[0002] An air conditioner is a device that adjusts the temperature of indoor air to a temperature set by a user, and is a device that cools and heats indoor air according to the principle of a refrigeration cycle. In particular, an air conditioner in which an indoor unit is vertically installed in an indoor space is called a floor-standing air conditioner, an air conditioner in which an indoor unit is installed on a wall in a room is called a wall-mounted air conditioner, and an air conditioner in which an indoor unit is installed on a ceiling in a room is called a ceiling-mounted air conditioner.

[0003] Korean Patent No. 10-2149736 discloses an "indoor unit of an air conditioner", which includes: a main body having a suction port and a discharge port; a heat exchanger that cools indoor air inhaled through the suction port; a cross-flow fan that inhales indoor air through the suction port and discharges cooled air to the discharge port; and blades disposed at the discharge port to control the direction of the discharged air flow, and both ends thereof are formed sharply; a heat insulating member is provided between the inner surface and the outer surface of the blades.

[0004] In the above-mentioned conventional air conditioner, since heat insulating members are not disposed at both ends of the blades, there is a problem of dew condensation occurring at both ends of the blades due to the temperature difference between the inner surface and the outer surface.

[0005] In addition, in the above-mentioned conventional air conditioner, since the space formed inside both ends of the blades is not uniform, there is a problem that it is difficult to dispose a heat insulating member having low stretchability.

[0088] Refer to Figure 1 Describe the air conditioner 1.

[0089] The air conditioner 1 may include a housing 10 formed with a suction port 11 and a discharge port 12. The housing 10 may form the outer shape of the air conditioner 1. The housing 10 may extend long. The housing 10 may form an internal space for accommodating a refrigeration cycle device.

[0090] The housing 10 may include a front wall 102 forming the front. The front wall 102 may face the indoor space. The front wall 102 may face forward. The housing 10 may include side walls 104 forming the sides. The side walls 104 may cover the sides of the housing 10. The side walls 104 may be connected to the front wall 102. The side walls 104 may include a pair of side walls 104 bent from the front wall 102.

[0091] The suction port 11 may be formed in the housing 10. The suction port 11 may be formed on one surface of the housing 10. For example, the suction port 11 may open on the top surface of the housing 10. The suction port 11 may open upward in the housing 10. Thus, indoor air may flow into the interior of the housing 10 through the suction port 11.

[0092] The discharge port 12 may be formed in the housing 10. The discharge port 12 may be formed on the other surface of the housing 10. For example, the discharge port 12 may include a first discharge port 12a formed on the front wall 102 of the housing 10. The discharge port 12 may extend long. For example, the first discharge port 12a opening forward on the front wall 102 of the housing 10 may extend long in the left - right direction.

[0093] The air inside the housing 10 may be discharged into the indoor space through the discharge port 12. In addition, the air flowing in through the suction port 11 may be discharged through the discharge port 12. For example, the air inside the housing 10 may be discharged forward of the air conditioner 1 through the first discharge port 12a.

[0094] The air conditioner 1 may include a filter 20 disposed at the suction port 11. The filter 20 may be formed in a shape corresponding to the shape of the suction port 11. The filter 20 may purify the air flowing into the suction port 11.

[0098] Refer to Figure 2 , and describe the components disposed inside the air conditioner 1. The air conditioner 1 may include an indoor heat exchanger 16, a blower fan 17, and a guiding structure forming a discharge flow path 180.

[0099] The air conditioner 1 may include an indoor heat exchanger 16 disposed inside the housing 10. The indoor heat exchanger 16 may exchange heat between the air inside the housing 10 and the refrigerant. The indoor heat exchanger 16 may exchange heat between the air flowing in through the suction port 11 and the refrigerant. The air heat-exchanged by the indoor heat exchanger 16 may be supplied to the indoor space through the discharge port 12. The indoor heat exchanger 16 may exchange heat between the air flow formed by the blower fan 17 and the refrigerant. The indoor heat exchanger 16 may function as an evaporator or a condenser. For example, the indoor heat exchanger 16 may function as an evaporator to supply cold air to the indoor space. For example, the indoor heat exchanger 16 may function as a condenser to supply warm air to the indoor space.

[0100] The air conditioner 1 may include a blower fan 17 disposed inside the housing 10. The blower fan 17 may form an air flow flowing from the suction port 11 to the discharge port 12. The air flow formed by the blower fan 17 may exchange heat with the refrigerant in the indoor heat exchanger 16.

