Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, specifically to an air supply component, an air conditioner, and an air handling equipment. Background Technology

[0002] In related technologies, the air supply components have fixed air inlet and outlet directions, such as only being able to supply air in a specific direction, which restricts the airflow direction. This not only affects the applicability of the air supply components in different scenarios, but also makes it difficult to meet diverse air conditioning needs. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides an air supply component, an air conditioner, and an air handling equipment.

[0004] According to a first aspect of the present disclosure, an air supply assembly is provided, including a first air duct, a second air duct, a first cross-flow impeller, a second cross-flow impeller, and a motor. A first air outlet and a second air outlet are respectively formed at both ends of the first air duct, and a third air outlet and a fourth air outlet are respectively formed at both ends of the second air duct. The first cross-flow impeller is disposed in the first air duct, and the second cross-flow impeller is disposed in the second air duct. The rotating shaft of the motor passes through and is connected to the first cross-flow impeller and the second cross-flow impeller in sequence, and is capable of driving the first cross-flow impeller and the second cross-flow impeller to rotate forward, or driving the first cross-flow impeller and the second cross-flow impeller to rotate in reverse. The air outlet direction of at least one of the third and fourth air outlets is different from the air outlet direction of the first and second air outlets.

[0005] In some possible implementations, the bending direction of the blades of the first cross-flow impeller is different from that of the blades of the second cross-flow impeller. Because the bending direction of the blades of the first cross-flow impeller is different from that of the blades of the second cross-flow impeller, regardless of the direction in which the motor's rotating shaft rotates (e.g., clockwise or counterclockwise), at least one of the first and second cross-flow impellers can be driven to achieve efficient air delivery in a specific direction.

[0006] In some possible implementations, one of the blades of the first cross-flow impeller and the second cross-flow impeller is bent clockwise, and the other is bent counterclockwise. In the implementation where the blades of the first cross-flow impeller are bent clockwise and the blades of the second cross-flow impeller are bent counterclockwise, when the motor's rotating shaft rotates clockwise, it drives the first cross-flow impeller to rotate. The clockwise-bent first cross-flow impeller efficiently pushes air forward (or in a specific direction), and the airflow exits from one of the first and second air inlets, achieving efficient air delivery. Similarly, when the motor's rotating shaft rotates counterclockwise, it drives the second cross-flow impeller to rotate. The counterclockwise-bent second cross-flow impeller efficiently pushes air downward (or in a specific direction), and the airflow exits from one of the third and fourth air inlets, achieving efficient air delivery.

[0007] In some possible implementations, at least one of the first and second air ducts includes a first guide section, a second guide section, and an intermediate section, wherein the intermediate section connects the first and second guide sections, and at least one of the first and second cross-flow impellers is disposed within the corresponding intermediate section. When the motor's rotating shaft rotates forward, under the action of the first cross-flow impeller, air can be drawn in from the first air inlet, enter the intermediate section through the first guide section, and then be discharged from the second air inlet after being guided by the second guide section. Similarly, when the motor's rotating shaft rotates in reverse, under the action of the second cross-flow impeller, air can be drawn in from the third air inlet, enter the intermediate section through the second guide section, and then be discharged from the fourth air inlet under the guidance of the first guide section after being guided by the second cross-flow impeller. In the above process, by rotating the motor forward and reverse, airflow is achieved in different ducts and different air inlets, thereby increasing the direction and range of air delivery.

[0008] In some possible implementations, along the direction from the first guide section to the second guide section, the flow area of ​​the first air duct first increases and then decreases; and / or, Along the direction from the first guide section to the second guide section, the flow area of ​​the second air duct first increases and then decreases. That is, the flow areas of both the first and second guide sections are smaller than the flow area of ​​the middle section. Thus, as the airflow flows from the middle section to the first guide section or from the middle section to the second guide section, the inner diameter of the first and / or second air ducts contracts. This helps to achieve a more optimized airflow distribution within the entire first and / or second air ducts, reducing airflow separation and the generation of eddies. This further prevents the airflow from flowing back after exiting the impeller located in the middle section, thus affecting the air delivery efficiency.

