Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to a panel structure of an air conditioner outdoor unit and the air conditioner outdoor unit. Background Art

[0002] Generally, the panel structure of the air conditioner outdoor unit includes a front panel and a mesh cover, wherein the front panel is made of sheet metal, the mesh cover is made of plastic or steel mesh, and the mesh cover is fixed to the front panel by assembly structures such as buckles and screws to form a grille structure for air outlet on the front panel. The above panel structure is not only inefficient in assembly, but also, in order to install the mesh cover, it is necessary to punch the middle part of the front panel, and the punched middle part of the front panel forms waste, which cannot fully utilize the raw materials for production and causes cost waste. Utility Model Content

[0003] The first object of the utility model is to provide a panel structure of an air conditioner outdoor unit to solve the technical problem that the panel structure of the existing air conditioner outdoor unit not only has low assembly efficiency but also causes cost waste.

[0004] The panel structure of the air conditioner outdoor unit provided by the utility model comprises a front panel, wherein the front panel is stamped with an air outlet grille, and the air outlet grille comprises a plurality of grille holes, wherein the edges of the grille holes are formed with a flange structure.

[0005] The panel structure can obtain an air outlet grille directly on the front panel by stamping the front panel, and the air outlet grille can be used to achieve the air outlet function of the traditional mesh cover, thereby realizing the integration of the front panel and the mesh cover. Through the above arrangement, on the one hand, the assembly process is reduced, and the cumbersome process of assembling the front panel and the mesh cover required by the previous panel structure can be omitted, thereby improving the assembly efficiency. On the other hand, since there is no need to stamp the front panel to obtain the air circle hole, only the air outlet grille with a flow area smaller than the flow area of ​​the air circle hole is stamped on the front panel, thereby reducing the waste of the raw materials for the production of the front panel, so that the raw materials for the production of the front panel can be fully utilized, thereby achieving cost reduction and efficiency improvement.

[0006] In addition, by forming a flange structure at the edge of the grille hole, the structural strength of the front panel can be improved, which can not only suppress the deformation of the front panel at the air outlet grille position to ensure the assembly reliability of the front panel, but also extend the service life of the front panel.

[0007] Furthermore, the flange structure is folded toward the inner cavity of the casing of the air conditioner outdoor unit. This arrangement allows the flange structure to be hidden behind the front panel after the panel structure is assembled to the casing of the air conditioner outdoor unit. On the one hand, it can prevent the flange structure from being exposed and scratching the hands, thereby improving the safety of the panel structure during use. On the other hand, it can also ensure the aesthetic appearance of the structure of the air conditioner outdoor unit after the panel structure is assembled.

[0008] Furthermore, the air outlet grille includes annular ribs arranged in multiple circles, and radial ribs connecting the multiple circles of the annular ribs, wherein the annular ribs and the radial ribs are both formed with the flange structure. This arrangement can not only ensure the structural strength of the air outlet grille, but also ensure that the air outlet area of ​​the air outlet grille is not too small, thereby ensuring the air volume of the air conditioner outdoor unit.

[0009] Furthermore, the flange structure includes a first flange and a second flange, and the first flange and the second flange are arranged relative to each other in an "eight" shape, wherein the closing opening formed by the first flange and the second flange faces the inner cavity of the housing, and the flaring opening formed by the first flange and the second flange faces away from the inner cavity of the housing. This arrangement enables one of the first flange and the second flange to be tilted upward and the other to be tilted downward from the inside of the housing to the outside, so that in the process of using the panel structure to discharge air, the air blown out by the fan assembly can be blown out after being guided by the first flange and the second flange, thereby reducing the air outlet resistance caused by the air outlet grille and increasing the air outlet volume.

[0010] Furthermore, the cross-sections of the annular ribs and the radial ribs are both triangular structures, and the two sides of the triangular structure form the first flange and the second flange. With this arrangement, when the annular ribs are formed into flange structures, the flange structures can be obtained by only bending the inner edge and the outer edge of the annular ribs once respectively, which simplifies the manufacturing process and has high forming efficiency. Similarly, this arrangement also makes the forming of the radial ribs highly efficient.

[0011] Furthermore, the triangular structure is an isosceles triangle structure. Through this arrangement, the forming process of the first flange and the second flange can be obtained by using a mold of the same specification, thereby reducing the production cost.

