The first discharge main body 191 includes a plurality of discharge grills 195 forming the first discharge part 105. The inner wall 191b of the main body of the first discharge body 191 may be disposed to contact the outer surface of the curved portion 444a.

The first discharge body 191 further includes a bending support part 197 provided along an edge of the first discharge body 191. The bent support 197 may be provided between the plurality of discharge grills 195. The bent support 197 may be disposed between two adjacent discharge grills 195 among the plurality of discharge grills 195. The bending support 197 may be provided in plurality.

In the space where the first extension portion 186a and the bent support portion 197 are vertically aligned, discharge of air is blocked. In summary, the first discharge part 105 is understood as an internal space formed by the main body inner wall 191b of the first discharge body 191, the two closest discharge grills 195 and the bent support part 197. Can be. The first discharge part 105 may be provided in plural numbers.

The grill support 196 may be disposed between one discharge grill and another discharge grill among the plurality of discharge grills 195. The grill support 196 may be provided in a number corresponding to the number of the wallpaper paper units 187. For example, as described above, when four wallpaper paper units 187 are provided, four grill support units 196 may also be provided.

In the space where the wallpaper paper portion 187 and the grill support portion 196 are provided, a discharge passage of air, that is, the first discharge portion 105 will not be formed.

The radially outermost portion of the partition plate 430 is located outside the radially outermost portion of the first discharge portion 105. That is, when defining the first virtual line l1 extending in the up-down direction in the radially outermost part of the first discharge part 105, the first virtual line l1 is the partition plate 430. Will pass through.

When defining a second virtual line l2 extending in an up-down direction of the outer circumferential surface of the second guide wall 182 of the second air guide device 180, the second virtual line l2 is defined as the second virtual line l2. 1 The innermost part of the discharge part 105 passes. Therefore, the distance w1 between the first virtual line l1 and the second virtual line l2 may represent the width of the first discharge part 105.

On the other hand, when defining the third virtual line (L3) that extends the outer circumferential surface of the second extension portion 186b in the vertical direction, the third virtual line (L3) is the end of the partition plate 430 ( 443a, 451a.

The distance w2 between the second virtual line l2 and the third virtual line l3 may represent a radial width of the first extension part 186a or the bending support part 197. . The radial width of the partition plate 430 may correspond to the sum of the width w1 of the first discharge part 105 and the width w2 of the first extension part 186a.

In summary, the main body inner wall 191b of the first discharge body 191 is disposed to contact the curved portion 444a of the partition plate 430, and the innermost portion of the first discharge portion 105 is the curved surface. It may be understood that it is disposed at a position corresponding to the portion 444a. The radial width w1 + w2 of the partition plate 430 is larger than the width w1 of the first discharge part 105 by the width w2 of the first extension part 186a. do.

Accordingly, the partition plate 430 is formed to be long enough to completely cover the upper side of the first discharge part 105, and the outermost part of the partition plate 430 is larger than the outermost part of the first discharge part 105. Since it is located outside, the air discharged through the first discharge unit 105 may be prevented from flowing into the second blower 200 through the partition plate 430, that is, the air blow phenomenon.

Explain from a different perspective.

When defining the radial center line Co of the air cleaner 10, the distance S1 from the center line Co to the outermost part of the partition plate 430 is formed in the first discharge guide device 190. It is formed larger than the distance (S2) to the outermost portion of the discharge passage or the second air passage 185 to be. The center line Co may constitute a center line of the first blower 100 or a center line of the second blower 200. As described above, the discharge passage may be understood as a passage extending from the second air passage 185 to the first discharge portion 105.

The first end 443a and the second end 451a are disposed at the outermost part of the partition plate 430, and the first guide wall 181 is disposed at the outermost part of the discharge passage. That is, the distance S1 is a distance from the center line Co to the first and second ends 443a and 451a, and the distance S2 is the first guide wall 181 from the center line Co. It can be understood as the distance to.

According to such a configuration, since the partition plate 430 is formed to be long enough to completely cover the outer portion of the discharge flow path while being disposed above the discharge flow path, the air discharged from the discharge flow path is divided into the partition plate 430. Guided by) may be discharged in the radial direction and the suction phenomenon to the second blower 200 past the partition plate 430 may be limited.

The first extension part 186a of the bent part 186 may support the bent support part 197 of the first discharge guide device 190. In addition, due to the support structure of the first extension part 186a and the bent support part 197, the discharge path of the air can be reduced by the radial width of the bent support part 197, thereby The upper side may be covered by the partition plate 430. As a result, the discharged air may be prevented from being sucked into the second blower 200 beyond the partition plate 430.

The first radius of curvature R1 of the first plate 440 and the second radius of curvature R2 of the second plate 450 may be formed to have different values among the partition plates 430. The radius of curvature of the first plate 440 may correspond to the radius of curvature of the curved portion 444a. For example, the first radius of curvature R1 may be smaller than the second radius of curvature R2.

This is because the curved portion 444a is somewhat sharply rounded so that the air flowing upwardly through the discharge passage is guided in the radial direction perpendicular to the upward direction, whereas the second plate 450 of the second plate 450 This is because the second plate 450 is slightly rounded so as to allow the user to comfortably insert his hand into the upper space.

14 to 16 are views showing the appearance of air flow in the air purifier according to the embodiment of the present invention. 14 to 16, the flow of air according to an embodiment of the present invention will be briefly described.

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 first case 101 through the first suction part 102 and the base suction part 103. The sucked air passes through the first filter member 120, and foreign substances in the air may be filtered in this process. In the process of passing the air through the first filter member 120, the air is sucked in the radial direction of the first filter member 120 and filtered, and then flows upward.

Air passing through the first filter member 120 flows radially upward while passing through the first fan 160, and stable upward flow is achieved while passing through the first and second air guide devices 170 and 180. The air passing 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 part 105.

The air discharged through the first discharge unit 105 is guided by a partition plate 430 located above the first discharge guide device 190 and discharged to the outside of the air cleaner 10. In particular, the air flowing upward may be diverted 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.

In this case, since the radially outermost part of the partition plate 430 is located outside the outermost part of the air flow path discharged through the first discharge part 105, the discharge plate is discharged from the first discharge part 105. It is restricted that the made air flows upward, and can effectively guide the discharge in the radial direction.

On the other hand, when the second fan 260 is driven, the 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 foreign matters in the air may be filtered in this process. In the process of passing the air through the second filter member 220, the air is sucked in the radial direction of the first filter member 120 and filtered, and then flows upward.

Air passing 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. Upstream is achieved. The air passing through the third air guide device 270 and the second discharge guide device 280 may be discharged through the second discharge part 305 via the flow switching device 300.

At this time, if the flow switching device 300 is in the first position lying as shown in Figs. 14 and 15, the air discharged from the flow switching device 300 flows upward. On the other hand, when the flow switching device 300 is in the second position as shown in Figure 16, the air discharged from the flow switching device 300 may flow toward the front upper side. By the flow switching device 300, the air volume of the air discharged from the air cleaner 10 is increased, the purified air can be supplied to a position far from the air cleaner 10.
