Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an exhaust assembly and a portable air conditioner. Background Technology

[0002] Currently, the exhaust ducts of household portable air conditioners generally use spiral telescopic exhaust ducts. The exhaust port of the air conditioning duct is fixedly connected to the spiral telescopic exhaust duct through a connector to realize the assembly of the exhaust component of the portable air conditioner.

[0003] The existing portable air conditioner exhaust components require the threaded connector to be installed at the air outlet of the duct first by snapping or screwing, and then the spiral telescopic exhaust pipe is screwed onto the threaded connector to complete the assembly of the exhaust components. The process is cumbersome and the assembly efficiency is low.

[0004] In summary, overcoming the aforementioned deficiencies of existing portable air conditioner exhaust components is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an exhaust assembly and a portable air conditioner to alleviate the technical problems of cumbersome assembly process and low efficiency of the exhaust assembly of portable air conditioners in the prior art.

[0006] The exhaust assembly provided by the present invention includes an air duct and an exhaust pipe.

[0007] The exhaust pipe is inserted into the air duct. The exhaust pipe has threads, and the side wall of the air duct is provided with an elastic buckle that can be engaged into the threaded recess on the exhaust pipe.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] The exhaust assembly provided by this invention involves aligning the exhaust pipe opening with the air outlet of the duct and forcefully inserting the exhaust pipe into the duct. During this process, the elastic clips on the side wall of the duct undergo a certain elastic deformation under the action of external force, allowing the elastic clips to pass over the threaded protrusions on the exhaust pipe. After each threaded protrusion, the elastic clips return to their original shape and engage with the threaded recesses. After the external force is removed, the elastic clips remain in the threaded recesses they are currently in, blocked by the threaded protrusions on the exhaust pipe. This achieves the engagement of the elastic clips with the threaded recesses, completing the assembly of the exhaust pipe and the duct.

[0010] Therefore, the exhaust assembly provided by the present invention directly connects the exhaust pipe and the air duct, eliminating the need for a joint between them. This not only reduces the number of parts and simplifies the assembly process, but also allows for easy assembly by simply inserting the exhaust pipe into the air duct. Compared to screwing, this method is easier to operate and has higher assembly efficiency.

[0011] Preferably, as one possible implementation, the exhaust pipe is inserted into the air outlet of the air duct, and the elastic buckle protrudes towards the inside of the air duct.

[0015] Preferably, as one possible implementation, the top surface of the elastic buckle facing the outside of the air duct is a guide surface, and the guide surface is inclined from the outside to the inside towards the central axis of the air outlet along the axial direction of the air outlet.

[0016] The benefits are that assembly is less strenuous and the damage to the structure caused by compressive stress is reduced.

[0017] Preferably, as one possible implementation, the bottom surface of the elastic buckle facing the inside of the air duct is a limiting surface, and the limiting surface is inclined from the inside to the outside towards the central axis of the air outlet along the axial direction of the air outlet, and the angle between the limiting surface and the central axis of the air outlet is in the range of 80-90°.

[0018] The beneficial effect is that it can ensure the secure assembly of the exhaust pipe and the air duct.

[0020] And / or, the angle between the guide surface and the central axis of the air outlet is in the range of 50 to 80°.

[0021] The beneficial effect is that the exhaust pipe can be smoothly inserted into the air outlet of the air duct.

[0022] Preferably, as one possible implementation, the elastic buckle has two end faces, which are respectively located at both ends of the elastic buckle along the circumference of the air outlet, and at least one of the end faces has a chamfer or rounded corner on the side facing the central axis of the air outlet.

[0023] The advantage is that the exhaust pipe can be removed by screwing on the thread, and it can also prevent the exhaust pipe from being scratched by sharp corners.

[0024] Preferably, as one possible implementation, there are at least two elastic buckles, and the elastic buckles are arranged at intervals along the circumference of the air outlet of the air duct.

[0025] The beneficial effect is that it can improve the assembly reliability and stress balance of the exhaust pipe, and the exhaust pipe is not easy to come off.

