Abstract
Description
Technical Field
[0001] This utility model relates to the field of air guiding device technology, and in particular to an outdoor air conditioning unit and an air conditioner having the same. Background Technology
[0002] In existing technology, during the operation of an air conditioner outdoor unit, when the refrigerant flows to the outdoor heat exchanger, heat is exchanged through the heat exchanger and then released into the outdoor environment through the air duct. During airflow, the airflow is driven by the fan and flows out through the air guide ring. In actual use, the gap between the fan blades and the air guide ring has a significant impact on the operation of the air conditioner outdoor unit. If the gap is too large, it will cause axial oblique flow, reducing the fan's air volume and efficiency. If the gap is too small, it will pose a higher safety hazard. Furthermore, a larger gap will increase the noise generated by the fan blades during operation, affecting the user experience. Utility Model Content
[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one objective of this utility model is to provide an outdoor air conditioner unit that, by adjusting the structure of the air guide ring, constructs multiple arc-shaped air guide sections on the air guide ring, so that the air guide ring can have good air guiding performance and a high air volume, while also reducing the rotational speed of the outdoor air conditioner unit, thereby reducing the operating noise of the outdoor air conditioner unit and improving the user experience.
[0004] Another objective of this utility model is to provide an outdoor air conditioner, wherein the outdoor air conditioner is provided with an outdoor air conditioning unit as shown above.
[0005] An outdoor unit of an air conditioner according to an embodiment of the present invention includes: an air duct, fan blades, and an air guide ring. One end of the air duct is disposed opposite to the outdoor heat exchanger, and the other end of the air duct is connected to the outdoor environment. The fan blades are disposed at the end of the air duct away from the outdoor heat exchanger. The air guide rings are disposed at the end of the air duct away from the outdoor heat exchanger, and the air guide rings are spaced apart on the outer side of the fan blades. The cross-section of the air guide ring along the air outlet direction includes a first air guide portion and a second air guide portion. The airflow passes through the second air guide portion and the first air guide portion and is then discharged from the outdoor unit of the air conditioner. The cross-sectional projection of the first air guide portion is an inclined straight line, and the cross-sectional projection of the second air guide portion is a plurality of sequentially connected arcs.
[0006] According to the embodiment of the present invention, the outdoor unit of the air conditioner is configured with a first air guide and a second air guide in sequence along the air outlet direction by setting the air guide ring at the end of the air duct as a first air guide and a second air guide. Since the cross section of the first air guide is set as an inclined straight line and the cross section of the second air guide is set as a continuous arc segment, the first air guide can better guide the airflow to the fan blade for driving circulation. The gap between the second air guide and the fan blade is relatively small, so that the gap between the air guide ring and the fan blade can ensure the safe operation of the outdoor unit of the air conditioner, while also increasing the air volume of the outdoor unit of the air conditioner, reducing the speed of the outdoor unit of the air conditioner, thereby reducing the operating noise of the outdoor unit of the air conditioner and improving the user experience.
[0007] In some embodiments, the second air guide includes: a first connecting section, a second connecting section, and a third connecting section, wherein one end of the first connecting section is connected to one end of the first air guide that is away from the air outlet direction; one end of the second connecting section is connected to the other end of the first connecting section; and one end of the third connecting section is connected to the other end of the second connecting section.
[0008] In some embodiments, by configuring the second air guide section as a multi-segment air guide section, the air guide ring can ensure the airflow guiding effect while also keeping the gap between the second air guide section and the fan blades relatively small. This achieves both improved performance and noise reduction of the outdoor unit. In some embodiments, the bending radius of the first connecting segment is A, the bending radius of the second connecting segment is B, and the bending radius of the third connecting segment is C. The bending radii A, B, and C satisfy the relationship: B≤A≤C.
[0009] In some embodiments, the bending radius A, the bending radius B, and the bending radius C also satisfy the following relationships: 85mm≤A≤93mm, 65mm≤B≤73mm, and 195mm≤C≤203mm.
