Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to a swing air guide mechanism, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] With economic development and global warming, the living and working environments on which humans depend for survival are becoming increasingly harsh. People's demand for air conditioning is growing, and the demand for high-quality air conditioners with high comfort and low noise is even greater. Airflow and noise are a pair of mutually restrictive factors: high airflow means high noise, which in turn indicates a better comfort experience, but high noise means a poorer experience; conversely, low airflow means low noise, which in turn indicates a better noise experience but a poorer comfort experience.

[0003] Currently, wall-mounted air conditioners generally require swing blades to change the direction of airflow, achieving left-right swing. However, due to structural and space limitations, the swing blades are typically designed inside the air duct. This affects the airflow path, increasing airflow resistance, reducing air volume, and increasing noise. Additionally, wall-mounted air conditioners often require air deflectors at the outlet for vertical airflow, located outside the duct. This design, combining left-right swing with vertical airflow from the swing blades, makes the structure complex. Furthermore, in related technologies, the swing blades are usually placed on the inner side of the air deflector near the duct, which can easily generate noise during airflow, resulting in poor comfort.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] Please refer to Figures 1 to 14This invention provides a sweeping air guiding mechanism for installation at the air outlet 100 of an indoor air conditioning unit. The sweeping air guiding mechanism includes: a plurality of sweeping air guiding components 10, installed on the outer side of the air outlet 100; a plurality of first connecting rods 20, which are spaced apart along the extension direction of the air outlet 100; the plurality of sweeping air guiding components 10 are connected one-to-one with the first ends 201 of the plurality of first connecting rods 20; each sweeping air guiding component 10 is rotatably arranged about a first axis relative to the corresponding first connecting rod 20; the second ends 202 of the plurality of first connecting rods 20 are rotatably connected to the indoor air conditioning unit about a second axis, so as to drive the plurality of sweeping air guiding components 10 to rotate about the second axis; wherein, the second axis extends along the distribution direction of the plurality of first connecting rods 20, and the first axis and the second axis are set at a preset angle. With the above configuration, the air-sweeping guide component 10 can rotate around the first axis and the second axis respectively to achieve left-right and up-down air sweeping. In this way, there is no need to set up an air guide plate for up-down rotation, which reduces the use of parts and saves production costs. Furthermore, multiple air-sweeping guide components 10 are all set on the outside of the air outlet, so that the air-sweeping guide components 10 will not affect the airflow during the movement. Thus, the indoor unit of the air conditioner will not generate noise when it vents air and can ensure the air volume, thereby improving the comfort of the air outlet.

[0046] In order to achieve the connection between the air sweeping and air guiding component 10 and the first connecting rod 20, each air sweeping and air guiding component 10 is provided with a first connecting part 11, and each first end 201 of the first connecting rod 20 is provided with a second connecting part 21. One of the first connecting part 11 and the second connecting part 21 includes a first rotating shaft 110, and the other of the first connecting part 11 and the second connecting part 21 includes a first slot 210. The first rotating shaft 110 is rotatably disposed in the first slot 210, and the central axis of the first rotating shaft 110 is arranged parallel to the first axis.

[0047] This application provides a first slot 210 with a slot opening, through which the first rotating shaft 110 passes and enters the interior of the first slot 210, thus facilitating the connection between the first rotating shaft and the first connecting rod 20.

[0048] Specifically, such as Figure 10 As shown, the first slot 210 includes a first slot section and a second slot section connected to each other. The end of the first slot section away from the second slot section has a slot opening, through which the first rotating shaft 110 passes into the second slot section. Along the distribution direction from the first slot section to the second slot section, the cross-sectional area of ​​the first slot section gradually decreases. The cross-section of the first slot section is perpendicular to the extension direction of the first connecting rod 20. The first slot section serves as a transition point, facilitating the entry of the first rotating shaft into the second slot section.

[0049] like Figure 2 As shown, the first connecting part 11 includes a first mounting groove 111, and the first rotating shaft 110 is installed in the first mounting groove 111; the second connecting part 21 includes a connecting block 211, and a first slot 210 is provided on the connecting block 211 so that after the first rotating shaft 110 passes through the first slot 210, the connecting block 211 is located in the first mounting groove 111, so that the connection between the first connecting rod 20 and the air sweeping and guiding component 10 is compact.

[0050] Specifically, the air-sweeping and air-guiding component 10 is provided with a plurality of first connecting protrusions 1110, which together form a first mounting groove 111.

[0051] In this application, there are two first connecting protrusions 1110, which are arranged opposite to each other. The two ends of the first rotating shaft 110 are respectively connected to the two first connecting protrusions 1110, and the connecting block 211 is located between the two first connecting protrusions 1110.

