[0001] The present invention relates to an air conditioner, and more particularly to an air conditioner provided with a blade (vane) to which a heat insulating member is coupled. An air conditioner (Air conditioner: air conditioner) is also called an air conditioner, an air conditioning device, an air conditioning (regulation) unit, a cooling and heating humidity control machine, etc.

[0002] 〔Related Art〕 This application is accompanied by a claim of priority under Article 4 of the Paris Convention based on Korean Patent Application No. 10-2023-0170001 (filing date: November 29, 2023 / DAS code: 27B0), and the invention of this application is based on the content disclosed in the Korean patent application. For reference, the specifications, claims, and drawings of the Korean patent application are incorporated into a part of this specification.

Background Art

[0003] 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 indoor unit that is installed vertically in a room is called a stand-type air conditioner, an indoor unit that is installed on an indoor wall is called a wall-mounted air conditioner, and an indoor unit that is installed on an indoor ceiling is called a ceiling-type air conditioner.

[0004] The "indoor unit of an air conditioner" disclosed in Korean Registered Patent No. 10-2149736 includes a main body having an inlet and an outlet, a heat exchanger that cools the indoor air inhaled through the inlet, a cross-flow fan that sucks the indoor air through the inlet and discharges the cooled air to the outlet, and a blade disposed at the outlet to control the wind direction of the discharged air flow, and both ends of the blade are formed sharply. A heat insulating material is provided between the inner surface and the outer surface of the blade.

[0005] In the conventional air conditioner, since heat insulating members are not arranged at both ends of the blade, there is a problem that condensation occurs due to the temperature difference between the inner surface and the outer surface at both ends of the blade.

[0006] Furthermore, the conventional air conditioner has the problem that it is difficult to position low-stretch insulation materials because the space formed inside both ends of the blade is not uniform. [Prior art documents] [Patent Documents]

[Claim 12] The system further includes a front guide extending from the blower fan in the direction of the first discharge port, The air conditioner according to claim 1, further comprising a discharge channel between the front guide and the vane through which an airflow directed toward the first discharge port flows.

[0022] In one aspect of the present disclosure for achieving the aforementioned objectives, the air conditioner includes a case having an intake port and a first discharge port located on the front and a second discharge port located on the lower surface; a blower fan disposed inside the case to form an airflow; an indoor heat exchanger for heat exchange between the air inside the case and a refrigerant; and vanes disposed at the second discharge port for opening and closing the second discharge port.

[0023] The vane includes a guide panel that forms one surface of the vane, a base panel that forms the other surface of the vane, and a heat insulating member disposed between the guide panel and the base panel.

[0024] The guide panel includes the flat portion and the inclined portion formed at an angle from the flat portion.

[0025] The vane includes a flat portion formed to be flat and an inclined portion that extends inclined from the flat portion.

[0026] The thermal insulation member includes a first thermal insulation member and a second thermal insulation member. The first thermal insulation member is positioned inside the flat portion. The second thermal insulation member is positioned inside the inclined portion.

[0027] The first and second insulating members are made of different materials. Therefore, the insulating members can be arranged from one end of the vane to the other.

[0028] The heat insulating member is placed in a accommodating space formed between the guide panel and the base panel, thereby reducing heat transfer between the guide panel and the base panel.

[0029] The first insulating member is placed between the flat portion and the base panel. The second insulating member is placed between the inclined portion and the base panel. Therefore, the first insulating member, which has high thermal insulation performance, can be placed between the flat portion, which is formed with a relatively uniform volume, and the base panel, while the second insulating member, which has high shrinkage performance, can be placed between the inclined portion, which is formed with an uneven volume, and the base panel.

[0030] The vane includes a supporter positioned in the housing space and separating the guide panel from the base panel, the supporter being located between the inclined portion and the flat portion, and the supporter being able to support the guide panel.

[0031] The supporter can divide the accommodation space into a first accommodation space where the first heat insulating member is located and a second accommodation space where the second heat insulating member is located.

[0032] The inclined portion includes a first inclined portion extending upstream from the flat portion in the direction of airflow and a second inclined portion extending downstream from the flat portion in the direction of airflow, and the second heat insulating member may be positioned at least one of the inside of the first inclined portion and the inside of the second inclined portion.

[0033] The further the inclined portion is from the flat portion, the smaller the accommodation space for the second heat insulating member can be.

[0034] The guide panel has irregularities formed on one surface that guides the airflow, which reduces the surface area of ​​the guide panel exposed to the discharged airflow.

[0035] The aforementioned irregularities may be formed on the flat portion and the inclined portion, respectively.

[0036] The base panel can be made lighter by forming irregularities on one surface facing the guide panel.

[0037] In one aspect of the present disclosure for achieving the aforementioned objectives, an air conditioner includes a case having an intake and an outlet, a blower fan disposed inside the case to form an airflow, an indoor heat exchanger for heat exchange between the air inside the case and a refrigerant, and a vane disposed at the outlet, the outlet including a first outlet opening to the front of the case and a second outlet opening to the bottom of the case, the vane being disposed at the second outlet to guide the airflow to the first outlet or to guide the airflow discharged through the second outlet, the vane including an insulating member disposed inside, the vane being able to close the second outlet and function as a discharge channel.

[0038] The vane includes a guide panel that guides airflow to the first discharge port or to the airflow discharged to the second discharge port, and a base panel that opens or closes the second discharge port. The heat insulating member is positioned between the guide panel and the base panel, and can reduce condensation that occurs on the vane due to the temperature difference between the inner and outer surfaces.

[0039] Since the guide panel includes a flat portion separated from the base panel and an inclined portion extending inclined from the flat portion, the airflow can flow smoothly, and the airflow control performance of the vane can be improved.

