[0001] The present invention relates to an air conditioner, and more particularly, to an air conditioner having one intake port and two exhaust ports.

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

[0003] Wall-mounted air conditioners can have outlets that open either forward or downward. Structures with only one outlet cannot cover a wide area, making it difficult to provide user comfort. Specifically, if the outlet is located forward, it is difficult to form a direct airflow toward the bottom of the air conditioner. If the outlet is located downward, it is difficult to deliver air to a long distance in the front.

[0004] Korean Patent Publication No. KR 2020-0095936 discloses the structure of an air conditioner in which two outlets are formed.

[0005] However, the structure of the above document requires a separate structure for opening and closing each of the two outlets. Furthermore, due to the structure, the forward flow distance of the air discharged may be limited.

[0006] The problem to be solved by the present invention is to provide an air conditioner that sends air over a long distance.

[0007] Another problem to be solved by the present invention is to provide an air conditioner that controls the flow of air discharged through two outlets with one vane.

[0143] The discharge path (18) includes a first discharge path (18a) formed between the first guide (86) and the second guide (102), and a second discharge path (18b) formed between the first inner vein (120) and the second guide (102).

[0144] The second discharge path (18b) can be formed when the first inner vein (120) closes the second discharge port (48).

[0145] The inclination angle (θ1) formed between the first guide (86) and the imaginary horizontal line (HL) that is horizontal to the ground can be formed to be greater than the inclination angle (θ2) formed between the second guide (102) and the imaginary horizontal line (HL).

[0146] That is, the width formed by the cross section of the discharge path (18) formed between the first guide (86) of the inner body (80) and the second guide (102) of the stabilizer (100) can increase as it gets farther away from the fan (50).

[0147] The second guide (102) includes a rear guide (102a), a middle guide (102b) extending forward from the rear guide (102a), and a front guide (102c) extending forward from the middle guide (102b).

[0148] The rear guide (102a) may be arranged to extend forward and downward as it moves away from the fan (50). The rear guide (102a) may have a shape that is inclined forward and downward.

[0149] The rear guide (102a) can form a discharge path (18) with the lower guide (86b) of the first guide (86). The inclination angle (θ2) formed by the rear guide (102a) with the imaginary horizontal line (HL) can be formed to be smaller than the inclination angle (θ1) formed by the first guide (86) with the imaginary horizontal line (HL).

[0150] A portion of the rear guide (102a) is positioned above the first guide (86). Another portion of the rear guide (102a) is positioned above the second discharge port (48). Another portion of the rear guide (102a) is positioned above the first vane (120).

[0151] The length (102aL) of the rear guide (102a) extending in the front-back direction may be formed to be longer than the length (102bL) of the middle guide (102b) extending in the front-back direction. The length (102aL) of the rear guide (102a) extending in the front-back direction may be formed to be shorter than the length (86bL) of the lower guide (86b) of the first guide (86) extending in the front-back direction.

[0152] The middle guide (102b) can be arranged approximately parallel to the ground. The middle guide (102b) is arranged above the second discharge port (48). The middle guide (102b) can be arranged above the first vane (120). The middle guide (102b) is arranged approximately parallel to the first vane (120) with the second discharge port (48) closed.

[0153] The length (102bL) of the middle guide (102b) extending in the forward-backward direction may be formed shorter than the length (120L) of the first vane (120) extending in the forward-backward direction. The length (120aL) of the rear guide (102a) extending in the forward-backward direction may be formed to be 1.5 to 3 times the length (102bL) of the middle guide (102b) extending in the forward-backward direction.

[0154] The angle (θ3) formed between the middle guide (102b) and the rear guide (102a) can be formed to be larger than the angle (θ4) formed between the first guide (86) and the first vane (120) when the second discharge port (48) is closed.

[0155] The length (102bL) of the middle guide (102b) extending in the front-back direction may be formed to be longer than the length (102cL) of the front guide (102c) extending in the front-back direction. The length (102bL) of the middle guide (102b) extending in the front-back direction may be formed to be two to four times the length (102cL) of the front guide (102c) extending in the front-back direction.

[0156] The front guide (102c) can extend forward and downward from the middle guide (102b). The front guide (102c) is connected to the upper part (32) of the discharge cover (30).

