Description

Air conditioner{AIR CONDITIONER}

This disclosure relates to air conditioners.

Generally, an air conditioner consists of a compressor, condenser, evaporator, and expander, and supplies cool or warm air to a building or indoor space using an air conditioning cycle.

Air conditioners are structurally divided into a separate type in which the compressor is placed outdoors, and an integrated type in which the compressor is manufactured as one piece.

The separate type installs an indoor heat exchanger indoors, installs an outdoor heat exchanger and compressor in the outdoor unit, and connects the two separate devices with a refrigerant pipe.

Separate air conditioners are generally classified according to the installation type of the indoor unit.

An indoor unit installed vertically in an indoor space is called a stand-type air conditioner, an indoor unit installed on an indoor wall is called a wall-mounted air conditioner, and an indoor unit installed on the indoor ceiling is called a ceiling-type air conditioner.

The 'air conditioner' disclosed in Korean Patent Publication No. 2022-0106389 includes a case having an inlet and an outlet formed on the side; a front panel forming the front of the case; A blowing fan disposed inside the case; a discharge guide disposed inside the case and guiding air discharged from the blower fan; A side vane disposed at the discharge port; and a drive vane disposed between the discharge guide and the front panel, wherein the drive vane is inserted between a first position where it is drawn forward of the discharge port and implements a diffused wind, and the front panel and the discharge guide. It moves between second positions embodying a frontal wind.

In the conventional air conditioner, there is a problem in that the vane is not able to more delicately control the air flow because it implements only two modes: the vane is pulled out to implement a diffused wind, or the vane is inserted to implement a forward wind.

Additionally, since the discharge guide has a flat inclined surface in a diagonal direction, air blowing from the blower fan is discharged in a diagonal direction along the inclined surface of the discharge guide. Therefore, there is a problem that it is difficult to implement forward wind. Furthermore, there is a problem that side vanes are needed to convert diagonal discharge airflow into forward wind.

Additionally, the drive vane is disposed in a space between the front panel and the discharge guide, and is drawn outward from the space to control the wind direction. Therefore, a separate free space is required for the drive vane to be pulled out to the outside, and there is a risk that it may malfunction or break down when it hits an obstacle such as the user's body or an indoor wall.

In addition, in order for the air discharged from the discharge port formed on the side to be blown forward, there is a limitation that the width of the front panel in the side direction must be smaller than the width of the case in the side direction. In other words, there is a problem in that the width of the front panel in the side direction cannot be made larger than the width in the side direction of the case.

The fixing guide 20 may include a second fixing guide 30 fixed to the inside of the case 10 . The second fixed guide 30 may be a part of the fixed guide 20. For example, the second fixed guide 30 may be at least a portion of the outer end of the fixed guide 20.

The second fixed guide 30 may be disposed at an outer end of the fixed guide 20.

The second fixed guide 30 may be located at an outer end of the first fixed guide. The second fixing guide 30 may be spaced apart from the first fixing guide 40 in the lateral direction. For example, the second fixing guide 30 may be spaced apart from the side or outer end of the first fixing guide 40 in the lateral direction.

The second fixed guide 30 may have a second fixed guide surface 32. The second fixed guide surface 32 may be a part of the fixed guide surface 22. The second fixed guide surface 32 may be located downstream of the air flow path compared to the first fixed guide surface 42. The second fixed guide surface 32 may be located in front of the first fixed guide surface 42. The second fixed guide surface 32 may be spaced apart from the first fixed guide surface 42 in the lateral direction. The second fixed guide surface 32 may be located downstream of the air flow than the first fixed guide surface 42. The first fixed guide surface 42 may be located on an upstream side of the air flow than the second fixed guide surface 32.

The second fixed guide 30 is spaced apart from the first fixed guide 40 on the side, and a bypass 35 may be formed between the second fixed guide 30 and the first fixed guide 40. The bypass 35 can be opened or closed by the moving guide 70.