[0029] The beneficial effect is that it can improve the stability of the exhaust pipe assembly, making the exhaust pipe less prone to shaking.

[0030] Preferably, as one possible implementation, the exhaust pipe is a spiral telescopic pipe.

[0031] The beneficial effect is that,

[0032] Preferably, as one possible implementation, the protective net is integrally formed with at least a portion of the air duct.

[0046] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0049] See Figures 1-4This embodiment provides an exhaust assembly, which includes an air duct 100 and an exhaust pipe 200; the exhaust pipe 200 is inserted into the air duct 100, the exhaust pipe 200 has threads, and an elastic buckle 300 is provided on the side wall of the air duct 100, the elastic buckle 300 can be snapped into the threaded recess 220 on the exhaust pipe 200.

[0050] In this embodiment, the exhaust assembly is assembled by aligning the outlet of the exhaust pipe 200 with the outlet 110 of the duct 100 and forcefully inserting the exhaust pipe 200 into the duct 100. During this process, the elastic clips 300 on the side wall of the duct 100 undergo a certain elastic deformation under the action of external force, allowing the elastic clips 300 to pass over the threaded protrusions 210 on the exhaust pipe 200. After each threaded protrusion 210, the elastic clips 300 return to their original shape and engage with the threaded recesses 220. After the external force is removed, the elastic clips 300 remain in the threaded recesses 220 due to the obstruction of the threaded protrusions 210 on the exhaust pipe 220, thus achieving the engagement of the elastic clips 300 with the threaded recesses 220 and completing the assembly of the exhaust pipe 200 and the duct 100.

[0051] Therefore, the exhaust assembly provided in this embodiment directly connects the exhaust pipe 200 and the air duct 100 by plugging them together, eliminating the need for a joint between them. This not only reduces the number of parts and simplifies the assembly process, but also allows for easy assembly by simply inserting the exhaust pipe 200 into the air duct 100. Compared to screwing, this method is easier to operate and has higher assembly efficiency.

[0052] Preferably, the exhaust pipe 200 can be inserted into the air outlet 110 of the air duct 100. Correspondingly, the elastic buckle 300 protrudes towards the inside of the air duct 100. During assembly, the exhaust pipe 200 is inserted into the air outlet 110 and pushed in forcefully to complete the assembly. When the threaded protrusion 210 on the exhaust pipe 200 moves to the position opposite to the elastic buckle 300, the exhaust pipe 200 can cooperate with the elastic buckle 300 to produce a slight recoverable deformation, making the insertion easier and smoother. After the threaded protrusion 210 with slight deformation passes the elastic buckle 300, it can return to its original shape on its own. In this way, the threaded protrusion 210 can exert its own limiting effect on the elastic buckle 300. Of course, it is also possible for the exhaust pipe 200 not to deform and to rely solely on the deformation of the elastic buckle 300.

[0053] Specifically, an expansion joint 120 can be provided in the area of ​​the air duct 100 around the elastic buckle 300. The presence of the expansion joint 120 can reduce the restriction of the freedom of the elastic buckle 300 on the side wall of the air duct 100. The part of the elastic buckle 300 opposite to the expansion joint 120 can undergo elastic deformation within the space enclosed by the expansion joint 120. That is, part of the structure of the elastic buckle 300 can deform towards the outside of the air duct 100 under the compression of the exhaust pipe 200 inside the air duct 100, resulting in better elastic performance.

[0054] Preferably, the aforementioned expansion joint 120 can be configured as a U-shaped joint, with the U-shaped opening of the U-shaped joint facing inwards towards the air duct 100 along the axial direction of the air outlet 110. This allows the elastic buckle 300 to deform around its bottom connection to the air duct 100, improving its performance. Correspondingly, the elastic buckle 300 can be configured as a rectangular structure, with three sides of the elastic buckle 300 facing the expansion joint 120, suspending it, and the other side of the elastic buckle 300 connected to the air duct 100. This allows the elastic buckle 300 to elastically deform around its connection to the air duct 100. It should be noted that when the air outlet 110 of the air duct 100 faces upwards and its central axis 130 is vertically aligned, the U-shaped opening of the U-shaped joint faces downwards.

