Definitions

  • the present invention relates to a method for aerostatic separation the fireplace of a fireplace from the immediate vicinity by means of a Air curtain according to the preamble of claim 1, and a device to practice the method as described in the preamble of claim 7.
  • the most common solution is to complete the firebox to include, with front, i.e. on the one facing the room Side, a transparent wall made of glass or similar material attached through which one can see the flames, but through which the space completely isolated from the fireplace.
  • a transparent wall made of glass or similar material attached through which one can see the flames, but through which the space completely isolated from the fireplace.
  • An example of such a solution is in the US-4'248'206 shown, to improve the efficiency an air curtain in the part behind the transparent wall is generated, which is fed with outside air by means of a fan, and who brushes this wall and heats up.
  • a fireplace of this kind may have good heat efficiency, but obviously that is missing direct contact between the fire and the ambient air.
  • construction is perceived as a foreign body in space, in the way it is normal cast iron or ceramic stoves.
  • EP-0766046-A2 Another subject of some interest under the present Invention is then shown in EP-0766046-A2, which is a gas heater with flammable liquid.
  • Such chimney types which only for this reason alone, don't let it be compared to real fireplaces, in which wood is burned and to which the present invention relates - still have two basic disadvantages, against which the invention is intended to remedy the situation, namely that on the one hand it is harmful to health Generate emissions, and that on the other hand they are not realistic Make an impression of a fireplace, i.e. that they have no direct view of the Flemish allow.
  • EP-0766046-A2 proposes to overcome these disadvantages the application of forced air circulation by means of a fan is pressed through an opening in the upper part of the opening of the fireplaces is arranged.
  • the purpose of the present invention is to overcome the disadvantages of the above to overcome known partial solutions and is designed to create an atmosphere of well-being thanks to the burning fireplace in the room, the main disadvantages of the fireplace with an open fire overcome, namely the escape of smoke into the surrounding space and the spark spray with the corresponding fire hazard.
  • the inventive method and the device for its exercise allow a satisfactory thermal efficiency of the fireplace to achieve because there are no partitions between the fireplace and the room are present without complex and delicate heat exchanger devices would be used as in the case of the environment by means of a more chimneys or less see-through wall are essential are.
  • the inventive idea is not that of an air curtain as such to create the opening of the fireplace since today the formation of an air curtain the expert in the field of aerostatic separation from one another connected spaces is a well-known technique, but that to create air circulation in a closed circuit, whereby not to understand the concept of a closed circuit in an absolute sense is that the air in this circulating circuit has no contact with the environment, but that the main part of the circulating air stays in the cycle and goes through it several times while only one small proportion of the air mixes with the ambient air, namely where the air curtain is in contact with the environment.
  • Fig. 1, 1 and 2 denote the side walls of a fireplace or fireplaces for a living space that is completed by a hood 3 above is in the middle of a smoke exhaust pipe 4 from the highest point of the Hood goes out.
  • a fireplace usually faces a firing surface 5 for the fuel, often as a grate is designed to facilitate the supply of combustion air to the fire.
  • the living room fireplace is of course provided with a rear rear wall 6, while it is open towards the room to the view of the To release flames, and also to prevent the emission of radiant heat in to allow the surrounding space.
  • the elements described so far form the basic structure of every living room fireplace.
  • FIG. 1 apparatus suitable for the method is shown in FIG. 1 and comprises a fireplace 7 through a fireplace with a paving or a firing surface 5, a ceiling or hood 3, a rear wall 6 and two side walls 1 and 2 is formed.
  • the firebox is forward open.
  • the front opening of the fireplace 7 is at its full height and across its entire width by an air flow indicated by the arrows f coated, which forms an air curtain.
  • An air curtain is understood to be an air flow that is two connected Completely separates spaces in the aerostatic sense and prevents the exchange of air between the two rooms.
  • the present invention therefore provides that in addition to the front opening of the fireplace (these sides can be both the top and the lower one, as well as the two side walls) at least one opening more precisely, there is an air injection opening and an air suction opening.
  • opening in this context is to be understood as a slot of any kind or one Mouth through which an air stream can pass.
  • Such slits that form an opening can advantageously have a cross section, which is suitable for generating a unidirectional air flow in the In the event of a blowing opening, or an air extraction opening, the air from all directions sucked in evenly.
  • the air blowing opening is designated 8, while the air suction opening is indicated with 9.
  • the air blowing opening 8 is in this embodiment arranged in the upper part of the opening of the firebox, while the suction opening 9 is arranged in the lower part such that the air curtain according to a preferred embodiment of the present invention, because this best allows using the separation effect of the air curtain the air supply to the fireplace to combine - extends from top to bottom.
  • a single blow opening 8 is shown, and a single one Suction opening 9, but this does not rule out that a larger one Number of blow holes and suction holes can be attached, each be acted upon individually.
  • the essentially closed air cycle to realize which forms the basic idea of the present invention, it is provided, in the embodiment according to FIGS. 1 and 2, that the Blow opening 8 with the suction opening 9 by means of a closed connecting channel 10 is connected, in which at least one fan 11 acts, which circulates the air in a closed circuit, which from the air curtain f consists of at least one blow opening 8 to at least one suction opening 9 moves, and the connecting channel 10.
  • the connecting channel 10 is designed as a double channel 10 'and 10 ", each Half channel 10 'and 10 "one end of at least one blow opening 8 with connects the corresponding end of at least one suction opening 9, wherein a fan 11 ', 11 "is arranged in each of the half channels 10', 10", which circulates the air (compare arrows f, f 'in channels 10', 10 ").
  • Laminar means, which means that the airflow over a maximum possible Length of the air curtain should be kept laminar.
  • an air speed in the air curtain measured at the discharge opening 8 choose between 0.5 to 5 m / s.
  • the Air speed must depend on the dimensions of the living room fireplace, and in particular the distance between the blowing opening 8 and the suction opening 9 can be chosen favorably. This can be an optimal Exit speed can be found at the blow-out opening 8, the one complete formation of the air curtain with minimal air loss ensures from the closed cycle: this speed will determined by means of calculations and suitable tests; Measures the fall within the competence of the specialist in the field.
  • the air curtain f according to the invention must be so be designed so that the air supply to the air flow of the air curtain f from the Environment is between 10% and 40% of the total circulating air volume.
  • the air curtain f according to the invention must be so be designed so that the air supply to the air flow of the air curtain f from the Environment is between 10% and 40% of the total circulating air volume.
