[0066] like Figure 2 As shown, the housing 100 includes a housing air inlet 101 , which is disposed at the outer periphery of the housing 100 , and air outside the housing 100 enters the interior of the housing 100 through the housing air inlet 101 .

[0067] In some embodiments, the casing air inlet 101 is disposed at the rear side of the casing 100 .

[0068] In other embodiments, the casing air inlet 101 is disposed on the rear side of the casing 100 and on the left side of the casing 100 and / or on the right side of the casing 100 to increase the air intake volume of the air conditioner outdoor unit.

[0069] In this embodiment, the casing air inlet 101 is opened at the rear side of the casing 100 and the right side of the casing 100 .

[0070] The casing 100 includes a casing air outlet 102 . The casing air outlet 102 is disposed at the front side of the casing 100 . The air inside the casing 100 is output to the outside through the casing air outlet 102 .

[0071] like Figure 2 As shown, the housing 100 includes a front panel 120 , which is located at the front side of the housing 100 and is used to form the front side of the housing 100 ; the housing air outlet 102 is provided on the front panel 120 .

[0072] like Figure 2 and Figure 3 As shown, the housing 100 includes a top plate 110 , which is located on the top of the housing 100 and is used to form a top surface of the housing 100 .

[0073] like Figure 3 As shown, the housing 100 includes a bottom plate 140 , which is located at the bottom of the housing 100 and is used to form the bottom surface of the housing 100 ; the bottom plate 140 and the top plate 110 are arranged opposite to each other along the height direction of the housing 100 .

[0074] like Figure 3 As shown, the housing 100 includes a side panel 130 , which is located on the left side and / or the right side of the housing 100 to form the left side surface and / or the right side surface of the housing 100 .

[0075] In this embodiment, the housing air outlet 102 is disposed on the side panel 130 located on the right side of the housing 100 .

[0076] It should be noted that the housing 100 may include a rear panel or may not include a rear panel. In this embodiment, the housing 100 does not include a rear panel to increase the air intake volume of the air conditioner outdoor unit.

[0077] like Figure 3 and Figure 4 As shown, the housing 100 includes a partition 150, which is located inside the housing 100. The partition 150 divides the cavity into a first cavity 103 and a second cavity 104. The housing air outlet 102 and the housing air inlet 101 are respectively connected to the first cavity 103.

[0078] like Figure 3 and Figure 4 As shown, the air conditioner outdoor unit includes a heat exchanger 400, which is disposed in the first cavity 103. The heat exchanger 400 is disposed close to the air inlet 101 of the casing, and the heat exchanger 400 is used to exchange heat for the air passing therethrough.

[0079] In some embodiments, the heat exchanger 400 extends from the left side of the casing 100 through the rear side of the casing 100 to the right side of the casing 100, so as to maximize the heat exchange area of ​​the heat exchanger 400 while keeping the internal space of the casing 100 unchanged.

[0080] like Figure 3 and Figure 4 As shown, the air conditioner outdoor unit includes a fan 300 , which is disposed in the first cavity 103 , the fan 300 is located on the leeward side of the heat exchanger 400 , and the fan 300 is disposed close to the air outlet 102 of the casing.

[0081] The fan 300 operates to introduce air outside the casing 100 into the first chamber 103 through the casing air inlet 101 , and is output to the outside of the casing 100 through the casing air outlet 102 after heat exchange in the heat exchanger 400 .

[0082] In this embodiment, the fan 300 is an axial flow fan 300 .

[0083] like Figure 3 and Figure 4 As shown, the air-conditioning outdoor unit includes a compressor 500 , which is disposed in the second chamber 104 , and is used to drive the refrigerant to flow.

[0084] like Figure 1 , Figure 2 and Figure 8As shown, the air conditioner outdoor unit includes a fan cover 200, which is located at the air outlet 102 of the casing; on the one hand, the fan cover 200 can protect the fan 300 to prevent debris from entering the casing 100 through the air outlet 102 of the casing and contacting the fan 300, thereby affecting the normal operation of the fan 300; on the other hand, it can make the gas inhaled by the fan more concentrated, thereby increasing the speed and pressure of the gas, and ultimately increasing the wind force output by the fan. In other words, the fan cover 200 can focus the blown air, improve the heat dissipation effect, and achieve better cooling and heating effects.

[0085] In the prior art, the fan cover 200 is usually assembled with the front panel 120 after manufacturing, and the front panel 120 is also assembled with the side panels 130, etc., and the fan cover 200 is usually a plastic part, and the front panel 120 is usually a sheet metal part. The aesthetics of the parts made of different materials assembled together is relatively poor. Based on this, in the present application, the fan cover 200 and the front panel 120 are integrally formed to reduce the assembly process of the fan cover 200 and the front panel 120, improve the assembly efficiency of the air-conditioning outdoor unit, and also increase the aesthetics of the air-conditioning outdoor unit.

