The present invention relates to an indoor unit for an air conditioner, and more particularly to a filter installed in the indoor unit.
An indoor unit for an air conditioner may adjust required indoor temperature by discharging air heat-exchanged with a refrigerant to an indoor space. The indoor unit for the air conditioner suctions indoor air through an suction port, make the suctioned air to exchange heat with a refrigerant, and discharge the heat-exchanged air to an discharge port.
An indoor unit for the air conditioner may be divided into a ceiling-mounted type, a wall-mounted type, and a standalone type. In a standalone indoor unit, an outlet may be formed at the front side or either side (right or left) of a cabinet, and an suction port may be formed at the rear side of the cabinet.
Since the stand-alone indoor unit is disposed with an outlet facing an indoor space, an outlet disposed at the rear side of cabinet is disposed to face a wall surface or an edge of the indoor space. Therefore, even a filter disposed at the suction port to filter foreign substances may be disposed at a rear surface of the cabinet.
It is difficult to change an installation position of the stand-alone indoor unit due to size and/or weight of the product or arrangement of a refrigerant tube. Thus, a user should separate or install the filter from the back of the cabinet. This may cause inconvenience to the user due to limitation in a space where the air suction unit is installed.
Korean Patent Application Publication No. 10-2017-0076015 discloses a conventional structure in which a suction port is formed in the rear and a filter member disposed at the suction port is mounted to an installation bracket. The structure has the filter member disposed at the rear side where the suction port is formed, and the filter member is inserted into or drawn from a detachment hole formed in a lateral direction of the installation bracket.
This structure requires a user to be positioned at a rear side of the indoor unit when inserting the filter member into a case of the indoor unit or drawing the filter member therefrom. In addition, this structure has a limitation in terms of installation in that a separate space is needed to draw the filter member from a side surface of the indoor unit.
Multiple types of filters can be installed at a suction port to improve cleanness of an indoor space, remove fine dust, or remove odor. Such filters should be installed or detached at a rear side of a cabinet where the suction port is formed. There is a spatial limitation in forming a suction port, and thus, multiple structures should be coupled to install multiple types of filters, which requires more complicated operations.
The present disclosure solves the above-mentioned problems. One object of the present invention is to provide an indoor unit in which a filter is capable of being easily mounted to a suction port formed in rear of the indoor unit.
Another object of the present invention is to provide an indoor unit in which a suction port and a filter are installed in different areas.
Yet another object of the present invention is to provide an indoor unit in which a plurality of filters is capable of being easily mounted at a suction port formed in rear of the indoor unit.

<Coupling Relation of Filter Module/Coupling Relation Between Filter Module and Filter Mounting Member>
Hereinafter, a coupling relation of a filter module and a coupling relation between the filter module and a filter mounting member will be described with reference to
Here, the upward, downward, leftward, rightward, forward, and rearward directions are described with reference to the case where the filter module 62 is mounted to the filter mounting member 61 to be disposed in rear of the upper cabinet 11. In addition, an upward and downward direction is defined as a longitudinal direction of the filter module 62, a leftward and rightward direction is defined as a lateral direction of the filter module 62, and a forward and rearward direction is defined as a width direction of the filter module 62.
The filter module 62 may be mounted to the filter mounting member 61 when coupling of the filter module 62 is completed. When a dust collecting filter unit 623 and a deodorization filter unit 624 are mounted to a filter case 622, it may be considered that coupling of the filter module 62 is completed.
The filter module 62 may be slidably mounted to the filter mounting member 61. The filter module 62 is slidably mounted to the filter mounting member 61 in a manner in which an upper bending portion 62214a of the filter module 62 and an upper cover rib 62411 are inserted into an upper guide groove formed on an upper side of the filter mounting member 61. The filter module 62 may be slidably mounted to the filter mounting member 61 in a manner in which a lower bending portion 62215a of the filter module 62 and a lower cover rib 6241262 are inserted into a lower guide groove 6113b formed on a lower side of the filter mounting member 61. The filter module 62 may be inserted into the filter mounting member 61 in the width direction of the lateral direction of the filter module 62 to be mounted thereto.
