PURPOSE:To obtain the better effect of deodorization over an extended period of time by absorbing the air in a stool at a specific wind amount by a fan to guide to an ozone generator and generating a specific concentration of ozone to pass to a catalyst. CONSTITUTION:A deodorizer 2 is hung down to the outside edge of a stool seat 1 in the shape of a gallery, an air absorption side (a) is connected to an inlet 4 of the bottom of the stool seat through a ventilation flue 3 in the stool seat 1, and an ozone generator 6, a catalyst 7 and a fan 8 subsequently from the air absorption side (a) are arranged in a ventilation system 5. The ozone generator 6 adjusts a generating concentration in the range of 0.05-2ppm, the catalyst 7 is larger than specific surface area 50m<2>/g, a contact area is 0.01-0.35m<2> per wind amount 1m<3>/hr, and its form is a honeycomb with the number of cells for 100-400 cell/inch<2>. The absorbing capacity of the fan 8 sets a wind amount absorbed from the inside of a stool (B) to 7-35 times amount of the capacity in the stool, and deodorization is continued for a set period of time through a control section 10 by a sensor 9. |