[0010] In some embodiments, the curved surface design can reduce airflow resistance during circulation, thereby increasing the air volume delivered by the outdoor unit of the air conditioner. Similarly, the curved surface design can also reduce the gap between the air guide ring and the fan blades, allowing the airflow to be driven and circulated more effectively by the fan blades, improving the airflow circulation efficiency of the outdoor unit of the air conditioner, and reducing fan blade speed and ventilation noise.
[0011] In some embodiments, the vertical projection length of the first air guide is D, the vertical projection length of the second air guide is E, and the horizontal projection length of the air guide is F. The vertical projection length D, the vertical projection length E, and the horizontal projection length F satisfy the following relationship: 32mm≤D≤42mm, 62mm≤E≤72mm, 12mm≤F≤22mm.
[0012] In some embodiments, the length of the second air guide section is greater than that of the first air guide section, thereby giving the second air guide section a larger guiding range. This allows airflow to pass through the second air guide section more extensively, resulting in better guiding performance of the air guide ring during use. This ensures that the airflow is discharged as designed, thereby reducing noise generated during airflow. Furthermore, setting the width of the air guide section between 12mm and 22mm ensures that while the air guide section has good structural performance, it also guarantees sufficient clearance between it and the fan blades, significantly increasing the reliability of the outdoor unit of the air conditioner.
[0013] In some embodiments, the air guide ring further includes: a support rib, wherein there are multiple support ribs, including at least a first support rib and a second support rib, wherein the first support rib is supported on one side of the first air guide portion, the second support rib is spaced apart from the first support rib, and the second support rib is supported on one side of the second air guide portion.
[0014] In some embodiments, the supporting ribs include a first supporting rib and a second supporting rib. The first supporting rib is adapted to be disposed opposite to the first air guide ring to correspondingly improve the structural performance of the first air guide ring. Similarly, the second supporting rib is adapted to be disposed opposite to the second air guide ring to correspondingly improve the structural performance of the second air guide ring. In this way, during the construction of the air guide ring, the first and second supporting ribs are suitable for improving the structural strength of the air guide ring, so that the air guide ring can be arranged on the air duct for use as designed.
[0015] In some embodiments, the minimum distance between the edge of the fan blade and the inner wall of the air guide ring is H, and the minimum distance H satisfies the relationship: H≥9mm.
[0016] In some embodiments, the minimum distance between the edge of the fan blade and the inner wall of the air guide ring is greater than 9mm, which allows the outdoor unit of the air conditioner to have a high air volume while also allowing the fan blade to have a high rotation speed and relatively low noise.
[0017] In some embodiments, the fan blade diameter is J, the inner diameter of the air guide ring is K, and the diameter J and the diameter satisfy the following relationship: 580mm≤J≤590mm, 584mm≤K≤594mm.
[0018] In some embodiments, when assembling the fan blades and the air guide ring, not only can a gap be left to facilitate assembly, but also sufficient gap can be left between the edge of the assembled fan blades and the inner wall of the air guide ring to balance air volume and safety, and the noise is relatively low when the fan has a certain speed.
[0019] In some embodiments, the air guide ring is a one-piece molded part.
[0020] In some embodiments, by setting the air guide ring as an integrally formed structural component, the production steps of the air guide ring can be saved, the production process of the air guide ring can be simplified, and the connection strength between the first air guide part and the second air guide part can be improved, thereby increasing the structural strength of the air guide ring and enabling the air guide ring to be used as designed.
[0021] An air conditioner according to an embodiment of the present invention includes: an outdoor unit as described above.
[0022] According to the embodiment of the present invention, the air conditioner has an outdoor unit as shown above inside the outdoor unit. By sequentially arranging the air guide ring at the end of the air duct into a first air guide section and a second air guide section along the air outlet direction, and by setting the cross section of the first air guide section as an inclined straight line and the cross section of the second air guide section as a continuous arc segment, the first air guide section can better guide the airflow to the fan blades for driving circulation. The gap between the second air guide section and the fan blades is relatively small, so that the gap between the air guide ring and the fan blades can ensure the safe operation of the outdoor unit while also increasing the air volume of the outdoor unit, reducing the speed of the outdoor unit, thereby reducing the operating noise of the outdoor unit and improving the user experience.