When the filter module 62 is being mounted to the filter mounting member 61, a movement limiting protrusion 62214c may be disposed on one side of a guide roller 6112, thereby limiting movement of the filter module 62. When the filter module 62 is being mounted to the filter mounting member 61, the movement limiting protrusion 62214c may be disposed on one side of the guide roller 6112 in a direction of drawing the filter module 62. Accordingly, the movement limiting protrusion 62214c may limit movement of the guide roller 6112 in a drawing direction, thereby maintaining a state in which the filter module 62 is mounted to the filter mounting member 61.
When coupling of the filter module 62 is completed, the dust collecting filter unit 623 is disposed between the filter case 622 and the deodorization filter unit 624. When coupling of the filter module 62 is completed, the upper cover rib 62411 of the deodorization filter unit 624 may be disposed to surround the upper bending portion 62214a of the filter case 622. When coupling of the filter module 62 is completed, the upper cover rib 62411 of the deodorization filter unit 624 may be disposed to surround the top and the front of the upper bending portion 62214a of the filter case 622. Likewise, when coupling of the filter module 62 is completed, the lower cover rib 62412 of the deodorization filter unit 624 may be disposed to surround the lower bending portion 62215a of the filter case 622.
When coupling of the filter module 62 is completed, a rear protrusion of the dust collecting filter unit 623 may be inserted into a fixing groove 6227 of the filter case 622. When coupling of the filter module 62 is completed, a front protrusion 62313 of the dust collecting filter unit 623 may be disposed at an end portion of the deodorization filter unit 624. When coupling of the filter module 62 is completed, a lateral protrusion 62312 of the dust collecting filter unit 623 may be disposed to be brought into contact with a dust collecting filter fixing protrusion 6223 formed on a lateral cover 6222 of the filter case 622 or a first fixing protrusion 6225a of a dual fixing protrusion.
When coupling of the filter module 62 is completed, a second fixing protrusion 6225b of the dual fixing protrusion 6225 of the filter case 622 may be disposed between a first outer fixing rib 62413 and a second outer fixing rib 62414 of the deodorization filter unit 624.
When the filter module 62 is mounted to the filter mounting member 61, the upper bending portion 62214a of the filter module 62 and the upper cover rib 62411 are inserted into the upper guide groove formed on the upper side of the filter mounting member 61, and the lower bending portion 62215a of the filter module 62 and the lower cover rib 6241262 are inserted into the lower guide groove 6113b formed on the lower side of the filter mounting member 61.
When the filter module 62 is mounted to the filter mounting member 61, an upper cover 62212 or a lower cover 62213 of the filter case 622 may cover a mobile member fastening surface 6121 or a guide member fastening surface 6131 of the filter mounting member 61.

Hereinafter, the first upper mobile member 631a and the second mobile member 632a will be described with reference to
Each of the first upper mobile member 631a and the second upper mobile member 632a may include: dual links 634a, 634b, 635a, and 635b having different lengths and rotatably connected to the filter mounting members 61a and 61b; and drive transmission links 636a, 636b, 637a, and 637b transferring driving forces of the driving devices 633a and 633b to the dual links 634a, 634b, 635a, and 635b. The first upper mobile member 631a and the second upper mobile member 632a may further include: cabinet fixing frames 638a and 638b fixed to the upper cabinet 11 and rotatably connected to the dual links 634a, 634b, 635a, and 635b; and filter mounting member connection frames 639a and 639b fixed to the filter mounting members 61a and 61b and rotatably connected to the dual links 634a, 634b, 635a, and 635b.
Two links included in the dual links 634a, 634b, 635a, and 635b are rotatably connected to the cabinet fixing frames 638a and 638b and the filter mounting member connection frames 639a and 639b Accordingly, if one link rotates, the other link may rotate as well.
