  The present invention relates to an air conditioner equipped with an electrostatic atomizer that generates nanometer-size mist (particulate water) by an electrostatic atomization phenomenon.

  Conventionally, electrostatic energy that collects moisture in the air on the surface of a metal bar using a Peltier element and crushes the water into the air by applying a high voltage to the metal bar. An air conditioner equipped with an atomizing device has been proposed (see Patent Document 1).

Mist produced by crushing water with a high voltage has a particle size of about 3 to 50 nm (nanometer = ^10-9 meters) and is smaller than the size of the horny cells of the human body. It provides a moisturizing effect. Further, since the mist is charged by a high voltage, it is easy to approach a person who generates a potential difference, and an effect can be obtained even in a large room.

  However, the air conditioner having the conventional electrostatic atomizer described in Patent Document 1 discloses a configuration in which the electrostatic atomizer is installed in the vicinity of the suction port on the upstream side of the heat exchanger. However, the specific configuration of the Peltier unit, discharge electrode, etc. is not described.

  Hereinafter, the subject in the case of installing an electrostatic atomizer in the downstream of the suction opening of an air conditioner and the upstream of a heat exchanger is demonstrated. The case where the electrostatic atomizer is provided with a counter electrode which is a ground electrode and the case where the electrostatic atomizer is not provided with a counter electrode which is a ground electrode will be described separately.

First, the subject in the case of installing an electrostatic atomizer provided with the counter electrode which is a ground electrode in the downstream of the suction opening of an air conditioner and the upstream of a heat exchanger is demonstrated.
(1) Since the heat exchanger is grounded, when the electrostatic atomizer is close to the heat exchanger, there is a problem that generation of mist is not stable due to the influence of the heat exchanger.
(2) If the discharge electrode or grounding electrode of the electrostatic atomizer and the heat exchanger come in contact with or close to each other due to an assembly error during the manufacture of the indoor unit of the air conditioner, the electrostatic atomizer from the air There was a problem that unnecessary discharge toward the heat exchanger was caused, noise and noise were generated, and generation of mist was hindered.
(3) If the heat exchanger and the fins provided in the Peltier unit come into contact with each other due to assembly errors during the manufacture of the indoor unit of the air conditioner, the desired heat absorption performance (cooling) is affected by the heat effect during heating. Performance) is not obtained, and the voltage of the commercial power supply (100V) is not normal (for example, a state where the electric potential of the heat exchanger becomes the voltage level of the commercial power supply due to a failure (short circuit etc.) of the electric circuit of the indoor unit). Or 200V) flows into the Peltier unit and there is a problem that the Peltier unit may be damaged.

Next, a problem in the case where an electrostatic atomizer that does not include a counter electrode that is a ground electrode is installed on the downstream side of the air inlet of the air conditioner and upstream of the heat exchanger will be described.
(1) When a mist is emitted toward the air without providing a special electric field, the opposing heat exchanger is grounded, so that when the heat exchanger is close to the electrostatic atomizer, heat is generated. There was a problem that the generation of mist was not stable under the influence of the exchanger.
(2) When a heat exchanger is used as a ground electrode without providing a special counter electrode, the distance between the heat exchanger and the water application electrode of the electrostatic atomizer (distance between the electrodes) is an assembly error. When it fluctuates according to, there was a problem that generation of mist was not stable.
(3) When the heat exchanger or the cooling unit provided in the Peltier unit comes into contact with each other due to an assembly error during manufacture, when an abnormality occurs (for example, due to a failure (short circuit etc.) in the electric circuit of the indoor unit, There is a problem that the voltage of the commercial power supply (100V or 200V) flows into the Peltier unit in a state where the potential of the heat exchanger becomes the level of the commercial power supply, and the Peltier unit may be damaged. .
(4) If the heat exchanger and the heat sink provided in the Peltier unit come into contact with each other due to an assembly error during production, the heat effect from the heat exchanger is directly received during heating operation, and heat cannot be dissipated. There was a problem that the Peltier unit did not work properly, the cooling part could not be cooled, and condensed water could not be obtained.

  As described above, an electrostatic atomizer to which a high voltage is applied (an electrostatic atomizer that includes a counter electrode that is a ground electrode or an electrostatic atomizer that does not include a counter electrode that is a ground electrode) When the heat exchanger is provided on the downstream side of the inlet of the conditioner and on the upstream side of the heat exchanger, it is necessary to prevent the heat exchanger from approaching the water application electrode beyond a certain distance.

Embodiment 1 FIG.
1 and 2 are diagrams showing Embodiment 1, FIG. 1 is a schematic configuration diagram of an electrostatic atomizer 100, and FIG. 2 is a side view of the electrostatic atomizer 100. FIG. First, the structure of the electrostatic atomizer 100 is demonstrated, referring FIG. 1, FIG.

As shown in FIGS. 1 and 2, the electrostatic atomization apparatus 100 according to the present embodiment generates a nanometer (10 ⁻⁹ m) size electrostatic mist 1, which is a water application electrode 2 that is a discharge electrode. And a counter electrode 3 that is a ground electrode.

  The water application electrode 2 is composed of a plate-shaped body portion 28 and a tip atomizing portion 29, and moves (conveys) the water supplied to the body portion 28 to the tip atomizing portion 29. The tip 29 a (protruding tip) of the tip atomizing portion 29 is arranged so as to face the counter electrode 3. The water application electrode 2 is made of a porous material.

  A high voltage of about 4 to 6 kV supplied from the high voltage power supply unit 4 is applied between the water application electrode 2 and the counter electrode 3 via a power supply terminal 25 (for example, see FIG. 6). Here, the counter electrode 3 serves as a ground electrode (also referred to as a ground electrode) and has a potential of 0 V, and a negative DC voltage of −4 to −6 kV is applied to the water application electrode 2. In order to maintain a constant amount of mist, it is preferable to perform constant current control by varying the voltage.

  The shape of the body portion 28 of the water application electrode 2 is substantially rectangular, and a space of a predetermined distance L10 is provided above the body portion 28 to contact the cooling surface of the Peltier unit 6 that is a part of the water supply unit. The plurality of cooling fins 8b of the cooling unit 8 are positioned in a state where they are arranged in parallel at a predetermined interval in a substantially horizontal direction. The body portion 28 is formed by extending the width in the long side direction (width in the longitudinal direction) in the direction in which the cooling fins 8b are arranged in parallel. That is, the long side direction (longitudinal direction) of the substantially rectangular trunk portion 28 substantially coincides with the stacking direction of the cooling fins 8 b of the cooling portion 8.

  The water application electrode 2 is provided with a plate-shaped body portion 28 that is positioned below the cooling fin 8b with a gap of a predetermined distance L10 and extends in the longitudinal direction (long side direction) in the direction in which the cooling fins 8b are arranged in parallel. Have. And the short side direction of the trunk | drum 28 is substantially corresponded to the direction from which the cooling fin 8b protrudes. The body portion 28 has an elongated shape having a width in the long side direction that is at least three times the width in the short side direction. The plate-like water application electrode 2 has a plate thickness smaller than the width in the short side direction of the body portion 28. In addition, although the shape of the trunk | drum 28 is demonstrated as a substantially rectangular shape, it is not limited to the perfect rectangle whose angle between a long side and a short side is a right angle, A parallelogram and a trapezoid are also included. is there.

  Further, as shown in FIG. 1, the water application electrode 2 has a tip atomizing portion 29 that protrudes from the side surface of one long side of the body portion 28 (in the direction in which the cooling fin 8b protrudes). Is formed. The tip atomizing portion 29 is a plate-like protrusion having the same thickness and continuing from the body portion 28, and its shape is triangular when viewed from above. In the triangular tip atomizing portion 29, the bottom surface is connected to one long side surface of the body portion 28, and the tip 29 a (protruding tip) that is the apex faces the counter electrode 3. The tip 29a becomes a discharge portion for the counter electrode 3.

  Moreover, the shape of the trunk | drum 28 is not limited to a substantially rectangular shape, A cylinder with a circular cross section may be sufficient. In this case, the water application electrode may have a shape like a pencil in use in which a conical tip atomizing portion with a sharp tip is connected to the tip of a cylindrical body. The tip atomizing portion may be an acute angle so that an electric field is likely to gather, or may be a curved surface portion so as to easily form a tailor cone. The tailor cone will be described later.

