The middle guide 102b can be arranged above the first vane 120. The middle guide 102b is arranged substantially parallel to the first vane 120 in a state where the second discharge port 48 is closed.

[0146] The length 102bL by which the middle guide 102b extends in the front-rear direction can be formed to be shorter than the length 120L by which the first vane 120 extends in the front-rear direction. The length 120aL by which the rear guide 102a extends in the front-rear direction can be formed to be 1.5 to 3 times the length 102bL by which the middle guide 102b extends in the front-rear direction.

[0147] The included angle θ3 formed between the middle guide 102b and the rear guide 102a can be formed to be larger than the included angle θ4 formed between the first guide 86 and the first vane 120 in a state where the second discharge port 48 is closed.

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

[0156] Referring to the drawings, the vane upper surface 121 and the vane lower surface 122 can be formed on different plates from each other. However, different from the drawings, the vane upper surface 121 and the vane lower surface 122 can also be formed on one plate.

[0157] The vane upper surface 121 can be arranged substantially parallel to the middle guide 102b of the second guide 102. The vane upper surface 121 can contact the air flowing along the discharge flow path 18. The vane upper surface 121 can guide the air flowing along the discharge flow path 18.

[0158] Similar to FIG. 6, when the first vane 120 closes the second discharge port 48, the air flowing through the discharge channel 18 can move along the vane upper surface 121 of the first vane 120 and flow into the first discharge port 36.

[0159] Similar to FIG. 6, the state where the first vane 120 closes the second discharge port 48 can be set as the first position P1 of the vane. That is, at the first position P1 of the vane, the first vane 120 can be arranged to close the second discharge port 48.

[0160] On the vane upper surface 121 of the first vane 120, a plurality of protrusions 121c protruding upward and spaced apart in the front-rear direction can be formed. The plurality of protrusions 121c can prevent dew condensation on the upper side of the first vane 120.

The front-rear direction length 121aL of the front end portion 121a can be formed to be 0.1 to 0.2 times the front-rear direction length 120L of the first vane 120.

[0163] A heat insulating material can be arranged inside the first vane 120.

[0164] The second vane 130 can be arranged above the first vane 120. With the first vane 120 closing the second discharge port 48, the second vane 130 can be arranged to send air forward.

[0166] In the first position P1 of the vane, the rearward end portion 121b of the second vane 130 can be arranged to face the upper rear side. In the first position P1 of the vane, the front end portion 121a of the second vane 130 can be arranged to face the front or the upper front side.

[0167] The length 130L formed in the front-rear direction of the second vane 130 can be formed to be half or less of the length 120L formed in the front-rear direction of the first vane 120.

[0168] The discharge cover 30 is arranged at the front portion of the case 10. The discharge cover 30 can be arranged inside the case 10. Inside the discharge cover 30, a first discharge port flow path 30a for guiding the air flowing through the discharge flow path 18 to the first discharge port 36, or a "third discharge flow path" can be formed.

[0169] The first discharge port flow path 30a can send the air flowing through the second discharge flow path 18b to the upper front side. The first discharge port flow path 30a can have a form inclined to the upper front side.

[0170] The first discharge port flow path 30a can be formed between the upper discharge cover portion 32 and the lower discharge cover portion 34. The first discharge port 36 can be formed at the front end portion of the first discharge port flow path 30a.

[0171] The lower discharge cover portion 34 can include an inclined guide wall 34a forming an inclined surface on the upper front side and a vane corresponding wall 34b arranged to face the first vane 120.

[0172] The inclined guide wall 34a causes the air flowing along the vane upper surface 121 of the first vane 120 to flow to the upper front side. The inclined guide wall 34a can guide the air flowing along the vane upper surface 121 of the first vane 120 to the first discharge port 36.

[0173] The inclined guide wall 34a is disposed below the first discharge port 36. The inclined guide wall 34a is disposed in front of the second discharge port 48. The inclined guide wall 34a has a structure that extends upward as it moves away from the second discharge port 48 forward.

