Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a top cover and an air conditioner. BACKGROUND

[0002] Air conditioners are increasingly applied in daily life, bringing a lot of convenience to people's life, and have various structural forms suitable for various scenes. With the intensification of market competition, the process and structure of air conditioners are continuously iteratively optimized, and various styles of indoor units are developed, and the structure of outdoor units is also optimized accordingly.

[0003] For the existing air conditioner outdoor unit, the side plate and the top cover are usually fixed and assembled on the side, and screws and the like are directly opposite the heat exchanger. In actual transportation and use, it is inevitable that the heat exchanger will be collided due to vibration and other factors, which will affect the stable operation of the outdoor unit. At the same time, there are disadvantages such as high cost, low assembly and / or ventilation and heat exchange. Therefore, if part of the side plate is replaced with an air inlet wire mesh, the fixed and assembled part of the top cover will be ineffective, and even the top cover will be loose and separated. At the same time, rainwater can easily flow down the edge of the top cover to the surface of the heat exchanger, resulting in a significant reduction in the cooling or heating effect of the air conditioner.

[0004] Therefore, it is necessary to redesign the structure of the top cover. SUMMARY

[0005] The problem solved by the present application is that the assembly of the top cover and the air inlet wire mesh in the air conditioner outdoor unit of the prior art causes rainwater to flow through the heat exchanger, resulting in poor cooling or heating effect of the air conditioner.

[0006] To solve the above problems, the present application provides a top cover arranged on an air conditioner outdoor unit, wherein the air conditioner outdoor unit comprises a heat exchanger, and heat exchanger supports and an air inlet wire mesh are arranged on the inner and outer sides of the heat exchanger, respectively. The top cover is provided with a flange that is inclined outward and extends downward on the side close to the air inlet wire mesh, and the flange is provided with a connecting structure for connecting with the air inlet wire mesh and / or the heat exchanger support. This arrangement prevents rainwater from flowing down the flange and entering the heat exchanger, preventing the air conditioner from having poor cooling or heating effect after the heat exchanger is heated, and ensuring the stable and reliable operation of the air conditioner.

[0007] Preferably, the air inlet wire mesh is arranged in close contact with the outer side of the heat exchanger, and the heat exchanger part is arranged in an arc shape; one end of the flange is provided with a first round corner, and the radius of the first round corner is the same as the radius of the air inlet wire mesh. The heat exchanger part is arranged in an arc shape, and the radius of the heat exchanger support is the same as that of the heat exchanger. This arrangement makes the appearance of the outdoor unit beautiful, facilitates air intake, and has high heat exchange efficiency with outdoor air.

[0008] Preferably, the top cover is provided with a reinforcing structure, the reinforcing structure comprising at least one reinforcing rib protruding from the top surface of the top cover and extending upward, which can greatly improve the structural strength of the top cover, thereby improving the compression strength of the air conditioner outdoor unit.

[0009] Preferably, the reinforcing structure further comprises a protruding rib arranged along the edge of the top cover, and the protruding rib is provided with a notch near the two sides of the top cover.

[0010] This arrangement can improve the mechanical strength of the top cover, and cooperate with the reinforcing rib to share the external pressure, thereby avoiding bending due to stress during transportation. In addition, the cooperation of the protruding rib and the notch allows the rainwater on the top cover to flow downward from the two sides of the top cover through the notch, thereby avoiding unnecessary heat exchange caused by a large amount of rainwater entering the heat exchanger.

[0011] Preferably, the connecting structure comprises a second assembly hole for connecting with the heat exchanger support through a screw, and a gap exists between the screw and the heat exchanger after assembly. This arrangement also ensures that the screw used for assembling the top cover does not contact the heat exchanger, thereby avoiding mechanical damage to related components caused by external forces during transportation.

