Description

Technical Field

[0001] This utility model relates to the field of air handling equipment technology, and in particular to an air guide ring, a fan, and an air conditioner. Background Technology

[0002] In existing technologies, the outdoor unit of an air conditioner includes a panel, an air guide ring, a fan wheel, a drive motor that drives the fan wheel, and a motor bracket for mounting the drive motor. Generally, the motor bracket is mounted on the panel, and the air guide ring is also mounted on the panel. The motor bracket includes a mounting part and a support member. To ensure airflow, the support member is strip-shaped. In addition, to ensure the structural strength of the support member, a flange is provided along its extended length. The flange creates an assembly gap at the connection between the air guide ring and the motor bracket. The high-speed rotating fan wheel forces gas into the assembly gap, causing a significant change in airflow velocity after passing through the assembly gap, resulting in relatively high noise at that location.

[0063] Please see Figure 14 and Figure 15 The outdoor unit of the air conditioner includes a panel 2, an air guide ring 1, a fan wheel, a drive motor that drives the fan wheel, and a motor bracket 3 for mounting the drive motor. Generally, the motor bracket 3 is set on the panel 2, and the air guide ring 1 is also set on the panel 2. The motor bracket 3 includes a mounting part and a support member 5. In order to ensure the air volume, the support member 5 is set in a strip shape. In addition, in order to ensure the structural strength of the support member 5, the support member 5 is provided with a flange 52 along its extended length. The flange 52 creates an assembly gap 6 at the connection between the air guide ring 1 and the motor bracket 3. The high-speed rotating fan wheel fills the assembly gap 6 with gas. Since the flow area of ​​the assembly gap 6 is relatively small, the airflow velocity after flowing through the assembly gap 6 changes greatly, resulting in a large noise at this point.

[0064] This utility model proposes an air guide ring 1, which can be applied to a standalone fan or to an air conditioner with a fan, aiming to reduce noise at the connection between the air guide ring 20 and the motor bracket 3. For ease of understanding and explanation, the following is attached to the specification of this utility model. Figures 1 to 15 In the diagram, the solid arrow indicates a surface, groove, or hole.

[0065] The air conditioner can be a window air conditioner, a split-type air conditioner, or a cabinet-type air conditioner. If the air conditioner is a split-type air conditioner, the air guide ring 1 is located on the outdoor unit of the split-type air conditioner (hereinafter referred to as the outdoor unit of the air conditioner). The following explanation will be based on the example of the air guide ring 1 being installed on the outdoor unit of a split-type air conditioner.

[0066] Please see Figures 1 to 13 In an embodiment of this utility model, the outdoor unit of the air conditioner includes a fan and an air guide ring 1. The fan includes a motor bracket 3. The motor bracket 3 includes a mounting component 4 for mounting a drive motor and a support component 5 disposed on the mounting component 4 and used to connect the air guide ring 1. The air guide ring 1 includes an air guide ring 20 and a mounting base 10 disposed on the air guide ring 20 and integrally formed with the air guide ring 20. The mounting base 10 has a slot 21 on the leeward side for the support component 5 to be inserted.

[0067] The fan includes a wind turbine and a drive motor. The drive motor is mounted on the mounting component 4 and drives the wind turbine. The wind turbine is usually an axial flow wind turbine. The motor bracket 3 includes a mounting component 4 for mounting the drive motor and a support component 5 located on the mounting component 4 for connecting the air guide ring 1. There are usually multiple support components 5, which are arranged radially at intervals along the circumference of the mounting component 4.

[0068] In this embodiment, the air guide ring 20 mainly serves a supporting function, providing a stable support surface through its annular structure. The air guide ring 20 can have many shapes. Taking the axis of the air guide ring 20 as an auxiliary plane, the shape of the figure intercepted by the auxiliary plane on the air guide ring 20 can be a regular shape such as a circle or an ellipse, or other irregular shapes. Examples will not be given here.

[0069] The mounting base 10 is disposed on the air guide ring 20 and integrally formed with the air guide ring 20. The mounting base 10 has a slot 21 on its leeward side for inserting the support member 5. In this way, by integrating the mounting base 10 with the air guide ring 20 and providing a slot 21 on the leeward side for inserting the support member 5, the mounting base 10 covers the installation gap 6 between the support member 5 and the air guide ring 20, preventing airflow from directly entering through the installation gap 6 and reducing the thickness of the boundary layer at that point, thereby reducing the noise at the connection between the motor bracket 3 and the air guide ring 20.

