Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner, and more particularly to the structure of a dust collecting part and a blowing part.

[0002]

2. Description of the Related Art In a conventional device, a dust collecting electrode, a discharge electrode, a blower, etc. are firmly held by screws on the main body, and the front surface of the dust collecting part is attached to a front cover or a panel. It was screwed to the body.

Further, only the prefilter and the dust collecting filter provided on the rear surface of the dust collecting electrode are detachable.

[0004]

In the above prior art, even if the ventilation passages other than the prefilter and the dust collecting filter are extremely contaminated, the user cannot easily check the performance and the performance is deteriorated for a long time. There are many problems such as that the main body must be removed when it is used for a period or maintenance.

According to the present invention, by making the dust collecting (blowing) unit detachable, it becomes possible to easily clean and wash the dust adhering to the ventilation passages before and after the dust collecting portion. The purpose is to provide an air purifier with good cleaning and cleaning properties.

[0006]

In order to achieve the above object, the present invention comprises a prefilter 1, a discharge electrode 4, a dust collecting electrode 3 and an ozone removing filter 5 as shown in FIGS. The dust collecting unit a housed in the same frame 2 is detachably attached from the rear cover 9. In addition, a stopper 14 is attached to the frame 2 for preventing falling, and a blower unit b including the duct 7 and the blower 8 is also detachably attached from the rear cover 9. Also in the blower unit b, a stopper 15 is attached to prevent falling. The dust collecting unit a, the stopper 14 of the blower unit b,
By releasing 15, the dust collecting and blowing unit including the dust collecting unit a and the blower unit b can be easily removed from the rear cover 9, and cleaned and washed. Also,
The pre-filter 1 can be easily removed without removing the dust collecting unit a.

[0007]

With the above-described structure, the present invention can easily remove the dust collecting (blowing) unit consisting of the blower, the duct, the prefilter, the discharge electrode, the dust collecting electrode, and the ozone removing filter without disassembling the product. By cleaning and washing, it is possible to prevent deterioration of the dust collection performance, scattering of the attached dust collection, and odors generated by the attached dust collection.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical sectional view of the air purifier, showing an intake port 12 and an exhaust port 13 on a front cover 11 and a panel 10.
Is provided, and there is a pre-filter 1 which is detachable from the intake port 12 in the ventilation path connecting the intake port 12 and the exhaust port 13, and the pre-filter 1 is made of air-permeable metal. In the rear, a dust collecting electrode 3 and a discharge electrode 4 are provided facing each other, and further, an ozone removing filter 5 for removing ozone generated from the dust collecting electrode 3 and the discharge electrode 4 is provided. The electrode 3, the discharge electrode 4, and the ozone removal filter 5 have a dust collecting unit a mounted on the frame 2. If the same product as the pre-filter 1 is provided on the front side of the ozone removing filter 5, the dust entering the ozone removing filter 5 can be removed. Further on the rear side, there are a cushioning member 6, a duct 7 connecting the blower 8 and the dust collecting unit a, and a blower 8 at the contact portion of the dust collecting unit a. The cushioning member 6 is attached to the duct 7, and the duct 7 is Blower 8
There is a blower unit b attached to the same and configured as one body. From the above, the cleaned air is exhausted from the exhaust port 13. Clean dust collection unit a and blower unit b,
When cleaning, as shown in FIG. 2, by rotating the front cover 11 and unlocking the stoppers 14 and 15, the guides 16 and 17 firmly fixed to the rear cover 9 can be slid and taken out. Further, as shown in FIG. 4, in the dust collecting unit a, the dust collecting electrode 3 can be taken out by cleaning and washing the dust collecting electrode 3 by opening the dust collecting electrode stopper 21. Further, the ozone removing filter removing lid 20 is removed to remove the ozone removing filter 5.
Can be taken out, replaced, or cleaned. Note that FIG. 3 shows a state in which the dust collecting unit a is pulled out by rotating the panel 10. FIG. 5 shows a state in which the panel 10 is rotated to take out the pre-filter 1 from the dust collecting unit a. The pre-filter 1 can be attached / detached by applying a force to the panel 10 side to the pre-filter 1 without removing the dust collecting unit a from the frame 2 forming the dust collecting unit a.

According to this embodiment, the pre-filter 1, the dust collecting unit a, and the blower unit b can be easily removed, and the dust collecting unit a and the blower unit b are cleaned and washed to reduce the dust collecting performance and ventilation. It is possible to prevent scattering of dust adhering to the air passage and odor generated from dust adhering to the ventilation passage.

[0011]

Since the present invention is constructed as described above, it has the following effects. Since the ventilation passage is detachable, it can be cleaned and cleaned, and several dust collection units consisting of a prefilter, discharge electrode, dust collection electrode, and ozone removal filter are held and replaced at regular intervals. This does not prevent continuous operation of the main unit. For short-term cleaning of about 1 month, only the removable prefilter is used, and the dust collecting unit and blower unit are cleaned and cleaned every 2-3 months. From the above, there is an effect of preventing the deterioration of the dust collecting performance, the scattering of the attached dust, and the odor generated from the attached dust.
