Description

Technical Field

[0001] This invention relates to the field of compressor technology, and in particular to a horizontal compressor and air conditioner that can be mounted on the ceiling or wall. Background Technology

[0002] Currently, for automotive air conditioners, in order to reduce the overall height of the vehicle body and the overall size of the outdoor unit, air conditioners are typically designed as either roof-mounted or wall-mounted. Roof-mounted air conditioners have a horizontal compressor installed on the roof, while wall-mounted air conditioners have a vertical compressor installed on one side of the vehicle body. These two different installation methods can meet the different needs of automotive manufacturers and end users, facilitating the installation of automotive air conditioners.

[0003] However, the structures of top-mounted horizontal compressors and wall-mounted vertical compressors differ significantly. The piping used to form a closed refrigerant circulation loop requires customization based on the specific compressor, increasing design and manufacturing costs. Furthermore, each requires separate molds for the air conditioner casing, leading to higher costs. Additionally, the materials used are not interchangeable, necessitating separate material management for each system, further increasing material management expenses. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to overcome the shortcomings of the prior art and provide a horizontal compressor that can be mounted on the roof or wall, which can be applied to air conditioners with two different structures, effectively improving the applicability of the horizontal compressor that can be mounted on the roof or wall.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A horizontal compressor that can be mounted on the top or wall includes a compressor housing, a pump body structure, mounting brackets, a liquid receiver, a suction pipe, and an exhaust pipe. The compressor housing has an end cover and a protective cover at both ends along its axial direction. The end face where the end cover is located is an imaginary front face. The pump body structure is coaxially built into the compressor housing. The mounting brackets are located at the bottom outer side of the compressor housing. The connection surface between the mounting brackets and the compressor housing is an imaginary bottom surface. The axis of the compressor housing is perpendicular to the imaginary bottom surface, forming an imaginary vertical plane.

[0007] The pump body structure is provided with a slider groove in the radial direction. The slider groove is located in the lower right area of ​​the imaginary front. The angle formed by the imaginary extension line of the slider groove along its length direction and the imaginary vertical plane is α, where 25° < α < 50°.

[0008] The pump body structure is connected to a pump oil pipe at one end adjacent to the end cover. The pump oil pipe is arranged radially along the pump body structure, and the pipe opening is located in the lower right region of the imaginary front. The angle formed by the imaginary extension line of the pump oil pipe along the radial direction of the pump body structure and the imaginary vertical plane is δ, where 10° < δ < 65°.

[0009] The liquid reservoir is disposed on the outer wall of the compressor housing, and the liquid reservoir is located in the right side region of the imaginary front; the liquid reservoir is connected to the pump body structure through the suction pipe, and the angle formed by the axis of the section of the suction pipe connected to the pump body structure and the imaginary vertical plane is β, 18°<β<25°.

[0010] The exhaust pipe is connected to the outer wall of the compressor housing and is located in the upper left area of ​​the imaginary front; the angle formed by the axis of the section of the exhaust pipe connected to the compressor housing and the imaginary vertical plane is γ, where 25° < γ < 50°.

[0011] In one embodiment, a connecting frame is provided on the outer wall of the compressor housing, and the liquid reservoir is disposed on the connecting frame.

[0012] In one embodiment, the number of mounting brackets is two, and the two mounting brackets are distributed at an axial distance along the bottom outer side of the compressor housing.

[0013] In one embodiment, a pump oil cover is coaxially provided at one end of the pump body structure adjacent to the end cover, and one end of the pump oil pipe is connected through the pump oil cover.

[0014] In one embodiment, the pump body structure includes a bearing flange coaxially arranged, the outer peripheral wall of the bearing flange being connected to the inner peripheral wall of the compressor housing; the bearing flange is provided with a vent hole through it along its axial direction, the vent hole being located in the upper half of the compressor housing.

[0015] In one embodiment, the vent hole and the exhaust pipe are located on the same side of an imaginary vertical plane, and the angle formed by the line connecting the center of the vent hole and the center line of the pump body structure with the imaginary vertical plane is less than 10°.

[0016] In one embodiment, the vent and the suction pipe are located on the same side of an imaginary vertical plane, and the angle formed by the line connecting the center of the vent and the center line of the pump body structure with the imaginary vertical plane is less than 40°.

[0017] In one embodiment, the bearing flange has an oil passage hole extending through it along its axial direction, and the oil passage hole is located in the lower half of the compressor housing; the diameter of the oil passage hole is d, and the outer diameter of the bearing flange is D, where 0.05 < d / D < 0.16.

