[0051] Reference below Figure 1-Figure 15 A clothes dryer according to an embodiment of the present invention is described.

[0052] The clothes dryer according to the embodiment of the utility model may include: an air duct housing assembly 1 and a clothes processing drum assembly 2 .

[0053] The clothing processing drum assembly 2 is rotatably supported on the air duct shell assembly 1 via the 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 via the rotating shaft 23, so the other end of the rotating shaft 23 is rotatably supported on the air duct shell assembly 1.

[0054] 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 through a rotating shaft 23. 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 the airflow flowing into the inner cavity of the clothing processing drum assembly 2, it is blocked by multiple structures, and the airflow resistance is large, which affects the airflow flow rate and flow rate.

[0055] To this end, the embodiment of the utility model designs a duct shell assembly 1 that defines a ventilation chamber 101 with a through opening 1011 on one side, and the clothing processing drum assembly 2 is provided with an air inlet portion 202, and the air inlet portion 202 connects the ventilation chamber 101 and the clothing processing chamber 201 of the dryer. Therefore, the airflow only needs to pass through the air inlet portion 202 to enter the clothing processing chamber 201 from the ventilation chamber 101, thereby greatly reducing the wind resistance during the process of the airflow flowing into the clothing processing chamber 201.

[0056] In addition, the clothing processing drum assembly 2 defines a clothing processing chamber 201, and a portion of the clothing processing drum assembly 2 extends from the opening 1011 into the ventilation chamber 101. 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.

[0057] According to the dryer of the embodiment of the utility model, the process of the airflow of the dryer flowing from the ventilation chamber 101 into the clothing processing chamber 201 is smoother, and the air volume loss is reduced. Under the same volume, the capacity of the clothing processing chamber 201 can be designed to be larger, which is more conducive to the miniaturization and lightweight of the dryer.

[0058] Reference Figure 1 , Figure 3 , Figure 5 , Fig.11 and Fig.13 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. The clothes taking-in and putting-out opening faces the front side of the clothes dryer. The user can put clothes into the clothes treatment chamber 201 through the clothes taking-in and putting-out opening. The open opening faces the rear side of the clothes dryer. The airflow can enter the cavity defined by the drum body 211 through the open opening to dry the clothes. The cavity defined by the drum body 211 is the part of the clothes treatment chamber 201 mainly used to accommodate clothes. The air inlet cover 22 covers the open opening to define the clothes treatment chamber 201 together with the drum body 211. On the one hand, the air inlet cover 22 can separate the ventilation chamber 101 from the clothes treatment chamber 201 to prevent the clothes from entering the ventilation chamber 101 through the open opening. On the other hand, the air inlet cover 22 provides an installation position for the connection of the rotating shaft 23. The rotating shaft 23 is connected to the air inlet cover 22 to ensure that the rotating shaft 23 can stably support the clothes treatment drum assembly 2 as a whole.

[0059] 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.

[0060] Among them, at least a part 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. Therefore, when the axial dimensions of the clothing processing drum assembly 2 of the dryer are the same, by opening the opening 1011 on one side of the air duct shell assembly 1 and extending the air inlet cover 22 of the clothing processing drum assembly 2 into the air duct cavity, the capacity of the clothing processing cavity 201 can be increased and the user experience can be improved.

[0061] Among them, the air inlet part 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 part 202 affecting the connection between the rotating shaft 23 and the air inlet cover 22, and at the same time to avoid the setting of the rotating shaft 23 affecting the air inlet area of ​​the air inlet part 202, to ensure the air intake volume of the air inlet part 202.

[0062] Combination Figure 3 , Figure 4 , Figure 6 , Fig.13 and Fig.14 In the illustrated embodiment, the middle portion of the air inlet cover 22 extends toward the direction close to the clothing loading and unloading port to form a receiving recess 221 on the outer surface of the air inlet cover 22, and the rotating shaft 23 is arranged 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 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, and can also avoid the setting of the rotating shaft 23 and the connecting structure between the rotating shaft 23 and the air inlet cover 22 increasing the axial size of the clothing processing drum assembly 2 and affecting the overall volume of the dryer.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] Reference Fig.13 and Fig.15 The air inlet cover 22 has 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 clothing processing cavity 201 includes the inner cavity of the barrel 211 and the first chamber 2011. After passing through the air inlet portion 202, the airflow first enters the first chamber 2011, and then flows from the first chamber 2011 to the inner cavity of the barrel 211. The air inlet portion 202 is arranged on the first extension portion 223 so that the air inlet portion 202 can directly connect the ventilation cavity 101 and the first chamber 2011. The rotating shaft 23 is arranged on the first extension portion 223 so that the rotating shaft 23 can be arranged at the center of the clothing processing barrel assembly 2.

[0067] like Fig.13 and Fig.15 As shown, the air inlet cover 22 also has a second extension portion 224 extending in a direction away from the barrel 211, the second extension portion 224 is a non-porous structure and defines a second chamber 2012, the second extension portion 224 does not correspond to the through opening 1011, and the setting of the second extension portion 224 can separate the clothing processing barrel assembly 2 from the air duct shell assembly 1 to avoid interference between the clothing processing barrel assembly 2 and the air duct shell assembly 1 during rotation.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] Combination Figure 1-Figure 6 as well as Figure 10-15 In the illustrated embodiment, 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. Thus, 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.

