[0037] Please refer to Figures 1 to 4 , Figure 1 is a perspective view of a drying apparatus provided by the application; Figure 2 is an exploded perspective view of a drying apparatus provided by the application; Figure 3 is a perspective view of a drying apparatus provided by the application; Figure 4 is a cross-sectional view of an embodiment of a drying apparatus provided by the application. The application provides a drying apparatus 1000. The drying apparatus 1000 comprises an inner drum 10, an outer drum 20, and a housing 80, wherein the inner drum 10 is a rotating drum and the outer drum 20 is a fixed drum. During operation of the drying apparatus 1000, the outer drum 20 remains stationary and the inner drum 10 rotates relative to the outer drum 20.

The housing 80 comprises a top housing 81 and a bottom housing 82, which are arranged opposite to each other on two sides of the outer drum 20 away from the inner drum 10 to form a third cavity 80a between the outer drum 20 and the housing 80. The inner drum 10 and the outer drum 20 are coaxially arranged at a distance from each other, so as to avoid interference between the inner drum 10 and the outer drum 20 when the inner drum 10 jumps in the radial and axial directions during rotation. The coaxial arrangement of the inner drum 10 and the outer drum 20 can reduce the volume of the outer drum 20, making the structure more compact, reducing production costs, and reducing the structural mass.

[0038] The inner drum 10 forms a first cavity 10a inside, the second cavity 20a is formed between the inner drum 10 and the outer drum 20, and the third cavity 80a is formed between the outer drum 20 and the housing 80. The first cavity 10a is used to place the objects to be dried. The second cavity 20a can play a heat preservation role to reduce the heat dissipation rate of the first cavity 10a, thereby reducing the energy consumption of the drying apparatus 1000 and improving the energy efficiency of the drying apparatus 1000. The third cavity 80a can be used to place components such as an evaporator 91, a condenser 92, a blowing piece 93, a compressor 94, a throttling piece 95, and a connecting pipeline 96.

[0039] During operation of the drying apparatus 1000, the objects to be dried are constantly turned over in the first cavity 10a under the rotating action of the inner drum 10, and the dry hot airflow fully exchanges heat with the objects to be dried, so that the moisture of the objects to be dried evaporates and is discharged with the dry hot airflow.

[0040] The inner cylinder 10 comprises an inner cylinder sidewall 11 and an inner cylinder bottom wall 12. The inner cylinder sidewall 11 is fixedly connected or integrally formed with the inner cylinder bottom wall 12, and the fixedly connected manner includes but is not limited to riveting, welding and the like.

The outer cylinder 20 comprises a top cover plate 21, a bottom cover plate 22, and the first side plate 23 and the second side plate 24 oppositely arranged. The bottom cover plate 22 is located at the side of the outer cylinder 20 facing the bottom shell 82. The top cover plate 21 is located at the side of the outer cylinder 20 facing the top shell 81. The top cover plate 21 and the bottom cover plate 22 are arranged in a spaced manner, and the end faces of any one side adjacent to the top cover plate 21 and the bottom cover plate 22 are spaced apart by at least a certain distance. The side adjacent to the top cover plate 21 and the bottom cover plate 22 is sealingly connected to the first side plate 23, and the other side adjacent to the top cover plate 21 and the bottom cover plate 22 is sealingly connected to the second side plate 24. By sealingly connecting the top cover plate 21, the bottom cover plate 22, the first side plate 23 and the second side plate 24, an integral structure is formed, so that the first side plate 23 and the second side plate 24 can serve as a part of the outer cylinder 20 or a part of the outer shell 80, thereby simplifying the number of parts, reducing the structural weight, and reducing the assembly process and saving the working hours during the assembly of the clothes drying apparatus 1000, thereby improving the assembly efficiency.

[0042] The surfaces of the top cover plate 21 and the bottom cover plate 22 facing the inner cylinder 10 are arc surfaces, which are convex arc surfaces facing away from the inner cylinder 10, that is, the top cover plate 21 and the bottom cover plate 22 are arc-shaped structures. The top cover plate 21 and the bottom cover plate 22 are designed to be arc-shaped, which facilitates cooperation with the inner cylinder 10, and at the same time, reduces the volume of the top cover plate 21 and the bottom cover plate 22, further reduces the structural weight, and the top cover plate 21 and the bottom cover plate 22 are spaced apart from the inner cylinder 10 by a certain distance to form a second cavity 20a between the outer cylinder 20 and the inner cylinder 10.

[0043] The first side plate 23 and the second side plate 24 extend beyond the top of the top cover plate 21 at a side of the top cover plate 21, that is, the highest point of the top cover plate 21 away from the inner cylinder 10. The first side plate 23 and the second side plate 24 extend beyond the bottom of the bottom cover plate 22 at a side of the bottom cover plate 22, that is, the lowest point of the bottom cover plate 22 away from the inner cylinder 10. The side of the top cover plate 21 and the bottom cover plate 22 adjacent to each other can be sealingly connected to the inner wall of the first side plate 23, and the other side of the top cover plate 21 and the bottom cover plate 22 adjacent to each other can be sealingly connected to the inner wall of the second side plate 24. The shell 80 includes a top shell 81 and a bottom shell 82, the top shell 81 is arranged at the end of the first side plate 23 and the second side plate 24 at the side of the top cover plate 21, and the bottom shell 82 is arranged at the end of the first side plate 23 and the second side plate 24 at the side of the bottom cover plate 22, so as to form a third cavity 80a between the top shell 81 and the top cover plate 21, and between the bottom shell 82 and the bottom cover plate 22.

