Definitions

  • the invention relates to a ventilation device for supplying and/or discharging a volume flow in at least one room, according to the preamble of claim 1.
  • the invention relates to a ventilation device which enables regulated ventilation and soundproofing.
  • the ventilation device arranged between a wall and a fixed frame of a window or a door has a basic housing with at least two openings for air to flow out or for air to flow in, in order to exchange or circulate air between a free, weather-dependent outside and a closed or largely closed interior with air-conditioned, largely constant temperature.
  • Ventilation devices are being moved into a room near the window or door so that the masonry or the wall should not be touched as much.
  • the window profile is used, and in particular the fixed frame into which a ventilation device is installed. This results in openings for the outflow and inflow of air for an interior and an outside.
  • a large number of variants of ventilation devices are known, which guide the air flowing out of the interior and the air flowing into the interior relative to one another in order to enable an exchange of moisture. Alternating routing directions of the air on the same flow path to the outside and/or inside are also possible in a duct in different time cycles.
  • Known ventilation devices or ventilation devices often require additional processing when installed in a window or door or in masonry, since corresponding cutouts are required.
  • the installation of a ventilation device often results in an increase in the frame, which reduces the size of the movable sash, so that the window or door, i.e. the light opening of the window or door, is reduced.
  • a ventilation device is also placed below the fixed frame in a known manner and the masonry is turned up in a very laborious manner.
  • the ventilation device can also be placed under the upper edge of the window opening in the wall to be ordered. Even with this installation variant, a window or door that is smaller in terms of surface area will also have to be placed, which reduces the light area of the window or glazed door.
  • a ventilation device that has already dealt with the known disadvantages is the EP1153250B1 .
  • This ventilation device is also suitable for the simultaneous ventilation of rooms and has a housing that is placed, for example, between the frame of the window or door and the wall, so that a ventilation duct leading to the outside and the inside forms a ventilation flow or an exhaust flow.
  • On the inner side of the opening panel there is a ventilation unit placed on the entire perimeter or on part of the perimeter, which forms the additional profile of the frame and/or the additional profile of the sash and with their arrangement forms the ventilation and soundproofing channel.
  • a disadvantage with this solution is still that the soundproofing affects the area of the window or door in a visually visible way. Furthermore, there are disadvantages of inherent noise due to the course of the air flow in the duct.
  • the channel layout also has a negative effect on the degree of heat recovery.
  • the design of the flow channels shows pressure loss effects of the air flow.
  • a ventilation device after EP 2850272 B1 become known, which is provided for ventilation of at least one room of a building.
  • the ventilation device is installed in the wall (reveal). However, it is not applied to the frame in the direction of the plane of the window, but perpendicular to the plane of the window, which is represented by the frame and the closed sash.
  • the one main extension direction of the frame ventilation device extends perpendicularly to this plane.
  • the frame ventilation device is applied or attached outside the frame and is mechanically attached to it. This results in the aforementioned shift to the side and into the wall of the window to be installed.
  • the well-known ventilation device is structurally designed in such a way that the housing forms a rectangular box which depicts the course of the ventilation ducts.
  • the ventilation device is very large in design and requires a large installation space in the wall, which makes installation complex and impairs the appearance.
  • the wall or wall must be opened accordingly.
  • a ventilation device for supplying and/or discharging a volume flow, which for integration between a wall and a fixed frame of a window or a door having a wall connection joint docks to the fixed frame and extends from an outside to an interior of the window or door.
  • a basic housing which is divided into at least three functional and shape-changed channel sections.
  • a first channel section is designed as a flat channel and lies with a flat side against an end face of the fixed frame, with the outer and inner channel sections on both sides of the first channel section forming a flow opening.
  • the invention is now based on the object of creating a ventilation device of the type mentioned in the introduction, which overcomes the disadvantages of the prior art. At the same time, the ventilation device should achieve a high air output with good sound insulation, low inherent noise and a high degree of heat recovery.