[0072] like Figure 6 and Fig.14 As shown, 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 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.

[0073] 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.

[0074] 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.

[0075] Reference Figure 6 and Fig.14 The air duct shell assembly 1 has a through hole 1312 arranged opposite to the through hole 1011 to allow the bearing seat 111 or the rotating shaft 23 to pass through, thereby, the rotating shaft 23 can connect the cover body 131 located in the ventilation cavity 101 and the bearing seat 111 arranged outside the ventilation cavity 101.

[0076] like Figure 6 , Fig.13 and Fig.14 As shown, the side of the air duct shell assembly 1 facing away from the clothing processing drum assembly 2 has a placement recess 1311. The opening of the placement recess 1311 can provide space for the arrangement of the bearing seat 111 and the bearing 112, thereby preventing the arrangement of the bearing seat 111 or the bearing 112 from increasing the axial size of the air duct shell assembly 1 in the clothing processing drum assembly 2 and affecting the overall volume and size of the dryer.

[0077] The placement recess 1311 is arranged on the side of the air duct shell assembly 1 facing away from the clothing processing drum assembly 2, that is, outside the ventilation cavity 101, to prevent the airflow in the ventilation cavity 101 from eroding the bearing 112 and the bearing seat 111, thereby ensuring the service life of the bearing 112 and the bearing seat 111.

[0078] The bearing seat 111 is arranged in the placement recess 1311, and the inner wall of the placement recess 1311 can limit the bearing seat 111 to ensure the stability of the connection between the bearing seat 111 and the air duct shell assembly 1. The through hole 1312 is arranged on the bottom wall of the placement recess 1311 so that the rotating shaft 23 can pass through the air duct shell assembly 1 and connect with the clothing treatment drum assembly 2. The shape of the bearing seat 111 is adapted to the shape of the placement recess 1311, so that the size of the placement recess 1311 is appropriate, so as to avoid the setting of the placement recess 1311 affecting the ventilation volume in the ventilation cavity 101, and the placement recess 1311 is used to limit the bearing seat 111 to avoid the bearing seat 111 from moving relative to the air duct shell assembly 1 and affecting the stability of the support setting of the clothing treatment drum assembly 2.

[0079] Combination Figure 6 and Fig.14 In the illustrated embodiment, 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 and is arranged in the installation space, the rolling bearing includes an outer bearing and an inner bearing, the outer bearing is fixedly arranged in the installation space, and the inner bearing is fixedly connected to the rotating shaft 23, and the first seat body 1111 and the second seat body 1112 are stopped at opposite sides of the outer ring of the rolling bearing, 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 to prevent the rotating shaft 23 from moving in the axial direction relative to the rolling bearing, affecting the stability of the connection of the rotating shaft 23. The inner bearing of the inner ring of the rolling bearing 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] like Figure 1-Figure 15 As shown, the air duct shell assembly 1 includes: a support plate 12 and an air duct shell 13.

[0081] Among them, the 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 opening 1011. Thus, the air duct shell 13 and the support plate 12 define a ventilation cavity 101 having the opening 1011, and can be connected with the clothing processing cavity 201 through the opening 1011.

[0082] The rotating shaft 23 can be rotatably supported on the air duct shell 13 so as to stably support the clothing processing drum assembly 2 in the dryer without adding an installation structure. By connecting the rotating shaft 23 extending backward with the air duct shell 13, the stability of the clothing processing drum assembly 2 can be ensured without affecting the production cost of the dryer.

[0083] Reference Figure 3 , Fig. 9 and Fig.10 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.

[0084] 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.

[0085] 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.

[0086] A specific embodiment of the clothes dryer of the present utility model is described below with reference to the accompanying drawings.

[0087] like Figure 1-Figure 15 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 .

[0088] 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.

[0089] 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.

[0090] 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.

[0091] The clothing processing drum assembly 2 is rotatably supported on the air duct shell assembly 1 via the 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 via the rotating shaft 23, so the other end of the rotating shaft 23 is rotatably supported on the air duct shell assembly 1.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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 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 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.

[0110] The protection structure 121 may be a flange structure or a curling structure.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] Reference Figure 7-Figure 9 The 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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 and is arranged in the installation space, the rolling bearing includes an outer bearing and an inner bearing, the outer bearing is fixedly arranged in the installation space, and the inner bearing is fixedly connected to the rotating shaft 23, and the first seat body 1111 and the second seat body 1112 are stopped at opposite sides of the outer ring of the rolling bearing, 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 to prevent the rotating shaft 23 from moving in the axial direction relative to the rolling bearing, affecting the stability of the connection of the rotating shaft 23. The inner bearing of the inner ring of the rolling bearing 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.

