Description

Technical Field

[0001] This invention relates to the field of fan technology, and more specifically, to a fan assembly and an air conditioner. Background Technology

[0002] A typical air conditioner (indoor unit) includes at least two air vents: one for air outlet and the other for air return. Airflow is directed between these vents by a fan within the indoor unit. As people's demands for air conditioning comfort increase, the indoor unit needs to switch airflow direction according to the operating mode. However, because the fan blades have directional requirements, reversing the motor that drives them makes airflow reversal difficult, resulting in a fixed airflow direction that cannot be adjusted and fails to meet diverse user needs. Some solutions utilize multiple mixed-flow fans that rotate 180° within the indoor unit, achieving reverse airflow.

[0003] Drive systems used to rotate fans often employ motors and rotating mechanisms to drive the fan. A key challenge is ensuring that the motor is powered while the motor wires remain untwisted. Traditional methods address this through two points: either selecting anti-torsion wire materials or lengthening the wire's rotation path to distribute stress and prevent concentrated damage. However, these traditional methods only extend the wire's lifespan and do not completely solve the problem of wire damage caused by twisting.

[0004] In summary, the existing technology addresses the problem of wire damage caused by twisted wires in the motor wires of rotatable fans. Summary of the Invention

[0005] This invention provides a fan assembly and an air conditioner to solve the problem of wire damage caused by twisted wires in the motor wires of a rotatable fan.

[0006] To achieve the above objectives, the present invention provides a fan assembly, including a fan, a motor wire, and a rotating mechanism. The fan includes a volute and a motor disposed inside the volute. The rotating mechanism is driven to the volute and drives the fan to rotate. The motor is electrically connected to the outside via the motor wire. The motor wire includes: a first segment, which is directly connected to the motor and is disposed on the volute and moves synchronously with the volute; and a second segment, which is electrically connected to the outside. The first segment is electrically connected to the second segment via a rotating node located inside the rotating mechanism.

[0007] Furthermore, the rotating mechanism includes a housing with an installation space for placing the driving components, and the rotating node is located within the installation space.

[0008] Furthermore, it also includes: a mounting base, which is mounted on the outer casing, with its first end connected to the volute and its second end located within the mounting space; a rotating node is located at the second end of the mounting base, and a first line segment passes through the first end of the mounting base and is electrically connected to the rotating node.

[0009] Furthermore, the mounting base is connected to the volute, and the rotating node is set on the mounting base. The rotating node, the mounting base, and the volute rotate synchronously.

[0010] Furthermore, at least part of the second line segment is located within the installation space, and the portion of the second line segment located within the installation space has a reserved length for the rotating node to rotate and drive the line body.

[0011] Furthermore, the driving component includes: a drive motor, disposed within the installation space; and a transmission mechanism, which is driven and connected to the drive motor and the volute, wherein the drive motor drives the volute to rotate through the transmission mechanism.

[0012] Furthermore, at least part of the second line segment is located within the installation space, and the portion of the second line segment located within the installation space has a reserved length for the rotating node to rotate and drive the line body; the wiring of the portion of the second line segment located within the installation space is staggered from the transmission mechanism, and the wiring of the portion of the second line segment located within the installation space is wound around the drive motor.

[0013] Furthermore, the rotating node is an onboard connector.

[0014] Furthermore, there are multiple fans, all connected in sequence, all fans can rotate simultaneously and change the direction of the air outlet, and the rotation axes of all fans are collinear.

[0015] Furthermore, there are multiple first line segments, and the number of first line segments is set to correspond one-to-one with the number of motors. All first line segments are aggregated at the rotation node.

[0016] Furthermore, the second line segment is a single line, and all the first line segments are electrically connected to the second line segment through rotating nodes.

[0017] Furthermore, there are multiple second line segments, and each second line segment is connected to the first line segment in a one-to-one correspondence.

[0018] Furthermore, at least one fan is driven by a rotating mechanism, which is connected to the fan drive to drive all the fans to rotate.

[0019] Furthermore, the fan located at the head end of all fans is driven and connected to the rotating mechanism; along the direction from the tail end to the head end of all fans, the first line segment corresponding to the fan passes through the wiring of other fans in sequence to the rotating node.

