It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0030] Please refer to Figures 1 to 9The utility model provides an air duct assembly, which is suitable for an air conditioner outdoor unit. The air conditioner outdoor unit has a cavity 1, and the air duct assembly includes: an air duct component 10, which is arranged in the cavity 1, and the air duct component 10 has an air duct inlet 11 and an air duct outlet 12 which are relatively arranged. The air duct inlet 11 is connected to the cavity 1, and the air duct outlet 12 is connected to the external environment, so that the gas in the cavity 1 flows through the air duct inlet 11 and the air duct outlet 12 in sequence and is discharged to the external environment; the air duct component 10 can rotate around a preset rotating shaft so that the air duct inlet 11 is arranged toward the top space of the cavity 1, the bottom space of the cavity 1, or the middle space of the cavity 1.

[0031] The air duct assembly of the present invention includes an air duct component 10, and the air duct component 10 includes an air duct inlet 11 and an air duct outlet 12. The air duct component 10 can rotate around a preset rotation axis, thereby changing the direction of the air duct inlet 11, so that when the gas in the cavity 1 is deposited at the top, bottom or middle space of the cavity 1, the air duct inlet 11 can correspond to the position where the gas is accumulated, thereby ensuring that when the gas properties in the cavity 1 are different, the gas in the cavity 1 can fully flow into the air duct inlet 11 and then be discharged to the external environment through the air duct outlet 12, thereby ensuring that the exhaust direction of the air conditioner outdoor unit is flexible and adjustable, thereby solving the problem of the single exhaust direction of the air conditioner outdoor unit in the prior art and improving the exhaust efficiency of the air duct assembly.

[0032] Specifically, the middle space of the cavity 1 corresponds to the space corresponding to the air duct component 10 when the air duct component 10 is just fitted with the connecting port 7 on the outdoor unit housing 5; the top space of the cavity 1 corresponds to the space inside the cavity 1 close to the top shell of the air-conditioning outdoor unit; the bottom space of the cavity 1 corresponds to the space inside the cavity 1 close to the bottom shell of the air-conditioning outdoor unit.

[0033] During specific implementation, the user can flexibly adjust the direction of the air duct inlet 11 according to the actual working temperature of the condenser, thereby adjusting the exhaust efficiency of the air conditioner outdoor unit.

[0034] When implementing it, Figure 8 and Fig. 9 As shown, the air duct component 10 can be manually adjusted according to user needs. For example, some air-conditioning outdoor units will use shutters 8 for protection during installation. However, the shutters 8 are not conducive to the discharge of heat dissipation gas from the air-conditioning outdoor unit. Under the traditional horizontal air supply state, the air duct outlet 12 forms an angle with the shutters 8, which will form a vortex in the window and the gas cannot be discharged smoothly. At this time, the direction of the air duct outlet 12 can be manually adjusted according to the direction and angle of the blades of the shutters to make it compatible with the shutters, which can greatly improve the smoothness of the exhaust and improve the heat dissipation performance of the outdoor unit.

[0035] In the prior art, when the air conditioner indoor unit is in the heating mode, the refrigerant in the pipeline releases heat on the air conditioner indoor unit side to produce warm air, and absorbs heat on the air conditioner outdoor unit side to form cold air. The condenser of the air conditioner outdoor unit is in a low-temperature state, and the cold air gas emitted from the condenser pipeline has a large gas density, sinks and gathers at the bottom of the air conditioner outdoor unit; when the air conditioner indoor unit is in the cooling mode, the refrigerant in the pipeline absorbs heat on the air conditioner indoor unit side to produce cold air, and releases heat on the air conditioner outdoor unit side to form warm air. The condenser of the air conditioner outdoor unit is in a high-temperature state, and the warm air gas emitted from the condenser pipeline has a large gas density, rises and gathers at the top of the air conditioner outdoor unit.

[0036] In this embodiment, if Figures 5 to 7 As shown, when the air duct inlet 11 is set toward the top space of the cavity 1, the air duct component 10 is in the first rotation position; when the air duct inlet 11 is set toward the bottom space of the cavity 1, the air duct component 10 is in the second rotation position; wherein the air-conditioning outdoor unit is connected to the air-conditioning indoor unit; when the air-conditioning indoor unit is in cooling mode, the air duct component 10 is in the first rotation position; when the air-conditioning indoor unit is in heating mode, the air duct component 10 is in the second rotation position.

[0037] Specifically, when the air-conditioning indoor unit is in cooling mode, the air duct component 10 is in a first rotation position, and the air duct inlet 11 is arranged toward the top space of the cavity 1, so as to discharge the gas accumulated on the top of the cavity 1, accelerate the gas circulation at the top of the cavity 1, and prevent the temperature of the cavity 1 from continuously increasing, causing the condenser to shut down, thereby affecting the cooling capacity; when the air-conditioning indoor unit is in heating mode, the air duct component 10 is in a second rotation position, and the air duct inlet 11 is arranged toward the bottom space of the cavity 1, so as to discharge the gas accumulated on the bottom of the cavity 1, accelerate the gas circulation at the bottom of the cavity 1, and prevent the temperature of the cavity 1 from continuously decreasing, causing the condenser to shut down, thereby affecting the heating capacity; therefore, when the air-conditioning indoor unit is in different working modes, the air duct component 10 is in different rotation positions, so as to fully discharge the gas in the cavity 1, thereby further improving the exhaust efficiency of the air duct assembly.

