[0044] Reference below Figure 1-Figure 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 utility model may include: A clothes dryer according to an embodiment of the present utility model includes: an air duct shell assembly 1 and a clothes processing drum assembly 2 .

[0046] The air duct shell assembly 1 of a traditional clothes dryer defines a ventilation cavity 101, and the clothing processing drum assembly 2 is arranged on one side of the air duct shell assembly 1 and is rotatably connected to the side wall on the same side of the air duct shell assembly 1. The inner cavity capacity of the clothing processing drum is limited by the size of the space in front of the air duct shell assembly 1 inside the dryer, and a hole 441 is required to be opened at a position corresponding to the clothing processing drum assembly 2 on the side wall of the air duct shell assembly 1 to connect the inner cavity of the clothing processing drum assembly 2 and the ventilation cavity 101. In the process of airflow flowing into the inner cavity of the clothing processing drum assembly 2, it is blocked by multiple structures, resulting in large airflow resistance, which affects the airflow flow rate and flow rate.

[0047] To this end, the embodiment of the utility model designs a dryer in which an air duct shell assembly 1 defines a ventilation chamber 101 with a through opening 1011 on one side, and a clothing processing drum assembly 2 has an air inlet 202, and the air inlet 202 connects the ventilation chamber 101 and the clothing processing chamber 201. As a result, the airflow only needs to pass through the air inlet 202 to enter the clothing processing chamber 201 from the ventilation chamber 101, thereby greatly reducing the wind resistance of the airflow flowing into the clothing processing chamber 201, and the clothing processing drum assembly 2 has no connection relationship with the front side structure of the air duct shell assembly 1, and part of the structure of the clothing processing drum assembly 2 can extend into the ventilation chamber 101 through the through opening 1011, and the capacity of the clothing processing chamber 201 is no longer limited by the space limitation in front of the air duct shell assembly 1, thereby increasing the capacity of the clothing processing chamber 201.

[0048] Since the support of the clothing processing drum assembly 2 needs to rely on a high-strength supporting structure, the air duct shell assembly 1 is provided with a reinforcement 4, and the clothing processing drum assembly 2 can be rotatably connected to the reinforcement 4 to support the clothing processing drum assembly 2 by relying on the high-strength reinforcement 4 to ensure the stability of the setting of the clothing processing drum assembly 2.

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

[0050] According to the clothes dryer of the embodiment of the utility model, the clothes processing chamber 201 of the clothes dryer has a large capacity and the clothes processing drum assembly 2 can be stably supported and arranged on the air duct shell assembly 1, and the production cost is low.

[0051] Combination Figure 1-Figure 9 In the illustrated embodiment, the air duct shell assembly 1 includes: a support plate 12 and an air duct shell 13, the through opening 1011 is arranged on the support plate 12, and the air duct shell 13 is arranged on one side of the support plate 12 in the thickness direction and covers the through opening 1011, so that the air duct shell 13 can jointly define a ventilation cavity 101 connected to the through opening 1011 with the support plate 12.

[0052] Among them, the reinforcement 4 can be connected to the air duct shell 13 so that the air duct shell 13 and the reinforcement frame are connected as a whole. While the strength of the air duct shell 13 is strengthened by the reinforcement 4, the air duct shell 13 can also stably support the reinforcement 4, so that the strength of the reinforcement frame is higher and better supports the clothing processing drum assembly 2.

[0053] The reinforcement frame can also be connected to the support plate 12 to rely on the high-strength support plate 12 structure to improve the strength of the reinforcement member 4, so that the reinforcement member 4 can more stably support the clothing processing drum assembly 2 and ensure the support stability of the clothing processing drum assembly 2.

[0054] The reinforcement 4 can also be connected to the air duct shell 13 and the support plate 12 at the same time, so that the support plate 12, the air duct shell 13 and the reinforcement 4 are stably connected as a whole, the overall structure is stable, the overall strength of the air duct shell assembly 1 is higher, which is conducive to supporting the clothing processing drum assembly 2.

[0055] Reference Figure 1-Figure 3 The reinforcement member 4 has a mounting portion 41 and a plurality of connecting portions 42. The mounting portion 41 is used to cooperate with the rotating shaft 23 for connection, and the connecting portion 42 is used to fix the reinforcement member 4 as a whole on the air duct shell assembly 1, and to strengthen the structure of the mounting portion 41, so as to ensure the strength of the mounting portion 41, ensure that the mounting portion 41 can stably support the clothing processing drum assembly 2, and ensure the stability of the clothing processing drum assembly 2 that cooperates with the mounting portion 41.

[0056] Specifically, the mounting portion 41 is disposed opposite to the through opening 1011 and the rotating shaft 23 is rotatably supported on the mounting portion 41 . The plurality of connecting portions 42 are located at the periphery of the through opening 1011 and connected to the air duct shell 13 and / or the support plate 12 .

[0057] When the connecting portion 42 is connected to the air duct shell 13, due to the low structural strength at the relative position of the air duct shell 13 and the opening 1011, the mounting portion 41 and the clothing processing drum assembly 2 cannot be stably supported. Therefore, the connecting portion 42 is arranged on the outer periphery of the opening 1011, so that the connecting portion 42 can be connected to the air duct shell 13 corresponding to the outer periphery of the opening 1011, and the connection between the connecting portion 42 and the air duct shell 13 is closer to the connection between the air duct shell 13 and the support plate 12, so that the reinforcement 4 and the clothing processing drum assembly 2 can be stably fixed to the support plate 12 indirectly through the air duct shell 13, thereby reducing the stress on the air duct shell 13, and relying on the high-strength support plate 12, the strength of the reinforcement plate is strengthened, so that the reinforcement 4 can stably support the clothing processing drum assembly 2, thereby ensuring the stability of the setting of the clothing processing drum assembly 2.

