Description

Rotary fan {A MOTOR FAN}

The present invention relates to a fan apparatus, and more particularly, to maintain a constant angle and a plurality of blow blades having different heights at the same time by operating in a belt power transmission method by a single drive motor blows, as well as rotating 360 ° at the same time It relates to a rotary fan to blow evenly in all directions.

In general, as shown in FIG. 1, the fan is blown by rotating a single blower blade 3 installed on the motor shaft of the driving motor 2 by the driving motor 2, and the driving motor is also blown out. (2) and the blower blade (3) and the protective net (4) surrounding the left and right to reciprocate rotation operation.

However, such a fan was able to blow only a certain area, and in particular, during the rotation, even a person in the above-mentioned compartment had a disadvantage in that the wind could be limited only by the location of the blower blade.

In addition, the fan has a problem such that the heat generated by the drive motor (2) is absorbed by the blower blade (3) is blown as it is, when used for a long time to give a hot wind.

In order to solve such a problem, Korean Utility Model Publication No. 86-2860 discloses a fan for allowing the fan blades to simultaneously blow wind in all directions. In order to assemble a plurality of other bevel gears in the air to install the wind vane on the rotating shaft fixed to each bevel gear, to blow the wind in three directions.

Therefore, there is an advantage that the wind blown in front of the wind vane blows in all directions at the same time, but this also causes the heat from the rotating shaft of the motor to be absorbed by the wind vane to produce hot wind, and also a number of bevel gears. There is a problem in that the noise generated by the increase in the number of revolutions due to the rotational driving method by the engagement structure, or difficult to use the power loss and long time due to the load according to the rotational drive transmission.

On the other hand, a fan for solving the above problems has been filed in the Republic of Korea Patent Application No. 93-12930 by the present applicant.

In detail, the conventional drive motor is installed on the lower protection plate, and the first blower blade is installed at one end of the first rotating shaft rotatably installed at a position spaced apart by a predetermined distance from the upper side of the rotating shaft of the driving motor, while driving the other end. Fixing the transmission roller and the first driving roller;

A second blower blade is installed at one end of the second rotary shaft rotatably installed in the orthogonal direction at a position spaced apart by a predetermined interval to the upper portion of the first rotary shaft, and the second driving roller is fixed at the other end; A third air blower is installed at one end of the third rotating shaft rotatably installed at positions spaced apart by a predetermined interval in a state opposite to the first rotating shaft, and the third driving roller is fixed at the other end; The fourth blower blade is installed at one end of the fourth rotary shaft rotatably installed at a position spaced by a predetermined interval in a state opposite to the second rotary shaft, and the fourth driving roller is fixed at the other end,

The drive shaft of the drive motor and the drive transmission roller on the first rotation shaft is fitted with a drive transmission belt, and each drive roller on the first, second, third, and fourth rotation shafts is fitted with a transmission belt in a U shape to rotate the driving force of the drive motor. The drive transmission belt and the transmission belt are transmitted on the first, second, third and fourth rotational shafts to rotate the respective first, second, third and fourth blower blades simultaneously.

However, the above-mentioned fan apparatus has a disadvantage in that it requires a plurality of belts to be transmitted through a separate drive transmission belt in the drive motor in addition to the transmission belt in order to transmit the rotational driving force to the first, second, third and fourth blow blades.

In order to support and install the first, second, third and fourth rotation shafts, a plurality of fan fixing bars are installed in the outer direction of the lower protection plate, and the bearings are installed at positions different from each other so that the first, second, It is a structure that supports the 3, 4 rotating shafts, which occupies a large amount of overall volume, and has a disadvantage in that space efficiency is reduced due to installation and use.

In addition, since the first, second, third, and fourth blower blades operate only in place, there is a disadvantage that it is difficult to blow evenly in all directions even with four blower blades.

The present invention fundamentally solves the problems of the above-described conventional fan apparatus and the invention filed by the present applicant.

The present invention is intended to maximize the reliability in use, so that the blower blades evenly blow operation while rotating in all directions.

In addition, the present invention has the purpose of simplifying the overall structure, minimizing the volume to efficiently install and use in a small space, thereby maximizing the merchandise.

In addition, the present invention has an object to effectively and constantly apply power to each motor during the rotation operation.

The object of the present invention is to install the first, second and third rotation shafts conforming to the positions of different heights so as to be rotatable in the hexagonal pipe placed in the center of the body, the tip of the first, second and third rotation shafts, The other side is provided with interlocking pulleys of the first, second, and third, respectively, and fitted with a single belt and a driving pulley provided on the driving shaft of the lower driving motor, so as to simultaneously blow and operate the driving motor.

In addition, the hexagonal pipe, the drive motor, etc. by rotating the motor rotates 360 ° by rotating the blower blades on the 1st, 2nd, 3rd rotating shaft to blow evenly, while applying power to the drive motor and the rotating motor, The terminal from below is achieved by a fan unit which constantly applies power while preventing twisting of the power line even by a 360 ° rotation operation.
