Definitions

  • the frame consists of metal parts, for each frame size and the respective application will be produced. For this reason, the framework is proportionate expensive.
  • the dryer unit In the dryer unit according to the invention, they are parallel to the sides of the frame Sections of a hollow profile formed, as it is for manufacture of the main moldings of heating strips is used. You can thus one and the same hollow profile material use for different purposes what warehousing and purchase price influenced favorably. Because that used Hollow profile next to a closed center Channel that is used as an air channel in the groin main bodies is used, has further ribs the hollow profile high mechanical strength.
  • the orientation specified in claim 2 to the heating strips parallel frame parts is high in terms of Mechanical resilience of these frame parts is an advantage: With this orientation lie those carried by the hollow profile Blowing ribs at a distance parallel to the frame plane, so that one against deflection by the blowing ribs improved area moment of inertia.
  • FIG. 4 is constructed according to a similar principle as that in the Figures 1-3 shown infrared heating bar.
  • Functional equivalent main ledge components are included provided the same reference numerals and will not be repeated described in detail, even if they are in structural Differentiate details from the first embodiment.
  • the wall segments 46 there are two in the top of the groin main body milled rectangular windows 44, and in this wall segments 46 are inserted, which is a smooth Continuation of both the air duct 16 and the outer surface of the housing guarantee. To do this, the wall segments 46 an inner surface 48 curved according to the air duct 16 and a flat outer surface 50. In the outer surface 50 is a cable groove 52 inserted into a cable hole 54 leads, which opens out to the inner surface 48.
  • the IR heating strips 6 via the adapter parts 34 with the frame parts 116 and 118 connected.
  • the same adapter parts 34 are also between the ends of the frame parts 122, 124 and the frame parts 116 and 118.
  • the frame parts 122, 124 are also with blowing channels 22 trained. So you can do the same Profile sections optionally as a strip main body for IR heating strips or use as frame part 122 or 124.
  • the wall plate has 128 openings 138, via which it connects with the longitudinal channels 16 the IR heating strips 6 or the hot air heating strips 8 in Connection is established.
  • the openings 138 are each of four through openings 140a, 140b, 140c, 140d for Fastening screws (not shown) surrounding the Push through adapter pieces 34 and into the ends of the IR heating strips 6 are screwed in or with the adapter parts 126 are screwed.
  • each heating strip 142a, 142b provided for the attachment of Wall plate segments serve, as described in more detail later becomes.
  • the wall plate 128 has openings in its end sections 144, the openings 138 in the geometry correspond, but are tilted by 90 °, so that they are with the longitudinal channels of the frame parts 122, 124 swear.
  • the openings 144 are of through openings 146a, 146b, 146c and 146d, at which the frame parts 122, 124 are screwed tight.
  • the end pieces 136 are made of a hollow profile material Cut to length, which is that shown in FIG Cross section.
  • a web 170 runs from the upper leg 158 up, in which another mounting hole 172 and a horizontal receiving groove 174 in FIG. 13 are provided is. Similarly, in the thickened end portion of the lower leg 160 a mounting hole 176 and a receiving groove 178 is provided. About the mounting holes 172, 176, whose distance is the distance between Corresponds to through openings 146a and 146c or 146b and 146d, can the end pieces 136 additionally with the wall plates 128, 130 can be connected.
  • FIG. 14 shows an orientation of the wall plate segments, how to implement the lower wall plate 132 is used in Figure 15 is an identical, however Wall plate segment rotated by 180 ° is shown as it serves to realize the upper wall plate 134.
