Description

TECHNICAL FIELD

[0001] The disclosure relates to an air cleaner. BACKGROUND

[0002] An air cleaner is understood as a device that sucks in contaminated air and filters it inside and then discharges the filtered air to the outside. The air cleaner is configured to purify air in an indoor space such as a living room and an office. In general, the air cleaner includes a blower configured to suck in outside air into its inside and discharge the purified air, and a filter provided inside the blower to filter dust or bacteria in the air. In this regard, the air cleaner can further include a flow adjustment device configured to control a discharge direction of the air discharged from the blower. However, because the moving radius of the flow adjustment device is limited, the air can not be discharged in a desired direction.

[0003] A related art (Korean Patent Application Publication No. 10-2017-0101100, hereinafter referred to as related art 1) discloses an air cleaner that further includes a flow adjustment device configured to control a discharge direction of the air discharged from the blower. According to the air cleaner of the related art 1, the air entering the blower is filtered by the filter provided in the inside of the blower and then discharged along a vertical direction perpendicular to an upper surface of the blower. Thereafter, the air discharged from the blower is blown along a direction different from the vertical direction via the flow adjustment device.

[0004] However, even with the air cleaner of the related art 1, the air discharged from the blower is blown only along the vertical direction or along a direction forming a predetermined angle with respect to the upper surface of the blower. The air can not be blown in a horizontal direction parallel to the upper surface.

[0005] Another related art (Korean Patent Application Publication No. 10-2019-0120126, hereinafter referred to as related art 2) discloses an air cleaner that includes a flow adjustment device configured to control a discharge direction of the air discharged from the blower, and a rotation guide unit for causing rotation of the flow adjustment device. According to the air cleaner of the related art 2, the position of the flow adjustment device can vary depending on the degree to which the rotation guide unit is withdrawn. The air discharged from the blower can be blown along other directions different from the vertical direction via the flow adjustment device depending on the degree to which the rotation guide unit is withdrawn.

[0006] However, even if the air cleaner of the prior art 2 is used, a space in which the rotary guide unit is received in the blower is limited. As such, it is not possible to secure the length of the rotary guide unit to change the state to allow the upper surface of the flow adjustment device to be perpendicular to the upper surface of the blower. Therefore, there is a limitation that the air discharged from the blower is difficult to blow in a desired direction. SUMMARY

[0007] Technical problem

[0008] One of the various objects of the present disclosure is to provide an air cleaner capable of discharging filtered air in a horizontal direction parallel to the upper surface of the blower.

[0009] Further, one of the various objects of the present disclosure is to provide an air cleaner including a flow adjustment device that can change the position of the upper surface from a horizontal position parallel to the upper surface of the blower to a direction perpendicular to the upper surface of the blower.

[0022] The outer case includes a first guide rail extending across an outer face of the outer case in a longitudinal direction thereof, and a second guide rail extending across an inner face of the outer case in the longitudinal direction, wherein the first guide rail and the second guide rail are formed in a central region of the longitudinal direction of the outer case, and the first guide rail and the second guide rail are disposed opposite to each other.

[0023] The inner case includes a groove extending across an outer face of the inner case in a longitudinal direction, and an opening passing through a portion of a region of the outer face of the inner case corresponding to the groove, wherein the groove has a recessed shape in the outer face of the inner case.

[0024] The opening is closer to one end of the inner case received in the interior of the outer case than to the other end of the inner case connected to the flow regulating device.

[0025] The guide member further includes a first wheel disposed in the interior of the hair dryer and configured to rotate in engagement with the first guide rail, and a second wheel disposed in the interior of the inner case and configured to rotate in engagement with the second guide rail, wherein the second wheel is closer to one end of the inner case received in the interior of the outer case than to the other end of the inner case connected to the flow regulating device.

[0026] The second wheel is configured to engage with the second guide rail through the opening.

[0027] The second wheel is controlled to rotate until the flow regulating device is oriented to the second position, and is controlled to rotate only after the flow regulating device is oriented in the second position.

[0028] The outer case is controlled to retract into the interior of the hair dryer or to extend from the upper surface of the hair dryer based on a rotational motion of the first wheel, wherein the inner case is controlled to retract into the interior of the outer case or to extend from the other end of the outer case based on a rotational motion of the second wheel.

[0029] The position of the flow regulating device is switched between the first position and the second position based on the rotational motion of the first wheel, wherein the position of the flow regulating device is switched between the second position and a third position based on the rotational motion of the second wheel.

[0032] Beneficial effects

[0033] According to the present disclosure, an air cleaner includes a hair dryer configured to suction air from the outside, filter the suctioned air, and discharge the filtered air, a flow adjustment device disposed above the hair dryer, wherein the flow adjustment device is configured to suction the air discharged from the hair dryer, adjust a discharge direction of the suctioned air, and discharge the air from the same to the outside along the adjusted direction, and a guide member having one end passing through an upper surface of the hair dryer and being received in the hair dryer and the other end connected to the flow adjustment device. The guide member is configured to be retracted into the inside of the hair dryer or to extend from the upper surface of the hair dryer so as to cause a position change of the flow adjustment device. An angle defined between an upper surface of the flow adjustment device and the upper surface of the hair dryer is mainly increased or decreased based on a degree to which the guide member extends from the hair dryer.

