Description

TECHNICAL FIELD

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

[0002] An air cleaner is understood as a home appliance that sucks and filters contaminated air and then discharges the filtered air, and is configured to purify an indoor space such as a living room or an office. In general, the air cleaner includes a blower configured to suck external air and discharge the sucked air, and a filter provided inside the blower to filter dust, bacteria, etc. in the air. In this regard, the air cleaner can further include a flow adjustment device configured to adjust a discharge direction of the air discharged from the blower. However, because the operation radius of the flow adjustment device is limited, it is not possible to blow the air 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 further including a flow adjustment device configured to adjust a discharge direction of the air discharged from the blower. In the air cleaner of the related art 1, the air sucked into the blower is filtered by the filter provided inside the blower and then discharged along a vertical direction perpendicular to a top surface of the blower. Thereafter, the air discharged from the blower is blown along a direction different from the vertical direction by the flow adjustment device.

[0004] However, even if the air cleaner of the related art 1 is used, it brings an inconvenience that the air discharged from the blower is blown only along the vertical direction or a direction forming a predetermined angle with respect to the top surface of the blower, but not along a horizontal direction parallel to the top surface of the blower.

[0005] Another related art (Korean Patent Application Publication No. 10-2019-0120126, hereinafter referred to as related art 2) discloses an air cleaner including a flow adjustment device configured to adjust a discharge direction of the air discharged from the blower, and a rotation guide configured to cause rotation of the flow adjustment device. In the air cleaner of the related art 2, the position of the flow adjustment device can be changed based on the degree of withdrawal of the rotation guide, and the air discharged from the blower can be blown along a direction different from the vertical direction by the flow adjustment device based on the degree of withdrawal of the rotation guide.

[0006] However, even if the air cleaner of the prior art 2 is used, because the space in which the rotary guide can be disposed is limited within the blower, the length of the rotary guide cannot be secured for changing the orientation to the orientation in which the top surface of the flow adjustment device is perpendicular to the top surface of the blower. Therefore, there is a limitation in that the air discharged from the blower is difficult to be blown in the desired direction. SUMMARY

[0072] Referring to Figures 6 to 8 The guide member 40 can include a plurality of links 415 and 425 arranged below the flow regulating device 30 and configured to change the state of the flow regulating device 30.

[0073] One end of each of the plurality of links 415 and 425 can be pivotably connected to an inner portion of the guide member 40, and the other end of each of the plurality of links 415 and 425 can be pivotably connected to a portion provided on a bottom surface of the flow regulating device 30. The flow regulating device 30 can be configured to change the discharge direction of air by pivoting of at least one of the plurality of links 415 and 425 of the guide member 40.

[0074] In detail, the guide member 40 can include a first case 400 provided on a top surface of the blowers 10 and 20, a second case 410 coupled to the first case 400 to be raised and lowered, a guide connector 420 provided to be pivoted by being coupled to a bottom surface of the flow regulating device 30 and a portion of the second case 410, respectively, a first link 415 having one end coupled to an inner portion of the first case 400 and the other end coupled to an inner portion of the guide connector 420, and a second link 425 provided to be spaced apart from the first link 415, having one end coupled to the inner portion of the first case 400 and the other end coupled to the inner portion of the guide connector 420. In this regard, the length of the second link 425 can be shorter than the length of the first link 415.

[0075] The bottom surface of the flow regulating device 30 can have a convex portion protruding toward the first case 400, and a side wall of the guide connector 420 can have a concave portion having a shape corresponding to the convex portion of the flow regulating device 30. The bottom surface of the flow regulating device 30 and the side wall of the guide connector 420 can be engaged with each other. The bottom surface of the flow regulating device 30 and the side wall of the guide connector 420 can be fastened and fixed to each other by various methods such as fitting fastening, rivet fastening, and screw fastening.

[0076] In an exemplary embodiment, a space in which the second case 410 is accommodated can be defined within the first case 400. The space defined within the first case 400 can have a larger volume than the second case 410, so that the second case 410 does not collide with an inner wall of the first case 400 when pivoted. In one embodiment, the inner wall of the first case 400 can have a locally curved portion, and the second case 410 can be pivoted along the curved portion of the inner wall of the first case 400.

[0077] A space in which the first link 415 and the second link 425 can be pivoted can be defined within the second housing 410, and a space in which the other end of the first link 415 and the other end of the second link 425 can be pivoted can be defined within the guide connector 420.

[0078] Figures 6 to 8 It is illustrated that each of the first housing 400, the second housing 410, and the guide connector 420 has a specific shape, but the concept of the present disclosure is not necessarily limited thereto. That is, each of the first housing 400, the second housing 410, and the guide connector 420 can have various shapes within a range that does not impair its original function.

