Description
1. FIELD OF THE INVENTION
[0001] The invention relates to a refrigerating appliance,
comprising a refrigerating chamber for goods to be refrigerated, a
housing receiving the refrigerating chamber at least partially, at
least one door which is provided on a housing opening of the
housing, can be moved with respect to the housing and provides
access to the refrigerating chamber, and further comprising a door
attachment which is provided between the door and the housing and
includes an opening device having a rocker lever for moving the
door about a tilting axis, particularly a horizontal tilting axis,
from a closed to an open position.
2. DESCRIPTION OF THE PRIOR ART
[0002] In order to make a refrigerating chamber of a refrigerating
appliance accessible which is closed off by a door, doors with a
large variety of door attachments are known which enable the moving
of the door from a closed to an open position via an opening
device. A door attachment is known for example from DE 140 1 078 A1
which movably fastens a door via a tilting device to the housing.
Two rocker levers are provided for this purpose to the side of the
door in order to enable the tilting of the door in a vertically
upward way with one movement of the same. Although such door
attachments are able to provide obstruction-free access to the
refrigerating chamber of the refrigerating appliance, it has been
noticed that tilting devices, in addition to the increased static
preconditions placed on the tilting mechanism, are only suitable
within limits because the thus tilted doors can respond in a
sensitive way to tilting-induced loading forces. Long service
periods which are demanded especially in the case of commercial
usage of refrigerating appliances cannot be ensured by such tilting
mechanisms.
[0003] For this reason, door attachments with alternative opening
devices are known (U.S. Pat. No. 4,369,632) which comprise pivoting
devices with vertically extending pivoting axes. Although such door
attachments offer long service lives in contrast to door
attachments with tilting devices because neither the opening device
nor the doors are subject to comparatively high loads during
opening, it is disadvantageous in such door attachments that when
the doors are opened they protrude outwardly from the refrigerating
appliance and thus limit the area of movement around the
refrigerating appliance. An obstruction-free access cannot be
ensured by these door attachments, leading to disadvantages in
connection with convenience of the same.
SUMMARY OF THE INVENTION
[0004] The invention is therefore based on the object of providing
a refrigerating appliance with a movable door of the kind mentioned
above which can ensure in a simple constructional manner both high
stability of the door attachment and obstruction-free access to the
refrigerating chamber.
[0005] This object is achieved by the invention in such a way that
the door attachment comprises a carrier which is connected to the
rocker lever and in particular adjoins the rocker lever, wherein
said carrier carries at least part of a further opening device of
the door attachment for moving the door from a closed position into
an open position which differs from the open position of the other
opening device.
[0006] If the door attachment comprises a further opening device
for moving the door from the closed position to an open position
which differs from the open position of the other opening device,
it is enabled in accordance with the invention to provide a stable
tilting device in a simple manner, because on average an even use
of both access alternatives will occur depending on the habits of
the users, so that a tilting device can also be provided without
any special additional constructional measures. The service life
can be increased especially when the door attachment comprises a
carrier connected with the rocker lever, which carrier carries at
least a part of a further opening device of the door attachment.
The tilting-induced loads of the door can thus be discharged to the
carrier, which can improve the strength of the door and especially
the stability of the door attachment. Simple constructional
conditions are obtained when the carrier is disposed adjacent to
the rocker lever. In contrast to the state of the art, the
invention can thus not only ensure an increased service life of the
refrigerating appliance but also alternative and also
obstruction-free access among other things to the refrigerating
appliance.
[0007] In particular, the door and/or the further opening device
can be relieved from tilting-induced forces when the door
attachment comprises a support and the carrier is arranged in
relation to the door in such a way that during the movement of the
door about the tilting axis the carrier ensures discharge of the
forces onto the rocker lever via the support. Tilting-induced
deformation forces can thus be discharged in a simple manner, which
thus reduces the constructional preconditions both for the door and
for the further opening device. That is why doors with glass
surfaces or glass doors can be provided to be tiltable as compared
with the state of the art, which can be advantageous especially for
operating comfort because the merchandise of the refrigerating
chamber can be inspected prior to opening the door. An additional
factor is that with the support it is possible to improve the
security of the door attachment by reducing the likelihood of
breakage of the door or door fastening. The carrier can be arranged
in relation to the door in such a way that it provides a connection
of forces during the tilting of the door in addition to the further
opening device in order to thus enable the relief of forces in an
improved manner on the tilted door. The carrier is preferably used
for an at least partial support of the tilted door. It is
understood that the rocker lever need not be regarded at all times
as a straight lever; it could certainly assume a common shape with
the carrier which can have a large variety of progressions.
