Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the invention
[0001] The present disclosure relates to an air conditioner, and more particularly, to an air conditioner having discharge ports in a plurality of directions.2. Description of the Related Art
[0002] An air conditioner may supply heat-exchanged air to an indoor space to control the temperature of the indoor space.
[0003] A wall-mounted air conditioner may have discharge ports that open either forward or downward. In a structure having only one discharge port, it is not possible to cover a wide area, making it difficult to provide user comfort. Specifically, when the discharge port is disposed forward, it is difficult to form a direct airflow toward the bottom of the air conditioner. When the discharge port is disposed downward, it is difficult to deliver air to a long distance in the front.
[0004] Korean Patent Publication No. KR 2020-0095936 discloses the structure of an air conditioner in which two discharge ports are formed.
[0005] However, the structure of the above document requires a separate structure for opening and closing each of the two discharge ports. Furthermore, due to the structure, the flow distance of the air discharged forward may be limited.SUMMARY OF THE INVENTION
[0006] An object of the present disclosure is to solve the aforementioned problems and other problems.
[0007] Another object thereof is to provide an air conditioner in which a vane opens and closes some of a plurality of discharge ports, and the flowing air is guided to other discharge ports when the vane is disposed at some of the discharge ports.
[0008] When the vane guides air which is heat-exchanged and flows inside, the temperature difference between the both surfaces of the vane may cause dew to form on one surface. In particular, the possibility of dew is high at both ends of the vane due to the generation of air vortices.
[0009] Another object is to provide an air conditioner that reduces the possibility of dew forming on the surface of the vane.
[0010] In a structure such as a wall-mounted air conditioner, a structure is disclosed in which air is discharged in a fixed direction, that is, forward. However, the heat-exchanged air is not discharged in the left and right directions other than the front.
[0011] Still another object is to provide an air conditioner that discharges heat-exchanged air not only forward but also to the left and right.
[0012] In order to achieve the objects, an air conditioner according to an embodiment of the present disclosure includes: a case having a suction port, a first discharge port disposed on a lower surface, a second discharge port disposed on a front surface, and third discharge ports disposed on both side surfaces; a fan disposed within the case and configured to generate airflow; and a vane configured to open and close the first discharge port.
[0013] Air flowed by the fan sequentially flows through the first discharge port and the second discharge port.
[0014] An inner flow path is formed inside the case, the inner flow path extending from one side of the first discharge port toward the third discharge port.
[0015] The third discharge port may be spaced apart from the first discharge port in a lateral direction.
[0016] The inner flow path laterally from lateral end portions the first discharge port.
[0017] The inner flow path may be formed above the first discharge port.
[0018] A width of the inner flow path formed in a front-rear direction may be equal to or less than half of a width of the first discharge port formed in the front-rear direction.
[0019] A length of the inner flow path extending in a lateral direction may be greater than a width of the inner flow path formed in a front-rear direction.
[0020] A first discharge flow path that is formed below the fan and forwardly directs air flowing downward by the fan, and a second discharge flow path that is formed downstream of the first discharge flow path and directs air flowing above the first discharge port to the second discharge port may be formed inside the case.
[0021] The second discharge flow path may be connected to the inner flow path.
[0022] The second discharge flow path may be formed above the vane when the vane closes the first discharge port.
[0023] The second discharge port may be disposed in front of the second discharge flow path, and the inner flow path may be disposed on the side of the second discharge flow path.
[0024] A width of the second discharge flow path in a lateral direction may be greater than a width of the first discharge flow path in the lateral direction.
[0025] The case may include an upper cover having the suction port formed on an upper surface, and a lower cover disposed below the upper cover.
[0026] The lower cover may include a first discharge cover having the first discharge port formed therein, and a second discharge cover disposed above the first discharge cover and having the second discharge port and the third discharge port formed therein.
[0027] The second discharge port may be formed on one side of a front surface of the second discharge cover, and the inner flow path may be disposed on the rear side of the front surface of the second discharge cover where the second discharge port is not formed.
[0028] The second discharge port of the second discharge cover may be provided with a plurality of front vanes spaced apart in an vertical direction.
