[0055] The following description will be made with reference to the accompanying drawings Figures 1 to 19 The embodiments of the air conditioner outdoor unit provided by the present application are described.

[0056] The air conditioner outdoor unit is a component of an air conditioning system.

[0057] The air conditioning system performs a refrigeration cycle of the air conditioning system by using the compressor 11, the condenser, the throttling element, and the evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat the indoor space.

[0058] The low-temperature and low-pressure refrigerant enters the compressor 11, which compresses the refrigerant gas into a high-temperature and high-pressure state 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.

[0059] The throttling element (for example, an electronic expansion valve) expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the electronic expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 11. The evaporator can achieve a refrigeration effect by exchanging heat with the material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioning system can adjust the temperature of the indoor space.

[0060] The air conditioner outdoor unit refers to the part of the refrigeration cycle including the compressor 11 and the outdoor heat exchanger, and the air conditioner indoor unit includes the indoor heat exchanger, and the electronic expansion valve can be provided in the indoor unit or the outdoor unit.

[0061] The indoor heat exchanger and the outdoor heat exchanger are used as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in a heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0062] The air conditioner outdoor unit includes a housing in the shape of a generally rectangular box. The housing is made of a steel plate (for example, a galvanized steel plate) or other metal materials, has corrosion resistance, durability, and sufficient strength. The housing is used to protect the internal components from the external environment (such as wind, rain, dust, etc.), prevent impurities (such as leaves, etc.) in the air from entering the interior, and maintain the long-term stable operation of the air conditioner outdoor unit.

[0063] In some embodiments of the present application, the housing can be provided with ventilation holes, grilles, or fins to ensure that the outdoor heat exchanger 10 installed therein can achieve an ideal heat dissipation efficiency. The bottom of the housing is provided with a bracket or a mounting hole for fixing the air conditioner outdoor unit to the wall surface, platform, or other bracket to ensure stable installation and withstand the vibration during operation.

[0064] An installation cavity 12 is formed in the housing. The compressor 11, the outdoor heat exchanger 10, the outdoor fan, the stop valve 27, the piping, and other components are arranged in the installation cavity 12.

[0065] The shell includes a bottom plate 14. In some embodiments of the present application, the shell also includes a top plate, two side plates, a front plate and a rear plate, which together enclose an installation cavity 12 in the shell. In some embodiments of the present application, the bottom plate 14 is a substantially rectangular metal plate-shaped component, constituting the bottom portion of the installation cavity 12. The compressor 11 is installed on the bottom plate 14. The bottom plate 14 provides support for the compressor 11, and also plays a protective and damping role. In the following description, as long as there is no special description, the front face as shown in the figure is taken as the reference, where "up" and "down" are the directions in the height direction of the shell, "left" and "right" are the directions in the length direction of the shell, and "front" and "rear" are the directions in the width direction of the shell. Figure 2

[0066] In some embodiments of the present application, the compressor 11 is installed in the central region of the bottom plate 14, and the compressor 11 is fixedly connected to the bottom plate 14 to avoid vibration or displacement during operation.

[0067] In some embodiments of the present application, the outdoor heat exchanger 10 is installed on the side of the bottom plate 14, so that the outdoor heat exchanger 10 can efficiently exchange heat with external air.

[0068] A stop valve 27 is also provided in the shell, which is installed between the high-pressure side and the low-pressure side of the refrigeration cycle, and is used to control the flow of refrigerant.

[0069] In some embodiments of the present application, the number of stop valves 27 in the shell is two. The layout of the stop valves 27 matches the two-pipe refrigeration cycle. The two-pipe refrigeration cycle is the most common air conditioning pipe configuration, in which the air conditioning outdoor unit and the air conditioning indoor unit are connected through liquid-side piping and gas-side piping. Correspondingly, the stop valves 27 include a liquid-side stop valve 27 and a gas-side stop valve 27, the liquid-side stop valve 27 is provided on the liquid-side piping, and the gas-side stop valve 27 is provided on the gas-side piping.

