Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an outdoor unit for an air conditioner. Background Technology

[0002] A shut-off valve is typically installed between the high-pressure and low-pressure sides of a refrigeration cycle. It controls the flow of refrigerant, for example, by being fully or partially closed to regulate the amount of refrigerant flowing through the cycle. When maintenance or repair is required, the shut-off valve can be fully closed to prevent refrigerant leakage and protect the system from excessive pressure or other abnormal conditions. Shut-off valves are usually controlled by electric actuators, such as those in the air conditioning system's control system. They can also be manually or pneumatically controlled when needed. For ease of installation and management, shut-off valves are typically installed in the outdoor unit.

[0003] After the refrigerant piping of the shut-off valve is installed, there will be a certain gap between the refrigerant piping and the surrounding housing. To accommodate two-pipe, three-pipe, and four-pipe air conditioning systems, the opening through which the refrigerant piping passes is designed to be relatively large, allowing more refrigerant piping to pass while also providing some assembly space. This allows rodents or other small animals to potentially enter the outdoor unit, posing a risk of chewing cables, damaging components, or nesting inside the housing, leading to air conditioning system malfunctions.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0054] The following is a reference to the appendix. Figures 1 to 19 The implementation method of the air conditioner outdoor unit provided in this application will be described.

[0055] The outdoor unit of an air conditioner is a component of an air conditioning system.

[0056] An air conditioning system executes a refrigeration cycle using a compressor 11, a condenser, a throttling element, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0057] Low-temperature, low-pressure refrigerant enters compressor 11, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0058] A throttling element (taking an electronic expansion valve as an example) expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant that has expanded in the electronic expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor 11. The evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioning system regulates the temperature of the indoor space.

[0059] An air conditioner outdoor unit refers to the part of the refrigeration cycle that includes the compressor 11 and the outdoor heat exchanger. An air conditioner indoor unit includes the indoor heat exchanger, and an electronic expansion valve can be provided in either the indoor or outdoor unit.

[0060] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0061] An air conditioner outdoor unit includes: an outer casing, which is roughly rectangular box-shaped. The casing is made of steel plate (such as galvanized steel plate) or other metal materials, possessing corrosion resistance, durability, and sufficient strength. The casing protects the internal components from external environmental damage (such as wind, rain, dust, etc.), prevents airborne impurities (such as leaves, etc.) from entering the interior, and maintains the long-term stable operation of the air conditioner outdoor unit.

[0062] In some embodiments of this application, the outer casing may be provided with ventilation holes, grilles, or heat sinks to ensure that the outdoor heat exchanger 10 installed therein can achieve ideal heat dissipation efficiency. The bottom of the outer casing is provided with a bracket or mounting holes for fixing the outdoor unit of the air conditioner to a wall, platform, or other bracket to ensure stable installation and the ability to withstand vibrations during operation.

[0063] An installation cavity 12 is formed inside the outer casing. Components such as the compressor 11, outdoor heat exchanger 10, outdoor fan, shut-off valve 27, and piping are all installed in the installation cavity 12.

[0064] The housing includes a base plate 14. In some embodiments of this application, the housing also includes a top plate, two side plates, a front plate, and a rear plate, these plate-like components collectively forming a mounting cavity 12 within the housing. In some embodiments of this application, the base plate 14 is a generally rectangular metal plate-like component, forming the bottom portion of the mounting cavity 12. The compressor 11 is mounted on the base plate 14. The base plate 14 provides support for the compressor 11 and also serves to protect and absorb vibrations. In the following description, unless otherwise specified, all terms are as follows: Figure 2 The front view shown is the reference point, where "up" and "down" indicate the direction in the height direction of the shell, "left" and "right" indicate the direction in the length direction of the shell, and "front" and "back" indicate the direction in the width direction of the shell.

[0065] In some embodiments of this application, the compressor 11 is installed in the central area of ​​the base plate 14, and the compressor 11 is fixedly connected to the base plate 14 to avoid vibration or displacement during operation.

[0066] In some embodiments of this application, the outdoor heat exchanger 10 is mounted on the side of the base plate 14, thereby enabling the outdoor heat exchanger 10 to exchange heat efficiently with the outside air.

[0067] The housing also includes a shut-off valve 27, which is installed between the high-pressure side and the low-pressure side of the refrigeration cycle to control the flow of refrigerant.

