Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to an air dissipation component and an air conditioner. Background Technology

[0002] Existing air conditioner indoor units typically disperse airflow through diffuser panels. Specifically, these panels have perforations running along their thickness. When the airflow encounters the diffuser, the small diameter of these perforations limits its distance after it reaches the outlet side of the panel, thus achieving dispersion and a near-zero draft. However, because the airflow only converges once at the inlet and diffuses once at the outlet, its dispersion effect is poor. While complex perforation designs can improve dispersion, they also increase manufacturing complexity. Utility Model Content The first objective of this utility model is to provide a wind dispersing component to solve the technical problem that existing wind dispersing components with good wind dispersing effect are difficult to manufacture.

[0003] The first aspect of this utility model provides an air dispersing component, which includes multiple relatively fixed and stacked air dispersing plates. Each air dispersing plate includes an air dispersing portion. Along the thickness direction of the air dispersing component, the air dispersing portion of each air dispersing plate is at least partially correspondingly arranged. The air dispersing portion is provided with multiple air dispersing holes, and the solid structure of the air dispersing portion has only one layer of material in the thickness direction of the air dispersing plate.

[0004] The beneficial effects of this air diffuser component are: By setting the air diffuser assembly to include multiple relatively fixed air diffuser plates, and ensuring that the air diffuser portion on each air diffuser plate has only one layer of material in the thickness direction, the relatively simple-shaped air diffuser plates can be processed by injection molding. Then, multiple single air diffuser plates are stacked and fixed to form a stacked air diffuser assembly, thus eliminating the need for 3D printing to process the overall air diffuser assembly. This significantly reduces the manufacturing difficulty and cost of the air diffuser assembly, shortens processing time, and improves production efficiency.

[0005] In an optional technical solution, the air diffuser assembly includes a first air diffuser plate and a second air diffuser plate. The first air diffuser plate includes a base plate portion and a limiting sidewall portion disposed at the edge of the base plate portion. At least a portion of the base plate portion forms the air diffuser portion, and the edge of the second air diffuser plate is limited by the limiting sidewall portion. By providing a limiting sidewall portion at the edge of the first air diffuser plate, the second air diffuser plate can be laterally limited, which not only improves the stability of the air diffuser assembly but also prevents lateral movement between the second and first air diffuser plates during air conditioner operation. This avoids changes in the positional correspondence between the air diffuser holes on the first and second air diffuser plates, thus preventing any impact on the air diffuser assembly's air diffusion effect.

[0006] In an optional technical solution, the free end of the limiting sidewall is provided with a limiting protrusion, and a limiting space is formed between the limiting protrusion and the base plate; the sidewall of the second air diffuser is provided with a positioning protrusion, which is inserted into the limiting space and limited by the limiting protrusion and the base plate. By providing the limiting protrusion to form a limiting space, which cooperates with the positioning protrusion of the second air diffuser, the relative position of the second air diffuser relative to the first air diffuser in the thickness direction of the air diffuser assembly is limited.

[0007] In an optional technical solution, the limiting sidewall portion includes a limiting latch, and the sidewall of the second air diffuser plate is provided with a limiting protrusion. The limiting latch engages with the limiting protrusion, and the limiting latch and the base plate portion are respectively located on both sides of the limiting protrusion. By providing the limiting latch, the limiting latch can engage with the limiting protrusion to prevent the second air diffuser plate from detaching from the first air diffuser plate along the thickness direction of the first air diffuser plate. It can even apply pressure to the second air diffuser plate, pressing it against the first air diffuser plate, and, in conjunction with the limiting sidewall portion, laterally limit the second air diffuser plate, thus fixing the second air diffuser plate to the first air diffuser plate.

[0008] In an optional technical solution, the substrate portion is provided with a first magnetic attraction portion, and the second air diffuser plate is provided with a second magnetic attraction portion. The first magnetic attraction portion and the second magnetic attraction portion are disposed opposite to each other and are attracted together. By providing the first magnetic attraction portion and the second magnetic attraction portion on the substrate portion and the second air diffuser plate respectively, the first air diffuser plate and the second air diffuser plate can be fixed by utilizing the mutual attraction of the first magnetic attraction portion and the second magnetic attraction portion.

[0009] In an optional technical solution, the air diffuser includes a grid section, which comprises multiple grid meshes. Each grid mesh includes planar rods and planar air diffuser holes, the planar air diffuser holes being enclosed by the planar rods of each grid mesh. The grid section also includes three-dimensional diagonal rods extending from the edge of the grid mesh. Multiple three-dimensional diagonal rods extending from the edge of the same grid mesh intersect, and the three-dimensional diagonal rods and the planar rods intersect to form three-dimensional air diffuser holes. In each air diffuser plate, the three-dimensional diagonal rods extend to the same side in the thickness direction of the grid section. By configuring the air diffuser as a combination of a grid mesh section and three-dimensional diagonal rods, the airflow can be diffused once using the grid mesh section, and also once using the three-dimensional air diffuser holes formed by the three-dimensional diagonal rods extending from the edge of the same grid mesh. This allows the airflow to be dispersed twice by the planar air diffuser holes and the three-dimensional air diffuser holes when passing through the same air diffuser plate, thereby improving the airflow effect. Moreover, since the three-dimensional air diffuser is inclined relative to the grid mesh, the actual ventilation area of ​​the three-dimensional air diffuser is larger than the area of ​​the three-dimensional air diffuser projected onto the grid mesh along the thickness direction of the air diffuser plate. The total area of ​​multiple three-dimensional air diffusers may still be larger than the area of ​​the planar air diffusers, and the ventilation area will not be reduced, thus ensuring a large airflow in the air diffuser section.

[0010] In an optional technical solution, multiple three-dimensional diagonal braces extending from the edge of the same grid intersect at the same vertex. This arrangement allows the three-dimensional diagonal braces to support each other, increasing their rigidity. Furthermore, it eliminates the possibility of small-section holes that might form when multiple three-dimensional diagonal braces intersect at multiple points; these small-section holes, although through-holes, are essentially unable to provide ventilation. Therefore, this solution can increase the cross-sectional area of ​​each three-dimensional air diffuser formed by the three-dimensional diagonal braces and the planar braces.

[0011] In an optional technical solution, multiple three-dimensional diagonal members extending from the edge of the same grid mesh and the grid mesh together form a regular polygonal pyramid. This arrangement maximizes and maintains the consistency of the area of ​​each three-dimensional air diffuser hole, resulting in a more uniform airflow distribution effect. Furthermore, because the three-dimensional diagonal members are the edges of a regular polygonal pyramid, the stress on each three-dimensional diagonal member is consistent, preventing uneven stress on some members and uneven stress on others, which could lead to inconsistent deformation or premature damage to some members due to uneven load distribution.

[0012] In an optional technical solution, the three-dimensional inclined rods on two adjacent diffuser plates in each group extend towards another diffuser plate, and the intersecting apexes of the multiple three-dimensional inclined rods on each diffuser plate are correspondingly arranged and configured to abut against each other. This arrangement allows one diffuser plate to bear the airflow load on the other. Generally, since the velocity of the airflow within the diffuser assembly decreases overall, under the same conditions, the lower the airflow velocity, the smaller the force exerted on the diffuser plate. The diffuser plate on the upstream side of the airflow experiences a larger airflow force, while the diffuser plate on the downstream side experiences a smaller force. Therefore, when the apexes of the two diffuser plates abut against each other, the downstream diffuser plate can partially bear the load of the upstream diffuser plate.

[0013] In an optional technical solution, the number of three-dimensional diagonal rods connected to each of the grid meshes is m < n, and m ≥ 2, where n is the number of sides of the grid mesh. In two adjacent air diffusers, the projection of the three-dimensional diagonal rod of each air diffuser along the thickness direction of the air diffuser assembly is located within the three-dimensional air diffuser hole of the other air diffuser. This arrangement of the three-dimensional diagonal rods ensures that after the airflow passes through the three-dimensional air diffuser hole on one air diffuser, it is dispersed by the three-dimensional diagonal rod on the other air diffuser, thereby reducing the airflow velocity and achieving multiple dispersion of the outlet airflow. Furthermore, it reduces material usage and lowers production costs.

