[0001] The invention relates to a door having a sandwiched construction formed by an outer
shell, an inner shell and a frame interleaved therebetween, wherein the door has a
hinge for pivotable or pivotably mounting the door to a body of a laundry machine,
in particular to a washing machine, a dryer or a wash dryer.
[0002] EP 2 147 996 A1 discloses a door for a dryer, the door being formed of a sandwiched construction
having an outer cover, an inner cover and sandwiched therebetween a ring-shaped frame.
The frame provides mechanical stability for the thin walls of the outer and inner
cover. The inner frame and the outer cover can be selectively be mounted in a 180
degree turn arrangement so that the door can be pivotable mounted to the body of the
dryer at the left or right side of the loading opening. The hinge is formed by a body-side
hinge part to be mounted at a frame of the loading opening, and a door-side hinge
part, wherein the body-side hinge part and the door-side hinge part are pivotable
connected together by a common pivot pin. The body-side hinge part has two cantilevers
arranged spaced at a plate of the body-side hinge part. Each cantilever has a bearing
for the pin at the free standing end of the cantilever. The door-side hinge part comprises
two pivot members for receiving the pin which are integrally formed at the periphery
of the ring-shaped frame.
[0003] A double-pivoted door hinge for a washing machine is known from
US 2004/0107741A1, in which the door-side pivoting axis for a swing arm is provided at the inner side
of an outer shell of the door. The door is sandwiched by an outer ring shell and an
inner ring shell, wherein the section at the door-side hinge of the inner ring is
formed by a separate ring section facilitating maintenance and mounting of the door
hinge construction.
[0004] It is an object of the invention to provide a door having a door hinge with improved
mechanical stability; and to provide a laundry machine having such a door.
[0005] The invention is defined in claims 1 and 15, respectively. Particular embodiments
are set out in the dependent claims.
[0006] Claim 1 provides a door for a laundry machine comprising:
an outer cover of the door,
an inner cover of the door,
a frame element arranged between the outer and inner cover and adapted to support
the outer and inner cover, and
a hinge adapted to pivotable support the door on a laundry machine,
wherein the hinge comprises:
a body-side bearing element adapted to be mounted or mounted at a body of a laundry
machine,
at least one door-side bearing element, and
at least one pivot element pivotable connecting the body-side bearing element and
the at least one door-side bearing element ;
wherein
a hinge reinforcement element mounted on the frame element and comprising at least
one of said door-side bearing elements.
[0007] Claim 1 provides a door for a laundry machine, which is formed in sandwiched construction
wherein a frame element is sandwiched between an outer cover and an inner cover of
the door. The door comprises a hinge for pivotable (i.e. pivotably) supporting the
door on a laundry machine, in particular on a frame at a laundry loading opening of
the laundry machine. The hinge comprises a body-side bearing element, at least one
door-side bearing element and at least one pivot element which pivotable connect the
body-side bearing element and the at least one door-side bearing element. The body-side
bearing element is adapted to be mounted at a body of a laundry machine or mounted
at a body of a laundry machine. Preferably the body-side bearing element is an individual
element that can be mounted and released (for example for service) from the body of
a laundry machine. Alternatively the body-side bearing element is an element mounted
at the body of a laundry machine and protruding therefrom such that the hinge connection
between the body and the door is established when mounting the door at the body of
a laundry machine. Preferably the hinge (and thus the hinge connection to the laundry
machine) is a single-axis hinge having only one pivoting axis.
[0008] According to the invention, a hinge reinforcement element is provided as a separate
or individual element which is mounted on the frame element and which comprises at
least one of said door-side bearing elements. By providing the hinge reinforcement
element as a separate or individual element (before mounting it on the frame element),
the manufacturing design and mechanical design of the hinge reinforcement element
can be optimized for pivoting and mechanical purposes, independent of the manufacturing
and mechanical design of the outer cover, the inner cover and the frame element. For
example different and independent material selection can be made for the hinge reinforcement
element as compared to the outer and inner covers and the frame element. Further,
the manufacturing processes can be optimized for the hinge reinforcement element,
independent of that relating to the outer cover, inner cover and frame element. For
example mounting costs can be reduced when the molding or casting tools for the outer
cover, the inner cover and the frame element are only two molding elements that are
applied perpendicular to the plane of the elements to be molded. In contrast thereto,
the pivot hole formed through the door-side bearing element(s) runs in a plane parallel
to a plane of the outer cover, inner cover or frame element. Thus the pivot hole requires
an additional molding or casting tool that is applied in a plane parallel to the main
plane such that an additional and costly mounting tool would be required.
