Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioning outdoor unit. Background Art

[0002] The fan cover is one of the important parts of the air conditioner outdoor unit. It can not only protect the fan blades and prevent indoor debris from accidentally entering and damaging the fan or causing accidents, but also make the gas sucked in by the fan more concentrated, focus the blown air, improve the heat dissipation effect, and make the cooling and heating effects better.

[0003] In some air-conditioning outdoor units, due to the limitation of the external dimensions of the air-conditioning outdoor units, the distance between the fan cover and the fan is relatively close, and the fan cover has a greater blocking effect on the air output from the casing outlet to the outside of the casing after passing through the fan. Although in the prior art, some air-conditioning outdoor units choose to bulge the middle part of the fan cover away from the inside of the casing to increase the distance between the middle part of the fan cover and the fan, although this method reduces the blocking effect of the middle part of the fan cover on the air to a certain extent, the blocking effect of other parts of the fan cover on the air is still relatively large.

[0004] In other air conditioner outdoor units, the shape of the air conditioner outdoor unit fan cover is usually designed to be circular, wherein the circular air conditioner outdoor unit fan cover includes a plurality of circumferential ribs and a plurality of radial ribs, the circumferential ribs are arranged along the circumference of the air conditioner outdoor unit fan cover, and the plurality of circumferential ribs are arranged at intervals along the radial direction of the air conditioner outdoor unit fan cover; the radial ribs are arranged along the radial direction of the air conditioner outdoor unit fan cover, and the plurality of radial ribs are arranged at intervals along the circumference of the air conditioner outdoor unit fan cover. In the prior art, the radial ribs arranged along the same radial direction of the fan cover are usually one rib, that is, one radial rib is usually connected to all the circumferential ribs. This design makes the radial ribs close to the middle part of the fan cover densely arranged, while the radial ribs are sparsely arranged at the end away from the middle part of the fan cover. The dense arrangement of the radial ribs will have a greater blocking effect on the air, while the sparse arrangement of the radial ribs will easily cause the user's fingers to extend into the interior of the casing through the gaps between adjacent radial ribs, resulting in adverse consequences.

[0005] Therefore, the fan cover in the prior art still cannot well meet the requirements of the air conditioner outdoor unit. Utility Model Content

[0006] In view of the deficiencies in the related art, the present application provides an air-conditioning outdoor unit by protruding the front side of the casing with the fan cover facing away from the inside of the casing, and providing a ventilation portion on the periphery of the fan cover to reduce the wind resistance of the fan cover to the air.

[0007] The present application provides an air conditioner outdoor unit, comprising:

[0008] The casing comprises a casing air inlet and a casing air outlet, wherein the casing air inlet is arranged at the outer periphery of the casing, and the casing air outlet is arranged at the front side of the casing;

[0009] A heat exchanger is arranged inside the casing, and the heat exchanger is arranged close to the air inlet of the casing;

[0010] A fan is arranged inside the casing, the fan is located on the leeward side of the heat exchanger, and the fan is arranged close to the air outlet of the casing;

[0011] A fan cover is disposed at the air outlet of the casing and installed on the casing;

[0012] The fan housing further comprises:

[0013] The fan cover body is arranged on the front side of the casing, and the fan cover body is arranged to protrude from the front side of the casing;

[0014] A connecting portion is disposed at the outer edge of the fan cover body, and the connecting portion is disposed away from the fan cover body and toward the casing; the connecting portion is connected to the casing, and at least a portion of the connecting portion is disposed protruding from the front side of the casing;

[0015] A ventilation part, which is arranged at the connecting part and communicates with the inside of the casing;

[0016] Through the operation of the fan, at least part of the airflow in the casing is output to the outside of the casing through the ventilation part.

[0017] The technical solution is to increase the distance between the fan cover body and the fan fan by setting the fan cover body to protrude from the front side of the casing, thereby reducing the blocking effect of the fan cover body on the air; to connect the fan cover body and the casing through a connecting part so that the fan cover body is protruded from the front side of the casing and the contact area between the fan cover and the air is increased; and to increase the ventilation area of ​​the fan cover and reduce the resistance of the fan cover to the air by setting a ventilation part at the connecting part.

[0018] In some of the embodiments, the arrangement direction of the ventilation portion intersects with the circumferential direction of the fan cover body and the arrangement direction of the connection portion.

