The ratio R / b 1 of was set in the range of 0.6 to 0.9.
제조 비용 절감 및 소형 경량화를 도모하는 동시에, 전동 송풍기 효율 및 청소기의 흡입 일률을 향상시키는 전동 송풍기 및 전기 청소기를 제공한다.Provided are an electric blower and an electric vacuum cleaner that reduce manufacturing costs and reduce weight, and improve electric blower efficiency and vacuum suction efficiency.
전기 청소기의 흡입 풍량이 1.0m3/min이상인 영역에서 상기 전동 송풍기의 회전수를 40,000내지 50,000rpm으로 설정하였다.The rotation speed of the electric blower was set to 40,000 to 50,000 rpm in the region where the suction air flow rate of the vacuum cleaner was 1.0 m 3 / min or more.
또, 전동 송풍기의 원심 임펠러의 블레이드 중앙측의 선단 끼리를 잇는 가상 원환의 면적 S1과 상기 원심 임펠러의 입구 면적 S0의 비 S1/S0를 1.0 내지 1.4로 하고, 블레이드의 외주측 출구 폭 치수 b2와 외경 치수 D2의 비 b2/0.07 이상으로 하고, 블레이드의 내주측 유로 단면적(D1·b1)과 외주측 유로 단면적(D2·b2)의 비(D1·b1/D2·b2)를 0.74 이하로 하고, 블레이드의 입구 폭 치수 b1과 출구 폭 치수 b2의 비 b1/b2를 2.0이하로 하고, 입구부를 자오면으로 해서 본 때의 상기 라운딩의 곡률 반경 R과 블레이드 입구 폭 치수 b1의 비 R/b1를 0.6 내지 0.9의 범위로 설정하였다.In addition, the ratio S 1 / S 0 of the area S 1 of the virtual annular ring connecting the front ends of the blade center side of the centrifugal impeller of the electric blower and the inlet area S 0 of the centrifugal impeller is 1.0 to 1.4, and the outer peripheral side exit of the blade Ratio of width dimension b 2 to outer diameter dimension D 2 b 2 / Less than 0.07, and is the ratio (D 1 · b 1 / D 2 · b 2) of the inner flow passage area (D 1 · b 1) and the outer flow path cross-sectional area (D 2 · b 2) of the blade to less than 0.74 And the ratio of the radius of curvature R of the rounding to the blade inlet width dimension b 1 when the ratio b 1 / b 2 of the blade inlet width dimension b 1 and the outlet width dimension b 2 is 2.0 or less and the inlet portion is the inertia. R / b 1 was set in the range of 0.6 to 0.9.