[0009] In some possible implementations, the air supply assembly includes a first backflow suppression device and a second backflow suppression device. The first backflow suppression device is disposed within the first guide section, and the second backflow suppression device is disposed within the second guide section. By providing the first backflow suppression device within the first guide section and the second backflow suppression device within the second guide section, the problem of airflow backflowing towards the middle section when the first or second cross-flow impeller discharges airflow from the first or second guide section, thus affecting the air supply efficiency, can be avoided or reduced.

[0010] In some possible implementations, both the first backflow suppression device and the second backflow suppression device include a first protrusion, which is formed on the inner wall of the air duct and protrudes towards the interior of the airflow channel. That is, the aforementioned first protrusion is formed on the inner walls of the first and second guide sections, respectively. The arrangement of the first protrusion reduces the flow area of ​​the first and second guide sections, creating an obstacle within the air duct. This effectively suppresses backflow in the airflow, stabilizes the airflow direction, reduces reverse flow, and improves system stability. Furthermore, the first protrusion can guide the airflow along a specific path, reducing eddies and airflow turbulence, thereby improving overall flow efficiency.

[0011] In some possible implementations, the air supply assembly includes a third backflow suppression device disposed within the intermediate section. Both the first and second cross-flow impellers are located within the intermediate section. By providing the third backflow suppression device within the intermediate section, backflow can be prevented from forming after the airflow enters the impeller, thus avoiding any impact on air supply efficiency due to backflow.

[0012] In some possible implementations, the third backflow suppression device includes a second protrusion that protrudes toward the first and second cross-flow impellers. The second protrusion, protruding toward the first and second cross-flow impellers, reduces the distance between the first and second cross-flow impellers and the inner wall of the duct, thereby preventing or limiting airflow leakage and backflow after entering the impellers, thus avoiding impact on air delivery efficiency.

[0013] In some possible implementations, a first guide section of the first air duct extends upward, and a first air outlet is formed at the end of the first guide section; a second guide section of the first air duct extends downward at an angle, and a second air outlet is formed at the end of the second guide section; and / or, The first guide section of the second air duct extends forward, and the third air outlet is formed at the end of the first guide section. The second guide section of the second air duct extends downward, and the fourth air outlet is formed at the end of the second guide section. In the first air duct, the first guide section extends upward, and the first air outlet is located at its end, which can send the air upward. The second guide section extends downward at an angle, and the second air outlet is at its end, which can send the air downward at an angle. In this way, in the vertical direction, airflow can cover a certain range from top to bottom, which greatly increases the air supply range in the vertical space compared to traditional single-direction air supply.

[0014] In some possible implementations, the air duct further includes a third air duct, with a fifth air outlet and a sixth air outlet formed at each end of the third air duct. The air supply assembly also includes a third cross-flow impeller, which is disposed within the third air duct and coaxially arranged with the first and second cross-flow impellers. The rotating shaft of the motor passes through and is connected to the first, second, and third cross-flow impellers in sequence, and is capable of driving the third cross-flow impeller to rotate synchronously forward or in reverse with the first and second cross-flow impellers. By providing a third air duct, a third cross-flow impeller disposed within the third air duct, and fifth and sixth air outlets formed at both ends of the third air duct, the air supply volume and air supply range of the air supply assembly can be further increased, thereby achieving a better air supply effect.

[0015] In some possible implementations, the bending direction of the blades of the third cross-flow impeller is the same as that of the blades of the first cross-flow impeller. Since the motor drives the first and third cross-flow impellers to rotate synchronously forward or backward, the consistent blade bending direction allows the first and third cross-flow impellers to work together better, enabling the airflow to propel the air through their respective ducts with the same efficiency and manner. This improves the overall efficiency of the entire air supply assembly, making the air supply more stable and efficient.

[0016] In some possible implementations, the third cross-flow impeller is disposed on the side of the second cross-flow impeller away from the first cross-flow impeller. Since the first and third cross-flow impellers are respectively disposed on opposite sides of the second cross-flow impeller, and the bending direction of the blades of the third cross-flow impeller is consistent with the bending direction of the blades of the first cross-flow impeller, synchronous air delivery can be achieved when the motor drives the first, second, and third cross-flow impellers to rotate synchronously, thereby increasing the air delivery efficiency and range of the air delivery assembly.

