Definitions

  • the invention relates to an extractor hood with pull-out screen.
  • a movable against the extractor hood of the extractor hood extract screen is provided.
  • the pull-out screen which is also referred to below as a drawer, and in particular by a forward pulling out of the pull-out screen, the area can be sucked through the fumes and vapors in the extractor housing, can be increased.
  • a pull-out screen is in the form of a body. This can be moved at Auszugsessen relative to the fireplace as a vapor extraction housing and in particular moved forward. Again, the suction is increased.
  • Extensible screens in extractor hoods are generally guided in telescopic rails or roller rails. In order to move the extract screen relative to the extractor housing in the rails, it is known that this is moved manually.
  • an extractor hood is described in which the pull-out screen is moved over a spiral spring arranged behind the pull-out screen.
  • the handling for the user can indeed be improved compared to a purely manual operation.
  • the actuation or movement forces which the user has to apply in particular in the end region before the retraction of the extension screen must be high.
  • various motorized displacement systems which are also referred to as opening systems known.
  • the pull-out screen is brought into the operating position by motor, that is, extended or retracted.
  • a disadvantage of the manually operated systems is that the user must move the sometimes heavy pullout screen by hand and thus has to apply high forces.
  • motor-driven systems have the disadvantage that they have a complex structure, must be subject to regular maintenance and are expensive to produce and to operate.
  • Object of the present invention is therefore to provide a cooker hood on which the pull-out screen can be moved easily and the construction of the hood is still easy.
  • the invention is based on the finding that this object can be achieved by using a suitable spring element to support the movement of the pull-out screen.
  • an extractor hood which has a fume hood housing and a pull-out screen which can be displaced with respect to the fume hood housing.
  • the extractor hood is characterized in that the extractor hood has at least one scroll spring for supporting the displacement of the extension screen whose spring force points in the direction of the roller of the scroll spring.
  • the extractor housing designates the housing in which preferably the fan or the fan of the extractor hood is received.
  • the pull-out screen which is also referred to as a pull-out drawer or drawer, preferably has at least one inlet opening for the intake of fumes and vapors.
  • at least one filter element is preferably provided in the extract screen.
  • the extract screen is preferably connected to the extractor housing so that in the extended state of the Ausziehless air flowing to the or in the Ausziehtransport, can be directed into the interior of the extractor housing.
  • the pull-out screen is horizontally displaceable.
  • the pull-out screen is displaced in a direction deviating from the horizontal direction.
  • the opposite to the extractor housing extended or extended state of the pull-out screen is also referred to below as the operating position.
  • the retracted on the or in the extractor housing or retracted state of the pull-out screen is also referred to below as the rest position.
  • the movement between the resting position and the Operating position and vice versa is referred to as moving or method.
  • the distance by which the pull-out screen is displaced is referred to as travel or displacement.
  • the hood on at least one scroll spring to support the displacement of the extension screen, the spring force points in the direction of the roller of the scroll spring.
  • a spring element or a spring is referred to, which is a special form of a coil spring and has no winding spacing. In the relaxed state, therefore, the turns of the spring element are directly adjacent to each other.
  • One of the ends which is also referred to below as a free end, preferably extends tangentially to the roller in which the turns of the spring element are rolled up.
  • the spring force of the scroll spring keeps the spring over its entire length, minus the free end in the rolled-up state, that is directed from the free end to the roll of the scroll spring.
  • at least one scroll spring is provided in the extractor hood. It is also provided in the scope of the invention, a plurality of rolling springs. For the sake of clarity, reference will be made below to a scroll spring. However, the statements apply - as far as applicable - also respectively for several roller springs, without this being mentioned.
  • the support of the displacement of the extension screen which is effected by the scroll spring, is preferably carried out in a direction of displacement by the spring force of the scroll spring. In the opposite direction of displacement, the support of the displacement takes place by the scroll spring is at least partially used as a guide for the pull-out screen and in particular tilting of the pull-out screen is prevented.
  • further guide elements such as rails or rollers, may be provided in the extractor hood according to the invention, but are not absolutely necessary.
  • the scroll spring may be mounted on the axle of the roller. According to the invention, it is also possible to provide no fixed bearing of the scroll spring on the axis, but to arrange the roller with its outer turn on a component, so that when rolling the roller, the outer turn is pressed against the component.
  • the component may be, for example, a web or wedge.
  • roller springs can have a constant spring characteristic.
  • a constant operating force over the entire length of the displacement can be achieved.
  • the motive force, which is necessary to move the pull-out screen in the opposite direction is constant over the entire displacement path.
  • a scroll spring in the relaxed state on a small size, whereby only a small space in the hood for the scroll spring must be provided.
  • a scroll spring is robust, so that extension screens can be moved with great weight by means of the scroll spring or the roller springs.
  • the scroll spring is oriented so that the axis of the roller of the scroll spring is perpendicular to the surface of the pull-out screen.
  • the scroll spring in the extended state of the Ausziehnes ie the operating position of the Auszugstubs, relaxed.
  • the scroll spring is preferably taut. This ensures that the extension of the extension screen due to the scroll spring can be done completely automatically with sufficient spring force. The user therefore does not have to apply additional force for this movement.
  • the user only has to counteract the spring force. Since these can be constant over a spring on the spring travel, the applied by the user opposite force is low and especially in the final phase or initial phase of insertion no higher or only slightly higher forces must be applied.
  • the extractor hood on two roller springs which are arranged on the longitudinal edges of the extension screen.
  • Longitudinal edges here are understood to be the edges which lie in the direction of displacement of the extension screen.
