Definitions

  • This invention relates to a convected-air cabinet for storage of temperature sensitive goods, particularly for storage of food products.
  • a convected-air cabinet characterized by comprising a front side provided with food access means, an opposed rear side provided with food access means, a base, a roof and spaced side walls interconnecting the front and rear sides, a plurality of regions within the cabinet for storage of food, wherein a first fan is mounted adjacent the base and is arranged beneath a laterally extending cover which extends from the front to the rear side but is spaced from each side, a second fan is mounted adjacent the roof and a laterally extending partition containing an aperture is mounted below the second fan, the laterally extending partition being spaced from the front and rear sides, such that air directed around the first laterally extending cover by the first fan is conveyed within the cabinet to the aperture in the second laterally extending cover and is then directed laterally by the second fan to form air curtains extending downwardly across the front and rear sides.
  • the present invention attempts to overcome at least in part the aforementioned disadvantages of previously known convected-air cabinets.
  • a convected-air cabinet comprising a storage section, and a plant section for housing electrical and mechanical components.
  • the storage section has a chamber for storing temperature-sensitive goods.
  • the chamber has an access door, an upper subsection, a lower subsection, and at least one temperature regulating element disposed in the upper and/or lower subsection, a flow inducer, and a means to direct airflow to one or more corners of the chamber.
  • the improvement over the previously known convected-air cabinets stems from the use of a means to direct the airflow to corners of the storage section of the cabinet. This forces more air to the areas previously lacking air movement before becoming turbulent, providing more uniform heat distribution and thus increasing the duration temperature that sensitive goods can be stored in the cabinet.
  • the electrical and mechanical components that are housed within the plant section are for the proper functioning o the cabinet and would be within the understanding of a person skilled in the art to reasonably be included.
  • the components include but are not limited to motors, wiring, data processors, transformers, control systems and monitoring equipment.
