Description

Air cleaning apparatus {Air cleaning apparatus}

The present invention relates to an air purifier.

An air purifier is understood as a device that takes in polluted air, purifies it, and then discharges the purified air. For example, the air purifier may include a blower for introducing external air into the air purifier and a filter capable of filtering dust or bacteria in the air.

In general, air purifiers are configured to purify an indoor space such as a home or office. According to the conventional air purifier, there is a problem in that the capacity is limited and thus the ability to purify the air in the entire indoor space is limited. Therefore, while the air around the air purifier can be purified, it is difficult to purify the air in a space far from the air purifier.

In order to solve this problem, efforts have been made to improve the performance of the fan provided in the air purifier, but there is a problem in that the reliability of the product deteriorates because the noise generated from the fan increases as the airflow amount of the fan increases.

As a result, due to the limited capacity of the air purifier, the user has the inconvenience of having to purify the air in a desired space while moving the air purifier.

In relation to conventional air purifiers, the present applicant has disclosed the following prior art documents.

The outermost part in the radial direction of the partition plate 430 is positioned more outward than the outermost part in the radial direction of the first discharge part 105 . That is, when defining a first imaginary line ℓ1 extending up and down from the radially outermost part of the first discharge part 105, the first imaginary line ℓ1 extends from the partition plate 430 will pass through

When defining a second imaginary line ℓ2 extending in the vertical direction on the outer circumferential surface of the second guide wall 182 of the second air guide device 180, the second imaginary line ℓ2 is 1 passes through the innermost part of the discharge part 105.

At this time, since the outermost part in the radial direction of the partition plate 430 is located outside the outermost part of the air passage discharged through the first discharge part 105, the discharge from the first discharge part 105 The upward flow of air is limited, and discharge in the radial direction can be effectively guided.

Meanwhile, when the second fan 260 is driven, indoor air is sucked into the second case 201 through the second suction part 202 . Inhaled air passes through the second filter member 220, and in this process, foreign substances in the air may be filtered out. And, while the air passes through the second filter member 220, the air is sucked in the radial direction of the first filter member 120, filtered, and then flows upward.

The air that has passed through the second filter member 220 flows radially upward while passing through the second fan 160, and is stable while passing through the third air guide device 270 and the second discharge guide device 280. upward flow takes place. The air passing through the third air guide device 270 and the second discharge guide device 280 may be discharged through the second discharge unit 305 via the flow conversion device 300 .