[0157] The front guide (102c) is arranged above the second discharge port (48). The front guide (102c) is arranged above the first vane (120).

[0158] The first guide (86) includes an upper guide (86a) that is arranged around the perimeter of the fan (50) and has a banded shape. The upper guide (86a) may be formed so that the gap between it and the fan (50) increases as it goes downward.

[0159] The upper guide (86a) can be positioned higher in the vertical direction than the second guide (102). The upper guide (86a) can guide the air discharged to the rear by the rotation of the fan (50) downward.

[0160] The first guide (86) includes a lower guide (86b) that guides air flowing downward by the rotation of the fan (50) forward. The lower guide (86b) may have a structure extending downwardly forward.

[0161] The first guide (86) can guide air flowing by the rotation of the fan (50) to the second outlet (48). The lower guide (86b) of the first guide (86) has a structure that extends toward the second outlet (48).

[0162] The first vane (120) can be positioned in a closed position with the second outlet (48). The first vane (120) includes a vane upper surface (121) that comes into contact with air flowing by the rotation of the fan (50). The first vane (120) includes a vane lower surface (122) that is positioned opposite to the vane upper surface (121).

[0163] Referring to the drawing, the upper vane surface (121) and the lower vane surface (122) can be formed on different plates. However, unlike the drawing, the upper vane surface (121) and the lower vane surface (122) can also be formed on a single plate.

[0164] The upper surface of the vane (121) can be arranged approximately parallel to the middle guide (102b) of the second guide (102). The upper surface of the vane (121) can come into contact with air flowing along the discharge passage (18). The upper surface of the vane (121) can guide air flowing along the discharge passage (18).

[0165] As shown in Fig. 6, when the first vane (120) closes the second discharge port (48), air flowing through the discharge path (18) can move along the upper vane surface (121) of the first vane (120) and flow to the first discharge port (36).

[0166] As in Fig. 6, the state in which the first vane (120) closes the second outlet (48) can be set as the first position (P1) of the vane. That is, the vane can be arranged so that the first vane (120) closes the second outlet (48) at the first position (P1).

[0167] A plurality of protrusions (121c) protruding upward and spaced apart in the front-back direction may be formed on the upper surface (121) of the first vane (120). The plurality of protrusions (121c) can prevent dew from forming on the upper surface of the first vane (120).

[0168] The rear end (121b) of the upper surface of the vane (121) can form a slope that extends downwards as it goes rearward. The front end (121a) of the upper surface of the vane (121) can form a slope that extends downwards as it goes forward.

[0169] The rear end (121b) may have a front-back length (121bL) that is 0.1 to 0.2 times the front-back length (120L) of the first vane (120). The front end (121a) may have a front-back length (121aL) that is 0.1 to 0.2 times the front-back length (120L) of the first vane (120).

[0170] Insulation material may be placed inside the first vane (120).

[0171] The second vane (130) may be placed above the first vane (120). With the first vane (120) closing the second outlet (48), the second vane (130) may be placed to send air forward.

[0172] At the first position (P1) of the vane, the second vane (130) sends air flowing forward and downward through the discharge passage (18) to the first discharge port (36). At the first position (P1) of the vane, the second vane (130) may be arranged in a downwardly convex shape.

[0173] At the first position (P1) of the vane, the rear end (121b) of the second vane (130) may be positioned so as to face rearward and upward. At the first position (P1) of the vane, the front end (121a) of the second vane (130) may be positioned so as to face forward or forward and upward.

[0174] The length (130L) formed in the front-back direction of the second vane (130) can be formed to be less than half the length (120L) formed in the front-back direction of the first vane (120).

[0175] The discharge cover (30) is arranged at the front of the case (10). The discharge cover (30) may be arranged inside the case (10). A first discharge passage (30a, or 'third discharge passage') that guides air flowing through the discharge passage (18) to the first discharge port (36) may be formed inside the discharge cover (30).

[0176] The first discharge outlet channel (30a) can send air flowing through the second discharge outlet channel (18b) forward and upward. The first discharge outlet channel (30a) can have a shape inclined forward and upward.

[0177] The first discharge outlet passage (30a) can be formed between the upper part of the discharge cover (32) and the lower part of the discharge cover (34). A first discharge port (36) can be formed at the front end of the first discharge outlet passage (30a).

