Description

    A REFRIGERATOR COMPRISING A STORAGE COMPARTMENT
  • The present invention relates to a refrigerator having a storage compartment that is placed into the fresh food compartment.
  • In order to store foods like meat, chicken, fish that need to be kept at low temperatures in the fresh food compartment and to prolong the storage duration of the foods, the use of ultraviolet lamps is known which are located in the fresh food compartment, enabling the storage duration of the foods to be prolonged by decreasing the microbiologic load of air. During and after the storage process, temperature increases on the foodstuff and/or in the compartment due to the use of ultraviolet lamp. Temperature increase in the storage compartment decreases the sterilization effectiveness of the ultraviolet lamp. Furthermore, the increasing temperature causes sour taste and odor in foods especially in fatty foods like meat due to oxidation and darkening or greening at the surface which creates spoilage perception in the eyes of the user.
  • In the state of the art Chinese Patent Application No. CN2704003, a refrigerator is disclosed, that comprises an ultraviolet ray sterilizing device situated in the freshness-reservation cabinet, that provides energy saving and enables the foodstuffs to be stored for longer time periods.
  • The aim of the present invention is the realization of a refrigerator wherein foodstuffs are stored in a safe manner.
  • The refrigerator realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises at least one fresh food compartment that cools the foods stored therein, a storage compartment placed into the fresh food compartment and wherein the sterilization process is performed, and at least one ultraviolet lamp that is disposed on the storage compartment and that decreases the microbiologic load in the storage compartment. The refrigerator of the present invention comprises a control unit that activates the fan and/or the valve before or after the ultraviolet lamp in order to decrease temperature increase originating from the ultraviolet lamp.
  • Growth of microorganisms on the foods is prevented by decreasing the temperature in the storage compartment by means of the fan and/or the valve that is activated before or after the sterilization process.
  • In an embodiment of the present invention, the control unit cools the storage compartment before the sterilization process by allowing heat transfer between the fresh food compartment and the storage compartment and/or by operating the fan if the measured food surface temperature is greater than the food surface temperature limit value predetermined by the producer. Thus, the storage compartment is prepared for the sterilization process and the temperature inside the storage compartment is prevented from rising uncontrollably during the sterilization process.
  • In an embodiment of the present invention, the control unit enables the food surface to be cooled by opening the valve and/or activating the fan if the food surface temperature measured after the ultraviolet lamp is activated is greater than a food surface temperature limit value predetermined by the producer. Thus, the risk of reproduction of pathogen microorganisms and the increase of microorganisms causing spoilage and oxidation and color changes in the product depending on temperature increase are prevented.
  • In an embodiment of the present invention, the control unit enables the food surface to be cooled by opening the valve and/or activating the fan if the ultraviolet lamp surface temperature measured is greater than a ultraviolet lamp surface temperature limit value predetermined by the producer during the sterilization process. Thus, the temperature on the food surface is prevented from increasing during the sterilization process by cooling the surface of the ultraviolet lamp when it starts operating.
  • In an embodiment of the present invention, the control unit enables the food or the vicinity of the ultraviolet lamp to be cooled by changing the speed of the fan depending on temperature values received from the first temperature sensor and the second temperature sensor. The control unit operates the fan at the fan speed suitable for the measured food surface temperature. Thus, the temperature increase inside the storage compartment is kept under control.

The refrigerator (1) of the present invention comprises a first temperature sensor (8) that detects the temperature of the food (G), a second temperature sensor (9) that detects the temperature in the vicinity of the ultraviolet lamp (4), and a control unit (7) that is configured to provide cooling of the food (G) by means of the fan (5) and the valve (6) depending on the data received from the first temperature sensor (8) before and after the ultraviolet lamp (4) is activated and/or cooling of the vicinity of the ultraviolet lamp (4) depending on the data received from the second temperature sensor (9) when the ultraviolet lamp (4) is activated. By means of the coordinated operation of the fan (5) and/or the valve (6) and the ultraviolet lamp (4), the storing and sterilization processes are realized so as to provide optimum storage conditions. Reproduction of microorganisms on the food due to increase in temperature and increase of oxidation are prevented by decreasing the temperature in the storage compartment (3) which increases as a result of operation of the ultraviolet lamp (4).
