Definitions

  • the invention relates to a heater for heating a heat transfer medium for heating a building or for providing hot water based on the combustion of a fuel.
  • this intake pipe Like all fixed-size intake pipes, this intake pipe also has the disadvantage of exhibiting its best effect in a restricted range of operating parameters. Therefore, in each case sets of several intake pipes are usually kept ready for certain heaters, with which the intake system can be acoustically adjusted by replacing the intake pipe according to the boundary conditions. In addition, the intake pipe is basically to be provided as an additional component and increases the complexity and cost of the heater.
  • the intake system has a split outer housing in which a cavity is provided.
  • this cavity can be configured with air guide elements, a flow channel.
  • the outer housing is made of foam material, preferably EPP.
  • the air guiding elements are made of foam material, preferably of EPP.
  • the intake system outer housing is integrally formed with a fixation for at least one unit of the heating system or connected with such a fixation, in the fixation of an assembly can be inserted in a form-fitting manner and thus fixed, without being screwed, for example, with the recording.
  • a heater is described with insulating means in which the individual units of the heater are inserted so that the units are positively fixed by the insulating means.
  • the intake system is formed directly by the insulating means, wherein the insulating means is the outer casing of the intake system, which encloses the cavity.
  • the inserted units are at least the fuel gas-air mixing device and / or the fan for supplying the combustion air to the burner.
  • the intake system is designed so that the heat loss of the pump is used to promote a heat transfer medium for preheating the combustion air by being passed past the pump and so absorbs the heat loss.
  • the air guide elements can be positively inserted into the cavity, clamped non-positively or materially connected by gluing or welding.
  • FIG. 1 represents an inventive extraction system with open and FIG. 2 with closed outer housing.
  • the suction system consists of a suction system outer housing 7, which is made in two parts and is divided by a parting line 14.
  • the exhaust system outer housing 7 has a cavity 9, which forms a flow channel 8.
  • the flow channel 8 is not completely provided in the parting plane. According to the invention it is sufficient if a part of the cavity 9 is located in the parting plane in order there to air guiding elements 15 (in FIG. 3 shown) to bring.
  • the fuel gas-air mixing device 4 and the blower 3 are fixed.
  • the intake system outer housing 7 fixings 16, for example in the form of pockets, recesses or holders, in which the units are fixed in a form-fitting manner.
  • the intake system outer housing 7 must sealingly surround the fuel gas / air mixing device 4 in the region of the air inlet, in order to ensure an exclusive air flow through the cavity 9 or the flow channel 8.
  • FIGS. 3 to 5 how according to the invention in the cavity 9 of the intake system outer housing 7 of the flow channel 8 is formed.
  • the intake system outer housing 7 provides receptacles 10 with which the air guiding elements 15 can be fastened in the cavity 9.
  • This can, as in the example in FIG. 3 shown, form-fitting. It is also possible to frictionally clamp the air guide elements 15 between the housing halves of the intake system outer housing 7 or to join them by adhesive bonding or welding.
  • FIGS. 4 and 5 show two variants in which with air guide elements 15 in the cavity 9, a flow channel 8 is formed. The illustration corresponds to a plan view of FIG FIG. 1 shown variant. Between the housing halves of the intake system outer housing, a G-shaped cavity 9 is formed.
  • a short flow channel 8 is formed.
  • air guide elements 15 a meandering flow channel 8, which is longer.
  • FIG. 6 represents a heater according to the invention with the intake system 6 according to the invention.
  • this heater units such as the burner 5 and the pump 17, with a heated by the burner 5 heat transfer medium is circulated, fixed in form-locking fixations of the insulation 11.
  • heat transfer medium is circulated, fixed in form-locking fixations of the insulation 11.
  • FIG. 1 directed.
  • blower-assisted heaters have a vacuum chamber which is formed by the fact that the outside air is not supplied directly to the blower 3, but is first conducted into the interior of the housing and is then sucked in by the blower 3. Thereby, a negative pressure in the entire housing 2 of the heater 1 is ensured, so that no gas can escape from the heater 1 to the outside.
  • the air is passed through an air supply 19 through a channel in the insulation 11 into the heater 1 enclosed by the housing 2.
  • the air flows through channels 18, the pump 17 and absorbs their heat loss.
  • the air flows due to the through the Blower 3 produced pressure gradient through the flow channel 8 in the intake system outer housing in the manner described above by the fuel gas-air mixing device 4, where it is mixed with fuel gas, and by the blower 3 in the burner 5.
  • the intake system outer housing 7 be integral with the insulation 11, be directly connected to this or be indirectly connected via brackets with this.
  • FIG. 7 put that in FIG. 4 described intake system in which an additional damper 12 is provided.
  • This damper 12 may be made of a porous material, a flow or a sintered body.
  • the occurrence of self-excited vibrations in the intake system 6 is damped by the damper 12.