[0055] The top surface of the elastic buckle 300 facing the outside of the air duct 100 is defined as the guide surface 310. This guide surface 310 is set to be inclined from the outside to the inside towards the central axis 130 of the air outlet 110 along the axial direction of the air outlet 110. When the threaded protrusion 210 on the exhaust pipe 200 moves to a position opposite to the elastic buckle 300, the bottom surface of the threaded protrusion 210 (i.e., the surface facing the inside of the air duct 100) will first contact the guide surface 310 of the elastic buckle 300. Under the action of external thrust, the bottom surface of the threaded protrusion 210... A compressive force is generated between the elastic buckle 300 and the guide surface 310. This compressive force is decomposed into a component force along the guide surface 310 and a component force perpendicular to the guide surface 310. Under the action of the component force perpendicular to the guide surface 310, the elastic buckle 300 undergoes elastic deformation toward the outside of the air duct 100, leaving space for the threaded protrusion 210 to pass through. Under the action of the component force along the guide surface 310, the threaded protrusion 210 continues to move inward, making assembly easier and reducing the damage to the structure caused by the aforementioned compressive force.

[0056] The bottom surface of the elastic buckle 300 facing the inside of the air duct 100 is defined as the limiting surface 320. The limiting surface 320 can be inclined from the inside to the outside towards the central axis 130 of the air outlet 110 along the axial direction of the air outlet 110. The angle between the limiting surface 320 of the elastic buckle 300 and the central axis 130 of the air outlet 110 is set to 80-90°. That is, the angle between the limiting surface 320 and the surface perpendicular to the axial direction of the air outlet 110 is 0-10°. When the angle between the limiting surface 320 and the surface perpendicular to the axial direction of the air outlet 110 is 0°, the limiting surface 320 is perpendicular to the axial direction of the air outlet 110. Thus, when the exhaust pipe 200 is inserted into place, the limiting surface 320 of the elastic clip 300 can effectively limit the threaded protrusion 210 on the exhaust pipe 200, meaning the elastic clip 300 is less prone to large deformation, and the threaded protrusion 210 is less likely to overshoot the elastic clip 300. This ensures the secure assembly of the exhaust pipe 200 and the duct 100. When the limiting surface 320 is tilted, it increases the contact area between the limiting surface 320 of the elastic clip 300 and the top surface of the threaded protrusion 210, reducing local pressure and preventing damage to the elastic clip 300 and the exhaust pipe 200 due to excessive local pressure.

[0057] It should be noted that the top and bottom surfaces of the elastic buckle 300 are not strictly upper and lower surfaces, but are defined as top and bottom surfaces for descriptive purposes only, and are set back to back.

[0058] Specifically, the angle between the guide surface 310 of the elastic buckle 300 and the central axis 130 of the air outlet 110 is smaller than the angle between the limiting surface 320 and the central axis 130 of the air outlet 110. That is, the angle between the guide surface 310 and the surface perpendicular to the axial direction of the air outlet 100 is greater than the angle between the limiting surface 320 and the surface perpendicular to the axial direction of the air outlet 100. This ensures the guiding effect of the guide surface 310 and the limiting effect of the limiting surface 320. The angle between the guide surface 310 and the central axis 130 of the air outlet 110 can be set to a range of 50–80°. In other words, the angle between the guide surface 310 and the surface perpendicular to the axial direction of the air outlet 110 is set to a range of 10–40°. This means the guide surface 310 has a guiding slope of 10–40°. Under this larger guiding slope, the exhaust pipe 200 can be smoothly inserted into the air outlet 110 of the duct 100. It should be noted that when the air outlet 110 of the air duct 100 faces upward and the central axis 130 of the air outlet 110 is set vertically, the angle between the guide surface 310 and the horizontal plane is 10 to 40°, and the angle between the limiting surface 320 and the horizontal plane is 0 to 10°.

