US 5,879,435 A · Electronic air cleaner with germicidal lamp

Abstract

An electronic air cleaner (10) includes a housing (20), a mechanical prefilter (30), an electrostatic precipitator cell (40) and at least one germicidal lamp (50). The electrostatic precipitator cell (40) includes a plurality of collector plates (42) for collecting thereon particulate material from the air stream. The germicidal lamp or lamps (50) are disposed to irradiating the collector plates (42) and any particulate material collected thereon with germicidal light to destroy microbial growth that might occur on the particulate material deposited on the collector plates. Reflectors (60) may be provided in operative association with the germicidal lamp or lamps (50) to concentrate the germicidal light unto the collecting surface of the collector plates (42).

Dependent claims

An air cleaner for removing particulate material that is entrained in an air stream passing therethrough, comprising:

a housing having an air stream inlet, an air stream outlet, and defining a flow passage therebetween;
an electrostatic precipitator cell for removing particulate material from the air stream, said electrostatic precipitator cell including a plurality of collector plates disposed within the flow passage for collecting thereon particulate material from the air stream;
and
at least one germicidal lamp operative to emit germicidal light, said at least one germicidal lamp disposed within said housing axially downstream with respect to the air flow of said collector plates and positioned for irradiating the collector plates with germicidal light at an angle of incidence.
