Description

  The present invention relates to an electrostatic atomizer that generates nano ion mist.

The electrostatic atomizer includes a water transport unit that transports water by capillary action, a water supply unit that supplies water to the water transport unit, and an application electrode that applies a voltage to the water transported by the water transport unit. A counter electrode positioned opposite to the water transfer unit, and a high voltage application unit that applies a high voltage between the application electrode and the counter electrode, and the water transfer by the high voltage applied by the high voltage application unit. the water retained in the front end parts is atomized toward the opposite electrode, Ru der those for generating nano-ion mist is mist having a strong charge at the nano size. Since the particle size of the nano ion mist is about 1 to several tens of nanometers and smaller than 70 nm, which is the size of the horny cells of the human body, the exposure of the nano ion mist causes moisture to reach the back of the stratum corneum surface. It is sufficiently replenished to obtain a high moisturizing effect.

However, since the conventional electrostatic atomizer described above has a structure including a water tank as a water supply unit for supplying moisture to the water transport unit, the water tank is filled with a predetermined amount or more. Thus, it is necessary to continue to replenish water, and the user is required to have continuous water replenishment. Moreover, in the conventional electrostatic atomizer, when the water replenished to the water tank is water containing impurities such as Ca and Mg, such as tap water, these impurities are combined with CO ₂ in the air. The reaction may cause CaCO ₃ , MgO, or the like to deposit and adhere to the tip of the water conveyance unit, thereby preventing the generation of nano ion mist. For this reason, the user is required to perform regular maintenance to remove deposits such as CaCO ₃ and MgO.
Japanese Patent No. 3260150

The present invention has been invented in view of the above-mentioned problems, and does not force the user to replenish water or remove deposits , and even when it is difficult to generate condensed water such as drying. It is an object of the present invention to provide an electrostatic atomizer that can be used.

In order to solve the above-described problems, the present invention can be applied to a water transport unit 11 that transports water by capillary action, a water supply unit 20 that supplies water to the water transport unit, and a voltage with respect to water that the water transport unit 20 transports In an electrostatic atomizer comprising: an application electrode 21 for applying water; and a high voltage application unit 14 for atomizing water at the distal end portion 11a of the water transport unit 11 by applying a high voltage to the application electrode 21. The water supply unit 20 is a heat exchanging unit 4 that has an endothermic surface 8 and cools air on the endothermic surface 8 to generate condensed water D, and stores the condensed water D generated by the heat exchanging unit 4. Te water retention portion 40 supplies the water conveying section 11 provided on the periphery of the absorbing heat surfaces 8, and those features that you have contact and a-holding water 40 and the water conveying section 11. Thus, the water to be supplied to the water transport unit 11 is automatically collected as the condensed water D on the endothermic surface 8, so that the user can perform troublesome water replenishment. The nano ion mist M can be continuously generated by Rayleigh splitting at the front end portions 11a of the plurality of water transport units 11. Moreover, since the dew condensation water D does not contain Ca or Mg like tap water, no adhering matter is generated at the tip end portion 11a of each water transport section 11, and there is no need for troublesome maintenance. In addition, the provision of the water retaining portion 40 at the peripheral edge of the heat absorbing surface 8 allows the condensed water D to be generated in a time zone where a large amount of the condensed water D is generated even in a time zone in which the condensed water D is difficult to occur during the daytime. Nano ion mist M can be continuously generated using dew condensation water D.

The present invention has an effect that it can be used continuously even when it is difficult for condensed water such as drying to occur without forcing the user to replenish water or remove deposits.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. 1 to 3 show a first example of the electrostatic atomizer according to the embodiment of the present invention. A main body case 10 constituting the outer shell of the electrostatic atomizer of this example is formed of a square cylinder-shaped mist generating case 1 and a similarly rectangular cylinder-shaped air blowing case 2 connected in communication therewith. A heat exchange section arrangement port 3 is opened on the connection side of the blower case 2 with the mist generating case 1, and the heat exchange section 4 is fitted to the heat exchange section arrangement port 3. The heat exchanging portion 4 is formed by connecting a heat absorbing plate 6 to the heat absorbing side of the Peltier element 5 which is a semiconductor electronic heat exchanging element and connecting a fin-shaped heat radiating plate 7 to the heat radiating side of the Peltier element 5. The flat outer surface of the heat absorbing plate 6 that comes into contact with the air becomes the heat absorbing surface 8 that generates the condensed water D of the heat exchanging portion 4, and the outer surface of the heat radiating plate 7 that comes into contact with the air is the heat exchanging portion 4. The heat radiation surface 9 is. The heat absorbing plate 6 and the heat radiating plate 7 are formed using a material having high thermal conductivity such as aluminum. Since the Peltier element 5 is vulnerable to water, in order to prevent the dew condensation water D from entering the Peltier element 5, for example, a waterproof heat conduction portion is provided between the heat absorbing plate 6 and the Peltier element 5 as a waterproof heat conduction part. It is preferable to interpose grease (not shown).