  • the ventilation device depicts an inner and outer channel section, which opens out with a flow opening directed towards the window or the door and a flat channel, each with a radius, towards the flat side of a central channel section are arcuate, with at least one inner channel section starting from the flat side of the flat channel at an obtuse angle greater than 90 ° and thus pointing away from a front side of the window or the door in the direction of the interior.
  • the radius-rounded transition of the duct routing from the flat duct to the inner and outer duct section enables the air medium to pass through the transition of an angled course with little resistance.
  • the flow speed of the air flow is only slightly influenced by this.
  • the radius directs airflow through the ducting in the interior duct portion of the base housing from the window or the Door transitioning into an angled area up to a flow opening that opens out on an inside of the wall. Even the transition of the radius into the angled area turns out to be due a weakened kinked edge of the guide duct for the air flow is advantageous due to the low resistance for the air flow and has proven itself due to the low inherent noise of the air flow.
  • the angle of the inner channel section is formed as an acute angle, so that the flow opening on the inside of the wall shows the greatest distance of the ventilation device from the window or door.
  • the advantageous course of the air flow also has an effect on the sound insulation, which builds up smaller due to the already low inherent noise of the air flow, which results in a small size of the ventilation device and good sound insulation in the long term.
  • the basic housing with its channel sections is arranged in such a way that, in a preferred embodiment, the end of the front face of the fixed frame also includes the flat The end face of the flat channel ends and merges into the radius of the inner channel section, which continues to follow the course arranged in an obtuse arc and finally opens into the flow opening.
  • a direct transition from the central flat duct at the edge of the fixed frame to the inner and outer duct section takes place with a bend pointing towards the window or door or across the visible side of the window or door. As a result, the design therefore requires little installation space in the direction of the interior.
  • the window or door remains unchanged in its original unprocessed state.
  • the fixed frame and the wing that can be moved relative to the fixed frame are thus advantageously retained.
  • the ventilation device does not interfere with the contour of the glazing, so that the light opening made of glass does not have to be reduced either.
  • a special embodiment of the ventilation device provides that all components of the guide duct and sound insulation components are placed in a concealed manner in the wall or wall in a wall connection joint behind the fixed frame. There is therefore no obvious protrusion of components of the ventilation device, which is advantageous in terms of optics. Due to the separate construction and assembly of the window or door and the ventilation device, no further processing is required on the respective components of the window or door or the ventilation device, which can lead to a possible restriction in terms of assembly effort, technical features and appearance could.
  • the ventilation device is preferably laid in the wall or in the reveal.
  • the ventilation device does not extend in the direction of the plane of the window or door adjacent to the fixed frame, but perpendicular to the window plane, which is represented by the fixed frame and the closed sash.
  • the basic housing is formed in a longitudinal, transverse and depth direction, with a fastening section or strip area extending approximately at the level of the central axis of the longitudinal direction over the length of the middle first duct section of the flat duct in the transverse direction, which partially controls the volume flow up to the Inner and outer channel section divides.
  • the fastening section can preferably be used to mechanically fasten the ventilation device to the fixed frame in the applied or attached area of the flat duct.
  • the window or the door can be anchored in the wall or in the brick wall.
  • the fastening section dividing the longitudinal direction also counteracts this by anchoring the window or door as a stably fastened arrangement in the wall or wall an intervention from the outside and also offers resistance to a possible attempted break-in in the area where the ventilation device is arranged.
  • the size of the window or door remains the same even with the installation of the ventilation device, whereby the ventilation device is arranged on one of the vertical fixed frames to the side of the window or door and is sunk into the masonry in the wall connection joint of the reveal.
  • the occupied space for the ventilation device in the wall does not extend along the entire height of the window or door, but occupies only a small part in height and also requires little depth in the depth direction due to the slender shape of the flat duct of the ventilation device the reveal or the wall.
  • the main extent of the ventilation device is in the longitudinal direction of the vertical direction, ie in a direction transverse to the direction of flow and the mounting surface of the fastening section on the flat side, which is assigned to the fixed frame.