The extended length of the fixed guide surface 22 may be longer than the extended length of the moving guide surface 72. Each of the extended lengths may be the length of a path through which air blown from the side blower fan 54 flows. The path may be a transverse path. Alternatively, each of the extended lengths may be extended in the front-to-back direction. The length extended in the front-to-back direction may be the length extended in the cross section.

The extended length of the moving guide surface 72 may be longer than the extended length of the side of the front panel 11. Each of the extended lengths may be the length of a path through which air blown from the side blower fan 54 flows. The path may be a transverse path. Alternatively, each of the extended lengths may be extended in the front-to-back direction. The length extended in the front-to-back direction may be the length extended in the cross section.

The front end of the moving guide 70 may be located outside the front end of the rear guide 6 in the horizontal direction. For example, when the moving guide is disposed in the first position, the front end of the moving guide 70 may be located outside the front end of the rear guide 6 in the horizontal direction.

The front outer end of the front panel 11 may be located outside the front side end of the rear guide 6 in the horizontal direction. The front side end of the rear guide 6 may form a side discharge port 142. The front outer end of the front panel 11 may form a side outlet 142. For example, the panel edge 112 may protrude outward in the horizontal direction by a predetermined distance L than the rear guide edge 64.

Referring to FIG. 4, the air conditioner 1 will be described.

Figure 4 shows a forward wind mode according to one embodiment of the present disclosure.

The side blowing fan 54 can flow air introduced through the intake port 152 to the side discharge port 142. Air blown by the side blowing fan 54 may flow through the discharge passage 141 formed between the front guide 2 and the rear guide 6. The blowing air can flow along the front guide (2). The blowing air may flow along the fixed guide 20.

A bypass 35 may be formed between the first fixed guide 40 and the second fixed guide 30. In forward wind mode the bypass 35 can be closed. Air flowing along the fixed guide 20 may not flow into the closed bypass 35, but may flow toward the moving guide surface 72.

In the forward wind mode, the moving guide 70 may be placed in the first position. The front outer end of the moving guide 70 disposed at the first position may be continuous with the side end of the front panel 11. A side edge of the front panel 11 may be a side of the front panel 11. The moving guide 70 disposed at the first position can close the bypass 35.

Air passing through the first fixed guide surface 42 and the second fixed guide surface 32 may flow to the moving guide surface 72. The moving guide surface 72 may be formed convexly. The moving guide surface 72 may be a curved surface formed to be convex outward. Air passing through the fixed guide 20 may flow along the moving guide surface 72. The slope of the moving guide surface 72 may be directed forward as it moves forward. That is, the slope of the front outer end of the moving guide surface 72 can be formed close to the front-back direction. Accordingly, air can be discharged forward along the moving guide surface 72. The flow direction of the discharged air may gradually change from the diagonal direction to the front.

The side end of the front panel 11 may correspond to the front outer end of the moving guide 70. That is, the position of the panel edge 112 may correspond to the position of the moving guide edge 74. Accordingly, the front panel may not obstruct the flow of discharged air.

Referring to FIG. 5, the air conditioner 1 will be described.

Figure 5 is an enlarged view of S1 in Figure 4.

The second fixed guide surface 32 may be located on the extended surface E1 of the first fixed guide surface 42. The angle theta4 formed by the second fixed guide surface 32 with respect to the left and right directions may correspond to the angle theta5 formed by the first fixed guide surface 42 with respect to the left and right directions. That is, the inclined angle theta4 of the second fixed guide surface 32 may correspond to the inclined angle theta5 of the first fixed guide surface 42. Accordingly, the air blown along the first fixed guide surface 42 can flow along the second fixed guide surface 32. Additionally, the second fixed guide surface 32 may not obstruct the flow of air blowing from the first fixed guide surface 42.