[0034] Via the movement of the guide member, the flow adjustment device can be oriented such that the upper surface thereof is perpendicular to the upper surface of the hair dryer. In this way, the air discharged from the hair dryer is discharged to the upper surface of the hair dryer in a horizontal direction by the flow adjustment device.

[0035] The guide member can include an outer shell defining an appearance and an inner shell surrounded by the outer shell. The position of the flow adjustment device can mainly change as the outer shell extends from or is retracted into the hair dryer. Then, the position of the flow adjustment device can additionally change as the inner shell extends from or is retracted into the outer shell.

[0036] In this regard, the guide member can be composed of the outer case and the inner case. In this way, the space occupied by the guide member in the interior of the hair dryer can be reduced. Therefore, it is not necessary to ensure that the length of the guide member is large to change the position of the flow adjustment device so that the upper surface of the flow adjustment device is perpendicular to the upper surface of the hair dryer. Thus, the restriction on the change in the position of the flow adjustment device caused by the restriction on the space of the interior of the hair dryer occupied by the guide member can be eliminated.

The top portion of the side panel 305 and the top portion of the front case 300 can be fastened to each other via fastening between the first hooks 333 and the first counterpart hooks 335. Further, the bottom portion of the side panel 305 can be configured to include a pair of second counterpart hooks 345, which are symmetrical to each other in a horizontal direction. The bottom portion of the front case 300 can be configured to include a pair of second hooks 343, which are respectively disposed at positions corresponding to the second counterpart hooks. The bottom portion of the side panel 305 and the bottom portion of the front case 300 can be fastened to each other via fastening between the second counterpart hooks 345 and the second hooks 343. In one embodiment, the bottom portion of the side panel 305 can be configured to further include a magnet (not shown). The bottom portion of the front case 300 can be configured to further include a magnet counterpart (not shown) made of metal. Coupling between the bottom portion of the side panel 305 and the bottom portion of the front case 300 can be guided via coupling between the magnet and the magnet counterpart.

[0072] Referring to Fig. 3 , the third filter member 350 can be disposed on the seating seat 340 at a boundary between the rear panel 310 and the side panel 305.

[0073] The seating seat 340 can have a protruding shape toward the front case rather than the rear panel, and can be configured to surround an edge of the rear panel 310.

[0074] In an exemplary embodiment, the inner surface of the rear panel 310 and the filter member 350 can be in contact with each other, and can be configured to have the same area as each other.

[0075] Referring to Fig. 4 , the rear case of the flow regulating device 30 can be configured to be detachable when the flow regulating device 30 is oriented in the third position. The filter member 350 can be configured to be detachable from the flow regulating device 30 when the rear case is separated from the front case 300.

[0076] Specifically, in a state where the flow regulating device 30 is oriented in the third position, that is, in a state where the upper surface of the flow regulating device 30 is oriented to be perpendicular to the upper surface of the second blower 20, the fastening between the first hook 333 and the first counterpart hook 335 is released, so that the top of the side panel 305 and the top of the front housing 300 can be separated from each other. Then, since the fastening between the second counterpart hook 345 and the second hook 343 is released, the bottom portion of the side panel 305 and the bottom portion of the upper housing 300 can be separated from each other. In one example, the bottom portion of the side panel 305 and the bottom portion of the upper housing 300 further include a magnet and a magnet counterpart, respectively. In this case, before the fastening between the second counterpart hook 345 and the second hook 343 is released, the fastening between the magnet and the magnet counterpart is released in order to cause the separation between the bottom portion of the side panel 305 and the bottom portion of the upper housing 300.

[0077] In an exemplary embodiment, the first filter member 130 and the second filter member 230 can be composed of the same filter as each other. The third filter 350 can be composed of a different filter from the first filter member 130 and the second filter member 230. In one embodiment, the first filter member 130 and the second filter member 230 can be composed of a HEPA filter, respectively. The third filter member 350 can be embodied as a pre-filter.

[0078] As described above, after the air is filtered by the first filter member 130 and / or the second filter member 230, the air discharged from the blowers 10 and 20 passes through the rear panel 310 of the flow regulating device 30 and is suctioned into the inside of the flow regulating device 30. Foreign substances contained in the air can be further filtered while passing through the third filter member 350 which contacts the inner surface of the rear panel 310. The third blowing fan 360 provided in the inside of the flow regulating device 30 and the discharge grill 320 provided in the front housing 300 of the flow regulating device 30 can blow and discharge the air in which foreign substances are additionally filtered. Accordingly, due to the third filter member 350, the inside of the flow regulating device 30 can have only a small amount of foreign substances, so that a cleaning period of the inside of the flow regulating device 30 can be prolonged.

[0079] In one example, the rear housing, that is, the side panel 305 and the rear panel 310, can be easily separated from the front housing 300 by releasing the first hook fastener and the second hook fastener, respectively. Accordingly, the inside cleaning of the flow regulating device 30 can be effectively performed.

