[0001] The present invention relates to a refrigerator comprising an illuminated crisper
which increases the vitamin values of the vegetables and fruits therein and which
keeps the vegetables and fruits fresh.
[0002] Foodstuffs such as vegetables, fruits, etc. which are stored in refrigerators for
a long time start to lose their freshness in the course of time. The researches show
that some foodstuffs subjected to lights especially at certain wavelengths and in
colors such as blue, orange, green, etc. can be stored and keep their colors for a
longer time with increased vitamin values. It is observed that different types of
vegetables and fruits in different colors remain fresh for a longer time under lights
at different wavelengths. Therefore, in the state of the art refrigerators are developed,
comprising crispers wherein light sources in different colors are simultaneously or
synchronously operated to simulate color tones closest to the sunlight.
[0003] In the state of the art Patent Document No.
AU2016344962B2, a refrigerator is disclosed, having a compartment wherein the sunlight is simulated
as a result of the operational relation between the two light sources at two different
wavelengths in different steps.
[0004] In the state of the art refrigerators comprising said illumination units and LED
light sources in different colors, the sunlight transition is tried to be carried
out by operating one or more than one light source in different colors in the crisper;
however, the real sunlight transition cannot be achieved.
[0005] The aim of the present invention is the realization of a refrigerator comprising
an illuminated crisper wherein the light transition is carried out as close as possible
to the real sunlight cycle.
[0006] Another aim of the present invention is the realization of a refrigerator having
a moving illumination module which is detachably attached to the crisper.
[0007] The refrigerator of the present invention comprises a crisper wherein the vegetables
and fruits are placed, a housing which is provided on the walls in the crisper, and
an illumination module having at least one claw which is detachably attached to the
housing.
[0008] The illumination module is positioned in the crisper together with a motor, a shaft
connected to the motor, at least one light source, a printed circuit board whereon
preferably the light source is disposed, and a glass having at least two colors whereon
the sunlight can be simulated.
[0009] The refrigerator of the present invention further comprises a control unit which
enables the motor to trigger the shaft such that the light source sweeps the colors
on the glass in an order predetermined by the producer.
[0010] According to the order predetermined by the producer, first the shades of blue are
generated in order to simulate the sunlight in the morning hours, then the whitish
shades of blue in order to simulate the bright white of the sun in the noon, then
the color red to simulate the orangey sunlight in the afternoon hours, followed by
the color black to simulate the night.
[0011] In a preferred embodiment of the present invention, the glass is circular or spherical
and is attached to the illumination module so as to cover the part of the illumination
module facing the crisper.
[0012] The illumination module is in the form of a bowl which is suitable to be positioned
together with the motor, the light source, the shaft and the glass such that the light
source is placed inside so as to be covered by the glass.
[0013] In an embodiment of the present invention, one half of the glass is coated with a
black film and the other half with a colored film containing gradations in blue, red
and green.
[0014] In another preferred embodiment of the present invention, one half of the glass surface
is dyed with black masterbatch and the other half with blue, red and green masterbatch.
[0015] In an embodiment of the present invention, the shaft connected to the motor rotates
the glass and the colored and black film layer thereon clockwise or counterclockwise,
and thus the glass coated with the colored and black film rotates over the light source
around the central point which is the point thereof in contact with the shaft and
makes a full round. By moving the glass, the light source sweeps the day and night
colors on the glass and simulates a normal sunlight cycle in the crisper.
[0016] In another embodiment of the present invention, the shaft connected to the motor
triggers the light source, and the light source makes a circular movement by sweeping
all the colors on the glass. Thus, the light source makes a circular sweeping movement
with a diameter smaller than the diameter of the glass and simulates the day cycle.
[0017] In a preferred embodiment of the present invention, the light source is at least
one white LED light.
[0018] In a preferred embodiment of the present invention, the illumination module comprises
a barrier so as to partially surround the light source. Said barrier prevents the
light leaks from the light source towards the parts other than the glass surfaces.
[0019] The refrigerator realized in order to attain the aim of the present invention is
illustrated in the attached figures, where:

[0021] The refrigerator (1) comprises a body (2); a crisper (3) which is disposed in the
body (2) and wherein the vegetables and fruits are placed; at least one light source
(4) which emits light into the crisper (3); and a glass (6) which is positioned so
as to cover the light source (4) and which has at least two colors to simulate the
sunlight.
