  • the inventive construction of the hood allows a simple and reliable removal of the filter element from the hood.
  • the filter can be particularly simple.
  • no actuator, such as a sliding or pivoting handle on the filter element is necessary.
  • the user of the cooker hood for removing the filter element from the hood only need to cancel the connection that exists from the filter element to the screen via the pivot bearing. This can be done by simply levering.
  • the filter is held on the screen in addition to the locking means by the pivotal bearing, uncontrolled dropping can be prevented even after releasing the detent.
  • the release device is actuated by moving at least part of the umbrella.
  • the part of the screen which is moved to operate the release device may be a body part of the umbrella or a means arranged in the umbrella.
  • the release device is triggered by movement of a portion of the screen, the release of the filter element is further simplified.
  • the part of the screen which has to be moved to actuate the release device is arranged on the front side of the screen or at least forms part of the front side of the screen.
  • the screen faces the user of the hood at least with its front side and can therefore be easily reached by the user.
  • the filter element which is usually provided in the bottom of the screen, the user can easily access the front of the screen and thus initiate the filter change operation or the filter removal process.

  • the guide can serve in different ways. On the one hand, it is possible that the guide itself represents the release device. In this case, the filter element is held in addition to the pivot bearing by resting on a part of the rail in the installed position. By moving the pull-out drawer in the guide, this seating can be canceled and the filter element is pivoted downwards due to gravity.
  • the guide serves as a release device and at the same time as a locking means. The different functions of the support are in this case only due to the different relative positions of the drawer and thus the filter element in the drawer to the guide conditionally.

As a result, the filter element or are pivoted in the Grundköper when pulling out the drawer in the pull-out position in a removal position. Thus, when pulling out the drawer in the pull-out position at the same time or the filter elements in the base body and the or the filter element in the drawer are brought into the removal position.
  • the operating position of the drawer is the position of the drawer with respect to the main body of the screen is called, in which the hood is operated. In this operating position, the drawer can be completely absorbed in the body or pulled out by a certain amount forward from the body.
  • the pull-out position is offset from this operating position.
  • the pull-out screen is preferably pulled further out of the base body in the pull-out position than in the operating position.
  • the removal of the filter is particularly simple in this embodiment, since the user in the simplest case, only the drawer extract relative to the operating position has to pull forward and then the filter element or by loosening the connection, which consists of the pivot bearing, can solve.
