For example, when the air conditioner indoor unit 1 is a floor air conditioner indoor unit, the size of the air conditioner indoor unit 1 in the height direction is large, and the cross-sectional areas of the first side duct opening 420 and the second side duct opening 430 are the largest, so that the size of the air conditioner in the height direction is more suitable, the uniform air outlet effect is achieved, and the arrangement of the air duct assembly 400 is reasonable. The first side air duct opening 420 and the second side air duct opening 430 are symmetrically arranged, and the first lower air duct opening 440 and the second lower air duct opening 450 are symmetrically arranged, so that the air outlet heights of the first side air duct opening 420 and the second side air duct opening 430 are the same, and the air outlet on the two sides of the shell 100 is uniform. The first lower duct opening 440 and the second lower duct opening 450 have the same air outlet height, and air can be exhausted from both the left and right sides of the front wall of the casing 100.
Specifically, the ratio of the cross-sectional area of the first side duct port 420, the cross-sectional area of the first lower duct port 440, and the cross-sectional area of the fresh air guide port 411 is 1: (0.83-0.9): (0.81-0.92). The ratio of the cross-sectional area of the second side air duct opening 430, the cross-sectional area of the second lower air duct opening 450 and the cross-sectional area of the fresh air guide opening 411 is 1: (0.83-0.9): (0.81-0.92).

Meanwhile, the fresh air guide opening 411 does not occupy the air outlet areas of the first lower air duct opening 440 and the second lower air duct opening 450, and the arrangement of the air outlet area of the air duct assembly is more reasonable.
In some embodiments of the present invention, as shown in fig. 3, the front side of the air duct assembly 400 is configured with a first air duct rib 412 and a second air duct rib 413, and the air duct assembly 400 forms the air mixing channel 410 together with the casing 100 through the first air duct rib 412 and the second air duct rib 413.
The first air duct ribs 412 and the second air duct ribs 413 protrude from the front side wall of the air duct assembly 400, the air duct assembly 400 surrounds the closed air mixing channel 410 through the first air duct ribs 412, the second air duct ribs 413 and the casing 100, for example, the cross section of the air mixing channel 410 is rectangular. At this time, the air mixing channel 410 is located at the front sides of the first side air duct opening 420 and the second side air duct opening 430, and the air mixing channel 410 does not occupy the air guiding space inside the air duct assembly 400, so that the air outlet areas of the first side air outlet 120, the second side air outlet 130, the first lower air outlet 140 and the second lower air outlet 150 are not affected, and the space utilization rate inside the casing 100 is higher.
Further, as shown in fig. 4, each of the first air duct rib 412 and the second air duct rib 413 includes a vertical section 414 and an inclined section 415 connected below the vertical section 414, the vertical section 414 of the first air duct rib 412 and the vertical section 414 of the second air duct rib 413 are parallel to each other, the first lower air outlet 140 and the second lower air outlet 150 are located below the vertical section 414 of the first air duct rib 412 and the vertical section 414 of the second air duct rib 413, and a distance between the inclined section 415 of the first air duct rib 412 and the inclined section 415 of the second air duct rib 413 is gradually increased from bottom to top.
For example, the first air channel rib 412 and the second air channel rib 413 are symmetrically arranged, and after the airflow of the fresh air assembly 300 enters the air mixing channel 410 from the fresh air guide opening 411, the width of the air mixing channel 410 gradually increases, and the size in the thickness direction of the air mixing channel 410 gradually decreases, so that the relative change of the cross-sectional area is kept small. And a first lower air duct opening 440 and a second lower air duct opening 450 are formed at two sides of the first air duct rib 412 and the second air duct rib 413, and the distance below the first air duct rib 412 and the second air duct rib 413 is smaller, so that the first lower air outlet 140 and the second lower air outlet 150 keep larger cross-sectional areas.
In some embodiments of the present invention, as shown in fig. 1, the front wall of the casing 100 is provided with an air outlet groove 160 recessed towards the inside, the first lower air outlet 140 and the second lower air outlet 150 are provided on the top wall of the air outlet groove 160, and the bottom wall of the air outlet groove 160 extends obliquely from top to bottom.

