Definitions

• the present invention relates to a refrigeration appliance, in particular a household refrigeration appliance, which is particularly suitable for the storage of desiccated refrigerated goods.
• Fresh foods such as fruits, vegetables, salads or fresh herbs will continue to release moisture to their surroundings until they are balanced between them and the surrounding air.
• Moisture that releases such food to the air in a storage chamber of a refrigerator condenses usually after a short time on a storage chamber cooling evaporator, so that the humidity never reaches a saturation state.
• foods constantly lose moisture, dry quickly and become unsightly.
• WO 2013 186 128 A1 discloses a household refrigerating appliance in which a lid is suspended from a shelf dividing the storage space, which lid rests tightly on an extract box in the pushed-in position. Through closable openings of the lid, a user can adjust the amount of air exchange between the interior of the drawer and the surrounding storage space.
• Object of the present invention is to provide such a structure.
• the storage space is divided by a shelf in an upper and a lower compartment and in the lower compartment a drawer is received, in one in the lower Tray inserted stop position of the drawer a front wall of the drawer at a front edge of the Tray abuts, the shelf has a passage, and a closure element between a passage obstructing position and a passage on at least a portion of its cross-section releasing position is movable.
• the front wall of the drawer in the stop position at the front edge of the shelf or the stop position is even defined by the concern of the front wall at the edge of the shelf, an air exchange between the interior of the drawer and its surroundings in the stop position at least along the front wall locked out.
• Such a seal may be sufficient on its own if, in the stop position, the front wall as a whole closes the lower compartment receiving the pull-out box as a whole; if this is not the case, other solutions, which will be described in more detail below, can be provided to prevent the air exchange along the side walls of the pull-out box.
• the attachment of the passage in the shelf makes a lid for the drawer as a separate component from the shelf redundant. In order to be easily accessible to a user, the passage is preferably arranged adjacent to the front edge of the shelf.
• the shelf in a conventional manner comprises a frame and a framed by the frame plate, the passage is preferably recessed from the frame.
• Such a slider may be composed of two elements, one of which forms an upper side wall and the other a lower side wall of a groove, in which engages the plate or a web of the frame to the adjustment movement of the slider between the passage blocking position and to lead the releasing position.
• the frame may in particular have a web provided with openings, the openings of which are exposed in the open position of the cross section of the Transit form, and which is opposite to an edge of the plate, so that the slide between the passage of the web obstructing position and a releasing position is displaceable, in which parts of the slide on the plate.
• top wall elements may be detachably mounted on side walls of the pull-out box.
• the side wall elements are connected to each other via a rear wall element.
• the rear wall element can serve, on the one hand, to fix the side wall elements in relation to one another, in order to ensure that in the inserted stop position, both simultaneously seal at the upper edges of the side walls; It can also perform a sealing function itself between a rear wall of the pull-out box and the shelf.
• the upper edges of the side walls of the drawer and optionally also the rear wall sealing surfaces which rest in the retracted stop position on the suspended side and / or rear wall elements are stiffened by webs angled along their upper edges, in particular the upper sides of these webs can serve as sealing surfaces.
• the side wall elements can be vertically suspended playful from the shelf to compensate for any manufacturing tolerances can.
• the side wall elements can then each have at an upper edge a flange facing the shelf, which, by forming a narrow gap together with the shelf, the air exchange between the interior of the Although pull-out box and the surrounding storage space can not completely prevent but at least severely restrict.
• the drawer can have a height profiled bottom plate, at the lowest points of condensation can collect, while intermediate higher places protect the refrigerated goods and keep away from condensation.
• Locally deepest points of the bottom plate are preferably adjacent to the walls of the pull-out box, first, because such places for the refrigerated goods are the harder to reach, the closer they are to the walls, on the other hand, because the condensation is predominantly on the walls of the Pull-out box forms.
