Description
BACKGROUND OF THE INVENTION
[0001] The invention relates to a housing, preferably a
hermetically sealing housing, a small-type refrigerating machine
for receiving an electromotor and a piston-cylinder unit driven by
the same for compressing a refrigerant guided via feed lines and
discharge lines into the housing and into the piston of the
piston-cylinder unit, with the housing being provided with at least
one connecting element for fastening to a support plate, in
accordance with the preamble of claim 1.
DESCRIPTION OF THE PRIOR ART
[0002] Housings for this type of small-type refrigerating machines
are well known. Such a housing is mounted during installation on a
base plate arranged on the refrigerating machine. For mounting on
the base plate, a connecting element is usually used which enables
the fastening of the housing to the base plate.
[0003] Connecting elements consist of two fastening brackets for
example, with the maker of the small-type refrigerating machine
ensuring the mounting ability of the housing on a support plate or
base plate of the refrigerating machine by providing a suitable
configuration of the support element. Such a standardization
concerning the fastening brackets relates especially to their outer
distances and to the distances of the holes and hole diameters for
receiving the fastening means such as screws. Four holes are
usually provided for receiving the fastening means which have a
distance of 170.times.70 mm from each other. With the help of the
fastening brackets the small-type refrigerating machine is fastened
to the support plate of the refrigerating machine. The fastening
brackets of the small-type refrigerating machines are usually
welded onto the housing.
[0004] Support plates are usually not separately produced for
small-type refrigerating machines of smaller dimensions, but also
for small-type refrigerating machines of larger configurations. The
support plates thus usually have dimensions which are much larger
than actually necessary for securely fastening the small-type
refrigerating machines. This represents an unnecessary additional
expenditure of required material since one needs to consider that
small-type refrigerating machines of this kind are made in high
numbers and said additional expenditure of material can therefore
be considerable. Moreover, a large number of mounting parts is
necessary which cause additional mounting work and costs.
[0005] Furthermore, there are sometimes difficulties in the
operation of small-type refrigerating machines as a result of the
occurring vibrations of the housing. Vibrations promote material
fatigue and increased noise and reduce the bearing strength of the
housing on the support plate. Although it is tried in accordance
with the state of the art to prevent the transmission of vibrations
onto the support plate with the help of vibration-damping elements
in the holes for the fastening means, this measure however
increases mounting work and the number of required components.
Moreover, the currently used connecting elements have proven to be
unfavorable concerning a reduction of the vibration transmission
from housing to support plate and a reduction of the vibrations of
the housing itself.
[0006] A fastening apparatus for hermetic compressors is known from
WO 00/46504, with connecting elements being provided which can be
coupled with deep-drawn parts arranged on the floor side of the
housing. The connecting elements comprise flanged sections which
are provided with bores and with which the connecting elements plus
housing are mounted on a support plate.
[0007] A compressor housing is known from U.S. Pat. No. 4,964,786
which is fastened to a support plate by means of a cup-shaped
connecting element. The connecting element is integrally made of
elastic material and pressed with a web-shaped wall into a
ring-shaped groove on the floor of the compressor housing where it
is fastened additionally with a layer of adhesive. The planar,
disk-like floor of the connecting element is subsequently also
fastened by a layer of adhesive on the base plate.
[0008] It is the goal of the present invention to avoid the
mentioned disadvantages and to ensure producing a connection
between the housing and the support plate by means of a suitable
configuration of the housing and the connecting element fastened to
the same which reduces the need for material and the amount of
mounting work and the number of components required for this
purpose and thereby reducing the costs, and also allowing a
technically simple reduction of the transmission of vibrations from
the housing to the support plate and reduction of the vibrations of
the housing. These objects are achieved by the characterizing
features of claim 1.
SUMMARY OF THE INVENTION
[0009] Claim 1 relates to a housing, preferably a hermetically
sealing housing, a small-type refrigerating machine for receiving
an electromotor and a piston-cylinder unit driven by the same for
compressing a refrigerant guided via feed lines and discharge lines
into the housing and into the piston of the piston-cylinder unit,
with the housing being provided with at least one connecting
element for fastening to a support plate. It is provided in
accordance with the invention that in a direction of view
perpendicular to the support plate the outermost dimensions of the
housing protrude beyond the outermost dimensions of the at least
one connecting element, and the connecting element or the imaginary
shortest connecting line along the surface of the housing between
the connecting elements in the case of several connecting elements
encloses a surface area of the housing facing the support plate.
