The guide ring guides the airflow generated when the fan rotates forward. When the fan is a reversible axial flow fan, the guide ring cannot guide the airflow generated when the fan rotates in reverse, so this problem needs to be addressed. Utility Model Content

[0006] The motor bracket is used to support the motor of the fan; the guide ring is disposed on the motor bracket and is used to be sleeved on the outside of the fan blades. One end of the guide ring has a first guide portion, which is used to guide the air generated when the fan rotates forward; the other end of the guide ring has a second guide portion, which is used to guide the air generated when the fan rotates in reverse.

[0007] In some embodiments, the end of the first guide portion has a first flare, through which the first guide portion guides the air generated when the fan rotates forward;

[0008] And / or, the end of the second guide portion has a second flare, through which the second guide portion guides the air generated when the fan reverses.

[0009] In some embodiments, the guide ring is integrally formed on the motor bracket.

[0010] In some embodiments, the motor bracket includes a support base and a connecting beam connected to the support base, the motor bracket providing support for the motor through the support base; the support base is connected to the guide ring through the connecting beam, and the number of the connecting beams is two or more, arranged sequentially at intervals along the circumference of the support base;

[0011] Each of the connecting beams is provided with heat dissipation holes.

[0012] In some embodiments, the support base has ventilation holes along the centerline of the guide ring.

[0013] In some embodiments, a flange is provided at the first guide portion and / or the second guide portion;

[0014] And / or, the fan support is a one-piece molded structure.

[0015] This utility model also provides a fan structure, which includes a fan and a fan support as described above.

[0016] In some embodiments, the fan includes a hub and blades disposed on the outer peripheral sidewall of the hub; the motor of the fan is connected to the hub to drive the blades to rotate by driving the hub.

[0017] The blades are two or more in number and are arranged sequentially at intervals along the circumference of the hub; heat dissipation vents are provided on the outer peripheral sidewall of the hub between each pair of adjacent blades.

[0018] In some embodiments, an inner hole is formed on the inner side of the outer peripheral sidewall of the hub, and at least a portion of the motor extends into the inner hole.

[0019] In some embodiments, the motor is an external rotor motor, which has a rotor and a shaft fitted inside the rotor; the motor extends into the inner hole through the rotor and is fixedly connected to the hub through the shaft.

[0020] In some embodiments, when the motor bracket includes a support base and a connecting beam connected to the support base, and the motor bracket provides support for the motor through the support base, and the support base is connected to the guide ring through the connecting beam,

[0021] The motor has a lug on its outer side wall and a support portion on its support base; the support base is connected to the lug through the support portion so as to provide support for the motor through the lug and to create a gap t between the motor and the support base.

[0022] In some implementations, 5mm ≥ t ≥ 3mm.

[0023] In some embodiments, the fan is a reversible axial flow fan.

[0024] This utility model also provides an air conditioner, which includes the fan bracket as described above; or includes the fan structure as described above.

[0025] The fan bracket, fan structure, and air conditioner provided by this utility model have the following beneficial effects:

[0026] 1. Compared with the existing technology where the guide ring on the fan bracket can only guide the air generated by the fan rotating in the forward direction, this utility model provides a first guide part and a second guide part at both ends of the guide ring. The first guide part can guide the air generated when the fan is rotating in the forward direction, and the second guide part can guide the air generated when the fan is rotating in the reverse direction. In this way, the first guide part and the second guide part can guide the air on the fan bracket for both the forward and reverse rotation of the fan, thereby improving the practicality of the fan bracket of this utility model.

[0027] 2. By setting heat dissipation holes on the connecting beam that extend along the center line of the guide ring, it is beneficial to the airflow and heat dissipation of the fan.

[0028] 3. By designing heat dissipation vents on the hub, the weight of the fan blades can be reduced, thus decreasing their load power and lowering their cost. Furthermore, the vents accelerate airflow, improving heat dissipation from the motor housing. Additionally, the clearance between the hub and rotor can be reduced, allowing for a smaller hub diameter and thus a lower hub-to-displacement ratio, thereby increasing airflow.

