Description

Technical Field

[0001] This utility model relates to a clothes dryer, and more specifically, to a drum dryer. Background Technology

[0002] While tumble dryers offer convenience in modern life, people are increasingly valuing their aesthetics. However, the main body, front panel, and back panel of current mainstream products are generally made of sheet metal. Although sheet metal is strong, it is not aesthetically pleasing, and changing its shape requires significant costs. Therefore, cheaper and more malleable plastic is used as a substitute, allowing for more diverse appearances. However, in actual production, it has been found that plastic parts have limited strength and are prone to creep, resulting in insufficient rigidity at joints. The body, front panel, and back panel are easily deformed, cracked, and even have screw holes break. Furthermore, the rotating drum during drying, while maximizing drying efficiency at low speeds, still generates considerable centrifugal force. The weak plastic body structure cannot effectively suppress and absorb this vibration energy, causing the entire machine to shake or even shift during operation. Long-term vibration can accelerate structural fatigue, shorten the machine's lifespan, and pose safety hazards. Therefore, a tumble dryer is needed that strengthens the connection between the body, front panel, and back panel, preventing body twisting.

[0003] For the reasons mentioned above, how to strengthen the connection between the front panel, the housing, and the rear panel is the problem addressed in this application. Utility Model Content

[0004] To address the shortcomings of existing technologies, a tumble dryer is provided. This device can strengthen the connection between the front panel, the cabinet, and the rear panel, preventing the cabinet from twisting.

[0005] To achieve the above objectives, the following technical solution is provided: a drum dryer, characterized in that it includes a housing, a front panel, a fixed plate assembly, a rear panel, and a connecting bracket assembly. The fixed plate assembly is connected inside the front panel and is used to increase the contact area with the front panel. The housing is connected to the fixed plate assembly, and the fixed plate assembly is used to increase the contact area with the front panel. The connecting bracket assembly is connected inside the housing and is used to increase the contact area with the housing. The rear panel is connected to the connecting bracket assembly, and the connecting bracket assembly is used to increase the contact area with the rear panel.

[0006] Furthermore, the fixing plate assembly includes a boss and an additional plate. The boss is fixedly connected to the housing, and the additional plate is fixedly connected to the boss. The boss abuts against the inner wall of the front plate.

[0007] Furthermore, multiple first connecting posts are fixedly connected to the front panel, each first connecting post having a first connecting hole. Multiple second connecting holes are provided on the mounting plate, each second connecting hole corresponding to a first connecting hole. A protective plate is fixedly connected to each first connecting post.

[0008] Furthermore, the fixed plate assembly also includes a support plate, which is fixedly connected to the boss and is used to support the front plate.

[0009] Furthermore, the fixing plate assembly also includes positioning posts, and the front plate is provided with positioning holes. The positioning posts are fixedly connected to the support plate, and the positioning holes are used to accommodate the positioning posts.

[0010] Furthermore, the connecting bracket assembly includes an upper connecting bracket and a side connecting bracket, which are detachably connected. Both the upper connecting bracket and the side connecting bracket abut against the inner wall of the housing, and both the upper connecting bracket and the side connecting bracket are fixedly connected to the rear plate.

[0011] Furthermore, both the upper connecting frame and the side connecting frame are provided with multiple second connecting posts, and the rear plate is provided with multiple third connecting holes, which are set corresponding to the second connecting posts.

[0012] Furthermore, the housing is fixedly connected with multiple connecting seats, and the upper connecting frame and the side connecting frame are each provided with multiple connecting slots. The connecting slots are used to accommodate the connecting seats, and the connecting seats are also provided with a fourth connecting hole.

[0013] Furthermore, both ends of the upper connecting frame are provided with fitting grooves, and the side connecting frame is provided with fitting parts. The fitting grooves are used to accommodate the fitting parts.

[0014] Furthermore, the upper connecting frame and the side connecting frame form a U-shape after being connected.

[0015] In summary, the above technical solution has the following beneficial effects: On the one hand, this utility model uses a connecting bracket assembly with a specific width and thickness as an intermediate connector. Its width is mainly used to increase the contact area with the rear plate and provide a wide support surface, while its thickness is mainly used to increase the contact area with the inner surface of the box and provide a deep joint surface.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] Reference Figure 1-7 As shown, a tumble dryer includes a housing 1, a front panel 2, a fixed plate assembly 3, a rear panel 4, and a connecting bracket assembly 5. The fixed plate assembly 3 is connected inside the front panel 2 and is used to increase the contact area with the front panel 2. The housing 1 is connected to the fixed plate assembly 3, and the fixed plate assembly 3 is used to increase the contact area with the front panel 2. The connecting bracket assembly 5 is connected inside the housing 1 and is used to increase the contact area with the housing 1. The rear panel 4 is connected to the connecting bracket assembly 5, and the connecting bracket assembly 5 is used to increase the contact area with the rear panel 4.

