Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a wall-mounted air conditioning indoor unit. Background Technology

[0002] With the development of science and technology, the number of air conditioners is constantly increasing, and their functions are becoming more and more diverse. In particular, as people's living standards continue to improve, users have a great demand for the diversified functions of air conditioners. For example, the wide-range airflow function of air conditioners, and the left and right swing airflow for rapid cooling or heating modes, all require the air conditioner's oscillating blades to work together to achieve these functions.

[0003] Currently, in existing technologies, some air conditioning outlet devices are equipped with multiple swivel blades, with the blades inclined along the length of the air outlet to provide a novel air conditioning outlet method. Each swivel blade is connected sequentially via its own laterally arranged rotating shaft. However, one end of the rotating shaft has an axially extending plug-in shaft, and the other end is a hollow structure. Multiple shafts are connected together by sequentially plugging in the plug-in shaft and the hollow structure. The rotating shaft of each swivel blade not only drives the blade to rotate, but the connected rotating shafts also have to bear the weight of all the swivel blades. If the number of swivel blades is increased to ensure the airflow guiding effect, the structure of sequentially plugging in the plug-in shaft and hollow structure simply cannot bear the weight of all the swivel blades. Even a slight increase in the operating intensity of the swivel blades can cause them to detach from the air outlet assembly. The stability of the swivel blades installed at the air outlet cannot be guaranteed, let alone their normal operation. Utility Model Content

[0024] Furthermore, multiple blades are sequentially connected via a rotating cylinder shaft; and,

[0025] The blade is located at the middle of the rotating cylinder shaft in its axial direction.

[0032] Furthermore, both the rotating cylinder shaft and the support shaft are made of plastic, with the outer diameter of the support shaft being greater than or equal to 3mm and the inner diameter of the rotating cylinder shaft being greater than or equal to 5mm; or,

[0040] This utility model discloses a wall-mounted air conditioner indoor unit. Because a supporting shaft is inserted inside the rotating cylinder shaft of multiple swing blades, and both ends of the supporting shaft are connected to the two ends of the air outlet duct, the supporting shaft, stably connected to both ends of the air outlet duct, bears the weight of all the swing blades. This effectively alleviates or even prevents the swing blades from detaching from the air outlet when the number of swing blades or the operating intensity of the swing blades is increased. Therefore, this utility model's wall-mounted air conditioner indoor unit can improve the stability of the swing blades assembled at the air outlet, ensuring the normal operation of the swing blades.

When a feature "includes or contains" one or more of the features it encompasses, unless otherwise specifically stated, this indicates that other features are not excluded and may be further included.

[0057] Unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

That is, in the description of this embodiment, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," or "below" of the second feature can mean the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0059] Unless otherwise specified, all terms (including technical and scientific terms) used in the description of these embodiments have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0060] In the description of this embodiment, the use of terms such as "this embodiment" refers to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0061] The following is combined Figures 1 to 12 The wall-mounted air conditioner indoor unit of this embodiment will be described in detail below. Wherein, Figure 1 The image shows the state of multiple louvers on the indoor unit of a wall-mounted air conditioner when it is in natural wind mode. Figure 2 The image shows the state of multiple louvers when the indoor unit of the wall-mounted air conditioner is in directional air supply mode.

[0062] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the wall-mounted air conditioner indoor unit may include a housing 100, multiple swivel blades 200, and a support shaft core 300.

[0063] An air outlet 110 is provided on the front side of the housing 100, and an air outlet duct 120 communicating with the air outlet 110 is provided inside the housing 100.

[0064] Multiple oscillating blades 200 are distributed laterally within the air outlet duct 120, and multiple oscillating blades 200 are arranged adjacent to the air outlet 110. Multiple oscillating blades 200 are used to guide the flow direction of the air outlet in the lateral direction. Each oscillating blade 200 includes a rotating cylinder shaft 210 arranged laterally and blades 220 inclinedly arranged on the rotating cylinder shaft 210.

