Definitions

  • ABSTRACT An open fireplace for living quarters embodying a firebox, rear wall and flue or chimney as well as an air guiding system accommodated in the walls for entrapping or catching fresh air at a catch location arranged externally of the room and for heating this fresh air in at least one downdraft channel exposed to the thermal action of the firebox, the air infeed location of which is disposed at a higher location than its air outfeed location.
  • At the air outfeed location of the at least one downdraft channel there is provided at least one updraft channel having an air outfeed location which opens into the room or the like.
  • the present invention relates to a new and improved construction of open fireplace for living areas or quarters encompassing a firebox, side walls, rear wall and flue or chimney as well an air guide system accommodated in the walls for catching fresh air at a catch or entrapment location arranged externally of the area or room and for heating this fresh air in at least one downdraft channel subjected to the thermal action of the firebox, and the air infeed location of which downdraft channel is higher situated than its air outlet or outfeed location.
  • the guiding of the air of the initially discussed fireplace differs from this just mentioned guiding of the air in an advantageous manner in that the air in the downdraft channel must flow opposite to the warm air currents or upcurrents in the room, so that only in the event of negative pressure in the heated rooms the air caught externally of such room flows through the air guide system into the room.
  • the windows and doors closed that is to say, during normal conditions, there continuously prevails in the heated room owing to the outflowing flue gases such a negative pressure which is continuously compensated by means of the air which inflows from the outside through the air guide system.
  • the thus inflowing fresh air is heated as opposed to arriving in the normal manner in a cold state through windows and door cracks in the room.
  • Another and more specific object of the present invention aims at the provision of a new and improved construction of open fireplace which possesses the advantages of the previously mentioned fireplaces with regard to their good utilization of thermal energy both duringfavorable operating conditions as well as also during the aforementioned unfavorable operating conditions.
  • the inventive open fireplace of the previously mentioned type is manifested by the features that at the air outlet location of the at least one downdraft channel there is provided at least one updraft channel with an air outlet opening which opens into the area or room.
  • this ascending or updraft channel is capable of bringing about an acceleration of the air flow in the room.
  • the ascending or updraft channel can be equipped with additional air inlet locations which lead into the room, and which when suitably arranged, for instance in the manner of a Venturi nozzle, bring about a sucking-up of the air in the room into the updraft channel when there prevails in the updraft channel a relatively rapid flow. If such flow cannot prevail from the downdraft or downflow channel, because the warm air currents therein act too strongly, and because no negative pressure prevails in the room (for instance with the windows extensively opened), then at leastin the updraft channel there can be built-up an air current or flow which circulates the air in the room and heats such up.
  • combustion air leading to the firebox already at the catch location or at the ascending portion of the channel system is separated or separately seized from the fresh air which is to be heated, so that only the air in the downdraft channel which serves to heat the room is heated.
  • the fireplace of this development can be rendered useful in that there is provided at the updraft channel at least one lower connection opening in the heated room or area, whereby then colder air flows in at the lower opening to such updraft channel and after being heated again flows out through the upper openings. This can also serve for admixing the room air with the heated-up fresh air.
  • the actual components of the fireplace are formed of pre-fabricated self-supporting shaped bricks which collectively provide a load-carrying construction, and without any additional expedients also can form supports for the smoke channel or flue.
  • FIG. 1 is a front view of a first embodiment of fireplace designed according to the teachings of the present invention
  • FIG. 2 is a side view of the fireplace depicted in FIG. I;
  • FIG. 3 is a vertical sectional view of the fireplace depicted in FIG. 2, taken substantially along the line III- --III thereof;
  • FIG. 4 is a vertical sectional view of the fireplace depicted in FIG. 1, taken substantially along the line IV-IV thereof;
  • FIG. 5 is a perspective view of the different structural components, partially in section, partly shown exploded, partly shown assembled, of the fireplace depicted in FIG. 1;
  • FIG. 6 is a side view, similar to the showing of FIG. 2, of a second embodiment of fireplace.