[0009] As a further advantage, the small sized hinge reinforcement element can be manufactured
from a higher value material as compared to the materials of the outer cover, inner
cover or frame element. Small sized relates here to the smaller dimensions of the
hinge reinforcement element as compared to the dimensions of the outer cover, inner
cover and frame element, which is a factor of about 5 or 10.
[0010] According to a preferred embodiment, the frame element is made of a first material
and said hinge reinforcement element is made of a second material, wherein the second
material and the first material are different. In particular the second material is
a material that is mechanically more stable than the first material. "Mechanically
more stable" in this context means that the hinge reinforcement element is made of
the second material having for example a higher carrying capacity and/or rupture strength
as compared to the respective values of the first material. In a preferred embodiment
the first material is plastic, in particular (injection) molded plastic, while the
second material is a metal, in particular iron, steel or galvanized iron.
[0011] Preferably the hinge reinforcement element comprises at least one door-side bearing
element as a single-piece or monolithic component.
[0012] According to a preferred embodiment, the hinge reinforcement element comprises at
least one arm extending or protruding from the hinge reinforcement element and each
of said arms comprises at its free standing end region one of said door-side bearing
elements. In this way the pivoting point and the mounting point of the hinge reinforcement
element are spatially separated such that the location of mechanically coupling the
hinge reinforcement element to the frame element is remote to the pivoting point.
Hence the mechanical load is distributed over a wider area of the frame element. In
particular when in addition to the hinge reinforcement element the frame element comprises
or is provided with at least one door-side bearing element, the locations of transmitting
the mechanical load from the hinge to the frame element is distributed over a wider
area of the frame element.
[0013] In an embodiment, when the hinge reinforcement element has two arms and is forming
a U- or C-shape by the two arms and the connection therebetween, the axially spaced
door-side bearing elements at the arms provide high torsional moment resistance for
the hinge and at the same time distributes the load force over the distributed form
of the U- or C-shape to remote locations where the hinge reinforcement element is
coupled to the frame element.
[0014] According to an embodiment, the frame element comprises an outer frame member forming
the periphery of the frame element, wherein in the section (in particular in the angular
or arc section) of the frame member where the hinge reinforcement element is mounted
to the outer frame member, the extension of the outer frame member towards the center
of the frame element is greater than in the remaining (angular or arc) section where
the hinge reinforcement element is not mounted to the outer frame member. The other
way round it can be said that the radial distance between the center of the frame
element and the inner periphery of the outer frame member is shorter in the angular
section where the hinge reinforcement element is mounted or is to be mounted as compared
to the radial distance to the inner periphery of the outer frame member in those (angular
or arc) sections where the hinge connection is not mounted. This provides the advantage
that the mechanically strength of the frame element is at least the same in the section
or is even increased in the section of the hinge for mounting the hinge reinforcement
element (hinge mounting base). This particularly applies when the outer frame member
comprises a recess or cut-out in the section of the hinge connection such as to provide
a clearance for pivoting the body-side bearing element (the arms thereof) through
the cut-out or recess in the outer frame member.
[0015] Preferably at least a portion of the hinge reinforcement element overlaps and/or
is mounted to the (inner) region of the outer frame member which is extending inwardly
in the section of the hinge connection.
