So as to improve the heat exchange effect of the indoor heat exchanger on the airflow.

In some embodiments, the first, second, and third heat exchange sections are the same length as the housing 100. The first heat exchange section is close to one side of the wall body inside the shell 100, the width direction of the first heat exchange section is vertical, the second heat exchange section is inclined from bottom to top to one side of the wall body, and the bottom of the second heat exchange section is connected with the top of the first heat exchange section. The third heat exchange section inclines to one side of the wall body from top to bottom, and the top of the second heat exchange section at the top of the third heat exchange section is connected.

In some embodiments, a grille is provided at the air inlet of the air conditioner to prevent debris from entering the housing 100 through the air inlet of the air conditioner. The service life of the hanging air conditioner is prolonged.

In some embodiments, air conditioner air intake department is provided with the turn-ups, and the turn-ups sets up along the border of air conditioner air intake department, and the grid is placed on the turn-ups of air conditioner air intake department, makes things convenient for the installation of grid, can directly take off the grid from the air conditioner air intake when not needing.

In some embodiments, an air deflector is provided on the housing 100, the air deflector being proximate to the air outlet of the air conditioner. The length direction of the air-conditioning outlet is the same as the length direction of the housing 100, and the length direction of the air deflector is the same as the length direction of the air-conditioning outlet. The air deflector is turned over and used for adjusting the direction of the air flow output through the air outlet of the air conditioner.

In some embodiments, the air guide plate is located below the air outlet of the air conditioner, the air guide motor is arranged in the shell 100, an output shaft of the air guide motor is connected with the air guide plate, and the air guide motor is started to overturn the air guide plate and adjust the wind direction of the air outlet of the air conditioner.

While embodiments of the present utility model have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
