본 고안은 건·습식 진공청소기용 전동기에 관한 것으로서, 특히 전동기에 장착된 냉각장치의 위치 및 구조를 변형시켜 부품감소에 따른 소형경량화 및 원가절감과 조립성이 향상되는 건·습식 진공청소기용 전동기에 관한 것이다.The present invention relates to an electric motor for a dry and wet vacuum cleaner, and in particular, a motor for a dry and wet vacuum cleaner which improves compact weight, cost reduction, and assembly by reducing the location and structure of the cooling device mounted on the motor. It is about.

일반적으로 건·습식 진공청소기용 전동기는 건식 진공청소기용 전동기와는 달리 임펠러의 회전에 의해 임펠러카바의 흡입구로 흡입된 공기가 고정자 및 회전자측으로 통과됨이 없이 임펠러카바의 배출구로 배출됨으로써 고정자 및 회전자측에서 발생된 열을 방열·냉각시키기 위하여 냉각장치로서 냉각팬이 별도로 장착되는 것이다.In general, the electric motor for dry and wet vacuum cleaners is different from the electric motors for dry vacuum cleaners, so that the air sucked into the inlet of the impeller cover by the rotation of the impeller is discharged to the outlet of the impeller cover without passing through the stator and the rotor side. In order to radiate and cool the heat generated on the rotor side, a cooling fan is separately installed as a cooling device.

제1도는 종래의 건·습식 진공청소기용 전동기의 구성을 나타내는 단면도이다.1 is a cross-sectional view showing the configuration of a conventional dry / wet vacuum cleaner electric motor.

제1도를 참조하면 종래의 건·습식 진공성소기용 전동기는 고정자(7)내부에 삽입되는 도시되지 않은 회전자에는 회전자축(1)이 압입되에 회전자의 상·하측의 회전자축(1)은 각각 상. 하측 베어링(6), (6a)에 의해 지지되고, 회전자축(1)의 상단부는 냉각장치인 냉각팬(4)이 압입장착되어 냉각팬카바(5)에 의해 보호되며, 회전자축(1)의 하단부는 임펠러(2)가 압입장착 되어 흡입구 및 배출구(3a)가 형성된 임펠로카바(3)에 의해 보호되는 것이다.Referring to FIG. 1, a conventional dry / wet vacuum firing motor has a rotor shaft (1) press-fitted to a rotor (not shown) inserted into the stator (7), so that the rotor shafts (1) of the rotor (1) ) Each award. Supported by the lower bearings 6 and 6a, the upper end of the rotor shaft 1 is press-fitted by a cooling fan 4, which is a cooling device, and protected by the cooling fan cover 5, and the rotor shaft 1 The lower end of the impeller (2) is press-mounted is protected by the impeller cover (3) formed inlet and outlet (3a).

상기 하측베어링(6a)과 도시되지않은 회전자 사이의 회전자축(1)에는 절연부성(9) 및 하측베어링(6a)의 이탈방지를 위하여 멈춤링(8)이 개재장착된 것이다.In the rotor shaft 1 between the lower bearing 6a and the rotor (not shown), a stop ring 8 is interposed between the lower bearing 6a and the lower bearing 6a to prevent separation of the insulating portion 9 and the lower bearing 6a.

이와같이 구성된 종래의 건·습식 진공청소기용 전동기는 회전자축(1)의 구동에 의해 회전자축(1) 하단부에 장착된 임펠러(2)가 회전함과 동시에 회전자축(1) 상단부에 장착된 냉각팬(4)이 회전하게 되는 것이다.The conventional dry / wet vacuum cleaner electric motor configured as described above is a cooling fan mounted at the upper end of the rotor shaft 1 while the impeller 2 mounted at the lower end of the rotor shaft 1 is rotated by the driving of the rotor shaft 1. (4) will be rotated.

이때, 임폘러(2) 회전에 의해 흡입되는 공기는 이물질 흡입 제거에 사용된 것이며, 냉각팬(4)에 의해 흡입된 공기는 회전자 및 고정자(7)등의 전동기 내부에서 발생된 열을 방열·냉각시키는 것이다.At this time, the air sucked by rotating the impeller 2 is used to remove and remove foreign substances, and the air sucked by the cooling fan 4 dissipates heat generated inside the motor such as the rotor and the stator 7. · To cool.

그러나, 전동기 내부의 냉각창지인 냉각팬(4)은 상측 베어링(6)이 장착되어 전동기 내부를 이루는 프레임(110)상측으로 일정범위 돌출된 회전자축(1)의 상단부에 장착되며, 또한 냉각팬(4)의 보호를 위하여 냉각팬카바(5)가 장착됨으로써 전동기의 부피가 커지며, 다수의 부품사용에 따른 제품의 원가상승 및 생산성이 저하되는 문제점이 있었다.However, the cooling fan 4, which is a cooling window inside the motor, is mounted on the upper end of the rotor shaft 1 protruding a certain range onto the frame 110 forming the inside of the motor by mounting the upper bearing 6. The cooling fan cover 5 is installed for the protection of (4), the volume of the motor is increased, and there is a problem in that the cost and productivity of the product are reduced due to the use of a plurality of parts.

