  • the dimension in the direction between the front and the back is called the depth.
  • the vertical dimension to this is called the width.
  • the vertical dimension is called height.
  • an extractor hood device is, in particular, a bowl ventilation, which can also be referred to as a table fan.
  • the extractor device has a suction opening in its upper side.
  • the suction opening is the opening through which air can be sucked into the extractor device.
  • the suction opening can, for example, be provided in an extractor housing of the extractor device, in which the fan of the extractor device, which is also referred to as a fan, can be provided.
  • the suction opening can also be formed by the upper side of a filter unit, in which at least one filter element is provided and that with the fan the extractor device is connected via an air line.
  • the suction opening is preferably located in the plane of the cooktop or cooktops to which the cooktop extractor device is adjacent.

  • An outlet opening is designated as provided in the lower region of the housing of the extractor hood device, which is provided either in the bottom or at the lower end of the housing of the extractor hood device, for example the filter unit or a guide housing.
  • the outlet opening can also be provided at a short distance from the bottom or lower end of the housing of the extractor device.
  • the extractor device has a collecting device.
  • a plurality of collecting devices can also be provided, in particular if the extractor device has several outlet openings.
  • the collecting device is detachably connected to the outlet opening.
  • the collecting device can be connected to the outlet opening via a screw connection or a snap connection.
  • the collecting device has a collecting container.
  • the area of the collecting device in which media, in particular liquids and other impurities, can be received is referred to as a collecting container.
  • the collecting container is a closed space which has only one inlet opening.
  • the material from of which the collecting container is formed that is to say that delimits the interior of the collecting container, is preferably a waterproof material and can be plastic, for example.
  • the collecting container is compressible according to the invention.
  • a collecting container is referred to as compressible, in which the collecting container and thus the interior of the collecting container can be minimized without being destroyed.
  • the material that delimits the interior of the collecting container is therefore preferably flexible and can be folded or compressed, for example.
  • the collecting container In the non-compressed state, which can also be referred to as the expanded state, the collecting container preferably has a capacity of at least one and preferably at least two liters. In the compressed state, the interior of the collecting container is reduced to a minimum. For this purpose, the collecting container can be folded, rolled up or otherwise compressed, for example.
  • a collecting device which is compressible and which is releasably attached to an outlet opening of the extractor device, which is arranged in the lower region of a housing of the extractor device, or is releasably connected to the latter, a number of advantages can be achieved.
  • a fume extractor device in which the suction opening is formed in the upper side thereof and in which air is thus sucked in downward, contaminants can penetrate during cooking processes. For example, if food is boiled over or spilled on a hob that is adjacent to the suction opening, larger amounts of liquid such as water or foodstuffs such as milk or soup can enter the extractor hood device.
  • Such liquids will run in the extractor device in the lower region of a housing of the extractor device.
  • an outlet opening according to the invention in this area, the liquids can thus be easily and reliably removed from the extractor device.
  • a collecting device with a collecting container is also provided at the outlet opening, the liquids can be reliably collected therein.
  • the collecting device can then either be cleaned or replaced by a new collecting device. Since the collecting container is compressible, the space which is occupied by the collecting container in the compressed state is minimized. Only in the state in If the collecting container is filled with liquid, that is to say in the non-compressed state, this takes up a larger space. Thus there is more installation space in the extractor device in which the further components of the extractor device can be arranged, or the size of the extractor device can be reduced overall.
  • the extractor device has a filter unit with a filter housing and the outlet opening lies in the underside of the filter housing.
  • At least one filter element is preferably arranged in the filter housing, through which contaminants, such as fat and liquid particles, are filtered out of the air stream.
  • the filter element or elements can therefore also be referred to as a grease filter.
  • the filter unit is usually near the suction opening or forms part of it.
  • the embodiment in which the outlet opening lies in the underside also has a further advantage.
  • the underside of the filter housing usually represents the lower limit of the part of the extractor hood device that lies in the area of the hob. Below this part of the extractor hood there is, for example, storage space for pots and pans. In particular school supplies can be arranged. Since the collecting container of the collecting device is compressible, this storage space is fully or largely available in the compressed state of the collecting container. Only when larger quantities of liquid or fat get into the collecting container does the collecting container unfold and protrude into the storage space.
  • the underside of the filter unit is easily accessible to the user. For example, the user can gain access to the collecting device by pulling out the drawer.
  • the collecting container is formed by a bag.
  • the bag can also be referred to as a sack or bag.
  • the collecting container can consist, for example, of a plastic film.
  • the thickness and composition of the plastic film is chosen so that the film is tear-resistant and can carry the weight of a filling volume of at least 2 liters.
  • the advantage of the design of the collecting container as a bag is that a bag can be compressed to a very small size. In addition, this can be produced inexpensively and the collecting device can thus be a disposable product.
  • the collecting container can also be formed, for example, by a bellows which is closed at the bottom.
  • the space occupied by the collecting container in the compressed, that is to say compressed, state is small.
  • the wall thickness of the bellows can be larger compared to the thickness of a plastic film and thus provide a reliable capacity for the collecting container of at least 2 liters.
  • the collecting device has a fastening element for detachable fastening to a counter element at the outlet opening.
  • the fastening element can represent a screw element, for example, and the counter element on the outlet opening can represent a corresponding thread.
  • the fastening element can also be a latching element, for example.
  • the counter element can represent, for example, a latching opening in a flange at the outlet opening.
  • the counter element can also be the area around the outlet opening and a locking element on the fastening element can engage behind the outlet opening.
  • the fastening element and the counter element in the form of a bayonet lock can work together. In any case, however, the fastening element is designed such that it has a passage opening through which liquids can get into the collecting container.
  • the collecting container is at least partially and preferably completely accommodated in the fastening element in the compressed state.
  • the height of the collecting device in the compressed state is limited to the height of the fastening element.
