In other embodiments, the lower air outlet assembly 150 may not be provided, and the third fan 132 may be disposed close to the lower air outlet 1122.
The air conditioning indoor unit 100 provided in this embodiment has the following beneficial effects:
the air outlet of the first fan 121 and the air outlet of the second fan 122 are respectively blown out from the two upper air outlets 1121 through the two independent upper air outlet channels 142, so that the air outlet directions of the two upper air outlets 1121 can be respectively controlled, for example, the two air outlets can blow air towards two sides, and people can be prevented from being directly blown out. When cooling (fig. 3), the upper air duct assembly 120 is started and the lower air duct assembly 130 is closed, and at this time, the housing air inlet 115 and the lower air outlet 1122 can simultaneously supply air, so as to increase the air inlet amount of the upper air duct assembly 120; and the upper air outlet 1121 discharges cold air to enable the cold air to fall in a waterfall manner from top to bottom, so that the user experience is improved. When heating (fig. 4), the upper duct assembly 120 and the lower duct assembly 130 can be opened simultaneously, and hot air can quickly fall to the ground after being blown out from the lower outlet 1122 to realize carpet heating. In addition, the upper duct assembly 120 and the lower duct assembly 130 share the heat exchanger 160 and the air inlet grill (not shown), which enables the overall size of the indoor unit 100 to be reduced.
Example 2:
the present embodiment provides an air conditioner indoor unit control method, which can be used to control the air conditioner indoor unit 100 provided in embodiment 1, and specifically includes:
when heating is needed, the upper air duct assembly 120 and the lower air duct assembly 130 are started, so that the upper air outlet 1121 and the lower air outlet 1122 simultaneously discharge air; because the density of hot air is relatively low, hot air has a tendency of flowing upwards, the hot air at the upper air outlet 1121 mainly heats the upper area, the lower air outlet 1122 directly realizes carpet heating below, and the hot air can rapidly heat different indoor areas along with the upward flowing of the air outlet of the lower air outlet 1122.
When refrigeration is needed, the upper air duct assembly 120 is started and the lower air duct assembly 130 is closed, so that air is discharged from the upper air outlet 1121; at this time, the lower air outlet 1122 and the air inlet on the rear panel 114 can both supply air to the upper air duct assembly 120, so as to increase the air intake of the upper air duct assembly 120. The cold air has the tendency of flowing downwards due to the fact that the density of the cold air is increased; during refrigeration, the comfort can be obviously improved by bath type refrigeration from top to bottom.
In other embodiments, when heating, only the lower air duct assembly 130 may be turned on, and at this time, the upper air outlet 1121 may also supply air to the lower air duct assembly 130.
Although the present invention is disclosed above, the present invention is not limited thereto. Various modifications may be made by those skilled in the art without departing from the spirit and scope of the invention, and such modifications are intended to be within the scope of the invention.
