A nozzle for a cleaner has a nozzle housing, which has a nozzle base and a drain hole for discharging water from the nozzle housing. The nozzle also has a rotary cleaning unit disposed below the nozzle housing. The rotary cleaning unit has a rotation plate that can be attached to a mop. The nozzle has a driving unit that includes a driving motor for driving the rotary cleaning unit. The nozzle also has a control board for controlling the drive motor. In addition, the nozzle has a water tank detachably mounted on an upper side of the nozzle housing. The water tank stores water and supplies the water to the rotary cleaning unit.

Nozzle for cleaner

A cleaner holder includes a base, a stand coupled to the base and extending upward from the base, a support body coupled to an upper portion of the stand and configured to support a cleaner, and a cleaning module support coupled to the stand and configured to support a cleaning module of the cleaner. The cleaning module may be detachably coupled to an extension tube of the cleaner.

Cleaner holder and cleaner unit

A cleaner holder comprises a base, a stand coupled to the base and extending upward from the base, a support body coupled to an upper portion of the stand and configured to support a cleaner, and a cleaning module support coupled to the stand and configured to support a cleaning module of the cleaner. The cleaning module may be detachably coupled to an extension tube of the cleaner.

A vacuum cleaner is provided. The vacuum cleaner may include a cleaner body having a suction head that communicates with the cleaner body and a suction motor assembly to generate a suction force. The suction motor assembly may include a motor, a motor housing having a chamber to accommodate the motor, a housing cover configured to cover the motor housing and provided with an air inlet, a circuit board provided at an outside of the motor chamber and having at least one heat generating component installed thereupon, and a heat sink provided at the chamber and in contact with the at least one heat generating component. An installation part to install the circuit board may be provided at the motor housing.

Vacuum cleaner

A vacuum cleaner includes a cleaner body, a suction hose mounted at a front surface of the cleaner body to suck in dust, moving wheels provided at both sides of the cleaner body, rotating to move the cleaner body and rotatably supporting the cleaner body, wheel motors connected to the moving wheels and rotating the moving wheels, a detecting unit provided in the cleaner body and sensing inclination of the cleaner body to determine whether the cleaner moves and stops, a plurality of detecting members provided at a front surface of the cleaner body and located at both sides of the suction hose to detect an obstacle, and a controller for controlling the wheel motors according to detected signals of the detecting unit and the obstacle detecting members.

A charging device is provided. The charging device includes an output terminal unit connected to an input terminal unit of a battery pack. The output terminal unit includes a terminal body including an output terminal connected to the input terminal unit and a terminal cover which covers the output terminal before the input terminal unit of the battery pack is connected to the output terminal unit and through which the output terminal passes while the input terminal unit of the battery pack is connected to the output terminal unit.

Charging device

Provided is a vacuum cleaner including a cleaner body; a dust container installed at the cleaner body and of which at least a part is exposed to an outside through a front surface of the cleaner body; a cover member installed to open and close a part of the cleaner body and configured to selectively accommodate an upper portion of the dust container; a suction hose of which one side is connected to a suction part for suctioning dust and the other side is connected to a front end of the cover member; a grip portion provided at the cover member and operated to open and close the cover member; and a locking assembly provided inside the cover member and disposed at both sides based on the suction part to be restricted in the cleaner body.

A vacuum cleaner that includes: a cleaner body; a wheel; a dust container; a cover member that is configured to (i) rotate, about an axis that is outside of a plane of the cover member, between a first position and a second position and (ii) cover, based on the cover member being located at the first position or the second position, the first opening of the cleaner body and a portion of the dust container; a cover member coupling portion that couples the cover member to the cleaner body and that is configured to rotate about the second axis with the cover member; a suction nozzle that is coupled to the dust container and that is configured to guide dust into the dust container; and a display that is coupled to the cover member and that is configured to display operating information of the vacuum cleaner is disclosed.

Provided is a vacuum cleaner including a cleaner body disposed at a position distant from the ground; moving wheels rotatably installed at both sides of the cleaner body and configured to rotatably support the cleaner body; a dust container installed at a front surface of the cleaner body located at a front of the moving wheels and configured to collect suctioned dust; and a suction hose connected to the front surface of the cleaner body and through which the dust is suctioned, wherein a center of gravity of the cleaner body is located at a rear side further than a vertical extension line of a rotating center of the moving wheels, and a rear end of the cleaner body becomes closer to the ground when travel of the vacuum cleaner is stopped.

The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner including a case detachably provided at a cleaner body to accommodate dust and of which an upper surface and a lower surface are opened; a cyclone provided inside the case to separate the dust; an upper cover configured to shield the upper surface of the case and having a suction port through which the dust is suctioned and a discharge port through which air separated from the dust is discharged; an upper locker rotatably installed at an outer surface of the case and configured to selectively restrict the upper cover; a lower cover configured to shield the lower surface of the case; and a lower locker slidably installed at the outer surface of the case and configured to selectively push and open the lower cover.
