도 2는 본 발명에 따른 워셔 펌프를 나타낸 사시도,
도 3은 본 발명에 따른 워셔 펌프의 '커버'를 나타낸 도면.1 is a view showing a conventional washer liquid injection device,
2 is a perspective view showing a washer pump according to the present invention,
Figure 3 shows a 'cover' of the washer pump according to the present invention.

이하 본 발명의 바람직한 실시예를 첨부된 도면을 토대로 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 워셔 펌프를 나타낸 사시도, 도 3은 본 발명에 따른 워셔 펌프의 '커버'를 나타낸 도면이다.2 is a perspective view showing a washer pump according to the present invention, Figure 3 is a view showing a 'cover' of the washer pump according to the present invention.

도 2 및 도 3에 나타낸 바와 같이, 본 발명에 따른 워셔 펌프(P)는 흡입 및 토출압력을 발생시키는 모터(미도시)와 임펠러(6)가 내부에 결합되고 외측에 흡입부(3)가 형성된 본체(2); 상기 본체(2)의 일단부에 결합되며 토출부(5)가 형성된 커버(4)를 포함한다.As shown in Figure 2 and 3, the washer pump (P) according to the present invention is a motor (not shown) and the impeller (6) for generating the suction and discharge pressure is coupled to the inside and the suction portion (3) on the outside A formed body 2; The cover 4 is coupled to one end of the main body 2 and has a discharge part 5 formed thereon.

상기 커버(4)는 도 3에 나타낸 바와 같이, 원형 판상이며 일측에는 상기 임펠러(6)가 삽입될 수 있도록 오목하게 패여진 챔버(40)가 형성되고, 커버(4)의 외주면에는 접선방향으로 일정 길이의 토출부(5)가 형성된다.As shown in FIG. 3, the cover 4 has a circular plate shape, and on one side thereof is formed a concave recessed chamber 40 so that the impeller 6 can be inserted therein, and on the outer circumferential surface of the cover 4 in a tangential direction. The discharge part 5 of a predetermined length is formed.

상기 토출부(5)는 상기 챔버(40)와 통하는 유로(50)가 내측에 형성되고 일단에 개구공(504)이 형성된 관부재(52)와, 상기 챔버(40)와 유로(50)가 연결되는 부위인 유입공(502)에 유로(50) 보다 직경이 작게 형성된 환턱(503)을 포함한다.The discharge part 5 includes a pipe member 52 having a flow path 50 communicating with the chamber 40 formed therein and an opening hole 504 formed at one end thereof, and the chamber 40 and the flow path 50 being connected to each other. The inlet hole 502, which is a portion to be connected, includes a round jaw 503 having a smaller diameter than the flow path 50.

상기 관부재(52)의 끝단에 워셔 노즐과 연결되는 호스가 연결된다.A hose connected to the washer nozzle is connected to the end of the pipe member 52.

바람직하게는 호스의 결합 상태를 강화시키기 위해 상기 토출부(5)의 끝단 외주면에는 경사면을 갖는 걸림턱(524)이 형성된다.Preferably, the locking step 524 having an inclined surface is formed on the outer peripheral surface of the end of the discharge portion 5 to strengthen the coupling state of the hose.

따라서 상기 걸림턱(524)에 의해 호스를 끼우기는 용이하나 일단 결합된 호스는 잘 빠지지 않게 된다.Therefore, it is easy to fit the hose by the locking jaw 524, but the hose once combined is not easily pulled out.

한편 본 발명의 주된 특징은 상기 토출부(5)에 역류가 방지되도록 체크밸브가 설치되는 것이다.On the other hand, the main feature of the present invention is that the check valve is installed to prevent the reverse flow in the discharge portion (5).

즉 임펠러(6)의 회전에 의해 흡입된 워셔액이 토출부(5)를 통해 호스로 공급되는데, 임펠러(6)가 정지된 상태일때 호스 내의 워셔액이 다시 챔버(40)로 역류되지 않도록 차단시킬 필요가 있다. That is, the washer fluid sucked by the rotation of the impeller 6 is supplied to the hose through the discharge part 5, and when the impeller 6 is in a stopped state, it is necessary to block the washer fluid from flowing back into the chamber 40 again. There is.

따라서 워셔액이 역류될 경우 체크밸브가 작동되어 워셔액의 흐름이 차단되도록 한다.Therefore, when the washer fluid flows back, the check valve is operated to block the flow of the washer fluid.

상기 체크밸브는 상기 토출부(5)의 내부에 삽입되어 유입공(502)을 막는 구체(54)와, 상기 구체(54)를 지지하도록 토출부(5)에 삽입된 스프링(56)을 포함한다.The check valve includes a sphere 54 inserted into the discharge portion 5 to block the inlet hole 502 and a spring 56 inserted into the discharge portion 5 to support the sphere 54. do.

따라서 워셔액의 정방향 흐름, 즉 임펠러(6)의 회전에 의해 워셔액이 토출부(5)를 통해 호스로 공급되는 흐름일 경우 펌핑 압력에 의해 구체(54)가 환턱(503)으로부터 이격되고 스프링(56)은 수축된 상태가 되므로 정방향 흐름은 원활하게 유지될 수 있다.Therefore, when the washer fluid flows, that is, the flow of the washer fluid supplied to the hose through the discharge part 5 by the rotation of the impeller 6, the sphere 54 is spaced apart from the round jaw 503 by the pumping pressure and the spring 56 is applied. ) Is contracted so that the forward flow can be maintained smoothly.

반면 워셔 펌프(P)가 정지되어 임펠러(6)가 회전되지 않을때는 펌핑 압력이 없으므로 스프링(56)의 탄발력에 의해 구체(54)가 환턱(503)에 밀착됨으로써 유로(50)는 폐쇄된다.On the other hand, when the washer pump P is stopped and the impeller 6 is not rotated, there is no pumping pressure. Therefore, the spherical body 54 is in close contact with the round jaw 503 due to the spring force of the spring 56, thereby closing the flow path 50. .

특히 역방향의 흐름이 발생될 경우 구체(54)를 더욱 환턱(503)에 밀착시키게 되므로 유로(50)가 폐쇄되어 호스에 차있던 워셔액이 챔버(40) 내로 유입될 수 없다.Particularly, when the reverse flow occurs, the sphere 54 is further brought into close contact with the round jaw 503, so that the flow path 50 is closed so that the washer fluid filled in the hose cannot be introduced into the chamber 40.

비록 본 발명이 상기 언급된 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
