Therefore can avoid the compressor vibration-proof structure on electric efficiency impact as far as possible, assume vibration damping simultaneously
The height dimension of element is constant, and the outer circumferential being arranged on stator core obviously can make vibration damping unit
The setting height(from bottom) of part, higher than the bottom surface of stator core, the most also can be effectively improved compressor vibration damping
The setting height(from bottom) that structure is overall.
Fig. 4 A, 4B, 5A, 5B show the modular construction of a kind of concrete vibration damping fixed structure
Form and mounting structure form.Wherein, vibration damping fixed structure is the sleeve 12 with shirt rim 12a,
This sleeve 12 is sheathed and is fixed on the outer circumferential profile of stator core 4a, and damping element
It is arranged on the 12a of shirt rim.The installation of damping element for convenience, preferably under the 12a of shirt rim
Edge arranges at least three protuberance 12b, and at least three damping element is separately mounted at least three
On individual described protuberance 12b, protuberance 12b can be equiangularly spaced along the circumference of shirt rim 12a
Arranging, its quantity may be selected to be 4 shown in Fig. 4 A, it is also possible to increases and decreases according to actual requirement
Its quantity.Protuberance 12b can be made up of the mode shearing punching press, adopts and the most such as welds
The mode connecing bulge-structure is equally possible.
Owing to sleeve 12 to have carried damping element and the connection of whole compressor movement, therefore
Need realization to be tightly fastened between sleeve 12 and the outer circumferential profile of stator core 4a to be connected.
Preferably employ interference fit, such as interference fit 0.02～0.05mm, in order to shrink-on
Join and ensure enclasping force.Other feasible being fastenedly connected also apply be applicable to this utility model.In peace
When dress and debugging, utilize instrument can also make the vibration damping fixed structure (sleeve in such as Fig. 5 B
12) axial location relative to described stator core 4a is adjustable, i.e. changes being inserted between the two
Depth H.
Vpg connection at shirt rim 12a, it is preferred to use circular, this shape is easy to add punching in man-hour
Molded, and in Fig. 4 A, the top side of the shirt rim 12a of sleeve 12 be provided with one first straight
Line limit 12c, this first straight line 12c then can realize other structures or pressure on compressor
Dodging of other structures outside contracting machine, can be processed by clicking technique.Such as shown in Fig. 3
The acoustic filter 7 of the cylinder head side being arranged on described frame 1, when frame 1 is arranged on stator
During the upper surface of iron core 4a, acoustic filter 7 is placed exactly in the side of stator core 4a, in order to keep away
Exempt from the interference that acoustic filter 7 is installed by sleeve 12, therefore can arrange first on the 12a of shirt rim straight
Line limit 12c.Certainly according to actual requirement, it is also possible to arrange more first straight line 12c.
In the embodiment of this utility model compressor movement vibration-proof structure, damping element can be adopted
The parts that can use with any compressor movement or unit construction, the such as bullet shown in Fig. 3
Spring 6, it is also possible to be inflation or the damping element of hydraulic pressure class is stepped on.This spring 6 is connected above spiral shell
Bolt set 9, lower section is by spring strut set 10 installation spring strut 5, and bolt sleeve 9 can overlap
It is located on protuberance 12b.
Owing to have employed aforesaid vibration damping fixed structure, therefore without opening on stator core 4a
If for the mounting groove arranging damping element, therefore can avoid stator core 4a magnetic circuit as far as possible
The adverse effect of trend.Further, as shown in Figure 6, it is also possible to reduce existing stator ferrum
On core 4a, the bolt quantity by hole 4b, changes 4 bolts into two by hole 4b, and
And make two bolts be arranged on stator core 4a by hole 4b, in order to by two bolts 8
Stator core 4a is connected on the installation foot of frame 1.Stator core 4a reduces bolt
Pass through hole, it is possible to improve the magnetic circuit trend of stator core 4a further.Further, if will
The installation foot of frame 1 is arranged on vibration damping fixed structure, such as by bolt by the peace of frame 1
Dress foot is connected with sleeve 12 or shirt rim 12a, so can also be able to make frame 1 and stator ferrum
Core 4a is relatively fixed, and such stator core 4a can save the bolt setting by hole, thus enters
The magnetic circuit trend optimizing stator core of one step.
Further, the outer circumferential profile of preferably stator core 4a is circular, and this also is able to
The magnetic circuit trend making stator core 4a is improved, thus reduces magnetic resistance, reduces loss.Another
In embodiment, the outer circumferential profile of stator core 4a be most two the second straight line 4d and
The shape of part-circular periphery composition.This straight line structure is conducive to single sheet punching press arrangement, saves
Stator core raw materials.If wherein using two the second trimming 4d, it is preferably symmetrical junction
Structure.
Fig. 7 shows the motor contrast signal used under this utility model scheme and original scheme
Figure.With the curve of the less diamond shaped blocks institute matching of size for this programme motor at different electricity in figure
The efficiency eta situation of change of pressure, and the curve of larger-size square dice institute matching is former
Motor efficiency eta situation of change under different voltages, it is seen that when the magnetic circuit of stator core 4a is walked
After being optimized, its magnetic resistance reduces, and iron loss reduces, and effectively improves electric efficiency
2%～3%.After have employed stator core outer circumferential installation damping element, overall installation is high
Degree can decline 5%～15%, and side mounting structure does not results in the magnetic circuit of stator core not
Freely, use during therefore it can be not limited in invariable frequency compressor and frequency-changeable compressor.
Above-mentioned compressor each embodiment of movement vibration-proof structure can be applicable to various types of compact machine core
Needing the occasion of vibration damping, it is possible to be effectively reduced integral installation height, it is applied and compresses at refrigerator
Time in machine, it is possible to make refrigerator product while realizing high energy efficiency, improve the sky of freezing and refrigeration room
Between utilization rate, make outward appearance smaller and more exquisite and attractive in appearance.
Finally should be noted that: above example is only in order to illustrate technical side of the present utility model
Case is not intended to limit；Although this utility model having been carried out specifically with reference to preferred embodiment
Bright, those of ordinary skill in the field are it is understood that still can be to tool of the present utility model
Body embodiment is modified or portion of techniques feature is carried out equivalent；Without deviating from this
The spirit of utility model technical scheme, it all should contain the technology being claimed at this utility model
In the middle of aspects.