[0101] The blower fan 17 may be disposed adjacent to the indoor heat exchanger 16. For example, the blower fan 17 may be located at a position closer to the downstream side in the air flow direction than the indoor heat exchanger 16. However, this is not limited thereto, and the blower fan 17 may also be located at a position closer to the upstream side in the air flow direction than the indoor heat exchanger 16.

[0102] In the housing 10, a discharge flow path 180 through which an air flow formed by the air supply fan 17 flows may be formed. The discharge flow path 180 may be located at a position closer to the downstream side in the air flow direction than the air supply fan 17. The discharge flow path 180 may be located at a position closer to the downstream side in the air flow direction than the indoor heat exchanger 16. The air flow that has passed through the indoor heat exchanger 16 or the air supply fan 17 may flow through the discharge flow path 180 toward the discharge port 12. The discharge flow path 180 may be connected to the discharge port 12.

[0103] The air conditioner 1 may include a front guide portion 184 that forms the discharge flow path 180. The front guide portion 184 may be disposed inside the housing 10. The front guide portion 184 may separate the indoor heat exchanger 16 and the discharge flow path 180. The front guide portion 184 can prevent air that has not passed through the indoor heat exchanger 16 from flowing into the discharge flow path 180. The front guide portion 184 may be disposed below the indoor heat exchanger 16.

[0104] The front guide portion 184 may be disposed adjacent to the discharge port 12. The front guide portion 184 may extend from the air supply fan 17 toward the discharge port 12. For example, the front guide portion 184 may extend from the air supply fan 17 toward the first discharge port 12a. The front guide portion 184 may extend in a bent manner. Thereby, the discharged air flow can flow smoothly.

[0105] The air conditioner 1 may include an intermediate guide portion 181 spaced apart from the front guide portion 184. The intermediate guide portion 181 may be disposed inside the housing 10. The air supply fan 17 may be disposed between the intermediate guide portion 181 and the front guide portion 184. The intermediate guide portion 181 may guide the air flow that has passed through the air supply fan 17 toward the discharge flow path 180. For example, the intermediate guide portion 181 is spaced rearward from the front guide portion 184, and the air supply fan 17 may be located between the front guide portion 184 and the intermediate guide portion 181 and form an air flow. The intermediate guide portion 181 may extend in a bent manner along the rotation direction of the air supply fan 17.

[0106] The air conditioner 1 may include a rear guide portion 182 that forms the discharge flow path 180. The discharge flow path 180 may be formed between the front guide portion 184 and the rear guide portion 182. The rear guide portion 182 may be spaced apart from the front guide portion 184. For example, the rear guide portion 182 may be spaced rearward from the front guide portion 184.

[0107] The rear guide portion 182 may be connected to the intermediate guide portion 181. The rear guide portion 182 may extend from the intermediate guide portion 181 toward the discharge port 12. For example, the rear guide portion 182 may extend from the intermediate guide portion 181 toward a second discharge port 12b (not shown) described later. The rear guide portion 182 may be disposed below the intermediate guide portion 181. The rear guide portion 182 may be disposed below the air supply fan 17. The rear guide portion 182 may be disposed adjacent to the discharge port 12.

[0108] The discharge port 12 may include a second discharge port 12b (not shown) that opens downward in the housing 10. The second discharge port 12b (not shown) may be formed on the lower sidewall 106 of the housing 10. The second discharge port 12b (not shown) may be adjacent to the first discharge port 12a. For example, the first discharge port 12a may open forward on the front wall 102 of the housing 10, and the second discharge port 12b (not shown) may open downward on the lower sidewall 106 of the housing 10. Thus, the discharged air can be discharged forward and downward through the first discharge port 12a and the second discharge port 12b (not shown), respectively.

[0109] The blade may include a second blade 15 disposed at the second discharge port 12b (not shown). The second blade 15 may open or close the second discharge port 12b (not shown).

For example, the guide module 30 may guide the flow direction of the air flow flowing in the discharge flow path 180 to the left and right directions. Thus, the direction of the air flow discharged into the indoor space can be controlled more precisely.

[0111] The guide module 30 may be coupled to the rear guide portion 182. The guide module 30 may be disposed between the rear guide portion 182 and the front guide portion 184. The plurality of guide vanes 32, 34 (refer to Figure 5 ) may move in the left and right directions. The guide module 30 may be located at a position closer to the downstream side in the air flow direction than the air supply fan 17. In the air flow path, the guide module 30 may be located between the discharge port 12 and the air supply fan 17.

