본 발명은 캔드 전동기의 이물질 끼임 방지장치에 관한 것으로, 특히 전동기의 내부에 원심 수류를 일으키는 날개를 형성하여 전동기 내부에 이물질이 끼이는 것을 방지하도록 한 캔드 전동기의 이물질 끼임 방지장치에 관한 것이다.The present invention relates to a foreign matter pinch prevention device of the canned motor, and more particularly to a foreign matter pinch prevention device of the canned motor to form a wing that causes centrifugal water flow inside the motor to prevent the foreign matter is caught in the motor.

종래의 캔드 전동기는 제1도 및 제2도에 그 일 실시형태가 도시되어 있다. 도면에서 1은 고정자 조립체, 2는 회전자 조립체를 보인 것으로, 고정자 조립체(1)의 회전자 조립체(2)가 베어링(3)과 트러스트 베어링(4)에 의해 지지되어 있어, 전원을 인가하면 임펠러(6)가 회전함에 따라 펌프 전동기의 내부로 물이 유입되어 베어링(3)과 회전자 축(10) 사이를 통하여 반부하측 베어링부까지 물이 가득차게 되며, 이때 물과 함께물속에 들어 있는 미세한 각종 이물질도 함께 들어온다.One embodiment of a conventional canned motor is shown in FIGS. 1 and 2. In the figure, 1 shows a stator assembly, 2 shows a rotor assembly, and the rotor assembly 2 of the stator assembly 1 is supported by the bearing 3 and the thrust bearing 4, and when the power is applied, the impeller As the 6 rotates, water flows into the pump motor, and the water is filled to the half load side bearing part between the bearing 3 and the rotor shaft 10, and the water contained in the water Various foreign objects also come in.

그리고, 상기한 바와 같이 내부로 물이 함께 들어온 이물질은 모터 내부에는 유속이 완만하기 때문에 침적되며, 베어링(3)과 회전자 축(10) 사이에도 끼이게 된다.And, as described above, foreign matters that enter the water together is deposited because the flow rate is gentle in the motor, it is also sandwiched between the bearing (3) and the rotor shaft (10).

도면에서 미설명 부호 5는 상기 트러스트 베어링(4)을 잡아주는 고무 홀더, 7은 고정자 캔(stator can), 8은 오링(O-ring)을 각각 보인 것이다.In the drawings, reference numeral 5 denotes a rubber holder holding the thrust bearing 4, 7 a stator can, and 8 an O-ring.

상기한 바와같은 종래의 캔드 전동기는 전동기의 내부로 물과 함께 들어온 이물질이 잘 빠지지 않고 대부분 침적되어 결국에는 전동기를 구속시키게 되고, 이물질이 어느 정도 쌓여 있을때는 인위적인 기동으로 펌프구동이 가능하나 계속 운전시키면 이물질이 계속 쌓여 완전히 구속되므로 인위적인 기동도 불가능하게되며, 특히 이물질이 베어링(3)과 회전자 축(10) 사이에 끼이거나 침적된 경우에는 더 쉽게 구속하여 전동기의 신뢰성을 저하시키는 결함이 되는 것이었다.As described above, the conventional canned motor is hard to fall out of foreign substances with water into the inside of the motor, and most of them are deposited and eventually constrain the motor. When some foreign matters are accumulated, the pump can be driven by artificial starting. If the foreign matter is accumulated and fully restrained, artificial maneuvering is impossible. Especially, when foreign matter is caught or deposited between the bearing 3 and the rotor shaft 10, the defect is more easily constrained to reduce the reliability of the motor. Was.

본 발명은 상기한 바와 같은 종래의 결함을 감안하여 창안한 것으로 전동기의 내부에 이물질이 끼이는 현상을 방지하여 전동기의 기동이 원활하게 되도록 함으로써 제품의 신뢰성을 향상할 수 있는 캔드 전동기의 이물질 끼임 방지장치를 제공하고자 함에 목적이 있다.The present invention was devised in view of the above-mentioned defects as described above, and prevents foreign substances from being caught inside the motor to smoothly start the motor, thereby preventing foreign substances from being caught in the canned motor, which can improve the reliability of the product. The purpose is to provide a device.

