Description
본 발명은 분리형 공기조화기에 관한 것으로, 특히 실내기와 실외기간의 냉매관을 연결시키는 서비스밸브에 관한 것이다.The present invention relates to a separate type air conditioner, and more particularly, to a service valve connecting a refrigerant pipe between an indoor unit and an outdoor period.
일반적으로, 에어컨과 같은 공기조화기의 실외기 일측에는 실내기와 실외기를 연결하여 진공 및 냉매 주입을 하기 위한 서비스밸브가 설치되어 있다.In general, a service valve is installed at one side of an outdoor unit of an air conditioner such as an air conditioner to connect an indoor unit and an outdoor unit to inject vacuum and refrigerant.
도 1과 도 2에 도시된 바와 같이, 종래의 서비스밸브는 내부에 실외기측 냉매순환관(107)과 실내기측 냉매순환관(108)이 연결되는 냉매순환유로(102)가 형성되고 상기 냉매순환유로(102)의 일측에 냉매주입유로(104)가 연통되어 형성된 밸브몸체(101)와, 상기 냉매주입유로(104)로 냉매를 주입시키는 냉매주입기구(106)와, 상기 밸브몸체(101)의 냉매순환유로(102)를 개폐하는 스핀들(110)로 구성되어 있다.As shown in FIG. 1 and FIG. 2, the conventional service valve has a refrigerant circulation passage 102 through which an outdoor unit side refrigerant circulation tube 107 and an indoor unit side refrigerant circulation tube 108 are connected, and the refrigerant circulation is performed. The valve body 101 formed by communicating with the refrigerant injection passage 104 on one side of the flow passage 102, a refrigerant injection mechanism 106 for injecting refrigerant into the refrigerant injection passage 104, and the valve body 101. The spindle 110 is configured to open and close the refrigerant circulation passage 102.
상기 스핀들(110)은 상기 냉매순환유로(102)를 가로지르는 방향으로 나사결합되고, 냉매순환유로(102) 상에 형성되는 개폐포트(105)를 개폐하여 냉매의 순환을 제어하게 된다.The spindle 110 is screwed in a direction crossing the refrigerant circulation passage 102 and controls the circulation of the refrigerant by opening and closing the opening and closing port 105 formed on the refrigerant circulation passage 102.
종래의 스핀들(110)은 헤드부(111)에 렌치홈(112)이 형성되고, 렌치를 이용하여 축회전시킴으로써 스핀들(110)을 작동시키게 되는데, 렌치가 없으면 작동이 어려우므로 실내기와 실외기의 분리작업을 하는 작업자는 렌치를 항상 휴대해야 하는 불편함이 있었다.In the conventional spindle 110, the wrench groove 112 is formed in the head 111, and the spindle 110 is operated by axial rotation using a wrench. However, without the wrench, it is difficult to operate the separation of the indoor unit and the outdoor unit. Workers who work have the inconvenience of always carrying a wrench.
즉, 렌치는 통상의 드라이버와는 달리 직경이 조금이라도 맞지 않을 경우 전혀 동작을 시킬 수 없으므로 수리하는 작업자의 경우에도 장비를 갖추어야 하는 불편함이 있는 것이다. In other words, unlike a normal screwdriver, the wrench can not be operated at all if the diameter does not fit even a little, so even if the worker to repair is inconvenient to equip the equipment.
이에 본 발명은 상기한 바의 제반 문제점들을 해소하기 위해 안출된 것으로, 드라이버나 렌치와 같은 별도의 조임기구 없이 간편하게 작동시켜 냉매순환유로를 개폐할 수 있는 분리형 공기조화기의 서비스밸브 개폐장치를 제공함에 그 목적이 있다. Accordingly, the present invention has been made to solve the above problems, and provides a service valve opening and closing device of a separate type air conditioner that can be opened and closed by simply operating without a separate tightening mechanism such as a screwdriver or wrench. Has its purpose.
상기한 바의 목적을 달성하기 위한 본 발명은, The present invention for achieving the above object,
이하 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 분리형 공기조화기의 서비스밸브 개폐장치는, 밸브몸체(1)의 냉매순환유로(2)를 개폐하는 스핀들(10)과, 상기 스핀들(10)의 상부 일측에 선회가능하게 힌지결합되는 N극 손잡이(20)와, 상기 스핀들(10)의 상부 일측에 선회가능하게 힌지결합되는 S극 손잡이(30)로 구성되어 있다.The service valve opening and closing device of the separate type air conditioner according to the present invention includes a spindle (10) for opening and closing a refrigerant circulation passage (2) of the valve body (1), and hinged rotatably to an upper one side of the spindle (10). Consists of the N pole handle 20 and the S pole handle 30 is hinged to the upper side of the spindle 10 to be pivotally rotatable.