That is, based on the second fan holder 61b, a first internal space in which the air supply fan 17 and the indoor heat exchanger 16 are arranged may be formed on one side, and a second internal space in which the electrical unit 50 is arranged may be formed on the other side.

[0124] The rear guide part 182 may be arranged in the first internal space. The rear guide part 182 may be coupled to the chassis 60.

[0125] The guide module 30 may be arranged in the first internal space. The guide module 30 may be coupled to the rear guide part 182.

[0126] Refer to Figure 5 Describe the guide module 30.

[0127] The guide module 30 may include a plurality of guide vanes 32, 34 arranged in the discharge flow path 180. The plurality of guide vanes 32, 34 may be arranged in a row. The plurality of guide vanes 32, 34 may be spaced apart from each other. The plurality of guide vanes 32, 34 may be arranged in a direction crossing the flow direction of the air flow toward the discharge port 12. For example, the air flow may flow in the vertical direction, and the plurality of guide vanes 32, 34 may be arranged in the horizontal direction.

[0128] The guide vanes 32, 34 may include a pair of first guide vanes 32 spaced apart from each other. The pair of first guide vanes 32 may be arranged at the edge of the guide module 30. The pair of first guide vanes 32 may be arranged close to the inner wall forming the discharge flow path 180. The pair of first guide vanes 32 may be respectively arranged at one end and the other end in the longitudinal direction of the guide module 30. The pair of first guide vanes 32 may be respectively arranged on one side and the other side in the direction in which the plurality of guide vanes 32, 34 are arranged. The first guide vane 32 may form the edge of the plurality of guide vanes 32, 34.

[0129] A plurality of guide vanes 32, 34 may include a plurality of second guide vanes 34 arranged between a pair of first guide vanes 32. The plurality of second guide vanes 34 may be arranged in a direction in which the pair of first guide vanes 32 are separated. That is, the direction in which the plurality of second guide vanes 34 are arranged and the direction in which the pair of first guide vanes 32 are separated may be parallel.

[0130] The guide module 30 may include a coupling panel 31 coupled to the plurality of guide vanes 32, 34. The coupling panel 31 may extend long. The coupling panel 31 may be coupled to the discharge flow path 180. A pair of first guide vanes 32 may be respectively coupled to one end and the other end of the coupling panel 31. The plurality of second guide vanes 34 may be coupled to the coupling panel 31 between the pair of first guide vanes 32.

[0131] The guide module 30 may include a link 36 coupled to the plurality of guide vanes 32, 34. The link 36 may extend long. The link 36 may include a link panel 364 and a link stick 362 extending long from the link panel 364. The width of the link panel 364 may be wider than the width of the link stick 362. The length of the link panel 364 may be shorter than the length of the link stick 362.

[0132] A pair of first guide vanes 32 may be respectively coupled to one end and the other end in the longitudinal direction of the link stick 362. The plurality of second guide vanes 34 may be coupled to the link stick 362 and the link panel 364. The plurality of guide vanes 32, 34 may move integrally with the link 36. For example, when the link 36 moves in the left - right direction, the plurality of guide vanes 32, 34 may move in the left - right direction. Thus, the flow direction of the air flow flowing in the discharge flow path 180 can be adjusted.

[0133] Refer to Figure 6 to illustrate a pair of first guide vanes 32.

[0134] The first guide vane 32 may include a fixing portion 322 coupled to the coupling panel 31. The fixing portion 322 may be fixed to the coupling panel 31. The width of the fixing portion 322 may increase as it gets closer to the flow direction of the discharged air flow.

[0135] The first guide vane 32 may include a movable portion 326 to which the link 36 is coupled. The movable portion 326 may be separated from the fixing portion 322. The movable portion 326 may move. The movable portion 326 may move in a direction crossing the flow direction of the discharged air flow. For example, the movable portion 326 may move in the left - right direction through the link 36 coupled thereto. The width of the movable portion 326 may be larger than the width of the fixing portion 322.

[0136] The first guide vane 32 may include a connecting portion 324 that connects a movable portion 326 and a fixed portion 322. The connecting portion 324 may be located between the movable portion 326 and the fixed portion 322. The width of the connecting portion 324 may gradually increase as it approaches the movable portion 326 from the fixed portion 322.

