[0002] An air conditioner can supply heat-exchanged air to an indoor space to adjust the temperature of the indoor space.

[0003] An air conditioner installed on a wall surface may be formed with a discharge port that opens forward or downward. Since a structure having only one discharge port cannot cover a large area, it is difficult to achieve user satisfaction with comfort. That is, there is a problem that when the discharge port is formed forward, it is difficult to form a direct blowing air flow discharged to the lower part of the air conditioner, and when the discharge port is formed downward, it is difficult to transmit air far forward.

[0004] In Korean Patent Publication No. KR2020-0095936, a structure of an air conditioner having two discharge ports is disclosed.

[0005] However, in the structure of the above-mentioned document, a structure for separately opening and closing two discharge ports needs to be separately configured. In addition, in terms of structure, the flow distance of the air discharged forward may be limited. Summary of the Invention

[0006] The problem to be solved by the present invention is to provide an air conditioner that blows air far away.

[0007] Another problem to be solved by the present invention is to provide an air conditioner that adjusts the flow of air discharged to two discharge ports using one blade.

[0151] The length 102bL of the intermediate guide member 102b extending in the front-rear direction can be formed to be shorter than the length 120L of the first blade 120 extending in the front-rear direction. The length 120aL of the rear guide member 102a extending in the front-rear direction can be formed to be 1.5 to 3 times the length 102bL of the intermediate guide member 102b extending in the front-rear direction.

[0152] The included angle θ3 formed by the intermediate guide member 102b and the rear guide member 102a can be formed to be larger than the included angle θ4 formed by the first guide member 86 and the first blade 120 in a state where the second discharge port 48 is closed.

[0153] The length 102bL of the intermediate guide member 102b extending in the front-rear direction can be formed to be longer than the length 102cL of the front guide member 102c extending in the front-rear direction. The length 102bL of the intermediate guide member 102b extending in the front-rear direction can be formed to be 2 to 4 times the length 102cL of the front guide member 102c extending in the front-rear direction.

The first vane 120 includes an upper vane surface 121 that contacts the air flowing through the rotation of the fan 50. The first vane 120 includes a lower vane surface 122 disposed in a direction opposite to the upper vane surface 121.

[0161] Referring to the drawings, the upper vane surface 121 and the lower vane surface 122 can be formed on different plates from each other. However, differently from the drawings, the upper vane surface 121 and the lower vane surface 122 can be formed on one plate.

[0162] The upper vane surface 121 can be disposed substantially parallel to the intermediate guide member 102b of the second guide member 102. The upper vane surface 121 can contact the air flowing along the discharge flow path 18. The upper vane surface 121 can guide the air flowing along the discharge flow path 18.

[0163] As Figure 6 shown, in a state where the first vane 120 closes the second discharge port 48, the air flowing in the discharge flow path 18 can move along the upper vane surface 121 of the first vane 120 and flow toward the first discharge port 36.

[0164] As Figure 6 shown, a state where the first vane 120 closes the second discharge port 48 can be set as a first position P1 of the vane. That is, in the first position P1 of the vane, the first vane 120 can be disposed to close the second discharge port 48.

[0165] A plurality of protrusions 121c protruding upward and spaced in the front-rear direction can be formed on the upper vane surface 121 of the first vane 120. The plurality of protrusions 121c can prevent dew condensation on the upper side of the first vane 120.

[0168] Heat insulating material may be disposed inside the first blade 120.

[0169] The second blade 130 may be disposed above the first blade 120. In a state where the first blade 120 closes the second discharge port 48, the second blade 130 may be configured to convey air forward.

[0170] At the first position P1 of the blade, the second blade 130 conveys the air flowing forward and downward through the discharge flow path 18 to the first discharge port 36. At the first position P1 of the blade, the second blade 130 may be configured in a shape protruding downward.

[0172] The length 130L of the second blade 130 formed in the front-rear direction may be formed to be half or less of the length 120L of the first blade 120 formed in the front-rear direction.

[0173] The discharge cover 30 is disposed at the front portion of the housing 10. The discharge cover 30 may be disposed inside the housing 10. Inside the discharge cover 30, a first discharge port flow path (or “third discharge flow path”) 30a for guiding the air flowing in the discharge flow path 18 to the first discharge port 36 may be formed.

[0174] The first discharge port flow path 30a may convey the air flowing through the second discharge flow path 18b forward and upward. The first discharge port flow path 30a may have a shape inclined forward and upward.

