Definitions

  • the invention relates to an external wall grille for a wall feedthrough unit for the connection of a domestic appliance, with the features of the preamble of claim 1.
  • 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 duct unit is available from the EN 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 external part also includes an external wall grille and a small animal protection grille.
  • the flow channel is formed within two pipe sockets that can be telescoped against each other and moved against each other 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 an adjustment of the depth of the flow channel is not necessary.
  • the use of the known wall feedthrough unit then has the disadvantage that a not inconsiderable portion of the cross-section of the wall opening is blocked for air flow due to the unnecessary length adjustment.
  • Domestic appliances that take in or expel air from the outside of a building include, in particular, an indoor heat pump, multifunctional devices in accordance with DIN EN 16573 or a ventilation unit.
  • the external wall grille according to the invention provides at least one additional slat that is glued or welded to the back of the upper crossbar of the frame, so that the additional slat extends from a point outside the wall connection plane into the interior of the flow channel.
  • the additional slat thus complements the inner frame like a lid.
  • the additional slat is advantageous in order to close the flow channel at the top.
  • the additional slat has a dual function: any water that may penetrate the wall connection level from above reaches the additional slat and is initially drained inwards via this.
  • the water can drip onto the top slat in the external wall grille and thus reach the outside again via the wall connection level.
  • This labyrinth concept of additional slat and upper slat simultaneously creates a flow-technical closure at the top, but also creates water permeability.
  • the improved sealing concept in the wall bushing unit according to the invention is provided to back the frame with polyethylene foam sealing strips and to provide an additional swelling tape sealing strip on the back of the foam sealing strips, which are to be assigned to the wall surface.
  • the external wall grille is a finished unit, preferably made of 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.
  • the external wall grille is combined with a holding frame that is attached to a wall duct.
  • the holding frame is inserted after the wall bushing has been manufactured. Reinforcement and plaster layers can then be applied to the wall, which enclose the holding frame.
  • the final step is to put the external wall grille in place. To do this, the external wall grille simply needs to be inserted into the area already specified by the holding frame. An inner frame of the The external wall grille is pushed between the fastening tabs of the holding frame.
  • the fastening points are offset inwards from a wall connection level, i.e. within the flow channel.
  • it is intended to use two screws per fastening tab on the holding frame fastening bottles and to provide elongated holes on the inner frame of the external wall grille on the rear edge.
  • the screws are tightened, which means that the external wall grille is firmly and securely attached. Small tolerances in the plaster layer can be compensated for by creating 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 external wall grille and are therefore usually not visible in a front view.
  • the concealed screw connection in the flow channel also has the advantage that there are no miter cuts, rivets, etc. on the frame that could be visually disturbing and through which water could penetrate.
  • 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.
  • a wall duct element which is in particular a cuboid body made of EPS plastic foam, is advantageously 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 an airtight connection is created.
  • the wall duct element advantageously closes flush both on the inside of the building and on the 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 feedthrough element and the support frame can also be delivered as a fully assembled unit for use in finished building sections, since no adjustment work on the wall feedthrough element is necessary in this application.
  • the retaining frame outer element can then advantageously be covered with reinforcing mesh and/or plastered, resulting in a top wall layer in which the retaining frame outer element is embedded. This means that water running off the building wall can only reach the outside via the plaster surface, but no longer into the space between the retaining frame outer element and the front side of the wall feed-through element.
  • the parts of the support frame that extend into the flow channel are preferably provided with small animal protection grille fastening bottles 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 to the support frame has the advantage that the flow channel can be closed off during gradual assembly according to the respective construction progress without the external wall grille having to be attached at an early stage. This advantage arises less when building parts for prefabricated houses, but above all when a wall feed-through element is subsequently installed in a building wall.
  • a preferred embodiment also provides that at least one collecting surface is formed in the lower region of the flow channel outer section, 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 comes in either through driving rain or in a supply air operation of the building services system is sucked in, can drip off at the points mentioned and thus reaches the collecting surface and from there to the outside via further slats or draining boards beyond the wall connection level.
  • the ease of assembly of the wall duct unit according to the invention in prefabricated house construction is advantageously achieved by 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 is designed to transition continuously into the flow channel inner section with the rectangular or polygonal cross-section. This means that large offset surfaces that would be perpendicular to the flow direction and generate turbulence are avoided at the transition.
  • the wall duct unit In order to separate moisture sucked in during supply air operation in the wall duct unit as far as possible, it can be provided to form parts of the flow channel with at least one small offset step. This prevents in particular the formation of a film of moisture adhering to the wall that is sucked into the system.
  • the central axis of the flow channel rises from the outside of the building to the inside of the building, in such a way that so that all parts of the inner wall in the flow channel have a gradient 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 preferably made as a stamped part from sheet metal. A certain degree of stiffening is achieved by embossed ribs and/or vertical or rolled outer edges. If the stamped part is bulbous, the convex side is aligned towards the inside of the building, i.e. away from the outer wall grille, so that these parts do not touch.
  • Figure 1 shows a possible application for an external wall grille 210 designed according to the invention. It is shown here together with a holding frame 230 and a wall duct element 110 in a perspective exploded view, seen from the outside of a building.
  • the cuboid wall bushing element 110 is inserted into a wall cutout in a building.
  • the wall duct element 110 is made in particular from EPS foam to ensure heat conduction is interrupted from the outside of the building to the inside of the building.
  • a flow channel 120 is formed, which is divided into an inner flow channel section 121 with a round cross section and an outer flow channel section 122 with a rectangular cross section.
  • the cross sections 121, 122 continuously merge into one another; Offset surfaces that are perpendicular to the direction of flow are avoided.
  • a shoulder is formed on the underside as a collecting surface 123, which is arranged above a lower flow channel surface 125 that slopes obliquely outwards and which protrudes outwards beyond this.
  • the holding frame 230 consists of a holding frame outer element 231, which is perforated in the manner of a cleaning rail. Fastening tabs 232 extend perpendicularly to this into the flow channel. These partially extend even further into the depth and form small animal protection grid fastening tabs 234. A small animal protection grid 235 is held to them.
  • the outer frame element 232 can be attached to fastening holes 116 on an outer front surface 115 of the wall feedthrough element 110. Dowels are screwed in to reinforce the fastening holes 116.
  • the last step in assembly is to place the outer wall grille 210 on the holding frame 230, whereby fastening recesses (not visible here) on the outer wall grille 210 engage under the fastening screws 233, which are positioned in threads or holes on fastening tabs 232 of the holding frame 230.
  • Grooves 117 are formed in the side surfaces of the flow channel outer section 122 in order to accommodate protruding portions of the fastening screws 233 on the holding frame 230. As a result, the fastening tabs 232 of the holding frame 210 can be positioned close to the side walls of the flow channel outer section.
  • FIG. 2 shows the addition of the external wall grille 210 with the holding frame 230, as in Fig. 1 in a perspective view from the outside of the building.
  • a holding frame outer element 231 rests on the front, outer end face 115 of the wall duct element 110.
  • a small animal protection grille 235 is arranged above the collecting surface 123 in the flow channel.
  • the collecting surface 123 ends at a drip edge 124 above the lower flow channel surface 125, which has rising outer areas 126 on both sides.
  • the external wall grille 210 is shown in a frontal view from the outside of the building.
  • the outer wall grille 210 has a frame 216, which is intended to rest on the outside of the wall and which stands on a drip rail 229. Towards the front, towards the outside, the frame has a front mirror surface 225.
  • the drip strip 229 covers plaster and / or insulation layers below the wall duct element on which the external wall grille 210 is placed.
  • the grid structure of the external wall grid 210 which covers the flow channel in the wall duct element, consists of several slats 211, 213, 214, which slope downwards towards the outside and which overlap each other in the projection onto the wall plane to such an extent that there are no open cross-sectional areas. This prevents driving rain from penetrating the flow channel.
  • an upper slat 211 and several middle slats 213 appear the same. Only a lower slat 214 differs in that it extends outwards beyond the plane of the frame 216 and also has lateral projections 215.
  • FIG 4 the external wall grille 210 is shown in a frontal view of its rear side.
  • An inner frame 220 is provided within the frame 216, which is connected to the frame 216 and is aligned perpendicularly thereto.
  • the inner frame 220 comprises parallel lateral inner frame parts 221, between which the slats 211, 213, 214 are held.
  • the frame 216 has an inner mirror surface that is intended to be placed on the outside of the building wall and is covered with at least one sealing strip 218.
  • sealing strips 218 In the illustrated embodiment of the external wall grille 210, all four mirror surfaces are completely covered with sealing strips 218. These are PE foam sealing strips that are provided with miter cuts in the corner areas. Additional expansion tape sealing strips 217 are placed on the edges of the sealing strips 218.
  • Figure 5 is an enlarged detailed view of the upper left corner area Figure 4 .
  • the side inner frame parts 221 have several punched outs into which z. B. lugs 211.1 of the upper slat 211 are inserted.
  • 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 for this that the miter plane ends on the upper edge of the side inner frame parts 221 or is even further inward, i.e. above the slats. This ensures that water flows to the sides Inner frame parts 221 is guided downwards and drips 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.

