Description

Technical Field

[0001] This invention relates to the field of clothes dryer technology, and more specifically, to a clothes dryer. Background Technology

[0002] Traditional dryers use an air duct housing assembly that defines a ventilation chamber. The clothes handling drum assembly is located on one side of the air duct housing assembly and is rotatably connected to the side wall of the air duct housing assembly. The internal capacity of the clothes handling drum is limited by the space in front of the air duct housing assembly inside the dryer. Furthermore, an opening needs to be made on the side wall of the air duct housing assembly at a position corresponding to the clothes handling drum assembly to connect the internal cavity of the clothes handling drum assembly and the ventilation chamber. As the airflow flows into the internal cavity of the clothes handling drum assembly, it encounters multiple structural obstructions, resulting in high airflow resistance and affecting airflow rate and velocity. There is room for improvement in this regard. Summary of the Invention

[0044] The following is for reference. Figures 1-9 A clothes dryer according to an embodiment of the present invention is described.

[0045] A clothes dryer according to an embodiment of the present invention may include: a clothes dryer according to an embodiment of the present invention, comprising: an air duct housing assembly 1 and a clothes handling drum assembly 2.

[0046] In a traditional dryer, the air duct housing assembly 1 defines a ventilation cavity 101. The clothes handling drum assembly 2 is located on one side of the air duct housing assembly 1 and is rotatably connected to the side wall of the air duct housing assembly 1 on the same side. The inner capacity of the clothes handling drum is limited by the space in front of the air duct housing assembly 1 inside the dryer. Furthermore, a hole 441 needs to be opened on the side wall of the air duct housing assembly 1 at a position corresponding to the clothes handling drum assembly 2 to connect the inner cavity of the clothes handling drum assembly 2 and the ventilation cavity 101. During the process of airflow flowing into the inner cavity of the clothes handling drum assembly 2, it passes through multiple structural obstructions, resulting in high airflow resistance and affecting the airflow rate and velocity.

[0047] To address this, this invention provides an air duct housing assembly 1 that defines a ventilation cavity 101 with an opening 1011 on one side. A clothes handling drum assembly 2 has an air inlet 202 that connects the ventilation cavity 101 and the clothes handling cavity 201. Thus, airflow only needs to pass through the air inlet 202 to enter the clothes handling cavity 201 from the ventilation cavity 101, significantly reducing air resistance during the flow into the clothes handling cavity 201. Furthermore, the clothes handling drum assembly 2 is not connected to the front structure of the air duct housing assembly 1; a portion of the clothes handling drum assembly 2 can extend into the ventilation cavity 101 through the opening 1011. Therefore, the capacity of the clothes handling cavity 201 is no longer limited by the space in front of the air duct housing assembly 1, increasing the capacity of the clothes handling cavity 201.

[0048] Since the support of the garment handling tube assembly 2 needs to rely on a high-strength support structure, the air duct shell assembly 1 is provided with a reinforcing member 4. The garment handling tube assembly 2 is rotatably connected to the reinforcing member 4 so as to support the garment handling tube assembly 2 with the support of the high-strength reinforcing member 4 and ensure the stability of the garment handling tube assembly 2.

[0049] The garment processing drum assembly 2 is rotatably supported on the reinforcing member 4 via a rotating shaft 23. Specifically, one end of the rotating shaft 23 is connected to the garment processing drum assembly 2, and the rotating shaft 23 is rotatably supported on the reinforcing member 4 so that the garment processing drum assembly 2 can rotate relative to the air duct shell assembly 1 to achieve uniform drying of the garments.

[0050] According to an embodiment of the present invention, the clothes dryer has a large capacity of clothes handling chamber 201 and the clothes handling drum assembly 2 can be stably supported on the air duct shell assembly 1, resulting in low production cost.

[0051] Combination Figures 1-9 In the embodiment shown, the air duct shell assembly 1 includes a support plate 12 and an air duct shell 13. An opening 1011 is provided on the support plate 12, and the air duct shell 13 is provided on one side of the support plate 12 in the thickness direction and covers the opening 1011, so that the air duct shell 13 and the support plate 12 can jointly define a ventilation cavity 101 communicating with the opening 1011.

[0052] Among them, the reinforcing member 4 can be connected to the air duct shell 13 so that the air duct shell 13 and the reinforcing frame are connected as one unit. While the reinforcing member 4 strengthens the strength of the air duct shell 13, the air duct shell 13 can also stably support the reinforcing member 4, making the reinforcing frame stronger and better supporting the clothing processing tube assembly 2.

[0053] The reinforcing frame can also be connected to the support plate 12 to enhance the strength of the reinforcing member 4 by relying on the high-strength support plate 12 structure, so that the reinforcing member 4 can more stably support the clothing handling tube assembly 2 and ensure the support stability of the clothing handling tube assembly 2.

[0054] The reinforcing member 4 can also be connected to the air duct shell 13 and the support plate 12 at the same time. Thus, the support plate 12, the air duct shell 13 and the reinforcing member 4 are stably connected as one, the overall structure is stable, the air duct shell assembly 1 has higher overall strength, which is beneficial for supporting the clothing processing tube assembly 2.

[0055] Reference Figures 1-3 The reinforcing member 4 has a mounting part 41 and multiple connecting parts 42. The mounting part 41 is used to connect with the rotating shaft 23. The connecting parts 42 are used to fix the reinforcing member 4 as a whole on the air duct shell assembly 1 and to strengthen the structure of the mounting part 41, ensuring the strength of the mounting part 41, ensuring that the mounting part 41 can stably support the clothing handling tube assembly 2, and ensuring the stability of the clothing handling tube assembly 2 connected with the mounting part 41.

[0056] Specifically, the mounting part 41 is disposed opposite to the port 1011 and the rotating shaft 23 is rotatably supported on the mounting part 41, and a plurality of connecting parts 42 are located on the outer periphery of the port 1011 and connected to the air duct shell 13 and / or the support plate 12.

