[0037] Please see Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of the clothes drying equipment provided in this application; Figure 2 This is a three-dimensional structural diagram of the clothes drying equipment provided in this application after disassembly. Figure 3 This is a cross-sectional structural schematic diagram of an embodiment of the clothes drying device provided in this application. This application provides a clothes drying device 1000. The clothes drying device 1000 includes an inner drum 10, an outer drum 20, and a housing 80, wherein the inner drum 10 is a roller, and the outer drum 20 is a fixed drum. During the operation of the clothes drying device 1000, the outer drum 20 remains stationary, while the inner drum 10 can rotate relative to the outer drum 20. The inner drum 10 has a first cavity 10a. The outer drum 20 covers the outside of the inner drum 10 to form a second cavity 20a between the inner drum 10 and the outer drum 20. The housing 80 is disposed outside the outer drum 20 to form a third cavity 80a between the outer drum 20 and the housing 80. The inner cylinder 10 and the outer cylinder 20 are coaxially arranged and separated by a certain distance to avoid interference with the outer cylinder 20 when the inner cylinder 10 rotates radially and axially. The coaxial arrangement of the inner cylinder 10 and the outer cylinder 20 can reduce the volume of the outer cylinder 20, making the structure more compact, reducing production costs, and reducing structural weight.

[0038] The inner cylinder 10 forms a first cavity 10a, the inner cylinder 10 and the outer cylinder 20 form a second cavity 20a, and the outer cylinder 20 and the shell 80 form a third cavity 80a. The first cavity 10a is used to place the items to be dried. The second cavity 20a can serve as insulation to reduce the heat dissipation rate of the first cavity 10a, thereby reducing the energy consumption of the drying equipment 1000 and improving its energy efficiency. The third cavity 80a can be used to house components such as the evaporator 91, condenser 92, air supply component 93, compressor 94, throttling component 95, connecting pipes 96, and motor 97. The inner cylinder 10, outer cylinder 20, and shell 80 cooperate with each other, resulting in a compact structure.

[0039] When the drying equipment 1000 is working, the material to be dried is constantly turned over in the first cavity 10a under the rotation of the inner cylinder 10. The hot dry airflow exchanges heat fully with the material to be dried, so that the moisture of the material to be dried evaporates and is discharged with the hot dry airflow.

[0040] The inner cylinder 10 includes an inner cylinder side wall 11 and an inner cylinder bottom wall 12. The inner cylinder side wall 11 and the inner cylinder bottom wall 12 are fixedly connected or integrally formed, and the fixed connection method includes, but is not limited to, riveting, welding, and other connection methods. The inner cylinder side wall 11 surrounds the inner cylinder bottom wall 12 to form a first cavity 10a. The inner cylinder 10 also includes an open end 13 and a cylinder bottom end 14 arranged opposite to each other along the axial direction. The open end 13 of the inner cylinder 10 has a first opening 15, which can serve as an inlet and outlet for the items to be dried. The cylinder bottom end 14 is the inner cylinder bottom wall 12.

[0041] Please refer to the following: Figures 4 to 8 , Figure 4 This is a three-dimensional structural diagram of the clothes drying device provided in this application after omitting the housing; Figure 5 This is a three-dimensional structural schematic diagram of one embodiment of the inner and outer drums of the clothes drying device provided in this application; Figure 6 This is a three-dimensional structural schematic diagram of an embodiment of the motor and mounting part of the clothes drying device provided in this application; Figure 7 This is a three-dimensional structural schematic diagram of one embodiment of the motor and belt of the clothes drying device provided in this application; Figure 8 This is an exploded perspective view of one embodiment of the clothes drying device provided in this application. The outer tube 20 includes a mounting portion 40, which is located on the side of the outer tube 20 facing away from the inner tube 10. The mounting portion 40 has a receiving cavity 41, and the side of the receiving cavity 41 facing the opening end 13 or the bottom end 14 of the tube has a first through hole 42. The first through hole 42 may be formed on the side of the mounting portion 40 facing the opening end 13 or on the side of the mounting portion 40 facing the bottom end 14 of the tube. In some embodiments, the mounting portion 40 may also be formed on both the side of the mounting portion 40 facing the opening end 13 and the side of the mounting portion 40 facing the bottom end 14 of the tube.

[0042] The mounting part 40 can be integrally formed with the outer cylinder 20. This integral connection method ensures the structural strength of the mounting part 40. At the same time, in the manufacturing process of the drying equipment 1000, it reduces the types and number of parts, simplifies assembly, saves time, and improves assembly efficiency. Of course, the mounting part 40 can also be fixedly connected to the outer cylinder 20. Fixed connection methods include, but are not limited to, riveting, welding, bonding, bolting, keying, snap-fit, and magnetic adsorption.

[0043] The drying device 1000 also includes a motor 97 and a belt 98. The motor 97 has a motor body 971, a drive rod 972, and a drive wheel 973 connected in sequence. The motor body 971 is located outside the outer cylinder 20, the drive rod 972 passes through the first through hole 42, and the drive wheel 973 is disposed in the receiving cavity 41. The receiving cavity 41 communicates with the second cavity 20a. The belt 98 is sleeved on the drive wheel 973 and the inner cylinder 10. The motor 97 drives the inner cylinder 10 to rotate through the motor body 971, the drive rod 972, the drive wheel 973, and the belt 98. The belt 98 may have a certain elasticity, and the drive wheel 973 provides tension to the belt 98, thereby ensuring the tension between the inner cylinder 10 and the belt 98, and ensuring that the belt 98 can drive the inner cylinder 10 to rotate. In some embodiments, the drive wheel 973 may be omitted, and the belt 98 may be directly sleeved on the drive rod 972 and the inner cylinder 10.

