Description

  The present invention relates to an air cleaner.

  An air purifier is understood as a device that inhales and purifies contaminated air and then discharges the purified air. As an example, the air cleaner may include a blower for allowing outside air to flow into the air cleaner, and a filter capable of filtering dust, bacteria, and the like in the air.

  Generally, an air cleaner is configured to purify indoor spaces such as homes and office rooms. According to the conventional air cleaner, there is a problem that its capacity is limited and purification of the air in the entire indoor space is limited. Therefore, while the air around the air cleaner can be purified, there is a problem that it is difficult to purify the air in a space far from the air cleaner.

  In order to solve this problem, there has been an effort to improve the performance of the fan installed in the air purifier. However, the larger the fan's air flow, the greater the noise generated from the fan, and the lower the reliability of the product. There was a problem to do.

  Eventually, due to the limited capacity of the air cleaner, the user has had the inconvenience of having to purify the air in the desired space while moving the air cleaner.

On the other hand, in the state shown in FIG. 15, the housing main bodies 311 and 312 of the flow control device 300 are in a horizontal position, that is, the top of the housing main bodies 311 and 312 is at a height corresponding to the upper part of the housing case 310a. A certain position can be referred to as a “first position”.

  When the second gear motor 367 is driven, the rotation guide member 370 may move in the vertical direction by the interlocking of the second gear 365 and the second rack 374.

  In addition, since the flow control device 300 can perform the rotation in the first direction, air can be discharged to both front sides of the air cleaner 10, and thereby airflow toward a relatively large indoor space. Is provided.

  Depending on the operation mode of the air cleaner 10, the flow control device 300 can selectively act.

  When the air cleaner 10 is operated in the general operation mode (first operation mode), as shown in FIGS. 1 and 15, the flow control device 300 is in the lying first position. . And the said 1st and 2nd air blowers 100 and 200 can drive, and can form many independent airflows.

  That is, when the first air blower 100 is driven, air is sucked through the first suction portion 102 and the base suction portion 103, passes through the first filter member 120 and the first fan 160, and the first suction device 102. It can be discharged through the discharge unit 105.

  When the second blower 200 is driven, air is sucked through the second suction part 202, passes through the second filter member 220 and the second fan 260, and passes through the third fan 330. You can go through. Then, the ink can be discharged upward through the second discharge unit 305. At this time, the third fan 330 may be turned off.

  22 to 24 are views showing a state of air flow in the air cleaner according to the first embodiment of the present invention.

  First, the flow of air by driving the first blower 100 will be described. When the first fan 160 is driven, room air is sucked into the first case 101 via the first suction portion 102 and the base suction portion 103. The sucked air passes through the first filter member 120, and foreign substances in the air can be filtered in this process. In the process of air passing through the first filter member 120, the air flows in the radial direction of the first filter member 120, is filtered, 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 stable upward flow is performed 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, 180 flows upward through the first discharge part 105 via the first discharge guide device 190. The air discharged through the first discharge unit 105 is guided by a blocking wall 430 located on the upper side of the first discharge guide device 190 and discharged to the outside of the air cleaner 10.

  On the other hand, when the second fan 260 is driven, room air is sucked into the second case 201 through the second suction part 202. The sucked air passes through the second filter member 220, and foreign substances in the air can be filtered in this process. In the course of the air passing through the second filter member 220, the air flows in an upward direction after being sucked and filtered in the radial direction of the second filter member 220.

  The air that has passed through the second filter member 220 flows upward in the radial direction while passing through the second fan 260, and stably flows upward while passing through the third air guide device 270 and the second discharge guide device 280. Is called. The air that has passed through the third air guide device 270 and the second discharge guide device 280 can be discharged through the second discharge unit 305 via the flow control device 300.

  On the other hand, when the flow control device 300 is in the second position, the air discharged from the flow control device 300 can flow toward the front upper side. The flow control device 300 has an advantage that the air volume of the air discharged from the air cleaner 10 is increased, and purified air can be supplied to a position far away from the air cleaner 10.

  Specifically, when the third fan 330 of the flow control device 300 is driven, at least part of the air discharged from the second discharge guide device 280 may flow into the third fan housing 310. The inflowing air may pass through the third fan 330 and be discharged to the outside through the second discharge unit 305.

  Meanwhile, the flow control device 300 can be rotated in the left-right direction by the first guide mechanism while being in the second position. As an example, when the flow control device 300 goes to the upper front side, the air discharged through the second discharge unit 305 can flow to the upper front side. On the other hand, when the flow control device 300 goes to the upper rear side, the air discharged through the second discharge part 305 can flow to the upper rear side.

  According to such an action, since the air discharged from the air cleaner 10 does not simply go upward, it can go forward, so that an air flow toward a space relatively far from the air cleaner 10 is generated. Can be generated. In addition, since the flow control device 300 includes the third fan 330, the air blowing force of the discharged air can be increased.
