DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides an air-conditioning outdoor unit 1, which is connected to an air-conditioning indoor unit. The air-conditioning outdoor unit 1 includes a fan (not shown in the figure), a compressor (not shown in the figure), a heat exchanger (not shown in the figure), a pipe (not shown in the figure) and an air-conditioning casing 12. The fan, the compressor and the heat exchanger are all arranged in the air-conditioning casing 12. The pipe connects the compressor and the heat exchanger, and is connected to the air-conditioning indoor unit via the air-conditioning casing 12.

[0025] The pipeline is connected to the compressor and the heat exchanger, and passes through the air conditioner housing 12 to communicate with the air conditioner indoor unit to form a refrigerant flow path. Exemplarily, the pipeline generally includes a high-pressure pipe and a low-pressure pipe, and the high-pressure pipe and the low-pressure pipe both pass through the air conditioner housing 12 to communicate with the air conditioner indoor unit.

[0026] The fan is used to drive the air flow in the air-conditioning housing 12 to facilitate heat exchange between the air and the heat exchanger.

[0027] The compressor is used to drive the refrigerant to circulate in the pipeline so that the air conditioner indoor unit connected to the pipeline can achieve the effect of cooling or heating.

[0028] Please refer to Figure 2 and Figure 3 In a specific embodiment, the air conditioner casing 12 includes a shell 121 and an insect-proof plate 122 .

[0029] The housing 121 is used to install the fan, the compressor and the heat exchanger, so as to protect the fan, the compressor and the heat exchanger, reduce the probability of damage to the fan, the compressor and the heat exchanger, and thus extend the service life of the air conditioner outdoor unit 1. In a specific embodiment, the housing 121 can be made of metal to ensure that the housing 121 has a high structural strength, so as to better protect the internal components. The housing 121 has a pipe hole 121A, and the pipeline can pass through the housing 121 through the pipe hole 121A.

[0030] The insect-proof plate 122 is arranged at the pipe hole 121A, and the insect-proof plate 122 includes a pipe passing portion 1221 and a mounting portion 1222. The mounting portion 1222 is connected to the pipe passing portion 1221 and is arranged around the circumference of the pipe passing portion 1221. The mounting portion 1222 is connected to the shell 121. The pipe can pass through the pipe passing portion 1221, and the pipe passing portion 1221 maintains contact with the outer wall of the pipe to reduce the probability of insects and ants entering the shell 121 from the gap between the pipe and the insect-proof plate 122, thereby protecting the fan, compressor and heat exchanger in the shell 121, reducing the probability of damage to the fan, compressor and heat exchanger, and thus allowing the air-conditioning outdoor unit 1 to have a longer service life.

[0031] Please refer to Figure 2 and Figure 3Specifically, the tube-passing portion 1221 includes a main body 1221-1 and a connecting structure 1221-2. The main body 1221-1 has a tube-passing hole 1221-1A and a plurality of slits 1221-1B connected to the tube-passing hole 1221-1A. The plurality of slits 1221-1B are arranged at intervals along the circumference of the tube-passing hole 1221-1A. The portion of the main body 1221-1 located between two adjacent slits 1221-1B is formed as a petal body 1221-11; each slit 1221-1B is correspondingly provided with a plurality of connecting structures 1221-2. The plurality of connecting structures 1221-2 are arranged at intervals along the length direction of the slit 1221-1B. The connecting structure 1221-2 connects the petals 1221-11 on both sides of the slit 1221-1B.

[0032] When inserting the pipe, the pipe overlaps with part of the connecting structure 1221-2, so that the connecting structure 1221-2 in the overlapping area is broken or the connecting structure 1221-2 and the flap body 1221-11 are broken, so that the flap body 1221-11 on both sides of the slit 1221-1B can be deformed, thereby increasing the aperture of the through-tube hole 1221-1A, making it easier for the pipe to pass through the through-tube hole 1221-1A; and the connecting structure 1221-2 outside the overlapping area of ​​the pipe remains connected, so that the hole wall of the through-tube hole 1221-1A with the increased aperture fits tightly with the outer peripheral side of the pipe, further reducing the gap between the through-tube part 1221 and the pipe, so as to reduce the probability of insects and ants entering the shell 121 through the gap, thereby allowing the air-conditioning outdoor unit 1 to have a longer service life.

