Definitions
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

- 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.
- 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.
- 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.
- the fan of the present invention has an effect of providing a rotation means in the case, and by the rotation means to further double the air pressure in the inner space of the case to improve the discharge amount and speed of the air.
- the fan of the present invention has the effect of improving the manufacturing efficiency by allowing the rotary blades to be installed through the bracket in order to easily install the rotary blades in the space inside each line segment formed in the ring-shaped case.

- the fan 100 of the present invention includes a case 110, a cover 120, and a rotating unit 130.
- the case 110 is formed in a polygonal frame shape, and the case 110 has one or more line segments forming a polygon.
- the present invention will be described as a case 110 having a streamline shape having two line segments or a quadrangular shape having four line segments, and the shape thereof is not limited.
- the streamlined case 110 is formed in two rows in which the spaces 111 are spaced apart from each other, and the rotary blades 132 are vertically disposed in the respective spaces 111.
- the rectangular case 110 has the space 111 so that the two ends of two rows of line segments are connected to each other, and the blade 132 is rotated horizontally and vertically in each space 111 divided into up, down, left and right. Install it.
- the case 110 having a polygonal shape is formed to penetrate the first opening 114 in the center in a ring shape as a whole.
- case 110 body having a polygonal shape will be referred to as a frame.