[0012] Preferably, the connecting structure further comprises a first assembly hole for connecting with the air inlet wire mesh. The top cover is simultaneously connected and fixed with the wire mesh and the heat exchanger support, and the three are in mutual abutment, thereby ensuring firm and tight assembly. The structure and connection relationship of the first assembly hole are prior art, and will not be described here.

[0013] Preferably, the heat exchanger support comprises a first support body, one end of the first support body extends above the heat exchanger and abuts against the top of the heat exchanger, and an assembly plate is arranged at the end of the first support body near the heat exchanger. The assembly plate is arranged obliquely or the assembly plate is arranged vertically and a connecting plate is arranged between the assembly plate and the first support body.

[0014] This arrangement can limit the freedom of the heat exchanger support in the vertical direction, and at the same time generate a mutual supporting action between the mesh cover and / or the top cover and the heat exchanger support in the front-rear direction of the air conditioner outdoor unit, thereby improving the assembly firmness of the heat exchanger support. This arrangement is simple in structure and convenient for production and processing.

[0015] Preferably, the first support body is provided with at least one weight-reducing hole, the weight-reducing hole is an elliptical hole, and the major axis of the elliptical hole is parallel to the front-rear direction of the air conditioner outdoor unit. This arrangement is conducive to reducing the weight of the condenser support, facilitating production and transportation, and effectively improving the stress distribution on the first support body, especially in the front-rear direction of the air conditioner outdoor unit, thereby being conducive to ensuring the mechanical strength of the first support body.

[0016] Preferably, the heat exchanger support further comprises a second support body, the top end of the second support body is connected with the first support body, the first support body and the second support body are in a split structure, or the heat exchanger support is integrally stamped, so as to facilitate the processing and production of the condenser support, and meanwhile, the overall mechanical strength of the condenser support can be effectively ensured.

[0017] Compared with the prior art, the top cover has the following beneficial effects: 1) the inclined flange can effectively prevent rainwater from entering the heat exchanger when the rainwater flows downward, prevent the air conditioner from having poor refrigeration or heating effect due to the heat exchange of the rainwater, and ensure the stable and reliable operation of the air conditioner; 2) one end of the flange is provided in a large round corner, and the structure is simple and the appearance is beautiful; 3) the gap between the screw and the heat exchanger after assembly of the top cover can avoid mechanical damage of related components caused by external force during transportation.

DETAILED DESCRIPTION

[0029] The inventive concepts of the present disclosure will be described below using terms that a person of ordinary skill in the art commonly employs to convey the substance of their work to others of ordinary skill in the art. However, these inventive concepts can be embodied in many different forms, and thus should not be considered limited to the embodiments described herein.

[0030] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The directional terms in the present application are based on the normal placement or normal installation state of the air conditioner outdoor unit.

[0031] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] The existing air conditioner outdoor unit usually has side wall plates and a top plate arranged on the periphery, which are fixed by screws and the like. At this time, the screws are directly opposite the heat exchanger 5, and are prone to knocking against the heat exchanger 5 during transportation or external impact, which affects the stable operation of the outdoor unit, and even causes mechanical damage to the related components of the air conditioner outdoor unit. After replacing part of the side plates 7 with air inlet wire meshes 3, the assembly and fastening of the conventional top plate are greatly compromised, and the top plate may become loose or detached during transportation or use. At the same time, rainwater may flow down along the edge of the top plate to the surface of the heat exchanger 5 and cause poor cooling or heating effect of the air conditioner.

[0033] To solve the problem of poor cooling or heating effect of the air conditioner caused by rainwater flowing through the heat exchanger after the top cover 1 and the air inlet wire mesh 3 are assembled in the air conditioner outdoor unit of the prior art, the present embodiment proposes a top cover 1 as shown in FIG. 1.

This arrangement prevents rainwater from flowing down along the flange 11 from entering the heat exchanger 5, ensuring stable and reliable operation of the air conditioner. The heat exchanger 5 is arranged in an arc shape, and the curvature of the heat exchanger support 2 is the same as that of the heat exchanger 5. This arrangement makes the appearance of the outdoor unit beautiful, facilitates air intake, and improves the heat exchange efficiency with outdoor air.

