[0031] In order to more clearly understand the above-mentioned purposes, technical solutions and advantages of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application, and detailed understanding of how to solve the problems raised in the above-mentioned background art.

[0032] It should be noted that the drum is the core component of the dryer, usually welded from high-quality medium carbon steel plates. It is the main place for drying clothes. The drum is installed on the frame, which has a circular opening for putting in or taking out clothes. Therefore, the air inlet of the exhaust pipe can be set along the edge of the frame. At the same time, a door is provided corresponding to the circular opening. The door can be installed on the door frame, and the door frame and the frame are fixedly connected, so that the exhaust pipe, drum and door can be installed in an integrated manner.

[0033] like Figures 1 to 5 As shown, a dryer exhaust pipe includes: a pipe body 1, installed on the opening frame of the cylinder, the pipe body 1 having a connected air inlet 11 and an air outlet 12; a first filter element 2, detachably installed on the air inlet 11, the first filter element 2 being used to filter fine fibrous debris; and a second filter element 3, detachably installed on the door, the second filter element 3 covering the first filter element 2, the second filter element 3 being used to intercept large particulate debris.

[0034] The above solution forms a dual filtration system by stacking the second filter element 3 and the first filter element 2, significantly reducing the risk of clogging the exhaust pipe. Simultaneously, an arc-shaped mounting groove can be provided at the door for installing the second filter element 3. Since the door can be opened or closed, in practical applications, the door is closed during clothes drying, with the second filter element 3 covering the first filter element 2. After drying, the door needs to be opened to remove the clothes, at which point the second filter element 3 moves away from the first filter element 2 as the door opens. This allows users to directly observe both the first and second filters each time they use the dryer. If there are scraps of paper, hair, buttons, or other debris, users can clean or replace them as needed, facilitating preventative maintenance and normal operation of the dryer.

[0035] In this embodiment, the exhaust pipe has a cavity inside, and both the air inlet 11 and the air outlet 12 are connected to the cavity. The exhaust pipe can be formed by blow molding and cutting of high-temperature resistant plastic sheet, which has the advantages of low cost, good sealing performance and high production efficiency. The air inlet 11 is connected to the inner cavity of the cylinder, and the air outlet 12 is connected to the fan. The fan can provide power so that the water vapor generated in the drying process inside the cylinder can be smoothly discharged to the outside of the dryer, ensuring good ventilation and drying efficiency inside the dryer. Furthermore, the first filter element 2 and the second filter element 3 are set at the air inlet 11, which, compared with the traditional filter component installation position, can avoid blockage of the air inlet 11 or the pipe between the air inlet 11 and the filter component.

[0036] like Figure 2 and Figure 3As shown, in one specific embodiment of the improvement, the end of the tube 1 near the air inlet 11 is an arc segment 13, and the end of the tube 1 near the air outlet 12 is a cylindrical segment 14. Specifically, including but not limited to, one side of the arc segment 13 is an arc-shaped surface, so that after the tube 1 is fixed, the arc segment 13 can be designed along the arc of the cylinder as much as possible, increasing the area of ​​the air inlet 11 and increasing the air intake. At the same time, the cylindrical segment 14, after being connected to the fan, can ensure the air outlet, thereby enhancing the air flow and preventing the tube 1 from obstructing the clothes when the cylinder rotates. In addition, the cover-type filter layout design allows the hot air to flow in a laminar flow, reducing wind resistance and improving drying efficiency while ensuring the filtration effect.

[0037] like Figure 2 As shown, in one specific embodiment of the improvement, a plurality of first fixing posts 15 are provided on the side of the tube 1 between the arc segment 13 and the cylindrical segment 14. Specifically, including but not limited to, there is a transition section between the arc segment 13 and the cylindrical segment 14. This transition section has an arc-shaped structure, making the cavity inside the tube 1 for gas flow an arc-shaped flow channel. Simultaneously, the first fixing posts 15 are located on the inner side of the tube 1, below the arc segment 13. Three of the first fixing posts 15 are screw posts, arranged along the arc segment 13. Correspondingly, screw holes 17 are also provided on the frame. The tube 1 can then be fixed to the frame with screws, thereby achieving quick assembly and disassembly of the tube 1.

