Description

Technical Field

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

[0002] In the prior art, for air conditioner outdoor units, in order to increase the connection area of ​​the ribs of the air outlet grille and facilitate the installation of the ribs, a connecting plate is usually provided in the central portion of the air outlet grille so that the inner ends of the ribs are connected to the periphery of the connecting plate. Figure 1 As shown, it is precisely because of the setting of the connecting plate that no air comes out of the central part of the air outlet mesh cover, resulting in the air blown out by the air outlet mesh cover being larger around the edges and smaller in the middle, which is very uneven. Utility Model Content

[0003] The first object of the present invention is to provide an air outlet mesh cover to solve the technical problem in the prior art that the air outlet of an outdoor unit of an air conditioner is large around but very small in the middle, which is very uneven.

[0004] The air outlet mesh cover provided by the present invention includes an inner connecting part located in the center, an outer connecting part located in the outer ring, and a rib part fixedly connected between the two. The outer surface of the inner connecting part is non-planar, and at least partially protrudes outward from the rib part and can divert air in the axial direction of the air outlet mesh cover.

[0005] The air outlet mesh cover provided by the utility model can produce the following beneficial effects:

[0006] The air outlet grille provided by this utility model, when air is blown out from the air outlet between the ribs of its ribbed section, the convex portion of the outer surface of its inner connecting portion can guide the airflow near the central area of ​​the air outlet grille, causing the airflow to flow in the direction of the axis of the air outlet grille. As a result, the central area of ​​the entire air outlet cross-section will change from almost no wind to windy, and the wind will become more uniform across the entire air outlet cross-section, effectively alleviating the situation where the wind is strong at the periphery and weak in the center. In addition, the uniform air outlet is conducive to improving air supply efficiency and reducing noise, thereby further enhancing the user experience.

[0007] Furthermore, the outer surface of the inner connecting portion protrudes outward in an arc shape, a frustum shape or a cone shape.

[0008] Under this technical solution, the outer contour of the cross section of the inner connecting portion gradually decreases in the direction away from the rib portion, so it is beneficial for the air flow to flow toward the axis of the air outlet grille.

[0009] Furthermore, the inner connecting portion is a connecting plate, and / or the outer connecting portion is a connecting ring.

[0010] Under this technical solution, the inner side of the convex part of the inner connecting part is hollow to form a cavity. With this arrangement, the weight of the air outlet mesh cover is relatively light, which is conducive to the lightweighting of the air conditioner outdoor unit.

[0011] Furthermore, the rib portion includes a plurality of annular ribs and a plurality of connecting ribs, and the plurality of annular ribs are coaxially arranged with the inner connecting portion and radially spaced apart; the plurality of connecting ribs are radially extended, and each of the connecting ribs is fixedly connected to at least two of the annular ribs, and is fixedly connected to at least one of the inner connecting portion and the outer connecting portion.

[0012] Furthermore, the air outlet mesh cover, the guide ring and the front panel of the air conditioner outdoor unit are an integrated structure. The air outlet mesh cover is integrally connected to the air outlet end of the guide ring, and the air inlet end of the guide ring is integrally connected to the front panel.

[0013] Under this technical solution, the air outlet grille, deflector, and front panel can all be made of sheet metal and stamped together, or they can all be made of plastic and molded as a single piece using a process like injection molding. This integrated structure not only simplifies assembly and improves efficiency, but also effectively prevents loosening and the resulting problems of falling off and noise.

[0014] Optionally, the air outlet mesh cover and the guide ring of the air conditioner outdoor unit are an integrated structure, the air outlet mesh cover is integrally connected to the air outlet end of the guide ring, and the air inlet end of the guide ring is fixedly connected to the front panel of the outdoor unit.

[0015] This technical solution can also reduce the assembly process to a certain extent and improve assembly efficiency. Moreover, there will be no looseness between the air outlet grille and the guide ring, which will not cause problems such as falling off or noise.

[0016] Furthermore, the air outlet end of the guide ring is provided with a plurality of air outlet holes along the circumferential direction.

[0017] Under this technical solution, by setting up air outlet holes, part of the wind can be blown out from the side of the guide ring, thereby alleviating the problem of wind blowing directly on people.

[0018] Furthermore, along the axial direction of the guide ring, the guide ring can accommodate a portion of the fan blade of the outdoor unit, and the air outlet is located between the trailing edge of the fan blade and the air outlet mesh cover. This arrangement is more conducive to the portion of the fan blade located within the guide ring to blow out the gas within the guide ring, thereby improving the air outlet effect.

