B01J019/08

US Classification:

42218607, 42218604, 42218613, 4221863

Abstract:

An electro-kinetic air conditioner for removing particulates from the air creates an airflow using no moving parts. The airflow is subjected to UV radiation from a germicidal lamp within the device. The conditioner includes an ion generator that has an electrode assembly including a first array of emitter electrodes, a second array of collector electrodes, and a high voltage generator. The device can also include a third or leading or focus electrode located upstream of the first array of emitter electrodes, and/or a trailing electrode located downstream of the second array of collector electrodes, and/or an interstitial electrode located between collector electrodes, and/or an enhanced emitter electrode with an enhanced length in order to increase emissivity.

Assignee:

Sharper Image Corporation - San Francisco CA

International Classification:

B03C 3/74

US Classification:

96 29, 96 39, 96 40, 96 51, 96 94, 96 96

Abstract:

An electro-kinetic electro-static air conditioner with a bead member having a bore, through which a wire-like electrode passes. The bead is moved along the wire to frictionally clean the wire-like electrode when an electrode array is removed. A bead lifting arm is mounted to the electrode array. The bead lifting arm can move the bead to clean the electrode as the electrode array is removed from the air conditioner for cleaning. The electro-kinetic electro-static air conditioner has insulated parts which protect against high voltage arcing and conductive deposits relative to the electrodes.

US Classification:

96 25, 95 81, 96 63, 96 80, 361226, 361235

Abstract:

The present invention provides an air treatment device including a housing, an emitter electrode configured within the housing and a collector electrode configured within the housing and positioned downstream from the emitter electrode. The device preferably increases the ions produced for a start up period after the device is initially turned on, wherein the device automatically decreases ion production after the desired period. The device preferably includes a first and second voltage source to selectively increase and decrease voltages applied to the emitter and/or collector electrode to adjust the ion production. In one embodiment, the device includes a voltage controller to selectively adjust the voltage provided by the voltage source for the start up period and normal operation.

US Classification:

42218604, 422121, 96 96

Abstract:

Embodiments of the present invention are related to air conditioner systems and methods. In accordance with one embodiment of the present invention, a system includes at least one emitter electrode and at least one collector electrode that is downstream from the emitter electrode. The emitter electrode has a plurality of pins axially arranged about a center. Preferably, the pins are arranged in a circle about the center. A driver electrode is located within the interior of the collector electrode. Preferably, although not necessarily, the driver electrode is insulated. A high voltage source provides a voltage potential to at least one of the emitter electrode and the collector electrode to thereby provide a potential difference therebetween. The embodiments as described herein have some or all of the advantages of increasing the particle collection efficiency, increasing the rate and/or volume of airflow, reducing arcing, and/or reducing the amount of ozone generated.