[0040] The thermal insulation member includes a first thermal insulation member disposed between the flat portion and the base panel, and a second thermal insulation member disposed between the inclined portion and the base panel. The first and second thermal insulation members are made of different materials, and the second thermal insulation member, which has high shrinkage properties, may be disposed between the inclined portion and the base panel where an uneven space is formed.

[0042] The second heat insulating member can be placed in at least one of the spaces formed between the first inclined portion and the base panel, and the space formed between the second inclined portion and the base panel, thereby improving the heat insulating performance at both ends of the vane.

[0043] The invention further includes a front guide extending from the blower fan toward the first discharge port, and a discharge channel is formed between the front guide and the vane through which airflow toward the first discharge port flows, and the vane can function as a discharge channel.

[0044] Specific details of other embodiments are included in the detailed description and drawings. [Effects of the Invention]

[0045] In at least one embodiment of the present disclosure, a first and second insulating member, made of different materials, are arranged inside the flat and inclined portions of the vane, respectively, thereby improving the thermal insulation performance of the vane.

[0062] The air conditioner 1 will be described with reference to Figure 1.

[0063] The air conditioner 1 may include a case 10 in which an intake port 11 and a discharge port 12 are formed. The case 10 may form the outer shape of the air conditioner 1. The case 10 may be elongated. The case 10 may have an internal space in which a refrigeration cycle device is housed.

[0064] Case 10 may include a front wall 102 that forms the front. The front wall 102 may face the interior space. The front wall 102 may face forward. Case 10 may include side walls 104 that form the sides. The side walls 104 may cover the sides of Case 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 that are bent from the front wall 102.

[0065] The intake port 11 can be formed in the case 10. The intake port 11 can be formed on one side of the case 10. For example, the intake port 11 can open on the top surface of the case 10. The intake port 11 can open upward in the case 10. This allows indoor air to flow into the interior of the case 10 through the intake port 11.

[0066] The discharge port 12 may be formed in the case 10. The discharge port 12 may be formed on the other side of the case 10. For example, the discharge port 12 may include a first discharge port 12a formed in the front wall 102 of the case 10. The discharge port 12 can be elongated. For example, a first discharge port 12a opening forward in the front wall 102 of the case 10 can be elongated in the left-right direction.

[0067] The air inside case 10 can be discharged into the room space through the discharge port 12. Similarly, air drawn in through the intake port 11 can be discharged through the discharge port 12. For example, the air inside case 10 can be discharged forward of the air conditioner 1 through the first discharge port 12a.

[0068] The air conditioner 1 may include a filter 20 positioned at the intake port 11. The filter 20 may be shaped to correspond to the shape of the intake port 11. The filter 20 can purify the air flowing into the intake port 11.

[0069] The air conditioner 1 may include vanes positioned at the discharge port 12. The vanes can guide the airflow discharged through the discharge port 12. The vanes may extend elongated in the longitudinal direction of the discharge port 12.

[0070] The vane may include a first vane 13 positioned at the first discharge port 12a. The first vane 13 may be fixed to the first discharge port 12a. The first discharge port 12a can maintain an open state at all times. The first vane 13 can guide the airflow discharged through the first discharge port 12a forward.

[0071] The air conditioner 1 may include a display 14 that displays operating information. The display 14 can show various types of information. For example, the display 14 can show information such as room temperature, set temperature, wind speed, wind direction, and indoor humidity. The display 14 may be located in the case 10. For example, the display 14 may be located on the front wall 102. The display 14 may be coupled to the rear side of the front wall 102. Light emitted through the display 14 can pass through the front wall 102. This allows the display 14 to show various types of information to the user.

[0072] Referring to Figure 2, the components arranged inside the air conditioner 1 will be described. The air conditioner 1 may include an indoor heat exchanger 16, a blower fan 17, and a guide structure that forms a discharge flow path 180.

[0073] The air conditioner 1 may include an indoor heat exchanger 16 located inside the case 10. The indoor heat exchanger 16 can exchange heat between the air inside the case 10 and the refrigerant. The indoor heat exchanger 16 can exchange heat between the air flowing in through the intake port 11 and the refrigerant. The air that has undergone heat exchange through the indoor heat exchanger 16 can be supplied to the indoor space through the discharge port 12. The indoor heat exchanger 16 can exchange heat between the airflow formed by the blower fan 17 and the refrigerant. The indoor heat exchanger 16 can function as an evaporator or a condenser. For example, the indoor heat exchanger 16 can function as an evaporator and supply cool air to the indoor space. For example, the indoor heat exchanger 16 can function as a condenser and supply warm air to the indoor space.

[0074] The air conditioner 1 may include a blower fan 17 located inside the case 10. The blower fan 17 can form an airflow that flows from the intake port 11 to the discharge port 12. The airflow formed by the blower fan 17 can exchange heat with the refrigerant in the indoor heat exchanger 16.

[0075] The blower fan 17 may be positioned adjacent to the indoor heat exchanger 16. For example, the blower fan 17 may be located downstream of the indoor heat exchanger 16 in the airflow direction. However, it is not limited to this, and the blower fan 17 may also be located upstream of the indoor heat exchanger 16 in the airflow direction.

[0076] In case 10, a discharge channel 180 may be formed through which the airflow formed by the blower fan 17 flows. The discharge channel 180 may be located downstream of the blower fan 17 in the direction of airflow. The discharge channel 180 may be located downstream of the indoor heat exchanger 16 in the direction of airflow. The airflow that has passed through the indoor heat exchanger 16 or the blower fan 17 can flow to the outlet 12 via the discharge channel 180. The discharge channel 180 may be connected to the outlet 12.

[0077] The air conditioner 1 may include a front guide 184 that forms a discharge channel 180. The front guide 184 may be located inside the case 10. The front guide 184 can separate the indoor heat exchanger 16 from the discharge channel 180. The front guide 184 can prevent air that has not passed through the indoor heat exchanger 16 from flowing into the discharge channel 180. The front guide 184 may be located below the indoor heat exchanger 16.