[0044] In some embodiments, in the top cover plate 21 and the bottom cover plate 22, any one of the planes in which the end faces of the first side plate 23 are located can be parallel to the plane in which the first side plate 23 is located, and any one of the planes in which the end faces of the second side plate 24 are located can be parallel to the plane in which the second side plate 24 is located. During the manufacturing process of the clothes drying device 1000, it is convenient for the operator to assemble, reduces the difficulty of assembly, and makes it easier to achieve sealing connection between the top cover plate 21 and the first side plate 23 and the second side plate 24, and between the bottom cover plate 22 and the first side plate 23 and the second side plate 24, thereby further improving the assembly efficiency.

[0045] The end face of the side of the top cover plate 21 and the bottom cover plate 22 adjacent to each other is provided with a first sealing member 403 between the first side plate 23, and the end face of the other side of the top cover plate 21 and the bottom cover plate 22 adjacent to each other is provided with a second sealing member 404 between the second side plate 24, so as to ensure the sealing connection between the side of the top cover plate 21 and the bottom cover plate 22 adjacent to each other and the first side plate 23, and to ensure the sealing connection between the other side of the top cover plate 21 and the bottom cover plate 22 adjacent to each other and the second side plate 24, thereby improving the air tightness of the second cavity 20a.

[0046] The first sealing member 403 and the second sealing member 404 can be elastic sealing members for isolating the second cavity 20a from the external environment, which can effectively improve the sealing effect. The first sealing member 403 and the second sealing member 404 are box-shaped elastic sealing members. In some embodiments, the first sealing member 403 and the second sealing member 404 can also be strip-shaped elastic sealing members. When the shape of the end face of the top cover plate 21 and the bottom cover plate 22 adjacent to the first side plate 23 or the second side plate 24 changes, the shape of the first sealing member 403 and the second sealing member 404 can be changed to adapt. In other embodiments, the top cover plate 21 and the bottom cover plate 22 can be sealingly connected to the first side plate 23 or the second side plate 24 by welding, riveting or gluing.

[0047] The first seal 403 and the second seal 404 can be made of a sealing material selected from silica gel, rubber, or polytetrafluoroethylene. The first seal 403 and the second seal 404 have elasticity and function to seal the gas, so that the air tightness of the outer cylinder 20 is better, the structure is more reliable, the structural strength is improved, and in addition, the vibration generated by the mutual friction between the top cover plate 21 and the first side plate 23 and / or the second side plate 24 and between the bottom cover plate 22 and the first side plate 23 and / or the second side plate 24 during the operation of the clothes drying apparatus 1000 can be alleviated, thereby reducing the generation of noise.

[0048] The clothes drying apparatus 1000 further includes a water box 40 disposed on the top cover plate 21 on a side close to the first side plate 23 and / or the second side plate 24. The water box 40 can be disposed on the top cover plate 21 on a side close to the first side plate 23, or on a side close to the second side plate 24, or on a side close to both the first side plate 23 and the second side plate 24. The water box 40 can be a water collecting box for collecting condensed water generated during the operation of the clothes drying apparatus 1000, or a spray box for storing a care liquid, a mosquito repellent liquid, and a fragrance solvent.

When the base 41 and the top cover plate 21, or the cover 42 and the base 41 are in a fixed connection structure, the fixed connection manner includes, but is not limited to, a riveting connection, a welding connection, or a bolt connection. When the base 41 and the top cover plate 21, or the cover 42 and the base 41 are in an integrally formed structure, the structure of the water box 40 is simplified, the assembly process is reduced, and the part processing, the whole machine assembly, and the maintenance are facilitated.

[0050] The base 41 comprises a flange 411 which is sealingly connected or integrally formed with the base 41, and the sealingly connected manner comprises but is not limited to riveting, welding or bolt connection and the like. The flange 411 extends away from the top cover plate 21 to form a recess opening away from the top cover plate 21, which is a containing groove 40a of the water box 40, and an opening of the containing groove 40a is a groove opening 40b, and the cover body 42 covers the groove opening 40b. The water box body 43 is arranged in the containing groove 40a in a withdrawable manner. The base 41 of the water box 40 is provided with a first drainage port 41a, and of course, the first drainage port 41a can also be arranged on the flange 411. A second drainage port (not shown) corresponding to the first drainage port 41a is arranged on the water box body 43. The condensate water in the water box 40 can be discharged by using a drain pipe (not shown) and the first drainage port 41a and the second drainage port, or the care liquid, mosquito repellent liquid and fragrance solvent can be sucked into the water box 40 by using the drain pipe and the first drainage port 41a and the second drainage port.