[0020] Furthermore, the fan is equipped with a cable tray, and the first cable segment is routed within the cable tray.

[0021] Furthermore, the motor seal is located inside the mounting housing, the motor wire passes through the mounting housing, and a sealing ring is provided on the motor wire. The motor wire is sealed to the mounting housing through the sealing ring.

[0022] Furthermore, the motor wire body and the sealing ring are integrally formed.

[0023] According to another aspect of the present invention, an air conditioner is provided, comprising the fan assembly described above.

[0024] Furthermore, the air conditioner is a ducted unit.

[0025] Furthermore, the fan is any one of a mixed-flow fan, an axial-flow fan, or a centrifugal fan.

[0026] The motor wires are designed in multiple sections. The first section is fixed to the volute and rotates synchronously with it. The motor wires inside the volute are guaranteed not to twist. The rotation node between the second and first sections is placed within the rotating mechanism, thus resolving the problem of twisting and tangling of the motor wires inside the volute. Simultaneously, the rotation of the fan inevitably rotates the motor wires. This rotational load is absorbed by the second section, with the rotation node located within the rotating mechanism. The second section can absorb the rotational load as needed, placing it within the rotating mechanism. This design, through the arrangement and coordination of multiple sections of the motor wires, prevents twisting during fan rotation, completely eliminating wire loss caused by twisting. Furthermore, absorbing the rotational load within the rotating mechanism results in a compact structure. Even if disassembly and maintenance of the motor wires are required, since the first section is unlikely to be damaged by twisting, only the rotating mechanism needs to be disassembled, making maintenance convenient.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0034] See Figures 1 to 6 As shown, according to an embodiment of the present invention, a fan assembly is provided. The fan assembly includes a fan 10, a motor wire 20, and a rotating mechanism 30. The fan 10 includes a volute 11 and a motor 12 disposed inside the volute 11. The rotating mechanism 30 is drivenly connected to the volute 11 and drives the fan 10 to rotate. The motor 12 is electrically connected to the outside via the motor wire 20. The motor wire 20 includes a first segment 21 and a second segment 22. The first segment 21 is directly connected to the motor 12 and is disposed on the volute 11 and moves synchronously with the volute 11. The second segment 22 is electrically connected to the outside. The first segment 21 is electrically connected to the second segment 22 via a rotating node 23, which is located inside the rotating mechanism 30.

[0035] The motor wire 20 is designed in multiple parts. The first segment 21 is fixed to the volute 11 and rotates synchronously with it. The motor wire 20 located inside the volute 11 will not twist. Simultaneously, the rotation node 23 between the second segment 22 and the first segment 21 is placed within the rotation mechanism 30. This means the node where rotation occurs is moved to the rotation mechanism 30, thus solving the problem of twisting and tangling of the motor wire 20 inside the volute 11. Furthermore, the rotation of the fan 10 inevitably rotates the motor wire 20. This rotational amount is borne by the second segment 22, and the rotation node 23 is located within the rotation mechanism. The second segment can absorb the rotational amount as needed, placing it within the rotation mechanism. By designing the multiple parts of the motor wire 20 and their coordinated relationships, the motor wire 20 of the fan 10 will not twist when the fan 10 rotates, completely eliminating the problem of wire loss caused by twisting. Furthermore, the rotation of the motor wires is absorbed by the rotating mechanism, making the structure very compact. Even if the motor wires need to be disassembled for maintenance, the first segment of the wires will not be twisted or damaged, so only the rotating mechanism needs to be disassembled, making maintenance convenient.

[0036] Preferably, the rotating mechanism 30 includes a housing 31, within which is an installation space 32 for housing the driving component, and the rotating node 23 is located within the installation space 32. The rotating node 23 is positioned within the installation space 32 inside the housing 31, ensuring that the point of rotation is contained within the installation space 32. The rotation of the motor wires caused by this rotation is completed within the installation space 32, preventing interference with the coordination of the rotating mechanism with other structures and avoiding wiring interference and wear problems at the second segment of the motor wires. Furthermore, the installation space 32 serves both as a space for housing the driving component and as a rotation space for the rotating node 23, achieving a multi-functional purpose.