[0080] Further, the rear panel 310 serving as the suction grill 310 to suck in air and the third filter member 350 disposed on the inner surface of the rear panel 310 can be separately washed after the rear case is separated from the front case 300. Accordingly, maintenance of the flow adjustment device 30 can be easily performed.

[0088] Reference Fig. 6 to Fig. 8In a state in which the upper surface of the flow regulating device 30 and the upper surface of the second blower 20 are oriented to be parallel to each other, the flow regulating device 30 and the second blower 20 are spaced apart from each other, so that at least a portion of the air discharged from the second discharge hole 220 flows along the outer side wall of the flow regulating device 30 and is discharged to the outside through the space between the flow regulating device 30 and the second blower 20.

[0089] The flow regulating device 30 can include a rear housing forming an appearance and configured to define a rear face of the flow regulating device 30, and the rear housing includes a suction grille 310 configured to suction air discharged from the blowers 10 and 20. The flow regulating device 30 can include a front housing 300 fastened to the rear housing and configured to define a front face of the flow regulating device 30. The front housing 300 can include a discharge grille 320 configured to discharge air suctioned through the suction grille 310. The flow regulating device 30 can include a blowing fan 360 disposed between the front housing 300 and the front housing 300 and configured to generate an air flow so as to discharge air suctioned through the suction grille 310 through the discharge grille 320. The rear housing includes a rear panel 310 defining a rear face of the flow regulating device 30, and a side panel 305 extending from the rear panel 310 to the front housing 300 so as to define a side face of the flow regulating device 30. The rear panel 310 of the rear housing 300 can be configured to function as the suction grille 310. That is, the combination of the side panel 305 and the rear panel 310 can form the rear housing 300.

[0090] In this regard, a portion of the rear housing other than a portion in which the suction grille 310 is disposed, i.e., a portion in which the side panel 305 is disposed, can be formed as a shield structure so as to restrict movement of air. Accordingly, air discharged from the second discharge hole 220 can be suctioned to the inside of the flow regulating device 30 only through the suction grille 310.

[0091] The rear panel 310 and the side panel 305 can be integrally formed with each other. The side panel 305 and the front housing 300 can be configured to be fastened to each other via, for example, hook fastening.

[0092] The flow regulating device 30 can be oriented in a first position, a second position, and a third position based on the operation of the guide member 40. When the flow regulating device 30 is oriented in the first position, the side wall of the rear housing can be spaced apart from the side wall of the second blower 20.

[0093] In an exemplary embodiment, the side wall of the second blower 20, i.e., the side wall of the second housing 200, can be configured to have a tilt perpendicular to the rear panel 310. The side panel 305 can be configured to have a tilted slope with respect to the rear panel 310.

[0094] In an exemplary embodiment, each of the upper surface and the lower surface of the side panel 305 can be configured to have a circular shape. The circumference of the lower surface of the side panel 305 can be configured to have a smaller size than the circumferential size of the upper surface of the side panel 305.

[0095] In an exemplary embodiment, the outer side wall of the side panel 305 can be configured to have a curved shape. In one embodiment, when the flow adjusting device 30 is oriented in the first position, the outer side wall of the side panel 305 can be configured to extend away from the second discharge hole 220 as the side panel approaches the front housing 300.

[0096] In an exemplary embodiment, when the flow adjusting device 30 is oriented in the first position, the second discharge hole 220 can be configured to be partially covered by the rear grill 310 of the flow adjusting device 30. Accordingly, a portion of the air discharged from the second discharge hole 220 can be discharged to the outside along the outer side wall of the side panel 305. The remaining portion of the air discharged from the second discharge hole 220 can be drawn into the inside of the flow adjusting device 30 through the rear grill 310.

[0097] The second blower 20 is configured to be disposed above the second blowing fan 260 and can further include a guide member seating seat 270 configured to have the guide member 40 seated thereon. The guide member seating seat 270 can be controlled to rotate in a clockwise or counterclockwise direction. Accordingly, the moving direction of the guide member 40 can be freely adjusted in a circumferential direction.

[0098] The second blower 20 can further include a protrusion 280 configured to be disposed in the second discharge hole 220 and configured to increase the flow rate of the air moving along the inner wall of the second housing 200. The protrusion 280 can have a shape protruding in a horizontal direction from the inner wall of the second housing 200.

[0099] In one example, Fig. 6 and Fig. 7Only the structure of the second blower 20 is illustrated and the structure of the first blower 10 is not illustrated. The first blower 10 can also include a protrusion (not illustrated) configured to be disposed in the first discharge hole 120 and configured to increase the flow rate of air moving along the inner wall of the first housing 100. The protrusion included in the first blower 10 can have a shape protruding in a horizontal direction from the inner wall of the first housing 100. When the first blower 10 and the second blower 20 both include a protrusion, the protrusion included in the first blower 10 can be referred to as a first protrusion and the protrusion included in the second blower 20 can be referred to as a second protrusion. However, hereinafter, for the convenience of description, it is not specifically stated whether the first blower 10 includes the first protrusion. However, the second protrusion included in the second blower 20 will be referred to as a protrusion 280.

