Definitions

  • the invention relates to a wall feedthrough unit for connecting a domestic appliance.
  • Building technology devices in particular heat pumps, multifunctional devices according to DIN EN 16573 or central ventilation devices that are installed inside buildings, require a wall duct to the outside through which the required supply air can be supplied and the exhaust air can be removed.
  • a wall duct to the outside through which the required supply air can be supplied and the exhaust air can be removed.
  • at least one end of an air line is provided on the heat pump or the central ventilation device and the other end is attached to a wall duct.
  • a depth-adjustable wall bushing unit is available DE 10 2017 002 396 A1 known.
  • An external part is attached from the outside of the building and an internal part from the inside of the building.
  • the outdoor part also includes an external wall grille and a small animal protection grille.
  • the flow channel is formed within two mutually telescopic pipe sockets, which can be moved relative to one another in order to be able to adapt to the individual wall thickness of a building wall.
  • the wall thickness is known within narrow tolerance ranges, so that it is not necessary to adjust the depth of the flow channel.
  • the use of the known wall bushing unit then has the disadvantage that that due to the unnecessary length adjustment, a not inconsiderable proportion of the cross section of the wall opening is blocked from the air flow.
  • EP 0 651 210 A2 describes a grille for use near an outlet of a heating, ventilation or air conditioning system that includes a frame and a plurality of slats extending between opposing frame members. Each slat has a spindle rotatably mounted in opposing slots formed in opposing portions of the frame. The slots are open at one end to allow insertion of the blade spindle and the spindle is held at the closed ends of the slots.
  • the grid further includes means for holding the lamella spindles in the slots.
  • the retaining means includes a member attachable to the frame of the grille such that a portion of the retaining member engages the slat spindles when mounted on the frame and prevents the spindles from moving out of the open ends of the slots.
  • Building technology devices that suck in or expel air from the outside of a building are, in particular, a heat pump that can be installed inside, multifunctional devices in accordance with DIN EN 16573 or a ventilation device.
  • the three-part design of the wall bushing unit makes assembly particularly easy.
  • the construction of the wall duct unit can be completed gradually as the construction of the associated part of the building progresses.
  • the external wall grille is a finished unit, preferably formed from stainless steel or aluminum sheet.
  • An inner frame extends a little into the depth of the flow channel.
  • the inner frame is surrounded by a frame all around. Several slanted slats are arranged within the inner frame.
  • a wall duct element which is in particular a cuboid body made of EPS plastic foam, is first inserted into a wall recess.
  • the wall recess can be formed from the outset by recesses in the walls, or they can be made into the wall later.
  • the wall duct element is then inserted into the wall cutout and, for example, glued into it so that it is airtight Connection results.
  • the wall duct element is flush with both the inside and outside of the building.
  • the holding frame is put on.
  • a holding frame outer element is provided, which is preferably flush with the end face of the wall duct element.
  • the connection between the holding frame and the wall duct element is made via screws that engage in dowels, which are either screwed into the hardened EPS plastic foam after foaming or which have been foamed directly into the wall duct element.
  • the wall duct element and the holding frame can also be delivered as a fully assembled unit for use in finished building parts, since in this application no adjustment work is necessary on the wall duct element.
  • the outer holding frame element can then be covered with reinforcing fabric and / or plastered, so that a top wall layer is created in which the outer holding frame element is embedded. This means that water running off the building wall can only reach the outside over the plastered surface, but no longer into the space between the outer holding frame element and the front side of the wall duct element.
  • small animal protection grille fastening bottles are preferably provided, into which a small animal protection grille can be hung.
  • a small animal protection grille can also be attached to the external wall grille behind the slats.
  • the connection with the holding frame has the advantage that the flow channel can already be closed off during gradual assembly according to the respective construction progress, without the outer wall grille having to be put in place at an early stage. This advantage arises less when building parts of prefabricated houses, but above all when Subsequent installation of a wall duct element in a building wall.
  • the final step is to put the external wall grille in place.
  • the external wall grille simply needs to be inserted into the area already specified by the holding frame.
  • An inner frame of the external wall grille is pushed between the fastening tabs of the holding frame.
  • a positive connection can be established, through which the outer wall grille is attached to the holding frame and, via this, indirectly to the wall duct element.
  • the fastening points are offset inwards from a wall connection level, i.e. within the flow channel.
  • a wall connection level i.e. within the flow channel.
  • it is provided there to use two screws per fastening tab on the holding frame fastening bottles and to provide elongated holes in the inner frame of the outer wall grille on the rear edge.
  • the screws are tightened, ensuring that the external wall grille is firmly and securely attached. Small tolerances in the plaster layer can be easily compensated for by designing the fastening recesses in the form of elongated holes.
  • the screw connections are preferably arranged in such a way that they are covered by the slats in the outer wall grille and are therefore generally not visible in a front view.
  • the hidden screw connection in the flow channel also has the advantage that there are no miter cuts, rivets, etc. on the frame, which could be visually disturbing and through which water could penetrate.
