Definitions

  • the invention relates to a valve heater element for the controlled release and heating of a flow of air in a building.
  • Valve heating elements of the type mentioned above are used for the controlled delivery, directing, throttling and, if necessary, reheating of an air flow.
  • geothermal preheated air is supplied through a wall or ceiling outlet on which the valve heating element is arranged, with a centrally controlled volume flow.
  • a heat pump is often used to cover the base load for heating. These base load generators thus supply the rooms with preheated air. In order to maintain the desired room temperature when the outside temperature drops, the room supply air needs to be reheated.
  • the required flow of air into the room is achieved through a suitable design of the outlet, in particular through the use of a suitable valve shape.
  • a suitable valve shape When installed in the building ceiling, for example, the air is guided into the room at a suitable angle (conical) using a plate shape.
  • a suitable angle conical
  • a plate shape When installed in the inner wall of a building, on the other hand, importance is often attached to a large range of air, so that such valves often have a long-throw characteristic.
  • connection lines for mains voltage must therefore be designed to be temperature-resistant, for example in the area of the air flow, using suitable insulating materials such as silicone or Teflon.
  • a ventilation device for simultaneous ventilation of rooms according to the prior art is disclosed in documents DE 38 28 011 A1 and EP3109560 described.
  • valve heaters according to claim 1 This object is provided by valve heaters according to claim 1. Advantageous configurations are contained in the dependent claims.
  • the invention relates to valve heaters for controlled delivery and heating of a flow of air, the valve heater including a terminal housing and a heater housing.
  • connection housing is used for on-site fastening of the valve heating element in a building wall or building ceiling and for feeding in an air line connection and an electrical mains cable. Typically, it is firmly mounted in a prepared opening in a wall or ceiling and connected to a duct for supplying preheated air.
  • channel is not limited to any specific design, but includes all forms of channels, tubes, hoses and the like.
  • attachment in a ceiling should always be included.
  • the heating element housing serves to accommodate (at least) one electrical heating element, with which heat can be generated by supplying electricity and can be given off to the air flow flowing through the valve heating element.
  • junction box and thermal element box are each separate boxes with optional sub-components.
  • valve heating element of the type defined above is also referred to below as a "basic valve heating element" and is further developed by the aspects of the present invention explained in more detail below.
  • the features of the valve heating elements according to the various aspects of the invention can optionally be combined with one another as desired.
  • the basic valve heater according to the invention has a terminal housing with an air flow separated Manhole on, in which a terminal strip is arranged for connection to the power cord.
  • the conveyed air flow is structurally separated from the area in which the electrical mains cable runs through the cable duct.
  • the mains cable is no longer routed through the air flow and is therefore no longer exposed to the high temperatures that may potentially prevail there or to unwanted mechanical wear or damage from cleaning equipment in the course of line inspections and in particular cleaning work.
  • a special insulation of the mains cable e.g. with Teflon
  • the conventional insulation e.g. made of PVC
  • the mains cable can be connected to the connection strip in the cable duct, from which the electrical supply of the valve heating element is carried out.
  • the terminal strip can be formed in one piece with the terminal housing. However, it is preferably a separate component that is independent of the connection housing, since it can then be connected to the mains cable outside of the connection housing and can therefore be carried out more easily.
  • latching means are provided in the connection housing or specifically in the line duct for quick latching of the connection strip on the connection housing.
  • screw means can also be provided for fastening the terminal strip, for example in the form of a threaded screw hole.
  • a base valve thermal element includes a terminal block disposed within the junction box for connection to the power cord and a header disposed within the thermal element body, the pin header electrically contacting the terminal block upon mating of the junction box and thermal element body.
  • Terminal strips and pin strips are typically designed like the plug and socket of a plug-in device, so that when they are plugged together, they create electrical contact between one, two, three or more lines in the terminal strip or pin strip (e.g. for forwarding external conductors, neutral conductors and/or protective conductors of a mains voltage) .
