[0004]

[Problems to be solved by the invention]

 The problem of the present invention is to further improve the cleaning function and to further improve the living environment by combining the above ceramic balls with an indoor air cleaner.

[0005]

[Means for Solving the Problems]

 In the indoor air purifier of this invention, a prefilter, a high-voltage dust collector, an activated carbon filter and a fan are arranged in a line in a substantially rectangular parallelepiped case, and an intake port is provided on the prefilter side of the case. Also, in an indoor air purifier having an outlet on the fan side, a large number of ceramic particles mainly composed of silicon dioxide are dispersed and arranged between the activated carbon filter and the outlet. .

When the above-described indoor air purifier is operated, dirty air in the room enters the indoor air purifier through the intake port as in the related art, and relatively large dust is captured and removed by the pre-filter. The small dust is charged and adsorbed by the dust collector, the air is ionized at the same time, the ozone and odors are removed by the activated carbon filter, and after being cleaned, it is returned to the room from the outlet. When air passes between the activated carbon filter and the outlet, it comes into contact with ceramic particles containing silicon dioxide as a main component, so that dirt, odors, and other harmful components remaining in the air are adsorbed to the ceramic particles. It is believed that the above-mentioned ceramic particles release a kind of resuscitation energy into the air that is effective in activating plants and animals, although the details are unknown. The lifespan of these plants is extended, and the withering plants are revived.

The above-mentioned pre-filter, high-voltage dust collector and activated carbon filter are formed in a rectangular or rectangular parallelepiped shape which is long in a direction perpendicular to the arrangement direction (the direction of air flow) and parallel to each other. The fan is preferably a cylindrical multi-blade fan that is parallel to the fan. In this case, the case is formed to be relatively thin with a small depth, and the installation of the indoor air cleaner becomes easy.

Examples of the silicon dioxide constituting the main component of the ceramic particles include natural quartz, scale stone, cristobalite, and the like. The ceramic particles are preferably made of silicon dioxide to have a diameter of several millimeters. Although it is formed into a sphere, a sphere having a diameter of about 3 mm, which is produced by adding soda ash and lime to the above-mentioned silica sand containing silicon dioxide, and then forming and solidifying it, is preferred. The ceramic particles can be dispersed and arranged between the activated carbon filter and the outlet by any means. For example, an adhesive can be attached to the inner surface of a case that forms a wall surrounding the air passage from the activated carbon filter to the air outlet, or it can be attached to a net stretched over the passage, but air can pass through the air passage. It is preferable to install a cage-shaped container of an arbitrary size capable of performing the above-mentioned process, and to encapsulate a large number of spherical ceramic particles in the cage-shaped container so as to be freely movable.

[0009] In the above-mentioned cage-shaped container, the inside of an elongated tubular body having a length substantially equal to that of the multi-blade fan is partitioned into a plurality of small chambers. It is particularly preferable to form a hole. Preferably, the cage is provided between the edge of the outlet on the leading side with respect to the rotation direction of the multi-blade fan and the multi-blade fan, and the ceramic particles are preferably movably sealed in each of the small chambers. In this case, however, the amount of air passing through the air passage is not reduced, and the air does not cause excessive vibration and noise of the ceramic particles, thereby enabling quiet operation.
