Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
The fan assembly 2 of the air conditioner outdoor unit 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1 to 3, a fan assembly 2 of an air conditioner outdoor unit 100 according to an embodiment of the present invention includes: a first wind wheel 21, a second wind wheel 22 and a drive assembly 3.
Wherein the first wind wheel 21 includes a plurality of first blades 211 spaced apart in a circumferential direction thereof, and the second wind wheel 22 includes a plurality of second blades 221 spaced apart in the circumferential direction thereof. The second wind wheel 22 may be located downstream of the first wind wheel 21 in the flow direction of the air flow and the second wind wheel 22 may be spaced apart from the first wind wheel 21. The drive assembly 3 may cooperate with the first wind wheel 21 and the second wind wheel 22, respectively, to drive the first wind wheel 21 and the second wind wheel 22 in rotation.
Specifically, since the first wind wheel 21 and the second wind wheel 22 may be disposed opposite to each other in the direction in which the airflow circulates, the first wind wheel 21 and the second wind wheel 22 may constitute a counter-rotating wind wheel, and both the first wind wheel 21 and the second wind wheel 22 may be axial flow wind wheels. When the fan assembly 2 works, the driving assembly 3 can respectively drive the first wind wheel 21 and the second wind wheel 22 to rotate, and the rotation directions of the first wind wheel 21 and the second wind wheel 22 can be opposite. Therefore, the tangential speeds of the air flow at the blade outlets of the first blades 211 are opposite to those of the air flow at the blade outlets of the second blades 221 and can be partially or completely offset, so that a nearly pure axial straight air flow can be obtained, that is, most or even all air flows can be blown out along the axial direction of the fan assembly 2, thereby increasing the air supply quantity and the air supply distance of the fan assembly 2 and further improving the air supply efficiency of the fan assembly 2.
It can be understood that, compared with a single cross flow wind wheel, an axial flow wind wheel or an oblique flow wind wheel, the first wind wheel 21 and the second wind wheel 22 in the counter wind wheel can rotate simultaneously, so that the air supply quantity and the air supply efficiency of the counter wind wheel are maximum on the premise that the driving assembly 3 consumes the same power. Therefore, the power consumption of the rotating wheel is also minimum on the premise of meeting the same air supply amount requirement. Therefore, the fan assembly 2 provided by the invention has the double functions of improving the air supply efficiency and reducing the energy consumption, and has extremely strong practical performance.
As shown in fig. 2, the extension length of the first wind wheel 21 along the axial direction (the front-rear direction as shown in fig. 2) may be L 1, the extension length of the second wind wheel 22 along the axial direction may be L 2, and the distance L 0 between the first wind wheel 21 and the second wind wheel 22 may satisfy the relationship: 0.2 (L 1+L2)≤L0≤1.5(L1+L2). Specifically, when the fan assembly 2 rotates, the tail portions of the first blade 211 and the second blade 221 may form tip leakage vortex due to the rotational wind, wherein the tail portion of the first blade 211 may be understood as a portion of the first blade 211 near the second blade 221, and the tail portion of the second blade 221 may be understood as a portion of the second blade 221 away from the first blade 211. The tip leakage vortex generated by the first blade 211 collides with the second blade 221 when passing through the second wind wheel 22, thereby generating relatively large noise.
It will be appreciated that when L 0＜0.2(L1+L2) is smaller the separation between the first rotor 21 and the second rotor 22, the tip leakage vortex can be circulated to the second rotor 22 in a short time after generation, whereby the impact force acting on the second blade 221 is larger, thereby generating a larger noise. When L 0＞1.5(L1+L2) is used, the distance between the first wind wheel 21 and the second wind wheel 22 is too large, so that the flow speed loss of the air flow generated by the first wind wheel 21 is large, and the air supply efficiency of the fan assembly 2 is reduced. When 0.2 (L 1+L2)≤L0≤1.5(L1+L2), the interval between the first wind wheel 21 and the second wind wheel 22 is set reasonably, the strength of the tip leakage vortex generated by the first blade 211 is reduced in the process of flowing from the first wind wheel 21 to the second wind wheel 22, so that the collision force acting on the second blade 221 can be reduced, and the noise generated by the fan assembly 2 can be reduced. Moreover, at this time, the space between the first wind wheel 21 and the second wind wheel 22 has less influence on the air supply speed of the fan assembly 2, so that the air supply efficiency of the fan assembly 2 can be ensured.
