[0039] 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.

[0040] 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.

[0041] like Figure 1-Figure 6 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 .

[0042] The barrel body 30 has an open opening at one axial end and a clothing taking-in and placing opening 31 at the other end. The user can place the clothes that need to be dried into the inner cavity of the barrel body 30 from the clothing taking-in and placing opening 31. The barrel cover 10 closes the open opening and includes a separately formed cover body 12 and a ventilation hood 13. The cover body 12 is provided with a mounting opening 121. The ventilation hood 13 is provided on the cover body 12 and covers the mounting opening 121. The ventilation hood 13 is provided with a plurality of ventilation holes 133 connected with the inner cavity of the barrel body 30. External air can enter the inner cavity of the barrel body 30 through the plurality of ventilation holes 133 on the ventilation hood 13 to dry the clothes in the clothing processing cavity 32.

[0043] The ventilation cover 13 is tilted relative to the axial direction of the barrel 30, so that the size of the ventilation cover 13 is increased, thereby increasing the air intake at the ventilation cover 13, increasing the air intake of the inner cavity of the barrel 30, and improving the drying efficiency of the clothes dryer. External air enters the inner cavity of the barrel 30 through the multiple ventilation holes 133.

[0044] The ventilation holes 133 have 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.

[0045] It can be understood that the number of mounting openings 121 on the cover body 12 is much smaller than the total number of 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 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.

[0046] The utility model forms a plurality of relatively large installation openings 121 on the cover body 12, arranges the ventilation hood 13 at the installation openings 121, and provides a plurality of ventilation holes 133 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 ventilation holes 133 on the ventilation hood 13. Therefore, compared with the solution of directly processing a plurality of small holes on the cover body 12, the present solution has a lower processing difficulty and is convenient for reducing processing costs.

[0047] 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.

[0048] 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.

[0049] In some specific embodiments of the present invention, Figure 1-Figure 6 As shown, the laundry treatment drum assembly 1 includes a drum body 30 and a drum cover 10

[0050] In some embodiments of the utility model, the ventilation hood 13 extends from the inside to the outside along the radial direction of the cover body 12 toward the clothing access port 31, so that the ventilation hood 13 protrudes outward in the direction away from the clothing access port 31. This can avoid the ventilation hood 13 occupying the inner cavity space of the barrel 30, and provide space for the clothes in the barrel 30 to flow out, thereby facilitating increasing the maximum capacity of the dryer and improving the efficiency of the dryer.

[0051] like Figure 1 , Figure 6 As shown, the drum cover 10 is located at the rear end of the drum body 30, and the ventilation hood 13 extends forward from the inside to the outside along the radial direction of the cover body 12 (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). This makes it easy to increase the size of the ventilation hood 13, and then increase the air intake on the ventilation hood 13, thereby improving the drying efficiency of the dryer.

[0052] In some embodiments, the ventilation holes 133 are formed into polygonal holes. For example, the ventilation holes 133 can be formed into triangular holes, quadrilateral holes, hexagonal holes, etc. In this way, while ensuring the air intake, a part of the sound waves can be blocked to achieve noise reduction.

[0053] In some embodiments of the present invention, Figure 8 , Fig. 9 As shown, the inner wall surface of the cover body 12 has a mounting recess 122, the mounting opening 121 is arranged on the bottom wall of the mounting recess 122, and the ventilation hood 13 is arranged in the mounting recess 122. In this way, 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.

[0054] In some optional embodiments of the present invention, Figure 5As shown, a portion of the wall of the cover body 12 is recessed toward the outside of the cover body 12 to form a mounting recess 122 on the inner wall surface of the cover body 12, and a protrusion 129 is formed on the outer wall surface of the cover body 12 to reserve space for the arrangement of the vent hood 13. In this way, when the vent hood 13 is installed in the mounting recess 122, it can be avoided that the vent hood 13 protrudes out of the wall of the cover body 12 toward the clothing access port 31, and the clothing in the inner cavity of the barrel 30 is prevented from being hooked by the vent hood 13.

[0055] It can be understood here that the wall of the cover body 12 facing the clothing access opening 31 is the inner wall surface, and the wall of the cover body 12 facing away from the clothing access opening 31 is the outer wall surface.

[0056] In some embodiments, the cover body 12 is a sheet metal part, and a mounting recess 122 can be formed on the inner wall surface of the cover body 12 by stamping, and a convex portion 129 can be formed on the outer wall surface of the cover body 12. 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 makes it easy to reduce the difficulty of stamping and facilitates the manufacture of stamping molds.

