Definitions

  • the invention relates to a closed fireplace according to the preamble of claim 1.
  • Closed fireplaces are designed in the form of fireplaces, stoves or fireplace inserts. These are used to burn solids such as wood, briquettes or the like to heat rooms.
  • such a fireplace has a door closing the combustion chamber, in the form of a pivoting or sliding door, a combustion air supply and an exhaust gas duct, each of which is operatively connected to the combustion chamber. Both the combustion air supply to supply fresh air and the exhaust gas routing are connected to the outside environment.
  • solid fuels are common for the operation of such a fireplace, which requires a corresponding storage space, which is often not available in a sufficient size.
  • the procurement of solid fuel, in particular the wood, which is preferably in the form of logs, is also complex and cumbersome.
  • the combustion of the solid fuels leads to contamination of the combustion chamber by soot deposition and ash formation, as well as sooting of a glass pane if it is present as a viewing window of the door.
  • the ash is disposed of more or less frequently, but in any case involves a corresponding amount of work.
  • the invention has for its object to develop a fireplace of the generic type so that its operation is significantly easier overall.
  • the invention results in a combination of the advantages of a fireplace operated with solid fuel and the advantages of a fireplace operated with liquid fuel.
  • the storage of fuel is much easier than that of solid fuels, in particular wood, as is the procurement of the fuel, the container holding the liquid fuel, to which, according to the invention, a burner is connected, can be replaced and refilled.
  • the storage of several such containers for storage is simple and, above all, space-saving.
  • the combustion chamber is now not contaminated or to a negligible extent. Cleaning work, such as cleaning the combustion chamber, possibly a door glass pane and ash disposal are completely eliminated, so that the operation of the fireplace is considerably simplified overall.
  • the exhaust gas generated during the combustion is removed, usually into a chimney, while the fresh air required for the combustion is obtained from the external environment according to a further concept of the invention.
  • the combustion air directly from the room, as is the case, for example, with gas-powered stoves.
  • the container holding the liquid fuel is arranged below the burner, which practically forms the bottom of the combustion chamber and is preferably covered with a combustion grate.
  • a pump is also provided in the installation space below the burner, by means of which liquid fuel is conveyed into a burner bowl of the burner.
  • Separate zones are created by means of the fuel grate, namely an early primary combustion zone below the fuel grate and a late primary combustion zone above the fuel grate.
  • a preheating / gasification zone is arranged below the early primary combustion zone.
  • the burner is ignited by a thermoelectric ignition element, alternatively by a piezoelectric ignition element.
  • the brazier is provided with an overflow which opens into the fuel tank and which has a flame retardant protection.
  • a purge air fan can be provided, with which fuel vapors are eliminated before the ignition process, this purge air fan being monitored by means of a pressure cell.
  • the fireplace above the combustion chamber can be equipped with heat exchangers, which optimize the heating effect.
  • a closed fireplace with a housing 1, in which one in the Fig. 3 recognizable combustion chamber 6 is arranged, which can be closed by means of a door 2.
  • a nozzle of a combustion air supply 4 is arranged in the lower end region, via which room air is supplied to the combustion chamber 6 as combustion air.
  • a fresh air line which is connected to the outside air, can optionally be connected to the combustion air supply 4.
  • Convection air is guided into the housing 1 via air slots 5, which are arranged in the area adjacent to the combustion air supply 4 in the housing 1.
  • an exhaust gas duct 3 is operatively connected to the combustion chamber 6, the exhaust gas duct 3 being connected to the outside air in any case, for example connected to a chimney.
  • a burner 7 is arranged, which as a detail in the Fig. 5 is shown.
  • a container 8 for a liquid fuel for example alcohol such as ethanol or the like, is positioned below the burner 7 in the housing 1.
  • the liquid fuel can be fed to the burner 7 via a pump 10.
  • a blower 9 fuel vapors that have accumulated in the feed line to the burner 7 are to be removed before ignition, wherein the blower 9 can be monitored by means of a pressure cell.
  • heat exchangers 17 are arranged above the combustion chamber 6, in order to increase the heating efficiency.
  • a brazier 11 is formed, which is divided into two superimposed zones by a firing grid 12, namely into a lower early primary combustion zone 14 and an upper late primary combustion zone 16, an igniter 13 being assigned to the later primary combustion zone 16.
  • a preheating / gasification zone 15 is arranged below the early primary combustion zone 14.
  • the burner 7 is also in the Fig. 4 recognizable, which shows a top view of the fuel grille 12 and the igniter 13.
  • the container 8 can moreover be removed from the housing 1, a flap preferably being provided for this purpose in the housing 1.
  • a flap preferably being provided for this purpose in the housing 1.
  • one or more containers 8 can be deposited, these being interchangeable with refilled containers 8 when emptied.