[0044] By placing the motor body 971 outside the outer cylinder 20, the motor 97 can dissipate heat during operation of the drying equipment 1000, thus solving the technical problem of heat dissipation difficulties for the motor 97, improving the performance of the motor 97, and ensuring the service life of the drying equipment 1000. By providing a receiving cavity 41 and a first through hole 42 in the mounting part 40, and placing the drive wheel 973 in the receiving cavity 41, the installation problem of the belt 98 and drive wheel 973 is solved, facilitating the mounting of the belt 98 onto the drive wheel 973. Furthermore, interference between the drive rod 972 and drive wheel 973 and the outer cylinder 20 can be avoided during operation, thus protecting both the motor 97 and the outer cylinder 20.

[0045] The mounting section 40 also includes a first sealing element 43, which is disposed in the receiving cavity 41 and seals between the second cavity 20a and the receiving cavity 41. This seal isolates the second cavity 20a from the external environment, ensuring the airtightness of the outer cylinder 20. The first sealing element 43 is adapted to the receiving cavity 41, thereby ensuring its sealing effect and preventing airflow leakage from the second cavity 20a through the receiving cavity 41 and the through hole 42. This solves the installation problems of the motor 97 and the belt 98, as well as the sealing problem of the second cavity 20a.

[0046] The receiving cavity 41 has a side cavity wall 412 and a back cavity wall 411. The plane containing the back cavity wall 411 is perpendicular to the plane containing the side cavity wall 412, and the plane containing the back cavity wall 411 is perpendicular to the extension direction of the drive rod 972. The first seal 43 includes a main body portion 431 and a sealing portion 432. The sealing portion 432 is disposed circumferentially along the main body portion 431. The main body portion 431 can be used to support the sealing portion 432, preventing the sealing portion 432 from collapsing, thereby improving the sealing effect of the first seal 43. The thickness of the sealing portion 432 can be greater than the thickness of the main body portion 431, thereby further improving the sealing effect of the first seal 43. The side of the sealing part 432 away from the main body part 431 can be connected by adhesive bonding, snap-fit ​​connection, bolt connection or other connection methods, or by the rebound ability of the first sealing member 43 itself to seal the connection with the side cavity wall 412 of the receiving cavity 41, so as to ensure the sealing connection between the first sealing member 43 and the side cavity wall 412 of the receiving cavity 41, thereby isolating the receiving cavity 41 from the second cavity 20a and ensuring the sealing of the second cavity 20a.

[0047] The first seal 43 has a second through hole 43a, and at least one side of the second through hole 43a has a flange 433. The second through hole 43a can be located at the geometric center of the main body 431 of the first seal 43, or it can be located at other positions on the main body 431. The flange 433 can be located on the side of the main body 431 facing the motor 97, or on the side of the main body 431 away from the motor 97, or on both sides of the main body 431 facing the motor 97 and away from the motor 97. The flange 433 is integrally formed with the main body 431, thereby ensuring the structural strength of the flange 433, preventing the flange 433 from falling off, and reducing the number of parts and assembly steps, thus improving assembly efficiency.

[0048] The first sealing element 43 is a silicone seal, a rubber seal, a leather seal, or an acrylonitrile butadiene styrene (ABS) plastic seal. The first sealing element 43 is elastic; when it is positioned in the receiving cavity 41, the side wall 412 of the receiving cavity 41 applies stress to it, causing a certain deformation. This deformation provides contact pressure to the side wall 412, thereby achieving a seal.

[0049] The first seal 43 has a plurality of first reinforcing ribs 434. The plurality of first reinforcing ribs 434 are disposed on the side of the first seal 43 facing and / or away from the motor 97. Specifically, the first reinforcing ribs 434 are disposed on the main body portion 431 of the first seal 43. The first reinforcing ribs 434 can be disposed on the side of the main body portion 431 facing the motor 97, or on the side of the main body portion 431 away from the motor 97, or simultaneously on both sides. The provision of the first reinforcing ribs 434 can reduce the thickness of the first seal 43, thereby reducing the structural weight and space occupancy of the first seal 43, while ensuring the structural strength of the first seal 43.

[0050] The motor 97 also includes a connector 974, which is sleeved on the drive rod 972 and located between the drive wheel 973 and the motor body 971. The connector 974 can be a ring structure, with its inner ring tightly fitted onto the drive rod 972. In some embodiments, the connector 974 can be provided with an internal thread, and the drive rod 972 is provided with an external thread that mates with the internal thread of the connector 974. By providing both the external and internal threads, the connector 974 is fixed to the drive rod 972.

[0051] The connector 974 passes through the first through hole 42 and is engaged in the second through hole 43a and the flange 433 of the first seal 43, thereby restricting the drive wheel 973 and the belt 98 between the first seal 43 and the back cavity wall 411 to prevent the belt 98 from falling off during transmission and improve reliability.

[0052] The mounting portion 40 also includes a cover plate 44, which is detachably mounted on the side of the mounting portion 40 away from the motor body 971 to form a receiving cavity 41. In some embodiments, a first sealing member 43 is first disposed on the mounting portion 40, and then the drive rod 972 of the motor 97 is passed through the first through hole 42, the second through hole 43a and the flange 433 from the side of the mounting portion 40 with the first through hole 42 to the other side of the mounting portion 40. At the same time, a connector 974 is disposed in the second through hole 43a and the flange 433 of the first sealing member 43. Then, the drive wheel 973 is disposed at the end of the drive rod 972, and the belt 98 is sleeved on the drive wheel 973 and the inner cylinder 10. The cover plate 44 is then detachably mounted on the side of the mounting portion 40 away from the motor body 971. Finally, the sealing part 432 of the first sealing member 43 away from the main body 431 is sealed and connected to the side cavity wall 412 of the receiving cavity 41 by means of adhesive bonding, snap-fit ​​connection, bolt connection or other connection methods.

[0053] By setting the cover plate 44, the assembly of the first seal 43, the motor 97 and the belt 98 is facilitated, reducing labor time and thus improving assembly efficiency. At the same time, it facilitates the disassembly and maintenance of the first seal 43, the motor 97 and the belt 98, thereby improving maintenance efficiency.