[0058] Alternatively, the connection portion 42 can be directly connected to the support plate 12 on the periphery of the opening 1011, so as to rely on the high-strength support plate 12 to strengthen the strength of the reinforcing plate, so that the reinforcing member 4 can stably support the clothing processing drum assembly 2 and ensure the stability of the clothing processing drum assembly 2.

[0059] Multiple connecting parts 42 are located on the periphery of the opening 1011, that is, the connecting parts 42 are close to or fitted to the air duct shell 13, which can also achieve space avoidance, thereby preventing the connecting parts 42 from occupying the ventilation space in the ventilation cavity 101 or the installation space on the rear side of the air duct shell 13, and preventing the setting of the reinforcement 4 from affecting the wind resistance in the ventilation cavity 101 or the installation of other structures inside the dryer, thereby achieving miniaturization and lightweight of the dryer.

[0060] like Figure 1-Figure 5As shown, the reinforcement member 4 forms a reinforcement plate to reduce the space occupied by the reinforcement member 4 in the thickness direction of the support plate 12 in the clothes dryer, thereby reducing the axial size of the clothes dryer laundry treatment drum assembly 2, which is conducive to the miniaturization and lightness of the clothes dryer. The mounting portion 41 is located in the middle of the length direction of the reinforcement plate, and the two ends of the reinforcement plate in the length direction have connecting portions 42, that is, the two sides of the reinforcement plate in the length direction are connected to the support plate 12 or the air duct shell 13. By arranging the mounting portion 41 that bears the weight of the clothes treatment drum assembly 2 in the middle of the length direction of the reinforcement plate, the connecting portions 42 at the two ends of the length direction of the reinforcement plate can be evenly stressed, ensuring the stability of the reinforcement plate setting.

[0061] Reference Figure 3 The length direction of the reinforcing plate extends in the horizontal direction 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 connecting portion 42 on one side is subjected to force, and the connecting portion 42 on the other side is subjected to less force, which affects the stability of the reinforcing plate and even causes the reinforcing plate to deform under force.

[0062] like Figure 1-Figure 3 As shown, the reinforcing plate has at least one reinforcing portion 43, which can reinforce the structure of the reinforcing plate itself, ensure that the reinforcing plate has sufficient strength to support the laundry treatment drum assembly 2, and can prevent the reinforcing plate from being deformed by force, thereby ensuring the stability of the reinforcing plate. The reinforcing portion 43 extends along the length direction of the reinforcing plate, so that the reinforcing portion 43 can evenly reinforce each part of the reinforcing plate in the length direction to avoid stress concentration.

[0063] Among them, the reinforcement part 43 includes at least one of a reinforcement recess and a reinforcement protrusion. By reinforcing the recess or the reinforcement protrusion, the overall strength of the reinforcement plate can be improved, and the production cost of the reinforcement plate is less affected. The reinforcement plate as a whole can be stamped and formed in one piece.

[0064] Among them, Figure 1 and Figure 2 As shown, at least a portion of the reinforcing portion 43 extends along the circumference of the mounting portion 41 to reinforce the connection between the reinforcing plate and the clothing processing drum assembly 2, thereby ensuring the strength of the connection between the clothing processing drum assembly 2 and the reinforcing plate, so that the reinforcing plate can better support the clothing processing drum assembly 2.

[0065] Combination Figure 1-Figure 3In the illustrated embodiment, a plurality of connecting holes 133 are provided on the air duct shell 13, and a plurality of matching holes 122 are provided on the support plate 12. The positions of the plurality of connecting holes 133 and the plurality of matching holes 122 correspond one to one. The support plate 12 and the air duct shell 13 are connected by a plurality of fasteners 14, and each fastener 14 is passed through the corresponding connecting hole 133 and the matching hole 122. Thus, the support plate 12 and the air duct shell 13 can be stably matched and connected together by the fasteners 14 passing through the connecting hole 133 and the matching hole 122, and the sealing of the ventilation cavity 101 is ensured.

[0066] Among them, the reinforcement 4 is located between two adjacent fasteners 14 to avoid the fastener 14 used to connect the support plate 12 and the air duct shell 13. On the one hand, it avoids the setting of the reinforcement 4 from affecting the installation of the fastener 14, ensuring that the fastener 14 has sufficient installation space. On the other hand, it avoids the reinforcement 4 from vibrating along with the operation of the clothing processing drum assembly 2, affecting the connection stability of the fastener 14, ensuring that the fastener 14 is stably set and the air duct shell 13 and the support plate 12 can be stably sealed.

[0067] There are at least three structures for installing the reinforcement 4, namely, the reinforcement 4 is located on the side of the air duct shell 13 facing away from the opening 1011 and is connected to at least the support plate 12, thus, the reinforcement 4 is arranged outside the ventilation cavity 101 and on the side of the air duct shell 13 facing away from the opening 1011, and the clothing processing drum assembly 2 is rotatably connected to the reinforcement 4 through the rotating shaft 23, and the rotating shaft 23 needs to pass through the air duct shell 13 and be connected to the reinforcement 4 arranged outside the ventilation cavity 101.

[0068] Alternatively, the reinforcement member 4 is connected to the side of the air duct housing 13 facing the through opening 1011 and is located between the air duct housing 13 and the support plate 12, and the clothes processing drum assembly 2 is rotatably connected to the reinforcement member 4 through the rotating shaft 23, that is, the reinforcement member 4 is arranged in the ventilation cavity 101, and the rotating shaft 23 can be directly connected to the reinforcement member 4 arranged in the ventilation cavity 101. The reinforcement member 4 is connected to the air duct housing 13.

