Description

  The present invention relates to an indoor unit of an air conditioner in which a louver drive motor that rotationally drives a louver provided at an outlet and a drain hose connected to a drain pan are in close contact, and in particular, from a drain hose to a louver drive motor. The present invention relates to a structure that prevents adhesion of dew condensation on the surface.

  In an indoor unit of an air conditioner, a suction port is opened at the front and top surfaces of an indoor unit body that is a casing, and a blow-out port is opened at the lower part of the front surface. A heat exchanger is disposed inside the indoor unit main body facing the suction port, and a blower is disposed between the heat exchanger and the outlet.

  A louver is rotatably supported at the outlet. In the louver, two types of louvers, that is, left and right louvers that guide heat exchange air in the left and right direction from the outlet and an upper and lower louver that guides heat exchange air in the up and down direction from the outlet, are separated from each other or integrally. Provided.

  Usually, two sets of left and right louvers are provided on the left and right sides of a substantially intermediate portion in the width direction of the outlet, and a louver drive mechanism and a louver drive motor that rotationally drive each set of louvers are provided on both left and right sides of the outlet. One set of upper and lower louvers is provided over the entire width direction of the outlet, and a louver drive mechanism and a louver drive motor connected to the upper and lower louvers are provided on one side of the outlet.

  In addition, a drain pan is provided at the lower end of the heat exchanger, and receives drain water that is generated and dripped by the heat exchanger during the refrigeration cycle operation. A drain hose is connected to the drain pan and bundled together with the refrigerant pipes and cable wires that connect the indoor unit and the outdoor unit, and is extended from one side of the outdoor unit body to the outside to drain water to the outside. Guide the discharge.

  In addition, the drain water produced | generated with a heat exchanger is low temperature, and it is easy to produce dew condensation on the surface of a drain pan and a drain hose. A heat insulating material such as a styrene foam material is adhered to the back surface of the drain pan to prevent condensation on the back surface of the drain pan.

  Although the drain hose is composed of a heat insulating tube, since the pipe is cooled by the cooled drain passing through the inside, condensation may occur on the surface when the room is hot and humid.

  And the drain hose is attached to the position adjacent to one louver drive motor of the left-right louver and upper-lower louver arrange | positioned at the blower outlet one side part. If the surface of the drain hose is in a wet state due to condensation or the like, there is a possibility that moisture will adhere to the louver drive motor side that is an adjacent electrical component. Therefore, it is not preferable when the safety of electrical parts is taken into consideration.

  By the way, what was described in Japanese Patent Application Laid-Open No. 10-110970 is structurally considered so that even if condensed water is generated on the drain hose surface, it does not adhere to the louver drive motor.

  In the configuration described in Japanese Patent Application Laid-Open No. 10-110970, the side surface portion of the rear main body constituting the indoor unit main body is formed into a two-stage shape including an upper side surface portion and a lower side surface portion.

A louver drive motor is attached to the outer surface of the lower side surface, and a part of the heat exchanger, a drain pan, and a drain hose are located inside the lower side surface.

  Further, a drain hose connection confirmation hole is provided in the lower side surface. If you look through the hole before assembling the front panel to the rear body, you can check the drain hose connection. Therefore, water leakage due to poor connection of the drain hose to the drain pan can be reliably prevented.

  According to the technique described in Japanese Patent Application Laid-Open No. 10-110970, the lower side surface portion of the rear main body is interposed between the drain hose and the louver drive motor. When condensation is generated on the drain hose surface, It is possible to prevent condensation from adhering to the louver drive motor.

  However, in the configuration described in Japanese Patent Laid-Open No. 10-110970, it is necessary to provide the drain hose position and the louver drive motor position at positions shifted in the width direction of the indoor unit main body. Of course, there is a problem that the size in the width direction of the indoor unit main body, which is the casing, must be increased accordingly, and the casing width dimension cannot be reduced.

  The present invention has been made based on the above circumstances, the purpose of which is to reduce the width of the indoor unit body, even when the drain hose and the louver drive motor are arranged adjacent to each other, An air conditioner indoor unit that improves the safety by reliably preventing condensation generated on the surface of the drain hose from adhering to the louver drive motor, eliminating the cause of electrical problems caused by moisture adhesion. It is something to be offered.