And the bottom wall of the air outlet groove 160 extends obliquely from top to bottom, so that the air flow of the first lower air outlet 140 and the second lower air outlet 150 can smoothly guide to the ground along the bottom wall of the air outlet groove 160, and the air outlet is smoother.
In some embodiments of the present invention, as shown in fig. 2, the air conditioner indoor unit 1 further includes a guide ring 500.
The deflector ring 500 surrounds the positive air outlet 110 and is communicated with both the air mixing channel 410 and the positive air outlet 110, and the diameter of the outer circumferential surface of the deflector ring 500 surrounding the positive air outlet 110 is gradually reduced toward the positive air outlet 110.
For example, the flow guide ring 500 is composed of two layers of structures, i.e., an inner layer and an outer layer, along the radial direction, an annular air guide area is formed between the outer ring and the inner ring of the flow guide ring 500, and the outer circumference of the inner ring of the flow guide ring 500 is inclined towards the air outlet direction, so that the air flow in the annular air guide area can flow towards the central area of the positive air outlet 110, and then is mixed with the air conditioning air flowing out of the positive air outlet 110 and then is conveyed indoors, so that the large air volume is realized, and the air conditioning air is mixed with outdoor fresh air, so that the indoor air quality is improved.
In some embodiments of the present invention, as shown in fig. 2, an axial flow air duct 460 and a centrifugal air duct (not shown) are defined inside the air duct assembly 400, an axial flow fan 461 is disposed in the axial flow air duct 460, a centrifugal fan 471 is disposed in the centrifugal air duct, the axial flow air duct 460 is communicated with the front air outlet 110, and the centrifugal air duct is communicated with the first side air outlet 120, the second side air outlet 130, the first lower air outlet 140, and the second lower air outlet 150.
Specifically, the axial flow duct 460 is located above the centrifugal duct, the front air outlet 110 is aligned with the axial direction of the axial flow fan 461, and the axial flow fan 461 is arranged in the axial flow duct 460, so that the axial flow fan 461 guides air to achieve a stronger airflow along the axial direction.
By arranging the centrifugal fan 471 in the centrifugal air duct, the airflow generated by the centrifugal fan 471 flows out from the first side air outlet 120 through the first side air duct opening 420, flows out from the second side air outlet 130 through the second side air duct opening 430, flows out from the first lower air outlet 140 through the first lower air duct opening 440, and flows out from the second lower air outlet 150 through the second lower air duct opening 450. The first side air duct opening 420 and the second side air duct opening 430 are respectively located at two sides of a radial path of the centrifugal fan 471, and the first lower air duct opening 440 and the second lower air duct opening 450 are located below the centrifugal fan 471.

The fresh air assembly 300 includes a fresh air blower 310, and the rotation axis of the fresh air blower 310 is perpendicular to the rotation axis of the axial flow fan 461 and the rotation axis of the centrifugal fan 471.
For example, the centrifugal fan 471 may be a backward centrifugal fan, the fresh air fan 310 may be a forward centrifugal fan, and the fresh air fan 310 introduces fresh air from an axial direction thereof and then guides the fresh air to the air mixing channel 410.

Moreover, the rotation axes of the axial flow fan 461 and the centrifugal fan 471 are parallel to each other, so that the centrifugal fan 471 discharges air to both sides and below in the radial direction while the axial flow fan 461 discharges air to the front side, which is beneficial to the arrangement of the air duct assembly 400. The rotation axis of the fresh air blower 310 is perpendicular to the rotation axis of the axial flow blower 461 and the rotation axis of the centrifugal blower 471, so that the air outlet direction of the fresh air assembly 300 is adapted to the air mixing channel 410.
In some embodiments of the present invention, as shown in fig. 2, there are two centrifugal fans 471, the two centrifugal fans 471 are arranged in a vertical direction, the centrifugal fan 471 located above is communicated with the first side air outlet 120 and the second side air outlet 130, and the centrifugal fan 471 located below is communicated with the first side air outlet 120, the second side air outlet 130, the first lower air outlet 140 and the second lower air outlet 150.
