The present invention further relates to a gas stove having at least one gas hob according to the manner set out above.

State of the art

In order to prevent flames of the gas burner damage the bearing surface by overheating, gas burners usually have a metal, in particular sheet metal, formed heat protection device, such as a torch head encircling heat protection cap on. This heat protection device is glued according to the prior art by means of silicone adhesive on the hob plate.

Due to the technical advancement of gas burners, these provide an ever greater heating power, which is why an ever higher nominal heat input takes place on the heat protection device. Developing new silicone adhesives to withstand this higher heat input is currently causing technical difficulties. Therefore, it is desirable to develop a mounting option for the thermal protection device, can be dispensed with the silicone adhesive.

From the prior art it is known to attach the nozzle holder or the base of the gas burner mechanically to the hob plate. For example, according to the publication US Pat. No. 6,173,708 B1 the base by means of a ring encircling the base clamped to the underside of the hob plate. By means of a plug connection, the burner head can then be fixed to the base. In this known gas hob, the supporting surface of the hob is sandwiched between the burner base and the burner head. A direct attachment of the burner head to the supporting surface is not provided.

Also in the case of the publication US Pat. No. 6,817,355 B1 known gas hob, the bearing surface of the hob is sandwiched between the burner base and the burner head, the burner head is seated on the burner base and clamped by means of a Klickbefestigung the burner base.

From the pamphlets DE 603 12 832 T2 . DE 198 19 732 C1 and EP 0 964 203 A1 It is known to attach the burner base by means of a spring, for example by means of a plate spring, on the underside of the hob plate. An attachment of a heat protection device to the hob plate is not provided. Instead, the document teaches DE 603 12 832 T2 To arrange the heat protection device at a distance from the hob plate so that air can flow between the heat protection device and the hob plate for cooling.

• eine Feder, die den Brennerkörper von unten gegen die tragende Fläche des Kochfelds drückt.

A gas hob according to the type set forth is from the document DE 197 42 792 C1 known. This gas hob has

• a designed as a heat protection device, the burner body rotating and connected by screws to the burner body collar which rests under pressure on the supporting surface of the hob, and
• a spring that presses the burner body from below against the supporting surface of the hob.

A disadvantage of the aforementioned gas hob that the collar is attached only to the burner body, so only indirectly, on the supporting surface and that the spring for fastening the burner body underflows the entire bottom of the burner body and thus occupies a relatively large amount of space in the gas hob.

DESCRIPTION OF THE INVENTION: Problem, Solution, Advantages

Based on the disadvantages and shortcomings set out above and in appreciation of the outlined prior art, 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 heat protection device very close to the supporting surface of the Gas hob is applied. The heat protection device should be fastened without the use of adhesive in a simple and space-saving manner to the supporting surface.

This object is achieved by a gas hob with the features specified in claim 1 and by a gas stove with the features specified in claim 15. Advantageous embodiments and expedient developments of the present invention are characterized in the subclaims.

Consequently, the present invention is based on the fact that the heat protection device is mechanically or detachably fastened, for example clamped, mechanically via at least one fixing element, for example via at least one clamp, to the supporting surface of the gas hob. The fixing element is in direct contact with the thermal protection device and / or is connected directly to the thermal protection device. This has the advantage that the heat protection device is fixed directly to the supporting surface and thus rests very close to the supporting surface. Therefore, neither air nor water nor dirt can penetrate at the contact surface between the heat protection device and the supporting surface. This has the advantage that the ignition behavior of the gas burner is significantly improved and the flame burns much more stable compared to the prior art.

In order to seal the contact surface between the heat protection device and the supporting surface particularly well, is between the heat protection device and the Heat protection device facing top of the bearing surface preferably at least one, in particular water and / or air impermeable, sealing element arranged.

The present invention has the advantage that, in comparison with the prior art, in which the heat protection device is glued to the supporting surface, in the manufacture of the gas hob according to the invention eliminates the steps of gluing and drying of the adhesive. Due to the elimination of the adhesive, no corrosive vapors caused by adhesives occur in the manufacture of the gas hob according to the invention, in contrast to the prior art.

The attachment of the thermal protection device is advantageously a releasable attachment. Due to the direct contact and / or the direct connection of the fixing with the heat protection device needs in contrast to the prior art, in which the spring underneath the bottom of the gas burner, to replace the fixing element not the nozzle holder removed. Thus, the fixing can be replaced comparatively faster and easier.

Advantageously, the fixing element defines the position of the gas burner, in particular of the burner head designed to provide the flame. For example, the fixing element defines the distance between the burner head and the nozzle holder designed to support at least one burner nozzle and / or the distance between the flame and at least one thermocouple arranged below the supporting surface and for monitoring the flame, in particular for detecting the presence of the flame ,

The fixing element may be integrally formed with the heat protection device, for example at least one foot or web that clamps the heat protection device to the supporting surface. In this case, the foot or web preferably extends through a recess of the bearing surface and firmly clamps the heat protection device to the supporting surface of the gas hob.

