    image3 GAS BURNER, GAS COOKING POINT, GAS KITCHEN, AND PROCEDURE FOR CHANGING THE FUEL GAS OF A GAS BURNER DESCRIPTION
    The present invention refers to a gas burner, a gas cooking point, a gas cooker, and a method for changing the combustible gas of a gas burner.
    A gas burner has a mixing chamber or mixing tube in which a gas injector injects combustible gas. The mixing tube acts as a Venturi tube, so that primary air is sucked into the mixing chamber, flowing laterally next to the gas injector. To use different combustible gases, the gas injector is replaceable, without the mixing chamber being modified.
    Given this background, the present invention solves the technical problem of providing an improved gas burner.
    Therefore, a gas burner for a gas cooker is proposed, with a mixing tube for mixing combustible gas with primary air, with a gas injector that is configured to inject the combustible gas into the mixing tube, and with an insert Changeable and introducible in the mixing tube to modify its geometry.
    When the insert is changeable, the geometry of the mixing tube can be modified if a change of fuel gas is going to occur. In this way, pre-mixing can be optimized for each combustible gas before combustion, which is thus improved for all combustible gases that are considered, since for each combustible gas a suitable insert can be provided and A suitable gas injector.
    According to one embodiment, the insert is tubular.
    The insert preferably has an annular cross section.
    According to another embodiment, the surface of the cross section of the flow path of the mixing tube is modifiable by means of the insert.

    image6
    Preferably, the cross-sectional surface of the passing current has a circular shape. By means of the mixing tube and the insert, the cross-sectional area of the flow current can be enlarged or reduced depending on the fuel gas used.
    According to another embodiment, when the fuel gas is changed, the insert and the gas injector are changeable.
    Preferably, the gas injector is screwed into a lower part of the gas burner, so that the gas injector can be easily changed. The insert may, for example, be screwed, inserted under pressure or inserted while being loose at the bottom of the burner.
    According to another embodiment, the gas injector and the insert are housed in a lower burner part of the gas burner.
    The lower part of the burner can be made in two pieces, comprising, for example, a base section, in which the gas injector is housed, and a mixing tube housing section that accommodates the mixing tube.
    According to another embodiment, the insert is inserted into the mixing tube and removable from it by an upper side of the lower part of the burner.
    In this way, it is possible to easily replace the insert.
    According to another embodiment, the insert has a circulating support flange, which is configured to rest on the upper side of the lower burner part.
    Thus, a defined position of the insert is always guaranteed when it is replaced. Preferably, the support flange is annular.
    According to another embodiment, a gas cooking point is proposed with one or several gas burners of the exposed type and with one or several gas regulating valves to regulate the flow of combustible gas directed towards the gas burner (s).
    Likewise, a gas cooker with one or several gas burners of the exposed type and / or with a gas cooking point of the exposed type is proposed.
    Preferably, the gas cooker is a household appliance.

    A procedure for changing the fuel gas of a gas burner is also proposed. The gas burner presents here a mixing tube for mixing the combustible gas with primary air, a gas injector that is configured to inject the combustible gas into the mixing tube, and a changeable and insertible insert in the mixing tube to modify the geometry of this one. The procedure presents the following steps of the procedure: replace the gas injector; change the insert; and change the fuel gas.
    Other possible implementations of the gas burner, the gas cooking point, the gas cooker and / or the process also comprise combinations not explicitly mentioned of features or embodiments described above, or below, in relation to the embodiments . Here, the person skilled in the art will also add particular aspects such as improvements or complements to the respective basic form of the gas burner, the gas cooking point, the gas cooker and / or the process.
    Other configurations and advantageous aspects of the gas burner, of the gas cooking point, of the gas cooker and / or of the process are subject to the secondary claims, as well as the examples of realization of the gas burner, of the cooking point gas, gas cooker and / or procedure described below. Next, the gas burner, the gas cooking point, the gas cooker and / or the process are explained in more detail by means of preferred embodiments, with reference to the attached figures.

