Abstract

PURPOSE:To inexpensively constitute an air purifier by constituting a dust collecting filter of a conductive filter impregnated with conductive substance and connecting the same to the negative pole of a DC high voltage power supply. CONSTITUTION:As a dust collecting filter, a conductive filter 15 impregnated with conductive substance is formed. An earth electrode plate 16 is fixed to the conductive filter 15 and connected to the negative pole of a DC high voltage power supply 11. When a blower 10 is rotated, dust particles contained in room air are positively charged to be attracted and collected by the conductive filter 15. By this method, a metal net becomes unnecessary and an air purifier becomes inexpensive.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an air cleaner that charges and attracts dust particles.

[Conventional technology]

FIG. 2 is a longitudinal sectional view showing a conventional air cleaner.

In the figure, (1) is a box body with an inlet (2) and an outlet (3).
A pre-filter (4) is provided at the suction port (2), and a grill (6) is provided at the outlet (3). (6) is a discharge wire made of tungsten wire or the like arranged parallel to the internal pressure of the box (1).

(7) is a negative electrode plate formed of a sheet metal with a thickness of 1 to t6 cm and is placed opposite to the discharge wire (6), and (8) is located behind the discharge wire (6) and the negative electrode plate () (to the right of rjA). ) K arranged dust collection filter.

(9) is a wire mesh placed behind the dust filter (8);
aI is a blower installed between the wire mesh (9) and the air outlet (3), and an is a DC high voltage power supply.

A conventional air purifier is configured as described above, and has a discharge wire (6
) and the negative electrode plate (η), a high DC voltage is applied between them, so corona discharge occurs between them.

When the blower rotates, indoor air is sucked in through the suction port (2) and passes between the discharge wire (6) and the negative electrode plate (7).

At this time, dust particles such as cigarette smoke are positively charged, and are attracted and collected by the dust collection filter (8). In this way, clean air is blown into the room from the outlet (3), and this process is repeated thereafter.

[Problem to be solved by the invention]

In the conventional air purifier as described above, a wire mesh (9) is placed behind the dust collection filter (8) for the purpose of sucking in positively charged compacted dust particles.Secondly, it is expensive. This invention has been made to solve the above problems, and is an air purifier that does not require a wire mesh placed on the dust filter and can be constructed at a low cost. : The purpose is to provide.

[Means of rounding to solve problems]

The air purifier according to the present invention uses a dust collection filter as a conductive filter impregnated with a conductive substance.

This is connected to the negative electrode.

[Effect]

In this invention, since the conductive filter is connected to the negative electrode, the positively charged dust particles are adsorbed to the conductive filter, making the wire mesh unnecessary.