[0037] See Figure 4 The fan assembly also includes a mounting base 40, which is mounted on the outer casing 31. The first end of the mounting base 40 is connected to the volute 11, and the second end of the mounting base 40 is located within the mounting space 32. A rotating node 23 is located at the second end of the mounting base 40, and a first line segment 21 passes through the first end of the mounting base 40 and is electrically connected to the rotating node 23.

[0038] The first line segment can be passed through a through hole between the first and second ends of the mounting base 40, or a wiring groove can be arranged to place the first line segment. The specific structure can be selected according to the needs, and its arrangement will not be described in detail. The function of the mounting base is to provide a structural transition. Placing the rotating node 23 on the mounting base can increase its stability and ensure that it is not restricted by the structure of the rotating mechanism.

[0039] Preferably, the mounting base 40 is connected to the volute 11, and the rotating node 23 is disposed on the mounting base 40. The rotating node 23, the mounting base 40, and the volute 11 rotate synchronously. In this embodiment, the mounting base 40 is fixedly connected to the volute 11. The structure of the mounting base 40 itself can serve as a link in the transmission system driven by the rotating mechanism. That is, the drive motor 51 of the rotating mechanism drives the mounting base through the transmission mechanism 52, and the mounting base drives the volute to rotate. The mounting base can serve as a transmission component. Of course, in other embodiments not shown in the figures, the mounting base 40 can also serve as a transitional structure, used only for mounting the rotating node and rotating synchronously with the volute. In other words, there is no limitation on the specific structural form of the mounting base. For example, using a component of the rotating mechanism as the mounting base can also achieve the same structural configuration.

[0040] Combination Figure 3 and Figure 6As shown, at least part of the second line segment 22 is located within the installation space 32. The portion of the second line segment 22 within the installation space 32 has a reserved length for the rotating node 23 to rotate and drive the cable. The rotation of the fan inevitably rotates the motor cable, and this rotational amount is borne by the second line segment. The second line segment has sufficient reserved length for its own rotation and will not twist. Placing the portion of the second line segment 22 that absorbs the rotational amount within the installation space does not affect the external wiring of the rotating mechanism, nor does it cause structural interference problems due to cable rotation. This also minimizes cable wear on the second line segment.

[0041] In the fan assembly of this embodiment, the driving component includes a drive motor 51 and a transmission mechanism 52. The drive motor 51 is disposed within the mounting space 32. The transmission mechanism 52 is drivenly connected to the drive motor 51 and to the volute 11. The drive motor 51 drives the volute 11 to rotate via the transmission mechanism 52. In this embodiment, the transmission mechanism 52 is a set of transmission gears, see [reference needed]. Figure 4 The structure and positional relationship are as follows: one of the transmission gears is mounted on the mounting base 40, and the mounting base 40 rotates synchronously with the transmission gear. The output shaft of the drive motor 51 drives the transmission gear to rotate, which in turn drives the mounting base 40 to rotate. The mounting base 40 and the volute are drivenly connected and rotate synchronously, thus further driving the volute to rotate. The structure of the transmission mechanism 52 can be selected according to specific needs, such as a linkage mechanism, worm gear, belt, etc. This invention does not impose specific limitations, but any mechanism that can achieve the transmission function falls within the protection scope of this invention.

[0042] Combination Figure 3 and Figure 4 As shown, to further optimize the routing of the second line segment, in this embodiment, preferably, the second line segment 22 is at least partially located within the mounting space 32. The portion of the second line segment 22 within the mounting space 32 has a reserved length for the rotating node 23 to rotate and drive the line body. The routing of the portion of the second line segment 22 within the mounting space 32 is staggered from the transmission mechanism 52, and this portion of the routing is wound around the drive motor 51. First, the portion of the second line segment 22 within the mounting space 32 will not affect the operation of the transmission mechanism, thus preventing wear on the second line segment by the transmission mechanism. It also prevents the second line segment from becoming entangled in the transmission mechanism, preventing mutual interference. Second, considering the heat generated by the drive motor and the need for its maintenance, winding the portion of the second line segment 22 within the mounting space 32 around the drive motor 51 effectively prevents the second line segment from being heated and softened. Furthermore, the layout of the second line segment does not affect the operation of the drive motor during maintenance, facilitating maintenance.

