[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] The following describes a laundry treatment drum assembly 1 of a clothes dryer according to an embodiment of the present utility model with reference to the accompanying drawings.

[0040] like Figure 1-Figure 8 As shown, the laundry treatment drum assembly 1 of the clothes dryer according to the embodiment of the present utility model comprises a drum body 50 and a drum cover 20 .

[0041] The barrel 50 has an open opening at one axial end and a clothing access opening 51 at the other end. The user can place the clothes that need to be dried from the clothing access opening 51 into the inner cavity of the barrel 50. The barrel cover 20 closes the open opening and has a first extension portion 21 extending in a direction away from the clothing access opening 51. The first extension portion 21 defines a first air inlet chamber 210 connected to the inner cavity of the barrel 50. By extending the first extension portion 21 in a direction away from the clothing access opening 51, the first air inlet chamber 210 is connected to the inner cavity of the barrel 50, thereby increasing the volume of the clothing processing chamber 52 defined by the barrel 50 and the barrel cover 20. This facilitates increasing the maximum drying capacity of the dryer. At the same time, by increasing the volume of the clothing processing chamber 52, the contact area between the clothes in the clothing processing chamber 52 and the air is increased, thereby facilitating improving the efficiency of drying the clothes.

[0042] Among them, the first extension portion 21 includes an end wall 23 and a peripheral wall 24. The end wall 23 is arranged opposite to the clothing access port 51. The end wall 23 is provided with a plurality of first ventilation portions 21 arranged at intervals in the circumferential direction of a circle. Each first ventilation portion 21 includes a plurality of first ventilation holes 211 arranged in a radial spiral on the circumference. External air can enter the clothing processing chamber 52 in the direction toward the clothing access port 51 through the plurality of first through-hole portions on the end wall 23 to dry the clothes in the clothing processing chamber 52.

[0043] Since the end wall 23 is arranged opposite to the clothing access opening 51, the first ventilation portion 21 on the end wall 23 will be exposed from the clothing access opening 51, so that the multiple first ventilation holes 211 are arranged in a radial spiral on the circumference, which facilitates improving the aesthetics of the arrangement of the first ventilation portion 21 on the end wall 23, thereby improving the aesthetics of the dryer.

[0044] In addition, when the clothes processing drum assembly 1 rotates, the plurality of first ventilation holes 211 arranged in a radial spiral on the circumference can form a dynamic visual effect, further improving the aesthetics of the clothes dryer.

[0045] Among them, multiple first ventilation parts 21 are arranged at intervals in the circumferential direction of a circle, and multiple first ventilation holes 211 of each first ventilation part 21 are arranged in a radial spiral on the circumference. Such a configuration can enable the multiple first ventilation holes 211 to be arranged in an orderly manner. When the airflow enters the clothing processing chamber 52 from the first ventilation part 21, the uniformity of the air intake of the clothing processing chamber 52 in its circumferential direction can be further guaranteed, thereby further improving the drying effect.

[0046] It can be understood that the plurality of first ventilation holes 211 are arranged densely near the middle of the drum cover 20 and sparsely at a position away from the middle of the drum cover 20. Therefore, in order to ensure the uniformity of air intake of the laundry processing chamber 52 in its radial direction, the size of the first ventilation holes 211 near the middle of the drum cover 20 can be set to be smaller, and the size of the first ventilation holes 211 away from the middle of the drum cover 20 can be set to be larger. Of course, the shapes and sizes of the plurality of first ventilation holes 211 in each first ventilation portion 21 can also be set to be the same.

[0047] The peripheral wall 24 surrounds the end wall 23, and a second ventilation portion 22 is provided on the peripheral wall 24. External air can enter the clothing processing chamber 52 through the second ventilation portion 22 on the peripheral wall 24 to dry the clothes in the clothing processing chamber 52. Specifically, when the clothing processing drum assembly 1 rotates, under the action of centrifugal force, the clothes in the clothing processing chamber 52 are easily attached to the inner wall of the clothing processing chamber 52, while the clothes attached to the inner wall of the clothing processing chamber 52 are not easy to be dried. This results in that when drying clothes, some areas of the clothes can never be dried and are always wet.