[0020] The fixing plate assembly 3 is installed on the inside of the front plate 2. The fixing plate assembly 3 is usually an integral structure extending from the front end of the box 1. It is connected to the front plate 2 by bolts or screws. Therefore, the fixing plate assembly 3 can increase the contact area between the box 1 and the front plate 2 as a connection medium. The fixing plate assembly 3 is actually used as a more robust mounting base inside the front plate 2. The bolts or screws no longer just connect the thin edges of the box 1 and the front plate 2, but pass through the extended fixing plate from the box 1 and are tightened to the main body of the front plate 2. In this way, the fastening force applied by the bolts or screws can act between the two large-area plates. When the box 1 is subjected to vibration or external force, these forces are no longer concentrated around a few small screw holes. The larger contact area allows the force to be effectively distributed throughout the fixing plate assembly 3 and the interior of the front plate 2. The connecting bracket assembly 5 is a rigid component with a certain width and thickness. The connecting bracket assembly 5 is connected and fixed to the inner surface of the housing 1, and the rear plate 4 is connected and fixed to the connecting bracket assembly 5. The connecting bracket assembly 5 has a large width, which significantly increases the actual contact area between the fixing frame and the rear plate 4. The connecting bracket assembly 5 has a large thickness, which significantly increases the actual contact area between the fixing frame and the inner surface of the housing 1. Through this connecting bracket assembly 5, the rear plate 4 is indirectly connected to the housing 1 through a connection point with a greatly increased contact area. When the dryer is running, the rotating drum will generate significant vibrations. The increased contact area and more stable connection can more effectively absorb and dampen these vibrations. The forces transmitted between the housing 1 and the back panel 4, as well as between the housing 1 and the front panel 2, are distributed to a larger surface area, avoiding stress concentration on a few points or a small area. When bolts or other fasteners are tightened, the larger contact area generates greater friction, resisting relative sliding or loosening between components, preventing excessive transmission of vibration energy to other parts of the housing 1 or the back panel 4, reducing abnormal noises and shaking, reducing relative displacement or deformation of components under stress, and improving the overall rigidity of the equipment. This strengthens the connection between the front panel 2, the housing 1, and the back panel 4, preventing the housing 1 from twisting. In addition, the housing 1 and the fixing plate assembly 3 can adopt an integrated structure, which facilitates overall installation and control of subsequent processing technology; This utility model utilizes a connecting bracket assembly 5 with a specific width and thickness as an intermediate connector. Its width is mainly used to increase the contact area with the rear plate 4, providing a wide support surface, and its thickness is mainly used to increase the contact area with the inner surface of the housing 1, providing a deep joint surface. On the other hand, by establishing a large-area rigid connection interface in the built-in fixing plate assembly 3 and fastening it with bolts or screws, the connection tightness, structural stability, vibration resistance and overall structural strength are enhanced by maximizing the contact area.

[0021] Furthermore, the fixing plate assembly 3 includes a boss 31 and an mounting plate 32. The boss 31 is fixedly connected to the housing 1, and the mounting plate 32 is fixedly connected to the boss 31. The boss 31 abuts against the inner wall of the front plate 2.

[0022] The boss 31 is directly fixed to the housing 1. Its core function is to extend forward so that its outer end face abuts against the inner wall of the front panel 2. During assembly, the boss 31 abuts against the inner wall of the front panel 2 to help accurately determine the position of the front panel 2 relative to the housing 1. At the same time, it provides a direct rigid support point for the front panel 2. The force acting on the housing 1 is directly transmitted to the front panel 2 through the boss 31. The mounting plate 32 is fixedly connected to the boss 31 and covers a larger area inside the front plate 2. This can further increase the contact area with the inner surface of the front plate 2 and distribute the force transmitted from the boss 31 and its own supporting force to a larger area of ​​the front plate 2. In addition, the outer corners of the boss 31 and the mounting plate 32 are designed to be rounded, which can eliminate stress concentration, improve structural strength and fatigue life, and prevent cracking.

[0023] Furthermore, a plurality of first connecting posts 21 are fixedly connected to the front plate 2, and the first connecting posts 21 are provided with first connecting holes 22. The mounting plate 32 is provided with a plurality of second connecting holes 33, and the second connecting holes 33 are provided corresponding to the first connecting holes 22. The first connecting posts 21 are fixedly connected to a protective plate 23.

[0024] A first connecting post 21 is provided on the front panel 2. The first connecting hole 22 on the first connecting post 21 can be matched with the second connecting hole 33 on the mounting plate 32. The mounting plate 32 can be fixed to the front panel 2 using bolts or screws. Compared with the method of fixing the housing 1 directly to the thin plate of the front panel 2, the first connecting post 21 provides a more robust and reliable connection point than drilling holes directly on the thin plate of the front panel 2. This avoids the problems of insufficient strength, easy deformation or tearing that may be caused by drilling holes directly on the thin-walled front panel 2. In addition, a protective plate 23 is provided on these connection points to prevent the parts from directly damaging the first connecting post 21 during vibration, further enhancing the strength of the overall structure. It can also be used to guide the installation of the housing 1.