  1 and 2 show the case where the tip atomizing portion 29 has one protrusion, but there may be a plurality of protrusions, or a plurality of approximately 10 to 10 substantially pencil-shaped water application electrodes. You can make it easier to receive water by arranging them side by side. In that case, if an electric field is uniformly applied to each water application electrode, the amount of mist atomization also increases.

  The material of the water application electrode 2 has a sufficient electrical absorption performance and transport performance, and has a low electrical resistivity (volume resistivity) and high electrical conductivity, and efficiently transmits electricity to the atomized water for charging. It is desirable that the material be able to be made. A more specific example is a foam metal that is a porous metal such as titanium, stainless steel, or nickel. In this embodiment, the water application electrode 2 is formed of a foam metal made of titanium.

  FIG. 3 is a diagram showing the first embodiment, and is an enlarged conceptual diagram for explaining the foam metal used for the water application electrode 2.

  Since FIG. 3 shows a plane (two-dimensional) shape, each pore appears to be independent. However, an actual foam metal is a continuous pore structure in which pores are three-dimensionally continuous. is there. As shown in FIG. 3, the foam metal used as the water application electrode 2 in the electrostatic atomizer of the present embodiment is composed of a baked and solidified metal portion 22 and pores 21 that become void portions. Here, the diameter of the pores 21 is defined as the hole diameter. The size of the hole diameter can be determined from an image taken with an electron microscope. It is also possible to measure not only the pore diameter but also the pore distribution using a mercury intrusion porosimeter or a gas adsorption measuring device.

  The pore diameter of the foam metal of the water application electrode 2 is 10 to 1000 μm, but the foam metal with a pore diameter of 50 to 600 μm is suitable from the viewpoint of water absorption and clogging, and further has rigidity and productivity (workability). ) Is optimally 150 to 300 μm.

  When the pore diameter is less than 10 μm like ceramic, the pore diameter becomes too fine (too small) and there is a high risk of clogging, and the amount of water absorption is also small. In addition, it is difficult to stably arrange the pores 21 in a small size in the production of foam metal. On the other hand, when the pore diameter exceeds 1000 μm, the water absorbed through the continuous pores 21 is likely to leak, making it difficult to transport the water from the body portion 28 to the tip atomizing portion 29.

  In addition, ceramics such as titania, mullite, silica, and alumina having a porosity of about 20 to 50% and a pore diameter of about several to several tens of μm can be used as a porous material that serves as both water transport and discharge. Ceramics have the advantages of being able to transport water by capillarity, having good workability and excellent wear resistance from high voltages, but it is necessary to pay attention to clogging. Further, as the organic material, a water-absorbing material such as PE (polyethylene) used in an ink pen or the like can be used. In addition, a conductive material may be mixed with an organic material, and the water application electrode having various shapes such as a circle can be obtained at a lower cost than a metal material.

  The counter electrode 3 is formed into a plate shape with a resin having a low resistance mixed with a conductive metal or a conductive polymer or filler, and has an opening 3a at substantially the center. The counter electrode 3 is located at a certain distance from the tip 29a of the tip atomizing portion 29 so that the opening 3a faces the tip atomizing portion 29 of the water application electrode 2. The electric field strength is determined by this distance.

  Next, the water supply part located above the water application electrode 2 will be described. The electrostatic atomizer 100 shown in FIGS. 1 and 2 includes a Peltier unit 6, a heat radiating part 7 in contact with the heat radiating surface of the Peltier unit 6, and a cooling part 8 in contact with a cooling surface located on the opposite side of the heat radiating surface. Having a water supply configured; And the water produced | generated in this water supply part is dripped at the upper surface of the trunk | drum 28 of the water application electrode 2, and is supplied.

  The heat dissipating part 7 has a base plate 7a in contact with the Peltier unit 6 and a plurality of heat dissipating fins 7b erected substantially vertically on the surface of the base plate 7a opposite to the Peltier unit.

  The cooling unit 8 includes a base plate 8a that is in contact with the Peltier unit 6 and a plurality of cooling fins 8b that are erected substantially perpendicularly to the surface of the base plate 8a opposite to the Peltier unit.

  The plurality of radiating fins 7b of the radiating unit 7 and the plurality of cooling fins 8b of the cooling unit 8 are substantially orthogonal to the air flow passing through the radiating fins 7b and the cooling fins 8b so as to be substantially parallel to the air flow. Parallel to each other at a predetermined interval in the direction. Here, since the air flow is substantially in the direction of gravity, the plurality of heat radiation fins 7b of the heat radiation unit 7 and the plurality of cooling fins 8b of the cooling unit 8 are arranged in parallel in a substantially horizontal direction that is substantially perpendicular to the direction of gravity. Yes. In order to efficiently cool the cooling unit 8, the heat radiation fin 7 b of the heat radiation unit 7 has a larger fin surface area than the cooling fin 8 b of the cooling unit 8.

  A plurality of P-type N-type semiconductors are alternately connected in series inside the Peltier unit 6. When a DC voltage of about 1 to 5 V is applied from the low voltage power supply unit 5 to the Peltier unit 6, a current flows in one direction, the amount of heat on the heat dissipation surface increases due to the Peltier effect, and heat is absorbed on the cooling surface. Thereby, the thermal radiation part 7 is warmed and the cooling part 8 is cooled.

  When the temperature of the cooling unit 8 is cooled below the dew point of the passing air by the Peltier unit 6, the condensed water 10 in which moisture in the air is condensed is generated on the surface of the cooling fin 8b of the cooling unit 8. .

  Here, below the cooling unit 8 in the direction of gravity, the water application electrode 2 is disposed through a space of a predetermined distance L10 from the lower end of the cooling fin 8b. The cooling unit 8 and the water application electrode 2 do not have a portion in direct contact with each other. The condensed water 10 dripped by gravity from the lower end of the cooling fin 8 b falls on the upper surface of the trunk portion 28 of the water application electrode 2. That is, the substantially rectangular trunk portion 28 of the water application electrode 2 extends in the long side direction in the direction in which the cooling fins 8b are arranged in parallel, and is disposed directly below the cooling fins 8b with a space of a distance L10. It is.

  Condensed water 10 that has fallen by gravity onto the upper surface of the body portion 28 is absorbed into the water application electrode 2 of the metal porous body, and moves inside the gap (pore 21) in which the inside is three-dimensionally connected by surface diffusion. The condensed water 10 is conveyed from the trunk portion 28 to the tip atomizing portion 29 inside the water application electrode 2 by such a surface diffusion phenomenon.

  When water (condensation water 10) is transported to the vicinity of the tip 29a of the tip atomization portion 29 of the water application electrode 2, the water application electrode 2 has a voltage of -4 to -6 kV with respect to the counter electrode 3 that is the ground electrode. Since a negative high voltage is applied, the high voltage is applied to the water near the tip 29a, and the water (condensation water 10) is charged to the same potential as the water application electrode 2, that is, a negative high voltage. Therefore, the charged water is pulled locally from the tip 29a to the outside of the water application electrode 2 by the action of Coulomb force in an electrostatic field, and forms a swell called a tailor cone. At this time, the water forming the tailor cone is attached to the water application electrode 2 and is continuously charged. Then, when the coulomb force acting exceeds the surface tension of water, the water that formed the tailor cone pops out and repeats splitting (this splitting is called Rayleigh splitting), and the nanometer-size charging The electrostatic mist 1 is generated. The electrostatic mist 1 moves toward the counter electrode 3 and is discharged from the opening 3a of the counter electrode 3 to the outside.

  The electrostatic mist 1 generated in this way is simply called mist or fine particle water, or since it is charged, it may be called charged mist or charged fine particle water. Moreover, since the magnitude | size is a nanometer size, it may be called nanomist. In any case, it is a charged nanometer-size mist (particulate water) generated by applying high voltage to water and being refined by Rayleigh splitting. Here, the mist generated in this way It will be referred to as electrostatic mist 1. Moreover, producing | generating the electrostatic mist 1 in this way is called electrostatic atomization, and atomizing is making water mist. The atomization amount is the generation amount (generation amount) of the electrostatic mist 1.