[0036] Air conditioner outdoor unit 10,
[0037] Fan blade 100,

[0039] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.
[0040] The following is for reference. Figures 1-10 The outdoor unit 10 of the air conditioner according to an embodiment of the present utility model includes: an air duct, a fan blade 100, and an air guide ring 200.
[0041] Specifically, one end of the air duct is positioned opposite to the outdoor heat exchanger, and the other end of the air duct is connected to the outdoor environment; the fan blade 100 is located at the end of the air duct away from the outdoor heat exchanger; the air guide ring 200 is located at the end of the air duct away from the outdoor heat exchanger, and the air guide ring 200 is spaced apart on the outside of the fan blade 100; the cross-section of the air guide ring 200 along the air outlet direction includes a first air guide section 210 and a second air guide section 220, and the airflow is discharged from the outdoor unit 10 of the air conditioner after passing through the second air guide section 220 and the first air guide section 210; wherein, the cross-sectional projection of the first air guide section 210 is an inclined straight line, and the cross-sectional projection of the second air guide section 220 is a plurality of sequentially connected arcs.
[0042] It should be noted that during the use of the outdoor air conditioner, the system includes an air duct, fan blades 100, and air guide ring 200. During the heat exchange process of the outdoor heat exchanger of the outdoor air conditioner, heat is exchanged through the outdoor heat exchanger, and the exchanged airflow enters the air duct. After the airflow enters the air duct, the fan blades 100 inside the air duct rotate and drive the airflow to exchange heat with the outdoor heat exchanger, so that the airflow can enter the outdoor environment more quickly, thereby improving the working efficiency of the outdoor heat exchanger. During the process of the airflow entering the outdoor environment from the air duct, it passes through the air guide ring 200 and the grille located at the outer end of the air duct. The air guide ring 200 is used to restrict the air outlet position of the air duct and place the fan blades 100 at the air guide ring 200 so that the fan blades 100 can drive the airflow to exchange more efficiently during rotation. The grille located on the outside of the air guide ring 200 is used to prevent debris from entering the air duct and affecting the efficiency and performance of the air duct.
[0043] In actual use, the gap between the air guide ring 200 and the fan blade 100 has a crucial impact on the operation of the outdoor unit of the air conditioner. Specifically, if the gap between the fan blade 100 and the air guide ring 200 is too large, it will cause axial oblique flow, reducing the fan's air volume and operating efficiency. Conversely, if the gap is too small, it will pose a significant safety hazard. Furthermore, if there is a large gap between the air guide ring 200 and the fan blade 100, the fan blade 100's rotational speed will be increased to ensure sufficient airflow, resulting in higher noise levels during operation.
[0044] Therefore, this application provides an outdoor air conditioner unit 10 for an outdoor air conditioner unit. By optimizing the structure of the air guide ring 200, the gap between the air guide ring 200 and the fan blade 100 is relatively good to reduce noise, while also leaving enough space for the fan blade 100 to rotate, so that the fan blade 100 can achieve more efficient airflow at a relatively low speed, thereby improving the heat exchange efficiency of the outdoor air conditioner unit and reducing operating noise.
[0045] Specifically, a first air guide section 210 and a second air guide section 220 are provided in the air outlet direction of the air guide ring 200. The first air guide section 210 and the second air guide section 220 are adapted to guide the exchange and output of airflow. During the flow process, the airflow is adapted to pass through the first air guide section 210 and the second air guide section 220 in sequence and then be agitated by the fan blades 100 to be discharged from the outdoor unit of the air conditioner. In a specific embodiment, the cross-sectional projection of the first air guide section 210 is set as an inclined straight line, while the cross-sectional projection of the second air guide section 220 is set as a continuous arc. During the airflow process, the first air guide section 210 is adapted to guide the airflow output so that the airflow can be guided by the fan blades 100, so that the airflow can be driven and guided by the fan blades 100 better, so that the outdoor unit of the air conditioner has good performance and relatively low operating noise.