[0018] As one implementation method, the mounting bracket has mounting holes.

[0019] Therefore, the horizontal compressor that can be mounted on the roof or wall, provided by the embodiments of the present invention, improves the pump body structure and compressor housing so that it can be applied to air conditioners with both roof-mounted and wall-mounted structures. For example, when applied to a roof-mounted air conditioner, the mounting brackets at the bottom of the compressor housing are horizontally assembled. In this case, since the slider groove and the oil pump pipe inlet are located in the lower right region of the compressor housing, and the vent and exhaust pipe are located in the upper left region of the compressor housing, the refrigerant enters the pump body structure from the receiver and drives the pump body structure to operate. The high-pressure refrigerant gas discharged from the pump body structure circulates inside the compressor housing, passes through the vent in the upper left region, and is discharged from the exhaust pipe in the upper left region. This creates a high pressure difference between the cavities on both sides of the pump body structure, allowing the oil pump pipe to perform normal oil pumping operations and achieve lubrication of the internal structure. When the horizontal compressor of this embodiment is applied to a wall-mounted air conditioner, rotating it 90° clockwise from a hypothetical frontal view allows the mounting surface of the mounting bracket away from the compressor housing to be parallel to the vertical plane, facilitating vertical assembly of the mounting bracket. At this time, the slider groove and the oil pump pipe opening are located in the lower left area of ​​the compressor housing, while the vent and exhaust pipe are located in the upper right area of ​​the compressor housing. The oil level inside the compressor housing can still submerge the oil pump pipe opening, allowing the oil pump pipe to still perform normal oil pumping operations. In other words, by improving the slider groove, vent hole, and oil pump pipe of the oil pump structure, as well as the exhaust pipe and liquid receiver, the embodiments of the present invention enable the horizontal compressor of the present invention, which can be mounted on the roof or wall, to be used in air conditioners with both roof-mounted and wall-mounted installation methods. As a result, manufacturers do not need to design two different compressors for air conditioners with two different installation methods, which can effectively reduce design costs, material management costs, and other expenses, and effectively improve the applicability of the horizontal compressor of the present invention.

[0020] In addition, embodiments of the present invention also provide an air conditioner, which includes a horizontal compressor that can be mounted on the ceiling or wall-mounted as described in any of the above embodiments. By improving the design of the slider groove, vent, and oil pump pipe of the oil pump structure, as well as the design of the exhaust pipe and liquid receiver, embodiments of the present invention enable the air conditioner to be suitable for both ceiling-mounted and wall-mounted installation methods, thereby effectively improving the applicability of the air conditioner.

[0031] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention.

[0032] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "left," "right," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting this invention.

[0033] In related technologies, horizontal compressors that can be top-mounted or wall-mounted are installed horizontally, resulting in a low overall height. The bottom area of ​​the internal space houses the oil pump mechanism, and to ensure pumping functionality, the oil pump pipes are typically arranged vertically downwards. Furthermore, to ensure sufficient oil supply to the slider in the pump body, the slider groove in the pump body cylinder is generally oriented perpendicular to the bottom surface. During operation, low-pressure refrigerant gas is drawn in through the suction pipe of the receiver, compressed into high-temperature, high-pressure gas by the pump body structure, and then discharged towards the motor side inside the compressor housing. A high-pressure chamber is formed at the location of the motor rotor. The high-temperature, high-pressure refrigerant gas is discharged from the upper through-hole of the bearing and the gap between the flange and the housing into the low-pressure chamber between the oil pump cover and the compressor housing, and finally discharged through the exhaust pipe. A certain pressure difference can be formed between the high-pressure and low-pressure chambers, thus creating differential oil supply. Oil is supplied from the lower part of the housing to the various friction surfaces of the pump body through the oil pump pipe, ensuring long-term stable operation of the compressor.

[0034] Please also refer to Figures 1 to 5 This embodiment provides a horizontal compressor that can be mounted on the top or wall, including a compressor housing 10, a pump body structure 20, mounting brackets 11, a liquid receiver 30, a suction pipe 31, and a discharge pipe 40. The compressor housing 10 is provided with an end cover 12 and a protective cover 13 at both ends along its axial direction. The end face of the end cover 12 is an imaginary front face. The pump body structure 20 is coaxially built into the compressor housing 10. The mounting brackets 11 are located at the bottom outer side of the compressor housing 10. The connection surface between the mounting brackets 11 and the compressor housing 10 is an imaginary bottom surface. The axis of the compressor housing 10 is perpendicular to the imaginary bottom surface to form an imaginary vertical surface.

