Definitions

  • the invention a heater, in particular a vehicle heater, which has a burner component which projects into a combustion chamber delimited by a combustion tube, and which is accommodated in a surrounding burner head housing of the heater according to the preamble of claim 1.
  • the combustion air which is from a combustion air fan of the Heating device is delivered, enters a combustion air space of a predetermined volume, which is formed between the outer surface of the burner component and an inner surface of a jacket part surrounding it.
  • the burner component surrounding the flame root, the jacket part surrounding this and a burner head housing part accommodating both are fitted together as sheet metal parts.
  • a high degree of manufacturing accuracy is required for a perfect, tight fit of the parts. If the parts are tightly seated for leak tightness, later disassembly is necessary, e.g. Gaining access to the combustion chamber during maintenance work is only possible with great effort.
  • a heater in particular a vehicle heater with a burner component is described, which can be pressed in the axial direction in the direction of the combustion tube by means of a pressing device for fixing the position.
  • the pressing device presses the burner component against correspondingly defined conditions of the burner head housing part, the burner head housing part on the one hand and the outer surface of the Burner part, on the other hand, delimits the space into which combustion air coming from a combustion air blower enters and then enters the burner component.
  • There is direct contact between the burner head housing part and the burner component so that heat transfer to the burner component via the burner head housing part is also possible via these system contacts, in which the exhaust gas outlet of the heater is also provided.
  • the invention has for its object to provide a heater, the structure of which enables reliable, tight assembly of the components involved with simple means.
  • the jacket part can also be designed such that other burner devices, such as flame monitors, ignition devices and the like. are carried by the burner jacket part.
  • the outer surface of the jacket part rests on the inner surface of the burner head housing part, whereby thermal decoupling is achieved by means of the air gap between the burner part and the jacket part, through which combustion air flows, so that the burner head housing part is not in direct heat-conducting connection with the burner component .
  • the burner can thus be largely free of temperature influences through the burner head housing part operated, which enables low-pollutant combustion.
  • the combustion air space is preferably delimited on the end face by a cover which cooperates with the burner component and which seals the combustion air space on the end face from the surroundings.
  • a cover which cooperates with the burner component and which seals the combustion air space on the end face from the surroundings.
  • an inlet opening for the combustion air coming from the combustion air fan can be provided, via which the combustion air is introduced into the combustion air space.
  • This opening is preferably also sealed off from the surroundings by means of a sealing ring.
  • the combustion air is introduced into the combustion air space in a predetermined flow direction, so that the combustion air supply is as low-loss as possible.
  • the energy requirement of the combustion air fan is favorably influenced in the sense of a reduction.
  • the combustion air is preferably introduced into the combustion air space via the inlet opening in such a way that the combustion air is directed onto the outer surface of the burner part.
  • a section of a total of 1 heater is shown.
  • a burner tube 3 is arranged coaxially to the longitudinal center axis 4 of the heater 1.
  • the combustion tube 3 delimits a combustion chamber 5.
  • the combustion tube 3 is surrounded by a heat exchanger 6, which in turn is enclosed by the housing part 2.
  • a so-called "water heater” is illustrated which works with a liquid heat transfer medium which flows through the space between the heat exchanger 6 and the housing part 2.
  • the hot combustion gases generated in the combustion chamber 5 give off their heat to the liquid heat transfer medium, which is thereby heated and is used in the intended use for vehicle heating.
  • the hot combustion gases leave the heater 1 through an exhaust gas outlet 7.
  • the inlet area with the inlet and the outlet area with the outlet for the heat transfer medium are not shown in the drawing, since they are not in the plane of the drawing.
  • a burner component which represents the actual flame producing burner, and in which an ignition device 11, for example a glow plug, and a Flame detector 12 protrudes.
  • a so-called evaporation burner is selected as the combustion design, which comprises an absorbent body 13 which is arranged upstream of the ignition device 11 in the burner component 10 and which serves to evaporate the preferably liquid fuel supplied.
  • a jacket part generally designated 14 surrounds the burner component 10 and is arranged concentrically to it in such a way that a combustion air space 15 is formed between the burner component 10 and the jacket part 14, which is designed in the form of an annular gap.
  • this combustion air space 15 is delimited by a cover 16, which is tightly connected to the burner head housing part 2a.
  • this cover 16 there is an inlet opening 17 which is connected to an outlet (not shown) of a combustion air blower (also not shown).
  • a seal 18, which is designed in the form of a sealing ring 19, is inserted into the inlet opening 17 for sealing off from the surroundings.
  • combustion air is introduced into the combustion air space 15 with low losses by the combustion air fan in such a way that the combustion air flow is directed onto the outer surface of the burner component 10.
  • Openings 20 are provided in a distributed arrangement over the circumference of the burner component 10, through which openings the combustion air is introduced into the interior of the burner component 10.
  • a further opening 21 is provided on the burner component 10 in the vicinity of the ignition device 11 in order to introduce combustion air into the space 22 around the ignition device, which is further delimited by a carrier 23 for the absorbent body 13.
  • the jacket part designated overall by 14, is divided in the radial direction, so that matching parts 14a, 14b are obtained.
  • the division plane 24 is inclined to the outer surface 25 of the outer part 14 and a device 26 is provided. by means of which the parts 14a, 14b of the jacket part 14 can be braced against one another in order to achieve a tight seal in the region of the parting plane 24.
  • the part 14a of the jacket part 14 also serves as a carrier for the flame detector 12, while the other part 14b thereof, which faces the cover 16, receives the ignition device 11.
  • the casing part 14 as a whole or at least a part 14a, 14b of the casing part 14 is made of a light metal or a light metal alloy, such as made of aluminum or an aluminum alloy. In this way, the weight for the additionally provided jacket part 14 can be reduced.
  • the jacket part 14 expediently lies at least partially on the inner surface of the burner head housing part 2a and is supported by the latter.
  • an annular space serving as the combustion air space is formed around the burner component 10, the volume of which, in order to optimize the combustion properties of the burner, to the desired design of the heater and the like. can be coordinated. Furthermore, can be chosen by the predetermined air volume, which is largely independent of the size and shape of the burner head housing part 2a, so that vibrating air volumes are avoided. This results in a low-noise operation of the burner and the heater 1 as a whole. Furthermore, the jacket part 14 enables a thermal decoupling of the housing part 2 and the burner head housing part 2a, so that the burner is largely free of temperature influences of the housing part 2.
  • the present invention is not limited to the details of the above-described embodiment, but the jacket part 14 can also be configured differently, provided that the aim of the invention of the predetermined volume of the combustion air space around the burner component 10 is achieved.