[0065] The support shaft core 300 is arranged in the horizontal direction and passes through the rotating cylinder shaft 210 of multiple swing blades 200. The two ends of the support shaft core 300 are respectively connected to the two ends of the air outlet duct 120 in the horizontal direction.

[0066] Because the wall-mounted air conditioner indoor unit of this embodiment has a support shaft core 300 passing through the rotating cylinder shaft 210 of multiple swing blades 200, and the two ends of the support shaft core 300 are connected to the two ends of the air outlet duct 120, the support shaft core 300, which is stably connected to the two ends of the air outlet duct 120, bears the weight of all the swing blades 200. This effectively alleviates or even avoids the situation where the swing blades 200 detach from the air outlet 110 if the number of swing blades 200 is increased or the operating intensity of the swing blades 200 is increased. Therefore, the wall-mounted air conditioner indoor unit of this embodiment can improve the stability of the assembly of each swing blade 200 at the air outlet 110, ensuring the normal operation of the swing blades 200.

[0067] In addition, in this embodiment, horizontal refers to the left and right direction.

[0068] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the wall-mounted air conditioner indoor unit also includes a base 400.

[0069] The base 400 includes a first air duct plate 410 and a second air duct plate 420 disposed opposite to each other. The first air duct plate 410 and the second air duct plate 420 are used to define the two side walls of the air duct 120 in the horizontal direction. The two ends of the support shaft core 300 are respectively connected to the first air duct plate 410 and the second air duct plate 420.

[0070] It is important to understand that the entire load-bearing component of the indoor unit of the air conditioner is the base 400, and the base 400 is directly mounted on the wall. This allows the two ends of the support shaft core 300 to be directly connected to the first air duct plate 410 and the second air duct plate 420 of the base 400, thereby further improving the stability of the swing blades 200 at the air outlet 110 and ensuring the normal operation of the swing blades 200.

[0071] Reference Figure 2 , Figure 5, Figure 6 and Figure 7 In this embodiment, multiple swing blades 200 are sequentially connected by a rotating cylinder shaft 210; and the wall-mounted air conditioner indoor unit may also include a drive component 500.

[0072] The driving component 500 is disposed on the first air duct plate 410, and the driving component 500 drives the rotating cylinder shaft 210 connected to the swing blades 200 disposed on the adjacent first air duct plate 410. The driving component 500 is used to drive each swing blade 200 to rotate through the rotating cylinder shaft 210 connected in sequence.

[0073] It should be understood that since the blades 200 are connected in sequence by rotating cylinder shafts 210, the drive unit 500 can drive only the rotating cylinder shafts 210 of the blades 200 connected to the adjacent first air duct plate 410. Thus, when the rotating cylinder shafts 210 of the adjacent first air duct plate 410 rotate, it can drive the other rotating cylinder shafts 210 to rotate, and thus each blade 200 can rotate.

[0074] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment, the driving component 500 may include a driving motor 510, a driving connector 520, and a driving bushing 530.

[0075] The drive motor 510 is mounted on the first air duct plate 410 and is located on the side of the first air duct plate 410 facing away from the air outlet duct 120.

[0076] The drive connector 520 extends laterally, and one end of the drive connector 520 is connected to the motor shaft of the drive motor 510.

[0077] The drive bushing 530 extends laterally and is sleeved on the support shaft core 300. One end of the drive bushing 530 is driven to the rotating cylinder shaft 210 of the swing blade 200 provided on the adjacent first air duct plate 410. The other end of the drive connector 520 passes through the first air duct plate 410 and is driven to the other end of the drive bushing 530.

[0078] It is understandable that placing the drive motor 510 on the side of the first air duct plate 410 facing away from the air outlet duct 120 can prevent the drive motor 510 from affecting the air pressure of the air outlet, ensuring the airflow rate and guaranteeing the user experience.

[0079] The motor shaft is driven to connect to the drive connector 520 via a flat part on it. The drive connector 520 is connected to the drive shaft sleeve 530 through it, and the drive connector 520 is also driven to connect to the drive shaft sleeve 530 via a flat part on it.