[0137] The thickness of the connecting portion 324 may be thinner than the thickness of the fixed portion 322. The thickness of the connecting portion 324 may be thinner than the thickness of the movable portion 326. Accordingly, the flexibility of the connecting portion 324 may be greater than the flexibility of the fixed portion 322 or the movable portion 326.

[0138] The connecting portion 324 may be connected to the movable movable portion 326 and bent. For example, the connecting portion 324 may be bent along with the movable portion 326 that moves in the left - right direction.

[0139] The connecting portion 324 may include: a first connecting portion 3242 that connects the movable portion 326 and the fixed portion 322; and a second connecting portion 3244 that is located between the movable portion 326 and the fixed portion 322. The second connecting portion 3244 may extend from the movable portion 326. The second connecting portion 3244 may extend from the movable portion 326 toward the fixed portion 322 and may be spaced apart from the fixed portion 322. That is, the second connecting portion 3244 may not be connected to the fixed portion 322. Accordingly, the second connecting portion 3244 may move integrally with the movement of the movable portion 326.

[0140] The second connecting portion 3244 may include a bent portion 3245 that is bent toward the edge of the fixed portion 322. That is, the edge of the second connecting portion 3244 toward the fixed portion 322 may be formed in a curved shape. Accordingly, the discharged air flow can smoothly pass through the second connecting portion 3244, thereby reducing noise.

[0141] The width of the connecting portion 324 may increase as it gets closer to the movable portion 326 from the fixed portion 322. The width of the second connecting portion 3244 may increase as it gets closer to the movable portion 326 from the fixed portion 322.

[0142] The first connecting portion 3242 and the second connecting portion 3244 may be spaced apart from each other. The connecting portion 324 may include a slit 3240 formed between the first connecting portion 3242 and the second connecting portion 3244. The slit 3240 may extend longitudinally. The slit 3240 may start extending from the spaced - apart interval between the second connecting portion 3244 and the fixed portion 322. By forming the slit 3240 between the first connecting portion 3242 and the second connecting portion 3244, the first connecting portion 3242 that moves while adhering to the fixed portion 322 and the second connecting portion 3244 that moves freely can move independently without interfering with each other.

[0143] The movable part 326 may include a first movable part 3261 directly connected to the connecting part and a second movable part 3262 combined with the connecting rod 36. The first movable part 3261 may connect the second movable part 3262 and the connecting part 324. The first connecting part 3242 and the second connecting part 3244 may be connected to the first movable part 3261. The first connecting part 3242 may connect the first movable part 3261 and the fixed part 322. The thickness of the first movable part 3261 may gradually become thicker as it approaches the second movable part 3262 from the first connecting part 3242. Due to the thickness change of the first movable part 3261, a step may not be formed between the connecting part 324 and the movable part 326. Thus, the airflow flowing along the guide vanes 32, 34 may flow smoothly.

[0144] The first guide vane 32 may include a communication hole 3260 formed in the movable part 326. The communication hole 3260 may be a through hole formed through the first guide vane 32. The communication hole 3260 may be formed in a direction intersecting the flow direction of the discharged airflow. The communication hole 3260 may be formed in the direction in which a plurality of guide vanes 32, 34 are arranged. Thus, the airflow flowing along the first guide vane 32 may flow through the first guide vane 32.

[0145] The communication hole 3260 may include a plurality of communication holes 3260 formed in the movable part 326. The plurality of communication holes 3260 may be arranged in a direction intersecting the flow direction of the discharged airflow. The plurality of communication holes 3260 may be arranged in a direction intersecting the direction in which a plurality of guide vanes 32, 34 are arranged. The plurality of communication holes 3260 may be arranged in the width direction of the movable part 326. For example, the plurality of communication holes 3260 may be arranged in the vertical direction.

[0146] The communication hole 3260 may extend long. The communication hole 3260 may extend long in a direction parallel to the flow direction of the discharged airflow. The communication hole 3260 may extend long in a direction intersecting the width direction of the movable part 326. For example, the communication hole 3260 may extend long in the vertical direction or the front-rear direction. Thus, the airflow flowing in the discharge flow path may flow smoothly through the communication hole 3260.

[0147] The movable part 326 may include a reinforcing part 3264 formed between a plurality of communication holes 3260. The reinforcing part 3264 may partition the plurality of communication holes 3260. The reinforcing part 3264 may extend longitudinally. The reinforcing part 3264 may extend in a direction parallel to the flow direction of the discharged air flow. For example, the reinforcing part 3264 may extend longitudinally in the vertical direction or the horizontal direction. The reinforcing part 3264 may include a plurality of reinforcing parts 3264 formed between the plurality of communication holes 3260. Since the reinforcing part 3264 is formed by extending in the flow direction of the discharged air flow between the communication holes 3260, the rigidity of the movable part 326 can be improved.