[0029] The plurality of front vanes may be disposed to be inclined upward as the vanes move forward.
[0030] A plurality of side vanes spaced apart in the vertical direction may be disposed in the third discharge port of the second discharge cover.
[0031] The plurality of side vanes may be disposed to be inclined upward as the side vanes go outward.
[0032] An upper surface of the vane may form a curved surface inclined downward from a front end.
[0033] The upper surface of the vane may form a curved surface inclined downward from a left or right end.
[0034] The fan may be disposed above the second discharge port and the third discharge port, and send air forward where the first discharge port is disposed.
[0035] The lower surface of the case may be disposed to be inclined forward and upward.
[0036] The vane may be disposed parallel to the lower surface of the case when the first discharge port is closed.
[0037] A plurality of front vanes spaced apart in the vertical direction and inclined forwardly and upwardly in an area where the second discharge port is formed may be disposed on the front surface of the case.
[0038] An inclination angle formed by each of the plurality of front vanes with respect to an imaginary horizontal plane may be greater than an inclination angle formed by the first vane with respect to the imaginary horizontal plane.
[0039] Specific details of other embodiments are included in the detailed description and drawings.
[0040] The air conditioner of the disclosure has one or more of the following advantages.
[0041] First, in the air conditioner of the present disclosure, the discharge ports are formed in a plurality of directions, and thus, it is possible to generate diverse airflows depending on the arrangement of the vanes.
[0042] Second, in the air conditioner of the disclosure, it is possible to prevent dew from forming on the vane surface when the vane is closed.
[0043] Third, in the air conditioner of the disclosure, it is possible to provide heat-exchanged air in the left and right directions, rather than just the forward or downward direction. Therefore, it is possible to rapidly generate air circulation by distributing heat-exchanged air in various directions.
[0044] Effects of the present disclosure are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The lower cover 30 may be coupled to the upper cover 20.
[0056] The lower cover 30 includes a first discharge cover 32 (refer to FIG. 2) forming the first discharge port 14 and a second discharge cover 34 disposed above the first discharge cover 32.
[0057] The first discharge cover 32 forms the lower surface of the case 10.
[0058] The second discharge cover 34 is disposed between the first discharge cover 32 and the upper cover 20. The second discharge cover 34 is coupled to the first discharge cover 32. The first discharge cover 32 and the second discharge cover 34 are coupled by a fusion method.
[0059] Referring to FIG. 2, the internal configuration and the structure of case of the air conditioner are described.
[0060] The air conditioner has a fan 40 disposed inside the case 10. The fan 40 is disposed below the suction port 12. The fan 40 rotates and sends air downward. The fan 40 is disposed above the first discharge port 14. The fan 40 rotates and sends air downward in the forward direction.
[0061] The fan 40 may use a cross-flow fan.
[0062] The air conditioner includes a heat exchanger 42 disposed inside the case 10. The heat exchanger 42 is disposed above the fan 40. Therefore, air coming down from the suction port 12 may flow to the fan 40 through the heat exchanger 42.
[0063] The heat exchanger 42 is disposed below the suction port 12.
[0064] The air conditioner includes an inner body 44 disposed inside the case 10. The inner body 44 is disposed rearward inside the case 10. One side of the inner body 44 may support the heat exchanger 42. The inner body 44 may send air flowing downward by the fan 40 to the first discharge port 14.

[0069] The air conditioner includes a stabilizer 50 disposed inside the case 10 and spaced apart from the inner body 44.
[0070] The stabilizer 50 is disposed above the first discharge port 14. A discharge flow path 70 is formed between the stabilizer 50 and the inner body 44 to send air flowing by the fan 40 to the first discharge port 14.
[0071] The air conditioner includes a first vane (or "vane") 52 that opens and closes the first discharge port 14. The first vane 52 may open or close the first discharge port 14 depending on the arrangement.
[0072] When the first vane 52 closes the first discharge port 14, the first vane 52 may guide the air flowing through the discharge flow path 70 to the second discharge port 16. When the first vane 52 closes the first discharge port 14, the first vane 52 extends forward from the inner guider 46.