[0029] 4. By setting a gap t between the motor and the support base, firstly, sufficient heat dissipation space is ensured at the bottom of the motor, improving the stability and reliability of the motor's heat dissipation; secondly, the motor will not directly contact the support base, thus preventing vibration transmission and noise.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0042] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0043] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0044] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0045] See also Figure 1-8 As shown, according to an embodiment of the present invention, a fan bracket 100 is provided, which includes a motor bracket 1 and a guide ring 2. The motor bracket 1 provides support for the motor 6 of the fan. The guide ring 2 is disposed on the motor bracket 1. The guide ring 2 is used to be sleeved on the outside of the fan blade 5. One end of the guide ring 2 has a first guide portion 21, which is used to guide the air generated when the fan rotates forward. The other end of the guide ring 2 has a second guide portion 22, which is used to guide the air generated when the fan rotates in reverse.

[0046] Compared to the existing technology where the guide ring on the fan bracket can only guide the air generated by the fan rotating in the forward direction, this utility model provides a first guide part 21 and a second guide part 22 at both ends of the guide ring 2. The first guide part 21 can guide the air generated when the fan is rotating in the forward direction, and the second guide part 22 can guide the air generated when the fan is rotating in the reverse direction. In this way, the first guide part 21 and the second guide part 22 can guide the air on the fan bracket 100 for both the forward and reverse directions of the fan, thereby improving the practicality of the fan bracket 100 of this utility model.

[0047] In order to achieve the functions of the aforementioned first guide section 21 and second guide section 22, in some embodiments, such as Figure 4 As shown, the end of the aforementioned first guide section 21 may have a first flare 210, through which the first guide section 21 guides the airflow generated when the fan rotates forward. Figure 1 As shown, the end of the aforementioned second guide section 22 may have a second flare 220, through which the second guide section 22 guides the air generated when the fan reverses.

[0048] In the above example, the first flare 210 on the first guide section 21 and the second flare 220 on the second guide section 22 cooperate to achieve the effect of guiding the airflow of the fan on the fan bracket 100 in both forward and reverse rotation.

[0049] It should be noted that one end of the aforementioned guide ring 2 can be turned outward to form the first guide portion 21, and the aforementioned first flare is formed on the inner side of the first guide portion 21. The other end of the guide ring 2 can be turned outward to form the second guide portion 22, and the aforementioned second flare 220 is formed on the inner side of the second guide portion 22. Since both ends of the guide ring 2 are turned outward, the guide ring 2 can sometimes also be referred to as the throat.

[0050] In some embodiments, the aforementioned guide ring 2 is integrally formed on the motor bracket 1, which can improve the connection stability between the guide ring 2 and the motor bracket 1.

[0051] In addition, compared with the existing technology that requires the fan bracket to be separately disassembled into multiple parts such as the motor bracket and the guide ring, this utility model integrally molds the guide ring 2 onto the motor bracket 1, resulting in fewer parts, lower cost, and improved assembly efficiency.

[0052] In some implementations, such as Figure 1-2As shown, the aforementioned motor bracket 1 may include a support base 11 and a connecting beam 12 connected to the support base 11. The motor bracket 1 provides support for the motor 6 through the support base 11. The support base 11 is connected to the guide ring 2 through the connecting beam 12. One end of the connecting beam 12 may be integrally formed on the support base 11, and the other end may be integrally formed on the guide ring 2. There are two or more connecting beams 12, which are arranged sequentially at intervals along the circumference of the support base 11. Each connecting beam 12 is provided with heat dissipation holes 120.

[0053] In the example above, the gap between each pair of adjacent connecting beams 12 forms an air passage, which helps the fan to exhaust air. In addition, by providing heat dissipation holes 120 on the connecting beams 12, the fan's heat dissipation is also improved.

[0054] It should be noted that the aforementioned connecting beam 12 may sometimes be referred to as a crossbeam, and there may be three crossbeams. The aforementioned support base 11 may sometimes be referred to as a central disc.

[0055] In some implementations, such as Figure 1-2 As shown, the aforementioned support base 11 may be provided with ventilation holes 110 along the center line of the guide ring 2 to improve the heat dissipation efficiency of the motor 6. The number of ventilation holes 110 may be two or more.

