Definitions

  • the invention relates to a hotplate according to the preamble of claim 1.
  • Such hobs can be formed, for example, by a table top into which the mounting plate is inserted or by the upper housing plate of a stove housing enclosing an oven.
  • the window opening is, in order to ensure good accessibility for the connection of the electric hotplate, as a rule relatively large, but then after the electric hotplate is connected, its associated area, which has numerous bare electrical conductor parts, is exposed, so that it is on the one hand can easily become dirty or be fogged with condensation and, on the other hand, accidental contact with electrically conductive parts is possible.
  • the invention has for its object to provide a hob or a lower cover of an electric hotplate, with which an at least partial shielding of the connection area of the electric hotplate is ensured in a simple manner.
  • a hotplate of the type described at the outset according to the invention in that the hotplate is covered in the area of the clamping part and the electrical connection area.
  • a closure part is expediently provided for at least partially closing a window opening for supplying connection connections, the closure part having at least one passage for the connection connections to the connection members.
  • the advantageously completely detachable or removable closure part can close the remote window almost tightly, so that the lower cover, usually formed by the tensioning part of the electric hotplate, forms a closed housing space with the hotplate and even in the case of accessibility to the underside of the hotplate As a result of the complete shielding, there is no risk of accidental contact with electrically conductive parts. This is particularly the case if the tensioning part is designed like a cover and not, like also possible, in the form of a bow or star.
  • the lower cover or the clamping part can be designed separately for the respective electric hotplate in the case of a hotplate which has two or more electric hotplates or can be formed by a component which is common for two, more or all electric hotplates and which expediently follows Type of a profiled plate with plate-shaped shallow depressions for engaging the respective electric hotplate and with beads or similar profiles for stiffening is provided.
  • the clamping part expediently lies with a peripheral edge essentially over the entire surface on the underside of the hotplate, as a result of which it is supported against the clamping forces and an essentially tight connection is provided.
  • a connector is provided for connecting the connecting lines to the connecting members of the electric hotplate, which is preferably in the area of the closure part and in particular has an insulating body.
  • the insulating body is expediently designed such that the connecting lines are provided with an insulating jacket at least up to its associated outer surface, in particular projecting into it, so that even when the insulating body protrudes outward above the cover or the closure part, no bare parts are provided exposed electrically conductive parts.
  • the closure part or its insulating body can lie completely on the inside of the closure part or completely on the outside or protrude both over the inside and over the outside of the closure part.
  • the closure part is provided at least in the closed position on the connection piece, so that it can be precisely aligned by connection with it or held on the connection piece and, if it is also attached to the tensioning part, exactly opposite it Aligns window opening.
  • closure part is formed by a separate component, for example made of sheet metal, it expediently has a through opening for the connecting lines or for the connecting piece or its insulating body, this through opening being expediently closely matched to the outer contour of the insulating body.
  • the closure part can thus consist of a ceramic material, for example steatite or the same material as the insulating body.
  • a too tight or shielded closure of the underside can lead to undesirably high temperatures.
  • This can be achieved by maintaining at least one ventilation opening while maintaining the advantages mentioned can be counteracted, which can be at least partially or at least one of which can be formed by part of the window opening, so that the possibly circulating air can be guided along or through the connector or its insulating body.
  • the window opening is advantageously closed in its area which is further away from the central axis of the hotplate or closer to the circumference of the clamping part, while the part lying further radially inward is open in the manner described.
  • the connection area of the hotplate or connection elements on the underside of the clamping part can be at least partially exposed.
  • connection of the electric hotplate can be carried out in a particularly simple manner if the connecting piece is designed for a plug connection with the connecting members and / or the connecting lines.
  • the closure part connected to the connection piece or formed by it can be held in its closed position, in particular in the case of such a design, only by the connection of the connection piece to the connection members.

  • a suitable connection in particular a plug connection.
  • the plug-in direction of this plug-in connection is expediently approximately parallel to the plug-in direction of the connecting piece for the connection to the connecting members of the electric hotplate, so that both connections can be made simultaneously by a single plug-in process.
  • the closing part can easily form a strain relief for the connecting lines or the connecting piece and a separate strain relief can be dispensed with.
  • a very simple connection of the closure part with the tensioning part results, for example, from the fact that the closure part interacts with edge zones of the window opening, for example it can overlap these edge zones at least on the inside or the outside of the tensioning part in such a way that it closes at at least one boundary edge the window opening is supported against displacement movements.
  • the closure part can also have grooves receiving or engaging around the edge zones.
