Definitions

  • the suction power of the air cleaning device by increasing the speed of its fan; the increased suction power is, however, paid for by considerable noise problems, which have an adverse effect, in particular when using the air purification device as a kitchen extractor hood.
  • the suction power is increased essentially only in the area near the blower and not in the area of the enlarged suction opening.
  • the object of the invention dealt with here is to solve the problems associated with the enlargement of the suction opening in a simple manner effectively in air purification devices of the type described in the introduction.
  • this object is achieved by an additional blower assigned to the movable air guiding devices and which can be activated by the air conveying device of the device.
  • the additional fan is located in the immediate area of the section of the suction opening enlarged by the movable air guiding device.
  • the additional fan is designed as a cross-flow fan.
  • the additional blower can be controlled via sensors.
  • a kitchen extractor hood designated overall by 10 in FIG. 1, has a housing 11 which, in the usual way, has air conveying devices in the form of a blower 12 and various filter devices in the form of grease filters 13, lighting 14 arranged near its suction opening located below and a drawer-like pull-out 15.
  • the extract 15 serving to enlarge the suction opening of the kitchen extractor hood 10 is equipped in the usual way with operating elements 16 located on its top side, which are accessible in the extended state and with the aid of which the fan drive can be switched on and, if necessary, additional functions of the extractor hood are switched can be.
  • An additional blower in the form of a cross-flow blower 17 is assigned to the extract 15 serving as a movable air guiding device, which blower lies in the immediate area of the enlargeable section above the suction opening and extends over its full width.
  • a bulge 18 which extends near the suction opening over the front side of the housing, is used in a known manner, various switching functions of the kitchen extractor hood 10 can be monitored and controlled.
  • FIG. 4 shows the dependence of the noise behavior of the blowers R1, R2 and Q as a function of the air volume V ⁇ conveyed. It this shows the favorable low noise increase resulting when the cross-flow blower is switched on and its jarring noise development.
