[0001] The present invention refers to a dishwasher rack provided with cutlery holder support,
in particular to a dishwasher top rack.
[0002] Dishwashers racks are made up of rigid structures made of steel rods that are welded
to each other in interlacement and subsequently plasticised. The dishes are inserted
into the appropriate spaces created by the interlacement of the rods, in such a way
that they maintain, during the washing, a correct position with an inclination of
the surfaces, as regards the washing sprays coming from the sprayers, such as not
to create difficultly reachable zones, directly or by deviation of the same spray.
[0003] Dishwashers racks are built in such a way as to rationalise the arrangement of the
load of dishes inside the racks, since the surface useful for the loading has a limited
size. In addition a very important prerogative consists in the safety of the load
to be washed even when the weight of the latter is considerable.
[0004] Currently dishwashers racks comprise small plastic containers for the cutlery that
are arranged in separate position as regards the rack for the containment of the dishes.
In this way the efficiency of the washing and possible drying of the cutlery is subordinated
to the search and definition of the optimal position of the dishes. Therefore both
the washing and the drying operation of the cutlery are penalised. In addition the
capacity of the current cutlery containers is unavoidably rather reduced.
[0005] A rack for household dishwashers comprising a cutlery holder support suitable to
solve the problems above exposed is described in the patent application EP 1099404.
The rack has a plastic cup shelf connected with one side wall of the same in such
a way as to form, when in operating conditions, with the bottom plane of the rack
an angle smaller than a right angle. The cup shelf is integral with one or two cutlery
holder supports; each cutlery holder support comprises holes for the housing of cutlery
and wide areas for the flow of the washing water and/or the flow of drying air.
[0006] In view of the state of the art herein described, scope of the present invention
is to provide a dishwasher rack provided with a support for cutlery that has an easy
location in the dishes rack.
[0007] According to the present invention, such scope is attained by means of a dishwasher
rack comprising at least a front or back wall, at least a side wall and at least a
cutlery holder support provided with holes for the housing of cutlery and wide areas
for the flow of the washing water and/or the flow of the drying air, characterised
in that said at least one cutlery holder support is connected with said at least one
front or back wall of said rack and it assumes a working position such as to form
with the bottom plane of said rack an angle smaller than a right angle.
[0008] Owing to the present invention it is possible to provide a rack for dishwasher with
a cutlery holder support that is easy to arrange and to remove for cleaning.
[0009] The characteristics and the advantages of the present invention will become evident
from the following detailed description of an embodiment thereof, that is illustrated
as a non limiting example in the enclosed drawings, in which:

[0010] In Figure 1 a part of a dish rack 12 provided with a cutlery holder support 1 according
to an embodiment of the present invention is shown. The cutlery holder support 1,
preferably of plastic, has a rectangular shape and it is provided with a plurality
of internal holes 2 for the positioning of various pieces of cutlery and with wide
areas 30 for the flow of the washing water and/or the flow of drying air.
[0011] The cutlery holder support 1 is preferably located in a corner created by a front
or back wall with one of the side walls 11 of the rack 12; in Figure 1 the support
1 is located in a corner created by the back wall 52 and a side wall 11. The support
is revolvingly coupled to a horizontal rod 50 of the back wall 52 of the rack 12 by
means of snap insertion of said rod 50 into half-cylindrical fixed end housings 13,
known from the Italian utility model No. 00229638, belonging to the support 1.
[0012] The cutlery holder support 1 can be arranged in a rest position C, visible in Figure
2 and in dotted line in Figure 3, in which the support 1 is substantially parallel
to the back wall 52 and is maintained in said position by the engagement of the housings
13 with the rod 50.
[0013] The support 1 can be arranged in a working position D defined by the inclination
of the same support 1 as regards an axis P parallel to the bottom 40 of the rack 12
so as to form an angle A smaller than a right angle (Figure 3). In said working position
D a projection 53 of the support 1 is engaged with a rod 55 belonging to the side
wall 11 of the rack 12 (Figure 1).