  In order to satisfy the above object, the indoor unit of the air conditioner of the present invention has a suction port and a blower opening in the indoor unit body, accommodates a heat exchanger and a blower inside, and a louver can be freely rotated to the blowout port. The direction of the heat exchange air from the air outlet is supported, the louver drive motor is connected to the louver via the drive mechanism, and a drain pan is installed at the lower end of the heat exchanger. The drain water that is generated and dripped is connected, the drain hose is connected to the drain pan, and the drain water received by the drain pan is extended to a position adjacent to the louver drive motor, and the motor cover is connected to the drain hose and the louver drive motor. Is prevented from adhering to the louver drive motor due to the condensation formed on the surface of the drain hose.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view schematically showing an indoor unit of an air conditioner when the refrigeration cycle operation is stopped, and FIG. 2 is a perspective view showing an appearance of the indoor unit during the refrigeration cycle operation.

  The indoor unit main body 1 includes a front panel 2 constituting a front case and a rear main body 3 constituting a rear case, and is formed in a horizontally long shape in the left-right width direction with respect to the vertical direction. A front suction port 4 is opened at a part of the front side of the indoor unit body 1, and a movable panel 2 </ b> A supported by an opening / closing drive mechanism is fitted into the front panel 2 facing the front suction port 4.

  When the refrigeration cycle operation is stopped, the movable panel 2 </ b> A is flush with the front panel 2 and closes the front suction port 4 to constitute a part of the appearance of the indoor unit body 1. When the refrigeration cycle operation is started, the panel opening / closing mechanism operates, and the movable panel 2A moves away from the front suction port 4 and protrudes to the front side.

  Therefore, a gap communicating with the room is formed around the movable panel 2A, and the front suction port 4 can be opened to the room. An upper surface suction port 5 is opened at the upper part of the indoor unit main body 1, and a frame-like bar partitioning into a plurality of spaces is fitted into the upper surface suction port 5.

  A blow-out opening 6 is opened in the lower part of the front surface of the indoor unit body 1, and a wind direction guide device F described later is provided in the blow-out opening 6. The air direction guide device F can open and close the air outlet 6 according to the rotation posture and set the air exchange direction of the heat exchange air according to the refrigeration cycle operating conditions.

  In the indoor unit main body 1, a heat exchanger 8 formed in a substantially inverted V shape by the front heat exchanger portion 8A and the rear heat exchanger portion 8B is disposed. The front heat exchanger portion 8A is formed in a curved shape so as to face the entire front suction port 4 and a part of the upper surface suction port 5, and the rear heat exchanger portion 8B is straight and obliquely inclined so as to face the upper surface suction port 5. Opposite part.

  An indoor fan 10 is disposed between the front and rear heat exchanger portions 8A and 8B of the heat exchanger 8. The indoor blower 10 includes a fan motor disposed in a space on one side end of the indoor unit main body 1 and a cross-flow fan connected to a rotation shaft of the fan motor. The length of the cross flow fan in the axial direction is set to be the same as the length of the heat exchanger 8 in the width direction and correctly opposes each other.

  The lower end portion of the front side heat exchanger portion 8A is placed on the front drain pan 12a, and the lower end portion of the rear side heat exchanger portion 8B is placed on the rear drain pan 12b. The front and rear drain pans 12a and 12b are formed integrally with the rear main body 3 constituting the indoor unit main body 1, respectively, and receive drain water dripped from the heat exchanger portions 8A and 8B.

  The front and rear drain pans 12a and 12b are communicated with each other via a flange provided over both side portions. Since the rear drain pan 12b is at a high position and the front drain pan 12a is at a low position, the drain water received by the rear drain pan 12b is guided to the front drain pan 12a, and all the drain water is collected in the front drain pan 12a.

  A connecting port protrudes from the left or right side end of the front drain pan 12a, and a drain hose described later is connected thereto. The drain hose is bundled together with the refrigerant pipes and cables that communicate the indoor unit with the outdoor unit, protrudes from either the left or right side of the indoor unit body according to the installation conditions of the indoor unit, and extends to the outside. It is.

  The outer surfaces of the side walls of the front and rear drain pans 12a and 12b are provided close to the indoor blower 10 and constitute a nose for the crossflow fan of the indoor blower 10. A partition wall member 14 connects the side wall portions of the front and rear drain pans 12a and 12b, which are noses, and the side portions of the outlet port 6.

