일반적으로 객차(철도차량) 또는 고속버스 등의 상용차량은 고속 장거리 여행 시 주로 이용되는 대중 교통수단으로서, 많은 사람이 밀폐된 차량 내부에 장시간 승차하기 때문에 차량 내부로 원활한 공기조화가 이루어지지 않을 경우 승객들에게 큰 불편을 초래한다. 따라서 상기 상용차량의 실내공간을 가장 알맞은 온도, 습도 및 기류의 분포로 조절함과 동시에 공기 속의 이물질이나 먼지 등을 제거하기 위하여 공기청정장치를 설치하고 있음은 주지된 사실이다.In general, commercial vehicles such as passenger cars (train cars) or express buses are the public transportation used mainly for high-speed long-distance travel, and when many people ride in closed vehicles for a long time, when air conditioning is not smooth inside the vehicle. It causes great inconvenience for passengers. Therefore, it is well known that an air purifier is installed to control the indoor space of the commercial vehicle to the most suitable temperature, humidity, and air flow distribution and to remove foreign substances or dust in the air.

이와 같이 대형 상용차량에 설치하는 공기청정장치는 상용차량의 천장에 설치되도록 형성된 하우징, 상기 하우징의 저면을 커버하면서 하우징에 유입된 공기를 차량의 실내로 공급할 수 있도록 형성된 그릴커버, 상기 하우징의 양측에 설치되어 상기 롤 필터를 장착한 상태로 회전시킬 수 있도록 형성된 구동축, 상기 구동축에 장착된 롤 필터가 그릴커버에 밀착된 상태로 인출이 이루어지도록 형성된 가이드 롤러 및 상기 하우징의 상측으로 연결되어 공기를 공급하기 위한 플로우 덕트로 이루어진다.As described above, an air cleaning device installed in a large commercial vehicle includes a housing formed to be installed on a ceiling of a commercial vehicle, a grill cover formed to cover the bottom surface of the housing and supply air introduced into the housing to the interior of the vehicle, and both sides of the housing. A drive shaft installed at the roll filter to be rotated in a state where the roll filter is mounted, a guide roller formed to be drawn out in a state in which the roll filter attached to the drive shaft is in close contact with the grill cover, and connected to an upper side of the housing to supply air. It consists of a flow duct for feeding.

따라서 이와 같은 구성에 의하면 상기 플로우 덕트를 통해 공급되는 공기가 각 하우징 내부로 유입되면서 그릴커버 내측에 펼쳐진 롤 필터를 거쳐 차량 실내로 공급되는 한편, 일정 시간 사용 후에는 상기 롤 필터를 권취하여 새로운 면이 그릴 커버 상에 펼쳐지도록 한다.Therefore, according to such a configuration, while the air supplied through the flow duct is introduced into each housing, the air is supplied to the vehicle interior through a roll filter spread inside the grill cover. It is spread out on the grill cover.

그러나 이와 같은 구성에 의하면 상기 플로우 덕트가 상용차량의 여러 지점에 설치된 공기청정장치들을 연결한 상태에서 그 일 지점으로부터 각 공기청정장치로 공기를 공급하도록 형성되기 때문에 각 공기청정장치의 그릴커버를 통해 차량 실내로 유입되는 송풍압력이 저하되는 문제점이 있다.However, according to such a configuration, since the flow duct is formed to supply air to each air cleaning device from one point while connecting the air cleaning devices installed at various points of the commercial vehicle, through the grill cover of each air cleaning device. There is a problem that the blowing pressure flowing into the vehicle interior is lowered.

더구나 상기 그릴커버 내측에 펼쳐진 롤 필터 상에 걸러진 이물질의 양이 증가함에 따라 차량 실내로 공급되는 송풍압력은 더욱 저하될 것이므로 롤 필터의 권회 횟수가 증가할 수밖에 없고 이는 결국 롤 필터의 효율을 저하시키는 문제를 초래한다.In addition, as the amount of foreign matter filtered on the roll filter spread inside the grill cover increases, the blowing pressure supplied to the vehicle interior will further decrease, which inevitably increases the number of turns of the roll filter, which in turn lowers the efficiency of the roll filter. Cause problems.

본 발명은 종래 문제점 및 결점을 해결하기 위한 것으로서, 그 주된 목적으로는 객차(철도차량)이나 버스 등의 상용차량에 설치되어 실내로 공급되는 공기 중의 이물질이나 먼지 등을 제거하기 위한 롤 필터가 적용된 상용차량용 공기정화장치를 형성하되, 상기 상용차량 실내로 더욱 원활하고 강력한 정화 공기의 공급이 이루어질 수 있도록 한 롤 필터가 적용된 상용차량용 공기정화장치를 제공하려는 것이다.The present invention is to solve the problems and drawbacks of the prior art, the main purpose of which is installed in a commercial vehicle such as a passenger car (railroad vehicle) or a bus is applied a roll filter for removing foreign matter or dust in the air supplied to the room The present invention is to provide an air purifier for a commercial vehicle, but to provide an air purifier for a commercial vehicle to which a roll filter is applied so as to smoothly and powerfully supply purified air to the interior of the commercial vehicle.

