Abstract

PURPOSE: Electric fan blades and a producing method thereof are provided to generate far infrared ray from the electric fan blades while preventing dust from being attached on the blades. CONSTITUTION: Electric fan blades are formed by stone such as germ stone or elvan for generating far infrared ray. Moreover, dusts are not attached on the electric fan blades by forming the blades by using the stone. Herein, stone powder is mixed with synthetic resin for preventing generation of electrostatic discharge. 30-70wt% of stone powder is mixed with the synthetic resin for producing the electric fan blades. Then, the mixture is injection molded for producing the blades. Herein, the stone powder is formed by 200-500 meshes. Therefore, the electric fan blades formed by stone such as the germ stone or the elvan generate far infrared ray. Moreover, dust in air or fiber particles are not attached on the blades.

Description

선풍기 날개 및 그 제조방법{A Fan Blade and A Method thereof}Fan blades and method for manufacturing the same

본 발명은 선풍기 날개에 관한 것으로서, 특히 옥돌가루를 포함하는 선풍기 날개를 제작하므로써 부착되는 먼지를 현저히 줄일 수 있는 선풍기날개 및 그 제조 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fan blade, and more particularly, to a fan blade and a method of manufacturing the same, which can significantly reduce dust attached by manufacturing a fan blade including jade stone.

선풍기는 바람을 일으키기 위하여 동력 축에 부착되는 날개를 가지고 있다. 이러한 선풍기 날개는 금속으로 만드는 것도 있지만 최근에는 주로 플라스틱으로 성형된 것이 사용되고 있다.The fan has wings attached to the power shaft to generate wind. These fan blades are made of metal, but recently, plastic molded parts have been used.

바람을 일으키는 날개의 형태 중 전기 모터에 결합되는 선풍기 날개로 주로 사용되는 3개의 날과 4개의 날을 가진 날개를 도시하여 보면 도1 및 도2와 같다.1 and 2 show a wing having three blades and four blades which are mainly used as a fan blade coupled to an electric motor.

선풍기의 날개를 회전시키기 위한 동력은 주로 전기 모터가 사용되지만 기타의 동력으로도 날개를 회전시켜서 바람을 일으킬 수가 있다. 선풍기의 용도는 더울 때 시원한 바람을 만들어 주기 위하여 사용되는 가정용 선풍기, 먼지나 가스를 배출하기 위하여 사용되는 환풍기, 가열 공기를 품어 주기 위한 히터용 선풍기, 가열부위의 온도를 식혀 주기 위한 쿨러용 선풍기, 등등 이루 헤아릴 수 없이 그 용도가 많다.The electric motor is mainly used to rotate the blades of the fan, but other electric power can be used to generate the wind by rotating the blades. The use of the fan is a household fan used to create a cool wind when it is hot, a fan used to discharge dust or gas, a fan for heating the air, a fan for cooling the temperature of the heating part, And so many uses.

이러한 선풍기에 사용되는 선풍기 날개에는 사용되는 중에 먼지나 오염분말들이 부착이 되어 오랫동안 사용되면 균형이 맞지 아니하여 진동 소음이 크게 되거나, 회전수가 줄어들어 풍량이 줄어 들거나, 세균의 번식처가 되거나 냄새의 발생 원이 되거나 하는 문제점들이 있었다.The fan blades used in these fans are attached to dust or contaminated powder during use, and if used for a long time, they are unbalanced, resulting in large vibration noise, reduced rotation speed, reduced wind volume, germ breeding, or sources of odor. There have been problems.

본 발명의 목적은 종래의 선풍기 날개가 가지고 있는 이러한 문제점들을 개선하고 더 나아가 선풍기 날개에서 원적외선까지 방사하는 선풍기 날개를 제공하기 위한 것이다.It is an object of the present invention to improve these problems with conventional fan blades and to further provide a fan blade which radiates from the fan blade to far infrared rays.

본 발명에 따른 제조 방법은 바람을 일으키기 위하여 2개 이상의 날을 가진 선풍기 날개를 제조하는 방법으로서 합성수지에 돌 가루를 중량 비로 30 내지 70%를 혼합하여 날개를 성형하는 방법이다. 돌가루는 원적외선을 효율 좋게 방사하는 옥돌 또는 맥반석을 200 내지 500 메쉬로 분쇄한 것을 사용한다.The manufacturing method according to the present invention is a method of manufacturing a fan blade having two or more blades in order to generate the wind is a method of forming a wing by mixing 30 to 70% by weight of stone powder in a synthetic resin. Stone powder is obtained by pulverizing jade or ganban stone from 200 to 500 mesh that emits far infrared rays efficiently.

본 발명의 선풍기 날개는 합성수지에 옥돌 가루를 중량 비로 30 내지 70%를 혼합하여 성형한 것이다.The fan blade of the present invention is formed by mixing 30 to 70% by weight of octane powder in a synthetic resin.

이렇게 제작된 선풍기 날개는 공기 중의 먼지나 섬유 파티클이나 오염물질들이 거의 부착되지 아니하고, 원적외선이 많이 방출되는 효과가 있다.Fan blades thus manufactured are hardly adhered to dust, fiber particles or contaminants in the air, and have a far infrared ray emission effect.