[0070] In some embodiments of the present application, in order to increase flexibility, the air conditioning outdoor unit and the air conditioning indoor unit can also be connected through three pipes. The layout of the stop valves 27 matches the three-pipe refrigeration cycle, and one corresponding stop valve 27 is provided on each pipe. The three-pipe refrigeration cycle can be used in cold and hot dual-use environments, and can simultaneously meet the refrigeration demand and the heating demand.

[0071] In some embodiments of the present application, in order to cope with more complex use environments, the air conditioning outdoor unit and the air conditioning indoor unit can also be connected through four pipes. The layout of the stop valves 27 matches the four-pipe refrigeration cycle, and one corresponding stop valve 27 is provided on each pipe. The four-pipe refrigeration cycle can simultaneously realize refrigeration and heating, and can also ensure that the cold and heat demands of different regions are simultaneously met.​

[0079] As shown in the drawings, the first mounting element 15 and the second mounting element 16 are introduced as examples of plate-shaped.

[0080] The first mounting element 15 and the second mounting element 16 extend in a direction substantially parallel to the length direction.

[0081] In some embodiments of the present application, the second mounting element 16 has a main mounting portion 17, which is located substantially at the upper edge of the second mounting element 16, and the main mounting portion 17 can install several stop valves 27 in the form of being arranged along the same direction (e.g. the length direction).

[0082] In some embodiments of the present application, one refrigerant interface of the stop valve 27 is located at one side of the second mounting element 16, and the other refrigerant interface is located at the other side of the second mounting element 16; for example, the first interface 28 of the stop valve 27 connected with the refrigerant pipe near the indoor unit is located at the front side of the second mounting element 16, and the second interface 29 connected with the refrigerant pipe near the outdoor unit is located at the rear side of the second mounting element 16, so that the operating end portion 30 is located at a relatively forward position and is in a relatively protruding state, which is convenient for operation; that is, the stop valve 27 is installed on the second mounting element 16 in the form that the operating end portion 30 is forward and the second interface 29 connected with the refrigerant pipe near the outdoor unit penetrates through.

[0093] In some embodiments of the present application, the two main installation notches 18 have the same height, and the other main installation notch 18 has a different height.

[0094] When applied to a two-pipe or three-pipe air conditioning system, only the second installation element 16 can be used, that is, the installation requirements of two or three stop valves 27 can be met. The second installation element 16 can also be used to install part of the stop valves 27, and the first installation element 15 can be used to install the other part of the stop valves 27, so that the layout in the shell is more flexible.

[0104] In some embodiments of the present application, the first clamping assembly and the second clamping assembly can also be designed as other forms of clamping structures.

[0105] After being connected by the first clamping assembly and the second clamping assembly, the first mounting element 15 and the second mounting element 16 connected by clamping are further fixed by bolts; corresponding screw holes can be respectively located on the main mounting portion 17 of the second mounting element 16 and the lower edge of the first mounting element 15.

[0106] In some embodiments of the present application, the first mounting element 15 further comprises a first main body 22, and the auxiliary mounting portion 19 and the first main body 22 of the first mounting element 15 are continuously and integrally formed, but the auxiliary mounting portion 19 and the first main body 22 of the first mounting element 15 are not in the same plane to avoid interference during installation. For example, the first main body 22 can have a bend, and the first mounting element 15 is formed at one end of the bend.

[0107] In some embodiments of the present application, the second mounting element 16 further comprises a second main body 23, and the main mounting portion 17 and the second main body 23 of the second mounting element 16 are continuously and integrally formed, but the main mounting portion 17 and the second main body 23 of the second mounting element 16 are not in the same plane to avoid interference during installation. For example, the second main body 23 can have a bend, and the second mounting element 16 is formed at one end of the bend.

[0108] In some embodiments of the present application, the first mounting element 15 is arranged relatively close to the shell, the second mounting element 16 is arranged relatively far from the shell, and the pipeline connected with the stop valve 27 fixed on the first mounting element 15 can pass between the two stop valves 27 fixed on the second mounting element 16, avoiding interference between the pipeline connected with the stop valve 27 and the valve body. In the front-back direction, the auxiliary mounting portion 19, the first main body 22, the main mounting portion 17 and the second main body 23 are arranged in sequence.

