Description

  The present invention relates to an electrostatic atomizer that generates nanometer-sized charged fine particle water by an electrostatic atomization phenomenon and supplies it to a space to be atomized.

  Conventionally, an atomizing electrode, a counter electrode positioned opposite to the atomizing electrode, and a supply means for supplying water to the atomizing electrode are provided, and a high voltage is applied between the atomizing electrode and the counter electrode. Patent Document 1 discloses an electrostatic atomizer that atomizes water held by an atomizing electrode and generates charged fine particle water (charged ion mist of nanometer size) having a strong charge at the nanometer size.

  This nano-sized meter's charged fine particle water has a moisturizing effect, and also has a deodorizing effect because of the presence of the active species in the form of water molecules. Nanometer-sized charged fine particle water that exists in such a way that the active species is encapsulated in water molecules has a longer life than when free radicals exist alone, and is very small at nanometer size, so it floats in the air for a long time. At the same time, it has a high diffusibility and floats uniformly in the air for a long period of time, thereby enhancing the deodorizing effect.

However, in the conventional electrostatic atomizer shown in Patent Document 1, the water supply means includes a water tank filled with water, and water that transports water in the water tank to the atomization electrode by capillary action. Since the structure is equipped with a transport unit, the user needs to replenish water in the water tank continuously, which is troublesome and troublesome to replenish water. It was. Further, in the above electrostatic atomizer, when the water to be supplied is water containing impurities such as Ca and Mg such as tap water, the impurities react with CO ₂ in the air and the water transport unit CaCO ₃ , MgO, or the like is deposited on the tip of the glass, obstructing the supply of water by capillary action, and preventing the generation of nanometer-sized charged fine particle water.

  Therefore, in order to solve the above problem, the atomizing electrode is connected to the cooling part of the Peltier unit to cool the atomizing electrode, and the atomizing electrode is cooled to condense moisture in the air. Patent Document 2 discloses that water is supplied and a high voltage is applied between the atomizing electrode and the counter electrode to electrostatically atomize water (condensation water) supplied to the atomizing electrode. ing.

The conventional example of Patent Document 2 has a feature that the labor of replenishing water is not required, and the obtained water does not contain impurities, so that CaCO ₃ , MgO, and the like do not deposit.

  However, in the conventional example shown in Patent Document 2 above, a Peltier unit and a control circuit for the Peltier unit are necessary, and waterproofing measures are necessary so that condensed water does not enter the Peltier unit side. For these reasons, there is a problem that the cost is increased and the size is increased because the Peltier unit is provided.

  Hereinafter, although the refrigerator A1 is demonstrated as an example as the apparatus A provided with the atomization object space 1 and the cold space 4 as an example, this invention is not necessarily limited to a refrigerator.

  FIG. 5 shows a schematic configuration diagram of the refrigerator A1. In FIG. 5, reference numeral 20 denotes a refrigerator main body, which includes a freezer compartment 21, a vegetable compartment 22, a refrigeration compartment 23, and a cold air passage 24. Moreover, the partition part 6 which partitions off the refrigerator compartment 23 and the cold air | gas channel | path 24 is comprised with the heat insulating material. An outer skin 6a made of a synthetic resin molded product is laminated and integrated on the surface of the heat insulating material of the partition portion 6. The cool air passage 24 and the freezer compartment 21, the cold air passage 24 and the vegetable compartment 22, and the cold air passage 24 and the refrigerating compartment 23 communicate with the partition sections 6 that partition the cold air passage 24 and the freezer compartment 21, the vegetable compartment 22, and the refrigerator compartment 23, respectively.

Here, since the temperature of the vegetable compartment 22 and the refrigerator compartment 23 is higher than that of the freezer compartment 21 (for example, the vegetable compartment 22 is about 5 ° C.), the communication portions 27b and 27c are smaller openings than the communication passage 27a. The inflow amount of cold air from the cold air passage 24 is set to be smaller than that in the freezer compartment 21.

It is located on the same axis as the center of the central hole of the electrode 3. The atomization electrode 2 and the counter electrode 3 are electrically connected to the high voltage application unit 9 through a high-voltage lead wire.

  At the rear end of the atomizing electrode 2, a heat transfer part 5 having good thermal conductivity such as metal is provided. Here, the atomization electrode 2 and the heat transfer part 5 may be integrally formed, the separate heat transfer part 5 may be fixed to the atomization electrode 2, and the atomization electrode 2 may be fixed to the atomization electrode 2. A separate heat transfer section 5 may be brought into contact with the heat transfer section 5. In either case, the heat transfer unit 5 and the atomizing electrode 2 are configured to exchange heat efficiently.