[0122] In some embodiments, in combination Figure 10-15In the illustrated embodiment, the air duct shell assembly 1 also includes: a reinforcement member 4, and the clothing treatment drum assembly 2 is rotatably connected to the reinforcement member 4. Relying on the high-strength reinforcement member 4, the reinforcement member 4 has a mounting portion 41 and a connecting portion 42. The reinforcement member 4 is used to support the clothing treatment drum assembly 2 to ensure the stability of the clothing treatment drum assembly 2.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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 .

[0132] 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.

[0133] In other embodiments, Figure 1-Figure 6 As shown, the air duct housing 13 includes a separately formed cover 131 and a volute 132, the cover 131 and the volute 132 are sealed together, the cover 131 and the volute 132 are stacked near each other to achieve a sealed fit, and the stacked portion of the cover 131 and the volute 132 can increase the contact area of ​​the seal between the cover 131 and the volute 132, thereby better achieving the seal between the cover 131 and the volute 132. The cover 131 and the volute 132 are both connected to the support plate 12, so as to use the high-strength support plate 12 to strengthen the strength of the cover 131 and the volute 132, and ensure the stability of the cover 131 and the volute 132.

[0134] The cover body 131 and the volute 132 can be made of different materials according to different strength requirements. For example, the cover body 131 is a metal part and the volute 132 is a plastic part. Since the two do not need to be made of the same material, the production cost is reduced and the weight of the dryer is reduced.

[0135] The distance between the portion where the cover body 131 and the volute 132 are stacked and the center of the opening 1011 is less than the radius of the opening 1011, that is, the portion where the cover body 131 and the volute 132 are stacked is located at the rear side of the opening 1011. Since this portion has a simple structure and the portion where the cover body 131 and the volute 132 are stacked is flat, it is beneficial to the sealing between the cover body 131 and the volute 132. In addition, the cover body 131 does not need to cover the entire rear side of the opening 1011. While ensuring that the cover body 131 has sufficient strength to support the clothing processing drum assembly 2 and the cover body 131 can be arranged at the rear side of the center position of the clothing processing drum assembly 2 to support the clothing processing drum assembly 2, the volume of the cover body 131 with a larger material mass is reduced as much as possible, thereby reducing the overall mass of the air duct shell 13, thereby achieving lightweight dryer.

[0136] Furthermore, since the connection between the cover body 131 and the support plate 12 is arranged around the center of the through hole 1011, the distance between each connection and the connection between the cover body 131 and the clothing processing drum assembly 2 is the same, so that each part can be evenly stressed, which is more conducive to the cover body 131 supporting the clothing processing drum assembly 2.

[0137] A volute tongue portion 1321 is formed on the volute 132, and the projection of the volute tongue portion 1321 on the support plate 12 is located between the through-port 1011 and the air outlet 1012. The shape and size of the volute tongue portion 1321 can improve the flow characteristics of the airflow and reduce wind resistance, so that the airflow can flow more smoothly from the air outlet 1012 to the through-port 1011, reducing noise and vibration.

[0138] Since the structure of the volute tongue portion 1321 is relatively complex, by arranging the volute tongue portion 1321 on the volute 132, the processing difficulty of the cover body 131 can be reduced, and the shape of the cover body 131 is uniform, which is conducive to the cover body 131 to more stably support the clothing processing drum assembly 2.

[0139] The clothes processing drum assembly 2 can be supported on the cover body 131 . Since the cover body 131 is made of a relatively high-strength metal material, the cover body 131 can stably support the clothes processing drum assembly 2 .

[0140] The cover body 131 has a placement recess 1311 on the side facing away from the opening 1011, and the bearing seat 111 is arranged in the placement recess 1311. By arranging the placement recess 1311 on the cover body 131, not only can an installation space be provided for the bearing seat 111, but also the matching area between the cover body 131 and the bearing seat 111 can be increased, so that the arrangement of the bearing seat 111 is more stable. Furthermore, it can also avoid that the arrangement of the bearing seat 111 affects the axial size of the overall dryer in the clothing processing drum assembly 2, thereby realizing the miniaturization and lightweight of the dryer.

[0141] Among them, the shape of the bearing seat 111 is adapted to the shape of the placing recess 1311, so that the bearing seat 111 can be completely embedded in the placing recess 1311, and the inner wall of the placing recess 1311 is used to limit the bearing seat 111 to ensure the stability of the setting of the bearing seat 111. It can also avoid the placing recess 1311 occupying too much space to affect the space used for ventilation inside the ventilation cavity 101, and reduce the influence of the setting of the placing recess 1311 on the wind resistance in the ventilation cavity 101.

[0142] Among them, the placement recess 1311 is arranged on the side of the cover body 131 facing away from the through opening 1011, so that the bearing seat 111 can be arranged outside the ventilation cavity 101, 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.

[0143] The bottom wall of the recess 1311 is provided with a through hole 1312 to allow the bearing seat 111 or the rotating shaft 23 to pass through, so as to connect the bearing seat 111 arranged at the rear side of the air duct shell 13 and the clothing processing drum assembly 2 arranged at the front side of the air duct shell 13.