[0086] Specifically, the fan cover 200 and the front panel 120 are integrally injection molded, and the integrally molded fan cover 200 and the front panel 120 are plastic parts made of polypropylene.

[0087] It should be noted that the top plate 110, the bottom plate 140 and the side plates 130 are usually still sheet metal parts to ensure the overall strength of the housing 100. For the convenience of description, the top plate 110, the bottom plate 140 and the side plates 130 are connected to form a shell, which is usually a sheet metal part.

[0088] A cavity is defined inside the shell, and the shell includes a shell opening arranged toward the front side of the housing 100. The housing air outlet 102 is arranged corresponding to the shell opening. The shell opening is connected to the cavity, and the front panel 120 is arranged at the shell opening.

[0089] In order to facilitate the connection between the front panel 120 and the housing, as shown in FIG. Figure 5 and Fig. 9 As shown, the front panel 120 is provided with a first connection portion 121 , and the first connection portion 121 is provided at the outer edge of the front panel 120 .

[0090] like Figure 5 As shown, the housing is provided with a second connection portion 131, which is located outside the housing and close to the housing opening. The second connection portion 131 is correspondingly arranged with the first connection portion 121 and connected to each other so that the front panel 120 is assembled to the housing.

[0091] In some embodiments, the first connection portion 121 is provided with a first connection hole, the second connection portion 131 is provided with a second connection hole, and the same fastener such as a bolt or a screw is provided in the first connection hole and the second connection hole to connect the front panel 120 and the housing to each other.

[0092] In this embodiment, the first connection portion 121 is disposed on the outer edge of the front panel 120 close to the left side of the casing 100 along the height direction of the casing 100 , and the second connection portion 131 is disposed on the side panel 130 located on the left side of the casing 100 .

[0093] like Fig.11 As shown, the air conditioner outdoor unit includes an air guide ring 600, which is arranged in the first cavity 103 for guiding air flow; the air guide ring 600 is arranged close to the fan 300; the air guide ring 600 is connected to the front panel 120, and the side of the air guide ring 600 away from the front panel 120 is located in the first cavity 103 and is arranged toward the fan 300.

[0094] The air guide ring 600 is usually a sheet metal part, but in this embodiment, the front panel 120 is a plastic part, so the air guide ring 600 and the front panel 120 are detachably connected.

[0095] The front panel 120 is provided with a panel, which is located on the side of the fan cover 200 facing the inside of the casing 100, and the fan cover 200 is located on the side of the panel away from the inside of the casing 100; the casing air outlet 102 is provided on the panel.

[0096] like Fig.10 and Fig.12 As shown, a mounting portion 122 is provided on one side of the panel facing the inside of the casing 100 , and the mounting portion 122 is provided at the outer edge of the casing air outlet 102 .

[0097] like Fig.12 and Fig.13 As shown, the air guide ring 600 is provided with a matching portion 601 , and the matching portion 601 is correspondingly arranged with the mounting portion 122 and matches with each other, so that the air guide ring 600 is installed on the front panel 120 .

[0098] In some embodiments, the mounting portion 122 is a hook, the matching portion 601 is a through opening, the hook passes through the through opening, and the air guide ring 600 is rotated to connect the hook with the outer edge of the through opening.

[0099] like Fig.12 and Fig.13 As shown, the air guide ring 600 is provided with an extension portion 610, which is located at one end of the air guide ring 600 facing the front side of the casing 100, and the extension portion 610 is in contact with a side of the panel facing the inside of the casing 100 to increase the contact area between the air guide ring 600 and the panel; the mating portion 601 is provided on the extension portion 610 to facilitate the connection between the air guide ring 600 and the panel.

[0100] In some embodiments, the mounting portion 122 and the matching portion 601 are respectively provided in plurality, and the plurality of mounting portions 122 and the plurality of matching portions 601 are provided in one-to-one correspondence to increase the firmness of the connection between the air guide ring 600 and the front panel 120 .

[0101] like Fig.10 As shown, the fan cover 200 includes a vent 201 , which is in communication with the first cavity 103 , and the air in the first cavity 103 is output to the outside of the casing 100 through the vent 201 from the casing air outlet 102 .

[0102] like Fig.10 As shown, the fan cover 200 includes a first rib 210, which is arranged along the longitudinal direction of the fan cover 200; the first rib 210 is usually arranged in plurality, and the plurality of first ribs 210 are arranged in the transverse direction of the fan cover 200; there is a gap between adjacent first ribs 210 along the transverse direction of the fan cover 200.