  Since the plurality of cooling fins 8b positioned above and the body portion 28 of the water application electrode 2 positioned below the cooling unit 8 via the gap L10 are in contact with each other, the gravity is Thus, a large amount of condensed water 10 dripped widely in the horizontal direction of the cooling fins 8b from the lower ends of the plurality of cooling fins 8b is reliably received without waste, with the upper surface of the body portion 28 serving as a water receiving surface. Since they can be conveyed to the tip atomizing section 29, a large amount of electrostatic mist 1 can be generated stably.

  If the tip atomizing portion 29 is formed in the middle of the side surface of one long side (the direction in which the cooling fin 8b protrudes) of the body portion 28, the body portion 28 has a larger portion than that provided on the side surface of the short side. The received condensed water 10 can be quickly conveyed to the tip atomizing section 29. For this reason, coupled with the fact that the path from the dew condensation water 10 to the water application electrode 2 is direct dripping onto the body portion 28 due to gravity, the static atomization apparatus 100 can be quietly moved in a short time from the start of operation. Electric mist 1 can be generated. When the same amount of condensed water 10 is dropped from each cooling fin 8b and there is only one tip atomizing portion 29, the tip atomizing portion 29 is placed on the side surface of one long side of the trunk portion 28. And it is most preferable from the stability of conveyance of water to arrange | position in the position corresponded to the center of the lamination direction width | variety of the cooling fin 8b.

  The counter electrode 3 is installed in order to keep the potential difference with the water application electrode 2 constant. However, the counter electrode 3 is not installed and is statically discharged by discharge in the air (discharge from the floating potential in the air). The electric mist 1 may be generated. Further, a member in which the electrostatic atomizer 100 is mounted in advance is a member whose potential is in the vicinity of 0 V (for example, a metal indoor heat exchanger installed inside the indoor unit as being mounted in the indoor unit of the air conditioner) The electrostatic mist 1 may be generated so as to maintain a potential difference from the water application electrode 2 by using the indoor heat exchanger as a substitute for the counter electrode 3.

  Hereinafter, the case where the electrostatic atomizer 100 of this Embodiment is mounted in the inside of the air conditioner 50 is demonstrated. Further, an electrostatic atomizer 150 having a shape suitable for being mounted on the air conditioner 50 will be described in detail as a first modification.

  FIG. 4 shows the first embodiment, and is a longitudinal sectional view of an air conditioner 50 provided with electrostatic atomizers 100 and 150. The air conditioner 50 shown in FIG. 4 is a general wall-hanging type, but is an air conditioner embedded in the ceiling, and is an electrostatic mist upstream of the heat exchanger 51 and downstream of the suction port 41. It may be an air conditioner in which the control device is arranged.

  The air conditioner 50 includes a suction port 41 that sucks indoor air, a blow-out port 42 that blows conditioned air into the room, and an inverted V-shaped heat that generates conditioned air (cooled, heated, or dehumidified air) from the room air. An exchanger 51 (consisting of a front upper heat exchanger 51a, a front lower heat exchanger 51b, and a rear heat exchanger 51c) and a drain pan 40 (front upper heat exchanger 51a, rear heat) that receives water condensed in the heat exchanger 51 2 places below the exchanger 51c) and a blower fan 43. The room air that has flowed in through the rotation of the blower fan 43 from the suction port 41 located above the air conditioner 50 main body is heat-exchanged with the refrigerant of the refrigeration cycle when passing through the heat exchanger 51, and the temperature and humidity are adjusted. Then, the air passes through the blower fan 43 and is blown into the room as conditioned air from the outlet 42 located below.

  A left and right wind direction plate 44 and an up and down wind direction plate 45 that can change the wind direction of the conditioned air to be blown out are installed at the blowout port 42, and the blowout direction of the blowout flow is adjusted. A left and right wind direction plate 44 that can change the wind direction in the left and right direction of the blown flow is located upstream of the vertical wind direction plate 45 that can change the vertical direction of the blown flow. Moreover, the dew condensation water of the heat exchanger 51 collected by the drain pan 40 is discharged outdoors through a drain hose (not shown).

  Here, in the air conditioner 50, the electrostatic atomizers 100 and 150 are either the windward side (upstream side) of the front lower heat exchanger 51b or the windward side (upstream side) of the rear heat exchanger 51c. However, it is installed above the drain pan 40. If the electrostatic atomizers 100 and 150 are installed above the drain pan 40, even if the condensed water 10 in the cooling unit 8 is large and surplus moisture is generated, the drain pan 40 can remove such surplus moisture. Since it is received and discharged to the outside together with the dew condensation water of the heat exchanger 51, there is no possibility that excess moisture of the installed electrostatic atomizers 100 and 150 leaks into the room.

  By installing one of the electrostatic atomizers 100 and 150 in the air conditioner 50, a large amount of electrostatic mist 1 discharged from the electrostatic atomizers 100 and 150 was sucked from the suction port 41. The heat exchanger 51 can be passed along with the room air and discharged into the room together with the conditioned air from the blowout port 42. The electrostatic mist 1 is also discharged into the room together with the conditioned air by riding on a conditioned air blowing flow generated by the rotation of the blower fan 43.

  The outlet 42 of the air conditioner 50 is provided with a left and right wind direction plate 44 and an up and down wind direction plate 45 that can automatically change the direction. The up-and-down wind direction plate 45 is divided into two at the center, and can deliver the wind to two arbitrary depth directions in the room such as the front and back. The left and right wind direction plates 44 are also driven by independent motors (for example, stepping motors) at the left and right portions with the center as a boundary, so that the wind can be delivered to two arbitrary left and right directions in the room. Moreover, a plurality of winds can be created by combining these simultaneously.

  The air conditioner 50 including the electrostatic atomizers 100 and 150 will be described in more detail.

  Although both sides of the Peltier unit 6 are provided with a heat radiating part 7 and a cooling part 8, the cooling part 8 has a sufficiently smaller capacity than the heat radiating part 7. Since the heat dissipation part 7 increases the heat dissipation amount, it is better to make it as large as space allows. However, if the cooling part 8 is too small, the surface temperature will drop, but the amount of air passing will decrease, so the dehumidification amount (condensation amount) will decrease. To do. On the other hand, if it is too large, the passing air volume increases and the dehumidification amount (condensation amount) increases, but the surface air does not drop sufficiently because the passing air has an endothermic ability. The capacity of the cooling unit 8 may be determined according to the required amount of dehumidification, but the absolute humidity in winter (during heating) is very low, the dew point temperature is approximately 10 ° C. or less, and the relative humidity is 30% to 35% RH. It is about 2-5 degreeC in bad conditions of. Therefore, since the condensed water 10 as the raw material of the electrostatic mist 1 cannot be obtained unless the temperature of the cooling fin 8b is lowered to around 0 ° C., the capacity of the cooling fin 8b is made sufficiently smaller than that of the heat radiating portion 7. Is preferred. Further, in order to maximize the heat absorption performance of the Peltier unit 6, it is preferable that the heat radiating section 7 has a volume as large as possible.

  In addition, when installing the electrostatic atomizer 100,150 in the windward side of the heat exchanger 51, it arrange | positions so that the lamination direction of the cooling fin 8b and the radiation fin 7b may become the left-right direction of the air conditioner 50 main body. Good. As a result, the suction air flow from the suction port 41 flows along the fins (cooling fins 8b and heat radiating fins 7b), and the heat radiation of the heat radiating unit 7 is promoted. The amount of condensation increases on the fins 8b.

  Further, when the fin volume is increased, it is only necessary to extend in the width direction (FIG. 5), and it can be realized with a short fin height that is easy to manufacture, and can be installed in a small space without increasing the overall depth. .

  The heat radiating unit 7 is disposed substantially parallel to the position facing the heat exchanger 51. At this time, by making a predetermined gap, it is possible to reduce the thermal effect that occurs when the heat exchanger 51 is heated with respect to the heat radiating section 7. If it receives heat influence, it will become difficult to radiate heat in the heat radiating part 7, and the cooling capacity in the cooling part 8 will fall.

  In addition, by providing a predetermined gap, abnormal discharge does not occur from the counter electrode 3 to the heat exchanger 51. Arranging substantially parallel to the heat exchanger 51 makes it less susceptible to local effects. The predetermined distance is preferably at least 4 mm, and the influence is smaller as the distance is larger, but is determined in consideration of space characteristics.