[0148] The first guide vane 32 may include a coupling slot 3263 for arranging the link 36. The coupling slot 3263 may be formed in the movable part 326. The coupling slot 3263 may be a through hole formed in the first guide vane 32. The coupling slot 3263 may be formed in a direction intersecting the flow direction of the discharged air flow. The coupling slot 3263 may extend longitudinally in a direction parallel to the flow direction of the discharged air flow. Thus, the discharged air flow can also flow through the first guide vane 32 through the coupling slot 3263.

[0149] The coupling slot 3263 may be aligned with the plurality of communication holes 3260. For example, the coupling slot 3263 and the plurality of communication holes 3260 may be formed in a line in the movable part 326 in the vertical direction or the front-rear direction.

[0150] The coupling panel 31 may include a hook 312 for coupling with the discharge flow path 180. For example, the coupling panel 31 may be hook-coupled to the rear guide part 182 forming the discharge flow path 180.

[0151] Refer to Figure 7 Describe the second guide vane 34.

[0152] The second guide vane 34 may include a fixing part 342 coupled to the coupling panel 31. The fixing part 342 may be fixed to the coupling panel 31. The width of the fixing part 342 may increase as it gets closer to the flow direction of the discharged air flow.

[0153] The second guide vane 34 may include a movable part 346 for coupling the link 36. The movable part 346 may be separated from the fixing part 342. The movable part 346 may move. The movable part 346 may move in a direction intersecting the flow direction of the discharged air flow. For example, the movable part 346 may move in the left-right direction through the link 36 coupled thereto. The width of the movable part 346 may be larger than the width of the fixing part 342.

[0154] The second guide vane 34 may include a connecting portion 344 that connects the movable portion 346 and the fixed portion 342. The connecting portion 344 may be located between the movable portion 346 and the fixed portion 342. The width of the connecting portion 344 may gradually increase as it approaches the movable portion 346 from the fixed portion 342.

[0155] The thickness of the connecting portion 344 may be thinner than the thickness of the fixed portion 342. The thickness of the connecting portion 344 may be thinner than the thickness of the movable portion 346. Accordingly, the flexibility of the connecting portion 344 may be greater than the flexibility of the fixed portion 342 or the movable portion 346.

[0156] The connecting portion 344 may be connected to and bent with the movable movable portion 346. For example, the connecting portion 344 may be bent as the movable portion 346 moves in the left - right direction.

[0157] The connecting portion 344 may include: a first connecting portion 3442 that connects the movable portion 346 and the fixed portion 342; and a second connecting portion 3444 that is located between the movable portion 346 and the fixed portion 342. The second connecting portion 3444 may extend from the movable portion 346. The second connecting portion 3444 may be connected from the movable portion 346 toward the fixed portion 342 and may be spaced apart from the fixed portion 342. That is, the second connecting portion 3444 may not be connected to the fixed portion 342. Accordingly, the second connecting portion 3444 may move more freely as the movable portion 346 moves.

[0158] The second connecting portion 3444 may include a bent portion 3245 that is formed to bend toward the edge of the fixed portion 342. That is, the edge of the second connecting portion 3444 toward the fixed portion 342 may be formed in a curved shape. Accordingly, the discharged air flow can smoothly pass through the second connecting portion 3444, and the generated noise can be reduced.

[0159] The width of the connecting portion 344 may increase as it gets closer to the movable portion 346 from the fixed portion 342. The width of the second connecting portion 3444 may increase as it gets closer to the movable portion 346 from the fixed portion 342.

[0160] The first connecting portion 3442 and the second connecting portion 3444 may be spaced apart from each other. The connecting portion 344 may include a slit 3440 formed between the first connecting portion 3442 and the second connecting portion 3444. The slit 3440 may extend long. The slit 3440 may start to extend from the spaced - apart interval between the second connecting portion 3444 and the fixed portion 342. By forming the slit 3440 between the first connecting portion 3442 and the second connecting portion 3444, the first connecting portion 3442 that moves attached to the fixed portion 342 and the second connecting portion 3444 that moves freely can move independently without interfering with each other.

