Description
본 발명은 냉풍기에 관한 것이다. 특히, 흡·토출방향이 전면개선된 것과, 송풍팬으로서 2중 축류팬을 적용한 것과, 공기유도관을 나팔관 형상으로 하되 공기유도관의 출구측에 열교환 증폭부를 두어 열교환효율을 극대화한 것에 주요한 특징을 갖는다.The present invention relates to a cold fan. In particular, the main feature is that the intake and discharge direction is improved in front, the double axial flow fan is applied as a blower fan, and the air induction pipe is shaped like a trumpet tube, but the heat exchange amplification part is placed on the outlet side of the air induction pipe to maximize the heat exchange efficiency. Has
냉풍기는 에어컨과 선풍기의 틈새상품으로서 더운 실내공기를 냉매와의 열교환을 통해 저온화하여 실내로 환원되게 하는 강제대류 원리, 즉 에어컨의 원리가 이용되고 있다.Cold air conditioner is a niche product of air conditioner and fan, the forced convection principle, that is, the principle of air conditioner is used to reduce the temperature of the hot air through the heat exchange with the refrigerant to the room.
이러한 냉풍기는 제품별로 구조상 미차는 있으나 근간에 출시되고 있는 대부분의 냉풍기는 축류팬에 비해 송풍효율이 우수하다고 알려진 횡류팬이 적용되고 있어 비용상승의 요인이 된다.These cold winders are different in terms of their structure, but most of the cold winders that have been released in recent years have been applied with a crossflow fan which is known to have superior blowing efficiency compared to the axial fan.
또한, 기존 냉풍기는 공기흡입구를 전방 혹은 후방에 두고 냉기토출구는 대부분 전방에 위치하는 일률적인 형태를 취하고 있어 냉기토출구 앞에 위치하고 있는 사용자에게만 냉기가 집중되고 냉풍기의 측방 및 후방에 위치하는 사용자에게는 냉기가 송풍되지 않기 때문에 냉기 송풍범위가 극히 제한적이다.In addition, the existing cold fan has an air inlet in the front or rear, and the cold air outlet has a uniform shape, which is mostly located in front of the cold air is concentrated only to the user located in front of the cold air outlet, cold air to the user located on the side and rear of the cold air Since it is not blown, the cold air blowing range is extremely limited.
또한, 가장 큰 문제점으로 지적되는 부분중의 하나가 바로 냉방효율 문제를 들 수 있다. 냉풍기의 냉매로 사용되고 있는 얼음 및 냉수의 자체온도가 초저온이 아니기 때문에 이에 의해 열교환되는 실내공기의 온도도 그리 낮다고 볼 수 없다. 게다가 열손실을 감안한다면 100% 완전 열교환은 불가능하기 때문에 실제 열교환 된 냉풍온도는 혹서기인 경우 아무리 낮게 잡아도 20℃이하로 내려가기 어려우며, 특히 종래의 열교환 구조를 보면 열손실분이 많아 냉풍온도를 낮은 상태로 유지하기 어렵고, 이로인해 냉방효율이 극히 떨어지는 취약성을 면치 못하고 있다.In addition, one of the biggest problems is the cooling efficiency problem. Since the temperatures of ice and cold water, which are used as coolant coolers, are not ultra low temperatures, the temperatures of indoor air heat exchanged by them are not very low. In addition, 100% full heat exchange is impossible considering the heat loss, so the cold air temperature actually heat-exchanged cannot be lowered below 20 ° C even if the temperature is too low, especially in the conventional heat exchange structure, there is a large amount of heat loss. It is difficult to maintain, which is why the cooling efficiency is extremely weak.
이를 보다 구체적으로 설명하기 위해 한 예를 들고자 한다. 도 1을 보면, 냉풍기의 전면패널(1)의 하부에 공기흡입구(2)가 위치하고, 전면패널의 상부에 냉기토출구(3)가 위치하고 있으며, 전면패널의 안쪽으로 횡류형 송풍팬(4)과, 이 송풍팬의 후방으로 얼음팩(5)이 설치된 구성을 이루고 있다.To illustrate this in more detail, I will give an example. 1, the air intake opening 2 is located at the lower part of the front panel 1 of the cold air blower, and the cold air outlet 3 is located at the upper part of the front panel. And the ice pack 5 is installed in the rear of the blowing fan.