[0069] Alternatively, the reinforcement member 4 is connected to the side of the support plate 12 facing the air duct housing 13, the air duct housing 13 covers the reinforcement member 4 so that the reinforcement member 4 is located between the air duct housing 13 and the support plate 12, and the clothes treatment drum assembly 2 is rotatably connected to the reinforcement member 4 through the rotating shaft 23, that is, the reinforcement member 4 is arranged in the ventilation cavity 101, and the rotating shaft 23 can be directly connected to the reinforcement member 4 arranged in the ventilation cavity 101. The reinforcement member 4 is connected to the support plate 12 to strengthen the strength of the reinforcement member 4 by using the high-strength support plate 12, thereby ensuring the support stability of the reinforcement member 4 on the clothes treatment drum assembly 2.

[0070] Reference Figure 1-Figure 3The reinforcement member 4 is at least partially bent to match the inner surface or the outer surface of the air duct shell 13, so that the reinforcement member 4 and the air duct shell 13 can be fitted together to strengthen the strength of the reinforcement member 4 and the air duct shell 13 at the same time, so that the overall structural strength of the dryer is higher and the setting is more stable. At the same time, fitting the reinforcement member 4 with the air duct shell 13 can also avoid the setting of the reinforcement member 4 occupying a larger space in the dryer, ensuring the utilization 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 clothes dryer further includes: a bearing seat 111, a bearing 112 is mounted on the bearing seat 111, and the rotating shaft 23 cooperates with the bearing 112 to be rotatably supported and arranged on the reinforcement member 4. The bearing seat 111 is used to install the bearing 112, and the bearing 112 includes an outer bearing and an inner bearing, the outer bearing is fixed on the bearing seat 111, and the inner bearing is fixedly connected to the rotating shaft 23, and the clothes processing drum assembly 2 is rotatably supported and arranged on the reinforcement member 4 through the bearing 112.

[0072] By molding the bearing seat 111 and the reinforcement 4 separately, and then assembling the bearing seat 111 on the reinforcement 4 by welding or fasteners 14, the production difficulty of the reinforcement 4 and the bearing seat 111 can be reduced, and the production cost of the dryer can be reduced.

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

[0074] The bearing seat 111 is arranged opposite to the through opening 1011 so that the bearing seat 111 and the bearing 112 arranged on the bearing seat 111 can be arranged at the position where the axis of the clothing processing drum assembly 2 intersects with the reinforcement 4. The clothing processing drum assembly 2 can rotate stably around its own axis, ensuring the stability of the clothing processing drum assembly 2.

[0075] Reference Figure 4 and Figure 5 , the reinforcement 4 partially extends in the direction close to the clothing processing drum assembly 2 to form a mounting recess 44 on the side of the reinforcement 4 facing away from the clothing processing drum assembly 2, and the bearing seat 111 is at least partially arranged in the mounting recess 44. The opening of the mounting recess 44 can provide space for the arrangement of the bearing seat 111 and the bearing 112, and can also increase the matching area between the reinforcement 4 and the bearing seat 111, so that the arrangement of the bearing seat 111 is more stable. Furthermore, it can also avoid the arrangement of the bearing seat 111 or the bearing 112 from increasing the axial size of the air duct shell assembly 1 and the reinforcement 4 in the clothing processing drum assembly 2, thereby avoiding the arrangement of the bearing seat 111 affecting the axial size of the dryer as a whole in the clothing processing drum assembly 2, thereby realizing the miniaturization and lightweight of the dryer.

[0076] The bearing seat 111 is arranged in the mounting recess 44, and the inner wall of the mounting recess 44 can limit the bearing seat 111 to ensure the stability of the bearing seat 111. The shape of the bearing seat 111 is adapted to the shape of the mounting recess 44 so that the bearing seat 111 can be completely embedded in the mounting recess 44. The inner wall of the mounting recess 44 is used to limit the bearing seat 111 to ensure the stability of the bearing seat 111. In addition, it can also avoid the mounting recess 44 occupying too much space to affect the space used for ventilation inside the ventilation cavity 101, thereby reducing the influence of the setting of the mounting recess 44 on the wind resistance in the ventilation cavity 101.

[0077] Among them, the mounting recess 44 is arranged on the side of the reinforcement 4 facing away from the clothing processing drum assembly 2, thereby, the bearing seat 111 is arranged outside the ventilation cavity 101 as much as possible, so that the bearing 112 and the bearing seat 111 do not need to directly contact the airflow in the ventilation cavity 101, thereby avoiding the water vapor in the airflow to corrode the bearing 112 or the bearing seat 111 and affect the service life of the bearing 112 and the bearing seat 111.

[0078] In addition, the bottom wall of the mounting recess 44 is provided with an opening 441 to allow the rotating shaft 23 or the bearing seat 111 to pass therethrough, so as to facilitate the connection between the bearing seat 111 disposed at the rear side of the reinforcement 4 and the laundry treatment drum assembly 2 disposed at the front side of the reinforcement 4 .