The dual links 634a, 634b, 635a, and 635b may include: first links 634a and 634b rotatably connected to the cabinet fixing frames 638a and 638b and the filter mounting member connection frames 639a and 639b and connected to the drive transmission links 636a, 636b, 637a, and 637b; and second links 635a and 635b spaced apart from the first links 634a and 634b and rotatably connected to the cabinet fixing frames 638a and 638b and the filter mounting member connection frames 639a and 639b.
The first links 634a and 634b have a length that is longer than a length of the second links 635a and 635b. The first links 634a and 634b are disposed closer to the middle portion of the upper cabinet 11, by which the upper cabinet 11 is divided into left and right sides, than the second links 635a and 635b are.
The first links 634a and 634b may include: first connection frame couplers 6341a and 6341b rotatably connected to the filter mounting member connection frames 639a and 639b; first fixing frame couplers 6342a and 6342b rotatably connected to the cabinet fixing frames 638a and 638b; first link bars 6343a and 6343b connecting the first connection frame couplers 6341a and 6341b and the first fixing frame couplers 6342a and 6342b; and transmission link connection parts 6344a and 6344b formed in the first link bars 6343a and 6343b and rotatably connected to the drive transmission links 636a, 636b, 637a, and 637b.
The first links 634a and 634b may be rotatably coupled to the filter mounting member connection frames 639a and 639b with reference to first link-first hinge shafts 6341ah and 6341bh that are formed in the first connection frame couplers 6341a and 6341b. The first links 634a and 634b may be rotatably coupled to the cabinet fixing frames 638a and 638b with reference to first link-second hinge shafts 6342ah and 6342bh that are formed in the first fixing frame couplers 6342a and 6342b.
The transmission link connection parts 6344a and 6344b may be disposed adjacent to the first fixing frame couplers 6342a and 6342b.
The second links 635a and 635b may include: second connection frame couplers 6351a and 6351b rotatably connected to the filter mounting member connection frames 639a and 639b; second fixing frame couplers 6352a and 6352b rotatably connected to the cabinet fixing frames 638a and 638b; and second link bars 6353a and 6353b connecting the second connection frame couplers 6351a and 6351b and the second fixing frame couplers 6352a and 6352b.
The second links 635a and 635b may be rotatably coupled to the filter mounting member connection frames 639a and 639b with reference to second link-first hinge shafts 6351ah and 6351bh that are formed in the first connection frame couplers 6341a and 6341b. The second links 635a and 635b may be rotatably coupled to the cabinet fixing frames 638a and 638b with reference to second link-second hinge shafts 6352ah and 6352bh that are formed in the second fixing frame couplers 6352a and 6352b.
A length of the first links 634a and 634b is longer than a length of the second links 635a and 635b. The first links 634a and 634b may be disposed at an inner side relative to the second links 635a and 635b. A gap G1 between the first connection frame couplers 6241 and 6241b, corresponding to one ends of the first links 634a and 634b, and the second connection frame couplers 6351a and 6351b, corresponding to one ends of the second links 635a and 635b, is greater than a gap G2 between the first fixing frame couplers 6342a and 6342b, corresponding to the other ends of the first links 634a and 634b, and the second fixing frame couplers 6352a and 6352b, corresponding to the other ends of the second links 635a and 635b.
Thus, when the first links 634a and 634b rotates by a predetermined angle in a wide range, the second links 635a and 635b may rotate by an angle greater than the angle of rotation of the first links 634a and 634b and in a range narrower than the range of rotation of the first links 634a and 634b.
The drive transmission links 636a, 636b, 637a, and 637b may be connected to the driving devices 633a and 633b to transfer driving forces of the driving devices 633a and 633b to the first links 634a and 634b. The drive transmission links 636a, 636b, 637a, and 637b may include: motor links 636a and 636b fixedly connected to the driving devices 633a and 633b; and bending links 637a and 637b rotatably connected to the motor links 636a and 636b at one ends and connected to the first links 634a and 634b at the other ends.
