KR-20260065189-A - Eco-friendly fine dust and odor purification devices equipped with wet filters using water absorption and dust adsorption

Abstract

The present invention allows for the removal of indoor fine dust and odors by introducing substances to be purified, such as fine dust and odors remaining indoors, into the body through the inlet hole for substances to be purified, and then exhausting only clean air filtered by a filter body contained within the body into the room. Additionally, since the introduced fine dust and odors are filtered by an absorption adsorption filter, then filtered again by water absorbed by a moisture-retaining filter wrapped around the absorption adsorption filter, and then exhausted into the room, the substances to be purified can be thoroughly purified by the water absorbed by the filter body. Furthermore, because the fine dust introduced through the inlet hole for substances to be purified is filtered once by the absorption adsorption filter by the micro-adsorption bristles provided on the surface of the absorption adsorption filter, filtered a second time by the water absorbed by the absorption adsorption filter, and filtered a third time by the water absorbed by the moisture-retaining filter, only clean air can be exhausted to the room, thereby significantly improving the indoor purification function. Moreover, the moisture-retaining filter and the absorption adsorption filter can be easily and simply washed and reused. An eco-friendly fine dust and odor remover equipped with a wet filter utilizing water absorption and dust adsorption, which allows for economical cost reduction by eliminating the burden of filter replacement costs, is disclosed.

Description

Eco-friendly fine dust and odor purification devices equipped with wet filters using water absorption and dust adsorption The present invention relates to an eco-friendly fine dust and odor remover equipped with a wet filter utilizing water absorption and dust adsorption. More specifically, the invention comprises a water-receiving filter having porosity inside the purification device and an absorption-adsorption filter surrounding the water-receiving filter, which absorbs water and adsorbs dust. This allows for the purification of fine dust and odors by water without forcibly circulating water by a pump, thereby enabling eco-friendly purification of indoor spaces. Furthermore, due to the simple configuration, consumers are not burdened by purchase costs, and the water-receiving filter and absorption-adsorption filter can be easily and simply washed and reused. Additionally, the invention provides an indoor humidity control function. Generally, air purifiers are primarily used to remove fine dust and odors remaining in indoor spaces. As devices that purify contaminated air and transform it into fresh air, most adopt a method of purifying the air by passing air containing pollutants through a filter to remove dust, bacteria, and odors. With the recent increase in air pollutants such as yellow dust, fine dust, and ultrafine dust, there is a growing demand for such air purifiers to purify the air and create a pleasant indoor environment. However, since air purifiers use dry filters to filter out air pollutants, they must be replaced periodically to prevent a decline in purification performance, which inevitably causes inconvenience. Furthermore, because the cost of purchasing dry filters is repeatedly incurred, it not only increases the economic burden on consumers but also leads to a problem where the workability of the filter replacement is reduced, as the external parts of the air purifier must be disassembled to replace the filter located inside the air purifier and then reassembled after replacement. Accordingly, wet air purifiers that use water are being devised so that filter replacement is not required. For example, registered patent No. 10-2067737 describes a water filter air purifier, which comprises a chamber filled with water, an air intake port provided on the side of the chamber through which external air is drawn into the chamber, a flow path connecting the air intake port and the lower part of the chamber, and an air outlet port provided on the upper surface of the chamber through which external air drawn in through the air intake port is discharged to the outside; a main body case comprising an intake fan provided on the upper side of the chamber of the main body case through which external air is drawn into the chamber through the air intake port, and a porous pulverizing means that is submerged in the water of the chamber of the main body case but is provided at least above the flow path, and is made porous so that air bubbles flowing into the chamber through the flow path and passing through the water rise and are pulverized by collision as they pass through the pores. The conventional technology described above filters out contaminants in the external air by driving an intake fan to draw in external air through the air intake port of the main body case, passing it through water contained in the chamber of the main body case to turn it into air bubbles, and then pulverizing the air bubbles as they pass through a porous pulverization means and an auxiliary pulverization means and discharging them through an air outlet. However, as porous pulverization means as well as auxiliary pulverization means must be provided inside the main body case for the pulverization of air, the configuration of the air purifier inevitably becomes complex, and the cost of the air purifier increases, which poses a problem of placing a burden on consumers in terms of purchase costs. As another example, an air purifier using a water filter, registered patent No. 10-2277299, has been devised, which includes a main body having a water storage chamber in which water is stored, an intake port for air intake formed on one side, and an exhaust port for exhausting air from the water storage chamber on the other side; a blower unit installed in the main body to inhale air through the intake port and blow air into the water storage chamber; a blower tube having a buoyancy capable of floating on the water stored in the water storage chamber, with a flow path formed inside through which air blown from the blower unit can pass and a nozzle formed on one side for blowing air passing through the flow path; and a blower tube having buoyancy capable of floating on the water stored in the water storage chamber, wherein the blower tube descends such that at least a portion is submerged in the water stored in the water storage chamber by the pressure of the air blown from the blower unit, thereby blowing the air blown from the blower u
