DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1 is an exploded perspective view of a preferred embodiment of the humidifier of the present invention, and FIG. 2 is a partially cutaway perspective view showing an assembled state of the embodiment.
In the drawings, for convenience, reference numerals indicating spaces and openings are underlined or drawn with arrows. The humidifier of the present embodiment includes a lower disk 10. A water container 14 including a closed partition 12 is formed in a central portion on the lower disk 10. In this embodiment, the upper surface of the lower disk 10 forms the bottom of the water container. However, a water container having a bottom can be placed on the lower disk 10. Water container 14
The height of a part of the partition wall 12 is lower than the other parts, and the lowered part becomes the water outlet 16 of the water container 14 . That is, the water outlet 16 is an opening provided above the partition wall 12. A spiral rib 18 is provided on the lower disk 10, and a proximal end of a spiral passage 20 formed by the rib 18 communicates with the water outlet 16. The end of the spiral passage 20 opens on the peripheral edge of the lower disk 10. The spiral rib 18 has a plurality of concave portions 22 that are concave in the radial direction of the spiral. In addition,
In the illustrated example, the partition wall 12 of the water container 14 and the spiral rib 18 are formed by an integrally formed member.
The partition wall 12 and the rib 18 may be formed of different members.
Also, in the illustrated example, a spiral passage is shown for simplicity.
20 is wound only one time, but in an actual apparatus, it is not particularly limited, but it is preferable to wind it around two to ten times in order to enhance the humidification efficiency. On the rib 18, an upper disk 24 having an opening at the center is fixed in a watertight manner. In the center of the lower disk 10, there is a rotating shaft 2 of the motor 28.
The upper portion of the motor 28 is fixed to a central portion of an upper casing 30 described later via an opening of the upper disk 24. When the motor 28 is immersed in water, it is preferable to use a waterproof motor. Or,
The motor 28 can be housed in a waterproof casing (not shown) so that the motor 28 is not immersed in water, and the length of the rotating shaft 26 is increased so that the motor 28 is positioned above the water surface. Can also be designed. The headrace 32 is connected to the bottom of the water container 14.
Both ends of 2 are open to the bottom of the water container 14 and the inside of a lower casing 34 described later. The opening of the water conduit 32 in the lower casing 34 opens in the rotation direction of the lower disk 10, that is, by rotating the water conduit 32 in the water stored in the lower casing 34. , Water enters the water conduit 32.

The lower disk 10, the water container 14 , the ribs 18, the upper disk 24, and the water conduit 32 are fixed to each other, so that they constitute a rotating body that rotates together during operation. The rotating body is housed in a casing, and in the illustrated example, the casing includes a cylindrical lower casing 34 and an upper casing 30. The lower casing 34 is made of a bottomed cylinder as shown, and the upper casing 30 is made of a cylinder having the same radius as the lower casing 34 and having a top plate. As shown in FIG. The parts are fitted to form a casing. At the top of the upper casing 30, a suction port consisting of an opening is provided.
A bar 37 is formed in the diameter direction of one of the suction ports 36 , and the motor 28 is fixed thereto. Therefore, the motor 28 and the rotating body are
It is in a state of being suspended from the upper casing 30. An outlet 38 having a plurality of openings is provided on a side surface of the upper casing 30.

During operation, first, water is poured into the lower casing. The depth of the water, the water surface is below the lower disk 10,
In addition, the opening in the lower casing of the water conduit 32 has a depth sufficient to be immersed in water. In this state, the motor 28
To rotate the rotating body. Then, the upper casing 30 and the lower casing 34 do not rotate, but only the rotator suspended from the upper casing 30 rotates. The rotation speed is not particularly limited, but is usually 500 to 3000
rpm is preferred. When the rotating body is rotated, the headrace 3
2 of water entering from the open end which opens in the lower casing 34 in the water conduit 32, the water penetrates to inside the water container 14, water is supplied into the water container 14. The supplied water reaches the partition 12 by centrifugal force, proceeds outward (when the water container is spiral as shown in the drawing) and upwards while forming a film on the partition 12, Once there, the water flows out into the spiral path 20 . The outflowing water proceeds toward the outside of the spiral while being pressed against the inner surface of the rib 18 by centrifugal force. When the water reaches the first concave portion 22 , the water accumulates in the concave portion due to the centrifugal force. As the water flows out from the water outlet 16 one after another, the first concave portion 22 alone cannot accommodate the water, and the water reaches the second concave portion 22 along the inner surface of the rib and accumulates there. Further, when water flows out from the water outlet 16, the water travels along the inner surface of the rib to reach the third concave portion 22 , where it is stored. In this manner, water accumulates in the plurality of recesses 22 one after another from the base end side of the spiral near the water outlet 16. For maximum humidification efficiency, it is preferred that water be pooled in the recess 22 near the extreme end of the swirl, but it is not a problem if some recesses 22 are empty. When the total amount of water flowing out of the water outlet 16 is larger than the total volume of the recess 22 , the water scatters from the end of the spiral passage 20 ,
Is provided at a position higher than the end opening of the spiral passage 20 , the water scattered from the end of the passage 20 hits the inner side wall of the lower casing 34 and is returned to the lower casing 34.

