Abstract

To configure existing drawers as evacuable drawers of a vacuum drawer device, a cover for installation in the drawer body can be used. The cover evacuates at the drawer interior with an evacuation system, so that the interior is evacuated when the drawer is closed and ventilated before the drawer is opened. The cover is airtight, is profiled in such that evacuation with a controller, a pump and a valve are fixedly integrated in at least one recess in the cover and the cover has at least one air channel leading into the inside of the cover or, respectively, into the at least one recess, with the air channel operatively connected to the evacuation system such that when the cover is placed onto the drawer, air from the interior can be pumped out of the interior, the inside of the cover interior or, respectively, the at least one recess through the air duct.
