Description

  The present invention relates to a mist generator that generates humidified air containing nanometer-size mist and negative ions by rotating a rotating body installed in a water storage chamber.

  Conventionally, in this type, the lower part is submerged in the water of the water storage chamber, and the water in the water storage chamber is pumped up by centrifugal force when the cylindrical rotating body pivotally supported by the drive motor and the drive shaft rotates to rotate the rotating body. The water that is pushed up along the outer wall and the inner wall of the rotating body is scattered around the outer wall of the rotating body, and the water that is pushed up along the inner wall of the rotating body is formed at the upper end of the rotating body. It is scattered from the air outlet to the surroundings, and is located at a predetermined interval on the upper outer periphery of the rotating body, and passes through a porous body that crushes water scattered from the air outlet by a porous portion made up of many slits, punching metal, etc. This makes it possible to generate nanometer-sized mist because the water is made into a mist, and the water in the mist collides with a collision body installed on the outer periphery of the porous body. And occurred in large quantities Humidified air containing mist and negative ions Roh meter size was released into the chamber by the blower fan. (For example, Patent Document 1)

  However, in this conventional system, not all of the water that collided with the collision body is made ultrafine, and water droplets that are not made ultrafine are also generated at the same time. It may drop into the reservoir due to gravity or air flow due to the mass of the water droplets.Since the water drops from the impactor drop into the water in the reservoir, a noise is generated. There was room.

In order to solve the above problems, in the present invention, a water storage chamber for storing water, a rotary body that is installed in the water storage chamber and pumps water by rotating, and a rotary body that is pivotally supported by the drive shaft and a predetermined shaft. A drive motor that is driven to rotate at a rotational speed; a spout that discharges the pumped water formed in the rotating body in an outer circumferential direction; and a porous portion that is installed on the outer periphery of the rotating body and crushes the water scattered from the scattering port. a porous body having, a collision body water which are disposed on the outer periphery of the porous body be crushed collides to form a cutout portion having a leg immersed in water of the water storage chamber to said impactor, said missing The part is formed with a hook connected to the leg with a downward slope with respect to the same direction as the rotation direction of the rotating body .

This invention forms a missing part with a leg immersed in the water of the water storage chamber in the collision body, and forms a hook connected to the leg with a downward slope in the same direction as the rotation direction of the rotating body in the missing part. As a result, water droplets are guided along the ridge that descends and inclines in the same direction as the swirling flow generated when the rotating body is driven to rotate by the drive motor, and guided into the water in the water storage chamber through the legs. Silence is improved without water drops dripping into the water storage chamber.

Next, the structure of the collision body 13 and the flow of water droplets in this embodiment will be described in detail with reference to FIGS.
First, the colliding body 13 is formed with a plurality of left and right asymmetric arch-shaped missing portions 32 that are cut out by a predetermined area, and the missing portions 32 are formed with legs 33 that have a length soaking in the water of the water storage chamber 5. And a flange 34 connected to the leg 33 and formed so as to have a downward slope at a predetermined angle with respect to the same direction as the direction in which the rotating body 9 is rotationally driven during the mist operation.

  Since the missing part 32 is formed in the collision body 13, the rotating body 9 is rotationally driven during the mist operation so that water droplets adhere to the collision body 13. Is applied to the water storage chamber 5 through the legs 33 of the missing portion 32 and the water droplets are prevented from dripping from the collision body 13 into the water storage chamber 5. It is possible to prevent the sound generated by dripping water droplets.

  Further, since the eaves 34 are inclined downward in the same direction with respect to the direction in which the rotating body 9 is driven to rotate, the rotating body 9 is driven to rotate during the mist operation, and a swirling flow is generated around it. A force is applied to the water droplets adhering to the body 13 to move in the same direction as the rotation direction of the rotating body 9, and the water droplets adhering to the colliding body 13 descends along the descending slope of the ridge 34 to the end of the ridge 34 Since the reached water droplet is guided into the water storage chamber 5 through the leg 33, it is possible to suppress the water droplet from dripping from the ridge 34 of the missing portion 32, and to prevent the sound generated by the dripping of the water droplet.

  As described above, a plurality of missing portions 32 are formed in the collision body 13 installed on the outer periphery of the rotator 9, so that the rotator 9 is driven to rotate during the mist operation, and water droplets refined by the porous body 12 collide. Even if the adhered water droplets adhere to the body 13 and become larger and descend downward, the water droplets are guided from the collision body 13 to the water storage chamber 5 through the legs 33. Silence can be secured without dripping.

  Further, by forming the flange 34 that slopes downward in the same direction as the direction in which the rotating body 9 is driven to rotate so as to be connected to the leg 33, the swirl flow generated when the rotating body 9 is driven to rotate is generated. Because the dredging 34 is inclined downward in the same direction, even if water droplets are generated in the mist operation, the dripping 34 moves along the dredging 34, and the water drops reaching the end of the dredging 34 are transmitted along the legs 33 to the water storage chamber 5. Since it is guided into the water, water droplets do not drop from the colliding body 13, and quietness can be ensured.

  In the present embodiment, the description has been given of the case where the missing portion 32 is formed in an asymmetrical arch shape. However, the present invention is not limited to this, and for example, as shown in FIG. The missing portion 32 may be formed in a substantially sector shape in which the end of the curve reaches the water in the water storage chamber 5, as long as the water adhering to the collision body 13 can be reliably guided to the water in the water storage chamber 5.

  Moreover, about the area of the missing part 32 and the inclination angle of the eaves 34 that are inclined downward, it adheres to the collision body 13 within a range that does not hinder the blown amount of nanometer-sized mist and negative ions that are micronized during mist operation. The numerical value can be freely changed while the water droplets can be efficiently guided to the water storage chamber 5.

  Note that the structure of the rotating body 9 and the shape of the missing portion 32 formed in the collision body 13 used in the present embodiment are presented as examples, and are not intended to limit the scope of the invention. The invention can be implemented in various forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
