  DETAILED DESCRIPTION Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings and wherein like reference numerals refer to like elements throughout. Embodiments for explaining the present disclosure will be described below with reference to these drawings.

  Hereinafter, embodiments of the present disclosure will be described in detail.

  FIG. 1 shows an air conditioner (AC) room interior according to an embodiment of the present disclosure. FIG. 2 shows a lateral cross-sectional view of the AC chamber in FIG. FIG. 3 is an enlarged view of a portion “◯” in FIG. 4 is a cross-sectional plan view taken along line II in FIG. 5 is a cross-sectional plan view taken along line II-II in FIG. Technically speaking, the lateral cross-sectional view of FIG. 2 is a rotational cross-sectional view taken along line III-III of FIG.

  With reference to FIGS. 1 to 5, an AC indoor portion according to an embodiment of the present disclosure will be described.

  The AC indoor part 1 may be installed on the ceiling C. At least a part of the AC room interior 1 may be incorporated in the ceiling C.

  The AC indoor portion 1 may include a housing 10 having an intake port 20 and an exhaust port 21, a heat exchanger 30 disposed inside the housing 10, and a blower fan 40 that circulates air.

  When viewed in the vertical direction, the housing 10 may have a substantially circular shape. The housing 10 may include an upper housing 11, an intermediate housing 12 assembled to the bottom of the upper housing 11, and a bottom housing 13 assembled to the bottom of the intermediate housing 12. At least a part of the upper housing 11 and the intermediate housing 12 may be incorporated in the ceiling C.

  The air inlet 20 for sucking air may be formed in the center of the bottom housing 13, and the air outlet 21 for discharging air may be formed around and outside the air inlet 20. When viewed in the vertical direction, the exhaust port 21 may have a substantially circular shape. Specifically, when viewed from the vertical direction, the exhaust port 21 may include a plurality of arcs separated from each other by the bridge 70d.

  With this structure, the AC chamber 1 may suck air at the bottom, cool or heat the air, and discharge the cooled or heated air from the bottom.

  The bottom housing 13 may have a Coanda curved portion 14 that guides the air exhausted through the exhaust port 21. The Coanda curved portion 14 may be in close contact with the Coanda curved portion 14 and guide the airflow discharged through the exhaust port 21 so as to flow in the Coanda curved portion.

  The grill 15 may be assembled on the bottom of the bottom housing 13 to filter out dust from the air sucked into the inlet 20.

  As shown in FIG. 5, the heat exchanger 30 includes a tube 32 in which a refrigerant circulates, and a header 31 connected to the external refrigerant tube to supply the refrigerant to the tube 32 or collect the refrigerant from the tube 32. May be included. The tube 32 may have a heat exchange pin for expanding the heat radiation area.

  When viewed from the vertical direction, the heat exchanger 30 may have a substantially circular shape. Specifically, the tube 32 of the heat exchanger 30 may have a circular shape. The heat exchanger 30 may be installed on the drain tray 16 such that condensed water generated in the heat exchanger 30 is collected in the drain tray 16.

  The blower fan 40 may be positioned on the inner side in the radial direction of the heat exchanger 30. The blower fan 40 may be a centrifugal fan that sucks air in the axial direction and releases air in the radial direction. The AC indoor unit 1 may include a blower motor 41 that drives the blower fan 40. The blower fan 40 may be referred to as a main fan, and the airflow control fan 60 described later may be referred to as an auxiliary fan.

  With this structure, the AC indoor section 1 may suck indoor air, cool or heat the air, and then release the cooled or heated air again into the room.

  The AC room interior 1 may further include an airflow control device 50 for controlling the discharged airflow.

  The airflow control device 50 may control the direction of the discharged airflow by sucking air around the exhaust port 21 in order to change the pressure. Furthermore, the airflow control device 50 may control the amount of air sucked around the exhaust port 21. In other words, the airflow control device 50 may control the direction of the discharged airflow by controlling the amount of air sucked around the exhaust port 21.

  In this specification, controlling the direction of the discharged airflow is also referred to as controlling the angle of the discharged airflow.

  When the air around the exhaust port 21 is sucked, the airflow control device 50 may suck air from one side in the direction in which the discharged airflow flows.

  Specifically, as shown in FIG. 3, if the direction in which the discharged airflow flows when the airflow control device 50 is not driven is indicated as direction A1, the airflow device 50 is driven in one direction A1. By sucking (S) air from the side, the direction of the airflow discharged so as to flow in the direction A2 may be changed.

  At this time, the direction change angle may be controlled based on the air suction amount. For example, the direction change angle decreases as the air suction amount decreases, and the direction change angle increases as the air suction amount increases.

  The airflow control device 50 may discharge (D) the air sucked to one side in the direction A1 in which the discharged airflow flows. In particular, the airflow control device 50 may discharge air in a direction opposite to the direction in which air is sucked. By doing this, the airflow may be controlled more smoothly by enlarging the airflow discharge angle.

  The airflow control device 50 may suck air from the outside in the radial direction of the exhaust port 21 (or from above the discharged airflow). Thus, since the airflow control device 50 sucks air from the outside of the exhaust port 21 in the radial direction, the discharged airflow spreads widely from the central portion in the radial direction of the exhaust port 21 toward the outside in the radial direction. It may spread.

  The airflow control device 50 includes an airflow control fan 60 for generating a suction force for sucking air around the exhaust port 21, an airflow control motor 61 for driving the airflow control fan 60, and air sucked by the airflow control fan 60. May be included.

  The airflow control fan 60 may be accommodated in the fan case 62. In the present embodiment, three airflow control fans 60 each formed at 120 degrees may be provided. The airflow control fans 60 are not limited to this, and more airflow control fans 60 may be designed in various arrangements, or fewer airflow control fans 60 may be designed.

  In the present embodiment, the airflow control fan 60 corresponds to a centrifugal fan, but is not limited to this, and the airflow control fan 60 includes various fans such as an axial flow fan, a cross flow fan, and a mixed flow fan. May be used.

  The guide path 70 connects the inflow hole 71 that sucks air around the exhaust port 21 to the discharge hole 72 that discharges the sucked air. When the passage connecting the intake port 20 to the exhaust port 21 is called a main path, the guide path 70 may be said to be formed by branching from the main path.

  The inflow hole 71 may be formed on the Coanda curved portion 14 of the bottom housing 13. Therefore, the discharged airflow bent toward the inflow hole 71 of the bottom housing 13 according to the suction force of the airflow control fan 60 may flow over the surface of the Coanda curved portion 14.

  The inflow hole 71 may be formed by a plurality of arc-shaped slits. The plurality of slits may be arranged in the circumferential direction so as to be separated from each other at a predetermined interval.

  The discharge hole 72 may be positioned around the exhaust port 21 on the opposite side of the inflow hole 71. Specifically, the discharge hole 72 may be formed in the fan case 62.

  As described above, the airflow control device 50 may discharge (D) air to one side in the direction A1 in which the discharged airflow flows by this structure. In particular, the airflow control device 50 may control the airflow more smoothly by expanding the airflow discharge angle by discharging air in the direction opposite to the suction direction.

  The guide path 70 is formed on the outer side of the housing 10 in the circumferential direction. The first path 70 a is poured into the inflow hole 71, the second path 70 b extends radially inward from the first path 70 a, and the fan case 62. The formed third passage 70c may be included. The second passage 70b may be formed in the bridge 70d that crosses the exhaust port 21.

  Therefore, the air sucked through the inflow hole 71 may be discharged from the discharge hole 72 through the first passage 70a, the second passage 70b, and the third passage 70c.

  However, the structure of the guide path 70 is merely an example, and the structure, shape, and arrangement of the guide path 70 are not limited as long as the guide path 70 connects the inflow hole 71 and the discharge hole 72.

  With this structure, the AC chamber according to the embodiment of the present disclosure has a blade structure as compared to a conventional AC chamber in which the blade is disposed in the exhaust port and the airflow is controlled by rotating the blade. The discharged airflow may be controlled without any problem. Therefore, since there is no interference by the blade, the discharge amount may be increased and the circulating noise may be reduced.

  Further, in contrast to a conventional AC room interior that has an exhaust port that must be formed in a linear shape to rotate the blade, the AC room interior according to embodiments of the present disclosure may be formed in a circular shape. It has a good exhaust port, so the housing and heat exchanger may be formed in a circular shape, and the appearance aesthetics may be improved by different designs. Further, considering that the shape of a typical blower fan is circular, in the embodiment of the present disclosure, air flows more naturally and pressure loss is reduced, and as a result, AC cooling performance or heating performance is reduced. It may be improved.

  FIG. 6 is a block diagram of an AC control system according to an embodiment of the present disclosure.

  The AC includes a controller 92 that controls a general operation, an input unit 90 that receives an operation command, an outdoor temperature sensor 91a that detects an outdoor temperature, an indoor temperature sensor 91b that detects an indoor temperature, and an evaporator temperature. An evaporator temperature sensor 91c to detect, an indicator section 93 that shows various information to the outside, a compressor driver 94 that drives the compressor 95, an electric expansion valve 96, a blower fan driver 97 that drives the blower fan 40, and airflow An airflow control fan driver 98 that drives the control fan 60 may be included.