The motor links 636 and 636b may be fixedly connected to the driving devices 633a and 633b at one end, and rotatably connected to the bending links 637a and 637b at the other end. The motor links 636a and 636b may include: motor fixing parts 6361a and 6361b fixedly connected to the driving devices 633a and 633b; bending link connecting parts 6362a and 6362b rotatably connected to the bending links 637a and 637b; and motor link bars 6363a and 6363b connecting the motor fixing parts 6361a and 6361b and the bending link connecting parts 6362a and 6362b.
In the motor fixing parts 6361a and 6361b, polygonal shaped fixing grooves 6361ah and 6361bh may be formed at a portion to be fastened to the driving devices 633a and 633b. Since the motor links 636a and 636b is connected to the driving devices 633a and 633b through the fixing grooves 6361ah and 6361bh, the motor links 636a and 636b may be fixedly connected to the driving devices 633a and 633b.
Since the motor links 636a and 636b are fixedly connected to the driving devices 633a and 633b at one end, the motor link bars 6363a and 6363b rotate on the motor fixing parts 6361a and 6361b when the driving devices 633a and 633b are operated. When the driving devices 633a and 633b are operated, the bending link connecting parts 6362a and 6362b of the motor links 636a and 636b rotate with a radius corresponding to the motor link bars 6363a and 6363b. Accordingly, when the driving devices 633a and 633b are operated, the bending links 637a and 637b rotatably connected to the bending link connecting parts 6362a and 6362b move.
The bending links 637a and 637b may have a bent shape of “¬”. The bending links 637a and 637b include: motor link connecting parts 6371a and 6371b rotatably connected to the motor links 636a and 636b; dual link connecting parts 6372a and 6372b rotatably connected to the first links 634a and 634b of the dual links 634a, 634b, 635a, and 635b; and bending link bars 6373a and 6373b having the bending portions 6374a and 6374b and connecting the motor link connecting parts 6371a and 6371b and the dual link connecting parts 6372a and 6372b. The bending portions 6374a and 6374b may have a vertically bent shape. The bending portions 6374a and 6374b are disposed closer to the motor link connecting parts 6371a and 6371b than the dual link connecting parts 6372a and 6372b. In this case, the bending portion having a vertically bent shape may include a shape perfectly vertical or a shape approximately vertical in a range between 80° and 100°.
The bending links 637a and 637b may be rotatably coupled to the motor links 636a and 636b with reference to bending link-first hinge shafts 6371ah and 6371bh that are formed in the motor link connecting parts 6371a and 6371b. The bending links 637a and 637b may be coupled to the first links 634a and 634b with reference to bending link-second hinge shafts 6372ah and 6372bh that are formed in the dual link connecting parts 6372a and 6372b.
The cabinet fixing frames 638a and 638b may be fastened to the mobile member fixing part 1141 formed in the rear parts 114a and 114b of the upper cabinet 11. The cabinet fixing frames 638a and 638b may be inserted into the mobile member fixing part 1141 to be fixed to an additional fastening member (not shown). Fastening holes 6381a and 6381b into which the additional fastening member is inserted may be formed in the cabinet fixing frames 638a and 638b. Since the cabinet fixing frames 638a and 638b are fixed to the upper cabinet 11, the cabinet fixing frames 638a and 638b are prevented from moving even when the driving devices 633a and 633b are operated.
Thus, the position of the first link-second hinge shafts 6342ah and 6342bh formed between the cabinet fixing frames 638a and 638b and the first links 634a and 634b remain fixed even when the driving devices 633a and 633b are operated. In addition, the position of the second link-second hinge shafts 6352ah and 6352bh formed between the cabinet fixing frames 638a and 638b and the second links 635a and 635b remain fixed even when the driving devices 633a and 633b are operated.
