The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0037] In order to solve the problem of low air blowing efficiency of air conditioners in the prior art, the present application provides a grille assembly, a grille device and an air conditioner.

[0038] like Figure 1 and Figure 2As shown, the grille assembly includes a frame 10, an air gathering assembly 20, and an air inlet assembly 30. The frame 10 is used to be arranged at the air inlet, and the frame 10 has an installation space. The air gathering assembly 20 is arranged in the installation space. The air inlet assembly 30 is arranged around the air gathering assembly 20, and an air gathering channel is formed between the inner wall of the air inlet assembly 30 and the air gathering assembly 20, so that the air flow flows into the air inlet through the air gathering channel. The inner side wall of the air gathering assembly 20 has a plurality of guide grooves 22, and the plurality of guide grooves 22 are arranged around the preset axis of the air gathering channel, so that at least part of the air flow flowing through the air gathering channel flows out along the guide grooves 22.

[0039] Applying the technical solution of this embodiment, the frame 10 of the grille assembly is used to be set at the air inlet, and the frame 10 has an installation space. The wind gathering assembly 20 is set in the installation space. The air inlet assembly 30 is arranged around the wind gathering assembly 20, and a wind gathering channel is formed between the inner wall of the air inlet assembly 30 and the wind gathering assembly 20, so that the air flow flows into the air inlet through the wind gathering channel. Among them, the inner side wall of the wind gathering assembly 20 has a plurality of guide grooves 22, and the plurality of guide grooves 22 are arranged around the preset axis of the wind gathering channel, so that at least part of the air flow flowing through the wind gathering channel flows out along the guide grooves 22. In this way, when the air conditioner is started, the air flow enters the air inlet through the wind gathering channel, ensuring the air intake reliability of the air conditioner. At the same time, during the flow of air, part of the air flows to the air inlet through the guide groove 22, so that the air can enter the interior of the air conditioner more evenly, avoiding the entire air flow from entering the air inlet from the wind gathering channel, and avoiding the turbulence of the air flow when the air flow rate is too high, thereby improving the blowing efficiency and heat exchange efficiency of the air conditioner, and thus solving the problem of low blowing efficiency of the air conditioner in the prior art.

[0040] In this embodiment, the frame 10 is rectangular and is made of plastic or metal.

[0041] In this embodiment, the preset axis is the central axis of the wind gathering component 20 .

[0042] like Figure 1 and Figure 2 As shown, the air concentrating assembly 20 includes multiple air concentrating structures 21, which are spaced apart around a predetermined axis to divide the air concentrating channel into multiple sub-air concentrating channels 23 arranged around the predetermined axis. In this way, the multiple air concentrating structures 21 subdivide the air concentrating channel into multiple sub-air concentrating channels 23, allowing the airflow to be more finely converged and guided, reducing the disorder of the airflow when it enters, optimizing the flow path of the airflow, and further ensuring the air intake efficiency of the air conditioner.

[0043] like Figure 2 As shown, along the Figure 2In the direction of the air flow, the multiple air collecting structures 21 rotate counterclockwise, so that the air collecting assembly 20 forms a spiral air inlet shape, achieving the convergence of the air flow and ensuring the air intake efficiency of the air conditioner.

[0044] Specifically, two adjacent wind-collecting structures 21 are arranged at an angle of 90°.

[0045] In this embodiment, the number of wind gathering structures 21 is four.

[0046] like Figure 2 As shown, the wind concentrating structure 21 includes interconnected first and second wind concentrating portions 211, 212. The first and second wind concentrating portions 211, 212 are arranged at an angle to each other, and the second wind concentrating portion 212 has a guide groove 22. The ends of the multiple first wind concentrating portions 211 facing the predetermined axis are interconnected, while the ends of the multiple second wind concentrating portions 212 facing away from the predetermined axis are connected to the air inlet assembly 30, forming a swastika-shaped structure. This arrangement of the multiple first wind concentrating portions 211 interconnected and the multiple second wind concentrating portions 212 connected to the air inlet assembly 30 ensures the interconnection of the multiple wind concentrating structures 21 and the connection between the multiple wind concentrating structures 21 and the air inlet assembly 30, ensuring a stable connection between the wind concentrating assembly 20 and the air inlet assembly 30. Furthermore, the first and second wind concentrating portions 211, 212 not only separate the wind concentrating channels, but also give the wind concentrating assembly 20 a traditional window lattice appearance, creating a unique visual effect for the grille assembly and ensuring its aesthetically pleasing appearance. At the same time, the above setting further limits the setting position of the guide groove 22, so that the second wind collecting portion 212 can disperse the airflow on the one hand, ensuring the smooth flow of the airflow; on the other hand, it can also ensure the structural rigidity of the wind collecting structure 21 and ensure the structural stability of the wind collecting structure 21.