[0057] In some embodiments, Figure 6 As shown, the base surface of the inner wall surface of the cover body 12 extends from the inside to the outside toward the direction close to the clothing access port 31, and 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 cover body 12. After the ventilation hood 13 is installed in the mounting recess 122, the ventilation hood 13 extends obliquely from the inside to the outside toward the direction close to the clothing access port 31.

[0058] In some embodiments of the present invention, Figure 3 , Figure 4 As 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.

[0059] In some embodiments of the present invention, Figure 3 , Figure 4 As shown, there is a positioning hole 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 to preliminarily limit the position of the ventilation hood 13 at the installation opening 121, thereby facilitating subsequent fixation.

[0060] In some embodiments, Figure 4As 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 at the edge of the installation port 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, thereby realizing the cooperation between the positioning column 26 and the positioning hole, and positioning the ventilation hood 13 at the installation port 121.

[0061] In some embodiments, the positioning column 26 and the 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.

[0062] like Figure 4 As shown, in the present embodiment, the edge of the hole of the mounting opening 121 is provided with two positioning holes and six fixed flanges 125, the six fixed flanges 125 are arranged at intervals along the circumference of the mounting opening 121, and two positioning holes are arranged on both sides of one of the fixed flanges 125. When the ventilating hood 13 is fixed at the mounting opening 121, the positioning column 26 can be first fixed at the specified position of the ventilating hood 13, and then the positioning column 26 can be passed through the positioning hole from front to back. At this time, the fixing column 25 on the ventilating hood 13 corresponds to the fixed flange 125 one by one, and the fixing 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, which is convenient for ensuring the uniformity of the air intake of the inner cavity of the barrel 30 in its circumferential direction, and is convenient for improving the drying efficiency of the dryer.

[0063] 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.

[0064] 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.

[0065] In some embodiments of the present invention, there are multiple installation openings 121 and ventilation hoods 13 , the multiple installation openings 121 are arranged at intervals in the circumferential direction of the cover body 12 , and the multiple ventilation hoods 13 cover the multiple installation openings 121 one by one.

[0066] In some optional embodiments of the present invention, Figure 7As shown, the mounting opening 121 includes a first hole line 1211 and a second hole line 1212. The first hole line 1211 is closer to the center of the cover body 12 than the second hole line 1212. The first hole line 1211 and the second hole line 1212 are both arc lines. The first hole lines 1211 of multiple mounting openings 121 are arc lines of different segments of the first circle, and the second hole lines 1212 of multiple mounting openings 121 are arc lines of different segments of the second circle. The centers of the first circle and the second circle are both located at the center of the drum cover 10. This makes it easy to arrange the multiple mounting openings 121 harmoniously on the cover body 12, thereby improving the aesthetics of the dryer.

[0067] In some specific embodiments of the utility model, the installation opening 121 also includes two third hole lines 1213, the two ends of the two third hole lines 1213 are respectively connected to the first hole line 1211 and the second hole line 1212, and the third hole line 1213 is one or more combinations of a straight line, an arc line, and a broken line.

[0068] like Figure 7 As shown, in the present embodiment, the third hole line 1213 is a straight line, and the two ends of the third hole line 1213 are respectively connected to the first hole line 1211 and the second hole line 1212 to form a petal-like installation opening 121. Similarly, in order to adapt to the shape of the installation opening 121, the ventilation shape is also a petal-like shape. In this way, when the cover body 12 appears at the clothing access port 31, it can improve the visual effect and the appearance of the dryer.

[0069] In some examples, the third hole line 1213 is connected to the first hole line 1211 and the second hole line 121 by an arc transition.

[0070] In some embodiments of the present invention, the cover body 12 is an integrally formed metal part, which is easy to form and has high structural strength. The mounting opening 121 can be formed by stamping the cover body 12, which is convenient to process and has high processing efficiency.

[0071] In some embodiments of the present invention, the ventilation hood 13 is a metal part or a plastic part. The ventilation hood 13 made of metal has higher structural strength and better appearance uniformity with the cover body 12, while the ventilation hood 13 made of plastic is lighter and has lower cost.

[0072] In some embodiments of the present invention, Figure 3 , Figure 8As shown, the drum cover 10 has a first extension portion 11 extending in a direction away from the clothing access port 31, and the first extension portion 11 defines a first air inlet chamber 110 connected to the inner cavity of the drum body 30. The first air inlet chamber 110 is connected to the ventilation hole 133 and the inner cavity of the drum body 30. By extending the first extension portion 11 in a direction away from the clothing access port 31, the first air inlet chamber 110 is connected to the inner cavity of the drum body 30, so that the volume of the clothing processing chamber 32 defined by the drum body 30 and the drum cover 10 is increased, thereby facilitating the improvement of 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 clothing in the clothing processing chamber 32 and the air is increased, thereby facilitating the improvement of the efficiency of the clothing drying process.

