[0001] The present invention relates to the technical field of air conditioners, and in particular to a compressor and an air conditioner having the same. Background Art

[0002] Car air conditioners generally use horizontal compressors, which are not only simple in structure and low in cost, but also take up little space in the height direction, which can greatly reduce the overall height of the unit and have more advantages in application space. At the same time, the compressor is installed horizontally, with a low center of gravity, small vibration amplitude, reduced risk of vibration cracking of the unit piping, low noise of the whole machine, high reliability, and good experience effect.

The relative position of the cylinder body and the flanges at both ends will change, causing the compressor's performance to deteriorate or even cause the cylinder to get stuck. Summary of the invention

DETAILED DESCRIPTION

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] Embodiment 1

[0027] Combined with Figure 1 and 2 As shown, this embodiment provides a compressor, including a housing 100, a pump body 200 and a motor installed in the housing 100; taking a roller compressor as an example, the pump body 200 of this embodiment generally includes a first flange 210, a first cylinder 220, a second cylinder 230, a second flange 240, a crankshaft 250, a first roller 260 and a second roller 270. The first cylinder 220, the second cylinder 230 and the second flange 240 of this embodiment are sequentially arranged along the axial direction of the pump body 200, one end of the crankshaft 250 is connected to the motor, and the other end passes through the first flange 210, the first cylinder 220, the second cylinder 230 and the second flange 240 respectively; the first roller 260 is located in the first cylinder 220, and the second roller 270 is located in the second cylinder 230. The other components and specific working principles of the roller compressor are common knowledge to those skilled in the art, so this embodiment will not be repeated.

[0028] When the compressor of this embodiment is a horizontal structure and is used in a car air conditioner, the inventor found that since the existing cylinder body and flange generally achieve the locking of the first cylinder body and the second cylinder body by a screw or bolt, the outer diameter of the compressor roller and the inner diameter of the cylinder are high-precision clearance assembly, and the minimum clearance design d is 0.01~0.05mm; and the minimum clearance between the screw diameter (about 6mm) and the screw hole diameter (about 7mm) is above 0.5mm. It can be seen that the clearance between the screw hole and the screw is much larger than the clearance between the roller and the cylinder of 0.01~0.05mm. Therefore, using threaded locking of the first cylinder body 220 or the second cylinder body 230 can only ensure that the longitudinal displacement of the cylinder body is not greater than 0.5mm when the vehicle body is driving, but the cylinder body will still longitudinally move within the displacement range of 0.01~0.05mm, but cylinder jamming may also occur within this range, reducing the reliability of the compressor.

[0029] Therefore, adopting a single screw connection structure can only ensure the integrity of the pump body 200, but cannot ensure the relative fixation of the cylinder body and the flange. Therefore, during the driving of the car, due to inertia, the relative position of the cylinder of the compressor pump body 200 assembly and the flanges at both ends will change, resulting in poor performance of the compressor or even cylinder jamming.

[0030] With regard to the above-mentioned problem, the improvement of the compressor of the present embodiment lies in that, in addition to the basic locking assembly locking the first cylinder body 220 and the second cylinder body 230, and the first flange 210 fixing the cylinder bodies to realize the fixed connection between the pump body 200 and the shell 100, the present embodiment also fixes at least one of the locked components to the shell 100, that is, the first cylinder body 220 and / or the second cylinder body 230 are fixedly connected to the shell, and in the present embodiment, the second cylinder body 230 is fixedly connected to the shell 100; in this way, after the locking assembly combines the first flange 210, the first cylinder body 220, the second cylinder body 230 and the second flange 240 into a whole, it can ensure that at least one of the locked components remains in a fixed state, thereby ensuring that the first cylinder body 220 and the second cylinder body 230 are in a relatively fixed state, preventing the cylinder bodies from moving, and improving the stability of the compressor operation.

[0031] The locking assembly of this embodiment is used to lock the first cylinder body and the second cylinder body. The first flange and the second flange are fixed at both ends of the locking assembly, that is, the locking assembly connects the first flange 210, the first cylinder body 220, the second cylinder body 230, and the second flange 240 into a whole in the horizontal direction to prevent the flanges and components from moving in the horizontal direction.

[0032] The locking assembly of this embodiment includes a first locking member 300 and a second locking member 400; wherein, one end of the first locking member 300 is connected to the first flange 210; the other end of the first locking member 300 passes through the first flange 210 and is connected to the first cylinder body 220; one end of the second locking member 400 is connected to the second flange 240; the other end of the second locking member 400 passes through the second flange 240 and the second cylinder body 230, and is connected to the first cylinder body 220; and the second cylinder body 230 is fixedly connected to the housing 100.

[0033] Specifically, the first locking member 300 and the second locking member 400 of the present embodiment are two screws of different lengths. Only the portion of the first locking member 300 connected to the first cylinder body 220 is provided with threads, and the remaining portion is a smooth rod body, and the first cylinder body 220 and the first flange 210 are connected to an integral structure through the threads and its own nut; and the second locking member 400 is also only the portion connected to the first cylinder body 220 is provided with threads, and the remaining portion is also a smooth rod body, and the second flange 240, the second cylinder body 230 and the above-mentioned integral structure are connected through its own nut and threads.

