Definitions

  • the present invention relates to doors for ovens and domestic gas cookers, and particularly to a door with natural ventilation cooling.
  • the typical structure of an oven door includes an outer door and an inner door, both made of punched sheet, with an insulating material inserted therebetween. These two sheets have a central opening, closed by a double glass, which acts as a window so as to able to check the cooking without opening the door. Since this is the portion which causes most of the loss of heat, due to the fact that it can not contain the insulating material arranged in the rest of the structure, various systems have been studied to lower the temperature of the outer glass.
  • the object of the present invention is to provide an oven door which overcomes the above-mentioned limits of complexity and lack of manufacturing adaptability of prior art doors.
  • a first fundamental advantage of the oven door according to the present invention is its structural simplicity, which allows its manufacturing at low costs both for the production of the members and the assembly thereof.
  • a second advantage of said oven door is the great ease of change of its size, since it is sufficient to cut the glasses and the sections of a different size with no need for new tools.
  • the oven door according to the present invention is made up of an outer glass 1 and an inner glass 2 fixed in parallel and spaced relationship onto a pair of side uprights 3 consisting of a section, preferably made of aluminum.
  • Hinges 4 are positioned inside uprights 3, at the lower end thereof, for the connection to the oven base and the conventional opening of the door through a downward rotation around a horizontal axis. Said opening is carried out by gripping a handle 5 mounted on the door near the top thereof.
  • uprights 3 have a substantially U-shaped cross-section, facing outwards, whose external end terminates with a tongue 6 which extends laterally.
  • a groove 7 is formed, at the internal corner of upright 3, wherein the inner glass 2 is inserted.
  • Said glass 2 covers the whole front of the oven, yet it is smaller than the outer glass 1 which extends laterally beyond tongue 6 so as to cover completely uprights 3, to which it is fixed preferably by gluing.
  • the inner glass 2 covers the opening of the oven front, it assures a heat insulation higher than that of a sheet door which conducts heat better. Said insulation may be further improved by applying a heat-reflecting coating to the inner surface of glass 2. Furthermore, said glass 2 can be fixed into grooves 7 so as to be dismountable. thus allowing an easy cleaning also of the surfaces of glasses 1 and 2 facing the hollow space.
  • a second groove may be formed between groove 7 and the point where glass 1 abuts, so as to insert a third intermediate glass which further increases the heat insulation capability of the door.
  • the opening handle 5 in the first embodiment shown in fig. 1 it has an elongated U-shape extending along the full width of the door to the tongues 6 of uprights 3.
  • Handle 5 is preferably fixed to said tongues 6 by means of fasteners, such as screws or the like, which engage the end of handle 5 by going through the outer glass 1.
  • fasteners such as screws or the like
  • handle 5 is not directly fixed to uprights 3 but to a crosspiece 8 which is inserted at the top of uprights 3 in abutment with the top edge of the outer glass 1.
  • This solution avoids the need to make holes in tongues 6 and glass 1, also leaving freedom of width to handle 5, while the vertical position thereof is fixed and an additional member such as crosspiece 8 is required.
  • crosspiece 8 also acts as a "lid" for the hollow space between the two glasses, by closing uprights 3 at the top while leaving only passage holes for the circulation of air.
  • said holes are suitably formed only on the inner and upper side of crosspiece 8, as indicated by the arrows in fig.2.
  • a further embodiment includes the gluing of handle 5 to the outer glass 1, with full freedom of position and size of the handle.
  • the joining surface has an adequate area so as to achieve a sufficiently strong fixing, whereby the gluing will preferably extend to the whole width of the handle.
