Abstract

Abstract An electronic air cleaner, having therein an electrostatic precipitator, is positioned close to an antenna of a radio receiver. The grounded plate electrodes of the precipitator are provided with a flat portion which lies between the precipitator proper and the antenna, so that electric noise wave generated by the precipitator and directing toward the antenna is blocked by the flat portion.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 184 words
A vehicle having an electric device sensitive to an electric noise wave and an electronic air cleaner for cleaning air in a passenger compartment of said vehicle, said cleaner being positioned close to the sensitive electric device and comprising a first group of grounded plate electrodes which are spaced parallel to each other, each of said grounded plate electrodes extending toward the sensitive electric device such that each space defined between any adjacent two of said grounded plate electrodes faces the sensitive electric device, a second group of electrodes juxtaposed in said first group of grounded plate electrodes such that each of said second group of electrodes is spacedly disposed between the adjacent two of said first group of grounded plate electrodes, and an electric power source connected to both the first and second groups of electrodes for applying therebetween a high electric potential, wherein said first group of grounded plate electrodes have a flat electrically conductive section which is connected to and lies on the extending ends of said first group of grounded plate electrodes to substantially close the entrances of the spaces.
Claim 2
Dependent Claim 184 words
A vehicle having an electric device sensitive to an electric noise wave and an electronic air cleaner for cleaning air in a passenger compartment of said vehicle, said cleaner being positioned close to the sensitive electric device and comprising a first group of grounded plate electrodes which are spaced parallel to each other, each of said grounded plate electrodes extending toward the sensitive electric device such that each space defined between any adjacent two of said grounded plate electrodes faces the sensitive electric device, a second group of electrodes juxtaposed in said first group of grounded plate electrodes such that each of said second group of electrodes is spacedly disposed between the adjacent two of said first group of grounded plate electrodes, and an electric power source connected to both the first and second groups of electrodes for applying therebetween a high electric potential, wherein said first group of grounded plate electrodes have a flat electrically conductive section which is connected to and lies on the extending ends of said first group of grounded plate electrodes to substantially close the entrances of the spaces.
Claim 3
Dependent Claim 35 words
A vehicle as claimed in claim 1, wherein said flat electrically conductive section of said first group of grounded plate electrodes comprises a flange formed on an end of each of said grounded plate electrodes.
Claim 4
Dependent Claim 25 words
A vehicle as claimed in claim 1, wherein said flat electrically conductive section of said first group of grounded plate electrodes is a metal plate.
Claim 5
Dependent Claim 40 words
A vehicle as claimed in claim 3, wherein said metal plate member is integral with two of said first group of grounded plate electrodes, said two being located respectively at both sides of said first group of grounded plate electrodes.
