Description

선풍기fan
본 발명은 선풍기에 관한 것으로서, 더욱 상세하게는 복수의 회전날개를 선분을 갖는 다각형의 케이스 테두리에 배치하여 공기 유입량 대비 토출량의 유속을 가속화시켜 바람의 세기를 증가시키는 선풍기에 관한 것이다.The present invention relates to a fan, and more particularly, to a fan for arranging a plurality of rotary blades on a polygonal case frame having line segments to accelerate the flow rate of the discharge amount relative to the air inflow rate to increase the wind strength.
종래의 가정용 선풍기는 통상적으로 축을 중심으로 회전하도록 탑재된 날개 또는 베인(vane)의 세트 및 이러한 날개 세트를 회전시켜 공기 흐름을 생성하는 구동 장치를 포함한다. 공기 흐름의 이동 및 순환에 의해 "풍냉(wind chill)" 또는 미풍이 발생되며, 그 결과 대류 및 증발을 통해 열이 발산됨에 따라 사용자는 냉각 효과를 체험하게 된다.Conventional household fans typically comprise a set of vanes or vanes mounted to rotate about an axis and a drive that rotates the vane sets to create airflow. The movement and circulation of the air stream creates a "wind chill" or breezy, with the result that the user experiences a cooling effect as heat is dissipated through convection and evaporation.
이러한 선풍기는 다양한 크기와 형태로 이용 가능하다. 예컨대, 천장형 선풍기의 경우에는 직경이 1 m 이상인 것도 있으며, 일반적으로 실내를 냉각시키기 위해 하방향의 공기 흐름을 제공하도록 천장에 현수되는 방식으로 장착된다. 한편, 탁상용 선풍기는 직경이 대략 30 cm인 경우가 많으며, 일반적으로 자립식(free standing)이고 휴대가 가능하다. 스탠드용 타워형 선풍기(floor standing tower fan)는 일반적으로 대략 1 m 높이의 긴 수직 연장 케이스를 포함하며, 일반적으로 300 내지 500 l/s(liter/sec) 범위의 공기 흐름을 생성하기 위해 한 세트 이상의 로터리 날개를 수용한다. 공기 흐름이 실내의 넓은 면적에 걸쳐 흘러나가게 되도록 타워형 선풍기로부터의 출구를 회전시키기 위해 왕복회전 기구(oscillating mechanism)를 채용할 수도 있다.Such fans are available in a variety of sizes and shapes. For example, ceiling fans may have a diameter of 1 m or more, and are generally mounted in such a manner as to be suspended from the ceiling to provide a downward air flow to cool the room. On the other hand, a table fan is often about 30 cm in diameter, and is generally free standing and portable. Floor standing tower fans typically include a long vertical extension case approximately 1 m high and typically have one or more sets to produce airflow in the range of 300 to 500 l / s (liter / sec). Accepts rotary wings. An oscillating mechanism may be employed to rotate the outlet from the tower fan such that the air flows out over a large area of the room.
상기와 같은 일반적인 선풍기 또는 타워용 선풍기는 회전날개의 회전수 대비 바람의 토출량이 결정되기 때문에 상대적으로 출력이 높은 모터를 채택하게 되는 단점이 있다.The general fan or tower fan as described above has a disadvantage in that a relatively high output motor is adopted since the discharge amount of the wind is determined relative to the rotation speed of the rotary blade.
즉, 바람의 세기를 결정하는 요인은 선풍기의 회전 날개 사이즈 및 회전수에 의해 결정되나 모터가 사용하는 에너지의 입력 대비 출력이 감소되는 현상을 막을 수 없는 것이 현재의 실정이며 이를 극복하기 위해 바람의 세기를 배가시키는 기술의 제안이 시급한 실정이다.In other words, the factors that determine the strength of the wind are determined by the fan blade size and the number of revolutions of the fan. It is urgent to propose a technology that doubles the century.
상술한 문제점을 해소하기 위한 본 발명의 선풍기는 공기의 압력으로 선풍기에서 기압차이에 의한 기류를 형성시켜 바람의 유속을 증가시켜 외부로 토출하도록 하는 데 있다.The fan of the present invention for solving the above-mentioned problems is to form an air flow by the pressure difference in the fan by the pressure of the air to increase the flow rate of the wind to discharge to the outside.

본 발명에 따르면, 상기 공간은 상호 이격된 2열로 형성되고, 상기 각각의 공간 내부에는 회전날개를 수직 배치하도록 구성한다.According to the present invention, the spaces are formed in two rows spaced apart from each other, and configured to vertically displace the rotor blades in the respective spaces.
