| 摘要 |
The present invention relates to a dual-structured hidden blade fan including an air vent or a ventilator thereof and, more specifically, to a dual-structured hidden blade fan including an air vent or a ventilator thereof capable of comprising a raceway unit (100), a ventilating unit (200), a base unit (300), and a support unit (400). The raceway unit comprises an inner raceway surface, an outer raceway surface, and an air vent which penetrates the inner raceway surface and the outer raceway surface. The ventilating unit comprises a ventilating ring for circulating air and a discharge port which discharges the air to the outside. The base unit comprises a motor and a fan formed on a lower part of the raceway unit and the ventilating unit to transmit the air of the ventilating unit. The support unit is connected to the base unit to support the raceway unit. The ventilating unit which circulates and discharges the air and the raceway unit which guides the flow of a coanda surface for the discharged air have a separated dual structure and improve efficiency. The present invention is provided to increase airflow by forming a Bernoulli tube and occurring additional air. |
