Definitions

  • the present invention relates to a hob with a cooking surface made of glass or glass ceramic and at least one atmospheric gas burner and an arrangement for fastening the atmospheric gas burner or burners to the openings for the passage of the burner or burners through the cooking surface made of glass or glass ceramic.
  • the invention relates to a fastening arrangement for protecting the opening edges from mechanical damage and for preventing contamination and damage to the components arranged under the cooking surface due to the penetration of liquid or food through the openings.
  • the atmospheric gas burners were attached using adapter plates, the plates resting on the burner body with at least one tab and being shaped such that they both lie on the inner circumference of a respective cooking surface opening can reach over to the top and bottom of the cooking surface, a seal and / or a heat-insulating material being inserted between the adapter and the sides of the cooking surface.
  • sealing sleeves encompassing the inner circumference of the openings are used (DE-PS 44 42 572 C1). The actual fastening of the burner then takes place via spring elements which press the burner onto the underside of the sealing sleeve.
  • the sealing sleeves are fitted into the opening of the cooking surface by means of an interference fit, soldering, gluing or a bayonet lock.
  • the attachment is carried out by means of a metallic cap which extends over the edge of the respective openings on the glass or glass ceramic plate, an elastic, self-tightening fixing ring formed as a ring disk from a meandering ring band being attached to this cap, which presses with its outer circumference against the metallic cap and its inner circumference rests on the burner body.
  • the invention is therefore based on the object of providing a hob with an arrangement for fastening atmospheric gas burners to the openings of the cooking surfaces made of glass or glass ceramic, in which the number of components required for this is greatly reduced, so that shorter installation times are possible and which allows the burner to be cleaned relatively easily and quickly, if necessary, by removing and reinstalling it.
  • burner bodies are used in which, at a level above the top of the cooking surface, a collar that surrounds the body for support on the top of the cooking surface and below the underside of the cooking surface has suitable holders for non-positively and / or positively receiving spring elements.
  • the brackets can be indentations on the burner body, for example in the form of laterally provided slots or a groove running around the burner body, or molded counter flanges on which the spring elements can rest and, if necessary, snap into place to produce a positive connection.
  • the spring elements are clamped between these brackets on the burner body and the underside of the hob so that they press the burner body downwards so that the circumferential collar formed above the top of the hob is pressed against the top of the hob in the area near the circumference of the hob openings.
  • the burner can be removed quickly and easily using the reverse order of the above steps.
  • different types of spring elements can be used.
  • at least two leaf springs that are opposite one another with respect to the burner body are used.
  • recesses can be used as a holder for the leaf springs, but on the other hand, counter flanges formed on the burner body can also be used.
  • Both the depressions and the counter flanges are advantageously equipped with suitable equipment, e.g. Countersinks, which allow the leaf springs to snap into place for positive locking.
  • suitable equipment e.g. Countersinks, which allow the leaf springs to snap into place for positive locking.
  • a U-shaped leaf spring can also be used.
  • the spring element is a closed tension spring running over the circumference of the burner body.
  • This lies preferably in the form of a meandering ring band which is elastically variable in length over its entire width.
  • the burner must have a largely cylindrical shape in its lower part approximately from the height of the underside of the cooking surface.
  • the burner can also have any other shape in its lower part.
  • the meandering tension spring is pushed from below over the cylindrically shaped lower part of the burner, so that the tension spring widens with its inner diameter and is therefore set too obliquely in the radial direction towards the outer diameter.
  • the spring element is mounted on the largely cylindrical wall of the burner only by frictional connection.
  • the meander spring is able to claw-lock its hardened and sharp-edged lower edge into the burner wall.
  • the underside of the tension spring must then be spaced so far from the underside of the cooktop that the diagonally upward-running meandering ring band of the tension spring can press with its outer diameter against the underside of the cooktop and thereby presses the collar on the top of the cooktop which surrounds the burner body and presses against the top of the cooktop.