  The closer to the heat exchanger 51, the higher the wind speed of the suction air flow from the suction port 41. When the electrostatic atomizers 100 and 150 having a thickness of about 10 to 30 mm are installed at a distance of about 4 to 10 mm from the front lower heat exchanger 51b on the windward side of the front lower heat exchanger 51b, the front lower heat exchange is performed. The wind speed in the vicinity of the vessel 51b is about 2 to 3 times faster than the side near the front panel 46.

  Similarly, when installed on the windward side of the back surface heat exchanger 51 c, the wind speed in the vicinity of the back surface heat exchanger 51 c is about 2 to 3 times faster than the side near the back surface cover 47.

  If the heat dissipating part 7 is arranged so as to face the heat exchanger 51, the flow rate of the air (indoor suction air) flowing through the heat dissipating part 7 increases, and the heat dissipation may be further promoted.

  Further, when the cooling unit 8 is arranged farther from the heat exchanger 51 and closer to the front panel 46 or the back cover 47, the flow rate of the air (indoor suction air) flow passing through the cooling unit 8 is reduced to the heat radiating unit 7. In comparison, the temperature of the cooling fins 8b can be lowered to the dew point or less without the heat absorption capability being taken away by the passing air of the cooling unit 8.

  Furthermore, the heat radiating unit 7 is exposed to the air so that the wind can pass well, and the cooling unit 8 is covered with a water supply unit holding frame 60 to prevent excessive air inflow, and on the wind of the cooling fin 8b. Then, the passing air speed and the passing air volume are controlled by one or a plurality of air quantity adjusting holes 61 provided in the width direction.

  By constituting in this way, it is possible to sufficiently dissipate heat without reducing the volume of the heat dissipating part 7 and impairing the space saving, and sufficiently lower the temperature of the cooling part 8 to dry conditions such as during heating. But you can get condensed water.

  This effect can also be obtained when the electrostatic atomizers 100 and 150 are installed on the windward side of the front upper heat exchanger 51a, but pass through the cooling unit 8 on the windward side of the front upper heat exchanger 51a. Since the wind is fast, it is necessary to make the opening of the air amount adjustment hole 61 smaller. The purpose of adjusting the air amount is to reduce the air speed by lowering the air speed. Therefore, the air amount does not need to be the air amount adjusting hole 61, and the air amount may be adjusted by providing an obstructing rib or the like.

  Up to now, it has been explained that the water application electrode 2 made of a porous body is composed of a body part 28 for receiving water and a tip atomizing part 29 connected to the body part 28. The movement of water is smoother if the body 28 and the tip atomizing section 29 are integrally formed of the same material. However, the movement of the water is not necessarily integral, and the body section 28 is provided as a water retaining section for receiving water. Even if the tip atomizing portion 29 is connected and used, there is no problem as long as the tip atomizing portion 29 has a water carrying ability, and various effects described in the present embodiment can be obtained. Can do. The water retaining part is preferably made of a non-woven fabric made of an organic material having water absorption in addition to ceramic.

  Moreover, the automatic filter cleaning apparatus (not shown) which provided the brush and the pad in the top | upper surface direction of the electrostatic atomizer 100,150, or the dust box (not shown) which accommodates the dust scraped off by the automatic filter cleaning apparatus. ), There is a possibility of dust falling on the electrostatic atomizers 100 and 150, so that the water supply unit (heat dissipating unit 7, Peltier) is placed on the top surface of the electrostatic atomizers 100 and 150. A dust receiver may be provided so as to cover the unit 6 and the cooling unit 8).

  Moreover, when arrange | positioning the thermal radiation part 7 facing the heat exchanger 51, the front-end atomization part 29 is the direction opposite to the protrusion direction of the cooling fin 8b on the long side direction side surface by the side of the thermal radiation part 7 of the trunk | drum 28. If it is provided so as to protrude in the direction, the electrostatic mist 1 can be quickly and surely guided to the blowout port 42 on the air flow having a large flow rate passing through the heat radiating portion 7.

  Thereby, many electrostatic mists 1 can be discharged from the outlet 42 in a short time from the start of operation of the air conditioner 50. In this case, a cage 30a is installed above the generation portion of the electrostatic mist 1 as shown in FIG. 5 to suppress the passage of airflow through the heat radiating portion 7 to the generation portion of the electrostatic mist 1. You should do it. Moreover, it is better to install the wall 30b and suppress the passage of the air flow through the cooling unit 8 to the generation part of the electrostatic mist 1.

  Moreover, the electrostatic mist 1 produced | generated by the electrostatic atomizer 100,150 uses the water | moisture content in the air in the room | chamber interior in which the air conditioner 50 in which this electrostatic atomizer 100,150 is mounted as a raw material. In other words, the moisture in the room air is condensed, which is atomized and released into the room, so that the absolute humidity in the room does not increase. Therefore, condensation due to the electrostatic mist 1 discharged to the indoor wall or window does not occur. Therefore, it is possible to suppress the evaporation of human skin moisture and increase the amount of skin epidermis moisture while avoiding the occurrence of mold on indoor walls due to condensation.

  In addition, indoor air is supplied to the Peltier unit 6 of the water supply unit by using the blower fan 43 of the air conditioner 50, and condensed water that becomes the electrostatic mist 1 is obtained there, and the conditioned air from the outlet 42 is supplied. Since the electrostatic mist 1 is provided (released) in the room by being transported in a blow-off flow, there is no need to provide a separate fan dedicated to the electrostatic atomizer, the structure of the electrostatic atomizer is simplified, and the space is small It can be set as the electrostatic atomizer which can also be installed.

  Next, an electrostatic atomizer 150 having a shape suitable for mounting on an air conditioner will be described in detail as a first modification. 5 to 10 show the first embodiment, FIG. 5 is a longitudinal sectional view of the electrostatic atomizer 150 according to the first modification, FIG. 6 is an exploded perspective view of the electrostatic atomizer 150, and FIG. FIG. 8 is a perspective view of the holding frame 70, FIG. 9 is a perspective view of the wind prevention wall 30, and FIG. 10 is a rear view of the electrostatic atomizer 150 of the first modification.

  In the electrostatic atomizer 150 shown in FIG. 5, the tip atomizing portion 29 of the water application electrode 2 is placed on the side surface in the long side opposite to the surface in the protruding direction of the cooling fin 8 b, that is, the fin of the heat radiating portion 7. It is provided so as to protrude in the protruding direction. The counter electrode 3 is also provided on the heat radiating part 7 side so as to face the tip atomizing part 29 at that time. With such an arrangement, there is an additional effect that the electrostatic mist 1 emitted from the opening of the counter electrode 3 can be widely diffused on the air flow passing through the heat radiating unit 7 having a larger flow rate than the cooling unit 8. Is done.

  The main elements constituting the electrostatic atomizer 150 are as follows. Each element has already been described in detail, and those not yet described will be described in detail later, so they will be described briefly here (mainly see the exploded perspective view of FIG. 6).

  (1) Water supply unit: The water supply unit includes the Peltier unit 6 described above, the heat radiation unit 7 in contact with the heat radiation surface of the Peltier unit 6, and the cooling unit 8 in contact with the cooling surface located on the opposite side of the heat radiation surface. Composed. The Peltier unit 6 has a lead wire 6a that is electrically connected to the low-voltage power supply unit 5 (the same as that in FIG. 1).

  (2) Cooling unit holding frame 63: The cooling unit holding frame 63 is made of resin, and fixes the cooling unit 8 of the water supply unit to the heat radiating unit 7 by engagement. Details will be described later.

  (3) Water supply unit holding frame 60: The water supply unit holding frame 60 holds the water supply unit in which the cooling unit 8 is fixed to the heat radiating unit 7 with the cooling unit holding frame 63 from the cooling unit 8 side. The cooling unit 8 is stored in the cooling unit storage unit 60a (see FIG. 7). Further, the heat radiating portion 7 is accommodated in the heat radiating portion accommodating portion 60b (see FIG. 7). The cooling unit 8 is covered with the water supply unit holding frame 60 on the upstream side of the air flow, and the passing air speed and the passing air amount are controlled by a plurality of air amount adjusting holes 61 (air amount adjusting units) provided in the width direction. Furthermore, the water supply part holding frame 60 includes a lead wire lead part 60 c that feeds out the lead wire 25 a connected to the lead wire 6 a of the Peltier unit 6 and the water application electrode 2 via the power supply terminal 25. In addition, the water supply unit holding frame 60 includes blocking walls 62 on the left and right of the cooling unit storage unit 60 a that stores the cooling unit 8. Wind that has passed through a heat radiation exposed portion (not shown) that is a surface that does not have fins of the heat dissipation portion 7 and that is exposed from the Peltier unit 6 on the surface that has the Peltier unit 6 does not reach the cooling portion 8. For this purpose, a blocking wall 62 is provided. Due to the left and right blocking walls 62 of the heat radiating part storage 60 b, the air that has passed through the heat radiating exposed part flows downward without touching the cooling part 8.