• Düsenhalterung im Wesentlichen unterhalb der Wärmeschutzvorrichtung und unterhalb der tragenden Fläche, genauer gesagt unterhalb der von der Wärmeschutzvorrichtung abgewandten Unterseite der tragenden Fläche, in einer Kochmulde angeordnet ist und
• Brennerkopf im Wesentlichen oberhalb der tragenden Fläche, genauer gesagt oberhalb der von der Kochmulde abgewandten Oberseite der tragenden Fläche, angeordnet ist.

According to a preferred embodiment of the present invention extends through the recess of the supporting surface next to the fixing and the gas burner whose

• Nozzle holder substantially below the heat protection device and below the supporting surface, more precisely below the underside of the supporting surface facing away from the heat protection device, is arranged in a cooktop and
• Burner head is disposed substantially above the supporting surface, more precisely above the top of the supporting surface facing away from the cooktop.

Alternatively or in addition to the integrally formed with the heat protection device fixing the hob can have at least one (further) fixing, which is connected by means of at least one connecting element, for example by means of at least one screw and / or by means of at least one connector with the heat protection device.

• zumindest bereichsweise an der von der Wärmeschutzvorrichtung abgewandten Unterseite der tragenden Fläche und
• zumindest bereichsweise zwischen der Wärmeschutzvorrichtung und der Düsenhalterung

angeordnet ist.Regardless of or in connection herewith, as an alternative or in addition to the clamping element extending through the recess of the bearing surface, at least one (further) substantially horizontally extending fixing element may be provided

• at least partially on the side facing away from the heat protection device underside of the supporting surface and
• at least partially between the heat protection device and the nozzle holder

is arranged.

In this case, the essentially horizontally extending clamping element with the extending through the recess of the supporting surface clamping element advantageously cooperates such that on the heat protection device downwardly directed to the cooking force, in particular that the heat protection device on the supporting surface and on the nozzle holder is pressed.

The region of the substantially horizontally extending clamping element arranged between the heat protection device and the nozzle holder is preferably adapted to the geometry of the nozzle holder, in particular substantially congruently onto the area of the nozzle holder facing the heat protection device.

In order to reliably prevent direct contact of the flame with the supporting surface, in an advantageous embodiment of the present invention, the thermal protection device circumscribes the burner head. Furthermore, the essentially horizontally extending clamping element can at least partially circulate the gas burner, in particular the burner nozzle and / or the nozzle holder. This has the advantage that the region of the nozzle holder facing the heat protection device is covered and protected by the essentially horizontally extending clamping element.

The fixing element is advantageously formed of metal, for example of sheet metal. This offers the advantage that the fixing can withstand even a very high heat input. But it is also possible to manufacture the fixing of heat-resistant plastic or other material.

Best way to carry out the invention

In order to avoid superfluous repetitions, the following explanations concerning the embodiments, features and advantages of the present invention (unless stated otherwise) refer to both the Fig. 1 illustrated first embodiment of the gas hob 100 with a first embodiment of a fixing element 40 as well as on in Fig. 2 and 3 illustrated second embodiment of the gas hob 100 'with two further embodiments of a fixing element 40' and 40 "and on the in Fig. 4 and 5 illustrated third embodiment of the gas hob 100 "with a fourth embodiment of a fixing element 40"'.

For the sake of clarity is in the FIGS. 1 to 5 in each case only one gas hob with a supporting surface, namely a cooktop plate 50, a gas burner and a heat protection device, namely a thermal protection cap 10 or 10 'or 10 "surrounding the head 20 of the gas burner. or 100 "several, for example four or six, have gas cooking.

For all three in the FIGS. 1 to 5 illustrated embodiments, the heat protection cap 10 and 10 'and 10 "in comparison to the prior art, a new design.

This is how the in FIG. 1 illustrated first embodiment of a heat protection cap 10 at least two integrally formed with the heat protection cap 10 fixing elements for securing the heat protection cap 10 to the supporting surface 50, namely four clamping feet 40. By means of these clamping feet 40, the heat protection cap 10 to the hob plate 50, more precisely to a trained for receiving the gas burner recess of the hob plate 50, klippbar. The clamping feet 40 extend through the recess of the hob plate 50 and clamp the heat protection cap 10 on the hob plate 50 from above and from below, so on the heat shield 10 facing top 54 of the hob plate 50 and on the side facing away from the heat shield 10 bottom 56 of Hob 50, fixed. The clamp feet 40 of in FIG. 1 shown heat protection cap 10 are particularly stable due to their wedge-like shape, in particular they hold in the vertical direction acting tensile or compressive loads particularly well withstand.

In the recess of the hob plate 50, the clamping feet 40 are laterally on the one hand on the hob plate 50 and on the other hand on the gas burner. Thus, the clamping feet 40 fix the heat protection cap 10 in the horizontal direction.

An exact positioning of the thermal protection cap 10 or 10 'or 10 "is particularly important since the heat protection cap 10 or 10' or 10" defines the position of the gas burner by rotating the burner head 20 and on the nozzle holder 30 holding the burner nozzle 32 of the gas burner rests. The in the FIGS. 1 to 3 illustrated two embodiments of a gas hob 100 or 100 'have the advantage that the fixing elements 40 or 40' and 40 "can not be solved by the user of the gas hob 100 or 100 ', since the fixing elements 40 and 40' and 40" are each covered by the heat protection cap 10 and 10 '. Thus, it is reliably prevented that the position of the gas burner is inadvertently changed by loosening the thermal protection cap 10 or 10 '.

