Thus, the nutritional value of the foodstuffs is increased and the cooling process continues.
  • the refrigerator comprises the control unit which enables the UV light source to be switched to the active position if the measured foodstuff surface temperature is greater than the predetermined threshold surface temperature. If the measured surface temperature of the foodstuff is greater than the threshold surface temperature, the UV light source is switched to the active position, enabling the conversion of ergosterol to vitamin D. Thus, it is ensured that the nutritional value of the foodstuffs, especially mushrooms containing vitamin D precursor, is increased.
  • the refrigerator comprises the control unit which ensures that if the measured surface temperature of the foodstuff is lower than the threshold surface temperature value predetermined by the manufacturer the heating member is activated so as to increase the surface temperature of the foodstuff to reach the threshold surface temperature predetermined by the manufacturer.
  • the control unit ensures that if the measured surface temperature of the foodstuff is lower than the threshold surface temperature value predetermined by the manufacturer the heating member is activated so as to increase the surface temperature of the foodstuff to reach the threshold surface temperature predetermined by the manufacturer.
  • vitamin synthesis is provided by means of the contact with the UV light emitted by the UV light source. If the foodstuff surface temperature is lower than a predetermined threshold surface temperature, the foodstuff surface temperature is increased by the heating member.
  • the refrigerator comprises a timer which enables the calculation of the time the UV light source is in the active position, and the control unit which enables the UV light source to be switched to the passive position when the target UV application time predetermined by the manufacturer is completed.

  • the refrigerator (1) comprises a body (2); a refrigeration cabin (3) which is provided in the body (2) and wherein the foodstuffs to be cooled are placed; a door (4) which isolates the refrigeration cabin (3) from the outer environment; a UV light source (5) which has an active position where the UV light source (5) emits light onto the foodstuffs and a passive position where there is no light emitted; and a compartment (6) wherein the UV light emitted by the UV light source (5) is sent onto the foodstuffs.
  • the UV light source (5) is disposed in the compartment (6). Thus, it is ensured that the foodstuffs in the compartment (6) come into contact with the UV light.
  • the refrigerator (1) of the present invention comprises at least one temperature sensor (7) which is disposed in the compartment (6) and which measures the surface temperature of the foodstuffs; a heating member (8) which has an open position where the surface temperature of the foodstuff is increased according to the information received from the temperature sensor (7) and a closed position where there is no heating; and a control unit (9) which enables the heating member (8) and the UV light source (5) to be controlled according to the data received from the temperature sensor (7).
  • the temperature sensor (7) the surface temperature of the foodstuffs is measured and the control unit (9) enables the UV light source (5) to be switched between the active position and the passive position according to the surface temperature of the foodstuffs.
  • the refrigerator (1) comprises the control unit (9) which enables the UV light source (5) to be switched to the active position if the measured foodstuff surface temperature is greater than the threshold surface temperature value predetermined by the manufacturer.
  • the UV light source (5) is switched to the active position so as to radiate. Studies show that when the surface temperature of the foodstuffs is between 20°C and 25°C, the highest amount of vitamin D is synthesized as a result of contact with UV light.
  • the refrigerator (1) comprises the control unit (9) which ensures that if the measured surface temperature of the foodstuff is lower than the threshold surface temperature value predetermined by the manufacturer the heating member (8) is activated so as to increase the surface temperature of the foodstuff to reach the threshold surface temperature predetermined by the manufacturer. If the foodstuff surface temperature is less than the threshold value, the heating process is performed.