[0051] In some embodiments, the first drainage port 41a and the second drainage port can also be water inlets. The condensate water generated during the operation of the clothes drying device 1000 can be sucked into the water box body 43 by using a drain pipe and the first drainage port 41a and the second drainage port. When the liquid level of the condensate water in the water box body 43 reaches a certain degree, the water box body 43 can be taken out to treat the condensate water in the water box body 43, thereby avoiding overflow of the condensate water.

[0052] The water box body 43 is arranged in the containing groove 40a in a withdrawable manner. The withdrawal opening 43a of the water box body 43 can be arranged on the same side as the open end 13 of the outer cylinder 10, or on the side of the clothes drying device 1000. The water box body 43 can be regularly taken out of the containing groove 40a to clean the water box body 43, thereby avoiding breeding of bacteria in the water box body 43 and causing pollution to the objects to be dried.

The first reinforcing structure 25 is located on the surface of the top cover plate 21 and the bottom cover plate 22 facing and / or away from the inner cylinder 10, and extends from one end of the surface facing the open end 13 to one end facing the bottom end 14 of the cylinder. The extension direction of the first reinforcing structure 25 can be parallel to the axis direction of the outer cylinder 20. The extension direction of the first reinforcing structure 25 can be flexibly arranged according to actual needs, for example, the extension direction of the first reinforcing structure 25 can also be perpendicular to the axis direction of the outer cylinder 20, or can also be longitudinal and transverse interlaced, or can also be inclined.

[0054] The first reinforcing structure 25 can be arranged on the side of the top cover plate 21 and the bottom cover plate 22 away from the inner cylinder 10, or on the side of the top cover plate 21 and the bottom cover plate 22 facing the inner cylinder 10, or extended from the side of the top cover plate 21 and the bottom cover plate 22 away from the inner cylinder 10 to the side facing the inner cylinder 10. The specific position of the first reinforcing structure 25 can be flexibly arranged according to actual needs.

[0055] By arranging the first reinforcing structure 25, the thickness of the top cover plate 21 and the bottom cover plate 22 is reduced under the premise of ensuring that the top cover plate 21 and the bottom cover plate 22 have sufficient strength, thereby further reducing the structural mass of the outer cylinder 20 and the material cost, and in addition, the outer cylinder 20 is not easy to be deformed by heat during the working process of the clothes drying device 1000.

[0056] The first side plate 23 and the second side plate 24 each have a second reinforcing structure 26. The second reinforcing structure 26 is arranged on the side of the first side plate 23 and the second side plate 24 facing and / or away from the inner cylinder 10. The second reinforcing structure 26 can be arranged on the side of the first side plate 23 and the second side plate 24 facing the inner cylinder 10, or on the side of the first side plate 23 and the second side plate 24 away from the inner cylinder 10, or on the side of the first side plate 23 and the second side plate 24 facing the inner cylinder 10 and on the side away from the inner cylinder 10. The extending direction of the second reinforcing structure 26 can be flexibly arranged according to actual needs, for example, the second reinforcing structure 26 can be transverse, longitudinal, longitudinal and transverse, or inclined. The shape of the second reinforcing structure 26 can also be flexibly arranged according to actual needs, and the shape of the second reinforcing structure 26 can be strip-shaped, ring-shaped, arc-shaped, or polygonal.

[0057] By arranging the second reinforcing structure 26, the thickness of the first side plate 23 and the second side plate 24 is reduced under the premise of ensuring that the first side plate 23 and the second side plate 24 have sufficient strength, thereby further reducing the structural mass of the outer cylinder 20 and the outer shell 80, and further reducing the overall structural mass of the clothes drying device 1000, and reducing the material cost.

[0058] The bottom cover plate 22 includes a bottom cover body 221, a first extension part 222, and a second extension part 223.

The first extension part 222 is disposed on the side of the bottom cover body 221 facing the first side plate 23. The second extension part 223 is disposed on the side of the bottom cover body 221 facing the second side plate 24. The surface of the bottom cover body 221 facing the inner drum 10 is an arc surface that protrudes in the direction facing the inner drum 10. The bottom cover body 221 can be used to place some components, making the structure more compact, thereby improving the space utilization of the clothes drying apparatus 1000, and to a certain extent, the volume of the clothes drying apparatus 1000 can be appropriately reduced. In some embodiments, the bottom cover body 221 can also be a horizontal surface, that is, the plane on which the bottom cover body 221 is located is parallel to the plane on which the bottom shell 82 is located.

[0059] The first extension part 222 includes a first inclined plate 2221 and a first horizontal plate 2222. The second extension part 223 includes a second inclined plate 2231 and a second horizontal plate 2232. The first inclined plate 2221 extends from the bottom cover body 221 to the top cover plate 21, and the second inclined plate 2231 extends from the bottom cover body 221 to the top cover plate 21, thereby increasing the depth of the bottom cover plate 22. The first horizontal plate 2222 extends from the first inclined plate 2221 to the first side plate 23, and the second horizontal plate 2232 extends from the second inclined plate 2231 to the second side plate 24. The plane on which the first horizontal plate 2222 is located and the plane on which the second horizontal plate 2232 is located can be parallel to the plane on which the bottom shell 82 is located, facilitating the sealing connection of the bottom cover plate 22 with the first side plate 23 and the second side plate 24, thereby further improving the strength and air tightness of the outer drum 20 structure.

