Definitions

  • the present invention relates to an extractor hood according to the preamble of claim 1.
  • Extractor hoods are usually designed for filtering Kochwrasen in the exhaust air operation and / or recirculation mode.
  • the vapor is sucked at the point of origin of a fan and passed through an exhaust duct and / or a wall box either directly into the open or in an air chimney.
  • a working in exhaust air extractor hood is for example from the document DE 94 16 271 U1 known.
  • the housing of this cooker hood is very compact. It surrounds encapsulating a radial fan, which is arranged to generate negative pressure in the suction chamber.
  • the air outlet openings of the radial fan are directed tangentially upwards and connected to an exhaust air duct or an exhaust air chimney.
  • a disadvantage of the exhaust air operation are its complex structure, the need for an exhaust air connection and the lower energy efficiency compared to recirculation mode.
  • recirculation mode In recirculation mode, the vapor is circulated for filtering within a room.
  • the recirculation mode is very energy efficient, especially at low outdoor temperatures, because in the recirculation circuit, the room air is maintained during the entire ventilation process.
  • a disadvantage of the recirculation mode is the lower ventilation performance compared to the exhaust air mode.
  • extractor hoods operating in the exhaust air or recirculating air mode are known.
  • the suction fan is mounted in the vertical swivel. By pivoting the suction fan, the air outlet of the suction fan is connected to an exhaust pipe or separated from it. The escaping air is blown at any vertical angle upwards, forwards, downwards or backwards.
  • the extractor hood can not be arranged at any height above a cooktop or do not protrude arbitrarily deep to the operating side of the extractor hood.
  • An air outlet pointing downwards or towards the hob is unfavorable, because the escaping air blows away the steam from the hob and thus prevents the vapor from being sucked into the extractor hood for filtering purposes.
  • An upward air outlet is unfavorable, because it can clog when not in operation by dust deposits. Also, upwardly directed exhaust openings are difficult to reach, which is why their cleaning is complex. Forward or to the operating side of the hood directed towards exhaust openings are unfavorable because they cause an unpleasant air movement in the direction of the user of the hood.
  • the present invention has the object, a hood of the type mentioned in such a way that the housing of the hood is designed to be as compact as possible, in particular that the quotient of extractor and Housing size is increased.
  • the fan or the fan should be arranged with as little space in the housing.
  • the present invention is based on the housing having a substantially cylindrical profile.
  • This form of housing is the most compact envelope of the functionally substantially circular or circular fan.
  • the inventive cylindrical housing shape minimizes the aerodynamically dead areas in the interior of the housing.
  • the cylindrical housing is advantageously arranged lying.
  • a cylinder arranged horizontally above a cooking point has a larger surface facing the cooking surface, and can suck in significantly more of the cooking point outgoing vapor or vapor into the suction chamber as a vertically arranged cylinder.
  • the vapor is sucked in the region of the lower half of the cylinder and laterally filtered, preferably in the horizontal direction, filtered.
  • This has the advantage that the extractor hood can be arranged at any vertical distance above a hob. Also, due to the unobstructed and non-obstructive lateral air outlet, a particularly powerful fan can be used.
  • the housing For lateral blowing out of the extractor hood exiting air or the filtered Wrasens, the housing at least one of its two substantially mutually parallel side surfaces at least one exhaust opening.
  • Vertical purging of the filtered vapor is not only advantageous because the air outlet obstructs neither the user of the hood nor the suction of the vapors, but also because in this way the suction of the hood is even supported.
  • the air emerging from the extractor hood in the horizontal direction forms an air barrier which prevents the vapor from escaping past the extractor hood and escapes unfiltered to the top.
  • At least one grease filter and at least one odor filter are advantageously arranged in the housing.
  • the odor filter may be, for example, at least one activated carbon filter or at least one plasma filter. So that the odor filter and / or the grease filter can be arranged as compact as possible in the housing, it advantageously has a substantially cylindrical shape.
  • the housing of the extractor hood has at least one suction opening.
  • the suction advantageously extends substantially over the entire length of the mantle or cylindrical surface of the housing.
  • the region of the housing which has the suction opening in the position of use of the extractor hood is advantageously oriented downwards, in particular facing the cooking position.
  • FIGS. 1 and 2 illustrated first embodiment of an extractor hood 100 according to the present invention as well as on in FIG. 3 illustrated second embodiment of an extractor hood 102 according to the present invention.
  • a cooker hood 100 namely a Um poverty-Wandesse shown in a cylinder shape.
  • This Um poverty Wandesse 100 is solitary mounted above a hob 200.
  • the extractor hood according to the present invention as a circulating air island 102 (see. FIG. 3 ), ie over one in FIG. 3 Not shown cooking island arranged to be.
  • the housing 10 surrounds the Um Kunststoff Wandesse 100 with its substantially cylindrical profile encapsulating at least one suction chamber in which at least one fan 40 is arranged to generate negative pressure.
  • the cylindrical profile of the housing 10 is arranged completely in space.
  • the housing 10 thus has a complete cylindrical profile and, for example, is not a truncated cylinder.
  • the circulating air wall 100 has at least one suction opening 32 extending substantially over the entire length L of the jacket or cylindrical surface 30 of the housing 10.
  • This suction opening (s) can be formed for example by at least one perforated plate or at least one fin arrangement.
  • the region 32 of the jacket or cylindrical surface 30 of the circulating air wall 100 facing the cooking point 200 can essentially be formed from at least one perforated plate or from at least one laminar arrangement.
  • At least one working light 50 is advantageously arranged in the region 200 facing the hotplate 200.
  • This work light 50 extends for uniform illumination of the working surface 200 substantially over the entire length (L) of the shell or cylindrical surface (30) and is arranged centrally above the work surface.
  • the suction opening (s) having region 32 of the housing may be surrounded by a frame member 36.
  • the cleaning of the suction opening (s) having region 32 is facilitated if this region 32 is removable from the housing 10 and can be inserted into the housing 10.
  • this region 32 can consist of a plurality of perforated metal cassette cassettes that can be cleaned in a dishwasher.
  • a high-tech filtration such as at least one plasma and / or activated carbon filter arranged.
  • the housing 10 at at least one of its two side surfaces 20, 22 exhaust openings.
  • the filtered vapor is blown out through the exhaust opening (s) in a substantially horizontal direction.
  • the vapor is sucked in the lower half of the cylinder 32 and laterally filtered horizontally blown (in FIG. 1 block arrows shown on the side surfaces 20, 22 indicate the direction of discharge).
  • control and / or display element 34 is advantageously arranged above the suction opening (s) and as a control element with touch input, as a so-called touch zone formed.
  • FIGS. 1 to 3 shown extractor hoods 100, 102 differ from known from the prior art convection hoods in particular in that the housing 10 has a cylindrical profile, wherein the fan 40 is disposed within the housing 10.
  • Another advantageous delimitation criterion compared with the prior art is that the vapor is sucked on the underside 32 of the housing 10, preferably along the cylinder 30, filtered in the housing 10 and blown out to the cylinder end faces 20, 22. In this way, a compact, high performance recirculating air icing 100 is provided.