[0008] If the carrier comprises a carrier frame, it is not only
possible to create a sturdy construction for the further opening
mechanism, but this frame can advantageously also be used as a
sturdy support. Moreover, the frame can relieve the tilted door for
example on all sides, which can enable a comparatively high
security against the damage of doors with glass surfaces or glass
doors. Simple constructional conditions are obtained when the
rocker lever and the carrier form a common component.
[0009] Simple constructional conditions for a sliding guide can be
obtained when the carrier has a horizontal guide of the sliding
guide, because the carrier can thus be used in a constructional
manner for the further opening device arranged as a sliding
guide.
[0010] If the further opening device is arranged as a pivoting
device which comprises a pivot bearing which is fastened to the
carrier and comprises a swivel axis which extends especially in a
normal way and is inclined in relation to the tilting axis, a
cost-effective suspension for the door can be created independent
of the door construction.
[0011] In order to enable the prevention of any uncontrolled
pivoting of the tilted door it can be provided that the carrier
provided on the door side facing the refrigerating chamber delimits
the swivel range of the door. The security of the door attachment
can thus be improved in a simple way because when the door is
tilted it will rest on the carrier in a manner limited by the stop
and is thus unable to perform any undesirable pivoting movements
during the tilting of the door.
[0012] In order to increase the torsional rigidity of the housing
against tilting loads, a force-connecting support strut can be
provided between the housing wall protruding from the housing cover
and the housing cover.
[0013] If the housing comprising a support frame delimits at least
partly a recirculating air circuit which supplies the temperature
to the refrigerating chamber between the frame carriers and the
carrier connections, the dimensions of the refrigerating appliance
can advantageously be kept small because the guide devices to be
provided for the recirculating air can be housed between the
refrigerating chamber and the outside of the housing or the housing
can be used for forming this device. Advantageous visible
conditions can be provided when the recirculating air circuit
comprises openings for supplying cooling air to the door facing the
refrigerating chamber at least in the connecting region of housing
and door because condensation water on the door can thus be
prevented in a simple way.
[0014] Depending on the force load to be discharged, two rocker
levers can be provided for the tilting device, which rocker levers
are spaced from one another, extend especially in a parallel way,
act jointly on the support frame and are each fastened via a pivot
bearing to the cover of the housing. Moreover, the constructional
dimensions of the refrigerating appliance can be reduced in that
means such as a compressor and/or condenser are provided in the
intermediate area of the two rocker levers for the refrigerant
circuit of the recirculating air circuit.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0030] A refrigerating appliance shown by way of example in FIG. 1
comprises a refrigerating chamber 1 for the storage of goods to be
refrigerated which are not shown in closer detail. The
refrigerating chamber 1 is partly enclosed by a housing 2. A door 4
with two wings 5 and 6 is provided in a housing opening 3 of
housing 2, with the door 4 being connected with the housing 2 via a
door attachment 7. The door attachment 7 enables the movement of
the doors in order to thus reach the goods of refrigerating chamber
1. Such a door movement is first enabled with the help of an
opening device 8. This opening device 8 provides a possibility for
movement of the door 4 about a horizontal tilting axis 9 from a
closed position 10 to an open position 11, with the two positions
10 and 11 being shown in FIG. 2. Although the open position 11
shown with the dot-dash line in FIG. 2 represents an end position,
other tilted open positions are possible, but are not shown for
reasons of clarity of the illustration. This open position 11 is
characterized in that the door 4 does not protrude into the space
of movement of the user in front of the refrigerating appliance.
The door 4 is disposed substantially above the housing cover 12 of
housing 2. Since the door 4 comprises transparent areas 13 and is
thus partly transparent, the goods stored in the refrigerating
chamber 1 can be seen from the outside. The door 4 can be arranged
in a predominantly or mainly transparent or even opaque way. It is
a disadvantage in the removal of refrigerated goods that a
comparatively wide opening of the refrigerating appliance is
necessary tilting the door 4 in order to remove the goods from the
refrigerating chamber 1. In order to ensure that an improved
retrieval can be created which is better adjusted to the position
of the refrigerated goods in the refrigerating chamber 1 it is
proposed in accordance with the invention that the door attachment
7 comprises a carrier 15 which is adjacent to the rocker lever 14
of the opening device 8 and which carries at least parts 16 of a
further opening device of the door attachment 7 arranged as a
swivel device 17 for moving the door 4 from the closed position 10
to an open position 18 which is different from the open position 11
of the tilting device 8. The open position 18 is shown especially
in FIG. 3. The operating convenience of the refrigerating appliance
is thus increased because the swivel device 17 creates a second
possibility for movement of the door 4 or the door wings 5 and 6
about a substantially vertically extending swivel axis 19.