In the specific example shown in fig. 8, the extension length L 1 = 60mm of the first wind wheel 21 in the axial direction thereof, the extension length L 2 = 40mm of the second wind wheel 22 in the axial direction thereof, the size of the interval between the first wind wheel 21 and the second wind wheel 22 (L 0＝20mm、L0＝30mm、L0 =40 mm) is controlled respectively and the amount of noise generated by the fan assembly 2 at different intervals is detected. As can be seen from the graph shown in fig. 8, on the premise that the fan assembly 2 generates the same air volume, the noise generated by the fan assembly 2 is maximum when L 0 =20mm, i.e., L 0＝0.2(L1+L2), and the noise generated by the fan assembly 2 is greatly reduced compared with the noise generated when L 0＝0.2(L1+L2) when L 0 =30mm, i.e., L 0＝0.3(L1+L2), and the noise is reduced by about 2.0dB (a). L 0 = 40mm, i.e. L 0＝0.4(L1+L2) the noise generated by the fan assembly 2 is minimal, the magnitude of the noise reduction between L 0＝0.3(L1+L2) and L 0＝0.4(L1+L2) is much smaller than the magnitude of the noise reduction between L 0＝0.2(L1+L2) and L 0＝0.3(L1+L2).
According to the fan assembly 2 of the air-conditioning outdoor unit 100 of the embodiment of the invention, the first wind wheel 21 and the second wind wheel 22 which are arranged at intervals in the air-air flow direction can play a double role of improving the air supply efficiency and reducing the energy consumption, and the practicability of the fan assembly 2 can be improved. Through control 0.2 (L 1+L2)≤L0≤1.5(L1+L2), can reduce the noise that fan subassembly 2 produced under the prerequisite that satisfies the air supply demand to can promote user's use comfort.
According to some embodiments of the present invention, the distance L 0 between the first wind wheel 21 and the second wind wheel 22 may further satisfy the relation: 0.3 (L 1+L2)≤L0≤1.5(L1+L2). The inventor has verified through many tests that when 0.3 (L 1+L2)≤L0≤1.5(L1+L2), the fan assembly 2 can not only meet the air supply requirement, but also the noise generated by the fan assembly 2 is smaller. Alternatively, L 0 may be 0.5 (L 1+L2),L0 may be 0.8 (L 1+L2),L0 may be L 1+L2) As shown in FIG. 3, according to some embodiments of the present invention, the driving assembly 3 may include a first motor 31, a second motor 32, and a motor bracket 33, the first motor 31 and the second motor 32 may be respectively disposed on the motor bracket 33, the first motor 31 may be connected to the first wind wheel 21 to drive the first wind wheel 21 to rotate, and the second motor 32 may be connected to the second wind wheel 22 to drive the second wind wheel 22 to rotate.
Alternatively, the first motor 31 and the second motor 32 may be stepper motors, which have advantages of stable operation, and accurate control of the rotation direction and rotation number, so as to improve the air supply stability of the fan assembly 2.
Alternatively, the first motor 31 may be located downstream of the first wind wheel 21 and the second motor 32 may be located upstream of the second wind wheel 22 in the flow direction of the air flow, and the first motor 31 and the second motor 32 may be formed as a "back-to-back" type mating structure. Alternatively, the first motor 31 may be located upstream of the first wind wheel 21 and the second motor 32 may be located downstream of the second wind wheel 22 in the flow direction of the air flow, and the first motor 31 and the second motor 32 may be formed as a "face-to-face" mating structure. Alternatively, the first motor 31 may be located upstream of the first wind wheel 21 and the second motor 32 may be located upstream of the second wind wheel 22 in the flow direction of the air flow. Alternatively, the first motor 31 may be located downstream of the first wind wheel 21 and the second motor 32 may be located downstream of the second wind wheel 22 in the flow direction of the air flow.
