Description

Silencer for Hermetic Compressor and Hermetic Compressor with it

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric compressor used in a refrigeration cycle including a refrigeration air conditioner and driven by an electric motor. In particular, the present invention reduces noise during operation in a hermetic compressor formed by storing a compressor or an electric motor in a hermetic container. An improved hermetic compressor silencer and hermetic compressor having the same.

Conventionally, a so-called hermetic compressor is widely used in an electric compressor used in a refrigeration cycle including a refrigeration air conditioner. This hermetic compressor comprises an electric motor element 2 comprising a stator 2a and a rotor 2b inside a hermetically sealed container 1 for storing lubricating oil 100 at the bottom as shown in FIGS. 12 and 13. And a frame having a bearing portion for rotatably supporting the crankshaft 7 for the compressor element 60 including the cylinder 3, the piston 4, the cylinder head 5, the head cover 6, and the like ( The compressor main body which is arrange | positioned above and below each of 8) is supported and accommodated through the elastic body 9, such as a spring. Therefore, in such a hermetic compressor, several spaces are formed between the hermetic container 1 and the compressor main body. That is, the inside of the hermetic container 1 includes two spaces 10-1 surrounding the compressor main body in the horizontal direction and two hemispherical spaces 10-2 including the space extending in the vertical direction. Space is formed. One end of the connecting pipe 11 is connected to the suction port provided in the cylinder head 5 of the compressor element 60 via the head cover 6, and the other end of the connecting pipe 11 is sealed. A silencer 13 for silenced the suction noise of the gas refrigerant having the suction unit 20 opened inside the container 1 is coupled.

In the hermetic compressor having such a structure, when the crankshaft 7 is rotated by the electric motor element 2, the piston 4 passes through the slider 41 by the eccentric motion of the crank pin 71 of the compressor element. 3) Reciprocate inside and repeat the suction, compression, and discharge strokes. In the suction stroke of the piston 4, the refrigerant gas filled in the space in the sealed container 1 is sucked from the opening of the suction part 20, and the silencer 13, the connection pipe 11, and the head cover 6 are filled with the refrigerant gas. A suction valve which closes the suction port of the cylinder head 5 via a suction flow passage consisting of the slide passage is pushed open and flows into the cylinder 3. The silencer 13 is provided for the purpose of making noise of the vibration of the suction valve generated during the suction stroke and the pulsation of the refrigerant gas to be sucked.

In addition, in the silencer 13 as shown in FIG. 14, the refrigerant gas flows from the suction unit 20 of the silencer 13 and is connected to the outlet of the silencer 11 via the suction passage 12. 11) and is then sucked into the cylinder 3 via the cylinder head 5. In addition, only one so-called resonance chamber 21 is provided in this silencer 13, and a resonance hole 21 for communicating with the resonance chamber 21 is opened in the middle of the suction passage 12 through this. . According to this configuration, the silencer 13 acts to silence the low frequency sound generated as the vibration sound of the intake valve of the cylinder head 5 or the pulsation sound of the refrigerant gas by the resonance chamber 21. In addition, the structure of the silencer in such a compressor has already been understood, for example, in Japanese Patent Laid-Open No. 58-15605, Japanese Patent Laid-Open No. 64-12086 and Japanese Patent Laid-Open No. Hei 6-74153. Known.

According to the hermetic compressor of the related art configured as described above, the vibration sound of the suction valve and the pulsation sound of the gas in the suction stroke due to the structure can make noise in the frequency band of a part of the specific region. However, when two or more space parts are formed between the sealed container 1 and the compressor main body accommodated therein, and a specific standing wave (columnar resonance) exists in each of these spaces. Noise in the frequency band that is not sufficiently silenced by the silencer generates resonance, thereby increasing the operation noise of the hermetic compressor. The most remarkable resonance among them is the resonance occurring in the space 10-1 formed around the compressor main body as described above, and one wavelength is a sound having a frequency equal to the average circumferential length of the space. For example, according to an experiment by the present inventors, the sound in the frequency band of about 400 Hz generates resonance, which is amplified and becomes noise. Also in the hemispherical space 10-2 extending upward from the periphery of the compressor main body, sound in the frequency band of about 600 Hz is generated as a noise due to resonance.