  • the tension spring can also snap on its inner diameter to form a positive connection with the burner body in a groove that runs around the cylindrical lower part of the burner or in partially or completely surrounding additional locking grooves (sawtooth) that are integrally formed or recessed on the burner body, which means that the hold supports the burner on the cooking surface and thus ensures greater security against slipping, but such additional, form-fitting holding elements for a meandering tension spring are normally not absolutely necessary.
  • thermostable seal is preferably inserted between the underside of the collar and the surface area of the cooking surface directly adjoining the burner opening, on which the collar comes to rest. This can be in the form of a flat seal or can be designed as an O-ring, in which case a groove for receiving the O-ring is embedded in the underside of the collar.
  • the cooking surface can also be curved upward in the peripheral region of the burner opening, the circumferential collar formed on the burner body then resting on the edge of the cooking surface which is curved upwards.
  • an additional seal between the circumferential collar and the top of the cooking surface can be dispensed with in order to reliably prevent the overflow of cookware from penetrating into the space below the cooking surface.
  • Fig. 1 shows a self-tensioning spring 1, which consists of a meandering ring band 2 which is elastically deformable in the circumferential direction.
  • a collar 5 is formed on the burner 3 at a level above the cooking surface 4, which collar surrounds the burner body and rests on the surface area 7 directly adjoining the opening 6 for the burner.
  • a meandering tension spring 1 is non-positively connected to the burner body by the tension spring being widened with its inner diameter and gripping the burner body with its sharp edge.
  • the diagonal upward meandering ring band of the tension spring 1 then presses with its outer diameter against the cooking surface underside 8 and then holds together with the one sitting on the cooking surface top 7 to the Collar body surrounding collar 5 the burner in its position.
  • a seal 10 is preferably also attached between the collar 5 and the top surface 7 of the cooking surface.
  • the meandering tension spring is positively and positively connected to the burner body in that the meandering tension spring is additionally engaged with its lower edge in a circumferential groove 9 around the cylindrical lower part of the burner, which is spaced so far from the cooking surface underside 8 that the diagonal upward meandering ring band of the tension spring 1 can press with its outer diameter against the cooking surface underside 8.
  • the burner is also attached by force and form, in that the lower edge of the meandering tension spring is also received by latching grooves 20 with a sawtooth profile, which lead wholly or partially around the cylindrical lower part of the burner and either molded onto the burner body or in these are let in.
  • Fig. 3 can be seen from below the tension spring 1, which is drawn onto the cylindrical burner body 11 and locked into the groove 9 for a positive connection.
  • Fig. 5 it can be seen from below how the leaf springs 12 are attached to the burner body 3 in a non-positive and positive manner by means of the depressions 13 and the depressions 14 and how the leaf springs 12 against the ends bent upwards in the direction of the cooking surface 4 Press underside 8 of the hob.
  • a U-shaped leaf spring 15 is used as the spring element, the two legs 16 of which are bent upwards across their width and rest on a counter flange 18 formed on the burner body 3 and each press with their outer edge 19 against the underside 8 of the cooking surface, which creates a positive connection.
  • the cooking surface 4 is flat in the surface area directly adjoining the burner opening 6, so that the collar 5 surrounding the upper part of the burner is advantageously also flat on the underside of the cooking surface 7 on its underside .
  • a thermostable seal 10 is therefore preferably inserted between the collar underside and the surface area 7 of the cooking surface 4 directly adjoining the burner opening 6, on which the collar 5 comes to rest, in order to securely seal the space under the cooking surface 4 from overflowing cookware. This can be dispensed with if an embodiment according to FIG. 7 is used.
  • the cooking surface 4 is curved upward in the peripheral region of the burner opening 6.
  • the circumferential collar 5 formed on the burner body 3 then lies directly on the upper edge of the bulge 21 of the cooking surface 6 located in the peripheral region of the burner opening 6.
  • An additional seal 10 can be omitted in this case.
  • the bulge prevents overcooked cookware from entering.
  • the spring element shown in FIG. 7 on the part of the burner located below the cooking surface 4 corresponds to the embodiment according to FIG. 2a, wherein designs according to FIGS. 2b and c, 4 or 6 are also possible.