[0068] In some embodiments of this application, the number of shut-off valves 27 in the housing is two. The layout of the shut-off valves 27 matches a two-pipe refrigeration cycle. A two-pipe refrigeration cycle is the most common air conditioning piping configuration, where the outdoor unit and indoor unit are connected via liquid-side piping and gas-side piping. Correspondingly, the shut-off valves 27 include a liquid-side shut-off valve 27 and a gas-side shut-off valve 27, with the liquid-side shut-off valve 27 disposed on the liquid-side piping and the gas-side shut-off valve 27 disposed on the gas-side piping.

[0069] In some embodiments of this application, to increase flexibility, the outdoor unit and indoor unit of the air conditioner can be connected by three pipes. The layout of the shut-off valves 27 matches the three-pipe refrigeration cycle, with a corresponding shut-off valve 27 installed on each pipe. The three-pipe refrigeration cycle can be used in environments requiring both cooling and heating, simultaneously meeting both cooling and heating needs.

[0070] In some embodiments of this application, to cope with more complex usage environments, the outdoor unit and indoor unit of the air conditioner can be connected by four pipes. The layout of the shut-off valves 27 matches the four-pipe refrigeration cycle, with a corresponding shut-off valve 27 installed on each pipe. The four-pipe refrigeration cycle can simultaneously achieve cooling and heating, and can also ensure that the cooling and heating needs of different areas are met simultaneously.

[0071] In some embodiments of this application, the shut-off valve 27 includes a valve body, in which a generally cross-shaped flow channel is formed. A first interface 28 is formed at the lower end of the valve body for fluid connection to a refrigerant piping near the indoor unit; a second interface 29 is formed at the rear end of the valve body for fluid connection to a refrigerant piping near the outdoor unit; a maintenance end 31 is provided at the upper end of the valve body, sealed by a removable valve cover; an operating end 30 is provided at the front end of the valve body, with a removable nut that can be removed when necessary to drive the valve core. A fixing part is also provided on the valve body, constructed on flanges 32 on both sides of the valve body, extending outwards from the valve body.

[0072] like Figures 1 to 8 As shown, in some embodiments of this application, the shut-off valve 27 is mounted on the mounting assembly 13. The mounting assembly 13 is used to support and secure the shut-off valve 27, preventing it from moving or loosening during use or transportation, while also facilitating the disassembly and installation of the shut-off valve 27 by operators. The mounting assembly 13 also provides a degree of protection against damage to the shut-off valve 27 from external impacts.

[0073] In some embodiments of this application, the mounting assembly 13 includes a first mounting element 15 and a second mounting element 16 that are independently arranged with each other. The first mounting element 15 is used to support and fix at least one shut-off valve 27, and the second mounting element 16 is used to support and fix one or more shut-off valves 27. The second mounting element 16 is disposed on the base plate 14, and the first mounting element 15 and the second mounting element 16 are arranged sequentially from top to bottom along the height direction of the housing.

[0074] In some embodiments of this application, the first mounting element 15 is a generally plate-shaped component, and the second mounting element 16 is also a generally plate-shaped component; the two are used together. The first mounting element 15 and the second mounting element 16 themselves have sufficient thickness to support the weight of the shut-off valve 27 and vibrations during operation.

[0075] In some embodiments of this application, the second mounting element 16 can be used alone.

[0076] In some embodiments of this application, the first mounting element 15 may be a bracket, and the second mounting element 16 may also be a bracket; the two may be used together; or the second mounting element 16 may be used alone.

[0077] In some embodiments of this application, the first mounting element 15 and the second mounting element 16 are made of corrosion-resistant, high-strength metal materials, such as galvanized steel or stainless steel, which are sufficient to withstand pressure and temperature changes in the air conditioning system.

[0078] As shown in the figure, the first mounting element 15 and the second mounting element 16, which are in the shape of plates, will be used as examples for introduction.

[0079] The first mounting element 15 and the second mounting element 16 extend in a direction that is substantially parallel to the length direction.

[0080] In some embodiments of this application, the second mounting element 16 has a main mounting portion 17, which is located approximately at the upper edge of the second mounting element 16. The main mounting portion 17 can mount a plurality of shut-off valves 27 in a configuration arranged along the same direction (e.g., the length direction).

