As shown in fig. 1, in one embodiment, the air conditioner 1 includes a fresh air device 10 and a fresh air duct structure 20. The fresh air device 10 is used for enabling airflow to flow. The fresh air duct structure 20 is connected with the fresh air device 10, so that the fresh air device 10 can drive outdoor air to the indoor environment through the fresh air duct structure 20. The fresh air duct structure 20 is the fresh air duct structure 20 in any of the following embodiments.

As shown in fig. 2, in one embodiment, the fresh air duct structure 20 includes a through-wall duct 210 and an indoor component 220. The wall penetrating pipe 210 is used for being embedded into a mounting hole of a wall body, and one end, close to the indoor, of the wall penetrating pipe 210 is used for being connected with the indoor component 220. The indoor unit 220 includes a connection head 230 and an air inlet duct 240. From the outdoor to the indoor, the wall penetrating pipe 210, the connector 230 and the air inlet pipe 240 are connected in sequence, and the air inlet pipe 240 is connected with the fresh air device 10, so that the fresh air device 10 can introduce the outdoor air into the indoor by using a channel formed by the wall penetrating pipe 210, the connector 230 and the air inlet pipe 240.

As shown in fig. 2 and 3, in particular, the through-wall duct 210 includes a junction duct section 211 and 8 tube sheets 212. An end of the transition pipe section 211 near the indoor side is used for connecting with the indoor part 220. One end of each of the plurality of segments 212 is connected to one end of the transition tube section 211 near the outdoor side and is distributed along the circumferential direction of the transition tube section 211. The opposite ends of the plurality of tube sheets 212 converge radially inward along the tube 210 with a gap between the plurality of tube sheets 212 in the assembled position of the inline stack.

The inline pipe group is a variety of pipes passing through the wall pipe 210, and includes one or more of an inline pipe, a drain pipe, an inline line, and the like.

Referring to fig. 2 and 3, in particular, the adapter tube section 211 is a cylindrical tube. The end face of each segment 212 at the end connected to adapter tube section 211 is a portion (i.e., a portion of an annulus) of the end face of adapter tube section 211 so that it can interface with adapter tube section 211. 8 pipe pieces 212 enclose a circle on the end face of the adapter pipe section 211, and one end, away from the adapter pipe section 211, of the pipe pieces 212 gathers inwards, so that a taper pipe can be regarded as being formed by the plurality of pipe pieces 212 as a whole, or a reducing pipe with a pipe diameter reduced from one end close to the adapter pipe section 211 to one end away from the adapter pipe section 211. And a gap is provided between two adjacent segments 212. In other words, the structure formed by the plurality of segments 212 may be considered as a structure formed by removing a portion of the sidewall of the cone.

During use of the through-wall tube 210, the plurality of tube sheets 212 are integrally a conical tube, and a gap is formed between two tube sheets 212. Therefore, the gathered end of the plurality of pipe pieces 212 is convenient for preliminary butt joint with the mounting hole, and plays a guiding role in the process that the wall penetrating pipe 210 extends into the mounting hole, so that the wall penetrating pipe 210 can be more conveniently mounted into the mounting hole.

And, the gap between two adjacent tube sheets 212 forms an air intake area at the side of the through-wall pipe 210, so that the air flow can enter the through-wall pipe 210 from the gap between the tube sheets 212. The air intake area formed at the side of the wall penetrating pipe 210 is not shielded by the on-line pipe group in the wall penetrating pipe 210, so that the air intake effect of the wall penetrating pipe 210 can be ensured.

The number of segments 212 may be four, five, etc. Further, the segments 212 may or may not be the same size.

It is also noted that the width of the gap between the segments 212 may be uniform throughout or may vary from end to end.

In addition, it should be noted that the through-wall pipe 210 may be located completely in the wall, or a part of the pipe segment 211 may extend into the room, or a part of the pipe segment 212 may extend out of the room.

Referring to FIG. 3, in one embodiment, plurality of tube sheets 212 can be flared outwardly relative to the end that is itself coupled to adapter tube section 211. Specifically, the plurality of segments 212 have some elasticity. Therefore, in the use of the wall penetrating pipe 210, when the overall outer diameter of the inline pipe set is larger than the diameter of the gathered ends of the plurality of pipe pieces 212, the inline pipe set can spread the plurality of pipe pieces 212 when extending out from the gathered ends of the plurality of pipe pieces 212.

In the scheme of this embodiment, wall bushing 210 can cooperate with the great online nest of tubes of pipe diameter, on the basis of guaranteeing wall bushing 210's air inlet effect, has improved wall bushing 210's suitability. Moreover, the gaps among the plurality of expanded pipe pieces 212 can be enlarged, thereby improving the air inlet effect.

It should be noted that, under the condition that the segments 212 can be expanded outward, there may be no gap between the segments 212 at the initial position, and the diameter of the online pipe group is ensured to be larger than the diameter of the gathering end of the segments 212, so that the gap may also be formed after assembly.

Preferably, the maximum width of the gaps between the plurality of tube sheets 212 is 2 mm or less. Specifically, in the case where the tube sheets 212 are fixed, the maximum width of the gap between the tube sheets 212 is 2 mm or less. In the case where the tube sheet 212 can be expanded, the maximum width of the gap formed after the expansion of the tube sheet 212 is 2 mm or less. The maximum width to the clearance limits, can prevent that big particulate matter or worm from getting into the wall pipe on guaranteeing the basis of air inlet effect.