[0174] The inclined guide wall 34a can be inclined and disposed above the surface formed by the vane upper surface 121 of the first vane 120. That is, the air flowing through the discharge passage 18 and flowing along the upper surface of the first vane 120 can be made to flow upward. This can cause the air discharged from the first discharge port 36 to be discharged in the forward horizontal direction or above the forward horizontal direction. This can send the air discharged forward through the first discharge port 36 to a long distance.

[0175] The front end of the inclined guide wall 34a can be connected to the edge wall 16 of the case 10. The front end of the inclined guide wall 34a connected to the edge wall 16 of the case 10 can be disposed substantially horizontally.

[0176] The air conditioner of the present invention can be disposed inside the case 10 and include an inclined guide wall 34a that guides the air flowing along the first vane 120 to the first discharge port 36. The inclined guide wall 34a can be a separate configuration disposed inside the case 10. The inclined guide wall 34a can be integrally formed with the case 10 and disposed in the internal space formed by the case 10.

[0177] The inclined guide wall 34a can be connected to one side of the first inner vane 120 in a state where the second discharge port 48 is closed and the lower end of the first discharge port 36. The inclined guide wall 34a is disposed in front of the second discharge port 48 and can be disposed below the first discharge port 36. The inclined guide wall 34a can have a form inclined forward and upward.

[0178] The vane corresponding wall 34b is disposed opposite to the front end portion 121a of the first vane 120 disposed at the first position P1. The vane corresponding wall 34b has a structure that extends downward as it moves away from the second discharge port 48 forward.

[0179] The upper part 32 of the ejection cover can form a substantially horizontal surface. The upper part 32 of the ejection cover can have a structure extending from the second guide 102.

[0180] The front vane 40 is disposed between the lower part 34 of the ejection cover and the upper part 32 of the ejection cover. The front vane 40 extends in the front-rear direction and can guide the flow of air ejected to the first ejection port 36. The front vane 40 can have a structure that extends upward as it goes forward.

[0181] The inclination angle θ5 formed by the front vane 40 and the virtual horizontal line HL can be formed smaller than the inclination angle θ6 formed by the lower part 34 of the ejection cover and the virtual horizontal line HL. That is, the lower part 34 of the ejection cover is arranged to be more inclined upward as it goes forward than the front vane 40.

[0182] The inclination angle θ5 formed by the front vane 40 and the virtual horizontal line HL can be formed smaller than the inclination angle θ6 formed by the inclined guide wall 34a of the lower part 34 of the ejection cover and the virtual horizontal line HL.

[0183] The inclination angle θ5 formed by the front vane 40 and the virtual horizontal line HL can be formed larger than the inclination angle θ7 formed by the upper surface 121 of the vane of the first vane 120 and the virtual horizontal line HL. The inclination angle θ5 formed by the front vane 40 and the virtual horizontal line HL can be formed larger than the inclination angle θ8 formed by the upper part 32 of the ejection cover and the virtual horizontal line HL.

[0184] The cross-sectional area of the first ejection port flow path 30a can be formed smaller as it goes forward. The vertical separation distance of the first ejection port flow path 30a can be formed smaller as it goes forward.

[0185] The area of the first ejection port 36 can be formed smaller than the area of the second ejection port 48. Referring to FIG. 6, the interval 36h formed by the first ejection port 36 in the vertical direction can be formed smaller than the interval 48w formed by the second ejection port 48 in the front-rear direction.

[0186] The air flowing due to the rotation of the fan 50 flows forward and downward along the discharge channel 18. Also, the air flowing between the first vane 120 and the second guide 102 can be discharged to the first discharge port 36 via the first discharge port channel 30a. The air discharged to the first discharge port 36 via the first discharge port channel 30a can flow forward and upward.

[0187] Therefore, when the vane is at the first position P1, air can be discharged through the first discharge port 36. Referring to FIG. 9, air can be discharged forward of the case 10 through the first discharge port 36 by the operation of the fan 50. At this time, the air discharged from the first discharge port 36 can flow forward to a long distance.

[0188] Referring to FIG. 7, the arrangement of the vane and the air flow at the second position P2 of the vane will be described.

