Definitions

  • My invention relates to refrigerator cabinet shelves.
  • the shelves of refrigerators as generally constructed are often completely covered- 6 with articles thereby preventing the free circulation of air in the cabinet. This causes an undesirably high temperature in the portion of the cabinet in which the circulation of air is cut off, as the transfer of heat from the space within the cabinet to the cooling unit takes place by aircirculating in the cabinet being cooled 1n assing over the cooling unit and'then absorblng the heat from the articles within the cabinet when it passes over them. Cutting off of the circulation of air in cabinets has been particularly troublesome when fish were stored in a refrigerator of this kind,
  • the object of my invention is to provide an arrangement to prevent fish or other articles on the shelves from coming in contact with the inside walls of the cabinet andentirely covering the shelves so that free circulation of air in the refri erator is maintained.
  • I accomplish this ob]ect by providing a refrigerator cabinet with shelves including spacers which extend about the inner walls of the refrigerator, so as to form a passage for the 2 is an enlarged perspective of the various parts of my improved shelf, and Fig. 3 is a partial elevation in section showing the details of the spacer construction and the arrangement of parts in the cabinet.
  • cooling'units 11 arranged, in the cabinet.
  • the refrigerator cabinet is provided with a shelf construction which prevents articles laced in the cabinet entirely coverin the s elves so as to cut off the circulation of air between the shelves and the cooling unit.
  • the shelves 12 and 13 closely fit the cabinet and include a rectangular frame 14 and longitudinally extending bars 1 5 welded or otherwise connected thereto constituting ,an article supporting grid.
  • shelves 12 of an open framework are supported in the cabinet on abutments 16 extending from the wall of-the cabinet,,and
  • the shelf 13 is provided with legs 17 which rest on the bottom wall of the cabinet so that aircan circulate freely under the shelf.
  • Spacers are provided between the shelves, extending about their periphery so as to prevent articles thereon entirely covering the shelves and thereby cutting off the circulation ofair in the cabinet.
  • a spacer is not placed above the uppermost shelf in a refrigerator construction like the one illustrated, as drip pans are generally retained thereon below the evaporators, but if it is desired spacers can also be placed here.
  • These spacers include a wire network form- I ing a grating 18 extending between a rod frame '19.
  • the frame 19 is formed with outwardly projecting portions. 20, which include in the particular embodiment illustrated, the vertical portions of the frame 19 bent outwardlyvas shown in Fig.
  • this combination provides a construction which prevents articles on the shelf from coming in contact with the walls of the cabinet and entirely covering the shelf, the
  • spacers providing a space all around the sides and under the bottom where the air will be able to circulate freely between the shelves and the inner wallsof the cabinet and insure the proper cooling of articles stored therein.
  • dirt M might be a-tendency for dirt M to accumulate between the spacers and the walls and to this 'end the spacers and the shelves are constructed so as to bereadily removable by merely lifting them out for cleanin of the cabinet and the shelf structure.