The bypass 35 may be formed in the front-to-back direction. The bypass 35 may be inclined with respect to the front-to-back direction. The bypass 35 may be inclined outward toward the front. For example, the bypass 35 may be inclined outward toward the front at a predetermined angle (theta 1).

The bypass 35 may be a flow path formed with a width of a predetermined interval t1. The bypass 35 may be formed to have a constant width in the extending direction. The width may be in a direction perpendicular to the air flow direction. The width may be in a direction perpendicular to the direction in which the bypass 35 extends. For example, the bypass 35 extends in the front-back direction, and the bypass 35 may be a flow path formed at intervals of 5 mm.

The first fixed guide 40 may have a first bypass surface 43 forming a bypass 35 . The first bypass surface 43 may form a side surface of the first fixed guide 40. The side may be a side facing outward. The first bypass surface 43 may extend in the front-to-back direction. The angle at which the first bypass surface 43 is inclined with respect to the front-to-back direction may correspond to the angle at which the bypass 35 is inclined with respect to the front-back direction (theta 1).

The first bypass surface 43 may be bent from the first fixed guide surface 42. The first bypass surface 43 and the first fixed guide surface 42 may form an obtuse angle of a predetermined angle (theta 3).

The second fixed guide 30 may have a second bypass surface 34 forming a bypass 35 . The second bypass surface 34 may form a side surface of the second fixed guide 30. The side may be a side facing inward. The second bypass surface 34 may face the first bypass surface 43.

The second bypass surface 34 can be bent from the second fixed guide surface 32. The second bypass surface 34 and the second fixed guide surface 32 may form an acute angle of a predetermined angle (theta 2). The acute angle of the predetermined angle (theta 2) may be a difference equal to 180 degrees minus the obtuse angle of the predetermined angle (theta 3).

When the moving guide 70 is placed in the first position, the bypass 35 can be closed. Accordingly, the air that has passed through the fixed guide surface does not flow into the bypass, but can be discharged along the moving guide surface.

The moving guide 70 may extend in the front-to-back direction. The moving guide 70 may be formed to have a predetermined thickness (W). The thickness W of the moving guide 70 in the front-back direction may be greater than the front-back thickness of the front panel 11. The thickness W of the moving guide 70 in the front-back direction may be greater than the thickness W of the second fixed guide 30 in the front-back direction.

At least part of the moving guide surface 72 may be a curved surface. The moving guide surface 72 may include a flat portion 722 and a curved portion 724. For example, the moving guide surface 72 may include a flat portion 722 located on the upstream side of the air flow and a curved portion 724 located on the downstream side of the air flow.

The flat portion 722 may extend from the second fixed guide surface 32. For example, when the moving guide 70 is disposed in the first position, the planar portion 722 may extend from the second fixed guide surface 32. The curved portion 724 may extend from the flat portion 722.

At least a portion of the moving guide surface 72 may be formed to be convex outward. The portion may be a curved portion 724. The curved portion 724 may be a convex portion 724. The convex portion 724 may be formed to be convex toward the discharge passage 141. By the moving guide 70 having the Coanda surface 72, the discharge direction of the air flowing in the discharge passage can be changed along the moving guide surface by the Coanda effect. The air flowing along the moving guide surface may change its flow direction from a diagonal direction to a forward direction.

Accordingly, the performance of implementing front wind can be improved.

In addition, since there is no need for a separate vane disposed at the discharge port to form a forward wind, the structure can be simplified and the number of parts can be reduced.

The angle formed by the moving guide surface 72 with respect to the front-back direction may decrease as it moves forward. The angle formed by the flat portion 722 with respect to the front-to-back direction may be constant. The angle formed by the convex portion 724 with respect to the front-back direction may become smaller as it approaches the side discharge port 142. One end of the convex portion 724 may be connected to the flat portion 722, and the other end of the convex portion 724 may form a side discharge port 142. The other end of the convex portion 724 may extend in the front-back direction. That is, the angle formed by the other end of the convex portion 724 with respect to the front-back direction may be 0. Additionally, the inclination of the other end of the convex portion 724 may correspond to the front-to-back direction.