[0017] In some possible implementations, the flow area of ​​the third air duct is equal to that of the first air duct. Since the flow area of ​​the third air duct is equal to that of the first air duct, when the motor is running, the airflow from both sides of the second air duct can affect the surrounding environment in a similar manner and intensity, making the airflow distribution in the room more uniform and avoiding localized overheating or overcooling.

[0018] In some possible implementations, the third air duct and the first air duct are symmetrically arranged on both sides of the second air duct, and / or, the third cross-flow impeller and the first cross-flow impeller are symmetrically arranged on both sides of the second cross-flow impeller. On the one hand, when the motor drives the three cross-flow impellers to rotate synchronously in both directions, the symmetrical air duct structure makes the force on the entire air supply assembly more balanced, reducing vibration and noise caused by unreasonable air duct layout; on the other hand, the symmetrical air outlet method can make the airflow distribution in the room more uniform, avoiding the phenomenon of excessive or insufficient local airflow, or excessively hot or cold temperatures.

[0019] In some possible implementations, the air supply assembly further includes a housing, which includes a top wall, a bottom wall, a side wall, and an inclined wall. The top wall is connected to the side wall, and the lower end of the side wall is connected to the bottom wall through the inclined wall. Both the first air duct and the second air duct are disposed within the housing. An upwind opening is formed on the top wall, and the upwind opening is connected to the first air vent. An inclined air vent is formed on the inclined wall and is arranged inclined downwards, and the inclined air vent is connected to the second air vent. A front air vent is formed on the side wall, and the front air vent communicates with the third air vent. A lower air vent is formed on the bottom wall, and the lower air vent communicates with the fourth air vent. In other words, air vents with different orientations are formed on different walls of the housing. This allows the air supply assembly to cover a larger space. Users can select different air vents for air supply according to actual needs, or open multiple air vents simultaneously to achieve diversified air supply modes, enhancing the applicability and flexibility of the product.

[0020] In some possible implementations, both the first and second cross-flow impellers include multiple sets of blades arranged circumferentially, with adjacent sets of blades spaced apart axially. The circumferentially arranged sets of blades allow the impeller to continuously interact with the air at different circumferential positions during rotation. As the impeller rotates, the blades continuously cut through the air, creating multiple airflow intake and exhaust zones, resulting in a more uniform airflow distribution within the duct. This prevents localized areas of excessively strong or weak airflow within the duct. Furthermore, the axially spaced blade sets further increase the airflow area, allowing more air to be drawn in and exhausted from the duct per unit time, thereby effectively improving the ventilation volume and air exchange efficiency of the duct.

[0021] According to a second aspect of the present disclosure, an air conditioner is provided, including the air supply assembly as described above.

[0022] In some possible implementations, the air conditioner includes a ducted unit.

[0023] According to a third aspect of the present disclosure, an air handling apparatus is provided, including the air supply assembly as described above or the air conditioner as described above.

[0024] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: When the motor drives the impeller to rotate forward, one of the first and second cross-flow impellers can drive the airflow to flow in one of the first and second flow channels. When the motor drives the impeller to rotate in reverse, the other of the first and second cross-flow impellers can drive the airflow to flow in the other of the first and second flow channels. This allows the airflow to flow out from different flow channels and different air outlets when the motor rotates forward and in reverse, thereby increasing the air delivery direction and air delivery range of the air delivery assembly.

[0025] Furthermore, in the above scheme, the air outlet direction of at least one of the third and fourth air outlets is different from that of the first and second air outlets. Through the directional difference between the third and fourth air outlets and the first and second air outlets, air can be delivered in more directions. The direct effect of more air outlet directions is to expand the air coverage of the air supply component in the space, thereby delivering air to a wider area, reducing dead air zones in the space, avoiding airflow concentration in one direction, reducing the unevenness of local air flow, and improving indoor air circulation and comfort.

Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, unless otherwise stated, directional terms are used only for the convenience of describing the disclosure and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation, and therefore should not be construed as a limitation of the disclosure. For example, directional terms in this scheme are defined based on the actual use of the vehicle. "Inner" and "outer" refer to the inner and outer contours of the corresponding components. Furthermore, the terms "first," "second," etc., are used to distinguish one element from another and do not have sequential or importance implications.

[0031] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0032] refer to Figures 1 to 6As shown, according to a first aspect of the present disclosure, an air supply assembly 1 is provided, including a first air duct 10, a second air duct 20, a first cross-flow impeller 30, a second cross-flow impeller 40, and a motor. A first air outlet 11 and a second air outlet 12 are formed at both ends of the first air duct 10, and a third air outlet 21 and a fourth air outlet 22 are formed at both ends of the second air duct 20. The first cross-flow impeller 30 is disposed within the first air duct 10, and the second cross-flow impeller 40 is disposed within the second air duct 20. The rotating shaft of the motor passes through and is connected to the first cross-flow impeller 30 and the second cross-flow impeller 40 in sequence, and is capable of driving the first cross-flow impeller 30 and the second cross-flow impeller 40 to rotate forward or in reverse. The air outlet direction of at least one of the third air outlet 21 and the fourth air outlet 22 is different from the air outlet direction of the first air outlet 11 and the second air outlet 12.

[0033] When the motor drives the impeller to rotate forward, one of the first cross-flow impeller 30 and the second cross-flow impeller 40 can drive the airflow to flow in one of the first flow channel and the second flow channel. When the motor drives the impeller to rotate in reverse, the other of the first cross-flow impeller 30 and the second cross-flow impeller 40 can drive the airflow to flow in the other of the first flow channel and the second flow channel. This allows the airflow to flow out from different flow channels and different air outlets when the motor rotates forward and in reverse, thereby increasing the air delivery direction and air delivery range of the air delivery assembly 1.

[0034] Furthermore, in the above scheme, the air outlet direction of at least one of the third air outlet 21 and the fourth air outlet 22 is different from that of the first air outlet 11 and the second air outlet 12. Through the directional difference between the third air outlet 21 and the fourth air outlet 22 and the first air outlet 11 and the second air outlet 12, air can be delivered in more directions. The direct effect of more air outlet directions is to expand the air coverage range of the air supply component 1 in the space, thereby delivering air to a wider area, reducing dead air in the space, avoiding airflow concentration in one direction, reducing the unevenness of local air flow, and improving indoor air circulation and comfort.

[0035] It should be noted that the fact that the air outlet direction of at least one of the aforementioned third air outlet 21 and fourth air outlet 22 is different from the air outlet direction of the first air outlet 11 and the second air outlet 12 can be understood as the air outlet direction of the third air outlet 21 being different from the air outlet direction of the first air outlet 11 and the second air outlet 12. Alternatively, it can be understood as the air outlet direction of the fourth air outlet 22 being different from the air outlet direction of the third air outlet 21 being different from the air outlet direction of the first air outlet 11 and the second air outlet 12. Or, it can be understood as the air outlet direction of the third air outlet 21 being different from the air outlet direction of the first air outlet 11 and the second air outlet 12, and the air outlet direction of the fourth air outlet 22 being different from the air outlet direction of the first air outlet 11 and the second air outlet 12.

[0036] Here, this disclosure does not restrict whether the air outlet directions of the third air outlet 21 and the fourth air outlet 22 are different, that is, the air outlet directions of the third air outlet 21 and the fourth air outlet 22 can be the same or different.

[0037] In some possible implementations, such as Figure 2 As shown, the bending direction of the blades 100 of the first cross-flow impeller 30 is different from that of the blades 100 of the second cross-flow impeller 40. Thus, because the bending directions of the blades 100 of the first cross-flow impeller 30 and the second cross-flow impeller 40 are different, regardless of the direction of rotation of the motor shaft (e.g., clockwise or counterclockwise), at least one of the first cross-flow impeller 30 and the second cross-flow impeller 40 can be driven to achieve efficient airflow in a specific direction.

