Description

  The present invention relates to a floor nozzle for a vacuum cleaner and a vacuum cleaner using the same.

Conventionally, a cleaning body such as a brush has been used for cleaning the floor surface, and a rotary rotor has been used to efficiently lift the floor. A blade, brush, woven fabric, or the like is used as the cleaning body, and the cleaning body is twisted to reduce rotational fluctuation.
For example, Japanese Patent Laid-Open No. 7-178016 discloses a configuration in which blades are spirally attached to an outer peripheral surface of a metal rotor as a rotary rotor of a suction nozzle for a vacuum cleaner. Japanese Patent Application Laid-Open No. 2004-344267 discloses a twisted torsion brush made of stainless steel and a manufacturing method thereof.

  In order to reduce rotational fluctuation when contacting the floor, it was necessary to twist the cleaning body by some method. For this purpose, a rotating rotor is created by inserting a cleaning body such as a raised cloth into the twisted groove of the rotor mandrel.

  Conventional cleaning bodies use brushed cloth, woven cloth, blades, etc. Brushed cloth and woven cloth are woven thin fibers, and the fluff of the brush part is soft, and the blade has a flapping effect. The brush portion is formed of a soft material having a problem, and the raised cloth, the woven cloth, and the blade have a problem that there is little effect of scavenging dust, which is the original purpose of cleaning.

  If you make a channel brush using a brush material with a thick wire diameter, you can create a strong bristle-cleaning body and twist multiple channel brushes created in this way. Although a brush assembly has also been devised, since there is no rotor mandrel at the center, there has been a problem that when external pressure is applied, the central part of the brush assembly is easily deflected, causing a runout at high speed.

The channel brush is formed of a cleaning body A formed of a bristle brush having a large wire diameter, a cleaning body B formed of a soft blade, a cleaning body C formed of a wiping cloth and a base, and a raised cloth. The cleaning body D, the cleaning body E formed of a woven fabric and a resin, and a belt-like body are used, and at least one of the channel brushes is used. Further, the cleaning body is fixed to the rotor mandrel by a fixing means at an arbitrary position in the longitudinal direction of the rotating rotor, and the cleaning body is spirally arranged in the opposite direction from the fixed position. It is. Also, a fixing member for holding the channel brush, the rotor mandrel is sandwiched at a substantially central portion in the longitudinal direction of the rotating rotor, and arranged in a spiral shape in the opposite direction with the fixing member as a boundary. is there. Moreover, the outer periphery of the fixing member is subjected to flocking processing, and a floor nozzle for a vacuum cleaner excellent in cleaning performance can be provided. Moreover, the vacuum cleaner of this invention is equipped with the electric blower which generate | occur | produces an attractive force, the dust collection chamber which collects dust, and the floor nozzle for vacuum cleaners of any one of Claims 1-5.
