41 is a mist generator provided in the upper front part of the column 4. The mist generator 41 includes an electrostatic atomizer 42 attached to an insulating table 41A for generating mist of a picometer size (here, picometer = pm = ^10-12 meters), and use of the mist generator 41. The LED lamp 43 serving as a display means that is sometimes lit is covered with a common shell 44.

  Among them, the electrostatic atomizer 42 includes a water tank 45 as a liquid supply means, a discharge electrode 46 as one electrode through which water in the water tank 45 is conveyed by capillary action, and is opposed to the discharge electrode 46. A counter electrode 47 (not shown), which is the other electrode provided, and a voltage applying means 48 (not shown) for applying a high voltage between the discharge electrode 46 and the counter electrode 47 are provided. Openings 49 and 50 for forming an air flow path are provided in the outer shell 44 so as to be respectively located on the front surface and the upper surface of the electrostatic atomizer 42.

  The discharge electrode 46 is made of an aggregate of porous polyester having countless pores smaller than the pores of porous ceramics, for example, and the tip is formed in an arc shape and the base end side is connected to a water tank. One or a plurality of rod-shaped bodies. The discharge electrode 46 has water absorption due to the porous structure, and has a structure capable of sucking the liquid (water) inside the water tank 45 from the base end connected to the water tank 45 to the tip.

  The LED lamp 43 is soldered to a printed circuit board 51 below the mist generator 41, and a pair of lead wires 52 provided for supplying power to the LED lamp 43 are also soldered to the printed circuit board 51. Connected. Further, above the LED lamp 43, a lamp display window 53 made of a vertically long translucent member as viewed from the front of the electric fan 1 is provided. When the mist generator 41 is used, the light from the LED lamp 43 is transmitted to the lamp display window 53. It is diffused as a whole and is lit and displayed from the front of the mist generator 41.

  Next, the operation of the above configuration will be described. When the mist generator 41 is brought into an operating state by an operation switch (not shown), mist M1 (see FIG. 3) is generated inside the mist generator 41.

  Here, the generation of picometer-sized mist M1 by the electrostatic atomizer 42 will be described. In the electrostatic atomizer 42, voltage application means is provided between the discharge electrode 46 and the counter electrode 47 (not shown). When a voltage is applied by 48 (not shown), charge concentration occurs at the tip of the discharge electrode 46, the water sucked from the water tank 45 to the tip of the discharge electrode 46 by capillary action and the counter electrode 47 ( Water is charged due to the Coulomb force acting on it (not shown), and when this Coulomb force exceeds the surface tension of water, water repeats splitting (Rayleigh splitting), and OH radicals (hydroxy radicals or hydroxyl radicals) ) Or the like (radical or free radicals, free radicals) and the like.

  In this case, by forming the discharge electrode 46 from an aggregate of porous polyester having countless pores smaller than the pores of the porous ceramic, for example, as described above, water is very small by capillarity. It is sucked up so as to ooze out from the hole to the tip of the discharge electrode 46. Further, the discharge electrode 46 and the counter electrode 47 (not shown) are formed by forming the tip of the discharge electrode 46 in an arc shape so that the opposing area of the discharge electrode 46 facing the counter electrode 47 (not shown) is large. ), The concentration of charges on the tip of the discharge electrode 46 when a voltage is applied is reduced. Then, by reducing the concentration of charge at the tip of the discharge electrode 46, water is gradually split with a weak charge to generate a picometer-sized mist M1 having a finer particle diameter than the nanometer size. Is possible.

