Definitions

  • the invention relates to an electric hotplate according to the first part of patent claim 1.
  • the profile ring or the support leg is between approximately 4 and 8 mm high, with decreasing height it becoming increasingly difficult to achieve such a closed contact of the profile ring on the top of the cooker hob or a coiling rim molded into it. that no liquid penetrates to the hotplate body under the hob if a relatively large amount of liquid flows over the profile ring or is in the hob.
  • an electric hotplate has become known, the profile ring of which is provided essentially only for carrying the hotplate body on the hob and possibly for shielding its receiving opening for the electric hotplate, but not for sealing this receiving opening.
  • the profile ring is only suitable for securing the inside of the cooker against the overflow of boiling-over food in the manner of a barrier, i.e. only against free flow, but not to prevent liquid from creeping through.
  • the invention has for its object to provide an electric hotplate of the type mentioned, in which disadvantages of known designs are avoided or in which it is made possible in particular in a simple manner to prevent liquid or water from the top of the hob through the seat of the Profile ring can get into the hotplate body, for example, up to electrically conductive parts.
  • a seal is assigned to the profile ring.
  • an elastically resilient seal with essentially pressure-tight abutting seat surfaces is provided so that any penetrating water would have to pass through this seal, but through the seal from the Flow or crawling is blocked.
  • the design according to the invention makes it possible to install a stove top designed as a built-in hob with a single electric hotplate or with two or more directly next to a sink or sink, as can be expedient for very small kitchens.
  • the sealing has a particularly high fatigue strength if the seats are metallic, ie the sealing takes place against metal. With sufficiently fine machining or close tolerances, a pressure-tight seal can be achieved even without a labyrinthine design of the interlocking seat surfaces. It is also conceivable to form a seat surface of the seal from a glass-like material, for example an enamel, with which the sheet metal body of the hob can be coated.
  • At least one seat part is formed by the profile ring, this is expediently made from sheet metal that was previously thinner in such a way that it has relatively good bending spring properties with regard to the inner and / or outer profile leg and the respective profile leg as the seat part is elastically resilient either on a counter surface of the hob or abuts a counter surface of the hotplate body.
  • the seat surface by an essentially sharp-angled ring edge, for example the edge surface lying on the outer circumference of the profile ring, particularly good sealing conditions result if the sealing surface has a greater radial extension, in particular a two to five times greater than the sheet metal thickness of the profile ring Has radial extension.
  • the electric hotplate 1 according to FIGS. 1 and 2 is intended for attachment to a hob 2, which is deep-drawn, for example, from sheet steel, from which, for each electric hotplate 1, a closed rim 3 surrounding it is pulled out in such a way that it is on the outer circumference of the electric hotplate 1 kind of sloping slope and in the area of its inner circumference forms an opening 4 for the partially recessed receiving of the electric hotplate 1.
  • the coaming edge 3 merges on the inner circumference, which is formed by an annular bead forming its highest region with a more than quarter-circular or approximately semicircular cross-section, into a downwardly extending jacket 5, which extends from the radially inner leg of this annular bead and which forms the recessed part surrounds the electric hotplate 1 with a small gap distance without contact and merges at the lower end into a transverse part 6 formed, for example, by an approximately closed bottom.
  • the coaming edge 3 merges into an approximately annular disk-shaped seat part 7 which is slightly lower than the apex of the annular bead and which forms an annular shoulder-shaped seat 8 on its upper side.
  • This seat surface 8 can be formed approximately parallel to the level of the hob or to the cooking surface of the electric hotplate 1 or, in contrast, at a few degrees of angle falling radially outwards.
  • the radial extent of the seat surface 8 is only slightly larger than the radial extent required for supporting the electric hotplate 1 and the seat 8 goes radially outwards directly into an embankment part falling at an angle of approximately 45 °, which directly adjoins the essentially lowest plate level of the hob 2.
  • the electric hotplate 1 is clamped against the seat surface 8 with at least one fastening screw 9, which expediently passes through a through opening in the transverse part 6.
  • the electric hotplate 1 has a cast iron hotplate body 10 which forms an essentially flat and annular cooking surface 11 on its upper side.
