Definitions

  • the invention relates to a method for operating a ventilated extractor hood according to the preamble of claim 1 and to a ventilated extractor hood according to the preamble of claim 2.
  • a ventilated extractor hood other sources of haze and dust.
  • the filtered air is blown into the working space via a circulating air opening in the hood housing, which usually points obliquely upwards.
  • the area of the intake filter, which is usually upstream of the fan, is approx. 20 - 30 times the air circulation opening.
  • the intake fan requires a delivery volume of up to 500 cbm / h, which naturally causes considerable flow noise. With such hoods, the trend is towards even higher delivery volumes.
  • DE-OS 22 59 670 relates to an exhaust hood with an air curtain, in which the air extracted from the stove is partially discharged to the outside via an exhaust duct and a pressure chamber maintained by the suction fan under excess pressure causes an air curtain to be drawn by the suction of the supply air taken inside and up.
  • the blower must be dimensioned so strong that the air curtain extends at least to the top of the stove in order to perform its locking function, and that the pressure chamber is kept under such a high pressure that the air curtain is formed.
  • the fan sucks the air supply flow (haze over the hearth area), and this supply air leads to a considerable extent by thesecure g sö réelle outside.
  • the object of the invention is to achieve a circulating air hood with the lowest possible blower output or delivery rate and the greatest possible effectiveness, to be able to manufacture the hood in particular with a significantly lower overall height than with known, comparable hoods, to keep the flow noise significantly lower compared to known hoods to circulate the air to be cleaned faster than before and. to prevent primary vapors from escaping into the work area.
  • the suction effect of the blower is considerably supported, so that the blower power can be kept extremely low and, due to the lower air throughput, the flow noise can be reduced to such an extent that that occurring during the operation of the hood Noise is no longer perceived as disturbing.
  • the additional upflow and the support of the suction effect of the blower also ensures that the exhaust air forming the upflow does not reach the kitchen area with its residual haze, but sweeps over the stove and thereby additionally haze up into the suction surface of the hood promotes.
  • An essential advantage of the invention is seen in particular in the fact that the amount of air to be conveyed by the blower is circulated only within the area of the hood-vapor source, so that apart from the much smaller amount of air that can be circulated, which can be achieved thereby, an extraordinarily short path of the air to be circulated is achieved, whereby a precisely defined and particularly effective recirculation takes place.
  • the dynamic upstream is formed between two free jets which are blown vertically onto a flat surface (literature reference H. Hertel "Wall currents and upstream from the deflection of free jet groups" Progress Reports VDI-Zeitschrift, Series 12, No. 11, July 1966), see Figure 6.
  • the inflow to a suction surface takes place from the entire surrounding space.
  • the inflow velocity u S (x) decreases rapidly with the distance x (FIG. 7).
  • the extractor hood 2 is arranged at a normal working distance above a cooker 1 or a hotplate or a vapor source.
  • the suction flow 10 of the suction chamber 4 of the hood 2 and the blower 5 is fed via a filter 3.
  • the Blower conveys the filtered air into the pressure chamber 6. From the pressure chamber 6 of the hood 2, the air at the lower outer peripheral edge of the hood is blown down against the cooker 1 through a front blow-out slot 7 and two side blow-out slots 8.
  • the area of the blow-out slots 8 is in a special embodiment of the invention about 1/10 of the suction surface of the filter 3.
  • the inclination of the blow-out slots 8 is selected so that the blow-out jet 11, which spreads according to the free jet theory, when it hits the work surface of the kitchen range forms a storage line 12 which surrounds the hob area.
  • the upflow 13 is formed, which considerably supports the suction effect of the blower.
  • the blow-out mass flow is divided into a portion I, which is fed back to the hood in the upstream flow, and into the portion II, which gets into the work area, but which does not leave the range of the cooker or the haze source due to the suction effect of the fan and is continuously added to the upstream in recirculation mode.
  • Fig. 3 shows an embodiment of the invention, in which a hood 15 which can be pulled out forwards is arranged on the hood 14.
  • a blow-out slot 16 is provided, which directs the front blow-out stream 17 in the area of the screen 15 to the underside of the screen.
  • a wall jet 18 is formed in which the exhaust air flows along the underside of the screen up to the front edge of the screen and on the underside and leaves the screen at the front edge as a free jet down to the stove. This is preferably done in the manner shown in FIG. 4.
  • the air flow 20 flowing out of the blower 19 passes through the air duct 21 down to a deflecting and baffle surface 22 which defines the air flow 20 deflected and directed as a wall jet 23 through the blow-out slot 16 against the underside of the screen 15 and along its surface up to the detaching edge 24 and then downwards as a free jet 17 against the cooker 1.
