[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Reference below Figure 1-Figure 7 An air conditioner outdoor unit 100 and an air conditioner according to an embodiment of the present invention are described.

[0034] like Figure 1 and Figure 2As shown, according to the first aspect of the embodiment of the present application, the air-conditioning outdoor unit 100 includes: a shell 10 and a handle 20. The shell 10 is provided with a handle installation opening, and the handle 20 is arranged on the handle installation opening to block and shield the handle installation opening. The handle 20 is provided with at least a hand-grip portion. When carrying the air-conditioning outdoor unit 100, the hand-grip portion can be grasped to reduce the difficulty of carrying, improve the carrying efficiency, reduce the difficulty of installation work, and improve the safety during the installation process.

[0035] However, it is understandable that the air-conditioning outdoor unit 100 is provided with components such as a compressor and a heat exchanger, which are relatively heavy, and the handle 20 is generally constructed as a plastic part. During transportation and installation, the plastic part may be deformed, resulting in a larger gap between the handle mounting opening and the handle 20. In addition, when the air-conditioning outdoor unit 100 is placed outdoors, there is a certain probability that rain will directly hit the gap, or water will flow through the gap into the accommodation space of the indoor unit, causing water to enter the air-conditioning outdoor unit 100, reducing the working stability and safety of the air-conditioning outdoor unit 100, and even causing damage to the air-conditioning outdoor unit 100.

[0036] Based on this, the present application further arranges an installation sink 11 on the outer shell 10, that is, the outer shell 10 has an installation sink 11, and the installation sink 11 is located on the peripheral side of the handle mounting port, and then a flange plate 22 is arranged on the handle 20, that is, the handle 20 includes: a main body plate 21 and a flange plate 22 arranged on the main body plate 21, and the flange plate 22 has a height difference with the main body plate 21 in the installation direction, so that the flange plate 22 overlaps the outer surface of the outer shell 10, and the main body plate 21 overlaps the installation sink 11.

[0037] Specifically, if Figure 3 and Figure 7 As shown, there is a height difference between the flange plate 22 and the main body plate 21 to define a step surface, and the step surface includes: a first surface (the surface of the flange plate 22 facing the shell), a second surface (the surface of the main body plate 21 facing the shell) and a first connecting surface between the first surface and the second surface. The first surface is overlapped on the outer surface of the outer shell 10, and the main body plate 21 is overlapped on the mounting sink 11, so that the first surface is in contact and sealed with the outer surface, and the main body plate 21 is in contact and sealed with the mounting sink 11, so as to achieve a surface-to-surface contact seal between the handle 20 and the handle mounting port, thereby improving the sealing effect between the handle 20 and the handle mounting port, avoiding direct rainwater, and reducing the probability of rainwater pouring into the accommodating space, thereby improving the working stability and safety of the air-conditioning outdoor unit 100.

[0038] Furthermore, the mounting platform 11 has a sunken surface that is sunken compared to the outer surface of the outer shell 10, and a second connecting surface is provided between the sunken surface and the outer surface of the outer shell 10. The first connecting surface and the second connecting surface can also be constructed as a surface contact seal, through at least three surface contact seals, and one of the surface contact seals is in a different direction from the planes of the other two surface contact seals, so as to form a "Z"-shaped labyrinth sealing structure, which effectively improves the seal between the handle 20 and the outer shell 10, and by providing the flange plate 22, the structural strength of the handle 20 can also be improved, and the deformation of the handle 20 constructed as a plastic part during installation and transportation can be reduced, so as to ensure a stable and reliable connection between the wrench and the outer shell 10.

[0039] According to the air-conditioning outdoor unit 100 of the embodiment of the present application, by setting a mounting sink 11 on the outer shell 10 and setting a flange plate 22 on the handle 20, on the one hand, the setting of the mounting sink 11 and the flange plate 22 can increase the number of sealing surfaces between the outer shell 10 and the handle 20, and the flange plate 22 can block the gap between the handle 20 and the handle mounting port, so as to reduce the probability of water and foreign matter entering the air-conditioning outdoor unit 100, and improve the working stability, reliability and safety of the air-conditioning outdoor unit 100; on the other hand, the flange plate 22 can improve the structural strength of the handle 20, and improve the deformation of the handle 20 during the installation and transportation of the air-conditioning outdoor unit 100, so as to ensure that the flange plate 22 blocks the gap between the handle 20 and the handle mounting port, and improve the waterproof effect.

