- the freshness container 1 has a trigger mechanism 28 for activating the drive device 20 and the lifting motors 23, with which first the container lid 3 can be lifted and then the container base body 2 can be moved in the opening direction 29.
- a trigger mechanism 28 is arranged on the drive device 20 and a trigger mechanism 28 is arranged on the freshness container 1, wherein one trigger mechanism is designed in the form of a button 30 and one trigger mechanism is designed as a proximity sensor 31.
- An exemplary method for opening the fresh-keeping container 1 can be carried out as follows:
- the trigger mechanism 28 detects an opening request by an operator of the fresh-keeping container 1 by means of an over-pressing movement on the drawer 37, the container lid 3 is raised relative to the container base bodies 2 via the trigger mechanism 28 and the container base bodies 2 are moved with a time delay relative to the furniture body 21 in the opening direction via the trigger mechanism 28 and by the drive device 20.
- a lifting movement of the container lid 3 is also possible during the opening movement of the container base body 2, wherein a release process of the container lid 3 takes place simultaneously with or during the linear movement of the container base body 2 in the opening direction 29.
- a plurality of valves 34 are arranged on the container lid 3 in connection with a hose system 35 ( schematically indicated in dotted lines ) of the container lid 3 for detecting and changing the atmosphere 6 .
- Fig. 5 shows that a guide device 24 is arranged on the container lid 3, by means of which the container lid 3 can be lifted relative to the container base bodies 2 via the lifting motors 23.
- the guide device 24 comprises an inclined plane 25, which is designed as a groove 26 and in which a sliding block 27 is arranged.
- the container lid 3 and the container base body 2 are hermetically connected to one another by sealing means 19, wherein the sealing means 19 are indicated schematically in dotted lines.
- Container base body 2 comprises, wherein the shape, number and positioning of the container base body 2 is generally arbitrary.
- the container base bodies 2 have different length and width dimensions as varying dimensions 33.
- exactly one container lid 3 is provided for the plurality of container base bodies 2, wherein the control and/or regulating device 4 is programmed to individually adapt the atmospheres 6 of the plurality of container base bodies 2.
- the container base bodies 2 are made of metal.
- the container lid 3 is made partly of metal and partly of wood, whereby it is preferred that the container lid 3 is made of metal in some areas - in the closed position in the area of the container base bodies 2.
- Fig. 7 visualizes the components of the freshness container 1 in the form of a circuit diagram.
- a large number of valves 34 are connected to the three container base bodies 2, which in turn are connected to an air inlet 43 and (in this embodiment) three air outlets 44.
- a filter 41 is provided between the ventilation device 16 and the pressure adjustment device, whereby, for example, the adjacent supply container 12 can be dispensed with.
- a liquid container 42 is connected between a valve 34 and an air outlet 44, via which condensate bound from the atmosphere can be removed - however, this is generally not absolutely necessary.
- moisture can be transported away or ventilated via lines.
- liquid can be transported away from the freshness container 1 or an interior of the freshness container 1 by evaporation in a collecting tray on the fan 8 and/or the Peltier element 15 from the furniture body 21 via ventilation slots, through a hose 35 and/or through the liquid container 42 in the form of a collecting container for condensate.
- a computer-implemented method for controlling the atmosphere 6 of the freshness container 1 can be explained as follows:
- the control and/or regulating device 4 determines sensor data from the sensor system 5 with regard to the existing CO2 content, the temperature or the proportion of organic compounds within the atmosphere 6 of the container base body 2 or the atmospheres 6 of the container base body 2 and adapts the atmosphere(s) 6 according to predefined or desired atmosphere properties/compositions.
- a computer program product can be provided as an algorithm, which comprises commands which, when executed by a computing unit, cause the computing unit to carry out the method for regulating the atmosphere 6.
- the computer program product can be stored on a volatile or non-volatile storage medium or transmitted via a data signal.
