The air outlet 460 is directly processed on the first inner shell 411 of the plastic part. There is no need to process the air outlet on the first outer shell 421, which facilitates processing and manufacturing. It also helps to simplify the installation alignment between the first inner shell 411 and the first outer shell 421. In the positive structure, the first housing 421 does not need to be designed as an escape opening structure to avoid the air outlet 460 .

In some embodiments of the present application, based on the "7"-shaped structure of the electric control box 400, the bottom wall of the insulating inner shell 410 includes a first insulating bottom wall 481, a second insulating bottom wall 482, and a third insulating bottom wall 483.

The air outlet in different directions helps In order to improve the heat dissipation airflow, it quickly leaves the electric control box 400 and is discharged from the outdoor unit with the fan, thereby improving the heat dissipation efficiency.

In some embodiments of the present application, referring to FIG. 11 , the air outlet 460 on the second insulating bottom wall 482 is formed by a plurality of elongated openings, and a water blocking portion is provided above each opening, denoted as a second water blocking portion 454 , since the second insulating bottom wall 482 is in a vertical state, there is a risk that external water enters the electric control box 400 through the air outlet on the second insulating bottom wall 482. Waterproofing is effectively achieved through the second water blocking portion 454.

In some embodiments of the present application, on the basis of improving the heat dissipation air path of the electric control box 700 itself for back side air inlet and bottom side air outlet, the heat dissipation air path of the electric control box 400 is connected to the heat dissipation air path of the outdoor unit 200.

Since the electric control box 400 is arranged close to the back panel 250, and the rear of the electric control box 400 is provided with air inlets (specifically, the first air inlet 451 and the second inlet) air inlet 452), then part of the cold air entering from the outdoor rear air inlet 213 directly enters the interior of the electric control box 400 through the air inlets (referring to the first air inlet 451 and the second air inlet 452), and then passes through the air outlet 460 at the bottom of the electric control box 400. It flows out and takes away the heat inside the electric control box 400. The hot air flowing out from the bottom of the electric control box 400 is discharged from the outdoor unit along with the heat dissipation airflow of the outdoor unit 200, which helps to further improve the discharge of the heat dissipation airflow of the electric control box 400 and improve Heat dissipation efficiency.

The first air inlet 451 is arranged to face the outdoor rear air inlet 213. The cold air flowing in from the outdoor rear air inlet 213 directly flows into the first air inlet 451, which helps to increase the amount of cold air flowing into the electric control box 400 and improve the heat dissipation effect.

There is a gap between the bottom of the electric control box 400 and the chassis 270, and the gas flowing out from the air outlet 460 at the bottom of the electric control box 400 is discharged through the gap to prevent the chassis 270 from blocking the discharge of heat dissipation gas.

Combining the cooling airflow of the electric control box 400 with the cooling airflow of the outdoor unit 200, on the one hand, the outdoor cold air can enter the interior of the electric control box 400 quickly and in large quantities; on the other hand, the hot air discharged from the bottom of the electric control box 400 can It is quickly discharged along with the heat dissipation airflow of the outdoor unit 200 without being blocked by the chassis 270, thereby achieving the effect of rapid heat dissipation of the electric control box 400.
