Definitions

  • the present invention relates to a refrigerator and / or freezer with at least one located in the interior of the refrigerator and / or freezer separate compartment.
  • Refrigerators and / or freezers are known from the prior art which have so-called chiller compartments in which lower temperatures prevail than in the actual refrigerator compartment.
  • the cold air from the evaporator room, wherein it is the evaporator is a finned evaporator, passed through valve flaps and / or air ducts to this Chillerfach.
  • colder temperatures can be set in the chiller compartment than in the remaining cold room.
  • this construction is expensive and only allows for setting colder temperatures in the chiller compartment.
  • a refrigerator and / or freezer has at least one separate compartment located in the interior of the refrigerator and / or freezer, wherein one or more fans are provided in the interior, wherein the at least one fan is arranged such that it Air duct within the refrigerator and / or freezer at least partially passes through the compartment and / or on the subject and / or the tray over.
  • the at least one blower By this type of air flow by means of the at least one blower, it is possible to selectively apply the separate compartment with a cooling or heat air flow.
  • the temperature may be higher or lower than the temperature in the interior of the refrigerator and / or freezer.
  • the blower can be designed for example as an indoor fan.
  • the arrangement of the blower to the compartment, the air flow within the refrigerator and / or freezer is such that the cold air coming from the evaporator is passed into the compartment and from there into the interior.
  • a simple way, by preferential loading of the compartment in the tray results in a much lower Set temperature than the rest of the interior of the refrigerator and / or freezer.
  • the arrangement of the fan to the compartment, the air flow within the refrigerator and / or freezer is such that the air is sucked from the interior through the compartment. In this case, there is a much higher temperature inside the compartment compared to the rest of the interior.
  • the tray is preferably non-insulated.
  • the arrangement of the fan to the compartment, the air flow within the refrigerator and / or freezer is such that the air flows around the compartment, the compartment is not-isolated.
  • a flow through the compartment is thus not absolutely necessary, since due to the flow around e.g. sufficient heat is removed from the compartment or - depending on the application - less heat is dissipated compared to the interior. It can therefore set a significantly different temperature compared to the internal temperature.
  • the compartment is designed as a closed compartment.
  • a closed compartment can be front-sided by means of a flap or door, e.g. be closed from transparent plastic.
  • advantageous refrigerated goods which should be stored at a different temperature from the cooling temperature of another goods to be cooled, for. to reach the maximum durability.
  • the compartment has closable openings. These openings can be made closable, for example, by means of a slider. This makes it possible to set inside the compartment a deviating from the interior humidity in the tray. Due to different slide positions can therefore also regulate the humidity in the subject.
  • the blower can be arranged in the immediate vicinity of the compartment. As a result, the temperature of the compartment can be directly influenced.
  • Another embodiment is that the fan (30) is located away from the compartment.
  • means for air guidance in the interior of the refrigerator and / or freezer are provided.
  • the means for air guidance may include baffles and / or ventilation ducts or shafts.
  • the means for air guidance comprise one or more flap (s) and / or one or more slides.
  • the cold air distribution and thus the temperature difference between the interior and the compartment can be influenced.
  • the compartment can be designed as a fixed to the inner container of the refrigerator and / or freezer mounted housing or be removed from the device or inner container.
  • the housing may optionally be e.g. be made of transparent or colored plastic.
  • the compartment has a front flap or door. It is preferred if flap or door are made transparent. Just as well, however, the flap or door made of colored plastic.
  • the tray is designed as an extract tray. Such a compartment is particularly well suited for the reception of fruit or vegetables.
  • the pullout compartment may optionally be e.g. be made of transparent or colored plastic.
  • FIG. 1 shows a first embodiment of the refrigerator and / or freezer according to the invention 10. This has a mounted on the back wall foamed evaporator 40, at its upper end as a fan 30 blower is installed. The fan 30 is mounted immediately behind the separate, non-insulated compartment 20.
  • the compartment 20 is located directly below the upper cooling compartment wall of the inner container 14 of the refrigerator and / or freezer and has a front door 24, which consists of transparent plastic.
  • the fan 30 In the embodiment shown here is sucked by the fan 30, the relatively warm, rising air from the interior 12 through the non-insulated compartment 20, which sets in the compartment a comparatively higher temperature than in the interior 12.
  • the extracted from the compartment 20 air is passed by the fan 30 to the evaporator 40 and cooled.
  • FIG. 2 shows a modified embodiment of the refrigerator and / or freezer 10 according to the invention with the same components as in FIG. 1 ,
  • the air cooled by the evaporator 40 is passed through the compartment 20 through the fan 30, whereby a comparatively lower temperature in the compartment 20 is established.
  • the user is free to choose a lower or higher temperature in the compartment 20. Should a lower temperature be desired in the compartment 20, cooler air is passed through the compartment 20 through the fan 30. In the event that a higher temperature than in the interior 12 is to be set in the compartment 20, the warmer 30 rising from the interior 12 warmer air is sucked through the compartment 20 by the fan.
  • FIG. 3 shows a second embodiment of the refrigerator and / or freezer according to the invention 10.
  • the separate, non-insulated compartment 20 is arranged on the bottom side in the interior 12 of the refrigerator and / or freezer 10.
  • the fan 30 is located above the evaporator 40 located on the rear wall.
  • the evaporator 40 is designed as a foamed-in evaporator 40.
  • air duct 50 By means of air duct 50, the ascending from the interior 12 of the refrigerator and / or freezer warm air directed by the fan 30 is guided past the evaporator 40 and cooled. The cooled air is proportionally led back into the interior 12 and the compartment 20 in the episode. The proportionate distribution of the cold air is adjusted by the position of the slide 52.
  • the compartment 20 is designed in the embodiment shown here as an extract tray 26, wherein the extract tray 26 is made of transparent plastic.
  • FIG. 4 shows the in FIG. 3 shown embodiment of the refrigerator and / or freezer 10 according to the invention with slight modifications.
  • the evaporator 40 is designed here as a free-hanging evaporator 40.
  • the fan 30 draws in the air flowing along the free-hanging evaporator 40 and cooling air and passes it back into the interior 12th
  • the compartment 20 which is designed as a pull-out compartment 26 made of transparent plastic, flows through from the sinking from above cold air, wherein the air enters the interior 12 after flowing through the compartment 20 through a rear opening.
  • FIG. 5 shows a further, third embodiment of the refrigerator and / or freezer according to the invention 10.
  • the separate, non-insulated compartment 20 is provided as a closed compartment 20 with top-mounted closable slides 22.
  • the closed compartment 20 has a front flap, not shown, and is intended for receiving refrigerated goods.
  • the warm air rising from the inner space 12 is sucked past the closed compartment 20 and is guided past the foamed-in evaporator 40 located on the rear wall for cooling.
  • the slider 22 can be adjusted inside the compartment 20, the humidity.
  • the slide 22 When the slide 22 is closed, inside the compartment 20 a higher relative humidity is achieved compared to the interior due to the reduced air exchange.
  • By adjusting the slider 22 can be regulated according to the humidity.
  • the adjustment of the slide 22 is done for example via a control or regulation, not shown.
  • FIG. 6 shows in a modification the in FIG. 5
  • the fan 30 passes the cooled air at the evaporator 40 at the closed compartment 20 over, the colder air largely only after flowing around the closed compartment 20 into the interior 12th arrives.
  • Deviating from FIG. 5 has the in FIG. 6 embodiment shown no cover-side slide 22.
  • the air flow around the compartment 20 in the in FIG. 5 and FIG. 6 shown embodiments can be done both above and / or below the tray 20.
