[0043] 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.

[0044] 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.

[0045] like Figure 1-Figure 5 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 30 and a drum cover 10 .

[0046] The barrel 30 has an open opening at one axial end and a clothing access opening 31 at the other end. The user can place the clothes that need to be dried into the inner cavity of the barrel 30 from the clothing access opening 31. The barrel cover 10 closes the open opening and has a first extension portion 11 extending in a direction away from the clothing access opening 31. The first extension portion 11 defines a first air inlet chamber 110 connected to the inner cavity of the barrel 30. By extending the first extension portion 11 in a direction away from the clothing access opening 31, the first air inlet chamber 110 is connected to the inner cavity of the barrel 30, thereby increasing the volume of the clothing processing chamber 32 defined by the barrel 30 and the barrel cover 10. This facilitates increasing the maximum drying capacity of the dryer. At the same time, by increasing the volume of the clothing processing chamber 32, the contact area between the clothes in the clothing processing chamber 32 and the air is increased, thereby facilitating improving the efficiency of drying the clothes.

[0047] Among them, the barrel cover 10 includes a separately molded cover body 12 and a ventilation hood 13, the cover body 12 is provided with a mounting port 121 and a plurality of first ventilation holes 123, the ventilation hood 13 is arranged on the cover body 12 and covers the mounting port 121, the ventilation hood 13 is provided with a plurality of second ventilation holes 133, the first ventilation holes 123 and the second ventilation holes 133 are both connected to the first air inlet chamber 110, and external air can enter the inner cavity of the barrel body 30 through the first ventilation holes 123 and the second ventilation holes 133 to dry the clothes in the clothing processing chamber 32.

[0048] It can be understood that the number of mounting openings 121 on the cover body 12 is much smaller than the total number of second ventilation holes 133 on the multiple ventilation hoods 13, and the size of the mounting openings 121 is also larger than the size of the second ventilation holes 133. If multiple small holes are directly processed on the cover body 12, due to the large size of the cover body 12 and the large number of small holes, this method of processing is more difficult and has a higher processing cost.

[0049] The utility model forms a plurality of relatively large mounting openings 121 on the cover body 12, arranges the ventilation hood 13 at the mounting openings 121, and provides a plurality of second ventilation holes 133 arranged at intervals on the ventilation hood 13. In this way, the ventilation hood 13 and the cover body 12 can be made of different materials, and the size of the ventilation hood 13 is smaller than that of the cover body 12. It is relatively easy to form the plurality of second ventilation holes 133 on the ventilation hood 13. Therefore, compared with the solution of directly machining a plurality of small holes on the cover body 12, the present solution is less difficult to machine and is convenient for reducing the machining cost.

[0050] In addition, a plurality of first ventilation holes 123 are arranged on the cover body 12, and a plurality of second ventilation holes 133 are arranged on the mounting cover. On the one hand, this facilitates increasing the amount of air intake, and on the other hand, it enables the air to evenly pass through the plurality of first ventilation holes 123 and the plurality of second ventilation holes 133 into the inner cavity of the barrel 30, thereby facilitating uniform drying of the clothes in the inner cavity of the barrel 30.

[0051] According to the laundry processing drum assembly 1 of the dryer in the embodiment of the utility model, a plurality of relatively large mounting openings 121 are provided on the cover body 12, and the ventilation hood 13 is arranged at the mounting openings 121, so as to reduce the difficulty of processing the cover body 12 and further reduce the production cost of the drum cover 10.

[0052] Therefore, according to the embodiment of the utility model, the clothing processing drum assembly 1 of the dryer is provided with a plurality of relatively large mounting openings 121 on the cover body 12, and the ventilation hood 13 is arranged at the mounting openings 121, so as to reduce the difficulty of processing the cover body 12 and thereby reduce the production cost of the drum cover 10.

[0053] 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.

[0054] In some specific embodiments of the present invention, Figure 1-Figure 5 As shown, the laundry treatment tub assembly 1 includes a tub body 30 and a tub cover 10 .

[0055] In some embodiments of the present invention, Figure 1 As shown, the first extension portion 11 includes an end wall 111 arranged opposite to the clothing access port 31, and a peripheral wall 112 surrounding the end wall 111, wherein a plurality of first ventilation holes 123 are arranged on the peripheral wall 112, and the mounting port 121 is arranged on the end wall 111, so as to facilitate the air intake from different directions of the inner cavity of the barrel 30, thereby facilitating the reduction of drying dead corners and improving the drying effect.

