Definitions

  • the invention relates to a heater or radiator, in particular for kitchen appliances, as e.g. can be used as a radiant heater or other radiator for heating a hotplate, an oven muffle or other.
  • a radiant heater or other radiator for heating a hotplate, an oven muffle or other.
  • Such radiators usually form a self-contained unit, which as such can then be attached to the corresponding device, e.g. a hob, a muffle wall or the like is to be attached.
  • a heating side of the radiator then forms the correspondingly large-area output for the thermal output of the radiator.
  • Resistors such as heating resistors, series resistors or similar components, can be provided in a plane which is approximately parallel or set back from the plane of the thermal output.
  • the respective resistor is expediently assigned insulation which can simultaneously form the only support for mechanically holding one or all of the resistors and expediently has a continuous surface area which is approximately in the order of magnitude of the thermal output, for which purpose a particularly flat or only a few millimeters thick insulation is suitable.
  • the insulation is primarily electrically insulating and can also be thermally insulating, but does not have to be impermeable to visible thermal radiation, for example infrared radiation, at least in the region of the intervention of the respective resistor. At least in these areas, the insulation can also be designed such that as much heat or at least the majority of it is dissipated from the engaging section of the resistor not only in the first phase of commissioning, but also in continuous operation, as from the non-engaging section.
  • An insulation e.g. Resisting against lifting is relatively difficult to secure from a slurry poured into the form of mineral fiber, granules, binders or the like. It is then pressed into shape and then dried or hardened, while securing against lateral movements by engaging in depressions or between protrusions of the insulation is less difficult.
  • Fastening elements can be used for securing against lifting, which can be formed in one piece with the resistor in the form of staples, adhesive spots or similar separate components or in the form of angled projections and are both connected to the resistor and engage in the insulation.
  • fastening elements In the case of flat resistors in particular, such fastening elements then form resistance-inactive components insofar as they do not contribute to the electrical resistance value, namely rather in the manner of blind branches, the current does not flow through them, or the flow through them is only significantly reduced compared to the sections with maximum flow density.
  • These fasteners increase in the case of certain training the complexity and possibly not negligible the weight of the radiator and are essentially only heated by heat conduction or radiation from the resistive areas of the heating resistor, but not by their own resistance work.
  • Round wire resistance coils on the other hand, can be embedded tightly enclosed in the insulation with resistance-active fastening sections.
  • flat resistors which are attached to the insulation at least partially lying or completely embedded between insulation layers, for example as a non-inherently stable vapor-deposited layer.
  • flat resistors whose resistance-active cross-sections are at least partially not parallel to the heating side or heating level, but instead inclined to right-angled, have significant advantages because they require less space even with high resistance power across their longitudinal direction and approximately parallel to the heating level and therefore in higher power density and can be better insulated against leakage currents. Securing against lifting is, however, more difficult and more complex for the reasons mentioned above.
  • the invention is furthermore based on the object of creating a radiator with which disadvantages of known designs or disadvantages of the type described can be avoided.
  • a resistor with flat cross sections in the area or outside of these cross sections should be secured in a simple manner on the insulation, in particular against being lifted off, even if at least parts of the respective flat cross section lie transversely to the heating plane.
  • thermal overloads of the insulation should be avoided and / or as many conductive or metal members as possible that are electrically conductive with the resistor are connected to be involved in the electrical resistance work.
  • means are provided by means of which the respective resistance is secured against lifting off by the direct engagement connection of a resistance-active area with the insulation.
  • the resistance expediently has at least one elongated longitudinal section with full flat cross sections in the region of this fastening section and / or subsequent to or in the longitudinal distance from this fastening section, which are at least partially transverse to the heating plane.
  • the respective fastening section or the resistor can be used have only resistance-active cross-sections over its entire one-part longitudinal extent. Furthermore, the overall height of the insulation, of the resistor and of the entire radiator can be reduced, in particular, if the said longitudinal edge surface of essentially all of the longitudinal sections of the resistor lies essentially in a single plane.
  • the central longitudinal axis of all fastening sections or all longitudinal sections can be provided in a single plane, through which the heating plane can be defined.
  • the heating resistor for securing against lateral movements parallel to the heating plane is also advantageously supported directly over the surface of the insulation, its two side surfaces being able to bear closely against approximately parallel supporting surfaces of the insulation, essentially under all operating conditions, at approximately the same or different heights. In contrast to a support only in the area of a sharp edge of an edge surface and not also at a distance from this edge surface, very good lateral support is achieved as a result.