  • this electrical contact is produced simultaneously with the joining of the connection housing and the heating element housing, so that no further assembly steps are necessary for this.
  • this intrinsically interrupts the mains voltage when the heating element is removed from the connection housing for the purpose of inspection or maintenance, so that the corresponding safety requirements are met and there is no danger to people.
  • the invention relates to a basic valve heating element, in which the connection housing has at least one tension claw on its outer circumference, which can be swiveled radially outwards and adjusted axially.
  • connection housing can be fixed simply and securely to a wall plate, in the opening of which the connection housing is arranged, by means of the claw fastener.
  • the pull claw can engage behind the wall plate by pivoting it radially outwards and then clamp it by a corresponding axial adjustment towards the wall plate towards the connection housing on the wall plate (or the back of the plate on the wall or ceiling side in the sense of a rear wall attachment).
  • the opening in the wall plate is matched as precisely as possible to the diameter of the connection housing (with the pull claw not swiveled outwards).
  • Two, three or more claws of the type described are preferably provided, which are typically arranged equidistantly distributed over the circumference of the connection housing.
  • the invention relates to a basic valve heating element, in which the heating element housing has a circular passage for the air flow, in which a non-square, preferably cross-shaped, heating coil is arranged.
  • the heating register is used to heat up an air flow, the heating register itself typically being flown through by the air flow in order to produce as large a surface contact as possible.
  • the invention relates to a basic valve heating element in which a heating register is arranged in the heating element housing and has separate connections to at least two different heating segments thereof.
  • this is a valve heating element, which also according to the previous
  • the heating register can therefore be used in at least two ways, which differ in the different activation of heating segments (or heating zones).
  • the connections can be selected in such a way that optionally all heating segments contained in the heating register are traversed by current, or that some heating segments (for example those lying at the edge) are not traversed by current.
  • the heat output of the heating register can be adapted to the needs of the respective air outlet in a building.
  • the invention relates to a basic valve heating element in which a heating register is arranged behind a protective grid in the heating element housing.
  • the protective grid is usually made of an electrically non-conductive material and typically has holes that are so small that a human finger cannot come into contact with the electrically conductive surface.
  • the mesh size of the touch protection grid must be designed in accordance with the applicable rules of technology (VDE test finger compliant) depending on its overall height and thus the distance to the register surface
  • the protective grille mentioned above is advantageously an integral part of the thermal element housing. Alternatively, it can also be inserted into the heating element housing via a snap-in connection. In this case, for safety reasons, the locking connection is preferably designed in such a way that disassembly is only possible using the tool required for this purpose, so that the protective grille cannot be removed without authorization.
  • the heating register is advantageously inserted and securely held in the heating element housing via a snap-in connection.
  • the invention relates to a basic valve heating element in which a valve disk is arranged on the heating element housing in front of the air outlet and is connected to the heating element housing at variable distances.
  • a valve disk is used to shape the inflow of air into the room in such a way that it is distributed as well as possible and occurs without creating a noticeable air flow.
  • the valve disk typically prevents the direct, straight exit of the air in the direction of its previous flow and ensures that the air flows along a circumferential annular gap (between the edge of the valve disk and the heating element housing) in a defined angular range relative to the Inflow axis flows out.
  • the interaction of the outer collar of the heating element with the diameter of the valve disk, its setting position and its shape (which can differ due to design variants of these components) can influence the angular range of the air outlet flow and the throttle effect.
  • the outlet angle and/or the throttling effect can be adjusted to the needs of the respective room due to the variability of the distance between the valve disc and the heating element housing.
  • connection between the valve disk and the heating element housing can be made in particular via a plug-in mechanism, which preferably has latching steps.
  • the valve disk can then be mounted at a specific distance in a defined and reproducible manner.
  • the plug-in mechanism can be realized, for example, by a cross dome on the valve plate and an associated cross dome receptacle on the heating element housing (or vice versa).