[0079] like Figure 4 and Figure 5 As shown, the bearing seat 111 includes a first seat body 1111 and a second seat body 1112, which are arranged relative to each other and define an installation space, and the installation space can provide space for the installation of the bearing 112, wherein the bearing 112 is a rolling bearing 112 and is arranged in the installation space, the rolling bearing 112 includes an outer bearing 112 and an inner bearing 112, the outer peripheral bearing 112 is fixedly arranged in the installation space, the inner bearing 112 is fixedly connected to the rotating shaft 23, the first seat body 1111 and the second seat body 1112 are stopped at opposite sides of the outer ring of the rolling bearing 112, that is, the first seat body 1111 and the second seat body 1112 respectively limit the bearing 112 on both sides of the axial direction of the bearing 112 to ensure the stability of the bearing 112. A limiting step 231 is provided on the rotating shaft 23, and the limiting step 231 stops on one side of the inner ring of the rolling bearing 112 to prevent the rotating shaft 23 from moving in the axial direction relative to the rolling bearing 112, thereby 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 processing drum assembly 2 connected to the rotating shaft 23 can rotate relative to the air duct shell assembly 1.

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

[0081] Among them, a mounting protrusion 45 corresponding to the position of the mounting recess 44 is formed on the side of the reinforcement 4 facing the clothing processing drum assembly 2. Since the reinforcement 4 is fittedly arranged on the air duct shell 13, the structure of the part of the air duct shell 13 corresponding to the mounting protrusion 45 should avoid the setting of the mounting protrusion 45. Therefore, the air duct shell 13 is provided with an avoidance hole 134 to avoid structural redundancy at the position corresponding to the air duct shell 13 and the mounting protrusion 45, which affects the axial size of the air duct shell assembly 1 and the clothing processing drum assembly 2. The mounting protrusion 45 is inserted into the avoidance hole 134, and the mounting protrusion 45 can seal the avoidance hole 134. In addition, the avoidance hole 134 can also allow the rotating shaft 23 or the bearing seat 111 structure to pass through, and the bearing 112 arranged in the mounting recess 44 can pass through the bottom wall opening 441 of the mounting recess 44 and be directly connected to the clothing processing barrel assembly.

[0082] In other embodiments, the reinforcement 4 is disposed in the ventilation cavity 101, that is, the reinforcement 4 is located between the air duct shell 13 and the support plate 12. Optionally, the reinforcement 4 can be spaced apart from the air duct shell 13, and the reinforcement 4 can also be arranged in close contact with the air duct shell 13. When the reinforcement 4 is arranged in close contact with the air duct shell 13, the strength of the reinforcement 4 and the air duct shell 13 is improved, and the axial size of the air duct shell assembly 1 in the clothing processing drum assembly 2 is smaller.

[0083] Among them, the bearing seat 111 is at least partially arranged between the air duct shell 13 and the reinforcement 4, so that the air duct shell 13 and the reinforcement 4 can jointly protect the bearing seat 111 and the bearing 112 arranged on the bearing seat 111, ensure the stability of the bearing seat 111 and the bearing 112, and, in some embodiments, a closed installation space for the bearing seat 111 is defined between the reinforcement 4 and the air duct shell 13, and the bearing seat 111 is arranged in the installation space to prevent it from being corroded by the external environment and increase its service life.

[0084] In some embodiments, the air duct shell 13 is an integral injection-molded part to reduce the mass of the air duct shell 13 . The air duct shell assembly 1 is integrally formed as a whole, which simplifies the installation steps and ensures the sealing of the ventilation cavity 101 .

[0085] Alternatively, in other embodiments, the air duct shell 13 includes at least two separately formed structural parts, which cooperate with the support plate 12 to define the structure of the ventilation cavity 101. Splitting the air duct shell 13 into two separately formed structural parts is helpful to simplify the production and processing difficulty of the air duct shell 13, and the two parts of the structural parts can be made of different materials according to needs, saving production costs.

[0086] Furthermore, the reinforcement member 4 is a metal member, so as to utilize the high strength of the metal member to ensure the strength of the reinforcement member 4 and further ensure the stability of the clothing treatment drum assembly 2 supported on the reinforcement member 4 .

[0087] The capacity of the traditional clothes processing chamber 201 of the dryer is limited by the size of the space in front of the air duct shell assembly 1 inside the dryer, and the airflow is blocked by multiple structures during the process of flowing into the clothes processing chamber 201, resulting in large airflow resistance, which affects the airflow flow and flow rate.

[0088] In the embodiment of the utility model, a part of the clothing processing drum assembly 2 extends from the through opening 1011 into the ventilation cavity 101 and the air inlet portion 202 is arranged on the partial structure, and the air inlet portion 202 connects the ventilation cavity 101 and the clothing processing cavity 201, thereby, the airflow only needs to pass through the air inlet portion 202 to enter the clothing processing cavity 201 from the ventilation cavity 101, which greatly reduces the wind resistance of the airflow in the process of flowing into the clothing processing cavity 201, and the partial structure of the clothing processing drum assembly 2 can extend into the ventilation cavity 101 through the through opening 1011, and the capacity of the clothing processing cavity 201 is no longer limited by the space limitation in front of the air duct shell assembly 1, thereby increasing the capacity of the clothing processing cavity 201.

[0089] Reference Figure 1 and Fig. 9 The support plate 12 also has an air port 1012 located on one side of the through port 1011. The air port 1012 can deliver airflow into the ventilation cavity 101. The airflow enters the ventilation cavity 101 through the air port 1012, and then enters the clothing processing cavity 201 through the through port 1011 to participate in clothing processing. A wind wheel is arranged in the ventilation cavity 101 opposite to the air port 1012, which is used to drive the airflow to circulate in the ventilation cavity 101 and the clothing processing cavity 201.

[0090] According to some embodiments of the utility model, the clothes dryer further comprises a mounting seat, which defines an air duct to connect the clothing processing chamber 201 and the ventilation chamber 101, and a heating element is arranged in the air duct. During the operation of the clothes dryer, the wet and cold airflow in the clothing processing chamber 201 passes through the air duct defined by the mounting seat, is heated and dehumidified in the air duct, passes through the air port 1012, and enters the ventilation chamber 101 defined by the air duct shell assembly 1 under the drive of the wind wheel, and the dry and hot airflow in the ventilation chamber 101 then enters the clothing processing chamber 201 through the air inlet 202 of the clothing processing drum assembly 2, and the clothing is dried.

