Wall-mounted air conditioner

Abstract

Provided is a wall-mounted air conditioner, including a casing and a heat exchanger. The heat exchanger is arranged in the casing; the casing is internally provided with an air duct (30); the air duct has an air inlet and an air outlet; and at least part of the air inlet is located on the front of the casing. By configuring at least part of the air inlet of the wall-mounted air conditioner to be located on the front of the casing, the air in the environment does not need to enter the air duct from directly above the casing. In this way, the distance between the wall-mounted air conditioner and an indoor top wall can be greatly reduced or eliminated, and the indoor space utilization rate can be increased.