[0161] The movable part 346 may include a first movable part 3461 directly connected to the connecting part and a second movable part 3462 combined with the connecting rod 36. The first movable part 3461 may connect the second movable part 3462 and the connecting part 344. The first connecting part 3442 and the second connecting part 3444 may be connected to the first movable part 3461. The first connecting part 3442 may connect the first movable part 3461 and the fixed part 342. The thickness of the first movable part 3461 may gradually become thicker as it approaches the second movable part 3462 from the first connecting part 3442. Due to the thickness change of the first movable part 3461, no step may be formed between the connecting part 344 and the movable part 346. Thus, the airflow flowing along the guide vanes 32, 34 may flow smoothly.

[0162] The second guide vane 34 may include a coupling slot 3463 for arranging the connecting rod 36. The coupling slot 3463 may be formed in the movable part 346. The coupling slot 3463 may be a through hole formed in the second guide vane 34. The coupling slot 3463 may be formed in a direction intersecting the flow direction of the discharged airflow. The coupling slot 3463 may extend long in a direction parallel to the flow direction of the discharged airflow. Thus, the discharged airflow may also flow through the coupling slot 3463 and penetrate the second guide vane 34.

[0163] Refer to Figure 8 Describe the coupling structure of the guide vanes 32, 34 and the connecting rod 36.

[0164] The guide vanes 32, 34 may include coupling posts 3464 combined with the connecting rod 36. The coupling posts 3464 may be formed in the coupling slots 3263, 3463. The coupling posts 3464 may extend along the width direction of the guide vanes 32, 34. The movable parts 326, 346 may include the coupling posts 3464.

[0165] The guide vanes 32, 34 may include support ends 3465 extending from the coupling posts 3464. The support ends 3465 may support the guide vanes 32, 34. The support ends 3465 may support the movable parts 326, 346. The support ends 3465 may slide as the movable parts 326, 346 move. The support ends 3465 may be formed in a cylindrical shape. The radius of the support ends 3465 may be larger than the radius of the coupling posts 3464.

[0166] The connecting rod 36 may include a coupling groove 363 combined with the coupling post 3464. The connecting rod 362 may include the coupling groove 363. The coupling post 3464 may be inserted into the coupling groove 363. The coupling post 3464 may be rotationally combined with the coupling groove 363. Thus, the coupling post 3464 may move in a state of being combined with the coupling groove 363.

[0167] Refer to Figure 9Describe the thickness of the guide vanes 32 and 34.

[0168] The thickness of the guide vanes 32 and 34 can be changed along the flow direction of the discharge air flow. The thickness of the connecting portions 324 and 344 can be thinner than the thickness of the fixed portions 322 and 342. The thickness of the connecting portions 324 and 344 can be thinner than the thickness of the movable portions 326 and 346. Thereby, the flexibility of the connecting portions 324 and 344 can be improved.

[0169] The thickness of the fixed portions 322 and 342 can be thicker than the thickness of the connecting portions 324 and 344. Since the thickness of the fixed portions 322 and 342 is formed to be thicker than the thickness of the connecting portions 324 and 344, the fixing force to the coupling panel 31 can be improved.

[0170] The thickness of the movable portions 326 and 346 can be thicker than the thickness of the connecting portions 324 and 344. Since the thickness of the movable portions 326 and 346 is formed to be thicker than the thickness of the connecting portions 324 and 344, the rigidity of the movable portions 326 and 346 moved by the link 36 can be improved.

[0171] One surface 32b and 34b of the guide vanes 32 and 34 can be formed flat. One surface 32b of the first guide vane 32 can be formed flat. One surface 34b of the second guide vane 34 can be formed flat.

[0172] The other surfaces 32a and 34a of the guide vanes 32 and 34 can be recessed. In a region of the guide vanes 32 and 34 corresponding to the connecting portions 324 and 344, the other surfaces 32a and 34a can be recessed. Thereby, the thickness between one surface 32b and 34b and the other surfaces 32a and 34a of the guide vanes 32 and 34 can be thinned.

[0173] Refer to Figure 10 , and describe the chassis 60 combined with the guide module 30.

[0174] The chassis 60 can form a discharge flow path 180. The guide module 30 can be combined with the chassis 60. The guide module 30 can be combined with the rear guide portion 182 forming the discharge flow path 180.