이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의거 구체적으로 살펴본다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 롤 필터가 적용된 상용차량용 공기정화장치를 도시한 단면도, 도 2는 본 발명의 롤 필터가 적용된 상용차량용 공기정화장치의 일 실시예를 도시한 작용도, 도 3은 본 발명의 롤 필터가 적용된 상용차량용 공기정화장치의 다른 실시예를 도시한 작용도이다.1 is a cross-sectional view showing an air purifier for a commercial vehicle to which the roll filter of the present invention is applied, FIG. 2 is a functional view showing an embodiment of an air purifier for a commercial vehicle to which the roll filter of the present invention is applied, and FIG. Is a functional diagram showing another embodiment of an air purifier for a commercial vehicle to which the roll filter is applied.

본 발명의 상용차량의 롤 필터 장치는 도 1 내지 도 3에 도시된 바와 같이 크게 상용차량의 천장에 설치되는 하우징(10), 상기 하우징의 저면을 커버하는 그 릴커버(20), 장착된 롤 필터(50)를 회전시키기 위한 구동축(30), 인출된 롤 필터를 안내하기 위한 가이드 롤러(40), 상용차량 내부로부터 하우징 상측으로 연통된 플로우덕트(100), 상기 플로우덕트로부터 유입된 공기를 인출된 롤 필터로 강제 송풍시키기 위한 크로스팬(200) 및 일정시간 경과 후 상기 구동축을 회전시키기 위한 타이머(300)로 구성한다.Roll filter device of a commercial vehicle of the present invention is a housing 10 is installed on the ceiling of a commercial vehicle largely, as shown in Figures 1 to 3, the grill cover 20 to cover the bottom of the housing, the roll mounted The drive shaft 30 for rotating the filter 50, the guide roller 40 for guiding the drawn roll filter, the flow duct 100 communicated from the inside of the commercial vehicle to the housing upper side, and the air introduced from the flow duct Cross fan 200 for forcibly blowing with the drawn roll filter and a timer 300 for rotating the drive shaft after a predetermined time.

이에, 상기 하우징(10)은 상용차량의 천장에 설치되는 것으로서 롤 필터(50)가 펼쳐진 상태로 외부공기의 유입과 롤 필터(50)를 통해 정화 공기의 배출이 원활하게 이루어질 수 있는 크기로 형성한다. 이때, 상기 하우징(10)의 내부 양측에는 상기 구동축(30)에 장착되는 롤 필터(50)를 보호하기 위해 별도의 구획공간을 형성한다.Thus, the housing 10 is installed on the ceiling of a commercial vehicle, and formed to a size that allows the inflow of external air and the purge air to be discharged smoothly through the roll filter 50 while the roll filter 50 is unfolded. do. In this case, separate partition spaces are formed on both sides of the housing 10 to protect the roll filter 50 mounted on the drive shaft 30.

상기 그릴커버(20)는 상기 하우징(10)의 저면을 커버하면서 하우징(10)에 유입된 공기를 차량 실내로 공급할 수 있도록 형성한다. 한편, 상기 그릴커버(20)는 다수개의 통공을 갖는 판 형태로서 형성되면서 하우징(10)의 저면을 개폐 가능하도록 형성한다.The grill cover 20 is formed to cover the bottom of the housing 10 to supply the air introduced into the housing 10 to the vehicle interior. On the other hand, the grill cover 20 is formed in the form of a plate having a plurality of through holes to form the bottom of the housing 10 to be opened and closed.

상기 구동축(30)은 상기 하우징(10)의 양측에 설치되어 상기 롤 필터(50)를 장착한 상태로 회전시킬 수 있도록 형성한다. 따라서 상기 구동축(30)에는 상기 롤 필터(50)를 회전시키기 위한 전동모터(미도시)를 결합하여 운전자의 조작에 의해서 회전이 이루어지도록 한다. 이때, 상기 구동축(30)에 의해 회전되는 롤 필터(50)는 타측에 권취된 롤 필터(50)의 새로운 면을 그릴커버(20) 상에 펼침으로써 원활한 공기정화가 이루어지도록 한다.The drive shaft 30 is installed on both sides of the housing 10 so as to rotate in a state where the roll filter 50 is mounted. Therefore, the drive shaft 30 is coupled to an electric motor (not shown) for rotating the roll filter 50 to be rotated by a driver's operation. At this time, the roll filter 50 rotated by the drive shaft 30 spreads a new surface of the roll filter 50 wound on the other side on the grill cover 20 to achieve a smooth air purification.