[0019] The second object of the present invention is to provide an outdoor unit to solve the technical problem in the prior art that the air outlet of the outdoor unit of the air conditioner is large around and very small in the middle, which is very uneven.

[0020] The outdoor unit provided by the present invention includes the above-mentioned air outlet mesh cover and has all the advantages of the above-mentioned air outlet mesh cover, which will not be described in detail here.

[0021] The third object of the present utility model is to provide an air conditioner to solve the technical problem in the prior art that the air outlet of the outdoor unit of the air conditioner is large around and very small in the middle, which is very uneven.

[0022] The air conditioner provided by the present invention includes the above-mentioned outdoor unit, so it also has all the advantages of the above-mentioned air outlet mesh cover, 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] like Figure 1 As shown, in the prior art, the central part of the air outlet mesh cover does not blow air, and the air blown out by the air outlet mesh cover is large around and small in the middle, which is very uneven. In order to solve this problem, this embodiment provides an air outlet mesh cover 100, as shown in FIG. Figures 2 to 4 As shown, the air outlet mesh cover 100 includes an inner connecting portion 110 located in the center, an outer connecting portion 120 located in the outer ring, and a rib portion 130 fixedly connected between the two. The outer surface of the inner connecting portion 110 is non-planar, and at least partially protrudes outward from the rib portion 130 and can divert air in the axial direction of the air outlet mesh cover 100.

[0037] When air flows out of the air outlet between the ribs of the rib portion 130 of the air outlet grille 100 provided in this embodiment, the convex portion of the outer surface of the inner connecting portion 110 guides the airflow near the central area of ​​the air outlet grille 100, directing it toward the axis of the air outlet grille 100. As a result, the central area of ​​the entire air outlet cross-section changes from being almost windless to having wind, and the wind across the entire air outlet cross-section becomes more uniform, effectively alleviating the situation where strong winds are blowing around and weak winds are blowing in the center. Furthermore, uniform airflow improves air supply efficiency and reduces noise, further enhancing the user experience.

[0038] Specifically, in this embodiment, the outer surface of the inner connecting portion 110 may be convex outwards in an arc shape, such as Figure 2 and Figure 3 It can also be in the shape of a truncated cone. Preferably, the outer surface of the inner connecting portion 110 can protrude outward in the shape of a truncated cone, such as Figure 4 As shown, of course, in other embodiments of the present application, the outer surface of the inner connecting portion 110 may also protrude outward in a truncated pyramid shape, such as an octagonal truncated pyramid shape. Furthermore, in other embodiments of the present application, the outer surface of the inner connecting portion 110 may also protrude outward in a conical shape, including a cone shape and a pyramid shape. When the outer surface of the inner connecting portion 110 is in the above shape, the cross-sectional outer profile of the inner connecting portion 110 gradually decreases in the direction away from the rib portion 130, thereby facilitating the airflow to flow toward the axis of the air outlet grille 100.

[0039] Figure 4The outer surface of the inner connection part 110 protrudes outwards in a truncated cone shape, and the air flow simulation cloud diagram of the air outlet mesh cover 100 is combined with Figure 1 It can be clearly seen from the figure that the central convex part of the air outlet mesh cover 100 provided in this embodiment guides the airflow to the central area, so that the central area of ​​the air outlet section also has wind, and the air outlet uniformity of the entire air outlet section is greatly improved.

[0040] It should be noted here that, in the present embodiment, the outer surfaces of both forms of air outlet mesh covers 100 are all protruding outwards, but in other embodiments of the present application, the outer surface of the air outlet mesh cover 100 may be only partially protruding outwards, and the remaining part may be a vertical plane or concave inwards, as long as the protruding part can serve to guide air to the center.

[0041] Specifically, in this embodiment, the inner connecting portion 110 is a connecting plate, i.e., the inner side of the convex portion is hollow, forming a cavity. This arrangement makes the air outlet grille 100 relatively lightweight, contributing to the lightweight design of the air conditioner outdoor unit. However, in other embodiments of the present application, the configuration of the inner connecting portion 110 is not limited to this. For example, the inner connecting portion 110 may also be a solid structure, as long as its outer surface is convex and can function to guide air toward the center.

[0042] Specifically, in this embodiment, the outer connection portion 120 is a connecting ring, the outer end of the rib portion 130 is connected to the connecting ring, and the entire air outlet grille 100 is connected to the guide ring 200 through the connecting ring.

[0043] Specifically, in this embodiment, Figure 2 As shown, the rib portion 130 includes a plurality of annular ribs 131 and a plurality of connecting ribs. The plurality of annular ribs 131 are coaxially arranged with the inner connecting portion 110 and are radially spaced apart. The plurality of connecting ribs are radially extended, and each connecting rib is fixedly connected to at least two annular ribs 131 and is fixedly connected to at least one of the inner connecting portion 110 and the outer connecting portion 120.

