본 고안은 밀폐형 전동압축기의 고정자 냉각장치에 관한 것으로, 특히 고정자의 온도가 높은 밀폐형 전동압축기에 적당하도록 한 것에 관한 것이다.The present invention relates to a stator cooling apparatus of a hermetic electric compressor, and more particularly, to a suitable type of hermetic electric compressor having a high temperature of the stator.
종래의 고정자 냉각장치는 제1도와 제2도에서와 같이 크랭크축(3)의 내면 오일통로(4) 상단부 끝단에 안내경사부(4a)를 형성하고 그위에 다수의 구멍(5)이 천공된 다공판(6)을 삽착한후, 상부에서 덮개판(7)을 보울트(8)로 체결시킨 것이다.In the conventional stator cooling apparatus, as shown in FIG. 1 and FIG. 2, a guide inclined portion 4a is formed at the end of the upper end of the inner surface oil passage 4 of the crankshaft 3, and a plurality of holes 5 are drilled thereon. After inserting the porous plate 6, the cover plate 7 is fastened to the bolt 8 from the top.
따라서 제3도에서와 같이 크랭크축(3)이 화살표 방향으로 회전하면 하부용기(9)에 고여있던 냉동유는 원심력에 의해 상승되어 일부는 압축기의 각 습동부로 급유되고 나머지는 크랭크축(3) 끝단까지 상승하게 된다. 이때, 크랭크축(3) 끝단으로 상승된 냉동유는 안내경사부(4)로 유도되면서 다공판(6)의 구멍(5)들을 통하여 크랭크축(3) 외부로 비산되어 고정자(1)를 냉각시키게 되며, 다공판(6)은 상부의 덮개판(7)이 보울트(8)로 체결되어 있기 때문에 원심력에 의한 상부 이탈을 방지하게 된다. 그러나, 크랭크축(3)의 내면 안내경사부(4)와 다공판(6)의 구멍(5)은 가공이 매우 어려우며, 이들을 덮개판(7)에 의해 보울트(8)로 체결하므로서 조립성이 불량하였다.Therefore, as shown in FIG. 3, when the crankshaft 3 rotates in the direction of the arrow, the refrigeration oil accumulated in the lower container 9 is lifted by the centrifugal force, part of which is supplied to each sliding part of the compressor, and the rest of the crankshaft (3). ) To the end. At this time, the refrigeration oil raised to the end of the crankshaft (3) is guided to the guide inclined portion (4) is scattered to the outside of the crankshaft (3) through the holes (5) of the porous plate (6) to cool the stator (1) Since the cover plate 7 of the upper plate 6 is fastened by the bolt 8, the porous plate 6 prevents the upper part from being separated by centrifugal force. However, the inner surface guide inclined portion 4 of the crankshaft 3 and the hole 5 of the porous plate 6 are very difficult to machine, and are assembled by fastening them to the bolt 8 by the cover plate 7. It was poor.
또한, 크랭크축(3)의 구멍(5)을 통해 외부로 비산되는 오일은 원심력이 약하기 때문에 비산력 역시 약해서 고정자(1)까지 확실한 전달이 안되고 회전자(2)로 낙하되어서 고정자(1)의 냉각효과가 저하되며, 그로인하여 압축기의 효율까지 크게 저하되는 등의 문제점이 있었다.In addition, since the oil scattered to the outside through the hole 5 of the crankshaft 3 has a weak centrifugal force, the scattering force is also weak, so that it is not transmitted to the stator 1 without any reliable transmission and falls to the rotor 2 so that the stator 1 There is a problem that the cooling effect is reduced, thereby greatly reducing the efficiency of the compressor.
때문에 본 고안은 이와같은 종래의 문제점을 해결하기 위하여 크랭크축 상단 끝단부에 다수의 돌출요홈을 형성하고 원형판으로 된 오일유도판(12)을 삽착시켜 상승 비산되는 오일을 안내하게 하여 오일을 고정자로 확실하게 전달하게 하므로서 고정자의 냉각효과를 증대시키게 한바, 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Therefore, the present invention forms a plurality of protruding grooves at the upper end of the crankshaft to solve the conventional problems, and inserts the oil guide plate 12 made of a circular plate to guide the oil which is rising and scattered to stator oil. In order to reliably transmit to increase the cooling effect of the stator, it will be described in detail by the accompanying drawings as follows.
크랭크축(3) 내면에 오일통로(4)를 가진 밀폐형 전동압축기에 있어서, 크랭크축(3) 상단부의 끝단 내면에는 안내경사부(10)를 형성하고 그 상단에 다수의 돌출요홈(11)를 형성하여서 오일 유도관(12)을 삽착시키되, 상부는 원판(13)으로되고 하부에는 다수의 오일 안내홈(14)을 가진 안내연결부(15)를 형성시켜서 된 것이다.In the hermetic electric compressor having an oil passage (4) on the inner surface of the crankshaft (3), a guide inclined portion (10) is formed on the inner surface of the end of the upper end of the crankshaft (3) and a plurality of protruding grooves (11) are formed on the upper end thereof. Forming and inserting the oil guide tube 12, the upper portion is to form a guide connection portion 15 having a disk 13 and a plurality of oil guide grooves 14 in the lower portion.
