Description
Technical field
The present invention relates to Linearkompressor, particularly relate to the vibration-proof structure of Linearkompressor.
Background technique
In general, compressor is after power generating apparatus such as motor or turbo machine receive power, air, refrigerant or other working gas are compressed and improve the mechanical device of its pressure, compressor is widely used in household appliances and whole industry fields such as refrigerator, air conditioner.
Compressor generally can be divided into: between piston and cylinder, form to inhale, the compression volume of discharging working gas, and the reciprocal compressor that when straight reciprocating motion is done in the inside of cylinder, refrigerant compressed of piston; Between roller that off-centre is being rotated and cylinder, form inhale, the compression volume of discharging working gas, rotate the rotary compressor that refrigerant is compressed by rolling the off-centre of ring in cylinder; Between movable orbiting scroll and static vortex disk, form to inhale, the compression volume of discharging working gas, rotate with respect to static vortex disk and scroll compressor that refrigerant is compressed by movable orbiting scroll.
In recent years, people are in to the reciprocal compressor research process, develop piston and directly be connected on the drive motor of doing linear reciprocating motion, avoided the mechanical loss due to the movement conversion, thereby can improve compression efficiency and Linearkompressor simple in structure.
Generally for Linearkompressor, in the enclosure interior of sealing, piston is done linear reciprocating motion in cylinder under the driving of linear electric machine, meanwhile suck refrigerant, compress and discharge.Be provided with permanent magnet between the internal stator of linear electric machine and outer stator, permanent magnet is done straight reciprocating motion under the effect of electromagnetic force.Piston links to each other with permanent magnet and along with the motion of permanent magnet does reciprocating linear motion in cylinder, thereby sucks refrigerant, compresses and discharge.

This body support frame 3 is arranged in the above-mentioned holding space and passes through elastic member 5 elastic support.This body support frame 3 is generally made in the mode of die casting.The component parts that will describe below this body support frame 3 is provided with.
Linear electric machine 10 inserts the front that is arranged on this body support frame 3, and linear electric machine 10 comprises internal stator 12 and outer stator 14.Internal stator 12 has a plurality of metallic laminations, these laminations be arranged on the cylinder circumferential surface around and along radial directed.Outer stator 14 comprises coil winding 14a.
Piston 4 inserts and is arranged on the inside of cylinder 2, and is formed with the friction part made from high-abrasive material on its outer circumferential face.In addition, extend to the circumferencial direction of piston 4 and to be provided with piston holder 24, piston holder 24 is provided with elastic member 24a, to provide elastic force to piston 4.In addition, the end between piston holder 24 and piston 4 is provided with magnet holder 6, and magnet holder 6 is provided with permanent magnet 16 and permanent magnet 16 between internal stator 12 and outer stator 14.The electromagnetic force that linear electric machine 10 is produced makes permanent magnet 16 do straight reciprocating motion, carries out straight reciprocating motion in cylinder 2, compresses the refrigerant that is inhaled into thereby drive piston 4.In order to obtain higher efficient, preferably the elasticity coefficient by the elastic member 24a that is connected in piston holder 24 is identical with the frequency of okperation of linear electric machine 10 with the determined frequency of refrigerant.
But there is following shortcoming in the as above vibration-proof structure of the Linearkompressor of structure:
Need middle damper 21 is inserted in the elastic member 5 in manufacture process, the comparison difficulty operates; Damper 21 broke away from elastic member 5 in the middle of the vibration that continues to take place also can make, and had influenced the quality of product; Need moulding respectively to make top damper 22 and left and right sides damper 23, reduced manufacturing efficiency.
Summary of the invention
Have problems in order to solve in the above-mentioned prior art, the present invention and purpose are damper is integrally formed on this body support frame, thereby under the vibration environment that continues, also can keep the function of damper, improve convenience and manufacturing efficiency that the durability of Linearkompressor and quality, raising are made thus.
In order to achieve the above object, the vibration-proof structure of Linearkompressor of the present invention comprises: the housing that is formed with inner holding space; This body support frame that is arranged in the inner holding space and supports by elastic member; Be arranged on the linear electric machine on this body support frame; Be fixedly installed on the electrical machinery cover on the linear electric machine; Protrusion is arranged on a side of electrical machinery cover, with the rear baffler in the refrigerant suction compressor that flow in the housing; Upper and lower end protrusion at this body support frame is formed with the upper and lower damper that the restriction Linearkompressor moves up and down; Left and right end protrusion at this body support frame is formed with the left and right damper that the restriction Linearkompressor rotatablely moves.
In addition, the vibration-proof structure of Linearkompressor of the present invention also comprises: be arranged on the corresponding housing of rear baffler on, the rear damper that moves downward of restriction rear baffler.
The present invention with said structure, the moulding by this body support frame provides damper, thereby has improved the convenience of operation, has improved manufacturing efficiency.In addition, in the present invention, damper is integrally formed on this body support frame, thereby under the vibration environment that continues, also can keeps the function of damper, can improve the durability of Linearkompressor thus.