  The heat radiating plate 7 of the heat exchanging section 4 is located in the blower case 2, and the heat absorbing plate 6 is located in the mist generating case 1, and the water is conveyed on the heat absorbing surface 8 of the heat absorbing plate 6 in the mist generating case 1. The part 11 is erected. The water conveyance part 11 is a cylindrical member formed using the ceramic which is a porous material, and the front-end | tip part 11a has a sharp cone shape. In addition, the water conveyance part 11 is not limited to the product made from a ceramic, What is necessary is just a porous material which can produce a capillary phenomenon (for example, felt etc.). A ring-shaped counter electrode 13 is positioned at the central portion of the mist discharge port 12 that is opened on the opposite side of the mist generating case 1 to the front end portion 11a of the water transport unit 11. The counter electrode 13 and the heat absorbing plate 6 are connected to a high voltage application unit 14, and the tip 11 a of the water transport unit 11 and the counter electrode 13 are in a state where the water transport unit 11 transports water as will be described later. During this time, a high voltage is applied so that the tip end 11a side of the water transport section 11 becomes a negative electrode.

  A motor fan 15 is disposed in the blower case 2 so as to face the heat radiating plate 7. When the motor fan 15 is driven, an air flow is generated from the blower case 2 side toward the mist generating case 1 side. It is supposed to be. A cylindrical partition wall 16 surrounding the side of the heat radiating plate 7 is extended inward from the opening edge of the heat exchange part arrangement port 3 of the blower case 2, and the internal space surrounded by the partition wall 16 is A discharge duct 22 that communicates with the external space of the blower case 2 penetrates the side peripheral wall 2a of the blower case 2 and protrudes outward. In addition, a predetermined gap 17 is provided between the side peripheral wall 2a of the blower case 2 and the partition wall 16, and the gap 17 has a vent hole 18 formed in the vicinity of the heat exchange part arrangement port 3 of the blower case 2. It communicates with the inside of the mist generating case 1. Reference numeral 19 in the figure denotes a power control unit that is connected to the motor fan 15, the Peltier element 5, and the high voltage application unit 14 and supplies power to each of them.

  Thus, in the electrostatic atomizer described above, when DC power is supplied to the Peltier element 5 of the heat exchanging unit 4 by the power supply control unit 19, heat is generated in the Peltier element 5 and connected to the heat absorption side. The air is cooled on the heat absorbing surface 8 of the heat absorbing plate 6 to generate condensed water D. Since the water conveyance part 11 of this example is provided in the center of the heat absorption surface 8 which comprises substantially square shape, the dew condensation water D produced | generated on this heat absorption surface 8 can carry out water conveyance efficiently by sliding on this heat absorption surface 8. It will be sent to the part 11. Thus, in this example, the heat exchange unit 4 that cools the air on the heat absorption surface 8 to generate the condensed water D is the water supply unit 20 that supplies water to the water transport unit 11. In addition, as an installation location of the water conveyance part 11, it is not limited to the center of the heat absorption surface 8, For example, it is good also as a structure which installed the some water conveyance part 11 in the outer peripheral part of the heat absorption surface 8 at substantially equal intervals. . In this case, even if the heat absorption surface 8 is inclined to some extent in a certain direction, the condensed water D is fed into the water conveyance unit 11 located at least below among the plurality of water conveyance units 11 standing upright. The nano ion mist M can be continuously generated. In order to generate the condensed water D more efficiently and send it to the water transport unit 11, the surface of the endothermic surface 8 is subjected to a hydrophobic treatment, or grooves for guiding water (not shown) are radially formed on the endothermic surface 8. It is preferable to provide a water guide shape for guiding the condensed water D to the water transport unit 11 such as forming.

