Definitions

  • the invention relates to an electric hotplate according to the preamble of claim 1.
  • Such hot plates are usually fastened in a hob such that they engage in a mounting opening of this hob, are supported against the edge of this mounting opening against support forces and are connected to the appliance lines on the underside of the hob.
  • the width of the mounting opening is usually only slightly larger than the greatest width of the part of the hotplate body engaging in it, which is generally determined by an outer, annular cast flange edge of the hotplate body.
  • connection sections are formed only by short stubs protruding over the insulating piece, which either protrude vertically downwards in the position of use or at a small angle in the direction are angled towards the center of the hotplate body. This makes access to the connection of the device lines relatively complicated, especially if the connection is to be made by a welded connection.
  • an electric hotplate with flexible connecting sections has become known, which in particular makes the assembly or insertion of the hotplate in the hob more difficult, for example due to an automated working process.
  • an electric hotplate has also become known, on the underside of which a terminal block projecting beyond the outer circumference is attached, to which the connecting lines of the heating resistors are connected. In this case too, the electric hotplate must be installed with parts protruding over the outer circumference.
  • the invention has for its object to provide an electric hotplate of the type described, which with a simple structure ensures a significantly simplified installation in the hob or the like. And a cheap connection of the device lines.
  • the deformable, not flexible connecting pins which can only be deformed using relatively large bending forces, do not protrude so far on the one hand that they hinder a merging of the hob and hotplate, which is axially parallel to the central axis of the assembly opening, and on the other hand they project transversely to the central axis of the hotplate in such a way that they extend from the outer circumference forth, for example se in a plug-in movement, can be connected to the device lines, whereby they compensate for any slight deviations in position relative to the connecting members by their resilient mobility.
  • the hotplate according to the invention can also be designed in a simple manner in such a way that it can be stacked one above the other, for example with the interposition of a cardboard coated with foam film or a similar flat body, with similar or identical hotplates, and in such a way that hotplates lying one above the other are arranged coaxially are.
  • the hot plates can be alternately supported with their cooking surfaces and their undersides, or they can be stacked in the same orientation so that adjacent hot plates with a cooking surface and a bottom face each other, whereby the bottom cooking plate is expediently arranged with the cooking surface facing downwards is.
  • the above-mentioned stacks which ensure transport and storage in a narrow space, are possible in particular if at least one receiving recess for the connecting pins is provided in the cover in such a way that, in a transport position, they extend at most down to the underside of the hotplate, however when the stack pressure is released, spring out over the underside of the hotplate.
  • the connecting pins then move away from the underside of the hotplate, for example, at a few angular degrees to their free ends, so that their access is particularly favorable for the connection to the appliance lines parallel to their longitudinal direction.
  • connection connections and the device lines can be laid in an area in which no excessive temperatures occur due to the design according to the invention.
  • the connecting lines themselves are designed over their entire length so that they are resistant to the high temperatures.
  • the object on which the invention is based can also be achieved in an advantageous manner in that a common connecting piece is provided for all connecting pins, which has separate connecting elements arranged next to one another on an insulating body and threading guide means for the connecting pins located in the region of their front ends , so that even with automated assembly, a positionally correct connection between the connecting pins and the connecting piece or the device lines connected to it is guaranteed.
  • the connector thus contributes to the correct orientation of the pins before the final connection or before reaching its end position.
  • guiding surfaces can be provided on the one hand on the insulating body and on the other hand on the connecting members or on both parts, which are expediently arranged in such a way that they have an alignment effect in at least two coordinate directions.
  • the connecting piece has connecting or aligning members which are insulated from the connecting members for direct engagement in the hotplate, so that an exact positional alignment and possibly a direct load-bearing connection of the connecting piece with respect to the hotplate can be achieved in a simple manner.
  • the insulating body expediently protrudes with a larger part of its total length over the outer circumference of the hotplate, so that the device lines adjoining its outer end are relatively far away from the hotplate and therefore do not have to be particularly temperature-resistant.
  • connection pins can also be aligned with the hotplate before assembly by a separate centering member, this centering member engaging at a distance from the bushing through the insulating piece on the connection pins and expediently leaving their ends freely exposed at least over a short length.
  • the centering member which can be transferred from a stacking position into an assembly position, is advantageously arranged so that it gradually releases the connecting pins over the entire length on which they engage in the connecting piece when the connecting piece is connected.
  • the mechanical and securely electrically conductive connection between the connecting members and the connecting pins can be made by resistance welding, spot welding, inert gas welding and in particular by non-contact welding, such as laser welding. But it can also be done by squeezing the connecting member, by clamping screws or by pure, if necessary releasable plug connections, which is particularly advantageous when hot plates have to be replaced or replaced.
  • the connections mentioned are also suitable for connecting the connecting members to the device lines, each of the possible combinations between the type of connection with the connection pins and the type of connection with the device lines being conceivable to adapt to the respective requirements.
  • the risk that the heating resistor connecting lines are torn from their connection to the heating resistors when the hotplate is stacked or during assembly by moving the connecting pins inside the hotplate can be substantially reduced by the fact that the inner sections of the connecting lines are so opposite to the The hotplate is secured so that movements of the pins are not transferred to it.
  • the hotplate according to the invention is particularly suitable for automatic stacking and for automatic assembly using automatic handling machines (robots).
  • both the hotplate and the connecting piece or its insulating body expediently each have at least one positioning member, by means of which the position of the hotplate or the connecting piece can be precisely recognized by the handling machine and this position can be secured.
  • a device for attaching the connection piece to the electric hotplate is characterized according to the invention in that a gripper is provided which moves the connection piece in three coordinate directions with respect to the connection pins in order to bring them into engagement one after the other with the guide surfaces so that the simple way gives an accurate alignment of the pins relative to the connector.
  • a gripping and aligning device is provided for the connecting pins, preferably two gripping jaws being provided, at least one of which has a comb-like gripping surface with centering cutouts for the connecting pins.
  • the centering cutouts can be prism-shaped, for example V-shaped, in a simple manner.
