[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a humidifying device for keeping a room at a desired humidity and moisturizing human skin and throat.
[0002]
[Prior art]
There are two types of humidifiers: a heating type that heats water to boil and evaporates, an ultrasonic type that emits water in a mist form by ultrasonic waves, and a vaporization type that vaporizes moisture on the surface of the humidifying element by blowing air. Conventionally, various products have been provided (see, for example, Patent Document 1). However, since the mist generated using each of the above methods is a micro size having a particle size of about several μm, it can enter into the gaps on the surface of the stratum corneum of the human body having a width of several tens of nanometers, It was difficult to disperse far away. For this reason, it is difficult for conventional humidifiers to sufficiently moisturize the skin and throat of the human body, and when the amount of humidification is increased in order to provide sufficient moisturization, the human body can absorb it completely. Excessive mist is supplied into the air and the humidity is increased until it is uncomfortable for the user, excessive mist is condensed on the walls and windows and the room is submerged. The occurrence of various problems was inevitable, such as promoting the occurrence.

[0012]
Next, the small diameter mist generating part 31 will be described in detail with reference to FIGS. The small-diameter mist generating unit 31 of the present example generates nano-sized mist (hereinafter referred to as small-diameter mist) M ₂ having a particle diameter of 1 to several tens of nm using the electrostatic atomization mechanism 44. is there. Specifically, the electrostatic atomization mechanism 44 is a plurality of rod-shaped members made of a porous body, which transports moisture from the proximal end side to the distal end side by capillary action, and the water transport member. A water application electrode 41 that holds the voltage 40 and applies a voltage to the water that the water conveyance member 40 conveys, a counter electrode 42 that faces the tip of the plurality of water conveyance members 40, and water application A high voltage application unit (not shown) that applies a high voltage between the electrode 41 and the counter electrode 42, and a cylindrical member that holds the water application electrode 41 and the counter electrode 42 therein, and the tip of the water transport member 40 And a housing portion 43 having a small-diameter mist discharge port 18 opened on the front side. When a high voltage is applied to the water application electrode 41 by the high voltage application unit in the small-diameter mist generating unit 31 having the above-described configuration, the water conveyed by the water conveyance member 40 includes the tip of the water conveyance member 40 and the counter electrode 42. An electrostatic atomization phenomenon occurs due to a high-voltage electric field generated during the period. That is, the water of the water transport member 40 is discharged toward the counter electrode 42 as the highly charged small diameter mist M ₂ and discharged from the small diameter mist discharge port 18. In addition, 49 in FIG. 9 is an ionization needle. A high voltage is applied to this needle, and negative ions are generated by corona discharge between the counter electrode 42, thereby facilitating the electrostatic atomization phenomenon. It is.
[0013]
The casing 43 is divided into a water aggregating part 45 that is a part on the proximal end side of the water transporting member 40 and an atomization part 46 that is a part on the leading end side of the water transporting member 40 with the water application electrode 41 interposed therebetween. Is done. A mist connection pipe 47 extends downward in the water aggregation portion 45, and as shown in FIG. 6, the lower end opening of the mist connection pipe 47 is inserted into the discharge pipe 16 to be connected in communication. A part of the large diameter mist M ₁ generated by the large diameter mist generating part 30 is introduced into the water aggregating part 45 through the discharge pipe 16 and the mist connecting pipe 47 and aggregated in the water aggregating part 45. The obtained water is supplied to the proximal end side of the water conveyance member 40. Here, in general, in a mechanism using an electrostatic atomization phenomenon, when the supplied water is tap water or the like in which cations such as Ca and Mg are dissolved, the cations are also sucked up together with the water. However, in the humidifying apparatus 1 of this example, water is once evaporated by heating, because it reacts with CO ₂ in the air and precipitates and adheres as CaCO ₃ or MgO to prevent the generation of electrostatic atomization. in terms of the by very low mist state of the content of cations such as Ca and Mg, since the water obtained which was re-agglomerate so as to supply the water conveying member 40, Mizu搬feed member 40 It is possible to prevent CaCO ₃ , MgO and the like from being deposited on the surface.
