A method for monitoring a drawer interior of a vacuum drawer device when the lid is supported by the drawer airtight and closed, includes: periodic measurement of the relative humidity with a humidity sensor arranged in the path of a dehumidifying channel in the lid or, respectively, the drawer interior; comparison of the measured relative humidity with an upper threshold; and as soon as the measured relative humidity is above the upper threshold, opening the valve and inducting a ventilator arranged in a recess or in the path of a dehumidifying channel in the lid. Fresh air is sucked through an air inlet opening, circulated, and thereafter released again from the dehumidifying channel and the drawer interior communicating therewith, until the relative humidity reaches a lower threshold measured by the humidity sensor. Then the valve is closed, the ventilator is stopped, and the controller switches into the humidity monitoring mode.

A refrigerator includes: a cabinet having a storage space; a door including a door unit to open or close the storage space and a drawer unit to provide a receiving space; a driving device disposed at the door unit and configured to provide power; and an elevation device disposed at the drawer unit, connected with the driving device, and configured to move up or down, in which the driving device includes: a motor assembly including a driving motor, a screw rotated by power from the driving motor and extending in an up-down direction, and a movable unit to move up and down along the screw; and a pair of lever units connected to the movable unit at both sides of the motor assembly, and each of the pair of lever units includes: a first lever connected to the movable unit; and a second lever connected with the first lever and connected with the elevation device.

A method of configuring a storage system includes the steps of: sending a command to one or more units in the electronic system to enter into an address setting mode; generating a signal for a user to identify units that have entered the address setting mode; and setting up an address for a unit based on an input received from the user.

A drawer assembly is described that includes one or more mini-drawer assemblies. A mini-drawer assembly comprises a sliding tab along a rear-to-front axis, a release mechanism coupled to the sliding tab, and a body having a body bottom coupled from the body bottom to the sliding tab. The body may slide over the sliding tab. The mini-drawer assembly may include a plurality of compartments in the body and a plurality of lids that are hingedly coupled to the compartments. Each lid may have a respective fastening element. A plurality of latches may couple to the body such that each latch is coupled to a corresponding compartment. The latch may hold the respective fastening element of the lid. When the body is pulled out along the rear-to-front axis, the release mechanism may engage with the latch to release the respective fastening element and to unlatch the lid of the compartment.

A refrigerator includes a cabinet defining a storage chamber, a drawer door, a motor assembly provided at the storage chamber and configured to provide a driving force that moves the drawer door relative to the storage chamber, and a rack gear assembly provided at the drawer door and having an extendable rack gear. The rack gear includes a fixed rack fixed to the drawer door and a moving rack slidably coupled to the fixed rack. The drawer door includes a drawer part that defines an upwardly open storage space, and a door part that is configured to, based on the drawer door being inserted into the storage chamber, close the storage chamber.

A refrigerator may include a rack gear assembly provided on a lower surface of a drawer. The rack gear assembly may have a first rack member and a second rack member that are pushed out by being moved forward sequentially so that a pushing-out distance of the drawer is maximized and the drawer is fully closed even when opposite sides thereof are pushed in a storage chamber without being in parallel.