[0019] The technical solution makes the setting direction of the ventilation part intersect with the circumference of the fan cover body to avoid the ventilation part being arranged at the connecting part along the circumference of the fan body and causing the strength of the connecting part to be reduced; by making the setting direction of the ventilation part intersect with the setting direction of the connecting part, the setting size of the ventilation part can be made as large as possible under the premise that the size of the connecting part is constant, so that the fan cover has a larger ventilation volume.

[0020] In some embodiments, the direction from the side where the connecting portion is connected to the casing to the side where the connecting portion is connected to the fan cover body is the first direction; the length L1 of the connecting portion in the first direction satisfies the relationship: L1>10mm.

[0021] The technical solution increases the distance between the fan cover body and the fan by setting the length L1 of the connection part in the first direction to be greater than 10 mm, thereby reducing the resistance of the fan cover body to the air as much as possible.

[0022] In some of the embodiments, the connecting portion extends along the circumference of the fan cover body, and a plurality of ventilation portions are provided, and at least some of the ventilation portions are arranged along the extending direction of the connecting portion.

[0023] In some of the embodiments, the fan cover body includes a plurality of first ribs and a plurality of groups of second ribs, at least some of the first ribs are arranged at intervals along the radial direction of the fan cover; at least two groups of second ribs are arranged along the radial direction of the fan cover; each group of second ribs includes a plurality of second ribs, and the second ribs of the same group are arranged at intervals along the circumferential direction of the fan cover, and the two ends of the second ribs in the length direction are correspondingly connected to two adjacent first ribs.

[0024] In addition, the present application provides an air conditioner outdoor unit, comprising:

[0025] The casing comprises a casing air inlet and a casing air outlet, wherein the casing air inlet is arranged at the outer periphery of the casing, and the casing air outlet is arranged at the front side of the casing;

[0027] A fan is arranged inside the casing, the fan is located on the leeward side of the heat exchanger, and the fan is arranged close to the air outlet of the casing;

[0028] A fan cover is disposed at the air outlet of the casing and installed on the casing;

[0029] The fan housing further comprises:

[0030] A plurality of first ribs are provided, at least some of which are spaced apart in the radial direction of the fan cover, and the first ribs are provided in the circumferential direction of the fan cover;

[0031] A plurality of radial ribs are provided, at least some of which are arranged along the circumference of the fan cover; the radial ribs are arranged along the radial direction of the fan cover, and the radial ribs are connected to the first ribs;

[0032] Each radial rib includes a plurality of second ribs, and at least part of the second ribs are arranged along the radial direction of the fan cover and staggeredly distributed along the circumferential direction of the fan cover.

[0033] The technical solution designs the radial ribs as multiple second ribs arranged radially along the fan cover, so that the second ribs can be independently arranged radially along the fan cover, thereby ensuring that the safety requirement of fingers cannot be inserted into the interior of the casing through the gaps between the adjacent second ribs along the circumference of the fan cover is met. The present technical solution can also avoid the phenomenon that the radial ribs near the middle part of the fan cover are densely arranged while the radial ribs away from the middle part of the fan cover are sparsely arranged, thereby reducing the blocking effect of the second ribs on the air.

[0034] In some embodiments, the length L2 of the second rib satisfies the relationship: L2≥35mm, L2≤45mm.

[0035] In some embodiments, the distance between two second ribs arranged along the circumference of the fan cover is the rib distance D of the second ribs, and the rib distance D of the second ribs satisfies the relationship: D≥9.5mm, D≤10mm.

[0036] In some embodiments, the rib distance D of the second ribs increases gradually along the radial direction of the fan cover toward a direction away from the center of the fan cover.

[0037] In some embodiments, the distance from the side of the second rib facing the inside of the housing to the side of the second rib facing away from the inside of the housing is H, and H satisfies the relationship: H≥1.8mm, H≤2.2mm.

[0038] In the above embodiment, an air-conditioning outdoor unit is provided by making the fan cover body protrude from the front side of the casing to increase the distance between the fan cover body and the fan in the thickness direction of the casing, thereby reducing the blocking effect of the fan cover body on the air outside the casing output through the casing outlet; the fan cover body and the casing are connected by arranging a connecting part, and a ventilation part is arranged at the connecting part to increase the ventilation area of ​​the fan cover and reduce the blocking effect of the connecting part on the air.