  The controller 92 may receive various operation commands and / or temperature information from the input unit 90, the outside temperature sensor 91a, the indoor temperature sensor 91b, and the evaporator temperature sensor 91c. Based on this, the control command may be transmitted to the indicator unit 93, the compressor driver 94, the electronic expansion valve 96, the blower fan driver 97, and the airflow control fan driver 98.

  The airflow control fan driver 98 may control whether or not to drive the airflow control motor 61 in accordance with a control command from the controller 92 to control the driving speed. By doing in this way, you may control the quantity of the air attracted | sucked around the exhaust port 21, and the direction of the discharged | emitted airflow.

  In the embodiment, the airflow control device 250 may discharge the air sucked from the periphery of the exhaust port 21 toward the upper region of the heat exchanger 30 according to the direction in which the airflow flows. The discharged air is cooled or heated by the heat exchanger 30 and is finally discharged into the room through the exhaust port 21.

  An inflow hole 271 for sucking air around the exhaust port 21 to release air into the housing 10 is formed in the bottom housing 13, and an exhaust hole 272 for discharging the sucked air is formed in the housing 10. .

  The guide path 270 is formed so as to connect the inflow hole 217 and the discharge hole 272. The guide passage 270 is formed in the circumferential direction, and includes a first passage 270a poured into the inflow hole 271; a second passage 270b extending radially inward from the first passage 270a; and a third passage formed in the fan case 62. A passage 270c and a fourth passage 270d extending from the third passage 270c to the inside of the housing 10 and pouring into the discharge hole 272 may be included.

  Accordingly, the air sucked through the inflow hole 271 may be discharged from the discharge hole 272 through the first passage 270a, the second passage 270b, the third passage 270c, and the fourth passage 270d.

  However, the structure of the guide path 270 is merely an example, and as long as the guide path 270 connects the inflow hole 271 and the discharge hole 272, the structure, shape, and arrangement of the guide path 270 are not limited.

  With reference to FIG. 20, an AC room interior according to an embodiment of the present disclosure will be described. The same features as those of the above-described embodiment are denoted by the same reference numerals, and redundant description is omitted here.

  Unlike the above-described embodiment, the airflow control device 450 may control the direction of the discharged airflow by blowing air around the exhaust port 21 in order to change the pressure. Specifically, unlike the above-described embodiment in which the airflow control device generates a negative pressure around the exhaust port 21 to control the direction of the discharged airflow, the airflow control device 450 according to this embodiment The direction of the discharged air flow may be controlled by generating a positive pressure around the exhaust port 21.

  The airflow control device 450 may control the amount of air blown around the exhaust port 21. In other words, the airflow control device 450 may control the direction of the discharged airflow by controlling the amount of air blown around the exhaust port 21.

  Here, controlling the direction of the discharged airflow means controlling the discharge angle of the airflow. In other words, it means controlling whether the discharged airflows are merged or broadened.

  When the air around the exhaust port 21 is blown, the airflow control device 450 may blow air from one side in the direction in which the discharged airflow flows.

  Specifically, as shown in FIG. 20, considering that the direction in which the airflow discharged when the airflow control device 450 is not driven is indicated as the direction A1, the airflow control device 450 uses the air during driving. By blowing (B) to one side of the direction A1, the direction in which the discharged airflow flows may be changed to the direction A2.

  The airflow control device 450 may blow air from the inside in the radial direction of the exhaust port 21 (or from below the discharged airflow). That is, when the airflow control device 450 is not driven, the discharged airflows may be relatively merged, and when the airflow control device 450 is driven, the discharged airflow may be spread relatively widely outward in the radial direction.

  The airflow control device 450 guides the air flowing by the airflow control fan 460, the airflow control motor 461 that drives the airflow control fan 460, and the airflow control fan 460 that generates the blowing force that blows the air around the exhaust port 21. A guide path 470 may be included.

  The guide path 470 connects a duct 472 that blows air around the exhaust port 21 to an inflow hole 471 that sucks air.

  FIG. 21 is a cross-sectional view illustrating main parts of the AC indoor portion according to the embodiment of the present disclosure in comparison with FIG. 20.

  With reference to FIG. 21, an AC room interior according to an embodiment of the present disclosure will be described. The same features as those of the above-described embodiment are denoted by the same reference numerals, and redundant description is omitted here.

  Similar to the above embodiment, the airflow control device 550 may control the direction of the discharged airflow by blowing air around the exhaust port 21 in order to change the pressure. However, unlike the above embodiments, the airflow control device 550 may blow air from the outside in the radial direction of the exhaust port 21 (or from above the discharged airflow).

  That is, when the airflow control device 550 is not driven, the discharged airflow may be spread relatively widely, and when the airflow control device 550 is driven, the discharged airflow may be relatively merged radially inward.

  The airflow control device 550 includes an airflow control fan 560 that generates a blowing force for blowing air around the exhaust port 21, an airflow control motor 561 that drives the airflow control fan 560, and an airflow blown by the airflow control fan 560.

  FIG. 22 is a cross-sectional view illustrating main parts of the AC indoor portion according to the embodiment of the present disclosure in comparison with FIG. 20.

  With reference to FIG. 22, an AC room interior according to an embodiment of the present disclosure will be described. The same features as those of the above-described embodiment are denoted by the same reference numerals, and redundant description is omitted here.

  The airflow control device 650 may control the direction of the discharged airflow by blowing air around the exhaust port 21 in order to change the pressure. However, unlike the embodiment of FIGS. 20 and 21 in which the airflow control device controls the discharged airflow by pressing the discharged airflow, the airflow control device 650 draws the discharged airflow. Thus, the discharged airflow may be controlled.

  For this purpose, the Coanda curved portion 614 may be formed around the exhaust port 21, and the airflow control device 650 may discharge the auxiliary airflow X in the tangential direction of the Coanda curved portion 614.

  The Coanda curved portion 614 may guide the auxiliary airflow X discharged through the discharge hole 672 so as to be in close contact with the surface of the Coanda curved portion 614 and to flow over the surface of the Coanda curved portion 614 due to the Coanda effect. . The Coanda curved portion 614 may be integrally formed with the housing 10, for example, the bottom housing 13.

  The Coanda curved portion 614 may have a shape that is substantially convex toward the exhaust port 21. Therefore, the speed of the auxiliary airflow X flowing over the Coanda curved portion 614 may increase and the pressure may decrease. Therefore, the main airflow discharged from the exhaust port 21 is drawn toward the auxiliary airflow X in order to change the direction from A1 to A2.

  The direction of the auxiliary airflow X discharged through the discharge hole 672 may be a tangential direction of the Coanda curved portion 614 while substantially corresponding to the direction of the main airflow.

  The guide path 670 for guiding the auxiliary airflow X connects the inflow hole 671 for sucking air to the discharge hole 672 for discharging sucked air. When a passage connecting the intake port 20 and the exhaust port 21 is called a main path, the guide path 670 may be said to be formed by branching from the main path.

  The discharge port 672 is formed in the vicinity of the Coanda curved portion 614 so that the auxiliary airflow X is discharged in the tangential direction of the Coanda curved portion 614. Specifically, the discharge hole 672 may be formed between the inner peripheral surface 22 of the exhaust port 21 and the Coanda curved portion 614.

  The airflow control device 650 may blow the auxiliary air X from the outside in the radial direction of the exhaust port 21 (from above the main airflow). That is, when the airflow control device 650 is not driven, the main exhaust airflow may be relatively merged, and when the airflow control device 650 is driven, the main exhaust airflow may be spread relatively widely.

  The airflow control device 650 may include an airflow control fan 660 that blows air to generate the auxiliary airflow X, and an airflow control motor 661 that drives the airflow control fan 660. The airflow control fan 660 is disposed separately from the main blower fan 40, and a plurality of airflow control fans may be provided as necessary.

  In order to increase the force of the auxiliary airflow X drawn in the main airflow, the airflow control device 650 may increase the speed of the auxiliary airflow X. In other words, as the speed of the auxiliary airflow X increases, the pressure drop increases, and the force that draws the main flow may be increased. The speed of the auxiliary airflow X may be higher than at least the speed of the airflow.

  The inflow hole 671 of the guide path 670 may be formed around the exhaust port 21. Therefore, the airflow control device 650 may generate the auxiliary airflow X by sucking the air around the exhaust port 21.

  FIG. 23 is a cross-sectional view showing main parts of the AC indoor portion according to the embodiment of the present disclosure in comparison with FIG. 20.

  With reference to FIG. 23, an AC indoor portion according to an embodiment of the present disclosure will be described. The same features as those of the above-described embodiment are denoted by the same reference numerals, and redundant description is omitted here.

  Similar to the airflow control device 650 of FIG. 22, the airflow control device 750 of the present embodiment controls the discharged airflow by blowing air around the exhaust port 21 in order to draw the discharged airflow. Also good.

  However, unlike the airflow control device 650, the airflow control device 750 may blow the auxiliary airflow X from the inside in the radial direction of the exhaust port 21 (or from below the main airflow). That is, when the airflow control device 750 is not driven, the main exhaust airflow spreads relatively widely, and when the airflow control device 750 is driven, the main exhaust airflow relatively merges.