[0080] Furthermore, when installing the support shaft core 300 and the drive component 500, the drive shaft sleeve 530 can first be fitted onto the support shaft core 300 and connected to the rotating cylinder shaft 210 (of the oscillating blade 200) provided on the adjacent first air duct plate 410. Then, the drive connector 520 is passed through the first air duct plate 410 and connected to the drive shaft sleeve 530. Finally, the motor shaft is connected to the drive shaft sleeve 530, and the drive motor 510 is connected to the side of the first air duct plate 410 facing away from the air outlet duct 120. Therefore, the drive component 500 is configured separately as the drive motor 510, the drive connector 520, and the drive shaft sleeve 530 to facilitate the assembly of the support shaft core 300 and the oscillating blade 200 on the air conditioner indoor unit, thereby improving the assembly efficiency of the air conditioner indoor unit.

[0081] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment, the two ends of the drive shaft sleeve 530 and the rotating cylinder shaft 210 are respectively provided with a plurality of drive grooves 540 and a plurality of drive protrusions 550. The plurality of drive grooves 540 are arranged at intervals in the circumferential direction at their respective ends, and the plurality of drive protrusions 550 are arranged at intervals in the circumferential direction at their respective ends. Each drive protrusion 550 is inserted into the corresponding drive groove 540.

[0082] It is understandable that by setting the drive groove 540 and the drive protrusion 550, the drive shaft sleeve 530 can be driven to connect with the rotating cylinder shaft 210 of the swing blade 200 set in the adjacent first air duct plate 410.

[0083] Reference Figure 8 , Figure 9 and Figure 10 In this embodiment, a support fixing seat 421 is provided on the second air duct plate 420 at the position corresponding to the support shaft core 300, and a fixing groove 4211 is provided on the support fixing seat 421 to open toward the support shaft core 300; and a fixing sleeve 310 is sleeved on the end of the support shaft core 300 facing the second air duct plate 420, and a plurality of fixing blocks 311 are arranged in the circumferential direction of the fixing sleeve 310, and the fixing blocks 311 and the fixing sleeve 310 are embedded in the fixing groove 4211.

[0084] Understandably, the arrangement of the support mounting base 421, the mounting groove 4211, the mounting sleeve 310, and the mounting block 311 allows the support shaft core 300 to be quickly and stably fixed on the second air duct plate 420, thereby further improving the stability of the assembly of each blade 200 at the air outlet 110, ensuring the normal operation of the blades 200, and further ensuring the assembly efficiency of the support shaft core 300 and the blades 200 on the air conditioning indoor unit.

[0085] In addition, when assembling the support shaft core 300, one end of the support shaft core 300 can be first assembled onto the second air duct plate 420, and then the other end of the support shaft core 300, after assembling the drive shaft sleeve 530, can be assembled onto the drive connector 520 on the first air duct plate 410. Specifically, assembling one end of the support shaft core 300 onto the second air duct plate 420 can be done by first fitting the fixing sleeve 310 and fixing block 311 together onto the support shaft core 300, and then inserting the support shaft core, fixing sleeve 310, and fixing block 311 together into the fixing groove 4211.

[0086] Reference Figure 8 , Figure 9 and Figure 10 In this embodiment, the wall-mounted air conditioner indoor unit may also include a limiting spring 600.

[0087] The limiting spring 600 is sleeved on the support shaft core 300, and the limiting spring 600 is located between the fixed sleeve 310 and the rotating cylinder shaft 210 of the adjacent second air duct plate 420. The limiting spring 600 is used to cause the two adjacent swing blades 200 to abut against each other.

[0088] Understandably, the setting of the limit spring 600 can ensure that two adjacent swing blades 200 can abut against each other, thereby alleviating or even preventing the swing blades 200 from shaking on the support shaft core 300, ensuring the stability of the operation or air delivery of each swing blade 200, ensuring the user experience, and at the same time alleviating or even preventing the wear or damage of the swing blades 200 caused by shaking, thus extending the service life of the swing blades 200.