[0100] Each of the second blowing fan 260 disposed in the inside of the second blower 20 and the third blowing fan 360 disposed in the inside of the flow adjusting device 30 can be embodied as a mixed flow fan.

[0101] In one example, Fig. 6 and Fig. 7 Only the structure of the second blower 20 is illustrated and the structure of the first blower 10 is not illustrated. However, the first blowing fan 16 disposed in the inside of the first blower 10 can be embodied as a mixed flow fan.

[0102] As described above, in a state in which the upper surface of the flow adjusting device 30 and the upper surface of the second blower 20 are oriented horizontally, that is, in a state in which the flow adjusting device 30 is oriented in the first position, the side panel 305 of the flow adjusting device 30 and the second discharge hole 220 of the second blower 20 can be spaced apart from each other in a vertical direction. At least a portion of air discharged from the second discharge hole 220 can be discharged to the outside through a space between the side panel 305 and the second discharge hole 220.

[0103] That is, since the Coandγ effect in which a fluid jet tends to remain attached to a convex surface, at least a portion of air blown upward along the vertical direction using the second blowing fan 260 can be ejected from a portion close to the inner wall of the second housing 200. Then, the air can be directly discharged to the outside through the second discharge hole 220 while bypassing the flow adjusting device 30. Accordingly, components disposed in the flow adjusting device 30 can not serve as unnecessary resistance elements against the air flow. As such, the speed of air discharged from the second blower 20 is not reduced and the blowing distance can be improved. In one example, when the second blower 20 further includes the protrusion 280, the speed of air discharged from the second blower 20 can be increased.

[0111] Fig. 10 to Fig. 18Only the first air passage controller 170 included in the first blower 10 is shown, but the second air passage controller included in the second blower 20 is not shown. However, the second air passage controller can be configured to have substantially the same or similar structure as the first air passage controller 170. Therefore, hereinafter, for convenience of description, only the first air passage controller 170 will be described in detail. The detailed description of the second air passage controller included in the second blower 20 will be omitted.

[0112] The first air passage controller 170 is configured to be rotatable, and is disposed above the first blowing fan 160. The first air passage controller 170 can include a first frame 170a configured to have a cylindrical shape, and a second frame 170b configured to have an upper surface having the same vertical height as that of the first frame 170a, the second frame being spaced apart from the first frame 170a and having a ring shape around the top of the first frame 170a.

[0113] Referring to Fig. 11 to Fig. 13 , the first air passage controller 170 can include an air passage control panel disposed between the first frame 170a and the second frame 170b. One end of the control panel is fixed to the first frame 170a, and the other end thereof is fixed to the second frame 170b. The control panel is configured to partially cover the space between the first frame 170a and the second frame 170b. The first air passage controller 170 can include an air passage control link 180 disposed in the inside of the first frame 170a. The air passage control link 180 can be connected to the other end of the air passage control panel, and is configured to cause opening and closing of the air passage control panel. A concentrated air passage 190 can be provided on a portion of the space between the first frame 170a and the second frame 170b which is not covered by the air passage control panel.

[0114] Further, the first air passage controller 170 can include a first actuator disposed in the inside of the first frame 170a and configured to drive the rising and falling of the air passage control link 180.

[0115] The first actuator can include a first motor 183 to provide power, a first shaft configured to protrude from one end of the first motor 183 and configured to be rotatable, and a first wheel 184 coupled to the first shaft. On a portion of an inner wall of the air passage control link 180, a first rail 187 extending in a vertical direction can be provided. The air passage control link 180 can be controlled so that the first wheel 184 rises or falls when rotating in engagement with the first rail 187.

[0116] The second actuator can include a second motor 173 to provide power, a second shaft configured to protrude from one end of the second motor 173 and configured to be rotatable, and a second wheel 174 fastened to the second shaft. On a portion of an inner wall of the first housing 100, a second rail 177 extending in a horizontal direction horizontal to the ground can be provided. The first frame 170a can be controlled to rotate in a circumferential direction along the inner wall of the first housing 100 when the second wheel 174 rotates in engagement with the second rail 177.

[0117] The air passage control panel can include a plurality of control panels 175 and a plurality of through members 171 each passing through the control panel 175 and integrally formed with the control panel 175. Each through member 171 can be configured to sequentially extend through the second frame 170b, the control panel 175, and the first frame 170a in a horizontal direction.

[0118] In an exemplary embodiment, each control panel 175 can have a ring band sector shape in which both a trapezoidal top side and a bottom side are circular. The plurality of control panels 175 can be arranged to partially fill a space between the first frame 170a and the second frame 170b.

[0119] The through member 171 can be configured to extend through the first frame 170a in one horizontal direction, then extend on an upper surface of the air passage control link 180, and thereafter bend and extend in another horizontal direction different from the one horizontal direction.

