A fan is a device that provides coolness by generating wind, and is widely used because of its low price and high efficiency. Such a fan is mainly used around the summer when the temperature is high, but has a characteristic of a seasonal home appliance that has no use in the season when the temperature is dropping and is only stored in a separate place.

On the other hand, recently, air purifiers have been widely used to purify indoor air from fine dust and various harmful gas environments.

Therefore, if the fan commonly used in most homes can be used as an air purifier, it is possible to simultaneously solve both the seasonality of the use of the fan and the cost problem of the conventional air purifier. The effect can be significant.

As a result, the conventional fan having an air purifying function has a large reduction in air volume due to the filter and insufficient performance to remove fine dust and harmful gas, so there is a limit that is not suitable as an air purifier as well as the original function of the fan.

In order to solve this problem, the inventor of the present application has developed a fan unit for a fan that allows a fan commonly used in daily life to be used as an air purifier and a fan assembly having the same (Korea Registered Utility Model No. 20-0489663) Reference).

According to this configuration, the boss 100 is freely rotatably coupled on the rotary shaft 40 , and when the rotary shaft 40 is rotated according to the driving of the motor, the boss 100 coupled to the rotary shaft 40 . ) does not rotate due to the weight of the stator (ie, the weight), but rotates in vain and maintains a stationary state.

Hereinafter, with reference to FIGS. 15 and 16, the dust collecting operation and the ultraviolet sterilization operation of the fan assembly equipped with the fan mechanism of the present invention will be described.

(1) Indoor air purification operation

When the fan equipped with the dust collecting unit is turned on, the rotating shaft 40 coupled to the motor 1 is axially rotated in association with the driving of the motor 1, whereby the first and second disks 10, 60) is induced.

When the rotation of the dust collecting unit starts, the internal air of the dust collecting unit is discharged to the outside by the rotational force of the dust collecting unit, thereby generating a pressure difference between the center and the outside of the dust collecting unit, 15, 65) into the fan unit.

In the dust collecting unit, the centrifugal force rapidly increases from the center of the dust collecting unit to the outside, so that the wind pressure is the highest at the position of the dust collecting filter 20 in the outermost part of the dust collecting unit. Accordingly, the air introduced into the center of the dust collecting unit smoothly passes through the dust collecting filter 20, fine dust, etc. are effectively filtered and then discharged to the outside of the fan unit.

(2) UV filter sterilization action

When the motor 1 and the UV lamps 500 and 510 are turned on, the dust collecting unit connected thereto is rotated to perform the above-described indoor air purification operation, and UV rays are emitted from the UV lamps 500 and 510 .

At this time, when the dust collecting unit rotates, the dust collecting filter 20 formed in a circular band shape continuously enters and leaves the space between the upper housing 200 and the lower housing 300 and repeats the process, and in the entering process Ultraviolet light is irradiated toward the dust collecting filter 20 to sterilize the dust collecting filter 20 .

In particular, even when such ultraviolet sterilization is performed, the dust collecting unit still smoothly introduces and discharges air and can continue to perform the above-described indoor air purification operation. And, as described above, it is possible to prevent exposure of ultraviolet rays emitted in the process of sterilizing the dust collecting filter 20 to the outside, thereby ensuring the safety of the device.

As a result, according to the UV filter sterilization unit according to the present invention, while the air cleaning and dust collecting filter 20 sterilization actions can be performed together, there is an effect that can effectively block the harmfulness to the human body due to UV exposure.