[0043] Specifically, the rotation node 23 is the point where the first line segment 21 and the second line segment 22 meet. As the intersection of the two rotational trajectories of the motor line 20, the first line segment 21 rotates synchronously with the volute 11. After the rotation node 23, the rotation of the second line segment 22 is determined by the structure and trajectory of the rotation node 23. The function of the second line segment 22 is to absorb the rotation of the motor line 20, while the rotation node 23 separates the rotation of the first line segment 21 and the second line segment 22. The rotation node 23 can be a fixed structure at the junction of two line segments in the motor line 20, such as a fixing clamp or a fixing latch.

[0044] In this embodiment, the rotating node 23 is an onboard connector, the structure of which is described in [reference needed]. Figure 4 In other words, in this embodiment, the first segment 21 and the second segment 22 are electrically connected via an onboard connector. The onboard connector is a socket with a line jack, generally used for circuit connections; its structure is existing technology and will not be described further here. The advantage of using an onboard connector in this embodiment is that it can both complete the electrical connection between the first segment 21 and the second segment 22 and separate the rotation trajectories of the first segment 21 and the second segment 22, serving a dual purpose. The onboard connector is located within the mounting space 32, but it rotates with the volute 11. The synchronous rotation of the first segment 21 with the volute 11 remains unchanged, while the second segment 22 connected to the onboard connector absorbs the rotation of the onboard connector, which is also the rotation of the motor wire 20.

[0045] See Figure 1 The system comprises multiple fans 10 connected sequentially. All fans 10 can rotate simultaneously and change the direction of their air outlets. The rotation axes of all fans 10 are collinear. By aligning the rotation axes of all fans 10, no clearance is required between them. The spacing between fans 10 can be reduced or eliminated, significantly reducing the space occupied by the fan components, shortening the overall length of the air conditioner, and enhancing product competitiveness.

[0046] The number of first line segments 21 is adjusted according to the number of fans 10. There are multiple first line segments 21, and the number of first line segments 21 corresponds one-to-one with the number of motors 12. All first line segments 21 are connected to the rotation node 23. Each fan 10 is configured with a separate first line segment 21.

[0047] In this embodiment, there are multiple second line segments 22, each corresponding to a first line segment 21. To facilitate speed control of different fans 10, each motor line 20 is managed separately, controlling its electrical signal to control the rotation of each fan 10. In another embodiment (not shown), the second line segment 22 is a single line, and all first line segments 21 are electrically connected to the second line segment 22 via a rotation node 23. The power supply component 80 directly connects to and supplies power to multiple fans 10 via a single second line segment 22.

[0048] Preferably, at least one fan 10 is connected to a rotating mechanism 30, and the rotating mechanism 30 is driven by the fan 10 to drive all the fans 10 to rotate. There can be two or three rotating mechanisms. With two rotating mechanisms, one rotating mechanism can drive one or more fans 10, and the other rotating mechanism can drive the remaining fans 10, thereby reducing the load on each rotating mechanism. At the same time, when one rotating mechanism fails, it can still be driven by another rotating mechanism, thereby ensuring the reliability of the duct machine operation.

[0049] Combination Figure 1 and Figure 6 As shown, the fan 10 located at the head end of all fans 10 is connected to the drive unit, and the rotation node 23 is located at the drive unit. Along the direction from the tail end to the head end of all fans 10, the first line segment 21 corresponding to fan 10 sequentially passes through the other fans 10 to the rotation node 23. The fans 10 are arranged such that the rotation axes of all fans 10 are collinear, see [reference needed]. Figure 1 The arrangement, Figure 1 In the direction from left to right, located in Figure 1 The leftmost one is wind turbine 10, located at the beginning of all wind turbines 10. Figure 1 The rightmost one is the fan 10 located at the end of all the fans 10. The direction of the motor wire 20 is from... Figure 1 From right to left, the motor wire 20 passes through the middle fan 10 and the leftmost fan 10 in sequence, and then converges at the rotation node 23 at the position of the drive device.

