The inlet 16 has an upper inlet 16a formed through the side of the blower fan 19 at the side of the flow panel 18; And

It is spaced apart from the upper inlet 16a by a predetermined interval, and is formed through the lower portion of the flow panel 18 to a size smaller than the upper inlet 16a, and blows water vapor evaporated from the water tank 13 by the incoming external air A lower inlet 16b for moving toward the fan 19 is further included.

As shown in Figure 2 and 4, the case 20 is mounted on the upper surface, and has a discharge grill 33 for preventing foreign matter from flowing into the blower fan 19 from the outside and the water vapor in the atomized state is discharged.

In the drawings, reference numeral 35 is a shroud for guiding external air to enter and exit the case 20 due to the rotation of the upper fan 22 and the lower fan 23, and 36 is mounted to the opening of the bucket 15. 37 is a drain valve mounted on the bottom surface of the drain panel 36.

Hereinafter, an example of use of the ultrasonic humidifier according to one embodiment of the present specification will be described according to the accompanying drawings.

1 to 5, the inside of the water tank A is divided into the first water tank 13 and the second water tank 14 by the U-shaped cutting groove a formed in the water tank A. As the base 10a formed at the bottom of the partition 10 penetrates the incision groove a and enters the bottom surface of the main body 11, the bucket 15 may be coupled to the seating part 10b formed at the partition 10. Even in this case, the partition 10 may be prevented from falling due to the weight of the bucket 15.

Therefore, the water contained in the bucket 15 coupled to the seating portion 10b is opened by the protrusion formed on the inner bottom surface of the second tank 14 so that the drain valve 35 mounted on the opening of the bucket 15 is opened. Through the second tank 14 is discharged. The humidifying water discharged from the second water tank 14 is moved to and stored in the first water tank 14 communicated with the second water tank 14 through the water movement passage 29.

At this time, the water level of the humidifying water filled in the first and second tanks 13 and 14 forming the water tank A is the same.

When operating the power on / off switch (not shown) formed on the outer side of the main body 11 in the ON state, it is installed in the flow panel 18 by the control signal of the controller PCB (not shown). Power is applied and driven to the drive motor 21 of the case 20.

That is, the blower fan 19 (so-called "upper") is formed of the upper fan 22 and the lower fan 23 that are seated on the flow panel 18 and rotated in opposite directions due to the driving motor 21. Outside air flows through the inlet port 16a formed through the side wall 18a of the flow panel 18 by the suction force of the blower fan 19. Is inhaled.

Therefore, foreign matters of suspended matter such as dust contained in the outside air sucked into the flow panel 18 are filtered by the air purification filter 25 seated on the flange 24 to the flow panel 18. Only clean air filtered by the air purification filter 25 passes through the blower fan 19 and is discharged to the outside of the humidifier.

On the other hand, when the power is applied to the power supply terminal 32 mounted on the upper portion of the main body 11 through a power cable (not shown) formed on the outer bottom surface of the water tank (A) to be conductive with the power supply terminal 32 Power is applied to the contact terminal 31.

Therefore, when mounting the tank A in the main body 11, the contact terminal 31 of the bottom surface of the tank A is conducted to the ultrasonic vibrator 12 of the tank A, and the contact terminal 31 and the power supply are connected. The supply terminal 32 is connected electrically.

Thus, as power is applied to the ultrasonic vibrator 12 formed on the inner bottom surface of the first water tank 13, the humidifying water stored in the first water tank 13 may be ultrasonically vibrated and converted into water vapor.

That is, some of the water vapor in the atomized state generated by the ultrasonic vibrator 12 is flow panel 18 by external air sucked through the inlet 16b formed in the lower portion of the flow panel 18 by the suction force of the blower fan 19. It is moved toward the blowing fan 19 through the curved tube 34 of.

At the same time, some of the water vapor in the atomized state generated by the ultrasonic vibrator 12 is flow panel 18 by external air sucked through the inlet 16b formed in the lower portion of the flow panel 18 by the suction force of the blower fan 19. It passes through the space between the inner surface of the and the curved tube 34 is moved toward the blowing fan (19).

