Ultimate range between 111 is Dst, for example in the example of fig. 1, in the vertical direction, the upper surface of stator core 21 and the
The distance between one end wall 111 is Dst, needs exist for explanation, when profile of first housing 11 for irregular shape,
Dst is then the ultimate range between the upper surface of stator core 21 and the madial wall of the first housing 11.
Further, compression mechanism 3 is located in housing 1 and positioned at the side away from the first end wall 111 of motor 2, for example
In the example of Fig. 1, compression mechanism 3 can be arranged on the lower section of motor 2, thus compression mechanism 3 compared with motor 2 away from the first end wall
111, and it is easy to installation and the cooperating of motor 2 and compression mechanism 3.
Specifically, with reference to Fig. 1, compression mechanism 3 includes cylinder assembly 31 and base bearing 32, and base bearing 32 is connected to air cylinder group
On one side end face (such as the upper surface of the cylinder assembly 31 shown in Fig. 1) of the neighbouring motor 2 of part 31, in the axial direction of housing 1

The distance between the upper surface of sub- iron core 22 and the top of flange portion 321 of base bearing 32 are Drt.
Wherein, Dst and Drt meet relation：0.335≤Dst/Drt≤0.838, with reference to Fig. 5, needs exist for explanation,
Abscissa in Fig. 5 represents the value of Dst/Drt, and the ordinate α in Fig. 5 represents noise OA when rotary compressor 100 works
Value, specifically, with the continuous increase of Dst/Drt, the operating noise OA values of rotary compressor 100 are first gradually lowered to necessarily
Degree, then gradual increase again, by the different designs of the Dst/Drt ratios to rotary compressor 100, can cause rotation
Formula compressor 100 has different noises, for example, when Dst/Drt is 0.4,0.45,0.55,0.6,0.75, rotary compressor
100 operating noise can be all effectively reduced.
It follows that being set to by by the Dst/Drt values of rotary compressor 100：0.335≤Dst/Drt≤
0.838, can all be effectively reduced the operating noise of rotary compressor 100.
Explanation is needed exist for, motor 2 and compression mechanism 3 can be coaxially disposed with housing 1, that is to say, that bent axle 4
Central axis and housing 1 central axes so that the central axis weight of the rotation axis of rotor core 22 and housing 1
Close, the central axis of base bearing 32 and the central axis of cylinder assembly 31 also with the central axes of housing 1, so, can
So that rotary compressor 100 is simple and reasonable, and it is easy to the assembling of rotary compressor 100.
Rotary compressor 100 according to embodiments of the present invention, rational scope is arranged on by by the value of Dst/Drt
It is interior, noise when rotary compressor 100 works can be effectively reduced so that rotary compressor 100 is closed with simple structure
The advantages of managing, assemble simply and be effectively reduced noise.
Preferably, Dst and Drt further meet relation：0.568≤Dst/Drt≤0.680, for example, when Dst/Drt is
0.58th, 0.6 or 0.65 when, the operating noise of rotary compressor 100 close to minimum, it follows that by by rotary compression
The Dst/Drt values of machine 100 are set to：0.568≤Dst/Drt≤0.680, can further reduce rotary compressor 100
Operating noise.
In some embodiments of the invention, with reference to Fig. 1 and Fig. 2, from the refrigerant meeting of the HTHP of the discharge of compression mechanism 3
Upwards transmission, the passage 221 being formed through on rotor core 22, thus can be easy to the refrigerant of HTHP to upload
It is dynamic, reduce noise.
Further, the central axis of passage 221 is parallel with the rotation axis of rotor core 22, for example showing in Fig. 1
In example, the rotation axis of rotor core 22 is above-below direction, so that the central axis of passage 221 can also be above-below direction,
So as to further be easy to the upward transmission of the refrigerant of HTHP, noise is effectively further reduced.
In some embodiments of the invention, first diameter of the passage 221 on rotor core 22 is axisymmetricly distributed,
Width D of the passage 221 in the first diametric(al) meets：0.204mm≤D≤0.480mm, for example in the figure 2 example, leads to
Stomata 221 can be on rotor core 22 the first diameter k be symmetrical arranged, width of the passage 221 on the first diameter k be D, ginseng
Fig. 6 is examined, explanation is needed exist for, the abscissa in Fig. 6 represents the value of D, and the ordinate α in Fig. 6 represents rotary compressor
Noise OA values during 100 work, specifically, as the continuous change of D values is big, the operating noise of rotary compressor 100 first gradually drops
It is low then gradually to increase again to a certain extent, set by the difference of the D values of the passage 221 to rotary compressor 100
Meter, can cause that rotary compressor 100 has different noises, for example, when D is 0.25mm, 0.35mm, 0.41mm, rotatably
The operating noise of compressor 100 can be all effectively reduced.
It follows that being set to by by the D values of the passage 221 of rotary compressor 100：0.204mm≤D≤
0.480mm, can be effectively reduced the operating noise of rotary compressor 100.
Preferably, D further meets：0.404mm≤D≤0.460mm, for example, when D be 0.41mm, 0.43mm or
During 0.45mm, the operating noise of rotary compressor 100 close to minimum, it follows that by by the logical of rotary compressor 100
The D values of stomata 221 are set to：0.404mm≤D≤0.460mm, the work that can further reduce rotary compressor 100 is made an uproar
Sound.
In some embodiments of the invention, the contour line of the cross section of passage 221 can be formed as curve or straight line
And the combination of curve, for example, the cross section of passage 221 can be hollow arc shape (as shown in Figure 2), or circular
(as shown in Figure 3), can also be round rectangle (as shown in Figure 4), consequently facilitating the circulation of the refrigerant of HTHP, reduces
The operating noise of rotary compressor 100.Certainly, the invention is not restricted to this, the cross section of passage 221 can also be that other are bent
The combination shape of line or straight line and curve, preferably to meet actual use demand.
In some embodiments of the invention, it is (such as upper and lower shown in Fig. 1 in the rotation axis direction of rotor core 22
Direction) on, the shape of cross section of passage 221, size all same, so as on the one hand be easy to the processing of passage 221, reduce rotation
The complex manufacturing of rotary compressor 100, on the other hand may be such that the refrigerant of HTHP when by passage 221
Flowing is more uniform, enters the operating noise of ground reduction rotary compressor 100.
In some embodiments of the invention, with reference to Fig. 2, passage 221 can be for multiple and in the week of rotor core 22
It is evenly spaced apart upwards, that is to say, that multiple passages 221 are evenly spaced apart setting in the circumference of rotor core 22,
So as to facilitate the processing of passage 221, and it is easy to the circulation of HTHP refrigerant.
Further, with reference to Fig. 2-Fig. 4, the shape of each passage 221, size all same, so as to further facilitate
The processing of passage 221, improves the circulation uniformity of HTHP refrigerant, and then is effectively reduced rotary compressor 100
Operating noise.
In some embodiments of the invention, with reference to Fig. 1, rotor core 22 is rotatably arranged at the interior of stator core 21
Side, specifically, the periphery wall of stator core 21 can be fixed with the internal perisporium of housing 1, and rotor core 22 can be with the warm of bent axle 4
Set is connected, and so as to effectively improve the fitment stability of motor 2 and compression mechanism 3, and is easy to the dress of rotary compressor 100
Match somebody with somebody.Certainly, the invention is not restricted to this, rotor core 22 can also rotationally be located at the outside of stator core 21.
