Patent JP-H0257224-A (JP)
Title: Vacuum cleaner
Inventor: TAKASHIMA YOSHINORI
IPC: A47L9/28
Filed: 1988-08-24
Abstract: PURPOSE:To clean effectively and efficiently without damaging a floor surface because of a brush rotating at a high speed by a method wherein a rotating speed of a rotary brush is varied at the same rate as a rotating speed of a blower motor and not only a suction force suitable for cleaning but also the rotating speed of the rotary brush are varied. CONSTITUTION:In an electric circuit, since a rotary brush motor 23 is connected in parallel with a blower motor 2, the control of rotating speed either by means of a variable resistor 1 or by means of a dust sensor circuit 7 varies a rotating speed of the blower motor 2 and also varies a rotating speed of the rotary brush motor 23 connected in parallel with it. When dust does not pass through a dust sensor part 17, the blower motor 2 rotates at a rotating speed less by a fixed rate compared with the rotating speed preset by an operating part 14 at hand. At the same time, the rotary brush motor 23 also rotates according to the rotating speed of the blower motor 2. On the other band, when the dust sucked is detected by the dust sensor part 17, the blower motor 2 rotates at the same speed as the rotating preset by the operating part 14 at hand. At the same time, the rotary brush motor 23 also increases the rotating speed according to the rotating speed of the blower motor 2. This cleaner is therefore operated quietly at a low speed suitable for cleaning and can so clean that the rotary brush does not too damage a floor, when there is a small quantity of dust.