[0014]
Further, a ventilation connection port 48 is opened downward in the atomizing section 46, and as shown in FIG. 6, the upper end portion 17b of the blower pipe 17 in which the small diameter mist side blowing port 12 is opened is connected by ventilation. A part of the air sent by the motor fan 2 is sent into the front of the front end of the water transport member 40 through the small-diameter mist side air blowing port 12 and is discharged from the small-diameter mist discharge port 18 by being inserted into the port 48. It is. The small diameter mist generating portion 31 is disposed from the housing 20 so that the tip end portion of the housing portion 43 where the small diameter mist discharge port 18 is opened protrudes slightly from the housing 20 and is thus discharged from the small diameter mist discharge port 18. Air is discharged to the outside of the humidifier 1.
[0015]
Thus, in the humidifying device 1 having the above-described configuration, when the large-diameter mist generating unit 30 and the small-diameter mist generating unit 31 are operated in a state where the water supply unit 32 (that is, in the water supply tank 8) is filled with water. Here, the blower unit 29 is not operated. The case where it is operated will be described later), and operates as follows. That is, the water supplied from the water supply unit 32 to the large-diameter mist generating unit 30 is heated and evaporated by the heating mechanism 21 to generate a micro-sized large-diameter mist M ₁ having a particle size of several μm or more. throughout _the mist supply passage 22 (i.e. the mist guide tube 14 and the discharge pipe 16), ejected in the front direction from the large-diameter droplet mist discharge port 15 provided in front of the humidifier 1. At the same time, the small-diameter mist generating unit 31, a part of the large-diameter droplet mist M ₁ from intermediate path of the mist supply passage 22 caused by the large-diameter droplet mist generation unit 30 is supplied to condense the large-diameter mist M ₁ Based on the obtained water, an electrostatic atomization mechanism 44 generates a nano-sized small-diameter mist M ₂ that is highly charged and has a particle diameter of 1 to several tens of nanometers, and this small-diameter mist M ₂ is placed in front of the humidifier 1. It discharges from the provided small diameter mist discharge port 18 in the front direction.
[0016]
The gap on the surface of the stratum corneum of the human body is several tens of nanometers. However, in the humidifying apparatus 1 of this example, the nano-sized small diameter is 1 to several tens of nanometers using the electrostatic atomization mechanism 44 as described above. Since the mist M ₂ is discharged, the small diameter mist M ₂ supplies moisture to the back of the gap on the stratum corneum surface. Also, small diameter mist M ₂ is liable to scatter from it is a nano-sized, which be attentive to the distant riding circulating air flow chamber, and excellent in adhesion performance to the skin because of its high charge Is. In addition, the humidifier 1 of the present embodiment, since discharging the large-diameter droplet mist M ₁ using the heating mechanism 21, it is easy to maintain and is raised to the desired humidity an entire room in a short time. In other words, the humidifier 1 of this embodiment, by discharging the large-diameter droplet mist M ₁ and the small-diameter mist M ₂ at the same time, by exposure of the large-diameter mist M ₁ to a short time with saturated closer to human skin and throat in terms of supplying the water, you can go to further increase the water content by exposure of the small diameter mist M _2. Therefore, the user stays at a proper humidity without causing problems such as discomfort to the user, flooding of the room due to condensation on walls and windows, and promotion of mold. Sufficient moisture can be given to the skin and throat of the person in the place.
[0017]
Here, the small diameter mist M ₂ is attracted to the ion wind generated by the electric field of the electrostatic atomization mechanism 44 and diffused to the outside from the small diameter mist discharge port 18. There may be a case where the ion wind alone is not sufficient to be scattered all over the room. On the other hand, in the humidifying device 1 of this example, the large-diameter mist discharge port 15 and the small-diameter mist discharge port 18 are provided close to each other so as to open in the front direction, and the large-diameter mist Since the discharge port 15 is provided so as to be positioned below the small-diameter mist discharge port 18, the high-temperature large-diameter mist M ₁ heated and boiled by the heating mechanism 21 and vigorously discharged from the large-diameter mist discharge port 15 is The direction is changed from immediately after discharge to an obliquely upward direction so as to pass in front of the small-diameter mist discharge port 18 close to the upper side. Then, attract small diameter mist M ₂ where high-temperature flow of the large-diameter droplet mist M ₁ is discharged from the small-diameter mist discharge port 18 is to reliably supply the small-diameter mist M ₂ to every corner of the room.
