[0051] Combine the following Figure 1 An air conditioner according to the present embodiment will be described in detail. Figure 1 It is a structural schematic diagram of an indoor unit in an air conditioner according to an embodiment of the utility model.

[0052] Reference Figure 1 In the present embodiment, since the air conditioner includes the fresh air duct assembly 200 of the following embodiment, the beneficial technical effects of the fresh air duct assembly 200 in the following embodiment are also possessed by the air conditioner in the present embodiment.

[0053] Reference Figure 1 In this embodiment, the air conditioner includes an indoor unit 100 for being arranged in an indoor space.

[0054] In this embodiment, the air conditioner further includes an outdoor unit for being arranged in an outdoor space, and the indoor unit 100 and the outdoor unit are connected via a connecting pipe.

[0055] In this embodiment, the air conditioner may be a floor-standing air conditioner or a wall-mounted air conditioner.

[0056] Combine the following Figures 2 to 8 The fresh air duct assembly 200 of the air conditioner of this embodiment will be described in detail. Figure 2 This is a schematic structural diagram of a fresh air assembly according to an embodiment of the utility model; Figure 3 is a partial exploded schematic diagram of a fresh air assembly according to an embodiment of the utility model; Figure 4 yes Figure 3 The enlarged schematic diagram of "A" in FIG. Figure 5 yes Figure 3 The enlarged schematic diagram of "B" in FIG. Figure 6 It is a schematic diagram of the structure of the first transfer tube 223, the second transfer tube 224 or the third transfer tube 227 in the fresh air assembly according to an embodiment of the utility model; Figure 7 It is a structural schematic diagram of a retaining ring 225 in a fresh air assembly according to an embodiment of the utility model; Figure 8 It is an exploded schematic diagram of a retaining ring 225 in a fresh air assembly according to an embodiment of the utility model.

[0057] Reference Figure 2 In this embodiment, the fresh air duct assembly 200 includes a first wall-penetrating tube 210 and a wall-penetrating member 220. The first wall-penetrating tube 210 is used to be connected to the indoor unit 100, and the first wall-penetrating tube 210 is used to be penetrated through the first wall hole of the first wall; the wall-penetrating member 220 includes a second wall-penetrating tube 221 and a first telescopic bending tube 222, and the second wall-penetrating tube 221 is used to be penetrated through the second wall hole of the second wall; the first telescopic bending tube 222 is connected between the first wall-penetrating tube 210 and the second wall-penetrating tube 221, and the first telescopic bending tube 222 is used to allow the distance between the first wall-penetrating tube 210 and the second wall-penetrating tube 221 to be adjusted and the angle between them to be adjusted.

[0058] Since the fresh air duct assembly 200 of this embodiment includes a first through-wall tube 210 that can pass through the first wall and a second through-wall tube 221 that can pass through the second wall, and a first telescopic bending tube 222 is connected between the first through-wall tube 210 and the second through-wall tube 221, the first telescopic bending tube 222 can well adapt to the distance between the first through-wall tube 210 and the second through-wall tube 221 and the angle between the first through-wall tube 210 and the second through-wall tube 221. Therefore, the fresh air duct assembly 200 of this embodiment can be installed on at least two walls, and can adapt to the installation space size or installation distance between at least two walls and the angle between the two walls, so as to meet the installation requirements of users and improve user experience.

[0059] In addition, compared to ordinary air conditioners, air conditioners with fresh air function not only need to drill a through hole on the wall for the online pipe, but also need to drill another hole for the fresh air duct to install the fresh air duct. However, drilling an extra hole on the wall will again damage the appearance of the wall, making the indoor space unsightly, and again reducing the user experience.

[0060] Reference Figure 2 and Figure 3 In this embodiment, the cross-sections of the first wall-penetrating tube 210 and the second wall-penetrating tube 221 are both semicircular, so as to allow the first wall-penetrating tube 210 and the online tube to pass through the first wall hole together, and the second wall-penetrating tube 221 and the online tube to pass through the second wall hole together.

[0061] It is understandable that by setting the cross-sections of the first through-wall tube 210 and the second through-wall tube 221 to be semicircular, a space for the online tube to pass through can be left in the first through-wall hole and the second through-wall hole, so that the first through-wall tube 210 and the online tube can pass through / or be installed in the first through-wall hole together, and the second through-wall tube 221 and the online tube can pass through / or be installed in the second through-wall hole together. Furthermore, when installing the air conditioner having the fresh air duct assembly 200 of this embodiment, only one through hole can be drilled in the wall to complete the installation. The degree of damage to the wall surface is reduced, the aesthetics of the indoor space is ensured, and the user experience is ensured.