[0054] The outer cylinder 20 has a relief groove 201, which is arranged circumferentially along the outer cylinder 20 and protrudes in a direction away from the inner cylinder 10. The relief groove 201 communicates with the receiving cavity 41. The relief groove 201 can have a certain depth to avoid the belt 98, preventing friction between the belt 98 and the outer cylinder 20, thereby reducing the rotational resistance of the inner cylinder 10 and improving the drying effect of the drying equipment 1000. The depth of the relief groove 201 can be less than 5mm, which can limit the volume of the outer cylinder 20 and prevent the belt 98 from deforming due to friction with the outer cylinder 20 and the belt 98 when rotating. The structure is compact and the structural weight is reduced.

[0055] The clearance groove 201 extends circumferentially around the outer cylinder 20, thereby further improving the structural strength of the outer cylinder 20, making the outer cylinder 20 less prone to heat deformation during the operation of the drying equipment 1000, and improving its service life.

[0056] The housing 80 includes a bottom housing 83, which is located at the bottom of the drying equipment 1000. The outer cylinder 20 includes a first cover plate 21, a second cover plate 22, and a bottom plate 23 connected sequentially in a circumferential direction. The bottom plate 23 is located on the side of the outer cylinder 20 facing the bottom housing 83. The mounting part 40 is located on the side of the first cover plate 21 or the second cover plate 22 facing the bottom plate 23. The motor body 971 is mounted on the bottom housing 83. Since the motor body 971 is heavy and large, mounting the motor body 971 on the bottom housing 83 solves the installation problem of the motor body 971.

[0057] The outer cylinder 20 is formed by splicing together the first cover plate 21, the second cover plate 22, and the base plate 23. During assembly, the assembly position of the base plate 23 can be determined in advance, and then the assembly position of the inner cylinder 10 can be determined based on the base plate 23. Other parts between the inner cylinder 10 and the outer cylinder 20 are then assembled. After the base plate 23 and the inner cylinder 10 are assembled, the first cover plate 21 is assembled to one side of the base plate 23, and the second cover plate 22 is assembled to the other side of the base plate 23. Finally, the side of the first cover plate 21 facing away from the base plate 23 is connected to the side of the second cover plate 22 facing away from the base plate 23. After the inner cylinder 10 and the outer cylinder 20 are assembled, the axial direction of the outer cylinder 20 can coincide with or be parallel to the axial direction of the inner cylinder 10, thereby improving assembly efficiency. Furthermore, it can prevent interference between the inner cylinder 10 and the outer cylinder 20 during assembly, which could lead to deformation. The outer cylinder 20 has a simple structure and small individual parts, facilitating component processing, overall assembly, and maintenance.

[0058] The first cover plate 21 and the second cover plate 22 can be arc-shaped. The surfaces of both the second cover plate 22 and the first cover plate 21 facing the inner cylinder 10 can be convex arc surfaces, protruding in a direction away from the inner cylinder 10. The bottom plate 23 can be arc-shaped, or it can be a flat plate. The first cover plate 21, the second cover plate 22, and the bottom plate 23 are relatively small in size, making them easy to process and shape, thus reducing production difficulty and costs.

[0059] The first cover plate 21, the second cover plate 22, and the bottom plate 23 all have mutually cooperating clearance grooves 201. The clearance grooves 201 are arranged circumferentially along the outer cylinder 20 and protrude in a direction away from the inner cylinder 10. The second cover plate 22 has a mounting part 40, which is located on the side of the second cover plate 22 away from the first cover plate 21, or on the side of the first cover plate 21 away from the second cover plate 22. The mounting part 40 has a receiving cavity 41, and the side of the receiving cavity 41 facing the opening end 13 or the bottom end 14 of the cylinder has a first through hole 42. The first through hole 42, the receiving cavity 41, and the clearance grooves 201 are connected.

[0060] The first cover plate 21, the second cover plate 22, and the bottom plate 23 each have a plurality of second reinforcing ribs 24, the extension direction of which may be parallel to the axial direction of the outer cylinder 20. The second reinforcing ribs 24 may be disposed on the side of the first cover plate 21, the second cover plate 22, and the bottom plate 23 away from the inner cylinder 10, or on the side of the first cover plate 21, the second cover plate 22, and the bottom plate 23 facing the inner cylinder 10, or extend from the side of the first cover plate 21, the second cover plate 22, and the bottom plate 23 away from the inner cylinder 10 to the other side facing the inner cylinder 10. The second reinforcing ribs 24 may extend from the side of the outer cylinder 10 near the opening end 13 of the inner cylinder 10 to the other side of the outer cylinder 10 near the bottom end 14 of the inner cylinder 10.

[0061] The second reinforcing rib 24 enhances the overall structural strength of the outer cylinder 20. The first cover plate 21, the second cover plate 22, and the bottom plate 23 have equal thicknesses, reducing matching difficulty. Since the first cover plate 21, the second cover plate 22, and the bottom plate 23 all have the second reinforcing rib 24, in some embodiments, the thickness of the first cover plate 21, the second cover plate 22, and the bottom plate 23 can be less than 3mm to reduce material costs. The second reinforcing rib 24 strengthens the structural strength of the first cover plate 21, the second cover plate 22, and the bottom plate 23, thereby enhancing the structural strength of the outer cylinder 20.

[0062] By setting the second reinforcing rib 24, in addition to enhancing the structural strength, the thickness of the first cover plate 21, the second cover plate 22 and the bottom plate 23 can be reduced, thereby reducing the structural weight and lowering production costs.