  The Coanda curved portion 714 may be formed around the exhaust port 21, and the airflow control device 750 may discharge the auxiliary airflow X in the tangential direction of the Coanda curved portion 714.

  The Coanda curved portion 714 guides the auxiliary airflow X discharged through the discharge hole 772 so as to be in close contact with the surface of the Coanda curved portion 714 and to flow over the surface of the Coanda curved portion 714 due to the Coanda effect. Also good.

  The Coanda curved portion 714 may have a shape that is substantially convex toward the exhaust port 21. Therefore, the speed of the auxiliary airflow X flowing over the Coanda curved portion 714 may be increased and the pressure may be decreased. Therefore, the main airflow discharged from the exhaust port 21 is drawn toward the auxiliary airflow X in order to change the direction from A1 to A2.

  The direction of the auxiliary airflow X discharged through the discharge hole 772 may be the tangential direction of the Coanda curved portion 714 while substantially corresponding to the direction of the main airflow.

  The guide path 770 for guiding the auxiliary airflow X connects the inflow hole 771 for sucking air to the discharge hole 772 for discharging the sucked air.

  Similar to the air flow control device 650 of FIG. 22, the air flow control device 850 of this embodiment controls the discharged air flow by blowing air around the exhaust port 21 in order to draw the discharged air flow. May be.

  However, unlike the airflow control device 650 of FIG. 22, the airflow control device 850 generates the auxiliary airflow X by sucking air from the inside of the housing 10 without sucking air from around the exhaust port 21. May be.

  Specifically, a part of the air cooled by the heat exchanger 30 may be discharged from the discharge hole 872 through the guide passage 870 to generate the auxiliary airflow X, and the remaining part of the air is the main airflow. May be discharged from the exhaust port 21 to generate

  The Coanda curved portion 814 may be formed around the exhaust port 21, and the airflow control device 850 may discharge the auxiliary airflow X in the tangential direction of the Coanda curved portion 814.

  The airflow control device 850 may further include an airflow control fan 860 that blows air to generate the auxiliary airflow X, and an airflow control motor 861 that drives the airflow control fan 860.

  FIG. 25 is a cross-sectional view illustrating main parts of the AC indoor portion according to the embodiment of the present disclosure in comparison with FIG. 21.

  With reference to FIG. 25, an AC room interior according to an embodiment of the present disclosure will be described. The same features as those of the above-described embodiment are denoted by the same reference numerals, and redundant description is omitted here.

  Similarly to the airflow control device 750 of FIG. 23, the airflow control device 950 according to the present embodiment controls the discharged airflow by blowing air around the discharge port 21 in order to draw the discharged airflow. May be.

  However, unlike the airflow control device 750 of FIG. 23, the airflow control device 950 generates the auxiliary airflow X by sucking air from the inside of the housing 10 without sucking air from the periphery of the exhaust port 21. May be.

  Specifically, a portion of the air in the upper region of the heat exchanger 30 may be exhausted from the exhaust hole 972 through the guide channel 970 to generate the auxiliary airflow X, while the remaining portion of the air is the main airflow May be discharged from the exhaust port 21 to generate

  The Coanda curved portion 914 may be formed around the exhaust port 21, and the airflow control device 950 may discharge the auxiliary airflow X in the tangential direction of the Coanda curved portion 914.

  The guide path 970 that guides the auxiliary airflow X connects the inflow hole 971 that sucks air to the discharge hole 972 that discharges the sucked air.

  The airflow control device 950 may further include an airflow control fan 960 that blows air to generate the auxiliary airflow X, and an airflow control motor 961 that drives the airflow control fan 960.

  FIG. 26 is a perspective view of an AC according to an embodiment of the present disclosure. FIG. 27 is a bottom view of the AC shown in FIG. FIG. 28 is a developed view of the AC shown in FIG. FIG. 29 is a lateral cross-sectional view taken along line II identified in FIG.

  Hereinafter, the AC 1001 according to an embodiment of the present disclosure will be described with reference to FIGS.

  The AC 1001 may be installed on the ceiling C. At least a part of the AC 1001 may be built in the ceiling C.

  The AC 1001 may include a housing 1010 having an intake port 1020 and an exhaust port 1021, a heat exchanger 1030 disposed in the housing 1010, and a blower fan 1040 that circulates air.

  When viewed from the vertical direction, the housing 1010 may have a substantially circular shape. The housing 1010 may include an upper housing 1011 disposed in the ceiling C, an intermediate housing 1012 assembled to the bottom of the upper housing 1011, and a bottom housing 1013 assembled to the bottom of the intermediate housing 1012.

  The air inlet 1020 for sucking air may be formed at the center of the bottom housing 1013, and the air outlet 1021 for discharging air may be formed around and outside the air inlet 1020. When viewed from the vertical direction, the exhaust port 1021 may have a substantially circular shape.

  With this structure, the AC 1001 may suck air at the bottom, cool or heat the air, and discharge the cooled or heated air from the bottom again.

  The bottom housing 1013 may have a first guide surface 1014a and a second guide surface 1014b, which form an exhaust port 1021. The first guide surface 1014a may be disposed near the intake port 1020, and the second guide surface 1014b may be disposed further away from the intake port 1020 than the first guide surface 1014a. The first and / or second guide surfaces 1014a and 1014b may include a Coanda curved portion that guides the air discharged through the exhaust port 1021. The Coanda curved portion may guide the air discharged through the exhaust port 1021 so as to be in close contact with the Coanda curved portion and flow over the Coanda curved portion.

  The grill 1015 may be assembled on the bottom of the bottom housing 1013 to filter out dust from the air drawn into the air inlet 1020.

  The heat exchanger 1030 may be mounted in the housing and positioned in an air passage between the air inlet 1020 and the air outlet 1021. The heat exchanger 1030 includes a tube (not shown) through which the refrigerant circulates and a header (not shown) connected to the external refrigerant tube to supply the refrigerant to the tube and collect the refrigerant from the tube. May be included. The tube may have a heat exchange pin for expanding the heat radiation area.

  When viewed from the vertical direction, the heat exchanger 1030 may have a substantially circular shape. The heat exchanger 1030 may be installed on the drain tray 1016 such that condensed water generated in the heat exchanger 1030 is collected in the drain tray 1016.

  The blower fan 1040 may be positioned on the radially inner side of the heat exchanger 1030. The blower fan 1040 may be a centrifugal fan that sucks air in the axial direction and releases air in the radial direction. AC 1001 may include a blower motor 1041 that drives a blower fan 1040.

  With this structure, the AC 1001 may suck indoor air, cool or heat the air, and release the cooled or heated air again into the room.

  AC 1001 may further include a heat exchange pipe 1081 connected to heat exchanger 1030 through which refrigerant flows, and a drain pump 1082 that releases condensed matter collected in drain tray 1016. The heat exchange pipe 1081 and the drain pump 1082 may be positioned above the bridge 1100 described later without blocking the intake port. Specifically, the heat exchange pipe 1081 may be securely received within a safety heat exchange pipe receiving portion 1016a disposed on the drain tray 1016, and the drain pump 1082 is a safety disposed on the drain tray 1016. It may be safely received within the drain pump receiving portion 1016b (see FIG. 33).

  Referring to FIG. 27, the AC 1001 may further include a bridge 1100 that is positioned adjacent to the exhaust port 1021 and extends in the circumferential direction of the exhaust port 1021 as much as a predetermined length. The bridges 1100 may be spaced apart at predetermined intervals along the circumferential direction, and the number thereof may be three. The bridge 1100 may be arranged to connect the first guide surface 1014a and the second guide surface 1014B.

  When air is released from the ring-shaped exhaust port 1021 in all directions, a relatively high pressure is generated around the exhaust port 1021 and a relatively low pressure is generated around the intake port 1020. Further, since air discharged from all directions of the exhaust port 1021 forms an air curtain, air that should be sucked through the intake port 1020 may not be supplied to the intake port 1020 side. Under such circumstances, the air exhausted from the exhaust port 1021 is sucked again through the air intake port 1020, causing condensation inside the housing 1010 and loss of the exhausted air, which is an effective performance felt by the user. Will be reduced.

  The bridge 1100 according to an embodiment of the present disclosure is positioned on the exhaust port 1021 to block the exhaust port 1021 as much as a predetermined length. Therefore, the exhaust port 1021 may be partitioned into a first section S1 in which air is released and a second section S2 in which air is not substantially released due to blocking by the bridge 1100. That is, the bridge 1100 may form the second section so as to supply air sucked through the air inlet 1020. Further, the bridge 1100 may promote a smooth supply of air to the inlet 1020 by reducing the difference between the low pressure around the inlet 1020 and the high pressure around the outlet 1021. .

  The bridge 1100 may include a pair of discharge guide surfaces 1101 that are closer together so as to be positioned closer to the direction in which the air is released so as to minimize the second section S2 formed by the bridge 1100. The air discharged from the exhaust port 1021 by the discharge guide surface 1101 may spread from the exhaust port 1021 because of the discharge guide surface 1101.