[0109] In some embodiments of the present application, the main body of the second mounting element 16 is provided with an operation opening 24, which penetrates the second mounting element 16. The hand of an operator or a tool can pass through the second mounting element 16 from the operation opening 24 to perform installation, maintenance or debugging. In some embodiments of the present application, the operation opening 24 is a rectangular through hole.

[0110] In some embodiments of the present application, the main body of the first mounting element 15 is further provided with a limiting hole 25. The mounting assembly 13 further comprises a reinforcing element 33, and the limiting hole 25 is used in cooperation with the reinforcing element 33.

[0111] In some embodiments of the present 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 be inserted into the limiting hole 25 and clamped and fixed, and the other end can be detachably (for example, by a bolt) fixed on the shell or a frame in the shell. When supporting multiple stop valves 27 at the same time, the reinforcing element 33 can avoid the first mounting element 15 from shaking, especially during transportation, and improve the structural stability.

[0112] In some embodiments of the present application, the second mounting element 16 is fixedly arranged on the bottom plate 14. Specifically, the second main body 23 is provided with a first assembly element. The bottom 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 bottom plate 14.

[0113] In some embodiments of the present application, the first assembly element is a tongue-shaped connecting element 26 formed in an opening at the bottom of the second main body 23, which extends from front to back; and the second assembly element is a protruding element 34 formed on the bottom plate 14, and the tongue-shaped connecting element 26 is inserted into the protruding element 34 to mount the second mounting element 16 on the bottom plate 14. The shape of the protruding element 34 closely matches the tongue-shaped connecting element 26, and the contact surface therebetween can provide sufficient friction to keep the second mounting element 16 connected stably. The protruding element 34 can be further provided with a guide groove and / or a locking structure inside to help alignment and fixation during insertion and to be automatically locked after the tongue-shaped connecting element 26 is inserted to prevent falling off. The locking structure can be selected from the mature structures in the prior art, which will not be described here.

[0114] In some embodiments of the present application, the refrigerant pipe connected with the first interface 28 of the plurality of stop valves 27 can pass through the bottom plate 14 and further connected with the refrigerant pipe on one side of the air conditioner indoor unit. In order to match the two-pipe, three-pipe and four-pipe system, a larger pipe connection opening 35 needs to be reserved on the bottom plate 14. In some embodiments of the present application, the pipe connection opening 35 is generally rectangular, and the length direction corresponds to the plurality of stop valves 27 arranged along the length direction; the pipe connection opening 35 is located on the front side of the second mounting element 16.

[0115] As shown in Figure 3 , and Figures 9 to 12 After the refrigerant pipe is installed, there will be a certain gap between the pipe connection opening 35 and the refrigerant pipe, especially in order to allow more refrigerant pipes to pass through and need to reserve a certain assembly space, and the size of the pipe connection opening 35 that matches the two-pipe, three-pipe and four-pipe system will be designed to be relatively large. This makes it possible for rodents or other small animals to enter the air conditioner outdoor unit from the pipe connection opening 35, which may cause the risk of damaging the cable, damaging the parts or nesting inside the shell, resulting in the failure of the air conditioning system. In order to avoid this situation, in some embodiments of the present application, the bottom plate 14 is also provided with a protection element 36.

[0116] In some embodiments of the present application, the protection element 36 is installed on the front side of the second mounting element 16.

[0117] In some embodiments of the present application, the protection element 36 is a generally plate-shaped component, the length direction of the protection element 36 corresponds to the plurality of stop valves 27 arranged along the length direction, and the area of the protection element 36 is greater than the area of the pipe connection opening 35.

[0118] In some embodiments of the present application, one or more notches are formed on the protection element 36; the notches extend in the length direction or the width direction; one or more independently arranged knock-off plates are arranged in the notches; a pre-cut groove is arranged between the knock-off plate and the notch; and the notch is located below at least one refrigerant pipe interface of the stop valve 27 installed on the first mounting element 15 and / or the second mounting element 16.