The convex portion 724 may be formed with a predetermined curvature (R1). For example, the radius of curvature R1 of the convex portion 724 may be 30 mm.

The curvature of the moving guide surface 72 may increase as it moves forward. The curvature of the convex portion 724 may increase as it moves forward. The radius of curvature of the convex portion 724 may decrease as it moves forward. Accordingly, the tendency of the discharged air to flow along the fixed guide surface may be increased.

When the moving guide 70 is disposed in the first position, the moving guide surface 72 may be continuous with the second fixed guide surface 32. The flat portion 722 may extend from the second fixed guide surface 32. The flat portion 722 may be located on the extended surface E1 of the second fixed guide surface 32.

When the moving guide 70 is disposed in the first position, the moving guide surface 72 may be continuous with the side of the front panel 11. The side of the front panel 11 may be a panel edge 112. The convex portion 724 may be continuous with the side surface of the front panel 11. The side surface of the front panel 11 extends in the front-to-back direction, and the moving guide surface 72 may be continuous with the side surface of the front panel 11. Accordingly, air blowing from the moving guide surface can be discharged forward along the side of the front panel.

Referring to FIG. 6, the air conditioner 1 will be described.

Figure 6 is a diagram illustrating discharge airflow in front wind mode according to an embodiment of the present disclosure.

Air-conditioned air may be discharged through the side outlet 142. Air discharged along the moving guide surface 72 of the moving guide 70 disposed at the first position may be discharged forward. The discharged air may be discharged at a predetermined angle with respect to the front-to-back direction. For example, the predetermined angle may be approximately 29 degrees.

Accordingly, despite the side outlet 142 formed on the side of the case 10, the air-conditioned air can be discharged forward along the moving guide surface 72 due to the Coanda effect.

Additionally, the forward wind realization performance of the air conditioner can be improved.

Referring to FIG. 7, the air conditioner 1 will be described.

Figure 7 is a cut-away cross-sectional view in an oblique wind mode according to an embodiment of the present disclosure.

When the moving guide 70 is disposed in the second position, the diagonal wind mode of the air conditioner 1 can be implemented. At this time, the discharged air may move linearly in a diagonal direction.

The second location may be spaced laterally inwardly from the first location. When the moving guide 70 moves from the first position to the second position, the moving guides 70 disposed on both sides of the case 10 may become closer to each other. As the moving guide 70 moves to the second position, the discharge flow path 141 may change. When the moving guide 70 is disposed in the second position, the second fixed guide surface 32 and the moving guide surface 72 may be discontinuous. Accordingly, the discharged air may be discharged along the second fixed guide surface 32 and not flow along the moving guide surface 72.

Referring to FIG. 8, the air conditioner 1 will be described.

In diagonal wind mode, the moving guide 70 can move inward in the lateral direction. The distance that the moving guide 70 moves may be the distance d1 between the first position and the second position. For example, when the moving guide 70 moves from the first position to the second position, the moving guide 70 may move 10 mm inward in the lateral direction along the front panel 11.

When the moving guide 70 is placed in the second position, the bypass 35 can be closed. Accordingly, the air blown from the first fixed guide surface does not flow into the bypass, but can flow to the second fixed guide surface.

The length (m1) of the front facing side of the second fixed guide 30 may be longer than the distance (d1) between the first and second positions.

The second fixed guide surface 32 may be inclined outward toward the front. The second fixed guide surface 32 may be inclined at a predetermined angle (theta 1+theta 2) with respect to the front-back direction. The second fixed guide surface 32 may be inclined at a predetermined angle (theta 4) with respect to the side direction. Accordingly, the air discharged along the second fixed guide surface may be discharged at an angle close to the inclined angle of the second fixed guide surface.

