[Embodiment 1]
Hereinafter, embodiments of the present invention will be described in detail.

  1-8 has shown the humidification apparatus 100 in Embodiment 1 of this invention. First, the overall configuration of the humidifier 100 will be described with reference to FIGS.

  The humidifier 100 has a main body 1 having a bell-shaped cross-sectional shape with an open rear side. A rear panel 3 having an air inlet 21 formed thereon is attached to the back surface of the main body 1. A front panel 4 is attached to the front surface of the main body 1. The main body 1, the rear panel 3, and the front panel 4 are all made of resin, and an outer member that forms the appearance of the humidifying device 100 is formed by them.

  An operation unit 18 having a plurality of buttons, LEDs, and the like is provided on the upper surface of the main body 1, and exhaust ports 20 having a large number of openings are formed on the left and right side surfaces of the main body 1. The exhaust port 20 is formed so as to surround the outer periphery of the fan 6 described later. The space inside the main body 1 is closed except for the exhaust port 20 and the intake port 21 by closing the rear panel 3 and the front panel 4.

  In the main body 1, a fan 6 having a plurality of blades 5 arranged radially, a blower motor (first drive mechanism) 7 that rotationally drives the fan 6, and a cylindrical vaporization filter 11 are disposed. ing.

  The blower motor 7 is arranged so that the axial direction of the rotary shaft 8 coincides with the front-rear direction of the main body 1. The fan 6 is composed of a turbo fan or a sirocco fan that sucks air from its side and discharges air from its outer periphery, and a rotating shaft 8 of the blower motor 7 is fixed at the center.

  The vaporization filter 11 is an annular member, and is arranged on the outer periphery of the fan 6 so as to be rotatable in a non-contact state. The vaporization filter 11 is attached to a filter case 31 as a filter support formed in a drum shape so that a band-shaped filter material 32 as a filter body is wound around the filter case 31. The filter material 32 is formed by laminating a sewn body excellent in water retention performance, a fiber assembly excellent in water separation, and the like.

  Here, preferably, the rotation center axis 6A of the fan 6 is disposed above the rotation center axis 11A of the vaporization filter 11 (see FIG. 4). In this case, the rotation center shafts 6A and 11A are preferably arranged so as to be located on the same vertical plane. Further, the fan 6 is preferably configured to be driven to rotate in a direction opposite to the rotation direction of the vaporization filter 11, and the speed of the vaporization filter 11 is set to be lower than that of the fan 6.

  Further, in the main body 1, a tray 12 disposed below the vaporization filter 11, a water supply gear motor (not shown) for feeding water (liquid) to the vaporization filter 11, and a tank serving as a supply source of vaporized water (Not shown). A tank (not shown) is detachably disposed between the main body 1 and the front panel 4.

  The tray 12 includes a storage unit 27 that stores water supplied from a tank, and a water supply unit 37 that uses a water supply gear motor as a drive source. The water supply unit 37 rotates the vaporization filter 11 around the fan 6 by the rotational force of the water supply gear motor, and pumps up the water in the storage unit 27 using the rotation of the vaporization filter 11, thereby vaporizing the filter 11. The filter material 32 is supplied from the inside.

  Further, a mist generating unit 40 of the atomizing device is disposed in the main body 1. The atomizing device operates by operating the operation unit 18 during operation of the humidifying device 100, and discharges a fine mist having a fine particle diameter with a negative charge from the discharge electrode 42 of the mist generating unit 40. Although details will be described later, in the humidifying apparatus 100 of the present embodiment, the mist generating unit 40 includes the distal end portion of the discharge electrode 42 and is outside the vaporizing filter 11 in the main body 1. In this way, the generated fine mist can be diffused on a stream of wet air.

  In the above configuration, when the operation unit 18 is operated to start the operation of the humidifier 100, the blower motor 7 is energized, and the fan 6 rotates inside the main body 1. Thereby, the humidifying air is taken in from the rear side surface of the fan 6 through the air inlet 21. The humidified air that has been taken in passes through the vaporizing filter 11 while changing its direction in the outer circumferential direction of the fan 6 as shown by the arrow in FIG.