  • This cooking surface 11, like the hotplate body 10, can be round or circular or angular, for example rectangular or square, on the outer circumference, in which case the coaming 3 also expediently has a correspondingly adapted basic shape.
  • the hotplate body 10 forms an outer flange edge 12 which is set back slightly from its outer circumference and projects beyond its underside in the form of a jacket, an inner flange edge 13 which lies radially within it and protrudes less far downward, and a central pin 14 which in turn lies radially within it. which protrudes downward approximately as far as the outer flange edge 12, so that the lower end face of the flange edge 12 or the central pin 14 forms the lowest zone of the hotplate body 10.
  • Over the outer circumference of the outer flange edge 12 is an essentially adjacent to the cooking surface 11 annular collar 15, the outer width of which is greater than the inner width of the opening 4 intended for receiving the outer flange edge 12 and the outer circumference of which is milled into the cooking surface 11.
  • At least one spiral groove for receiving at least one heating resistor 16 in the form of a resistance wire coil, which is embedded in the associated spiral groove relative to the hotplate body 10 without contact in a pressed insulating compound.
  • bare connecting pins project downwards over the insulating compound, these connecting pins below the insulating compound and above the underside of the hotplate body 10, for example, inside a closed space lying approximately parallel to the cooking surface 11, bare, inherently rigid Connection wires are connected, which are angled out through an insulating body from the bottom of the electric hotplate and are intended for connection to the stove's operating lines or the like.
  • a profiled ring 17 made of sheet metal is fastened to the hotplate body 10 only by pressing, which protrudes beyond the outer circumference of the hotplate body 10 or the ring collar 15 and completely below the thickness of the ring collar 15 the plateau 11 lies.
  • the profile ring 17 sits under pressure on a pressing surface 21 formed by the outer circumference of the outer flange edge 12, which is widened at an acute angle in cross-section downward at a few angular degrees and upwards via a partially circular, concave fillet in an approximately flat, annular shoulder-shaped bearing surface 22 passes, which is formed by the underside of the collar 13 and is approximately at the level of the bottom surfaces of the ring grooves for receiving the heating resistors 16.
  • the radius of curvature of the fillet is expediently smaller than the radius of curvature of a transition area between the profile section 19 and the profile part 20, which in part also engages convexly in this fillet and is also approximately circular in cross section, so that the fillet and the transition section lie completely without contact with one another.
  • the upper side of the profile section 19 rests approximately over the entire surface of the support surface 22 of the hotplate body 10, for example, machined by turning.
  • the support of the profile ring 17 on the seat part 7 of the hob 2 is provided as a seal 23 so that any water standing on the hob 2 up to the level of this support does not pass under the profile ring 17 into the opening 4 and thus on the outer circumference of the flange edge 12 and from there to the described electrically conductive parts of the electric hotplate 1.
  • the engagement of the profile part 20 in the flange 12 is formed as a seal 24, so that water cannot penetrate between the top of the profile ring 17 and the hotplate body 10 in the manner described.
  • the creation of the profile section 19 on the bearing surface 22 can be designed as a seal, so that there is a double or triple seal.
  • the seal 23 of the profile leg 18 forms with its lower end the complementary to the seat part 7 seat part 25, which forms on its underside an annular disk-shaped support surface 26 of constant width that extends to the greatest outer width of the profile ring 17 or the electric hotplate 1, which as in Axial section rectilinear sealing surface rests resiliently biased over the entire surface of the seat surface 8 in that the seat part 25 can be deflected in a springy manner relative to the hotplate body 10 by a small amount or with a high spring progression.
  • the seat part 25 is shown in dash-dot lines in its relaxed state, in which the support surface 26 in axial section with respect to the seat surface 8 assumes a very small angle of one to a few angular degrees that closes radially outward.
  • the ring edge delimiting the support surface 26 on the outer circumference, which forms the transition to the radially outer ring edge surface of the seat part 25, is slightly lower than the rest of the support surface 26, so that this ring edge can form a sliding edge 27 which, when the electric hotplate 1 is inserted into the Stove recess 2 rests first and only on seat 8.