[0070] There are many ways to integrate the air guide ring 20 and the mounting base 10. Here are some common methods: First, use injection molding to integrally form the air guide ring 20 and the mounting base 10. Injection molding is suitable for plastics and composite materials, and by controlling the molding process with a mold, it can achieve complex geometric shapes and high dimensional accuracy. Second, achieve this through secondary injection molding (in-mold assembly). Third, manufacture the air guide ring 20 and the mounting base 10 separately, then firmly connect the two parts together using welding technology, or use high-strength adhesives to bond the air guide ring 20 and the mounting base 10 together, etc.

[0071] It should be understood that in this embodiment, the mounting base 10 and the air guide ring 20 are integrally set, which means that there is no air gap 6 between the connecting surfaces of the two.

[0072] The technical solution of this utility model is to set a mounting base 10 on the air guide ring 20. The mounting base 10 is integrally set with the air guide ring 20. The mounting base 10 has a slot 21 on the leeward side for the support member 5 to be inserted. The setting of the mounting base 10 covers the installation gap 6 between the support member 5 and the air guide ring 20, so that the airflow cannot be directly poured in from the installation gap 6, and the thickness of the boundary layer at this point is also reduced, thereby reducing the noise at the connection between the motor bracket 3 and the air guide ring 20.

[0073] Furthermore, the mounting base 10 has a windward surface 101 and a leeward surface. The windward surface 101 of the mounting base 10 is provided with the slot 21. In a preferred embodiment, in order to further reduce the thickness of the boundary layer at this location, thereby reducing the noise at the connection between the motor bracket 3 and the air guide ring 20, the windward surface 101 of the mounting base 10 is provided with a convex arc surface.

[0074] Furthermore, the mounting base 10 has multiple blind holes 102 on its windward surface 101. Blind holes 102 are non-through holes, and these holes are spaced apart on the windward surface 101. The blind holes 102 can be arranged in a regular array or other regular pattern, or they can be randomly arranged. The blind holes 102 can be cylindrical or hemispherical, preferably hemispherical. Thus, the arrangement of the blind holes 102 creates an uneven surface on the windward surface 101 of the mounting base 10. This uneven surface breaks the airflow into small vortices, suppressing excessive boundary layer development (reducing the thickness of the boundary layer at that point), preventing the formation of large vortices, and thereby reducing vortex shedding noise.

[0075] In one embodiment, the support member 5 includes a support body 51 and two flanges 52, the two flanges 52 being disposed on both sides of the support body 51 along its length extension direction; the mounting base 10 has a first end and a second end disposed opposite to each other, the second end being connected to the air guide ring 20; the slot 21 includes two sub-slots 21a for inserting the two flanges 52, the two sub-slots 21a extending from the second end along the first end, and the distance between the two sub-slots 21a gradually increasing from the first end toward the second end.

[0076] In this embodiment, since flanges 52 are provided on both sides of the support member 5 along its length extension direction, the structural strength of the support member 5 itself is improved. Furthermore, since the two flanges 52 of the support member 5 are inserted into the two sub-slots 21a, the stability of the connection between the air guide ring 1 and the motor bracket 3 can be further improved. The slots 21 and the flanges 52 are adaptively connected. The gradually expanding sub-slots 21a can help the flanges 52 self-position, ensuring that the flanges 52 maintain the correct direction and position when inserted into place, thereby improving the assembly accuracy of the entire support member 5. Preferably, both sub-slots 21a are arc-shaped grooves.

[0077] Generally, the number of mounting bases 10 is adapted to the number of support members 5. To ensure the stability of the drive motor installation, there are usually multiple support members 5, and therefore multiple mounting bases 10. These multiple mounting bases 10 are arranged at intervals along the inner circumference of the air guide ring 20. For example, the number of mounting bases 10 can be three, four, five, or more. Taking five mounting bases 10 as an example, since the air guide ring 1 and the mounting bracket are aligned and installed along the axial direction of the air guide ring 1, there must be a certain installation gap between the groove wall of the slot 21 and the flange 52 of the support member 5 after installation. This ensures that multiple support members 5 can be simultaneously inserted into the slot 21.