[0175] The rear guiding part 182 may include a recessed part 632 combined with the guiding module 30. The recessed part 632 may be recessed from the surface of the rear guiding part 182. The surface of the rear guiding part 182 may refer to the side of the rear guiding part 182 that forms the discharge flow path 180. The combining panel 31 of the guiding module 30 may be combined with the recessed part 632. As the combining panel 31 is disposed in the recessed part 632, the surface of the combining panel 31 may be coplanarly disposed with the surface of the rear guiding part 182. The surface of the combining panel 31 may refer to the side where a plurality of guiding vanes 32, 34 are combined. The surface of the combining panel 31 and the surface of the rear guiding part 182 may be located on a continuous imaginary plane. The surface of the combining panel 31 and the surface of the rear guiding part 182 may form a continuous surface.

[0176] The rear guiding part 182 may include a driving groove 634. The guiding module 30 may receive a driving force through the driving groove 634. A driving part (not shown) for driving the guiding module 30 may be disposed on the back surface of the rear guiding part 182.

The driving shaft 365 may be connected to the driving part (not shown) through the driving groove 634 of the rear guiding part 182. The power of the driving part (not shown) may drive the driving shaft 365. As the driving shaft 365 moves, a plurality of guiding vanes 32, 34 connected to the connecting rod 36 may move integrally.

[0179] Refer to Figure 12 Describe the second vane 15 of the air conditioner 1.

[0180] The first discharge port 12a may open forward in the housing 10. The first discharge port 12a may be formed on the front surface of the housing 10. For example, the first discharge port 12a may be formed by extending long at the lower part of the front wall 102 of the housing 10.

[0181] The second discharge port 12b (not shown) may open downward in the housing 10. The second discharge port 12b (not shown) may be formed on the bottom surface of the housing 10. The second discharge port 12b (not shown) may be adjacent to the first discharge port 12a. For example, the second discharge port 12b (not shown) may be formed by extending long at the front part of the bottom surface of the housing 10.

[0182] The first discharge port 12a and the second discharge port 12b (not shown) may be adjacent to a corner of the housing 10. For example, the first discharge port 12a and the second discharge port 12b (not shown) may be adjacent to the lower corner of the front wall 102. The lower corner of the front wall 102 may correspond to the front corner of the bottom surface of the housing 10.

[0183] The first discharge port 12a may be open. The first discharge port 12a may not be closed. The second discharge port 12b (not shown) may be opened and closed. For example, the first discharge port 12a may always be open, and the second discharge port 12b (not shown) may be open when the air conditioner 1 is in the operating state and closed when the air conditioner 1 is in the stopped state. However, this is not limited thereto, and the second discharge port 12b (not shown) may also be closed when the air conditioner 1 is in the operating state.

[0186] The second blade 15 may open or close the second discharge port 12b (not shown). For example, when an operation signal is input to the air conditioner 1, the second blade 15 may open, and when an operation end signal is input to the air conditioner 1, the second blade 15 may close. However, this is not limited thereto, and the second blade 15 may also be closed when the air conditioner 1 is in the operating state.

[0187] The second blade 15 closing the second discharge port 12b (not shown) may be aligned coplanarly with the lower cover 106.

The guide panel 152 may be disposed inside the housing 10. The guide panel 152 may be disposed obliquely with respect to the second discharge port 12b (not shown). The guide panel 152 may open or close the second discharge port 12b (not shown).

[0190] The guide panel 152 can extend longitudinally. The guide panel 152 can include a longitudinally extending side. Concavities and convexities can be formed on the surface of the guide panel 152. The concavities and convexities can extend longitudinally along the length direction of the guide panel 152. The width of the guide panel 152 can be formed in a direction intersecting the length direction. The concavities and convexities can be repeated in the width direction of the guide panel 152. As the concavities and convexities are formed on the surface of the guide panel 152, the amount of condensed water formed on the surface of the guide panel 152 can be reduced.

[0191] The guide panel 152 can include a pair of long sides LS1, LS2 and a pair of short sides SS1, SS2. The concavities and convexities can extend longitudinally in a direction parallel to the pair of long sides LS1, LS2.

[0216] Refer to Figure 16 , and illustrate the coupling structure and function of the second blade 15.

[0217] The second blade 15 may be disposed at the second discharge port 12b (not shown). The second blade 15 may open or close the second discharge port 12b (not shown). The second blade 15 may be movable at the second discharge port 12b (not shown).

For example, the base panel 154 closing the second discharge port 12b (not shown) may be disposed coplanarly with the lower cover 106. The second blade 15 opening the second discharge port 12b (not shown) may be disposed inclined with respect to the bottom surface of the housing 10.