  • the resistance can also be well secured against movements to the core of the insulation if it is supported on the insulation over at least half of its length or its entire length with the associated edge surface at least in one operating state. Is the respective mounting section spring back z. B. biased in that it engages approximately parallel to the heating plane curved in the insulation, so an additional securing jamming against the insulation takes place by the expanding and / or narrowing spring force.
  • the respective fastening section or the entire resistor is formed by a flat wire or a flat strip, the respective longitudinal edge of which is approximately straight in the stretched, that is to say the longest, state and / or the lateral surfaces of which are also free of any projections or openings can.
  • the material thickness of the flat cross section can be well below half a millimeter and, depending on the requirements, can be any integer multiple of a tenth of a millimeter or a hundredth of a millimeter, for example seven hundredths of a millimeter.
  • the material width or height of the flat cross section is expediently several millimeters, in particular less than 10 or 5 mm, and can vary according to the requirements in these areas, each integer multiple of a half and / or a millimeter, for example 3 mm.
  • the greatest depth of engagement of this flat cross-section in the insulation is expediently at least a quarter of the material width or the width between the edge surfaces and at most a fraction more than this width, the depth of penetration being, depending on the requirements, each integer multiple of half a millimeter and / or one millimeter can.
  • the insulation is at least partially designed as a light guide and / or on at least one surface as a light exit window within its cross sections and is thus connected to at least one light source.
  • the light source can be in a simple manner the resistor which emits infrared radiation during operation, which is arranged, for example, over a large area or approximately uniformly distributed over the insulation and whose radiation then propagates over a large area within the insulation and also emerges to the heating side.
  • the entire insulation can be used in whole or in part as a light plate, which can be recognized by the covering, translucent and / or transparent cover plate made of glass ceramic or the like as an indication of the operating state.
  • the light guide and / or the light exit function can be changed so that certain desired patterns are achieved.
  • No opacifying agent can be provided in light-guiding areas or areas provided for the light exit, but this can be replaced by a translucent admixture, for example quartz powder, or another grain size.
  • the remaining components of the insulation are expediently light colored to white and / or translucent in these areas.
  • the radiator 1 has an essentially dimensionally stable, multi-part and cup-shaped base body 2, the cup opening of which is essentially completely thermal Output forms.
  • the largest material volume of the base body 2 forms an essentially two-part or three-part insulation 3 consisting of a supporting body 4 and an insulating body 5.
  • the supporting body 4 has, in particular, electrically insulating properties and forms the essentially flat and / or smooth bowl bottom which is exposed for thermal output .
  • the support body 4 is supported flat on an approximately plate-shaped insulating body 5, which have better thermal insulating properties than the support body 4 and can only rest on this in the edge and / or at least one ring area, so that a large area between the two bodies 4, 5 Gap gap exists.
  • the mechanical strengths, such as compressive, bending, tensile and / or shear strength of the insulating body 5 can be lower than those of the supporting body 4, and both are arranged in a socket 6 made of material of a higher strength, for example in a sheet metal shell, which the insulation 3 secures axially and / or radially essentially without play.
  • a ring-shaped continuous edge 8 which forms the cup opening and is made of insulating material which, according to FIG. 1, is formed in one piece with the supporting body 4 and consists of an insulating material which corresponds to that of the supporting body 4 and / or the insulating body 5 is similar.
  • This edge 8 the radial thickness of which is greater than the thickness of the supporting body 4, is closely surrounded by a jacket-shaped edge 9 of the holder 6, which here projects axially beyond the free end face of the edge 8, but does not lie directly against the cover plate in the installed state, e.g. by an insulating ring placed on the edge 8, which protrudes over the edge 9.
  • resistors 10 are fastened so that they are parallel to movements against Floor 7 or to their longitudinal direction or against lifting movements transversely from the floor 7 are secured substantially free of play.
  • the resistors 10 are preferably distributed substantially uniformly over a field which approximately adjoins the inner circumference of the edge 8 over the entire circumference and extends to the center of the base 7.
  • Each resistor 10 has exactly the same, approximately rectangular, flat cross-sections throughout its entire length in that it is made from a flat strip that is not processed in a cutting manner or with the removal of material parts in order to produce the heating resistor.