[0120] In an exemplary embodiment, the through member 171 can be configured to extend through the first frame 170a in a first direction of a horizontal direction, then extend on an upper surface of the air passage control link 180, and thereafter bend and extend in a second direction of the horizontal direction different from the first direction. In one embodiment, the first direction and the second direction can be orthogonal to each other.

[0121] Hereinafter, a portion of the through member 171 extending in the first direction will be referred to as a first portion. A portion of the through member 171 extending in the second direction will be referred to as a second portion.

[0122] The air passage control link 180 can include a through fastener 181 configured to protrude from the upper surface. A through member 171 extending from the control panel 175 and passing through one end of the second frame 170b can be fastened to the second frame 170b. A through member 171 extending from the control panel 175 and passing through the other end of the first frame 170a can pass through the through fastener 181 and be fastened to the air passage control link 180.

[0123] In an exemplary embodiment, the air passage control link 180 can have a ring shape surrounded by the inner wall of the first frame 170a when viewed from above. The side wall of the first frame 170a can have a ring shape surrounding the peripheral surface of the air passage control link 180. The second frame 170b can have a ring shape spaced apart from the first frame 170a.

[0124] A plurality of control panels 175 included in the air passage control panel can be uniformly arranged in a circumferential direction along the peripheral surface of the first frame 170a in a space between the first frame 170a and the second frame 170b. The control panel 175 can be disposed in a portion of the space between the first frame 170a and the second frame 170b. Accordingly, air discharged from the first blowing fan 160 can flow in the concentrated air passage 190, which can be disposed in a portion of the space not covered by the control panel 175.

[0125] The concentrated air passage 190 can be generated only when the air passage control link 180 is raised via the first actuator control. When the air passage control link 180 is lowered via the first actuator control, the passage 190 can not be generated.

[0127] Reference Fig. 14 to Fig. 16 The air passage control link 180 can be controlled to be lowered via the first actuator. Accordingly, the air passage control panel can be opened.

[0128] Specifically, when the first wheel 184 of the first actuator rotates in a manner engaged with the first rail 187 provided on the inner surface of the air passage control link 180 so as to control the air passage control link 180 to descend, the through fastener 181 provided on the upper surface of the air passage control link 180 descends together with the air passage control link 180. The portion of the through member 171 fastened to the through fastener 181, that is, the second portion of the through member 171 bent and extending in the second direction, moves downward in the vertical direction. The remaining portion of the through member 171 other than the second portion of the through member 171, that is, the first portion extending in the first direction of the through member 171, can rotate clockwise or counterclockwise. The control panel 175 fixed to the first portion of the through member 171 can rotate together with the through member 171.

[0129] Accordingly, as the plurality of control panels 175 individually rotate, the air passage control panel can be partially opened. The air discharged from the first blowing fan 160 can move through a specific portion of the space between the first frame 170a and the second frame 170b. In this regard, the specific portion of the space refers to a space in which the concentrated air passage 190 is not provided.

[0130] Fig. 16 It is illustrated that each of the plurality of control panels 175 is rotated to form an angle that is not perpendicular to the second frame 170 when viewed from the side. However, the concept of the present disclosure need not be limited thereto. Each of the plurality of control panels 175 can be rotated to form an angle that is perpendicular to the second frame 170.

[0131] Although not illustrated in the drawings, the lower surface of the first frame 170a can be configured to have a first opening and a second opening defined at positions corresponding to the outer peripheral portion of the air passage control link 180 and the lower portion of the first rail 187, respectively. The first opening can refer to a region through which the outer peripheral portion of the air passage control link 180 passes through the lower surface of the first frame 170a in the vertical direction when the air passage control link 180 descends. The second opening can refer to a region through which the lower portion of the first rail 187 passes through the lower surface of the first frame 170a in the vertical direction when the air passage control link 180 descends.

[0132] In an exemplary embodiment, in a state in which the air passage control link 180 has descended, the lower portion of the through fastener 181 can protrude downward beyond the lower surface of the first frame 170a in the vertical direction.

[0133] Reference Fig. 17The first rail 187 can be provided to correspond to the position of the first wheel 184. Accordingly, the rising and falling of the air passage control link 180 can be controlled by the first actuator.

[0134] Referring to Fig. 18 The second rail 177 can be provided to be in contact with the second wheel 174. Accordingly, the rotation of the air passage control link 180 in the circumferential direction can be controlled by the second actuator.

[0135] Although not shown, the first frame 170a can include a third opening passing through the lower surface of the first frame 170a in the vertical direction. A second shaft fastened to the second actuator and the second wheel 174 can move in the circumferential direction and along the third opening. The third opening can be formed to partially pass through the lower surface of the first frame 170a in the circumferential direction around a central region of the lower surface of the first frame 170a.

[0136] In an exemplary embodiment, when the first frame 170a is rotated in one direction via the second actuator, the other end of the air passage control panel fixed to the first frame 170a can be rotated in the one direction. Accordingly, the concentrated air passage 190 can be controlled to be rotated in the one direction.