[0048] The present application provides a second ventilation portion 22 on the peripheral wall 24 so that air enters the clothing processing chamber 52 from the second ventilation portion 22 on the peripheral wall 24. In this way, when the air enters the clothing processing chamber 52, it can first come into contact with the clothing attached to the peripheral wall 24 so as to dry the portion of the clothing attached to the peripheral wall 24. This, on the one hand, facilitates increasing the air intake of the clothing processing chamber 52 and improving the drying efficiency of the clothing in the clothing processing chamber 52. On the other hand, it can fully dry the clothing in the clothing processing chamber 52 and reduce the probability of some areas of the clothing failing to be dried, thereby improving the drying effect of the dryer and improving the user experience.

[0049] In addition, allowing air to enter the clothing processing chamber 52 from the first ventilation portion 21 on the end wall 23 and the second ventilation portion 22 on the peripheral wall 24 is convenient for increasing the air intake of the clothing processing chamber 52 on the one hand, and for allowing air to enter the clothing processing chamber 52 evenly on the other hand, so that the clothes in the clothing processing chamber 52 can be dried sufficiently and evenly.

[0050] According to the clothing processing drum assembly 1 of the dryer according to the embodiment of the utility model, by arranging the second ventilation part 22 on the peripheral wall 24, the air entering the clothing processing chamber 52 from the second ventilation part 22 can directly contact the clothing attached to the peripheral wall 24, so as to directly dry this part of the clothing, thereby reducing the probability of partial areas of the clothing not being able to be dried, thereby improving the drying effect of the dryer and improving the user experience.

[0051] The following describes a laundry treatment drum assembly 1 of a clothes dryer according to a specific embodiment of the present utility model with reference to the accompanying drawings.

[0052] In some specific embodiments of the present invention, Figure 1-Figure 8 As shown, the laundry treatment drum assembly 1 of the clothes dryer includes a drum body 50 and a drum cover 20 .

[0053] In some embodiments of the present invention, the first ventilation hole 211 is formed into a polygonal hole. For example, the first ventilation hole 211 can be formed into a triangular hole, a quadrilateral hole, a hexagonal hole, etc. In this way, while ensuring the air intake, a part of the sound waves can be blocked to achieve noise reduction.

[0054] Of course, the first ventilation hole 211 may also be a circular hole, an elliptical hole, etc., which can be selected according to actual conditions.

[0055] In some embodiments of the present invention, Figure 4 As shown, the peripheral wall 24 gradually extends outward in a direction close to the clothing access opening 51 so that external air can smoothly enter the first air inlet cavity 210 and the inner cavity of the barrel 50 from the second ventilation portion 22 to dry the clothing attached to the peripheral wall 24 .

[0056] like Figure 4 As shown, in the present embodiment, the air in the external environment flows from the back to the front, the clothing access opening 51 is located at the front side of the drum cover 20, and in the direction from the back to the front, the peripheral wall 24 gradually extends outwardly at an angle (it should be understood here that the above-mentioned direction limitation is only for the convenience of describing the accompanying drawings, and will not limit the actual setting position and direction of the clothing processing drum assembly 1 of the dryer), and the air enters the first air inlet chamber 210 from the first ventilation portion 21 and the second ventilation portion 22 from the back to the front. If the peripheral wall 24 extends in the front-to-back direction and the peripheral wall 24 is parallel to the flow direction of the air, it will cause the external air to be difficult to enter the first air inlet chamber 210 through the second ventilation portion 22 on the peripheral wall 24. Therefore, the peripheral wall 24 is gradually extended outward in the direction close to the clothing access opening 51, so that the air can enter the first air inlet chamber 210 through the second ventilation portion 22 on the peripheral wall 24 during the flow process, and then the clothes attached to the peripheral wall 24 are dried, so as to reduce the drying dead corners of the clothes, improve the drying effect, and avoid the situation where some areas of the clothes are still wet when the dryer stops working.