[0057] When the connecting part 42 is connected to the air duct shell 13, the structural strength of the air duct shell 13 at the relative position of the opening 1011 is low, and it cannot stably support the mounting part 41 and the clothes handling tube assembly 2. Therefore, the connecting part 42 is located on the outer periphery of the opening 1011, so that the connecting part 42 can be connected to the air duct shell 13 corresponding to the outer periphery of the opening 1011. The distance between the connection point of the connecting part 42 and the air duct shell 13 and the connection point of the air duct shell 13 and the support plate 12 is closer, so that the reinforcing member 4 and the clothes handling tube assembly 2 can be stably and indirectly fixed to the support plate 12 through the air duct shell 13, reducing the stress on the air duct shell 13, and relying on the high-strength support plate 12, the strength of the reinforcing plate is strengthened, so that the reinforcing member 4 stably supports the clothes handling tube assembly 2, ensuring the stability of the clothes handling tube assembly 2.

[0058] Alternatively, the connecting part 42 can be directly connected to the support plate 12 on the outer periphery of the opening 1011, so as to strengthen the strength of the reinforcing plate by relying on the high-strength support plate 12, so that the reinforcing member 4 can stably support the clothing handling tube assembly 2 and ensure the stability of the clothing handling tube assembly 2.

[0059] Multiple connecting parts 42 are located on the outer periphery of the opening 1011. That is, the connecting parts 42 are close to or attached to the air duct shell 13, which can also achieve space avoidance. This prevents the connecting parts 42 from occupying the ventilation space in the ventilation cavity 101 or the installation space behind the air duct shell 13, and prevents the setting of the reinforcing member 4 from affecting the air resistance in the ventilation cavity 101 or the installation of other internal structures of the dryer, thereby achieving the miniaturization and weight reduction of the dryer.

[0060] like Figures 1-5 As shown, the reinforcing member 4 forms a reinforcing plate to reduce the space occupied by the reinforcing member 4 in the thickness direction of the support plate 12 inside the dryer, thereby reducing the axial dimension of the clothes handling drum assembly 2 of the dryer, which is beneficial to the miniaturization and weight reduction of the dryer. The mounting part 41 is located in the middle of the reinforcing plate in the length direction, and the two ends of the reinforcing plate in the length direction have connecting parts 42, that is, the two sides of the reinforcing plate in the length direction are connected to the support plate 12 or the air duct shell 13. By setting the mounting part 41, which bears the weight of the clothes handling drum assembly 2, in the middle of the reinforcing plate in the length direction, the connecting parts 42 at both ends of the reinforcing plate in the length direction can be evenly stressed, ensuring the stability of the reinforcing plate.

[0061] Reference Figure 3 The length of the reinforcing plate extends horizontally so that the extension direction of the reinforcing plate is perpendicular to the direction of gravity, so as to avoid the force on the reinforcing plate being concentrated on one side of the reinforcing plate, that is, the force on one side of the connecting part 42 is relatively small, which affects the stability of the reinforcing plate and may even cause the reinforcing plate to deform under stress.

[0062] like Figures 1-3As shown, the reinforcing plate has at least one reinforcing portion 43, which strengthens the structure of the reinforcing plate itself, ensuring that the reinforcing plate has sufficient strength to support the clothing handling tube assembly 2 and preventing deformation of the reinforcing plate under stress, thus ensuring the stability of the reinforcing plate. The reinforcing portion 43 extends along the length direction of the reinforcing plate so that it can uniformly strengthen all parts of the reinforcing plate along its length, avoiding stress concentration.

[0063] The reinforcing part 43 includes at least one of a reinforcing recess and a reinforcing protrusion. By reinforcing the recess or the protrusion, the overall strength of the reinforcing plate can be improved, and the production cost of the reinforcing plate is minimally affected. The reinforcing plate can be integrally stamped.

[0064] Among them, such as Figure 1 and Figure 2 As shown, at least a portion of the reinforcing part 43 extends circumferentially along the mounting part 41 to reinforce the connection between the reinforcing plate and the clothing handling tube assembly 2, ensuring the strength of the connection between the clothing handling tube assembly 2 and the reinforcing plate, thereby enabling the reinforcing plate to better support the clothing handling tube assembly 2.

[0065] Combination Figures 1-3 In the embodiment shown, the duct shell 13 is provided with a plurality of connection holes 133, and the support plate 12 is provided with a plurality of mating holes 122. The positions of the plurality of connection holes 133 and the plurality of mating holes 122 correspond one-to-one. The support plate 12 and the duct shell 13 are connected by a plurality of fasteners 14, and each fastener 14 passes through the corresponding connection hole 133 and mating hole 122. Thus, by the fasteners 14 passing through the connection hole 133 and the mating hole 122, the support plate 12 and the duct shell 13 can be stably mated and connected together, and the airtightness of the ventilation cavity 101 is ensured.

[0066] The reinforcing member 4 is located between two adjacent fasteners 14 to avoid the fasteners 14 used to connect the support plate 12 and the air duct shell 13. On the one hand, the setting of the reinforcing member 4 avoids affecting the installation of the fasteners 14 and ensures that the fasteners 14 have sufficient installation space. On the other hand, it avoids the vibration of the reinforcing member 4 during the operation of the clothing handling tube assembly 2, which affects the connection stability of the fasteners 14 and ensures that the fasteners 14 are set stably and that the air duct shell 13 and the support plate 12 can be stably sealed.

[0067] There are at least three possible installation methods for the reinforcing member 4. The reinforcing member 4 is located on the side of the air duct shell 13 facing away from the opening 1011 and is at least connected to the support plate 12. Thus, the reinforcing member 4 is located outside the ventilation cavity 101 and on the side of the air duct shell 13 facing away from the opening 1011. The clothing handling tube assembly 2 is rotatably connected to the reinforcing member 4 via a rotating shaft 23. The rotating shaft 23 needs to pass through the air duct shell 13 and connect to the reinforcing member 4 located outside the ventilation cavity 101.