In addition, the noise maintaining the resonance is mainly emitted from the suction unit 20 of the muffler (13). However, the silencer 13 in the prior art has only been designed to be installed in a narrow space from the viewpoint of miniaturization and compactness of the compressor, and it is not always sufficient to reduce the noise in the frequency band generating these resonances. . Moreover, the silencer 13 in the said prior art did not reduce this corresponding to the resonance frequency which generate | occur | produces in several spaces 10-1 and 10-2 in the hermetic container 1 of the hermetic compressor. .

In addition, in the conventional silencer 13, only one resonance chamber 21 connected in the middle of the suction part 20 is formed separately from the silencer 13, and this is a passage for gas refrigerant 12 It has a structure attached to the wall surface of the muffler 13 to form a, thereby increasing the number of parts of the muffler 13 and its manufacturing process also increases.

Therefore, the object of the present invention has been made in view of the above-mentioned problems in the prior art, and in the suction part 20 of the muffler 13 which is a sound source of such resonance according to the above-mentioned examination and recognition by the inventors. By reducing the vibrations and pulsations of a specific frequency band radiated in consideration of the resonance caused by the various spaces formed in the sealed container, it is possible to greatly reduce the noise generated by the resonance in the sealed container. It is to provide a silencer for a compressor, and to provide a quiet hermetic compressor by drastically reducing operation noise using such a silencer.

Another object of the present invention is to provide a silencer for a hermetic compressor which can be more stably assembled with a relatively small number of processes.

In the drawing, reference numeral 17 denotes a first throttle portion, and the throttle portion 17 is formed by a gap between a part of the bent partition plate 15 and the wall surface forming the cavity portion 14, The cavity 14 and the first volume chamber (resonance chamber) 16 communicate with each other via the throttle portion 17. This 1st volume chamber (resonance chamber) 16 comprises the 1st resonance silencer 18 which is a resonator with the said throttle part 17. As shown in FIG.

Next, reference numeral 12 in FIG. 2 shows the end of the suction passage 12 provided in the silencer 13, and the end of the suction passage 12 defines the divided cavity 14 of the silencer 13. Communicating with In addition, the passage 12 of the suction refrigerant gas is composed of a horizontal portion 12-1 and a vertical portion 12-2 in the silencer 13, as shown in FIG. It forms a curved bent tube. In addition, the suction part 20 formed at the other end of the passage 12 is opened in the sealed container 1, and is supplied from a refrigeration cycle such as a refrigeration air conditioner through this, and the refrigeration filled in the sealed container 1 is filled. The gas is inhaled.

In the figure, reference numeral 21 denotes a second volume chamber, which is a hollow chamber (resonance chamber) formed by being surrounded by the wall of the passage 12 of the bent pipe and the outer wall of the silencer 13, and the like. 22 is a hole formed in the suction passage 12 of the refrigerant gas, in particular, in the wall of the horizontal portion 12-1, and as shown in the drawing, the hole 22 opens the passage 12 in a second volume chamber ( 21) in communication with the second throttle portion. In addition, in the figure, the 2nd resonance type silencer (resonator) comprised by these 2nd volume chamber 21 and the 2nd throttle passage 22 is shown by (23).

Thus, the first silencer (resonator) 18 and the second resonance silencer (resonator) along the suction passage 12 and the cavity 14 through which the sucked gas refrigerant passes through the silencer 13. The first resonance chamber (volume chamber) 16 and the second resonance chamber (volume chamber) 21 forming the (23) are the first throttle portion 17 and the second throttle portion (hole) 22, respectively. It is structured to communicate through.

However, in such a resonant silencer, the frequency f of noise that can be silenced in general is determined by the volume V of the volume chamber which becomes the resonant chamber of the muffler, the cross-sectional area S and the length L of the throttle part, and the frequency f is expressed as follows. Lose.

[Equation 1]

Here, C is the sound speed in the suction passage.

