Definitions

  • the invention relates to an extractor hood device according to the preamble of claim 1.
  • the invention relates to an extractor device with a vapor screen, which is movable relative to a support member between a rear position and a front position.
  • Extractor hoods of this type are known from DE-A-42 43 944 and are used for extracting vapors (fat-containing cooking fumes) over hotplates, in particular a stove. Extractor hoods that convey the extracted vapors back to the kitchen are referred to as recirculation hoods, extractor hoods or food that promote the extracted vapors to the outside atmosphere are referred to as exhaust hoods or food. Exhaust hoods usually do not have a grease filter, while recirculation hoods always contain a grease filter and often also an odor filter.
  • the extractor hood device of the aforementioned DE-A-42 43 944 also has an additional fat filter in addition to the main fat filter, which can be moved from a rear position if required can be pulled out of the extractor device into a front position, so that the additional filter in its rear position does not restrict the freedom of movement and the field of vision of a person to the hotplate.
  • the main grease filter and thus also the extractor hood device can thus be made shorter in size from front to back in order to improve the freedom of movement and the field of vision of an operator.
  • So-called flat screen hoods are extractor hoods that are integrated in a wall cabinet and have a vapor screen that can be pulled out of the wall cabinet if required.
  • the flat screen hood has only been pulled out a full steam function.
  • the vapor screen is retracted, however, the flat screen hood disappears completely in the wall cabinet and there is maximum headroom for an operator when working on a hotplate located under the flat screen hood. If the vapor screen is pulled out in order to direct vapors (fat-containing cooking vapor) over a hotplate into the flat screen hood, it is perceived as a disturbing device because it restricts the headroom and the field of vision of an operator to the hotplate and to pots placed on it. Furthermore, it can easily happen that the person hits his head on the vapor screen.
  • the invention is intended to achieve the object of preventing an unintentional bumping of the head onto the vapor screen of the extractor hood device and, at the same time, of improving the head space and the field of vision of a person during the cooking operation on the hotplate and in pots and pans located thereon. This is to achieve greater operational safety against accidents during cooking.
  • an extractor device is characterized in that an electrical drive device for moving the vapor screen and a proximity sensor device are provided, that the proximity sensor device within a predetermined minimum distance from the vapor screen within a defined safety range on the
  • the presence of the person reacts and controls the electric drive device in order to avoid the collision with him, in particular with his head, by moving the vapor screen backwards from the front position to the rear position.
  • proximity sensors are attached to the vapor screen of the extractor hood device, which have an electric drive device for retracting and extending the wax screen, for.
  • B. ultrasonic sensors
  • Infrared sensors or light barriers The sensors are placed in such a way that an approach of a person, in particular the head of a person, from a predetermined distance, for example about 7 cm, is recognized at the front and side of the vapor screen. This predetermined distance defines a safety area around the vapor screen, within which the approach of a person, in particular of his head, is recognized by the sensors.
  • the mode of operation and mode of operation of the invention can be designed similarly to that of "park distance control devices" of passenger cars. The difference to the invention, however, is that a distance signal is generated in a passenger car, while in the invention the vapor screen is generated by an electromotive
  • the device is retracted when a person approaches the vapor screen closer than the predetermined minimum distance.
  • the drive device can be used to move the vapor screen in both directions or only in the direction from front to back, i. H. be designed only for evasive movements to avoid a collision.
  • the vapor screen can be moved back from the front position to the rear position by the drive device when the minimum distance between people is undershot or can only be retracted to such an extent that the safety distance from the operator is maintained. Further can be provided that the drive device moves the vapor screen forward again to the starting position when the operator moves away.
  • the drive device moves the vapor screen forward again to the starting position when the operator moves away.
  • Fig. 1 shows schematically a vertical section through a
  • Extractor hood device of the invention seen along the plane l-l in the direction of the arrows of FIG. 2,
  • FIG. 1 schematically shows a front view of the extractor hood of FIG. 1,
  • Fig. 4 schematically shows a vertical section similar to Fig. 1, but of a further embodiment according to the invention.
