- Gas hobs usually comprise a hob plate with a through hole on which a gas burner is arranged.
- the gas burner has a gas valve for providing fuel gas, the gas valve usually being arranged below the hob plate.
- the fuel gas is mixed with primary air to form a combustible fuel gas-air mixture. This is usually done in a mixing chamber that is arranged below the hob plate.
- a gas hob can include a pan support.
- the pot carrier can be provided as a removable component, for example to simplify cleaning of the gas hob.
- the pan support is usually only a support structure that is designed to hold a food container above the gas burner.
- the gas burner usually comprises a burner top which is arranged above the hob plate and has gas burner openings.
- the fuel gas-air mixture is provided at the gas burner openings in order to maintain a flame below the Gargutbereheatl age for heating the same.
- the upper burner part and the pot support are designed as separate components.
- a pan support for a gas hob which has cantilevered arms each having a support surface for a food container and gas outlet openings for providing a fuel gas-air mixture to form a flame under half of the food container.
- a “gas hob” particularly refers to a household appliance with one or more gas hobs.
- a respective gas hob has in particular a proposed pan support that can be attached to a hob plate of the gas hob.
- the "support surface” is in particular a surface on which a Gargutbenzol ter, such as a pot or wok, rests during cooking.
- a “cantilevered arm” is to be understood in particular as an arm or finger in which the loads lying on it are only diverted to one of the two sides (ends) of the cantilevered arm.
- One side is also referred to as the supported side.
- loads are meant, for example, loads that are exerted on the arm by the food container resting on the support surface.
- loads are meant, for example, loads that are exerted on the arm by the food container resting on the support surface.
- a channel can be provided in the interior of the cantilevered arm, which leads to the gas outlet openings.
- “Channel” means in particular a cavity which is surrounded along its extension by a solid material of the pot support and is set up for this along its extension to conduct a fluid, in particular the fuel gas-air mixture.
- Forming a flame is in particular the generation and maintenance of the flame by supplying - through the channel - the fuel gas-air mixture, which can be ignited outside the gas outlet openings by an igniter or the like.
- the number of self-supporting arms is preferably between three and six, particularly preferably four or five, and very particularly preferably four.
- Below the food container means, in particular, "between the food container and the hob plate when the pan support is attached to the hob plate”. Since the gas outlet openings are formed on the cantilevered arms, a functional integration can be achieved, since the cantilevered arms on the one hand carry the food container and at the same time can supply the fuel gas-air mixture to form the flame. In particular, no additional gas burner cover or a burner top part with gas outlet openings is required.
- the gas outlet openings can be arranged next to one another along a direction of extent of a respective cantilever arm.
- the gas outlet openings can particularly preferably be spaced apart from one another at the same distance.
- the cantilevered arms each extend radially outward from a central area of the pan support, and a single connecting section for connecting the cantilevered arms to a hob plate of the gas hob is formed in the central area.
- the “central area” can in particular be an area around a central axis of the pot carrier. That is, the cantilevered arms can be arranged in particular around a central axis of the pan support and extend radially outward from the central axis.
- the “connecting section” serves in particular on the one hand as a base for supporting the cantilevered arms on the hob plate.

- the connecting section can be made in one piece or in one piece.
- the cantilevered arms can be rigidly connected to one another or made of one piece of material, in particular regardless of whether the pan support is attached to the hob plate or not.

