1 to 3, the air conditioner according to the present embodiment includes a main body 10 disposed between a ceiling 1 and a ceiling finishing material 2 disposed below the ceiling 1, (12) and a heat exchanger (14) provided around the blower (12) inside the main body (10).

The main body 10 is a box body having a substantially rectangular parallelepiped or cubic shape. In another example, the bottom surface of the main body 10 is opened, and the front panel 110 can form the bottom surface of the main body 10.

The main body 10 is formed with a suction port 105, which is a passage through which outside air is sucked, and a discharge port 112 through which heat-exchanged air is discharged. Specifically, one surface of the main body 10 is opened, and a suction port 105 and a discharge port 112 are formed. The suction port 105 and the discharge port 112 are formed in the front panel 110 forming the bottom surface of the main body 10. [ The suction port 105 and the discharge port 112 will be described later.

Inside the main body 10, there is disposed a blower 12 for sucking indoor air and discharging it, and a heat exchanger 14 for exchanging heat with the sucked air.

The heat exchanger 14 is a place where the refrigerant cooled in the outdoor unit in the outside exchanges heat with the room air. The heat exchanger 14 is connected to the outdoor unit by a pipe and the heat exchanger 14 is designed to have a structure for efficiently exchanging the refrigerant inside the pipe with the room air.

The air conditioner according to the present embodiment can be composed of a one-way air conditioner having one air inlet 105 and one air outlet 112. The air conditioner has one air inlet 105 and four air outlet 112 Way air conditioner. In the case of a one-way air conditioner, the blower 12 and the heat exchanger 14 are disposed right and left or front and rear in the main body 10, and when the air conditioner is a 4way air conditioner, the heat exchanger 14 surrounds the blower 12, (12). Hereinafter, a 4way air conditioner will be described as an example.

At this time, a drain pan (18) for receiving condensed water generated in the heat exchanger (14) is formed in the main body (10).

The blower 12 sucks the outside air and discharges it to the discharge port 112 through the heat exchanger 14. [ The fan 12 is composed of a centrifugal blower 12 for sucking the lower air and blowing it around the fan 10 and a fan motor 15 installed on the upper plate of the main body 10 with the rotary shaft 151 protruded downward, And a centrifugal fan 16 connected to the rotary shaft 151 of the rotary shaft 15.

The bell mouth 17 guides the air sucked through the suction port 105 to the blower 12. That is, when the indoor air is sucked, the air is concentrated on the rotary shaft of the blower 12 to perform the function of the orifice to adjust the flow rate or the flow rate of the air.

The bell mouth 17 is in the form of a ring having an opening formed therein, and its width can be reduced as it goes from the front F in the axial direction to the rear R in the axial direction. The central axis of the bell mouth 17 can be overlapped with the rotation axis of the blower 12.

The heat exchanger 14 is composed of front, rear, left, and right portions surrounding the circumference of the blower 12.

The lower portion of the main body 10 is provided with a front panel 110 covering the installation holes of the main body 10 formed on the ceiling finishing material 2 and forming the bottom surface of the air conditioner.

The front panel 110 is provided with a suction port 105 opened to suck indoor air into the main body 10 at a lower side of the blower 12 and has a front, And a discharge port 112 is formed separately on the right side.

The front panel 110 may include a suction port 105 and a discharge port 112 and may include a discharge panel (not shown) having a discharge port 112 and a suction panel (not shown) formed with a suction port 105 It is also possible.

It is preferable that the position of the suction port 105 is positioned so as to vertically overlap with the blower 12. That is, the rotation axis 151 of the centrifugal fan 16 and the center of the suction port 105 are vertically overlapped. The suction port 105 is located forward of the centrifugal fan 16 in the axial direction F (downward in FIG. 2).

The front panel 110 is provided with a purifier unit (not shown) for purifying the air sucked into the suction port 105. The purifier unit is mounted on the front panel 110 so as to be positioned above the suction port 105.

