[0024] FIG. 5 is a perspective view showing a suction silencer and

DETAILED DESCRIPTION
[0025] Hereinafter, embodiments will be described with reference to
the accompanying drawings. In the following description and
drawings, the same reference numerals are used to designate the
same or similar components, and so repetition of the description on
the same or similar components will be omitted.
[0026] FIG. 1 shows an appearance of a suction silencer, and FIG. 2
shows a suction device of working fluid. In these FIGS. 1 and 2,
the suction silencer 1 includes an upper body 4 and a lower body 3
in which space is provided where working fluid flows and noises are
removed.
[0027] Disposed on one side of the upper body 4 or the lower body
3, is a communication pipe 5 communicating with the inside and
outside of the body, to which pipe a connector 6 is installed. The
connector 6 serves to guide the working fluids flowing in the
compressor into the internal space of the suction silencer 1.
Particularly, the connector 6 is made in a bellows type and is able
to be deformed to some extent, and as shown in FIG. 2, comes into
contact with an inner face of a hermetic vessel 8. The connector 6
is provided such that an inlet portion thereof is relatively wide
and the other portion communicating with the communication pipe 5
is relatively narrow. Thus, even when the suction silencer 1 moves
to some extent, the connector allows working fluids to flow inside
through the communication pipe 5.
[0028] On the suction silencer 1, an ejection port 7 is provided
that selectively communicates with the compression chamber through
a valve assembly. The ejection port 7 is a portion for ejecting, to
the compression chamber, working fluids having flowed through the
suction silencer 1.
[0029] The suction silencer constructed as above is mounted in a
cylinder together with the valve assembly, a head cover assembly
and the like, and the connector 6 is installed so that a leading
end thereof comes into close contact with the inner face of the
hermetic vessel where a suction pipe 9 is connected.
[0030] However, although the bellows type connector 6 comes into
close contact with the inner face of the hermetic vessel 8, much
unevenness is formed on a passage in which working fluids flow,
thereby deteriorating the fluidity of the working fluids. Further,
the connector 6 is installed so as to protrude toward the inner
face of the hermetic vessel 8 confronting the front face of the
cylinder where the suction silencer 1 is mounted, that is, the
connector 6 is installed in front of the suction silencer 1, so
that the hermetic vessel 8 is elongated in that direction.
[0031] FIG. 3 is an exploded perspective view of a hermetic
compressor employing a suction device of working fluids according
to a preferred embodiment of the invention, FIG. 4 is a partial
sectional view of the construction of the silencer and connector,
and FIG. 5 is a perspective view showing a suction silencer and a
connector as embodied and broadly described herein.
[0032] Referring to these drawings, an appearance of the compressor
consists of a lower vessel 10 and an upper vessel 12. The lower
vessel 10 and the upper vessel 12 are coupled to each other to form
therein a hermetic space. The vessels 10 and 12 each are formed in
a substantially semi-spherical shape so that inner faces or outer
faces thereof are curved. Inside the hermetic space, parts
constituting the compressor are installed. Under the lower vessel
10, a mounting plate 14 is installed. The mounting plate 14 is
fixed in a position where the compressor is installed.
[0033] Next, a pipe is installed on the lower vessel 10 to allow
working fluids to flow between the inside and outside of the
hermetic space. That is, a suction pipe 16 is installed through the
lower vessel 10 to transfer working fluids into the hermetic space.
An ejection pipe 18 is installed through the lower vessel 10
opposite to the suction pipe 16. A reference numeral 19 is a
process pipe. The process pipe 19 is a passage for injecting oil or
working fluids into the hermetic space, if needed.
[0034] Inside the hermetic space, a frame 20 is supported on the
bottom face of the lower vessel 10 by an elastic member (not
shown). The frame 20 is provided with various parts constituting a
compressor. A motor 22 is provided in the frame 20. The motor 22
consists of a stator 23 and a rotor 24. The rotor 24 rotates in the
stator 23 with electromagnetic interaction with the stator 23.
[0035] A compressing device 25 is installed on the frame 20. The
compressing device 25 compresses working fluids using power of the
motor 22 received via a crank shaft 26.
