Definitions

  • the invention relates to an electric hotplate with a hotplate body and a cover plate covering its underside, which is fastened by means of a screw to a pin of the hotplate body, the screw or the like also for fastening the electric hotplate to a stove, a hob or the like. serves.
  • a conventional hotplate of this type is known from CH-A-262 513, DE-C-631 467 and GB-A-451 052.
  • a threaded bolt is screwed into the central pin of the hotplate body and a cover plate is fixed by means of a nut screwed thereon, possibly with the interposition of a spacer sleeve.
  • two screwing operations must be carried out.
  • the threaded bolt protrudes far from the hotplate, so that the pack dimensions are twice as large as the entire hotplate height and, moreover, an axial offset between the two during transport neighboring hot plates must be made if you do not want to enlarge the pack size even further.
  • the protruding part of the threaded bolt is intended to fasten the hotplate to a bracket by means of a further screwed-on nut, whereby the hotplate is stretched downwards.
  • the object of the invention is to further improve the above-mentioned hotplate in such a way that the mounting and storage or transport costs are reduced if the cover plate is fastened more advantageously.
  • the screw is a hollow cap screw with an external and internal thread, which fixes the cover plate with its head, and into which a fastening screw for the electric hotplate can be screwed.
  • the center bolt was previously used (see CH-A 262 513) to fasten the earth connection.
  • Earth connection cables were often placed on the central threaded bolts by screwing them down.
  • the invention provides an improvement in that between the cover plate holding the screw which can be screwed into the central pin of the hotplate and the cover plate, at least one sheet metal part with at least one section which projects outward from the central region and is readily bendable is clamped. Earthing cables can be plugged, clamped or welded onto the ends of the cable.
  • the same or a corresponding sheet metal part can advantageously also be used to create an anti-rotation device.
  • pins that protruded downward from the center of the usual hot plates were riveted to the cover plate, which engaged in corresponding holes in the fastening parts.
  • two of the sections can have ends which can be bent off from the cover plate and which cooperate with fastening parts on the stove, the hob ⁇ or the like, in order to prevent rotation of the electric hotplate. These ends can still lie flat against the cover plate during transport and are only bent downwards by approx. 90 ° when they are required to prevent rotation during assembly. It is also advantageously possible to create an anti-rotation element that does not interfere with transport, in that at least one sleeve-like recess, closed to the interior of the hotplate, is provided in the lower cover plate of the electric hotplate for receiving an anti-rotation pin fastened to a fastening part.
  • the cover plate is not interrupted and nevertheless - a recessed anti-rotation lock is created.
  • the associated pin is not attached to the hotplate here, but rather to the fastening parts, for example a bracket passing under the hotplate, and therefore does not interfere with transportation.
  • an electric hot plate 11 which has an existing cast-iron cooking plate body 12 having an upper planar and closed cooking surface .13.
  • the unheated central zone 14 is lowered so that an annular cooking surface is formed.
  • the hotplate body overlaps on its outer circumference via an overflow edge 15 made of sheet material of essentially U-shaped cross section, which is supported on the raised opening edge 16 of the worktop 17 of an electric cooker or hob.
  • the hotplate In the heated ring area, the hotplate is provided with spirally extending ribs, which likewise form spiral grooves 18, in which heating coils 19 are located in ceramic investment material 20.
  • the edge 21 has a recess 26 in the form of a square cutout (FIG. 8), in which a corresponding design 27 of the cover plate is placed and thus ensures that the cover plate 24 is secured against rotation on the hotplate body despite a relatively tight seal.
  • the shape 27 of the cover plate in turn ensures that the finished hotplate can be aligned in the circumferential direction when it is being handled during manufacture. As a result, no inner projection is necessary on the edge 21.
  • the step 25 is followed by an area 28 of the cover plate which springs back relative to the edge area 23 and is adjoined by a central area 29 which projects somewhat from the edge area 23.
  • the hotplate body has a downwardly projecting pin 30, into which a blind threaded bore 31 projects from below.
  • a hollow cap screw 32 which is shown in detail in FIG. 9, is screwed into this threaded bore. It consists of a sheet metal stamping or deep-drawn part with a flange-like head region 33 with a hexagon key surface and an adjoining sleeve-shaped threaded section 34, into which an internal and external thread is pressed or pressed.
  • the screw 32 protrudes through a central hole 36 of the cover plate 24 and is screwed into the thread 35 of the bore 31, so that the cover plate 24 is pressed with its edge region 23 against the lower edge 22 of the edge 21 of the hotplate body 12.
  • a sheet metal part 37 (E'ig.2) is interposed, which has the shape of a sheet metal strip, which has a hole 38 on one side through which the Screw 32 protrudes, while the other end is somewhat tapered and comprises a delivery line 40 with a bent end 39 (FIGS. 1 and 2).
  • the grounding line can be pressed or welded to the sheet metal part 37.