[0089] Furthermore, when the limit spring 600 is installed, when installing the support shaft core 300 and the drive component 500, the drive connector 520 can be first passed through the first air duct plate 410. Then, the motor shaft is connected to the drive shaft sleeve 530 and the drive motor 510 is connected to the side of the first air duct plate 410 facing away from the air outlet duct 120. Finally, after the drive shaft sleeve 530 is fitted onto the support shaft core 300, the drive shaft sleeve 530 is pushed relative to the support shaft core 300 toward the end of the support shaft core 300 connected to the second air duct plate 420. This compresses the limiting spring 600 through each rotating cylinder shaft 210, causing the drive shaft sleeve 530 and the entire drive shaft sleeve 530 to move toward the end of the support shaft core 300 connected to the second air duct plate 420. This creates a certain space at the end of the support shaft core 300 where the drive shaft sleeve 530 is fitted. Then, the drive shaft sleeve 530 and the drive connector 520 are aligned and the drive shaft sleeve 530 is released, thus completing the installation of the support shaft core 300 and the drive component 500.

[0090] Therefore, the setting of the limit spring 600 further facilitates the assembly of the support shaft core 300 and the swing blade 200 on the air conditioner indoor unit, and further improves the assembly efficiency of the air conditioner indoor unit.

[0091] Reference Figure 8 , Figure 9 and Figure 10 In this embodiment, the wall-mounted air conditioner indoor unit may also include a spring pressure plate 610. The spring pressure plate 610 is sleeved on the support shaft core 300, and the spring pressure plate 610 is disposed between the limiting spring 600 and the rotating cylinder shaft 210 disposed adjacent to the second air duct plate 420.

[0092] It is understandable that by setting the spring pressure plate 610, the stability of the rotating cylinder shaft 210 set in the adjacent second air duct plate 420 during the compression and release of the limit spring 600 can be guaranteed.

[0093] Reference Figure 3 and Figure 11 In this embodiment, the blade 220 is located at the middle of the rotating cylinder shaft in its axial direction. The two connecting ends of the two connected rotating cylinder shafts 210 are respectively provided with a plurality of cylinder grooves 211 and a plurality of cylinder protrusions 212. The plurality of cylinder grooves 211 are arranged at intervals in the circumferential direction of the rotating cylinder shaft 210, and the plurality of cylinder protrusions 212 are arranged at intervals in the circumferential direction of the rotating cylinder shaft 210. Each cylinder protrusion 212 is inserted into the corresponding cylinder groove 211, and there is a rotation gap 213 between each cylinder protrusion 212 and the corresponding cylinder groove 211 on the side wall in the circumferential direction of the rotating cylinder shaft 210.

[0094] It is understood that the two adjacent rotating cylinder shafts 210 can be connected by a transmission through the cylinder groove 211 and the cylinder protrusion 212. Furthermore, the configuration of the rotation gap 213 allows each blade 200 to rotate synchronously in one direction, and in the direction from the first air duct plate 410 to the second air duct plate 420, each blade 200 rotates sequentially with a delay, so that the tilt directions of the blades 220 on each blade 200 are inconsistent while rotating synchronously. Therefore, the wall-mounted air conditioner indoor unit of this embodiment can have multiple air outlet modes. One of these air outlet modes is a natural wind mode, specifically: when the multiple blades 200 are in a state where the tilt directions of the blades 220 are inconsistent and they have stopped rotating, the airflow from the different parts of the outlet 110 in the lateral direction flows in inconsistent directions. That is, the airflow is turbulent at this time, more like a natural wind, which can give the user a gentler blowing experience, reduce the user's direct blowing sensation, and improve the user experience. Another air outlet mode is the oscillating airflow mode, which involves multiple oscillating blades 200 rotating with their blades 220 tilted in the same or different directions. The airflow is intermittently discharged from the air outlet 110, thus intermittently blowing into the workspace, reducing the user's direct airflow sensation. There is also a directional airflow mode, where the blades 220 of the multiple oscillating blades 200 are tilted in the same direction, resulting in a directional airflow, achieving directional airflow (e.g., airflow directed to the left or right). Of course, the airflow modes achievable by the shaft protrusion 212, shaft groove 211, and rotation gap 213 are not limited to those described above, and will not be further elaborated here. However, any airflow mode achievable by this structure in any indoor air conditioning unit should be considered within the protection scope of this utility model.

