Definitions

  • the invention relates to a refrigerator and / or freezer with at least one arranged inside the refrigerator storage compartment in which rule in the operation of the device other temperature and / or humidity conditions or are adjustable than in the refrigerator.
  • Moisture-based storage systems include chiller compartments, BioFresh compartments (0 ° C zones), fan independent refrigeration compartments, refrigerated trays over air ducts of the appliance, compartments with separate heating, trays with slider for humidity control, trays with slider for temperature control, and the like.
  • Examples of other durability-extending storage concepts include vacuum trays, special-purpose trays, special-coated trays, compartments with filters, and the like.
  • the object of the invention is to provide a storage compartment which provides high air humidity values at a temperature which is optimal for the stored product, without the formation of condensation water. Furthermore, the described gas and odor impairment should be prevented by a minimum air circulation. Preferably, a simple humidity adjustment should be possible.
  • the storage compartment has an opening in the cooling chamber, wherein a cover is provided, which covers the opening, and wherein between the opening edge and the cover a teilumfhackmaschine or full-scale gap is formed, so despite the cover an air exchange between the storage compartment and the refrigerator can take place.
  • an extension over a substantial part is understood to mean an extension over at least half or at least two-thirds of the circumference, or, if the opening has a plurality of side edges, an extension over all side edges to one or at most two.
  • a full extent designates an extension over the entire circumference of the opening.
  • the opening faces up.
  • the storage compartment is free in the cold room and can be removed as a whole. It may be, for example, a cuboid, removable box.
  • the storage compartment is extendable by guide means. It may be an extendable drawer, which may also be cuboid.
  • spacers are provided on the cover and / or on the storage compartment to prevent the cover rests directly on the opening edge.
  • these spacers are adjustable, so that the distance between the cover and the opening edge can be adjusted.
  • the cover is a removable hood.
  • the side walls of the hood may overlap the walls of the storage compartment adjacent the opening and the hood may be larger than the opening.
  • an extendable storage compartment can be provided that it is the cover to a cover or that one side of the cover is designed as a flap.
  • the storage compartment and / or the cover are preferably thermally insulated over the entire surface.
  • the walls of the storage compartment and the cover may comprise an insulating layer of a foam material.
  • a humidifier and / or a heating element and / or a separate cooling element for the storage compartment are provided.
  • the humidifier and / or the heating element and / or the cooling element may for example be arranged in or on a wall of the storage container or the cover, for example at the bottom of the storage container.
  • the heating element and / or the cooling element can be, for example, a thermoelectric element.
  • the heating element may also be, for example, a resistance heater.
  • In the cooling element can it is, for example, an air flow channel or evaporator (section) assigned to the compartment.
  • Suitable humidifiers include, for example, ultrasonic atomizers or electrostatic atomizers.
  • an additional ventilation gap or the like is provided for the storage compartment, which can be reversibly and preferably continuously closed by means of a diaphragm and preferably a slider.
  • the gap can be arranged in a wall of the storage container or the cover, for example in a side wall of the storage container.
  • Advantages of the embodiment of the invention include: No formation of condensation, so that the storage compartment described over known solutions has the advantage of storing food at high humidity without formation of condensation;
  • the storage period for refrigerated goods is increased by high humidity. Disadvantages of previously known solutions in the storage of refrigerated goods at high humidity are avoided; Air and humidity can not escape unhindered from the storage compartment, as in the case of open ventilation sliders;
  • the solution is energy efficient and exerts a low load on the refrigeration cycle of the device, since for storage at high compartment temperatures by the insulated construction and the siphon-like gap of the refrigeration cycle of the device only slightly burdened and energy is saved; There is no gas or odor impairment;
  • a minimum air flow allows air to be exchanged from the storage compartment without drying out the stored goods.
  • Possible arrangements of the inventively formed storage compartment include the formation of a device area as a special storage compartment, the formation of the storage space body of the device as a bell, the formation of part of the storage space body of the device as a bell, the arrangement of the unheated special storage compartment in a device zone, the factory-assembled a removable storage compartment, the training of a retrofit storage compartment or the training of the storage compartment in standard or retrofittable box shape.
  • Possible embodiments of the inventively designed storage compartment include a version with heating and temperature and humidity control (humidity control also manually via mechanics possible), a version with heating and cooling and temperature and humidity control (humidity control also manually via mechanics), the version without heating and without Cooling and with manual humidity control via a mechanism, a design as a removable box, as a drawer or as a compartment with flap.
  • One or more elements of the storage compartment such as e.g. the cover may be components, in particular integral parts of the device itself.
  • the figures show an inventive refrigerator and / or freezer 1, in the cooling chamber 2 an inventively designed storage compartment 3 is arranged in the form of a cuboid removable box. In the storage compartment 3 other temperature and humidity conditions prevail as in the refrigerator. 2
  • the storage compartment 3 is in FIG. 1 shown without cover and has a rectangular bottom surface 4 and four normal standing on the bottom surface side walls 5. By an upwardly facing opening 6, the interior of the compartment 3 to the refrigerator 2 is open. The opening edges of the side walls 5 are indicated by the reference numeral 7.
  • cover 8 is formed to cover the opening 6 so that between the opening edge 7 and the cover 8 a full-circumferential gap 9 is formed in FIG. 3 can be seen.
  • the cover 8 is in the form of a hood and comprises a rectangular top surface 10 and four side walls 11 normally standing thereon.
  • spacers may be provided on the opening edge 7 of the storage compartment 3 in the drawing.
  • the cover surface 10 of the cover 8 is longer and wider than the bottom surface 4 of the storage compartment 3.
  • the reference numeral 12 denotes a measuring means.
  • Both the walls 4 and 5 of the storage compartment 3 and the walls 10 and 11 of the cover 8 include an entire surface of an insulating layer of a foam material.
  • a humidifier and a large-area heating element 13 are arranged on the floor.
  • the storage compartment 3 shown in the embodiment thus consists of a storage goods container over which a bell-shaped cover 8 is arranged, wherein around the interior of the storage compartment 3, a circulation gap 9 is provided.
  • the bell-shaped cover 8 is made in an insulated version.
  • the side walls 11 of the bell 8 overlap the Lagerfachharidon 5 partially to completely.
  • the cover 8 is not on the tray 3, but a small distance ensures minimal air circulation, so that the formation of condensation and damage from gases and odors are reduced or prevented. By changing this distance between the cover 8 and the tray 3, a regulation of the humidity can be achieved.
  • An additional possibility of regulating the humidity is the arrangement of not shown in the figure planar Regulierschiebern in the storage compartment walls 5 or in the storage compartment floor 4 or 8 in the Abdeckglocke.
  • a Peltier element can also be used.
  • the arrangement of the unheated storage compartment in an existing temperature zone is also part of this invention.