The volume which is enclosed by the at least one connecting element
and which receives the surface area of the housing facing the
support plate is delimited by the support plate on its side
opposite of the housing, which means that the surface area of the
housing enclosed by the at least one connecting element faces
directly to the support plate. The connecting element of a housing
in accordance with the invention is provided with a considerably
smaller configuration than the one according to the state of the
art. Since also at least one connecting element or its imaginary
connecting line encloses a surface area of the housing facing the
support plate, it is also possible to follow an antinode line on
the housing in the arrangement of the at least one connecting
element in order to achieve advantageous vibration-damping effects,
as will be explained below in closer detail.
[0010] Claim 2 provides that in a direction of view oriented
parallel to the support plate, the at least one connecting element
protrudes beyond the surface section of the housing which faces and
is enclosed by the support plate. This enables simpler fastening of
the at least one connecting element to the support plate and also
ensures that after mounting the housing does not touch the support
plate. As a result, vibrations from the housing are carried off
only via the connecting element.
[0011] Claim 3 relates to a first embodiment, according to which
precisely one connecting element is provided which is arranged as a
support body in the shape of a cylinder or truncated cone and with
a base surface in the shape of an annulus which encloses the
surface area of the housing facing the support plate.
[0012] Claim 4 relates to a further embodiment, according to which
precisely one connecting element is provided which is arranged as a
cuboid support frame which encloses the surface area of the housing
facing the support plate.
[0013] Claim 5 describes for both these embodiments a possibility
for fastening the connecting element to the housing. In accordance
with claim 5, the at least one connecting element comprises at
least one chamber with an opening facing the housing for receiving
a holding element protruding from the housing.
[0014] A solution in analogy to claim 5 can also be used for
fastening the connecting element on the support plate, as is
proposed in claim 6. In accordance with claim 6, the at least one
connecting element comprises at least one chamber with an opening
facing the support plate for receiving a holding element protruding
from the support plate.
[0015] One embodiment for the interaction between holding element
and chamber as mentioned in claim 5 and 6 is proposed in claim 7,
according to which the opening of the at least one chamber forms a
holding shoulder and the holding element comprises an undercut for
latching into the holding shoulder.
[0016] A further possibility for fastening the connecting element
to the support plate is proposed in claim 8, according to which the
at least one connecting element comprises a laterally arranged slit
for receiving the free end of a holding bracket protruding from the
support plate.
[0017] The arrangement of the housing in accordance with the
invention also allows an alternative variant in accordance with
claim 9, according to which at least three connecting elements are
provided which are arranged as support feet protruding axially from
the housing, with the imaginary shortest connecting line between
the support feet along the surface of the housing enclosing the
surface area of the housing facing the support plate. At least
three connecting elements are advantageous for the reason that a
stable bearing of the housing on the connecting elements can be
ensured with at least three connecting elements. The surface
section of the housing facing the support plate can have the
approximate shape of a spherical cap. According to claim 10, two of
the support feet can be arranged in the manner of pegs with a
support plate each which can each be inserted into a breakthrough
in the support plate, and the third support foot can be provided
with a tab-like configuration which can be inserted into a further
breakthrough in the support plate.
[0018] As a result of these different embodiments in accordance
with the invention, an especially simple reduction of vibrations of
the housing and their transmission from housing to support plate is
achieved, such that in accordance with claim 11 the at least one
connecting element is made at least partly of an elastomeric
material or according to claim 12 the contact surface of the at
least one connecting element with the housing is arranged in the
region of antinodes of the overall system consisting of housing and
connecting body, which antinodes correspond to usual operating
states.
[0019] In accordance with claim 13, the at least one connecting
element can be formed on the housing.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0038] FIG. 1 shows a view of a housing 1 for a small-type
refrigerating machine with connecting elements in the form of two
fastening brackets 3 according to the state of the art (FIG. 1 only
shows one of the fastening brackets 3). The fastening brackets 3
are fastened to flange-like noses 4 of housing 1 by means of a
welded connection for example, as is shown especially in FIG. 2.
Two vibration-damping support elements 2 are arranged on the two
fastening brackets 3, which support elements are finally fastened
to the support plate or base plate of the refrigerating machine.
The support plate is now shown in FIGS. 1 and 2. It is clearly
visible that several components are necessary for mounting the
small-type refrigerating machine on the support plate or base plate
of the refrigerating machine, thus leading to additional mounting
work, need for material and mounting time. It can further be seen
that the vibration damping of the oscillating housing 1 on the
support or base plate of the refrigerating machine is not
satisfactory, which promotes material fatigue and additional noise
development. These disadvantages are to be avoided by an optimal
mounting solution.
