Technical field of the invention
[0001] The present invention generally relates to refrigerator appliances and in particular
to a refrigerator appliance with an improved door opening device.
Background
[0002] It is known that modern refrigerator appliances are characterized by a generally
flat design of the outer walls, which allows to better integrate them in a kitchen
environment. Recessed door handles are more and more often used in these appliances.
Since no grip parts, nor door opening devices, if any, are visible from the front
and/or side of the refrigerator, an improved aesthetic appearance is achieved.
[0003] Moreover, manufacturing and assembly costs can be remarkably reduced by integrating
and thus hiding inside doors the handles and door opening devices.
[0004] US 7984955 discloses a refrigerator with a recessed handle of the type above. A recess is formed
in any one of an upper portion and lower portion of a door and a shield is mounted
at a front surface of the door, thus defining a handle. The shield also has an aesthetic
function in that it contributes to the aesthetic appearance of the door. A door opening
device is mounted in the recessed handle and is hidden by the shield. The shield may
either be made as a separate component mounted to the door, or integrally formed with
the front wall of the door.
[0005] Also known are door-integrated handles comprising a sheet-metal member formed by
bending starting from a flat plate in order to obtain a U-shaped profile to be fitted
in a door cavity.
[0006] The availability of different solutions to make recessed handles notwithstanding,
there is still a need to find improved solutions in particular as far as aesthetics
and assembly are concerned.
Summary of the invention
[0007] The technical problem underlying and solved by the present invention is therefore
to provide a refrigerator appliance with a recessed door handle that allows to overcome
the drawbacks mentioned above with reference to the prior art.
[0008] This problem is solved by a refrigerator appliance according to the independent claim
1. Preferred features of the present invention are set forth in the dependent claims.
[0009] An idea of solution underlying the invention is to provide a door-integrated handle
assembly comprising a handle element and a cover element configured to be assembled
to one another by way of a combination of snap-fit connectors, as well as guiding
ribs.
[0010] Thanks to this configuration, a precise and stable assembly can be achieved.
[0011] According to an embodiment of the invention, the snap-fit connectors comprise a plurality
of tabs with respective slots formed on one between the cover element and the handle
element, as well as a plurality of teeth formed on the other one between the handle
element and the cover element. The teeth are received in the slots in an assembled
configuration of the door-integrated handle element. The guiding ribs are formed on
side portions of the handle element and the cover element and behave as rails easing
assembly of the cover element onto the handle element and restraining the side portions
of the former.
[0012] This configuration allows to easily and precisely fit the cover element onto the
handle element and snap it to the latter only when assembly is substantially complete.
[0013] Further advantages, features and operation modes of the present invention will become
clear from the following detailed description of embodiments thereof, which are given
for illustrative and not-limiting purposes.

Detailed description of preferred embodiments
[0015] With reference to the figures, a door-integrated handle assembly according to the
invention is generally indicated by reference number 100. In the schematic drawing
of figure 1 the door-integrated handle assembly 100 is shown mounted on a refrigerator
door D of a refrigerator appliance (not shown), e.g. a bottom-mount refrigerator type,
and is associated with the lower edge of the door.
[0016] In the figures, the door-integrated handle assembly 100 is shown with reference to
a three-dimensional coordinate system. A first axis X and a second axis Y that are
mutually perpendicular define a horizontal plane, while a third axis Z defines a vertical
axis along which the force of gravity acts.
[0017] The door-integrated handle assembly 100 comprises a handle element 110 and a cover
element 120 that is configured to be attached to the handle element 110.
[0018] Depending on the configuration of a refrigerator door D and on its position on the
appliance, the handle element 110 may be configured as a top or bottom closing element
of the door D, defining a cavity to be filled with an insulating foam together with
a front wall, a rear wall and a further closing element arranged at the opposite end
of the door in the vertical direction Z.
[0019] According to the invention the handle element 110 extends from the end of the appliance
door in the vertical direction Z and includes a cavity 111 where a user can put his/her
hand to pull the door open and/or to close it.