[0091] According to some embodiments of the utility model, the clothes dryer further includes: a heat pump system, the heat pump system includes an evaporator, a condenser and a compressor, and the heating element includes an evaporator and a condenser. In the clothing processing chamber 201, the dry hot air passes through the wet clothes, the moisture remaining on the clothes absorbs heat, and the air becomes hot and humid air. The hot and humid air enters the air duct, and the hot and humid air is converted into dry cold air after passing through the condenser, and the water vapor in the air condenses into water droplets and is 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 clothes dryer of the present utility model is described below with reference to the accompanying drawings.

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

[0094] The clothes treatment drum assembly 2 defines a clothes treatment chamber 201, which is used to accommodate clothes to be treated. The capacity of the clothes treatment chamber 201 affects the number of clothes that the dryer can treat at the same time and the size of clothes that the dryer can treat. In order to improve the user experience, the volume of the clothes treatment chamber 201 should be as large as possible. The air duct housing assembly 1 defines a ventilation chamber 101, and the dryer can deliver high-temperature airflow into the clothes treatment chamber 201 through the ventilation chamber 101 to achieve the clothes drying function.

[0095] Among them, one side of the air duct shell assembly 1 has a through opening 1011, and a part of the clothing processing drum assembly 2 extends from the through opening 1011 into the ventilation cavity 101, thereby, the clothing processing drum assembly 2 can extend backward until it extends into the ventilation cavity 101, and the clothing processing drum assembly 2 can be designed to be deeper without changing the external dimensions of the dryer, thereby increasing the capacity of the clothing processing cavity 201, and the dryer can process more and larger clothes at the same time, improving the user experience.

[0096] The clothes treatment drum assembly 2 has an air inlet 202, which can directly connect the ventilation cavity 101 and the clothes treatment cavity 201. That is to say, during the flow of air, the air in the ventilation cavity 101 can directly enter the clothes treatment cavity 201 through the air inlet 202. On this basis, the original complex structure of the air outlet area on the air duct shell assembly 1 can directly open a larger opening 1011, which reduces the production cost of the dryer.

[0097] The clothing processing drum assembly 2 is provided with a rotating shaft 23, that is, one end of the rotating shaft 23 is fixedly connected to the clothing processing drum assembly 2, and the clothing processing drum assembly 2 is rotatably supported on the air duct shell assembly 1 through the rotating shaft 23, so 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. The through 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 through opening 1011. The air duct shell 13 and the support plate 12 together define a ventilation cavity 101.

[0099] The clothes treatment drum assembly 2 comprises: a drum body 211 and an air inlet cover 22. The drum body 211 has a clothes taking-in and putting-out opening at one axial end and an open opening at the other axial end, wherein the clothes taking-in and putting-out opening faces the front side of the clothes dryer, and the user can put clothes into the clothes treatment chamber 201 through the clothes taking-in and putting-out opening, and the open opening faces the rear side of the clothes dryer, and the airflow can enter the cavity defined by the drum body 211 through the open opening to dry the clothes, and the cavity defined by the drum body 211 is the part of the clothes treatment chamber 201 mainly used for accommodating clothes. The air inlet cover 22 covers the open opening to define the clothes treatment chamber 201 together with the drum body 211, and the air inlet cover 22 can separate the ventilation chamber 101 from the clothes treatment chamber 201 on the one hand, and prevent the clothes from entering the ventilation chamber 101 through the open opening, and on the other hand, the air inlet cover 22 provides an installation position for the setting of the rotating shaft 23, and the rotating shaft 23 is arranged on the air inlet cover 22, so as to ensure that the rotating shaft 23 can stably support the clothes treatment drum assembly 2 as a whole.

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

[0101] At least a portion of the air inlet cover 22 extends from the opening 1011 into the ventilation cavity 101, so that the clothing processing cavity 201 can extend into the ventilation cavity 101, and part of the space in the ventilation cavity 101 is used to increase the depth of the clothing processing cavity 201 and increase the capacity of the clothing processing cavity 201. The air inlet portion 202 is arranged around the rotating shaft 23 to ensure the strength of the connection between the rotating shaft 23 and the air inlet cover 22, to avoid the setting of the air inlet portion 202 affecting the connection between the rotating shaft 23 and the air inlet cover 22, and to avoid the setting of the rotating shaft 23 affecting the air inlet area of ​​the air inlet portion 202, to ensure the air intake volume of the air inlet portion 202.

[0102] The middle part of the air inlet cover 22 extends in the direction close to the clothing loading and unloading port to form a accommodating recess 221 on the outer surface of the air inlet cover 22. The rotating shaft 23 is arranged on the bottom wall of the accommodating recess 221 and protrudes from the plane where the opening of the accommodating recess 221 is located. The opening of the accommodating recess 221 can provide an installation space for the setting of the rotating shaft 23 and the connecting structure between the rotating shaft 23 and the air inlet cover 22, thereby avoiding interference with the structure on the rear side and affecting the normal operation and rotation of the clothing processing drum assembly 2. It can also avoid that the setting of the rotating shaft 23 and the connecting structure between the rotating shaft 23 and the air inlet cover 22 increases the axial size of the clothing processing drum assembly 2 and affects the overall volume of the dryer.