[0060] The top cover plate 21 has a first avoiding groove 21a. The bottom cover plate 22 has a second avoiding groove 22a that cooperates with the first avoiding groove 21a. The first avoiding groove 21a and the second avoiding groove 22a are arranged along the circumference of the outer drum 20. The first avoiding groove 21a and the second avoiding groove 22a protrude in the direction away from the inner drum 10. The second avoiding groove 22a can be disposed on the first extension part 222 and the second extension part 223. The second avoiding groove 22a located on the first extension part 222 extends from the side of the first inclined plate 2221 close to the bottom cover body 221 to the end of the first horizontal plate 2222 facing the first side plate 23. The second avoiding groove 22a located on the second extension part 223 extends from the side of the second inclined plate 2231 close to the bottom cover body 221 to the end of the second horizontal plate 2232 facing the second side plate 24.

[0061] The clothes drying apparatus 1000 further comprises a motor 97 and a belt 98. The motor 97 has a motor body 971, a driving rod 972 and a driving wheel 973 connected in sequence. The motor body 971 is arranged on the bottom cover body 221, and the driving rod 972 is connected between the motor body 971 and the driving wheel 973. The belt 98 is sleeved on the driving wheel 973 and the inner cylinder 10, and the belt 98 is located at the part of the inner cylinder 10 and matches the first avoiding groove 21a and the second avoiding groove 22a.

[0062] The motor 97 drives the inner cylinder 10 to rotate through the driving rod 972, the driving wheel 973 and the belt 98. The first avoiding groove 21a and the second avoiding groove 22a can have a certain depth to avoid the belt 98 and avoid friction between the belt 98 and the outer cylinder 20, so as to reduce the rotation resistance of the inner cylinder 10 and improve the clothes drying effect of the clothes drying apparatus 1000. The depth of the first avoiding groove 21a and the second avoiding groove 22a can be less than 5 mm, which can not only limit the volume of the outer cylinder 20, but also prevent the outer cylinder 20 and the belt 98 from being deformed due to friction between the belt 98 and the outer cylinder 20 when the belt 98 rotates, so as to realize compact structure and reduce structural quality. In other embodiments, the motor 97 can also be arranged on the side of the bottom cover plate 22 away from the inner cylinder 10, that is, the motor 97 is arranged in the third cavity 80a.

[0063] The extension direction of the first avoiding groove 21a and the second avoiding groove 22a is perpendicular or intersects with the extension direction of the first reinforcing structure 25, so as to further improve the structural strength of the outer cylinder 20, so that the outer cylinder 20 is not easy to be deformed due to heat during the working process of the clothes drying apparatus 1000, and the service life is improved.

[0064] The clothes drying apparatus 1000 further comprises 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 cylinder 10. The second support plate 32 is located at the bottom end 14 of the inner cylinder. One end of the top cover plate 21 and the bottom cover plate 22 is sealingly connected with the first support plate 31, and the other end is sealingly connected with the second support plate 32. The first side plate 23 and the second side plate 24 are connected between the first support plate 31 and the second support plate 32. The first side plate 23 and the first support plate 31 and the second support plate 32 can be sealingly connected, or can be non-sealingly connected. The connection mode of the first side plate 23 and the first support plate 31 and the second support plate 32 can be selected as needed. The second side plate 24 and the first support plate 31 and the second support plate 32 can be sealingly connected, or can be non-sealingly connected. The connection mode of the second side plate 24 and the first support plate 31 and the second support plate 32 can be selected as needed.

[0065] The plane where the end face of the top cover plate 21 and the bottom cover plate 22 close to the first support plate 31 side is located can be parallel to the plane where the first support plate 31 is located. The plane where the end face of the top cover plate 21 and the bottom cover plate 22 close to the second support plate 32 side is located can be parallel to the plane where the second support plate 32 is located. During the manufacturing process of the clothes drying device 1000, the operation is convenient, the assembly difficulty is reduced, the sealing connection of the top cover plate 21 and the bottom cover plate 22 with the first support plate 31 and the top cover plate 21 and the bottom cover plate 22 with the second support plate 32 is more easily realized, the assembly efficiency is further improved, the sealing performance of the second cavity 20a is improved, the airflow in the second cavity 20a is prevented from flowing out from between the top cover plate 21 and the bottom cover plate 22 and the first support plate 31 or from between the top cover plate 21 and the bottom cover plate 22 and the second support plate 32, so that the second cavity 20a can serve as a heat preservation layer of the first cavity 10a, the heat preservation effect of the first cavity 10a is ensured, the drying efficiency is improved, the energy consumption of the clothes drying device 1000 is reduced, and the drying time is shortened.

