[0032] This disclosure provides an indoor unit for a cabinet-type air conditioner.

[0033] Optionally, the indoor unit of the cabinet air conditioner includes a housing 1, an air duct assembly, and a fresh air assembly. The housing 1 has a first air outlet 101 and a second air outlet 102; the air duct assembly is disposed inside the housing 1 and includes a first fan 2 and a first air duct section 21 connecting the first fan 2 with the first air outlet 101 and the second air outlet 102; the fresh air assembly includes a fresh air fan 3, which has a fresh air outlet 31. The fresh air fan 3 is rotatably disposed between the first air outlet 101 and the second air outlet 102, so that the fresh air delivered from the fresh air outlet 31 can selectively mix with the air supplied from the first air outlet 101 or the second air outlet 102.

[0034] The indoor unit of the cabinet air conditioner also includes a heat exchanger installed inside the casing 1, which is located in the first air duct section 21. In this way, the indoor return air enters through the air inlet of the casing 1, exchanges heat with the heat exchanger, and is then sent out from the first air outlet 101 and the second air outlet 102.

[0035] The fresh air assembly includes a fresh air fan 3, which is positioned between a first air outlet 101 and a second air outlet 102. The fresh air fan 3 is rotatable to adjust the orientation of the fresh air outlet 31. The fresh air outlet 31 can selectively face either the first air outlet 101 or the second air outlet 102. When the fresh air outlet 31 faces the first air outlet 101, the fresh air from the fresh air fan 3 mixes with the heat exchange air from the first air outlet 101 and is then delivered to the user. Figure 11 As shown; when the fresh air outlet 31 faces the second air outlet 102, the fresh air from the fresh air fan 3 mixes with the heat exchange air from the second air outlet 102 and is then delivered to the user, as... Figure 12 As shown; optionally, the fresh air outlet 31 of the fresh air fan 3 can also face forward, so that heat exchange air and fresh air are delivered separately, such as Figure 10 As shown.

[0036] Optionally, the first fan 2 for supplying heat exchange air includes a vertically arranged first cross-flow fan; the fresh air fan 3 includes a vertically arranged second cross-flow fan. Optionally, the diameter of the first cross-flow fan is R1, and the diameter of the second cross-flow fan is R2, wherein 0.3R1≤R2<R1. In this way, while ensuring the intensity of the heat exchange air supplied from the first air outlet 101 and the second air outlet 102, the effect of supplying fresh air by the fresh air fan 3 is improved.

[0037] Optionally, both the first air outlet 101 and the second air outlet 102 are vertically oriented, and the fresh air outlet 31 is also vertically oriented and located between the first air outlet 101 and the second air outlet 102. Optionally, the height of both the first air outlet 101 and the second air outlet 102 is H1, and the height of the fresh air outlet 31 is H2, wherein 0.8H1≤H2

[0038] Optionally, the first air outlet 101 includes a lowermost first air outlet bottom end and a highermost first air outlet top end; the second air outlet 102 includes a lowermost second air outlet bottom end and a highermost second air outlet top end; and the fresh air outlet 31 includes a lowermost fresh air outlet bottom end and a highermost fresh air outlet top end. The lower ends of the first and second air outlets are approximately flush with the lower end of the fresh air outlet, roughly on the same horizontal plane, while the uppermost and lower ends of the first and second air outlets are both slightly higher than the uppermost fresh air outlet top end. Figure 1 As shown. The air delivered from the first air outlet 101 and the second air outlet 102 is heat exchange air. When the air conditioner is running in cooling mode, the cold air has a sinking effect. In this embodiment, the fresh air outlet 31 is slightly lower than the first air outlet 101 and the second air outlet 102, which helps to improve the mixing effect of fresh air and heat exchange air.

