Description

Air cleaning apparatus {Air cleaning apparatus}

The present invention relates to an air purifier.

An air purifier is understood as a device that sucks 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 inside of the air purifier and a filter capable of filtering dust or bacteria in the air.

In general, an air purifier is configured to purify an indoor space such as a home or office. According to the conventional air purifier, there is a problem in that its capacity is limited, so that it is limited to purify the air of the entire indoor space. Therefore, while the air around the air purifier can be purified, there is a problem in that it is difficult to purify the air in a space far away 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 as the fan blown amount increases, the noise generated from the fan increases, thereby reducing the reliability of the product.

After all, 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 the conventional air purifier, the present applicant has disclosed the following prior literature.

First, the flow of air according to the driving of the first blower 100 will be described. When the first fan 160 is driven, indoor air is sucked into the interior of the first case 101 through the first suction unit 102 and the base suction unit 103 . The sucked air passes through the first filter member 120, and foreign substances in the air may be filtered in this process. And, while the air passes through the first filter member 120 , the air is sucked in and filtered in the radial direction of the first filter member 120 , and then flows upward.

The air that has passed through the first filter member 120 flows upward in the radial direction while passing through the first fan 160 , and a stable upward flow is achieved while passing through the first and second air guide devices 170 and 180 . The air that has passed through the first and second air guide devices 170 and 180 passes through the first discharge guide device 190 and flows upward through the first discharge unit 105 .

The air discharged through the first discharge unit 105 is guided by the partition plate 430 positioned above the first discharge guide device 190 and discharged to the outside of the air cleaner 10 . In particular, the upwardly flowing air may be turned radially outward while flowing along the curved portion 444a and the facing portion 444b provided in the first plate 440 of the partition plate 430 .

At this time, since the radially outermost portion of the partition plate 430 is located more outside than the outermost portion of the air passage discharged through the first discharge portion 105 , the first discharge portion 105 is discharged from the outermost portion. It is possible to limit the air flow in the upward direction, and to effectively guide the discharge in the radial direction.

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

The air that has passed through the second filter member 220 flows upward in the radial direction 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 . An upward flow is achieved. The air that has passed 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 .

At this time, when the flow conversion device 300 is in the first position lying as shown in FIGS. 14 and 15 , the air discharged from the flow conversion device 300 flows upward. On the other hand, when the flow conversion device 300 is in the second position erected as shown in FIG. 16 , the air discharged from the flow conversion device 300 may flow toward the front upper side. By the flow conversion device 300 , the amount of air discharged from the air purifier 10 is increased, and there is an advantage that purified air can be supplied to a location far away from the air purifier 10 .
