Description

TECHNICAL FIELD The present invention relates to a mist generator that emits nano-mist and negative ions into a room to humidify and clean the air in the room.

As a conventional example, inside a large casing, a rotating shaft from a motor is equipped with multiple discs with water uptake holes and edges. The rotation of these discs scoops up water and turns it into mist in an outer mesh cage. There was a mist generator that releases moderate humidity and negative ions in the room to supplement bacteria. (For example, see Patent Document 1.)

Such a mist generator is too large to be incorporated into a domestic air conditioner or heater, and thus needs to be made compact.

In order to solve the above problems, in the present invention, the casing surface has an air suction port and an air outlet,
a water receiver that maintains a predetermined water level within the casing;
A disc that rotates when part of the outer circumference comes into contact with the water surface and splashes water to generate mist,
a blower fan that is coaxial with the rotating shaft of the disk and blows air sucked from the suction port and blows mist generated by the disk from the air outlet;
Having a motor that rotates the disk and the blower fan,
A large number of blades a erected at the outer peripheral tip of the disc are alternately provided in the thickness direction of the disc ,
Alternatingly provided with a large number of blades b standing on the outer peripheral tip and protruding outward in the thickness direction of the disc,
The blades a and b are alternately arranged in the thickness direction of the disk .

In the present invention, by alternately providing a large number of blades a at the outer peripheral tip of the disk in the thickness direction of the disk, mist can be generated efficiently, so that the mist generator can be made compact. can be done.
Further, by alternately providing a large number of blades b protruding outward in the thickness direction of the disk, mist can be generated more efficiently.
Further, by slanting the blades b in a direction opposite to the direction of rotation of the disk, it is possible to reduce the noise generated when the blades b collide with the water surface.

A mist generator according to one embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

Reference numeral 1 denotes a mist generator of this embodiment, which is used by being incorporated in a domestic air conditioner or heater. A casing 2 forms an outer frame of the mist generator 1, and has an air suction port 3 and a blowout port 4 for blowing out mist-containing air on the upper surface.

The casing 2 has a base 30 integrally forming a bottom surface, a rear surface, and left and right side surfaces, a front panel 31 forming a front surface, and an upper panel 32 forming an upper surface.

A partition plate 5 partitions the interior of the casing 2 into the front and rear, thereby forming an air introduction chamber 6 in the front and a splashing chamber 7 in the rear to maintain a predetermined water level in the lower water receiving portion w. Further, the partition plate 5 has a suction hole 8 opened in a circular shape at substantially the center thereof. Reference numeral 9 denotes a centrifugal fan type blower fan which is positioned in the water splashing chamber 7 behind the suction hole 8 and blows the air sucked through the suction hole 8 to the blowout port 4 side.

A disc 10 is provided at the rear of the blower fan 9. A large number of blades a provided at the tip of the outer circumference of the disc rotate in contact with the surface of the water, and the water is splashed up to generate mist. This vane a is formed perpendicular to the direction of rotation of the disk 10 . In addition, the disk 10 has a small area of each blade a and has a large number of blades a alternately arranged in the thickness direction, so that the noise generated by the collision of the blades a with the water surface can be reduced. A disc 10 is a motor provided on the rear surface of the casing 2, and a rotary shaft 12 is provided through a base 30. Rotation of the motor 11 causes the fan 9 and the disc 10 to rotate. The disk 10 has a diameter of about 60 mm and a thickness of 8 mm. .

A right guide 33 formed integrally with the base 30 is provided on the right side of the blower fan 9, and a left guide 34 formed integrally with the base 30 is provided on the left side of the blower fan 9. , and is formed with an appropriate space between it and the blower fan 9 . Blower fan 9 and disk 10 rotate in the direction of the dashed arrow in FIG. (Counterclockwise rotation) As a result, air is efficiently blown, and the water droplets splashed by the blades a collide with the wall surfaces of the casing 2, the partition plate 5, etc., and mist is generated. blow out from In this way, by alternately providing a large number of blades a in the thickness direction of the disk 10 at the outer peripheral tip of the disk 10, mist can be efficiently generated, so the mist generator 1 can be made compact. can do.

A water supply port 35 is provided on the side surface of the water receiving portion w of the water splashing chamber 7, to which a water supply pipe 36 is connected. A water supply means (not shown) such as a cartridge tank is provided at the end of the water supply pipe 36 to maintain the water level of the water receiving portion w.

A disk 10 of another embodiment will be described with reference to FIGS. 6-7. The blades a provided at the tip of the disk 10 protrude outward in the thickness direction (front-rear direction), and a large number of blades b are arranged so that the center side in the thickness direction of the disk 10 is the front side in the rotation direction and the thickness direction of the disk 10. By alternately providing the outside so that the rear side in the rotation direction, the amount of mist generated can be increased, and the mist can be generated more efficiently. Further, the blades b are arranged in the opposite direction to the rotation direction of the disk 10 so that the center side in the thickness direction of the disk 10 is the front side in the rotation direction and the outer side in the thickness direction of the disk 10 is the rear side in the rotation direction. , the noise generated by the blades b colliding with the water surface can be reduced.

Next, the operation of this embodiment will be described.
When the motor 12 rotates, the fan 9 and the disk 10 rotate. As a result, the air sucked from the suction port 3 passes through the blowing fan 9 through the suction hole 8 of the partition plate 5 and is blown out from the blowout port 4. - 特許庁At the same time, the vanes a and b at the tip of the disk 10 splash water, and the splashed water droplets collide with the walls of the casing 2 and the partition plate 5 to generate mist, which is blown together with air to the outlet 4. It blows out from

As described above, according to the present invention, by alternately providing a large number of blades a in the thickness direction of the disk 10 at the outer peripheral tip of the disk 10, it is possible to efficiently generate mist. The generator 1 can be made compact.
In addition, by alternately providing a large number of blades b protruding outward in the thickness direction of the disk 10, mist can be generated more efficiently.
Further, by slanting the blades b in the direction opposite to the direction of rotation of the disk 10, the noise generated when the blades b collide with the water surface can be reduced.

Further, in the present embodiment, the blower fan 9 and the disk 10 have been described as an integral structure, but the blower fan 9 and the disk 10 may be provided separately. A different kind of fan, such as a fan, may be used.

In addition, other configurations used in the present embodiment are presented as an example, and are not intended to limit the scope of the invention, and can be implemented in various other forms. Various omissions, replacements, and changes can be made without departing from the scope of the description. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and equivalents thereof.
