Description

Gas burner with removable burner lid The invention relates on a gas burner. with removable burner cover and a protective cover except for high quality, resistant, rustproof and non-corrosive, poorly thermally conductive material.

It. is known to have a cast iron single gas burner for kitchens in the - 'To be laid out with sheet brass on the inside. Besides-was already at a tube burner a protective layer for permanent combustion between - "the pipe and the combustion chamber made of chrome-nickel steel. The use of a chromium-nickel alloy has also been used suggested as a material for B_ renne_r_ nozzles.

In contrast, the invention consists in that in a gas burner the described. Type of protective coating only on the edge of the burner head or Burner cover or both is attached and from a crimped around this edge Sheet metal ring. Those defining the gas outlet cross-section are also useful Projections on the burner head. or cover provided with the protective coating.

The low thermal conductivity of the protective material makes it difficult. Heat flow from the gas exit points to the other burner and stove parts. The transition from the protective material to the burner material is another Difficulty for the heat flow conditional. In order to throttle him even more, you can save the protective coating a ring or the like made of a poorly thermally conductive material be arranged so that it has a partial cross-section perpendicular to the direction of heat discharge of the burner head.

The formation of a burner according to the invention results in the relatively costly material of the protective coating the advantage with the least possible Costs the burner at the most vulnerable points against mechanical and thermal To protect impacts with security. It also increases the spread of heat prevented by the burner material at their point of origin, so that heat losses due to radiation are avoided - and also heat transfer to the other accessories, e.g. B. to the Hahhküken; is prevented.

The invention is illustrated, for example, in the drawing.

Fig. I shows a burner cover a, which is made in a known manner from cast iron, Brass, light metal or the like. Is and its edge with a ring b from the described Material, e.g. B. chromium-nickel alloy, um-, flanged is.-Fig. 2 is also one Burner cover cal. With the sheet metal ring b1 again, - which also corresponds to the gas outlet cross-section producing approaches cl covered.

The burner can also be attached to the burner cover or with it according to Fig. 3 with a. such sheet metal rings covering the approaches f provided be.

In Fig.4 there is a second ring for 'throttling the' heat flow h made of poorly thermally conductive material except for the sheet metal ring g provided by this sheet metal ring is held and causes a heat transfer substantially can only be done at the fastening points of the sheet metal ring g.

Claims (3)

PATENT CLAIMS: i. Gas burner with removable burner cover and one Protective cover made of high-quality, durable, rustproof and non-corrosive, poorly thermally conductive material, characterized in that the sheet metal ring trained protective coating around, the edge of the burner head or burner cover or both are crimped. 2. Gas burner according to claim i, characterized in that also the projections on the burner head that define the gas outlet cross-section -lids are provided with the protective coating. 3. Gas burner according to claim i or 2, characterized in that in addition to the protective coating, a ring or the like. Bad thermally conductive material is arranged such that it is perpendicular to the direction of the Heat discharge fills a partial cross-section of the burner head.