  • This sheet metal part is simply placed under the screw head 33 in the manner of a washer and enables a safe earth connection. It is particularly advantageous that the sheet metal part lies flat against the underside of the cover plate 24 during manufacture and shipping and only when it is some of this is required. The earth connection therefore does not significantly increase the height of the hotplate.
  • FIG. 9 it is shown on the left-hand side that the contact surface of the head 33 can be provided with a preferably star-shaped corrugation 41. Accordingly, the sheet metal part 37 is provided on its top and bottom and the cover plate 24 (see Fig. 2 and 15), whereby the screw 32 is secured against accidental loosening.
  • the screw 32 is secured against accidental loosening.
  • the hotplate is held in the worktop opening receiving it by a bracket 42, which is supported on the underside of the worktop 17 and has a flat U-shape. Its long back is stiffened by side bends 43.
  • a cap screw 45 projects through a hole 44 in the middle of the bracket and is screwed into the internal thread in the hollow screw 32.
  • the screw 32 is a simple sheet metal stamping part and the screw 45 is a simple machine screw. So far, the hot plates were provided with bolts that were screwed into the pin 30 and which protruded far beyond the underside of the hotplate.
  • An upwardly projecting pin 47 is riveted to the bracket 42, which engages in a sleeve-like recess 46, which is integrally formed inwardly from the cover plate and thus secures the hotplate against rotation against the bracket.
  • a plurality of depressions 46 can be provided on the circumference, possibly also offset from one another by 90 °.
  • Fig. 3 shows a variant for the recess 46, which can be selected if the sheet metal from which the cover plate 24 is made should not be subjected to excessive deformation.
  • a separately produced sleeve 46 ' is tightly fastened in an opening of the cover plate 24 by a two-sided flange 46 ". It is also possible to provide the sleeve, for example in the region of the flange 46", with a pressed-in thread for subsequently screwing in a pin.
  • Fig. 4 shows in a detail that between the edge region 23 of the cover plate 24 and the lower edge 22 of the hotplate edge 21, a sealing ring 25 is interposed, which can have a flat or circular cross-sectional shape and consists of a heat-resistant sealing material. Silicone rubber, asbestos-containing sealing materials etc. are suitable for this. Further seal designs are shown in FIGS. 5 and 6, the seal 25a in FIG. 5 consisting of a paste which has been introduced into the angle between the edge region 23 and the step 25 and which, when pressed on, passes over the lower edge 22 and the inside of the edge 21 distributed. In this embodiment, the possibility of sealing in the region of the recess 26 is particularly advantageous.
  • This sealing ring can consist of a molding compound which is made from an alumina-silicate fiber and is impregnated with a varnish based on silicone resin.
  • the seal is designed to prevent moisture from penetrating into the interior 48 of the hotplate and thus possibly into the investment material 20 if the hotplate is exposed to extreme conditions, for example sea transport. Although the hotplate immediately expels any moisture that may have entered itself without generating previously unacceptable leakage currents, the seal represents an additional security.
  • the seal is made possible in particular by the cover plate resting on the lower flange. because this means that the seal comes into a lower temperature range and can be better designed. Previous cover plates were on the underside of the investment material 20. Level 25 ensures additional sealing and perfect centering.
  • edge 21 'of the hotplate body has a step-shaped recess 49 on its inner underside, so that an outer circumferential edge portion 50 of the edge 21' is formed, which extends somewhat further downward than the contact surface for the edge region 23 of the cover plate 24.
  • edge 21 'of the hotplate body has a step-shaped recess 49 on its inner underside, so that an outer circumferential edge portion 50 of the edge 21' is formed, which extends somewhat further downward than the contact surface for the edge region 23 of the cover plate 24.
  • a metal foil 51 is located approximately parallel to the cover plate in the interior 48, which is, in particular, a bare aluminum wrinkle foil. It is clamped between the edge 21 and the cover plate 24 or the seals provided (see FIGS. 4 to 7) and encloses a layer 52 between itself and the cover plate 24, which preferably consists of or contains silica gel or diatomaceous earth. This material not only ensures good insulation, but also ensures that e.g. water that has penetrated with the air humidity is absorbed in the silica gel serving as a drying agent. As a result of the automatic heating during operation of the hotplate, the drying agent is always regenerated automatically when the water is expelled, so that it always remains effective. If a desiccant is used, it may be appropriate to perforate the metal foil or to place the desiccant in other containers in the interior 48 to ensure its effectiveness.
  • the layer 52 In case of extreme conditions regarding moisture if there is no fear, it is possible to produce the layer 52 from highly heat-resistant insulating materials, for example inorganic fibers such as asbestos or other known islier materials. Together with the metal foil lying on top, a very effective insulation is formed, which further reduces the heat losses due to radiation and convection downwards, which are in any case small in the case of a contact hotplate. However, this primarily keeps the temperature of the cover plate 24 low, so that it can be installed even in the flattest cooking hobs near wooden parts in kitchen furniture.