[0012] Furthermore, the angle formed by the first flange and the second flange is B, wherein 50°≤B≤85°. This arrangement can, on the one hand, avoid the inability to guide the airflow and affect the airflow due to the angle between the first flange and the second flange being too small, and on the other hand, avoid the cross collision of the airflow when it is blown out between two adjacent annular ribs or two adjacent radial ribs due to the angle between the first flange and the second flange being too large, thereby affecting the airflow.

[0013] Furthermore, along the thickness direction of the panel structure, the size of the flange structure is H, where 3t≤H≤5t, and t is the thickness of the front panel. This arrangement can, on the one hand, avoid the failure of the flange structure to guide the airflow due to the flange structure being too small, and on the other hand, can reduce the occupation of the internal space of the casing by the panel structure. At the same time, it can also avoid the collision and interference with the internal structure of the casing during the assembly of the panel structure due to the flange structure being too large.

[0014] Furthermore, the panel structure is a sheet metal part. This arrangement can not only ensure the strength of the panel structure and reduce the weight of the panel structure, but also facilitate large-scale mass production and help improve production efficiency.

[0015] The second purpose of the utility model is to provide an air conditioner outdoor unit to solve the technical problem that the panel structure of the existing air conditioner outdoor unit not only has low assembly efficiency but also causes cost waste.

[0016] The utility model provides an air conditioner outdoor unit, comprising a casing and a fan assembly arranged in the inner cavity of the casing, the casing is provided with the above-mentioned panel structure, and the air outlet grille of the panel structure is opposite to the fan assembly.

[0017] By setting the above panel structure in the air conditioner outdoor unit, the air conditioner outdoor unit accordingly has all the advantages of the above panel structure, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Figure 1 This is a schematic diagram of the exploded structure of the panel of the air conditioner outdoor unit provided by the prior art. Figure 1 As shown, in the prior art, the panel structure of the air conditioner outdoor unit includes a front panel 100' and a mesh cover 200', and the mesh cover 200' is fixed to the front panel 100' by means of assembly structures such as buckles and screws. This panel structure not only has low assembly efficiency, but also causes waste because the middle part of the front panel 100' is punched out to form waste.

[0034] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] Figure 2 A three-dimensional schematic diagram of the panel structure of the air conditioner outdoor unit provided in this embodiment; Figure 3 This is a front view of the panel structure of the air conditioner outdoor unit provided in this embodiment. Figure 2 and Figure 3 As shown, this embodiment provides a panel structure of an air conditioner outdoor unit, including a front panel 010, the front panel 010 is stamped with an air outlet grille 100, the air outlet grille 100 includes a plurality of grille holes 130, wherein the edges of the grille holes 130 are formed with a flange structure 140.

[0036] The panel structure can obtain the air outlet grille 100 directly on the front panel 010 by stamping the front panel 010, and the air outlet grille 100 can be used to achieve the air outlet function of the traditional mesh cover, thereby realizing the integration of the front panel 010 and the mesh cover. Through the above arrangement, on the one hand, the assembly process is reduced, and the cumbersome process of assembling the front panel 010 and the mesh cover required by the previous panel structure can be omitted, thereby improving the assembly efficiency. On the other hand, since there is no need to stamp the front panel 010 to obtain the air circle hole, only the air outlet grille 100 with a flow area smaller than the flow area of ​​the air circle hole is stamped on the front panel 010, thereby reducing the waste of the production raw materials of the front panel 010, so that the production raw materials of the front panel 010 can be fully utilized, thereby realizing cost reduction and efficiency improvement.

[0037] In addition, by forming a flange structure 140 at the edge of the grille hole 130, the structural strength of the front panel 010 can be improved, which can not only suppress the deformation of the front panel 010 at the position of the air outlet grille 100 to ensure the assembly reliability of the front panel 010, but also extend the service life of the front panel 010.

[0038] Figure 4 A left side view of the panel structure of the air conditioner outdoor unit provided in this embodiment; Figure 5 for Figure 4 The enlarged view of the local structure at M in the figure. Figure 4 and Figure 5 As shown, the flange structure 140 is folded toward the inner cavity of the casing of the air conditioner outdoor unit.

