Detailed implementation manners

[0024] Refer to in combination Figures 1 to 7As shown, according to an embodiment of the present invention, a liquid distributor is provided, which includes a housing. The housing includes a first housing 11 and a second housing 12. The aforementioned first housing 11 can specifically be an upper housing, and the second housing 12 is the remaining part of the housing below the upper housing. An intake pipe 202 (also known as a compressor suction pipe) is welded to the top of the first housing 11. A filter assembly 204 is provided on the outflow path of the intake pipe 202. The filter assembly 204 can be connected to the inner wall of the first housing 11 through a corresponding bracket. The liquid distributor further includes a first support member 21. The first support member 21 includes an annular groove connector and a fixed connector 216. The annular groove connector has a first annular groove 212 facing the first housing 11 and a second annular groove 213 facing the second housing 12. The first end of the first housing 11 is detachably connected to the first annular groove 212, and the first end of the second housing 12 is detachably connected to the second annular groove 213. A first seal 214 is provided between the first end of the first housing 11 and the bottom wall of the first annular groove 212, and a second seal 215 is provided between the first end of the second housing 12 and the bottom wall of the second annular groove 213. The fixed connector 216 is used for fixedly connecting to the compressor housing 100. The aforementioned first seal 214 and second seal 215 can specifically be rubber sealing rings resistant to refrigerant corrosion, etc. In this technical solution, the axial, radial, and circumferential limiting and positioning connections of the first housing 11 and the second housing 12 are respectively achieved through the first annular groove 212 and the second annular groove 213, which can increase the modal frequencies of each order of the liquid distributor. Additionally, by providing the first seal 214 and the second seal 215 between the mating components, effective sealing between the two connected components can be achieved while reducing the vibration of the overall liquid distributor, and reducing the resonance problems caused by each order of the modal of the liquid distributor.

[0025] In a specific embodiment, refer to Figure 3 and Figure 4As shown, the first annular groove 212 is formed by a first inner annular wall 31 and a first outer annular wall 32 that are concentrically and spaced apart. There is a threaded connection between the first end of the first housing 11 and the first inner annular wall 31; and / or, the second annular groove 213 is formed by a second inner annular wall 41 and a second outer annular wall 42 that are concentrically and spaced apart. There is a threaded connection between the first end of the second housing 12 and the second inner annular wall 41. The threaded connection facilitates the connection of the first housing 11 and the second housing 12 to the first support member 21 respectively. In a preferred embodiment, a third seal 217 is clamped between the first outer annular wall 32 and the outer wall of the first housing 11 within the first annular groove 212; and / or, a fourth seal 218 is clamped between the second outer annular wall 42 and the outer wall of the second housing 12 within the second annular groove 213. The aforementioned third seal 217 and fourth seal 218 can reduce the vibration transmission between the two housings and the first outer annular wall 32 and the second outer annular wall 42 respectively while achieving the sealing of the annular groove, further reducing the vibration of the liquid distributor and the noise caused by the vibration.

[0026] In some embodiments, a support body 51 is provided at the central through-hole of the first support member 21. At least part of the outer peripheral edge of the support body 51 is connected to the inner side of the first inner annular wall 31 and / or the second inner annular wall 41. The support body 51 has a flow-through hole 52 and a pipe support hole 53. The outlet pipe 201 within the housing passes through the pipe support hole 53 and there is a vibration damping member 54 between the outlet pipe 201 and the pipe support hole 53. The vibration damping member 54 can specifically be a vibration damping ring gasket (such as a rubber ring), or can also be a structure with damping such as a spring. Through the vibration damping member 54, the rigid connection between the outlet pipe 201 and the wall of the pipe support hole 53 is effectively eliminated, realizing the support of the outlet pipe 201 by the support body 51, increasing the modal frequency of the outlet pipe 201, and reducing the vibration caused by the vibration transmission of the outlet pipe 201 to the housing. The aforementioned support body 51 can be a plate structure, as Figures 3 to 5 shown in, or can also be a cross rib structure, as Figure 6 shown.

[0027] As Figure 7 shown, in another embodiment, the first housing 11 is an upper cylinder, the second housing 12 includes a middle cylinder 121 and a lower cylinder 122, and further includes a second support member 61. The second support member 61 has the same structure as the first support member 21, and the second support member 61 is connected between the middle cylinder 121 and the lower cylinder 122 so as to effectively support the housing of the liquid distributor and the outlet pipe 201 therein from the upper and lower regions of the liquid distributor. One end of the suction elbow 203 is communicated with and welded to the outlet of the outlet pipe 201, and the other end of the suction elbow 203 is welded to the suction port of the pump body assembly of the compressor, and the outlet of the outlet pipe 201 is simultaneously welded to the lower cylinder 122 as a whole.

[0028] As a specific implementation of the aforementioned fixed connecting member 216, refer to Figure 5 and Figure 6 As shown, the fixed connecting member 216 has a mating connecting plate 2161 and connecting ribs 2162 located between the first outer ring wall 32 and / or the second outer ring wall 42 and the mating connecting plate 2161. The mating connecting plate 2161 has a curved surface (arc surface) that matches the outer curved surface of the compressor housing 100, so that a reliable connection can be formed between it and the compressor housing 100. Generally speaking, it is preferred to use welding to achieve the connection between the mating connecting plate 2161 and the compressor housing 100 to ensure a reliable connection and prevent vibration and detachment.

[0029] According to an embodiment of the present invention, there is also provided a compressor, including a liquid distributor 200, and the liquid distributor 200 is the aforementioned liquid distributor. Specifically, a motor assembly (not shown in the figure) and a pump body assembly (not shown in the figure) are assembled in the compressor housing 100 from top to bottom. The fixed connecting member 216 of the first support member 21 is connected to the compressor housing 100 corresponding to the upper region of the motor assembly. When the liquid distributor includes a second support member 61, the fixed connecting member 216 of the second support member 61 is connected to the compressor housing 100 corresponding to the region between the motor assembly and the pump body assembly. In this way, the first support member 21 and the second support member 61 can avoid the excitation of the motor assembly and the pump body assembly, and prevent the vibration of the motor assembly and the pump body assembly from being directly transmitted to the support members, resulting in an increase in the vibration of the liquid distributor.

[0030] According to an embodiment of the present invention, there is also provided an air conditioner, including the aforementioned compressor.