[0078] Based on this, please refer to Figures 1 to 9 In one embodiment, the mounting base 10 includes a base body 100, two bent portions 200, and several protrusions 300. The two bent portions 200 are located on opposite sides of the base body 100, and the several protrusions 300 are located on the base body 100 and between the two bent portions 200. One bent portion 200 and the several protrusions form a sub-slot 21a, and the several protrusions form a dissipation cavity 301, which communicates with the two sub-slots 21a respectively. Thus, the technical solution of this embodiment, by setting a dissipation area within the protrusions, which can be the dissipation cavity 301 in this embodiment, allows the turbulent kinetic energy of the airflow to be attenuated and dissipated within the dissipation cavity 301 after the airflow enters it, thereby reducing the noise at the connection between the air guide ring 20 and the support member 5.

[0079] In one exemplary embodiment, please refer to Figure 5 The plurality of protrusions include a first protrusion 310 and a second protrusion 320. The first protrusion 310 is disposed at a first end of the seat body 100, and the second protrusion 320 is disposed at a second end of the seat body 100. The first protrusion 310 includes a first protrusion sub-part 311 and two first air guides 312 disposed on opposite sides of the first protrusion sub-part 311. The second protrusion 320 includes a second protrusion sub-part 321 and two second air guides 322 disposed on opposite sides of the second protrusion sub-part 321. In the direction from the first end to the second end, the two first air guides 312 and the two second air guides 322 are located between the first protrusion sub-part 311 and the second protrusion sub-part 321.

[0080] In this embodiment, the first protrusion 311 and the second protrusion 320 abut against the support body 51. In the direction from the first end to the second end, two first air guides 312 and two second air guides 322 are located between the first protrusion 311 and the second protrusion 321. That is, the first protrusion 311, one first air guide 312, one second air guide 322, the second protrusion 321, another second air guide 322 and another first air guide 312 are arranged in sequence along a circumference to form a dissipation cavity 301. There is a gap between the first air guide 312 and the second air guide 322 so that the airflow can enter the dissipation cavity 301 from the sub-slot 21a. The setting of the dissipation cavity 301 can reduce the airflow velocity at this location, causing its turbulent kinetic energy to attenuate and dissipate, and reducing the noise at the connection between the air guide ring 20 and the support member 5.

[0081] For further information, please refer to [link / reference]. Figure 5 To facilitate airflow into the dissipation cavity 301, at least one of the first air guide sections 312 is provided with a first air guide slope 313. The first air guide slope 313 is located on the side of the first air guide section 312 away from the dissipation cavity 301, and is inclined from its connection with the first protrusion sub-section 311 toward the second protrusion sub-section 321. Alternatively, one of the two first air guide sections 312 may have a first air guide slope 313, or both first air guide sections 312 may have a first air guide slope 313. Preferably, both first air guide sections 312 have a first air guide slope 313, which improves the stability of the airflow velocity at the mounting base 10.

[0082] It is worth mentioning that the inclination angle of the first air guide slope 313 is not less than 30° and not greater than 60°, wherein the inclination angle of the first air guide slope 313 is as follows: Figure 5As shown in α1, the tilt angle of the first guide slope 313 can be, but is not limited to, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59° or 60°.

[0083] In one exemplary embodiment, please refer to Figure 7 Each of the two first air guide sections 312 is provided with a first air guide slope 313, which is located on the side of the first air guide section 312 away from the dissipation cavity 301. The first air guide slope 313 is inclined from its connection with the first protrusion sub-section 311 toward the second protrusion sub-section 321. Each of the two second air guide sections 322 is provided with a second air guide slope 324 and a first inner wall surface 323. The second air guide slope 324 is located on the side of the second air guide section 322 away from the second protrusion sub-section 321. The third air guide slope 331 is inclined towards the first protruding sub-part 311 from its connection with the first inner wall surface 323; the two second air guide parts 322 are provided with a first dissipation groove 326 on the side where the first inner wall surface 323 is located, and the first dissipation groove 326 is connected to the dissipation cavity 301; the second air guide part 322 also has a first outer wall surface 325, and the second air guide part 322 is provided with a second dissipation groove 327 on the side where the first outer wall surface 325 is located, and the second dissipation groove 327 is connected to the sub-slot 21a.

