Definitions

  • the invention relates to a supply air device of the type specified in the preamble of claim 1.
  • a supply air device for ventilation of living spaces is known, which is transverse in the flow channel arranged guide surfaces for the flow medium.
  • an elastic band is provided, which is attached to one of its edges and arranged in such a way that it can be moved by pivoting against the essentially convex bearing surfaces by the supply air flow resulting from the difference between the pressure prevailing inside and outside the living space, and thereby a reduction in the free cross section within the flow duct of the supply air.
  • the known control device Since the room climate in living rooms is determined not only by the properties of the supply air but also by a number of other parameters, the known control device with the above-described structural design of the elastic shut-off element is only of limited suitability for comfortable ventilation of a living room.
  • the ventilation device has the disadvantage, for example, that the fresh air flow cannot be directly influenced externally by means of further control variables. Furthermore, disturbing movement noises are caused by the flaps.
  • the invention has for its object to provide a supply air device of the type mentioned, which has an improved possibility of influencing the air flow rate or a reduced noise pollution when controlling the volume flow.
  • the invention includes the knowledge that the effectiveness of a supply air device can be significantly improved if there is the possibility of impressing an additional manipulated variable which is formed as a function of a further parameter which determines the room climate of the room to be ventilated. Furthermore, by avoiding hinges or stop surfaces, a reduction in noise pollution during the function of the shut-off element is ensured.
  • needs-based home ventilation is possible, which meets the high requirements of today's structural thermal insulation and enables needs-based ventilation of the individual living spaces without causing disturbing impairments, such as noise (rattling or squeaking noises) by the movement mechanics or from the environment as well disturbing drafts in the event of gusts or high wind pressure on the respective side of the building.
  • disturbing impairments such as noise (rattling or squeaking noises) by the movement mechanics or from the environment as well disturbing drafts in the event of gusts or high wind pressure on the respective side of the building.
  • the elastic shut-off element is designed as a narrow band and is connected to a cylindrical body arranged transversely to the flow direction and about its longitudinal axis.
  • This body is designed to allow the supply air to be regulated to flow through, and at the same time has a relatively low flow resistance.
  • the cylinder jacket surface consists of a plurality of webs of different widths, which extend in the direction of the longitudinal axis of the cylinder. One of the webs is designed in such a way that its width allows it to close the entire flow cross-section.
  • the elastic shut-off element is fastened to one of the longitudinal edges of this web and at the same time has a width which enables the shut-off element to close the entire flow cross-section with a corresponding pressure difference when the cylindrical body is in a position in which it completely releases the flow cross-section .
  • the arrangement of the elastic shut-off element described above advantageously ensures that the free flow cross section of the supply air duct is reduced to a required size by simply rotating the cylindrical body can be reduced and the remaining cross-sectional area can be further reduced or completely closed by means of the elastic shut-off element depending on the differential pressure present in the flow channel.
  • a stop attached to one side of the wall is provided within the flow channel and limits the respective free cross-section of the flow channel between itself and the opposite wall. If the cross section of the flow channel is closed by the elastic shut-off element when there is a large pressure difference, then it rests with its free end sealingly against the stop and at the same time is pressed against the wall of the cylindrical body and thereby supported by the narrower webs. Due to the possibility of being supported by these webs, the elastic shut-off element can be produced from a band with a small thickness and therefore has a greater sensitivity to pressure fluctuations.
  • a preferably meandering profile is provided on this section of the band in accordance with a favorable development of the invention. This ensures a simple increase in the rigidity of the material without impairing its elastic properties.
  • the band-shaped elastic shut-off element is fixed on one of its long sides to the wall of the flow channel.
  • a substantially cuboidal body is formed on the correspondingly free end and extends over the entire width of the flow channel.
  • This body preferably consists of a foamable plastic and has an essentially circular segment-shaped cross-sectional profile.
  • a foamable plastic advantageously ensures that the total mass of the elastic shut-off element increases only insignificantly.
  • a sealing lip extending over its entire length is provided on the plastic body. This nestles against a stop that determines the size of the flow cross section and ensures that the flow channel can be closed with sufficient tightness if necessary.
  • the shut-off element is a flap mounted on a flexible band, which can be pivoted about the mounting point in a particularly quiet manner.
  • the cross-sectional area of the segment shaped like a circle is changed in such a way that the radius of the circle segment decreases in the direction of the closing movement of the shut-off element.
