이하, 상기와 같이 구성된 본 발명에 따른 냉동차량의 냉동탑용 에어커튼장치의 작용을 설명한다.Hereinafter, the operation of the refrigeration tower air curtain device for a refrigerator vehicle according to the present invention configured as described above.

먼저, 냉동탑(200)의 도어(210)가 닫혔을 때는, 도어(210)와 이에 대향되게 설치된 릴레이(340)의 접촉으로 인해 시로코팬(320)의 모터(330)측으로 전원의 공급이 차단된 상태로서, 모터(330) 및 시로코팬(320)의 작동은 정지된 상태이다.First, when the door 210 of the freezing tower 200 is closed, the supply of power to the motor 330 side of the sirocco fan 320 is cut off due to the contact between the door 210 and the relay 340 installed to face the door 210. In this state, the operation of the motor 330 and the sirocco fan 320 is stopped.

이후, 냉동탑(200)에 보관된 물품을 인출하기 위해 도어(210)를 개방하면, 도어(210)가 개방됨과 동시에 이에 접촉되어 있던 릴레이(340)가 비접촉 상태가 되면서 시로코팬(320)의 모터(330)측으로 전원이 공급된다.Subsequently, when the door 210 is opened to take out the goods stored in the freezing tower 200, the door 210 is opened and the relay 340, which has been in contact with the door 210, is brought into a non-contact state, and thus, of the sirocco fan 320. Power is supplied to the motor 330 side.

그러면, 공급된 전원에 의해 모터(330)가 구동되어 시로코팬(320)이 회전되고, 시로코팬(320)의 회전에 의해 외부의 공기 즉 외기가 하우징(310)의 흡기구(311)로 흡입되어 시로코팬(320)의 양단부로 유입되면서 블레이드를 통해 하우징(310)의 배기구(312)로 토출된다.Then, the motor 330 is driven by the supplied power to rotate the sirocco fan 320, and external air, that is, outside air, is sucked into the intake port 311 of the housing 310 by the rotation of the sirocco fan 320. While entering the both ends of the sirocco fan 320 is discharged to the exhaust port 312 of the housing 310 through the blade.

따라서, 상기와 같이 토출되는 외기는 개방된 도어(210)에 의한 냉동탑(200)의 개구부상으로 집중적으로 토출되어 에어커튼을 형성하게 됨으로써 냉동탑(200)의 내부와 외부가 차단되어 냉기의 손실을 방지함으로써 냉동탑(200)의 보냉효과를 그대로 유지할 수 있게 된다.Therefore, the outside air discharged as described above is intensively discharged onto the opening of the freezing tower 200 by the open door 210 to form an air curtain, thereby blocking the inside and the outside of the freezing tower 200, By preventing the loss it is possible to maintain the cooling effect of the freezing tower 200 as it is.

이후, 개방된 도어(210)를 닫으면 릴레이(340)와 도어(210)가 접촉된 상태로서 전술한 바와 같이 모터(330)와 시로코팬(320)의 작동이 정지된다.Thereafter, when the open door 210 is closed, the operation of the motor 330 and the sirocco fan 320 is stopped as described above as the relay 340 and the door 210 are in contact with each other.

한편, 본 발명에서는 에어커튼장치(300)가 냉동탑(200)의 외부에 외장되게 설치되어, 냉동탑(200) 외부의 외기로서 에어커튼을 형성함으로써 에어커튼장치(300)를 구성하는 주요부품인 모터(330)나 시로코팬(320) 등이 외기에만 접촉되므로 인해 냉기와의 온도차로 인한 결로현상의 발생을 미연에 방지할 수 있고, 그로 인한 부식을 방지할 수 있게 된다.On the other hand, in the present invention, the air curtain device 300 is installed to be external to the outside of the freezing tower 200, the main components constituting the air curtain device 300 by forming an air curtain as the outside air outside the freezing tower 200. Since the phosphorus motor 330 or the sirocco fan 320 is only in contact with the outside air, condensation may be prevented due to a temperature difference from the cold air, thereby preventing corrosion.

즉, 에어커튼장치(300)가 냉동탑(200)내에 내장되게 되면, 도어(210)의 개방 시 에어커튼을 형성하는 에어커튼장치(300)가 냉기와 외기의 경계면상에 위치되기 때문에, 에어커튼장치(300)를 구성하는 모터(330)와 시로코팬(320), 하우징(310) 등에 냉기와 외기의 온도차로 인한 결로현상이 발생되고, 이 결로현상으로 인해 결국에는 상기의 부품들이 부식되는 치명적인 단점이 있다.That is, when the air curtain device 300 is embedded in the freezing tower 200, since the air curtain device 300 forming the air curtain when the door 210 is opened is located on the interface between the cold and the outside air, Condensation occurs due to a temperature difference between cold and outside air in the motor 330, the sirocco fan 320, and the housing 310 constituting the curtain device 300, and the condensation eventually causes corrosion of the above components. There is a fatal drawback.

따라서, 본 발명에서는 에어커튼장치(300)를 냉동탑(200)의 외부에 외장되게 설치함으로써 전술한 바와 같은 단점을 미연에 해소한 것이다.Therefore, in the present invention, by installing the air curtain device 300 to the outside of the freezing tower 200 to solve the above-mentioned disadvantages in advance.

한편, 본 발명에서는 에어커튼장치(300)와 도어(210)가 냉동탑(200)의 후면부에 형성된 것을 그 일례로 들어 설명하였지만, 이에 국한되거나 한정되지 않고 다양한 실시형태를 포함한다.Meanwhile, in the present invention, the air curtain device 300 and the door 210 are formed as an example of the rear surface of the freezing tower 200. For example, the present invention is not limited thereto and includes various embodiments.

이상에서 설명한 바와 같이, 본 발명의 냉동차량의 냉동탑용 에어커튼장치에 따르면, 냉동탑의 도어가 개방됨과 동시에 에어커튼장치가 작동되어 외기로서 에어커튼을 형성함으로써 도어의 개방 시 냉동탑의 내부와 외부를 차단시켜 냉기의 손실을 방지하여 냉동탑의 보냉효과를 유지할 수 있는 장점이 있다.As described above, according to the refrigeration tower air curtain device of the present invention, the door of the refrigeration tower is opened and at the same time the air curtain device is operated to form an air curtain as the outside air to form the interior of the refrigeration tower when the door is opened. By blocking the outside to prevent the loss of cold air has the advantage of maintaining the cooling effect of the freezing tower.
