Definitions

  • the invention relates to a clean room laboratory fume cupboard with a work space open on one side and a blower connected to it, according to the preamble of protection claim 1.
  • the object on which the invention is based is to design such a clean room laboratory fume cupboard, which is used, for example, in chemical laboratories and the like, in such a compact manner that it has, in particular, the same dimensions as a standard laboratory fume cupboard, so that it can be interchanged with the clean room laboratory fume cupboard according to the invention.
  • the fan In the clean room laboratory fume cupboard according to the invention, the fan generates a laminar air flow, the air in the work space conducts.
  • the blower On the negative pressure side, the blower sucks in an air flow through the at least one nozzle from the part of the open side of the work space opposite the blower and from the rear, that is to say the rear area of the part of the work space opposite the blower, these air flows going to the blower via the hollow double side walls and double back walls.
  • the fan divides all of the intake air into an airflow that escapes into the exhaust air opening and the airflow that goes into the work area.
  • the exemplary embodiment of the clean room laboratory fume hood according to the invention shown in FIGS. 1 to 3 has a blower, for example a fan 9, which generates an air flow which, filtered by the main filter 1, blows clean air into the work space 12 (air flow II).
  • a blower for example a fan 9, which generates an air flow which, filtered by the main filter 1, blows clean air into the work space 12 (air flow II).
  • a further air flow I through the nozzle 8 into the Extracted suction, which is provided on the part opposite the fan 9, ie in the present exemplary embodiment the lower part of the working space, on the open side.
  • Part of the laminar air flow II is sucked off into the nozzle 8, the exhaust air being sucked up from the nozzle 8 via the two hollow double side walls of the working space 12 to the fan 9.
  • the remaining laminar flow from the work space 12 is sucked through the hollow double rear wall of the work space 12 to the fan.
  • the fan presses all of the extracted air into a pressure chamber 11.
  • the fan 9 is on the pressure side, i.e. via the pressure chamber 11, connected to an exhaust port 5 and to the work chamber 12.
  • the compressed air flow from the blower 9 is therefore divided into an air flow III to the exhaust port 5 and the laminar air flow II, which goes into the working space 12 via the main filter 1.
  • 25% of the air in the exhaust air connection 5 and 75% preferably go into the work space 12 as a laminar air flow II.
  • the clean room laboratory fume cupboard shown in the drawing is further provided with a lamp 2, a rectifier 3 and an exhaust air filter 4, via which the exhaust air goes to the exhaust air nozzle 5.
  • the main filter 1 can be folded down about a horizontal axis in the work space 12. This has the advantage that the main filter 1 and the exhaust air filter 4 can be easily replaced without having to detach a separate plate in the front area.
  • the exhaust air filter 4 can be replaced from below, which is absolutely necessary, for example, in the case of a fume cupboard that is veneered to the ceiling.
  • a vertical sliding window 6 is provided on the clean room laboratory fume cupboard.
  • seals 13 are provided in the area of the work space 12 on the open side, as schematically shown in Fig. 4 is shown.
  • the sliding window 6 is guided in the area of the open side of the working space 12 between these seals 13 and guideways 14, which have areas which are curved or protrude in the direction of the seals 13. Through this guide, the sliding window 6 is pressed firmly against the seals 13, which ensures the tight seal.
  • the clean room laboratory fume hood is provided with a seamless table top 7 made of stainless steel, which is preferably raised by about 50 mm on both sides and on the back.
  • the nozzle 8 In the front area of the table top 7, i.e. In the area of the open side of the working space 12 there is the nozzle 8, which can preferably be opened.
  • This rear wall suction 10 is, for example, 50 mm above the table top 7. 2/3 of the air volume is sucked off via the nozzle 8 and guided upwards over the hollow double side walls.
  • the nozzle 8 is raised in relation to the table top 7 and the trough underneath can be cleaned after opening the nozzle 8 without having to empty the fume cupboard.
  • the clean room laboratory fume cupboard according to the invention has the advantage that, due to the extraction via the exhaust air ducts on the left and right side and the rear side, there is a high degree of variability in use.
  • the clean room laboratory deduction can thus be easily adapted to the different applications.
  • the exhaust air duct is separated.
  • the rear exhaust slot 10 is connected to the exhaust port 5, so that the exhaust filter 4 is no longer required.
  • the exhaust air guided in the side walls is blown into the working space 12 with the aid of the fan 9.
