An air flow sensing unit, which may sense an amount of air flowing or an pressure for air flown into the cleaning apparatus by a suction motor or an impeller and inform a user of a time for emptying a dirt collecting receptacle of dust or dirt and/or a time for cleaning or replacing a filter with a new one, and a cleaning apparatus having the same are provided. The unit may include an air flow pipe to fluidly communicate an air flow passage of a cleaning apparatus with the outside, and an indicator positioned in the air flow pipe to be lifted based on a change in amount of air flowing or air pressure generated by air movement in the air flow passage and to be lowered due to a weight thereof.

A nozzle assembly of a vacuum cleaner is provided that includes a casing, a suction port, a drum brush, a fan, and a blocking plate. The drum brush is rotatably disposed in the casing so drum bristles hit a surface being cleaned. The fan is disposed in the casing to be rotated by air drawn in through the suction port so that the fan rotates the drum brush. The blocking plate is adjacent to the front of the fan to screen most of the fan except for a lower portion of the fan. The fan includes a circular fan body, a shaft member, and a plurality of blades. The inside edge of each of the blades is at a distance from the shaft member so that the drawn-in air passes through a space defined between the inside edge of each of the blades and the shaft member.

Nozzle assembly of vacuum cleaner

A cleaner having a handle assembly rotatable in all directions is disclosed, the handle assembly including a housing; a handle which is capable of being gripped by a user; a connection unit which connects the handle with the housing to rotate in all directions; and an elastic unit which elastically biases the handle to a neutral position. As the handle is capable of rotating in all directions, a user can clean a surface without feeling strain in his or her joints.

A suction port assembly and vacuum cleaner having the same is disclosed. The suction port assembly includes a casing comprising a suction port which draws in dust from a surface being cleaned; a drum brush which is disposed rotatably in the casing, on an external surface of which a plurality of bristles are arranged to shake off dust from the surface being cleaned; and a rib which is disposed at a position close to the drum brush, is mounted in the casing so that its one end is in contact with the bristles, and detaches the dust from the bristles when the drum brush rotates; and wherein the bristles are contacted on a slant relative to the rib to prevent the drum brush from rotating when the casing is pulled towards a user.

Suction port assembly and vacuum cleaner having the same

A vacuum cleaner is disclosed which comprises a motor chamber for mounting a motor assembly that, generates a suction force at a dust suction port, and a discharge port for guiding an air discharged from the motor chamber to the outside of a cleaner body, wherein the motor chamber comprises an air discharge opening which is in fluid communication with the discharge port; and a path extension member disposed between the motor assembly and the air discharge opening, of which edges are spaced apart from an inner wall of the motor chamber by a predetermined distance, respectively, to thereby form a detour path, and the air discharged from the motor assembly is guided in a circuitous manner by the path extension member so as to be passed through the detour path before reaching the air discharge opening. That assembly effectively reduces noise generated during operation of the motor assembly that is detectable outside of the cleaner body.

Vacuum cleaner

A cyclone separating apparatus and a vacuum cleaner having the same are provided. The cyclone separating apparatus includes a cyclone body including a cyclone chamber and a dust collecting chamber, a cover unit connected to an upper portion of the cyclone body, a door unit openably mounted to a bottom portion of the cyclone body, and at least one noise reducing rib formed in an air discharging pipe in the cyclone chamber.

A suction nozzle of a vacuum cleaner includes jet units for jetting air into positions where air streams collide with each other as air is drawn into a suction port of the nozzle from both side portions thereof, so as to prevent substantially the collision of air streams.

Suction nozzle for a vacuum cleaner

A fan assembly for a vacuum cleaner, comprising a motor, an impeller rotatably coupled to the motor, and having a plurality of impeller wings, and a diffuser having a plurality of diffuser wings arranged along an outer circumference of the impeller. The plurality of diffuser wings includes first and second parts, the second part extending from an angle of the first part adjacent to the outer circumference of the impeller.

Fan assembly for vacuum cleaner

A suction brush assembly comprises an assembly body having a suction inlet for drawing in dust on a surface being cleaned, a cover connected to the assembly body and having an opening for drawing in an external air, and a rotation body rotatably mounted to the assembly body and mounting a detachable cleaning member at a lower part thereof for contact with the surface being cleaned. The external air drawn in through the opening flows out to a lower part of the assembly body through a gap formed between the rotation body and the assembly body. Accordingly, the dust can be prevented from flowing into the rotation body, thereby improving an efficiency of a cleaning work.

Suction brush assembly and a vacuum cleaner having the same

A robot vacuum cleaner comprises a cleaner body having a wheel disposed at a lower portion and a suction port through which contaminants are drawn in from a cleaning surface; and an air circulating mechanism for filtering out contaminants from the contaminant-laden air drawn in through the suction port and then jetting the contaminant-free air to an air jet opening to help dislodge contaminants from the cleaning surface. The air jet opening is adjacent to the suction port; and the two elements are surrounded by a sealing member for sealing off a portion between the cleaning surface and the cleaner body to prevent dislodged contaminants from being dispersed outwardly.