  • the invention relates to a basic valve heating element in which a decorative collar is arranged around the connection housing and/or around the heating element housing, which decorative collar forms the transition to the wall.
  • a separate decorative collar that is not connected in one piece to the connection housing or the heating element housing has the advantage that the decorative collar can be selected independently of the aforementioned components and can also be replaced if necessary.
  • a decorative collar that fits optimally from an aesthetic point of view can be used, or a decorative collar that is damaged or has gone out of fashion can be easily replaced with a new decorative collar at a later point in time.
  • the invention relates to a basic valve heating element with an annular gap limiter, which is arranged in an adjustable manner at the air outlet opening of the heating element housing and prevents air from escaping in certain directions.
  • the annular gap limiter can be of any shape and design. As its name suggests, however, it will generally serve to delimit an annular gap which is formed, for example, between the heating element housing and a valve disk. Accordingly, the annular gap limiter is preferably arranged in the air outlet opening between the heating element housing and a valve disk. The air flow can be shaped as required by the annular gap limiter by blocking it in certain directions. Due to the adjustability of the Annular gap limiter, the position of these directions can be optimally adapted to the building conditions.
  • the annular gap limiter is preferably arranged in latching steps so that it can rotate about the air outlet axis of the heating element housing. A defined position of the annular gap limiter is achieved by the locking steps, which can also be easily reproduced.
  • connection housing for connecting an air duct. Since in practice there are air ducts of different dimensions and geometries, an adapter is advantageously provided as a separate component, which causes the transition from the coupling part of the connection housing to the respective air duct. In this way, the coupling part on the connection housing can remain the same, and only different adapters have to be provided in order to be able to flexibly connect the valve heating element to different air ducts.
  • the invention relates to a base valve thermal element having a housing that can be used in place of the connector housing and/or the thermal element housing and allows air to flow in at least one direction.
  • This housing is referred to below as a "passive housing” because it is designed for the passive flow of air (i.e. without actively heating it).
  • the passive housing provides a system of components that can be combined to form an (active) valve heating element or a (passive) supply air and/or exhaust air valve element.
  • the manufacturing costs can be reduced by using the same components.
  • the components visible from the outside are preferably used consistently, so that an active valve heating element and a passive supply air and/or exhaust air valve element have the same appearance.
  • the passive housing can have a receptacle for a (preferably exchangeable) filter element.
  • a (preferably exchangeable) filter element is advantageous, for example, if an exhaust air connection is to be implemented in a place such as a kitchen, where air pollution often occurs.
  • valve heater 100 Illustrated in the figures is an exemplary embodiment of a valve heater 100 in accordance with the present invention.
  • the valve heating element serves to enable controlled air entry into a room, for example of air preheated by means of geothermal heat or by an air/air heat pump.
  • a valve heating element In order to ensure adequate heating of the room when the pre-temperature of the supplied air is low - for example due to cold outside temperatures or low power provided by the heat pump - a valve heating element typically contains an electric heating register with one or more heating segments (as the smallest active heating units) which flows through them can heat air.
  • PTC resistors the resistance of which increases with increasing temperature, the heating output can be adjusted to the air flowing through the valve heating element in a self-regulating manner.
  • three tensioning claws 120 are arranged on the rear outer edge of the connection housing 110 and distributed uniformly around the circumference. In a rest position, these are pivoted radially inwards, so that they bear against the connection housing 110 . In order to keep this starting position safely on the way from the manufacturer to the place of installation, a slight embossing of the traction claw contact surface is preferably provided to secure the position. This can be designed in such a way that it is "skipped" by about half a screwdriver turn in the opposite direction to the tightening direction (counterclockwise) and then tightening it (clockwise).
  • this interaction is also possible through a different contouring (pairing) of claw socket and claw contour by overcoming the breakaway torque in the tightening direction of the claw screw. This means that releasing the claw in the opposite direction can be replaced by overcoming the breakaway torque of the claw.
