세탁기의 구동모터 냉각팬구조Drive motor cooling fan structure of washing machine

본 고안은 세탁기에 관한 것으로서, 더욱 상세하게는 세탁기의 구동모터에 설치되어 이를 냉각시켜 주는 세탁기의 구동모터 냉각팬구조에 관한 것이다.The present invention relates to a washing machine, and more particularly, to a drive motor cooling fan structure of a washing machine installed in the driving motor of the washing machine to cool it.

일반적으로 세탁기는 기히설정된 세탁행정 예컨데, 세탁수가 급수되는 급수행정과, 상기 급수행정을 거쳐 급수되어진 세탁수를 통하여 세탁물을 세탁하게 되는 세탁행정과, 상기 세탁행정을 거쳐 세정된 세탁물을 헹구는 헹굼행정과, 상기 헹굼행정을 거쳐 깨끗하게 세탁된 세탁물을 탈수하는 탈수행정으로 이루어지며, 상기한 일련의 세탁행정을 갖는 통상의 세탁기 구성은 제 1 도에 도시된 바와 같이 사각함체 형상의 캐비넷(10)과; 상기 캐비넷(10) 내부에 설치되는 저수조(20)와; 상기 저수조(20)내에 세탁물이 담겨지는 소정형상의 세탁조(30)와; 상기 캐비넷(10) 하부에 정역가능한 구동모터(41)와 밸트(미도시)로서 연결되어 세탁조(30)내의 펄세이터(42)를 회전시켜 주는 구동수단(40); 등으로 구성된다.In general, the washing machine is a washing stroke set in advance, for example, a water supply stroke for washing the wash water, a washing stroke for washing the laundry through the washing water supplied through the water supply stroke, and a rinsing stroke for rinsing the laundry washed through the washing stroke. It consists of a dehydration stroke to dehydrate the laundry washed cleanly through a rinsing stroke, the conventional washing machine configuration having a series of the washing stroke is a cabinet 10 of the rectangular box shape as shown in FIG. 1; A reservoir 20 installed in the cabinet 10; A laundry tub 30 having a predetermined shape in which laundry is contained in the water reservoir 20; A driving means (40) connected to a drive motor (41) and a belt (not shown) that can be reversed and reversed in the lower part of the cabinet (10) to rotate the pulsator (42) in the washing tank (30); And the like.

그리고, 상기 구동수단(40)의 구동모터(41)는 세탁공정 즉, 세탁행정과 탈수행정 중에 고속회전을 장시간 하기 때문에 과열이 되기 쉬우며, 이 과열을 미연에 방지하기 위하여 구동모터(41)와 일체로 회전되는 냉각팬(43)이 사용되며, 상기 냉각팬(43)의 구조를 보면, 제 2 도 도시된 것과 같이 소정 크기의 원판(43a)상의 중심선상에 구동모터(41)의 구동축(미도시)과 결합고정되는 고정축공(43b)이 형성되고, 이 고정축공(43b)에서 방사상으로 다수의 회전날개(43c)가 독립되게 형성설치된 것이다.In addition, the driving motor 41 of the driving means 40 is easily overheated because the high-speed rotation is performed for a long time during the washing process, that is, during the washing stroke and the dehydrating stroke, and in order to prevent the overheating, the driving motor 41 and The cooling fan 43 which is integrally rotated is used. Referring to the structure of the cooling fan 43, as shown in FIG. 2, the driving shaft of the driving motor 41 on the center line on the disc 43a of a predetermined size is shown. A fixed shaft hole (43b) is formed and coupled to the fixed shaft hole (43b), a plurality of rotary blades (43c) radially formed in the fixed shaft hole (43b) is installed independently.

그런데, 이와 같이 구성된 종래의 냉각팬(43)은 그 회전날개(43c)의 형상이 일직선이기 때문에 이와 동심축상에 위치한 구동모터(41)로 바람이 집중되지 못하고 풍향이 측방으로 산개되므로서 구동모터(41)의 냉각효율을 극히 저하시키는 문제점이 있었다.However, the conventional cooling fan 43 configured as described above has a straight line in the shape of the rotary blade 43c, so that the wind is not concentrated to the driving motor 41 located on the concentric shaft, and the wind direction is spread laterally. There was a problem of extremely lowering the cooling efficiency of (41).

따라서, 본 고안은 이러한 종래의 문제점을 감안하여 개발된 것으로서, 냉각팬에서 생성된 바람이 구동모터로 집중되게 회전날개의 구조를 개선하므로서, 구동모터의 냉각효율을 극대화시킨 세탁기의 구동모터 냉각팬구조를 제공함에 그 목적이 있다.Therefore, the present invention was developed in view of such a conventional problem, and the drive motor cooling fan of the washing machine maximizing the cooling efficiency of the drive motor by improving the structure of the rotary blades so that the wind generated in the cooling fan is concentrated to the drive motor. The purpose is to provide a structure.

상기 목적을 달성하기 위하여 본 고안은 상기 냉각팬의 원판상에 회전날개를 방사상으로 형성설치하되, 상기 회전날개의 끝부분을 원판의 원주선을 따라 일방향으로 절곡시켜서 된 특징이 있다.In order to achieve the above object, the present invention is characterized in that the rotating blades are radially formed on the disk of the cooling fan, and the ends of the blades are bent in one direction along the circumference of the disk.