[0038] In one embodiment provided in this disclosure, one of the blades 100 of the first cross-flow impeller 30 and the blades 100 of the second cross-flow impeller 40 is bent in a clockwise direction, and the other of the blades 100 of the first cross-flow impeller 30 and the blades 100 of the second cross-flow impeller 40 is bent in a counterclockwise direction. For example, in an embodiment where the blades 100 of the first cross-flow impeller 30 are bent clockwise and the blades 100 of the second cross-flow impeller 40 are bent counterclockwise, when the motor's rotating shaft rotates clockwise, it can drive the first cross-flow impeller 30 to rotate. The first cross-flow impeller 30, bent clockwise, can efficiently push air forward (or in a specific direction), and the airflow flows out from one of the first air outlet 11 and the second air outlet 12, achieving efficient air delivery. Similarly, when the motor's rotating shaft rotates counterclockwise, it can drive the second cross-flow impeller 40 to rotate. The second cross-flow impeller 40, bent counterclockwise, can efficiently push air downward (or in a specific direction), and the airflow flows out from one of the third air outlet 21 and the fourth air outlet 22, achieving efficient air delivery.

[0039] In some possible implementations, such as Figure 5 , Figure 6As shown, at least one of the first air duct 10 and the second air duct 20 includes a first guide section 14, a second guide section 15 and an intermediate section 16. The intermediate section 16 is connected between the first guide section 14 and the second guide section 15. At least one of the first cross-flow impeller 30 and the second cross-flow impeller 40 is disposed in the corresponding intermediate section 16. In this way, when the motor's rotating shaft rotates forward, under the action of the first cross-flow impeller 30, air can be drawn in from the first air inlet 11, enter the middle section 16 through the first guide section 14, and then be discharged from the second air inlet 12 after being guided by the second guide section 15. Similarly, when the motor's rotating shaft rotates in reverse, under the action of the second cross-flow impeller 40, air can be drawn in from the third air inlet 21, enter the middle section 16 through the second guide section 15, and then be discharged from the fourth air inlet 22 under the guidance of the first guide section 14 after being guided by the second cross-flow impeller 40. In the above process, by rotating the motor forward and reverse, the airflow can be made to flow in different channels and different air inlets, thereby increasing the direction and range of air supply.

[0040] In some possible implementations, such as Figure 5 , Figure 6 As shown, along the direction from the first guide section 14 to the second guide section 15, the flow area of ​​the first air duct 10 first increases and then decreases; and / or, along the direction from the first guide section 14 to the second guide section 15, the flow area of ​​the second air duct 20 first increases and then decreases. That is to say, the flow areas of both the first guide section 14 and the second guide section 15 are smaller than the flow area of ​​the intermediate section 16. Thus, as the airflow flows from the intermediate section 16 to the first guide section 14 or from the intermediate section 16 to the second guide section 15, the inner diameter of the first air duct 10 and / or the second air duct 20 contracts. This helps to achieve a more optimized airflow distribution within the entire first air duct 10 and / or the second air duct 20, reducing airflow separation and the generation of eddies. This further prevents the airflow from flowing back after exiting the impeller located in the intermediate section 16, thus affecting the air supply efficiency.

[0041] In some possible implementations, such as Figure 5 , Figure 6 As shown, the air supply assembly 1 may include a first backflow suppression device and a second backflow suppression device. The first backflow suppression device is disposed within the first guide section 14, and the second backflow suppression device is disposed within the second guide section 15. By distributing the first backflow suppression device within the first guide section 14 and the second backflow suppression device within the second guide section 15, the problem of airflow backflow towards the middle section 16 when the first cross-flow impeller 30 and the second cross-flow impeller 40 discharge airflow from the first guide section 14 or the second guide section 15, thus affecting the air supply efficiency, can be avoided or reduced.

[0042] This disclosure does not limit the specific structure of the first and second backflow suppression devices or the method of suppressing backflow. For example, Figure 5 , Figure 6 As shown, in one embodiment provided in this disclosure, both the first backflow suppression device and the second backflow suppression device include a first protrusion 17. The first protrusion 17 is formed on the inner wall of the air duct and protrudes towards the interior of the airflow channel. That is, the aforementioned first protrusion 17 is formed on the inner wall of the first guide section 14 and the second guide section 15, respectively. The arrangement of the first protrusion 17 reduces the flow area of ​​the first guide section 14 and the second guide section 15, and can form an obstacle in the air duct, effectively suppressing backflow in the airflow, stabilizing the airflow direction, reducing reverse flow, and improving the stability of the system. On the other hand, the arrangement of the first protrusion 17 can guide the airflow along a specific path, reduce eddies and airflow turbulence, thereby improving the overall flow efficiency.