[0016] Preferably the hinge reinforcement element comprises a base plate or a base block
for fixing the hinge reinforcement element to the frame element, wherein the base
plate or base block is mounted adjacent a region of the frame element that is recessed
with respect to the outer periphery of the frame element (recess or cut-out as mentioned
before). In this embodiment at least one arm or cantilever is extending outward from
the base plate or base block towards the periphery of the frame element (when the
hinge reinforcement element is fixed to the frame element). The arm or cantilever
has a pivot receiving member (e.g. door side bearing element) at its freestanding
end for receiving the pivot or pin of the hinge. Preferably exclusively or essentially
only the arm(s) or cantilever(s) of the hinge reinforcement element are extending
outward from the base plate or base block. In such an arrangement the mechanical coupling
section between the hinge reinforcement element and the frame element is shifted toward
the center of the frame element with respect to the location of the pivoting axis,
such that the mechanical stability of the hinge connection is improved. In particular
when the frame element also comprises door-side bearing elements having a receptacle
for receiving the pivot or pin of the hinge axis, the mechanical load from the hinge
connection is distributed to the periphery of the frame element as well as to the
frame element section located radially inward from the frame element periphery.
[0017] In case the hinge reinforcement element additionally comprises at least one stop
element for limiting a pivoting range of the hinge, the stop element also participates
in the improved mechanical load distribution onto the frame element by the hinge reinforcement
element. By providing the stop element, the mechanical load caused at the maximum
opening angle of the door (when mounted at the laundry machine) is not directly acting
on the frame element, the outer cover or the inner cover of the door. Preferably at
least one of said stop elements is arranged at an arm of said hinge reinforcement
element at which one of said door-side bearing elements is arranged and/or at least
one of said stop elements is acting on an arm of the body-side bearing element to
restrict the angular movement of the body-side bearing element at a predefined opening
angle.
[0018] According to an embodiment a sleeve is inserted in a pivot hole of at least one of
said at least one body-side bearing elements and/or at least one of said door-side
bearing elements. The sleeve is adapted to receive the or one of the at least one
pivot elements (e.g. pivot or pin) free of clearance and/or in a locking or friction
fit manner. In this way, when the door is mounted at a laundry machine, there is no
play or a significantly reduced play between the door and the laundry machine. And/or
when the pivot or pin is inserted into the body-side bearing element(s) and/or door-side
bearing element(s) due to the sleeve, the pivot element is axially secured and cannot
slip out of the bearing element after being inserted during the mounting process.
Preferably no additional fixing or locking means is required to prevent an axial shift
or slide-out of the pivot element that may eventually result in a disconnection of
the hinge connection.
[0019] According to a preferred embodiment at least one of said door-side bearing elements
is provided at the frame element and at least one of said door-side bearing elements
is provided at said hinge reinforcement element. As mentioned above, the multiple
door-side bearing of the pivot connection provides a wide-area distribution of mechanical
load from the hinge connection to the frame element directly and indirectly via the
hinge reinforcement element.
[0020] Preferably the hinge reinforcement element is a metal element formed of a metal plate
by planking or cutting. The hinge reinforcement element has at least one bent arm
or cantilever, each bent arm or cantilever forming or comprising one of said door-side
bearing elements. In this way a mechanically highly stable hinge reinforcement element
can be formed by simple and cost saving manufacturing steps. This effect is further
exploited in that also at least one of said stop elements is formed by the metal plate,
for example as a bent protrusion extending form said metal plate, in particular extending
from the bent arm of the metal plate.
[0021] In a further embodiment the frame element comprises an outer frame member and an
inner frame member. When the outer and/or inner cover is mounted on the frame element,
the periphery of the inner and/or outer cover is supported by the outer frame member
and an inner region of the outer and/or inner cover is supported by the inner frame
member. Preferably the outer frame member and/or the inner frame member are formed
as ring-shaped elements or essentially ring-shaped elements. In an additional or alternative
embodiment the outer frame member and the inner frame member are connected to each
other by at least one spoke. Preferably the inner frame member is at least locally
abutting at an inner region of the inner side of the outer and/or inner cover.
[0022] Preferably at least a portion of the frame element is a hollow structure comprising
a plurality of ribs running in different directions. In particular the frame element
has an outer frame member which is formed of a rib construction.
