[0001] The present invention relates to dishwashers, and in particular to a cutlery basket.
[0002] It is known that cutlery baskets for dishwashers usually consist of a vertical container
open at the top with a mesh structure to let the water through, as well as internal
partition walls to hold the cutlery in a substantially vertical position.
[0003] This prior art solution however has the drawback that in the portion of the cutlery
that is in contact with the basket structure or with other adjacent cutlery the contact
surface between said elements and the cutlery is sufficiently large as to allow an
easy clinging of water drops. As a consequence, at the end of the wash and drying
cycle there are still water drops on the cutlery that negatively affect the drying
performance, despite the use of active drying systems such as the recirculation of
moist air through a heat exchanger or its discharge to the outside.
[0004] Moreover, in order to reduce the power consumptions, the latest developments in the
field of dishwashers have led to a decrease in rinse temperatures and this makes even
easier the occurrence of the above-mentioned drawback.
[0005] A cutlery basket structure that reduces this drawback, although not preventing it
altogether, has a structure comprising a lid located on top of the container and provided
with a plurality of individual apertures sized so as to let through the handle of
a piece of cutlery but not its larger end portion. When a piece of cutlery is slipped
through one of these apertures, at the handle end, it remains hanging on the lid with
the handle inside the container and the end portion on the outside. In this way the
contact surface with the structure is just that at the edge of the apertures and there
is no risk of contact between the cutlery.
[0006] However also this arrangement is not free from drawbacks, since there is still the
problem of the water drops clinging at the contact point between the cutlery and the
edges of the apertures, as well as a decrease in the loading capacity of the basket
and a greater manufacturing complexity of the basket requiring a lid with several
individual apertures.
[0007] Therefore the object of the present invention is to provide a cutlery basket for
dishwashers which overcomes the above-mentioned drawbacks.
[0008] This obj ect is achieved by means of a basket having a lid provided with a plurality
of apertures for hanging the cutlery, the edges of said apertures having a pointed
profile that minimizes the contact surface between the cutlery and the basket.
[0009] The main advantage of the present cutlery basket is that of preventing the clinging
of the water drops in the contact regions between the cutlery and the basket while
retaining the ease of production of the basket, so as to improve the drying performance
without any increase in costs.
[0010] Another advantage of this basket stems from the fact that it can be easily applied
even to existing racks, so as to provide an inexpensive upgrade of the dishwashers
already in use.
[0011] Still a further advantage of said basket, in its preferred embodiment, is that of
having a lid structure that is simpler and cheaper to manufacture, which also allows
an increase in the loading capacity.
[0012] These and other advantages and characteristics of the cutlery basket for dishwashers
according to the present invention will be clear to those skilled in the art from
the following detailed description of an embodiment thereof, with reference to the
annexed drawings wherein:
Fig.1 is a front perspective view of a cutlery basket with cutlery arranged therein; and
Fig.2 is a longitudinal sectional view, with two enlarged details, of the basket of Fig.1.
[0013] Referring to figures 1 and 2, there is seen that a cutlery basket 1 conventionally
includes a vertical container 2 with a mesh structure, provided with a handle 3, in
which the cutlery C is introduced through a plurality of apertures 4 (four in the
illustrated example) formed in the lid 5.
[0014] A first novel aspect of the present cutlery basket 1, as previously mentioned, resides
in the fact that the edges 6 of apertures 4 have a pointed profile that minimizes
the contact with cutlery C, as shown in the enlarged details of Fig.2. More specifically,
said pointed profile has a vertex angle smaller than 70° and preferably comprised
between 40° and 50°, such as to minimize the contact surface with cutlery C and to
increase the angles between the latter and edges 6 whereby the water drops can not
cling and thus flow down by gravity.
[0015] A second novel aspect of this basket is given by apertures 4 for cutlery C that rather
than being formed in lid 5 as many individual apertures, i.e. as a grid structure
or the like, are formed as few (in the order of units) simple rectangular apertures
whose edges 6 along the long sides are serrated so as to form many seats for the individual
pieces of cutlery.
[0016] It is clear that the above-described and illustrated embodiment of the cutlery basket
for dishwashers according to the invention is just an example susceptible of various
modifications. In particular, the exact shape, number and arrangement of apertures
4 could be changed according to specific manufacturing needs, e.g. by forming the
apertures longitudinally rather than transversely as shown in the figures.
[0017] Similarly, the material used for basket 1 can be any material suitable in terms of
resistance to water, temperature, detergents and shocks such as plastic materials,
rubber, metal, wood and the like.

(2) in which the cutlery (C) is introduced through a plurality of apertures (4) formed
in a top lid (5) of said container (2), said apertures (4) being sized so as to let
through the handle of a piece of cutlery but not its larger end portion, characterized in that the edges (6) of the apertures (4) have a pointed profile that has a vertex angle
smaller than 70°.
2. Cutlery basket (1) according to claim 1, characterized in that the vertex angle of the profile of the edges (6) is comprised between 40° and 50°.
3. Cutlery basket (1) according to any of the preceding claims, characterized in that the apertures (4 ) are formed in the lid (5) in a number of the order of units and
their edges (6) along the longer sides are serrated.