[0066] The opening end 13 of the inner cylinder 10 and the first support plate 31 can be non-sealingly connected, the bottom end 14 of the inner cylinder 10 and the second support plate 32 can also be non-sealingly connected, one end of the outer cylinder 20 is sealingly connected with the first support plate 31, and the other end is sealingly connected with the second support plate 32, so that part of the 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, so that the second cavity 20a can serve as a heat preservation layer of the first cavity 10a, the heat preservation effect of the first cavity 10a is ensured, and the drying efficiency is improved, and the drying time is shortened. In addition, the inner cylinder 10 and the first support plate 31 and the second support plate 32 can be non-sealingly connected, which reduces the rotation resistance of the inner cylinder 10, realizes the simultaneous consideration of improving the heat preservation effect of the first cavity 10a and reducing the rotation resistance of the inner cylinder 10, thereby reducing the input power and energy consumption of the clothes drying device 1000, and improving the drying effect of the clothes drying device 1000.

[0067] During the operation of the clothes drying device 1000, the outer cylinder 20 always remains stationary, so that the second cavity 20a can maintain a good sealing state. The dry hot airflow in the second cavity 20a cannot flow from between the outer cylinder 20 and the first support plate 31 and from between the outer cylinder 20 and the second support plate 32 into the third cavity 80a, which can better prevent airflow leakage, reduce energy consumption, and improve the drying efficiency of the clothes drying device 1000.

[0068] The first support plate 31 and the second support plate 32 are oppositely arranged, the inner cylinder 10 is arranged between the first support plate 31 and the second support plate 32, and 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 sealingly connected with the first support plate 31, and the other end is sealingly connected with the second support plate 32, so that the structure is stable, the sealing effect of the second cavity 20a is good, the dry hot airflow in the second cavity 20a cannot directly exchange heat with the external environment, the heat preservation effect of the second cavity 20a on the first cavity 10a is improved, the drying time is effectively shortened, and the drying efficiency is improved. At the same time, the dry hot airflow in the second cavity 20a cannot flow into the third cavity 80a, so that the dry hot airflow cannot condense in the third cavity 80a after flowing into the third cavity 80a, thereby preventing the evaporator 91, the condenser 92, the compressor 94, the throttling member 95, the connecting pipeline 96 and other components placed in the third cavity 80a from being damaged by frost or condensed water, prolonging the service life of the evaporator 91, the condenser 92, the compressor 94, the throttling member 95, the connecting pipeline 96 and other components, and further prolonging the service life of the drying equipment 1000 and improving the user experience.

[0069] Please refer to Figure 5 , Figure 5 is a cross-sectional structure schematic diagram of another embodiment of the drying equipment provided by the present application. The drying equipment 1000 further comprises a third sealing member 401 and a fourth sealing member 402. The third sealing member 401 is arranged at the first gap 131 between the open end 13 of the inner cylinder 10 and the outer cylinder 20, or arranged at the third gap 132 between the inner cylinder 10 and the first support plate 31. The fourth sealing member 402 is arranged at the second gap 141 between the bottom end 14 of the inner cylinder 10 and the outer cylinder 20, or arranged at the fourth gap 142 between the inner cylinder 10 and the second support plate 32.

[0070] The opening end 13 of the inner cylinder 10 is non-sealingly connected with the first support plate 31, and the third sealing member 401 can be arranged on the first support plate 31, can be arranged on the inner cylinder 10, or can also be arranged on the outer cylinder 20. When the third sealing member 401 is arranged on the inner cylinder 10, the third sealing member 401 can rotate with the rotation of the inner cylinder 10. The bottom end 14 of the inner cylinder 10 is non-sealingly connected with the second support plate 32, and the fourth sealing member 402 can be arranged on the second support plate 32, can be arranged on the inner cylinder 10, or can also be arranged on the outer cylinder 20. When the fourth sealing member 402 is arranged on the inner cylinder 10, the fourth sealing member 402 can rotate with the rotation of the inner cylinder 10. Since the second cavity 20a can serve as a heat preservation layer of the first cavity 10a, the opening end 13 of the inner cylinder 10 can be in contact with the third sealing member 401, but the third sealing member 401 does not need to be subjected to pressure. The bottom end 14 of the inner cylinder 10 can be in contact with the fourth sealing member 402, but the fourth sealing member 402 does not need to be subjected to pressure. The rotating resistance of the inner cylinder 10 is greatly reduced, thereby reducing the input power and energy consumption of the clothes drying apparatus 1000 and improving the energy efficiency of the clothes drying apparatus 1000.

[0071] By arranging the third sealing member 401 at the opening end 13 of the inner cylinder 10 and arranging the fourth sealing member 402 at the bottom end 14 of the inner cylinder 10, the dry hot air flow in the first cavity 10a is blocked by the third sealing member 401 and the fourth sealing member 402, thereby ensuring the air tightness of the opening end 13 and the bottom end 14 of the inner cylinder 10 and avoiding the dry hot air flow in the first cavity 10a directly flowing into the second cavity 20a. To some extent, the sealing performance and heat preservation effect of the first cavity 10a are improved, thereby shortening the drying time and improving the drying efficiency of the clothes drying apparatus 1000.