[0078] The front guide 184 may be positioned adjacent to the discharge port 12. The front guide 184 may extend from the blower fan 17 towards the discharge port 12. For example, the front guide 184 may extend from the blower fan 17 towards the first discharge port 12a. The front guide 184 may extend in a curved manner. This allows the discharge airflow to flow smoothly.

[0079] The air conditioner 1 may include a middle guide 181 spaced apart from the front guide 184. The middle guide 181 may be located inside the case 10. The blower fan 17 may be located between the middle guide 181 and the front guide 184. The middle guide 181 can guide the airflow that has passed through the blower fan 17 to the discharge channel 180. For example, the middle guide 181 may be spaced behind the front guide 184, and the blower fan 17 may be located between the front guide 184 and the middle guide 181 to form an airflow. The middle guide 181 may extend in a curved direction in the rotational direction of the blower fan 17.

[0080] The air conditioner 1 may include a rear guide 182 that forms a discharge passage 180. The discharge passage 180 may be formed between a front guide 184 and a rear guide 182. The rear guide 182 may be spaced away from the front guide 184. For example, the rear guide 182 may be spaced rearward from the front guide 184.

[0081] The rear guide 182 may be connected to the middle guide 181. The rear guide 182 may extend from the middle guide 181 in the direction of the discharge port 12. For example, the rear guide 182 may extend from the middle guide 181 in the direction of the second discharge port 12b (not shown), which will be described later. The rear guide 182 may be located below the middle guide 181. The rear guide 182 may be located below the blower fan 17. The rear guide 182 may be located adjacent to the discharge port 12.

[0082] The discharge port 12 may include a second discharge port 12b (not shown) that opens downward in the case 10. The second discharge port 12b (not shown) may be formed in the lower side wall 106 of the case 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 in the front wall 102 of the case 10, and the second discharge port 12b (not shown) may open downward in the lower side wall 106 of the case 10. As a result, the discharged air may be discharged forward and downward through the first discharge port 12a and the second discharge port 12b (not shown), respectively.

[0083] The vane may include a second vane 15 positioned at the second discharge port 12b (not shown). The second vane 15 can open or close the second discharge port 12b (not shown).

[0084] The air conditioner 1 may include a guide module 30 positioned in the discharge channel 180. The guide module 30 may include a plurality of guide vanes (see Figure 5, 32, 34). The guide module 30 can guide the direction of airflow through the discharge channel 180. For example, the guide module 30 can guide the direction of airflow through the discharge channel 180 in the left-right direction. This allows for more precise control of the direction of airflow discharged into the room.

[0085] The guide module 30 can be coupled to the rear guide 182. The guide module 30 can be positioned between the rear guide 182 and the front guide 184. Multiple guide vanes (see Figure 5, 32, 34) are movable in the left-right direction. The guide module 30 can be positioned downstream of the blower fan 17 in the airflow direction. The guide module 30 can be positioned on the airflow path between the outlet 12 and the blower fan 17.

[0086] Referring to Figure 3, the internal layout structure of the air conditioner 1 will be explained.

[0087] The air conditioner 1 may include a radar module 40 that senses occupants in the indoor space. The radar module 40 can sense biological signals in the indoor space. For example, the radar module 40 can sense the location of occupants, the number of occupants, their activity level, their movement, their respiratory rate, their body temperature, their biological state, their posture, etc. The air conditioner 1 can control at least one of the following based on the sensed biological signal result: wind speed, wind direction, or set temperature.

[0088] The radar module 40 may include a radar sensor 44 for sensing biological signals. The radar sensor 44 can transmit and / or receive radio waves. The radar sensor 44 may be positioned in the direction of the indoor space. The radar sensor 44 can sense biological signals in the indoor space. The radar sensor 44 may include a thermopile sensor. The radar sensor 44 can use radio waves that penetrate and / or reflect obstacles. The radar sensor 44 can sense biological signals by transmitting and receiving radio waves of a specific frequency. For example, the radar sensor 44 can sense biological signals in the indoor space using millimeter waves (mm-Wave).

[0089] The radar sensor 44 may be located inside the case 10. The radar sensor 44 may be located adjacent to the electrical unit 50. The internal space of the case 10 is divided into a first internal space where the indoor heat exchanger 16 and the blower fan 17 are located, and a second internal space where the electrical unit 50 is located. The radar sensor 44 may be located in the second internal space. The radar sensor 44 may be located between the indoor heat exchanger 16 and the electrical unit 50.

[0090] The radar sensor 44 may be positioned on the front of the case 10. The radar sensor 44 may be positioned on the front wall 102 of the case 10. The radar sensor 44 may be positioned on the rear of the front wall 102. The radar sensor 44 can use radio waves that penetrate the front wall 102. For example, the radar sensor 44 can sense biological signals in the room by transmitting and / or receiving radio waves that penetrate the front wall 102.

[0091] The radar sensor 44 may be positioned in the direction of the interior space. The radar sensor 44 may be positioned in the direction of the front. The radar sensor 44 may be positioned facing the front wall 102.

[0092] The air conditioner 1 may include an electrical unit 50. The electrical unit 50 may be located in a second internal space of the case 10. The electrical unit 50 may be located away from the indoor heat exchanger 16 and / or the blower fan 17.

[0093] The display 14 may be positioned in front of the electrical unit 50. The display 14 may be positioned behind the front wall 102. The display 14 may be positioned between the electrical unit 50 and the front wall 102.

[0094] The air conditioner 1 may include a drain fan 19 for collecting condensate generated in the indoor heat exchanger 16. The drain fan 19 may be located inside the case 10. The drain fan 19 may be located below the indoor heat exchanger 16. This allows the condensate generated in the indoor heat exchanger 16 to fall into the drain fan 19. The drain fan 19 may extend along the longitudinal direction of the indoor heat exchanger 16.