[0063] The clothes drying equipment 1000 also includes a first support plate 31 and a second support plate 32. The first support plate 31 is located at the open end 13 of the inner drum 10, and the second support plate 32 is located at the bottom end 14 of the inner drum 10. Please continue reading. Figure 3 The inner cylinder 10 has a first gap 131 between its open end 13 and the outer cylinder 20, and a third gap 132 between its open end 13 and the first support plate 31. The inner cylinder 10 has a second gap 141 between its bottom end 14 and the outer cylinder 20, and a fourth gap 142 between its bottom end 14 and the second support plate 32. The outer cylinder 20 covers the outside of the inner cylinder 10, with one end of the outer cylinder 20 sealed to the first support plate 31 and the other end sealed to the second support plate 32.

[0064] The opening end 13 of the inner cylinder 10 can be non-sealed with the first support plate 31, and the bottom end 14 of the inner cylinder 10 can also be non-sealed with the second support plate 32. One end of the outer cylinder 20 is sealed to the first support plate 31, and the other end is sealed to the second support plate 32. Therefore, some airflow can flow from the first cavity 10a into the second cavity 20a, but cannot flow from the second cavity 20a into the third cavity 80a. Thus, the second cavity 20a can serve as an insulation layer for the first cavity 10a, ensuring the insulation effect of the first cavity 10a, thereby improving drying efficiency and shortening drying time. In addition, the non-sealed connection between the inner cylinder 10 and the first support plate 31, as well as with the second support plate 32, reduces the rotational resistance of the inner cylinder 10, achieving a balance between improving the insulation effect of the first cavity 10a and reducing the rotational resistance of the inner cylinder 10. This reduces the input power and energy consumption of the drying equipment 1000, and improves the drying effect of the drying equipment 1000.

[0065] During the operation of the dryer 1000, the outer cylinder 20 remains stationary, thus ensuring a good seal in the second chamber 20a. The hot, dry airflow in the second chamber 20a cannot flow into the third chamber 80a from between the outer cylinder 20 and the first support plate 31, or from between the outer cylinder 20 and the second support plate 32. This better prevents airflow leakage, reduces energy consumption, and improves the drying efficiency of the dryer 1000.

[0066] The first support plate 31 and the second support plate 32 are arranged opposite to each other. The inner cylinder 10 is disposed between the first support plate 31 and the second support plate 32. The outer cylinder 20 covers the inner cylinder 10 and is connected between the first support plate 31 and the second support plate 32. One end of the outer cylinder 20 is sealed to the first support plate 31, and the other end is sealed to the second support plate 32. The structure has strong stability and good sealing effect of the second cavity 20a, which prevents the dry and hot airflow in the second cavity 20a from directly exchanging heat with the external environment. This improves the heat preservation effect of the second cavity 20a on the first cavity 10a, effectively shortens the drying time, and improves the drying efficiency. Meanwhile, the dry, hot airflow from the second chamber 20a cannot flow into the third chamber 80a. This prevents the dry, hot airflow from condensing in the third chamber 80a, thus preventing damage to components such as the evaporator 91, condenser 92, compressor 94, throttling device 95, and connecting pipe 96 placed in the third chamber 80a from frost or condensate. This extends the service life of components such as the evaporator 91, condenser 92, compressor 94, throttling device 95, and connecting pipe 96, thereby extending the service life of the clothes drying equipment 1000 and improving the user experience.

[0067] The clothes drying device 1000 also includes a second seal 401 and a third seal 402. The second seal 401 is disposed in a first gap 131 between the open end 13 of the inner cylinder 10 and the outer cylinder 20, or in a third gap 132 between the inner cylinder 10 and the first support plate 31. The third seal 402 is disposed in a second gap 141 between the bottom end 14 of the inner cylinder 10 and the outer cylinder 20, or in a fourth gap 142 between the inner cylinder 10 and the second support plate 32.

[0068] The opening end 13 of the inner cylinder 10 is not sealed to the first support plate 31. The second seal 401 can be disposed on the first support plate 31, the inner cylinder 10, or the outer cylinder 20. When the second seal 401 is disposed on the inner cylinder 10, it can rotate with the rotation of the inner cylinder 10. The bottom end 14 of the inner cylinder 10 is not sealed to the second support plate 32. The third seal 402 can be disposed on the second support plate 32, the inner cylinder 10, or the outer cylinder 20. When the third seal 402 is disposed on the inner cylinder 10, it can rotate with the rotation of the inner cylinder 10. Since the second cavity 20a can serve as the insulation layer of the first cavity 10a, the opening end 13 of the inner cylinder 10 can contact the second seal 401, but no pressure needs to be applied to the second seal 401. The bottom end 14 of the inner cylinder 10 can contact the third seal 402, but no pressure needs to be applied to the third seal 402. This greatly reduces the rotational resistance of the inner cylinder 10, thereby reducing the input power and energy consumption of the dryer 1000 and improving the energy efficiency level of the dryer 1000.

[0069] By providing a second sealing element 401 at the opening end 13 of the inner cylinder 10 and a third sealing element 402 at the bottom end 14 of the inner cylinder 10, the hot and dry airflow in the first cavity 10a is blocked by the second sealing element 401 and the third sealing element 402, thereby ensuring the airtightness of the opening end 13 and the bottom end 14 of the inner cylinder 10 and preventing the hot and dry airflow in the first cavity 10a from directly flowing into the second cavity 20a. This improves the sealing and heat preservation effect of the first cavity 10a to a certain extent, thereby shortening the drying time and improving the drying efficiency of the drying equipment 1000.

[0070] The second seal 401 and the third seal 402 can be annular elastic seals. The inner cylinder 10 is cylindrical, and the outer cylinder 20 is also cylindrical in overall structure. The radial cross-sections of the open end 13 and the bottom end 14 of the inner cylinder 10 are both annular structures, and the radial cross-sections of the two ends of the outer cylinder 20 that are axially opposite each other are also annular structures. Therefore, setting the second seal 401 as an annular structure can reduce the matching difficulty between the second seal 401 and the open end 13 of the inner cylinder 10 and the end of the outer cylinder 20 near the first support plate 31; setting the third seal 402 as an annular structure can reduce the matching difficulty between the third seal 402 and the bottom end 14 of the inner cylinder 10 and the end of the outer cylinder 20 near the second support plate 32.