한편, 상기 전동모터(미도시)와 타이머(300)를 연결함으로써 롤 필터(50)가 펼쳐진 상태에서 일정시간 사용 후 자동으로 구동축(30)을 회전시킬 수 있도록 함이 바람직하다. 즉, 상기 타이머(300)에 의해 설정된 시간 동안 전동모터가 정지된 상태로 그릴커버(20) 상에 펼쳐진 롤 필터(50)를 통해 실내 공기의 정화가 이루어지며, 설정된 시간의 경과 후에는 상기 전동모터를 회전시켜 롤 필터(50)의 새로운 면이 그릴커버(20) 상에 펼쳐지도록 한다. 물론, 상기 타이머(300)에 의해 작동하는 전동모터는 구동축(30)을 회전시킴으로써 양측 롤 필터(50)의 권취가 이루어진다.On the other hand, by connecting the electric motor (not shown) and the timer 300, it is preferable to automatically rotate the drive shaft 30 after a predetermined time in the roll filter 50 unfolded state. That is, the indoor air is purged through the roll filter 50 spread on the grill cover 20 while the electric motor is stopped for the time set by the timer 300. Rotating the motor allows a new face of the roll filter 50 to be unfolded on the grill cover 20. Of course, the electric motor operated by the timer 300 is wound around the roll filter 50 by rotating the drive shaft (30).

상기 가이드 롤러(40)는 상기 구동축(30)에 장착된 롤 필터(50)가 그릴커버(20)에 밀착된 상태로 원활한 인출을 안내하도록 형성한다. 즉, 상기 가이드 롤러(40)는 구동축(30) 하측에 형성하면서 상기 그릴커버(20)로부터 미세한 높이에 형성함으로써 구동축(30)으로부터 풀리는 롤 필터(50)를 그릴커버 상에 근접된 상태로 안내한다.The guide roller 40 is formed so that the roll filter 50 mounted on the drive shaft 30 guides the smooth withdrawal while being in close contact with the grill cover 20. That is, the guide roller 40 is formed below the drive shaft 30 at a fine height from the grill cover 20, thereby guiding the roll filter 50 released from the drive shaft 30 in a state close to the grill cover. do.

이와 같은 구성에 있어서 상기 플로우덕트(100)는 상용차량 실내에 순환하는 공기를 흡입하도록 형성되면서 상기 하우징(10)의 상측으로 각각 연통되도록 형성한다. 즉, 각각의 플러우덕트(100)를 통해 상용차량 실내의 공기를 흡입한 후 롤 필터(50)로 안내하도록 형성한다. 따라서 차량 실내의 공기를 재순환시키면서 오염물질을 정화하는 구조를 통해 항상 깨끗한 실내 공기를 유지할 수 있다.In such a configuration, the flow duct 100 is formed to suck air circulating in a commercial vehicle interior, and is formed to communicate with the upper side of the housing 10, respectively. That is, the air is sucked into the commercial vehicle through each plow duct 100 and then formed to guide the roll filter 50. Therefore, the clean air is always maintained through the structure that purifies the pollutants while recirculating the air in the vehicle interior.

또한, 상기 크로스팬(200)은 상기 플로우덕트(100)를 통해 흡입된 공기를 하우징(10) 내부의 롤 필터(50)로 강재 순환시켜 정화된 공기를 차량 내부로 재공급 하도록 형성한다. 이때, 상기 크로스팬(200)을 커버하는 케이스는 플로우덕트(100) 방향과 하우징(10) 방향에 각각 통풍 출입구를 형성한다.In addition, the cross fan 200 is formed to circulate the steel sucked through the flow duct 100 to the roll filter 50 inside the housing 10 to supply the purified air to the inside of the vehicle. In this case, the case covering the cross fan 200 forms a ventilation inlet in the flow duct 100 direction and the housing 10 direction, respectively.

따라서 이와 같은 구성에 의하면 상기 그릴커버(20) 상에 펼쳐진 롤 필터(50)와 더욱 근접된 크로스팬(200)에 의해 강제로 송풍이 이루어지기 때문에 상용차량의 실내로 정화공기의 공급이 더욱 원활해지는 것은 물론이고, 크로스팬(200)을 이용하여 더욱 강한 송풍압력을 유지할 수 있으므로 그만큼 인출된 롤 필터(50)의 사용수명을 증가시킬 수 있게 된다.Therefore, according to such a configuration, since the blowing is forced by the cross fan 200 which is closer to the roll filter 50 spread on the grill cover 20, the supply of purified air to the interior of a commercial vehicle is more smooth. Of course, since it is possible to maintain a stronger blowing pressure using the cross fan 200, it is possible to increase the service life of the roll filter 50 drawn out accordingly.

더욱이 상기 플로우턱트(100)를 통해 상용차량 내부의 공기를 리턴 순환시킴으로써 실내의 공기를 더욱 깨끗하게 정화시켜 쾌적한 공간을 제공할 수 있게 된다.Furthermore, by returning and circulating the air inside the commercial vehicle through the flow duct 100, the indoor air can be more cleanly purified to provide a comfortable space.

한편, 상기 크로스팬(200)은 도 3에 도시된 바와 같이 정 역회전을 변경하여 그릴커버(20)를 통해 상용차량의 실내 공기를 흡입하면서 롤 필터(50)를 통한 공기의 정화가 이루어지도록 형성할 수도 있다.On the other hand, the cross fan 200, as shown in Figure 3 by changing the forward and reverse rotation to suck the indoor air of the commercial vehicle through the grill cover 20 to purify the air through the roll filter (50) It may be formed.