[0068] Alternatively, the reinforcing member 4 is connected to the side of the duct housing 13 facing the opening 1011 and located between the duct housing 13 and the support plate 12. The clothing handling tube assembly 2 is rotatably connected to the reinforcing member 4 via a rotating shaft 23. That is, the reinforcing member 4 is located inside the ventilation cavity 101, and the rotating shaft 23 can be directly connected to the reinforcing member 4 located inside the ventilation cavity 101. The reinforcing member 4 is connected to the duct housing 13.

[0069] Alternatively, the reinforcing member 4 is connected to the side of the support plate 12 facing the air duct shell 13. The air duct shell 13 covers the reinforcing member 4 so that the reinforcing member 4 is located between the air duct shell 13 and the support plate 12. The garment handling tube assembly 2 is rotatably connected to the reinforcing member 4 via a pivot 23. That is, the reinforcing member 4 is located inside the ventilation cavity 101, and the pivot 23 can be directly connected to the reinforcing member 4 located inside the ventilation cavity 101. The reinforcing member 4 is connected to the support plate 12 so that the high-strength support plate 12 can strengthen the reinforcing member 4 and ensure the stability of the reinforcing member 4 in supporting the garment handling tube assembly 2.

[0070] Reference Figures 1-3 The reinforcing member 4 is at least partially bent to match the inner or outer surface of the air duct shell 13. Thus, the reinforcing member 4 and the air duct shell 13 can be fitted together to simultaneously enhance the strength of both the reinforcing member 4 and the air duct shell 13, resulting in a higher overall structural strength and more stable structure of the dryer. At the same time, fitting the reinforcing member 4 to the air duct shell 13 also avoids the reinforcing member 4 occupying more space inside the dryer, ensuring the utilization rate of the internal space of the dryer and ensuring the miniaturization and lightweight of the dryer.

[0071] like Figure 4 and Figure 5 As shown, the dryer also includes: a bearing housing 111, on which a bearing 112 is mounted, and a rotating shaft 23 is rotatably supported on the reinforcing member 4 in cooperation with the bearing 112. The bearing housing 111 is used to mount the bearing 112, which includes an outer bearing and an inner bearing. The outer bearing is fixed on the bearing housing 111, and the inner bearing is fixedly connected to the rotating shaft 23. The clothes handling drum assembly 2 is rotatably supported on the reinforcing member 4 via the bearing 112.

[0072] By molding the bearing housing 111 and the reinforcing member 4 separately, and then assembling the bearing housing 111 onto the reinforcing member 4 by welding or fastener 14, the production difficulty of the reinforcing member 4 and the bearing housing 111 can be reduced, thereby reducing the production cost of the dryer.

[0073] In other embodiments, the bearing housing 111 may be integrally formed with the reinforcing member 4 to make the connection between the reinforcing member 4 and the bearing housing 111 more stable.

[0074] The bearing housing 111 is arranged opposite to the port 1011 so that the bearing housing 111 and the bearing 112 provided on the bearing housing 111 can be located at the position where the axis of the clothing handling tube assembly 2 intersects with the reinforcing member 4, so that the clothing handling tube assembly 2 can rotate stably around its own axis, ensuring the stability of the clothing handling tube assembly 2.

[0075] Reference Figure 4 and Figure 5 The reinforcing member 4 extends towards the direction of the clothes handling drum assembly 2, forming a mounting recess 44 on the side of the reinforcing member 4 facing away from the clothes handling drum assembly 2. The bearing seat 111 is at least partially disposed in the mounting recess 44. The opening of the mounting recess 44 can provide space for the installation of the bearing seat 111 and the bearing 112, and can also increase the mating area between the reinforcing member 4 and the bearing seat 111, making the installation of the bearing seat 111 more stable. Furthermore, it can also prevent the installation of the bearing seat 111 or the bearing 112 from increasing the axial dimensions of the air duct housing assembly 1 and the reinforcing member 4 in the clothes handling drum assembly 2, thereby preventing the installation of the bearing seat 111 from affecting the overall size of the dryer in the axial direction of the clothes handling drum assembly 2, and realizing the miniaturization and weight reduction of the dryer.

[0076] The bearing housing 111 is disposed within the mounting recess 44. The inner wall of the mounting recess 44 can limit the bearing housing 111, ensuring the stability of the bearing housing 111. The shape of the bearing housing 111 is adapted to the shape of the mounting recess 44 so that the bearing housing 111 can be completely embedded in the mounting recess 44. The inner wall of the mounting recess 44 limits the bearing housing 111, ensuring the stability of the bearing housing 111. In addition, it can also prevent the mounting recess 44 from occupying too much space and affecting the ventilation space inside the ventilation cavity 101, reducing the impact of the mounting recess 44 on the air resistance inside the ventilation cavity 101.

[0077] The mounting recess 44 is located on the side of the reinforcing member 4 facing away from the clothing handling tube assembly 2. This allows the bearing housing 111 to be located outside the ventilation cavity 101 as much as possible, so that the bearing 112 and the bearing housing 111 do not need to directly contact the airflow in the ventilation cavity 101. This avoids water vapor in the airflow from corroding the bearing 112 or the bearing housing 111 and affecting the service life of the bearing 112 and the bearing housing 111.

[0078] Furthermore, the bottom wall of the mounting recess 44 is provided with an opening 441 to allow the rotating shaft 23 or bearing seat 111 to pass through, so as to connect the bearing seat 111 located on the rear side of the reinforcing member 4 and the clothing handling tube assembly 2 located on the front side of the reinforcing member 4.

