Definitions
- the present invention relates to a burner cover for a gas burner, a gas burner and a gas hob with at least one gas burner.
- the gas burner has a burner head, the top of which is covered with the burner cover.
- a cooking hob of the generic type is known from DE 198 13 691.
- the hob has at least one gas burner and a hob plate made of glass ceramic surrounding this gas burner. Components or functional parts of the components of the gas burner are arranged in the region of an opening assigned to the respective burner in the hob plate below, above or in the main plane of the hob plate, the gas burner being carried by the hob plate.
- the gas burner has a burner cover that covers an upper side of a mixing chamber. Gas holes or slots are integrated in the burner cap. In order to support the ease of cleaning and the overall aesthetics, the burner cover is advantageously formed from the hob plate material glass ceramic.
- the gas burner has an upper burner ring which is provided with gas outlet openings which generate the main and holding flame and are supplied by an upper gas-air mixture supply chamber.
- the top of the gas burner has a round cover plate, the underside of which has a protruding centering edge on the outer edge, which engages in an all-round recess provided on the upper burner ring and thus is centered centrally.
- the object of the present invention is to provide a burner cover for a gas burner, a gas burner and a gas hob with a gas burner, which is easy to clean.
- the object is achieved by the gas burner according to claim 1, the gas hob according to claim 8 and the burner cover according to claim 14.
- the burner cover is in two parts with a lower cover part, which lies directly on the burner head, and with one on top arranged upper lid part formed from a glass ceramic material. Since the upper part of the cover is made of a glass ceramic material, the top of the gas burner is easy to clean. At the same time, the glass ceramic material of the upper cover part favors the appearance of the burner.
- the two-part design of the burner cover makes it possible to continue to use the functional other cover part in the event of damage to one of the cover parts, for example the damage-prone upper glass ceramic cover, so that only the damaged cover part has to be replaced.
- the lower cover part can be made of a metal. Compared to glass ceramics, metal is easy and inexpensive to machine. Functional elements of the gas burner, for example gas bores or slots, are therefore to be formed in a simple manner in the lower cover part. At the same time, the top cover part ensures easy cleaning of the top of the gas burner and an advantageous appearance.
- the upper cover part can be detachably arranged on the lower cover part.
- the upper lid part is particularly susceptible to contamination, for example due to cooking liquid dripping from a pan support.
- the upper cover part is dome-shaped. This results in smooth transitions in the edge area of the upper cover part, which increases the ease of cleaning the upper cover part. In addition, drainage of, for example, cooking liquid from the upper cover part is promoted.
- a heat-insulating air gap can advantageously be provided between the upper cover part and the lower cover part. As a result, the temperature of the upper cover part is kept below the temperature of the lower cover part during burner operation, as a result of which the glass ceramic material of the upper cover part is less stressed.
- the upper cover part has a centering edge which interacts with a corresponding ring structure of the lower cover part. As a result, the upper cover part can be placed in the correct position again on the lower cover part, in particular after cleaning separately from the gas burner.
- the game is preferably 0.5 to 1 mm.
- tensions in the upper cover part due to different material expansions can be prevented by the game.
- the gas burner is arranged in an assembly opening of the hob plate, which is made of a glass ceramic material.
- the hob plate is designed in such a way that an opening edge of an assembly opening of the hob plate is shaped in a tulip shape upwards. This prevents the food or cleaning liquid from reaching the top of the hob plate through the mounting opening into an interior of the gas hob.
- the upper cover part and the hob plate form a continuous shape in such a way that the edges of the hob plate and the upper cover part to be facing one another have the same slopes.
- the appearance of the gas hob is designed to be particularly appealing.
- a smooth transition between the hob plate and the upper lid part is achieved, which increases the ease of cleaning the gas hob. It is particularly preferred if the outer diameter of the upper cover part is greater than or equal to the outer diameter of the raised opening edge of the assembly opening. Cooking liquid dripping from the top lid part thus reaches the hob plate without contaminating the burner.
- the material thicknesses of the upper cover part and the hob plate can advantageously be dimensioned essentially the same size.
- Figure 1 shows a section of a gas hob in a
- Figure 2 is an exploded view of the gas hob
- Figure 3 shows a detail of a perspective view
- FIG. 1 A section of a gas hob 1 is shown in FIG.
- the gas hob 1 has a base pan 3 with raised side walls 5 (FIG. 2). On the upper edges of the side walls 5 there is a hob plate 7 made of a glass ceramic material.
- an assembly opening 9 for a gas burner 11 is provided in the hob plate 7.
- An opening edge 13 of the mounting opening 9 is formed tulip-shaped upward from a plane of the hob plate 7.