The angle at which the second fixed guide surface 32 is inclined with respect to the front-to-back direction (theta 1+theta 2) may be greater than the angle at which the bypass 35 is inclined with respect to the front-back direction (theta 1).

When the moving guide 70 is disposed in the second position, the second fixed guide surface 32 and the moving guide surface 72 may be discontinuous. The flat portion of the moving guide surface 72 and the second fixed guide surface 32 may be discontinuous. The rear end of the moving guide surface 72 may be spaced apart from the front end of the second fixed guide surface 32 by a predetermined distance d1 inward in the lateral direction.

When the moving guide 70 is disposed in the second position, the side of the front panel 11 and the moving guide surface 72 may be discontinuous. The convex portion 724 of the moving guide surface 72 and the side surface of the front panel 11 may be discontinuous. The side of the front panel 11 may be a panel edge 112. The front outer end of the moving guide surface 72 may be spaced apart from the side end of the front panel 11 by a predetermined distance d1 in the lateral direction.

Referring to FIG. 9, the air conditioner 1 will be described.

Figure 9 shows discharge airflow in diagonal wind mode according to an embodiment of the present disclosure.

Air-conditioned air may be discharged through the side outlet 142. Air discharged along the second fixed guide surface 32 may be discharged diagonally. The discharged air may be discharged at a predetermined angle with respect to the front-to-back direction. For example, the predetermined angle may be approximately 35 degrees. Accordingly, since the air flowing in the discharge passage does not flow along the moving guide surface but is discharged directly along the second fixed guide surface, a diagonal wind can be realized.

Oblique wind may be discharged more inclined to the side than forward wind. Accordingly, the range of indoor space to be cooled can be expanded. Additionally, it is possible to indirectly cool the indoor space.

Referring to FIG. 10, the air conditioner 1 will be described.

The moving guide 70 may be placed in a third position. When the moving guide 70 is disposed in the third position, the diffused wind mode of the air conditioner 1 can be implemented.

The third position may be spaced apart from the second position toward the inside of the case 10 in the lateral direction. When the moving guide 70 moves to the third position, the moving guides 70 disposed on both sides of the case 10 may become closer to each other. As the moving guide 70 moves to the third position, the discharge flow path 141 may change. The discharge passage 141 may be divided into a first discharge passage and a second discharge passage. The branched first discharge flow path and the second discharge flow path may be reunited near the discharge port.

When the moving guide 70 is disposed in the third position, the second fixed guide surface 32 and the moving guide surface 72 may be discontinuous. Accordingly, the air flowing along the second fixed guide surface 32 may not flow along the moving guide surface 72.

When the moving guide 70 is placed in the third position, the bypass 35 can be opened.

Referring to FIG. 11, the air conditioner 1 will be described.

In the diffuse wind mode, the moving guide 70 can move inward in the lateral direction. The moving guide 70 can move between the first position and the third position. The distance d2 between the first location and the third location may be longer than the distance d1 between the first location and the second location. For example, the distance between the first and third positions is 17 mm, and the distance between the first and second positions is 10 mm.

The moving guide 70 can move from the first position to the third position. At this time, the distance the moving guide 70 moves may be the distance d2 between the first position and the third position. For example, when the moving guide 70 moves from the first position to the third position, the moving guide may move inward in the lateral direction by 17 mm along the front panel 11.

The moving guide 70 can move from the second position to the third position. At this time, the distance the moving guide moves may be the distance (d2-d1) between the second position and the third position. For example, when the moving guide moves from the second position to the third position, the moving guide may move 7 mm inward in the lateral direction along the front panel 11.

When the moving guide 70 is placed in the third position, the bypass 35 can be opened. As the bypass 35 is opened, a second discharge passage and a second discharge airflow Fm2 flowing through the second discharge passage may be formed. Air flowing along the first fixed guide surface 42 may flow into the bypass 35. Air introduced into the bypass 35 may pass through the bypass 35 and flow along the moving guide surface 72. The moving guide surface 72 can guide air to the front panel 11. Air flowing along the front panel 11 may be discharged in a side direction.