[0023] Reference is made in detail to preferred embodiments of the invention, examples of
which are illustrated in the following figures, which show:
- Fig. 1
- a perspective, exploded view of a door for a dryer,
- Fig. 2
- a perspective, exploded view of the dryer door shown in Fig. 1,
- Fig. 3
- a perspective detail view showing a portion of the door frame having a hinge mounted
thereto,
- Fig. 4
- different perspective views of a hinge reinforcement element shown in Fig. 3,
- Fig. 5
- a perspective, exploded view of another embodiment of a dryer door, and
- Fig. 6
- a perspective detail view of mounting the door hinge to a frame of the second embodiment
showing in Fig. 5.
[0024] Fig. 1 shows an exploded perspective view of a dryer door 1 according to a first
embodiment. The loading door 1 is formed in a sandwiched construction by an inner
frame 4, that is covered on the outside by an outer cover or outer shell 2 and that
is covered on the inner side by an inner cover or inner shell 6 (with respect to the
mounted state when the door is mounted at a loading opening of a dryer). The loading
door 1 is pivotable mounted to a body of a dryer (not shown) by a hinge 8. In a similar
way as in
EP 2 147 996 A1, with respect to a loading opening of the dryer, the hinge 8 can interchangeably
be provided on the left or right side of the loading opening and thus on the left
or right side of the door 1. The figures show providing it on the right side. For
changing the door suspension between the left and right side (or vice versa), the
orientation of the inner shell 6 is maintained, while the hinge, the outer shell 2
and the frame 4 are rotated by 180 degree when looking from the outside to the front
face of the door 1. As can be seen, the inner shell 6 has mirror symmetry with respect
to the vertical axis - seen when the door is in the mounted state at the dryer.
[0025] The hinge 8 is formed by a body bearing 10, a pivot 12, two bushings 14, two bearing
blocks 40 arranged at the periphery of the frame 4 and a reinforcement plate 42 mounted
or to be mounted on the peripheral area of the frame 4.
[0026] The outer shell 2 has a grip recess 16 or grip depression with an opening 18 through
which a pivotable grip part is inserted in the mounted state (not shown). At the opposite
side with respect to the grip recess 16 two passages 20 are formed at the periphery
of outer shell 2. When pivoting the door 1 in a mounted state, i.e. when body bearing
10 is fixed to the loading opening frame of the dryer, then the hinge arms 76 (see
Fig. 3) of the body bearing 10 can freely swing back and forth through the passages
20.
[0027] The inner shell 6 has an inclined dome 22 which in the mounted and closed state of
the loading door 1 bends out towards the loading opening and deflects the laundry
rotated in the drum towards the inner side of the drum. At the periphery the inclined
dome 22 is surrounded by a mounting flange 24 used to fix the components 2, 4 and
6 of the sandwiched door 1 together. Along the mounting flange 24 spatially distributed
holes 26 each with a reinforcement structure are provided. When mounting the door
parts together, the outer shell 2 is snap-fitted onto the frame 4. For mounting the
inner shell 6 to the frame 4, screws are inserted from the front face of the inner
shell (the side facing towards the inner drum when mounted) through the holes 26 and
into blind bores 48 provided at periphery of the frame 4 at locations mating with
the positions of holes 26. The screws are screwed into the blind bores 48 to fix the
inner shell 6 to the frame 4. Mirrorsymmetrically on both outer sides, the inner shell
6 has cut outs 28 which are provided for the hinge arms 76 of the body bearing 10
such that they can freely swing when the hinge connection between the door 1 and body
of the dryer is established.
[0028] Between the cut-outs 28 an aperture 30 is provided through which a locking bolt (not
shown) pivotable passes, wherein the locking bolt is connected to the pivotable grip
such that the door 1 can be locked or unlocked at the loading opening frame of a dryer.
In mounted state, the locking bolt passes through the left aperture, while the hinge
arm swings through the cut outs 28 on the right side - or vice versa depending on
the hinged side.