[0218] The discharge passage 180 may include a first discharge passage 1801 formed between the rear guide portion 182 and the front guide portion 184. The discharge passage 180 may include a second discharge passage 1802 formed between the first discharge passage 1801 and the discharge port 12. The second discharge passage 1802 may be formed between the second blade 15 and the front guide portion 184.

[0219] The rear guide portion 182 may extend curvedly from the air supply fan 17 toward the second blade 15. The downstream side edge of the rear guide portion 182 may be adjacent to the second blade 15. The downstream side end of the rear guide portion 182 may extend toward the first inclined portion 1523 of the second blade 15. The rear guide portion 182 may guide the air flow flowing in the first discharge passage 1801 toward the first inclined portion 1523 and the flat portion 1521. The discharge guide portion 122 may guide the air flow flowing in the second discharge passage 1802 toward the first discharge port 12a.

[0220] The air conditioner 1 may include a discharge guide portion 122 disposed between the first discharge port 12a and a second discharge port 12b (not shown). The discharge guide portion 122 may be disposed at the corner of the housing 10 where the first discharge port 12a and the second discharge port 12b (not shown) are formed. For example, the discharge guide portion 122 may be disposed on the inner side of the lower corner of the front wall 102.

[0221] The discharge guide portion 122 may be bent. The discharge guide portion 122 may be formed in a bent shape. The discharge guide portion 122 may include a first guide surface 1222 forming the first discharge port 12a.

The first guide surface 1222 may face the first blade 13. The first guide surface 1222 may be located on the lower side of the first blade 13. The first guide surface 1222 may guide the air flow flowing in the second discharge passage 1802 toward the first discharge port 12a.

[0223] Thus, the first guide surface may guide the air flow discharged through the first discharge port upward.

[0224] In addition, as the air flow is guided upward, indirect wind can be achieved.

[0225] The second guiding surface 1224 may be formed obliquely. The second guiding surface 1224 may be inclined downward in the forward direction. The second guiding surface 1224 may face the second blade 15. The second guiding surface 1224 may face the second inclined portion 1525. The second guiding surface 1224 may be located in front of the second blade 15. The second guiding surface 1224 may guide the airflow flowing in the second discharge passage 1802 toward the second discharge port 12b (not shown). The first guiding surface 1222 and the second guiding surface 1224 may be connected in a curved manner. The connecting portion where the first guiding surface 1222 and the second guiding surface 1224 are connected may be arc-shaped.

[0226] The closed second blade 15 may be adjacent to the discharge guiding portion 122. When the second blade 15 is closed, the gap between the second blade 15 and the discharge guiding portion 122 may become narrower. The second inclined portion 1525 of the second blade 15 may face the second guiding surface 1224. The second inclined portion 1525 may be adjacent to the second guiding surface 1224. The second inclined portion 1525 may be arranged parallel to the second guiding surface 1224. The rear guiding portion 182 may guide the airflow flowing in the first discharge passage 1801 toward the second blade 15. The second blade 15 may guide the airflow flowing in the second discharge passage 1802 toward the first guiding surface 1222. Thus, the closed second blade 15 may guide the airflow flowing in the discharge passage 180 toward the first discharge port 12a.

[0227] The closed second blade 15 guides the air after heat exchange. The air after heat exchange may flow along the guiding panel 152 of the second blade 15. The air after heat exchange flows on the surface of the guiding panel 152.

[0228] In the closed second blade 15, a temperature difference may occur between the surface of the guiding panel 152 where the air after heat exchange flows and the surface of the base panel 154 in contact with the external air.

[0229] Compared with other components of the housing, the second blade 15 has a relatively thin thickness. Therefore, due to the difference in the surface temperature of the guiding panel 152 and the surface temperature of the base panel 154, dew condensation may occur on the surface of the base panel 154.

[0230] However, as Figure 15 shown, the second blade 15 of the present invention can prevent dew condensation through the heat insulation member 156 arranged between the guiding panel 152 and the base panel 154.

[0231] The open second blade 15 can be separated from the discharge guide portion 122. When the second blade 15 is open, the distance between the second blade 15 and the discharge guide portion 122 can increase. The second inclined portion 1525 of the second blade 15 can be separated from the second guide surface 1224. The air flow flowing in the second discharge passage 1802 can be discharged through the separation gap between the second guide surface 1224 of the discharge guide portion 122 and the second blade 15 via the second discharge port 12b (not shown). Thus, the open second blade 15 can adjust the wind direction of the air flow discharged through the second discharge port 12b (not shown).