[0103] The rotating shaft 23 protrudes from the plane where the opening of the accommodating recess 221 is located, so as to be rotatably connected to the structure of the air duct shell assembly 1 located behind the clothing processing drum assembly 2, so that the clothing processing drum assembly 2 as a whole can be supported and set on the air duct shell assembly 1.

[0104] The accommodating recess 221 is arranged 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 chamber 201, and prevent the setting of the rotating shaft 23 and other structures from increasing the edges and corners in the clothing processing chamber 201 and causing damage to the clothes.

[0105] In some embodiments, the connection structure between the air duct shell assembly 1 and the rotating shaft 23 is arranged on the rear side of the accommodating recess 221. By setting the accommodating recess 221, installation space can also be reserved for the setting of the connection structure between the air duct shell assembly 1 and the rotating shaft 23, so that the internal space distribution of the dryer is more reasonable.

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

[0107] The second extension portion 224 is a non-porous structure and defines a second chamber 2012. The second extension portion 224 can separate the clothing treatment drum assembly 2 from the air duct shell assembly 1 to avoid interference between the clothing treatment drum assembly 2 and the air duct shell assembly 1 during rotation.

[0108] Among them, the second extension portion 224 is located between the first extension portion 223 and the barrel 211 and the first extension portion 223 extends in a direction away from the barrel 211 relative to the second extension portion 224. The clothing processing chamber 201 includes a first chamber 2011, a second chamber 2012 and an inner cavity defined by the barrel 211. In the axial direction of the barrel 211, the second chamber 2012 is connected between the first chamber 2011 and the inner cavity of the barrel 211. Thus, the airflow flows through the inner cavities of the first cavity, the second cavity and the barrel 211 in turn, ensuring uniform air volume in the clothing processing chamber 201.

[0109] The first extension portion 223 includes an end wall arranged opposite to the clothing access opening and a peripheral wall surrounding the end wall, and the air inlet portion 202 is arranged on the end wall of the first extension portion 223 and / or the peripheral wall of the first extension portion 223, wherein the rotating shaft 23 is arranged on the end wall of the first extension portion 223.

[0110] The end wall of the first extension portion 223 is also provided with a structural reinforcement portion 43, at least a portion of which extends along the circumference of the rotating shaft 23 to reinforce the end wall structure of the clothing processing drum assembly 2 for connection with the rotating shaft 23, thereby ensuring the stability of the clothing processing drum assembly 2.

[0111] The first extension part 223 is provided with an air inlet 202 in communication with the clothing processing chamber 201, and the air flow can enter the clothing processing chamber 201 through the air inlet 202 provided on the first extension part 223. The air inlet 202 includes a plurality of air inlet holes, and the plurality of air inlet holes are arranged at intervals on the peripheral wall and the end wall of the first extension part 223, so that the air inlet holes are evenly distributed on the first extension part 223, which ensures, on the one hand, that the weight of the clothing processing drum assembly 2 in all directions is even, and ensures that the clothing processing drum assembly 2 can rotate stably, and on the other hand, during the rotation of the clothing processing drum assembly 2, the air flow can stably enter the clothing processing chamber 201 through the evenly arranged air inlet holes, ensuring the stability of the air flow in the clothing processing chamber 201.

[0112] The end wall of the first extension part 223 is connected to the peripheral wall of the first extension part 223 by an arc transition. When the airflow passes through the connection between the end wall of the first extension part 223 and the peripheral wall of the first extension part 223, the airflow can be smoothly guided by the arc transition section, thereby avoiding the large resistance of the airflow when passing through the turning point, impacting the structure of the first extension part 223 and causing noise, avoiding the loss of airflow, and reducing the difficulty of punching in the production process.

[0113] like Fig. 9 As shown, the shape of the through opening 1011 is circular to correspond to the shape of the first extension portion 223 extending into the ventilation cavity 101, so that the first extension portion 223 can be set as large as possible.

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

[0115] Since the clothes treatment drum assembly 2 is easy to collide with the hole edge of the opening 1011 during the installation process, and the hole edge of the opening 1011 is relatively low in strength and has a sharp edge, which will affect the safety of the installation process, a protective structure 121 is provided at the edge of the opening 1011, such as Figure 7As 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 installation, and on the other hand, can 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 the edge of the opening 1011 is affected by external force.

[0116] The protection structure 121 may be a flange structure or a curling structure.

[0117] In some embodiments, the air duct shell assembly 1 further has an air outlet 1012 located on one side of the through port 1011, and a wind wheel arranged opposite to the air outlet 1012 is arranged in the ventilation cavity 101. The clothes dryer further comprises a mounting seat, which defines an air duct to connect the clothing processing cavity 201 and the ventilation cavity 101, and a heating element is arranged in the air duct. During the operation of the clothes dryer, the wet and cold airflow in the clothing processing cavity 201 passes through the air duct defined by the mounting seat, is heated and dehumidified in the air duct, passes through the air outlet 1012, and enters the ventilation cavity 101 defined by the air duct shell assembly 1 under the drive of the wind wheel, and the dry and hot airflow in the ventilation cavity 101 then enters the clothing processing cavity 201 through the air inlet 202 of the clothing processing drum assembly 2, and the clothes are dried.

[0118] According to some embodiments of the utility model, the clothes dryer further includes: a heat pump system, the heat pump system includes an evaporator, a condenser and a compressor, and the heating element includes an evaporator and a condenser. In the clothing processing chamber 201, the dry hot air passes through the wet clothes, the moisture remaining on the clothes absorbs heat, and the air becomes hot and humid air. The hot and humid air enters the air duct, and the hot and humid air is converted into dry cold air after passing through the condenser, and the water vapor in the air condenses into water droplets and is 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 cover 22 is an integrated part. During the operation of the dryer, in order to ensure that the clothing processing drum assembly 2 can rotate stably, a gap is provided between the air duct shell assembly 1 and the clothing processing drum assembly 2. The air flow will flow out through the gap, causing air volume loss. Therefore, a sealing ring 3 is provided between the air inlet cover 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 part 202, so as to achieve sealing between the air duct shell assembly 1 and the clothing processing drum assembly 2.