이러한 목적을 가지는 본 발명은 캔드 전동기의 내부에 원심 수류를 형성하여 유속을 증가시키기 위한 회전날개를 설치하여 전동기 내부에 이물질이 끼임을 방지하도록 구성된다.The present invention having such an object is configured to form a centrifugal water flow inside the canned motor to install a rotary blade to increase the flow rate to prevent foreign matter from being caught inside the motor.

이하, 이러한 본 발명 캔드 전동기의 이물질 끼임 방지장치를 첨부한 도면에 의하여 보다 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the foreign matter jamming prevention device of the present invention can electric motor is as follows.

제3도는 본 발명에 의한 캔드 전동기의 이물질 끼임 방지장치의 구성을 보인 단면도이고, 제4도는 고무 홀더를 발췌하여 보인 사시도로서, 이에 도시한 바와같이, 고정자 조립체(1)의 내측에 회전자 조립체(2)가 삽입되고, 회전자 축(10)의 양단부가 베어링(3)에 의하여 회전 가능하게 결합되어 있으며, 고무 홀더(5)에 의하여 지지되는 트러스트 베어링(4)에 의하여 길이 방향 유동이 억제되도록 결합되어 있다.Figure 3 is a cross-sectional view showing the configuration of the foreign matter jamming device of the canned motor according to the present invention, Figure 4 is a perspective view taken from the rubber holder, as shown therein, the rotor assembly inside the stator assembly (1) (2) is inserted, and both ends of the rotor shaft 10 are rotatably coupled by the bearings 3, and longitudinal flow is suppressed by the thrust bearings 4 supported by the rubber holders 5. Are combined as possible.

이러한 캔드 전동기의 이물질 끼임 방지장치에 있어서, 상기 고무 홀더(5)에는 제3도 및 제4도와 같이, 본 발명에 따라 부하 측면에 원심 수류를 형성하기 위한 복수개의 회전날개(5a)가 형성되어 있다.In the foreign matter pinch prevention device of the canned motor, the rubber holder (5) is formed with a plurality of rotary blades (5a) for forming a centrifugal water flow on the load side in accordance with the present invention, as shown in FIGS. have.

도면에서 미설명 부호 9는 체크 볼(check ball)을 보인 것이고, 그외 종래 구성과 동일한 부분은 동일 부호로 표시되어 있다.In the drawing, reference numeral 9 denotes a check ball, and the same parts as in the prior art are denoted by the same reference numerals.

상기한 바와 같은 본 발명은 트러스트 베어링(4)을 지지하는 고무 홀더(5)의 부하측면에 원심 수류를 일으키는 회전날개(5a)가 형성되어 있으므로 베어링(3)과 회전자 축(10) 사이로 들어오는 이물질이 상기 원심수류에 의해 빨라진 유속에 의하여 정체되어 끼이는 일이 없이 물과 함께 배출된다. 따라서 종래에 비하여 이물질 침적이 훨씬 감소된다.In the present invention as described above, since the rotary blades 5a for generating centrifugal flow are formed on the load side of the rubber holder 5 supporting the thrust bearing 4, the bearing 3 and the rotor shaft 10 enter between the bearing 3 and the rotor shaft 10. The foreign matter is discharged together with the water without being stuck by the flow velocity accelerated by the centrifugal flow. Therefore, foreign matter deposition is much reduced as compared with the prior art.

이상에서 설명한 바와 같은 본 발명은 트러스트 베어링(4)을 잡아주는 고무 홀더(5)의 부하측면에 원심 수류를 일으키는 회전날개(5a)를 형성하여 펌프 운전시 베어링(3)과 회전자 축(10) 사이로 들어오는 물의 유속을 빠르게 함으로써 베어링(3)과 회전자 축(10) 사이에 이물질이 끼이거나 침적되는 현상을 방지하도록 되어 있으므로 이물질의 침적에 의한 전동기의 기동이 불가능하게 되는 결함을 해소하여 제품의 신뢰성을 향상하는 이점이 있다.As described above, the present invention forms a rotor blade 5a that causes centrifugal flow on the load side of the rubber holder 5 holding the thrust bearing 4 so that the bearing 3 and the rotor shaft 10 during pump operation. By speeding up the flow rate of water coming in through), it is possible to prevent foreign matters from being caught or deposited between the bearings 3 and the rotor shaft 10. This eliminates the defect that makes it impossible to start the motor by depositing foreign matters. There is an advantage to improve the reliability.