[0046] According to an embodiment of the present invention, an outdoor air conditioner 10 for an outdoor air conditioner unit has an air guide ring 200 at the end of the air duct that is sequentially configured as a first air guide 210 and a second air guide 220 along the air outlet direction. Since the cross-section of the first air guide 210 is set as an inclined straight line and the cross-section of the second air guide 220 is set as a continuous arc segment, the first air guide 210 can better guide the airflow to the fan blade 100 for driving circulation. The gap between the second air guide 220 and the fan blade 100 is relatively small, so that the gap between the air guide ring 200 and the fan blade 100 can ensure the safe operation of the outdoor air conditioner unit, while also increasing the air volume of the outdoor air conditioner unit, reducing the speed of the outdoor air conditioner unit, thereby reducing the operating noise of the outdoor air conditioner unit and improving the user experience.
[0047] In some embodiments, the second air guide 220 includes a first connecting section 221, a second connecting section 222, and a third connecting section 223. One end of the first connecting section 221 is connected to the end of the first air guide 210 that is away from the air outlet direction; one end of the second connecting section 222 is connected to the other end of the first connecting section 221; and one end of the third connecting section 223 is connected to the other end of the second connecting section 222.
[0048] In other words, during the construction of the second air guide section 220, it sequentially includes a first connecting section 221, a second connecting section 222, and a third connecting section 223 along the air outlet direction. During airflow, the air passes through the first connecting section 221, the second connecting section 222, and the third connecting section 223 in sequence before exiting the air duct. In this application, by setting the second air guide section 220 as a multi-segment air guide section, the air guide ring 200 can ensure the air outlet guiding effect while also keeping the gap between the second air guide section 220 and the fan blade 100 relatively small, thereby improving the performance of the outdoor unit of the air conditioner while also reducing the noise of the outdoor unit.
[0049] In some embodiments, the bending radius of the first connecting segment 221 is A, the bending radius of the second connecting segment 222 is B, and the bending radius of the third connecting segment 223 is C. The bending radii A, B, and C satisfy the relationship: B≤A≤C.
[0050] It should be noted that the bending radius A of the first connecting section 221, the bending radius B of the second connecting section 222, and the bending radius C of the third connecting section 223 are related to the airflow of the second air guide section 220. The airflow is suitable for passing over the outer surfaces of the first connecting section 221, the second connecting section 222, and the third connecting section 223, and then flowing out for heat exchange after being driven by the fan blades 100, making the heat exchange process of the outdoor unit of the air conditioner more efficient. Furthermore, the curved surface design reduces airflow resistance during circulation, thereby increasing the air volume delivered by the outdoor unit. Similarly, the curved surface design also allows for a smaller gap between the air guide ring 200 and the fan blades 100, enabling better airflow through the fan blades 100, improving the airflow circulation efficiency of the outdoor unit, and reducing the fan blade speed and ventilation noise.
[0051] Furthermore, the relationship between the aforementioned bending radius A, bending radius B, and bending radius C is set such that bending radius A is greater than or equal to bending radius B, and bending radius C is greater than or equal to bending radius A. This allows the second connecting section 222 to protrude more during airflow, enabling the air guide ring 200 to be closer to the fan blade 100, and the gap between the air guide ring 200 and the fan blade 100 to be smaller, thereby increasing the air volume driven by the fan blade 100 and improving the operating efficiency of the outdoor unit of the air conditioner.