  (4) Water supply unit holding frame 90: The water supply unit holding frame 90 is made of resin like the cooling unit holding frame 63, and sandwiches the water supply unit with the cooling unit holding frame 63. Engagement between the water supply unit holding frame 90 and the cooling unit holding frame 63 is performed by a claw and a hole. Further, the water supply part holding frame 90 includes a lead wire lead part 90 a that feeds out the lead wire 6 a of the Peltier unit 6 and the lead wire 25 a of the water application electrode 2 in the same manner as the water supply part holding frame 60. The lead wire lead portion 60 c of the water supply portion holding frame 60 and the lead wire lead portion 90 a of the water supply portion holding frame 90 sandwich the lead wire 6 a of the Peltier unit 6 and the lead wire 25 a of the water application electrode 2.

  (5) Water application electrode 2: The same as the water application electrode 2 of the electrostatic atomizer 100 of FIG. However, in the electrostatic atomizer 150, the tip atomizing portion 29 of the water application electrode 2 is on the side surface in the long side opposite to the surface in the protruding direction of the cooling fin 8b, that is, the fin protruding direction of the heat radiating portion 7. It is arranged to protrude. A lead wire 25 a is connected to the water application electrode 2 via a power supply terminal 25.

  (6) Holding frame 70: The holding frame 70 is a member that holds the water application electrode 2 from below. As will be described in detail later, as shown in FIG. 8, the holding frame 70 has a lattice 70a in the short side direction of the outer periphery and the body portion 28, and has a box shape having a large rectangular opening 26 (see FIG. 8). It has a shape. The lattice 70a extending in the short side direction supports the body portion 28 of the water application electrode 2, but has a width sufficiently shorter than the width of the body portion 28 (long side direction). Further, a counter electrode holding portion 70 b that holds the counter electrode 3 is formed below the holding frame 70. In addition, when water droplets dropped from the body portion 28 fall down along the holding frame 70, they may adhere to the counter electrode 3 when dropped from a portion facing the center of the counter electrode 3 or scattered by wind. There is a danger. Therefore, the lower end portion of the holding frame 70 (the portion that supports the tip atomizing portion 29 of the water application electrode 2) draws a semicircle in the left-right direction with the position facing the center portion of the counter electrode 3 as the apex convex portion. As shown in FIG. 8, the circular arc 70c (FIG. 8) extends and the ends of the circular arc 70c are further extended in the left and right directions (corner portions 70d in FIG. 8). With this configuration, water droplets dripped from the body portion 28 are not dripped from a position facing the central portion of the counter electrode 3, and are guided in the left-right direction through the resin (holding frame 70). Since it is dropped from the end of the arc 70c, even if the bridged water droplets scatter, it is difficult to adhere to the counter electrode 3. The end width of the arc 70c is preferably widened in the left-right direction as much as possible, and is preferably equal to or greater than the width in the left-right direction of the exposed portion of the counter electrode 3 viewed from the tip atomizing portion 29 of the water application electrode 2.

  (7) Counter electrode 3: This is the same as the counter electrode 3 of the electrostatic atomizer 100 of FIG. The counter electrode 3 is fixed to the counter electrode holding portion 70b of the holding frame 70 with screws 3c. A ground lead wire 3 b is connected to the counter electrode 3.

  (8) Wind prevention wall 30: The wind prevention wall 30 engages with the upper part of the holding frame 70 to sandwich the water application electrode 2 with the holding frame 70. The wind prevention wall 30 suppresses the heel 30a that covers the tip atomizing portion 29 and the counter electrode 3 of the water application electrode 2, the root portion of the tip atomizing portion 29 with respect to the trunk portion 28, and the long side of the trunk portion 28 from above. And a wall 30b (first wall) formed extending in the top surface direction (see also FIG. 9).

  Hereinafter, the electrostatic atomizer 150 will be described in more detail. As shown in FIG. 5, the flange 30 a of the wind preventing wall 30 is located above the tip 29 a of the tip atomizing portion 29 of the water application electrode 2, and the direction in which the radiating fins 7 b of the heat radiating portion 7 of the water supply portion protrude. It is provided to extend. Thereby, the wind passing through the heat radiating part 7 of the water supply part is prevented from flowing into the tip 29a of the tip atomizing part 29 of the water application electrode 2.

  It is preferable that the tip 29a of the tip atomizing portion 29 of the water application electrode 2 prevent contamination from being adhered due to long-term reliability. If dirt is attached to the tip 29a, the discharge force is reduced and the generation amount of the electrostatic mist 1 is reduced or the generation is unstable. For this purpose, it is preferable to keep the tip 29a from passing air as much as possible and avoiding contact with the moving air.

  By configuring in this manner, the tip 29a of the tip atomizing portion 29 of the water application electrode 2 is less likely to get dirty because dirt does not pass through it, and the electrostatic mist 1 can be stabilized over a long period of time without lowering the discharge power. Can occur. Further, when the air flow having a large flow rate passes excessively on the tip 29a of the tip atomizing portion 29 of the water application electrode 2, formation of tailor cone of water and Rayleigh splitting is inhibited, and an accurate and stable electrostatic mist is obtained. There is no concern that the occurrence of 1 will be impaired.

  The water application electrode 2 is positioned by sandwiching the root portion of the tip atomizing portion 29 (the portion connected to the body portion 28) between the holding frame 70 and the wall 30b of the wind preventing wall 30. The holding frame 70 has a box shape having a large rectangular opening having a plurality of lattices 70 a in the short side direction of the outer periphery and the body portion 28 of the water application electrode 2. A lattice 70 a extending in the short side direction of the body portion 28 of the water application electrode 2 supports the body portion 28 of the water application electrode 2. The holding frame 70 has a large opening 26 around the water application electrode 2 other than the lattice 70a, so that excessive water can be discharged without accumulating water.

  Further, when water drops dropped from the body portion 28 fall along the holding frame 70, when the water drops are dropped from the portion facing the center of the counter electrode 3 and bridge with the counter electrode 3 or are scattered by wind, There is a possibility of adhering to the counter electrode 3, which is dangerous.

  Therefore, the lower end portion of the holding frame 70 (the portion that supports the tip atomizing portion 29 of the water application electrode 2) is provided with a blocking portion 77 that fills the position facing the central portion of the counter electrode 3 with resin, and from there to the left and right A cavity 78 opened to the outside is provided (see FIG. 10). With this configuration, water droplets dripped from the body portion 28 are not dripped from a position facing the central portion of the counter electrode 3, and are guided in the left-right direction through the resin (holding frame 70). Since it passes through the dripping surplus water drainage path, it does not adhere to the counter electrode 3 even if water droplets scatter. In addition, since the water droplets do not move to the position facing the counter electrode 3, there is no discharge with the counter electrode 3 in the air. It is better to spread the water droplets that have passed through the cavity portion 78 in the left-right direction as much as possible, and it is preferable that the water droplets are guided by ribs in the left-right direction.

  At this time, the position of the closing portion 77 described above is a position facing the central portion of the counter electrode 3 and also a position facing the tip 29 a of the tip atomizing portion 29. By providing the blocking portion 77 that fills the opening with resin, the air that has passed through the air amount adjustment hole 61 passes through the vicinity of the body portion 28 and is then guided to the left and right without passing through directly below. The air circulated by the fan 43 does not travel toward the tip 29 a of the tip atomizing portion 29.

  Therefore, by providing the blocking portion 77 and the hollow portions 78 on the left and right, in addition to the effect of inducing excess water droplets to the left and right to prevent air discharge, the tip of the tip atomizing portion 29 is caused by the circulated air flow. 29a has the effect of preventing dirt.