[0034] In order to improve the connection stability between the first locking member 300 and the first cylinder body 220, and between the second locking member 400 and the first cylinder body 220, the present embodiment firstly makes the length direction of the first locking member 300 and the second locking member 400 consistent with the axial direction of the pump body 200; and makes the projections of the first locking member 300 and the second locking member 400 on a plane parallel to the axial direction of the pump body 200 have overlapping parts, and the overlapping parts are located in the first cylinder body 220, that is, the length of the first locking member 300 extending into the first cylinder body 220 is h1, and the length of the second locking member 400 extending into the second cylinder body 230 is h2; the length of the first cylinder body 220 along the axial direction of the pump body 200 is H1; wherein, h1+h2>H1.

[0035] Based on the above structure, the inventor found that although the above structure can ensure the relative stability of the position of the second cylinder body 230, since there is no direct stable connection between the second cylinder body 230 and the second flange 240, the inventor made further improvements to the locking assembly and designed the locking assembly to also include a third locking member 500 and a fourth locking member 600; wherein, one end of the third locking member 500 is connected to the second flange 240, and the other end passes through the second flange 240 and is connected to the second cylinder body 230; one end of the fourth locking member 600 is connected to the first flange 210, and the other end passes through the first flange 210 and the first cylinder body 220 and is connected to the second cylinder body 230.

[0036] Similarly, the third locking member 500 and the fourth locking member 600 are also two screws of different lengths. The third locking member 500 has only a threaded portion connected to the second cylinder body 230, and the rest is a smooth rod body. The second cylinder body 230 and the second flange 240 are connected to form an integral structure through the thread and its own nut; and the fourth locking member 600 also has only a threaded portion connected to the second cylinder body 230, and the rest is also a smooth rod body. This structure not only strengthens the connection stability between the second cylinder body 230 and the second flange 240, but also further enhances the lateral connection stability of the various components of the pump body 200.

[0037] In order to further enhance the connection stability between the third locking member 500 and the second cylinder body 230, and between the fourth locking member 600 and the second cylinder body 230, the length direction of the third locking member 500 and the fourth locking member 600 of the present embodiment is consistent with the axial direction of the pump body 200; and the projections of the third locking member 500 and the fourth locking member 600 on a plane parallel to the axial direction of the pump body 200 have overlapping parts, and the overlapping parts are located in the second cylinder body 230, that is, the length of the third locking member 500 extending into the second cylinder body 230 is h3, and the length of the fourth locking member 600 extending into the second cylinder body 230 is h4; the length of the first cylinder body 220 along the axial direction of the pump body 200 is H2; wherein, h3+h4>H2.

[0038] In addition, the inventors have discovered that in order to improve the vibration resistance of the pump body 200, which in turn affects the performance of the compressor, the inventors have also made improvements to the connection method between the pump body 200 and the housing 100. That is, in addition to the second cylinder body 230 being fixedly connected to the housing 100, this embodiment also fixes other components of the pump body 200 to the housing 100, such as fixing the first cylinder body 220 and the second flange 240 to the housing 100. This structure can not only ensure the connection stability between the housing 100 and the pump body 200, but also improve the vibration resistance of the pump body 200.

[0039] Each component of the pump body 200 of this embodiment has at least one set of welding points with the housing 100, and each set of welding points includes at least two welding points. Moreover, preferably, the welding points of the same set of welding points are all located on the same component of the pump body 200 (for example, all located on the same flange or the same cylinder body), and more preferably, the welding points of the same set of welding points are all located on the same plane perpendicular to the axial direction of the pump body 200.

[0040] Specifically, there are many ways to connect the pump body 200 and the housing 100, for example Figure 1 As shown, the first flange 210 and the second cylinder body 230 are both welded to the housing 100 .

[0041] In addition to the above compressor structure, the compressor of the present invention can also be as follows Figure 3As shown, it includes a third cylinder body 280 in addition to the first cylinder body 220 and the second cylinder body 230, and the third cylinder body 280 is located between the first flange 210 and the first cylinder body 220; the first locking member 300 passes through the first flange 210 and the third cylinder body 280, and is connected to the first cylinder body 220. Since the first flange 210, the second flange 240, the first cylinder body 220 and the second cylinder body 230 have high stability through the above-mentioned welding and locking assembly connection, the third cylinder body 280 between the first flange 210 and the first cylinder body 220 also has good stability and will not produce relative displacement with the first flange 210, but those skilled in the art can add a locking assembly or a welding point to connect the third cylinder body 280 and the first flange 210 to improve its position stability.

[0042] and Figure 3 The welding position of the compressor in Figure 1 Similarly, welding points are also provided on the first flange 210 and the second cylinder body 230, and of course welding points can also be provided on the third cylinder body 280; or for example Figure 4 As shown, welding points are provided on the first flange 210 , the second cylinder body 230 and the first cylinder body 220 .

[0043] It should be noted that the compressor described in this embodiment can be used not only on vehicle-mounted horizontal compressors, but also on other compressors that have the same or similar technical problems as the vehicle-mounted horizontal compressors.