[0120] Furthermore, since the air inlet cover 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 cover 22 relative to the air duct shell assembly 1, the sealing ring 3 is fixed on one of the air inlet cover 22 and the air duct shell assembly 1, and the other one is movably cooperated with the sealing ring 3.

[0121] Reference Figure 7-Figure 9The protection structure 121 includes a limiting flange. Specifically, the edge of the through opening 1011 has a limiting flange extending in the direction close to the cylinder 211. The sealing ring 3 is sleeved on the outside of the limiting flange. That is to say, the limiting flange can limit the sealing ring 3, provide an installation position for the setting of the sealing ring 3, and avoid the sealing ring 3 from moving and affecting the sealing performance.

[0122] Furthermore, the limiting flange is also a protective structure 121 disposed at the edge of the through opening 1011, and the setting of the limiting flange is more practical.

[0123] The air duct shell assembly 1 is provided with a bearing seat 111 arranged opposite to the through opening 1011, and a bearing 112 is installed on the bearing seat 111. The rotating shaft 23 cooperates with the bearing 112 so that the clothing processing barrel assembly can be rotatably supported on the air duct shell assembly 1. Therefore, the rotating shaft 23 can be rotatably connected to the bearing seat 111 through the bearing 112, and then the rotating shaft 23 can be rotatably connected to the air duct shell assembly 1, and the clothing processing barrel assembly 2 can be rotatably supported and arranged on the air duct shell assembly 1.

[0124] The clothing processing drum assembly 2 has a receiving recess 221 which opens toward the bearing seat 111, and the rotating shaft 23 is arranged on the bottom wall of the receiving recess 221. The opening of the receiving recess 221 can provide an installation space for the setting of the rotating shaft 23 and the connecting structure between the rotating shaft 23 and the air inlet cover 22, thereby avoiding interference with the rear side air duct shell assembly 1, the bearing seat 111 and the mounting structure of the bearing seat 111, thereby affecting the normal operation and rotation of the clothing processing drum assembly 2, and avoiding the setting of the rotating shaft 23 and the connecting structure between the rotating shaft 23 and the air inlet cover 22 from increasing the axial size of the clothing processing drum assembly 2 and affecting the overall volume of the dryer.

[0125] The connecting portion 42 between the air duct shell assembly 1 and the rotating shaft 23 and the bearing seat 111 are arranged on the rear side of the accommodating recess 221. By setting the accommodating recess 221, installation space can also be reserved for the connecting portion 42 between the air duct shell assembly 1 and the rotating shaft 23 and the bearing seat 111, so that the internal space distribution of the dryer is more reasonable.

[0126] The bearing seat 111 at least partially extends from the opening of the accommodating recess 221 into the accommodating recess 221 to enable the bearing 112 to cooperate with the rotating shaft 23, and can shorten the distance between the bearing seat 111 and the connection position between the clothing processing drum assembly 2 and the rotating shaft 23, thereby reducing the stress on the rotating shaft 23.

[0127] The bearing seat 111 includes a first seat body 1111 and a second seat body 1112, which are arranged relative to each other and define an installation space, and the installation space can provide space for the installation of the bearing 112, wherein the bearing 112 is a rolling bearing 112 and is arranged in the installation space, the rolling bearing 112 includes an outer bearing 112 and an inner bearing 112, the outer peripheral bearing 112 is fixedly arranged in the installation space, the inner bearing 112 is fixedly connected to the rotating shaft 23, the first seat body 1111 and the second seat body 1112 are stopped at opposite sides of the outer ring of the rolling bearing 112, that is, the first seat body 1111 and the second seat body 1112 respectively limit the bearing 112 on both sides of the axial direction of the bearing 112 to ensure the stability of the bearing 112. A limiting step 231 is provided on the rotating shaft 23, and the limiting step 231 stops on one side of the inner ring of the rolling bearing 112 to prevent the rotating shaft 23 from moving in the axial direction relative to the rolling bearing 112, thereby 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 processing drum assembly 2 connected to the rotating shaft 23 can rotate relative to the air duct shell assembly 1.

[0128] In some embodiments, in combination Figure 1-Figure 6 In the illustrated embodiment, the air duct shell assembly 1 also includes: a reinforcement member 4, and the clothing processing drum assembly 2 is rotatably connected to the reinforcement member 4, so as to rely on the high-strength reinforcement member 4 to achieve stable support for the clothing processing drum assembly 2, and the reinforcement member 4 has a mounting portion 41 and a connecting portion 42. The reinforcement member 4 is used to support the clothing processing drum assembly 2 to ensure the stability of the setting of the clothing processing drum assembly 2.

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

[0130] The reinforcement member 4 forms a reinforcement plate to reduce the space occupied by the reinforcement member 4 in the thickness direction of the support plate 12 in the dryer. The installation portion 41 is located in the middle of the length direction of the reinforcement plate, and the two ends of the length direction of the reinforcement plate have connecting portions 42, that is, the two sides of the length direction of the reinforcement plate are connected to the support plate 12 or the air duct shell 13. By arranging the installation portion 41 that bears the weight of the clothing processing drum assembly 2 in the middle of the length direction of the reinforcement plate, the connecting portions 42 at the two ends of the length direction of the reinforcement plate can be evenly stressed, thereby ensuring the stability of the reinforcement plate setting.