[0039] Optionally, the second cross-flow fan includes a fresh air unit housing 301 and cross-flow fan blades disposed within the fresh air unit housing 301. A fresh air outlet 31 is opened in the fresh air unit housing 301. The fresh air assembly also includes a drive assembly 4, which is drivenly connected to the fresh air unit housing 301 to drive the fresh air unit housing 301 to rotate and adjust the direction of the fresh air outlet 31. The fresh air unit housing 301 includes a first air duct plate 32 and a second air duct plate 33. The inner surface of the first air duct plate 32 is arc-shaped, including a first pointed end 321 and a first flat end 322. The inner surface of the second air duct plate 33 is arc-shaped, including a second pointed end 331 and a second flat end 332. The first air duct plate 32 and the second air duct plate 33 form a fresh air outlet duct, wherein the fresh air outlet 31 is disposed between the first pointed end 321 and the second flat end 332.

[0040] The drive component 4 drives the fresh air unit housing 301 to rotate, thereby adjusting the direction of the fresh air outlet 31. The fresh air unit housing 301 includes a first air duct plate 32 and a second air duct plate 33, which together form a fresh air outlet duct for delivering fresh air.

[0041] ​The outer surface of the first air duct plate 32 is partially arc-shaped, and the outer surface of the second air duct plate 33 is also partially arc-shaped. The inner surface of the first air duct plate 32 is arc-shaped, and the two ends of the first air duct plate 32 have different widths, with the narrower end being the first pointed end 321 and the wider end being the first flat end 322. Similarly, the inner surface of the second air duct plate 33 is also arc-shaped, and the two ends of the second air duct plate 33 have different widths, with the narrower end being the second pointed end 331 and the wider end being the second flat end 332.

[0042] Optionally, the first air duct plate 32 is located near the first air outlet 101, and the second air duct plate 33 is located near the second air outlet 102. This can be understood as follows: when the fresh air outlet 31 sends air forward, the first air duct plate 32 is positioned near the first air outlet 101, and the second air duct plate 33 is positioned near the second air outlet 102. Figure 10 As shown. Optionally, the extension length of the first air duct plate 32 is greater than the extension length of the second air outlet plate. In this embodiment of the present disclosure, the fresh air outlet 31 is disposed between the first tip 321 and the second flat end 332, which is beneficial to improving the air outlet effect of the second cross-flow fan.

[0043] Optionally, the top 3011 of the fresh air unit housing 301 is provided with a protrusion, wherein the protrusion is provided with a rack portion, and the drive assembly 4 includes a drive motor and a gear, the gear meshing with the rack portion.

[0044] The drive motor drives the gear to rotate, and the gear meshes with the rack portion of the protrusion on the top 3011 of the fresh air unit housing 301, thereby rotating the fresh air unit housing 301 and adjusting the air outlet direction of the fresh air outlet 31. Optionally, the protrusion is circular, and a rack portion is provided on the outer periphery of the protrusion. Optionally, the top 3011 of the fresh air unit housing 301 is provided with a first protrusion 3021, and the bottom of the fresh air unit housing 301 is provided with a second protrusion 3022. Both the first protrusion 3021 and the second protrusion 3022 are provided with rack portions and are driven to rotate by the drive assembly 4, thus improving the rotational stability of the fresh air unit housing 301. Figure 3 As shown.

[0045] Optionally, the first air duct plate 32 and the second air duct plate 33 are connected to the top 3011 of the fresh air unit housing 301 so that the drive assembly 4 drives the first air duct plate 32 and the second air duct plate 33 to rotate, thereby adjusting the direction of the fresh air outlet 31.

[0046] It is understood that the top 3011 of the fresh air unit housing 301 is a portion of the top of the fresh air unit housing 301, and the first air duct plate 32 and the second air duct plate 33 are portions of the fresh air unit housing 301 located on the side. The first air duct plate 32, the second air duct plate 33 and the top 3011 of the fresh air unit housing 301 are integrally formed.