[0081] In some embodiments of this application, one refrigerant port of the shut-off valve 27 is located on one side of the second mounting element 16, and the other refrigerant port is located on the other side of the second mounting element 16. For example, the first port 28 of the shut-off valve 27, which connects to the refrigerant pipe near the indoor unit, is located on the front side of the second mounting element 16, and the second port 29, which connects to the refrigerant pipe near the outdoor unit, is located on the rear side of the second mounting element 16, so that the operating end 30 is located in a relatively forward position and is in a relatively extended state, which facilitates operation. That is, the shut-off valve 27 is installed on the second mounting element 16 with the operating end 30 facing forward and the second port 29, which connects to the refrigerant pipe near the outdoor unit, penetrating through it.

[0082] In some embodiments of this application, the main mounting portion 17 includes a plurality of main mounting notches 18, which are arranged along the length direction. Each main mounting notch 18 is correspondingly provided with a shut-off valve 27. The main mounting notches 18 are generally U-shaped, and the opening of the U-shaped main mounting notch 18 is formed at the upper edge of the second mounting element 16.

[0083] In some embodiments of this application, the bottom heights of the plurality of main mounting notches 18 are the same.

[0084] In some embodiments of this application, the bottom heights of the plurality of main mounting notches 18 are different.

[0085] In some embodiments of this application, the bottom curvature of the plurality of main mounting notches 18 is the same.

[0086] In some embodiments of this application, the bottom curvature of the plurality of main mounting notches 18 is different.

[0087] In some embodiments of this application, the width of the plurality of main mounting notches 18 is the same.

[0088] In some embodiments of this application, the widths of the plurality of main mounting notches 18 are different.

[0089] In some embodiments of this application, the main mounting part 17 is also provided with main fixing holes on both sides corresponding to the main mounting notch 18; the bolt passes through the fixing part and the main fixing hole on the valve body in sequence, so that the shut-off valve 27 can be fixed at a predetermined position in the main mounting notch 18.

[0090] In some embodiments of this application, the main mounting part 17 can mount three shut-off valves 27 in a configuration that is arranged along the length direction.

[0091] In some embodiments of this application, the main mounting portion 17 includes three main mounting notches 18 arranged along its length. Each main mounting notch 18 corresponds to a shut-off valve 27. The main mounting notches 18 are generally U-shaped, with the opening of the U-shaped main mounting notch 18 formed at the upper edge of the second mounting element 16.

[0092] In some embodiments of this application, two main mounting notches 18 have the same height, while another main mounting notch 18 has a different height.

[0093] When used in two-pipe or three-pipe air conditioning systems, the installation requirements of two or three shut-off valves 27 can be met by using only the second mounting element 16. Alternatively, the second mounting element 16 can be used to install some of the shut-off valves 27, while the first mounting element 15 can be used to install the other part of the shut-off valves 27, making the layout within the housing more flexible.

[0094] In some embodiments of this application, the first mounting element 15 has an auxiliary mounting portion 19, which is generally located at the upper edge of the first mounting element 15. The auxiliary mounting portion 19 can mount at least one shut-off valve 27 in a configuration arranged along the same direction, such as the length direction.

[0095] In some embodiments of this application, one refrigerant port of the shut-off valve 27 is located on one side of the first mounting element 15, and the other refrigerant port is located on the other side of the first mounting element 15; for example, the first port 28 of the shut-off valve 27 is located on the front side of the first mounting element 15, and the second port 29 is located on the rear side of the first mounting element 15, so that the operating end 30 is located in a relatively forward position and is in a relatively extended state, which facilitates operation.

[0096] In some embodiments of this application, the auxiliary mounting portion 19 includes at least one auxiliary mounting notch 20. The auxiliary mounting notch 20 is correspondingly disposed with a shut-off valve 27. The auxiliary mounting notch 20 is generally U-shaped, with the opening of the U-shaped auxiliary mounting notch 20 formed at the upper edge of the first mounting element 15.

[0097] In some embodiments of this application, the first mounting element 15 includes an auxiliary mounting notch 20. When used in a four-pipe air conditioning system, the first mounting element 15 and the second mounting element 16 are used together, with one shut-off valve 27 supported by the first mounting element 15 and the other three shut-off valves 27 supported by the second mounting element 16.