[0014] According to variations of the embodiment of the present invention, one or more cutlery
holder supports 1 can be provided located at each comer created by the side walls
11 and front and back walls 52 of the rack 12; in Figure 4 a part of a dish rack 12
is visible that is provided with two cutlery holder supports 1 located at the corners
created by the side walls 11 with the back wall 52.
[0015] A plastic cup holder rack 3 can also be provided located in proximity of a cutlery
holder support 1 and provided with teeth 4 making up a top rack 5 and of teeth 6 making
up a bottom rack 7; the teeth 4 of said top rack 5 are preferably provided with appendices
8, as visible in Figure 1.
[0016] The shelf 3 can be connected in fixed or mobile way with the side wall 11 of the
rack 12; the shelf 3 is arranged in at least one working position in such a way so
as to form with the bottom plane 40 of the rack 12 at least a first angle smaller
than a straight angle. In the case of the mobile connection of shelf 3 with the side
wall 11 of the rack 12, the shelf 3 is revolvingly coupled to the horizontal rod 10
of the side wall 11 by means of snap insertion of said rod 10 into half-cylindrical
fixed end housings 13 of the shelf 3. The rack 12 is made by means of steel rods that
are welded in interlacement and plasticised so as to define a bottom plane 40 and
at least one pair of side walls 11 with parallel spaces for the containment and positioning
of dishes arranged vertically.
[0017] It is also possible that each cutlery holder support 1 is revolvable toward the outside
of the rack 12 still creating, when in working position, an angle smaller than a straight
angle with the axis P parallel to the bottom 40 of the rack 12.
[0018] In Figure 5 the dish rack 12 provided with the cutlery holder support 1 and an additional
cutlery holder support 100 according to the present invention is schematically shown.
The cutlery holder support 100 is similar to the cutlery holder 1 from which it differs
only in the smaller size and in that it is revolvingly coupled to the horizontal rod
101 of the back wall 52 of the rack 12 by means of snap insertion of said rod 101
into half-cylindrical fixed end housings 13, known from the Italian utility model
No. 00229638, belonging to the support 100. The rod 101 belongs to the central part
of the rack 12 and it is thus located lower than the rod 50. The cutlery holder support
100 can be arranged, as the support 1, in a rest position W, shown in Figure 5, and
in a working position X, shown in Figure 6, in which the support 100 is inclined as
regards an axis P' parallel to the bottom 40 of the rack 12 so as to create an angle
Z smaller than a straight and preferably equal to the angle A formed by the support
1 in working position. When in the working position a projection 103 of the cutlery
holder support 100 engages with the vertical rod 104 of the rack 12.
[0019] According to other variations of the embodiment of the present invention, one or
more cutlery holder supports 100 can be provided, as an alternative or in addition
to one or more supports 1, located in the central part of the rack 12 and connected
with the central part of the front and/or back wall of the rack 12 up to a maximum
of 4 cutlery holder supports 1 and four cutlery holder supports 100.
[0020] The positioning of the cutlery inside the dishwasher allows a more accurate washing
of the same by limiting the contact zone of the tools and by favouring a greater flow
of the washing water. In fact the geometry of the cutlery holder support 1 has solids
and voids in order to limit at most the points of contact between tools and to favour
the drainage of the water.
[0021] In addition such positioning of the cutlery allows to use wide areas for the flow
of a constant heat flow for a more homogenous drying of the same cutlery.
[0022] The position of the cutlery holder supports 1 and 100 allows to lighten the cutlery
rack 12 from the load of cutlery and it eliminates the angles negative to the inlet
of the washing water, thus allowing an overall result of higher efficiency in the
washing and drying with reference to standards.
[0023] The cutlery holder supports 1 and 100 are revolvingly coupled to the back wall 52
so as to be easily removable.
[0024] The dishes rack 12 can be the bottom or top rack of a dishwasher.