  By driving the indoor blower 10, the space surrounded by the partition wall member 14 becomes a blowout ventilation path 15 </ b> A that communicates the nose and the blowout opening 6. On the other hand, a suction ventilation path 15 </ b> B is formed between the front suction port 4 and the upper suction port 5 and the heat exchanger 8.

  On the other hand, a frame assembly 16 is interposed between the upper surface inlet 5 of the front panel 2 and the upper end of the heat exchanger 8. An air filter cleaning unit S is attached along the front end of the frame assembly 16.

  An upper air filter 17 is movably supported on the upper surface of the frame assembly 16 on the upper side of the air filter cleaning unit S, and a front air filter 18 is mounted on the front surface of the frame assembly 16 on the lower side of the air filter cleaning unit S. It is supported movably.

  An ion generator M is provided in the suction ventilation path 15B between the front air filter 18 and the front heat exchanger section 8A. The ion generator M includes an ion generation electrode 20 and a counter electrode 21 that is a ground electrode, and the ion generation electrode 20 and the counter electrode 21 are configured to be attached to a case body 22.

  Next, the wind direction guide device F will be described. FIG. 3 is a perspective view showing a part (central part) of the wind direction guiding device F with the part omitted. As shown in FIGS. 1 to 3, the wind direction guide device F is attached to one upper and lower louvers 7 </ b> A supported so as to be rotatable in the vertical direction with respect to the outlet 6, and the upper surface of the upper and lower louvers 7 </ b> A. A plurality of left and right louvers 7B are provided that rotate in the vertical direction integrally with the upper and lower louvers 7A, and are supported so as to be freely rotatable in the left and right directions.

  Here, a set of a plurality of left and right louvers 7B on the left and right sides of a substantially intermediate portion in the left and right width direction of the upper and lower louvers 7A constitutes one set, and two sets of left and right louvers 7B are attached. The left and right louvers 7B of each set are configured to be rotationally displaced in the left or right direction simultaneously as described later.

  The upper and lower louvers 7A are connected to an upper and lower louver drive motor 30A provided on the left side of the outlet 6 and capable of rotating in the forward and reverse directions via an upper and lower louver drive mechanism 31A. The left and right louvers 7B of each set are connected to left and right louver drive motors 30B provided on the left and right sides of the outlet 6 via a left and right louver drive mechanism 31B.

  That is, the left and right louver drive mechanisms 31B and the left and right louver drive motors 30B are arranged on the right side of the outlet 6, whereas the left and right louver drive mechanisms 31B and the left and right louver drive motors 30B are arranged on the left side of the outlet 6. The upper / lower louver drive mechanism 31A and the upper / lower louver drive motor 30A are also arranged.

  The left and right louver drive mechanism 31B disposed on the right side of the outlet 6 is configured independently, but the left and right louver drive mechanism 31B disposed on the left side of the outlet 6 is configured integrally with the upper and lower louver drive mechanism 31A. ing.

  Next, the left and right louver drive mechanism 31B disposed on the right side of the outlet 6 will be schematically described. When the left and right louver drive motor 30B is rotationally driven in a predetermined direction, the drive gear attached to the rotary shaft moves the drive rod provided with the rack portion in the axial direction.

  The drive rod is inserted through a support rib provided at the right end of the upper and lower louvers 7A, and can move in the axial direction regardless of the rotation of the upper and lower louvers 7A. Along with the movement of the drive rod, the connecting rod moves in the width direction of the upper and lower louvers 7A via a connecting fixture provided on the upper and lower louvers 7A.

  All the left and right louvers 7B have one side portion that is rotatable with the upper and lower louvers 7A having a rotation fulcrum, and the other side portion engages with a long hole provided in the connecting rod. Therefore, when the connecting rod moves in one direction, the pair of left and right louvers 7B rotate in the moving direction of the connecting rod all around the rotation fulcrum.

  Note that the drive rod and the connecting fixture are integrally moved only in the axial direction and are connected so as to be idle in the circumferential direction, so that they are unrelated to the rotation of the upper and lower louvers 7A.

  Next, the left and right louver drive mechanism 31B and the upper and lower louver drive mechanism 31A that are arranged on the left side of the outlet 6 and are integrally configured will be schematically described.