[0014] In an optional technical solution, the grid mesh portion and the three-dimensional inclined bar portion on two adjacent air diffuser plates in each group are mirror-symmetrical. This arrangement allows for greater uniformity in the molds used to manufacture the air diffuser plates, which helps reduce manufacturing costs.

[0015] In an optional technical solution, the air diffuser is formed by connecting a Class A recess and a Class B recess. The Class A recess is recessed from the first surface of the air diffuser, and the Class B recess is recessed from the second surface of the air diffuser. The first surface and the second surface are surfaces opposite in the thickness direction of the air diffuser. One Class A recess connects to multiple Class B recesses to form multiple air diffusers, and / or one Class B recess connects to multiple Class A recesses to form multiple air diffusers. Taking the first surface as the windward side of the air diffuser and the second surface as the air outlet side of the air diffuser as an example, when the airflow enters the Class A recess, which serves as the air inlet chamber, it first contracts, then disperses and enters multiple air diffusers. When the airflow flows out of the air diffuser and enters the Class B recesses connected to each air diffuser, it can expand again. The airflow entering each Class B recess enters through the air diffusers connecting different Class A recesses, and the Class B recesses also have the function of secondary mixing of converging and dispersing. As airflow passes through the diffuser, it is not only dispersed by the diffuser but also undergoes multiple stages of contraction, dispersion, diffusion, and mixing, significantly improving the airflow dispersion effect. Moreover, this design allows for the creation of a recessed area on the surface of the diffuser, forming multiple airflow holes. This increases the number of airflow holes, thereby improving the density of airflow holes per unit area and maintaining effective airflow.

[0016] In an optional technical solution, adjacent diffusers have two opposing surfaces, with the recesses on one surface offset from the recesses on the other surface. This arrangement ensures that the cross-sectional area of ​​the passageway formed between the two recesses on the opposing surfaces is smaller than the opening of the recess. This cross-sectional area allows for further throttling of the airflow and also facilitates airflow dispersion.

[0017] In an optional technical solution, adjacent air diffusers have two opposing surfaces, and a protrusion between multiple recesses on one surface corresponds to a recess on the other surface. With this configuration, after the airflow passes through the diffuser holes of one diffuser and converges in the recess, it can be further dispersed by the protrusion of another diffuser. This allows for more frequent dispersion of the airflow within the limited thickness of the diffuser assembly, resulting in a better zero-wind-feel effect.

[0018] In an optional technical solution, on a pair of same-side surfaces of adjacent air diffusers, a plurality of recesses on one side are correspondingly arranged with a plurality of recesses on the other side; on another pair of same-side surfaces of adjacent air diffusers, a plurality of recesses on one side are staggered with a plurality of recesses on the other side. This arrangement allows airflow exiting from one diffuser hole facing the recess of another air diffuser to exit from at least two diffuser holes on the other air diffuser. Furthermore, the airflow flowing through the diffuser holes on the other air diffuser is not just from a single diffuser hole, but from multiple diffuser holes. Therefore, during the airflow splitting and merging process, the airflow velocity can be effectively consumed, thereby achieving a zero-wind-feel function.

[0019] The second objective of this utility model is to provide an air conditioner that solves the technical problem of the difficulty in manufacturing air-dissipating components with good air-dissipating effect.

[0020] The air conditioner provided in the second aspect of this utility model includes an indoor unit and an outdoor unit. The air outlet of the indoor unit is provided with any of the above-mentioned air dissipation components. The indoor unit and the outdoor unit are connected by a refrigerant connection pipe.

[0021] By incorporating the aforementioned air venting components into the air conditioner, the air conditioner gains all the advantages of these components, which will not be elaborated upon here.

[0022] The third aspect of this utility model aims to provide an air conditioner that solves the technical problem of the difficulty in manufacturing air-dissipating components with good air-dissipating effect.

[0023] The air conditioner provided in the third aspect of this utility model includes an indoor unit and an outdoor unit. The indoor unit is equipped with a diffuser assembly as described above at its air outlet. The indoor and outdoor units are connected via a refrigerant connection pipe. When the air conditioner is in zero-wind mode, the first diffuser is located on the leeward side of the second diffuser. With this configuration, the direction of the airflow is such that the second diffuser is closer to the first diffuser, and the overall velocity of the airflow within the diffuser assembly decreases. The airflow force on the second diffuser is greater than that on the first diffuser. In other words, the force exerted by the airflow on each diffuser is such that the force on the second diffuser closer to the first diffuser is greater than the force on the first diffuser farther from the second diffuser. If the diffuser assembly is fixedly installed in the main body of the indoor unit, fixing the first diffuser allows for the fixing of the second diffuser. If the air diffuser assembly is rotatably installed inside the air conditioner body, the rotating shaft of the air diffuser assembly can be set on the second air diffuser plate to avoid interfering with the connection between the first and second air diffuser plates if it is set on the first air diffuser plate.

Detailed Implementation

[0052] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0053] This application uses a wall-mounted air conditioner indoor unit as an example, but this does not preclude the application of the product to a cabinet-type air conditioner indoor unit. Unless otherwise specified, the definitions of direction in this application are as follows: "Front" refers to the side of the wall-mounted air conditioner indoor unit facing the main indoor space, while "rear" refers to the side facing the wall on which it is mounted. "Below" refers to the side of the wall-mounted air conditioner indoor unit facing the ground. "Above" refers to the side of the wall-mounted air conditioner indoor unit facing the ceiling. "Left" and "right" can be defined based on the aforementioned front, rear, and below; that is, when an observer faces the wall where the wall-mounted air conditioner indoor unit is installed, the observer's left hand is the left side, and the observer's right hand is the right side. Furthermore, "inner" and "outer" are defined based on the shape of a cavity, box, or cylinder; the side of the cavity, box, or cylinder facing its internal space is the inner side, and the outer side is the side of the cavity or box facing its external space.

[0054] Example 1: Figure 1 This is a schematic diagram of the air diffuser assembly provided in Example 1. Figure 2 This is a schematic diagram of the air diffuser assembly provided in Embodiment 1, viewed from another direction. Figure 3 This is a three-dimensional disassembled view of the air dissipation component provided in Embodiment 1. Figure 4 This is a three-dimensional disassembled view of the air diffuser assembly provided in Embodiment 1. Figures 1-4 As shown, the air dispersing assembly provided in Embodiment 1 includes multiple relatively fixed and stacked air dispersing plates. Each air dispersing plate includes an air dispersing part 130. Along the thickness direction of the air dispersing assembly, the air dispersing part 130 of each air dispersing plate is at least partially correspondingly arranged. The air dispersing part 130 is distributed with multiple air dispersing holes 300. The solid structure of the air dispersing part 130 has only one layer of material in the thickness direction of the air dispersing plate.

[0055] By setting the air diffuser assembly to include multiple relatively fixed air diffuser plates, and ensuring that the air diffuser portion 130 on each air diffuser plate has only one layer of material in the thickness direction, the relatively simple shape of the air diffuser plate can be processed by injection molding. Then, multiple single air diffuser plates are stacked and fixed to form a stacked air diffuser assembly, thus eliminating the need for 3D printing to process the overall air diffuser assembly. This significantly reduces the manufacturing difficulty and cost of the air diffuser assembly, shortens the processing time, and improves production efficiency.

[0056] It should be noted that in this application, the multiple air diffuser panels are relatively fixed, which does not mean that the multiple air diffuser panels must be disassembled in a destructive manner. It simply means that each air diffuser panel is relatively fixed when the air conditioner is operating normally. In fact, the air diffuser panels can be detachably connected.