  • the pull claws 120 are pivoted radially outwards, so that they protrude beyond the radius of the connection housing 110 . Furthermore, the tension claws 120 are mounted with a thread on a tension screw 121 which runs in the axial direction and is accessible from the front of the connection housing 110 . By turning this tension screw 121, the axial position of the tension claws 120 can therefore be changed.
  • connection housing 110 can be easily and securely fastened in the opening of a building (cavity) wall.
  • the connection housing 110 is first inserted (with the tension claws 120 in the rest position) through the prefabricated, circular opening in the wall panel that is as precisely fitting as possible, then the tension claws 120 are swiveled radially outwards into the holding position, whereby they grip the wall panel from behind, and finally they are pushed through Tightening the tension screw 121 pressed against the wall plate from the inside in order to clamp the connection housing herewith.
  • a flange 114 ( figure 6 ) of the connection housing 110 ensures the necessary back pressure.
  • FIG 6 shows a top view of the connection housing 110.
  • This consists of a body 111 with a circular central opening for the air flow.
  • a line duct 117 in the form of a separate, structurally separate chamber into which the cable entry 112 opens.
  • two latching hooks 118 are provided, on which a terminal block 116 without tools can be fastened by latching.
  • the connection strip 116 can also be attached to a screw hole 119 in the cable duct 117 .
  • connection strip 116 e.g by means of plug-in connections or screw connections.
  • connection strip 116 After the connection strip 116 has been connected, it is fastened to the snap-in hooks 118 and the cables are housed in the cable duct 117. Since the cable duct is structurally separated from the air flow, overheating of the components there is impossible. It is therefore not necessary to make the mains connection using special insulation, for example made of Teflon.
  • figure 8 12 shows how terminal strip 116 is electrically connected to a pin strip 132.
  • FIG. This connection or plugging together of terminal strip 116 and pin strip 132 takes place automatically when the heating element housing 130 and connection housing 110 are assembled (the two housings being firmly connected to one another, for example by means of screws).
  • the glow lamps 131c can be seen from the front side of the heating element housing 130 through corresponding openings, so that the user can check the correct function or wiring of the circuit board.
  • figure 11 shows the arrangement of the control circuit board 131 in the heating element housing 130. Furthermore, a central, approximately cross-shaped opening can be seen, in which the electric heating register made of PTC elements (not shown) is to be arranged. Due to the cross shape, the actually circular surface of the air duct is optimally exploited.
  • the cross-shaped opening also has locking cams 134, with which the heating register can be easily installed and removed without tools and is held securely.
  • the printed circuit board is also advantageously snapped in and out without tools, for example by being held by locking cams.
  • figure 11 also shows that the control circuit board 131 and the electrical connections for the heating register are arranged on adjacent sides of the heating register, contact protection webs 133 to prevent short circuits being visible on the side of the connections.
  • the PTC heating segments of the heating register accordingly run transversely and parallel to one another from the connections to the opposite side of the heating register, ie in figure 11 horizontal or parallel to the control board 131.
  • the arrangement of the control board and heater connections on adjacent sides of the heater allows the footprint of the heating element housing to be kept compact despite the non-square shape of the heater.
  • FIG 12 shows a top view of the heating element housing 130 with a protective grille 136, which is arranged in the air flow duct in front of the heating register (not shown). It can also be seen that the cylindrical heating element housing 130 is fastened in the connection housing 110 (preferably by screwing), with the connection housing consisting of a substantially cylindrical body which has a peripheral flange 114 on its front edge on the room side for resting on the outside of the Ceiling or wall has (as a counter bearing to the tension claws).
  • the flange 114 has the shape of a square with strongly rounded corners, the straight flange edges can additionally have notches in the middle in order to ensure the exact horizontal/vertical alignment of the housing in a building wall facilitate, which is particularly advantageous with rectangular collar shapes, since their outer edges should be aligned as exactly as possible parallel to other reference edges of the room.