[0073] The air conditioner includes a second vane 54 disposed inside the case 10. The second vane 54 may be formed to have a shorter length than the first vane 52. The arrangement of the second vane 54 may be changed in conjunction with the first vane 52.
[0074] The air conditioner may include a link module 56 that changes the arrangement of the first vane 52 and the second vane 54. The link module 56 changes the arrangement by a link motor 64 (refer to FIG. 3) and may change the arrangement of the first vane 52 and the second vane 54.
[0075] The link module 56 is connected to the link motor and includes a drive link 58 connected to the first vane 52, and a first link 60 connecting the case 10 and the first vane 52. The link module 56 includes a second link 62 that connects the drive link 58 and the second vane 54.
[0076] One side of the second vane 54 may be rotatably connected to the case 10.
[0077] The case 10 includes the upper cover 20 forming a suction port 12. The front cover 24 is disposed on the front surface of the upper cover 20. The separate intake grill 22 may be disposed on the suction port 12 formed on the upper portion of the upper cover 20.
[0078] The lower cover 30 may be disposed under the upper cover 20. The lower cover 30 is connected to the upper cover 20.
[0079] The lower cover 30 forms the first discharge port 14 and includes the first discharge cover 32 disposed on the lower surface. The first discharge cover 32 may be coupled to one side of the inner body 44. The first discharge cover 32 may have a structure that is hooked to one side of the upper cover 20.
[0080] The lower cover 30 includes the second discharge cover 34 disposed above the first discharge cover 32.
[0081] The second discharge port 16 is formed on the front surface of the second discharge cover 34. The third discharge port 18 is formed on the side surface of the second discharge cover 34.
[0082] The second discharge port 16 is formed on one side of the front surface of the second discharge cover 34, and an inner flow path 76 is disposed on the rear side of the front surface where the second discharge port 16 is not formed.
[0083] Referring to FIG. 3, the arrangement of the discharge flow path, the inner flow path, and the arrangement of the second discharge port and the third discharge port are described.
[0084] The discharge flow path 70 is formed inside the case 10 to send air flowing by the fan 40 to the first discharge port 14. The discharge flow path 70 includes a first discharge flow path 72 disposed below the fan 40, and a second discharge flow path 74 disposed downstream of the first discharge flow path 72 and having a width wider than the width of the first discharge flow path 72 in the lateral direction.
[0085] The width of the first discharge flow path 72 formed in the lateral direction may be formed to a size corresponding to the width of the fan 40 in the lateral direction.
[0086] The second discharge flow path 74 is disposed downstream of the first discharge flow path 72. The second discharge flow path 74 is disposed in front of the first discharge flow path 72. The first discharge port 14 is disposed below the second discharge flow path 74. The length of the first discharge port 14 formed in the lateral direction may be formed longer than the length of the fan 40 formed in the lateral direction.
[0087] The first vane 52 and the second vane 54 are disposed in the second discharge flow path 74. The second discharge flow path 74 is connected to the inner flow path 76.
[0088] The second discharge flow path 74 is disposed in front of the first discharge flow path 72 and has a structure extending in one direction of the first discharge flow path 72. That is, the second discharge flow path 74 may have a structure that becomes longer in one of the left or right directions in front of the first discharge flow path 72.
[0089] The second discharge flow path 74 may be formed above the first discharge port 14 when the first vane 52 closes the first discharge port 14.
[0090] The second discharge port 16 is disposed in front of the second discharge flow path 74. Therefore, a length 14W of the first discharge port 14 formed in the lateral direction may be the same as a length 16W of the second discharge port 16 formed in the lateral direction.
[0091] That is, the length of each of the first discharge port 14 and the second discharge port 16 formed in the lateral direction may be formed longer than the length of the first discharge flow path 72 formed in the lateral direction.
[0092] The third discharge port 18 is formed on both side surfaces of the case 10. The third discharge port 18 may be formed at a position spaced apart from the first discharge port 14 in the lateral direction. The third discharge port 18 may be formed at a position spaced apart from the second discharge port 16 in the lateral direction.
[0093] Inside the case 10, the inner flow path 76 may be formed that extends in the lateral direction from the front of the first discharge port 14 and is a passage through which air flows. The inner flow path 76 extends to the third discharge port 18.
