Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0029] The air conditioner outdoor unit provided in this application embodiment, such as Figures 1 to 7As shown, the system includes: a housing 100, which has a heat exchange chamber 110 and a mounting chamber 120 arranged sequentially along a first direction; a compressor 200 disposed in the mounting chamber 120; a return gas pipe assembly 310 and an exhaust gas pipe assembly 320 located on both sides of the compressor 200 in the first direction, the return gas pipe assembly 310 having one outlet and multiple inlets, the exhaust gas pipe assembly 320 having one inlet and multiple outlets, the outlet of the return gas pipe assembly 310 being connected to the return gas port of the compressor 200, and the inlet of the exhaust gas pipe assembly 320 being connected to the exhaust port of the compressor 200; and multiple reversing valves located above the compressor 200 and staggered in the horizontal direction, the multiple inlets of the return gas pipe assembly 310 being connected one-to-one with the multiple first interfaces of the multiple reversing valves, and the multiple outlets of the exhaust gas pipe assembly 320 being connected one-to-one with the multiple second interfaces of the multiple reversing valves, the first direction intersecting with the vertical direction.

[0030] In this outdoor unit of the air conditioner, the return pipe assembly 310 and the exhaust pipe assembly 320 are located on both sides of the compressor 200 in the first direction, and multiple reversing valves are located above the compressor 200 and are staggered in the horizontal direction. The first direction intersects with the vertical direction, which can effectively reduce the space occupied by the return pipe assembly 310, the exhaust pipe assembly 320 and the multiple reversing valves above the compressor 200 in the vertical direction, and is more conducive to the miniaturization of the outdoor unit of the air conditioner.

[0031] In some examples, such as Figures 2 to 4 As shown, the cavity wall of the mounting cavity 120 includes a detachable inspection plate (the inspection plate cover position forms an inspection port). Each reversing valve includes a valve body 460, a coil 450, and a locking member. Each valve body 460 has a mounting post 440 protruding towards the inspection plate. Multiple coils 450 are fitted onto the mounting posts 440 one by one on the side of the mounting posts 440 facing the inspection plate. Multiple locking members are screwed onto the mounting posts 440 one by one on the side of the mounting posts 440 facing the inspection plate to fix the multiple coils 450 one by one. The orthographic projections of the multiple locking members on the inspection plate are spaced apart from each other.

[0032] Multiple coils 450 are fitted one-to-one onto the mounting posts 440 on the side of the mounting posts 440 facing the inspection plate. Multiple locking parts are screwed onto the mounting posts 440 on the side of the mounting posts 440 facing the inspection plate to fix the multiple coils 450 one-to-one, so that the valve body 460 and the coils 450 are assembled together by the locking parts. Furthermore, the orthographic projections of the multiple locking parts on the inspection plate are also spaced apart from each other. In this way, when the inspection plate is removed, the multiple locking parts will not block each other when they are installed or removed at the inspection port, which facilitates the smooth operation of installing or removing multiple locking parts (such as lock nuts).

[0033] In some embodiments, such as Figures 1 to 4As shown, the inspection plate is erected along the first direction and the vertical direction. Multiple directional valves are arranged sequentially in the first direction and staggered in the second direction. The first direction, the second direction, and the vertical direction intersect each other. The horizontal direction includes both the first and second directions. Specifically, in the second direction, the directional valves farther from the inspection plate are positioned relative to the directional valves adjacent to the inspection plate: the orthographic projection of the locking element of the directional valve farther from the inspection plate onto the inspection plate is spaced apart from the orthographic projection of the valve body 460 of the directional valve adjacent to the inspection plate onto the inspection plate. This ensures that when multiple locking elements are installed or removed at the inspection port after the inspection plate is removed, the valve body 460 of the directional valve adjacent to the inspection plate will not obstruct the locking elements of the directional valves farther from the inspection plate, further guaranteeing the smooth operation of installing or removing multiple locking elements.

