[0002] In a cabinet air conditioner, the air outlet assembly is the main component for air outlet. The left and right louvers in the air outlet assembly are usually driven by a small stepper motor or synchronous motor. Through a gear or linkage mechanism, all louvers move synchronously to automatically adjust the airflow direction.

[0003] The inventors discovered that the left and right sweeping blades in the air outlet assembly of the related technology are prone to detaching from the air outlet frame. Utility Model Content

[0004] The purpose of this utility model is to provide an air outlet assembly that can improve the connection stability between the left and right sweeping blades and the air outlet frame, and prevent the left and right sweeping blades from easily detaching from the air outlet frame.

[0005] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides an air outlet component, comprising: The air outlet frame includes a top plate and a bottom plate spaced apart in the vertical direction. Both the top plate and the bottom plate are provided with shaft holes, and the outer periphery of the shaft holes of the top plate and the bottom plate are provided with disassembly holes. Left and right air sweeping blades, each end of the left and right air sweeping blades is provided with a rotating shaft, and at least one of the two rotating shafts of the left and right air sweeping blades has a limiting protrusion protruding on its outer peripheral wall. The rotating shafts at both ends of the left and right air sweeping blades are respectively engaged with the shaft holes of the top plate and the bottom plate. The limiting protrusion can pass through the disassembly hole and extend out of the top plate or the bottom plate. The left and right sweeping blades can rotate relative to the air outlet frame within a preset angle range under the drive of the drive component to perform sweeping. During the rotation of the left and right sweeping blades within the preset angle range, the limiting protrusions and the disassembly holes are misaligned.

[0006] The above settings effectively prevent the limiting protrusions from coming out of the disassembly holes, improve the connection stability between the left and right sweeping blades and the air outlet frame, and prevent the left and right sweeping blades from easily detaching from the air outlet frame.

[0007] In an optional implementation, the left and right sweeping blades have a first posture, a second posture, and a third posture. The left and right sweeping blades can rotate from the first posture to the second posture by a first angle relative to the air outlet frame along a first direction under the drive of the drive member. The left and right sweeping blades can rotate from the first posture to the third posture by a second angle relative to the air outlet frame along a second direction under the drive of the drive member. The first direction is opposite to the second direction, and the sum of the first angle and the second angle is a preset angle. With the left and right sweeping blades in their first position, the opening direction of the left and right sweeping blades is parallel to that of the air outlet of the air outlet frame, with a preset angle of 80°~100°.

[0008] With the above settings, the sweeping range of the left and right sweeping blades is guaranteed, while also preventing the left and right sweeping blades from easily detaching from the air outlet frame.

[0009] In an optional implementation, the limiting protrusion has gaps with both the top plate and the bottom plate.

[0010] The above settings can prevent friction between the limiting protrusion and the bottom or top plate from affecting the rotation of the left and right sweeping blades, ensuring the smoothness of the rotation of the left and right sweeping blades, and also avoiding additional noise when the left and right sweeping blades rotate.

[0011] In an optional embodiment, a water baffle is provided at one end of the left and right sweeping blades near the bottom plate. The outer peripheral wall of the water baffle is located on the outer periphery of the rotating shaft, and the radial dimension of the water baffle is larger than the radial dimension of the rotating shaft.

[0012] The above settings can effectively prevent condensate from flowing down the shaft hole and then down the outer wall of the shaft.

[0013] In an optional embodiment, a mating protrusion is provided on the side of the bottom plate near the top plate, and the mating protrusion is inserted into the water baffle.

[0014] The above settings ensure efficient connection with the water baffle and further prevent condensate from flowing down the shaft through the shaft hole onto the rotating shaft.

[0015] In an optional embodiment, the water shield and the base plate have a gap in the vertical direction.

[0016] The above settings ensure smooth rotation of the left and right sweeping blades.

[0017] In an optional embodiment, the water shield is also provided with reinforcing ribs, which are connected to the left and right sweeping blades.

[0018] The above-mentioned design can enhance the structural strength of the water barrier.

[0019] In an optional implementation, the air outlet assembly also includes a top panel; The air outlet frame and the top panel are integrally formed, or the air outlet frame and the top panel are detachably connected.