[0020] The cavity 111 extends in a longitudinal direction X for almost the whole length
of the handle element 110, thus offering a user a wide space to put a hand without
any specific space or position restriction.
[0021] The cavity 111 is formed in a body 112 of the handle element 110. An end portion
113 of the body 112 in the vertical direction Z forms an appendix configured to be
coupled to a front wall and a rear wall of the refrigerator door D to define the cavity
intended to receive the insulating foam. To this aim a plurality of guiding ribs 114
are formed along the periphery of the body 112.
[0022] The cover element 120 is configured as a fascia having a front portion 121 extending
in the longitudinal direction X and side portions 122, 123 extending at the ends of
the front portion 121 in a transverse direction Y perpendicular to the longitudinal
direction X and to the vertical direction Z.
[0023] While the handle element 110 has a structural function within the door D, because
it closes the insulating cavity and provides a grip to open and close the door itself,
the cover element 120 has an aesthetic function in that it is meant to be mounted
on the periphery of the handle element 110 to provide a smooth surface substantially
flush with the surface of the front wall of the refrigerator door D.
[0024] In order to assemble the cover element 120 to the handle element 110 two anchoring
solutions synergistically cooperating with each other have been devised.
[0025] Particularly referring to figure 3 to 6, first and second snap-fit connectors having
matching shapes are formed along the front sides of the handle element 110 and of
the cover element 120. The first snap-fit connectors may e.g. comprise a plurality
of tabs 124 with respective slots 125 formed on the surface of the front portion 121
intended to face the handle element 110. The second snap-fit connectors may e.g. comprise
teeth 115 formed on the handle element 110 in the vertical direction at positions
corresponding to the positions of the tabs 124. In an assembled configuration of the
door-integrated handle element 100, the teeth 115 are received in the slots 125.
[0026] According to an embodiment of the invention, two rows of tabs may advantageously
be formed on the cover element 120 at its top and bottom edges in the vertical direction
Z. Two rows of teeth are correspondingly formed in the top and bottom edges of the
handle element 110.
[0027] It will be appreciated that in order to achieve an equivalent snap-fit assembly the
tabs might alternatively be formed on the handle element 110 and that the teeth might
be formed on the cover element 120.
[0028] It will also be appreciated that snap-fit connectors do not only encompass slotted
tabs and teeth described above, but also equivalent components such as e.g. hooks,
latches and the like.
[0029] In addition to the snap-fit connectors described above, further anchoring means are
associated with side portions 122, 123 of the cover element 120 as well as with side
portions of the handle element 110.
[0030] Particularly referring to figure 4 and 6, first guiding ribs 116 are formed along
the sides of the handle element 110 in the transverse direction Y and second guiding
ribs 126 are correspondingly formed along each side portion of the cover element 120.
[0031] The first guiding ribs 116 of the handle element 110 are spaced apart from the body
112 in the longitudinal direction X so as to define rails adapted to receive the second
guiding ribs 126 of the cover element 120 during assembly. This allows to keep the
side portions 122, 123 of the cover element 120 flush with the door sides and to compensate
possible deformations of the cover element 120 deriving from its manufacturing process.
[0032] According to an embodiment shown in the figures, the guiding ribs 116 of the handle
portion 110 and those of the cover portion 120 may advantageously feature an L-shaped
cross-section, which improves their robustness and ensures a higher assembly precision.
[0033] According to an embodiment of the invention, two parallel guiding ribs, preferably
featuring an L-shaped cross-section, are formed on each side of the handle element
110 as well as of the cover element 120. This configuration offers the advantage of
a more precise assembly in the vertical direction Z.
[0034] The cover element 120 may be made of the same or a different material compared to
the front wall of the refrigerator door and may have the same or a different finishing
and/or texture.
[0035] According to an embodiment of the invention, a door opening device may be associated
with in the door-integrated handle element 100 and housed in the handle element 110.