본 발명에 따르면, 상기 공간은 2열 2행의 선분 끝단이 상호 연이어 이어지도록 하고, 각각의 공간에 수평 수직 방향으로 회전날개를 설치한다.According to the present invention, the ends of the line segments of two rows and two rows are connected to each other, and the rotary blades are installed in the horizontal and vertical directions in each space.
본 발명에 따르면, 상기 회전날개는 공간에 브라켓을 통해 결합되되, 상기 브라켓은, 길이를 갖는 이음부와, 상기 이음부의 상부에 절곡되게 형성되어 상기 축과 결합하는 이음공을 갖는 고정부와, 상기 이음부의 하부에 절곡되게 형성되어 상기 동력수단의 하부와 결합되는 받침부와, 상기 고정부와 받침부에 연결부를 각기 형성시켜 공간에 형성된 고정브라켓과 일체로 고정되는 연결브라켓으로 구성한다.According to the present invention, the rotary blade is coupled to the space through a bracket, the bracket, a fixing portion having a joint portion having a length, and a joint hole formed to be bent in the upper portion of the joint portion and coupled to the shaft, It is formed to be bent in the lower portion of the joint portion is coupled to the lower portion of the power means, and the connecting portion fixed to the fixed bracket formed in the space by forming a connecting portion to each of the fixed portion and the support portion.
상술한 문제점을 해소하기 위한 본 발명의 선풍기는 틀 형상을 갖는 케이스와 커버를 결합시킨 다음 내부의 공간에 회전수단을 설치하여 유입공으로 외부 공기가 빨아들여 공간의 내부 압력을 높여 배출공으로 빠른 유속의 공기가 빠져나가면서 상기 커버의 바깥 주변 공기가 커버를 통과하면서 기류를 발생시키도록 하여 기압 차이에 의해 바람의 유속을 증가시켜 외부로 토출시킴으로써 보다 강한 바람의 세기를 얻을 수 있는 효과가 있다.The fan of the present invention for solving the above-mentioned problems is to combine the case and the cover having a frame shape and then install a rotating means in the inner space to suck the outside air into the inlet hole to increase the internal pressure of the space to the high speed of the discharge hole As the air escapes, the air surrounding the outside of the cover passes through the cover to generate airflow, thereby increasing the wind velocity by the air pressure difference and discharging to the outside, thereby obtaining a stronger wind strength.

In communication with 111.
그리고, 상기 회전부 130는 상기 공간 111에 회전날개 132를 설치하여 동력수단 133에 의해 회전시키면 유입공 112으로 외부 공기를 공간 111 내부로 빨아들여 배출공 113으로 배출시킨다.In addition, the rotating unit 130 installs the rotary blade 132 in the space 111, when rotated by the power means 133 sucks the outside air into the inlet hole 112 to discharge into the discharge hole 113.
특히, 회전날개 132는 길이를 갖는 축 132a의 외주연에 방사형태로 날개 132b가 복수개로 형성된다.In particular, the rotary blade 132 is formed in a plurality of wings 132b in the radial direction on the outer periphery of the axis 132a having a length.
상기 회전날개 132에는 동력수단 133이 각기 설치되어 직접 동력방법으로 모터의 회전축 132a과 회전날개 132의 축 132a이 이음되어 동력수단 133에서 발생한 회전력을 통해 회전날개 132가 회전될 수 있도록 한다.The rotary blades 132 are provided with a power means 133, respectively, so that the rotary shaft 132a of the motor and the shaft 132a of the rotary blade 132 are directly connected to each other so that the rotary blade 132 can be rotated through the rotational force generated by the power means 133.
또한, 상기 회전날개 132는 공간 111에 브라켓 140을 통해 결합된다.In addition, the rotary blade 132 is coupled to the space 111 through the bracket 140.
상기 브라켓 140은 이음부 141와 고정부 142와, 받침부 144와 연결브라켓 145으로 이루어진다.The bracket 140 includes a joint 141, a fixing part 142, a supporting part 144, and a connecting bracket 145.
즉, 이음부 141는 길이를 갖으며 회전날개 132의 길이와 대등하다. That is, the joint 141 has a length and is equivalent to the length of the rotary blade 132.
또한, 고정부 142는 상기 이음부 141의 상부에 절곡되게 형성되어 상기 축 132a과 결합하는 이음공 143을 갖는다.In addition, the fixing part 142 is formed to be bent in the upper portion of the joint 141 has a joint hole 143 is coupled to the shaft 132a.
그리고, 상기 받침부 144는 상기 이음부 141의 하부에 절곡되게 형성되어 상기 동력수단 133의 하부와 결합된다.In addition, the support 144 is bent to the lower portion of the joint 141 is coupled to the lower portion of the power means 133.