  The left and right louver drive mechanism 31B used here has the same configuration as the left and right louver drive mechanism 31B disposed on the right side of the outlet 6 described above. However, a drive shaft is fitted in a part of the drive rod so as to be slidable along the axial direction of the drive rod and to be rotatable integrally with the drive rod.

  This drive shaft is provided with a gear and meshes with a drive gear attached to the rotary shaft of the upper and lower louver drive motor 30A. Further, a square shaft portion is provided at one end portion of the drive shaft, and is inserted into and engaged with a square hole provided in a support rib at the left end of the upper and lower louvers 7A.

  When the upper and lower louver drive motor 30A rotationally drives the gear, the drive shaft rotates in the same direction, and the upper and lower louvers 7A rotate in the same direction via the angular shaft portion of the drive shaft and the square holes of the supporting ribs. As described above, the drive shaft and the drive rod constituting the left and right louver drive mechanism 31B rotate integrally, and the drive rod itself is movable in the axial direction by itself.

  The connection fixture connected to the tip of the drive rod is slidable integrally along the axial direction of the drive rod, but is irrelevant to the circumferential direction and is configured so that the drive rod is idle. .

  By driving the upper and lower louver drive motor 30A, the upper and lower louver drive mechanism 31A acts to urge the upper and lower louvers 7A. At this time, unless the left and right louver drive motor 30B is driven, the left and right louver drive mechanism 31B The left and right louvers 7B do not rotate.

  On the contrary, if the left and right louver drive motor 30B is driven, the left and right louvers 7B are rotationally biased via the left and right louver drive mechanism 31B, and a state unrelated to the upper and lower louvers 7A is maintained.

  If the left and right louver drive motor 30B and the upper and lower louver drive motor 30A are driven simultaneously, the respective louver drive mechanisms 31B and 31A act simultaneously, and the left and right louver 7B and the upper and lower louver 7A are simultaneously urged to rotate.

  In particular, the left and right louver drive motors 30B provided on the left side of the outlet 6 and connected to the left and right louver drive mechanisms 31B and the upper and lower louver drive motors 30A connected to the upper and lower louver drive mechanisms 31A are in positions close to each other. Be placed.

  4 is a side view for explaining the relationship between the arrangement of the left and right louver drive motor 30B and the upper and lower louver drive motor 30A and the drain hose H, and FIG. 5 is a perspective view of the same configuration. Actually, the front panel 2 constituting the indoor unit main body 1 is removed, and after remaining, the side surface of the main body 3 is partially enlarged.

  A vertical louver drive motor 30A is attached to a substantially central portion of the figure, and a rotating shaft of the motor 30A penetrates the side surface portion of the rear main body 3 and protrudes to the inside, and is connected to the above-described vertical louver drive mechanism 31A.

  A left and right louver drive motor 30B is attached to the right side of the upper and lower louver drive motor 30A with a narrow gap, and the rotational axis of the drive motor 30B is parallel to the side surface of the rear body 3 and obliquely downward. Projecting to the left and right louver drive mechanisms 31B.

  Particularly, the upper and lower louver drive motor 30A is partially covered with a motor cover K described later. In other words, the upper and lower louver drive motor 30A is in contact with the inner surface (back surface) side of the motor cover K, and the drain hose H connected to one end of the front drain pan 12a is connected to the outer surface (front surface) side of the motor cover K. It touches.

  Without the motor cover K, the upper and lower louver drive motor 30A and the drain hose H are in adjacent positions. Thus, by arranging the drain hose H and the upper and lower louver drive motor 30 </ b> A at adjacent positions, the width of the indoor unit body 1 can be made compact. In addition, a motor cover K is inserted between the upper and lower louver drive motors 30 </ b> A and the drain hose H.

  Depending on the installation conditions of the indoor unit to the air-conditioned room, not only is the drain hose H connected to the left side of the front drain pan 12a as shown in the figure, but conversely, the drain hose H is connected to the right side of the front drain pan 12a. There is a possibility of connection.

  At this time, since the drain hose H is extended at a position adjacent to the left and right louver drive motor 30B provided on the right side of the outlet 6, it is natural that the gap between the left and right louver drive motor 30B and the drain hose H. The motor cover K is inserted in the middle.