Accordingly, the atomized water vapor generated by the ultrasonic vibrator 12 is blown through the interior of the curved tube 34 of the flow panel 18 and the space between the inner surface of the flow panel 18 and the curved tube 34. After being moved toward the fan 19, it is discharged out of the humidifier (which serves as an ultrasonic humidifier).

As described above, the atomized water vapor generated by the ultrasonic vibrator 12 of the water tank A is sucked into the case 20 by the suction force of the blower fan 19.

That is, the space between the upper fan 22 and the lower fan 23 when the upper fan 22 and the lower fan 23 constituting the blowing fan 19 in the case 20 are rotated in opposite directions. Vortex forms in

When the atomized water vapor generated by the ultrasonic vibrator 12 formed in the first tank 13 passes through the flow panel 18 by the suction force of the blower fan 19 and then passes through the case 20. Vortex formed in the inside of the case 20 is temporarily stagnated inside the case (20).

Accordingly, since the particles generated by the ultrasonic vibrator 12 dry the large vaporized water vapor particles by vortex, the humidified particles can be miniaturized and atomized and then discharged to the outside of the humidifier.

As shown in Figure 7 and 8, the ultrasonic humidifier according to another embodiment of the present specification

A first storage space 11a having an inlet side open at the bottom thereof is formed, and a blower fan 19 is hinged and fixed in multiple stages by a hinge structure 19a at one upper side thereof, and the upper and lower ends thereof are opened at the other upper side thereof. A storage space 11b is formed, and is formed of an inlet 16a having a long hole shape on the outer surface thereof, and an inlet 16b spaced apart from the inlet 16a in a vertical direction and having an inlet 16b of an epicenter. The main body 11 is formed,

An ultrasonic vibrator 12 is provided on the inner bottom surface, and is detachably coupled to the first storage space 11a by sliding movement, and a water tank A in which humidifying water is contained at a predetermined level,

Humidifying water that is detachably coupled to the storage space 11b, the bottom surface of the storage space 11b, and supplied to the water tank A through an opening formed at the bottom of the storage space 11b is accommodated. A bucket 15 is provided.

At this time, since the configuration for supplying power to the drive motor of the ultrasonic vibrator 12 and the blowing fan 19 is substantially the same as the configuration of the humidifier according to an embodiment of the present specification, a detailed description thereof will be omitted. .

According to the humidifier of another embodiment of the present specification configured as described above,

When the water tank A is coupled to the first storage space 11a of the main body 11 by sliding movement, and then the water tank 15 is coupled to the second storage space 11b, the bottom surface of the water tank 15 is Since it is seated spaced apart from a certain height in (A) the humidifying water discharged from the bucket 15 is filled in the tank (A) at an arbitrary height.

By vibrating the ultrasonic vibrator 12 formed on the bottom surface of the water tank A, the water for humidification is converted into water vapor in the atomized state and ejected.

The atomized water vapor generated by the ultrasonic vibrator 12 is moved into a case (not shown) in which the blower fan 19 is built by the suction force of the blower fan 19 mounted above the water tank A.

When the vapor of the atomized state is sucked into the case, the steam discharged in the case is temporarily stagnated by the vortex formed in the space between the upper fan and the lower fan during the rotation of the blower fan 19.

This makes it possible to atomize the humidified particles because the vapor of the atomized state sucked into the case is dried by the vortex.

On the other hand, the water tank A can be easily removed from the main body 11. That is, the tank A coupled to the first storage space 11a may be slid and separated from the main body 11.

Therefore, the water tank A separated from the main body 11 has no structure therein, so that foreign matters such as water moss therein can be easily washed.

As described above, according to the ultrasonic humidifier according to the embodiment of the present specification,

As external air is sucked into the flow panel 18 due to the operation of the blower fan 19, the air purification filter 25 seated on the flow filter 18 filters the suspended substances such as dust contained in the indoor air. The air cleaning function and the ultrasonic vibrator 12 can exhibit the ultrasonic humidifying function of ultrasonically vibrating the water for humidification stored in the water tank A to generate an atomized water submersible and discharging it to the outside.

Herein, while the foregoing specification has been described with reference to the preferred embodiments, those skilled in the art may variously modify and modify the present disclosure without departing from the spirit and scope of the present disclosure as set forth in the claims below.