[0029] The frame 4 is formed of an outer ring 50 and an inner ring 52, wherein the outer
and inner ring are connected by a plurality of spokes 54 that run radially in this
embodiment. The outer ring 50 is formed of a ripped construction which enables a mechanically
stable but light weight construction. As best seen in Fig. 2, at the hinge side the
frame has a reinforcement structure 56 which means that the radial extension of the
outer ring 50 is wider in the hinge mounting section as compared to the other section
of the outer ring 50. In particular the inner face of the outer ring 50 is closer
to the center of the frame 4 in the angular section of the reinforcement structure
56. In the mounting region of hinge 8 the frame 4 has a reinforced U-frame 60 wherein
the open side of the U-frame 60 is pointing radially outward. The side brackets of
the U-frame 60 are formed by the bearing blocks 40 wherein each of the bearing blocks
40 has a tangentially running hole 41 for receiving the pivot 12. The bearing blocks
40 as well as the bottom bracket (portion between the bearing blocks) of the U-frame
60 is formed of material having a greater wall thickness than the other rib structure
of the outer ring 50. Thus by the U-frame 60 a mechanically stable construction is
provided for receiving the torque moment, push and pull forces transmitted by the
hinge connection under load or if a stroke is exerted (e.g. onto the door).
[0030] Referring to Fig. 3, the hinge 8 is shown in more detail. The body bearing 10 comprises
a base plate 70 by which it is mounted to the loading door frame of a dryer (compare
Fig. 3 in
EP 2 147 996 A1). At the longitudinal ends of the base plate 70 torque claws 72 are arranged. The
torque claws 72 grip into openings at the frame of the loading door opening and provide
mechanical stability against torsion moments and vertical or lateral displacements.
For aligning the base plate 70 and thus the door 1 during mounting the door to the
body of the dryer, alignment pins 74 are provided on the rear face of base plate 70.
The pins 74 extend from the pate 70 and engage with holes provided at the frame of
the loading opening.
[0031] The hinge arms 76 are based at and extend from the front face of base plate 70 (compare
Fig. 1) and have rolled sleeves 78 at the extending ends of the hinge arms 76. A bar
80 is running between the rolled sleeves 78 and provides additional mechanical stability
against relative movements of the tool hinge arms 76 relative to each other. The base
plate 70 and its elements are formed from a single metal sheet by cutting, bending,
buckling and rolling. As mentioned before, during pivoting the hinge arms 76 move
in the clearances provided by the cutouts 28 in the inner shell 6, the open side of
U-frame 60 formed in frame 4 and the passages 20 formed in the outer cover 2.
[0032] As further shown in Fig. 3, the reinforcement plate 42 is fixed by screws 44 to the
frame 4 by screwing the screws 44 into threaded holes 46 provided close to the U-frame
60 but radially shifted towards the center of the frame. The screws 44 are passed
through the screw holes 90 provided in the reinforcement plate 42. "Threaded holes"
in this context may comprise through holes or blind bores that are 'threaded' by screwing
in a threadcutting screw.
[0033] As shown in Fig. 4, cantilevers 92 are provided at longitudinal ends of the reinforcement
plate 42, wherein - similar to U-frame 60 - the cantilevers 92 together with the reinforcement
plate 42 form a U- or C-shape. At the freestanding end each cantilever 92 has a pin
hole 94, wherein the axis of the pin hole 94 runs in a tangential direction relative
to the frame 4 after mounting the reinforcement plate 42 to the frame. At the outer
end of each cantilever 92 a stop claw 96 is provided which is bended to extend in
the longitudinal direction of the reinforcement plate 42. At a predetermined opening
angle of the door 1 relative to the body bearing 10, the stop claws 96 laterally abut
against the inner side of the hinge arm 76 provided at the body bearing 10. Fig. 3
shows the relative position of the body bearing 10 to the reinforcement plate 42 (and
thus frame 4) in which the claw 96 abuts against the inner side of hinge arm 76 (best
seen at the upper hinge connection). Thereby the opening range of the door in the
mounted state is limited to the maximum opening angle to avoid damage to the door's
outer shell 2.