[0036] The compressing device 25 is provided with a valve assembly
27 for transferring working fluids between the inside and the
outside of a compression chamber, and a head cover 28 forming a
passage of working fluids flowing through the valve assembly 27. A
suction silencer 30 is mounted on a cylinder block, together with
the valve assembly 27 and the head cover 28. The suction silencer
30 transfers the working fluids transferred from outside of the
compressor to the compression chamber, and removes noises of the
valve assembly 27.
[0037] The suction silencer 30 is formed by coupling a lower body
31 and an upper body 32 with each other. Inside the suction
silencer 30, a space is provided in which a certain passage is
formed, so that working fluids enter the compression chamber with
an optimized state, and noises generated from the compression
chamber side, i.e., the valve assembly 27 and the like, are
reversely transferred and reduced.
[0038] The suction silencer 30 is provided, on its one lower side,
with a communication pipe 33. The communication pipe 33
communicates with the inside and outside of the lower body 31. A
connector 34 is connected to the communication pipe 33. The
connector 34 is made of an elastic material. The elastic material
may be, for example, rubber.
[0039] The connector 34 is provided with a connector pipe 35
connected to the communication pipe 33. The connector pipe 35 is
connected with the communication pipe 33 such that its inner
diameter face comes into close contact with the outer diameter face
of the communication pipe 33.
[0040] An enlarged-diameter part 36 is provided so as to be
inclined at a certain angle with respect to the extending direction
of the connector pipe 35. That is, the connector pipe 35 and the
enlarged-diameter part 36 have center lines intersecting with each
other at a certain angle. Such inclination of the enlarged-diameter
part 36 with respect to the connector pipe 35 is for making the
connector 34 positioned on the side of the suction silencer 30.
Since the enlarged-diameter part 36 is inclined to the connector
pipe 35 at a certain angle, it is shaped corresponding to the
curved shape of the lower vessel 10. The connector 34 shaped as
above can come into close contact with an inner face of the lower
vessel 10.
[0041] In the present embodiment, as shown in FIG. 4, the connector
pipe 35 is connected to the communication pipe 33 provided on the
lower side of the suction silencer 30, and the enlarged-diameter
part 36 has an enlarged diameter and extends toward the rear side
of the communication pipe 33. In addition, the enlarged-diameter
part 36 extends corresponding to the curved face of the hermetic
vessel.
[0042] With the structure of the connector 34, even when the
suction pipe 16 passing through the lower vessel 10 is not in a
coaxial line with the communication pipe 33, the connection
therebetween is easily implemented. That is, the connector 34 makes
it possible to connect the suction pipe 16 and the communication
pipe 33 that are not on the same axial line.
[0043] The enlarged-diameter part 36 has an enlarged diameter and
extends from a leading end of the connector pipe 35 toward the
suction pipe 16. That is, a cross-section of the enlarged-diameter
part 36 gradually increases toward the inner face of the lower
vessel 10. Thus, the enlarged-diameter part 36 has a relatively
small diameter at its portion connected to the connector pipe 35.
The diameter thereof gradually increases as it extends away from
the connector pipe 35. In this embodiment, the enlarged-diameter
part 36 is provided such that the diameter thereof sharply
increases at a portion connected to the connector pipe 35, and
gradually increases after that portion.
[0044] The enlarged-diameter part 36 is provided with a contact
skirt 37 at its leading end. The contact skirt 37 is a portion that
comes into contact with the inner face of the lower vessel 10. The
contact skirt 37 is shaped so as to sharply enlarge from the
leading end of the enlarged-diameter part 36, so that its inner
face comes into close contact with the inner face of the lower
vessel 10. The contact skirt 37 allows working fluids entering
inside the hermetic vessel through the suction pipe 16 to flow in
the suction silencer 30 without leakage.
[0045] Meanwhile, an ejection portion 38 is provided in the middle
of the upper face of the upper body 32. The ejection portion 38
serves to transfer working fluids having flowed through the suction
silencer 30 to the compression chamber. Of course, through the
ejection portion 38, noises generated from the valve assembly 27
and the like are transferred into the suction silencer 30. The
ejection portion 38 is a portion for allowing the suction silencer
30 to be coupled with the valve assembly 27 side, and is mounted on
the front face of the cylinder together with the valve assembly 27
by the head cover 28.
[0046] Description will now be made of the operations of the
connector of the hermetic compressor and the suction device of
working fluids using the same in accordance with embodiments as
broadly described herein.