  FIG. 6 is an external perspective view of the motor cover K. FIG. The motor cover K includes a cover portion Ka that is bulged and formed to cover a part of the upper and lower louver drive motor 30A or the left and right louver drive motor 30B. At one side end of the cover portion Ka, a mounting portion Kc provided with a mounting hole Kb is integrally projected at the upper portion of the figure. Further, a reinforcing flange Kd is integrally provided along the other side edge of the cover portion Ka.

  The cover part Ka is provided with a guide concave part Ke on the R surface (in the shape of a circular arc in a cross section) having a corner partly removed at the side end on the side of the flange part Kd and only at the upper end in the figure. The radius of curvature of the cross section of the guide recessed portion Ke is formed substantially the same as the radius of curvature of the drain hose H.

  The cover portion Ka of the motor cover K is covered with the upper and lower louver drive motor 30A, the mounting portion Kc is applied to the side surface portion of the rear body 3, a mounting screw is inserted into the mounting hole Kb, and the tip of the mounting screw is inserted into the rear body 3 The motor cover K can be attached to the rear main body 3 by being screwed into the screw holes on the side surfaces.

  Then, the front-end | tip part of the drain hose H is inserted in the connection port body protrudingly provided by the front drain pan 12a, and the drain hose H is connected to the front drain pan 12a.

  As shown in FIG. 7, if the motor cover K has no guide recess and the side end of the cover Ka is formed in a square shape, when the drain hose H is inserted into the connection mouth of the front drain pan 12a. The corner part of the cover part Ka gets in the way. As indicated by X in FIG. 7, the drain hose H and the motor cover K interfere with each other, and the drain hose H cannot be smoothly inserted and connected to the front drain pan 12a (deterioration of insertability).

  On the other hand, if the guide cover Ke is provided in the motor cover K, interference between the drain hose H and the motor cover K is eliminated, as indicated by Y in FIG. That is, by moving the distal end portion of the drain hose H along the guide concave portion Ke, the guide concave portion Ke serves as a guide for connecting the drain hose H, and the insertion property of the drain hose H is ensured.

  Next, the effect | action in the indoor unit of the air conditioner comprised in this way is demonstrated.

  When the user presses the operation button on the remote control (remote control panel), the indoor blower 10 is driven and the ion generator M is energized. Further, the compressor is driven in the outdoor unit communicating with the indoor unit through the refrigerant pipe, and the refrigeration cycle operation is started.

  The room air is sucked into the indoor unit main body 1 from the front suction port 4 and the upper surface suction port 5, guided along the suction ventilation path 15 </ b> B, and passes through the front air filter 18 and the upper surface air filter 17. At this time, dust contained in the room air is captured by the front air filter 18 and the upper air filter 17.

  The room air from which dust has been removed by the front air filter 18 and the upper air filter 17 is sterilized and deodorized by the action of the ion generator M. At the same time, the ion generator M also sterilizes indoor unit components. The cleaned indoor air flows through the heat exchanger 8, and heat exchange action is performed with the refrigerant led to the heat exchange air.

  Thereafter, the heat exchange air is guided along the blowout air passage 15A and blown into the room from the blowout port 6. At this time, as will be described later, the air is guided to the wind direction guide device F, and the efficient air-conditioning operation is continued.

  If the refrigeration cycle operation is continued for a long time, it is captured by the front air filter 18 and the upper air filter 17, and the amount of adhering dust increases, resulting in resistance to air circulation. Therefore, the air filter cleaning unit S is periodically operated to remove the dust adhering to the air filters 18 and 17 and discharge it to the outdoors.

  It should be noted that during the cooling operation and the heating operation, the attitude of the wind direction guiding device F may be adjusted and adjusted as described later.

  At the start of the cooling operation, the upper and lower louver drive motor 30A is driven, and when the upper and lower louver drive mechanism 31A makes the upper and lower louvers 7A in an oblique posture along the blowout air passage 15A, the drive of the upper and lower louver drive motor 30A is controlled to stop. .

  Next, while the refrigeration cycle action is performed, the left and right louver drive motor 30B is rotationally driven, and the left and right louver drive mechanism 31B including a drive rod, a connecting fixture, a connecting rod and the like is operated, and each set of left and right louvers 7B. Rotate simultaneously in the same direction.