When the moving guide 70 is disposed in the third position, the second fixed guide surface 32 and the moving guide surface 72 may be discontinuous. The flat portion 722 of the moving guide surface 72 and the second fixed guide surface 32 may be discontinuous. The rear end of the moving guide surface 72 may be spaced apart from the front end of the second fixed guide surface 32 inward in the lateral direction by a predetermined distance d2.

The first fixed guide 40 may have a first bypass surface 43 forming a bypass 35 . The first bypass surface 43 may form a side surface of the first fixed guide 40.

The first bypass surface 43 may be continuous with the moving guide surface 72. Accordingly, the air passing through the bypass can be guided to the moving guide surface.

The second fixed guide 30 may have a second bypass surface 34 forming a bypass 35 . The second bypass surface 34 may be located behind the moving guide surface 72. The second bypass surface 34 may be located upstream of the moving guide surface 72.

When the moving guide 70 is disposed in the third position, the side of the front panel 11 and the moving guide surface 72 may be discontinuous. The convex portion 724 of the moving guide surface 72 and the side portion of the front panel 11 may be discontinuous. The side portion of the front panel 11 may be a panel edge 112. The front outer end of the moving guide surface 72 may be spaced apart from the side end of the front panel 11 by a predetermined distance d1 in the lateral direction.

The moving guide surface 72 may be continuous with the rear of the front panel 11. The convex portion 724 of the moving guide surface 72 may be continuous with the rear surface of the front panel 11. Accordingly, air flowing along the moving guide surface can flow along the rear side of the front panel. That is, the moving guide surface can guide the flowing air to the rear of the front panel.

The front panel 11 can guide the air that has passed through the bypass 35. The rear of the front panel 11 can guide the air that has passed through the bypass 35. The rear side of the front panel 11 may extend in the side direction. Accordingly, the second discharge airflow Fm2 flowing along the front panel 11 may flow and be discharged in the side direction.

The first discharge passage may be a path through which air is discharged along the first fixed guide surface 42 and the second fixed guide surface 32. In the second discharge passage, air flowing along the first fixed guide surface 42 flows into the bypass 35, and air passing through the bypass 35 flows through the moving guide surface 72 and the front panel ( 11) may be a path that flows sequentially and is discharged.

The air Fm2 flowing through the second discharge passage may be discharged along the front panel 11 and have a strong tendency to flow in a lateral direction. Air passing through the bypass 35 flows to the moving guide surface 72, and the air flowing along the moving guide surface 72 may be guided to the rear of the front panel 11. Since the front panel 11 extends in the side direction, the air flowing along the front panel 11 may have a strong tendency to flow in the side direction.

The air Fm2 flowing through the second discharge passage may have stronger lateral flow properties than the air Fm1 flowing through the first discharge passage. The air (Fm2) discharged by flowing through the second discharge passage may push the air (Fm1) discharged by flowing through the first discharge passage in the side direction. Accordingly, the air (Fm1) discharged by flowing through the first discharge passage may be combined with the air (Fm2) discharged by flowing through the second discharge passage and further spread in the lateral direction.

Accordingly, the performance of realizing diffused wind of the air conditioner can be improved.

Referring to FIG. 12, the air conditioner 1 will be described.

Figure 12 shows discharge airflow in diffuse wind mode according to an embodiment of the present disclosure.

Air-conditioned air may be discharged through the side outlet 142. The discharged air may be a combination of a first discharge airflow and a second discharge airflow. As the first discharge airflow is further pushed in the side direction by the second discharge airflow, the air conditioner can implement a diffused wind. The discharged air may be discharged at a predetermined angle with respect to the front-to-back direction. For example, the predetermined angle may be approximately 45 degrees. Accordingly, the air discharged through the side discharge port can be further biased toward the side by the second discharge airflow, so a diffused wind can be realized.
