[0003] In particular, in the case of an air purifier, deodorizing performance is required in addition to the dust collecting performance, and equipment constituted by an antibacterial dust collecting filter and a deodorizing filter occupies most of them.
As a deodorizing means for such devices, a device integrated with a filter using a porous substance such as activated carbon is generally used as a deodorizing agent. However, in such a physical adsorption type filter, the adsorbed odor component is saturated in a relatively short time, and it is necessary to periodically replace the filter in order to maintain the deodorizing performance.

As the optical touch butterfly filter to be used, a filter in which at least titanium oxide is supported on a honeycomb-shaped base material mainly composed of a metal such as inorganic fiber, pulp, ceramic, or aluminum is used. Further, as the ultraviolet light source to be used, a germicidal lamp of a hot-cathode fluorescent tube, a black light, and a cold-cathode fluorescent tube lamp may be mainly used in consideration of miniaturization of equipment and durability of the light source itself. .

In addition, similarly to the dust filter, it is necessary to increase the surface area in the ventilation direction in the same manner as the dust collecting filter in order to reduce the dependence on the ventilation pressure and to obtain the deodorizing performance effective as an air cleaner.

However, in practice, it is difficult to uniformly irradiate ultraviolet light to a photocatalyst filter arranged in a plane, and as shown in FIG. The amount of ultraviolet energy received by the photocatalytic filter surface is extremely lower than that near the ultraviolet light source. Further, when the photocatalyst filter is configured in a honeycomb shape, the amount of ultraviolet energy received on the inner surface of each hole is not uniform because it is blocked by each adjacent honeycomb partition as shown in FIG. It decreases extremely as the number increases.

[0009] In these regions, it is expected that the progress of oxidative decomposition of odor components is delayed and that there is a high possibility that deodorization cannot be performed efficiently as compared with the vicinity where direct light is received. By making the photocatalyst into a honeycomb shape, there is an advantage that the contact area with the odor component can be increased, but on the other hand, the above-mentioned drawbacks occur in the structure relating to the ultraviolet light source.

The air purifier of the present invention is an air purifier having a structure in which a dust collecting filter, a deodorizing filter supporting a photocatalyst, a light source lamp for emitting near-ultraviolet light, and a blower fan are sequentially arranged in the direction of air flow. Since the deodorizing filter is rotatable with respect to the light source lamp, the photocatalytic filter can always rotate and move in the vicinity of the fixed near-infrared light source during operation of the air purifier. It is possible to uniformly irradiate relatively strong ultraviolet energy over the entire region. In the air purifier of the present invention, even when the photocatalyst filter has a honeycomb structure, it is possible to irradiate relatively strong ultraviolet rays to the inner surface of each honeycomb hole over the entire area. Further, it is not necessary to use a plurality of cold cathode fluorescent lamps as light sources, and the lamp length itself can be shortened, leading to energy saving and reduction in manufacturing cost.
