The submodule humidifier according to the present invention may be configured to include a water tank 100, a buoy 200, a vibrator 300, and a wireless power supply member 400 as shown in FIG.

The water tank 100 is a member in which water is accommodated. As shown in FIG. 1, the water tank 100 may be formed in a cylindrical shape, and the upper portion may be opened, and the cover 110 through which the mist is discharged may be detachably coupled.

The water tank 100 may be supplied with water through separation of the cover 110, or alternatively may be provided with a water connection member (not shown) to continuously supply water.

Here, the water tank 100 may be formed of a material such as ABS, PET, Teflon, etc., together with the buoys 200 described later, or may be formed of a non-ferrous metal other than iron.

The buoy table 200 is composed of a buoyant body having buoyancy to provide an installation site of the vibrator 300. The buoyant 200 is introduced into the water tank and floats along with the vibrator 300 in the water surface.

The buoy 200 may be constructed of a material such as foamed styrofoam to provide buoyancy, and a hollow portion 213 may be formed as shown in FIG. 1 to provide buoyancy through the sealing of the hollow portion 213 have.

For example, the buoy 200 may comprise a buoy body 210 and a buoy cover 220, as shown in Figs.

1 and 2, the buoy body 210 is formed in a donut shape with a through-hole 211 at the center, and the vibrator 300 is installed in the through-hole 211. The through- A hollow portion 213 is formed at the side of the hollow portion 213 to provide buoyancy through the hermetic sealing of the hollow portion 213 and floats on the water surface together with the vibrator 300.

The buoy cover 220 is detachably coupled to the lower portion of the buoy body 210 as shown in FIGS. 1 and 2 to seal the hollow 213.

It is preferable that the buoy cover 220 is provided with an unillustrated packing along a surface in close contact with the buoy body 210.

Here, in order to generate mist in the vibrator 300, the vibrator 300 must be flooded.

To this end, the buoy body 210 is formed with a communication hole 212 for communicating the upper portion of the inner circumferential surface of the through-hole 211 and the lower portion of the through-hole 211, as shown in Figs.

That is, the vibrator 300 is installed in the through passage 211 of the buoy body 210, and the water in the water tank flows from the bottom surface of the buoy body 210 through the communication hole 212 to the upper portion of the through hole 211 So that the mist can be smoothly generated.

Such an oscillator 300 may be a conventional structure for generating mist by generating ultrasonic waves through vibration by power supply as in a structure provided in a normal humidifier.

The wireless power supply member 400 is a component that supplies external power to the vibrator 300 to operate it, and supplies power to the vibrator 300 in a non-contact manner.

1, the wireless power supply member 400 includes a power transmission coil 410 and a power reception coil 420. The power transmission coil 410 and the power reception coil 420 are connected to each other through a conductive induction- .

As shown in FIG. 1, the power transmission coil 410 generates a magnetic field by an external power source in the state where it is installed on the outer circumferential surface of the water tub 100, and forms an induction current on the inner circumferential surface of the water tub 100.

The power transmitting coil 410 is connected to an external power source through an unillustrated electric wire.

1, the power receiving coil 420 is connected to the vibrator 300 by wires (not shown) in a state where the power receiving coil 420 is installed on the hollow portion 213 of the buoy body 210 constituting the buoy 200, And receives the induced current as it faces the transmission coil 410 to operate the vibrator 300.

That is, the vibrator 300 generates a mist while operating by an induction current supplied in a non-contact manner through the power transmission coil 410 and the power reception coil 420.

1, the power transmission coil 410 is installed on the outer circumferential surface of the water tub 100 from the upper side to the lower side and is not installed on the lower end of the water tub 100. [ This is to prevent the vibrator 300 from operating at the lower end of the water tub 100.

That is, the vibrator 300 is operated by being supplied with electric power only in a portion where the power transmission coil 410 and the power reception coil 420 face each other, and in the portion where the power transmission coil 410 is not installed, Operation stops.