[0073] In some optional embodiments of the present invention, Figure 3 As shown, the first extension portion 11 includes a first installation wall 113 arranged opposite to the clothing access opening 31, and the first installation wall 113 extends from the inside to the outside along the radial direction of the drum cover 10 toward the clothing access opening 31, and the installation opening 121 is arranged on the first installation wall 113, so that the first installation wall 113 extends from the inside to the outside along the radial direction of the drum cover 10 toward the clothing access opening 31, which is convenient for increasing the volume of the first air inlet chamber 110, thereby facilitating the improvement of the maximum drying capacity of the dryer, and at the same time, by increasing the volume of the clothing processing chamber 32, it is convenient to increase the clothing processing chamber 32.

[0074] In addition, the first installation wall 113 extends from the inside to the outside along the radial direction of the drum cover 10 toward the clothing access opening 31, which makes it easier to design the size of the installation opening 121 larger, thereby facilitating increasing the air intake volume of the first air inlet chamber 110.

[0075] In some embodiments, Fig.11 As shown, the dryer includes an air duct shell assembly 70, which defines a ventilation cavity 71 with an opening on one side, a drum cover 10 covers the opening and a first extension portion 11 extends from the opening into the ventilation cavity 71, a plurality of ventilation holes 133 connect the first air inlet cavity 110 and the ventilation cavity 71, and the air in the ventilation cavity 71 enters the inner cavity of the drum body 30 through the opening from the plurality of first ventilation holes 133 and the plurality of second ventilation holes 133 to dry the clothes in the inner cavity of the drum body 30.

[0076] Among them, the drum cover 10 and the drum body 30 define a clothing processing chamber 32, so that the first extension portion 11 extends from the opening into the ventilation chamber 71. The capacity of the clothing processing chamber 32 is no longer limited by the space limitation behind the air duct shell assembly 70, thereby increasing the capacity of the clothing processing chamber 32.

[0077] In some specific embodiments of the present invention, Figure 3As shown, the first extension portion 11 also includes a second mounting wall 114, which is used to mount the rotating shaft 41. The second mounting wall 114 is arranged opposite to the clothing access port 31 and the first mounting wall 113 surrounds the outer periphery of the second mounting wall 114. The rotating shaft 41 is used to cooperate with the driving member of the dryer to drive the clothing processing drum assembly 1 to rotate, thereby achieving uniform drying of the clothing.

[0078] like Fig.11 , Fig.12 As shown, one end of the rotating shaft 41 is fixedly connected to the second mounting wall 114 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, 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.

[0079] In other embodiments, the rotating shaft 41 is fixed to the second mounting wall 114. For example, the rotating shaft 41 and the second mounting wall 114 are integrally formed. 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.

[0080] In some specific embodiments of the present invention, Figure 5 As shown, the drum cover 10 also has a second extension portion 14 extending in a direction away from the clothing access port 31, the second extension portion 14 is located between the first extension portion 11 and the drum body 30, and the first extension portion 11 extends in a direction away from the clothing access port 31 relative to the second extension portion 14, wherein the second extension portion 14 defines a second air inlet chamber 140, and the second air inlet chamber 140 is connected between the first air inlet chamber 110 and the inner cavity of the drum body 30, and a clothing processing chamber 32 is defined between the drum cover 10 and the drum body 30. By providing the second extension portion 14, the volume of the clothing processing chamber 32 can be increased, thereby facilitating an increase in the maximum drying capacity of the dryer, and at the same time, by increasing the volume of the clothing processing chamber 32, it is convenient to increase the contact area between the clothing in the clothing processing chamber 32 and the air, thereby facilitating an improvement in the efficiency of drying the clothing.

[0081] In some embodiments, the cover body 12 includes a second extension portion 14, a first mounting wall 113 and a second mounting wall 114, wherein from the outside to the inside are the second extension portion 14, the first mounting wall 113 and the second mounting wall 114, respectively. The second extension portion 14, the first mounting wall 113 and the second mounting wall 114 are integrally formed metal parts, which makes it easy to reduce the connection structure between the second extension portion 14 and the first mounting wall 113, and reduce the connection structure between the first mounting wall 113 and the second mounting wall 114, which is beneficial to improve the connection reliability between the second extension portion 14 and the first mounting wall 113, and the first mounting wall 113 and the second mounting wall 114, and is beneficial to improve production efficiency.
