ABSTRACT:
A vacuum cleaner is constructed of relatively rigid, molded plastic main structural elements including a direct collecting tank and a motor housing releaseably secured to each other by a buckle. The main structural plastic elements also include a fan housing wherein a centrifugal fan rotates, a mounting plate to which the motor is secured; and a baffle member having a cup formation which receives the rear of the motor. A common fastening means mechanically secures the fan housing, the plate, and the baffle members to the motor housing. A releaseable latch is at one end of the buckle and a hook at the other end thereof. The latch holds the tank and motor housing together, and the hook is for engaging a wall bracket to mount the cleaner in a vertical position. The buckle also includes a skid portion, located between the latch and hook, to facilitate movement of the cleaner along a horizontal supporting surface. Hundreds of relatively small apertures in the mounting plate are arranged in a narrow band adjacent the periphery of the fan so as to provide for the passage of air through the motor mounting plate without creating excessive back pressure while maintaining quiet conditions in spite of high speed air flow.