  During operation of the humidifier 100, the water supply gear motor is energized as necessary. Thereby, while rotating the vaporization filter 11, water is supplied toward the filter material 32 from the inside of the vaporization filter 11, and the filter material 32 is always in a state containing water. Therefore, the humidifying air that passes through the vaporizing filter 11 as the fan 6 rotates is deprived of moisture from the filter material 32 and is discharged as wet air to the exhaust port 20 formed on the side surface of the main body 1. .

  By reversing the direction of rotation of the fan 6 and the direction of rotation of the vaporization filter 11, the wind speed applied to the vaporization filter 11 can be increased. Further, by providing the rotation center position (6A) of the fan 6 above the rotation center position (11A) of the vaporization filter 11 (see FIG. 4), the exhaust speed from the upper side of the exhaust port 20 is increased and the exhaust gas is exhausted. Balance can be achieved by lowering the wind speed discharged from the lower side of the mouth 20.

  Next, the characteristic part regarding the humidification apparatus 100 is demonstrated in more detail with reference to FIG. 1, FIG. 5-FIG.

  As shown in FIG. 5, in the humidifier 100, when the fan 6 is rotated in the direction indicated by the arrow a, the air taken in from the rear side of the fan 6 flows as indicated by the arrow b. In consideration of such an air flow and an empty space in the main body 1, in the present embodiment, as shown in FIG. The mist generating part 40 of the atomizer is attached in the vicinity of the exhaust port 20. However, the position where the mist generating part 40 is attached and the number of attachments are not limited thereto.

  The atomizing device is carried on the surface of the discharge electrode 42 by applying a high voltage between the discharge electrode 42 having water retention provided in the mist generating unit 40 and a counter electrode (not shown). Water is electrostatically atomized to generate fine mist from the tip of the discharge electrode 42.

  The discharge electrode 42 is covered with a water retention material 43. The water retention material 43 takes in moisture from the air that has passed through the vaporization filter 11 and carries water on the surface of the discharge electrode 42. When the operation unit 18 is operated and a high voltage is applied between the discharge electrode 42 and the counter electrode (not shown) from the high voltage application unit (not shown), the concentration of charges on the tip of the discharge electrode 42 is concentrated. Occur. As a result, the Coulomb force acts between the water carried on the tip of the discharge electrode 42 and the counter electrode to charge the water, and when this Coulomb force exceeds the surface tension of the water, the water is split (Rayleigh split). By repeating, a fine mist having a particle diameter containing an active species such as radical (radical or free radical, free radical) such as OH radical (hydroxy radical or hydroxyl radical) is generated from the tip.

  As shown in FIG. 6, a plurality of discharge electrodes 42 are provided in a line. The mist generating unit 40 is mounted in the main body 1 so that the plurality of discharge electrodes 42 are arranged along the axial direction of the rotation shaft of the blower motor 7 (the rotation shaft of the fan 6) (see FIG. 1). . As described above, the discharge electrode 42 is disposed outside the vaporizing filter 11 in the main body 1 including its tip, and is disposed in a flow path of wet air.

  Thereby, fine mist is generated inside the main body 1, and the generated fine mist is put on the air flow together with the humid air discharged from the exhaust port 20 formed on the side surface of the main body 1. Can be diffused.

  Further, in order to diffuse the generated fine mist, it is a conventional means to apply wind to the portion of the discharge electrode 42 where the fine mist is generated, but when the water carried on the surface of the discharge electrode 42 is taken away by the wind, Fine mist cannot be generated. In the above configuration, since the wind that hits the portion where the fine mist is generated becomes the wind of wet air, the wind is unlikely to take water on the surface of the discharge electrode 42, and the discharge electrode 42 is prevented from drying (or suppressed) by the wind. can do.