[0057] In this embodiment, the air diffuser assembly is located at the air outlet of the indoor unit of the wall-mounted air conditioner. When the air diffuser assembly functions, the airflow from the air conditioner passes through the air diffuser assembly from one side and enters the room from the other side. The overall direction of the airflow passing through the air diffuser assembly is roughly the same as the thickness direction of the air diffuser assembly. Because the air diffuser assembly has air diffuser holes 300, the diameter of which is small, typically only a few millimeters or less, the airflow speed is significantly reduced after passing through the air diffuser holes 300. This achieves the goal of the air conditioner supplying cool air to the room without the user being directly exposed to cold air, commonly known as zero-wind-feel.

[0058] like Figures 1-4 As shown, optionally, the air diffuser assembly includes a first air diffuser plate 100 and a second air diffuser plate 200. The first air diffuser plate 100 includes a base plate portion 120 and a limiting sidewall portion 110 disposed on the edge of the base plate portion 120. At least a portion of the base plate portion 120 forms an air diffuser portion 130. The edge of the second air diffuser plate 200 is limited by the limiting sidewall portion 110. By providing the limiting sidewall portion 110 on the edge of the first air diffuser plate 100, the second air diffuser plate 200 can be laterally limited, which not only improves the stability of the air diffuser assembly, but also prevents lateral movement between the second air diffuser plate 200 and the first air diffuser plate 100 during the operation of the air conditioner, so as to prevent the positional correspondence of the air diffuser holes 300 on the first air diffuser plate 100 and the second air diffuser plate 200 from changing and affecting the air diffuser effect of the air diffuser assembly.

[0059] Specifically, in this embodiment, the first air diffuser 100 is generally rectangular, and the second air diffuser 200 is also generally rectangular. The lateral dimension of the first air diffuser 100 is larger than that of the second air diffuser 200. The lateral dimension refers to the dimension in a direction parallel to the surfaces of the first and second air diffusers 100 and 200. Lateral movement is movement perpendicular to the thickness direction of the air diffuser assembly, specifically the movement of either the first air diffuser 100 or the second air diffuser 200 relative to the other on the plane where they contact. In this embodiment, the limiting sidewall portion 110 protrudes from the edge of the base plate portion 120 along the thickness direction of the base plate portion 120. The limiting sidewall portion 110 can extend continuously along the length direction of the corresponding edge. Of course, in other implementations, the limiting sidewall portion 110 may not extend continuously along the length direction of the edge; for example, it may be discontinuously provided.

[0060] In this application, terms such as "up," "down," "left," "right," "front," and "back" that directly describe direction and orientation, when used to describe the composition of the air diffuser assembly, are based on the horizontal placement of the first air diffuser plate 100 and the second air diffuser plate 200, and are illustrated by the example of the first air diffuser plate 100 being located above the second air diffuser plate 200.

[0061] like Figures 3-4 As shown, optionally, the substrate portion 120 is provided with a first magnetic attraction portion 140, and the second air diffuser plate 200 is provided with a second magnetic attraction portion 210. The first magnetic attraction portion 140 and the second magnetic attraction portion 210 are disposed opposite to each other and are attracted together. By providing the first magnetic attraction portion 140 and the second magnetic attraction portion 210 on the substrate portion 120 and the second air diffuser plate 200 respectively, the first air diffuser plate 100 and the second air diffuser plate 200 can be fixed by utilizing the mutual attraction of the first magnetic attraction portion 140 and the second magnetic attraction portion 210.

[0062] In this embodiment, the first magnetic attraction part 140 and the second magnetic attraction part 210 can be magnets or a combination of magnets and ferromagnetic materials, respectively. For example, the magnetic poles of the first magnetic attraction part 140 and the second magnetic attraction part 210 have the same direction of arrangement. Specifically, the lower end of the first magnetic attraction part 140 is the S pole, and the upper end is the N pole, while the upper end of the second magnetic attraction part 210 is the N pole and the lower end is the S pole. When the second air diffuser plate 200 is installed on the first air diffuser plate 100, the N pole at the upper end of the first magnetic attraction part 140 and the S pole at the lower end of the second magnetic attraction part 210 attract each other to fix the first magnetic attraction part 140 and the second magnetic attraction part 210. Of course, one of the first magnetic attraction part 140 and the second magnetic attraction part 210 can be a magnet, and the other can be an iron sheet or an iron pillar. The first magnetic attraction part 140 is fixed to the substrate part 120, and the second magnetic attraction part 210 is fixed to the second air diffuser plate 200.

[0063] In this embodiment, the first air diffuser plate 100 and the second air diffuser plate 200 are fixed by magnetic attraction. The first magnetic attraction part 140 and the second magnetic attraction part 210 can be respectively disposed at their edges, or they can also be disposed at their middle, thus fixing them at their middle as well. Furthermore, in the magnetic attraction fixing scheme, limiting sidewalls 110 are provided at all four edges of the roughly rectangular base plate portion 120 to laterally limit the second air diffuser plate 200.

Figure 8 This is a schematic diagram of the cell structure of the air diffuser section in the air diffuser assembly provided in Embodiment 1; Figure 9 This is a schematic diagram of the structure of the unit cell of the air diffuser in the air diffuser assembly provided in Embodiment 1, viewed from another direction; as shown. Figures 5-9As shown, optionally, the ventilation holes are formed by connecting a Class A recess and a Class B recess. The Class A recess is recessed from the first surface of the ventilation vent 130, and the Class B recess is recessed from the second surface of the ventilation vent 130. The first surface and the second surface are surfaces opposite to each other in the thickness direction of the ventilation vent 130. One Class A recess connects to multiple Class B recesses to form multiple ventilation holes 300, and / or one Class B recess connects to multiple Class A recesses to form multiple ventilation holes 300. Taking the first surface as the windward side of the diffuser and the second surface as the air outlet side of the diffuser as an example, when the airflow enters the Class A recess, which serves as the air inlet chamber, it first contracts, then disperses and enters multiple diffuser holes 300. Upon exiting from the diffuser holes 300 and entering the Class B recesses connected to each diffuser hole 300, it can expand again. The airflow entering each Class B recess enters through the diffuser holes 300 connecting different Class A recesses. The Class B recesses also have a secondary mixing effect of converging and dispersing. The airflow passing through the diffuser is not only dispersed by the diffuser but also undergoes multiple stages of contraction, dispersion, diffusion, and mixing, significantly improving the airflow dispersion effect. Moreover, this design allows for the formation of multiple diffuser holes 300 by machining a single recess on the surface of the diffuser, increasing the number of diffuser holes 300 and thus improving the density of diffuser holes 300 per unit area of ​​the diffuser, maintaining effective airflow.

[0065] Furthermore, this arrangement ensures that a recess 400 on one surface corresponds to a plurality of adjacent recesses 400 on another surface—and a protrusion 500 between the recesses 400 that form the air diffuser holes 300. On one hand, the solid portion of the protrusion 500 can accommodate the recess 400, reducing the overall thickness of the air diffuser plate, decreasing the overall material usage, and lowering the cost of the air diffuser assembly. On the other hand, because the recesses 400 that connect to form the air diffuser holes 300 are arranged in this way, most of the remaining solid material forms an edge with a large acute angle to the surface of the air diffuser 130, which helps to ensure the rigidity and strength of the air diffuser 130 with a smaller material usage.

[0066] Specifically, in this embodiment, the recessed portion 400 can be approximately hemispherical, or the shape of the recess can be a local sphere with a depth less than the height of the hemispherical shape. Of course, in another implementation, it can also be half of an ellipsoid, regardless of whether the surface of the air diffuser portion 130 is perpendicular to the major or minor axis of the ellipsoid.

[0067] Specifically, in this embodiment, in addition to the recesses 400 located at the edge of each surface of the air diffuser 130, six recesses 400 are evenly distributed around each recess 400, that is, three adjacent recesses 400 form an equilateral triangle. In other words, the angle between the line connecting the multiple adjacent recesses 400 of a recess 400 and the recess 400 is 60°. Of course, the recesses 400 located at the edge also have two adjacent recesses 400 in the length direction of the edge, and in a row or column of recesses 400 adjacent to the recess 400, the angle between the line connecting the two nearest recesses 400 and the recess 400 is 60°, and the angle between these two recesses 400 and the length direction of the edge is also 60°. Of course, in another implementation, the recesses 400 on each surface of the air diffuser 130 can also be arranged in a rectangular array.