Therefore, in the present invention, the noise frequencies f1 and f2 of the first resonance silencer 18 and the second resonance silencer 23 are resonance spaces 10-1 and 10-2 in the sealed container 1, respectively. Adjust to suit the resonance frequency of. Specifically, in the above embodiment, the volume V1 of the first volume chamber (resonance chamber) 16 of the first resonance silencer 18 and the cross-sectional area S of the throttle portion 17 and the length L thereof (see Fig. 2). By appropriately adjusting the noise frequency, the noise frequency is adjusted to the frequency band (for example, about 400 Hz) of the resonance space 10-1 in the sealed container 1. On the other hand, the volume V2 of the second volume chamber (resonance chamber) 21 of the second resonance silencer 23 and the cross-sectional area S and its length L of the throttle portion 22 (in this case, the wall of the passage 12) The noise frequency is adjusted to the other frequency band (for example, about 600 Hz) of the resonance space in the sealed container 1 by appropriately adjusting the thickness).

Subsequently, a more specific structure of the muffler 13 explained the principle of operation will be described in detail with reference to FIGS. 4 to 8.

In addition, the silencer 13 shown in these figures can be formed with a metal material or a resin material. However, here, especially, it is formed by the heat insulating resin material. Thus, by forming the silencer 13 from the resin material, it is possible to manufacture relatively easily or inexpensively by injection molding, etc., and also improve the performance as a whole hermetic compressor by the heat insulation function.

As shown in Fig. 6, the silencer 13 is constituted by three components, (13-A) and (13-B), and (13-C) (shown in Fig. 8) provided therein. . By assembling these, unlike the prior art, several volume chambers (resonance chambers) can be manufactured integrally and easily in the silencer 13 easily.

The silencer 13 according to this embodiment has the embodiment shown in FIG. 1 in the shape of the connecting pipe 11 connected to the cylinder head 5 of the compression mechanism element of the compressor main body or the shape of the suction part 20 thereof. Although somewhat different from the example, it also has a connection pipe 11 and a suction part 20 of the refrigerant gas opened in the sealed container 1. In the middle of the passage from the suction part 20 to the outlet of the connecting pipe 11, a volume chamber (resonance chamber) for forming two resonance silencers is also provided, whereby the suction stroke of the compression mechanism element is provided. The noise generated by the vibration of the suction valve and the pulsation of the refrigerant gas is generated.

That is, as is clear from these figures, the cavity 14 of the muffler 13 which is continuous to the cylinder head 5 of the compression mechanism element 60 via the connecting pipe 11 is continuous with the cavity 14. A suction passage 12 composed of a horizontal portion 12-1 and a vertical portion 12-2 is formed between the suction portions 20 opened in the sealed container 1. In addition, a second volume chamber (resonance chamber) 21 is formed by the suction passage 12 of the suction gas refrigerant and the wall outside the silencer 13, and the second volume chamber (resonance chamber) 21 is formed. Is in communication with the suction passage 12 via a hole 22 which is a second throttle portion formed in a part of the wall of the horizontal portion 12-1 of the suction passage 12.

In addition, as shown clearly in FIGS. 7 and 8 attached to the cavity 14 formed in the substantially crescent shape of the upper portion of the muffler 13 is also a component forming the cavity 14 as described above. The partition plate 15 which protrudes integrally from the partition 13-C and is bent in the shape of an "L" shape is provided, and the 1st volume chamber (resonance chamber) 16 is cavity by this. In the portion 14 is the membrane. In addition, (17) has shown the throttle part of the 1st volume chamber (resonance chamber) 16 formed also by the bending part of the said partition board 15. As shown in FIG.

The noise characteristic by the silencer 13 of the structure demonstrated above is shown in FIG. In the graph of this figure, the characteristic curve N is the level of noise from the compressor element which is the sound source, whereas the characteristic curve I is reduced by the noise function of the silencer 13, that is, the silencer ( The level of the noise emitted from the suction port 20 of 13) is shown. As is also clear from this graph, according to the silencer 13, the sound reduction (indicated by RD in the figure) represented by an arrow in the graph in the figure is remarkable in the frequency f1 near 400 Hz and the frequency f2 near 600 Hz and the frequency band therebetween. It can be seen that. As a result, in the hermetic compressor in which the silencer 13 is attached to the compression mechanism, the noise of the frequency around 400 Hz to 600 Hz is selectively reduced, and despite the existence of several resonance spaces in the sealed container 1, The resonance in the sealed container 1 does not occur, and a quiet sealed compressor can be obtained. In addition, here, for the sake of comparison, the characteristics of the conventional silencer are indicated by characteristic curve III.

