Description

Technical Field

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

[0002] The outdoor unit of a split-type air conditioner has an air outlet grille on its front panel, which contains a heat exchanger, fan, compressor, etc. The compressor is used to compress the refrigerant, the heat exchanger is used to exchange heat between the refrigerant and the gas in the outdoor unit, and the fan is used to discharge the gas in the outdoor unit from the air outlet grille to accelerate the flow of the gas in the outdoor unit, thereby improving the heat exchange efficiency of the outdoor unit.

[0003] However, in the prior art, the air output of the outdoor unit of the air conditioner is still relatively small, resulting in a relatively low heat exchange efficiency. Utility Model Content

[0004] The first purpose of the present utility model is to provide a front panel of an outdoor unit to solve the technical problems in the prior art of small air output and low heat exchange efficiency of the outdoor unit of the air conditioner.

[0005] The utility model provides an outdoor unit front panel, including a panel portion, a guide ring portion and an air outlet grille portion, which are integrated into one piece, and the guide ring portion protrudes outward from the panel portion, and the air outlet grille portion is arranged at the air outlet end of the guide ring portion; the air outlet grille portion includes a connecting portion located in the center and a plurality of bars located between the connecting portion and the air outlet end of the guide ring portion, the two ends of the bars are twisted in the same direction by stamping, and the main body of the bars located between the two ends is tilted to a preset air guide angle with respect to the air outlet direction.

[0006] The outdoor unit front panel provided by the utility model can produce the following beneficial effects:

[0007] The utility model provides an outdoor unit front panel, in which the bars of the air outlet grille are stamped and twisted at both ends in the same direction, and the main body is tilted to a preset air guide angle with respect to the air outlet direction, wherein the tilting of the main body of the bar can make way for the air outlet channel, thereby expanding the air outlet area, and further increasing the air outlet volume and improving the heat exchange efficiency; and the main body of the bar is tilted to a preset air guide angle with respect to the air outlet direction, so that the bar can play a good air guiding role, thereby further increasing the air outlet volume, improving the heat exchange efficiency and improving the air outlet effect.

[0008] In addition, the air outlet grille portion is formed by stamping, which has a simple process and high production efficiency, and is conducive to the panel portion, the guide ring portion and the air outlet grille portion being stamped into an integrated form of the outdoor unit front panel. The integrated setting of the three makes the front panel more integrated, thereby having higher structural strength, better appearance consistency and more beautiful appearance. It can also be assembled in an integrated manner, thereby greatly simplifying the assembly process of the outdoor unit and improving assembly efficiency; when disassembling, it can also be disassembled in an integrated manner.

[0009] In addition, when the maximum thickness of the outdoor unit along the front and rear directions is consistent, the front panel of the outdoor unit provided by the utility model has a guide ring portion that is protruding relative to the panel portion, which is actually equivalent to reducing the distance between the panel portion of the front panel and the rear wall panel of the outdoor unit casing. The main body thickness or average thickness of the entire outdoor unit is actually reduced, making it more miniaturized, thereby reducing space occupancy.

[0010] Furthermore, a circumferential support rib is provided between the connecting portion and the air outlet end of the guide ring portion, and the bars include inner and outer ring bars, wherein the inner ring bars are connected between the connecting portion and the inner side of the circumferential support rib, and the outer ring bars are connected between the outer side of the circumferential support rib and the air outlet end of the guide ring portion. Under this technical solution, by providing inner and outer ring bars, the distance between the outer ends of two circumferentially adjacent bars away from the central connecting portion can be effectively controlled, that is, the size of the air outlet can be effectively controlled, so that the air outlet grille portion can not only ensure the air outlet volume, but also effectively prevent foreign matter from entering the housing of the outdoor unit through the air outlet grille portion.

[0011] Optionally, a plurality of the grating bars are arranged at intervals along the circumferential direction, and in the radial direction, the inner ends of the grating bars are connected to the connecting portion, and the outer ends are connected to the air outlet end of the guide ring portion. This technical solution is more suitable for situations where the radial distance between the central connecting portion and the air outlet end of the guide ring portion is relatively small or the air outlet can be set to be relatively large.

[0012] Optionally, at least two circumferential support ribs are provided between the connecting portion and the air outlet end of the guide ring portion, and the bars include inner, middle, and outer ring bars. The inner ring bars are connected between the connecting portion and the inner sides of adjacent circumferential support ribs, the middle ring bars are connected between two adjacent circumferential support ribs, and the outer ring bars are connected between the air outlet end of the guide ring portion and the outer sides of adjacent circumferential support ribs. This technical solution is more suitable for situations where the radial distance between the central connecting portion and the air outlet end of the guide ring portion is relatively large or the air outlet needs to be set relatively small.

[0013] Furthermore, in the radial direction, the number of the bars outside the circumferential support ribs is greater than the number of the bars inside the circumferential support ribs. By increasing the number of bars in the outer ring, the maximum distance between two adjacent bars can be effectively controlled, that is, the size of each air outlet can be controlled.

