Description
Technical Field
The present invention relates to an air purifier.
Background
An air purifier is understood as a device that sucks in polluted air for purification and then discharges the purified air. As an example, the air purifier may include: a blowing device for making external air flow into the interior of the air purifier; and a filter capable of filtering out dust or bacteria, etc. in the air.
In general, an air purifier is configured to purify an indoor space such as a home or an office. According to the related art air cleaner, since the capacity thereof is limited, there is a limitation in cleaning the air of the entire indoor space. Therefore, although air in the periphery of the air purifier can be purified, it is not easy to purify air in a space far from the air purifier.
In order to solve such a problem, efforts are being made to improve the performance of a fan provided in an air cleaner, but the larger the amount of air blown by the fan, the more noise is generated in the fan, and the reliability of the product is reduced. As a result, the user needs to move the air cleaner while cleaning the air in a desired space or to install a plurality of air cleaners in different spaces due to the limited capacity of the air cleaner, thereby achieving the purpose of increasing the air cleaning capacity.
In connection with the prior art air cleaner, the applicant has disclosed the following prior patents.
1. Korean patent publication No. (publication date): KR10-2012-0071992 (7/3/2012)
2. The invention has the following name: air purifier

The air suction ports are formed in the side and lower portions of the main body of the air cleaner, and the air discharge ports are formed in the upper portion of the main body.
According to such a configuration, since the contaminated air is sucked from a limited direction, that is, from the side and the lower side with respect to the air cleaner, there is a problem that the suction capacity is reduced. In addition, the corner portions of the rectangular parallelepiped case will act as structural obstacles that hinder the intake of air.
Further, the air purified inside the air purifier is discharged upward in only one direction, so that the air around the air purifier can be purified, but the purified air cannot flow to a space far from the air purifier, and there is a problem in that the air cleaning performance is limited.
In addition, there is a problem in that only one blowing fan is provided inside the body of the air cleaner, and blowing capacity is limited.

Fig. 25 to 27 are diagrams illustrating a flow of air in the air purifier of the embodiment of the present invention. The flow of air in the embodiment of the present invention will be briefly described with reference to fig. 25 to 27.
First, the flow of air by the driving of the first air blowing device 100 will be described. When the first fan 160 is driven, indoor air is sucked into the first casing 101 through the first suction unit 102 and the base suction unit 103. The sucked air passes through the first filter member 120 and impurities in the air can be filtered in the process.
The air passing through the first filter member 120 flows toward a radially upper side during passing through the first fan 160, and a stable upward flow is achieved during passing through the first and second air guides 170 and 180. The air passing through the first and second air guides 170 and 180 passes through the first discharge guide 190 and flows upward through the first discharge portion 105.
The air discharged through the first discharge portion 105 is guided by the partition plate 430 positioned above the first discharge guide 190 and discharged to the outside of the air cleaner 10.
When the second fan 260 is driven, the indoor air is sucked into the second casing 201 through the second suction portion 202. The sucked air passes through the second filter member 220, and impurities in the air can be filtered in the process.
The air passing through the second filter member 220 flows upward in the radial direction while passing through the second fan 160, and flows upward stably while passing through the third air guide 270 and the second discharge guide 280. The air passing through the third air guide 270 and the second discharge guide 280 passes through the flow control device 300 and can be discharged through the second discharge portion 305.
At this time, when the flow control device 300 is located at the first horizontal position as shown in fig. 25 and 26, the air discharged from the flow control device 300 flows upward. On the other hand, when the flow adjustment device 300 is in the second position of being erected as shown in fig. 27, the air discharged from the flow adjustment device 300 can flow toward the front upper side. With the flow regulating device 300, the air volume of the air discharged in the air purifier 10 can be increased, so that the purified air can be supplied to a position far from the air purifier 10.
