[0058] Air conditioners are commonly used indoor temperature and humidity control devices that can blow cool or hot air into the room as needed.

[0059] Since hot air is lighter than cold air and therefore occupies a higher position, when an air conditioner is in heating mode, the hot air blown from above will remain at a higher position in the room, hindering its even mixing with the cold air at a lower position. This results in a slower rate of temperature increase and a poor user experience. Furthermore, increased carbon dioxide concentration due to human activity, coupled with inadequate or improperly positioned ventilation, can also reduce comfort.

[0060] Existing technologies employ reversible air conditioning, featuring two air vents, one above and one below, with dual fans operating to allow the air conditioner to either vent at the upper vent or at the lower vent with a single fan. However, this type of reversible duct with dual fans suffers from significant airflow loss, low air pressure, and poor single-fan air delivery capacity due to its long duct openings. Consequently, the airflow is small, the delivery distance is short, and the cooling or heating performance is affected, impacting the user experience.

[0061] Example 1

[0062] Based on this, such as Figures 1-7 As shown, the air duct assembly according to an embodiment of the present invention includes: an air duct housing, the air duct housing including a first air duct unit and a second air duct unit disposed vertically.

The air outlets of the first main air duct 31 and the first secondary air duct 32 are connected together.

[0064] The second air duct unit includes a second main air duct 33 and a second auxiliary air duct 34. The second main air duct 33 is equipped with a second main fan 6, and the second auxiliary air duct 34 is equipped with a second auxiliary fan 7. The air outlets of the second main air duct 33 and the second auxiliary air duct 34 are connected together.

[0065] The first main air duct 31 has a first connecting port on the side facing away from the first main fan 4, the second main air duct 33 has a second connecting port on the side facing away from the second main fan 6, the first auxiliary air duct 32 has a third connecting port on the side facing away from the first main air duct 31, and the second auxiliary air duct 34 has a fourth connecting port on the side facing away from the second main air duct 33.

The first air control member can be controlled to close the first communication port at the same time to make the top of the third sub-air duct 35 communicate with the outside of the air duct shell, or open the first communication port at the same time to make the top of the third sub-air duct 35 separate from the outside of the air duct shell. The second air control member can be controlled to close the second communication port at the same time to make the bottom of the third sub-air duct 35 communicate with the outside of the air duct shell, or open the second communication port at the same time to make the bottom of the third sub-air duct 35 separate from the outside of the air duct shell. The third air control member can be controlled to open the third communication port at the same time to make the first main fan 4 and the first sub-fan 5 both separate from the first main air duct 31, or close the third communication port at the same time to make the outflow side of the first main fan 4 and the first sub-fan 5 communicate with the first main air duct 31. The fourth air control member can be controlled to open the fourth communication port at the same time to make the second main fan 6 and the second sub-fan 7 both separate from the second main air duct 33, or close the third communication port at the same time to make the outflow side of the second main fan 6 communicate with the second main air duct 33.

[0067] The air duct assembly is provided with a first air duct unit, a second air duct unit and the third sub-air duct 35. The first air duct unit communicates the containing cavity 101 and the first air outlet 102. The second air duct unit communicates the containing cavity 101 and the second air outlet 103. The third sub-air duct 35 can switch to communicate the first air outlet 102 and the containing cavity 101 or communicate the second air outlet 103 and the containing cavity 101. When single-out air is needed, the third sub-air duct 35 can be communicated with the corresponding single-out air outlet to increase the air volume of single-out air, thereby achieving the technical effect of enhancing the air volume of single-out air.

The air taken in through the third air outlet 104 and the fourth air outlet 105 directly enters the containing cavity 101 and exchanges heat with the heat exchange assembly 2. The air taken in through the second air outlet 103 enters the containing cavity 101 through the second air duct unit and exchanges heat with the heat exchange assembly 2. The cold air after heat exchange enters the first air duct unit and the third sub-air duct 35 and is exhausted through the first air duct unit and the third sub-air duct 35 at the same time.

[0069] When heating is needed, air can be taken in through the third air inlet 104, the fourth air inlet 105, and the first air inlet 102. The air taken in through the third air inlet 104 and the fourth air inlet 105 directly enters the containing cavity 101 and exchanges heat with the heat exchange assembly 2. The air taken in through the first air inlet 102 enters the containing cavity 101 through the first air duct unit and exchanges heat with the heat exchange assembly 2. The hot air after heat exchange enters the second air duct unit and the third auxiliary air duct 35 and is exhausted through the second air duct unit and the third auxiliary air duct 35.

[0070] When air is exhausted through a single air inlet, i.e. cold air or hot air is exhausted through the first air inlet 102 or the second air inlet 103, not only can the cold air or hot air be exhausted through the first air duct unit or the second air duct unit, but also the air exhaust volume can be increased through the third auxiliary air duct 35, which can effectively improve the refrigeration or heating effect.