[0033] Please refer to Figure 2 and Figure 3 In a specific embodiment, the material of the tube portion 1221 and the mounting portion 1222 includes at least one of silicone rubber and EPDM (Ethylene Propylene Diene Monomer), so as to facilitate the breaking of the connecting structure 1221-2 and the deformation of the petal body 1221-11, so that the tube hole 1221-1A can fully fit the outer peripheral side of the pipeline to prevent insects and ants from entering the housing 121 through the gap. In other embodiments, the tube portion 1221 and the mounting portion 1222 can also be other flexible materials that can undergo elastic deformation.

[0034] Furthermore, the material of the tube portion 1221 and the mounting portion 1222 can both be silicone rubber, and the tube portion 1221 and the mounting portion 1222 are integrally formed to ensure a stable connection between the tube portion 1221 and the mounting portion 1222. In addition, the tube portion 1221 and the mounting portion 1222 are integrally formed to improve the production efficiency of the insect-proof plate 122, thereby improving the production efficiency of the air conditioner housing 12.

[0035] It can be understood that different thicknesses of the pipe portion 1221 will result in different deformations of the petal body 1221-11. During use, the pipe portion 1221 with different thicknesses can be selected according to the type of pipe, so that the deformation of the petal body 1221-11 meets the requirement of filling the gap between the pipe and the pipe hole 1221-1A, thereby reducing the probability of insects and ants entering the shell 121 through the gap, thereby allowing the air-conditioning outdoor unit 1 to have a longer service life.

[0036] Please refer to Figure 2-5 In a specific embodiment, the mounting portion 1222 includes a mounting sub-portion 1222-1, a first extension sub-portion 1222-2, and a second extension sub-portion 1222-3. The mounting sub-portion 1222-1 is connected to the tube portion 1221 and is arranged around the tube portion 1221; the first extension sub-portion 1222-2 is connected to one side of the mounting sub-portion 1222-1 and extends in a direction away from the mounting sub-portion 1222-1; the second extension sub-portion 1222-3 is connected to the other side of the mounting sub-portion 1222-1 and extends in a direction away from the mounting sub-portion 1222-1. wherein, the first extension sub-portion 1222-2 and the second extension sub-portion 1222-3 are spaced apart from each other, and the mounting sub-portion 1222-1, the first extension sub-portion 1222-2 and the second extension sub-portion 1222-3 are arranged to surround a mounting groove 1222A, and the hole wall of the through-tube hole 121A is located in the mounting groove 1222A, so that the insect-proof plate 122 is connected to the shell 121, and the probability of the insect-proof plate 122 being separated from the shell 121 can be reduced, so as to reduce the probability of insects and ants entering the shell 121 through the through-tube hole 121A, thereby extending the service life of the air-conditioning outdoor unit 1.

[0037] Please refer to Figure 2-5 In a specific embodiment, the shell 121 includes a shell body 1211 and a convex portion 1212 protruding from the shell body 1211, the convex portion 1212 is arranged around the tube hole 121A, the convex portion 1212 abuts against the groove wall of the mounting groove 1222A, and the groove wall of the mounting groove 1222A can be deformed, so that the convex portion 1212 is embedded in the groove wall of the mounting groove 1222A, so as to increase the contact area between the shell 121 and the mounting portion 1222, so as to improve the connection stability between the shell 121 and the mounting portion 1222.

[0038] It is understandable that a groove may be provided at the corresponding position between the groove wall of the installation groove 1222A and the protrusion 1212 , and the protrusion 1212 is embedded in the groove, which can also increase the connection stability between the shell 121 and the installation portion 1222 .

[0039] Please refer to Figure 2-5In a specific embodiment, the convex portion 1212 includes a first convex portion 1212-1 and a plurality of second convex portions 1212-2, the first convex portion 1212-1 is arranged around the circumference of the through-tube hole 121A; the plurality of second convex portions 1212-2 are convexly arranged on the side of the first convex portion 1212-1 away from the shell body 1211, and the two adjacent second convex portions 1212-2 are arranged at intervals, so that when the convex portion 1212 abuts against the groove wall of the mounting groove 1222A, the groove wall of the mounting groove 1222A is partially recessed to accommodate the second convex portions 1212-2, thereby further increasing the contact area between the shell 121 and the mounting portion 1222, thereby increasing the connection stability between the shell 121 and the mounting portion 1222, and thereby reducing the probability of the insect-proof plate 122 detaching from the air-conditioning shell 12.