[0098] In some embodiments of this application, the first mounting element 15 and the second mounting element 16 are detachably fixedly connected.

[0099] In some embodiments of this application, the first mounting element 15 is generally trapezoidal; compared with a rectangular design, the trapezoidal first mounting element 15 can not only better disperse stress, reduce shear deformation and stress concentration, resist deformation and maintain structural stability, but also avoid pipes and other components in the mounting cavity 12 by adjusting the angle and size, thereby achieving a better layout in a limited space; it is also more suitable for mounting gap layouts with fewer gaps at the top and more gaps at the bottom.

[0100] The first mounting element 15 and the second mounting element 16 are detachably and fixedly connected by one or more sets of snap-fit ​​assemblies 21. The snap-fit ​​assembly 21 includes a matching snap-fit ​​element and a snap-fit ​​opening. One of the snap-fit ​​element and the snap-fit ​​opening is provided on the first mounting element 15, and the other is provided on the second mounting element 16; the two cooperate to fix each other.

[0101] In some embodiments of this application, the first mounting element 15 and the second mounting element 16 are connected by a first snap-fit ​​assembly and a second snap-fit ​​assembly. The first snap-fit ​​assembly includes a matching first snap-fit ​​element and a first snap-fit ​​opening. The first snap-fit ​​element is disposed on the main mounting portion 17 of the second mounting element 16, extending from rear to front in a protruding form. The first snap-fit ​​interface is disposed on one side of the first mounting element 15, and the first snap-fit ​​interface is a through hole extending in the vertical direction. The first snap-fit ​​element can slide up and down in the first snap-fit ​​interface until it abuts against the lower edge of the first snap-fit ​​opening to achieve a limiting position.

[0102] Corresponding to the first snap-fit ​​assembly, the second snap-fit ​​assembly includes a matching second snap-fit ​​element and a second snap-fit ​​opening. The second snap-fit ​​element is disposed on the first mounting element 15, extending from front to back in a protruding form; the second snap-fit ​​interface is disposed on the main mounting portion 17 of the second mounting element 16, and the second snap-fit ​​interface is a through hole extending in the vertical direction. The second snap-fit ​​element can slide within the second snap-fit ​​interface until it abuts against the lower edge of the second snap-fit ​​interface to achieve a limiting position.

[0103] In some embodiments of this application, the first snap-fit ​​component and the second snap-fit ​​component may also be designed as other snap-fit ​​structures.

[0104] After being connected by the first snap-fit ​​assembly and the second snap-fit ​​assembly, the first mounting element 15 and the second mounting element 16, which are snap-fit ​​connected, are further fixed by bolts; the corresponding screw holes can be located on the main mounting part 17 of the second mounting element 16 and the lower edge of the first mounting element 15, respectively.

[0105] In some embodiments of this application, the first mounting element 15 further includes a first body 22. The auxiliary mounting portion 19 of the first mounting element 15 and the first body 22 are continuously and integrally formed, but the auxiliary mounting portion 19 and the first body 22 are not on the same plane to avoid interference during installation. For example, the first body 22 may have a bend, and the first mounting element 15 is formed at one end of the bend.

[0106] In some embodiments of this application, the second mounting element 16 further includes a second body 23. The main mounting portion 17 of the second mounting element 16 and the second body 23 are continuously and integrally formed, but the main mounting portion 17 and the second body 23 are not on the same plane to avoid interference during installation. For example, the second body 23 may have a bend, and the second mounting element 16 is formed at one end of the bend.

[0107] In some embodiments of this application, the first mounting element 15 is disposed relatively close to the outer casing, and the second mounting element 16 is disposed relatively far from the outer casing. The pipe connected to the shut-off valve 27 fixed on the first mounting element 15 can pass between the two shut-off valves 27 fixed on the second mounting element 16, thus avoiding interference between the pipe connected to the shut-off valve 27 and the valve body. In the front-rear direction, the auxiliary mounting part 19, the first main body 22, the main mounting part 17, and the second main body 23 are arranged sequentially.

[0108] In some embodiments of this application, the main body of the second mounting element 16 has an operating opening 24 that extends through the second mounting element 16. An operator's hand or tools can pass through the operating opening 24 to perform installation, maintenance, or debugging. In some embodiments of this application, the operating opening 24 is a rectangular through hole.

