Description

천장 부착형 공기조화기의 실내기{In-door-unit of ceiling type air-conditioner}Indoor unit of ceiling type air conditioner {In-door-unit of ceiling type air-conditioner}

본 발명은 천장형 공기조화기에 관한 것으로서, 더 상세하게는 천장 부착형공기조화기의 실내기에 관한 것이다.The present invention relates to a ceiling type air conditioner, and more particularly, to an indoor unit of a ceiling type air conditioner.

일반적으로, 공기조화기는, 상점 및 사무실 또는 가정 등의 실내의 한 공간 또는 벽체 등에 설치하여 실내냉방 또는 실내난방을 이루도록 한 냉/난방기로서, 특히 천장형 공기조화기는 실내의 천장에 설치하여 냉방 또는 난방을 수행하도록 한 것이다.In general, an air conditioner is a cooling / heating unit installed in a space or a wall of a room, such as a store, an office, or a home, to achieve indoor cooling or room heating, and in particular, a ceiling type air conditioner is installed on a ceiling of an indoor room for cooling or It is to perform heating.

이러한 천장형 공기조화기는, 실내공간중에 활용도가 비교적 낮은 천장에 설치함으로써 벽걸이형이나 입식형 공기조화기에 비해 공간상의 제약을 덜 받는 이점과 함께, 천장으로부터 냉기가 토출되므로 냉기의 확산속도가 비교적 빠르다는 또 다른 이점으로 인해 점차 그 수요층이 확산되고 있다.The ceiling type air conditioner is installed in a ceiling of low utilization in the interior space, and has less advantage of space constraints than a wall-mounted or standing type air conditioner, and discharges cold air from the ceiling, so the diffusion rate of cold air is relatively high. Another advantage is the growing demand for it.

이하, 도 1을 참조하여, 종래기술에 따른 천장 부착형 공기조화기의 실내기 구성 및 동작을 설명한다.Hereinafter, with reference to Figure 1, the configuration and operation of the indoor unit of the ceiling-mounted air conditioner according to the prior art.

천장 부착형 공기조화기의 실내기는, 외장을 형성하며 천장에 부착되는 케이스(1)와, 상기 케이스의 내부 중앙에 하향으로 설치된 터보팬(2, turbo fan) 및 팬모터(3)와, 상기 터보팬의 주위의 사방에 설치된 열교환기(4)로 크게 이루어진다.The indoor unit of the ceiling-mounted air conditioner includes a case 1 which forms an exterior and is attached to the ceiling, a turbo fan 2 and a fan motor 3 installed downward in the inner center of the case; It consists large of the heat exchanger 4 provided in all four sides of a turbofan.

그리고, 상기 케이스(1)의 저면 중앙부에는 상기 터보팬(2)에 의해 발생한 흡입력에 의해 케이스 내로 공기가 흡입될 수 있도록 흡입구(1a)가 형성되고, 상기 케이스의 측면에는 케이스 내로 유입되어 열교환된 공기가 토출되는 토출구(1b)가 형성된다.In addition, a suction port 1a is formed at the center of the bottom surface of the case 1 so that air can be sucked into the case by the suction force generated by the turbofan 2, and the side surface of the case is introduced into the case and heat-exchanged. The discharge port 1b through which air is discharged is formed.

한편, 상기 터보팬(2)은, 팬모터(3)와 축결합되는 허브(2a)와, 상기 허브의 내측면 주위를 따라 일정간격으로 다수개 구비된 에어포일 형상의 블레이드(2b)와,상기 블레이드들의 하단을 따라 연결된 쉬라우드(2c)로 이루어진다,On the other hand, the turbo fan 2, the hub (2a) is axially coupled to the fan motor (3), a plurality of blades (2b) of the airfoil shape provided at regular intervals around the inner surface of the hub, Consisting of shrouds 2c connected along the bottom of the blades,

그리고, 상기 터보팬(2)의 허브(2a) 및 쉬라우드(2c)는 공기를 토출시키고자 하는 방향으로 자체유로를 형성하고 있으며, 상기 터보팬의 하부에는 축방향으로 외부공기를 흡입하기 위한 입구부(2d)가 형성되며, 상기 터보팬의 측면부에는 흡입된 공기가 토출되는 출구부(2e)가 형성된다.The hub 2a and the shroud 2c of the turbofan 2 form their own flow paths in a direction for discharging air, and the lower portion of the turbofan 2 is configured to suck external air in the axial direction. An inlet portion 2d is formed, and an outlet portion 2e through which the sucked air is discharged is formed in the side portion of the turbofan.

따라서, 상기 팬모터(3)의 동력발생에 의해 이에 결합된 터보팬(2)이 일방향으로 회전하게 되면 그 회전력에 의해 케이스(1)의 저면 중앙에 형성된 흡입구(1a)를 통해 실내공기가 흡입되고, 흡입된 공기는 터보팬의 입구부(2d)를 통해 블레이드(2b)를 거쳐 각 블레이드 사이의 출구부(2e)로 토출되며, 출구부로 토출된 공기는 터보팬의 주위에 설치된 열교환기(4)를 통과하게 된다.Therefore, when the turbo fan 2 coupled thereto by the power generation of the fan motor 3 rotates in one direction, the indoor air is sucked through the suction port 1a formed at the center of the bottom surface of the case 1 by the rotational force. The sucked air is discharged to the outlet portion 2e between the blades through the blade 2b through the inlet portion 2d of the turbofan, and the air discharged to the outlet portion is a heat exchanger installed around the turbofan ( Pass 4).