[0094] The inner flow path 76 includes a first inner flow path 76a extending in one direction of the first discharge port 14 and a second inner flow path 76b extending in the other direction of the first discharge port 14.
[0095] The second discharge flow path 74 extends from the front of the first discharge flow path 72 toward the second inner flow path 76b.
[0096] A length 76L of the inner flow path 76 formed in the lateral direction may be formed longer than a width 76W of the inner flow path 76 formed in the front-rear direction.
[0097] The length 76L of the inner flow path 76 formed in the lateral direction may be formed to be at least twice the width 76W of the inner flow path 76 formed in the front-rear direction.
[0098] A portion of the air flowing over the first vane 52 flows through the inner flow path 76. The larger the space of the inner flow path 76, the better the performance of improving the vortex phenomenon occurring in the air flowing over the first vane 52. However, when the width 76W formed in the front-rear direction is too large, the amount of air flowing to the second discharge port 16 may be reduced.
[0099] Accordingly, the width 76W of the inner flow path 76 formed in the front-rear direction is formed smaller than the length 76L of the inner flow path 76 formed in the lateral direction.
[0100] The width 76W of the inner flow path 76 formed in the front-rear direction is formed smaller than the length 14L of the first discharge port 14 formed in the front-rear direction. The width 76W of the inner flow path 76 formed in the front-rear direction may be formed to be equal to or less than half of the length 14L of the first discharge port 14 formed in the front-rear direction.
[0101] The inner flow path 76 is formed on the side of the first discharge port 14. The second discharge port 16 is disposed in front of the first discharge port 14. In addition, the length of the second discharge port 16 formed in the lateral direction may correspond to the length of the first discharge port 14 formed in the lateral direction.
[0102] Therefore, air flowing forward along the discharge flow path 70 in a state where the first vane 52 closes the first discharge port 14 may flow to the second discharge port 16.
[0103] However, since the inner flow path 76 is formed laterally at the front end of the first vane 52, the air that is driven to the left and right sides of the first vane 52 may flow to the inner flow path 76. Therefore, it is possible to prevent the air from stagnating on the left and right sides of the first vane 52. This can prevent the condensation phenomenon that occurs in the first vane 52.
[0104] Referring to FIG. 4, the front vane and the surrounding configuration disposed in the second discharge port 16 are described.
[0105] The first discharge flow path 72 may have a shape inclined downward. The second discharge flow path 74 is formed above the first discharge port 14.
[0106] The air flowing from the first discharge flow path 72 to the second discharge flow path 74 may flow to the first discharge port 14. In addition, the air flowing from the first discharge flow path 72 to the second discharge flow path 74 may flow along the upper surface of the first vane 52. The air flowing along the upper surface of the first vane 52 may flow to the second discharge port 16 or the third discharge port 18.
[0107] The second discharge flow path 74 may be connected to the inner flow path 76 at the front thereof. The second discharge flow path 74 and the inner flow path 76 may be disposed at an angle.
[0108] The first vane 52 may be disposed at the first discharge port 14. The first vane 52 may be disposed at the first discharge port 14 to close the first discharge port 14. The first vane 52 may open the first discharge port 14 while descending from the first discharge port 14.
[0109] The lower surface of the case 10 may form an upwardly inclined surface as the lower surface goes forward. When the first vane 52 closes the first discharge port 14, the first vane 52 may be disposed parallel to the lower surface of the case 10.
[0110] When the first vane 52 closes the first discharge port 14, the first vane 52 may be disposed in a forwardly inclined form.
[0111] The front vane 36 is disposed in the second discharge port 16. A plurality of front vanes 36 are disposed in the second discharge port 16. The plurality of front vanes 36 are disposed spaced apart from each other in the vertical direction.
[0112] A plurality of front vanes 36 may be disposed to be inclined upwards as the front vanes 36 go forward. The inclination angle θ1 (or "inclination angle of the front vane") formed by the front vanes 36 with respect to an imaginary horizontal plane may be formed to be greater than the inclination angle θ2 (or "inclination angle of the first vane") formed by the first vane 52 with the first discharge port 14 closed with respect to an imaginary horizontal plane.
