Abstract

PURPOSE:To prevent the lowering of dust collecting capacity by providing a dust collecting filter and an earthed dust collecting electrode to the inner wall surface on the side of an air passage of a front panel. CONSTITUTION:The dust in the air taken in a main body 2 from a suction port 3 is positively ionized by an ionizing part 7 to be guided to the air passage 9 between the dust collecting electrode 8 and dust collecting filter 10 provided on the rear side of a front panel 4. A part of the dust is attracted to the dust collecting electrode 8 during the passage through the air passage 9 and the remainder passes through the dust collecting filter 10 by the sucking action of a blower 1 to be collected. By this constitution, high order dust collecting capacity is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air cleaner that removes dust and the like from the air.

BACKGROUND OF THE INVENTION Conventionally, this type of air cleaner has been constructed as shown in FIGS. 2 and 3. In the figure, a feather.

Air intake ports 106 are provided on the left and right side surfaces of a front spring/v1o4 that constitutes the front surface of a main body 103 that incorporates an air blower 101 including a motor or the like and a dust collection filter 102 on its suction side. An ionization section 108 consisting of a discharge wire 108 to which a high voltage is applied and a grounded counter electrode 107 is provided immediately inside the main body of the intake port 105.
Dust in the air taken into the main body is positively ionized in the ionization section 108 and then collected in the dust filter 102.

Problems to be Solved by the Invention However, with the above-mentioned conventional configuration, it is difficult to secure a large suction area because the intake port 105 is located on the side, especially when making the main body thinner. Therefore, the wind speed through which dust passes through the ionization section 108 increases, resulting in a problem in that the efficiency with which dust is ionized decreases and the dust collection performance decreases.

The present invention is intended to solve these problems, and aims to provide an air cleaner with higher dust collection performance even in a structure in which an air intake port is provided on the air purifier.

Means for Solving the Problems In order to solve this problem, the present invention includes a main body that includes a blower device, and a ventilation path that is attached to the front surface of the main body and whose built-in surface communicates with the suction side of the blower device. a front panel having an air intake port near a side surface; an ionization section provided inside the main body of the air intake port and consisting of a high-voltage electrode and a 'KII' facing the ground; and an ionization section attached to the inner wall surface of the front panel on the side of the ventilation path, This device has a dust collection filter provided on the suction side of the device and a ground dust collection electrode facing across the ventilation path.

Function: With this configuration, dust is collected not only in the dust collection filter but also in the ventilation passage.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIG. In the figure, the front part of a main body 2 containing a built-in air blower 1 consisting of blades, a motor, etc. is subjected to If H'2 by a front spring /L/4 having air intake ports 3 on the left and right sides. Immediately within the main body 2 of the intake port 3, there is provided an ionization section 7 consisting of a discharge wire 6 applied to a positive high voltage and a facing chamber ('fii-6) that is grounded. It has a dust collection electrode 8 which is integrated with the counter electrode 6 of the ionization section 7 and is also grounded.
is the air blower 1 across the ventilation path 9 communicating with the intake port 3.
The dust filter 1o is installed in parallel with the dust filter 1o attached to the suction side of the filter.

According to the above configuration, the dust in the air taken into the main body 2 from the air intake port 3 is positively ionized in the ionization section, and then is passed through the ventilation path between the dust collection electrode 8 and the dust collection filter 10 on the back of the front panel 4. Guided within 9. When passing through this ventilation path 9, a part of the dust adheres to the dust collection electrode 8, and the rest is sucked by the ventilation device 1 to the dust collection filter 10.
Since the dust passes through the dust filter 10, it is collected by the special dust filter 10. Therefore, compared to the conventional case where dust is collected using only a 1° dust collection filter, the front panel 4
Since the dust collection electrode 8 attached to the back also has the function of attaching dust, the dust collection performance can be greatly improved. It compensates for the shortcomings of

In addition, in this explanation, the dust collection electrode 8 on the back of the front spring/L/4
Although the ionization section 70 and the counter electrode 6 are integrated, the same effect can be obtained even if they are separated.

Effects of the Invention As described above, according to the present invention, in addition to collecting dust with the conventional dust collecting filter, dust is also collected with the dust collecting electrode provided on the back of the front panel along the ventilation path. The structure allows air to be taken in from the side of the front panel, resulting in high dust collection performance.
