Description

실내기와 실외기 상호 간을 연결하는 다중케이블 구조{Structure of multi cable connecting indoor unit and outdoor unit in air-conditioning system}Structure of multi cable connecting indoor unit and outdoor unit in air-conditioning system}

본 발명은 실내기와 실외기 상호 간을 연결하는 다중케이블 구조로서, 실내기 및 실외기 각각에 수용체가 구비되는 연결부를 마련하고 양단 부위 각각에 삽입체가 구비되는 케이블을 이들 연결부 각각과 간편하게 연결하도록 구성함으로써, 비숙련공이라도 매우 편리하게 연결 작업을 수행할 수 있음은 물론 냉매 호스의 연결 부위를 통해 냉매가 누설되는 현상을 원천적으로 방지하는 것이 가능하며, 나아가 배관 내부에 채워져 있는 냉매를 제거하지 않은 상태로 케이블을 단지 분리하여 이동한 다음 재장착하여 사용할 수 있는 다중케이블 구조에 관한 것이다.The present invention is a multi-cable structure that connects the indoor unit and the outdoor unit with each other, by providing a connection portion provided with a receptor in each of the indoor unit and the outdoor unit, and configured to easily connect the cable provided with inserts at each end portion thereof with each of these connection portions, Even a skilled worker can carry out the connection work very conveniently, and it is possible to prevent the leakage of refrigerant through the connection part of the refrigerant hose at the source. Furthermore, the cable can be removed without removing the refrigerant filled in the pipe. It relates to a multi-cable construction that can only be removed, moved and then remounted.

통상적인 공기조화기는 사람들이 활동하는 공간에 설치되는 실내기 및 옥외에 설치되는 실외기가 분리 구성된다. 이때, 실내기에는 증발기와 송풍팬을 마련하고, 실외기에는 압축기와 응축기를 마련하며, 실내기 및 실외기 상호 간은 배관 등에 의해 연결하여 냉매를 순환시킨다. A typical air conditioner is composed of an indoor unit installed in a space where people are active and an outdoor unit installed outdoors. At this time, the indoor unit is provided with an evaporator and a blowing fan, the outdoor unit is provided with a compressor and a condenser, and the indoor unit and the outdoor unit are connected to each other by a pipe or the like to circulate the refrigerant.

공기조화기에 있어 냉매를 순환시키는 배관은 대개의 경우 동과 같은 금속관으로 이루어지며, 이들 냉매 배관은 응축수를 배출시키기 위해 길게 연장 형성되는 배수관과 전원 및 제어신호를 송출하는 케이블과 함께 보온용 테이프 등에 의해 감싸진 상태로 실내에서 실외로 인출된다.In the air conditioner, the pipes circulating the refrigerant are usually made of metal pipes such as copper, and these refrigerant pipes are provided with a heat insulating tape, a drain pipe, which is formed to extend condensate, and a cable for transmitting power and control signals. It is drawn from the indoor to the outdoor in a wrapped state.

그런데, 이러한 인출 구성은 배관을 연결하거나 해체하는 작업이 번거로울 뿐 아니라, 해체한 다음에 배관을 연결하는 경우 배관에 냉매를 추가적으로 보충해야 하는 문제가 있었다. 이러한 문제를 해결하기 위해, 냉매 배관, 응축수 배관, 케이블 등을 튜브 내에 동시에 내장하여 시공하는 방식이 제안되었다. However, such a drawing configuration has a problem in that it is not only troublesome to connect or dismantle the pipe, but additionally refrigerate the pipe when the pipe is connected after dismantling. In order to solve this problem, a method of constructing a refrigerant pipe, a condensate pipe, a cable, and the like at the same time has been proposed.

이러한 부류의 기술은 도 10에 개시된 것과 같이, 배관 및 케이블을 단일 부재의 몰드형 배관으로 구성하고, 실내기 및 실외기 각각과는 별도의 암, 수연결구와 같은 커넥터를 이용하여 한 번에 다수의 냉매커넥터 및 전원, 그리고 통신선을 결합하는 방식으로 이루어짐에 그 특징이 있다.This class of technology consists of a single piece of molded tubing and cables, as shown in FIG. 10, and a plurality of refrigerant connectors at a time using connectors such as female and male connectors separate from the indoor and outdoor units, respectively. And a power source and a communication line.

