Definitions

  • the present invention relates to a combination of means intended to reduce the temperature at the level of the control panel in so-called electronic domestic ovens, that is to say those comprising active electronic components for controlling their operation.
  • the invention applies to all domestic ovens. It is particularly advantageous in 1 pyrolysis ovens in which the carbonization temperature reaches 500 ° C.
  • the main purpose of this invention is to allow the use of such components cost much lower than those specially manufactured for advanced techniques using parts subjected to significant thermal stresses.
  • the present invention aims to remedy these drawbacks and, to this end, it relates to a combination of means intended to reduce the temperature at the level of the control panel so as to allow the use of electronic components of large series, of low cost and supply easy, fast and certain.
  • the combination of means according to the invention is characterized in that it comprises a linear air inlet provided between the lower edge of the control panel and the linear mouth for diffusing the extracted air as well as a box with conductive walls. protecting the rear of the control panel by creating a closed volume thermally insulated by cooling its walls with the flow of fresh air admitted.
  • the oven shown, reference 1 conventionally comprises an enclosure 2 or muffle fixed .. suitably on a carcass 3 serving as a body.
  • the oven is closed at the front by a tilting door 4 locked by a retractable handle 5.
  • the oven will include a floor heating resistor 6, a roof heating resistor 7 and a rear fan 8 with its peripheral resistance 9
  • the carcass is placed in a cabinet 10, the walls 11 of which form an almost closed volume. As the case may be, this volume is opened by its rear face according to top 12 and bottom 13 passages forming a chimney.
  • a group of aspira-; centrifugal tion 15 which draws in the interior air from the bottom to discharge it to the outside by a flat duct 16 formed by two converging walls 17 and 18 opening to the outside by a linear diffusion mouth 19 arranged under the lower edge 20 of the control panel 21.
  • the extracted air comes not only from the different openings provided in the carcass, but also from the top and bottom passages 12 and 13.
  • a linear air inlet 22 disposed between the lower edge of the strip 21 and the linear diffusion mouth 19 through which the extracted air is discharged.
  • This air inlet also makes it possible to ensure sufficient air flow in front of the control panel 21 to participate in the conduction cooling.
  • a closed box 23 sealingly defining a stationary air volume 24 at the rear of the control panel 21.
  • This box comprises a vertical wall 25 parallel to the strip 21 and a horizontal wall 26 delimiting with the upper wall 17 from the flat ejection duct 16, a shallow flat channel 27 for the passage of admitted fresh air.
  • the box 23 is closed laterally to produce a completely stationary air volume.
  • the fresh air benefits in addition to the separation by the insulation curtain formed by the air stream 28 leaving the exhaust outlet 19. This insulation avoids the mixing of the heated air in contact with the front face of door 4 with the fresh air coming from the upper space and admitted by the air inlet 22.
  • the path of the fresh air continues towards the suction unit 15, a path during which it forms a curtain of thermal insulation sufficient to protect the vertical wall 25 of the box from temperature rises.
  • the box 23 is therefore perfectly isolated from the superheated air.
  • the internal temperature of the volume of occluded air will not exceed the resistance limit of current electronic components, even in the phase of carbonization of fatty residues during which the temperature of the enclosure reaches 500 ° C.
