Definitions

  • the invention relates to an electric hotplate, which should have a profile plate body with a support ring, which is used for support on the top of a hob or the like and is advantageously provided in the form of a profile ring with an outwardly projecting ring leg, which has a support surface for support.
  • 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 trough 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.
  • 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 associated with the profile ring.
  • an elastically flexible seal with essentially pressure-tight abutting seat surfaces is provided in such a way 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 is carried out metal 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 ring edge can also be formed by the hotplate body and can be provided, for example, in the form of an obtuse-angled shoulder surface on its outer circumference, in which case the profile ring with an inner circumferential surface expediently rests essentially linearly on this ring edge.
  • an electric hotplate is further proposed to achieve the object on which the invention is based, in which a protective jacket is provided on the outer circumference of the hotplate body instead of the previously described design or in addition to this so that it shields the inside of the hotplate body against the ingress of water.
  • This protective jacket can extend over part or the entire height of the hotplate body and surrounds the outer flange edge of the housing in a narrow manner only with a gap.
  • the object on which the invention is based can also be achieved in that at least one drip edge, in particular the outer periphery of the hotplate body below the profile ring, is provided in a closed manner and is thus connected to the predetermined flow path of water which may have penetrated is that this inevitably gets onto the drip edge and can only get on from it by dripping or detaching it from the electric hotplate.
  • the electric hotplate 1 according to FIGS. 1 and 2 is intended for attachment to a hob that 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 embankment and in the area of its inner circumference forms an opening 4 for the partially recessed receiving of the electric hotplate 1.
  • the coaming 3 on the inner circumference which is formed by an annular bead forming its highest region with more than a quarter-circular or approximately semicircular cross-section, merges 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 coarse rim 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 8 is only slightly larger than the radial required for the support of the electric hotplate 1 Extension and the seat 8 goes radially outwards directly into a slope 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 braced against the seat surface 8 with at least one fastening screw 8, 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 over its underside in the form of a jacket, an inner flange edge 13 which lies radially within it, 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 of the central pin 14 forms the lowest zone of the hotplate body 10.
  • Over the outer periphery of the outer flange edge 12 is an essentially adjacent to the cooking surface 11 ring 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 whose outer circumference merges 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 in a contact-free 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 underside 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.
  • 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 downwards 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 annular 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, by turning it.
  • 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 edge 12 is also 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.
  • Even the creation of the profile Section 19 on the bearing surface 22 may be formed as a seal, so that there is a double or triple seal.
  • 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 degrees of angle 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 outwards 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 annular disk-shaped ring edge 28.
  • the electric hotplate 1 rests with this ring rim 28 against 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 support 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 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 angle 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 conically at an acute angle and which, like the lower end edge surface 31 of the profile ring 17 below the apex of the coaming 3 and also deeper than the support surface 26.
  • This annular shoulder 32 forms with the pressing surface 21, which is at an obtuse angle in axial section to it and extends downward, 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 an axial securing or fastening member 36, which engages, for example, in the outer circumference of the central pin 14 for captive securing against the hotplate body 10.
  • Another lower, lid-like closure for the hotplate body 10 is also formed by the jacket 5, which is cup-shaped with the cross part 6, the cross part 6 of which can lie essentially tightly against the lower end face of the central pin 14 in the center.
  • the coaming edge 3a is substantially flatter than in the embodiment according to FIGS. 1 and 2, the seating surface 8a not passing into the inner annular bead in a graduated manner, but rather a continuous one Continuation of its radially outer flank forms.
  • the seat surface 8a which is about 2 times wider than the support surface 26a, drops radially outward at a few angular degrees in cross-section and merges flatly into the main plane of the hob 2a via two mutually adjoining, opposing curvature regions.
  • the seat part 25a and the ring edge 28a fall slightly radially outward corresponding to the seat part 7a, so that the plate-spring-like ring edge 28a is still frustoconical in the tensioned position and thus the abutting sealing surfaces rise 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.
  • the opening 4b for engaging the electric hotplate is formed by an opening in the cooktop 2b, this opening being made after the coiling rim 3b has been formed.
  • the coaming edge 3b is formed radially inwards on the seat 8b or the seat part 7b to form a step-like, stepped, rising upward and engaging in the profile ring 17b, which merges into an essentially flat end wall, which is thereby in the form of an annular disk, that it is penetrated by the opening 4b which is slightly smaller than it.
  • the inner circumference of the opening 4b surrounds the profile part 20b with a small gap spacing and, moreover, the said end wall lies at a height distance below the profile section 19b approximately in the middle of the profile part 20b.
  • the profile ring 17b is substantially the same as that of FIGS. 1 and 2 trained.
  • the support surface 8b can be provided essentially plane-parallel to the high surface 11b or slightly sloping.
  • the radial extent of the profile of the profile ring 17 is substantially larger than its axial extent, namely approximately twice as large.
  • the axial extension of the profile ring 17c is several times greater in that the profile ring 17c or its inner profile part 20c merges into a protective jacket 37 which at least rests on the recessed part of the hotplate body 10c or the outer flange edge 12c surrounds part of its height, preferably over the entire height, with a relatively narrow gap distance.
  • the protective sheath 37 which is essentially straight over its entire height or up to the transition into the profile section 19c or approximately parallel to the hotplate axis, forms protective lines 37 at the lower end into a base part 38 which is formed in one piece with it, preferably essentially flat, and which has a low level Distance is below the underside of the hotplate body 10c or the outer flange edge 12c and in the central area can have a through opening for the fastening screw and an annular support surface surrounding it for support with respect to the central pin 14.
  • the common jacket part formed by the profile part 20c and the protective jacket 37 abuts the hotplate body 10c only in a line-like manner along a single annular zone, this line zone below the profile leg 18c and above the center of the height of the flange edge 12c, in particular approximately between the two upper thirds of the The height of this flange 12c is provided.
  • the linear zone can be formed in a simple manner by contacting the ring edge 33c on the inner circumference 30c of the protective jacket 37 or the profile part 20c, this system being pre-pressed can be seen that the two components are securely secured against each other.
  • the protective jacket 37 lies above and below the ring edge 33c at a gap distance from the outer circumference of the outer flange edge 12c.
  • the support surface can also be formed by an angled ring edge, but in the case shown it is a sharp, annular edge, namely the radially inner ring edge of the Edge surface of the profile leg 18c is formed, so that the support surface 26c in this case lies slightly radially within the radially outermost boundary of the profile ring 17c or the profile leg 18c.
  • the profile leg 18c extends from the resilient cross-sectional zone 29c to the support surface 26c in a substantially straight line in cross-section, so that its end edge points downward. In this respect, the support surface 26c simultaneously forms the sliding edge during the resilient deflection of the profile leg 18c.
  • a protective housing 37 forms a housing 39, which is in one piece with the profile ring 17c, for the cladding and the closure of the hotplate body 10c below the bearing surface 22c, this housing 39 also completely replacing the lower end cover for the hotplate body 10c and in the bottom part 38 the insulating body for the Carrying the connection cables can carry.
  • At least one drip edge 40 in the flow path may possibly also prevent water from penetrating into the interior of the electric hotplate water which has penetrated under the profile ring 17c can be provided in such a way that water flowing down the protective jacket 37 inevitably reaches the drip edge 40 and there is so little adhesion fin det that it inevitably tears off and drips down.
  • the annular, downward-directed drip edge 40 delimited by acute-angled flanks can be provided in the casing part, in the base part or in the transition region between the two.
  • the drip edge 40 is provided in the transition region between the jacket part and the bottom part 38 or at its radially outermost boundary where the bottom part 38 rises into the transition to the jacket part.