  • the seat part 25 is deformed in the direction of an imaginary flat state and is slightly expanded radially, during this Deformation the sliding edge 27 can slide radially outward on the seat 8 by a small amount of, for example, substantially less than one millimeter, and at the same time the angle between the seat 8 and the support surface 26 closes until the latter is in full contact with the seat 8.
  • the seat part 25 thus forms sections over the circumference which can be subjected to different deflections within the required, relatively small, but existing tolerance deviations, such tolerance deviations also being able to result, for example, when the profile ring 17 is mounted on the hotplate body 10.
  • the support surface 26 which is offset or angled with respect to the inner circumference of the main part of the profile leg 18, the radial extent of which is slightly smaller than that of the seat surface 8 or corresponds approximately to 1.5 times to 5 times, preferably approximately 3 times the sheet thickness of the profile ring 17 the profile leg 18 is angled at its outer circumference in the axial section at an obtuse angle to an approximately ring-shaped ring edge 28.
  • the electric hotplate 1 rests with this ring edge 28 on the hob 2, while it or the profile ring 17 is otherwise radially or axially spaced apart from the hob 2.
  • the rising main section of the profile leg 18 is also contact-free with respect to the associated flank of the annular bead of the coaming edge 3
  • the material thickness, the cross-sectional shape and the material of the profile ring 17 are coordinated so that the profile leg 18 in its circumferential direction has a low tensile elasticity for the resilient absorption of the expansion forces and, in addition, can be deflected slightly around that cross-sectional zone 29 which is partially circular in cross section and formed by obtuse-angled sections, which forms the transition between the profile leg 18 and the profile section 19.
  • This curved cross-sectional zone 29 lies essentially completely radially outside the hotplate body 10 or the bearing surface 22, to which it connects tangentially.
  • the average radius of curvature of this cross-sectional zone 29 is several times greater than the material thickness of the profile ring 17, while the transition to the ring edge 28 is approximately sharp-angled or such that the associated average radius of curvature is approximately in the order of magnitude of the material thickness of the profile ring 17.
  • the profile ring 17 is only in engagement with the hotplate body 10 or the pressing surface 21 with a ring edge 30 which is essentially sharp in cross section, this ring edge 30 being formed by the radially inner edge of the lower end edge surface 31 of the profile part 20.
  • the profile part 20 is conically tapered downwards at an acute angle or lies in axial section at a small, downwardly closing angle to the pressing surface 21, the oppositely closing cone angles of the profile part 20 and the pressing surface 21 being approximately the same size.
  • the lower end edge surface 31 is expediently one or more times the material thickness of the profile ring 17 higher than the support surface 26. Between the ring edge 30 and the support surface 22, the profile ring 17 is non-contact with the hotplate body 10.
  • the outer circumference of the outer flange edge 12 forms a stepped ring shoulder 32 which is widened at an acute angle and which, like the lower end edge surface 31 of the profile ring 17 below the vertex of the coaming 3 and also deeper than the support surface 26.
  • This annular shoulder 32 forms with the pressing surface 21, which lies at an obtuse angle in axial section to it and extends downwards, an obtuse-angled cross-section 33 which determines the largest outer circumference of the outer flange edge 12.
  • the underside of the hotplate body 10 can still be closed by a cover 34 belonging to the preassembled electric hotplate 1, which, expediently, at least in its radially outer area extending almost to the outer flange edge 12, essentially completely above the underside of the hotplate body 10 or the lower end face of the
  • the flange 12 lies and can be supported, for example, within the flange 12 with an annular disk-shaped support edge 35 on the underside of the insulating compound for the heating resistor 16, directly adjacent to the inner circumference of the flange 12.
  • the end cover 34 has, for example, an axial securing or fastening member 36 which engages in the outer circumference of the central pin 14 for captive securing against the hotplate body 10.

  • the seat part 25a or the ring edge 28a fall slightly radially outwards corresponding to the seat part 7a, so that the plate-spring-like ring edge 28a is still flat in the shape of a truncated cone even in the tensioned position and the sealing surfaces which lie one against the other increase slightly radially inwards.
  • the coaming edge 3a or its ring bead lies essentially completely below the profile part 20a or extends its apex to approximately the height of the ring edge 30a, so that the coaming edge 3a engages at most only slightly in the underside of the profile ring 17a.
