Description
Technical field
The present invention relates to a kind of Linearkompressor, more particularly, relate to a kind of noise that in the process of compressed fluid, produces and Linearkompressor that vibrates and can improve compression efficiency of reducing.
Background technique
Usually Linearkompressor is configured to the linear driving force from linear electric machine is passed to piston, makes piston make linear reciprocating motion in cylinder, thus inlet and compressed fluid.
Fig. 1 is the longitdinal cross-section diagram of conventional linear compressor.
As shown in Figure 1, traditional Linearkompressor comprises inner chamber 10, and inner chamber 10 is installed on the inside of hermetic seal housing 1.The cylinder body shape of inner chamber 10 for having specific length.Bonnet 20 is fixed in a side of inner chamber 10, and fluid inlet passage 18 is formed on the bonnet 20.The drive motor 30 that produces driving force is installed on the inside of inner chamber 10.
Piston 40 is connected with drive motor 30, and fluid passage 38 is formed in the piston 40.Being used for the inlet valve 50 of opening and closing fluid passage 38 is installed on the piston 40.Cylinder body 60 with cylinder 58 is fixed in the opposite side of inner chamber 10, and piston 40 is assemblied in the cylinder 58 movably, so that piston 40 can seesaw in cylinder 58.The outlet valve 70 of opening and closing cylinder body 58 is installed on the cylinder body 60.
Inlet connecting tube 2 is connected on the hermetic seal housing 1, makes inlet connecting tube 2 be arranged at the rear portion of the fluid inlet passage 18 of bonnet 20, is imported in the hermetic seal housing 1 by this inlet connecting tube from the fluid in the outside.
Drive motor 30 comprises: stator S, stator S comprise that the outer laminated core 31 of cylindrical shape, the interior laminated core 32 and of cylindrical shape are wrapped in the coil 33 on the outer laminated core 31, and wherein interior iron core 32 separates a specified gap with outer iron core 31; Magnet 34, this magnet 34 are configured to make it can front/rear motion between outer iron core 31 and interior iron core 32; With a magnet frame 36 that is connected on the piston 40, piston 40 front/rear motion with the front/rear motion of magnet 34.Magnet 34 is fixed on the magnet frame 36.
In inner chamber 10, outer iron core 31 is fixedly installed on the bonnet 20.Interior iron core 32 is fixedlyed connected with the cylindrical shape connected element 21 on being formed on bonnet 20.Magnet 34 is fixed on the outer periphery of magnet frame 36 and is arranged between outer iron core 31 and the interior iron core 32.
The first spring 37a that is arranged between magnet frame 36 and the cylinder body 60 flexibly supports magnet frame 36.Be arranged at the second spring 37b support piston 40 flexibly between piston 40 and the interior iron core 32.
Inlet valve 50 is plate valves, and a side of this plate valve is fixed on the piston 40, and it is flexibly crooked to be used for the plate valve part of fluid passage 38 of opening and closing piston 40.
Therefore, when piston 40 during backward towards bonnet 20 motion, the fluid in the fluid passage 38 makes that to be used for the part of inlet valve 50 of fluid passage 38 of opening and closing piston 40 crooked on the direction relative with bonnet 20, thereby opens fluid passage 38.On the other hand, when piston 40 during to previous dynasty outlet valve 70 motion, the fluid between inlet valve 50 and the outlet valve 70 and the elastic force of inlet valve self are used in the part of inlet valve 50 of the fluid passage 38 of opening and closing piston 40 and stretch on the direction relative with outlet valve 70, thereby close fluid passage 38.
Outlet valve 70 comprises: be installed on the cylinder body 60 and outlet cover 72 and valve body 76 that a side is connected with outer pipe, this valve body rests on the outlet valve 72 by spring 74, and valve body 76 is arranged to make its closely end of contact cylinder 58, with opening and closing cylinder 58.
In above-mentioned Linearkompressor, when inlet valve 50 opening and closing, inlet valve 50 collides to piston 40, thereby produces noise.In addition, when outlet valve 70 opening and closing, valve body 76 collides cylinder 58, thereby produces noise.The fluid through-hole of the fluid passage 38 of these noises by piston 40, interior iron core 32 and the fluid inlet passage 18 of bonnet 20 are delivered to the outside of hermetic seal housing 1, as shown in Figure 1.
Therefore, baffler is installed in addition in the noise transmission path, is arrived the outside of hermetic seal housing 1 to prevent noise transmission.
Baffler 80 is fixedly connected on the rear portion of piston 40 and separates with the fluid inlet passage 18 of bonnet 20.Baffler 80 has the fluid bore 82 that vertically runs through, and the fluid in the fluid inlet passage 18 of the bonnet 20 that entered the mouth flows in the fluid passage 38 of piston 40 by fluid bore 82.Baffler 80 is constructed such that the diameter of intermediate portion of fluid passage 82 is greater than the diameter of the front and rear part of fluid passage 82.
The operation that now description is had the conventional linear compressor of said structure.
When to coil 33 supplying electric currents, drive motor 30 runnings cause magnet 34 to make linear reciprocating motion.The to-and-fro motion of magnet 34 passes to piston 40 through magnet frame 36.As a result, piston 40 is made linear reciprocating motion in cylinder 58.
Along with piston 40 is made linear reciprocating motion in cylinder 41, outlet valve 70 and inlet valve 50 are unlocked and close.At this moment, the fluid passage 38 that imports fluid passage, baffler 80 and the piston 40 of fluid inlet passage 18 by bonnet 20 of gaseous fluid in the hermetic seal housing 1, interior iron core 32 flows in the cylinders 58.Gaseous fluid is compressed in cylinder 58, is exported then.The high temperature and high pressure gas of outlet is discharged to the outside of hermetic seal housing 1 by the outer pipe (not shown).
But in having the Linearkompressor of said structure, baffler 80 separates along with piston 40 to-and-fro motion and with the fluid inlet passage 18 of bonnet 20.Thereby the fluid that the fluid inlet passage 18 by bonnet 20 is imported into can not promptly flow in the fluid passage 38 of cylinders, shown in the solid line among Fig. 1 by baffler 80.Therefore, reduce the introducing efficient (introductionefficiency) of Linearkompressor, thereby reduced the performance of compressor.