[0052] In some specific embodiments, the bending radii A, B, and C also satisfy the following relationships: 85mm ≤ A ≤ 93mm, 65mm ≤ B ≤ 73mm, and 195mm ≤ C ≤ 203mm. That is, in some specific embodiments, the three arc segments are arranged according to the airflow direction. To make the construction and production of these arcs relatively simple and to ensure high structural strength to meet subsequent production requirements, the bending radii A, B, and C are arranged as follows: 85mm ≤ A ≤ 93mm, 65mm ≤ B ≤ 73mm, and 195mm ≤ C ≤ 203mm. In some more specific embodiments, it is suitable to set the bending radius A to 89mm, the bending radius B to 69mm, and the bending radius C to 199mm.
[0053] In some embodiments, the vertical projection length of the first air guide 210 is D, the vertical projection length of the second air guide 220 is E, and the horizontal projection length of the air guide is F. The vertical projection lengths D, E, and F satisfy the following relationships: 32mm≤D≤42mm, 62mm≤E≤72mm, and 12mm≤F≤22mm. It is understood that during the arrangement of the air guides, it is suitable to construct the length of the first air guide 210 between 32mm and 42mm, and the length of the second air guide 220 between 62mm and 72mm, so that the length of the second air guide 220 is greater than the length of the first air guide 210. This allows the second air guide 220 to have a larger air guiding range, enabling more airflow to pass through the second air guide 220. This ensures that the air guide ring 200 has better guiding performance during use, allowing the airflow to be discharged as designed, thereby reducing noise generated during airflow. Furthermore, the width of the air guide is set between 12mm and 22mm to ensure that the air guide has good structural performance while also leaving sufficient clearance between it and the fan blade 100, which greatly increases the reliability of the outdoor unit 10 of the air conditioner.
[0054] In some embodiments, the air guide ring 200 further includes: support ribs 230, wherein there are multiple support ribs 230, including at least a first support rib 231 and a second support rib 232. The first support rib 231 is supported on one side of the first air guide portion 210, and the second support rib 232 is spaced apart from the first support rib 231 and is supported on one side of the second air guide portion 220. It is understood that during the construction of the air guide ring 200, support ribs 230 are also provided. The support ribs 230 are suitable for supporting the structure of the air guide ring 200, so that the arrangement of the air guide ring 200 at the air duct port is more reliable, thereby improving the reliability of the air guide ring 200 in use. Specifically, the support rib 230 includes a first support rib 231 and a second support rib 232. The first support rib 231 is adapted to be positioned opposite to the first air guide ring 200 to improve the structural performance of the first air guide ring 200. Similarly, the second support rib 232 is adapted to be positioned opposite to the second air guide ring 200 to improve the structural performance of the second air guide ring 200. In this way, during the construction of the air guide ring 200, the first support rib 231 and the second support rib 232 can effectively improve the structural strength of the air guide ring 200, allowing the air guide ring 200 to be arranged on the air duct as designed for use.
[0055] In some embodiments, the minimum distance between the edge of the fan blade 100 and the inner wall of the air guide ring 200 is H, and the minimum distance H satisfies the relationship: H≥9mm. It is understood that the minimum distance between the edge of the fan blade 100 and the inner wall of the air guide ring 200 is closely related to the airflow and noise. The closer the distance between the edge of the fan blade 100 and the inner wall of the air guide ring 200, the higher the airflow, but the greater the safety risk, and therefore the lower the fan speed. Conversely, the farther the distance between the edge of the fan blade 100 and the inner wall of the air guide ring 200, the higher the speed, but the greater the noise and the lower the airflow. Therefore, setting the minimum distance between the edge of the fan blade 100 and the inner wall of the air guide ring 200 to be greater than 9mm allows the outdoor unit 10 of the air conditioner to have a high airflow while also allowing the fan blade 100 to have a high speed and relatively low noise.