[0043] To prevent airflow from leaking in the direction opposite to the outlet direction after entering the first cross-flow impeller 30 and / or the second cross-flow impeller 40, in some possible implementations, such as Figure 5 , Figure 6 As shown, the air supply assembly 1 includes a third backflow suppression device, which is disposed within the intermediate section 16. Both the first cross-flow impeller 30 and the second cross-flow impeller 40 are disposed within the intermediate section 16. By providing the third backflow suppression device within the intermediate section 16, backflow can be prevented from forming after the airflow enters the impeller, thus avoiding any impact on air supply efficiency due to backflow.

[0044] In some possible implementations, the third backflow suppression device includes a second protrusion 18, which protrudes toward the first cross-flow impeller 30 and the second cross-flow impeller 40. The second protrusion 18, protruding toward the first and second cross-flow impellers 30 and 40, can reduce the distance between the first and second cross-flow impellers 30 and the inner wall of the duct, thereby preventing or limiting the leakage of airflow after it enters the impellers, thus avoiding affecting the air supply efficiency.

[0045] In other embodiments provided in this disclosure, the first backflow suppression device, the second backflow suppression device and the third backflow suppression device mentioned above may also be structures such as air guide plates, air guide vanes, porous walls, vortex generators, etc. This disclosure does not limit them, as long as they can suppress the backflow of airflow in the flow channel.

[0046] In some possible implementations, such as Figure 5 , Figure 6As shown, the first guide section 14 of the first air duct 10 extends upward, and the first air outlet 11 is formed at the end of the first guide section 14. The second guide section 15 of the first air duct 10 extends downward at an angle, and the second air outlet 12 is formed at the end of the second guide section 15. In the first air duct 10, the first guide section 14 extends upward, and the first air outlet 11 is located at its end, which can send the air upward. The second guide section 15 extends downward at an angle, and the second air outlet 12 is located at its end, which can send the air downward at an angle. In this way, in the vertical direction, there is airflow coverage from top to bottom within a certain range, which greatly increases the air supply range in the vertical space compared to the traditional single-direction air supply.

[0047] The first guide section 14 of the second air duct 20 extends forward, with the third air outlet 21 formed at the end of the first guide section 14. The second guide section 15 of the second air duct 20 extends downward, with the fourth air outlet 22 formed at the end of the second guide section 15. Similarly, the first guide section 14 of the second air duct 20 extends forward, with the third air outlet 21 at the end, enabling forward horizontal airflow that can cover a relatively long distance. The second guide section 15 extends downward, with the fourth air outlet 22 delivering air downward, which can regulate the air in the area below. Through the combination of horizontal and vertical airflow, the coverage of the airflow is further expanded, making the air circulation in the entire indoor space more thorough.

[0048] To further increase the air supply range and the number of air outlets, in some possible implementations, a third air duct 50 may also be included within the air duct, such as... Figure 5 As shown, a fifth air outlet 51 and a sixth air outlet 52 are formed at both ends of the third air duct 50. The air supply assembly 1 also includes a third cross-flow impeller 70, which is disposed within the third air duct 50 and coaxially arranged with the first cross-flow impeller 30 and the second cross-flow impeller 40. The rotating shaft of the motor passes through and is connected to the first cross-flow impeller 30, the second cross-flow impeller 40, and the third cross-flow impeller 70 in sequence, and can drive the third cross-flow impeller 70 to rotate synchronously forward or in reverse with the first cross-flow impeller 30 and the second cross-flow impeller 40. By setting the third air duct 50, the third cross-flow impeller 70 disposed within the third air duct, and the fifth air outlet 51 and the sixth air outlet 52 formed at both ends of the third air duct 50, the air supply volume and air supply range of the air supply assembly 1 can be further increased, thereby achieving a better air supply effect.