[0109] In some embodiments of this application, a limiting hole 25 is also provided on the main body of the first mounting element 15. The mounting assembly 13 also includes a reinforcing element 33, and the limiting hole 25 is used in conjunction with the reinforcing element 33.

[0110] In some embodiments of this application, the limiting hole 25 is an elongated narrow hole. The reinforcing element 33 is generally strip-shaped, continuously integrally formed, and has a bending angle. One end of the reinforcing element 33 can extend into the limiting hole 25 and be snapped in place, while the other end is detachably (e.g., by bolts) fixed to the housing or a frame within the housing. When supporting multiple shut-off valves 27 simultaneously, the reinforcing element 33 can prevent the first mounting element 15 from shaking, especially during transportation, thus improving structural stability.

[0111] In some embodiments of this application, the second mounting element 16 is fixedly disposed on the base plate 14. Specifically, the second body 23 is provided with a first assembly element. The base plate 14 is provided with a second assembly element. The first assembly element and the second assembly element cooperate to mount the second mounting element 16 on the base plate 14.

[0112] In some embodiments of this application, the first mounting element is a tongue-shaped connecting element 26 formed in an opening at the bottom of the second body 23, extending from front to back; the second mounting element is a protruding element 34 formed on the base plate 14, with the tongue-shaped connecting element 26 extending into the protruding element 34 to mount the second mounting element 16 onto the base plate 14. The shape of the protruding element 34 fits tightly with the tongue-shaped connecting element 26, and the contact surface between them can provide sufficient friction to maintain the stable connection of the second mounting element 16. The protruding element 34 may also be fitted with a guide groove and / or a locking structure to aid in alignment and fixation during insertion, and to automatically lock after the tongue-shaped connecting element 26 is inserted to prevent it from falling off. The locking structure can be a mature structure from the prior art, which will not be described in detail here.

[0113] In some embodiments of this application, the refrigerant piping connected to the first interface 28 of the plurality of shut-off valves 27 can pass through the base plate 14 and further connect to the refrigerant piping on the side of the indoor unit of the air conditioner. To accommodate two-pipe, three-pipe, and four-pipe piping systems simultaneously, a large piping connection opening 35 needs to be reserved on the base plate 14. In some embodiments of this application, the piping connection opening 35 is approximately rectangular, its length corresponding to the plurality of shut-off valves 27 arranged along its length; the piping connection opening 35 is located on the front side of the second mounting element 16.

[0114] like Figure 3 ,as well as Figures 9 to 12 As shown, after the refrigerant piping is installed, there will be a certain gap between the piping connection opening 35 and the refrigerant piping. This is especially true because, to allow more refrigerant piping to pass through and to reserve some assembly space, the size of the piping connection opening 35 adapted to two-pipe, three-pipe, and four-pipe systems is designed to be relatively large. This allows rodents or other small animals to enter the outdoor unit of the air conditioner through the piping connection opening 35, posing a risk of chewing cables, damaging components, or nesting inside the casing, leading to air conditioning system malfunctions. To avoid this situation, in some embodiments of this application, a protective element 36 is also provided on the base plate 14.

[0115] In some embodiments of this application, the protective element 36 is mounted on one side of the second mounting element 16, such as the front side.

[0116] In some embodiments of this application, the protective element 36 is a generally plate-shaped component, the length direction of the protective element 36 corresponds to a plurality of shut-off valves 27 arranged along the length direction, and the area of ​​the protective element 36 is larger than the area of ​​the pipeline connection opening 35.

[0117] In some embodiments of this application, one or more protective notches are formed on the protective element 36; the protective notches extend in the length or width direction. The protective notches are correspondingly provided with refrigerant lines. One or more independently provided knockout plates are provided in the protective notches, the knockout plates are correspondingly provided with refrigerant lines, the knockout plates are provided in the protective notches, a pre-cut groove is provided between the knockout plates and the protective notches, the protective notches are located below at least one refrigerant line interface of the shut-off valve 27 installed on the first mounting element 15 and / or the second mounting element 16, and when the knockout plates are removed, the protective notches can communicate with the line connection opening 35.

[0118] In some embodiments of this application, multiple protective notches and several shut-off valves 27 mounted on the main mounting portion 17 are arranged in the same direction.

