For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Please refer to Figure 1-4 The utility model provides an air outlet component, which can be applied to equipment with an air outlet, such as an air conditioner, a cooling fan, etc. Figure 1 As shown, the air outlet assembly is composed of an air outlet frame 1 and an air guide plate 2 connected thereto. The air outlet frame 1 is connected to the housing of the device, and mainly plays the role of supporting and fixing the air guide plate 2.

[0037] Specifically, if Figure 1-3 As shown, the air outlet frame 1 has an air outlet, and mounting holes 11 are opened on both sides of the air outlet. A rotating shaft 21 is provided on the air guide plate 2, and the rotating shaft 21 is rotatably provided on the mounting hole 11. By controlling the rotation angle of the air guide plate 2, the user can adjust the air outlet direction and air volume of the device.

[0038] Furthermore, the rotating shaft 21 and the air outlet frame 1 are connected in a contactless rotational manner through the magnetic field between the stator assembly 3 and the rotor assembly 4 .

[0039] Specifically, a rotor assembly 4 is provided on the rotating shaft 21, and a stator assembly 3 is embedded on the inner wall of the mounting hole 11, and the stator assembly 3 is connected to a power source. When an alternating current is passed through the stator assembly 3, the magnetic field in the stator coil will also change due to the change in the direction and magnitude of the current, thereby generating a rotating magnetic field. The rotating magnetic field acts on the rotor assembly 4 on the rotating shaft 21, so that the rotor assembly 4 is affected by the rotating magnetic field, generating a rotational torque, and the rotational torque can drive the rotating shaft 21 to drive the air guide plate 2 to rotate.

[0040] This solution utilizes the rotating magnetic field generated by the stator assembly 3 on the rotor assembly 4, and supports and controls the rotation of the rotating shaft 21 through the magnetic field force, thereby avoiding the mechanical connection between the air guide plate 2 and the air outlet frame 1, and avoiding the noise generated by the mechanical connection, thereby achieving contactless and high-precision rotational motion between the rotating shaft 21 and the air outlet frame 1.

[0041] This design not only improves the rotation efficiency, effectively reduces the friction and wear between mechanical parts, reduces the noise when the air guide plate 2 rotates in the air conditioning system, but also avoids possible failures due to jamming. The contactless rotation method of the air outlet assembly further improves the performance of the air conditioning product, meets the user's demand for comfortable and silent air conditioning equipment, and improves the user experience.

[0042] In one embodiment, a structure without mechanical connection is adopted between the rotating shaft 21 of the air guide plate 2 and the air outlet frame 1. When the stator assembly 3 is connected to the power supply, the air guide plate 2 can be suspended in the mounting hole 11 under the action of the rotating magnetic field force and rotate by the magnetic field force.

[0043] When the control system receives a power-off signal, a certain current is passed into the stator circuit as a holding current, so that even if a power failure occurs, the current in the stator assembly 3 will not drop to zero immediately, but will decay slowly. The holding current can maintain the magnetic field in the stator assembly 3, so that the rotor remains in a suspended state. As time goes by, the magnetic field in the stator assembly 3 gradually weakens, so that the rotating shaft 21 can slowly fall into the mounting hole 11.

[0044] Similarly, when the control system receives a power-on signal, the current in the stator assembly 3 does not increase immediately, but gradually increases, so that the rotating shaft 21 can gradually and smoothly rise to the working position, avoiding sudden impact force and pressure, making the equipment more stable and reliable during startup.

[0045] In one embodiment, a bearing (not shown in the figure) is arranged between the rotating shaft 21 and the mounting hole 11 of the air outlet frame 1, the outer ring of the bearing is connected to the mounting hole 11, and the inner ring of the bearing is connected to the rotating shaft 21.

[0046] A bearing is provided between the rotating shaft 21 and the mounting hole 11 to effectively support the rotational movement of the air guide plate 2, thereby ensuring its stability and reliability during operation.

[0047] In one embodiment, if Figure 2 and 3 As shown, the rotating shaft 21 includes a magnetic conductive end, and the rotor assembly 4 includes a plurality of permanent magnets 41 , which are arranged at intervals along the circumference of the magnetic conductive end.

[0048] Specifically, some shaft sections of the rotating shaft 21 are made of magnetic conductive materials, which have good magnetic conductivity and can effectively guide the magnetic field. In addition, other shaft sections of the rotating shaft 21 and the swing blades of the air guide plate 2 are made of lightweight non-magnetic conductive materials, which can reduce the weight of the entire system and improve the operating speed and response capability of the system.

[0049] The shaft section that uses magnetic conductive material is called the magnetic conductive end. The magnetic conductive end can effectively control and guide the magnetic field, avoid magnetic field loss and energy loss, and improve the transmission efficiency of magnetic force.

[0050] Preferably, the magnetic conductive ends are located at both ends of the rotating shaft 21 so that the air guide plate 2 is subjected to more uniform force and support when rotating.

[0051] Furthermore, a plurality of permanent magnets 41 are arranged at intervals along the circumferential direction of the magnetic conductive end. The magnetic conductive end on the rotating shaft 21 and the plurality of permanent magnets 41 together constitute the rotor assembly 4.

[0052] Specifically, the permanent magnet 41 can be fixed to the magnetic conductive end by adhesive bonding, or by clamps or nylon wires, etc. Such a fixing method can ensure that the connection between the permanent magnet 41 and the magnetic conductive end is stable and reliable, and is not easy to loosen or fall off.

[0053] The magnetic conductive end and the permanent magnet 41 form a structure of the rotor assembly 4, which can directly and effectively provide rotational power for the rotating shaft 21 to realize the rotation of the air guide plate 2. The structure is also simple and compact, which helps to reduce the assembly space of the rotor assembly 4 and reduce the manufacturing cost.