[0040] It can be understood that a stepped groove corresponding to the first protrusion portion 1212-1 and the second protrusion portion 1212-2 can be set on the groove wall of the installation groove 1222A to accommodate the first protrusion portion 1212-1 and the second protrusion portion 1212-2, which can also increase the contact area between the shell 121 and the installation portion 1222 to reduce the probability of the insect-proof plate 122 detaching from the air-conditioning casing 12.

[0041] It can be understood that the sum of the widths of the first protrusion portion 1212-1 and the second protrusion portion 1212-2 can be equal to the width of the bottom of the mounting groove 1222A, so that the mounting portion 1222 can be exactly engaged with the shell 121. Similarly, the contact area between the mounting portion 1222 and the shell 121 can be increased to improve the connection stability between the insect protection plate 122 and the air-conditioning casing 12.

[0042] Please refer to Figure 3 In a specific embodiment, the shell 121 also includes a plurality of snap-fitting portions 1213, which are protruding from the second convex portion 1212-2 away from the shell body 1211; the first extension portion 1222-2 has a plurality of slots 1222-2A, each of which passes through the first extension portion 1222-2 and is connected to the mounting slot 1222A. Two adjacent slots 1222-2A are arranged at intervals, and the snap-fitting portions 1213 are snap-fitted to the slots 1222-2A one-to-one to reduce the probability of the mounting portion 1222 detaching from the shell 121, thereby improving the connection stability between the insect-proof plate 122 and the shell 121. In the embodiment of the present application, there is no specific limitation on the number of the clamping parts 1213 and the clamping slots 1222-2A. The clamping parts 1213 and the clamping slots 1222-2A can be arranged in a one-to-one correspondence. For example, the number of the clamping parts 1213 and the clamping slots 1222-2A can be 1, 2, 3, etc.

[0043] Please refer to Figure 2 , Figure 3 and Figure 6 In a specific embodiment, the mounting portion 1222 has a broken groove 1222B, which penetrates the mounting portion 1222 and is connected to a slit 1221-1B. After the pipe is passed through the pipe hole 121A, the connecting structure 1221-2 in the corresponding slit 1221-1B can be torn through the broken groove 1222B, so that the petals 1221-11 on both sides of the corresponding slit 1221-1B are arranged at an angle, so that the opening 1221-1C is formed through the broken groove 1222B, so that the pipe can be installed in the pipe hole 1221-1A through the opening 1221-1C, and then the mounting portion 1222 is clamped with the air conditioner housing 12 to achieve the installation of the insect-proof plate 122.

[0044] Please refer to Figure 5 In a specific embodiment, the shell 121 includes a bracket 1214 and an outer box body 1215, the outer box body 1215 is covered outside the bracket 1214, the pipe hole 121A is located on the bracket 1214, the outer box body 1215 has an outer pipe hole 1215A, the outer pipe hole 1215A is arranged corresponding to the pipe hole 121A, the mounting portion 1222 is in contact with the inner wall of the outer box body 1215, and is arranged around the outer pipe hole 1215A, so that the outer pipe hole 1215A can be sealed to prevent insects and ants from entering the air-conditioning casing 12 through the gap between the bracket 1214 and the outer box body 1215.

[0045] And because the mounting portion 1222 abuts against the inner wall of the outer box body 1215, when the insect-proof plate 122 is first installed on the bracket 1214 and then the pipe is passed through, the outer box body 1215 can be used to support the mounting portion 1222 to support the insect-proof plate 122, so that when the friction between the pipe and the pipe passing portion 1221 is large, the insect-proof plate 122 can be prevented from separating from the shell 121, thereby improving the efficiency of passing through the pipe, thereby improving the assembly efficiency of the air-conditioning outdoor unit 1.

[0046] The embodiment of the present application also provides a HVAC device, including an air conditioner indoor unit and an air conditioner outdoor unit 1, wherein the air conditioner indoor unit is connected to the air conditioner outdoor unit 1 through a pipeline to form a complete refrigerant flow path.