  In FIG. 27, AC 1001 is shown to have three equidistant bridges 1100, ie, three bridges separated by 120 °, but is not limited thereto, and as shown in FIG. Only a single bridge 1100a may be provided. Alternatively, as shown in FIG. 31, two bridges 1100b separated by 180 ° may be provided, or as shown in FIG. 32, four bridges 1100c separated by 90 ° may be provided. The plurality of bridges 1100, 1100 b, and 1100 c may be disposed along the circumferential direction of the exhaust port 1021 at different angles. Alternatively, although not shown, five or more bridges may be arranged. That is, there is no limit on the number of bridges.

  However, in order to form the second section S2 and promote a smooth supply of air sucked through the intake port 1020, the total length of the bridges 1100, 1100a, 1100b, 1100c is the total length of the exhaust port. It may be set to 5% or more and 40% or less. In other words, the ratio of the length of the second section S2 to the total length of the first section S1 and the second section S2 may be set to 5% or more and 40% or less.

  Further, when a plurality of bridges 1100, 1100b, and 1100c are arranged, the display units 1120, 1120b, and 1120c may be arranged on one bottom portion of the bridges 1100, 1100b, and 1100c.

  The air discharged from the exhaust port 1021 by the bridges 1100, 1100a, 1100b, and 1100c may not be sucked into the intake port 1020 again and may spread to cool or heat the room.

  Referring to FIG. 33, the AC may further include a discharge guide rib 1110 disposed in the exhaust port 1021a and extending vertically along a direction in which air is discharged. Specifically, the discharge guide rib 1110 may be formed on the drain tray 1016. The drain tray 1016 may include a drain tray exhaust port 1021a corresponding to the exhaust port 1021 of the housing 1010, and the discharge guide ribs 1110 are disposed in the drain tray exhaust port 1021a in order to reduce the area of the drain tray exhaust port 1021a. By arranging, the flow velocity of the air discharged through the drain tray exhaust port 1021a may be increased. The discharge guide rib 1110 may guide the discharged air so that the air discharged from the exhaust port 1021a may be expanded while being discharged. The discharge guide rib 1110 may be disposed so as to correspond to the first section S1 of the exhaust port 1021 where the bridge 1100 is not formed.

  Further, the discharge guide ribs 1110 may be disposed on the drain tray exhaust port 1021a in order to reinforce the rigidity of the housing 1010.

  The discharge guide ribs 1110 may include a first discharge guide rib 1111 extending along the circumferential direction of the drain tray exhaust port 1021a and a second discharge guide rib 1112 extending along the radial direction of the drain tray exhaust port 1021a.

  The area of the drain tray exhaust port 1021a is composed of a first discharge guide rib 1111 formed along the circumferential direction of the drain tray exhaust port 1021a and a second discharge guide rib 1112 formed along the radial direction of the drain exhaust port 1021a. May be increased to increase the flow rate of the air passing through the drain tray exhaust port 1021. A plurality of second discharge guide ribs 1112 may be formed.

  34 and 35 show a part of the wide discharge guide rib 1110 shown in FIG.

  Referring to FIG. 34, the second discharge guide rib 1112a may be inclined downward toward the bridge 1100 as it is positioned closer to the bridge 1100 when viewed from the radial direction of the drain tray exhaust port 1021a. Specifically, the second discharge guide rib 1112a may be assembled to the first discharge guide rib 1111a such that the second discharge guide rib 1112a is inclined in the direction in which the discharged air spreads as it approaches one of the ends from the center. Therefore, the second discharge guide rib 1112a may minimize the second section S2 by expanding the air discharged from the drain tray exhaust port 1021a toward the bridge 1100. That is, if possible, air may be discharged in all directions of the AC 1011.

  Referring to FIG. 35, the second discharge guide rib 1112b may be inclined downwardly away from the bridge 1100 as it is positioned closer to the bridge 1100 when viewed from the radial direction of the drain tray exhaust port 1021a. Specifically, the second discharge guide ribs 1112b are arranged so that the second discharge guide ribs 1112b are inclined in the direction in which the discharged air merges as the second discharge guide ribs 1112b approach one of the ends from the center. It may be assembled to the discharge guide rib 1111b. Accordingly, the second discharge guide rib 1112b may form a powerful air flow by collecting the air discharged from the drain tray exhaust port 1021a.

  Referring to FIG. 36, the housing 1010 may include only the second discharge guide rib 1112c without the first discharge guide rib 1111.

  Further, although not shown, the first discharge guide rib 1111 may be disposed to be inclined so as to be separated from the intake port 1020 in the radial direction of the drain tray exhaust port 1021a, and discharged from the drain tray exhaust port 1021a. The air to be discharged may spread from the intake port 1020 in the radial direction of the drain tray exhaust port 1021a.

  As shown in FIG. 38, the intermediate housing 1012 may include an intermediate housing exhaust port 1021b corresponding to the exhaust port 1021 of the bottom housing 1013 and the drain tray exhaust port 1021a of the drain tray 1016. A housing discharge guide rib 1113 corresponding to the second discharge guide rib 1112 of the tray 1016 may be provided. The housing discharge guide rib 1113 may be disposed on the same plane as the second discharge guide rib 1112, or may be assembled to the second discharge guide rib 1112.

  FIG. 37 is an enlarged view of a portion “◯” specified in FIG. 29. FIG. 38 is an exploded view of the intermediate housing and the bottom housing as shown in FIG. FIG. 39 shows air circulation by the airflow control device of Ac shown in FIG.

  Referring to FIGS. 37 to 39, the AC 1001 may further include an airflow control device 1050 that controls the airflow.

  The airflow control device 1050 may control the direction of the discharged airflow by sucking air around the exhaust port 1021 in order to change the pressure. Further, the airflow control device 1050 may control the air suction amount around the exhaust port 1021. In other words, the airflow control device 1050 may control the direction of the discharged airflow by controlling the air suction amount around the exhaust port 1021.

  Here, controlling the direction of the discharged airflow means controlling the angle of the discharged airflow.

  When the air around the exhaust port 1021 is sucked, the airflow control device 1050 may suck air from one side in the direction in which the discharged airflow flows.

  Specifically, as shown in FIG. 37, when the airflow control device 1050 is not driven, considering that the direction in which the discharged airflow flows is indicated as the direction A1, the airflow control device 1050 is viewed from one side of the direction A1. By sucking air, it may be driven to change the direction of flow of the discharged airflow to the direction A2.

  At this time, the direction change angle may be controlled based on the air suction amount. For example, the smaller the air suction amount, the smaller the direction change angle, and the larger the air suction amount, the larger the direction change angle.

  The airflow control device 1050 may suck air from the outside of the exhaust port 1021 in the radial direction. Thus, since the airflow control device 1050 sucks air from the outside of the exhaust port 1021 in the radial direction, the discharged airflow may spread widely from the center in the radial direction of the exhaust port 1021 to the outside in the radial direction.

  The airflow control device 1050 includes an airflow control fan 1060 that generates a suction force for sucking air around the exhaust port 1021, an airflow control motor 1061 that drives the airflow control fan 1060, and air sucked by the airflow control fan 1060. And a guide path 1070 for guiding the vehicle.

  The airflow control fan 1060 may be assembled in a fan case 1062 disposed at the end of the bridge 1100 adjacent to the air inlet 1020. In the present embodiment, three air flow control fans 1060 are provided corresponding to the number of bridges, but the number of air flow control fans 1060 is not limited to this, and the number and arrangement of air flow control fans 1060 are bridges. As with the number and arrangement of 1100, it may be designed in various ways.

  The airflow control fan 1060 corresponds to a centrifugal fan in the embodiment related to FIG. 37, but is not limited thereto, and various other fans such as an axial fan, a crossflow fan, a mixed fan, and the like can control the airflow. It may be used for fan 1060.

  The guide portion 1070 connects the inflow hole 1071 that sucks air around the exhaust port 1021 to the discharge hole 1072 that discharges the sucked air. A part of the guide path 1070 may be formed on the bridge 1100.

  The inflow hole 1071 may be formed on the second guide surface 1041b of the bottom housing 1013. The discharge hole 1072 may be formed adjacent to the exhaust port 1021 on the opposite side of the inflow hole 1071. Specifically, the discharge hole 1072 may be formed in the fan case 1062 disposed on the bottom of the bridge 1100.

  As described above, this structure allows the airflow control device 1050 to discharge air sucked in the direction opposite to the direction A1 in which the discharged airflow flows, and widens the discharge angle of the airflow, thereby smoothing the airflow. May be controlled.

  Referring to FIGS. 37 and 38, the guide path 1070 is formed in the circumferential direction outside the housing 1010, and a first path 1070a poured into the inflow hole 1071 and a second path 1070b extending radially inward from the first path 1070a. And a third passage 1070 c formed inside the fan case 1062. The second passage 1070 b may be formed on the bridge 1100.

  Accordingly, the air sucked through the inflow hole 1071 may be discharged from the discharge hole 1072 through the first passage 1070a, the second passage 1070b, and the third passage 1070c.

  However, the structure of the guide path 1070 is merely an example, and as long as the guide path 1070 connects the inflow hole 1071 and the discharge hole 1072, the structure, shape, and arrangement of the guide path 1070 are not limited.

  Referring to FIGS. 37 and 39, the discharge hole 1072 may be formed to discharge air toward the bottom surface 1103 of the bridge 1100. The discharge hole 1072 may be formed below the bridge 1100.