  Further, as described above, in the configuration in which moisture is taken in from the air and carried on the surface of the discharge electrode 42, when the mist generating part 40 is disposed outside the main body 1, in a dry environment where the moisture in the air is small. Since water is not easily carried on the surface of the discharge electrode 42, fine mist cannot be generated as a result. However, by arranging the mist generating part 40 (discharge electrode 42) in the main body 1 in this way, moisture can be taken in from the moist air that has passed through the vaporization filter 11, so that it is not related to the state of indoor air. , Can be captured effectively.

  By the way, when the discharge electrode 42 is a wet air flow path in the main body 1 and is disposed outside the vaporization filter 11, there is a possibility that the amount of water carried on the discharge electrode 42 becomes excessive. This is because water droplets (droplets) scattered from the vaporization filter 11 adhere to the discharge electrode 42. If too much water is carried on the discharge electrode 42, leakage occurs between the discharge electrodes 42 or leakage occurs, and the concentration of charges at the tip of the discharge electrode 42 does not occur, and fine mist is generated. It cannot be generated.

  Therefore, in the humidifying apparatus 100 of the present embodiment, as shown in FIG. 1, a prevention mechanism that prevents the occurrence of fine mist caused by water droplets (droplets) scattered from the vaporization filter 11, in other words, the vaporization filter 11. A shielding unit 50 is provided as a prevention mechanism for preventing the generation of fine mist from being inhibited by the more scattered water droplets adhering to the discharge electrode 42. The shield 50 covers the side of the discharge electrode 42 where water droplets are scattered.

  In the present embodiment, the shielding part 50 is slidably provided on the downstream side in the rotation direction of the fan 6 in the discharge electrode 42, and the wall-shaped member 51 is inclined toward the discharge electrode 42 by the air flow generated by the rotation of the fan 6. Consists of.

  As shown in FIG. 7, the wall-shaped member 51 is a J-shaped or L-shaped member whose lower end side is bent, and has a depth length equivalent to that of the mist generating portion 40. Such a wall-shaped member 51 is attached to the upper part in the upper end side main body 1 so that the upper end is freely swingable, and hangs down by its own weight (see FIG. 1).

  As shown in FIG. 8A, in a state where the fan 6 is not rotating, the wall-like member 51 hangs down due to its own weight, and when the fan 6 rotates, as shown in FIG. The airflow (wind) generated by the rotation of 6 inclines toward the discharge electrode 42 and covers the side of the discharge electrode 42 where water droplets are scattered. At this time, the tilting angle is in accordance with the strength of the airflow, and tilts as the airflow is stronger. It should be noted that although there is no problem even if it comes into contact with the support portion of the discharge electrode 42 of the mist generating portion 40, it is necessary to have a configuration that does not contact the discharge electrode 42. In the most inclined state, it is preferable to completely shield the tip of the discharge electrode 42 from the vaporization filter 11.

  Thereby, even if the discharge electrode 42 of the atomizer is a flow path of the humid air in the main body 1 and is disposed outside the vaporization filter 11, water droplets scattered from the vaporization filter 11 are applied to the discharge electrode 42. It is possible to prevent the adhesion and to generate fine mist from the tip of the discharge electrode 42 without any problem.

  The wall-like member 51 is made of the same resin as the main body 1 or the like, and may be slidably attached to the main body 1 via a shaft or the like. It is good also as a structure which inclines to the discharge electrode 42 side using property. Further, the shape of the wall-shaped member 51 is not limited to a J-shape or an L-shape, and may be an I-shape as shown in FIGS. 9 (a) and 9 (b). . However, when the surface of the filter material 32 of the vaporization filter 11 and the tip of the discharge electrode 42 are close to each other and the space for inserting a member for blocking the gap is small, it is preferable to have a J shape or an L shape.

  In addition, although the structure provided with the discharge electrode 42 which has water retention property was illustrated as an atomization apparatus, the discharge electrode is cooled using a Peltier device etc., a dew condensation is caused, and the discharge electrode carries water. An atomizer may be sufficient.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

  As shown in FIG. 10, the humidifying device 101 of this embodiment includes a wall-like member 52 that is oscillated by a oscillating mechanism (second drive mechanism) 53 as the shielding unit 50. Also, a humidity sensor 60 that detects the humidity in the main body 1 and a control unit that drives the peristaltic mechanism 53 in accordance with the humidity detected by the humidity sensor 6 to change the inclination of the wall member 52 to the discharge electrode 42. 61 is further provided.