도1 및 도2는 본 발명의 선풍기 날개 사시도이다.1 and 2 are a perspective view of the fan blade of the present invention.

이하에서 본 발명을 구체적으로 설명한다.Hereinafter, the present invention will be described in detail.

합성수지 제품에 연옥 분을 5% 내지 15% 정도 혼합하여 합성수지 제품을 만드는 방법은 특허 공고 번호 97-11094호에 자세히 설명되어 있다.The method of making a synthetic resin product by mixing about 5% to 15% of jade powder in the synthetic resin product is described in detail in Patent Publication No. 97-11094.

원적외선이 잘 나오는 돌에는 옥돌, 맥반석, 등이 있는 것으로 알려져 있다. 또 옥돌에는 경옥과 연옥이 있는데, 연옥에서는 경옥보다 원적외선이 잘 나오는 것으로 알려져 있다.Far-infrared stones are known to have jade, elvan, etc. Jadeite also has jadeite and jadeite, which is known to produce far infrared rays better than jadeite.

합성수지나 금속은 나무, 면, 명주, 운모, 유리, 모피, 등과 마찰하면 (-)전하가 발생되는 것으로 알려져 있다.Synthetic resins and metals are known to generate negative charges when rubbed with wood, cotton, silk, mica, glass, fur, etc.

선풍기 날개에는 많은 먼지들이 부착하게 되는데, 이러한 현상은 합성수지로 성형된 선풍기 날개가 공기 중에서 회전하게 되면 공기 중에 있는 많은 여러 가지 물질의 파크클이나 먼지들과 마찰하면서 정전기가 발생되고 이 정전기에 의하여 대전된 파티클이나 먼지가 날개에 부착되는 것으로 추측되고 있다.The dust is attached to the fan blades. This phenomenon is caused when the fan blades made of synthetic resin rotate in the air and generate static electricity while rubbing against the particles or dust of many different materials in the air. Particles and dust are believed to be attached to the wings.

본 발명의 기본적인 아이디어는 선풍기 날개를 원적외선을 방사하는 물질인 옥돌이나 맥반석과 같은 석재를 사용하여 성형하면 원적외선이 방사되고, 또 먼지가 적게 부착된다는 사실을 발견하고 이 아이디어를 이용하여 선풍기 날개를 제작하려는 것이다. 합성수지에 돌가루가 혼합되면 정전기 발생이 억제 되거나 그 발생량이 현저히 감소될 것이므로 먼지 부착이 억제 될 것이다.The basic idea of the present invention is to find the fact that far-infrared rays are radiated and dust is attached by forming a fan blade using a stone such as jade or ganban stone, which emits far-infrared rays. I will. The mixing of stone powder in the synthetic resin will suppress the generation of static electricity or significantly reduce the amount of dust attached.

도1 내지 도2에서 보인 형태의 선풍기 날개를 열가소성 합성수지를 사출성형하여 제작한다.Fan blades of the type shown in Figures 1 to 2 are produced by injection molding thermoplastic synthetic resin.

본 발명에서는 종래부터 사용되어오고 있는 선풍기 날개 제조용 합성수지에 돌 가루를 중량 비로 30 내지 70%를 혼합하여 날개를 사출 성형한다.In the present invention, the blade is injection molded by mixing 30 to 70% by weight of stone powder in a synthetic resin for producing a fan blade that has been conventionally used.

돌가루가 30% 미만으로 혼합되면 정전기 발생을 억제하는 효과가 적고 또 원적외선도 많이 발생되지 아니하므로 30% 이상은 되어야 하고, 돌 가루를 너무 많이 혼합하면 날개 형태로 성형이 되지 아니할 뿐만 아니라 비록 성형이 된다고 하여도 쉽게 부서질 염려가 있으므로 70%이하가 되도록 혼합비율을 정한다.If the stone powder is mixed at less than 30%, the effect of suppressing the generation of static electricity and the generation of far infrared rays are not generated. Therefore, the amount of stone powder should be 30% or more. Even if it is easy to be broken, the mixing ratio is determined to be less than 70%.

또 돌가루는 분쇄가 잘되어야 하는데, 옥돌이나 맥반석을 분쇄하여 200 내지 500 메쉬 정도 되게 한다. 200메쉬 이하가 되면 표면이 거칠어지고 합성수지와의 결합력도 작아서 견고성이 낮아지고 500메쉬 이상으로 하려면 분쇄하는데 어려움이 많으므로 200 내지 500 메쉬 정도의 분쇄도로 하는 것이 적당하다.In addition, the stone should be crushed well, crushed jade stone or ganban stone to 200 to 500 mesh or so. When it is 200 mesh or less, the surface becomes rough and the bonding strength with the synthetic resin is small, so that the firmness is low, and when it is more than 500 mesh, it is difficult to grind, so it is suitable to have a grinding degree of about 200 to 500 mesh.

이상 설명한 바와 같은 본 발명의 선풍기 날개는 원적외선이 방출되는 효과가 있다. 또 공기 중의 먼지나 섬유 파티클이나 오염물질들이 거의 부착되지 아니하는 효과가 있는 것으로 관찰되고 있다.As described above, the fan blade of the present invention has an effect of emitting far infrared rays. It is also observed that dust, fiber particles or contaminants in the air hardly adhere.