[0071] The materials of the second seal 401 and the third seal 402 can both be selected from rubber, silicone, sponge, or wool felt. Rubber, silicone, sponge, and wool felt all have good elasticity and a long service life. The elasticity of the second seal 401 and the third seal 402 provides a buffering effect for the inner cylinder 10. At the same time, it ensures that the gaps at all points of connection between the inner cylinder 10 and the first support plate 31 are equal, and it also ensures that the gaps at all points of connection between the inner cylinder 10 and the second support plate 32 are equal, resulting in more uniform drying of the material to be dried.

[0072] The inner cylinder 10 has an extension 50, which is located at the open end 13 of the inner cylinder. The extension 50 has an air outlet 51, which can be arranged in the same direction as the first opening 15. The extension 50 is fixedly connected to the inner cylinder 10 or integrally formed. Integral forming can improve the airtightness and structural strength of the inner cylinder 10. Fixed connection methods include, but are not limited to, riveting, welding, or bolting. The extension 50 and the inner cylinder 10 can maintain a sealed connection, thereby ensuring that the inner cylinder 10 has a certain degree of airtightness. The connection method between the extension 50 and the inner cylinder 10 can be arbitrarily selected, as long as the extension 50 and the inner cylinder 10 maintain a sealed connection. The air outlet 51 of the extension 50 is staggered from the second sealing member 401 to prevent the second sealing member 401 from blocking the air outlet 51.

[0073] An extension 50 is disposed on the side of the inner cylinder sidewall 11 opposite to the inner cylinder bottom wall 12. The extension 50 can extend from the inner cylinder bottom wall 12 toward the axis of the inner cylinder 10, or extend from the inner cylinder bottom wall 12 in a direction opposite to the axis of the inner cylinder 10. The extension direction of the extension 50 can be perpendicular to the axis of the inner cylinder 10, or the extension direction of the extension 50 can be inclined inward or outward relative to the radial direction of the inner cylinder 10. The extension 50 can form an air outlet 51 by internal hollowing out. The air outlet 51 can be composed of multiple air holes, and the radial cross-section of the air holes can be circular, square, or rhomboid. The specific shape of the air holes can be arbitrarily selected as needed and is not limited here. The axis of the air outlet 51 can be parallel to or intersect with the axis of the inner cylinder 10.

[0074] The bottom wall 12 of the inner cylinder has an air inlet 121. The airflow in the first cavity 10a enters the first cavity 10a through the air inlet 121 and then flows out through the air outlet 51. This airflow can be a dry, hot airflow generated by the condenser 92. The air inlet 121 can be composed of multiple air inlets, and the axial direction of the air inlets can be parallel to the axial direction of the inner cylinder 10. The radial cross-section of the air inlets can be circular to further accelerate the flow of the dry, hot airflow into the first cavity 10a, allowing the first cavity 10a to heat up quickly, thereby shortening the drying time and improving the drying efficiency of the drying equipment 1000.

[0075] The bottom wall 12 of the inner cylinder includes multiple air inlet areas 12a and multiple sealing areas 12b, which are spaced apart. Each air inlet area 12a has multiple air inlets to form an air inlet 121. The air inlet 121 is located in the air inlet area 12a and should be a certain distance away from the sealing area 12b to ensure the stability of the sealing area 12b structure, thereby improving the overall stability of the inner cylinder 10 structure.

[0076] The plane containing the sealing area 12b can be the same plane as the plane containing the air inlet area 12a, or it can protrude from the plane containing the air inlet area 12a. The portion of the plane containing the sealing area 12b that protrudes from the plane containing the air inlet area 12a can be called a protruding surface. The protruding surface can be a smooth surface to avoid damaging the clothes to be dried during the operation of the drying equipment 1000. When the plane containing the sealing area 12b protrudes from the plane containing the air inlet area 12a, the sealing area 12b can protrude along the axial direction of the inner cylinder 10 towards the side of the first cavity 10a, or along the axial direction of the inner cylinder 10 towards the side of the first cavity 10a, or along the axial direction of the inner cylinder 10 towards both sides of the bottom wall 12 of the inner cylinder, in order to improve the structural stability of the sealing area 12b and thus improve the structural strength of the inner cylinder 10.

[0077] The third seal 402 can be arranged around the air inlet 121 so that the third seal 402 and the air inlet 121 are staggered, thereby preventing the third seal 402 from blocking the air inlet 121.

[0078] The first support plate 31 has a second opening 311 communicating with the first opening 15, and the first support plate 31 also has a first exhaust port 312 communicating with the air outlet 51. The object to be dried can be placed into the first cavity 10a through the second opening 311 and the first opening 15 in sequence. The airflow in the first cavity 10a after heat exchange with the object to be dried can flow out of the first cavity 10a through the air outlet 51 and the first exhaust port 312 in sequence.

[0079] The second support plate 32 has a vent 321 that cooperates with the air inlet 121. Specifically, the second support plate 32 has multiple ventilation areas 32a and multiple support parts 323, with the ventilation areas 32a and support parts 323 spaced apart. The multiple ventilation areas 32a correspond to multiple air inlet areas 12a on the bottom wall 12 of the inner cylinder, and the multiple support parts 323 correspond to multiple sealing areas 12b on the bottom wall 12 of the inner cylinder. Each ventilation area 32a can correspond to one vent 321, or each ventilation area 32a can correspond to multiple vents 321, with the vents 321 corresponding to the air inlet 121. Dry, hot airflow from outside the inner cylinder 10 passes sequentially through the vents 321 and the air inlets 121 into the first cavity 10a.