[0014] Furthermore, the plurality of bars extend radially, and the plurality of bars in each circle are uniformly arranged circumferentially. Under this technical solution, the bars all extend radially, thus simplifying the design of the corresponding bar mold. Alternatively, the bars can extend radially and have a curvature. The uniform circumferential arrangement of the plurality of bars in each circle effectively ensures that the air outlets of adjacent bars are of uniform size, thereby ensuring a relatively consistent airflow effect along the circumference of the air outlet grille portion.

[0015] Furthermore, the main body of the grid bar is flat, and the angle between the main body and the normal plane of the axis of the air outlet grille portion is in the range of 60° to 80°, preferably 70°. Under this technical solution, the shape of the grid bar is relatively simple, so the design of the corresponding mold and the stamping process are relatively simple.

[0016] Furthermore, the cross-section of the main body of the grating is arc-shaped, and the tangent plane of the main body on the air outlet side is parallel to the axis of the air outlet grille portion. The angle between the tangent plane on the air inlet side of the main body and the tangent plane on the air outlet side is in the range of 25° to 40°. That is, the central angle corresponding to the cross-section of the main body is in the range of 25° to 40°, preferably 32°. Under this technical solution, the grating has a curvature from its air inlet side to its air outlet side, and the grating has a better air guiding effect.

[0017] Optionally, a plurality of radial support ribs are connected between the connecting portion and the air outlet end of the guide ring portion, the plurality of radial support ribs are arranged at intervals along the circumferential direction, and any two adjacent radial support ribs are connected to a plurality of bars arranged at intervals along the radial direction.

[0018] The second purpose of the present invention is to provide an outdoor unit to solve the technical problems in the prior art of the outdoor unit of the air conditioner, such as small air volume and low heat exchange efficiency.

[0019] The outdoor unit provided by the present invention includes the above-mentioned outdoor unit front panel. Therefore, the outdoor unit has all the advantages of the above-mentioned outdoor unit front panel, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] This embodiment provides an outdoor unit front panel, such as Figures 1 to 10 As shown, the indoor unit front panel includes a panel portion 100, a guide ring portion 200, and an air outlet grille portion 300. The three are integrated, with the guide ring portion 200 protruding outward from the panel portion 100. The air outlet grille portion 300 is arranged at the air outlet end of the guide ring portion 200. The air outlet grille portion 300 includes a central connecting portion 310 and a plurality of bars 320 located between the connecting portion 310 and the air outlet end of the guide ring portion 200. The two ends of the bars 320 are twisted in the same direction by stamping, so that the main body 323 of the bars 320 located between the two ends is tilted to form a preset air guide angle with respect to the air outlet direction. The preset air guide angle can range from 16° to 20°.

[0037] The outdoor unit front panel provided in this embodiment has bars 320 of the air outlet grille portion 300 that are punched and twisted at both ends in the same direction, and the main body 323 is tilted to a preset wind guide angle with respect to the air outlet direction, wherein the main body 323 of the bar 320 is tilted to make way for the air outlet channel, thereby expanding the air outlet area, and further increasing the air outlet volume and improving the heat exchange efficiency; and the main body 323 of the bar 320 is tilted to a preset wind guide angle with respect to the air outlet direction, so that the bar 320 can play a good wind guiding role, thereby further increasing the air outlet volume, improving the heat exchange efficiency and improving the air outlet effect.

[0038] In addition, the air outlet grille portion 300 is formed by stamping, which has a simple process and high production efficiency, and is conducive to the panel portion 100, the guide ring portion 200 and the air outlet grille portion 300 being stamped into an integral part to form the front panel of the outdoor unit. The integrated setting of the three makes the integrity of the front panel better, thereby having higher structural strength, better appearance consistency and more beautiful appearance, and can also be assembled in an integrated manner, thereby greatly simplifying the assembly process of the outdoor unit and improving assembly efficiency; when disassembling, it can also be disassembled in an integrated manner.

[0039] In addition, when the maximum thickness of the outdoor unit along the front and rear directions is consistent, the front panel of the outdoor unit provided in this embodiment has a guide ring portion 200 that is protruding relative to the panel portion 100, which is actually equivalent to reducing the distance between the panel portion 100 of the front panel and the rear wall panel of the outdoor unit casing. The main body thickness or average thickness of the entire outdoor unit is actually reduced, making it more miniaturized, thereby reducing space occupancy.

[0040] Specifically, in this embodiment, Figure 4 and Figure 5 as well as Figure 9 and Figure 10 As shown, a circumferential support rib 330 is provided between the connection portion 310 and the air outlet end of the guide ring portion 200, and the bars 320 include inner and outer ring bars. The inner ring bars are connected between the connection portion 310 and the inner side of the circumferential support rib 330, and the outer ring bars are connected between the outer side of the circumferential support rib 330 and the air outlet end of the guide ring portion 200. In this arrangement, by providing the inner and outer ring bars 320, the distance between the outer ends of two circumferentially adjacent bars 320 away from the central connection portion 310 can be effectively controlled, that is, the size of the air outlet can be effectively controlled, so that the air outlet grille portion 300 can not only ensure the air outlet volume, but also effectively prevent foreign matter from entering the housing of the outdoor unit through the air outlet grille portion 300.