[0039] By setting the flange structure 140 to be folded toward the inner cavity of the casing of the air-conditioning outdoor unit, after the panel structure is assembled to the casing of the air-conditioning outdoor unit, the flange structure 140 is hidden at the rear of the front panel 010. On the one hand, it can prevent the flange structure 140 from being exposed and scratching the hands, thereby improving the safety of the panel structure during use. On the other hand, it can also ensure the structural aesthetics of the air-conditioning outdoor unit after the panel structure is assembled.

[0040] Please continue to refer to Figure 2 and Figure 3 In this embodiment, the air outlet grille 100 includes annular ribs 110 arranged in multiple circles, and radial ribs 120 connecting the multiple circles of annular ribs 110, wherein the annular ribs 110 and the radial ribs 120 are both formed with a flange structure 140.

[0041] By setting the air outlet grille 100 to the above-mentioned structural form mainly composed of radial ribs 120 and multiple circles of annular ribs 110, not only can the structural strength of the air outlet grille 100 be ensured and the deformation generated at the position of the air outlet grille 100 be further reduced, but it can also ensure that the air outlet area of ​​the air outlet grille 100 is not too small, thereby ensuring the air volume of the air conditioner outdoor unit and improving the performance of the air conditioner outdoor unit.

[0042] Please continue to refer to Figure 2 and Figure 3 In this embodiment, a plurality of radial ribs 120 are provided, wherein a portion of the radial ribs 120 are long ribs connecting all the annular ribs 110, and another portion of the radial ribs 120 are short ribs connecting some of the annular ribs 110, and a plurality of long ribs and a plurality of short ribs are arranged alternately.

[0043] Please continue to refer to Figure 5 In this embodiment, the flange structure 140 includes a first flange 141 and a second flange 142, and the first flange 141 and the second flange 142 are arranged opposite to each other in an "eight" shape, wherein the closing opening 143 formed by the first flange 141 and the second flange 142 faces the inner cavity of the casing, and the expanding opening 144 formed by the first flange 141 and the second flange 142 faces away from the inner cavity of the casing.

[0044] The above-mentioned arrangement of the flange structure 140, on the one hand, makes it possible for one of the first flange 141 and the second flange 142 to be tilted upward and the other to be tilted downward from the inside of the casing to the outside, so that in the process of using the panel structure to exhaust air, the air blown out by the fan assembly can be blown out after being guided by the first flange 141 and the second flange 142, thereby reducing the air outlet resistance caused by the air outlet grille 100 and increasing the air outlet volume; on the other hand, this arrangement also makes each edge of the grille hole 130 have the flange structure 140, ensuring the force balance of the grille hole 130 at its edge position, thereby effectively suppressing the deformation of the panel structure.

[0045] Please continue to refer to Figure 5 In this embodiment, the cross-sections of the annular ribs 110 and the radial ribs 120 are both triangular structures, wherein the two sides of the triangular structure form the first flange 141 and the second flange 142, and the base of the triangle forms the rib body of the annular ribs 110 and the radial ribs 120.

[0046] Through this arrangement, when the annular rib 110 is formed into the flange structure 140, the flange structure 140 can be obtained by bending the inner edge and the outer edge of the annular rib 110 once respectively, which simplifies the manufacturing process and has high forming efficiency. Similarly, this arrangement also makes the forming of the radial rib 120 highly efficient.

[0047] In other embodiments, the edge of the annular rib 110 or the radial rib 120 may be folded multiple times to obtain the first flange 141 and the second flange 142 .

[0048] Please continue to refer to Figure 5 In this embodiment, the triangular structure is an isosceles triangular structure. That is, in each set of flange structures 140, the first flange 141 and the second flange 142 are arranged in mirror symmetry, that is, the first flange 141 and the second flange 142 have the same inclination angle (different inclination directions), and the first flange 141 and the second flange 142 have the same folding length.

[0049] Through this arrangement, on the one hand, the molding process of the first flange 141 and the second flange 142 can be obtained by using a mold of the same specification, thereby reducing the production cost. On the other hand, when the air blown out by the fan assembly flows through the grille hole 130, the air flow velocity at the two opposite edges of the annular rib 110 and the radial rib 120 is the same, thereby obtaining a stable air flow at the front end of the panel structure.

[0050] Please continue to refer to Figure 5 In this embodiment, the angle formed by the first flange 141 and the second flange 142 is B, wherein 50°≤B≤85°.