[0178] The lower part of the discharge cover (34) may include an inclined guide wall (34a) that forms a forward-upward slope, and a vane-responding wall (34b) that is arranged to face the first vane (120).

[0179] The inclined guide wall (34a) causes air flowing along the upper surface (121) of the first vane (120) to flow forward and upward. The inclined guide wall (34a) can guide air flowing along the upper surface (121) of the first vane (120) to the first discharge port (36).

[0180] The inclined guide wall (34a) is arranged below the first discharge port (36). The inclined guide wall (34a) is arranged in front of the second discharge port (48). The inclined guide wall (34a) has a structure that extends upwards as it moves farther forward from the second discharge port (48).

[0181] The inclined guide wall (34a) may be arranged to be inclined upwards relative to the surface formed by the upper surface (121) of the first vane (120). That is, the air flowing through the discharge path (18) and along the upper surface of the first vane (120) may be directed upwards. This allows the air discharged through the first discharge port (36) to be discharged in the horizontal direction forward or upwards relative to the horizontal direction forward. This allows the air discharged forward through the first discharge port (36) to be sent to a long distance.

[0182] 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 arranged approximately horizontally.

[0183] The air conditioner of the present invention may include an inclined guide wall (34a) disposed inside the case (10) and guiding air flowing along the first vane (120) to the first discharge port (36). The inclined guide wall (34a) may be a separate component disposed inside the case (10). The inclined guide wall (34a) may be formed integrally with the case (10) and may be disposed in an internal space formed by the case (10).

[0184] The inclined guide wall (34a) can connect one side of the first inner vane (120) with the second discharge port (48) closed and the lower end of the first discharge port (36). The inclined guide wall (34a) can be arranged in front of the second discharge port (48) and under the first discharge port (36). The inclined guide wall (34a) can have a shape inclined forward and upward.

[0185] The vane-responding wall (34b) is positioned to face the front end (121a) of the first vane (120) positioned at the first position (P1). The vane-responding wall (34b) has a structure that extends downwards as it moves farther forward from the second discharge port (48).

[0186] The upper part of the discharge cover (32) can form a roughly horizontal surface. The upper part of the discharge cover (32) can have a structure extending from the second guide (102).

[0187] The front vane (40) is positioned between the lower part (34) of the discharge cover and the upper part (32) of the discharge cover. The front vane (40) extends in the forward and backward direction and can guide the flow of air discharged to the first discharge port (36). The front vane (40) can have a structure that extends upward as it goes forward.

[0188] The angle of inclination (θ5) formed by the front vane (40) with the imaginary horizontal line (HL) can be formed smaller than the angle of inclination (θ6) formed by the lower part of the discharge cover (34) with the imaginary horizontal line (HL). That is, the lower part of the discharge cover (34) is arranged to be more inclined upward as it goes forward relative to the front vane (40).

[0189] The inclination angle (θ5) formed by the front vane (40) with the imaginary horizontal line (HL) can be formed smaller than the inclination angle (θ6) formed by the inclination guide wall (34a) of the lower part of the discharge cover (34) with the imaginary horizontal line (HL).

[0190] The inclination angle (θ5) formed by the front vane (40) with respect to the imaginary horizontal line (HL) may be formed to be greater than the inclination angle (θ7) formed by the upper vane surface (121) of the first vane (120) with respect to the imaginary horizontal line (HL). The inclination angle (θ5) formed by the front vane (40) with respect to the imaginary horizontal line (HL) may be formed to be greater than the inclination angle (θ8) formed by the upper portion (32) of the discharge cover with respect to the imaginary horizontal line (HL).

[0191] The first discharge outlet channel (30a) may be formed so that the cross-sectional area of ​​the channel decreases as it moves forward. The first discharge outlet channel (30a) may be formed so that the vertical spacing between the channels decreases as it moves forward.

[0192] The area of ​​the first discharge port (36) may be formed smaller than the area of ​​the second discharge port (48). Referring to Fig. 6, the gap (36h) formed by the first discharge port (36) in the vertical direction may be formed smaller than the gap (48w) formed by the second discharge port (48) in the front-back direction.

