Definitions

  • the present invention relates to an oven door, particularly for household ovens.
  • the cold door has an interspace between the outermost panel, the one which may be touched by the user, and an internal panel.
  • An aspirator normally located in the upper part of the oven, is connected to the interspace, which is in turn connected to the outside by means of lower openings in order to generate a circulation of cold air, drawn from the outside, in the interspace, thus keeping the external panel at a temperature which is substantially lower than that of the internal panel which is closest to the cooking compartment.
  • One aim of the present invention is to provide a cold door, with air circulation, which has smaller dimensions than the conventional doors.
  • Another aim of the invention is to provide a door for household ovens with improved insulation characteristics.
  • an object of the invention is to provide a cold door which can be manufactured without increasing the production costs with respect to conventional cold doors.
  • an oven door characterized in that it comprises a frame adapted to be hinged at an opening of the oven, said frame comprising, from the compartment toward the outside, a first panel and a second panel, said first and second panels being separated by a first interspace, a third panel separated from said second panel by a second interspace, and a fourth external panel separated from said third panel by a third interspace, said second and third interspaces being connected to the outside and to aspiration means, said aspiration means being adapted to allow the circulation of air to cool said panels.
  • a household oven generally designated by the reference numeral 1, of the pyrolytic type, is shown.
  • the oven has a cooking compartment 3 and a front door 5 which is hinged in a downward position so that it can be opened downward to gain access to the compartment, in a per se known manner.
  • the oven also includes an aspiration assembly 7 which is constituted by a fan 9 connected to the upper part of the door 5 by means of a duct 11.
  • the duct 11 has a first series of lower openings 13 and a second series of upper openings 15 which are formed on the front edge of the oven at the door 5 and are connected thereto as described hereinafter.
  • the oven 1 also has a venting system for expelling the combustion residues generated during the self-cleaning operation of the oven.
  • the venting system substantially comprises a catalytic element 17 through which the residues pass before they are expelled from the cooking compartment by means of the venting duct 19.
  • the oven door comprises a frame 21 which is centrally open and is adapted to support a first series of internal panels 23 and an external panel 25.
  • the panels are made of transparent material in order to allow visual inspection of the cooking compartment without having to open the door.
  • the series of internal panels comprises, starting from the side directed toward the compartment 3: a first panel 27 and a second panel 29, separated by a first interspace 31, and a third panel 33 separated from the second panel by a second interspace 35.
  • the panels 27, 29 and 33 are fixed to one another and to the frame 21 by means of metal sections 37.
  • the metal sections have openings 39 at the second interspace 35. Openings 39 are adapted to connect the interspace to the outside.
  • the first interspace 31 is instead isolated.
  • the lower and upper edges of the third panel 33 are also respectively associated with an upper fastening member 41 and with a lower fastening member 43 which cooperate to fasten the third panel and have openings 45 for the passage of air.
  • the fastening members 41 and 43 are constituted by metal sections and have a heat-reflecting surface directed toward the compartment 3 so as to constitute a screen which reflects the heat inward.
  • baffle 47 which substantially embraces the section 43 and is adapted to direct the flow of air which arrives from below toward the outermost panel.
  • the baffle 47 is also provided with openings 49 for the passage of the air in the interspace 35.
  • Door 5 has a fourth panel 51 which is fixed to the outside of the frame 21 so as to define a third interspace 53 with the third panel 33.
  • the third interspace 53 is connected to the outside in a downward position by means of openings (not shown) formed along the lower edge of the frame. In an upward position, the third interspace is connected both to the outside, at the handle 55, and to the openings 13 of the aspiration duct 11.
  • the operation of the oven door according to the invention is as follows.
  • the fan 9 generates a negative pressure in the duct 11 and thus in the third interspace 53; outside air therefore enters both from the lower side of the door and through the handle 55, generating a current through the second and third interspaces.
  • the outer surface of the panel 51 and the handle 55 have a sufficiently low temperature.
  • insulating material 57 is also arranged in the region comprised between the frame 21 and the fixing elements 41 and 43.
  • the particular execution of the second interspace 35 allows to considerably lower the temperature of the door, also by virtue of the presence of the heat-reflecting screen 41 and 43 and of the baffle 47.
  • oven door according to the invention is susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept. All the details may furthermore be replaced with other technically equivalent elements.
  • the materials employed, as well as the dimensions, may be any according to the requirements.
