Detailed description of the invention
Below, the embodiment of the accumulator involved by the utility model is described.
Fig. 1 is the longitudinal section of the brief configuration of the accumulator illustrated involved by embodiment of the present utility model, and Fig. 2 is the top view of the filter shown in Fig. 1, and Fig. 3 is the upward view of the filter shown in Fig. 1.
As shown in Figure 1, the accumulator involved by present embodiment possesses: the container body 1 of hermetic type; Inlet tube 5, the top of the through container body 1 of this inlet tube 5 is arranged, and makes the cold-producing medium of refrigerant loop flow in container body 1; Outlet 6, the bottom of the through container body 1 of this outlet 6 is arranged, and the cold-producing medium in container body 1 is flowed out to refrigerant loop; Filter 7, this filter 7 the upper and lower separated mode of container body 1 inside to be arranged, and makes the cold-producing medium from inlet tube 5 pass through; And be arranged at multiple permanent magnet 9a, 9b of filter 7.
Container body 1 such as by the main part 2 of drum, to carry out airtight upper end plate 3 to the upper opening of main part 2 and carry out airtight lower end plate 4 to the lower openings of main part 2 forming.Inlet tube 5 is such as connected with the cross valve on refrigerant loop via refrigerant piping, and outlet 6 is connected via the suction inlet of refrigerant piping with the compressor on refrigerant loop.This outlet 6 is provided with spill port 6a, and this spill port 6a returns compressor for making the oil of the lower end plate 4 lodging in container body 1.
Filter 7 is made up of metal, and is formed as circular as shown in FIG. 2 and 3.This filter 7 is made up of the 1st filter part 7a and the 2nd filter part 7b, 1st filter part 7a is formed as the unlimited spill in top and the central portion of this depression is opposed with inlet tube 5, and the 2nd filter part 7b is from the upper end flatly bending laterally of the 1st filter part 7a.The part except central portion of the 1st filter part 7a is formed as mesh-shape, catches the foreign matter being mixed into cold-producing medium.2nd filter part 7b is formed as the mesh mesh-shape thicker than the mesh of the 1st filter part 7a.Above-mentioned foreign matter is such as residuing in inner iron powder, the chip etc. of iron when manufacturing compressor.
At the central portion (part without mesh) by inlet tube 5 side of the 1st filter part 7a, be provided with the cold-producing medium diffusion part 8 that the cold-producing medium from inlet tube 5 is radially spread.Cold-producing medium diffusion part 8 is made up of metal, and is formed as conical.Cold-producing medium diffusion part 8 is such as fixed in the central portion of the 1st filter part 7a by welding.This cold-producing medium diffusion part 8 is utilized to make radially to spread along inclined plane 8a from the cold-producing medium of inlet tube 5.
Multiple permanent magnet 9a, 9b are configured at the face by outlet 6 side of the 1st filter part 7a, adsorb the foreign matter captured by the 1st filter part 7a.Above-mentioned permanent magnet 9a, 9b are such as installed by welding.Permanent magnet 9a is configured with multiple at the bottom lower surface of the spill of formation the 1st filter part 7a in the circumferential direction, and permanent magnet 9b is configured with the number identical with permanent magnet 9a at the outer surface in the sidewall portion of this spill.
That is, as shown in Figure 3, permanent magnet 9a, 9b radially configures centered by the axle center of filter 7.Permanent magnet 9a, 9b have the magnetic force that magnetic field is interfered mutually respectively.Thereby, it is possible to make foreign matter that is iron powder etc. be adsorbed on the 1st filter part 7a.In addition, though permanent magnet 9a, 9b are configured at respectively same in the heart, also can make permanent magnet 9a relative to permanent magnet 9b in the circumferential direction stagger.
The effect of Fig. 4 and Fig. 5 to the filter 7 in the accumulator formed in the above described manner is used to be described.
Fig. 4 is the longitudinal section of the accumulator of the flowing of cold-producing medium when the few foreign by the filters trap of Fig. 1 is shown, and Fig. 5 is the longitudinal section of the accumulator of the flowing of cold-producing medium when illustrating many by the foreign matter of the filters trap of Fig. 1.