[0022] The refrigerator (1) of the present invention comprises a shaft (9) which is connected
to the glass (6) or the light source (4), a motor (8) which enables the shaft (9)
to be moved, and a control unit (10) which enables the motor (8) to trigger the shaft
(9) such that the light source (4) sweeps the colors on the glass (6) in an order
predetermined by the producer.
[0023] The refrigerator (1) of the present invention comprises the light source (4) which
emits light into the crisper (3) and the glass (6) which has at least two colors thereon
so as to cover the light source (4). The glass (6) or the light source (4) is connected
to the shaft (9), and the motor (8) triggers the shaft (9). When the motor (8) triggers
the shaft (9), the glass (6) or the light source (4) moves such that the light source
(4) sweeps the colors on the glass (6) in the order predetermined by the producer.
For example, when the shaft (9) triggers the glass (6), the glass (6) starts to rotate
and the light source (4) sweeps the colors on the moving glass (6) in order. When
the shaft (9) is connected to the light source (4) and the shaft (9) triggers the
light source (4), the light source (4) makes a circular movement so as to sweep the
colors on the glass (6) in order.
[0024] In an embodiment of the present invention, the refrigerator (1) comprises a control
unit (10) which enables the glass (6) to be rotated over the light source (4) clockwise
or counterclockwise or such that the light source (4) sweeps the colors on the glass
(6) in an order so as to simulate the day cycle. Thus, when the glass (6) moves over
the light source (4) or when the light source (4) is moved so as to sweep the colors
on the glass (6), the colors on the glass (6) are swept so as to simulate the sunlight.
[0025] In an embodiment of the present invention, the refrigerator (1) comprises an illumination
module (11) wherein the motor (8), the light source (4) and the glass (6) are mounted
together; at least one claw (12) which is provided on the illumination module (11);
and at least one housing (13) which receives the claw (12). Thus, the components which
move in the crisper (3) so as to simulate the sunlight are placed into the crisper
(3) together, and an illumination module (11) which is detachably attached to the
crisper (3) is obtained.
[0026] In an embodiment of the present invention, the refrigerator (1) comprises a glass
(6) which is circular and which is coated with a film (5) the half of which is black
(S) and the other half red (K), blue (M) and green (Y), and the white LED light source
(4). Thus, all the light hues in a day including the night are provided on the glass
(6), and when the white LED light source (4) sweeps the colors on the film (5), the
day cycle is simulated.
[0027] In an embodiment of the present invention, the refrigerator (1) comprises a control
unit (10) which ensures that a full clockwise or counterclockwise round of the glass
(6) over the light source (4) is 24 hours.
[0028] In an embodiment of the present invention, the refrigerator (1) comprises a control
unit (10) which, upon the movement of the glass (6), stops the movement of the glass
(6) for 12 hours when the glass (6) surface coated with the black (S) film (5) completely
overlaps the light source (4) after the glass (6) surface coated with the colored
film (5) completes its round over the light source (4). Thus, when the shaft (9) triggers
and moves the glass (6) and the light source (4) sweeps the moving glass (6), no energy
is spent to simulate the night (darkness) at the end of the 12-hour daylight step,
and when the light source (4) and the glass (6) surface coated with the black (S)
film (5) completely overlap, the motor (8) stops the shaft (9) and the glass (6).
In this embodiment, after the 12-hour darkness cycle is completed following the stopping
of the glass (6), the control unit (10) moves the glass (6) to the initial position
with respect to the light source (4).
[0029] In an embodiment of the present invention, the refrigerator (1) comprises a control
unit (10) which turns off the light source (4) after the light source (4) sweeps the
glass (6) surface coated with the colored film (5) for 12 hours so as to simulate
the daytime hours. Thus, energy saving is provided while simulating the darkness.
[0030] In an embodiment of the present invention, the refrigerator (1) comprises a barrier
(7) which is positioned so as to partially surround the light source (4) in order
to control the light leaks from between the glass (6) and the light source (4). Thus,
all the light emitted by the light source (4) is directed towards the glass (6) and
a more intense light is provided in the crisper (3).