[0034] In some embodiments, the first direction is the left-right direction, the second direction is the front-back direction, and the inspection plate is the front side plate of the mounting cavity 120. This makes it easier for maintenance personnel to disassemble and install the inspection plate and locking parts from the front side of the air conditioner outdoor unit.

[0035] It can be that multiple directional valves include three-way valves and four-way valves; or it can be that multiple directional valves are all three-way valves (the three-way valves have a first port, a second port and a third port); or it can be that multiple directional valves are all four-way valves (the four-way valves have a first port, a second port, a third port and a fourth port), etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, so they will not be elaborated here, and all should fall within the protection scope of this application.

[0036] In one embodiment, such as Figures 1 to 6 As shown, the multiple directional control valves include a first directional control valve 410, a second directional control valve 420, and a third directional control valve 430 arranged sequentially in the first direction. In the second direction, the first directional control valve 410 and the third directional control valve 430 are located between the second directional control valve 420 and the access panel. Viewed from top to bottom, the first directional control valve 410, the second directional control valve 420, and the third directional control valve 430 are distributed according to the three vertices of a triangle. This arrangement helps to reduce the space occupied by the first directional control valve 410, the second directional control valve 420, and the third directional control valve 430 in the horizontal direction.

[0037] Alternatively, the first directional valve 410 and the third directional valve 430 may be positioned opposite each other in the first direction (not shown in this schematic diagram); or it may be as follows: Figure 3 As shown, the first reversing valve 410 and the third reversing valve 430 are offset in the second direction, etc.; all of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be repeated here, and all should fall within the protection scope of this application.

[0038] In some examples, such as Figures 2 to 6As shown, both the exhaust pipe assembly 320 and the return pipe assembly 310 include a connecting pipe and a four-way valve. One end of the connecting pipe is connected to the compressor 200, and the other end is connected to one port of the four-way valve. The outdoor unit of the air conditioner also includes an auxiliary connecting pipe 500. The other three ports of the four-way valve are connected to the first reversing valve 410, the second reversing valve 420, and the third reversing valve 430 respectively through the three auxiliary connecting pipes 500; that is: Figure 4 and Figure 5 As shown, one end of the connecting pipe 321 of the exhaust pipe assembly 320 is connected to the exhaust port of the compressor 200, and the other end is connected to one port of the four-way valve 322 of the exhaust pipe assembly 320. The other three ports of the four-way valve 322 of the exhaust pipe assembly 320 are connected to the second ports of the first reversing valve 410, the second ports of the second reversing valve 420, and the second ports of the third reversing valve 430 respectively through three auxiliary connecting pipes 500; Figure 6 As shown, one end of the connecting pipe 311 of the return gas pipe assembly 310 is connected to the return gas port of the compressor 200, and the other end is connected to one port of the four-way valve 312 of the return gas pipe assembly 310. The other three ports of the four-way valve 312 of the return gas pipe assembly 310 are connected to the first interface of the first reversing valve 410, the first interface of the second reversing valve 420, and the first interface of the third reversing valve 430 respectively through three auxiliary connecting pipes 500.

[0039] It can be, such as Figure 5 and Figure 6 As shown, the four-way connector 322 of the exhaust pipe assembly 320 is an integrally formed part (such as an integrally extruded part), while the four-way connector 312 of the return air pipe assembly 310 is a separate connecting part formed by connecting two interconnected tees. Compared with the separate connecting parts, the integrally formed part has fewer weld joints. Alternatively, both the four-way connector 322 of the exhaust pipe assembly 320 and the four-way connector 312 of the return air pipe assembly 310 can be integrally formed parts (such as integrally extruded parts); or both the four-way connector 322 of the exhaust pipe assembly 320 and the four-way connector 312 of the return air pipe assembly 310 can be separate connecting parts formed by connecting two interconnected tees; or the four-way connector 312 of the return air pipe assembly 310 can be an integrally formed part (such as an integrally extruded part), while the four-way connector 322 of the exhaust pipe assembly 320 can be a separate connecting part formed by connecting two interconnected tees, etc. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model. They will not be elaborated further here, and should all fall within the protection scope of this application.

