Definitions

  • Ventilation arrangements of this type have long been known in various embodiments.
  • the walls of the collecting duct consist of strip-shaped sheet metal parts which are connected to one another via aluminum profiles.
  • the reinforcements are also formed in the region of the edges of the channel openings in this known construction. In this way, the edges have a high stability and enable a well-sealable system for the inserts, such as the separators, sealing panels or the like.
  • the object of the present invention is to create a completely new type of ventilation arrangement which, with a simple structure and comparable stability, does not require the use of profiles.
  • reinforcements are formed in one piece from the material of the collecting duct by means of bevels directed towards the collecting duct interior.
  • the invention is based on the idea of replacing the complex profiles in the area of the edges by folding. Bends for the purpose of stiffening or stiffening in sheet metal processing are already known. However, the prevailing opinion is that bevels on the edges of sheet metal workpieces do not enable such precise alignment and flat surface formation as is possible, for example, when using extruded aluminum profiles. These concerns apply in particular to long lengths of bend, as they have to be realized with collecting ducts of the type under discussion here, and in particular when the bends are directed inwards, i.e. are arranged in areas where space is limited.
  • the bevels can be designed in any suitable manner to suit the respective application.
  • a particularly advantageous embodiment results, however, if the reinforcements formed in this way are formed from the material of the collecting channel by being folded twice by 90 in each case.
  • ventilation arrangements of the type under discussion here comprise not only a single straight collecting duct, but rather a collecting duct which is composed of at least two straight duct sections which are usually adjoining one another at an angle of 90. With such an arrangement, it is advantageous if the channel sections in the connection area facing one another are cut to a narrow extent and are preferably butt welded to one another. In the case of ventilation arrangements of the known type, these connection areas have also previously been designed with connecting profiles, the arrangement and sealing of which, however, always required a certain amount of effort in relation to the collecting duct wall.
  • the channel sections of the collecting channel can be precisely adapted to the respective spatial conditions, in particular with regard to the arrangement of the hotplates.
  • the collecting duct will consist of four straight duct sections which are connected to one another at an angle of 90 to form a rectangular or square ring duct arrangement.
  • the embodiment according to the invention is basically suitable for collecting channels of any cross-section.
  • the cross section is essentially triangular and the channel opening is arranged in the region of the hypotenuse of the cross section in order to form an obliquely extending arrangement which is directed essentially towards the center of the room.
  • a collecting duct which is composed of a total of four duct sections 1, 2, 3 and 4, which are connected to each other at an angle of 90 to form a rectangular ring duct arrangement .
  • Each channel section 1 to 4 consists of three side walls 5, 6 and 7, which results in an essentially triangular cross section of the collecting channel.
  • the arrangement is such that the side wall 6 forming a cathete in the ceiling area of the kitchen, i.e. runs horizontally, while the adjoining outer side wall 5 parallel to the wall of the kitchen, i.e. is oriented vertically, and the side wall 7 which forms the corner of the triangular cross-section runs obliquely, i.e. faces the kitchen interior.
  • the collecting duct formed from the four duct sections 1 to 4 is connected to a suction air source (not shown) via a connecting piece 8, as indicated by an arrow 9 in FIG. 2.
  • each channel section 1 to 4 facing the kitchen interior is provided over the entire length of the respective channel section with a channel opening 10 which extends essentially parallel to the longitudinal extent of the respective channel section and is provided with a reinforcement 11 in the area of its edges.
  • the reinforcements 11 are formed by bevels 12 (see FIG. 2) directed towards the interior of the collecting duct, which are made in one piece from the material of the collecting duct, i.e. consists of the material of the respective side wall 7.
  • the reinforcements are formed out of the material of the collecting channel by being folded twice by 90 in each case.
  • the channel opening 10 is covered by different inserts.
  • some of these inserts consist of so-called closing orifices 13, which cover the channel opening 10 in those areas in which no exhaust air flow is desired.
  • So-called separators 14 are inserted between the closing screens 13, via which particles or droplets contained in the exhaust air can be separated and added to a collecting channel (not shown) or the like.
  • These separators 14 can be designed in many different ways. Such a separator is described, for example, in German Patent P 27 20 201.
  • the bevels 12 can be designed in such a way that a precisely aligned and sealable support for the inserts can be formed even over great lengths.
  • the bevels 12 can, of course, be designed in any manner and, in addition to their support function for the inserts, may also perform a stop or centering function.
  • the side wall 7 facing the kitchen interior is folded several times in its upper area so that a support for the ceiling panels 15 is formed. This results in a more trapezoidal cross section for the channel sections.
  • trapezoidal or other shaped channel sections can be used in the area of the upper end of the side wall 7, which are used for feeding fresh air or for receiving lighting fixtures or the like.