  • The control unit (7) performs at least one of the modes of precooling, ultraviolet cooling and aftercooling so that the foods in the storage compartment (3) are not affected by the heat of the ultraviolet lamp (4). In the precooling mode, the control unit (7) enables the food (G) inside the storage compartment (3) to be cooled by actuating the fan (5) and the valve (6) depending on the data received from the first temperature sensor (8) before the ultraviolet lamp (4) is activated. In the ultraviolet cooling mode, the control unit (7) enables the vicinity of the ultraviolet lamp (4) inside the storage compartment (3) to be cooled by actuating the fan (5) and the valve (6) depending on the data received from the second temperature sensor (9) when the ultraviolet lamp (4) is activated. In the aftercooling mode, the control unit (7) enables the food (G) to be cooled by actuating the fan (5) and the valve (6) depending on the data received from the first temperature sensor (8) after the ultraviolet lamp (4) is deactivated.
  • In an embodiment of the present invention, the control unit (7) enables the measured food surface temperature (Tgm) to be lowered by opening the valve (6) and/or activating the fan (5) if the measured food surface temperature (Tgm) is greater than the food surface temperature limit value (Tgl) predetermined by the producer before the ultraviolet lamp (4) is activated. Thus, the storage compartment (3) is cooled before the ultraviolet lamp (4) starts operating and the temperature increase inside the storage compartment (3) during the sterilization process is prevented.
  • In an embodiment of the present invention, the control unit (7) enables the food surface to be cooled by opening the valve (6) and/or activating the fan (5) if the measured food surface temperature (Tgm) after the ultraviolet lamp (4) is activated is greater than the food surface temperature limit value (Tgl) predetermined by the producer Thus, spoiling of the food is prevented by keeping the measured food surface temperature (Tgm) under control and the sterilization effectiveness inside the storage compartment (3) is increased.
  • In an embodiment of the present invention, the control unit (7) enables the food surface to be cooled by opening the valve (6) and/or activating the fan (5) if the measured ultraviolet lamp (4) surface temperature (Tlm), while the ultraviolet lamp (4) is activated is greater than the ultraviolet lamp (4) surface temperature limit value (Tll) predetermined by the producer. Thus, the temperature on the food surface is prevented from increasing during the sterilization process by cooling the surface of the ultraviolet lamp (4) when the ultraviolet lamp (4) starts operating.
  • In an embodiment of the present invention, the control unit (7) enables the food (G) or the vicinity of the ultraviolet lamp (4) to be cooled by changing the speed of the fan (5) depending on the temperature values detected from the first temperature sensor (8) and the second temperature sensor (9).
  • In a derivative of this embodiment, the control unit (7) operates the fan (5) at a fan (5) speed (v1,v2,…) recorded in its memory and predetermined by the producer, corresponding to each food surface temperature interval (Tga1, Tga2,...) predetermined by the producer. Thus, at high temperatures, the cooling operation inside the storage compartment (3) is made effective by operating the fan (5) at high speed and the ultraviolet radiation intensity can be increased safely.
  • In an embodiment of the present invention, the fan (5) is situated on the storage compartment (3).
  • In an embodiment of the present invention, the fan (5) is situated on the fresh food compartment (2).
  • In an embodiment of the present invention, the fan (5) and the valve (6) are placed into the storage compartment (3) so as to cool at least the ultraviolet lamp (4) or the food (G). Cooling effectiveness is increased by means of the fan (5) and the valve (6) that are located close to the lamp (4) or the food (G).
  • In an embodiment of the present invention, the first temperature sensor (8) and the second temperature sensor (9) are infrared sensors.
  • In an embodiment of the present invention, the first temperature sensor (8) is placed at the base of the storage compartment (3) so as to be close to the food (G).
  • By means of the present invention, the ultraviolet lamp (4) that provides sterilization in the storage compartment (3), the fan (5) and the valve (6) are operated in a controlled manner. The temperature increase originating from ultraviolet radiation is directly proportional with the radiation time and the radiation intensity in the fixed time period. Sterilization effectiveness decreases in low radiation intensities and color change occurs on the food surface that is triggered by the temperature increase in high radiation intensities. By means of the fan (5) and/or the valve (6) and the ultraviolet lamp (4) operating interdependently, the temperature inside the storage compartment (3) is kept under control while ultraviolet radiation is increased.