[0079] In addition, even though not shown, an inner circumferential surface of the guide connector 420 covered by the second housing 410 can include openings that communicate with the first link 415 and the second link 425, respectively, and each of the openings can extend a radius in which each of the first link 415 and the second link 425 is pivoted.

[0080] In an exemplary embodiment, when the air cleaner 1 includes the first blower 10 and the second blower 20 stacked in sequence, the guide member 40 can be disposed on the second blower 20, for example, on the second blowing fan 260. In one embodiment, when the air cleaner 1 includes only one blower (for example, the first blower 10), the guide member 40 can be disposed on the first blower 10, for example, on the first blowing fan 160. Otherwise, when the air cleaner 1 includes only the second blower 20, the guide member 40 can be disposed on the second blower 20, for example, on the second blowing fan 260.

[0081] The first housing 400 can include a first link connector 413 disposed to be coupled to one end of the first link 415, and the guide connector 420 can include a second link connector 417 disposed to be coupled to the other end of the first link 415. One end of the first link 415 can be connected to the first link connector 413 so as to pivot about the first link connector 413, and the other end of the first link 415 can be connected to the second link connector 417 so as to pivot about the second link connector 417.

[0082] The first housing 400 can further include a third link connector 423 disposed to be coupled to one end of the second link 425, and the guide connector 420 can further include a fourth link connector 427 disposed to be coupled to the other end of the second link 425. One end of the second link 425 can be connected to the third link connector 423 so as to pivot about the third link connector 423, and the other end of the second link 425 can be connected to the fourth link connector 427 so as to pivot about the fourth link connector 427.

[0083] In an exemplary embodiment, a shortest distance between the guide connector 420 and the third link connector 423 can be less than a shortest distance between the guide connector 420 and the first link connector 413.

[0084] In an exemplary embodiment, the second link connector 417 can be disposed within the guide connector 420 to be spaced apart from an inner circumferential surface of the guide connector 420, and the fourth link connector 427 can be disposed within the guide connector 420 to be adjacent to the inner circumferential surface of the guide connector 420.

[0085] In an exemplary embodiment, the second link 425 can be positioned within the first housing 400 and in front of the first link 415 in a horizontal direction, and can be disposed to be relatively adjacent to an inner wall of the first housing 410.

[0086] The second link 425 can be configured to pivot in the same direction as a pivoting direction of the first link 415 when the first link 415 pivots. That is, when the first link 415 pivots about the first link connector 413 in one direction (counterclockwise direction in Figures 6 to 8 FIGS. 1 and 2, and hereinafter referred to as a first direction), the second link 425 indirectly connected to the first link 415 through the guide connector 420 can also pivot about the third link connector 423 in the first direction.

[0087] In addition, since the guide connector 420 is coupled to a portion of the second housing 410, the second housing 410 can also pivot about the first link connector 413 together with the first link 415 as the first link 415 pivots.

[0088] In one example, when the first link 415 pivots in the first direction, the guide connector 420 can be configured to pivot in a direction opposite to the pivoting direction of the first link 415 (clockwise direction in Figures 6 to 8 FIGS. 1 and 2, and hereinafter referred to as a second direction). The fourth link connector 427 disposed within the guide connector 420 can also pivot in the second direction together with the guide connector 420. That is, the fourth link connector 427 can be connected to the second link connector 417 so as to pivot about the second link connector 417, as shown in Figure 6 FIGS. 1 and 2.

[0089] When the first link 415 and the second housing 410 pivot together about the first link connector 413 in the first direction in the first direction, the guide connector 420 disposed at a distance from the first link connector 413 can be controlled to rise from the first housing 400.

[0090] The guide connector 420 can be configured to pivot in the second direction while being controlled to rise from the first housing 400, and a fourth link connector 427 disposed within the guide connector 420 can also be configured to pivot in the second direction together with the guide connector 420.

[0091] Specifically, the guide connector 420 can be connected to the first link 415 through the second link connector 417, and can be connected to the second link 425 through the fourth link connector 427. In this regard, the second link 425 can be shorter in length than the first link 415, and can be disposed in front of the first link 415 in the horizontal direction, the fourth link connector 427 is coupled to the other end of the second link 425, and is disposed to be spaced apart from the inner circumferential surface of the guide connector 420, and the second link connector 417 is coupled to the other end of the first link 415, and is disposed adjacent to the inner circumferential surface of the guide connector 420. Therefore, when the first link 415 and the second housing 410 pivot together, the guide connector 420 can be controlled to rise from the first housing 400, and at the same time, be controlled to pivot in the second direction. In this regard, the fourth link connector 427 disposed adjacent to the inner circumferential surface of the guide connector 420 can be controlled to pivot about the second link connector 417 disposed to be spaced apart from the inner circumferential surface of the guide connector 420.

