Abstract

PURPOSE: To perform efficiently deodorizing with a small-sized and low consumption electric power and to prevent surely excited light from leaking to the outside by covering the surface of an exciting light source with a photocatalyst when deodorizing is performed by usjng the photocatalyst excited by a light from the exciting light source. CONSTITUTION: In n deodorizing apparatus, a filter 3 is fitted on an intake vent 2a of an air duct 2 passing through a casing 1 and a fan 4 is installed in the neighborhood of an exhaust vent 2b and e.g. three pieces of deodorizing units 5 which approximately intersect the straight pipe-like air flow direction at right angles are placed in the intermediate part. In addition, the light emitting face except both end electrodes of a cylindrical ultraviolet lamp is covered with a photocatalyst. Then, when electric source is supplied to the ultraviolet lamp of each deodorizing unit and the fan is worked under a condition where the photocatalyst is actuated, contaminated air flows into the air duct 2 from the outside through the intake vent 2a and the filter 3 and it is brought into contact with the photocatalyst. At this instance, odor components in the air are absorbed with the excited photocatalyst and the air is exhausted from the exhaust vent 2b.

2. Description of the Related Art Conventionally, a deodorizing device for deodorizing air taken into a device through a filter to deodorize air inside a house or a vehicle is brought into contact with a photocatalyst excited by an excitation light source to deodorize, for example. It is disclosed in JP-A-3-157125 and JP-A-5-293165. Since this photocatalyst has a longer life than an ordinary adsorbent such as activated carbon, maintenance of the deodorizing device becomes easy. In a deodorizing device using such a photocatalyst, the photocatalyst is supported on a honeycomb or the like, and the photocatalyst is excited by an excitation light source such as an ultraviolet lamp installed at a remote place to deodorize a malodorous component.

However, in order to supply light to the photocatalyst carried by the carrier, the carrier and the excitation light source are provided at a position apart from each other to some extent, and the carrier is In the case of a honeycomb structure, etc., the ultraviolet rays radiated to the photocatalyst are not uniform, and there is a portion where the ultraviolet rays do not reach because of the shadow of the carrier itself, so the activation of the photocatalyst becomes insufficient and the desired deodorizing effect. In order to obtain the above, it is necessary to enlarge the carrier to increase the amount of photocatalyst, to increase the irradiation time of ultraviolet rays, or to use high-output ultraviolet rays, which leads to an increase in the size of the device and an increase in power consumption. It becomes a problem. In addition, in the above device, environmentally unfavorable ultraviolet rays may leak to the outside unless the device is completely sealed.