[0039] The above-mentioned air-conditioning outdoor unit designs the radial ribs as multiple second ribs arranged radially along the fan cover, so that the second ribs can be independently arranged radially along the fan cover, thereby ensuring that the safety requirement of fingers cannot be inserted into the interior of the casing through the gaps between the adjacent second ribs along the circumference of the fan cover can be met. It can also avoid the phenomenon that the radial ribs are densely arranged at one end close to the middle part of the fan cover, while the radial ribs are sparsely arranged at one end away from the middle part of the fan cover, thereby reducing the blocking effect of the radial rib arrangement on the air.

[0057] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0058] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0059] The terms "first", "second", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0060] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0061] The air conditioner outdoor unit provided in this application may have various implementation forms. Figure 1-Figure 11 This is a specific implementation of the air conditioner outdoor unit of the present application.

[0062] like Figure 1 and Figure 2 As shown, the air-conditioning outdoor unit provided in the present application includes a casing 100, and the casing 100 is used to form the overall appearance of the air-conditioning outdoor unit. The top of the casing 100 and the bottom of the casing 100 are opposite ends, and the height direction of the casing 100 is from the top of the casing 100 to the bottom of the casing 100; the left side of the casing 100 and the right side of the casing 100 are opposite sides, and the length direction of the casing 100 is from the left side of the casing 100 to the right side of the casing 100; the front side of the casing 100 and the back side of the casing 100 are opposite sides, and the direction from the front side of the casing 100 to the back side of the casing 100 is the thickness direction of the casing 100.

[0063] like Figure 4 As shown, the housing 100 includes a housing air outlet 102 , which is disposed at the front side of the housing 100 , and the air inside the housing 100 is output to the outside through the housing air outlet 102 .

[0064] 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 .

[0065] In some embodiments, the casing air inlet 101 is disposed at the rear side of the casing 100 .

[0066] 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.

[0067] 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 .

[0068] like Figure 5 As shown, the air conditioner outdoor unit includes a heat exchanger 500, which is disposed inside the casing 100. The heat exchanger 500 is disposed close to the casing air inlet 101, and the heat exchanger 500 is used to exchange heat for the air passing therethrough.

[0069] In some embodiments, the heat exchanger 500 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 500 while keeping the internal space of the casing 100 unchanged.

[0070] like Figure 4 and Figure 5 As shown, the air conditioner outdoor unit includes a fan 300, which is disposed inside the casing 100, the fan 300 is located on the leeward side of the heat exchanger 500, and the fan 300 is disposed close to the casing air outlet 102.

[0071] Through the operation of the fan 300 , air outside the casing 100 enters the casing 100 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 500 .

[0072] In this embodiment, the fan 300 is an axial flow fan.

[0073] like Figure 5 As shown, the air conditioner outdoor unit includes a compressor 400, which is disposed inside the casing 100 and is used to drive the refrigerant to flow.

[0074] like Figure 1 and Figure 2 As 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, the gas inhaled by the fan can be 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.

[0075] The fan cover 200 includes a fan cover body, which is disposed at the front side of the housing 100 , and the fan cover body protrudes from the front side of the housing 100 .

[0076] The air inside the casing 100 is acted upon by the fan 300 and then output to the outside of the casing 100 through the casing air outlet 102. If the fan cover body is too close to the fan 300 along the thickness direction of the casing 100, it may have a greater blocking effect on the air output from the casing air outlet 102. Therefore, in the present application, the fan cover body is protruded from the front side of the casing 100 to increase the distance between the fan cover body and the fan 300 along the thickness direction of the casing 100, thereby reducing the resistance of the fan cover body to the air.

[0077] In this embodiment, the fan cover body is substantially circular.

[0078] like Figure 3 As shown, the fan cover 200 includes a connecting portion 230, which is arranged on the periphery of the fan cover body. The connecting portion 230 is arranged toward the casing 100 on a side away from the fan cover body. The connecting portion 230 is connected to the casing 100, and at least a portion of the connecting portion 230 is protruding from the front side of the casing 100.

[0079] It should be noted that the connection portion 230 is used to connect the fan cover body and the casing 100 , and the connection portion 230 is used to support the fan cover body to protrude from the front side of the casing 100 .