[0020] With the above-described design, the number of parts in the air outlet assembly can be effectively reduced by integrally molding the air outlet frame and the upper panel, improving structural fabrication efficiency. It also prevents condensation caused by air leakage through the gap between the upper panel and the air outlet frame. Furthermore, the detachable connection between the air outlet frame and the upper panel facilitates the assembly and disassembly of the air outlet frame.

[0021] In an optional embodiment, the outer peripheral wall of the air outlet frame is provided with thermal insulation cotton.

[0022] The above settings can reduce the occurrence of condensation on the outer wall of the air outlet frame.

[0023] Secondly, this utility model provides an air conditioner, including an air outlet assembly according to any of the aforementioned embodiments. The air outlet assembly also includes an upper panel, an air outlet provided on the upper panel, an air outlet frame provided on the air outlet, the air outlet frame being disposed on the inner wall of the upper panel, and the air outlet frame also being equipped with upper and lower sweeping blades. The left and right sweeping blades are arranged in the same direction as the opening of the air outlet of the upper and lower sweeping blades. The left and right sweeping blades and / or the upper and lower sweeping blades are located inside the air outlet of the upper panel. When the left and right sweeping blades and the upper and lower sweeping blades are closed, the left and right sweeping blades or the upper and lower sweeping blades are flush with the outer surface of the upper panel.

[0024] The above settings can prevent the air outlet frame from affecting the sweeping range of the left and right sweeping blades and the upper and lower sweeping blades, thereby increasing the sweeping area.

[0025] The beneficial effects provided by this utility model embodiment include: This utility model embodiment provides an air outlet assembly and an air conditioner. The air conditioner includes the aforementioned air outlet assembly, which includes an air outlet frame and left and right sweeping blades. The air outlet frame includes a top plate and a bottom plate spaced apart in a vertical direction.

The left and right sweeping blades can rotate relative to the air outlet frame within a preset angle range to perform sweeping. During the rotation of the left and right sweeping blades within the preset angle range, the limiting protrusions are misaligned with the disassembly holes.

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] The following describes in detail, with reference to the accompanying drawings, the specific structure of an air outlet component provided by this utility model and its corresponding technical effects.

[0036] Please refer to Figures 1-7 The present invention provides a coarse air assembly including an air outlet frame 100 and left and right sweeping blades 200. The air outlet frame 100 includes a top plate 110 and a bottom plate 120 arranged vertically at intervals. Both the top plate 110 and the bottom plate 120 are provided with shaft holes 130, and the outer periphery of the shaft holes 130 in the top plate 110 and the bottom plate 120 are provided with disassembly holes 140. Both ends of the left and right sweeping blades 200 are provided with rotating shafts 210. At least one of the two rotating shafts 210 of the left and right sweeping blades 200 has a limiting protrusion 220 protruding from its outer peripheral wall. The rotating shafts 210 at both ends of the left and right sweeping blades 200 respectively cooperate with the shaft holes 130 of the top plate 110 and the bottom plate 120. The limiting protrusion 220 can pass through the disassembly hole 140 and extend out of the top plate 110 or the bottom plate 120.

[0037] In this embodiment, the left and right sweeping blades 200 can rotate relative to the air outlet frame 100 within a preset angle range to perform sweeping. During the rotation of the left and right sweeping blades 200 within the preset angle range, the limiting protrusion 220 is misaligned with the disassembly hole 140.

[0038] Understandably, after the sweeping blades and the air outlet frame 100 are assembled, the top plate 110 has a limiting protrusion 220 on the side away from the bottom plate 120, and the bottom plate 120 has a limiting protrusion 220 on the side away from the top plate 110. The limiting protrusion 220 can restrict the left and right sweeping blades 200 from moving vertically. During the sweeping process driven by the motor, the limiting protrusion 220 is always misaligned with the disassembly hole 140, which can effectively prevent the limiting protrusion 220 from coming out of the disassembly hole 140. Therefore, even if the left and right sweeping blades 200 move vertically, under the action of the limiting protrusion 220, the rotating shaft 210 cannot pass through the shaft hole 130, and the left and right sweeping blades 200 will not detach from the air outlet frame 100. This improves the connection stability between the left and right sweeping blades 200 and the air outlet frame 100, and prevents the left and right sweeping blades 200 from easily detaching from the air outlet frame 100.