[0038] like Figure 3 As shown, in one specific embodiment of the improvement, a plurality of reinforcing columns 16 are provided inside the tube 1 between the arc segment 13 and the cylindrical segment 14. Specifically, including but not limited to, there are two reinforcing columns 16, both of which are cylindrical. The reinforcing columns 16 are arranged in the inner cavity of the arc segment 13, and can play a connecting and supporting role between the two inner walls of the arc segment 13, thereby strengthening the overall structural strength of the tube 1, preventing deformation of the arc segment 13 during the high-temperature drying process of clothes, and ensuring the service life of the tube 1.

[0039] like Figure 4As shown, in one specific embodiment of the improvement, the first filter element 2 includes a washable filter screen 21 and a frame 22 surrounding the outer edge of the filter screen 21. The frame 22 is snapped into the tube body 1. Specifically, including but not limited to, both the filter screen 21 and the frame 22 can be injection molded from high-temperature resistant plastic material, and the frame 22 has a mounting groove in the center, in which the filter screen 21 can be installed, so that the frame 22 and the filter screen 21 are integrally injection molded. The frame 22 extends outward relative to the filter screen 21 to form an extension section, which is conducive to the disassembly and assembly of the first filter element 2. The filter screen 21 is embedded in the arc section 13 from the air inlet 11, and the frame 22 covers the air inlet 11, thereby ensuring the airtightness between the tube body 1 and the frame 22. The filter screen 21 has multiple filter holes with a diameter of 0.2-1.5mm, thereby capturing fine fibers such as cotton wool, hair, and dust.

[0040] like Figure 3 and Figure 4 As shown, in one specific embodiment of the improvement, a through hole 221 is provided at one end of the frame 22, and a screw hole 17 is provided at one end of the tube 1. The through hole 221 and the screw hole 17 are vertically aligned. Specifically, including but not limited to, the through hole 221 is located at the right end of the frame 22, and similarly, the screw hole 17 is located on the right side of the air inlet 11. The first filter element 2 and the tube 1 can be fixed by screws, realizing quick disassembly and assembly of the first filter element 2, which is convenient for later cleaning and maintenance.

[0041] like Figure 3 and Figure 4 As shown, in one specific embodiment of the improvement, a clamping section 222 is provided at the other end of the frame 22. The clamping section 222 is inserted into the air inlet 11 and fits against the inner wall of the tube 1. Specifically, including but not limited to, the clamping section 222 is located at the left end of the frame 22, and the clamping section 222 and the bottom surface of the frame 22 are on the same straight line. Based on this, when actually disassembling and assembling the first filter element 2, the clamping section 222 can be inserted into the air inlet 11 first, and the upper wall surface of the clamping section 222 fits against the inner wall of the frame 22. At this time, the frame 22 can be initially positioned, and then it can be installed in the through hole 221 and screw hole 17 by screws, thereby completing the installation of the first filter element 2. When disassembling, it is only necessary to remove the screws and directly remove the first filter element 2 from the air inlet 11, thereby completing the disassembly of the first filter element 2, which is beneficial for the later cleaning and maintenance of the first filter element 2.

[0042] like Figure 5As shown, in one specific embodiment of the improvement, the second filter element 3 is an arc-shaped plastic filter screen. Specifically, including but not limited to, the structure of the second filter element 3 corresponds vertically to the structure of the frame 22, both being arc-shaped structures. In this case, the second filter element 3 can completely cover the frame 22, but there is a gap between the second filter element 3 and the frame 22 to ensure that the second filter element 3 can move relative to the first filter element 2, that is, the second filter element 3 moves with the door, avoiding friction damage between the two. The second filter element 3 can be injection molded from high-temperature resistant plastic material, and has multiple filter holes with a diameter of 2-5mm, thereby intercepting large particles of debris, such as buttons, coins, and fibrous clumps.

[0043] like Figure 5 As shown, in one specific embodiment of the improvement, the second filter element 3 is provided with multiple second fixing posts 31. Specifically, including but not limited to, there are four second fixing posts 31, all of which are screw posts. The four second fixing posts 31 are set on the inner extension plate of the second filter element 3, and the inner edge of the second filter element 3 is provided with an extension section. When the second filter element 3 is installed, the extension section can be embedded into the mounting groove of the door body. At this time, the extension section on the inner side of the second filter element 3 can cover the mounting groove, which can ensure the sealing between the second filter element 3 and the door body. Then, the second filter element 3 is fixed to the door body with screws, thereby realizing the quick installation and removal of the second filter element 3, which is beneficial for subsequent cleaning and maintenance.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