[0040] In some examples, such as Figure 8As shown, the outdoor unit of the air conditioner also includes: an isolation component 610, which is disposed between the return air pipe assembly 310 and the side wall of the mounting cavity 120, and between the exhaust pipe assembly 320 and the side wall of the mounting cavity 120, to isolate the return air pipe assembly 310 and the side wall of the mounting cavity 120, and to prevent the exhaust pipe assembly 320 and the return air pipe assembly 310 from contacting the cavity wall of the mounting cavity 120. The isolation component 610 can be sound insulation cotton, and the minimum gap between the return air pipe assembly 310 and the side wall of the mounting cavity 120, and the minimum gap between the exhaust pipe assembly 320 and the side wall of the mounting cavity 120, are both greater than the thickness of the sound insulation cotton, such as setting the minimum gap to 15mm to 25mm.

[0041] In some examples, such as Figure 7 As shown, the outdoor unit of the air conditioner also includes: a sound insulation component 620, which is wrapped around the compressor 200 and is designed to reduce the noise transmitted to the outside during the operation of the compressor 200. The exhaust pipe assembly 320 and the return pipe assembly 310 are both located outside the sound insulation component 620. Alternatively, the sound insulation component 620 can be made of sound-absorbing cotton.

[0042] In some examples, such as Figure 6 As shown, the lower part of the return air pipe assembly 310 is provided with a first branch interface 313 (that is, the lower part of the connecting pipe 311 of the return air pipe assembly 310 is a U-shaped structure with the opening facing upwards). The outdoor unit of the air conditioner also includes a first vibration damping component 710, a first connecting pipe 720, and a first pressure switch 730. The first pressure switch 730 is located above one side of the first branch interface 313 and is connected to the first branch interface 313 through the first connecting pipe 720. The first vibration damping component 710 connects the first connecting pipe 720 and the return air pipe assembly 310, which helps to reduce the vibration generated by the first pressure switch 730. The first vibration damping component 710 can be a rubber component.

[0043] In some examples, such as Figure 4 and Figure 5 As shown, the lower part of the exhaust pipe assembly 320 is provided with a counterweight 324 and a second branch interface 323 (i.e., the lower part of the connecting pipe 321 of the exhaust pipe assembly 320 is a U-shaped structure with the opening facing upwards). The counterweight 324 can reduce the vibration generated by the U-shaped structure at the lower part of the exhaust pipe assembly 320. The air conditioner outdoor unit also includes a second vibration damper 810, a second connecting pipe 820, and a second pressure switch 830. The second pressure switch 830 is located above one side of the second branch interface 323 and is connected to the second branch interface 323 through the second connecting pipe 820. The second vibration damper 810 connects the second connecting pipe 820 and the exhaust pipe assembly 320, which helps to reduce the vibration generated by the second pressure switch 830. The second vibration damper 810 can be a rubber component.

[0044] Of course, a counterweight can also be installed at the lower U-shaped structure of the return air pipe assembly 310 to reduce vibration at the lower part of the return air pipe assembly 310 (not shown in the figure of this scheme), which can also achieve the purpose of this application. Its purpose has not deviated from the design concept of this utility model, and will not be elaborated here. It should also fall within the protection scope of this application.

[0045] The air conditioner provided in this application embodiment (not shown in the figure) includes the air conditioner outdoor unit described in any of the above embodiments.

[0046] This air conditioner possesses all the advantages of the outdoor unit provided in any of the above embodiments, which will not be repeated here.

[0047] In summary, the technical solution provided in this application embodiment has the return pipe assembly and the exhaust pipe assembly located on both sides of the compressor in the first direction, and multiple reversing valves located above the compressor and staggered in the horizontal direction. The first direction intersects with the vertical direction, which can effectively reduce the space above the compressor occupied by the return pipe assembly, the exhaust pipe assembly, and multiple reversing valves in the vertical direction, and is more conducive to the miniaturization of the air conditioner outdoor unit.
