Definitions

  • the invention relates to an electrical ignition device for fuel in a heating device, as well as a heater equipped therewith, as stated in the claims 1 and 14.
  • an ignition device to be operated electrically, which is provided by the generation of a hot air flow for the ignition of solid fuel, such as wood pellets.
  • a heating element in particular an electrical resistance heater is provided which has arranged in a tubular ceramic body heating elements in the form of resistance lines.
  • the ceramic support body has the required temperature resistance and insulates the electrical resistance lines with respect to electrically conductive peripheral elements.
  • the tubular heating element is inserted in a metallic hollow profile, which forms an outer flow jacket around the tubular heating element.
  • the heating element is on one of its two ends, if necessary detachable, in particular pluggable, supported in a ceramic socket. This socket also serves to make electrical contact with the electrical resistance lines with a power supply to the socket.
  • the arranged inside the metallic hollow profile, ceramic socket for the heating element causes a constriction of the free flow cross-section through the hollow profile, whereby the desired or required air flow rate is only partially achievable.
  • the positioning accuracy of the heating element with respect to the socket is hardly guaranteed. Unbalanced or unequal flow around the heating element with supply air or ambient air lead to different cooling capacities with respect to the heating element, which can cause performance problems or can lead to increased risk of damage in a particularly unevenly flow around heating element.
  • the robustness of the electromechanical socket for the heating element is only slightly satisfactory. Mechanical loads on the elongated, tubular heating element can lead to breakage of the plug-in base, which can subsequently lead to a safety impairment due to insulation faults of the plug-in base.
  • the present invention has for its object to provide an improved electrical ignition device for fuel in a heater.
  • a further object of the invention is to provide a heater which can be used as comfortably as possible with high functional reliability.
  • This object of the invention is achieved by a technically improved ignition device according to claim 1. It is advantageous that the heating element, in particular its ceramic support body, is held reliably and dimensionally stable in the hollow profile. In particular, acting vibrations or shock loads can not lead to a positional deviation of the heating element or the ceramic support body. Due to the impact-resistant fixation of the heating element in the hollow body, a proper flow around and cooling of the heating element with the air to be heated is always ensured. This possibly full or even flow around and cooling of the heating element or the ceramic support body favors its achievable life, so that a long-term functional ignition device can be achieved. In particular, gradual or shock-related deviations of the heating element from the desired position during operation of the ignition device or the heating device for solid fuels provided therewith are virtually eliminated.
  • Another advantage of the measure according to the invention is that the holder of the ceramic support body, starting from its lateral surface, the reduction of the free flow cross-section caused by this support can be reduced to a minimum.
  • the flow resistance in the air inlet section of the ignition device or the ceramic support body is kept relatively low with respect to the air to be supplied to be heated.
  • the specified ignition device provides increased protection against electrical insulation errors, after a brittle, fragile socket for releasably holding and contacting the electrical heating element is unnecessary.
  • mechanical shock loads can not cause a deviation of the heating element from the Planned position, so that a reliable function and a planned heating or ignition performance is guaranteed.
  • An advantage of this is a development according to claim 2, characterized in that the positional stability or the fixing accuracy and also the holding force of the heating element in relation to the surrounding hollow profile is further improved.
  • An expedient measure for attaching or attaching the at least one metallic holding element to the ceramic supporting body is specified in claim 3.
  • a high-strength connection between the ceramic support body and the at least one metallic support element can be established.
  • this makes it possible to dispense with mountings based on clamping forces or form-locking connections.
  • it is advantageous that such surface coatings do not reduce the cross section of the ceramic support body, so that the risk of a notch breaking effect is minimized or excluded and a high degree of robustness of the heating element is achieved.
  • a reliable or temperature-stable connection can be constructed even when using solder joints between the ceramic support body and the metallic support member.
  • excessive heating of a soldering or joining connection between the holding element and the ceramic support body is thereby held back, so that a reliable connection of the metallic support element to the ceramic support body of the heating element is ensured.
  • the measures according to claim 7 are advantageous since, in particular, when using a cylindrical hollow profile, an exact centering of the heating element in the interior of the hollow profile can be achieved.
  • the achievable with two opposing support elements stability is so high that even with external force effects the scheduled positioning of the heating element is ensured in the hollow profile.
  • a reduction of the free flow cross-section in the hollow profile can be kept low.
  • the base portion of the headband is distanced to the ceramic support body, so that the heat transfer is kept as low as possible on the outer hollow profile.
  • Another advantage of this design is that the relatively large base portion can be used for stable connection to the hollow profile and also a simple connection between headband and hollow profile is possible.
  • the headband ensure automatic centering of the heating element with respect to the outer hollow profile, so that the assembly or production cost is as low as possible.
  • the measures according to claim 13 are also advantageous since the air throughput is sufficiently strong or relatively high, even with low induced draft or negative pressure conditions.
  • one-sided heating or sections of overheating of the heating element are thereby kept in the background, whereby the functional reliability or the achievable duration of use of the ignition device is improved. This is made possible, above all, by eliminating the need for a separate holding and contacting base or by means of the specified holder of the ceramic carrier body via its lateral surface, as well as achieved by the direct electrical contacting of the resistance lines.
