[0028] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0029] The following is for reference. Figures 1-10 Description of an outdoor unit 100 of an air conditioner according to an embodiment of the present utility model.

[0030] Combination Figures 1-10 As shown, the outdoor unit 100 of the air conditioner according to this utility model can mainly include: a casing 10, a compressor 20, an outdoor heat exchanger 30, and an outdoor fan 40.

[0031] The casing 10 has an air inlet 50 on its circumferential sidewalls and an air outlet 60 on its top. This increases the air intake area, ensuring sufficient outside air is drawn into the outdoor unit 100. After heat transfer occurs between the cold air entering the outdoor unit 100 and the hot air inside, the cold air warms up and becomes hot air. Hot air, being less dense, naturally rises. The air outlet 60 at the top follows this natural upward flow, reducing wind resistance and making the exhaust from the outdoor unit 100 smoother and more efficient, thus reducing fan energy consumption and noise. Furthermore, at the same airflow rate, a larger air intake area results in a lower air intake speed, further reducing wind resistance and noise.

[0032] Furthermore, the compressor 20 is housed inside the casing 10. The casing 10 not only provides physical protection and safety for the compressor 20, but also helps to reduce the noise generated by the compressor 20. It also creates a heat dissipation environment for the compressor 20, facilitating heat dissipation.

[0033] Furthermore, the outdoor heat exchanger 30 is housed within the casing 10 and connected to the compressor 20. Specifically, after the compressor 20 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas, the outdoor heat exchanger 30 is connected to the compressor 20. This not only creates a refrigerant passage between the outdoor heat exchanger 30 and the compressor 20, ensuring the normal flow of refrigerant between them, but also allows the outdoor heat exchanger 30 to dissipate heat and cool the high-temperature, high-pressure gas output by the compressor 20.

[0034] Moreover, the outdoor heat exchanger 30 is installed inside the casing 10. The casing 10 can not only provide physical protection and safety for the outdoor heat exchanger 30, but also facilitate the formation of air ducts, optimize the airflow path, and improve the heat exchange effect of the outdoor heat exchanger 30.

[0035] Furthermore, the outdoor fan 40 is used to introduce airflow from outside the casing 10 into the casing 10 through the air inlet 50, and after heat exchange by the outdoor heat exchanger 30, it is output to the outside through the air outlet 60. Specifically, the outdoor heat exchanger 30 needs to exchange heat efficiently with the outdoor air. Natural airflow alone cannot meet the heat exchange requirements of the outdoor heat exchanger 30. By setting the outdoor fan 40, a stable and reliable airflow path can be formed, which drives the outside air into the interior of the outdoor unit 100 of the air conditioner, thereby enabling the refrigerant in the outdoor heat exchanger 30 to exchange heat with the outdoor air. In this way, the outdoor fan 40 can not only guide the airflow direction, but also increase the airflow speed, thereby improving the heat exchange efficiency of the outdoor heat exchanger 30.

[0036] Furthermore, the housing 10 includes: a main housing and a front cover 102.

[0037] The front side of the main casing is at least partially open, which facilitates the installation and disassembly of the internal components of the outdoor unit 100 of the air conditioner, and facilitates the inspection and maintenance of the internal components of the outdoor unit 100 of the air conditioner.

[0038] Furthermore, the front cover 102 is located at the open portion on the front side of the main housing. This allows the front cover 102 to close the open portion of the main housing, creating a relatively enclosed environment for the outdoor unit 100. This not only facilitates the formation of the internal air duct within the outdoor unit 100 but also prevents external objects from entering the outdoor unit 100 through the open portion on the front side of the main housing. It also isolates the internal components of the outdoor unit 100, preventing users or maintenance personnel from accidentally touching them. The main housing can abut against the front cover 102 and is securely connected via screws and threaded holes.

[0039] Furthermore, an inspection port 103 is provided on the front cover 102. In this way, when the outdoor unit 100 of the air conditioner malfunctions or requires regular maintenance, maintenance personnel can inspect, repair or replace parts inside the outdoor unit 100 through the inspection port 103 without having to remove the entire front cover 102, which facilitates the inspection and maintenance of the internal components of the outdoor unit 100.

[0040] Furthermore, the housing 10 also includes: a maintenance panel 104, and the front cover 102 has a maintenance port 103. The maintenance panel 104 is detachably installed in the maintenance port 103. When the maintenance panel 104 is installed in the maintenance port 103, it can not only prevent foreign objects from entering the air conditioner outdoor unit 100 through the maintenance port 103 and prevent users from directly contacting the internal components of the air conditioner outdoor unit 100, but also maintain the aesthetics and integrity of the air conditioner outdoor unit 100 and avoid exposing the pipes or equipment inside the air conditioner outdoor unit 100.

