ものであった。2. Description of the Related Art In recent years, in various enclosed spaces irrespective of offices and homes, an air purifier having a function of removing dust, odor, etc. contained in indoor air in order to make them comfortable active spaces. Vessels are being used. As a configuration of an air purifier, generally, a pre-filter, a discharge unit including a discharge electrode and a counter electrode, a dust collection filter, and a deodorization filter are sequentially arranged in the direction of air blown from outside. . As a cleaning process in the air purifier having the above configuration, after removing relatively large dust present in the air by a pre-filter, the dust charging unit removes the dust present in the air by the pre-filter. After the relatively small dust that cannot be completely charged is charged by corona discharge, the charged dust is captured by Lorentz force with a dust collection filter provided on the downstream side to remove the dust, and then provided further downstream. The deodorization is performed by adsorbing odor components in the air by an adsorbent such as activated carbon incorporated in the deodorizing filter.

者が交換する必要があった。However, when the amount of the odor component adsorbed on the adsorbent in the deodorizing filter reaches a certain level during use of the air purifier, the adsorbent reaches a saturated state, and further adsorbing action cannot be expected. To extend the life of the deodorizing filter, it is conceivable to increase the amount of the adsorbent used. However, this results in an increase in the size of the device and an increase in cost. Therefore, the user has to frequently replace the deodorized filter whose life has expired.

A method of reducing the number of replacements of the deodorizing filter by extending the time until the deodorizing filter reaches the saturated state by efficiently decomposing the components, that is, extending the life of the adsorbent has been adopted. When a method of exciting the catalyst by the action of an active species such as oxygen radicals generated from a discharge portion formed by a pair of electrodes is used as the catalyst excitation means, a conventional air purifier communicates with the downstream side of the discharge portion. A sheet-shaped member having pores is arranged, and a catalyst is arranged on the sheet-shaped member.

るという目的が充分に達成されるものではなかった。However, in the prior art described above, since the discharge portion and the sheet-like member are separated from each other, the distance required for the active species generated in the discharge portion to reach the upper sheet member is long. In addition, since the active species generated by the discharge are taken into the downstream electrode forming the discharge part, the probability that the active species reach the catalyst arranged on the sheet member is low. Therefore, the catalyst is not sufficiently excited, and the decomposition of the odor component by the catalyst is not sufficient for the adsorption of the odor component in the deodorizing filter. Therefore, the purpose of extending the service life of the deodorizing filter and reducing the replacement frequency is sufficient. It was not achieved.

Another object of the present invention is to provide an air purifier that does not require replacement itself.

The air that has passed through the discharge unit passes through the filter unit 6 according to the direction of air flow, but relatively small dust charged in the discharge unit is attracted to the dust filter 4 of the filter unit 6 by Lorentz force and is removed from the air. . That is, the dust removal is performed by the pre-filter 1 and the dust filter 4 of the filter unit 6. Since at least one of a catalyst and an adsorbent is disposed in the upstream electrode 2, the downstream electrode 3, and the filter section 6, the catalyst excited by the active species generated in the discharge section has an odor adsorbed by the adsorbent. The components are decomposed, and the active species themselves react with the odor components to remove the odor components. Here, as a catalyst, ZnO, CuO, FeO, T

Is deodorized by decomposing the adsorbed odor component. Since the active species itself also removes the odor component by reacting with the odor component, more efficient deodorization is performed, and whether the deodorizing filter 5 can be used for a long time,
Alternatively, the replacement of the deodorizing filter 5 itself becomes unnecessary. As the catalyst, ZnO, CuO, FeO, T