  In the electrostatic atomizer 150, an air flow in the direction of gravity, that is, from the upper side to the lower side, passes through the heat radiating unit 7 and the cooling unit 8, but the heat absorption amount in the cooling unit 8 is prevented from being lowered and the cooling fin 8b is efficiently In order to lower the temperature, the amount of air flow to the cooling unit 8 (the amount of airflow that passes through) is made smaller than that of the heat radiating unit 7. As a means for realizing this, the heat dissipating part 7 opens the upstream side and does not give airflow resistance to the air flow passing through the heat dissipating part 7. Reduce the air flow by limiting the opening of the inlet. In this way, the flow rate of the air flow passing through the cooling unit 8 is reduced to a slight wind state of about 0.1 m / s by reducing the amount of ventilation, and the air flow is prevented from taking out the cooling heat and flowing out. As a result, the cooling fin 8b can be efficiently cooled.

  And although the flow velocity is very small, since there is an air flow in the cooling unit 8, it will flow in so that new air containing moisture will be exchanged, and the air around the cooling unit 8 will not dry, Condensed water 10 is stably generated on the surfaces of the cooling fins 8b cooled efficiently.

  Since the water application electrode 2 is made of a metal porous body or a water absorbing body, it has the property of transporting the received water to the tip atomizing section 29 regardless of where the condensed water 10 is dripped on the upper surface of the body section 28. . The water application electrode 2 itself has three functions such as a water receiving part, a water transport means, and an atomizing part (a generating part of the electrostatic mist 1). For this reason, it has the effect that water can be quickly gathered in the tip atomization part 29, and can be made electrostatic atomization efficiently and accurately stably.

  In the electrostatic atomizer 150, the water collecting that collects water dripped from the cooling unit 8 in addition to the space between the cooling unit 8 and the upper surface of the body unit 28 exposed toward the cooling unit 8. Condensed water 10 is directly formed by gravity without a member, a guide member for guiding dripping water to the trunk portion 28, or a water retaining member for temporarily collecting dripping water before reaching the trunk portion 28. Is dropped on the upper surface of the body portion 28. There are no elements that hinder the movement of water from the cooling section 8 to the body section 28. Thereby, the dew condensation water 10 produced | generated in the cooling part 8 can be supplied to the water application electrode 2 quickly and reliably in a short time.

  11 to 14 are diagrams showing the first embodiment, FIG. 11 is a longitudinal sectional view showing an electrostatic atomizer 200 according to a second modification, and FIG. 12 is a longitudinal section showing an electrostatic atomizer 300 according to the third modification. FIG. 13 is a longitudinal sectional view showing an electrostatic atomizer 400 according to a fourth modification, and FIG. 14 is a longitudinal sectional view showing an electrostatic atomizer 500 according to a fifth modification.

  First, the main features of the electrostatic atomizer 200 of Modification 2 will be described with reference to FIG.

  That is, the electrostatic atomizer 200 according to the modified example 2 is provided with the electrostatic atomizer 200 on the upstream side of the heat exchanger 51, and the protrusion protruding toward the heat exchanger 51 on the water supply unit holding frame 60 or the like. A portion 65 is provided.

  When the electrostatic atomizer 200 is installed upstream of the heat exchanger 51, since the heat exchanger 51 is grounded, when the heat exchanger 51 is close to the electrostatic atomizer 200, the heat exchanger Under the influence of 51, there was a problem that generation of mist was not stable.

  Further, when the counter electrode 3 of the electrostatic atomizer 200 and the heat exchanger 51 come into contact or approach each other due to an assembly error during manufacturing, the electrostatic atomizer 200 moves toward the heat exchanger 51 in the air. There was a problem that unnecessary discharge was caused, noise and noise were generated, and generation of mist was hindered.

  When the electrostatic atomizer 200 to which a high voltage is applied is provided on the downstream side of the air inlet 41 of the air conditioner and on the upstream side of the heat exchanger 51, the heat exchanger 51 is opposed to a certain distance or more. It is necessary to prevent the electrode 3 from approaching.

  Therefore, in the present embodiment, the convex portion 65 protruding toward the heat exchanger 51 is provided on the frame provided in the vicinity of the counter electrode 3. The frame provided in the vicinity of the counter electrode 3 may be any of the wind prevention wall 30, the water supply unit holding frame 60, and the holding frame 70, as long as the convex portion 65 that faces the heat exchanger 51 can be formed. Good. The material is preferably an insulator that does not transmit electricity, and is preferably integrally formed with the wind prevention wall 30, the water supply unit holding frame 60, and the holding frame 70 to form the convex portion 65. Not only this, if the front-end | tip 65a of the convex part 65 exists between the counter electrode 3 and the heat exchanger 51 and the convex part 65 which can regulate the distance of the counter electrode 3 and the heat exchanger 51 is provided, the convex part 65 will be It may be integrated with any resin.

  The shortest length of the counter electrode 3 and the heat exchanger 51 is defined as L1. The length parallel to L1 and the shortest length of the tip 65a of the convex portion 65 and the heat exchanger 51 is defined as L2. In this case, the tip 65a of the convex portion 65 is disposed at a position where L1> L2 ≧ 0 (see FIG. 11).

  That is, normally, the distance between the counter electrode 3 and the heat exchanger 51 is uniquely determined in the drawing, but there is an assembling error at the time of manufacture, and the counter electrode 3 and the heat exchanger 51 of the electrostatic atomizer 200 are assumed. However, since the convex portion 65 hits the heat exchanger 51 and stops due to the presence of the convex portion 65, L2 = 0, but the distance from the counter electrode 3 to the distance less than (L1-L2) The exchanger 51 does not approach or come into contact.

  Therefore, a spatial distance of (L1-L2) or more can be ensured between the counter electrode 3 and the heat exchanger 51. (L1-L2) is preferably as large as possible, and if it is 30 mm or more, it is satisfactory, but at least a distance of about 1 mm per 1 kV of applied voltage may be taken. As a result, the heat exchanger 51 does not affect the amount of mist generated and is stabilized, and a plurality of effects can be obtained in which unnecessary air discharge from the counter electrode 3 to the heat exchanger 51 does not occur. . By preventing air discharge, it is possible to prevent the occurrence of abnormal noise and noise.

  Next, main features of the electrostatic atomizer 300 of Modification 3 will be described with reference to FIG.

That is, the electrostatic atomizer 300 of the modification 3 is comprised as shown below.
(1) The electrostatic atomizer 300 is provided on the upstream side of the heat exchanger 51.
(2) The convex 65 part which protrudes toward the heat exchanger 51 was provided in the water supply part holding frame 60 grade | etc.,.
(3) The counter electrode 3 is deleted as a constituent requirement, and the electrostatic mist 1 is discharged from the water application electrode 2 toward the air or the heat exchanger 51.

  When the mist is emitted toward the air without providing a special electric field, since the opposing heat exchanger 51 is grounded, when the heat exchanger 51 is close to the electrostatic atomizer 300, heat is generated. There was a problem that mist generation was not stable under the influence of the exchanger 51.

  Further, when the heat exchanger 51 is used as a ground electrode without providing the special counter electrode 3, the distance (distance between the electrodes) between the heat exchanger 51 and the water application electrode 2 of the electrostatic atomizer 300. However, when it fluctuates due to an assembly error, there is a problem that generation of mist is not stable.

  When the electrostatic atomizer 300 to which a high voltage is applied is provided on the downstream side of the air inlet 41 of the air conditioner and on the upstream side of the heat exchanger 51, the heat exchanger 51 has a water mark over a certain distance. It is necessary to prevent approach to the additional electrode 2.

  Therefore, in the present embodiment, the convex portion 65 protruding toward the heat exchanger 51 is provided on the frame provided in the vicinity of the water application electrode 2. The frame provided in the vicinity of the water application electrode 2 may be any one of the wind prevention wall 30, the water supply unit holding frame 60, and the holding frame 70 as long as it can form the convex portion 65 facing the heat exchanger 51. Also good. The material is preferably an insulator that does not transmit electricity, and is preferably integrally formed with the wind prevention wall 30, the water supply unit holding frame 60, and the holding frame 70 to form the convex portion 65. Not only this, if the front-end | tip 65a of the convex part 65 exists between the water application electrode 2 and the heat exchanger 51, and the convex part 65 which can regulate the distance of the water application electrode 2 and the heat exchanger 51 is provided, a convex part will be provided. 65 may be integrated with any resin.

