Title: Vacuum cleaner suction equipment for floor cleaning
Inventor: KITAMURA SHUSUKE
IPC: A47L9/04
Filed: 1988-12-27
Abstract: PURPOSE:To prevent the rotation of main and sub agitators from being locked due to fibred dust intrusion into bearings, by a method wherein the main agitator and the sub-agitators located at the ends of the main agitator are attached in a suction main body, and the sub-agitators are provided with flexible agitating blades on the sides of the suction main body facing outside. CONSTITUTION:When agitating blades 45 scrape out thin and long fibred dust such as hair, etc., which is sucked in the rotating direction before it it sent to a cleaner main body through paths 47 and 48 and a suction chamber 26, the fibred dust winds around the neck of the three agitating blades on a main agitator 32 side. When this phenomena happens repeatedly causing an increase in the accumulation of the fibred dust and the fibred dust begins to wind tight, the end of dust emerges from openings 37 or 38, and the agitator blades 45 displace towards the inner circumference side of a rotor 44 due to the tight winding of dust, and the dust drops out of the sub-agitators 36 and plunges towards the suction main body 21 side. Thereby, the fibred dust is prevented from intruding into the axis penetrating parts of bearings 33 and 34, so that the rotation lock of the main and sub-agitators 32 and 36 is prevented.

Abstract: PURPOSE:To detect and remove ground noise which occurs on a main sensing plate for detecting an obstruction by means of an auxiliary sensing plate by disposing the ground within a sensitivity distribution area of the main sensing plate to be included in a sensitivity distribution area of the auxiliary sensing plate. CONSTITUTION:In an auxiliary sensing plate 14, a capacity Cc2, a divided capacitor C12, and a loading coil L2 are adjusted so that a resonance frequency f12 may approach the frequency f02 of an oscillation circuit OSC2 to be used in that frequency. After the output is detected by a wave detector D3, D4, it is amplified by a return type direct current amplifier ADA2, made binary by a comparator Comp2 and inputted into a monostable multivibrator 17. When the auxiliary sensing plate 14 senses unevenness of the ground, the output of the oscillation circuit OSC2 decreases, and the comparator Comp2 becomes plus and the monostable multivibrator 17 generates a minus pulse. This serves as a reset circuit which discharges the capacitor C1 of the return direct current amplifier ADA1.
