According to the present invention, the inside of a body made of a non-conducting material is divided into a dehumidifying unit; an air layer consisting of a plurality of films; and a vent unit formed by a foreign substance filtering layer. Moisture in the air introduced into a housing of a device by passing through a clean air layer of which foreign substances such as water, dust, or the like are filtered in the vent unit and the dehumidifying unit is absorbed in the dehumidifying unit which is completely isolated from the outside air by a plurality of air layers, whereby the inside of the device becomes drier than the outside thereof. In addition, a grill formed with a plurality of through-holes is mounted on an end portion of the body, whereby the moisture in the inner air is directly moved to the dehumidifying unit through the through-holes formed on a front surface of the grill. When a fixing cap is coupled to the body from the outside of the housing, a moving path which communicates with a chamfered surface is formed on an outer circumferential surface of the body, whereby a flow of the air becomes smooth to improve ventilation efficiency. Accordingly, the pressure control vent for preventing condensation can make a user have improved reliability and durability with respect to a product.

    본 발명은, 비전도체 재질의 바디 내부를 제습부와 다수의 막으로 형성되는 공기층, 그리고 이물질여과막으로 형성되는 벤트부로 분할하고 벤트부에서 물, 분진 등의 이물질이 걸러진 깨끗한 공기층, 제습부를 통과하여 기기의 하우징 내부로 유입되고 유입된 공기 중의 습기는 복수의 공기층으로 외부의 공기와 완벽하게 격리된 제습부에서 습기를 흡습하여 기기 내부를 외부보다 건조한 상태로 만듬과 아울러 바디 단부에 다수의 통공이 형성된 그릴을 장착하여 그릴의 정면에 형성된 다수의 통기공을 통해 내부공기 중의 습기가 제습부로 직접 이동함은 물론 하우징 외부에서 고정캡이 바디에 체결될 때, 바디 외주면에 면취면과 연통되는 이동통로를 형성함으로써, 공기의 흐름을 원활하게 하여 통기효율을 향상시킴으로 사용자로 하여금 제품에 대한 신뢰성 및 내구성을 향상시킬 수 있는 결로방지용 압력조절 벤트에 관한 것이다.