[0079] like Figure 4 and Figure 5As shown, the bearing housing 111 includes a first housing body 1111 and a second housing body 1112. The first housing body 1111 and the second housing body 1112 are arranged opposite to each other and define an installation space. The installation space provides space for the installation of the bearing 112. The bearing 112 is a rolling bearing 112 and is located in the installation space. The rolling bearing 112 includes an outer bearing 112 and an inner bearing 112. The outer bearing 112 is fixedly installed in the installation space, and the inner bearing 112 is fixedly connected to the rotating shaft 23. The first housing body 1111 and the second housing body 1112 stop on opposite sides of the outer ring of the rolling bearing 112. That is, the first housing body 1111 and the second housing body 1112 limit the bearing 112 on both sides of the bearing 112 axially to ensure the stability of the bearing 112 installation. The rotating shaft 23 is provided with a limiting step 231, which stops on one side of the inner ring of the rolling bearing 112 to prevent the rotating shaft 23 from moving axially relative to the rolling bearing 112 and affecting the stability of the connection of the rotating shaft 23. The inner bearing 112 of the inner ring of the rolling bearing 112 is fixedly connected to the rotating shaft 23 by an interference fit, so that the rotating shaft 23 and the clothing handling tube assembly 2 connected to the rotating shaft 23 can rotate relative to the air duct housing assembly 1.

[0080] Reference Figure 4 The reinforcing member 4 is located on the outside of the ventilation cavity 101, that is, the reinforcing member 4 is located on the side of the air duct shell 13 facing away from the opening 1011, so as to avoid the arrangement of the reinforcing member 4 affecting the arrangement of the internal structure of the ventilation cavity 101 and to avoid the arrangement of the reinforcing member 4 affecting the sealing of the ventilation cavity 101.

[0081] Among them, the reinforcing member 4 has a mounting protrusion 45 on the side facing the clothing handling drum assembly 2, which corresponds to the position of the mounting recess 44. Since the reinforcing member 4 is fitted on the air duct shell 13, the structure of the part of the air duct shell 13 corresponding to the mounting protrusion 45 should be arranged to avoid the mounting protrusion 45. Therefore, the air duct shell 13 is provided with a clearance hole 134 to avoid structural redundancy at the position of the air duct shell 13 corresponding to the mounting protrusion 45, which would affect the axial size of the clothing handling drum assembly 2 of the air duct shell assembly 1. The mounting protrusion 45 is inserted into the clearance hole 134, and the mounting protrusion 45 can seal the clearance hole 134. In addition, the clearance hole 134 can also allow the rotating shaft 23 or the bearing seat 111 to pass through. The bearing 112 provided in the mounting recess 44 can pass through the bottom wall opening 441 of the mounting recess 44 and directly connect to the clothing handling drum assembly.

[0082] In other embodiments, the reinforcing member 4 is disposed within the ventilation cavity 101, that is, the reinforcing member 4 is located between the air duct shell 13 and the support plate 12. Optionally, the reinforcing member 4 may be spaced apart from the air duct shell 13, or the reinforcing member 4 may be fitted to the air duct shell 13. When the reinforcing member 4 is fitted to the air duct shell 13, the strength of the reinforcing member 4 and the air duct shell 13 is improved, and the axial dimension of the air duct shell assembly 1 in the clothing handling tube assembly 2 is smaller.

[0083] The bearing housing 111 is at least partially disposed between the air duct shell 13 and the reinforcing member 4, so that the air duct shell 13 and the reinforcing member 4 can jointly protect the bearing housing 111 and the bearing 112 disposed on the bearing housing 111, ensuring the stability of the bearing housing 111 and the bearing 112. In some embodiments, the reinforcing member 4 and the air duct shell 13 define a closed installation space for the bearing housing 111. The bearing housing 111 is disposed in the installation space to avoid it from being corroded by the external environment and to improve its service life.

[0084] In some embodiments, the duct housing 13 is an integral injection molded part to reduce the weight of the duct housing 13. The duct housing assembly 1 is integrally molded, which simplifies the installation steps and ensures the sealing of the ventilation cavity 101.

[0085] Alternatively, in other embodiments, the duct shell 13 includes at least two separately formed structural components. The two separately formed structural components work together with the support plate 12 to define the structure of the ventilation cavity 101. Dividing the duct shell 13 into two separately formed structural components helps to simplify the manufacturing process of the duct shell 13, and the two structural components can be made of different materials according to requirements, thus saving production costs.

[0086] Furthermore, the reinforcing member 4 is a metal part, so as to utilize the high strength of the metal part to ensure the strength of the reinforcing member 4, thereby ensuring the stability of the clothing handling tube assembly 2 supported on the reinforcing member 4.

[0087] The capacity of the clothing processing chamber 201 in a traditional dryer is limited by the space in front of the internal air duct shell assembly 1 of the dryer. Furthermore, the airflow passes through multiple obstructions during its flow into the clothing processing chamber 201, resulting in high airflow resistance and affecting airflow rate and velocity.

[0088] In this embodiment of the invention, a portion of the garment handling tube assembly 2 extends into the ventilation cavity 101 through the opening 1011, and an air inlet 202 is provided on this portion of the structure. The air inlet 202 connects the ventilation cavity 101 and the garment handling cavity 201. Thus, the airflow only needs to pass through the air inlet 202 to enter the garment handling cavity 201 from the ventilation cavity 101, which greatly reduces the wind resistance during the flow of air into the garment handling cavity 201. Furthermore, since a portion of the structure of the garment handling tube assembly 2 can extend into the ventilation cavity 101 through the opening 1011, the capacity of the garment handling cavity 201 is no longer limited by the space in front of the air duct shell assembly 1, thereby increasing the capacity of the garment handling cavity 201.

[0089] Reference Figure 1 and Figure 9The support plate 12 also has an air vent 1012 located on one side of the opening 1011. The air vent 1012 can deliver airflow into the ventilation cavity 101. The airflow enters the ventilation cavity 101 through the air vent 1012, and then enters the garment processing cavity 201 through the opening 1011 to participate in garment processing. The ventilation cavity 101 is provided with a fan wheel arranged opposite to the air vent 1012 to drive the airflow to circulate within the ventilation cavity 101 and the garment processing cavity 201.

[0090] According to some embodiments of the present invention, the dryer further includes a mounting base, which defines an air duct to connect the clothes handling chamber 201 and the ventilation chamber 101. A heating element is provided in the air duct. During operation of the dryer, the humid and cold airflow in the clothes handling chamber 201 passes through the air duct defined by the mounting base, is heated and dehumidified in the air duct, passes through the air outlet 1012, and enters the ventilation chamber 101 defined by the air duct shell assembly 1 under the drive of the impeller. The dry and hot airflow in the ventilation chamber 101 then enters the clothes handling chamber 201 through the air inlet 202 of the clothes handling drum assembly 2 to dry the clothes.