The front panel 110 is provided with a discharge vane 115 for opening and closing the discharge port 112 and controlling the direction of the air discharged to the discharge port 112 when the discharge port 112 is opened, A discharge vane drive mechanism (not shown) is disposed.

The discharge vane 115 is positioned to rotate in each discharge opening 112, and the discharge vane drive mechanism rotates one discharge vane 115 or a plurality of discharge vanes 115.

The front panel 110 is provided with a grill panel 130 for covering the suction port 105.

The grill panel 130 divides the suction port 105 into a plurality of areas to primarily filter dust and worms that enter the suction port 105.

When the air inside the air conditioner is discharged to the outside through the discharge port 112, the air around the discharge port 112 flows into the discharge port 112 by the pressure difference. Specifically, low-temperature air heat-exchanged through the discharge port 112 is discharged, and hot and humid air around the discharge port 112 flows along the outer surface of the main body 10 having the discharge port 112 formed therein.

Therefore, the peripheral region of the discharge port 112 (the periphery of the discharge port 112 in the main body 10) through which the low-temperature air flows out is cooled. There is a problem that the high temperature and high humidity air flowing in the vicinity of the discharge port 112 is condensed while meeting the area around the discharged discharge port 112. In addition, such dew may fall into the room.

The blocking walls 210 and 220 prevent external air from entering the discharge port 112. That is, the blocking wall restricts the contact between the area around the cooled discharge port 112 and the outside air. The blocking wall may have various shapes that interfere with the air flowing into the discharge port 112 from the vicinity of the discharge port 112.

FIG. 4A is a sectional view of the vicinity of the discharge port 112 of the air conditioner according to the embodiment of the present invention, and FIG. 4B is a plan view of the vicinity of the discharge port 112 of the air conditioner according to the embodiment of the present invention.

4, for example, the blocking wall is disposed on the outer surface of the main body 10 adjacent to the discharge port 112, and is disposed so as to surround at least a partial area of the discharge port 112. As shown in FIG. Hereinafter, the blocking wall disposed on the outer surface of the main body 10 will be referred to as an outer blocking wall 210.

The outer surface blocking wall 210 is disposed on the outer surface of the main body 10 adjacent to the discharge port 112. The outer surface of the main body 10 adjacent to the discharge port 112 means the outer surface of the main body 10 in the direction of the discharge port 112 (the bottom surface of the main body 10). The outer surface of the main body 10 adjacent to the discharge port 112 is spaced at a predetermined distance from the rim of the discharge port 112.

The outer surface blocking wall 210 is disposed apart from the rim of the discharge port 112. At this time, the distance d of the outer surface blocking wall 210 is set differently according to the degree of cooling of the region around the discharge port 112 by the low temperature air A discharged from the discharge port 112.

The outer surface blocking wall 210 is disposed so as to surround at least a part of the discharge port 112. Here, at least a part of the discharge port 112 is disposed so as to surround the discharge port 112, which means that the outer surface blocking wall 210 is located in a part of the periphery of the discharge port 112.

Specifically, the outer surface blocking wall 210 protrudes from the outer surface of the main body 10. Accordingly, the air B flowing into the discharge port 112 is blocked along the outer surface of the main body 10. The height of the outer surface blocking wall 210 is about 1 cm. It is preferable that the outer surface blocking wall 210 is disposed perpendicularly to the outer surface of the main body 10. In the embodiment, the outer surface blocking wall 210 protrudes from the front panel 110 forming the bottom surface of the main body 10.

More specifically, when the discharge port 112 is not formed symmetrically and is formed long in one direction, the outer surface blocking wall 210 is arranged long in the longitudinal direction of the discharge port 112 from the widthwise edge of the discharge port 112 . At this time, the length of the discharge port 112 and the length of the outer surface blocking wall 210 correspond to each other. The outer barrier wall 210 is disposed parallel to the rotation axis of the discharge vane 115. The discharge vane 115 is rotated around the rotation axis to guide discharged air discharged through the discharge port 112 to one side of the discharge port 112 in the width direction. At this time, when the outer surface blocking wall 210 is disposed in parallel with the rotation axis of the discharge vane 115, the outside air flowing into the discharge port 112 can be restricted.