[0056] In some implementations, such as Figure 1-2 As shown, flanges 3 are provided at the aforementioned first guide section 21 and / or second guide section 22 to facilitate the installation and fixation of the fan bracket 100. When flange 3 is provided at the first guide section 21, it can be integrally formed onto the first guide section 21. Similarly, when flange 3 is provided at the second guide section 22, it can be integrally formed onto the second guide section 22.

[0057] In some embodiments, the aforementioned fan bracket 100 can be a one-piece molded structure, which combines the functions of the motor bracket 1 and the guide ring 2, resulting in a simple structure. This also reduces the number of parts in the fan bracket 100, lowers the cost, and improves the assembly efficiency with the fan.

[0058] In some embodiments, the present invention also provides a fan structure, which may include a fan and a fan bracket 100 as described above. Because the fan structure uses the aforementioned fan bracket 100, compared to the prior art where the guide ring on the fan bracket can only guide the airflow generated by the fan rotating in the forward direction, the present invention, through the provision of a first guide portion 21 and a second guide portion 22, allows the first guide portion 21 to guide the airflow generated when the fan is rotating in the forward direction, and the second guide portion 22 to guide the airflow generated when the fan is rotating in the reverse direction. Thus, the first guide portion 21 and the second guide portion 22 work together to guide the airflow on the fan bracket 100 for both forward and reverse rotation, thereby improving the practicality of the fan bracket 100 of the present invention.

[0059] In one specific application example, the aforementioned fan can be a reversible axial flow fan, allowing the fan structure to discharge air to either end of the axial direction or the other. The fan blades 5 of the reversible axial flow fan can be designed to have a relatively large air volume in both forward and reverse rotation. Combined with the first guide section 21 and the second guide section 22 of the guide ring 2, the air volume is optimized.

[0060] The fan structure of this utility model is based on the fact that the blades 5 of the above-mentioned reversible axial flow fan can rotate in both directions, so as to realize reversible upward and downward air outlet.

[0061] In some implementations, such as Figure 3-6 As shown, the aforementioned fan may include a hub 51 and blades 52 disposed on the outer peripheral sidewall 511 of the hub. The blades 52 may be integrally formed on the hub 51 to improve the connection stability between the blades 52 and the hub 51. The fan motor 6 is used to connect to the hub 51 to drive the hub 51 to rotate the blades 52. The number of blades 52 is two or more, and they are arranged alternately along the circumference of the hub 51. Heat dissipation vents 510 are provided on the outer peripheral sidewall 511 of the hub between each pair of adjacent blades 52.

[0062] In the above example, the hub 51 and the blade 52 cooperate to form the fan blade 5. The cooperation of each heat dissipation port 510 has the following advantages: on the one hand, it can reduce the weight of the fan blade 5, reduce the load power of the fan blade 5, and reduce its cost; on the other hand, the design of the heat dissipation port 510 accelerates the air flow, which speeds up the heat dissipation of the motor 6 housing.

[0063] In some implementations, such as Figure 3-6 As shown, an inner hole 520 is formed on the inner side of the outer peripheral sidewall 511 of the hub. At least a part of the motor 6 extends into the inner hole 520. In this way, the space of the inner hole 520 can be utilized to fully save the space in the axial direction of the fan, making the overall structure more compact.

[0064] In a specific application example, the aforementioned motor 6 can be an external rotor motor. The external rotor motor has a rotor 61 and a shaft 63 fixed inside the rotor 61. The motor 6 extends into the inner hole 520 via the rotor 61 and is fixedly connected to the hub 51 via the shaft 63. When the rotor 61 rotates, it drives the hub 51 to rotate together via the shaft 63. In the above example, there is a clearance between the rotor 61 and the inner hole 520. By providing a heat dissipation vent 510 on the outer peripheral sidewall 511 of the hub, the clearance between the hub 51 and the rotor 61 can be reduced, thereby reducing the diameter of the hub 51 and thus reducing the hub ratio (the ratio of the diameter of the hub 51 to the outer diameter of the fan blade 5, typically 0.2 to 0.3 in air conditioning), thereby increasing the airflow.

[0065] In some embodiments, the aforementioned rotor 61 may be shell-shaped, such that rotor 61 may sometimes be referred to as motor housing.