[0095] Referring to Figure 4, the arrangement structure of the components placed inside the air conditioner 1 will be explained.

[0096] The air conditioner 1 may include a chassis 60 located inside the case 10. The chassis 60 may be coupled to the case 10. The indoor heat exchanger 16 may be coupled to the chassis 60. The blower fan 17 may be coupled to the chassis 60.

[0097] The chassis 60 may include a fan holder 61 coupled to the blower fan 17. The fan holder 61 may include a first fan holder 61a and a second fan holder 61b spaced apart in the longitudinal direction of the blower fan 17. The case 10 can be divided into a first internal space and a second internal space based on the second fan holder 61b. That is, based on the second fan holder 61b, a first internal space can be formed on one side where the blower fan 17 and the indoor heat exchanger 16 are located, and a second internal space can be formed on the other side where the electrical components 50 are located.

[0098] The rear guide 182 may be located in the first internal space. The rear guide 182 may be coupled to the chassis 60.

[0099] The guide module 30 may be located in the first internal space. The guide module 30 may be coupled to the rear guide 182.

[0100] The guide module 30 will be described with reference to Figure 5.

[0101] The guide module 30 may include a plurality of guide vanes 32, 34 arranged in the discharge channel 180. The plurality of guide vanes 32, 34 may be arranged in a line. 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 intersecting the flow direction of the airflow directed toward the discharge port 12. For example, if the airflow flows in the vertical direction, the plurality of guide vanes 32, 34 may be arranged in the horizontal direction.

[0102] 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 positioned at the ends of the guide module 30. The pair of first guide vanes 32 may be positioned close to the inner wall forming the discharge channel 180. The pair of first guide vanes 32 may be positioned at one end and the other end of the guide module 30 in the longitudinal direction, respectively. The pair of first guide vanes 32 may be positioned on one side and the other side in the direction in which the plurality of guide vanes 32, 34 are arranged, respectively. The first guide vanes 32 may form the edges of the plurality of guide vanes 32, 34.

[0103] The multiple guide vanes 32, 34 may include a multiple second guide vanes 34 positioned between a pair of first guide vanes 32. The multiple second guide vanes 34 may be arranged in a direction in which the pair of first guide vanes 32 are spaced apart. That is, the direction in which the multiple second guide vanes 34 are arranged and the direction in which the pair of first guide vanes 32 are spaced apart can be parallel.

[0104] The guide module 30 may include a coupling panel 31 to which multiple guide vanes 32, 34 are coupled. The coupling panel 31 can extend for a long distance. The coupling panel 31 may be coupled to the discharge channel 180. A pair of first guide vanes 32 may be coupled to one end and the other end of the coupling panel 31, respectively. Multiple second guide vanes 34 may be coupled to the coupling panel 31 between a pair of first guide vanes 32.

[0105] The guide module 30 may include a link 36 connected to a plurality of guide vanes 32, 34. The link 36 can be long. The link 36 may include a link panel 364 and a link stick 362 extending 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.

[0106] A pair of first guide vanes 32 can be coupled to one and the other longitudinal end of the link stick 362, respectively. Multiple second guide vanes 34 can be coupled to the link stick 362 and the link panel 364. Multiple guide vanes 32, 34 can move integrally with the link 36. For example, while the link 36 moves in the left-right direction, multiple guide vanes 32, 34 can move in the left-right direction. This allows the flow direction of the airflow through the discharge channel 180 to be adjusted.

[0107] The pair of first guide vanes 32 will be described with reference to Figure 6.

[0108] The first guide vane 32 may include a fixed portion 322 that is coupled to the coupling panel 31. The fixed portion 322 can be fixed to the coupling panel 31. The width of the fixed portion 322 can increase toward the direction of the discharge airflow.

[0109] The first guide vane 32 may include a movable part 326 to which a link 36 is connected. The movable part 326 may be separated from the fixed part 322. The movable part 326 may move. The movable part 326 may move in a direction intersecting the flow direction of the discharge airflow. For example, the movable part 326 may move left and right by the connected link 36. The width of the movable part 326 may be greater than the width of the fixed part 322.

[0110] 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 increase as it moves from the fixed portion 322 towards the movable portion 326.

[0111] The thickness of the connecting portion 324 is made thinner than the thickness of the fixed portion 322. The thickness of the connecting portion 324 is made thinner than the thickness of the movable portion 326. As a result, the flexibility of the connecting portion 324 can be greater than the flexibility of the fixed portion 322 or the movable portion 326.

[0112] The connecting portion 324 is connected to a movable portion 326 and bent. For example, the connecting portion 324 is bent by the movable portion 326, which moves in the left-right direction.

[0113] 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 located between the movable portion 326 and the fixed portion 322. The second connecting portion 3244 extends from the movable portion 326. The second connecting portion 3244 extends from the movable portion 326 toward the fixed portion 322 and may be separated from the fixed portion 322. That is, the second connecting portion 3244 may not be connected to the fixed portion 322. This allows the second connecting portion 3244 to move integrally with the movement of the movable portion 326.

[0114] The second connecting portion 3244 may include a curved portion 3245 whose edge facing the fixed portion 322 is curved. That is, the edge of the second connecting portion 3244 facing the fixed portion 322 can be formed in a curved shape. This allows the discharged airflow to pass smoothly through the second connecting portion 3244, thereby reducing noise.

[0115] The width of the connecting portion 324 can increase as you move from the fixed portion 322 towards the movable portion 326. The width of the second connecting portion 3244 can also increase as you move from the fixed portion 322 towards the movable portion 326.

[0116] The first connecting portion 3242 and the second connecting portion 3244 can 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 be elongated. The slit 3240 may extend from the separation distance between the second connecting portion 3244 and the fixed portion 322. With the slit 3240 formed between the first connecting portion 3242 and the second connecting portion 3244, the first connecting portion 3242 which moves subordinate to the fixed portion 322 and the second connecting portion 3244 which moves freely can move independently without interfering with each other.

[0117] The movable part 326 may include a first movable part 3261 directly connected to the connecting part and a second movable part 3262 connected to the link 36. The first movable part 3261 can connect the second movable part 3262 and the connecting part 324. The first connecting part 3242 and the second connecting part 3244 can be connected to the first movable part 3261. The first connecting part 3242 can connect the first movable part 3261 and the fixed part 322. The thickness of the first movable part 3261 can increase from the first connecting part 3242 to the second movable part 3262. Due to the change in thickness of the first movable part 3261, a step may not be formed between the connecting part 324 and the movable part 326. This allows the airflow along the guide vanes 32 and 34 to flow smoothly.

[0118] 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 guide vanes 32, 34. The communication hole 3260 may be formed in a direction intersecting the flow direction of the discharge airflow. The communication hole 3260 may be formed in a direction in which the multiple guide vanes 32, 34 are arranged. This allows the airflow flowing along the first guide vane 32 to flow through the first guide vane 32.

[0119] The communication holes 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 discharge 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.

[0120] The communication hole 3260 can extend for a long distance. The communication hole 3260 can extend for a long distance in a direction parallel to the flow direction of the discharge airflow. The communication hole 3260 can extend for a long distance in a direction intersecting the width direction of the movable part 326. For example, the communication hole 3260 can extend for a long distance in the vertical direction or the front-back direction. This allows the airflow flowing through the discharge channel to smoothly pass through the communication hole 3260.

[0121] The movable part 326 may include a brace 3264 formed between a plurality of communication holes 3260. The brace 3264 can partition the plurality of communication holes 3260. The brace 3264 can extend over a long distance. The brace 3264 can extend in a direction parallel to the flow direction of the discharged airflow. For example, the brace 3264 can extend over a long distance in the vertical or horizontal direction. The brace 3264 may include a plurality of braces 3264 formed between a plurality of communication holes 3260. The rigidity of the movable part 326 can be improved by forming a brace 3264 between the communication holes 3260 that extends in the flow direction of the discharged airflow.

[0122] The guide vanes 32 and 34 may include coupling slots 3263 in which links 36 are positioned. The coupling slots 3263 may be formed in the movable part 326. The coupling slots 3263 may be through holes formed in the guide vanes 32 and 34. The coupling slots 3263 may be formed in a direction intersecting the flow direction of the discharge airflow. The coupling slots 3263 may extend for a long distance in a direction parallel to the flow direction of the discharge airflow. This allows the discharge airflow to flow through the guide vanes 32 and 34 even through the coupling slots 3263.

[0123] The coupling slot 3263 may be arranged in a row with a plurality of communication holes 3260. For example, the coupling slot 3263 and the plurality of communication holes 3260 may be formed in a row in the vertical or front-back direction on the movable part 326.

[0124] The coupling panel 31 may include a hook 312 that is coupled to the discharge channel 180. For example, the coupling panel 31 may be hook-coupled to a rear guide 182 that forms the discharge channel 180.

[0125] The second guide vane 34 will be described with reference to Figure 7.

[0126] The second guide vane 34 may include a fixed portion 342 that is coupled to the coupling panel 31. The fixed portion 342 can be fixed to the coupling panel 31. The width of the fixed portion 342 can increase toward the direction of the discharge airflow.

[0127] The second guide vane 34 may include a movable part 346 to which a link 36 is connected. The movable part 346 may be separated from the fixed part 342. The movable part 346 is movable. The movable part 346 can move in a direction intersecting the flow direction of the discharge airflow. For example, the movable part 346 can move in the left-right direction by the connected link 36. The width of the movable part 346 is greater than the width of the fixed part 342.

[0128] The second guide vane 34 may include a connecting portion 344 that links 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 increase as it moves from the fixed portion 342 towards the movable portion 346.

[0129] The thickness of the connecting portion 344 can be thinner than the thickness of the fixed portion 342. The thickness of the connecting portion 344 can be thinner than the thickness of the movable portion 346. As a result, the flexibility of the connecting portion 344 can be greater than the flexibility of the fixed portion 342 or the movable portion 346.

[0130] The connecting portion 344 is connected to the movable portion 346 and bent. For example, the connecting portion 344 is bent in accordance with the movement of the movable portion 346 in the left-right direction.

[0131] 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 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 separated from the fixed portion 342. That is, the second connecting portion 3444 may not be connected to the fixed portion 342. This allows the second connecting portion 3444 to move more freely in accordance with the movement of the movable portion 346.

[0132] The second connecting portion 3444 may include a curved portion 3245 whose edge facing the fixed portion 342 is curved. That is, the edge of the second connecting portion 3444 facing the fixed portion 342 may be formed in a curved shape. This allows the discharged airflow to pass smoothly through the second connecting portion 3444, and the noise generated may be reduced.

[0133] The width of the connecting portion 344 can increase from the fixed portion 342 to the movable portion 346. The width of the second connecting portion 3444 can increase from the fixed portion 342 to the movable portion 346.

[0134] The first connecting portion 3442 and the second connecting portion 3444 can 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 can be long. The slit 3440 can extend from the separation distance between the second connecting portion 3444 and the fixed portion 342. With the slit 3440 formed between the first connecting portion 3442 and the second connecting portion 3444, the first connecting portion 3442 which moves subordinate to the fixed portion 342 and the second connecting portion 3444 which moves freely can move independently without interfering with each other.

[0135] The movable part 346 may include a first movable part 3461 directly connected to the connecting part, and a second movable part 3462 to which the link 36 is connected. The first movable part 3461 can connect the second movable part 3462 and the connecting part 344. The first connecting part 3442 and the second connecting part 3444 can be connected to the first movable part 3461. The first connecting part 3442 can connect the first movable part 3461 and the fixed part 342. The thickness of the first movable part 3461 may increase from the first connecting part 3442 to the second movable part 3462. The change in thickness of the first movable part 3461 may prevent the formation of a step between the connecting part 344 and the movable part 346. This allows the airflow along the guide vanes 32 and 34 to flow smoothly.

[0136] The second guide vane 34 may include a coupling slot 3463 in which a link 36 is positioned. The coupling slot 3463 may be formed in the movable part 346. The coupling slot 3463 may be a through-hole formed in the guide vanes 32, 34. The coupling slot 3463 may be formed in a direction intersecting the flow direction of the discharge airflow. The coupling slot 3463 may extend for a long distance in a direction parallel to the flow direction of the discharge airflow. This allows the discharge airflow to flow through the guide vanes 32, 34 even through the coupling slot 3463.

[0137] The coupling slot 3463 may be arranged in a row with a plurality of communication holes 3260. For example, the coupling slot 3463 and the plurality of communication holes 3260 may be formed in a row in the vertical or front-to-back direction on the movable part 346.

[0138] Referring to Figure 8, the coupling structure of the guide vanes 32 and 34 and link 36 will be described.

[0139] Guide vanes 32, 34 may include connecting columns 3464 to which links 36 are connected. Connecting columns 3464 may be formed in connecting slots 3263, 3463. Connecting columns 3464 may extend in the width direction of guide vanes 32, 34. Movable parts 326, 346 may include connecting columns 3464.

[0140] The guide vanes 32 and 34 may include support ends 3465 extending from the connecting column 3464. The support ends 3465 can support the guide vanes 32 and 34. The support ends 3465 can support the movable parts 326 and 346. The support ends 3465 can slide while the movable parts 326 and 346 are moving. The support ends 3465 may be formed in a cylindrical shape. The radius of the support ends 3465 may be greater than the radius of the connecting column 3464.

[0141] Link 36 may include a coupling groove 363 that connects to a coupling column 3464. Link stick 362 may also include a coupling groove 363. The coupling column 3464 may be inserted into the coupling groove 363. The coupling column 3464 may be rotatably coupled to the coupling groove 363. This allows the coupling column 3464 to move while coupled to the coupling groove 363.

[0142] Referring to Figure 9, the thicknesses of the guide vanes 32 and 34 will be explained.

[0143] The thickness of the guide vanes 32 and 34 may vary as they move in the direction of the discharged airflow. The thickness of the connecting parts 324 and 344 can be thinner than that of the fixed parts 322 and 342. The thickness of the connecting parts 324 and 344 can be thinner than that of the movable parts 326 and 346. This can improve the flexibility of the connecting parts 324 and 344.

[0144] The thickness of the fixing parts 322 and 342 may be greater than the thickness of the connecting parts 324 and 344. By forming the fixing parts 322 and 342 to be thicker than the connecting parts 324 and 344, the fixing force that secures them to the connecting panel 31 can be improved.

[0145] The thickness of the movable parts 326 and 346 may be greater than the thickness of the connecting parts 324 and 344. By forming the movable parts 326 and 346 to be thicker than the thickness of the connecting parts 324 and 344, the rigidity of the movable parts 326 and 346 that are moved by the link 36 may be improved.

[0146] One surface 32b, 34b of the guide vanes 32, 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.

[0147] 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. This allows the thickness between one surface 32b and 34b of the guide vanes 32 and 34 and the other surface 32a and 34a to be reduced.

[0148] Referring to Figure 10, the chassis 60 to which the guide module 30 is attached will be described.

[0149] The chassis 60 can form a discharge channel 180. The guide module 30 can be coupled to the chassis 60. The guide module 30 can be coupled to a rear guide 182 that forms the discharge channel 180.

[0150] The rear guide 182 may include a recess 632 to which the guide module 30 is coupled. The recess 632 may be recessed from the surface of the rear guide 182. The surface of the rear guide 182 may refer to one surface of the rear guide 182 that forms the discharge channel 180. The coupling panel 31 of the guide module 30 may be coupled to the recess 632. While the coupling panel 31 is positioned in the recess 632, the surface of the coupling panel 31 may be positioned parallel to the surface of the rear guide 182. The surface of the coupling panel 31 may refer to one surface 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 182 may be located on a continuous virtual plane. The surface of the coupling panel 31 and the surface of the rear guide 182 may form a continuous plane.

[0151] The rear guide 182 may include a drive groove 634. The guide module 30 can receive driving force through the drive groove 634. A drive unit (not shown) that drives the guide module 30 may be located on the back surface of the rear guide 182. The drive unit (not shown) can drive the link 36 of the guide module 30 via the drive groove 634.

[0152] The guide module 30 will be described with reference to Figure 11.

[0153] The guide module 30 may include a drive shaft 365 that receives the driving force. The drive shaft 365 may be formed on the link 36. The drive shaft 365 may be formed on the link panel 364 of the link 36. The drive shaft 365 may be connected to a drive unit (not shown) via a drive groove 634 of the rear guide 182. Power from the drive unit (not shown) can drive the drive shaft 365. As the drive shaft 365 moves, the multiple guide vanes 32, 34 connected to the link 36 can move together as a unit.

[0154] Referring to Figure 12, the second vane 15 of the air conditioner 1 will be described.

[0155] The first discharge port 12a may open forward into the case 10. The first discharge port 12a may be formed on the front surface of the case 10. For example, the first discharge port 12a may be formed extending long from the lower part of the front wall 102 of the case 10.

[0156] A second discharge port 12b (not shown) may open downward into the case 10. The second discharge port 12b (not shown) may be formed on the lower surface of the case 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 extending for a long distance into the front part of the lower surface of the case 10.

[0157] The first discharge port 12a and the second discharge port 12b (not shown) can be adjacent to one edge of the case 10. For example, the first discharge port 12a and the second discharge port 12b (not shown) can be adjacent to the lower edge of the front wall 102. The lower edge of the front wall 102 can correspond to the front edge of the lower surface of the case 10.

[0158] The first discharge port 12a may be opened. 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 operation and closed when it is stopped. However, it is not limited to this, and the second discharge port 12b (not shown) may also be closed when the air conditioner 1 is in operation.

[0159] The air conditioner 1 may include a lower cover 106 coupled to the bottom of the case 10. The lower cover 106 may be detachably coupled to the case 10. The lower cover 106 may form the bottom surface of the case 10.

[0160] The second vane 15 may be positioned at the second discharge port 12b (not shown). The second vane 15 may be coupled to the case 10. The second vane 15 may be coupled to the lower cover 106.

[0161] The second vane 15 can open or close the second discharge port 12b (not shown). For example, the second vane 15 may open when an operation signal is input to the air conditioner 1, and may close when an operation termination signal is input to the air conditioner 1. However, it is not limited to this, and the second vane 15 may also be closed when the air conditioner 1 is in operation.

[0162] The second vane 15 that closes the second discharge port 12b (not shown) may be aligned parallel to the lower cover 106. For example, the lower surface of the second vane 15 that closes the second discharge port 12b (not shown) may be aligned parallel to the lower surface of the lower cover 106.

[0163] The structure of the second vane 15 will be described with reference to Figures 13 and 14.

[0164] The second vane 15 may include a guide panel 152. The guide panel 152 may form one surface of the second vane 15. The guide panel 152 can guide the discharge airflow. The guide panel 152 may be positioned inside the case 10. The guide panel 152 may be positioned at an angle to the second discharge port 12b (not shown). The guide panel 152 may open or close the second discharge port 12b (not shown).

[0165] The guide panel 152 may be elongated. The guide panel 152 may include an elongated surface. The guide panel 152 may have irregularities formed on its surface. The irregularities may extend elongated in the longitudinal direction of the guide panel 152. The guide panel 152 may have width formed in a direction where the longitudinal directions intersect. The irregularities may be repeated in the width direction of the guide panel 152. By forming irregularities 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.

[0166] The guide panel 152 may include a pair of long sides LS1, LS2 and a pair of short sides SS1, SS2. The irregularities may extend in a direction parallel to the pair of long sides LS1, LS2. The irregularities may be arranged in the longitudinal direction of the pair of short sides SS1, SS2. One region of the guide panel 152 on which the irregularities are formed may be separated from the pair of long sides LS1, LS2. One region of the guide panel 152 on which the irregularities are formed may be separated from the pair of short sides SS1, SS2.

[0167] The second vane 15 may include coupling flanges 1522 that are coupled to the case 10. The coupling flanges 1522 may be formed on the guide panel 152. The coupling flanges 1522 may protrude from the guide panel 152. The coupling flanges 1522 may be formed on the longitudinal ends of the second vane 15, respectively. For example, a pair of coupling flanges 1522 may be formed on the left and right ends of the second vane 15, respectively.

For example, the insulating member 156 may be bonded to at least one of the guide panel 152 and the base panel 154.

[0173] The thermal insulation member 156 and the guide panel 152 may be made of different materials. The thermal insulation member 156 and the base panel 154 may be made of different materials. For example, the thermal insulation member 156 may be made of polyethylene (PE) material.

[0174] The second vane 15 may include a supporter 1528 positioned between the guide panel 152 and the base panel 154. The supporter 1528 may be positioned in the accommodation space. The supporter 1528 may extend elongated in the longitudinal direction of the second vane 15. The supporter 1528 may protrude from the guide panel 152. For example, the supporter 1528 may protrude from the back surface of the guide panel 152 toward the base panel 154. The supporter 1528 can support the guide panel 152. The supporter 1528 can separate the guide panel 152 and the base panel 154.

[0175] The supporter 1528 can partition the containment space 150 into a first containment space 1501 and a second containment space 1502. The first containment space 1501 can be located in front of the supporter 1528. The second containment space 1502 can be located behind the supporter 1528. The volume of the second containment space 1502 may be larger than the volume of the first containment space 1501.

[0176] The thermal insulation member 156 may include a first thermal insulation member 1561 placed in the first accommodation space 1501 and a second thermal insulation member 1562 placed in the second accommodation space. The first thermal insulation member 1561 and the second thermal insulation member 1562 may be made of different materials. The elasticity of the second thermal insulation member 1562 may be higher than that of the first thermal insulation member 1561. For example, the first thermal insulation member 1561 may be made of polyethylene (PE) material and the second thermal insulation member 1562 may be made of polyurethane (PU) material.

[0179] This allows for a reduction in the weight of the base panel.

[0180] Furthermore, while reducing the weight of the base panel, the drive torque of the motor used to drive the second vane can be lowered.

[0181] Furthermore, the motor's driving torque can be reduced while simultaneously decreasing the motor's driving noise.

[0182] The height of the guide panel 152 can be reduced as it approaches the longer sides LS1 and LS2. For example, the height of the guide panel 152 can be reduced as it approaches the first longer side LS1 and the second longer side LS2.

[0183] The guide panel 152 can be made lower in height towards the rear end. The guide panel 152 may include a first inclined portion 1523 that slopes downward in the rearward direction. The first inclined portion 1523 may be connected to a flat portion 1521 of the guide panel 152. A first heat insulating member 1561 may be placed between the first inclined portion 1523 and the base panel 154.

[0184] The guide panel 152 can be made lower in height towards the front. The guide panel 152 may include a second inclined section 1525 that slopes downward in the forward direction. The second inclined section 1525 may be connected to a flat section 1521 of the guide panel 152. A second accommodation space 1502 may be formed between the second inclined section 1525 and the base panel 154.