  The condensed water D sent to the base end part 11b of the water transport part 11 is transported to the front end part 11a by capillary action. In this state, when the water transport unit 11 transports water to the tip end part 11a, when the high voltage application unit 14 applies a high voltage so that the tip end part 11a side of the water transport unit 11 becomes a negative electrode and charges are concentrated, The water held at the tip 11a receives large energy and repeats Rayleigh splitting to generate a large amount of nano ion mist M. The nano ion mist M is discharged to the counter electrode 13 side facing the water transport unit 11 and discharged to the outside of the mist generation case 1. Here, as the tip end portion 11a of the water transport portion 11 is sharply formed, the lines of electric force are formed at a high density, and the discharge efficiency is increased. The distance between the tip 11a of the water transport unit 11 and the counter electrode 13 is set to an appropriate spatial distance so that the electric lines of force are formed at a high density and the nano ion mist M is generated with high efficiency. Keep it. The material of the mist generating case 1 is preferably an insulating material, but if a conductive material similar to the counter electrode 13 or the like is used, it is sufficient between the water transport unit 11 and the mist generating case 1. It is necessary to provide a sufficient air insulation distance.

  In this example, the heat absorbing plate 6 connected to the high voltage application unit 14 serves as an application electrode 21 that applies a voltage to the water conveyed by the water conveyance unit 11, and the application electrode 21 and the counter electrode 13, the high voltage is applied by the high voltage application unit 14, so that charges are concentrated on the tip end portion 11 a of the water transport unit 11. The member to be formed may be provided as a separate member from the heat absorbing plate 6 and connected to the water transport unit 11. The endothermic plate 6, the water transport unit 11, and the counter electrode 13 of this example are conductors each having a resistance value of 3000Ω or less when water is transported to the tip end part 11 a of the water transport unit 11. Is required.

  Furthermore, in the electrostatic atomizer of this example, when the motor fan 15 is driven by the power supply control unit 19, an air flow is generated from the blower case 2 side toward the mist generating case 1 side as described above. Here, the air flow path in the main body case 10 passes through the air gap 18 between the side peripheral wall 2a of the blower case 2 and the partition wall 16 as shown by an arrow in FIG. A mist inducing flow path R1 that is discharged to the outside after flowing into the mist generating case 1, and through the discharge duct 22 after flowing into the partition wall 16 of the blower case 2 as shown by an arrow in FIG. It is branched to a cooling flow path R2 discharged to the outside. The air passing through the mist inducing flow path R1 passes through the vicinity of the heat absorbing surface 8 in the mist generating case 1, and is discharged to the outside along the direction from the water transport unit 11 to the counter electrode 13. At the same time, the nanoion mist M is attracted toward the outside vigorously. Further, the air passing through the cooling flow path R2 passes through the vicinity of the heat radiating plate 7 in the partition wall 16 and is discharged to the outside after taking heat away from the heat radiating surface 9, thereby improving the heat radiating performance of the heat exchanging section 4. It is like that. That is, in this example, the motor fan 15 is a blower unit 23 that sends out air to the heat absorption surface 8 side and the heat dissipation surface 9 side of the heat exchange unit 4, and the air from the blower unit 23 is moved to the heat absorption surface 8 side. Are provided separately with a mist inducing flow path R1 sent out to the heat sink and a cooling flow path R2 sent out to the heat radiation surface 9 side. If the air heated and dried on the side of the heat radiating surface 9 is sent to the side of the heat absorbing surface 8 and cooled, the relative humidity is difficult to rise, so that the dew condensation water D is not easily generated. By making the flow path R1 to the surface 8 side and the flow path R2 to the heat radiating surface side separate, the relative humidity is likely to increase on the heat absorbing surface 8 side, and the condensed water D is likely to be generated.

