Definitions

  • the invention relates to a heating device, preferably designed as a tiled stove, for generating warm air for room heating and for obtaining hot water, as is specified in the preamble of claim 1 in detail.
  • Heating devices that, like tiled stoves, serve primarily for the purpose of space heating, often develop excess heat during their operation, which can be used for other purposes.
  • a common form of use in this context is the production of hot water, which can either be consumed as such or fed into a central heating system.
  • the invention is therefore based on the object to provide a heating device of the type mentioned, which is characterized at the same time by a high efficiency in the use of the primary heat used and by a safe and reliable operation even without the installation of costly additional safety devices, in particular electrical type.
  • the overall result of the invention leads to a heating device which, with a simple structural design, combines the advantages of optimal utilization of the fuel burned in the heating chamber for generating the primary heat and operation that excludes any risk of overheating.
  • the normal case for achieving the warm air flow is mixed operation with a combination of forced circulation under fan drive and gravity, while with the fan stopped, pure gravity operation is maintained, which keeps all the warm air in motion and avoids any dangerous heat build-up.
  • full utilization of the primary heat used to generate warm air is always ensured. No separate electrical safety devices are required for this.
  • the heating device shown in the drawing has a housing 12, which is designed in the upper part externally in the form of a normal tiled stove and is additionally set up in its lower part for the production of hot water by means of excess heat.
  • the housing 12 contains a heating chamber 3, which serves as the primary heat source for the production of warm air and the production of hot water in the heating device. Gas, oil or a solid fuel can be burned in this heating chamber 3 to generate heat.
  • the flue gases generated during this combustion process leave the heating chamber 3 via a flue gas outlet 11 which emerges from the housing 12 at the top.
  • the flue gases flow successively through two heat exchangers 4 and 5, which utilize the residual heat contained in the flue gas to generate warm air.
  • a first warm air circuit I is formed in the housing 12, the air of which is heated by the heat given off by the heating chamber 3 and the heat exchangers 4 and 5.
  • This first warm air circuit I also includes a heat exchanger 1 which is arranged in the housing 12 below the heating chamber 3 and which can be fed with cold water via water lines (not shown in the drawing) and which heats up in the heat exchanger 1 by exchanging heat with the hot air in the warm air circuit I.
  • the hot water obtained in this way can be drawn off via further water pipes, likewise not shown in the drawing, this hot water either being used directly, for example, as part of a domestic water supply or being fed into a central heating system.
  • the hot air flow through the heat exchanger 1 in the warm air circuit I is generated with the aid of a blower 2, which is arranged below the heat exchanger 1 and sucks the warm air through the heat exchanger 1 and then pushes it into a circulating air duct 15 which leads upwards in the housing 12 and by means of a Butterfly valve 6 can be shut off, which is only open when the fan 2 is running.
  • the blower 2 is driven by means of an electric motor 13 underneath, the switching on of which simultaneously causes the butterfly valve 6 to open. With the fan 2 running, a closed air circuit is formed in the warm air circuit I through the heat exchanger 1 and the recirculation air duct 15 and past the heating chamber 3 and the heat exchangers 4 and 5 arranged above it.
  • the warm air of the first warm air circuit I can emit its heat to a second warm air circuit II, which is provided separately in the housing 12 and surrounds the first warm air circuit I in the housing 12 on the outside.
  • This second warm air circuit II is used to deliver hot air for heating purposes, and for this purpose it has at least one inlet 14 provided in the lower region of the housing 12 for ambient air to be heated from the surroundings and one in the upper region, in the illustrated embodiment in the ceiling of the housing 12 arranged outlet 7 for the hot air outlet into the environment.
  • the two warm air circuits I and II are separated from one another, and the air heating in the second warm air circuit II, which has no direct contact with the heating chamber 3, then takes place with heat transfer through the partitions between the two warm air circuits I and II through, the first warm air circuit I being a primary circuit and the second warm air circuit II being a secondary circuit for warm air.
  • the heat given off by the heating chamber 3 and the heat exchangers 4 and 5 to the first warm air circuit I is emitted in this operating state of the heating device partly to air in the second warm air circuit II and partly to water in the heat exchanger 1, with no place where undesirable heat accumulation can occur .
  • the heating device is responsible for this operating state, which in particular also in the event of a fault in the cold water supply to the heat exchanger 1 or in the event of a long-term interruption in the removal of hot water from the heat exchanger 1, an increased heat output from the warm air circuit I to the warm air circuit II is provided.
  • a flap system serves this purpose, which enables a direct connection of the two warm air circuits I and II and thus an inflow of warm air from the first warm air circuit I into the second warm air circuit II and entry of cold air into the first warm air circuit I.
  • this flap system includes an inlet flap 8 provided at the bottom in the housing 12 near the inlet 14 for room air to be heated in the partition between the two warm air circuits I and II for a cold air inlet also in the first warm air circuit I and one near the top in the housing 12 the outlet 7 for the hot air outlet into the environment in the partition between the warm air circuits I and II arranged outlet flap 9.
  • an operational coupling via a coupling linkage 16 indicated in the drawing by a broken line, which for a simultaneous opening and closing of both flaps 8 and 9 ensures.
  • the heating device is thus either in a combined operating state with forced circulation of the hot air in the first warm air circuit I caused by the blower 2 and gravity flow of the warm air in the second warm air circuit II or in a pure gravity operation with warm air flow alone under the influence of gravity in both the first warm air circuit I and in the second warm air circuit II. In both operating cases, it is ensured that the hot air flow obtained is sufficient to avoid undesirable heat build-up in the heating device without the need for a separate electrical safety device.