이 구조에 있어서, 전면패널(1)과 송풍팬(4) 사이의 영역은 실내공기가 그대로 정체되어 있거나 또는 열교환된 공기가 원활히 토출되지 못하고 정체되어 있는 이른 바 데드죤(dead zone)이 된다. 따라서, 데드죤에 있던 공기가 토출되는 열교환된 공기가 섞인 상태로 토출되면 냉풍온도가 현저히 올라갈 수 밖에 없기 때문에 냉풍성능 향상에 도움이 되지 않는다.In this structure, the area between the front panel 1 and the blowing fan 4 becomes a so-called dead zone where the indoor air is stagnant or the heat-exchanged air is not discharged smoothly and is stagnant. Therefore, when the air discharged in the dead zone is discharged in a state in which heat-exchanged air is mixed, the cold air temperature is inevitably increased, which does not help to improve the cold wind performance.
따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출한 것으로서, 본 발명의 제 1목적은 냉기의 흡입 및 토출방식을 전면 개선하여 냉풍기 자체를 회전시키기 않더라도 여러 사람에게 냉풍이 송풍될 수 있게 한 것에 특징을 갖는 냉풍기를 제공하는데 있다.Therefore, the present invention has been made to solve the above-mentioned conventional problems, the first object of the present invention is to improve the suction and discharge method of the cold air to the whole can be blown cold air even without rotating the cold air itself.

한편, 상기 공기유도관(30)은 상기 본체(10)의 상부에 기립상태로 설치된다. 또한 이 공기유도관은 열전도도가 큰 알루미늄으로 되며, 상부는 넓고 하부는 좁은 나팔관 형상으로 된다. 이때, 상부와 하부는 각각 공기흡입구(31)와 공기배출구(32)가 되되, 공기흡입구(31)에는 큰 이물질의 유입을 차단하기 위해 그릴 또는 루버(33)를 설치하는 것이 바람직하며, 또 유입되는 공기중의 미세한 이물질을 여과하기 위해 에어필터(80)를 설치하는 것이 보다 바람직하다.On the other hand, the air induction pipe 30 is installed in a standing state on the upper portion of the main body (10). In addition, the air induction pipe is made of aluminum with high thermal conductivity, and the upper part is wide and the lower part is a narrow fallopian tube.

미 설명부호 90은 전원의 온/오프, 송풍팬(50)의 회전속도 등을 제어하기 위한 제어패널이다.Reference numeral 90 is a control panel for controlling the on / off of the power supply, the rotational speed of the blowing fan 50, and the like.
이상의 구성을 갖는 냉풍기의 동작과정을 설명하면 다음과 같다.Referring to the operation of the cold air fan having the above configuration is as follows.
먼저, 냉매통(40)에 얼음 또는 찬물을 채워 넣어 공기유도관(30)에 내장한 상태로 부터 제어패널(90)을 조작하여 전원을 온 하면 송풍팬(50)이 팬모터(54)에 의해 일방향으로 회전된다. 송풍팬(50)의 회전력, 특히 중앙의 풀러팬(52)의 회전력에 의해 실내공기가 공기유도관(30)의 공기흡입구(31)를 통해 유입되어 아래의 공기배출구(32)를 통해 배출된다.First, when the power is turned on by operating the control panel 90 from the state filled with ice or cold water in the coolant container 40 and embedded in the air induction pipe 30, the blower fan 50 is connected to the fan motor 54. By rotating in one direction. By the rotational force of the blower fan 50, in particular, the rotational force of the central puller fan 52, the indoor air is introduced through the air inlet 31 of the air induction pipe 30 and discharged through the air outlet 32 below. .
이때, 실내공기가 유도되는 과정에서 공기유도관(30)의 형상이 나팔관 형상을 이루고 있기 때문에 하부로 갈수록 유속이 빨라지면서 공기의 원활한 흡입을 가능케하며, 유입되는 공기는 차가운 상태의 냉매통(40)과 접촉되면서 저온으로 열교환되고, 배출과정에서 열교환 증폭부(36)인 허니컴 형상에 의해 열교환 면적이 증대되면서 보다 저온화 된다.At this time, since the shape of the air induction pipe 30 forms the shape of the fallopian tube in the process of inducing indoor air, the flow velocity becomes faster toward the lower portion to enable the smooth intake of the air, and the inlet air is a coolant container in the cold state (40). Heat exchange at low temperature as it is in contact with the heat exchanger, and the heat exchange area is increased due to the honeycomb shape of the heat exchange amplifying unit 36 in the discharge process.