- the accessibility of the hob plate for cleaning and the like can thus be improved in a particularly advantageous manner.
- the cantilevered arms extend obliquely upwards from the central area.
- the cantilever arms run obliquely upwards in their radial course outwards. "Up” means in particular a direction away from the hob plate when the pan support is attached to the hob plate. In other words, a distance between the respective cantilever arm and the hob plate can increase towards the outside in the attached state of the pan support.
- An angle of inclination of the arms running obliquely upward is preferably between 10 ° and 20 °, particularly preferably between 10 ° and 15 ° and very particularly preferably 13
- the support surface for the food container is arranged radially outside the plurality of gas outlet openings in a respective cantilevered arm.
- a central flame can thus advantageously be provided under an underside of the food container.
- the gas outlet openings located radially on the inside are also arranged at a lower level than the support surface located on the radial outside. In this way, a distance between the gas outlet openings and the underside of the food container placed on the support surface can be increased and, as a result, the underside of the food container can advantageously be placed better at a point of greatest heat of the flame.
- a respective cantilever arm has a protrusion at its free end.
- the support surface for the food container is formed by a surface of the protrusion.
- protrusion is to be understood as meaning, in particular, an upward protrusion, with “top” denoting a direction which, when the pan support is attached, points away from the hob plate along a surface normal of the hob plate.
- the support surface is formed by a surface of the upwardly pointing protrusion
- a distance between an underside of the food container placed on the support surface and the gas outlet openings of the cantilevered arm can be further increased and the underside of the food container even more favorable at a hottest point of the Flames formed by the gas outlet openings are placed.
- the bearing surface in particular the bearing surface formed by the surface of the protrusion, has a horizontal section and an inclined section.
- “Horizontal” refers in particular to a direction which, when the pan support is attached, runs parallel to the hob plate. "Inclined” refers in particular to a direction that runs obliquely to the hob plate when the pan support is attached. In particular, the inclined section of the surface of the protrusion can run more steeply upwards than a surface of the cantilevered arm in the area between the central area and the protrusion.
- An angle of inclination of the inclined section is preferably between 20 ° and 30 ° and particularly preferably 25 °.
- a pot or pan can advantageously be placed on the horizontal sections of the bearing surfaces of the cantilevered arms.

- the two arm sections of the cantilevered arm run axially symmetrically to a radial central axis of the cantilevered arm.
- the intermediate space can in particular be formed at least in a radial section of the cantilever arm.
- the space can extend in the radial direction from the central area to the protrusion.
- the gap can also extend over the entire radial extent of the cantilevered arm to its free end.
- the space in the radial direction of the cantilevered arm can be open to the outside.
- two arms or fingers running parallel or essentially parallel to one another with an intermediate space in between are also referred to as two arm sections of one and the same cantilever arm.
- the total number of gas outlet openings of the cantilevered arm can advantageously be increased, and thus the combustion output provided by the cantilevered arm can be increased.
- the inner gas outlet openings are connected to a first channel and the outer gas outlet openings are connected to a second channel, the first channels being connected to a first gas connection and the second channels being connected to a second gas connection of the connecting section.
- a respective gas connection of the connecting section is set up in particular to receive gas from a respective corresponding gas valve provided below the hob plate when the pan support is attached.
- two gas valves can be provided on or under the hob plate for the gas hob formed by the pan support.
- the pan support can thus enable the corresponding gas hob to be operated with different power levels.
- the flame can optionally be provided only on the outside, only on the inside or both on the outside and on the inside gas outlet openings of the cantilevered arms of the pot support.
- two adjacent cantilever arms together form a corner.
- the gaps between the neighboring cantilever arms and the corner are connected by an ignition channel.

- the burning fuel gas-air mixture can then pass through the ignition channel to the spaces between the Spread out adjacent cantilever arms and cause an ignition of the fuel gas-air mixture flowing out of the gas outlet openings inside.
- the proposed structure with ignition channels thus advantageously enables a simple ignition of the fuel gas-air mixture, which is provided by the pot support with the cantilevered arms, which have both external and internal gas outlet openings.
- the self-supporting arms are designed as a one-piece or one-piece support structure.
- “Material in one piece” means that the support structure of the pot carrier and / or the pot carrier is made, in particular originally formed, from a base material or raw material.
- the support structure and / or the pot support is produced by means of 3D printing.
- a one-piece support structure there is no need for complex joining steps during manufacture.