[0091] According to some embodiments of the present invention, the dryer further includes a heat pump system, which includes an evaporator, a condenser, and a compressor, and the heating element includes the evaporator and the condenser. Inside the clothing processing chamber 201, hot, dry air passes through the wet clothes; the residual moisture on the clothes absorbs heat, turning the air into humid, hot air. The humid, hot air enters the air duct, and after passing through the condenser, it is transformed into dry, cold air, with water vapor in the air condensing into water droplets and being discharged. At this time, the dry, cold air continues to be heated and pressurized by the compressor and the evaporator.

[0092] A specific embodiment of the dryer of the present invention is described below with reference to the illustrations.

[0093] like Figures 1-9 As shown, the dryer includes a mounting base, a heat pump system, an air duct housing assembly 1, and a clothes handling drum assembly 2.

[0094] The clothes handling drum assembly 2 defines a clothes handling chamber 201, which is used to hold clothes to be processed. The capacity of the clothes handling chamber 201 affects the number of clothes the dryer can process at the same time and the size of clothes that the dryer can handle. To improve the user experience, the volume of the clothes handling chamber 201 should be as large as possible. The air duct shell assembly 1 defines a ventilation chamber 101, through which the dryer can deliver high-temperature airflow into the clothes handling chamber 201 to achieve the drying function.

[0095] The air duct housing assembly 1 has an opening 1011 on one side. A portion of the clothes handling drum assembly 2 extends into the ventilation cavity 101 through the opening 1011. Thus, the clothes handling drum assembly 2 can extend backward until it reaches into the ventilation cavity 101. This allows the clothes handling drum assembly 2 to be designed to be deeper without changing the external dimensions of the dryer, thereby increasing the capacity of the clothes handling cavity 201. The dryer can handle more and larger clothes at the same time, improving the user experience.

[0096] The clothes handling drum assembly 2 has an air inlet 202, which can directly connect to the ventilation chamber 101 and the clothes handling chamber 201. That is to say, during the airflow process, the airflow in the ventilation chamber 101 can directly enter the clothes handling chamber 201 through the air inlet 202. Based on this, the originally complex air outlet area on the air duct shell assembly 1 can be directly opened into a larger opening 1011, reducing the production cost of the dryer.

[0097] The garment handling tube assembly 2 is provided with a rotating shaft 23, that is, one end of the rotating shaft 23 is fixedly connected to the garment handling tube assembly 2, and the garment handling tube assembly 2 is rotatably supported on the air duct shell assembly 1 through the rotating shaft 23. Therefore, the other end of the rotating shaft 23 is rotatably supported on the air duct shell assembly 1.

[0098] The air duct shell assembly 1 includes a support plate 12 and an air duct shell 13. An opening 1011 is provided on the support plate 12, and the air duct shell 13 is provided on one side of the support plate 12 in the thickness direction and covers the opening 1011. The air duct shell 13 and the support plate 12 together define a ventilation cavity 101.

[0099] The clothes handling drum assembly 2 includes a drum body 211 and an air inlet hood 22. One axial end of the drum body 211 has a clothes loading / unloading port, and the other axial end has an open opening. The clothes loading / unloading port faces the front of the dryer, allowing the user to load clothes into the clothes handling chamber 201. The open opening faces the rear of the dryer, allowing airflow to enter the chamber defined by the drum body 211 for drying the clothes. The chamber defined by the drum body 211 is the main part of the clothes handling chamber 201 used to hold the clothes. The air inlet hood 22 covers the open opening to jointly define the clothes handling chamber 201 with the drum body 211. The air inlet hood 22 serves two purposes: firstly, it separates the ventilation chamber 101 from the clothes handling chamber 201, preventing clothes from entering the ventilation chamber 101 through the open opening; secondly, it provides an installation position for the rotating shaft 23, ensuring stable support for the entire clothes handling drum assembly 2.

[0100] The air inlet hood 22 defines another part of the cavity within the clothing processing chamber 201, which can increase the capacity of the clothing processing chamber 201 and improve the user experience.

[0101] At least a portion of the air inlet hood 22 extends into the ventilation cavity 101 from the opening 1011, allowing the garment processing cavity 201 to extend into the ventilation cavity 101. This utilizes a portion of the space within the ventilation cavity 101 to increase the depth and capacity of the garment processing cavity 201. The air inlet section 202 is arranged around the rotating shaft 23 to ensure the strength of the connection between the rotating shaft 23 and the air inlet hood 22, preventing the air inlet section 202 from affecting the connection between the rotating shaft 23 and the air inlet hood 22, and also preventing the rotating shaft 23 from affecting the air inlet area of ​​the air inlet section 202, thus ensuring the air intake volume of the air inlet section 202.

[0102] The middle part of the air inlet hood 22 extends towards the direction of the clothes loading and unloading port to form a receiving recess 221 on the outer surface of the air inlet hood 22. The rotating shaft 23 is located on the bottom wall of the receiving recess 221 and protrudes from the plane where the opening of the receiving recess 221 is located. The opening of the receiving recess 221 can provide installation space for the rotating shaft 23 and the connection structure between the rotating shaft 23 and the air inlet hood 22, avoiding interference with the rear structure and affecting the normal operation and rotation of the clothes handling drum assembly 2. It can also prevent the setting of the rotating shaft 23 and the connection structure between the rotating shaft 23 and the air inlet hood 22 from increasing the axial dimension of the clothes handling drum assembly 2 and affecting the overall volume of the dryer.

[0103] The rotating shaft 23 protrudes from the plane where the opening of the receiving recess 221 is located, so as to be rotatably connected to the structure of the air duct shell assembly 1 located behind the clothing handling tube assembly 2, so that the entire clothing handling tube assembly 2 can be supported and mounted on the air duct shell assembly 1.