[0057] It should be explained here that the inside and outside are relative to the axis of the barrel 50. The side of the peripheral wall 24 close to the axis of the barrel 50 is the inner side, and the side of the peripheral wall 24 away from the axis of the barrel 50 is the outer side.

[0058] In some embodiments of the present invention, Figure 4 As shown, the second ventilation portion 22 includes a plurality of second ventilation holes 221 arranged at intervals in the circumferential direction of the end wall 23 , and air enters the first air inlet chamber 210 through the plurality of second ventilation holes 221 to dry the clothes in the inner cavity of the barrel 50 .

[0059] Among them, the second ventilation hole 221 has a pressurizing effect on the air, so that the air flowing into the barrel 30 has a stronger penetrating ability, thereby being able to achieve the effect of penetrating and drying the clothes.

[0060] In some embodiments, the second ventilation hole 221 forms a polygonal hole. For example, the second ventilation hole 221 can form a triangular hole, a quadrilateral hole, a hexagonal hole, etc. In this way, while ensuring the air intake, a part of the sound waves can be blocked to achieve noise reduction.

[0061] Of course, the second ventilation hole 221 may also be a circular hole, an elliptical hole, etc., which can be selected according to actual conditions.

[0062] In some embodiments of the present invention, the number of the second ventilation portion 22 is one, and air enters the first air inlet cavity 210 through the second ventilation portion 22 to dry the clothes in the inner cavity of the barrel 50 .

[0063] In some embodiments, the second ventilation portion 22 includes a plurality of second ventilation holes 221 arranged at intervals in the circumferential direction of the end wall 23 .

[0064] In other embodiments of the present invention, Figure 4 As shown, there are multiple second ventilation parts 22 and the multiple second ventilation parts 22 are arranged axially in the drum cover 20. Air can enter the first air inlet cavity 210 through the multiple second ventilation parts 22 to dry the clothes in the inner cavity of the drum body 50.

[0065] like Figure 4 As shown, in the present embodiment, a plurality of second ventilation portions 22 are arranged along the axial direction of the cylinder cover 20, and the second ventilation portions 22 include a plurality of second ventilation holes 221 arranged at intervals in the circumferential direction of the end wall 23, and the second ventilation holes 221 in two adjacent second ventilation portions 22 are staggered in the axial direction of the cylinder cover 20, so as to reasonably arrange the plurality of first ventilation holes 211 in a limited space, thereby increasing the air intake volume.

[0066] In some embodiments, the peripheral wall 24 is a sheet metal part, and a plurality of second ventilation holes 221 can be formed on the peripheral wall 24 by stamping on the peripheral wall 24, so that the second ventilation holes 221 in two adjacent second ventilation parts 22 are staggered in the axial direction of the cylinder cover 20, so that there is a sufficient distance between two adjacent second ventilation holes 221 in the axial direction of the cylinder cover 20, thereby facilitating the strength of the peripheral wall 24.

[0067] In some embodiments of the present invention, Figure 5 , Figure 6 As shown, the end wall 23 includes a first wall body 231, which extends from the outside to the inside in a direction close to the clothing access port 51, and the first ventilation portion 21 is arranged on the first wall body 231, so as to increase the area of ​​the first wall body 231, and then increase the area of ​​the first ventilation portion 21 on the first wall body 231, so as to increase the air intake and allow the air to enter the first chamber evenly from the first ventilation portion 21.

[0068] In addition, the first wall 231 is extended from the outside toward the direction close to the clothing access opening 51 to prevent the length of the clothing treatment drum assembly 1 in the axial direction of the drum body 50 from being too long, thereby preventing the size of the dryer from being too large.