아울러, 연결브라켓 145은 상기 고정부 142와 받침부 144에 연결부를 각기 형성시켜 공간 111에 형성된 고정브라켓 115과 일체로 고정된다.In addition, the connecting bracket 145 is formed integrally with the fixing bracket 115 formed in the space 111 by forming connecting portions in the fixing portion 142 and the supporting portion 144, respectively.
이렇게 브라켓 140 중 연결브라켓 145을 공간 111의 고정브라켓 115에 결합하여 상기 브라켓 140이 공간 111 내부에 설치되도록 한다. 그리고, 상기 브라켓 140의 이음부 141와 고정부 142 사이에 동력수단 133이 탑재된 회전날개 132를 설치한다.The coupling bracket 145 of the bracket 140 is coupled to the fixing bracket 115 of the space 111 so that the bracket 140 is installed in the space 111. In addition, a rotary blade 132 having a power means 133 is installed between the joint 141 and the fixing part 142 of the bracket 140.
결국, 고리 형태의 케이스 110에 형성된 각각의 선분 내부의 공간 111에 회전날개 132를 용이하게 설치하기 위해 브라켓 140을 통해 회전날개 132를 설치할 수 있도록 하여 제조 효율을 향상시키도록 하는 효과가 있다.As a result, in order to easily install the rotary blade 132 in the space 111 inside each line segment formed in the ring-shaped case 110, it is possible to install the rotary blade 132 through the bracket 140 to improve the manufacturing efficiency.
상기와 같이 구성된 선풍기 100는 동력수단 133을 통해 회전날개 132를 회전시키면 유입공 112을 거쳐 외부 공기가 공간 111으로 유입되어 배출공 113을 통해 공기가 배출된다.When the fan 100 configured as described above rotates the rotary blade 132 through the power means 133, the outside air is introduced into the space 111 through the inlet hole 112 and the air is discharged through the outlet hole 113.
그리고, 상기 커버 120는 상기 케이스 110 전방에 맞대어 설치되어 제1개구공 114과 연통되는 제2개구공 121이 마련되어 상기 배출공 113을 통해 제2개구공 121 내부에서 외부로 공기가 배출되도록 한다.The cover 120 is installed to face the front of the case 110 to provide a second opening 121 communicating with the first opening 114 so that air is discharged from the inside of the second opening 121 to the outside through the discharge hole 113.
이때, 상기 제2개구공 121은 내부면이 전방으로 확개된 형태로 경사지게 형성되도록 한다.At this time, the second opening 121 is formed such that the inner surface is inclined forwardly expanded.
결국, 하나 이상의 배출공 113을 통해 배출되는 공기가 제1개구공 114을 거쳐 제2개구공 121측으로 이동하면서 부분적으로 합류되어 공기의 흐름 속도가 빠르게 진행된다.As a result, the air discharged through the one or more discharge holes 113 is partially joined while moving to the second opening 121 side through the first opening 114, so that the air flow rate is fast.
즉, 공기의 속도가 빠른 케이스 110의 제1개구공 114 측은 기압이 낮아지고 상대적으로 제2개구공 121측에 기압이 높아진다. 결국, 공기의 힘은 고기압에서 저기압으로 작용하므로 케이스 110를 통과하는 빠른 속도를 갖는 공기가 외부의 공기를 같이 통과시켜 일정하고 강한 기류를 형성시킴으로써 바람을 발생시키게 된다.That is, the air pressure is lowered at the first opening 114 side of the case 110 having a high air speed, and the air pressure is increased at the 121 opening of the second opening relatively. As a result, the force of air acts from high pressure to low pressure, so that the air having a high speed passing through the case 110 passes the outside air together to form a constant and strong airflow to generate wind.
결과적으로 본 발명의 선풍기 100는 틀 형상을 갖는 케이스 110와 커버 120를 결합시킨 다음 내부의 공간 111에 회전부 130를 설치하여 유입공 112으로 외부 공기가 빨아들여 공간 111의 내부 압력을 높여 배출공 113으로 빠른 유속의 공기가 빠져나가면서 상기 커버 120의 바깥 주변 공기가 커버 120를 통과하면서 기류를 발생시키도록 하여 기압 차이에 의해 바람의 유속을 증가시켜 외부로 토출시킴으로써 보다 강한 바람의 세기를 얻을 수 있는 효과가 있다.As a result, the fan 100 of the present invention combines the case 110 and the cover 120 having a frame shape, and then installs the rotating part 130 in the inner space 111 to suck the outside air into the inlet 112 to increase the internal pressure of the space 111 to discharge the exhaust 113. Air flows out of the cover 120 as the air flows out of the cover 120 so that the outside air passes through the cover 120 to generate air flow, thereby increasing the wind speed by the air pressure difference, and thereby obtaining stronger wind strength. It has an effect.