[0041] When the outdoor unit 100 of the air conditioner malfunctions or requires regular maintenance, the maintenance personnel can remove the inspection panel 104 and then inspect, repair or replace parts inside the outdoor unit 100 through the inspection port 103. This makes it convenient for the maintenance personnel to inspect and maintain the internal components of the outdoor unit 100.

[0042] Furthermore, the front cover 102 is provided with a first positioning part on the upper side of the access port 103, and the access panel 104 is provided with a second positioning part on the upper side. One of the first positioning part and the second positioning part is a first positioning protrusion 1051, and the other is a first positioning hole 1061. The first positioning protrusion 1051 and the first positioning hole 1061 are positioned and engaged.

[0043] Specifically, the structure and size of the first positioning protrusion 1051 and the first positioning hole 1061 correspond. During the assembly process, the first positioning protrusion 1051 and the first positioning hole 1061 are aligned, and then the first positioning protrusion 1051 is inserted into the first positioning hole 1061 so that the first positioning protrusion 1051 and the first positioning hole 1061 are positioned and engaged.

[0044] Thus, through the positioning engagement of the first positioning protrusion 1051 and the first positioning hole 1061, the installation of the inspection panel 104 can be made simpler and more direct, and the installation position of the inspection panel 104 on the front cover 102 can be determined more quickly. This not only ensures the accuracy of the installation position of the inspection panel 104 and improves the assembly precision between the inspection panel 104 and the front cover 102, but also simplifies the alignment and assembly process of the inspection panel 104 relative to the front cover 102, improving the assembly efficiency of the inspection panel 104. Furthermore, it can restrict the movement of the inspection panel 104 in the front-back and left-right directions, improving the installation stability of the inspection panel 104.

[0045] In addition, the structure of positioning and engaging the first positioning protrusion 1051 with the first positioning hole 1061 eliminates the need for fasteners, which can help reduce the number of parts in the outdoor unit 100 of the air conditioner and lower the production cost of the outdoor unit 100 of the air conditioner.

[0046] Therefore, by providing a first positioning part on the upper side of the front cover 102 corresponding to the inspection port 103, and providing a second positioning part on the upper side of the inspection panel 104, and by providing a first positioning protrusion 1051 and a first positioning hole 1061 for one of the first positioning part and the other for the second positioning part, the positioning protrusion 1051 and the first positioning hole 1061 are positioned and engaged, which not only ensures the accuracy of the installation position of the inspection panel 104 and improves the assembly accuracy between the inspection panel 104 and the front cover 102, but also simplifies the alignment process and assembly process of the inspection panel 104 relative to the front cover 102, thereby improving the assembly efficiency of the inspection panel 104.

[0047] In some embodiments of this utility model, the first positioning protrusion 1051 can be a positioning pin to further improve the installation stability of the inspection panel 104.

[0048] In some embodiments of this utility model, the housing 10 also includes a mesh cover, which has a filtering function. The mesh cover filters the air flowing through the air inlet 50, thereby improving the cleanliness of the air flowing through the air inlet 50, and thus improving the cleanliness of the internal environment of the outdoor unit air conditioner and extending the service life of the outdoor unit 100.

[0049] It should be noted that the installation of the mesh cover involves pressing its circumferential edge onto the surrounding structure, such as the chassis 108, top cover, front cover 102, and connecting plates on the main housing. Any suitable structure will suffice, as this facilitates cleaning of the mesh cover. In some specific embodiments of this invention, the mesh cover can be pressed and connected to the front cover 102 in the circumferential direction.

[0050] In some embodiments of this utility model, the outdoor fan 40 is provided with a top cover on its upper side, and the top cover is provided with multiple air outlet slots. The top cover is connected to both the outdoor heat exchanger 30 and the main housing.

[0051] In this way, the top cover can not only guide the direction of the airflow from the air outlet 60, so that the airflow is concentrated and discharged along the preset air duct, and prevent the airflow from the air outlet 60 from spreading, thus preventing the generation of eddies and turbulence inside the outdoor unit 100 of the air conditioner, but also prevent foreign objects from being sucked into the interior of the outdoor unit 100 of the air conditioner through the air outlet 60, which could cause problems such as damage to the impeller of the outdoor fan 40, motor jamming, or blockage of the outdoor heat exchanger 30. At the same time, it can also prevent users or maintenance personnel from accidentally coming into contact with the high-speed rotating impeller, thereby improving the safety of the outdoor unit 100 of the air conditioner.

