Definitions

  • the present invention relates to a domestic cooking chamber muffle and a domestic cooking chamber equipped with said muffle.
  • the muffle designates all the internal walls of a domestic cooking oven with the exception of an opening intended to be closed by a door.
  • the different walls of the muffle form a parallelepiped with 5 faces and are made of enamel coated sheet and, depending on the type of coating used, they can be automatically cleaned by catalysis or pyrolysis according to known methods.
  • the electric cooking furnaces of the heating resistors are arranged inside the muffle and parallel to the plane of the upper wall and / or to the plane of the lower wall and / or around a ventilation turbine located on the wall of the bottom of the enclosure.
  • Adjustable positioning means are provided on the side faces, steps or racks for example, to have grids or adjustable height plates in the muffle.
  • the muffle is surrounded by a thickness of insulating material and fixed in a suitable niche of a kitchen furniture, or a covering if it is a standing oven, or a cookstove when the oven is associated with a hob.
  • the catering sector has steam ovens whose muffles, made of stainless steel, are heated by a flow of steam circulating in the enclosure and intended for reheating and / or maintaining the temperature of cooked dishes rather than actual cooking of food, in this type of oven the difficulty of cleaning is not as important because of the lower temperature and the absence of projections of burned fat.
  • the object of the present invention is to provide a domestic glass cooking muffle with heating elements inside, especially for but not limited to facilitating its cleaning, reducing insulation, offering new aesthetic possibilities and considering new cooking systems.
  • the invention which consists of a muffle of the type intended to form the inner wall or walls of a cooking chamber for domestic use and having an inlet / outlet opening of the dishes that can be closed by a door, characterized in that said muffle is made entirely of glass, and comprises at least one hole for the passage of at least one heating means intended to be arranged inside the muffle.
  • the assemblies are glass-glass assemblies, made for example by welding or by embedding.
  • At least part of the muffle is made of borosilicate glass.
  • the invention also relates to a domestic cooking chamber of the type comprising a muffle in which the food is cooked, equipped with a door for opening and closing an opening of the muffle intended for the entry and exit of the cooking dishes, the muffle being surrounded by insulating means, and the enclosure conventionally comprising means for heating the muffle, with their control devices, characterized in that the muffle is made entirely of glass and in that the heating means of the enclosure are at least partly located inside the muffle, at least one of which has a hole for the passage of at least one heating resistor.
  • the heating means of the enclosure are of the "rotating heat” type.
  • the muffle can be according to the models, extractable from the enclosure to facilitate its cleaning.
  • the enclosure further comprises a steam cleaning mode, with the equipment necessary for the production of steam and / or hot water inside the muffle and the equipment necessary for the discharge of washing water, as well as a wash command.
  • mittens (1, 2, 3) shown in the accompanying figures are by way of non-limiting example of cubic form but of course other forms are possible such as for example a parallelepiped shape, a cylindrical shape, an enclosure with non-planar walls, for example convex etc.
  • Molding is a preferred technique, and it requires the creation of a metal mold, and a molding furnace equipped with sufficient heating means to bring the glass to a viscous state.
  • the manufacturing method is conventional for molding glass: step of transforming a predetermined volume of glass to the viscous state, filling the mold, cooling and ejection of the piece in the form of muffle.
  • racks (4) are provided and are molded with the walls.
  • a rack-and-pinion system is possible (not shown), in this case the side walls are smooth and / or the rack-and-pinion system can be removable for cleaning.
  • edges of the parallelepiped are preferably of rounded section for reasons of strength and aesthetics, in this case the muffle is obtained by molding.
  • the upper plate (5) is made of glass resistant to very high temperatures about 500 ° C so as to allow the installation of a grill above or below it.
  • This face may be flat or not (for example arched) and placed or welded to the side walls (6, 7) and the rear wall (8) which they can be made of a glass material that does not support very high temperatures.
  • the upper plate (5) rests on the adjacent plates by a recess (10).
  • the preferred but nonlimiting method of cooking used in combination with the muffle according to the invention is the "rotating heat" of the circular heating resistor type (15) arranged around a turbine disposed inside the muffle and driven into rotation by a motor disposed behind the rear wall, so outside the muffle, a hole (9) being provided in the rear wall for the passage of electrical connections and / or the passage of the drive shaft of the turbine.
  • the heating element (s) and / or the turbine may be dismountable for cleaning.
  • This mode "rotating heat” may also be associated with a grill or not.
  • one of the walls of the muffle comprises a hole (not shown) for the passage of the electrical connections of the grill resistor.
  • the oven also comprises the equipment necessary for the production of steam and / or hot water and the necessary connections, arranged outside the muffle, as well as holes or orifices (18, 19 for example) for the inputs and outputs. water and / or steam in the muffle.
  • a furnace according to the invention equipped with a glass muffle whatever the cleaning mode in dishwashers or steam requires a thermal insulation (14) less extensive because the maximum heating temperature prevailing inside the muffle in cooking or cleaning mode remains below 300 ° C even if locally one of the walls can be brought to a temperature of up to 500 ° (for example by the presence of a grill or sole resistance). It also saves energy by reducing the temperature and cleaning time.
  • the assemblies of the various glass elements between them are glass-glass assemblies (welding or glass-glass embedding), there is no metal element (corner slides by example) to assemble the plates, which allows cleaning with steam or water avoiding any risk of rust.