  • the transverse dimension results from the thickness of the window or door and the interior and exterior channel sections located on each side of the central channel section.
  • the length of the transverse direction is less than the thickness of the wall or masonry.
  • the fastening section preferably consists of a dimensionally stable material and/or is structured in a dimensionally stable manner, for example formed as a rib profile, with the fastening section not protruding beyond the thickness of the flat duct.
  • the basic housing through which air flows is designed in two parts.
  • a first flow opening leading to the outside associated with a first housing half and the inwardly leading second flow opening, which opens into the interior and is associated with a second housing half, can thus be telescopically displaced in the transverse direction in the central channel section of the flat channel.
  • a setting of varying thicknesses of the window or door is therefore just as possible as an adjustment with different wall thicknesses.
  • the inner duct section arranged toward the interior has an actuating handle in a free operating field for controlling an airflow control device, which is preferably formed from a ventilation flap and/or a slide and regulates the volume flow of the airflow.
  • the ventilation flap is rotatably mounted in a rectangular flat duct on an inner wall of the flat duct, with the ventilation flap being coupled to the actuating handle with actuation, for example of a rotary knob, causing a rotary movement of a leg of the ventilation flap, with a free end of the leg on the opposite inner wall of the flat duct comes to rest and closes the flat duct and thus the air flow cross section.
  • actuation for example of a rotary knob
  • the leg of the ventilation flap is approximately transverse to the flat duct wall and to the air flow.
  • the flow cross-section can not only be opened and closed using the rotary knob, but also the air flow can be reduced and thus regulated with infinitely variable adjustment of the ventilation flap.
  • the basic housing carries a sound insulation foam and/or a sound insulation module lying concealed within the wall connection joint on the inner duct section facing the outer shell of the interior.
  • the insulating layer applied overlays the inner channel section arranged in the interior and encloses the flow opening opening into the interior without encroaching on the inside of the wall or wall facing the window or the door.
  • the ventilation device can be positioned on both sides of the window or door without structural changes by simply turning it. Using the same components of the ventilation device arise with the same arrangement of the components, the same installation situation and the same air flow conditions with the same sound insulation.
  • the duct sections forming the basic housing of the ventilation device are preferably joined in a form-fitting manner or are formed in one piece. All functional components can be quickly and easily assembled and fixed in position.
  • the integrated functional components in the basic housing are arranged completely covered with a covering weather protection in an advantageous manner by a removable weather protection cover on the outside and a cover cap in the interior of the flow opening. Possible contamination, which can contribute to an impairment of the service life of the ventilation device, is ruled out by the sealed connection of the weather protection cover and the cover cap.
  • the functional components of the control device or the duct sections can also be removed for possible maintenance by releasing a positive and/or non-positive connection of the weatherproof cover or the cover cap and, if necessary, cleaned.
  • the weatherproof cover and the cover cap can be designed as a panel, perforated plate, grid element or as a slat or blind element.
  • the ventilation device is designed in particular to divert any type of weather-related moisture input, such as that which can occur in the case of driving rain, snowdrifts or shear water, to the outside.
  • the outer weather protection cover or the outer channel section has a special, outward-leading first flow opening in relation to the transition opening with a sloping course. This means that the weather protection cover or the outer channel section can be cut at an angle in the lower horizontal area of the flow opening. In this way, a gradient can be realized within the basic housing when this is in the installed state. It is preferably provided that the slope runs in the direction of the outer visible weather protection cover, so that moisture that enters the air-flow-through-flow opening from the outside via the flow opening immediately drains freely again via the flow opening.
  • Condensed water which can arise when air is discharged from an interior space to the outside, can also run off in a simple manner in the direction of the first outer air opening. This means that complicated and usually much larger, necessary weather protection measures can be dispensed with.
  • the present invention is not limited to any particular grade of slope. However, the sloping profile should be designed in such a way that when the ventilation device is in the installed state, there is a fall that is safe from thrust water.