  The mist M1 generated by the electrostatic atomizer 42 of the mist generator 41 in the present embodiment is originally highly diffusible even in the case of a nanometer mist generated by a conventional mist generator. Although the diffusibility was improved by riding on the flow of air to be blown, the mist M1 has a particle size of picometers, so that it becomes easier to ride the air flow and the diffusivity is improved. Therefore, depending on the active species which are radicals (radical or free radicals, free radicals) such as OH radicals (hydroxy radicals or hydroxide radicals) contained in the picometer-sized mist M1 generated by the electrostatic atomizer 42, By effectively utilizing the sterilization / deodorization function for floating components in indoor air and deposits on indoor walls, Compared with nanometer-sized mists, effective and remarkable sterilization and deodorization can be performed over a wider range.

  Further, during the operation of the mist generator 41, the LED lamp 43 is turned on, and diffused light is displayed from the front side of the mist generator 41 through the lamp display window 53.

  When the fan 12 of the blower 2 is rotated in such a state, convection is generated by the fan 12 and wind is sent out toward the front of the fan 12. At this time, the mist generator 41 immediately below the blower 2 passes the air F taken from the opening 49 in the front of the electrostatic atomizer 42 to the electrostatic atomizer 42 in the mist generator 41. Thus, an air passage is formed that is sent out from another opening 50 on the upper surface of the electrostatic atomizer 42. As a result, the mist M1 generated in the electrostatic atomizer 42 does not stay in the mist generator 41 but rides on the air F flowing in the mist generator 41 and is delayed from the opening 50 toward the blower 2. As a result, the wind containing a large amount of mist M1 can be continuously sent from the front of the fan 12.

  The mist generator 41 is provided at a position where the mist M1 generated by the electrostatic atomizer 42 is easy to get on the convection of the fan 12 and easily appealed as the fan 1 with a mist generating function, that is, at the upper front portion of the column 4. Is preferred. This is because, for example, when the mist generator 41 is mounted on the base 3, the mist M1 is difficult to ride on the convection of the fan 12, and the mist M1 is difficult to diffuse outside. Further, although the rear portion of the fan 12 is a position where the mist M1 is relatively easily diffused to the outside, in this case, the appeal of the provision of the mist generator 41 is low, and the commercial value is not sufficiently transmitted to the user. Because there is a fear.

  Thus, the electric fan 1 is equipped with the mist generator 41 with respect to the electric fan 1 which especially supports the air blower 2 on the upper part of the support | pillar 4. FIG. In this case, since the electric fan 1 originally has a function of sending out the wind, if the mist generator 41 is mounted on the electric fan 1, the mist generator 41 is utilized by utilizing the flow (convection) of the wind generated by the blower 2. The mist M1 generated in 41 can be discharged to the outside of the electric fan 1 that is a device.

  Moreover, since the mist generator 41 is provided in the support column 4, the mist M1 generated by the mist generator 41 can easily ride on the convection of the blower 2 above the support column 4, and the mist M1 can be effectively diffused. Can do. In this case, as described above, the mist generator 41 can be diffused more effectively if the mist generator 41 is provided at a position near the blower 2 of the support column 4, and the mist generator 41 is provided on the front side of the electric fan 1. It is possible to increase the PR degree of a product as a device with a mist generating function.

  Furthermore, the electrostatic atomizer 42 to which a high voltage for generating the mist M1 is applied is covered with an outer shell 44 to form a mist generator 41, and is positioned on the front and upper surfaces of the electrostatic atomizer 42. Openings 49 and 50 are formed in the outer shell 44, respectively.

  In this way, in addition to being able to cover the electrostatic atomizer 42 with the outer shell 44, inside the mist generator 41, wind is taken in from the opening 49 located in front of the electrostatic atomizer 42. Then, an air passage is formed through which the wind containing the mist M1 is sent toward the blower 2 from the opening 50 located on the upper surface of the electrostatic atomizer 42. Therefore, the mist M1 generated by the mist generator 41 can be diffused outside without waste.

