본 발명은 벽걸이형 실내기의 횡단류팬에 관한 것으로서, 보다 상세하게는 상기 횡단류팬의 각 단들이 독립적으로 형성되고, 각 단들 사이가 착탈구조로 구성되어 손쉽게 횡단류팬의 전체 전장길이를 늘이고 줄일 수 있도록 한 벽걸이형 실내기의 횡단류팬에 관한 것이다.The present invention relates to a crossflow fan of a wall-mounted indoor unit, and more particularly, each end of the crossflow fan is formed independently, and each end of the crossflow fan is configured to be detachable so that the total length of the crossflow fan can be easily increased and reduced. A crossflow fan of a wall-mounted indoor unit.

통상, 공기조화기는 모든 기후조건과 실내환경에 따라서 최적의 온도 및 습도를 유지하기 위한 것으로, 실내공기를 시원하게 하거나 따뜻하게 하는 냉방장치 및 난방장치를 비롯하여, 습도를 적당하게 유지하기 위한 가습장치와, 실내공기를 외부로 배출시키는 환기장치 등이 포함된다.In general, the air conditioner is to maintain the optimum temperature and humidity according to all climatic conditions and indoor environment, including a cooling device and heating device to cool or warm the indoor air, and a humidifier to maintain the humidity properly; Ventilation equipment for exhausting indoor air to the outside is included.

이중에서 냉방장치는 액체가 증발할 때 주위의 열을 흡수하는 현상을 이용하여 냉방작용을 하는 것으로, 이러한 냉방작용 이외에도, 제습작용을 함께 수행한다.Among them, the cooling device uses the phenomenon of absorbing the surrounding heat when the liquid evaporates, and performs the cooling operation. In addition to the cooling operation, the cooling operation is also performed.

이러한 기능을 갖는 냉방장치는 냉매를 고온/고압의 가스형태로 압축하는 압축기와, 상기 압축기에 의해 압축된 고온/고압의 냉매를 액화시키는 응축기와, 팽창밸브에 의해 팽창된 냉매를 증발시키는 열교환기로 구성되어 있으며, 상기 열교환기를 통과하면서 열교환된 냉각공기는 블로어(송풍기)에 의해 냉방이 필요한 실내로 강제 송풍된다.A cooling device having such a function includes a compressor for compressing a refrigerant into a gas of high temperature / high pressure, a condenser for liquefying a high temperature / high pressure refrigerant compressed by the compressor, and a heat exchanger for evaporating the refrigerant expanded by an expansion valve. The cooling air heat-exchanged while passing through the said heat exchanger is forcibly blown into the room | room which needs cooling by a blower (blower).

이러한 냉방장치 중에서, 일반가정이나 음식점과 같이 냉방공간이 작은 곳에주로 설치 사용하는 패키지형 에어컨은 실외기형과 실내기형으로 분리되어 이루어져 있다. 상기 실외기형은 냉매를 압축시키는 압축기와 이를 응축시키는 응축기가 갖추어져 있으며, 이들 구동시 소음 및 열방출로 인하여 건물의 옥상이나 베란다 외부에 설치한다. 상기 실내기는 응축기에서 보내진 냉매를 증발시켜 실내로 공급하는 부분으로 실내의 한쪽 구석에 세워놓는 캐비닛형과 함께, 벽면에 걸어 놓을 수 있는 벽걸이형이 많이 사용된다.Among such cooling devices, package type air conditioners, which are mainly installed in a small cooling space such as a home or a restaurant, are divided into an outdoor type and an indoor type. The outdoor type is equipped with a compressor for compressing the refrigerant and a condenser for condensing it, and is installed outside the roof or veranda of the building due to noise and heat emission during these driving. The indoor unit is a part for supplying the refrigerant to the room by evaporating the refrigerant sent from the condenser, along with a cabinet type standing in one corner of the room, and a wall hanging type that can be hung on a wall is used.

도 1은 일반적인 벽걸이형 에어컨의 실내기(1)를 도시한 종방향 단면도이다.1 is a longitudinal sectional view showing an indoor unit 1 of a general wall-mounted air conditioner.

여기에 도시된 바와 같이, 실내기(1)를 구성하는 프론트 커버(5)와 대향으로 리어 커버(6)가 결합되어 있다. 따라서, 횡단류팬(2)의 회전에 따라 프론트 그릴(7) 및 흡입구(5a)를 통해 유입된 공기가 열교환기(3)를 지나는 과정에서 다수의 튜브(4)를 흐르고 있는 냉매와의 열교환을 통해 차갑게 냉각된 다음, 토출구(5b)를 통해서 실내로 공급된다.As shown here, the rear cover 6 is coupled to the front cover 5 constituting the indoor unit 1. Therefore, as the cross flow fan 2 rotates, the air flowing through the front grille 7 and the intake port 5a passes through the heat exchanger 3, thereby exchanging heat with the refrigerant flowing through the plurality of tubes 4. Cooled through and then supplied to the room through the discharge port (5b).

It has a cylindrical shape.

이러한 횡단류팬(2)은 단지 팬의 전장길이를 늘이는 것만으로도 그것에 비례해서 토출풍량이 같이 증가하는 장점을 가지고 있다.Such a crossflow fan 2 has the advantage that the discharge air volume increases in proportion to it even by simply increasing the overall length of the fan.

그러나, 종래의 횡단류팬(2)은 각 단(2b)들이 서로 고정된 상태로 만들어지기 때문에, 이러한 경우 길이가 다른 횡단류팬을 사용하고자 할 때 횡단류팬을 다시 만들어야 하는 단점이 있다.However, in the conventional crossflow fan 2, since the stages 2b are made fixed to each other, in this case, there is a disadvantage in that the crossflow fan needs to be made again when a crossflow fan having a different length is desired.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 횡단류팬의 각 단들이 독립적으로 형성되고, 각 단들 사이가 착탈구조로 구성되어 손쉽게 횡단류팬의 전체 전장길이를 늘이고 줄일 수 있도록 한 벽걸이형 실내기의 횡단류팬을 제공하는데 있다.The present invention has been made to solve the above problems, the object of the present invention is that each end of the crossflow fan is formed independently, and between each end is composed of a removable structure to easily increase and decrease the overall length of the crossflow fan. It is to provide a crossflow fan of a wall-mounted indoor unit.