[0137] As described above, when the air passage control link 180 has been lowered via the first actuator, the other end of the through member 171 fastened to the through fastener 181 is lowered therewith, so that the control panel 175 formed integrally with the through member 171 can be rotated in the one direction, so that the air passage control panel can be controlled to be opened. Accordingly, when the air passage control link 180 is controlled to be raised, a portion of the flow area through which air flows between the first blowing fan 160 and the first discharge hole 120 can be selectively closed. Accordingly, the air discharged from the first blowing fan 160 can be controlled to be selectively blown to a specific area.

[0138] Conversely, when the air passage control link 180 is raised via the first actuator, the other end of the through member 171 fastened to the through fastener 181 is raised therewith, so that the control panel 175 formed integrally with the through member 171 can be rotated in a direction opposite to the one direction, so that the air passage control panel can be controlled to be closed. Accordingly, when the air passage control link 180 is controlled to be lowered, the entire flow area through which air flows between the first blowing fan 160 and the first discharge hole 120 can be opened. Accordingly, the air discharged from the first blowing fan 160 can be controlled to be uniformly blown to all areas.

[0139] Further, the air passage control panel 180 can be rotated in a circumferential direction along the inner wall of the first housing 100 via the second actuator. Accordingly, the concentrated air passage 190 can be controlled to be rotated in the circumferential direction.

[0147] The fourth actuator and the second foreign matter purifier included in the second blower 20 can be configured to have the same or similar structures as the third actuator and the first foreign matter purifier included in the first blower 10, respectively. Therefore, hereinafter, for convenience of description, only the third actuator and the first foreign matter purifier included in the first blower 10 will be described in detail. Detailed description of the fourth actuator and the second foreign matter purifier included in the second blower 20 will be omitted.

[0148] Reference Fig. 21 to Fig. 23The first foreign matter purifier can include a first dust collecting plate 140 configured to form a portion of a side wall of the first housing 100, a first foreign matter cleaning module 145 fixed to an inner wall of the first dust collecting plate 140 and configured to contact an outer side wall of the first filter member 130, a first through-hole 149a configured to pass through the side wall of the first dust collecting plate 140, and a door 155 provided at an outer side wall of the housing so as to open or close the first through-hole 149a.

[0149] The third actuator can include a third motor 131 to provide power, a third shaft configured to protrude from one end of the third motor 131 and be rotatable, and a third wheel 132 fastened to the third shaft.

[0150] Between the first filter member 130 and the third actuator, a first lower plate 125 can be disposed below the first filter member 130 and can be configured to rotate the first filter member 130. A third rail 133 extending in a circumferential direction around a central area of the first lower plate 125 can be disposed below the first lower plate 125. The third wheel 132 can be configured to rotate in engagement with the third rail 133. Accordingly, the first filter member 130 can be controlled to rotate in a circumferential direction along an inner wall of the first lower plate 125 via the third actuator.

[0151] Referring to Fig. 20 and Fig. 21 The first upper plate can be formed above the first filter member 130. Between the first filter member 130 and the first upper plate, a first support 135 can be disposed, which is configured to reduce a frictional force generated when the first filter member 130 rotates.

[0152] As the first filter member 130 is rotated via the third actuator, foreign matters attached to the outer side wall of the first filter member 130 are separated therefrom by the first foreign matter cleaning module 145 and then discharged through the first through-hole 149a. In one embodiment, the first through-hole 149a can be disposed at a central area of the side wall of the first dust collecting plate 140.

[0153] The first foreign matter cleaning module 145 can include a first foreign matter cleaning member 145a extending in a vertical direction and configured such that both ends thereof are fixed to a top and a bottom of an inner wall of the first dust collecting plate 140, and a second foreign matter cleaning member 145b extending in the vertical direction and fixed to the first foreign matter cleaning member 145a.

[0156] A hollow space between the first filter member 130 and the inner wall of the first dust collecting plate 140, except for a region in which the first foreign matter cleaning module 145 is disposed, can serve as an air passage through which foreign matter removed from the outer side wall of the first filter member 130 by the first foreign matter cleaning module 145 can move.

[0157] In one example, the first housing 100 can further include a second through-hole 149b configured to pass through a side wall of the first housing 100 and disposed to correspond to a position in which the first through-hole 149a is disposed. The first through-hole 149a and the second through-hole 149b in combination can define the first through-hole 149. A diameter of the second through-hole 149b can be greater than a diameter of the first through-hole 149a.

[0158] The vibration absorbing member 150 can be disposed between the first through-hole 149a and the second through-hole 149b. The vibration absorbing member 150 can be made of an elastic rubber material in order to alleviate an impact generated when the external foreign matter purifier approaches the first through-hole 149.

[0159] In an exemplary embodiment, the vibration absorbing member 150 can be configured to have a ring shape, a central portion of which is hollow. A diameter of the ring shape can be smaller than a diameter of the second through-hole 149b and greater than or equal to a diameter of the first through-hole 149a.

[0160] In one example, the vibration absorbing member 150 can include a detection sensor capable of recognizing the external foreign matter purifier. When the detection sensor detects the external foreign matter purifier, the third actuator can be controlled to be activated.