In the embodiment shown in FIGS. 1 and 2, a recess 5a is formed in the front surface portion of the columnar metal heat transfer section 5, and a fitting hole 5b is formed in the bottom of the recess 5a. the distal end portion of the write Mutotomoni atomizing electrode 2 fitted to the rear end of the atomizing electrode 2 in which the rod-shaped are protruded forward from the front surface of the heat transfer portion 5. Therefore, in this embodiment, the atomization electrode 2 and the heat transfer part 5 are in addition to the heat exchange by heat conduction caused by the contact between the inner surface of the fitting hole 5b and the rear end part of the atomization electrode 2, and the recess 5a Heat can be effectively exchanged by exchanging heat between the inner surface and the atomizing electrode 2 facing the inner surface.

  Moreover, in embodiment shown in FIG. 3, the atomization electrode 2 and the heat-transfer part 5 were integrally formed, and the rear-end part of the atomization electrode 2 is the heat-transfer part 5. FIG.

  The heat transfer section 5 is attached to the apparatus housing 11 (in the embodiment shown in FIGS. 1 and 2, in the embodiment shown in FIG. 3, the heat transfer section 5 is attached to the lid portion 11 c constituting a part of the rear surface section of the apparatus housing 11. Installed). A hole 12 is provided on the rear surface of the device housing 11 (in the embodiment shown in FIGS. 1 and 2, in the embodiment shown in FIG. 3, the hole 12 is provided in the lid 11 c), and the heat transfer part 5 is provided. It faces this hole 12. In this case, the rear end surface portion of the heat transfer section 5 may not protrude rearward from the hole 12, and the heat transfer section as in the embodiment shown in FIGS. 1 and 2 and the embodiment shown in FIG. 5 may protrude from the hole 12.

  Part 7 of the partition part 6 is provided with a part 7 where heat is more easily transmitted than the other part of the partition part 6. In providing the part 7 in which heat is easy to be transmitted, for example, the thickness of a part of the partition part 6 made of a heat insulating material is thinned to form the part 7 in which heat is easily transmitted, A part 7 is made of a material that conducts heat more easily than other parts of the partition part 6, so that a part 7 that easily conducts heat is formed, or a part of the partition part 6 made of heat insulating material is atomized. A portion 7 in which heat is easily transmitted is formed by opening a communication hole that connects the target space 1 and the cold space 4.

  In configuring the portion 7 in which a part of the partition part 6 is thinned and heat is easily transmitted, a part of the partition part 6 can be easily thinned by forming the concave portion 8. The recessed part 8 is formed in the atomization object space 1 side of the partition part 6, the recessed part 8 is formed in the cold space 4 side, or the recessed part 8 is formed in both the atomization object space 1 side and the cold space 4 side. can do. In addition, the part corresponding to the circumference | surroundings of the part 7 in which the heat | fever of the outer skin 6a is easy to transmit is perforated, and a heat insulating material is exposed to the atomization object space 1 side.

  In attaching the apparatus housing 11 to the surface of the partitioning portion 6 on the atomization target space 1 side, the heat transfer portion 5 is in contact with or smaller than the portion 7 where heat is more easily transferred than the other portions provided in the partitioning portion 6. Install so as to face each other through a gap.

  Thus, the heat transfer part 5 is provided in the part 7 in which the heat provided in the partition part 6 is easily transmitted, and the heat transfer part 5 is cooled by the exchange of heat with the cold space 4, so that the atomizing electrode 2 is made conventional. Thus, without using a Peltier unit, it is possible to cool the atomizing electrode 2 to generate condensed water, supply water, and electrostatic atomize to supply nanometer-sized charged fine particle water to the atomization target space 1.

  Moreover, when the recessed part 8 is provided in the atomization object space 1 side of the partition part 6 and the part 7 which heat is easy to transmit is comprised, it is the simple structure of forming the recessed part 8 in a part of partition part 6 which consists of heat insulating materials. A part 7 in which heat is more easily transmitted than in other parts can be formed in a part of the partition 6, and the heat transfer part 5 is inserted into the recess 8, so that heat is transmitted through the part 7 in which heat is easily transmitted. The heat exchange between the heat section 5 and the cold space 4 can be efficiently performed, and the heat transfer section 5 portion, which is a part of the electrostatic atomizer, is inserted into the recess 8 so that the electrostatic fog The atomization device can be positioned when attached to the atomization target space 1, and the protrusion length of the electrostatic atomization device into the atomization target space 1 can be shortened at least for the insertion length. 1 can be used widely.

