As shown in FIG. 6 , the filter device 140 is mounted on the filter mounting portion 138 . The filtering device 140 is composed of a multifunctional filter assembly 142 and a filter frame 144 for inserting the filter assembly 142 .

The filter frame 144 is formed with a filter insertion part 144' for installing and fixing the inserted filter assembly 142, and the size of the filter insertion part 144' corresponds to the shape of the filter assembly 142. In order to easily install the filter frame 144 to the rear frame 130, a handle 144" is formed on the filter frame 144.

Above-mentioned filter assembly 142 is rectangular, and is located on the filter insertion part 144 ', and filter assembly 142 is made up of a plurality of filters, plays the effect (as dust, bacteria, antibacterial, etc.).

Referring to FIG. 7, the above-mentioned filter assembly 142 will be described in detail. The primary filter 142a formed on the front part of the filter assembly 142 mainly filters relatively large dust contained in the air, and the mesh surface of the primary filter 142a has larger holes than other filter mesh surfaces. Other parts with antibacterial effect can also be arranged on the mesh surface.

A high-efficiency particulate air filter 142b is formed on the rear side of the primary filter 142a to filter the air after passing through the primary filter 142a. The HEPA filter 142b is green tea tannin coated. The high-efficiency particulate air filter 142b has a high antibacterial effect, and can filter more than 99.97% of tiny dust of 0.3 microns.

The rear side of the above-mentioned high-efficiency particulate air filter 142b is formed with a deodorizing filter 142C for filtering peculiar smells in the air. The deodorizing filter 142C mainly adopts an activated carbon filter with strong adsorption force, which can remove the smell of smoke and food in the air.

The rear side of the above-mentioned deodorizing filter 142C is also formed with a carbon nano ball (CNB) filter 142d with a better filtering and deodorizing effect than the deodorizing filter 142C.

Carbon Nanosphere (CNB) is composed of 200nm to 500nm spherical shape, and has many small holes formed on the surface, so it has a large adsorption area. The so-called large adsorption area means that the ability to absorb odors is very high.

The carbon nanospheres (CNB) used in the carbon nanosphere (CNB) filter 142d are produced by a 7-stage synthesis method of silicon dioxide, and the size of the carbon nanospheres and the size of pores on the surface of the carbon nanospheres can be adjusted.

Moreover, a catalyst for decomposing odorous objects can be added to the carbon structure of the carbon nanosphere (CNB) filter 142d to increase the decomposition speed of odorous objects, so that two functions of decomposition and adsorption can be performed simultaneously. The carbon nano ball (CNB) filter 142d improves the deodorization ability by 8 times to 12 times compared with the previous activated carbon, and the adsorption capacity improves more than 15 times than the previous activated carbon.

An ozone filter 142e for removing ozone is formed on the rear side of the carbon nano ball (CNB) filter 142d. The function of the ozone filter 142e is to remove the ozone in the air, especially remove the ozone generated by the oxygen generator 176, prevent the ozone from entering the room, and provide people with a more comfortable air environment.

A nano-silver filter 142f is formed on the rear side of the ozone filter 142e. The nano-silver filter 142f is formed by plating metal silver with very good antibacterial and bactericidal properties on the filter, which can effectively prevent bacteria from multiplying.

When manufacturing the nano-silver filter 142f, silver-plating is performed on the resin net or nano-silver is added to the resin net.

An air filter 146 is further provided in front of the filter assembly 142 . The air filter 146 pre-filters the air passing through the filter assembly 142 in front of the filter assembly 142 . The air filter 146 generally uses a primary filter. Primary filter 142a may not be installed on filter assembly 142

On the front frame 120 is formed a discharge port opening and closing device 200 which moves the side discharge blade 124 and opens and closes the side discharge port 122 .

The action of the air cleaner of the present invention having the above-mentioned structure will be described below.

When the air cleaner 100 of the present invention was in operation, the side discharge blades 124 and the bottom surface discharge blades 128 opened the side discharge ports 122 and the bottom discharge ports 126, and the fan (not shown) of the air cleaner 100 passed through the frame 130 formed on the back. The suction grill 132 sucks indoor air into the air cleaner 100 .

Air drawn into the air cleaner 100 first passes through the air filter 146 and then passes through the filter assembly 142 . At this time, the filter assembly 142 is composed of a plurality of filters, and has multiple functions, and can filter dust and peculiar smell contained in the air.

The primary filter 142a of the filter assembly 142 filters relatively large dust contained in the air for the first time, and more than 99.97% of the tiny dust passing through the primary filter 142a is filtered by the high-efficiency particulate air filter 142b.

The air passing through the high-efficiency particulate air filter 142b is then filtered by a deodorizing filter 142c and a carbon nanoball (CNB) filter 142d to filter out odors contained in the air.

The above-mentioned ozone filter 142e filters the ozone produced on the oxygen generator 176, and the nano-silver filter 142f can prevent the breeding of bacteria on the filter. In addition, the ozone generated on the oxygen generator 176 is dispersed into the suction air through the above-mentioned suction grill 132 , and such ozone can kill bacteria contained in the air and bacteria on the filter assembly 142 .

The purified air passing through the filter unit 142 is discharged indoors through the side outlet 122 and the bottom outlet 126 by the fan.

The side discharge blades 124 and bottom discharge blades 128 that open and close the side discharge ports 122 and bottom discharge ports 126 operate independently, so the side discharge blades 124 and bottom discharge blades 128 are selectively controlled according to the user's wishes. Can open side discharge blade 124 and bottom surface discharge blade 128 when indoor polluted air is arranged, can close bottom surface discharge port 126 open side discharge blade 124 when sleeping.

When using the air cleaner 100 for a long time and need to clean or replace the filter assembly 142, hold the handle 144 formed on the filter frame 144 and pull it downward to separate the filter device 140 from the rear frame 130. In the present invention The middle filter assembly 142 is composed of multiple filters, so it is easy to clean or replace the multiple filters. The operation of installing the filter assembly 142 is opposite to the operation of separating the filter assembly 142 .

Moreover, the after-sales service of the air purifier 100 of the present invention is relatively easy to realize. As long as the front panel 110 is disassembled, most of the components in the air cleaner 100 can be seen. Such as control window 154, display unit 150, image display unit 152, etc. Therefore, as long as the front panel 110 is disassembled, it is very easy to repair the minor malfunction of the air cleaner 100 .

The opening and closing of the side discharge vane 124 is controlled by the discharge port opening and closing device 200 .

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still belong to within the scope of the technical solutions of the present invention.
