The air duct shell 2 of the embodiment includes an air duct rear shell 21 and an air duct front shell 22, the air duct rear shell 21 is connected with the air duct front shell 22, and an air duct 20 is formed between the air duct front shell 22 and the air duct rear shell 21; the fan assembly 4 includes a centrifugal fan 41, the rear air inlet 211 includes a first air inlet 211a disposed on the air duct rear casing 21, the air duct 20 includes a first air duct 201 formed between the first air inlet 211a and the front air outlet 221, the lower end of the top air outlet frame 3 is communicated with the first air duct 201, and the centrifugal fan 41 is disposed in the first air duct 201. The fan assembly 4 further includes an axial flow fan 42, the rear air inlet 211 further includes a second air inlet 211b disposed on the air duct rear shell 21, the second air inlet 211b is located above the first air inlet 211a, the front air outlet 221 is disposed corresponding to the second air inlet 211b, the air duct 20 further includes a second air duct 202 formed between the second air inlet 211b and the front air outlet 221, and the axial flow fan 42 is disposed in the second air duct 202.
Specifically, the air duct rear shell 21 of the embodiment has a first air inlet 211a near the bottom, a second air inlet 211b near the top, and a front air outlet 221 near the top of the air duct front shell 22, where the front air outlet 221 and the second air inlet 211b are arranged opposite to each other. The centrifugal fan 41 is located below the axial fan 42, and the air supply principle of the axial fan 42 is axial air inlet and radial air outlet, so that when the centrifugal fan 41 works, the centrifugal fan 41 can guide air flow to enter the first air duct 201 from the first air inlet 211a, and the air flow moves upward along the first air duct 201 and is blown out to the front side through the front air outlet 221. The air supply of the axial flow fan 42 is far from the axial air supply and axial air discharge, so that when the axial flow fan 42 operates, the axial flow fan 42 can guide the air flow to enter the second air duct 202 from the second air inlet 211b and blow out to the front side through the front air outlet 221. The dashed arrows in fig. 5 to 7 indicate the flow direction of the air flow.
It should be noted that, in an embodiment, when the temperature difference between the indoor ambient temperature and the desired temperature required by the user is small, the centrifugal fan 41 or the axial fan 42 may be selected to work alone, that is, only the centrifugal fan 41 participates in the air supply, or only the axial fan 42 participates in the air supply. In another embodiment, when the temperature difference between the indoor ambient temperature and the ideal temperature required by the user is large, the centrifugal fan 41 and the axial flow fan 42 can be selected to work simultaneously, that is, the centrifugal fan 41 and the axial flow fan 42 can participate in air supply simultaneously, the air inlet area is increased, the air supply distance is far away, the air supply range is enlarged, the heat exchange efficiency is improved, and the comfort is improved. In addition, in this embodiment, the double-air-duct 20 air supply mode through the first air duct 201 and the second air duct 202 increases the air inlet area compared with the single-air-duct air supply mode, so that the inlet airflow is uniform, the heat exchange of the heat exchanger is uniform, the heat exchange efficiency is improved, the system energy efficiency is improved, and compared with the single-air-duct 20 air supply mode under the same air volume, the noise of the double-air-duct 20 air supply mode is also reduced to some extent, and the noise pollution is reduced. The centrifugal fan 41 or the axial flow fan 42 can be selected to work independently or the centrifugal fan 41 or the axial flow fan 42 can be selected to work simultaneously according to the actual requirements of users.
In this embodiment, the guide shell 23 is installed at the second air inlet 211b, the guide shell 23 extends toward the front air outlet 221, and the axial flow fan 42 is installed in the guide shell 23. The area of the front air outlet 221 is larger than that of the front port of the guide cylinder 23. As shown in fig. 4 to 6, the guide cylinder 23 of this embodiment is in a horn shape, a rear port of the guide cylinder 23 is connected to an edge position of the second air inlet 211b, a front port of the guide cylinder 23 extends to one side of the front air outlet 221, and an inner cylinder diameter of the guide cylinder 23 is arranged to decrease from back to front, an axis of the axial flow fan 42 and an axis of the guide cylinder 23 are located on the same straight line, and air sucked into the second air duct 202 from the second air inlet 211b can be gradually concentrated toward an axial direction of the axial flow fan 42 along the guide cylinder 23, so that the axial flow fan 42 supplies air, and an area of the front air outlet 221 is larger than an area of the front port of the guide cylinder 23, which is beneficial to expanding an air supply range.
Furthermore, the guide cylinder 23 is integrally formed on the air duct rear shell 21, so that the air duct rear shell is convenient to manufacture, assembly gaps and errors are omitted, and the structural stability is good. A gap is formed between the outer wall of the guide cylinder 23 and the inner side wall of the air duct rear shell 21, and the lower end of the top air outlet frame 3 is communicated with the first air duct 201 through the gap. When entering the top air-out mode, the centrifugal fan 41 works, and the airflow in the first air duct 201 is blown upwards into the top air-out frame 3 through the gap, so that the top air outlet 31 supplies air. When the floor type air-conditioning indoor unit 100 exits the top air-out mode, the centrifugal fan 41 works, negative pressure can be formed in the first air duct 201 when air flow passes through the gap, and an air flow circulating towards the front air outlet 221 can be formed in the first air duct 201 under the action of the negative pressure, so that the air outlet quantity of the floor type air-conditioning indoor unit 100 can be increased, the air supply distance is increased, and the heat exchange efficiency of the floor type air-conditioning indoor unit 100 is improved.
As shown in fig. 5 and 6, vertical cut edges 231 are disposed on both sides of the outer wall of the guide cylinder 23, and the vertical cut edges 231 are disposed in parallel with the inner side wall of the air duct rear shell 21. The vertical trimming 231 increases the gap width, so that the air flow in the first air duct 201 is large and smoothly enters the top air outlet frame 3 through the gap, the air outlet amount of the top air outlet 31 is increased, and the effectiveness of the top air outlet mode is improved.
In this embodiment, a stationary blade 5 is disposed in the second air duct 202, the stationary blade 5 is disposed opposite to the axial flow fan 42, and the axial flow fan 42 is located between the second air inlet 211b and the stationary blade 5. The stationary blade 5 can reintegrate the airflow, so that the air outlet of the axial flow fan 42 is more uniform and the noise is lower.
In this embodiment, a front air-out frame 24 is disposed at a position of the air duct front shell 22 corresponding to the axial flow fan 42, and the front air-out frame 24 forms a front air outlet 221. Display lamp area 6 is installed to the front side of preceding air-out frame 24, and display lamp area 6 corresponds preceding air outlet 221 and sets up. The display lamp strip 6 of the present embodiment has a prompting function, for example, when cold air is blown out from the front air outlet 221, the display lamp strip 6 is blue, which indicates that the floor type air conditioning indoor unit 100 is currently in the cooling mode; when hot air is blown out from the front air outlet 221, the display lamp strip 6 turns red, which indicates that the floor type air conditioning indoor unit 100 is currently in the heating mode.