[0069] In some optional embodiments of the present invention, Figure 5 As shown, the end wall 23 also includes a second wall body 232, and the first wall body 231 is located on the outer periphery of the second wall body 232 and connects the second wall body 232 and the peripheral wall 24, so that the second wall body 232 is located on the inner side of the first wall body 231 to form a plane on the inner side of the second wall body 232 to avoid forming a cone angle at the inner end of the second wall body 232 to avoid the cone angle from hooking the clothes in the inner cavity of the barrel 50.

[0070] In some specific embodiments of the present invention, the first wall 231 is connected to the peripheral wall 24 by an arc transition to ensure a smooth transition between the first wall 231 and the peripheral wall 24, thereby avoiding a sharp angle between the first wall 231 and the peripheral wall 24 to prevent the angle from hooking the clothes in the inner cavity of the barrel 50.

[0071] In some specific embodiments of the present invention, the first wall 231 and the second wall 232 are connected in an arc transition to ensure a smooth transition between the first wall 231 and the second wall 232, thereby avoiding a sharp angle between the first wall 231 and the second wall 232 to prevent the angle from hooking the clothes in the inner cavity of the barrel 50.

[0072] In some specific embodiments of the present invention, Figure 7 , Figure 8As shown, a vent 25 is provided on the second wall 232, and the clothing processing drum assembly 1 also includes an air guide hood 30, which is provided on the inner side of the drum cover 20 and defines an air passage cavity 35 between the air guide hood 30 and the second wall 232, and the air guide hood 30 is provided with a plurality of third external ventilation parts arranged at circumferential intervals on a circle, and the third external ventilation parts are connected to the air passage cavity 35 and the first air inlet cavity 210, and the air in the external environment can enter the air passage cavity 35 through the vent 25 on the second wall 232, and enter the first air inlet cavity 210 through the third external ventilation parts, so as to realize the drying treatment of the clothes in the inner cavity of the drum body 50.

[0073] Among them, by arranging the first ventilation part 21 on the first wall 231, the second ventilation part 22 on the peripheral wall 24, and the ventilation holes on the second wall 232, air can enter the first air inlet chamber 210 from different positions of the drum cover 20, thereby realizing the drying treatment of the clothes in the drum body 50. This is convenient for increasing the air intake volume of the clothing processing drum assembly 1 on the one hand, and for realizing uniform air intake on the other hand, so that the air can enter the drum body 50 evenly, so as to fully dry the clothes in the drum body 50.

[0074] In some embodiments, Figure 6 As shown, the air guide cover 30 is arranged on the side of the second wall 232 facing the clothing access port 51 and is spaced apart from the second wall 232 in the axial direction of the cylinder body 50 to define an air passage cavity 35, so as to prevent the air guide cover 30 from blocking the ventilation port 25, thereby facilitating increasing the air intake.

[0075] In some embodiments, the drum body 50 and the drum cover 20 define a clothes processing chamber 52, and the second wall 232 is located in the central area of ​​the drum cover 20. When the dryer is working, the airflow can enter the air chamber 35 from the vent 25, and then enter the clothes processing chamber 52 through the third external ventilation part. The airflow flowing out of the third external ventilation part can flow into the clothes processing chamber 52 under the guidance of the air guide cover 30, thereby concentrating the airflow, so that the airflow in the clothes processing chamber 52 forms a high wind pressure with strong penetration ability, and achieves the effect of central penetration drying. In addition, the air guide cover 30 can change the flow direction of the airflow, so that the air intake of the clothes processing chamber 52 is more uniform, further improving the drying effect.

[0076] Therefore, by setting the air guide cover 30 at the second wall 232, the air intake form in the clothing processing chamber 52 can be improved, the wind pressure of the air intake in the central area of ​​the drum cover 20 can be increased, and the effect of center penetration drying can be achieved, which is convenient for improving the drying effect and enhancing the user experience.

