In order to facilitate processing and assembly, the casing is usually set in two halves, such as a front casing and a rear casing. shell. The air duct structure is an important part of the vertical air conditioner. It is not only used to provide air ducts for the airflow in the vertical air conditioner, but also used to install the transmission mechanism, impeller, heat exchanger and other components of the sweeping blades. The air duct structure is fixedly connected, so the air duct structure is relatively complex, and the mold design and production costs are also high. In the related art, referring to FIGS. 1 to 3 , FIG. 1 is an exploded view of the overall skeleton and the rear shell 21 of the neutral air conditioner in the related art, and FIGS. 2 and 3 are respectively the air duct structure 10 in FIG. 21 Schematic diagram of the structure of the junction.

The inner side of the rear shell of the type air conditioner forms a rear shell assembly with the rear shell, and the rear shell assembly is integrally fixed with the air duct structure. Due to the introduction of the air pretreatment device, the shape of the rear shell will change as a whole. In order to accommodate the air pretreatment device, the size of the rear shell in the front and rear directions will be increased. The air duct structure is matched, and the structural reliability is difficult to guarantee, and screws are usually used for fixing here, which will cause the screw length to be too long and difficult to assemble; and if the air duct structure is changed to adapt to the shape of the rear shell, the air duct structure needs to be redesigned. It brings about a substantial increase in cost and a reduction in development efficiency.

Based on this, an embodiment of the present application provides a vertical air conditioner structure with an air conditioner pretreatment device.