[0084] Thus, the airflow will flow along the flange 52. When it enters the front part of the dissipation region (that is, before entering the dissipation cavity 301), due to the setting of the first guide slope 313, the second guide slope 324, the first dissipation groove 326 and the second dissipation groove 327, the airflow will flow inward due to the sudden increase in the inlet, and then flow towards the vortex dissipation cavity 301, further attenuating and dissipating the turbulent kinetic energy of the airflow, and further reducing the noise at the connection between the guide ring 20 and the support member 5.

[0085] Please refer to further reading Figure 5At least one of the second air guide portions 322 is provided with a second air guide slope 324 and a first inner wall surface 323. The second air guide slope 324 is located on the side of the second air guide portion 322 away from the second protruding sub-part 321. The third air guide slope 331 is inclined towards the first protruding sub-part 311 from its connection with the first inner wall surface 323. Similar to the previous embodiment, one of the two second air guide portions 322 is provided with a second air guide slope 324, or both second air guide portions 322 are provided with a second air guide slope 324. Preferably, both second air guide portions 322 are provided with a second air guide slope 324, which can also improve the stability of the airflow velocity at that location on the mounting base 10.

[0086] It should be understood that the inclination angle of the second guide slope 324 is as follows: Figure 5 As shown in α2', in practice, for ease of measurement, it is represented by its interior alternate angle α2.

[0087] It is worth mentioning that, in order for the second guide slope 324 to have a better airflow guiding effect, the inclination angle of the second guide slope 324 is not less than 15° and not greater than 75°. The inclination angle of the second guide slope 324 can take values ​​including, but not limited to, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, and 34°. 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, 70°, 71°, 72°, 73°, 74°, or 75°.

[0088] Based on any of the above embodiments, please refer to Figure 8 and Figure 9 At least one of the second air guides 322 is provided with a first dissipation groove 326 on the side where the first inner wall surface 323 is located, and the first dissipation groove 326 is connected to the dissipation cavity 301.

[0089] It is understood that this embodiment is the same as the previous two embodiments. Since the second protrusion 320 has two second air guides 322, in this solution, either of the two second air guides 322 may have a first dissipation groove 326 on the side where its first inner wall surface 323 is located, or both second air guides 322 may have a first dissipation groove 326 on the side where its first inner wall surface 323 is located. Preferably, both second air guides 322 may have a first dissipation groove 326 on the side where their first inner wall surface 323 is located, which can also improve the stability of the airflow velocity of the mounting base 10 at that location.

[0090] In another embodiment, please refer to Figures 7 to 9 The second air guide 322 also has a first outer wall surface 325, and at least one second air guide 322 is provided with a second dissipation groove 327 on the side where the first outer wall surface 325 is located. The second dissipation groove 327 is connected to the sub-slot 21a.

[0091] It is understood that this embodiment is the same as the previous two embodiments. Since the second protrusion 320 has two second air guides 322, in this solution, either of the two second air guides 322 may have a second dissipation groove 327 on the side where its first outer wall surface 325 is located, or both second air guides 322 may have a second dissipation groove 327 on the side where its first outer wall surface 325 is located. Preferably, both second air guides 322 may have a second dissipation groove 327 on the side where their first outer wall surface 325 is located, which can also improve the stability of the airflow velocity of the mounting base 10 at this location.

[0092] Based on any of the above embodiments, please refer to Figures 6 to 9 The protrusions further include a third protrusion 330, which is disposed between the first air guide 312 and the second air guide 322. The third protrusion 330 has a second inner wall surface 332, a third air guide inclined surface 331, and a second outer wall surface 333 connected in sequence. The third air guide inclined surface 331 is located on the side of the third protrusion 330 facing the first protrusion sub-part 311. The third air guide inclined surface 331 is inclined towards the first protrusion sub-part 311 from its connection with the second inner wall surface 332. The third protrusion 330 forms a third dissipation groove 334 on the second outer wall surface 333. The third dissipation groove 334 communicates with the sub-slot 21a.

[0093] In this embodiment, the arrangement of the first protrusion 310, the second protrusion 320, and the third protrusion 330 ensures that some airflow undergoes at least three layers of attenuation before entering the dissipation cavity 301. This significantly reduces the airflow velocity and pressure at the connection between the support member 5 and the air guide ring 20. Consequently, the pressure difference between the connection between the support member 5 and the air guide ring 20 on the inner side of the air guide ring 20 and the connection between the support member 5 and the air guide ring 20 on the outer side of the air guide ring 20 is not significant. Since the airflow flows from the high-pressure area to the low-pressure area, this reduces the noise generated by the sudden drop in airflow velocity at the connection between the support member 5 and the air guide ring 20.