[0161] To illustrate the inner wall of the third rail 133, Fig. 22 The third wheel 132 is not illustrated. To avoid repetitive explanation, Fig. 23 The third motor 131 is not illustrated. However, it can be easily understood by one of ordinary skill in the art to which the disclosure pertains that the third wheel 132 is engaged with the top of the third motor 131 and rotates along the third rail 133 provided between the first lower plate 125 and the third motor 131.

[0162] Referring to Fig. 24 to Fig. 26 A first door 155 for opening or closing the first and second through holes 149a and 149b can be provided on the outer side wall of the first housing 100.

More specifically, Fig. 24 It is illustrated that the first door 155 is closed. Fig. 25 It is illustrated that the first door 155 is open. Fig. 26 It is illustrated that the first filter member 130 provided in the inside of the first housing 100 is cleaned using the external foreign matter purifier when the first door 155 is open.

[0164] In one embodiment, the third actuator can be activated only when the first door 155 is open. When the first door 155 is in the closed state, the third actuator can be deactivated.

[0165] As described above, the first filter member 130 provided in the inside of the first blower 10 can be controlled to rotate in the circumferential direction via the third actuator provided below the first filter member 130. Foreign matter attached to the outer side wall of the first filter member 130 can be separated therefrom using the first foreign matter cleaning module 145 configured to at least partially contact the outer side wall of the first filter member 130. Thereafter, the foreign matter separated from the first filter member 130 can be removed through the first through hole 149 using the external foreign matter purifier provided outside the first blower 10. Therefore, a user of the air purifier 1 can easily clean the first filter member 130 provided in the inside of the first blower 10 without disassembly.

[0171] The flow regulating device 30 can be disposed above the second blower 20 and can be configured to suck air discharged from the second blower 20 and control a discharge direction of the sucked air.

[0172] The guide member 40 can be configured such that one end thereof is introduced into the inside of the second blower 20 and the other end thereof is connected to the flow regulating device 30. The guide member 40 can be controlled to be retracted into the inside of the second blower 20 or to extend from the upper surface of the second blower 20 so as to cause a position change of the flow regulating device 30. In an exemplary embodiment, an angle formed between the upper surface of the flow regulating device 30 and the upper surface of the second blower 20 can increase or decrease according to the degree to which the guide member 40 extends from the upper surface of the second blower 20.

[0173] According to the operation of the guide member 40, the position of the flow regulating device 30 can be switched between a first position in which the upper surface of the flow regulating device 30 is parallel to the upper surface of the second blower 20, a second position in which the upper surface of the flow regulating device 30 is oriented to form a predetermined angle with respect to the upper surface of the second blower 20, and a third position in which the upper surface of the flow regulating device 30 is perpendicular to the upper surface of the second blower 20.

[0174] Fig. 28 and Fig. 29 It is shown that the flow regulating device 30 is oriented in the first position.

[0175] ReferringFig. 28 and Fig. 29 The guide member 40 can include an outer case 400 defining an outer appearance and having one end configured to enter an inside of the second blower 20 and the other end configured to extend from an upper surface of the second blower 20, and an inner case 405 having one end introduced into the inside of the outer case 400 and the other end connected to the flow regulating device 30. The other end of the inner case 405 is configured to extend from the other end of the outer case 400 opposite to the one end of the outer case 400 received in the inside of the second blower 20. The outer case 400 can have a structure partially surrounding the inner case 405.

[0176] In an exemplary embodiment, the outer case 400 can have a substantially curved cylindrical shape. The cylindrical size of the inner case 405 is relatively smaller than the cylindrical size of the outer case 400. In this regard, the cylindrical shape of the outer case 400 is configured such that an upper surface thereof is open. The inner case 405 can be introduced into the inside of the outer case 400 or can extend from an open top surface of the outer case 400.

[0177] An angle defined between the upper surface of the flow regulating device 30 and the upper surface of the second blower 20 can be primarily increased or decreased according to a degree to which the outer case 400 extends from the second blower 20. The angle defined between the upper surface of the flow regulating device 30 and the upper surface of the second blower 20 can be secondarily further increased or decreased according to a degree to which the inner case 405 extends from the outer case 400.

[0178] In an exemplary embodiment, when the flow regulating device 30 is oriented in the first position, the outer case 400 can be introduced into the inside of the second blower 20 and can not be exposed to the outside.

[0179] The guide member 40 includes a fourth actuator 420 disposed inside the second blower 20 and close to an outer face of the outer case 400, and a fifth actuator 430 disposed inside the inner case 405 and close to an inner face of the outer case 400.

The fifth actuator 430 can include a fifth motor 431 to supply power, a fifth shaft 433 configured to protrude from one end of the fifth motor 431 and be rotatable, and a fifth wheel 435 fastened to the fifth shaft 433.

[0181] Referring to Fig. 29 and Fig. 34, the housing 400 can include a first guide rail 410a configured to extend across an outer face of the housing 400 in a longitudinal direction thereof, and a second guide rail 410b configured to extend across an inner face of the housing 400 in the longitudinal direction. Each of the first guide rail 410a and the second guide rail 410b can extend across the central region along the longitudinal direction of the housing 400. The first guide rail 410a and the second guide rail 410b can face each other. The first guide rail 410a and the second guide rail 410b can be integrally formed with each other so as to form the guide rail 410.