  • the course of the curved boundary line of the cross-sectional profile of the molded body is a measure of the change in the effective radius, which determines the free flow cross section between the stop and the lower edge of the molded body, as a function of the pivoting angle of the shut-off element. It has proven to be beneficial for the control behavior of the arrangement if the curved boundary line has the shape of a square parabola.
  • a rotatably mounted shaft is provided as an additional device for changing the free flow cross section, the longitudinal axis of which extends essentially parallel to the longitudinal axis of the flow channel.
  • a lever designed as a molded part, which extends in the radial direction transverse to the longitudinal axis.
  • the lever tapers in the direction of its free end and lies on the body molded onto the elastic shut-off element when it is in the rest position (hanging vertically at zero flow velocity).
  • the lever is convex on the side facing the elastic shut-off element, so that a "soft" action on the molded body is ensured by rotating the shaft via the lever, the elastic shut-off element being pivoted into the closed position.
  • FIG. 1 shows the longitudinal section of a rectangular flow channel 5 in the area in which the means 2 and 3 required to regulate the amount of air 6 to be transported through the flow channel are arranged.
  • the regulation takes place by changing the free flow cross-section, which is located between the upper wall 4 of the channel 5 and a stop 11 provided on the lower channel wall.
  • a cylindrical body 2 is arranged such that it can be rotated about its longitudinal axis in such a way that it projects with a quarter of its lateral surface into the flow cross section to be changed.
  • the lateral surface of the cylindrical body is subdivided into a plurality of webs 2.1, 2.2, 2.3 having a different width, so that this body has a relatively low flow resistance overall in the "OPEN" position of the flow regulator shown.
  • the outer surface is subdivided into a web 2.1, which forms a quarter of the outer surface, into a relatively narrow web 2.2, which is supported on the stop 11, and a plurality of rod-shaped webs 2.3, which are in the area between the wide web 2.1 and the narrower one Web 2.2 are arranged and have the task of supporting the elastic shut-off element 3 when it is pressed against the cylindrical body 2 from a certain size by the action of the differential pressure (pressure difference between the inflow and outflow side of the flow channel 5) and thereby reduces the free flow cross section .
  • the shutoff element 3, which is preferably made of soft rubber, is fastened on one side to the longitudinal edge of the wider web 2.1 facing the flow cross section to be changed and also extends over the entire width of the flow channel 5.
  • the supply air device 1 shown in Figure 1 is shown schematically in positions which arise in the different regulatory situations. If the cylindrical body 2, which can be rotated about its longitudinal axis, is in its basic position, in which the variable flow cross-section has its maximum value, it is closed only by the elastic shut-off element 3 as a result of the air flow 6, which moves within the flow channel 5 due to the pressure difference .
  • the elastic element 3 is supported on the rod-shaped webs 2.3, whereas the narrow and wide webs 2.1 and 2.2 limit the free flow cross section in the transverse direction (FIG. 2).
  • the wide web 2.1 partially engages in the free flow cross section and reduces the amount of air flowing through 6.
  • the elastic shut-off element 3 is slightly deformed (FIG. 3) and can react sufficiently to the changing pressure differences within the flow channel 5. If a predetermined maximum pressure difference is exceeded, the flow channel 5 is completely closed (FIG. 4). Since the dimensions of the elastic shut-off element 3 are chosen such that they correspond to a quarter of the lateral surface of the cylindrical body 2, the free end of the elastic shut-off element 3 nestles against the stop 11 provided on the inner wall 4 of the flow channel 5 and seals in a favorable manner a possible longitudinal gap between the cylindrical body and the wall 4 of the flow channel 5.
  • the shut-off element 3 is provided with a profile 3.1 at this point in accordance with a favorable development of the invention shown in FIGS. 5 and 6.
  • the profiling 3.1 according to FIG. 6 represents of the section along the line A ... A in FIG. 5 has a meandering cross section and its geometrical dimensions are chosen such that sufficient elasticity is still present when suppressing vibrations associated with considerable noise is to achieve the required shut-off effect by the elastic shut-off element 3.
  • FIGS. 7, 8 and 9 schematically show a further advantageous embodiment for a supply air device according to the invention in operationally different positions.
  • the partially elastic shut-off element 3 ' extends transversely to the direction of flow and has a band-shaped design and is fastened to the wall 4 of the flow channel 5 on one of its long sides.