Further, the hole 12 provided on the rear surface of the housing 11 is faced to the heat transfer portion 5, the heat transfer unit 5 as well as disposed me along the partition 6 in the mist-space 1 a housing 11 partition By facing the portion 7 where the heat of the portion 6 is easily transmitted, the heat transfer portion 5 can be effectively cooled by the exchange of heat with the cold space 4 without being affected by the device housing 11. By disposing the electrode 3, the high voltage application unit 9, and the control unit 10 in the apparatus housing 11, the counter electrode 3, the high voltage application unit 9, and the control unit 10 are unnecessarily cooled by exchanging heat with the cold space 4. It is possible to prevent the formation of condensed water on these parts, and to prevent the adverse effects caused by the condensed water adhering to these parts.

  Here, as in the embodiment shown in FIGS. 1 and 2 and the embodiment shown in FIG. 3, by inserting the protruding portion 5 c protruding from the hole portion 12 of the heat transfer portion 5 into the recessed portion 8, Heat exchange between the heat transfer section 5 and the cold space 4 can be performed more effectively.

  In addition, by adopting a configuration in which the protruding portion 5 c is inserted into the recessed portion 8, positioning can be performed when the device housing 11 is attached to the atomization target space 1 side of the partition portion 6, and the heat transfer portion 5 can be accurately positioned in the partition portion 6. It can be made to oppose the part 7 which heat | fever transmits easily.

  When the protrusion 5c of the heat transfer section 5 is configured to be in close contact with the recess 8, heat exchange between the heat transfer section 5 and the cold space 4 can be performed more effectively.

  On the other hand, if the inner diameter of the recess 8 is set to be slightly larger than the diameter of the protrusion 5c, manufacturing errors of the recess 8 and the protrusion 5c, errors in the mounting position of the apparatus housing 11 on the partition 6 and the like may occur. This can be absorbed and the protrusion 5c can be inserted into the recess 8.

  As described above, the heat transfer part 5 of the atomizing electrode 2 is positioned so as to face the part 7 where heat is easily transmitted provided in a part of the partition part 6, so that the atomization is performed by the partition part 6 made of a heat insulating material. Although the target space 1 and the cold space 4 are insulated, only the heat transfer section 5 is a member constituting the main part B of the electrostatic atomizer installed in the atomization target space 1, The temperature of the atomization electrode 2 is lowered to a temperature lower than that of the portion, and moisture contained in the air in the discharge chamber 11b is generated in the atomization electrode 2 as condensed water. In this way, water is stably supplied to the atomizing electrode 2.

  When a high voltage is applied between the atomization electrode 2 and the counter electrode 3 by the high voltage application unit 9 in a state where water is supplied to the atomization electrode 2 in this way, the atomization electrode 2, the counter electrode 3, The coulomb force works between the water supplied to the tip of the atomizing electrode 2 and the counter electrode 3 due to the high voltage applied between the two, and the water level rises locally in a cone shape (tailor cone) Is formed. When the tailor cone is formed in this way, the electric charge concentrates on the tip of the tailor cone and the electric field strength in this portion increases, thereby increasing the Coulomb force generated in this portion and further growing the tailor cone. . When the tailor cone grows like this and the charge concentrates on the tip of the tailor cone and the density of the charge becomes high, the water at the tip of the tailor cone has a large energy (repulsive force of the charge that has become dense). In response, the surface tension is exceeded, and splitting and scattering (Rayleigh splitting) are repeated to generate a large amount of nanometer-sized charged fine particle water.

  The nanometer-sized charged fine particle water thus generated passes through the central hole of the counter electrode 3 and is discharged into the atomization target space 1 from the discharge opening 14 provided on the front surface of the apparatus housing 11. Since the nanometer-sized charged fine particle water discharged into the atomization target space 1 is extremely small as nanometer size, it floats in the air for a long time and has high diffusivity. Deodorized because it adheres to the inner surface of the atomization target space 1 and the stored items stored in the atomization target space 1 and the nanometer-sized charged fine particle water active species are encased in water molecules. It has the effect of suppressing the sterilization and propagation of molds and fungi, and adheres to the inner surface of the atomization target space 1 and the stored items in the atomization target space 1 to deodorize the fungi and fungi. The effect of suppressing breeding will be demonstrated. In addition, nanometer-sized charged fine particle water that exists in such a way that active species are encapsulated in water molecules has a longer life than the case where free radicals exist alone, so the above diffusibility, deodorizing effect, fungi and fungi sterilization and propagation This will further improve the suppression effect. In addition, since the nanometer-size charged fine particle water has a moisturizing effect, it has an effect of moisturizing the stored items in the atomization target space 1.