- the opening edge 13 rises at a first gradient angle ⁇ 1 , which is approximately 70 °.
- the gas burner 11 has a burner angle 15 which is arranged in a bowl interior 17 between the floor pan 3 and the hob plate 7.
- the burner angle 15 is connected to a gas feed line, not shown, and is provided with a gas nozzle 19.
- the burner angle 15 is fastened to the floor pan 3 by means of a fixing arrangement 21.
- a gas stream I emerging from the gas nozzle 19 during burner operation is fed together with primary air II sucked in at the side into a mixing chamber 30 of the gas burner 11 described later.
- a mounting plate 23 is attached to an upper end face 22 of the burner bracket 15.
- the mounting plate 23 carries a spark plug 25 and a circumferential seal 27.
- the seal 27 is arranged according to the figure 1 between the mounting plate 23 and an underside of the hob plate 7.
- a burner head 29 is located on the upper end face 22 of the burner angle 15.
- the burner head 29 is located on an inner wall of the upwardly shaped opening edge 13 via a seal 31.
- the burner head 29 has a gas / air mixture channel 33 formed in the center through which the gas stream mixed with primary air II flows into the mixing chamber 30.
- a burner cover 35 is seated on the burner head 29.
- the burner cover 35 is formed in two parts by a lower cover part 37 and an upper cover part 39 arranged thereon from a glass ceramic material.
- the lower cover part 37 has a circumferential centering projection 41 on its underside. This is arranged for centering the burner cover 35 within a raised peripheral wall 43 of the burner head.
- the lower cover part 37 lies on an upper end face of the raised peripheral wall 43.
- the lower cover part 37 has gas passage openings 45 formed on the circumference, through which the gas mixture exits to form a flame.
- the lower cover part 37 has supply channels 47.
- the supply channels 47 connect the mixing chamber 30 to an annular groove 49 running on the outer circumference of the cover part 37.
- the ring groove 49 prevents the flames from being torn off during burner operation. The burner 11 is therefore protected against a flashback.
- an ignition chamber 52 (on the right in FIG. 1) is formed in the lower cover part 37, into which the spark plug 25 projects in order to ignite the gas mixture emerging from the mixing chamber 30.
- the lower cover part 37 is formed with a step-shaped ring structure 51 on its upper side.
- the ring structure 51 interacts with a centering edge 53 of the upper cover part 39, as a result of which the upper cover part 39 is centered.
- the outer diameter of the centering edge 53 and the outer diameter of the lower cover part 37 are the same size according to FIG. 1. As can further be seen from FIG. 1, the material thicknesses of the upper cover part 39 and the hob plate 7 are dimensioned essentially the same size. The outer diameter of the upper cover part 39 is also equal to the outer diameter of the upwardly shaped opening edge 13.
- the centering edge 53 of the upper cover part 39 rises at a second pitch angle ⁇ 2 , which is approximately 70 °.
- the pitch angles c ⁇ and ⁇ 2 are therefore designed to be essentially the same size, so that the upper cover part 39 and the hob plate 7 form a continuous shape.
- Cooking liquid flowing out of the upper cover part 39 consequently drips over the centering edge 53 directly onto the top of the hob plate 7 without the liquid being able to collect in the lower cover part 37 or in the burner head 29.
- the gas passage openings 45 and the ignition chamber 52 in the lower cover part 37 are therefore protected against flowing liquid.
- FIG. 1 further shows that the upper side of the lower cover part 39 is essentially flat, while the upper cover part 39 is dome-shaped. Due to the spherical shape of the upper cover part 39, on the one hand liquid can flow better from the upper cover part 39. On the other hand, a heat insulating air gap 55 is provided between the upper and lower lid parts.
- the burner angle 15 is first placed on the fixing pins 57 of the fixing arrangement 21 and then the mounting plate 23 via an annular one Tension spring 59 fastened in the area of the upper end face 22 of the burner bracket 15.
- the burner head 29 is placed on the mounting plate 23 with the interposition of the seal 27.
- the hob plate 7 is placed with the interposition of the seal 31 on the upper edges of the side walls 5, whereby the interior 17 of the bowl is closed.
- the lower cover part 37 of the burner cover 35 is then centered on the burner head 29.
- the upper cover part 39 is placed on the lower cover part 37.
- FIG. 3 shows an upper side of the assembled gas hob in an enlarged perspective view.
- the arrows F indicate a cooking liquid flowing off the top of the lid part 39, which has dripped from a pan support, not shown. Accordingly, the cooking liquid flows from the spherical end face of the upper lid part 39 to its centering edge 53 and drips from the centering edge 53 of the lid part 39 onto the top of the hob plate 7 without contaminating the burner 11.