[0080] The housing 80 includes opposing side shells 81, and opposing top shells 82 and bottom shells 83. The side shells 81 are positioned opposite each other on both sides of the housing 80. The plane containing the side shells 81 is perpendicular to the plane containing the first support plate 31 and the plane containing the second support plate 32. The side shells 81 are connected between the first support plate 31 and the second support plate 32. The plane containing the top shell 82 is perpendicular to the plane containing the first support plate 31 and the plane containing the second support plate 32. The top shell 82 is connected between the first support plate 31 and the second support plate 32, and is located on the side of the inner cylinder 10 opposite to the bottom plate 23. The plane containing the bottom shell 83 is perpendicular to the plane containing the first support plate 31 and the plane containing the second support plate 32. The bottom shell 83 is connected between the first support plate 31 and the second support plate 32, and is located on the side of the bottom plate 23 opposite to the inner cylinder 10.

[0081] A fixing plate 231 is provided on the side of the bottom plate 23 of the outer cylinder 20 facing away from the inner cylinder 10. The fixing plate 231 extends from the bottom plate 23 in the direction away from the inner cylinder 10. The fixing plate 231 has mounting holes, and a fastener cooperates with the mounting holes to fix the fixing plate 231 to the second support plate 32, thereby further ensuring the structural strength of the outer cylinder 20. The fixing plate 231 and the bottom plate 23 are either sealed together or integrally formed. Integral forming can improve the airtightness of the connection between the fixing plate 231 and the bottom plate 23 and enhance the overall structural strength of the fixing plate 231 and the bottom plate 23. The sealing connection method includes, but is not limited to, riveting, welding or bolting. The sealing connection method is not limited here, as long as the fixing plate 231 and the bottom plate 23 maintain a sealed connection.

[0082] Please refer to the following: Figures 9 to 10 , Figure 9 This is a schematic diagram of one embodiment of the heat pump system for the clothes drying equipment provided in this application. Figure 10 This is a schematic diagram of another embodiment of the heat pump system of the clothes drying equipment provided in this application. The clothes drying equipment 1000 also includes a heat pump system 90. The heat pump system 90 includes an evaporator 91, a condenser 92, an air supply component 93, a compressor 94, and a throttling component 95. The third cavity 80a has an inner circulation cavity 80b and an outer circulation cavity 80c that are isolated from each other. The inner circulation cavity 80b is connected to the first cavity 10a, and the outer circulation cavity 80c is connected to the external environment. The evaporator 91 and the condenser 92 are disposed in the inner circulation cavity 80b. The compressor 94 and the throttling component 95 are disposed in the outer circulation cavity 80c. The air supply component 93 is disposed in the airflow path from the inner circulation cavity 80b to the first cavity 10a. In addition, the motor body 971 is also located in the outer circulation cavity 80c.

[0083] Both the evaporator 91 and the condenser 92 are located in the inner circulation chamber 80b, while other components such as the compressor 94, the throttling device 95, and the connecting pipes 96 are located in the non-inner circulation chamber 80c. The outer cylinder 20 is separated from the compressor 94, the throttling device 95, and the connecting pipes 96 in the non-inner circulation chamber 80c by a certain distance. This prevents the outer cylinder 20 from being deformed or damaged due to heat conduction from the high-temperature pipes, thus extending the service life of the outer cylinder 20.

[0084] The housing 80 includes a bottom shell 83, which is located on the side of the bottom plate 23 opposite to the inner cylinder 10. An inner circulation cavity 80b and an outer circulation cavity 80c are located between the bottom shell 83 and the bottom plate 23. A surrounding plate 831 is provided on the side of the bottom shell 83 facing the bottom plate 23. The surrounding plate 831 extends from the bottom shell 83 towards the bottom plate 23. The bottom shell 83, the surrounding plate 831, and the bottom plate 23 together form the inner circulation cavity 80b.

[0085] The enclosure 831 and the bottom shell 83 are either sealed together or integrally formed. Integral forming improves the airtightness of the connection between the enclosure 831 and the bottom shell 83, and enhances the overall structural strength of the enclosure 831 and the bottom shell 83. Sealing methods include, but are not limited to, riveting, welding, or bolting. The sealing method is not limited here, as long as a sealed connection is maintained between the enclosure 831 and the bottom shell 83.

[0086] The enclosure 831 includes a front panel 8311, a rear panel 8312, and a side panel 8313. The rear panel 8312 is disposed on the side of the bottom shell 83 away from the first support plate 31, the front panel 8311 is disposed on the side of the bottom shell 83 away from the second support plate 32, and the side panels 8313 are disposed opposite to the front panel 8311 and the rear panel 8312.

[0087] The inner circulation chamber 80b has an air inlet 801 and a first air outlet 831a. The air inlet 801 can be disposed on the front plate 8311, and the first air outlet 831a can be disposed on the rear plate 8312. In some embodiments, the first air outlet 831a can be partially disposed on the fixed plate 231 and partially disposed on the rear plate 8312. The evaporator 91 and the condenser 92 are arranged sequentially from the air inlet 801 toward the first air outlet 831a. The evaporator 91 is disposed on the side of the condenser 92 away from the first air outlet 831a, that is, the windward side of the inner circulation chamber 80b, so that the evaporator 91 can cool and dehumidify the low-temperature, high-humidity airflow flowing in from the air inlet 801. The condenser 92 is disposed on the side of the evaporator 91 away from the air inlet 801, that is, the leeward side of the inner circulation chamber 80b, so that the condenser 92 can output dry, hot airflow to the first chamber 10a.

[0088] A duct 101 is formed between the front panel 100 and the first support plate 31. The open end 13 of the inner cylinder 10 has an air outlet 51. The first support plate 31 has a first exhaust port 312 and a second exhaust port 313. The first exhaust port 312 corresponds to the air outlet 51 of the inner cylinder 10. The second exhaust port 313 corresponds to the air inlet 801 of the inner circulation cavity 80b. The duct 101 connects the first exhaust port 312 and the second exhaust port 313. Air in the first cavity 10a is discharged from the air outlet 51, enters the duct 101 through the first exhaust port 312, and then enters the inner circulation cavity 80b through the duct 101, passing sequentially through the second exhaust port 313 and the air inlet 801.

