[0001] The present invention relates to a refrigerator that can be used safely and wherein
homogeneous air distribution is provided inside the body. Refrigerators comprise an
opening provided inside the body and through which the cold air around the evaporator
is transferred into the body. A fan that transmits the air around the evaporator to
the opening is provided behind the said opening. A lid is disposed on the opening
to prevent the user from directly reaching the fan. Lids with holes thereon are available
in the state of the art. However, these holes provided on the said lids cannot completely
prevent access to the fan and cannot provide sufficient safety against the risk of
an object or a limb sized as the hole getting caught on or going in the said holes.
Moreover, the lid is also required to provide a homogenous air distribution inside
the body.
In the state of the art Japanese Patent Application No.
JP4082925, a lid is explained, that is disposed inside the refrigerator and that at least partially
covers the opening on the body.
[0002] International Patent Application
WO 2006/120099 A1 discloses a refrigerator comprising grooves in a wall of the inner container forming
an air duct which is delimited by a covering plate. The covering plate may be elevated
and comprise openings in its sidewall for the outlet of air.
[0003] The aim of the present invention is the realization of a refrigerator wherein homogeneous
air distribution is provided inside the body. Another aim of the present invention
is the realization of a refrigerator that can be used safely.
[0004] The refrigerator realized in order to attain the aim of the present invention, explicated
in the first claim and the respective claims thereof, comprises a rear wall facing
the door provided on the body, a fan that remains behind the rear wall and an opening
arranged on the rear wall. The refrigerator comprises an imperforate lid that faces
the opening when placed on the body, that prevents access to the opening from the
front side and that has a width at least as much as the opening. The lid is mounted
to the rear wall so as to allow air passage between the rear wall and the lid. In
an embodiment of the present invention, at least one extension is disposed on the
lid seated on the rear wall. The lid is fixed to the rear wall by connecting the said
extension to the rear wall. The length of the extension determines the distance between
the lid and the rear wall.
[0005] In present invention, the gap between the lid and the rear wall does not have a fixed
width around the lid, but has a variable width.
[0006] In the present invention, the lid comprises quadrilateral edges one of which is closer
to the rear wall with respect to the other when the lid is placed on the rear wall.
Edges with different widths are provided on the lid. Thus, the gaps between the lid
and the rear wall vary for each edge.
[0007] In an embodiment of the present invention, the lid comprises an inclined inner surface
that extends towards the edge and that faces the opening when the lid is placed on
the rear wall. Thus, the air blown from the opening is directed towards the edges
of the lid by the curved surface.
[0008] By means of the present invention, a refrigerator is realized wherein the risk of
getting caught on the fan or the risk of an object getting caught on the fan is eliminated
and furthermore the heat distribution inside the body is kept homogeneous.
[0009] A refrigerator realized in order to attain the aim of the present invention is illustrated
in the attached figures, where:
Figure 1 - is the partial schematic view of a refrigerator.
Figure 2 - is the partial schematic view of the refrigerator when the lid is closed
in an embodiment of the present invention.
Figure 3 - is the perspective view of the lid.
[0010] The elements illustrated in the figures are numbered as follows:
- 1. Refrigerator
- 2. Body
- 3. Evaporator
- 4. Fan
- 5. Rear wall
- 6. Opening
- 7. Lid
- 8. Surface
- 9. Extension
[0011] The refrigerator (1) comprises a body (2) wherein items to be cooled are placed,
an evaporator (3), a fan (4) that blows the air around the evaporator (3) into the
body (2), a rear wall (5) that separates the evaporator (3) and the inner volume of
the body (2) from each other, a fan (4) that is disposed behind the rear wall (5),
and an opening (6) that is arranged on the rear wall (5) and that enables the air
blown by the fan (4) to reach the inside of the body (2).
[0012] The refrigerator (1) of the present invention comprises a lid (7) that is mounted
around the opening (6) so as to close the front of the opening (6) and that directs
the air blown from the fan (4) and impacting thereon towards the gaps between the
rear wall (5) and the lid (7) (Figure 1, Figure 2, Figure 3).
[0013] The fan (4) remaining behind the opening (6) cannot be seen thanks to the lid (7)
placed on the opening (6). Moreover, the user is prevented from reaching the fan (4)
from the front of the opening (6). The cold air blown into the body (2) by the fan
(4) flows towards the sides of the lid (7) by hitting the lid (7) and reaches the
inside of the body (2) from between the lid (7) and the rear wall (5). Thus, the air
blown from the opening (6) does not directly contact the foodstuffs to be cooled inside
the body (2) and contacts the foodstuffs inside the body (2) after being distributed
to the sides by the lid (7).
[0014] In the present invention, the lid (7) is mounted to the rear wall (5) such that a
distance remains between the rear wall (5) and the lid (7). The air blown by the fan
(4) reaches the inside of the body (2) through the gaps formed by the distance between
the lid (7) and the rear wall (5).
[0015] In the present invention, a variable distance is provided between the lid (7) and
the rear wall (5). Thus, the said distances predetermined by the producer enable the
air blown by the fan (4) to be homogeneously distributed inside the body (2) and to
be distributed almost equally in every direction from around the lid (7). By means
of the air blown by the fan (4) passing through gaps with different cross-sections,
cold air with the same flow rate is delivered to every direction around the lid (7).
[0016] In the present invention, the lid (7) comprises quadrilateral edges one of which
is closer to the rear wall (5) with respect to the other when the lid (7) is placed
on the rear wall (5). Edges with different widths are provided on the lid (7). Thus,
the gaps between the lid (7) and the rear wall (5) vary for each edge.
[0017] In an embodiment of the present invention, the lid (7) comprises a curved inner surface
(8) that extends towards the edge and that faces the opening (6) when the lid (7)
is placed on the rear wall (5). Thus, the air blown from the opening (6) is directed
towards the edges of the lid (7) by the curved surface (8). The said surface (8) has
an inclination that increases from the center of the lid (7) towards the edge thereof.
[0018] In an embodiment of the present invention, the refrigerator (1) comprises at least
one extension (9) that is disposed on the lid (7) and that enables the lid (7) to
be connected to the rear wall (5). The lid (7) is fixed to the rear wall (5) by connecting
the said extension (9) to the rear wall (5). The length of the extension (9) determines
the distance between the lid (7) and the rear wall (5).
[0019] In the present invention, the lid (7) has edges with different thicknesses from one
another. Different edge thicknesses enable the formation of different gaps between
the edges of the lid (7) and the rear wall (5). Thus, air can be delivered to the
location in the body (2) desired by the producer with the desired flow rate.
[0020] In the present invention, the lid (7) is mounted to the rear wall (5) so as to be
parallel to the rear wall (5). The surface (8) of the lid (7) is parallel to the rear
wall (5).
[0021] By means of the present invention, a refrigerator (1) is realized, that comprises
a lid (7) that prevents direct access to the fan (4), that enables the air to be homogeneously
distributed inside the body (2) and that almost entirely closes the front of the opening
(6).