상기 밸브몸체(1)는 냉매순환유로(2)의 일측에 스핀들 수용부(3)가 연통되어 형성되고, 그 스핀들 수용부(3)에 스핀들(10)이 나사식으로 회전가능하게 결합되어 있다.The valve body 1 is formed by communicating with the spindle receiving portion 3 on one side of the refrigerant circulation passage 2, and the spindle 10 is rotatably coupled to the spindle receiving portion 3 in a threaded manner. .
상기 스핀들(10)은 헤드부(11)의 상부 평면에 힌지부(12)가 돌출되어 형성되고, 그 힌지부(12)에 N극 손잡이(20)와 S극 손잡이(30)가 힌지결합된다.The spindle 10 is formed by the hinge portion 12 protrudes in the upper plane of the head portion 11, the N pole handle 20 and the S pole handle 30 is hinged to the hinge portion 12. .
상기 N극 손잡이(20)와 S극 손잡이(30)는 반원형상의 박판으로 형성되고, 양단에 힌지결합돌기(21,31)가 반경방향으로 연장되어 형성됨으로써 상기 힌지부(12)에 선회가능하게 힌지결합된다.The N-pole handle 20 and the S-pole handle 30 are formed in a semi-circular thin plate, the hinge coupling protrusions 21 and 31 are formed extending in the radial direction at both ends so as to pivot on the hinge portion 12. Hinged.
상기 N극 손잡이(20)와 S극 손잡이(30)는 상기 스핀들 헤드부(11)의 상부 평면을 가로지르는 힌지축을 회전축으로 하여 선회하게 되며, 각각의 회전축이 소정간격을 두고 서로 평행하게 구비되고 서로 포개어질 수 있도록 인접하게 구비되며, 자성에 의해 서로 탈착가능하게 된다.The N-pole handle 20 and the S-pole handle 30 are pivoted by a hinge axis across the upper plane of the spindle head portion 11 as the rotation axis, and each rotation axis is provided in parallel with each other at a predetermined interval. They are provided adjacent to each other so that they can be stacked on each other, and are detachable from each other by magnetism.
상기 N극 손잡이(20)와 S극 손잡이(30)는 서로 다른 극성으로 되어 서로 포개어진 상태에서 달라 붙게 되고, N극 손잡이(20)의 힌지점과 S극 손잡이(30)의 힌지점의 위치가 고정된 상태에서 N극 손잡이(20)와 S극 손잡이(30)의 일측이 달라 붙어 고정되면 전체적으로 삼각구도를 이루어 견고한 손잡이의 역할을 하게 된다.The N-pole handle 20 and the S-pole handle 30 becomes different polarity and stick together in a superimposed state, the position of the hinge point of the N-pole handle 20 and the hinge point of the S-pole handle 30. One side of the N-pole handle 20 and the S-pole handle 30 is attached to the fixed state in the fixed state to form a triangular sphere as a whole to serve as a solid handle.
상기 N극 손잡이(20)와 S극 손잡이(30)는 스핀들을 회전시킬 경우에만 서로 접촉시키고 사용하지 않을 경우에는 소정의 힘을 가해 서로 탈거시켜 스핀들(10) 헤드부(11)의 상부 표면에 안착시키게 된다.The N-pole handle 20 and the S-pole handle 30 are in contact with each other only when the spindle is rotated, and when not in use, the N-pole handle 20 is removed from each other by applying a predetermined force to the upper surface of the head portion 11 of the spindle 10. To be seated.
따라서, 상기 스핀들(10)이 최상단으로 이동하여 냉매순환유로(2)를 완전히 개방한 상태에서도 N극 손잡이(20)와 S극 손잡이(30)를 분리시킨 상태에서는 스핀들 수용부(3)의 외측으로 돌출되지 않게 되고, 스핀들(10)의 개폐위치에 상관없이 스핀들마개를 원활하게 덮을 수 있게 된다. Therefore, even when the spindle 10 moves to the uppermost end and the N-pole handle 20 and the S-pole handle 30 are separated even when the refrigerant circulation passage 2 is completely opened, the outer side of the spindle receiving portion 3 It is not protruded to, it is possible to smoothly cover the spindle plug regardless of the opening and closing position of the spindle (10).
이상에서 설명한 바와 같이 본 발명에 따른 분리형 공기조화기의 서비스밸브 개폐장치에 의하면, 별도의 조임기구 없이 스핀들을 용이하게 회전시켜 냉매순환유로를 개폐할 수 있고, 스핀들의 개폐위치에 무관하게 스핀들마개를 원활하게 닫을 수 있는 효과가 있다.As described above, according to the service valve opening and closing device of the separate air conditioner according to the present invention, the spindle can be opened and closed by easily rotating the spindle without a separate fastening mechanism, and the spindle plug is independent of the opening and closing position of the spindle. There is an effect that can be closed smoothly.