[0077] In some embodiments, the side of the second wall 232 facing away from the clothing access opening 51 is used to install the rotating shaft 61, and the rotating shaft 61 is used to cooperate with the driving member of the dryer to drive the clothing processing drum assembly 1 to rotate to achieve uniform drying of the clothing.

[0078] In some embodiments, a plurality of vents 25 are provided on the second wall 232, and the plurality of vents 25 are arranged at intervals around a circle, wherein a rotating shaft 61 is provided on the side of the second wall 232 facing away from the clothing access port 51, and the rotating shaft 61 is used to cooperate with the motor so that the motor drives the clothing processing drum assembly 1 to rotate, so that the dryer can dry the clothes evenly. The plurality of vents 25 are arranged circumferentially around the rotating shaft 61, so as to reserve a position for the rotating shaft 61 while maximizing the ventilation area, thereby facilitating increasing the air intake into the inner cavity of the drum body 50.

[0079] In some examples, such as Fig. 9 , Fig.10 As shown, one end of the rotating shaft 61 is fixedly connected to the second wall 232 through a fixed bracket 62, and the other end of the rotating shaft 61 is supported on the air duct shell assembly 70 of the dryer through a bearing 63. Thus, the rotating shaft 61 is rotatably connected to the air duct shell assembly 70, and the clothing processing drum assembly 1 is rotatably supported and arranged on the air duct shell assembly 70.

[0080] In other examples, the rotating shaft 61 is fixed to the second wall body 232, for example, the rotating shaft 61 and the second wall body 232 are an integrally formed part, and the other end of the rotating shaft 61 is supported on the air duct shell assembly 70 of the dryer through a bearing 63, thereby, the rotating shaft 61 is rotatably connected to the air duct shell assembly 70, and the clothing processing drum assembly 1 is rotatably supported and set on the air duct shell assembly 70.

[0081] In some specific embodiments of the present invention, Figure 2 , Figure 3 As shown, a plurality of third external ventilation parts are arranged at intervals in the circumferential direction of a circle, and each third external ventilation part includes a plurality of third external ventilation holes 331 arranged at intervals in the radial direction along the circumference. Such arrangement can enable the plurality of third external ventilation holes 331 to be arranged in an orderly manner. When the airflow enters the air cavity 35 from the vent 25, it can enter the inner cavity of the barrel 50 from the plurality of third external ventilation holes 331, thereby further ensuring the uniformity of air intake in the inner cavity of the barrel 50 in its circumferential direction and further improving the drying effect.

[0082] In some embodiments, the third outer vent 331 is formed into a polygonal hole. For example, the third outer vent 331 can be formed into a triangular hole, a quadrilateral hole, a hexagonal hole, etc. In this way, while ensuring the air intake, a part of the sound waves can be blocked to achieve noise reduction.

[0083] Of course, the third external ventilation hole 331 can also be a circular hole, an elliptical hole, etc., which can be selected according to actual conditions.

[0084] In some specific embodiments of the present invention, Figure 2 , Figure 3As shown, a plurality of third external ventilation parts are arranged at intervals in the circumferential direction of a circle, and the number of the plurality of third external ventilation parts and the plurality of first ventilation parts 21 are equal and their positions correspond one to one. In this way, on one hand, the consistency of the arrangement of the plurality of third external ventilation parts and the plurality of first ventilation parts 21 can be ensured, which is beneficial to improving the visual experience. On the other hand, the plurality of third external ventilation parts are equivalent to the continuation structure of the plurality of first ventilation parts 21, which can further ensure the uniformity of the air intake of the inner cavity of the barrel 50 in its circumferential direction, and further improve the drying effect.