[0189] The second position P2 of the vane may be in a state where the second discharge port 48 is open. Therefore, at the second position P2 of the vane, the first vane 120 can be disposed below the second discharge port 48. At the second position P2 of the vane, the first vane 120 can be disposed at a position spaced downward from the second discharge port 48. At the second position P2 of the vane, the first vane 120 can cause the air flowing to the second discharge port 48 to flow forward and downward or downward.

[0190] Unlike the figure, at the second position P2 of the vane, it is also possible for a part of the first vane 120 to be located above the second discharge port 48.

[0191] When moving from the first position P1 of the vane to the second position P2 of the vane, the second vane 130 can move downward. When moving from the first position P1 of the vane to the second position P2 of the vane, the second vane 130 can be disposed inclined downward.

[0192] In the second position P2 of the vane, the first vane 120 can guide the air flow direction of the air flowing into the second discharge port 48. In the second position P2 of the vane, the air discharged into the second discharge port 48 can flow forward and downward along the first vane 120.

[0193] In the second position P2 of the vane, both the first discharge port 36 and the second discharge port 48 are opened. At this time, the air flowing through the discharge flow path 18 can flow into the second discharge port 48 whose main flow direction is opened forward and downward. It is also possible for some air to be discharged from the first discharge port 36. However, most of the air is discharged through the second discharge port 48 and can flow forward and downward or downward along the first vane 120 arranged to open the second discharge port 48.

[0194] Referring to FIG. 10, when the vane is arranged at the second position P2, the air discharged into the second discharge port 48 and / or the first discharge port 36 can flow forward and downward. Since the main air flow of the discharged air is discharged through the second discharge port 48, the air can be discharged forward and downward.

[0195] Referring to FIG. 8, the arrangement of the vane and the air flow at the third position P3 of the vane will be described.

[0196] The second position P3 of the vane is a state where the second discharge port 48 is opened. Therefore, at the third position P3 of the vane, the first vane 120 can be arranged below the second discharge port 48. At the second position P3 of the vane, the lower end of the first vane 120 is arranged below the second discharge port 48. Also, at the second position P3 of the vane, the upper end of the first vane 120 is arranged above the second discharge port 48.

[0197] In the third position P3 of the vane, the first vane 120 can cause the air flowing into the second discharge port 48 to flow below the second discharge port 48.

[0198] When moving from the second position P2 of the vane to the third position P3 of the vane, the rear end of the first vane 120 can move upward. When moving from the second position P2 of the vane to the third position P3 of the vane, the front end of the first vane 120 can move downward.

[0199] When moving from the second position P2 of the vane to the third position P3 of the vane, the first vane 120 can move while rotating counterclockwise.

[0200] At the second position P3 of the vane, the lower end of the second vane 130 is disposed below the second discharge port 48. At the second position P3 of the vane, the upper end of the second vane 130 is disposed above the second discharge port 48.

[0201] When moving from the second position P2 of the vane to the third position P3 of the vane, the second vane 130 can partially move downward. When moving from the second position P2 of the vane to the third position P3 of the vane, the second vane 130 can move downward while rotating counterclockwise.

[0202] At the third position P3 of the vane, the first vane 120 can guide the wind direction of the air flowing into the second discharge port 48. At the third position P3 of the vane, the air discharged from the second discharge port 48 can flow along the first vane 120 and below the second discharge port 48.

[0203] At the third position P3 of the vane, all of the first vane 120 and the second vane 130 are inclined in the downward direction.

[0204] At the third position P3 of the vane, both the first discharge port 36 and the second discharge port 48 are opened. At this time, the air flowing through the discharge flow path 18 can flow with the main flow direction below the second discharge port 48.

[0205] Some of the air can also be discharged from the first discharge port 36. However, most of the air is discharged through the second discharge port 48. Further, air can flow under the second discharge port 48 by the first vane 120 and the second vane 130.

[0206] In the above, the preferred embodiments of the present invention have been shown and described. However, the present invention is not limited to the specific embodiments described above, and various modifications can be made by those having ordinary knowledge in the technical field to which the invention pertains without departing from the gist of the invention claimed in the claims.
