Definitions

  • FIGA A first figure.
  • the present invention relates to improvements in convectors for heating rooms, of the kind which is provided in a heat chamber extending above the convector, heating being effected by blowing in fresh air through the convector.
  • the invention is substantially characterized in that in an inlet for fresh air disposed below the convector there is provided a device provided with holes and rotatable in such a manner that the amount of air passing through, when the device is turned, is blown wholly or partly through the heat chamber and the convector or entirely past the said chamber and the convector, whereby the supply of heat to the room to be heated is regulated.
  • the rotatable device may consist of a roller or the like through which holes are made in one or more oblique lines in relation to the axis of rotation of the roller, so that the amount of air through the convector is continuously changed, when the roller is turned.
  • An opening for the air of the room may be so made in a screen or the like provided in front of the heat chamber that no air flows through the convector, when the whole amount of fresh air is blown through a channel which is formed between the heat chamber and the screen.
  • one or more holes may be made in a conduit provided below the heat chamber or the convector, one or more nozzles being so connected to the hole or holes, that the amount of air passing through the holes can be conveyed wholly or partly through the heat chamber with the convector or entirely past the heat chamber with the convector, by adjusting the direction of blowing of the nozzles.
  • FIG. 1 shows the convector seen from the side, arranged for two different positions of emitting heat.
  • Figures 3 and 4 show two different rollers and
  • Figures 5 and 6 show another embodiment of the roller in two different positions of adjustment.
  • Figures 7 and 8 show two other embodiments.
  • Fig. 9 discloses the manner in which the roller of Fig. 4 is mounted in the casing for rotary movement.
  • Fig. 10 shows a further means for rotating the roller of Fig. 1.
  • the numeral 1 denotes a chamber or conduit for fresh air, the temperature of which may be equal to or lower or .higher than the temperature in the room A for which the 'ice fresh air is intended.
  • the fresh air passes through a conduit 1b, from a central source (not shown) to the chamber 1, from which chamber the air passes through a rotatably adjustable roller 2 located in an aperture 2b.
  • the roller is provided with holes 2a for the passage of the fresh air.
  • the chamber 1 defines the lower portion of a casing 3:; having front wall 3b facing the room A, rear wall 3b facing wall B of the room and two side walls 30. At the top, the casing is provided with a grate 21. In the front wall 3b, forwardly of a common space 1a within the casing is an aperture 3 for air from the room A, which air is drawn through the casing by the ejector action of the fresh air forced through the holes 2a in the roller 2.
  • the casing is divided into two vertical channels 5 and 6.
  • a convector 4 is positioned at the lower end of the channel 5 and the portion above the convector constitutes a heat chamber which provides a chimney action.
  • the front wall of the channel 6 is formed by wall 312 of the casing.
  • the roller 2 When apparatus according to the invention is used in a room A, the amount of air must be adapted to the normal supply of ventilation. In certain cases, for example if many people are in the room, a much greater amount of fresh air is desired.
  • the roller 2 is provided partly with a series of holes with larger total area and a series of holes with smaller total area, arranged, for example in in relation to these holes.
  • the ventilation is to be normal Figure 5
  • the roller 2 is turned so that the fresh air is blown through the smaller holes 7, the larger holes 8 being shut by means of screens 9 which are secured in the casing and contact or rest against the roller and in'the position shown, cover the holes 8.
  • the need of ventilation is great ( Figure 6)
  • the roller 2 is turned clearing the holes from the screens so that the fresh air is blown through the larger holes 8, with the smaller holes. 7 then being covered by the screens.
  • the roller 2 is carried by a shaft 13 mounted in the walls 30 of the casing and a portion of the shaft extends beyond one of the walls as shown in Fig. 9.
  • Au operating button 14- may be fixed to the projecting. portion of the shaft 13 to turn the roller, or a lever 15 can be attached to the roller with the other end projecting through the aperture 3 in the casing to permit manipulation of the roller as in Figs. 1 and 10.
  • a nozzle 10 preferably of elastic material, is forced on the edges of the holes 2a provided in the conduit 1.
  • the nozzles By bending the nozzles .10 to the position indicated by dashed lines the fresh air can be passed entirely to the channel 6, whereby desired intermediate positions may be obtained.
  • the nozzles In order to attain a continuous change of the air through the convector the nozzles can be fastened to one (or more) wall portion of the conduit 1, the said nozzles being arranged in rows forming an angle with the longitudinal axis of the conduit.
  • the wall portion may be plane, and then the change of the supply of air is obtained by displacing the said portion, but it may be arcuate, and then the change is obtained by turning the said portion.
  • a screw 17'- is arranged in a window board 16 and is provided with an operating button above the window board.
  • a rod 19 extends downwardly from the screw in the channel 6 with the lower end of the rod being connected to the nozzle by a lever 20. Manifestly, the rotation of the button will raise or lower the rod thereby moving the nozzle 10 in the proper direction.
  • the embodiment shown in Figure 8 has an elastic wall portion 11 attached to the conduit 1.
  • the nozzle 10 may be stiff, as the elastic portion permits change of the direction of flow of the nozzle, so that the fresh air can be successively changed from full quantity through the eonvector to full quantity through the channel 6.
  • the size of the opening 3 is so adapted that the subpressure inside the opening obtained through ejector action and the chimney action neutralize each other as much as possible, or the nozzles may be provided with one or more screens 12 which prevent inner circulation (Figure 8).
  • the hot water conduit has no valves several convectors may be connected in series with each other.
  • the conduit system for hot water one tube and all the valves may be dispensed with.
  • An assemblage for heating rooms comprising a casing constituted by interconnected front, rear, side and bottom walls, partition means within the casing intermediate the front and the rear walls and extending parallel to the front and rear walls providing two channels in the upper portion of the casing with the lower ends of the channels terminating above the bottom wall, and the upper ends of the channel communicating with a room to be heated, further partition means within the casing below the lower ends of said channels and above the bottom wall and extending between said front, rear and side walls in parallelism to the bottom wall defining a common space between the further partition means and the lower ends of the two channels, a radiator arranged in the lower portion of one of the channels, means for supplying fresh air under pressure to the space formed by the bottom wall and the further partition means, the further partition means being provided with an aperture therein, an air discharge means, means movably mounting said air discharge means in said aperture for directing a stream of fresh air across said common space, control means for moving said air discharge means for directing said air stream into the lower end of either of said channels, and
  • said air discharge means includes a roller having holes extending therethrough, and bearing means on the roller .rotatably mounting the roller in the side walls of the casing.