따라서 본 고안은 상기한 종래기술의 제반문제점들을 해결하기 위하여 안출한 것으로서, 본 고안의 목적은 전동기에 장착된 냉각장치의 위치 및 구조를 변형시켜 부품감소에 따른 소형화 및 경량화와 원가절감 및 조립성이 향상되는 건·습식 진공성소기용 전동기를 제공하는데 있다.Therefore, the present invention has been made to solve the above-mentioned problems of the prior art, the object of the present invention is to change the location and structure of the cooling device mounted on the electric motor to reduce the size and weight, cost reduction and assembly according to the reduced parts It is an object of the present invention to provide an improved motor for dry and wet vacuum burners.

이와같은 목적을 실현하기 위한 본 고안에 따른 건·습식 진공청소기용 전동기는 하단부로 부터 임펠러, 베어링, 절연부싱 및 회전자가 순차 압입장착되는 회전자축과, 상기 베어링과 절연부싱 사이에 개재장착되는 상면에 복수개의 블레이드가 형성된 냉각팬이 포함되는 것을 특징으로 한다.The motor for a dry / wet vacuum cleaner according to the present invention for achieving the above object is a rotor shaft in which an impeller, a bearing, an insulating bushing, and a rotor are sequentially press-fitted from the lower end, and an upper surface interposed between the bearing and the insulating bushing. It characterized in that it comprises a cooling fan is formed with a plurality of blades.

이하, 첨부된 도면 제3도와 제4도를 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 3 and 4.

도면중 부호 20은 회전자축(20)으로서, 상기 회전자축(20)은 하단부로부터 회전되어 이물질 제거수단으로서의 흡입력을 발생하는 임펠러(30)와, 앤드브라켓(60)에 압입장착된 베어링(50)과, 상측면에 복수개의 블레이드(100a)가 형성된 냉각팬(100)과, 상측으로 압입되는 회전자(70)의 권선(80)의 절연을 위하여 절연부싱(90)이 순차적으로 압입장착되는 것이다.Reference numeral 20 in the figure is a rotor shaft 20, the rotor shaft 20 is rotated from the lower end impeller 30 for generating a suction force as a foreign matter removal means, and the bearing 50 is press-fitted to the end bracket 60 In addition, the insulating bushing 90 is sequentially press-fitted to insulate the cooling fan 100 having the plurality of blades 100a formed on the upper side and the winding 80 of the rotor 70 press-fitted upward. .

상기의 냉각팬(100)은 회전자축(20)에 압입되도록 중앙에 축공(100b)이 형성되며, 축공(10Ob) 상·하측 주연부에는 링형상의 돌출부(10Oc)가 형성된 것으로서, 돌출부(100c)의 상측단이 절연부싱(90)에 밀착됨으로써 돌출부(100c)의 하측단이 베어링(50)을 지지하여 멈춤링 기능을 대신하는 것이다.The cooling fan 100 has a shaft hole (100b) is formed in the center so as to be pressed into the rotor shaft 20, the upper and lower peripheral portion of the shaft hole (10b) is formed with a ring-shaped protrusion (100c), the protrusion (100c) By the upper end of the close contact with the insulating bushing 90, the lower end of the protrusion 100c supports the bearing 50 to replace the stop ring function.

또한 임펠러(30)는 흡입구 및 배출구(40a)가 형성된 임펠러카바(40)에 의해 보호되는 것이다.In addition, the impeller 30 is protected by the impeller cover 40 formed with the inlet and outlet 40a.

따라서, 회전자축(20)에 의해 임펠러(30)가 회전함과 동시에 냉각팬(100)이 동시에 회전하여 공기를 흡입하며, 흡입된 공기는 냉각팬(100)의 상면에 장착된 복수개의 블레이드(1OOa)에 의해 와류되어 전동기 상부로 보내서 전동기의 열을 흡수·방열하여 전동기를 냉각시키게 되는 것이다.Therefore, the impeller 30 is rotated by the rotor shaft 20 and the cooling fan 100 rotates at the same time to suck in air, and the sucked air is provided with a plurality of blades mounted on the upper surface of the cooling fan 100. It is vortexed by 100a and sent to the upper part of the motor to absorb and dissipate heat of the motor to cool the motor.

이때, 냉각팬(100)의 전동기내의 저부에 위치함으로써 냉각팬(100)보호를 위한 냉각팬카바가 제거되는 것이다.At this time, the cooling fan cover for protecting the cooling fan 100 is removed by being located at the bottom of the electric motor of the cooling fan 100.

또한, 냉각팬(100)의 축공(100b) 상·하측 주연부에 링형상으로 돌출형성된 둘출부(100c)는 돌출부(100c) 상측단이 절연부싱(90) 단부에 밀착됨으로써 돌출부(100c) 하측단이 베어링(50)을 지지하게 되어 돌출부(100c)가 멈춤링기능을 대신하게 되는 것이다.In addition, the head portion 100c protruding in a ring shape on the upper and lower circumferential portions of the shaft hole 100b of the cooling fan 100 has the upper end of the protrusion 100c close to the end of the insulating bushing 90 so that the lower end of the protrusion 100c is close. The bearing 50 is supported so that the protrusion 100c replaces the stop ring function.

이에따라 냉각팬카바 제거에 부가하여 멈춤링을 제거함으로써 부품감소에 따른 제품의 소형·경량화와 원가절감 및 생산성이 향상되는 유용한 고안이다.Accordingly, by removing the stop ring in addition to removing the cooling fan cover, it is a useful design to reduce the size, weight, cost and productivity of the product according to the reduction of parts.