In the electrostatic atomizer of this example described above, about 20 trillion nano ion mists M are attracted to the air sent out by the motor fan 15 and discharged to the outside for about 20 minutes after discharge. Since it has a property of drifting in the air, various effects such as a high moisturizing effect and deodorizing effect by exposure to the nano ion mist M can be obtained. In addition, it is guessed that the deodorizing effect here is because the radical enclosed in nano ion mist M decompose | disassembles various odor components like following reaction formula, for example.
Ammonia: 2NH ₃ + 6 · OH → N ₂ + 6H ₂ O
Acetaldehyde: CH ₃ CHO + 6 · OH + O ₂ → 2CO ₂ + 5H ₂ O
Acetic acid: CH ₃ COOH + 4 · OH + O ₂ → 2CO ₂ + 4H ₂ O
Methane gas: CH + 4 · OH + O ₂ → CO ₂ + H ₂ O
Carbon monoxide: CO + 2 · OH → CO ₂ + H ₂ O
Nitric oxide: 2NO + 4 · OH → N ₂ + 2CO ₂ + 2H ₂ O
Formaldehyde: HCHO + 4 · OH → CO ₂ + 3H ₂ O
Moreover, the electrostatic atomizer of this example has a structure for collecting water from the air by condensation, and the amount of water required for mist generation can be as little as 0.5 g / h. Therefore, the nano ion mist M can be continuously generated without troublesome water supply. Moreover, since the dew condensation water D does not contain Ca or Mg like tap water, no adhering matter is generated at the tip end portion 11a of the water transport unit 11, and therefore no troublesome maintenance is required. Furthermore, by using a small semiconductor electronic heat exchange element such as the Peltier element 5 as the heat exchange part 4, the entire apparatus can be miniaturized. Thus, the electrostatic atomizer of the present example does not require the effort of water replenishment and removal of deposits in addition to obtaining a high moisturizing effect and deodorizing effect without increasing the indoor humidity, and Since the entire device is also compactly formed, it can be used for humidifiers, esthetic steamers, air purifiers, etc., as well as hand-held electric appliances such as hair dryers and hair quality improvement appliances, indoor lighting appliances, It is also easy to obtain added value by being installed in indoor permanent fixtures such as stand lighting fixtures.

  Next, a second example of the electrostatic atomizer according to the embodiment of the present invention will be described with reference to FIGS. 4 and 5. The basic configuration of this example is the same as the configuration of the first example described above. Therefore, the description of the configuration that matches the first example is omitted, and only the characteristic configuration that is different from the first example is described in detail below. In the electrostatic atomizer of this example, the endothermic surface 8 of the endothermic plate 6 constituting the heat exchanging unit 4 is formed into a concave shape having a bowl-shaped concave portion 30 in which the amount of recesses increases toward the center. The water conveyance part 11 is made to stand in the center part. When the entire apparatus is installed such that the concave heat absorption surface 8 faces upward (the tip portion 11a of the water transport portion 11 faces upward), and the heat absorption surface 8 is cooled by supplying current to the Peltier element 5 The condensed water D generated on the bowl recess 30 of the endothermic surface 8 gradually increases, and when it reaches a certain size, it slides down to the central portion due to its own weight, and reaches the base end portion 11b of the water conveyance portion 11. It will be sent to. Thus, in the electrostatic atomizer of this example, the concave shape of the heat absorbing surface 8 is a water guide shape for guiding the condensed water D to the water transport unit 11 by its own weight, and has this water guide shape. Thus, before the generated condensed water D is reduced due to evaporation or the like, it can be sent to the water transport unit 11 and water can be supplied with high efficiency.

  Next, a third example of the electrostatic atomizer according to the embodiment of the present invention will be described with reference to FIGS. 6 and 7. The basic configuration of this example is the same as the configuration of the second example described above. Therefore, the description of the configuration that matches the second example is omitted, and only the characteristic configuration that is different from the second example is described in detail below. The electrostatic atomizer of the present example includes a water retaining portion 40 formed in a ring shape using a porous material such as felt at the center of the bowl recess 30 of the heat absorbing surface 8. The water retaining part 40 is placed on the heat absorbing surface 8 in a state fitted to the base end part 11b of the water transporting part 11, and can store water for a long time. Yes. Therefore, the dew condensation water D that has slid down on the heat absorption surface 8 toward the center is temporarily stored in the water retention unit 40 and then supplied to the water conveyance unit 11. For example, the water conveyance unit 11 has high temperature and humidity. When the amount of condensed water D generated on the endothermic surface 8 is larger than the amount of water misted at the front end portion 11a, the surplus is stored in the water retaining portion 40, and the temperature and humidity are low and the water transport portion 11 is low. When the amount of condensed water D generated on the endothermic surface 8 is less than the amount of water misted at the tip portion 11a, the water stored in the water retention unit 40 can be supplied to the water transport unit 11. . That is, by providing the water retention part 40 as described above, the nano ion mist M can be continuously generated even in a time zone in which the condensed water D such as dry daytime is difficult to occur.