[0056] Specifically, the clothing processing chamber 32 defined by the barrel body 30 and the barrel cover 10, and the cover body 12 defines a first extension portion 11 extending in a direction away from the clothing access port 31. The first extension portion 11 is provided to increase the volume of the clothing processing chamber 32, and the mounting port 121 is provided on the end wall 111 so that air can enter the clothing processing chamber 32 from the second ventilation hole 133 in the axial direction of the barrel body 30, and a plurality of first ventilation holes 123 are provided on the peripheral wall 112 so that air can enter the clothing processing chamber 32 from the first ventilation holes 123 in the circumferential direction of the barrel body 30. This, on the one hand, facilitates increasing the air intake of the clothing processing chamber 32 so as to fully dry the clothes in the clothing processing chamber 32, and on the other hand, facilitates the air to enter the clothing processing chamber 32 from different directions of the barrel body 30 so as to reduce drying dead corners and improve the drying effect.

[0057] Among them, when the clothing processing drum assembly 1 rotates, under the action of centrifugal force, the clothes in the clothing processing chamber 32 are easily stuck to the inner wall of the clothing processing chamber 32, and the clothes stuck to the inner wall of the clothing processing chamber 32 are not easy to be dried, which causes that when drying clothes, some areas of the clothes can never be dried and are always wet. By arranging the first ventilation hole 123 on the peripheral wall 112, it is convenient to realize the air intake of the clothing processing chamber 32 in its circumferential direction, so that the air can dry the clothes stuck to the inner wall of the clothing processing chamber 32, which is convenient to reduce the drying dead angle and improve the drying effect of the dryer.

[0058] In some optional embodiments of the present invention, Figure 5 As shown, the peripheral wall 112 is provided with at least one ventilation hole group 124, and the ventilation hole group 124 includes a plurality of first ventilation holes 123. The plurality of first ventilation holes 123 of each ventilation hole group 124 are arranged at intervals in the circumferential direction of the end wall 111. Air can enter the first air inlet chamber 110 through the plurality of first ventilation holes 123 to dry the clothes in the inner cavity of the barrel 30.

[0059] In some specific embodiments of the present invention, Figure 5 As shown, there are multiple ventilation hole groups 124, and the multiple ventilation hole groups 124 are arranged at intervals in the axial direction of the peripheral wall 112. The first ventilation holes 123 in two adjacent ventilation hole groups 124 are staggered in the axial direction of the peripheral wall 112, so as to reasonably arrange the multiple first ventilation holes 123 in a limited space, thereby increasing the air intake.

[0060] In some embodiments, the peripheral wall 112 is a sheet metal part, and a plurality of first ventilation holes 123 can be formed on the peripheral wall 112 by stamping the peripheral wall 112, so that the first ventilation holes 123 in two adjacent ventilation hole groups 124 are staggered in the axial direction of the peripheral wall 112, so that there is a sufficient distance between two adjacent second ventilation holes 133 in the axial direction of the barrel cover 10, thereby facilitating the strength of the peripheral wall 112.

[0061] In some embodiments, the first ventilation hole 123 forms a polygonal hole. For example, the first ventilation hole 123 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.

[0062] In some optional embodiments of the present invention, Fig. 9 As shown, the peripheral wall 112 extends outward in a direction close to the clothing access opening 31 so that external air can smoothly enter the inner cavity of the barrel 30 from the first ventilation hole 123 on the peripheral wall 112 to dry the clothing attached to the peripheral wall 112 .

[0063] like Fig. 9 As shown, in this embodiment, the air in the external environment flows from the back to the front, the clothing access opening 31 is located at the front side of the drum cover 10, and in the direction from the back to the front, the peripheral wall 112 gradually extends outwardly and tilts, and the air enters the first air inlet chamber 110 from the first ventilation hole 123 and the second ventilation hole 133 from the back to the front. If the peripheral wall 112 extends in the front-to-back direction (it should be understood here that the above-mentioned direction limitation is only for the convenience of describing the drawings and will not limit the actual setting position and direction of the clothing processing drum assembly 1 of the dryer), the peripheral wall 112 is parallel to the flow direction of air, which will make it difficult for external air to enter the first air inlet chamber 110 through the first ventilation holes 123 on the peripheral wall 112. Therefore, the peripheral wall 112 is gradually extended outward in the direction close to the clothing access port 31, so that air can enter the first air inlet chamber 110 through the first ventilation holes 123 on the peripheral wall 112 during the flow process, and then dry the clothes attached to the peripheral wall 112, so as to reduce the drying dead corners of the clothes and avoid the situation where some areas of the clothes are still wet when the dryer stops working.