[0085] In some embodiments, the first ventilation portion 21 includes a plurality of first ventilation holes 211 arranged in a radial spiral on the circumference, and the third external ventilation portion includes a plurality of third external ventilation holes 331 arranged in a radial spiral on the circumference. It can be understood that the first ventilation holes 211 and the third external ventilation holes 331 are arranged more densely near the middle of the barrel cover 20, and are arranged more sparsely at positions away from the middle of the barrel cover 20, thereby ensuring the uniformity of air intake in the inner cavity of the barrel body 50 in its radial direction.

[0086] In some examples, in each third external ventilation portion, the flow areas of the plurality of third external ventilation holes 331 increase sequentially from the inside to the outside, that is, the size of the third external ventilation holes 331 close to the middle of the barrel cover 20 can be set to be smaller, and the size of the third external ventilation holes 331 away from the middle of the barrel cover 20 can be set to be larger.

[0087] Of course, the shapes and sizes of the multiple third external ventilation holes 331 in each third external ventilation portion can also be set to be the same; or, the flow areas of the multiple third external ventilation holes 331 in each third external ventilation portion increase sequentially from the outside to the inside.

[0088] In some specific embodiments of the present invention, Figure 2 , Figure 3 As shown, the air guide cover 30 includes a middle cover portion 31 and an annular cover portion 32. The annular cover portion 32 surrounds the outer side of the middle cover portion 31. The inner circle of the annular cover portion 32 is connected to the middle cover portion 31 and the outer circle is in contact with the end wall 23. The annular cover portion 32 extends from the outside to the inside in a direction close to the clothing access opening 51. The third external ventilation portion is provided on the annular cover portion 32. The airflow entering the inner cavity of the barrel 50 from the multiple third external ventilation portions on the annular cover portion 32 can change the air intake direction under the guidance of the annular cover portion 32, so that the airflow can fill the inner cavity of the barrel 50, thereby making the air intake of the inner cavity of the barrel 50 more uniform, further improving the drying effect of the clothes dryer.

[0089] In some embodiments, Figure 2 , Figure 3As shown, the middle cover portion 31 is provided with a third inner ventilation portion, and the third inner ventilation portion includes a plurality of third inner ventilation holes 341 arranged at intervals. The airflow entering the inner cavity of the barrel 50 from the plurality of third inner ventilation holes 341 on the middle cover portion 31 can be gathered together to form a high wind pressure with strong penetrating ability, thereby achieving the effect of center penetration drying and solving the problem of the center of the clothes being wrapped but not dried thoroughly. The airflow entering the inner cavity of the barrel 50 from the plurality of third outer ventilation portions on the annular cover portion 32 can change the air intake direction under the guidance of the annular cover portion 32, so that the airflow can fill the inner cavity of the barrel 50, thereby making the air intake in the inner cavity of the barrel 50 more uniform, further improving the drying effect of the dryer.

[0090] like Figure 3 , Figure 6 As shown, in some embodiments, the outer surface of the annular cover portion 32 forms a concave arc surface. Specifically, the outer surface of the annular cover portion 32 forms a concave arc surface extending from the outside to the inside toward the open opening of the clothing processing chamber 52. In this way, on the one hand, the airflow in the air passage cavity 35 can flow toward the direction close to the clothing access opening 51 under the guidance of the annular cover portion 32, thereby increasing the wind speed of the middle airflow in the inner cavity of the cylinder body 50, thereby forming a high wind pressure with strong penetration ability, which is conducive to achieving the effect of center penetration drying. On the other hand, the air inlet direction of the third external ventilation hole 331 can be changed, so that the airflow can fill the inner cavity of the cylinder body 50, so that the air enters the inner cavity of the cylinder body 50 more evenly, further improving the drying effect of the clothes dryer.

[0091] In addition, when part of the air can flow along the outer surface of the annular cover portion 32 toward the middle cover portion 31, the concave arc surface on the outer surface of the annular cover portion 32 has a gathering effect on the air, so as to increase the air intake of the third inner ventilation portion at the middle cover portion 31, and then the airflow can be gathered together at the middle cover portion 31, so that the air enters the inner cavity of the cylinder body 50 from the third inner ventilation hole 341 with a higher wind pressure, thereby achieving the effect of center penetration drying.