The power transmission coil 410 is not installed at the lower end of the water tub 100 and thereby prevents the vibrator 300 from operating when the buoy 200 is positioned at the lower end of the water tub 100 due to the lowering of the water level.

Here, since the power transmission coil 410 is installed in the water tub 100 as a whole and generates an induction current, unnecessary power consumption occurs in a portion that does not face the power receiving coil 420.

The wireless power supply member 400 of the present invention may further include a coil slider 430 and a coil elevator 440 as shown in FIG. 3 to prevent power consumption as described above.

The coil slider 430 is formed to have a size corresponding to the buoy 200 as shown in FIG. 3 and is elevably coupled along the outer circumferential surface of the water tub 100. The coil slider 430 includes a power transmission coil 410, (Not shown).

The coil slider 430 is formed in a tubular shape fitted to the outer circumferential surface of the water tub 100 and moves up and down the electric power transmission coil 410 while lifting along the longitudinal direction of the water tub 100.

The coil elevator 440 is a component that connects the coil slider 430 to the water tray 100 so that the coil slider 430 can be lifted and lowered and the coil slider 430 is raised and lowered to the same height as the buoy 200.

That is, the coil elevator 440 elevates and lowers the coil slider 430 at the same height as the buoy 200 ascending and descending by the water level, thereby always facing the electric power transmitting coil 410 to the electric power receiving coil 420.

The coil elevator 440 may include a rack gear 441, a pinion gear 442, a pinion motor 443, and a water level sensor 444 as shown in FIG.

The rack gear 441 is formed along the longitudinal direction on the outer peripheral surface of the water tub 100. The rack key 441 may be formed only in a part of the water tub 100, or may be formed in a plurality of rows.

The pinion gear 442 engages with the rack gear 441 while being mounted on the coil slider 430 as shown in Fig. 3 and lifts the coil slider 430 while rotating by the operation of the pinion motor 443.

The pinion motor 443 is driven by a controller (not shown) to rotate the pinion gear 442 forward or reverse.

The water level sensor 444 is a component for operating the pinion motor 443 according to the water level of the water tank 100. The water level sensor 444 detects the water level of the water tank 100 in a state where it is installed in the buoy 200, To the controller (not shown).

The coil slider 430 ascends and descends to the height corresponding to the buoy 200 as the pinion gear 442 rotates while the pinion motor 443 is operated by the sensing signal of the water level sensor 444, The transmission coil 410 is always facing the power receiving coil 420 so that the power supply can be smoothly performed.

Here, the coil elevator 440 may have a different configuration in place of the configuration of the water level sensor 444. [

That is, the coil elevator 440 satisfies any configuration as far as the coil slider 430 can be positioned at a height corresponding to the buoy 200.

For example, instead of the configuration of the water level sensor 444, the coil elevator 440 may be configured as an ultrasonic sensor or a photosensor capable of detecting the position of the buoy 200.

3, the present invention may further include a UV lamp 500.

3, the UV lamp 500 is installed on the bottom surface of the buoy 200 and connected to the power receiving coil 420, and sterilizes fungi and germs in the water tank while emitting ultraviolet rays.

Ultraviolet rays have germicidal power as it is known. Particularly, those having a wavelength of around 250 nm have a large sterilizing power, and 99% of Escherichia coli, Diphtheria, and Heterogeneous bacteria are sterilized by irradiating ultraviolet ray having a intensity of 100 μW per 1 cm 2 for 1 minute.

Accordingly, the humidifier of the present invention is more hygienic since the occurrence of mold fungi in the water tank and the habitat and the habit of other bacteria are prevented.

As described above, according to the submodule humidifier of the present invention, since the power source is wirelessly supplied to the vibrator 300 installed on the buoy 200 using the electromagnetic induction method, the vibrator 300 smoothly ascends and descends smoothly So that the buoy 200 can be easily separated from the water tray 100 and the shape of the water tray 100 can be easily configured so that the vibrator 300 and the water tray 100 can be easily cleaned.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various changes, substitutions, and alterations can be made therein without departing from the spirit of the invention.