[0104] The recess 221 is located on the outer surface of the air inlet cover 22, which can prevent the setting of the rotating shaft 23 from affecting the flatness of the clothing processing cavity 201, and prevent the setting of the rotating shaft 23 and other structures from increasing the sharp edges in the clothing processing cavity 201, causing damage to the clothing.

[0105] In some embodiments, the connection structure between the air duct housing assembly 1 and the rotating shaft 23 is located on the rear side of the receiving recess 221. By providing the receiving recess 221, installation space can be reserved for the connection structure between the air duct housing assembly 1 and the rotating shaft 23, making the internal space distribution of the dryer more reasonable.

[0106] The air inlet hood 22 has a second extension 224 and a first extension 223 extending in a direction away from the cylinder 211. The first extension 223 extends into the ventilation cavity 101 and defines a first chamber 2011. The first extension 223 and the first chamber 2011 defined by the first extension 223 can increase the capacity of the clothing processing cavity 201. The rotating shaft 23 is provided on the first extension 223 so that the rotating shaft 23 can be located at the center of the clothing processing cylinder assembly 2.

[0107] The second extension 224 has a non-perforated structure and defines the second chamber 2012. The second extension 224 can separate the clothes handling tube assembly 2 from the air duct shell assembly 1, so as to avoid interference between the clothes handling tube assembly 2 and the air duct shell assembly 1 during the rotation.

[0108] The second extension 224 is located between the first extension 223 and the cylinder 211, and the first extension 223 extends away from the cylinder 211 relative to the second extension 224. The garment processing chamber 201 includes a first chamber 2011, a second chamber 2012 and an inner cavity defined by the cylinder 211. In the axial direction of the cylinder 211, the second chamber 2012 connects between the first chamber 2011 and the inner cavity of the cylinder 211. Thus, the airflow flows sequentially through the inner cavities of the first chamber, the second chamber and the cylinder 211, ensuring uniform airflow in the garment processing chamber 201.

[0109] The first extension 223 includes an end wall disposed opposite to the clothing loading and unloading port and a peripheral wall surrounding the end wall. An air inlet 202 is disposed on the end wall and / or the peripheral wall of the first extension 223. A rotating shaft 23 is disposed on the end wall of the first extension 223.

[0110] The end wall of the first extension 223 is further provided with a structural reinforcement 43. At least a portion of the structural reinforcement 43 extends circumferentially along the shaft 23 to reinforce the end wall structure of the garment handling tube assembly 2 for connection with the shaft 23, thereby ensuring the stability of the garment handling tube assembly 2.

[0111] The first extension 223 is provided with an air inlet 202 communicating with the garment processing chamber 201. Airflow can enter the garment processing chamber 201 through the air inlet 202 on the first extension 223. The air inlet 202 includes multiple air inlets, which are spaced apart on the peripheral and end walls of the first extension 223. Thus, the air inlets are evenly distributed on the first extension 223, which on the one hand ensures that the weight of the garment processing tube assembly 2 is uniform in all directions, ensuring that the garment processing tube assembly 2 can rotate stably; on the other hand, during the rotation of the garment processing tube assembly 2, the airflow can stably enter the garment processing chamber 201 through the evenly arranged air inlets, ensuring the stability of the airflow in the garment processing chamber 201.

[0112] The end wall of the first extension 223 is connected to the peripheral wall of the first extension 223 by a circular arc transition. When the airflow passes through the connection between the end wall of the first extension 223 and the peripheral wall of the first extension 223, it can be smoothly guided by the circular arc transition section. This avoids the large resistance when the airflow passes through the bend, which would impact the structure of the first extension 223 and cause noise. It also avoids airflow loss and reduces the difficulty of punching in the production process.

[0113] like Figure 9As shown, the opening 1011 is circular in shape to correspond to the shape of the first extension 223 that extends into the ventilation cavity 101, so that the first extension 223 can be made as large as possible.

[0114] Furthermore, since the opening 1011 is connected to the ventilation cavity 101, the airflow in the ventilation cavity 101 can flow out through the opening 1011. When the diameter of the outer peripheral wall of the cylinder 211 is smaller than the diameter of the opening 1011, the airflow will flow out through the gap between the edge of the opening 1011 and the outer peripheral wall of the cylinder 211, resulting in airflow loss. Therefore, the diameter of the outer peripheral wall of the cylinder 211 is larger than the diameter of the opening 1011.

[0115] Because the garment handling tube assembly 2 is prone to collision with the edge of the opening 1011 during installation, and the edge of the opening 1011 has low strength and sharp edges, which could affect the safety of the installation process, a protective structure 121 is provided at the edge of the opening 1011. Figure 7 As shown, the protective structure 121 can, on the one hand, prevent the edge of the opening 1011 from being too sharp and affecting the safety during the installation process, and on the other hand, improve the strength of the air duct shell assembly 1 at the edge of the opening 1011, and prevent the edge of the opening 1011 from deforming when it is affected by external force.

[0116] The protective structure 121 can be a flanged structure or a rolled edge structure.

[0117] In some embodiments, the air duct housing assembly 1 further has an air outlet 1012 located on one side of the through-hole 1011. A fan is disposed within the ventilation cavity 101 opposite to the air outlet 1012. The dryer also includes a mounting base that defines an air duct to connect the clothes processing cavity 201 and the ventilation cavity 101. A heating element is disposed within the air duct. During operation, the humid and cold airflow in the clothes processing cavity 201 passes through the air duct defined by the mounting base, where it is heated and dehumidified. It then passes through the air outlet 1012 and, driven by the fan, enters the ventilation cavity 101 defined by the air duct housing assembly 1. The dry and hot airflow in the ventilation cavity 101 then enters the clothes processing cavity 201 through the air inlet 202 of the clothes processing drum assembly 2 to dry the clothes.