[0089] The air duct 101 can be a connecting pipe 96, a sealing structure that is sealed between the first support plate 31 and the front panel 100, or other sealed pipes. The specific structure of the air duct 101 can be arbitrarily selected as long as it can achieve the function of this application.

[0090] The clothes drying equipment also includes a filter element 314, which is disposed at the first exhaust port 312 and / or the second exhaust port 313. The filter element 314 can be a filter screen. The filter element 314 can be disposed at the first exhaust port 312, the second exhaust port 313, or both, to filter out lint and other debris falling during the operation of the clothes drying equipment 1000. This prevents the air duct 101 between the first exhaust port 312 and the second exhaust port 313 from becoming blocked, thus affecting the exhaust efficiency of the first cavity 10a. Simultaneously, it prevents lint and other debris from sequentially entering the inner circulation cavity 80b through the air inlet 801, the first exhaust port 312, the air duct 101, the second exhaust port 313, and the air inlet 801, thereby preventing the dehumidification effect of the evaporator 91 and the heating effect of the condenser 92 from being affected.

[0091] The clothes dryer 1000 also includes a cover plate 70, which covers the second support plate 32 on the side opposite to the outer cylinder 20 to form an air supply chamber 70a. The air supply chamber 70a is connected between the first cavity 10a and the inner circulation cavity 80b. The air supply chamber 70a is connected to the first cavity 10a through a vent 321 and an air inlet 121.

[0092] The second support plate 32 is also provided with a second air outlet 322, which corresponds to the first air outlet 831a. The second air outlet 322 is completely located within the air supply cavity 70a formed by the cover plate 70 covering the two support plates 32, so that the internal circulation cavity 80b cannot communicate with the external environment through the first air outlet 831a and the second air outlet 322, thereby ensuring the airtightness of the internal circulation cavity 80b.

[0093] The clothes drying equipment 1000 also includes an air supply component 93, which can be disposed at the first air outlet 831a or the second air outlet 322, or spanning both the first air outlet 831a and the second air outlet 322, or disposed in the inner circulation chamber 80b, or disposed in the air supply chamber 70a, so as to send the dry and hot airflow after heat exchange by the condenser 92 into the air supply chamber 70a through the first air outlet 831a and the second air outlet 322. The air supply component 93 can be a fan.

[0094] In some embodiments, the air supply component 93 delivers the dry, hot airflow after heat exchange with the condenser 92 from the inner circulation chamber 80b through the first air outlet 831a and the second air outlet 322 into the air supply chamber 70a, so that the inner circulation chamber 80b is in a negative pressure state. The dry, hot air flowing into the air supply chamber 70a flows along the direction from the second air outlet 322 to the vent 321, and flows into the first cavity 10a in sequence through the vent 321 and the air inlet 121. The dry, hot air flows from the bottom end 14 of the inner cylinder 10 to the opening end 13 in the first cavity 10a. After heat exchange with the object to be dried, the water vapor carrying the object to be dried flows into the inner circulation chamber 80b in sequence from the air outlet 51 on the extension 50, the first exhaust air outlet 312 on the first support plate 31 and the air inlet 801, thereby realizing the airflow circulation of the first cavity 10a, the inner circulation chamber 80b and the air supply chamber 70a.

[0095] Please refer to the following: Figure 11 , Figure 11 This is a schematic diagram of the internal airflow circulation of an embodiment of the drying equipment provided in this application, wherein the arrows indicate the direction of airflow circulation. Under the action of the air supply component 93, the hot, dry airflow sequentially flows into the air supply cavity 70a through the first air supply port 831a and the second air supply port 322 on the second support plate 32. After entering the air supply cavity 70a, the hot, dry airflow sequentially flows into the first cavity 10a through the vent 321 and the air inlet 121. After entering the first cavity 10a, the hot, dry airflow flows from the air inlet 121 to the air outlet 51. During its flow within the first cavity 10a, the hot, dry airflow exchanges heat with the items to be dried, forming a low-temperature, high-humidity airflow. The low-temperature, high-humidity airflow flows sequentially through the air outlet 51 on the extension 50 and the first exhaust vent 312 on the first support plate 31 into the air duct 101 between the first support plate 31 and the front panel 100. After entering the air duct 101, the low-temperature, high-humidity airflow flows along the first exhaust vent 312 towards the second exhaust vent 313 on the first support plate 31, and then sequentially through the second exhaust vent 313 and the air inlet 801 into the inner circulation chamber 80b. The low-temperature, high-humidity airflow entering the inner circulation chamber 80b first contacts the evaporator 91, which dehumidifies and cools the airflow. The compressor 94 pressurizes the airflow after it has been dehumidified and cooled by the evaporator 91, forming a high-temperature, high-pressure gas. This gas then enters the condenser 92, forming a dry, hot airflow. Under the action of the air supply component 93, the dry, hot airflow sequentially flows through the first air supply vent 831a and the second air supply vent 322 on the second support plate 32 into the air supply chamber 70a, thus forming a closed loop.

[0096] Please refer to the following: Figure 12 , Figure 12This is a three-dimensional structural schematic diagram of one embodiment of the support component of the clothes drying device provided in this application. The clothes drying device 1000 includes two support components 33. In some embodiments, the two support components 33 may be disposed between a first support plate 31 and an outer cylinder 20. Specifically, the support component 33 includes a support wheel 331 and a first support shaft 332. The support wheel 331 is disposed between the first support plate 31 and the outer cylinder 20, and the first support shaft 332 passes through the support wheel 331. One end of the first support shaft 332 is disposed on the first support plate 31, and the other end is disposed on the outer cylinder 20. Of the two support components 33, one may be disposed on the side of the first cover plate 21 near the bottom plate 23, and the other may be disposed on the side of the second cover plate 22 near the bottom plate 23, or both support components 33 may be disposed on the bottom plate 23. In other embodiments, the two support components 33 may be disposed between the inner cylinder 10 and the outer cylinder 20. Specifically, the support wheel 331 is rotatably disposed between the inner cylinder 10 and the outer cylinder 20, and the first support shaft 332 passes through the support wheel 331. One end of the first support shaft 332 is disposed on the first support plate 31, and the other end is disposed on the side of the support wheel 331 away from the first support plate 31.

