发明名称 Upright type electric cleaner
摘要 An upright type electric cleaner including a main body case (1) and a suction port body (1), wherein when the main body case is brought to an upright position as the machine is inoperative, a rotary brush extending downwardly from the bottom of the suction port body (1) is released from contact with the surface to be cleaned. The suction port body includes a single switching knob which, when manipulated, enables the speed of operation of the rotary brush and the distance between the rotary brush and the surface to be cleaned to be adjusted simultaneously. A part of exhaust air of the cleaner released through a blower is led through a sound absorbing duct located in a bag compartment into a cord reel chamber to thereby greatly reduce the noise level of exhaust and preventing cord overheating of a power cord of the cleaner.
