The present invention relates to an air purifier that cleans contaminated air and converts it into fresh air in homes and offices. In particular, in a filter assembly configured to remove dust through several steps, a pre-collecting and removing air dust is primarily collected. Improved airtightness and function of the filter to improve the inherent functionality of the remaining filter assemblies, extending the function and life of the entire filter assembly, and at the same time, the exchangeability and replacement time of the prefilter can be seen at a glance. It relates to an air cleaner that provides.

In addition, the present invention in the configuration of the filter assembly by arranging the pre-filter from the top of the tower body to maximize the separation of the air inlet and the outlet for discharging the purified air to eliminate the eddy phenomenon and to circulate the flow of indoor air substantially The present invention relates to an air purifier capable of achieving an air cleaning circulation.

LG Electronics (model name: Whissen LA-S060DW), Sharp Electronics (model name: FU-650K), Cheongpung (model name: Mugu CAP-G2705), and Samsung Electronics (model name: Hauzen HC-J130RWP) are box-shaped. Air formed in the upper part of the main body or the upper rear of the main body by removing dust in the air by passing through the filter assembly configured to remove the dust through the air inlet formed in the front of the box-shaped main body formed through the various steps Purify the air by exhausting the purified air through the outlet.

The filter assembly may be, for example, a prefilter that first collects dust in the air and removes relatively large dust, a hepa filter positioned after the prefilter to collect relatively small dust, and ionizes fine dust by electrical action. It may be composed of an electrostatic precipitating filter to collect and a carbon adsorption filter to remove ozone and various odors as necessary.

As described above, commercially available box-type air cleaners include air containing dust in the air, and are sucked through the suction grill formed on the front panel to pass the filter assembly to purify the air step by step. The purified air is discharged through the discharge grille formed at the top or the rear of the main body.

As described above, in the case of the air cleaner that sucks air from the suction grill of the front panel and discharges the air to the discharge grill formed at the top or the rear, the air is discharged in the opposite direction to the circulation convection in the room. When the air discharged to the air purifier discharge grill is blocked, the air is pushed toward the inlet grill again, which causes a kind of eddy phenomenon to continuously filter only the air around the air cleaner without evenly filtering the air in the room.

In this case, the efficiency of the air cleaner drops sharply, and in reality, various harmful substances are exposed to the user, and the meaning of the use of the air cleaner is faded.

On the other hand, in the case of the conventional air cleaner constructed and operated as described above, in order to clean or replace the prefilter, it is necessary to remove the prefilter by removing the prefilter from being assembled with the filter assembly and then cleaning or replacing the prefilter. It is uncomfortable and difficult to clean.

In addition, as the prefilter is separated from the front panel and assembled together with the filter assembly disposed in the main body, airtightness between the respective filters is degraded, thereby causing a problem of shortening the inherent functionality and life of the filter.

In other words, the prefilter collects and removes dust of relatively large particles of about 95% or more of the total amount of dust in the air, and in the next step, filters having intrinsic functions such as hepa filter, electrostatic filter, and carbon adsorption filter are removed from the air. Filtering the dust or odor contained in stages, the body constituting the prefilter must be closely adhered to the rest of the filter to maintain airtightness to ensure that the prefilter performs its own function, that is, large particles Dust can be reliably collected. The body of the prefilter is placed in an environment in which some large particles of dust can enter the remaining filters due to the problem of body appearance and airtightness of other filter assemblies. It not only degrades the function of each filter but also provides a cause of shortening the life of each filter.

In addition, in order to confirm the cleaning or replacement time of the prefilter, it is necessary to open and check the front panel one by one, which is inconvenient to use and neglects it, resulting in a decrease in the functionality and life of the air cleaner.

On the other hand, although the user can check the cleaning or replacement time as the dust display lamp through the conventional dust display device already invented in the air cleaner, there is a problem that increases the product cost due to the adoption of such a device.

The present invention was conceived in view of the problems of the prior art as described above, and the main object of the present invention is to construct a filter assembly to assemble a pre-filter which collects and removes dust in the air as a primary from the remaining filter assembly. It is to provide an air cleaner that facilitates replacement of the prefilter.

In addition, the present invention by assembling the pre-filter separately from the filter assembly, and at the same time it is possible to grasp the replacement time of the pre-filter at a glance so that users can easily identify and access the replacement time with ease of use at a low cost It is to provide an air cleaner to ensure the efficiency of the air cleaner by inducing the appropriate replacement time.

In addition, the present invention is to provide an air cleaner that can improve the inherent functionality of the remaining filter assembly including the pre-filter by improving the airtightness of the pre-filter to improve the function of the filter assembly and to extend its life.

In addition, the present invention by placing the pre-filter on the top of the tower body to maximize the separation of the air inlet and the outlet to discharge the purified air to eliminate the eddy phenomenon and to achieve a practical and effective air cleaning circulation by circulating the natural air flow naturally It is to provide an air purifier that allows.
