  By the way, although the electrostatic atomizer of patent document 1 is useful at the point which can obtain the disinfection and deodorizing effect at a high level using water, it has the fault that it will stop functioning, if water is lost. ing. In order to compensate for this drawback, Patent Document 1 uses a Peltier element, and uses condensed water generated on the low temperature side of the Peltier element in an electrostatic atomizer.

  However, if the air is dry as in winter, for example, the amount of water vapor in the atmosphere where the low temperature side of the Peltier element is placed is small, and sufficient condensed water cannot be obtained. There are cases where it is impossible.

  In other words, the oxygen-enriched film has a property of allowing oxygen to pass more than water nitrogen and also allowing water vapor to pass better. Therefore, the oxygen-enriched air that has passed through the oxygen-enriched film contains more water vapor per unit volume than the atmosphere, and the air containing more water vapor flows through the oxygen-enriched air passage. And since the electrode part of the electrostatic atomizer faces the part where air containing a lot of water vapor flows in the passage for oxygen-enriched air, charged fine water particles are easily generated by the electrostatic atomizer.

  According to this configuration, the electrostatic atomizer can be operated in a state where air containing a large amount of water vapor flows, so that charged water particles can be obtained immediately after the electrostatic atomizer is activated. Become.

  According to the first invention, since the electrostatic atomizer is disposed in the oxygen-enriched air passage through which the oxygen-enriched air obtained through the oxygen-enriched membrane flows, it is contained in the oxygen-enriched air in a large amount. Can be supplied to the electrostatic atomizer. Thereby, even if the humidity of the atmosphere is low as in winter, the electrostatic atomizer can function effectively to supply charged water particles into the room, and the indoor environment can be improved.

Moreover , since the water condensed by the low temperature part of the thermoelectric element can be supplied to an electrostatic atomizer, the particle | grains of the charged water can be obtained reliably. Moreover, the temperature of the low temperature part of a thermoelectric element can fully be reduced using the air with low oxygen concentration effectively .

  The Peltier element 53 is connected to the control device 5 as shown in FIG. The control device 5 is configured to apply a voltage to the Peltier element 53. The output voltage from the control device 5 changes. When the output voltage of the control device 5 is set so that the temperature of the low temperature portion 53b of the Peltier element 53 is lower than the dew point of the surrounding air, water vapor contained in the surrounding air is condensed on the surface of the low temperature portion 53b. As a result, condensed water is generated.

  The upper end portion of the heat dissipating fin 54 is formed in a disk shape having a diameter larger than that of the Peltier element 53, and this disk-shaped portion is a lower surface of the Peltier element 53, that is, a high temperature portion as shown in FIG. 53a is fixed.

  The cover part 62 is formed by molding a non-conductive resin material, and has a cylindrical shape with substantially the same diameter as the cylindrical part 58. The lower end portion of the cover portion 62 is fixed to the upper surface of the closing plate portion 59. The upper end portion of the cover portion 62 is located above the discharge electrode 61. As shown in FIG. 7, a plurality of ventilation holes 62 a are formed in a predetermined region in the circumferential direction of the cover portion 62 at intervals in the vertical direction.

  The counter electrode 63 is formed by forming a conductive metal material into a ring shape having substantially the same diameter as the cover portion 62, and is fixed to the upper end portion of the cover portion 62. The counter electrode 63 is connected to a high voltage generator (not shown) configured in the control device 5. The closing plate 59 is grounded.

  As shown in FIG. 6, the oxygen enrichment device 48 includes an oxygen enrichment unit 66 having an oxygen enriched film and a pump 67. The oxygen enrichment unit 66 is disposed in the sub duct 56, and the pump 67 is disposed in the driver side side vent duct 36.

  The oxygen-enriched film is composed of an organic polymer film, and oxygen-enriched air can be obtained by utilizing a difference in velocity of molecules passing through the film when air is passed. In this embodiment, a nonporous silicon polymer film is used as the oxygen-enriched film, but the present invention is not limited to this. By providing a pressure difference between the surface on one side and the surface on the other side of the oxygen-enriched membrane, air is dissolved in the oxygen-enriched membrane, and the oxygen concentration is determined by the speed ratio when the air diffuses in the membrane. Are separated into relatively high oxygen enriched air and relatively low oxygen concentration air. The separation ratio of oxygen to nitrogen is about 2.5. The oxygen-enriched membrane passes water vapor better than nitrogen, and the separation ratio of water vapor to nitrogen is about 22. The oxygen-enriched air refers to air having an oxygen concentration higher than the oxygen concentration in the atmosphere. In this embodiment, the oxygen concentration is about 30%.