[0047] In this embodiment, the angle between the first air concentrating portion 211 and the second air concentrating portion 212 is 90°.

[0048] like Figure 2As shown, the second air concentrating portion 212 is columnar, and the second air concentrating portion 212 has a guide slope 2121. Along the flow direction of the airflow, the extension direction of the guide slope 2121 is set at an angle to the flow direction of the airflow to guide the airflow. Among them, the guide groove 22 is set on the guide slope 2121. In this way, the setting method of the air guide slope ensures that the sub-air concentrating channel 23 is miniaturized along the direction of the airflow entering, so that the sub-air concentrating channel 23 can converge and accelerate the flow of the guided airflow, accelerate the flow speed of the airflow, ensure that the airflow is dispersed and transported by multiple sub-air concentrating channels 23, and also ensure the airflow delivery rate, thereby improving the air intake efficiency of the air conditioner; on the other hand, it can also guide the airflow to a certain extent, ensuring the reliability of the flow direction of the airflow. At the same time, the guide grooves 22 are arranged on the guide slope 2121 to realize the rotational arrangement of multiple guide grooves 22, which can guide and divert the airflow entering different sub-wind-gathering channels 23, further reducing the probability of airflow turbulence and improving the flow smoothness of the airflow.

[0049] In this embodiment, the guide slope 2121 is arranged to be biased toward the sub-wind focusing channel 23, and the angle between the guide slope 2121 and the flow direction of the airflow is set to be 30° to 60°.

[0050] In this embodiment, the guiding slope 2121 is arranged in a parallelogram shape. Two guiding grooves 22 are provided on one guiding slope 2121 . The two guiding grooves 22 are spaced apart along the length direction of the guiding slope 2121 .

[0051] like Figure 1 As shown, the grille assembly also includes a connecting assembly 40, one end of which is connected to the air inlet assembly 30, and the other end of which is connected to the frame 10. An air inlet channel is formed between the connecting assembly 40, the outer wall of the air inlet assembly 30, and at least a portion of the frame 10. Thus, the connecting assembly 40 connects the air inlet assembly 30 to the frame 10, ensuring the structural stability of the air inlet assembly 30 and the air collection assembly 20, reducing the noise of airflow entering the air conditioner, and ensuring comfortable use of the air conditioner. At the same time, the air inlet channel expands the way airflow enters the air inlet, further optimizing the airflow path, dispersing the airflow entering the air inlet, and ensuring stable and smooth airflow.

[0052] like Figure 1As shown, the air inlet assembly 30 includes multiple air inlet structures 31, which are sequentially connected around a predetermined axis. The second air concentrating portion 212 is connected to two adjacent air inlet structures 31. The connecting assembly 40 includes multiple connecting structures 41, which are arranged one-to-one with the multiple air inlet structures 31 to divide the air inlet channel into multiple sub-air inlet channels 32. The arrangement of the multiple air inlet structures 31 creates a spiral structure around the predetermined axis, forming a spiral airflow channel between the air inlet channel and the air concentrating channel. This allows air to enter the air inlet channel in a spiral pattern, increasing the orderliness and speed of the airflow. Furthermore, the arrangement of the multiple sub-air inlet channels 32 disperses the airflow entering the air inlet channel, further improving airflow stability. Furthermore, the arrangement of the multiple connecting structures 41 increases the connection area between the air inlet assembly 30 and the frame 10, ensuring the stability of the connection between the air inlet assembly 30 and the air concentrating assembly 20, reducing air intake noise from the grille assembly, and improving user comfort.

[0053] In this embodiment, the air inlet structure 31 is arranged in a columnar shape.

[0054] In this embodiment, the number of air inlet structures 31 is four.

[0055] It should be noted that the number of air inlet structures 31 can be adjusted according to working conditions and usage requirements. Optionally, the number of air inlet structures 31 is two, three, six, eight, nine, or more.