[0072] The third sealing member 401 and the fourth sealing member 402 can be annular elastic sealing members, the inner cylinder 10 is in a cylindrical shape, the overall structure of the outer cylinder 20 is also in a cylindrical shape, the radial cross sections of the opening end 13 and the bottom end 14 of the inner cylinder 10 are both circular ring structures, and the radial cross sections of the two axially opposite ends of the outer cylinder 20 are also both circular ring structures. Therefore, the third sealing member 401 is arranged in an annular structure, which can reduce the matching difficulty of the third sealing member 401 with the opening end 13 of the inner cylinder 10 and with one end of the outer cylinder 20 close to the first support plate 31; the fourth sealing member 402 is arranged in an annular structure, which can reduce the matching difficulty of the fourth sealing member 402 with the bottom end 14 of the inner cylinder 10 and with one end of the outer cylinder 20 close to the second support plate 32.

[0073] The third sealing member 401 and the fourth sealing member 402 can be made of rubber, silica gel, sponge or wool felt. Rubber, silica gel, sponge and wool felt all have good elasticity and long service life. The third sealing member 401 and the fourth sealing member 402 have elasticity, which can buffer the inner cylinder 10, and at the same time, can ensure that the gaps at the connection between the inner cylinder 10 and the first support plate 31 are equal, and can also ensure that the gaps at the connection between the inner cylinder 10 and the second support plate 32 are equal, so that the drying of the to-be-dried objects is more uniform.

[0074] The inner cylinder 10 has an extension 50 arranged 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 or integrally formed with the inner cylinder 10. The integrally formed mode can improve the air tightness and structural strength of the inner cylinder 10. The fixed connection mode includes but is not limited to riveting, welding or bolt connection and the like. The extension 50 and the inner cylinder 10 can be sealingly connected, so as to ensure that the inner cylinder 10 has a certain air tightness. The connection mode of the extension 50 and the inner cylinder 10 can be arbitrarily selected, as long as the extension 50 and the inner cylinder 10 are sealingly connected. The air outlet 51 of the extension 50 is arranged staggered with the third sealing member 401, so as to avoid that the third sealing member 401 blocks the air outlet 51.

[0075] The extension 50 is arranged at the side of the inner cylinder side wall 11 away from the inner cylinder bottom wall 12. The extension 50 can extend from the inner cylinder bottom wall 12 to the axis direction of the inner cylinder 10, or extend from the inner cylinder bottom wall 12 to the direction away from 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 arranged inclined inward or outward relative to the radial direction of the inner cylinder 10. The extension 50 can form the air outlet 51 in an internally hollow manner, and the air outlet 51 can be composed of a plurality of air outlets. The radial section of the air outlet can be circular, square or rhombic, and the specific shape of the air outlet can be arbitrarily selected as required, which is not limited herein. The axis of the air outlet 51 can be parallel or intersected with the axis of the inner cylinder 10.

[0076] The inner cylinder bottom wall 12 has an air inlet 121, and the airflow in the first cavity 10a flows out of the air outlet 51 after entering the first cavity 10a from the air inlet 121. The airflow can be the dry hot airflow generated by the condenser 92. The air inlet 121 can be composed of a plurality of air inlets, and the axis direction of the air inlet can be parallel to the axis direction of the inner cylinder 10. The radial section of the air inlet can be circular, so as to further accelerate the speed of the dry hot airflow flowing into the first cavity 10a, so that the first cavity 10a can be quickly heated, thereby shortening the drying time and improving the drying efficiency of the drying equipment 1000.

[0077] The inner cylinder bottom wall 12 comprises a plurality of air inlet areas 12a and a plurality of sealing areas 12b, and the air inlet areas 12a and the sealing areas 12b are arranged at intervals. Each air inlet area 12a is provided with a plurality of air inlet holes to form an air inlet 121. The air inlet 121 is arranged in the air inlet area 12a, and the air inlet 121 should be spaced apart from the sealing area 12b to ensure the stability of the structure of the sealing area 12b, thereby improving the stability of the overall structure of the inner cylinder 10.

[0078] The plane where the sealing area 12b is located and the plane where the air inlet area 12a is located can be the same plane, or can be convex to the plane where the air inlet area 12a is located. The part of the plane where the sealing area 12b is located that is convex to the plane where the air inlet area 12a is located can be referred to as a convex surface, which can be a smooth surface to avoid damaging the objects to be dried during the operation of the clothes drying device 1000. When the plane where the sealing area 12b is located is convex to the plane where the air inlet area 12a is located, the sealing area 12b can be convex to the side of the first cavity 10a along the axis direction of the inner cylinder 10, can be convex to the side away from the first cavity 10a along the axis direction of the inner cylinder 10, or can be convex to both sides of the inner cylinder bottom wall 12 along the axis direction of the inner cylinder 10, so as to improve the stability of the structure of the sealing area 12b, thereby improving the structural strength of the inner cylinder 10.

