[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 achieved. 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 forces the indoor air near the first sub-inlet 1121 to enter between the front duct member 100 and the rear duct member 200 for heat exchange by the heat exchanger 300. The heat-exchanged air then flows sequentially through the first sub-duct 1131, the first gap, and the second gap, and finally into the indoor environment. The second sub-fan 420 forces the indoor air near the second sub-inlet 1122 to enter between the front duct member 100 and the rear duct member 200 for cooling by the heat exchanger 300. The cooled air then flows sequentially through the second sub-duct 1132, the first gap, and the second gap, and finally into 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 of 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 conducted. Compared with the jet flow uniform air mode, the first fan 500 is turned on to make the indoor air content in the air outlet of the air duct assembly 10 higher, and the air outlet softer.

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

[0069] The indoor air content in the air outlet is large, the air outlet temperature of the air duct assembly 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 on-off of the first air duct 221 and the second air duct 231 can also realize multiple air outlet modes to meet the requirements of different users for soft air comfort, which will not be listed one by one here.

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

[0072] The air duct assembly 10 provided by the present application includes a rear air duct piece 200, which includes a base plate 210 and a first air duct piece 220 fixedly arranged on the front side of the base plate 210. The first air duct piece 220 defines a first air duct 221 having two ends communicated with the indoor environment, so that in the cooling mode, the air outlet of the air duct assembly 10 contains indoor air, the air outlet of the air duct assembly 10 is soft and the air outlet volume is large, the cooling speed is not reduced, and the user experience is improved.

[0073] Further, the air duct assembly 10 further includes a first fan 500 arranged at the inlet of the first air duct 221, which is configured to promote 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 improved, the air outlet temperature and the air outlet volume of the air duct assembly 10 are further improved, and the user experience is further improved.