[0080] like Figure 7 As shown, the connection portion 230 is provided with a ventilation portion 231 , and the ventilation portion 231 is connected to the inside of the casing 100 ; through the operation of the fan 300 , at least part of the airflow in the casing 100 is output to the outside of the casing 100 through the ventilation portion 231 .

[0081] The connecting portion 230 extends along the circumference of the fan cover body to enhance the connection effect between the fan cover 200 and the housing 100 .

[0082] In this embodiment, the connecting portion 230 is ring-shaped.

[0083] A plurality of ventilation portions 231 are provided, and at least some of the ventilation portions 231 are arranged along the extending direction of the connecting portion 230 to increase the air outlet area of ​​the fan cover 200 .

[0084] A direction from the side where the connecting portion 230 is connected to the casing 100 to the side where the connecting portion 230 is connected to the fan cover body is a first direction, and the ventilation portion 231 is disposed along the first direction.

[0085] By making the arrangement direction of the ventilation portion 231 intersect with the extension direction of the connection portion 230 , the air output of the fan cover 200 can be increased while ensuring the strength of the fan cover 200 .

[0086] like Fig.11 As shown, the direction from the connection part 230 connected to the side of the casing 100 to the connection part 230 connected to the side of the fan cover body is a first direction, and the length of the connection part 230 in the first direction is L1, and L1 satisfies the relationship: L1>10mm, so as to increase the distance between the fan cover body and the fan 300, thereby reducing the resistance of the fan cover body to the air as much as possible.

[0087] If L1 is less than 10 mm, the distance between the fan cover body and the fan 300 is relatively close, and the fan cover body has a relatively large blocking effect on the air outputted from the air outlet 102 of the casing.

[0088] When L1=10 mm, the fan cover body still has a relatively large blocking effect on the air output from the air outlet 102 of the casing.

[0089] The setting direction of the ventilation part 231 intersects with the first direction, so that when the size of the connection part 230 is the same, the opening size of the ventilation part 231 can be increased as much as possible, thereby increasing the ventilation volume of the connection part 230 and reducing the air blocking effect of the connection part 230.

[0090] The arrangement direction of the ventilation portion 231 intersects with the extension direction of the connection portion 230 , so as to avoid the ventilation portion 231 being arranged along the extension direction of the connection portion 230 and reducing the overall strength of the connection portion 230 .

[0091] In some embodiments, the ventilation portion 231 is a communication port.

[0092] A contact portion 232 is disposed at one end of the connection portion 230 away from the fan cover body. The contact portion 232 is used to increase the contact area between the connection portion 230 and the housing 100 . The contact portion 232 extends along the extension direction of the connection portion 230 .

[0093] In this embodiment, the contact portion 232 is ring-shaped.

[0094] Experiments were conducted on the fan cover 200 with the ventilation part 231 provided at the connection part 230 and the fan cover 200 with no ventilation part 231 provided at the connection part 230. The experimental results show that, at the same rotation speed of the fan 300, the air volume of the fan cover 200 with the ventilation part 231 provided at the connection part 230 can be increased by 15-28m³, and the increase is close to 1%.

[0095] The above-mentioned air-conditioning outdoor unit is arranged by making the fan cover body protrude from the front side of the casing 100 to increase the distance between the fan cover body and the fan 300 in the thickness direction of the casing 100, thereby reducing the blocking effect of the fan cover body on the air outside the casing 100 output through the casing air outlet 102; by connecting the fan cover body and the casing 100 through the connecting part 230, not only can the distance between the fan cover body and the fan 300 be ensured, but also the contact area between the fan cover 200 and the air can be increased; by arranging the ventilation part 231 on the connecting part 230, the ventilation area of ​​the fan cover 200 can be increased and the blocking effect of the connecting part 230 on the air can be reduced.

[0096] like Figure 3 As shown, the fan cover body includes a first rib 210 , and the first rib 210 is arranged along the circumference of the fan cover body; the first rib 210 is arranged in plurality, and at least some of the first ribs 210 are arranged at intervals along the radial direction of the fan cover 200 .

[0097] In this embodiment, the first ribs 210 extend along the circumference of the fan cover body to form a closed curve, and a plurality of first ribs 210 are concentrically arranged.

[0098] The distance d between adjacent first ribs 210 along the radial direction of the fan cover body satisfies the relationship: d≥35mm, d≤45mm, so that the blocking effect of the fan cover body on air can be reduced as much as possible while ensuring that the fan cover body has great strength.