[0039] FIGS. 3 to 5 show an embodiment of making an improved
connection between housing 1 and a support plate 5 which
subsequently is fastened to the base plate of the refrigerating
machine. The connection is made with the help of a connecting
element which is arranged in this embodiment as a cylindrical
support body 6 with an annular base. The support body 6 is fastened
to the surface of housing 1 facing the support plate 5 and encloses
a surface section of housing 1 facing the support plate. As is
shown especially in FIG. 5, the height of the cylindrical support
body 6 is chosen in such a way that the lowermost point P of the
housing 1 is slightly spaced from the support plate 4,
approximately 1 to 5 mm. An elastomeric material is preferably used
for the support body 6 which has vibration-damping properties. The
type of fastening of the support body 6 to housing 1 and the
support plate 5 will be explained below in closer detail. FIGS. 3
to 5 show especially that the outermost dimensions of the housing 1
protrude beyond the outermost dimensions of the support body 6 in a
direction of view oriented perpendicularly to the support plate 5.
The support body 6 can therefore be provided with a comparatively
small configuration. The volume which is enclosed by the support
body 6 and which receives the surface area of housing 1 facing the
support plate 5 is delimited by the support plate 5 on its side
opposite of housing 1, so that the surface area of housing 1
enclosed by the support body 6 faces directly towards the support
plate 5. The overall height of the support body 6 is thus kept
low.
[0040] Moreover, the positioning of the support body 6 is
advantageously chosen in such a way that it is arranged on housing
1 in the region of antinodes of the overall system consisting of
housing 1 and connecting body 6, which antinodes correspond to
usual operating states.
[0041] As an alternative to this, the support body 6 could also be
arranged in the shape of a truncated cone and with an annular base
surface. It is further possible that the support body 6 is not
provided with an integral configuration, but is composed of
mutually spaced annular segments which are arranged along a
circumferential line of one of the surface sections of housing 1
facing the support plate 5. In this case, an imaginary, very short
connecting line can be drawn along the surface of housing 1 between
the individual segments which enclose a surface area of housing 1
facing the support plate 5. Such an embodiment would lead to
additional material savings concerning the support body 6.
[0042] A further embodiment for a connecting element in accordance
with the invention is shown in FIGS. 6 to 8. As has already been
indicated above, the connecting element is provided with multi-part
configuration, namely in the form of three support feet 7, 8, 9
which protrude axially from the housing 1 and which are
subsequently fastened to a support plate 10. The support feet 7, 8,
9 are situated within the outermost dimensions of the housing 1 in
a direction of view oriented perpendicularly to the bearing plate
10, with the imaginary shortest connecting line between the support
feet 7, 8, 9 along the surface of the housing 1 enclosing a surface
area of housing 1 facing the support plate 10 (see FIG. 8). The
arrangement of said support feet can vary. In FIGS. 6 to 8 it is
proposed that two of said support feet 8, 9 are provided with a
peg-like configuration and are provided with a preferably square
support plate 11 which can be inserted into a respective
breakthrough 12 of the support plate 10. The third support foot 7
is provided with a tab-like configuration and engages in a further
breakthrough 13 of the support plate 10. In the course of mounting
housing 1 on support plate 10, the square support plates 11 are
inserted into the breakthroughs 12 and tightly clamped with the
help of the support foot 7 engaging in the breakthrough 13. The
support feet 7, 8, 9 can be formed or welded onto housing 1. The
support feet 7, 8, 9 can comprise sections for vibration damping
which are made of an elastic material. As is shown especially in
FIG. 7, the height of the support feet 7, 8, 9 is chosen in such a
way that the lowest point P of housing 1 is slightly spaced from
the support plate 10 in the mounted state, e.g. 1 to 5 mm.
[0043] FIGS. 9 to 11 show a further embodiment of an improved
connection between housing 1 and a support plate 14, which
subsequently will be fastened to the base plate of the
refrigerating machine. The connection is made by means of a
connection element which in this embodiment is arranged as a cuboid
support frame 15. The support frame 15 is fastened to the surface
of housing 1 facing the support plate 14 and encloses a surface
section of housing 1 facing the support plate 14. As is shown
especially in FIG. 11, the height of the support frame 15 is chosen
in such a way that the lowermost point P of housing 1 is slightly
spaced from the support plate 14, approximately 1 to 5 mm. An
elastomer is preferably used for the support frame 15, which
elastomer has vibration-damping properties. FIGS. 9 to 11 also show
that in a direction of view perpendicular to the support plate 14
the outermost dimensions of the housing 1 protrude beyond the
support frame 15, as a result of which the support frame 15 can be
provided with a comparatively small configuration. Moreover, the
positioning of the support frame 15 is advantageously chosen in
such a way that it is arranged on the housing 1 in the region of
antinodes of the entire system which consists of housing 1 and
support frame 15, which antinodes correspond to the usual operating
states.