  Next, the electrostatic atomizer of the fourth example in the embodiment of the present invention will be described with reference to FIG. 8, but the basic configuration of this example is the same as the configuration of the first example described above. The description of the configuration that matches the first example will be omitted, and only the characteristic configuration that is different from the first example will be described in detail below. The electrostatic atomizer of this example is provided with a water retaining part 40 formed in a ring shape using a porous material such as felt on the heat absorbing surface 8 of the heat exchanging part 4. It covers the outer peripheral edge. In addition, the water retaining unit 40 is provided with a plurality of water transport units 11 standing at substantially equal intervals in the circumferential direction. Therefore, in the electrostatic atomizer of the present example, even when the entire apparatus is installed in a posture inclined to a certain direction from the state where the heat absorption surface 8 faces upward, it is generated on the heat absorption surface 8. The condensed water D thus formed is once absorbed by the water retention part 40 provided at the outer peripheral edge of the heat absorbing surface 8. And water spreads the whole inside of the water holding part 40 by capillary action, and water is supplied to all the water conveyance parts 11 via the water holding part 40. Moreover, it is the same as that of the 3rd example that the nano ion mist M can be continuously generated by providing the water retaining part 40 even in a time zone in which the condensed water D is unlikely to be generated during dry daytime or the like. .

  Next, a fifth example of the electrostatic atomizer in the embodiment of the present invention will be described with reference to FIGS. 9 and 10. The basic configuration of this example is the same as the configuration of the fourth example described above. Therefore, the description of the configuration that matches the fourth example is omitted, and only the characteristic configuration that is different from the fourth example is described in detail below. In the electrostatic atomizer of this example, the endothermic surface 8 of the heat exchanging portion 4 is formed into a convex shape having a conical convex portion 50 such that the amount of protrusion increases toward the center, and the outer peripheral edge of the endothermic surface 8 A ring-shaped water retaining part 40 is arranged in the part so as to surround the conical convex part 50, and a plurality of water transport parts 11 are erected on the water retaining part 40 at substantially equal intervals in the circumferential direction. . In the electrostatic atomization device of this example, even when the entire device is installed with a certain degree of inclination in an arbitrary direction from the state where the heat absorbing surface 8 faces upward, Of course, when water is supplied to the water transport unit 11, the condensed water D generated on the heat absorbing surface 8 is conical as shown in FIG. It slides down on the inclined surface of the convex part 50, and is efficiently supplied to the water retention part 40 and the water conveyance part 11. FIG. Thus, in the electrostatic atomizer of this example, the convex surface shape of the heat absorbing surface 8 has a water guide shape for guiding the condensed water D to the water transport unit 11 by its own weight.

  Next, an electrostatic atomizer of a sixth example in the embodiment of the present invention will be described with reference to FIG. 11, but the basic configuration of this example is the same as the configuration of the second example described above. The description of the configuration that matches the second example will be omitted, and only the characteristic configuration that is different from the second example will be described in detail below. In the electrostatic atomizer of this example, a large number of fin-shaped protrusions 60 are formed on the heat-absorbing surface 8 of the heat-absorbing plate 6 constituting the heat exchange unit 4. By providing the projection 60, the area of the heat absorbing surface 8 that comes into contact with air is increased, and a large amount of condensed water D is generated. Therefore, water is efficiently collected from the air. The protrusion 60 is not limited to the fin shape described above, and may be a fine protrusion having a corner at the tip, for example. In this case, in addition to an increase in the area of the endothermic surface 8, there is an advantage that the condensed water D is easily generated because the corner portion of the tip serves as a condensation core. It is needless to say that the same effect can be obtained when the same protrusion 60 as in this example is provided on the heat absorbing surface 8 of the electrostatic atomizer of the first example or the third to fifth examples.