[0039] It should be noted that in this embodiment, the outer peripheral wall of the rotating shaft 210 above the left and right sweeping blades 200 is provided with a limiting protrusion 220, while the outer peripheral wall of the rotating shaft 210 below the left and right sweeping blades 200 is not provided with a limiting protrusion 220.

[0040] Of course, in some alternative embodiments, the outer peripheral walls of the rotating shafts 210 on both the upper and lower sides of the left and right sweeping blades 200 are provided with limiting protrusions 220.

[0041] In detail, the left and right sweeping blades 200 have a first posture, a second posture and a third posture. Under the drive of the driving component, the left and right sweeping blades 200 can rotate relative to the air outlet frame 100 in a first direction from the first posture to the second posture. Under the drive of the driving component, the left and right sweeping blades 200 can rotate relative to the air outlet frame 100 in a second direction from the first posture to the third posture by a second angle. The first direction is opposite to the second direction, and the sum of the first angle and the second angle is a preset angle.

[0042] In this embodiment, when the left and right sweeping blades 200 are in the first posture, they are parallel to the opening direction of the air outlet 410, with a preset angle of 80° to 100°. This means that the left and right sweeping blades 200 can rotate from the first posture to the third posture and vice versa under the drive of the driving component. The rotation angle range between the first and third postures is the preset angle range. In this embodiment, the preset angle is 80° to 100°, which effectively ensures the sweeping range of the left and right sweeping blades 200. Optionally, the preset angle is 90°, and both the first and second angles are 45°.

[0043] As can be seen from the above, in this embodiment, during the rotation of the left and right sweeping blades 200 between the first and third postures, the limiting protrusion 220 and the disassembly hole 140 are misaligned, which can effectively prevent the limiting protrusion 220 from coming out of the disassembly hole 140, so that the left and right sweeping blades 200 can easily detach from the air outlet frame 100.

[0044] In this embodiment, the limiting protrusion 220 has gaps with both the top plate 110 and the bottom plate 120. That is, the upper limiting protrusion 220 has a gap with the top plate 110 in the vertical direction, and the lower limiting protrusion 220 also has a gap with the bottom plate 120 in the vertical direction. This can prevent the friction between the limiting protrusion 220 and the bottom plate 120 or the top plate 110 from affecting the rotation of the left and right sweeping blades 200, ensuring the smoothness of the rotation of the left and right sweeping blades 200, and also avoiding additional noise when the left and right sweeping blades 200 rotate.

[0045] In this embodiment, a water baffle 230 is provided on a section of the left and right sweeping blades 200 near the base plate 120. The outer peripheral wall of the water baffle 230 is located on the outer periphery of the rotating shaft 210. The radial dimension of the water baffle 230 is larger than the radial dimension of the rotating shaft 210. It can be understood that by setting the water baffle 230, condensate can be effectively prevented from flowing down from the shaft hole 130 and down the outer wall of the rotating shaft 210.

[0046] The bottom plate 120 has a mating protrusion 150 on the side near the top plate 110, which is inserted into the water baffle 230. Understandably, the mating protrusion 150 further prevents condensate from flowing down from the shaft hole 130 onto the rotating shaft 210.

[0047] It should be noted that, in order to reduce the contact between the water baffle 230 and the base plate 120 and to avoid friction between the water baffle 230 and the base plate 120 during the rotation of the left and right sweeping blades 200, in this embodiment, there is a gap between the water baffle 230 and the base plate 120 in the vertical direction. This ensures the smoothness of the rotation of the left and right sweeping blades 200.

[0048] Optionally, in some embodiments, to improve the lifespan and structural strength of the water baffle 230, a reinforcing rib 240 is also provided on the water baffle 230, and the reinforcing rib 240 is connected to the left and right sweeping blades 200. That is, the reinforcing rib 240 can be connected to both the water baffle 230 and the left and right sweeping blades 200 at the same time, thereby effectively improving the strength of the water baffle 230.

