Definitions

  • the invention relates to a fume extraction device comprising an exhaust duct in which a non-return valve is pivotally mounted, which pivots in the exhaust direction due to acting pressure difference from the ambient pressure of a closed position to an open position, and due to a non-return valve in the firing position against a stop.
  • Vapor extraction devices of this type are used for room ventilation, the exhaust duct preferably to an exhaust fan z. B. is connected to the fan of a fume hood to promote the spent air from the interior of the room to the outside.
  • a wall box is known, which is part of this extractor device and forms part of the exhaust duct.
  • the exhaust duct of the wall box separate channels for supply and exhaust air are provided by a partition wall.
  • one of the channels is kept closed by means of a non-return valve, which automatically closes by restoring force in the exhaust duct.
  • a wall box is from the DE 31 03 458 known, in the wall box also separated by a wall a supply air and an exhaust air duct is possible.
  • the non-return valve is mounted in the separation region, so that on the one hand an exhaust air opening results with increasing pressure in the exhaust duct, and on the other hand, a supply air is made possible by the protruding into the second leg.
  • the invention thus raises the problem of an extractor device comprising an exhaust duct, in which a non-return valve is pivotally mounted, to improve to that effect, which is secured against external influences when not commissioning.
  • the achievable with the invention advantages are that the non-return valve falls due to their restoring force from the open position to a secure closed position. This ensures that the closed non-return valve is protected against unwanted flutter in external events, such as wind.
  • the non-return valve cooperates with a locking device such that it is unlocked due to a pressure increase in the exhaust duct to an ambient pressure, so that the non-return valve is free.
  • the locking device is automatically locked again by the falling back flap, so that in the closed position, an automatic opening of the non-return valve is prevented.
  • the locking device is preferably arranged diametrically opposite the pivot axis of the non-return valve.
  • the locking device is in particular by means of a pressure plate, which has flow preventing in the cross section of the exhaust duct and is pivotally mounted against the action of a spring, controllable.
  • the pressure plate is formed, for example, from a leg of an angle lever, wherein the other leg of the angle lever cooperates via a toggle joint with a pivotally mounted locking lever whose nose projects from the outside through an opening provided in the exhaust duct opening in the exhaust duct. In the closed position of the non-return valve, the nose engages in a recess of the non-return valve.
  • a pivotally mounted locking lever is provided, which is locked in the Condition depresses the free end of the pressure plate against the action of a spring.
  • the spring is arranged, for example, between the pressure plate and the closure lever.
  • a number of pins for holding the spring designed as a spiral spring are arranged on the facing sides of the pressure plate and the locking lever.
  • an angle element is advantageously secured to the check valve with an opening formed as a breakthrough depression, which actuates the locking lever to release the pressure plate during the transfer of the check valve in the closed position, so that the nose of the locking lever in the breakthrough Locking the check valve attacks.
  • the locking device for trouble-free operation in a housing on the outer casing venting itself is arranged.
  • FIG. 1 shows in the sectional perspective of a fume extractor 1 partially, the figure shows a portion of the exhaust duct 2, which is also referred to as a wall box.
  • This part of the exhaust duct 2 is used in the wall area, and thus provides the extractor device 1 a passage through an existing masonry.
  • a check valve 3 is pivotally mounted, wherein in the perspective view of FIG. 1 the check valve 3 is shown in the closed situation.
  • This non-return valve 3 opens in the exhaust direction, according to arrow, as a result of acting pressure difference with respect to the ambient pressure p2 from a closed position, as shown, in an open position, shown in the FIG. 2 when the pressure p1 in the Exhaust duct 2 is greater than the ambient pressure p2.
  • the non-return valve 3 falls with decreasing pressure p1 in the closed position against a stop 4 back.
  • a locking device 5 as in the detail views of Figures 3 and 4 is shown in more detail.
  • the locking device 5 now unlocks as a result of the pressure increase p1 in the exhaust duct 2, for example, if the non-illustrated extractor hood is turned on and increases in the exhaust duct 2, the pressure p1 relative to the ambient pressure p2.
