Embodiment
Describe the preferred embodiments of the present invention in detail with reference to accompanying drawing.
With reference to Fig. 1, general structure according to compressor of the present invention is shown in the mode of sectional view.
As shown in fig. 1, hermetic compressor of the present invention comprises: be used for the compression unit 20 of compressed refrigerant, it is installed in the enclosing housing 10 that defines a closed interior space; And the driver element 30 that is used for drive compression unit 20.
Compression unit 20 comprises: cylinder body 21, and portion defines pressing chamber 21a within it; And piston 22, it carries out straight reciprocating motion in pressing chamber 21a, with compressed refrigerant.Side at cylinder body 21 is connected with cylinder cap 23, the suction chamber 23a that this cylinder cap 23 defines drain chamber 23b and communicates with the external world.Between cylinder body 21 and cylinder cap 23, be provided with control valve unit 24, be used to control the discrepancy of refrigeration agent.
Driver element 30 is used to make piston 22 straight reciprocating motions, in compression unit 20 refrigeration agent is compressed.Driver element 30 comprises: the stator 31 that is used to produce magnetic field; Be installed in stator 31 inside versatilely to carry out the rotor 40 of electrical interaction with it; Motor, it has the center that presses fit in described rotor 40 running shaft 32 together to rotate with rotor 40; And connecting rod 33, it is connected to running shaft 32 and is converted to straight line motion rotatablely moving, thereby makes piston 22 straight reciprocating motions.
Now will illustrate in greater detail in conjunction with the accompanying drawings according to rotor 40 of the present invention.
With reference to figure 2 and 3, rotor 40 of the present invention comprises the duplexer of being made up of the electrical sheet 41 of a plurality of stacked vertical 42; And be entrenched in a plurality of magnet among a plurality of groove 42a that limit on the outer circumferential face of duplexer 42.At this, a plurality of groove 42a separate in a circumferential direction each other equably.Be entrenched in a plurality of magnet 43 among the groove 42a with the mode setting of alternating polarity.
At upper support sheet 44 and lower support sheet 45 that the top and the bottom of duplexer 42 provide ring-type, it is used for axially support duplexer 42 and magnet 43.At this, a plurality of electrical sheets 41 and support plate 44 and 45 fixed relative to one another by a plurality of rivets that penetrate them.
Upper support sheet 44 is formed with a plurality of fixedly protuberance 44a that go up, and its upper surface towards magnet 43 protrudes downwards, radially breaks away to prevent magnet 43.Corresponding to fixing protuberance 44a on these, the upper surface of magnet 43 be formed with respectively a plurality of on attachment recess 43a, be used for inserting and go up fixedly protuberance 44a.Similarly, lower support sheet 45 is formed with a plurality of following fixedly protuberance 45a, and its lower surface towards magnet 43 is protruding upward, and is formed with a plurality of attachment recess 43b down respectively at the lower surface of magnet, is used for inserting down fixedly protuberance 45a.
Alternatively, as shown in Figures 4 and 5, can provide a plurality of fixedly protuberance 44a ' and following fixedly protuberance 45a ' of going up, it is set to support the outer circumferential face of each magnet 43 '.At this, in order to prevent fixing protuberance 44a ' and the fixing outwards outstanding outer circumferential face that surpasses magnet 43 ' of protuberance 45a ' down, on fixedly protuberance 44a ' and fixedly protuberance 45a ' inclination at a predetermined angle on the outward direction of magnet 43 ' down.In the present embodiment, by the upper surface of each magnet and the part of the seamed edge between the outer circumferential face are cut sth. askew, form a plurality of attachment recess 43a ' of going up, and, form a plurality of attachment recess 43b ' down by the lower surface of each magnet and the part of the seamed edge between the outer circumferential face are cut sth. askew.
Assembly process and the effect to the rotor 40 in the hermetic compressor according to the present invention now describes.
At first, sequentially with a plurality of electrical sheets 41 through on the rivet 46, thereby vertically stacked to form duplexer 42.Next, upper support sheet 44 is contained in the upper end of rivet 46, and lower support sheet 45 is contained in the lower end of rivet 46.Simultaneously, magnet 43 is fitted among a plurality of groove 42a that limit on the outer circumferential face of duplexer 42, and among the attachment recess 43a and 43b on fixedly protuberance 44a on support plate 44 and 45 and the 45a insertion magnet.In this way, with support plate 44 and 45 and duplexer 42 and magnet 43 link together.
After this, utilize independent anchor clamps that rivet 46 is riveted, thereby magnet 43 is fixed firmly on the duplexer 42 by support plate 44 and 45.
In this way, in the rotor 40 in hermetic compressor of the present invention, owing to can magnet 43 enough be firmly fixed by support plate 44 and 45, therefore no longer need independent cylinder part, and in traditional hermetic compressor, around the periphery of a plurality of magnet, need independent cylinder part for regularly.
Therefore, can be the spacing of cut between the electrical sheet of stator 31 that produces magnetic flux and rotor 40 to minimum, thus improve the delivery efficiency of motor.
By above explanation as seen, according to hermetic compressor of the present invention, the electrical sheet of magnet and formation rotor is interfixed securely.
Therefore, the present invention no longer need be around the independent fixed component of magnet, thereby can be the spacing of cut between the electrical sheet of stator that produces magnetic flux and rotor to minimum, and the result improves the delivery efficiency of motor and the driving efficient of compressor.
In addition, according to the present invention, be fixed together by the electrical sheet of support plate with magnet and rotor, the result has simplified overall operation, and has reduced cost of production.
Though for purposes of illustration the preferred embodiments of the present invention are disclosed, but those skilled in the art should be understood that, under the prerequisite of the scope of the invention that does not depart from claims and limited and spirit, can carry out various modifications, increase and replace.