  The shortest length of the water application electrode 2 and the heat exchanger 51 is defined as L3. The length parallel to L3 and the shortest length of the tip 65a of the convex portion 65 and the heat exchanger 51 is defined as L2. In this case, the tip 65a of the convex portion 65 is disposed at a position where L3> L2 ≧ 0 (see FIG. 12).

  That is, normally, the distance between the water application electrode 2 and the heat exchanger 51 is uniquely determined by the drawing, but there is an assembling error at the time of manufacture, and heat exchange with the water application electrode 2 of the electrostatic atomizer 300 is performed. Even if the vessel 51 is likely to approach, the convex portion 65 stops by hitting the heat exchanger 51 due to the presence of the convex portion 65, so that L2 = 0, but the water application electrode up to a distance smaller than (L3-L2) 2 and the heat exchanger 51 do not approach or come into contact with each other.

  Therefore, a spatial distance of (L3-L2) or more can be ensured between the water application electrode 2 and the heat exchanger 51. (L3-L2) is preferably as large as possible, and if it is 30 mm or more, it is satisfactory, but it is preferable to take a spatial distance of at least about 1 mm per 1 kV of applied voltage. If 4-6 kV is applied, 6 mm or more is suitable. As a result, the heat exchanger 51 does not affect the amount of mist generated, and the amount generated is stabilized.

  In particular, when the heat exchanger 51 is used as a ground electrode without providing the special counter electrode 3, the distance (distance between the electrodes) between the heat exchanger 51 and the water application electrode 2 of the electrostatic atomizer 300. Since the mist generation becomes unstable due to fluctuation, it is necessary to provide the tip 65a of the convex portion 65 at a position where L2 = 0. In this case, the shortest length (distance between poles) L3 between the water application electrode 2 and the heat exchanger 51 may be set to a distance that gives an electric field sufficient to cause an electrostatic atomization phenomenon due to the Coulomb force. L3 = 4 It is suitable as about 10 mm. Thereby, a stable mist amount can be obtained.

  Next, main features of the electrostatic atomizer 400 of Modification 4 will be described with reference to FIG.

That is, the electrostatic atomizer 400 of the modification 4 is comprised as shown below.
(1) The electrostatic atomizer 400 is provided on the upstream side of the heat exchanger 51.
(2) The convex 65 part which protrudes toward the heat exchanger 51 was provided in the water supply part holding frame 60 grade | etc.,.
(3) Furthermore, the tip 65a of the convex portion 65 is locked to the pipe 52 (refrigerant piping) of the heat exchanger 51.
(4) The counter electrode 3 is deleted as a constituent requirement, and the electrostatic mist 1 is discharged from the water application electrode 2 toward the air or the heat exchanger 51.

  The problem to be solved in the electrostatic atomizer 400 is the same as that in the electrostatic atomizer 300. In the electrostatic atomizer 400, since the tip 65a of the convex portion 65 is locked to the pipe 52 (refrigerant pipe) of the heat exchanger 51, the minimum length between the tip 65a of the convex portion 65 and the heat exchanger 51 is reduced. When defined as L2, L2 = 0. Moreover, the shortest length of the water application electrode 2 and the heat exchanger 51 is defined as L3 (see FIG. 13).

  Furthermore, by locking the tip 65a of the convex portion 65 to the pipe 52, the shortest length (distance between the electrodes) L3 between the water application electrode 2 and the heat exchanger 51 can be ensured without being affected by an assembly error or the like. Can be fixed to. The water application electrode 2 and the heat exchanger 51 do not approach or come into contact with each other up to a distance smaller than L3. The shortest length (distance between poles) L3 between the water application electrode 2 and the heat exchanger 51 may be set to a distance that gives an electric field sufficient to cause an electrostatic atomization phenomenon due to Coulomb force. L3 = about 4 to 10 mm Is preferred. Thereby, since L3 does not change, a stable mist amount can be obtained.

  Although it is possible to secure the distance between the water application electrode 2 and the heat exchanger 51 even if the number of the convex portions 65 is one, it is preferable to provide at least one each on the left and right of the water application electrode 2. By doing so, stress biased to the left and right is not applied. Preferably, at least one is provided above and below the water application electrode 2. By doing so, stress that is biased up and down is not applied. Therefore, it is better that there are a plurality of convex portions 65.

  The resin thickness at the tip 65a of the convex portion 65 is smaller than the width L6 of the fin 53 and the fin 53 (see FIG. 15), so that the resin is smoothly inserted between the fin 53 and the fin 53 and locked to the pipe 52. can do. The shape of the tip 65 a of the convex portion 65 is preferably an arc shape that follows the pipe 52 so that it can be easily locked to the pipe 52. The arc-shaped gap is preferably equal to or slightly smaller than the diameter of the pipe 52 so as not to be separated from the pipe 52. Further, if a cut is made at the base of the arc shape, the stress at the time of inserting the tip 65a of the convex portion 65 into the pipe 52 or being locked to the pipe 52 is alleviated and the resin breaks. I can protect it.

  The shape of the tip 65a of the convex portion 65 is not limited to the arc shape, but may be other shapes. Since the tip 65a of the convex portion 65 only needs to stop at the pipe 52, the tip 65a of the convex portion 65 is split into two and extended substantially parallel to the pipe 52, and a minute protrusion is provided on the inside to prevent the projection 52 from coming off the pipe 52. It may be the one that has been pressed or simply pressed.

  Further, instead of the entire tip 65a of the convex portion 65, a part of the tip 65a may be inserted between the fin 53 and the fin 53, and the distance L6 between the fin 53 and the fin 53 and the resin thickness of the tip 65a are substantially equal. Even if the tip 65a is inserted and fixed between the fins 53 and 53 while the fins are crushed, the water application electrode 2 does not approach the heat exchanger 51, so that the same effect can be obtained. The effect of keeping the distance between the water application electrode 2 and the heat exchanger 51 constant is higher when locked to the pipe 52.

  In the electrostatic atomizer 400 of the modified example 4 of FIG. 13, the case where the counter electrode 3 is not illustrated is illustrated, but even when the counter electrode 3 is present, by locking the tip 65 a of the convex portion 65 to the pipe 52, Since the shortest length (distance between poles) L1 between the counter electrode 3 and the heat exchanger 51 can be reliably fixed without being affected by an assembly error or the like, a stable mist generation amount can be obtained.

  In the electrostatic atomizers 200 to 400 of FIGS. 11 to 13, the water application electrode 2 and the counter electrode 3 are installed facing the heat exchanger 51, but the water application electrode 2 and the counter electrode 3 are heat exchanged. Even when parallel to the width direction of the vessel 51, the above-described effects can be obtained by applying the convex portion 65 in the same manner.

Further, when there are a plurality of water application electrodes 2 and counter electrodes 3, the shortest length between the counter electrode 3 and the heat exchanger 51 is L1, and the shortest length between the tip 65a of the convex portion 65 and the heat exchanger 51 is L2. The shortest length between the water application electrode 2 and the heat exchanger 51 is defined as L3,
L1> L2 ≧ 0
L3> L2 ≧ 0
By doing so, the stable electrostatic mist 1 can be generated by the convex portion 65.

  Next, main features of the electrostatic atomizer 500 of Modification 5 will be described with reference to FIG.

That is, the electrostatic atomizer 500 of the modified example 5 is configured as shown below.
(1) The electrostatic atomizer 500 is provided on the upstream side of the heat exchanger 51.
(2) The convex part 65 which protrudes toward the heat exchanger 51 was provided in water supply part holding frame 60 grade | etc.,.
(3) The end of the heat radiating part 7 or the cooling part 8 is arranged at a position closer to the heat exchanger 51 than the water application electrode 2 or the counter electrode 3.
(4) The counter electrode 3 is deleted as a constituent requirement, and the electrostatic mist 1 is discharged from the water application electrode 2 toward the air or the heat exchanger 51.

  Conventionally, if the heat exchanger 51 and the heat radiating unit 7 or the cooling unit 8 (hereinafter referred to as a heat sink) provided in the Peltier unit 6 come into contact with each other due to an assembly error during manufacturing, an abnormal time (for example, an indoor unit) The voltage of the commercial power supply (100V or 200V) flows into the Peltier unit due to a failure of the electric circuit (short circuit, etc.), causing the Peltier unit to break. There was a problem that there was a concern.