[0056] like Figure 1As shown, the air inlet structure 31 includes a first air inlet 311, a second air inlet 312, and a third air inlet 313, which are connected in sequence. The second air inlet 312 is located between the first air inlet 311 and the third air inlet 313. The end of the first air inlet 311 away from the second air inlet 312 is connected to the third air inlet 313 of the adjacent air inlet structure 31, and the end of the third air inlet 313 away from the second air inlet 312 is connected to the first air inlet 311 of the adjacent air inlet structure 31. The first air inlet 311 and the second air inlet 312 are arranged at an angle, and the second air inlet 312 and the third air inlet 313 are arranged at an angle. In this way, the air inlet structure 31 is connected to the adjacent air inlet structure 31 through the first air inlet 311 and the third air inlet 313. Furthermore, the angles between the first air inlet 311, the second air inlet 312, and the third air inlet 313 create a non-linear shape for the air inlet structure 31. This creates a traditional window lattice-like appearance, complementing the air collection structure 21. This enhances the aesthetic appeal of the grille assembly and enhances its visual appeal. Furthermore, the unique shape of the air inlet structure 31 creates a unique shape for the air inlet passage, optimizing the airflow path and ensuring airflow stability.

[0057] In this embodiment, the first air inlet portion 311 and the second air inlet portion 312 are arranged at 90 degrees, and the second air inlet portion 312 and the third air inlet portion 313 are arranged at 90 degrees.

[0058] In this embodiment, the connecting structure 41 is connected to the third air inlet portion 313 .

[0059] Optionally, the connection structure 41 and the third air inlet portion 313 are integrally formed.

[0060] like Figure 1As shown, the grille assembly also includes a reinforcement assembly 50, which includes a first reinforcement structure 51 and a second reinforcement structure 52. One end of the first reinforcement structure 51 is connected to the second air inlet 312, and the other end is connected to the frame 10. One end of the second reinforcement structure 52 is connected to the connecting structure 41, and the other end is connected to the frame 10. In this way, the first reinforcement structure 51 connects the second air inlet 312 to the frame 10, and the second reinforcement structure 52 connects the connecting structure 41 to the frame 10. This ensures the stability of the connections between the air inlet structure 31 and the connecting structure 41 and the frame 10, improves the vibration attenuation rate of the grille assembly, and further prevents noise generated by the grille assembly due to structural instability during the air intake process of the air conditioner, further reducing the air intake noise of the air conditioner and improving user comfort. Furthermore, the reinforcement assembly 50 helps differentiate the air intake channel, further dispersing the airflow entering the air intake channel, optimizing the airflow distribution, and helping to improve the air intake efficiency of the air conditioner. At the same time, the reinforcement component 50 can also form a traditional window lattice shape together with the air inlet component 30, the wind collecting component 20 and the connecting component 40, so that the traditional window lattice pattern is combined with the modern air-conditioning structure, thereby enhancing the product's cultural connotation and appearance design, and further enhancing the aesthetics of the grille component.

[0061] The present application also provides a grille device comprising at least two grille assemblies and a rotating shaft. The at least two grille assemblies are sequentially connected along a first predetermined direction. Each grille assembly comprises multiple grille assemblies, each of which is sequentially connected along a second predetermined direction, with the first predetermined direction and the second predetermined direction being arranged at an angle. A rotating shaft is disposed between two adjacent grille assemblies to allow the two adjacent grille assemblies to rotate about the rotating shaft. The grille assemblies are the aforementioned grille assemblies. This connection of the multiple grille assemblies provides a more stylish overall grille device and allows the grille device to be adjusted in length to accommodate air conditioners of varying sizes and specifications, thereby enhancing the versatility of the grille device and ensuring air intake efficiency for air conditioners of varying sizes and specifications. Furthermore, the adjacent grille assemblies can be rotated via the rotating shaft, enabling personnel to open the air inlet through the adjacent grille assemblies when performing maintenance and cleaning on the interior of the air conditioner. This reduces the difficulty and simplifies the disassembly and assembly process for personnel, thereby improving disassembly and assembly efficiency.

[0062] like Figure 4 As shown, the first preset direction is the longitudinal direction of the drawing, and the second preset direction is the transverse direction of the drawing.