The cabinet fixing frames 638a and 638b may be rotatably connected to the dual links 634a, 634b, 635a, and 635b. The cabinet fixing frames 638a and 638b may be rotatably connected to the first links 634a and 634b, and rotatably connected to the second links 635a and 635b. The cabinet fixing frames 638a and 638b may be disposed on an outer side of the rear parts 114a and 114b of the upper cabinet 11. In this case, the outer side may indicate a direction distal from the center line. When the filter mounting members 61a and 61b are disposed in rear of the upper cabinet 11, the cabinet fixing frames 638a and 638b may be disposed at a distance far from the center line than the filter mounting member connection frames 639a and 639b.
The filter mounting member connection frames 639a and 639b may be fastened to the mobile member fastener 611a and 611c of the filter mounting members 61a and 61b. The filter mounting member connection frames 639a and 639b may be fixed to the filter mounting members 61a and 61b and rotatably connected to the dual links 634a, 634b, 635a, and 635b. Thus, when the dual links 634a, 634b, 635a, and 635b move, the filter mounting member connection frames 639a and 639b may move the filter mounting members 61a and 61b.
The filter mounting member connection frames 639a and 639b may include filter mounting member fasteners 6391a and 6391b that are fastened to the filter mounting members 61a and 61b. The filter mounting member fasteners 6391a and 6391b may be formed on both ends of the filter mounting member connection frames 639a and 639b, and connected to the filter mounting members 61a and 61b via an separate fastening member (not shown).
The position of the first link-first hinge shafts 6341ah and 6341bh formed between the filter mounting member connection frames 639a and 639b and the first links 634a and 634b changes when the driving devices 633a and 633b are operated. In addition, the position of the second link-first hinge shafts 6351ah and 6351bh formed between the filter mounting member connection frames 639a and 639b and the second links 635a and 635b changes when the driving devices 633a and 633b are operated.
The position of the filter mounting member connection frames 639a and 639b may change in response to change in position of the first link-first hinge shafts 6341ah and 6341bh and the second link-first hinge shafts 6351ah and 6351bh.
The filter mounting member connection frames 639a and 639b may be rotatably connected to the dual links 634a, 634b, 635a, and 635b. The filter mounting member connection frames 639a and 639b may be rotatably connected to the first links 634a and 634b, and rotatably connected to the second links 635a and 635b. When the filter mounting members 61a and 61b are disposed in rear of the upper cabinet 11, the filter mounting member connection frames 639a and 639b may be disposed at a distance closer to the center line than the cabinet fixing frames 638a and 638b.
Hereinafter, the first lower mobile member 631b and the second lower mobile member 632 will be described primarily about difference from the first upper mobile member 631a and the second upper mobile member 632a, with reference to
Each of the first lower mobile member 631b and the second lower mobile member 632b may include: dual links 634a′, 634b′, 635a′, and 635b′ having different lengths and rotatably connected to the upper cabinet 11 and the filter mounting members 61a and 61b; drive transmission links 636a′, 636b′, 637a′, and 637b′ transferring rotational forces of driving devices 633a′ and 633b′ to the dual links 634a′, 634b′, 635a′, and 635b′; cabinet fixing frames 638a′ and 638b′ fixed to the upper cabinet 11 and rotatably connected to the dual links 634a′, 634b′, 635a′, and 635b′; and filter mounting member connection frames 639a′ and 639b′ fixed to the filter mounting members 61a and 61b and rotatably connected to the dual links 634a′, 634b′, 635a′, and 635b′.
The dual links 634a′, 634b′, 635a′, and 635b′ may include: first links 634a′ and 634b′ rotatably connected to the cabinet fixing frames 638a′ and 638b′ and the filter mounting member connection frames 639a′ and 639b′ and connected to the drive transmission links 636a′, 636b′, 637a′ and 637b′; and a second links 635a′ and 635b′ spaced apart from the first links 634a′ and 634b′ and rotatably connected to the cabinet fixing frames 638a′ and 638b′ and the filter mounting member connection frames 639a′ and 639b′.