[0068] In this embodiment, disregarding the recesses 400 located at the edges, in each diffuser plate, a recess 400 on one surface corresponds to a protrusion 500 between three adjacent recesses 400 on another surface. That is, the three adjacent recesses 400 on the other surface are arranged in an equilateral triangle; specifically, the projection of a recess 400 on one surface along the thickness direction of the diffuser plate is located at the center of the equilateral triangle formed by the three adjacent recesses 400 on the other surface, or corresponds to the protrusion 500 in the middle of the three adjacent recesses 400 on the other surface. In other words, each recess 400 can form three diffuser holes 300 with the three recesses 400 on the other surface. In this embodiment, all recesses 400 are the same size and shape. Therefore, the three diffuser holes 300 formed between one recess 400 and the three recesses 400 on the other side are also arranged in an equilateral triangle, and the plane of this equilateral triangle is perpendicular to the thickness direction of the diffuser plate.

[0069] Specifically, you can refer to Figure 7 and Figure 8 Without considering the recesses 400 at the edge positions, one-third of a recess 400 on one side of the three ventilation holes 300 and three recesses 400 on the back side, along with the corresponding protrusions 500, can form a structure similar to a unit cell in chemistry. Each unit cell occupies a regular hexagonal prism space. The ventilation section 130 can include a plurality of such unit cells, and these unit cells on each ventilation section 130 are arranged closely in a honeycomb structure in the plane. Of course, in another implementation, the recesses 400 on each surface of the ventilation section 130 can also be arranged in a rectangular array. For the recesses 400 at non-edge positions, the recesses 400 on one side surface correspond to the center of four adjacent recesses 400 on the other side surface.

[0070] Figure 10 for Figure 3 Enlarged views of parts A and B. Figure 11 for Figure 4 Enlarged views of parts C and D. Figure 12 This is a schematic diagram showing the correspondence between the air diffuser holes and the recessed portion in the air diffuser assembly provided in Embodiment 1. Figures 10-12 As shown, optionally, adjacent diffusers have two opposing surfaces, with the recesses 400 on one surface offset from the recesses 400 on the other surface. This arrangement ensures that the cross-sectional area of ​​the passageway formed between the two recesses 400 on the opposing surfaces is smaller than the opening of the recess 400. This cross-sectional area allows for further throttling of the airflow and also facilitates airflow dispersion.

[0071] like Figures 10-12 As shown, optionally, adjacent diffusers have two opposing surfaces, with a protrusion 500 between multiple recesses 400 on one surface corresponding to a recess 400 on the other surface. With this configuration, after the airflow passes through the diffuser holes 300 of one diffuser and converges in the recess 400, it can be further dispersed by the protrusion 500 of another diffuser. This allows for more frequent dispersion of the airflow within the limited thickness of the diffuser assembly, resulting in a better zero-wind-feel effect.

[0072] Specifically, with Figure 3 For example, Figure 3 The right half is the second diffuser plate 200, and the left half is the first diffuser plate 100. The second diffuser plate 200 has two bottom recesses 400 in the first column from the left, and a second recess 400 in the second column from the left. On the second diffuser plate 200, there is a recess 400 on the opposite side of the protrusion 500 between these three recesses 400. The recess 400 and the three recesses 400 form a diffuser hole 300. This recess 400 corresponds to a protrusion 500 on the first diffuser plate 100. This protrusion 500 is located between the two bottom recesses 400 in the left column of the first diffuser plate 100 and the second recess 400 in the second column from the left, roughly forming a quasi-triangular shape with curved edges. Therefore, the airflow passing through the recessed portion 400 will be dispersed by the protrusion 500, which is shaped like a quasi-triangular shape, and will be diverted to each recessed portion 400 adjacent to the protrusion 500, and discharged through each air diffuser 300 of each recessed portion 400.

[0073] like Figures 10-12As shown, optionally, on a pair of same-side surfaces of adjacent diffusers, a plurality of recesses 400 on one side are correspondingly arranged with a plurality of recesses 400 on the other side; on another pair of same-side surfaces of adjacent diffusers, a plurality of recesses 400 on one side are staggered with a plurality of recesses 400 on the other side. This arrangement allows airflow exiting from one diffuser hole 300 facing the recesses 400 of another diffuser to exit from at least two diffuser holes 300 of the other diffuser. Furthermore, the airflow flowing through the diffuser holes 300 on the other diffuser is not just airflow entering from one diffuser hole 300, but rather airflow converging from multiple diffuser holes 300. Therefore, during the splitting and merging of airflow, the airflow velocity can be effectively consumed, thereby achieving a zero-wind-feel function.

[0074] Specifically, the following is based on Figure 12 For clarity, the circles in the diagram are divided into two sizes. The larger circle represents the opening edge of the recess 400 on the second diffuser plate 200, while the smaller circle represents the opening edge of the recess 400 on the first diffuser plate 100. Although the circles drawn in the diagram vary in size, the opening edges of the recesses 400 on each diffuser plate can actually be the same size; they are drawn with different diameters for ease of distinction. Specifically, the light blue circle represents the opening edge of the recess 400 on the surface of the second diffuser plate 200 facing the first diffuser plate 100, while the red circle represents the opening edge of the second diffuser plate 200 facing away from the first diffuser plate 100. The dark blue circle represents the opening edge of the recess 400 on the surface of the first diffuser plate 100 facing the second diffuser plate 200, while the green circle represents the opening edge of the first diffuser plate 100 facing away from the second diffuser plate 200. Since this diagram is only intended to show the airflow direction between the various three-sealed holes, the air diffuser 300 has been simplified and represented only by an ellipse, without showing the wall thickness of the air diffuser 300. Specifically, the dashed ellipse represents the air diffuser 300 located on the second air diffuser plate 200, while the solid ellipse represents the air diffuser 300 located on the first air diffuser plate 100.

[0075] exist Figure 10In the diagram, the second air diffuser 200 has two recessed portions 400 at the bottom of the first column of illustrations from the left—the first recessed portion 401 and the second recessed portion 402; the second recessed portion 400 from the bottom of the second column of illustrations from the left—the third recessed portion 403; and a fourth recessed portion 404 on the opposite side of the protrusion 500 between these three recessed portions 400. The fourth recessed portion 404 and the three recessed portions 400 form air diffusers 300—the first air diffuser 301, the second air diffuser 302, and the third air diffuser 303. The first air diffuser 301 is formed by the first recessed portion 401 and the fourth recessed portion 404; the second air diffuser 302 is formed by the second recessed portion 402 and the fourth recessed portion 404; and the third air diffuser 303 is formed by the third recessed portion 403 and the fourth recessed portion 404. The fourth recess 404 corresponds to a protrusion 500 on the first air diffuser 100, which is the first protrusion 501. The first protrusion 501 is located between the two bottommost recesses 400 on the left side of the first air diffuser 100 diagram—the fifth recess 405 and the sixth recess 406—and between the second recess 400 from bottom to top in the second column of the diagram from the left—the seventh recess 407. However, there is no recess 400 corresponding to the first protrusion 501 on the other side of the first air diffuser 100. A second protrusion 502 is provided on the upper surface of the first air diffuser 100. The second protrusion 502 and the first protrusion 501 are arranged along the length direction of the first air diffuser 100. The second protrusion 502 is formed by a sixth recess 406, a seventh recess 407, and an eighth recess 408. The eighth recess 408 is the third recess 400 from bottom to top in the second column from the left in the diagram of the first air diffuser 100. The ninth recess 409 corresponds to the second protrusion 502. In addition, the bottommost recess 400 in the second column from the left in the diagram of the upper surface of the first air diffuser 100 is the tenth recess 410. The protrusion 500 between the tenth recess 410, the fifth recess 405, and the seventh recess 407 is the third protrusion 503. The eleventh recess 411 corresponds to the third protrusion 503 on the lower surface of the first air diffuser 100. A fourth ventilation hole 304 is formed between the eleventh recess 411 and the fifth recess 405, and a fifth ventilation hole 305 is formed between the eleventh recess 411 and the seventh recess 407. A sixth ventilation hole 306 is formed between the ninth recess 409 and the sixth recess 406, and a seventh ventilation hole 307 is formed between the ninth recess 409 and the seventh recess 407. And as... Figure 11 As shown in the diagram, the second recess 400 above the first column from the left in the first air diffuser plate 100 is the twelfth recess 412. An eighth air diffuser hole 308 is formed between the twelfth recess 412 and the fifth recess 405, and a ninth air diffuser hole 309 is formed between the twelfth recess 412 and the sixth recess 406.