[0047] Optionally, the housing 1 includes a front housing portion 11, a first side housing portion 12, and a second side housing portion 13. The first air outlet 101 includes a first front air outlet 1011 opened in the front housing portion 11 and a first side air outlet 1012 opened in the first side housing portion 12. The second air outlet 102 includes a second front air outlet 1021 opened in the front housing portion 11 and a second side air outlet 1022 opened in the second side housing portion 13. The fresh air unit housing 301 includes a protruding housing portion 303 protruding from the first front air outlet 1011 and the second front air outlet 1021, and a fresh air outlet 31 is disposed on the protruding housing portion 303.

[0048] The fresh air unit housing 301 is circular. When the fresh air unit housing 301 is in the forward air outlet position, the protruding housing portion 303 is the part of the fresh air unit housing 301 that protrudes from the plane where the first front air outlet 1011 and the second front air outlet 1021 are located, such as... Figure 7 As shown. In this way, whether the fresh air outlet 31 is sending air forward or mixing with the first air outlet 101 or the second air outlet 102, it will not affect the air delivery effect of the heat exchange air of the first air outlet 101 and the second air outlet 102.

[0049] Optionally, the front shell portion 11 is horizontally disposed. The first side shell portion 12 is located on one side of the front shell portion 11, and the second side shell portion 13 is located on the other side of the front shell portion 11.

[0050] Optionally, the first front air outlet 1011 and the first side air outlet 1012 are connected through each other, and no partition or baffle is required between them to form a single first air outlet 101; similarly, the second front air outlet 1021 and the second side air outlet 1022 are connected through each other, and no partition or baffle is required between them to form a single second air outlet 102. Figure 8 As shown.

[0051] Optionally, the angle between the first front air outlet 1011 and the first side air outlet 1012 is a1, and the angle between the second front air outlet 1021 and the second side air outlet 1022 is a2, wherein 125°≤a1≤150°; and / or, 125°≤a2≤150°; and / or, a1>a2. Figure 9 As shown.

[0052] Optionally, the included angle α1 between the first front air outlet 1011 and the first side air outlet 1012 can be 125°, 128°, 130°, 132°, 135°, 137°, 140°, 142°, 145°, 147° or 150°; similarly, the included angle α2 between the second front air outlet 1021 and the second side air outlet 1022 can be 125°, 128°, 130°, 132°, 135°, 137°, 140°, 142°, 145°, 147° or 150°.

[0053] Optionally, a1 > a2. In this embodiment, the first air duct plate 32 of the fresh air unit housing 301 is close to the first air outlet 101, and the second air duct plate 33 is close to the second air outlet 102. When the fresh air outlet 31 faces the first air outlet 101, the second flat end 332 of the second air duct plate 33 forms the side that forms the main air supply direction, resulting in a weaker air gathering effect and a lower wind speed. Figure 11 As shown; when the fresh air outlet 31 faces the second air outlet 102, the first tip 321 of the first air duct plate 32 forms the side that forms the main air supply direction, resulting in a relatively strong air gathering effect and a higher wind speed, such as... Figure 12 As shown. At this time, the angle between the first side air outlet 1012 and the first front air outlet 101 of the first air outlet 101 should not be too small, which is beneficial to improving the mixing effect of the fresh air delivered by the fresh air outlet 31 and the heat exchange air delivered by the first side air outlet 1012. Optionally, a1 can be 130°, 132°, 135° or 137°, and a2 can be 125° or 128°.

[0054] Optionally, a fresh air damper is also provided at the fresh air outlet 31. When the first front air outlet 1011 is open and the first side air outlet 1012 is closed, the fresh air damper is fully open; when the first front air outlet 1011 is closed and the first side air outlet 1012 is open, the fresh air damper closes part of the fresh air outlet 31 from the second flat end 332.

[0055] A first air guide damper is provided at the first front air outlet 1011 to open or close the first front air outlet 1011, and a second air guide damper is provided at the first side air outlet 1012 to open or close the first side air outlet 1012.