[0034] The air conditioner outdoor unit includes a base 8, the upper side of the base 8 is provided with an air inlet iron mesh 3, a mesh cover 6 and a side plate 7, one side of the air inlet iron mesh 3 is connected to the mesh cover 6, a part of the air inlet iron mesh 3 is arranged in an arc shape, the other side of the air inlet iron mesh 3 is connected to the side plate 7, the air inlet iron mesh 3, the mesh cover 6 and the side plate 7 form a cavity for accommodating the heat exchanger 5, the heat exchanger 5 is arranged in an arc shape and has the same curvature as the air inlet iron mesh 3. The structure of the heat exchanger support 2 is the prior art and will not be described here. Preferably, the bottom of the heat exchanger support 2 is fixedly connected to the base 8, and the assembly structure is the prior art and will not be described here.

[0035] Preferably, the air conditioner outdoor unit further comprises a fan support 4, which is the same as the conventional fan support and can fix and support the fan, and the assembly of the fan support 4 with the fan is the same as the prior art and will not be described here. The bottom end of the fan support 4 is fixedly connected to the base 8 by screws or other fasteners, and the top end of the fan support 4 is clamped to the top of the heat exchanger 5, which not only limits the freedom of the heat exchanger 5 in the vertical direction, but also supports the top of the heat exchanger 5 in the horizontal direction, preventing the heat exchanger 5 from falling during transportation of the air conditioner outdoor unit. The position of the fan support 4 is related to the assembly position of the fan, which is usually near the middle of the base 8 in the prior art, which corresponds to the middle position of the heat exchanger 5, so that the top end of the fan support 4 can be clamped to the middle position of the top end of the heat exchanger 5, thereby ensuring the support of the heat exchanger 5 in the horizontal direction without changing the assembly position of the conventional fan support 4.

[0036] One end of the flange 11 is provided with a first round corner 12, the radian of the first round corner 12 is same as the radian of the air inlet wire mesh 3.

Preferably, the reinforcing structure 14 further includes a convex rib 142 arranged along the edge of the top cover 1, and notches 143 are arranged on both sides of the convex rib 142. The setting can further improve the mechanical strength of the top cover 1, and at the same time, cooperate with the reinforcing rib 141 to share the pressure applied by the outside, to avoid bending during transportation. In addition, the convex rib 142 cooperates with the notches 143 to make the rainwater of the top cover 1 flow down from both sides of the top cover 1 through the notches 143, avoiding unnecessary heat exchange caused by a large amount of rainwater entering the heat exchanger 5.

[0038] As an example of the present application, the connecting structure 13 includes a first assembly hole 131 and a second assembly hole 132, which are respectively used for fixed connection with the fan support 4 and the heat exchanger support 2 through screws, and there is a gap between the screws and the heat exchanger 5 after assembly. The connecting structure 13 further includes a third assembly hole 133 for connecting with the air inlet wire mesh 3. The structures of the first assembly hole 131 and the second assembly hole 132 can be same or different, and the structure of the third assembly hole 133 is the prior art, which is not described here.

[0039] Specifically, the heat exchanger support 2 comprises a first frame body 21 and a second frame body 22, the bottom end of the second frame body 22 is fixedly connected with the base 8, the top end of the second frame body 22 is connected with the first frame body 21, one end of the first frame body 21 is connected with the mesh cover 6 and / or the flange 11 of the air conditioner outdoor unit, the other end of the first frame body 21 extends to the upper side of the heat exchanger support 2 and abuts against the top of the heat exchanger support 2, so that not only the freedom of the heat exchanger support 2 in the vertical direction can be limited, but also a mutual supporting action between the mesh cover 6 and / or the top cover 1 and the heat exchanger support 2 in the front-rear direction of the air conditioner outdoor unit can be simultaneously generated, and the source of the supporting force is located in the air conditioner outdoor unit between the mesh cover 6, the top cover 1, the base 8 and the heat exchanger support 2, which can effectively fix and support the heat exchanger support 2 and the outdoor unit shell assembly, improve the assembly reliability of the heat exchanger support 2, and effectively avoid the heat exchanger support 2 from tilting, deforming, and fixing failure during actual transportation, installation and use of the air conditioner outdoor unit.