  In addition, if the heat exchanger and the heat sink provided in the Peltier unit come into contact with each other due to assembly errors during manufacturing, the Peltier unit cannot directly radiate heat due to the direct influence of heat from the heat exchanger during heating operation. There was a problem that the unit did not work properly, the cooling part could not be cooled, and condensed water could not be obtained.

  Therefore, when the heat sink provided in the electrostatic atomizer 500 is provided on the downstream side of the suction port 41 of the air conditioner 50 and on the upstream side of the heat exchanger 51, the heat exchanger 51 is more than a certain distance. It is necessary to prevent it from approaching.

  Therefore, in the present embodiment, the convex portion 65 that protrudes toward the heat exchanger 51 is provided on the frame provided in the electrostatic atomizer 500. The frame provided in the electrostatic atomizer 500 may be any of the wind prevention wall 30, the water supply unit holding frame 60, and the holding frame 70 as long as it can form the convex portion 65 facing the heat exchanger 51. Also good. The material is preferably an insulator that does not transmit electricity, and is preferably integrally formed with the wind prevention wall 30, the water supply unit holding frame 60, and the holding frame 70 to form a convex portion. Not only this, but if the convex part 65 is provided between the heat sink 51 and the heat exchanger 51 and the convex part 65 that can regulate the distance between the heat sink 51 and the heat exchanger 51 is provided, the convex part 65 is integrated with any resin. It may be converted.

  The shortest length of the heat sink and the heat exchanger 51 is defined as L4. The length parallel to L4 and the shortest length of the tip 65a of the convex portion 65 and the heat exchanger 51 is defined as L2. In this case, the tip 65a of the convex portion 65 is disposed at a position where L4> L2 ≧ 0 (see FIG. 14).

  That is, normally, the distance between the heat sink and the heat exchanger 51 is uniquely determined by the drawing, but it is assumed that there is an assembly error at the time of manufacture and the counter electrode 3 of the electrostatic atomizer and the heat exchanger 51 are close to each other. Even if the convex portion 65 exists, the convex portion 65 hits the heat exchanger 51 and stops, so that L2 = 0, but the counter electrode 3 and the heat exchanger 51 become a distance smaller than (L4-L2). Are not in close proximity or touching.

  Therefore, a space distance of (L4-L2) or more can be ensured between the heat sink and the heat exchanger 51. (L4-L2) is preferably as large as possible, and it is satisfactory if it is 10 mm or more, but it is preferable to take a distance of at least 4 mm. As a result, the heat sink is not affected by heat, and a stable heat absorption performance of the cooling unit 8 is obtained. In addition, a plurality of effects that the primary voltage does not flow into the heat sink can be obtained.

  15 to 22 are diagrams showing the first embodiment. FIG. 15 is a plan view when the electrostatic atomizer 150 according to the first modification is mounted on the air conditioner 50. FIG. 16 is an electrostatic diagram according to the first modification. 17 is a partial cross-sectional view when the atomizing device 150 is mounted on the air conditioner 50, FIG. 17 is a cross-sectional view showing a state in which the electrostatic atomizing device 150 is attached to the electrostatic atomizing device holding frame 68, and FIG. FIG. 19 is a plan view of the mist generating unit, FIG. 20 is a front view of the mist generating unit, and FIG. 21 is a plan view of another mist generating unit. FIG. 22 is a front view of another mist generating part.

  As shown in FIGS. 15 and 16, the shape of the surface facing the heat exchanger 51 of the tip 65 a of the convex portion 65 is defined as a plane, and this is defined as a plane portion 66. Further, the width L5 of the flat portion 66 is larger than the interval L6 between the fins 53 of the heat exchanger 51. Usually, the space | interval L6 of the fin 53 of the heat exchanger 51 is about 1.0 mm-1.5 mm. By making the width L5 of the flat portion 66 larger than the interval L6 of the fins 53, the flat portion 66 can be reliably pressed against the heat exchanger 51 when the electrostatic atomizer 150 is close to the heat exchanger 51. . Therefore, the heat exchanger 51 can be prevented from excessively approaching the counter electrode 3, the water application electrode 2, and the heat sink. The width L5 of the flat portion 66 is preferably larger than 3.0 mm. There may be a plurality of convex portions 65.

  In FIG. 17, the convex portion 65 is installed on the electrostatic atomizer holding frame 68 as another installation location of the convex portion 65. The water supply part holding frame 60 of the electrostatic atomizer 150 is provided with a claw part 67 (see FIG. 18), and the electrostatic atomizer 150 is electrostatically fogged by the claw part 67 of the water supply part holding frame 60. The fixing device holding frame 68 is fixed. Although the conventional convex portion 65 is provided in the electrostatic atomizer, the convex portion 65 may be provided in the electrostatic atomizer holding frame 68. Even in this case, it is possible to prevent the heat exchanger 51 from excessively approaching the counter electrode 3, the water application electrode 2, and the heat sink.

  As shown in FIGS. 19 and 20, the mist generating portion includes at least one convex portion 65 on each of the left and right sides in the width direction of the water application electrode 2 or the counter electrode 3. When there is only one convex portion 65, the vicinity of the convex portion 65 is not close to the heat exchanger 51, but a portion far from the convex portion 65 may approach the heat exchanger 51. Therefore, by providing at least one protrusion 65 on each of the left and right sides in the width direction of the water application electrode 2 or the counter electrode 3, the distance from the heat exchanger 51 is regulated on both sides of the water application electrode 2 or the counter electrode 3. It is possible to prevent only one of the side surfaces from approaching the heat exchanger 51. That is, there is an effect that the water application electrode 2 or the counter electrode 3 can be prevented from approaching the heat exchanger 51. The same applies to a heat sink instead of the water application electrode 2 or the counter electrode 3.

  The convex portions 65 provided on the left and right sides in the width direction of the water application electrode 2 or the counter electrode 3 are preferably right side of the water application electrode 2 or the counter electrode 3. The part 65 may be in any position in the vertical direction.

  FIG. 21 and FIG. 22 show another convex portion 65. Here, the shape of the convex portion 65 is extended in the width direction to form a lattice shape. The convex portion 65 was formed in a lattice shape covering the tip of the water application electrode 2 or the entire width direction of the counter electrode 3 on the upstream side of the water application electrode 2 or the counter electrode 3. By covering the entire width direction, when a person reaches out from the upstream side, the water application electrode 2 and the counter electrode 3 cannot be touched, so that an electric shock can be prevented. Further, by forming the convex portion 65 in a lattice shape, the air flow sucked from the suction port 41 flows from the upstream through the lattice and in the vicinity of the counter electrode 3, so that the mist is efficiently conveyed.

  Thereby, the distance between the water application electrode 2 or the counter electrode 3 and the heat exchanger 51 can be regulated, and the water application electrode 2 or the counter electrode 3 can be prevented from approaching the heat exchanger 51. Has an effect. The same applies to a heat sink instead of the water application electrode 2 or the counter electrode 3. The lattice of the convex portions 65 can provide smooth opening of the wind by providing openings parallel to the heat sinks and the fins 53 of the heat exchanger 51, so that mist is efficiently conveyed.

  The air conditioner according to the present invention can prevent unnecessary air discharge and abnormal noise due to fluctuations in the distance between the heat exchanger 51 and the electrostatic atomizer, and is a safe and stable mist generation amount. This has the effect of providing a conversion device.

  As described above, the air conditioner according to the present invention is an air conditioner including a suction port, a heat exchanger, a blower fan, and a blower port, and includes a water supply unit that supplies water, and a water supply A water application electrode that receives the water supplied from the unit and atomizes the water at the tip atomization unit by applying a high voltage, and a counter electrode disposed around the tip atomization unit of the water application electrode, Is provided on the downstream side of the suction port of the air conditioner and on the upstream side of the heat exchanger, and the electrostatic atomizer or the holding frame for holding the electrostatic atomizer is provided on the holding frame for holding the electrostatic atomizer. , A protrusion protruding toward the heat exchanger is provided, and the shortest length of the counter electrode and the heat exchanger is a length parallel to L1 and L1, and the end of the protrusion and the shortest length of the heat exchanger When the height is L2, the end of the convex portion is arranged at a position where L1> L2 ≧ 0. It has the effect of being able to provide an electrostatic atomizer that is safe and stable in the amount of mist generation, which can prevent unnecessary air discharge and abnormal noise due to fluctuations in the distance between the heat exchanger and the electrostatic atomizer. .
