 7 is installed. When the protrusion 113 is not in place, it will press against other positions of the main housing 71, and the main housing 71 will protrude outward to cause unevenness.

[0091] Preferably, the pre-positioning groove 713 is in the shape of an elongated strip, and the length direction of the pre-positioning groove 713 is consistent with the length direction of the transverse groove section of the L-shaped groove 711. The elongated pre-positioning groove 713 can better cooperate with the sliding of the slider 112 in the transverse groove section of the L-shaped groove 711.

[0096] Example 4

[0097] See also Figure 23 to Figure 25 The difference between this embodiment and embodiment 1, 2 or 3 is that the dryer disclosed in this embodiment specifically discloses an air duct structure applied to the dryer.

[0098] In this embodiment, the dryer includes a base assembly 1, an upper cover assembly 2, a support assembly, a drying cover 3 and a main unit assembly 7 as described in Embodiment 1, 2 or 3. The base assembly 1 also includes the bottom shell 11, and the main unit assembly 7 is arranged on the bottom shell 11.

[0099] In this embodiment, the cavity 118 of the bottom shell 11 is provided with an air guide 12 corresponding to the hot air outlet 714 of the main unit component 7, and the air guide 12 has at least two air guides 121 for diverting the hot air of the main unit component 7 to both sides of the cavity 118. Thus, the hot air outputted from the main unit component 7 is diverted to both sides of the cavity 118 by the air guide 12, so that the air outlet is smoother and more uniform.

[0100] Specifically, the mainframe assembly 7 is located in the middle of the bottom shell 11 so that hot air can be evenly distributed to both sides.

[0101] See also Fig.24 and Fig.25 In this embodiment, the bottom shell 11 is provided with an air outlet cover 13 for covering the cavity 118, and the air outlet cover 13 is provided with a plurality of air outlet holes 131. Hot air is output from the cavity 118 to the drying cavity through the air outlet holes 131 of the air outlet cover 13, and the air outlet is fine, and the clothes falling on the air outlet cover 13 will not affect the drying effect.

[0102] In this embodiment, the bottom shell 11 is further provided with a support platform 14 for supporting clothes at a position corresponding to the main unit assembly 7, and the support platform 14 is higher than the air outlet layer cover 13. Preferably, slopes 141 connected to the air guide duct 121 are respectively provided on both sides of the support platform 14, and a plurality of oblique holes 142 for air outlet are provided on the slope 141. Thus, through the structure of the slope 141 with the oblique holes 142, the hot air is discharged from the oblique holes 142 into the drying chamber, and the obliquely transported hot air is more conducive to drying the clothes at the corners.

[0103] See also Fig.23 In this embodiment, the air guide member 12 is located at the hot air inlet 114 of the installation cavity 111. Specifically, the air guide member 12 includes two connected arc-shaped air guide plates 122, and the two arc-shaped air guide plates 122 are combined with the bottom shell 11 to form two air guide channels 121 at the hot air inlet 114 of the installation cavity 111. When hot air enters the two air guide channels 121 from the hot air inlet 114, it will impact the two arc-shaped air guide plates 122. The arc shape of the arc-shaped air guide plates 122 can better guide the flow of hot air, maintain the wind speed of the hot air, and have less noise.

[0104] See also Fig.24 and Fig.25 In this embodiment, the upper cover assembly 2 is provided with a plurality of exhaust ports 211. Specifically, the exhaust ports 211 are provided on the periphery of the upper shell 21 of the upper cover assembly 2. Thus, the moisture and air in the drying chamber can be discharged outward from the exhaust ports 211.

[0105] See also Fig.25 In this embodiment, an intermediate shelf 8 for supporting clothes is further provided between the base assembly 1 and the upper cover assembly 2. Specifically, the intermediate shelf is provided between the two hinge assemblies 4. Through the intermediate shelf 8, clothes can be placed in the middle of the drying chamber, which can better facilitate the drying of clothes.