[0175] The first discharge port flow path 30a may be formed between the upper portion 32 of the discharge cover and the front guiding portion 34. At the front end of the first discharge port flow path 30a, a first discharge port 36 may be formed.

[0176] The front guiding portion 34 may include: an upper guiding portion 34a, which forms an inclined surface forward and upward; and a lower guiding portion 34b, which is disposed facing the first blade 120.

[0177] The upper guiding portion 34a causes the air flowing along the upper surface 121 of the blade of the first blade 120 to flow forward and upward. The upper guiding portion 34a may guide the air flowing along the upper surface 121 of the blade of the first blade 120 to the first discharge port 36.

[0178] The upper guiding portion 34a is disposed below the first discharge port 36. The upper guiding portion 34a is disposed in front of the second discharge port 48. The upper guiding portion 34a has a structure that extends upward more as it is farther from the second discharge port 48 forward.

[0179] The upper guide portion 34a may be configured to be more inclined upward than the plane formed by the blade upper surface 121 of the first blade 120. That is, the air flowing through the discharge flow path 18 and flowing along the upper surface of the first blade 120 can be made to flow upward. In this way, the air discharged through the first discharge port 36 can be discharged forward in a horizontal direction or in a direction more upward than the horizontal direction forward. In this way, the air discharged forward through the first discharge port 36 can be transported to a distance.

[0180] The front end portion of the upper guide portion 34a may be connected to the edge wall 16 of the housing 10. The front end portion of the upper guide portion 34a connected to the edge wall 16 of the housing 10 may be configured to be substantially horizontal.

[0181] The air conditioner according to the present invention may include an upper guide portion 34a disposed inside the housing 10 and guiding the air flowing along the first blade 120 toward the first discharge port 36. The upper guide portion 34a may be a separate component disposed inside the housing 10. The upper guide portion 34a may be a component formed integrally with the housing 10 and disposed in the internal space formed by the housing 10.

[0182] The upper guide portion 34a may connect one side of the first blade 120 in a state of closing the second discharge port 48 and the lower end of the first discharge port 36. The upper guide portion 34a may be disposed in front of the second discharge port 48 and may be disposed below the first discharge port 36. The upper guide portion 34a may have a shape inclined upward and forward.

[0183] The lower guide portion 34b is disposed facing the front end portion 121a of the first blade 120 disposed at the first position P1. The lower guide portion 34b has a structure that extends downward more as it moves forward away from the second discharge port 48.

[0184] The upper discharge cover 32 may form a substantially horizontal plane. The upper discharge cover 32 may have a structure extending from the second guide member 102.

[0185] The front blade 40 is disposed between the front guide portion 34 and the upper discharge cover 32. The front blade 40 extends in the front-rear direction and can guide the flow of the air discharged through the first discharge port 36. The front blade 40 may have a structure that extends upward more as it approaches the front.

[0186] The inclination angle θ5 formed by the front blade 40 and the imaginary horizontal line HL may be formed to be smaller than the inclination angle θ6 formed by the front guide portion 34 and the imaginary horizontal line HL. That is, the front guide portion 34 is configured to be more inclined upward as it approaches the front than the front blade 40.

[0187] The inclination angle θ5 formed by the front blade 40 and the imaginary horizontal line HL can be formed to be smaller than the inclination angle θ6 formed by the upper guiding portion 34a of the front guiding portion 34 and the imaginary horizontal line HL.

[0188] The inclination angle θ5 formed by the front blade 40 and the imaginary horizontal line HL can be formed to be larger than the inclination angle θ7 formed by the upper blade surface 121 of the first blade 120 and the imaginary horizontal line HL. The inclination angle θ5 formed by the front blade 40 and the imaginary horizontal line HL can be formed to be larger than the inclination angle θ8 formed by the upper portion 32 of the discharge cover and the imaginary horizontal line HL.

[0189] The first discharge port flow path 30a can be formed such that the cross-sectional area of the flow path becomes smaller as it gets closer to the front. The first discharge port flow path 30a can be formed such that the vertical separation interval becomes smaller as it gets closer to the front.

[0190] The area of the first discharge port 36 can be formed to be smaller than the area of the second discharge port 48. Refer to Figure 6 and the interval 36h formed by the first discharge port 36 in the vertical direction can be formed to be smaller than the interval 48w formed by the second discharge port 48 in the front-rear direction.

[0191] The air flowing through the rotation of the fan 50 flows forward and downward along the discharge flow path 18. In addition, the air flowing between the first blade 120 and the second guide member 102 can be discharged to the first discharge port 36 via the first discharge port flow path 30a. The air discharged to the first discharge port 36 via the first discharge port flow path 30a can flow forward and upward.