[0044] It is also possible that the support frame 15 is not
provided with an integral configuration but is composed of mutually
spaced cuboid segments. In this case, an imaginary shortest
connecting line can be drawn along the surface of the housing 1
between the individual segments which encloses a surface area of
the housing 1 facing the support plate 14. Such a configuration
would lead to additional savings in material concerning the support
frame 15.
[0045] The type of fastening of the support frame 15 to housing 1
and to support plate 14 can be made in such a way that two tabs 16
are punched out of the support plate 14 and are bent up
perpendicular to the support plate 14, the free end section 17 of
which is then bent horizontal to the support plate 14 (see FIG. 10;
merely one of the two tabs 16 is shown). Two holding brackets 27
are thus formed. The two tabs 16 extend parallel with respect to
each other and correspond in respect of their distance to an outer
dimension of the support frame 15. The support frame 15 can
therefore be inserted between the two tabs 16. It comprises lateral
slits 18 in which the horizontal end sections 17 of the tabs 16
engage. The housing 1 is thus already fixed in two spatial
directions. In order to fix the housing 1 in the spatial direction
parallel to the tabs 16, a further tab 19 can be punched from the
support plate 14 and can be bent up perpendicular to the support
plate 14 which is oriented perpendicular to the tab 16 and rest
tightly on the support frame 15 in the bent-up position. The
housing 1 can thus be mounted in a simple and cost-effective manner
on support plate 14.
[0046] A similar procedure can also be chosen with such embodiments
in which the connecting element is arranged as a cylindrical
support body 6 according to FIGS. 3 to 5. This will be explained
below by reference to FIGS. 12 to 15.
[0047] The type of fastening of the support body 6 to housing 1 and
the support plate 5 can occur in an analogous manner in such a way
that two tabs 20 are punched out of the support plate 5 and are
bent up perpendicular to the support plate 5, the free end section
21 of which is then bent horizontally to the support plate 5 (see
FIG. 12 and FIG. 13). Two holding brackets 28 are thus formed. The
two holding brackets 28 are arranged in such a way that they can
come into engagement with the lateral slits 22 of the support body
6. The support body 6 can therefore be pushed in the direction of
the two holding brackets 28, with the horizontal end sections 21 of
the holding brackets 28 engaging in the slits 22. In order to
further fix the housing 1 to support plate 5, a further tab 23 can
be punched out of the support plate 5 and can be bent up
perpendicular to the support plate 5 which in the bent-up position
rests snugly on support body 6. Said tab 23 is positioned relative
to the holding brackets 28 in such a way that a movement of the
support body 6 relative to the holding brackets 28 is suppressed.
Housing 1 can thus be mounted in a very simple and cost-effective
manner on the support plate 5.
[0048] FIGS. 16 and 17 explain a further possibility of fastening
the housing 1 or the connecting element 6 to the support plate 5.
As is shown especially in FIG. 17, the support body 6 comprises a
chamber 24 with an opening facing the support plate 5. The support
plate 5 is provided on its part with a holding element 25 which is
received by chamber 24. Preferably, the opening of chamber 24 forms
a holding shoulder, so that an undercut 26 of the holding element
25 can latch into the chamber 24.
[0049] One possibility for mounting the support body 6 or the
support frame 15 on housing 1 is shown in FIG. 13. The support body
6 or the support frame 15 comprises a chamber 29 with an opening
facing the housing 1. Housing 1 is provided on its part with a
holding element 30 which protrudes in the axial direction and is
received by chamber 29. Preferably, the opening of chamber 29 forms
a holding shoulder, so that an undercut 31 of the holding element
30 can latch into the chamber 29. The holding element 30 can be
formed on the housing 1 or welded onto the same.
[0050] The embodiment of the housing or the connecting element
fastened to the same in accordance with the invention enables
producing a connection between the housing and the support plate
which reduces the amount of material and mounting work and the
number of components required for this purpose, thus reducing the
costs and also enabling a technically simple reduction of the
transmission of vibrations from the housing to the support plate
and a reduction of the vibrations of the housing.