[0018]
Further, in the humidifying device 1 of this example, the moisture supplied to the small diameter mist generating unit 31 is _one of the large diameter mist M ₁ generated by the large diameter mist generating unit 30 based on the water supplied from the water supply unit 32. In other words, the large diameter mist generating section 30 and the small diameter mist generating section 31 are supplied with water from a common water supply section 32. Therefore, the number of parts required for water supply is small, and it can be provided in a compact and inexpensive manner. Furthermore, since the water supply tank 8 needs to be replaced only once, there is no need for replacement.
[0019]
Next, in the humidifying device 1, the case where the blower 29 is operated together with the operation of the large diameter mist generating unit 30 and the small diameter mist generating unit 31 (that is, the case where the motor fan 2 is operated) will be described. In this case, as described above, the air sucked from the filter case 26 and purified by the operation of the motor fan 2 is discharged from both sides of the large diameter mist side air outlet 11 and the small diameter mist side air outlet 12 of the air pipe 17. The air discharged from the large diameter mist side air outlet 11 passes through the discharge pipe 16 and is discharged to the outside from the large diameter mist side air outlet 15, and the air discharged from the small diameter mist side air outlet 12 generates a small diameter mist. It is discharged from the small diameter mist discharge port 18 of the portion 31 to the outside. By the blowing unit 29 the flow of air discharged from the large-diameter droplet mist discharge port 15 to the outside, the large-diameter droplet mist M ₁ strongly attracted outward similarly discharged from the large-diameter droplet mist discharge port 15 Further, the flow of air discharged from the small-diameter mist discharge port 18 to the outside by the blower 29, is to strongly attract small mist M ₂ similarly discharged from the small-diameter mist discharge port 18 outwardly . Thus, the humidifying device 1 of this example has a structure in which the large-diameter mist generating unit 30 and the small-diameter mist generating unit 31 are supplied with the cited wind from the common air blowing unit 29, and are required for the wind supply. The number of parts is small, and it can be provided in a compact and inexpensive manner.
[0020]
In the present embodiment, by as a large-diameter droplet mist generation unit 30 using the heating mechanism 21, the indoor temperature and the air supplied with the large-diameter droplet mist M ₁ and the large-diameter mist M ₁ to a high temperature However, the large-diameter mist generating unit 30 is not limited to the one using this, and water is atomized by ultrasonic waves. It is also possible to use a mechanism using an ultrasonic mechanism that emits light or a structure that vaporizes moisture on the surface of the humidifying element by blowing air. In this case, since the indoor temperature is not increased by heating, there is an effect that discomfort to the user is prevented in summer.
[0021]
In the present embodiment, by setting the opening direction of the large-diameter droplet mist discharge port 15 and the small-diameter mist discharge port 18 in the front direction, the ejection direction of the large-diameter droplet mist M ₁ and the small-diameter mist M ₂ as forward together, especially humidified Although it is possible to efficiently supply moisture to a person in the vicinity of the apparatus 1, the opening directions of the large-diameter mist discharge port 15 and the small-diameter mist discharge port 18 are not limited to this. It may be an opening. In this case, the discharge direction of the large-diameter droplet mist M ₁ and the small-diameter mist M ₂ both become upward, relatively easily can produce circulating air flow in a room, it can be supplied to the water even for more distant human It becomes. Furthermore, as the large-diameter mist discharge port 15 and the small-diameter mist discharge port 18, a discharge port that opens forward and a discharge that opens upward are provided, respectively, and the large-diameter mist discharge port 15 and the small-diameter mist discharge port 18 are opened. It is also preferable that the direction can be switched between the front direction and the upper direction. In this case, if the opening direction is switched corresponding to both the situation where the person is in the vicinity of the humidifier 1 and the situation where the person is far away, In any situation, water can be sufficiently supplied.