[0193] The air flowing by the rotation of the fan (50) flows forward and downward along the discharge path (18). In addition, the air flowing between the first vane (120) and the second guide (102) can be discharged to the first discharge port (36) through the first discharge port path (30a). The air discharged to the first discharge port (36) through the first discharge port path (30a) can flow forward and upward.

[0194] Therefore, when the vane is at its first position (P1), air can be discharged through the first outlet (36). Referring to Fig. 9, air can be discharged to the front of the case (10) through the first outlet (36) by the operation of the fan (50). At this time, the air discharged through the first outlet (36) can flow to a long distance in the front.

[0195] Referring to Fig. 7, the arrangement of the vane and the flow of air at the second position (P2) of the vane are described.

[0196] The second position (P2) of the vane may be in a state where the second outlet (48) is open. Therefore, in the second position (P2) of the vane, the first vane (120) may be positioned below the second outlet (48). In the second position (P2) of the vane, the first vane (120) may be positioned at a position spaced downward from the second outlet (48). In the second position (P2) of the vane, the first vane (120) may cause the air flowing to the second outlet (48) to flow forward or downward.

[0197] Unlike the drawing, in 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 outlet (48).

[0198] 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 arranged to be inclined downward.

[0199] At the second position (P2) of the vane, the first vane (120) can guide the wind direction of the air flowing to the second outlet (48). At the second position (P2) of the vane, the air discharged to the second outlet (48) can flow forward and downward along the first vane (120).

[0200] At the second position (P2) of the vane, both the first discharge port (36) and the second discharge port (48) are open. At this time, the air flowing through the discharge path (18) can flow downwardly to the second discharge port (48) that is opened downwardly in the forward direction. It is also possible for some of the air to be discharged to the first discharge port (36). However, most of the air can be discharged through the second discharge port (48) and flow downwardly or forwardly along the first vane (120) that is arranged to open the second discharge port (48).

[0201] Referring to Fig. 10, when the vane is positioned at the second position (P2), air discharged through the second discharge port (48) and / or the first discharge port (36) can flow forward downward. Since the main airflow of the discharged air is discharged through the second discharge port (48), the air can be discharged forward downward.

[0202] Referring to Fig. 8, the arrangement of the vane and the flow of air at the third position (P3) of the vane are described.

[0203] The second position (P3) of the vane is a state in which the second discharge port (48) is open. Therefore, in the third position (P3) of the vane, the first vane (120) can be placed below the second discharge port (48). In the second position (P3) of the vane, the lower end of the first vane (120) is placed below the second discharge port (48). In addition, in the second position (P3) of the vane, the upper end of the first vane (120) is placed above the second discharge port (48).

[0204] At the third position (P3) of the vane, the first vane (120) can cause the air flowing to the second outlet (48) to flow below the second outlet (48).

[0205] 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.

[0206] 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.

[0207] At the second position (P3) of the vane, the lower end of the second vane (130) is positioned below the second outlet (48). At the second position (P3) of the vane, the upper end of the second vane (130) is positioned above the second outlet (48).

[0208] When moving from the second position (P2) of the vane to the third position (P3) of the vane, the second vane (130) can move downwards slightly. When moving from the second position (P2) of the vane to the third position (P3) of the vane, the second vane (130) can move downwards while rotating counterclockwise.

[0209] At the third position (P3) of the vane, the first vane (120) can guide the wind direction of the air flowing to the second outlet (48). At the third position (P3) of the vane, the air discharged to the second outlet (48) can flow along the first vane (120) and below the second outlet (48).

[0210] At the third position (P3) of the vane, both the first vane (120) and the second vane (130) are arranged to be inclined downward.

[0211] At the third position (P3) of the vane, both the first discharge port (36) and the second discharge port (48) are open. At this time, the air flowing through the discharge path (18) can flow primarily downwards through the second discharge port (48).

[0212] It is also possible for some of the air to be discharged through the first outlet (36). However, most of the air is discharged through the second outlet (48). In addition, air can flow below the second outlet (48) by the first vane (120) and the second vane (130).

[0213] Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications may be made by a person skilled in the art without departing from the gist of the present invention as claimed in the claims. Furthermore, such modifications should not be understood individually from the technical idea or prospect of the present invention.
