Abstract

PURPOSE:To prevent dust from adhering on detecting elements for improving the detecting accuracy by forming a tapered portion, that is reduced in diameter toward the leeward, in a suction duct, and by installing a light emitting element and a light receiving element at around the leeward end of the tapered portion in the suction duct. CONSTITUTION:A suction duct 7 is formed into a body together with a handle 8, its windward side is attached with a floor nozzle by an extension pipe, and its leeward is connected to a suction chamber of a vacuum cleaner by a hose. A tapered portion 9 that is reduced in diameter toward the leeward is formed in a portion of the suction duct 7. A light emitting element 3 and a light receiving element 4 are arranged face-to-face at around the end 9a of the tapered portion 9, and they face the inside of the suction duct with transparent covers 5. A detector 6 detects an amount of dust according to the received light detected by the light receiving element 4, and regulates a fan motor to perform the suction control. On the leeward beyond the end 9a of the tapered portion 9, air current flows along the inner surface of the duct 7, and dust swirls out toward the center of the duct 7 as shown by the arrow G, so that dust can be prevented from adhering to the transparent cover 5.
