Definitions

  • the invention relates to the oven with a drip collection channel in which condensation droplets are collected on the inner pane of the door.
  • a cavity is provided in the body domestic ovens, in which the consumables to be cooked are placed, and a hinged door to seal the cavity.
  • the vapour formed during cooking in the cavity condenses by hitting the inner pane of the door. Drops form on the inner pane that doors the cavity are formed by condensation. At the bottom of the door, there is a reservoir where the drops are collected.
  • the cooking appliance comprises a door for the cooking chamber, a rear wall and a condensation collection device to collect the condensation that drains from the rear wall
  • condensate collection device comprises a collection and guide rail arranged on the door, which collection and guide rail catches condensate draining from the rear side and diverts said condensate in the direction of of a collection container of the condensate collection device arranged on the door.
  • the object of the invention is to eliminate the need for additional collecting and guide rails adapted to the door pane in ovens.
  • an oven comprising a cavity provided inside an casing and confining a cooking chamber, a front wall having a frame being formed from a one-piece metal sheet adapted to the casing and surrounding the outer periphery of the cavity, and a door that is hinged from an inner pane to the casing sealing the outer periphery in the closed position, and in such a way that abuts against the frame.
  • the oven further comprises a bottom profile with a drip collection channel bent to extend forward under the inner pane and formed in the depression structure on the upper part of the front wall facing the inner pane therein. Therefore, during the forming of the front wall in one piece, for example by deep drawing, the drip collection channel can also be cold formed from the metal sheet itself.
  • the drip collection channel in the depression structure can be formed as monolithically or multipartite, or even in a plurality of adjacent cavities.
  • a drip collection channel with high thermal resistance against high temperatures formed on the front wall of the oven during the baking operation is obtained thanks to its monolithic structure.
  • the drip collection channel has a V-like cross- sectional form. Thanks to its cross-sectional form, the drips reaching the bottom profile from the inner door pane are accelerated and directed to the bottom of the channel.
  • alternative shape forms such as u, w may be preferred.
  • the bottom profile includes a bottom bending extension that is bent backwards towards the cavity at a distance from the drip collection channel and on which an air duct is provided. In this way, with a single piece of metal sheet, both the drip collection channel and the air passage, through which the cooling air passes, can be obtained in one operation.
  • the air duct is in the staggered hole form extending along the width of the bottom profile.
  • the staggered hole structure reduces the turbulence effect during the entry of ambient air from the lower part of the cavity.
  • the staggered hole structure consists of a plurality of elongated and adjacent holes.
  • the bottom bending extension is arranged inclined to direct the air duct towards the cavity. In this way, the negative pressure value required for the outer periphery of cooling air from the outside environment is reduced.
  • the bottom bending extension may also be configured in an upright position.
  • the door comprises an intermediate pane parallel and spaced to the inner pane, and a lower holding element that is aligned to the drip collection channel from the inner corner by holding the inner pane together from the bottom.
  • the lower holding element receives the condensation drops accumulated on the inner pane from the lower corner of the inner pane and directs them to the drip collection channel.
  • the lower holding element keeps the inner pane and intermediate pane(s) together at a distance from each other on doors consisting of more than one pane.
  • the lower holding element is preferably made of metal or a high temperature (eg 200C) resistant plastic.
  • the front wall is made of cold-formed, monolithic metal sheet deep-drawn so as to provide a bottom profile that is fixed from one end to the outer periphery of the cavity from an inner edge and from one end to the casing from one lower edge.
  • the bottom profile can be fixed from its inner edge to the lower edge of the cavity outer periphery and from its lower edge to the casing.
  • the bottom profile forms a compact structure with a drip collection channel mounted on the cavity and the casing.
  • the oven comprises a vertically extending threshold between the inner edge of the front wall and the drip collection channel.
  • the vertical threshold ensures that the drip collection channel formed by bending is detracted from the temperature of the cavity and reduces the thermal stresses on it.
  • a preferred embodiment of the invention comprises a first upper bend line extending transversely between the threshold and the drip collection channel, forming an angled transition wall.
  • the upper bend line and the transition wall under the threshold ensure that in case of any splash from the door pane or condensation in the cavity or the front wall frame, the dripping or splashing drops from the threshold to the drip collection channel are accelerated and collected here.
  • the bending angle of the first upper bending line is adjusted perpendicular to the lower corner of the inner pane. In this way, the largest possible transition wall surface area is provided to catch the drippings from lower corner of the inner pane.
  • the outer pane is extended from its lower part in such a way that it at least partially closes the front wall inside the casing. Thus, any condensation drops splashing out of the oven is prevented and the bottom profile is visually closed.
  • the drip collection channel is arranged to extend through the outer periphery width in the bottom profile. In this way, droplet entry into the cavity through the outer periphery is prevented.
  • the drip collection channel may be set narrower or wider than the outer periphery width.
  • a preferred embodiment of the invention comprises a side slot provided by cold forming at the opposite ends of the bottom profile, where a hinge adapted to the door is partially inserted.
  • the side slot facilitates the adaptation of the bottom profile to the hinged door and a more compact structure is obtained thereof.