[0034] The hinge connection is provided as follows: Referring to the arrangement as shown
in Fig. 3, the first one of the bushings 14 is inserted into rolled sleeve 78 from
the upper side, such that the collar of the bushing 14 abuts at the upper side to
the upper side of the upper rolled sleeve 78. The second bushing is inserted into
the lower rolled sleeve 78 from below such that the collar of the second bushing 14
abuts from below at the lower edge of the lower rolled sleeve 78. The reinforcement
plate 42 is screwed by the two screws 44 onto the lateral side of frame 4 which is
facing the inner face of the outer shell 2. The rear face of reinforcement plate 42
at least partially covers the side face of the U-frame 60. When the reinforcement
plate 42 is fixed to the frame, the pin hole 94 of the upper cantilever 92 is concentrically
aligned to the tangential hole 41 of the upper bearing block 40, while the pin hole
94 of the lower cantilever 92 is concentrically aligned with the tangential hole 41
of the lower bearing block 40. Then the bushings 14 inserted into rolled sleeves 78
of the body bearing 10 are concentrically aligned to the holes 41 in the bearing blocks
40 and the pivot or pin 12 is inserted from above or below. For example when inserting
pivot 12 from above, it first passes the hole 41 of the upper bearing block 40, the
pin hole 94 of the upper cantilever 92, the hole of the bushing 14 in the upper rolled
sleeve 78, the bushing in the lower rolled sleeve 78, the pin hole 94 of the lower
cantilever 92 and finally the hole 41 in the lower bearing block 40. As the inner
diameter of the bushings 14 is undersized as compared to the outer diameter of the
pivot 12 (i.e. the inner diameter of the bushings 14 is smaller than the outer diameter
of the pivot 12), the pivot 12 has to be inserted against compression forces through
the bushings 14. After inserting the pivot 12 up to the final position, the final
position of the pivot 12 is maintained by friction suspension and friction lock which
the bushings 14 exert on the outer surface of the pivot 12.
[0035] By this hinge connection the suspension area of the hinge suspension is distributed
over a wider area of the frame 4. Thus the hinge connection can withstand higher push,
pull or torque forces acting on the door when the user is opening or closing the door
or unintentionally hits the door. At the other hand by using the reinforcement plate
42 as an additional bearing, the mechanical requirements for the material selection
for the frame 4 are lower. For example less expensive material may be used when injection
molding the frame 4.
[0036] Figures 5 and 6 show a second embodiment for providing the door-side suspension for
the hinge connection. Like elements are indicated by the same reference numerals and
for details reference is made to the first embodiment. The difference between the
first embodiment shown in Figures 1 to 4 and the second embodiment is that in the
second embodiment no bearing blocks 40 are provided at the frame 4. Instead, the frame
4' of the second embodiment has a wider hinge cut-out and provides at the frame-side
periphery of the hinge cut-out a frame fit 100. The frame fit 100 provides a mating
receptacle for receiving a U-block 102 which represents a frame reinforcement element.
The form of the U-block 102 is essentially or approximately C- or U-shaped. The U-block
102 has holes 104 through which screws can be inserted. The screws inserted through
the holes 104 are screwed in to mating holes 101 formed at the front face of the frame
4 such that the U-block 102 is fixed in the frame fit 100 of the frame 4.
[0037] The U- or C-shaped U-block 102 is formed by the brackets formed of upper and lower
bearing blocks 108 and the bottom bracket formed of U-bracket 106. The bearing blocks
108 have tangential holes for receiving the pivot or pin 12 (tangential with respect
to the frame 2 when being mounted thereon). Mounting the hinge to the frame 4 is essentially
the same when using the U-block 102 as if using the reinforcement plate 42 of the
first embodiment. The difference is that the bearing blocks 108 provided at the U-block
102 replace the bearing blocks 40 of the frame 4 and the cantilever 92 with the pin
holes 94 of the reinforcement plate.
[0038] Preferably the U-block 102 is a single cast or monolithic block formed of a material
that has a higher load capability, rupture strength and/or damage resistance than
the material of the frame 4. Preferably the frame 4 as well as the U-block 102 are
formed of molted plastics, wherein the plastic material of the U-block 102 is different
of that of the frame 4 and provides the higher mechanical resistance. As more plastic
material is required for the frame than for block 102, the material for frame can
be selected to be less a stable material which is less expensive as compared with
the material required for the U-block 102.
