Description

에어컨의 냉매 점검용 공구{tool for checking refrigerant of an air conditioner}Tool for checking refrigerant of an air conditioner

본 발명은 에어컨의 냉매 점검용 공구에 관한 것이다.The present invention relates to a tool for checking a refrigerant of an air conditioner.

가정용 에어콘, 차량용 에어콘 등 각종 에어컨은 제조된 후, 그 냉매라인에 냉매를 충전하고, 냉매의 충전여부를 점검한 후 출고하게 된다.After the various air conditioners such as home air conditioners and vehicle air conditioners are manufactured, the refrigerants are charged in the refrigerant lines, and the containers are shipped after the refrigerant is charged.

도1에 도시한 바와 같이, 냉매라인에는 냉매를 충전하기 위한 니플부(2)가 형성되어 있다. 상기 니플부(2)는 냉매 파이프(4)에 일체로 형성되며 외측으로 돌출된 니플 몸체(6)와, 상기 니플 몸체(6)의 내부에 고정결합되며 밸브자리(8a)가 형성된 마감부재(8)와, 상기 마감부재(8)을 상하로 관통하여 이동가능케 설치된 밸브봉(10)과, 상기 밸브봉(10)에 탄성복원력을 가하도록 밸브봉(10)에 결합된 스프링(12)을 구비한다.As shown in Fig. 1, a nipple portion 2 for filling a refrigerant is formed in the refrigerant line. The nipple portion 2 is integrally formed in the refrigerant pipe 4 and the nipple body 6 protruding outwardly, and the closing member fixedly coupled to the inside of the nipple body 6 and the valve seat 8a is formed ( 8), a valve rod 10 installed to move through the closing member 8 up and down, and a spring 12 coupled to the valve rod 10 to apply elastic restoring force to the valve rod 10. Equipped.

상기 니플 몸체(6)는 그 상측부 내면에 나사(6a)가 형성되고 외면에 리세스부(6b)가 형성된다. 상기 마감부재(8)는 상기 니플 몸체(6)에 나사결합되며, 마감부재(8)의 중앙에는 상기 밸브봉(10)이 삽입되는 구멍이 형성된다. 상기 스프링(12)은 상기 밸브봉(10)의 상부에 외삽되는데, 상기 마감부재(8)의 상단면과 상기 밸브봉(10)의 상단 사이에 위치한다.The nipple body 6 has a screw 6a formed on an inner surface of an upper portion thereof and a recessed portion 6b formed on an outer surface thereof. The closing member (8) is screwed to the nipple body (6), a hole in which the valve rod 10 is inserted is formed in the center of the closing member (8). The spring 12 is extrapolated to the upper portion of the valve rod 10, which is located between the upper end surface of the closing member (8) and the upper end of the valve rod (10).

상기 니플 몸체(6)의 상부에 도시하지 않은 냉매 충전기의 단부를 결합하여 조작하면, 상기 밸브봉(10)이 눌리면서 냉매파이프의 내부로 냉매가 주입하게 된다. 그리고, 제품의 출고후 또는 정비업소에는 도1에 도시한 바와 같이 드라이브등의 뾰족한 물체로 밸브봉(10)을 눌러서 냉매가 빠져 나오는 것을 보고 냉매 충전여부를 점검한다.When the end of the refrigerant charger (not shown) is coupled to and operated on the upper portion of the nipple body 6, the valve rod 10 is pressed to inject refrigerant into the refrigerant pipe. Then, after shipment of the product or maintenance shop, as shown in FIG. 1, by pressing the valve rod 10 with a sharp object such as a drive, the refrigerant is ejected to check whether the refrigerant is charged.

그런데, 제품의 출고 후에는 제품의 품질을 확인하기 위해서 여러차례 냉매충전 여부를 점검하게 된다. 예를 들어 수출제품의 경우에는 수출지역항구 및 딜러 삽(dealer shop)등에서도 밸브봉을 눌러 냉매 충전여부를 점검하게 된다.However, after the product is shipped, the refrigerant is charged several times to check the quality of the product. For example, in the case of export products, the valve rod is pressed at the export port and the dealer shop to check whether the refrigerant is charged.

이와 같이 빈번하게 제품에 대한 냉매 충전여부를 점검하게 됨으로 인해, 많은 양의 냉매가 손실되어 고객에게 제품이 인도된 후 냉매부족 현상이 발생하게 된다는 문제점이 있었다.As a result of frequently checking whether the product is charged with the refrigerant, a large amount of the refrigerant is lost, and there is a problem that the refrigerant shortage occurs after the product is delivered to the customer.

그리고, 냉매의 유출소리를 듣고 냉매 충전여부를 점검하므로 정확한 점검이 이루어지지 않으며, 많은 양의 냉매가 유출됨으로 인해 환경오염을 크게 한다는 문제점이 있었다.In addition, since the refrigerant is leaked and the refrigerant is charged, the refrigerant is not accurately checked, and a large amount of the refrigerant is leaked, thereby increasing the environmental pollution.

따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 냉매충전여부를 점검할 시에 냉매 손실을 최소화하고 냉매충전여부를 간편하고 정확히 점검할 수 있는 에어컨의 냉매 점검용 공구를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to check the refrigerant charging tool for minimizing the refrigerant loss and to check the refrigerant charge simply and accurately the refrigerant charging tool To provide.

Combined.

