[0056] By controlling the opening and closing of the first fan 500, the first sub-fan 410, the second sub-fan 420, the first opening and closing member, and the second opening and closing member, air outlet modes in various cooling modes can be realized, and several typical air outlet modes are further explained below.

[0057] 1. Centrifugal air outlet mode

[0058] The first sub-fan 410 and the second sub-fan 420 are turned on, and the first air duct 221 and the second air duct 231 are turned off. The first sub-fan 410 causes the indoor air near the first sub-air inlet 1121 to enter between the front air duct member 100 and the rear air duct member 200 to be heat exchanged by the heat exchanger 300, and the heat exchanged air flows to the first sub-air duct 1131, the first gap and the second gap in sequence and flows to the indoor environment, and the second sub-fan 420 causes the indoor air near the second sub-air inlet 1122 to enter between the front air duct member 100 and the rear air duct member 200 to be cooled by the heat exchanger 300, and then causes the cooled air to flow to the second sub-air duct 1132, the first gap and the second gap in sequence and flow to the indoor environment.

[0059] In this mode, one of the first sub-blower 410 and the second sub-blower 420 may be selected to be turned on.

[0060] In this mode, the air outlet temperature of the air duct assembly 10 is low.

[0061] 2. Jet uniform wind mode

[0062] The first sub-blower 410 and the second sub-blower 420 are turned on, the first air duct 221 and the second air duct 231 are connected, and the second blower 400 is turned off.

[0063] The first sub-fan 410 causes the air after heat exchange by the heat exchanger 300 to flow to the first sub-duct 1131, the first air outlet gap 1111 and the second air outlet gap 1112 in sequence. The second sub-fan 420 causes the air after cooling by the heat exchanger 300 to flow to the second sub-duct 1132, the first air outlet gap 1111 and the second air outlet gap 1112 in sequence. In addition, the indoor air flowing out through the first air duct 221 and the second air duct 231 and the air flowing out through the first air outlet gap 1111 and the second air outlet gap 1112 are mixed and flow to the indoor environment together.

[0064] In this mode, one of the first sub-blower 410 and the second sub-blower 420 may be turned on to connect one of the first air duct 221 and the second air duct 231 .

[0065] The air outlet of the air duct assembly 10 in this mode is mixed with a certain amount of indoor air, so compared with the centrifugal air outlet mode, the air outlet temperature is higher and softer.

[0066] 3. Mixed air outlet mode

[0067] The first fan 500, the first sub-fan 410 and the second sub-fan 420 are turned on, and the first air duct 221 and the second air duct 231 are connected. Compared with the jet uniform wind mode, the first fan 500 can make the air output of the air duct assembly 10 have a higher indoor air content and a softer air output.

[0068] In this mode, one of the first sub-blower 410 and the second sub-blower 420 may be turned on and the second air duct 231 may be turned off.

[0069] The mixed air has a large indoor air content, the air outlet temperature of the air duct component 10 is the highest, and the air outlet is the softest.

[0070] In addition, by controlling the opening and closing of the three fans, the opening and closing of the first air duct 221 and the second air duct 231 can also achieve a variety of air outlet modes to meet the soft wind comfort requirements of different users, which are not listed here one by one.

[0071] Figure 5 is a schematic structural block diagram of a vertical air conditioner 1 according to an embodiment of the present invention. Figure 5 As shown, based on the same inventive concept, the present invention further proposes a vertical air conditioner 1, and the vertical air conditioner 11 includes an air duct assembly 10 as in any of the above embodiments.

[0072] The air duct assembly 10 provided by the present invention includes a rear air duct member 200, which includes a substrate 210 and a first air duct member 220 fixedly arranged on the front side of the substrate 210. The first air duct member 220 defines a first air duct 221 whose two ends are connected to the indoor environment. Therefore, in the cooling mode, the air output of the air duct assembly 10 contains indoor air, the air output of the air duct assembly 10 is soft and the air output volume is large, the cooling speed is not reduced, and the user experience is improved.

[0073] Furthermore, the air duct assembly 10 also includes a first fan 500 arranged at the inlet of the first air duct 221. The first fan 500 is configured to cause the indoor air near the inlet of the first air duct 221 to flow to the outlet of the first air duct 221. In the cooling mode, the indoor air content in the mixed air outlet is increased, the air outlet temperature and air volume of the air duct assembly 10 are further increased, and the user experience is further improved.