[0119] In some embodiments of this application, a first protective notch 37 and a second protective notch 38 are formed on the protective element 36. The first protective notch 37 and the second protective notch 38 are arranged sequentially along the length direction of the housing. The first protective notch 37 extends from back to front in a direction substantially parallel to the width direction, and the second protective notch 38 also extends from back to front in a direction substantially parallel to the width direction. The extension distance of the second protective notch 38 is greater than the extension distance of the first protective notch 37, such that the second protective notch 38 is at least partially located below the first interface 28 of the shut-off valve 27 installed in the auxiliary mounting part 19, and the refrigerant pipeline connected to the first interface 28 of this shut-off valve 27 can pass through the second protective notch 38.

[0120] In some embodiments of this application, the protective element 36 includes a first knockdown plate 39 and a second knockdown plate 40. The first knockdown plate 39 and the second knockdown plate 40 are independently disposed. The first knockdown plate 39 is disposed in a first protective notch 37, and the second knockdown plate 40 is disposed in a second protective notch 38. A first pre-cut groove is provided between the first knockdown plate 39 and the first protective notch 37, and a second pre-cut groove is provided between the second knockdown plate 40 and the second protective notch 38. Depending on the number of refrigerant lines in two-pipe, three-pipe, and four-pipe configurations, the first knockdown plate 39 and / or the second knockdown plate 40 can be removed when necessary. The first protective notch 37 and / or the second protective notch 38 communicate with the pipe connection opening 35, ensuring that there are no large gaps in the remaining areas while completing the refrigerant line installation, thus preventing small animals from entering the casing.

[0121] In some embodiments of this application, the depth of the first pre-cut groove is 50%-70% of the thickness of the protective element 36.

[0122] In some embodiments of this application, the depth of the second pre-cut groove is 50% to 70% of the thickness of the protective element 36.

[0123] In some embodiments of this application, the first pre-cut groove penetrates the protective element 36, the first knock-off plate 39 and the first protective notch 37 are connected by a plurality of distributed first connection points.

[0124] In some embodiments of this application, the second pre-cut groove penetrates the protective element 36, the second knock-off plate 40, and the second protective notch 38 are connected by a plurality of distributed second connection points.

[0125] In some embodiments of this application, the first pre-cut groove and the second pre-cut groove partially overlap.

[0126] In some embodiments of this application, a protective notch is formed on the protective element 36, extending in both the length and width directions, and is located below the first interface 28 of the shut-off valve 27 installed in the main mounting portion 17 and the auxiliary mounting portion 19. The protective element 36 further includes a first knock-out plate 39, a second knock-out plate 40, a third knock-out plate 41, and a fourth knock-out plate 42. The third knock-out plate 41, the fourth knock-out plate 42, the fifth knock-out plate 43, and the sixth knock-out plate 44 are independently disposed; the third knock-out plate 41, the fourth knock-out plate 42, the fifth knock-out plate 43, and the sixth knock-out plate 44 are disposed within the protective notch. Pre-cut grooves are provided between the third knock-out plate 41, the fourth knock-out plate 42, the fifth knock-out plate 43, and the sixth knock-out plate 44 and the protective notch, and between the third knock-out plate 41, the fourth knock-out plate 42, the fifth knock-out plate 43, and the sixth knock-out plate 44. Depending on the number of refrigerant lines in two-pipe, three-pipe, and four-pipe configurations, one or more of the third knockdown plate 41, fourth knockdown plate 42, fifth knockdown plate 43, and sixth knockdown plate 44 can be removed when necessary. This ensures that there are no large gaps in the remaining areas while completing the refrigerant line installation, preventing small animals from entering the casing.

[0127] In some embodiments of this application, the depth of the pre-cut groove is 50%-70% of the thickness of the protective element 36.

[0128] In some embodiments of this application, the pre-cut groove passes through the protective element 36, and the third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43 and the sixth knockdown plate 44 are connected to the protective notch, and the third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43 and the sixth knockdown plate 44 are connected by a number of distributed connection points.

