[0001] The present invention relates to a cooling appliance having an ice maker wherein
the ice maker comprises a water damper to damp the flow of the water.
[0002] The modern cooling appliances are provided with automatic ice makers. The ice makers
are provided with a pipe to supply water to the ice maker. The said ice makers are
filled with water and after a certain amount of time, the ice maker is bent via a
motor and the newly formed ice cubes are ejected from the ice maker. The cooling appliance
keeps forming and storing ice cubes until a predetermined level of ice is obtained.
Due to the automatic structure such ice making systems have, the users have limited
possibilities of intervention. As a result of this, as the water is filled inside
the ice maker, some of the water overflows or splashes forming ice near or on the
ice maker. This causes malfunctions and physical damage to the ice maker.
[0003] A prior art publication in the technical field of the present invention may be referred
to as
US2019128595A1among others, the document disclosing a cooling appliance having an automatic ice
maker.
[0004] A prior art publication in the technical field of the present invention may be referred
to as
WO2014084506A1 others, the document disclosing a cooling appliance having an ice maker and an ice
transfer means.
[0005] US8800315B2 discloses a refrigerator having a water supply unit connected to a water supply passage
to temporarily store the supplied water, thereby stably supplying water disposed above
an ice making apparatus.
[0006] An objective of the present invention is to provide a cooling appliance having an
ice maker and a water damper to prevent overflow of water.
[0007] Claim 1 defines a cooling appliance having an ice maker. The ice maker is placed
inside the freezing compartment or inside the fresh food compartment and is isolated
from fresh food compartment so as to keep the surrounding temperature of the ice maker
below zero. In a preferred embodiment, the ice maker is placed on to the rear surface
of a door of the cooling appliance. A pipe is positioned above the ice maker and supplies
water to the ice maker. A water damper is placed above the ice maker and is configured
to guide and damp the water supplied by the pipe. The water damper is in conical shape
with its diameter gradually decreasing from top to bottom meaning that towards the
ice maker. A guide is provided in the form of a protrusion on the inner surface the
ice maker. The guide forms a spiral in a first direction which helps forming a vortex
in the first direction. The helps to prevent the overflow of the water being poured
inside the water damper. By this means, the water is prevented to overflow the water
damper which in time will accumulate in the form of ice on or in close vicinity of
the ice maker. The formation of ice causes the ice maker to malfunction.
[0008] In an embodiment of the invention, a cover is removably placed on to the water damper.
The cover is concave shaped and protrudes upwards. The cover comprises an opening
through which the pipe passes through. By means of the cover, the overflow of water
is further minimized.
[0009] In an embodiment of the invention, the area of the opening is substantially smaller
than the area of the cover. By means of the opening being substantially smaller than
the cover, the pipe after passing through the opening, almost no gap remains in between
the pipe and the cover.
[0010] In an embodiment of the invention, the water damper is made of an elastic material.
The water damper is collapsible reversible upon being pushed on. It reverses in vertical
direction. After the water damper is reversed so as to be inside out, the guide remains
outside the water damper. The guide is symmetrical with respect to the water damper,
therefore forming a secondary guide inside the water damper and the spiral shape.
This time the spiral shape of the guide is in a second direction opposite to the first
direction. By this means, the user may use the same water damper to efficiently damp
the water both in northern and southern hemisphere.
[0011] In an embodiment of the invention, a heater is coiled around the pipe so as to prevent
blockage of the pipe by gradual formation of the ice inside the pipe.
[0012] In an embodiment of the invention, the pipe comprises an outlet wherein the outlet
is at least partly placed inside the cover via the opening. The extension direction
of the outlet is bent with respect to the extension direction of the pipe. By this
means, the water is diverted towards the water damper and to the guide.
[0013] In an embodiment of the invention, the outlet comprises a bottleneck wherein the
cross sectional area of the outlet decreases. By means of the bottleneck, the water
is slowed down and dispersed which in turn helps to prevent overflow.
[0014] In the cooling appliance of the present invention, the ice maker is provided with
the water damper that helps guide the flow of water inside via the guide, preventing
the overflow of water.
[0015] The drawings are not meant to delimit the scope of protection as identified in the
claims nor should they be referred to alone in an effort to interpret the scope identified
in the claims without recourse to the technical disclosure in the description of the
present invention.

[0017] The present invention relates to a cooling appliance (1) comprising; an ice maker
(2) configured to generate ice cubes, a pipe (3) to supply water to the ice maker
(2), a water damper (4) positioned above the ice maker (2) to receive the water from
the pipe (3) and wherein the water damper (4) has a conical shape with a diameter
gradually decreasing from top to the bottom.