  The suction pipe 67 a of the pump 67 communicates with the downstream space of the oxygen enriched film in the oxygen enrichment unit 66. The suction pipe 67a sucks the oxygen-enriched air that has passed through the oxygen-enriched film. The downstream end of the discharge pipe (discharge section) 67 b of the pump 67 is positioned upstream of the electrostatic atomizer 47 in the driver seat side vent duct 36.

  Low oxygen air other than oxygen-enriched air is discharged from the oxygen-enriched unit 66 to the sub duct 56.

  The blower 49 is disposed upstream of the oxygen enrichment unit 66 in the sub duct 56. By this blower 49, the atmosphere is sent to the oxygen enrichment unit 66, and the low oxygen air exhausted from the oxygen enrichment unit 66 is sent to the downstream side of the sub duct 56 and exhausted to the outside.

  The pump 67 and the blower 49 are connected to the control device 5, and ON and OFF are individually switched based on a signal output from the control device 5.

  The control device 5 is connected to an ON / OFF switch 65 of the indoor purification device 4. When detecting that the ON / OFF switch 65 is operated, the control device 5 is configured to simultaneously operate the electrostatic atomizer 47, the oxygen enricher 48, and the blower 49.

  The control device 5 is connected to an indoor air temperature sensor 68 for detecting the indoor temperature and various operation switches 69. Examples of the various operation switches 69 include a temperature setting switch, a blow mode switching switch, and an inside air circulation switch. The control device 5 is configured to determine the target temperature of the conditioned air based on the input signals of the sensor 68 and the switch 69. Then, the control device 5 controls the electromagnetic clutch 23a and the temperature adjusting actuator 33 of the compressor 23 so that the temperature of the conditioned air becomes the target temperature. Further, when in the automatic mode, the control device 5 changes the voltage applied to the fan drive motor 17 so that the air-conditioning air volume becomes an optimal air volume commensurate with the target temperature, and the optimal blowing mode is set. The doors 40 to 42 are controlled. In addition, a passenger | crew can also switch to the arbitrary blowing modes by the blowing mode changeover switch in the said blowing mode.

  Next, the operation of the air conditioner 1 configured as described above will be described. When in the automatic mode, the control device 5 determines the target temperature of the conditioned air based on the set temperature and the indoor temperature state, operates the temperature adjustment actuator 33, rotates the fan drive motor 17, The air-conditioning wind blowing mode is set and the blowing mode switching actuator 43 is operated.

  Further, when the control device 5 detects that the ON / OFF switch 65 is turned on, the control device 5 operates the pump 67 and the blower 49 of the oxygen enrichment device 48, and causes the Peltier element 53 and the electrostatic atomization unit 52 to operate. Apply voltage. The voltage applied to the Peltier element 53 is set so that the low temperature part 53b has a temperature lower than the dew point of the conditioned air, and this value is obtained in advance for each temperature and air volume of the conditioned air by simulation or the like. Value.

  When the air blower 49 is operated, outdoor air flows into the sub duct 56 and is sent to the oxygen enrichment unit 66. This atmosphere passes through the oxygen-enriched film by the suction force of the pump 67. The oxygen-enriched air generated in the oxygen-enriching unit 66 is sucked by the suction pipe 67a of the pump 67 and flows into the driver side side vent duct 36 from the discharge pipe 67b. When the blowing mode of the air conditioner 1 is in the vent mode, the oxygen-enriched air in the driver side side vent duct 36 flows downstream by the conditioned air.

  The oxygen-enriched air in the driver seat side vent duct 36 flows into the cover part 62 from the vent hole 62a of the cover part 62 of the electrostatic atomizer 4. The air flowing into the cover 62 is cooled to the dew point or lower by the low temperature part 53b in the dew condensation water storage part 51, and water vapor contained in the air is condensed on the surface of the low temperature part 53b to obtain dew condensation water. At this time, the oxygen-enriched air contains more water vapor per unit volume than the air, so that even if the air is dry as in winter, the condensed water generation of the electrostatic atomizer 4 is generated. It becomes possible to generate dew condensation water early in the part 50.