  • the elastic shut-off element 3 ' which at least consists of soft rubber in the hinge area, forms, together with a three-dimensional body 10 formed on its free end, a control flap 3' 'which can be deflected by the air flow around the clamping edge E.
  • the hinge area is therefore completely noiseless.
  • the molded body 10 has a cross-sectional profile essentially in the form of a segment of a circle.
  • the free End of the molded body 10 carries an elastic sealing lip 9 on the upstream side.
  • the molded body 10 advantageously consists of a foamed plastic or a blown molded part, so that the control flap 3 ′′ has only a very small mass and therefore a sufficiently high sensitivity the supply air device 1 is guaranteed with a low-noise operation. As the flap closes more and more (FIG. 9), the body 10 dips more and more into the opening area of the passage opening and increasingly closes it.
  • the residual opening cross-section is determined as a function of the position of the shut-off element in such a way that the volume flow occurring at the respective wind pressure is kept essentially constant by the corresponding position of the shut-off element.
  • a pivotably mounted shaft 2 ′ is provided, which extends parallel to the longitudinal axis of the flow channel 5. It penetrates the elastic shut-off element at its clamping point on the wall 4 of the flow channel 5.
  • the shaft 2 ' has a radially extending lever 7, which is supported at the point on the integrally formed body 10, at which it is connected to the elastic shut-off element 3 'is connected ( Figure 7).
  • the control valve 3 ′′ is influenced by the air flow 6 around the clamping point of the elastic shut-off element 3 'pivoted. This pivoting movement is limited in angle by a stop 8, so that even with a large differential pressure, a small flow cross-section is always available for the air passage.
  • the stop 8 is provided on the central section of the shaft 2 '. It extends transversely to the shaft axis in the direction of the center of the flow channel 5 and is arranged on the shaft circumference rotated by 90 ° relative to the lever 7 (FIG. 8). At the wind speeds normally to be expected, the flap does not hit the opening edge, so that whistling noises are avoided.
  • the sealing lip 9 made of soft rubber at the free end of the body 10 is effective at the stop 11 ′ and closes the flow channel completely.
  • the body 10 molded onto the elastic shut-off element 3 ' has a cross-section in the form of a segment of a circle.
  • the radius R of the circular segment gradually decreases in the direction of the closing movement. This has the advantageous effect that the distance between the stop edge 11 'and the arcuate boundary line 12 of the free end of the body 10 gradually decreases until the control flap 3''is in the closed position (variation of the opening width depending on the angular position of the control flap 3'').
  • FIG. 10 shows another exemplary embodiment of the ventilation device according to the invention in an exploded view.
  • An outer housing 101 is locked in a correspondingly prepared opening in the wall by means of two fastening bands 102 and 103 designed as angle irons and insertable between ribs of the housing.
  • the outer housing is made of plastic and is made as a molded part.
  • the end to the outer wall is formed by a transition piece 104 and a cover 105.
  • the latter forms a rain protection and can be aligned by means of the telescopic extension piece.
  • the latter two parts are also made of plastic.
  • a silencer 106 made of a corresponding foam material is inserted into the housing and has two passages of square cross section.
  • the control insert 107 acts on the shut-off element 108 by means of suitable drive means, which in the drawing is in the rest position (passage open, no wind pressure).
  • the one connected to the shut-off element Shaped body 109 dips through the passage opening 110 when the shut-off element 108 closes, the passage cross section being reduced beforehand in each case to such an extent that the volume flow rate occurring at the wind pressure holding the flap in the respective position is essentially constant.
  • annular diaphragm 111 In the direction of the interior, there is an annular diaphragm 111, which receives a dust filter 112, before the control insert.
  • the air outlet is in turn covered by a screen 113.
  • a bolt 115 By means of rotation of an operating lever 114 which is concealed behind the screen 113, a bolt 115 can be pushed by means of an axis of rotation 116 behind the shut-off element 108 inclined in its open position, which is thus positively guided into a vertical position in which the shut-off element is locked in its closed position.
  • the volume flow limitation works up to a wind pressure of 300 N / m2, corresponding to a wind force component of 10 directed perpendicular to the wall.
  • the embodiment of the invention is not limited to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown, even in the case of fundamentally different types.
  • the control part of the supply air device shown can interact with electronic circuits such as those shown in other patent applications by the applicant and have the object of influencing the current cross section of the supply air opening as a function of various influencing variables.
