Air that passes through the liquid miniaturization device is provided with a suction port, an inner cylinder air passage that communicates with the suction port, a liquid miniaturization means provided in the inner cylinder air passage, and an inner cylinder air passage and an inner cylinder. It passes in the order of the ventilation port that communicates with the outer cylinder air passage provided on the outer circumference of the air passage, the outer cylinder air passage, and the air outlet that communicates with the outer cylinder air passage. The means of liquidation and the ventilation port are arranged in this order. The air passing through the outer cylinder air passage is blown upward in the vertical direction, and the liquid miniaturization means is a hollow inner cylinder forming the inner cylinder air passage.

Further, the outer cylinder air passage of the liquid miniaturization apparatus according to item 3 of the present invention is formed from the ventilation port to the upper side in the vertical direction of the inner cylinder air passage, and is outside in the upper direction in the vertical direction of the outer cylinder air passage. It is also possible that an air passage expansion portion having a larger air passage than the tubular air passage is provided, and an air outlet is formed above the air passage expansion portion in the vertical direction.

With this configuration, the wind speed can be reduced when the air containing water droplets generated by the liquid miniaturization means passes from the inner cylinder air passage to the outer cylinder air passage, and the separation of water droplets due to gravity can be promoted. In addition, since the outer cylinder air passage rapidly expands to the air passage of the air passage expansion part where the air passage is large, a vortex of the air flow is generated, and the vaporization efficiency of the water droplet can be improved by promoting the mixing of the water droplet and the air. ..

Further, the water guide rib 21 is provided so that the lower end thereof is below the water surface stored in the liquid storage unit 11.

The operation will be described below.

First, water is supplied from the water supply port 12 to the liquid storage unit 11 from a water supply facility (not shown), and water is stored in the liquid storage unit 11. The air sucked into the liquid miniaturization device 1 from the suction port 2 by a blower (not shown) is the inner cylinder air passage 4, the liquid miniaturization means 17, the ventilation port 8, the outer cylinder air passage 9, and the air passage expansion portion. It passes in the order of 15, and is blown out from the air outlet toward the outside, for example, the living room. At this time, the water droplets generated by the liquid miniaturization means 17 come into contact with the air, and the water droplets vaporize to humidify the air. Further, the water stored in the liquid storage unit 11 is discharged from the drain port 13 after a predetermined time has elapsed.

The detailed operation will be described. The air taken into the inner cylinder 5 of the inner cylinder air passage 4 from the suction port 2 through the suction communication air passage 7 passes through the liquid miniaturization means 17 provided at a position covered by the inner cylinder 5. When the liquid miniaturizing means 17 is rotated by the operation of the motor 20, the water stored in the liquid storage unit 11 by the rotation rises along the inner wall surface of the suction pipe 18. The raised water is stretched along the surface of the rotating plate 19, and is discharged as fine water droplets from the outer peripheral edge of the rotating plate 19 toward the rotating surface. The released water droplets collide with the inner wall surface of the inner cylinder 5 and are crushed to become finer water droplets. The water droplets discharged from the rotating plate 19 and the water droplets crushed by colliding with the inner wall surface of the inner cylinder 5 come into contact with the air passing through the inner cylinder 5, and the water droplets are vaporized to humidify the air. Further, although a part of the generated water droplets is not vaporized, since the liquid micronizing means 17 is arranged so as to be covered with the inner cylinder 5, the unvaporized water droplets adhere to the inner surface of the inner cylinder 5 and fall. do.

Then, the air containing the water droplets is blown out from the ventilation port 8 provided at the lower end of the inner cylinder 5 toward the liquid storage portion 11 provided below. Then, the air blown out from the ventilation port 8 flows toward the outer cylinder air passage 9 formed between the inner cylinder 5 and the outer cylinder 10, and the air passing through the outer cylinder air passage 9 is vertically upward. Since the air is blown toward the air, the air flowing downward in the inner cylinder air passage 4 and the air blowing direction change to face each other.