[0049] Furthermore, the third cross-flow impeller 70 is disposed within the third air duct 50 and is coaxially arranged with the first cross-flow impeller 30 and the second cross-flow impeller 40. The rotating shaft of the motor passes through and is connected to the first cross-flow impeller 30, the second cross-flow impeller 40 and the third cross-flow impeller 70 in sequence. In this way, with only one motor, the first cross-flow impeller 30, the second cross-flow impeller 40 and the third cross-flow impeller 70 can be driven to rotate simultaneously, which simplifies the overall structure of the air supply assembly 1 and is more conducive to the miniaturization of the air supply assembly 1.

[0050] In some possible implementations, such as Figure 2 As shown, the bending direction of the blades 100 of the third cross-flow impeller 70 is the same as that of the blades 100 of the first cross-flow impeller 30. Since the motor drives the first cross-flow impeller 30 and the third cross-flow impeller 70 to rotate synchronously forward or in reverse, the consistent bending direction of the blades 100 enables the first cross-flow impeller 30 and the third cross-flow impeller 70 to work together better, allowing the airflow to propel the air through their respective ducts with the same efficiency and manner. This improves the overall working efficiency of the entire air supply assembly 1, making the air supply more stable and efficient.

[0051] Furthermore, similar airflow characteristics and cooperative working methods can reduce mutual interference between the first cross-flow impeller 30 and the third cross-flow impeller 70, as well as between the airflow and the duct wall, thereby reducing noise caused by airflow turbulence.

[0052] Regarding the embodiment mentioned above where the bending direction of the blades 100 of the third cross-flow impeller 70 is consistent with the bending direction of the blades 100 of the first cross-flow impeller 30, in this disclosure, as... Figure 2 As shown, the third cross-flow impeller 70 can also be positioned on the side of the second cross-flow impeller 40 away from the first cross-flow impeller 30. In this way, since the first cross-flow impeller 30 and the third cross-flow impeller 70 are respectively positioned on both sides of the second cross-flow impeller 40, and the bending direction of the blades 100 of the third cross-flow impeller 70 is consistent with the bending direction of the blades 100 of the first cross-flow impeller 30, during the synchronous rotation of the first cross-flow impeller 30, the second cross-flow impeller 40, and the third cross-flow impeller 70 driven by the motor can achieve synchronous air delivery, thereby increasing the air delivery efficiency and air delivery range of the air delivery assembly 1.

[0053] For example, in one embodiment provided in this disclosure, the first cross-flow impeller 30 can deliver air upward through the first air outlet 11, while the third cross-flow impeller 70 can deliver air upward through the fifth air outlet 51. In this way, when the motor starts, the first cross-flow impeller 30 and the third cross-flow impeller 70 can deliver air upward simultaneously, thereby enhancing the strength and range of upward (same direction) air delivery.

[0054] Alternatively, in another exemplary embodiment provided in this disclosure, the first cross-flow impeller 30 can deliver air upward through the first air outlet 11, while the third cross-flow impeller 70 can deliver air downward through the fifth air outlet 51. In this way, when the motor starts, the first cross-flow impeller 30 and the third cross-flow impeller 70 can deliver air upward and downward respectively, thereby increasing the air delivery range.

[0055] In some possible implementations, such as Figure 4 As shown, the flow area of ​​the third air duct 50 is equal to that of the first air duct 10. Since the flow area of ​​the third air duct 50 is equal to that of the first air duct 10, when the motor is running, the airflow delivered from both sides of the second air duct 20 can affect the surrounding environment in a similar manner and intensity, making the airflow distribution in the room more uniform and avoiding localized overheating or overcooling.

[0056] In some possible implementations, the third air duct 50 and the first air duct 10 are symmetrically arranged on both sides of the second air duct 20, and / or, the third cross-flow impeller 70 and the first cross-flow impeller 30 are symmetrically arranged on both sides of the second cross-flow impeller 40. On the one hand, when the motor drives the three cross-flow impellers to rotate synchronously in both directions, the symmetrical air duct structure makes the force on the entire air supply assembly 1 more balanced, reducing vibration and noise caused by unreasonable air duct layout; on the other hand, the symmetrical air outlet method can make the airflow distribution in the room more uniform, avoiding the phenomenon of local excessive or insufficient airflow, or excessively hot or cold temperatures.