[0062] Reference Figure 2 and Figure 3 In this embodiment, the cross-sectional area of ​​the first telescopic bending tube 222 is greater than the cross-sectional area of ​​the first wall-penetrating tube 210, and the cross-sectional area of ​​the first telescopic bending tube 222 is greater than the cross-sectional area of ​​the second wall-penetrating tube 221; and the wall-penetrating component 220 also includes a first transfer tube 223 and a second transfer tube 224.

[0063] Reference Figure 2 and Figure 3 In this embodiment, the first transfer tube 223 includes a first telescopic connection section 2231, a first contraction section 2232 and a first wall-penetrating connection section 2233. The first telescopic connection section 2231 is connected to the first telescopic bending tube 222, the first wall-penetrating connection section 2233 is connected to the first wall-penetrating tube 210, the first contraction section 2232 is connected between the first telescopic connection section 2231 and the first wall-penetrating connection section 2233, the cross-sectional area of ​​the first telescopic connection section 2231 is greater than the cross-sectional area of ​​the first wall-penetrating connection section 2233, and the cross-sectional area of ​​the first contraction section 2232 decreases from the first telescopic connection section 2231 to the first wall-penetrating connection section 2233.

[0064] Reference Figure 2 and Figure 3 In this embodiment, the second transfer tube 224 includes a second telescopic connection section 2241, a second contraction section 2242 and a second wall-penetrating connection section 2243. The second telescopic connection section 2241 is connected to the first telescopic bending tube 222, the second wall-penetrating connection section 2243 is connected to the second wall-penetrating tube 221, the second contraction section 2242 is connected between the second telescopic connection section 2241 and the second wall-penetrating connection section 2243, the cross-sectional area of ​​the second telescopic connection section 2241 is greater than the cross-sectional area of ​​the second wall-penetrating connection section 2243, and the cross-sectional area of ​​the second contraction section 2242 decreases from the second telescopic connection section 2241 to the second wall-penetrating connection section 2243.

[0065] It is understandable that in order to minimize the damage to the wall and ensure the intake of fresh air, the cross-sectional area of ​​the first telescopic curved tube 222 can be set to be larger than the cross-sectional area of ​​the first wall-penetrating tube 210, and the cross-sectional area of ​​the first telescopic curved tube 222 can be set to be larger than the cross-sectional area of ​​the second wall-penetrating tube 221. However, in this way, there will be a difference in the cross-sectional dimensions of the first telescopic curved tube 222 and the first wall-penetrating tube 210 and the second wall-penetrating tube 221, which will make it difficult to connect the first telescopic curved tube 222 and the first wall-penetrating tube 210 and the second wall-penetrating tube 221, and reduce the fluidity of the fresh air flow therein.

[0066] Furthermore, the first transfer tube 223 includes a first wall-penetrating connection section 2233 connected to the first wall-penetrating tube 210, a first telescopic connection section 2231 connected to the first telescopic bending tube 222, and a first contraction section 2232 connected between the first telescopic connection section 2231 and the first wall-penetrating connection section 2233, and the cross-sectional area of ​​the first contraction section 2232 decreases from the first telescopic connection section 2231 to the first wall-penetrating connection section 2233, so that the first transfer tube 223 can ensure the convenience of connection between the first telescopic bending tube 222 and the first wall-penetrating tube 210, and ensure the fluidity of the airflow when it flows from the first telescopic bending tube 222 to the first wall-penetrating tube 210.

[0067] Based on the same reason, the first transfer tube 223 can ensure the convenience of connection between the first telescopic tube and the second wall-penetrating tube 221 , and ensure the fluidity of the airflow when it flows from the second wall-penetrating tube 221 to the first telescopic tube.

[0068] Furthermore, by disposing the first contraction section 2232 and the second contraction section 2242 , the fluidity of the airflow in the first transfer tube 223 and the second transfer tube 224 can be ensured.

[0069] Reference Figure 2 and Figure 3 In this embodiment, the first telescopic bending tube 222 is a corrugated tube.

[0070] It is understandable that the first telescopic bending tube 222 can be a corrugated tube, thereby meeting the requirements of allowing the distance between the first wall-penetrating tube 210 and the second wall-penetrating tube 221 to be adjusted and the angle between the first wall-penetrating tube 210 and the second wall-penetrating tube 221 to be adjusted.