  • highly heat-resistant insulating materials for example inorganic fibers such as asbestos or other known islier materials.
  • FIG. 10 shows three hotplates stacked one on top of the other, which apart from the fact that the sheet metal part 37 '(see also FIG. 11) is provided with a flat tongue 53 for connecting a corresponding flat connector 54 for the grounding line 40, with the hotplate according to FIG .1 are identical.
  • like reference numerals designate like parts.
  • the cut in FIG. 10 is offset by 45 ° in relation to FIG. 1, so that it can be seen that an insulating piece 55, which is supported on the inside of the cover plate 24 and extends through the cover plate 24, contains a temperature limiter in its section lying in the interior 48 and is continuous Openings 57 have (Fig.
  • the basic shape of the insulating piece 55 is elongated in the circumferential direction and it projects into Area of a bulge 60 through the cover plate.
  • the leads 58 are connected to a common connecting piece 75 is connected from a ceramic insulating material (Fig.10u.15) teck- the S or clip 76 includes for the connection of power leads 78th
  • a ceramic insulating material Fig.10u.15
  • the outer edge 77 of the connecting piece 75 is preferably a maximum of a distance of less than one hotplate radius from the outer edge and leaves adapt flexibly to the installation conditions, whereby the adjacent connection lines act like a flexible band, which allows easy swiveling and greater mobility of the connection piece in the vertical direction, but limits rotation and lateral movement to a greater extent.
  • the width of the groove is substantially greater, so that, as can be seen from Figure 10 in the two upper cooking plates than that of the iso-l ier harmonyes, the leads can be folded 58 inwards and the connection piece 77 adjacent to the insulator in the recess 61 can lie. It is also possible to store the connecting piece 77 (FIG. 10 below) folded outward approximately in one plane with the hotplate, the connecting lines 58 leading through a corresponding cutout in the packing plate 63.
  • the hotplates with their central axes are stacked one above the other with their flat cooking surfaces 13 and with their undersides covered by the cover plates 24, with only one sheet or film 62 being inserted between the cooking surfaces 13 to prevent scratches, while between the hotplates -Under a packing plate 63 is placed, which can consist of plywood or chipboard and has recesses which are selected so that the hotplate is centered on it when placed on it. Parts of the hotplate projecting downward from the outer edge 23 of the cover plate protrude into the recess 64 of the packing plate 63.
  • the hot plates 11 are offset from one another in the circumferential direction by 180 °, so that the insulating piece 55 with the connecting leads protrudes into the recess 61 and the hot plate even requires a smaller packing space than its total height.
  • the edges 21 are supported with the interposition of the packing plate 63, in that a solid stack is formed which does not tend to tip over.
  • the aligned arrangement of the hot plates also contributes to this.
  • the packing plates 63 have numerous recesses 64 side by side and one behind the other according to the desired packaging or pallet size, so that a large number of hot plates can be stored and transported in a solid block, not only saving on storage and transport costs, but also safety against accidents elevated. Packing can also be done fully automatically by grippers.
  • the silica gel filling is missing in the hot plates according to Fig. 10.
  • An aluminum wrinkle film 51 is placed parallel to the cover plate 24 for insulation purposes only.
  • FIGS. 12 to 15 Another device is shown in FIGS. 12 to 15 in order to ensure that the hotplate is secured against rotation with respect to fastening parts, for example the bracket 42.
  • a sheet metal part 65 is used, which has the shape of a flat right-angled strip which extends in the area of the bend 66. Lateral incisions 67 separate edge areas at the ends of the sections 68, which are bent or rolled up around the ends (see in particular Fig. 13), so that the ends are pin-like.
  • U-shaped cutouts 70 are provided in sections 68, so that sheet metal tabs 71 arise, which are bent out of the plane of sections 68. From Figure 14 of this sheet metal part 65 is seen in integrated e m state.
  • the anti-twist r ungs sheet metal part 65 could be provided with a third section 37 '' at the end of a flat plug tongue 53 is arranged for connection to a ground line.
  • a double function namely anti-rotation and earth connection, can be achieved with a single part.
  • the sheet metal part 37 ′ it is also possible, as shown in FIG. 15, for the sheet metal part 37 ′ to be screwed on by the screw 32 in addition to the anti-rotation sheet metal part 65. Since the part 65 is secured against rotation anyway, a corrugation 41 on it is sufficient without it being necessary on the cover plate.
  • the depression 61 lies diametrically opposite the insulating part 55. It would of course also be possible to provide an offset at a different angle. Accordingly, the recess 61 would also have to be offset from the insulating piece 55 by a different angle.
  • the end plate has the advantage that it is sufficiently rigid due to the not very deep deformation is easy to manufacture and creates a well-insulated closed interior.
  • the cover could rest on the outer edge 21 as well as on the inner edge surrounding the sensor recess with one step following the cover plate. The fastening could also be done there using banjo bolts. In this case, the pin with the internal thread would not lie centrally but, for example, in the area of the outer edge.