[0052] In the embodiments of this application, the air-sweeping and air-guiding mechanism further includes: a second connecting rod 30, wherein the second ends 202 of a plurality of first connecting rods 20 are all transmittedly connected to the second connecting rod 30, and the plurality of first connecting rods 20 are spaced apart along the length direction of the second connecting rod 30; wherein the second connecting rod 30 is movably arranged along its extension direction to drive the first ends 201 of the plurality of first connecting rods 20 to move, and to drive the plurality of air-sweeping and air-guiding components 10 to rotate around a first axis; wherein the second connecting rod 30 is rotatably arranged around a second axis to drive the plurality of first connecting rods 20 and the plurality of air-sweeping and air-guiding components 10 to rotate around the second axis; wherein the central axis of the second connecting rod 30 is parallel to the second axis. Through the above-described arrangement of the second connecting rod 30, the synchronous movement of the plurality of air-sweeping and air-guiding components 10 can be ensured, so that the plurality of air-sweeping and air-guiding components guide the air outlet in the same direction, and mutual interference between adjacent air-sweeping and air-guiding components 10 can be avoided.

[0053] To achieve the transmission connection between multiple first connecting rods 20 and second connecting rods 30, each first connecting rod 20 has a third connecting portion 22 at its second end 202, and the second connecting rod 30 has multiple fourth connecting portions 31. The multiple fourth connecting portions 31 are spaced apart along the extension direction of the second connecting rod 30, and the third connecting portions 22 and the multiple fourth connecting portions 31 of the multiple first connecting rods 20 are connected one-to-one. Among them, one of the third connecting portions 22 and the fourth connecting portions 31 has a second rotating shaft 220, and the other of the third connecting portions 22 and the fourth connecting portions 31 has a second slot 310. The second rotating shaft 220 is rotatably disposed in the second slot 310. The central axis of the second rotating shaft 220 is parallel to the first axis.

[0054] like Figure 10As shown, the third connecting part 22 includes a connecting seat 221, which has a second mounting groove 2210. The second rotating shaft 220 is installed in the second mounting groove 2210. The fourth connecting part 31 has a second slot 310. After the second rotating shaft 220 passes through the second slot 310, the second connecting rod 30 is located in the second mounting groove 2210. With the above arrangement, the connection structure between the first connecting rod 20 and the second connecting rod 30 can be made compact.

[0055] Specifically, the connecting seat 221 includes two opposing protrusions and a connecting plate. The connecting plate is located between and connected to both protrusions. The two protrusions and the connecting plate form a U-shaped second mounting groove 2210. The second connecting rod 30 is a connecting plate, and the two protrusions are located on both sides of the thickness direction of the second connecting rod 30. Through the above arrangement, the two protrusions can play a certain limiting role in the rotation of the second connecting rod 30 around its axis, so as to prevent the second connecting rod 30 from rotating excessively and ensure the reliability of the rotation of the second connecting rod 30.

[0056] Specifically, the second rotating shaft 220 is located on the side of the protrusion away from the connecting plate.

[0057] like Figure 2 and Figure 4 As shown, the air-sweeping and air-guiding mechanism also includes a drive assembly 40, which is installed on the outside of the air outlet 100. In this way, the drive assembly 40 will not affect the airflow, thereby preventing the indoor unit of the air conditioner from generating noise when it vents, reducing the airflow resistance, and increasing the airflow volume. In order to realize the automatic rotation of the air-sweeping and air-guiding component 10, the drive assembly 40 includes a first drive structure 41 and a second drive structure 42. The first drive structure 41 is driven to one end of the second connecting rod 30 to drive the second connecting rod 30 to move along its extension direction. The second drive structure 42 is driven to the first drive structure 41 to drive the first drive structure 41 to rotate around the second axis, thereby driving the second connecting rod 30 to rotate around the second axis.

[0058] Specifically, the first drive structure 41 includes a first drive component 410 and a first mounting component 411. The first drive component 410 is mounted on the first mounting component 411, and the first mounting component 411 is rotatably connected to the bottom shell 200 of the indoor unit of the air conditioner. This makes the connection structure between the first drive structure 41 and the indoor unit of the air conditioner stable and reliable, and also makes the rotation of the first mounting component 411 stable. The first drive component 410 is driven to connect with the second connecting rod 30 to drive the second connecting rod 30 to move along its extension direction. The second drive structure 42 includes a second drive component 420, which is mounted on the bottom shell 200. The second drive component 420 is driven to connect with the first mounting component 411 to drive the first mounting component 411 and the first drive component 410 to rotate around the second axis. Thus, since the first drive component 410 is driven to connect with the second connecting rod 30, the rotation of the first drive component 410 around the second axis will also drive the second connecting rod 30 to rotate around the second axis.

[0059] In the embodiments of this application, when the first driving component 410 drives the second connecting rod 30 to move along its extension direction, the second driving component 420 stops operating; when the second driving component 420 starts, the first driving component 410 stops operating. In this way, the reliability of the driving assembly driving the movement of multiple sweeping and guiding components can be guaranteed.