[0031] The door attachment 7 is shown in closer detail in FIGS. 4
and 5. The welded carrier 15 is adjacent to the tilting device 8
and adjacent thereto is the pivoting device 17. The opening device
8 is formed by a tilting bearing 20 and a rocker lever 14, which
rocker lever 14 can be moved about the horizontal tilting axis 9 of
the tilting bearing 20. The carrier 15 protrudes vertically from
the rocker lever 14 in order to allow support means 21, e.g. a
tension-compression spring, to act on said carrier 15 in order to
facilitate the tilting movement. The pivoting device 17 is fastened
to the carrier 15, with the part 16 of the pivoting device 17
enclosing the carrier 15 and protruding from the carrier 15, so
that the pin 19' forming a vertically extending swivel axis 19 can
engage in the other parts of the pivoting device 17, which other
parts are fastened to the door 4 (not shown). The carrier 15 can be
encompassed in the region of the housing opening 3 with insulation
(not shown in closer detail) in order to thus reduce the thermal
conductivity of the carrier 15.
[0032] The carrier 15 forms a carrier frame 15' which extends
parallel to the side edges of door 4, which is shown in more detail
in FIG. 5. In order to relieve the door and the further opening
device, carrier 15 is arranged in relation to the door 4 in such a
way that when door 4 is moved about the tilting axis 9 the carrier
frame 15' of the carrier 15 is used as a support 22 for an at least
partial support of the tilted door 4. This is also especially shown
in FIG. 2. The carrier frame 15' which is arranged behind the door
4 is swiveled with the door 4 and is able to relieve the door at
least on the edge with its support 22. The relief on the edge side
can also be provided on the upper side and/or bottom side of the
door. It is also possible that the sides of the door are relieved,
which can be the case for example when the door is deflected.
Carrier 15 can thus ensure an especially good discharge of forces
onto the rocker lever 14, thus providing a stable and secure door
attachment 7. The rocker lever 14 advantageously forms a common
component with the carrier 15. It is also possible to arrange the
carrier 15 and the rocker lever 14 in an integral way.
[0033] The security in the operation of the refrigerating appliance
can especially be improved when the carrier 15 provided to the side
of the door facing the refrigerating chamber 1 delimits the
swiveling range of door 4 with its support 22, which is shown in
particular in FIGS. 2 and 3. The support 22 is arranged on the
carrier frame 15' in relation to the door in such a way that no
additional vertical displacement or swiveling movement of the door
4 or the door wings 5 and 6 can occur during a tilting movement of
the door 4. It is possible that additional means are provided
between the carrier 15 and the door 4 in order to thus provide a
support 22, which does not change anything in the respect that the
carrier 15 is used for the support 22. During a tilting movement of
the door 4, the door 4 on the carrier 15 additionally discharges
load to the further opening device.
[0034] A force-connecting support strut 24 is provided between
housing cover 12 and the rear wall 23 of the housing which
protrudes beyond the housing cover 12.
[0035] The tilting device 7 further comprises two mutually spaced
and parallel extending rocker levers 14, in the intermediate area
of which there are means 25 for the refrigerant circuit of the
refrigerating appliance. This can represent a compressor for
example in order to avoid having to provide the same on the floor
of the refrigerant appliance, which enables a low loading edge of
the refrigerating appliance. It need not be mentioned further that
differently extending rocker levers 14 are possible.
[0036] The overall size of the refrigerating appliance can be
reduced when the housing 2 which comprises a carrier frame at least
partly delimits a recirculating air circuit 26 between its frame
supports 2' and transverse connections 2'', which air circuit
subjects the refrigerating chamber 26 to refrigerating and is shown
in close detail in FIG. 6. In order to reduce the formation of
condensation water, the recirculating air circuit 26 comprises an
outlet 27 with nozzles 28 for supplying refrigerating air to the
door side facing the refrigerating chamber in the region of the
housing opening 3 adjacent to the door 4. In order to provide a
forced circuit of refrigerating air, the outlet 27 is arranged on
the housing cover 12, with a fan 30 arranged in the floor 29 of the
housing introducing via an inlet 31 the air ejected from the outlet
27 into the recirculating air circuit 26. Furthermore, the
evaporator 33 of the recirculating air circuit for refrigerating
the refrigerating air guided in the recirculating air circuit 26 is
housed in the rear wall 32 of the housing. Furthermore, nozzles 28
are provided in the rear wall 32 through the transverse connections
2'', so that the goods which are stored in the shelves 34 and are
not shown here can be subjected to refrigerating air. Furthermore,
the refrigerating appliance comprises handles 35 for actuating the
door wings 5 and 6. A thermal insulation 36 is advantageously
applied to the outside of the housing.