[0092] Therefore, as the second housing 410 pivots in the first direction, and at the same time, the guide connector 420 pivots in the second direction, the state of the flow regulating device 30 can change from a state in which the top surface of the flow regulating device 30 is horizontal to the top surfaces of the blowers 10 and 20 (i.e., a state in which the flow regulating device 30 is oriented in the first position) to a state in which the top surface of the flow regulating device 30 is perpendicular to the top surfaces of the blowers 10 and 20 (i.e., a state in which the flow regulating device 30 is oriented in the third position).

[0093] In one example, the concept of the operation method of the guide connector 420 described thus far can be applied in reverse. That is, when the second housing 410 pivots in the second direction, the guide connector 420 can be configured to descend toward the first housing 410, and at the same time, pivot in the first direction. At this time, the fourth link connector 427 disposed adjacent to the inner circumferential surface of the guide connector 420 can also be configured to pivot in the first direction together with the guide connector 420.

[0094] Accordingly, as the second housing 410 is pivoted in the second direction and at the same time, the guide connector 420 is pivoted in the first direction, the state of the flow regulating device 30 can be changed from a state in which the top surface of the flow regulating device 30 is perpendicular to the top surface of the blowers 10 and 20 (i.e., a state in which the flow regulating device 30 is oriented in the third position) to a state in which the top surface of the flow regulating device 30 is horizontal to the top surface of the blowers 10 and 20 (i.e., a state in which the flow regulating device 30 is oriented in the first position).

[0095] Referring to Figure 7 and Figure 8 As the state of the flow regulating device 30 is changed from the first position to the third position, each of the second link connector 417 and the fourth link connector 427 is positioned at a higher vertical height than before. In this regard, since the length of the second link 425 can be shorter than the length of the first link 415, the fourth link connector 427 connected to the other end of the second link 425 can have a smaller degree of increase in vertical height than the second link connector 417 connected to the other end of the first link 415. Accordingly, in the state in which the flow regulating device 30 is oriented in the second position or the third position, the fourth link connector 427 can be disposed at a lower vertical height than the second link connector 417.

[0096] Referring to Figure 6 The first link 415 and the second link 425 can be arranged on different planes, and can respectively have portions overlapping each other when the flow regulating device 30 is oriented in the first position. However, the concept of the present disclosure is not necessarily limited thereto. That is, the first link 415 and the second link 425 can be arranged on the same plane. In this case, the first link 415 and the second link 425 can respectively not have portions overlapping each other when the flow regulating device 30 is oriented in the first position. Otherwise, the first link 415 and the second link 425 can be arranged on different planes, and can respectively not have portions overlapping each other when the flow regulating device 30 is oriented in the first position.

[0097] As described above, the air cleaner 1 according to the exemplary embodiments of the present disclosure can include the blowers 10 and 20, the guide member 40, and the flow adjustment device 30 stacked in sequence, and the guide member 40 can include a plurality of links 415 and 425. In this regard, the one end of each of the plurality of links 415 and 425 can be pivotably connected to the inner portion of the guide member 40, and the other end of each of the plurality of links 415 and 425 can be pivotably connected to a portion provided on the bottom surface of the flow adjustment device 30. The flow adjustment device 30 can be configured to change the discharge direction of air by pivoting of at least one link of the plurality of links 415 and 425 of the guide member 40.

[0098] In this regard, the angle formed between the top surface of the flow adjustment device 30 and the top surfaces of the blowers 10 and 20 can be increased or decreased based on the operation of the plurality of links 415 and 425. The state of the flow adjustment device 30 can be changed from a first position in which the top surface of the flow adjustment device 30 is horizontal to the top surfaces of the blowers 10 and 20 to a third position in which the top surface of the flow adjustment device 30 is perpendicular to the top surfaces of the blowers 10 and 20.

[0099] Accordingly, the top surface of the flow adjustment device 30 can be oriented to be perpendicular to the top surfaces of the blowers 10 and 20. In this way, the air discharged from the blowers 10 and 20 can be blown further in a desired direction through the flow adjustment device 30.

[0100] In addition, the guide member 40 according to the exemplary embodiments of the present disclosure can have a stable and improved appearance because it can not only be driven more simply and naturally, but also the structure for driving the guide member 40 is not exposed to the outside, compared to a conventional guide member configured to be movable by being inserted into or withdrawn from the blower.

[0101] Although various embodiments of the present disclosure have been described in detail above, those skilled in the art who possess the ordinary knowledge in the art to which the present disclosure belongs can recognize that various modifications can be made to the above-described embodiments, as long as they do not depart from the scope of the present disclosure. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the claims described below and their equivalents.