[0094] Preferably, please refer to Figure 7 The number of the third protrusions 330 is multiple, and the multiple third protrusions 330 are spaced apart along the extension direction of the sub-slot 21a. In this embodiment, by adding the third protrusions 330, the attenuation level of some airflow can be increased, thereby further reducing the air pressure difference at the connection between the support member 5 and the air guide ring 20 on the inner side of the air guide ring 20 and the connection between the support member 5 and the air guide ring 20 on the outer side of the air guide ring 20. The noise generated by the sudden drop in airflow velocity at the connection between the support member 5 and the air guide ring 20 is not large, thereby further reducing the noise generated by the sudden drop in airflow velocity at the connection between the support member 5 and the air guide ring 20.

[0095] It is worth mentioning that the inclination angle of the third guide slope 331 is not less than 15° and not greater than 75°. Specifically, it has the same inclination angle as the second guide slope 324. This inclination angle is provided for ease of measurement. Figure 6 α3 shown is the interior offset angle of the inclination angle of the third guide slope 331. The inclination angle of the third guide slope 331 can take values ​​including, but not limited to, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, and 41°. 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, 70°, 71°, 72°, 73°, 74° or 75°.

[0096] Based on any of the above embodiments, in order to improve the dissipation effect of the dissipation cavity 301 on the airflow and thereby further reduce the airflow velocity in the dissipation cavity 301, the mounting base 10 further includes a fourth protrusion 340, which is disposed in the dissipation cavity 301.

[0097] The fourth protrusion 340 can have various shapes and structures, such as cylindrical, conical, frustum-shaped, or pyramidal, etc. For example, please refer to [reference needed]. Figure 9 The fourth protrusion 340 is elongated and extends from the first end of the mounting base 10 toward the second end.

[0098] Furthermore, there are multiple fourth protrusions 340, and the multiple fourth protrusions 340 are arranged at intervals within the dissipation cavity 301.

[0099] This utility model also proposes a fan, which includes a motor bracket 3 and an air guide ring 1. The specific structure of the air guide ring 1 is as described in the above embodiments. Since this fan adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0100] In one embodiment, the fan includes a wind turbine, a drive motor, a motor bracket 3, and a wind guide ring 1 as described in any of the preceding embodiments. The drive motor drives and connects to the wind turbine. The motor bracket 3 includes a mounting member 4 for mounting the drive motor and a support member 5 disposed on the mounting member 4 for connecting the wind guide ring 1. The wind guide ring 1 includes a wind guide ring 20 and a mounting base 10. The wind guide ring 20 is mounted on the panel 2. The mounting base 10 is disposed on the wind guide ring 20 and integrally formed with the wind guide ring 20. The mounting base 10 has a slot 21 on its leeward side for the support member 5 to be inserted.

[0101] This utility model also proposes an air conditioner, which includes a panel 2 and the aforementioned fan. The fan includes a motor bracket 3 and an air guide ring 1. The specific structure of the air guide ring 1 is as described in the above embodiments. Since this fan adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The air conditioner can be a window air conditioner, a split-type air conditioner, or a cabinet-type air conditioner. If the air conditioner is a split-type air conditioner, the air guide ring 1 is located on the outdoor unit of the split-type air conditioner.

[0102] In one embodiment, the air conditioner includes an indoor unit and an outdoor unit. The outdoor unit includes a panel 2, and a motor bracket 3 is mounted on the panel 2. Alternatively, the motor bracket 3 is integrally formed with the panel 2. The panel 2 has an air outlet, and the motor bracket 3 is located at the air outlet.

[0103] The technical solution of this utility model is to set a mounting base 10 on the air guide ring 20. The mounting base 10 is integrally set with the air guide ring 20. The mounting base 10 has a slot 21 on the leeward side for the support member 5 to be inserted. The setting of the mounting base 10 covers the installation gap between the support member 5 and the air guide ring 20, so that the airflow cannot be directly poured in from the installation gap, and also reduces the thickness of the boundary layer at that time, thereby reducing the noise at the connection between the motor bracket 3 and the air guide ring 20.