In the specific example shown in fig. 3, the motor bracket 33 may include a vertically extending support plate 331, a first mounting groove 331a being provided on a rear sidewall of the support plate 331, a second mounting groove 331b being provided on a front sidewall of the support plate 331, the first and second mounting grooves 331a and 331b being disposed opposite to each other in a front-rear direction. Wherein the first motor 31 may be disposed in the first mounting groove 331a, and the second motor 32 may be disposed in the second mounting groove 331 b. Therefore, through the arrangement, the structural design form of the motor bracket 33 can be simpler, and the first motor 31 and the second motor 32 can be conveniently fixed.
According to some embodiments of the present invention, the driving assembly 3 may include a biaxial motor and a motor bracket 33, the biaxial motor may be provided on the motor bracket 33, the biaxial motor may have a first motor shaft and a second motor shaft, the first motor shaft may be connected to the first wind wheel 21, and the second motor shaft may be connected to the second wind wheel 22. When the driving assembly 3 works, the first motor shaft and the second motor shaft can rotate simultaneously, so that the double-shaft motor can drive the first wind wheel 21 and the second wind wheel 22 to rotate simultaneously. Through the arrangement, the whole structure of the driving assembly 3 is simpler and more compact, the assembly efficiency of the fan assembly 2 can be improved, and the assembly space occupied by the driving assembly 3 can be reduced.
As shown in fig. 4 and fig. 6-7, according to some embodiments of the present invention, the fan assembly 2 may further include two wind guide rings 4, each wind guide ring 4 may define a wind guiding space therein, and the first wind wheel 21 and the second wind wheel 22 may be disposed in the corresponding wind guiding spaces. When the fan assembly 2 works, the air guide ring 4 can play a role in guiding air, so that air flow can be prevented from being dispersed to the periphery, and can circulate along the air guide space, and the air supply efficiency of the fan assembly 2 can be improved. Moreover, as the wind guide ring 4 is sleeved on the corresponding first wind wheel 21 and second wind wheel 22, the tip leakage vortex generated by the first wind wheel 21 and the second wind wheel 22 during rotation can be reduced, and the working noise generated by the fan assembly 2 can be reduced.
In the specific embodiment shown in fig. 9, two fan assemblies 2 in the present invention are selected, wherein one fan assembly 2 is provided with a driving assembly 3, a first wind wheel 21 and a second wind wheel 22, the other fan assembly 2 comprises the driving assembly 3, the first wind wheel 21, the second wind wheel 22 and two wind guide rings 4, and the two wind guide rings 4 are sleeved on the first wind wheel 21 and the second wind wheel 22 in a one-to-one correspondence. The two fan assemblies 2 are controlled to generate the air quantity with the same size, and the power consumed by the two fan assemblies 2 is detected respectively. Wherein, the solid line in the graph shown in fig. 9 represents the power versus air volume curve of the fan assembly 2 without the air guide ring 4, and the broken line in the graph shown in fig. 9 represents the power versus air volume curve of the fan assembly 2 with the air guide ring 4. As is clear from fig. 9, when the two fan assemblies 2 generate the same air volume, the fan assembly 2 without the air guide ring 4 consumes more power than the fan assembly 2 with the air guide ring 4. Therefore, according to comparative analysis, the air guide ring 4 can play a role in improving the air supply efficiency of the fan assembly 2 and reducing the power consumption of the fan assembly 2.
In the specific embodiment shown in fig. 10, two fan assemblies 2 in the present invention are selected, wherein one fan assembly 2 is provided with a driving assembly 3, a first wind wheel 21 and a second wind wheel 22, the other fan assembly 2 comprises the driving assembly 3, the first wind wheel 21, the second wind wheel 22 and two wind guide rings 4, and the two wind guide rings 4 are respectively sleeved on the first wind wheel 21 and the second wind wheel 22 in a one-to-one correspondence. The two fan assemblies 2 are controlled to generate air quantity with the same size, and the noise generated by the two fan assemblies 2 is detected respectively. Wherein, the solid line in the graph shown in fig. 10 represents the variation curve of noise generated by the fan assembly 2 without the wind guide ring 4 with the air volume, and the broken line in the graph shown in fig. 10 represents the variation curve of noise generated by the fan assembly 2 with the wind guide ring 4 with the air volume. As is clear from fig. 10, when the two fan assemblies 2 generate the same air volume, the fan assembly 2 without the air guide ring 4 generates more noise than the fan assembly 2 with the air guide ring 4. From this, it is known through comparative analysis that the wind guide ring 4 can play a role in reducing noise of the fan assembly 2.