[0131] The length direction of the reinforcing plate extends in the horizontal direction so that the extension direction of the reinforcing plate is perpendicular to the gravity direction, so as to avoid the force on the reinforcing plate being concentrated on one side of the reinforcing plate, that is, the connection part 42 on one side is subjected to force, and the connection part 42 on the other side is subjected to less force, which affects the stability of the reinforcing plate and even causes the reinforcing plate to deform under force. The reinforcing plate has a reinforcing part 43, which can reinforce the structure of the reinforcing plate itself, ensure that the reinforcing plate has sufficient strength to support the clothing treatment drum assembly 2, and can avoid the reinforcing plate from being deformed under force, and ensure the stability of the reinforcing plate. The reinforcing part 43 extends along the length direction of the reinforcing plate, so that the reinforcing part 43 can evenly reinforce each part of the reinforcing plate in the length direction to avoid stress concentration.

[0132] Part of the reinforcement portion 43 extends along the circumference of the mounting portion 41 to reinforce the connection between the reinforcement plate and the laundry processing drum assembly 2, ensuring the strength of the connection between the laundry processing drum assembly 2 and the reinforcement plate, so that the reinforcement plate can better support the laundry processing drum assembly 2.

[0133] The reinforcement member 4 is located on the side of the air duct shell 13 facing away from the through-port 1011 and is connected to the support plate 12. Thus, the reinforcement member 4 is arranged outside the ventilation cavity 101 and on the side of the air duct shell 13 facing away from the through-port 1011. The clothes processing drum assembly 2 is rotatably connected to the reinforcement member 4 through the rotating shaft 23. The rotating shaft 23 needs to pass through the air duct shell 13 and connect with the reinforcement member 4 arranged outside the ventilation cavity 101. The reinforcement member 4 is partially bent to match the outer surface of the air duct shell 13. Thus, the reinforcement member 4 and the air duct shell 13 can be fitted together to strengthen the strength of the reinforcement member 4 and the air duct shell 13 at the same time, so that the overall structural strength of the dryer is higher and the arrangement is more stable. At the same time, the fitting arrangement of the reinforcement member 4 and the air duct shell 13 can also avoid the arrangement of the reinforcement member 4 occupying a larger space in the dryer, ensuring the utilization rate of the internal space of the dryer, and ensuring the miniaturization and lightness of the dryer.

[0134] The reinforcement 4 partially extends in the direction close to the clothing processing drum assembly 2 to form a mounting recess 44 on the side of the reinforcement 4 facing away from the clothing processing 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 arrangement of the bearing seat 111 and the bearing 112, and can also increase the matching area between the reinforcement 4 and the bearing seat 111, so that the arrangement of the bearing seat 111 is more stable. Furthermore, it can also avoid the arrangement of the bearing seat 111 or the bearing 112 from increasing the axial size of the air duct shell assembly 1 and the reinforcement 4 in the clothing processing drum assembly 2, thereby avoiding the arrangement of the bearing seat 111 affecting the axial size of the dryer as a whole in the clothing processing drum assembly 2, thereby realizing the miniaturization and lightweight of the dryer.

[0135] The bearing seat 111 is arranged in the mounting recess 44, and the inner wall of the mounting recess 44 can limit the bearing seat 111 to ensure the stability of the bearing seat 111. The shape of the bearing seat 111 is adapted to the shape of the mounting recess 44 so that the bearing seat 111 can be completely embedded in the mounting recess 44. The inner wall of the mounting recess 44 is used to limit the bearing seat 111 to ensure the stability of the bearing seat 111. In addition, it can also avoid the mounting recess 44 occupying too much space to affect the space used for ventilation inside the ventilation cavity 101, thereby reducing the influence of the setting of the mounting recess 44 on the wind resistance in the ventilation cavity 101.

[0136] Among them, the mounting recess 44 is arranged on the side of the reinforcement 4 facing away from the clothing processing drum assembly 2, thereby, the bearing seat 111 is arranged outside the ventilation cavity 101 as much as possible, so that the bearing 112 and the bearing seat 111 do not need to directly contact the airflow in the ventilation cavity 101, thereby avoiding the water vapor in the airflow to corrode the bearing 112 or the bearing seat 111 and affect the service life of the bearing 112 and the bearing seat 111.

[0137] In addition, the bottom wall of the mounting recess 44 is provided with an opening 441 to allow the rotating shaft 23 or the bearing seat 111 to pass therethrough, so as to facilitate the connection between the bearing seat 111 disposed at the rear side of the reinforcement 4 and the laundry treatment drum assembly 2 disposed at the front side of the reinforcement 4 .

[0138] Among them, a mounting protrusion 45 corresponding to the position of the mounting recess 44 is formed on the side of the reinforcement 4 facing the clothing processing drum assembly 2. Since the reinforcement 4 is fittedly arranged on the air duct shell 13, the structure of the part of the air duct shell 13 corresponding to the mounting protrusion 45 should avoid the setting of the mounting protrusion 45. Therefore, the air duct shell 13 is provided with an avoidance hole 134 to avoid structural redundancy at the position corresponding to the air duct shell 13 and the mounting protrusion 45, which affects the axial size of the air duct shell assembly 1 and the clothing processing drum assembly 2. The mounting protrusion 45 is inserted into the avoidance hole 134, and the mounting protrusion 45 can seal the avoidance hole 134. In addition, the avoidance hole 134 can also allow the rotating shaft 23 or the bearing seat 111 structure to pass through, and the bearing 112 arranged in the mounting recess 44 can pass through the bottom wall opening 441 of the mounting recess 44 and be directly connected to the clothing processing barrel assembly.