[0071] In some other embodiments, the first telescopic bending tube 222 may be a rubber tube, a metal hose, or an aluminum tube or a copper tube with good ductility, which can also meet the requirements of allowing the distance between the first wall-penetrating tube 210 and the second wall-penetrating tube 221 to be adjusted and the angle between the first wall-penetrating tube 210 and the second wall-penetrating tube 221 to be adjusted.

[0072] Reference Figure 2 , Figure 3 and Figure 6 In this embodiment, the shape of the cross section of the first telescopic bending tube 222 is the same as the shape of the cross section of the first telescopic connecting section 2231 and the shape of the cross section of the second telescopic connecting section 2241, and the cross-sectional area of ​​the first telescopic bending tube 222 is less than or equal to the cross-sectional area of ​​the first telescopic connecting section 2231, and the cross-sectional area of ​​the first telescopic bending tube 222 is less than or equal to the cross-sectional area of ​​the second telescopic connecting section 2241. The inner side walls of the first telescopic connecting section 2231 and the second telescopic connecting section 2241 are provided with a thread groove 2246, which is matched and connected with the corrugated structure of the first telescopic bending tube 222 to limit the axial movement of the first telescopic bending tube 222.

[0073] It should be understood that the connection between the first telescopic bending tube 222 and the first transfer tube 223 and the second transfer tube 224 is that one end of the first telescopic bending tube 222 can be directly extended into the first telescopic connecting section 2231 of the first transfer tube 223, and the other end of the first telescopic bending tube 222 can be directly extended into the second telescopic connecting section 2241 of the second transfer tube 224, so as to ensure the convenience of connection between the first telescopic bending tube 222 and the first transfer tube 223 and the second transfer tube 224.

[0074] At the same time, in order to fix the connection between the first telescopic bending tube 222 and the first transfer tube 223 and the second transfer tube 224, a threaded groove 2246 can be set on the inner wall of the first telescopic connecting section 2231 of the first transfer tube 223 and the inner wall of the second telescopic connecting section 2241 of the second transfer tube 224. The threaded groove 2246 is connected in coordination with the corrugated structure of the first telescopic bending tube 222, so that the connection stability of the first telescopic bending tube 222 and the first transfer tube 223 and the second transfer tube 224 can be ensured.

[0075] Reference Figure 6 In this embodiment, the first adapter tube 223 includes a first adapter shell 2234 and a second adapter shell 2235 which are radially interlocked with each other, a hook 2236 is provided on the inner side wall of the first adapter shell 2234, and a buckle 2237 is provided at the position of the second adapter shell 2235 corresponding to the hook 2236, and the hook 2236 is locked in the buckle 2237.

[0076] It can be understood that the first adapter tube 223 is a detachable structure of the first adapter shell 2234 and the second adapter shell 2235. Compared with an integrated structure, when the first telescopic tube is installed in the first adapter tube 223, the first adapter shell 2234 and the second adapter shell 2235 can be directly buckled on the first telescopic bending tube 222, ensuring the convenience of connecting the first telescopic bending tube 222 and the first adapter tube 223. Especially when the distance between the first wall and the second wall is short or the space is narrow, the detachable structure of the first adapter tube 223 can greatly reduce the difficulty of installing the first telescopic bending tube 222 and the first adapter tube 223.

[0077] In addition, the first adapter shell 2234 and the second adapter shell 2235 can be connected by a flexible rope to effectively reduce the probability of the first adapter shell 2234 or the second adapter shell 2235 falling when the detachable first adapter tube 223 is assembled and installed with the first telescopic bending tube 222. Especially when high-altitude installation is required, it greatly ensures that the installation of the new air duct assembly 200 can be carried out smoothly.

[0078] Reference Figure 6 In this embodiment, the structure of the second transfer tube 224 is the same as that of the first transfer tube 223 .

[0079] Specifically, the second transfer tube 224 can also be configured to include two transfer shells that are radially buckled and connected to each other, and further, hooks 2236 and buckles 2237 can be respectively provided on the two shells to achieve connection. Therefore, the connection convenience of the first telescopic bending tube 222 and the second transfer tube 224 can be ensured, and the installation difficulty of the first telescopic bending tube 222 and the first transfer tube 223 can be reduced. At the same time, a flexible rope can be connected between the two transfer shells to ensure that the installation of the new air duct assembly 200 can be carried out smoothly.

[0080] Reference Figure 2 and Figure 3 In this embodiment, the shape of the cross section of the first wall-penetrating tube 210 is the same as the shape of the cross section of the first wall-penetrating connecting section 2233, and the cross-sectional area of ​​the first wall-penetrating tube 210 is greater than or equal to the cross-sectional area of ​​the first wall-penetrating connecting section 2233, and the first wall-penetrating connecting section 2233 is arranged in the first wall-penetrating tube 210.

