A nozzle for a cleaner includes a nozzle housing including a suction flow path through which air including dust flows and at least a portion of which extends in a front and rear direction. First and second rotation cleaning units are arranged on the lower side of the nozzle housing to be spaced apart from each other in a lateral direction. Each of the first and second rotation cleaning units includes a rotation plate adapted for attachment of a mop. A first driving device including a first driving motor drives the first rotation cleaning unit and a second driving device including a second driving motor drives the second rotation cleaning unit. A water tank mounted on the nozzle stores water to be supplied to the mop.

Nozzle for cleaner

A cleaner station includes: a housing; a dust collecting motor configured to generate a suction force for sucking dust in a dust bin of a cleaner; a dust collecting part disposed at an upper side in a gravitational direction of the dust collecting motor; a coupling part including a coupling surface to which the cleaner is coupled; and a fixing unit configured to fix the cleaner when the cleaner is coupled to the coupling part, thereby allowing a user to seal the cleaner without applying a separate force.

Station for cleaner

Disclosed are an organometallic compound represented by Formula 1, an organic light-emitting device including the same, and an electronic device including the organic light-emitting device: The detailed description of Formula 1 is the same as described in the present specification.

Organometallic compound, organic light-emitting device including the same, and electronic apparatus including the organic light-emitting device

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.

Vacuum cleaner station, vacuum cleaner system, and method for controlling vacuum cleaner station

A cleaner system includes: a cleaner which includes a dust bin having one openable side thereof; and a cleaner station on which the cleaner is mounted. The cleaner includes: a first discharge cover which covers a portion of the open side of the dust bin; and a second discharge cover which covers the rest portion of the open side of the dust bin. The cleaner station includes a dust collection motor which generates a suction force sucking dust within the dust bin. Therefore, the suction force of the dust collection motor is concentrated by opening the second discharge cover first, so that adsorbed small dust is more easily sucked. Large dust is sucked by opening the first discharge cover after the small dust is sufficiently sucked, so that dust is efficiently discharged under the general power of the dust collection motor.

Cleaner system

A cleaner can include a cleaner main body including a suction motor configured to generate a suction force to suction air containing dust on a cleaning surface, the cleaner main body being configured to separate the dust from the air suctioned; a nozzle placed on the cleaning surface and configured to suck the air containing dust on the cleaning surface; and an extension tube to which the nozzle is detachably connected, one end connected to the nozzle and the other end connected to the cleaner main body to guide the air containing dust from the cleaning surface to the cleaner main body.

A photodetector includes a gate electrode extending in a first direction, a ferroelectric layer on the gate electrode and maintaining a state of polarization formed by a gate voltage applied to the gate electrode, a light absorbing layer on the ferroelectric layer and extending in a second direction intersecting the gate electrode, the light absorbing layer including a two-dimensional (2D) material of a layered structure, a source electrode on the ferroelectric layer and connected to a first end of the light absorbing layer, and a drain electrode on the ferroelectric layer and connected to the a second end of the light absorbing layer.

Photodetector and image sensor including the same

A negative differential resistance device includes a dielectric layer having a first surface and a second surface opposing the first surface, a first semiconductor layer that includes a first degenerated layer that is on the first surface of the dielectric layer and has a first polarity, a second semiconductor layer that includes a second degenerated layer that has a region that overlaps the first semiconductor layer and has a second polarity, a first electrode electrically connected to the first semiconductor layer, a second electrode electrically connected to the second semiconductor layer, and a third electrode on the second surface of the dielectric layer and which has a region overlapping at least one of the first semiconductor layer or the second semiconductor layer.

Negative differential resistance device

Provided are an organometallic compound represented by Formula 1, an organic light-emitting device including the organometallic compound, and a diagnostic composition including the organometallic compound:M(L)(L)  Formula 1wherein M, L, L, n1 and n2 are each independently the same as defined in the specification.

Organometallic compound, organic light-emitting device including the organometallic compound, and diagnostic composition including the organometallic compound

An embodiment of the disclosure relates to a foldable electronic device including a plurality of cameras, providing a preview image of a camera in response to folding or unfolding of the device and an operating method thereof. A foldable electronic device according to an embodiment of the disclosure may include: a plurality of cameras, at least one display, at least one processor operatively connected with the plurality of the cameras and the at least one display, and at least one memory operatively connected with the at least one processor, and the at least one memory may store instructions which, when executed, cause the at least one processor to: while a first preview image corresponding to a first camera among the plurality of the cameras is displayed on the at least one display, select at least one other camera, based on an analysis result of at least one object included in the first preview image, in response to detecting folding or unfolding of the electronic device, display a second preview image corresponding to the selected at least one other camera, and obtain a captured image based on the displayed second preview image.

Electronic device for providing camera preview image and operating method thereof

A nozzle for a cleaner has a nozzle housing including a suction flow path configured to allow air and dust to flow therethrough. A water tank is mounted on the nozzle housing to store water. The nozzle also has first and second rotation cleaning units arranged on a lower side of the nozzle housing. Each of the first and second rotation cleaning units include a rotation plate coupled to a mop. The nozzle includes a first driving device that has a first driving motor to drive the first rotation cleaning unit. The nozzle also includes a second driving device that has a second driving motor to drive the second rotation cleaning unit. Further, the nozzle has a water discharge port provided at a bottom of the nozzle housing to supply water in the water tank to each of the first and second rotation cleaning units.
