Description

Technical Field

[0001] The present invention relates to an air conditioner, and more particularly, to an air conditioner having a guide module for adjusting the discharge air direction. Background Art

[0002] An air conditioner is a device that adjusts the indoor air temperature 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] The "linkage structure of an air conditioner" disclosed in Korean Patent Publication No. 10-1998-0049068 includes: a plurality of baffles coupled to the discharge port side; and a linkage that integrally rotates the plurality of baffles; the plurality of baffles are formed in a flat plate shape and have a constant overall thickness.

[0004] In the above-described conventional air conditioner, in order to adjust the air direction, a plurality of baffles are moved so as to approach the inner wall forming the discharge flow path. At this time, the baffles located at the edges among the plurality of baffles move in a direction approaching the inner wall, so that the flow path between the edge baffles and the inner wall becomes narrow and eddy currents are generated. Therefore, there is a problem that the discharged air flow does not flow smoothly.

[0005] In addition, in the above-described conventional air conditioner, the eddy currents generated at the edge side of the discharge flow path cannot be quickly discharged through the discharge port due to the plurality of baffles, so there is a problem of dew condensation on the baffles.

[0006] In addition, the above-described conventional air conditioner has a problem that bacteria such as mold multiply due to the condensed water formed on the baffles. This may be the cause of the odor of the discharged air flow.

[0087] 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 that forms an exhaust flow path 180.

[0088] 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.

[0089] 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.

[0090] 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.

[0093] The front guide part 184 may be disposed adjacent to the ejection port 12. The front guide part 184 may extend from the air supply fan 17 toward the ejection port 12. For example, the front guide part 184 may extend from the air supply fan 17 toward the first ejection port 12a. The front guide part 184 may extend in a curved manner. Thus, the ejected air flow can flow smoothly.

[0094] The air conditioner 1 may include an intermediate guide part 181 spaced apart from the front guide part 184. The intermediate guide part 181 may be disposed inside the housing 10. The air supply fan 17 may be disposed between the intermediate guide part 181 and the front guide part 184. The intermediate guide part 181 may guide the air flow that has passed through the air supply fan 17 toward the ejection flow path 180. For example, the intermediate guide part 181 is spaced apart rearward from the front guide part 184, and the air supply fan 17 may be located between the front guide part 184 and the intermediate guide part 181 and form an air flow. The intermediate guide part 181 may extend in a curved manner along the rotation direction of the air supply fan 17.

[0095] The air conditioner 1 may include a rear guide part 182 that forms the ejection flow path 180.

[0096] The rear guide part 182 may be connected to the intermediate guide part 181. The rear guide part 182 may extend from the intermediate guide part 181 toward the ejection port 12. For example, the rear guide part 182 may extend from the intermediate guide part 181 toward a second ejection port 12b (not shown) described later. The rear guide part 182 may be disposed below the intermediate guide part 181. The rear guide part 182 may be disposed below the air supply fan 17. The rear guide part 182 may be disposed adjacent to the ejection port 12.

[0097] 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.

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.

[0119] 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.

[0120] 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.

[0121] A pair of first guide vanes 32 may be respectively coupled to one end and the other end in the length 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. Accordingly, the flow direction of the airflow flowing in the discharge flow path 180 may be adjusted.

[0122] Refer to Figure 6 to describe a pair of first guide vanes 32.

[0123] 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 airflow.

[0124] 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 intersecting the flow direction of the discharged airflow. 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.

[0125] The first guide vane 32 may include a connecting portion 324 that connects the movable portion 326 and the 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.

[0126] 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.

[0127] The connecting portion 324 may be connected to the movable movable portion 326 and bent. For example, the connecting portion 324 may be bent as the movable portion 326 moves in the left - right direction.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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 long. The slit 3240 may start extending from the spaced - apart interval between the second connecting portion 3244 and the fixed portion 322. Forming the slit 3240 between the first connecting portion 3242 and the second connecting portion 3244 enables the first connecting portion 3242 that moves while adhering to the fixed portion 322 and the second connecting portion 3244 that moves freely to move independently without interference.

[0132] 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 link 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.

[0133] 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 the 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.

[0134] 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 the 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.

[0135] 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.

[0136] The movable part 326 may include a reinforcing part 3264 formed between a plurality of communication holes 3260. The reinforcing part 3264 may separate 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.

[0137] 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.

[0138] The coupling slot 3263 may be arranged in a line 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.

[0139] 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.

[0140] Refer to Figure 7 Describe the second guide vane 34.

[0141] 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.

[0142] 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.

[0143] The second guide vane 34 may include a connecting portion 344 that connects a movable portion 346 and a 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.

[0144] 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. Thus, the flexibility of the connecting portion 344 may be greater than the flexibility of the fixed portion 342 or the movable portion 346.

[0145] 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.

[0146] 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. Thus, the second connecting portion 3444 may move more freely as the movable portion 346 moves.

[0147] 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. Thus, the discharged air flow can smoothly pass through the second connecting portion 3444, and the generated noise can be reduced.

[0148] 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.

[0149] 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 extending 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.

[0150] 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.

[0151] 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.

[0152] Refer to Figure 8 Describe the coupling structure of the guide vanes 32, 34 and the connecting rod 36.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] Refer to Figure 9Describe the thickness of the guide vanes 32 and 34.

[0157] The thickness of the guide vanes 32 and 34 can be changed along the flow direction of the discharged 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.

[0158] 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.

[0159] 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 that are moved by the link 36 can be improved.

[0160] 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.

[0161] 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.

[0162] Refer to Figure 10 , and describe the chassis 60 combined with the guide module 30.

[0163] 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 that forms the discharge flow path 180.

[0164] The rear guide part 182 may include a recessed part 632 combined with the guide module 30. The recessed part 632 may be recessed from the surface of the rear guide part 182. The surface of the rear guide part 182 may refer to the side of the rear guide part 182 that forms the discharge flow path 180. The coupling panel 31 of the guide module 30 may be coupled to the recessed part 632. As the coupling panel 31 is disposed in the recessed part 632, the surface of the coupling panel 31 may be coplanarly disposed with the surface of the rear guide part 182. The surface of the coupling panel 31 may refer to the side to which a plurality of guide vanes 32, 34 are coupled. The surface of the coupling panel 31 and the surface of the rear guide part 182 may be located on a continuous imaginary plane. The surface of the coupling panel 31 and the surface of the rear guide part 182 may form a continuous surface.

[0165] The rear guide part 182 may include a driving groove 634. The guide module 30 may receive a driving force through the driving groove 634.

[0180] 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.