  If the air flowing in through the inflow hole 1071 is cooling air, condensation is caused by the temperature difference between the inside through which the cooling air passes and the outside of the bridge 1100 while the cooling air passes through the bridge 1100. It may occur on the outside of 1100, that is, on the bottom surface 1103 of the bridge 1100.

  On the other hand, in the case of the AC 1001 according to an embodiment of the present disclosure, the cooling air sucked through the inflow hole 1071 is discharged to the bottom surface 1103 of the bridge 1100 through the discharge hole 1072 formed below the bridge 1100. The temperature difference between the inside and the outside may be reduced. Thereby, condensation may be prevented.

  Referring to FIGS. 27 and 40, the AC 1001 may further include a display unit 1120 below one of the plurality of bridges 1100.

  Display unit 1120 may display the status of the operation of AC 1001 to the user. Specifically, the display unit 1120 displays whether the AC 1001 is operating, the direction of the discharged airflow, whether the AC 1001 is currently driven in a cooling mode or a heating mode, However, the present invention is not limited to this.

  The display unit 1120 may include a discharge guide surface 1122 having substantially the same shape as the discharge guide surface 1101 of the bridge 1100. Therefore, even the air discharged from the discharge hole 1021 adjacent to the place where the display unit 1120 is disposed may be expanded while being discharged from the exhaust port 1021.

  Although not shown, in addition to the display unit 1120, a remote control receiver (not shown), an input unit (not shown) of the AC 1001, and a communication unit (not shown) that enables communication with an external device. One of them may also be positioned below the bridge 1100.

  When the display unit 1120 is disposed below the bridge 1100, the discharge hole 1072 cannot discharge air toward the bottom surface 1103 of the bridge 1100. Accordingly, an insulating material may be disposed between the display unit 1120 and the bridge 1100 in order to prevent the problem of condensation that may occur on the display unit 1120 side.

  Referring to FIGS. 39 and 41, the discharge hole 1072 may further include a discharge hole rib 1073 extending in a direction in which air is discharged from the discharge hole 1072. In other words, the discharge hole rib 1073 may be formed by extending in the radial direction of the exhaust port 1021. The discharge hole rib 1073 may extend horizontally and / or vertically. One discharge hole rib 1073 extending in the vertical direction and four discharge hole ribs 1073 extending in the horizontal direction are provided, but the number of discharge hole ribs 1073 is not limited.

  The discharge hole rib 1073 is arranged so that the air discharged from the discharge hole 1072 is discharged from the discharge hole 1072 so as to be discharged in substantially the same direction as the airflow discharged from the exhaust port 1021 after contacting the bottom surface 1103 of the bridge 1100. Guide the exhausted air.

  Furthermore, when the airflow control device 1050 is driven, that is, when a part of the air discharged from the exhaust port 1021 is not sucked through the inflow hole 10171, a part of the air discharged from the exhaust port 1021 flows into the exhaust hole 1072. You may be prevented from doing it.

  FIG. 42 shows an embodiment of the discharge hole of FIG. 41 viewed from the radial direction of the exhaust port. FIG. 43 shows an embodiment of the exhaust hole of FIG. 41 as viewed from the radial direction of the exhaust port. FIG. 44 is a perspective view of an embodiment of the discharge hole of FIG.

  Referring to FIG. 43, the discharge hole rib 1073b of the discharge hole 1072 may extend only in the horizontal direction.

  Referring to FIG. 44, the discharge hole rib 1073c of the discharge hole 1072 extends in the vertical direction, but is inclined at a predetermined angle with respect to the direction in which the air is discharged so that the air discharged from the discharge hole 1072 may spread. It may be arranged to do.

  Referring to FIG. 45, the discharge hole rib 1073d of the discharge hole 1072 extends in the horizontal direction, but the air discharged from the discharge hole 1072 may have a slope substantially the same as the bottom surface 1103 of the bridge 1100. In the direction in which air is discharged from the discharge hole 1072, it may be arranged to be inclined downward. Accordingly, the air discharged from the discharge hole 1072 may be smoothly released across the bottom surface 1103 of the bridge 1100, thereby reducing air loss caused by the collision with the bottom surface 103 of the bridge 1100.

  46 is a bottom view of an AC without the grill shown in FIG. FIG. 47 is a view of a portion “A” specified in FIG. 46 as viewed obliquely from below. FIG. 48 is a view of a portion “B” specified in FIG. 46 as viewed obliquely from below. FIG. 49 is one embodiment of the bottom housing of FIG. 50 is one embodiment of the bottom housing of FIG.

  46 and 47, the air flow control fan 1060 of the AC 1001 may be disposed below the bridge 1100, and the air sucked from the inlet hole 1071 to the outside of the outlet 1021 in the radial direction through the outlet hole 1072. May be discharged. The discharge hole 1072 may be positioned on the opposite side of the exhaust port 1021 where the inflow hole 1071 is formed.

  46 and 48, when the display unit 1120 is disposed below the bridge 1100, the airflow control fan 1060a is disposed at an end portion near the air inlet 1020 of the bridge 1110 positioned above the display unit 1120. The display unit 1120 is positioned inside the exhaust port 1021 in the radial direction.

  The discharge hole 1072a through which air is discharged from the airflow control fan 1060a may be positioned on the first guide surface 1014a on the left side of the display unit 1120. Specifically, unlike the fan case 1062 disposed adjacent to the bridge 1100 that does not have the display unit 1120 below, the fan case 1062a containing the airflow control fan 1060a has air discharged from the airflow control fan 1060a. The expansion duct 1064a arranged to connect the opening 1063a positioned on the left side with respect to the display unit 1120 and the opening 1063a of the airflow control fan 1060a to the discharge hole 1072a formed on the first guide surface 1014a. You may have. Accordingly, the air sucked through the inflow hole 1071 may be discharged through the discharge hole 1072a formed on the left side of the display unit 1120 without interfering with the display unit 1120.

  On the other hand, as shown in FIG. 49, the discharge hole 1072 b may be formed on the right side with respect to the display unit 1120. In this case, the fan case 1062b containing the airflow control fan 1060b has a first opening 1063b through which air is discharged from the airflow control fan 1060b formed on the right side of the display unit 1120 and an opening 1063b of the airflow control fan 1060b. You may have the expansion duct 1064b arrange | positioned so that it may connect with the discharge hole 1072b formed on the guide surface 1014a. Accordingly, the air sucked through the inflow hole 1071 may be discharged through the discharge hole 1072b formed on the right side of the display unit 1120 without interfering with the display unit 1120.

  Alternatively, as shown in FIG. 50, a discharge hole (not shown) may be formed behind the display unit 1120. In this case, the air sucked from the inflow hole 1071 may be discharged into the housing 1010.

  Specifically, the fan case 1062c that houses the airflow control fan 1060c includes an opening 1063c through which air is discharged from the airflow control fan 1060c formed behind the display unit 1120, that is, inside the housing 1010, and the airflow control fan. A fourth passage (not shown) may be provided so as to connect the opening 1063c of 1060c to a discharge hole 1072c formed in the housing 1010.

  FIG. 51 is a cross-sectional view taken along line II-II specified in FIG. FIG. 52 is a bottom view of the intermediate housing shown in FIG. FIG. 53 is an embodiment of the intermediate housing of FIG. FIG. 54 is an embodiment of the intermediate housing of FIG. FIG. 55 is an embodiment of the intermediate housing of FIG. FIG. 56 is an embodiment of the bottom housing of FIG.

  Referring to FIGS. 51 and 52, the intermediate housing 1012 may further include a section 1012 a that divides the guide path 1070.

  Specifically, the intermediate housing 1012 may include a section 1012a that divides the first passage 1070a poured into the inflow hole 1071. The partitions 1012a may be arranged to correspond to the number of bridges 1100. The section 1012a may be disposed at an intermediate point between the plurality of bridges 1100 on the first path 1070a in order to symmetrically partition the first path 1070a with respect to each bridge 1100. The section 1012a may divide a guide path 1070 formed between the plurality of airflow control fans 1060.

  Specifically, as shown in FIG. 51, when three bridges 1100 ′, 1100 ″, 1100 ′ ″ are arranged, the section 1012a is between the bridges 1100 ′, 1100 ″, 1100 ′ ″. It may be arranged at an intermediate point. Accordingly, in the first passage 1070a, the air flowing through the inflow hole 1071 flows to a portion corresponding to the driving status of the airflow control fan 1060 disposed at one end of each bridge 1100 ′, 1100 ″, 1100 ″ ′. As described above, the first portion P1, the second portion P2, and the third portion P3 may be partitioned.

  Specifically, if the airflow control fan 1060 positioned at one end of the first bridge 1100 ′ is driven, only the portion of the air discharged through the exhaust port 1021 corresponding to the first portion P1 passes through the inflow hole 1071. It flows into the first passage 1070a. If the airflow control fan 1060 positioned at one end of the second bridge 1100 ″ is driven, only the portion of the air discharged through the exhaust port 1021 corresponding to the second portion P2 passes through the inflow hole 1071 to the first passage 1070a. Flow into. When the airflow control fan 1060 positioned at one end of the third bridge 1100 ″ ″ is driven, the air discharged through the exhaust port 1021 corresponding to the third P3 flows into the first passage 1070 a through the inflow hole 1071. The airflow control fans 1060 disposed adjacent to each bridge 1100 ′, 1100 ″, 1100 ″ ″ may be driven independently of each other. Therefore, for the AC shown in FIG. 26, the discharged airflow may be generated independently in three directions relative to the bridge 1100.