[0079] The fourth sealing member 402 can be arranged around the air inlet 121 so that the fourth sealing member 402 and the air inlet 121 are staggered, thereby avoiding that the fourth sealing member 402 blocks the air inlet 121.

[0080] 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 opening 312 communicating with the air outlet 51. The objects to be dried can be put 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 objects to be dried can flow out of the first cavity 10a through the air outlet 51 and the first exhaust opening 312 in sequence.

[0081] Please refer to Figure 6 , Figure 6is a perspective structural schematic view of an embodiment of the inner drum and the second support plate of the clothes drying apparatus provided in the present application.

Specifically, the second support plate 32 has a plurality of ventilation areas 32a and a plurality of support portions 323, and the ventilation areas 32a are arranged at intervals with the support portions 323. Among them, the plurality of ventilation areas 32a correspond to the plurality of air inlet areas 12a on the bottom wall 12 of the inner drum one by one, and the plurality of support portions 323 correspond to the plurality of sealing areas 12b on the bottom wall 12 of the inner drum one by one. Each ventilation area 32a can correspond to one ventilation opening 321, or each ventilation area 32a can correspond to a plurality of ventilation openings 321, and the ventilation openings 321 are arranged corresponding to the air inlets 121. The dry hot air flow outside the inner drum 10 enters the first cavity 10a in turn through the ventilation openings 321 and the air inlets 121.

[0082] The clothes drying apparatus 1000 comprises a shell 80, and the shell 80 comprises a bottom shell 82. The bottom shell 82 is located at the bottom of the clothes drying apparatus 1000, and is arranged on the side of the bottom cover plate 22 away from the inner drum 10, and is sealingly connected or integrally formed with the bottom cover plate 22 to form a third cavity 80a between the bottom shell 82 and the bottom cover plate 22. The sealing connection mode includes but is not limited to riveting, welding or bolt connection and the like. When the bottom shell 82 is integrally formed with the bottom cover plate 22, the bottom shell 82 and the bottom cover plate 22 are an integral whole, which not only simplifies the types and quantities of parts, but also facilitates operation and reduces assembly difficulty during the manufacturing process of the clothes drying apparatus 1000, saves working hours, and makes the assembly more efficient.

[0083] The side of the bottom cover plate 22 away from the inner drum 10 is provided with a fixing plate 224. The fixing plate 224 extends from the bottom cover plate 22 towards the direction away from the inner drum 10. The fixing plate 224 is provided with a mounting hole, and a fixing member is matched with the mounting hole to fix the fixing plate 224 to the second support plate 32, so as to further ensure the structural strength of the outer drum 20. The fixing plate 224 is sealingly connected or integrally formed with the bottom cover plate 22. The integrally formed mode can improve the air tightness of the connection between the fixing plate 224 and the bottom cover plate 22, enhance the structural strength of the fixing plate 224 and the bottom cover plate 22 as a whole, and simplify the number of parts and reduce the structural weight. The sealing connection mode includes but is not limited to riveting, welding or bolt connection and the like, and the sealing connection mode is not limited herein as long as the sealing connection between the fixing plate 224 and the bottom cover plate 22 is maintained.

The filter 314 can be arranged on the first air outlet 312, arranged on the second air outlet 313, or arranged on both the first air outlet 312 and the second air outlet 313, for filtering the lint and other sundries falling during the operation of the drying apparatus 1000, avoiding the air duct 101 between the first air outlet 312 and the second air outlet 313 being blocked and affecting the air exhaust efficiency of the first cavity 10a, and preventing the lint and other sundries from entering the inner circulation cavity 80b through the air inlet 801, the first air outlet 312, the air duct 101, the second air outlet 313, and the air inlet 801 in sequence, thereby avoiding the dehumidification effect of the evaporator 91 and the heating effect of the condenser 92 being affected.

[0093] The clothes drying apparatus 1000 further comprises a cover plate 70 covering the second support plate 32 on a side facing away from the outer drum 20 to form an air supply cavity 70a. The air supply cavity 70a is in communication between the first cavity 10a and the inner circulation cavity 80b. The air supply cavity 70a is in communication with the first cavity 10a through the air vent 321 and the air inlet 121.

[0094] The second support plate 32 is further provided with a second air supply opening 322 corresponding to the first air supply opening 831a. The second air supply opening 322 is entirely located in the air supply cavity 70a formed by the cover plate 70 covering the second support plate 32, so that the inner circulation cavity 80b cannot be in communication with the external environment through the first air supply opening 831a and the second air supply opening 322, thereby ensuring the sealing of the inner circulation cavity 80b.

[0095] The clothes drying apparatus 1000 further comprises an air supply member 93, which can be arranged at the first air supply opening 831a, or at the second air supply opening 322, or across the first air supply opening 831a and the second air supply opening 322, or in the inner circulation cavity 80b, or in the air supply cavity 70a, to send the dry hot air stream after heat exchange by the condenser 92 into the air supply cavity 70a through the first air supply opening 831a and the second air supply opening 322. The air supply member 93 can be a fan.

