A nozzle for a cleaner according to an aspect of the present invention comprises: a housing; and a rotation cleaning portion rotatably coupled to the housing and having a body part and a brush part which is coupled to the outer peripheral side of the body part. The brush part comprises: a first brush coupled to the outer peripheral side of the body part and extending in the radial direction of the body part; and a second brush disposed alongside the first brush. The first brush is disposed so as to come in contact with a floor surface prior to the second brush during the rotation of the rotation cleaning portion, and is less stiff than the first brush.

Nozzle for cleaner, and vacuum cleaner

A nozzle of a cleaner includes: a housing; a rotation cleaning unit accommodated in the housing and configured to clean a surface based on a rotation operation; and a drive unit inserted into a side of the rotation cleaning unit. The drive unit includes a motor, a motor supporter fixed to the housing and coupled to the motor, a gear unit connected with a rotation shaft of the motor to transfer a driving force, and a shaft connected to the gear unit and the rotation cleaning unit to transfer a rotation force to the rotation cleaning unit. The motor includes a printed circuit board (PCB) installation portion in which a PCB is installed and which is spaced apart from the motor supporter, in which a first space portion in which the air flows is formed between the motor supporter and the PCB installation portion.

Nozzle for cleaner

Provided is a vacuum cleaner. The vacuum cleaner includes a cleaner body provided with a suction motor at the inside thereof and a handle at the outside thereof, and a suction nozzle connected to the cleaner body. The suction nozzle includes a housing of which at least a portion of a front side is opened to defined a front opening, a rotation cleaning part which is installed inside the housing, of which at least a portion is exposed through the front opening, and which is configured to clean a floor surface by a rotation operation thereof, and a sealing part protruding downward from a lower end of the housing and provided in rear of the front opening.

Cleaner

A nozzle for a cleaner includes a nozzle body having a suction passage in which air flows. A water tank is detachably mounted on the nozzle body, and a rotation cleaning part is rotatably supported at a lower side of the nozzle body to receive water from the water tank for cleaning a floor. The water tank includes an outlet through which water is discharged, a valve configured to open and close the outlet, and an air hole configured to introduce outside air into the water tank. An air hole operation part is movably installed on the water tank to open and close the air hole.

A cleaner includes a nozzle assembly, a cleaner body in communication with the nozzle assembly, and a damp cloth-based wiping unit coupled to the nozzle assembly. The damp cloth-based wiping unit includes a water tank. The water tank includes a storage space defined therein for storing water, an air hole defined in a top face of the water tank for receiving external air, a discharging port formed on a bottom face of the water tank for discharging the water from the storage space, and a deformable member configured to be depressed inwardly into the storage space. A damp cloth is attached to a bottom face of the water tank for receiving the water discharged through the discharging port. A pressing mechanism is configured to selectively press and translate the deformable member.