  • the step in the flow channel projects into this recess after the outer wall grille has been supplemented with a complete wall feedthrough unit.
  • An important element for achieving safety against water that may run behind the expansion tape sealing strips 217 is an additional slat 212. This is located under the upper section of the frame 216 and, unlike the other slats 211, 213, 214, slopes towards the flow channel, i.e. towards the inside of the building.
  • An additional sealing strip 223 is provided on the outside of the side inner frame parts 221. Its meaning is explained below with reference to Figure 11 explained in more detail.
  • FIG 7 is a detailed view from the upper part of Figure 6 .

It is safely guided away from the rear mirror surface 219 on the frame 216, which is equivalent to a wall connection level W, by means of the additional slat 212. This initially guides the water over the wall connection level W into the interior of the flow channel. There it can then drip onto the upper slat 211. To force dripping, the lower edge of the slat 211 is folded over. The lower edges of the other slats are also designed accordingly.

  • the rising outer area 126 is located laterally outside the area enclosed by the inner frame 220, so that the narrowing of the opening cross section of the flow channel associated with the rising outer area 126 is negligible. Dripping water is but is forced by the rising outer area 126 to flow towards the center of the collecting area 123. It can therefore not collect in the throat areas on the side walls.
  • the 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 is first guided into the middle of the flow channel and then from there has to take the already described path via the collecting surface 123 to the outside.