  The left and right louver drive motor 30B is controlled to rotate in a predetermined direction for a predetermined time and then to rotate in a predetermined direction in the opposite direction. The connecting fixture and the connecting rod are reciprocated at predetermined time intervals, and accordingly, the plurality of left and right louvers 7B are pivotally driven in a predetermined direction and an anti-predetermined direction at the same time so as to perform a so-called swinging motion.

  The cold air blown out from the blowout port 6 during the refrigeration cycle operation is blown in the left and right directions by the left and right louvers 7B and reaches every corner in the room. In addition, the cool air is guided obliquely forward by the upper and lower louvers 7A and guided along the cross-sectional shape of the upper and lower louvers 7A.

  As a result, there is no wind separation and the airflow can be bent efficiently in the horizontal direction. The cold air is guided farther and further upward, so that the feet of the resident are not cooled directly away from the indoor floor surface. By providing such a wind direction guide device F, a comfortable cooling air-conditioning can be obtained.

  When the heating operation is selected, the upper and lower louver drive motor 30A is driven to bring the upper and lower louvers 7A into a substantially vertical posture via the upper and lower louver drive mechanism 31A including gears, drive shafts, and the like. Accordingly, the left and right louvers 7B are located on the back side of the upper and lower louvers 7A.

  While maintaining this posture, the heating refrigeration cycle operation is performed, and the left and right louver drive motor 30B is driven to rotate forward and backward. Further, the upper and lower louver drive motor 30A may be energized to swing the upper and lower louver 7A within a predetermined angle range.

  As the left and right louver drive motor 30B is driven, the left and right louvers 7B perform a so-called swinging motion, and guide the warm air blown from the outlet 6 to every corner of the room. Warm air is guided from the indoor unit to the floor in the room to warm the feet of the residents. By providing the wind direction guide device F, a comfortable heating air-conditioning system of so-called head cold foot heat can be obtained.

  In particular, during the cooling operation, the refrigerant guided to the heat exchanger 8 evaporates and takes away the latent heat of evaporation from the indoor air flowing therethrough. At this time, the room air changes to cool air and is dehumidified, dried, and blown out from the blow-out port 6.

  The moisture dehumidified from the indoor air remains in the form of water droplets and remains attached to the heat exchanger 8 and gradually enlarges. Finally, it flows down along the heat exchanger 8 and becomes drain water dripped onto the front and rear drain pans 12a and 12b.

  Because of the relationship between the mutual drain pans 12a and 12b communicating via the buttock and the height, all drains are collected in the front drain pan 12a. The amount of drain water dripped onto the front and rear drain pans 12a, 12b increases with the operation for a long time, and after being collected in the front drain pan 12a, is led to the drain hose H and discharged to the outdoors.

  During cooling and dehumidifying operations during the rainy season and summer, low-temperature drain water circulates inside the drain hose H, while humid air contacts the surface of the drain hose H, and this air condenses and forms condensation. Most likely to occur.

  However, a motor cover K is interposed between the drain hose H and the upper and lower louver drive motor 30A here. Condensation that wets the surface of the drain hose H is not blocked by the motor cover K and does not flow out to the upper and lower louver drive motor 30A side. Therefore, the safety of the upper and lower louver drive motor 30A can be ensured.

  Since the left and right louver drive motor 30B is located farther from the drain hose H than the upper and lower louver drive motor 30A, even if the motor cover K is not present, the left and right louver drive motor 30B is not affected by the condensation generated on the surface of the drain hose H.

  However, when the drain hose H is located adjacent to the upper and lower louver drive motor 30A provided on the right side of the outlet 6, it goes without saying that the motor cover K is interposed therebetween.

  In addition, although the wind direction guide apparatus F of embodiment mentioned above was made into the structure which provided the left-and-right louver 7B integrally in the upper-and-lower louver 7A, it is not limited to this, An upper-and-lower louver is used conventionally. The present invention can also be applied to a configuration in which the left and right louvers are provided in the vicinity of the outlet 6 and the drain hose is located at a position adjacent to any one of the louver drive motors.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments.

  According to the present invention, the drain hose and the louver drive motor are positioned adjacent to each other to reduce the width of the indoor unit main body, and reliably prevent the condensation generated on the drain hose surface from adhering to the louver drive motor. Thus, it is possible to eliminate the cause of electrical problems due to moisture adhesion and improve safety.
