본 고안은 송풍기의 증발기(Evaporator)를 이용한 소형 버스용 냉방장치에 관한 것이다.The present invention relates to a small bus air conditioner using an evaporator of a blower.

통상 소형버스 즉 미니버스의 냉방기구(이하 쿨링 유닛트라 한다.)는 차체의 높이상 뒷좌석 상부에 버스의 길이방향과 직각으로 설치되는데 케이스의 흡입구쪽에 송풍기가 위치하고 냉풍 분출 닥트의 분출구 상에 증발기가 설치됨으로써 증발기의 효율을 높이기 위해서는 증발기 전면에 흡입공기를 골고루 분산통과 시켜야 하므로 송풍기와 증발기와의 거리는 어느 일정한계 이하로 좁힐 수 없어 전체적인 길이가 길어져서 버스 차체 후부의 분출 닥트 내로 장설시키지 못하고 부득이 천장 윗쪽으로 수납부를 돌출 형성시켜야 하고, 전체 길이상 뒷좌석 상부의 머리 공간부에 까지 침해하는 것을 막을 수 없었다.In general, the cooling mechanism (hereinafter referred to as cooling unit) of a minibus, or minibus, is installed at the top of the rear seat at the height of the body at right angles to the longitudinal direction of the bus. An air blower is located at the inlet of the case and an evaporator is provided at the outlet of the cold air blowing duct. In order to increase the efficiency of the evaporator, the suction air must be evenly distributed through the front of the evaporator. Therefore, the distance between the blower and the evaporator cannot be narrowed below a certain level. It was necessary to protrude the housing upwards, and it could not be prevented from invading the head space above the rear seat over the entire length.

본 고안은 이러한 종래 것의 문제점을 개선키 위해 안출한 것으로써, 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention has been devised to improve the problems of the conventional one, which will be described in detail based on the accompanying drawings.

제1도는 쿨링 유닛트(1)를 버스차체(B) 뒤쪽 상부의 냉풍 분출닥트(D)내에 설치한 사시도를 표시하는 것으로 냉풍분출닥트(D)는 차체(B)의 길이방향에 직각으로 설치되고 다수의 분출구(D')가 형성되어 이를 통해 차실내에 냉풍이 분출된다.1 shows a perspective view of the cooling unit 1 installed in the cold air blowing duct D on the upper rear side of the bus body B. The cold air blowing duct D is installed at right angles to the longitudinal direction of the car body B. A plurality of blowing holes (D ') are formed through which cold air is blown out in the vehicle interior.

제2도에 표시한 쿨링 유닛트(1)내에는 송풍기(2)가 분출닥트(D)의 분출구(D')상에, 증발기(3)는 흡입구(4)의 후면에 설치되어 송풍기(2)의 회전에 의해 차실내의 공기가 흡입구(4)를 통해 흡입되며 이때 쿨링 유닛트(1)내의 압력과 차실내의 압력차에 의해 흡입구(4)후면에 설치된 증발기(3)를 전면적으로 통과하면서 공기는 열교환 되어 냉풍이 되고 송풍기(2)의 축공(2')으로 흡입되어 분출구(D')를 통해 차실내로 분출된다.In the cooling unit 1 shown in FIG. 2, the blower 2 is installed on the ejection opening D 'of the ejecting duct D, and the evaporator 3 is provided at the rear of the inlet 4, and the blower 2 is provided. Air in the compartment is sucked through the inlet 4 by the rotation of the air, and at this time, the air in the cooling unit 1 and the pressure difference in the compartment are completely passed through the evaporator 3 installed at the rear of the inlet 4. The heat exchanged to become cold air is sucked into the shaft hole (2 ') of the blower (2) and is blown into the vehicle interior through the blower opening (D').

이와 같이 송풍기(2)를 분출닥트(D)의 분출구(D')상에 설치하고 증발기(3)를 흡입구(4)쪽에 설치하여 공기를 정압(Static Pressure) 상태로 흡입함으로써 증발기와 송풍기와의 간격을 극소화하여도 흡입공기는 압력차에 의해 증발기를 전면적으로 고르게 분포되어 증발기 효율이 저하되지 않으므로 전체적인 길이가 짧아져 쿨링 유니트(1)를 분출닥트(D)내에 장설할 수 있게 된 것이다. 부호 5는 증발기(3)의 아래에 고이는 응축수를 배수시키는 배수통이며, 응축수가 통내에 수압에 의해 배수관(5')을 통해 원활하게 배수된다.In this way, the blower 2 is installed on the ejection opening D 'of the ejection duct D, and the evaporator 3 is installed at the inlet 4, so that the air is sucked in a static pressure state. Even if the gap is minimized, the intake air is evenly distributed throughout the evaporator due to the pressure difference, so that the overall evaporator efficiency is not reduced, so that the cooling unit 1 can be installed in the blowing duct D. Reference numeral 5 denotes a drain container for draining condensate accumulated under the evaporator 3, and the condensate is smoothly drained through the drain pipe 5 'by water pressure in the tank.

이상에서와 같이 본 고안은 증발기와 송풍기간의 거리를 최소한으로 극소화함으로써 차체 후부의 분출닥트 내에 장설하여 버스차체 천장의 도출부가 전혀 없고 뒷좌석 상부의 머리 공간부를 전혀 침해하지 않는 효과가 있다.As described above, the present invention minimizes the distance between the evaporator and the blowing period, thereby installing in the blowout duct at the rear of the vehicle body, and thus has no effect of inducing the bus body ceiling at all and not invading the head space of the rear seat at all.