  When the lower end portion of the discharge electrode 61 comes into contact with the dew condensation water stored in the dew condensation water storage unit 51, the discharge electrode 61 sucks the dew condensation water to the upper end side by a capillary phenomenon. The sucked condensed water is split at the upper end of the discharge electrode 61 by the voltage applied to the electrostatic atomizer 52 and becomes fine particles having a particle size of nanometer (nm). Between the discharge electrode 61 and the counter electrode 63, negative ions are generated simultaneously with the splitting of the condensed water. As a result, the split water particles are charged and charged. The charged water particles generated in this manner are discharged from the upper end opening of the cover 62 by the conditioned air flowing into the cover 62 through the ventilation holes 62a. And then it spreads indoors from the vent outlet 36a on the driver's seat side.

  On the other hand, the low oxygen air discharged from the oxygen enrichment unit 66 is sent to the downstream side of the sub duct 56 by the blower 49 and hits the heat radiation fins 54 of the electrostatic atomizer 47. The heat dissipating fins 54 are cooled by the low oxygen air, and the high temperature portion 53a of the Peltier element 35 is effectively cooled. The low oxygen air is discharged from the sub duct 56 to the outside of the room.

  When the dew condensation water amount detection sensor 60 detects that the dew condensation water in the dew condensation water storage unit 51 has decreased, the control device 5 increases the voltage applied to the Peltier element 53. Thereby, the temperature of the low temperature part 53b falls further, it becomes possible to obtain more condensed water in a short time, and to store it in the condensed water storage part 51, and the condensed water of the condensed water storage part 51 is lost. Can be avoided. On the other hand, when there is a sufficient amount of condensed water stored, there is no need to newly obtain condensed water. Therefore, by reducing the voltage applied to the Peltier element 53 or setting it to 0, wasteful power consumption is suppressed.

  As described above, according to this embodiment, since the electrostatic atomizer 47 is disposed in the driver side side vent duct 36 through which the oxygen-enriched air obtained by passing through the oxygen-enriched membrane flows, Charged water particles can be generated by using the water vapor contained in the enriched air. As a result, even when the humidity of the atmosphere is low as in winter, the electrostatic atomizer 47 can function effectively to supply charged water particles into the room, and the indoor environment can be improved.

  Further, since the water vapor in the oxygen-enriched air can be condensed by the low temperature portion 53b of the Peltier element 53, charged water particles can be obtained with certainty. In addition, the temperature of the low temperature portion 53b of the Peltier element 53 can be sufficiently lowered by effectively using low oxygen air.

  Further, since the oxygen enricher 48 and the electrostatic atomizer 47 are interlocked, the oxygen enricher 48 generates air containing a large amount of water vapor, and supplies this air to the electrostatic atomizer 47. Thus, the electrostatic atomizer 47 can always be operated effectively.

  In the above-described embodiment, the oxygen enricher 48 and the electrostatic atomizer 47 are interlocked. However, the present invention is not limited to this. For example, the electrostatic atomizer 47 after the oxygen enricher 48 is activated. May be operated. By doing in this way, it becomes possible to operate the electrostatic atomizer 47 in a state in which air containing a large amount of water vapor flows through the electrostatic atomizer 47, so electrostatic particles of charged water are electrostatically atomized. It can be obtained immediately after the operation of the device 47, and the electrostatic atomizer 47 can be operated efficiently.

  In this embodiment, the amount of condensed water stored in the condensed water storage unit 51 is detected by the condensed water amount detection sensor 60. However, the amount of condensed water on the surface of the low temperature portion 53a is directly detected by the condensed water amount detection sensor 60. You may make it detect.

  Further, the oxygen enricher 48 and the electrostatic atomizer 47 may be operated simultaneously with the start of the operation of the air conditioner 1 instead of operating the ON / OFF switch 65.

  Moreover, although the said embodiment demonstrated the case where the indoor purification apparatus 4 was integrally provided in the air conditioning apparatus 1, it is not restricted to this, The indoor purification apparatus 4 is comprised separately from the air conditioning apparatus 1, and only the indoor purification apparatus 4 is comprised. Can also be provided indoors.

  Moreover, although this embodiment demonstrated the case where this invention was applied to a vehicle, this invention is applicable also to a general residence, a store, an office, etc.

  As described above, the indoor purification apparatus according to the present invention can be used, for example, to purify the interior of an automobile.