[0040] It should be noted that the air conditioner outdoor unit 100 can prevent water in the outdoor environment from dripping onto the internal components of the air conditioner outdoor unit 100, which may be components such as an electronic control device and a compressor. The air conditioner outdoor unit 100 includes a housing 10 and a handle 20 mounted on the housing 10; wherein the housing 10 includes a front panel and a side panel connected to the front panel and extending backward (see Figure 1 , which may include a left side panel and a right side panel), the side panel is provided with a handle mounting opening, the handle 20 can be installed on the handle mounting opening, and the side panel and the front panel can also be constructed as a detachable structure, one of the corresponding side panel and the front panel is provided with a buckle plate, and the other is provided with a buckle hole buckled with the buckle plate, the handle 20 is installed on the handle mounting opening, and a shielding portion can also be provided on the handle 20, the shielding portion is used to shield the buckle hole, so as to achieve effective shielding of the gap on the shell 10 through the shielding portion and the flange plate 22, thereby improving the sealing effect of the shell 10.

[0041] See also Figure 7 As shown, according to some embodiments of the present application, the width dimension W1 of the flange plate 22 is 3 mm to 5 mm.

[0042] Exemplarily, the width dimension of the flange plate 22 can be 3mm, 4mm or 5mm, etc., and a first connecting plate is formed between the flange plate 22 and the main plate 21. The flange plate 22 defines a first surface, the main plate 21 defines a second surface, and the first connecting plate defines a first connecting surface to realize three contact sealing surfaces, effectively improving the sealing effect, and at the same time making the thickness dimension of the flange plate 22 not less than 3mm and not greater than 5mm, so that the protruding length of the flange plate 22 compared with the first connecting plate is more reasonable, avoiding the width dimension being too small, resulting in the inability to effectively block the gap between the handle 20 and the handle mounting port, and ensuring a certain displacement margin to ensure that the handle 20 has a small movement during transportation and installation, and also ensuring the blocking effect of the flange plate 22 on the gap, avoiding the width dimension being too large, reducing material costs, and also avoiding the end of the flange plate 22 away from the first connecting plate from warping, ensuring the stable contact between the first surface and the outer surface of the shell 10 to improve the sealing effect.

[0043] exist Figure 7 In the illustrated embodiment, in some embodiments, the thickness C of the flange plate 22 is 1.5 mm to 2.5 mm.

[0044] Exemplarily, the thickness of the flange plate 22 can be 1.5 mm, 2 mm, 2.5 mm, etc., so that the thickness of the flange plate 22 is more reasonable, ensuring that the size of the flange plate 22 protruding from the outer surface of the outer shell 10 is more reasonable, avoiding the thickness of the flange plate 22 being too small, resulting in the flange plate 22 The structural strength is too low, the structural reinforcement effect of the handle 20 is limited, and the flange plate 22 breaks during transportation and installation, which leads to sealing failure. It is also possible to avoid the thickness of the flange plate 22 being too large to ensure that the thickness of the flange plate 22 protruding from the outer surface of the outer shell 10 is more reasonable, so as to improve the convenience of assembly, avoid the flange plate 22 from interfering with the surrounding environmental features such as the wall during the assembly process, and at the same time improve the aesthetics of the air-conditioning outdoor unit 100.

[0045] See also Figure 3 and Figure 7 In the embodiment shown, according to some embodiments of the present application, the length L1 of the relative area between the flange plate 22 and the outer surface of the shell 10, and the length L2 of the relative area between the side of the main body plate 21 and the side of the mounting sink 11 satisfy L1+L2≥2.5mm.

[0046] Specifically, the contact length between the first surface and the outer surface of the shell 10 is L1, and the contact length between the first connecting surface and the second connecting surface is L2, L1+L2≥2.5mm, so as to extend the flow distance of external rainwater into the accommodating space. By setting a longer water flow distance, the surface tension of water is reduced, and the penetration of rainwater is effectively delayed and avoided, thereby improving the waterproof effect, especially preventing rainwater from entering the electronic control module, so as to avoid short circuit in the electronic control module and improve safety and reliability.

[0047] It should be noted that the sum of L1 and L2 can be 2.5 mm, 3 mm, 3.5 mm, etc.

[0048] It is understandable that, in some embodiments, a sealing gasket may be further provided on a surface of the flange plate 22 facing the housing 10 .