[0052] Combination Figure 2 , Figure 3 and Figure 6 As shown, the first positioning part is a first positioning protrusion 1051, and a positioning plate 105 is provided on the front cover 102. The first positioning protrusion 1051 is located on the side of the positioning plate 105 facing the inspection panel 104. The second positioning part is a first positioning hole 1061, and a positioning piece 106 is provided on the inspection panel 104. The first positioning hole 1061 is located in the positioning piece 106, and the positioning piece 106 and the positioning plate 105 are in contact.

[0053] Specifically, the positioning plate 105 extends in the front-to-back direction, and the first positioning protrusion 1051 extends in the vertical direction and is disposed on the lower side of the positioning plate 105. The first positioning protrusion 1051 is connected and fixed to the positioning plate 105. The positioning plate 105 also extends to a certain size in the left-to-right direction to ensure that the first positioning protrusion 1051 has sufficient setting area and to improve the stability of the structure of the first positioning protrusion 1051.

[0054] Furthermore, the inspection panel 104 extends mainly in the left-right and up-down directions, and a positioning piece 106 extending in the front-back direction is provided. The positioning piece 106 also extends to a certain size in the left-right direction, which not only ensures that the first positioning hole 1061 has sufficient setting area, but also improves the stability and reliability of the first positioning hole 1061.

[0055] Furthermore, the first positioning part is a first positioning protrusion 1051, which is disposed on the side of the positioning plate 105 facing the inspection panel 104. The second positioning part is a first positioning hole 1061, which is disposed on the positioning piece 106. The positioning piece 106 and the positioning plate 105 are in contact. The first positioning protrusion 1051 and the first positioning hole 1061 are positioned and engaged. This not only reduces the processing difficulty of the positioning protrusion and the positioning hole and simplifies the alignment process of the positioning protrusion and the positioning hole, but also optimizes the stress on the first positioning protrusion 1051 and the first positioning hole 1061, improves the structural strength of the first positioning protrusion 1051 and the first positioning hole 1061, and prevents the first positioning protrusion 1051 and the first positioning hole 1061 from breaking or deforming due to stress.

[0056] In some embodiments of this utility model, auxiliary plates extending in the vertical direction can be provided around the bottom of the positioning plate 105. A fixing plate is provided between each auxiliary plate and the first positioning protrusion 1051. The fixing plate abuts against the first positioning protrusion 1051, and the extension line of the fixing plate passes through the center of the first positioning protrusion 1051. The fixing plate is perpendicular to the auxiliary plate. This can optimize the stress on the first positioning protrusion 1051, improve the structural strength and structural stability of the first positioning protrusion 1051, and reduce the risk of the first positioning protrusion 1051 breaking or tilting.

[0057] In some embodiments of this utility model, the first positioning protrusion 1051 is welded to the positioning plate 105, which makes the connection between the first positioning protrusion 1051 and the positioning plate 105 simple, direct, stable and reliable, and can reduce the risk of connection failure between the first positioning protrusion 1051 and the positioning plate 105.

[0058] In some embodiments of this utility model, the positioning plate 105 can also be welded onto the front cover 102, and the positioning piece 106 can also be welded onto the inspection panel 104.

[0059] Combination Figures 4-8 As shown, there are two first positioning protrusions 1051, which are spaced apart in the left and right direction. There are also two first positioning holes 1061, with each of the two first positioning protrusions 1051 and the two first positioning holes 1061 corresponding to one another.

[0060] Specifically, when the main body of the first positioning protrusion 1051 is cylindrical, if only one first positioning protrusion 1051 is provided, the inspection panel 104 can rotate around the first positioning protrusion 1051. Therefore, providing two first positioning protrusions 1051 at intervals in the left and right directions can effectively limit the rotation or offset of the inspection panel 104 relative to the front cover 102, prevent the installation position of the inspection panel 104 from being skewed, and further improve the accuracy of the installation position of the inspection panel 104, thereby improving the installation precision and efficiency of the inspection panel 104.

[0061] Furthermore, each first positioning protrusion 1051 needs to be provided with a corresponding first positioning hole 1061. Therefore, the number of first positioning holes 1061 is the same as the number of first positioning protrusions 1051.

[0062] Combination Figures 4-8 and Figure 10As shown, a connecting piece 107 is provided on the upper side of the inspection panel 104. The connecting piece 107 corresponds to and is connected to the upper side of the inspection port 103 of the front cover 102. This allows the upper side of the inspection panel 104 to fit more tightly with the position of the inspection port 103 of the front cover 102, which can further improve the stability and reliability of the structure of the inspection panel 104 and further prevent the inspection panel 104 from becoming loose or shifting.