<Movement of Mobile Member/Movement of Filter Mounting Member>
Hereinafter, with reference to
The filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d may change in position in relation to the upper cabinet 11 by the first mobile members 631 and 631b and the second mobile members 632a and 632b. By the first mobile members 631 and 631b and the second mobile members 632a and 632b, the filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d may be positioned at a first position P1 in rear of the upper cabinet 11 or at a second position P2 lateral to the upper cabinet 11.
When the filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d are placed at the first position P1, the filter mounting members 61a and 61b are mounted to the upper cabinet 11. When the filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d are placed at the first position P1, air suctioned into the suction port 1143 may pass through the filter modules 62a, 62b, 62c, and 62d.
When the filter mounting members 61a and 61b are placed at the first position P1, the filter mounting member connection frames 639a and 639b and the cabinet fixing frames 638a and 638b may be arranged in parallel with each other. When the filter mounting members 61a and 61b are placed at the first position P1, an angle θ1 formed by a virtual horizontal line H-H′, which passes points rotatably connected to the first links 634a and 634b and points rotatably connected to the second links 635a and 635b in the cabinet fixing frames 638a and 638b, and a straight line, which connects the first link-first hinge shafts 6341ah, 6341bh and the first link-second hinge shafts 6342ah and 6342bh of the first links 634a and 634b, (hereinafter, the angle is referred to as an “angle between the horizontal line H-H′ and the first links 634a and 634b″) corresponds to an acute angle. When the filter mounting members 61a and 61b are placed at the first position P1, an angle θ2 formed by the virtual horizontal line and a straight line, which passes the second link-first hinge shafts 6351ah and 6351bh and the second link-second hinge shafts 6352ah and 6352bh of the second links 635a and 635b, (hereinafter, the angle is referred to as an “angle between the horizontal line H-H′ and the second links 635a and 635b) corresponds to an acute angle.
When the filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d are placed at the second position, the filter mounting members 61a and 61b are released from the upper cabinet 11. When the filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d are placed at the second position, a user may draw the filter modules 62a, 62b, 62c, and 62d from the filter mounting members 61a and 61b or may mount the filter modules 62a, 62b, 62c, and 62d to the filter mounting members 61a and 61b.
When the filter mounting members 61a and 61b are placed at the second position P2, the filter mounting member connection frames 639a and 639b and the cabinet fixing frames 638a and 638b may be disposed to be inclined with respect to each other. When the filter mounting members 61a and 61b are placed at the second position P2, an angle θ1′ between the virtual horizontal line H-H′ and the first links 634a and 634b corresponds to an obtuse angle. When the filter mounting members 61a and 61b are placed at the second position P2, an angle θ2′ between the virtual horizontal line H-H′ and the second links 635a and 635b corresponds to an approximate straight angle.
When the filter mounting members 61a and 61b move from the first position P1 to the second position P2, a variation Δθ2 of the angle formed by the virtual horizontal line and the second links 635a and 635b is greater than a variation of Δθ1 of the angle formed by the virtual horizontal line and the first links 634a and 634b.
When the filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d are placed at the second position, the lateral cover 6222 of the filter modules 62a, 62b, 62c, and 62d is disposed to face forward. When the filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d are placed at the second position, the filter modules 62a, 62b, 62c, and 62d are disposed on an outer side of the lateral parts 112a and 112b of the upper cabinet 11. When the filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d are placed at the second position, the filter mounting member connection frames 639a and 639b are disposed on outer sides of the lateral parts 112a and 112b of the upper cabinet 11. Thus, when the filter mounting members 61a and 61b and the filter modules 62a, 62b, 62c, and 62d are placed at the second position, the filter modules 62a, 62b, 62c, and 62d may be disposed to be separated in a forward direction along the lateral parts 112a and 112b of the upper cabinet 11.