  • the flat strip is only deformed in a bending manner. It has two side surfaces 12, 13 which are parallel in cross-section and two very narrow edge surfaces 14, 15 connecting them, its thickness 29, for. B. about 0.07 mm and its largest cross-sectional width or width 28 z. B. can be about 3 mm.
  • the respective band end of the resistor 10 can be formed directly and without additional intermediate members as an electrical connection end 16 and can be brought into a position by bending or interleaving with the rest of the resistor 10, in which it is contact-free with respect to the insulation 3 and is particularly suitable for the electrical connection well suited.
  • a one-piece, continuous flat strip can also form two mutually adjacent, separately switchable resistors, if these at one end merge into one another via a cross section and / or these individual resistors connecting cross section is integrally formed with a corresponding connection end.
  • the respective resistor 10 forms a fastening section 17 which is continuous over most of its length or its entire length by virtue of the fact that it is continuously in engagement with the support body 4 over this length in such a way that it is secured against movement in the directions mentioned is.
  • an engagement section 18 adjoining an edge surface 14 in the form of a strip is continuously embedded in a corresponding groove-shaped depression 19 of the supporting body 4.
  • the flat cross section 11 continuously forms resistance-active cross sections between the two edge surfaces 14, 15, which is why the engagement section 18 is also resistant to the same extent as the sections of the flat cross section 11 projecting freely above the bottom 7.
  • the depth of engagement of the engaging portion 18 may e.g. about 2 mm or two thirds of the total width of the flat band.
  • the two side surfaces 12, 13 can rest in the area of the respective common longitudinal section at different heights on the insulating material of the support body 4 or at the same height, depending on which radiation conditions or coupling effects are to be achieved.

  • the resistors 10 are located on the heating side 20 of the base 7 or the base body 2 facing the cup opening and, for example, with their edge surfaces 15 closer to the thermal output, determine a heating plane approximately parallel to the base 7 21.
  • the radiator 1 has a central axis 22, which is perpendicular to this heating plane 21 and about which the resistors 10 are curved.
  • each resistor 10 has a course which changes in its longitudinal direction, for example a sinusoidal curve, in that, in view of the heating plane 21, it is alternately provided with opposite, but essentially the same curvatures 23 and adjacent curvatures with their approximately straight or planar legs 24 merge into one piece.
  • the engagement section 18 and the groove-shaped recess 19 are curved permanently or intrinsically stiff, the legs 24 diverge from the respective curvature 23, expediently at an angle of more than 30 °, 60 ° or 90 °.
  • thermal elongations of the resistor are transmitted to the supporting body 4 in a relatively unproblematic manner, namely mainly in the longitudinal direction of the depression 19.
  • the fastening section can also be biased in the longitudinal direction by stretching and / or compressing the corrugation or the resistance 10 in individual partial or all longitudinal sections, so that it resiliently rests with tension on corresponding transverse flanks of one or both side surfaces of the recess 19.
  • the two legs 24 of a wave arc can each form a correspondingly narrowed or widened pretensioned clamp, which rests with the prestress on the associated side surface of the recess 19. At least in the area of these side surfaces, the support body 4 is resiliently resilient under these tensioning forces, so that there is a very secure clawing of the resistor 10. In contrast, the compressive strength of the material of the resistor 10 is significantly higher.
  • the free end face 25 of the edge 8 projects a small amount beyond the end face of the edge 9, so that a radiation-permeable cover plate 26 made of glass ceramic or the like is prestressed with its flat back or underside under pressure on this end face 25 can concern.

  • the respective heating resistor or separate heating resistors can protrude freely to different degrees from the bottom 7 to the heating side 20, engage in the support body 4 at different depths, have different bandwidths and / or different strip thicknesses, as a result of which areas of the heating field with different power density or different sensitivity the heating effect and the glowing can be created.
  • the corrugated resistance can be pressed into the dry prefabricated or still moist-formable support body 4 without prior production of the recess 19.
  • the insulating material diverts in a compressive manner, after which it springs back or flows back against the engagement section 18, so that the resistor 10 then prevents it from being lifted off from the floor 7 is secured very positively.
  • the resistance 10 can be pressed in until its edge surface 14 or the fastening projections on the insulating body 5 and / or until the edge surface 14 stops on the support body 4.