[0056] In some embodiments, the diameter of the fan blade 100 is J, and the inner diameter of the guide ring 200 is K. The diameters J and K satisfy the following relationships: 580mm ≤ J ≤ 590mm, 584mm ≤ K ≤ 594mm. It is understood that this is to ensure a sufficient gap between the fan blade 100 and the guide ring 200, thus defining the structure of both components. Specifically, the diameter of the fan blade 100 is set between 580mm and 590mm, and the inner diameter of the guide ring 200 is set between 584mm and 594mm. This ensures that during assembly, a gap is provided for easy assembly, and that the assembled fan blade 100 has a sufficient gap between its edge and the inner wall of the guide ring 200 to balance airflow and safety, while also resulting in relatively low noise levels when the fan operates at a certain speed.
[0057] In some embodiments, the air guide ring 200 is a one-piece molded part. By making the air guide ring 200 a one-piece molded structural part, the production steps of the air guide ring 200 can be saved, the production process of the air guide ring 200 can be simplified, and the connection strength between the first air guide part 210 and the second air guide part 220 can be improved, thereby increasing the structural strength of the air guide ring 200 and enabling the air guide ring 200 to be used as designed.
[0058] An air conditioner according to an embodiment of the present invention includes an outdoor unit 10 as described above. That is, the outdoor unit is adapted to include the outdoor unit 10 as described above, and the outdoor unit 10 is adapted to also include a base and an indoor heat exchanger. The base is adapted to have a receiving space to facilitate the assembly of the outdoor heat exchanger and the outdoor unit 10, and to protect the outdoor heat exchanger and the outdoor unit 10. Furthermore, by arranging the outdoor unit 10 opposite to the outdoor heat exchanger, the outdoor heat exchanger is adapted to exchange heat through the outdoor unit 10 during heat exchange, thereby improving the performance of the outdoor unit.
[0059] It should be noted that during the use of the outdoor unit 10 of the air conditioner, the system includes an air duct, fan blades 100, and air guide ring 200. During the heat exchange process of the outdoor heat exchanger of the outdoor air conditioner, heat is exchanged through the outdoor heat exchanger, and the exchanged airflow enters the air duct. After the airflow enters the air duct, the fan blades 100 in the air duct rotate and drive the airflow to exchange heat with the outdoor heat exchanger, so that the airflow can enter the outdoor environment more quickly, thereby improving the working efficiency of the outdoor heat exchanger. During the process of the airflow entering the outdoor environment from the air duct, it passes through the air guide ring 200 and the grille located at the outer end of the air duct. The air guide ring 200 is used to restrict the air outlet position of the air duct and to place the fan blades 100 at the air guide ring 200 so that the fan blades 100 can drive the airflow to exchange more efficiently during rotation. The grille located on the outside of the air guide ring 200 is used to prevent debris from entering the air duct and affecting the efficiency and performance of the air duct.
[0060] In actual use, the gap between the air guide ring 200 and the fan blades 100 has a crucial impact on the operation of the outdoor unit of the air conditioner. Specifically, if the gap between the fan blades 100 and the air guide ring 200 is too large, it will cause axial oblique flow, reducing the fan's air volume and operating efficiency. Conversely, if the gap is too small, it will pose a significant safety hazard. Furthermore, a larger gap will also increase the noise generated by the fan blades 100 during operation.
[0061] Thus, since the outdoor unit 10 of the air conditioner is provided inside the outdoor unit, the air guide ring 200 at the end of the air duct is arranged in sequence as a first air guide 210 and a second air guide 220 along the air outlet direction. Since the cross section of the first air guide 210 is set as an inclined straight line and the cross section of the second air guide 220 is set as a continuous arc segment, the first air guide 210 can better guide the airflow to the fan blade 100 for driving circulation. The gap between the second air guide 220 and the fan blade 100 is relatively small, so that the gap between the air guide ring 200 and the fan blade 100 can ensure the safe operation of the outdoor unit of the air conditioner, while also increasing the air volume of the outdoor unit of the air conditioner, reducing the speed of the outdoor unit of the air conditioner, thereby reducing the operating noise of the outdoor unit of the air conditioner and improving the user experience.
