  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  First, the whole structure of the air conditioner 1 of a present Example is demonstrated using FIG. FIG. 1 is a configuration diagram of an air conditioner 1 of this embodiment, and FIG. 2 is a side sectional view of the indoor unit 2 of FIG.

  In FIG. 1, an air conditioner 1 is configured by connecting an indoor unit 2 and an outdoor unit 3 with a connection pipe 9, and air-conditions the room. Basic internal structures such as a blower fan 10, a filter 11, a heat exchanger 12, a dew tray 13, an up / down wind direction plate 14, and a left / right wind direction plate 15 are attached to the housing 4 of the indoor unit 2. And basic internal structures, such as the ventilation fan 10 attached inside the housing | casing 4, are included in the indoor unit 2 by attaching a decorative frame. A front panel 6 is attached to the front face of the decorative frame. Below the front panel 6, a display unit for displaying the driving situation and a light receiving unit for receiving infrared operation signals from a separate remote controller 5 are arranged.

  In FIG. 2, by operating the blower fan 10, air flows as indicated by white arrows, and dust in the passing air is collected by the filter 11. The filter 11 is for removing dust contained in the sucked indoor air, and is arranged so as to cover the suction side of the heat exchanger 12. The blower fan 10 is disposed in the center of the indoor unit 2 so as to suck room air from the air suction port 8 and blow it out from the air blowing port 7. The heat exchanger 12 is disposed on the suction side of the blower fan 10 and has a substantially inverted V shape. The heat exchanger 12 changes the temperature by passing the refrigerant from the outdoor unit 3. When the air conditioner is cooled and dehumidified, the heat exchanger 12 is cooled, and by operating the blower fan 10 on the cooled heat exchanger 12, the air flowing as indicated by the white arrow is cooled and the room is air conditioned. Can do. However, when the heat exchanger 12 is below the dew point temperature of the indoor air at this time, water adheres to the heat exchanger 12 due to condensation of moisture in the air, and when the condensed moisture increases, it droops to the dew tray 13. It is structured to discharge outside. Moisture accumulated in the dew tray 13 flows through a drain hose attached to the dew tray 13 and is discharged outside the room.

  Next, the electrostatic atomizer of an Example is demonstrated using FIG. 3, FIG. FIG. 3 is a schematic configuration diagram of an electrostatic atomizer for an indoor unit showing an embodiment, and FIG. 4 is a side cross-sectional view of a water generation unit of the atomizer for the indoor unit.

  The electrostatic atomizer includes a high-voltage generator 29, a conductor 30 extending from a high-voltage terminal 31 of the high-voltage generator 29, and an atomizing electrode that is in electrical contact with the conductor 30 at the time of water absorption at the atomization connection 26. 25, an ion electrode 27, and a water generation unit for water supplied to the atomization electrode 25.

  A high voltage of −3 kV to −6 kV generated by the high voltage generator 29 is applied to the atomizing electrode 25 and the ion electrode 27, and the water supplied from the water generating unit is made fine particles from the tip of the atomizing electrode 25, and Charge and release. Further, ions are released from the ion electrode 27.

  The water generation unit is a method of condensing moisture from air using the Peltier effect. A cooling plate 22 is attached to the low temperature portion 20 of the Peltier element 19, and a heat sink 17 for heat dissipation is attached to the high temperature portion 18. Here, the base plate 34 of the heat sink 17 for heat dissipation is disposed so as to be in close contact with the Peltier element 19. A heat conductive material such as silicon grease is provided between the heat dissipation side of the Peltier element 19 and the heat sink 17 for heat dissipation in order to improve adhesion. This is to improve the heat conduction by filling a fine uneven space between the heat dissipation side of the Peltier element 19 and the heat sink 17 for heat dissipation. In this embodiment, the Peltier element 19 and the heat sink 17 for heat dissipation are in close contact with each other not only when the Peltier element 19 and the heat sink 17 for heat dissipation are in direct contact but also through a heat conductive material such as silicon grease. It also includes the case of touching.

  As shown in FIG. 3, the cooling plate 22 is in close contact with the low temperature portion 20 of the Peltier element 19 with an insulating sheet 21 interposed therebetween, and cools and condenses moisture in the surrounding air. When a certain amount of water adhering to the cooling plate 22 is accumulated, it is dropped by gravity to the water-absorbing water transport member 24 provided under the cooling plate 22 and sent from the water-absorbing water transport member 24 to the discharge portion 28. The water generation part is composed of the above constituent members. Here, in order to increase the heat absorption amount of the Peltier element 19 and improve the water condensation amount, it is important to improve the heat dissipation performance of the heat sink for heat dissipation. The heat radiation of the heat sink 17 for heat radiation of this embodiment is not due to heat radiation by forced ventilation of a fan or the like in order to reduce the number of components and cost, but is due to natural convection of the installation site, and the air flow due to natural convection is shown in FIG. , The hatched arrows shown in FIG.