[0050] Preferably, the fan 10 is provided with a wiring groove 10a inside, and the first wire segment 21 is routed in the wiring groove 10a. The wiring groove 10a is set on the inner wall of the volute 11. This does not affect the energy efficiency of the fan 10 and can also make the first wire segment 21 of the motor wire 20 rotate synchronously.

[0051] The entire fan 10 is located inside a condensation-prone air duct. The motor 12 inside the fan 10 experiences condensation due to the exchange of hot and cold air within the duct cavity. The condensation point is located at the interface of the motor wire 20, which enters the motor 12, resulting in a small amount of air inside the motor 12. This condensation problem occurs when switching between heating and cooling modes. Over time, this corrosion will damage the enameled wires and mainboard components inside the motor 12, ultimately harming the motor 12. To solve this problem, in this embodiment, the motor 12 is sealed within the mounting housing 60. The motor wire 20 passes through the mounting housing 60, and a sealing ring 70 is provided on the wire body of the motor wire 20. The motor wire 20 is sealed to the mounting housing 60 through the sealing ring 70. (See [reference]). Figure 5 The mounting housing 60 is constructed by integrating the front cover 61 and the rear cover 62, placing the motor 12 inside the mounting housing 60. A sealing ring 70 is used to achieve a seal, preventing moisture from entering the mounting housing 60 and thus solving the condensation problem on the motor 12.

[0052] To facilitate production and disassembly, the motor wire 20 and the sealing ring 70 are integrally molded. Disassembly and assembly only require direct manipulation of the motor wire 20; no special manipulation of the sealing ring 70 is necessary. Since both the wire and the sealing ring 70 can be made of insulating rubber, the production difficulty is very low, and it is easier to reduce costs compared to manufacturing them separately.

[0053] This invention also provides an embodiment of an air conditioner, including the fan assembly of the above embodiment, wherein the air conditioner is a ducted air conditioner. The fan is any one of a mixed-flow fan, an axial fan, or a centrifugal fan. In this embodiment, the fan is a mixed-flow fan. A mixed-flow fan is a mixed-flow fan that is between an axial mixed-flow fan and a centrifugal mixed-flow fan. The impeller of the mixed-flow fan causes the air to undergo both centrifugal and axial motion, and the airflow motion inside the volute combines both axial and centrifugal motion forms, hence the name "mixed-flow". Because mixed-flow fans can not only be made smaller in size, but also ensure the airflow direction and air pressure, the mixed-flow fan is installed in the ducted air conditioner to achieve reversible airflow and change the air outlet direction. In some other embodiments not shown in the figures, the fan can also be an axial fan or a centrifugal fan.

[0054] The ducted air conditioner has a downdraft and a side vent on its casing, and the fan has a first orientation and a second orientation. When the ducted air conditioner is in cooling mode, the fan is in the first orientation, with air entering through the downdraft and exiting through the side vent. When the ducted air conditioner is in heating mode, the fan is in the second orientation, with air entering through the side vent and exiting through the downdraft.

[0055] Furthermore, the ducted air conditioning unit also includes mounting brackets, on which all fans are connected. Specifically, multiple fans are strung together like a skewer of candied hawthorns, with adjacent fans fixed to each other. Therefore, to simplify the overall assembly structure, mounting brackets can be placed on the fans at both ends. During assembly, the fans and mounting brackets form a single unit, with the fans secured within the ductwork by the mounting brackets. During installation, the fans are first installed onto the mounting brackets, and then the mounting brackets are secured within the ductwork. For disassembly, the mounting brackets are removed, and the fans can be taken out along with them. Compared to traditional ducted air conditioning units with rotatable fans, the disassembly and assembly process is much simpler for operators. Moreover, removing the fans and mounting brackets as a whole allows for disassembly and maintenance in a spacious and well-lit area, making the operation more convenient and improving work efficiency.
