Abstract:
An apparatus for purifying and deodorizing air includes a housing and electrode positioned within the housing and having a plurality of emitter members extending from the electrode. A collector plate is mounted within the housing and has a plurality of holes such that a hole is positioned adjacent a respective emitter member. A high voltage generating source is positioned within the housing for applying a high voltage between the electrode and collector plate. The emitter members are moveable relative to the holes within the collector plate for selecting between: (a) an oxidating mode of operation that enhances ozone production to allow an oxygen to split off therefrom for oxidizing and neutralizing pollutants, and (b) an ionic release mode of operation for enhancing the generation of positive and negative ions such that negative ions attach to pollutants that drop out of the air.
Abstract:
An ozone generating cell includes at least two substantially planar electrodes at a potential difference separated by a dielectric sheet, each producing a corona discharge to convert a proportion of any oxygen present to ozone. The electrodes, when considered in plan, are generally offset with regions of the electrodes overlapping or almost overlapping each other, and regions of both electrodes not overlapping each other. One or both planar electrode may feature extending planar portions of a substantially rectangular ‘U’ shape.
Abstract:
An ozonizer and water purifier equipped with the ozonizer comprising an ozonizing discharge element; an electric circuit for applying a voltage to the ozonizing discharge element so as to produce an ozone-generating discharge; a housing having an opening formed therein for receiving the ozonizing discharge element; a cover which seals the ozonizing discharge element in the housing; and a device for turning off the voltage applied to the ozonizing discharge element when the cover is removed. In another embodiment, at least a part of the cover or housing is transparent so as to enable detection of the discharge state of the ozonizing discharge element. Also disclosed is an ozonizer and a water purifier comprising the ozonizer which includes a discharge element for generating ozone by discharge, wherein ammonium nitrate and other substances adhere to the discharge element upon discharge; and a heat generating element for heating the discharge element to a predetermined temperature which induces scattering of at least ammonium nitrate molecules among those substances adhering to the discharge element.
Abstract:
An electro-kinetic electro-static air conditioner includes a self-contained ion generator that provides electro-kinetically moved air with ions and safe amounts of ozone. The ion generator includes a high voltage pulse generator whose output pulses are coupled between first and second electrode arrays. Preferably the first array comprises one or more wire electrodes spaced staggeringly apart from a second array comprising hollow nullUnull-shaped electrodes. Preferably a ratio between effective area of an electrode in the second array compared to effective area of an electrode in the first array exceeds about 15:1 and preferably is about 20:1. An electric field produced by the high voltage pulses between the arrays produces an electrostatic flow of ionized air containing safe amounts of ozone. A bias electrode, electrically coupled to the second array electrodes, affects net polarity of ions generated. The outflow of ionized air and ozone is thus conditioned.
Abstract:
There is provided a highly efficient and compact ozone generating apparatus in which a very short air gap of about 0.2 mm is formed at high accuracy. Non-discharge portions are dispersed and disposed to cover an entire discharge space, or a spacer is provided to form the non-discharge portion. Further, an elastic body is mounted on a back face of an electrode, thereby enhancing an air gap accuracy of the discharge space.
Abstract:
An ozone generating apparatus is disclosed having an ozone generator cell for producing ozone from oxygen containing air received through air inlets in the apparatus. The ozone generator cell includes a series of generally planar dielectric plates and electrodes arranged in spaced apart and noncontacting relationship for generating a high energy electric field between the electrodes. Hollow insulating tubes having a high dielectric strength are provided to support the dielectric plates along longitudinal edges thereof and further include axial slits in the tubes to support longitudinal edges of the planar electrodes. The dielectric plates and hollow insulating tubes define a series of air passages for passing the oxygen containing air across the electrodes to produce ozone. Ozone produced by the ozone generator cell is discharged through an ozone distributor mounted within the apparatus. A blower is provided to drive air in mixed combination with the ozone discharged from the ozone distributor whereby the mixed air and ozone combination is discharged from the apparatus through an ozone outlet.

A generator cell includes a high voltage assembly having a high voltage electrode, a low voltage assembly having a low voltage electrode, a barrier dielectric between the electrodes defining a discharge region for producing a reactive gas, and a welded seal joining the assemblies to create a permanently sealed chamber between the assemblies including the discharge region. The generator cell may have a gap in the discharge region of 0.005 inch or less. The cells may be modularly combined to form a reactive gas generator system.
Abstract:
A corona discharge ozone generator has an inter-electrode gap established by dielectric spacers that engage gap confronting surfaces and are distributed in the gap so that the electrodes need not be self-supporting. Also, gas flow impedance material, which can include the gap spacers, is distributed in the gap to ensure substantially uniform flow of an oxygen containing gas.

This invention concerns a SiO.sub.2, SiN.sub.x protection film formed by a CVD or PVD gas phase glowing method capable of preventing melting of the matrix ingredients at the surface of a dielectric material in electric discharge of an ozone generator and it relates to a dielectric material used for an ozone generator capable of overcoming the problems for the abrasion of electrode and dielectric material or melting of ions or molecules of during electric discharge, as well as a method of forming a protection film therefor based on the finding that an SiO.sub.2 film or SiN.sub.x film can be formed easily on a surface of a predetermined electric material or, further, on a surface of electrode by processing a specific reaction gas, for example, comprising a crude gas such as SiH.sub.4, SiCl.sub.4, N.sub.2, NH.sub.3 or TEOS or further incorporated with an inert gas or like by means of an atmospheric CVD process such as CVD or heat CVD and, in particular, on the finding that the protection film can be disposed directly to the surface of the dielectric material and the electrode in an ozone generator after the completion of assembling.