  Next, another embodiment of the present invention will be described with reference to FIG.

  As described above, the air around the atomization electrode 2 is cooled by cooling the atomization electrode 2 by cooling the heat transfer portion 5 by heat exchange between the heat transfer portion 5 provided in the atomization electrode 2 and the cold space 4. When the moisture of the inside is condensed to generate condensed water on the atomizing electrode 2 and the water is supplied, the temperature of the cold space 4 varies or the temperature and humidity in the atomization target space 1 vary. There is a possibility that it is difficult to effectively generate an appropriate amount of moisture in the air around the atomizing electrode 2 as condensed water on the atomizing electrode 2. Therefore, in the present embodiment, the temperature adjusting means 13 for adjusting the temperature of the heat transfer section 5 that is cooled by exchanging heat with the cold space 4 is provided.

  In the embodiment shown in FIG. 4, temperature adjusting means 13 is provided next to or around the heat transfer section 5. A temperature sensor 30 for detecting the temperature of the atomization target space 1 and a humidity sensor 31 for detecting the humidity of the atomization target space 1 are provided on the atomization target space 1 side. However, it may be provided in the discharge chamber 11b. A temperature sensor 32 that detects the temperature of the cold space 4 is provided on the cold space 4 side. The temperature information in the atomization target space 1 by the temperature sensor 30 and the humidity sensor 31, the humidity information, and the temperature information in the cold space 4 by the temperature sensor 32 are sent to the control unit 10, and the heat transfer unit 5 and the cold space 4 When the atomization electrode 2 is cooled to a temperature of 0 ° C. by the exchange of heat, the water in the air around the atomization electrode 2 (that is, the air in the atomization target space 1) is water necessary for electrostatic atomization. Of the heat transfer section 5 that is cooled by heat exchange with the cold space 4 by the temperature adjusting means 13 so that the atomization electrode 2 can reach a target temperature. Control is performed by the control unit 10 so as to adjust the temperature.

  For example, the temperature adjusting means 13 includes a heater, and the temperature in the cold space 4 is lowered as in the case of switching to the quick freezing mode in the refrigerator A1, or the temperature in the atomization target space 1 is increased by opening the door 25c. If the temperature in the atomization target space 1 rises due to the temperature of the stored item or the humidity increases at the initial stage of storing the stored item in the atomized target space 1, The heat transfer section 5 is cooled more than necessary due to heat exchange with the space 4, and the atomization electrode 2 is cooled further than the temperature necessary for generating an appropriate amount of condensed water. It freezes. Therefore, when the temperature of the cold space 4 fluctuates or the temperature and humidity in the atomization target space 1 fluctuate in this way, the temperature of the heat transfer section 5 cooled by heat exchange with the cold space 4 is adjusted. It is possible to adjust the temperature by adjusting the temperature by heating with the heater which is means 13, and the atomizing electrode 2 can be adjusted to a temperature at which ambient air can be generated as condensed water in an optimal state. Therefore, water can be stably supplied to the atomizing electrode 2, and electrostatic atomization can be stably performed.

  In the above embodiment, the humidity sensor 31 is described as an example. However, the temperature sensor 30 for detecting the temperature of the atomization target space 1 and the temperature sensor 32 for detecting the temperature of the cold space 4 are provided. It may be.

  In any of the above embodiments, when the high voltage is applied between the atomizing electrode 2 and the counter electrode 3 to electrostatically atomize the water supplied to the atomizing electrode 2, for example, the counter electrode 3 side is atomized. By applying a voltage between the atomizing electrode 2 and the counter electrode 3 so that the potential is higher by about 5 kV than the electrode 2 side, water supplied to the tip of the atomizing electrode 2 can be effectively electrostatically charged. It can be atomized to produce nanometer-sized charged fine particle water.

