Definitions

  • the present invention refers to the field of household appliances, particularly free-standing and built-in cooking ranges and built-in ovens comprising a upper heating unit comprising at least two tubular heaters.
  • a design of a heating unit of an electric oven and particularly a top broiling unit for use in such an oven has been disclosed in the published document US 3 128 363 A .
  • the disclosed invention is especially adapted for use with a domestic range that has a viewing window in the front edge of the top cooking surface.
  • Two identical tubular heaters extend over the ceiling area almost entirely in a single horizontal plane and are only in the front section bent into two planes. In this manner it is possible for the heaters to maintain the same design and to be fixed to a reflector close to the oven door.
  • each heater has its own flange and during the assembly, both flanges are jointly fixed to the back of the oven.
  • US 2 836 697 A discloses teachings about the electric range equipped with electric tubular heating units of the type to provide heat for both baking and broiling operations. Said document teaches how to provide separate heating unit in the upper portion of the oven for broiling operations, and a heating unit in the lower portion of the oven for baking operations.
  • Such a solution requires two separate power supplies and connectors, thus, render the entire solution cost-ineffective.
  • the tubular heaters may operate separately or simultaneously, thus resulting in food being unevenly cooked.
  • the object as set out above is solved by an oven according to features of the independent claim.
  • the heater which is arranged closer to the ceiling section of the oven, i.e. the upper heater is designed with a higher heating power than the second heater being arranged below said upper heater.
  • the interior of the oven is formed in a manner that each of both upper side corners is provided with a chamfer.
  • said chamfer comprises an inclination in a range of between 20 to 45 degrees relative to the horizontal.
  • the distance between each transversal cross-section of the heater and said chamfer is always the same.
  • the food being cooked in said oven is cooked optimally and uniformly, since the upper tubular heater with a higher heating power is located on the greater distance from the food, being cooked in the oven, compared to the second tubular heater with a lower heating power arranged below said upper heater.
  • the upper heating unit of an oven consists of two tubular heaters 1, 2 arranged one above the other and attached to a common flange 3 being further attached to a back 9 of an oven 5.
  • the tubular heater 1, 2 which lies closer to a ceiling 4 of the oven 5, i.e. the upper tubular heater 1 in the given case, is preferably designed with a higher heating power whereas the second tubular heater 2 of the lower heating power is arranged in a vertical distance under said upper tubular heater 1.
  • the interior of the oven 5 is designed in a manner that each of the upper side corners is formed with a chamfer 6 when viewing in the direction from the door towards the back of the oven.
  • Said chamfer 6 comprises an inclination y preferably extending in the range of between 20 and 45 degrees relative to the horizontal.
  • Each cross-section 7, 8 of the tubular heater 1, 2 lies here at the very same distance x from said chamfer 6.