In the above description, it has been explained that there are two spaces for generating standing waves at the frequency f1 near 400 Hz and the frequency f2 near 600 Hz in the sealed container 1 of the hermetic compressor. Even when there is a space to be made, the generation of noise at these other frequencies can be greatly suppressed by setting the frequencies f1 and f2 such that these other frequencies are located between the frequencies f1 and f2.

In addition, in the above embodiment, as the partition plate 15 forming the first volume chamber (resonance chamber) 18 by dividing the cavity 14 formed in the substantially crescent shape, the above-mentioned FIG. 1, FIG. 7 and FIG. Only the member whose outer shape shown in this figure was bent in substantially "L" shape was demonstrated. However, according to the present invention, the partition plate is, for example, in the shape shown by (15 ') in FIG. 10 attached thereto, and the opening area S of the throttle portions 17-1 and 17-2 can be increased. Alternatively, the resonance chamber may be partitioned by a flat member instead of the curved partition board 15, which is not shown, and an opening having a desired size may be provided in the flat member.

In the above embodiment, the volume V of the volume chamber (resonance chamber), for example, is used to adjust the frequency f of noise that can be noised by the first resonance silencer 18 and the second resonance silencer 23. Or although adjusting the cross-sectional area S of the throttle part was demonstrated, Especially in the 1st resonance silencer 18, in adjusting the length L of the throttle part according to the length of the bending part of the said "L" shaped partition board 15, The adjustment is possible, too. In the second resonance silencer 23, for example, as shown in Figs. 4 and 8, the second throttle opened in a part of the wall forming the horizontal portion 12-1 of the intake passage 12. It is also possible to form the part 22 by protruding in the volume chamber 21, and to adjust the length L of the throttle part according to the length of this protrusion part.

In addition, in the above embodiment, as shown in Figs. 4 to 8, the silencer 13 is constructed by assembling three components indicated by (13-A), (13-B) and (13-C). . However, in order to sufficiently achieve the noise effect by the first resonance silencer 18 and the second resonance silencer 23 during its assembly, the sealing of the resonance chambers 16, 21 formed between these members is necessary. It is important. Therefore, in the said embodiment, especially between the component 13-C and the component 13-B is melt-bonded by adhesive bonding or high frequency heating. In addition, it is important to reliably bond the upper end surface to the inner bottom surface of the component 13-A or to the inner side surface of the component 13-B also for the partition plate 15 formed on the component 13-C.

To that end, as shown in FIG. 11, the recess 110 is provided on the surface of one member (for example, the inner bottom surface of the component 13-A), and the other projection (for example, inside) is provided. For example, the partition plate 15 is accommodated (FIG. 11A), or two rows of convex portions 111 and 111 are formed and formed between the two rows of convex portions 111 and 111. The other protrusion part (for example, the partition board 15) may be accommodated in the inside of the recessed part 112 used (FIG. 11 (b)). Alternatively, the tip of the protrusion (for example, the partition plate 15) is made thin to form the elastic portion 15-1. For this purpose, the flat portion (for example, the inner surface of the component 13-A) is pressed and adhered closely. It is also possible to fix. In addition, the noise characteristic of the muffler 13 in the case where the sealing between components mentioned above is not enough, that is, when leakage occurs, is shown by the characteristic curve II in FIG. 9, and this also makes clear that In this case, the superiority to the characteristic III of the conventional silencer cannot be found with respect to the noise in the frequency band in the vicinity of about 400 Hz to 600 Hz, which is particularly problematic as the noise.

In the above embodiment, the resonance frequencies f1 and f2 of the first space 10-1 and the second space 10-2 in the sealed container 1 are described as 400 Hz and 600 Hz, respectively. The frequency changes depending on the size of the sealed container 1 and the like, and in this case, the resonance frequencies f1 and f2 also change. Therefore, f1 and f2 of the noise characteristics of the muffler 13 may be changed appropriately. .

As is clear from the above detailed description, according to the hermetic compressor silencer and the hermetic compressor provided with the same, the first resonance of the silencer attached to the compressor element even when there is a space for generating several resonance frequencies in the hermetic container. For the hermetic compressor which can greatly suppress the noise in the frequency band around 400Hz to 600Hz, which is a problem as noise by the action of the type silencer and the first resonance type silencer, and prevent resonance in the sealed container. By providing a silencer and employing it in a hermetic compressor, it becomes possible to provide a hermetic compressor capable of quiet operation.