[0064] It should be explained here that the inside and outside are relative to the axis of the barrel 30. The side of the peripheral wall 112 close to the axis of the barrel 30 is the inner side, and the side of the peripheral wall 112 away from the axis of the barrel 30 is the outer side.

[0065] In some optional embodiments of the present invention, Figure 1 , Fig. 9 As shown, the portion of the cover body 12 at the end wall 111 includes a middle portion 127 and a ventilation portion 128, wherein the ventilation portion 128 is located at the periphery of the middle portion 127 and connects the middle portion 127 and the peripheral wall 112, and the mounting port 121 is opened in the ventilation portion 128, wherein at least a portion of the ventilation portion 128 extends from its radial middle portion to one or both sides thereof in a radial direction away from the clothing access port 31, thereby increasing the area of ​​the ventilation portion 128, thereby facilitating an increase in the size of the mounting port 121, increasing the amount of air intake into the inner cavity of the barrel body 30, and at the same time facilitating a further increase in the size of the first air inlet cavity 110, and increasing the volume of the clothing processing cavity 32 defined by the barrel body 30 and the barrel cover 10.

[0066] In some embodiments, the ventilation portion 128 is connected to the peripheral wall 112 in an arc transition to ensure a smooth transition between the ventilation portion 128 and the peripheral wall 112, thereby avoiding a sharp angle between the ventilation portion 128 and the peripheral wall 112 to prevent the angle from hooking clothing in the inner cavity of the barrel 30.

[0067] In some embodiments, the ventilation portion 128 is connected to the middle portion 127 by an arc transition to ensure a smooth transition between the ventilation portion 128 and the middle portion 127, thereby avoiding a sharp angle between the ventilation portion 128 and the middle portion 127 to prevent the angle from hooking clothes in the inner cavity of the barrel 30.

[0068] In some embodiments, the side of the middle portion 127 facing away from the clothing access opening 31 is used to install a rotating shaft 41, and the rotating shaft 41 is used to cooperate with a driving member of the dryer to drive the clothing processing drum assembly 1 to rotate and achieve uniform drying of the clothing.

[0069] In some examples, such as Fig.11 , Fig.12 As shown, one end of the rotating shaft 41 is fixedly connected to the middle part 127 through a fixed bracket 42, and the other end of the rotating shaft 41 is supported on the air duct shell assembly 70 of the dryer through a bearing 43. Thus, the rotating shaft 41 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.

[0070] In other examples, such as Figure 1As shown, the rotating shaft 41 is fixed to the middle part 127, for example, the rotating shaft 41 and the middle part 127 are an integrally formed part, and the other end of the rotating shaft 41 is supported on the air duct shell assembly 70 of the dryer through a bearing 43, thereby, the rotating shaft 41 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.

[0071] In some embodiments of the present invention, Figure 8-Figure 10 As shown, the ventilation hood 13 is perpendicular to the axial direction of the drum body 30, so that multiple ventilation hoods 13 are on the same plane perpendicular to the axial direction of the drum body 30, and multiple ventilation hoods 13 are located in one plane, which is convenient for improving the appearance of the dryer.

[0072] In some embodiments of the present invention, Fig.10 As shown, the side of the drum cover 10 facing the clothing access port 31 has a mounting recess 122, the mounting port 121 is arranged on the bottom wall of the mounting recess 122, and the ventilation hood 13 is arranged in the mounting recess 122, so that the mounting recess 122 can be used to preliminarily define the position of the ventilation hood 13 to facilitate the subsequent fixation of the ventilation hood 13.

[0073] In some embodiments, Figure 1 As shown, the drum cover 10 includes a cover body 12 and a ventilation cover 13, the cover body 12 includes a peripheral wall 112 and an end wall 111, the end wall 111 includes a middle portion 127 and a ventilation portion 128, the ventilation portion 128 is located at the periphery of the middle portion 127 and connects the middle portion 127 and the peripheral wall 112, the ventilation portion 128 is a sheet metal part, and a mounting recess 122 can be formed on one side of the ventilation portion 128 facing the clothing access opening 31 by stamping, and a convex portion 129 is formed on the other side of the ventilation portion 128. Among them, the side wall of the mounting recess 122 extends from the inside to the outside in a direction close to the clothing access opening 31, which is convenient for reducing the difficulty of stamping.

