본 고안은 고속으로 회전되는 원심팬이 공기저항에 의해 변형되거나 파손되는 것을 방지하도록 하는 진공청소기용 원심팬에 관한 것이다.The present invention relates to a centrifugal fan for vacuum cleaners to prevent the centrifugal fan rotated at high speed to be deformed or damaged by air resistance.
종래의 진공청소기용 윈심팬은 제1도와 제2도에 도시되는 바와같이, 원추형의 중심부에 공기흡입구멍(21)으로부터 나선상으로 상부체결구멍(22)이 형성된 상판(20)과, 이 상판(20)의 상부체결구멍(22)과 대응되는 하부체결구멍(31)이 형성되며 모터축(미도시)에 체결되는 하판(30)과, 이 상,하판(20,30)이 일정한 간격을 유지하도록 하고 상부체결구멍(22)과 하부체결구멍(31)에 체결되는 상,하부체결돌기(41,42)가 각각 돌출되는 베인(40)들로 구성되었다.As shown in FIG. 1 and FIG. 2, a conventional vacuum cleaner winssimb fan has an upper plate 20 having an upper fastening hole 22 formed spirally from an air suction hole 21 at a central portion of a conical shape, and the upper plate ( The lower fastening hole 31 corresponding to the upper fastening hole 22 of the 20 is formed and the lower plate 30 fastened to the motor shaft (not shown), and the upper and lower plates 20 and 30 maintain a constant interval. The upper and lower fastening protrusions 41 and 42 fastened to the upper fastening hole 22 and the lower fastening hole 31 are composed of vanes 40 protruding, respectively.
이러한 종래의 진공청소기용 원심팬은, 상판(20)에 형성된 상부체결구멍(22)에 베인(40)의 상부체결돌기(41)를 체결하여 코킹(caulking)하였고, 이 베인(40)의 하부체결돌기(42)는 하판(20)에 형성된 하부체결구멍(31)에 체결하여 코킹(caulking)하였다.In the conventional vacuum centrifugal fan, the upper fastening protrusion 41 of the vane 40 is caulked by caulking to the upper fastening hole 22 formed in the upper plate 20, and the lower part of the vane 40 The fastening protrusion 42 was caulked by fastening to the lower fastening hole 31 formed in the lower plate 20.
이와같은 종래의 진공청소기용 원심팬은 제1도와 제2도에 도시되는 바와같이, 모터축의 회전에 따라 외부로부터 외부공기가 상판(20)의 공기흡입구멍(21)으로 흡입되었고, 이 공기흡입구멍(21)으로 흡입된 공기는 베인(40)들을 통과하여 배출되었다.In the conventional vacuum cleaner centrifugal fan, as shown in FIG. 1 and FIG. 2, external air is sucked from the outside into the air suction hole 21 of the upper plate 20 as the motor shaft rotates. Air sucked into the hole 21 was discharged through the vanes 40.
그러나, 이러한 종래의 진공청소기용 원심팬은, 고속으로 회전하는 원심팬이 공기저항에 의해 변형되거나 파손되었다. 즉, 원심팬의 회전에 의한 원심력과 베인들 사이의 공기회전에 의해 생기는 고기압력이 코킹부분에 집중되었기 때문에, 상기 베인이 변형되거나 파손되는 문제점이 있었다.However, in the conventional vacuum cleaner centrifugal fan, the centrifugal fan rotating at high speed is deformed or damaged by air resistance. That is, since the high pressure generated by the centrifugal force due to the rotation of the centrifugal fan and the air rotation between the vanes is concentrated in the caulking portion, there is a problem that the vanes are deformed or broken.
본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 고속으로 회전되는 원심팬이 공기저항에 의해 변형되거나 파손되는 것을 방지하기 위한 진공청소기용 원심팬을 제공하는 데있다.An object of the present invention is to solve the conventional problems as described above, to provide a centrifugal fan for vacuum cleaner to prevent the centrifugal fan rotated at high speed to be deformed or damaged by air resistance.
이하 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.
본 고안 진공청소기용 원심팬은 제3도와 제4도에 도시되는 바와같이, 원추형의 중심부에 형성되는 공기흡입구멍(201)으로 부터 나선상으로 상부체결홈부(202)가 돌출되도록 형성되는 상판(200)과, 이 상판(200)의 상부체결홈부(202)와 대응되도록 하는 하부체결홈부(301)가 돌출되도록 형성되며 모터축(미도시)과 체결되는 하판(300)과, 이 상판(200)과 하판(300)이 일정한 간격을 유지하도록 체결되고 상판(200)의 상부체결홈부(202)와 아판(300)의 하부체결홈부(301)에 체결되도록 형성되는 베인(400)들로 구성함을 그 기술적 구성상의 특징으로 한다.The centrifugal fan for the vacuum cleaner of the present invention has a top plate 200 formed so as to protrude the upper fastening groove 202 spirally from the air suction hole 201 formed in the center of the conical shape as shown in FIGS. 3 and 4. And a lower plate 300 formed to protrude from the upper fastening groove 202 of the upper plate 200 and protruding with a motor shaft (not shown), and the upper plate 200. And the lower plate 300 is fastened to maintain a constant interval and consists of vanes 400 formed to be fastened to the upper fastening groove 202 of the upper plate 200 and the lower fastening groove 301 of the apan 300 The technical configuration features.
이러한 본 고안 진공청소기용 원심팬은 제3도와 제4도에 도시되는 바와 같이, 상판(200)의 상부체결홈부(202)와 하판(300)의 하부체결홈부(301)에 베인(400)을 체결하여 코킹하도록 한다.The centrifugal fan for the vacuum cleaner of the present invention has a vane 400 in the upper fastening groove 202 of the upper plate 200 and the lower fastening groove 301 of the lower plate 300, as shown in FIG. 3 and FIG. 4. Tighten and caulk.
한편, 본 고안 진공청소기용 원심팬은 제3도와 제4도에 도시되는 바와같이, 모터축(미도시)의 회전에 따라 외부로부터 외부공기가 상판(200)의 공기흡입구멍(201)으로 흡입되고, 이 공기흡입구멍(201)으로 흡입된 공기는 베인(400)들을 통과하여 배출된다.On the other hand, the centrifugal fan for the vacuum cleaner of the present invention, as shown in FIG. The air sucked into the air suction hole 201 is discharged through the vanes 400.
이상에서 살펴 본 바와같이, 본 고안 진공청소기용 원심팬은, 종래 원심팬의 회전에 의한 원심력과 베인에 의한 공기압력이 코킹부분에 집중되었던 것을, 상판과 하판에 각각 상,하부체결홈부를 형성하고, 상기 상,하부체결홈부에 베인을 체결함으로써, 내부에서 발생되는 공기압력을 상판과 하판에 형성된 상,하부체결홈부들에 고르게 분산시켜 주고, 이로 인하여 베인이 변형되는 것과 파손되는 것을 방지하여 주는 유용한 것이다.As described above, in the vacuum cleaner centrifugal fan of the present invention, the centrifugal force due to the rotation of the centrifugal fan and the air pressure due to the vanes are concentrated on the caulking portion, and the upper and lower fastening grooves are formed on the upper and lower plates, respectively. By fastening the vanes to the upper and lower fastening grooves, the air pressure generated therein is evenly distributed to the upper and lower fastening grooves formed on the upper and lower plates, thereby preventing the vanes from being deformed and damaged. Notes are useful.