[0040] For the connection of the first frame body 21 with the shell assembly and the heat exchanger support 2, the front end of the first frame body 21 is provided with a front flange 211, the front flange 211 is attached to the inner side of the mesh cover 6 and / or the inner side of the flange 11 of the top cover 1, and the front flange 211 is fixedly connected with the mesh cover 6 and / or the flange 11 of the top cover 1 through screws or other fasteners; the rear end of the first frame body 21 is provided with a wing plate 213, the wing plate 213 abuts against the top end of the heat exchanger support 2, and the rear end of the first side edge 212 abuts against the front side of the heat exchanger support 2, so that the first frame body 21 can generate a clamping force on the heat exchanger support 2, which is beneficial to improve the assembly reliability of the heat exchanger support 2 on the one hand, and the first frame body 21 can simultaneously support the mesh cover 6 and / or the top cover 1 and the heat exchanger support 2, which can effectively avoid the heat exchanger support 2 from tilting and assembly failure.

By providing a specific lightening hole 214, on the one hand, the weight of the heat exchanger support 2 can be reduced, which is convenient for production and transportation, and on the other hand, the stress distribution on the first frame body 21, especially in the front-rear direction of the air conditioner outdoor unit, can be effectively improved, which is beneficial to ensure the mechanical strength of the first frame body 21.

[0042] The first frame body 21 is provided with an assembling plate 216 at one end close to the wing plate 213, and the assembling plate 216 is provided with a connecting hole 217 for fixed connection with the second assembling hole 132 of the top cover 1.

[0044] As an example of the present application, the second frame body 22 is arranged vertically, and a bottom flange 222 is arranged at the bottom end of the second frame body 22.

The folded edge 223 and the assembling inclined edge are fixedly connected by screws or other fasteners, so as to realize the connection between the second frame body 22 and the base 8. At the same time, the folded edge 223 and the assembling inclined edge are both inclined upward with respect to the horizontal plane, which avoids possible space interference, so that the fastener can be easily assembled by the assembly worker at the front side of the external machine during assembly of the second frame body 22 and the base 8, thereby reducing the assembly operation difficulty.

[0045] The bottom flange 222 is provided with a clamping hole 224, and the corresponding position of the base 8 is provided with a protrusion. The protrusion and the clamping hole 224 are clamped and assembled. This arrangement can position and limit the assembly of the second frame body 22, and on the other hand, it is beneficial to improve the connection reliability of the second frame body 22 and the base 8, and further improve the assembly reliability of the heat exchanger support 2 as a whole. The second frame body 22 is connected to the upper end surface of the base 8. Preferably, the second frame body 22 is provided with a second side edge 221 at both sides, so as to further improve the connection reliability of the bottom end of the second frame body 22.

[0046] For the connection of the first frame body 21 and the second frame body 22, two sides of the second frame body 22 are provided with second side edges 221, two sides of the first frame body 21 are provided with first side edges 212, and the top ends of the second side edges 221 are fixedly connected with the first side edges 212 by means of screws or other fasteners. In the present application, the first frame body 21 is preferably horizontally arranged, so that the second frame body 22 and the first frame body 21 form a structure similar to a T shape, so that the heat exchanger support 2 can form force supporting points with the mesh cover 6 and / or the top cover 1 and the base 8 of the outdoor unit and the heat exchanger support 2, respectively, and the assembly firmness of the heat exchanger support 2 to the heat exchanger support 2 is improved.
