In summary, the rain hat, the wall penetrating pipe and the fresh air pipeline system of the air conditioner provided by the utility model have the following technical effects:

1. by providing the air suction port 101 and the side air inlet 103 in the housing 100, and communicating the air suction port 101 with the side air inlet 103, the area of the air suction port 101 can be further increased, so that the air suction pressure of the air suction port 101 and the side air inlet 103 is dispersed, the pressure of rainwater is reduced, and the suction amount of rainwater is greatly reduced;

2. the inclined air inlet grille is arranged in the air suction inlet 101, so that the air inlet can be split into a plurality of sub air inlets 102, and the air inlet 101 is split into a plurality of sub air inlets 102, so that the air quantity of the air inlet can be ensured to be dispersed, the negative pressure of the air suction inlet 101 is reduced, the water suction pressure is reduced, and the suction quantity of rainwater is greatly reduced;

3. by providing the first water baffle 104 and the second water baffle 105, rainwater, a part of which is sucked by suction of the suction inlet 101, can be prevented from entering the gas passage of the housing 100;

4. by providing the insertion portion 107, the ease of installation of the housing 100 can be improved.

5. Through designing the wall pipe into two independent channels, can solve the separation of pipeline and new trend, and not increase holistic wall pipe area, be favorable to passing the less wall hole of hole.

The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