[0103] In the present embodiment, the fan cover 200 is in a square shape, the transverse direction of the fan cover 200 refers to the horizontal direction, and the longitudinal direction of the fan cover 200 refers to the vertical direction.

[0104] The size of the gap between adjacent first ribs 210 along the horizontal direction of the fan cover 200 is H1, which satisfies: H1≥7mm, H1≤10mm, so as to ensure the air outlet effect of the fan cover 200 and prevent fingers from extending into the first cavity 103 through the gap between adjacent first ribs 210.

[0105] If H1 is less than 7 mm, the gaps between adjacent first ribs 210 are too small. Although fingers cannot easily be inserted into the first cavity 103 through the gaps, the first ribs 210 have a greater blocking effect on the airflow output from the housing air outlet 102, and the air outlet effect of the fan cover 200 is poor.

[0106] If H1>10mm, the gaps between adjacent first ribs 210 are too large. Although the first ribs 210 have little blocking effect on the airflow output from the housing air outlet 102 and the fan cover 200 has a good air outlet effect, fingers can easily extend into the first cavity 103 through the gaps.

[0107] The thickness h1 of the first rib 210 satisfies the relationship: h1 ≥ 1.8 mm, h1 ≤ 2.2 mm.

[0108] If the thickness h1 of the first rib 210 is less than 1.8 mm, the strength of the first rib 210 is relatively small, and the overall strength of the fan cover 200 is relatively low.

[0109] If the thickness h1 of the first rib 210 is greater than 2.2 mm, although the first rib 210 has a relatively high strength, the first rib 210 is likely to block the airflow passing through the vent 201 , thereby reducing the air outlet effect of the fan cover 200 .

[0110] like Fig.10 As shown, the fan cover 200 includes a second rib 220, which is arranged along the transverse direction of the fan cover 200; the second rib 220 is interconnected with the first rib 210; the second rib 220 is usually arranged in plurality, and the plurality of second ribs 220 are arranged along the longitudinal direction of the fan cover 200; and there is a gap between adjacent second ribs 220 along the longitudinal direction of the fan cover 200.

[0111] It should be noted that the vent 201 is defined by the second rib 220 and the first rib 210 .

[0112] The size of the gap between adjacent second ribs 220 along the longitudinal direction of the fan cover 200 is H2, and H2 satisfies: H2 ≥ 30 mm, H2 ≤ 50 mm, so as to ensure the size of the vent 201, so that the fan cover 200 has a better air outlet effect.

[0113] If H2 is less than 30 mm, the gap between adjacent second ribs 220 is too small. When the gap size H1 between adjacent first ribs 210 remains unchanged, the size of the vent 201 is small, and the air outlet effect of the fan cover 200 is poor.

[0114] If H2>50mm, the gap between adjacent second ribs 220 is too large. When the gap size H1 between adjacent first ribs 210 remains unchanged, although the vent 201 can be made larger, the overall strength of the fan cover 200 will be reduced and the fan cover 200 will be easily damaged.

[0115] The thickness h2 of the second rib 220 satisfies the relationship: h2 ≥ 1.8 mm, h2 ≤ 2.2 mm.

[0116] If the thickness h2 of the second rib 220 is less than 1.8 mm, the strength of the second rib 220 is relatively small, and the overall strength of the fan cover 200 is relatively low.

[0117] If the thickness h2 of the second rib 220 is greater than 2.2 mm, although the second rib 220 has a relatively high strength, the second rib 220 is likely to block the airflow passing through the vent 201 , thereby reducing the air outlet effect of the fan cover 200 .

[0118] like Fig.15 As shown, the second rib 220 is tilted downward along the horizontal direction, and the second rib 220 and the horizontal direction together define a second angle β to reduce the wind resistance of the second rib 220 to the airflow passing through the vent 201 .

[0119] The second angle β satisfies: β≥0°, β<90°, so that the first rib 210 and the second rib 220 are connected to each other and jointly define the vent 201 .

[0120] When the second angle β=0°, the second rib 220 is arranged along the horizontal direction, and the second rib 220 may have a greater blocking effect on the airflow passing through the vent 201 .

[0121] When the second angle β=90°, the second rib 220 is arranged along the vertical direction, and the size of the vent 201 defined by the second rib 220 and the first rib 210 may be uneven, which affects the air outlet effect of the fan cover 200 .

[0122] It should be noted that the inclination direction of the second rib 220 is related to the rotation direction of the fan 300, which belongs to the prior art in this field and will not be described in detail.

[0123] In this embodiment, the first ribs 210 are disposed along the vertical direction, and the second ribs 220 are disposed downwardly along the length direction of the housing 100 .

