Definitions

  • the present invention relates to an extractor device with a connection device and a method for connecting an extractor device to an air duct.
  • the air In the event that the extractor device is operated as an exhaust device, that is, the air is released into the environment, for example through a wall box, the air must also be conducted from the extractor device to the wall box. Even in a recirculation mode, in which the air is released into the room in which the extractor device is operated, the air is preferably passed out of the kitchen furniture to an air duct.
  • the air duct for guiding the air into the surroundings or into the room is usually arranged behind the rear wall of the furniture or is partially formed by the rear wall of the kitchen furniture.
  • the distance between the hob and thus the extractor device and the air duct usually provided behind the kitchen furniture varies.
  • the connection of the extractor device to the air duct is difficult due to the installation position of the extractor device and the limited installation space behind the extractor device.
  • an extractor device with a connection device for connecting an air duct, the extractor device being designed for installation in kitchen furniture and comprising a device housing which has at least one air outlet opening in a side wall.
  • the extractor device is characterized in that the connection device comprises at least one pull-out element which is at least partially movable relative to the position of the air outlet opening.
  • the extractor device is preferably an extractor device integrated into a hob.
  • the extractor device has a device housing.
  • the fan of the extractor hood device can be arranged in the device housing.
  • the device housing has at least one air outlet opening.
  • the air outlet opening is arranged in a side wall of the device housing.
  • the air outlet opening is preferably arranged in the rear wall of the appliance housing, which, after the installation of the extractor device, faces the rear wall of the kitchen furniture in which the extractor device is introduced.
  • the modules of the hob are preferably also accommodated in the device housing.
  • the air outlet opening is used to let out or blow out purified air from the extractor device.
  • the piece of furniture in which the extractor device is installed is preferably a kitchen base unit that is placed against a room wall, or a kitchen island, the rear wall of which is covered by a rear cover.
  • the air duct to which the extractor device is connected can be formed by the space between the rear wall of the kitchen furniture and the wall of the room on which it rests, or a rear cover. In these cases, the back wall of the kitchen unit forms part of the air duct. However, it is also within the scope of the invention that the air duct is a pipe that connects to the rear wall of the kitchen furniture. In this case too, however, at least the air inlet opening of the air duct is provided in the rear wall of the kitchen furniture.
  • the extractor device comprises a connection device.
  • the connection device is used to connect the extractor device to the air duct and in particular to connect an air outlet opening of the extractor device to an air inlet opening of the air duct.

  • the distance between the air outlet opening of the extractor device and the air duct, in particular the air inlet opening of the air duct can be bridged flexibly. Since the distance can also be covered or bridged by the pull-out element, it is not necessary to subsequently introduce an intermediate element between the air outlet opening and the air duct after the installation of the extractor device. This facilitates the assembly of the extractor device and in particular the connection of the extractor device to the air duct.

  • sealing elements, in particular sealing rings 7, are provided on the fastening frame 21 on the rear or front side of the flange 2101 and on the adapter 23 or the latching frame 2010.
  • connection device 2 comprises 2 in addition to the elements of the embodiment according to Figure 8 an insert element 22.
  • the other parts of the connection device 2 according to Figure 9 correspond to those of Figure 8 and are therefore not explained again.
  • the insert element 22 is preferably made of plastic.
  • the insert element 22 has the shape of a half-frame which is open at the bottom.
  • the aim of the insert element 22 is to bring the fastening frame 21 and thus the flexible channel element 201 into position and to stop the translation in the longitudinal direction of the flexible channel element 201.
  • the device housing 10 of the extractor device 1 can now be introduced into the kitchen furniture 3.
  • the user In order to connect the fastening frame 21 and thus the flexible duct element 201 to the rear wall 30, the user must insert the fastening frame 21 behind the insert element 22, push it from below behind the half-frame in the embodiment shown, and then screw / glue it to the rear wall.
  • the flexible duct element 201 can then be fastened to the air outlet opening 100 via the latching frame 2010 and the adapter 23, in particular adapter frame 230, and thus connected to the extractor device 1.
  • connection device 2 differs from that in Figure 8 embodiment shown by the different design of the locking frame 2010 and the adapter 23.
  • the other components are the same and are therefore not described again.
  • the adapter 23 represents an adapter clasp 231.
  • This has the shape of a half-frame and is open at the bottom.
  • This adapter clasp has a width which is greater than the width of the latching frame 2010, which is provided at the free end of the flexible channel element 201.
  • the latching frame 2010 has a sealing element 7 in the upper area. In the lower area, the latching frame 2010 represents a closed profile.

  • the locking frame 2010 can be pushed from bottom to top into the protrusion of the adapter clip 231 until the locking elements 60 of the adapter clip 231 and the locking frame 2010 lock together.
  • the invention has essentially been described with reference to an extractor hood device which is integrated with a cooking module.
  • the extractor device is integrated in the kitchen furniture separately from the cooking module.
  • the extractor device sucks cooking vapors and fat downwards and can also be referred to as a downdraft extractor.
  • connection device can prevent air from being blown out of the extractor device into the kitchen furniture. Furthermore, a reliable connection of the extractor hood device to the air duct is made possible for different types, in particular different dimensions, of kitchen furniture.
  • the invention allows the extractor device to be connected quickly and easily to an air duct. Finally, with the connection device, good airtightness can be ensured in a simple manner, in particular at the transitions from the device housing to the connection device and from the connection device to the air duct.
