At present, the purpose of improving the air quality of the indoor space is achieved by introducing outdoor fresh air into the indoor space. The purpose is usually realized by configuring a fresh air module on the air conditioner, the fresh air module comprises a fresh air pipe and a fresh air machine, and under the action of the fresh air machine, outdoor fresh air enters the indoor space through the fresh air pipe, so that the purpose of improving the air quality of the indoor space is achieved. However, the fresh air duct needs to be extended to the outside through a wall, and the connecting pipe and the connecting line between the indoor unit and the outdoor unit, and the drain pipe of the indoor unit also need to be extended to the outside through a wall. When installing the air conditioner, a through-wall hole is usually reserved in the wall, and only the connecting component is usually considered in the through-wall hole. On the basis of the reasons of saving the punching cost, damaging the wall body less, being attractive and the like, the fresh air pipe can be generally considered to penetrate out of the through-wall hole, but the diameter of the fresh air pipe cannot be too large due to limited space. However, the fresh air duct with a smaller diameter can achieve a smaller fresh air intake, resulting in a limited effect of improving the air quality of the indoor space. Therefore, the first recess capable of partially accommodating the connecting assembly of the fresh air conditioner is formed in at least part of the outer side of the air pipe body, and when the air pipe body is installed, the connecting assembly is arranged at the first recess, so that the connecting assembly and the air pipe body can penetrate through the wall penetrating hole while the fresh air quantity is ensured, and the air quality of an indoor space can be better improved.

First, a possible implementation of the fresh air duct assembly of the fresh air conditioner of the present invention is explained with reference to fig. 1 to 7B.

The indoor unit of an air conditioner includes a casing 1, and a fresh air inlet (not shown) is provided in the casing 1. The indoor unit of the air conditioner is provided with a fresh air module (not shown), the fresh air module is arranged in the shell 1, and a fresh air interface is communicated with the fresh air module. The fresh air pipe assembly comprises an air pipe body 3, and the first end of the air pipe body 3 is connected with a fresh air interface through modes such as clamping, screwing and inserting, so that the air pipe body 3 is communicated with a fresh air module. The second end of the second end air pipe body 3 of the air pipe body 3 extends out of the outdoor space and is communicated with the outdoor space, so that outdoor fresh air can enter the indoor space through the air pipe body 3 and the fresh air module, and the purpose of improving the air quality of the indoor space is achieved.

A first recess 31 is formed in the circumferential outer side of the air duct body 3, and the first recess 31 can partially accommodate the coupling assembly 2. Like this, when the radial dimension of through-wall hole 6 is fixed, detach the partial space that coupling assembling 2 occupy, can the diameter of maximize tuber pipe body 3, only need set up coupling assembling 2 in first sunken 31 department to just can make coupling assembling 2 and tuber pipe body 3 pass through-wall hole 6 simultaneously when guaranteeing the fresh air volume. Through such a mode of setting, need not to punch in addition, can realize bigger draught area as far as possible through the limited space of through-wall hole 6, introduce more new trend for the interior space to can improve the air quality of interior space better.

It should be noted that the first recess 31 may be formed entirely inward along the circumferential direction of the outer side of the air duct body 3, or the first recess 31 may be formed inward only at the positions of the wall through hole 6 and the front and rear portions of the wall through hole 6. Those skilled in the art can flexibly select the forming position of the first recess 31 on the air duct body 3 according to the specific application scenario, as long as the connection assembly 2 and the air duct body 3 can simultaneously pass through the wall through hole 6 while ensuring the fresh air volume.

As shown in fig. 3 to 7B, the cross section of the air duct body 3 is crescent-shaped, and two ends of the crescent-shaped are arc segments. For example, the crescent is a bellows or a smooth tube. The both ends of ordinary crescent are set to relatively sharp-pointed shape usually, compare with ordinary crescent, and the area of the crescent of this application can be bigger some to just also increased tuber pipe body 3's draught area, can allow more new trend to pass through. When the installation, set up coupling assembling 2 in the concave surface department of crescent, make coupling assembling 2 and tuber pipe body 3 pass through wall hole 6 simultaneously, just so can allow more new trend to enter into the interior space through tuber pipe body 3 to can improve the interior space better.

To better illustrate that the cross section of the air duct body 3 is designed to be crescent-shaped to allow more fresh air to pass through, the inventor has performed a series of verification tests. As shown in fig. 7A and 7B, taking a circular hole with a diameter of 60mm of the through-wall hole 6 as an example, the cross section of the bound connecting assembly is approximately oval, and the length of the major axis of the oval is approximately 45 mm. The inventors have conducted experiments under two conditions, respectively: (1) the air duct body 3 is set to be an approximate circular tube, and the diameter of the air duct body 3 is approximately 32mm at the moment; (2) the air pipe body 3 is arranged as a crescent pipe. The results of the specific experiments are shown in table 1 below.