[0124] like Fig.15 and Fig.16 As shown, the first rib 210 is provided with a guide portion 230, which is located at the air outlet 102 of the housing and is used to guide the air flow, thereby reducing the wind resistance of the first rib 210 to the air. The guide portion 230 is located on the side of the first rib 210 facing the inside of the housing 100, and the guide portion 230 is arranged along the length direction of the first rib 210.

[0125] It should be noted that the air guide portion 230 is the portion of the first rib 210 located at the air outlet 102 of the casing.

[0126] It should also be noted that the thickness direction of the drainage portion 230 is arranged corresponding to the thickness direction of the first rib 210 , and the thickness dimension h1 of the first rib 210 includes the thickness dimension of the drainage portion 230 .

[0127] like Fig.15 and Fig.16 As shown, a first plane is defined on one side of the fan cover 200 that faces away from the interior of the casing 100, and a projection curve of the guide portion 230 on the first plane has a horizontal dimension L along the fan cover 200; a gap between adjacent first ribs 210 along the horizontal direction of the fan cover 200 is H1, and L and H1 satisfy the relationship: L

[0128] In this embodiment, the first plane is a vertical plane extending along the length direction of the housing 100 .

[0129] ​If L>H1, the projection curve of the guide portion 230 on the first plane at least partially overlaps with the projection curve of the first rib 210 on the first plane, and the guide portion 230 easily blocks the airflow passing through the vent 201 to a greater extent, thereby reducing the air outlet effect of the fan cover 200.

[0130] If L=H1, the projection curve of the guide portion 230 on the first plane forms a closed structure with the projection curve of the gap between adjacent first ribs 210 on the first plane. The guide portion 230 easily produces a greater blocking effect on the airflow passing through the vent 201, thereby reducing the air outlet effect of the fan cover 200.

[0131] It should be noted that, since the drainage portion 230 is disposed at the housing air outlet 102, the drainage portion 230 may block the gap between adjacent first ribs 210 at the housing air outlet 102. This is common knowledge in the art and will not be elaborated herein.

[0132] like Fig.15 and Fig.16 As shown, the air guide portion 230 defines a first angle α with the vertical plane, and the first angle α satisfies: α≥0°, α≤30°, so that the air guide portion 230 can better guide the air flow.

[0133] When the thickness of the first ribs 210 is the same, if the first angle α is greater than 30°, the inclination angle of the guide portion 230 toward the adjacent first ribs 210 is larger, and the guide portion 230 is likely to cause a large obstruction to the gap between the adjacent first ribs 210, affecting the air outlet effect of the fan cover 200.

[0134] In the case where the gaps between two adjacent guide portions 230 are the same, if the first angle α>30°, the guide path of the guide portion 230 is shorter and the air guiding effect is weaker.

[0135] like Fig.14 As shown, a horizontal plane passing through the center of the casing air outlet 102 is defined as a second plane 700, and both ends of the drainage portion 230 in the length direction are correspondingly arranged along the second plane 700. The drainage portion 230 is divided into two parts with the second plane 700 as the boundary, and the two parts are inclined in opposite directions toward two adjacent first ribs 210.

[0136] A first angle α defined between the same drainage portion 230 and the vertical plane first decreases and then increases along the vertical direction.

[0137] In some embodiments, the first angle α varies uniformly from 0° to 30° along the vertical direction.

[0138] It has been verified through experiments that, under the condition that the rotation speed of the fan 300 is the same, the air volume can be increased by 1-2% by providing the guide portion 230 at the air outlet 102 of the casing compared with not providing the guide portion 230 .

[0139] The assembly steps of the above-mentioned air-conditioning outdoor unit are as follows: first, the matching part 601 and the installation part 122 are set correspondingly, and the end of the installation part 122 away from the panel passes through the matching part 601, so that the matching part 601 and the installation part 122 are initially matched, and then the air guide ring 600 is rotated so that the outer edges of the installation part 122 and the matching part 601 are constrained to each other, so that the air guide ring 600 is installed on the panel; then the first connecting part 121 and the second connecting part 131 are set correspondingly, and the first connecting part 121 and the second connecting part 131 are connected by the same fastener to realize the assembly of the front panel 120 and the outer shell.

[0140] The above-mentioned air-conditioning outdoor unit is provided with a guide portion 230 on the fan cover 200, and uses the guide portion 230 to guide the air flow, thereby reducing the wind resistance of the fan cover 200 to the air passing through the vent 201; and the fan cover 200 and the front panel 120 are integrally formed, thereby improving the assembly efficiency of the air-conditioning outdoor unit and improving the aesthetics of the air-conditioning outdoor unit.
