A nozzle part and a robot cleaner including same are disclosed. A nozzle part according to various embodiments of the present invention comprises: a brush for collecting waste such as hair; and a removing member for removing the waste, such as hair, that is stuck to the brush. The removing member more quickly rotates than the brush in the same direction to remove the waste, such as hair, that is stuck to the brush. Therefore, the waste such as hair can be easily collected, removed and captured. Thus, user convenience can be improved.

Nozzle part and robot cleaner including same

Disclosed are a conversion member and an electric cleaner. The conversion member according to embodiments disclosed herein may be detachably coupled to a handle included in a main body and a pipe. Then, the main body may be connected to an intake port located at the lowest position, and the pipe may be connected to an extension handle, allowing the main body to be located at a lower position facing the intake port. Thus, the electric cleaner may have a low center of gravity. Further, when the conversion member is detached, the pipe may be located between the main body and the intake port to be connected to the main body and the intake port, respectively. Accordingly, the main body may be located at an upper position directed away from the intake port, allowing the electric cleaner to have a high center of gravity.

Conversion member and electric cleaner including the same

A cleaner is disclosed, which comprises a main body including an suction inlet through which air containing dust enters, a dust separator provided to separate dust from the air while the air entering from the suction inlet is moving, a first dust collector configured to collect the dust separated by the dust separator, a cyclone portion configured to rotate the air to separate the dust from the air, and a second dust collector collecting the dust separated by the cyclone portion. The dust separator is provided with a plurality of plate shaped members arranged at a predetermined angle with respect to a moving direction of the air, and arranged to be spaced apart from one another to move the air.

Cleaner

The present disclosure discloses a dust collector for a vacuum cleaner, including a first cyclone disposed within an outer case to filter out dust from air introduced from an outside thereof and introduce the air from which dust has been filtered out to an inside thereof, a second cyclone accommodated in the inside of the first cyclone to separate fine dust from the air introduced to the inside of the first cyclone, a first guide vane spirally extended from an annular shaped first space between the first and the second cyclone to induce rotational flow so as to introduce air introduced into the first space to an inlet of the second cyclone, and a second guide vane spirally extended along an inner circumference of the inlet to enhance the rotational flow of air introduced to an inside of the second cyclone through the inlet.

Dust collector for vacuum cleaner

A cyclone type dust collector includes a first cyclone comprising a first cyclone body configured to induce a cyclonic flow of air around a first flow axis extending in a vertical direction, a first air inlet formed in the first cyclone body, a first dust outlet formed in the first cyclone body, and a first air outlet formed in the first cyclone body; and a first dust container configured to communicate with the first dust outlet and collect dust separated from the air, wherein at least a part of the first cyclone body is horizontally adjacent to the first dust container in a first horizontal direction that intersects with the first flow axis.

Cyclone type dust collector and cleaner having the same

The present disclosure discloses a dust collector for a vacuum cleaner including a first cyclone installed within an outer case to filter out dust from air inhaled from an outside thereof and introduce the air from which dust has been filtered out into an inside thereof, a plurality of second cyclones accommodated in the inside of the first cyclone to separate fine dust from the air introduced to the inside of the first cyclone, and a cover member disposed to cover an inlet of the second cyclone, wherein cyclones disposed adjacent to each other among the first and the second cyclones limit a first space within the first cyclone, and the cover member forms a second space communicating with the first space between the inlet and the cover member, and a guide vane extended in a spiral shape along an inner circumference thereof is provided at the inlet to induce rotational flow in air introduced to an inside of the second cyclone through the first and the second space.

A vacuum cleaner includes a first cyclone configured to separate dust from air introduced together with foreign objects from a lower side thereof and discharge the separated dust to a first dust storage chamber through an outlet provided at an upper portion thereof, a plurality of second cyclones arranged on an inner circumferential surface of the case and configured to separate fine dust from air which has passed through the first cyclone and discharge the separated fine dust to a second dust storage chamber differentiated from the first dust storage chamber, and a lower configured to form bottom surfaces of the first dust storage chamber and the second dust storage chamber.

Vacuum cleaner

A dust collector for a vacuum cleaner disclosed herein includes an outer case forming a lateral appearance of the dust collector, and provided with a first cyclone unit capable of filtering out dust from externally-introduced air and allowing an introduction of the dust-filtered air therein, and an upper case coupled to an upper portion of the outer case to cover the first cyclone unit, the outer case including a second cyclone unit capable of separating fine dust from the air introduced into the first cyclone unit, and a fine dust collecting unit capable of collecting the fine dust separated through the second cyclone unit, wherein the second cyclone unit includes a left cyclone portion and a right cyclone portion disposed at both left and right sides of the fine dust collecting unit and each having outlets, each of the outlets communicating with an inside of the fine dust collecting unit.

A dust collector for a vacuum cleaner, including a first cyclone disposed within an outer case to filter out dust from air introduced from an outside thereof and introduce the air from which dust has been filtered out to an inside thereof, a second cyclone accommodated in the inside of the first cyclone to form a first space between the first cyclone and the second cyclone to separate fine dust from the air introduced to the inside of the first cyclone, and a guide vane spirally extended along an inner circumference of the second cyclone to induce rotational flow to the air introduced to an inside of the second cyclone through an inlet of the second cyclone via the first space, wherein the guide vane is integrally provided on the second cyclone.

A dust collector for a vacuum cleaner disclosed herein includes a first cyclone that is configured to separate dust from air introduced from a lower portion thereof with containing foreign materials and discharge the separated dust into a first dust storing unit, a second cyclone that is configured to separate fine dust from the air, from which the dust has been separated by the first cyclone, and discharge the separated fine dust into a second dust storing unit defined in a second case, and a lower cover that is coupled to the first case by a hinge so as to define a bottom surface of the first dust storing unit, the second dust storing unit and the first cyclone upon being closed, and discharge therethrough the foreign materials collected in the first dust storing unit, the second dust storing unit and the first cyclone upon being open.