  Next, an electrostatic atomizer of a seventh example in the embodiment of the present invention will be described with reference to FIG. 12, but the basic configuration of this example is the same as the configuration of the second example described above. The description of the configuration that matches the second example will be omitted, and only the characteristic configuration that is different from the second example will be described in detail below. The electrostatic atomizer of this example includes a vibration generating unit 70 using a motor 71 on the outer peripheral surface of the discharge duct 22 protruding sideways from the blower case 2. The vibration generating unit 70 is a vibration motor in which a weight part 72 is attached to a motor shaft 71a protruding from the motor 71, and the motor 72 is appropriately displaced from the center of gravity of the weight part 72 and the axis of the motor shaft 71a. When 71 is driven, vibration is generated by the rotation of the weight portion 72. When vibration is generated by the vibration generating unit 70 arranged in the main body case 10 as described above, the heat absorbing surface 8 of the heat exchange unit 4 arranged in the main body case 10 vibrates and is generated on the heat absorbing surface 8. The fine dew condensation water D is combined by vibration to form large water droplets, so that it slides down toward the water transport unit 11 at an early stage. In other words, the electrostatic atomizer of this example is provided with the vibration generator 70 to accelerate the collection of the condensed water D so that the nano ion mist M is generated quickly after the apparatus is started. Needless to say, the same effect can be obtained when the vibration generating unit 70 similar to the present example is provided in the electrostatic atomizer of the first example or the third to sixth examples.

  Next, an electrostatic atomizer of an eighth example according to the embodiment of the present invention will be described with reference to FIG. 13, but the basic configuration of this example is the same as the configuration of the first example described above. The description of the configuration that matches the first example will be omitted, and only the characteristic configuration that is different from the first example will be described in detail below. The electrostatic atomizer of this example includes a motor fan 15 on the side of the heat exchanging unit 4 as the air blowing unit 23, and also serves as a flow path for air sent from the motor fan 15 to the water transport unit 11. Mist inducing flow path R1 that is discharged to the outside after being sent to the portion where the nano ion mist M is generated between the counter electrode 13 and the counter electrode 13, and is directly sent from the motor fan 15 to the heat radiation surface 9 side and then discharged to the outside. A cooling flow path R2 and a second cooling flow path R3 which is sent from the motor fan 15 to the heat absorption surface 8 side and then sent to the heat radiation surface 9 side and discharged to the outside are separately provided. Therefore, in the electrostatic atomizer of this example, the driving of the motor fan 15 causes the nano ion mist M to be ejected to the outside with the air passing through the mist inducing channel R1, and the air passing through the cooling channel R2. In addition to depriving the heat radiation surface 9 by heat, the heat on the heat radiation surface 9 side can be deprived using the air cooled on the heat absorption surface 8 side through the second cooling channel R3. Thus, by adopting a structure in which heat is removed from the heat dissipation surface 9 even by air moving from the heat absorption surface 8 side to the heat dissipation surface 9 side, heat absorption and heat dissipation at the heat exchanging portion 4 are efficiently performed. It is needless to say that the same effect can be obtained when the same flow path as in this example is provided in the electrostatic atomizers of the second to seventh examples.

  In addition, although the electrostatic atomizer of the above-described first to eighth examples has a structure in which the heat absorption plate 6 of the heat exchange unit 4 and the water conveyance unit 11 are provided separately, the present invention is not limited thereto, and the heat absorption unit You may integrally form the board 6 and the water conveyance part 11 using the porous material which can produce capillary phenomena, such as a ceramic. In this case, the condensed water D generated on the endothermic surface 8 of the endothermic plate 6 is absorbed as it is into the endothermic plate 6, and capillarity is caused to the water conveyance unit 11 formed integrally with the endothermic plate 6. It will be sent efficiently. A material such as ceramic is a material having high water absorption but low thermal conductivity, but it can be used as a material for the heat absorbing plate 6 because the surface temperature can be easily lowered by forming a thin film. It is.