[0038] In this embodiment, if Figures 5 to 7 As shown, when the duct inlet 11 is arranged toward the middle space of the cavity 1, the duct component 10 is in the third rotation position; the angle between the direction of the duct inlet 11 and the first preset direction is θ, when the duct component is in the third rotation position, θ is equal to 0°, and the duct component 10 is in the initial position; when the duct component 10 is in the first rotation position, θ is equal to -30°; when the duct component 10 is in the second rotation position, θ is equal to 30°; and / or, the duct component 10 includes a fan blade 199, and the rotation axis direction of the fan blade 199 is set at a preset angle to the preset rotation axis.

[0039] Specifically, such a configuration ensures that when the air duct component 10 is in the first rotation position, the air duct inlet 11 is arranged exactly toward the top space of the cavity 1; when the air duct component 10 is in the second rotation position, the air duct inlet 11 is arranged exactly toward the bottom space of the cavity 1, thereby ensuring that the air duct inlet 11 can be fully oriented toward the position where gas accumulates.

[0040] Specifically, when the indoor unit of the air conditioner is just started, the air duct component is in the third rotation position, at which time the fan blades 199 are in a horizontal position, and at this time the temperature in the cavity 1 is close to the temperature of the external environment.

[0041] Specifically, the first preset direction is as follows: Figure 5 In the horizontal direction shown, the rotation axis direction of the fan blade 199 is set at an angle of 90° with the preset rotation axis.

[0042] In this embodiment, if Figure 3 and Figure 4 As shown, the air duct assembly further includes: a support structure 20 disposed in the cavity 1, and the air duct component 10 is rotatably disposed on the support structure 20 around a preset rotation axis.

[0043] Specifically, the support structure 20 is used to support the air duct component 10 to ensure that the air duct component 10 can rotate around a preset rotation axis.

[0044] In this embodiment, if Figure 3 and Figure 4 As shown, the support structure 20 includes a first support member 21 and a second support member 22 that are spaced apart. One side of the duct component 10 is rotatably connected to the first support member 21 , and the other side of the duct component 10 is rotatably connected to the second support member 22 .

[0045] Specifically, the air duct component 10 is supported from both sides by the first support member 21 and the second support member 22 respectively, thereby ensuring the reliability of the support structure 20 for the air duct component 10 and further ensuring that the air duct component 10 can rotate around a preset rotation axis.

[0046] In this embodiment, if Figure 4As shown, the air duct assembly also includes an air duct 18 and a mounting frame 19, the opposite ends of the air duct 18 are respectively an air duct inlet 11 and an air duct outlet 12, two connecting shafts 13 are arranged on the side wall of the air duct 18, and the two connecting shafts 13 are arranged at intervals on both sides of the air duct 18 along the extension direction of the preset rotating shaft; the mounting frame 19 is sleeved on the air duct 18, and two shaft sleeves 191 are arranged on the mounting frame 19, and the two connecting shafts 13 are arranged one-to-one with the two shaft sleeves 191; a first penetration hole 211 is arranged on the first support member 21, and a second penetration hole 212 is arranged on the second support member 22, and the two connecting shafts 13 are respectively penetrated into the corresponding shaft sleeves 191 and then penetrated into the first penetration hole 211 and the second penetration hole 212, so that the two sides of the air duct component 10 are respectively connected to the first support member 21 and the second support member 22.

[0047] Specifically, by passing the connecting shaft 13 into the corresponding sleeve 191, the air duct 18 is fixedly connected to the mounting frame 19; by passing the two connecting shafts 13 into the first penetration hole 211 and the second penetration hole 212 respectively, the two sides of the air duct component 10 are respectively connected to the first support member 21 and the second support member 22. Such an arrangement ensures the reliability of the connection between the air duct component 10 and the first support member 21 and the second support member 22, thereby ensuring the reliability of the support structure 20 for the air duct component 10.

[0048] In this embodiment, if Figure 1 As shown, the air duct assembly further includes: a driving structure, which is drivingly connected to the air duct component 10 so that the air duct component 10 can rotate around a preset rotation axis. Such a setting enables the driving structure to provide rotational power to the air duct component 10, thereby ensuring that the air duct component 10 can rotate smoothly around the preset rotation axis.

[0049] In this embodiment, if Figure 1 As shown, the driving structure includes: a driving gear 30, which is rotatably arranged on the first support member 21 and / or the second support member 22; a driven gear 40, which is connected to the air duct component 10; and a driving member 50, which is drivingly connected to the driving gear 30; wherein the driving gear 30 and the driven gear 40 are meshed with each other, so that the driving member 50 drives the driven gear 40 to rotate through the driving gear 30, so as to drive the air duct component 10 to rotate around a preset rotation axis.

[0050] Specifically, the driving member 50 drives the driving gear 30 to rotate, the driving gear 30 drives the driven gear 40 to rotate, and the driven gear 40 drives the air duct component 10 to rotate, further ensuring the driving reliability of the driving structure for the air duct component 10, thereby ensuring that the air duct component 10 can rotate smoothly around the preset rotation axis. Among them, the driving member 50 is a motor.

[0052] Specifically, the driven gear 40 drives the air duct component 10 to rotate through the connecting shaft 13 , and at the same time, the driven gear 40 serves to axially limit the connecting shaft 13 to prevent the connecting shaft 13 from being disconnected from the supporting structure 20 .

Thus, the exhaust direction of the air conditioner outdoor unit is ensured to be flexible and adjustable, thereby solving the problem of the single exhaust direction of the air conditioner outdoor unit in the prior art, and improving the exhaust efficiency of the air duct assembly.