[0057] In some possible implementations, such as Figure 1 , Figures 3-6 As shown, the air supply assembly 1 also includes a housing 80, which includes a top wall 81, a bottom wall 82, a side wall 83, and an inclined wall 84. The top wall 81 is connected to the side wall 83, and the lower end of the side wall 83 is connected to the bottom wall 82 through the inclined wall 84. The first air duct 10 and the second air duct 20 are both disposed inside the housing 80. An upper air vent 810 is formed on the top wall 81, which is connected to the first air vent 11. An inclined air vent 840 is formed on the inclined wall 84, which is arranged downwards and is connected to the second air vent 12. A front air vent 830 is formed on the side wall 83, which is connected to the third air vent 21. A lower air vent 820 is formed on the bottom wall 82, which is connected to the fourth air vent 22. In other words, air vents with different orientations are formed on different walls of the housing 80, which allows the air supply component 1 to cover a larger space. Users can choose different air vents for air supply according to actual needs, or open multiple air vents at the same time to achieve diversified air supply modes, thereby enhancing the applicability and flexibility of the product.

[0058] For example, when a user has a cooling need, the motor can rotate forward and drive the second cross-flow impeller 40 to rotate clockwise, so that the airflow is drawn in from the downwind vent 820 formed on the bottom wall 82 and blown out from the front vent 830 formed on the side wall 83. Because the cold air is denser, it slowly flows from top to bottom under its own gravity, covering the human body from top to bottom in the form of a shower breeze, reducing discomfort caused by direct airflow, improving the user's comfort, and forming a top-down air circulation in the room.

[0059] For example, when a user has a heating need, the motor can reverse and drive the first cross-flow impeller 30 and the third cross-flow impeller 70 to rotate counterclockwise, so that the airflow is drawn in from the upper air inlet 810 formed on the top wall 81 and blown out from the inclined air inlet 840 formed on the inclined wall 84. The hot air rises slowly and wraps around the human body from bottom to top in a carpet-like manner, improving the user's comfort.

[0060] A characteristic of a cross-flow impeller is that the airflow passes laterally through the impeller. If the blades 100 are a continuous full circle, an unfavorable boundary layer and vortices easily form at the tips of the blades 100 (on the side away from the axial centerline), leading to uneven airflow and reduced efficiency. Based on this, in some possible implementations, such as... Figure 2 As shown, both the first cross-flow impeller 30 and the second cross-flow impeller 40 include multiple sets of blades 100 arranged circumferentially, with adjacent sets of blades 100 spaced apart along their axial direction. The circumferentially arranged multiple sets of blades 100 allow the impeller to continuously interact with the air at different circumferential positions during rotation. As the impeller rotates, the blades 100 continuously cut the air, creating multiple airflow intake and exhaust zones, resulting in a more uniform airflow distribution within the duct and preventing localized areas of excessively strong or weak airflow. Furthermore, the axially spaced sets of blades 100 further increase the airflow area, allowing more air to be drawn in and exhausted from the duct per unit time, thereby effectively improving the ventilation volume and air exchange efficiency of the duct.

[0061] In addition, the axially spaced blades 100 can also disperse the peak pulsations caused by a single blade 100, reduce the vibration amplitude and related noise of a specific blade 100, and improve the stability of the blade 100 operation.

[0062] In addition, the air supply assembly 1 may also include a thermoelectric auxiliary (not shown), an evaporator (not shown), and a water collection tray (not shown). The partition plate can divide the space inside the housing 80 into the aforementioned cavity and the temperature regulating cavity. One of the first air outlet 11 and the second air outlet 12, as well as one of the third air outlet 21 and the fourth air outlet 22, are connected to the temperature regulating cavity. The thermoelectric auxiliary and the evaporator are disposed in the temperature regulating cavity and can heat or cool the temperature flowing through the temperature regulating cavity. The water collection tray is disposed at the bottom of the temperature regulating cavity for collecting condensate.