이와 같이 열교환기(4)를 통과하면서 열교환된 공기는 최종적으로 케이스(1)의 측면부에 형성된 토출구(1b)를 통해 기외로 배출되는 과정을 반복하면서 실내를 냉방 또는 난방시키게 된다.As such, the air heat-exchanged while passing through the heat exchanger 4 finally cools or heats the room while repeating the process of discharging to the outside through the discharge port 1b formed at the side portion of the case 1.

하지만, 상기와 같이 이루어진 종래기술에 따른 천장형 공기조화기의 실내기는, 토출구(1b)가 케이스(1)의 측면에 사방으로 형성됨에 따라, 토출되는 공기가 천장 표면으로 직접 토출되게 되어(도 1의 화살표 참조) 여러 문제가 발생되었다.However, the indoor unit of the ceiling-type air conditioner according to the prior art made as described above, as the discharge port 1b is formed on the side of the case 1 in all directions, the discharged air is discharged directly to the ceiling surface (Fig. Several problems have occurred.

첫째, 토출공기가 실내 중앙인 냉/난방 유효영역으로 토출되지 않고 천장 표면인 냉/난방 사영역으로 토출됨에 따라, 사용자가 체감할 수 있는 냉/난방감이 떨어지는 문제가 있었고, 토출공기가 천장표면에서 재차 열교환됨에 따라 기기의 냉/난방 효율이 저하되는 문제가 있었다.First, as the discharged air is not discharged to the effective cooling / heating area in the center of the room, but is discharged to the cooling / heating area on the ceiling surface, there is a problem that the cooling / heating feeling that the user can feel decreases. As the heat exchanged again on the surface, there was a problem that the cooling / heating efficiency of the device is lowered.

둘째, 토출공기가 천장표면으로 토출됨에 따라, 토출공기와 천장표면과의 온도차에 의해 천장표면에 곰팡이 등의 주원인인 응축수(일면 '이슬'이라 함)가 맺히는 문제가 있었다.Second, as the discharged air is discharged to the ceiling surface, there is a problem that condensed water (called 'dew' on one side), which is a main cause of mold, forms on the ceiling surface due to the temperature difference between the discharged air and the ceiling surface.

본 발명은 종래기술에 대한 문제점을 해결하기 위한 것으로서, 천장 부착형 공기조화기의 실내기를 개선하여, 기기의 효율을 향상시키는 한편, 천장에 응축수가 맺히는 것을 미연에 차단하는데 그 목적이 있다.The present invention is to solve the problems of the prior art, and to improve the indoor unit of the ceiling-mounted air conditioner, while improving the efficiency of the device, the purpose of preventing the condensation water condensation on the ceiling in advance.

On the outlet side of the turbofan is provided an indoor unit of the ceiling-mounted air conditioner is provided with a flow guide for guiding the air from the outlet of the turbofan to flow smoothly to the discharge port.

이 때, 상기 유동가이드는, 상기 터보팬으로부터 토출되는 공기의 유동저항을 최소화하기 위해, 상기 팬모터 축의 수직방향에서 팬모터 축 방향으로 라우드진 형상의 몸체부를 가짐이 바람직하다,At this time, the flow guide, in order to minimize the flow resistance of the air discharged from the turbo fan, it is preferable to have a body portion of a loud shape in the fan motor axis direction in the vertical direction of the fan motor shaft,

이와 더불어, 상기 유동가이드는, 상기 터보팬으로부터 토출되는 공기를 정류(整流)하기 위해, 상기 몸체부에, 상기 터보팬 출구부측의 공기유동방향으로 하향 곡선을 그리는 돌기부가 더 형성됨이 더욱 바람직하다.In addition, the flow guide, in order to rectify the air discharged from the turbo fan, it is more preferable that the projection portion that is downwardly curved in the air flow direction on the turbo fan outlet side side is further formed in the body portion. .

따라서, 본 발명에 따른 천장 부착형 공기조화기의 실내기는, 기기의 효율을 향상시킬 수 있는 한편, 천장에 응축수가 맺히는 것을 미연에 차단할 수 있게 된다.Therefore, while the indoor unit of the ceiling-mounted air conditioner according to the present invention can improve the efficiency of the device, it is possible to block condensed water from forming on the ceiling.

이하, 첨부도면을 참조하여, 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

The discharge port 10b through which air from (2e) heat-exchanges and is discharged is formed.

여기서, 상기 토출구(10b)가 상기 케이스(10)의 저면 외곽부에 형성된 이유는, 목적하는 바와 같이, 토출공기의 방향을 실내 중앙부인 냉/난방 유효영역으로 설정하여(도 2의 화살표 참조) 사용자가 체감할 수 있는 냉/난방감을 높이기 위함이고, 천장표면에 응축수(일면 '이슬'이라 함)가 맺히는 것을 차단하기 위함이다.Here, the reason why the discharge port 10b is formed in the outer periphery of the bottom surface of the case 10 is, as desired, by setting the direction of discharge air to the cooling / heating effective area that is the center of the room (see the arrow in FIG. 2). This is to increase the cooling / heating feeling that the user can feel, and to prevent condensate (called 'dew') from forming on the ceiling surface.

그리고, 상기 케이스(10)의 내벽 중 상기 터보팬의 출구부(2e)측에는 상기 터보팬의 출구부로부터 나온 공기가 상기 토출구(10b)로 원활하게 유동되도록 안내하는 유동가이드(20)가 구비되어 이루어진다.In addition, a flow guide 20 is provided at the outlet portion 2e side of the turbo fan of the inner wall of the case 10 to smoothly flow air from the outlet portion of the turbo fan to the discharge port 10b.
