Definitions
- the invention relates to an electric hotplate with a hotplate body and is designed according to the invention for flat installation to achieve space-saving installation.
- the invention also relates to an electric hotplate in which the hotplate body forms a cooking surface directly on its side facing away from the underside and is expediently designed to have different heights in the area of the underside, it being possible for it to be provided with at least one engagement member which cooperates with a holding element is used, with which the hotplate is secured against a hotplate, in particular in that the hotplate is tensioned downwards or against an upward-facing contact surface of the hotplate.
- the holding element is located relatively deep below the undersides of the electric hotplates, and in this respect more height is required on the underside of the hotplate than would be required per se due to the engagement height of the electric hotplates.
- the invention is further based on the object of creating an electric hotplate of the type mentioned, in which the disadvantages of known designs are avoided and with which, in particular, a reduction in the overall installation height thereof is possible in a simple manner.
- the hotplate body is designed to be flatter in a thermally protected manner, for example essentially has a lower overall height in its radially outer region.
- At least one receiving recess is expediently provided on the underside for the recessed receiving of at least a part of the holding element.
- the underside of the hotplate body is profiled in a variety of ways, namely with projections projecting downwards.
- the hotplate body can have an outer flange edge which is located near its outer circumference and an inner flange edge which is provided near a recessed zone in the cooking surface, an annular, less protruding heating zone being delimited between the two flange edges and having, for example, at least one spiral groove with at least one heating resistor embedded in an insulating compound on the underside of the hotplate body.
- the inner flange edge usually projects less far down than the outer flange edge, which can determine the lowest level of the underside of the hotplate body with its end face.
- a central pin can also protrude on the underside, which is expediently provided in the central axis of the hotplate and is surrounded at a radial distance by the inner flange edge or the heating zone.
- This center pin can protrude as far as the outer flange edge, but it is particularly useful if the lower end face of the Center pin is at least by the thickness of the holding element or by the depth of the receiving recess higher than the lower end face of the outer flange edge or as the lowest level of the rest of the hotplate body.
- an electric hotplate of the type mentioned also consists in that at least one receiving recess for the holding element is provided directly to prevent the hotplate from rotating relative to the hotplate, preferably the side flanks of the receiving recess being directly used as anti-rotation stops are assigned to the outermost side edges of the holding element, so that no separate anti-rotation element needs to be molded out of the holding element or from its central section lying on the underside of the hotplate. Rather, the entire anti-rotation element or its part engaging in the underside of the electric hotplate is at the same height as the central portion of the holding element, so that no additional height is required for the anti-rotation element.
- the holding element can be cup-shaped or bowl-shaped for one or more hot plates, star-shaped or cruciform or similar, but this results in a particularly simple design if the holding element is strip-shaped with an essentially constant strip width and the width of the receiving recess corresponds to the Width of the holding element is adapted, since then a particularly simple alignment of the hotplate with respect to the holding element is possible and good ventilation of the hotplate is ensured.
- the holding element can have a width that is substantially the same as the outer diameter of the central pin or only slightly larger.
- At least two mutually opposite receiving recesses are provided in the outer flange edge of the hotplate body, these receiving recesses being of the same size or so can be designed so that the hotplate can be mounted equally well in two positions rotated by 180 ° to each other.
- the underside of the hotplate body is usually expediently closed with an end cover made of sheet metal or the like, which expediently projects at most by at least its material thickness above the underside of the hotplate body and has an annular rim at the lowest level of the hotplate body, that is to say on the lower end face of the outer flange edge.
- This will underside the hotplate formed by the underside of the end cover, this underside being about the material thickness of the end cover deeper than the underside of the hotplate body and at least in a stacked state no further parts projecting beyond the underside of the hotplate.
- this end cover can also be designed for the recessed receiving of the holding element, for which purpose the end cover expediently has, on the underside, a receiving recess which is adapted to the outer contour of the holding element, for example diagonally or radially groove-shaped.
- the end cover can be secured to the hotplate body with respect to the central pin, for example with claw members, with respect to its outer circumference or with a screw engaging in a threaded hole in the central pin. If this screw is designed as a hollow screw, it can receive a holding screw which passes through the holding element and with which the hotplate can be clamped downward against the holding element.
- the receiving recess or receiving recesses in the hotplate body are also suitable for securing the end cover against twisting in relation to the hotplate body in the predetermined mounting position, for serving as alignment aids or markings for an automatic handling device (robot) during the assembly of the electric hotplate and / or also to help prevent the entire electric hotplate from rotating relative to the hotplate.
- the end cover expediently has an attachment on the edge for the respective receiving recess of the hotplate body, which engages in the associated receiving recess of the hotplate body. This, projecting upwards Appropriate approach forms on the underside of the hotplate or the end cover itself a receiving recess for example for the engagement of the holding element.
- the attachment is designed in the manner of a lining of the cutout forming the inner surface of the receiving recess in the outer flange edge of the hotplate body, so that the effective receiving recess is narrower than the material thickness by about twice and less by the material thickness There is a recess in the hotplate body.
- the bottom part of the diagonal groove-shaped or similar receiving recess of the end cover can be clamped directly against the central pin of the hotplate body and e.g. be supported on its lower end face.