[0035] The pump body structure 20 is provided with a slider groove 21 in the radial direction. The slider groove 21 is located in the lower right area of ​​the imaginary front. The angle formed by the imaginary extension line of the slider groove 21 along its length direction and the imaginary vertical plane is α, where 25° < α < 50°.

[0036] The pump body structure 20 is connected to a pump oil pipe 22 at one end adjacent to the end cover 12. The pump oil pipe 22 is arranged radially along the pump body structure 20, and the pipe opening of the pump oil pipe 22 is located in the lower right region of the imaginary front. The angle formed by the imaginary extension line of the pump oil pipe 22 along the radial direction of the pump body structure 20 and the imaginary vertical plane is δ, where 10° < δ < 65°.

[0037] The liquid reservoir 30 is disposed on the outer side wall of the compressor housing 10, and the liquid reservoir 30 is located in the right side region of the imaginary front; the liquid reservoir 30 is connected to the pump body structure 20 through the suction pipe 31, and the angle formed by the axis of the section of the suction pipe 31 connected to the pump body structure 20 and the imaginary vertical plane is β, 18°<β<25°.

[0038] The exhaust pipe 40 is connected to the outer wall of the compressor housing 10, and the exhaust pipe 40 is located in the upper left area of ​​the imaginary front; the angle formed by the axis of the section of the exhaust pipe 40 connected to the compressor housing 10 and the imaginary vertical plane is γ, 25° < γ < 50°.

[0039] like Figure 4 and 5 As shown, the pump body structure 20 of this embodiment includes a bearing flange 23 coaxially arranged, the outer peripheral wall of the bearing flange 23 being connected to the inner peripheral wall of the compressor housing 10; the bearing flange 23 has a vent hole 24 extending through it along its axial direction, the vent hole 24 being located in the upper half of the compressor housing 10. The vent hole 24 and the exhaust pipe 40 are located on the same side of an imaginary vertical plane, and the angle formed by the line connecting the center of the vent hole 24 and the centerline of the pump body structure 20 with the imaginary vertical plane is less than 70°; or, the vent hole 24 and the suction pipe 31 are located on the same side of an imaginary vertical plane, and the angle formed by the line connecting the center of the vent hole 24 and the centerline of the pump body structure 20 with the imaginary vertical plane is less than 40°.

[0040] In addition, such as Figure 4 and 5 As shown, the bearing flange 23 of this embodiment of the invention has an oil passage hole 25 extending through it along its axial direction. The oil passage hole 25 is located in the lower half of the compressor housing 10. The diameter of the oil passage hole 25 is d, and the outer diameter of the bearing flange 23 is D, where 0.05 < d / D < 0.16.

[0041] like Figure 2As shown, one end of the pump body structure 20 is spaced apart from the end cover 12 and forms a low-pressure chamber, with the pump oil pipe 22 located in the low-pressure chamber; the other end of the pump body structure 20 is spaced apart from the protective cover 13 and forms a high-pressure chamber. The refrigerant outlet of the pump body structure 20 is located in the lower half of the compressor housing 10 and discharges towards the high-pressure chamber. In this way, the high-temperature and high-pressure refrigerant gas discharged from below the pump oil structure 20 circulates through the high-pressure chamber, then enters the low-pressure chamber through the vent hole 24 on the bearing flange 23, and is discharged to the outside through the exhaust pipe 40. During this process, a certain pressure difference can be formed between the high-pressure chamber and the low-pressure chamber, thereby forming a pressure difference oil supply. The oil is supplied from the lower part of the compressor housing 10 to each friction surface of the pump body structure 20 through the pump oil pipe 22, ensuring that the horizontal compressor, which can be mounted on the top or wall, can maintain long-term stable operation.

[0042] In some alternative embodiments, the number of vent holes 24 on the bearing flange 23 may be three or four. Furthermore, the shape of the vent holes 24 may be circular, elliptical, or other shapes.

[0043] In some alternative embodiments, the number of oil passage holes 25 may be one or two. Furthermore, the diameter d of the oil passage hole 25 satisfies the relationship: 2.5 mm < d < 12 mm.

[0044] To facilitate the connection and fixation of the liquid receiver 30, in this embodiment of the invention, a connecting bracket is provided on the outer side wall of the compressor housing 10, and the liquid receiver 30 is mounted on the connecting bracket. Furthermore, to facilitate the installation of a horizontal compressor that can be top-mounted or wall-mounted, this embodiment of the invention uses two mounting brackets 11, which are spaced apart along the axial direction of the compressor housing 10 on the outer bottom of the compressor housing 10.

