Definitions

• the present invention describes a drawer device, comprising a drawer body, a drawer that can be moved linearly therein and a cover that can be moved in a lifting direction by means of lifting means relative to the drawer and to the drawer body, so that a controlled relative movement of the cover in the lifting direction can be carried out by means of the lifting means and a controller
• Evacuation and / or dehumidification of a drawer interior is made possible after bringing the lid into the closed position and a lid of a drawer device with a drawer in a drawer body, with the lid closed an evacuation and / or dehumidification of the drawer interior is made possible and lifting means are arranged on or in the lid.
• Refrigerators for storing food have some disadvantages, since a lot of electrical energy is constantly required in order to continuously and massively cool an interior. The interior climate of the refrigerator has received little attention so far.
• the Hygiene Council which carried out an international study called the Hygiene Report 2010, the refrigerator is more contaminated with around 11,400,000 germs per square centimeter than a toilet with around 100 pathogens per square centimeter.
• This report in 2010 received a lot of media coverage, but apart from recommendations to clean the refrigerator more often, no noticeable improvements have so far taken place.
• the drawer device comprises a drawer with walls and a drawer interior, the drawer being operatively connectable to a cover and being mounted so as to be linearly movable within a drawer body. More precise details about the drawer, the lid, possibly lifting means and evacuating means are largely left open in DE202017006169.
• the interior of the drawer will be evacuated to a slight negative pressure, below atmospheric pressure, which is generated and maintained in a controlled manner. In this way, food can be kept edible or edible for longer in a simplified manner.
• Storage in the drawer body with drawer equipment requires less energy than the refrigerator, since the oxygen deprivation in the interior is completed after a few minutes and afterwards almost no further electricity is required.
• a drawer unit can be implemented without using harmful materials such as refrigerants or thermal insulation.
• the consumption of plastic bags with the known vacuuming by means of vacuum sealing devices can be significantly reduced and yet food can be stored for longer periods of time without any problems.
• Using drawer devices food can be stored in a simpler, more environmentally friendly and more energy-efficient manner. This has a positive effect on the quality of the food and the health of the consumer.
• the drawer body forms the outer shell in which the lid and the drawer are movably protected.
• Lifting means and evacuating means which can be operated electrically via a control, are arranged in the cover or the drawer, so that evacuation is enabled in a controlled manner when the cover is placed on the drawer. Air can be pumped out of the interior of the drawer through an air duct. If sensors are arranged, the evacuation can run automatically and the ventilation before the opening of the drawer can also be recognized and automatically initiated by the control.
• the lifting means known so far from WO2019 / 141574 do their job well and the cover can be lowered precisely onto the drawer in a controlled manner by means of a control and can be removed again linearly from the drawer in the lifting direction.
• the lifting means are electrically driven and controlled. In some cases, the closing effect in the known solution leaves something to be desired, since the cover does not seal sufficiently from the outside.
• the present invention has set itself the task of improving a drawer device for evacuating and / or dehumidifying the interior of the drawer and a lid in such a way that the user-friendliness is increased when closing, the energy consumption is reduced and a reliable, reproducible movement of the lid in the stroke direction and sealing storage of the Lid on the drawer is reached.

• the drawer device 0 is denoted here as a whole with 0 and comprises a drawer 3 with a drawer interior R and a cover 2 that can be moved relatively in a lift direction H by means of lifting means 7 and designed to be movably mounted and evacuated and / or dehumidified.
• the drawer 3 can be operatively connected to the cover 2 and is mounted within a drawer body 9 so that it can be moved linearly in a pushing movement direction S.
• the drawer body 9 forms the outer shell in which the cover 2 and the drawer 3 are movably and protected.

With the drawer interior R, the interior of the container 14 can also be evacuated.
• the containers 14 are preferably designed as standard gastronorm containers, the interiors of which can form the entire interior of the drawer R, which can be closed and evacuated and / or dehumidified by means of a cover 2.

• a mounting bracket 19 is selected here as the fastening means, but a web or the like molded onto the drawer body 9 could also serve as the fastening means.
• lifting means 7 are arranged, which hold the cover 2 within the drawer body 9 so as to be movable in the lifting direction H.
• the lifting means 7 are operated with a control, not shown, to which, as here, a control button 104 'and a closed position sensor 29' can be connected. Only when the closed position sensor 29 ′ signals that the drawer 3 is in the closed position below the cover fixed in the pushing direction S, the lifting means 7 are activated in order to lower the cover 2 onto the drawer 3.
• the cover 2 of the drawer 3 or the containers 14 can be raised in an oppositely controlled manner and can also be lowered onto them again.
• the lifting means 7 are of course electrically driven and controlled by means of a controller. This results in the lifting movement of the cover 2 in the lifting direction H perpendicular to the pushing movement direction S of the drawer 3.
• the containers 14 within the drawer 3 of the drawer device 0 can be closed as a whole compared to conventional drawers by the user closing the drawer 3 by hand the lid 2 in the closed position of the drawer 3 lowers onto the container 14 and closes it airtight from above.

• Possible dehumidifying agents can be arranged in a similar manner in the cover 2 and can be operated by means of a controller.
• the lifting means 7 are designed here in the form of a special lifting mechanism, the components of which are controlled electromechanically by means of the controller.
• the lifting means 7 are at least partially integrated into the edge area of the lid 2 and interact with the drawer body 9 so that the lid 2 can be displaced relative to the drawer 3.

• the motor 71 ' is fastened to the cover 2 with a motor mount 72'.
• the lifting means 7 have an end block 73 'and a mounting block 74' on both sides.
• the motor 71 ' transmits its power via a shaft coupling 76', which indirectly transfers power to both linear carriages 792 'by means of a bearing bush 793', with the motor 71 'stationary or locally fixed relative to the cover 2 or a cover surface.
• a lifting profile 75 ' is mounted between the end blocks 73' and the mounting blocks 74 ', which can be moved in the lifting direction H by the linear carriage 792' and thus indirectly by the motor 71 '.
• the lifting profile 75 ′ can be moved relative to the other components of the lifting means 7.
• the lifting profile 75 ' is here attached to the mounting bracket 19 of the drawer body 9, so that when the lifting profile 75' is held on the fastening means, the cover 2 and the remaining lifting means 7 can be moved in the direction of the drawer 3 or in the opposite direction.

• One possibility for coupling the at least one linear carriage 792 'to the lifting profile 75' is the formation of slots in the side surfaces of the lifting profile 75 'and the formation of engagement webs 800 on at least one side surface of each linear carriage 792'. Particularly preferred is the formation of engagement webs 800 on two opposite side surfaces of each linear carriage 792 '.