[0081] It is understandable that the first transfer tube 223 and the first wall-penetrating tube 210 may be connected in a manner that the first wall-penetrating connecting section 2233 of the first transfer tube 223 is extended into the first wall-penetrating tube 210 .

[0082] In this embodiment, in order to ensure the connection stability between the first adapter tube 223 and the first wall-penetrating tube 210, at least one screw hole can be opened on the wall of the first wall-penetrating tube 210, and after the first adapter tube 223 (first wall-penetrating connecting section 2233) and the first wall-penetrating tube 210 are connected in place, the screw is screwed into the screw hole to tighten and fix the first adapter tube 223 (first wall-penetrating connecting section 2233) and the first wall-penetrating tube 210.

[0083] Reference Figure 2 , Figure 3 and Figure 4 In some other embodiments, a first locking protrusion 2238 is provided on the outer wall of the first through-wall connecting section 2233, and a first locking hole 2239 is opened in the first through-wall tube 210 at a position corresponding to the first locking protrusion 2238, and the first locking protrusion 2238 is locked in the first locking hole 2239.

[0084] It is understandable that, by setting and matching the first engaging protrusion 2238 and the first engaging hole 2239, the connection stability between the first transfer tube 223 (first through-wall connection section 2233) and the first through-wall tube 210 can be ensured. At the same time, the installation of the first transfer tube 223 (first through-wall connection section 2233) and the first through-wall tube 210 is facilitated, and the installation difficulty of the fresh air duct assembly 200 is reduced.

[0085] Reference Figure 2 , Figure 3 In this embodiment, the shape of the cross section of the second wall-penetrating tube 221 is the same as the shape of the cross section of the second wall-penetrating connecting section 2243, and the cross-sectional area of ​​the second wall-penetrating tube 221 is greater than or equal to the cross-sectional area of ​​the second wall-penetrating connecting section 2243, and the second wall-penetrating connecting section 2243 is arranged in the second wall-penetrating tube 221.

[0086] It is understandable that the second adapter tube 224 and the second wall-penetrating tube 221 may be connected in such a way that the second wall-penetrating connecting section 2243 of the second adapter tube 224 is extended into the second wall-penetrating tube 221 .

[0087] In this embodiment, in order to ensure the connection stability between the second transfer tube 224 and the second wall-penetrating tube 221, at least one screw hole can be opened on the wall of the second wall-penetrating tube 221, and after the second transfer tube 224 (second wall-penetrating connecting section 2243) and the second wall-penetrating tube 221 are connected in place, the screw is screwed into the screw hole to tighten and fix the second transfer tube 224 (second wall-penetrating connecting section 2243) and the second wall-penetrating tube 221.

[0088] Reference Figure 2 , Figure 3 and Figure 5In some other embodiments, a second locking protrusion 2244 is provided on the outer wall of the second wall-penetrating connecting section 2243, and a second locking hole 2245 is opened in the second wall-penetrating tube 221 at a position corresponding to the second locking protrusion 2244, and the second locking protrusion 2244 is locked in the second locking hole 2245.

[0089] It is understandable that, by providing and matching the second engaging protrusion 2244 and the second engaging hole 2245, the connection stability between the second transfer tube 224 (the second through-wall connection section 2243) and the second through-wall tube 221 can be ensured. At the same time, the installation of the second transfer tube 224 (the first through-wall connection section 2233) and the second through-wall tube 221 is facilitated, and the installation difficulty of the fresh air duct assembly 200 is reduced.

[0090] Reference Figure 2 and Figure 3 In this embodiment, both ends of the first wall-penetrating tube 210 and both ends of the second wall-penetrating tube 221 are respectively provided with retaining rings 225, and the retaining rings 225 are used to be provided on both sides of the first wall-penetrating hole and both sides of the second wall-penetrating hole.

[0091] It can be understood that the setting of the protective ring 225 can ensure the aesthetics of the wall, and at the same time ensure the relative airtightness of the first wall hole and the second wall hole, so as to ensure the treatment effect (cooling effect, heating effect / fresh air effect) of the air conditioner on the air in the indoor space.

[0092] Reference Figure 7 and Figure 8 In this embodiment, the retaining ring 225 includes at least two retaining segments 2251 connected end to end to each other, one end of the retaining segment 2251 is provided with a claw 2252 extending from the end of the retaining segment 2251, and the other end of the retaining segment 2251 is provided with a clamping column 2253 extending along the axial direction of the retaining ring 225, and the clamping claw 2252 is clamped on the clamping column 2253.

