본 고안은 진공청소기용 모터의 임펠러덮개에 관한 것으로 특히, 그 내벽에 흐르는 공기로 인해 발생되는 소음과 떨림을 줄여 주는 진공청소기의 임펠러덮개에 관한 것이다.The present invention relates to an impeller cover of a vacuum cleaner motor, and more particularly, to an impeller cover of a vacuum cleaner that reduces noise and vibration caused by air flowing in the inner wall thereof.

일반적으로 진공청소기의 본체는 제1도에서 보는 바와 같이, 전원에 의해 회전력을 발생시키는 모터(40), 모터 아마추어축(41)의 단부에서 장착되어 함께 회전되도록 된 임펠러(20), 임펠러와 모터 사이에 장착된 공기안내구(30) 및 모터몸체(42)과 연결되어 본체 하부몸체를 형성하는 임펠러덮개(10)로 구성되어 있다.In general, the main body of the vacuum cleaner, as shown in Figure 1, the motor 40 for generating a rotational force by the power source, the impeller 20, the impeller 20 and the motor mounted to be rotated together at the end of the motor armature shaft 41 It is composed of an impeller cover 10 connected to the air guide 30 and the motor body 42 mounted therebetween to form a lower body.

종래 진공청소기의 임펠러덮개(10)는 제2도에서 보는 바와 같이 원통부(13)와 원통 하단에서 안쪽으로 절곡 연장되어 바닥을 형성하는 하단부(15) 및 원통 상단에서 밖으로 약간 절곡 연장된 상단부(17)로 구성되고, 하단부(15) 바닥은 소정의 크기를 갖는 공기 흡입구(11)가 그 중심부에 뚫려 있다.As shown in FIG. 2, the impeller cover 10 of the conventional vacuum cleaner has a cylindrical portion 13 and a lower portion 15 which is bent inwardly from the bottom of the cylinder to form a bottom and an upper portion slightly bent outwardly from the top of the cylinder ( 17), and the bottom of the lower part 15 has an air inlet 11 having a predetermined size at its center.

이러한 임펠러덮개(10)는 그 상단부 연부가 모터몸체(42)에 압입되어 본체에 고정되도록 하였으며, 전원이 상기 진공청소기의 본체에 인가되면 모터의 아마추어는 임펠러(20)와 동시에 회전하게 되며, 이때 임펠러(20)의 회전은 공기를 흡입하는 흡입력을 발생시키며, 흡입된 공기는 임펠러덮개(10)의 내벽면에 직접 부딪힌 후 공기안내구(30)에 의해 유도되어 모터 후면부로 이송된다.The impeller cover 10 is the upper edge portion is pressed into the motor body 42 is fixed to the main body, when the power is applied to the main body of the vacuum cleaner, the armature of the motor is rotated at the same time with the impeller 20, at this time The rotation of the impeller 20 generates a suction force for sucking air, and the sucked air is directly hit by the inner wall surface of the impeller cover 10 and then guided by the air guide 30 to the motor rear portion.

이와 같이 구성되고 작동되는 종래의 진공청소기는 임펠러(20)에서 배출되는 높고 빠른 공기가 직접 임펠러덮개(10)의 내벽면에 부딪힘으로써, 공기마찰로 인한 소음과 임펠러덮개의 떨림이 발생하는 결함이 있었다.The conventional vacuum cleaner constructed and operated as described above has a defect in which high and rapid air discharged from the impeller 20 directly hits the inner wall surface of the impeller cover 10, causing noise and vibration of the impeller cover due to air friction. there was.

본 고안의 목적은 공기가 흡입되는 흡입경로에 절곡된 면으로된 방음홈을 형성시켜, 고속 고압으로 흡입되는 공기를 이완시켜, 공기의 흐름에 의해 발생하는 소음과 떨림을 줄여주는 진공청소기의 임펠러덮개를 제공하기 위함이다.The purpose of the present invention is to form a soundproof groove of the curved surface in the suction path in which the air is sucked, to relax the air sucked at high pressure and high pressure, to reduce the noise and vibration caused by the flow of air vacuum cleaner impeller To provide a cover.

이하 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.

본 고안에 따른 임펠러덮개는 제3도와 제4도에서 보는 바와 같이, 소정의 직경을 가지고 원통부(13), 원통부(13) 원주를 따라 상단에서 밖으로 절골되어 약간 연장된 상단부(17) 및 그 중심부에는 흡입구(11)가 뚫려져 있으며 원통부(13) 하단에서 안쪽으로 절곡 연장되어 바닥을 형성하는 하단부(15)가 일체로 구성되며, 하단부(15)가 원통의 원주를 따라 절곡 돌출된 방음홈(16)이 형성됨을 그 기술적 특징으로 한다.As shown in FIG. 3 and FIG. 4, the impeller cover according to the present invention has a predetermined diameter, and a cylindrical portion 13, a cylindrical portion 13, the upper end portion 17 which is slightly extended outward from the upper end along the circumference thereof. The inlet 11 is drilled in the center thereof, and the lower end 15 is formed integrally with the lower end 15, which is bent inwardly from the lower end of the cylindrical part 13 to form a bottom. It is characterized in that the soundproof groove 16 is formed.

상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안에 의해 임펠러덮개(10)도 그 상단부(17)가 모터(42)에 압입되어 본체에 고정되도록 설치된다. 또, 전원이 본 고안을 장착한 진공청소기의 본체에 인가되면 모터(40)의 아마추어는 임펠러(20)와 동시에 회전하게 되며, 이때 임펠러(20)의 회전은 공기를 흡입하고, 흡입된 공기는 임펠러덮개(10)의 바닥에 형성된 절곡면을 따라 공기안내구(30)쪽으로 흐르게 되고, 이어 모터 후면부로 이송된다. 이때, 공기의 압력과 속도는 절곡면으로 형성된 방음홈(16)에 의해 감소되어 소음과 진동이 저감되어진다.According to the present invention, the impeller cover 10 is also installed so that the upper end portion 17 is pressed into the motor 42 and fixed to the main body. In addition, when power is applied to the main body of the vacuum cleaner equipped with the subject innovation, the armature of the motor 40 rotates at the same time as the impeller 20, wherein the rotation of the impeller 20 sucks air, and the sucked air is Along the bent surface formed in the bottom of the impeller cover 10 is flowed toward the air guide 30, and then transferred to the motor rear portion. At this time, the pressure and speed of the air is reduced by the soundproof groove 16 formed as the bent surface, and noise and vibration are reduced.

이상에서 살펴본 바와 같이 본 고안은 진공청소기의 임펠러에서 배출되는 높은 압력의 빠른 공기가 절곡면으로된 방음홈에서 그 압력과 속도가 이완되게 함으로써, 흡입된 공기가 임펠러덮개의 내벽에 직접 부딪히며 발생시키는 떨림과 소음을 줄여주는 매우 유용한 것이다.As described above, the present invention allows the high pressure fast air discharged from the impeller of the vacuum cleaner to relax its pressure and speed in the curved soundproof groove, so that the sucked air is generated by hitting the inner wall of the impeller cover directly. It is very useful for reducing trembling and noise.