이와 같이 구성된 본 발명에 의한 에어컨의 냉매 점검용 공구는 도3에 도시한 바와 같이 냉매 파이프(4)에 형성된 니플부(2)의 니플 몸체(6)에 결합하여 사용한다. 결합시에는 구속부재(32)의 플랜지(32a)을 잡고 위로 잡아 당긴 상태에서,니플부(2)의 상부가 점검 몸체(20)의 제1공간부(S1)에 수용되게 하면서 볼(30)이 니플 몸체(6)의 리세스부(6b)에 걸리게 한 다음, 구속부재(32)를 놓으면, 니플 몸체(6)의 상단부가 시일부재(28)에 밀착하면서 냉매 점검용 공구의 결합이 간단히 완료된다. 이때 조작봉(26)의 돌기(52)는 제3공간부(S3)에 걸리고, 조작봉(26)의 하단부는 니플부(2)의 밸브봉(10)에 닿지 않은 상태로 된다.The refrigerant checking tool of the air conditioner according to the present invention configured as described above is used in combination with the nipple body 6 of the nipple portion 2 formed in the refrigerant pipe 4 as shown in FIG. At the time of engagement, while holding the flange 32a of the constraining member 32 and pulling it upward, the ball 30 is allowed to be accommodated in the first space S1 of the inspection body 20 by the upper portion of the nipple portion 2. After engaging the recessed portion 6b of the nipple body 6, and then placing the restraining member 32, the upper end of the nipple body 6 comes into close contact with the seal member 28, so that the engagement of the refrigerant check tool is easily combined. Is done. At this time, the projection 52 of the operating rod 26 is caught by the third space portion S3, and the lower end of the operating rod 26 is not in contact with the valve rod 10 of the nipple portion 2.

이와 같은 상태에서, 도4에 도시한 바와 같이 핸들을 화살표 A방향으로 돌리면서 화살표 B방향으로 내려 누르면, 조작봉(26)의 하단부는 밸브봉(10)을 밀게 되어, 냉매 파이프(4)의 냉매가 제1공간부(S1)에 차면서 피스톤(38)은 우측으로 밀린다. 점검자는 관찰창(42)을 통해 피스톤(38)의 위치를 확인하여 냉매의 충전상태를 정확히 알 수 있다. 상기 조작봉(26)은 원타치식으로 한번만 눌러다 놓으면 제1공간부(S1)에 냉매압이 가해지고 제1스프링(31)의 복원력에 의해 원위치하므로, 조작이 간편하다.In this state, as shown in Fig. 4, when the handle is turned down in the direction of arrow B while being rotated in the direction of arrow A, the lower end portion of the operating rod 26 pushes the valve rod 10, so that the coolant pipe 4 As the refrigerant fills the first space S1, the piston 38 is pushed to the right. The inspector can check the position of the piston 38 through the observation window 42 to accurately know the state of charge of the refrigerant. When the operating rod 26 is pressed once only by a one-touch method, the refrigerant pressure is applied to the first space S1 and the original position is restored by the restoring force of the first spring 31, so that the operation is easy.

그리고, 냉매는 제1공간부(S1)에 차는 양만 손실되므로 냉매 손실양을 최소로 할 수 있다. 이 경우 제1공간부(S1)에는 공기가 차 있는 상태에서 냉매가 차게되므로 냉매압으로 인해 공기가 압축되어 차지하는 공간만큼 냉매 손실량은 더욱 작게 된다.In addition, since the amount of the refrigerant lost in the first space portion S1 is lost, the amount of refrigerant loss may be minimized. In this case, since the refrigerant is filled in the air in the first space S1, the amount of refrigerant loss is further reduced as much as the space occupied by the air due to the refrigerant pressure.

한편, 조작봉(26)을 눌렸다 놓은 후에는 화살표 A방향에 대해 역방향으로 회전시켜 그 돌기(52)가 제3공간부(S3)에 걸리게 하여 상하로 이동하지 않게 한다On the other hand, after pressing and releasing the operating rod 26, it rotates in the reverse direction with respect to the arrow A direction so that the projection 52 is caught by the third space S3 so as not to move up and down.

냉매 점검이 끝나면, 구속부재(32)의 플랜지(32a)을 잡고 위로 밀어 올려, 점검 몸체(20)을 상측으로 빼내면, 볼(30)이 리세스부(6b)에서 이탈하여 냉매 점검용 공구가 니플부(2)에서 분리된다. 그리고 제3스프링(40)에 의해 피스톤(38)은 원위치된다.After the coolant check is finished, grasp the flange 32a of the restraining member 32 and push it up, and when the check body 20 is pulled out upward, the ball 30 is released from the recess 6b and the coolant check tool. Is separated from the nipple portion (2). And the piston 38 is returned to its original position by the third spring (40).

본 발명에 의한 에어컨의 냉매 점검용 공구에 의하면, 냉매충전여부를 점검할 시에 냉매 손실을 최소화하여 에어컨의 품질 저하를 방지하는 한편 환경 오염을 줄일 수 있고, 냉매충전여부를 간편하고 정확히 점검할 수 있는 효과가 있다.According to the tool for checking a refrigerant of an air conditioner according to the present invention, it is possible to minimize the loss of refrigerant when checking whether the refrigerant is charged, to prevent deterioration of the quality of the air conditioner while reducing environmental pollution, and to easily and accurately check whether the refrigerant is charged. It can be effective.
