風量を増加して浄化を素早く行なうようにしてもよい。The ventilation fan 7 creates an air flow that takes in air from the air inlet 2 and causes it to flow out to the air outlet 8. For example, a sirocco fan, an axial fan, or the like can be used. A smoke sensor may be provided, and the switch (S1) of the ventilation fan 7 may be turned on when a predetermined amount or more of smoke is detected by the signal processing control means connected to the smoke sensor, and may be turned off during normal operation. . If it is turned off during normal operation and the operation is performed only by the ion wind, there is no noise from the rotation of the ventilation fan 7, and the operation is particularly suitable for nighttime operation. Alternatively, when a predetermined amount or more of smoke is detected, the amount of air passing through the inside of the apparatus may be increased by increasing the number of revolutions, or the like, so that purification can be performed quickly.

A DC high voltage of １２12 kV is applied, lines of electric force are generated between the two poles, and ionic wind is generated from the ionization electrode 4 to the dust collection electrode 6. Dust comes into contact with gas ions and electrons generated by the discharge, and becomes negatively charged. The charged dust moves toward the dust collecting electrode 6 and is directly attracted to the dust collecting electrode 6.
The dust charged by the discharge is captured and adsorbed by the dust collecting electrode 6, and is deodorized and sterilized by the photodecomposition catalyst substance.

止されるので、安全衛生上も好ましい。(1) As described above, the present invention provides a dust collecting electrode having a filter function in which a photocatalytic substance is supported on a material having conductivity and adsorptivity, and irradiates the dust collecting electrode with ultraviolet rays. Since the ultraviolet lamp is provided, the structure of the device is simple, the number of members is reduced, the device can be made compact, and the dust charged by the discharge is captured and adsorbed by the dust collecting electrode, and deodorizing and sterilizing by the photocatalytic substance. As a new air purifying device, it is possible to purify the indoor air synergistically and efficiently, and therefore, differently from a single-function air purifying device, it is possible to effectively perform a plurality of functions. The effect is extremely large. Ozone generated by the application of a high voltage is adsorbed on the activated carbon fiber and decomposed, thereby preventing ozone from being discharged out of the apparatus.
