  Therefore, if a good mist is not detected by the electrostatic atomization state detection means 13 even after a lapse of a certain time after applying a high voltage to the high voltage electrode 8, as shown in section B of FIG. The dew point temperature TO24 which is the temperature target of the cooling surface 6a is lowered, and the predetermined Ton / Toff duty of the Peltier element driving power supply 15 is corrected in a direction in which Ton increases. Thereby, the cooling capacity of the Peltier element 6 can be improved, and the cooling surface temperature 25 of the Peltier element 6 can be made to reach the dew point temperature TO24 or less. Regarding the change value of the dew point temperature TO24 and the correction value of Ton in this control, the operating temperature and humidity range of the air cleaning device 1 are divided into a plurality of regions, and the dew point temperature change value and the correction of Ton are divided for each divided region. A value may be set, or may be changed uniformly in all regions.

For example, the control unit 16 obtains 1.4V from the air temperature T1 obtained by the suction temperature detection unit 4 and the relative humidity RH1 of the air obtained by the humidity detection unit 30 based on the table of FIG. In order to generate dew condensation on the high voltage electrode 8 without excess or deficiency, it is necessary to maintain the Peltier element applied voltage obtained while confirming the temperature and humidity of the air and the state of electrostatic atomization. 4 corresponds to the table of FIG. 4, the operating temperature / humidity range of the air cleaning device 1 is divided into a plurality of regions, and a voltage to be applied is assigned to each of the divided regions.

  When a certain amount of time elapses from the start of control of the dew point temperature of the cooling surface 6 a by the Peltier element driving power supply 15, the high voltage electrode 8 disposed on the cooling surface 6 a is also cooled, and dew condensation water 31 is generated on the surface of the high voltage electrode 8. In this state, when the high voltage power supply unit 14 is controlled by the control means 16 and a high voltage is applied between the high voltage electrode 8 and the counter electrode 32 of the electrostatic atomization unit 12, condensed water 31 on the surface of the high voltage electrode 8.

FIG. 10 is a timing chart showing a dew point temperature control method for the cooling surface of the Peltier element of the air purifier for an air conditioner according to the fifth embodiment of the present invention. In addition, about the same part as the said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

The Peltier element driving power supply 15 applies an arbitrary voltage to the Peltier element 6 according to an instruction from the control unit 16 to cool the Peltier element 6. Once the cooling surface temperature 25 of the Peltier element 6 falls within the ± Ta range of the dew point temperature TO24, a voltage obtained in advance by experiments from the air temperature and relative humidity shown in FIG. 9 is applied to the Peltier element 6.

  Reference numeral 27 denotes an output state of the high voltage power supply 14 c, in which a high voltage is applied between the high voltage electrode 8 and the counter electrode 32. Reference numeral 26 denotes a mist generation state obtained from the electrostatic atomization state detection means 13.

  About the temperature control method of the cooling surface 6a of the air purifying apparatus 1 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

I have to let it. Therefore, it is necessary to set an upper limit on the maximum power supply to the Peltier element 6 depending on the operating state of the air conditioner 2. For example, when the upper and lower blades 46 of the air conditioner 2 are operating, 2 W required for this is required. And the power consumption 2 W of the high voltage power supply unit 14 is subtracted, and the maximum power supplied to the Peltier element 6 is 4 W.

12 shows the air temperature and relative humidity obtained from the suction temperature detecting means 4 and the humidity detecting means 30 and the power consumption of the Peltier element 6 when the dew point temperature control of the cooling surface 6a is performed.

Furthermore, considering that the high voltage electrode 8 is cooled by the Peltier element 6 and the condensed water 31 is generated, a short circuit abnormality or an abnormal discharge occurs between the high voltage electrode 8 and the counter electrode 32 due to the accumulation of dust. There is a fear. If the short circuit abnormality or abnormal discharge is left as it is, the worst case is that the electrostatic atomization unit 12 or the air conditioner 2 leads to ignition / smoke. However, the high voltage power supply 14c may cause short circuit abnormality or abnormal discharge. On the other hand, by providing the load current drooping characteristic 41, it is possible to prevent the short-circuit abnormality and the abnormal discharge from continuing.

  That is, the high-voltage power supply 14c has a drooping characteristic that lowers the output voltage and current when the load current exceeds a predetermined value, thereby providing a short-circuit protection device.

  Thereby, even if abnormal discharge or short circuit abnormality occurs between the high voltage electrode 8 and the counter electrode 32 of the electrostatic atomization unit 12, the two abnormalities are not continued in the high voltage power supply 14c. The ignition / smoke of the atomizing unit 12 and the air conditioner 2 can be prevented, and the safety of the air cleaning device 1 can be improved.

(Embodiment 8)
FIG. 14 shows a block diagram of the high voltage power supply unit 14 of the air purifier of the air conditioner according to the eighth embodiment of the present invention.

  In the present embodiment, the high voltage power supply unit 14 includes a high voltage generation circuit 14a having a drooping characteristic and an abnormality detection circuit 14b that detects a short circuit abnormality or a discharge abnormality, and turns on and off the power supply to the high voltage power supply unit 14. The switch 43 and an abnormality display means 42 for displaying the occurrence of an abnormality such as a short circuit or discharge to the user are provided.

  About the air purifier of the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the electrostatic atomization unit 12 that atomizes water condensed on the high voltage electrode 8 to generate mist is disposed at the outlet 45 of the air conditioner 2, the gap between the high voltage electrode 8 and the counter electrode 32 is provided. Considering that a short circuit is caused by dust and abnormal discharge occurs between the two electrodes, or that the high voltage electrode 8 is cooled by the Peltier element 6 to generate dew condensation water, the condensation between the high voltage electrode 8 and the counter electrode 32 occurs. In addition, there is a risk of short circuit abnormality or abnormal discharge. In addition, in the present embodiment, the high voltage generation circuit 14a of the high voltage power supply unit 14 may be short circuit abnormal or abnormal discharge. Therefore, it is possible to prevent the short-circuit abnormality and the abnormal discharge from continuing. Further, when a short circuit abnormality or a discharge abnormality is detected by the abnormality detection circuit 14b, the state of occurrence is transmitted to the control means 16, whereby the control means 16 cuts off the power supply to the high voltage power supply unit 14 with the switch 43. The user can be informed of maintenance / inspection of the electrostatic atomizing unit 12 by the abnormality display means 42.

  Thereby, even if abnormal discharge or short circuit abnormality occurs between the high voltage electrode 8 and the counter electrode 32 of the electrostatic atomization unit 12, the two abnormalities are not continued in the high voltage power supply 14c. It is possible to prevent the unit 12 and the air conditioner 2 from igniting and smoking, and to improve the safety of the air purifier 1 and the air conditioner 2.

  As described above, the air purifier for an air conditioner according to the present invention can realize deodorization by discharge atomization without water supply, and only when the dew point temperature control of the Peltier element is possible. Since the voltage application to the Peltier device is continued, the operation of the air conditioner can be prioritized over the operation of the air purifier, and can be applied to the deodorizing use in spaces such as a living room, a toilet, and a vehicle interior. It can also be applied to deodorizing odors generated from devices such as garbage disposal machines, washing machines and vacuum cleaners.
