Definitions

  • the present invention further relates to a gas stove, comprising at least one gas hob according to the kind set forth above.
  • the nozzle holder of the gas burner according to the prior art is usually glued to the covering surface by means of adhesive, preferably by means of silicone adhesive.
  • adhesive preferably by means of silicone adhesive.
  • the bond withstands only a relatively limited nominal heat input.
  • the gas burner is not glued to the cover but is instead using Coil springs pressed against a arranged below the cover surface positioning. Furthermore, in the document DE 103 27 044 A1 discloses supporting a gas burner via coil springs on the one hand on the burner housing and on the other hand on the glass ceramic plate. The known gas burners are each mounted on the coil springs. This allows a horizontal play of the gas burner against the spring force of the coil springs. In particular, in assembly tolerances of the gas hob and occurring in the gas hob pressure fluctuations, which can be caused for example by gas explosions, a flexible storage of the gas burner is advantageous. A disadvantage of the aforementioned gas hobs that the respective gas burners are held only by the force acting against the cover surface contact pressure of the coil springs in position.
  • a disadvantage of these known constructions is that for the storage of the gas burner on the one hand the gas burner must be attached to the upper metal plate and on the other hand, the upper metal plate must be attached to the lower metal plate and the lower metal plate must be attached to the housing of the gas hob. For this purpose, three separate fasteners are required.
  • a gas hob according to the type set forth is from the document EP 0 905 452 B1 known.
  • the gas burner is screwed to the cover surface.
  • the gas burner is mounted on a traverse, which is mounted on the bottom surface of the burner housing via coil springs.
  • the location of this known gas burner is defined solely by the screw on the cover surface. The user of the gas hob dissolves them from the outside accessible screws, so the gas burner slips and must be repositioned.
  • the present invention has the object, a gas hob of the type mentioned and a gas stove of the type mentioned in such a way that the nozzle holder flexible against assembly tolerances of the gas hob as well as , For example, caused by gas explosions of the gas burner, pressure fluctuations and is still reliable in a simple way in the gas hob can be fastened.
  • the present invention is based on the fact that the gas burner on the one hand on the cover surface and on the other hand by means of at least one nozzle holder on the housing, in particular on the bottom surface, mechanically fixed.
  • the attachment to the housing is an elastic attachment.
  • the gas burner preferably the nozzle holder of the gas burner, according to the invention is attached to both the cover surface and the housing of the gas hob, the gas burner can not be solved by the user and accidentally slipped. Should the fastening of the gas burner to the cover surface be loosened or loosened, the position of the gas burner nevertheless remains stable due to its attachment according to the invention to the housing.
  • the gas burner Due to the elastic attachment of the nozzle holder on the housing, the gas burner can be easily mounted and accurately positioned even with mounting tolerances of the gas hob.
  • the gas burner is insensitive to pressure fluctuations occurring in the gas hob due to the elastic attachment of the nozzle holder on the housing.
  • Another advantage of the elastic attachment of the nozzle holder to the housing is that forces acting on the gas burner are not transmitted as leverage forces on the covering surface formed of fragile material.
  • Another advantage of the present invention is that the mechanical attachment of the gas burner or nozzle holder is not damaged even with a high nominal heat input.
  • the nozzle holder Since the fixing element fixes the nozzle holder on the housing, the nozzle holder is thus in direct contact with the housing, in particular with the bottom surface.
  • the nozzle holder for attaching the nozzle holder to the housing significantly fewer components are required than in the prior art, wherein the nozzle holder is attached to a first metal plate and this first metal plate is attached to another metal plate attached to the housing. The reduction of components saves assembly time and material costs.
  • the fixing element fixes the nozzle holder detachably on the housing, for example by means of at least one screw or plug connection.
  • the first connecting element has at least one thread with which the main body of the further connecting element can be screwed.
  • the elastic element is preferably at least one compression spring, which causes a pressing force of the nozzle holder against the cover surface.
  • Particularly advantageous is the use of a wound around its inner diameter coil spring as an elastic element.
  • a significant advantage of the coil spring is its constant spring stiffness or spring stiffness, whereby a consistently defined contact pressure of the nozzle holder is effected against the cover surface.
  • the elastic element may, for example, be at least one spiral spring, at least one leaf spring or at least one elastically deformable rubber or plastic element.
  • the fixing element may be a separate component or may be formed integrally with the nozzle holder.
  • the region of the nozzle holder attached to the housing surrounds the burner nozzle at least in regions.
  • the region of the nozzle holder fastened to the housing can be arranged on at least two opposing locations adjacent to the burner nozzle.
  • the region of the nozzle holder attached to the housing can rotate around the burner nozzle.
  • at least two to the burner nozzle at least one fixing element, which fixes the nozzle holder to the housing, is arranged in adjacent regions.
