Definitions

  • the invention relates to an insulating element, a Dämmritt, a furnace assembly and the use of an insulating element or a Dämmappel.
  • Kilns are typically ovens which have a combustion chamber for firing a fuel such as wood or gas. Such furnaces are often used in living rooms and even if this would not actually be necessary due to the presence of central heating.
  • Kilns are said to create a pleasant atmosphere and a positive effect on the indoor climate.
  • generate they have an optical effect, especially when the combustion chamber is visible through a transparent wall from the outside and the fire can thus be seen by a person in front of it.
  • kilns are usually mounted at a certain distance from a house wall. Although this prevents excessive heat transfer, it also takes up a considerable amount of space.
  • insulation elements between the kiln and the house wall can be arranged. The problem here is, however, that typically no appreciable air circulation takes place in sidewalls of the kiln in this case. This can lead to overheating.
  • insulation elements are arranged side by side and / or one above the other or stacked, it is possible in particular to speak of a damping unit. This can be composed of several Dämmimplantationn and adapt to the desired size or contour.
  • the invention relates to an insulating element for attachment between a furnace and a house wall, wherein the insulating element has a contact surface, preferably a bearing plane.
  • the insulating member further includes an air circulation zone adjacent to the abutment surface and having a number of protrusions and a number of air passages therebetween.
  • the projections each extend to the contact surface.
  • the air ducts are each open to the contact surface.
  • the insulating element is formed of mineral material.
  • the air circulation zone is used in particular for the ventilation of a wall, which helps to avoid negative effects such as overheating, heat accumulation or mold growth.
  • the insulating element may be designed to lie partially with the contact surface on the furnace or on the wall of the house. It can also be designed to lie flat or partially against the house wall or to the oven with a further contact surface.
  • a partial system typically allows air circulation, whereas a planar system does not allow air circulation.
  • the additional contact surface is aligned in particular parallel to the contact surface.
  • the contact surface and / or the further contact surface are designed according to an embodiment as contact planes, ie straight or not bent. This is particularly advantageous when a respective side surface of the furnace or the house wall is also straight.
  • the abutment surface and / or the further abutment surface can also be bent, for example, circular-arc segment-shaped or elliptical segment-shaped, in order to adapt to corresponding shapes of the side wall of the furnace or the house wall.
  • the insulating element may have a further air circulation zone which adjoins the further contact surface and which has a number of projections and a number of air ducts arranged therebetween, wherein the projections each extend to the further contact surface and wherein the air ducts each open to the other contact surface are.
  • a ventilation on both sides is possible, for example, such that both a side wall of the furnace and a house wall are ventilated. This can prevent bilateral effects such as heat accumulation or mold growth.
  • the insulating element preferably has a base body.
  • the main body carries the projections. He can also train or wear the other contact surface.
  • the main body can be solid in particular.
  • projections of the air circulation zone and the further air circulation zone also directly adjoin one another or the projections may extend directly to the further contact surface.
  • the projections are formed as nubs, cones, pyramids, truncated cones or truncated pyramids. This allows a shapely design and a simple production. However, other forms are conceivable.
  • the projections may preferably be arranged according to a uniform grid. This leads to a uniform air circulation and also allows easy production.
  • the projections may be formed according to an advantageous embodiment as mutually parallel, elongated teeth, ribs or elevations. This allows a one-dimensional air flow. In addition, such structures can be easily produced. Pips, ribs or elevations may be straight or alternatively also bent.
  • Pines may in particular have a respective triangular cross-section. This allows easy manufacture and reduces the area with which such a point rests against a wall and where consequently no air can circulate.
  • the air ducts may be formed according to an advantageous embodiment as mutually parallel, elongated notches, which preferably have a respective triangular cross-section. This allows an advantageous air flow, in particular when forming the projections as elongated teeth, ribs or projections, in particular a one-dimensional air flow.
  • the air ducts may also be formed as a free space around the projections around according to a likewise advantageous embodiment. This allows in particular a two-dimensional air circulation and is advantageously applicable in connection with an embodiment of the projections as nubs or similar structures.
  • the mineral material is calcium silicate and / or a layered silicate. Such embodiments have proved to be advantageous.
  • the invention further relates to a Dämmussi.
  • This has a number of insulating elements according to the invention, which are arranged such that the respective contact surfaces are identical to each other. This allows a formation of larger structures than specified by a single insulating element.
  • the insulation unit can advantageously adapt to a contour or structure of a furnace or a house wall.
  • the insulation elements can be firmly connected to each other, for example by gluing or screwing. However, they can also be placed loosely on top of each other and / or side by side.
  • insulation elements can be used in the insulation unit on all described versions and variants.
  • the invention further relates to a furnace arrangement.

  • insulation elements and the insulation unit can be used in the furnace assembly on all the described versions and variants.
  • the insulating elements or the insulating unit can also rest against the wall, in particular with the other contact surface. This allows an advantageous filling of the space between the wall and the oven. Alternatively, however, they may also be spaced from the house wall.
  • air circulation zone in particular air from an environment of the furnace assembly passes to a side wall of the furnace.
  • air in particular passes from an environment of the furnace arrangement to the wall of the house. This allows advantageous ventilation of the respective walls, which avoids undesirable effects such as overheating, heat build-up or mold growth.
