Abstract

PURPOSE:To reduce turbulance of an ionization sphere and to enhance dust collection efficiency by equipping a preliminary charge part which is constituted of a discharge electrode impressed with high voltage, the cover of this discharge electrode and an earthed counter electrode and electrifies dirt in the air, a dust collection filter for collecting dirt and a filter for attracting and relaxing odor. CONSTITUTION:When high voltage is impressed to a discharge electrode 1, corona discharge is caused in the circumference of this discharge electrode 1. Tons having the same polarity as the discharge electrode 1 are generated and the lines of ionization are formed toward a counter electrode 4 and an ionization sphere is formed. When the cover 3 of a discharge electrode is ordinarily provided to the upper part of the discharge electrode 1, the ionization sphere is disturbed and the dust collection is deteriorated by about 10-20%. The lines of ionization are formed toward an electrostatic filter 109 and a deodorization filter 110 which are grounded to the earth by providing an aperture part 2 to the cover 3 of the discharge electrode in the upper part of the discharge electrode 1. Turbulence of the ionization sphere is reduced. When the air incorporating dirt is introduced into the ionization sphere of this preliminary charge part 5, the dirt in this air is easily ionized and more attracted to the electrostatic filter 109. Thereby purification is performed in a short time.

As shown in the figure, dust in the indoor air sucked in from an intake grill 101 is removed from a discharge electrode 102, such as a discharge wire applied to a high voltage, and a grounded wire placed parallel to the air flow. After being ionized in a preliminary charging section 105 consisting of a counter electrode 103 and a discharge electrode cover 104 that prevents the discharge electrode from being easily touched during cleaning, it is placed on the suction side of a blower device 108 consisting of a blade 106° motor 107, etc. Foreign matter in the air is collected when passing through the installed electrostatic filter 109, and this electrostatic filter 10
A deodorizing filter 110 disposed integrally with the deodorizing filter 110 adsorbs and removes bad odors in the passing air, and the purified air is blown into the room from the blowing grill 111 by the blowing device 108. At this time, when the pre-charging section 105 applies a DC high voltage 112 to the discharge electrode 102 as shown in FIG. 4, corona discharge is generated around the discharge electrode 102.
Ions with the same polarity as the discharge electrode 102 are generated on the outer periphery to form an ionized sphere, and the dust in the indoor air that is sucked in attracts these ions and becomes electrically charged. It was configured to collect by Coulomb force.

In 05, since the discharge electrode cover 104 is provided near the discharge electrode 102, the ionization sphere is disturbed by the corona discharge from the discharge electrode 102, and as a result, the rate at which particles are charged is reduced, and the electrostatic filter 109 is reliably charged. The problem was that they had a low ability to be captured.

When a high voltage is applied to the discharge electrode 1 in the above configuration, a corona discharge is generated around the discharge electrode 1, ions having the same polarity as the discharge electrode 1 are generated, and an ionization line is formed toward the counter electrode 4-, which causes ionization. A category is formed. At this time, if the discharge electrode cover 3 is normally provided above the discharge electrode 1, the ionization sphere will be disturbed and the dust collection efficiency will be reduced by about 10 to 20%. By providing section 2, ionization lines are also formed toward the grounded electrostatic filter 109 and deodorizing filter 110, thereby reducing turbulence in the ionization sphere, and dust-laden air is transferred to this reserve. When dust in the air enters the ionization zone of the charging section 5, it becomes more likely to be ionized (and is more likely to be adsorbed to the electrostatic filter 109, and the dust collection efficiency will be 10 to 15% compared to when there is no opening 2).
%improves. Further, the air from which dust has been removed is further deodorized by a deodorizing filter 110 to purify the air.

Effects of the Invention As is clear from the above embodiments, according to the present invention, since the discharge electrode cover is provided with an opening above the discharge electrode, disturbances in the ionization sphere are reduced and dust is sufficiently ionized. It is possible to provide an air purifier that can perform purification in a short time because the dust collection efficiency can be increased.
