Definitions

  • the invention relates to a gas cooker with a Glass / glass ceramic plate as a cooking surface that has at least one hotplate an open flame gas burner having an opening / bore in assigned to the glass / glass ceramic plate in connection with a pan support is, and the burner ring a mixture of gas and primary air can be supplied is.
  • Cooking appliances with a glass ceramic plate as the cooking surface and cooking zones electrically heated have been on the market for more than two decades. These glass ceramic hobs are valued primarily because of the attractive appearance, flat surface and easy cleaning. Because of of the clear and valued advantages that glass ceramics call Cooking surface material has been around for a few years now tries to use this material with gas cooking appliances or with cooking appliances electrically heated cooking zones combined with so-called gas burners Mixed or duo devices.
  • Typical atmospheric gas burners i.e. such with an open flame, largely through holes in the glass ceramic plate used sealing.
  • the respective cookware is so-called Pot carriers are placed, which in turn stand up on the glass ceramic plate.
  • the conventional atmospheric gas burners have a cylindrical one Gas space which is inserted in the bore of the glass / glass ceramic plate, and which is closed off at the top by a burner wreath from which the flames stepping out.
  • This burner ring is typically above Glass / glass ceramic cooktop, with the flames typically from the inside burn outwards.
  • the object of the invention is based on the above designated cooking device with a glass / glass ceramic plate as the cooking surface, the at least one hotplate with a gas burner with an open flame has an opening in the glass / glass ceramic plate in connection with is assigned to a pot holder, and the burner rim of a mixture Gas and primary air can be supplied, the supply being essentially all for Combustion necessary primary and secondary air from the room below the glass / glass ceramic plate is placed on the flame area of the gas burner, to train this so that with a relatively simple burner construction concentrated heat distribution in the inner burner area is possible.
  • the Gas burner designed as an atmospheric ring burner, below or on the same height of the opening is arranged in the glass / glass ceramic plate and the supply of secondary air to the flame area from the side and / or from below the ring burner.
  • the ring burner arrangement according to the invention differs in its Flame control significantly different from the conventional atmospheric Gas burners installed above the glass / glass ceramic cooktop. At the Ring burner, the flame is directed from the outside inwards.
  • the Flame control causes a more concentrated heat distribution inside Range, which is particularly beneficial for Asian cooking in one Wok is.
  • the Ring burner a very simple and inexpensive burner design what a significant price advantage over the complex conventional wok burners.
  • the glass / glass ceramic plate can be in the area the opening should be flat and bordered with an overflow collar.
  • the edge of the opening must be arched upwards, possibly also with the formation of a lowered gutter, which is a deformed cooktop.
  • the selected air supply which may be supported by a fan can, it is possible to create a pan support in which the Pot support height is less than 25 mm, preferably less than 10 mm; this can significantly increase the risk of the cookware tipping over be reduced.
  • a largely uniform appearance with the cooking surface can be achieved if the base for the cookware is on the pan support is formed by a glass / glass ceramic disc.
  • FIG. Shows a gas burning point of a cooking appliance with a Glass ceramic plate 1 as a cooking surface, which has an opening / hole 2, below that an atmospheric burner, designed as a ring burner 19 symbolically indicated flames 19 a, is included.
  • the ring burner 19 is a conventional pot support 5 with a defined one Pot support height "h" assigned, on which the respective, schematic Cookware 6 shown stands.
  • the figure shows only a single gas burning point of a cooking appliance and it it is understood that the cooking appliance has several such gas burning points can.
  • So-called duo cooking devices can also be provided with a combination of at least one gas burner according to FIGS. and at least one electrically heated cooking zone.
  • the ring burner 19 is via a feed pipe 7 depending on the version of the Brenners a pure gas 8, which later mixed with the so-called primary air is or already a mixture 8 of gas and primary air supplied.
  • This Gas mixture burns in the space 9 between the glass ceramic plate 1 and Bottom of the cookware 6, the exhaust gases 10 between the legs of the Drain the pan holder 5 through to the outside.
  • the distance from the glass ceramic plate 1 to Cookware base can be significantly reduced with great advantage.
  • Today's burner systems have a pot support height "h" between 30 and 60 mm.
  • the pot support height can be "h" less than 15 mm with the same exhaust gas values and the same energy utilization be reduced. This can reduce the risk of the cookware tipping over 6 be significantly reduced.
  • the supply of secondary air 12 can improve the control and Combustion characteristic of the flame still targeted by a fan 13 get supported.
  • This fan 13 can on the one hand actively Support combustion process, but also after switching off the Flame accelerate the cooling process, and with it that Increase the response behavior of the cooking system even further.
  • the edge 1a of the opening 2 in the Glass ceramic plate 1 bent upwards out of the cooking surface. As a result, one can surround the opening with an edge bead provided ring cuff can be dispensed with.
  • the highly formed edge 1a shown can be more clearly under training a ring trough so that the overcooked or Cleaning liquid does not run over the entire cooking surface.
  • the ring burner can also be the same Height as the hole / opening 2 of the cooking surface.
  • the flames 19a of the ring burner 19 burn in a circle inwards directed and / or directed vertically upwards and / or in a remaining Angle in between.
  • the secondary air 12 is from below the cooking surface 1 to the flames 19 a introduced. On the one hand, this can be done from the outside, i.e. directly below the Glass ceramic plate underside. On the other hand, it is also conceivable that the secondary air 12 is supplied from within the ring burner 19.
  • Collection tray 20 can be placed in the overcooking or cleaning agent can record, which should possibly overcome the curved edge 1 a.