아울러, 공기유도관(30)은 외부와 밀폐된 형태를 취하고 있기 때문에 직접적인 열손실을 최소화하므로써 최종 공기유도관(30)으로부터 배출되어져 나온 공기는 거의 냉매온도와 유사한 온도까지 내려간 냉기로 변온되어 배출되는 것이다.In addition, since the air induction pipe 30 has a sealed shape with the outside, the air discharged from the final air induction pipe 30 is minimized by direct heat loss, and is converted into a cold temperature that is lowered to a temperature substantially similar to the refrigerant temperature.

상기 공기유도관(30)으로부터 배출되는 냉기는 송풍팬(50)의 푸셔팬(53)의 회전력에 의해 유선형으로 된 상측 바닥판(22)에 의해 가이드 되면서 하우징(20)의 상부에 마련된 냉기토출구(21)를 통해 실내로 토출된다. The cold air discharged from the air induction pipe 30 is guided by the upper bottom plate 22 which is streamlined by the rotational force of the pusher fan 53 of the blower fan 50, and is provided at the upper portion of the housing 20. It is discharged to the room through 21.
상기 냉기토출구(21)는 사방으로 개방되어 있기 때문에 냉풍기 주변의 모든 사람에게 골고루 송풍할 수 있어 냉방범위를 보다 넓히는 효과를 볼 수 있다.Since the cold air outlet 21 is open in all directions, the cold air outlet 21 can be evenly blown to all the people around the cold winder, thereby increasing the cooling range.
한편, 상기 냉매통(40)의 표면에는 상대적으로 고온인 실내공기와의 열교환에 의해 그 표면에 응축수가 발생하게 되는데, 이 응축수는 하우징(20)의 상층 바닥판(22)에 형성된 배수공(22a)를 통해 배수되며, 배수되는 응축수는 배수공(22a)의 바로 밑에 위치하고 있는 응축수 받이(60)에 집수된다. 응축수가 만수되면 응축수 받이를 하우징으로부터 탈거시켜 응축수를 버린 후 다시 장착하여 사용하게 된다.Meanwhile, condensed water is generated on the surface of the refrigerant cylinder 40 by heat exchange with indoor air, which is relatively high temperature, and the condensed water is formed in the drain plate 22a formed in the upper bottom plate 22 of the housing 20. Drained through the), the condensate is drained is collected in the condensate receiver 60 is located directly below the drain hole (22a). When the condensate is full, the condensate tray is removed from the housing to discard the condensate and then remounted.
이때, 응축수의 수위를 육안으로 볼 수 있도록 응축수 받이(60)는 투명소재로 하고, 또 하우징(20)의 응축수 받이 설치부위에는 투명창(미도시)을 마련하는 것이 바람직하다.At this time, it is preferable that the condensate receiver 60 is made of a transparent material so that the water level of the condensate can be seen with the naked eye, and a transparent window (not shown) is provided at the installation site of the condensate receiver of the housing 20.
이상에서 기술된 바와 같이 본 발명의 냉풍기는 공기흡입구의 상측에 위치하므로써 더운 공기의 흡입을 유도할 수 있어 보다 효율적인 냉방효과를 얻을 수 있을 뿐만 아니라 냉풍이 사방으로 토출되므로써 주변 여러 사람에게 골고루 냉풍을 송풍할 수 있어 냉방범위가 넓다.As described above, since the cooler of the present invention is located above the air inlet, it is possible to induce hot air intake, thereby obtaining a more efficient cooling effect, and by discharging the cold air in all directions, evenly spreading the cold air to several people around. Ventilation is possible, and the cooling range is wide.
또한, 횡류팬에 비해 저가인 축류팬을 사용하고도 원활한 흡·배출이 가능하여 경제적이다.In addition, it is economical because smooth suction and discharge are possible even when a low-cost axial fan is used compared to the crossflow fan.
또한, 공기유도관이 외부와 차단된 밀폐형이기 때문에 그 내부를 통과하는 냉기와 실내공기(외기)와의 열접촉을 최대한 차단되게 하므로써 열손실을 최소화한 점과 공기유도관의 공기배출구측에 마련된 열교환 증폭부에 의해 열교환 면적을 보다 확충한 하므로써 열교환효율을 배가시킨 점에 장점이 있다.In addition, since the air induction pipe is a sealed type that is blocked from the outside, the heat contact between the cold air passing through the inside and the indoor air (outside air) is blocked as much as possible, thereby minimizing heat loss and the heat exchanger provided at the air outlet side of the air induction pipe. There is an advantage in that the heat exchange efficiency is doubled by increasing the heat exchange area by the amplifier.