  Thus, in the embodiment shown in FIG. 51, as many different airflows as the predetermined number of sections partitioned for the bridges 1100 ′, 1100 ″, 1100 ″ ″ may be generated.

  The intermediate housing 1012 may include a guide portion 1017 formed at the other end of the bridge 1100 opposite to one end where the airflow fan 1060 is positioned. The guide portion 1017 may be disposed at the other end of the bridge 1100, and air sucked around the exhaust port 1021 may flow in. The guide portion 1017 may be formed at a point where the first passage 1070a and the second passage 1070b are joined. The guide portion 1017 prevents the air from flowing from the first passage 1070a disposed on the left side and the right side with respect to the bridge 1100 by preventing a collision when the air merges. Guide air moving to the bridge 1100. In other words, the guide portion 1017 may guide air flowing in through the inflow hole 1071 in order to smoothly flow from the first passage 1070a to the second passage 1070b. The guide portion 1017 protrudes from the outer peripheral surface of the intermediate housing 1012 so as to form a curved surface having a symmetrical shape.

  Referring to FIG. 53, each of the compartments 1012b may also be positioned a predetermined distance from an intermediate point on the first passage 1070a between the bridges 1100. In other words, the compartment 1012b may be positioned closer to one of the bridges 1100.

  Referring to FIG. 54, each of the sections 1012c may be positioned at a point where the bridge 1100 and the first passage 1070a meet. Specifically, the section 1012c may be disposed at the right end of the bridge 1100. In this case, the guide portions 1017 c each form a curved surface at the right end with respect to the bridge 1100 so that air flowing in from the first passage 1070 a formed on the left side of the bridge 1100 is guided to the bridge 1100. Protruding.

  In the embodiment shown in FIG. 54, different airflows may be generated for the exhaust ports 1021 between the plurality of bridges 1100.

  Referring to FIG. 55, the section 1012 d may also be disposed at the left end of the bridge 1100. In this case, the guide portions 1017d each form a curved surface at the left end with respect to the bridge 1100 so that air flowing in from the first passage 1070a formed on the right side of the bridge 1100 is guided to the bridge 1100. So that it protrudes.

  In the case of the embodiment shown in FIG. 55, different airflows may be generated for the exhaust ports 1021 between the plurality of bridges 1100.

  Referring to FIG. 56, the compartment 1012a and the guide portion 1017e may be disposed within the bottom housing 1013. In this case, the position of the section 1012e and the shape of the guide portion 1017e may be determined as described above with reference to FIGS.

The auxiliary inlet 1083 may be disposed on the outer peripheral surface of the upper housing 1011. The auxiliary inlet 1083 may be built in the ceiling C. The auxiliary air inlet 1083 may be disposed outside the ceiling C. The outside air sucked through the auxiliary intake port 1083 may be exhausted through the exhaust port 1021 after passing through the heat exchanger 1030.

  As described above, the AC 1001 according to the present disclosure prevents the air discharged from the exhaust port 1021 from being sucked again into the intake port 1020, thereby preventing condensation from forming inside the housing 1010. The effective performance of the AC 1001 felt by the user may be improved by reducing the loss of airflow.

Good. In other words, the exhaust port 2033 may be defined as a gap formed between the inner peripheral surface of the first outer housing 2031a and the outer peripheral surface of the first bottom inner housing 2031b from the opening of the intermediate housing 2021.

  However, the exhaust port 2033 is not limited to this, and is formed on the bottom housing 2030. Any air that has been heat-exchanged from the heat exchanger 2080 and is poured into the outside so as to be discharged from the bottom housing 2030 may be used. It may be a space or an opening.

  With this structure, the AC indoor unit 2001 may suck the air at the bottom, cool or heat the air, and discharge the cooled or heated air to the bottom.

  The Coanda curved portion for guiding the air discharged through the exhaust port 2033 may be formed on the inner peripheral surface of the first bottom outer housing 2031a. The Coanda curved portion 2034 may guide the airflow discharged through the exhaust port 2033 so that the Coanda curved portion 2034 flows in close contact with the Coanda curved portion 2034.

  The filter 2017 may be assembled to the upper part of the suction panel 2015 in order to filter and remove dust from the air sucked into the suction grill 2016.

  In the central portion of the second bottom housing 2032, the suction guide 2100 may be formed to guide air to pass through the suction panel 2015 and move to the blower fan 2040. As described above, the opening is formed in the center portion of the second bottom housing 2032 and the suction guide 2100 guides the second bottom housing 2032 so that air flows into the opening and moves to the blower fan 204. It may be arranged on the opening.

  When viewed from the vertical direction, the heat exchanger 2080 may have a substantially circular shape.

  The heat exchanger 2030 may be installed on the drain tray 2090 such that condensed water generated in the heat exchanger 2080 is collected in the drain tray 2090.

  The blower fan 2040 may be positioned on the radially inner side of the heat exchanger 2080. The blower fan 2040 may be a centrifugal fan that sucks air in the axial direction and releases air in the radial direction. The AC indoor unit 2001 may include a blower motor 2041 that drives the blower fan 2040. A blower fan inflow hole 2042 that moves air sucked from the intake port 2011 to the blower fan 2040 may also be included.

  With such a configuration, the AC indoor unit 2001 may suck indoor air, cool or heat the air, and then release the cooled or heated air to the room again.

  The AC room interior 2001 may further include an airflow control device 2050 that controls the discharged airflow.

  The airflow control device 2050 may control the direction of the discharged airflow by sucking air around the exhaust port 2033 in order to change the pressure. Further, the airflow control device 2050 may control the air suction amount around the exhaust port 2033. In other words, the airflow control device 2050 may control the direction of the discharged airflow by controlling the air suction amount around the exhaust port 2033.

  Here, controlling the direction of the discharged airflow means controlling the angle of the discharged airflow.

  When the air around the exhaust port 2033 is sucked, the airflow control device 2050 may suck air from one side in the direction in which the discharged airflow flows.

  Specifically, as shown in FIG. 64, when the airflow control device 2050 is driven, when considering that the direction in which the discharged airflow flows is indicated as the direction A1, the airflow control device 2050 is one side of the direction A1. The air may be driven to change the direction in which the discharged air flows to the direction A2.

  At this time, the direction change angle may be controlled based on the air suction amount. For example, the smaller the air suction amount, the smaller the direction change angle, and the larger the air suction amount, the larger the direction change angle.

  The airflow control device 2050 may discharge the sucked air to the side opposite to the direction A1 in which the discharged airflow flows. By doing so, the airflow may be controlled more smoothly by widening the airflow discharge angle.

  The airflow control device 2050 may suck air from the outside of the exhaust port 2033 in the radial direction. Thus, since the airflow control device 2050 sucks air from the outside of the exhaust port 2033 in the radial direction 21, the discharged airflow may spread widely from the outside of the exhaust port 2033 in the radial direction to the outside in the radial direction.

  The airflow control device 2050 includes an airflow control fan 2060 that generates a suction force for sucking air around the exhaust port 2033, an airflow control motor 2061 that drives the airflow control fan 2060, an airflow fan 2060, and an airflow control motor 2061. An airflow control fan case 2062 to be covered and a guide path 2070 for guiding the air sucked by the airflow control fan 2060 may be included.

  The airflow control fan 2060 may be housed in the bottom housing 2030. Specifically, the airflow control fan case 2062 may be disposed in a space formed in the first bottom outer housing 2031a. However, the present invention is not limited to this, and the airflow control fan 2060 may be disposed inside the bottom housing 2030, and similarly to the first bottom outer housing 2031a, the first bottom inner housing 2031b or the second bottom housing. You may arrange | position in the space formed in 2032.

  In the present embodiment, three airflow control fans 2060 each formed at 120 degrees may be provided. The airflow control fans 2060 are not limited to this, and a larger number of airflow control fans 2060 may be designed in various arrangements, or a smaller number of airflow control fans may be designed.

  In the present embodiment, the airflow control fan 2060 corresponds to a centrifugal fan, but is not limited to this, and the airflow control fan 2060 also uses various fans such as an axial flow fan, a cross flow fan, and a mixed flow fan. May be.

  The guide path 2070 connects the inflow hole 2071 that sucks air around the exhaust port 2033 to the discharge hole 2072 that discharges the sucked air.

  The inflow hole 2071 may be formed on the Coanda curved portion 2034 of the first bottom housing 2031.

  The discharge hole 2072 may be positioned around the exhaust port 2033 on the opposite side of the inflow hole 2071. Specifically, the discharge hole 2072 may be formed in the second bottom housing 2032.

  As described above, this structure may allow the airflow control device 2050 to discharge the air sucked in the direction opposite to the direction A1 in which the discharged airflow flows, and widen the discharge angle of the airflow. Thus, the airflow may be controlled more smoothly.

  The guide path 2070 is formed in the circumferential direction of the housing 2010. The first path 2070a poured into the inflow hole 2071, the second path 2070b extending radially inward from the first path 2070a, and the airflow control fan 2060 are safely received. And a third passage 2070c formed in the region.