[0063] like Figure 3As shown, the present application also provides an air conditioner, which includes a housing 60 and a grille device. The housing 60 has an air inlet. A mounting assembly 70 is arranged at the air inlet, and the mounting assembly 70 includes two mounting structures 71. One end of the grille device is connected to one of the mounting structures 71, and the other end of the grille device is connected to the other mounting structure 71. The grille device is the above-mentioned grille device. In this way, the mounting assembly 70 is connected to the grille device through the mounting structure 71. The staff realizes the installation of the grille device at the air inlet of the housing 60 by connecting the grille device to the mounting assembly 70, thereby ensuring the installation reliability of the grille device.

[0064] like Figure 3 and Figure 5 As shown, the housing 60 also has a first connecting portion and a first magnetic portion. The air conditioner also includes a second connecting portion 80 and a second magnetic portion 90. The second connecting portion 80 is disposed on one of the mounting structures 71. One of the second connecting portion 80 and the first connecting portion is a protrusion, and the other of the second connecting portion 80 and the first connecting portion is a recess. The protrusion extends into the recess to engage with the recess. The second magnetic portion 90 is disposed on the other mounting structure 71 and is magnetically connected to the first magnetic portion. Thus, when a worker needs to install the grille device at the air inlet of the air conditioner housing 60, the worker first engages the second connecting portion 80 on the mounting structure 71 at one end of the grille device with the first connecting portion of the housing 60. Once the second connecting portion 80 is successfully engaged with the first connecting portion, the worker magnetically connects the second magnetic portion 90 on the mounting structure 71 at the other end of the grille device with the first magnetic portion on the housing 60, thereby completing the installation of the grille device. When the staff needs to perform maintenance and cleaning on the inside of the air conditioner, they only need to separate the first magnetic part from the second magnetic part 90 and rotate and fold the multiple grille assemblies to open the air inlet. When the staff needs to disassemble the grille device, they first separate the first magnetic part from the second magnetic part 90, and then separate the second connecting part 80 from the first connecting part, and remove the grille assembly from the air inlet, thereby achieving the disassembly of the grille device, simplifying the disassembly and assembly steps for the staff, reducing the difficulty of the staff's insertion, and improving the staff's work efficiency. At the same time, the setting method of the second connecting part 80 and the second magnetic part 90 allows the grille device to use a dual fixing method of magnetic attraction and snap-on connection during the connection process with the shell 60, thereby improving the connection stability between the grille device and the shell 60 and improving the installation reliability and stability of the grille device.

[0065] In this embodiment, the first connection portion is a recessed portion, and the second connection portion 80 is a protrusion.

[0066] Optionally, the first connecting portion is a protrusion, and the second connecting portion 80 is a recess.

[0067] In this embodiment, the second magnetic attraction portion 90 and the second magnetic attraction portion 90 are both embedded with N35 neodymium iron boron magnets.

[0068] In this embodiment, there are two second connection parts 80 , and the two second connection parts 80 are disposed opposite to each other on the mounting structure 71 .

[0069] In this embodiment, there are two second magnetic portions 90 , and the two second magnetic portions 90 are disposed opposite to each other on the mounting structure 71 .

[0070] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0071] The grille assembly frame is configured to be mounted at the air inlet, and the frame has a mounting space. The air concentrating assembly is disposed within the mounting space. The air inlet assembly is disposed around the air concentrating assembly, and an air concentrating channel is formed between the inner wall of the air inlet assembly and the air concentrating assembly, allowing airflow to flow through the air concentrating channel and into the air inlet. The inner wall of the air concentrating assembly has a plurality of guide grooves, which are arranged around a predetermined axis of the air concentrating channel so that at least a portion of the airflow passing through the air concentrating channel flows out along the guide grooves. Thus, when the air conditioner is started, airflow enters the air inlet through the guide grooves, ensuring reliable air intake for the air conditioner. Furthermore, during airflow, a portion of the airflow flows toward the air inlet through the guide grooves, allowing the airflow to enter the air conditioner more evenly. This prevents the entire airflow from entering the air inlet through the guide channel and avoids airflow turbulence caused by excessive airflow velocity. This improves the air blowing efficiency and heat exchange efficiency of the air conditioner, thereby resolving the low air blowing efficiency problem of air conditioners in the prior art.