[0037] FIG. 7 shows an alternative embodiment of an opening device
8'. In contrast to the opening device 8 shown in FIG. 4, this
opening device 8' comprises a two-arm rocker lever 14' which is
fastened to the transverse strut 24' via a tilting bearing 20'.
Support means 21' such as a tension-compression spring act via the
lever extension 14'' of the rocker lever 14' for the purpose of
facilitating the tilting movement of the door 4. The support means
21' are movably held on the housing 2. The support frame 15'
arranged behind the door 4 is swiveled together with the door 4 and
can relieve the door with its support 22. The carrier 15 thus
enables an especially good discharge of forces on the rocker lever
14'. In particular, the stiffness in the cover area 12 of the
refrigerating appliance can be improved with a transverse strut 24'
which acts substantially on the outer edge of the housing cover 12
and on the protruding rear wall 23 of the housing.
[0038] FIG. 8 shows a further embodiment concerning the opening
device 8. In comparison with the embodiment according to FIG. 2,
this opening device 8' comprises a two-arm rocker lever 14',
similar to FIG. 7. In contrast to the tension-compression spring as
shown in FIG. 2, this embodiment comprises support means 21' which
contribute to facilitating the tilting of door 4 with the help of a
traction cable 38 which is guided via a deflection roller 37 and is
tensioned with a tension means 39. Pulling weights, motors or also
a tension-compression spring can be used as tensioning devices.
[0039] Moreover, the further opening device can be arranged as a
sliding guide 40, which is shown as a further embodiment according
to FIGS. 9 and 10. The carrier 15 advantageously comprises a
horizontal guide 41 of the sliding guide 40, which reduces the
constructional complexity. The two door wings 5 and 6 run on
rollers 42 in the guide 41 next to one another, so that the
refrigerating chamber 1 is accessible by a displacement of the door
wing 5 or 6. An abridged view is shown according to FIGS. 9 and 10.
It is understood however that that the same guide cannot
necessarily be provided at the bottom end of the door. The carrier
15 also forms a support 22 in addition to the guide 41, which
support rests on the upper side surfaces of the door 4 or the door
wings 5 and 6, which can be recognized in FIG. 10. Furthermore, the
carrier 15 also comprises a carrier frame 15', into which the door
wings 5 and 6 can each protrude. This is not only advantageous
concerning thermal insulation, but the carrier frame 15' can also
act in this case as a support 22, because the side surfaces of the
door 4 or the adjacent sides of the door wings 5 and 6 can rest
there when a tilting of the door occurs.
[0040] A further embodiment is shown in FIGS. 11 and 12, with the
further opening device being arranged in this case as a pivoting
device 17'. In contrast to the pivoting device 17 of FIG. 4, the
rocker lever 14 is connected with the carrier 43 via the pivoting
device 17'. The rocker lever 14 thus carries a part 16 of the
pivoting device 17' of the door attachment 7 for moving the door 4,
with the part 16' protruding from the carrier 43 in order to enable
engaging into the other parts of the pivoting device 17' with a pin
19' forming a vertically extending pivoting axis 19, which other
parts are provided on the carrier 43. The carrier 43 is fastened to
the door 4 via several connection means 44 in order to thus
discharge tilting-induced deformation forces from the door 4 in a
simple way, which is especially advantageous in the case of doors
with glass surfaces or glass doors. The carrier 43 is provided
between rocker lever 14 and door 4, which can be utilized
advantageously for supporting the tilted door. The carrier 43 is
arranged in relation to the door 4 in such a way that during the
movement of door 4 about the tilting axis 9 the carrier 43 is
movable in the direction of the rocker lever 14, so that the
carrier 43 is used as a support 22 for supporting the tilted door
4. In this case, the support 22 is provided between carrier 43 and
rocker lever 14 and not, as shown in FIG. 2, between carrier 15 and
door 4. FIG. 11 shows a considerable distance between carrier 43
and the rocker lever 14. The width of the distance is determined by
the possibility of the mobility of the carrier 43 in the direction
of the rocker lever 14. It is possible for example to overcome this
distance by tolerated deformation forces in order to thus obtain a
support 22.
[0041] A further embodiment is shown according to FIGS. 13 and 14.
In contrast to the embodiment according to FIGS. 11 and 12, the
carrier 43' is a part of the door 4, which carrier 43' carries the
glass surface 13 and parts of the pivoting device 17'. In this case
too, the rocker lever 14 can be used as a support 22 for the
carrier 43' when it is moved during the tilting of the door 4 in
the direction of the rocker lever 14. The carrier 43' is arranged
in such a way that pivoting of the door 4 which is unobstructed by
the rocker lever 14 is possible.
[0042] It is also generally possible to use means between carrier
and rocker lever or door before tilting the door, which means
contribute to the formation of the support instead of a movement of
the carrier or door.