미설명 부호 16은 액냉매 흡입구멍이다.Reference numeral 16 is a liquid refrigerant suction hole.
이와같이 된 본 고안은 제4도에 도시된 바와같이 크랭크축(3)이 회전하면 배관 사이클내의 냉매는 냉동 사이클을 이루면서 에바(EVA)에서 나온 저온 저압의 냉매가 압축기내로 흡입된다.In the present invention, as shown in FIG. 4, when the crankshaft 3 rotates, the refrigerant in the piping cycle forms a refrigeration cycle, and the low temperature and low pressure refrigerant from EVA is sucked into the compressor.
흡입된 냉매는 압축기 용기 내부를 선회하다가 흡입구멍(16)을 통해 들어온다.The sucked refrigerant turns inside the compressor vessel and enters through the suction hole 16.
냉동사이클의 이상변동으로 인해 흡입구멍(16)을 통해 들어온 냉매는 액체로 존재하여 압축될시 압축기의 고장 원인이 된다.The refrigerant entering through the suction hole 16 due to an abnormal change in the refrigeration cycle is a liquid and causes a failure of the compressor when compressed.
때문에 액냉매가 들어올시 흡입구멍(16) 하단에 위치한 크랭크축(3) 상단부에 오일유도판(12)을 장설하여 제6도에서와 같이 유도판(12)에 받쳐져서 고정자(1)로 전달되어 고정자 냉각 및 액 압축방지를 할 수 있게한 것이다.Therefore, when the liquid refrigerant enters, the oil induction plate 12 is installed at the upper end of the crankshaft 3 located at the lower end of the suction hole 16, and supported by the guide plate 12 as shown in FIG. To prevent stator cooling and liquid compression.
따라서 압축기 하부에 고여 있던 오일은 크랭크축(3)의 회전 원심력으로 인해 내면의 오일통로(4)로 상승하게 되고, 상승된 오일은 크랭크축(3) 끝단에 삽착된 원판형의 오일 유도판(12)에 의해 비산된다.Therefore, the oil accumulated in the lower part of the compressor rises to the inner oil passage 4 due to the rotational centrifugal force of the crank shaft 3, and the raised oil is disc-shaped oil guide plate inserted at the end of the crank shaft 3 ( Scattered by 12).
즉, 크랭크축(3)의 상단 안내경사부(10)에 원판(13)으로 되고 다수의 오일 안내홈(14)을 가진 오일유도판(12)의 하단 안내연결부(15)를 압입시켜 삽착시키게 되면 크랭크축(3)의 다수 돌출요홈(11)과 오일유도판(12)의 오일안내홈(14)이 서로 일치가 되어 오일 비산홈을 형성하게 된다.That is, the upper guide inclined portion 10 of the crankshaft (3) to the disk 13 and the lower guide connecting portion 15 of the oil guide plate 12 having a plurality of oil guide grooves 14 to press-fit and insert. When the plurality of protruding groove 11 of the crankshaft (3) and the oil guide groove 14 of the oil guide plate 12 is matched with each other to form an oil splash groove.
이때, 상승된 오일은 돌출요홈(11)과 오일안내홈(14)을 통해 비산되는데, 오일유도판(12)의 상부는 원판(13)으로 되어 있기 때문에 비산되는 오일은 제6도에 도시된 바와같이 원판(13)의 외연 끝단까지 저면부를 타고 연결되므로서 고정자(1)까지 오일을 전달하게 되고, 흡입구멍(16)을 통해 들어온 액냉매는 오일유도판(12)의 원판 상면을 타고 고정자(l)로 연결되는 것이다.At this time, the raised oil is scattered through the protruding groove 11 and the oil guide groove 14, since the upper portion of the oil induction plate 12 is made of a disk 13, the oil splashed is shown in FIG. As the bottom portion is connected to the outer edge of the disc 13 as described above, the oil is delivered to the stator 1, and the liquid refrigerant entering through the suction hole 16 rides on the disc top surface of the oil induction plate 12. to (l).
이와같이 된 본 고안은 크랭크축(3)에서 상승된 오일과 흡입구멍(16)에서 들어온 액냉매를 원판(13)으로된 오일유도판(12)의 상. 하면에서 각각 유도하여 주므로서 오일과 액냉매를 고정자(1)에 확실히 전달하게 된다.The present invention as described above is an oil-induced plate (12) made of a disk (13) is a liquid refrigerant coming from the oil and suction hole (16) raised from the crankshaft (3). The oil and the liquid refrigerant are reliably delivered to the stator 1 by inducing each from the lower surface.
때문에 고정자의 냉각효과를 크게 증대시킬수 있고, 액냉매에 의한 압축기 고장을 방지할 수 있어서, 습동부의 이상 마모 및 충격으로 인한 파손 방지와 온도저하에 따른 압축기의 수명을 연장시키게 되는 유용한 고안인 것이다.Therefore, the cooling effect of the stator can be greatly increased, and the compressor failure due to the liquid refrigerant can be prevented, thereby preventing the damage caused by abnormal wear and impact of the sliding part and extending the life of the compressor due to the temperature decrease. .