[0099] If d is less than 35 mm, the distance between adjacent first ribs 210 is smaller, and the first ribs 210 are arranged more densely. Although the overall strength of the fan cover body is greater, the fan cover body has a greater blocking effect on air.

[0100] If d>45mm, the distance between adjacent first ribs 210 is larger, and the first ribs 210 are arranged more sparsely. Although the fan cover body has a smaller air blocking effect, the overall strength of the fan cover body will be reduced.

[0101] The fan cover body includes radial ribs, which are arranged radially along the fan cover body. There are multiple radial ribs, and at least some of the radial ribs are arranged at intervals along the circumference of the fan cover 200. The radial ribs are interconnected with the first ribs 210 to connect several first ribs 210 to each other as a whole.

[0102] It should be noted that the distance between two radial ribs adjacent to each other along the circumferential direction of the fan cover body along the circumferential direction of the fan cover body is the rib pitch of the radial ribs.

[0103] The first ribs 210 and the radial ribs are connected to each other to form the vents 201 , and the air output from the housing air outlet 102 to the outside of the housing 100 is output to the outside of the housing 100 through the vents 201 and the ventilation portion 231 .

[0104] like Figure 6 , Figure 8 and Fig.10 As shown, the fan cover body includes a connecting member 240, which is located in the middle part of the fan cover body, and one end of the radial rib facing the center of the fan cover body is connected to the connecting member 240. The connecting member 240 and the first rib 210 are arranged concentrically.

[0105] In the prior art, one end of the radial rib in the length direction is connected to the connecting piece 240, the radial rib is extended along the same radial direction of the fan cover in a direction away from the connecting piece 240, the same radial rib is connected to all or at least part of the first rib 210, the rib pitch of the radial rib increases successively along the radial direction of the fan cover 200 in a direction away from the center of the fan cover 200, and the rib pitch of the radial rib at one end away from the connecting piece 240 is much larger than the rib pitch of the radial rib at one end close to the connecting piece 240.

[0106] Since it is easy for the user to insert his fingers into the housing 100 through the distance between adjacent radial ribs, adverse consequences may occur. One end of the radial rib in the length direction is connected to the connecting piece 240, and the radial ribs extend along the same radial direction of the fan cover in a direction away from the connecting piece 240. Therefore, the distances between adjacent radial ribs are interrelated and cannot be set independently. Therefore, in the prior art, the distance between adjacent radial ribs near one end of the connecting piece 240 is usually designed to be smaller to avoid the distance between adjacent radial ribs away from one end of the connecting piece 240 being too large. However, this design makes the radial ribs near the connecting piece 240 arranged more densely, thereby increasing the air blocking effect of the fan cover body.

[0107] Based on this, in the present application, the same radial rib is designed to include multiple second ribs 220, and at least some of the second ribs 220 are arranged along the radial direction of the fan cover body, so that the second ribs 220 located on the same radial rib can be independently arranged along the circumference of the fan cover body, so that the distance between adjacent second ribs 220 along the circumference of the fan cover body can be independently set, thereby avoiding the phenomenon that the radial ribs are densely arranged at one end close to the connecting piece 240, while the radial ribs are sparsely arranged at one end away from the middle part of the fan cover, reducing the blocking effect of the radial rib close to the connecting piece 240 on the air, and making the end of the radial rib away from the middle part of the fan cover meet the safety requirement that fingers cannot be inserted through the gap between adjacent radial ribs.

[0108] Specifically, the air conditioner outdoor unit includes a plurality of groups of second ribs 220 , and the plurality of groups of second ribs 220 are arranged along the radial direction of the fan cover 200 , and the same group of second ribs 220 are connected to two adjacent first ribs 210 and are connected to each other.

[0109] In some embodiments, two groups of second ribs 220 connected to the same first rib 210 along the radial direction of the fan cover 200 are staggered along the circumferential direction of the fan cover 200 .

[0110] Each group of second ribs 220 includes a plurality of second ribs 220 . The second ribs 220 in the same group are arranged at intervals along the circumference of the fan cover 200 . Both ends of the second ribs 220 in the length direction are correspondingly connected to two adjacent first ribs 210 .

