본 고안은 진공청소기용 정류자 전동기의 구조에 관한 것으로 특히, 하우징과 하우징커버의 체결구조를 개량하여 전동기의 크기를 소형화 할 수 있게 하는 정류자전동기의 하우징커버체결구조에 관한 것이다.The present invention relates to a structure of a commutator motor for a vacuum cleaner, and more particularly, to a housing cover fastening structure of a commutator motor that can reduce the size of the motor by improving the fastening structure of the housing and the housing cover.

진공청소기에 사용되는 정류자 전동기는 흡입체로부터 강한 진공흡입력이 발생하도록 본체에 내장되는 것으로, 그러한 정류자 전동기는 제1도에서와 같이 하우징(1)의 내부에 스테이터(2)가 압입되고 그 내경에 아마튜어(3)를 삽입시킨 후 그 상, 하측에 베어링을 지지할 수 있도록 한 하우징커버(4)가 결합되는 것이며, 상기 하우징커버(4)의 상부에는 가이드베인(5)이 스크류(46)에 의해 체결되고 그 상부에 부싱(6)과 와셔(7)가 안착되어 너트(6a)로 임펠러(8)를 고정시키게 되고, 이렇게 고정된 임펠러(8)의 상부에는 커버(9)가 복개된 후 전원이 공급되도록 상기 하우징(1)의 소정위치에 홀더(10)가 구성된다.The commutator motor used in the vacuum cleaner is built in the main body to generate a strong vacuum suction input from the suction body, and such commutator motor has a stator 2 press-fitted into the housing 1 as shown in FIG. After inserting the armature (3), the housing cover (4) is coupled to support the bearing on the upper, lower side, the guide vane (5) on the upper portion of the housing cover (4) screw 46 And the bushing 6 and the washer 7 are seated on the upper part to fix the impeller 8 with the nut 6a, and the cover 9 is covered on the upper part of the fixed impeller 8. The holder 10 is configured at a predetermined position of the housing 1 to supply power afterwards.

여기서 미설명 부호 5a는 하우징과 커버를 체결하는 스크류고, 13은 스핀들이다.Here, reference numeral 5a is a screw for fastening the housing and the cover, and 13 is a spindle.

이러한 전동기에 있어 종래에는 하우징(1)에 하우징커버(4)가 결합될 때 제2도와 제3도 및 제4도에서와 같이 하우징(1)과 하우징커버(4)에 소정폭의 평활면(C, C′)이 형성되어 수평유지 및 스크류 체결이 가능하도록 구성되어지는 것이다.In such a motor, when the housing cover 4 is coupled to the housing 1, a smooth surface having a predetermined width in the housing 1 and the housing cover 4 as shown in FIGS. 2, 3, and 4, respectively. C, C ') is formed to be configured to enable horizontal maintenance and screw fastening.

그런데 상기에서와 같이 결합 구성된 종래의 정류자 전동기에 있어 하우징커버(4)는 중앙베어링삽입구(41)의 외주연에 다수의 체결공(43)(47)을 구비하여 등간격 4곳에 평활면을 형성하고 스테이터(2)의 상측 계자코일(21)과 서로 접촉되지 않도록 일정한 절연공간을 유지하기 위해서는 스테이터(2)의 압입깊이를 하우징(1)의 윗면보다 낮게 압입시켜야 하므로써 하우징의 길이가 길어지게 되어 제품의 부피가 커지고, 하우징 커버와 하우징의 평활면(C, C′)을 겹치도록 하므로써 재료의 소모가 증대되는 결함이 있었다.However, in the conventional commutator motor configured as described above, the housing cover 4 is provided with a plurality of fastening holes 43 and 47 at the outer circumference of the central bearing insertion hole 41 to form smooth surfaces at four equal intervals. In order to maintain a constant insulating space so that the upper field coil 21 of the stator 2 does not contact each other, the press-in depth of the stator 2 must be press-fitted lower than the upper surface of the housing 1 so that the length of the housing becomes long. There is a defect in that the volume of the product is increased and the consumption of the material is increased by making the housing cover and the smooth surfaces C and C 'of the housing overlap.

이에 본 고안은 상술한 바와같은 종래의 제반 결합을 감안하여 이루어진 것으로, 그 목적은 전동기의 크기를 소형화 할 수 있게함과 아울러 제조원가를 절감할 수 있게 하는 정류자전동기를 제공함에 있다.The present invention is made in view of the conventional combination as described above, the object is to provide a commutator motor that can reduce the size of the electric motor and reduce the manufacturing cost.

이러한 본 고안의 목적은 하우징커버의 구조를 개량시킨 정류자 전동기의 구조를 제공함에 의해 달성되는데, 이는 스크류체결구와 벤딩부 및 엠보싱부를 갖춘 하우징커버를 갖추어 하우징에 압입되는 스테이터의 상측계자코일과 간섭되지 않도록 하우징에 삽입되어 밴딩에 의해 고정설치되어 이루어지는 것이다.The object of the present invention is achieved by providing a structure of a commutator motor with an improved structure of the housing cover, which is provided with a housing cover with a screw fastening part and a bending part and an embossing part so as not to interfere with the upper field coil of the stator pressed into the housing. Is inserted into the housing so as to be fixed by banding.

이하, 첨부된 도면에 의거하여 본 고안 일실시예의 구성을 상세히 설명한다.Hereinafter, on the basis of the accompanying drawings will be described in detail the configuration of an embodiment of the present invention.