[0074] In some embodiments, Figure 8 , Fig. 9 As shown, the extension direction of the base surface of the inner wall surface of the ventilation portion 128 is perpendicular to the axial direction of the barrel body 30. A mounting recess 122 can be formed on the base surface by stamping the base surface, and a convex portion 129 is formed on the outer wall surface of the ventilation portion 128. After the ventilation hood 13 is installed in the mounting recess 122, the ventilation hood 13 is perpendicular to the axial direction of the barrel body 30.

[0075] In some embodiments of the present invention, Figure 6 , Figure 7As shown, a plurality of fixed flanges 125 are provided at the edge of the hole of the mounting opening 121, and a plurality of fixed posts 25 are provided on the side of the ventilation hood 13 away from the clothing access opening 31. The plurality of fixed posts 25 correspond to the positions of the plurality of fixed flanges 125 one by one, and each fixed post 25 is connected to the corresponding fixed flange 125 by fasteners to fix the ventilation hood 13 at the mounting opening 121.

[0076] In some embodiments of the present invention, Figure 6 , Figure 7 As shown, a positioning hole 126 is provided at the edge of the installation opening 121, and a positioning column 26 is provided on the side of the ventilation hood 13 away from the clothing access opening 31. The positioning column 26 is plugged into the positioning hole 126 to preliminarily limit the position of the ventilation hood 13 at the installation opening 121, thereby facilitating subsequent fixation.

[0077] In some embodiments, Figure 7 As shown, the positioning column 26 includes two limit rods, and the two limit rods have a force moving away from each other, wherein, when the two limit rods are moved toward each other, the overall diameter of the positioning column 26 becomes smaller, and the positioning column 26 can pass through the positioning hole 126 at the edge of the installation opening 121. When the two limit rods are loosened, the two limit rods move in the direction away from each other to stop against the inner wall of the positioning hole 126, thereby realizing the cooperation between the positioning column 26 and the positioning hole 126, and positioning the ventilation hood 13 at the installation opening 121.

[0078] In some embodiments, the positioning column 26 and the second ventilation hole 133 on the ventilation cover 13 are detachably matched, so that it is convenient to adjust the position of the positioning column 26 on the ventilation cover 13.

At this time, the fixed column 25 on the ventilating hood 13 corresponds one by one to the fixed flange 125, and the fixed column 25 and the fixed flange 125 are fixed together by fasteners. At this point, the ventilating hood 13 is fixed at the mounting opening 121.

[0080] In some embodiments of the present invention, Figure 5As shown, there are multiple mounting openings 121 and ventilation hoods 13, and the multiple mounting openings 121 are arranged at intervals in the circumferential direction of the drum cover 10, and the multiple ventilation hoods 13 cover the multiple mounting openings 121 one by one, so as to ensure the uniformity of air intake into the inner cavity of the drum body 30 in its circumferential direction, thereby improving the drying efficiency of the dryer.

[0081] Among them, since the cover body 12 is arranged opposite to the clothing access opening 31, the ventilation hood 13 on the cover body 12 will be exposed from the clothing access opening 31, so that the multiple installation openings 121 are arranged at intervals in the circumferential direction of the drum cover 10, so as to realize the orderly arrangement of the multiple ventilation hoods 13 in the circumferential direction of the drum cover 10, which facilitates to improve the aesthetics of the arrangement of the multiple ventilation hoods 13 on the cover body 12, thereby improving the aesthetics of the dryer.

[0082] In addition, when the laundry treatment drum assembly 1 rotates, the plurality of ventilation covers 13 arranged at intervals in the circumferential direction of the drum cover 10 can form a dynamic visual effect, further improving the aesthetics of the clothes dryer.

[0083] In some optional embodiments of the present invention, Figure 8 As shown, the mounting opening 121 includes a first hole line 1211 and a second hole line 1212.

In this way, when the cover body 12 appears at the clothing access port 31, it can improve the visual effect and improve the beauty of the dryer.

[0086] In some examples, the third hole line 1213 is connected to the first hole line 1211 and the second hole line 1212 by an arc transition.

[0087] In some optional embodiments of the present invention, the ratio of the total ventilation volume of the multiple ventilation hoods 13 to the total ventilation volume of the drum cover 10 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 30, thereby ensuring the drying of the clothes in the middle part of the inner cavity of the drum body 30 and ensuring the drying effect of the center of the dryer.

[0088] Specifically, the total ventilation volume at the ventilation hood 13 is used to ensure air intake to the middle of the barrel 30 and to ensure the central drying effect of the dryer.
