Definitions

  • the present invention relates to an oven particularly cooking foods, using tungsten halogen lamps of the type used for lighiting purpose.
  • tungsten halogen lamps intentionally designed to emit prevalently inforared rays or to operate with filters that are prevalently passed throught by infrared radiations.
  • the cooking oven shaped as a parallelepiped wiht opening front door, is provided above and below the cooking floor hob with at least a relevant tungsten halogen lamp like that normally used for lighting purpose arranged in a relevant reflector.
  • the upper reflectors placed above the cooking floor hob and thus the lamps therein accomodated can be regulated in height, in order to obtain the maximum field intensity in respect to the shape and type of food.
  • the reflectors mounting the tungsten halogen for lighting purpose lamps show on the bottom a "V" shaped fold with the vertex faced to the lamps, in order to avoid the return of the reflected rays on the lamps themselves, that could cause their overheating.
  • Such raflectors also have a geometric shape of edged behaviour showing the reflecting surface as an orange peel, got normally from embassed aluminium.
  • the first one belongs to a timer to fix the cooking time and the second one to a switch/regulator to select the lighting of the tungsten halogen lamps and to regulate their power.
  • a microswitch is placed in correspondence to the edge of the front door in order to disconnect automatically the electrical supply of the lamps, as the door is opened, so avoiding troublesome dazzlings.
  • the door is made, at least partially, of translucent material, but screened against luminous rays, to avoid dazzling during the operation of the oven.
  • reference numeral 1 indicates as a whole the cooking oven in accordance with the invention.
  • It has a basically parallelepiped shape and shows a front door 2 that closes a cooking space 3, provided with some lateral opposed ribs 4 placed at different heights, for the support of a metallic grid or of a transparent glass plate 5 acting as a bearing hob for instance of a food container 6, also in transparent material (see fig. 2).
  • a spit (not shown) can be obviously placed in the cooking space 3.
  • figure 1 it is schematically shown the electric cord 10 of the oven 1, with a plug 11 at the free end.
  • a microswitch 12 is placed, that, pushed by the front door 2, keeps closed the electric circuit of the electric supply when the door is closed, whereas it opens such a circuit as the door is opened, avoiding troublesome dazzlings.
  • the door 2 provided with a handle for grasping 7, has at least an intermediate part 15 in translucent material, but screened against luminous rays, to avoid dazzling during the operation of the oven.
  • knob 13 of a timer to fix the proper cooking time for each food
  • knob 14 of a switch/regulator that selects the lighting of the tungsten halogen lamps 8, and controls their power.
  • the tungsteen halogen lamps 8 are accomodated (two in the example referred in the annexed figures) positioned in suitable casing reflectors 9.
  • the upper reflectors 9, and therefore the relevant tungsten halogen lamps, are regulated in height in the oven space 3, by for instance, toothed slices 19 to which stop gears 20 bound to the reflectors 9 are connected, as schematically shown in fig. 3.
  • the height regulation of the upper reflectors 9 permits to get the maximum field intensity in respect to the shape and time of the food to be cooked.
  • the tungsten halogen lamps 8 are normal lighting lamps thus advantage is taken of their full radiation spectrum, that also includes the visible part.
  • the reflectors 9 show in section (see fig. 2) a geometric shape of edged behaviour, and have on the bottom a "V" shaped simmetric fold 17 with the vertex at the side of the lamp itself, in order to avoid the return of the reflected rays on the lamp, taht could cause its over heating, and consequently a premature lamp life end.
  • Internal reflecting surface of the reflectors 9 has a geometric shape of edged behaviour like an orange peel 18, as schematically seen in figure 3, and it is got, for instance, from embossed aluminium.
  • the geometry of the reflectors 9 and the particular conformation of their reflecting surface 18 lead to a scattering of the rays emitted from the lamps 8, and thus to a better uniformity in distribution of the same on foods to be cooked.
  • a surprising performance of the appliance is the treatment of the frozen foods, for which the defrosting time is shorter than that of a microweve oven, comparable for power and size.
  • tungsten halogen lighting purpose lamps 8 have low cost and limited dimensions; they are largely available in the ordinary shops and supermarkets, they are easily mountable so the user can personally replace them without tools in case of failure, or taken down for eventual cleaning.
  • Browning elements are introduced into the cavity of known microweve ovens to improve the appearence of the cooked food.
  • the antenna and the stirrer are placed to distribute adeguately the microwavs generated in a magnetron (non shown in figure 1 situated beyond the knobs of the timer and the switch/regulator as laid down in a ordinary microwave oven).
  • the cooking space of the oven is not the cavity, where the food is cooked by the combination of microwave and luminous energies.