[0025] Furthermore, the fixed plate assembly 3 also includes a support plate 34, which is fixedly connected to the boss 31 and is used to support the front plate 2.

[0026] Furthermore, the fixing plate assembly 3 also includes a positioning post 35. The front plate 2 is provided with a positioning hole 36. The positioning post 35 is fixedly connected to the support plate 34, and the positioning hole 36 is used to accommodate the positioning post 35.

[0027] The support plate 34 is fixedly connected to the boss 31 and can support the front plate 2, preventing the front plate 2 from sagging due to its own weight or external force. The positioning post 35 is fixedly connected to the support plate 34 and, together with the positioning hole 36 on the front plate 2, guides the installation of the front plate 2. It can also serve as a reinforcing connection structure.

[0028] Furthermore, the connecting bracket assembly 5 includes an upper connecting bracket 51 and a side connecting bracket 52. The upper connecting bracket 51 and the side connecting bracket 52 are detachably connected. Both the upper connecting bracket 51 and the side connecting bracket 52 abut against the inner wall of the housing 1, and both the upper connecting bracket 51 and the side connecting bracket 52 are fixedly connected to the rear plate 4.

[0029] The connecting bracket assembly 5 consists of an upper connecting frame 51 and a side connecting frame 52, which are detachably connected together to form a more flexible and easier-to-install support frame. This frame is also tightly abutted against the inner wall of the housing 1, which significantly increases the contact area between the entire connecting bracket assembly 5 and the inner surface of the housing 1, thereby transmitting the support force provided by the housing 1 more evenly to the entire frame and facilitating maintenance and replacement.

[0030] Furthermore, both the upper connecting frame 51 and the side connecting frame 52 are provided with multiple second connecting posts 53, and the rear plate 4 is provided with multiple third connecting holes 41, which are set corresponding to the second connecting posts 53.

[0031] Multiple second connecting posts 53 are provided on the transverse and side connecting brackets 52, and third connecting holes 41 are provided on the corresponding positions on the rear plate 4. During assembly, the connecting holes on the rear plate 4 are aligned with the second connecting posts 53 on the fixing bracket, and then connecting parts such as bolts or nails can be used for connection. This multi-point fixing method greatly increases the number of contact points and connection strength between the rear plate 4 and the connecting bracket assembly 5, making the force on the rear plate 4 more uniform and less prone to deformation or loosening.

[0032] Furthermore, the housing 1 is fixedly connected with multiple connecting seats 11, and the upper connecting frame 51 and the side connecting frame 52 are each provided with multiple connecting slots 54. The connecting slots 54 are used to accommodate the connecting seats 11, and the connecting seats 11 are also provided with a fourth connecting hole 12.

[0033] Multiple connecting seats 11 are pre-fixed on the inner wall of the housing 1. Corresponding connecting grooves 54 are designed on the transverse and side connecting frames 52. During assembly, the connecting grooves 54 on the connecting bracket assembly 5 fit into or lock the connecting seats 11 on the housing 1. The cooperation between the connecting grooves 54 and the connecting seats 11 enables the connecting bracket assembly 5 to be precisely aligned and initially fixed with the housing 1 at multiple positions. This not only increases the connection area between the fixing frame and the housing 1, but more importantly, it provides strong resistance to shear and torsion, preventing the fixing frame from shifting or rotating relative to the housing 1. In addition, the triangular prism-shaped connecting seat 11 provides a stable anchor point on the inner wall of the housing 1, which can effectively prevent rotation and ensure precise alignment. The fourth connecting hole 12 on the connecting seat 11 is used to finally screw in bolts or screws to lock the upper connecting frame 51 and the side connecting frame 52 onto the connecting seat 11, thereby completing an extremely strong and reliable connection between the fixing frame and the housing 1.

[0034] Furthermore, both ends of the upper connecting frame 51 are provided with fitting grooves 55, and the side connecting frame 52 is provided with fitting parts 56. The fitting grooves 55 are used to accommodate the fitting parts 56.

[0035] Furthermore, the upper connecting frame 51 and the side connecting frame 52 form a U-shape after being connected.

[0036] The fitting 56 of the side connecting frame 52 is inserted into the fitting groove 55 at both ends of the upper connecting frame 51. If necessary, the strength of the fitting structure can be further strengthened by bolts or screws, which can form a physical interlock, simplify the assembly process, resist lateral shear force, and counteract displacement caused by vibration. The arc shape at both ends of the upper connecting frame 51 can match the common inner wall curved surface contour of the box 1, and can also increase the contact area. The arc shape of the L-shaped corner node can eliminate right angle stress concentration points, disperse vibration load, and prevent metal fatigue fracture. In addition, the mold structure of the independent upper connecting frame 51 and side connecting frame 52 is simpler during molding, and the mold cost and structure are more advantageous. The controllability and stability of the process are stronger than the one-piece molding process.
