Description

fan

The present invention relates to an electric fan configured to maximize use efficiency by blowing air in a lower space indoors in a lateral direction to the upper side to stably circulate and cool the air in the room.

In general, an electric fan is a kind of air conditioner that generates wind with propeller-type blades and feels cool by using vaporization heat.

Such an electric fan is widely used in summer due to its small size and low cost compared to a cooling device using a refrigerant, such as an air conditioner, as well as low power consumption.

Such a fan has a simple structure and is suitable for cooling and heating small spaces such as homes and offices.

Meanwhile, the conventional fan has a problem in that the range of the wind is very narrow because the wind is discharged in one direction.

To this end, a turning device capable of turning at approximately 90° is provided, which also has a problem in that the range of the wind is limited, and the cooling efficiency is deteriorated due to uneven wind strength.

Such a conventional fan typically comprises a set of blades or vanes mounted to rotate about an axis and a drive device for generating an air flow by rotating such a set of blades; A “wind chill” or breeze is generated by the movement and circulation of the air flow, and as a result, heat is dissipated through convection and evaporation, so that the user realizes a cooling effect.

The fan as described above is formed and used in various sizes and shapes depending on the space and environment in which it is used.

For example, some ceiling fans have a diameter of 1 m or more, and are mounted in a manner that is suspended from the ceiling to provide a downward air flow to cool the room.

On the other hand, desktop fans are often about 30 cm in diameter, and are generally free standing and portable.

And the floor standing tower fan comprises a long vertical extension case approximately 1m high; Generally made by accommodating one or more sets of rotary blades to create an air flow in the range of 300 to 500 l/s (liter/sec); An oscillating mechanism may be applied to rotate the outlet from the tower fan so that the air flow flows out over a large area of the room.

However, such a conventional fan has a problem in that wind is discharged only within a rotational angle, and wind is discharged only within a limited angle, and the role and function of the fan are limited as the wind is discharged only in one direction. There was a problem to become.

Accordingly, in recent years, vertical fans are being proposed in which the wind discharged by the blades is discharged in all directions by 360°.

In Korea Utility Model Application No. 20-2018-0000368 (name: vertical fan/2018.01.24.), as known in the publication, a main body in which a driving motor is built so that the blades rotate; A rotation shaft installed on the upper side of the main body so as to be rotatable by the drive motor; A plurality of blades installed on the rotation shaft to generate wind by rotation of the rotation shaft; A case formed so that the wind generated by the rotation of the blades is discharged in all directions by 360°, wherein the blade is provided with an electric fan installed to be replaceable on the rotation shaft.

However, in the conventional fan as described above, since the intake direction and the discharge direction of air are formed on the same horizontal line, there is a problem in that smooth intake and exhaust of air is not performed, and thus the circulation efficiency of air decreases and the quality of use is deteriorated.

The present invention has been proposed to solve the conventional problems as described above, and an object of the present invention is to cool while stably circulating the air in the room by blowing air in the lower space from the room to the upper side, Particularly, it is to provide a fan designed to maximize the use efficiency by improving the cooling efficiency of the room by pulling up the cold air located at the lower part of the room because it is heavy and cold and then blowing it all over the room.

The fan according to the present invention for achieving the object of the present invention as described above, and a post disposed while having a length vertically with respect to the floor; A blower body provided on the upper part of the post and having an intake port through which air is introduced, an exhaust port through which air is discharged to the outside, and a blowing chamber defining a moving space for air between the intake port and the exhaust port; A blower motor configured to generate a rotational force configured to rotate a blower fan disposed rotatably in the blower chamber by receiving power through control of a control means for controlling power of the power supply unit; The blower main body includes: a housing provided at an upper portion of the post, having the air intake port at a lower portion, and having the air blower chamber therein, and having an upper opening; And an upper cover provided with a gap in the upper portion of the housing to form the exhaust port outwardly from the upper portion of the housing to blow air in a horizontal direction.

The fan according to the present invention made as described above blows the cold and heavy air remaining in the lower space from the indoor to the horizontal direction through the air blower body arranged with the height from the floor to the upper by the pillars in a horizontal direction from the upper to the interior. It has the effect of cooling while efficiently circulating the air.

At this time, it has the effect of maximizing the use efficiency by improving the cooling efficiency of the room by drawing up the cold air located at the lower part of the room because it is heavy and cold, and then blowing it all over the room.
