  • the gas hob comprises a gas input or inlet adapted to supply gas to the gas hob for operating the same.
  • the gas hob is adapted and configured to be moveable between different cooking positions within and relative to a cooking face of the gas cooktop.
  • Respective movements may comprise at least one of a linear and circular or pivoting movement.
  • Linear movements of the gas hob may comprise movements in a direction parallel to the cooking face and/or in a direction perpendicular to the cooking face. During movements perpendicular to the cooking face, the gas hob may be raised and lowered relative to the cooking face. Circular or curved movements of the gas hob relative to and/or within the cooking face may be provided to place and/or transfer the gas hob between different cooking locations.
  • Respective cooking locations may either be single cooking locations in which each cooking hob of the gas cooktop makes up a single cooking zone; or be a combined cooking location or cooking zone in which two or more gas hobs are combined to make up a unique and enlarged cooking zone.
  • the gas cooktop further comprises a gas supply source with a gas output, i.e. a gas outlet, and a gas feeding unit which is adapted to supply gas from the gas supply source to the gas hob.
  • the gas feeding unit is adapted and provided to connect the gas output of the gas supply source to a gas input of the gas hob.
  • the gas input to the gas hob is arranged stationary relative to the gas hob.
  • the gas input moves in concert with movements of the moveable gas hob, and in particular moves relative to the gas output of the gas supply source, which gas output is provided and arranged stationary relative to the cooking face.
  • the gas output of the gas supply source is stationary relative to the cooking face, and that the gas hob and gas input of the gas hob are moveable relative to the cooking face. Hence any movement of the gas hob will result in a relative movement between the input and output.
  • the gas feeding unit is adapted and configured to balance or compensate any changes in the relative position and orientation between the gas input of the gas hob and the gas output of the gas supply source during a movement of the at least one gas hob.
  • the gas feeding unit may be adapted to compensate changes in position and orientation of the input relative to the output, caused or induced by a movement of the moveable gas hob relative to the cooking face.

  • a respective moveable gas hob or a group of moveable gas hobs may be positioned on a moveable platform, in particular a turntable, which may for example be adapted to be moveable, in particular in linear and/or pivotable movements, within the cooking face. By moving the platform, the at least one gas hob may execute corresponding movements.
  • Linear and/or pivoting movements of the gas hob relative to the cooking face result in movements of the gas input of the gas hob relative to the gas output of the gas supply source.
  • Relative movements between the input and output may be bridged and compensated by the gas feeding unit in particular to provide gas hobs that can easily and in a user friendly way be moved along the given trajectories of linear and/or curved shape.
  • the gas feeding unit comprises a gas hose or gas supply line that comprises at least one flexible and bendable section.
  • the flexible and bendable section is adapted and configured in such a way that changes in position and orientation between the input of the gas hob/s and output of a corresponding gas supply are compensated during movements of the at least one moveable gas hob.
  • At least one flexible and bendable section shall comprise embodiments in which the hose is flexible and bendable over essentially the whole axial length, except for possible end sections or end connectors, in particular fittings or end terminals.
  • Flexible and “bendable” in particular shall mean that the hose is able to change its course or path by changing or altering the curvature and/or inflection.
  • the hose may be adapted to allow a continuous variation of curvature. This in particular shall mean that the hose may be adapted to allow a variety of different curve shapes, may it be left-handed bends, right-handed bends and/or straight sections. As to the bendability of the hose, the hose may be adapted to allow bending radii as low as approximately 2 cm.
  • the gas hose may be made from a gas-tight material allowing respective bendings, in particular repeated bendings.
  • the gas hose may comprise a corrugated outer shell providing sufficient flexibility.
  • the gas hose may comprise at least one stiff and non-bendable section.
  • a respective stiff and non-bendable section may be advantageous for obtaining or implementing more favourable bending radii of the bendable hose sections during movements of the gas hob.
  • the stiff and non-bendable sections may be favourable to restrict the lower limit of the bending radii of the flexible sections of the gas hose.
  • the stiff and non-bendable section may be implemented as a single straight and/or bent section, or as a combination of several straight and/or bent sections.
  • the at least one stiff and non-bendable section may be provided in or at an end section of the gas hose.

  • the cladding is adapted and configured to avoid or at least greatly reduce at least one of contact wear and movement noise of the gas hose.
  • Contact wear and movement noise may occur during a movement of the moveable gas hob.
  • the gas hose compensates or balances changes in the position and orientation of the gas output of the gas supply and gas input of the gas hob.
  • a respective compensation and balance requires the hose to change its path, in particular curvature.
  • the hose may drag along a support face and thereby generate noise and/or be exposed to contact wear.
  • the proposed cladding which may be provided either over the whole length of the gas hose or be provided at least in predefined sections of the gas hose, is intended to overcome movement nose and contact wear.
  • spacers may be used to prevent, or at least greatly avoid, movement noise and/or contact wear.
  • the cladding is made of or comprises at least one of the following materials: plastic, silicone rubber, PTFE (polytetrafluorethene), and fiber glass.

  • Providing a gas distributor in particular is of advantage if several gas hobs are placed on a moveable platform and can be jointly moved by moving the platform, which in particular may be a turntable.
  • the gas distributor in this case can be simultaneously connected to several gas hobs, or in other words can supply several gas hobs with gas. If the moveable gas hobs are mounted to or on a turntable or rotatable platform, the gas distributor may be positioned in the center of rotation with supply ducts leading to off-center gas hobs.
  • the gas distributor in general may be implemented to comprise one or several outputs, in particular output ducts, respectively connected to an input of a moveable gas hob. In this way, a comparatively easy and stationary gas supply on and within a moveable platform can be obtained.
  • a gas input of the gas distributor is connected to the output of the gas supply source.
  • gas can be supplied from the gas supply source to the moveable gas hob/s via the gas distributor.
  • the input of the gas distributor is connected to the output of the gas supply source via a gas hose, which may at least in sections be flexible and bendable, configured to compensate changes in the relative position and orientation between the input of the gas distributor and the output of the gas supply source during movements of the gas hob.
  • the gas hose may comprise one or more stiff and non-bendable sections, may comprise a cladding as set out above, and may comprise respective terminal end connections. Other features and characteristics may be readily adapted.
  • the gas distributor is attached to be pivotable around the pivot axis in concert with the gas hob.
  • stiff and non-bendable ducts can be used for connecting the moveable gas hobs to the gas distributor. This may provide cost reductions, as the number of comparatively elaborate flexible hoses can be reduced.
