Definitions

  • the invention relates to electric radiant heaters, in particular for glass ceramic plates with a support body made of an electrically and heat-insulating material with grooves into which helical heating resistors are inserted.
  • the object of the invention is therefore to propose a radiant heater and method and device for its production, with which a secure fixing with little effort and without additional tools such as kit, .Cement or the like. is possible.
  • the determination can be made by pressing the heating coils into grooves in a shaped body, which have a small undersize compared to the heating coils.
  • the heating coils are pressed slightly into the groove side walls (possibly with a slight deformation of the heating coil cross section) and thus securely fixed.
  • An indentation into the base of the groove, in particular in the projections provided there, is also possible.
  • heating coils when inserting the heating coils into suitable grooves, to deform the heating coils, for example from a circular into an oval cross section, by pressing from above, the narrow ones Press the sides of the resulting oval into the groove side walls. It is also possible, after inserting the heating coils into suitable grooves, to press the webs provided between the grooves, ie in the area of the groove side walls somewhat above the coils, in such a way that a section overlapping the heating coils is produced. The heating coils can also be pressed into the groove side wall.
  • the pressing can be carried out both in the fully cured state of the carrier body, which consists of an insulating ceramic or fibrous material.
  • the carrier body which consists of an insulating ceramic or fibrous material.
  • the heating coils can be pressed in with very little resistance, so that the process can also be used for the thinnest heating coils.
  • Fig. 1 shows a radiant heater 11 which is arranged below a glass ceramic plate 12 which forms the cooking surface of a cooking appliance.
  • the radiant heater 11 is supported by springs 14 on a support structure 13, which may consist, for example, of a sheet metal recess. It serves to heat cooking vessels placed on the glass-ceramic plate 12, by means of radiation, which can penetrate part of the glass-ceramic plate and, on the other hand, heat it.
  • the radiant heater 11 consists of a normally. circular flat carrier shell 15 made of sheet metal, in which a carrier body 16 made of an electrically and thermally insulating material is introduced. It can consist of a ceramic or inorganic insulating material be made.
  • the carrier body 16 also has the shape of a flat circular shell with a substantially flat bottom 18 and a raised edge 17 which is pressed against the underside of the glass ceramic plate 12 under the action of the springs 14.
  • the carrier body 16 has spirally arranged grooves 19 in which electrical heating resistors in the form of heating coils 20 are located. Their arrangement and fastening in the grooves can be seen more clearly from the following drawing figures.
  • the heating resistors are connected to a domestic electrical network via a switch or controller.
  • FIG. 2 shows in detail the arrangement of the heating coils 20 in the grooves.
  • a heating coil with a circular coil cross section is introduced into a groove whose width corresponds to the outside diameter of the coil, while the depth is less than the coil diameter.
  • a elevations 31 are arranged centrally, which can either consist of a rib running in the longitudinal direction of the groove or of individual projections on the groove bottom.
  • the heating coils are now pressed into the groove in such a way that they rest on the groove side walls and are thus well guided laterally, but penetrate into the elevations 31. As a result, the heating coil is held in the lower area, in particular against displacements in the longitudinal direction of the groove and coil.
  • the elevations are thus deformed in such a way that a toothing is created between them and the heating coil.
  • the carrier body 16a deforms in the region of the elevations in such a way that a securing against falling out upwards also arises, which is advantageous but not as important as the fixing in the longitudinal direction.
  • the embodiment of Figure 3 has grooves 19 b, which are slightly narrower than the outer diameter of the heating coils.
  • the groove bottom 22 b is flat.
  • the heating coils 20 When the heating coils 20 are pressed in, they press laterally into the groove side walls 21b, so that indentations 23 are formed there, which in turn bring about a particularly good fixing in the longitudinal direction of the groove.
  • the depth of the groove is again less than the outer diameter of the coil, so that the upper coil section protrudes on the support body 16 b, which results in good radiation conditions in this area.
  • the groove is preferably somewhat deeper than half the diameter of the heating coil, so that the widest point of the heating coil is still in the region of the indentations 23.