[0092] In some examples, the middle cover portion 31 and the annular cover portion 32 are integrally formed. By integrally forming the middle cover portion 31 and the annular cover portion 32, not only can the number of parts be reduced, and the connection structure for connecting the middle cover portion 31 and the annular cover portion 32 is omitted, but also the molding is more convenient, which is conducive to improving the connection reliability of the middle cover portion 31 and the annular cover portion 32 and improving the production efficiency.

[0093] In some embodiments of the utility model, the ratio of the total ventilation volume at the end wall 23 to the total ventilation volume at the drum cover 20 is greater than 0.3 and less than 1, or equal to 0.3, so as to ensure the air intake into the middle part of the inner cavity of the drum body 50, thereby ensuring the drying of the clothes in the middle part of the inner cavity of the drum body 50 and ensuring the drying effect of the center of the dryer.

[0094] Specifically, the total ventilation volume at the end is used to ensure air intake to the middle of the barrel 50, and to ensure the central drying effect of the dryer. The total ventilation volume at the peripheral wall 24 is used to ensure air intake to the peripheral wall 24 of the barrel 50, so as to reduce the drying dead corners, and thus fully dry the part of the clothes attached to the peripheral wall 24 of the barrel 50, so that the ratio of the total ventilation volume at the end wall 23 to the total ventilation volume at the barrel cover 20 is greater than 0.3 and less than 1, or equal to 0.3, that is, the ratio of the total ventilation volume at the peripheral wall 24 to the total ventilation volume at the barrel cover 20 is greater than 0 and less than 0.7, or equal to 0.7, so as to simultaneously ensure that the dryer has a good central drying effect and a drying effect on the clothes attached to the peripheral wall 24 of the barrel 50.

[0095] Among them, when the ratio of the total ventilation volume at the end wall 23 to the total ventilation volume at the cylinder cover 20 is 0.3, the ratio of the total ventilation volume at the peripheral wall 24 to the total ventilation volume at the cylinder cover 20 is 0.7; correspondingly, when the ratio of the total ventilation volume at the end wall 23 to the total ventilation volume at the cylinder cover 20 is 0.5, the ratio of the total ventilation volume at the peripheral wall 24 to the total ventilation volume at the cylinder cover 20 is 0.5; when the ratio of the total ventilation volume at the end wall 23 to the total ventilation volume at the cylinder cover 20 is 0.8, the ratio of the total ventilation volume at the peripheral wall 24 to the total ventilation volume at the cylinder cover 20 is 0.2.

[0096] In some embodiments of the present invention, Figure 4 As shown, the drum cover 20 also has a second extension portion 26 extending in a direction away from the clothing taking-in and putting-out port 51, the second extension portion 26 is located between the first extension portion 21 and the drum body 50, and the first extension portion 21 extends in a direction away from the clothing taking-in and putting-out port 51 relative to the second extension portion 26, wherein the second extension portion 26 defines a second air inlet chamber 260, and the second air inlet chamber 260 is connected between the first air inlet chamber 210 and the inner cavity of the drum body 50, and a clothing processing chamber 52 is defined between the drum cover 20 and the drum body 50. By providing the second extension portion 26, the volume of the clothing processing chamber 52 can be increased, thereby facilitating the increase of the maximum drying capacity of the dryer, and at the same time, by increasing the volume of the clothing processing chamber 52, the contact area between the clothing in the clothing processing chamber 52 and the air can be increased, thereby facilitating the improvement of the efficiency of the clothing drying process.

[0097] In some embodiments, the second extension portion 26 is a non-porous structure, and the second extension portion 26 can separate the clothing treatment drum assembly 1 from the air duct shell assembly 70 of the dryer to avoid interference between the clothing treatment drum assembly 1 and the air duct shell assembly 70 during rotation.

