Abstract

PURPOSE: To promote the efficiency of a runner by adopting a diffuser with an outside diameter 1.8W3.0 times a wide as that of a runner and a guide blade with an inlet angle of 5W10°.
CONSTITUTION: The ratio of the inside diameter D1 to the outside diameter D2 in a runner 11 is selected to 0.31W0.40, the ratio of the peripheral width b2 of the runner to the outside diameter D2 of the runner to 0.030W0.060, the runner inlet angle α1 to 10W45°, the runner outlet angle α2 to 10W30°, the number blade to 6W11, and the ratio of the inside cross-sectional area to the outside cross-sectional area of the runner D1b1/D2b2 to 0.75W1.21. On the periphery of the centrifugal runner for a cleaner, air routes are arranged to surround this runner from the upper and lower sides. The outside diameter D4 of a diffuser is selected to be 1.8W3.0 times as wide as the outside diameter D2 of the runner.