  • the extractor device according to the invention shown in FIG. 1 in the form of an extractor hood contains in a housing 2 a suction fan 4 for sucking in fumes 6 (cooking vapor containing fat) through a main fat filter 8 on a rear flow path 10 and successively only through an additional fat filter 12 and then through an overlying region of the main grease filter 8 along a front flow path 14 when the auxiliary grease filter 12 is in the front position shown in FIG. 1.
  • the air 16 cleaned by the fat filters 8 and 12 is conveyed back by the suction fan 4 through an outlet 18 into the space from which the vapor 6 was sucked in.
  • the outlet 18 can also be connected to the outside mosphere to be connected to promote the air 16 into the outside atmosphere.
  • Grease filters 8 and 12 are often not used for such an exhaust air operation into the outside atmosphere.
  • the main grease filter 8 can be followed in a known manner by an odor filter 20 in the two flow paths 10 and 14 in order to remove kitchen odors from the vaping 6.
  • Odor filters 20 mostly have activated carbon as the odor-absorbing material, but other materials can also be used.
  • An odor filter 20 is normally not used for exhaust air operation, but only for recirculated air operation if the cleaned air 16 of the vapor 6 is conveyed back into the room from which the vapor 6 is extracted.
  • the additional grease filter 2 is located in a drawer-like vapor shield 22.
  • the vapor shield 22 is provided by an electric drive device 24 between the front position shown in solid lines in FIG. 1 and the rear position shown in dashed lines 22-2 in FIG. 1 Position and preferably also in intermediate positions back and forth movable.
  • the front position is the operating position for suction of vapors 6 via cooking vessels 26 on a hotplate 28, for. B. a hob or a hob with cooking zones.
  • the rear position in dashed lines 22-2 is the inoperative position, in which the vapor screen 22 is more or less completely retracted into the front 30 of the housing 2 and gives an operator a great deal of freedom of movement and a large viewing area into the cooking vessels 26 and the hotplate 28 ,
  • the automatic retraction of the vapor screen 22 automatically gives the person more freedom of head movement and a larger field of view of the hotplate.
  • the proximity sensors 34 preferably operate without contact and are preferably ultrasonic sensors or infrared sensors or light sensors of a light barrier.
  • the proximity sensor device 32 also contains an electrical or electronic control device for controlling the electrical drive device 24.
  • the electric drive device 24 can be a linear drive with a telescope positioner 40 for positioning the vapor shield 22 or an electric motor, for example an electric stepper motor.
  • the electric motor can be drivingly connected to the vapor shield 22 for forward and backward movement thereof by known means, for example via an endless drive element such as a drive belt or a drive chain, or via a pinion which engages in a toothed rack which engages on the Vapor screen 22 is provided.
  • the invention can be implemented in various ways:
  • the drive device 24 can be designed to move the vapor screen 22 in both directions and thus to move to the rear position 22-2 and to move to the front position 22. According to another embodiment, the drive device 24 can be configured to move the vapor screen 22 only in Direction from the front position to the rear position 22-2, but not for moving in the opposite direction, in which it can be moved manually. Furthermore, it can be provided for both of the aforementioned embodiments that the movement speed of the vapor shield generated by the drive device 24 is dependent on the speed at which a person approaches the vapor shield 22. In all embodiments, the approximation Sensor device 32 designed so that it controls the drive device 24 according to the aforementioned functions.
  • the proximity sensor device 32 and the drive device 24 are designed in such a way that they later move the vaporizer 22 back to its starting position after an evasive movement backwards, if after a dodging movement the person has distanced himself again from the vaporizer 22 and is outside the security area 38.
  • the vapor screen can be adjusted manually and / or by electric motor not only in the rear position and / or in the front position, but also in at least one defined intermediate position or preferably in any intermediate position.
  • the proximity control device 32 is preferably designed such that it only reacts to the approach of a larger part of the body, in particular the head of a person, but not to smaller parts of the body, e.g. B. a hand, or that it does not respond to proximity to a person in a predetermined area of the vapor screen 22, in which it is manually detectable for its positioning or manually operated controls.
  • electrical lighting 44 can be integrated into the underside of the extractor hood device, which illuminates downwards onto the hotplate.