[0054] In one embodiment, each part of the air guide plate 2 is made of non-magnetic material. In this case, the rotor assembly 4 can adopt a structure in which a magnetic ring and a permanent magnet 41 are combined.

[0055] Specifically, a magnetic ring (not shown) is sleeved on the rotating shaft 21, and a plurality of permanent magnets 41 are arranged at intervals along the circumference of the magnetic ring on the outer surface of the magnetic ring. This combined structure enables the magnetic ring and the permanent magnets 41 to together form a rotor assembly 4, providing rotational power for the rotating shaft 21.

[0056] Furthermore, the combined structural form of the magnetic ring and the permanent magnet 41 not only simplifies the design and manufacturing process of the rotor assembly 4, but also facilitates the assembly and maintenance of the equipment, reducing the overall cost and complexity.

[0057] Furthermore, through this design, the air guide plate 2 can be made of a lighter, more cost-effective non-magnetic material, thereby reducing the weight and manufacturing cost of the device. By using lightweight materials to make the air guide plate 2, the inertial load of the system can be reduced, energy consumption can be reduced, and the operating efficiency and energy utilization rate of the system can be improved.

[0058] Preferably, magnetic steel can be selected as the material of the permanent magnet 41. Magnetic steel has excellent magnetic conductivity and stable magnetic properties, and can effectively generate and maintain a magnetic field, thereby achieving good magnetic force transmission and power output.

[0059] In one embodiment, the rotating shaft 21 includes a large diameter section 221 and a small diameter section 222 connected to each other, wherein the large diameter section 221 can be disposed in the mounting hole 11 as a magnetic conductive end to meet the requirements of the rotating magnetic field.

[0060] By dividing the rotating shaft 21 into a large-diameter section 221 and a small-diameter section 222 , the weight of the device can be reduced while ensuring the magnetic conductivity, thereby reducing power consumption and improving system performance.

[0061] In one embodiment, if Figure 4As shown, the stator assembly 3 includes a stator core 31 and a stator winding 32 (not shown in the figure). The stator core 31 is embedded in the mounting hole 11, and the stator core 31 is provided with a plurality of stator teeth 311 along the circumferential direction. The stator winding 32 is wound on the stator teeth 311.

[0062] Specifically, the stator core 31 is provided with a plurality of slot-shaped stator teeth 311 along the circumferential direction, and the stator winding 32 or the stator coil is wound on the stator teeth 311. The plurality of slot-shaped stator teeth 311 on the stator core 31 can make the stator winding 32 more evenly distributed on the stator core 31, thereby reducing electromagnetic noise and vibration.

[0063] Furthermore, the stator core 31 can be rolled from stator silicon steel sheets. Furthermore, in this embodiment, the stator core 31 can be arranged on the inner wall of the mounting hole 11 by hot pressing or interference fit plus vacuum glue injection, or the stator core 31 can be first hot pressed onto the metal shell, and then the associated shell is embedded into the inner wall of the mounting hole 11. This fixing method can improve the stability and sealing of the stator core 31.

[0064] It should be noted that the air outlet frame 1 needs to have certain mechanical strength and heat resistance at the position where the stator core 31 is installed to prevent the stator winding 32 from heating up and causing the air outlet frame 1 to deform or soften.

[0065] Furthermore, by passing currents of different directions into the stator winding 32 through the control system, the stator assembly 3 can generate rotating magnetic fields of different directions. In this way, the rotor assembly 4 can drive the air guide plate 2 to rotate in the rotating magnetic field. Furthermore, by adjusting the direction and intensity of the current, the rotation speed and direction of the air guide plate 2 can be controlled, thereby achieving the adjustment and distribution of the airflow in the device.

[0066] The present new embodiment also provides an indoor unit of an air conditioner, which adopts the air outlet assembly as described above.

[0067] Specifically, an air outlet is arranged on the shell of the indoor unit of the air conditioner, an air outlet component is installed at the air outlet, and the air outlet component is fixed on the shell through an air outlet frame 1.

[0068] Since the air guide plate 2 of the air outlet assembly and the air outlet frame 1 adopt a structure of matching connection of the stator assembly 3 and the rotor assembly 4, the structure effectively reduces the friction and vibration between the components and reduces the noise. At the same time, the use of this connection method can also avoid the phenomenon of jamming, ensuring the normal operation and stability of the air guide plate 2. Therefore, the indoor unit of the air conditioner using the air outlet assembly can provide a more comfortable and quiet environment, bringing a better user experience to the user.

[0069] In one embodiment, a plurality of air guide plates 2 are provided, and the plurality of air guide plates 2 are arranged at intervals along the first direction of the housing.

[0070] Specifically, the first direction is preferably the height direction of the air conditioner indoor unit when it is in normal use. For example, when the air conditioner indoor unit is a wall-mounted unit or a cabinet unit, multiple air guide plates 2 are arranged at intervals along the height direction of the shell. By providing multiple air guide plates 2, the air outlet direction can be effectively controlled and the air volume can be evenly distributed, thereby improving the air outlet effect of the air conditioner indoor unit.

[0071] Of course, the arrangement of the air guide plate 2 can be flexibly adjusted according to actual design requirements, which does not constitute a limitation to the present application.

[0072] The embodiment of the utility model also provides an air conditioner, including the air conditioner indoor unit as described above. Since the air conditioner indoor unit has the above characteristics and advantages, the air conditioner including the air conditioner indoor unit also has the same characteristics and advantages, and is more competitive in the market, which will not be described in detail herein.

[0073] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