[0066] It should be noted that the aforementioned motor 6 can also be an internal rotor motor. That is, the motor 6 in this utility model can be either an external rotor motor or an internal rotor motor.

[0067] It should be noted that since the hub 51 encloses the aforementioned rotor 61, by providing heat dissipation vents 510 on the outer peripheral sidewall 511 of the hub, the outer peripheral sidewall 511 of the hub forms a partially incomplete wall surface. Although the diameter of the hub 51 remains unchanged, considering that the out-of-roundness of the outer peripheral sidewall 511 of the hub will be smaller, it is believed that the movement clearance between the hub 51 and the rotor 61 can be better guaranteed. Therefore, compared with the prior art, the diameter of the hub 51 can be reduced, allowing the hub 51 to be installed with a smaller diameter.

[0068] In some implementations, such as Figure 6 As shown, a through connection hole 521 is provided on the bottom surface of the aforementioned inner hole 520. The rotating shaft 63 of the aforementioned motor 6 passes through the connection hole 521 and is fixed to the hub 51 by a fastener such as a nut 7. The end of the outer peripheral sidewall 511 of the hub that opens into the inner hole 520 is designated as end A. The aforementioned heat dissipation vent 510 can pass through end A, so that the outer peripheral sidewall 511 of the hub forms a sawtooth structure at end A.

[0069] In some implementations, such as Figure 7-8 As shown, when the motor bracket 1 includes a support base 11 and a connecting beam 12 connected to the support base 11, and the motor bracket 1 provides support for the motor 6 through the support base 11, and the support base 11 is connected to the guide ring 2 through the connecting beam 12, the outer side wall of the aforementioned motor 6 is provided with a lug 9, and the support base 11 is provided with a support portion 4. The support base 11 is connected to the lug 9 through the support portion 4, so as to provide support for the motor 6 through the lug 9, and to make there a gap t between the motor 6 and the support base 11. Preferably, 5mm ≥ t ≥ 3mm.

[0070] In the above example, by setting a gap t between the motor 6 and the support base 11, firstly, it ensures that the bottom of the motor 6 has sufficient heat dissipation space, thereby improving the heat dissipation stability and reliability of the motor 6; secondly, since the motor 6 runs at high speed, it will generate vibration. The gap between the motor 6 and the support base 11 prevents the motor 6 from directly contacting the support base 11, thus preventing vibration transmission and noise.

[0071] In some embodiments, the aforementioned support 4 can be a screw post, and the screw post and the lug 9 can be fixedly connected by fasteners such as screws 8.

[0072] Among them, such as Figure 4 As shown, when the aforementioned motor 6 is an external rotor motor, and the external rotor motor has a rotor 61 and a rotating shaft 63 fitted inside the rotor 61, and the motor 6 extends into the inner hole 520 through the rotor 61 and is fixedly connected to the hub 51 through the rotating shaft 63, the external rotor motor has a fixed housing 62, and the aforementioned rotor 61 is rotatably mounted on the fixed housing 62. The aforementioned lug 9 can be fixedly mounted on the outer side wall of the fixed housing 62, for example, integrally formed on the outer side wall of the fixed housing 62.

[0073] In some embodiments, the present invention also provides an air conditioner that includes the fan bracket 100 of any of the above-mentioned components; or includes the fan structure of any of the above-mentioned components.

[0074] When the aforementioned fan structure is applied to an air conditioner, and the fan is a reversible axial flow fan, the air conditioner can achieve reversible vertical airflow. This aligns with the principle that hot air naturally rises and cold air naturally sinks, enabling whole-house air circulation while improving the operating efficiency of the air conditioning system and enhancing user comfort. Furthermore, because the reversible axial flow fan has a relatively simple structure, this design also solves the problem of traditional air conditioners requiring more complex and costly duct systems to achieve reversible vertical airflow.

[0075] In some embodiments, the aforementioned air conditioner can be an indoor unit. Furthermore, the aforementioned fan bracket 100 and fan structure are not only suitable for household air conditioners, but can also be widely applied in commercial and industrial air conditioning fields, possessing broad market prospects and application value.

[0076] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0077] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