At that time, the water droplets blown out from the ventilation port 8 together with the air cannot follow the air flow due to its inertia, and adhere to the water surface of the liquid storage unit 11 or the inner wall surface of the outer cylinder 10. The heavier the weight of the water droplet, the greater the effect, that is, the larger the diameter of the water droplet, which is less likely to vaporize, the greater the effect. Therefore, it is possible to separate the large water droplet from the flowing air.

Then, the air that has flowed from the inner cylinder air passage 4 into the outer cylinder air passage 9 through the ventilation port 8 flows upward through the outer cylinder air passage 9. Then, it flows into the air passage expanding portion 15.

As shown by the dotted arrow 24 in FIG. 2, the air flowing into the air passage expansion portion 15 collides with the sudden expansion of the air passage and the top plate 16 of the air passage expansion portion of the air passage expansion portion 15, and the wind speed suddenly increases. descend. Further, some air flows in a swirling manner inside the air passage expanding portion 15.

At this time, a part of the water droplets falls due to gravity due to a sudden drop in the wind speed or a vortex of the airflow, a part adheres to the upper surface side of the inner cylinder top plate 6, and a part is a wall surface of the air passage expansion portion 15. Or it adheres to the bottom surface. Then, the water droplets adhering to the inner cylinder top plate 6 flow along the inclination of the inner cylinder top plate 6 and fall along the outer wall surface of the inner cylinder 5 to the liquid storage unit 11. Further, the water droplets adhering to the wall surface of the air passage expanding portion 15 flow to the bottom surface of the air passage expanding portion 15 due to gravity, and then flow along the inclination of the bottom surface of the air passage expanding portion 15 along the inner wall surface of the outer cylinder 10. It flows downward and falls into the liquid storage unit 11.

Then, the mixing of water droplets and air is promoted by the decrease in wind speed and the vortex of the air flow in the air passage expanding portion 15, and the vaporization of water droplets proceeds. Then, the air vaporized by the water droplets passes through the air outlet 3 provided on the top plate 16 of the air passage expansion portion 15 of the air passage expansion portion 15 and is blown out toward the outside of the device, for example, the living room.

Further, since the liquid miniaturizing means 17 is arranged at a position covered by the inner cylinder 5, the water droplets adhering to the inner surface of the inner cylinder 5 are prevented from being re-scattered by the wind pressure from the ventilation port 8 of the inner cylinder. Can be suppressed.

Further, since the rotating plate 19 of the liquid miniaturizing means 17 is arranged near the lower end of the inner cylinder 5, the amount of water released from the rotating plate 19 and adhering to the inner cylinder 5 without being vaporized is minimized. can do. For example, even if the air volume is large and the wind speed passing through the ventilation port 8 becomes high, the amount of water droplets that fall along the inner wall of the inner cylinder 5 and are scattered again as large water droplets from the ventilation port 8 due to the wind pressure of the passing air. It can be reduced.

Further, since the water guide rib 21 is provided, the water falling along the inner wall of the inner cylinder 5 can be carried down the surface of the water guide rib 21 and dropped on the water surface 23, so that the re-scattering of water droplets due to wind pressure is suppressed. can do. Further, since the water guide rib 21 is provided so as to gather in the center of the liquid miniaturization device as it goes downward, water can be guided to a place farther than the outer cylinder air passage and where the wind speed is low. It is possible to suppress the scattering of water droplets from the water guiding rib 21.

An eliminator 22 that separates water droplets from the air passing through the internal space of the air passage expanding portion 15 may be provided. As a result, even when the air volume or the amount of water droplets generated by the liquid miniaturization means 17 temporarily increases, the discharge of water droplets from the outlet 3 can be suppressed by the action of the eliminator 22.

As described above, the liquid miniaturization apparatus of the present invention can promote the vaporization of water droplets generated by the liquid miniaturization means 17 and can improve the water droplet separation performance.

Further, a ventilation device, an air purifier and an air conditioner using the liquid miniaturization device of the present invention can be configured. Although not shown, the ventilation device, the air purifier, and the air having a humidifying function are built in the ventilation device, the air purifier, and the air conditioner, and the liquid micronization device of the present invention is provided in a part of the air passage. A harmonizer can be realized.