이럴 경우, 숙련공이 아니더라도 공기조화기의 배관 연결을 매우 편리하게 할 수 있음은 물론 밀폐 구조가 형성되어 있다는 점에서 배관 교체 작업과정에서 냉매를 추가로 주입할 필요가 없으며, 작업이 완료된 이후에 별도의 뒤처리 작업을 수행하지 않더라도 외관상 깔끔한 마무리가 이루어진다는 점에서 하나의 대안으로 눈여겨볼 만하다. In this case, even if you are not a skilled worker, it is very convenient to connect the piping of the air conditioner, and since the sealed structure is formed, it is not necessary to inject additional refrigerant during the pipe replacement work. Even if you do not do the post-treatment work, it is worth considering as an alternative in that the appearance is clean.

하지만, 이러한 장점에도 불구하고 현재 제안되고 있는 이러한 부류의 기술들은 몰드 배관과 실내기(및 실외기) 상호 간의 연결 작업 자체가 여전히 번거롭다는 문제가 있으며, 특히 그 연결 부위가 긴밀하게 폐쇄되지 못하여 실내기나 실외기의 위치를 이동 설치하는 경우 배관에 채워져 있던 냉매를 제거한 다음 다시 냉매를 주입해야 하는 문제가 있었다. However, in spite of these advantages, this type of technology currently proposed has a problem that the connection between the mold piping and the indoor unit (and the outdoor unit) is still cumbersome, and in particular, the connection part is not closed tightly. In the case of moving and installing the location of the outdoor unit, there was a problem of removing the refrigerant that was filled in the pipe and then injecting the refrigerant again.

하지만, 본 발명과 같이 제1, 2, 3, 4수용체(14, 16, 24, 26) 각각에 제1, 2, 3, 4냉매배기홈(147, 167, 247, 267) 각각을 형성하게 되면, 도 6a와 같이 케이블부(30)의 양단부위 각각이 제1, 2연결부(10, 20) 각각과 분리되는 시점에서, 제1, 2삽입체(34, 36)의 양단부위 외면과 제1, 2수용체(14, 16)의 타단부위 내면 및 제3, 4수용체(24, 26)의 일단부위 내면 사이에는 일정크기의 공간이 형성된다.However, as in the present invention, each of the first, second, third, and fourth refrigerant exhaust grooves 147, 167, 247, and 267 is formed in each of the first, second, third, and fourth receptors 14, 16, 24, and 26. 6A, when both ends of the cable part 30 are separated from each of the first and second connection parts 10 and 20, as illustrated in FIG. 6A, the outer and outer surfaces of both ends of the first and second inserts 34 and 36 are formed. A space of a predetermined size is formed between the inner surface of the other end of the first and second receptors 14 and 16 and the inner surface of one end of the third and fourth receptors 24 and 26.

케이블부의 양단부위 각각이 실내기의 제1연결부 및 실외기의 제2연결부 각각과 분리될 때, 케이블부, 실내기, 실외기 각각의 냉매호스 단부는 각 탄성수단의 복원력에 의해 각 개폐체가 원위치로 복귀하면서 밀폐되어 냉매의 누설이 방지되나, 케이블부의 삽입체 및 제1, 2연결부 각각의 수용체 사이 공간에 일정양의 냉매가 잔존한다. When each of both ends of the cable part is separated from each of the first connection part of the indoor unit and the second connection part of the outdoor unit, the refrigerant hose ends of each of the cable part, the indoor unit, and the outdoor unit are closed while each switch is returned to its original position by the restoring force of each elastic means. The leakage of the refrigerant is prevented, but a certain amount of refrigerant remains in the space between the insert of the cable part and the receptor of each of the first and second connection parts.

이처럼 케이블부의 삽입체 및 제1, 2연결부 각각의 수용체 사이 공간에 잔존하는 일정양의 냉매는, 제1, 2삽입체의 양단부위 외면과 제1, 2수용체의 타단부위 내면 및 제3, 4수용체의 일단부위 내면 사이에 형성되는 바로 이 공간을 통해 조금씩 빠져나가게 된다. 이에 따라, 냉매의 압력은 자연스럽게 저하되어 종래와 같은 사고는 미연에 방지할 수 있게 되는 것이다.Thus, a certain amount of the refrigerant remaining in the space between the insert of the cable part and the receiver of each of the first and second connection parts is the outer surface of both ends of the first and second inserts, the inner surface of the other end of the first and second receptors, and the third and fourth. It gradually escapes through this space formed between the inner surface of one end of the receptor. Accordingly, the pressure of the refrigerant is naturally lowered, so that an accident as in the related art can be prevented in advance.
