  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • Another aim of the present invention is the realization of a refrigerator having a moving illumination module which is detachably attached to the crisper.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
