Definitions

  • the present invention relates to a blower arrangement for use in a Air conditioning system, e.g. is used for copying / duplicating machines.
  • Air conditioning systems usually include a blower system that helps them the cleaned and cooled air or another gas is available for use in the apparatus close.
  • An air conditioning system is a precisely working, expensive subsystem in one Copy / duplicating machine. It is important to increase the efficiency of the air conditioning system get and improve as possible while continuously improving and Cost reduction measures are carried out.
  • the air conditioning system uses one or more Air filter chambers, which include one or more blower systems.
  • the used Blower systems increase the air pressure in the chamber (s) so that the air passes through filters is pressed to remove particles. The filtered air is then from the blower system out of the machine and / or for reuse in other parts of the machine guided.
  • the attachment of the blower itself within the blower arrangement of the Air conditioning system is of particular importance.
  • the blower arrangement has an entry ring through which the air is drawn into the blower and then from the blower into the desired direction (s) within the air conditioning system.
  • the fan should be as close to Entry ring.
  • the space between the flow direction Subsequent entry edge of the entry ring and the blower itself should be approximately 0.15 cm (0.06 inch) with the gap tolerance no more than about 0.05 cm (0.02 Inches) should be. If the gap is too small, there is a risk that Fan hits the inlet ring during operation. However, if the gap is too large, leads this to air turbulence. Both affect the operating efficiency and the lifespan of the Machine.
  • blow assemblies have been made from a variety of items, as later is described in more detail.
  • the assembly of these parts was time consuming and expensive.

  • the entry ring support element also has a number of integrated standing supports or columns that are used to Blowers are aligned and have a free end. Every support comes from Back of the support element and ends in a free end.
  • the supports and their free ends define the volume of space or the area in which the fan operates.
  • a blower support element is attached to the ends of the supports, including a lower one Closure element that is located on the lower side of the blower between the Blower support element and the entry ring support element is located.
  • blower arrangement is further characterized in that, in contrast to the prior art has no side elements provided with openings. This is shown in detail in the description of the prior art.
  • the unit consisting of the entry ring and the entry ring support element is a single, integrated component in contrast to the two individual parts according to the prior art, the one Make manual assembly necessary.
  • This component also has a variety of standing Supports that are part of the entrance ring support surface and each have a free end to have. These supports and their free ends define the volume of space or the area in which the blower can be operated.