  Accordingly, the air sucked through the inflow hole 2071 may be discharged from the discharge hole 2072 through the first passage 2070a, the second passage 2070b, and the third passage 2070c.

  The guide path 2070 may be formed by the intermediate housing 2021, the first bottom housings 2031 a and 2031 b, and the second bottom housing 2032. Specifically, the first passage 2070a and the second passage 2070b may be formed in an internal space formed by the intermediate housing 2021 and the first bottom housings 2031a and 2031b, and the third passage 2070c is formed in the second bottom portion. It may be formed in an internal space formed by the housing 2032 and the airflow control fan case 2062.

  However, the structure of the guide path 2070 is merely an example, and the structure, shape, and arrangement of the guide path 2070 are not limited as long as the guide path 2070 connects the inflow hole 2071 and the discharge hole 2072.

  In the first bottom outer housing 2031a, a bridge 2074 arranged to define the exhaust passage 2033 and form the second passage 2070b may be provided. In this embodiment, three bridges are provided.

  With this structure, the AC indoor portion according to the embodiment of the present disclosure is not accompanied by a blade structure as compared with a conventional AC indoor portion in which a blade is provided at an exhaust port and an air flow is controlled by rotation of the blade. The discharged airflow may be controlled. Therefore, since there is no interference by the blade, the discharge amount may be increased and the circulating noise may be reduced.

  Further, in contrast to a conventional AC room interior that has an exhaust port that must be formed in a linear shape to rotate the blade, the AC room interior according to embodiments of the present disclosure may be formed in a circular shape. By having a good exhaust port and thus the housing and heat exchanger are also formed in a circular shape, the aesthetics of the appearance may be improved by varying the design. Further, considering that the shape of a typical blower fan is circular, in the embodiment of the present disclosure, air flows more naturally and pressure loss is reduced, and as a result, AC cooling performance or heating performance is reduced. It may be improved. Hereinafter, the suction guide unit 2100 that guides air so as to be sucked into the AC room 2001 will be described in detail.

  FIG. 65 is a perspective bottom view of an AC separation / suction panel according to an embodiment of the present disclosure. FIG. 66 is a partial cross-sectional view of an AC suction guide unit according to an embodiment of the present disclosure. FIG. 67 is an exploded view of several portions of an AC according to an embodiment of the present disclosure.

  Referring to FIG. 65, the suction guide part 2100 that guides the outside air flowing into the housing 2010 may be disposed between the intake port 2011 and the blower fan inflow hole 2042.

  The suction guide unit 2100 extends from the intake port 2011 and the blower fan inflow hole 2042 so that outside air may pass through the intake port 2011 and flow into the blower fan 2040, whereby the intake port 2011 and the blower fan 2040. May be arranged in the form of a tube.

  The suction guide unit 2100 may include a guide surface 2110 that extends from the intake port 2011 to the blower fan inflow hole 2042 and has a curved shape.

  The guide surface 2110 is a part of the inner peripheral surface of the suction guide portion 2100, may include the outer peripheral surface of the intake port 2011, and may be formed in an annular shape that extends to the blower fan inflow hole 2042. Further, the guide surface 2110 may pass through an opening 2091 formed in the central portion of the drain tray 2090 and extend from the intake port 2011 to the blower fan inflow hole 2042.

  The air sucked through the intake port 2011 may be heat-exchanged by the heat exchanger 2080 after being guided by the guide surface 2110 so as to flow into the blower fan 2040. That is, the space formed by the guide surface 2110 may be a suction path 2120 through which air flows.

  The suction guide 2100 may include a rounded portion 2111 that is rounded and curved between the air inlet 2011 and the blower fan inflow hole 2042. Specifically, as illustrated in FIG. 65, the rounded portion 2111 may be formed so as to be rounded from the air inlet 2011 to the drain tray 2090 toward the inside of the housing 2010.

  The guide surface 2110 may include a rounded portion 2111 and may extend to a side adjacent to the blower fan inlet hole 2042. Specifically, the guide surface 2110 may be defined as the inner peripheral surface of the suction guide portion 2100 extending from the rounded portion 2111 to the blower fan inflow hole 2042.

  The suction path 2120 may be formed by a rounded portion 2111 so as to have a streamline shape in order to promote smooth air circulation from the intake port 2011 to the blower fan inflow hole 2042.

  The rounded portion 2111 may be formed such that the cross-sectional area of the suction path 2120 formed adjacent to the intake port 2011 is larger than the cross-sectional area of the suction path 2120 formed on the drain tray 2090 side.

  Specifically, the suction path 2120 may have a curved surface in which the rounded portion 2111 is convex toward the inside of the housing 2010 with respect to the rotation axis of the blower fan 2040 and is adjacent to the blower fan inflow hole 2042. The radius of the guide surface 2110 formed in this manner extends less than the radius of the guide surface 2110 formed adjacent to the intake port 2011.

  The rounded portion 2111 is not limited to this, and may be formed in a rounded shape extending from the air inlet 2011 to a position where the blower fan inflow hole 2042 is positioned. A curved surface recessed inward may be included.

  The rounded portion 2111 may start bulging from the side adjacent to the air inlet 2011 and stop bulging between the air inlet 2011 and the drain tray 2090.

  Specifically, one side of the rounded portion 2111 may be in a region disposed above the air inlet 2011, and the other side of the rounded portion 2111 may be between the air inlet 2011 and the drain tray 2090. The other side is inflated to be rotated 90 degrees from one side of the rounded portion 2111.

  However, the rounded portion 2111 is not limited to this. For example, the rounded portion 2111 may start to bulge from the intake port 2011, and the other side of the rounded portion 2111 passes through the drain tray 2090 so that the bulge communicates from the intake port 2011 to the blower fan inflow hole 2042. The fan fan inlet hole 2042 may be disposed.

  Due to the rounded portion 211, the guide surface 2110 does not have a surface perpendicular to the rotation axis of the blower fan 2040, thereby promoting a smooth air flow.

  Since the suction guide portion 2100 passes through the drain tray 2090 and extends from the intake port 2011 to the blower fan inflow hole 2042, the drain tray 2090 may not be exposed to the outside by being covered by the suction guide portion 2100.

  Specifically, the outer peripheral surface of the suction guide portion 2100 may be formed in a direction facing the inner peripheral surface of the housing 2010 so as not to be exposed to the outside, and the inner peripheral surface of the suction guide portion 2100 is externally provided. Since it arrange | positions with the form poured into the air blower fan 2040, it does not need to be exposed outside. Therefore, the drain tray 2090 may be disposed outside the outer peripheral surface of the suction guide portion 2100 so as not to be exposed to the outside.

  In other words, the drain tray 2090 may not be disposed on the suction path 2120 formed by the guide surface 2110 positioned on the inner peripheral surface of the suction guide portion 2100. That is, the guide surface 2110 may be formed in order to arrange the suction path 2120 and the drain tray 2090 separately.

  In the case of conventional AC, a part of the drain tray is positioned in the suction path so as to interfere with the airflow. In particular, in the case of a part of the drain tray arranged to be perpendicular to the rotation axis of the blower fan, the amount of air flowing into the blower fan is reduced by blocking the flow of the sucked air, and the drain tray This will cause noticeable noise due to collisions.

  In contrast, in one embodiment of the present disclosure, the suction guide 2100 separates the drain tray 2090 from the suction path 2120, which may eliminate the above-described problems that occur with conventional AC.

  In particular, in addition to separating the drain tray 209, the rounded portion 2111 may be disposed in a section that covers the drain tray 2090 to facilitate a smooth air flow to the blower fan 2040 without blocking the air flow. Good.

  Further, as described later, the built-in portion of the AC indoor portion 2001 such as the control case 2200 may be disposed on the edge side of the opening 2091 and covered with the suction guide portion 2100 so as not to be disposed in the suction path 2120. .

  The built-in portions such as the drain tray 2090 and the control case 2200 are covered with the suction guide portion 2100, and the surface formed in the suction path 2120 so as to be perpendicular to the rotation axis of the blower fan 2040 is excluded. The friction noise may be minimized.

  In particular, according to an embodiment of the present disclosure, noise generated in the suction path 2120 is generated when the suction guide unit 2100 is assembled and the AC chamber interior is compared to when the suction guide unit 2100 is removed and the AC chamber interior 2001 is driven. When 2001 is driven, it may be reduced by about 1.5 dB.

  The suction guide unit 2100 will be described from several viewpoints. An opening on the blower fan 2040 side formed so that air is sucked into the blower fan 2040 is defined as a first intake port 2042a. An opening formed on the housing 2010 so as to flow inward is defined as a third air inlet 2011a, and is formed in the drain tray 2090 so that air sucked through the third air inlet 2011a passes through the drain tray 2090. The opening may be defined as the second air inlet 2091a.

  The suction guide portion 2100 extends from the first intake port 2042a side to the third intake port 2011a side, and is disposed so as to pass through the second intake port 2091a formed between the first intake port 2042a and the third intake port 2011a. (See FIG. 61).

  Since the suction guide portion 2100 passes through the second intake port 2091a, the suction guide portion 2100 has a drain 2090 disposed outside the outer peripheral surface of the suction guide portion 2100, which is formed by the inner peripheral surface of the suction guide portion 2100. The separation from the suction path 2120 is made possible.

