A duplex washing machine with an automatically openable drawer comprises a base, a drawer, and an automatic ejection device. The drawer is positioned in a housing of the washing machine; an opening through which the drawer is pulled and pushed to be opened and closed is formed in the housing; the automatic ejection device is arranged under the drawer and comprises a device body and a telescopic rod; an extension end of the telescopic rod is fixed with the drawer; the other end of the telescopic rod extends into the device body; the device body is fixedly connected to the base of the washing machine; and the device body drives the drawer to move into or out of the housing through the telescopic rod. According to the duplex washing machine, a user can open or close the drawer through one-click operation, such as simply pressing a button or touching.

A refrigerator includes: a cabinet having a storage space; a door including a door unit configured 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 including a driving motor to provide power; and an elevation device disposed at the drawer unit, connected with the driving device, and configured to move up or down, the elevation device includes: a lower frame; an upper frame positioned over the lower frame; a scissor assembly configured to connect the lower frame and the upper frame; and a screw rotatably supported on the lower frame, configured to be rotated by driving force transmitted from the driving device disposed at the door unit, and connected with the scissor assembly.

A refrigerator may include a cabinet, a drawer, a driving part, a cable tray, and a rack gear assembly. Connecting members of the cable tray may be maintained in an anti-sagging state by a tray guide part, so that friction noise generated during moving of the cable tray is prevented and interference with the cable tray during moving of the drawer is prevented.

A method for operating an assembly includes providing a furniture part which can be arranged by a furniture drive in at least two operating positions relative to a furniture body. In chronological order, a command transmitter spatially separated from the furniture drive transmits at least one digital command to a data transmission device of the furniture drive via the data transmission device of the command transmitter. A computing unit of the furniture drive compares the at least one digital command with at least one digital data set stored in a storage unit, and the computing unit makes a selection on the basis of the result of the comparison to carry out the at least one digital command.

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 includes a rack gear assembly provided on a lower surface of a drawer, wherein the rack gear assembly has a first rack member and a second rack member sequentially moved forward such that an opening distance of the drawer is maximized, and a wing end of the second rack member and a blocking part of a bottom of a storage chamber are provided such that exact engagement of a rack gear with a pinion is maintained during opening of the drawer. In addition, while the drawer is opened, an unwanted movement of the drawer in a closing direction thereof is prevented.

A drive adapter for tool-free mounting of a drive element on a rail element of a guide system includes a drive carrier and a holding section. The drive carrier includes a mounting means for a drive element. The holding section includes two support surfaces and a holding ridge which connects the support surfaces at least in sections and defines a distance between the support surfaces. The two support surfaces are either each convexly curved, face away from one another and configured such that they can be clamped between two rolling element running surfaces of the rail element which face one another, or each concavely curved, face toward one another and configured such that they can be clamped onto two legs of the rail element and carry rolling element running surfaces which face away from one another.

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.