[0098] In some embodiments of the utility model, the barrel cover 20 is an integrally formed metal part, that is, the end wall 23 and the peripheral wall 24 are an integrally formed metal part. This not only reduces the number of components and eliminates the connection structure for connecting the end wall 23 and the peripheral wall 24, but also makes molding more convenient, which is beneficial to improving the connection reliability between the end wall 23 and the peripheral wall 24 and improving production efficiency.

[0099] In some embodiments, the end wall 23 includes a first wall body 231 and a second wall body 232, the first wall body 231 connects the second wall body 232 and the peripheral wall 24, and the barrel cover 20 also has a second extension portion 26 extending in a direction away from the clothing access port 51, wherein, from the outside to the inside, they are the second extension portion 26, the peripheral wall 24, the first wall body 231 and the second wall body 232, and the second extension portion 26, the peripheral wall 24, the first wall body 231 and the second wall body 232 are an integrally formed metal part.

[0101] The air duct shell assembly 70 defines a ventilation cavity 71 with an opening on one side, the barrel cover 20 covers the opening and the first extension portion 21 extends into the ventilation cavity 71 from the opening, the first ventilation portion 21 and the second ventilation portion 22 are both connected to the first air inlet cavity 210 and the ventilation cavity 71, and the air in the ventilation cavity 71 enters the inner cavity of the barrel body 50 through the opening from the first ventilation portion 21 and the second ventilation portion 22 on the first extension portion 21 to dry the clothes in the inner cavity of the barrel body 50.

[0102] Among them, the drum cover 20 and the drum body 50 define a clothing processing chamber 52, so that the first extension portion 21 extends from the opening into the ventilation chamber 71. The capacity of the clothing processing chamber 52 is no longer limited by the space limitation behind the air duct shell assembly 70, thereby increasing the capacity of the clothing processing chamber 52.

[0103] According to the dryer according to the embodiment of the utility model, by utilizing the clothing processing drum assembly 1 of the dryer according to the above-mentioned embodiment of the utility model, by arranging the second ventilation part 22 on the peripheral wall 24, the air entering the clothing processing chamber 52 from the second ventilation part 22 can directly contact the clothing attached to the peripheral wall 24, so as to directly dry this part of the clothing, thereby reducing the probability of partial areas of the clothing not being able to be dried, thereby improving the drying effect of the dryer and improving the user experience.

[0104] In some embodiments of the utility model, the barrel cover 20 has a sealing protrusion located on the outer periphery of the end wall 23, and the sealing protrusion is sealed with the air duct shell assembly 70 to seal the gap between the air duct shell assembly 70 and the barrel cover 20, thereby ensuring the sealing of the cooperation between the two, so that the air in the ventilation cavity 71 can smoothly enter the inner cavity of the barrel body 50 from the first ventilation portion 21 and the second ventilation portion 22 on the first extension portion 21 through the opening.

[0105] In some embodiments, the sealing protrusion is located on the outer side of the first extension portion 21 , and when the first extension portion 21 extends into the ventilation cavity 71 , the sealing protrusion is sealed and matched with the air duct shell assembly 70 .

[0106] In some embodiments of the present invention, the drum cover 20 is rotatably supported on the air duct shell assembly 70 via the rotating shaft 61, so that the clothing processing drum assembly 1 can rotate relative to the air duct shell assembly 70 to achieve uniform drying of the clothing.

[0107] In some examples, such as Fig. 9 , Fig.10 As shown, one end of the rotating shaft 61 is fixedly connected to the second wall 232 through a fixed bracket 62, and the other end of the rotating shaft 61 is supported on the air duct shell assembly 70 of the dryer through a bearing 63. Thus, the rotating shaft 61 is rotatably connected to the air duct shell assembly 70, and the clothing processing drum assembly 1 is rotatably supported and arranged on the air duct shell assembly 70 to achieve uniform drying of the clothing.
