Abstract
The present invention relates to a base of a hermetic type rotary compressor. The hermetic type rotary compressor comprises a sealed shell body and an electric motor, wherein the electric motor is composed of a rotor and a stator. A rotary shaft is inserted in a shaft hole of the center of the rotor, the lower end part of the rotary shaft is provided with an eccentric part, the outside of the rotary shaft is provided with a piston, and then a compression space is formed. A compression mechanical part which is composed of a cylinder body, an upper bearing and a lower bearing is arranged on the compression part. The bottom of the sealed outer shell is connected with a base. The base is composed of two plane surfaces of which the cross sections are respectively in a shape likes Chinese character 'hui' in an opening way, and the two plane surfaces respectively form a triangle shape. As the base adopts a double plane surface type in a 'hui' shape, the surrounding sound fields of the smooth compressor are directly diffused, a free field is formed, and the present invention can reduce noise, and effectively eliminate the occurrence of the high frequency noise on the bottom of the compressor. In addition, the present invention is fixed by connecting holes corresponding to the double plane surfaces in the 'hui' shape, which is equivalent to a spring. Thus, the vibration is favorably reduced, and the noise is decreased.
Description
Technical field
The invention belongs to hermetic rotary compressor base frame, particularly relate to and a kind ofly can reduce noise, reduce the hermetic rotary compressor base frame of vibration.
Background technique
At present the structure of hermetic rotary compressor as shown in Figure 1, the motor 4 that it comprises seal casinghousing 1, is made of rotor 2 and stator 3; Running shaft 5 is inserted among the axis hole 2a of rotor center, and there is eccentric part 6 the running shaft underpart, and there is piston 7 in its outside, for forming compression volume 8, the compression mechanical portion 12 that is made of cylinder body 9 and upper and lower bearing 10,11 is housed; The seal casinghousing bottom is connected on the base 13.
The base of prior art such as Fig. 2, shown in Figure 3, base have three circular arc lugs 14, and be middle dented, is subtriangular discoid body.There is macropore the centre of discoid body, and compressor welds together by this hole and base.On three lugs aperture 15 is arranged, aperture is that base is fixedlyed connected with air conditioner and used the hole.
This discoid body base is the casting global formation, forms a plurality of delivering in discoid body bottom surface and lug jointing place, produces vibration and noise when compressor operating, and the base that fuses with compressor also vibrates, and produces resonance.Run into base rotation angle disk wall back reflection after the noise sound wave of compressor spreads out of and return, the noise sound wave that sends again with compressor intersects, and produces to disturb, and forms complicated sound field, makes noise increase like this,
In addition, after compressor and the base welding, the fixedly connected distance with aperture on three from the compressor housing outer rim to base lugs of easy appearance is different, varies, and difference is big, can not guarantee that distance is identical.Distance is different, and the ET difference that the noise that sends from compressor reflects intersects, and noise is increased.
Summary of the invention
The present invention can reduce noise for the technical problem that exists in the solution known technology provides a kind of, reduces the hermetic rotary compressor base frame of vibration.
The present invention for the technological scheme that solves the technical problem that exists in the known technology and take is: hermetic rotary compressor base frame of the present invention, and the structure of hermetic rotary compressor comprises: seal casinghousing, the motor that is made of rotor and stator; Running shaft is inserted in the axis hole of rotor center, and there is eccentric part the running shaft underpart, and there is piston in its outside, for forming compression volume, the compression mechanical portion that is made of cylinder body and upper and lower bearing is housed; The seal casinghousing bottom is connected on the base; Base is a hollow tri-prism, and this cylinder is two layer planes shape triangular in shape up and down, and two-layer up and down planar central all has circular open.
Three angles of described two-layer plane trigonometry shape are respectively equipped with corresponding attachment hole on two layer planes
Advantage and good effect that the present invention has are: hermetic rotary compressor base frame of the present invention, because base adopts hollow two layer plane tri-prisms up and down, smoothly, no protruding end, sound field around the no corner, compressor directly spreads, and forms free field, so can reduce noise, can effectively eliminate the generation of compressor bottom high frequency noise.
Have, the base of this structure and the welding of compressor can guarantee mutual alignment between them again, make compressor equate that with each fixed connection point distance sound field is orderly, have so also reduced noise.
In addition, adopt hollow two layer plane respective apertures to fix, be equivalent to spring, help reducing vibration, reduce noise.

Fig. 4 is a base plan view of the present invention;
Fig. 5 is the B-B sectional view.
Embodiment
It is following that the present invention will be described in detail with reference to drawings and Examples: hermetic rotary compressor base frame of the present invention, the structure of hermetic rotary compressor as shown in Figure 1, it comprises: seal casinghousing 1, the motor 4 that is made of rotor 2 and stator 3; Running shaft 5 is inserted among the axis hole 2a of rotor center, and there is eccentric part 6 the running shaft underpart, and there is piston 7 in its outside, for forming compression volume 8, the compression mechanical portion 12 that is made of cylinder body 9 and upper and lower bearing 10,11 is housed; The seal casinghousing bottom is connected on the base 13.
As Fig. 4, shown in Figure 5, base is a hollow tri-prism, and this cylinder is two layer planes shape triangular in shape up and down, and two-layer up and down planar central all has circular open.
Three angles of two-layer plane trigonometry shape are respectively equipped with corresponding attachment hole 16 on two layer planes.Attachment hole is that base is fixedlyed connected with air conditioner and used the hole.
Hermetic rotary compressor base frame of the present invention, level and smooth because base adopts hollow two layer plane tri-prisms up and down, the sound field around the compressor directly spreads, and forms free field, so can reduce noise, can effectively eliminate the generation of compressor bottom high frequency noise.
In addition, adopt hollow two layer plane respective apertures to fix, be equivalent to spring, help reducing vibration, reduce noise.
