Description

Technical Field

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

[0002] In the prior art, the air outlet direction of the outdoor unit of the air conditioner is usually perpendicular to the wall and blows outwards. When the installation height of the outdoor unit is relatively low, the air outlet of the outdoor unit will blow directly on people passing by, which greatly affects the user experience. Utility Model Content

[0003] The first object of the present invention is to provide a front panel to solve the technical problem in the prior art that the air outlet of the outdoor unit of the air conditioner directly blows on people.

[0004] The front panel provided by the present invention includes a panel part, a guide part and a mesh cover part. The air inlet end of the guide part is integrally connected to the panel part, the air outlet end of the guide part is integrally connected to the mesh cover part, and the side wall of the air outlet end of the guide part is provided with an air outlet hole.

[0005] The front panel provided by the present invention can produce the following beneficial effects:

[0006] The utility model provides a front panel. When the air conditioner is working, the gas in the outdoor unit casing will enter the guide part from the air inlet end of the guide part of the front panel under the drive of the fan, flow along the guide part, and finally be blown out from the air outlet end of the guide part. Among them, part of the gas will be blown out from the air outlet holes on the side wall of the guide part, thereby reducing the airflow directly blown out from the mesh cover part, that is, it can effectively alleviate the problem of the outdoor unit air blowing directly on people.

[0007] Furthermore, the front panel provided by the present invention comprises a panel portion, a guide portion, and a mesh cover portion, all of which are integrated. For example, if the panel portion, guide portion, and mesh cover are all made of sheet metal, they can be stamped together; if they are all made of plastic, they can be integrally formed using a process such as injection molding. This not only simplifies the assembly process and improves assembly efficiency, but also effectively prevents loosening between adjacent parts, and the resulting problems of falling off and noise.

[0008] Furthermore, along the axial direction of the air guide portion, the air guide portion can accommodate at least a portion of a fan blade of the outdoor unit, and the air outlet is located between the trailing edge of the fan blade and the mesh cover portion.

[0009] Under this technical solution, it is more conducive for the part of the fan blade located in the guide part to discharge the wind from the guide part through the air outlet, thereby alleviating the problem of wind blowing directly on people.

[0010] Furthermore, there are multiple air outlet holes.

[0011] Under this technical solution, multiple air outlet holes can increase the air outlet area of ​​the side wall of the guide part, thereby increasing the air volume blown out from the side wall of the guide part and reducing the air volume blown out from the mesh cover part, thereby better alleviating the problem of the outdoor unit's air outlet blowing directly on people.

[0012] Furthermore, along the axial direction of the air guide portion, the air guide portion is provided with at least one circle of the air outlet holes, each circle includes a plurality of the air outlet holes, and the plurality of air outlet holes are evenly arranged along the circumference of the air guide portion.

[0013] Under this technical solution, the number of air outlet holes can ensure that the side wall of the guide part has sufficient air outlet area, and the air outlet holes are evenly arranged along the circumference of the guide part, so that the wind blown out along the circumference of the guide part is relatively uniform, thereby improving the air outlet uniformity of the side wall of the guide part and ensuring the overall air outlet uniformity of the outdoor unit.

[0014] Furthermore, the guide portion is circular, that is, the guide portion is a guide ring.

[0015] Under this technical solution, in the same cross section perpendicular to the axis of the air guide portion, the air outlet conditions of the air guide portion along its circumference are the same, so the air outlet uniformity of the outdoor unit along the circumference is better.

[0016] Furthermore, a connecting plate is provided in the center of the mesh cover part, the inner ends of the ribs of the mesh cover part are connected to the connecting plate, and the outer ends of the ribs are connected to the guide part; the outer surface of the connecting plate protrudes outward.

[0017] With this technical solution, when air flows out of the air outlets between the ribs of the mesh, the convex portion of the outer surface of the connecting plate guides the airflow near the center of the mesh, directing it toward the mesh's axis. As a result, the central area of ​​the entire air outlet cross-section, which is almost windless, becomes windy, and the airflow across the entire cross-section becomes more uniform. Furthermore, uniform airflow improves air delivery efficiency and reduces noise, further enhancing the user experience.

[0018] Furthermore, the outer surface of the connecting plate protrudes outward in an arc shape, a frustum shape or a cone shape.

[0019] Under this technical solution, when the outer surface of the connecting plate is in the above shape, the cross-sectional outer contour of the connecting plate gradually decreases in the direction away from the ribs, so it is beneficial for the airflow to flow toward the axis of the mesh cover.

[0020] The second purpose 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 directly blows on people.

[0021] The outdoor unit provided by the present invention includes the above-mentioned front panel, so the outdoor unit has all the advantages of the above-mentioned front panel, which will not be described in detail here.

[0022] Furthermore, the outdoor unit further includes a fan, and the fan blades of the fan are partially disposed in the air guide portion. This arrangement is more conducive to the portion of the fan blade located in the air guide portion blowing the air out from the air outlet of the mesh cover portion and the air outlet holes of the air guide portion, thereby improving the air outlet effect.