The outer surface blocking walls 210 may be disposed on both sides of the widthwise edge of the discharge port 112, or may be disposed on one side. Preferably, when the air discharged from the discharge port 112 is guided toward one side in the width direction of the discharge port 112, the outer surface blocking wall 210 is disposed on one side in the width direction of the discharge air discharge direction .

5 is a cross-sectional view of the vicinity of the discharge port of another embodiment of the air conditioner according to the present invention.

The blocking wall of another embodiment further includes an inner blocking wall 220, as compared to the embodiment of FIG. Of course, depending on the embodiment, only the inner barrier wall 220 may be included.

Here, the inner blocking wall 220 refers to a blocking wall protruding from the rim of the discharging port 112 to the inside of the discharging port 112.

The inner blocking wall 220 is disposed so as to surround at least a part of the discharge port 112. Specifically, the inner cut-off wall 220 protrudes from the rim of the discharge port 112 to the inside of the discharge port 112. Accordingly, the air flowing into the discharge port 112 along the outer surface of the main body 10 is blocked.

The inner blocking wall 220 is formed to cover at least one region of the discharge port 112. Specifically, when the discharge port 112 is not formed symmetrically and is formed long in one direction, the inner surface blocking wall 220 is arranged long in the longitudinal direction of the discharge port 112 from the widthwise edge of the discharge port 112 . At this time, the length of the discharge port 112 and the length of the inner surface blocking wall 220 correspond to each other. The inner blocking wall 220 is disposed in parallel with the rotation axis of the discharge vane 115.

The inner barrier walls 220 may be disposed on both sides of the widthwise edge of the discharge port 112, or may be disposed on one side. Preferably, when the air discharged from the discharge port 112 is guided so as to face toward one side in the width direction of the discharge port 112, the inner surface blocking wall 220 has a width direction in which the discharge air is discharged, As shown in Fig.

That is, since one side in the width direction of the discharged air toward the discharge air is enlarged by the discharged air to the cooling area around the discharge port 112, the outer surface blocking wall 210 is disposed adjacent to the discharge port 112, The cooling area around the discharge port 112 becomes small, so that the inner surface blocking wall 220 is disposed.

Specifically, the outer surface blocking wall 210B of the embodiment may be arranged long in the longitudinal direction of the discharge port 112 in the widthwise edge of the discharge port 112. [ The outer surface blocking wall 210 is disposed on both sides 210B1 and 210B2 of the widthwise edge of the discharge port 112. [

[ Specifically, the outer blocking wall 210C of the embodiment includes an inner blocking wall 210C2 and an outer blocking wall 210C1.

In the front panel 110, the discharge ports 112 are arranged along the periphery of the suction port 105 from the outside of the suction port 105. The outer blocking wall 210C1 is disposed on the bottom surface of the front panel 110 so as to surround the suction port 105 and the discharge ports 112. [ That is, the outer barrier wall 210C1 forms a closed space at the bottom surface of the front panel 110, and a plurality of discharge ports 112 and an inlet port 105 are disposed therein.

The inner blocking wall 210C2 is disposed on the bottom surface of the front panel 110 so as to surround the suction port 105 to define a boundary between the suction port 105 and the discharge ports 112. [ At this time, the discharge ports 112 are positioned between the inner barrier wall 210C2 and the outer barrier wall 210C1.

Therefore, the air that flows into the discharge port 112 from the outside of the front panel 110 is restricted by the outer cutoff wall 210C1, and the air introduced into the suction port 105 by the inner cutoff wall 210C2 is discharged to the discharge port 112 Is limited.