[0095] Reference Figure 5 and Figure 6 In this embodiment, each driving protrusion 550 and the corresponding driving groove 540 have a driving gap 560 between the sidewalls of the rotating cylinder shaft 210 in the circumferential direction.

[0096] It should be understood that the configuration of the drive clearance 560 can cause the drive motor 510 to drive the swing blade 200 to rotate when rotating in one direction, and to delay driving the swing blade 200 to rotate when rotating in another direction, so as to adapt to the air supply mode formed by the transmission and rotation between the swing blades 200, and facilitate the configuration of the swing blades 200 in various states or operating modes.

[0097] Reference Figure 12 In this embodiment, the rotating cylinder shaft 210 and the support shaft core 300 are in clearance fit.

[0098] It should be understood that the rotating cylinder shaft 210 and the support shaft core 300 are configured with a clearance fit so that each swing blade 200 can rotate relative to the support shaft core 300. This ensures that the force required to drive each swing blade 200 is reduced, the rotational flexibility of each swing blade 200 is ensured, and the multiple swing blades 200 can be converted into a state where each blade 220 has a different tilt angle, thus ensuring the operation of the aforementioned natural wind mode of the air conditioning indoor unit.

[0099] Reference Figure 12 In this embodiment, the support shaft core 300 is made of plastic material, and the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 is greater than or equal to 0.15mm.

[0100] Understandably, because the surface of plastic is difficult to process to a very fine precision, the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 is configured to be greater than or equal to 0.15mm. This ensures the fitting precision between the support shaft core 300 and the rotating cylinder shaft 210, allowing each rotating cylinder shaft 210 to rotate relative to the support shaft core 300, thus ensuring the normal operation of the oscillating blades 200. Simultaneously, limiting the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 to greater than or equal to 0.15mm prevents excessive clearance between the rotating cylinder shaft 210 and the support shaft core 300, which could cause the oscillating blades 200 to wobble on the support shaft core 300, ensuring the stability of the operation or air delivery of each oscillating blade 200 and guaranteeing the user experience.

[0101] Reference Figure 12 In this embodiment, the support shaft core 300 is made of plastic. The difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 is greater than or equal to 0.2 mm. This ensures that while each rotating cylinder shaft 210 can rotate relative to the support shaft core 300, the fit between the support shaft core 300 and the rotating cylinder shaft 210 is optimized, guaranteeing the normal operation of the oscillating blades 200. Furthermore, limiting the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 to greater than or equal to 0.2 mm prevents excessive clearance between the rotating cylinder shaft 210 and the support shaft core 300, which could cause the oscillating blades 200 to wobble on the support shaft core 300. This ensures the stability of the operation or airflow of each oscillating blade 200, guaranteeing a superior user experience.

[0102] Reference Figure 12 In this embodiment, the support shaft core 300 is made of metal, and the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 is greater than or equal to 0.05 mm.

[0103] Understandably, since metal surfaces can achieve relatively fine precision, configuring the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 to be greater than or equal to 0.05mm ensures the fitting precision between the support shaft core 300 and the rotating cylinder shaft 210, allowing each rotating cylinder shaft 210 to rotate relative to the support shaft core 300 and ensuring the normal operation of the oscillating blades 200. Simultaneously, limiting the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 to greater than or equal to 0.05mm avoids excessive clearance between the rotating cylinder shaft 210 and the support shaft core 300, which could cause the oscillating blades 200 to wobble on the support shaft core 300, ensuring the stability of the operation or air delivery of each oscillating blade 200 and guaranteeing the user experience.