[0023] Furthermore, the fan blades are arranged to protrude toward the direction of the mesh cover, with the pressure surface facing the mesh cover. This arrangement is more conducive to the fan blades discharging the wind from the guide part through the air outlet, thereby alleviating the problem of wind blowing directly on people.

[0024] The third object of the present invention 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 directly blows on people.

[0025] The air conditioner provided by the present invention includes the above-mentioned outdoor unit, so the air conditioner has all the advantages of the above-mentioned outdoor unit, 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 a front panel, such as Figure 1 As shown, the front panel includes a panel portion 100, an air guide portion 200 and a mesh cover portion 300. The air inlet end of the air guide portion 200 is integrally connected to the panel portion 100, the air outlet end of the air guide portion 200 is integrally connected to the mesh cover portion 300, and an air outlet hole 210 is provided on the side wall of the air outlet end of the air guide portion 200.

[0037] The front panel provided in this embodiment is such that when the air conditioner is working, the gas in the outdoor unit casing will enter the air guide portion 200 from the air inlet end of the air guide portion 200 of the front panel driven by the fan, flow along the air guide portion 200, and finally be blown out from the air outlet end of the air guide portion 200, wherein part of the gas will be blown out from the air outlet holes 210 on the side wall of the air guide portion 200, thereby reducing the airflow directly blown out from the mesh cover portion 300, that is, it can effectively alleviate the problem of the outdoor unit air outlet blowing directly on people.

[0038] Moreover, the front panel provided in this embodiment, the panel part 100, the guide part 200 and the mesh cover part 300 are an integrated structure. This not only simplifies the assembly process and improves assembly efficiency, but also effectively avoids looseness between two adjacent parts and problems such as falling off and noise caused by the looseness.

[0039] More specifically, in this embodiment, the panel portion 100, the air guide portion 200, and the mesh cover portion 300 are all made of sheet metal and are integrally stamped. However, in other embodiments of the present application, the three components can also be made of other materials, for example, all three components can be made of plastic, in which case the three components can be integrally formed using a process such as injection molding.

[0040] Specifically, in this embodiment, Figure 3As shown, along the axial direction of the air guide 200, the air guide 200 can accommodate at least a portion of the fan blade 400 of the outdoor unit, and the air outlet 210 is located between the trailing edge of the fan blade 400 and the mesh cover 300. This arrangement is more conducive to the portion of the fan blade 400 located within the air guide 200 to discharge air from the air guide 200 through the air outlet 210, thereby alleviating the problem of wind blowing directly on people.

[0041] Specifically, in this embodiment, Figures 1 to 3 As shown, there are multiple air outlet holes 210. Multiple air outlet holes 210 can increase the air outlet area of ​​the side wall of the air guide portion 200, thereby increasing the air volume blown out from the side wall of the air guide portion 200 and reducing the air volume blown out from the mesh cover portion 300, thereby better alleviating the problem of the outdoor unit's air outlet directly blowing on people.

[0042] Specifically, in this embodiment, continue as Figures 1 to 3 As shown, the air guide 200 is provided with a circle of air outlet holes 210 along its axial direction, and the air outlet holes 210 in this circle of air outlet holes 210 are evenly distributed along the circumference of the air guide 200. With this arrangement, the number of air outlet holes 210 ensures that the sidewalls of the air guide 200 have sufficient air outlet area. Furthermore, the even distribution of the air outlet holes 210 along the circumference of the air guide 200 ensures that the air blown out along the circumference of the air guide 200 is relatively uniform, thereby improving the air outlet uniformity of the sidewalls of the air guide 200 and ensuring the uniformity of air outlet of the outdoor unit as a whole.

[0043] It should be noted here that the side wall of the guide portion 200 is not limited to being provided with only one circle of air outlet holes 210. For example, in other embodiments of the present application, the side wall of the guide portion 200 can also be provided with two or three circles of air outlet holes 210, each circle includes multiple air outlet holes 210, and the air outlet holes 210 in each circle are evenly arranged along the circumference of the guide portion 200.

[0044] Specifically, in this embodiment, the air guide 200 is circular, i.e., the air guide 200 is a guide ring. With this configuration, within the same cross-section perpendicular to the axis of the air guide 200, the air flow conditions at all points along the circumference of the air guide 200 are the same, thus achieving relatively good air flow uniformity along the circumference of the outdoor unit.