  As described above, in the present embodiment, the blower 2 serving as the blower and the mist generator 41 serving as the mist generator 41 that generates the picometer-sized mist M1 are provided, so that the pico generated by the mist generator 41 is generated. To active components such as radicals (radical or free radicals, free radicals) such as OH radicals (hydroxy radicals or hydroxide radicals) contained in metric Mist M1 By effectively utilizing the sterilization / deodorization function for the adhering substances, it is possible to perform effective and remarkable sterilization / deodorization over a wider range than the conventional mist of the specified (nanometer) size. It is.

  Next, a second embodiment of the electric fan of the present invention will be described with reference to FIG. Note that portions corresponding to those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

Along with the atomizing device 42, there is provided a second electrostatic atomizing device 64 for generating nanometer-sized mist M2 as shown in the conventional example. The second electrostatic atomizer 64 is arranged in the mist generator 41 in the same state as the first electrostatic atomizer 42 in the first embodiment, and the detailed description thereof will be given in the first embodiment. It shall be omitted with an example.

  In the above configuration, when the mist generator 41 is operated, the inside of the mist generator 41 takes in air from the opening 49 located in front of the electrostatic atomizer 42, and the electrostatic atomizer 42, 64, which is a mixture of mists M1 and M2 having different particle sizes from picometer size to nanometer size, is sent out toward the blower 2 from the opening 50 located on the upper surface of 64. It spreads.

  With respect to the scattering range of the mists M1 and M2 diffused by the blower 2 of the electric fan 1, a picometer size having a particle diameter smaller than that of the nanometer mist M2 due to the difference in the particle diameters of the mists M1 and M2. Compared with the nanometer-sized mist M2, the mist M1 of the mist M1 is easy to ride on the air flow and spreads more widely. Therefore, the mists M1 and M2 having different scattering ranges with different particle diameters are discharged from the electric fan so that they are diffused uniformly throughout the room.

  In this case, the mist M1 containing active species such as radicals (radical or free radicals, free radicals) such as OH radicals (hydroxy radicals or hydroxide radicals) by diffusing the mists M1 and M2 uniformly throughout the room over a wide range. , M2 enables effective and remarkable sterilization / deodorization by effectively utilizing the sterilization / deodorization function for floating components in indoor air and deposits on the wall of the room.

  As described above, in this embodiment, the mist generator 41 has a nanometer size having a particle diameter larger than the picometer size as a mist having a diameter different from the picometer size mist M1 and the picometer size mist M1. By discharging the mist M2 to the outside, the mists M1 and M2 having different scattering ranges with different particle diameters are discharged from the electric fan 1, so that the mists M1 and M2 are evenly diffused in the room over a wide range. In this case, by effectively providing the mists M1 and M2 indoors over a wide range, effective and remarkable sterilization and deodorization can be performed over a wide range.

  Further, in common with each of the above embodiments, an opening 50 is provided as an outlet for discharging the mist from the mist generator 41 to the outside so as to open above the mist generator 41 so as to face the blower 2. ing. In this way, the air that has passed through the mist generator 41 is discharged to the outside from the opening 50 that opens upward, so that the mist does not stay in the mist generator 41 but flows into the air flowing through the mist generator 41. It can be put on and sent out from the opening 50 without delay.

  In addition, this invention is not limited to the said Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, although the electrostatic atomizer 42 provided with the counter electrode 47 (not shown) is described in the first embodiment, the counter electrode 47 is not always necessary, and a high voltage with respect to the ground potential is applied to the discharge electrode. As long as it is applied to 46, electrostatic atomization is performed. Further, the material, shape and configuration of the discharge electrode 46 and the method for supplying water to the discharge electrode 46 can be changed as appropriate. In order to generate the mists M1 and M2 having different particle diameters in the second embodiment, the first electrostatic atomizer 42 for generating the picometer-sized mist M1 and the nanometer-sized mist M2 are generated. The second electrostatic atomizer 64 has a structure having a second electrostatic atomizer 64. However, a single electrostatic fog having the performance of the first electrostatic atomizer 42 and the second electrostatic atomizer 64 is provided. It is also possible to use as a device.