[0104] Reference Figure 12 In this embodiment, the support shaft core 300 is made of metal. The difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 is greater than or equal to 0.1 mm. This ensures that while each rotating cylinder shaft 210 can rotate relative to the support shaft core 300, the fit between the support shaft core 300 and the rotating cylinder shaft 210 is optimized, guaranteeing the normal operation of the oscillating blades 200. Furthermore, limiting the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 to greater than or equal to 0.1 mm prevents excessive clearance between the rotating cylinder shaft 210 and the support shaft core 300, which could cause the oscillating blades 200 to wobble on the support shaft core 300. This ensures the stability of the operation or airflow of each oscillating blade 200, guaranteeing a superior user experience.

[0105] Reference Figure 12 In this embodiment, both the rotating cylinder shaft 210 and the support shaft core 300 are made of plastic, and the outer diameter M of the support shaft core 300 is greater than or equal to 3mm, and the inner diameter L of the rotating cylinder shaft 210 is greater than or equal to 5mm.

[0106] It should be understood that plastic has relatively low strength and toughness. Therefore, in order to ensure the operating strength of each swing blade 200 and the support shaft core 300, and to ensure the normal operation of the swing blade 200 and the support shaft core 300, the outer diameter M of the support shaft core 300 can be configured to be greater than or equal to 3mm, and the inner diameter L of the rotating cylinder shaft 210 can be configured to be greater than or equal to 5mm.

[0107] Reference Figure 12 In this embodiment, both the rotating cylinder shaft 210 and the support shaft core 300 are made of plastic material, and the outer diameter M of the support shaft core 300 is greater than or equal to 4mm, and the inner diameter L of the rotating cylinder shaft 210 is greater than or equal to 6mm, so as to further optimize the operating strength of each swing blade 200 and the support shaft core 300, and further ensure the normal operation of the swing blade 200 and the support shaft core 300.

[0108] Reference Figure 12 In this embodiment, the material of the rotating cylinder shaft 210 includes aluminum alloy, carbon steel or glass fiber, the material of the supporting shaft core 300 includes aluminum alloy, carbon steel or glass fiber, and the outer diameter M of the supporting shaft core 300 is greater than or equal to 1 mm, and the inner diameter L of the rotating cylinder shaft 210 is greater than or equal to 3 mm.

[0109] It is understandable that when the material of the rotating cylinder shaft 210 is a high-strength material such as aluminum alloy, carbon steel, or glass fiber, and the material of the support shaft core 300 includes high-strength materials such as aluminum alloy, carbon steel, or glass fiber, each rotating cylinder shaft 210 and support shaft core 300 can have greater strength and toughness even when they are relatively thin. Therefore, the outer diameter M of the support shaft core 300 is configured to be greater than or equal to 1 mm, and the inner diameter L of the rotating cylinder shaft 210 is configured to be greater than or equal to 3 mm, so as to ensure the operating strength of each swing blade 200 and support shaft core 300 and ensure the normal operation of the swing blade 200 and support shaft core 300.

[0110] Reference Figure 12 In this embodiment, the material of the rotating cylinder shaft 210 includes high-strength materials such as aluminum alloy, carbon steel, or glass fiber, and the material of the supporting shaft core 300 may include high-strength materials such as aluminum alloy, carbon steel, or glass fiber. The outer diameter M of the supporting shaft core 300 is greater than or equal to 2 mm, and the inner diameter L of the rotating cylinder shaft 210 is greater than or equal to 4 mm, so as to further ensure the operating strength of each swing blade 200 and the supporting shaft core 300, and further ensure the normal operation of the swing blade 200 and the supporting shaft core 300.

[0111] Reference Figure 12 In this embodiment, the wall thickness T of the rotating cylinder shaft 210 is greater than or equal to the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 and is less than or equal to 2 mm.

[0112] It is understandable that the wall thickness T of the rotating cylinder shaft 210 is configured to be greater than or equal to the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 and less than or equal to 2mm, so as to ensure the strength of each blade shaft and further ensure the operating strength of the swing blade 200. At the same time, within this range and within the range defined by the aforementioned embodiments, the outer diameter M of the rotating cylinder shaft 210 can be set as small as possible to reduce the restrictive effect of the rotating cylinder shaft 210 on the airflow, increase the airflow rate, and ensure the user's experience.