[0047] When the compressor is driven, power is supplied to the
motor 22 to rotate the rotor 24 and then a crank shaft 26. When the
crank shaft 26 is rotated, the compressing device 25 is driven to
compress working fluids.
[0048] That is, when a piston is moved to a bottom dead point in
the compression chamber, working fluids are sucked from the suction
silencer 30 to the compression chamber. Such suction force is
motive power for sucking working fluids from the outside to the
inside of the compressor.
[0049] Thus, the working fluids are sucked into the hermetic vessel
through the suction pipe 16. The working fluids sucked into the
hermetic vessel through the suction pipe 16 are not leaked through
the connector 34 because the inner face of the contact skirt 37 of
the connector 34 is in close contact with the inner face of the
hermetic vessel so that they are transferred to the communication
pipe 33 through the enlarged-diameter part 36 and the connector
pipe 35. The working fluids transferred to the communication pipe
33 pass through the inside of the suction silencer 30 and escape
outside through the ejection portion 38. That is, the working
fluids flow in the compression chamber through the ejection portion
38.
[0050] Meanwhile, the connector 34 allows working fluids to
smoothly flow without hindrance because there is no protrusion on
the inner face thereof. The contact skirt 37 comes into close
contact with the inner face of the hermetic vessel, so that the
working fluids introduced through the suction pipe 16 can be
transferred to the suction silencer 30 without leakage.
[0051] Further, even when the suction silencer 30 is agitated due
to vibrations of the frame 20 upon operation of the compressor,
working fluids can be securely transferred to the suction silencer
30. This is because the connector 34 itself is made of an elastic
material, and particularly, the contact skirt 37 is variably
adhered to the inner face of the hermetic vessel, thereby
effectively preventing leakage of working fluids.
[0052] Furthermore, since the connector pipe 35 and the
enlarged-diameter part 36 are inclined to each other at a certain
angle, the connector 34 can come into close contact with the lower
vessel 10, the inner face of which is curved. In addition, the
connector 34 does not require much installation space. In this
embodiment, the connector 34 may be positioned in the interspace
between the side of the suction silencer 30 and the inner face of
the lower vessel 10.
[0053] As set forth before, the connector of the hermetic
compressor and the working fluid suction device using the same as
embodied and broadly described herein have the following
effects.
[0054] First, the connector communicating between the suction pipe
and the suction silencer is made of an elastic material and has no
protrusion therein, so that working fluids can flow smoothly.
Particularly, the contact skirt is in close contact with the inner
face of the hermetic vessel, thereby minimizing the leakage of
working fluids. Thus, the working fluids introduced into the
hermetic vessel are prevented from being leaked, and the working
fluids are not affected by the internal space of the hermetic
vessel, thereby increasing the compression efficiency of the
compressor.
[0055] Moreover, the connector is connected between the
communication pipe on the side of the suction silencer and the
suction pipe passing through the hermetic vessel such that it
communicates with the suction pipe in the state where the
communication pipe and connector are installed at the side of the
suction silencer, so that a gap between the suction silencer and
the hermetic vessel can be minimized. Thus, the internal space of
the hermetic vessel can be efficiently utilized, thereby providing
an effect of making the size of the compressor smaller.
[0056] Although certain embodiments are described herein for
illustrative purposes, those skilled in the art will appreciate
that various modifications, additions and substitutions are
possible, without departing from the scope and spirit of the
embodiments as disclosed in the accompanying claims.
[0057] For instance, while the embodiment has illustrated that the
connector pipe 35 is coupled to the communication pipe 33 provided
on one side of the suction silencer 30, the connector 34 may be
directly coupled to one side of the suction silencer 30 so as to
allow the inside and outside of the suction silencer 30 to
communicate with each other.
[0058] Any reference in this specification to "one embodiment," "an
embodiment," "example embodiment," etc., means that a particular
feature, structure, or characteristic described in connection with
the embodiment is included in at least one embodiment of the
invention. The appearances of such phrases in various places in the
specification are not necessarily all referring to the same
embodiment. Further, when a particular feature, structure, or
characteristic is described in connection with any embodiment, it
is submitted that it is within the purview of one skilled in the
art to effect such feature, structure, or characteristic in
connection with other ones of the embodiments.
[0059] Although embodiments have been described with reference to a
number of illustrative embodiments thereof, it should be understood
that numerous other modifications and embodiments can be devised by
those skilled in the art that will fall within the spirit and scope
