Definitions

  • the invention relates to a wall box with a ventilation opening on a guide tube and arranged at the end of the guide tube, between a closed position and an open position movable closure lid.
  • Wall boxes are used to ventilate rooms, such as kitchens, by means of a fan and an outwardly leading guide tube, which is closed with a closure lid. It is from the Scriptures DE 20 2005 010 912.6 It is known to electrically open and close the closure lid when the fan is switched on and off. Often, however, no direct electrical connection between the wall box and the blower can be made.
  • closure lid driven by the pressure difference between the air pressure in the guide tube and the outer ambient air, automatically opens against a spring force and closes.
  • the wall box according to the invention discloses an easily assembled and inexpensive venting product.
  • the wall box opens automatically to the desired width.
  • the guide tube may have a round, oval or almost rectangular cross-section.
  • the cover of the wall box closes tightly and prevents the air in and out. A control and / or wiring of the wall box is not necessary.
  • the closure cap is guided axially on guide arms in the guide tube.
  • the pressure loss through the wall box is minimized if on the inside of the closure cap, a flow body is mounted, which directs the air flow formed by the pressure difference at the edge of the closure cap to the outside. It has been shown that a hyperbolic flow body is particularly suitable and the extension force is high by the air flow.
  • the air flow is directed by a flow body and an additional guide body so that it emerges at the edge of the closure lid without turbulence. This means a low pressure loss and also a contamination of the wall at e.g. With exhaust particles loaded exhaust air is largely avoided.
  • the guide body is firmly connected to the flow body via the guide arms so that it moves together with this.
  • the guide body is preferably formed as a funnel-shaped ring, which in combination with the flow body (6) causes an optimal, low-pressure flow deflection.
  • the curvature of the ring is designed so that it initially runs horizontally inside and then deflects the flow by about 70 ° to the outside.
  • the described arrangement of the flow body with the guide body is available both in round and in commercial rectangular ventilation pipes (so-called. Flat channels), for each a corresponding guide tube and a closure lid are provided with a corresponding flow body and guide body.
  • the flow body and the guide body are rotationally symmetrical; in the case of a substantially angular guide tube, the flow body and the guide body have correspondingly hyperbolic surfaces.
  • the flow body is preferably formed from a plastic jacket, which is filled with an insulating material and closed with the closure lid. This construction provides a good insulation against the weather from the outside.
  • the restoring force for closing the closure cap is effected by the self-weight of the closure lid and its guidance on inclined guideways. In another embodiment, the restoring force is effected by a spring, which pulls the lid in its closed position.
  • the other side of the spring like the hinged pivot lever, is secured to the inner wall of the guide tube.
  • the pivot lever is guided via a rod at the center of the closure cap. This prevents tilting of the closure cap.
  • the restoring force is applied by a prestressed tension spring, which acts on the flow body via a reversing lever.
  • the reversing lever is connected via a connecting rod or a thread with the center of the closure lid.
  • the restoring force is applied by a weight attached to one end of a V-shaped pivot lever and the other end engaging the center of the closure cap.
  • the pivot lever is articulated in the guide tube. Due to the gravity of the weight and the adjustable length of the lever arms different force profiles can be adjusted. In this case, it is favorable to apply a high restoring force in the closed state of the wall box, and a lower in the extended state. This closes the wall box at rest safely and in operation, only a slight pressure loss is effected.
  • the restoring force is applied by a torsion spring, which also acts via a lever at the center of the flow body.
  • the torsion spring has a substantially linear force curve.
  • the closure lid is guided over at least two guide arms in the guide tube.
  • the guide arms can also be designed as a linear extension or as a linear guide. To save weight, recesses may be present in the guide arms.
  • a particularly smooth guiding is achieved with rolling bearings on the guide arms, which run on the inner wall of the guide tube. This roundness and other errors of the ideal shape are compensated when the bearings are spring-mounted. Furthermore, it is advantageous if an inclination of the guide tube is compensated by adjusting the spring tension or adjustment of the spring hardness.
  • the flow body can also serve as additional external insulation of the guide tube. Furthermore, it is advantageous if a further insulation between closure cap and guide tube is provided, which prevents an exchange of air in the closed position.
  • the flow body is preferably formed from a plastic jacket, which is filled with an insulating material and closed with the closure lid. This construction provides a good insulation against the weather from the outside.
  • the distance between the air outlet opening and the closure lid depends on the pressure difference or the air volume flow. This can thus be easily determined by measuring the distance. These can be attached to the guide arms markings, which are then optically detected.