  Below, an example using the water generation part of the electrostatic atomizer using the heat sink for heat dissipation of this invention is shown.

  In FIG. 5, a heat radiating fin 35 extending from one side is provided on the base plate 34 of the heat sink 17 for heat dissipation that is in close contact with the Peltier element 19, and the base plate 34 that is away from the Peltier element 19 is centered on the base plate 34 and both sides of the base plate 34. The heat dissipating fins 35 are extended. The normal heat sink 17 is the heat sink 17b or 17c shown in FIG. 6 or 7, the base plate 34 extends in one direction, and the heat dissipation fin 35 extending from the base plate 34 is also shown in FIG. As shown in FIG. 7, the horizontal side or the vertical side like the heat sink 17c for heat dissipation shown in FIG. When the heat sink 17b shown in FIG. 6 is replaced with the heat sink shown in FIG. 4, the direction of natural convection is in the direction of the hatched arrow, and it is difficult for ambient air to flow between the heat sink fins, resulting in a significant reduction in heat dissipation performance. To do. In contrast, in the heat sink 17c for heat dissipation shown in FIG. 7, the heat dissipating fins 35 extending from the base plate 34 are on the vertical side, so that natural convection occurs in the direction of the hatched arrow, and the heat dissipating fins compared to the heat sink 17b for heat dissipating in FIG. The amount of ambient air flowing in between increases, heat exchange can be performed smoothly, and heat dissipation efficiency improves. Further, in order to improve the heat dissipation efficiency over the heat sink 17c for heat dissipation, it is necessary to improve the heat dissipation efficiency from the heat dissipation fin 35. In the heat sink 17a for heat dissipation in FIG. By adopting a structure in which the fins 35 are extended, heat from the base plate 34 can be easily transmitted to the heat dissipating fin temperatures on both sides, and heat dissipating efficiency can be improved.

  Further, when the air conditioner 1 is in operation, the blower fan 10 rotates to generate very small vibrations. In some cases, the fine vibration causes resonance vibration and abnormal noise at a component part constituting the air conditioner and a contact portion where the parts are combined. This vibration affects various locations inside the indoor unit 2, and as a countermeasure against this, a soundproofing material or a sound absorbing material is attached, which causes a cost increase. The heat sink 17 for heat dissipation used in this embodiment is one of the parts that are affected by micro vibration. A heat radiating fin 35 extending from one side to a base plate 34 of the heat radiating heat sink 17 that is in close contact with the Peltier element 19 like the heat radiating heat sink 17a and a base plate 34 that is separated from the Peltier element 19, and radiating fins from both sides of the base plate 34. 35 is extended. In this way, by setting the fin length of each radiating fin 35 to a different length, the inherent vibration frequency of each radiating fin 35 is made different. Since the specific vibration frequency of each radiating fin 35 is made different, even if the radiating fin 35 tries to resonate due to slight vibration, the resonance is suppressed and the effect of suppressing the generation of ions can be obtained. Further, the base plate in a portion between the base plate 34 that is in close contact with the Peltier element 19 and the base plate (parallel portion) that is separated from the Peltier element 19 like the heat sink 17a for heat dissipation has an inclined portion. Thus, the lengths of the radiation fins 35 sandwiching the base plate of the inclined portion are arranged so as to be gradually different. Thus, since the length of the radiation fin 35 changes gradually, the natural vibration frequency of each fin will differ and the resonant vibration between each fin can be suppressed.

  In addition, the natural vibration frequency of the radiating fin 35 provided on one side of the base plate 34 in close contact with the Peltier element 19 and the radiating fin 35 provided on both sides of the base plate (parallel portion and inclined portion) separated from the Peltier element 19. Are separated by the natural vibration frequency of the heat dissipating fin 35 provided in the inclined portion therebetween. Accordingly, the heat sink for heat dissipation hardly resonates even when vibration is applied from the outside, and the effect of suppressing the resonance is increased.

  In addition, the base plate having the inclined portion in the portion between the base plate 34 that is in close contact with the Peltier element 19 and the base plate (parallel portion) separated from the Peltier element 19 is stronger than the linear base plate. Since the natural vibration frequency of the large inclined portion is different from the natural vibration frequency of the linear base plate, it is difficult to resonate at this point.

  In addition, as an embodiment for suppressing the resonance vibration, as in the heat dissipation heat sink 17 shown in FIG. 8, the resonance vibration can be suppressed by setting the fin lengths to different lengths as a stepped structure of the heat dissipation fin 35a and the heat dissipation fin 35b. it can.