[0063] Combination Figures 4-8 and Figure 10 As shown, the connecting piece 107 is provided with a first through hole 1071, and the front cover 102 is provided with a second through hole 1021. The first through hole 1071 and the second through hole 1021 correspond to each other and are connected by a first fastener 701.

[0064] Specifically, a first through hole 1071 is provided on the connecting piece 107, and a second through hole 1021 is provided on the front cover 102. The first through hole 1071 and the second through hole 1021 correspond in structure and position. The first fastener 701 is sequentially passed through the first through hole 1071 and the second through hole 1021, thereby connecting and fixing the connecting piece 107 and the front cover 102. This not only makes the connection between the connecting piece 107 and the front cover 102 simple, direct, stable and reliable, but also facilitates the installation and disassembly of the connecting piece 107 and the front cover 102, and facilitates the inspection and maintenance of the internal components of the indoor unit of the air conditioner. Moreover, it can effectively prevent the inspection panel 104 from loosening or shifting, further improving the stability and reliability of the structure of the inspection panel 104.

[0065] In some embodiments of this utility model, the first through hole 1071 and the second through hole 1021 can be threaded holes, and the first fastener 701 can be a screw.

[0066] Combination Figures 4-8 As shown, the connecting piece 107 is spaced between the two first positioning protrusions 1051.

[0067] Specifically, the first positioning hole 1061 is positioned relatively close to the left and right edges of the inspection panel 104, and a connecting piece 107 is positioned in the middle of the upper side of the inspection panel 104. The connecting piece 107 is positioned relatively spaced between the two first positioning protrusions 1051. This not only prevents structural interference between the connecting piece 107 and the first positioning protrusions 1051 and ensures the rationality of the structure of the inspection panel 104, but also effectively controls the production cost of the inspection panel 104 and prevents necessary material waste caused by the setting of the connecting piece 107 and the positioning piece 106.

[0068] Furthermore, the connecting piece 107 is connected to the upper side of the front cover 102 corresponding to the inspection port 103. This not only further improves the stability and reliability of the structure of the inspection panel 104 and further prevents the inspection panel 104 from becoming loose or shifting, but also prevents the middle part of the inspection panel 104 from being dented or deformed due to force, thereby improving the rigidity and bending resistance of the inspection panel 104 after assembly.

[0069] Combination Figure 5 and Figure 9 As shown, the housing 10 also includes a chassis 108. The bottom of the front cover 102 is provided with a third positioning part 1022, and the chassis 108 is provided with a fourth positioning part 1081. One of the third positioning part 1022 and the fourth positioning part 1081 is a second positioning protrusion, and the other is a second positioning hole. The second positioning protrusion and the second positioning hole are positioned and engaged.

[0070] Specifically, the structure and size of the second positioning protrusion and the second positioning hole correspond. During the assembly process, the second positioning protrusion and the second positioning hole are aligned, and the second positioning protrusion is inserted into the second positioning hole so that the second positioning protrusion and the second positioning hole are positioned and engaged.

[0071] Thus, through the positioning and engagement of the second positioning protrusion and the second positioning hole, the assembly between the chassis 108 and the front cover 102 can be made simpler and more direct, and the installation position of the front cover 102 relative to the chassis 108 can be determined more quickly. This not only ensures the accuracy of the installation position of the front cover 102 relative to the chassis 108 and improves the assembly precision between the chassis 108 and the front cover 102, but also simplifies the alignment and assembly process between the chassis 108 and the front cover 102, improving the assembly efficiency between the chassis 108 and the front cover 102. Furthermore, it can restrict the relative movement between the chassis 108 and the front cover 102 in the front-rear and left-right directions, improving the assembly stability between the chassis 108 and the front cover 102.

[0072] It should be noted that after assembly, the inspection panel 104 abuts against the front cover 102 on the upper side and the left and right sides, and against the chassis 108 on the lower side.

[0073] In addition, the structure of positioning with the second positioning protrusion and the second positioning hole eliminates the need for fasteners, which can help reduce the number of parts in the outdoor unit 100 of the air conditioner and lower the production cost of the outdoor unit 100 of the air conditioner.

[0074] In some embodiments of this utility model, the third positioning part 1022 is a second positioning protrusion, and the fourth positioning part 1081 is a second positioning hole. The second positioning protrusion can be a positioning pin.