[0076] exist Figure 12 As can be seen, the airflow discharged from the first diffuser hole 301 can enter the eighth diffuser hole 308 and the fourth diffuser hole 304; the airflow discharged from the second diffuser hole 302 can enter the sixth diffuser hole 306 and the ninth diffuser hole 309; and the airflow discharged from the third diffuser hole 303 can enter the fifth diffuser hole 305 and the seventh diffuser hole 307. Of course, the airflow discharged from the first diffuser hole 301 does not absolutely enter only the eighth diffuser hole 308 and the fourth diffuser hole 304. Since the eighth diffuser hole 308 and the fourth diffuser hole 304 are relatively close to the first diffuser hole 301 and the distance is basically the same, and the shape of the object flowing through them is also the same, so it mainly enters these two diffuser holes 300. Of course, a small part may also flow through the thirteenth diffuser hole 313 in the fifth recess 405. The thirteenth air diffuser 313 is formed by the fifth recess 405 and the thirteenth recess 413, and the thirteenth recess 413 is part of the first air diffuser plate 100. Figure 11 The first recess 400 above the first column from the left is shown; the airflow discharged from the second air diffuser 302 and the third air diffuser 303 is similar and will not be described in detail.

[0077] The airflow flowing into the fourth diffuser hole 304 includes the airflow flowing out of the first diffuser hole 301 and the tenth diffuser hole 310, wherein the tenth diffuser hole 310 is formed by the first recess 401 and the fourteenth recess 414, and the fourteenth recess 414 is part of the second diffuser plate 200. Figure 11 The topmost recess 400 in the first column from the left is shown. The airflow flowing into the fifth diffuser 305 includes the airflow flowing out of the third diffuser 303 and the twelfth diffuser 312. The twelfth diffuser 312 is formed by the third recess 403 and the fifteenth recess 415. The fifteenth recess 415 is part of the second diffuser plate 200. Figure 11 The second column from the left shows the top recess 400. The airflow flowing into the sixth diffuser 306 includes the airflow exiting from the second diffuser 302 and the eleventh diffuser 311. The eleventh diffuser 311 is formed by the second recess 402 and the sixteenth recess 416. The sixteenth recess 416 is part of the second diffuser plate 200. Figure 11The third recess 400 from the top of the first column from the left is shown. Of course, taking the fifth diffuser 305 as an example, the airflow entering the fifth diffuser 305 is not absolutely limited to the airflow from the third diffuser 303 and the twelfth diffuser 312. It's just that the third and twelfth diffusers 303 and 312 are relatively close to the fifth diffuser 305 and the objects they pass through are also similar in shape. Therefore, it is mainly the airflow from these two diffusers 300 that enters the fifth diffuser 305. Of course, a small portion of the airflow may also exit from the fourteenth diffuser 314, which is formed by the third recess 403 and the seventeenth recess 417. The seventeenth recess 417 is part of the second diffuser plate 200. Figure 11 The second indentation from the top of the second column from the left is shown as 400.

[0078] Therefore, the airflow exiting from one of the airflow holes 300 of the second air diffuser 200 can flow through at least two airflow holes 300 of the first air diffuser 100. And the airflow flowing into the airflow holes 300 of the first air diffuser 100 can include at least the airflow exiting from at least two airflow holes 300 on the second air diffuser 200.

[0079] Of course, in another implementation, the air-diffusing portion 130 of the first air-diffusing plate 100 can be configured to correspond completely with the air-diffusing portion 130 of the second air-diffusing plate 200. That is, the recessed portion 400 on the windward side of the first air-diffusing plate 100 corresponds to the recessed portion 400 on the windward side of the second air-diffusing plate 200, and the recessed portion 400 on the leeward side of the first air-diffusing portion 130 corresponds to the recessed portion 400 on the leeward side of the second air-diffusing plate 200. This situation is as follows: Figure 13 As shown, in the partial cross-section, the distribution of the air vents 300, the recessed portion 400, and the protruding portion 500 of the two air vents is exactly the same.

[0080] Furthermore, a separation through hole can be provided in the recessed portion 400 of the first air diffuser 100 corresponding to the partial protrusion 500, extending along the thickness direction of the first air diffuser 100, so that when the first air diffuser 100 and the second air diffuser 200 are separated, a rod-shaped tool can be inserted into the separation through hole to overcome the attraction of the first magnetic attraction portion 140 and the second magnetic attraction portion 210 and push the second air diffuser 200 out of the first air diffuser 100.

[0081] Additionally, the second air diffuser 200 can be positioned on the windward side of the first air diffuser 100. A rotating shaft 220 can be mounted on the second air diffuser 200 to allow the air diffuser assembly to rotate relative to the air conditioning unit, driven by a corresponding drive component. The rotating shaft 220 can directly mount the driven component or a drive structure of a transmission device connected to the drive component; for example, it can have gears mounted on the rotating shaft 220. Alternatively, the rotating shaft 220 can simply serve a pivotal positioning function, with the drive component separately connected to a transmission structure such as a linkage mechanism to move the air diffuser assembly.

[0082] Example 2: Figure 14 This is a schematic diagram of the air diffuser assembly provided in Embodiment 2. Figure 15 This is a three-dimensional disassembled view of the air diffuser assembly provided in Embodiment 2. This embodiment is largely the same as Embodiment 1, with the main difference being the connection method between the first air diffuser plate 100 and the second air diffuser plate 200: as shown... Figure 14 and Figure 15 As shown, the free end of the limiting sidewall portion 110 is provided with a limiting protrusion 160, and a limiting space is formed between the limiting protrusion 160 and the base plate portion 120; the sidewall of the second air diffuser 200 is provided with a positioning protrusion 250, which is inserted into the limiting space and limited by the limiting protrusion 160 and the base plate portion 120. By providing the positioning protrusion 250 to form a limiting space, and cooperating with the positioning protrusion 250 of the second air diffuser 200, the relative position of the second air diffuser 200 with respect to the first air diffuser 100 in the thickness direction of the air diffuser assembly is limited.

[0083] Specifically, in this embodiment, limiting sidewall portions 110 are provided on two long sides and one short side of the rectangular first air diffuser 100. Limiting protrusions 160 are provided at the free ends of the limiting sidewall portions 110 on the two upper sides, while the limiting sidewall portions 110 on the short side do not have limiting protrusions 160. In this way, the two opposing limiting spaces can form a sliding groove for the second air diffuser 200 to slide. Even if there is no limiting on the other short side of the rectangle, in actual use, whether the air diffuser assembly functions as a movable guide plate to open or close the air outlet of the wall-mounted air conditioner indoor unit, or is fixedly installed at the air outlet of the wall-mounted air conditioner indoor unit, the short side of the rectangle will not face downwards. Even if no structure is provided on the short side to prevent the second air diffuser 200 from sliding out, the second air diffuser 200 will not slide out.