[0051] By limiting the angle formed by the first flange 141 and the second flange 142 to the above range, on the one hand, it can be avoided that the first flange 141 and the second flange 142 are too small, which results in the inability to guide the airflow and affect the wind output. On the other hand, it can also be avoided that the airflow is blown out between two adjacent annular ribs 110 or two adjacent radial ribs 120 due to the angle between the first flange 141 and the second flange 142 is too large, which causes the cross collision and affects the air output.

[0052] Please continue to refer to Figure 5 In this embodiment, along the thickness direction of the panel structure, the dimension of the flange structure 140 is H, where 3t≤H≤5t, and t is the thickness of the front panel 010. For example, when the thickness of the front panel 010 is 1 mm, the dimension H of the flange structure 140 is in the range of 3mm≤H≤5mm.

[0053] By limiting the size of the flange structure 140 within the above range, on the one hand, it is possible to avoid the failure of the flange structure 140 to guide the outlet air flow due to the flange structure 140 being too small. On the other hand, it is possible to reduce the space occupied by the panel structure inside the casing. At the same time, it is also possible to avoid the flange structure 140 being too large and causing collision and interference with the structure inside the casing during the assembly of the panel structure.

[0054] In this embodiment, the panel structure is a sheet metal part. That is, the front panel 010 is a sheet metal part, and the air outlet grille 100 is obtained by stamping the sheet metal part.

[0055] The panel structure adopts the setting form of sheet metal parts, which not only ensures the strength of the panel structure and reduces the weight of the panel structure, but also facilitates large-scale mass production and is conducive to improving production efficiency.

[0056] The manufacturing process of the flange structure 140 of the air outlet grille 100 of the panel structure can be as follows.

Figure 1 ; Figure 7 The forming process of the panel structure of the air conditioner outdoor unit provided in this embodiment is schematically shown. Figure 2 ; Figure 8 The forming process of the panel structure of the air conditioner outdoor unit provided in this embodiment is schematically shown. Figure 3 ; Fig. 9 The forming process of the panel structure of the air conditioner outdoor unit provided in this embodiment is schematically shown. Figure 4 .

[0058] like Figure 6As shown, the front panel 010 can be punched using the first die 020. Specifically, the front panel 010 is placed in the first fixed die 021, the first movable die 022 and the first fixed die 021 are arranged to be openable and closable, and the first punch 023 is pressed downward to obtain the front panel 010 in the first form 011. At this time, the grille hole 130 is obtained in the front panel 010.

[0059] like Figure 7 As shown, the second die 030 can be used to flange the front panel 010. Specifically, the front panel 010 of the first form 011 is placed on the second fixed die 031, the second movable die 032 and the second fixed die 031 are arranged to be openable and closable, and the second punch 033 is used to press down to obtain the front panel 010 of the second form 012. At this time, the edge of the grille hole 130 forms a flange, and the flange is roughly perpendicular to the front panel 010.

[0060] like Figure 8 and Fig. 9 As shown, the flange is finally formed by the third mold 040 to obtain the flange structure 140. Specifically, the front panel 010 of the second form 012 is placed on the top rod 043 of the third fixed mold 041, wherein a fixed plate 045 is installed at the lower end of the third fixed mold 041, and a spring 044 is arranged between the top rod 043 and the fixed plate 045; the third movable mold 042 and the third fixed mold 041 are arranged to be openable and closable, and the third fixed mold 041 is provided with a molding groove 0411 at a position opposite to the flange. The downward pressing action of the third movable mold 042 can drive the front panel 010 of the second form 012 to descend, so that the flange is finally formed by the inclined surface of the molding groove 0411, and the first flange 141 and the second flange 142 in the shape of "eight" are obtained, thereby obtaining the front panel 010 of the third form 013. After the above-mentioned flange structure 140 is formed, the third movable mold 042 is opened, and the push rod 043 pushes the front panel 010 of the third form 013 upward under the elastic restoring force of the spring 044, thereby obtaining the air outlet grille 100.

[0061] It should be noted that the above Figures 6 to 9 Only the production process of the flange structure 140 at one grille hole 130 of the front panel 010 is demonstrated. The same production process can be adopted for other grille holes 130, and this embodiment will not be described in detail with reference to the drawings.

[0062] In addition, this embodiment also provides an air conditioner outdoor unit, including a casing and a fan assembly arranged in the inner cavity of the casing, wherein the casing is provided with the above-mentioned panel structure, and the air outlet grille 100 of the panel structure is opposite to the fan assembly.