제1도는 일반적인 정류자 전동기의 반단면도로써 이는 하우징(1)의 내부에 스테이터(2)가 압입되고 그 내경에 아마튜어(3)를 삽입시킨후 그 상, 하측에 베어링을 지지하는 하우징커버(4)가 결합되는 것이며, 상기 하우징커버(4) 상부에는 가이드베인(5)과 임펠러(8)가 고정되고, 임펠러(8)의 상부에는 커버(9)가 복개되어 이루어진다.FIG. 1 is a half sectional view of a general commutator motor, in which a stator 2 is press-fitted into a housing 1 and a housing cover 4 supporting a bearing on the upper and lower sides after inserting an armature 3 into an inner diameter thereof. ) Is coupled, the guide vane 5 and the impeller 8 is fixed to the upper portion of the housing cover 4, the cover 9 is made of the upper cover of the impeller (8).

이러한 일반적인 정류자전동기의 구조에 있어 본 고안 하우징커버(40)는 제5도에서와 같이 장방형 몸체의 중앙을 수평상태로 하고 양측을 소정각도로 경사를 이루게 하며 단부를 수평으로 연장시키는 것이며, 중앙에 베어링삽입구(41)를 형성하고 양단의 네 모서리에 스크류체결공(42)를 통공시킨다.The housing cover 40 of the present invention in the structure of such a general rectifier motor is to make the center of the rectangular body in a horizontal state, inclined both sides at a predetermined angle and extend the end horizontally, as shown in FIG. A bearing insertion hole 41 is formed, and screw fastening holes 42 are formed through four corners of both ends.

또한 상기 베어링삽입구(41) 중심의 양측에 가이드베인 체결공(43)을 통공시키고 양단이 전후방이 엇갈리게 엠보싱돌기(44)를 형성시키며 양측 네모서리 단부에 하향으로 직각으로 절곡되는 벤딩편(45)을 구성시키게 된다.In addition, through the guide vane fastening hole (43) through both sides of the center of the bearing insertion hole (41) to form an embossing projection (44) with both ends staggered forward and backward bending the bending piece 45 at a right angle downwards at both ends of the corners. Will be configured.

그리고 상기 하우징커버(40)가 결합되는 하우징(1)의 상면에는 상기 스크류체결공(42)가 엠보싱돌기(44) 및 밴딩편(45)과 대응하는 양측에 스크류체결공(11)과 안내홈(12) 및 지지홈(13)을 각각 통공시키게 되는 것이다.In addition, the screw fastening hole 42 is provided at both sides of the screw fastening hole 42 and the bending piece 45 at the upper surface of the housing 1 to which the housing cover 40 is coupled. 12 and the support groove 13 is to pass through each.

이상에서와 같이 결합구성된 본 고안의 결합과정과 작용효과를 제6, 7도를 참조하여 상세히 설명한다.As described above, the coupling process and the effect of the present invention constituted as described above will be described in detail with reference to FIGS. 6 and 7.

먼저, 스테이터(2)와 아마튜어(3)가 내장된 하우징(1)의 상부에 본 고안 하우징커버(40)를 안착시키게 되는데, 이때, 하우징커버(40)는 스테이터(2)의 상측계자 코일(21)과 간섭되지 않도록 계자코일(21)의 좌, 우측 중앙과 안착되게 일치시킨후 그 양측단에 형성된 스크류 체결공(42)과 엠보싱돌기(44) 및 밴딩편(45)을 하우징(1)의 상면에 형성된 스크류체결공(11)과 안내홈(12) 및 지지홈(13)에 각각 삽입시킨다.First, the housing cover 40 of the present invention is seated on the upper part of the housing 1 in which the stator 2 and the armature 3 are embedded. In this case, the housing cover 40 is the upper field coil of the stator 2. The screw fastening hole 42, the embossing protrusion 44, and the bending piece 45 formed on both side ends of the field coil 21 to be seated coincide with the left and right centers of the field coil 21 so as not to interfere with the housing 21. Inserted into the screw fastening hole 11 and the guide groove 12 and the support groove 13 formed on the upper surface of the).

이와같이 하우징(1)의 상면에 하우징커버(40)가 안착되면 상기 스크류체결공(42)에 스크류를 체결하고, 지지홈(13)에 삽입된 밴딩편(45)을 일측으로 밴딩시켜 하우징커버(40)를 하우징(1)에 완전히 결합시키게 되는 것이며, 이어서 가이드베인(5)과 임펠러(8)등은 통상에서와 같은 과정을 통하여 상기와 같이 하우징(1)의 상면에 결합된 하우징커버(40)의 상부에 고정시키게 되는 것이다.As such, when the housing cover 40 is seated on the upper surface of the housing 1, the screw is fastened to the screw fastening hole 42, and the bending piece 45 inserted into the support groove 13 is bent to one side to cover the housing cover ( 40 is to be completely coupled to the housing (1), and then the guide vane (5) and the impeller (8), the housing cover (40) coupled to the upper surface of the housing (1) as described above through the same process as usual It will be fixed on top of).

따라서 본 고안은 하우징과 하우징커버의 구조를 간소하게 개량하므로써 전동기의 크기를 소형화 할 수 있게 함은 물론 제조원가를 절감할 수 있는 유용한 고안인 것이다.Therefore, the present invention is a useful design that can reduce the manufacturing cost as well as to reduce the size of the motor by simply improving the structure of the housing and the housing cover.
