Definitions

  • the invention relates to an insect protection device for a fan arranged in or on a wall, a building wall or a ceiling according to the preamble of claim 1.
  • a venting device for rooms by inner and outer walls known, wherein at least one bore is guided by the wall.
  • a pipe is pushed through this hole, which can accommodate at its ends statements against insects, rainwater and / or a closure for the regulation of air passage.
  • the fan to the interior facing side of the wall on a connector, which is inserted by means of elastic ribs in the tube and is held immovable.
  • a pipe section can also be inserted by means of elastic rings holding in the tube, which has a holding device into which an insect screen can be placed.
  • the insect screen or the insect screen can be mounted in a known method only from the outer wall. Both the installation and subsequent maintenance work on the insect screen can only be tackled from the outside, as the insect screen is not accessible from the inside. Furthermore, due to its manner of attachment to the fan and its material after maintenance, the insect screen can not be reused, which requires an additional cost of replacement.
  • insect screens are known to be familiar to fans, which are operatively connected inserted into the weather protection applied to the outer wall. This insect screen is difficult to access only accessible from the outer wall, in exchange on the fan or weather protection cumbersome and can not be cleaned after contamination. Remedy creates a renewal, which also proves to be costly.
  • the invention is therefore based on the task to enable assembly and disassembly of an insect protection device in or on a wall fan, which fixes all the above disadvantages, is inexpensive and easy, fast, safe and precise way with little space cleaning allowed with reuse.
  • an insect protection device for a fan on a wall or a ceiling or in a wall or a ceiling is proposed, with a wall having through the bore, which forms an air passage for an air passage of air flow for exhaust air and / or supply air.
  • a ventilation tube is inserted through which the air can pass.
  • the ventilation pipe connects the arranged in an interior to an inner wall components of the fan with the outside on an outer wall having components of the fan.
  • the insect protection device is integrally formed. With one-piece construction of the insect repellent device all essential components for protection against invasion of insects and for mounting in an assembly are included and can be mounted with a single handling in the fan and also disassembled for the purpose of maintenance and cleaning.
  • the assembly may be made in several parts prior to assembly of the insect protection device, which connects with mounting by positive and / or non-positive connection as a one-piece component.
  • a one-piece assembly of the insect protection device is made of a material conceivable. Reuse after cleaning the insect repellent device is therefore possible without problems and from the following advantageous features. Effort and costs of a new insect screen are therefore unnecessary.
  • the insertion or removal of the insect protection device is preferably carried out from the side of the interior.

  • the end position of the insect protection device determines the exact arrangement in the Ventilation pipe. Since the wall according to the type of construction of a building has different width walls, a uniform distance measure can be determined with a fixed position of the insect protection device in the ventilation pipe from the inner wall to the insect protection device. With a fixed position, further components for perfecting the fan in the ventilation pipe can be used without varying the variety of individual components of the same dimensions in different wall thicknesses.
  • a simple assembly and disassembly with a secure hold of the insect protection device is achieved by simple and inexpensive means advantageously characterized in that the end position of the insect protection device is a detachable connection, which establishes an operative connection between the inner wall of the vent pipe and an outer surface of the insect protection device.