When the initial driving by compressor, the cold-producing medium of refrigerant loop flows in container body 1 from inlet tube 5, this cold-producing medium arrow as shown in Figure 4 (dotted line) radially spreads by cold-producing medium diffusion part 8 like that, flow downwards along inclined plane 8a, by the bottom of the 1st filter part 7a and the fine mesh in sidewall portion, and flow down to the lower end plate 4 of container body 1.Now, the foreign matter being mixed into cold-producing medium is caught by the fine mesh of the 1st filter part 7a, and the foreign matter captured is adsorbed in multiple permanent magnet 9a, 9b.
When the fine mesh of the 1st filter part 7a along with the absorption because of foreign matter is blocked, cold-producing medium from inlet tube 5 lodges on the 1st filter part 7a, and when overflowing from the 1st filter part 7a, arrow (dotted line) is as shown in Figure 5 such, by the coarse mesh of the 2nd filter part 7b, and flow down to the lower end plate 4 of container body 1.
As above, according to embodiment, filter 7 is made up of the 1st filter part 7a and the 2nd filter part 7b, and the 1st filter part 7a is formed as the unlimited spill in top and the central portion of this depression is opposed with inlet tube 5, and the 2nd filter part 7b is from the upper end flatly bending laterally of the 1st filter part 7a.Therefore, the initial cold-producing medium flowed into from inlet tube 5 flows into the cancellous 1st filter part 7a that catches the foreign matter being mixed into cold-producing medium and passes through, and the foreign matter being therefore mixed into cold-producing medium is caught by the 1st filter part 7a and accumulates gradually.And when when the 1st filter part 7a is covered by foreign matter, cold-producing medium is difficult to flowing, this cold-producing medium is gradually to the 2nd filter part 7b flowing.Thus, do not exist and become at the cold-producing medium of refrigerant loop circulation the situation being difficult to flow in container body 1, foreign matter can be suppressed to flow in compressor, the raising of compressor reliability can be realized.
In addition, owing to being provided with conical cold-producing medium diffusion part 8 at the central portion of the 1st filter part 7a, therefore not existing and make to be caught by the 1st filter part 7a and permanent magnet 9a, 9b and the such situation of the scattering foreign matter adsorbed.Therefore, it is possible to suppress foreign matter to be mixed into the situation of the cold-producing medium flowed out from outlet 6 to refrigerant loop.
In addition, in embodiments, cold-producing medium diffusion part 8 is arranged on the central portion of the 1st filter part 7a, but also cold-producing medium diffusion part 8 can be taken off.In this case, the initial cold-producing medium flowed into from inlet tube 5 radially disperses together with foreign matter, but this foreign matter is caught by the sidewall portion of the 1st filter part 7a and adsorbs.And, when foreign matter cover the mesh of the 1st filter part 7a and cold-producing medium become be difficult to flowing time, this cold-producing medium flows to the 2nd filter part 7b and passes through gradually.In the case of such a construction, do not exist yet and become at the cold-producing medium of refrigerant loop circulation the situation being difficult to flow in container body 1, foreign matter can be suppressed to flow in compressor, the raising of compressor reliability can be realized.
In addition, in embodiments, the 2nd filter part 7b is formed as the mesh-shape that mesh is thicker than the mesh of the 1st filter part 7a, but, replace in this, also the 2nd filter part 7b can be formed as tabular, the i.e. porous plate with multiple hole.2nd filter part 7b is linked by the upper end of welding with the 1st filter part 7a.According to this structure, when foreign matter cover the mesh of the 1st filter part 7a and cold-producing medium become be difficult to flowing time, this cold-producing medium flows to the 2nd filter part 7b and passes through gradually, therefore do not exist and become at the cold-producing medium of refrigerant loop circulation the situation being difficult to flow in container body 1, foreign matter can be suppressed to flow in compressor, the raising of compressor reliability can be realized.