[0129] In some embodiments of this application, circular openings are also formed on the third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43, and / or the sixth knockdown plate 44. A circular knockdown element 45 is disposed within the circular opening, and a pre-cut circular groove is formed between the circular knockdown element 45 and the circular opening. When the refrigerant line is relatively thin, only the circular knockdown element 45 can be removed to reduce the gap between it and the refrigerant line. The depth of the pre-cut circular groove can be 50%-70% of the thickness of the protective element 36, or it can penetrate the protective element 36 and be connected to the circular opening through several connection points.

[0130] In some embodiments of this application, concentric circular openings are formed on the first knockdown plate 39, the second knockdown plate 40, the third knockdown plate 41, and / or the fourth knockdown plate 42; a circular knockdown element 45 is disposed in the central circular opening, and an annular knockdown element 46 is disposed in the circular openings near the periphery; pre-cut circular grooves are formed between the circular knockdown element 45 and the circular opening, and between the annular knockdown element 46 and the circular opening. Therefore, depending on the diameter of the refrigerant pipeline, the annular knockdown element 46 and the circular knockdown element 45 can be selected and removed, or only the central circular knockdown element 45 can be removed, achieving a more flexible installation method. The depth of the pre-cut circular groove can be 50%-70% of the thickness of the protective element 36, or it can penetrate the protective element 36 and be connected to the circular opening through several connection points.

[0131] In some embodiments of this application, at least one edge of the protective element 36 extends downward in a direction substantially perpendicular to the plane of the knockdown plate, thereby ensuring that the protective element 36 has a certain structural strength after the knockdown plate is removed, and will not bend or break.

[0132] In some embodiments of this application, the front edge of the protective element 36 extends downward in a direction generally perpendicular to the plane of the knock-off plate, and then extends forward in a direction generally parallel to the plane of the base plate 14 to form a tongue-shaped connecting end 47; the tongue-shaped connecting end 47 can be detachably fixed to the base plate 14.

[0133] In some embodiments of this application, one of the two side edges of the protective element 36 extends downward at a certain angle to the plane where the knock-off plate is located, to form an outwardly extending reinforcing connection 48. The reinforcing connection 48 can extend into a through hole opened on the base plate 14 and interfere with the base plate 14 to restrict the movement of the protective element, thereby further strengthening the fixation of the protective element.

[0134] like Figure 1 as well as Figures 13 to 19 As shown, in some embodiments of this application, the outdoor heat exchanger 10 is mounted on the side of the base plate 14. The outdoor heat exchanger 10 includes a first heat exchange section 49 and a second heat exchange section 50. The first heat exchange section 49 and the second heat exchange section 50 are arranged symmetrically.

[0135] The first heat exchange section 49 includes a continuous first distal portion 51 and a first proximal portion 52, the connection between the first distal portion 51 and the first proximal portion 52 being located at one corner of the housing; the end of the first distal portion 51 extends to form a first distal end portion 54, the end of the first proximal portion 52 extends to form a first proximal end portion, the connection between the first proximal portion 52 and the first proximal end portion being located at another corner of the housing; the first distal end portion 54, the first distal portion 51, the first proximal portion 52 and the first proximal end portion together form a generally G-shaped region; the height of the first heat exchange section 49 is approximately the same as the height of the mounting cavity 12 to provide sufficient heat exchange area.

[0136] The second heat exchange section 50 includes a continuous second distal section and a second proximal section, the connection of which is located at another corner of the housing. The first distal section 51 and the second distal section are disposed adjacent to each other. The end of the second distal section extends to form a second distal end portion 53, and the end of the second proximal section extends to form a second proximal end portion. The connection of the second proximal section and the second proximal end portion is located at another corner of the housing. The second distal end portion 53, the second distal section, the second proximal section, and the second proximal end portion together form another generally G-shaped region. The height of the second heat exchange section 50 is approximately the same as the height of the mounting cavity 12 to provide sufficient heat exchange area. The first distal end portion 54 and the second proximal end portion are disposed adjacent to each other and located at the center of the housing.

[0137] For the installation of the first heat exchange section 49 and the second heat exchange section 50, the outdoor unit of the air conditioner also includes a remote connecting element, a central connecting element 55 and a bottom connecting element 56.