[0045] like Figures 6 to 8As shown, when the horizontal compressor of this embodiment, which can be mounted on the top or wall, is rotated 90° clockwise from the hypothetical frontal view, the original hypothetical vertical plane becomes a wall-mounted horizontal plane due to the 90° clockwise rotation, and the original hypothetical bottom plane becomes a wall-mounted vertical plane due to the 90° clockwise rotation. The range of the angle α formed by the hypothetical extension line of the slider groove 21 along its length direction and the wall-mounted vertical plane satisfies the relationship: 40° < α < 65°; the range of the angle δ formed by the hypothetical extension line of the pump oil pipe 22 along the radial direction of the pump body structure 20 and the wall-mounted vertical plane satisfies the relationship: 25° < δ < 80°; the axis of the section of the suction pipe 31 connected to the pump body structure 20 is perpendicular to the wall-mounted vertical plane. The range of the included angle β satisfies the relationship: 55° < β < 72°; the range of the included angle γ formed by the axis of the section connecting the exhaust pipe 40 to the compressor housing 10 and the vertical plane of the wall-mounted structure satisfies the relationship: 40° < γ < 65°; thus, even if the horizontal compressor of the embodiment of the present invention is rotated 90°, the port of the oil pump pipe 22 can still be located within the immersion range of the internal oil surface of the compressor housing 10 after being rotated 90°, so that the horizontal compressor of the embodiment of the present invention can still operate normally; thus, the horizontal compressor of the embodiment of the present invention can be used for both top-mounted and wall-mounted installation methods.

[0046] Therefore, the horizontal compressor that can be mounted on the roof or wall, provided by the embodiments of the present invention, improves the pump body structure 20 and the compressor housing 10 so that it can be applied to air conditioners with both roof-mounted and wall-mounted structures. For example, when applied to a roof-mounted air conditioner, the mounting bracket 11 at the bottom of the compressor housing 10 can be horizontally assembled. Since the slider groove 21 and the oil pump pipe 22 are located in the lower right region of the compressor housing 10, and the vent 24 and exhaust pipe 40 are located in the upper left region of the compressor housing 10, the refrigerant enters the pump body structure 20 from the liquid receiver 30 and drives the pump body structure 20 to operate. The high-pressure refrigerant gas discharged from the pump body structure 20 circulates inside the compressor housing 10, passes through the vent 24 in the upper left region, and is discharged from the exhaust pipe 40 in the upper left region. This creates a high pressure difference between the cavities on both sides of the pump body structure 20, allowing the oil pump pipe 22 to perform normal oil pumping operations and achieve lubrication of the internal structure. When the horizontal compressor of this embodiment is applied to a wall-mounted air conditioner, rotating it 90° clockwise from a hypothetical frontal view allows the mounting surface of the mounting bracket 11 away from the compressor housing 10 to be parallel to the vertical plane, facilitating vertical assembly of the mounting bracket 11. At this time, the slider groove 21 and the oil pump pipe 22 are located in the lower left area of ​​the compressor housing 10, while the vent 24 and exhaust pipe 40 are located in the upper right area of ​​the compressor housing 10. The oil level inside the compressor housing 10 can still submerge the oil pump pipe 22, allowing the oil pump pipe 22 to still perform normal oil pumping operations. In other words, by improving the design of the slider groove 21, vent 24, and oil pump pipe 22 of the oil pump structure, as well as the design of the exhaust pipe 40 and liquid receiver 30, the horizontal compressor of the present invention, which can be mounted on the roof or wall, can be used in air conditioners with both roof-mounted and wall-mounted installation methods. In this way, manufacturers do not need to design two different compressors for air conditioners with two different installation methods, which can effectively reduce design costs, material management costs, and other expenses, and effectively improve the applicability of the horizontal compressor of the present invention.

[0047] In addition, this embodiment of the invention also provides an air conditioner, which includes a horizontal compressor that can be mounted on the ceiling or wall-mounted as described in any of the above embodiments. By improving the design of the slider groove 21, vent 24, and oil pump pipe 22 of the oil pump structure, as well as the design of the exhaust pipe 40 and liquid receiver 30, this embodiment of the invention enables the air conditioner to be suitable for both ceiling-mounted and wall-mounted installation methods, thereby effectively improving the applicability of the air conditioner.

[0048] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention's horizontal compressor and air conditioner that can be mounted on the ceiling or wall. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