[0049] In this embodiment, a reinforcing rib 240 is provided on the outer side of the water barrier 230. Of course, in some other embodiments, a reinforcing rib 240 may also be provided on the inner side of the water barrier 230.

[0050] In this embodiment, the air outlet assembly 1 also includes an upper panel 400. It is understood that the air outlet frame 100 is located inside the upper panel 400. It is understood that the upper panel 400 is located at the top of the cabinet unit and covers the entire top area, extending from the front end to the rear to form the top appearance surface of the air conditioner cabinet unit. The air outlet frame 100 is generally located above the front side of the upper panel 400. Generally, the air outlet frame 100 protrudes from the front end of the upper panel 400 or is aligned with the front edge of the upper panel 400.

[0051] Optionally, in some embodiments, the upper panel 400 and the air outlet frame 100 are integrally formed, for example, the upper panel 400 and the air outlet frame 100 can be integrally formed by injection molding. This can effectively reduce the number of parts in the air outlet assembly 1, improve the efficiency of structural fabrication, and also avoid condensation caused by air leakage at the gap between the upper panel 400 and the air outlet frame 100.

[0052] Of course, in some other embodiments, the upper panel 400 and the air outlet frame 100 can also be detachably connected. For example, the upper panel 400 and the air outlet frame 100 can be detachably connected by screws and / or clips, which facilitates the disassembly and assembly of the air outlet frame 100. During transportation, the air outlet frame 100 can be removed.

[0053] Optionally, in some embodiments, to further reduce condensation, the outer peripheral wall of the air outlet frame 100 may be provided with thermal insulation cotton.

[0054] This utility model embodiment also provides an air conditioner, which includes the aforementioned air outlet assembly 1. The air outlet frame 100 of the air outlet assembly 1 is disposed on the inner wall of the upper panel 400, and the air outlet frame 100 is also equipped with upper and lower sweeping blades 300, which are used to swing up and down for vertical air sweeping. The left and right sweeping blades 200 and the upper and lower sweeping blades 300 are arranged along the opening direction of the air outlet 410, and are located within the air outlet 410 of the upper panel 400. When the left and right sweeping blades 200 and the upper and lower sweeping blades 300 are closed, they are flush with the outer surface of the upper panel 400. This effectively prevents the air outlet frame 100 from affecting the sweeping range of the left and right sweeping blades 200 and the upper and lower sweeping blades 300, increasing the sweeping area.

[0055] Of course, air conditioners also include structures such as heat exchangers, compressors, drip trays, and electrical control boxes, which will not be elaborated on here.

[0056] In summary, this utility model embodiment provides an air outlet assembly 1 and an air conditioner. The air conditioner includes the aforementioned air outlet assembly 1, which includes an air outlet frame 100 and left and right sweeping blades 200. The air outlet frame 100 includes a top plate 110 and a bottom plate 120 arranged vertically at intervals. Both the top plate 110 and the bottom plate 120 are provided with shaft holes 130, and the outer periphery of the shaft holes 130 in the top plate 110 and the bottom plate 120 are provided with disassembly holes 140. Both ends of the left and right sweeping blades 200 are provided with rotating shafts 210. The outer peripheral wall of the rotating shafts 210 on the lower side of the left and right sweeping blades 200 is provided with limiting protrusions 220. The rotating shafts 210 at both ends of the left and right sweeping blades 200 respectively cooperate with the shaft holes 130 of the top plate 110 and the bottom plate 120. The limiting protrusions 220 can pass through the disassembly holes 140 and extend out of the top plate 110 or the bottom plate 120. The left and right sweeping blades 200 can rotate relative to the air outlet frame 100 within a preset angle range under the drive of the driving component to perform sweeping. During the rotation of the left and right sweeping blades 200 within the preset angle range, the limiting protrusion 220 is misaligned with the disassembly hole 140. This effectively prevents the limiting protrusion 220 from coming out of the disassembly hole 140, improves the connection stability between the left and right sweeping blades 200 and the air outlet frame 100, and prevents the left and right sweeping blades 200 from easily detaching from the air outlet frame 100.

[0057] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