[0096] In some embodiments, the air supply member 93 sends the dry hot air stream after heat exchange by the condenser 92 from the inner circulation cavity 80b into the air supply cavity 70a through the first air supply opening 831a and the second air supply opening 322, so that the inner circulation cavity 80b is in a negative pressure state, the dry hot air flowing into the air supply cavity 70a flows in the direction from the second air supply opening 322 to the air vent 321, and sequentially passes through the air vent 321 and the air inlet 121 to flow into the first cavity 10a, the dry hot air flows in the first cavity 10a from the drum bottom end 14 of the inner drum 10 to the open end 13, and after heat exchange with the objects to be dried, carries the water vapor of the objects to be dried to flow into the inner circulation cavity 80b through the air outlet 51 on the extension 50, the first air exhaust opening 312 on the first support plate 31, and the air inlet 801 in sequence, thereby realizing the air flow circulation of the first cavity 10a, the inner circulation cavity 80b, and the air supply cavity 70a.

[0097] Please refer to Figure 8 , Figure 8is a schematic diagram of internal air circulation of an embodiment of the drying apparatus provided in the present application, wherein the directions indicated by arrows are the directions of air circulation. The dry hot air 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 under the action of the air supply member 93. After entering the air supply cavity 70a, the dry hot air flows into the first cavity 10a through the air vent 321 and the air inlet 121 in sequence. The dry hot air flows from the air inlet 121 to the air outlet 51 after entering the first cavity 10a, and exchanges heat with the objects to be dried during the process of flowing in the first cavity 10a, forming a low-temperature and high-humidity air flow. The low-temperature and high-humidity air flow flows into the air duct 101 between the first support plate 31 and the front panel 100 through the air outlet 51 on the extension 50 and the first air exhaust port 312 on the first support plate 31 in sequence, and flows in the air duct 101 along the direction from the first air exhaust port 312 to the second air exhaust port 313 on the first support plate 31, and then enters the inner circulation cavity 80b through the second air exhaust port 313 and the air inlet 801 in sequence. The low-temperature and high-humidity air flow entering the inner circulation cavity 80b first contacts the evaporator 91, which dehumidifies and cools the low-temperature and high-humidity air flow. The compressor 94 pressurizes the air flow after dehumidification and cooling by the evaporator 91, forming a high-temperature and high-pressure gas, which then enters the condenser 92, forming a dry hot air flow. The dry hot air flow 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 under the action of the air supply member 93, thereby forming a closed circulation.

[0098] Please refer to Figure 9 , Figure 9 is a schematic diagram of the structure of an embodiment of the support member of the drying apparatus provided in the present application. The drying apparatus 1000 includes two support members 33. In some embodiments, the two support members 33 can be arranged between the first support plate 31 and the outer cylinder 20.

[0099] The two support members 33 can be oppositely arranged on two sides of the inner cylinder 10, and the surface of the support wheel 331 away from the bottom cover plate 22 is in contact with the inner cylinder 10, and the two support members 33 support 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 direction of the inner cylinder 10, and 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 clothes drying device 1000, and improving the energy efficiency of the clothes drying device 1000. The first support shaft 332 can play a sealing role, preventing air flow in the second cavity 20a from flowing out of the mounting hole of the support member 33, and preventing external 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 clothes drying device 1000. The outer wall surface of the support wheel 331 is separated from the outer cylinder 20 by a certain distance, avoiding scratching the outer cylinder 20 during rotation of the support wheel 331.

[0100] By arranging two support members 33, the open end 13 of the inner cylinder 10 is arranged on the two support members 33, so that the center of gravity of the inner cylinder 10 remains stable, which can prevent the inner cylinder 10 from jumping in the radial and axial directions to a certain extent, thereby ensuring stable rotation of the inner cylinder 10.

[0103] In some embodiments, the second support shaft 63 is first inserted into the bearing 61, with both ends of the second support shaft 63 extending beyond the end faces of both ends of the bearing 61, and then one end of the second support shaft 63 is inserted into the first shaft hole 122 in the center of the bottom wall 12 of the inner cylinder, and the second support shaft 63 is arranged in the first shaft hole 122 by a fixing member, and the other end is inserted into the second shaft hole 324 of the second support plate 32 and the third shaft hole 621 of the locking member 62, so that the locking member 62 arranges the second support shaft 63 in the second support plate 32, thereby rotatably supporting the inner cylinder 10 on the second support plate 32, achieving rotatable connection of the inner cylinder 10. The bearing 61 is connected between the second support plate 32 and the inner cylinder 10, which not only supports the inner cylinder 10, but also reduces the friction coefficient during rotation of the inner cylinder 10, limits the radial and axial runout during rotation of the inner cylinder 10, and also reduces the power consumption of the drying appliance 1000.

[0104] The bottom end 14 of the inner cylinder 10 is rotatably arranged on the second support plate 32 by the bearing 61. The open end 13 of the inner cylinder 10 is rotatably arranged on the first support plate 31 by two support members 33. The two support members 33 are arranged on both sides of the open end 13 of the inner cylinder 10. The two support members 33 and the bearing 61 jointly 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, and the structure is more stable.

[0105] The drying appliance 1000 further comprises a door body 110.