[0075] Combination Figure 5 and Figure 9As shown, there are two second positioning protrusions, spaced apart in the left and right direction, and two second positioning holes, with each second positioning hole corresponding to one of the two second positioning protrusions.

[0076] Specifically, when the main body of the second positioning protrusion is cylindrical, if there is only one second positioning protrusion, the front cover 102 can rotate relative to the chassis 108 around the second positioning protrusion. Therefore, setting two second positioning protrusions at intervals in the left and right directions can effectively limit the rotation or offset of the front cover 102 relative to the chassis 108, prevent the assembly position of the front cover 102 relative to the chassis 108 from being skewed, and further improve the assembly accuracy and assembly stability between the chassis 108 and the front cover 102.

[0077] Furthermore, each second positioning protrusion needs to be provided with a corresponding second positioning hole. Therefore, the number of second positioning holes is the same as the number of second positioning protrusions.

[0078] Combination Figure 5 , Figure 9 and Figure 10 As shown, a mounting base 1082 is provided on the chassis 108, and the mounting base 1082 is connected and fixed to the access panel 104. Specifically, this allows the lower side of the access panel 104 to fit more tightly with the chassis 108, which can further improve the stability and reliability of the access panel 104 structure and further prevent the access panel 104 from loosening or shifting.

[0079] In some embodiments of this utility model, two mounting bases 1082 are provided, and the two mounting bases 1082 are spaced apart in the left and right directions. This can prevent local stress concentration on the lower side of the inspection panel 104 and reduce the risk of deformation of the inspection panel 104.

[0080] Combination Figure 5 , Figure 9 and Figure 10 As shown, the mounting base 1082 is provided with a third through hole 1083, and the inspection panel 104 is provided with a fourth through hole 1041. The third through hole 1083 and the fourth through hole 1041 correspond to each other and are connected by a second fastener 702.

[0081] Specifically, a third through hole 1083 is provided on the mounting base 1082, and a fourth through hole 1041 is provided on the inspection panel 104. The third through hole 1083 and the fourth through hole 1041 correspond in structure and position. The second fastener 702 is sequentially passed through the third through hole 1083 and the fourth through hole 1041, thereby connecting and fixing the mounting base 1082 and the inspection panel 104. This not only makes the connection between the mounting base 1082 and the inspection panel 104 simple, direct, stable and reliable, but also facilitates the installation and disassembly between the chassis 108 and the inspection panel 104. In addition, it can further prevent the inspection panel 104 from loosening or shifting, and further improve the stability and reliability of the structure of the inspection panel 104.

[0082] In some embodiments of this utility model, the third through hole 1083 and the fourth through hole 1041 can be threaded holes, and the second fastener 702 can be a screw.

[0083] In some embodiments of this utility model, the inspection panel 104 is provided with a pipe groove and a mounting part, wherein the mounting part is protruding forward, and the condenser pipe inside the outdoor unit 100 of the air conditioner can extend from the inside of the outdoor unit 100 of the air conditioner through the pipe groove. The pipe groove extends from the center position of the front side of the mounting part to the upper edge of the inspection panel 104, and the upper side of the inspection panel 104 is open at the position corresponding to the pipe groove.

[0084] Thus, when the condenser pipe extends through the access panel 104 to the outside of the outdoor unit 100 of the air conditioner, the condenser pipe can be moved vertically to the center of the mounting section from the open area corresponding to the pipe groove on the upper side of the access panel 104, instead of moving the condenser pipe directly through the center of the mounting section by horizontal movement. This reduces the assembly process between the condenser pipe and the access panel 104 and lowers the installation difficulty of the access panel 104.

[0085] Furthermore, the mounting section is provided with mounting holes, which are used to install and fix the valve body. The valve body is used to connect to the condenser pipe so as to control the flow and cut-off of refrigerant in the condenser pipe. That is to say, when the valve of the valve body is open, the refrigerant circulates normally, and when the valve of the valve body is closed, the flow of refrigerant will be cut off.

[0086] Furthermore, the front cover 102 is provided with a downwardly extending groove cover plate at the position corresponding to the inspection port 103. The shape and position of the groove cover plate correspond to the through-pipe groove. The size of the groove cover plate is slightly larger than the size of the through-pipe groove. The groove cover plate is used to cover the through-pipe groove. However, the groove cover plate does not cover the through-pipe groove portion corresponding to the front side of the mounting part to prevent structural interference between the groove cover plate and the condenser pipe.

[0087] Furthermore, the groove cover plate abuts against the side of the mounting part, which helps to improve the stability of the condenser tube and prevent the condenser tube from shifting or shaking in the tube groove.
