Description

진공청소기의 전동기 장착구조Motor mounting structure of vacuum cleaner

본 발명은 진공청소기에 관한 것으로서, 특히 고정자와 회전자로 대별하고 전류의 인가에 따라 회전자가 회전하여 흡인(suction)을 발생하는 전동기의 진동을 제어하는 진공청소기용 전동기의 창착구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a mounting structure of a vacuum cleaner electric motor that controls vibrations of an electric motor in which a stator and a rotor are separated and the rotor rotates in response to the application of an electric current to generate suction.

일반적으로 진공청소기는 전동기의 회전축에 장착한 임펠러를 고속으로 시키면 청소기 내부의 공기는 몸체 밖으로 배출되어 몸체 내부의 기압이 대기압보다 낮게 된다. 이에 몸체 내부에 흡입력이 발생되어 청소대상면의 공기는 이물질과 함께 청소기 내부로 빨려 들어가 이물질은 집진봉지에 모아 제거되고 정화된 공기는 대기중으로 배출됨으로써, 청소를 행하게 된다. 따라서 진공청소기의 집진정도는 전동기의 성능, 즉 임펠러의 회전수에 비례하여 향상된다.In general, when a vacuum cleaner makes the impeller mounted on the rotating shaft of the motor at high speed, the air inside the cleaner is discharged out of the body, and the air pressure inside the body is lower than atmospheric pressure. The suction force is generated in the body so that the air on the object to be cleaned is sucked into the cleaner together with the foreign matter, and the foreign matter is collected in the dust collecting bag, and the purified air is discharged into the atmosphere, thereby cleaning. Therefore, the degree of dust collection of the vacuum cleaner is improved in proportion to the performance of the motor, that is, the rotational speed of the impeller.

그러나 전동기는 구동시 임펠러의 회전수에 비례하여 각종 마찰저항이 증대되어 전동기의 성능 저하 및 진공청소기의 신뢰감을 저하시킨다. 이에 저소음, 저진동의 전동기를 실현함은 진공청소기에 있어 중요한 관점이 된다.However, when the motor is driven, various frictional resistances increase in proportion to the rotational speed of the impeller, thereby degrading the performance of the motor and reducing the reliability of the vacuum cleaner. Therefore, the realization of a low noise and low vibration motor is an important aspect of the vacuum cleaner.

제1도에서 종래 기술에 의한 진공청소기용 전동기(40)는 배기로를 이루는 하우징(42) 내부에 고정자 및 회전자를 내장하고, 하우징(42) 외부로 소정범위 돌출한 회전자의 회전축(48)단에 임펠러(4)를 장착한 후 흡입공(46)을 형성한 임펠러커버(44)를 덮는 구성으로, 상기 임펠러커버(44) 외경 및 하우징(42) 단부 외경에 패킹(6)(8)을 끼워 몸체(10)의 구동실(14)에 장착하였다.In FIG. 1, the vacuum cleaner electric motor 40 according to the related art includes a stator and a rotor inside a housing 42 constituting an exhaust path, and a rotating shaft 48 of the rotor protruding a predetermined range out of the housing 42. After mounting the impeller (4) at the end to cover the impeller cover 44 formed the suction hole 46, the packing (6) (8) to the outer diameter of the impeller cover 44 and the outer diameter of the housing 42 end ) Was mounted on the drive chamber 14 of the body 10.

그러나 상기한 종래의 진공청소기용 전동기(40)는 임펠러커버(44)에 끼워진 패킹(6)이 단일 구조로 전동기(14) 저면에 밀착되고, 아울러 임펠러커버(44)에 끼워진 패킹(6)이 임펠러(4)의 둘레면과 인접한, 즉 전동기(40)에서 가장 큰 진동음을 일으키는 부위에 끼워짐으로써 전동기(40)의 소음 및 진동을 감쇄, 외부와 차단하게는 구조적으로 문제가 있었다.However, in the conventional vacuum cleaner motor 40, the packing 6 fitted to the impeller cover 44 is in close contact with the bottom surface of the motor 14 in a single structure, and the packing 6 fitted to the impeller cover 44 is provided. There is a structural problem to attenuate the noise and vibration of the electric motor 40 and to block it from the outside by being fitted adjacent to the circumferential surface of the impeller 4, that is, the site generating the largest vibration sound in the electric motor 40.

본 발명은 상기한 문제점을 해결하기 위하여 창출한 것으로서, 본 발명의 목적은 임펠러를 포함한 전동기에서 비교적 진동이 작은 임펠러가 내장된 임펠러커버의 흡입공에 인접하여 끼워지는 패킹을 복수개의 완충부재로 지지하여 전동기의 진동음이 완충부재에 의해 다단식으로 감소하는 진공청소기의 전동기 장착구조를 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention is to support a packing that is fitted adjacent to the suction hole of the impeller cover with a built-in relatively small vibration in the electric motor including the impeller with a plurality of buffer members Therefore, to provide an electric motor mounting structure of the vacuum cleaner in which the vibration sound of the electric motor is reduced in multiple stages by the buffer member.

The first packing 70 applied to the present invention is a vibration sound of the electric motor 40. It fits in the outer diameter adjacent the suction hole 444 of the impeller cover 44 with the smallest vibration sound with respect to the circumferential surface of the largest impeller cover 44.

상기 전동기(40)의 흡입공(444)과 인접하여 임펠러커버(44)의 외경을 지지하는 제1패킹(70)과, 제1패킹(70)을 지지하는 방진부재(100)와, 제1지지대(50)를 지지하는 방진부재(100)(110)는 면접촉하는 상대물과의 대응면 또는 대응되는 타면중 어느 일면에 요철부(120)를 형성하여 구성한다.A first packing 70 supporting the outer diameter of the impeller cover 44 adjacent to the suction hole 444 of the electric motor 40, a dustproof member 100 supporting the first packing 70, and a first The anti-vibration members 100 and 110 supporting the support 50 are formed by forming the uneven portion 120 on any one surface of the corresponding surface or the other surface corresponding to the counterpart in contact with the surface.

우선 통상의 작동 방식에 의해 전동기(40)가 작동되도록 외부공기와 임펠러(4)간의 유속마찰음 및 회전마찰에 의해 전동기(40)에 진동이 발생한다.First, vibration is generated in the motor 40 by the speed friction sound and the rotational friction between the external air and the impeller 4 so that the electric motor 40 is operated by a normal operation method.