  • FIG. 7 is a sectional view of the fireplace depicted in FIG 6, taken substantially along the line VIIVII thereof.
  • FIGS. l5 the exemplary embodiment of open fireplace for living quarters or areas, typically a room, as depicted in FIGS. l5 will be understood to comprise a base or mounting plate 1, a floor plate 2, two side portions 3 and 4, a closure plate 5, and a smoke collecting element or flue 6 arranged thereabove. These six elements or components at the same time form a supporting frame for the non-illustrated smoke withdrawal channel.
  • This fireplace furthermore possesses two fire bridges or blocks 8 and 9, a partition wall 7 composed of two plates, a firebox rear wall 10 formed of heat conducting or transmitting material. a cover 11 for the ash chute and three regulating flaps or flap valves 12, 13 andl4.
  • the downdraft or downfiow channel 7 which is connected with the fresh air catch means 17 by means of the ascending channel 17 located behind the partition wall 7 and by means of the connection channels 70, is connected with the updraft or riser channels 3, 4' accommodated in the side walls 3 and 4.
  • the channels 3' and 4' open via the upper lateral openings 3 and 4" respectively with the heated room or area.
  • the flow through the downdraft or downflow channel 7' occurs from the top towards the bottom, i.e. from the higher situated air infeed location 7a to the air outfeed location 712.
  • the natural flow of the warm air current or upcurrent opposes this movement of the air in the channel 7, whereas a negative pressure in the room (owing to the operation of the fireplace) conveys this flow.
  • this flow can be dosed or regulated by the flap 14. Now if an insufficient negative pressure exists in the room or area this flow would die out if there were not present a flow through the updraft channels 3', 4' owing to the warm air currents.
  • the channel 3 has an inclined opening 30 which opens from below into the room, whereas a corresponding opening 40 is provided at the channel 4'.
  • openings can be closed by the flaps or flap valves 31 and 41 respectively, which also can be advantageously used for closing off the fresh air-hot air infeed.
  • flaps or flap valves 31 and 41 can be advantageously used for closing off the fresh air-hot air infeed.
  • the flaps can shut-off the entire infeed of fresh air at the start of the heating operation, so that there prevail ascending or updraft currents in the channels 3. 4' which are brought about by the warm air currents. which then if desired, also can be used for bringing about a stagnating fresh air infeed, if the flaps 31, 4] are appropriately regulated.
  • the flaps 31, 4 can be used for bringing about a stagnating fresh air infeed, if the flaps 31, 4] are appropriately regulated.
  • An open fireplace for living areas or rooms or the like comprising a firebox, side walls, rear wall and flue including an air guide system accommodated in the walls thereof for collecting and heating fresh air, the air guide system including a fresh air catch arranged externally of the room, a downdraft channel which communicates with the air catch and which is subjected to the thermal action of the firebox, the downdraft channel having an air infeed which is situated higher than its air outfeed, an ascending channel for connecting the fresh air catch with the air infeed of the downdraft channel and an updraft channel which is subjected to the thermal action of the firebox, saicl updraft channel having an air inlet communicating with the downdraft channel air outfeed and an air outlet communicating with the room.
  • An open fireplace for living areas or rooms or the like comprising a firebox, side walls, rear wall and flue including an air guide system accommodated in the walls thereof for collecting and heating fresh air, the air guide system including a fresh air catch arranged externally of the room, a downdraft channel which communicates with the air catch and which is subjected to the thermal action of the firebox, the downdraft channel having an air infeed which is situated higher than its air outfeed, an ascending channel for connecting the fresh air catch with the air infeed of the downdraft channel, and an updraft channel having an air inlet which communicates with the downdraft channel air outfeed, said updraft channel being further provided with an air inlet and an air outlet each of which communicates with the room.
  • control means comprises at least one flap member.