[0060] Specifically, the first drive structure 41 further includes a transmission rod 412, a first drive component 410 being a first drive motor, a first output shaft of the first drive motor being connected to one end of the transmission rod 412, and the other end of the transmission rod 412 being connected to the second connecting rod 30, so that the first drive motor drives the transmission rod 412 to rotate, thereby driving the second connecting rod 30 to move along its extension direction. By setting the transmission rod 412, this application can ensure the movement trajectory of multiple first connecting rods.

[0061] In the embodiments of this application, such as Figure 8 , Figure 9 , Figure 13 and Figure 14 As shown, the second connecting rod 30 includes a connecting rod body 32 and a connecting rod segment 33 connected to each other. The connecting rod segment 33 is provided with a first connecting hole 330. One end of the transmission rod 412 is provided with a fifth connecting part 4120. The fifth connecting part 4120 includes a connecting post and a limiting flange 4121. The limiting flange 4121 is provided at the free end of the connecting post so that after the connecting post passes through the first connecting hole 330, the limiting flange 4121 is limited and engaged with the connecting rod segment 33 of the second connecting rod 30. In this way, the transmission rod 412 can be prevented from coming out of the first connecting hole 330, ensuring the stability and reliability of the connection between the second connecting rod and the transmission rod 412.

[0062] The free end of the connecting column is the end of the connecting column that is away from the transmission rod 412.

[0063] Specifically, the transmission rod 412 is arranged parallel to the plurality of first connecting rods 20, so that during the movement, the movement trajectory of the plurality of first connecting rods 20 is the same as the movement trajectory of the transmission rod 412; and / or, the first mounting component 411 is a first mounting box, the first mounting box has a first mounting cavity 4110, at least a portion of the transmission rod 412 is located in the first mounting cavity 4110, the first drive motor is mounted on the outer wall of the first mounting box, and the first output shaft of the first drive motor passes through the outer wall of the first mounting box and is driven to connect with the transmission rod 412. By setting the transmission rod 412 in the first mounting cavity 4110, the range of movement of the transmission rod 412 can be limited, the transmission rod 412 can be prevented from moving excessively, and the reliability of the movement of the transmission rod 412 can be guaranteed.

[0064] In the embodiments of this application, the transmission rod 412 is arranged parallel to the plurality of first connecting rods 20, and at least a portion of the transmission rod 412 is disposed within the first mounting cavity 4110. In this way, while the movement range of the first mounting cavity is restricted by the inner wall of the first mounting cavity, the movement trajectory of the plurality of first connecting rods 20 is the same as the movement trajectory of the transmission rod 412. Thus, the limiting of the plurality of first connecting rods 20 is also achieved, ensuring the reliability of the movement of the plurality of first connecting rods 20.

[0065] like Figure 8 , Figure 9 and Figure 11 As shown, the inner wall of the first mounting cavity 4110 is provided with a third rotating shaft 4111, and the other end of the transmission rod 412 is provided with a second connecting hole. The second connecting hole includes a first connecting hole section 4122 and a second connecting hole section 4123 that are connected to each other. The first connecting hole section 4122 is sleeved on the third rotating shaft 4111, and the first output shaft of the first drive motor passes through the second connecting hole section 4123.

[0066] Specifically, a first mounting post 414 is provided on the outer wall of the first mounting component 411, and a first mounting plate is provided on the motor body of the first drive motor, so that the first drive motor can be fixed on the first mounting component 411 by fasteners passing through the first mounting post 414 and the first mounting plate.

[0067] Specifically, the first mounting component 411 is provided with a through hole, which is arranged opposite to the third rotating shaft 4111 so that the first output shaft of the first drive motor passes through the through hole and is mounted on the transmission rod. There are multiple first mounting posts 414, which are arranged at intervals around the through hole.

[0068] Specifically, there are two first mounting posts 414, and the distribution direction of the two first mounting posts 414 is set at a preset angle with the first horizontal line.

[0069] like Figure 2 As shown, the second drive structure 42 includes a second mounting component 421, which is fixedly connected to the bottom shell 200. The second drive component 420 is disposed on the second mounting component 421, which is located below the first drive structure 41. The second mounting component 421 and the first mounting component 411 are set at a preset angle. In this way, the second mounting component 421 can support the first drive structure 41, ensuring the structural reliability and stability of the drive assembly 40. When the first mounting component 411 rotates to a predetermined position, the second mounting component 421 can also limit the first mounting component 411, ensuring the reliability of the movement of the multiple sweeping and guiding components 10 from the drive source of the drive assembly. And / or, the second drive component 420 is a second drive motor, and the second output shaft of the second drive motor is connected to the side wall of the second mounting component 421 away from the sweeping and guiding component 10.