  • the wall box has at the outer end of the guide tube on a peripheral flange (30), with which it is fastened in the wall.
  • a sealing ring is embedded, which ensures the tightness of the closure lid in the closed position.
  • the tightness is further enhanced by magnets embedded in the flange and the closure lid. These magnets also ensure the exact vertical orientation of the closure lid in the closed position. This avoids unwanted twisting of the motif when decorative panels with asymmetric motifs, for example a house number, are used.
  • the extension is further improved, since before opening, first a pressure is built up, through which the wall box continues to extend even at low flow rates, as is the case without magnets.
  • Fins are conveniently attached to the flange of the guide tube, which extend into the wall opening and serve there during assembly for a secure fit of the wall box. Through the fins the guide tube is centered and secured against twisting.
  • Different decorative panels can be attached to the closure lid. A simple replacement is possible by a central screw that extends into the cap.
  • the decorative plate can also be designed as a lamp.
  • the higher weight of a lamp compared to a normal decorative plate is compensated by an increase in the restoring force.
  • a small wind generator is housed in the guide tube.
  • the power thus generated can be used to control visual effects, for example by the illumination of LEDs indicating an operating condition.
  • a wall box 1 is shown with its guide tube 2 in the wall 4.
  • the ventilation pipe 3 is attached from the inside.
  • the closure lid 5 is held against the closing force by the air flow 12 in the open position, as in Fig. 1. If the air flow 12 is missing, as in FIG. 2, the closing force closes the closure lid at the wall opening.
  • the closure lid 5 is guided with guide arms 7, one of which is shown in dashed lines.
  • the guide arm 7 slides with the bearings 13 in the guide tube. 2
  • the flow body 6 On the closure lid 5, the flow body 6 is mounted inside, which directs the air flow at the outer edge of the closure lid 5 over into the open. He has a hyperbolic shaped surface 16, which is particularly streamlined.
  • the air flow 12 is further conducted by the guide body 15 so that a low-turbulence flow forms, which exerts a maximum force on the flow body 6. This arrangement causes a minimum pressure loss for the air flow 12th
  • the closing force is applied via a tension spring 22, which is attached to a pivot lever 8, which in turn is mounted in the pivot bearing 19.
  • the strength of the spring 22 and their attachment to the pivot lever 8 results in a force-displacement characteristic for the closing force, which is characterized in the closed position by a nearly constant course of the closing force.
  • the closing force is transmitted via the rod 9 or a thread on the flow body 6 and thus on the closure lid 5.
  • individual magnets 31 are provided on the closure lid 5 and on the flange 30, which further increase the closing force in the closed position.
  • the magnets 31 also serve to center the closure lid 5, so that the angular position between the lid and wall does not change even after multiple opening and closing.
  • Fig. 3 an alternative mechanism for generating the restoring force in a wall box of FIG. 1 and FIG. 2 is shown.
  • the restoring force is generated by a mounted on a lever 8 weight 18.
  • the position of the weight on the lever 8, which in turn is mounted in the pivot bearing 19 is adjustable.
  • the size of the weight 18 and the length of the lever arms of the pivot lever 8 results in a force-displacement characteristic for the closing force, which is characterized by a nearly constant course of the closing force.
  • FIG. 4 shows a similar wall box as in FIG. 1 in the open position.
  • the closing force is applied by the torsion spring 20, which has a substantially linearly increasing spring characteristic. It engages on the spring body 21 on the flow body 6.
  • the air flow 12 also drives a wind generator 40 whose energy can be used for visual displays, for bulbs (LEDs) or for charging a battery.
  • a wind generator 40 whose energy can be used for visual displays, for bulbs (LEDs) or for charging a battery.
  • fins 32 are further attached, which provide for the mounting of the wall box in a wall for a secure fit, as long as a mounting foam is not cured.
  • a further decorative element 50 is attached, which can have a variety of designs and designs.
  • This decorative element 50 is connected to the closure lid 5 and the flow body 6 via a central screw 51.
  • the decorative element 50 can be designed, for example, as a lamp.
  • Fig. 5 the wall box in a vertical mounting position, which may be particularly advantageous for attics apartments, shown in a roof 33.
  • rain cover 53 is attached.
  • the restoring force is generated here by the weight of all moving parts. Since this dead weight is too large to open the wall box automatically enough by the air flow, a tension spring 22 is provided which acts on the pivot bearing 19 mounted in the pivot lever 17 so that the spring force of the tension spring 22 counteracts the weight. In this way, the air flow can open the wall box even in this installation position.