[0192] Therefore, at the first position P1 of the blade, the air can be discharged via the first discharge port 36. Refer to Figure 9 and through the operation of the fan 50, the air can be discharged forward of the housing 10 via the first discharge port 36. At this time, the air discharged to the first discharge port 36 can flow forward to a long distance.

[0193] Refer to Figure 7 and describe the blade configuration and air flow at the second position P2 of the blade.

[0194] The second position P2 of the blade can be a state where the second discharge port 48 is open. Therefore, at the second position P2 of the blade, the first blade 120 can be disposed below the second discharge port 48. At the second position P2 of the blade, the first blade 120 can be disposed at a position separated downward from the second discharge port 48. At the second position P2 of the blade, the first blade 120 can cause the air flowing toward the second discharge port 48 to flow forward and downward or downward.

[0195] Unlike the attached drawings, at the second position P2 of the blade, a part of the first blade 120 may also be located at a position higher than the second discharge port 48.

[0196] When moving from the first position P1 of the blade to the second position P2 of the blade, the second blade 130 may move downward. When moving from the first position P1 of the blade to the second position P2 of the blade, the second blade 130 may be configured to incline downward.

[0197] At the second position P2 of the blade, the first blade 120 may guide the wind direction of the air flowing toward the second discharge port 48. At the second position P2 of the blade, the air discharged to the second discharge port 48 may flow downward and forward along the first blade 120.

[0198] At the second position P2 of the blade, both the first discharge port 36 and the second discharge port 48 are open. At this time, the main flow direction of the air flowing in the discharge flow path 18 may be to flow downward and forward to the second discharge port 48 that is open downward. A part of the air may also be discharged to the first discharge port 36. However, most of the air may be discharged through the second discharge port 48 and may flow downward and forward or downward along the first blade 120 configured to open the second discharge port 48.

[0199] Refer to Figure 10 , when the blade is disposed at the second position P2, the air discharged to the second discharge port 48 and / or the first discharge port 36 may flow downward and forward. Since the main air flow of the discharged air is discharged through the second discharge port 48, the air may be discharged downward and forward.

[0200] Refer to Figure 8 , and describe the configuration of the blade and the flow of air at the third position P3 of the blade.

[0201] The third position P3 of the blade is a state where the second discharge port 48 is open. Therefore, at the third position P3 of the blade, the first blade 120 may be disposed below the second discharge port 48. At the third position P3 of the blade, the lower end of the first blade 120 is disposed below the second discharge port 48. In addition, at the third position P3 of the blade, the upper end of the first blade 120 is disposed above the second discharge port 48.

[0202] At the third position P3 of the blade, the first blade 120 may cause the air flowing toward the second discharge port 48 to flow downward below the second discharge port 48.

[0203] When moving from the second position P2 of the blade to the third position P3 of the blade, the rear end of the first blade 120 may move upward. When moving from the second position P2 of the blade to the third position P3 of the blade, the front end of the first blade 120 may move downward.

[0204] When moving from the second position P2 of the blade to the third position P3 of the blade, the first blade 120 can rotate and move in a counterclockwise direction.

[0205] In the third position P3 of the blade, the lower end of the second blade 130 is disposed below the second discharge port 48. In the third position P3 of the blade, the upper end of the second blade 130 is disposed above the second discharge port 48.

[0206] When moving from the second position P2 of the blade to the third position P3 of the blade, a part of the second blade 130 can move downward. When moving from the second position P2 of the blade to the third position P3 of the blade, the second blade 130 can rotate in a counterclockwise direction and move downward.

[0207] In the third position P3 of the blade, the first blade 120 can guide the wind direction of the air flowing toward the second discharge port 48. In the third position P3 of the blade, the air discharged to the second discharge port 48 can flow along the first blade 120 toward below the second discharge port 48.

[0208] In the third position P3 of the blade, both the first blade 120 and the second blade 130 are disposed to be inclined downward.

[0209] In the third position P3 of the blade, both the first discharge port 36 and the second discharge port 48 are open. At this time, the main flow direction of the air flowing in the discharge flow path 18 can flow toward below the second discharge port 48.

[0210] A part of the air can also be discharged to the first discharge port 36. However, most of the air is discharged through the second discharge port 48. In addition, the air can flow toward below the second discharge port 48 via the first blade 120 and the second blade 130.