  In this case, the absolute voltage value on the atomizing electrode 2 side may be larger than the absolute voltage value on the counter electrode 3 side (that is, the potential on the counter electrode 3 side is set to the ground potential (0 V) or The potential on the electrode 3 side may be closer to the ground potential (0 V) than the potential on the atomizing electrode 2 side), but the absolute voltage value on the counter electrode 3 side is the absolute voltage on the atomizing electrode 2 side. (That is, the potential on the atomizing electrode 2 side is set to the ground potential (0V) or the potential on the atomizing electrode 2 side is set to the ground potential (0V) than the potential on the counter electrode 3 side. ).

  The potential on the atomizing electrode 2 side is set to the ground potential (0 V), or the potential on the atomizing electrode 2 side is set to a potential closer to the ground potential (0 V) than the potential on the counter electrode 3 side. A case where a voltage is applied so as to have a predetermined potential difference (for example, 5 kV) between them will be further described.

  For example, the counter electrode 3 is set so that the potential on the atomizing electrode 2 side is set to the ground potential (0 V) or the potential on the atomizing electrode 2 side is set to a potential closer to the ground potential (0 V) than the potential on the counter electrode 3 side. And a voltage is applied between the atomizing electrode 2 and the counter electrode 3 so that negative ions I are generated on the atomizing electrode 2 side (for example, 5 kV). 6, when the counter electrode 3 side is +5 kV and the atomization electrode 2 side is 0 V), the counter electrode 3 side is the positive electrode side, and thus the generation occurs on the atomization electrode 2 side. Most of the negative ions I adhere to the counter electrode 3, which is a positive electrode, and the negative ions I generated during electrostatic atomization are stored in the inner surface of the atomization target space 1 or the stored item C stored in the atomization target space 1. Atomization target space 1 inner surface or fog without sticking in large quantities The stored item C stored in the target space 1 is less likely to be charged, and even if the stored item C stored in the atomization target space 1 or the atomized target space 1 is touched by hand, there is no discomfort due to charging. .

  Although illustration is omitted, when a voltage is applied between the atomizing electrode 2 and the counter electrode 3 so that positive ions are generated on the atomizing electrode 2 side, the counter electrode 3 side is set to the negative electrode side. Therefore, most of the positive ions generated on the atomizing electrode 2 side adhere to the counter electrode 3 which is a negative pole, and the stored items are stored in the inner surface of the atomization target space 1 or in the atomization target space 1. The container stored in the atomization target space 1 or the atomization target space 1 is not easily charged, and the storage stored in the atomization target space 1 or the atomization target space 1 is difficult to be charged. Even if you touch an object with your hand, you can avoid discomfort caused by charging.

  On the other hand, in any of the above cases, the charged fine particle water M that is negatively or positively charged is extremely small in nanometer size, but has a much larger mass than the negative ion I (or positive ion). When the moving force is given by the above, while being released into the atomization target space 1 due to inertia and floating, the container C placed in the atomization target space 1 or the inner surface of the atomization target space 1 is attached, Effective sterilization, antibacterial, deodorant, moisturizing, etc.

  As described above, in the present embodiment, the amount of negative ions (or positive ions) attached to the inner surface of the storage object C or the atomization target space 1 placed in the atomization target space 1 is reduced. Since troubles and electric shocks due to charging of charged objects such as the stored item C and the inner surface of the atomization target space 1 can be avoided, the atomization target space 1 is particularly limited to a small closed space where charging is a problem (for example, a refrigerator). This is suitable when discharging charged fine particle water M generated by electrostatic atomization into a vegetable room or a refrigerator room (A1).

  Here, in the above example, the voltage is applied so that the atomizing electrode 2 is 0 V and the counter electrode 3 is +5 kV. However, in order to electrostatically atomize the water supplied to the atomizing electrode 2, When applying a voltage so that the atomizing electrode 2 and the counter electrode 3 have a predetermined potential difference, the potential on the atomizing electrode 2 side is set to the ground potential (0 V) or the potential on the atomizing electrode 2 side is opposed to The present invention is not limited to the above example as long as a voltage is applied between the atomizing electrode 2 and the counter electrode 3 so as to be closer to the ground potential (0 V) than the potential on the electrode 3 side. Preferably, the voltage value to be applied to the atomizing electrode 2 on the lower absolute voltage value side is set within ± 1 kV, and the voltage is applied so that the counter electrode 3 side has a higher absolute voltage value than the atomizing electrode 2 side. Therefore, in addition to the above-described charge reduction effect, an effect of preventing electric shock from charged objects can be achieved, which is more preferable.
