Definitions

  • the present invention relates to a cooking appliance door with a front part, which has a door handle is assigned, and a back part, between which a thermally insulating functional part with Distance to the front part is arranged, as well as one equipped with such a door Cooking appliance.
  • Such a cooking device door is known from US-A-4,084,571, wherein between the multi-part and back part designed as a trough-shaped door bottom and the front part designed as a front frame with an inserted pane in the area a window pack held on the door base between the window pack or a heat shield is provided for the door base and the front frame or the front glass pane is.
  • the heat shield has numerous openings to improve transparency and is highly reflective on the side facing the cooking space. On the cooking space the heat shield is black.
  • an oven door is known from the publication DE 43 04 485 A1, the metallic door floor encloses a pane facing the oven muffle. On the door floor a windscreen is attached. In the area opposite the metallic door floor is the front glass pane on the inside facing the cooking space partially provided with a reflection layer, for example with a surface polished Aluminum foil.
  • the equipment room is at least partially surrounded by at least one multi-layer layer of air chambers enclosing airtight foils, preferably made of aluminum foil material consist.
  • the object of the present invention is to provide a cooking appliance door which Keeps heat loss from the cooking space as low as possible.
  • the functional part facing the front part Side has a surface whose emission factor is less than 0.3, in particular is less than 0.1. Since the emission factors of the surfaces facing the front part the back, which typically consist of glass, enamel or an enamel mist, for example are 0.8 to 0.95, the heat radiation towards the front part is according to the invention significantly reduced in the area of the functional part.
  • the areal extent of the functional part can be limited to the most critical areas of the door or over a large area, for example, be frame-shaped.
  • a further reduction in heat transport from the cooking space to the front part is according to the invention thereby achieved that the functional part at the same time as a thermal insulator is trained. Preventing undesired heat conduction is particularly good and the heat radiation can be realized in that the functional part by a multilayer insulating film, in particular made of aluminum, is formed the integrated air chambers having.
  • the insulating part could also be used as a ceramic or plastic part can be realized, at least on the front part facing Surface with aluminum or a similarly low heat radiating surface is provided.
  • the functional part advantageously lies directly on the back part. This is avoided that an air flow between the functional part and the back part take place can, whereby heat could be removed by air convection.
  • the door assembly is particularly simple when the functional part is through a holding part is clamped to the back part. It should be noted that the heat conduction from the functional part to the holding part is advantageously kept as low as possible. The thermal insulation properties of the door will be further improved if that Functional part and the holding plate together with the back part a heat insulating Limit or close the air chamber.
  • the structure of the door is further simplified by that the holding plate is frame-shaped and one between the front part and moves the inner disc pack held on the back.
  • FIG described cooking appliance door An exemplary embodiment of FIG described cooking appliance door according to the invention or a correspondingly equipped cooking appliance.
  • An oven has a cuboid-shaped metallic oven muffle 1 which is open at the front. This is essentially thermally insulated on all sides in a manner known per se. Furthermore, the oven muffle 1 are known heating elements for heating the Assigned to the cooking space (not shown).
  • the oven muffle 1 is by a front Oven door 3 lockable. 1 is exemplary without limitation of the invention a door 3 for an oven with pyrolysis operation shown. This has one metallic door floor 5, which is trough-shaped and the cooking chamber facing side is enamelled and its side facing away from the cooking space is at least provided with an enamel mist. Lies in the closed state between the back of the door base 5 and the flange of the oven muffle 1 a Cooking chamber opening essentially frame-like moving oven seal 7.
  • a bow-shaped door handle 11 is fastened in a central one
  • the opening in the door base 5 is a known disk package 13 supported.
  • a package holder 15 holds the two disks and is on Door floor with an intermediate seal 17 attached.
  • a frame-shaped shielding plate 19 can be formed both substantially flat and profiled according to FIG. 1.
  • the outer edge region of the shielding plate 19 is at least in its upper area angled. The shield plate presses at this angle 19 a strip-shaped design with essentially linear contact Aluminum foil package 23 to the surface of the front panel 9 facing Door panel 5.
  • the shield plate 19 forms together with the inside of the Door bottom 5 or the window of the window package 13 and in particular in the area the aluminum foil package 23 together with this one the thermal Insulation properties of the furnace door 3 further improving air chamber 21.
  • the aluminum foil package 23 consists of two outer cover foils 31 and a plurality of inner foils 33 which are connected to one another on all sides at the edge. This include numerous air cushions 35 airtight as described below.
  • To are the films in a regular pattern with cup-shaped as embossing points Provide spacers that are mutually supportive, these multi-profiled foils are assigned to one another or placed one on top of the other are that the spacer elements meet each other for support.
  • the Spacers preferably have circular depressions on the support surfaces, in which the corresponding spacer elements with their flat support surfaces immerse and are held positively.