    Fig. 6 shows a schematic view of a procedure for changing the fuel gas of a gas burner.
    In the figures, the same or equal function elements have been provided with the same reference symbols, as long as nothing else is indicated.
    Figure 1 shows a gas cooker 1 in a schematic top view. Gas cooker 1 is a household appliance. The gas cooker 1 has a gas cooking point 2 with a cooking hob tray 3 and with at least one gas burner arrangement 4, which has a gas regulating valve 5 which is connected to a main duct of gas 6. The gas burner arrangement 4 further comprises a supply conduit 7 and a gas burner 8. The gas burner 8 is shown in FIG. 1 in a very simplified manner. The supply line 7 connects the gas regulating valve 5 with the gas burner 8. The gas cooking point 2 can have several gas burner arrangements 4. As shown in Figure 1, the gas cooking point 2 may have five gas burner arrangements 4. The gas regulating valve 5 is configured to regulate gradually or with continuous progression or, alternatively, to interrupt the flow of combustible gas or the volumetric flow of gas directed towards the gas burner 8. Each gas regulating valve 5 is preferably attached, fixed by grip, to the main gas conduit 6.
    Figure 2 shows in schematic side view an embodiment of a gas burner 8, and Figure 3 shows a schematic sectional view of the gas burner 8. Next, reference is made simultaneously to Figures 2 and 3.
    The gas burner 8 comprises a two-piece bottom burner 9 with a base section 10, in which a gas injector 11 is housed, and with a mixing tube housing section 12 having a mixing chamber or a mixing tube 13 for mixing primary air L with combustible gas. The gas injector 11 is provided to inject the combustible gas into the mixing tube 13, which is in particular a Venturi tube. Injecting the combustible gas into the mixing tube 13, primary air L is sucked into the mixing tube 13, flowing sideways next to the gas injector
    eleven.
    The gas burner 8 further comprises an upper burner part 14 with gas outlet openings 15, which are preferably arranged evenly distributed around the perimeter of the upper burner part 14. The upper burner part 14 is supported on the lower part of the burner 9. The lower part of the burner 9 and, in particular, the mixing tube housing section 12, is connected, in particular, bolted, with a cover plate or upper plate of the gas cooking point 2 .
    image11
    image12
    image13
    Preferably, the lower part of the burner 9 and the upper part of the burner 14 are made symmetrically rotationally with respect to a central axis 16 or of symmetry (Figure 2). Alternatively, the upper part of burner 14 and / or the lower part of burner 9 may have any other geometry, for example, an oval geometry, a rectangular geometry, a pentagonal geometry, or a hexagonal geometry.
    Figure 4 shows an embodiment of the lower burner part 9 in schematic perspective view, and Figure 5 shows a schematic sectional view of the lower burner part 9. Next, reference is made simultaneously to Figures 4 and 5.
    The gas burner 8 comprises a changeable and insertible insert 17 in the mixing tube 13 to modify its geometry. The insert 17 is tubular. The mixing tube 13 has a cross-sectional area of the passing current A, which can be circular.
    The cross-sectional area of the passage current A of the mixing tube 13 is modifiable, in particular, expandable or reducible, by the insert 17. If the combustible gas is changed, the insert 17 and the gas injector 11 can be changed simultaneously. Therefore, the gas injector 11 and the geometry of the mixing tube 13 can be optimized for the fuel gas used. As fuel gas, for example, city gas, natural gas, liquefied gas, or the like can be used.
    The flame stability of the burner can be improved by adapting the geometry of the mixing tube 13 and the type of gas injector 11 to the fuel gas used, so it is possible to prevent the flame from going out undesirably. Also, the premixing in the mixing tube 13 is optimized for each combustible gas, and combustion is improved for all combustible gases, since for each fuel gas used an insert 17 and a corresponding gas injector 11 are usable. In this way, the efficiency of the gas burner 8 is increased and the emission of greenhouse gases is reduced.
    The insert 17 is housed in the lower part of the burner 9, specifically, in the mixing tube housing section 12. As shown in Figures 4 and 5, the insert 17 is inserted into the mixer tube 13 and removable again from it on an upper side 18 of the lower burner part 9. The insert 17 has a tubular base section 19 and a support flange 20 annularly surrounding the base section 19. The support flange 20 is configured to rest on the upper side 18 of the lower burner part 9.

    5 Figure 6 schematically shows a procedure for changing the fuel gas of a gas burner 8. In one step of the procedure S1, the gas injector is changed
    11. In a second step of procedure S2, the insert 17 is changed. The gas injector 11 can be changed before the insert 17, or vice versa. Finally, the combustible gas is changed in a step of the S3 procedure.
