Embodiment
Below, be described with reference to the accompanying drawings embodiments of the invention.But content of the present invention is not limited to embodiment's content, and technician of the same trade can propose other embodiment on basis of the present invention, but these embodiments belong within the scope of the present invention.
Fig. 2 is the sectional view of Linearkompressor of the present invention.
Linearkompressor provided by the invention comprises as shown in Figure 2: housing 100; The main body frame 110 of nonmagnetic substance; Cylinder 120; Piston 130; Output covers 140.
Housing 100 has constituted the outward appearance of Linearkompressor, and has formed containing space in inside.And the one side is provided with the outflow opening 100b that makes outside refrigerant can flow into inner inflow entrance 100a and export the refrigerant after compressing.And housing 100 is to be made of upper body 101 and lower case 102.Here, two inflow entrance 100a are separately positioned on upper body 101 or the lower case 102.Oil has been loaded in bottom in lower case 102, and is provided with elastic member 100c and is flexibly supporting main body frame 110.
Chocking construction 200 should be formed on the upper body 101 at least, and in the present embodiment, a corner of upper body 101 has formed the recessed structure of inside survey, thereby has constituted chocking construction 200.Chocking construction 200 can form by the manufacture of punching press, forging or casting.Detailed description for chocking construction 200 will be carried out below.
Main body frame 110 is by the elastic member 100c elastic support that is arranged on the housing 100.This is the vibrations that produce for the straight reciprocating motion that absorbs piston 130, suppresses the generation of noise and vibrations thus.Main body frame 110 rocks in the inside of housing 100 when linear compressor operation thus.Because various parts will be set on main body frame 110, thereby the structure more complicated of main body frame 110.Wherein, the position of the main body frame 110 that contacts with chocking construction 200 is to be positioned at the main body frame 110 that 140 sides are covered in output in the present invention, is and upper body 101 immediate positions.Be called contacting part 300 in the present embodiment.
Cylinder 120 has adopted the material of wear resistance, is fixed on the side of main body frame 110.And, the space of the refrigerant after being formed with the output compression on the one end, and be provided with the output lid 140 that is connected with outflow opening 100b.Output cover the iron that 140 general employings have magnetic (S45C, S20C).
One side of piston 130 is by elastic member 110a, and the 110b elastic support is carried out straight reciprocating motion thus in the inboard, and the opposite side of piston 130 is connected on the linear electric machine 150 that possesses external stator 152 and inner stator 151.The part that is connected with linear electric machine 150 is made of permanent magnet 153.The enlarged portion 131 that is used for mounting permanent magnet 153 is arranged on the opposite side of piston 130.A side of doing straight reciprocating motion in cylinder 120 of piston 130 is provided with the inlet hole 130h that the refrigerant that will flow into by intake channel 100a is sucked into the compression volume P that is formed by cylinder 120 and piston 130, is provided with the inhaling valve 132 with valve effect in the outside of the side that is formed with inlet hole 130h.
The outside of the cylinder 120 that 140 refrigerants by piston 130 compression that are arranged on compression volume P export cover in output.Cover 140 inside in output and be provided with output valve assembly 141a, 141b can export the refrigerant that is compressed by piston 130 of compression volume P inside thus.And output is covered a side of 140 and is connected on the outflow opening 100b.
In order to make chocking construction 200 can avoid exporting to cover 140 inboards that are subjected to pasting behind the magnetic force lower case 102, chocking construction 200 should make in main body frame 110, be provided with contacting part 300 that output cover 140 1 sides to the distance of upper body 101 less than covering 140 to the distance the lower case 102 from exporting.Therefore, for make between chocking construction 200 and the contacting part 300 distance less than output cover 140 with the distance of lower case 102, should make the corner portion of this position of upper body 101 recessed to the inside, its method that is recessed into has casting, forging and moulding etc.
According to aforesaid structure, cover 140 with before lower case 102 contacts in output, the chocking construction 200 that is arranged on the upper body 101 contacts with the contacting part 300 of an end of the main body frame 110 that is made of nonmagnetic substance, has suppressed the mistake running and the vibrations/generating noise of Linearkompressor thus.
