Definitions

  • the present invention describes a multi-layer sandwich-constructed lid for placement on a drawer of a vacuum drawer device, which lid enables evacuation of a drawer interior after sealing to the drawer, wherein the lid has at least one outer airtight cover layer and a core layer, wherein recesses are formed in the core layer and partially in one of the at least one outer cover layer, in which recesses an evacuation channel, a pump and at least one sensor are arranged.
  • Refrigerators for storing food have several disadvantages, as they constantly require a lot of electrical energy to maintain constant, massive cooling.
  • the internal climate of refrigerators has received little attention to date.
  • the Hygiene Council which conducted an international study called the Hygiene Report 2010, refrigerators contain around 1,140,000 germs per square centimeter, which is more contaminated than a toilet, which has around 100 germs per square centimeter. This report received widespread media coverage in 2010, but other than recommendations to clean refrigerators more frequently, no noticeable improvements have been made so far.
  • Vacuum drawer device For the first time in the DE202017006169 generally discloses a vacuum drawer device with a drawer and a lid, wherein a vacuum can be generated in the interior of the drawer by means of a pump.
  • Vacuum drawer device comprises a drawer with walls and a drawer interior, wherein the drawer is operatively connectable to a lid and is mounted within a drawer body for linear movement. Further details about the drawer, the lid, possibly lifting means and evacuation means are in the DE202017006169 but largely left open.
  • the closest state of the art is the WO2019/141574 of the applicant.
  • Food that does not necessarily require refrigeration can be stored at room temperature in a vacuum drawer device, thereby avoiding increased energy consumption for cooling.
  • the drawer interior is evacuated to a slight negative pressure, which is generated and maintained in a controlled manner. This makes it easier to keep food edible or enjoyable for longer.
  • Storage in a drawer body with a vacuum drawer device requires less energy than a refrigerator, as the oxygen removal from the interior is completed after a few minutes and almost no further electricity is required thereafter.
  • a vacuum drawer device can be implemented without harmful materials such as refrigerants or thermal insulation.
  • the consumption of plastic bags in the conventional vacuum sealing using vacuum sealers can be significantly reduced, yet food can still be stored for longer periods without any problems.
  • the drawer body forms the outer shell, within which the lid and drawer are movably and securely mounted. Electrically operated lifting and evacuation devices are located in the lid or drawer, allowing controlled evacuation when the lid is placed on the drawer. Air can be pumped out of the drawer interior through an air duct. With the installation of sensors, the evacuation can be automated, and ventilation before the drawer is opened can also be detected and automatically initiated by the control system.
  • the lid is designed to be as compact as possible, with multiple layers, and can also be easily mounted on existing drawers. To keep the height of the lid low, the lifting and evacuation devices are integrated into the lid as much as possible. In practice, however, the lid is still relatively heavy and bulky, and constant operation of the lid, i.e., with opposing lifting movements, can lead to malfunctions.
  • the lid 2 which is movable within the drawer body 9 and is designed to be airtight, serves to evacuate the drawer interior R.
  • the lid 2 is mounted so that it can be lowered onto the drawer 3 in a lifting direction H perpendicular to the pushing direction S.
  • the lid 2 is attached to the drawer body 9 with mounting brackets 19, so that a relative movement of the lid 2 to the drawer 3 is possible.
  • Lifting means 7 are arranged on or in the lid 2 within the drawer body 9, which keep the lid 2 movable within the drawer body 9 in the lifting direction H.
  • the design of the lifting means 7 can be carried out in different ways, which will not be discussed further here.
  • FIG. 2 The airtight, multi-layered lid 2 is shown resting on the drawer 3 or sealing fittings 15.
  • the surrounding drawer body 9 is omitted for simplicity, and the drawer 3 is shown in section with a front panel 17 and a handle 12.
  • the lid 2 rests on the container interior R or the containers 14, hermetically sealing them.
  • At least one evacuation channel should be arranged within the cover 2 in recesses A.
  • recesses (A) are formed in a core layer (21') and partially in one of the at least one outer cover layers (22") of the cover (2), in which recesses an evacuation channel and/or a dehumidification channel, a pump and/or a fan and at least one sensor are arranged.
  • Automated evacuation by means of a pump can be achieved through the at least one evacuation channel, and automated air exchange by means of a fan 81' of the drawer interior R or the interiors of the containers 14 can be achieved through the at least one air channel.
  • the different paths of the air during evacuation and air exchange are indicated by dashed lines.
  • a power cable 27' is arranged to a connector plug 25', which operates the control unit that controls the lifting means, the evacuation means, the air exchange means, and the sensors.
  • the control unit is also arranged in a recess A in the lid 2, but could also be arranged within the drawer body 9, separate from the lid 2.
  • the cover 2 is manufactured in a sandwich construction, with different materials being combined in different layers to form a cover 2.
  • the cover 2 has two outer airtight cover layers 22', 22" and a core layer 21'.
  • an additional printed circuit board 20' which can also be used instead of one of the outer airtight cover layers 22', 22".
  • the layers 20', 21', 22', 22" are statically bonded together to form a multi-layer cover 2, which is designed to be correspondingly torsionally rigid.
  • the upper cover layer 22' is airtight and can be made of MDF, CFRP, or glass.
  • an air-impermeable plastic coating can also be arranged on an air-permeable material as the upper cover layer 22' in order to achieve the airtightness of the upper cover layer 22'.
  • Recesses A are provided in the core layer 21', in which the electrical devices, such as evacuation means, in particular the pump, air exchange means, in particular at least one fan 81', and sensors, in particular at least one humidity sensor 82', are arranged. Motors or other components of the lifting means can also be partially installed in the recesses A.
  • At least one air duct which is necessary for the exhaust air of the fan 81', and at least one evacuation duct, which interacts with the pump and is necessary for generating a negative pressure or vacuum within the drawer interior R.
  • All electrical components are mechanically mounted by means of a 20' printed circuit board and electrically connected to each other and to the control system.
  • the core layer 21' can be made of a rigid plastic foam or a honeycomb plastic structure or a solid plastic layer, whereby the necessary recesses A must be arranged.
  • the evacuation channels and/or air channels can be cut out of the material of the core layer 21'.
  • Conductor tracks, to which the electrical loads are connected, are arranged on at least one side of the circuit board 20'. Contacting the electrical components, or the components to be controlled by the controller, and the controller on the circuit board 20' is simple and straightforward.
  • the circuit board 20' is part of the sandwich-like cover 2 and is preferably installed oriented such that the conductor tracks point toward the drawer interior R. There is no disruptive cabling within the cover 2 that continues outside the cover 2 in the drawer body 9. The manufacture of the cover 2 is simplified, and the susceptibility to errors during the lifting movement of the cover 2 is minimized.
  • a lower cover layer 22" with the same properties as the upper cover layer 22' can be used as part of the sandwich structure.
  • This lower cover layer 22" is attached to the circuit board 20' on the drawer interior side.
  • holes must be arranged in the circuit board 20' and the optional cover layer 22" so that the drawer interior R or the interior of the containers 14 can be pumped out.
  • a layer of sealing profiles 31' is arranged on the drawer interior side, thereby improving the sealing against the edges of the containers 14 or the sealing fittings 15.
  • the sealing profiles 31' are detachably attached and thus removable for cleaning purposes.
