In addition, the air purifier 40 may use a HEPA filter that removes dust and dust instead of an anion generator or an anion generator for removing odors, dust, and other moisture.

Here, the HEPA filter is made of a cut type using glass fiber as a raw material, and is also called a high performance filter. Since the function of the HEPA filter is different from that of the anion generator, it may be used together with the anion generator.

In addition, the air purifier 40 may be further installed by using a carbon net (carbon net), the carbon net is a carbon component as the main component to use the activated carbon fibers having a large surface area of granular activated carbon or pore structure desirable.

In addition, the air purifier 40 may be replaced with a new one or regenerated when the air purifying function is degraded due to long-term use.

On the other hand, the blowing direction controller 50 is the grill case 51 detachably coupled to the air outlet 22, and the blowing direction of the air discharged coupled to the grill case 51 is adjusted vertically and horizontally Vertical and horizontal grills 52 and 53, and knobs 54 which are installed on the grill to adjust the blowing direction by adjusting the angle of any one or both of the vertical and horizontal grills 52 and 53. It is composed.

In addition, the controller 60 is embedded in a predetermined position of the housing 20 to control the operating state of the blower 30 (Printed Circuit Board: PCB, 61), and the printed circuit board 61 It is coupled to the) is provided with a control means 62, such as a switch for adjusting the application of external power.

Here, the printed circuit board 61 has a function of controlling the intensity of the blowing according to the rotational speed of the blower 30 and a timer function of controlling the operating time of the blower 30, the operation means 62 Is a power switch 62a for adjusting the on / off of the power supplied to the blower 30 and the strength of the blower 30, and a timer switch 62b for setting and controlling the operation time of the blower 30. Consists of.

In addition, the controller 60 further includes a display means 63 such as an LED for visually informing the outside of the operation state of the blower 30.

Referring to the operation of the fan with an air purification function of the present invention made as described above are as follows.

First, when the external power is applied to the printed circuit board 61 by turning on the power switch 62a, the printed circuit board 61 outputs power to the blower 30 to operate the blower 30. As the blower fan 32 coupled to the tip of the motor 31 of the blower 30 rotates, external air is sucked from the air inlet 21.

As the outside air sucked in this way passes through the air purifier 40, contaminants such as dust, moisture, and odors are removed, and the remaining fresh clean air passing through the air purifier 40 passes through the blower 30 at high speed. It is discharged toward the air outlet 22.

Thereafter, the air flowing toward the air outlet 22 passes through the blowing direction controller 50 to be discharged to the outside again, and the user adjusts the wind direction to a desired position by rotating the knob 54 of the blowing direction controller 50. You get fresh air.

That is, the vertical grille 52 and the horizontal grille 53 may be coupled to each other to form a grid having various shapes and directions. Fresh air discharged from the blower 30 may be formed by the grills 52 and 53. It is discharged to the outside air along the formed grid space. Therefore, the user can operate the knob 54 to rotate the grills 52 and 53 to adjust the blowing direction by adjusting the inclination direction of the lattice.

On the other hand, the fan of the present invention can be variously adjusted the blowing amount, and also has a timer and operation display function bar, as described with reference to Figure 4 as follows.

First, the blowing amount of the blower 30 is weakly blown at the same time as the power is turned on by pressing the power switch 62a once, and presses the power switch 62a once more to increase the rotation speed of the blower 30 to blow strongly. When the power switch 62a is pressed once more, the power is controlled to be turned off.

In other words, each time the power switch 62a is pressed, the signal is repeated as weak → strong → off → weak.

In addition, as the power switch 62a is turned on / off, the LED, which is the display means 63, also blinks to indicate whether the fan is operated. The blinking method can be operated in conjunction with the operation process of the power switch 62a.

For example, as described above, LED1 63a is turned on when the power switch 62a is pressed once to weaken the airflow, and when the power switch 62a is pressed twice to make the air blowing stronger, the LED1 63a is turned off and LED2 is turned off. 63b is turned on, and all the LEDs 63a and 63b can be turned off when the power is turned off by pressing the power switch 62a again. Therefore, the user can visually recognize the blowing state depending on whether the LEDs 63a and 63b blink.

Then, the timer function of the controller 60 is turned off automatically after the fan is driven until the set time when the timer switch 62b is turned on with the power switch 62a turned on regardless of the mode of the power switch 62a. Will be.

Herein, the setting time may be variously set. For example, when the timer switch 62b is pressed once, it is turned off after 5 minutes by the timer circuit of the embedded printed circuit board 61, and when the timer switch 62b is pressed once more, the power is turned off after 10 minutes. You can assign the timer function.

That is, each time the timer switch 62b is pressed once, the timer function can be set so as to repeat 5 minutes → 10 minutes → timer off.

As in the airflow control method, the timer setting time can be visually informed through the LED3, 4 (63c, 63d) according to the timer setting region.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea of the present invention.

According to the fan with the air purifying function of the present invention as described above, it is possible to purify pollutants such as odor or smoke in the air by using the air purifier, so that the heat that is not solved by the fan alone in the kitchen or toilet or other special purpose room And by removing the odor and the like can provide a comfortable environment.

In addition, it is possible to prevent the fire blowing in the wind during cooking by intensively blowing only the portion desired by the user through the blowing direction controller.

Accordingly, the user can cook while shooting fresh and fresh air without being affected by the fire blown by the fan.