[0041] Of course, it should be noted that although a circumferential support rib 330 is provided between the connecting portion 310 and the air outlet end of the guide ring portion 200 in this embodiment, in other embodiments of the present application, the circumferential support rib 330 may not be provided between the two, or at least two circumferential support ribs 330 may be provided.

[0042] When no circumferential support ribs 330 are provided between the connecting portion 310 and the air outlet end of the guide ring portion 200, a plurality of grating bars 320 can be arranged at intervals along the circumference, and radially, the inner end 321 of each grating bar 320 is connected to the connecting portion 310, and the outer end 322 is connected to the air outlet end of the guide ring portion 200. This arrangement is more suitable for situations where the radial distance between the central connecting portion 310 and the air outlet end of the guide ring portion 200 is relatively small or the air outlet can be set to be relatively large.

[0043] When at least two circumferential support ribs 330 are provided between the connecting portion 310 and the air outlet end of the guide ring portion 200, the bars 320 may include inner, middle, and outer bars, with the inner bars connected between the connecting portion 310 and the inner sides of adjacent circumferential support ribs 330, the middle bars connected between two adjacent circumferential support ribs 330, and the outer bars connected between the air outlet end of the guide ring portion 200 and the outer sides of adjacent circumferential support ribs 330. This arrangement is more suitable for situations where the radial distance between the central connecting portion 310 and the air outlet end of the guide ring portion 200 is relatively large, or when the air outlet needs to be relatively small.

[0044] Specifically, in the present embodiment, radially, the number of bars 320 located on the outside of the circumferential support ribs 330 is greater than the number of bars 320 located on the inside thereof. More specifically, in the present embodiment, the number of bars in the inner circle is 60, while the number of bars in the outer circle is 120. By increasing the number of bars in the outer circle, the maximum distance between two adjacent bars 320 can be effectively controlled, that is, the size of each air outlet can be controlled. In other embodiments of the present application, if there are at least two circumferential support ribs 330, then along the radial direction from the connecting portion 310 to the air outlet end of the guide ring portion 200, the number of bars in each circle increases successively, that is, the number of bars in the innermost circle is the least, and the number of bars in the outermost circle is the greatest.

[0045] Specifically, in this embodiment, the multiple bars 320 all extend radially, and the multiple bars 320 in each circle are evenly arranged along the circumference. In this arrangement, the bars 320 all extend radially, so the design of the corresponding mold for the bars 320 is relatively simple. Of course, in other embodiments of the present application, the bars 320 can also extend radially and have a curvature. The evenly arranged circumferentially of the multiple bars 320 in each circle can effectively ensure that the air outlets of adjacent bars 320 are of the same size, thereby ensuring that the air outlet effect of the air outlet grille portion 300 is relatively consistent along the circumference.

[0046] Specifically, in this embodiment, the grid bar 320 can have two structural forms: Figure 5 One of the structural forms is shown in the enlarged image. Figure 10 Another structural form is shown in an enlarged manner.

[0047] Figure 5 In the embodiment, the main body 323 of the grille 320 is flat, and the angle β between the main body 323 and the normal plane of the axis of the air outlet grille portion 300 is in the range of 60° to 80°, preferably 70°. In this configuration, the shape of the grille 320 is relatively simple, so the design of the corresponding mold and the stamping process are relatively simple.

[0048] Figure 10 In the embodiment, the cross section of the main body 323 of the grille 320 is arc-shaped, and the tangent plane of the main body 323 on the air outlet side is parallel to the axis of the air outlet grille portion 300. The angle α between the tangent plane on the air inlet side of the main body 323 and the tangent plane on the air outlet side thereof is in the range of 25° to 40°. That is, the central angle corresponding to the cross section of the main body 323 is in the range of 25° to 40°, preferably 32°. In this arrangement, the grille 320 has an arc from its air inlet side to its air outlet side, and the grille 320 has a better air guiding effect.

[0049] In addition, it should be noted that although the bars 320 in this embodiment are all extended radially, in other embodiments of the present application, the bars 320 can also be extended circumferentially, for example: a plurality of radial support ribs are connected between the connecting portion 310 and the air outlet end of the guide ring portion 200, and the plurality of radial support ribs are arranged at intervals along the circumferential direction, and a plurality of bars 320 arranged at intervals along the radial direction are connected between any two adjacent radial support ribs.

[0050] This embodiment further provides an outdoor unit, including the above-mentioned outdoor unit front panel. Therefore, the outdoor unit has all the advantages of the above-mentioned outdoor unit front panel, which will not be described in detail here.

[0051] Finally, it should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include," "comprise," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0052] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