[0097] Two support members 33 can be arranged opposite each other on both sides of the inner cylinder 10, and the surface of the support wheel 331 facing away from the bottom plate 23 is in contact with the inner cylinder 10. The two support members 33 provide support for the inner cylinder 10. The extension direction of the first support shaft 332 of the two support members 33 can be parallel to the axis of the inner cylinder 10. When the inner cylinder 10 rotates relative to the outer cylinder 20, the corresponding support wheel 331 of the two support members 33 can rotate with the rotation of the inner cylinder 10, thereby reducing the frictional resistance between the inner cylinder 10 and the two support members 33, reducing the input power and energy consumption of the drying equipment 1000, and improving the energy efficiency of the drying equipment 1000. The setting of the first support shaft 332 can play a sealing role, preventing the airflow in the second cavity 20a from flowing out through the mounting hole of the support member 33, and preventing outside air from flowing into the second cavity 20a through the mounting hole of the support member 33, thereby improving the heat preservation effect of the second cavity 20a, shortening the drying time, and improving the drying efficiency of the drying equipment 1000. The outer wall of the support wheel 331 is separated from the outer cylinder 20 by a certain distance to prevent the support wheel 331 from scratching the outer cylinder 20 during rotation.

[0098] By setting two support members 33, the open end 13 of the inner cylinder 10 is set on the two support members 33, so that the center of gravity of the inner cylinder 10 remains stable. To a certain extent, it can prevent radial and axial runout when the inner cylinder 10 rotates, thereby ensuring the stable rotation of the inner cylinder 10.

[0099] Please refer to the following: Figures 13 to 14 , Figure 13 This is a three-dimensional schematic diagram of the inner drum of the clothes drying device provided in this application. Figure 14This is a three-dimensional structural diagram of the embodiment of the inner drum and the second support plate of the clothes drying device provided in this application. The clothes drying device 1000 also includes a bearing 61, which is disposed between the inner drum 10 and the second support plate 32. The inner drum 10 is rotatably disposed on the second support plate 32 via the bearing 61. Specifically, the clothes drying device 1000 also includes a locking member 62 and a second support shaft 63, with the locking member 62 disposed on the side of the second support shaft 63 opposite to the inner drum 10.

[0100] The inner cylinder bottom wall 12 has a first shaft hole 122 at its center, and the second support plate 32 has a second shaft hole 324 that mates with the first shaft hole 122. Both the first shaft hole 122 and the second shaft hole 324 can be through holes. The locking member 62 has a third shaft hole 621. The first shaft hole 122, the second shaft hole 324 and the third shaft hole 621 mate with each other in pairs.

[0101] In some embodiments, a second support shaft 63 is first inserted into a bearing 61, with both ends of the second support shaft 63 extending beyond the end faces of the bearing 61. Then, one end of the second support shaft 63 is inserted into a first shaft hole 122 at the center of the inner cylinder bottom wall 12, and a fastener secures the second support shaft 63 in the first shaft hole 122. The other end is inserted into a second shaft hole 324 of the second support plate 32 and a third shaft hole 621 of the locking member 62, so that the locking member 62 secures the second support shaft 63 to the second support plate 32, thereby rotatably supporting the inner cylinder 10 on the second support plate 32, achieving a rotatable connection of the inner cylinder 10. The bearing 61 connects the second support plate 32 and the inner cylinder 10. The bearing 61 not only supports the inner cylinder 10 but also reduces the coefficient of friction during the rotation of the inner cylinder 10, limiting radial and axial runout during rotation. Simultaneously, it reduces the power consumption of the drying equipment 1000.

[0102] The bottom end 14 of the inner cylinder 10 is rotatably mounted on the second support plate 32 via a bearing 61. The open end 13 of the inner cylinder 10 is rotatably mounted on the first support plate 31 via two support members 33. The two support members 33 are located on both sides of the open end 13 of the inner cylinder 10. The two support members 33 and the bearing 61 work together to form a three-point fixing structure, thereby rotatably supporting the inner cylinder 10 between the first support plate 31 and the second support plate 32, making the structure more stable.

[0103] The clothes drying equipment 1000 also includes a door 110. The door 110 is rotatably mounted on the front panel 100 and is used to open or close the opening 100a, the second opening 311, and the first opening 15. When the user needs to put items to be dried into the inner drum 10, the door 110 is opened, and the items can be placed into the first cavity 10a of the inner drum 10 through the opening 100a, the second opening 311, and the first opening 15 of the inner drum 10. Then, the door 110 is closed, and the clothes drying equipment 1000 is ready to start drying operations. Similarly, when the user needs to remove items from the inner drum 10, the door 110 is opened, and the items can be removed from the first cavity 10a of the inner drum 10 through the opening 100a, the second opening 311, and the first opening 15 of the inner drum 10.

[0104] This application provides a clothes drying device, comprising: an inner drum having a first cavity, the inner drum including an open end and a bottom end arranged axially opposite to each other; an outer drum covering the outside of the inner drum to form a second cavity between the inner drum and the outer drum, the outer drum including a mounting part located on the side of the outer drum opposite to the inner drum, the mounting part having a receiving cavity, the receiving cavity having a first through hole on the side facing the open end or the bottom end; a motor having a motor body, a drive rod and a drive wheel connected in sequence, the motor body being located outside the outer drum, the drive rod passing through the first through hole, and the drive wheel being disposed in the receiving cavity; and a belt sleeved on the drive wheel and the inner drum, thereby placing the motor outside the outer drum, improving the heat dissipation effect of the motor, and thus extending the service life of the clothes drying device.