[0049] Exemplarily, sealing gaskets may be provided between the first surface and the outer surface of the housing 10 , between the first connecting surface and the second connecting surface, and between the second surface and the mounting platform 11 , so as to improve the sealing effect and further improve the waterproof performance.

[0050] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the air conditioner outdoor unit 100 also includes: a fireproof sheet metal 30, which is arranged on a side surface of the main plate 21 facing the outer shell 10, and a limiting portion 211 is arranged on the main plate 21, and the limiting portion 211 is used to limit the fireproof sheet metal 30.

[0051] Specifically, the limit portion 211 is arranged on the main body plate 21 and is located at some of the main body plate 21 facing the accommodating space, and the fireproof sheet metal 30 is arranged on the main body plate 21 and is suitable for separating the handle 20 from the outer shell 10, so as to achieve a fireproof effect through the setting of the fireproof sheet metal 30, block the fire transmission path between the inside of the accommodating space and the handle 20, ensure that the internal fire will not ignite the handle 20, and the external fire will not ignite the internal components of the accommodating space through the handle 20, so as to improve the fireproof performance, and the limit portion can limit the fireproof sheet metal 30, avoid the fireproof sheet metal 30 from moving, and improve the fixing stability of the fireproof sheet metal 30, so that the protection effect of the fireproof sheet metal 30 is better and the protection is more reliable.

[0052] like Figure 4 and Figure 5 As shown, further, the main body plate 21 also has a connecting hole 212, the fastener passes through the connecting hole 212 and is connected to the housing 10, the connecting hole 212 is formed in the limiting portion 211, and the height H of the limiting portion 211 is greater than 4 mm (see Figure 7 ).

[0053] Specifically, the limiting portion 211 is formed on the main body plate 21 , and a connecting hole 212 is opened on the main body plate 21 . The connecting hole 212 passes through the limiting portion 211 , and the height H of the limiting portion 211 is greater than 4 mm, such as 4.5 mm, 5 mm, 6 mm, etc.

[0054] In this way, after the head of the fastener constructed as a metal part passes through the connecting hole 212, the gap between the head of the fastener and the inner side surface of the main body plate 21 is not less than 4 mm. The fireproof sheet metal 30 is a metal part and is limited by the limiting part 211, so that the distance between the fireproof sheet metal 30 and the head of the fastener can be not less than 4 mm, so that the creepage distance between the fastener and the fireproof sheet metal 30 is greater than 4 mm, which meets the safety requirements and improves the safety and reliability of the air-conditioning outdoor unit 100.

[0055] like Figure 6 and Figure 7 As shown, the limiting portion 211 includes a boss 2111 and a limiting flange 2112 formed at one end of the boss 2111 away from the main plate 21, and a limiting groove 2113 for limiting the fireproof sheet metal 30 is defined between the limiting flange 2112, the side surface of the boss 2111 and the inner side surface of the main plate 21.

[0056] Specifically, the cross-section of the boss 2111 is in the shape of an oblong, and an oblong hole (i.e., a mounting hole) is provided on it to facilitate the insertion of fasteners. The boss 2111 can be constructed to extend vertically or obliquely relative to the inner surface of the main body plate 21. A limiting flange 2112 is provided on the free end of the boss 2111, and at least a portion of the limiting flange 2112 protrudes from the outer surface of the boss 2111, so as to define a limiting groove 2113 through the limiting flange 2112, the boss 2111 and the surface of the main body plate 21.

[0057] Therefore, the fireproof sheet metal 30 is limited by the limiting groove 2113 to improve the limiting effect of the fireproof sheet metal 30.

[0058] Furthermore, the width W2 of the limiting groove 2113 is 1.5 mm to 2.5 mm.

[0059] Exemplarily, the width of the limit groove 2113 is 1.5 mm, 2 mm or 2.5 mm, etc. This makes the width of the limit groove 2113 more reasonable, avoids the limit groove 2113 being too wide, resulting in the inability to effectively limit the fireproof sheet metal 30, and also avoids the limit groove 2113 being too small, resulting in the difficulty of assembling the fireproof sheet metal 30 into the limit groove 2113, thereby improving the assembly convenience.

[0060] It should be pointed out that an arc-shaped flange can be provided on the peripheral edge of the fireproof sheet metal 30. The arc-shaped flange is elastic and can be elastically pushed into the limiting groove 2113, which can further improve the fixing stability and reliability of the fireproof sheet metal 30 and prevent the fireproof sheet metal 30 from moving.