[0111] By designing the radial ribs to be a plurality of second ribs 220 arranged radially along the fan cover 200, so that the second ribs 220 can be independently arranged radially along the fan cover 200, the safety requirement that fingers cannot be inserted into the interior of the casing 100 through the gaps between the adjacent second ribs 220 along the circumference of the fan cover 200 can be met. The phenomenon that the radial ribs near the middle part of the fan cover 200 are densely arranged while the radial ribs away from the middle part of the fan cover 200 are sparsely arranged can be avoided, thereby reducing the blocking effect of the radial ribs on the air.

[0112] like Fig. 9 As shown, the length L2 of the second rib 220 satisfies the relationship: L2≥35mm, L2≤45mm, so that the first rib 210 can be arranged under the premise of ensuring that the fan cover 200 body has greater strength and the fan cover 200 body has less blocking effect on air.

[0113] If L1<35 mm, the second ribs 220 are shorter, the distance between adjacent first ribs 210 is smaller, and the first ribs 210 are arranged more densely. Although the overall strength of the fan cover 200 body is greater, the fan cover 200 body has a greater air blocking effect.

[0114] If L1>45mm, the second ribs 220 are longer, the distance between adjacent first ribs 210 is larger, and the first ribs 210 are arranged more sparsely. Although the fan cover 200 body has a smaller air blocking effect, the overall strength of the fan cover 200 body will be reduced.

[0115] like Fig. 9 and Fig.11 As shown, the distance between two second ribs 220 arranged along the circumferential direction of the fan cover 200 along the circumferential direction of the fan cover 200 is the rib distance D of the second ribs 220, and the rib distance D of the second ribs 220 satisfies the relationship: D≥9.5mm, D≤10mm.

[0116] If D is less than 9.5 mm, the second ribs 220 are arranged more densely. Although it is difficult for fingers to extend into the interior of the housing 100 from the distance between the second ribs 220 and the strength of the fan cover 200 body is relatively high, the fan cover 200 body has a greater air blocking effect.

[0117] If D>10mm, the second ribs 220 are arranged relatively sparsely. Although the fan cover 200 body has a smaller air blocking effect, the strength of the fan cover 200 body is relatively low, and fingers can easily extend into the interior of the housing 100 through the distance between the second ribs 220 .

[0118] It should be noted that the rib spacing D of the second ribs 220 will also increase successively along the radial direction of the fan cover 200 toward the direction away from the center of the fan cover 200. However, compared with the prior art in which the same radial rib is connected to all the first ribs 210, in the present application, the rib spacing D of the second ribs 220 along the radial direction of the fan cover 200 body changes less, and the rib spacing D of the second ribs 220 away from the end of the connecting piece 240 is also relatively small.

[0119] Since one side of the second rib 220 is arranged toward the inside of the casing 100 and the other side of the second rib 220 is arranged toward the outside of the casing 100, the second rib 220 has a certain guiding effect on the air output from the casing 100 outside the casing 100 through the casing air outlet 102 to guide the air flow.

[0120] like Fig.11 As shown, the thickness direction of the second rib 220 is from the side of the second rib 220 facing the inside of the housing 100 to the side of the second rib 220 away from the inside of the housing 100. The thickness of the second rib 220 is H, and H satisfies the relationship: H≥1.8mm, H≤2.2mm, so that the second rib 220 has a better guiding effect on the air.

[0121] If H is less than 1.8 mm, the thickness of the second rib 220 is small, and the air guiding effect of the second rib 220 is weak.

[0122] If H>2.2 mm, the thickness of the second rib 220 is relatively large. Although the second rib 220 has a better air guiding effect, the second rib 220 will block the air and reduce the fluidity of the air.

[0123] It should be noted that, in some embodiments, the opposite side surfaces of two second ribs 220 adjacent to each other along the circumferential direction of the fan cover 200 are inclined along the thickness direction of the second rib 220 .

[0124] In some embodiments, the first rib 210 and the second rib 220 are integrally injection molded.

[0125] The above-mentioned air-conditioning outdoor unit designs the second ribs 220 into multiple groups along the radial direction of the fan cover 200, so that each group of second ribs 220 is connected to two adjacent first ribs 210, and each group of second ribs 220 is staggered and distributed along the circumference of the fan cover 200. This can avoid the second ribs 220 near the middle part of the fan cover 200 from being densely arranged while ensuring that the second ribs 220 meet the safety rib distance, thereby reducing the blocking effect of the second ribs 220 on the air.
