Specific implementation mode

Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein Described specific implementation mode is only used for describing and explaining the present invention, and is not intended to limit the utility model.

In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower, left and right " is usual Refer to upper and lower, left and right shown in refer to the attached drawing；" inside and outside " refers to the inside and outside of the profile relative to each component itself.

Shown in referring to Fig.1, according to a kind of rotary compressor of preferred embodiment of the utility model, including shell 2, electricity Thermomechanical components 3 and compression assembly 4.Shell 2 defines vessel 1, and electric machine assembly 3 and compression assembly 4 are placed in the vessel 1.

Electric machine assembly 3 is located at 4 top of compression assembly, and includes stator 31 and rotor 32, which is sequentially connected and pressure Contracting component 4 (piston), 4 compression refrigerant of compression assembly can be driven.The both ends of stator 32 have by stator coil winding Upper end line packet 31a and lower end line packet 31b, lower end line packet 31b towards 4 direction of compression assembly have extend grow Degree.

In the present invention, compression assembly 4 is fixed on the madial wall of shell 2 by fixed frame 5, the fixed frame 5 Usually have along the part that 2 madial wall of shell upwardly extends, which has an adverse effect to the arrangement of lower end line packet 31b. For this purpose, the rotary compressor of the utility model is formed with the first empty avoiding portion 31c in the lower end outer rim of lower end line packet 31b, and So that minimum spacing between lower end line packet 31b and fixed frame 5 be the first empty avoiding portion 31c and the fixed frame 5 it Between minimum spacing and be not less than predetermined minimum safe distance s.

5 upper end of rotary compressor fixed frame of the utility model does not interfere with the maximum of lower end line packet 31b as a result, Radial dimension, and can allow lower end line packet 31b that there is relatively large axial extension, and avoid and compression assembly Fixed frame interfere, reduce stator line and hinder rate, promote product quality；Alternatively, electric machine assembly 3 can be made to move down, contract Short motor jib-length L, to improve compressor rigidity.

Determine that the predetermined minimum safe distance s of the minimum spacing limiting value between lower end line packet 31b and fixed frame 5 is got over Greatly, more it is unfavorable for improving compressor rigidity.However, predetermined minimum safe distance s determine it is too small, it is required that stringent manufacture and Assembly precision seriously affects manufacture efficiency.For this purpose, predetermined minimum safe distance s is preferably not less than 2.5mm, such as 5mm.

In addition, to ensure higher rigidity, upper end line packet 31a can also be grown in the extension of vertical direction (i.e. axial) Spend the development length for being set greater than lower end line packet 31b in the direction.

Shown in Fig. 1, in a preferred embodiment, compression assembly 4 includes cylinder block 41 and is installed on this Upper bearing (metal) 42 in cylinder block 41, piston eccentric rotary in the compression chamber that the cylinder block 41 limits under the driving of rotor 32.Its In, cylinder block 41 is bolted to fixed frame 5, and compression assembly 4 is fixed to the madial wall of shell 2.

In conjunction with shown in Fig. 2 and Fig. 3, in order to avoid lower end line packet 31b is interfered with fixed frame 5, the first empty avoiding portion 31c can be formed as a variety of suitable structure types.For example, the first empty avoiding portion 31c could be provided as its sectional elevation with respect to water Square to tilt extend, as shown in Figure 2.Wherein it is preferred to which the angle α of the sectional elevation relatively horizontal orientation is not less than 30 °. The first empty avoiding portion 31c provides the space installed within the scope of large error for fixed frame 5 as a result, to allow lower end The axially or radially size bigger or electric machine assembly 3 of line packet 31b moves down.

In another preferred embodiment shown in Fig. 3, the sectional elevation indent of the first empty avoiding portion 31c is formed as recessed Shape broken line or curve.The upper end of fixed frame 5 can be higher than the lower end of lower end line packet 31b as a result, that is, allow lower end line packet 31b has larger axial dimension, thus improves product quality or improves compressor rigidity.

Further, rotary compressor is usually equipped with muffler 43 on upper bearing (metal) 42.For this purpose, in a kind of preferred reality It applies in mode, the second empty avoiding portion 31d can also be formed in the lower end inner edge of lower end line packet 31b.In other words, lower end line packet 31b wound motor power output shafts are arranged and are normally located above the side of muffler 43, can be with to avoid the two from interfering Second empty avoiding portion 31d is provided, hinders electric machine assembly 3 to move down or the increasing of lower end line packet 31b axial lengths to avoid muffler 43 Add.Herein, the second empty avoiding portion 31d is preferably formed so that the minimum spacing between lower end line packet 31b and muffler 43 not More than 2.5mm.

Exemplary illustration has been carried out to rotary compressor provided by the utility model above.On this basis, this practicality It is novel that a kind of air-conditioning system with the rotary compressor is also provided.

Preferred embodiments of the present invention, still, the utility model and unlimited are described in detail above in association with attached drawing In this.In the range of the technology design of the utility model, a variety of simple variants can be carried out to the technical solution of the utility model, It is combined in any suitable manner including each particular technique feature.In order to avoid unnecessary repetition, the utility model Various combinations of possible ways are no longer separately illustrated.But these simple variants and combination equally should be considered as the utility model institute Disclosure belongs to the scope of protection of the utility model.
