Speech is "inner" by the space of the claddings such as the main casing, tube wall and side wall, and the other side is "outside".
As shown in fig. 1, according to a kind of compressor of preferred embodiment of the present invention, including main casing 1 and liquid storage device 2,
Wherein, compression unit 3, and the piston that compression unit preferably includes cylinder and is installed in cylinder are installed in main casing 1,
Motor driving compression unit 3 in main casing 1 acts, and completes the compression of the refrigerant sucked from liquid storage device 2.
It is stored with refrigerant to be compressed in liquid storage device 2, passes through suction between the suction hole 30 on compression unit 3 and liquid storage device 2
The sealing connection of tracheae group 4, so that the gaseous coolant in liquid storage device 2 can be entered by suction hole 30 in main casing 1.Air intake duct
Group 4 includes conduit 40, connecting tube 41, air intake duct 42 and instlated tubular 43, wherein：
Conduit 40 is set on the periphery wall of main casing 1 and extends towards the direction of liquid storage device 2, is shown in Fig. 2 and Fig. 3
The molding mode of two kinds of conduits 40, wherein：Conduit 40 is integrally formed at by flanging process on main casing 1 in Fig. 2；It is led in Fig. 3
Pipe 40 is processed independently of main casing 1, and is fixed to each other with main casing 1 by fixed forms such as welding.
One end of connecting tube 41 is sealingly connected on the suction hole 30 of compression unit 3, the other end is pierced by simultaneously from conduit 40
Extend towards the direction of liquid storage device 2, the end of stretching conduit 40, which radially extends out, in connecting tube 41 is formed with the first flange 410.
One end of air intake duct 42 is sealingly connected to inside liquid storage device 2, the other end forms or be connected with second radially extended out
Flange 420.
The both ends of instlated tubular 43 are inserted into respectively in air intake duct 42 and connecting tube 41, and instlated tubular 43 uses the macromolecule of low melting point
Material is made, and to reduce refrigerant flow and the external heat transfer inside even isolation air intake duct group 4, compressor is avoided to inhale
Gas superheating phenomenon.
First flange 410 and the second flange 420 are welded to each other fixation, so that air intake duct 42 and connecting tube 41 are tightly connected.
Since the first flange 410 and the second flange 420 are that radial direction extends out structure, in the first flange 410 and second
The weld seam formed between flange 420 is radially away from the instlated tubular 43 in air intake duct group 4, even if the first flange 410 and second convex
Using higher welding forms of energy inputs such as gas shielded arc weldings between edge 420, the heat damage of instlated tubular 43 will not be caused.
Therefore, air intake duct group 4 with the above structure, can the seam crossing of the first flange 410 and the second flange 420 fill weld
Silk, and make welding wire melt to form weld seam by forms such as gas shielded arc weldings, in turn, using the air intake duct group 4 of this welding form
There is preferable fault-tolerant ability for fit-up gap and assembly precision, facilitates the mass production of the compressor using this air intake duct group 4.
It is the first preferred embodiment of air intake duct group 4 shown in Fig. 2.Wherein, the second flange 420 is located at air intake duct 42
1 side of close main casing free end, in this preferred implementation structure, molding of second flange 420 on air intake duct 42
It can also be to lead to welding etc. before being inserted into instlated tubular 43 by the technological forming that turns up that mode, which can be in the free end of air intake duct 42,
Form is formed.
In order to be further reduced the refrigerant flow that outside heat enters in instlated tubular 43, close to main casing 1 on air intake duct 42
One end be formed with flared section 421, and the second flange 420 is preferably disposed in the flared section 421, the flared section 421 so that every
Between the outer tube wall and the inner tubal wall of air intake duct 42 of heat pipe 43 heat-insulated gap is formed at 421 setting of flared section.Heat-insulated gap
The improvement that formation not only contributes to compressor air suction superheating phenomenon may be used also when the second flange 420 is set to the flared section 421
The radial spacing between weld seam and instlated tubular 43 to further increase 410 junction of the second flange 420 and the first flange is reduced
Influence of the energy input for instlated tubular 43 when welding.It is also preferred that extending out setting on the pipeline section of conduit 40 in connecting tube 41
(as shown in Figure 2), in this way, in the adjacent sidewalls of main casing 1, between 43 outer tube wall of instlated tubular and the inner tubal wall of connecting tube 41
Gap is formed, the suction superheat phenomenon of compressor can further be improved.
Further, as shown in the 5th kind of preferred embodiment of the air intake duct group 4 in Fig. 6, air intake duct 42 has limit
Protrusion 422, the end for stretching into air intake duct 42 of instlated tubular 43 is against the limit protrusion 422, so that instlated tubular 43 and air intake duct 42
Axially position can be realized by the limit protrusion 422.When installation, instlated tubular 43 can be firstly inserted into air intake duct 42, until every
After the end of heat pipe 43 contradicts the limit protrusion 422, then instlated tubular 43 is inserted into connecting tube 41, until the first flange 410 with
Second flange 420 abuts that the end of instlated tubular 43 is preferably extended over to suction hole 30 at this time.The formation of limit protrusion 422
Mode can with but be not limited to slot rolling processing, setting purpose is that the structure of indent is formed in the air intake duct 42, limits instlated tubular
43 axial position.
Further, end face and the conduit 40 backwards to the second flange 420 of the first flange 410 towards liquid storage device 2 from
It is tightly connected by end.Extend out setting since the first flange 410 is radial, what the internal diameter of conduit 40 can be done larger leads without consideration
The ferrule problem of pipe 40 can pass through in this way, even if cylinder 3 deposits installation site in the vertical direction there are when error
Increase conduit 40 internal diameter form allow the installation site error presence, avoid air intake duct group 4 because installation error and
It occurs bending and deformation when across conduit 40, and passes through the nozzle of 410 sealing duct 40 of the first flange radially extended out.
It is second of preferred embodiment of air intake duct group 4 shown in Fig. 3.The knot of itself and air intake duct group 4 shown in Fig. 2
Structure difference lies in：Further include flange 44 in air intake duct group 4, which, which has, is arranged on the outer tube wall for being fixed to air intake duct 42
Linkage section 440, the second flange 420 are formed on the linkage section 440.The pipe end in Fig. 2 in air intake duct 42 is different from directly to be formed
The form of second flange 420, in embodiment shown in Fig. 3, by air intake duct 42 fixing sleeve try orchid 44, to make suction
There is the second flange 420 on tracheae 42.Flange 44 can be welded and fixed to by flange 44 in advance in the manufacturing process of liquid storage device 2
On air intake duct 42.
The linkage section 440 of flange 44 shown in Fig. 3 is directly protruding into connecting tube 41, not with the outer tube wall of instlated tubular 43
Between the inner tubal wall of connecting tube 41.Differently therefrom, in the shown in fig. 7 6th in preferred embodiment, linkage section 440 is not
It stretches between instlated tubular 43 and connecting tube 41, and is directly fixed on the outer tube wall of air intake duct 42.
In the third preferred embodiment of air intake duct group 4 shown in Fig. 4, the area with embodiment shown in Fig. 3
Do not essentially consist in the generation type of conduit 40, the conduit 40 of air intake duct group 4 shown in Fig. 3 is molded independently of main casing 1, Fig. 4
In conduit 40 be then integrally formed on main casing 1.
In the 4th shown in Fig. 5 in preferred embodiment, the difference with embodiment shown in Fig. 4 essentially consists in：
It is arranged on air intake duct 42 in the flared section 421 being fixed on air intake duct 42.