  FIG. 9 is a diagram showing the relationship between the mounting positions of the Peltier element 19 and the heat sink 17 for heat dissipation, and the weight distribution of the heat sink 17 for heat dissipation is lost by mounting the Peltier element 19 and the heat sink 17 to be shifted in the axial center. Resonant vibration due to vibration of surrounding parts can be suppressed.

As a description of the heat dissipation effect of the heat sink for heat dissipation of the present invention, the results of measuring the surface temperature of the cooling plate provided with the heat sink for heat dissipation are shown below. 10, when the electrostatic atomizer is operated for 30 minutes in a constant temperature room 24 ° C. and 35% RH, the heat radiation fin 35 extending from one side to the base plate 34 of the heat sink 17 for heat radiation in FIG. As shown in FIG. 6, the cooling plate temperature 36a using the heat radiation heat sink 17a with the heat radiation fins 35 extended from both sides of the base plate 34, and the heat radiation fin 35 extending from one side to the base plate 34 of the heat radiation heat sink 17 in FIG. The temperature change of the cooling plate temperature 36b using the heat sink 17b for heat radiation, and the temperature of the cooling plate temperature 36c using the heat sink 17c for heat radiation in which the heat radiation fin 35 extending from one side to the base plate 34 of the heat sink 17 for heat radiation shown in FIG. It is shown. In this embodiment, the heat sink size for heat radiation is 43 mm × 150 mm × 21 mm, the thickness of the heat radiating fin is 1 mm, the fin pitch is 7 mm, a current of 2.0 A voltage of 2.7 V is applied to the Peltier element 15 mm × 15 mm × 3.4 mmt, The temperature change of the surface temperature of the cooling plate surface area of 589 mm ² was measured.

  The temperature of the cooling plate 22 when the electrostatic atomizer is operated for 30 minutes is as follows: the heat radiation heat sink 17b in which the heat radiation fin 35 is disposed on the lateral side and the heat radiation heat sink 17c in which the heat radiation fin 35 is disposed on the vertical side. By disposing 35 on the vertical side, the temperature of the cooling plate 22 can be lowered by 1 ° C. The heat radiation efficiency can be improved by reducing the air resistance between the heat radiation fins by disposing the heat radiation fins 35 on the vertical side and reducing the air resistance between the heat radiation fins. Further, the heat radiation fin 35 is disposed on the vertical side, extends from the base plate 34 of the heat sink 17 to both sides, and uses the heat sink 17a for improving heat conduction from the base plate 34. The temperature of the cooling plate 22 is 4 ° C. lower than the heat sink 17c for heat dissipation in which the heat dissipating fins 35 are arranged on the vertical side, and the efficiency of the heat dissipating fins can be further improved. The fin pitch of the heat radiation fins 35 of the heat sink 17 for heat radiation is preferably 4 to 8 mm, and more preferably 6 and 7 mm. As shown in FIG. 3, the heat sink 17 for heat dissipation in the present embodiment has a structure for releasing heat by natural convection. In this case, if the fin pitch is narrowed, the air flow due to natural convection between the fins is deteriorated, heat cannot be taken from the heat sink 17 for heat dissipation, and the heat dissipation efficiency is deteriorated. On the other hand, if the fin pitch is increased, the fin heat transfer area is insufficient with respect to the air passing amount between the fins, and the heat dissipation efficiency is deteriorated, and the fin pitch of 6, 7 mm is optimal.

  Furthermore, it is desirable to subject the surface of the heat sink 17 for heat dissipation to an oxide film treatment as a means for improving the heat dissipation efficiency. The heat sink 17 for heat dissipation generally uses an aluminum material for reasons of cost reduction and thermal conductivity. If the surface of the aluminum is smooth and glossy, light is reflected and the emissivity is lowered. For this reason, applying an oxide film treatment changes the surface state, suppresses reflection of light, and improves the emissivity. This is because heat absorption due to radiation and heat dissipation are improved. Furthermore, in order to suppress light reflection, it is desirable to perform a black oxide film treatment. This is because the reflection of light can be further suppressed by using black, and the radiation rate is improved.

  Since the present invention has the configuration as described above, it has the following effects. That is, in the water generation part of the electrostatic atomizer of the air conditioner, heat dissipation comprising a heat dissipation fin extending to one side from the base plate of the heat sink for heat dissipation contacting the heat dissipation side of the Peltier element and a heat dissipation fin extending to both sides centering on the base plate By reducing the heat sink space and improving the heat dissipation efficiency, the Peltier element cools the cooling plate to secure a large amount of moisture condensation for heat dissipation, and a large amount of moisture is transferred to the atomizing section. Can be supplied with.