[0018] The present invention relates to the cooling appliance (1) further comprising a guide
(5) in the form of a protrusion forming a spiral in a first direction extending in
the vertical direction on the inner surface of the water damper (4) guiding the flow
of the water to flow at least partially along itself. The cooling appliance (1) of
the present invention comprises the ice maker (2). The ice maker (2) is placed inside
the freezing compartment of the cooling appliance (1) wherein the inner temperature
of the freezing compartment is below freezing point of water. It is equally possible
that the ice maker (2) may be located inside the fresh food compartment. In such case,
the ice maker is isolated from the fresh food compartment via a plurality of walls
so as to keep temperature in close vicinity of the ice maker below zero. It is also
equally possible that the ice maker (2) may be located on the rear surface of a door
of the cooling appliance (1). The water is supplied to the ice maker (2) via the pipe
(3). The pipe (3) is connected to a reservoir provided inside or in close vicinity
of the cooling appliance (1) or directly to a main. The water damper (4) is positioned
above the ice maker (2) and is configured to damp and guide the flow of the water
as the water from the pipe (3) flows inside the water damper (4). The water damper
(4) is in conical shape with the diameter decreasing towards the ice maker (2). Therefore,
the water passes through the pipe (3), the water damper (4) and reaches the ice maker
(2) respectively. The conical shape the water damper (4) has helps reduce the splash
of the water as the water emerges from the pipe (3) and contacts the water damper
(4). The water damper (4) comprises the guide (5) on the inner surface of the water
damper (4). The guide (5) is in the form of a protrusion and forms the spiral inside
the water damper in the first direction. The water flows at least partly along the
guide (5) therefore creating a vortex which in turn helps the water flow and reduce
the splash of water outside the water damper (4). By means of the water damper (4)
and the guide (5) the water is prevented to splash which helps reduce accumulation
of water and therefore that of the ice near or in close vicinity of the ice maker
(2) which causes malfunction of the ice maker (2) in the long run. Therefore, easier
operation of the ice maker (2) is provided for the user.
[0019] In an embodiment, the cooling appliance (1) comprises a cover (6) removably placed
onto the water damper (4) wherein the cover (6) comprises an opening (7) provided
thereon through which the pipe (3) is seated. The cover (6) is concave shaped and
protrudes upwards. The cover (6) comprises the opening (7) through which the pipe
(3) is partly inserted. By means of the cover (6), the water is prevented to overflow
the water damper (4) helping reduce the unwanted formation of ice in close vicinity
or near the ice maker (2). The opening on the other hand provides the pipe (3) to
be seated in between the cover (6) and the opening (7). The cover (7) further helps
to eliminate the splash of water and therefore, accumulation of ice near or in close
vicinity of the ice maker (2).
[0020] In a preferred embodiment the area of the opening (7) is substantially smaller than
the area of the cover (6). The area covered by the opening (7) is smaller than the
area covered by the cover (6) which helps to minimize the risk of ice accumulation
near or in close vicinity of the ice maker (2).
[0021] In a preferred embodiment the water damper (4) is removably placed above the ice
maker (2) and that the water damper (4) is made of an elastic material and that the
water damper (4) is collapsible reversible along the vertical direction which upon
being reversed can be placed above the ice maker (2) changing the direction of the
spiral to a second direction opposite to the first direction. The water damper (4)
is made of an elastic material such as silicone or similar. The water damper (4) can
be removed from its place and is configured to be collapsible reversible and put back
into the place so as to be positioned above the ice maker (2). Upon reversing the
water damper (4), the guide (5) will also be reversed. In such case the guide (5)
is configured to remain inside the water damper (4) in the form of a protrusion forming
a spiral in the second direction extending in the vertical direction on the inner
surface of the water damper (4) guiding the flow of the water to flow at least partially
along itself. As the water flows, it tends to form a vortex in counter clockwise direction
in the norther hemisphere. The guide (5) forms a spiral in the first direction corresponding
to the counter clockwise direction. Likewise, the technicians or the user may revers
the water damper (4) in the southern hemisphere, therefore changing the direction
of the spiral to the second direction corresponding to the clockwise direction. By
this means, the water damper (4) can be efficiently used for both norther hemisphere
and southern hemisphere meanwhile minimizing the splash of water.
[0022] In a preferred embodiment the cooling appliance (1) comprises a heater (8) coiling
around the pipe (3). The heater (8) coils around the pipe (3) preventing formation
of ice inside the pipe (3) which in turn will cause the ice maker (2) to malfunction.
[0023] In a preferred embodiment the pipe (3) comprises an outlet (9) via which the pipe
(3) is seated through the opening (8) and wherein the outlet (9) is configured to
bend with respect to an extension direction of the pipe (3). The extension direction
of the outlet (9) and the extension direction of the pipe (3) forms an angle in between.
By this means the outlet (9), water is directed towards the inner volume of the water
damper (4). This helps minimize the amount of water overflowing the water damper (4).
[0024] In a preferred embodiment the outlet (9) comprises a bottleneck. The bottleneck is
used for slowing down and dispersing the water flowing through the pipe (3). This
helps minimize the amount of water overflowing the water damper (4).
[0025] In the cooling appliance (1) of the present invention, the cooling appliance (1)
is provided with the ice maker (2) and the water damper (4) to be used with the ice
maker (2) wherein the water damper (4) is in conical shape to damp and guide the water
therefore preventing overflow of water which in turn causes formation of ice. Another
advantageous effect provided thanks to the reversible collapsible structure the water
damper (4) has is that the water damper (4) can be efficiently used both in northern
and southern hemisphere.