  The shape of the wall member 52 is the same as that of the wall member 51. However, since it is not the structure which inclines to the discharge electrode 42 side by the effect | action of an airflow (wind), it is not suitable to comprise from the sheet | seat etc. which have elasticity.

  It has been found that the amount of water droplets (or the number of water droplets) scattered from the vaporization filter 11 depends on the humidity in the main body 1. The higher the humidity in the main body 1, the more water droplets are scattered and the water droplets are more likely to adhere to the discharge electrode 42.

  Therefore, the humidity in the main body 1 is detected by the humidity sensor 60, and the control unit 61 adjusts the inclination of the wall-shaped member 52 according to the detected humidity. When the humidity is low, there is almost no risk of water droplets scattering, so the inclination of the wall member 51 is set to 0 °. When the humidity is likely to cause water droplets to be scattered, the wall-shaped member 51 is tilted to have a tilt according to the humidity.

[Embodiment 3]
Another embodiment of the present invention is described below with reference to FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

  As shown in FIG. 11, the humidifying device of the present embodiment has an interval at which the prevention mechanism that prevents the occurrence of fine mist due to water droplets scattered from the vaporization filter 11 can generate fine mist even when the droplets are attached. Are a plurality of discharge electrodes 42. In other words, the prevention mechanism is realized by setting the distance between the discharge electrodes 42 in the mist generating unit 44 to a distance at which fine mist can be generated without problems even when droplets are attached to the discharge electrode 42.

  The distance between the discharge electrodes 42 is set based on an experiment or by simulation in consideration of the amount of water droplets adhering to the discharge electrode 42 under conditions where water droplets are scattered most.

  Thus, by setting the distance between the discharge electrodes 42 to a distance at which fine mist can be generated even when the droplets are attached to the discharge electrode 42, the problem of mist generation failure due to water droplets scattered from the vaporization filter 11 can be solved. This can be realized without adding new members. However, in this case, since the number of discharge electrodes 42 is smaller than that in the prior art, it is necessary to increase the number of mist generating portions 44 in order to generate a colleague's fine mist.

[Example 1]
FIG. 12 is a diagram illustrating an example of dimensions and positional relationships of the mist generating unit 40 and the wall-shaped member 51 that is the shielding unit 50 of the atomizing device mounted on the humidifying device 100 according to the first embodiment. The dimension of the support part 45 that supports the discharge electrode 42 in the mist generating part 40 is horizontal × high × depth: 12 mm × 15 mm × 61 mm, and the protruding distance of the discharge electrode 42 from the support part 45 is 5 mm. In this case, as the wall-like member 51 of the shielding part 50, a mist generation part 40 is obtained by bending a resin plate (thickness is arbitrary) of height x depth: 25 mm x 61 mm parallel to the longitudinal direction at a location 15 mm from the end. It is mounted 8 mm off. The attachment side is the downstream side in the rotation direction of the fan 6 with respect to the mist generating unit 40.

  By setting it as such a structure, the wall-shaped member 52 inclines about 20 degrees at maximum, and can interrupt | block the side where the water droplet in the discharge electrode 42 scatters.

[Example 2]
FIG. 13 is a graph illustrating an example of the inclination angle of the wall-shaped member 52 with respect to the humidity in the humidifying device 101 according to the second embodiment of the present invention. The control unit 61 adjusts the inclination of the wall member 52 according to the humidity in the main body 1. In the example of FIG. 13, the inclination is 0 ° until the humidity reaches 30%, the angle is 5 ° when the humidity is 30%, the angle at 50% is 10 °, and the angle is 20 ° when the humidity is 70% or more. To do.

  As the humidity sensor 60, for example, “HSU-07F5V3-N” manufactured by Hokuriku Electric Industry Co., Ltd. can be used. FIG. 14 shows the standard temperature and humidity characteristics of HSU-07F5V3-N.