또한, 본 고안은 상기 회전날개의 끝부분을 원판의 원주선을 따라 일방향으로 절곡시키되, 그 절곡각도를 45。내외가 되도록 한 특징이 있다.In addition, the present invention is characterized in that the end of the rotary blade is bent in one direction along the circumference of the disc, the bending angle of about 45 °.

이하에서는 본 고안의 바람직한 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 3 은 본 고안에 따른 냉각팬의 평면도이고, 도 4 는 본 고안에 따른 세탁기의 단면도이다.3 is a plan view of a cooling fan according to the present invention, Figure 4 is a cross-sectional view of a washing machine according to the present invention.

먼저, 사각함체 형상의 캐비넷(110)과; 상기 캐비넷(110) 내부에 설치되는 저수조(120)와; 상기 저수조(120)내에 세탁물이 담겨지는 소정형상의 세탁조(130)와; 상기 캐비넷(110) 하부에 정역가능한 구동모터(141)와 밸트(미도시)로서 연결되어 세탁조(130)내의 펄세이터(142)를 회전시켜 주는 구동수단(140); 등으로 구성된 세탁기(100)에 있어서, 상기 구동수단(140)의 구동모터(141)에 냉각팬(143)을 설치하되, 소정 크기의 원판(143a)상의 중심선상에 구동모터(141)의 구동축(144)과 결합고정되는 고정축공(143b)을 형성하고, 이 고정축공(143b)에서 방사상으로 다수의 회전날개(143c)를 독립되게 각각 형성설치하는 한편, 상기 회전날개(143c)의 끝부분을 원판(143a)의 원주선을 따라 일방향으로 절곡시킨다.First, the cabinet 110 of the rectangular box shape; A reservoir 120 installed in the cabinet 110; A laundry tub 130 having a predetermined shape in which laundry is contained in the reservoir 120; A driving means 140 connected to the lower and lower drive cabinet 141 and a belt (not shown) in the cabinet 110 to rotate the pulsator 142 in the washing tub 130; In the washing machine 100 configured as such, the cooling fan 143 is installed on the drive motor 141 of the drive means 140, but the drive shaft of the drive motor 141 is located on the center line on the disc 143a of a predetermined size. And forming a fixed shaft hole (143b) to be coupled and fixed to the (144), respectively, while forming a plurality of rotary blades (143c) independently from the fixed shaft hole (143b), while the end of the rotary blade (143c) Is bent in one direction along the circumference of the disc 143a.

이때, 상기 회전날개(143c)의 끝부분을 절곡시키되, 절곡각도를 회전날개(143c)로 부터 약 45。 정도가 되도록 절곡하여 냉각팬(143)으로 부터 생성된 바람이 구동모터(141)로 집중되게 함이 바람직하다.At this time, the end of the rotary blade 143c is bent, the bending angle is bent to about 45 degrees from the rotary blade 143c by the wind generated from the cooling fan 143 to the drive motor 141. It is desirable to concentrate.

즉, 상기 냉각팬(143)이 회전하게 되면 회전날개(143c)로 부터 발생한 바람이 회전날개(143c)의 끝부분을 따라 흐르다가 45。로 절곡된 끝부분에서 동심축선상에 있는 구동모터(141)로 집중적으로 유도되도록 한 것이다.That is, when the cooling fan 143 is rotated, the wind generated from the rotary blade 143c flows along the end of the rotary blade 143c, and the driving motor is located on the concentric axis at the end bent at 45 °. 141).

상기와 같이 구성된 냉각팬(143) 구조는 본고안의 일 실시예에 불과하며, 예컨대 회전날개(143c)의 형상은 앞서 설명한 본고안의 범위내에서 얼마든지 그 변형이 가능하다.The structure of the cooling fan 143 configured as described above is only one embodiment of the present disclosure, and the shape of the rotary blade 143c may be modified in any manner within the scope of the present disclosure described above.

상기한 구성을 토대로 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention based on the above configuration is as follows.

세탁공정 즉, 세탁행정과 탈수행정 중에 구동수단(140)의 구동모터(141)가 회전을 시작하면 이 구동모터(141)의 동심축선상에 설치된 냉각팬(143)이 함께 회전하게 되는데, 이때 상기 냉각팬(143)이 회전하게 되면 회전날개(143c)로 부터 발생한 바람이 회전날개(143c)의 끝부분을 따라 흐르다가 45。로 절곡된 회전날개(143c)의 끝부분에서 동심축선상에 있는 구동모터(141)로 집중적으로 방출되어 고속회전 중인 구동모터(141)를 냉각시키게 된다.When the driving motor 141 of the driving means 140 starts to rotate during the washing process, that is, during the washing stroke and the dehydrating stroke, the cooling fan 143 installed on the concentric axis of the driving motor 141 rotates together. When the cooling fan 143 is rotated, the wind generated from the rotary blade 143c flows along the end of the rotary blade 143c, and is located on the concentric axis line at the end of the rotary blade 143c bent at 45 °. It is concentrated to the driving motor 141 to cool the driving motor 141 is rotating at high speed.

이상에서와 같이 본 고안에 따르면 냉각팬(143)에서 생성된 바람이 구동모터(141)로 집중되게 회전날개(143c)의 구조를 개선하므로서, 구동모터(141)의 냉각효율을 극대화시킨 효과가 있다.As described above, according to the present invention, by improving the structure of the rotary blade 143c so that the wind generated in the cooling fan 143 is concentrated on the driving motor 141, the effect of maximizing the cooling efficiency of the driving motor 141 is achieved. have.