[0138] In some embodiments of this application, the outdoor heat exchanger 10 further includes a first connecting end plate and a second connecting end plate. The first connecting end plate is disposed outside the first distal end 54, and the heat exchange tubes of the first heat exchange section 49 pass through the first connecting end plate. The second connecting end plate is disposed outside the second distal end 53, and the heat exchange tubes of the second heat exchange section 50 pass through the second connecting end plate. A distal connecting element is disposed between the first connecting end plate and the second connecting end plate, and is detachably fixedly connected to the first connecting end plate and the second connecting end plate.

[0139] A central connecting element 55 is provided on the front side of the distal connecting element. Eaves plates are symmetrically arranged on both sides of the central connecting element 55.

[0140] The bottom connecting element 56 is located in front of the central connecting element 55, and the bottom connecting element 56 is provided with a bent portion that connects to the base plate 14. The bottom connecting element 56 and the base plate 14 are detachably fixedly connected by bolts.

[0141] In some embodiments of this application, the distal connecting element includes a first distal connecting element 57 and a second distal connecting element 58. The first distal connecting element 57 and the second distal connecting element 58 are arranged vertically to provide sufficient structural strength for the connection.

[0142] The first and second proximal ends are detachably fixed to a bracket inside the housing.

[0143] The outdoor heat exchanger 10 can be installed as a whole. First, the first heat exchange section 49 and the second heat exchange section 50 are connected using the far-side connecting element and the center connecting element 55 to form a double G-shaped structure. Then, the double G-shaped outdoor heat exchanger 10 connected as a whole is pushed horizontally above the base plate 14 along a direction parallel to the base plate 14, so that the outdoor heat exchanger 10 is arranged around the outer shell. After being pushed into place, the bottom connecting element 56 is fixed in front of the center connecting element 55, and the first proximal end and the second proximal end are fixed to the bracket inside the outer shell.

[0144] In some embodiments of this application, the base plate 14 includes a first bottom support 59 and a second bottom support 60, which together form the base plate 14. A connecting cavity 63 is formed between the first bottom support 59 and the second bottom support 60. A first heat exchange section 49 is located above the first bottom support 59, and a second heat exchange section 50 is located above the second support section. The bottom connecting element 56 has a symmetrically arranged first bending section 61 and second bending section 62. The first bending section 61 is detachably fixedly connected to the first bottom support 59, and the second bending section 62 is detachably fixedly connected to the second bottom support 60.

[0145] When the piping inside the outdoor unit of an air conditioner is complex, such as a four-pipe design, integral installation becomes difficult. To solve this problem, the outdoor unit also includes a first limiting element 64 and a second limiting element 65. One of the first limiting element 64 and the second limiting element 65 is used to position the installation of the first heat exchanger 49, and the other is used to position the installation of the second heat exchanger 50.

The positioning part 66 extends in the width direction in the shape of a flat plate, and an angle is formed between the positioning part 66 and the first connecting part 67. The first connecting part 67 extends obliquely downward, and the second connecting part 68 extends vertically downward. The tail end of the second connecting part 68 is bent.

[0147] The second limiting element 65 includes a first wall portion 69, a second wall portion 70, and a third wall portion 71; the first wall portion 69, the second wall portion 70, and the third wall portion 71 are continuous and form a downward-opening positioning cavity 72; wherein the first wall portion 69 and the third wall portion 71 extend in the width direction, and a plurality of positioning rectangular holes 73 are provided on the first wall portion 69 and / or the third wall portion 71. The second limiting element 65 also includes a connecting bend 74, which extends downward from the third wall portion 71, and the connecting bend 74 can be detachably and fixedly connected to the side of the first bottom support member 59.

[0148] The first limiting element 64 and the second limiting element 65 work together. The first connecting portion 67 of the first limiting element 64 extends into one of the positioning rectangular holes 73 and extends downward at an angle until the second connecting portion 68 extends out from the downward opening of the positioning cavity 72. The second connecting portion 68 and the bend at its tail end extend into the connecting cavity 63 and fit into the edge of the first bottom support member 59 to form a stable connection. The first limiting element 64 and the second limiting element 65 are located behind the central connecting element 55.

[0149] With the assistance of the first limiting element 64 and the second limiting element 65, the first heat exchange part 49 and the second heat exchange part 50 can be installed separately.

[0150] First, the first distal connecting element 57 and the second distal connecting element 58 are detachably and fixedly connected to the first distal end 54, and the central connecting element 55 is detachably and fixedly connected to the second distal end 53.
