Description

냉각 기능을 갖는 휴대용 손 선풍기{Portable Bladeless Electric Hand Fan With cooling function}Portable hand fan with cooling function {Portable Bladeless Electric Hand Fan With cooling function}

본 발명은 냉각 기능을 갖는 휴대용 손 선풍기에 관한 것으로, 보다 상세하게는, 공기의 토출시 저온의 냉풍을 발생시킬 수 있는 냉각 기능을 갖는 휴대용 손 선풍기에 관한 것이다.The present invention relates to a portable hand fan having a cooling function, and more particularly, to a portable hand fan having a cooling function capable of generating low-temperature cold air when air is discharged.

일반적으로, 선풍기는 모터 구동에 의해서 복수 개로 이루어지는 휀이 축회전되도록 하여 일방향으로 바람이 발생되도록 하는 기기이다.In general, an electric fan is a device that generates wind in one direction by rotating a plurality of fans by driving a motor.

다시 말해 선풍기는 흔히 모터를 구동시켜 선풍기 날개라고 하는 휀을 축회전시키도록 함으로써 이때 발생되는 공기의 유동에 의해서 바람이 발생되도록 하는 것입니다.In other words, a fan often drives a motor to rotate a fan, called a fan blade, so that wind is generated by the flow of air generated at this time.

다만, 최근에는 외부에 보이는 휀을 제거하고, 내부에서 모터의 구동에 의해 회전하는 임펠러에 의해 발생되는 공기가 내부 통로와 마우스부 및 코안다 표면을 통해 배출되는 코안다 효과에 의해 증폭되도록 하는 무블레이드형 선풍기가 소개된 바 있다.However, in recent years, the fan that is visible from the outside has been removed, and the air generated by the impeller rotating by the drive of the motor inside is amplified by the Coanda effect discharged through the inner passage, the mouth part, and the Coanda surface. A blade-type fan has been introduced.

즉, 무블레이드형 선풍기는 눈에 보이는 휀이 사라지면서 초기에는 획기적인 형상 때문에 대단한 호기심을 유발하기도 하고, 예상외로 강력한 바람을 생성하게 됨으로써 안전성과 효율성으로 인하여 대폭적인 관심의 대상이 되기도 하였다.In other words, as the visible fan disappeared, the bladeless fan aroused great curiosity in the early days because of its innovative shape, and also became the subject of great interest due to its safety and efficiency by generating unexpectedly strong wind.

한편, 최근 가장 이슈가 되었던 선풍기는 휴대용 선풍기이다. 이러한 휴대용 선풍기는 배터리 전원을 이용하여 휀을 회전시켜 바람이 발생되도록 하는 것은 일반 선풍기와 동일하나 사이즈가 대폭적으로 축소되도록 하면서 손잡이가 형성되도록 하는 것이다.On the other hand, the fan that has recently become the most issue is a portable fan. Such a portable electric fan rotates a fan using battery power to generate wind, which is the same as a general electric fan, but is significantly reduced in size and has a handle.

특히, 휴대용 선풍기에도 무블레이드 방식이 적용되면서 손잡이 부위를 통해 유입되는 공기를 원형의 노즐을 통해 토출되도록 하여 바람이 생성되도록 하고 있다.In particular, while the bladeless method is applied to a portable fan, air introduced through a handle is discharged through a circular nozzle to generate wind.

그러나, 종래의 무블레이드 방식의 휴대용 선풍기는 단순히 휀을 회전시켜 원형의 노즐을 통해 공기를 토출시키기 때문에 무더운 날에는 크게 효과를 낼 수 없는 구조적인 문제점이 있다.However, the conventional bladeless type portable fan simply rotates a fan to discharge air through a circular nozzle, so there is a structural problem in that it cannot be significantly effective on hot days.