[0059] In addition to the guide surface 310 and the limiting surface 320 mentioned above, the elastic buckle 300 also has two end faces 330. These two end faces 330 are located at both ends of the elastic buckle 300 along the circumference of the air outlet 100. A chamfer or rounded corner 331 is provided on the side of at least one of the two end faces 330 facing the central axis 130 of the air outlet 110. In this way, the chamfer or rounded corner 331 can form a guide structure for the exhaust pipe 200 to be screwed out. When it is necessary to remove the exhaust pipe 200, the top surface of the threaded protrusion 210 of the exhaust pipe 200 can be smoothly rotated under the guidance of the chamfer or rounded corner 331 on the end face of the elastic buckle 300. Thus, the exhaust pipe 200 can be removed by screwing on the thread. The presence of the chamfer or rounded corner 331 can also prevent the exhaust pipe 200 from being scratched by sharp corners. It should be noted that when the air outlet 110 of the air duct 100 faces upward and the central axis 130 of the air outlet 110 is vertically set, both end faces 330 of the elastic buckle 300 are vertically set.

[0060] Preferably, chamfers or fillets 331 are provided on both end faces 330 of the elastic buckle 300 to accommodate left-hand and right-hand threads.

[0061] At least two elastic clips 300 can be provided, and the elastic clips 300 can be arranged at intervals along the circumference of the air outlet 110 of the air duct 100. In this way, the assembly reliability and force balance of the exhaust pipe 200 can be improved, and the exhaust pipe 200 is not easy to fall out. The number of elastic clips 300 can be set to 2 to 6, and it is preferable that the elastic clips 300 are evenly arranged along the circumference of the air outlet 110 of the air duct 100.

[0062] Preferably, the elastic buckle 300 and the air duct 100 are made into an integral structure, which can improve the structural reliability.

[0063] A protective net 400 can be installed inside the air outlet 110 of the air duct 100. This protective net 400 can block the exhaust pipe 200 to prevent it from being over-aligned during assembly. Furthermore, the protective net 400, in conjunction with the elastic clip 300, can improve the stability of the exhaust pipe 200 assembly, preventing it from shaking. Additionally, the protective net 400 can prevent personnel from touching the rotating fan blades inside the air duct 100 after the exhaust pipe 200 is removed, ensuring safety. Preferably, the distance between the bottom surfaces of the protective net 400 and the elastic clip 300 is set to 20–60 mm, meaning the length of the exhaust pipe 200 between the elastic clip 300 and the protective net 400 is 20–60 mm, facilitating the stability of the exhaust pipe 200.

[0064] Specifically, the exhaust pipe 200 is configured as a spiral telescopic pipe, so that after the exhaust pipe 200 comes into contact with the protective net 400, a certain amount of contraction and elastic deformation can occur, which can further improve the stability of the exhaust pipe 200 and prevent the protective net 400 from being squeezed and deformed by the exhaust pipe 200.

[0065] Preferably, at least a portion of the protective net 400 and the air duct 100 are integrally formed, which facilitates further reduction of the number of parts, saves assembly steps of the protective net 400 and the air duct 100, improves assembly efficiency, and enhances the connection reliability of the protective net 400 and the air duct 100.

[0066] See Figure 1 and Figure 4 This embodiment also provides a portable air conditioner, which includes the above-mentioned exhaust assembly, with the air outlet 110 of the air duct 100 facing upwards.

[0067] The portable air conditioner provided in this embodiment, in addition to having all the advantages of the above-mentioned exhaust components and high assembly efficiency, has an upward-facing air outlet 110 of its air duct 100, allowing the exhaust pipe 200 to be installed in the factory. Thus, users can use it directly after unpacking, eliminating the need for users to install the exhaust pipe 200, resulting in a better user experience.

[0068] In summary, the embodiments of the present invention disclose an exhaust assembly and a portable air conditioner, which overcomes many technical defects of traditional portable air conditioner exhaust assemblies. The exhaust assembly and portable air conditioner provided by the embodiments of the present invention have fewer parts, higher assembly efficiency, and a better user experience.
