Abstract
Abstract An ionizer is provided with an ion-producing means in the form of a carbon electrode to which a high source of DC potential is applied for generating a substantial amount of ions of the same polarity as that of the applied potential by corona discharge. In an illustrated application, the carbon ion-producing electrode is mounted on a fan of an air ionizer for rotation therewith, for simultaneously generating air ions and rapidly dispensing the ions in the air stream of the fan, which may be directed axially or radially therefrom.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
An air ionizer for generating and dispersing ionized air, comprising, in combination, a. a radial fan having a fan shaft, b. a rotating cage-type fan blade means mounted on said fan shaft for rapidly moving a stream of air in a radial direction therefrom on the rotation of said fan, c. ion-producing electrode means mounted on and positioned within said cage type fan blade means in conductive contact with said fan shaft for simultaneously generating air ions and rapidly dispersing said ions by said stream of air into the radial space surrounding said fan, d. a source of high D.C. potential, and e. means for conductively coupling said source of high D.C. potential to said fan shaft thereby applying said source of high D.C. potential to said ion-producing electrode means whereby air ions are generated by said ion-producing electrode means by corona discharge.
Claim 2
Dependent Claim
143 words
An air ionizer for generating and dispersing ionized air, comprising, in combination, a. a radial fan having a fan shaft, b. a rotating cage-type fan blade means mounted on said fan shaft for rapidly moving a stream of air in a radial direction therefrom on the rotation of said fan, c. ion-producing electrode means mounted on and positioned within said cage type fan blade means in conductive contact with said fan shaft for simultaneously generating air ions and rapidly dispersing said ions by said stream of air into the radial space surrounding said fan, d. a source of high D.C. potential, and e. means for conductively coupling said source of high D.C. potential to said fan shaft thereby applying said source of high D.C. potential to said ion-producing electrode means whereby air ions are generated by said ion-producing electrode means by corona discharge.