This in FIG. 2 illustrated second embodiment of a heat protection cap 10 'has four substantially rectangular formed, extending through the recess of the cooktop panel 50 clamping feet 40'. An advantage of these rectangular clamping feet 40 'is that they take up very little space in the hob arranged below the hob plate 50.

To attach the heat protection cap 10 'has the in FIG. 2 illustrated second embodiment of a gas hob 100 'further a cooperating with the clamping feet 40' further fixing element, namely a gas burner, in particular the burner nozzle 32 and / or the nozzle holder 30 of the gas burner, encircling clamping ring 40 "This clamping ring 40" is partially below the Hob plate 50 and partially disposed between the heat shield 10 'and the nozzle holder 30. This has the advantage that an example screwed connection 70 between the heat protection cap 10 'and the nozzle holder 30 by the clamping ring 40 "can be protected.

Furthermore, by means of the clamping ring 40 ", a connection between at least one gas tube designed for providing gas or gas mixture, a so-called gas tube, and the nozzle holder 30 can also be protected, which is particularly advantageous if the gas tube and the nozzle holder 30 are made of different materials are formed, for example, when the gas pipe is formed substantially of aluminum and the nozzle holder substantially of metal, such as sheet metal or cast iron.

The set of clamping feet 40 'and clamping ring 40 "is positioned in the gas hob 100' by means of pressing and turning, whereby the clamping ring 40" for receiving the clamping feet 40 'has a respective recess 42. The regions 44 of the clamping ring 40 "surrounding the respective recess 42 are designed so that they can be pressed onto the clamping feet 40 ', in particular pressed against the clamping feet 40' Clamp feet then arranged in the recesses 42. The turning is in FIG. 2 represented by curved arrows.

The region of the clamping ring 40 "which is in contact with the nozzle holder 30 is adapted to the geometry of the nozzle holder 30 and can thus be placed congruently on the nozzle holder 30. The clamping ring 40" is therefore arranged in the cooktop in a very space-saving manner.

FIG. 3 shows a schematic representation of a detailed view of the clamping ring 40 ".

At the in FIG. 4 The exemplary embodiment of a gas hob 100 "fixes the heat protection device 10" to the hob plate 50 by means of a fourth exemplary embodiment of a fixing element 40 "." This fixing element 40 "'is a clamping ring 40"' surrounding the gas burner, which extends below the hob plate 50 and partially between the heat protection cap 10 'and the nozzle holder 30. A detail view of the clamping ring 40 "' is in FIG. 5 shown in schematic representation.

The clamping ring 40 "'is screwed by means of screws 70 with the heat protection cap 10" and the nozzle holder 30. These screws 70 thus connect the heat protection device 10 ", the clamping ring 40" 'and the nozzle holder 30 and thus define the position of the gas burner, in particular the nozzle holder 30.

Also in the in the FIGS. 1 to 3 illustrated embodiments, the heat protection cap 10 and 10 'by means of screws 70 connected to the nozzle holder 30. The in the FIGS. 1 to 3 illustrated heat protection caps 10 and 10 'are thus particularly firmly connected to the gas burner, since they are fixed on the one hand by means of fixing elements 40 and 40' and 40 "on the gas burner and are additionally bolted thereto still with the nozzle holder 30. A close connection between the Heat shield and the gas burner is particularly advantageous because the position of the heat protection cap defines the position of the gas burner.

For receiving the screws 70, the clamping rings 40 "(see. FIG. 3 ) or 40 "'(cf. FIG. 5 ) Recesses 72 (see. FIG. 3 ) or 72 '(see. FIG. 5 ) on.

In order to avoid that dirt or water penetrates into the cooktop, seals 60 are respectively arranged between the heat protection cap 10 or 10 'or 10 "and the cooktop panel 50.

In the FIGS. 1 to 5 Thus, three exemplary embodiments for a mechanical fastening of the heat protection cap 10 or 10 'or 10 "are shown, wherein by means of this mechanical fastening the position of the heat protection cap 10 or 10' or 10" and the position of the burner nozzle 32 and the burner nozzle holder 30th , in particular the distance between a flame provided by the gas burner and at least one thermocouple arranged below the supporting surface 50 and designed to monitor the flame, in particular to detect the presence of the flame.

By means of the above-described mechanical fasteners in which the fixing element 40 or 40 'and 40 "or 40"' directly with the heat protection device 10 or 10 'or 10 "in contact and / or is connected directly to this, the Heat protection cap 10 or 10 'or 10 "fixed particularly close to the hob plate 50, which has an advantageous effect on the ignition behavior of the gas burner. Due to the direct attachment of the heat protection cap 10 or 10 'or 10 "to the hob plate 50, neither dirt nor water nor air can penetrate the contact surface between the heat protection cap 10 or 10' or 10" and the hob plate 50. This also causes the flame of the gas burner burns much more stable compared to the prior art.