  • a preferred embodiment also provides that at least one collecting surface in the lower region of the flow channel outer section is formed, which ends at a drip edge.
  • the drip edge in turn protrudes over a lower flow channel surface.
  • the lower flow channel surface is preferably designed to slope obliquely outwards.
  • the fastening means for connecting the outer wall grille to the holding frame are arranged above the collecting surface, as are the rear edges of the slats in the outer wall grille.
  • the small animal protection grille is also arranged above the collecting area in the flow channel. Water that either penetrates through driving rain or is sucked in during the supply air operation of the building services system can drip off at the points mentioned and thus reaches the collecting area and from there outwards via additional slats or draining boards beyond the wall connection level.
  • a preferred embodiment of the wall bushing unit according to the invention provides at least one additional lamella, which is glued or welded to the back of the upper cross bar of the frame, so that the additional lamella extends from a point outside the wall connection plane to the interior of the flow channel.
  • the additional slat thus complements the inner frame in the manner of a lid.
  • the additional slat is advantageous in order to close the flow channel at the top.
  • the additional slat has the dual function of water that may penetrate from above in the wall connection level to the additional slat and is initially drained to the inside.
  • the water can drip onto the top slat in the outer wall grille and then flows out again beyond the wall connection level.
  • This labyrinth concept consisting of an additional slat and an upper slat simultaneously creates a flow-related closure at the top and also creates water permeability.
  • the frame is to be backed with polyethylene foam sealing strips and on the back of the Foam sealing strips to be applied to the wall surface, an additional swelling tape sealing strip should be provided.
  • the ease of assembly of the wall duct unit according to the invention in prefabricated house construction results from the fact that the wall duct element and the holding frame can already be installed in the factory during the production of the building part. All elements necessary for sealing and draining behind water are integrated into the external wall grille.
  • the only assembly step in relation to the wall bushing unit is to place the external wall grille and secure it with the four pre-positioned screws. No further work is necessary on either the external wall grille or the building itself. At the same time, it is impossible for seals to be missed or carried out incorrectly due to carelessness.
  • the flow channel inner section with a round, in particular an ellipsoidal, cross-section continuously merges into the flow channel inner section with the rectangular or polygonal cross-section. This means that large offset areas that would be perpendicular to the direction of flow and create turbulence are avoided at the transition.
  • the wall duct unit In order to separate moisture sucked in during supply air operation as far as possible in the wall duct unit, it can be provided to design parts of the flow channel with at least one small offset step or in a staircase-like manner with several small offset steps. This particularly prevents a film of moisture from forming on the walls and being sucked into the system. With a small offset height of in particular up to 5 mm, maximum up to 10 mm, the main flow is not significantly affected.
  • the central axis of the flow channel rises from the outside of the building to the inside of the building to the extent that all areas of the inner wall in the flow channel have a slope towards the outside.
  • the outer holding frame part can be designed as a frame made of sheet metal without recesses.
  • the small animal protection grille is preferably held interchangeably on the holding frame. This allows it to be removed for cleaning purposes. It can also be exchanged for a grid with a different mesh size, e.g. B. on buildings where high humidity and low temperatures can cause icing on the small animal protection grille in winter.
  • the small animal protection grille is also preferably formed as a stamped part made of sheet metal. A certain amount of stiffening is achieved through embossed ribs and/or vertical or flanged outer edges. If the stamped part is bulbous, the convex side is aligned towards the inside of the building, i.e. pointing away from the outer wall grille, so that these parts do not touch each other.
  • Figure 1 shows a wall bushing unit 100 in a perspective exploded view, seen from the outside of a building. It essentially consists of three assemblies, namely an external wall grille 210, a holding frame 230 and a wall bushing element 110.

  • the frame 216 consists of sheet metal whose outer edge is bent perpendicular to the mirror surface. As a result, a mirror surface limited on both sides for receiving the sealing strips 217, 218 is formed between the outer edge of the frame 216 and the inner frame 220.
  • the swelling tape sealing strip 217 on the top runs across the entire width of the outer wall grille 210. If water running off on the building facade in the corner area of the outer wall grille 210 is not already retained on the swelling tape sealing strip 217, it will be in the miter plane between the sealing strips 218 directed below. It is important that the miter plane is on the upper edge of the side Inner frame parts 221 ends or is even further inward, i.e. above the slats. This ensures that water is guided downwards along the side inner frame parts 221 and drips off there within the flow channel, where the step is formed by the collecting surface 123. However, water cannot run behind the sealing strips 217, 218 and along the side sections of the frame 216.

However, dripping water is forced by the rising outer area 126 to flow towards the center of the collecting surface 123. This means that it cannot collect in the throat areas on the side walls.
  • the swelling tape sealing strip 223 ensures that water that may possibly get between the inner frame part 221 of the outer wall grille 210 and the Holding frame fastening tabs 232 first reach the center of the flow channel, and then from there they have to take the path already described via the collecting surface 123 to the outside.