[0084] If the first air diffuser plate 100 and the second air diffuser plate 200 are placed horizontally, with the first air diffuser plate 100 above the second air diffuser plate 200, a limiting protrusion 160 is provided at the upper end of the limiting sidewall portion 110. The limiting protrusion 160 can extend continuously along the length direction of the first air diffuser plate 100. Of course, the limiting protrusion 160 can also be arranged intermittently. Although the intermittent arrangement of the limiting sidewall portion 110 and the limiting protrusion 160 can save materials, considering that there will be a gap between the first air diffuser plate 100 and the second air diffuser plate 200 when they slide relative to each other, the relative angle between them cannot be strictly and precisely determined. If the relative angle deviates, the end face of the first air diffuser plate 100 may abut against the solid part next to the disconnected part of the limiting sidewall portion 110, which would require adjustment of the direction to continue insertion.

[0085] It should be noted that in this application, the air diffuser portion 130 of the air diffuser plate is limited to having only one layer of material in the thickness direction, not that the first air diffuser plate 100 and the second air diffuser plate 200 have only one layer of material in the thickness direction at each position. Even with only one layer of material, the air diffuser portion 130, due to its numerous detailed structures, can still be injection molded. Furthermore, although the area where the limiting protrusion 160 is located has two layers of material, the groove space between the limiting protrusion 160 and the substrate portion 120 can still be injection molded using a slider, with the limiting protrusion 160 being provided on the limiting sidewall.

[0086] Specifically, the limiting protrusion 160 is located near the base plate portion 120 on the side wall of the second air diffuser 200, thereby reducing the height of the limiting side wall portion 110 and reducing material consumption.

[0087] Furthermore, in this embodiment, a limiting insert 170 is also provided. After the limiting protrusion 160 of the second air diffuser 200 is inserted into the limiting space and moves into place, the convex-shaped limiting insert 170 can be inserted into the limiting space with its thickness direction parallel to the length direction of the first air diffuser 100. Since the two ends of the limiting insert 170 have friction with the side wall of the limiting space, the limiting insert 170 can be engaged with the end of the first air diffuser 100. Therefore, the resistance to the second air diffuser 200 disengaging from the first air diffuser 100 can be increased, which is beneficial for fixing the second air diffuser 200 to the first air diffuser 100.

[0088] Of course, since the tendency of the second air diffuser 200 to detach from the first air diffuser 100 along the thickness direction is blocked by the limiting protrusion 160, it is not necessary to provide a through hole in the first air diffuser 100 for the operator to detach the second air diffuser 200 from the first air diffuser 100 along the thickness direction. Similarly, it is not necessary to provide the first magnetic part 140 and the second magnetic part 210 to attract each other for fixation.

[0089] Example 3: Figure 16 This is a schematic diagram of the air diffuser assembly provided in Embodiment 3. Figure 17 This is a schematic diagram of the air diffuser assembly provided in Embodiment 3, viewed from another direction. Figure 18 This is a three-dimensional disassembled view of the air diffuser assembly provided in Embodiment 3. Figure 19 This is a three-dimensional disassembled view of the air diffuser assembly provided in Embodiment 3, viewed from another direction. The difference between this embodiment and Embodiments 1 and 2 is that, as... Figures 16-19 As shown, the limiting sidewall portion 110 includes a limiting latch 150, and the sidewall of the second air diffuser 200 is provided with a limiting protrusion 230. The limiting latch 150 engages with the limiting protrusion 230, and the limiting latch 150 and the base plate portion 120 are respectively located on both sides of the limiting protrusion 230. By providing the limiting latch 150, the limiting latch 150 can engage with the limiting protrusion 230 to prevent the second air diffuser 200 from disengaging from the first air diffuser 100 along the thickness direction, and even apply pressure to the second air diffuser 200, pressing it onto the first air diffuser 100. In conjunction with the limiting sidewall portion 110, the second air diffuser 200 is laterally limited, thus fixing the second air diffuser 200 to the first air diffuser 100.

[0090] Specifically, a limiting tongue 150 can be provided at the free end of the limiting sidewall portion 110 located on the long side of the rectangle. The limiting tongue 150 protrudes from the side of the limiting sidewall portion 110 toward the area enclosed by the limiting sidewall portion 110. Multiple limiting tongues 150 can be arranged along the length direction of the limiting sidewall portion 110 on the limiting sidewall portion 110. Furthermore, the free end of the limiting tongue 150 has a wedge-shaped portion with an inclined surface. When the first diffuser plate 100 is placed horizontally, the inclined surface gradually decreases in the direction away from the limiting sidewall portion 110. Thus, during the installation of the second diffuser plate 200 onto the first diffuser plate 100, the bottom of the second diffuser plate 200 can press against the wedge-shaped portion, causing the limiting sidewall portion 110 to bend away from the opposite limiting sidewall portion 110. The edge of the second diffuser plate 200 can pass through an area where the distance between the relatively short-distanced limiting tongues 150 is relatively short.

[0091] The limiting protrusion 230 can be located on the outer wall of the edge containing the long side of the roughly rectangular second air diffuser 200. Specifically, if the second air diffuser 200 is placed horizontally, a limiting groove 240 can be provided on the upper part of the side wall of the second air diffuser 200, and the limiting tongue 150 is inserted into the limiting groove 240. The limiting protrusion 230 is located below the limiting groove 240. The cross-section perpendicular to the length direction of the limiting groove 240 can be rectangular or square.

[0092] Furthermore, the end face of the free end of the limiting tongue 150 can match the side wall of the limiting groove 240. The two sides of the limiting side wall portion 110 where the limiting tongue 150 is located can match the end faces of the limiting groove 240 along its length. By utilizing the cooperation between the side of the limiting tongue 150 and the limiting groove 240, the second air diffuser 200 is limited.

[0093] like Figures 16-19 As shown, optionally, the air diffuser 130 includes a grid section, which includes multiple grid meshes. Each grid mesh includes planar rods 610 and planar air diffusers, which are enclosed by the planar rods 610 of each grid mesh. The grid section also includes three-dimensional inclined rods 620, which extend from the edge of the grid mesh. Multiple three-dimensional inclined rods 620 extending from the edge of the same grid mesh intersect, and the three-dimensional inclined rods 620 and the planar rods 610 intersect to form a three-dimensional air diffuser. In each air diffuser, the three-dimensional inclined rods 620 extend to the same side in the thickness direction of the grid section. By combining a grid mesh section with a three-dimensional inclined bar section 620 into the air diffuser section 130, the airflow can be diffused once using the grid mesh section, and also once using the three-dimensional air diffuser holes formed by the three-dimensional inclined bar sections 620 extending from the edge of the same grid mesh. This allows the airflow to be dispersed twice when passing through the same air diffuser plate by the planar air diffuser holes and the three-dimensional air diffuser holes, thereby improving the air diffusion effect. Moreover, since the three-dimensional air diffuser holes are inclined relative to the grid mesh section, the actual ventilation area of ​​the three-dimensional air diffuser holes is larger than the area of ​​the three-dimensional air diffuser holes projected onto the grid mesh along the thickness direction of the air diffuser plate. The total area of ​​multiple three-dimensional air diffuser holes may still be larger than the area of ​​the planar air diffuser holes, without reducing the ventilation area, thus ensuring a large airflow rate in the air diffuser section 130.

[0094] Specifically, in this embodiment, the grid mesh can be square. Of course, in other implementations, the grid mesh can also be rectangular or triangular. In this embodiment, the three-dimensional diagonal brace 620 can extend obliquely from the corner of the grid mesh. Of course, in other implementations, the three-dimensional diagonal brace 620 can extend from the center of the edge of the grid mesh.

[0095] Taking a square grid as an example in this embodiment, three-dimensional diagonal rods 620 extend from each of the four corners of the square. Triangles can be formed between the three-dimensional diagonal rods 620 and the planar rods 610. Since the plane containing these triangles is not the plane containing the planar air diffuser, the total area of ​​the multiple triangles can be greater than the area of ​​the planar air diffuser without reducing the ventilation area. Alternatively, in another implementation, a three-dimensional diagonal rod 620 can extend from each of the two opposite corners of the square. Or, the three-dimensional diagonal rods 620 can extend from three corners of the square or two adjacent corners, which can also disperse the airflow from the planar air diffuser.

