Definitions

  • This invention relates to a heating appliance and concerns a heating appliance having a gas burner, and a control valve disposed in front of the inlet of the gas burner and operable to control the burner output by means of an on/off switching operation and by regulating the gas supply to the gas burner during the gas supply phases thereby to provide for a pulse-duration modulated gas proportioning and burner output.
  • Such a heating appliance is known from the DE-OS 23 08 641, the gas burner described there being intended in particular for cookers, but it renders it possible, with a regulated on/off control in adjustable pulse-duration modulation, to adjust the heating energy continuously over a wide range, at any rate with regard to its average value.
  • the heating appliance is constructed in the form of a heat radiator with at least one radiator tube extending in alignment with the mouth of the gas burner and a fan disposed on the radiator tube at the end, and in that the radiator tube is of strong-walled construction with a weight of more than 2.5 g/crn2 relative to its generated surface.
  • the heating appliance of the type designated at the beginning is provided with a shape in the form of a heat radiator and so achieves an extremely efficient low-loss method of operation.
  • the radiator tube renders it possible, by radiation, to heat regions which are scarcely accessible with other means of heat transmission.
  • the exhaust gases of the burner enter the ambient air with a heating effect.
  • radiator tubes of a conventional type are conventionally of thin- walled construction with a view to saving material, saving weight and providing for rapid heating up.
  • the radiator tube in the heating appliance according to this invention is made thick-walled with a weight of more than 2.5 g/cm 2 of generated surface of the tube. The mass incorporated in this case ensures that, in switching operation, the radiator maintains its temperature to such an extent that no noticeable fluctuations in radiation occur but instead a constant comfortable feeling of warmth develops in work places where such radiators are typically mounted.
  • the temperature of the radiator tube can be kept low, for example in a range of less than 300°C, in which case a radiation of less than 6 mW per gram results in relation to the mass of the radiator tube.
  • the phases of switching on and off can be extended to several minutes.
  • each switching on has to be preceded by a scavenging operation which removes any explosive gas which may have remained behind in the radiator tube, before renewed ignition.
  • a scavenging operation to be fixed at 20 seconds for example, then determines the order of magnitude in time of the following switching on and off cycles.
  • the heating appliance designated as a whole by 1, has a radiation tube which consists of two tube portions 2, 3 extending parallel to one another, and a return bend 4 connecting these two tube portions 2, 3.
  • the radiation tube is connected to a box-like reflector 5 at both ends via welded-on struts 6, 7, 8, 9 and stiffened at the same time.
  • the radiator tube formed in U-shape with the tube portions 2, 3 and the return bend 4, has two ends which are situated close beside one another, in front of one of which there is disposed a gas burner 10 with a magnetically operated valve 11 (and associated control).
  • An exhaust-gas fan 12 is disposed in front of the other end of the tube , formed by the tube portion 3.
  • the heating appliance 1 can be disposed as a whole over a place for a worker or another region to be heated, particularly in a large or open space, and the appliance ensures an effective localized radiation heating after the necessary gas and current connections have been installed.
  • the mode of operation of the appliance 1 is as follows:
