[0001] The present invention relates to an air conditioner, and more particularly to an air conditioner provided with a vane (blade) to which a heat insulating member is coupled. An air conditioner is also called an air conditioner, an air conditioning device, an air conditioning (regulation) unit, a cooling and heating and 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 said Korean patent application. For reference, the contents of the specification, claims and drawings of the said Korean patent application are incorporated into a part of this application specification.

Background Art

[0003] An air conditioner is a device that adjusts the indoor air temperature to the temperature set by the user, and is a device that cools and heats the indoor air according to the principle of the refrigeration cycle. In particular, an indoor unit that is installed vertically in an indoor space 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 a suction port and a discharge port, a heat exchanger that cools the indoor air sucked through the suction port, and a cross-flow fan that sucks the indoor air through the suction port and discharges the cooled air to the discharge port, and a blade disposed at the discharge port to control the wind direction of the discharged air flow, and both ends of the blade are formed sharply, and 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] In addition, since the spaces formed inside both ends of the blade of the conventional air conditioner are not uniform, there is a problem that it is difficult to arrange a heat insulating member with low stretchability.

[0062] Referring to FIG. 1, the air conditioner 1 will be described.

[0063] The air conditioner 1 can include a case 10 in which a suction port 11 and a discharge port 12 are formed. The case 10 can form the outer shape of the air conditioner 1. The case 10 can extend long. The case 10 can form an internal space in which a refrigeration cycle device is accommodated.

[0064] The case 10 can include a front wall 102 that forms a front surface. The front wall 102 can face the indoor space. The front wall 102 can face forward. The case 10 can include side walls 104 that form side surfaces. The side walls 104 can cover the side surfaces of the case 10. The side walls 104 can be connected to the front wall 102. The side walls 104 can include a pair of side walls 104 bent from the front wall 102.

[0065] The suction port 11 can be formed in the case 10. The suction port 11 can be formed on one surface of the case 10. For example, the suction port 11 can be opened on the upper surface of the case 10. The suction port 11 can be opened upward in the case 10. Thereby, indoor air can flow into the inside of the case 10 through the suction port 11.

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

[0067] The air inside the case 10 can be discharged into the indoor space through the discharge port 12. Also, the air that has flowed in through the suction port 11 can be discharged through the discharge port 12. For example, the air inside the case 10 can be discharged forward of the air conditioner 1 through the first discharge port 12a.

[0068] The air conditioner 1 can include a filter 20 disposed at the suction inlet 11. The filter 20 can be formed in a shape corresponding to the shape of the suction port 11. The filter 20 can purify the air flowing into the suction inlet 11.

[0069] The air conditioner 1 can include a vane disposed at the discharge port 12. The vane can guide the airflow discharged through the discharge port 12. The vane can extend long in the longitudinal direction of the discharge port 12.

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

[0071] The air conditioner 1 can include a display 14 for displaying operation information. The display 14 can represent various information. For example, the display 14 can represent information regarding room temperature, set temperature, wind strength, wind direction, indoor humidity, etc. The display 14 can be disposed in the case 10. For example, the display 14 can be disposed on the front wall 102. The display 14 can be coupled to the rear side of the front wall 102. The light emitted through the display 14 can pass through the front wall 102. Thereby, the display 14 can display various information to the user.

[0072] Referring to FIG. 2, the components disposed inside the air conditioner 1 will be described. The air conditioner 1 can include an indoor heat exchanger 16, a blower fan 17, and a guide structure forming a discharge flow path 180.

[0073] The air conditioner 1 can include an indoor heat exchanger 16 disposed 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 suction port 11 and the refrigerant. The air heat-exchanged 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 air flow 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 functions as an evaporator and can supply cold air to the indoor space. For example, the indoor heat exchanger 16 functions as a condenser and can supply warm air to the indoor space.

[0074] The air conditioner 1 can include a blower fan 17 disposed inside the case 10. The blower fan 17 can form an air flow flowing from the suction port 11 to the discharge port 12. The air flow formed by the blower fan 17 can be heat-exchanged with the refrigerant in the indoor heat exchanger 16.

[0075] The blower fan 17 can be disposed adjacent to the indoor heat exchanger 16. For example, the blower fan 17 can be located downstream of the indoor heat exchanger 16 in the air flow direction. However, it is not limited thereto, and the blower fan 17 may be located upstream of the indoor heat exchanger 16 in the air flow direction.

[0076] The case 10 may be formed with a discharge flow path 180 through which the air flow formed by the blower fan 17 flows. The discharge flow path 180 can be located downstream of the blower fan 17 in the air flow direction. The discharge flow path 180 can be located downstream of the indoor heat exchanger 16 in the air flow direction. The air flow that has passed through the indoor heat exchanger 16 or the blower fan 17 can flow to the discharge port 12 through the discharge flow path 180. The discharge flow path 180 can be connected to the discharge port 12.

[0077] The air conditioner 1 can include a front guide 184 that forms a discharge flow path 180. The front guide 184 can be disposed inside the case 10. The front guide 184 can separate the indoor heat exchanger 16 from the discharge flow path 180. The front guide 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 184 can be disposed below the indoor heat exchanger 16.

[0078] The front guide 184 can be disposed adjacent to the discharge port 12. The front guide 184 can extend from the blower fan 17 toward the discharge port 12. For example, the front guide 184 can extend from the blower fan 17 toward the first discharge port 12a. The front guide 184 can extend in a bent manner. Thereby, the discharged air flow can flow smoothly.

[0079] The air conditioner 1 can include a middle guide 181 that is separated from the front guide 184. The middle guide 181 can be disposed inside the case 10. The blower fan 17 can be disposed between the middle guide 181 and the front guide 184. The middle guide 181 can guide the air flow that has passed through the blower fan 17 into the discharge flow path 180. For example, the middle guide 181 is separated rearward from the front guide 184, and the blower fan 17 is located between the front guide 184 and the middle guide 181 to form an air flow. The middle guide 181 can extend in a bent manner in the rotation direction of the blower fan 17.

[0080] The air conditioner 1 can include a rear guide 182 that forms the discharge flow path 180. The discharge flow path 180 can be formed between the front guide 184 and the rear guide 182. The rear guide 182 can be separated from the front guide 184. For example, the rear guide 182 can be separated rearward from the front guide 184.

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

[0082] The discharge port 12 can include a second discharge port 12b (not shown) that opens downward in the case 10. The second discharge port 12b (not shown) can be formed in the lower side wall 106 of the case 10. The second discharge port 12b (not shown) can be adjacent to the first discharge port 12a. For example, the first discharge port 12a opens forward in the front wall 102 of the case 10, and the second discharge port 12b (not shown) can open downward in the lower side wall 106 of the case 10. Thereby, the discharged air can be discharged forward and downward via the first discharge port 12a and the second discharge port 12b (not shown), respectively.

[0083] The vanes can include second vanes 15 disposed at the second discharge port 12b (not shown). The second vanes 15 can open or close the second discharge port 12b (not shown).

[0084] The air conditioner 1 can include a guide module 30 disposed in the discharge flow path 180. The guide module 30 can include a plurality of guide vanes (see FIG. 5, 32, 34). The guide module 30 can guide the flow direction of the airflow flowing through the discharge flow path 180. For example, the guide module 30 can guide the flow direction of the airflow flowing through the discharge flow path 180 in the left-right direction. Thereby, the direction of the airflow discharged into the indoor space can be controlled more precisely.

[0085] The guide module 30 can be coupled to the rear guide 182. The guide module 30 can be disposed between the rear guide 182 and the front guide 184. A plurality of guide vanes (see FIG. 5, 32, 34) are movable in the left - right direction. The guide module 30 can be located downstream of the air - blowing fan 17 in the air - flow direction. The guide module 30 can be positioned between the discharge port 12 and the air - blowing fan 17 on the air - flow path.

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

[0087] The air conditioner 1 can include a radar module 40 that senses the occupants in the indoor space. The radar module 40 can sense the bio - signals in the indoor space. For example, the radar module 40 can sense the position of the occupants, the number of occupants, the activity level, the movement of the occupants, the respiratory rate of the occupants, the body temperature of the occupants, the physical state of the occupants, the posture of the occupants, etc. The air conditioner 1 can be controlled according to at least one of the wind strength, wind direction, and set temperature in response to the sensed bio - signal result value.

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

[0089] The radar sensor 44 can be arranged inside the case 10. The radar sensor 44 can be arranged adjacent to the electrical component section 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 arranged, and a second internal space where the electrical component section 50 is arranged. The radar sensor 44 can be arranged in the second internal space. The radar sensor 44 can be arranged between the indoor heat exchanger 16 and the electrical component section 50.

[0090] The radar sensor 44 can be arranged on the front surface of the case 10. The radar sensor 44 can be arranged on the front wall 102 of the case 10. The radar sensor 44 can be arranged on the back surface 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 a biological signal in the indoor space by transmitting and / or receiving radio waves that penetrate the front wall 102.

[0091] The radar sensor 44 can be arranged in the direction of the indoor space. The radar sensor 44 can be arranged in the forward direction. The radar sensor 44 can be arranged so as to face the front wall 102.

[0092] The air conditioner 1 can include the electrical component section 50. The electrical component section 50 can be arranged in the second internal space of the case 10. The electrical component section 50 can be arranged separated from the indoor heat exchanger 16 and / or the blower fan 17.

[0093] The display 14 can be arranged in front of the electrical component section 50. The display 14 can be arranged on the rear side of the front wall 102. The display 14 can be arranged between the electrical component section 50 and the front wall 102.

Due to the change in the thickness of the first movable portion 3461, a step may not be formed between the connecting portion 344 and the movable portion 346. Thereby, the air flow flowing along the guide vanes 32 and 34 can flow smoothly.

[0136] The second guide vane 34 can include a coupling slot 3463 in which the link 36 is disposed. The coupling slot 3463 can be formed in the movable part 346.