[0096] Furthermore, the three-dimensional inclined rod portion 620 in this embodiment can be a straight rod. Of course, in other implementations, the three-dimensional inclined rod portion 620 can be an arc-shaped rod. For example, multiple three-dimensional inclined rod portions 620 can be located on the same ellipsoid or sphere, and the radial symmetry plane of the ellipsoid or sphere is located on the plane where the planar air diffuser is located.

[0097] like Figure 18 and Figure 19 As shown, optionally, multiple three-dimensional diagonal braces 620 extending from the edge of the same grid intersect at the same vertex 630. This arrangement allows the three-dimensional diagonal braces 620 to support each other, increasing their rigidity. Furthermore, it eliminates the possibility of small-section holes that might form when multiple three-dimensional diagonal braces 620 intersect at multiple points; these small-section holes, although through-holes, are essentially unable to provide ventilation. Therefore, this solution can increase the cross-sectional area of ​​each three-dimensional air diffuser hole enclosed by the three-dimensional diagonal braces 620 and the planar braces 610.

[0098] It should be noted that the projection of the same vertex portion 630 where multiple three-dimensional inclined rod portions 620 intersect along a direction perpendicular to the planar air diffuser should be located inside the planar air diffuser. Therefore, multiple three-dimensional inclined rod portions 620 intersecting at the same vertex portion 630 can disperse the airflow passing through the planar air diffuser.

[0099] like Figure 18 and Figure 19 As shown, optionally, multiple three-dimensional diagonal braces 620 extending from the edge of the same grid mesh and the grid mesh together form a regular polygonal pyramid. This arrangement maximizes and maintains the consistency of the area of ​​each three-dimensional air diffuser hole, resulting in a more uniform airflow distribution effect. Furthermore, since the three-dimensional diagonal braces 620 are edges of a regular polygonal pyramid, the stress on each three-dimensional diagonal brace 620 is consistent, preventing uneven stress on some parts of the three-dimensional diagonal braces 620 and thus avoiding inconsistent deformation or premature damage due to uneven load distribution.

[0100] In this embodiment, the same vertex 630 where multiple three-dimensional diagonal rods 620 intersect is projected along a direction perpendicular to the planar air diffuser hole and located at the geometric center of the planar air diffuser hole. In other words, the three-dimensional diagonal rods 620 extending from the corner of the same grid mesh and the planar rods 610 of the grid mesh together form a regular polygonal pyramid.

[0101] Specifically, in this embodiment, if the grid mesh is square, then the multiple three-dimensional oblique rods 620 are located at the edges of a regular square pyramid, and the multiple three-dimensional oblique rods 620 and the planar rods 610 form a regular square pyramid. If the grid mesh is equilateral triangular, then the multiple three-dimensional oblique rods 620 are located at the edges of a regular triangular pyramid, and the multiple three-dimensional oblique rods 620 and the planar rods 610 form a regular triangular pyramid. If the grid mesh is regular hexagonal, that is, the grid mesh is honeycomb-shaped, then the multiple three-dimensional oblique rods 620 are located at the edges of a regular hexagonal pyramid, and the multiple three-dimensional oblique rods 620 and the planar rods 610 form a regular hexagonal pyramid.

[0102] Optionally, the three-dimensional diagonal braces 620 on two adjacent diffuser plates in each group extend towards the other diffuser plate, and the intersecting apex portions 630 of the multiple three-dimensional diagonal braces 620 on each diffuser plate are correspondingly arranged and configured to abut against each other. This arrangement allows one diffuser plate to bear the airflow load on the other. Generally, since the velocity of the airflow within the diffuser assembly decreases overall, under the same conditions, the lower the airflow velocity, the smaller the force exerted on the diffuser plate. The diffuser plate on the upstream side of the airflow experiences a larger airflow force, while the diffuser plate on the downstream side experiences a smaller force. Therefore, when the apex portions 630 on the two diffuser plates abut against each other, the downstream diffuser portion 130 can partially bear the load of the upstream diffuser portion 130.

[0103] In this embodiment, two air diffusers are selected, forming a set of air diffusers. Of course, a single air diffuser assembly can also contain multiple sets of air diffusers; for example, two sets would result in four air diffusers, and three sets would result in six air diffusers. It should be noted that although the use of the limiting tongue 150 and the limiting protrusion 230 is described in the same embodiment as the air diffuser 130 including the grid mesh portion and the three-dimensional inclined rod portion 620, those skilled in the art should understand that the connection method using the limiting tongue 150 and the limiting protrusion 230 is not limited to the case where the air diffuser 130 includes the grid mesh portion and the three-dimensional inclined rod portion 620. For example, when using the limiting tongue 150 and the limiting protrusion 230, the air diffuser 130 can also take the form of the air diffuser 130 in Embodiments 1 and 2. Similarly, the connection method of the first air diffuser plate 100 and the second air diffuser plate 200 described in Embodiments 1 and 2 can also be used in conjunction with the air diffuser section 130 in Embodiment 3.

[0104] Optionally, the number of three-dimensional diagonal braces 620 connected to each grid mesh is m < n, and m ≥ 2, where n is the number of sides of the grid mesh; in two adjacent diffuser plates, the projection of the three-dimensional diagonal braces 620 of each diffuser plate along the thickness direction of the diffuser assembly is located within the three-dimensional diffuser holes of the other diffuser plate. This arrangement of the three-dimensional diagonal braces 620 ensures that after the airflow passes through the three-dimensional diffuser holes on one diffuser plate, it is dispersed by the three-dimensional diagonal braces 620 on the other diffuser plate, thereby reducing the airflow velocity and achieving multiple dispersion of the outlet airflow. Furthermore, it reduces material usage and lowers production costs.

[0105] Specifically, taking a square grid as an example, the grid has four sides and four corners. Two three-dimensional diagonal sections 620 can be set at opposite corners of each grid. When the two diffusers are placed horizontally, the three-dimensional diagonal sections 620 extending from the grid of the second diffuser 200 can be set along the northeast-southwest direction, while the three-dimensional diagonal sections 620 extending from the corresponding grid of the first diffuser 100 can be set along the northwest-southeast direction. The airflow passing through the three-dimensional diffuser holes at the northwest and southeast corners of the second diffuser 200 intersects with and is dispersed by the three-dimensional diagonal sections 620 set in the northwest-southeast direction of the first diffuser 100, thus reducing the airflow velocity. Of course, in another implementation, if the grid is square, three-dimensional diagonal braces 620 can be set at the northwest, southeast, and southwest corners of one grid, and at the northwest, northeast, and southeast corners of the grid of another diffuser. This also falls under the case where the projection of the three-dimensional diagonal braces 620 extending from the corresponding grid of one diffuser falls on the three-dimensional air vent of the other diffuser. If the grid is regular hexagonal, three-dimensional diagonal braces 620 can extend from three alternating corners of the grid of one diffuser, and from another set of three alternating corners of the grid of another diffuser. Alternatively, three-dimensional diagonal braces 620 can be drawn from the diagonal positions of the regular hexagon, and the three-dimensional diagonal braces 620 of the grid of each of the two adjacent diffusers fall on the three-dimensional air vent of the other diffuser.

[0106] Optionally, the grid section and the three-dimensional diagonal bar section 620 on two adjacent air diffuser plates in each group are mirror-symmetrical. This arrangement allows for greater uniformity in the molds used to manufacture the air diffuser plates, which helps reduce manufacturing costs. Each air diffuser assembly can have one set of air diffuser plates or multiple sets of air diffuser plates, as detailed above and will not be repeated here.

[0107] Example 4: Figure 20 This is a schematic diagram of the structure of the wall-mounted indoor unit of the air conditioner provided in Embodiment 4. Figure 21 This is a schematic diagram of the structure of a wall-mounted indoor unit in an air conditioner, as provided in Embodiment 4, for another implementation method. Figure 20 and Figure 21 As shown, Embodiment 4 also provides an air conditioner, including an indoor unit and an outdoor unit. The indoor unit has an air vent assembly as described above installed at its air outlet. The indoor and outdoor units are connected via a refrigerant connection pipe. By incorporating the aforementioned air vent assembly into the air conditioner, the air conditioner possesses all the advantages of the aforementioned air vent assembly, which will not be elaborated further here.