[0044] More specifically, in this embodiment, continue as Figure 2 As shown, the connecting ribs include a first connecting rib 132 and a second connecting rib 133. The two ends of the first connecting rib 132 are fixedly connected to the inner connecting portion 110 and the outer connecting portion 120, respectively, and the middle is fixedly connected to all the annular ribs 131; the two ends of the second connecting rib 133 are connected to the annular rib 131 and the outer connecting portion 120, respectively. Depending on the size of the required air outlet, the second connecting rib 133 can be fixedly connected to all the annular ribs 131, or only to some of the annular ribs 131, as shown in FIG. Figure 2As shown in , the inner end of the second connecting rib 133 is fixedly connected to the second circle of annular ribs 131 from the inside out. If the required air outlet is relatively small, the inner end of the second connecting rib 133 can also be fixedly connected to the first circle of annular ribs 131 from the inside out. Moreover, a third connecting rib can be added between the adjacent second connecting ribs 133 and the first connecting ribs 132, so that the outer end of the third connecting rib is connected to the outer connecting portion 120, and the inner end is connected to the annular rib 131, and is further outward than the inner end of the second connecting rib 133. Of course, if the required air outlet is larger, the inner end of the second connecting rib 133 can be set further outward, for example, the inner end of the second connecting rib 133 can be connected to the third or fourth circle of annular ribs 131 from the inside out.

[0045] Specifically, in this embodiment, the air outlet mesh cover 100, the guide ring 200 and the front panel 300 of the air conditioner outdoor unit are an integrated structure. The air outlet mesh cover 100 is integrally connected to the air outlet end of the guide ring 200, and the air inlet end of the guide ring 200 is integrally connected to the front panel 300. More specifically, in this embodiment, the air outlet mesh cover 100, the guide ring 200 and the front panel 300 are all made of sheet metal, and the three are formed by integrated stamping. However, in other embodiments of the present application, the three can also be made of other materials. For example, the three are made of plastic. In this case, the three can be integrally formed through processes such as injection molding. The three are an integrated structure, which can not only simplify the assembly process and improve assembly efficiency, but also effectively avoid problems such as loosening and falling off and noise caused by loosening.

[0046] It should also be noted that in other embodiments of the present application, only the air outlet grille 100 and the air guide ring 200 of the air conditioner outdoor unit may be an integrated structure, with the air outlet grille 100 and the air guide ring 200 being integrally connected at their outlet ends, while the air inlet end of the air guide ring 200 is fixedly connected to the front panel 300 of the outdoor unit, for example, by screws, snaps, or welding. This arrangement can also reduce assembly processes to a certain extent and improve assembly efficiency. Moreover, there will be no looseness between the air outlet grille 100 and the air guide ring 200, thereby preventing problems such as falling off or noise.

[0047] Specifically, in this embodiment, Figure 6 As shown, the air outlet end of the guide ring 200 is provided with a plurality of air outlet holes 210 along the circumference. Furthermore, the plurality of air outlet holes 210 are evenly spaced along the circumference. By providing the air outlet holes 210, some air can be blown out from the sides of the guide ring 200, thereby alleviating the problem of wind blowing directly on people.

[0048] Specifically, in this embodiment, continue as Figure 6As shown, along the axial direction of the guide ring 200, the guide ring 200 can accommodate a portion of the fan blade 400 of the outdoor unit fan, and the air outlet 210 is located between the trailing edge of the fan blade 400 and the air outlet mesh cover 100. This arrangement is more conducive to the portion of the fan blade 400 located inside the guide ring 200 blowing out the gas inside the guide ring 200, thereby improving the air outlet effect.

[0049] Furthermore, the pressure surface of the fan blade 400 toward the air outlet mesh cover 100 can protrude outward, that is, protrude toward the direction where the air outlet mesh cover 100 is located. This is more conducive to the fan blade 400 blowing the gas out of the air outlet hole 210 of the guide ring 200, thereby alleviating the problem of the air blowing directly on people.

[0050] This embodiment also provides an outdoor unit, Figure 5 and Figure 6 Two forms of the outdoor unit are shown respectively, and both forms of the outdoor unit include the above-mentioned air outlet mesh cover 100, so both have all the advantages of the above-mentioned air outlet mesh cover 100, which will not be repeated here.

[0051] This embodiment also provides an air conditioner, which includes the above-mentioned outdoor unit and thus has all the advantages of the above-mentioned air outlet grille 100, which will not be described in detail here.