[0119] In some embodiments of the present application, the protective element 36 is provided with a first gap 37 and a second gap 38. The first gap 37 and the second gap 38 are arranged in sequence in the length direction of the shell. The first gap 37 extends from back to front along a direction substantially parallel to the width direction, and the second gap 38 also extends from back to front along a direction substantially parallel to the width direction. The extension distance of the second gap 38 is greater than that of the first gap 37, so that the second gap 38 is at least partially located below the first interface 28 of the stop valve 27 mounted on the auxiliary mounting portion 19, and the refrigerant pipeline connected with the first interface 28 of the stop valve 27 can pass through the second gap 38.

[0120] In some embodiments of the present application, the protective element 36 comprises a first knock-off plate 39 and a second knock-off plate 40. The first knock-off plate 39 and the second knock-off plate 40 are independently arranged. The first knock-off plate 39 is arranged in the first gap 37, and the second knock-off plate 40 is arranged in the second gap 38. A first pre-cut groove is arranged between the first knock-off plate 39 and the first gap 37, and a second pre-cut groove is arranged between the second knock-off plate 40 and the second gap 38. According to different numbers of refrigerant pipelines of two-pipe system, three-pipe system and four-pipe system, the first knock-off plate 39 and / or the second knock-off plate 40 can be removed when needed, so as to ensure that there is no large gap in the remaining area after the refrigerant pipeline is installed, and to avoid small animals from entering the shell.

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

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

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

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

[0126] In some embodiments of the present application, the protective element 36 is formed with a notch extending in the length direction and the width direction, which is located below the first interface 28 of the stop valve 27 installed on the main mounting portion 17 and the auxiliary mounting portion 19. The protective element 36 further comprises a first knock-off plate 39, a second knock-off plate 40, a third knock-off plate 41, and a fourth knock-off plate 42. The third knock-off plate 41, the fourth knock-off plate 42, a fifth knock-off plate 43, and a sixth knock-off plate 44 are independently arranged; the third knock-off plate 41, the fourth knock-off plate 42, the fifth knock-off plate 43, and the sixth knock-off plate 44 are arranged in the notch. A pre-cut groove is arranged between the third knock-off plate 41, the fourth knock-off plate 42, the fifth knock-off plate 43, and the sixth knock-off plate 44 and the notch, and between the third knock-off plate 41, the fourth knock-off plate 42, the fifth knock-off plate 43, and the sixth knock-off plate 44. According to the number of different refrigerant pipelines of two-tube, three-tube, and four-tube, one or more of the third knock-off plate 41, the fourth knock-off plate 42, the fifth knock-off plate 43, and the sixth knock-off plate 44 can be removed as needed, to ensure that the remaining area does not have a large gap, and to avoid small animals entering the shell.

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

[0128] In some embodiments of the present application, the pre-cut groove penetrates the protective element 36, and the third knock-off plate 41, the fourth knock-off plate 42, the fifth knock-off plate 43, and the sixth knock-off plate 44 are connected through a plurality of distributed connection points between the third knock-off plate 41, the fourth knock-off plate 42, the fifth knock-off plate 43, and the sixth knock-off plate 44 and the notch.

[0129] In some embodiments of the present application, a circular opening is further formed on the third knock-off plate 41, the fourth knock-off plate 42, the fifth knock-off plate 43, and / or the sixth knock-off plate 44. A circular knock-off element 45 is arranged in the circular opening, and a pre-cut circular groove is formed between the circular knock-off element 45 and the circular opening. When the refrigerant pipeline is relatively thin, only the circular knock-off element 45 can be removed to make the gap between the refrigerant pipeline smaller. The depth of the pre-cut circular groove can be 50%-70% of the thickness of the protective element 36, or the pre-cut circular groove can penetrate the protective element 36 and be connected with the circular opening through a plurality of 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 limit the movement of the protective plate, thereby further strengthening the fixation of the protective plate.