[0113] Reference Figure 12 In this embodiment, the wall thickness T of the rotating cylinder shaft 210 is greater than or equal to twice the difference between the inner diameter L of the rotating cylinder shaft 210 and the outer diameter M of the support shaft core 300 and less than or equal to 1 mm, so as to make the running strength of the swing blade 200 optimal and further reduce the restrictive effect of the rotating cylinder shaft 210 on the airflow.

[0114] In this embodiment, both the rotating cylinder shaft 210 and the support shaft core 300 are made of plastic, and grease is applied between the rotating cylinder shaft 210 and the support shaft core 300 to ensure the smoothness and stability of the rotation of the oscillating blade 200 around the support shaft core 300, to ensure the stability of the oscillating blade 200 in guiding the airflow direction, and to ensure the user's experience.

[0115] In addition, the grease is a long-life grease, such as complex lithium-based grease, polyurea-based grease, bentonite grease, silicone-based grease, fluorine grease, and fully synthetic high-temperature grease, in order to reduce the number of maintenance operations on the oscillating blade 200 and the support shaft 300 and improve the user experience.

[0116] In this embodiment, the support shaft core 300 is made of metal, and the rotating cylinder shaft 210 is made of self-lubricating composite material, such as polyformaldehyde (POM) or nylon (PA), to ensure the smoothness and stability of the rotation of the oscillating blade 200 around the support shaft core 300, the stability of the oscillating blade 200 in guiding the airflow direction, and the user experience.

[0117] In this embodiment, the metal material used in the previous embodiments can be aluminum alloy, titanium alloy, magnesium alloy, carbon steel, etc. The plastic used in the previous embodiments can be polyethylene, polypropylene, polyvinyl chloride, etc.

[0118] Reference Figures 1 to 12 In this embodiment, when assembling the oscillating blades 200 and the support shaft core 300, the rotating cylinder shafts 210 of multiple oscillating blades 200 can be first sleeved on the support shaft core 300. Then, the fixing sleeve 310 and fixing block 311 are first sleeved onto the support shaft core 300, and then the support shaft is configured with the fixing sleeve 310 and fixing block 311 and inserted into the fixing groove 4211. Next, the drive shaft sleeve 530 is sleeved on the support shaft core 300 and connected to the rotating cylinder shaft 210 (of the oscillating blades 200) provided on the adjacent first air duct plate 410. Then, the drive connector 520 is passed through the first air duct plate 410 and connected to the drive shaft sleeve 530. Finally, the motor shaft is connected to the drive shaft sleeve 530, and the drive motor 510 is connected to the side of the first air duct plate 410 facing away from the air outlet duct 120.

[0119] Alternatively, the rotating cylinder shafts 210 of multiple oscillating blades 200 can be first sleeved onto the support shaft core 300. Then, the fixing sleeve 310 and fixing block 311 are first sleeved onto the support shaft core 300, and then the support shaft with the fixing sleeve 310 and fixing block 311 is inserted into the fixing groove 4211. Then, the drive connector 520 is passed through the first air duct plate 410, the motor shaft is connected to the drive shaft sleeve 530, and the drive motor 510 is connected to the side of the first air duct plate 410 facing away from the air outlet duct 120. Finally, after the drive shaft sleeve 530 is fitted onto the support shaft core 300, the drive shaft sleeve 530 is pushed relative to the support shaft core 300 toward the end of the support shaft core 300 connected to the second air duct plate 420, so as to compress the limiting spring 600 through each rotating cylinder shaft 210. As a result, the drive shaft sleeve 530 and the entire drive shaft sleeve 530 will move toward the end of the support shaft core 300 connected to the second air duct plate 420, so as to make room for a certain space at the end of the support shaft core 300 where the drive shaft sleeve 530 is fitted. Then the drive shaft sleeve 530 and the drive connector 520 are aligned and the drive shaft sleeve 530 is released.

[0120] In summary, both the support shaft core 300 and the swing blades 200 can be quickly and stably assembled onto the indoor unit of the air conditioner, improving the assembly efficiency of the indoor unit.