[0118] According to some embodiments of the present invention, the dryer further includes a heat pump system, which includes an evaporator, a condenser, and a compressor, and the heating element includes the evaporator and the condenser. Inside the clothing processing chamber 201, hot, dry air passes through the wet clothes; the residual moisture on the clothes absorbs heat, turning the air into humid, hot air. The humid, hot air enters the air duct, and after passing through the condenser, it is transformed into dry, cold air, with water vapor in the air condensing into water droplets and being discharged. At this time, the dry, cold air continues to be heated and pressurized by the compressor and the evaporator.

[0119] Furthermore, the air inlet hood 22 is a single piece. During the operation of the dryer, in order to ensure that the clothes handling drum assembly 2 can rotate stably, there is a gap between the air duct shell assembly 1 and the clothes handling drum assembly 2. Airflow will flow out through the gap, causing air volume loss. Therefore, a sealing ring 3 is provided between the air inlet hood 22 and the air duct shell assembly 1, and the sealing ring 3 surrounds the outside of the opening 1011, that is, it also surrounds the outside of the air inlet 202, so as to achieve a seal between the air duct shell assembly 1 and the clothes handling drum assembly 2.

[0120] Furthermore, since the air inlet shroud 22 is rotatable relative to the air duct shell assembly 1, in order to fix the sealing ring 3 and prevent the sealing ring 3 structure from falling off and deforming during the rotation of the air inlet shroud 22 relative to the air duct shell assembly 1, the sealing ring 3 is fixed on one of the air inlet shroud 22 and the air duct shell assembly 1, and the other is movably engaged with the sealing ring 3.

[0121] Reference Figures 7-9 The protective structure 121 includes a limiting flange. Specifically, the edge of the opening 1011 has a limiting flange extending toward the cylinder 211. The sealing ring 3 is sleeved on the outside of the limiting flange. In other words, the limiting flange can limit the sealing ring 3, providing an installation position for the sealing ring 3 and preventing the sealing ring 3 from moving around and affecting the sealing performance.

[0122] Furthermore, the limiting flange is also a protective structure 121 located on the edge of the opening 1011, making the limiting flange more practical.

[0123] The air duct housing assembly 1 is provided with a bearing seat 111 opposite to the port 1011. A bearing 112 is installed on the bearing seat 111. The rotating shaft 23 cooperates with the bearing 112 so that the clothes handling drum assembly is rotatably supported on the air duct housing assembly 1. Thus, the rotating shaft 23 can be rotatably connected to the bearing seat 111 through the bearing 112, thereby making the rotating shaft 23 rotatably connected to the air duct housing assembly 1. The clothes handling drum assembly 2 is rotatably supported on the air duct housing assembly 1.

[0124] The clothes handling drum assembly 2 has a receiving recess 221 that opens toward the bearing seat 111. The rotating shaft 23 is located on the bottom wall of the receiving recess 221. The opening of the receiving recess 221 provides installation space for the rotating shaft 23 and the connection structure between the rotating shaft 23 and the air inlet cover 22, avoiding interference with the rear air duct shell assembly 1, the bearing seat 111 and the installation structure of the bearing seat 111, which would affect the normal operation and rotation of the clothes handling drum assembly 2. It also avoids increasing the axial dimension of the clothes handling drum assembly 2 and affecting the overall volume of the dryer.

[0125] The connection part 42 between the air duct housing assembly 1 and the rotating shaft 23 and the bearing seat 111 are located on the rear side of the receiving recess 221. By setting the receiving recess 221, installation space can be reserved for the connection part 42 between the air duct housing assembly 1 and the rotating shaft 23 and the bearing seat 111, making the internal space distribution of the dryer more reasonable.

[0126] The bearing housing 111 extends at least partially into the receiving recess 221 from the opening of the receiving recess 221 so that the bearing 112 can engage with the rotating shaft 23, and can shorten the distance between the bearing housing 111 and the connection position between the garment handling tube assembly 2 and the rotating shaft 23, thereby reducing the stress on the rotating shaft 23.

[0127] The bearing housing 111 includes a first housing body 1111 and a second housing body 1112. The first housing body 1111 and the second housing body 1112 are arranged opposite to each other and define an installation space. The installation space provides space for the installation of the bearing 112. The bearing 112 is a rolling bearing 112 and is located in the installation space. The rolling bearing 112 includes an outer bearing 112 and an inner bearing 112. The outer bearing 112 is fixedly installed in the installation space, and the inner bearing 112 is fixedly connected to the rotating shaft 23. The first housing body 1111 and the second housing body 1112 stop on opposite sides of the outer ring of the rolling bearing 112. That is, the first housing body 1111 and the second housing body 1112 limit the bearing 112 on both sides of the bearing 112 axially to ensure the stability of the bearing 112. The rotating shaft 23 is provided with a limiting step 231, which stops on one side of the inner ring of the rolling bearing 112 to prevent the rotating shaft 23 from moving axially relative to the rolling bearing 112 and affecting the stability of the connection of the rotating shaft 23. The inner bearing 112 of the inner ring of the rolling bearing 112 is fixedly connected to the rotating shaft 23 by an interference fit, so that the rotating shaft 23 and the clothing handling tube assembly 2 connected to the rotating shaft 23 can rotate relative to the air duct housing assembly 1.

[0128] In some embodiments, combined with Figures 1-6 In the embodiment shown, the air duct shell assembly 1 further includes a reinforcing member 4, and the clothing handling tube assembly 2 is rotatably connected to the reinforcing member 4 so as to achieve stable support of the clothing handling tube assembly 2 by relying on the high-strength reinforcing member 4. The reinforcing member 4 has a mounting part 41 and a connecting part 42. The reinforcing member 4 is used to support the clothing handling tube assembly 2 and ensure the stability of the clothing handling tube assembly 2.

[0129] The garment processing drum assembly 2 is connected to the reinforcing member 4 via a rotating shaft 23. Specifically, one end of the garment processing drum assembly 2 is provided with a rotating shaft 23, which is rotatably supported on the reinforcing member 4 so that the garment processing drum assembly 2 can rotate relative to the air duct shell assembly 1 to achieve uniform drying of the garments.