As shown in fig. 6, in some embodiments of the present invention, the wind guiding ring 4 may be sleeved on the first wind wheel 21 and spaced from the first wind wheel 21, the diameter of the first wind wheel 21 may be D 1, and the radial gap D 1 between the wind guiding ring 4 and the first wind wheel 21 may be 0.01D 1～0.03D1, that is, 0.01D 1≤d1≤0.03D1. It can be appreciated that when d 1＜0.01D1 is too small, the radial gap between the first wind wheel 21 and the wind guiding ring 4 is too small, the first wind wheel 21 can generate negative pressure when rotating, only a small part of air flow can enter the wind guiding ring 4 through the radial gap between the first wind wheel 21 and the wind guiding ring 4 under the action of the negative pressure, and most of air flow collides with the first wind wheel 21, so that the wind collecting effect of the wind guiding ring 4 is affected, and the air supply efficiency of the fan assembly 2 is reduced. When d 1＞0.03D1, the intensity of the tip leakage vortex generated by the first blade 211 increases, thereby increasing the collision force of the air flow on the second blade 221, and thus increasing the noise generated by the fan assembly 2. When 0.01D 1≤d1≤0.03D1, can reduce the noise that fan assembly 2 produced under the air supply efficiency prerequisite of fan assembly 2, can promote fan assembly 2's practicality greatly.

It will be appreciated that when d 2＜0.01D2 is too small, the radial gap between the second wind wheel 22 and the wind guiding ring 4 is too small, the second wind wheel 22 can generate negative pressure when rotating, under the action of the negative pressure, only a small part of air flow can enter the wind guiding ring 4 through the radial gap between the second wind wheel 22 and the wind guiding ring 4, and most of air flow collides with the second wind wheel 22, thereby affecting the wind collecting effect of the wind guiding ring 4 and reducing the air supply efficiency of the fan assembly 2. When d 2＞0.03D2, the intensity of the tip leakage vortex generated by the second vane 221 increases, thereby increasing the collision force of the air flow on the air outlet frame of the air conditioner outdoor unit 100, and further increasing the noise generated by the fan assembly 2. When 0.01D 2≤d2≤0.03D2, can reduce the noise that fan assembly 2 produced under the air supply efficiency prerequisite of fan assembly 2, can promote fan assembly 2's practicality greatly.

It can be appreciated that the first expansion part 41 can increase the air inlet area of the air inlet end of the air guide ring 4, and can reduce the circulation resistance of air flow, thereby reducing the power consumption of the driving assembly 3 and improving the air collecting effect of the air guide ring 4.
Alternatively, the first diffuser portion 41 may extend from the air inlet end of the air guide ring 4 to the air outlet end of the air guide ring 4. Therefore, in the flowing direction of the air flow, the ventilation area of the air guide ring 4 is gradually reduced, so that the flowing speed of the air flow in the air guide ring 4 can be increased, and the air supply efficiency of the fan assembly 2 can be improved.
As shown in fig. 4 and 6-7, in some embodiments of the present invention, the air outlet end of the air guiding ring 4 may be provided with a second diffuser portion 42, and the second diffuser portion 42 may extend in a direction away from the central axis of the air guiding ring 4 along the flowing direction of the air flow. It will be appreciated that the second diffuser portion 42 may increase the air outlet area of the air outlet end of the air guide ring 4, thereby reducing the flow resistance of the air flow, and thus reducing the power consumption of the driving assembly 3.