  • the locking device 5 unlocks automatically and releases the non-return valve 3. If, for example, the extractor hood is switched off and the pressure p1 drops again, the locking device 5 locks the non-return flap 3 in the closed position against an automatic opening as a result of a pressure drop in the exhaust air duct 2, as described in US Pat FIG. 1 can be seen.
  • FIG. 1 In the FIG.
  • the locking device 5 is arranged diametrically opposite the pivot axis 6 of the non-return valve 3. From the FIG. 4 It is clear that the locking device 5 by means of a flow-preventing in the cross section of the exhaust duct 2 facing, against the action of a spring 7 pivotally mounted pressure plate 8 can be controlled. As can be seen from the perspective view, in this case in the locked position of the non-return valve 3, the pressure plate 8 is arranged under a bevel in the cross-section of the exhaust air channel 2.
  • the pressure plate 8 as such in this case forms a leg of an angle lever 9, wherein the other leg 10 cooperates via a toggle joint 11 with a pivotally mounted locking lever 12.
  • the leg which forms the pressure plate 8 projects into the exhaust duct 2
  • the connected leg 10 projects downwards and forms the toggle joint 11 with a pendulum support 13, which is pivoted upon actuation of the pressure plate 8, so that the locking lever also pivotally mounted 12 is pivoted with its rear end upwards.
  • a nose 14 at the other end of the locking lever 12 projects from the outside through a provided in the exhaust duct 2 opening 15 and engages in the closed position of the check valve 3 in a recess 16 of the check valve.
  • the locking device 5 is arranged in a on the outer shell 22 self-venting housing 23, wherein the housing 23 has a vent opening 24 to the environment.
  • the locking mimic according to the invention can also be arranged in another section of the exhaust air duct of the extractor device.
  • the exhaust duct according to type, material, shape and arrangement within wide suitable limits selectable.
  • the exhaust duct and the space for the arrangement of the locking device, such as the housing 23 are separated from each other substantially airtight. Accordingly, in the present embodiment, only the pressure plate 8 with its side facing the exhaust duct 2, the nose 14 of the Locking lever 12 and the locking lever 17 with the atmosphere in the exhaust duct 2 in contact.
  • the remaining facial expressions are arranged in the housing 23 and are substantially air-tight with respect to the exhaust air duct 2 by means known to those skilled in the art.
  • An example of a possible seal would be the arrangement of sealing lips on the moving components, so that the required for the movement gap between the wall of the exhaust duct 2 and the pressure plate 8, the nose 14 and the locking lever 17 are formed substantially airtight.
  • Another possibility would be the use of a membrane which hermetically encapsulates the moving parts in relation to the atmosphere in the exhaust duct and on the other hand enables the necessary movements.
  • the locking device outside the exhaust air duct in such a way that the surface of the pressure plate that is in contact with the exhaust air atmosphere is substantially flush with the remaining surface of the inner wall of the exhaust air duct. In this way, the flow resistance in the exhaust duct is significantly reduced.
  • the exhaust duct has no undercuts and edges, where dirt could accumulate.
  • the remaining parts of the locking device which likewise project at least partially into the exhaust air duct in the exemplary embodiment explained in detail, would also advantageously be arranged completely outside the exhaust air duct, so that the flow resistance and dirt corners in the exhaust air duct are further reduced.
  • the non-return flap with a projection arranged thereon for example similar to the angle element 21, to project into the closed position through a longitudinal opening in the exhaust air duct in order to reach the locking device arranged outside the exhaust air duct.
  • the longitudinal opening would have to be sealed in a manner analogous to the embodiments described in detail in the skilled person and suitable manner, so that on the one hand the transfer of the non-return valve in the closed position and the open position is made possible and on the other the exhaust duct in the region of the longitudinal opening in each position the check valve is sealed substantially airtight to the atmosphere.
