PURPOSE:To make it possible to easily supply air including constituents of an offensive small into a deodorizing apparatus and to sufficiently deodrize the air by arranging an ozonizer, an ozone decomposing device and a fan in such an order downstreamly from an upstream portion of a vent passageway in the vent passageway and providing a trap in the vent passageway so as to cause the ozonizer to be positioned in the upper portion of the vent passageway of the ozone decomposing device. CONSTITUTION:An offensive smell of foods disposed on a shelf 14 of a foods storage shed 12 is generally heavier than air, thereby falling downwardly, and the offensive smell enters the deodorizing apparatus 17 through an inlet port 16-1 and is guided to a trap by a first vent passageway 17-1. Then a high voltage is applied to an ozonizer 19 by a high voltage source 18 to generate the ozone which causes the offensive smell to be oxidized and decomposed. Air from which the offensive smell is eliminated by the ozonizer 19 is discharged from the vent passageway through an outlet port 16-2 in the storage room of the foods storage shed 12 by a fan 21 by way of an ozone decomposing device 20 which decomposes surplus ozone into oxygen, and a second vent passageway in such an order. |