  • the flange 114 of the connection housing 110 towards the space is preferably through the Figures 1 and 2 illustrated decorative collar 160 covered to direct the exiting air between collar and plate and allow a more aesthetic appearance.
  • the axial spacing of the decorative collar from the flange of the connection housing 110 can preferably be adjusted within certain limits in order to be able to form an adjustable shadow gap with the building wall. The adjustment can take place, for example, by turning the decorative collar 160 mounted on a helical line on the connection housing 110 .
  • the decorative collar can be designed in such a way that it can accommodate lighting on its inside, for example in the form of LED strips.
  • a corresponding hole can be provided in the flange collar of the connection housing.
  • the heating element circuit and the lighting circuit can be switched separately.
  • the collar shape and color allow the lighting to be designed as effect or emergency lighting. By adjusting the shadow gap, the light in the vicinity of the collar can be directed onto the wall or ceiling surface.
  • the protective grid 136 prevents a user from touching (in the case of non-insulated PTC heaters) electrically conductive (i.e. live) parts of the heater.
  • the heating registers themselves could be electrically insulated, e.g. as PTC chips insulated with Kapton foil, so that upstream contact protection could be dispensed with.
  • the disadvantage of this variant is that the electrical insulation would also represent a thermal barrier at the same time, at the expense of a reduced power density as a result.
  • the protective grille 136 through which the heated air flows into the room, is typically covered by a valve disc (or other type of valve attachment) for directing and metering the air flow.
  • figure 13 shows such a valve disk 150 in a view of its rear side, which faces the protective grille 136 in the assembled state.
  • the basically circular valve disk 150 has a cross dome mount 152 in the middle, which consists of four angle plates, each rotated by 90° to one another and protruding perpendicularly from the valve disk, which form a cross-shaped slot between them.
  • latching steps 154 are preferably arranged on the insides of this slot, and one of the walls of the cross dome receptacle 152 has a recess 153 so that the valve disk can only be in a certain alignment ("12 o'clock position") with the heating element housing can be connected. In this way, a reproducible attachment of the valve disk 150 can be ensured.

  • Latching cams 138 arranged on the left and right on the cross dome 137 can interact with the latching steps 154 of the cross dome receptacle in order to fix a specific axial position of the valve disk relative to the protective grille and make it reproducible.

  • the passive housing 191 is designed to allow air to flow in at least one direction with the lowest possible flow resistance. It contains no heating register, no protective grille, and no electrical connections.
  • a bayonet ring 115 For connection to an air duct, it has the usual or already described means, for example, as shown, a bayonet ring 115. It is preferably attached to the wall using the explained system of tension claws 120 with tension screws 121.
  • an exhaust air valve element 190 is to be implemented with the passive housing 191
  • this can optionally be equipped with a filter element. This can be placed under the valve disk 150, for example.
  • figure 24 shows a section through the element 190 in the embodiment as an exhaust air valve element with a filter fleece 193, through which dust, vapors, fats and the like can be retained when extracting exhaust air (eg from a kitchen or a bathroom).
  • a grid 192 is preferably provided.
  • figure 25 shows a grid designed as a spoked wheel 192 in a plan view of the exhaust air valve element 190 with the valve plate and filter element removed.
  • the spoked wheel 192 is fastened to the passive housing 191 in a latchable manner, for example.
  • it is preferably provided with a cross dome in the middle, to which the valve disk can be fastened in the manner known from the valve heating element 100 .
  • the filter element 193 is typically disk-shaped with a central hole for the passage of the cross dome. Optionally, it can be radially slotted so that it can be changed without removing the valve disk when the disk gap is sufficiently wide.
  • figure 26 shows a top view of the visible outside of a supply air valve element, which has a throw valve 150' and does not contain a filter.
  • a silicone foam disk (not shown) of a suitably selected diameter can optionally be arranged between the long throw valve 150' and the associated spoked wheel.
