When cooling ( FIG. 3 ), the upper air duct assembly 120 is activated and the lower air duct assembly 130 is closed. At this time, the housing air inlet 115 and the lower air outlet 1122 can enter air at the same time, thereby increasing the air intake volume of the upper air duct assembly 120; The cool air from the air outlet 1121 can make the cool air fall from top to bottom in a waterfall manner, thereby improving user experience. When heating ( FIG. 4 ), the upper air duct assembly 120 and the lower air duct assembly 130 can be opened at the same time, and the hot air can be quickly blown out from the lower air outlet 1122 to achieve carpet heating. In addition, the upper air duct assembly 120 and the lower air duct assembly 130 share a heat exchanger 160 and an air intake grille (not shown in the figure), which can reduce the overall size of the air conditioner indoor unit 100 .

Example 2:

This embodiment provides a method for controlling an air conditioner indoor unit, which can be used to control the air conditioner indoor unit 100 provided in Embodiment 1, specifically:

When heating is required, the upper air duct assembly 120 and the lower air duct assembly 130 are activated, so that the upper air outlet 1121 and the lower air outlet 1122 discharge air at the same time; due to the relatively low density of hot air, the hot air has a tendency to flow upward, and the upper air outlet 1121 has a tendency to flow upward. The hot air mainly heats the upper area, and the lower air outlet 1122 directly realizes carpet heating below, and as the air out of the lower air outlet 1122 flows upward, the hot air can rapidly heat different areas in the room.

When cooling is required, the upper air duct assembly 120 is activated and the lower air duct assembly 130 is closed, so that the upper air outlet 1121 discharges air; at this time, both the lower air outlet 1122 and the air inlet on the rear panel 114 can supply air to the upper air duct assembly 120, Thus, the air intake volume of the upper air duct assembly 120 is increased. Due to the increased density of cold air itself, it has a tendency to flow downward; when cooling, top-down bath cooling can significantly improve comfort.

In other embodiments, when heating, only the lower air duct assembly 130 may be opened, and at this time, the upper air outlet 1121 can also supply air to the lower air duct assembly 130 .

Although the present invention is disclosed above, the present invention is not limited thereto. Any person skilled in the art can make various modifications without departing from the spirit and scope of the present invention, and the above modifications are all within the protection scope of the present invention.