Alternatively, the second diffuser portion 42 may extend from the air outlet end of the air guide ring 4 to the air inlet end of the air guide ring 4. In this way, the ventilation area of the air guide ring 4 is gradually increased in the ventilation direction of the air flow, so that the ventilation resistance of the air flow in the air guide ring 4 can be reduced, and the power consumption of the driving assembly 3 can be reduced.

In the flow direction of the air flow, the first diffuser portion 41 extends in a direction toward the central axis of the air guide ring 4, and the second diffuser portion 42 extends in a direction away from the central axis of the air guide ring 4. The diameter of the straight section 43 is the same as the smallest diameter of the first flared section 41 and remains unchanged in the flow direction of the air stream. Therefore, through the arrangement, the structural design of the wind guide ring 4 can be more reasonable, and the wind collecting effect and the wind guiding effect of the wind guide ring 4 can be improved.

Alternatively, at least one wind guiding ring 4 and the wind channel mounting plate 5 may be formed as an integral part, that is, the wind guiding ring 4 sleeved on the first wind wheel 21 and the wind channel mounting plate 5 may be provided as an integral part, the wind guiding ring 4 sleeved on the second wind wheel 22 and the wind channel mounting plate 5 may be provided as an integral part, and two wind guiding rings 4 and the wind channel mounting plate 5 may be provided as an integral part at the same time. Therefore, through the arrangement, the structure of the fan assembly 2 can be simplified, and accordingly the assembly efficiency of the fan assembly 2 can be improved. Moreover, the air guide ring 4 and the air duct mounting plate 5 are arranged into an integrated part, so that the sealing performance of the matching structure between the air guide ring 4 and the air duct mounting plate 5 is better, and the working noise of the fan assembly 2 can be reduced.
As shown in fig. 5 to 7, an air conditioner outdoor unit 100 according to an embodiment of the present invention includes: the casing 1, the outdoor heat exchanger 6 and the fan assembly 2 according to the above embodiment of the present invention, wherein the casing 1 may be provided with an air inlet 1a and an air outlet 1b, and the outdoor heat exchanger 6 and the fan assembly 2 are respectively provided in the casing 1.

For example, the first wind wheel 21 and the second wind wheel 22 may be axial flow wind wheels, and the outdoor heat exchanger 6, the first wind wheel 21 and the second wind wheel 22 are sequentially distributed in the flowing direction of the air flow, wherein the front side and the rear side of the outdoor heat exchanger 6 are respectively opposite to the first wind wheel 21 and the air inlet 1a, and the front side of the second wind wheel 22 is opposite to the air outlet 1 b. Thus, when the air conditioner outdoor unit 100 is in operation, the fan assembly 2 rotates to form a negative pressure, and the air flow circulates from back to front under the action of the negative pressure, and the air flow entering the casing 1 from the air inlet 1a directly flows to the outdoor heat exchanger 6 and exchanges heat with the outdoor heat exchanger 6. Thus, by the above arrangement, the heat exchange efficiency of the outdoor heat exchanger 6 is greatly improved.

As shown in fig. 2, the extension length of the first wind wheel 21 along the axial direction thereof may be L 1, the extension length of the second wind wheel 22 along the axial direction thereof may be L 2, and the distance L 0 between the first wind wheel 21 and the second wind wheel 22 satisfies the relationship: l 0＝0.5(L1+L2).

The wind guide rings 4 sleeved on the first wind wheel 21 and the second wind wheel 22 comprise a first expansion part 41, a second expansion part 42 and a straight cylinder section 43, and the first expansion part 41 and the second expansion part 42 are arranged in the axial direction of the straight cylinder section 43 and are respectively connected with the straight cylinder section 43. In the flow direction of the air flow, the first diffuser portion 41 extends in a direction toward the central axis of the air guide ring 4, and the second diffuser portion 42 extends in a direction away from the central axis of the air guide ring 4. The diameter of the straight section 43 is the same as the smallest diameter of the first flared section 41 and remains unchanged in the flow direction of the air stream. One of the two air guide rings 4 and the air duct mounting plate 5 form an integrated part, and the other air guide ring 4 is connected with the air duct mounting plate 5 through screws.
