Description

Embedded fog reduction device {EMBEDDED FOG REDUCING APPARATUS}

The present invention relates to a fog reduction device for reducing fog in the air, and more particularly, to a buried type fog reduction device that is buried underground such as a road to efficiently reduce fog existing on a road.

Fog is a kind of cloud that is created near the earth's surface, and usually refers to a visible distance of 1 km or less. Fog is also classified into radiation fog, advection fog, rolling fog, and steam fog depending on the cause of its formation. These fogs are basically high-humidity, thick air meets cold air, or other causes such as thermal radiation or expansion. It forms when the temperature of the air is rapidly lowered below the dew point.

Fog, by itself, greatly reduces the visibility of humans. In particular, fog is mainly generated at dawn before the sun rises, and diffusely reflects light projected from a light source such as a car headlight to disturb the view, so it has a significant negative impact on the operation of cars and aircraft.

A driving unit is provided, and a temperature sensor, a humidity sensor, and a fog detection sensor for detecting fog may be provided as needed. Here, as the fog detection sensor, an optical sensor can be preferably employed.

The fog reduction device is selectively operated when fog is generated or there is a risk of fog occurring around where the device is installed. The operation of the fog reduction device is executed by driving control of the controller. The control device executes and controls the operation of the fog reduction device according to a control command from a manager through a communication unit. In another preferred embodiment of the present invention, the control device drives and controls the fog reduction device by determining whether or not fog is generated by itself.

When the fog reduction device is driven, the blowing fan 174 and the thermoelectric member 15 are operated. When the blowing fan 174 is driven, the gap X between the flange 12 and the first cover 21, the space between the body 10 and the blowing pipe 17, and the flow hole 171 at the bottom of the blowing pipe 17 ), the air flow is generated through the internal space of the blower pipe 17, the ventilation hole 211 of the first cover 21 and the ventilation hole 221 of the second cover 22. At this time, the direction in which the air circulates is set by the rotation direction of the blowing fan 174. The direction of rotation of the blower fan 174 will be appropriately set according to the installation location of the fog reduction device or the fog generation situation. The generation of fog and its amount are determined by the temperature of the air and the amount of water vapor. In general, when air in which water vapor is unsaturated is cooled below the dew point, the water vapor is saturated and condensation starts to form fog. As the amount of water vapor in the air increases, the dew point temperature increases, so that fog is generated even at relatively high temperatures, and when the amount of water vapor in the air is low, fog does not occur even at relatively low temperatures. In order to effectively remove or reduce fog, a method of lowering the amount of water vapor in the air or raising the temperature of the air may be considered.

The fog reduction device is provided with a thermoelectric member 15 in a circulation path of air circulated therein. The thermoelectric member 15 can function as a heating element or a cooling element by controlling the direction of the supplied current. Preferably, the control device may appropriately control the operation of the thermoelectric member 15 by determining fog generation conditions based on detection results by the temperature sensor and the humidity sensor. For example, if fog is not currently generated but there is a possibility of fog, the amount of water vapor in the air can be reduced by supercooling the circulating air and condensing the water vapor in the air into water. In addition, once the fog is generated, it may be effective to make the air non-saturated by heating the temperature of the circulated air to a temperature equal to or higher than the dew point.

When fog is generated, the fog reducing device removes or reduces the fog by inhaling and heating the air containing the fog to raise the temperature of the air above the dew point temperature. In addition, when the fog reduction device is operated, the air introduced into the main body 1 is heated by the thermoelectric member 15 and discharged to the outside. At this time, the air discharged from the fog reduction device raises the temperature of the air adjacent to the road. As a result, it provides an effect of suppressing the occurrence of fog along with additional fog removal.

In the above, embodiments according to the present invention have been described. However, the present invention is not limited to the above-described embodiment. The present invention can be practiced with various modifications within a range that does not deviate from its technical spirit.

For example, the configuration of the lid portion 2 in the above embodiment is not specified. If the fog reduction device is installed in a place where rainwater or the like does not flow, the cover part 2 may be composed of only the first cover 21.

In addition, a filter may be provided on the upper part of the body 10 and the upper part of the blower pipe 17 to block air and dust introduced from the outside.