[0108] Specifically, such as Figure 21As shown, taking a wall-mounted air conditioner indoor unit as an example, in this embodiment, the air diffuser assembly can be fixedly installed at the front and lower air outlets of the air conditioner indoor unit to disperse the airflow from the unit, giving the user a feeling of zero wind. Among the multiple air diffusers, the diffuser located downstream in the airflow direction can be fixed to the main body of the wall-mounted air conditioner indoor unit, for example, using clips, magnets, or screws.

[0109] like Figures 23-24 As shown, optionally, when the air conditioner is in zero-wind mode, the first air diffuser 100 is located on the leeward side of the second air diffuser 200. With this configuration, the direction of the airflow is such that the second air diffuser 200 is closer to the first air diffuser 100, and the overall velocity of the airflow within the diffuser assembly decreases. Therefore, the airflow force on the second air diffuser 200 is greater than the airflow force on the first air diffuser 100. In other words, the force exerted by the airflow on each diffuser is such that the force on the second air diffuser 200 closer to the first air diffuser 100 is greater than the force on the first air diffuser 100 farther from the second air diffuser 200. If the diffuser assembly is fixedly installed in the main body of the indoor unit of the air conditioner, then fixing the first air diffuser 100 will also allow for the fixing of the second air diffuser 200. If the air diffuser assembly is rotatably installed inside the air conditioner body, the rotating shaft 220 of the air diffuser assembly can be set on the second air diffuser plate 200 to avoid setting it on the first air diffuser plate 100 and interfering with the connection between the first air diffuser plate 100 and the second air diffuser plate 200.

[0110] Specifically, taking a wall-mounted air conditioner indoor unit as an example, in this embodiment, the air diffusion assembly including the first air diffuser 100 and the second air diffuser 200 can be used as upper and lower sweeping blades set at the air outlet of the air conditioner. Specifically, the wall-mounted air conditioner indoor unit includes a housing, with an air inlet 710 at the top of the housing, an indoor heat exchanger 720 in the housing, and an indoor fan below the indoor heat exchanger 720. Driven by the indoor fan, air exchanges heat with the indoor heat exchanger 720 and flows out from the air outlet duct. A front lower air outlet 730 is provided at the lower part of the front surface of the air conditioner, and a front lower air diffusion assembly 740 is correspondingly provided. The rotation axis of the front lower air diffusion assembly 740 is located at the rear side of its lower part. A lower front air outlet 750 is provided at the front of the lower surface of the air conditioner, and a lower front air diffusion assembly 760 is correspondingly provided. The rotation axis of the lower front air diffusion assembly 760 is located at the upper rear part of its rear part.

[0111] If the opening of the lower front air outlet 730 is in a vertical plane and the lower front diffuser assembly 740 is in a vertical state, and if the lower front air outlet 730 still has air coming out, the airflow will pass through the lower front diffuser assembly 740 to generate a zero-wind airflow that can change the indoor temperature but will not produce a noticeable draft. If the lower front air outlet 750 is in a horizontal plane and the lower front diffuser assembly 760 is in a horizontal state, and if the lower front air outlet 750 still has air coming out, the airflow will pass through the lower front diffuser assembly 760 to generate a zero-wind airflow that can change the indoor temperature but will not produce a noticeable draft.

[0112] Figure 24 The diagram shows the air conditioner in a zero-airflow state. The front lower diffuser assembly 740 is in a vertical position and blocks the front lower air outlet 730, while the lower front diffuser assembly 760 is in a horizontal position and blocks the lower front air outlet 750. Therefore, the airflow discharged from the front lower air outlet 730 and the lower front air outlet 750 are both zero-airflow airflow. Figure 25 The diagram shows the air conditioner in cooling mode. The front lower diffuser assembly 740 has a small angle with the horizontal plane, for example, 2°~10°, allowing the front lower air outlet 730 to open to a greater extent, supplying airflow that is generally discharged forward from the front lower air outlet 730. In the diagram, the lower front diffuser assembly 760 has an angle with the horizontal plane of 20°~40°, allowing airflow to be discharged in a slightly downward direction from the lower front air outlet 750. Therefore, the cold air discharged from both the front lower air outlet 730 and the lower front air outlet 750 has a small angle with the ground, which can better cool areas with higher ceilings in the room, creating a more uniform cooling effect. Although both the front lower air diffuser assembly 740 and the lower front air diffuser assembly 760 are provided with air diffuser holes 300, and theoretically the airflow can pass through the air diffuser holes 300, since both the front lower air diffuser assembly 740 and the lower front air diffuser assembly 760 open their respective air outlets, the airflow is mainly or even almost entirely discharged from the corresponding air outlets, and the amount discharged from the air diffuser assembly is negligible. Figure 26 The diagram shows the air conditioner in heating mode, with the front lower diffuser assembly 740 in a vertical position. In the diagram, the front lower diffuser assembly 760 forms an angle of 75°~85° with the horizontal plane, allowing airflow to be primarily discharged downwards from the front lower air outlet 750. Since the front lower air outlet 750 is open, although theoretically airflow can pass through the diffuser holes 300 of the front lower diffuser assembly 740, the resistance to airflow exiting through the front lower air outlet 750 is far less than the resistance through the front lower diffuser assembly 740. The proportion of zero-wind-feel airflow formed by the airflow through the diffuser holes 300 from the front lower diffuser assembly 740 is almost negligible. The airflow is mainly, or almost entirely, discharged from the front lower air outlet 750. Therefore, in this state, hot air is discharged from the front lower air outlet 750, heating areas with lower ceiling height in the room to improve the uniformity of indoor temperature distribution.

[0113] Of course, in the above illustrations, both the front lower air outlet 730 and the lower front air outlet 750 only show one air diffuser component in their width direction, not in the left-right direction of the wall-mounted air conditioner indoor unit. In reality, in another implementation, multiple air diffusers are arranged along the width direction of the front lower air outlet 730 and the lower front air outlet 750. The width of the air diffusers is used to achieve the air guiding function.

[0114] In this embodiment, a diffuser assembly of Embodiment 1 or Embodiment 2 is provided at the lower front air outlet 750, and a diffuser assembly of Embodiment 3 is provided at the lower front air outlet 730. In fact, the types of diffuser assemblies provided at different air outlets can be interchanged, or the same type of diffuser assembly can be provided, or the connection methods of the first diffuser plate 100 and the second diffuser plate 200 and the specific structure of the diffuser section 130 in Embodiments 1, 2 and 3 can be combined.

[0115] Furthermore, if the air diffuser assembly is rotatably installed within the air conditioner unit, the rotating shaft 220 of the air diffuser assembly can be positioned on the second air diffuser plate 200 to avoid interfering with the connection between the first air diffuser plate 100 and the second air diffuser plate 200 if positioned on the first air diffuser plate 100. Specifically, if the direction in which the second air diffuser plate 200 is installed on the first air diffuser plate 100 is the length direction of the air diffuser assembly, for example, by inserting it along this direction, placing the rotating shaft 220 on the first air diffuser plate 100 would interfere with the insertion of the second air diffuser plate 200. If the direction in which the second air diffuser plate 200 is installed on the first air diffuser plate 100 is the thickness direction of the air diffuser assembly, placing the rotating shaft 220 on the first air diffuser plate 100 would result in a larger thickness in the area near the rotating shaft 220 of the first air diffuser plate 100, leading to uneven thickness of the injection molded part and thus reducing the quality of the injection molded product. To ensure that the thickness is close, the area near the pivot 220 needs to be set as a recessed part 400, which will also disrupt the airflow on the windward surface of the diffuser assembly and may increase the noise of the air conditioner indoor unit.