[0045] Specifically, in this embodiment, Figure 1As shown, a connecting plate 310 is provided in the center of the mesh cover part 300. The inner ends of the ribs 320 of the mesh cover part 300 are connected to the connecting plate 310, and the outer ends of the ribs 320 are connected to the guide part 200; the outer surface of the connecting plate 310 protrudes outward. Under this arrangement, when the airflow is blown out from the air outlet between the ribs 320 of the mesh cover part 300, the convex portion of the outer surface of the connecting plate 310 can guide the airflow near the central area of ​​the mesh cover part 300, so that the airflow flows toward the axis of the mesh cover part 300. As a result, the central area of ​​the entire air outlet cross section will change from almost no wind to windy, and the wind of the entire air outlet cross section will become more uniform. In addition, uniform air outlet is also conducive to improving air supply efficiency and noise reduction, which can further improve the user experience.

[0046] Specifically, in this embodiment, the outer surface of the connecting plate 310 has three forms: Figures 1 to 3 In the figure, the outer surface of the connecting plate 310 is planar; Figure 4 The outer surface of the connecting plate 310 is shown to be convex outward in an arc shape; Figure 5 In the embodiment of the present invention, the outer surface of the connecting plate 310 is in the shape of a frustum. Furthermore, the outer surface of the connecting plate 310 protrudes outward in the shape of a circular frustum. Of course, in other embodiments of the present application, the outer surface of the connecting plate 310 may also protrude outward in the shape of a truncated pyramid, such as an octagonal frustum. In addition, in other embodiments of the present application, the outer surface of the connecting plate 310 may also protrude outward in the shape of a cone, including a cone and a pyramid. When the outer surface of the connecting plate 310 is in the above shape, the outer profile of the cross section of the connecting plate 310 gradually decreases in the direction away from the rib 320, so it is conducive to making the airflow flow toward the axis of the mesh cover portion 300.

[0047] Figure 5 The simulated cloud diagram of the airflow outlet of the mesh cover part 300 which protrudes outward in a frustum-shaped manner from the outer surface of the connecting plate 310 shows that the central convex part of the mesh cover part 300 provided in this embodiment guides the airflow to the central area, so that there is wind in the central area of ​​the air outlet section, and the air outlet uniformity of the entire air outlet section is greatly improved.

[0048] It should be noted here that, in the present embodiment, the outer surfaces of the two forms of mesh cover parts 300 are all protruding outwards, but in other embodiments of the present application, the outer surface of the mesh cover part 300 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 play the role of draining to the center.

[0049] Specifically, in this embodiment, Figure 1As shown, the ribs 320 of the mesh cover portion 300 include a plurality of annular ribs 321 and a plurality of connecting ribs. The plurality of annular ribs 321 are coaxially arranged with the connecting plate 310 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 321, and is fixedly connected to at least one of the connecting plate 310 and the guide portion 200.

[0050] More specifically, in this embodiment, continue as Figure 1 As shown, the connecting ribs include a first connecting rib 322 and a second connecting rib 323. The two ends of the first connecting rib 322 are fixedly connected to the connecting plate 310 and the guide portion 200, respectively, and the middle is fixedly connected to all the annular ribs 321; the two ends of the second connecting rib 323 are connected to the annular rib 321 and the guide portion 200, respectively. Depending on the size of the required air outlet, the second connecting rib 323 can be fixedly connected to all the annular ribs 321, or only to some of the annular ribs 321. Figure 1 As shown in , the inner end of the second connecting rib 323 is fixedly connected to the second circle of annular ribs 321 from the inside out. If the required air outlet is relatively small, the inner end of the second connecting rib 323 can also be fixedly connected to the first circle of annular ribs 321 from the inside out. Moreover, a third connecting rib can be added between the adjacent second connecting ribs 323 and the first connecting ribs 322, so that the outer end of the third connecting rib is connected to the guide portion 200, and the inner end is connected to the annular rib 321, and is further outward than the inner end of the second connecting rib 323. Of course, if the required air outlet is larger, the inner end of the second connecting rib 323 can be set further outward, for example, so that the inner end of the second connecting rib 323 is connected to the third or fourth circle of annular ribs 321 from the inside out.

[0051] This embodiment also provides an outdoor unit, such as Figure 3 As shown, the outdoor unit includes the above-mentioned front panel, so the outdoor unit has all the advantages of the above-mentioned front panel, which will not be repeated here.

[0052] Specifically, in this embodiment, continue as Figure 3 As shown, the outdoor unit further includes a fan, and the fan blades 400 of the fan are partially disposed in the guide portion 200. Such a configuration is more conducive to the portion of the fan blades 400 located in the guide portion 200 blowing the wind out from the air outlet of the mesh cover portion 300 and the air outlet holes 210 of the guide portion 200, thereby improving the air outlet effect.

[0053] Specifically, in this embodiment, the fan blades 400 are protruding toward the pressure surface of the mesh cover 300. This arrangement is more conducive to the fan blades 400 discharging wind from the guide portion 200 through the air outlet 210, thereby alleviating the problem of wind blowing directly on people.

[0054] This embodiment also provides an air conditioner, which includes the above-mentioned outdoor unit. Therefore, the air conditioner has all the advantages of the above-mentioned outdoor unit, which will not be described in detail here.

[0055] 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.