[0130] The reinforcing member 4 forms a reinforcing plate to reduce the space occupied by the reinforcing member 4 in the thickness direction of the support plate 12 inside the dryer. The mounting part 41 is located in the middle of the length direction of the reinforcing plate, and the two ends of the length direction of the reinforcing plate have connecting parts 42. That is, the two sides of the length direction of the reinforcing plate are connected to the support plate 12 or the air duct shell 13. By setting the mounting part 41, which bears the weight of the clothes handling drum assembly 2, in the middle of the length direction of the reinforcing plate, the connecting parts 42 at both ends of the length direction of the reinforcing plate can be evenly stressed, ensuring the stability of the reinforcing plate.

[0131] The reinforcing plate extends horizontally along its length so that its extension direction is perpendicular to the direction of gravity. This prevents the force on the reinforcing plate from concentrating on one side, i.e., one side of the connecting portion 42 is stressed while the other side experiences less stress, which would affect the stability of the reinforcing plate and even cause it to deform under stress. The reinforcing plate has a reinforcing portion 43, which strengthens the plate's structure, ensuring it has sufficient strength to support the clothing handling tube assembly 2 and preventing deformation, thus ensuring the stability of the reinforcing plate. The reinforcing portion 43 extends along the length of the reinforcing plate so that it can uniformly strengthen all parts along the length of the plate, avoiding stress concentration.

[0132] The reinforcing part 43 extends circumferentially along the mounting part 41 to reinforce the connection between the reinforcing plate and the clothing handling tube assembly 2, ensuring the strength of the connection between the clothing handling tube assembly 2 and the reinforcing plate, so that the reinforcing plate can better support the clothing handling tube assembly 2.

[0133] The reinforcing member 4 is located on the side of the air duct shell 13 facing away from the opening 1011 and is connected to the support plate 12. Thus, the reinforcing member 4 is located outside the ventilation cavity 101 and on the side of the air duct shell 13 facing away from the opening 1011. The clothes handling drum assembly 2 is rotatably connected to the reinforcing member 4 via a rotating shaft 23, which passes through the air duct shell 13 and connects to the reinforcing member 4 located outside the ventilation cavity 101. The reinforcing member 4 is partially bent to match the outer surface of the air duct shell 13. Thus, the reinforcing member 4 and the air duct shell 13 can be fitted together to simultaneously enhance the strength of both the reinforcing member 4 and the air duct shell 13, resulting in a higher overall structural strength and more stable installation of the dryer. At the same time, fitting the reinforcing member 4 to the air duct shell 13 also avoids the reinforcing member 4 occupying more space inside the dryer, ensuring the utilization rate of the internal space of the dryer and ensuring the miniaturization and lightweight of the dryer.

[0134] The reinforcing member 4 extends towards the direction of the clothes handling drum assembly 2, forming a mounting recess 44 on the side of the reinforcing member 4 facing away from the clothes handling drum assembly 2. The bearing seat 111 is at least partially disposed in the mounting recess 44. The opening of the mounting recess 44 can provide space for the installation of the bearing seat 111 and the bearing 112, and can also increase the mating area between the reinforcing member 4 and the bearing seat 111, making the installation of the bearing seat 111 more stable. Furthermore, it can also prevent the installation of the bearing seat 111 or the bearing 112 from increasing the axial dimensions of the air duct housing assembly 1 and the reinforcing member 4 in the clothes handling drum assembly 2, thereby preventing the installation of the bearing seat 111 from affecting the overall axial dimensions of the dryer in the clothes handling drum assembly 2, and realizing the miniaturization and weight reduction of the dryer.

[0135] The bearing housing 111 is disposed within the mounting recess 44. The inner wall of the mounting recess 44 can limit the bearing housing 111, ensuring the stability of the bearing housing 111. The shape of the bearing housing 111 is adapted to the shape of the mounting recess 44 so that the bearing housing 111 can be completely embedded in the mounting recess 44. The inner wall of the mounting recess 44 limits the bearing housing 111, ensuring the stability of the bearing housing 111. In addition, it can also prevent the mounting recess 44 from occupying too much space and affecting the ventilation space inside the ventilation cavity 101, reducing the impact of the mounting recess 44 on the air resistance inside the ventilation cavity 101.

[0136] The mounting recess 44 is located on the side of the reinforcing member 4 facing away from the clothing handling tube assembly 2. This allows the bearing housing 111 to be located outside the ventilation cavity 101 as much as possible, so that the bearing 112 and the bearing housing 111 do not need to directly contact the airflow in the ventilation cavity 101. This avoids water vapor in the airflow from corroding the bearing 112 or the bearing housing 111 and affecting the service life of the bearing 112 and the bearing housing 111.

[0137] Furthermore, the bottom wall of the mounting recess 44 is provided with an opening 441 to allow the rotating shaft 23 or bearing seat 111 to pass through, so as to connect the bearing seat 111 located on the rear side of the reinforcing member 4 and the clothing handling tube assembly 2 located on the front side of the reinforcing member 4.

[0138] Among them, the reinforcing member 4 has a mounting protrusion 45 on the side facing the clothing handling drum assembly 2, which corresponds to the position of the mounting recess 44. Since the reinforcing member 4 is fitted on the air duct shell 13, the structure of the part of the air duct shell 13 corresponding to the mounting protrusion 45 should be arranged to avoid the mounting protrusion 45. Therefore, the air duct shell 13 is provided with a clearance hole 134 to avoid structural redundancy at the position of the air duct shell 13 corresponding to the mounting protrusion 45, which would affect the axial size of the clothing handling drum assembly 2 of the air duct shell assembly 1. The mounting protrusion 45 is inserted into the clearance hole 134, and the mounting protrusion 45 can seal the clearance hole 134. In addition, the clearance hole 134 can also allow the rotating shaft 23 or the bearing seat 111 to pass through. The bearing 112 provided in the mounting recess 44 can pass through the bottom wall opening 441 of the mounting recess 44 and directly connect to the clothing handling drum assembly.
