A hole 254a in which an oblong window hole penetrating the front and back and a resistor punch hole are integrated is formed so as to correspond to the formation positions of the surface electrode contact 214 and the internal electrode contact 215, respectively.

  The cover plate 254 configured as described above can be held integrally when the ion generating element 210 is fitted into the recess.

  The ion generator 231 is configured by assembling the step-up coil 251, the circuit board 252, and the common case 253 configured as described above and the lid plate 254 to which the ion generating element 210 is fixed as follows.

  First, the step-up coil 251 is inserted into the coil accommodating chamber 253b provided at the bottom of the common case 253 with the protruding side of the high-voltage terminal, ground terminal and input terminal facing upward, and the filling material 255 is evacuated to the coil accommodating chamber 253b. In this way, it is filled and insulated while preventing air bubbles from entering.

  Thereafter, after the filler 255 is dried and solidified, the circuit board 252 is inserted into the common case 253 through the upper opening. In this insertion, the circuit component mounting surface is directed downward, and the four connection holes for connection with the booster coil 251 are aligned above the booster coil 251 fixed to the coil housing chamber 253b, and the circuit board This is performed until the lower surface of 252 abuts against the partition wall 253c and the support edge. After this insertion, the tips of the high-voltage terminal, the ground terminal, and the input terminal protruding from the connection hole are welded from the upper surface of the circuit board 252 to the corresponding positions.

The lid plate 254 is attached at a position separated from the upper surface of the substrate 252 by an appropriate length so as to cover the opening of the common case 253.

  After this attachment, the filler 255 is introduced through the window hole 254b opened in the lid plate 254, and the filler 255 is filled in the space between the substrate 252 and the substrate 252 and the ion generating element 210. The ion generator 231 is completed after insulating molding between the two and waiting for the filler 255 to dry and solidify.

  As shown in FIGS. 9 and 10, the surface electrode 213 is formed as a grid electrode in order to increase the amount of ions generated with the application of the driving voltage as much as possible. The internal electrode 212 is formed in alignment with the center of the surface electrode 213 and is a strip electrode having a length and width smaller than that of the surface electrode 213. This shape also contributes to an increase in the amount of ions generated.

  For example, a line width of 0.25 mm is formed on the surface of a dielectric 211 having a size of about 15 mm × 37 mm × 0.9 mm formed by overlapping an upper plate 211a and a lower plate 211b each having a thickness of about 0.45 mm. A grid-shaped surface electrode 213 having a size of about 10.4 mm × 28 mm is formed at a pitch of 0.8 mm, and a size of about 6 mm × 24 mm is formed between the upper plate 211a and the lower plate 211b. A planar internal electrode 212 having a thickness is formed, and a drive voltage of a high voltage current having a frequency of approximately 3.5 KV (peak value) and 90 kHz is applied between them, and is generated between both electrodes 212 and 213. When measured at a position 25 cm away from the ion generating element 210 due to the action of corona discharge, positive ions and negative ions exceeding 200,000 / cc are respectively measured. It was confirmed that emissions will occur. This amount of ion generation is sufficient to function as air cleaning for a room of a general size.

In the water storage part 42, the vaporization of water is promoted from the surface of the water absorption filter 52, and moist air is supplied to the living space. At this time, when the heater 20 is energized, the air flowing on the surface of the water absorption filter 52 is heated, and the amount of humidification can be increased. Further, by driving the ion generator 231, the blue LED 25 is lit, positive and negative ions are supplied together with humidified air, and bacteria floating in the air can be sterilized by the positive and negative ion action.