[0186] The irregularities of the guide panel 152 may be formed on the flat portion 1521. The irregularities of the guide panel 152 may be formed on the first inclined portion 1523 and / or the second inclined portion 1525. For example, the irregularities of the guide panel 152 may be formed from the upper surface of the first inclined portion 1523, through the upper surface of the flat portion 1521, to the upper surface of the second inclined portion 1525.

[0187] The heat insulating member 156 may be placed on at least one of the first inclined portion 1523 and the second inclined portion 1525.

[0188] The second heat insulating member 1562 may be positioned inside the second inclined portion 1525. The second heat insulating member 1562 may be positioned in the second accommodation space 1502 formed between the second inclined portion 1525 and the base panel 154.

[0191] Referring to Figure 16, the bonding structure and function of the second vane 15 will be described.

[0192] The second vane 15 may be positioned at the second discharge port 12b (not shown). The second vane 15 can close the second discharge port 12b (not shown). The second vane 15 can be operated at the second discharge port 12b (not shown). The second vane 15 that closes the second discharge port 12b (not shown) may be positioned parallel to the bottom surface of the case 10. For example, the base panel 154 that closes the second discharge port 12b (not shown) may be positioned parallel to the lower cover 106. The second vane 15 that opens the second discharge port 12b (not shown) may be positioned diagonally to the bottom surface of the case 10.

[0193] The discharge channel 180 may include a first discharge channel 1801 formed between the rear guide 182 and the front guide 184. The discharge channel 180 may also include a second discharge channel 1802 formed between the first discharge channel 1801 and the discharge port 12. The second discharge channel 1802 may be formed between the second vane 15 and the front guide 184.

[0194] The rear guide 182 can bend and extend from the blower fan 17 toward the second vane 15. The downstream end of the rear guide 182 can be adjacent to the second vane 15. The downstream end of the rear guide 182 can extend toward the first inclined portion 1523 of the second vane 15. The rear guide 182 can guide the airflow through the first discharge channel 1801 toward the first inclined portion 1523 and the flat portion 1521. The second discharge guide 122 can guide the airflow through the second discharge channel 1802 toward the first discharge port 12a.

[0195] The air conditioner 1 may include a discharge guide 122 positioned between a first discharge port 12a and a second discharge port 12b (not shown). The discharge guide 122 may be positioned on the edge of the case 10 in which the first discharge port 12a and the second discharge port 12b (not shown) are formed. For example, the discharge guide 122 may be positioned on the inner surface of the lower end edge of the front wall 102.

[0196] The discharge guide 122 is bendable. The discharge guide 122 may be formed by bending. The discharge guide 122 may include a first guide surface 1222 that forms a first discharge port 12a. The discharge guide 122 may include a second guide surface 1224 that forms a second discharge port 12b (not shown).

[0197] The first guide surface 1222 may be formed at an angle. The first guide surface 1222 may be inclined upward in the forward direction. The first guide surface 1222 may face the first vane 13. The first guide surface 1222 may be located below the first vane 13. The first guide surface 1222 may guide the airflow flowing through the second discharge channel 1802 to the first discharge port 12a.

[0198] This allows the first guide surface to guide the airflow discharged through the first discharge port upward.

[0199] Furthermore, it is possible to create indirect airflow while guiding the airflow upwards.

[0200] The second guide surface 1224 may be formed at an angle. The second guide surface 1224 may be inclined downward in the forward direction. The second guide surface 1224 may face the second vane 15. The second guide surface 1224 may face the second inclined portion 1525. The second guide surface 1224 may be positioned in front of the second vane 15. The second guide surface 1224 can guide the airflow flowing through the second discharge channel 1802 to the second discharge port 12b (not shown). The first guide surface 1222 and the second guide surface 1224 may be connected by bending. The connection between the first guide surface 1222 and the second guide surface 1224 may be rounded.

[0201] A closed second vane 15 can be adjacent to the discharge guide 122. When the second vane 15 is closed, the distance between it and the discharge guide 122 can be reduced. The second inclined portion 1525 of the second vane 15 can face the second guide surface 1224. The second inclined portion 1525 can be adjacent to the second guide surface 1224. The second inclined portion 1525 can be positioned parallel to the second guide surface 1224. The rear guide 182 can guide the airflow flowing through the first discharge channel 1801 to the second vane 15. The second vane 15 can guide the airflow flowing through the second discharge channel 1802 to the first guide surface 1222. As a result, a closed second vane 15 can guide the airflow flowing through the discharge channel 180 to the first discharge port 12a.

[0202] The closed second vane 15 guides the heat-exchanged air. The heat-exchanged air can flow along the guide panel 152 of the second vane 15. The heat-exchanged air flows along the surface of the guide panel 152.

[0203] The closed second vane 15 can create a temperature difference between the surface of the guide panel 152 through which heat-exchanged air flows and the surface of the base panel 154 in contact with the outside air.

[0204] Because the second vane 15 has a thinner thickness compared to the other components of the case, condensation may occur on the surface of the base panel 154 due to the difference in surface temperature between the guide panel 152 and the base panel 154.

[0205] However, the second vane 15 of the present invention can prevent condensation via an insulating member 156 positioned between the guide panel 152 and the base panel 154, as shown in Figure 15.

[0206] The opened second vane 15 can be separated from the discharge guide 122. When the second vane 15 is opened, the distance between it and the discharge guide 122 can be increased. The second inclined portion 1525 of the second vane 15 can be separated from the second guide surface 1224. The airflow flowing through the second discharge channel 1802 can be discharged to the second discharge port 12b (not shown) through the separation gap between the second guide surface 1224 of the discharge guide 122 and the second vane 15. In this way, the opened second vane 15 can adjust the direction of the airflow discharged through the second discharge port 12b (not shown).