[0182] Referring to Fig. 29 and Fig. 34 , the inner housing 405 can include a groove 407 configured to extend across an outer face of the inner housing 405 in the longitudinal direction, and a fourth opening oriented through a portion of the groove 407.

[0183] The groove 407 can have a recessed shape into the outer face of the inner housing 405, and can be formed corresponding to a position of the second guide rail 410b. That is, the second guide rail 410b formed on the inner face of the housing 400 can have a shape protruding toward the outer face of the inner housing 405. In this regard, the groove 407 has a recessed shape into the outer face of the inner housing 405. As such, the inner housing 405 can be extended from the housing 400 without being caught by the second guide rail 410b.

[0184] The fourth opening can have various shapes, such as a polygonal shape and / or a circular shape. The fourth opening can be formed corresponding to a position of the fourth wheel 435 of the fourth actuator 430. That is, the fourth wheel 435 can be engaged with the second guide rail 410b formed on the inner face of the housing 400 through the fourth opening. As the fourth wheel 435 rotates, the inner housing 405 can be retracted into the housing 400 or extended from the housing 400.

[0185] In an exemplary embodiment, the fourth opening can be closer to one end of the inner housing 405 introduced inside the housing 400 than the other end of the inner housing 405 connected to the flow regulating device 30.

[0186] The fourth wheel 425 disposed inside the second blower 20 can be configured to rotate in engagement with the first guide rail 410a. The fifth wheel 435 disposed inside the inner housing 405 can be configured to rotate in engagement with the second guide rail 410b. In an exemplary embodiment, the fifth wheel 435 can be closer to one end of the inner housing 405 introduced inside the housing 400 than the other end of the inner housing 405 connected to the flow regulating device 30.

[0187] Fig. 30 and Fig. 31It is shown that the flow regulating device 30 is oriented in the second position.

[0188] Referring to Fig. 30 and Fig. 31 , the position of the flow regulating device 30 can be switched between the first position and the second position based on the rotational motion of the fourth wheel 425 included in the fourth actuator 420. In this case, the fifth wheel 435 included in the fifth actuator 430 can be controlled not to rotate.

[0189] Specifically, the outer case 400 can be controlled to be retracted into the inside of the second hair dryer 20 or to extend from the upper surface of the second hair dryer 20 via the rotational motion of the fourth wheel 425. Accordingly, the position of the flow regulating device 30 can be switched between the first position and the second position.

[0190] That is, while the fourth wheel 425 is engaged with the first guide rail 410a, the outer case 400 can extend from the upper surface of the second hair dryer 20 as it rotates in one direction. In this way, the flow regulating device 30 can be raised. Conversely, as the fourth wheel 425 is engaged with the first guide rail 410a and rotates in a direction opposite to the one direction, the outer case 400 can be introduced into the inside of the second hair dryer 20. In this case, the flow regulating device 30 can be lowered.

[0191] In an exemplary embodiment, the fifth wheel 435 can be controlled to rotate until the flow regulating device 30 is oriented to the second position, and can be controlled to rotate only after the flow regulating device 30 is oriented in the second position.

[0192] In an exemplary embodiment, when the flow regulating device 30 is oriented in the second position, the outer case 400 can extend at least partially from the second hair dryer 20 and be exposed to the outside, and the inner case 405 is retracted into the inside of the outer case 400 and is not exposed to the outside.

[0193] Fig. 32 to Fig. 34 It is shown that the flow regulating device 30 is oriented in the third position.

[0194] Referring to Fig. 32 to Fig. 34 , the flow regulating device 30 can be oriented in the second position or the third position based on the rotational motion of the fifth wheel 435 included in the fifth actuator 430.

[0195] Specifically, the inner case 405 can be controlled to be retracted into the outer case 400 or to extend from the outer case 400 via the rotational motion of the fifth wheel 435. Accordingly, the flow regulating device 30 can be oriented in the second position or the third position.

[0196] That is, as the fifth wheel 435 engages with the second guide rail 410b through the fourth opening and then rotates in one direction, the inner case 405 can extend from the other end of the outer case 400. In this case, the flow adjustment device 30 can be raised. In contrast, as the fifth wheel 435 engages with the second guide rail 410b through the fourth opening and then rotates in a direction opposite to the one direction, the inner case 405 can be introduced into the inside of the outer case 400. In this case, the flow adjustment device 30 can be lowered.

[0197] In an exemplary embodiment, when the flow adjustment device 30 is oriented in the third position, the outer case 400 can extend from the second blower 20 and be exposed to the outside. The inner case 405 can extend from the outer case 400 and can be exposed to the outside.

[0198] As described above, the air purifier 1 according to an exemplary embodiment of the present disclosure can include the blowers 10 and 20, the guide member 40, and the flow adjustment device 30, which are sequentially stacked.