On the other hand, due to the centrifugal force, the indoor air is sucked from the suction port 36, enters the water container 14 , and the water outlet 1
6 and flows through the spiral passage 20 . At this time, the air flows toward the end of the spiral while being in contact with the water stored in the plurality of recesses 22 , so that the air is humidified. The humidified air is discharged from an outlet 38 provided in the upper casing 30.

In the above embodiment, the spiral passage is used.
As means for supplying water to or near the base end of 20 ,
The water conduit 32, the water container 14, and the water outlet 16 are formed. However, the water supply means in the present invention is not necessarily limited to this. For example, in the illustrated example, the water conduit 32 is provided, but the water conduit 32
Need not necessarily be provided (in this case, there is no hole at the bottom of the water container 14 ). In this case, the water is manually injected into the water container 14 from the suction port 36 before the operation starts, and the water previously stored in the water container 14 at the time of operation is supplied from the water outlet 16 to the base of the spiral passage. Supplied to the end. Therefore,
In this case, the water container 14 and the water outlet 16 constitute a water supply unit. Further, in the illustrated example, the water supply means includes a water container 14 constituted by a closed partition 12 and a water outlet 16 formed on an upper portion of the partition 12,
These are not particularly necessary. If the water guide pipe 32 is opened in a region inside the winding at the most center side of the rib 18, the water flowing into the lower disk 10 from the water guide pipe 32 is centrifugally generated. Since it moves along the inner surface of the rib 18, water can be supplied to the base end of the spiral passage.

Further, in the above embodiment, the water outlet 16 and the spiral passage communicating therewith are respectively one. However, a plurality of water outlets are provided at different positions of the water container, and each water outlet has a base end. Can also be formed in separate spiral passages, respectively. For example, a total of two positions are opposed to each other on the water container 14 , or a total of three positions are shifted by about 120 degrees.
A plurality of water outlets can be provided, and two or three spiral passages each having a base end communicating with each water outlet can be provided.
In this way, the number of turns per spiral must necessarily be smaller than in the case where one spiral is formed in terms of space, but for this reason, from the water outlet to the end of the spiral passage. Becomes shorter, and as a result,
The pressure loss is reduced, while the number of the recesses 22 can be formed as long as one spiral is formed by adding a plurality of spiral ribs, so that when a motor having the same output is used, This is preferable because the flow rate of air increases and the humidification efficiency increases.

Further, in the illustrated example, of ribs 18, but the portion and the recess 22 except for the portion forming the concave <br/> portion 22 are substantially the length of the same extent, the recess 22 (The length of the recess 22 and the portion other than the recess 22 is shortened), the total amount of water stored in the recess can be increased, and the humidification efficiency can be further improved. Further, the bottom of the spiral passage 20 (that is, the lower disk 1
0) may be provided with a plurality of drain holes. In this way, the centrifugal force at the time of stopping the water accumulated on the passage 20 when the operation is stopped (operation does not work, the water in the recess 22 passage 2
0 ) can be drained into the lower casing.

Further, the spiral rib 18 may be provided with a number of small through holes penetrating the rib 18 in the radial direction of the spiral. In this way, water moving along the inner surface of the rib 18 and moving to the end of the spiral enters these through holes, penetrates the rib 18, and extends one outer spiral passage 2.
0 is discharged, by scattering bursting of water upon exiting the through hole, mist is generated, so the generated mist is vaporized in the spiral passage 20, the indoor air more efficiently It becomes possible to humidify.

[0015]

As described above, according to the present invention, a humidifier capable of efficiently humidifying air without using a water absorber is provided for the first time. Since the humidifier of the present invention does not use a water absorbing body, there is no fear that the germs propagated in the water absorbing body are scattered. According to the present invention, since humidification can be performed efficiently, it is possible to reduce the size of the device, for example, to a small humidifier that can be easily carried around 10 to 20 cm in radius and 3 to 20 cm in thickness. Particularly suitable.