[0113] The length 36L of each of the plurality of front vanes 36 extending in the front-rear direction is formed longer than an interval D1 at which the plurality of front vanes 36 are spaced apart in the vertical direction.
[0114] The upper surface of the first vane 52 may form an inclined surface inclined downward from the front end. The upper surface of the first vane 52 may form a curved surface inclined downward from the front end.
[0115] The inner flow path 76 and the third discharge port 18 are disposed on one side of the front portion of the first discharge port 14. The width 76W of the inner flow path 76 formed in the front-rear direction is smaller than half the length 52L of the first vane 52 formed in the front-rear direction.
[0116] The width 76W at which the inner flow path 76 is formed in the front-rear direction is formed smaller than the height 76H at which the inner flow path 76 is formed in the vertical direction.
[0117] The thickness of each front vane 36 formed in the vertical direction becomes smaller as the front vane 36 goes from the rear to the front.
[0118] Referring to FIG. 5, the side vane and the surrounding configuration disposed in the third discharge port are described.
[0119] The inner flow path 76 extends laterally from the first discharge port 14. The third discharge port 18 is formed on the side surface of the case 10. The third discharge port 18 is disposed at a certain distance from the first discharge port 14 in the lateral direction.
[0120] The inner flow path 76 guides the air flowing above the first vane 52 to the third discharge port 18.
[0121] The length 76L of the inner flow path 76 extending in the lateral direction is formed longer than the height 76H of the inner flow path 76 formed in the vertical direction.
[0122] The upper surface of the first vane 52 forms a downwardly inclined surface at the left or right end. The upper surface of the first vane 52 forms a downwardly inclined curved surface at the left or right end.
[0123] A side vane 38 is disposed in the third discharge port 18. A plurality of side vanes 38 spaced apart in the vertical direction are disposed in the third discharge port 18.
[0124] The side vane 38 forms an inclined surface extending upwards as the side vane goes outward. The side vane 38 forms an inclined surface that is inclined upward.
[0125] The side vane 38 may have a length equal to or greater than a certain length to guide the air flow. The length 38L of each of the side vanes 38 extending in the lateral direction is formed longer than the interval D2 at which the plurality of side vanes 38 are spaced apart in the vertical direction.
[0126] The length 18H of the third discharge port 18 formed in the vertical direction is longer than the length 38L of the side vane 38 extending in the lateral direction.
[0127] Referring to FIGS. 6 and 7, the flow of air according to the rotation of the fan is explained.
[0128] As the fan 40 rotates, air introduced into the suction port 12 flows to the discharge port 14, 16, and 18, and air flows below the fan 40 due to the rotation of the fan 40.
[0129] That is, as illustrated in FIG. 6, air flows into the first discharge flow path 72 formed by the stabilizer 50 and the inner body 44 by the rotation of the fan 40.
[0130] The air flowing through the first discharge flow path 72 flows through the second discharge flow path 74 formed above the first vane 52. In a state where the first discharge port 14 is closed by the first vane 52, the air flows through the second discharge flow path 74 formed above the first vane 52.
[0131] Air flows forward of the second discharge flow path 74. Therefore, most of the air is discharged through the second discharge port 16 disposed in front of the second discharge flow path 74.
[0132] However, the air flowing along both sides of the second discharge flow path 74 may form vortices due to friction with the inner wall surface, or the like. In this way, the air flowing along both sides of the second discharge flow path 74 may flow into the inner flow path 76 formed in the lateral direction at the front of the first vane 52.
[0133] A portion of the air flowing through the second discharge flow path 74 flows into the inner flow path 76 and is discharged through the third discharge port 18. The inner flow path 76 can improve the flow of air stagnant above the left and right sides of the first vane 52. In other words, it is possible to remove condensation formed at the left and right ends of the first vane 52.
[0134] Although the preferred embodiments of the disclosure have been illustrated and described above, the disclosure is not limited to the specific embodiments described above, and various modifications may be made by a person having ordinary skill in the art to which the present disclosure pertains without departing from the concept of the disclosure as claimed in the claims, and such modifications should not be understood individually from the technical idea or prospect of the disclosure.