Referring to fig. 2, one end of the connector 230 is connected to the indoor end of the transition duct section 211, and the other end is used to connect to the air inlet duct 240, thereby connecting the wall duct 210 and the air inlet duct 240. Specifically, a channel is formed inside the connector 230, and after the connector 230 is connected to the wall penetrating pipe 210, the channel inside the connector 230 is communicated with the channel inside the wall penetrating pipe 210. After the connection head 230 is connected to the air inlet pipe 240, the passage inside the connection head 230 is communicated with the passage inside the air inlet pipe 240.

It will be appreciated by those skilled in the art that the flexible air inlet duct 240 can be connected to the wall duct 210 by the connectors 230 by providing connectors 230 between the wall duct 210 and the air inlet duct 240. That is, the soft air inlet pipe 240 does not need to extend into the wall penetrating pipe 210 together with the on-line pipe set, so as to prevent the air inlet pipe 240 from being extruded and deformed, thereby ensuring the air inlet area of the air inlet pipe 240 and avoiding affecting the air inlet effect of the air inlet pipe 240.

It should be noted that in other embodiments of the present application, the indoor unit 220 may not have the connector 230, i.e., the air inlet duct 240 is directly connected to the wall duct 210.

As shown in fig. 4 and 5, further, the connection head 230 includes a first connection section 231 having a tubular shape, the first connection section 231 is embedded in the junction pipe section 211 to be connected with the junction pipe section 211, and a sectional area of the first connection section 231 is smaller than a sectional area of the junction pipe section 211.

As shown in fig. 2, 4 and 5, the first connection segment 231 has a semicircular sectional shape. That is, the first connection section 231 is a semicircular pipe. Also, the arcuate outer surface of the first connection section 231 can conform to the inner surface of the adapter tube section 211. Therefore, when the first connection section 231 is embedded in the junction section 211, the first connection section 231 occupies half of the opening of the junction section 211 for the opening of the junction section 211 near the indoor end. The inline pipe group may protrude into the wall pipe 210 from an opening portion not occupied by the first connection section 231.

It will be appreciated by those skilled in the art that by making the cross-sectional area of the first connection section 231 smaller than the cross-sectional area of the junction section 211, an installation space can be reserved for the inline tube set, and the first connection section 231 and the junction section 211 can form a clamping effect on the connection tube set, which helps to improve the stability of the installation of the inline tube set.

It should be noted that the cross section of the first connection segment 231 may have other shapes. For example, only one circular area is left. Specifically, a plane where an opening of the adapter tube section 211 near one indoor end is located is used as a reference surface, a projection of the first connection section 231 assembled in place with the adapter tube section 211 on the reference surface falls within an opening range of the adapter tube section 211, and a circular area is left after the projection range of the first connection section 231 is removed from the opening range of the adapter tube section 211.

In addition, it should be noted that the end of the connector 230 connected to the adapter tube section 211 may also correspond to the tube diameter of the adapter tube section 211. That is to say, the outer diameter of the end of the connector 230 connected to the adapter tube section 211 is matched with the inner diameter of the adapter tube section 211, so that the adapter tube section 211 is sleeved on the periphery of the connector 230; or, the inner diameter of the end of the connector 230 connected to the adapter tube section 211 is matched with the outer diameter of the adapter tube section 211, so that the connector 230 is sleeved on the periphery of the adapter tube section 211. Then, the inner channel of the connector 230 is divided into two parts, which are used for connecting the line pipe set and the air inlet pipe 240 respectively.

Referring to fig. 2 and 5, the connection head 230 includes a second connection segment 232. The second connection section 232 is tubular, the second connection section 232 is connected with the air inlet pipe 240, and the sectional area of the second connection section 232 is larger than that of the first connection section 231.

Referring to fig. 2 to 5, specifically, the second connection section 232 is a section of cylindrical pipe, and the second connection section 232 is sleeved on the outer periphery of the air inlet pipe 240. The sectional area of the second connection section 232 is larger than that of the first connection section 231, which is helpful for the second connection section 232 to connect with the air inlet pipe 240 with a larger diameter, thereby ensuring the air inlet effect of the air inlet pipe 240.

As shown in fig. 2 to 5, further, the connection head 230 includes an inclined section 233, and both ends of the inclined section 233 are respectively connected to the first connection section 231 and the second connection section 232, so that a projection of the second connection section 232 in the end face of the adapter tube section 211 falls within a projection range of the first connection section 231 in the end face of the adapter tube section 211.

Specifically, with a plane where an opening of the adapter tube section 211 near the indoor end is located as a reference plane, a projection of the second connection section 232 of the connector 230, which is assembled with the adapter tube section 211 in place, on the reference plane has a portion that falls within the opening range of the adapter tube section 211 and a portion that falls outside the opening range of the adapter tube section 211. And for the portion of the projection that falls within the opening range of the coupling segment 211, it falls within the projection range of the first connection segment 231 on the reference surface.

Referring to fig. 4, that is, the second connection section 232 does not block the opening of the adapter tube section 211 not occupied by the first connection section 231, thereby facilitating the installation of the inline tube set.

Although not shown, in one embodiment, an elastomeric screen is positioned between adjacent segments 212. So that some small particles or small flying insects can be prevented from entering the through-wall pipe 210.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made to the invention consistent with the principles of the invention, which may be directly determined or derived from the disclosure of the present invention, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