  Further, the third intake port 2011a may be formed by a rounded portion 2111 so that the radius is larger than that of the first intake port 2042a, and the second intake port 2091a formed therebetween is the third intake port 2011a. The radius becomes smaller.

  Hereinafter, an embodiment of the suction guide 2100 'will be described. Features other than the suction guide 2100 'and the drain tray 2090', which will be described later, are the same as the features of the above-described embodiment, and thus description thereof is omitted.

  FIG. 68 is a cross-sectional view of a part of an AC suction guide according to an embodiment of the present disclosure.

  The suction guide 2100 ′ has a drain tray 2090 ″ from one side where the air inlet 2011 is arranged so that the outside air flows to the blower fan 2040 through the air inlet 2100 via the suction guide 2100 ′ and the drain tray 2090 ′. By extending to the other side where it is positioned, it may be arranged in the form of a tube between the inlet 2011 and the drain tray 2090 ′.

The other side of the suction guide 2100 ′ is connected to the opening 2091 ′ of the drain tray 2090 ′, and the guide surface 2100 ′ inside the housing 2010.
In addition, a tube shape connected to the opening 2091 ′ may be formed.

  In other words, unlike the suction path described in the above embodiment, the suction path 2120 ′ may be formed by a pair of the suction guide portion 2100 ′ and the drain tray 2090 ′. Specifically, since the guide surface 2110 ′ extends from the rounded portion 2111 to one side of the inner peripheral surface of the opening 2091 ′ of the drain tray 2090 ′, the suction path 2120 ′ extends along the guide surface 2110 ′. It may be formed in a section extending to the other side of the inner peripheral surface of the opening 2091 '.

  The suction guide portion 2100 ′ may be disposed so as to contact one side of the inner peripheral surface of the opening 2091 ′ of the drain tray 2090 ′ without any gap. Accordingly, air may be guided and moved from the intake port 2011 to the blower fan 2040 through the suction path 2120 ′.

  Since one side of the inner peripheral surface of the opening 2091 ′ contacts the guide surface 2110 ′ without a gap, the side of the guide surface 2110 ′ in contact with the opening 2091 ′ and one side of the inner peripheral surface of the opening 2091 ′ have the same size. May have a radius of. Therefore, since there is no structure formed in the suction path 2120 ′ so as to be perpendicular to the rotation axis of the blower fan 2040, air flows into the blower fan 2040 without causing resistance to fluidity. Good.

  The other side of the inner peripheral surface of the opening 2091 ′ extends toward the blower fan inflow hole 2042, thereby allowing air to flow into the blower fan 2040.

  Accordingly, unlike the above-described embodiment, even if the drain tray 2090 'is exposed to the suction path 2120', the air may be guided to the blower fan without resisting the fluidity of the air.

  In other words, in the case of a conventional AC, the portion of the drain tray disposed in the suction path interferes with the air fluidity, but according to an embodiment of the present disclosure, the problem that occurs in the conventional AC is that the drain tray 2090 ′ May be eliminated by forming a suction path 2120 ′ that includes a streamline feature with a suction guide 2100 ′ that does not interfere with air fluidity.

  Hereinafter, the control case 200 will be described in detail.

  FIG. 69 is a development view of a control case according to an embodiment of the present disclosure. FIG. 70 is a sketch of a printed circuit board (PCB) according to an embodiment of the present disclosure. FIG. 71 is a schematic diagram of a PCB assembled in a lower case of a control case according to an embodiment of the present disclosure. 72 to 75 show a wire held by a wire holder according to an embodiment of the present disclosure.

  66 to 69, the control case 2200 may be disposed on the edge side of the opening 2091 of the drain tray 2090.

  The control case 2200 may include a curved portion 2250 corresponding to the outer peripheral surface of the opening 2091. This prevents the control case 2200 from being disposed in the suction path 2120 while being disposed on the outer peripheral surface of the opening 2091.

  Specifically, the curved portion 2250 of the control case 2200 is arranged so as to correspond to the edge side of the opening 2091, and the portion of the control case 2200 arranged outside the drain tray 2090, particularly inside the opening 2091 is arranged. You may make it disappear.

  In the case of the conventional AC, the control case may be disposed on the drain tray as in the embodiment of the present disclosure, but the control case has a box shape, and a part thereof is exposed to the outside of the drain tray. By being positioned in the suction path 2120, the fluidity of air is interfered, noise is generated, and the amount of fluid is reduced.

  Such a problem may be solved in the embodiment of the present disclosure. In this case, the control case 2200 is not exposed to the outside of the drain tray 2090 and is not positioned in the suction path 2120.

  Furthermore, since the control case 2200 includes the curved portion 2250, the control case 2200 may be covered by the suction guide portion 2100. Specifically, the curved portion 2250 may be formed to correspond to the outer peripheral surface of the opening 2091 and to correspond to the outer peripheral surface of the suction guide portion 2100.

  Since the outer peripheral surface of the suction guide portion 2100 passes through the opening 2091, it may have a radius of curvature corresponding to the inner peripheral surface of the opening 2091, and the curved portion 2250 has a radius of curvature corresponding to the outer peripheral surface of the opening 2091. Since the curved surface is included, the outer peripheral surface of the suction guide portion 2100 and the curved portion 2250 may include each curved surface in a corresponding form.

  Due to the curved portion 2250, the suction guide portion 2100 does not have a portion where the control case 2200 protrudes inside the suction guide portion 2100, so that the inner peripheral surface of the stream line form as a whole without any further change in shape. May be arranged.

  The control case 2200 may be disposed on the outside of the exhaust port 2091 in the radial direction so as to be positioned on the drain tray 2090, and between the intake port 2011 and the drain tray 2090 with respect to the vertical direction of the AC chamber interior 2001. It may be arranged.

  As described above, since the rounded portion 2111 of the suction guide portion 2100 is formed between the intake port 2011 and the drain tray 2090, the control case 2200 further includes a curved portion 2250 corresponding to the rounded portion 2111 in the vertical direction. May be included.

  Specifically, when the curved portion 2250 corresponding to the opening 2091 is referred to as the first curved portion 2251, the control case 2200 may include a second curved portion 2252 having a curved surface corresponding to the rounded portion 2111 in the vertical direction. .

  The control case 2200 may be covered by the second curved portion 2252 with the suction guide 2100. Since the second curved portion 2252 has a curved surface corresponding to the rounded portion 2111, the control case 2200 may be disposed near the outer peripheral surface of the suction guide portion 2100.

  Therefore, since the suction guide 2100 does not have a portion in which the control case 2200 protrudes inside the suction guide 2100 in the vertical direction, the inner peripheral surface of the stream line form as a whole without any further shape change. It may be arranged to have.

As shown in FIG. 69, the control case 2200 includes an upper case 2210 having a first curved portion 2251 and a second curved portion 2252, a lower case 2220 having a first curved portion 2251, an upper case 2210, and a lower case 2220. And a PCB 2230 disposed therebetween.

  As shown in FIG. 70, the PCB 2230 may include a first curved portion 2251. This is because the shape of the entire control case 2200 is maintained because the PCB 2230 is assembled in the cases 2210 and 2220.

  However, unlike the embodiment of the present disclosure, since the PCB 2230 has a smaller area than the cases 2210 and 2220, the PCB 2230 may be arranged with only the first curved portion 2251 if the PCB 2230 is disposed only in a part of the inner region of the cases 2210 and 2220. It does not have to be included.

  As shown in FIG. 71, a wire holder 2260 that holds a wire 2231 extending from the PCB 2239 may be formed in the lower case 2220.

  The PCB 2230 may be electrically connected to the internal components of the AC room interior 2001 with wires 2231 in order to control the internal components. Otherwise, if the wires 2231 are mounted randomly in the cases 2210 and 2220, they are susceptible to damage. Therefore, the wire holder 2260 may be arranged such that the wires 2231 are arranged with order.

  The wire holder 2260 may be mounted on one side or both sides of a space where the PCB 2230 is disposed in the lower case 2220. A part of the entire wire 2231 extending to either side of the PCB may be held by the wire holder 2260, and the other may extend to the outside of the cases 2210 and 2220.

  The wire holder 2260 may be formed by three hooks 2261, 2262, and 2263 arranged in a triangular shape. However, this is not limited to this embodiment, and may be formed by two hooks or four or more hooks.

  Considering that the first hook 2261 is disposed at the top, the second hook 2262 is disposed at the bottom left side, and the third hook 2263 is disposed at the bottom right side with respect to the triangular arrangement, each hook 2261, 2262, The protrusion of 2263 may be arranged toward the center of the triangular arrangement.

  Passing areas 2264, 2265, and 2266 may be formed between the hooks 2261, 2262, and 2263 through which the wire 2231 passes.

  A space between the first hook 2261 and the second hook 2262 is defined as a first passage region 2265, and a space between the second hook 2262 and the third hook 2263 is defined as a second passage region, When the space between the first hooks 2261 is defined as the third passage region 2266, the wire 2231 passes through at least two different passage regions among the three passage regions 2264, 2265, and 2266, and the case 2210, It may extend to the inside of 2220.