[0093] It can be understood that by configuring the retaining ring 225 as a detachable structure, specifically, by configuring claws 2252 and clamping columns 2253 at the head and tail of the retaining section 2251, the retaining ring 225 can be installed on the new air duct assembly 200 after the new air duct assembly 200 is installed / assembled and passed through the first wall hole and the second wall hole.

[0094] The integrated structure needs to be put on the first wall-penetrating tube 210 and the second wall-penetrating tube 221 before installing the new air duct assembly 200 to the first wall-penetrating hole and the second wall-penetrating hole.

[0095] Furthermore, compared to the integrated retaining ring 225, the detachable retaining ring 225 can be easily installed without interfering with the assembly and installation of other components of the fresh air duct assembly 200 (for example, the first telescopic bending tube 222, the first wall-penetrating tube 210, the second wall-penetrating tube 221, the first transfer tube 223 and / or the second transfer tube 224), thereby reducing the difficulty of installing the fresh air duct assembly 200.

[0096] In addition, a locking baffle 2254 is provided at the free end of the locking column 2253 , and the locking claw 2252 is locked between the retaining ring 225 and the locking baffle 2254 to ensure the connection stability between the plurality of retaining segments 2251 .

[0097] Reference Figure 2 , Figure 3 In this embodiment, the fresh air duct assembly 200 also includes a second telescopic bending tube 226 , one end of the second telescopic bending tube 226 is connected to the indoor unit 100 , and the other end of the second telescopic bending tube 226 is connected to the first wall-penetrating tube 210 .

[0098] It should be noted that the second telescopic bending tube 226 can be made of a corrugated tube, a rubber tube, a metal hose, an aluminum tube, a copper tube, etc., just like the first telescopic bending tube 222.

[0099] It can be understood that since the distance and installation angle between the indoor unit 100 of the air conditioner and the first wall hole need to be set according to the needs of the user, and then the indoor unit 100 and the first wall pipe 210 are connected by a retractable and bendable second telescopic pipe, the fresh air duct assembly 200 can adapt to different distances and different installation angles between the indoor unit 100 and the first wall hole, so that the installation of the air conditioner can meet the diverse installation plans of users / different users, thereby ensuring user experience.

[0100] Reference Figure 2 , Figure 3 and Figure 6 In this embodiment, the fresh air duct assembly 200 also includes a third transfer tube 227 , and the third transfer tube 227 is connected between the second telescopic bending tube 226 and the first wall-penetrating tube 210 .

[0101] It is understandable that the structure of the third adapter tube 227 can be completely the same as the second adapter tube 224 / first adapter tube 223. For example, the third connecting tube can be a structure of a telescopic connection section, a contraction section and a wall-penetrating connection section, and a split structure in which two adapter shells are interlocked, and the two adapter shells are also connected with a flexible rope, and the threaded groove 2246 and the locking protrusion are set. Furthermore, the third adapter tube 227 ensures the convenience of connection between the second telescopic bending tube 226 and the first wall-penetrating tube 210, reduces the difficulty of installation between the second telescopic bending tube 226 and the first wall-penetrating tube 210, and ensures the smooth installation of the new air duct assembly 200.

[0102] In this embodiment, the number of the wall-penetrating components 220 is set to be multiple, and the multiple wall-penetrating components 220 are connected end to end in sequence.

[0103] It should be understood that when installing the air conditioner, if the fresh air duct assembly 200 needs to pass through more than three walls, the number of the wall-penetrating components 220 can be set to multiple. For example, when the fresh air duct assembly 200 needs to pass through four walls, the number of the wall-penetrating components 220 can be set to three, and on the basis of the first wall-penetrating pipe 210 passing through the first wall, the three wall-penetrating components 220 are respectively set on the remaining three walls, and the three wall-penetrating components 220 are connected in sequence and connected to the first wall-penetrating pipe 210. This allows the air conditioner to have more installation schemes, meet more installation requirements of users, and ensure user experience.

[0104] Reference Figure 2 , Figure 3 In this embodiment, a wind and rain proof structure 228 is provided at the end of the second wall-penetrating pipe 221 located in the outdoor space.

[0105] It can be understood that, by providing the wind and rainproof structure 228, it is possible to effectively prevent rainwater and airflow that is not required by the user from flowing back into the new air duct assembly 200, thereby ensuring the user experience.

[0106] Specifically, the air inlet 2281 of the second wall-penetrating pipe 221 at the end of the outdoor space is arranged downward to form a wind and rain proof structure 228 .

[0107] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