  • the carrier body 16 c is shown in a further embodiment after the heating coils 20 have been inserted, but before their final fixing.
  • a groove 19 c the width of which corresponds to the outer diameter of the heating coils 20, which have a circular cross section when inserted, and whose depth is between half and full coil diameter, the heating coils are laid. Thereafter, the heating coils are acted on with a tool 24, which has the shape of a plate with downwardly projecting, in the exemplary embodiment triangularly shaped ribs 25 which extend in the longitudinal direction centrally over the grooves 19c.
  • k ommen characterized the heating coils, a shape corresponding to a lying, rounded B, said lying on the open groove side outer spiral portion 26 of the deformed heating coils 20 c has an indentation.
  • the overall shape of the coil is widened, so that it digs into the side walls 21 of the groove 19 c and forms indentations 23 c there, which, as in the embodiment according to FIG. 3, ensure the fixing of the heating coils.
  • ribs of any desired basic shape can be used, so that the helix which is most favorable in terms of the definition and the radiation properties is obtained Have shapes made, for example a flat oval.
  • the inflection in section 26, however, has the advantage that a larger section of the heating coils is located on the upper side directly facing the glass ceramic plate.
  • a carrier body 16 d is also shown before its completion.
  • the grooves 19 d correspond to those according to FIG. 4, however the carrier body 16 d in FIG. 6 is formed from the ceramic or fiber-like mass, but has not yet been dried or fired, as a result of which it obtains its final hardness.
  • the heating coils 20 are suitable, but without indentations in the grooves 19 d.
  • FIG. 7 shows the same carrier body 16 d after drying or firing.
  • a shrinkage occurs in the material of the carrier body, i.e. the carrier body shrinks.
  • grooves 19 d according to Figure 6 reduced in their dimensions to those of the groove 19 d 'according to Figure 7.
  • the dimensions of the heating coils which are not influenced by the hardening, are therefore pressed into the side walls 21 d of the grooves and form impressions 23 d there, which have the same effect as in FIGS. 3 and 5.
  • small deformations of the heating coils as a result of the lateral indentation which, however, can be prevented, in particular in FIG.
  • FIG. 8 also shows a manufacturing stage of a carrier body 16 e, in which the grooves 19 e are substantially wider than they are deep, so that heating coils 20 e with a flat oval coil cross section could largely be inserted therein.
  • a tool 27 which has triangular projections 28 on its underside, but which are arranged centrally above the webs 90, is inserted into these webs 29 acts so that apart in the manner of a rivet head 30 (Fig.9) and thus define the heating coils 20 e, which remain essentially unchanged in shape.
  • the rivet head-like deformations 30 form a particularly good safeguard against the heating coils 20 e falling out.
  • the deformation between FIGS. 8 and 9 can follow in the already hardened or wet state, the shrinkage in the latter case (method according to FIGS. 6 and 7) helping to determine it.
  • the fixing methods according to the individual described embodiments are particularly advantageous in their combination, especially when it comes to fixing very thin wires, which are also particularly critical with regard to creep.
  • the fixing can be carried out with fewer fuses; in this case, for example, the partitions between the grooves can also be partially omitted or only partially present. This improves the heat transfer conditions.
  • the depth of the indentations of the heating coils in the walls of the groove consisting of the side and bottom walls depend on the winding diameter of the wire load and the specific load on the heated surface and the wire thickness.
  • the heating coils are also protected against falling over. This could occur if the wire forming the heating coils loses so much strength at high temperatures that the individual turns of the coils fall laterally onto one another unless they are supported.
  • the type of shaped body will also have to be taken into account. So you become, for example, with impressions
  • the types of fixing made prefer a relatively soft molded body made of fibrous material, while in the embodiment according to FIGS. 6 and 7 a ceramic material that is hard after firing is primarily suitable.
  • the heating coils can also be introduced into the carrier body, which has been pre-dried or pre-hardened but has not yet been fully heard.
